Description

Technical Field

[0001] The invention belongs to the field of mechanical technology, and particularly relates to a method for automatically sticking bottle labels. Background Art

[0002] In current technology, labels are often pasted on the bottle body. There are many types of labels, which can be divided into paper labels and adhesive labels based on the material, and can be divided into flat labels and thick labels based on the structure. In the existing technology, automatic labeling can be achieved for flat labels, such as labels on mineral water bottles. However, thick labels, such as labels on glass wine bottles, have a certain thickness and need to be pasted in specific areas, such as in certain grooves. Current technology has many processes and is not easy to achieve automatic pasting due to the high precision requirements of pasting and the hard material, as well as the need to tear off the adhesive protective film. Therefore, the existing technology usually uses manual pasting, but manual pasting has the disadvantages of low pasting efficiency and inconsistent pasting quality. For example, there are differences in the position and pasting angle, so how to achieve bottle pasting? Summary of the invention

[0003] The purpose of the present invention is to provide a method for automatically pasting bottle labels to solve the technical problem that the above-mentioned prior art cannot automatically paste labels.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A method for automatically pasting bottle labels, comprising the following steps:

[0006] S1. Cut the graphics and sizes according to the design requirements to obtain the labels to be pasted;

[0007] S2, putting the labels to be pasted into the raw material conveying device for standby use;

[0008] S3, placing the labels to be pasted on the raw material conveying device evenly on the first conveyor belt through a robot;

[0009] S4, transferring the labels to be pasted on the first conveyor belt, turning them over and placing them on the second conveyor belt;

[0010] S5, removing the adhesive protective film of the label to be pasted on the second conveyor belt;

[0011] S6. The label to be pasted after the adhesive protective film is removed is transferred to the bottle body to be pasted for pasting.

[0012] In the method for automatically pasting bottle labels of the present invention, in step s2, the labels to be pasted are stacked upright with the adhesive backing facing the direction of transportation.

[0013] In the method for automatically pasting bottle labels of the present invention, the robot in step s3 is a vertical flip robot, which places the label to be pasted in step s2 horizontally on the first conveyor belt with the adhesive backing facing upward.

[0014] The present invention provides an automatic bottle label pasting method, wherein the first conveyor belt and the second conveyor belt are tensioned and rotated films with adhesive top surfaces.

[0015] In the automatic bottle label pasting method of the present invention, a label pressing device to be pasted is arranged above the second conveyor belt.

[0016] In the method for automatically sticking bottle labels of the present invention, the bottle is flipped by a horizontal flipping mechanism in step s4.

[0017] In the automatic bottle label pasting method of the present invention, the horizontal flipping mechanism holds the two side surfaces in the width direction during the flipping process of the label to be pasted.

[0018] In the method for automatically pasting bottle labels of the present invention, in step s6, the bottle to be pasted is fixed and clamped at a pasting station.

[0019] The invention discloses an automatic bottle label pasting method, wherein the contact point between the vertical flipping manipulator and the label to be pasted is a suction cup.

[0020] In the method for automatically pasting bottle labels of the present invention, the pasting is achieved by a label grabbing and pressing mechanism in step s6.

[0021] The beneficial effects of the present invention are as follows: a method for automatically pasting bottle labels is proposed, in which the vertically arranged labels to be pasted are vertically flipped to achieve the effect of being placed horizontally and evenly dispersed, and the labels to be pasted are turned over by a horizontal flipping mechanism, and a pressing device is arranged on the second conveyor belt, so that the adhesive protective film on the back of the label to be pasted is left by the adhesive on the second conveyor belt, so as to achieve the effect of tearing off the protective film, and then the prepared film to be pasted is transferred to the position where it needs to be pasted by a grabbing and pressing mechanism and pressed to achieve pasting, and then the pasted bottle body flows to the next station through the assembly line, and the pasting of the next bottle body is repeated, thereby realizing automatic pasting of the label. DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0023] A method for automatically pasting bottle labels, comprising the following steps:

[0024] S1. Cut the graphics and sizes according to the design requirements to obtain the labels to be pasted;

[0025] S2, putting the labels to be pasted into the raw material conveying device for standby use;

[0026] S3, placing the labels to be pasted on the raw material conveying device evenly on the first conveyor belt through a robot;

[0027] S4, transferring the labels to be pasted on the first conveyor belt, turning them over and placing them on the second conveyor belt;

[0028] S5, removing the adhesive protective film of the label to be pasted on the second conveyor belt;

[0029] S6. The label to be pasted after the adhesive protective film is removed is transferred to the bottle body to be pasted for pasting.

[0030] Its working principle is: the labels to be pasted arranged vertically on the conveyor belt are flipped to horizontal intervals through a robot, so as to facilitate the subsequent horizontal flipping. The horizontal flipping is to set a flipping mechanism between the end of the first conveyor belt and the end of the second conveyor belt, so that the labels to be pasted can be turned over, so that the second conveyor belt can take away its adhesive protective film, and it is also convenient for the subsequent label grabbing and pressing mechanism to work. At the same time, the bottle body is positioned by the positioning mechanism. As long as the stroke and strength of the label grabbing and pressing mechanism are set, accurate and standard automatic pasting can be achieved.

[0031] In order to further understand the present invention, in step s2, the labels to be pasted are stacked upright with the adhesive backing facing the direction of transportation, which can simplify the work process. Usually, during the pre-processing of the labels to be pasted, their shapes and patterns have been determined, and their adhesive backing protective films have been set, so that they can be transported and stored in batches, and loading is convenient.

[0032] In order to further understand the present invention, the robot in step s3 is a vertical flipping robot, which places the label to be pasted in step s2 horizontally on the first conveyor belt with the adhesive backing facing up. The structure of the robot can be varied, as long as it can achieve a horizontal posture from vertical. Usually, the height of the material conveying device is higher than the first conveyor belt, and the vertical flipping robot generally has a telescopic function, so that it can gently take and place the label.

[0033] To further understand the present invention, the first conveyor belt and the second conveyor belt are tensioned and rotating rolls with sticky top surfaces, which can prevent the label from sliding on the first conveyor belt and facilitate the second conveyor belt to stick to its adhesive protective film, providing conditions for subsequent film tearing processes.

[0034] In order to further understand the present invention, a label pressing device to be pasted is arranged above the second conveyor belt, so that the adhesive protective film and the second conveyor belt can be bonded more stably. The structure of the second conveyor belt is that one end is a raw material roll and the other end has an active winding wheel, and the belt body is tensioned to form a part that carries the label. Of course, there are some supporting structures at the bottom of the part that carries the label, which will not be elaborated here.

[0035] In order to further understand the present invention, the flipping is performed by a horizontal flipping mechanism in step s4, and the mechanism is arranged between the first conveyor belt and the second conveyor, so that no manual intervention is required, and the speed of the flipping mechanism can be controlled by setting its action frequency.

[0036] In order to further understand the present invention, the horizontal flipping mechanism holds the labels to be pasted on both sides in the width direction during flipping, which will not damage the labels and will not hinder the movement of the devices in the upper and lower processes.

[0037] In order to further understand the present invention, in step s6, the bottle body to be pasted is fixed and clamped at the pasting station, so that the position to be pasted can be standardized and determined, so that the quality after pasting is very stable, and the positioning mechanism can have a variety of structures, such as setting a gripping positioning on the assembly line, and then putting it back after pasting is completed, etc.

[0038] In order to further understand the present invention, the contact point between the vertical flip robot and the label to be pasted is a suction cup, which prevents damage to the surface quality and shape of the label during the posture change process.

[0039] In order to further understand the present invention, in step s6, pasting is achieved by a label grabbing and pressing mechanism, and the structure only needs to be able to achieve vertical grabbing, horizontal movement and then pressing downwards.
