Description

Technical Field

[0001] The utility model belongs to the technical field of stacking material processing, and in particular relates to a stacking material conveying device, which is used for conveying stacked materials in a production link. Background Art

[0002] Existing box-making equipment has limited storage capacity for paper stock silos, designed to load paper stock approximately every half hour. This requires workers to spend approximately half an hour near the silo, organizing the stacks and waiting for the right moment to load them into the silo. This solution considers the convenience and safety of manual loading, as well as the coordination of all aspects of the production line. However, technological advancement requires further reduction of manual involvement on the production line to free up labor. Therefore, the inventors proposed developing a device at the front end of the equipment to replace manual labor in continuously feeding paper stock to downstream production lines. Summary of the Invention

[0018] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0019] The following embodiments are all based on paper materials commonly found in packaging box production lines. Similar industries all have stacks of such sheet materials and are therefore applicable.

[0020] Example 1

[0021] Figure 1The diagram shows the stacking of materials, most commonly paper, with multiple layers stacked to form a single pile, approximately several dozen centimeters high. In existing carton processing equipment, a stack is typically stored in a hopper. A robotic suction cup then removes the material layer by layer from above or below, taking individual sheets to a subsequent station for gluing or forming. Typically, several stacks of material are stacked alongside the equipment on the production line. Once the stack in the hopper is exhausted, they are manually carried into the hopper for replenishment. The height of the stack is H, and the width is W. Using the existing conveyor line push block method would disperse the stack. Raising the push block would create excessive clearance in the mechanical structure, making it difficult to interface with the original equipment.

[0022] Figure 2 The structure of a stacking material conveying device is shown, including a frame 1 for supporting various structural components. A platform 2 is provided on the frame 1, and a stack of materials S is placed on the platform 2. The stack of materials is configured to slide in the front-to-back direction on the platform. A first material shifting assembly 3 includes a first material shifting portion 31 protruding above the platform 2. The first material shifting portion 31 corresponds to the lower half of the stack of materials S and can move in the front-to-back direction along the platform 2. A second material shifting assembly 4 includes a second material shifting portion 41 corresponding to the upper half of the stack of materials S. The second material shifting portion 41 can also move in the front-to-back direction along the platform 2. A driving assembly 5 is used to drive the first and second material shifting assemblies (3, 4) to move synchronously in the front-to-back direction.

[0023] In this solution, the two material-dispensing parts are spliced into a vertical plane, parallel to the height plane of the entire stack, and synchronously push the entire stack forward, so that the force on the stack is more even, and the entire stack moves forward until it enters the hopper of the equipment, which can reduce the frequency of manual loading. The manual loading location is transferred from the hopper inside the equipment to the conveyor device, which is also more convenient. It should be noted that there can also be two drive assemblies 5, which can independently drive the first and second material-dispensing assemblies to achieve the purpose of synchronous movement in the forward and backward directions.

[0024] Preferably, Figure 3 In this embodiment, the first material-pusher 31 extends and retracts vertically in the height direction H, returning to its original position below the platform. The second material-pusher 41 extends and retracts to either side in the width direction W, returning to its original position laterally from the platform. This completes the process of pushing the current stack forward before moving on to the next cycle, pushing the next stack forward. This design prevents the conveyor from being too high.

[0025] like Figure 34 and 5. The extension and retraction of the first material-digging component 3 in the height direction H and the extension and retraction of the second material-digging component 4 in the width direction W of the present embodiment are implemented as follows: the first material-digging component also includes a first sliding component 32 arranged in the height direction H and an elastic member 33 cooperating with the first sliding component. A roller 45 is provided below the first material-digging part 31. One end of the elastic member 33 is connected to other parts of the first material-digging part, and the other end is fixedly connected. At this time, no drive for separately driving the first material-digging component to rise is provided in the height direction; the second material-digging component 4 includes a second sliding component 42 arranged in the width direction W of the stack; it also includes a connecting plate 43, one side of which is connected to the second sliding component 42, and the other side is connected to the second material-digging part 41 through a connecting rod 46. The second material-digging part 41 extends from the side of the stack S into the corresponding space of the upper half of the stack. The connecting plate 43 is also provided with an inclined portion 44 cooperating with the roller 45 and a driver 47. The driver 47 is connected to the connecting plate 43. The driver 47 cooperates with the second sliding component 42 to drive the connecting plate 43 to move in the width direction W.

[0026] The working principle of this design is: the driver 47 drives the connecting plate 43 to slide to the left along the width direction, and the second material-pickup part 41 then extends to the left into the back space of the stack S, and the inclined part 44 lifts the roller 45, driving the first material-pickup part 31 to rise and extend from the bottom of the platform into the back space of the stack S, thereby realizing the linkage between the first material-pickup component and the second material-pickup component, that is, only one driver 47 is needed to complete the extension and retraction of the first material-pickup component 3 in the height direction H and the extension and retraction of the second material-pickup component 4 in the width direction W.

[0027] Furthermore, in this solution, a plurality of first material diverting parts 31 and second material diverting parts 41 are provided, and the two first material diverting parts 31 and the second material diverting parts 41 on the same side of the stack correspond to each other one by one. The space between the four adjacent front and rear material diverting parts forms a cache space, and multiple stacks of paper materials are manually placed one by one in the cache space for cache. One stack of materials can be processed by the equipment for half an hour, and multiple stacks of materials can free up labor for more than several hours.

[0028] The platform 2 in this solution adopts two smooth strips arranged in parallel, and can also adopt two conveyor synchronous belts arranged in parallel.

[0029] In this solution, a fixed baffle is also provided on the side of the platform to facilitate manual patting and arranging the outline of the stacked materials when stacking them from the opposite side.

[0030] The driving component in this solution adopts a combination of linear drivers such as cylinders and guide pairs. The driver can be replaced by conventional technical means such as motor screws and electric push rods.

The second material shifting portion 41 can also move forward and backward along the platform 2.

[0033] It also includes a third sliding assembly (not shown in the figure) that drives the first material-digging part 31 to extend and retract along the height direction, and a fourth sliding assembly (not shown in the figure) that drives the second material-digging part 41 to extend and retract along the height direction.
