DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] Example 1

[0024] A glass wine bottle labeling mechanism, comprising a conveyor belt 1, a label header device 2, a labeling device 3, a partition plate 4 and a support frame 5;

[0025] The conveyor belt 1, header device 2, labeling device 3, and partition plate 4 are installed on the support frame 5; the header device 2 includes a reeling roller 6, a buffer roller 7, a guide roller 8, a partition plate 4, a driving roller 10 and a paper receiving roller 11, and the paper receiving roller 11 is arranged at the left end of the header device 2, the guide roller 8 has a front end guide roller 8 and a rear end guide roller 8, the front end guide roller 8 includes roller one and roller two, the buffer roller 7, roller one, and roller two form a triangular structure, the rear end guide roller 8 includes roller three, roller four and roller five, the end of roller five is located at the entrance end of the partition plate 4, roller five is located on the inner side of the partition plate 4 and has a certain gap from the partition plate 4, and the label forms an acute angle structure with roller five and the partition plate 4.

[0026] In order to avoid the label tape from loosening during operation and the label from being pasted inaccurately, a guide roller 8 and a label detection device are added between the unwinding roller 6, the driving roller 10 and the paper receiving roller 11. This ensures that the label tape always has a certain tension during the labeling process and ensures that the label is accurately positioned, completely and correctly pasted.

[0027] The buffer roller 7 is a friction brake mechanism composed of a lever mechanism. During the labeling process, due to the tension of the label tape, the buffer roller 7 will swing at a certain angle, thereby driving the rotation of the label roll. After a label is output, the motor will stop running, the traction force of the label tape will decrease, and the buffer roller 7 will return to its original position under the influence of the spring. At the moment of rebounding, the unwinding roller 6 has an anti-rotation mechanism to prevent the label roll from rotating and causing the label tape to loosen.

[0028] Unwinding roller 6: used to place roll labels, usually equipped with a brake device with adjustable friction, the purpose is to control the speed and tension of the roll, and maintain the smooth transportation of the label. 2 Buffer roller 7: can swing back and forth, the purpose is to absorb the tension of the roll material when the device is started, keep the material in contact with other rollers, and prevent the material from breaking. 3 Guide roller 8: plays a role in guiding and positioning the roll material. 4 Driving roller 10: composed of a group of friction wheels. Usually one is a rubber roller and the other is a metal roller, and the base paper passes on the roller. The function is to drive the roll material to achieve normal labeling. 5 Paper collection roller 11: an active wheel with a friction device, the function is to recycle the roll paper after labeling. 6 Partition plate 4: peel off the label and the base paper, so that the base paper is separated from the wine bottle to complete the labeling work.

[0029] The mounting device is arranged at the entrance end of the partition plate 4, and the mounting device separates the base paper of the label paper from the label paper at the entrance end of the partition plate 4. The front guide roller 8 and the rear guide roller 8 are used to maintain the overall tension of the label tape to avoid problems such as winding and curling. The principle that the partition plate 4 can separate the label from the base paper is that the function of the partition plate 4 is to separate the label from the base paper. There is an angle at one end of the partition plate 4, which is 30 degrees in this embodiment. The function is that when the base paper passes through the partition plate 4, the direction changes, which is conducive to the peeling and separation of the label from the base paper, and the contact with the glass bottle is achieved to complete the labeling work. Under the traction of the power device, when the label tape passes through the partition plate 4, the curvature of the partition plate 4 itself and the stiffness of the label itself interact with each other to overcome the adhesive force between the label and the base paper, thereby achieving the separation of the label.

[0030] Preferably, the partition plate 4 is a straight plate structure, and the inlet end of the partition plate 4 is a curved corner. When the base paper and the label are separated, the angle between the partition plate 4 and the base paper is 30 degrees.

[0031] In this embodiment, the labeling device 3 includes a driving motor 12 and a labeling crawler 13 driven by the driving motor 12. The labeling crawler 13 is located on one side of the conveyor belt 1. It also includes a limit plate 14. The limit plate 14 is located on the other side of the conveyor belt 1. A limit area for limiting glass wine bottles is formed between the labeling crawler 13 and the conveyor belt 1. A limit pad is arranged on the inner side of the limit plate 14. The limit pad is made of sponge or rubber. The space between the limit plate 14 and the conveyor belt 1 is the limit area. With this structural design, when a wine bottle enters this area, due to pressure, the position in contact with the wine bottle will become a curved surface to cover the wine bottle. Driven by the labeling crawler, the label paper attached to the labeling crawler is pasted on the bottle body during the idling process of the wine bottle. The conveyor belt does not work during the labeling process.

[0032] In the labeling state of this embodiment, the distance between the limit plate 14 and the conveyor belt 1 is equal to or slightly less than the thickness or diameter of the glass wine bottle of 0.2mm to 0.5mm. Ensure that there is friction between the wine bottle, the limit plate 14 and the labeling crawler 13. This structure is suitable for round wine bottles with light weight and small size, because the rotation of the wine bottle with larger weight and size requires greater force, and the clamping force between the limit plate 14 and the labeling crawler 13 and the transmission force of the labeling crawler 13 cannot ensure the stable rotation of the bottle. However, the above problem does not exist for wine bottles with a flat surface. The size of the wine bottle using this solution in this embodiment is 75mm in diameter.

[0033] The mounting plate 14 is also included, and a push cylinder 15 is installed on the mounting plate. The push cylinder 15 can drive the limit plate 14 to approach and move away from the labeling crawler 13.

[0034] In this embodiment, the driving roller 10 is driven by a motor, and the driving roller 10 includes a metal roller and a rubber roller. The base paper is clamped between the metal roller and the rubber roller. The motor drives the driving roller 10 and the paper receiving roller 11 to move synchronously, and the two are connected to the driving motor 12 through a synchronous pulley.

[0035] When adjustment is needed, it is only necessary to adjust the position of the push cylinder 15 or adjust the cylinder stroke.

[0036] The specific working process is as follows:

[0037] First, the label tape is installed on the unwinding roller 6, and then it passes through the buffer roller 7, the guide roller 8, the partition plate 4, the driving roller 10, and then the bottom paper is collected by the paper collection roller 11. After the label tape is installed, the driving roller 10 is started, and the friction between the rubber roller and the metal roller drives the label tape to run. At the same time, the paper collection roller 11 will also operate accordingly and the driving roller 10 drives the bottom paper to be collected by the same motor.

[0038] When the label tape passes through the partition plate 4 under the traction of the power device, the curvature of the partition plate 4 and the stiffness of the label itself interact with each other to overcome the adhesive force between the label and the base paper, thereby achieving the separation of the label.

[0039] Before the label moves to the partition plate 4, the label and the base paper are tightly combined, as shown, and the label and the base paper are bonded. When the label belt moves to the partition plate 4, the base paper begins to bend, and the label begins to separate from the base paper due to its own stiffness, as shown, and the label is partially separated from the base paper. As the base paper continues to run, the label and the base paper are separated, and the label continues to move forward under the action of traction, and finally reaches the surface of the bottle body. After the base paper transports the label, it returns to the winding piece under the action of the traction device for recycling. Then the labeling machine performs labeling work. When the wine bottle enters this area, due to pressure, the position in contact with the wine bottle will become a curved surface to cover the wine bottle. Driven by the labeling crawler, the label paper attached to the labeling crawler is pasted on the bottle body during the idling process of the wine bottle. Since the contact surface between the wine bottle and the sponge is a straight line, the position of the label coincides with the area swept by the straight line, so that the label can be evenly and completely pasted on the wine bottle. The conveyor belt does not work during the labeling process.

[0040] Example 2

[0041] The difference from the first embodiment is that it also includes an adjustment mechanism, wherein the adjustment mechanism includes a height adjustment mechanism and a longitudinal adjustment mechanism, the height adjustment mechanism is used to adjust the initial height of the limit plate 14, and the longitudinal adjustment mechanism is used to adjust the initial distance between the limit plate 14 and the labeling crawler 13. Specifically, the limit plate 14 is mounted on the adjustment plate, and the height adjustment mechanism and the longitudinal adjustment mechanism are both realized by screws or adjustment bolts in conjunction with the guide shaft, which are not shown in the figure of this embodiment.

[0042] Example 3

[0043] The difference between this embodiment and embodiment 1 is that this solution uses a cylinder and a labeling guide roller 16 to replace the limit plate 14. The cylinder will push the labeling guide roller 16 to contact the wine bottle. In this case, the wine bottle is limited by the labeling guide roller 16, and a sponge is provided on the surface of the labeling guide roller 16. Therefore, it performs rotational motion instead of linear motion. When the wine bottle is attached to the label, the bottle will rotate with the movement of the sponge under the action of friction, thereby completing the labeling. After the labeling is completed, the push cylinder 15 is released, the wine bottle is transported to the next station, and the push cylinder 15 is ready to clamp the next wine bottle. The conveyor belt does not need to stop working during this process.
