Description

Technical Field

[0001] This utility model relates to the field of packaging, and in particular to a cylindrical paper tray feeding device. Background Technology

[0002] Cylindrical tissues are made by rolling stacked tissues to a certain thickness into a cylindrical shape and packing them into a cylindrical box. The square packaging is similar to the square shape of facial tissues. It is a relatively traditional packaging method. Because it takes up a lot of space, it is not suitable for use in cars or other places with limited storage space. However, cylindrical tissues can be stored upright, which makes them popular with consumers.

[0003] Since cylindrical paper is relatively small, it is usually sold in bulk in paper trays. Currently, the packaging of cylindrical paper in paper trays is still done manually. From opening the paper tray to putting multiple cylindrical paper into it, the entire process is done manually, which is inefficient and costly. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a cylindrical paper feeding device that enables automatic packaging of cylindrical paper.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a cylindrical paper tray feeding device, characterized in that it includes a paper tray conveyor belt, a cylindrical paper conveyor belt, and a finished product conveyor belt, wherein the paper tray conveyor belt is connected to the cylindrical paper conveyor belt and the finished product conveyor belt respectively; the cylindrical paper conveyor belt includes an inlet end and an outlet end, wherein the outlet end is provided with a pusher plate with a power source, and the pusher plate's push path is perpendicular to the conveying path of the finished product conveyor belt; the paper tray conveyor belt has suction holes evenly distributed on its working surface, and the paper tray conveyor... The conveyor belt has a paper tray forming and discharge station, which is equipped with a paper tray forming device. The paper tray forming device includes a lifting and suction component, a paper tray side forming block for unfolding and shaping the side of the paper tray, and a platen for fully opening the bottom of the paper tray. The lifting and suction component is located above the paper tray conveyor belt, the paper tray side forming block is located on both sides of the pushing path, the paper tray side forming block is connected to a longitudinal straight push drive component, and the platen is located behind the paper tray side forming component and is connected to a swing drive component.

[0006] This utility model uses a paper tray conveyor belt to intermittently transport paper trays. The paper trays at the feeding station are sent to the forming and discharging station. The lifting and suction components open the paper trays vertically. The forming blocks on both sides of the paper tray move relative to each other to shape the sides of the paper tray. Then, the flat plate taps the bottom of the paper tray to fully open it, realizing automatic opening of the paper tray. According to the specifications of the paper tray, the pusher plate pushes the corresponding number of cylindrical paper from the cylindrical paper conveyor belt into the paper tray, realizing automatic packaging of cylindrical paper, improving efficiency and reducing labor costs.

[0007] Preferably, a lifting relay pusher is provided behind the lifting adsorption component to take over from the pusher plate in pushing the finished product. The lifting adsorption component and the lifting relay pusher are respectively connected to the first transverse drive component. The pusher plate pushes the cylindrical paper into the paper tray and then returns to its original position. The lifting adsorption component and the lifting relay pusher work together to deliver the packaged finished product into the paper tray. When the lifting relay pusher pushes the finished product, the pusher plate can be reset in advance to reduce waiting time and improve efficiency.

[0008] Preferably, the paper tray side forming block is mounted on the mounting plate, the longitudinal push drive drives the mounting plate to move longitudinally, and the flat plate is hinged to the mounting plate. Two flat plates are mounted on the mounting plates on both sides of the pushing path, and these two flat plates flatten the bottom sides of the paper tray, resulting in more even force distribution on the paper tray and preventing wrinkles that could affect its appearance.

[0009] Preferably, a guide block conforming to the unfolded shape of the paper tray is provided between the paper tray conveyor belt and the finished product conveyor belt. The guide block has a through groove to facilitate the passage of cylindrical paper. Multiple cylindrical paper rolls enter the paper tray through the guide block, preventing the cylindrical paper rolls from being left in the gap between the paper tray conveyor belt and the finished product conveyor belt, and ensuring continuous operation of the equipment.

[0010] Based on the guide block, the guide block is equipped with a gathering strip that assists the cylindrical paper in entering the paper tray. The gathering strip is arranged along the pushing direction of the pusher plate, and the guide block is connected to a second transverse drive component. The second transverse drive component drives the gathering strip on the guide block into the paper tray, ensuring that multiple cylindrical papers accurately enter the paper tray.

[0011] The structure includes a gathering strip, which is a spring sheet. The spring sheet provides a certain force to keep multiple cylindrical sheets close together.

[0012] Preferably, the outlet of the cylindrical paper conveyor belt is connected to a lifting and stacking device, which includes a storage bin and a lifting platform. The storage bin is located in front of the pusher plate, and the lifting platform is located below the storage bin. The storage bin is positioned above the lifting platform. The lifting platform feeds the cylindrical paper into the storage bin, which holds the cylindrical paper to be pushed, preventing the pusher block from colliding with other cylindrical paper on the conveyor belt during the pushing process and ensuring normal machine operation.

[0013] Based on the lifting and stacking device, the storage bin is equipped with a left baffle and a right baffle below it. One-way passage blocks are oscillating on the left and right baffles, and the two one-way passage blocks move relative to each other. The one-way passage blocks allow rising cylindrical paper to pass through, preventing the cylindrical paper placed in the storage bin from falling and ensuring that the cylindrical paper to be pushed is in the discharge bin. At the same time, the one-way passage blocks can work with the lifting platform to place multiple layers of cylindrical paper in the storage bin, meeting the needs of different packaging specifications.

[0014] Based on the one-way passage block, the one-way passage block is connected to the left and right baffles respectively by spring components. The spring components enable the one-way passage block to only allow the upward-moving cylindrical paper to pass through, resulting in a simple structure. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. The X-axis is the vertical axis, the Y-axis is the horizontal axis, and the Z-axis is the vertical axis.

[0023] like Figure 1The illustrated cylindrical paper feeding device includes a paper tray conveyor belt 1, a cylindrical paper conveyor belt 2, and a finished product conveyor belt 3. The paper tray conveyor belt 1 and the cylindrical paper conveyor belt 2 intermittently convey paper. The paper tray conveyor belt 1 is connected to both the cylindrical paper conveyor belt 2 and the finished product conveyor belt 3, and is positioned between the cylindrical paper conveyor belt 2 and the finished product conveyor belt 3. The paper tray conveyor belt 1, the cylindrical paper conveyor belt 2, and the finished product conveyor belt 3 are arranged parallel to each other. The cylindrical paper conveyor belt 2 includes an inlet end and an outlet end. The inlet end is connected to the cylindrical paper production equipment or the cylindrical paper is placed manually. The outlet end is equipped with a pusher plate 4 with a power source. The pusher plate 4 is slidably mounted on the first crossbeam of the frame. The pusher plate 4 pushes the cylindrical paper on the cylindrical paper conveyor belt 2 onto the paper tray 11 for conveying. The pushing path of the pusher plate 4 is perpendicular to the conveying path of the finished product conveyor belt 3.

[0024] like Figure 2 As shown, the paper tray conveyor belt 1 has suction holes 101 evenly distributed on its working surface. The paper tray conveyor belt 1 has a paper tray forming and discharging station. The suction holes 101 are connected to a negative pressure source to suction the lower surface of the paper tray 11, preventing the paper tray 11 from shifting. The paper tray 11 on the paper tray conveyor belt 1 can be placed manually or automatically. A paper tray hopper is set above the inlet end of the paper tray conveyor belt 1. The paper tray 11 in the hopper is sent to the paper tray conveyor belt 1 by suction cups set on the swing arm. Alternatively, a suction cup with a lifting power source is set below the paper tray conveyor belt 1 to pick up the paper tray 1 from above and move it down to send the paper tray 11 to the paper tray conveyor belt 1.

[0025] The paper tray forming and discharging station is equipped with a paper tray forming device 5. The paper tray forming device 5 includes a lifting suction component 51, a paper tray side forming block 52 for unfolding and shaping the sides of the paper tray, and a flat plate 53 for fully opening the bottom of the paper tray 11. The lifting suction component 51 is positioned above the paper tray conveyor belt 1 and is a movable rod with multiple suction cups connected to a lifting power source, which can be a motor or a cylinder. The paper tray side forming blocks 52 are positioned on both sides of the pushing path and are connected to a longitudinal push drive component. The paper tray side forming blocks 52 conform to the shape of the paper tray side and are positioned on both sides of the paper tray forming and discharging station, facing each other. The movement, in coordination, opens the sides of the paper tray 11, initially shaping the paper tray 11. The striking plate 53 is positioned behind the formed sides of the paper tray and is connected to the first swing drive component. The striking plate 53 can be oscillating above the paper tray conveyor belt 1 to strike the bottom of the paper tray 11. Alternatively, the paper tray side forming block 52 can be mounted on the mounting plate, and the longitudinal push drive component drives the mounting plate to move longitudinally. The striking plate 53 is hinged to the mounting plate, and the swing drive component is mounted on the mounting plate. The two striking plates 53 on both sides move relative to each other. After the paper tray side forming block 52 shapes the sides of the paper tray 11, the two striking plates 53 strike the two ends of the bottom of the paper tray 11, finally opening the paper tray 11. This method of striking the paper tray 11 results in more even force distribution, preventing paper wrinkles and ensuring the aesthetic appearance of the paper tray 11.

[0026] To improve efficiency by allowing the pusher block to reset earlier, a lifting relay pusher is provided behind the lifting adsorption component 51 to take over pushing the finished product from the pusher plate 4. The lifting relay pusher is connected to a second lifting power source. After the pusher block pushes the cylindrical paper into the paper tray 11 and resets, the lifting relay pusher descends. The lifting adsorption component 51 and the lifting relay pusher are respectively connected to a first transverse drive component 61. The first transverse drive component 61 is mounted on a first crossbeam, the lifting adsorption component 51 is mounted on a first slider, and the lifting relay pusher is mounted on a second slider. The first transverse drive component 61 is driven by a gear belt. The first and second sliders are located on the same side of the belt. The motor drives the lifting adsorption component 51 and the lifting relay pusher to move simultaneously, delivering the finished product to the finished product conveyor belt 3. The pusher plate 4 and the lifting relay pusher push the material alternately, reducing the stroke of the pusher plate 4 and improving efficiency.

[0027] like Figure 4As shown, to prevent cylindrical paper from falling into the gap between the paper tray conveyor belt 1 and the finished product conveyor belt 3, causing a malfunction and shutdown, a guide block 7 conforming to the unfolded shape of the paper tray 11 is provided between the paper tray conveyor belt 1 and the finished product conveyor belt 3. The guide block 7 has a through groove to facilitate the passage of cylindrical paper. The shape of the guide block 7 conforms to the shape of the paper tray 11, keeping multiple cylindrical paper in a gathered state, thus accurately entering the paper tray 11. Furthermore, the bottom of the guide block 7 can connect the paper tray conveyor belt 1 and the finished product conveyor belt 3, facilitating the passage of cylindrical paper and ensuring continuous operation of the equipment.

[0028] To ensure that multiple cylindrical paper rolls accurately enter the paper tray 11, the guide block 7 is equipped with a gathering strip 71 that facilitates the entry of the cylindrical paper rolls into the paper tray 11. The gathering strip 71 is arranged along the pushing direction of the pusher plate 4. The guide block 7 is connected to a second transverse drive component. The second transverse drive component can be a cylinder, a motor, or other linear motion mechanism. The second transverse drive component drives the guide block 7 to move to the left, causing the gathering strip 71 to enter the paper tray 11. The gathering strip 71 is a spring sheet or other component with elasticity and shape recovery properties. The gathering strip 71 makes the inlet of the guide channel in the guide block 7 larger than the outlet, facilitating the entry of the cylindrical paper rolls into the guide block 7, while ensuring that the cylindrical paper rolls enter the paper tray 11.

[0029] To ensure normal equipment operation, the pusher block may collide with other cylindrical paper tubes during the pushing or resetting process, damaging the outer surface of the packaging and affecting its appearance. In some cases, the pusher block may even fail to reset properly, causing equipment malfunction and shutdown. The outlet of the cylindrical paper conveyor belt 2 is connected to a lifting and stacking device 8, which includes a storage bin 81 and a lifting platform 82. The storage bin 81 is located in front of the pusher plate 4 and consists of two side plates. The pusher plate 4 is positioned between the two side plates. The lifting platform 82 is located below the storage bin and is connected to a second lifting power source. The lifting platform 82 moves up and down between the two side plates. Initially, there is a waiting area between the storage bin 81 and the lifting platform 82. The lifting platform 82 moves the waiting area upwards into the storage area, waiting for the pusher plate 4 to push it into the paper tray 11. The cylindrical paper to be fed into the paper tray 11 is separated from other cylindrical paper. The pusher plate 4 moves the cylindrical paper in the storage bin 81. In this way, the pusher plate 4 will not scratch the outer surface of the cylindrical paper, and other cylindrical paper will not obstruct the movement of the pusher plate 4, ensuring the normal operation of the equipment.

[0030] like Figure 5As shown, in order to adapt to the packaging requirements of different specifications, a left baffle and a right baffle are provided below the storage bin 81. One-way passage blocks 9 are respectively oscillating on the left baffle 83 and the right baffle 84. The one-way passage blocks 9 mean that the blocks only allow the upward-moving cylindrical paper to pass through, preventing the cylindrical paper from falling from the storage bin 81. The left and right baffles are respectively set on both sides of the cylindrical paper conveyor belt 2. The two one-way passage blocks 9 move relative to each other. The distance between the two blocks is less than the length of the cylindrical box, but greater than the length of the lifting platform 82. This will not hinder the movement of the lifting platform 82 and prevent the cylindrical paper from falling. During the pushing interval of the pusher plate 4, the number of layers of cylindrical paper is increased by the upward movement of the lifting platform 82. Specifically, the lifting platform 82 moves the first layer of cylindrical paper into the storage bin 81, then lowers, positioning the first layer of cylindrical paper on the one-way passage blocks 9 on both sides. The lifting platform 82 then resets, and the cylindrical paper conveyor belt 2 continues to feed the cylindrical paper onto the lifting platform 82. The lifting platform 82 then moves the second layer of cylindrical paper into the storage bin. At this point, the storage bin contains two layers of cylindrical paper. The pusher plate 4 then feeds the two layers of cylindrical paper into the paper tray 11, accommodating different specifications. The one-way passage blocks 9 can be connected to a swing power source. When the lifting platform 82 moves upward, the swing power source drives the one-way passage blocks 9 to avoid obstacles. When the cylindrical paper reaches the storage bin, the one-way passage blocks 9 reset, preventing the cylindrical paper from falling into the storage bin. However, this solution is costly. Alternatively, the one-way passage block 9 is connected to the left and right baffles respectively via spring members 10. The two one-way passage blocks 9 are hinged to the left and right baffles respectively, and spring members 10 are provided between the one-way passage block 9 and the left and right baffles. When the lifting platform 82 carries the cylindrical paper upward, the spring member 10 deforms, causing the two one-way passage blocks 9 to move away from each other until the cylindrical paper reaches the storage bin. Then the spring member 10 returns to its original state, allowing the cylindrical paper blocked by the passage block in the storage bin to fall down. This structure is simple and low in cost.

[0031] The working principle of this utility model is described below with reference to the accompanying drawings: After the paper tray conveyor belt 1 delivers the paper tray 11 to the paper tray forming and discharging station, it stops conveying. The suction holes 101 of the paper tray conveyor belt 1 suction the lower surface of the paper tray 11, and the lifting suction member 51 moves down to suction the upper surface of the paper tray 11 and moves up, causing the paper tray 11 to open up and down. The two paper tray side forming blocks 52 move relative to each other, opening the side of the paper tray 11. Then, the flattening block taps the two ends of the bottom of the paper tray 11, causing the paper tray 11 to open completely. Subsequently, the guide block 7 moves towards the paper tray 11, extending the gathering strip 71 into the paper tray 11.

[0032] The cylindrical paper conveyor belt 2 delivers several cylindrical papers to the lifting platform 82. The lifting platform 82 moves upward, and the spring component 10 deforms under force, causing the two one-way passage blocks 9 to move away from each other, and the cylindrical papers enter the storage bin 81. If multiple layers of cylindrical papers are needed, the lifting platform 82 descends, and the one-way passage blocks 9 reset to support the cylindrical papers until the lifting platform 82 delivers the next layer of cylindrical papers. Once the storage bin 81 contains the corresponding number of cylindrical papers, the pusher plate 4 pushes the corresponding number of cylindrical papers through the guide block 7 into the paper tray 11. Subsequently, the pusher plate 4 returns to its original position, and the lifting relay pusher plate moves down to the cylindrical paper position. The lifting relay pusher plate, in conjunction with the lifting suction component 51, delivers the packaged cylindrical papers on the paper tray conveyor belt 1 to the finished product conveyor belt 3, and is then discharged by the finished product conveyor belt 3.
