Description

Technical Field

[0001] This utility model relates to the field of cup lid packaging technology, and in particular to an automatic stacking device for cup lid production. Background Technology

[0002] In the food and beverage industry, thin and soft cup lids (such as disposable milk tea cup lids, yogurt cup lids, paper cup lids, etc.) are widely used due to their lightweight, low cost, and portability. These cup lids are mostly made of thin PP, PE, or paper, and are relatively thin. They are prone to irreversible deformation under external force. Currently, in the production and packaging of cup lids, the cup lids conveyed on the conveyor belt are usually stacked vertically and then packaged in subsequent packaging bags. However, because the side walls of the cup lids are extremely thin, they may be subjected to gravity during the stacking process, causing the bottom contact part of the cup lid to be compressed and deformed, which affects the production quality of the cup lids.

[0003] Based on the above situation, it is necessary to design an automatic stacking device for cup lid production to solve the above problems. Utility Model Content

[0004] This invention provides an automatic stacking device for cup lid production to solve the problems existing in the prior art.

[0005] The technical problem solved by this utility model is achieved by the following technical solution: An automatic stacking device for producing cup lids includes a supporting mechanism, a shifting mechanism, and a controller. The supporting mechanism supports vertically stacked cup lids and includes a support frame and a limiting ring disposed on the outside of the support frame and coaxially arranged with the support frame. The shifting mechanism includes a rotating component and a telescopic component connected to the rotating component. The movable end of the telescopic component is connected to an adsorption mechanism for adsorbing cup lids via a connecting column. The controller is configured to control the telescopic component to place a single cup lid onto the supporting mechanism, and then drive the telescopic component to move the adsorption mechanism upward by a preset distance to prevent subsequently placed cup lids from compressing the already stacked cup lids.

[0006] Preferably, a connecting ring is slidably connected to the connecting column, and a pressure sensor electrically connected to the controller is provided at the bottom of the connecting ring. When the pressure sensor abuts against the limiting ring and sends a trigger signal to the controller, the controller receives the trigger signal, determines that a single cup lid has been placed, and drives the telescopic component to move the adsorption mechanism upward.

[0007] Preferably, it also includes a turntable driven to rotate by a driving component, and the supporting mechanism is provided on the turntable and there are multiple sets of the supporting mechanism, which are equidistant from the circumference of the turntable's axis.

[0008] Preferably, the controller is further configured to have a preset counting threshold corresponding to the target stacking quantity. When the number of trigger signals sent by the pressure sensor by the controller reaches the counting threshold, the drive unit drives the turntable to rotate, moving the support mechanism of the stacked cup lid out of the lid placement station.

[0009] Preferably, the bottom end of the support member extends through the turntable and is slidably connected to the turntable.

[0010] Preferably, the telescopic component is a ball screw type electric telescopic rod, and its telescopic error is ≤0.1mm.

[0011] The beneficial effects of this utility model are: by allowing the supporting mechanism to contact the center area of ​​the cup lid, the cup lids are stacked vertically, avoiding the problem of deformation of the bottom edge part when stacked vertically. At the same time, after each cup lid is placed, the shifting mechanism is controlled to move upward gradually as the stacking thickness increases, avoiding the problem of excessive pressure on the cup lids already stacked below due to the weight of the cup lids and the downward movement, which would affect the production and packaging quality of the cup lids.

Detailed Implementation

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0016] Reference Figures 1-3As shown, an automatic stacking device for producing cup lids includes a support mechanism 1 for supporting vertically stacked cup lids. The support mechanism 1 includes a support frame 11 and a limiting ring 12 located outside the support frame 11 and coaxially arranged with it. It also includes a shifting mechanism and a controller 3. The shifting mechanism includes a rotating component 2 and a telescopic component 21 connected to the rotating component 2. The movable end of the telescopic component 21 is connected to an adsorption mechanism 23 for adsorbing the cup lids via a connecting post 22. The adsorption mechanism 23 can be a vacuum suction cup, connected to an external vacuum generator via an air pipe to generate negative pressure to adsorb the cup lids. Specifically, the rotating component 2 can be a motor or other driving device connected to the telescopic component 21 via a connecting rod. The telescopic component 21 drives the adsorption mechanism. After the produced cup lids are adsorbed from the conveyor belt, they are rotated to the support mechanism 1 by the rotating component 2. Then, the adsorption mechanism 23 is moved downward by the telescopic component 21, so that the cup lids are stacked on the support mechanism 1. The stacked cup lids are limited and supported by the limiting ring 12, wherein the inner diameter of the limiting ring 12 can be slightly larger than the outer diameter of the cup lid, so that the cup lids will not tip over when stacked on the support mechanism 1, and will be kept in a vertical stacked state to avoid deformation of the edge parts due to pressure. As the number of cup lids stacked increases, the stacking height also increases. Therefore, the controller 3 is configured to control the telescopic component 21 to place a single cup lid on the support mechanism 1, and then drive the telescopic component 21 to move the adsorption mechanism 23 upward by a preset distance to prevent the cup lids placed later from squeezing the already stacked cup lids.

[0017] Reference Figure 2 As shown, a connecting ring 4 is slidably connected to the connecting column 22. A pressure sensor 41 electrically connected to the controller 3 is provided at the bottom of the connecting ring 4. In the free state, the connecting ring 4 will fall to the bottom of the connecting column 22 under its own gravity. When the telescopic component 21 drives the connecting column 22 and the adsorption mechanism 23 to move downward to stack cup lids on the support mechanism 1, the connecting ring 4 first drives the pressure sensor 41 to contact the limiting ring 12, so that the pressure sensor 41 generates a pressure signal. After the controller 3 receives the signal, it determines that a cup lid has been stacked. At this time, the height of the stacked cup lids will increase synchronously by a height s1. The controller 3 will control the telescopic component 21 to reduce the distance of downward movement by a height s1 in the next telescopic action to avoid the telescopic component 21 from being at the same height each time it places a cup lid, which would cause excessive compression between the stacked cup lids and cause them to deform.

[0018] The system also includes a turntable 51 driven by a drive unit 5. Multiple sets of support mechanisms 1 are mounted on the turntable 51 and are equidistant from the axis of the turntable 51. The support mechanism 1 that moves to the lower end of the shifting mechanism is the lid placement station. The drive unit 5 can be a servo motor or other device. The controller 3 is also configured to preset a counting threshold corresponding to the target stacking quantity. For example, if the quantity placed each time is 50 cup lids, the counting threshold is set to 50. When the controller 3 accumulates the number of trigger signals sent by the pressure sensor 41 to reach the counting threshold, the drive unit 5 drives the turntable 51 to rotate, moving the support mechanism 1 that has stacked the cup lids out of the lid placement station. When other idle support mechanisms 1 move to the lid placement station below the shifting mechanism, they can perform cup lid support work. The support mechanism 1 that moves out of the lid placement station can then package the cup lids after quantitative stacking.

[0019] Reference Figure 1 As shown, further, in order to facilitate the removal and packaging of the cup lids on the support mechanism 1 after quantitative stacking, the bottom end of the support frame 11 passes through the turntable 51 and is slidably connected to the turntable 51. When removing the cup lids, the packaging bag can be placed on the outside of the limiting ring 12, and then the support frame 11 can be pushed upward from below the turntable 51 to make the stacked cup lids move upward and enter the packaging bag for packaging.

[0020] Furthermore, the telescopic component 21 is a ball screw type electric telescopic rod, and its telescopic error is ≤0.1mm. The telescopic component 21 is precisely controlled to move upward with the stacking height, ensuring that the upward movement each time matches the thickness of a single cup lid. This prevents the cup lid from squeezing the side wall of the lower cup lid due to insufficient upward movement, and also prevents the cup lid from falling off or being misaligned due to excessive upward movement.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
