Description

Technical Field

[0001] This invention relates to the field of labeling machine loading and unloading technology, specifically to an automatic loading and unloading structure for labeling machines. Background Technology

[0002] With the rapid development of the packaging automation industry, labeling machines, as a high-efficiency and stable label attaching equipment, are constantly expanding their application scenarios. In the labeling process, the workpiece loading and unloading process is an important part of the labeling operation. The efficiency of its loading and unloading directly affects the overall production efficiency of the labeling machine. Therefore, a high-efficiency automatic loading and unloading structure for labeling machines is needed to complete the workpiece conveying and receiving operation.

[0003] However, the existing loading and unloading structure is not convenient for the regularization and correction of products during the conveying process, which makes it easy for products to be misaligned or placed crookedly during the conveying process. It is difficult to ensure the regularity of the product conveying position and greatly reduces the alignment stability of subsequent labeling operations. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic loading and unloading structure for labeling machines. By setting up a reciprocating part, the existing loading and unloading structures are not convenient for regularizing and correcting the products during the conveying process, which leads to the products being prone to positional deviation and skewed placement during the conveying process. This makes it difficult to ensure the regularity of the product conveying position and greatly reduces the positioning stability of subsequent labeling operations.

[0007] Furthermore, the cleaning unit includes a squeezing assembly mounted on an I-beam bracket; and a pipe assembly disposed on the squeezing assembly.

[0008] Furthermore, the transmission assembly includes a transmission plate fixedly connected to the bottom of the rectangular plate. Two hinge blocks 1 are fixedly connected to the front and rear sides of the transmission plate. Each of the hinge blocks 1 is hinged with a hinge rod, and each of the hinge rods is provided with a connector. The two hinge blocks 1 on the front side and the two hinge blocks 1 on the rear side are mirror images of each other. The connector includes two hinge blocks 2 fixedly connected to the top of the two support plates respectively. Each of the hinge blocks 2 is hinged to a number of hinge rods. There are four hinge blocks 2.

[0009] Furthermore, the support assembly includes C-shaped brackets respectively disposed on the front and rear sides of the I-shaped bracket, with the sides of the two C-shaped brackets that are close to each other extending into the I-shaped bracket, and the two C-shaped brackets being slidably connected to the I-shaped bracket, and the sides of the two C-shaped brackets that are close to each other being fixedly connected to a support plate; the two C-shaped brackets and the two support plates are mirror images of each other.

[0010] Furthermore, the compensation component includes several telescopic rods fixedly connected to the side of the support plate away from the C-shaped bracket. A silicone correction plate is fixedly connected to the side of the several telescopic rods away from the support plate. Springs are sleeved on the outer walls of the several telescopic rods. The side of the several springs away from the support plate is fixedly connected to the silicone correction plate. The side of the several springs close to the support plate is fixedly connected to the support plate. Four telescopic rods are provided and arranged in a linear array.

[0011] Furthermore, the extrusion assembly includes a second rectangular support plate fixedly connected to an I-shaped bracket. A hollow cylindrical rod passes through the second rectangular support plate and is fixedly connected to the second rectangular support plate. A piston plate is slidably connected inside the hollow cylindrical rod. A cylindrical rod is fixedly connected to the bottom of the piston plate. The bottom of the cylindrical rod extends outside the hollow cylindrical rod and is slidably connected to the hollow cylindrical rod.

[0012] Furthermore, the pipe assembly includes a connecting pipe that is connected to the hollow cylindrical rod. The side of the connecting pipe away from the hollow cylindrical rod passes through the second rectangular support plate and extends outward. The connecting pipe is fixedly connected to the second rectangular support plate. An air blowing bucket is connected to the side of the connecting pipe away from the hollow cylindrical rod. The air blowing bucket is located between the transmission plate and the two silicone correction plates.

[0013] The present invention has the following beneficial effects: (1) By setting up a reciprocating part, starting the motor, and driving the rectangular plate to move up and down along the I-shaped support through the cooperation of the rotating shaft, drive rod and transmission rod, the rectangular plate drives the transmission plate to move synchronously. The transmission plate relies on the transmission of hinge block one, hinge rod and hinge block two to pull the two support plates, so that the two C-shaped supports slide towards each other or away from each other on the I-shaped support, so as to realize the centering correction of the conveyed products by the support plate, correct the position of the products on the conveying line, ensure the regularity of the product conveying position, improve the alignment stability of the subsequent labeling operation, and ensure the stable and reliable positioning of the products in the continuous production process. (2) By setting up a correction part, when the two C-shaped brackets move towards each other, the silicone correction plates are brought closer together by the telescopic rod. After the silicone correction plate contacts the larger product, the support plate continues to move and squeezes the telescopic rod and spring to deform it. The elastic force formed by the spring, together with the telescopic rod and the silicone correction plate, completes the correction of products of different specifications. It is compatible with the centering correction of products of various sizes. The flexible contact method can avoid the product surface from being bumped and damaged during the correction process, and ensure the product appearance is intact. (3) By setting up a cleaning section, during the reciprocating movement of the transmission plate, when moving upward, the cylindrical rod is pushed into the hollow cylindrical rod, which drives the piston plate to squeeze the gas inside the hollow cylindrical rod. The gas is sprayed out from the air blowing bucket through the connecting pipe to clean the top of the conveyed product. When the transmission plate moves downward, the piston plate is reset and the gas is drawn through the air blowing bucket and connecting pipe. The continuous circulation achieves uninterrupted cleaning of the top of the product. Relying on the original reciprocating motion of the equipment, continuous air blowing and dust removal are achieved. Before labeling the product, surface dust and impurities are removed to prevent foreign objects from affecting the labeling adhesion effect and ensure the labeling quality.

[0014] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] The cleaning unit 4 includes a squeezing assembly 41 mounted on an I-beam bracket 211; and a pipe assembly 42 mounted on the squeezing assembly 41. The squeezing assembly 41 includes a rectangular support plate 411 fixedly connected to the I-beam bracket 211, a hollow cylindrical rod 412 passing through the rectangular support plate 411, the hollow cylindrical rod 412 being fixedly connected to the rectangular support plate 411, a piston plate 413 slidably connected inside the hollow cylindrical rod 412, a cylindrical rod 414 fixedly connected to the bottom of the piston plate 413, the bottom of the cylindrical rod 414 extending outside the hollow cylindrical rod 412, the cylindrical rod 414 being slidably connected to the hollow cylindrical rod 412, and the bottom of the cylindrical rod 414 being fixedly connected to the transmission plate 221. The rectangular support plate 411 is located in the groove of the I-shaped bracket 211. The pipe assembly 42 includes a connecting pipe 421 connected to the hollow cylindrical rod 412. The side of the connecting pipe 421 away from the hollow cylindrical rod 412 passes through the rectangular support plate 411 and extends outward. The connecting pipe 421 is fixedly connected to the rectangular support plate 411. An air blowing bucket 422 is connected to the side of the connecting pipe 421 away from the hollow cylindrical rod 412. The air blowing bucket 422 is located between the transmission plate 221 and the two silicone correction plates 322. By setting the cleaning part 4, it continuously blows air to remove dust by relying on the original reciprocating motion of the equipment. Before labeling the product, it removes surface dust and impurities, prevents foreign objects from affecting the labeling adhesion effect, and ensures the labeling quality.

[0023] It should be noted that the control of the belt conveyor 111 and the motor 218 in this application can both be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be implemented using existing technologies, such as PLC.

[0024] When in use, start the belt conveyor 111, then place the product to be labeled on the belt conveyor 111. The belt conveyor 111 will transport the product to be labeled to the bottom of the labeling machine for labeling. During this process, motor 218 is started. Motor 218 drives drive rod 216 to rotate via shaft 215. Drive rod 216 drives transmission rod 217 to move within transmission groove 213 on rectangular plate 212. Drive rod 216 pushes the inner wall of transmission groove 213 via transmission rod 217, causing rectangular plate 212 to move up and down on I-shaped bracket 211. Rectangular plate 212 drives transmission plate 221 to move down and back. At this time, transmission plate 221 drives four hinge rods 223 to move via four hinge blocks 222. The four hinge rods 223 are respectively hinged to the four hinge blocks 222, and the four hinge rods 223 are respectively hinged to the two support plates 312 through the four hinge blocks 224. Therefore, during the reciprocating motion of the transmission plate 221, the transmission plate 221 pulls the two support plates 312 to move through the four hinge rods 223. The two support plates 312 respectively drive the two C-shaped brackets 311 to slide on the I-shaped bracket 211 and move closer or further away from each other. At this time, the two support plates 312 will center and correct the products in the conveying process in sequence. As the two C-shaped brackets 311 approach each other, the two C-shaped brackets 311 respectively drive the two silicone straightening plates 322 to approach each other through the corresponding four telescopic rods 321. When encountering a larger product, after the two silicone straightening plates 322 come into contact with the product, the two support plates 312 continue to approach each other. The two support plates 312 respectively compress the corresponding four telescopic rods 321 and four springs 323, causing them to deform and causing the springs 323 to generate elastic force. Under the action of the telescopic rods 321 and the silicone straightening plates 322, the product can be straightened to fit various sizes. During the reciprocating movement of the transmission plate 221, the transmission plate 221 pushes the two cylindrical rods 414 upwards, moving them into the corresponding hollow cylindrical rods 412. The cylindrical rods 414 push the piston plate 413 to move within the hollow cylindrical rods 412. At this time, the piston plate 413 compresses the gas within the hollow cylindrical rods 412 and injects it into the connecting pipe 421, which is then discharged through the air blowing bucket 422, thereby cleaning the top of the product during the conveying process. When the transmission plate 221 drives the cylindrical rods 414 downwards, the cylindrical rods 414 drive the piston plate 413 downwards. The piston plate 413 draws gas into the hollow cylindrical rods 412 through the connecting pipe 421 and the air blowing bucket 422, thus repeatedly cleaning the top of the product during the conveying process. The preferred embodiments of the present invention disclosed above are only for illustrating the present invention. The preferred embodiments do not describe all details exhaustively, nor do they limit the invention to the specific embodiments described. Obviously, many modifications and variations can be made based on the content of this specification. These embodiments are selected and specifically described in this specification to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention. The invention is limited only by the claims and their full scope and equivalents.
