Abstract
Description
Technical Field
[0001] This invention relates to the field of stacking, and more specifically to a stacking device for tissue paper production. Background Technology
[0002] Paper towels are a very practical daily necessity, usually packaged in boxes or bags, and their production is now automated. During production, pre-packaged paper towels are conveyed on a conveyor belt to a stacking terminal, where they are finally stacked into piles for easy packaging into boxes.
[0003] Currently, the final packaging process, which involves packing tissue boxes, has not yet been automated with the conveyor belt. Instead, the tissue packs are transported to one location by the conveyor belt and then manually stacked before being packaged. This has become a weak link that restricts overall production efficiency. Summary of the Invention
[0004] In response to the problems raised in the background art, the present invention provides a stacking device for paper towel production to solve these problems, and the present invention will be further described below.
[0005] A stacking device for paper towel production includes a base and a conveyor table. A stacking rack is slidably mounted on the base. The stacking rack has an inlet on the side facing the conveyor table and is connected to the inlet. A push rod is mounted on the base, and the output end of the push rod is connected to the stacking rack. A second push rod is mounted on the base, and the output end of the second push rod is connected to a push plate. A placement plate is also connected to one side of the base.
[0006] Preferably, a guide frame is slidably mounted on the base, and a sliding groove is provided on the base. An electric slider is provided at one point on the sliding groove, and the guide frame is connected to the electric slider. Due to the presence of the guide frame, when the tissue stack moves into position, the tissue stack stops due to the presence of the guide frame and will not tip over due to inertia.
[0007] Preferably, a frame is connected to the base, a top plate is connected to the frame, and symmetrical corner plates are connected downwards to the top plate, with the stirring section forming a triangle. During the process of the stacking rack pushing out the stacked tissue packs, one side of the corner plate adheres to the inner walls of both sides of the stacking rack, which can remove tissues that are stuck to the inner walls of the stacking rack due to static electricity or falling from the panel. The symmetrically arranged triangular corner plates can neatly center the tissues within the stacking rack.
[0008] Preferably, the top plate is provided with a second sliding groove, and a slider is provided within the second sliding groove. The corner plate is connected to the slider, and the slider can be controlled to slide within the second sliding groove. When the tissues fall into the stacking rack, the corner plate remains stationary at the tissue outlet of the stacking rack to prevent the stacked tissues from tipping outward. When the tissues are moved outward, the corner plate adheres to the inner wall of the stacking rack, serving to remove the removed tissues from the inner wall and center them. At the same time, when the corner plate is at the tissue outlet of the stacking rack, it also works with the guide frame to prevent the pushed-out stack of tissues from tipping over.
[0009] Preferably, the slide groove two has a built-in slide rod one, the slider is slidably mounted on the slide rod one, the slide rod one is fitted with a spring one, the output end of the push rod one is connected to a flat push plate, the top of the flat push plate is connected to a push rod, the push rod includes a straight rod section and an inclined rod section connected to each other, which is intended to adjust the position of the slider through mechanical linkage.
[0010] Preferably, a mounting platform is connected to one side of the conveyor, and sensors and a motor are installed on the mounting platform. The output end of the motor is connected to a rotating beam, and a lever is connected to the rotating beam. A clearance groove is provided on one side of the conveyor. The purpose is to push the tissue packs away from the conveyor at high speed through the lever mechanism, so that they enter the stacking rack in a horizontal state after leaving the conveyor.
[0011] Preferably, the top plate is connected to slide rails on both sides, and the slide rails have built-in slide rods. A horizontal bar is slidably mounted on the slide rods, which lies across the front of the conveyor. The horizontal bar can be raised and lowered under control. When the tissues move with the conveyor and reach the horizontal bar, they are intercepted and held in place by the horizontal bar. At this time, the horizontal bar and the conveyor can work together to adjust the tissues into a stacked state. After being detected by a sensor, the horizontal bar is raised under control and no longer intercepts the tissues.
[0012] Preferably, the levers are configured as at least two parallel ones, designed to ensure that the tissues are stacked when pushed away.
[0013] Preferably, an extension rod is connected to one side of the horizontal bar, and a rotating column is connected to the rotating beam. The rotating column is provided with a sliding groove three, and the end of the extension rod is slidably fitted in the sliding groove three. A spring two is sleeved on the sliding rod two. This design aims to ensure that the horizontal bar is raised when the lever strikes the tissue paper through a mechanical linkage.
[0014] Beneficial effects: Compared with the prior art, the present invention realizes the stacking and packaging of tissues in an automated manner. The corner plate is located at the tissue outlet of the stacking rack before the push rod is activated, which plays a role in preventing the falling and pushing of the tissue stacks. After the push rod is activated, it moves to the side and fits against the inner wall of the stacking rack, which plays a role in shoveling the removed tissues away from the inner wall and centering them. Through the linkage between the horizontal bar and the rotating beam, it is ensured that the tissue packs enter the stacking rack in a stacked state. Attached Figure Description

Detailed Implementation
[0023] Next, we will combine the appendix Figures 1-7 A specific embodiment of the present invention will be described in detail below.
[0024] Reference Appendix Figure 1 and Figure 2 A stacking device for tissue paper production includes a base 1 and a conveyor 2. A stacking rack 3 is slidably mounted on the base 1. The stacking rack 3 is composed of three panels connected together, and an inlet 301 is provided on the side of the rack facing the conveyor 2. The stacking rack 3 is connected to the inlet 301. After the tissue paper package conveyed on the conveyor 2 leaves the conveyor 2, it enters the stacking rack 3 through the inlet 301. The shape of the stacking rack 3 is adapted to the tissue paper package, and the tissue paper automatically stacks after falling into the stacking rack 3.
[0025] A push rod 4 is mounted on the base 1, and the output end of the push rod 4 is connected to the stacking rack 3. When the number of tissue packs stacked in the stacking rack 3 reaches the target number (at this time, the top layer of tissues is still below the feed inlet 301), the push rod 4 is activated to move the stacking rack 3. The stacking rack 3 moves together with the tissues inside it, and the distance it moves is greater than the length of a single tissue pack, that is, pushing the stacked tissues away from the original stacking position. When it is pushed out to the correct position, the stacking rack 3 resets, and the stack of tissue packs that were pushed out remains on the base 1. After the stacking rack 3 resets, it continues the subsequent operation of collecting and stacking tissues. The tissues pushed out later will first act on the previously pushed tissue stack, pushing the previously pushed tissue stack forward by the length of one tissue pack, and so on.
[0026] Reference Appendix Figure 1 and Figure 3 As is common knowledge, stacked tissues have inertia during movement. When the stacking rack is in place, the tissue stack will continue to move forward due to inertia. In this embodiment, to ensure efficiency, the pushing speed is relatively fast, making the tissue stack very prone to tipping over. Based on this, this embodiment has a guide frame 5 slidably mounted on the base 1. The base 1 has a sliding groove 501, and an electric slider is located at one point in the sliding groove. The guide frame 5 is connected to the electric slider. Initially, the guide frame 5 is located near the end of the stacking rack 3. When the first stack of tissues is pushed out, it first contacts the guide frame 5, and then the guide frame 5 moves together with the tissue stack. Due to the presence of the guide frame 5, when the tissue stack moves into place, the push rod 4 resets the stacking rack, and the tissue stack stops due to the presence of the guide frame 5, preventing it from tipping over due to inertia. As subsequent tissue stacks are pushed out, the guide frame 5 also gradually moves forward to provide an anti-tipping function for all tissue stacks.
[0027] Reference Appendix Figure 1 and Figure 2 The base 1 is equipped with a push rod 6, and the output end of the push rod 6 is connected to a push plate 7. A placement plate 8 is also connected to one side of the base 1. When the number of directly pushed stacks reaches the target quantity, the pushed tissue packs are arranged along the slide groove at the bottom of the base 1. Then, the packaging box is placed on the placement plate 8 with the open side for putting in the tissues facing the push plate 7. The push rod 6 is activated, and the push plate 7 pushes the stacked tissues into the packaging box. After retracting, the push plate 7 resets, and the guide frame 5 also resets under the action of the electric slider.
[0028] In practice, the entire production process of plastic tissue packs involves intense friction, contact, and separation at multiple stages. Based on the "triboelectric" effect, plastic tissue packs are highly prone to generating and accumulating static electricity during production. During automated stacking, static electricity can cause tissue packs to adhere to the inner wall of the stacking rack 3, making them difficult to detach. This results in the stacked tissue packs being pulled upside down when the stacking rack 3 retracts and resets. To eliminate this phenomenon, refer to the attached... Figure 1and Figure 4 In this embodiment, a frame 9 is connected to the base 1, a top plate 10 is connected to the frame 9, and symmetrical corner plates 11 are connected downwards to the top plate 10. The stirring cross-section is triangular. During the process of the stacking rack 3 pushing out the stacked tissue packs, one side of the corner plate 11 is attached to the inner walls of both sides of the stacking rack 3. As the tissue pack moves with the stacking rack 3, the corner plates 11 attached to both sides can remove the tissues that are attached to the inner walls of the stacking rack 3 due to static electricity or falling from the panel. At the same time, because the size of the stacking rack 3 is adapted to the tissues (but the size of the stacking rack is larger than the size of the tissues), the tissues that fall into the stacking rack 3 are stacked unevenly due to the randomness of their position. The symmetrically arranged triangular corner plates 11 can neatly center the tissues in the stacking rack 3.
[0029] As the tissues fall from the conveyor 2 onto the stacking rack 3, they gradually stack into a pile. Due to the randomness of the falling process, and the fact that the stacking rack is larger than the tissues, this embodiment uses the aforementioned corner plate 11 to limit the tissues during the stacking process to prevent them from tipping over. Specifically: refer to the attached... Figure 4 and Figure 5 The top plate 10 is provided with a second sliding groove 101, and a slider 12 is provided in the second sliding groove 101. The corner plate 11 is connected to the slider 12. The slider 12 can be controlled to slide in the second sliding groove 101. When the tissues fall into the stacking rack, the corner plate 11 moves towards the slider 12 until it stops at the tissue outlet of the stacking rack 3. At this time, the corner plate 11 limits the stacked tissues in the stacking rack 3 to prevent the stacked tissues from tipping outward. When the tissues are moved outward, the corner plate 11 moves away from the slider 12 until it is in contact with the inner wall of the stacking rack 3 and stops, which plays the role of scooping the removed tissues away from the inner wall and centering them. At the same time, when the corner plate is at the tissue outlet of the stacking rack 3, it also works with the guide frame 5 to prevent the pushed-out stack of tissues from tipping over.
[0030] In this embodiment, the position of slider 12 is adjusted by mechanical linkage. Specifically, refer to the attached diagram. Figures 4-6The slide groove 101 has a built-in slide rod 13. The slider 12 is slidably mounted on the slide rod 13. A spring 14 is sleeved on the slide rod 13. The output end of the push rod 4 is connected to a flat push plate 15. The top of the flat push plate 15 is connected to a push rod 16. The push rod 16 includes a straight rod section 161 and an inclined rod section 162 that are connected to each other. During the process of the tissues falling into the stacking rack 3, the push rod 4 does not move, and the slider 12 is in a close-up state under the action of the spring 14, located at the exit of the stacking rack 3. At this time, the flat push plate 15 is a certain distance from the stacking rack 3. When the push rod 4 moves, the flat push plate 15 moves towards the outer wall of the stacking rack 3. During this process, the inclined rod section 162 interacts with the slider 12, and the slider 12 moves backward due to the squeezing action. During this stage, the corner plate 11 is in an active state, and the stacking rack 3 is in a stationary state. When the slider 12 passes the inclined rod section 162 and interacts with the straight rod section 161, the slider 12 no longer moves, the corner plate 11 is in contact with the inner wall of the stacking rack 3, and the flat push plate 15 is in contact with the outer wall of the stacking rack 3. After this, the stacking rack 3, the push rod 4, and the tissues move together.
[0031] When the tissues fall into the stacking rack 3 after leaving the conveyor 2, it is necessary to ensure that the tissues fall smoothly. In this invention, this is achieved by adapting the size of the stacking rack to the tissues. Additionally, this embodiment uses a toggle mechanism to accelerate the speed at which the tissues leave the conveyor 2, allowing the tissues to leave the conveyor 2 horizontally and enter the stacking rack 3. (See attached diagram) Figure 1 and Figure 7 A mounting platform 17 is connected to one side of the conveyor 2. The mounting platform 17 is equipped with a sensor 18 and a motor 19. The output end of the motor 19 is connected to a rotating beam 20, and a lever 21 is connected to the rotating beam 20. A clearance groove 201 is provided on one side of the conveyor 2. When the tissue paper moves to the front of the conveyor 2 and is detected by the sensor 18, the motor 19 starts, driving the rotating beam 20 to rotate. The lever 21 rotates rapidly and passes over the clearance groove 201, striking the tissue paper package. This pushes the tissue paper package away from the conveyor 2 at high speed, allowing it to enter the stacking rack 3 in a horizontal position after leaving the conveyor 2.
[0032] The width of the conveyor 2 is greater than the width of the tissue pack, and the tissue pack lands on the conveyor 2 in a random state. In this embodiment, the tissue pack is pushed horizontally into the stacking rack 3 in a stacked state through the following technical solution: Slide rails 22 are connected to both sides of the top plate 10. Slide rails 22 have built-in slide rods 23, and a horizontal rod 24 is slidably mounted on slide rod 23. The horizontal rod 24 lies horizontally in front of the conveyor 2 and can be raised and lowered under control. When the tissue pack travels with the conveyor 2 to the horizontal rod 24, it is intercepted and held by the horizontal rod 24. At this time, the horizontal rod 24 and the conveyor 2 can jointly adjust the tissue pack into a stacked state. After being detected by the sensor 18, the horizontal rod 24 is raised under control, no longer intercepting the tissue pack. Simultaneously, the motor 19 starts, and the lever 21 rotates rapidly, pushing the tissue pack away from the conveyor 2 at high speed and into the stacking rack 3 in a stacked horizontal state.
[0033] To further ensure that the tissues are stacked when pushed away, the levers 21 are configured as at least two parallel levers.
[0034] A horizontal rod 24 is connected to an extension rod 25 on one side, and a rotating column 26 is connected to the rotating beam 20. The rotating column 26 has a sliding groove 261, and the end of the extension rod 25 is slidably fitted in the sliding groove 261. A spring 27 is sleeved on the sliding rod 23. When the motor 19 starts and drives the rotating beam 20 to rotate, the rotating column 26 rotates together with the rotating beam 20. Through the action of the sliding groove 261 and the extension rod 25, the horizontal rod 24 can be lifted upward. That is, the movement of the horizontal rod 24 is linked with the lever 21. The mechanical linkage ensures the accuracy of the movement, that is, the horizontal rod 24 is already lifted when the lever 21 hits the tissue.
[0035] In this invention, the stacking and packaging of tissues are automated. The corner plate is positioned at the tissue outlet of the stacking rack before the push rod is activated, preventing the falling and pushing tissue stacks from tipping over. After the push rod is activated, it moves laterally to fit against the inner wall of the stacking rack, shoveling the removed tissues away from the inner wall and centering them. The linkage between the horizontal bar and the rotating beam ensures that the tissue packs enter the stacking rack in a stacked state.
[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
