Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging labeling technology, specifically to a labeling production line for barrelled products. Background Technology
[0002] After the barrelled products are filled, they need to be labeled before being stacked. To improve production efficiency, assembly line production is often used. The barrelled products (also referred to as "barrels" in this article) are weighed first. Only barrels that pass the weight test are labeled. This can prevent unqualified products from entering the market.
[0003] During assembly line production, barrelled products are first weighed. Labels are affixed to products that meet the weight requirements. For products that do not meet the weight requirements, the weighing data is transmitted to the controller. The controller then controls the labeling machine not to perform the labeling action on the products that do not meet the weight requirements. The unlabeled barrelled products are then sent to the rework line in the next process.
[0004] However, in actual production, it was found that as the barrelled products are transported to the labeling area along the production line, a labeling machine is placed next to the labeling area. The labeling machine extends a labeling rod and sticks the label adsorbed at the end of the labeling rod onto the barrelled products. However, in the labeling area, the spacing between the barrelled products to be labeled on the production line is not necessarily the same, and it is inevitable that the barrelled products will be placed too densely before labeling, resulting in barrels piling up in the labeling area. Once barrels are piled up, the labeling frequency will be inconsistent with the frequency of barrelled products being delivered, resulting in the problem of missing labels.
[0005] In addition, the positions of the barrelled products to be labeled may not be the same before labeling. For example, some are aligned with the labeling machine at position A, while others are aligned with the labeling machine at position B. This results in some products having their labels pasted at position A and others at position B, which is not conducive to product consistency. Utility Model Content
[0006] The present invention aims to provide a labeling production line for barrelled products to solve the problem in the prior art where products to be labeled are placed too densely on the production line, causing barrel stacking and affecting labeling.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A labeling production line for barrelled products includes a labeling conveyor line and a labeling conveyor line with the same conveying direction, and also includes a temporary placement table, a transfer device, and a blocking mechanism. The temporary placement table is located between the labeling conveyor line and the labeling conveyor line. The transfer device includes a translator, a translator seat, and two pairs of clamps that can move away from or close to each other. The translator is used to drive the translator seat to move back and forth along the conveying direction. Both pairs of clamps are installed on the translator seat. Each pair of clamps is used to clamp a barrel of material after they come close to each other. The transfer device is used to use one pair of clamps to transfer the material on the labeling conveyor line to the temporary placement table, and to use the other pair of clamps to transfer the material placed on the temporary placement table to the labeling conveyor line.
[0009] The blocking mechanism includes a lifting blocking component, which is used to block the continued conveying of materials on the labeling conveyor line. The materials blocked by the blocking component are used to facilitate being held by the clamp.
[0010] The principle and advantages of this solution are as follows: Even if the barrelled products (i.e., materials) on the labeling conveyor line are piled up too densely, the blocking components on the labeling conveyor line will prevent the material at the end of the labeling conveyor line from continuing to be conveyed. The transfer device has two pairs of clamps; one pair holds the material blocked by the blocking components, and the other pair holds the material on the temporary placement table. With the help of a translator, the clamps are moved horizontally, thus transferring the material at the end of the labeling conveyor line to the temporary placement table. The material on the temporary placement table is then transferred to the labeling conveyor line. The labeling machine, located next to the labeling conveyor line, labels the materials after receiving a signal from the controller. This solution, by using the temporary placement table to separate the labeling conveyor line and the labeling conveyor line, and by using the transfer device to transfer the materials one by one, avoids the problem of barrels piling up on the labeling conveyor line, ensuring that every qualified product can be labeled when it is sent for labeling.
[0011] In addition, the blocking mechanism in this solution can not only ensure that the clamp of the transfer device accurately clamps the material on the labeling conveyor line, but also avoid the problem of material spilling from the end of the labeling conveyor line when the material is not transferred by the transfer device in time.
[0012] Preferably, as an improvement, the temporary placement platform is a rotating platform, and a color mark sensor is provided next to the rotating platform. The color mark sensor is connected to the controller, and after the controller receives the signal from the color mark sensor, it controls the rotating platform to stop rotating.
[0013] By using color mark sensors to identify colors at specific locations, it ensures that barrelled products are transferred by the transfer device only after rotating to a specific angle each time. This ensures accurate labeling of materials by the labeling machine next to the subsequent labeling conveyor line, guarantees the consistency of labeling positions, and greatly improves the neatness and aesthetics of product labels.
[0014] Preferably, as an improvement, it also includes a limiting mechanism, and the limiting mechanism and the blocking mechanism are arranged sequentially along the conveying direction of the conveyor line to be labeled. The limiting mechanism includes limiting blocks that can move closer to or further away from each other towards the conveying center line, and the limiting blocks are located above the conveyor line to be labeled. After the blocking mechanism blocks the material, the two limiting blocks of the limiting mechanism move closer to each other to block the material from being conveyed to the end of the conveyor line to be labeled.
[0015] Beneficial effects: This solution sets up a limiting mechanism in front of the blocking mechanism, which can restrict the continued conveying of barrelled products in advance, thereby avoiding the problem of barrelled products piling up at the end of the labeling conveyor line and avoiding the problems caused by the blocking mechanism not blocking in time.
[0016] Preferably, as an improvement, the clamp has an arc-shaped clamping surface, and the clamping surface is elastic, so that the contact area between the clamp and the clamped barrel product is large, thereby increasing the clamping force. In addition, the elastic clamping surface can also prevent damage to the barrel product.
[0017] It also includes a vision inspection system located on the side of the labeling conveyor line. The vision inspection system includes a data acquisition module, which is used to collect image data of the labels affixed to the materials.
[0018] Preferably, as an improvement, it also includes a rejection mechanism and a rework conveyor line. The rework conveyor line is perpendicular to the labeling conveyor line. The rejection mechanism includes rejection blocks that can approach or move away from the rework conveyor line. The rejection blocks and the rework conveyor line are located on opposite sides of the labeling conveyor line. The rejection blocks are used to push the materials on the labeling conveyor line to the rework conveyor line. This solution enables the vision inspection system to detect that the materials are not labeled, and then control the rejection mechanism to start through the controller, thereby driving the rejection blocks to push the materials on the labeling conveyor line to the rework conveyor line, preventing unqualified materials from continuing to move to subsequent processes.
[0019] Preferably, as an improvement, it also includes a lighting device disposed above the labeling conveyor line, the lighting device comprising a support frame and supplementary lights mounted on the support frame.
[0020] After the labels are affixed, the vision inspection system's camera needs to capture the label information on the barrelled product and extract text information from the captured label image to input into the corresponding system for subsequent product traceability. However, insufficient light during camera shooting can affect the image quality. This solution uses supplementary lighting from the lighting device to improve the image quality.
[0021] Preferably, as an improvement, there are three supplementary lights, two of which are located at different heights and are arranged horizontally, and the remaining supplementary light is arranged vertically. This solution uses multiple supplementary lights to improve the lighting in the area of the barreled product being photographed, which further helps to improve the quality of the photographed images.
[0022] Preferably, as an improvement, the support frame is provided with a height adjustment block, which can adjust the installation height on the support frame, and can be locked on the support frame after the height adjustment. The horizontally arranged supplementary light is installed on the height adjustment block to facilitate the height adjustment of the horizontally arranged supplementary light, thereby meeting the supplementary lighting requirements in different situations.
[0023] Preferably, as an improvement, the lighting device further includes a U-shaped shield, which covers the labeling conveyor line. The two wings of the U-shaped shield are parallel to the conveying direction, and the supplementary light is arranged below one of the wings. The light from the supplementary light is directed towards the other wing. The wing on the U-shaped shield facing the supplementary light can block the light from continuing to shine out of the labeling conveyor line. Thus, by using the shield, the effect of supplementary lighting is ensured, while avoiding the glare caused by the light from the supplementary light. Attached Figure Description

[0036] The following detailed description illustrates the specific implementation method:
[0037] The reference numerals in the accompanying drawings include: label conveyor line 10, temporary placement table 20, color mark sensor 21, label conveyor line 30, limiting block 11, limiting driver 12, blocking component 13, lifting device 14, transfer device 40, translation device 41, translation seat 42, clamp 43, clamp body 431, linear driver 432, velvet cloth 4311, labeling machine 50, camera 60, rework line 70, rejection block 81, linearizer 82, support frame 91, supplementary light 92, shielding cover 93, and barrelled product 100.
[0038] Example 1
[0039] Combination Figures 1 to 7 A labeling production line for barrelled products includes a labeling conveyor line 10, a temporary placement platform 20, and a labeling conveyor line 30 arranged sequentially along the conveying direction. A labeling machine 50 and a rework line 70 are arranged sequentially along the conveying direction next to the labeling conveyor line 30.
[0040] The conveying directions of the labeling conveyor line 10 and the labeling conveyor line 30 are the same. The temporary placement table 20 is rotatable and is therefore also called a rotary table 20. A color mark sensor 21 is fixedly installed next to the rotary table 20. The color mark sensor 21 is aligned with the barrelled products on the temporary placement table 20. The top surface of the rotary table 20 is level with the top of the roller conveyor of the labeling conveyor line 10 and the labeling conveyor line 30 to facilitate the transfer of barrelled products by the transfer device 40.
[0041] The labeling conveyor line 10, the labeling conveyor line 30, and the rework line 70 are all roller conveyor lines.
[0042] It also includes a limiting mechanism, a blocking mechanism, and a transfer device 40 arranged sequentially along the conveying direction.
[0043] The limiting mechanism is located above the labeling conveyor line 10 and includes two limiting blocks 11 that can move closer to or further away from each other towards the conveyor center line. The limiting blocks 11 are located above the labeling conveyor line 10, and their movement direction is perpendicular to the conveyor center line. The limiting blocks 11 are driven to move linearly by corresponding limiting drivers 12. When the two limiting blocks 11 move closer to each other, they can limit the continued conveying of the drummed products.
[0044] The blocking mechanism is located at the end of the labeling conveyor line 10 to prevent material from being conveyed to the end of the labeling conveyor line 10. It includes a lifting blocking member 13, which is driven to rise and fall by a lifting device 14. In this embodiment, the blocking member 13 consists of two blocking rods located between two rollers at the end of the labeling conveyor line 10. The blocking member 13 is used to prevent the continued conveying of material on the labeling conveyor line 10. When material obstructs the blocking member 13, the controller activates the upstream limiting mechanism of the blocking member 13 to prevent barrelled products from being conveyed to the end of the labeling conveyor line 10, thus avoiding the problem of barrelled products piling up at the end of the labeling conveyor line 10. In this embodiment, both the limiting drive 12 and the lifting device 14 can be cylinders.
[0045] The transfer device 40 includes a translator 41, a translator base 42, and two pairs of clamps 43 that can move away from or towards each other. The translator 41 is fixedly installed. In this embodiment, the translator 41 is a cylinder. The translator 41 is used to drive the translator base 42 to move back and forth along the conveying direction. Each pair of clamps 43 includes two clamp bodies 431 and a linear actuator 432 that drives the clamp bodies 431 to move linearly. The linear actuator 432 is fixedly installed on the translator base 42. The two clamp bodies 431 of each pair of clamps 43 are symmetrically arranged, and the two clamp bodies 431 in each pair of clamps 43 can move away from or towards each other by being driven by the linear actuator 432. In this embodiment, the linear actuator 432 is a cylinder, and the output shaft direction of the linear actuator 432 is perpendicular to the conveying direction of the labeling conveyor line 30.
[0046] The two clamp bodies 431 of each pair of clamps 43 are used to hold a barrel of material after they come close to each other. The transfer device 40 is used to transfer the material on the labeling conveyor line 10 to the temporary platform 20 using a pair of clamps 43 (the material being transferred was originally blocked by the blocking member 13), and at the same time, it uses another pair of clamps 43 to transfer the material placed on the temporary platform 20 to the labeling conveyor line 30.
[0047] A color mark sensor 21 next to the rotary table 20 is connected to the controller. After the color mark sensor 21 detects the set color, the controller receives the position signal from the color mark sensor 21 and controls the rotary table 20 to stop rotating. This ensures that the barrelled products are rotated to the set angle before being transferred from the rotary table 20, ensuring the consistency of the labeling position during subsequent labeling.
[0048] Both the clamp body 431 and the limiting block 11 of the clamp 43 are made of rubber. The clamping surface of the clamp body 431 is an arc surface, which can provide a larger contact area with the barrel-shaped product 100 when they are in contact (the barrel-shaped products 100 in the attached figure are all represented by dashed lines). A velvet cloth 4311 is pasted on the clamping surface to increase the contact area between the clamp 43 and the barrel-shaped product being clamped, thereby increasing the clamping force and preventing damage to the surface of the barrel-shaped product.
[0049] It also includes a vision inspection system located on the side of the labeling conveyor line 30. The vision inspection system includes a data acquisition module, which is used to collect image data of the labels affixed to the materials. In this embodiment, the data acquisition module uses a camera 60.
[0050] A rejection mechanism is provided on the other side of the labeling conveyor line 30 corresponding to the rework line 70. The rework conveyor line is perpendicular to the labeling conveyor line 30. The rejection mechanism includes a rejection block 81 that can move close to or away from the rework conveyor line. The rejection block 81 is connected to a straightener 82. The straightener 82 is used to drive the rejection block 81 to move back and forth along the conveying direction perpendicular to the labeling conveyor line 30.
[0051] The rejection block 81 is used to push the material on the labeling conveyor line 30 to the rework conveyor line. This allows the vision inspection system to detect when a material is not labeled, and then control the rejection mechanism via the controller. This, in turn, causes the rejection block 81 to push the material on the labeling conveyor line 30 to the rework conveyor line, preventing defective materials from continuing to move to subsequent processes. The rejection block 81 has the same structure as the clamping body 431.
[0052] Example 2
[0053] Combination Figures 8 to 12 This second embodiment is an improvement on the first embodiment as follows:
[0054] To ensure the image quality of the aforementioned visual inspection system, an illumination device is installed above the labeling conveyor line 30. The illumination device includes a support frame 91 and supplementary lights 92 mounted on the support frame 91. There are three supplementary lights 92, two of which are located at different heights and are arranged horizontally, while the remaining supplementary light 92 is arranged vertically. The light sources of all supplementary lights 92 are directed towards the labeling area of the material.
[0055] To capture high-quality images of labels at different labeling positions, the vertically positioned supplementary light 92 is longer than the horizontally positioned supplementary light 92, and is directly fixed to the support frame 91. The horizontally positioned supplementary light 92 is fixed to the support frame 91 via a height adjustment block. The height adjustment block can be adjusted vertically along the support frame 91. Specifically, the support frame 91 can have multiple mounting holes, or the height adjustment block can slide vertically along the support frame 91. After sliding to the desired height, the position of the height adjustment block relative to the support frame 91 is locked using screws.
[0056] To avoid the high brightness of the supplementary light 92 affecting passing workers and to improve the lighting effect, a U-shaped shield 93 is fixed above the support of the labeling conveyor line 30. The U-shaped shield 93 is also fixed on the support frame 91. The U-shaped shield 93 covers the labeling conveyor line 30. The supplementary light 92 is installed below one of the two wings of the U-shaped shield 93, and the other wing abuts against the support of the labeling conveyor line 30 and can block the light from the supplementary light 92 from shining forward. That is, the two wings of the U-shaped shield 93 are one long and one short. Thus, the shield 93 can ensure the effect of supplementary lighting and avoid the glare caused by the light from the supplementary light 92.
