Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a label paper picking mechanism. Background Technology

[0002] In the cigarette production and packaging process, stacked label papers need to be picked up one by one and placed on a conveyor. On the conveyor, the label papers are folded into a box-shaped structure through a folding process. Then, cigarettes or cigarette boxes are put into the box-shaped structure to complete the boxing operation. The process of picking up the label papers one by one is usually completed by a robot or a picking and sorting device. However, both the robot and the picking and sorting device have relatively complex structures. For example, utility model CN210338582U describes a trademark paper sorting and conveying device, including a mounting bracket, a frame, and an auxiliary support. The mounting bracket is located above the frame and is equipped with a horizontal moving delivery device. One end of the horizontal moving delivery device is equipped with a negative pressure trademark paper picking device. A grinding wheel mold is installed on the frame. The auxiliary support is located on one side of the frame and is equipped with a swing-type double-core shaft trademark stack bracket. A connecting platform is provided between the auxiliary support and the frame, and a trademark stack lifting device is installed on the connecting platform. The negative pressure trademark paper picking device corresponds vertically to the trademark stack lifting device. This device requires the cooperation of multiple components such as a lifting cylinder 111, a pushing cylinder 6, and a servo motor 201, making its structure and connection relatively complex and costly. On the other hand, the picking process requires multiple steps, such as starting the lifting cylinder 111, blowing compressed air into the interference block 17, and starting the pushing cylinder 6 to move the trademark paper, making the picking process cumbersome and inefficient. In response, this utility model provides a trademark paper picking mechanism. Utility Model Content

[0029] Please see Figure 1-3 As shown, this utility model provides a label paper picking mechanism, including a sliding seat 8, a label paper placement rack 13, a drive unit, and a picking drum 12. The sliding seat 8 is slidably disposed between the side walls 1 of the housing. The sliding seat 8 is provided with a shaft hole 81, and a hollow rotating shaft 11 is inserted and connected through the shaft hole 81. The sliding direction of the hollow rotating shaft 11 is opposite to that of the sliding seat 8.

[0030] Specifically, two guide rods 2 are fixedly installed between the side walls 1 of the housing, and a guide rod sleeve 82 is fixedly installed on the sliding seat 8. The guide rod sleeve 82 passes through the guide rods 2, thereby achieving stable operation of the sliding seat 8. More specifically, the guide rods 2 are hollow tubes, and one end of the guide rod 2 extends through the side wall 1 of the housing. An oil supply main pipe can be connected to the through end of the two guide rods 2, so that lubricating oil is delivered to the guide rods 2 through the oil supply main pipe. The guide rods 2 are provided with overflow holes 21. The lubricating oil delivered to the guide rods 2 overflows through the overflow holes 21 and is dispersed to the circumference of the guide rods 2 by the reciprocating motion of the guide rod sleeve 82. Figure 7 As shown, the inner wall of the guide rod sleeve 82 is provided with multiple oil grooves 821, which can store a small amount of lubricating oil for use during the sliding process. This ensures the lubrication of the sliding seat 8 during its movement.

[0031] A gear 7 and a connector assembly 16 are provided at one end of the hollow shaft 11. The connector assembly 16 is connected to the end of the hollow shaft 11 and is used to connect to a negative pressure pump via an air tube. (See reference...) Figure 5 As shown, specifically, the connector assembly 16 includes a bearing 162 and a nozzle 161. The inner ring of the bearing 162 is located at the end of the hollow rotating shaft 11, and the nozzle 161 is located on the outer ring of the bearing 162. The nozzle 161 is used to connect to the aforementioned air tube. This structure ensures that the rotation of the hollow rotating shaft 11 and the nozzle 161 do not affect each other, thereby preventing the air tube from twisting. A pickup drum 12 is located at the other end of the hollow rotating shaft 11. A suction nozzle 17 is located on the circumference of the pickup drum 12. The suction nozzle 17 is connected to the hollow rotating shaft 11 through a suction tube 18. Preferably, there are 2-3 suction nozzles 17, and the ends of the suction nozzles 17 protrude from the outer circumference of the pickup drum 12, with a protruding length of 1-3 mm. During pickup, a negative pressure pump draws air to create a negative pressure at the suction nozzle 17, allowing the suction nozzle 17 to pick up the bottom layer of packaging paper.

[0032] refer to Figure 4As shown, a front support 14 is provided on the front side of the sliding seat 8, and a support wheel 15 is rotatably mounted on the front support 14. The support wheel 15 is located outside the sliding seat 8. During the movement of the sliding seat 8, the support wheel 15 supports the front side of the trademark paper. A rear support 9 is provided on the rear side of the sliding seat 8, and a support plate 10 is provided on the rear support 9. The support plate 10 is also located outside the sliding seat 8. Preferably, the front end of the support plate 10 is an arc surface or a slope surface. During the movement of the sliding seat 8, the support plate 10 supports the rear side of the trademark paper and isolates the upper stack of trademark paper and the trademark paper being picked up. A rack 4 is also slidably mounted between the side walls 1 of the housing. The rack 4 meshes with the gear 7 and is connected to the sliding seat 8 through a side plate 6. A drive unit for driving the rack 4 to move linearly is also fixedly mounted on one side of the side wall 1 of the housing. When the drive unit works, it drives the rack 4 to move linearly, causing the sliding seat 8 to move linearly as well. At the same time, the rotation of the gear 7 drives the rotation of the picking drum 12, thereby peeling off the bottom layer of trademark paper.

[0033] To ensure the linear sliding of the square rod 3, a square rod 3 is fixedly installed between the side walls 1 of the housing, and a through hole is provided on the rack 4 along the length direction and the through hole passes through the square rod 3.

[0034] In some embodiments, the drive unit is a cylinder 5, and a push-out part 41 is provided on the rack 4. The push-out end of the cylinder 5 is connected to the push-out part 41, and the push-out part 41 is connected to the side plate 6 by screws. It is worth noting that the drive unit is not limited to a cylinder, but can also be a motor and a reciprocating lead screw. In addition, a motor and a connecting rod drive can also be used.

[0035] To achieve position adjustment of the support plate 10, thereby enabling the adjustment of the support plate 10's functional position according to different lengths of trademark paper and thus supporting and isolating the trademark, the sliding seat 8 is provided with sliding guide rails 83, and the rear bracket 9 is slidably disposed between the sliding guide rails 83. Preferably, there are two sets of sliding guide rails 83, and the rear bracket 9 is "H"-shaped with its two bottom ends slidably disposed between the sliding guide rails 83. The sliding seat 8 is also provided with two screw supports 84, and an adjusting screw 85 is rotatably disposed between the screw supports 84. The rear bracket 9 is provided with an internal threaded hole, and the internal threaded hole is threadedly connected to the adjusting screw 85, so that the position of the rear bracket 9 can be adjusted by rotating the adjusting screw 85.

[0036] refer to Figure 6As shown, in order to accommodate trademark papers of different lengths and sizes, the trademark paper holder 13 includes a fixed frame 131 and a movable frame 133. Both the fixed frame 131 and the movable frame 133 are formed by horizontally and vertically connecting rods. The rods are square steel bars welded together horizontally and vertically. The fixed frame 131 is fixedly installed and can be fixed to the outside of the side wall 1 of the machine housing. It is worth noting that the area enclosed by the fixed frame 131 and the movable frame 133 has no bottom surface. When the trademark paper is placed in this enclosed area, it is supported by the pick-up drum 12 and the support wheels 15. The crossbar of the fixed frame 131 is a hollow structure and has a strip-shaped through hole 132 on its side wall. To enable the adjustment of the movable frame 133, the crossbar of the movable frame 133 passes through the crossbar of the fixed frame 131, and a stud 134 is provided on the crossbar of the movable frame 133. The stud 134 is located in the strip-shaped through hole 132 and a clamping nut 135 is threaded onto the stud 134. The movable frame 133 is pulled out according to the length of the label paper so that the movable frame 133 and the fixed frame 131 can just surround the label paper. The position of the movable frame 133 is fixed by tightening the clamping nut 135.

[0037] The working process of this utility model is as follows: stacked trademark papers are placed in the trademark paper placement rack 13, and the movable rack 133 is adjusted so that it can just surround the trademark papers. At this time, the stack of trademark papers just falls on the pick-up drum 12 and the support wheel 15 for support. The drive unit is started, and the rack 4 and the sliding seat 8 are pushed out in a straight line together. Since the rack 4 and the gear 7 mesh, the hollow rotating shaft 11 and the pick-up drum 12 are rotated together through the gear. The suction nozzle 17 in the pick-up drum 12 is in a negative pressure state through the negative pressure pump, thereby adsorbing the bottom layer of trademark papers. Due to the rotation of the pick-up drum 12, the adsorbed trademark papers are adsorbed around the circumference of the pick-up drum 12, thereby separating the bottom layer of trademark papers from the top layer of trademark papers. During the movement of the sliding seat 8, the support plate 10 moves forward to support the back of the trademark papers and isolate the bottom layer of trademark papers. After the sliding seat 8 moves to the other end, the negative pressure of the suction nozzle 17 disappears, and the trademark papers are released and fall onto the conveying device below.

[0038] 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.
