Description

Technical Field

[0001] The utility model belongs to the field of packaging machines and relates to a full-automatic tray lowering mechanism. Technical Background

[0002] The pallet removal mechanism on a traditional pallet packaging machine consists of a pallet rack and a suction cup shaft. The suction cup is mounted on the shaft. The movement of the bagging system drives the suction cup shaft, which then removes the pallet and places it on the feed channel. This pallet removal mechanism requires a groove in the feed channel for the suction cup shaft to descend. Furthermore, the feed channel must remove the pallet before the suction cup shaft can rise to pick up the next pallet. Summary of the Invention

[0003] In view of the above problems, the present invention provides an adjustable bag-supporting structure for a bagging machine. The device has the advantages of being able to flip the tray up and down and having high working efficiency.

[0004] The object of the present invention is achieved like this:

[0005] A fully automatic tray lowering mechanism includes a frame, a tray rack is fixed on the frame, a tray removal outlet is provided below the tray rack, a suction cup shaft is provided below the tray rack, a suction cup is fixed on the suction cup shaft, the suction cup shaft is connected to a suction cup shaft up and down driving mechanism and a suction cup shaft up and down flipping mechanism, the suction cup shaft up and down driving mechanism drives the suction cup shaft to move up and down, and the suction cup shaft up and down flipping mechanism drives the suction cup shaft to flip up and down, so that the tray is flipped up and down.

[0006] The suction cup shaft up-and-down flip mechanism allows the suction cup shaft to flip up and down, thereby flipping the tray on the suction cup up and down, eliminating the need for a groove formed on the feed channel for the suction cup shaft to descend. With the suction cup shaft up-and-down flip mechanism, after the suction cup flips the tray, it can reset and pick up the next tray by lowering the tray, eliminating the need to wait for the feed channel to send the tray away before picking up the next tray, thereby improving work efficiency.

[0007] The utility model is further configured as follows: the up and down flipping mechanism of the suction cup shaft includes a steering block, which is fixedly connected to the suction cup shaft, and a cam is eccentrically arranged on the steering block, and also includes a guide plate, a guide groove is formed on the guide plate, and the cam is arranged in the guide groove, and the guide groove includes a vertical groove and a deviation groove, and the deviation groove is arranged in the middle of the vertical groove, and the center line of the vertical groove and the axis of the suction cup shaft are on the same vertical plane.

[0008] By arranging the steering block, the cam and the deviation slot, when the cam passes through the deviation slot, the suction cup shaft is turned 180 degrees, thereby achieving a 180-degree flipping of the tray.

[0009] The utility model is further configured such that: the distance between the axis of the cam and the axis of the suction cup shaft is equal to the deviation distance of the deviation groove.

[0010] Through the above arrangement, when the suction cup shaft moves from top to bottom, the cam is set under the suction cup shaft, and the cam moves downward accordingly, and the axis of the cam and the axis of the suction cup shaft are in the same vertical plane; when the cam passes through the deviation slot to the farthest distance, the axis of the cam and the axis of the suction cup shaft are in the same horizontal plane. Since the steering block and the suction cup shaft are fixedly connected, the suction cup shaft rotates 90 degrees; when the suction cup shaft continues to move downward with the cam, the suction cup shaft comes to the bottom of the cam first, thereby realizing a 180-degree rotation of the suction cup shaft, and indirectly realizing a 180-degree flip of the tray.

[0011] The utility model is further configured as follows: the deviation distance of the deviation groove is the distance between the farthest point of the left side wall of the deviation groove and the left side wall of the vertical groove.

[0012] The utility model is further configured as follows: the cam is rotatably arranged on the steering block.

[0013] Through the above arrangement, the friction between the cam and the deviation groove when in contact can be reduced, making the flipping smoother and less prone to jamming.

[0014] The utility model is further configured as follows: it also includes a mounting plate, a suction cup shaft bearing is provided in the middle of the mounting plate, and the suction cup shaft is rotatably connected to the mounting plate through the suction cup shaft bearing.

[0015] The utility model is further configured as follows: the suction cup shaft up and down driving mechanism includes up and down driving electric cylinders, and the output end of the driving electric cylinder is fixedly connected to the mounting plate.

[0016] Through the above arrangement, the driving cylinder can drive the suction cup shaft to move up and down, and the rotational connection between the suction cup shaft and the mounting plate can be achieved through the bearing.

[0017] The utility model is further configured as follows: sliders are fixed on both sides of the mounting plate, two vertical slide rails are provided on the frame, and the sliders are slidably arranged on the slide rails.

[0018] By setting the slider rail, the suction cup axis can move up and down more stably without any left or right deviation.

[0019] The utility model is further configured as follows: more than two adjusting blocks are fixed on the suction cup shaft, and each adjusting block is fixed with a suction cup.

[0020] By setting the adjustment blocks, the spacing between the adjustment blocks can be adjusted according to the size of the pallet, thereby adapting to pallets of different sizes.

[0021] The utility model is further configured as follows: an adjusting slot is provided on the adjusting block, an adjusting opening is provided on the adjusting slot, and a loosening screw is provided in the adjusting opening.

[0022] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects: by providing a suction cup shaft up-and-down flipping mechanism, the suction cup shaft is flipped up-and-down, thereby flipping the tray on the suction cup up-and-down, thereby eliminating the need for a groove formed in the feed channel for the suction cup shaft to descend. By providing the suction cup shaft up-and-down flipping mechanism, after the suction cup flips the tray, it can be reset and the next tray can be picked up by placing the tray down, eliminating the need to wait for the feed channel to send the tray away before picking up the next tray, thereby improving work efficiency.

Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0034] A fully automatic tray lowering mechanism includes a frame 1, a tray rack 2 is fixed on the frame 1, a tray removal outlet is provided below the tray rack 2, a suction cup shaft 3 is provided below the tray rack 2, a suction cup (not shown) is fixed on the suction cup shaft 3, the suction cup shaft 3 is connected to a suction cup shaft up and down driving mechanism and a suction cup shaft up and down flipping mechanism, the suction cup shaft up and down driving mechanism drives the suction cup shaft 3 to move up and down, and the suction cup shaft up and down flipping mechanism drives the suction cup shaft 3 to flip up and down, so that the tray 4 is flipped up and down.

[0035] The suction cup shaft up-and-down flipping mechanism is configured to flip the suction cup shaft 3 up-and-down, thereby flipping the tray 4 on the suction cup up-and-down, eliminating the need for a groove formed on the feed channel for the suction cup shaft to descend. By configuring the suction cup shaft up-and-down flipping mechanism, after the suction cup flips a tray, it can reset and pick up the next tray by lowering the tray, eliminating the need to wait for the feed channel to send the tray away before picking up the next tray, thereby improving work efficiency.

[0036] The suction cup shaft up-and-down flipping mechanism includes a steering block 5, which is fixedly connected to the suction cup shaft 3. The steering block 5 is eccentrically provided with a cam 6, and also includes a guide plate 7, which is formed with a guide groove 8. The cam 6 is disposed in the guide groove 8. The guide groove 8 includes a vertical groove 9 and a deflection groove 10. The deflection groove is disposed in the middle of the vertical groove. The centerline of the vertical groove 9 and the axis of the suction cup shaft 3 are in the same vertical plane. By configuring the steering block 5, the cam 6, and the deflection groove 10, when the cam 6 passes through the deflection groove 10, the suction cup shaft 3 is turned 180 degrees, thereby achieving a 180-degree flip of the tray 4.

[0037] The distance between the axis of the cam 6 and the axis of the suction cup shaft 3 is equal to the deviation distance of the deviation slot 10. Through the above arrangement, when the suction cup shaft 3 moves from top to bottom, the cam 6 is below the suction cup shaft 3, and the cam 6 moves downward with the suction cup shaft 3, and the axis of the cam 6 and the axis of the suction cup shaft 3 are in the same vertical plane; when the cam 6 passes the deviation slot 10 to the farthest distance, the axis of the cam 6 and the axis of the suction cup shaft 3 are in the same horizontal plane, and since the steering block 5 and the suction cup shaft 3 are fixedly connected, the suction cup shaft 3 rotates 90 degrees; when the suction cup shaft 3 continues to move downward with the cam 6, the suction cup shaft 3 first comes to the bottom of the cam 6, thereby realizing a 180-degree rotation of the suction cup shaft, and indirectly realizing a 180-degree flip of the tray.

Each adjustment block 16 has an adjustment slot 17, which has an adjustment opening 18. A tightening screw (not shown) is located within the adjustment opening 18.
