Description

Technical Field

[0001] The invention belongs to the technical field of wire drawing machines, and in particular relates to an automatic storage and feeding method for a tooling tray of a wire drawing machine. Background Art

[0002] At present, in the production process of cables such as land cables and submarine cables, a copper wire drawing process is usually required. The raw material of the copper wire drawing process is the copper wire wound on the copper wire reel. The copper wire with a thicker diameter is processed into the required copper wire with a thinner diameter through the wire drawing process. The copper wire processed by the wire drawing machine needs to be wound on an empty tooling reel. The storage of a large number of empty tooling reels requires a large space in the workshop; at the same time, a large number of full tooling reels with copper wire wound on them also require a large space in the workshop. There is no good storage and loading solution for empty tooling reels and full tooling reels in the existing technology.

[0003] Since full pallets are heavy, empty pallets are also heavy, and it is difficult to use a forklift to store them; loading and unloading empty pallets and unloading full pallets into the warehouse require manual operation, which takes up manpower and handling equipment, seriously affecting production efficiency. Summary of the invention

[0004] In view of the above technical problems, the present invention provides a wire drawing machine tool tray automatic storage and feeding system and method. The technical solution adopted by the present invention is as follows:

[0005] The automatic storage and loading system of the tooling trays of the wire drawing machine comprises a transfer AGV trolley, a wire drawing machine and two rows of parallel tooling tray storage racks located on one side of the wire drawing machine, the tooling tray storage rack far away from the wire drawing machine is a continuous grid-like three-dimensional structure, the tooling tray storage rack close to the wire drawing machine is a segmented grid-like three-dimensional structure, and an outbound conveyor line, an inbound conveyor line and a wire drawing machine loading conveyor line are respectively arranged between adjacent segmented grid-like three-dimensional structures, and a stacker is movably installed between the two rows of tooling tray storage racks; two parallel overhead rails are installed on the other side of the wire drawing machine, and the length direction of the overhead rails is consistent with the length direction of the tooling tray storage racks, a rewinding machine is arranged on the inner side of one end of the two overhead rails, a semi-finished product tray placement rack is arranged on the outer side of the rewinding machine, a full tray placement rack is arranged on the rewinding machine, and a copper wire support rack is arranged between the full tray placement rack and the semi-finished product tray placement rack; the outbound conveyor line, the inbound conveyor line and the wire drawing machine loading conveyor line extend from one end of the tooling tray storage rack to between the two overhead rails, and a truss robot is slidably installed on the overhead rails.

[0006] Preferably, an empty tooling tray buffer area and a full tooling tray buffer area are respectively provided between the two overhead rails.

[0007] Preferably, the stacker is movably installed between two rows of tooling tray storage racks via overhead rails and floor rails.

[0008] Preferably, the truss robot is equipped with a visual recognition sensor, and the wire drawing machine and the full tooling disc buffer and the empty tooling disc buffer are provided with position sensors.

[0009] The automatic storage and loading method of the tooling tray of the wire drawing machine, using the automatic storage and loading system of the tooling tray of the wire drawing machine, comprises the following steps:

[0010] Automatic warehousing of empty tool trays: When the wire drawing machine needs to load empty tool trays, the stacker forks the empty tool tray from the corresponding position of the tool tray storage rack and places it on the wire drawing machine feeding conveyor line to automatically load the empty tool tray out of the warehouse; the semi-finished trays generated by other processes are transferred to the rewinding machine by the transfer AGV trolley, and two semi-finished trays are manually fixed on the semi-finished tray placement rack and the full tray placement rack. After the rewinding machine completes multiple rounds of rewinding, the semi-finished trays on the semi-finished tray placement rack become empty tool trays. The empty tool trays generated by the rewinding machine and the empty tool trays generated by other processes are transferred to the empty tool tray buffer by the transfer AGV trolley. The truss robot grabs the empty tool trays in the empty tool tray buffer and places them on the storage conveyor line. The storage conveyor line transports the empty tool trays to the tool tray storage rack. The stacker forks the empty tool tray and places it at the corresponding position of the tool tray storage rack to automatically store the empty tool trays.

[0011] Full trays are automatically put in and out of storage: Full trays are sent out from the unloading conveyor line of the wire drawing machine. The truss robot covering the unloading conveyor line of the wire drawing machine grabs the full tray and places it in the full tray buffer. After the semi-finished tray is wound into a full tray by the rewinding machine, the full tray is manually pushed to the edge of the rewinding machine, and then transported to the full tray buffer by the transfer AGV trolley. The truss robot grabs the full tray from the full tray buffer and places it on the storage conveyor line. The storage conveyor line transports the full tray to the tray storage rack , the stacker fork picks up the full tooling tray and places it at the corresponding position of the tooling tray storage rack, and the full tooling tray is automatically put into storage; when the downstream process requires a full tooling tray and there is no full tooling tray in the full tooling tray buffer, the stacker grabs the full tooling tray at the corresponding position of the tooling tray storage rack and places it on the outbound conveyor line. The outbound conveyor line transports the full tooling tray to the area covered by the truss robot. The truss robot grabs the full tooling tray and places it in the full tooling tray buffer. The transfer AGV then transports it to the required position in the workshop for automatic outbound delivery of the full tooling tray.

[0012] Preferably, the visual recognition sensor on the truss robot assists the truss robot in identifying the position of the tooling tray and then grabbing the tooling tray, and the position sensor uploads the position information of the full tooling tray or the empty tooling tray to the automatic storage and feeding system.

[0013] Beneficial effects of the present invention:

[0014] 1. The present invention uses a three-dimensional storage structure to improve the space utilization rate of the wire drawing machine production line, reduce the large amount of workshop area occupied by tooling trays, and save material storage space; 2. Combined with the use of truss robots, transfer AGV carts, stackers and other equipment, the automatic warehousing and storage and outbound loading of tooling trays are realized, which improves the degree of automation and reduces labor costs and occupation of handling equipment; 3. A tooling tray conveyor line is set at the outbound position, and no manual operation is required in the middle, saving labor costs; at the same time, the automatic recovery of empty tooling trays is realized.

DETAILED DESCRIPTION

[0022] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Embodiment 1

[0023] like Figure 1-4As shown, two wire drawing machines 4 are arranged side by side at the wire drawing process site, and the wire drawing machine tool tray automatic storage and loading system is installed at the wire drawing process tool tray storage, loading and transportation work site used in cable production, including a tool tray three-dimensional storage warehouse 1, the tool tray three-dimensional storage warehouse 1 includes two rows of parallel tool tray storage racks 9 arranged on one side of the two wire drawing machines 4, the tool tray storage rack 9 is a grid-like three-dimensional structure, and the stacker 13 is movably installed between the two rows of tool tray storage racks 9 through the ceiling rail and the ground rail. The tool tray storage rack 9 far away from the wire drawing machine 4 is a continuous integrated structure, which can store more tool trays 10, and the tool tray storage rack 9 close to the wire drawing machine 4 is a segmented structure. The space between adjacent segmented structures is provided with a warehouse-out conveyor line 2, a warehouse-in conveyor line 12 and a wire drawing machine loading conveyor line 11, and each wire drawing machine 4 is provided with a wire drawing machine loading conveyor line 11 on the left and right sides.

[0024] Two parallel overhead rails are installed on the other side of the two wire drawing machines 4. The length direction of the overhead rails is parallel to the length direction of the tooling disk storage rack 9. The positions between the two overhead rails corresponding to the two wire drawing machines 4 are respectively set as an empty tooling disk buffer 5 and a full tooling disk buffer 7. A rewinding machine 8 is arranged on the inner side of one end of the two overhead rails. The rewinding machine 8 is located between the two overhead rails. A semi-finished disk placement rack 15 is arranged on the right side of the rewinding machine 8. A generated full disk placement rack 14 is arranged on the rewinding machine 8. A copper wire support rack is arranged between the generated full disk placement rack 14 and the semi-finished disk placement rack 15. The full disk placement rack 14 is close to the full tooling disk buffer 7, and the semi-finished disk placement rack 15 is located outside the ends of the two overhead rails. The outgoing conveyor line 2, the incoming conveyor line 12 and the wire drawing machine loading conveyor line 11 extend from one end of the tooling tray storage rack 9 to the lower space between the two overhead rails. The truss robot 3 is slidably installed on the overhead rails. The automatic ingoing and outgoing of the tooling tray 10 and the automatic loading of the wire drawing machine are realized through the truss robot 3, the outgoing conveyor line 2, the incoming conveyor line 12 and the wire drawing machine loading conveyor line 11.

[0025] The transfer AGV trolley 6 is used to transfer empty tool trays generated by other processes, and to transport full tool trays to other processes.

[0026] The stacker 13 is an existing product. The stacker 13 is mainly composed of a lower crossbeam, an upper crossbeam, a column, a cargo platform, a lifting mechanism and corresponding accessories. The lower crossbeam mainly supports the entire stacker 13, and the motor drives the walking wheel to provide power for the stacker 13. There is a set of guide wheels at each end of the lower crossbeam, which mainly plays a guiding role and enables the stacker 13 to move along the ground rail. The upper crossbeam mainly connects the two columns and fixes the pulley. At the same time, there is a set of guide wheels at each end of the upper crossbeam, which enables the stacker 13 to move along the direction of the ceiling rail. The cargo platform mainly plays the role of fixing the fork and supporting the goods, and the lifting mechanism mainly provides lifting power for the cargo platform. As a key equipment of the stereoscopic warehouse, the stacker 13 runs at high speed in a high and narrow lane, and the equipment reliability and operation stability are particularly important. In order to ensure the safety of personnel, goods and equipment, the stacker 13 is equipped with complete mechanical hardware, electrical hardware protection functions, and safety protection functions in terms of control procedures.

[0027] The truss robot 3 is provided with a visual recognition sensor. The wire drawing machine 4 and the full tooling plate buffer 7 and the empty tooling plate buffer 5 are provided with position sensors.

[0028] After loading an empty tool tray, the truss robot 3 scans along a given running track and identifies the position, shape and other parameters of the workpiece, and determines the sling required to transport the workpiece through the control system, completes the transportation of the workpiece, and stores it in the designated position. The truss robot 3 is a prior art, mainly composed of manipulator tracks, frames, trolley transmission mechanisms, lifting columns, sling rotation mechanisms, sling quick-change mechanisms, and steel plate slings. In order to improve production efficiency, two truss robots 3 are set on the overhead track, and the layout form of regional and segmented control is adopted, so that each truss robot 3 is responsible for the loading work of a wire drawing machine 4 alone. Embodiment 2

[0029] like Figure 5 As shown, the method for automatically storing and loading the tooling tray of a wire drawing machine using the automatic storage and loading system of the tooling tray of the wire drawing machine described in the first embodiment includes the following steps:

[0030] The outbound range of the tooling tray stereoscopic storage warehouse 1 overlaps with the end positions of the wire drawing machine loading conveyor lines 11 on both sides of the wire drawing machine 4. When the wire drawing machine 4 needs to load empty tooling trays, the stacker 13 can directly fork the empty tooling tray from the corresponding position of the tooling tray storage rack 9 and place it on the wire drawing machine loading conveyor line 11. The empty tooling tray is automatically transported to the copper wire winding station of the wire drawing machine 4 through the wire drawing machine loading conveyor line 11, thereby realizing the automatic outbound delivery of the empty tooling tray.

[0031] After the full work tray is used in other processes, empty work trays or semi-finished product trays may be generated; the semi-finished product trays need to be transported to the vicinity of the rewinding machine 8 by the transfer AGV trolley 6 for rewinding, and the two semi-finished product trays are manually fixed on the semi-finished product tray placement rack 15 and the full tray placement rack 14 respectively. The copper wire tail of the semi-finished product tray on the semi-finished product tray placement rack 15 is supported by the copper wire support rack and manually connected to the copper wire tail of the semi-finished product tray on the full tray placement rack 14. After the rewinding machine 8 performs multiple rounds of rewinding, the copper wire of the semi-finished product tray on the semi-finished product tray placement rack 15 is wound onto the semi-finished product tray on the full tray placement rack 14. After the rewinding is completed, the semi-finished product tray on the semi-finished product tray placement rack 15 becomes an empty work tray. The empty tool trays generated by the rewinding machine 8 and the empty tool trays generated by other processes are transferred to the empty tool tray buffer area 5 by the transfer AGV cart 6. The truss robot 3 moves on the overhead track to grab the empty tool trays in the empty tool tray buffer area 5 and place them on the warehousing conveyor line 12. The warehousing conveyor line 12 conveys the empty tool trays to the tool tray storage rack 9 (stacker 13). The stacker 13 forks the empty tool trays and places them at the corresponding position of the tool tray storage rack 9 according to the instructions of the automatic storage and loading system, so as to automatically put the empty tool trays into storage.

[0032] The tooling disks 10 produced by the wire drawing machine 4 are all full tooling disks. After the winding is completed, the full tooling disks are sent out from the unloading conveyor line of the wire drawing machine 4. The wire drawing machine 4 will upload the position information of the wound full tooling disks to the system through the position sensor. The truss robot 3 covering the unloading conveyor line of the wire drawing machine 4 will grab the full tooling disks according to the position information and place them in the full tooling disk buffer area 7. The position sensor in the full tooling disk buffer area will upload the position information of each full tooling disk to the system, which is convenient for the truss robot 3 to grab.

[0033] After the semi-finished disk is wound into a full disk by the rewinding machine 8, the full disk on the full disk placement rack 14 is manually pushed to the edge of the rewinding machine 8, and then transferred to the full disk buffer 7 by the transfer AGV trolley 6. The truss robot 3 grabs the full disk from the full disk buffer 7, moves and places the full disk on the storage conveyor line 12, and then the full disk is automatically stored by the stacker 13.

[0034] When the downstream process requires a full work pallet and there is no full work pallet in the full work pallet buffer 7, the stacker 13 grabs the full work pallet at the corresponding position of the work pallet storage rack 9 and places it on the outbound conveyor line 2 according to the instructions of the automatic storage and loading system; the outbound conveyor line 2 transports the full work pallet to the area covered by the truss robot 3, the truss robot 3 grabs the full work pallet and places it in the full work pallet buffer 7, and then the transfer AGV cart 6 transports it to the required position in the workshop.

[0035] The visual recognition sensor on the truss robot 3 assists the truss robot 3 in identifying the position of the tooling tray and then grabbing the tooling tray. The position sensor uploads the position of a full tooling tray or an empty tooling tray to the automatic storage and loading system.

[0036] Empty tool trays and semi-finished product trays are produced from tool trays transported to other workshops, and are transported to the rewinding machine 8 by the transfer AGV trolley 6. After manual identification, the empty tool tray is transported to the empty tool tray buffer 5 by the manually controlled transfer AGV trolley 6, and the semi-finished product tray is manually installed on the rewinding machine 8 for rewinding. The empty tool trays and full tool trays produced by rewinding are transported to the full tool tray buffer 7 or the empty tool tray buffer 5 by the manually controlled transfer AGV trolley 6, and the tool tray 10 uploads its position information to the system through the position sensors at the two buffers for the truss robot 3 to grab.

[0037] In the embodiments of the present invention, technical features that are not described in detail are all existing technologies or conventional technical means and will not be described in detail here.

[0038] Finally, it should be noted that the above embodiments are only specific implementation methods of the present invention, which are used to illustrate the technical solutions of the present invention, rather than to limit them, and the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that any technician familiar with the technical field can modify the technical solutions recorded in the above embodiments within the technical scope disclosed by the present invention, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention, and should be covered within the protection scope of the present invention.
