DETAILED DESCRIPTION

[0023] To describe the technical content, structural features, achieved purpose and effect 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 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.

[0024] The terms "upper", "lower", "left" and "right" in this application are as follows: Figure 1 The top, bottom, left and right shown in the figure. The "front" and "rear" mentioned in this application are as follows Figure 3 Before and after shown.

[0025] The embodiment of the present application provides a simple cylinder type material storage rack, which is used to store products online to avoid stopping the production line for reel change. Figure 1 , 2 As shown, the simple cylinder type storage rack 100 includes: a frame 10, a lower roller assembly 20, an upper roller assembly 30, a lifting assembly 40 and a traction assembly 50.

[0026] The lower roller assembly 20 is disposed at the bottom of the frame 10 , and includes a plurality of lower rollers 1 rotatably disposed on the frame 10 , the plurality of lower rollers 1 are sequentially arranged along the front-rear direction, and each lower roller 1 extends along the left-right direction.

[0027] like Figure 2 , 3 As shown, the upper roller assembly 30 includes a lifting frame 2 and a plurality of upper rollers 3 rotatably arranged on the lifting frame 2. The plurality of upper rollers 3 are sequentially arranged in the front-to-back direction, and each of the upper rollers 3 extends in the left-to-right direction. The plurality of upper rollers 3 and the plurality of lower rollers 1 are sequentially arranged alternately from front to back. In the front-to-back direction, an upper roller 3 is arranged between two adjacent lower rollers 1, so that the product sequentially passes around the plurality of upper rollers 3 and the plurality of lower rollers 1 in an "S" shape from front to back.

[0028] like Figure 1 , 2 As shown in FIGS. 4 and 5, the upper roller assembly 30 is movably arranged on the frame 10 in the up-down direction, and the upper roller assembly 30 is always located on the upper side of the lower roller assembly 20. When the upper roller assembly 30 approaches the lower roller assembly 20 on the lower side, the distance between the upper roller assembly 30 and the lower roller assembly 20 decreases, and the moving path of the product on the storage rack 100 decreases, achieving the purpose of releasing the product; when the upper roller assembly 30 moves away from the lower roller assembly 20 on the lower side, the distance between the upper roller assembly 30 and the lower roller assembly 20 increases, and the moving path of the product on the storage rack 100 increases, achieving the purpose of temporarily storing the product online.

[0029] like Figure 1 , 3 As shown, the frame 10 includes a cross beam 11 extending in the left-right direction. The cross beam 11 is located on the upper side of the upper roller assembly 30 and extends in the left-right direction. The cross beam 11 has a first end 111 and a second end 112 that are far away from each other. At least part of the lifting assembly 40 is arranged on the cross beam 11.

[0030] like Figure 1 , 4As shown, the lifting assembly 40 is used to drive the upper roller assembly 30 to approach and move away from the lower roller assembly 20. The lifting assembly 40 includes a plurality of tensioning wheels, two transmission chains and a lifting cylinder 6. The plurality of tensioning wheels are rotatably arranged on the crossbeam 11 in sequence along the left-right direction, and the axis line of each tensioning wheel extends along the front-back direction; the two transmission chains bypass the plurality of tensioning wheels respectively, and can be combined with the bypassed tensioning wheels, so that the transmission chains can move back and forth on the frame 10 to reduce the movement resistance; the lifting cylinder 6 is arranged on one side of the frame 10, which includes a cylinder body 61 and a rod body 62 that can move in the up and down direction relative to the cylinder body 61, the rod body 62 extends in the up and down direction, and a transition wheel 63 is rotatably arranged at the protruding end of the rod body 62, the axis line of the transition wheel 63 is parallel to the axis line of each tensioning wheel 4, and is rotatably connected to the rod body 62, and the transition wheel 63 is simultaneously combined with the two transmission chains.

[0031] The plurality of tensioning wheels include a first tensioning wheel 41 disposed adjacent to the first end 111, a second tensioning wheel 42 disposed adjacent to the second end 112, and a third tensioning wheel 43 and a fourth tensioning wheel 44 located between the first tensioning wheel 41 and the second tensioning wheel 42. In the left-right direction, the transition wheel 63 is located between the first tensioning wheel 41 and the first end 111, the third tensioning wheel 43 and the second tensioning wheel 42 are disposed opposite to each other left and right, and the fourth tensioning wheel 44 is arranged between the second tensioning wheel 42 and the third tensioning wheel 43.

[0032] The two ends of each transmission chain are respectively connected to the crossbeam 11 and the lifting frame 2. The two transmission chains are a transmission chain 51 and a transmission chain 52 whose length is shorter than the transmission chain 51. The head end of the transmission chain 51 is connected to the first end 111 of the crossbeam 11, and the tail end of the transmission chain 51 successively passes around the lower side of the transition wheel 63, the upper side of the first tensioning wheel 41, the upper side of the third tensioning wheel 43, the lower side of the fourth tensioning wheel 44 and the upper side of the second tensioning wheel 42, and then hangs down and is connected to the lifting frame 2; the head end of the transmission chain 52 is connected to the first end 111 of the crossbeam 11, and the tail end of the transmission chain 52 successively passes around the lower side of the transition wheel 63, the upper side of the first tensioning wheel 41 and the upper side of the third tensioning wheel 43, and then hangs down and is connected to the lifting frame 2; the back and forth movement of the transmission chain 51 and the transmission chain 52 does not interfere with each other. The tail end of the transmission chain 51 and the tail end of the transmission chain 52 are connected to the lifting frame 2 in a left-right relative manner, and the cross beam 11 is located in the middle of the lifting frame 2 in the front-back direction to ensure the balance of the lifting frame 2 during the lifting process. In the embodiment of the present application, the length of the transmission chain 51 is greater than the length of the transmission chain 52, and the length of the transmission chain 51 is greater than twice the length of the cross beam 11.

[0033] When the rod body 62 of the lifting cylinder 6 is retracted, the transition wheel 63 moves downward and drives the two transmission chains between the first tensioning wheel 41 and the first end 111 to move downward. At this time, the lengths of the two transmission chains between the first tensioning wheel 41 and the first end 111 increase, while the lengths of the transmission chain 51 between the second tensioning wheel 42 and the lifting frame 2, and the lengths of the transmission chain 52 between the third tensioning wheel 43 and the lifting frame 2 decrease, so that the entire upper roller assembly 30 moves upward; when the rod body 62 of the lifting cylinder 6 is extended, the transition wheel 63 moves upward to release the transmission chain between the first tensioning wheel 41 and the first end 111. At this time, the lengths of the transmission chain between the first tensioning wheel 41 and the first end 111 decrease, while the lengths of the transmission chain 51 between the second tensioning wheel 42 and the lifting frame 2, and the lengths of the transmission chain 52 between the third tensioning wheel 43 and the lifting frame 2 increase, so that the entire upper roller assembly 30 moves downward. The lifting cylinder 6 controls the lifting and lowering of the upper roller assembly 30 by storing and releasing the transmission chain between the first tensioning wheel 41 and the first end 111, which is convenient to operate and has a simple structure.

[0034] A sliding mechanism is also provided between the frame 10 and the upper roller assembly 30, and the sliding mechanism includes a pair of guide rails 12 provided on the frame 10 and a pair of sliders 21 provided on the lifting frame 2, one guide rail 12 and one slider 21 are slidably matched, the pair of sliders 21 are relatively provided on the left and right ends of the lifting frame 2, and the pair of guide rails 12 are relatively provided on the frame 10, and both extend in the up and down directions.

[0035] like Figure 2 , 3 As shown, the traction assembly 50 is arranged at the rear end of the frame 10, and the traction assembly 50 includes an upper traction roller 71 and a lower traction roller 72 which are arranged opposite to each other. The upper traction roller 71 is located on the upper side of the lower traction roller 72 and is parallel to the lower traction roller 72. The lower traction roller 72 is connected to a traction motor 73 in a transmission manner, and the traction motor 73 drives the lower traction roller 72 to rotate around its own axis. The upper traction roller 71 is connected to a traction cylinder 74, and the traction cylinder 74 is used to drive the upper traction roller 71 to approach and move away from the lower traction roller 72. The traction cylinder 74 drives the upper traction roller 71 to press the product against the lower traction roller 72. When the lower traction roller 72 rotates, the upper traction roller 71 rotates passively, so that the product is pulled downstream.
