Description

Technical Field

[0001] This invention relates to the field of paper roll ejector pressure prevention technology, and more particularly to a paper roll ejector pressure prevention device for partitioning paper rolls in an automated warehouse. Background Technology

[0002] The paper kicker is suitable for use in the automatic paper roll conveyor line of the finishing section in a papermaking workshop. When the paper kicker kicks the paper, the piston rod of the cylinder acting on the short arm of the rocker arm is pulled back downwards, the long arm of the rocker arm swings forward, and drives the kicking roller to kick out, thus kicking the paper roll out of the V-type chain conveyor. After the paper roll is in place, the piston rod of the cylinder acting on the short arm of the rocker arm pushes upwards, and the kicking roller returns to its original position. During the conveying process of the paper roll on the chain conveyor, if the air supply pipe suddenly falls off or the air compressor station trips, causing the air supply to be interrupted, the cylinder of the paper kicker will lose pressure. Under its own weight, the paper kicker will pop out, and the paper roll kicked off the chain conveyor will fall and damage the equipment.

[0003] Chinese Patent Publication No. CN213894237U, published on August 6, 2021, discloses a paper roll partitioning anti-pressure loss device for a three-dimensional warehouse, including a base, a frame, an air control box, and a cylinder. The frame is fixed on the top of the base, and the cylinder is fixedly installed on the back of the frame. The air control box is fixedly installed on the outer wall of one side of the frame. A T-type three-way quick connector is fixedly installed at the front end of the one-way throttle valve in the rod chamber of the cylinder. An air control pilot valve is fixedly installed on the inner and outer thread transition joint of the cylinder, and the air orifice pilot valve is connected to a quick exhaust valve through a compression fitting outer thread straight connector.

[0004] Existing pressure-loss prevention devices for paper roll partitioning in automated warehouses, such as the aforementioned ones, aim to address sudden pressure loss in the push cylinder using electrical components like pneumatic pilot valves and throttling silencers. However, in practice, these components themselves require power, meaning they inherently possess certain uncontrollable factors. This prevents the pressure-loss prevention device from reliably providing the necessary protection. Therefore, there is an urgent need to develop a corresponding pressure-loss prevention device for paper roll partitioning in automated warehouses to address these issues. Summary of the Invention

[0005] The purpose of this invention is to provide a pressure-prevention device for paper roll partitioning in a three-dimensional warehouse, in order to solve the above-mentioned problems.

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

[0007] A pressure-loss prevention device for a paper roll partitioning system in an automated warehouse includes a frame, a swing arm, and a push cylinder. A connecting compartment is fixedly installed on the outer wall of the vertical end of the frame. A shaft is rotatably connected to the inner wall of the connecting compartment. A take-up drum and a toothed disc are fixedly installed on the outer wall of the shaft. A tension spring is fixedly installed between the outer wall of the shaft and the inner wall of the connecting compartment. A connecting strip is wound around the outer wall of the take-up drum. The open end of the connecting strip is fixedly connected to the outer wall of the swing arm. A fixed seat is fixedly installed on the inner wall of the bottom of the connecting compartment. A limit frame is rotatably connected to the outer wall of the fixed seat. The outer wall of the limit frame is provided with a toothed edge. A linkage component for triggering the limit frame is provided between the fixed seat and the toothed disc.

[0008] Preferably, the linkage component includes a rocker arm and a slide bar. The rocker arm is rotatably connected to the rear end face of the gear plate via an elastic rotating shaft. The slide bar is slidably connected to the fixed seat, and the front end face of the slide bar is provided with a pushing part for axially pushing the limit frame.

[0009] Preferably, a limiting rod is provided on the outer side of the rocker arm, and the limiting rod is integrally formed with the gear plate.

[0010] Preferably, an arc-shaped rod is fixedly installed on the inner wall of the fixed base, and a sliding sleeve that is fixedly connected to the sliding rod is slidably connected to the outer wall of the arc-shaped rod, and a spring is fixedly installed between the sliding sleeve and the inner wall of the fixed base.

[0011] Preferably, the pushing part includes a protruding rod that is fixedly connected to the slide rod, and the protruding rod is slidably connected to the inner wall of the limiting frame through a sliding groove.

[0012] Preferably, an audible and visual alarm is fixedly installed on the top of the connecting compartment, a mounting plate is fixedly installed on the inner wall of the fixed base, and a moving contact and a stationary contact are respectively provided on the outer wall of the sliding sleeve and the mounting plate.

[0013] Preferably, the arc-shaped end of the connecting compartment is connected to a cover, and the outer wall of the cover is integrally formed with a strip, which is fixedly connected to the connecting compartment by a locking rod.

[0014] Preferably, a base frame is fixedly installed at the bottom of the connecting compartment, and a vertical frame is fixedly installed at the bottom of the base frame. The vertical frame is fixedly connected to the vertical end of the frame by fastening rods.

[0015] Preferably, a method for preventing pressure loss using a paper roll ejector for partitioning in an automated warehouse includes the following steps:

[0016] S1. The swing arm swings instantaneously at a specified amplitude and pulls the connecting belt. The connecting belt drives the shaft to rotate at high speed. The centripetal force generated at this time overcomes the elastic force of the elastic roll.

[0017] S2. The rocker arm deflects until it touches the limit rod. As the gear plate rotates, the rocker arm pushes the slide rod. The slide rod drives the sliding sleeve to slide along the arc rod and compress the spring. During this process, the slide rod provides a pushing force to the limit frame through the cooperation of the convex rod and the slide groove.

[0018] S3. The limit bracket swings until the toothed edge of the limit bracket engages with the gear plate, thereby locking the gear plate and the shaft, thus limiting the subsequent swing of the swing arm.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] 1. In this application, under normal circumstances, the push cylinder drives the swing arm to rotate, the swing arm pulls the connecting belt, and the connecting belt drives the take-up drum and shaft to rotate at a constant speed. At this time, the swing arm remains stable under the action of the elastic shaft. After the push cylinder suddenly loses pressure, the swing arm swings momentarily with a specified amplitude and pulls the connecting belt. The connecting belt drives the shaft to rotate at high speed. The centripetal force generated at this time overcomes the elastic force of the elastic shaft, and the swing arm deflects until it abuts the limit rod. As the gear plate rotates, the swing arm pushes the slide rod, and the slide rod drives the sliding sleeve to slide along the arc-shaped rod and compress the spring. During this process, the sliding sleeve... The rod provides a pushing force to the limiting frame through the cooperation of the convex rod and the sliding groove. The limiting frame swings until the toothed edge of the limiting frame engages with the gear plate, thereby locking the gear plate and the shaft. This limits the subsequent swing of the swing arm. The hardware such as the gear plate, the limiting frame, and the sliding rod are used to deal with the pressure loss of the push cylinder, making the overall pressure loss prevention effect more stable. Afterwards, you only need to move the swing frame to one side of the connecting chamber. At this time, the constraint of the connecting band between the connecting chamber and the swing arm is reduced. Tightening the spring will drive the shaft to reset counterclockwise, and the gear plate will contact and lock with the limiting frame, ensuring the ease of resetting the pressure loss prevention device.

[0021] 2. In this application, after the slide rod drives the slide sleeve to move a specified distance along the arc rod, the moving contact on the slide sleeve is exactly engaged with the stationary contact on the plate. At this time, the audible and visual alarm is activated, which allows the operator to quickly connect the fault of the paper kicker in this area. Subsequently, after the toothed plate and the limit frame are locked in contact, the slide sleeve will be reset under the action of the spring, and the moving contact and the stationary contact will separate, causing the audible and visual alarm to stop operating.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-5 The present invention provides a technical solution:

[0031] A pressure-loss prevention device for a paper roll partitioning system in an automated warehouse includes a frame 1, a swing arm 2, and a push cylinder 3. A connecting compartment 5 is fixedly installed on the outer wall of the vertical end of the frame 1. A shaft 12 is rotatably connected to the inner wall of the connecting compartment 5. A take-up drum 14 and a toothed disc 16 are fixedly installed on the outer wall of the shaft 12. A tension spring 13 is fixedly installed between the outer wall of the shaft 12 and the inner wall of the connecting compartment 5. A connecting strip 7 is wound around the outer wall of the take-up drum 14. The open end of the connecting strip 7 is fixedly connected to the outer wall of the swing arm 2. A fixed seat 20 is fixedly installed on the inner wall of the bottom of the connecting compartment 5. A limit frame 15 is rotatably connected to the outer wall of the fixed seat 20. The outer wall of the limit frame 15 is provided with a toothed edge 17. A linkage component for triggering the limit frame 15 is provided between the fixed seat 20 and the toothed disc 16.

[0032] A method for preventing pressure loss using a paper roll ejector for partitioning in an automated warehouse includes the following steps:

[0033] S1, the swing arm 2 swings instantaneously with a specified amplitude and pulls the connecting belt 7. The connecting belt 7 drives the shaft 12 to rotate at high speed. The centripetal force generated at this time overcomes the elastic force of the elastic roll.

[0034] S2, the swing arm 23 deflects until it comes into contact with the limit rod 22, and as the gear plate 16 rotates, the swing arm 23 pushes the slide rod 21, the slide rod 21 drives the slide sleeve 24 to slide along the arc rod 26 and compress the spring 27. During this process, the slide rod 21 provides a pushing force to the limit frame 15 through the cooperation of the protrusion rod 18 and the slide groove 19.

[0035] S3, the limiting frame 15 swings until the toothed edge 17 of the limiting frame 15 engages with the gear plate 16, thereby locking the gear plate 16 and the shaft 12, thus limiting the subsequent swing of the swing arm 2.

[0036] Under normal circumstances, the push cylinder 3 drives the swing arm 2 to rotate, the swing arm 2 pulls the connecting belt 7, and the connecting belt 7 drives the winding drum 14 and the shaft 12 to rotate at a constant speed. At this time, the swing rod 23 remains stable under the action of the elastic shaft. After the push cylinder 3 suddenly loses pressure, the swing arm 2 swings momentarily with a specified amplitude and pulls the connecting belt 7. The connecting belt 7 drives the shaft 12 to rotate at high speed. The centripetal force generated at this time overcomes the elastic force of the elastic shaft, and the swing rod 23 deflects until it abuts the limit rod 22. With the rotation of the gear plate 16, the swing rod 23 pushes the slide rod 21. The slide rod 21 drives the sliding sleeve 24 to slide along the arc rod 26 and compress the spring 27. During this process, the slide rod 21 passes through the convex The rod 18 and the slide 19 cooperate to provide a pushing force to the limit frame 15. The limit frame 15 swings until the toothed edge 17 of the limit frame 15 engages with the gear plate 16, thereby locking the gear plate 16 and the shaft 12, thus limiting the subsequent swing of the swing arm 2. The loss of pressure of the push cylinder 3 is dealt with by the hardware such as the gear plate 16, the limit frame 15 and the slide 21, making the overall anti-loss of pressure effect more stable. Afterwards, the swing arm 2 only needs to be moved to one side of the connecting chamber 5. At this time, the constraint of the connecting band 7 between the connecting chamber 5 and the swing arm 2 is reduced, and the spring 13 will drive the shaft 12 to reset counterclockwise. The gear plate 16 will be unlocked from the limit frame 15, ensuring the convenience of resetting the anti-loss of pressure device.

[0037] It should be noted that the linkage structure between the push cylinder 3 and the swing arm 2 is directly referenced from the comparison document, and therefore will not be elaborated here.

[0038] Specifically, such as Figure 2 and Figure 4As shown, the linkage assembly includes a rocker arm 23 and a slide rod 21. The rocker arm 23 is rotatably connected to the rear end face of the gear disc 16 via an elastic rotating shaft. The slide rod 21 is slidably connected to the fixed seat 20, and the front end face of the slide rod 21 is provided with a pushing part for axially pushing the limit frame 15. A limit rod 22 is provided on the outer side of the rocker arm 23. The limit rod 22 is integrally formed with the gear disc 16. An arc-shaped rod 26 is fixedly installed on the inner surface wall of the fixed seat 20. A sliding sleeve 24 fixedly connected to the slide rod 21 is slidably connected to the outer surface wall of the arc-shaped rod 26. A spring 27 is fixedly installed between the sliding sleeve 24 and the inner surface wall of the fixed seat 20. The pushing part includes a protruding rod 18 fixedly connected to the slide rod 21. The protruding rod 18 is connected to the inner surface of the limit frame 15 via a sliding groove 19. With the sliding connection on the surface wall, after the sudden loss of pressure in the push cylinder 3, the swing arm 2 swings momentarily with a specified amplitude and pulls the connecting belt 7. The connecting belt 7 drives the shaft 12 to rotate at high speed. The centripetal force generated at this time overcomes the elastic force of the elastic roll, and the swing arm 23 deflects until it abuts against the limit rod 22. As the gear plate 16 rotates, the swing arm 23 pushes the slide rod 21. The slide rod 21 drives the sliding sleeve 24 to slide along the arc rod 26 and compress the spring 27. During this process, the slide rod 21 provides a pushing force to the limit frame 15 through the cooperation of the protrusion rod 18 and the slide groove 19. The limit frame 15 swings until the toothed edge 17 of the limit frame 15 engages with the gear plate 16, thereby locking the gear plate 16 and the shaft 12.

[0039] Specifically, such as Figure 2 and Figure 3 As shown, an audible and visual alarm 6 is fixedly installed on the top of the connecting compartment 5. A latching plate 28 is fixedly installed on the inner wall of the fixed base 20. The sliding sleeve 24 and the outer wall of the latching plate 28 are respectively provided with a moving contact 25 and a stationary contact 29. After the sliding rod 21 drives the sliding sleeve 24 to move a specified distance along the arc rod 26, the moving contact 25 on the sliding sleeve 24 is exactly engaged with the stationary contact 29 on the latching plate 28. At this time, the audible and visual alarm 6 is activated, so that the operator can quickly know the fault of the paper ejector in this area. After the toothed disc 16 and the limit frame 15 are locked, the sliding sleeve 24 will be reset under the action of the spring 27, and the moving contact 25 and the stationary contact 29 will separate, so that the audible and visual alarm 6 stops operating.

[0040] Specifically, such as Figure 1 and Figure 2 As shown, the arc-shaped end of the connecting compartment 5 is connected to a cover 8. The outer wall of the cover 8 is integrally formed with a strip 9. The strip 9 is fixedly connected to the connecting compartment 5 by a locking rod 10, which facilitates internal maintenance of the connecting compartment 5. A base frame 4 is fixedly installed at the bottom of the connecting compartment 5. A vertical frame 11 is fixedly installed at the bottom of the base frame 4. The vertical frame 11 is fixedly connected to the vertical end of the frame 1 by a fastening rod, which facilitates the assembly and disassembly of the connecting compartment 5.

[0041] Working principle: Under normal circumstances, the push cylinder 3 drives the swing arm 2 to rotate, and the swing arm 2 pulls the connecting belt 7. The connecting belt 7, in conjunction with the winding drum 14 and the shaft 12, rotates at a constant speed. At this time, the swing arm 23 remains stable under the action of the elastic shaft. After the push cylinder 3 suddenly loses pressure, the swing arm 2 swings momentarily with a specified amplitude and pulls the connecting belt 7. The connecting belt 7 drives the shaft 12 to rotate at high speed. The centripetal force generated at this time overcomes the elastic force of the elastic shaft, and the swing arm 23 deflects until it abuts the limit rod 22. As the gear plate 16 rotates, the swing arm 23 pushes the slide rod 21. The slide rod 21 drives the sliding sleeve 24 to slide along the arc rod 26 and compress the spring 27. During this process, the slide rod 21 provides a pushing force to the limit frame 15 through the cooperation of the protrusion rod 18 and the sliding groove 19. The limit frame 15 swings until the toothed edge 17 of the limit frame 15 engages with the gear plate 16, thereby locking the gear plate 16 and the shaft 12, thus restricting the swing arm. 2. Subsequent swinging is addressed by hardware such as the gear plate 16, limit frame 15, and slide rod 21 to counteract the pressure loss of the push cylinder 3, making the overall pressure loss prevention effect more stable. Furthermore, afterward, simply moving the swing arm 2 to one side of the connecting compartment 5 reduces the constraint of the connecting band 7 between the connecting compartment 5 and the swing arm 2. The spring 13 will drive the shaft 12 to reset counterclockwise, and the gear plate 16 will unlock from the limit frame 15, ensuring the ease of resetting the pressure loss prevention device. After the slide rod 21 drives the sliding sleeve 24 to move a specified distance along the arc rod 26, the moving contact 25 on the sliding sleeve 24 will engage with the stationary contact 29 on the overlapping plate 28. At this time, the audible and visual alarm 6 will activate, allowing the operator to quickly know about the fault of the paper ejector in this area. Subsequently, after the gear plate 16 and the limit frame 15 are locked, the sliding sleeve 24 will reset under the action of the spring 27, and the moving contact 25 will separate from the stationary contact 29, causing the audible and visual alarm 6 to stop operating.
