Towel discharging and stacking machine with pushing function

Abstract

This utility model relates to the field of material unloading and palletizing machine technology, and discloses a towel unloading and palletizing machine with a pushing function. It includes a support frame, with a placement plate for unloading fixedly connected to the lower part of the frame. A loading component for stacking and pushing materials is installed inside the frame. After the loading plate is lowered to the placement plate position by a lifting cylinder, a pushing cylinder drives the pushing plate to smoothly push the entire stack of towels onto the placement plate. The loading plate can be reset for the next round of stacking. Simultaneously, the operator can process finished products, eliminating the production gap caused by waiting for manual material removal in traditional equipment. During the pushing process, a spur gear meshes with a rack and pinion to drive a worm gear transmission, causing the protective plate to automatically rotate to a horizontal state, forming a double-sided constraint with the pushing plate. This provides timely support and protection when towels shift, effectively preventing the towel stack from loosening and collapsing, significantly improving conveying stability and operational continuity.

Description

Technical Field

[0001] This utility model relates to the field of material feeding and palletizing machine technology, specifically to a towel feeding and palletizing machine with a pushing function. Background Technology

[0002] As a key piece of equipment in the downstream process of the towel production line, the unloading and palletizing machine realizes intelligent stacking and transfer of textiles through an automated mechanical structure. The equipment uses photoelectric sensing technology to accurately count the folded towels on the conveyor belt. When the preset number is reached, the servo-driven lifting platform stacks the towels into neat stacks of uniform height, and finally smoothly transports the towel stacks to the carrier at the packaging station.

[0003] Existing towel palletizing machines require manual removal of the finished towel stacks from their platforms after completing a predetermined number of towel stacks. This manual intervention results in the entire palletizing equipment being in a passive, waiting, and downtime state. This intermittent production interruption not only leads to low equipment utilization but also creates bottlenecks in continuous production processes, preventing smooth transitions between processes and impacting production efficiency. Therefore, those skilled in the art provide a towel palletizing machine with a pushing function to solve the problems mentioned in the background art. Summary of the Invention

[0004] The purpose of this utility model is to provide a towel feeding and palletizing machine with a pushing function, so as to solve the problems mentioned in the background art above.

[0006] As a preferred embodiment of the above technical solution, the loading assembly includes a pushing and moving large air cylinder, front and rear sliding guide rails, and a lifting air cylinder. The pushing and moving large air cylinder is fixedly installed on the lower part of the inner wall of the mounting frame. Two front and rear sliding guide rails are provided, and the two front and rear sliding guide rails are fixedly connected to the lower end face of the placement plate, and the two front and rear sliding guide rails are symmetrically arranged. The lifting air cylinder is fixedly installed on the upper end of the mounting frame, and the loading plate is fixedly installed on the output end of the lifting air cylinder. A moving plate is slidably connected between the two front and rear sliding guide rails. The moving plate is installed on the output end of the pushing and moving large air cylinder, and two symmetrically arranged pushing plates are fixedly connected to the upper end of the moving plate.

[0007] As a preferred embodiment of the above technical solution, the carrying plate has two guide openings, and the two pusher plates are slidably disposed in the two guide openings respectively. Each of the two pusher plates has a lifting groove on the side near the placement plate, and each of the two lifting grooves is slidably connected to an upper and lower sliding guide rail. The side of each of the two upper and lower sliding guide rails away from the lifting cylinder is fixedly connected to a large pusher plate. Guide grooves are provided on both sides of the carrying plate, and guide rollers are rotatably connected to both sides of the lower end of the large pusher plate. The two guide rollers are respectively disposed in the two guide grooves.

[0008] As a preferred embodiment of the above technical solution, the protective assembly includes a transmission rod, a connecting rod, and a rack. The transmission rod is rotatably sleeved in the middle of the side wall of the pusher plate. The connecting rod is fixedly connected to one side of the pusher plate. The rack is fixedly connected to the edge of the side wall of the carrying plate. Protective plates are fixedly connected to both ends of the transmission rod. A worm gear is fixedly connected to the side of one of the protective plates away from the pusher plate. A worm is rotatably connected to the lower end of the connecting rod. The worm gear and the worm mesh with each other. A spur gear is fixedly connected to the lower end of the worm. The spur gear and the rack mesh with each other.

[0009] As a preferred embodiment of the above technical solution, the transfer assembly includes casters and pneumatic locking devices, with four casters and four pneumatic locking devices provided. The four casters are fixedly installed at the four corners of the lower end of the mounting frame, and the four pneumatic locking devices are fixedly connected to the lower end of the mounting frame.

[0010] As a preferred embodiment of the above technical solution, two pusher cylinders are fixedly connected to the side of the two pusher plates away from the pusher plate, and a guide shaft is fixedly connected to the middle of the side of the two pusher plates away from the pusher plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By stacking towels on the carrier plate, after stacking, the lifting cylinder drives the carrier plate to the lowest point. At this time, the carrier plate is facing the placement plate. Then, the pushing cylinder starts to work, which drives the pushing plate to slide in the guide port. The pushing plate smoothly pushes the entire stack of towels to the placement plate, so that the carrier plate can be reset immediately after pushing to enter the next round of stacking operation. Meanwhile, the operator can process the finished products that have been transferred to the placement plate at the same time, eliminating the production gap caused by waiting for manual material handling in traditional equipment, and keeping the equipment in a state of high efficiency at all times.

[0013] 2. During the movement of the pusher plate, the spur gear will contact the rack. With the cooperation of the worm gear and worm, the transmission rod will rotate, which will cause the protective plate to rotate to a horizontal state. The pusher plate, together with the double protective plates, will constrain the entire stack of towels. The protective plates are located at the center of both sides of the stack of towels. When the pusher plate pushes the towels, if the towels are slightly offset, the protective plates can support the towels, effectively preventing the towels from loosening or collapsing during the pusher process, and improving the overall stability of the entire stack of towels during the conveying process.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a towel feeding and palletizing machine with a pushing function, including a mounting frame 1 for support, a placement plate 2 for feeding is fixedly connected to the lower part of the mounting frame 1, a loading component 3 for stacking and pushing materials is installed inside the mounting frame 1, a protective component 4 for preventing materials from collapsing is installed on one side of the loading component 3, and a transfer component 5 for moving the mounting frame 1 is installed at the lower end of the mounting frame 1.

[0021] As one implementation method in this embodiment, please refer to Figure 1 - Figure 3 As shown, the loading assembly 3 includes a pushing and moving air cylinder 301, front and rear sliding guide rails 302, and a lifting cylinder 303. The pushing and moving air cylinder 301 is fixedly installed on the lower part of the inner wall of the mounting frame 1. There are two front and rear sliding guide rails 302, which are fixedly connected to the lower end face of the placement plate 2 and are symmetrically arranged. The lifting cylinder 303 is fixedly installed on the upper end of the mounting frame 1. The output end of the lifting cylinder 303 is fixedly installed with a loading plate 304. A moving plate 305 is slidably connected between the two front and rear sliding guide rails 302. The moving plate 305 is installed on the output end of the pushing and moving air cylinder 301. Two symmetrically arranged pushing plates 306 are fixedly connected to the upper end of the moving plate 305.

[0022] Two guide openings 307 are provided in the loading plate 304. Two pusher plates 306 are slidably disposed in the two guide openings 307 respectively. A lifting groove 308 is provided on the side of the two pusher plates 306 near the placement plate 2. A vertical sliding guide rail 309 is slidably connected in the two lifting grooves 308. A pusher plate 310 is fixedly connected on the side of the two vertical sliding guide rails 309 away from the lifting cylinder 303. Guide grooves 311 are provided on both sides of the loading plate 304. Guide rollers 312 are rotatably connected on both sides of the lower end of the pusher plate 310. The two guide rollers 312 are disposed in the two guide grooves 311 respectively.

[0023] Furthermore, by stacking towels on top of the carrier plate 304, after stacking, the output end of the lifting cylinder 303 pushes the carrier plate 304 down. Since the guide roller 312 is located inside the guide groove 311, the guide roller 312 can roll inside the guide groove 311. When the carrier plate 304 descends, under the limitation of the guide roller 312 and the guide groove 311, the up and down sliding guide rail 309 on the pusher plate 310 will slide in the lifting groove 308, thereby driving the pusher plate 310 down. When the carrier plate 304 descends to the lowest point, the carrier plate 304... Facing the placement plate 2, the large pusher cylinder 301 starts working, driving the moving plate 305 to move within the front and rear sliding guide rails 302. This allows the pusher plate 306 to slide within the guide opening 307 on the carrier plate 304. The pusher plate 310 then smoothly pushes the entire stack of towels onto the placement plate 2, allowing the carrier plate 304 to immediately reset after pushing the towels and enter the next round of stacking operations. Meanwhile, the operator can simultaneously process the finished products that have been transferred to the placement plate 2, eliminating the production gaps caused by waiting for manual material handling in traditional equipment and ensuring that the equipment is always in a highly efficient operating state.

[0024] As one implementation method in this embodiment, please refer to Figure 1 , Figure 2and Figure 4 As shown, the protective component 4 includes a transmission rod 401, a connecting rod 402, and a rack 403. The transmission rod 401 is rotatably sleeved in the middle of the side wall of the pusher plate 310. The connecting rod 402 is fixedly connected to one side of the pusher plate 310. The rack 403 is fixedly connected to the edge of the side wall of the carrying plate 304. Protective plates 404 are fixedly connected to both ends of the transmission rod 401. A worm gear 405 is fixedly connected to the side of one of the protective plates 404 away from the pusher plate 310. A worm 406 is rotatably connected to the lower end of the connecting rod 402. The worm gear 405 and the worm 406 mesh with each other. A spur gear 407 is fixedly connected to the lower end of the worm 406. The spur gear 407 and the rack 403 mesh with each other.

[0025] Furthermore, during the pushing process of the large pushing plate 310, the spur gear 407 contacts the rack 403, which drives the worm gear 406 to rotate, and the worm wheel 405 to rotate, thereby driving the protective plate 404 to rotate to a horizontal state. When the spur gear 407 disengages from the rack 403, the protective plate 404 is fixed at a specified angle due to the mechanical locking of the worm gear 406 and the worm wheel 405. The large pushing plate 310, together with the double protective plates 404, constrains the entire stack of towels. The protective plates 404 are located at the center of both sides of the stack of towels. When the large pushing plate 310 pushes the towels, if the towels slightly shift, the protective plates 404 can provide some support for the towels, effectively preventing the towels from loosening or collapsing during the pushing process, and improving the overall stability of the entire stack of towels during the conveying process. When the large pushing plate 310 resets, the spur gear 407 rotates in the opposite direction, which resets the protective plate 404, preventing the protective plate 404 from affecting the feeding operation.

[0026] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, the transfer assembly 5 includes casters 501 and pneumatic locking devices 502. There are four casters 501 and four pneumatic locking devices 502. The four casters 501 are fixedly installed at the four corners of the lower end of the mounting frame 1, and the four pneumatic locking devices 502 are fixedly connected to the lower end of the mounting frame 1.

[0027] Furthermore, the universal wheel 501 can move the device, allowing it to be moved to a designated position as needed. The pneumatic locking device 502 is existing technology, mainly consisting of a pneumatic piston, a locking block, and a return spring. The piston is driven by air pressure to move, pushing the locking block to contact the ground. The friction between the locking block and the ground restricts the rotation and direction of the universal wheel 501, thereby preventing the device from moving. This will not be elaborated further here.

[0028] As one implementation method in this embodiment, please refer to Figure 1 - Figure 2As shown, two pusher cylinders 6 are fixedly connected to the side of the two pusher plates 306 away from the pusher plate 310, and guide shafts 7 are fixedly connected to the middle of the side of the two pusher plates 306 away from the pusher plate 310.

[0029] Furthermore, the pusher cylinder 6 can assist in moving the pusher plate 306. When the pusher moving cylinder 301 starts working, the pusher cylinder 6 works synchronously. The output end of the pusher cylinder 6 will abut against the inner wall of the mounting frame 1, thereby applying a pushing force to the pusher plate 306. The multiple pusher cylinders 6 arranged in an upper and lower array work synchronously with the pusher moving cylinder 301, which can disperse the initial pushing force into a multi-point uniform load, avoiding static friction sudden impact caused by single-point concentrated force. At the same time, the acceleration sudden change is reduced through coordinated motion control, and the multi-level support structure enhances the anti-overturning ability, making the pusher plate 306 move and push the material more smoothly and stably, effectively preventing the stack from collapsing due to excessive instantaneous pushing force.

[0030] Working principle: By stacking towels on top of the carrier plate 304, after stacking, the output end of the lifting cylinder 303 pushes the carrier plate 304 down. Since the guide roller 312 is set inside the guide groove 311, when the carrier plate 304 descends, under the limit of the guide roller 312 and the guide groove 311, the upper and lower sliding guide rails 309 on the pusher plate 310 will slide in the lifting groove 308, thereby driving the pusher plate 310 down. When the carrier plate 304 descends to the lowest point, the carrier plate 304 is directly facing the placement plate 2. Then the pusher moving cylinder 301 starts to work, driving the moving plate 305 to move in the front and rear sliding guide rails 302, so that the pusher plate 306 can slide in the guide opening 307 on the carrier plate 304. The pusher plate 310 can then smoothly push the entire stack of towels to the top of the placement plate 2, so that the carrier plate 304 can immediately reset after completing the push and enter the next round of stacking operation, while the operator can handle the operation simultaneously. The finished products transferred to placement plate 2 eliminate the production gaps caused by waiting for manual material handling in traditional equipment, ensuring that the equipment is always in a highly efficient operating state. During the pushing process of the large pushing plate 310, the spur gear 407 will contact the rack 403. The spur gear 407 drives the worm gear 406 to rotate, and the worm wheel 405 will rotate, thereby driving the protective plate 404 to rotate to a horizontal state. When the spur gear 407 disengages from the rack 403, the protective plate 404 is fixed at a specified angle due to the mechanical locking of the worm gear 406 and the worm wheel 405. The large pushing plate 310, together with the double protective plates 404, constrains the entire stack of towels. The protective plates 404 are located at the center of both sides of the stack of towels. When the large pushing plate 310 pushes the towels, if the towels are slightly offset, the protective plates 404 can provide some support for the towels, effectively preventing the towels from loosening or collapsing during the pushing process, and improving the overall stability of the entire stack of towels during the conveying process.

[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
