[0025] In order to describe the technical content, structural features, achieved purposes and effects of the application in detail, the technical solutions in the embodiments of the application will be described below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all of the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but are not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0026] An embodiment of the present application provides an automatic material storage device, which is arranged between the production equipment and the winding equipment, and is used to temporarily store products that are not able to be wound or changed in time. The production equipment is located in front of the winding equipment, and the products are transported from front to back in the automatic material storage device.

[0027] like Figure 1 、 2 As shown, the automatic material storage device includes: a material storage frame 1, an upper material storage mechanism 2 that can be installed on the material storage frame 1 and can move up and down, a lower material storage mechanism 3 that is fixedly installed on the material storage frame 1, a synchronous transmission mechanism 4, a linear guide mechanism 5, a driving mechanism 6 and a traction mechanism 7.

[0028] The storage frame 1 includes a base 11, four columns 12, a pair of first beams 13 arranged opposite to each other in the front and rear, and a pair of second beams 14 arranged opposite to each other in the left and right. The projection of the base 11 from top to bottom is a quadrilateral. The four columns 12 are respectively installed on the four corners of the base 11. Each column 12 extends in the up and down direction. A first beam 13 is fixedly connected between the tops of each pair of columns 12 arranged opposite to each other in the left and right, and a second beam 14 is fixedly connected between the tops of each pair of columns 12 arranged opposite to each other in the front and back.

[0029] The upper storage mechanism 2 includes a pair of upper mounting plates 21 arranged opposite to each other on the left and right sides and a plurality of upper aluminum rollers 22 respectively mounted between the pair of upper mounting plates 21 and rotatably mounted around their own axis. The plurality of upper aluminum rollers 22 are arranged at intervals along the front-to-back direction and are parallel to each other.

[0030] The lower material storage mechanism 3 includes a pair of lower mounting plates 31 arranged opposite to each other on the left and right sides and a plurality of lower aluminum rollers 32 respectively mounted between the pair of lower mounting plates 31 so as to rotate around their own axis. The bottom of each lower mounting plate 31 is fixedly mounted on the base 11; the plurality of lower aluminum rollers 32 are arranged at intervals along the front-to-back direction and are parallel to each other, and the plurality of lower aluminum rollers 32 and the plurality of upper aluminum rollers 22 are alternately distributed from front to back and are parallel to each other.

[0031] like Figure 1-3 As shown, the synchronous transmission mechanism 4 is connected between a pair of upper mounting plates 21 and the storage rack 1, and the synchronous transmission mechanism 4 is used to synchronize the lifting and lowering of the pair of upper mounting plates 21. The synchronous transmission mechanism 4 includes at least one chain transmission assembly 41, and at least one chain transmission assembly 41 is connected between the upper storage mechanism 2 and the storage rack 1. The chain transmission assembly 41 includes an upper transmission shaft 411, a lower transmission shaft 412, a pair of upper transmission sprockets 413, a pair of lower transmission sprockets 414 and a pair of transmission chains 415. The upper transmission shaft 411 and the lower transmission shaft 412 are arranged opposite to each other in the upper and lower directions and are both parallel to the lower aluminum roller 32. The upper transmission shaft 411 is rotatably mounted on a pair of second crossbeams 14, and the lower transmission shaft 412 is rotatably mounted on the base 11. A pair of upper transmission sprockets 413 are coaxially sleeved on both ends of the upper transmission shaft 411, and the lower transmission sprockets 414 are coaxially sleeved on both ends of the lower transmission shaft 412. Each transmission chain 415 is simultaneously engaged with an upper transmission sprocket 413 and a lower transmission sprocket 414 on the same side, and each transmission chain 415 is fixedly connected to the upper mounting plate 21 on the same side.

[0032] When one of the upper mounting plates 21 is raised or lowered under the drive of the drive mechanism 6, the transmission chain 415 connected to the upper mounting plate 21 drives the meshed upper transmission sprocket 413 and lower transmission sprocket 414 to rotate, and at the same time, the upper transmission shaft 411 and the lower transmission shaft 412 are driven by the transmission sprocket at the end to rotate, and the upper transmission sprocket 413 and the lower transmission sprocket 414 on the other side rotate synchronously, driving the transmission chain 415 on the same side to pull the upper mounting plate 21 on the other side to rise and fall synchronously. The synchronous transmission mechanism 4 ensures the synchronous lifting of a pair of upper mounting plates 21, so that each upper aluminum roller 22 is always parallel to the lower aluminum roller 32 during the lifting process, avoiding uneven tension of the product and deformation and being broken when the upper aluminum roller 22 is tilted and lifted, ensuring the stability of the upper storage mechanism 2 during storage and release, and thus ensuring the quality of the product. In the embodiment of the present application, the synchronous transmission mechanism 4 includes a pair of chain transmission assemblies 41, and the pair of chain transmission assemblies 41 are arranged relative to each other in front and back, further improving the stability of the synchronous lifting of the pair of mounting plates 21.

[0033] The linear guide mechanism 5 includes a guide rail 51 extending in the up and down directions and a slider 52 slidingly cooperated with the guide rail 51. A guide rail 51 is installed on each column 12, and a slider 52 is respectively installed at the front and rear ends of each upper mounting plate 21. The linear guide rails at the front and rear ends of the upper mounting plate 21 cooperate to guide the lifting and lowering of the upper storage mechanism 2, avoid longitudinal and lateral displacement of the upper storage mechanism 2 during lifting, and improve the stability of lifting.

[0034] The driving mechanism 6 is mounted on the storage frame 1 and connected to one of the upper mounting plates 21 to drive the entire upper storage mechanism 2 upward away from the lower storage mechanism 3 .

[0035] The upper storage mechanism 2 has a release position and a storage position under the drive of the drive mechanism 6. The release position is located below the storage position. When the upper storage mechanism 2 is in the release position, the plurality of upper aluminum rollers 22 are located below the plurality of lower aluminum rollers 32, and the products pass through the upper side of the plurality of upper aluminum rollers 22 and the lower side of the plurality of lower aluminum rollers 32; when the upper storage mechanism 2 is in the storage position, the plurality of upper aluminum rollers 22 are located above the plurality of lower aluminum rollers 32, and the products pass through each upper aluminum roller 22 and each lower aluminum roller 32 in an "S" shape from front to back. At this time, the movement path of the products through the automatic storage device is greater than the movement path of the upper storage mechanism 2 when it is in the release position, so that the stopped products are temporarily stored in the automatic storage device.

[0036] The driving mechanism 6 includes a driving cylinder 61 and a proportional valve (not shown in the figure). The proportional valve is connected to the driving cylinder 61 to adjust the gas flow of the driving cylinder 61. In the present application, a preset value S is set for the proportional valve. This preset value S corresponds to a certain pulling force F of the driving cylinder 61. When the pulling force F is slightly greater than the gravity G of the upper storage mechanism 2, the upper storage mechanism 2 will rise under the pulling force F of the driving cylinder 61. Therefore, when there is no time to rewind or when there is a pile of products when changing rolls, the upper storage mechanism 2 will rise under the pulling force of the driving cylinder 61, moving from the release position to the storage position, thereby temporarily storing the piled materials. When the upper storage mechanism 2 rises to a certain height, the piled materials are stored and the products will generate a downward tension F. N , this tension F N The sum of the force and gravity G must be greater than the pulling force F. At this time, the upper storage mechanism 2 descends and moves from the storage position to the release position. The descent means the release of the storage material. When the materials are released to the product accumulation, the upper storage mechanism 2 starts to rise again. In this way, the upper storage mechanism 2 completes the storage and release of the products in the continuous rising and falling, and plays a buffering role for the products between the production equipment and the winding equipment.

[0037] The traction mechanism 7 is fixedly mounted on the rear end of the storage frame 1, providing power for the transportation of products and ensuring that the products are subjected to equal traction. The traction mechanism 7 includes a support frame 71, an upper traction roller 72, a lower traction roller 73, a traction cylinder 74, and a traction motor 75. The support frame 71 is fixedly mounted on the storage frame 1. The upper traction roller 72 and the lower traction roller 73 are mounted on the support frame 71 so as to rotate relative to each other and parallel to each other. The lower traction roller 73 is parallel to the lower aluminum roller 32. The traction cylinder 74 is in transmission connection with the upper traction roller 72 to drive the upper traction roller 72 to press the products against the lower traction roller 73. The traction motor 75 is in transmission connection with the lower traction roller 73 to drive the lower traction roller 73 to rotate around its own axis.

[0038] A transition roller 8 is installed and rotated at the front and rear ends of the storage frame 1. Each transition roller 8 is parallel to the lower aluminum roller 32. A pair of transition rollers 8 are respectively located at the front and rear sides of the lower storage mechanism 3, which play a transition and flattening role for the products to enter and exit the automatic storage device.

[0039] The outer side of each lower mounting plate 31 is provided with a limiter 9, which is connected to the driving cylinder 61. The driving mechanism 6 further comprises a resistance scale 62 provided at the driving cylinder 61, which is used to detect the lifting distance of the upper storage mechanism 2.

[0040] This application uses a proportional valve to control the gas flow of the drive cylinder, achieving flexible lifting and lowering to meet production needs. A synchronous transmission mechanism ensures uniform tension on the product, preventing deformation and breakage, and ensuring stable storage. An auxiliary traction device is also included to automatically pull the product into storage. This automatic storage device not only addresses the shortcomings of passive systems that are prone to stretching and breaking, but also solves the cumbersome tension control problems of motor-driven systems. It offers advantages such as low fluctuation, stable storage, and easy control.

[0041] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application.
