Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of unstacking devices, in particular to an automatic unstacking device supporting non-stop. BACKGROUND

[0002] In modern industrial production, automatic unstacking is one of the key processes on the production line. At present, the common unstacking device usually includes a rack, a liftable supporting table, and a material taking mechanical arm.

[0003] The working process is as follows: the stacked plate materials (i.e. material stack) are placed on the supporting table as a whole, the supporting table is initially lifted so that the top layer of the material stack reaches a preset height for the mechanical arm to grab.

[0004] The supporting table is automatically lifted by a thickness of a plate material each time the mechanical arm takes away a plate material, so as to ensure that the top layer of the remaining material stack always maintains at the preset height.

[0005] However, the existing unstacking device has a significant disadvantage: the supporting table must wait until all the plate materials of the material stack are completely taken away, and then it is lowered to the lowest material loading position, and then the new material stack can be transported and positioned on the supporting table by the forklift and other transportation tools.

[0006] This "emptying-lowering-transporting-positioning" material changing process will cause the unstacking operation to be completely interrupted. Other equipment (such as presses, cutting machines, etc.) on the production line relies on the unstacking device for continuous feeding. The production interruption during material changing will cause the entire production line to be temporarily suspended to wait for the completion of the new material stack feeding.

[0007] For modern factories pursuing high efficiency and high productivity, this frequent shutdown restricts the production rhythm and is not conducive to rapid production. In addition, the frequent start and stop of other equipment on the production line is not conducive to the stability and service life of the equipment during long-term operation. SUMMARY

[0080] The secondary lifting moving seat 320 is fixedly connected with the secondary lifting threaded seat, so that the secondary lifting moving seat 320 moves in the up-down direction along with the secondary lifting threaded seat.

[0081] The secondary lifting support piece 330 can rotate relative to the secondary lifting moving seat 320 about an axis perpendicular to the up-down direction. Of course, the secondary lifting moving seat 320 and the secondary lifting support piece 330 are provided with a rotation limiting structure for limiting the rotation position of the secondary lifting support piece 330, so that the secondary lifting support piece 330 can lift the material pile. The rotation limiting structure of the rotating piece is a conventional setting in the art, and the specific structure of the rotation limiting structure will not be described here.

[0082] One end of the secondary lifting support piece 330 is provided as a hinged part, which is arranged outside the main lifting stroke channel and is hingedly connected with the secondary lifting moving seat 320.

[0083] Referring to Figure 3 The secondary lifting support piece 330 is provided with a supporting surface 331 and a turnover driving surface 332.

[0084] The supporting surface 331 is the upper end surface of the secondary lifting support piece 330, which is used for supporting the material pile and lifting the material pile.

[0085] The overturning driving face 332 is the lower end face of the secondary lifting support 330, and is used to contact the material stack. During downward movement of the secondary lifting support 330, after the overturning driving face 332 contacts the material stack, the overturning driving face 332 is limited by the material stack, so that the secondary lifting support 330 is overturned upward relative to the secondary lifting moving seat 320, so that the secondary lifting support 330 can continue to move downward smoothly.

[0086] Specifically, in the embodiment, a plurality of friction-reducing rollers 333 are rotatably installed at the lower end of the secondary lifting support 330. The plurality of friction-reducing rollers 333 are uniformly arranged, and at least two friction-reducing rollers 333 are arranged at the end of the secondary lifting support 330 away from the secondary lifting moving seat 320, and the friction-reducing rollers 333 protrude from the overturning driving face 332.

[0087] The secondary lifting resetting member is arranged between the secondary lifting support 330 and the secondary lifting moving seat 320, and is used to make the secondary lifting support 330 always have a downward overturning tendency relative to the secondary lifting moving seat 320.

[0088] Specifically, in the embodiment, the secondary lifting resetting member is arranged as a torsion spring. In other embodiments, the secondary lifting resetting member can also be arranged as a spring or other conventional elastic structure. Those skilled in the art can select the specific structure of the secondary lifting resetting member.

[0089] The number of the separating devices is set to be multiple, and the multiple separating devices are adjustably installed above the installation table top 110.

[0090] The separating device comprises a magnetic fixing seat 510, a separating connecting frame 520, and a separating execution structure 530.

[0091] The magnetic fixing seat 510 is a conventional component in the art, and the specific structure of the magnetic fixing seat 510 is not selected here. The magnetic fixing seat 510 is used to be magnetically fixed to the installation table top 110. When it is necessary to adjust the position of the magnetic fixing seat 510, the knob of the magnetic fixing seat 510 is rotated to make the magnetic fixing seat 510 no longer magnetically attached to the installation table top 110. Then, the staff moves the magnetic fixing seat 510 to the designated position, and rotates the knob of the magnetic fixing seat 510 again to make the magnetic fixing seat 510 again magnetically attached to the installation table top 110, so as to complete the adjustment of the position of the separating device to adapt to different sizes of the material stack.

[0092] In other embodiments, the adjustment of the position of the separating device relative to the installation table top 110 can also be realized by other adjustment structures.

[0093] The sheet separating execution structure 530 is fixedly installed at the upper end of the sheet separating support 520.

[0094] Specifically, the plurality of sheet separating devices are respectively a first sheet separating device 501 and a second sheet separating device 502. The first sheet separating device 501 and the second sheet separating device 502 are respectively used for adapting to different characteristics of the plate material, and are alternatively used.

[0095] The sheet separating execution structure 530 of the first sheet separating device 501 is a magnetic sheet separator. The first sheet separating device 501 is used for separating the soft magnetic plate material. When the first sheet separating device 501 is close to the soft magnetic plate material, the plate material can be magnetized, and the adjacent two plate materials are separated by the magnetic force, so as to complete the separation of the plate material.

[0096] Referring to Figure 4 , the sheet separating execution structure 530 of the second sheet separating device 502 is a mechanical sheet separating device. Specifically, the second sheet separating device 502 comprises a sheet separating seat body 531, a sheet separating driving member 532, and a sheet separating main body 533.

[0097] The sheet separating driving member 532 is fixedly installed on the sheet separating seat body 531. The sheet separating driving member 532 is a linear motor. In other embodiments, the sheet separating driving member 532 can also be a linear cylinder or other conventional linear driving device. Those skilled in the art can select the specific structure of the sheet separating driving member 532 according to actual needs.

[0098] The sheet separating main body 533 is movably connected to the sheet separating seat body 531. One end of the sheet separating main body 533 away from the main lifting stroke channel is a control end, and the other end close to the main lifting stroke channel is a sheet separating end. The sheet separating end is provided with a sheet separating sawtooth. The control end is hingedly connected to the output end of the sheet separating driving member 532. When the output end of the sheet separating driving member 532 extends to the main lifting stroke channel, the sheet separating end moves along a sheet separating path, so that the sheet separating end swings upward, and the sheet separating sawtooth drives the uppermost plate material to rise, so as to realize the separation of the plate material. Specifically, in this embodiment, the sheet separating path is an arc path.

[0099] The number of the first sheet separating device 501 and the second sheet separating device 502 is both two. The two first sheet separating devices 501 are symmetrically arranged about the center of the main lifting stroke channel, and the two second sheet separating devices 502 are symmetrically arranged about the center of the main lifting stroke channel. The first sheet separating device 501 and the second sheet separating device 502 are respectively symmetrically arranged about the center of the main lifting stroke channel, so that the sheet separating device can simultaneously separate the two ends of the plate material, thereby reducing the probability of adhesion between the adjacent two plate materials.

[0100] Referring to Figure 1 , 2 , 5, a method for using the unstacking device, comprising the following steps:

[0101] S001, the main lifting driving device 210 drives the main lifting support table 220 to move upward, so that the material pile rises along the main lifting stroke channel, and the uppermost end of the material pile is always at a specified height; after the lowermost end of the material pile is higher than the installation table top by a certain distance, the secondary lifting support piece 330 has enough space to flip downward, after the secondary lifting support piece 330 is flipped downward, the secondary lifting driving device 310 drives the secondary lifting moving seat 320 and the secondary lifting support piece 330 to move upward, so that the secondary lifting support piece 330 rises with the main lifting support table 220 and the material pile, and the mechanical arm takes out the sheet metal at the uppermost end of the material pile one by one.

[0102] S002, when the lowermost end of the material pile reaches the secondary lifting stroke channel, the secondary lifting driving device 310 drives the secondary lifting moving seat 320 and the secondary lifting support piece 330 to move upward, the secondary lifting support piece 330 supports the material pile of the remaining sheet metal and makes the material pile move upward along the secondary lifting stroke channel, so that the uppermost end of the material pile is always at a specified height, and the mechanical arm takes out the sheet metal at the uppermost end of the material pile one by one; at the same time, the main lifting driving device 210 drives the main lifting support table 220 to descend, so that the main lifting support table 220 descends to the material placing height.

[0103] S003, the worker places a new material pile on the main lifting support table 220 using a forklift, and then the main lifting driving device 210 drives the main lifting support table 220 to rise along the main lifting stroke channel, so that the new material pile rises, and finally the uppermost end of the new material pile is kept a certain distance from the lowermost end of the old material pile, and the new material pile and the old material pile rise synchronously.

[0104] S004, when the old material pile is completely taken out by the mechanical arm, the secondary lifting driving device 310 drives the secondary lifting moving seat 320 and the secondary lifting support piece 330 to move downward. At the same time, the main lifting mechanism 200 moves the upper end of the new material pile to a specified height. During the downward movement of the secondary lifting support piece 330, the secondary lifting support piece 330 is blocked by the new material pile, causing the secondary lifting support piece 330 to flip upward. Until the secondary lifting moving seat 320 descends to a certain distance from the lowermost end of the material pile, the secondary lifting support piece 330 has enough space to reset, the secondary lifting support piece 330 flips downward, and after the secondary lifting support piece 330 flips downward, the secondary lifting driving device 310 drives the secondary lifting moving seat 320 and the secondary lifting support piece 330 to move upward again, so that the secondary lifting support piece 330 follows the material pile.

[0105] S005, repeat the above steps.

[0106] The preferred embodiments of the present application have been disclosed with specific reference to a preferred embodiment.
