Abstract
Description
Technical Field
[0001] The utility model generally relates to the technical field of printed matter processing and transportation, in particular to a stacking device. Background Art
[0002] Printed books go through multiple steps during production and need to be transported between different workstations. To improve transport efficiency, intermediate products in the production process need to be palletized.
[0003] In some processes, the process of stacking the stacked books requires manual labor, which is inefficient and costly. For example, after the book signatures are processed into book blocks through book arrangement and sewing, the spine of the book block will rebound due to the structural elasticity of the paper, so pressure maintenance is required. After the book block is processed by the vertical book press, the book block remains vertically placed. In this case, it is not convenient for transportation, and the book block needs to be adjusted to a flat position. However, when the book block is thick and the paper used is thin, adjusting the posture of the book block will cause the side to be compressed, and the spine will become skewed. This situation is not only not conducive to stacking the stacked books, but the skewed state of the spine for a long time may also affect the quality of the book block. In the existing process, manual work is required to tidy the book block so that the sides of the book block are restored to a flush state. The action is simple and repeatable, but it requires manual work and is inefficient.

[0035] The following describes embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.
[0036] Figure 1 The structure of the stacking device 1 in some embodiments of the present invention is shown below. Figure 1 The stacking device 1 will be described.
[0037] like Figure 1 As shown, the stacking device 1 includes a first conveying device 11, a guiding device 12, an alignment device 13, and a stacking device 14. In this embodiment, the stacking device 1 is used to stack printed materials in volumes, wherein the printed materials in volumes refer to printed materials that have been arranged (multiple book signatures are arranged neatly in a preset order), and multiple book signatures are nested or stacked together. Furthermore, according to a preferred embodiment of the present invention, the printed materials in volumes refer to printed materials that are fixed at the spine position, such as multiple book signatures that have been sewn (stitched at the spine position with sutures). The stacking device 1 is used to stack multiple printed materials in volumes into stacks, so that the stacks can be placed on the boards and transported to other processing stations.
[0038] The first conveyor 11 can receive printed materials in bundles. For example, the first conveyor 11 is connected to a station in the previous process of the printed materials. After the printed materials are processed in the previous process, they are conveyed to the first conveyor 11. Connecting the first conveyor 11 to the station in the previous process allows the stacking device 1 to be integrated with the processing station, reducing the number of transfers of printed materials and also being used to adjust the production rhythm.
[0039] The first conveyor 11 drives the printed material, and in this embodiment, the printed material moves in a vertical position relative to the first conveyor 11. The vertical position means that the pages of the printed material are located in a vertical plane. For example, in some embodiments, the previous step in the printing process is a pressure holding process, in which a vertical book press is used to clamp and hold the printed material in a direction parallel to the pages. The printed material's spine is located on the bottom surface, with the fore-edge facing upward, and the printed material moves in a vertical position along the first conveyor 11.
[0040] The guide device 12 is disposed on the movement path of the first conveyor 11, for example, the guide device 12 is disposed above the first conveyor 11 or on the side of the first conveyor 11. In this embodiment, the guide device 12 can cause the printed matter to tilt toward both sides of the movement direction of the first conveyor 11, so that the printed matter moves with the first conveyor 11 in a posture parallel to the surface of the first conveyor 11. Preferably, the surface of the first conveyor 11 (the surface that contacts the printed matter, which can be continuous or intermittent) is approximately horizontal, and the guide device 12 adjusts the printed matter to lie flat along the horizontal surface. For example, in some embodiments, the spine of the printed matter is attached to the surface of the first conveyor 11. During the tilting process of the printed matter, the side of the spine located in the tilting direction is compressed and becomes skewed and deformed. When the printed matter is placed flat on the first conveyor 11, the spine remains skewed and deformed due to the friction between the pages, and is subsequently corrected using the alignment device 13.
[0041] In some embodiments, the guide device 12 can apply a force on one side of the printed product (the side on both sides of the movement direction of the first conveyor 11) to cause the printed product to tilt in that direction and lie flat on the first conveyor 11. Specifically, the guide device 12 includes a lever (not shown) suspended above the first conveyor 11. The lever is positioned at a distance from the surface of the first conveyor 11 that is less than the height of the printed product when placed vertically, so that the lever can act on the printed product.
[0042] The lever can be controlled to move vertically relative to the direction of movement of the first conveying device 11, for example Figure 1 As shown in FIG, the first conveying device 11 moves from right to left, and the shifting rod is controlled to Figure 1 The up-down direction movement in the machine makes the printed product tilt upward or tilt downward. Further, the lever can be manually controlled, or a motor and a control program can be utilized to automatically control the lever movement.
[0043] In other embodiments, the lever is configured to rotate relative to the first conveyor 11 in a controlled manner. During the rotation of the lever, the lever pushes the printed product to tilt on the first conveyor 11 so that the printed product is adjusted to a posture parallel to the surface of the first conveyor 11.
[0044] Preferably, the lever moves perpendicular to the movement direction of the first conveyor 11 so that after the printed matter is tipped over, the spine is parallel or perpendicular to the movement direction of the first conveyor 11, thereby preventing the printed matter from tilting on the first conveyor 11 and facilitating the alignment device 13 to correct deformation at the spine position.
[0045] According to a preferred embodiment of the present invention, the lever is configured to push the printed product toward either side of the moving direction of the first conveying device 11, for example Figure 1 The movement direction of the first conveying device 11 is from right to left, and the shifting rod is set to move Figure 1 The guide mechanism 12 is configured to move up and down in the first conveyor 11 to control the dumping direction and position of the printed materials on the first conveyor 11. Specifically, for example, the guide mechanism 12 may include a track perpendicular to the direction of movement of the first conveyor 11, along which the lever can move. Initially, the lever is positioned near the center of the first conveyor 11, and can cause the printed materials to dump upward or downward according to preset control logic.
[0046] In other embodiments, the guide device 12 is disposed near any side of the moving direction of the first conveyor 11, and pushes the printed matter to fall onto the first conveyor 11 so that the printed matter is close to the centerline of the first conveyor 11. Furthermore, the guide device 12 is configured to cause the position where the printed matter falls onto the first conveyor 11 to be close to the centerline of the first conveyor 11, thereby cooperating with the alignment device 13.
[0047] The alignment device 13 is provided along the moving direction of the first conveying device 11 and is located downstream of the guide device 12. The alignment device 13 can be pressed against the side of the printed product to keep the side of the printed product flush.
[0048] When printed materials are dumped onto the first conveyor 11, the spines of the printed materials may become skewed and deformed. In this embodiment, the alignment device 13 compresses the side surfaces of the printed materials to correct the deformation at the spines, keeping the sides of the printed materials flush and facilitating stacking. Furthermore, the alignment device 13 in this embodiment adjusts the position of the printed materials on the first conveyor 11, facilitating the stacking of multiple printed materials into a stack using the stacking device 14.
[0049] The stacking device 14 is located downstream of the first conveyor 11 and stacks the printed materials sequentially. After the printed materials are shaped and corrected by the alignment device 13, they continue along the first conveyor 11 and are stacked at the stacking device 14 to form a stack. The stack can be tilted directly or after further stacking and palletizing.
[0050] The stacking device 1 in this embodiment is suitable for thicker printed materials. During the tipping process, thicker printed materials can experience significant skew and deformation at the spine. In this embodiment, the alignment device 13 abuts and squeezes the sides of the printed materials, correcting their shape to maintain a roughly rectangular parallelepiped shape. It also adjusts the position of the printed materials on the first conveyor 11, for example, aligning the printed materials with the stacking device 14. The stacking device 1 in this embodiment can achieve fully or semi-automatic stacking of printed materials, reducing labor intensity and costs while improving work efficiency.
[0051] According to a preferred embodiment of the present invention, Figure 2 As shown, the alignment device 13 includes two parallel clamping plates 131 and a driver 132. The clamping plates 131 are arranged parallel to the direction of movement of the first conveyor 11 and are configured to move relative to each other. For example, the two clamping plates 131 can move closer to or farther from each other, or one clamping plate 131 can remain fixed while the other clamping plate 131 moves closer to or farther from the fixed clamping plate 131. The two clamping plates 131 can abut and press against the sides of the printed matter to correct skew deformation of the printed matter's spine.
[0052] Furthermore, in some embodiments, the two clamping plates 131 are configured to press against the spine and fore edge of a printed product. The fore edge refers to the side of a printed product opposite the spine and indicates the direction in which the printed product is opened. Preferably, the opposing surfaces of the two clamping plates 131 are flat, and they abut and press against the spine and fore edge of the printed product, reducing pressure on the printed product and preventing damage. Furthermore, the clamping plates 131 further adjust the shape of the printed product, maintaining alignment between the spine and fore edge.
[0053] Preferably, the shape and size of the splint 131 are larger than the area of the spine and the book edge of the printed matter. During the process of the splint 131 correcting the skew deformation of the spine, the printed matter continues to move along the first conveying device 11, and the splint 131 covers the spine and the book edge. The first conveying device 11 does not need to stop or slow down, which is conducive to improving work efficiency.
[0054] The driver 132 is in a transmission connection with at least one of the two clamping plates 131 and drives the clamping plates 131 to move closer to or farther from each other. In a preferred embodiment of the present invention, the driver 132 drives the two clamping plates 131 to move in the plane of the first conveyor 11 and perpendicular to the movement direction of the first conveyor 11 to change the position of the printed matter on the first conveyor 11. For example Figure 1 As shown in FIG, the first conveying device 11 moves from right to left, and the driver 132 drives the two clamping plates 131 to move in the Figure 1The printed matter moves in the up and down directions, and the position of the printed matter on the first conveying device 11 is changed under the clamping action of the two clamping plates 131.
[0055] In a preferred embodiment of the present invention, two clamping plates 131, driven by a driver 132, strike the spine and edge of a printed product. Furthermore, after striking the spine and edge of a printed product, the two clamping plates 131 separate from the spine and edge of the printed product. In this embodiment, the clamping plates 131 act on the spine and edge of the printed product for a relatively short period of time, which has a minimal impact on the operating efficiency of the first conveyor device 11. This eliminates the need to stop or slow down the first conveyor device 11, reduces the precision required for the alignment between the first conveyor device 11 and the alignment device 13, and reduces the production cost and control difficulty of the stacking apparatus 1.
[0056] like Figure 3 As shown, according to a preferred embodiment of the present invention, the horizontal height of the stacking device 14 is the horizontal height of the first conveying device 11. After the printed matter moves along the first conveying device 11 to the end of the first conveying device 11, it is transferred to the stacking device 14. For example, it falls on the stacking device 14 under the action of gravity, and the printed matter is stacked on the stacking device 14 from bottom to top.
[0057] Preferably, the stacking device 14 includes a limiting structure that can adjust the position of the printed products when they are transferred to the stacking device 14 so that the multiple printed products are aligned in the vertical direction. Specifically, the limiting structure can include a push rod that is controlled to abut against the edge of the printed products to push the printed products to align in the vertical direction.
[0058] In a preferred embodiment of the present invention, Figure 3 As shown, the stacking device 14 includes a bottom plate 141 and a partition 142. The partition 142 is located between the bottom plate 141 and the first conveying device 11, and the partition 142 is movable relative to the bottom plate 141, for example, the partition 142 is retractable or flippable relative to the bottom plate 141.
[0059] When the printed product moves along the first conveyor 11 to the end of the first conveyor 11, the printed product is transferred from the first conveyor 11 to the partition 142. The partition 142 moves relative to the bottom plate 141 to transfer the printed product to the bottom plate 141. Further, the partition 142 is reset to receive the next printed product. In this embodiment, the printed product can be positioned and positioned using the partition 142 to prevent rotation or angular displacement during transfer from the first conveyor 11 to the stacking device 14. Preferably, the partition 142 is positioned close to the first conveyor 11 to prevent the printed product from flipping. When the printed product is held horizontally on the partition 142, the partition 142 moves relative to the bottom plate 141, allowing the printed product to be transferred horizontally to the bottom plate 141 or the previous printed product. Furthermore, a pressure sensor is provided on the partition 142 to detect the posture of the printed matter on the partition 142. When the printed matter is in a horizontal posture, the partition 142 is controlled to move relative to the base plate 141 so that the printed matter is transferred to the base plate 141 or the previous printed matter.
[0060] Specifically, in some embodiments, the partitions 142 are retractable relative to the base plate 141. For example, the stacking device 14 includes two opposing partitions 142 that can retract in opposite directions to transfer the printed product to the base plate 141 or the previous printed product. In other embodiments, the partitions 142 are reversible relative to the base plate 141. For example, the stacking device 14 includes two opposing partitions 142 that can flip in opposite directions relative to the base plate 141, such as clockwise and counterclockwise, respectively. The gravity of the printed product can be used as the driving force for the partitions 142 to flip, which helps simplify the structure and reduce the cost of the stacking device 1. When the printed product is in a horizontal position, the partitions 142 are controlled to flip relative to the base plate 141.
[0061] According to a preferred embodiment of the present invention, the number of printed products in the stacking device 14 can be pre-set, for example, based on the thickness of the printed products and the distance between the stacking device 14 and the first conveying device 11. Furthermore, the distance between the stacking device 14 and the first conveying device 11 is adjustable to accommodate printed products of different thicknesses.
[0062] like Figure 1 As shown, in a preferred embodiment of the present invention, the stacking device 1 further includes a second conveyor 15. The second conveyor 15 can receive the stacked printed products from the stacking device 14 and drive the printed products. For example, the second conveyor 15 is disposed on the side of the stacking device 14 and can drive the stacked printed products to the next processing station, or drive the stacked printed products to the loading platform for mechanical or manual tilting.
[0063] Preferably, in this embodiment, the first conveyor device 11 comprises a conveyor roller, and the second conveyor device 15 comprises a conveyor belt. When printed materials move on the conveyor rollers, the contact surface between the bottom surface of the printed materials and the conveyor rollers is small, and the conveyor rollers can be configured to be relatively smooth. When the alignment device is used to correct the shape of the printed materials and adjust their position, the friction between the conveyor rollers and the printed materials is reduced, which helps protect the printed materials and allows for quick position adjustment, improving work efficiency. The contact surface between the conveyor belt and the printed materials is large, resulting in greater friction. This allows printed materials stacked one on top of the other to remain stationary relative to the conveyor belt while moving with it.
[0064] Finally, it should be noted that the above description is merely an embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
