However, in the component mounting apparatus described in Patent Document 1, since the connector is automatically connected only when the feeder bank 122 is raised, the power, signal, air, etc. are connected to the feeder bank 122 after the connector is connected. An operation to turn on the power switch for supplying the power is required separately. Thus, it is necessary to intervene the operator's operation, which is troublesome.
There is also a risk that the connector may be connected or removed by mistake with the power switch turned on. In this case, the life of the contact is consumed due to the occurrence of an arc or the like at the connector contact, or a circuit failure may be caused by the influence of voltage fluctuation due to chattering at the time of contact.
Therefore, an object of the present invention is to provide a component mounting apparatus including a component supply unit that can automatically turn on / off a power switch at an appropriate timing.

In order to solve the above-described problem, a component mounting apparatus according to claim 1 includes a main body portion and a component supply portion that is detachable from a predetermined set position of the main body portion, and a component supplied from the component supply portion. A component mounting apparatus for mounting at a predetermined position on a board, the component mounting apparatus being provided in the main body, and holding a part of the component supply unit so that the component supply unit can be placed at a predetermined work position for supplying the component.

It is characterized by.
In this way, the connection and disconnection of the connector and the device to be connected are performed with the power supply stopped, so that the life of the contact is consumed due to the occurrence of an arc or the like at the connector contact, or voltage fluctuation due to chattering at the time of contact It is possible to prevent a circuit failure from occurring due to the influence of the above.

In addition, since the power supply can be automatically started after connecting the connector and the device to be connected, an operation (power supply) for the operator to start the power supply after the connector and the device to be connected are connected. There is no need to switch on.
In other words, when setting the component supply unit on the main unit, the component supply unit is gripped with the gripping body at the set position, the connector and the connected device are connected, and then the actuator is operated to operate the component supply unit. Power supply is started by moving to the position and detecting that the component supply unit is set at the work position. Therefore, it is possible to connect the connector and the device to be connected without being energized, and to start supplying power after connecting the connector and the device to be connected.

  In addition, when separating the component supply unit from the main body unit, when the component supply unit is moved from the work position toward the set position, the power supply is automatically stopped, and then the component supply unit at the set position.

Thus, since the power supply is automatically stopped, it is possible to prevent the operator from forgetting to turn off the power. In addition, the connection device and the connected device can be disconnected without being energized.

Furthermore, in the component mounting apparatus according to a second aspect, in the invention according to the first aspect, the power supply control unit sets the component supply unit at the working position by the detection unit after the actuator starts operating. When this is detected, the power supply source is controlled to supply power.
As described above, since the detection means detects that the component supply unit is set at the work position after the actuator starts operating, the power supply start condition is used, so that the detection means is present at the work position. By detecting an object other than the supply unit, it is possible to reliably prevent power supply from being erroneously performed.

  According to a third aspect of the present invention, there is provided a component mounting apparatus including a main body portion and a component supply portion that can be attached and detached from a predetermined set position of the main body portion. A component mounting apparatus to be mounted, which is provided in the main body unit, and grips a part of the component supply unit, thereby fixing the component supply unit at a predetermined work position for supplying components, A connector for connecting a power supply line that is provided in the component supply unit and supplies power to the component supply unit; and a connector that is provided in the gripping body and grips the component supply unit; A connected device to be connected; power supply control means for controlling a power supply source so as to perform connection and disconnection between the connected device and the connected device with the power supply stopped; and the set position.

And means for supplying the power supply source so as to supply power when the connection state detecting means detects that the connection device and the connected device are in a connected state after the actuator starts operating. It is characterized by control.

  As a result, when the component supply unit is set on the main body unit, when the component supply unit is gripped by the gripping body at the set position and the connector and the connected device are connected, the power supply is detected after this is detected. Be started. Therefore, it is possible to connect the connector and the device to be connected without being energized, and to start supplying power after connecting the connector and the device to be connected.

  In addition, when separating the component supply unit from the main unit, when the actuator is stopped to move the component supply unit from the working position to the set position, the power supply is automatically stopped, and then the set The connection between the connector and the connected device is released by pulling the component supply unit and the gripping body apart at the position. In this way, since the power supply is automatically stopped, it is possible to prevent the operator from forgetting to turn off the power, and the connection device and the connected device can be disconnected without being energized.

Furthermore, the component mounting apparatus according to a fourth aspect is the invention according to the third aspect, wherein the power source control means connects the connection device and the connected device by the connection state detection means after the operation of the actuator is started. The power supply source is controlled so that power supply is started after a predetermined time has elapsed since the state is detected.
Thereby, when setting a component supply part to a main-body part, a delay time can be provided reliably after an electric power supply is started after connecting a connector and a to-be-connected device. Therefore, the safety at the time of connecting the connector and the device to be connected can be improved.

  Moreover, the component mounting apparatus which concerns on Claim 5 is the invention which concerns on any one of Claims 1-4. WHEREIN: As for the said connector and the said to-be-connected device, one connection port is upward and the other connection port is downward.

  Thus, since the upper surface of the connection port is covered with the cover when the component supply unit is separated from the main body unit, it is possible to prevent foreign matter from dropping into the connection port. Therefore, it is possible to prevent the occurrence of a short circuit or the like due to the connection between the connector and the connected device in a state where the foreign object has dropped and left at the connection port. Furthermore, since the cover is opened and closed according to the attachment and detachment of the component supply unit from the main body unit, when the component supply unit is mounted, the cover can be opened to prevent the cover from interfering with the connector, At the time of separation of the component supply unit, it is possible to reliably prevent foreign matter from falling on the connector by closing the cover.

According to the present invention, since the connection and disconnection of the connector and the connected device are performed in a state where the power supply is stopped, the life of the contact is consumed due to the occurrence of an arc or the like in the connector contact, or chattering at the time of contact It is possible to prevent the occurrence of a circuit failure due to the influence of voltage fluctuation due to the above, and to ensure safety. In addition, since the power supply is automatically started after the connection device and the connected device are connected, the operator does not need to operate the power switch or the like, and the work time of the worker can be shortened.
Thus, a component mounting apparatus with improved workability and reliability can be obtained.

When the raising switch 15 is turned on and the actuator 73 is operated in this inserted state, the movable plate 72 rises, and the upper surface of the movable plate 72 comes into contact with the lower surface of the base 23 of the feeder bank 22. At this time, the positioning pin 72a of the movable plate 72 is inserted into the guide hole 23c of the base 23, and the floating connector 29 and the connector 75 are connected.

When the movable plate 72 is lifted as it is and the feeder bank 22 is lifted along the guide shaft 21b, the positioning pin 23a of the base 23 is inserted into the guide hole 71a of the fixed plate 71, and the base 23 is connected to the fixed plate 71. It is sandwiched between the movable plate 72 and fixed.
Thus, the feeder bank 22 mounted at the set position M1 is a work position for supplying parts by the actuator 73 (here, the upper limit position of the ascending stroke at which the upper surface of the base 23 abuts the lower surface of the fixed plate 71). ). At that time, when the base 23 is gripped by the fixed plate 71 and the movable plate 72 at the set position M1, the floating connector 29 and the connector 75 are automatically connected.

Here, the rising detection sensor 77 detects that the feeder bank 22 is set at the work position. When the feeder bank 22 is set at the work position, the ON signal is detected and the feeder bank 22 is set to work. An OFF signal is output when the position is not set.
In the present embodiment, the feeder bank 22 is automatically turned on after the feeder bank 22 is set in the main body 1A and the floating connector 29 and the connector 75 are connected.

FIG. 4 is a circuit diagram of power control means for turning ON / OFF the feeder bank power.
The feeder bank power ON / OFF control circuit is composed of a 2-input AND circuit 41. The AND circuit 41 inputs the ON / OFF signal of the ascent switch 15 and the ON / OFF signal of the ascent detection sensor 77, and outputs a signal for turning on / off the feeder bank power supply. That is, the feeder bank power supply is turned on when both the signals of the raising switch 15 and the raising detection sensor 77 are ON, and turned off when at least one of the signals is OFF.

  The component supply device 2 corresponds to the component supply unit, the gripping mechanism 7 corresponds to the gripping body, the cable 34 corresponds to the power supply line, the floating connector 29 corresponds to the connector, and the connector 75 corresponds to the connected device. The rise detection sensor 77 corresponds to the detection means, and the AND circuit 41 corresponds to the power supply control means.

(Operation)
Next, the operation of the first embodiment will be described.
In a state where the feeder bank 22 is not set in the component mounting apparatus 1, since the signals from the ascent switch 15 and the ascent detection sensor 77 are both OFF, the feeder bank power supply is OFF. At this time, the upper surface of the connector 75 is covered with the cover 76 to prevent foreign matter or the like from falling on the connector 75.

  In order to set the feeder bank 22 from this state, first, the batch exchanging carriage 2 with the new tape feeder 3 mounted on the feeder bank 22 is inserted into the set position M1 of the component mounting apparatus 1. At this time, the cover 76 on the connector 75 is pushed by inserting the feeder bank 22 to open the cover 76. Then, the feeder bank 22 is inserted to a position where the floating connector 29 is disposed opposite to the connector 75.

  In this state, the worker turns on the raising switch 15 at time t1 in FIG. 5 in order to raise and fix the feeder bank 22. At this time t1, the signal of the ascending switch 15 is turned ON, but the feeder bank 22 is not ascended / fixed and the ascending detection sensor 77 does not detect the feeder bank 22, so the signal of the ascending detection sensor 77 is OFF. To maintain. Therefore, at time t1, the feeder bank power supply is also kept off.

  FIG. 6 is a schematic diagram when the raising switch 15 is turned on. As shown in FIG. 6, when the raising switch 15 is turned on, the movable plate 72 is raised, the positioning pin 72a of the movable plate 72 is inserted into the guide hole 23c of the base 23, and the floating connector 29 and the connector 75 are connected. Connected. This connector connection time is t2. At this time, as shown in FIG. 5, the floating connector 29 and the connector 75 are in contact with each other, but the signal of the rise detection sensor 77 is maintained in the OFF state, so that the feeder bank power supply is also maintained in the OFF state.

  Thereafter, when the movable plate 72 and the feeder bank 22 are lifted while the floating connector 29 and the connector 75 are connected, the positioning pins 23a of the base 23 are inserted into the guide holes 71a of the fixed plate 71 as shown in FIG. The base 23 is inserted and fixed between the fixed plate 71 and the movable plate 72. At this time, the rise detection sensor 77 detects that the feeder bank 22 has been raised and fixed. This time is assumed to be t3. At time t3, the signal from the rising switch 15 and the signal from the rising detection sensor 77 are both turned on, so that the feeder bank power supply is switched to the ON state as shown in FIG.

  In this way, the feeder bank power supply is turned on under the condition that both the raising switch 15 and the raising detection sensor 77 are on. Therefore, the movable plate 72 can be raised with the feeder bank power turned off, and the connector can be connected without being energized. Further, when the feeder bank 22 is raised, the connector is connected while the feeder bank 22 is being raised, and thereafter, the rise detection sensor 77 is turned on near the upper limit of the raising stroke and the feeder bank power is turned on. Can be turned on.

  At the time of lowering, the operator lowers the feeder bank 22 by turning off the ascent switch 15. In this case, as shown in FIG. 8, when the raising switch 15 is turned off at time t11, the feeder bank power supply is turned off at the same time. Thereafter, as the movable plate 72 descends, the feeder bank 22 also descends, and the rise detection sensor 77 is turned off at time t12. When the movable plate 72 is further lowered, the floating connector 29 and the connector 75 are pulled off.

In this way, at the time of lowering, the feeder bank power supply can be turned off at the same time as the raising switch 15 is turned off, so that the connector can be pulled off without being energized.
Further, when the collective exchanging cart 2 is pulled out from the set position M1 of the main body 1A in a state where the floating connector 29 and the connector 75 are detached, the pressing force to the cover 76 of the feeder bank 22 is released, and FIG. As shown, the cover 76 is returned to a position that covers the upper surface of the original connector 75 by the biasing member 76a.

(effect)
As described above, in the first embodiment, since connector connection and disconnection can be performed without energization, it is possible to prevent an arc or the like from occurring at the connector contact. In addition, since the circuit is not affected by voltage fluctuation due to chattering at the time of contact, stable operation can be provided.
In addition, since the power is automatically supplied to the feeder bank when the feeder bank is raised and fixed, it is not necessary for the operator to operate the power switch, and the working time can be shortened.
Further, since the power supply to the feeder bank is automatically stopped when the feeder bank is lowered, it is possible to prevent the operator from forgetting to turn off the power and to ensure safety.

In addition, since the cover is provided on the upward-structured connector provided on the main body side, it is possible to prevent foreign matter from falling on the connector. Therefore, it is possible to prevent a short circuit or the like from occurring due to the connector connection in a state in which the foreign matter is falling, and to ensure safety.
Furthermore, since this cover is configured to automatically open and close when the batch exchange cart is attached / detached, the cover can be opened to prevent the cover from interfering with connector connection when the batch exchange cart is installed. When separating the batch exchanging cart, the cover can be closed to reliably prevent foreign matter from falling on the connector.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.
In the second embodiment, the feeder bank power supply is ON / OFF controlled using the signal of the ascending switch 15 and the signal of the ascending detection sensor 77 in the first embodiment, whereas the ascending switch 15 and the connector connection state, the feeder bank power supply is ON / OFF controlled.

(Constitution)
FIG. 10 is a diagram schematically illustrating an arrangement relationship between the feeder bank 22 and the gripping mechanism 7 in the second embodiment.
As shown in FIG. 10, the component mounting apparatus 1 according to the present embodiment has a configuration in which the rise detection sensor 77 shown in FIG. 3 is deleted.
In the present embodiment, as in the first embodiment described above, after the feeder bank 22 is set in the main body 1A and the floating connector 29 and the connector 75 are connected, the feeder bank 22 is automatically turned on. Is configured to do.
FIG. 11 is a circuit diagram of power control means for performing ON / OFF control of feeder bank power.

The feeder bank power ON / OFF control circuit includes an AND circuit 42, a delay circuit 43, and a feeder bank presence / absence detection circuit 44.
The AND circuit 42 receives the ON / OFF signal of the rising switch 15 and the output signal of the delay circuit 43. The delay circuit 43 is a circuit that outputs a signal from the feeder bank presence / absence detection circuit 44 with a predetermined delay time. Here, the feeder bank presence / absence detection circuit 44 outputs a signal that is ON when the floating connector 29 and the connector 75 are connected, and is OFF when the floating connector 29 and the connector 75 are not connected. Is a circuit that outputs a signal.

That is, the feeder bank power supply is turned on when the delay time elapses after the signal of the feeder bank presence / absence detection circuit 44 is turned on when the raising switch 15 is turned on.
The AND circuit 42 and the delay circuit 43 correspond to power supply control means, and the feeder bank presence / absence detection circuit 44 corresponds to connection state detection means.

(Operation)
Next, the operation of the second embodiment will be described.
When the feeder bank 22 is set from the state in which the feeder bank 22 is not set in the component mounting apparatus 1, first, the batch exchanging carriage 2 having the new tape feeder 3 mounted on the feeder bank 22 is first replaced with the component mounting apparatus 1. Is inserted into the set position M1. At this time, the cover 76 is pushed by inserting the feeder bank 22, and the cover 76 is opened. Then, the feeder bank 22 is inserted to a position where the floating connector 29 is disposed opposite to the connector 75. In this state, the operator turns on the raising switch 15 in order to raise and fix the feeder bank 22.

  At this time, as shown in FIG. 12, since the floating connector 29 and the connector 75 are not connected, the signal of the feeder bank presence / absence detection circuit 44 (feeder bank presence / absence signal) is OFF indicating that the feeder bank 22 is not present. It is in a state. Therefore, when the time when the up switch 15 is turned on is t21, the feeder bank power supply is kept OFF at time t21 as shown in FIG.

  Thereafter, when the movable plate 72 moves up and the floating connector 29 and the connector 75 are connected at time t22, the feeder bank presence / absence signal is switched to an ON state indicating that the feeder bank 22 is present. However, at this time, since the output signal of the feeder bank presence / absence detection circuit 44 is input to the AND circuit 42 via the delay circuit 43, the feeder bank power supply maintains the OFF state at time t22.

Then, at time t23 when a predetermined delay time has elapsed from time t22, the output signal of the delay circuit 43 is turned on, and the feeder bank power supply is switched to the ON state. A state diagram at this time is shown in FIG.
Thus, at the time of ascent, the feeder bank presence / absence signal is turned ON by connecting the connector in the middle of the ascent of the feeder bank 22. Since the feeder bank presence / absence signal is input to the AND circuit 42 via the delay circuit 43, the feeder bank power supply is turned on with a delay after the feeder bank presence / absence signal is turned on. Therefore, the connector can be connected without being energized, and the power can be supplied after the connector is connected.

At the time of lowering, the operator lowers the feeder bank 22 by turning off the ascent switch 15. In this case, as shown in FIG. 15, when the raising switch 15 is turned off at time t31, the feeder bank power supply is turned off at the same time. The state diagram at this time is as shown in FIG. Thereafter, as the movable plate 72 descends, the feeder bank 22 also descends, and the floating connector 29 and the connector 75 are detached at time t32. At the same time, the feeder bank presence / absence signal is turned off.
In this way, at the time of lowering, the feeder bank power supply can be turned off at the same time as the raising switch 15 is turned off, so that the connector can be pulled off without being energized.

(effect)
As described above, in the second embodiment, as in the first embodiment described above, the connector can be connected and disconnected without being energized. In addition, power can be automatically supplied to the feeder bank after the connector is connected.
At this time, since the signal of the rise switch and the signal of the feeder bank presence / absence detection circuit for detecting the connector connection state are used for ON / OFF control of the feeder bank power supply, the rise detection sensor as in the first embodiment described above is provided. There is no need. Therefore, the cost can be reduced, and the degree of freedom in design can be improved.

(Modification)
In the first embodiment, the case where the ON / OFF control of the feeder bank power supply is performed using the signal of the ascent switch 15 and the signal of the ascent detection sensor 77 has been described, but only the signal of the ascent detection sensor 77 is described. It is also possible to perform ON / OFF control of the feeder bank power supply using. At this time, the feeder bank power supply may be turned on when the rise detection sensor 77 is in the ON state, and the feeder bank power supply may be turned off when the rise detection sensor 77 is in the OFF state.

  Also in this case, when the feeder bank is raised, after the floating connector 29 and the connector 75 are connected in the middle of raising, the feeder bank power is turned on when the feeder bank 22 is further raised and fixed at the work position. Become. Also, when the feeder bank is lowered, the feeder bank power is turned off when the feeder bank 22 is lowered and removed from the working position. Thereafter, the feeder bank 22 is further lowered, and then the rotating connector 29 and the connector 75 are pulled out. Will be. In this way, the connector can be inserted and removed without being energized.

  In the second embodiment, the case where the output signal of the feeder bank presence / absence detection circuit 44 is input to the AND circuit 42 via the delay circuit 43 has been described. However, the delay circuit 43 may be omitted. In this case, after the connector is connected and the feeder bank presence / absence signal is turned ON, the feeder bank power supply is turned ON with a delay due to the delay of the related circuit. Therefore, it is always possible to energize after a connector is connected. However, it goes without saying that it is possible to obtain a certain effect by intentionally providing the delay circuit 42 for delaying the feeder bank presence / absence signal.

  Further, in each of the above embodiments, the case has been described where the movable cover 76 that protects the connector connection port from foreign matter is installed above the connection port of the connector 75. However, the connection port of the floating connector 29 faces upward and the connector 75 is connected. When the connection port is disposed downward, a movable cover having the same function as the cover 76 is installed above the connection port of the floating connector 29.
