Technical Field

[0001] The present invention relates to the technical field of bag labeling, and particularly to a floating brush with weight universal automatic labeling machine. Background Art

[0002] When producing bagged products, it is usually necessary to attach labels to the outer packaging bags of the bagged products. At present, there are some problems when labeling the bags. First, the thicknesses of different bagged products are often different, while the existing bag labeling devices can only label bagged products of the same thickness. Second, some bagged products are light in weight and prone to slipping during labeling, making it difficult to complete the labeling. Summary of the Invention

[0003] The purpose of the present invention is to provide a floating brush with weight universal automatic labeling machine to solve the technical problems in the prior art that the thickness of the bagged products targeted by the bag labeling device is single, and it is difficult to complete the labeling for light-weight bagged products due to slipping.

[0004] To solve the above technical problems, the present invention specifically provides the following technical solutions:

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] As Figure 1 shown, the present invention provides a floating brush weight-attached universal automatic labeling machine, including:

[0029] A belt conveyor line 1, on one side of the top of the belt conveyor line 1, a side plate 11 parallel to its conveying direction is provided, and the belt conveyor line 1 is used for conveying the bag body 8;

[0030] A weight-increasing mechanism 2, the weight-increasing mechanism 2 is arranged inside the side plate 11 and on the top of the belt conveyor line 1, and the weight-increasing mechanism 2 is used for increasing the weight of the bag body 8;

[0031] A weight-increasing zero-position sensor 3, the weight-increasing zero-position sensor 3 is arranged inside the side plate 11 and on the top of the belt conveyor line 1. When the weight-increasing zero-position sensor 3 senses the bag body 8, the weight-increasing zero-position sensor 3 sends a signal to delay and make the weight-increasing mechanism 2 fall to press the bag body 8;

[0032] A labeling mechanism 4, the labeling mechanism 4 is arranged inside the side plate 11 and on the front side of the weight-increasing mechanism 2 in the conveying direction of the belt conveyor line 1, and the labeling mechanism 4 is used for spitting out a label onto the bag body to make the label stick to the bag body 8;

[0033] A floating brush 5, the floating brush 5 is arranged on the front side of the label outlet end of the labeling mechanism 4, and the floating brush 5 is used for smoothing the label stuck to the bag body 8.

[0034] When applying labels, the bag body is automatically or manually placed into the belt conveyor line 1. The belt conveyor line 1 conveys the bag body 8 forward. When the weight zero sensor 3 senses the bag body 8, the weight zero sensor 3 emits a signal with a time delay, causing the weight increasing mechanism 2 to descend and press the bag body 8, thereby preventing the relatively light bag body 8 from slipping on the belt conveyor line 1 due to insufficient weight and small friction. The bag body 8 continues to be conveyed forward. When the bag body 8 completely passes through the weight increasing mechanism 2, the weight increasing mechanism 2 resets. Then, when the bag body 8 is about to reach the label output end at the bottom of the labeling mechanism 4, the labeling mechanism 4 ejects a label sticker to stick the label sticker onto the bag body 8. Then, the bristles of the floating brush 5 can automatically float and adjust according to the thickness of the bag body 8 to smooth the label sticker stuck on the bag body 8. Finally, the bag body 8 with the label applied is sent out by the belt conveyor line 1. The present invention can well complete the labeling of lightweight bagged products, and at the same time, it can be applicable to label bag bodies 8 with different thicknesses, having strong compatibility.

[0035] In an alternative embodiment, a specific structure of the weight increasing mechanism 2 is provided, specifically as Figure 2 shown. The weight increasing mechanism 2 includes a pressing arm 21 disposed inside the side plate 11 and on top of the belt conveyor line 1, and a motor 22 fixedly disposed outside the side plate 11 and driving the pressing arm 21 to rotate.

[0036] In this embodiment, the motor 22 drives the pressing arm 21 to rotate in the forward and reverse directions, so that the front end of the pressing arm 21 presses the bag body 8 and releases the bag body 8.

[0037] In order to reduce the friction between the front end of the pressing arm 21 and the bag body 8, so that after the pressing arm 21 presses the bag body 8, the bag body 8 can still be well conveyed forward under the conveyance of the belt conveyor line 1, as Figure 1 shown, a roller 211 is provided at the front end of the pressing arm 21.

[0038] In order to be able to achieve automatic feedback on the state of the pressing arm 21, as Figure 1 shown, a pressing arm zero position sensor 6 is fixedly disposed inside the side plate 11 and above the pressing arm 21, and an induction piece 212 is provided at the top end of the pressing arm 21. When the pressing arm zero position sensor 6 senses the induction piece 212, the pressing arm 21 is in the open zero position state.

[0039] In an alternative embodiment, a specific structure of the labeling mechanism 4 is provided, specifically as Figure 1As shown in the figure, the labeling mechanism 4 includes an unwinding roller 41 disposed inside the side plate 11, a winding roller 42 disposed inside the side plate 11 and on the side of the unwinding roller 41, a label outlet head 43 disposed inside the side plate 11 and at the bottom of the unwinding roller 41 and the winding roller 42, and a guide roller 44 rotatably disposed inside the side plate 11. Among them, a floating brush 5 is disposed at the front end of the label outlet head 43, a label roll is installed on the unwinding roller 41, and the label strip is pulled out from the unwinding roller 41, turned by the guide roller 44, bypassed around the label outlet head 43, and then turned by other guide rollers 44 and wound by the winding roller 42.

[0040] During labeling, the label on the label strip is ejected at the front end of the label outlet head 43 and pasted onto the bag body 8, and finally smoothed by the floating brush 5. The setting of the guide roller 44 deflects the path of the label strip to avoid interference between the path of the label strip and the structure of the labeling machine.

[0041] In order to better smooth the label stuck on the bag body, as Figure 1 shown, the floating brush 5 is inclined, and the bottom end of the floating brush 5 is inclined towards the front side of the conveying direction of the belt conveyor 1.

[0042] In order to ensure that the label strip always has a constant tension during the label ejection process, so that the label can be smoothly pasted onto the bag body 8, ensuring that the font on the label is not deformed and the labeling is non-slip and has good consistency, the winding roller 42 is a constant-tension winding roller.

[0043] In order to be able to automatically detect label missing and avoid the phenomena of empty labeling and missed labeling, as Figure 1 shown, a label missing sensor 7 is fixedly disposed inside the side plate 11. The label missing sensor 7 is located at the bottom of the unwinding roller 41, and the label strip pulled out from the unwinding roller 41 first passes through the label missing sensor 7 and then bypasses the label outlet head 43.

[0044] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
