[0001] The utility model relates to the technical field of labeling, in particular to a labeling device. Background Art

[0002] Labeling equipment is a device used for automatic labeling, commonly used in industrial production, to apply labels to products or packaging. The labeling equipment is equipped with a labeling device, which includes an unwinder, a rewinder, and a peeler. The unwinder is used to unwind the label material roll, the peeler is used to peel the label from the glossy paper so that the label can be applied to the moving product, and the rewinder is used to rewind the glossy paper from which the label has been peeled to complete the product labeling.

[0003] To identify beverage information in a beverage bottle, labeling equipment is often used to apply a label containing beverage information to the adhesive area on the bottle. For product aesthetics, some bottles are designed to include multiple convex curved surfaces, resulting in a curved adhesive area on the bottle. However, the labeling device in the labeling equipment is unable to tightly adhere the label to the curved adhesive area on the bottle. This creates a gap between the label and the bottle, reducing its adhesion and making it prone to falling off. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems in the prior art. To this end, the present invention provides a labeling device that can tightly adhere a label to a curved adhesive area on a beverage bottle, thereby preventing the label from falling off.

[0005] The labeling device according to an embodiment of the present invention includes:

[0006] Machine;

[0007] A conveyor belt, which is arranged on the machine platform and is used to transport multiple beverage bottles from back to front;

[0008] a labeling device, the labeling device being arranged on the machine platform and being used to adhere a portion of a label sticker to a curved adhesive area of the beverage bottle on the conveyor belt;

[0009] A bottle pushing device, the bottle pushing device is arranged on the machine platform, the bottle pushing device is arranged in front of the labeling device, and the bottle pushing device is used to push the multiple beverage bottles on the conveyor belt from back to front;

[0010] A support, a pressure roller and an elastic member, wherein the upper and lower ends of the pressure roller are rotatably provided on the support, the gap between the pressure roller and the bottle pushing device is used for the beverage bottle on the conveyor belt to pass through, and the pressure roller is used to abut against the beverage bottle and the label sticker. The support is slidably connected to the machine table so that the pressure roller can approach or move away from the bottle pushing device, and the two ends of the elastic member are respectively connected to the support and the machine table so that the pressure roller can roll the label sticker pasted on the beverage bottle along the curved bonding area of the beverage bottle, and make the label sticker completely adhere to the curved bonding area of the beverage bottle.

[0011] It has at least the following beneficial effects:

[0012] The conveyor belt is used to transport multiple beverage bottles from back to front. When one of the beverage bottles moves to the labeling device, the labeling device adheres a portion of the label to the curved adhesive area of the beverage bottle. Specifically, the label is adhered to the front portion of the curved adhesive area. Similarly, the labeling device can apply labels to the curved adhesive areas of multiple beverage bottles on the conveyor belt. After the label is partially adhered to the curved adhesive area of the beverage bottle, the conveyor belt moves the beverage bottle and the label forward and approaches the bottle pushing device and the pressure roller. As the beverage bottle continues to move, the bottle and the label come into contact with the pressure roller. Under the continuous pushing force of the bottle pushing device and the elastic force of the elastic member, the beverage bottle moves between the pressure roller and the bottle pushing device. Under the action of the elastic member, the pressure roller is able to continuously press against the label on the beverage bottle and rotate, so that the pressure roller and the bottle pushing device can clamp the beverage bottle. The bottle continues to move forward, allowing the pressure roller, under the action of the elastic member, to roll the label sticker along the curved adhesive area of the bottle. Since the label sticker is already partially attached to the curved adhesive area of the bottle, the pressure of the pressure roller completely adheres to the curved adhesive area of the bottle. Finally, under the thrust of the bottle pushing device, the bottle leaves the gap between the bottle pushing device and the pressure roller, completing the labeling of the bottle. The bottle pushing device and pressure roller in this labeling device ensure that the label sticker is completely attached to the curved adhesive area of the bottle, eliminating the gap between the label sticker and the bottle, improving the adhesion of the label sticker, and preventing the label sticker from falling off.

[0041] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention.

[0042] refer to Figures 1 to 4 The labeling equipment of the present utility model comprises:

[0043] Machine 100;

[0044] The conveyor belt 110 is provided on the machine 100 and is used to transport a plurality of beverage bottles from the back to the front;

[0045] The labeling device 300 is provided on the machine 100 and is used to adhere a portion of the label sticker to the curved adhesive area of the beverage bottle on the conveyor belt 110;

[0046] The bottle pushing device 200 is provided on the machine 100 and in front of the labeling device 300. The bottle pushing device 200 is used to push multiple beverage bottles on the conveyor belt 110 from the back to the front.

[0047] The support 120, the pressure roller 130 and the elastic member 140, the upper and lower ends of the pressure roller 130 are rotatably provided on the support 120, the gap between the pressure roller 130 and the bottle pushing device 200 is used for the beverage bottles on the conveyor belt 110 to pass through, the pressure roller 130 is used to abut against the beverage bottles and the label stickers, the support 120 can be slidably connected to the machine 100 so that the pressure roller 130 can approach or move away from the bottle pushing device 200, and the two ends of the elastic member 140 are respectively connected to the support 120 and the machine 100 so that the pressure roller 130 can roll the label sticker pasted on the beverage bottle along the curved bonding area on the beverage bottle, and make the label sticker completely adhere to the curved bonding area of the beverage bottle.

[0048] It is understood that the conveyor belt 110 is used to transport multiple beverage bottles from back to front. When one of the beverage bottles moves to the labeling device 300, the labeling device 300 can cause a portion of the label sticker to be attached to the curved adhesive area of the beverage bottle. Specifically, the label sticker is attached to the front portion of the curved adhesive area. By analogy, the labeling device 300 can cause the curved adhesive areas of multiple beverage bottles on the conveyor belt 110 to be attached with label stickers. After the portion of the label sticker is attached to the curved adhesive area of the beverage bottle, the conveyor belt 110 conveys the beverage bottle and the label sticker attached to the beverage bottle and moves forward and approaches the bottle pushing device 200 and the pressure roller 130. As the beverage bottle continues to move, the beverage bottle and the label sticker attached to the beverage bottle will come into contact with the pressure roller 130. Under the continuous pushing force of the bottle pushing device 200 and the elastic force of the elastic member 140, the beverage bottle can move between the pressure roller 130 and the bottle pushing device 200, and the pressure roller 130 can always press against the label sticker on the beverage bottle and rotate under the action of the elastic member 140, so that the pressure roller 130 and the bottle pushing device 200 have a clamping effect on the beverage bottle.

[0049] The beverage bottle continues to move forward, allowing the pressure roller 130, under the action of the elastic member 140, to roll the label sticker attached to the beverage bottle along the curved adhesive area of the beverage bottle. Since part of the label sticker is already attached to the curved adhesive area of the beverage bottle, the label sticker can be completely attached to the curved adhesive area of the beverage bottle under the rolling action of the pressure roller 130. Finally, under the thrust of the bottle pushing device 200, the beverage bottle leaves the gap between the bottle pushing device 200 and the pressure roller 130, completing the labeling of the beverage bottle. The bottle pushing device 200 and the pressure roller 130 in this labeling device can completely attach the label sticker to the curved adhesive area of the beverage bottle, eliminating the gap between the label sticker and the beverage bottle, improving the adhesion of the label sticker, and preventing the label sticker from falling off.

[0050] In this utility model, reference is made to Figure 1 、 Figure 2 and Figure 7 , the curved surface on the body of the beverage bottle is convex, Figure 2 The shaded portion in the figure is the curved bonding area on the beverage bottle. After the beverage bottle and the label sticker affixed to the beverage bottle come into contact with the pressing roller 130, the beverage bottle is pushed forward by the continuous action of the bottle pushing device 200. Under the thrust of the bottle pushing device 200, the beverage bottle moves forward, and the beverage bottle and the label sticker affixed to the beverage bottle will come into contact with the pressing roller 130, generating pressure. The beverage bottle continues to move forward under the continuous thrust of the bottle pushing device 200. Under the action of the elastic member 140, the pressing roller 130 can adaptively move closer to or further away from the bottle pushing device 200 according to the specific shape of the curved bonding area, so that the pressing roller 130 can always press against the curved bonding area of the beverage bottle, that is, the pressing roller 130 can always press against the label sticker affixed to the beverage bottle, thereby allowing the label sticker to be rolled and completely adhered to the curved bonding area of the beverage bottle. Specifically, in the present invention, when the pressing roller 130 is rolling the label sticker, the pressing roller 130 first moves away from the bottle pushing device 200 and then moves closer to the bottle pushing device 200, that is, the elastic member 140 is first compressed and then expanded. Multiple beverage bottles on the conveyor belt 110 can be moved sequentially between the bottle pushing device 200 and the pressing roller 130.

[0051] As one embodiment of the present invention, a rubber sleeve is provided on the outer wall of the pressure roller 130, through which the pressure roller 130 contacts the beverage bottle and the label. It is understood that the pressure roller 130 contacts the beverage bottle and the label via the rubber sleeve, which elastically deforms, increasing the contact area between the rubber sleeve, the beverage bottle, and the label. Therefore, the rubber sleeve further enhances the rolling effect of the pressure roller 130, allowing the label to adhere more tightly to the curved adhesive area of the beverage bottle.

[0052] refer to Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 and Figure 8 The bottle pushing device 200 includes an interval sorting assembly, a transmission belt 210, and multiple push plates 220. The multiple push plates 220 are all mounted on the transmission belt 210. The gap between two adjacent push plates 220 is used to accommodate a single beverage bottle. The gap between the transmission belt 210 and the pressure roller 130 is used to allow beverage bottles to pass through. The transmission belt 210 is rotatably mounted on the machine 100 so that the push plates 220 push the beverage bottles from back to front. The interval sorting assembly is located behind the transmission belt 210 and is used to arrange the multiple beverage bottles on the conveyor belt 110 in intervals so that the multiple beverage bottles can enter between two adjacent push plates 220 in sequence. The transmission belt 210 is parallel to the front-to-back direction.

[0053] It will be appreciated that after leaving the labeling device 300, the multiple beverage bottles on the conveyor belt 110 continue to move forward and approach the spacing and sorting assembly. Under the action of the spacing and sorting assembly, the multiple beverage bottles on the conveyor belt 110 are arranged in an orderly manner and approach the transmission belt 210. The transmission belt 210 is equipped with multiple push plates 220, and the transmission belt 210 is capable of rotating, so that the multiple push plates 220 on the transmission belt 210 can also rotate with the transmission belt 210. Because the multiple beverage bottles move toward the transmission belt 210 in an orderly manner, the multiple beverage bottles can sequentially enter between two adjacent push plates 220. Under the push of the push plates 220, the multiple beverage bottles can move forward, thereby allowing the pressure roller 130 to roll the multiple beverage bottles on the conveyor belt 110 in sequence. Specifically, the transmission belt 210 drives the multiple push plates 220 to rotate, causing some of the push plates 220 to move above the conveyor belt 110, and these push plates are used to push the beverage bottles on the conveyor belt 110. On the other hand, the transmission belt 210 is also in contact with the beverage bottle, and the transmission belt 210 can also drive the beverage bottle to move forward.

[0054] refer to Figure 8 The interval sorting assembly further includes a support plate 250, which is positioned within the area enclosed by the transmission belt 210. The support plate 250 is used to support the beverage bottles on the conveyor belt 110 via the transmission belt 210. It is understood that as the pressure roller 130 rolls the beverage bottles, the beverage bottles are subjected to a force directed toward the transmission belt 210, pressing the beverage bottles against the portion of the transmission belt 210 opposite the pressure roller 130. At this point, the support plate 250 supports the beverage bottles. Supporting the beverage bottles via the transmission belt 210, the support plate 250 prevents the beverage bottles from shaking during the rolling process, thereby improving the stability of the bottle labeling process. The bottle pushing device 200 further includes a support plate 250, which is positioned within the area enclosed by the transmission belt 210. The support plate 250 is used to support the transmission belt 210, so that the transmission belt 210 and the pressure roller 130 can clamp the beverage bottles.

[0055] refer to Figure 6 and Figure 9 The bottle pushing device 200 also includes a first cylinder 230 and a second cylinder 240. The first cylinder 230 is arranged in front of the second cylinder 240. The piston rod of the first cylinder 230 can extend above the conveyor belt 110, so that the piston rod of the first cylinder 230 blocks the multiple beverage bottles on the conveyor belt 110 from moving forward. The piston rod of the second cylinder 240 can extend above the conveyor belt 110, so that the first beverage bottle located in the front of the multiple beverage bottles is located between the piston rod of the first cylinder 230 and the piston rod of the second cylinder 240. The piston rod of the first cylinder 230 is away from the top of the conveyor belt 110, so that the first beverage bottle moves forward.

[0056] It is understood that as the conveyor belt 110 conveys multiple beverage bottles forward, the piston rod of the first cylinder 230 extends above the conveyor belt 110 and contacts the first beverage bottle in front of the multiple beverage bottles, preventing the multiple beverage bottles from continuing to move forward. Then, the piston rod of the second cylinder 240 extends above the conveyor belt 110 and between the first and second beverage bottles, placing the first beverage bottle between the piston rods of the first and second cylinders 230. The piston rod of the first cylinder 230 then leaves the conveyor belt 110 and no longer blocks the first beverage bottle. Under the action of the conveyor belt 110, the first beverage bottle continues to move toward the drive belt 210.

[0057] After the first beverage bottle continues to move forward by a distance of at least the width of a beverage bottle, the piston rod of the first cylinder 230 extends above the conveyor belt 110 again, and then the piston rod of the second cylinder 240 moves away from the top of the conveyor belt 110. The second beverage bottle and the other beverage bottles continue to move forward, and the second beverage bottle abuts against the piston rod of the first cylinder 230. The piston rod of the first cylinder 230 hinders the movement of the remaining beverage bottles, and the piston rod of the second cylinder 240 extends above the conveyor belt 110 again. The piston rod of the second cylinder 240 extends to the top of the conveyor belt 110. The second beverage bottle is placed between the second beverage bottle and the third beverage bottle, so that the second beverage bottle is located between the piston rod of the first cylinder 230 and the piston rod of the second cylinder 240. Then the piston rod of the first cylinder 230 leaves the top of the conveyor belt 110, and the second beverage bottle begins to move toward the transmission belt 210 under the action of the conveyor belt 110, and so on, so that the multiple beverage bottles on the conveyor belt 110 can be spaced apart from each other, so that the multiple beverage bottles on the conveyor belt 110 can enter between two adjacent push plates 220 on the transmission belt 210 in sequence.

[0058] refer to Figure 3 and Figure 5The labeling equipment further includes a collection tray 160 and a guide plate 150. The collection tray 160 is disposed on the machine platform 100, in front of the bottle pushing device 200, and is used to collect multiple beverage bottles. The guide plate 150 is disposed in front of the bottle pushing device 200. One end of the guide plate 150 is positioned above the conveyor belt 110, and the other end of the guide plate 150 extends into the collection tray 160. The guide plate 150 is used to abut the beverage bottles on the conveyor belt 110, allowing the beverage bottles to move along the guide plate 150 to the collection tray 160. It will be understood that after the beverage bottles are labeled, the conveyor belt 110 moves the beverage bottles forward, away from the bottle pushing device 200. The forward-moving beverage bottles abut against the guide plate 150, which acts as a guide, allowing the beverage bottles abutting against the guide plate 150 to move along the guide plate 150 to the collection tray 160. Specifically, the length direction of the guide plate 150 forms an acute angle with the conveying direction of the conveyor belt 110 .

[0059] refer to Figure 5 A limiting plate 151 is further provided on one end of the guide plate 150. The length direction of the limiting plate 151 is parallel to the length direction of the conveyor belt 110. The limiting plate 151 is used to abut against the beverage bottles on the conveyor belt 110 to prevent the beverage bottles from falling from the conveyor belt 110. It is understandable that the limiting plate 151 can abut against the beverage bottles on the conveyor belt 110 to prevent multiple beverage bottles accumulated on one end of the guide plate 150 from falling from the conveyor belt 110.

[0060] As an embodiment of the present invention, the bottom wall of the collecting tray 160 is tilted downward in a direction away from the conveyor belt 110. It is understandable that when the beverage bottles on the conveyor belt 110 move along the guide plate 150 to the collecting tray 160, since the bottom wall of the collecting tray 160 is tilted downward in a direction away from the conveyor belt 110, the beverage bottles will slide down under their own gravity to the side wall of the collecting tray 160 away from the conveyor belt 110, so that more beverage bottles can be moved to the collecting tray 160, thereby making full use of the space of the collecting tray 160. As an embodiment of the present invention, the labeling equipment also includes a slide rail and a slider. The length direction of the slide rail is perpendicular to the conveyor belt 110. The slide rail is provided on the machine 100, and the slider is provided on the support 120. The support 120 can be slidably connected to the slide rail through the slider.

[0061] refer to Figure 6 and Figure 9The labeling device 300 includes a unwinding roller 310, a rewinding roller 320, and a peeling block 330. The unwinding roller 310 is used to unwind a roll of label stock. The peeling block 330 is used to peel the label sticker from the glossy paper in the unwound label stock roll, allowing the label sticker to extend above the conveyor belt 110. The rewinding roller 320 is used to rewind the glossy paper. It is understood that the unwound label stock is wound around the peeling block 330. Under the action of the peeling block 330, the label sticker in the label stock roll is peeled from the glossy paper, allowing the label sticker to extend above the conveyor belt 110. As the conveyor belt 110 drives the beverage bottle forward, the curved adhesive area of the beverage bottle abuts the portion of the label sticker that extends above the conveyor belt 110, causing a portion of the label sticker to adhere to the curved adhesive area of the beverage bottle. The beverage bottle continues to move forward, the unwinding roller 310 continues to unwind, and the rewinding roller 320 continues to rewind, so that the label sticker on a part of the beverage bottle is completely separated from the glossy paper and moves forward with the beverage bottle.

[0062] Specifically, the label stock roll consists of glossy paper and multiple label stickers, which are affixed to the glossy paper. Glossy paper is relatively soft, while label stickers are relatively hard. The unwound label stock roll is wound onto a peeling block 330, with the scraping end of the peeling block 330 pressing against the unwound glossy paper. As the unwinding roller 310 unwinds and the rewinding roller 320 winds, the glossy paper begins to move, and the scraping end of the peeling block 330 scrapes the glossy paper. Because the label stickers are relatively hard, the label stickers are gradually peeled off the glossy paper at the scraping end of the peeling block 330. As one embodiment of the present invention, the labeling device 300 further includes multiple first traction rollers and multiple second traction rollers. The multiple first traction rollers are used to wind the portion of the unwound label stock roll between the unwinding roller 310 and the peeling block 330, and the multiple second traction rollers are used to wind the portion of the glossy paper between the peeling block 330 and the rewinding roller 320.

[0063] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
