Abstract
Description
Technical Field
[0001] The utility model relates to an automatic roll-changing device for ton bag rolls, belonging to the field of packaging machinery. Background Art
[0002] In the field of automatic ton bag packaging, there are mainly two existing bag supply methods: one is ton bag stacking bag supply. For this bag supply method, it is necessary for workers to stack ton bags and then place them at the designated ton bag stack storage position. Since it is manual stacking, it is impossible to ensure the neatness and regularity of the stack shape, which will increase the failure rate of subsequent bag opening and bag loading, reducing the packaging work efficiency. In order to further improve the success rate of bag opening and bag loading, a bag supply method for ton bag rolls is also provided during the production process. However, currently, when changing the roll of ton bag rolls, it is necessary for workers to use a lifting tool to place the ton bag roll at the roll-changing position of the packaging machine, and then manually change the roll after adjusting the position of the ton bag roll. Its roll-changing operation is cumbersome, the equipment downtime is long, affecting the packaging efficiency. However, in most of the existing automatic roll-changing technologies, they are mostly applicable to plastic films, and the automatic heat-sealing film process is adopted during roll-changing, so it is not applicable to the automatic roll-changing requirements of ton bag rolls. Summary of the Utility Model
[0003] In order to solve the problems of low automation degree, high labor intensity of workers, and affecting packaging efficiency during the roll-changing of existing ton bag rolls, the present invention provides an automatic roll-changing device for ton bag rolls, which includes a base 1. On the base 1, there are two working position transfer frames 2 that can move horizontally left and right. At the upper ends of the two working position transfer frames 2, there are two groups of bag roll swing mechanisms 3. The bag roll swing mechanism 3 includes a mounting frame 32. The lower end of the mounting frame 32 is connected to the two working position transfer frames 2. The upper end of the mounting frame 32 is respectively hinged to the middle parts of the lower ends of the two groups of swing frames 31 on the left and right. At the upper end of the swing frame 31, there is a guide rail 33 arranged in the front-back direction. At both the front and rear ends of the guide rail 33, there is a limit mechanism 36, and the limit mechanism 36 is connected to the swing frame 31. On the guide rail 33, there is a bag roll transfer seat 35, and the bag roll transfer seat 35 can be used to support the core shaft end of the ton bag roll A. When the bag roll transfer seat 35 moves to the front working position of the guide rail 33, it can be in contact with the limit mechanism 36 at the front end of the guide rail 33. When the bag roll transfer seat 35 moves to the rear bag-loading position of the guide rail 33, it can be in contact with the limit mechanism 36 at the rear end of the guide rail 33. The front part of the swing frame 31 is hinged to the cylinder rod of a swing cylinder 34, and the cylinder body of the swing cylinder 34 is hinged to the two working position transfer frames 2.
[0004] In front of the base 1, there is a bag supply lifting conveyor 4. When the bag roll swing mechanism 3 is in the bag supply working state, it is located directly behind the bag supply lifting conveyor 4, and the rear part of the bag supply lifting conveyor 4 presses against the ton bag roll A inside the bag roll swing mechanism 3.
[0005] The bag feeding lifting conveyor 4 includes a support frame body 41. The middle part of the support frame body 41 is hinged to the front part of the bag feeding conveyor 43. The middle part of the bag feeding conveyor 43 is hinged to the cylinder rod of the bag feeding lifting cylinder 42. The cylinder body of the bag feeding lifting cylinder 42 is hinged to the lower part of the support frame body 41.
[0006] The limiting mechanism 36 is an electromagnet structure.
[0007] The working principle of the present utility model is as follows:
[0008] A. Assume that the ton bag roll A installed on one set of bag roll swinging mechanisms 3 is in the bag feeding working state. The swinging cylinder 34 of the other set of bag roll swinging mechanisms 3 drives the front part of the swinging frame 31 to swing upward, so that the bag roll transfer seat 35 moves backward and downward along the guide rail 33 to the bag loading position, and a new ton bag roll A is manually installed on the bag roll transfer seat 35.
[0009] B. The swinging cylinder 34 drives the front part of the swinging frame 31 to swing downward to return to the initial position, so that the bag roll transfer seat 35 drives the new ton bag roll A to move forward along the guide rail 33 to the working position and waits for roll change.
[0010] C. When the ton bag roll A in the bag feeding working state is used up, the packaging machine pauses operation. The bag feeding lifting cylinder 42 drives the bag feeding conveyor 43 to descend to the low position. The two-position transfer racks 2 move along the base 1, so that the bag roll swinging mechanism 3 with the new ton bag roll A is located directly behind the bag feeding conveyor 43. The bag feeding lifting cylinder 42 drives the bag feeding conveyor 43 to rise, so that it presses tightly on the new ton bag roll A, and the roll change is completed.
[0011] D. The packaging machine starts to operate. The new ton bag roll A continues to send the ton bags to the bag feeding conveyor 43, and the bag feeding conveyor 43 conveys the ton bags to the front bag opening position for subsequent bag opening and bag loading actions.
[0012] The beneficial effects of the present utility model are as follows:
[0013] A. By using the two sets of bag roll swinging mechanisms 3 arranged on the two-position transfer racks 2 and cooperating with the swinging and tilting of the swinging frame 31, the bag roll transfer seat 35 moves back and forth along the guide rail 33. The new ton bag roll A is replaced at the low-position bag loading position of the bag roll transfer seat 35. The operation is simple, and one person can complete the bag roll loading action. It also realizes the automatic switching and connection during the replacement of the old and new ton bag rolls A, improves the working efficiency of ton bag roll change, reduces the labor intensity of personnel, greatly shortens the downtime, and improves the production efficiency of ton bag packaging.
[0014] B. By utilizing the coordinated cooperation between the bag delivery lifting conveyor 4 and the bag roll swinging mechanism 3, when the two-station transfer rack 2 moves left and right to change rolls, the bag delivery lifting conveyor 4 can be in a low position, avoiding the friction between the ton bag roll A and the bag delivery conveyor 43 during the transfer of the ton bag roll A and damaging the ton bag; when in the bag delivery working state after the roll change, the ton bag roll A on the bag roll swinging mechanism 3 is always pressed against the bag delivery conveyor 43, ensuring the reliability of the bag delivery work after the roll change.
[0015] C. By using the limiting mechanism 36 provided on the swing frame 31, the positions of the bag loading position and the working position can be kept unchanged. After the new ton bag roll A is manually installed, the bag roll transfer seat 35 will not arbitrarily drive the ton bag roll A away from the bag loading position, and can also ensure the stability and reliability of the ton bag roll A after being transferred to the working position.
[0016] D. The limit mechanism 36 is an electromagnet structure, which has a simple structure, occupies a small space, is low in cost, and is easy to replace and repair. The electromagnet can adsorb the bag roll transfer seat 35 when working, further improving the controllability of the ton bag roll A after installation. BRIEF DESCRIPTION OF THE DRAWINGS
