Description

Technical Field

[0001] The invention relates to the field of packaging equipment, and in particular to a straightening production line for strip products. Background Art

[0002] Copper tubes and copper bars are common strip products. After qualified production, they need to be packaged according to customer requirements and product specifications. The common packaging method is bundling packaging and then wrapping packaging. Bundling packaging is to use steel belts or plastic belts to bundle a certain number of strip products into a bundle, while wrapping packaging is to wrap the bundled products with plastic film or paper belts to prevent damage during transportation and storage.

[0003] At present, we have found that due to the use of cranes in the process of bundling and wrapping, the lowered products are tilted and close together. When the tilted and close-fitting products enter the wrapping equipment, they may collide or rub against the film wrapping equipment, causing poor operation of the equipment and even equipment failure, requiring shutdown for maintenance, which seriously affects packaging efficiency. Summary of the invention

[0004] In view of the above, an object of the present invention is to provide a straightening production line for strip products in view of the problems in the prior art.

[0005] A straightening production line for strip products in the present invention includes a conveyor line and a lifting robot assembly arranged in the conveyor line, which includes a plurality of shovels, and the shovels can be lifted and lowered and translated relative to the conveyor line. The lifting and lowering of the shovels are synchronous actions, and the translation of the shovels is an independent action.

[0006] Furthermore, the conveying line includes two independently arranged conveying devices, and the lifting robot assembly is arranged at the joining position of the two conveying devices.

[0007] Furthermore, a fixed lifting seat and a lifting beam slidably arranged inside the lifting seat are arranged at the bottom of each shovel plate, and a driving shaft and a protruding handle installed on the driving shaft are also arranged at the bottom of the lifting seat.

[0008] Furthermore, all the driving shafts are connected via linkage shafts and couplings, and a driving arm is provided on at least one linkage shaft or driving shaft, and the end of the driving arm is connected to a hydraulic cylinder.

[0009] Furthermore, a translation guide rail is installed on the lifting beam, and the shovel plate is slidably matched with the translation guide rail; the shovel plates at the two end positions among the multiple shovel plates are provided with corresponding screw drive mechanisms for driving the shovel plates to translate, and all the shovel plates are connected by a swing rod.

[0010] Furthermore, a slide is provided at the bottom of the shovel plate, and pull plates are installed on both sides of the slide. The pull plates extend rearward and downward, and a fixed plate is installed at the bottom. A hinge shaft is provided on the fixed plate, and a swing seat is installed on the hinge shaft. The swing rod is connected to each swing seat.

[0011] Furthermore, a spring-operated shaft and a sensor matched therewith are installed on the shovel plate.

[0012] Furthermore, the extension length of the shovel plate relative to the spring shifting shaft can be adjusted.

[0013] Beneficial effect: The present invention can effectively solve the problem of close contact and tilting of products by lifting and translating a strip product straightening production line through the shovel plate, avoid collision and friction when the products enter subsequent packaging equipment due to close contact and tilting problems, and improve the packaging efficiency of the products.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] Reference Figures 1 to 8 The straightening production line of a strip product shown in the figure includes a conveyor line, and a lifting robot assembly 2 arranged in the conveyor line, which includes a plurality of shovels 201, and the shovels 201 can be lifted and translated relative to the conveyor line, and the lifting and lowering of the shovels 201 is a synchronous action, and the translation of the shovels 201 is an independent action. Such a design means that when the product is placed on the conveyor line and moved to the lifting robot assembly 2, the product can be lifted and then put down, which can solve the problem of close contact between products. Secondly, during the process of lifting the product, each shovel 201 is translated accordingly according to the actual situation of the product, so that the inclination of the product is corrected to achieve the predetermined straightening effect.

[0017] In this embodiment, the conveyor line includes two independently arranged conveyor devices 101. When the product is placed on the first conveyor device 101, it is lifted by the lifting robot assembly 2 when it is transported to the end and then transported to the second conveyor device 101. This design can better solve the problem of close proximity. By placing the products on the first conveyor device 101 first, and then lifting them one by one by the lifting robot assembly 2, each product is separated from its original position, ensuring that it can be separated from other products.

[0018] In this embodiment, a fixed lifting seat 202 and a lifting beam 203 slidably arranged inside the lifting seat 202 are arranged at the bottom of each shovel plate 201. At the same time, a driving shaft 204 and a lug 205 mounted on the driving shaft 204 are also arranged at the bottom of the lifting seat 202. The rotation of the driving shaft 204 can drive the lug 205 to lift and lower the lifting beam 203. Such a design can achieve accurate and stable lifting and lowering of the product, ensuring the stability of the product during the handling process. In addition, such a design is also convenient for maintenance and can greatly reduce the failure rate and maintenance cost of the equipment.

[0019] In this embodiment, all the drive shafts 204 are connected through the linkage shaft 206 and the coupling. At the same time, a drive arm 207 is provided on at least one linkage shaft 206 or the drive shaft 204. The end of the drive arm 207 is connected to a hydraulic cylinder 208. The hydraulic cylinder 208 can drive the drive arm 207 to rotate, thereby driving the drive shaft 204 and the linkage shaft 206 to rotate synchronously, thereby achieving the synchronous lifting and lowering of all the shovels 201. The advantage of this design is that it can ensure the consistency of the movements between the various drive shafts 204, reducing the unbalanced or unstable handling caused by the asynchronous drive shafts 204. At the same time, due to the stable power transmission of the hydraulic cylinder 208, the accuracy and stability of the entire handling system are also greatly improved.

[0020] In this embodiment, a translation guide rail 209 is installed on the lifting beam 203, and the shovel board 201 is slidably matched with the translation guide rail 209; the shovel boards 201 at the two ends of the multiple shovel boards 201 are provided with corresponding screw drive mechanisms 211 for driving the shovel boards 201 to translate, and all the shovel boards 201 are connected by a swing rod 210. In this design, all the shovel boards 201 translate through the translation guide rail 209 and the screw drive mechanism 211, which can ensure the accuracy and stability of the shovel boards 201. In particular, the shovel boards 201 at the two ends, as the main driving force, are responsible for pushing the movement of the product to achieve the purpose of correction. The other shovel boards 201 are linked through the swing rod 210, which can better protect the products and prevent them from being damaged by friction on the middle shovel board 201. This design not only ensures work efficiency, but also improves product safety.

[0021] In this embodiment, a slide 212 is provided at the bottom of the shovel plate 201, and pull plates 213 are installed on both sides of the slide 212. The screw drive mechanism 211 is also connected to the pull plate 213 in a transmission manner to drive the shovel plate 201 to move horizontally. The pull plate 213 extends backward and downward, and a fixed plate 214 is installed at the bottom. A hinge shaft 215 is provided on the fixed plate 214, and a swing seat 216 is installed on the hinge shaft 215. The swing rod 210 is connected to each swing seat 216. Among them, the function of the pull plate 213 is to drive the shovel plate 201 to move. The swing seat 216 and the hinge shaft 215 play the role of connection, rotation, and constraint. It solves the problem of misalignment caused by different shovel plates 201 when they move synchronously.

[0022] In this embodiment, a spring shifting shaft 217 and a sensor 218 matched therewith are installed on the shovel plate 201 to detect the state of the spring shifting shaft 217. This is the key part of the whole straightening process. When the product reaches the end of the first conveying device 101, the shovel plates 201 at both ends begin to move driven by the screw drive mechanism 211. Because the product is tilted, one spring shifting shaft 217 will first hit the product and trigger the sensor 218. Then the shovel plate 201 will stop when it receives the signal, and the other shovel plate 201 will continue to move until it receives the signal to stop. In this way, the whole device will know the inclination of the product, and can control the corresponding shovel plate 201 to start translation to correct the product. In addition to this design, the inclination angle of the product can also be obtained by, for example, a visual imaging system. But there is no doubt that the design using the spring shifting shaft 217 will be more accurate and stable.

[0023] In this embodiment, the extension length of the shovel plate 201 relative to the spring shifting shaft 217 is adjustable. Specifically, a sliding seat 219 is provided on the shovel plate 201, the spring shifting shaft 217 is installed on the sliding seat 219, and then the shovel plate 201 is driven by the gear drive structure 220 provided behind the shovel plate 201 and the rack 221 provided on the sliding seat 219. Such a design is mainly to adapt to products of different widths. When the width of the product to be packaged changes, it is only necessary to adjust the extension distance of the shovel plate 201 accordingly to achieve smooth correction of products of different widths.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
