The upper magazine and the lower magazine are movable up and down, and the pallet extraction mechanism supplies components by adjusting the height of the pallet to be extracted among the upper magazine and the lower magazine to the extraction height and extracting the pallet to the component supply position.
[0003] Japanese Patent Application Laid-Open No. 2023-160449
[0004] In order to accommodate a large number of pallets, when a pallet storage section capable of stocking replenishment pallets is installed in a tray unit for the upper magazine and the lower magazine, the pallet storage section must be installed avoiding the lifting range of the two magazines. For this reason, it is difficult to secure sufficient space, leading to an increase in the size of the device or a shortage in the number of pallets that can be accommodated.
[0005] The main object of the present disclosure is to provide a component supply device capable of accommodating a large number of pallets without increasing the size of the device.
[0006] The present disclosure has adopted the following means to achieve the above main object.
[0007] The component supply device of the present disclosure mainly includes a production magazine having a plurality of slots capable of accommodating pallets that hold trays in which a plurality of components are accommodated, a pallet transfer mechanism capable of transferring the pallet between the plurality of slots of the production magazine and the component supply position of a component mounter, a storage section installed so as to be vertically aligned with the production magazine and incapable of transferring the pallet by the pallet transfer mechanism and capable of accommodating a plurality of the pallets, and a pallet replacement mechanism for replacing the pallet between a plurality of pallet storage sections including the production magazine and the storage section.
[0008] The parts supply device of this disclosure includes a production magazine installed to allow pallets to be transferred to the parts supply position by a pallet transfer mechanism, and a storage section installed vertically alongside the production magazine and in which pallets cannot be transferred by the pallet transfer mechanism. This allows for a larger storage space compared to a parts supply device with two vertically movable production magazines. As a result, a large number of pallets can be accommodated without increasing the size of the device.

Figure 5 is a top view of the internal configuration of the parts supply device 10. Figure 6 is an external perspective view of the pallet exchange mechanism 50. Figure 7 is an external perspective view of the pallet PT that holds the tray TY containing multiple parts P. In Figures 1 to 7, the left-right direction is the X direction, the front-back direction is the Y direction, and the up-down direction is the Z direction.
[0012] As shown in Figures 1 and 2, the component supply device 10 of this embodiment is detachably mounted on the front of the component mounting machine 1 and supplies components PA to the component mounting machine 1 by transporting a pallet PT (see Figure 7) that holds a tray TY containing multiple components P to the component supply position. The component mounting machine 1 takes the components PA from the pallet PT supplied to the component supply position and mounts them on a substrate. In addition to a head 2 having a suction nozzle capable of picking up components PA, it is equipped with a head moving device for moving the head 2, a substrate transport device for transporting the substrate, and a parts camera that takes an image of the suction nozzle to check the suction state of the components PA after the suction operation of the suction nozzle has been performed on the components PA.
[0013] As shown in Figures 1 to 6, the parts supply device 10 includes a housing 11, a production magazine 21, a replenishment magazine 31, a storage compartment 41, a second storage compartment 42, a pallet exchange mechanism 50 having a shuttle 51, a pallet transfer mechanism 70 having a shuttle 71, and a control device (not shown) that controls the entire device.
[0014] As shown in Figures 1 and 2, the housing 11 is a roughly rectangular box-shaped body that covers the production magazine 21, the supply magazine 31, the storage compartment 41, the second storage compartment 42, and the pallet exchange mechanism 50. A supply door 12 and an inspection door 13 are installed vertically on the upper left front of the housing 11. The supply door 12 and the inspection door 13 are each attached to an opening 11o formed on the upper left front of the housing 11 via hinges H so as to be able to be opened and closed, and can be locked and unlocked by an electric locking device (not shown). In this embodiment, the supply door 12 and the inspection door 13 are attached to the left frame of the opening 11o via hinges H, but they may also be attached to the right frame, lower frame, or upper frame via hinges. In this embodiment, transparent windows are fitted into the supply door 12 and the inspection door 13, allowing the operator to see the inside through the transparent windows.
[0015] Furthermore, a display device 15 is installed on the upper right of the front of the housing 11. The display device 15 is configured as a touch panel display device that displays various information to notify the operator, such as work instruction information and error information, and also allows the operator to input various operations.
[0016] As shown in Figure 4, the production magazine 21 is a roughly rectangular box-shaped body with openings at the front and rear, and has multiple slots S arranged vertically. Each slot S accommodates a pallet PT so that it can be inserted and removed from both the front and rear sides. As shown in Figure 7, the pallet PT holds trays TY, each containing parts PA, in multiple storage recesses arranged in a grid pattern. Furthermore, roughly T-shaped notches NT are formed at both ends of the pallet TP in the front and rear direction, which are engaged at the front and rear by pallet pull-out mechanisms 60 and 80, respectively, which will be described later.
[0017] As shown in Figure 4, the production magazine 21 is located on the rear right side of the internal space of the housing 11. The production magazine 21 is supported so as to be able to move up and down on a guide rail 23 that extends vertically. The production magazine 21 is moved up and down within the internal space of the housing 11 by a lifting device 25. The lifting device 25 moves the production magazine 21 up and down so that the pallet PT to be pulled out is at a height that can be pulled out by the pallet pull-out mechanism 80 of the pallet transfer mechanism 70. In this embodiment, the lifting device 25 is configured as a ball screw mechanism, but it may also be configured as a linear motor.
[0018] As shown in Figure 4, the supply magazine 31 is a roughly rectangular box-shaped body with an open front and has multiple slots S arranged vertically. Each slot S accommodates a pallet PT so that it can be inserted and removed from the front. The supply magazine 31 is located at the uppermost position on the rear left side of the internal space of the housing 11. The supply magazine 31 is supported so as to be slidable back and forth on a guide rail 32 that extends in the front and rear directions. The supply magazine 31 is moved back and forth within the internal space of the housing 11 by a front-to-back movement device 33. In this embodiment, the front-to-back movement device 33 is configured as a belt drive mechanism, but it may also be configured as a ball screw mechanism or a linear motor. A supply door 12 is provided on the front of the housing 11 so as to face the supply magazine 31 from the front and rear. Therefore, the operator can insert and remove pallets PT into and out of the supply magazine 31 by opening the supply door 12 when the supply magazine 31 has moved forward (towards the operator).
[0019] As shown in Figure 4, the storage unit 41 and the second storage unit 42 are roughly rectangular box-shaped bodies with an open front, and each has multiple slots S arranged vertically. Each slot S accommodates a pallet PT so that it can be inserted and removed from the front. The storage unit 41 has an upper storage section 41a and a lower storage section 41b, which are installed in the rear right side of the internal space of the housing 11, aligned vertically with the production magazine 21, and are not movable vertically, so as to avoid the vertical movement range of the production magazine 21. The upper storage section 41a is installed above the production magazine 21 at a height slightly higher than the upper end of the vertical movement range of the production magazine 21. The lower storage section 41b is installed below the production magazine 21 at a height slightly lower than the lower end of the vertical movement range of the production magazine 21. As a result, the storage unit 41 can have a large number of slots S and accommodate a large number of pallet PTs. Note that the storage unit 41 may have only one of the upper storage section 41a and the lower storage section 41b. The second storage compartment 42 is installed in the rear left side of the internal space of the housing 11, below the supply magazine 31, and is not movable up or down. Parts of the storage compartment 41 and the second storage compartment 42 may be detachable from the housing 11 and configured to be loaded into and out of the device by an automated guided vehicle (not shown).
[0020] As shown in Figure 3, the pallet exchange mechanism 50 moves within the internal space of the housing 11, facing the production magazine 21, the supply magazine 31, the storage compartment 41, and the second storage compartment 42 (movable range), to exchange pallets PT between them. As shown in Figures 5 and 6, the pallet exchange mechanism 50 includes a shuttle 51, a lifting table 52, a lifting device 55, a left-right movement device 56, a pallet pull-out mechanism 60, and a clamper drive device 65.
[0021] As shown in Figure 3, the lifting table 52 is supported so as to be able to move up and down by guide rails 54 installed on the left and right side walls of the housing 11 so as to extend vertically. The lifting table 52 is raised and lowered by a lifting device 55. In this embodiment, the lifting device 55 is configured as a ball screw mechanism, but it may also be configured as a linear motor.
[0022] The shuttle 51 is used to place the pallet PT, and as shown in Figures 5 and 6, it is supported so as to be slidable from side to side by guide rails 53 that extend horizontally from the upper surface of the lifting table 52. The shuttle 51 is moved from side to side by a left-right movement device 56. Thus, the shuttle 51 is moved up, down, left, and right by the lifting device 55 and the left-right movement device 56. In this embodiment, the left-right movement device 56 is configured as a belt drive mechanism, but it may also be configured as a ball screw mechanism or a linear motor.
[0023] The pallet pulling mechanism 60 is mounted on the shuttle 51 and pulls out pallets PT from the production magazine 21, supply magazine 31, storage compartment 41, and second storage compartment 42 and places them on the shuttle 51, or feeds the pallets PT on the shuttle 51 into the production magazine 21, supply magazine 31, storage compartment 41, and second storage compartment 42. As shown in Figures 5 and 6, the pallet pulling mechanism 60 has a pair of left and right belts 61 extending in the front and rear directions, a slider 62 extending in the left and right directions and stretched across the pair of belts 61, a belt drive device 63 that drives the pair of belts 61, a pair of left and right clampers 64 provided in the left and right center of the slider 62, and a clamper drive device 65 that expands and contracts the pair of clampers 64. As described above, T-shaped notches NT are formed at both ends of the pallet PT in the front and rear directions. The pallet pulling mechanism 60 inserts the pair of clampers 64 into the notches NT on the front of the pallet PT by bringing the slider 62 close to the pallet PT with the pair of clampers 64 retracted, and then clamps the pallet PT by expanding the pair of clampers 64. Then, with the pallet PT clamped, the pallet pulling mechanism 60 moves the slider 62 forward (towards the front) to pull the pallet PT forward and place it on the shuttle 51. The clamper drive device 65 is, for example, an air cylinder and is located at the rear of the shuttle 51. The clamper drive device 65 can supply and discharge air to the pair of clampers 64 when the pair of clampers 64 are close to the rear of the shuttle 51, i.e., close to the production magazine 21, the supply magazine 31, the storage compartment 41, and the second storage compartment 42, and can clamp the pallets PT stored in each magazine.
[0024] The pallet transfer mechanism 70 pulls out pallet PTs that are at a pull-out height from among the pallet PTs stored in the production magazine 21 and supplies them to the parts supply position, or feeds pallet PTs from the parts supply position into empty slots S of the production magazine 21 that are at a feedable height. The pallet transfer mechanism 70 includes a shuttle 71 and a pallet pull-out mechanism 80 mounted on the shuttle 71. The pallet pull-out mechanism 80 is configured in the same way as the pallet pull-out mechanism 60. That is, the pallet pull-out mechanism 80 inserts a pair of clampers in a retracted state into the notch NT on the rear side of the pallet PT, and then clamps the pallet PT by expanding the pair of clampers. Then, with the pallet PT clamped, the pallet pull-out mechanism 80 moves a slider to the rear (back) to pull the pallet PT to the rear and place it on the shuttle 71.
[0025] Next, the operation of the component supply device 10 configured in this way will be described.
[0026] The control device of the parts supply device 10 first raises and lowers the production magazine 21 using the lifting device 25 to adjust the height of the pallet PT (target pallet) to be supplied, which is stored in one of the slots S of the production magazine 21, to a height that can be pulled out by the pallet pull-out mechanism 80 of the pallet transfer mechanism 70. Next, the control device uses the pallet pull-out mechanism 80 to pull out the target pallet from the production magazine 21 and supply it to the parts supply position. The parts mounting machine 1 takes out the parts PA from the target pallet supplied to the parts supply position and mounts them on the circuit board. After the parts mounting machine 1 has taken out the required number of parts PA from the target pallet, the control device uses the pallet pull-out mechanism 80 to send the target pallet on the parts supply position into an empty slot S of the production magazine 21. By repeating these operations, the control device sequentially selects pallets PT loaded with the necessary parts PA for production and supplies them to the parts supply position.
[0027] Furthermore, if a suction error occurs with respect to a component PA mounted on a pallet PT, and it becomes necessary for an operator to check the status of the pallet PT (target pallet) on which the component PA was mounted, the control device of the component mounting machine 1 performs the following control. First, the control device displays work instruction information on the display device 15 instructing the operator to check the status of the target pallet. Next, the control device uses the pallet withdrawal mechanism 80 to feed the target pallet at the component supply position into an empty slot S of the production magazine 21. Next, the control device uses the lifting device 55 and left / right movement device 56 of the pallet exchange mechanism 50 to move the shuttle 51 in front of the target pallet in the production magazine 21, and uses the pallet withdrawal mechanism 60 to pull the target pallet out of the production magazine 21 and place it on the shuttle 51. Then, the control device uses the lifting device 55 and left / right movement device 56 of the pallet exchange mechanism 50 to move the shuttle 51 with the target pallet on it to the front of the inspection door 13 and unlock the inspection door 13. As a result, the operator can visually check the target pallet on the shuttle 51 by opening the inspection door 13. The worker checks, for example, whether the tray TY is held in the correct orientation on the pallet PT, and whether the parts PA have come out of the tray TY, and makes any necessary corrections if there are any abnormalities.
[0028] Next, the operation of the pallet exchange mechanism 50 when exchanging pallet PTs between the production magazine 21, the supply magazine 31, the storage 41, and the second storage 42 will be explained. The pallet exchange mechanism 50 moves the shuttle 51 in a space facing the production magazine 21, the supply magazine 31, the storage 41, and the second storage 42 in a front-to-back direction, pulls a pallet PT from one of the magazines onto the shuttle 51, and sends it into an empty slot S of another magazine, thereby exchanging pallet PTs.
[0029] First, the control device uses the lifting device 55 and left / right movement device 56 of the pallet exchange mechanism 50 to move the shuttle 51 in front of the pallet PT (target pallet) to be exchanged, which is stored in the magazine from which it is being exchanged. Next, the control device uses the pallet pull-out mechanism 60 to pull out the target pallet from the magazine from which it is being exchanged and place it on the shuttle 51. Then, the control device uses the lifting device 55 and left / right movement device 56 of the pallet exchange mechanism 50 to move the shuttle 51 with the target pallet on it in front of an empty slot S in the magazine to which it is being exchanged. Finally, the control device uses the pallet pull-out mechanism 60 to feed the target pallet into the empty slot S of the magazine to which it is being exchanged. The parts supply device 10 stores pallets PT loaded with parts PA necessary for the next production in the storage room 41 or the second storage room 42, and can exchange the pallets PT from the storage room 41 or the second storage room 42 into the production magazine 21 and supply them to the parts supply position at the required timing. Furthermore, the parts supply device 10 can recover used pallet PTs by transferring them from the production magazine 21 to the replenishment magazine 31, storage unit 41, or second storage unit 42. As described above, the storage unit 41 has an upper storage unit 41a and a lower storage unit 41b that are installed so as not to move up or down, avoiding the lifting range of the production magazine 21, so that a large number of pallet PTs can be stored without increasing the size of the housing 11. As a result, the operator does not need to frequently replenish the parts supply device 10 (replenishment magazine 31) with pallet PTs to be used or recover used pallet PTs, thereby reducing the workload.
[0030] Here, the correspondence between the main elements of this embodiment and the main elements of the present disclosure will be explained. Specifically, the production magazine 21 of this embodiment is an example of a production magazine of the present disclosure, the pallet transfer mechanism 70 is an example of a pallet transfer mechanism, the storage unit 41 is an example of a storage unit, and the pallet exchange mechanism 50 is an example of a pallet exchange mechanism. The lifting device 25 is an example of a magazine lifting mechanism. The upper storage unit 41a of the storage unit 41 is an example of an upper storage unit, and the lower storage unit 41b of the storage unit 41 is an example of a lower storage unit. The replenishment magazine 31 is an example of a replenishment magazine, the second storage unit 42 is an example of a second storage unit, and the shuttle 51 is an example of a replacement shuttle.
[0031] It goes without saying that this disclosure is not limited in any way to the embodiments described above, and can be implemented in various forms as long as they fall within the technical scope of this disclosure.
[0032] For example, in the embodiment described above, the production magazine 21 is installed so as to be able to move up and down within the housing 11, but it may also be installed so as not to move up and down. Figure 9 is a schematic diagram of the parts supply device 110 according to another embodiment. As shown in Figure 9, the parts supply device 110 according to the other embodiment includes a production magazine 121 installed so as not to move up and down within the housing 11 and having a plurality of slots S arranged vertically, a storage compartment 141 installed so as not to move up and down within the housing 11, and a pallet transfer mechanism 170. The pallet transfer mechanism 170 includes a shuttle 171, a lifting device 172 for raising and lowering the shuttle 171, and a pallet pull-out mechanism 180 mounted on the shuttle 171. The lifting device 172 is configured, for example, by a ball screw mechanism or a linear motor. The pallet pull-out mechanism 180 is configured in the same way as the pallet pull-out mechanism 80 described above. The pallet transfer mechanism 170 uses a lifting device 172 to raise and lower the shuttle 171 so that the pallet withdrawal mechanism 180 is at a height facing the target slot of the production magazine 121, thereby allowing the pallet withdrawal mechanism 80 to insert and remove the pallet PT into and out of the target slot. The storage compartment 141 has multiple slots S arranged vertically and includes an upper storage compartment 141a and a lower storage compartment 141b that are installed vertically alongside the production magazine 121, avoiding the lifting range of the shuttle 171. The upper storage compartment 141a is installed above the production magazine 121 at a height slightly higher than the upper end of the lifting range of the shuttle 171. The lower storage compartment 141b is installed below the production magazine 121 at a height slightly lower than the lower end of the lifting range of the shuttle 171. This allows the pallet PT to be moved between any slot S of the production magazine 21 and the parts supply position by raising and lowering the shuttle 171, and also allows the storage unit 141 having multiple slots S to be arranged without obstructing the raising and lowering of the shuttle 171. Note that the storage unit 141 may have only one of the upper storage unit 141a and the lower storage unit 141b.
[0033] Furthermore, in the above-described embodiment, the parts supply device 20 is provided with a production magazine 21, a replenishment magazine 31, a storage compartment 41, and a second storage compartment 42 within the housing 11, but the replenishment magazine 31 and the second storage compartment 42 may be omitted. In this case, the parts supply device 20 may be configured to allow pallets PT to be directly inserted into and removed from the production magazine 21 and the storage compartment 41.
[0034] As described above, the parts supply device of this disclosure includes a production magazine installed to allow pallets to be transferred to the parts supply position by a pallet transfer mechanism, and a storage section installed vertically alongside the production magazine and in which pallets cannot be transferred by the pallet transfer mechanism. This allows for a larger storage space compared to a parts supply device equipped with two vertically movable production magazines. As a result, it is possible to accommodate a large number of pallets without increasing the size of the device.
[0035] In the parts supply device of the present disclosure, the device further comprises a magazine lifting mechanism for raising and lowering the production magazine, and the pallet transfer mechanism is capable of transferring the pallet between a slot at a predetermined height among the plurality of slots of the production magazine and the parts supply position, accompanied by the raising and lowering of the production magazine, and the storage section may be installed to avoid the lifting and lowering range of the production magazine. In this way, the pallet can be transferred between any slot of the production magazine and the parts supply position by raising and lowering the production magazine, and the storage section can be positioned without hindering the lifting and lowering of the production magazine. In this case, the storage section may have an upper storage section installed above the lifting and lowering range of the production magazine and not capable of moving up or down, and a lower storage section installed below the lifting and lowering range of the production magazine and not capable of moving up or down. By arranging the storage section as an upper storage section and a lower storage section, a larger number of pallets can be accommodated.
[0036] Alternatively, in the parts supply device of the present disclosure, the pallet transfer mechanism comprises a transfer shuttle on which the pallet can be placed and a shuttle lifting mechanism for raising and lowering the transfer shuttle, and the pallet can be transferred between the plurality of slots of the production magazine and the parts supply position by raising and lowering the transfer shuttle, and the storage unit may be installed so as to avoid the range of raising and lowering the transfer shuttle. In this way, the pallet can be transferred between any slot of the production magazine and the parts supply position by raising and lowering the transfer shuttle, and the storage unit can be positioned without obstructing the raising and lowering of the transfer shuttle.
[0037] Furthermore, in the parts supply device of this disclosure, the plurality of pallet storage sections include a supply magazine arranged to the left and right of the production magazine and the storage section and capable of supplying the pallets, and a second storage section arranged vertically of the supply magazine and capable of accommodating a plurality of the pallets, and the pallet exchange mechanism has an exchange shuttle that can move in a space facing the production magazine, the storage section, the second storage section and the supply magazine in the front and back directions, and the pallets may be exchanged between the production magazine, the storage section, the second storage section and the supply magazine by placing the pallets on the exchange shuttle and transporting them. In this way, pallets supplied to the supply magazine can be stored in the storage section and the second storage section. Furthermore, by providing the second storage section, a larger number of pallets can be stored.
[0038] This disclosure can be used in industries such as the manufacturing of parts supply equipment.
