Description

Technical Field

[0001] The utility model relates to the technical field of metal can packing systems, and specifically relates to a multi-layer metal can stack offline mechanism. Background Art

[0002] After the metal cans are processed, a packing system is required to stack and pack them. In order to avoid affecting the efficiency of the metal can stacking system, the above-mentioned packing system needs to have the function of automatically adjusting the height to ensure quick switching of the layer height and stacking of metal cans with different layer heights. After the packing is completed, the metal can stack needs to be taken offline. Conventionally, a forklift is required to take the pallet stacked with metal cans offline, which has low efficiency and is not conducive to quickly replacing the pallet. Content of the Utility Model

[0003] In order to solve the problem of low efficiency of the above-mentioned method of replacing the pallet by forklift, the utility model provides a multi-layer metal can stack offline mechanism.

[0004] The technical solution of the utility model is as follows:

[0005] A multi-layer metal can stack offline mechanism includes a vertical hollow frame arranged at the end of the metal can transportation line. Vertical guide rails are symmetrically arranged on the vertical hollow frame, and a vertical driving mechanism is arranged at the vertical guide rails. The metal can stack can be driven by the vertical driving mechanism and move on the vertical guide rails;

[0006] A horizontal driving mechanism is arranged at the lower end of the vertical hollow frame. The horizontal driving mechanism includes a plurality of horizontally driving rods arranged in parallel and at intervals. A driving belt is sleeved on the plurality of horizontally driving rods, and the height of the driving belt is controlled by an adjustable frame that can be lifted and lowered;

[0007] The adjustable frame includes idler rollers arranged between adjacent horizontally driving rods. At least two parallel idler rollers are arranged, and the idler rollers are parallel to the horizontally driving rods. The upper ends of the idler rollers abut against and support the lower surface of the driving belt for supporting the metal can stack.

[0008] Different from the conventional method of taking offline by forklift, this device is provided with a horizontal driving mechanism under the vertical hollow frame to assist the metal can stack to take offline. At the same time, it is used in cooperation with the adjustable frame to ensure that the metal can stack can be horizontally driven.

[0009] The specific structure of the above adjustable frame is that the adjustable frame further includes a vertically adjustable block that can be lifted and lowered. The vertically adjustable block is fixed at both ends of the idler roller. By adjusting the vertically adjustable block, the lifting and lowering control of all idler rollers can be achieved simultaneously.

[0010] As a preferred solution, an elastic member is provided between the idler roller and the vertical adjusting block, and the elastic direction of the elastic member is the vertical direction. By using the elastic member for pressure bearing cooperation, the contact effect of the horizontal driving mechanism can be better.

[0011] The specific structure of the above-mentioned horizontal driving mechanism is that auxiliary roller groups are arranged at both the front and rear ends of the horizontal driving mechanism, and the upper surface of the auxiliary roller group is not lower than the upper surface of the horizontal driving mechanism.

[0012] To ensure that the adjusting frame can abut against the metal can stack, the highest plane that the adjusting frame can reach is higher than the upper surface of the auxiliary roller group. After moving to abut against the lower surface of the metal can stack and not making the metal can stack higher than the height of the auxiliary roller group, it can be stopped.

[0013] For balance consideration, the adjusting frame is arranged at the middle position of the vertical hollow frame, and multiple idler rollers are symmetrically arranged about the center line of the vertical hollow frame.

[0014] The way to realize driving the driving belt is that a plurality of driving wheels are arranged at intervals along the length direction of the horizontal driving rod, and the driving belt is sleeved on the driving wheels.

[0015] To ensure that the metal can stack is preferentially supported by the auxiliary roller group during the descending process, the upper surfaces of the multiple driving wheels are arranged lower than the auxiliary roller group.

[0016] For balance consideration, a plurality of auxiliary roller groups corresponding to the driving wheels are arranged.

[0017] As a preferred solution, the height of the auxiliary roller group can be adjusted.

[0018] The beneficial effects of the present utility model are as follows: The present utility model is a multi-layer metal can stack offline mechanism, which is different from the existing method of directly using a forklift for offline. By setting a horizontal driving mechanism, an auxiliary roller group and an adjusting frame, the rapid offline of the metal can stack can be realized. And during the above process, the metal can stack preferentially contacts the auxiliary roller group to ensure balanced support, and then the adjusting frame moves upward to abut against the lower surface of the metal can stack, and further the metal can stack can be driven for displacement by the driving belt.

Driving belt; 6. Adjusting frame; 61. Vertical adjusting block; 62. Roller; 7. Auxiliary roller group. Specific embodiments

[0027] As Figure 1 , 2 shown, a multi-layer metal tank stack off-line mechanism includes a vertical hollow frame 1 provided at the end of the metal tank transportation line. The vertical hollow frame 1 is symmetrically provided with vertical guide rails 3, and a vertical driving mechanism 4 is provided at the vertical guide rails 3. Moreover, the metal tank stack can be driven by the vertical driving mechanism 4 and move on the vertical guide rails 3. In this way, after the metal tanks are stacked into a metal tank stack, they can be transported from a high place to a lower place, and then can be transferred by other equipment and a new pallet can be replaced.

[0028] The special design point of this device is that a horizontal driving mechanism 5 is provided at the lower end of the vertical hollow frame 1, and the moving direction of the horizontal driving mechanism 5 is parallel or perpendicular to the transportation direction of the metal tank transportation line, so as to avoid dislocation during the process of moving out the metal tank stack. In the above structure, the horizontal driving mechanism 5 includes a plurality of horizontally driving rods 51 arranged in parallel and at intervals. A driving belt 53 is sleeved on the plurality of horizontal driving rods 51, and the height of the driving belt 53 is controlled by an adjusting frame 6 that can be lifted and lowered. This is an important design point of this device, that is, the metal tank stack is driven to displace by the way that the adjusting frame 6 abuts against the driving belt 53. First of all, it should be noted that the driving belt 53 is a flexible structure. Therefore, even if the metal tank stack falls on it, it is difficult to fit tightly with it. The setting of the adjusting frame 6 can avoid the above problem. Through the action of the adjusting frame 6, the driving belt 53 can be closely attached to the metal tank stack and drive it to move, and during this process, the above-mentioned adjusting frame 6 cannot affect its normal movement.

[0029] Therefore, the specific structure of the above-mentioned adjusting frame 6 is as Figure 1As shown in the figure, the adjusting frame 6 includes idler rollers 62 arranged between adjacent horizontal driving rods 51. At least two parallel idler rollers 62 are provided. It should be noted that each of the above idler rollers 62 is parallel to the horizontal driving rod 51. The upper end of the idler roller 62 abuts against and supports the lower surface of the driving belt 53 of the metal can stack. Since the idler roller 62 can rotate, it can avoid affecting the normal movement of the metal can stack. Moreover, the more the number of the idler rollers 62 is set, the larger the contact area between the driving belt 53 and the metal can stack is, and the greater the friction force is. However, since the weight of the metal can is relatively low, it is not necessary to set a large number of idler rollers 62 to drive its displacement.

[0030] However, it should be noted that the specific structure of the above adjusting frame 6 is that the adjusting frame 6 further includes a vertically adjustable vertical adjusting block 61, and the vertical adjusting block 61 is fixed at both ends of the idler roller 62. By adjusting the vertical adjusting block 61, the lifting control of all the idler rollers 62 can be carried out simultaneously. This adjustment method can avoid difficult use. If a single idler roller 62 is adjusted, the process will be relatively complicated, and the adjustment height is also uncontrollable, and there may be errors.

[0031] On the basis of the above structure, further, an elastic member is provided between the idler roller 62 and the vertical adjusting block 61, and the elastic direction of the elastic member is the vertical direction. Through the pressure-bearing cooperation of the elastic member, the contact effect of the horizontal driving mechanism 5 can be better. That is, the height of the idler roller 62 can be appropriately increased to ensure that the idler roller 62 presses the driving belt 53 to ensure the abutting connection with the metal can stack. And it should be noted that the above height setting cannot support the metal can stack to a relatively high position to avoid the problem of its inclination.

[0032] Through the above structure, it can be realized. Different from the conventional method of using a forklift for off-line, this device sets a horizontal driving mechanism 5 below the vertical hollow frame 1 to assist the metal can stack for off-line. At the same time, through the cooperation of the adjusting frame 6, it is ensured that the metal can stack can be horizontally driven.

[0033] In addition to the above structure, for stability considerations, the specific structure of the above horizontal driving mechanism 5 is that auxiliary roller groups 7 are arranged at both the front and rear ends of the horizontal driving mechanism 5, and the upper surface of the auxiliary roller group 7 is not lower than the upper surface of the horizontal driving mechanism 5. That is to say, in the initial state, after the above metal can stack descends, it is preferentially abutted and supported by the auxiliary roller group 7, and then as the adjusting frame 6 moves upward, it will contact with the metal can stack and drive it to move forward, which can avoid the phenomenon of inclination after contacting the structure in the middle position.

[0034] For this reason, as Figure 3 、 4As shown, to ensure that the adjusting frame 6 can abut against the metal can stack, the highest plane that the adjusting frame 6 can reach is higher than the upper surface of the auxiliary roller group 7. After moving to abut against the lower surface of the metal can stack and not making the metal can stack higher than the height of the auxiliary roller group 7, it can be stopped. A sensor can be set on one side of the vertical hollow frame 1 for monitoring, and the setting method of this device will not be specifically introduced here.

[0035] After that, for balance considerations, the adjusting frame 6 is arranged at the middle position of the vertical hollow frame 1, and multiple supporting rollers 62 are symmetrically arranged about the center line of the vertical hollow frame 1. Ensuring it is at the middle position, so it can be more stable during the lifting process.

[0036] Finally, the way to drive the driving belt 53 is that a plurality of driving wheels 52 are arranged at intervals along the length direction of the horizontal driving rod 51, and the driving belt 53 is sleeved on the driving wheels 52. After setting the driving wheels 52, to ensure that the metal can stack is supported by the auxiliary roller group 7 preferentially during the descending process, the upper surfaces of the plurality of driving wheels 52 are set lower than the auxiliary roller group 7.

[0037] As Figure 4 shown, for balance considerations, a plurality of auxiliary roller groups 7 corresponding to the driving wheels 52 are provided, and the height of the auxiliary roller group 7 can be adjusted. According to actual requirements, the above parameters can be finely adjusted.
