Description

Technical Field

[0001] This invention relates to a composite board production equipment, and more particularly to a rock wool strip feeding device for a composite board production line. Background Technology

[0002] Rock wool composite panels, also known as color steel composite panels, color steel sandwich panels, or color steel rock wool composite panels, are widely used in various steel structure buildings due to their advantages such as good fire resistance, strong thermal insulation, high load-bearing capacity, and flexible installation methods.

[0003] In the production process of rock wool composite panels, rock wool strips need to be laid on color steel plates coated with adhesive to clamp the rock wool strips between the two color steel plates. Chinese invention patent application CN115123768A describes a rock wool feeding device developed by the applicant. In essence, it is a rock wool strip feeding device for composite panel production lines. It includes a column and a platform. A panel conveying device is set below the platform. The platform is equipped with a feeding conveying device, a rock wool distributing device, a rock wool cutting and crossing device, and a continuous cotton device connected in sequence. The platform has a through hole running vertically. The continuous cotton device includes a continuous cotton frame and a continuous cotton conveying mechanism installed on the continuous cotton frame. The continuous cotton conveying mechanism is located directly above the panel conveying device and on the same vertical plane as the panel conveying device. The output end of the continuous cotton conveying mechanism passes through the through hole and is close to the conveying surface of the panel conveying device. Although the equipment can automatically feed rock wool strips, it requires a relatively complex rock wool sorting device, which results in relatively high equipment costs. Furthermore, because it needs to be installed on a platform above the panel conveying device of the composite board production line, and the platform is equipped with a sequentially connected feeding conveying device, rock wool sorting device, rock wool cutting and crossing device, and cotton continuing device, the equipment installation cycle is relatively long.

[0004] In view of this, the applicant has conducted an in-depth study on the structure of the rock wool strip feeding equipment used in the composite board production line, which led to this case. Summary of the Invention

[0005] The purpose of this invention is to provide a rock wool strip feeding device for composite board production lines with relatively low equipment cost and relatively short equipment installation cycle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rock wool strip feeding device for a composite board production line includes a horizontally arranged first crossbeam, a picking robot and an auxiliary robot horizontally slidably connected to the first crossbeam, and a material receiving station, a storage platform, a cotton continuing device, and a replenishment station arranged along the length of the first crossbeam. The material receiving station, the storage platform, and the cotton continuing device are all within the working range of the picking robot, and the storage platform, the cotton continuing device, and the replenishment station are all within the working range of the auxiliary robot.

[0008] As an improvement of the present invention, the material handling robot includes a swab-taking mechanism and an actuation component for moving the swab-taking mechanism. The actuation component includes a base horizontally slidably connected to the first crossbeam, a transverse motor for driving the base to slide, a lifting column vertically slidably connected to the base, a lifting motor for driving the lifting column to slide up and down, and a support frame installed at the lower end of the lifting column. There are multiple swab-taking mechanisms, which are arranged parallel to each other along the length of the support frame and slidably connected to the support frame. The support frame is also provided with a mechanism for adjusting the spacing between the swab-taking mechanisms. The adjusting mechanism, the cotton swab taking mechanism includes a slide block slidably connected to the support frame, a support rod fixedly connected to the slide block, and needle units fixedly connected to both ends of the support rod. The needle unit includes a mounting base fixedly connected to the corresponding support rod, two cylinders fixedly connected to the mounting base, and needle seats fixedly connected to the piston rods of each of the picking cylinders. On the two needle seats of the same needle unit, needles arranged parallel to the piston rods of the corresponding picking cylinders are fixedly connected to opposite sides.

The discharge end of the whole material conveyor, the storage platform, and the infeed end of the cotton feeding device are located on the same straight line.

[0011] As an improvement of the present invention, the unpacking and conveying device includes an unpacking frame, a driving roller and a driven roller arranged parallel to each other and rotatably connected to the unpacking frame, a conveyor motor for driving the driving roller to rotate, and a conveyor belt wound between the driving roller and the driven roller. A film cutting mechanism is provided on the side of the driving roller away from the driven roller and / or on the side of the driven roller away from the driving roller. The film cutting mechanism includes a lifting seat and a film cutting cylinder for driving the lifting seat to move up and down. A knife holder is fixedly connected to the lifting seat, and a cutter is detachably connected to the knife holder.

[0012] As an improvement of the present invention, a film pulling mechanism is provided directly above and to the side above the conveyor belt, and the film pulling mechanism includes a suction cup seat, a suction cup connected to the suction cup seat, and a film pulling cylinder for driving the suction cup seat to move.

[0013] As an improvement of the present invention, the pushing device includes a second crossbeam arranged parallel to and fixedly arranged relative to the first crossbeam, and two pushing units slidably connected to the second crossbeam. Each pushing unit includes a pushing slide block slidably connected horizontally to the second crossbeam, a pushing motor for driving the pushing slide block to slide, a cantilever block slidably connected horizontally to the pushing slide block and arranged perpendicularly to the second crossbeam, at least two vertically arranged support rods with their upper ends fixedly connected to the cantilever block, and a rotating cylinder respectively sleeved on each of the support rods. In the same pushing unit, each of the support rods is arranged sequentially along the length direction of the cantilever block.

[0014] As an improvement of the present invention, the cotton-continuing device includes a cotton-continuing frame, on which a cotton-receiving conveyor, a cotton-adhering conveyor, and a cotton-exiting conveyor are arranged in a straight line in sequence. The conveying surfaces of the cotton-receiving conveyor, the cotton-adhering conveyor, and the cotton-exiting conveyor are all arranged to gradually slope downward from the corresponding feed end to the corresponding discharge end. Above the conveying surface of the cotton-receiving conveyor, cotton-receiving partitions are arranged at equal intervals along the width direction of the cotton-receiving conveyor. Above the conveying surface of the cotton-adhering conveyor, a plurality of cotton-adhering partitions are arranged to connect or abut against each of the cotton-receiving partitions one-to-one. The distance between the ends of two adjacent cotton-adhering partitions away from the cotton-receiving conveyor is the same, and the distance between the ends of two adjacent cotton-adhering partitions away from the cotton-receiving conveyor is smaller than the distance between two adjacent cotton-receiving partitions.

[0015] As an improvement of the present invention, a sliding frame is slidably connected to the cotton feeding frame, and a sliding cylinder for driving the sliding frame to slide relative to the cotton feeding frame is provided on the cotton feeding frame. The sliding direction of the sliding frame is the same as the arrangement direction of the cotton receiving conveyor, the cotton approaching conveyor, and the cotton output conveyor. The cotton output conveyor is mounted on the sliding frame. A cutting mechanism located between the cotton output conveyor and the cotton approaching conveyor is provided on the sliding frame. The cutting mechanism includes a cutting slide block slidably connected to the sliding frame, a cutting cylinder for driving the cutting slide block to slide, a feed cylinder mounted on the cutting slide block, and a cutting knife detachably connected to the piston rod of the feed cylinder. The sliding direction of the cutting slide block is the same as the width direction of the cotton output conveyor.

[0016] As an improvement of the present invention, the fabric feeding station is provided with a replenishing conveying device and a layered feeding device connected to the discharge end of the replenishing conveying device. The layered feeding device includes a material distribution frame, a plurality of first conveying rollers that are parallel to each other and rotatably connected to the material distribution frame, a first conveying motor for driving the rotation of each first conveying roller, a lifting frame that is vertically slidably connected to the material distribution frame, and a lifting cylinder for driving the lifting frame to slide. Each first conveying roller is arranged in a horizontal straight line to form a first conveying section. A plurality of conveying supports located between two adjacent first conveying rollers are fixedly connected to the lifting frame. Each conveying support is equipped with a first belt conveying mechanism. The conveying surfaces of each first belt conveying mechanism are located on the same horizontal plane, and the conveying direction of each first belt conveying mechanism is the same as the length direction of the first conveying roller. A pusher and a support are arranged in parallel above the first conveying section. The length direction of the pusher and the support is the same as the conveying direction of the first conveying section. The lifting frame is provided with a pusher cylinder for driving the pusher to move horizontally along the length direction of the first conveying roller and a lifting handwheel or lifting motor for driving the support to move up and down.

[0017] By adopting the above solution, the present invention has the following beneficial effects:

[0018] 1. By setting up a material handling robot and an auxiliary robot on the same crossbeam, the material handling robot can transport all the materials at the incoming material station to the cotton replenishing device. Then, the auxiliary robot can transport the excess rock wool strips on the cotton replenishing device to the storage platform or replenish the rock wool strips from the cloth feeding station to the cotton replenishing device. This allows for the distribution of different rock wool strips according to actual production needs. The structure is relatively simple, the equipment cost is relatively low, and there is no need to set up a platform above the panel conveying device of the composite board production line, nor is there a need to install rock wool distribution devices or other structures on the platform. The equipment installation cycle is relatively short.

[0019] 2. The material-picking robot used in this invention uses a picking cylinder to drive the pins to insert into the rock wool strips to pick up the material. The picking cylinder drives the pins to retract, causing the pins to detach from the rock wool strips to unload the material. This can replace manual picking of rock wool strips, resulting in relatively high production efficiency. Since each pin in the pin unit is arranged parallel to the piston rods of the two picking cylinders, and the piston rods of the two picking cylinders are arranged in an inverted V-shape, there are at least two pins arranged in an inverted V-shape in the pin unit. Therefore, after each pin is inserted into the rock wool strip under the drive of the corresponding picking cylinder, the rock wool strip is not easy to slip off the pin, resulting in relatively good reliability. At the same time, since no baffle is needed for unloading, the structure is relatively simple and the cost is relatively low.

[0020] 3. The continuous cotton device used in this invention has inclined conveying surfaces for each conveying mechanism, so the rock wool strips do not need to change the conveying direction during the conveying process. The conveying speed is relatively consistent, and the rock wool strips arranged along the width of the conveying surface are less likely to be misaligned. The laying position is relatively accurate.

[0079] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0080] like Figures 1-10 As shown in the figure, this embodiment provides a rock wool strip feeding device for a composite board production line. The composite board production line can be a conventional production line, which has at least one panel conveying device 100. In this embodiment, two panel conveying devices 100 are used as an example for illustration. The two panel conveying devices are arranged in parallel with each other. One panel conveying device 100 is used to convey the upper panel of the composite board, and the other panel conveying device 100 is used to convey the lower panel of the composite board. During production, rock wool strips are laid on the lower panel, and then the upper panel is laminated onto the lower panel with rock wool strips laid on it using a flipping and bonding device. The action of laying rock wool strips on the lower panel can be completed using the rock wool strip feeding device provided in this embodiment. That is to say, the rock wool strip feeding device provided in this embodiment mainly works in conjunction with the panel conveying device 100 used to convey the lower panel.

[0081] The rock wool strip feeding equipment for a composite board production line provided in this embodiment includes a horizontally arranged first crossbeam 200, a picking robot 300 and an auxiliary robot 400 horizontally slidably connected to the first crossbeam 200, and a material receiving station, a storage platform 500, a cotton-replenishing device 600, and a replenishment station arranged along the length of the first crossbeam 200. The first crossbeam 200 is located above and perpendicular to the panel conveying device 100. The arrangement order of the material receiving station, storage platform 500, cotton-replenishing device 600, and replenishment station can be determined according to actual needs. In this embodiment, the material receiving station, storage platform 500, cotton-replenishing device 600, and replenishment station are arranged sequentially. Furthermore, the material receiving station, storage platform 500, and cotton-replenishing device 600 are all within the working range of the picking robot 300, and the storage platform 500, cotton-replenishing device 600, and replenishment station are all within the working range of the auxiliary robot 400.

[0082] The material receiving station can be a manual station, where neatly arranged rock wool strips are placed manually for the material handling robot 300 to pick up. To automate the material handling process, in this embodiment, the material receiving station is equipped with a feeding conveyor 710, an unpacking conveyor 720 connected to the discharge end of the feeding conveyor 710, an infeed conveyor 730 connected to the discharge end of the unpacking conveyor 720, a whole material conveyor 740 arranged side by side with the infeed conveyor 730, and a pushing device 750 for pushing the rock wool strips from the infeed conveyor 730 to the whole material conveyor 740. The unpacking conveyor 720 can also be used independently, meaning that this embodiment essentially also provides a rock wool unpacking conveyor. It should be noted that when the unpacking conveyor 720 is used independently, it can also include the feeding conveyor 710 and the infeed conveyor 730. In addition, the discharge end of the material conveying device 740, the inlet end of the storage platform 500 and the feed end of the cotton feeding device 600 are located on the same straight line so that the picking robot 300 and the auxiliary robot 400 can pick up or place the rock wool strips.

[0083] The feeding conveyor 710, the feeding conveyor 730, and the whole material conveyor 740 are all conventional roller conveyors or belt conveyors. Specifically, in this embodiment, the feeding conveyor 710 and the feeding conveyor 730 adopt conventional belt conveyors, and the whole material conveyor 740 adopts conventional roller conveyors. The conveying surface width of the whole material conveyor 740 is 3-4 times the conveying width of the feeding conveyor 710. Preferably, a plurality of limiting rollers 711 are rotatably connected to one side of the support of the feeding conveyor 710, arranged sequentially along the conveying direction of the feeding conveyor 710. In this way, during use, the worker can put the whole stack of rock wool strips into the conveying surface of the feeding conveyor 710 from the side of the feeding conveyor 710 without the limiting rollers 711, and let the rock wool strips abut against the limiting rollers 711 to limit their position on the conveying surface of the feeding conveyor 710, which is convenient for subsequent unpacking. It should be noted that the feeding conveyor 710 can also be equipped with limiting rollers 711 at a position relatively close to the feeding conveyor 710 on the side where the worker feeds the material, provided that it does not affect the worker's feeding operation. Both the feeding conveyor 730 and the bulk material conveyor 740 have multiple limiting rollers 711 rotatably connected to both sides of their supports, arranged sequentially along the corresponding conveying direction. This prevents the stacked rock wool strips from collapsing during conveying after unpacking. Furthermore, because the limiting rollers 711 are rotatably connected, the friction (rolling friction) between them and the rock wool strips is relatively small, making it difficult for the stacked rock wool strips to shift under frictional force. In addition, baffles 741 are fixedly connected to the supports at the discharge end of the feeding conveyor 730 and both ends of the bulk material conveyor 740 to prevent the rock wool strips from flowing out or falling from both ends of the bulk material conveyor 740.

[0084] The unpacking and conveying device 720 includes an unpacking frame 721, a drive roller 722 and a driven roller 723 arranged in parallel and rotatably connected to the unpacking frame 721, a conveying motor for driving the drive roller 722 to rotate, and a conveyor belt 724 wound between the drive roller 722 and the driven roller 723. The upper end face of the conveyor belt 724 forms a conveying surface. One end of the conveying surface of the conveyor belt 724 forms a feed end, and the other end forms a discharge end. The length of the conveying surface of the conveyor belt 724 needs to be determined according to the length of the rock wool strip, and is usually slightly smaller than the length of the rock wool strip to ensure that both ends of the rock wool strip can pass through the two ends of the conveying surface of the conveyor belt 724 respectively. A film cutting mechanism 725 is provided on the side of the driving roller 722 away from the driven roller 723 and on the side of the driven roller 723 away from the driving roller 722. The film cutting mechanism 725 includes a lifting seat 761 and a film cutting cylinder for driving the lifting seat 761 to move up and down. A knife holder 762 is fixedly connected to the lifting seat 761. The number of knife holders 762 needs to be determined according to the stacking method of the purchased rock wool strips. They are usually located between two adjacent rows of rock wool strips. For example, if the rock wool strips are stacked in two rows, only one knife holder 762 is needed. In this embodiment, the rock wool strips are stacked in four rows (i.e., four rows of rock wool strips are stacked separately and then close to each other and covered together with a protective film). In this embodiment, there are three knife holders 762. Each knife holder 762 is detachably connected to a cutter 763. In the conveying state, each cutter 763 vibrates below the conveying surface of the conveyor belt 724. During use, the entire stack of rock wool strips is fed into the conveying surface of the conveyor belt 724 via the feeding conveyor 710. When one end of the rock wool strip emerges from one end of the conveyor belt 724, and the other end has not yet entered the conveyor belt 724, the conveyor belt 724 stops conveying. The cutters 763 of each film-cutting mechanism 725 move upwards under the action of the corresponding film-cutting cylinder, cutting the protective film. It should be noted that it is also possible to retain only one film-cutting mechanism 725 and set the cutter 763 as a double-headed cutter, so that both ends of the entire stack of rock wool strips are cut once when conveyed to the position corresponding to the film-cutting mechanism 725.

[0085] Considering that the protective film covering some of the rock wool strips extends to the top and bottom sides of the entire stack, simply cutting the protective film at both ends of the stack cannot guarantee that the protective film will fall off, i.e., it is impossible to unpack. Therefore, in this embodiment, a film pulling mechanism 726 is provided directly above the conveyor belt 724 and on both sides above it. The film pulling mechanism 726 includes a suction cup seat 764, a suction cup 765 connected to the suction cup seat 764, and a film pulling cylinder 766 for driving the suction cup seat 764 to move. Specifically, the piston rod of the film pulling cylinder 766 is arranged vertically downwards in the film pulling mechanism 726 located directly above the conveyor belt 724, and the suction cup seat 764 is fixedly connected to the lower end of the piston rod of the film pulling cylinder 766. The film pulling mechanism is located on the side above the conveyor belt 725, and the piston rod of the film pulling cylinder 766 is arranged horizontally and faces the conveyor belt 724. The suction cup seat 764 is fixedly connected to the end of the piston rod of the film-pulling cylinder 766 facing the conveyor belt 724. In use, after the film-cutting mechanism 725 completes the cutting of the protective film, the suction cups 765 of each film-pulling mechanism 726, driven by the corresponding film-pulling cylinder 766, adsorb the protective film at the corresponding position. Then, each suction cup 765 retracts, tearing the protective film. Of course, the torn protective film needs to be removed promptly by manual means or a vacuum cleaner to avoid affecting subsequent production.

[0086] Preferably, the unpacking frame 721 has vertically arranged uprights fixedly connected to both sides of the feed end and the discharge end, and rollers 727 are fitted on the uprights to prevent the rock wool strips from tipping over during or after unpacking.

[0087] The pushing device 750 includes a second crossbeam 751 arranged parallel to and relatively fixed to the first crossbeam 200, and two pushing units slidably connected to the second crossbeam 751. The second crossbeam 751 spans above the feeding conveyor 730 and the material conveyor 740. Each pushing unit includes a pushing slide 752 slidably connected to the second crossbeam 751, a pushing motor 753 for driving the pushing slide 752 to slide, a cantilever 754 horizontally fixed to the pushing slide 752 and arranged perpendicular to the second crossbeam 751, at least two vertically arranged support rods 755 with their upper ends fixedly connected to the cantilever 754, and a rotating cylinder 756 respectively sleeved on each support rod 755. In the same pushing unit, each support rod 755 is arranged sequentially along the length direction of the corresponding cantilever 754. In use, when the unpacked rock wool strips are conveyed to the discharge end of the feeding conveyor 730, the rotating drum 756 of one of the pushing units rests against the side of the unpacked rock wool strip facing the material conveyor 740, while the rotating drum 756 of the other pushing unit rests against the side of the unpacked rock wool strip away from the material conveyor 740. Then, the two pushing units slide synchronously, pushing the rock wool strips onto the material conveyor 740. After pushing one stack of rock wool strips, the pushing unit on the side of the rock wool strip away from the material conveyor 740 resets, while the other pushing unit remains stationary. The next stack of rock wool strips is then conveyed... When the rock wool strips are delivered to the discharge end of the feeding conveyor 730, they are pushed onto the material conveyor 740 by the reset pushing unit. During this process, the next stack of rock wool strips will move to the position of abutting against the previous stack of rock wool strips. Then, the two pushing units slide synchronously, pushing the two stacks of rock wool strips to move synchronously, so that the next stack of rock wool strips moves onto the material conveyor 740. This process continues until the width of the material conveyor 740 is filled with rock wool strips. After that, the material conveyor 740 is used to transport all the rock wool strips together to the discharge end of the material conveyor 740, so that it is within the working range of the picking robot 300.

[0088] The material handling robot 300 can be an existing robot, such as the truss-type two-axis robot used in an automatic rock wool composite board laying system disclosed in Chinese invention patent CN216444339U. This embodiment uses a more reliable material handling robot 300, which can also be independently applied to other production scenarios requiring the handling of rock wool strips. In essence, this embodiment also provides a rock wool strip handling robot. Specifically, the material handling robot 300 provided in this embodiment includes a swab-taking mechanism 310 and an action component 320 for moving the swab-taking mechanism 310. The action component 320 can be a conventional component, such as a multi-joint robotic arm. In this embodiment, the action component 320 includes a base 321 horizontally slidably connected to the first crossbeam 200, a transverse motor 322 for driving the base 321 to slide, a lifting column 323 vertically slidably connected to the base 321, a lifting motor 324 for driving the lifting column 323 to slide up and down, and a support frame 325 installed at the lower end of the lifting column 323. Preferably, in this embodiment... In the example, the support frame 325 is rotatably connected to the lower end of the lifting column 323. The rotation axes of the two are arranged horizontally and parallel to the length direction of the support frame 325. The lifting column 323 is also equipped with a swing cylinder 326 for driving the support frame 325 to rotate relative to the lifting column 323. The cylinder body of the swing cylinder 326 is fixedly connected to the lifting column 323, and its piston rod is rotatably connected to the support frame 325. In this way, the extension and retraction of the piston rod of the swing cylinder 326 can drive the support frame 325 to swing relative to the lifting column 323, thereby picking up or placing rock wool strips placed on the inclined platform.

[0089] There are multiple tampon dispensing mechanisms 310, which are arranged in parallel along the length of the support frame 325 and slidably connected to the support frame 325 respectively. Each tampon dispensing mechanism 310 has an identical structure. Taking one of the tampon dispensing mechanisms 310 as an example, the tampon dispensing mechanism 310 includes a slide block 311 slidably connected to the support frame 325, a support rod 312 fixedly connected to the slide block 311, and pin units fixedly connected to both ends of the support rod 312. The pin units include pins fixedly connected to the ends of the support rod 312. The mounting base 313 on the corresponding support rod 312, the two cylinder bodies are respectively fixedly connected to the mounting base 313 to the material taking cylinder 314, and the needle seat 315 is respectively fixedly connected to the piston rod of each material taking cylinder 314. On the opposite side of the two needle seats 315 on the same needle unit, the needles 316 are respectively fixedly connected to the piston rod of the corresponding material taking cylinder 314. If the piston rods of the two material taking cylinders 314 on the same needle unit are arranged in an inverted V-shape, then the corresponding needles 316 are also arranged in an inverted V-shape. In use, the support frame 325 is moved above each rock wool strip located at the discharge end of the material conveying device 740, so that each strip-taking mechanism 310 is arranged in a one-to-one correspondence with each of the uppermost rock wool strips. Then, each picking cylinder 314 drives the corresponding insertion pin 316 to penetrate into the corresponding rock wool strip. Since some of the insertion pins 316 are arranged in an inverted V-shape, the rock wool strip is not easy to detach from the insertion pins 316, and the reliability is relatively good. After the rock wool strip is moved to the predetermined position, each insertion pin 316 is reset and pulled out from the corresponding rock wool strip, thus achieving unloading. Preferably, the insertion pin unit also includes a pressing seat 317 fixedly connected to the lower end of the mounting base 313. The pressing seat 317 has guide pin holes that respectively mate one-to-one with each insertion pin 316 on the same insertion pin unit to improve the operational stability of the insertion pin 316.

[0090] To facilitate simultaneous adjustment of the spacing between the picked-up rock wool strips during the feeding process, in this embodiment, the support frame 325 is also provided with an adjustment mechanism 330 for adjusting the spacing between the various rock wool picking mechanisms 310. The adjustment mechanism 330 includes connecting rods 331 rotatably connected to each support rod 312 and a telescopic cylinder 332 for driving one of the support rods 312 to slide. The spacing between each support rod 312 is always the same. One end of two adjacent connecting rods 331 is rotatably connected to each other, and the two connecting rods 331 form an angle of less than 180°. Each connecting rod 331 and the support rod 312 rotatably connected to it are not perpendicular (i.e., they are never perpendicular). The rotatable connection point between each connecting rod 331 is the same as the spacing between the two support rods 312 closest to that rotatable connection point. In this way, when the telescopic cylinder 332 drives one of the support rods 312, the other support rods 312 can be pushed to slide synchronously through each connecting rod 331, ensuring that the spacing between each support rod 312 is always the same.

[0091] Similar to the material handling robot 300, the auxiliary robot 400 also includes a cotton strip picking mechanism 310 and an action component 320 for moving the cotton strip picking mechanism 310. The difference is that the auxiliary robot 400 only has one cotton strip picking mechanism 310. The action component 320 used by the auxiliary robot 400 can be exactly the same as the action component 320 used by the material handling robot 300. Considering that the auxiliary robot 400 only needs to operate on one rock wool strip, the action component 320 used by the auxiliary robot 400 in this embodiment does not include a support frame 325 and a swing cylinder 326. Instead, the support rod 312 of the cotton strip picking mechanism 310 is directly fixedly connected to the lower end of the lifting column 323, and a cylinder or push rod motor is used instead of the lifting motor 324 to drive the lifting column 323 to move up and down.

[0092] The storage platform 500 can be a conventional platform. In this embodiment, the storage platform 500 is based on a conventional platform, and multiple storage partitions 510 are arranged perpendicularly to the first crossbeam 200 on the platform. A storage space for placing rock wool strips is formed between two adjacent storage partitions 510 so as to accurately pick up the rock wool strips on the storage platform 500.

[0093] The cotton-refilling device 600 can be an existing device, such as the cotton-refilling device disclosed in Chinese Invention Patent Publication No. CN218140492U. This embodiment employs a novel cotton-refilling device, essentially providing a cotton-refilling device for rock wool composite panels. Specifically, the cotton-refilling device 600 provided in this embodiment includes a cotton-refilling frame 610. The cotton-refilling frame 610 includes a frame 611 spanning a panel conveying device 100 for conveying the lower panel and a mounting frame 612 located directly above the panel conveying device 100 and inclined relative to the horizontal plane. A lifting seat 613 is vertically slidably connected to the frame 611, and an adjustment mechanism for controlling the sliding position of the lifting seat 613 is provided on the frame 611. This adjustment mechanism can be a conventional mechanism, such as an adjusting screw screw screwed to the frame 611 and rotatably connected to the lifting seat 613. The upper end of the mounting frame 612 is rotatably connected to the frame 611, and the lower end is rotatably connected to the lifting seat 613. This facilitates adjusting the horizontal position of the lower end of the mounting frame 613 according to the thickness of the composite board. The mounting frame 612 of the cotton feeding machine frame 610 is provided with a cotton receiving conveyor 620, a cotton contact conveyor 630, and a cotton output conveyor 640 connected in a straight line. The cotton receiving conveyor 620, the cotton contact conveyor 630, and / or the cotton output conveyor 640 are conventional belt conveyor mechanisms. The conveying surfaces of the cotton receiving conveyor 620, the cotton contact conveyor 630, and the cotton output conveyor 640 are all arranged to gradually slope downward from the corresponding feed end to the corresponding output end. That is, the feed end of the cotton receiving conveyor 620 is located at the upper end of the mounting frame 612, and the output end of the cotton output conveyor 640 is located at the lower end of the mounting frame 612.

[0094] Above the conveying surface of the cotton receiving conveyor 620, multiple cotton receiving baffles 621 are arranged at equal intervals along the width direction of the cotton receiving conveyor 620. Above the conveying surface of the cotton-adhering conveyor 630, multiple cotton-adhering baffles 631 are arranged to connect or abut against each cotton receiving baffle 621 one-to-one. Neither the cotton receiving baffles 621 nor the cotton-adhering baffles 631 contact the corresponding conveying surface. Thus, a guide channel for guiding the rock wool strips can be formed between adjacent cotton receiving baffles 621 and between adjacent cotton-adhering baffles 631. The guide channels on the two conveying mechanisms are connected one-to-one to ensure accurate conveying position. Furthermore, the distance between the ends of adjacent cotton-adhering baffles 631 away from the cotton receiving conveyor 620 is the same, and the distance between the ends of adjacent cotton-adhering baffles 631 away from the cotton receiving conveyor 621 is smaller than the distance between adjacent cotton receiving baffles 621. This allows adjacent rock wool strips to move closer together during conveying.

[0095] Preferably, in this embodiment, a sliding frame 614 is slidably connected to the lower end of the mounting frame 612 of the cotton feeding machine frame 610, and a sliding cylinder 615 for driving the sliding frame 614 to slide relative to the cotton feeding machine frame 610 is provided on the mounting frame 612 of the cotton feeding machine frame 610. The sliding direction of the sliding frame 614 is the same as the arrangement direction of the cotton conveying mechanism 620, the cotton contact conveying mechanism 630, and the cotton output conveying mechanism 640. The cotton output conveying mechanism 640 is indirectly mounted on the mounting frame 612 by being mounted on the sliding frame 614, and a cutting mechanism 6 is provided on the sliding frame 614 between the cotton output conveying mechanism 640 and the cotton contact conveying mechanism 630. 50. The cutting mechanism 650 includes a cutting slide 651 slidably connected to the sliding frame 614, a cutting cylinder 652 for driving the cutting slide 651 to slide, a feed cylinder 653 mounted on the cutting slide 651, and a piston rod cutting knife detachably connected to the feed cylinder 653. The cutting cylinder 652 is a rodless cylinder. The feed cylinder 653 is located below the conveying surface of the cotton conveying mechanism 640 and its piston rod faces the cotton conveying mechanism 640. During normal conveying, the cutting knife is located below the conveying surface of the cotton conveying mechanism 640. When cutting is required, the cutting knife extends upward under the drive of the feed cylinder 653 for cutting. The sliding direction of the cutting slide 651 is the same as the width direction of the cotton conveying mechanism 640. During cutting, the cotton conveying mechanism 620 and the cotton-adjacent conveying mechanism 630 do not stop conveying. The sliding frame 614 slides away from the cotton-adjacent conveying mechanism 630, and the sliding speed is the same as the conveying speed of the cotton conveying mechanism 620 and the cotton-adjacent conveying mechanism 630. The cutting cylinder 652 drives the cutting knife 653 to move from one side of the sliding frame 614 to the other side, realizing simultaneous conveying and cutting, which has relatively high production efficiency.

[0096] A pressing assembly 660 is provided at the end of the cotton conveying mechanism 640 away from the cotton conveying mechanism 630. The pressing assembly 660 includes two pressing cylinders 661 respectively fixedly connected to the sliding frame 614, and pressing rollers 662 rotatably connected to the piston rods of the two pressing cylinders 661 at both ends. The pistons of the pressing cylinders 661 are arranged downwards, and the pressing rollers 662 are arranged horizontally and perpendicular to the conveying direction of the cotton conveying mechanism 640. In addition, a pressing assembly 660 is also provided above the conveying surface of the cotton conveying mechanism 640 to prevent the position of each rock wool strip from changing during the discharge process.

[0097] Preferably, the sliding frame 614 is provided with a guide assembly 670 at a position corresponding to the discharge end of the cotton conveying mechanism 640. The guide assembly 670 includes two guide frames 671 located on both sides of the discharge end of the cotton conveying mechanism 640, and a guide motor 672 for driving the two guide frames 671 to move towards or away from each other. The specific transmission connection structure between the guide motor 672 and the two guide frames 671 can be a conventional structure. For example, a double-ended lead screw is rotatably connected to the sliding frame 614, and the output shaft of the guide motor 672 is connected to the double-ended lead screw through a coupling. The double-ended lead screw has a first lead screw section and a second lead screw section with opposite helical directions. A first lead screw nut is sleeved on the first lead screw section and fixedly connected to one of the guide frames 671, and a second lead screw nut is sleeved on the second lead screw section and fixedly connected to the other guide frame 671. At least two guide wheels 673 are rotatably connected to the guide frame 671, arranged sequentially along the conveying direction of the cotton discharge conveying mechanism 640, which helps to further improve the accuracy of the discharge position.

[0098] The material receiving station can be a manual station, where neatly arranged rock wool strips are placed manually for the auxiliary robotic arm 400 to grip. To automate the material placement, in this embodiment, the material feeding station is equipped with a replenishment conveyor 810 and a layered feeding device 820 connected to the discharge end of the replenishment conveyor 810. The structure of the material feeding conveyor 810 is the same as that of the loading conveyor 710, and will not be described in detail here. If necessary, an unpacking conveyor 720 can be installed between the replenishment conveyor 810 and the layered feeding device 820. Considering that the replenishment station requires relatively little material, the unpacking conveyor 720 is not installed in this embodiment.

[0099] The layered feeding device 820 includes a feeding frame 822, multiple parallel first conveyor rollers 821 rotatably connected to the feeding frame 822, a first conveyor motor for driving the rotation of each first conveyor roller 821, a lifting frame 823 vertically slidably connected to the feeding frame 822, and a lifting cylinder 824 for driving the lifting frame 823 to slide. The specific transmission connection structure between the first conveyor motor and each first conveyor roller 821 is the same as that between the conveyor rollers and the conveyor motor in a conventional roller conveyor, for example, using a chain assembly for transmission connection, which will not be detailed here. The first conveyor rollers 821 are arranged horizontally in a straight line to form a first conveying section. One end of the first conveying section serves as the input end of the layered feeding device 820, connecting to the output section of the supplementary conveying device 810, and the first conveying section and the supplementary conveying device 810 are located on the same straight line.

[0100] Multiple conveyor supports 829 are fixedly connected to the lifting frame 823, each located between two adjacent first conveyor rollers 821. The conveyor supports 829 are arranged parallel to each other. In this embodiment, a conveyor support 829 is provided between each pair of adjacent first conveyor rollers 821, and each conveyor support 829 is equipped with a first belt conveyor mechanism 826, which are also arranged parallel to each other. The first belt conveyor mechanism 826 and all other belt conveyor mechanisms mentioned below are conventional structures and can be purchased directly from the market. They include two driven pulleys arranged parallel to each other and on the same horizontal plane, a driving pulley located between the two driven pulleys and at a horizontal position lower than the horizontal position of the two driven pulleys, a synchronous belt wound between the driving pulley and each driven pulley, and a drive motor for driving the driving pulley to rotate. The synchronous belt is located on the conveying surface of the segmented belt conveyor mechanism between the two driven pulleys. It should be noted that each of the first belt conveyor mechanisms 826 can share a single drive motor (i.e., each drive pulley is mounted on the same transmission shaft, and then the transmission shaft is connected to the drive motor), or each of the first belt conveyor mechanisms 826 can be equipped with an independent drive motor.

[0101] The conveying surfaces of each first belt conveyor mechanism 826 are located on the same horizontal plane, and the conveying direction of each first belt conveyor mechanism 826 is the same as the length direction of the first conveyor roller 821. In use, each first belt conveyor mechanism 826 can be moved under the drive of the lifting frame 823 according to actual needs, so that its conveying surface is higher or lower than the horizontal position of the first conveying section.

[0102] Above the first conveying section, a pusher 840 and a support 850 are arranged in parallel. The pusher 840 and the support 850 are located above the first belt conveyor mechanism 826, and the length direction of the pusher 840 and the support 850 is the same as the conveying direction of the first conveying section. Meanwhile, the lifting frame 823 is equipped with a pusher cylinder 827 for driving the pusher 840 to move horizontally along the length direction of the first conveying roller 821, and a lifting handwheel 828 or a lifting motor for driving the support 850 to move up and down. In this embodiment, the lifting handwheel 828 is used as an example for explanation. Preferably, the pusher 840 includes a crossbeam 841 and a plurality of vertically arranged push rollers 842 rotatably connected to the crossbeam 841. Each push roller 842 is arranged sequentially along the length of the crossbeam 841. The piston rod of the pusher cylinder 827 is fixedly connected to the crossbeam 841. The support frame 850 includes a support beam 851 and a plurality of vertically arranged abutment rollers 852 rotatably connected to the support beam 851. Each abutment roller 852 is arranged sequentially along the length of the support beam 851. Support seats 853 are fixedly connected to both ends of the support beam 851. The two support seats 853 have identical structures. Taking one as an example, a vertically arranged guide rod 854 is slidably connected to the support seat 853. The lower end of the guide rod 854 is fixedly connected to the lifting frame 823, and the upper end is fixedly connected to a support plate 855. A rotating guide rod 854 is mounted on the support plate 855. A vertically arranged lead screw 856 is connected to the moving part. A lead screw nut (not shown in the figure) is fitted on the lead screw 856 and fixedly connected to the support base 853. A lifting handwheel 828 or a lifting motor is connected to the lead screw 826. The specific transmission connection structure can be a conventional structure, such as a direct connection or a connection through a coupling. In this way, the lifting handwheel 828 or the lifting motor can drive the lead screw 826 to rotate, thereby driving the two supports 851 to move up and down. Before use, the height position of the two supports 851 is adjusted by the lifting handwheel 828 or the lifting motor so that after the conveying surface of the first belt conveyor mechanism 826 rises to the limit position, the distance between the conveying surface and the two supports 851 is greater than the thickness of one rock wool strip and less than the thickness of two rock wool strips, so as to ensure that only one rock wool strip is conveyed at a time. Since the abutment roller 852 and the push roller 842 are rotatably connected, the rock wool strip is not easily damaged.

[0103] In use, the stack of rock wool strips is placed on the feeding conveyor 710 manually or by forklift. Driven by the feeding conveyor 710, the stack of rock wool strips is fed into the unpacking conveyor 720 for unpacking and removal of the protective film. The unpacked rock wool strips are then driven by the unpacking conveyor 720 into the feeding conveyor 730 and conveyed to the discharge end of the feeding conveyor 730. Then, the pushing device 750 pushes them onto the material conveyor 740. After the material conveyor 740 collects the predetermined stack of rock wool strips, it conveys these rock wool strips together to the discharge end of the material conveyor 740. Then, the picking robot 300 uses the picking robot 300 to clamp the top layer of rock wool strips at the discharge end of the material conveyor 740 onto the conveying surface of the receiving conveyor 620. Of course, the number of rock wool strips at the discharge end of the material conveyor 740 and located on the same layer is the same as the number of picking mechanisms 310 of the picking robot 300. After the picking robot 300 picks up the rock wool strips but before placing them, the oscillating cylinder 326 drives the support frame 325 to swing, so that each rock wool strip is arranged parallel to the conveying surface of the receiving conveyor 620. At the same time, the adjusting mechanism 330 adjusts the spacing between each rock wool strip to ensure that they can be placed one-to-one into the guide channel of the interface conveying device 620. After that, the picking robot 300 resets. If the composite board production process requires a large gap between each rock wool strip or between some rock wool strips (usually the gap is the width of one rock wool strip or the width of a rock wool strip), then the rock wool strips will be placed in a different position. If the width is an integer multiple of the rock wool strip, the auxiliary robot 400 will pick up the corresponding rock wool strip from the receiving conveyor 620 and place it on the storage platform 500. Then, the rock wool strip is conveyed to the output conveyor 640 in sequence through the receiving conveyor 620 and the receiving conveyor 630. During this process, the rock wool strip is cut according to the production process requirements by the cooperation of the sliding frame 614 and the cutting mechanism 650. The cut rock wool strip is laid on the panel of the panel conveyor 100 under the conveying of the output conveyor 640, completing the feeding action of the entire rock wool strip. Furthermore, without affecting the working sequence of the material handling robot 300 and the action of the auxiliary robot 400 picking up rock wool strips from the receiving conveyor 620 and placing them on the storage platform 500, the auxiliary robot 400 can be used to pick up the rock wool strips located on each of the first belt conveyor mechanisms 826 and place them on the storage platform 500. When the number of rock wool strips on the storage platform 500 is the same as the number of the strip picking mechanism 310 of the material handling robot 300, the material handling robot 300 does not pick up the rock wool strips located at the discharge end of the material conveyor 740, but instead picks up all the rock wool strips located on the material platform 500 and places them on the conveying surface of the receiving conveyor 620.
