Description

Technical Field

[0001] The invention relates to the technical field of rubber extrusion composite production line, in particular to an automatic feeding and discharging system of a multi-station winding device. Background Art

[0002] With the advancement of the global wave of Industry 4.0, automation and intelligent technologies have been widely used in the rubber extrusion industry. As an important part of the manufacturing industry, the rubber extrusion industry has an increasing demand for automation and intelligent technologies in the material handling, storage and management links in its production process. The traditional manual handling method is not only inefficient and costly, but also has safety hazards and the risk of human error, which makes it difficult to meet the needs of modern industrial production for efficiency, precision and safety. As an advanced automated logistics equipment, the application of automatic guided vehicles (AGVs) in the rubber extrusion industry has gradually received attention in recent years. Through built-in sensors, controllers and navigation systems, AGVs can autonomously navigate, avoid obstacles, and accurately 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 the occurrence of human errors and safety accidents.

[0003] In rubber extrusion compounding production lines, most companies use material cart-type multi-station winding devices to wind materials. Some companies have gradually adopted AGV carts instead of forklifts, avoiding damage to tooling due to forklift workers' line of sight problems and improving production efficiency. However, in the existing technology, the AGV cart is directly connected to the material cart at each winding station to realize the transportation of the material cart between various areas. Each production line needs to be equipped with more than one set of AGV special carts to meet the transportation needs of the material cart. The maximum operating speed of the AGV cart for transporting materials is usually designed according to the longest operating track and the maximum speed of the production line. In actual production, there are the following shortcomings:

[0004] 1. In the long production preparation stage of the coiling production line, such as preheating the extruder or changing product specifications, the AGV car is directly connected to each coiling station. The AGV car can only prepare one set of material carts for each coiling station in advance for standby use. The rest of the time it will be parked around the coiling station and wait for the coiling station to be full of materials before starting the handling work. It is impossible to reasonably use the time of the production preparation stage, and the utilization efficiency of the AGV car in the production preparation stage is extremely low;

[0005] 2. There are many specifications of extruded coiled products on the production line. The production speed of each coiled 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, the AGV car is restricted by the speed of the production line. After completing each handling work, the AGV car can only return to the coiling station and wait for the coiling station to be full of materials before it can start handling work. The utilization efficiency of the AGV car is very low when the production line runs at a low speed;

[0006] 3. In the multi-station winding process, the AGV needs to transport the material cart full of semi-finished products from the extrusion area to the molding area within the switching time of each station, and at the same time, it needs to transport the material cart from the storage area to the winding station. Due to the different locations of each transportation point, the length of the AGV's walking track is also different. In most cases, the length of the AGV's walking track is shorter than the longest running track. In this case, after completing each transportation work, the AGV can only return to the winding station and wait for the winding station to be full of materials before it can start the transportation work. The utilization efficiency of the AGV in the short track route is relatively low;

[0007] 4. In the extrusion area, multiple extrusion composite production lines are usually arranged. Each production line is equipped with at least one set of AGV special carts. For occasions with fast production speed and long running track, two AGV special carts are required. When multiple production lines are producing at the same time, multiple sets of AGV carts will frequently travel in the extrusion area, seriously occupying the production site.

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

[0009] In view of the shortcomings of the prior art, the present invention provides an automatic feeding and discharging system for a multi-station winding device, aiming to improve the utilization efficiency of the AGV trolley in the winding device and reduce the number of AGV trolleys used in the winding device.

[0010] To achieve the above object, the present invention provides the following technical solutions:

[0013] Furthermore, the rotating conveying device includes a base assembly, a rotating table assembly and a rotating drive device, the rotating drive device includes a rotating table reduction motor and a rotary reducer, the rotary reducer includes a fixed ring fixed on the base assembly, an input shaft connected to the rotating table reduction motor, and a rotating ring vertically connected to the bottom center of the rotating table assembly, the input shaft has a worm, and the rotating ring has a turbine, the worm and the turbine are meshed with each other, and when the input shaft rotates, it can drive the rotating ring to rotate in the fixed ring, thereby driving the trolley conveying device above the rotating 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 feed stacking conveying device and the discharge stacking conveying device respectively.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The feed stacking and conveying device has the function of storing multiple material carts. The AGV can store multiple sets of material carts in the long-term production preparation stage such as preheating the extruder of the coiling production line or changing product specifications, so as to prepare them for use at the coiling station, which greatly improves the utilization efficiency of the AGV in the production preparation stage;

[0019] 2. The infeed stacking conveyor and the outfeed stacking conveyor have the function of storing multiple material carts. The AGV can quickly store multiple sets of material carts on the infeed stacking conveyor in a concentrated period of time, and the AGV can only start to quickly and centrally transport the material carts after the outfeed stacking conveyor is full of multiple sets of material carts. The way in which the AGV transports the material carts is changed from distributed to centralized. The AGV can quickly transport the material carts without being affected by the speed of the production line, and there is no need to stop and wait at the winding station due to the short walking track. The waiting time of the AGV in the existing technology is effectively converted into the transport time of the infeed and outfeed materials, which fully improves the utilization efficiency of the AGV.

[0020] 3.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0027] The automatic feeding and discharging system of the multi-station winding device provided by the present invention is as follows: Figure 1 , Figure 2As shown, it includes a winding conveyor belt 3 and multiple winding stations, the winding conveyor belt 3 runs through the tops of the multiple winding stations, and the winding stations all use material trolley-type winding devices to wind the materials. It is characterized in that: the multiple winding stations include 1# winding station 1 and 2# winding station 2, and material trolley inlet and outlet channels composed of multiple sets of linear conveying devices, stacking conveying devices, and rotating conveying devices are arranged around the 1# winding station 1 and the 2# winding station 2, wherein the multiple sets of linear conveying devices include a feed linear conveying device 401, a 1# station linear conveying device 402, and a 2# station linear conveying device 40 3. a discharging linear conveying device 404 and a transition linear conveying device 405, a plurality of stacking conveying devices including a feeding stacking conveying device 501 and a discharging stacking conveying device 502, a plurality of rotating conveying devices including a 1# station rotating conveying device 601, a 2# station rotating conveying device 602, a feeding rotating conveying device 603 and a discharging rotating conveying device 604, the feeding and discharging channels are arranged in an H shape, the plurality of linear conveying devices, the stacking conveying devices and the rotating conveying devices all include a material trolley conveying device 7, the stacking conveying device can store a plurality of material trolleys, the The rotating conveying device can drive the material trolley conveying device 7 to rotate, and the inlet and outlet channels include a trolley feeding channel, a trolley reciprocating channel and a trolley discharging channel. The trolley feeding channel includes a feed linear conveying device 401 and a feed stacking conveying device 501 connected to each other, and the trolley reciprocating channel includes a 1# station rotating conveying device 601 and a 2# station rotating conveying device 602 connected to the 1# winding station 1 and the 2# winding station 2 respectively, a feed rotating conveying device 603 connected to the feed stacking conveying device 501, and a rotating conveying device 601 located at the 1# station rotating conveying device and The 1# station linear conveying device 402 is located between the 2# station rotary conveying device 602, and the 2# station linear conveying device 403 is located between the 2# station rotary conveying device 602 and the feed rotary conveying device 603. The trolley discharging channel includes a discharging linear conveying device 404, a discharging stacking conveying device 502, a discharging rotary conveying device 604 and a transition linear conveying device 405 connected in sequence, wherein the transition linear conveying device 405 is vertically connected to the feed rotary conveying device 603, and the discharging linear conveying device 404 is arranged in the same direction as the feed linear conveying device 401.

[0028] In the above embodiment, when the material cart is feeding, the AGV cart transports the material cart to the feeding linear conveyor 401, and the material cart is transported to the feeding stacking conveyor 501 through the feeding linear conveyor 401. Each time a material cart enters the feeding stacking conveyor 501, the feeding stacking conveyor 501 can drive the material cart to move a distance of the material cart length in the direction of the winding station, thereby realizing the function of multiple material carts being arranged and stored in sequence on the feeding stacking conveyor 501; when the material cart is discharging, the discharging rotary conveyor 604 transports the material cart to the discharging stacking conveyor 502. Each time a material cart enters the discharging stacking conveyor 502, the discharging stacking conveyor 502 can drive the material cart to move a distance of the material cart length in the opposite direction of the winding station, thereby realizing the function of multiple material carts being arranged and stored in sequence on the discharging stacking conveyor 502.

[0029] In the above embodiment, the feed stacking and conveying device 501 has the function of storing multiple material carts. The AGV can complete the storage of multiple sets of material carts in the production preparation stage of preheating the extruder of the winding production line, or in the production preparation stage of cleaning the rubber material of the extruder head and changing the die when changing the product specifications, so as to prepare for the winding station, thereby greatly improving the utilization efficiency of the AGV in the production preparation stage;

[0030] In the above embodiment, the feed stacking conveyor 501 and the discharge stacking conveyor 502 have the function of storing multiple material carts. The AGV cart can quickly store multiple sets of material carts on the feed stacking conveyor 501 in a concentrated time period, or start rapid centralized transportation only after multiple sets of material carts are piled up on the discharge stacking conveyor 502. This centralized transportation method of the AGV cart can quickly transport the material cart without being affected by the speed of the production line, and there is no need to stop and wait at the winding station due to the short walking trajectory. The waiting time of the AGV cart in the prior art is effectively converted into the transportation time of the feed and discharge materials. After the AGV cart has concentratedly transported the material carts, it can also use the interval time period to assist in completing other material handling tasks, thereby fully improving the utilization efficiency of the AGV cart.

[0031] In another embodiment of the present invention, in order to shorten the length of the material inlet and outlet passage of the material cart and reduce the floor space, as Figure 2 As shown, the connections between the multiple sets of linear conveying devices, stacking conveying devices, and rotating conveying devices are all arc-shaped, wherein both sides of the linear conveying device are concave arc-shaped, the side where the stacking conveying device is connected to the linear conveying device is a convex arc-shaped, the side where the stacking conveying device is connected to the rotating conveying device is a concave arc-shaped, and the outer shape of the rotating conveying device is a full circle.

[0032] In another embodiment of the present invention, Figure 3 As shown, the rotating conveying device includes a base assembly 611, a rotating table assembly 612 and a rotating drive device, the rotating drive device includes a rotating table reduction 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 rotating table reduction motor 614, and a rotating ring 616 vertically connected to the bottom center of the rotating table assembly 612, the input shaft 615 has a worm, and the rotating ring 616 has a turbine, the worm and the turbine are meshed with each other, and when the input shaft 615 rotates, it can drive the rotating ring 616 to rotate in the fixed ring 613, thereby driving the trolley conveying device 7 above the rotating table assembly 612 to rotate.

[0033] In the above embodiment, the rotary drive device adopts a rotary reducer, which can effectively compress the height space between the rotating table assembly 612 and the base assembly 611, making the structure of the rotating conveying device more compact, and can reduce the overall height of the material cart inlet and outlet channels, thereby preventing the material cart from falling due to the center of gravity being too high when the feed linear conveying device 401 and the discharge linear conveying device 404 are docked with the AGV cart.

[0034] In another embodiment of the present invention, Figures 2 to 4 As shown, the material trolley conveying device 7 on all linear conveying devices, stacking conveying devices, and rotating conveying devices adopts a double-row top plate roller chain 701 to convey the material trolley. The specific implementation of the material trolley conveying device 7 is that the material trolley conveying device 7 includes conveying brackets on both sides, a conveying reduction motor, and a synchronous transmission shaft. The conveying reduction motor is fixed on the conveying bracket, and the synchronous transmission shaft is fixed on the conveying brackets on both sides through a bearing seat. Transmission sprockets are provided on both sides of the synchronous transmission shaft. The transmission sprockets are respectively connected to the conveying sprocket groups on the conveying brackets on both sides through a double-row top plate roller chain 701. The conveying sprocket group includes a driving chain and a passive sprocket installed at the same horizontal height. A supporting double-row top plate roller is provided below the chain between the driving sprocket and the passive sprocket. The support plate 704 of the chain 701 is fixed on the conveying bracket, 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 conveying brackets 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 conveying brackets on both sides of the material trolley conveying device 7 are fixedly connected to the frame of the stacking conveying device. In the rotating conveying device, the conveying brackets on both sides of the material trolley conveying device 7 are fixedly connected to the rotating table assembly 612 in the rotating conveying device.

[0035] In the above embodiment, when the material trolley conveying device 7 is working, the conveying reduction motor drives the synchronous transmission shaft to rotate, and the transmission sprockets on both sides of the synchronous transmission shaft drive the double-row top plate roller chain 701 to rotate on the active chain and the passive sprocket on the conveying sprocket group, and 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 is realized to realize the conveying function of the material trolley. In this embodiment, the support plate 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 brackets on both sides. The support plate 704 is made of wear-resistant nylon material, which can reduce the friction between the double-row top plate roller chain 701 and the support plate 704, and improve the transmission efficiency. In addition, the use of the rubber top plate 703 can increase the contact area of ​​the transmission part and the friction of the transmission, thereby improving the stability and reliability of the material trolley conveying process.

[0036] In another embodiment of the present invention, at least three sets of material trolleys can be stored on the feed stacking conveyor device 501 and the discharge stacking conveyor device 502 respectively.

[0037] In the above embodiment, the number of material carts stored on the feed stacking conveyor 501 and the discharge stacking conveyor 502 can be designed according to the needs of a single production line or multiple production lines producing at the same time. If the number of stored carts is less than 2 sets, the redundant time freed up by the AGV cart is short and cannot assist in completing other handling tasks.

[0038] In another embodiment of the present invention, a number of photoelectric detection switches equal to the number of material storage carts are provided on the feed stacking conveyor 501 and the discharge stacking conveyor 502, and a set of photoelectric detection switches are provided on the feed linear conveyor 401 and the discharge linear conveyor 404, respectively. All photoelectric detection switches are communicatively connected with the electrical control system and the built-in control system of the AGV cart.

[0039] In the above embodiment, the signal of the photoelectric detection switch can allow the electrical control system and the control system built into the AGV trolley to identify the number information and location information of the material storage trolleys, thereby facilitating the automation and intelligence of the entire material loading and unloading system.

[0040] Before the rubber extrusion composite production line needs to start production, the extruder of the production line needs to be preheated, and the preheating time is about 1 hour. During the preheating stage, the electrical control system of the automatic feeding and unloading system of the multi-station winding device and the supporting AGV trolley control system can be turned on. The AGV trolley transports the material trolley from the storage area to the extrusion area, and places the material trolley on the feed linear conveyor 401. Since the material trolley is not installed on the 1# winding station 1 and the 2# winding station 2, the first material trolley passes through the feed linear conveyor 401, the feed stacking conveyor 501, the feed rotary conveyor 603, the 2# station linear conveyor 403, the 2# station rotary conveyor 602, and the 1# station linear conveyor 402 to the 1# station rotary conveyor 601. After the 1# station rotary conveyor 601 rotates 90°, the first material trolley enters Enter 1# winding station 1; the second material trolley passes through the feed linear conveyor 401, the feed stacking conveyor 501, the feed rotary conveyor 603, the 2# station linear conveyor 403 and arrives at the 2# station rotary conveyor 602, and the 2# station rotary conveyor 602 rotates 90°, and the second material trolley enters the 2# winding station 2; after the material trolleys are detected at the 1# winding station 1 and the 2# winding station 2, the second and subsequent material trolleys pass through the feed linear conveyor 401 and arrive at the feed stacking conveyor 501, and then begin to be arranged in sequence until the feed stacking conveyor 501 is full of material trolleys, and the AGV trolley can also transport the last material trolley and place it on the feed linear conveyor 401. According to the calculation that the feed stacking conveyor device 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. The AGV cart will not start the next round of material cart transport tasks until the feed stacking conveyor device 501 sends a transport signal to the AGV cart.

[0041] After the coiling station of the rubber extrusion composite production line is put into production, the AGV car does not need to wait on the original production line, and can assist in completing other handling tasks, and can also assist adjacent production lines in completing handling tasks. After the 1# coiling station 1 is fully rolled up on the material trolley, the 1# station rotary conveyor device 601 rotates 90° and docks with the 1# coiling station 1. When the material trolley on the 1# coiling station 1 is completely placed on the 1# station rotary conveyor device 601, the 1# station rotary conveyor device 601 rotates another 90° and docks with the 1# station linear conveyor device 402. The material trolley passes through the 2# station rotary conveyor device 602 and the 2# station linear conveyor device 403 in turn to reach the feed rotary conveyor device 603. The feed rotary conveyor device 603 rotates 90° and docks with the transition linear conveyor device 402. The feeding stacking conveyor 501 pushes a material trolley in the winding direction, and the material trolley enters the 1# winding station 1 according to the walking channel of the first material trolley in the preheating stage. Similarly, after the 2# coiling station has fully rolled up the material trolley, the material trolley will 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, and arrange the material trolleys in sequence. Then the 2# coiling station 2 sends a signal for the material trolley, and the feed stacking conveyor 501 pushes another material trolley in the coiling direction. The material trolley enters the 2# coiling station 2 according to the walking channel of the second material trolley in the preheating stage. This process is repeated back and forth until the feed and discharge stacking conveyor 502 and the discharge linear conveyor 404 are fully loaded with material trolleys, and the discharge linear conveyor 404 sends a handling signal to the AGV trolley, and the AGV trolley starts to carry the material trolley. According to the calculation that the discharge stacking conveyor 502 can store 3 sets of material carts, including 1 set of material carts stored on the discharge linear conveyor 404, a total of 4 sets of material carts are stored in the discharge channel. The switching time of the winding station is usually 15 minutes each time, and the storage time of the material cart is about 1 hour, that is, the AGV cart can use 1 hour to assist in completing other handling tasks, which fully improves the utilization efficiency of the AGV cart.

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

[0043] When the rubber extrusion compounding production line needs to change specifications, it is necessary to clean the rubber material in the extruder head and replace the extruder die. This period takes about 45 minutes to 1 hour. During this period, the AGV can move the material cart to the feed stacking conveyor 501 and the feed linear conveyor 401 for storage in advance, thereby improving the utilization efficiency of the AGV.
