This is to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art. The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter recited in the claims.

[Embodiment 1]
First, an example of a component mounting apparatus according to Embodiment 1 will be described.

FIG. 1 is a plan view schematically showing a schematic configuration of a component mounting device 11 according to the first embodiment. The component mounting device 11 has a function of mounting components supplied from a plurality of component supply devices onto the board 13. In each of the following embodiments, a tape feeder 17 that supplies components by intermittently feeding a carrier tape 15 (see FIG. 2), which is a tape member in which components are encapsulated, is used as a component supply device.

The component mounting device 11 has a pedestal 19 . A substrate conveyor 21 is arranged in the center of the pedestal 19 along the X direction. The board conveyor 21 transports the work target board 13 received from the upstream device in the X direction and positions it at a component mounting position. Component supply sections 23 and 25 are arranged on both sides of the substrate conveyor 21, respectively.

A cart 27 that can mount a plurality of tape feeders 17 on the component mounting device 11 at once is set in each of the component supply units 23 and 25 arranged on the lower side and the upper side of FIG. At least one tape feeder 17, which is a plurality of component supply devices, is mounted on the trolley 27 together with a corresponding reel 29.

A Y-axis moving table 31 is arranged along the Y direction at one end of the upper surface of the pedestal 19 on the X direction side. The Y-axis moving table 31 is held by a frame body. An X-axis moving beam 33 is mounted on the Y-axis moving table 31 so as to be movable in the Y direction. A mounting head 35 is attached to the X-axis moving beam 33 so as to be movable in the X direction. The Y-axis moving table 31 and the X-axis moving beam 33 constitute a head moving mechanism 37 that moves the mounting head 35.

FIG. 2 is a front view of the component mounting device 11 shown in FIG. 1 with the upper side omitted. By driving the head moving mechanism 37, the mounting head 35 moves in the X direction and the Y direction, respectively. As a result, the mounting head 35 uses the nozzle 39 provided at the lower end to take out the components from the tape feeders 17 disposed in each of the component supply sections 23 and 25, and mounts the components onto the substrate 13 positioned on the substrate conveyor 21. do.

A board recognition camera 41 that moves integrally with the mounting head 35 is provided on the lower surface side of the X-axis moving beam 33. By moving the mounting head 35 and positioning the board recognition camera 41 above the board 13, the board recognition camera 41 images the top surface of the board 13.

Further, a component recognition camera 43 is arranged between the board conveyor 21 and each of the component supply sections 23 and 25. By positioning the mounting head 35 that has taken out components from each of the component supply units 23 and 25 above the component recognition camera 43, the component recognition camera 43 images the state of the component held by the mounting head 35.

The operations of each of the above-mentioned parts are controlled by a control section 45 of the main body provided on the pedestal 19. The top and side surfaces of the head moving mechanism 37 and the mounting head 35 are covered by a cover member 47 (see FIG. 2). Display panels 49 for operation are arranged on both sides of the cover member 47. When the operator performs operation input via the display panel 49, operation commands to each part of the component mounting apparatus 11 are input.

Next, the component supply section 23 will be described as a representative example among the component supply sections 23 and 25 having substantially the same configuration. In the component supply section 23 , the cart 27 is mechanically fixed to the pedestal 19 by fixing means provided on the pedestal 19 . The trolley 27 is electrically connected to the main body within the frame via a trolley connector. The truck connector also operates as a truck presence/absence detection switch 51. The cart 27 holds a plurality of reels 29 in which carrier tapes 15 with parts sealed therein are wound and housed. The carrier tape 15 pulled out from the reel 29 is taken into the tape feeder 17, is intermittently fed inside the tape feeder 17, and is conveyed to a take-out position by the mounting head 35. During this tape feeding process, the cover tape is peeled off from the carrier tape 15. The mounting head 35 takes out the component from the carrier tape 15 after the tape has been peeled off.

The used carrier tape after tape peeling is guided by a tape guide 53 opened at the front end of the tape feeder 17 and sent to a cutting section 55 provided below, where it is cut into strips. The cutting section 55 is also called a tape cutter. The waste tape 57, which is the used carrier tape that has been cut into strips, is guided downward through a chute portion 59 that constitutes a tape discharge path, and is collected by a collection portion 61 provided at the bottom of the cart 27. Ru.

Next, the configuration and operation of the cutting section 55 will be explained.

A cutting section 55 is provided below the tape feeder 17. The cutting section 55 has a function of cutting the used carrier tape discharged from the tape feeder 17.

FIG. 3 is an enlarged view of the main part of FIG. The cutting section 55 has a configuration in which a fixed blade 65 fixed inside the housing section 63 and a movable blade 69 that moves forward and backward with respect to the fixed blade 65 by a cylinder 67 that is a driving section are arranged facing each other. These fixed blade 65 and movable blade 69 constitute a tape cutter as an example of a cutting section. The chute section 59 is removably fixed to, for example, the housing section 63 of the cutting section 55 by a plurality of (eg, two) fixing screws 71 (see FIG. 4). Note that the chute section 59 may be fixed to the pedestal 19 instead of the housing section 63. A tape guide 53 that guides the used carrier tape discharged from the tape feeder 17 of the component supply section 23 is inserted into the housing section 63 . An opening communicating with the chute section 59 is provided on the bottom surface of the housing section 63.

In the cutting section 55, a fixed blade 65 and a movable blade 69 are respectively arranged near an opening provided on the bottom surface of the housing section 63. The opening of this housing section 63 is covered by the chute section 59. In other words, each of the fixed blade 65 and the movable blade 69 is inaccessible and safely covered when the chute 59 is attached, but cannot be accessed from the opening when the chute 59 is removed. It becomes possible. Therefore, during maintenance of the component mounting device 11, each of the fixed blade 65 and the movable blade 69 will be exposed (exposed), which may reduce the safety of workers.

When components are supplied by the tape feeder 17 in the component supply section 23 , the used carrier tape from which the components have been taken out is guided into the casing section 63 by the tape guide 53 . When the cylinder 67 is driven in this state to cause the movable blade 69 to reciprocate, the used carrier tape becomes waste tape 57 cut into strips. The waste tape 57 then falls into the chute section 59 and is thrown into a collection section 61 provided on the cart 27 by the chute section 59.

FIG. 4 is a side view of FIG. 3. A blocking portion 73 is provided on the side surface of the chute portion 59 . The cutoff section 73 cuts off the supply of power to the drive section. In the first embodiment, the driving section that is shut off by the shutoff section 73 is the cylinder 67 that is driven by fluid (air). The cutoff portion 73 is a connector for piping to which air is supplied.

FIG. 5 is a perspective view of the blocking section 73 in the air supply state. The connector has a first connector and a second connector connected to the first connector.

In the first embodiment, the first connecting portion is the nipple 77 on the male side of the one-touch coupler 75. The second connecting portion becomes a socket 79 on the female side of the one-touch coupler 75. The connected state of the one-touch coupler 75 is maintained by a slidable sleeve 81 provided in the socket 79. The nipple 77 is fixed to the chute portion 59 by a chute side bracket 83. The socket 79 is fixed to the pedestal 19 by a pedestal side bracket 85.

The nipple 77 is fixed to the chute side bracket 83 in a sliding manner so that it can slide in the direction of attachment and detachment of the chute portion 59 (Y direction). Thereby, each of the nipples 77 fixed to the chute side bracket 83 can be independently disconnected from the socket 79.

The socket 79 is fixed to the gantry side bracket 85 in a floating manner so that it can be displaced in a direction perpendicular to the attachment/detachment direction (direction along the XZ plane). This allows each socket 79 to be individually aligned (aligned) with respect to the plurality of nipples 77 when the chute portion 59 is attached.

FIG. 6 is a pneumatic circuit diagram of the cutoff section 73 in the air supply state. A piston 87 is built into the cylinder 67, which is a driving section. In the cylinder 67, main air is alternately supplied to two chambers sandwiching the piston 87 by a first pneumatic pipe 89 and a second pneumatic pipe 91 from a pneumatic source. The cylinder 67 drives a piston rod 93 connected to the piston 87 forward and backward by alternately supplying main air to the two empty chambers. A movable blade 69 is fixed to this piston rod 93.

Two pneumatic circuits, the first pneumatic piping 89 and the second pneumatic piping 91 connected to the pneumatic source, bypass the chute section 59 from the pedestal 19 and return to the pedestal 19 again. Therefore, four one-touch couplers 75 are arranged between the pedestal 19 and the chute section 59. Two of the four nipples 77 attached to the chute portion 59 are connected to each other by a connecting pipe 95 in the same pneumatic circuit. In the case of the four one-touch couplers 75 shown in FIG. 5, air from a pneumatic source enters the upper two, and air is sent to the cylinder 67 from the lower two.

A third pneumatic pipe 97 and a fourth pneumatic pipe 99 are connected to the sockets 79 of the two lower one-touch couplers 75 . The third pneumatic pipe 97 and the fourth pneumatic pipe 99 are connected to each of the two empty chambers of the cylinder 67 that sandwich the piston 87 therebetween. Thereby, main air is alternately supplied to the two empty chambers of the cylinder 67 from the two pneumatic circuits from the pneumatic source.

FIG. 7 is a perspective view of the blocking section 73 in the air blocking state. In the one-touch coupler 75, when the chute portion 59 is removed, the nipple 77 comes off from the socket 79, and the supply of air is cut off. The one-touch coupler 75 disconnects the nipple 77 fixed to the end of one pipe to be attached or detached from the socket 79 fixed to the end of the other pipe, thereby interrupting the pipe line. At the time of removal, the nipple 77 and the socket 79 can be removed by sliding the sleeve 81 against the biasing force of the sleeve spring.

FIG. 8 is a pneumatic circuit diagram of the cutoff section 73 in the air cutoff state. In the socket 79 from which the nipple 77 has been removed, the end of the conduit is automatically closed by a built-in valve. Therefore, when the nipple 77 is removed, the four sockets 79 fixed to the frame side bracket 85 are connected to the first pneumatic pipe 89 and the second pneumatic pipe 91 connected to the pneumatic source, and to the cylinder 67. The third pneumatic pipe 97 and the fourth pneumatic pipe 99 that are connected are cut off at the cutoff portion 73 . On the other hand, the nipple 77 and the connecting pipe 95 fixed to the chute portion 59 are exposed to the atmosphere.

In addition, in the cutoff part 73, each one-touch coupler 75 can be maintained in a connected state with one touch by simply fitting the nipple 77 and the socket 79 together. When the one-touch coupler 75 is in the connected state, the valve of the socket 79 is opened, and the two pipes are in communication with each other and held.

FIG. 9 is a rear view showing the back side of FIG. 3 together with the trolley 27. The pedestal 19 has trolley connection parts on both sides. The cart connection portion connects a cart 27 that can accommodate a reel 29 for supplying the carrier tape 15 to the tape feeder 17. The truck connection portion connects the truck 27 to the pedestal 19 by fitting the connection end provided on the truck 27 . A truck presence/absence detection switch 51 is provided on the side surface of the pedestal 19 to detect that the truck 27 is connected to the truck connection portion. The above-mentioned cart presence/absence detection switch 51 is used as the cart presence/absence detection switch 51 . This truck presence/absence detection switch 51 constitutes a second detection section.

FIG. 10 is an enlarged view of the main part of FIG. For example, a drawer connector can be used as the trolley presence/absence detection switch 51. In the drawer connector, when the trolley 27 enters the trolley connection part, the male and female connector housings are fitted together, the terminals provided inside each housing are connected, and it is detected that the trolley 27 is connected. be done. This detection signal is transmitted to the control section 45. The control unit 45 controls the operation of the movable blade 69 in the cutting unit 55 based on this detection result.

In the first embodiment, the truck presence/absence detection switch 51 permits the operation of the movable blade 69 in the cutting section 55 when a truck is detected. In other words, when the cart 27 is removed from the pedestal 19, the movable blade 69 becomes inoperable. The cutting section 55 is controlled by the truck presence/absence detection switch 51 by a cutter operation control valve, which will be described later, which is interposed between the pneumatic source and the cylinder 67.

Next, an example of the hardware configuration of the component mounting device 11 will be explained.

FIG. 11 is a block diagram showing an example of the hardware configuration in the component mounting apparatus 11. The control unit 45 is configured using a processor such as a CPU (Central Processing Unit) or an FPGA (Field Programmable Gate Array), and controls the operation of each part of the component mounting apparatus 11 and inputs and outputs data between each part. Control. The control unit 45 includes a mounting processing unit 101, a recognition processing unit 103, a cutting processing unit 105, and a display processing unit 107 as internal processing functions. The mounting processing section 101 controls the operations of the substrate conveyor 21 , the mounting head 35 , the head moving mechanism 37 , and the component supply sections 23 and 25 by controlling the mechanism driving section 109 . As a result, a component mounting operation is performed in which components taken out from the component supply section 23 and the component supply section 25 are mounted on the board 13 that is positioned and held on the board conveyor 21.

In this component mounting work, the recognition processing unit 103 performs recognition processing on the imaging results obtained by the component recognition camera 43 and the board recognition camera 41. That is, the position of the board 13 is recognized by performing recognition processing on the image taken by the board recognition camera 41. In addition, by performing recognition processing on the image taken by the component recognition camera 43, identification and positional deviation of the component held by the mounting head 35 are detected. When mounting components using the mounting head 35, the head moving mechanism 37 is controlled taking these recognition results into account.

The cutting processing unit 105 controls the cutting operation by the cutter by controlling the cylinder 67. In this control, the operation of the cutter, which is the cutting part 55, is controlled based on the detection result of the truck presence/absence detection switch 51, which is the second detection part. That is, when the truck presence/absence detection switch 51 detects the connection of the truck 27, the cutter operation is permitted. This prevents the above-mentioned inconvenience caused by the cutter operating when the cart 27 is removed from the pedestal 19. The display processing unit 107 displays on the display panel 49 that the cart 27 is removed from the pedestal 19 .

Next, the operation of the component mounting device 11 according to the first embodiment will be explained.

In the component mounting apparatus 11 according to the first embodiment, the carrier tape 15 pulled out from the reel 29 is taken into the tape feeder 17. The carrier tape 15 is intermittently fed inside the tape feeder 17 and is conveyed to a take-out position by the mounting head 35. During this tape feeding process, the cover tape is peeled off from the carrier tape 15. After peeling off the carrier tape 15, the components are taken out by the mounting head 35.

The used carrier tape from which the parts have been removed is sent to the cutting section 55. The cutting unit 55 cuts the used carrier tape into small pieces of waste tape 57 by driving a tape cutter by a cylinder 67 . This waste tape 57 is collected into a collection section 61 provided at the bottom of the cart 27 via a chute section 59 connected to the lower part of the cutting section 55.

In the component mounting device 11 , the chute section 59 is fixed to the housing section 63 of the cutting section 55 using a fixing screw 71 . The chute section 59 is arranged between the cutting section 55 and the truck 27, and covers the maintenance area 111 (see FIG. 3). When the chute section 59 is removed, the component mounting device 11 can access the maintenance area 111 located on the back side of the chute section 59. In other words, it is necessary to remove the chute portion 59 during maintenance. The maintenance area 111 is provided with a control unit 45, a motor driver, a vacuum pump, and the like.

In the component mounting device 11, when maintenance work in the maintenance area 111 becomes necessary, the chute section 59 is removed by the operator after the cart 27 is removed.

In the component mounting device 11, when the chute portion 59 is removed, the cutoff portion 73 cuts off the supply of power to the cylinder 67. When the supply of power to the cylinder 67 is cut off, the movable blade 69 exposed at the lower part of the cutting section 55 becomes inoperable and stops.

The component mounting device 11 according to the first embodiment takes out a component from a tape member containing a plurality of components and mounts the component onto a board 13. The component mounting device 11 includes a cutting section 55 that cuts the tape member after the component has been taken out, a cylinder 67 that drives the cutting section 55, and a cutoff section 73 that cuts off the supply of power to the cylinder 67. and a chute portion 59 through which the tape member passed. When the chute section 59 is removed, the supply of power is cut off by the cutoff section 73.

According to the component mounting device 11, when the cover portion covering the fixed blade 65 and the movable blade 69 (that is, the chute portion 59) is removed, the cutoff portion 73 that cuts off the drive source (main air) to the cutting portion 55 is activated. By providing this, it is possible to ensure that the exposed movable blade 69 cannot be operated. According to the component mounting device 11, the power supply to the cylinder 67 is mechanically cut off, so compared to a structure in which electric safety measures are taken using a conventional safety switch, there is a possibility that the failure of control equipment or manual It is possible to reliably eliminate cutter malfunctions due to operation. Therefore, in a component mounting device with a built-in tape cutter, the safety of workers can be ensured by accurately shutting off the drive source of the exposed cutter blade during maintenance.

Further, the blocking section 73 is provided on the side surface of the chute section 59.

Further, in this component mounting apparatus 11, a maintenance area 111 inside the apparatus is covered by a chute section 59. A cart 27 is further arranged on the opposite side of the maintenance area 111 with the chute section 59 in between. Therefore, first, after the truck 27 is removed, the chute portion 59 is removed in the same direction (-Y direction) to open the maintenance area 111. In the component mounting device 11, the blocking section 73 is provided on the side surface of the chute section 59, so that the blocking section 73 does not get in the way when the chute section 59 is removed. Moreover, the disconnection or connection work of the blocking part 73, which is performed with the trolley 27 removed, can be easily performed on the side of the chute part 59 within the reach of the operator.

Further, in the component mounting device 11, the drive section is a cylinder 67 driven by fluid, the cutoff section 73 is a connector for piping to which fluid is supplied, and the connectors include the first connector and the first connector. It has a second connecting part connected to the first connecting part, and when the chute part 59 is removed, the first connecting part comes off from the second connecting part and the supply of fluid is cut off.

In this component mounting device 11, the driving section is a cylinder 67 driven by fluid (air). The cylinder 67 drives the movable blade 69 of the cutting section 55. The cutoff section 73 is a connection tool for piping that supplies air to the cylinder 67, and includes a first connection section and a second connection section. In the first embodiment, the first connecting portion is the male side (nipple 77) of the one-touch coupler 75. The second connecting portion becomes the female side (socket 79) of the one-touch coupler 75.

The one-touch coupler 75 allows piping to be connected or removed by attaching and detaching the nipple 77 and the socket 79. The connected state of the one-touch coupler 75 is maintained by a slidable sleeve 81 provided in the socket 79. At the time of removal, the sleeve 81 can be removed from the nipple 77 with one touch by sliding against the biasing force of the sleeve spring.

In the socket 79 from which the nipple 77 has been removed, the end of the conduit is automatically closed by the built-in valve. At the time of connection, the connected state can be maintained with one touch simply by fitting the nipple 77 and the socket 79. When the one-touch coupler 75 is in the connected state, the valve of the socket 79 is opened and the piping is connected.

Therefore, when the chute section 59 is removed, the nipple 77 comes off from the socket 79, and the supply of air to the cutting section 55 is always cut off.

Further, in the component mounting device 11 according to the first embodiment, when the chute portion 59 is removed, the first connecting portion is separated from the second connecting portion as one with the chute portion 59.

In the component mounting device 11 according to the first embodiment, the nipple 77, which is the first connecting portion, is integrally fixed to the chute portion 59. The socket 79, which is the second connecting portion, is fixed to the pedestal 19, for example. A piston 87 is built into the cylinder 67 . The cylinder 67 drives a piston rod 93 (that is, the movable blade 69) connected to the piston 87 forward and backward by alternately supplying air to two chambers sandwiching the piston 87. Two pneumatic circuits are connected to the cylinder 67 from a pneumatic source such as a compressor. These two systems of pneumatic circuits bypass the chute section 59 from the mount 19 and then return to the mount 19 again. Therefore, four one-touch couplers 75 are arranged between the pedestal 19 and the chute section 59. Of these, the chute portion 59 is integrally provided with four nipples 77, which are first connecting portions. The pedestal 19 is provided with four sockets 79 corresponding to the respective nipples 77.

According to the component mounting device 11, when the chute portion 59 is removed, the four nipples 77 are separated from the socket 79 together with the chute portion 59, and the air supply to the cylinder 67 is simultaneously and reliably cut off.

In addition, in the component mounting apparatus 11 according to the first embodiment, by using the one-touch coupler 75 in the cutoff part 73, it is possible to facilitate the work of attaching and removing the chute part 59.

In addition, the nipples 77 of the one-touch couplers 75 are of a sliding type, and each one-touch coupler 75 can be connected and disconnected independently, so that it is possible to easily remove a plurality of one-touch couplers 75.

Further, since the socket 79 in the one-touch coupler 75 is fixed in a floating manner, when the chute part 59 is attached, the plurality of one-touch couplers 75 can be aligned (aligned) at the same time, and the blocking part 73 equipped with the plurality of one-touch couplers 75 can be connected at once.

[Embodiment 2]
Next, an example of the component mounting device 113 according to the second embodiment will be described.

FIG. 12 is a pneumatic control circuit diagram during operation of the component mounting device 113 according to the second embodiment. In the second embodiment, the same members and parts as those described in the first embodiment are given the same reference numerals and redundant explanations will be omitted. Furthermore, in each of the pneumatic circuit diagrams below, in order to simplify the explanation, the ports of the pneumatic control elements are mainly designated by symbols, and the explanation of the piping is omitted.

In the component mounting device 113 according to the second embodiment, the blocking section 73 is a valve that controls the flow of fluid. The component mounting device 113 shuts off the supply of fluid to the cylinder 67 using this valve.

In the component mounting device 113, this valve is a mechanical valve 115. The mechanical valve 115 cuts off the supply of fluid to the cylinder 67 in conjunction with the removal of the chute portion 59. Mechanical valve 115 is provided between the pneumatic source and cylinder 67.

A cutter operation control valve 117 is interposed between the mechanical valve 115 and the cylinder 67. Cutter operation control valve 117 is a 5-port, 2-position directional control valve. The cutter operation control valve 117 is switched between two positions by electromagnetic operation by a solenoid 119. Solenoid 119 is controlled by control section 45 . The control unit 45 controls the cutter operation control valve 117 based on the truck detection signal input from the truck presence/absence detection switch 51 .

A mechanical valve 115 is interposed between a pneumatic source and this cutter operation control valve 117. That is, the mechanical valve 115 is disposed closer to the air pressure source than the cutter operation control valve 117 on the upstream side in the air supply direction. Therefore, in the cutting section 55, if the air from the pneumatic source is cut off by the operation of the mechanical valve 115, the cylinder 67 will stop regardless of the operating state of the cutter operation control valve 117. This is because air from the pneumatic source is cut off on the upstream side of the cutter operation control valve 117.

Mechanical valve 115 is a 2-port, 2-position directional control valve. The mechanical valve 115 can be switched between two positions by pushing the pusher 121 . When the chute portion 59 is attached to the mechanical valve 115, the pusher 121 is pushed in, and air from the pneumatic source is sent to the cutter operation control valve 117 (during operation in FIG. 12). On the other hand, when the chute portion 59 of the mechanical valve 115 is removed, the return spring 122 switches the ports, cuts off the air supply to the cutter operation control valve 117, and at the same time the presser 121 becomes in the protruding state (see FIG. 13). situation).

When the component mounting device 113 operates as shown in FIG. 12, when air from the pneumatic source is supplied to the mechanical valve 115, the mechanical valve 115 supplies air from the first port 123 to the cutter operation control valve 117. . The cutter operation control valve 117 to which air is supplied supplies air from the first supply port 125 to the advance port 127 of the cylinder 67 when the truck presence/absence detection switch 51 is ON, the solenoid 119 is turned ON. In the cylinder 67 to which air is supplied to the advancing port 127, the piston 87 moves in the direction of advancing the piston rod 93. At this time, air from the retreat port 129 of the cylinder 67 is exhausted to the first exhaust port 131 of the cutter operation control valve 117. This exhaust gas is exhausted to the atmosphere via a silencer 133 connected to the cutter operation control valve 117. Thereby, the cutting section 55 drives the movable blade 69 to advance.

FIG. 13 is a pneumatic control circuit diagram when the component mounting apparatus 113 according to the second embodiment is stopped. On the other hand, when the component mounting device 113 is stopped as shown in FIG. 13, when the chute portion 59 is removed, the presser 121 protrudes and air from the pneumatic source is shut off by the mechanical valve 115. As a result, air is no longer supplied from the mechanical valve 115 to the cutter operation control valve 117. In this state, the second port 135 of the mechanical valve 115, which is open to the atmosphere, is connected to the cutter operation control valve 117. In the cutter operation control valve 117 connected to the second port 135, when the truck presence/absence detection switch 51 is OFF, the solenoid 119 is OFF, and the second supply port 137 is connected to the retreat port 129 of the cylinder 67. In the cylinder 67 connected to the retraction port 129, the piston 87 moves in the direction of retracting the piston rod 93 by a release spring or the like (not shown). At this time, in the cylinder 67, air from the second supply port 137 flows into the retreat port 129, and air from the advance port 127 is exhausted to the second exhaust port 139 of the cutter operation control valve 117. This exhaust gas is exhausted to the atmosphere via a silencer 133 connected to the cutter operation control valve 117. As a result, the cutting section 55 drives the movable blade 69 backward and stops.

Next, the operation of the component mounting device 11 according to the second embodiment will be explained.

In the component mounting device 113 according to the second embodiment, the driving section is a cylinder 67 driven by fluid, the blocking section 73 is a valve that controls the flow of fluid, and when the chute section 59 is removed, The valve shuts off the fluid supply to the cylinder 67.

In the component mounting device 113 according to the second embodiment, the supply of air to the cylinder 67 is cut off by a valve instead of the one-touch coupler 75 used in the component mounting device 11 according to the first embodiment. According to this component mounting device 113, in the pneumatic circuit connected to the pneumatic pressure source, a valve is provided on the most upstream side closest to the pneumatic pressure source, so that the supply of air to the cylinder 67 is cut off by one valve. It becomes possible to do so. As a result, the pneumatic circuit can be constructed simply and the cost of parts can be reduced.

Further, in the component mounting device 113, the valve is a mechanical valve 115, and in conjunction with the removal of the chute portion 59, the mechanical valve 115 shuts off the supply of fluid to the cylinder 67.

In this component mounting device 113, since the valve is a mechanical valve 115, the presence or absence of the chute portion 59 can be detected by the presser 121, and the pneumatic circuit to the cylinder 67 can be mechanically interrupted. As a result, compared to a configuration in which the cutter operation control valve 117 is controlled only by the trolley presence/absence detection switch 51, malfunctions of the cutter due to malfunctions of control equipment or manual operations can be reliably eliminated.

[Details leading to Embodiment 3 or 4]
In the configuration of Patent Document 1, a safety measure is taken in which the cutter section is not operated by detecting the presence or absence of a cart using a cart presence/absence detection sensor. However, the cutter operates even if the cover covering the cutter blade is not attached. In other words, the cutter will operate even if the tape chute is removed if the trolley presence detection sensor responds, so it is necessary to ensure safety by preventing the cutter from operating when the tape chute is not attached. .

Therefore, in Embodiment 3 or 4 below, even in a configuration with a built-in tape cutter, parts are installed to ensure worker safety by accurately shutting off the drive source of the exposed cutter blade during maintenance. An example of the device will be explained.

[Embodiment 3]
Next, an example of a component mounting apparatus according to Embodiment 3 will be described.

FIG. 14 is a side view of the component mounting device 141 according to the third embodiment. In Embodiment 3, the same members and parts as those described in Embodiment 1 and Embodiment 2 are given the same reference numerals and redundant explanations will be omitted.

The component mounting device 141 according to the third embodiment includes a cutting section 55, a control section 45, a chute section 59, a truck presence/absence detection switch 51, and a first detection section. The first detection section is a chute section detection sensor 143.

The chute portion detection sensor 143 detects the presence or absence of the chute portion 59. The chute portion detection sensor 143 is fixed to the pedestal 19 at a position facing, for example, a side surface of the chute portion 59 . As the chute portion detection sensor 143, a photoelectric sensor or the like is used, for example. In addition, any sensor such as a pressure-sensitive sensor can be used as the first detection section as long as it can detect the presence or absence of the chute section 59.

FIG. 15 is a pneumatic control circuit diagram during operation of the component mounting device 141 shown in FIG. 14. In the component mounting device 141, the control section 45 controls the cylinder 67 so that the cutting section 55 is driven while the chute section detection sensor 143 is detecting the chute section 59.

When the component mounting device 141 operates as shown in FIG. 15, air is supplied from a pneumatic source to the cutter operation control valve 117. The cutter operation control valve 117 supplied with air supplies air from the first supply port 125 to the advance port 127 of the cylinder 67 when the solenoid 119 is turned on. In the cylinder 67 to which air is supplied to the advancing port 127, the piston 87 moves in the direction of advancing the piston rod 93. At this time, air from the retreat port 129 of the cylinder 67 is exhausted to the first exhaust port 131 of the cutter operation control valve 117. This exhaust gas is exhausted to the atmosphere via a silencer 133 connected to the cutter operation control valve 117. Thereby, the cutting section 55 drives the movable blade 69 to advance.

FIG. 16 is a pneumatic control circuit diagram when the component mounting device 141 shown in FIG. 14 is stopped. In the component mounting device 141, the control section 45 controls the cylinder 67 so that the cutting section 55 is not driven when the chute section detection sensor 143 is not detecting the chute section 59.

When the component mounting device 141 is stopped as shown in FIG. 16 and the chute portion 59 is removed, the chute portion detection sensor 143 detects that the chute portion 59 is absent. When the control section 45 receives the no chute section signal from the chute section detection sensor 143, it controls the solenoid 119 to stop the cutter operation control valve 117. The cutter operation control valve 117 in the stopped state supplies air from the pneumatic source to the retreat port 129 of the cylinder 67 from the second supply port 137. In the cylinder 67 to which air is supplied to the retraction port 129, the piston 87 moves in the direction of retracting the piston rod 93. At this time, the cylinder 67 exhausts the air in the advance port 127 to the second exhaust port 139 of the cutter operation control valve 117. This exhaust gas is exhausted to the atmosphere via a silencer 133 connected to the cutter operation control valve 117. As a result, the cutting section 55 drives the movable blade 69 backward and stops.

The component mounting device 141 further includes a truck presence/absence detection switch 51 that is a second detection section that detects the truck 27. Therefore, the component mounting device 141 allows the control section 45 to drive the cutting section 55 only when the chute section 59 is detected by the chute section detection sensor 143 and the trolley 27 is detected by the trolley presence detection switch 51. Then, the cylinder 67 is controlled.

Next, the operation of the component mounting device 141 according to the third embodiment will be explained.

(chute part detection sensor 143), and in a state where the chute part 59 is not detected by the chute part detection sensor 143, the control part 45 controls the cylinder 67 so that the cutting part 55 is not driven.

In the component mounting device 141 according to the third embodiment, the chute portion detection sensor 143 is connected to the control portion 45 . When the control section 45 receives the chute section absence signal from the chute section detection sensor 143, it drives the cylinder 67 in a direction in which the movable blade 69 retreats, and stops the cylinder 67. Thereby, in the component mounting device 11 in which the cutting section 55 is built-in, safety can be ensured by controlling the drive of the cutter blade that is exposed during maintenance.

Further, according to the component mounting device 141, by attaching the chute detection sensor 143, which is a small electronic component, to the mount 19 near the chute and connecting the wiring to the control unit 45, the cylinder 67, which is the drive unit, can be controlled. can. As a result, the pneumatic circuit can be configured without changing, and the cost of parts can be reduced. Furthermore, since there is no need to provide a detour in the pneumatic circuit, this is advantageous in terms of downsizing the device.

As a result, according to the component mounting device 141, malfunction of the cylinder 67 due to erroneous detection by the chute portion detection sensor 143 can be suppressed, and safety during maintenance can be more reliably ensured.

[Embodiment 4]
Next, an example of a component mounting apparatus according to Embodiment 4 will be described.

FIG. 17 is a pneumatic control circuit diagram during operation of the component mounting device 145 according to the fourth embodiment.
