Description

Technical Field

[0001] The utility model relates to the technical field of palletizers, in particular to a movable palletizer. Background Art

[0002] The palletizer automatically stacks cartons that have been loaded into containers in a certain arrangement on pallets or pallets (wood or plastic). It can stack multiple layers and then push them out to facilitate forklift transportation to the warehouse for storage, which can greatly reduce labor and labor intensity.

[0003] When stacking materials, adjacent layers of materials are often staggered to improve the stability of the materials, so the materials need to be turned 90 degrees. Existing palletizers often use unequal speed conveyor belts or set guide rods to turn objects. However, the former requires precise control of the conveyor belt speed, which is costly, while the latter will collide with the outer surface of the material, which is easy to cause damage to the outer surface of the material, resulting in product defects.

[0007] Furthermore, the lifting frame includes a lifting column rotatably connected to the output end of the hydraulic cylinder, and the upper end of the lifting column is respectively fixedly connected to two cross bars and two vertical bars, and the spacing between the two cross bars is the same as the spacing between the two vertical bars.

[0008] Furthermore, a protective pad is provided on one side of each of the horizontal bars and vertical bars close to the material.

[0009] Furthermore, the reversing assembly includes a telescopic block slidably connected to a sliding groove on a fixed cylinder, a spring is provided between the telescopic block and a side wall of the sliding groove of the fixed cylinder, a limiting groove corresponding to the telescopic block is provided on the lifting column, and the telescopic block is slidably connected to the limiting groove so that the lifting column rotates ninety degrees.

[0010] Furthermore, the limiting groove includes four slotted units which are connected end to end in sequence.

[0011] Furthermore, each of the slotted units comprises a first vertical slot, an arc-shaped slot and a second vertical slot which are connected in sequence, and the second vertical slot is connected to the first vertical slot of an adjacent slotted unit.

[0012] Further, the depth of the first vertical groove is greater than the depth of the second vertical groove.

[0013] In the above technical solution, the movable palletizer provided by the utility model has the beneficial effects of:

[0014] Through the rotating mechanism, when the material moves to the lifting frame driven by the conveying roller, the hydraulic cylinder drives the lifting frame to move vertically. When the lifting frame moves to a position higher than the conveying roller, the lifting frame is rotated 90 degrees by the reversing component, and the hydraulic cylinder drives the lifting frame to move to the original position.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0025] See also Figure 1-4 A movable palletizer includes a conveyor frame 1, on which a plurality of rotatable conveyor rollers 11 are arranged, and a rotating mechanism 2 is arranged on the conveyor frame 1, and the rotating mechanism 2 includes a hollow fixed cylinder 21 fixedly connected to the conveyor frame 1, and a lifting frame 22 is arranged in the fixed cylinder 21, and the bottom of the lifting frame 22 is rotatably connected to the output end of a hydraulic cylinder 23, and the hydraulic cylinder 23 is fixedly connected to the conveyor frame 1, and also includes a reversing component 3 arranged on the lifting frame 22 and the fixed cylinder 21. The plurality of conveyor rollers 11 can be driven by belt drive or chain drive.

[0026] Further, the lifting frame 22 includes a lifting column 221 rotatably connected to the output end of the hydraulic cylinder 23, and the upper end of the lifting column 221 is respectively fixedly connected with two cross bars 222 and two vertical bars 223, and the spacing between the two cross bars 222 is the same as the spacing between the two vertical bars 223. The two cross bars 222 are arranged between adjacent conveying rollers 11, and the corresponding conveying rollers 11 reserve space for placing the vertical bars 223, so that the cross bars 222 and the vertical bars 223 will not collide with the conveying rollers 11 during the lifting process.

[0027] Furthermore, each of the cross bars 222 and the vertical bars 223 is provided with a protective pad on one side close to the material, so as to reduce the wear of the cross bars 222 and the vertical bars 223 on the bottom of the material.

[0028] Furthermore, the reversing assembly 3 includes a telescopic block 31 slidably connected to the sliding groove on the fixed cylinder 21, a spring 32 is provided between the telescopic block 31 and the side wall of the sliding groove of the fixed cylinder 21, and a limiting groove 4 corresponding to the telescopic block 31 is opened on the lifting column 221, and the telescopic block 31 is slidably connected to the limiting groove 4 so that the lifting column 221 rotates ninety degrees.

[0029] Furthermore, the limiting groove 4 includes four slotted units 41 connected in sequence head to tail. The four slotted units 41 are connected in sequence, and the first slotted unit 41 is connected to the last slotted unit 41 .

[0030] Furthermore, each of the slotted units 41 includes a first vertical slot 42 , an arc-shaped slot 43 , and a second vertical slot 44 that are connected in sequence, and the second vertical slot 44 is connected to the first vertical slot 42 of the adjacent slotted unit 41 .

[0031] The hydraulic cylinder 23 drives the lifting column 221 to move upward, and the telescopic block 31 is slidably connected to the first vertical slot 42; when the lifting frame 22 moves to a position higher than the conveying roller 11, the telescopic block 31 is slidably connected to the arc slot 43, so that the lifting column 221 drives the cross bar 222 and the vertical bar 223 to rotate ninety degrees, thereby completing the ninety-degree rotation of the material; the hydraulic cylinder 23 drives the lifting column 221 to descend, and the telescopic block 31 is slidably connected to the second vertical slot 44 and the first vertical slot 42 of the adjacent slot unit 41 in turn, and the lifting column 221 descends to the original height, and so on, and the above process is repeated cyclically to complete the rotation of the material.

[0032] Furthermore, the depth of the first vertical groove 42 is greater than the depth of the second vertical groove 44. This allows the telescopic block 31 to slide along the first vertical groove 42 and the arc groove 43, preventing the telescopic block 31 from sliding into the second vertical groove 44, resulting in the inability to rotate the material. The depth of the arc groove 43 is variable. Specifically, at the connection between the first vertical groove 42 and the arc groove 43, the depth of the arc groove 43 is consistent with the depth of the first vertical groove 42. At the connection between the arc groove 43 and the second vertical groove 44, the depth of the arc groove 43 is consistent with the second vertical groove 44, avoiding the problem that the telescopic block 31 cannot slide from the arc groove 43 to the second vertical groove 44. The utility model can also achieve the effect of the telescopic block 31 sliding along the first vertical groove 42 and the arc groove 43 by setting an inclined block (not shown in the figure) at the connection between the second vertical groove 44 and the first vertical groove 42, with the inclined surface facing away from the first vertical groove 42.

[0033] Working principle: When the material moves to the lifting frame 22 driven by the conveying roller 11, the hydraulic cylinder 23 drives the lifting column 221 to move upward, and the telescopic block 31 is slidably connected with the first vertical slot 42; when the lifting frame 22 moves to a position higher than the conveying roller 11, the telescopic block 31 is slidably connected with the arc slot 43, so that the lifting column 221 drives the cross bar 222 and the vertical bar 223 to rotate ninety degrees, thereby completing the ninety-degree rotation of the material; the hydraulic cylinder 23 drives the lifting column 221 to descend, and the telescopic block 31 is slidably connected with the second vertical slot 44 and the first vertical slot 42 of the adjacent slot unit 41 in turn, and the lifting column 221 descends to the original height, and so on, and the above process is repeated cyclically to complete the rotation of the material.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
