Description

Technical Field

[0001] This utility model relates to the field of gripping technology, specifically to a device for sucking up cigarette label paper. Background Technology

[0002] Cigarette pack label paper is an important raw and auxiliary material for cigarette packaging. In the production and operation of FOCKE-FX and ZB48 series high-speed packaging equipment, it is usually supplied in a layered stacking method. First, 500 labels are stacked together and wrapped with kraft paper to form a separate stack. Then, each stack of labels is stacked in layers, rows and columns on a pallet, with partitions separating the layers. When each layer of labels is used up, the partitions must be removed and recycled to the partition storage before the next layer of labels can be retrieved.

[0003] The FOCKE-FX and ZB48 series high-speed packaging machines operate at speeds up to 700 packs per minute, consuming an average of one layer of label stacks every half hour. Currently, the label stacks are gripped automatically using a negative pressure suction nozzle at the end of a robotic arm, following a pre-set depalletizing program. After gripping one layer, the same negative pressure suction nozzle is used to pick up the partitions. However, due to the large size of the partitions, the suction nozzle can only pick up a specific area, leading to unstable partition gripping, easy drop and disruption of the label stacks below, or triggering a shutdown procedure. To address this issue, this invention provides a label stack suction device for cigarettes. Utility Model Content

[0025] refer to Figure 1-4 This utility model provides a cigarette label paper stub suction device, including a support plate 1. The bottom surface of the support plate 1 is provided with a rotating mechanism, and a suction cup seat 13 is connected to the rotating mechanism so that the suction cup seat 13 can rotate, thereby enabling the reversing operation of the gripped label paper stub. The suction cup seat 13 has a cavity structure and multiple paper stub suction cups 19 are arranged in an array on the bottom surface of the suction cup seat 13. Preferably, the paper stub suction cups 19 are connected to the cavity of the suction cup seat 13. The paper stub suction cups 19 are in 3 groups, with 3 in each group.

[0026] Specifically, the rotating mechanism includes a bottom cover 12 and a servo motor 14. The servo motor 14 is disposed within the bottom cover 12, and its output end passes through the bottom surface of the bottom cover 12 and is connected to the suction cup seat 13. The bottom cover 12 is mounted on the bottom surface of the support plate 1 with screws. Notably, the rotation range of the servo motor 14 is set to 0-180° to prevent excessive rotation from causing the wiring conduit to become entangled. Furthermore, in some embodiments, a rotary cylinder may also be used as the rotating mechanism.

[0027] Telescopic rods 3 are slidably arranged on both sides of the support plate 1. The telescopic rods 3 are located on the same straight line. An installation plate 8 is vertically arranged at the end of the telescopic rod 3. A rotary cylinder 9 is fixedly arranged on the installation plate 8. Preferably, the rotation angle of the rotary cylinder 9 is 0-90°. An auxiliary rod 10 is arranged on the rotation surface of the rotary cylinder 9. An air extraction channel 10a is arranged inside the auxiliary rod 10. A partition suction cup 11 is arranged at the bottom end of the auxiliary rod 10. The air extraction channel 10a is connected to the partition suction cup 11, so that a negative pressure is formed at the partition suction cup 11. When the auxiliary rod 10 is in a vertical state, the bottom surfaces of the partition suction cup 11 and the paper stack suction cup 19 are located in the same horizontal plane, so that the partition suction cup 11 and the paper stack suction cup 19 can contact the partition at the same time.

[0028] The support plate 1 is also equipped with a drive mechanism for synchronously extending and retracting the two telescopic rods 3.

[0029] In order to allow the telescopic rod 3 to slide to both sides, square tubes 2 are provided on both sides of the support plate 1. A slot 2a is provided on the upper surface of the square tube 2 along the length direction. The telescopic rod 3 passes through the square tube 2 and a slider 5 is provided on the upper surface of the telescopic rod 3. The slider 5 is located in the slot 2a and is connected to the drive mechanism.

[0030] Specifically, the driving mechanism includes a cylinder 6, a rod connector 7, and a connecting rod 4. The cylinder 6 is mounted on the support plate 1, and a rod connector 7 is provided at the extension end of the cylinder 6. Two connecting rods 4 are rotatably mounted on the rod connector 7. The two connecting rods 4 are arranged in a "V" shape. The other end of the connecting rod 4 is rotatably connected to the slider 5. When the cylinder 6 is extended, the included angle between the two connecting rods 4 increases, thereby pushing the telescopic rod 3 to extend outward.

[0031] The upper surface of the support plate 1 is connected to the connecting plate 18 via a short column 17, so that the device can be connected to the robotic arm. A strip-shaped notch 1a is provided on the support plate 1 to accommodate the auxiliary rod 10. The strip-shaped notch 1a is located on the side close to the square tube 2. When the auxiliary rod 10 is retracted, the auxiliary rod 10 retracts into the strip-shaped notch 1a.

[0032] Both the suction cup base 13 and the auxiliary rod 10 are provided with air inlet pipes 20. The air inlet pipe 20 on the auxiliary rod 10 is connected to the suction channel 10a. The bottom surface of the support plate 1 is provided with a suction connector 16. The air inlet pipe 20 is connected to the suction connector 16 through a pipe. The suction connector 16 is provided with at least four ports, which are respectively connected to the negative pressure pump, the air inlet pipe 20 on the suction cup base 13, and the air inlet pipes 20 on the two auxiliary rods 10 through pipes.

[0033] In addition, the bottom surface of the support plate 1 is provided with two RGB color sensors 15. The partition is identified by the RGB color sensors 15. The configuration must be such that the cylinder 6 and the rotary cylinder 9 are started only when both RGB color sensors 15 detect the partition.

[0034] The working principle of this utility model is that when gripping the label paper stacks, under the action of negative pressure, the label paper stacks are simply picked up by the paper stack suction cup 19; when the label paper stacks of this layer are completely gripped, the partition is completely exposed, the cylinder 6 and the rotary cylinder 9 are energized, causing the telescopic rod 3 and the auxiliary rod 10 to extend. The auxiliary rod 10 is perpendicular to the support plate 1. At this time, the partition suction cup 11 and the paper stack suction cup 19 come into contact with the partition and are picked up by the partition under the action of negative pressure, which improves the stability of the picking process.

[0035] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that those skilled in the art can devise many other modifications and implementations that fall within the scope and spirit of the principles disclosed herein. More specifically, various modifications and improvements can be made to the components or layout of the subject matter arrangement within the scope of the disclosure, drawings, and claims. Besides modifications and improvements to the components or layout, other uses will be apparent to those skilled in the art.
