Therefore, it cannot be understood as a limitation on the present invention. The directional terms of the present invention should be understood in conjunction with the actual installation status.

[0036] The present invention provides a buffer delivery system, see Figure 1As a specific embodiment of the buffer conveying system of the present invention, it includes a lane placement area 200, a set matching plate area 300 and a set buffer area 400. The lane placement area 200 is arranged with multiple partition lanes in sequence, and the multiple partition lanes respectively correspond to the storage of the transferred workpieces to be matched. The set matching plate area 300 is arranged corresponding to the lane placement area 200. The set matching plate area 300 is provided with a sorting and matching plate robot 5 that can sort the workpieces to be matched transferred from multiple partition lanes in sequence to form a set of workpieces. The set buffer area 400 corresponds to the set matching plate area 3 00 is arranged so that the complete sets of workpieces in the complete set matching area 300 can be transferred to the complete set buffer area 400 for storage, and the workpieces are installed and transferred by transfer carriers, wherein the transfer carriers include a first transfer carrier 1 for installing and transferring the workpieces to be matched and a second transfer carrier 2 for installing and transferring the complete sets of workpieces, wherein the first transfer carrier 1 can be transferred back and forth between the lane placement area 200 and the complete set matching area 300 in turn, and the second transfer carrier 2 can be transferred back and forth between the complete set matching area 300 and the complete set buffer area 400 in turn.

[0037] Taking the assembly of the scissor arm fork plate as an example, the scissor arm includes an outer fork frame and an inner fork frame, and the separate outer fork frame and the inner fork frame are respectively installed on different first transfer carriers 1 for shipment, and each separate outer fork frame or inner fork frame is transported to the lane placement area 200 by its corresponding first transfer carrier 1, and stored in the corresponding partition lane according to the set order, and the separate fork frames that need to be matched are sorted in advance through the partition lane, and are transported to the complete set of matching area 300 in this order by the first transfer carrier 1, so that the sorting and matching robot 5 in the complete set of matching area 300 can directly sort the separate fork arms in order for matching to form a complete set of fork arms, and the complete set of fork arms is transferred from the complete set of matching area 300 to the complete set of matching area 300 through the second transfer carrier 2. The second transfer vehicle 2 is transported to the complete set buffer area 400 for storage, and after being released from the complete set buffer area 400, it can return to the complete set matching area 300 to reinstall and transfer the complete set of fork arms with new matching pallets. The empty first transfer vehicle 1 left after the complete set matching area 300 completes the sorting of matching pallets and returns to install the new individual fork frame to be matched, and transfers it to the lane placement area 200 again, so as to form two logistics circulation systems, one is the logistics circulation from the individual fork frame to the matching pallet, and the other is the logistics circulation of the complete set matching pallet, storage and delivery. It has a high degree of automation, fast and orderly logistics, high flow efficiency, automatic matching, reduced labor intensity of personnel, and greatly improved productivity. At the same time, in the actual production process, the cache conveying system of the present invention will be connected to the individual fork arm coating line and the complete fork arm assembly line respectively. When the line speed of the production line does not match, the complete set cache area 400 can cache the complete set of fork arms to avoid accumulation. Even if the product is quickly changed, there is no need to repeatedly turn the fork to make room, thereby ensuring the orderly progress of logistics.

[0038] See also Figure 1 As a specific embodiment of the conveying cache system of the present invention, the cache conveying system of the present invention also includes a workpiece cache area 100 for storing workpieces to be matched and a sub-assembly line material distribution area 500 for component assembly, wherein the individual fork racks to be matched can be placed in the workpiece cache area 100 for cache. Therefore, when the production line speeds between the individual fork arm coating line, the cache conveying system of the present invention and the complete set of fork arms do not match, in addition to the complete set of fork arms 400 being able to cache the complete set of fork arms, the workpiece cache area 100 can also cache and store the individual fork arms that have been painted. The setting of the dual cache areas enables the cache conveying system of the present invention to have good adjustment capabilities for different production line speeds. The first transfer carrier 1 can be transported back and forth between the workpiece buffer area 100, the lane placement area 200 and the complete set of pallet area 300 in sequence. When production is carried out, the first transfer carrier 1 loads the workpiece in the workpiece buffer area 100 to install the required separate fork frame, and transfers it to the lane placement area 200. The empty first transfer carrier 1 left after the complete set of pallet area 300 sorts the pallets is returned to the workpiece buffer area 100 to install and transport the new separate fork frame to be matched, and the logistics cycle is carried out; the sub-packaging line material distribution area 500 corresponds to the outbound position arrangement of the complete set buffer area 400, and a material distribution line 11 is provided in the sub-packaging line material distribution area 500. The complete set of fork arms is transported from the complete set buffer area 400 to the sub-packaging line material distribution area 500 through the second transfer carrier 2, and the material is provided through the material distribution line 11 for the assembly of the scissors fork arms. After the assembly is completed, the empty second transfer carrier 2 returns to the complete set of pallet area 300 to carry out the logistics cycle.

[0039] As a specific embodiment of the conveying and caching system of the present invention, the transfer carrier can be a skid, which is used in conjunction with a roller bed for transfer and transportation. The roller bed completes the rapid transportation and accumulation of the skid between the previous and next processes, realizing controllable transportation of the skid, easily realizing material transfer between the fast line and the slow line, and enabling smooth transfer of workpieces between the two logistics circulation systems of the present invention, thereby reducing transfer waste. In addition, a crawler belt can be used instead of a roller bed, and the skid can be transported by crawler belt transportation. The transfer carrier can also be a slide plate, which can be used in conjunction with a roller bed or crawler belt to achieve the transfer of workpieces.

[0040] It should be noted that the skid is generally used for horizontal straight line transportation, see Figure 1, the first transfer carrier 1 and the second transfer carrier 2 can perform horizontal linear transportation in the X direction. In order to realize the transportation in the Y direction of the first transfer carrier 1, it is convenient for the first transfer carrier 1 to transport back and forth between the workpiece buffer area 100, the lane placement area 200 and the complete set of tray area 300. A first moving machine 3 is provided between the workpiece buffer area 100 and the lane placement area 200, and a second moving machine 4 is provided between the complete set of tray area 300 and the workpiece buffer area 100. The first moving machine 3 and the second moving machine 4 are both arranged along the Y direction. Through the first moving machine 3, the workpiece The first transfer carrier 1 transferred from the workpiece buffer area 100 is transferred and transported in the Y direction, and according to the arrangement rules, the first transfer machine 3 can move the first transfer carrier 1 along the Y direction to the position of the partition lane corresponding to the first transfer carrier 1, so that the first transfer carrier 1 can be unloaded from the first transfer machine 3 and can be directly transported to its corresponding partition lane along the X direction for storage; and through the second transfer machine 4, the empty first transfer carrier 1 left after the sorting of the complete set of pallets 300 is completed can be transferred and transported in the Y direction, thereby returning to the workpiece buffer area 100.

[0041] As a preferred embodiment of the cache delivery system of the present invention, see Figure 1 The moving track of the first moving machine 3 and the moving track of the second moving machine 4 both extend to the material distribution area 500 of the sub-packaging line. The second transfer carrier 2 located in the material distribution area 500 of the sub-packaging line can be transported in the Y direction through the first moving machine 3 or the second moving machine 4, so that the empty second transfer carrier 2 is transported back to the complete set of pallet area 300, and the complete set of fork arms with pallets are installed and transported. The first moving machine 3 and the second moving machine 4 are shared, and there is no need to set up additional moving machines, which improves the utilization rate of the equipment and facilitates layout.

[0042] As a specific embodiment of the buffer conveying system of the present invention, the complete set of tray area 300 is provided with a manipulator moving track for the movement of the sorting tray manipulator 5. The partition lanes in the lane placement area 200 are arranged in a row, and the manipulator moving track is arranged corresponding to the partition lanes to facilitate the first transfer carrier 1 in each partition lane to be able to move to the manipulator moving track according to the placement order of the partition lane where it is stored. Figure 1 The partition lanes in the partition placement area 200 are arranged in a row along the Y direction, which makes it easy for the first moving machine 3 to move the first transfer carrier 1 transferred from the workpiece buffer area 100 to its corresponding partition lane. At the same time, the manipulator moving track is also arranged along the Y direction. The first transfer carrier 1 in the partition lane in the partition placement area 200 can be moved in the X direction to the manipulator moving track without changing the set order, so that the sorting and distribution robot 5 can accurately grab the individual forks in order for distribution.

[0043] To improve the efficiency of the plate distribution, see Figure 1The second transfer carrier 2 located in the complete set of pallet distribution area 300 is arranged in the middle of the manipulator moving track, and on the manipulator moving track, sorting and distribution manipulators 5 are respectively provided on both sides of the second transfer carrier 2, that is, the sorting and distribution manipulator 5 on the upper side of the second transfer carrier 2 is used to sort the separate fork racks of the pallets to be distributed on the upper side of the second transfer carrier 2, and the sorting and distribution manipulator 5 on the lower side of the second transfer carrier 2 is used to sort the separate fork racks of the pallets to be distributed on the lower side of the second transfer carrier 2. Production instructions are issued through MES (production information management system), so that the sorting and distribution manipulators 5 on both sides can grab the workpieces in sequence according to the product configuration to realize collaborative operation, and can sort the separate forks in sequence by moving up and down in the shortest distance, and move to the second transfer carrier 2 in the middle for efficient distribution.

[0044] In order to facilitate the Y direction movement of the complete set buffer area 400 when entering and leaving the warehouse, see Figure 1 The entry and exit positions of the complete set buffer area 400 are respectively provided with an entry transfer machine 6 and an exit transfer machine 7. The entry transfer machine 6 and the exit transfer machine 7 are respectively located on the left and right sides of the complete set buffer area 400. The second transfer carrier 2 of the complete set pallet area 300 moves the complete set of fork arms with the pallet completed along the X direction to the entry transfer machine 6, and realizes the Y direction movement through the entry transfer machine 6 to move the complete sets of fork arms of different models to the corresponding storage areas. When it is necessary to exit the warehouse, the second transfer carrier 2 moves the stored complete set of fork arms along the X direction to the exit transfer machine 7, and realizes the Y direction movement through the exit transfer machine 7 to transfer the complete set of fork arms to the sub-assembly line material distribution area 500 for component assembly.

[0045] As a preferred embodiment of the cache delivery system of the present invention, see Figure 1 and Figure 2 The storage warehouse of the complete set of buffer area 400 is a three-dimensional warehouse 8, and a plurality of inbound transfer machines 6 and a plurality of outbound transfer machines 7 are provided corresponding to the number of layers of the three-dimensional warehouse 8. The plurality of inbound transfer machines 6 are equipped with an inbound elevator 9 capable of transferring the second transfer vehicle 2 in the height direction, and the plurality of outbound transfer machines 7 are equipped with an outbound elevator 10 capable of transferring the second transfer vehicle 2 in the height direction, realizing multi-layer and multi-channel three-dimensional storage and automatic access, greatly reducing storage and transportation costs, alleviating labor intensity, and improving warehouse space utilization.

[0046] In order to improve the intelligence rate, preferably, the transfer carrier is provided with a code carrier. When the first transfer carrier 1 installs a separate fork frame on the workpiece buffer area 100, it uses its own code carrier to give an identification code to each separate fork frame. When the first transfer carrier 1 transfers the separate fork frame, the code carrier reading and writing device automatically reads the data stored in the code carrier installed on the first transfer carrier 1, and performs automatic transfer and delivery as well as pallet matching. For example, a code carrier reading and writing device is provided on the first moving machine 3 to accurately transfer the first transfer carrier 1 to the corresponding partition lane; after the complete pallet matching area 300 completes the pallet matching, the second transfer carrier 2 in the complete pallet matching area 300 uses its own code carrier to bind with the complete fork arm, thereby cooperating with the code carrier reading and writing device to realize fully automated transfer, facilitate warehousing and outbound transportation, greatly reduce manual work, and improve production efficiency.

[0056] S9: After the assembly is completed, the empty second transfer vehicle 2 is transferred from the sub-assembly line material distribution area 500 to the complete set of pallets area 300 through the first transfer machine 3 or the second transfer machine 4.

[0057] The cache conveying system of the present invention replaces manual fork installation and rotation, reduces the number of operators, can automatically match trays, and reduces the labor intensity of operators. Through information technology, it binds the information of a single fork frame or a set of fork arms, and realizes automatic conveying flow, automatic shift sorting and automatic layer storage according to the set program, realizes first-in-first-out, reduces sluggishness, and responds to precise iteration of engineering changes in a timely manner. It also adopts seamless docking of the dual logistics circulation system, realizes the logistics cycle from a single fork frame to the matching tray through the transfer cycle of the first transfer carrier 1, and can connect the workpiece cache area 100 to the paint shop production to meet the fast-paced production needs. The transfer cycle of the second transfer carrier 2 realizes the cache conveying cycle of the complete matching tray to meet the production needs of high-efficiency assembly workshops. The logistics is fast and orderly, which reduces transfer waste and improves productivity. At the same time, the cache conveying system of the present invention is provided with a workpiece cache area 100 and a complete set cache area 400, which can cache the individual fork arms that have been painted and the complete set of fork arms that need to be assembled.
