[0001] This invention relates to the field of AGV mold changing, and particularly to an AGV mold changing system and method for edge banding machines. Background Technology

[0002] In the production process of the edge banding machine industry, the edge banding mold needs to be changed according to the product specifications. Currently, when changing the mold, it is necessary to first retrieve the mold to be replaced from the mold library, then move it to one side of the edge banding machine, then take out the old mold and push in the new mold. This process takes a lot of time.

[0003] For example, Chinese patent CN202010399883.3 discloses a dual-station fully automatic mold-changing trolley for changing molds in large equipment, used for fully automatic and rapid mold changing on the production site. The first station component and the second station component are respectively installed on the left and right sides of the trolley structure transmission component, which is rolledly connected to the rails, which are laid in front of the equipment. Under the electrical control of the electrical control system, the trolley structure transmission component can move freely along the left and right directions of the rails. The electrical control system controls the mold to be replaced to be automatically pulled out from the equipment and installed on the first station component, and automatically pushes the mold to be installed on the second station component into the equipment, completing the fully automatic mold replacement. However, the above replacement method has a long mold replacement time and low mold replacement efficiency. Summary of the Invention

[0004] The technical problem solved by this invention is to provide a mold changing system for an edge banding machine AGV, which can improve mold changing efficiency and greatly shorten mold changing time.

[0005] The technical solution adopted by the present invention to solve its technical problem is: an AGV mold changing system for an edge banding machine, including an edge banding machine, wherein a first inlet / outlet mold changing platform and a second inlet / outlet mold changing platform are respectively provided at the inlet and outlet of the edge banding machine, a first storage edge storage bin and a second storage edge storage bin are respectively provided on both sides of the first inlet / outlet mold changing platform, a third storage edge storage bin and a fourth storage edge storage bin are respectively provided on both sides of the second inlet / outlet mold changing platform, the first inlet / outlet mold changing platform, the first storage edge storage bin, the second storage edge storage bin, the third storage edge storage bin and the fourth storage edge storage bin are all provided with AGV guide rails, and the system also includes an AGV mold changing trolley that moves along the AGV guide rails;

[0006] When a mold changing operation is required, the AGV mold changing trolley moves along the AGV guide rail to the corresponding storage side. The AGV mold changing trolley pulls the mold on the storage side to the adjacent infeed / outfeed mold changing platform. The two infeed / outfeed mold changing platforms start simultaneously. One infeed / outfeed mold changing platform pulls the old mold out of the hemming machine, and the other infeed / outfeed mold changing platform sends the new mold into the hemming machine. The AGV mold changing trolley moves along the AGV guide rail to the infeed / outfeed mold changing platform corresponding to the old mold, pulls the old mold onto the AGV mold changing trolley, and moves along the AGV guide rail to an empty storage side, storing the mold in the storage side.

[0007] Furthermore, both the first and second infeed / outfeed mold changing platforms include a first machine base. The first machine base is equipped with a double-hook chain push-pull assembly and a lifting drive mechanism that drives the double-hook chain push-pull assembly to move up and down. The double-hook chain push-pull assembly includes a component frame. The component frame is provided with first guide rails on both sides.

[0008] Furthermore, the first machine platform is provided with multiple rows of first support rollers, and the first machine platform is provided with first guards on both sides, and multiple first guide rollers are provided on the inner side of the first guards.

[0009] Furthermore, the AGV mold changing trolley includes a second machine platform, on which multiple rows of second support rollers are provided. An AGV push-pull device is provided on one side of the second machine platform. The AGV push-pull device includes an AGV push-pull guide rail and an AGV push-pull hook disposed in the AGV push-pull guide rail. It also includes an AGV push-pull drive mechanism that drives the AGV push-pull hook to move along the AGV push-pull guide rail.

[0010] The first machine platform is also equipped with a front lifting stop pin and a rear lifting stop pin, and the first machine platform is also equipped with a third guide rail that cooperates with the AGV push-pull guide rail.

[0011] The second machine base is provided with second guards on both sides, and multiple second guide rollers are provided on the inner side of the second guards.

[0012] Furthermore, the AGV push-pull guide rail is also provided with a flip-pull track at its front end, and the second support roller track is provided with a flip-support roller track at its front end. A transmission connecting frame is provided between the flip-support roller track and the flip-pull track. One end of the flip-support roller track near the second support roller track is connected to a lifting assembly. The lifting assembly is set on a second machine platform. The roller body of the flip-support roller track is connected to a rotating shaft assembly set on the second machine platform. The lifting assembly is configured to drive the flip-support roller track to rotate around the rotating shaft assembly. The flip-support roller track rotates synchronously with the flip-pull track.

[0013] Furthermore, the second machine is equipped with a traveling wheel and an AGV navigation module at its bottom. The bottom of the second machine is also equipped with a positioning column and a positioning column drive mechanism that drives the positioning column to move up and down. A positioning block that cooperates with the positioning column is provided on the ground, and a positioning through hole for the positioning column to be inserted is provided in the middle of the positioning block.

[0014] Furthermore, the first, second, third, and fourth storage side warehouses all include a third machine platform.

[0015] This invention also discloses a mold changing method for an AGV (Automated Guided Vehicle) for an edge banding machine. The steps are as follows: When a mold changing operation is required, the AGV mold changing trolley moves along the AGV guide rail to the corresponding storage side of the edge banding machine. The AGV mold changing trolley pulls the mold on the storage side of the edge banding machine to the adjacent inlet / outlet mold changing platform. The two inlet / outlet mold changing platforms start simultaneously. One inlet / outlet mold changing platform pulls out the old mold from the edge banding machine, and the other inlet / outlet mold changing platform sends the new mold into the edge banding machine. The AGV mold changing trolley moves along the AGV guide rail to the inlet / outlet mold changing platform corresponding to the old mold and pulls the old mold onto the AGV mold changing trolley. The AGV mold changing trolley moves along the AGV guide rail to an empty storage side banding machine and stores the mold in the storage side banding machine.

[0016] The beneficial effects of this invention are: the system can realize the simultaneous entry and exit of molds through two mold changing tables, which shortens the actual single mold exchange time to 30s. At the same time, the use of multiple storage side warehouses can reduce the retrieval time of the side warehouses. In addition, when the number of mold warehouses increases, the AGV mold changing trolley can also be used as a turnover vehicle. Attached Figure Description

[0025] Specific implementation party

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] like Figure 1As shown, embodiments of this application disclose an AGV mold changing system for an edge banding machine, including an edge banding machine 1. A first inlet / outlet mold changing platform 2 and a second inlet / outlet mold changing platform 3 are respectively provided at the inlet and outlet of the edge banding machine 1. A first storage edge storage 4 and a second storage edge storage 5 are respectively provided on both sides of the first inlet / outlet mold changing platform 2. A third storage edge storage 6 and a fourth storage edge storage 7 are provided on both sides of the second inlet / outlet mold changing platform 3. An AGV guide rail 9 is provided between the second inlet / outlet mold changing platform 3, the first inlet / outlet mold changing platform 2, the first storage edge storage 4, the second storage edge storage 5, the third storage edge storage 6 and the fourth storage edge storage 7. The system also includes an AGV mold changing trolley 8 that moves along the AGV guide rail 9.

[0028] When a mold changing operation is required, the AGV mold changing trolley moves along the AGV guide rail 9 to the corresponding storage side. The AGV mold changing trolley pulls the mold on the storage side to the adjacent infeed mold changing platform. The two infeed mold changing platforms start simultaneously. One infeed mold changing platform pulls out the old mold from the edge banding machine 1, and the other infeed mold changing platform sends the new mold into the edge banding machine 1. The AGV mold changing trolley 8 moves along the AGV guide rail 9 to the infeed mold changing platform corresponding to the old mold, pulls the old mold onto the AGV mold changing trolley, and moves along the AGV guide rail 9 to an empty storage side, storing the mold in the storage side.

[0029] When using this AGV mold changing system, the mold to be updated is first placed on one of the infeed / outfeed mold changing tables by the AGV mold changing trolley. Then, the mold is simultaneously fed and unfurled through two infeed / outfeed mold changing tables, which can reduce the mold changing time by at least half. According to actual operation, the actual single mold exchange time is reduced to 30 seconds. At the same time, the setting of multiple storage side warehouses can reduce the retrieval time of the side warehouses. In addition, when the number of mold warehouses increases, the AGV mold changing trolley 8 can also be used as a turnover vehicle, which greatly improves the mold changing efficiency and significantly shortens the mold changing time.

[0030] In this embodiment, as Figure 2 As shown, both the first infeed / outfeed mold changing platform 2 and the second infeed / outfeed mold changing platform 3 include a first machine base 201. The first machine base 201 is equipped with a double hook chain push-pull assembly and a lifting drive mechanism for driving the double hook chain push-pull assembly to move up and down. The double hook chain push-pull assembly includes an assembly frame. The assembly frame is provided with first guide rails 202 on both sides. The first guide rail 202 is provided with a first push-pull hook 203 and a chain push-pull drive mechanism 204 for driving the first push-pull hook to move within the first guide rail. The first machine base 201 is provided with a second guide rail 205 corresponding to the first guide rail 202. When the assembly frame rises, the first guide rail 202 and the second guide rail 205 are connected.

[0031] In specific operation, if the first infeed / outfeed mold changing platform 2 needs to receive the subsequent new mold material, the double hook chain push-pull assembly is in a descending state. At this time, the AGV mold changing trolley 8 can push the new mold into the infeed / outfeed mold changing platform. Then, the first infeed / outfeed mold changing platform 2 and the second infeed / outfeed mold changing platform 3 work simultaneously. The double hook chain push-pull assembly on the first infeed / outfeed mold changing platform 2 rises, and the chain push-pull drive mechanism 204 drives the first push-pull hook 203 to hook the edge of the mold. Under the action of the chain push-pull drive mechanism 204, the first push-pull hook 203 moves along the first guide rail 202 and the second guide rail 205, pushing the new mold into the edge banding machine 1. The chain push-pull drive mechanism 204 on the second infeed / outfeed mold changing platform 3 drives the first push-pull hook 203 to move towards the old mold and hook the edge of the old mold to pull the old mold out of the edge banding machine 1.

[0032] Specifically, the chain push-pull drive mechanism 204 mentioned above is an existing structure, and its specific structure will not be described in detail here.

[0033] In the aforementioned mechanism, the lifting double hook chain push-pull assembly allows the mold to pass through the top of the push-pull hook, thus enabling bidirectional loading and unloading. At the same time, a major advantage of the chain is that it converts the rotary motion of the motor into the linear motion of the push-pull device through the sprocket, resulting in more stable and precise force application when pushing and pulling the mold. Furthermore, the chain retracts into the chain storage box when it retracts, saving space and facilitating maintenance.

[0034] In this embodiment, the first machine base 201 is provided with multiple rows of first support rollers, and the first machine base 201 is provided with first guards 207 on both sides, and multiple first guide rollers 208 are provided on the inner side of the first guards 207.

[0035] When the mold is pushed in and pulled out, it can move through the first support roller, while both sides are guided by the first guide rollers 208.

[0036] The aforementioned first support roller and first guide roller 208 configuration can, on the one hand, reduce driving force, making the mold run more smoothly, and on the other hand, ensure that the mold does not deviate during operation.

[0037] In this embodiment, as Figure 3 and Figure 4 As shown, the AGV mold changing trolley 8 includes a second machine base 801, on which multiple rows of second support roller conveyors 811 are provided. An AGV push-pull device 802 is provided on one side of the second machine base 801. The AGV push-pull device 802 includes an AGV push-pull guide rail 803 and an AGV push-pull hook disposed in the AGV push-pull guide rail 803. It also includes an AGV push-pull drive mechanism that drives the AGV push-pull hook to move along the AGV push-pull guide rail 803.

[0038] The first machine base 201 is also provided with a front lifting stop pin 209 and a rear lifting stop pin 210, and the first machine base 201 is also provided with a third guide rail 206 that cooperates with the AGV push-pull guide rail 803.

[0039] The second machine base 801 is provided with second guards 804 on both sides, and multiple second guide rollers are provided on the inner side of the second guards 804.

[0040] In specific operation, when the AGV mold changing trolley 8 needs to place the mold into the first inlet / outlet mold changing platform 2 and the second inlet / outlet mold changing platform 3, the third guide rail 206 is connected to the AGV push-pull guide rail 803. The front lifting stop pin 209 on the first machine base 201 rises, the AGV push-pull hook hooks onto the edge of the mold, and the AGV push-pull drive mechanism drives the AGV push-pull hook to move, pushing the mold onto the first inlet / outlet mold changing platform 2 and the second inlet / outlet mold changing platform 3. The rear lifting stop pin 210 rises, and the AGV push-pull hook retracts. When the AGV mold changing trolley 8... When the AGV needs to pull the mold out from the first inlet / outlet mold changing table 2 or the second inlet / outlet mold changing table 3, the third guide rail 206 is connected to the AGV push-pull guide rail 803. The rear lifting stop pin 210 on the first machine 201 descends, and the AGV push-pull drive mechanism drives the AGV push-pull hook to move. The AGV push-pull hook catches the edge of the mold and pulls the mold out from the first inlet / outlet mold changing table 2 or the second inlet / outlet mold changing table 3 to the AGV mold changing trolley 8, realizing the transfer function. The AGV mold changing trolley 8 sends the mold to the storage side warehouse in the same principle.

[0041] The aforementioned AGV mold changing trolley 8 enables mold transfer, that is, the pulling out and feeding of molds, ensuring the automation of the entire mold changing operation.

[0042] In this embodiment, as Figure 6 and Figure 7 As shown, the AGV push-pull guide rail 803 is further provided with a flip-pull track 807 at its front end, and the second support roller track 811 is provided with a flip-support roller track 808 at its front end. A transmission connecting frame 809 is provided between the flip-support roller track 808 and the flip-pull track 807. The end of the flip-support roller track 808 near the second support roller track 811 is connected to a lifting assembly. The lifting assembly is provided on the second machine base 801. The roller body of the flip-support roller track 808 is connected to a rotating shaft assembly 810 provided on the second machine base 801. The lifting assembly is configured to drive the flip-support roller track 808 to rotate around the rotating shaft assembly 810. The flip-support roller track 808 rotates synchronously with the flip-pull track 807.

[0043] The lifting assembly may be an electric cylinder assembly 812.

[0044] Specifically, when the AGV mold-changing trolley cannot seamlessly connect with the inlet / outlet mold-changing platform or storage side warehouse, an extended tilting support roller conveyor 808 and a tilting push-pull track 807 need to be installed to connect with the inlet / outlet mold-changing platform or storage side warehouse. During the AGV mold-changing trolley's movement, to avoid other obstacles, such as pillars near the inlet / outlet mold-changing platform or storage side warehouse, the tilting support roller conveyor 808 can be driven to rotate via a lifting assembly. For example, the tilting support roller conveyor 808 can rotate from a horizontal state to a vertical state. Since a transmission connecting frame 809 is provided between the tilting push-pull track 807 and the tilting support roller conveyor 808, the tilting push-pull track 807 will rotate synchronously with the tilting support roller conveyor 808, meaning the tilting push-pull track 807 will also rotate to a vertical state. In this way, during the AGV mold-changing trolley's movement, the tilting support roller conveyor 808 and the tilting push-pull track 807 will not collide with obstacles.

[0045] Once the AGV mold-changing trolley has moved to the target position, both the tilting support roller conveyor 808 and the tilting push-pull track 807 can be rotated to a horizontal position, allowing them to overlap on the inlet / outlet mold-changing platform or storage side warehouse. At this point, although the AGV mold-changing trolley is some distance from the inlet / outlet mold-changing platform or storage side warehouse, the tilting support roller conveyor 808 and the tilting push-pull track 807 exist within this distance. This allows the mold to be moved using the tilting support roller conveyor 808. The mold can be moved from the AGV mold-changing trolley to the inlet / outlet mold-changing platform or storage side warehouse, or vice versa.

[0046] In this embodiment, the bottom of the second machine platform 801 is provided with a traveling wheel 805 and an AGV navigation module. The bottom of the second machine platform 801 is also provided with a positioning column 806 and a positioning column 806 driving mechanism for driving the positioning column 806 to move up and down. A positioning block 10 that cooperates with the positioning column 806 is provided on the ground. The positioning block 10 has a positioning through hole in the middle for the positioning column 806 to be inserted.

[0047] Specifically, the above-mentioned AGV navigation module and AGV guide rail 9 work together to realize the automatic navigation operation of AGV mold changing trolley 8. When AGV mold changing trolley moves into position, the positioning column 806 drive mechanism drives the positioning column 806 to insert into the positioning through hole, ensuring the positioning accuracy of AGV mold changing trolley 8, and also ensuring the stability of AGV mold changing trolley 8 when performing mold changing operation.

[0048] In this embodiment, as Figure 5As shown, the first storage side warehouse 4, the second storage side warehouse 5, the third storage side warehouse 6 and the fourth storage side warehouse 7 all include a third machine platform 401. The third machine platform 401 is provided with multiple rows of third support roller conveyors 402. The third machine platform 401 is provided with third guardrails 403 on both sides. Multiple third guide rollers are provided on the inner side of the third guardrails 403. The third machine platform 401 is provided with lifting side guards 404 at both the front and rear ends.

[0049] In actual operation, the third support roller 402 in the above structure can ensure the smoothness of mold pulling out and feeding, while the third guide roller can ensure the smoothness of mold movement and play a guiding role. At the same time, the lifting side guard 404 can prevent the mold from falling.

[0050] This invention also discloses a mold changing method for an AGV (Automated Guided Vehicle) for an edge banding machine. When a mold changing operation is required, the AGV mold changing trolley moves along the AGV guide rail 9 to the corresponding storage side of the edge banding machine. The AGV mold changing trolley pulls the mold on the storage side of the edge banding machine to the adjacent infeed / outfeed mold changing platform. The two infeed / outfeed mold changing platforms start simultaneously. One infeed / outfeed mold changing platform pulls out the old mold from the edge banding machine 1, and the other infeed / outfeed mold changing platform sends the new mold into the edge banding machine 1. The AGV mold changing trolley 8 moves along the AGV guide rail 9 to the infeed / outfeed mold changing platform corresponding to the old mold, pulls the old mold onto the AGV mold changing trolley, and moves along the AGV guide rail 9 to an empty storage side banding machine to store the mold.

[0051] This system enables simultaneous entry and exit of molds through two mold changing tables, reducing the actual mold exchange time to 30 seconds. It also employs multiple storage bins to reduce the retrieval time of the bins. Furthermore, when the number of mold bins increases, the AGV mold changing trolley can also be used as a turnover vehicle.

[0052] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
