  In order to install each tape feeder 9 in the component mounting apparatus 1, the tape feeder replacement carriage 20 having a plurality of tape feeders 9 mounted on the feeder base 28 is moved by operating the handle 21, so that the base of the component mounting apparatus 1 is installed. However, when the tape feeder replacement carriage 20 is joined to the base 2, a carriage-side connector 30 (first connector) provided on the front surface of the base portion 40 is provided on the base 2. The mounting device side connector 15 (second connector) thus formed is fitted and connected in the horizontal direction.

  The cart-side connector 30 is a floating connector that can move in a plane perpendicular to the fitting direction with the mounting device-side connector 15. The mounting device-side connector 15 receives the cart-side connector 30 to assist the fitting. A guide 15a is provided (FIG. 3). For this reason, even when the connectors 30 and 15 are slightly misaligned when the tape feeder replacement carriage 20 is positioned with respect to the base 2, when the tape feeder replacement carriage 20 is coupled to the base 2. Since the cart side connector 30 is drawn into the mounting apparatus side connector 15 side by the fitting guide 15a, both the connectors 30 and 15 can be fitted without any trouble.

The component mounting apparatus 1 incorporates an air pressure generating unit 16 and a power supply unit 17, and these air pressure generating unit 16 and power supply unit 17 are connected via a pipe 18 and a wiring 19 disposed in the component mounting apparatus 1. The mounting device side connector 15 is connected. For this reason, the carriage side connector 30 and the mounting apparatus side connector 15 are fitted, so that the air pressure generating unit 16 and the power supply unit 17 on the component mounting apparatus 1 side can be used on the tape feeder replacement carriage 20 side. become. Specifically, the pneumatic actuator 45 can be used with the pneumatic generation unit 16 as an pneumatic source, and the control device 48 can be used with the power supply unit 17 as a power source.

  In FIG. 4, the pneumatic actuator 45 includes a cap side cylinder chamber 45b and a head side cylinder chamber 45c. When pressurized air is supplied to the cap side cylinder chamber 45b, the piston rod 45a is advanced to move the movable blade 44 to the fixed blade. When the compressed air is supplied to the head-side cylinder chamber 45c, the piston rod 45a is moved backward to move the movable blade 44 to the fixed blade 41 (closed operation of the two cutting blades, arrow A in FIG. 4). (The opening operation of the two cutting blades, arrow B in FIG. 4).

  In FIG. 4, the pneumatic circuit 47 includes a first pipe 51, a second pipe 52, and a third pipe 53 in addition to the control valve 49 and the check valve 50. The control valve 49 is a two-position two-way electromagnetic pilot valve. When no spool drive signal is output from the control device 48, the spool (not shown) is moved to the normal position (position shown in FIG. 4) by the action of the return spring 49s. To position. On the other hand, when the spool drive signal is output from the control device 48, the spool moves against the urging force of the return spring 49s by the pilot pressure generated in response to the spool drive signal, and is positioned at the switching position.

  The first pipe line 51 is a pipe line connecting the truck side connector 30 and “the pressure port 49p of the control valve 49”, and the second pipe line 52 is “the first cylinder port 49a of the control valve 49” and “ This is a pipe line connecting between the first ports 46a connected to the cap side cylinder chamber 45b of the pneumatic actuator 45. The third pipe 53 is a pipe connecting between the “second cylinder port 49b of the control valve 49” and the “second port 46b connected to the head side cylinder chamber 45c of the pneumatic actuator 45”.

  The check valve 50 is interposed in the first pipe line 51. When the pressure on the cart side connector 30 side is higher than the pressure on the pneumatic actuator 45 side, the first pipe line 51 is opened and the cart side connector 30 side is opened. When the pressure becomes lower than the pressure on the pneumatic actuator 45 side, the first pipe 51 is closed.

  In a state where the spool of the control valve 49 is located at the normal position, the pressure port 49p and the first cylinder port 49a communicate with each other, and the second cylinder port 49b and the first tank port 49c communicate with each other. At this time, the compressed air supplied from the pneumatic pressure generating unit 16 via the cart side connector 30 is supplied from the first pipe 51 → the control valve 49 (pressure port 49p → first cylinder port 49a) → second pipe 52 → empty. The piston rod 45a is advanced by being supplied to the cap side cylinder chamber 45b of the pressure actuator 45, and the two cutting blades are closed. On the other hand, when the spool of the control valve 49 is located at the switching position, the pressure port 49p and the second cylinder port 49b communicate with each other, and the first cylinder port 49a and the second tank port 49d communicate with each other. At this time, the pressure air supplied from the pneumatic pressure generating unit 16 via the cart side connector 30 is the first pipe 51 → the control valve 49 (pressure port 49p → second cylinder port 49b) → the third pipe 53 → empty. The piston rod 45a is retracted by being supplied to the head side cylinder chamber 45c of the pressure actuator 45, and the two cutting blades are opened.

The tape feeder 9 feeds out the tape 11 and supplies the component P to the pickup position during the component mounting process by the component mounting apparatus 1, while discharging the empty tape 11 a after supplying the component to the lower side of the feeder base 28. The empty tape 11a after the component supply discharged from the tape feeder 9 is directly erected on the upper surface of the base portion 40 of the tape cutting device 23 and does not go through the member on the component mounting device 1 side, and opens upward. It is guided by the guide member 54 and enters the base portion 40 through the upper opening 40a and is sent between the fixed blade 41 and the movable blade 44 (see also FIG. 4).

  Here, while the tape 11 is fed out from the tape feeder 9 and the component P is supplied to the component mounting apparatus 1, the control device 48 controls the control valve 49 of the pneumatic circuit 47 to control the two cutting blades. Since the closing operation and the opening operation are repeatedly performed, and the tape feeder 9 feeds the tape 11 to the outside of the tape feeder 9 (below the feeder base 28) in an intermittent operation, the tape feeder 9 is discharged from the tape feeder 9. The empty tape 11a that is guided by the tape guide member 54 and enters the base portion 40 through the upper opening 40a is cut by the tape cutting device 23 every time the fixed length advances, and the cut empty tape 11a having the fixed length is It is discharged from the lower opening 40 b provided at the lower part of the base part 40 to the outside of the base part 40 and is collected by the tape collecting part 24.

  On the other hand, by separating the tape feeder replacement carriage 20 from the component mounting apparatus 1 from the state in which the tape feeder replacement carriage 20 is coupled to the component mounting apparatus 1 in this way, each tape feeder 9 is connected to the component mounting apparatus 1. Can be removed from. At this time, since the cart-side connector 30 is separated from the mounting device-side connector 15, the tape feeder replacement cart 20 can no longer use the air pressure generating unit 16 and the power supply unit 17 provided on the component mounting device 1 side. However, when the cart side connector 30 is separated from the mounting device side connector 15, the pipe line (first pipe line 51) that has been connected between the air pressure generating unit 16 and the control valve 49 is released to the atmosphere. Since electricity is not supplied to the control device 48 and the control valve 49 is not controlled, the spool of the control valve 49 is positioned at the normal position by the action of the return spring 49s.

In this way, the pipe line (first pipe line 51) between the air pressure generation unit 16 that is the air pressure source and the control valve 49 is opened to the atmosphere, and the supply of compressed air to the air pressure actuator 45 is stopped. When the spool is located at the normal position, the check valve 50 interposed in the first pipe 51 closes the first pipe 51, so that pressure remains between the pneumatic actuator 45 and the check valve 50. The control valve 49 communicates the first pipe line 51 with the first port 46a of the pneumatic actuator 45 and also communicates the second port 46b of the pneumatic actuator 45 with the first tank port 49c so as to open the atmosphere. The pressure remaining between the pressure actuator 45 and the check valve 50 acts on the cap-side cylinder chamber 45b from the first port 46a of the pneumatic actuator 45. As a result, the pneumatic actuator 45 operates to advance the piston rod 45a, so that the movable blade 44 moves to the fixed blade 41 side and the two cutting blades (the fixed blade 41 and the movable blade 44) are closed. Become.

  As described above, the tape cutting device 23 included in the tape feeder replacement carriage 20 according to the present embodiment closes the two cutting blades when the pneumatic supply from the pneumatic generation unit 16 to the pneumatic actuator 45 is stopped. Since the closing blade means is provided, it is possible to prevent foreign matter from entering between the two cutting blades (the fixed blade 41 and the movable blade 44) when the tape cutting device 23 is not used, and the tape cutting device 23 can be prevented from malfunctioning. There is no risk of it happening.

Here, the closing blade means includes a pneumatic actuator 45, a control valve 49, and a check valve 50 interposed in a first pipe 51 that is a pipe between the pneumatic generator 16 and the control valve 49. Thus, when the first pipe 51 is opened to the atmosphere and the supply of compressed air from the pneumatic generation unit 16 to the pneumatic actuator 45 is stopped, the control valve 49 communicates the first pipe 51 with the pneumatic actuator 45. by the check valve 50 closes the first conduit 51, thereby pneumatic actuator 45 and actuated so with two cutting blades residual pressure pneumatic actuator 45 between the check valve 50 (fixed It refers to a mechanism for closing the blade 41 and the movable blade 44).

  Further, the tape feeder replacement carriage 20 in the present embodiment is provided with a tape cutting device 23 in the vehicle body portion 22, and the empty tape 11 a discharged from each tape feeder 9 does not pass through the component mounting device 1. Since the tape 11 is sent directly to the tape cutting device 23 and cut, the work of introducing the tape 11 drawn from each tape feeder 9 into the tape cutting device 23 is performed before the tape feeder 9 is installed in the component mounting device 1. In other words, the tape feeder replacement carriage 20 can be performed in advance before being coupled to the component mounting apparatus 1, and the tape feeder replacement can be performed without removing the empty tape 11 a extending from each tape feeder 9 from the tape cutting apparatus 23. The carriage 20 can be separated from the component mounting apparatus 1 and each tape feeder 9 can be removed from the component mounting apparatus 1. Kill. For this reason, the work time required for installation and removal of the tape feeder 9 can be shortened, and the component mounting throughput by the component mounting apparatus 1 can be improved accordingly.

(Embodiment 2)
FIG. 5 is an explanatory diagram of a pneumatic circuit of a tape feeder replacement carriage provided in the component mounting apparatus according to Embodiment 2 of the present invention. The difference between the pneumatic circuit 47a of the second embodiment and the pneumatic circuit 47 of the first embodiment is that a check valve 50 is provided in the first pipe 51 as in the pneumatic circuit 47 of the first embodiment. The biasing spring 55 that biases one of the two cutting blades toward the other (here, the movable blade 44 approaches the fixed blade 41) is not provided.

  In FIG. 5, when the cart side connector 30 is separated from the mounting device side connector 15, the first pipe line 51 is opened to the atmosphere, and the spool of the control valve 49 is positioned at the normal position by the action of the return spring 49s. At this time, the control valve 49 opens the first port 46 a of the pneumatic actuator 45 to the atmosphere via the control valve 49 and the first pipe 51, and the second port 46 b of the pneumatic actuator 45 connects to the first tank port of the control valve 49. Since the air is released from 49c, the piston rod 45a of the pneumatic actuator 45 can be freely moved by an external force. That is, the two cutting blades can be freely opened and closed by an external force. For this reason, the movable blade 44 is urged by the urging spring 55 and moves to the fixed blade 41 side, and the two cutting blades composed of the fixed blade 41 and the movable blade 44 are closed.

  Also in the configuration of the second embodiment, the same effect as that of the first embodiment described above can be obtained. In the case of the second embodiment, the closing blade means that the pneumatic actuator 45, the control valve 49, and one of the two cutting blades are moved closer to the other (here, the movable blade 44 is moved closer to the fixed blade 41). When the pressure supply from the air pressure generating unit 16 to the air pressure actuator 45 is stopped when the first pipe 51 is opened to the atmosphere, the control valve 49 is air-operated. Each port (first port 46a and second port 46b) of the actuator 45 is opened to the atmosphere so that the two cutting blades can be freely opened and closed, and the urging spring 55 causes one of the cutting blades (movable blade 44) to move. It refers to a mechanism that closes the two cutting blades by biasing them closer to the other cutting blade (fixed blade 41).

(Embodiment 3)
In the third embodiment, the urging spring 55 provided in the second embodiment is added to the configuration of the first embodiment. In such a configuration, as in the case of the first embodiment, the inside of the pipe line (first pipe 51) between the air pressure generation unit 16 and the control valve 49 is opened to the atmosphere, and the air pressure generation unit 16 is emptied. When the pneumatic supply to the pressure actuator 45 is stopped, not only the two cutting blades (the fixed blade 41 and the movable blade 44) are closed, but then the pressure in the cap-side cylinder chamber 45b of the pneumatic actuator 45 is temporarily assumed. Even when the check valve 50 is reduced to the atmospheric pressure level and the check valve 50 does not perform the closing function in the first pipe 51, the two cutting blades are reliably closed by the action of the biasing spring 55. It can be kept in the state.

Although the embodiment of the present invention has been described so far, the scope of the present invention is not limited to that shown in the above-described embodiment. For example, in the above-described embodiment, the pneumatic actuator 45 is a pneumatic cylinder. However, this is not limited to the pneumatic cylinder, and the empty tape 11 a discharged from the tape feeder 9 is controlled by the control valve 49. Operates in response to pressure supply from the pressure source (pneumatic pressure generating unit 16 in the above example), thereby opening and closing the two cutting blades (in the above example, the fixed blade 41 and the movable blade 44) and cutting. Any other pneumatic actuator (for example, a pneumatic motor) may be used. Furthermore, it is not limited to pneumatic pressure, and other general actuators such as those using an electric motor may be used.

  In the above-described embodiment, one of the two cutting blades provided in the tape cutting device 23 is a fixed blade 41 fixed to the base portion 40, and the other is a movable blade 44 provided movably with respect to the fixed blade 41. However, the two cutting blades are not limited to one of which is a fixed blade and the other is a movable blade, and both of them move with each other to open and close (both are movable blades). There may be.

  When not in use, foreign matter can be prevented from entering between the two cutting blades.
