Description

Technical Field

[0001] This utility model relates to the field of automated packaging equipment technology, and in particular to a label conveying device. Background Technology

[0002] In-mold labeling (IMC) technology, as a mature process, has been widely used in the production of plastic products such as food packaging and daily-use containers. In automated IMC production, labels need to be retrieved from a label library and placed into the injection mold, while the molded product is simultaneously removed from the mold. Currently used robotic arms are limited in function, typically only capable of either label retrieval or product removal, resulting in low efficiency. For multi-cavity molds, the retrieved products are arranged in multiple rows, while subsequent visual inspection or packaging stations usually require products to pass through in a single row. Therefore, an additional independent variable-pitch mechanism is often needed to rearrange the products, which not only increases equipment costs, floor space, and system complexity, but also reduces production efficiency and increases the risk of product damage during transfer.

Detailed Implementation

[0022] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0023] See Figures 1-2 , Figure 1 This is a schematic diagram of the structure of a label conveying device according to an embodiment of this application; Figure 2This is a top view of a label conveying device in cooperation with an injection molding machine according to an embodiment of this application. As shown in the figure, the device includes: a mounting beam 100, which is disposed inside the equipment that needs to transport labels, and the mounting beam 100 extends outward to connect with the injection molding machine; a conveying assembly 200, which is mounted on the mounting beam 100; a label picking assembly 400, which is connected to the conveying assembly 200 and driven by the conveying assembly 200; and a product picking assembly 300, which is connected to the conveying assembly 200 and driven by the conveying assembly 200. The product picking assembly 300 includes a first picking part 320 and a second picking part 340 that can move relative to each other. The product picking assembly 300 is configured to achieve the conversion between multi-row and single-row forms of the picked products through the relative movement of the first picking part 320 and the second picking part 340. This integrates the three major functions of label picking, product picking, and distance adjustment into one unit. By the relative movement of the first picking part 320 and the second picking part 340 in the picking assembly 300, the transformation from multiple rows to a single row is completed directly and automatically after the product is picked up. This eliminates the need for a separate and dedicated pitch-changing mechanism in traditional processes, significantly simplifies the equipment structure, reduces the floor space, and improves overall production efficiency.

[0024] See Figure 2 Specifically, in use, the conveying component 200 first drives the label-taking component 400 to extend into the label storage machine to take out the label paper. The conveying component 200 then drives the label-taking component 400 and the part-taking component 300 into the injection molding machine mold 600. The label-taking component 400 conveys the label paper and installs it into the injection molding machine mold 600. The part-taking component 300 takes out the processed product from the injection molding machine mold 600. The conveying component 200 drives the part-taking component 300 to retract. During the retraction process, the part-taking component 300 merges multiple rows of products into a single row and then transports them to the next workstation.

[0025] Specifically, in this embodiment, the product is a paper cup.

[0026] See Figure 1Furthermore, in this embodiment, the conveying assembly 200 includes: a first slide rail 210 disposed on the mounting beam 100 along a first direction; a central sliding member 220 slidably connected to the first slide rail 210; a first driving unit 250 for driving the central sliding member 220 to slide; a second slide rail 230 disposed on the central sliding member 220, the extension direction of which is different from the first direction; a mounting frame 240 slidably connected to the second slide rail 230, the label-taking assembly 400 and the component-taking assembly 300 being mounted on the mounting frame 240; and a second driving unit 260 for driving the mounting frame 240 to slide. By setting the first slide rail 210 and the second slide rail 230, a precise two-dimensional rectangular coordinate motion module is formed. This structure allows the label picking and part picking actions to be positioned independently and precisely in two directions, ensuring that the label picking component 400 can accurately extend into the label library, and that the label picking / part picking component 300 can accurately enter and exit the injection molding machine mold 600, greatly improving the reliability of operation and the repeatability of positioning accuracy.

[0027] Specifically, both the first drive unit 250 and the second drive unit 260 are drive motors and transmission belts, and the drive motors drive the first slide plate 221 or the mounting bracket 240 to slide via the transmission belt.

[0028] See Figure 1 Furthermore, in this embodiment, the middle hand sliding component 220 includes: a first sliding plate 221, slidably connected to the first slide rail 210; a connecting plate 222, the first end of which is disposed along a second direction and connected to the first sliding plate 221; the second end of the connecting plate 222 is disposed along a second direction; the second direction is perpendicular to the first direction on a horizontal plane; a middle hand mounting plate 223, connected to the second end of the connecting plate 222, and the second slide rail 230 is disposed on the mounting plate along the second direction. Through the combined design of the first sliding plate 221, the connecting plate 222, and the middle hand mounting plate 223, a rigid and structurally stable motion transmission component is formed, providing a solid mechanical foundation for the reliable operation of the entire device.

[0029] See Figure 1 , Figure 3 and Figure 4 , Figure 3 This is a retrieval status diagram of a retrieval component 300 with visual detection in an embodiment of this application; Figure 4 This is a detection status diagram of a component 300 with visual detection in an embodiment of this application.

[0030] Furthermore, in this embodiment, the part-retrieving assembly 300 includes: a first mounting plate 310 fixed to the conveying assembly 200; at least one inclined third slide rail 311 fixed to the first mounting plate 310; a first part-retrieving part 320 slidably connected to the third slide rail 311, and having a plurality of first vacuum suction cups 330 thereon; a second part-retrieving part 340 slidably connected to the third slide rail 311, and having a plurality of second vacuum suction cups 350 thereon; a first drive cylinder 360 fixed to the first mounting plate 310 for driving the first part-retrieving part 320 to move along the third slide rail 311; and a second drive cylinder 370 fixed to the first mounting plate 310 for driving the second part-retrieving part 340 to move along the third slide rail 311. By employing an inclined third slide rail 311 combined with an independent drive cylinder, a clever and reliable mechanical pitch-changing solution is provided. This structure utilizes the guiding effect of the inclined track to convert the linear thrust of the drive cylinder into the oblique combined motion of the picking part, thereby efficiently and smoothly realizing the merging and separation of two rows of products. The action is direct, the control is simple, and the reliability is high.

[0031] Specifically, the first picking unit 320 includes a first picking body and a plurality of first mounting positions 321 extending towards the second picking unit 340, with each of the first mounting positions 321 spaced apart. The first vacuum suction cup 330 is fixed to the first mounting position 321. The second picking unit 340 includes a second picking body and a plurality of second mounting positions 341 extending towards the first picking unit 320, with each of the second mounting positions 341 spaced apart. The second vacuum suction cup 350 is fixed to the second mounting position 341. The first mounting positions 321 and the second mounting positions 341 are staggered in a first direction; when the first picking unit 320 and the second picking unit 340 move towards each other to a merged state, each of the first vacuum suction cups 330 and the second vacuum suction cups 350 alternately arranges to form a compact single row. Because the first mounting positions 321 and the second mounting positions 341 are staggered. When the two pick-up sections are combined, they interlock like the teeth of two combs, allowing the products to be arranged closely together, saving space to the maximum extent and providing great convenience for subsequent inspection or packaging stations.

[0032] See Figure 1 Furthermore, in this embodiment, the label-taking component 400 includes: multiple second mounting plates 410 arranged side by side, fixed to the mounting frame 240; and multiple third vacuum suction cups 420, fixed to the second mounting plates 410. The use of multiple vacuum suction cups arranged side by side allows it to pick up multiple labels at once, matching the layout of the multi-cavity mold, thus meeting the production cycle requirements of high-speed production. The structure is simple and efficient.

[0033] See Figure 5 , Figure 5 This is a schematic diagram of the structure of a label conveying device and a vision inspection system in an embodiment of this application.

[0034] Furthermore, in this embodiment, the label conveying device also includes a vision inspection system, which is disposed on the moving path of the picking component 300. Specifically, as an improvement to the above solution, the vision inspection system includes: a first inspection component 510 disposed on the side of the picking component 300; and a second inspection component 520 disposed below the picking component 300. The vision inspection system is directly integrated into the moving path of this conveying device. This allows the product to directly enter the inspection station after completing the pitch change and forming a single row, without needing to be handled and positioned again, achieving "one-stop" automation of picking, pitch change, and inspection, greatly improving inspection efficiency and automation level.

[0035] Specifically, in the return path after the picking-up component 300 picks up the item, the first detection component 510 detects the mouth of the paper cup product, and the second detection component 520 detects the side of the paper cup product. The first detection component 510 is fixed on the flipping mechanism 700 on the side of the picking-up component 300, which can effectively improve space utilization.

[0036] Preferably, the first detection component is provided with two detection cameras, one of which is used to detect the opening of the product when the picking component 300 moves, and the other detection camera is used to detect the inner wall of the product when the picking component 300 moves.

[0037] As can be seen from the above, the label conveying device of this utility model integrates three major functions: label picking, product picking, and pitch changing. Through the relative movement of the first and second picking parts in the product picking assembly, the transformation from multiple rows to a single row is completed directly and automatically after the product is picked up. This eliminates the need for a separate and dedicated pitch changing mechanism in traditional processes, significantly simplifies the equipment structure, reduces the floor space, and improves overall production efficiency.

[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
