Description

Technical Field

[0001] The utility model relates to the technical field of packaging machinery, in particular to a lid separating mechanism for cup lids. Background Art

[0002] In the automated packaging production process, medicine cups that have been filled with medicine need to be sealed with cup lids. Currently, the commonly used lid separation mechanism uses a reciprocating drive to drive a mechanical gripper or suction cup arm to move back and forth along the cup lid storage, and then remove the cup lids from the cup lid storage one by one to seal the medicine cup. However, the above method still has the following technical problems in actual use:

[0003] When the cup lids in the cup lid storage are exhausted, the entire mechanism has to be paused and restarted after the staff replenishes the cup lids in the cup lid storage. This results in poor sustainability of the entire cap separation mechanism during operation and low cap separation efficiency. Utility Model Content

[0027] like Figure 1 As shown, the utility model provides a lid separating mechanism for cup lids, comprising a vertical lid-lifting device 1 and a continuous lid-feeding device 2;

[0028] The continuous cap feeding device includes a plurality of tubular racks 22 arranged on a graduated plate 21. The inner cavity of the tubular racks 22 is used to place a plurality of stacked cup caps. A vertical through slot 23 corresponding to the cap-carrying plate 11 of the vertical cap-lifting device 1 is constructed on the side wall of the tubular racks 22 along the axial direction. The cap-carrying plate 11 is used to push the stacked cup caps upward at the bottom. The driving assembly of the vertical cap-lifting device 1 is used to drive the cap-carrying plate 11 to pass through the graduated plate 21 and enter and exit the tubular racks 22 through the vertical through slot 23.

[0029] When it is necessary to separate the covers, the indexing disc 21 drives one of the tubular racks 22 to move to the top of the cover carrier 11. The driving component drives the cover carrier 11 to enter the tubular rack 22 from the bottom of the tubular rack 22 after passing through the indexing disc 21, and move upward along the direction of the vertical through groove 23, and then push the stacked cup lids upward from the bottom in the inner cavity of the tubular rack 22. When the top cup lid moves up to the preset height point, the suction cup hand for separating the covers sucks the top cup lid away. In the process of the suction cup hand reciprocating the cup lids, the cover carrier 11 continues to move upward so that the subsequent cup lids move to the preset height points in turn. When the cup lids above the cover carrier 11 are consumed, the driving component drives the cover carrier 11 to The tubular rack 22 descends along the vertical through slot 23 until it passes through the dividing plate 21 and moves below the plane of the dividing plate 21. At this time, the dividing plate 21 rotates again to move the other tubular rack 22 to the top of the cover carrier 11, and repeats the above-mentioned cover separation process. In this process, when the cup lids in one of the tubular racks 22 are consumed, the dividing plate 21 can be rotated to move the other tubular racks 22 loaded with cup lids to the top of the cover carrier 11. In this process, the empty tubular rack 22 moves away from the cover carrier 11 as the dividing plate 21 rotates. The staff can replenish the empty tubular racks 22 with cup lids, thereby ensuring the continuity of the cover separation and greatly improving the work efficiency of the cover separation.

[0030] like Figure 3 As shown, specifically, a limiting slot 211 is constructed on the index plate 21 below the tubular frame 22. The width of the limiting slot 211 at its widest point is also smaller than the width of the tubular frame 22 (i.e., smaller than the width of the cup cover), thereby limiting the cup cover so that the cup cover will not fall off from the bottom of the tubular frame 22 under the action of its own weight after being loaded from the top of the tubular frame 22.

[0031] The narrowest width of the limiting slot 211 is greater than the width of the carrier cover 11 , thereby allowing the carrier cover 11 to enter and exit the tubular frame 22 via the indexing plate 21 .

[0032] like Figure 2 As shown, specifically, the driving assembly includes a driving motor 12, a driving wheel 13, a driven wheel 14, and a synchronous belt 15. In this embodiment, the driving wheel 13 and the driven wheel 14 are both synchronous pulleys that can be meshed with the inner ring of the synchronous belt 15;

[0033] The driving bracket 16 is arranged upright in the same direction as the tubular frame 22, and the driving motor 12 is horizontally installed on the motor support seat. The output end of the driving motor 12 passes through the driving bracket 16 and is coaxially fixedly connected to the driving wheel 13. The driven wheel 14 is installed on the other end side of the driving bracket 16 through a bearing, that is, the driving wheel 13 and the driven wheel 14 are respectively located at the top and bottom ends of the driving bracket 16, thereby providing height movement for the carrier cover 11. The driven wheel 14 is connected to the driving wheel 13 through a synchronous belt 15, and the moving platform 17 is clamped on the synchronous belt 15. The carrier cover 11 is fixedly connected to the moving platform 17; the synchronous belt 15 is driven by the driving motor 12 to rotate, thereby driving the moving platform 17 on the synchronous belt 15 to move vertically along the driving bracket 16, thereby realizing the lifting and lowering of the carrier cover 11.

[0034] like Figure 2 As shown, further, since the synchronous belt 15 has the characteristic of elastic deformation, if the cover plate 11 encounters a large resistance during the lifting process of the synchronous belt 15, the cover plate 11 is prone to deflection and shaking, thereby affecting the lifting of the cup cover. Therefore, in this embodiment, a linear slide rail 18 is further provided to guide the lifting of the cover plate 11.

[0035] Specifically, a linear slide 18 is also uprightly installed on the driving bracket 16. In this embodiment, in order to avoid spatial conflict between the linear slide 18 and the driving component, the linear slide 18 is arranged on the back side of the driving bracket 16, and the moving platform 17 is fixedly connected to the moving seat 181 on the linear slide 18; then, under the limiting action of the moving seat 181, the moving platform 17 will not tilt or shake left and right, and can only perform lifting and lowering movements when driven by the synchronous belt 15.

[0036] like Figure 1 As shown, specifically, the carrier cover plate 11 is an L-shaped structure, and the top of the carrier cover plate 11 is connected to the movable platform 17 by a fixing screw; when the movable platform 17 moves to the downward limit position (the movable platform 17 contacts the driving wheel 13 and cannot move downward), the horizontal portion of the carrier cover plate 11 is located below the plane where the driving wheel 13 is located, so that the carrier cover plate 11 can have a larger downward distance within the limited travel space, so that the carrier cover plate 11 passes through the dividing plate 21 and is separated from the tubular frame 22.

[0037] like Figure 3 As shown, a feeding sensor 31 is also installed on the bottom side of the dividing plate 21. The feeding sensor 31 is used to determine whether there is a cup lid in the tubular rack 22 located above it. When the feeding sensor 31 detects that there is no cup lid in the tubular rack 22 above it, a warning is issued to remind the staff to replenish the cup lid.

[0038] A support rod is installed on the central non-rotating area of the dividing plate 21, and a residual material sensor 32 is installed on the support rod. The residual material sensor 32 is used to determine whether there is a cup cover on the cover carrier plate 11. When a cup cover is detected, the drive motor 12 drives the synchronous belt 15 to drive the cover carrier plate 11 to rise, and feed the reciprocating suction cup hand. When no cup cover is detected, the drive motor 12 drives the synchronous belt 15 to drive the cover carrier plate 11 downward and out of the tubular frame 22 until it passes through the dividing plate 21 and moves below the plane where the dividing plate 21 is located. At this time, the dividing plate 21 rotates again to move another tubular frame 22 to the top of the cover carrier plate 11, and repeat the above-mentioned cover separation process.

[0039] The working principle and working process of this utility model are as follows:

[0040] When it is necessary to separate the covers, the indexing disc 21 drives one of the tubular racks 22 to move to the top of the cover carrier 11. The driving motor 12 drives the synchronous belt 15 to drive the cover carrier 11. After passing through the indexing disc 21, it enters the tubular rack 22 from the bottom of the tubular rack 22 and moves upward along the direction of the vertical through groove 23, and then pushes the stacked cup lids from the bottom in the inner cavity of the tubular rack 22 to push it upward. When the top cup lid moves up to the preset height point, the suction cup hand for separating the covers sucks the top cup lid away. In the process of the suction cup hand reciprocating the cup lids, the cover carrier 11 keeps moving up so that the subsequent cup lids move to the preset height points in turn. When the cup lids above the cover carrier 11 are After the cup lids are consumed, the driving assembly drives the cover carrier plate 11 downward along the vertical through slot 23 in the tubular rack 22 until it passes through the dividing plate 21 and moves below the plane where the dividing plate 21 is located. At this time, the dividing plate 21 rotates again to move another tubular rack 22 to the top of the cover carrier plate 11, and repeat the above-mentioned cover separation process; in this process, when the cup lids in one of the tubular racks 22 are consumed, the dividing plate 21 can be rotated to move the other tubular racks 22 loaded with cup lids to the top of the cover carrier plate 11. In this process, the empty tubular racks 22 move away from the cover carrier plate 11 as the dividing plate 21 rotates, and the staff can replenish the empty tubular racks 22 with cup lids.

[0041] The above embodiments of the present invention are described in detail. However, the above contents are only preferred embodiments of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of this patent.
