Description

Technical Field

[0001] This utility model relates to the technical field of rubber extrusion composite production line, specifically to an automatic feeding and discharging system for a multi-station winding device. Background Technology

[0002] With the advancement of the global Industry 4.0 wave, automation and intelligent technologies have been widely applied in the rubber extrusion industry. As a crucial component of the manufacturing sector, the rubber extrusion industry is increasingly demanding automation and intelligent technologies in its material handling, storage, and management processes. Traditional manual handling methods are not only inefficient and costly but also pose safety hazards and risks of human error, failing to meet the demands of modern industrial production for high efficiency, precision, and safety. Automated Guided Vehicles (AGVs), as advanced automated logistics equipment, have gained increasing attention in the rubber extrusion industry in recent years. Through built-in sensors, controllers, and navigation systems, AGVs can autonomously navigate, avoid obstacles, and precisely transport materials to designated locations without human intervention. This automated handling method not only improves production efficiency and reduces labor costs but also significantly reduces human error and the occurrence of safety accidents.

[0003] In rubber extrusion compounding production lines, most companies use multi-station material handling trolleys to wind up materials. Some companies have gradually replaced forklifts with AGVs (Automated Guided Vehicles), avoiding tooling damage caused by forklift operator visibility issues and improving production efficiency. However, in existing technologies, directly connecting AGVs to the material handling trolleys at each winding station to move materials between areas requires at least one set of dedicated AGVs per production line to meet the material handling needs. The maximum operating speed of AGVs for material handling is usually designed based on the longest possible travel path and the maximum speed of the production line, which has the following shortcomings in actual production:

[0004] 1. During the long production preparation phase, such as preheating the extruder or changing product specifications on the coiling production line, the AGV carts are directly connected to each coiling station. The AGV carts can only prepare one set of material carts for each coiling station in advance for use. The remaining time is spent parked around the coiling station waiting for the coiling station to be full of material before starting the transportation work. The time during the production preparation phase cannot be used reasonably, and the utilization efficiency of the AGV carts during the production preparation phase is extremely low.

[0005] 2. The production line extrudes and rolls products of various specifications, and the production speed of each rolled product is different. The production speed of most products is lower than the maximum production speed, and the production speed of some products can only reach 40% of the maximum production speed. In this case, due to the limitation of the production line speed, the AGV cart can only return to the side of the winding station after completing each transport work and wait for the winding station to be full of material before it can start the transport work. The utilization efficiency of the AGV cart under the low speed operation of the production line is very low.

[0006] 3. During the multi-station winding process, the AGV needs to transport the material cart filled with semi-finished products from the extrusion area to the forming area during each station switching time. At the same time, it also needs to transport the material cart from the storage area to the winding station. Since the locations of each transport point are different, the length of the AGV's travel trajectory is also different. In most cases, the length of the AGV's travel trajectory is shorter than the longest travel trajectory. In this case, after completing each transport task, the AGV can only return to the side of the winding station and wait for the winding station to be filled with material before it can start transporting again. The utilization efficiency of the AGV in short trajectory routes is relatively low.

[0007] 4. Multiple extrusion composite production lines are usually arranged in the extrusion area. Each production line is equipped with at least one AGV special vehicle. For situations with high production speed and long running trajectory, two AGV special vehicles need to be configured. When multiple production lines are producing at the same time, multiple AGV vehicles will frequently move back and forth in the extrusion area, which seriously occupies the production space.

[0008] Therefore, how to improve the utilization efficiency of AGVs in the winding device and reduce the number of AGVs used in the winding device has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0009] In view of the shortcomings of the existing technology, this utility model provides an automatic feeding and discharging system for a multi-station winding device, which aims to improve the utilization efficiency of AGV trolleys in the winding device and reduce the number of AGV trolleys used in the winding device.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] An automatic feeding and discharging system for a multi-station winding device includes a winding conveyor belt and multiple winding stations. The winding conveyor belt runs through the top of the multiple winding stations. Each winding station uses a material trolley-type winding device to wind up the material. The system is characterized by: multiple winding stations including a #1 winding station and a #2 winding station; a material trolley feeding and discharging channel composed of multiple sets of linear conveyors, stacking conveyors, and rotary conveyors surrounding the #1 and #2 winding stations; the feeding and discharging channels being arranged in an H-shape; each of the multiple sets of linear conveyors, stacking conveyors, and rotary conveyors including a material trolley conveying device; the stacking conveyor can store multiple sets of material trolleys; and the rotary conveyor can drive the material trolley conveying device to rotate. The feeding and discharging channels include a trolley feeding channel, a trolley reciprocating channel, and a trolley discharging channel. The trolley feeding channel includes a feeding linear conveyor and a feeding stacking conveyor connected to each other. The trolley reciprocating channel includes a #1 station rotary conveyor and a #2 station rotary conveyor connected to the #1 winding station and the #2 winding station respectively, a feeding rotary conveyor connected to the feeding stacking conveyor, a #1 station linear conveyor located between the #1 station rotary conveyor and the #2 station rotary conveyor, and a #2 station linear conveyor located between the #2 station rotary conveyor and the feeding rotary conveyor. The trolley discharging channel includes a discharging linear conveyor, a discharging stacking conveyor, a discharging rotary conveyor, and a transition linear conveyor connected in sequence, wherein the transition linear conveyor is perpendicularly connected to the feeding rotary conveyor, and the discharging linear conveyor is arranged in the same direction as the feeding linear conveyor.

[0012] Furthermore, the connections between the multiple sets of linear conveying devices, stacking conveying devices, and rotary conveying devices are all arc-shaped. The two sides of the linear conveying device are concave arc-shaped, the side of the stacking conveying device connected to the linear conveying device is convex arc-shaped, the side of the stacking conveying device connected to the rotary conveying device is concave arc-shaped, and the rotary conveying device is a complete circle.

[0013] Furthermore, the rotary conveying device includes a base assembly, a rotary table assembly, and a rotary drive device. The rotary drive device includes a rotary table geared motor and a rotary reducer. The rotary reducer includes a fixed ring fixed on the base assembly, an input shaft connected to the rotary table geared motor, and a rotating ring perpendicularly connected to the bottom center of the rotary table assembly. The input shaft has a worm gear, and the rotating ring has a worm wheel. The worm gear and the worm wheel mesh with each other. When the input shaft rotates, it can drive the rotating ring to rotate within the fixed ring, thereby driving the trolley conveying device above the rotary table assembly to rotate.

[0014] Furthermore, the material trolley conveying device adopts a double-row top plate roller chain to convey the material trolley. The double-row top plate roller chain has an n-shaped chain plate, a rubber top plate is provided above the n-shaped chain plate, and a support plate is provided below the double-row top plate roller chain.

[0015] Furthermore, at least three sets of material trolleys can be stored on the feeding stacking conveyor and the discharging stacking conveyor respectively.

[0016] Furthermore, the feeding stacking conveyor and the discharging stacking conveyor are each equipped with a number of photoelectric detection switches equal to the number of material storage trolleys. The feeding linear conveyor and the discharging linear conveyor are each equipped with one set of photoelectric detection switches. All photoelectric detection switches are communicatively connected to the AGV trolley.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By utilizing the feeding stacking conveyor device, which has the function of storing multiple material carts, the AGV cart can complete the storage of multiple sets of material carts during the production preparation stage of the coiling production line, such as the preheating of the extruder or the change of product specifications, so that they can be used at the coiling station. This greatly improves the utilization efficiency of AGV carts during the production preparation stage.

[0019] 2. By utilizing the feeding and discharging stacking conveyors, which can store multiple material carts, AGVs can quickly store multiple sets of material carts on the feeding stacking conveyor within a concentrated time period. Alternatively, AGVs can start rapid and centralized transportation only after multiple sets of material carts have been stacked on the discharging stacking conveyor. The way AGVs transport material carts changes from distributed to centralized. AGVs can quickly transport material carts without being affected by the production line speed, and they do not need to stop and wait at the winding station due to short travel distances. This effectively converts the waiting time of AGVs in the existing technology into the transportation time for feeding and discharging, thus greatly improving the utilization efficiency of AGVs.

[0020] 3. When producing on a single production line, only one AGV cart is needed to handle the material handling tasks, freeing up extra time to assist in other handling tasks. When multiple extrusion composite production lines are producing simultaneously, the AGV cart can assist in handling tasks on adjacent production lines. Two AGV carts can be used to handle the handling tasks on three production lines, reducing the number of AGV carts by at least 30%. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] The multi-station winding device automatic feeding and discharging system provided by this utility model, such as Figure 1 , Figure 2As shown, the device includes a winding conveyor belt 3 and multiple winding stations. The winding conveyor belt 3 runs through the top of the multiple winding stations. Each winding station uses a material trolley-type winding device to wind up the material. The device is characterized in that: the multiple winding stations include winding station 1# and winding station 2#. Around winding station 1# and winding station 2#, there is a material trolley inlet / outlet channel composed of multiple sets of linear conveying devices, stacking conveying devices, and rotary conveying devices. The multiple sets of linear conveying devices include a feeding linear conveyor 401, a winding conveyor 402 for station 1#, and a winding conveyor 403 for station 2#. 3. A discharge linear conveyor 404 and a transition linear conveyor 405; multiple sets of stacking conveyors including a feeding stacking conveyor 501 and a discharge stacking conveyor 502; multiple sets of rotary conveyors including a #1 station rotary conveyor 601, a #2 station rotary conveyor 602, a feeding rotary conveyor 603, and a discharge rotary conveyor 604; the feeding and discharging channels are arranged in an H-shape; each of the multiple linear conveyors, stacking conveyors, and rotary conveyors includes a material trolley conveyor 7; the stacking conveyor can store multiple sets of material trolleys. The rotary conveyor can drive the material trolley conveyor 7 to rotate. The inlet and outlet channels include a trolley inlet channel, a trolley reciprocating channel, and a trolley outlet channel. The trolley inlet channel includes an inlet linear conveyor 401 and an inlet stacking conveyor 501 connected to each other. The trolley reciprocating channel includes a rotary conveyor 601 for station 1 and a rotary conveyor 602 for station 2, which are respectively connected to station 1 and station 2, an inlet rotary conveyor 603 connected to the inlet stacking conveyor 501, and a rotary conveyor 603 located at station 1 and station 2. The linear conveyor 402 at station 1, located between the rotary conveyor 602 at station 2 and the rotary conveyor 602 at station 2, and the linear conveyor 403 at station 2, located between the rotary conveyor 602 at station 2 and the rotary conveyor 603 at station 2, are described in the trolley discharge channel. The trolley discharge channel includes a discharge linear conveyor 404, a discharge stacking conveyor 502, a discharge rotary conveyor 604, and a transition linear conveyor 405 connected in sequence. The transition linear conveyor 405 is perpendicularly connected to the rotary conveyor 603 at station 2, and the discharge linear conveyor 404 is arranged in the same direction as the rotary conveyor 401 at station 2.

[0028] In the above embodiments, when the material trolley is fed, the AGV trolley transports the material trolley to the feeding linear conveyor 401. The material trolley is then transported to the feeding stacking conveyor 501 via the feeding linear conveyor 401. Each time a material trolley enters the feeding stacking conveyor 501, the feeding stacking conveyor 501 can move the material trolley a distance equal to the length of the material trolley in the direction of the winding station, thereby realizing the function of arranging and storing multiple material trolleys sequentially on the feeding stacking conveyor 501. When the material trolley is discharged, the discharge rotary conveyor 604 transports the material trolley to the discharge stacking conveyor 502. Each time a material trolley enters the discharge stacking conveyor 502, the discharge stacking conveyor 502 can move the material trolley a distance equal to the length of the material trolley in the opposite direction of the winding station, thereby realizing the function of arranging and storing multiple material trolleys sequentially on the discharge stacking conveyor 502.

[0029] In the above embodiments, the feeding stacking conveyor 501 has the function of storing multiple material carts. The AGV carts can complete the storage of multiple sets of material carts during the production preparation stage of preheating the extruder in the winding production line, or during the production preparation stage of cleaning the extruder head rubber material and changing the die shape when changing product specifications, so that they can be used at the winding station. This greatly improves the utilization efficiency of AGV carts in the production preparation stage.

[0030] In the above embodiments, the feeding stacking conveyor 501 and the discharging stacking conveyor 502 have the function of storing multiple material carts. The AGV cart can quickly store multiple sets of material carts on the feeding stacking conveyor 501 in a concentrated period of time, or it can start rapid centralized transportation only after multiple sets of material carts are piled up on the discharging stacking conveyor 502. This centralized transportation method of AGV carts can quickly transport material carts without being affected by the production line speed, and there is no need to stop and wait next to the winding station due to the short travel trajectory. It effectively converts the waiting time of AGV carts in the prior art into the transportation time for feeding and discharging. After the AGV carts have completed the centralized transportation of material carts, they can also use the interval time to assist in completing other material transportation tasks, which fully improves the utilization efficiency of AGV carts.

[0031] In another embodiment of this utility model, in order to shorten the length of the material trolley's inlet and outlet channels and reduce the floor space occupied, such as... Figure 2 As shown, the connections between the multiple sets of linear conveying devices, stacking conveying devices, and rotary conveying devices are all arc-shaped. The two sides of the linear conveying device are concave arc-shaped, the side of the stacking conveying device connected to the linear conveying device is convex arc-shaped, the side of the stacking conveying device connected to the rotary conveying device is concave arc-shaped, and the rotary conveying device is a complete circle.

[0032] In another embodiment of this utility model, such as Figure 3 As shown, the rotary conveying device includes a base assembly 611, a rotary table assembly 612, and a rotary drive device. The rotary drive device includes a rotary table geared motor 614 and a rotary reducer. The rotary reducer includes a fixed ring 613 fixed on the base assembly 611, an input shaft 615 connected to the rotary table geared motor 614, and a rotating ring 616 perpendicularly connected to the bottom center of the rotary table assembly 612. The input shaft 615 has a worm gear, and the rotating ring 616 has a turbine. The worm gear and the turbine mesh with each other. When the input shaft 615 rotates, it can drive the rotating ring 616 to rotate within the fixed ring 613, thereby driving the trolley conveying device 7 above the rotary table assembly 612 to rotate.

[0033] In the above embodiments, the rotary drive device adopts a rotary reducer, which can effectively compress the height space of the rotary table assembly 612 and the base assembly 611, making the structure of the rotary conveyor more compact. It can reduce the overall height of the material trolley's inlet and outlet channels, and avoid the phenomenon of the material trolley falling due to its center of gravity being too high when the inlet linear conveyor 401 and outlet linear conveyor 404 are docked with the AGV trolley.

[0034] In another embodiment of this utility model, such as Figures 2 to 4 As shown, all linear conveyors, stacking conveyors, and rotary conveyors use a double-row top plate roller chain 701 to transport material trolleys. The specific implementation of the material trolley conveying device 7 is as follows: The material trolley conveying device 7 includes conveying supports on both sides, a conveying reduction motor, and a synchronous drive shaft. The conveying reduction motor is fixed to the conveying supports, and the synchronous drive shaft is fixed to the conveying supports on both sides via bearing seats. Drive sprockets are provided on both sides of the synchronous drive shaft. The drive sprockets are connected to the conveying sprocket groups on the conveying supports on both sides via the double-row top plate roller chain 701. The conveying sprocket group includes a driving chain and a driven sprocket installed at the same horizontal height. A supporting double-row top plate roller chain is provided below the chain between the driving sprocket and the driven sprocket. The chain 701 has a pallet 704, which is fixed on the conveyor support. The double-row top plate roller chain 701 has an n-shaped chain plate 702, and a rubber top plate 703 is provided above the n-shaped chain plate 702. In the linear conveying device, the conveyor supports on both sides of the material trolley conveying device 7 are fixedly connected to the frame of the linear conveying device. In the stacking conveying device, the conveyor supports on both sides of the material trolley conveying device 7 are fixedly connected to the frame of the stacking conveying device. In the rotary conveying device, the conveyor supports on both sides of the material trolley conveying device 7 are fixedly connected to the rotary table assembly 612 in the rotary conveying device.

[0035] In the above embodiments, when the material trolley conveying device 7 is working, the conveying reduction motor drives the synchronous transmission shaft to rotate. The transmission sprockets on both sides of the synchronous transmission shaft drive the double-row top plate roller chain 701 to rotate on the driving chain and driven sprockets on the conveying sprocket set. The conveying function of the material trolley is realized through the friction formed by the contact between the rubber top plate 703 above the double-row top plate roller chain 701 and the lower surface of the material trolley frame. In this embodiment, the pallet 704 is placed below the double-row top plate roller chain 701, which can reduce the friction between the double-row top plate roller chain 701 and the conveying supports on both sides. The pallet 704 is made of wear-resistant nylon material, which can reduce the friction between the double-row top plate roller chain 701 and the pallet 704 and improve the transmission efficiency. In addition, the use of the rubber top plate 703 can increase the contact area of ​​the transmission parts and the friction of the transmission, thereby improving the stability and reliability of the material trolley conveying process.

[0036] In another embodiment of this utility model, at least three sets of material trolleys can be stored on the feeding stacking conveyor 501 and the discharging stacking conveyor 502 respectively.

[0037] In the above embodiments, the number of material trolleys stored on the feeding stacking conveyor 501 and the discharging stacking conveyor 502 can be designed according to the needs of a single production line or multiple production lines operating simultaneously. If the number of trolleys stored is less than two, the redundant time freed up by the AGV trolleys is short and cannot assist in completing other handling tasks.

[0038] In another embodiment of this utility model, photoelectric detection switches are provided on the feeding stacking conveyor 501 and the discharging stacking conveyor 502, with the number of photoelectric detection switches equal to the number of material storage trolleys. One set of photoelectric detection switches is provided on the feeding linear conveyor 401 and the discharging linear conveyor 404. All photoelectric detection switches are communicatively connected to the electrical control system and the control system built into the AGV trolley.

[0039] In the above embodiments, the signal from the photoelectric detection switch allows the electrical control system and the control system built into the AGV to identify the quantity and location information of the material storage carts, facilitating the automation and intelligence of the entire feeding and discharging system.

[0040] Before production begins on the rubber extrusion compounding production line, the extruder needs to be preheated for approximately one hour. During this preheating phase, the electrical control system of the multi-station winding device's automatic feeding and discharging system and the associated AGV (Automated Guided Vehicle) control system are activated. The AGV transports the material cart from the storage area to the extrusion area and places it on the feeding linear conveyor 401. Since no material carts are installed at winding stations 1 and 2, the first material cart sequentially passes through the feeding linear conveyor 401, the feeding stacking conveyor 501, the feeding rotary conveyor 603, the 2# station linear conveyor 403, the 2# station rotary conveyor 602, and the 1# station linear conveyor 402 before reaching the 1# station rotary conveyor 601. After the 1# station rotary conveyor 601 rotates 90°, the first material cart enters... The first material cart enters the No. 1 winding station 1; the second material cart passes through the feeding linear conveyor 401, the feeding stacking conveyor 501, the feeding rotary conveyor 603, and the No. 2 station linear conveyor 403 in sequence, and then reaches the No. 2 station rotary conveyor 602. After the No. 2 station rotary conveyor 602 rotates 90°, the second material cart enters the No. 2 winding station 2; after material carts are detected at both the No. 1 winding station 1 and the No. 2 winding station 2, the second and subsequent material carts pass through the feeding linear conveyor 401 and reach the feeding stacking conveyor 501, and then begin to be arranged in sequence until the feeding stacking conveyor 501 is full of material carts. At this point, the AGV can also transport the last material cart and place it on the feeding linear conveyor 401. Based on the calculation that the feeding stacking conveyor 501 can store 3 sets of material carts, the AGV cart transported a total of 6 material carts. The round-trip time for each material cart transport can be set to 10 minutes. During the preheating stage, the AGV cart has completed the storage of all material carts at the same time. Only when the feeding stacking conveyor 501 sends a transport signal to the AGV cart will the AGV cart start the next round of material cart transport tasks.

[0041] After the winding station of the rubber extrusion compounding production line is put into operation, the AGV trolley does not need to wait on the original production line. It can assist in completing other material handling tasks and can also assist adjacent production lines in completing material handling tasks. After the material trolley at winding station 1 is fully wound with material, the rotary conveyor 601 at winding station 1 rotates 90° to dock with winding station 1. When the material trolley at winding station 1 is completely placed on the rotary conveyor 601, the rotary conveyor 601 rotates 90° to dock with the linear conveyor 402 at winding station 1. The material trolley then passes through rotary conveyor 602 at winding station 2 and linear conveyor 403 at winding station 2 in sequence to reach the feeding rotary conveyor 603. The feeding rotary conveyor 603 rotates 90° to dock with the transition linear conveyor. The feeding device 405 docks, and the discharge rotary conveyor 604 rotates 90° to dock with the transition linear conveyor 405. After the material trolley arrives at the discharge rotary conveyor 604, the discharge rotary conveyor 604 rotates 90° again to transport the material trolley to the discharge stacking conveyor 502. The material trolleys are arranged in sequence. Then, the No. 1 winding station 1 sends a signal to the material trolley. The feeding stacking conveyor 501 pushes one material trolley in the winding direction. The material trolley enters the No. 1 winding station 1 according to the travel path of the first material trolley in the preheating stage. Similarly, after the material trolley at the #2 winding station is full of material, the trolley will sequentially pass through the #2 station rotary conveyor 602, the #2 station linear conveyor 403, the transition linear conveyor 405, and the discharge rotary conveyor 604 to reach the discharge stacking conveyor 502, arranging the material trolleys in sequence. Then, the #2 winding station 2 sends a signal to the material trolleys, and the feeding stacking conveyor 501 pushes another material trolley in the winding direction. The material trolley enters the #2 winding station 2 according to the travel path of the second material trolley in the preheating stage. This process repeats until both the feeding and discharging stacking conveyor 502 and the discharge linear conveyor 404 are full of material trolleys. At this point, the discharge linear conveyor 404 sends a transport signal to the AGV, and the AGV begins to transport the material trolleys. Based on the calculation that the discharge stacking conveyor 502 can store 3 sets of material carts, including the 1 set of material carts stored on the discharge linear conveyor 404, a total of 4 sets of material carts are stored on the discharge channel. The switching time of each winding station is usually 15 minutes, and the storage time of the material carts is about 1 hour. That is, the AGV cart can use 1 hour to assist in completing other handling tasks, which greatly improves the utilization efficiency of the AGV cart.

[0042] When the AGV returns to the original production line for material handling, the material cart can be moved from the discharge linear conveyor 404 to the forming area, and simultaneously moved from the storage area to the feed linear conveyor 401. Since the AGV's travel speed is not affected by the production line speed or the winding station switching rhythm, the AGV can quickly complete the material handling task. The round-trip time for each material handling can be set to 10 minutes. Since the winding station switching time is usually 15 minutes, after 2 hours in the production process, the AGV can again fill 4 sets of material carts on the feed stacking conveyor 501 and the feed linear conveyor 401. The AGV can then use the redundant 1 hour to assist in completing other handling tasks. In this way, when 3 extrusion composite production lines are in operation simultaneously, 2 AGVs can be used to complete the material handling task, reducing the number of AGVs by at least 30%.

[0043] When the specifications of the rubber extrusion compounding production line need to be changed, the rubber material in the extruder head needs to be cleaned and the extruder nozzle needs to be changed. This process takes about 45 minutes to 1 hour. During this period, the AGV can transport the material cart to the feeding stacking conveyor 501 and the feeding linear conveyor 401 for storage, which improves the utilization efficiency of the AGV.
