[0028] Figure 1 A substrate working system 10 is shown. Figure 1 The system 10 shown is a system for mounting electronic components on a circuit board. The substrate operation system 10 is composed of a feeder storage warehouse 20, five mounting devices 22, and a feeder replacement device 26. Moreover, the feeder storage warehouse 20 and the five mounting devices 22 are arranged in a row in a state of being adjacent to each other in the order of one feeder storage warehouse 20 and five mounting devices 22. In addition, the feeder replacement device 26 is arranged on the front side of the feeder storage warehouse 20 and the mounting device 22 ( Figure 1In the following description, the arrangement direction of the feeder storage 20 and the mounting device 22 is referred to as the X direction, the horizontal direction at right angles to the X direction is referred to as the Y direction, and the direction orthogonal to the X direction and the Y direction is referred to as the Z direction. In addition, in the X direction, the side where the feeder storage 20 is arranged is referred to as the upstream side, and the side where the mounting device 22 is arranged is referred to as the downstream side.

[0029] The five mounting devices 22 are substantially the same structure as each other. Figure 2 As shown, the five mounting devices 22 are respectively provided with a transport device 30 , a mounting head 32 , a mounting head moving device (hereinafter, sometimes simply referred to as a “moving device”) 34 , and a supply device 36 .

[0030] The transport device 30 includes two conveyor devices 50. The two conveyor devices 50 are arranged on a base 52 in parallel with each other and extend in the X direction. The two conveyor devices 50 convey the circuit substrate 57 supported by each conveyor device 50 in the X direction by means of an electromagnetic motor (not shown). In addition, each conveyor device 50 has a substrate holding device (not shown) to fixedly hold the circuit substrate 57 at a predetermined position.

[0031] The mounting head 32 mounts electronic components on the circuit substrate 57. In detail, the mounting head 32 has a suction nozzle 60 disposed on the lower end surface. The suction nozzle 60 is connected to a positive and negative pressure supply device (not shown) via negative pressure air and positive pressure air passages. The suction nozzle 60 uses negative pressure to suck and hold the electronic components, and uses positive pressure to detach the held electronic components. In addition, the mounting head 32 has a suction nozzle lifting device (not shown) for raising and lowering the suction nozzle 60. Through the suction nozzle lifting device, the mounting head 32 changes the position of the held electronic component in the up and down direction.

[0032] The moving device 34 is a device for moving the mounting head 32 to any position on the base 52. In detail, the moving device 34 is composed of an X-direction sliding mechanism 70 and a Y-direction sliding mechanism 72. The Y-direction sliding mechanism 72 is arranged on a beam 73 mounted on the base 52, and has a pair of Y-direction guide rails 74. And, the pair of Y-direction guide rails 74 are arranged in a manner extending in the Y direction. On the other hand, the X-direction sliding mechanism 70 has an X-direction guide rail 76, and the X-direction guide rail 76 is held on the pair of Y-direction guide rails 74 in a manner extending in the X direction. The Y-direction sliding mechanism 72 has an electromagnetic motor (not shown in the figure), and the X-direction guide rail 76 is moved to any position in the Y direction by the drive of the electromagnetic motor. The X-direction guide rail 76 holds the slide 80 in a manner that can move along its own axis. The X-direction sliding mechanism 70 has an electromagnetic motor (not shown in the figure), and the slide 80 is moved to any position in the X direction by the drive of the electromagnetic motor. The mounting head 32 is mounted on the slide 80. With such a structure, the mounting head 32 is moved to any position on the base 52 by the moving device 34 .

[0033] The supply device 36 is disposed at the front end of the base 52 and has a plurality of tape feeders 90. Figure 3 As shown, each tape feeder 90 has a tape reel 92, a delivery device 94 and a stripping device 96, and supplies electronic components at the end of the upper surface. In detail, a tape component 98 is wound on the tape reel 92, and the tape component 98 is pulled out from the tape reel 92 to the tape guide 100. The tape component 98 is obtained by taping the electronic components, and feed holes (not shown) are formed at a predetermined pitch. The feed holes mesh with the tape guide gear 102 of the delivery device 94. And, the tape guide gear 102 is rotated by the electromagnetic motor 104. With such a structure, the tape component 98 is delivered to the supply position.

[0034] In addition, the stripping device 96 has a film stripping mechanism 106 and a gear mechanism 108. The film stripping mechanism 106 is a mechanism for stripping the top film 110 from the tape component 98, and is arranged in front of the opening 112 formed at the upper surface end of the tape feeder 90. The gear mechanism 108 is a mechanism for pulling the top film 110 stripped from the tape component 98 into the film recovery unit 114. With such a structure, the top film 110 is stripped from the tape component 98, and the electronic components contained in the tape component 98 are exposed at the opening 112, and the exposed electronic components are held by the suction nozzle 60 of the mounting head 32. That is, the opening 112 becomes the electronic component supply position of the tape feeder 90. In addition, a tape guide path 116 is formed on the side of the opening 112 in the feeding direction of the tape component 98 in a downward manner. Through the tape guide path 116, the waste tape 118 from which the electronic components are taken out of the tape component 98 is discharged.

[0035] In addition, if Figure 2 As shown, the tape feeder 90 can be detachably mounted on the tape feeder holding platform 120 fixedly provided at the end portion of the front side of the base 52. A plurality of rails (not shown) extending in the Y direction are arranged in the X direction on the tape feeder holding platform 120, and the tape feeder 90 can be detachably mounted on each rail.

[0036] In addition, a storage case 140 is provided below the tape feeder holding platform 120. In the storage case 140, as in the tape feeder holding platform 120, a plurality of rails (not shown) extending in the Y direction are arranged in the X direction, and the tape feeder 90 is detachably mounted on each rail.

[0037] In addition, if Figure 1 As shown, in the feeder storage 20, a storage space 150 is formed at the same height as the tape feeder holding table 120 of the mounting device 22. The storage space 150 is a space for storing the storage rack 160. Figure 4 As shown, the storage rack 160 is a box-shaped storage rack 160 with an open front surface. The height dimension of the interior of the box-shaped storage rack 160 is slightly larger than the height dimension of the tape feeder 90, and the depth dimension of the interior of the storage rack 160 is slightly larger than the depth dimension of the tape feeder 90. Moreover, the width dimension of the interior of the storage rack 160 is greater than N times (for example, 30 times) the width dimension of the tape feeder 90. In the interior of the storage rack 160 of this shape, N tape feeders 90 can be arranged and stored. In addition, N rails 164 are formed on the lower surface of the top plate 162 of the storage rack 160 in a manner extending in the front-to-back direction. Therefore, by embedding the upper end of the tape feeder 90 into the rail 164, the tape feeder 90 is pressed into the interior of the storage rack 160, so that the tape feeder 90 is stored in a positioned state in the interior of the storage rack 160.

[0038] In addition, the inner dimension of the storage space 150 in the depth direction is slightly larger than the outer dimension of the storage rack 160 in the depth direction, and the inner dimension of the storage space 150 in the width direction, i.e., the X direction, is slightly larger than twice the outer dimension of the storage rack 160 in the width direction. In addition, the storage space 150 is open at the top. Figure 1 As shown, two storage racks 160 can be arranged and stored in the storage space 150 along the X direction.

[0039] In addition, the feeder replacement device 26 performs the replacement operation of the tape feeder 90 on the feeder storage 20 and the five installation devices 22. Specifically, an upper guide rail 170 and a lower guide rail 172 are arranged on the front surface of the feeder storage 20 and the five installation devices 22 so as to extend in the X direction. And the feeder replacement device 26 is held by the upper guide rail 170 and the lower guide rail 172 so as to be slidable in the X direction, and is moved to an arbitrary position in the X direction by the drive of an electromagnetic motor (not shown).

[0040] In addition, if Figure 2 As shown, the feeder replacement device 26 has a lifting device 180, a horizontal moving device 182 and a clamping mechanism 184. The lifting device 180 has a pair of Z-direction guide rails 186, which are arranged on the front side of the tape feeder holding table 120 and the storage housing 140 of the mounting device 22 in a manner extending in the Z direction. In addition, the horizontal moving device 182 has an X-direction guide rail 188, which is held on the pair of Z-direction guide rails 186 in a manner extending in the X direction. In addition, the X-direction guide rail 188 is moved to an arbitrary position in the Z direction by the drive of a Z-direction motor (omitted from the figure). In addition, the X-direction guide rail 188 holds the clamping mechanism 184 in a manner that can move along its own axis. The clamping mechanism 184 is moved to an arbitrary position in the X direction by the drive of an X-direction motor (omitted from the figure). In addition, the clamping mechanism 184 can be extended and retracted in the Y direction, and is extended and retracted in the Y direction by the drive of a telescopic motor (omitted from the figure). In addition, a clamp 190 for clamping the tape feeder 90 is provided at the front end of the clamp mechanism 184. With such a structure, the feeder replacement device 26 automatically replaces the tape feeder 90 between the tape feeder holding table 120, the storage case 140, and the storage rack 160.

[0041] According to the above structure, in the substrate operation system 10, the circuit substrate 57 is transported by the transport device 30 inside the five mounting devices 22, and the electronic components are mounted on the circuit substrate 57 by the mounting device 22. Specifically, first, the circuit substrate 57 is carried into the mounting device arranged at the most upstream among the five mounting devices 22. Moreover, in the mounting device, the circuit substrate 57 is transported to the operation position and fixedly held at the position. In addition, the tape feeder 90 mounted on the tape feeder holding table 120 delivers the tape component 98 and supplies the electronic component at the supply position. And, the mounting head 32 moves above the supply position of the electronic component and holds the electronic component by suction through the suction nozzle 60. Then, the mounting head 32 moves above the circuit substrate 57 and mounts the held electronic component on the circuit substrate. When the mounting operation of the electronic component on the circuit substrate is completed, the circuit substrate is transported toward the downstream and is carried into the mounting device arranged on the downstream side. And, the above-mentioned mounting operation is performed sequentially by each mounting device, thereby producing a circuit substrate with electronic components mounted thereon.

[0042] In this way, the mounting device 22 is configured to hold the electronic components supplied by the tape feeder 90 by suction by the suction nozzle 60 of the mounting head 32, and to mount the held electronic components on the circuit board. In the mounting device 22 configured in this way, in order to cope with the replenishment of electronic components, production change adjustment, etc., for example, the tape feeder 90 mounted on the tape feeder holding table 120 is replaced by the feeder replacement device 26. That is, the tape feeder 90 to be replaced is removed from the tape feeder holding table 120 by the clamping mechanism 184 of the feeder replacement device 26. Then, the removed tape feeder 90 is stored in an empty slot of the storage case 140 or the storage rack 160. Next, the tape feeder to be mounted from the storage case 140 or the storage rack 160 to the tape feeder holding table 120 is clamped by the clamping mechanism 184 of the feeder replacement device 26. Then, the tape feeder 90 clamped by the clamping mechanism 184 is mounted on the tape feeder holding table 120 .

[0043] Therefore, the storage rack 160 stores the tape feeder 90 for supplying electronic components required for replenishment, production changeover, etc., in the substrate operation system 10. Figure 5 The automatic transport device 200 and the transport trolley 202 shown in the figure automatically replace the storage rack 160. Figure 6 As shown in the figure, the automatic transport device 200 includes a pair of driving wheels (only one side of the pair of driving wheels is shown in the figure) 212 and a pair of steering wheels (only one side of the pair of steering wheels is shown in the figure) 214 arranged inside the housing 210. Thus, the automatic transport device 200 can automatically move along an arbitrary path. In addition, the side where the pair of steering wheels 214 are arranged is recorded as the front side, and the side where the pair of driving wheels 212 are arranged is recorded as the rear side.

[0044] In addition, a display monitor 218 is provided at the center of the front side of the top plate 216 of the housing 210, and the operating state of the automatic transport device 200 is displayed on the display monitor 218. A plurality of operation switches 220 are provided on the left and right of the display monitor 218. One of the plurality of operation switches 220 is an emergency stop switch 220a for emergency stopping the operation of the automatic transport device 200. By operating the emergency stop switch 220a, the operation of the driving wheel 212 and the steering wheel 214 is emergency stopped. In addition, a pair of front side pins 222 are provided vertically on the front side of the top plate 216 of the housing 210 so as to sandwich the display monitor 218 and the plurality of operation switches 220. On the other hand, a rear side pin 224 is provided vertically at the center of the rear side of the top plate 216 of the housing 210.

[0045] In addition, if Figure 7 as well as Figure 8 As shown, the transport cart 202 has a door-shaped base 230, a plurality of transport rollers 232, a plurality of operating switches 234, and a pair of covers 236. Figure 8 It is a perspective view of the transport cart 202 in which the plurality of transport rollers 232, the plurality of operation switches 234, and the cover 236 are omitted.

[0046] The base 230 is composed of a top plate 240 of a substantially square shape and a pair of supporting walls 242 supporting the top plate 240. A cutout 244 having a substantially rectangular cutout is formed on one side edge of the top plate 240. In addition, the side edge of the top plate 240 on which the cutout 244 is formed is recorded as the front side, and the side edge of the top plate 240 opposite to the side edge on which the cutout 244 is formed is recorded as the rear side. In addition, a pair of supporting walls 242 are provided in a manner extending downward from a pair of side edges other than the side edge on the front side and the side edge on the rear side of the top plate 240, i.e., a pair of side edges on the left and right sides of the top plate 240. Thus, the base 230 is formed in a door shape opening to the front side and the rear side. In addition, a pair of casters 248 are provided at the lower end of the supporting wall 242 on the front side and the rear side. Thus, the base 230 can be moved to any position. In addition, the inner dimension between the pair of support walls 242 of the base 230 is slightly larger than the length dimension in the left-right direction of the automatic transport device 200. In addition, the length dimension in the front-back direction of the base 230 is slightly larger than the length dimension in the front-back direction of the automatic transport device 200. In addition, the height dimension of the lower surface of the top plate 240 of the base 230 is slightly larger than the height dimension of the automatic transport device 200.

[0047] In addition, if Figure 7As shown, a plurality of conveying rollers 232 are arranged in a front-to-rear direction in a posture extending in the left-right direction above the top plate 240 of the base 230. In addition, the plurality of conveying rollers 232 can rotate around the axis extending in the left-right direction. In addition, the plurality of conveying rollers 232 can rotate in any direction by being driven by an electromagnetic motor (not shown).

[0048] In addition, a plurality of operating switches 234 are arranged on the front side of the plurality of conveying rollers 232 above the top plate 240 of the base 230. One of the plurality of operating switches 234 is an emergency stop switch 234a for emergency stopping the operation of the conveying trolley 202, and by operating the emergency stop switch 234a, the operation of the conveying rollers 232 is emergency stopped. In addition, a pair of covers 236 are arranged in a manner covering a pair of side edges on the left and right sides of the top plate 240 of the base 230, and the plurality of conveying rollers 232 and the plurality of operating switches 234 are exposed between the pair of covers 236.

[0049] In addition, if Figure 8 As shown, a substantially U-shaped pin receiving member 250 is fixed to the lower surface of the top plate 240 of the base 230 at the center of the end portion on the rear side of the top plate 240. The substantially U-shaped pin receiving member 250 is open to the front side, and a recess 252 is formed from the opening toward the inside of the pin receiving member 250. In addition, the inner dimension of the recess 252 is slightly larger than the outer diameter of the rear side pin 224 of the automatic handling device 200. In addition, a pair of guide members 256 are fixed to the lower surface of the top plate 240 in a manner extending substantially in a V-shape from the left and right sides of the opening of the recess 252 of the pin receiving member 250 to the oblique front side of the top plate 240. In addition, the cutout portion 244 cut into a substantially rectangular shape of the top plate 240 is formed so that the length direction extends along the left and right directions of the top plate 240, and the inner dimension of the left and right directions of the cutout portion 244 is slightly larger than the maximum separation distance of the pair of front side pins 222 of the automatic handling device 200. The maximum separation distance between the pair of front pins 222 is a distance obtained by adding twice the radius of the front pin 222 to the distance between the axis center of one of the pair of front pins 222 and the axis center of the other.

[0050] With such a structure, the transport trolley 202 is installed in the automatic transport device 200 in a positioned state. Specifically, for example, the operator allows the rear of the automatic transport device 200 to enter from the opening in front of the transport trolley 202. Then, the automatic transport device 200 is allowed to enter the interior of the transport trolley 202 until the entire automatic transport device 200 is located below the transport trolley 202. At this time, Fig. 9As shown, the rear side pins 224 of the automatic transport device 200 are guided by a pair of guides 256 of the transport trolley 202 and accommodated in the pin accommodation member 250. In addition, the pair of front side pins 222 of the automatic transport device 200 are positioned at the corners of the cutout portion 244 of the transport trolley 202. Thus, the transport trolley 202 is mounted on the automatic transport device 200 in a positioned state.

[0051] In addition, a pair of locking mechanisms 260 are provided at the side edge of the front side of the top plate 240 of the transport trolley 202, and when the transport trolley 202 is installed on the automatic transport device 200, the pair of front side pins 222 of the automatic transport device 200 are locked by the pair of locking mechanisms 260. That is, the transport trolley 202 is locked to the automatic transport device 200 by the pair of locking mechanisms 260. The locking mechanisms 260 will be described in detail later. In addition, when the transport trolley 202 is installed on the automatic transport device 200, the transport trolley 202 is electrically connected to the automatic transport device 200, which will be described in detail later.

[0052] In this way, if the transport trolley 202 is installed in the automatic transport device 200 in a locked state and the transport trolley 202 is electrically connected to the automatic transport device 200, the storage rack 160 stored in the feeder storage 20 is automatically replaced by the automatic transport device 200 and the transport trolley 202. Fig.10 As shown, the height of the lower surface of the storage space 150 of the storage storage rack 160 of the feeder storage warehouse 20 is substantially the same as the height of the upper surface of the transport trolley 202 in the state of being installed in the automatic transport device 200. In addition, on the lower surface of the storage space 150, a plurality of transport rollers 266 are arranged in a Y direction in a posture extending in the X direction. And, each of these plurality of transport rollers 266 can rotate around the axis extending in the X direction. In addition, the plurality of transport rollers 266 are driven by an electromagnetic motor (not shown) to rotate in an arbitrary direction.

[0053] With such a structure, in the feeder storage warehouse 20, for example, the storage rack 160 stored in the storage space 150 is automatically transferred to the transport trolley 202 installed on the automatic transport device 200. In detail, the transport trolley 202 installed on the automatic transport device 200 moves to a position opposite to the storage space 150 containing the storage rack (hereinafter referred to as "unnecessary rack 160a") through the operation of the automatic transport device 200. At this time, the transport trolley 202 moves in a manner in which the rear side of the transport trolley 202 is opposite to the storage space 150. Then, the multiple transport rollers 266 of the feeder storage warehouse 20 rotate in the direction of carrying out the unnecessary rack 160a, and the multiple transport rollers 232 of the transport trolley 202 rotate in the direction of carrying in the unnecessary rack 160a. As a result, the unnecessary rack 160a stored in the storage space 150 is automatically transferred to the transport trolley 202 installed on the automatic transport device 200.

[0054] In addition, if Fig.11 As shown, a rack management device 280 is also provided on the layer 270 where the substrate operation system 10 is provided. The rack management device 280 is a device for managing the storage racks 160. Like the feeder storage warehouse 20, the rack management device 280 has a storage space 282, and can store two storage racks 160 in a horizontal arrangement in the storage space 282. Fig.11 In the rack management device 280 shown, there is a storage rack (hereinafter referred to as "necessary rack 160b"), and the necessary rack 160b stores the tape feeder 90 for supplying electronic components to be installed in the installation device 22. In addition, an empty space is provided next to the necessary rack 160b. In addition, a plurality of conveying rollers 284 are provided on the lower surface of the storage space 282 of the rack management device 280, similarly to the storage space 150 of the feeder storage warehouse 20, and these plurality of conveying rollers 284 are also driven by an electromagnetic motor (omitted in the figure) to rotate in any direction.

[0055] In addition, if the unnecessary rack 160a is transferred from the feeder storage 20 to the transport cart 202, the transport cart 202 is moved to a position opposite to the empty space of the rack management device 280 by the operation of the automatic transport device 200. Then, the multiple transport rollers 232 of the transport cart 202 rotate in the direction of carrying out the unnecessary rack 160a, and the multiple transport rollers 284 of the rack management device 280 rotate in the direction of carrying in the unnecessary rack 160a. As a result, the unnecessary rack 160a placed on the transport cart 202 is automatically transferred to the storage space 282 of the rack management device 280. Next, the transport cart 202 is moved to a position opposite to the necessary rack 160b stored in the storage space 282 of the rack management device 280 by the operation of the automatic transport device 200. Then, the plurality of conveying rollers 284 of the rack management device 280 rotates in the direction of carrying out the necessary rack 160b, and the plurality of conveying rollers 232 of the conveying cart 202 rotates in the direction of carrying in the necessary rack 160b. Thus, the necessary rack 160b stored in the rack management device 280 is automatically transferred to the conveying cart 202.

[0056] Next, the transport trolley 202 carrying the necessary rack 160b is moved to an empty space of the feeder storage 20, that is, a position opposite to the space where the unnecessary rack 160a is placed, by the operation of the automatic transport device 200. Then, the plurality of transport rollers 232 of the transport trolley 202 rotate in the direction of carrying out the necessary rack 160b, and the plurality of transport rollers 266 of the feeder storage 20 rotate in the direction of carrying in the necessary rack 160b. Thus, the necessary rack 160b placed on the transport trolley 202 is automatically transferred to the storage space 150 of the feeder storage 20.

[0057] In this way, the unnecessary rack 160a stored in the feeder storage 20 is automatically replaced with the necessary rack 160b by the automatic transport device 200 and the transport trolley 202. In addition, for example, when the transport trolley 202 moves between the feeder storage 20 and the rack management device 280 by the operation of the automatic transport device 200, in the event of a malfunction, the operator operates the emergency stop switch 220a of the automatic transport device 200. As a result, the operation of the automatic transport device 200 is urgently stopped, and the movement of the transport trolley 202 installed on the automatic transport device 200 is stopped. In addition, as described above, the transport trolley 202 installed on the automatic transport device 200 is electrically connected to the automatic transport device 200. Therefore, when the emergency stop switch 234a of the transport trolley 202 is operated, the operation signal of the emergency stop switch 234a is output from the transport trolley 202 to the automatic transport device 200. At this time, the automatic transport device 200 receives the operation signal of the emergency stop switch 234a of the transport trolley 202. This is because, when an abnormality occurs in the transport trolley 202 during the transport of the transport trolley 202 by the automatic transport device 200, it is necessary to stop the transport of the transport trolley 202 by the automatic transport device 200. In addition, when an abnormality occurs in the transport trolley 202 during the transfer of the storage rack 160 by the transport trolley 202, the transfer action of the storage rack 160 is stopped, but at this time, there is a problem in the transport of the transport trolley 202 by the automatic transport device 200. In addition, if the automatic transport device 200 receives an operation signal of the emergency stop switch 234a, the operation of the automatic transport device 200 is stopped urgently. That is, when the transport trolley 202 is moved by the operation of the automatic transport device 200, when the emergency stop switch 234a of the transport trolley 202 is operated, the operation of the automatic transport device 200 is also stopped urgently, and the movement of the transport trolley 202 is stopped. In this way, when the transport cart 202 is moved by the operation of the automatic transport device 200, by operating any one of the emergency stop switches 234a of the transport cart 202 and 220a of the automatic transport device 200, the operation of the automatic transport device 200 is urgently stopped and the movement of the transport cart 202 is stopped.

[0058] In addition, when transferring the storage rack 160 between the feeder storage warehouse 20 and the transport trolley 202, or between the transport trolley 202 and the rack management device 280, in the event of a malfunction or the like, the operator operates the emergency stop switch 234a of the transport trolley 202. As a result, the operation of the transport trolley 202 is urgently stopped, and the transfer of the storage rack 160 between the feeder storage warehouse 20 and the transport trolley 202, or between the transport trolley 202 and the rack management device 280 is stopped. However, when transferring the storage rack 160 between the feeder storage warehouse 20 and the transport trolley 202, or between the transport trolley 202 and the rack management device 280, even if the emergency stop switch 220a of the automatic transport device 200 is operated, the transfer of the storage rack 160 does not stop. In detail, the transport trolley 202 installed on the automatic transport device 200 is electrically connected to the automatic transport device 200. However, for example, the automatic transport device 200 only needs to be in a shape that can transport the transport trolley 202, so there is a case where the manufacturer of the automatic transport device 200 is different from the manufacturer of the transport trolley 202. In such a case, the output conditions of the emergency signal of the automatic transport device 200 may not be unified. In addition, in the case where an abnormality occurs in the automatic transport device 200 during the transport of the transport trolley 202 by the automatic transport device 200 other than the operation of the emergency stop switch 220a by the operator, the transport trolley 202 is transported only by the automatic transport device 200, and therefore, it is not necessary to receive the emergency stop signal from the automatic transport device 200. In addition, in the case where an abnormality occurs in the automatic transport device 200 during the transfer of the transport trolley 202 to the storage rack 160 other than the operation of the emergency stop switch 220a by the operator, the transport trolley 202 performs the transfer operation of the storage rack 160 without receiving the emergency stop signal from the automatic transport device 200 to the transport trolley 202, so as to prevent the transfer operation of the transport trolley 202 from being interrupted by the stop of the automatic transport device 200. For such reasons, even if the automatic transport device 200 is electrically connected to the transport trolley 202, the transport trolley 202 does not accept the emergency stop signal output from the automatic transport device 200. Therefore, when the storage rack 160 is transferred, even if the emergency stop switch 220a of the automatic transport device 200 is operated, the transfer of the storage rack 160 does not stop. That is, when the transport trolley 202 moves, the movement of the transport trolley 202 stops regardless of which of the emergency stop switch 234a of the transport trolley 202 and the emergency stop switch 220a of the automatic transport device 200 is operated, but when the storage rack 160 is transferred, if the emergency stop switch 234a of the transport trolley 202 is not operated, the transfer of the storage rack 160 does not stop.

[0059] In this way, when the transport trolley 202 is installed on the automatic transport device 200, since there are two emergency stop switches, namely the emergency stop switch 234a of the transport trolley 202 and the emergency stop switch 220a of the automatic transport device 200, the operator may be confused about which switch to operate in a sudden judgment. Therefore, it is also possible to consider removing the emergency stop switch 220a of the automatic transport device 200, but the automatic transport device 200 may move without the transport trolley 202 installed, so the emergency stop switch 220a of the automatic transport device 200 cannot be removed. In view of such a situation, in the transport trolley 202, a component is provided in the locking mechanism 260 to shield the emergency stop switch 220a of the automatic transport device 200 when the transport trolley 202 is installed on the automatic transport device 200.

[0060] Specifically, if Fig.12 as well as Fig.13 As shown, a pair of locking mechanisms 260 are provided at the side edge of the front side of the top plate 240 of the transport dolly 202 in a manner of sandwiching the cutout portion 244. The pair of locking mechanisms 260 each includes a slider 290, a limiting plate 292, and a stop screw 294. The slider 290 is provided on the top plate 240 in a manner of being able to slide in the left-right direction, and the slider 290 is fixed to the top plate 240 by the stop screw 294. In addition, the limiting plate 292 is a substantially rectangular plate shape, and is fixed to the slider 290 in a manner of extending in the left-right direction of the transport dolly 202 in the longitudinal direction. In addition, by sliding the slider 290 toward the cutout portion 244, the limiting plate 292 is fixed to the slider 290 in a manner of extending into the inside of the cutout portion 244. In addition, by sliding the slider 290 in a direction away from the cutout portion 244, the limiting plate 292 is fixed to the slider 290 in a manner of not extending into the inside of the cutout portion 244 but being hidden under the top plate 240. With such a structure, when the transport trolley 202 is mounted on the automatic transport device 200, the sliders 290 of the pair of locking mechanisms 260 slide toward the cutout portion 244, thereby Fig.13 As shown, the pair of limiting plates 292 are located in front of the pair of front side pins 222 at the corners of the cutout portion 244. Furthermore, the slider 290 is fixed to the top plate 240 by the stop screw 294, so that the movement of the pair of front side pins 222 to the front side is limited by the pair of limiting plates 292. Thus, the transport trolley 202 mounted on the automatic transport device 200 is locked by the pair of locking mechanisms 260. In addition, by loosening the stop screw 294, the pair of sliders 290 are slid in the direction away from the cutout portion 244, as shown in FIG. Fig.12 As shown, the pair of restriction plates 292 moves from the front of the pair of front side pins 222 to the lower side of the top plate 240. As a result, the lock of the transport cart 202 to the automatic transport device 200 is released.

[0061] In addition, in the pair of locking mechanisms 260, Fig.12 and Fig.13 The left locking mechanism 260a in FIG. 2 is provided with a shielding member 300 for shielding the emergency stop switch 220a of the automatic transport device 200. Specifically, the locking mechanism 260a is shown from the viewpoint below the top plate 240. Fig.14 As shown, the shielding member 300 is in a substantially L-shaped plate shape, and is fixed to the limiting plate 292 in a substantially U-shaped manner. The shielding member 300 is fixed to the limiting plate 292 in a manner such that the front side pin 222a is located between the limiting plate 292 and the shielding member 300. In addition, the front end of the shielding member 300 extends from the front end of the limiting plate 292 to the inside of the cutout portion 244 of the top plate 240. In addition, the end portion of the front side of the front end of the shielding member 300 is bent downwardly at a substantially right angle to form a lower bent portion 302. The lower bent portion 302 is also bent rearwardly at a substantially right angle on the base end side of the shielding member 300 to form a rear bent portion 304.

[0062] Through such a construction, Fig.13 As shown, when the slider 290 of the locking mechanism 260a slides toward the cutout 244 and the limiting plate 292 moves forward of the front side pin 222a, the shielding member 300 moves toward the cutout 244 in conjunction with the locking mechanism 260a. At this time, the lower curved portion 302 of the shielding member 300 is located in front of the emergency stop switch 220a of the automatic transport device 200, and the rear curved portion 304 of the shielding member 300 is located on the left side of the emergency stop switch 220a of the automatic transport device 200. Thus, the front side and the left side of the emergency stop switch 220a of the automatic transport device 200 are shielded by the lower curved portion 302 and the rear curved portion 304 of the shielding member 300. In addition, the top of the emergency stop switch 220a of the automatic transport device 200 is covered by the top plate 240. In addition, an L-shaped bracket 308 is fixed to the top plate 240 in a manner extending toward the right side of the emergency stop switch 220a of the automatic transport device 200. As a result, the upper side of the emergency stop switch 220a of the automatic transport device 200 is shielded by the top plate 240, and the right side of the emergency stop switch 220a of the automatic transport device 200 is shielded by the bracket 308. In this way, the shielding member 300 and the locking mechanism 260a move in conjunction with each other, and when the locking mechanism 260a locks the transport trolley 202, the entire emergency stop switch 220a is shielded by the shielding member 300, the top plate 240, and the bracket 308.

[0063] On the other hand, Fig.12As shown, when the slider 290 of the locking mechanism 260a slides in a direction away from the cutout portion 244 and the limiting plate 292 moves from the front side pin 222a to the bottom of the top plate 240, the shielding member 300 also moves in a direction away from the emergency stop switch 220a in conjunction with the locking mechanism 260a. At this time, the lower curved portion 302 of the shielding member 300 moves from the front side of the emergency stop switch 220a, and the rear curved portion 304 of the shielding member 300 moves from the left side of the emergency stop switch 220a. As a result, the front side and the left side of the emergency stop switch 220a of the automatic handling device 200 are exposed. In this way, when the transport trolley 202 is installed on the automatic handling device 200 and locked, the entire emergency stop switch 220a is shielded. Therefore, the operator cannot recognize the emergency stop switch 220a of the automatic transport device 200 and the transport trolley 202 installed on the automatic transport device 200 and locked, and can only recognize the emergency stop switch 234a of the transport trolley 202. As a result, the operator can operate the emergency stop switch 234a of the transport trolley 202 without being confused in an emergency.

[0064] In addition, in the pair of locking mechanisms 260, Fig.12 as well as Fig.13 The locking mechanism 260b on the right side of the embodiment is provided with a component for electrically connecting the automatic transport device 200 to the transport trolley 202. Fig.15 As shown in the figure, a support plate 310 is fixed to the limiting plate 292 of the locking mechanism 260b in a manner extending toward the rear. Moreover, a connector 312 is fixed to the front end of the support plate 310 in a posture extending toward the cutout portion 244 of the top plate 240. On the other hand, a connector connecting member 316 is arranged on the right side of the front side pin 222b on the top plate 216 of the automatic transport device 200. The connector connecting member 316 is opposite to the connector 312 fixed to the limiting plate 292 of the locking mechanism 260b via the support plate 310, and a connecting portion 318 corresponding to the shape of the connector 312 is formed at a position opposite to the connector 312.

[0065] In such a structure, Fig.15 As shown, when the slide member 290 of the locking mechanism 260b slides in a direction away from the notch 244 and the limiting plate 292 is located below the top plate 240, the connector 312 is opposed to the connection portion 318 of the connector connection component 316 of the automatic transport device 200 and is not connected to the connection portion 318. That is, when the transport trolley 202 is installed on the automatic transport device 200 but is not locked, the connector 312 of the transport trolley 202 is not connected to the connector connection component 316 of the automatic transport device 200, and the automatic transport device 200 and the transport trolley 202 are not electrically connected. Furthermore, as Fig.16As shown, when the slider 290 of the locking mechanism 260b slides toward the cutout portion 244 and the limiting plate 292 moves forward of the front side pin 222b, the connector 312 also moves toward the front side pin 222 in conjunction with the locking mechanism 260a. At this time, the connector 312 of the transport trolley 202 is engaged with the connecting portion 318 of the automatic transport device 200 and connected to the connector connecting member 316. That is, when the transport trolley 202 is mounted on the automatic transport device 200 and locked, the connector 312 of the transport trolley 202 is connected to the connector connecting member 316 of the automatic transport device 200, so that the automatic transport device 200 and the transport trolley 202 are electrically connected.

[0066] In this way, when the transport trolley 202 is installed on the automatic transport device 200 and locked, the automatic transport device 200 is electrically connected to the transport trolley 202, so that the operation of the emergency stop switch 234a of the transport trolley 202 can be ensured. In detail, as described above, the automatic transport device 200 is electrically connected to the transport trolley 202, and when the emergency stop switch 234a of the transport trolley 202 is operated, the operation signal of the emergency stop switch 234a is output from the transport trolley 202 to the automatic transport device 200. And, if the automatic transport device 200 receives the operation signal of the emergency stop switch 234a, the operation of the automatic transport device 200 stops urgently. Therefore, when the automatic transport device 200 is not electrically connected to the transport trolley 202, even if the emergency stop switch 234a of the transport trolley 202 is operated, the operation of the automatic transport device 200 does not stop. In particular, when the emergency stop switch 220a of the automatic transport device 200 is shielded by the shielding member 300, the emergency stop switch 220a cannot be operated, and thus the operation of the automatic transport device 200 cannot be stopped. In view of such a situation, the connector 312 of the transport trolley 202 is provided on the locking mechanism 260b, and the transport trolley 202 is locked to the automatic transport device 200 by the locking mechanism 260b, so that the connector 312 of the transport trolley 202 is necessarily connected to the connector connection member 316 of the automatic transport device 200. Thus, when the transport trolley 202 is locked to the automatic transport device 200 by the locking mechanism 260b, the automatic transport device 200 and the transport trolley 202 are necessarily electrically connected, so that the operation of the emergency stop switch 234a of the transport trolley 202 is reliably ensured.

[0067] In addition, in the above-mentioned embodiment, the automatic transport device 200 is an example of an automatic transport device. The transport cart 202 is an example of an installation device. The emergency stop switch 220a is an example of a component. The emergency stop switch 234a is an example of an installation device side operation switch. The top plate 240 is an example of a shielding member. The locking mechanism 260 is an example of a locking mechanism. The shielding member 300 is an example of a shielding member. The bracket 308 is an example of a shielding member. The connector 312 is an example of a connecting member.

[0068] As described above, in the present embodiment described above, the following effects are achieved.

[0069] In the transport cart 202 installed in the automatic transport device 200, the emergency stop switch 220a of the automatic transport device 200 is shielded by the shielding member 300, the top plate 240, and the bracket 308. Thus, when the transport cart 202 is installed in the automatic transport device 200, for example, the emergency stop switch 220a that may confuse the operator's operation can be hidden.

[0070] In addition, the shielding member 300 moves between a position for shielding the emergency stop switch 220a of the automatic transport device 200 and a position for exposing the emergency stop switch 220a when attached to the automatic transport device 200. Thus, shielding and exposure of the emergency stop switch 220a can be arbitrarily changed.

[0071] In addition, the shielding member 300 moves in conjunction with the locking mechanism 260a, and shields the emergency stop switch 220a of the automatic transport device 200 when the locking mechanism 260a locks the transport trolley 202. Thus, the transport trolley 202 is locked to the automatic transport device 200 by the locking mechanism 260a without intentionally moving the shielding member 300, so that the emergency stop switch 220a can be shielded by the shielding member 300.

[0072] In addition, the transport cart 202 is provided with a connector 312 electrically connected to the automatic transport device 200. The connector 312 moves in conjunction with the locking mechanism 260b, and is connected to the connector connection member 316 of the automatic transport device 200 when the locking mechanism 260b locks the transport cart 202. Thus, the operator does not forget the connection between the connector 312 and the connector connection member 316, and can reliably electrically connect the automatic transport device 200 and the transport cart 202.

[0073] In addition, the emergency stop switch 220a of the automatic transport device 200 is a switch for emergency stopping the operation of the automatic transport device 200, and the transport trolley 202 is also provided with an emergency stop switch 234a for emergency stopping the operation of the automatic transport device 200. Thus, even when the emergency stop switch 220a of the automatic transport device 200 is shielded by the shielding member 300, the operation of the automatic transport device 200 can be emergency stopped by operating the emergency stop switch 234a of the transport trolley 202.

[0074] In addition, the present disclosure is not limited to the above-mentioned embodiments, and can be implemented in various ways with various changes and improvements based on the knowledge of those skilled in the art. Specifically, for example, in the above-mentioned embodiments, the transport trolley 202 has casters 248, and is configured to travel together with the automatic transport device 200 when installed on the automatic transport device 200. On the other hand, as an installation device installed on the automatic transport device 200, it can also be a device that does not have wheels and is installed on the automatic transport device 200 and transported by the operation of the automatic transport device 200. In addition, the installation device can be installed in a state of being placed on the upper surface of the automatic transport device 200, and can also be installed in a state of being hooked on the side of the automatic transport device 200.

[0075] In addition, in the above-mentioned embodiment, the emergency stop switch 220a is shielded by the shielding member 300, the top plate 240 and the bracket 308, but it is also possible to shield the emergency stop switch 220a by the top plate 240 and the bracket 308 without using the shielding member 300. That is, the emergency stop switch 220a may be shielded by the top plate 240 and the bracket 308 which are fixed and immovable instead of the movable shielding member 300. In addition, the emergency stop switch 220a may be shielded by the shielding member 300 instead of the top plate 240 and the bracket 308. That is, the emergency stop switch 220a may be shielded by the movable shielding member 300 instead of the fixed top plate 240 and the bracket 308.

[0076] In addition, in the above-mentioned embodiment, the shielding member 300 is used in conjunction with the locking mechanism 260a, but the shielding member 300 may be used without being in conjunction with the locking mechanism 260a. That is, the shielding member 300 may be simply slid between the shielding position and the exposure position of the emergency stop switch 220a without being fixed to the limiting plate 292 of the locking mechanism 260a.

[0077] In addition, in the above embodiment, the emergency stop switch 220a is shielded by the shielding member 300, but it is not limited to the emergency stop switch 220a. The operating switch that enables the automatic transport device 200 to perform predetermined tasks, such as mode switching, light lighting, etc., may also be shielded by the shielding member 300.

[0078] In the above embodiment, the emergency stop switch 220a is shielded by the shielding member 300, but the display monitor 218 may be shielded. In such a case, it is preferable to provide a display monitor for displaying the operating state of the automatic transport device 200 on the transport cart 202.

[0079] In addition, in the above-mentioned embodiment, the locking mechanism 260 is provided on the transport trolley 202, but it may also be provided on the automatic transport device 200. In this way, when the locking mechanism 260 is provided on the automatic transport device 200, as the locking mechanism 260 slides, etc., the locking mechanism 260 contacts the shielding member provided on the transport trolley 202, so that the shielding member and the locking mechanism 260 move in conjunction with each other.

[0080] In addition, in the above-mentioned embodiment, the storage rack 160 storing the tape feeder 90 is transported by the transport trolley 202, but the present invention is not limited to the storage rack 160, and various storage racks may be transported by the transport trolley 202. Specifically, for example, a tray cassette storing a tray for mounting components, a mask cassette storing a mask used for solder printing, a substrate cassette storing a substrate, etc. may be transported by the transport trolley 202.
