DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] Embodiment 1

[0031] like Figures 1 to 7As shown, a destacking device for automatic destacking at a double station described in an embodiment of the present invention comprises a plurality of transfer columns 1, a hydraulic cylinder 2 is fixedly connected between the plurality of transfer columns 1, a placement seat 3 is placed between the plurality of transfer columns 1, a plurality of boxes 4 are placed on one side of the placement seat 3, a fourth motor 37 is fixedly connected to one side of the plurality of transfer columns 1, a second threaded rod 38 is fixedly connected to the output end of the plurality of fourth motors 37, a lifting block 32 is slidably connected to one side of the plurality of transfer columns 1, the plurality of lifting blocks 32 are threadedly connected to the second threaded rod 38, a transfer box 30 is rotatably connected between two corresponding lifting blocks 32, the two transfer boxes 30 are used to transfer the boxes 4 respectively, a second slide plate 25 is provided between the plurality of transfer columns 1, a second slider 26 is slidably connected to one side of the second slide plate 25, a reciprocating device is provided on one side of the second slide plate 25 and the second slider 26, and the reciprocating device is used to reciprocate the second slide plate 25 and the second slider 26.

[0032] Specifically, when splitting wooden box stacks, the boxes 4 are clamped by large gantry and other lifting devices, and the boxes 4 are separated from the stacks one by one for transportation. Such large clamping equipment can only split wooden box stacks in a large space, and cannot split wooden box stacks in a small space. In addition, the efficiency of transporting the boxes 4 one by one is slow, and when clamping the boxes 4, a squeezing force exceeding the weight of the boxes 4 is usually required to generate a sufficiently large friction force to clamp the boxes 4. If the pressure of clamping the boxes 4 is too large, the boxes 4 themselves will be damaged, and if the pressure is too small, the boxes 4 will fall due to insufficient friction.

[0033] In this embodiment, the two transfer boxes 30 are double stations. First, the transfer column 1 is moved to the side of the box body 4, and the box body 4 is stacked and placed on the placement seat 3. The hydraulic cylinder 2 is started to adjust the distance between the multiple transfer columns 1 so that the stack formed by the box body 4 is located between the multiple transfer columns 1. The fourth motor 37 is started to rotate the second threaded rod 38. The second threaded rod 38 rotates so that the lifting block 32 can slide on the transfer column 1. The lifting block 32 moves up and down to the top layer of the box body 4. The second slide plate 25 and the second slider 26 are moved by the reciprocating device to push the top layer of the box body 4 into the transfer box 30. The second slider 26 can slide in the second slide plate 25 without affecting the movement of the multiple transfer columns 1 driven by the hydraulic cylinder 2. The fourth motor 37 is then used to move the lifting block 32 with the transfer box 30 downward, and the box body 4 is transferred from the stack of the placement seat 3 for processing and use. In this way, The telescopic operation of multiple hydraulic cylinders 2 makes it easier for the depalletizing device to move in each area of ​​the stacking boxes 4, and can move the depalletizing device to a site with a small space. The reciprocating movement of the second slide plate 25 and the second slide block 26 can alternately push the boxes 4 into the transfer boxes 30 in the double stations on both sides, and then the boxes 4 are alternately split and transferred to the transfer stations or processing stations on both sides through the transfer boxes 30 in the double stations on both sides. The double station operation speeds up the depalletizing of the boxes 4 and carries out subsequent processing, so that the stacking of the split boxes 4 can be quickly transferred and split, and the traditional way of transporting the depalletizing boxes 4 by clamping is changed to use a lifting method to transport the boxes 4 down, which reduces the damage to the boxes 4 caused by excessive pressure when clamping the boxes 4, and the problem of the boxes 4 falling due to insufficient pressure, optimizes the depalletizing process of the boxes 4, and enables the depalletizing device to split the stacking of the boxes 4 faster and safer.

[0034] like Figures 1 to 7 As shown, multiple transfer columns 1 are slidably connected with sliding frames 9, one side of two sliding frames 9 on one side are fixedly connected with first sliding blocks 22 through connecting blocks 23, one side of two sliding frames 9 on the other side are fixedly connected with first sliding blocks 21 through connecting blocks 23, two first sliding blocks 21 are slidably connected with the first sliding blocks 22, one side of the second sliding block 25 is slidably connected with the first sliding block 21 on one side, and one side of the second sliding block 26 is slidably connected with the first sliding block 21 on the other side.

[0035] Specifically, when pushing the top-layer box 4, the second slide 25 and the second slider 26 move to push the top-layer box 4, so that the box 4 moves within the first slide 21 and the first slider 22 on both sides, to prevent the box 4 from shifting in position and sliding out to the sides of the second slide 25 and the second slider 26 when moving, so that the top-layer box 4 can be smoothly pushed into the transfer box 30 for transfer.

[0036] like Figures 1 to 7As shown, one side of the two sliding frames 9 on one side is fixedly connected to the baffle 27 through the connecting plate 29, and one side of the two electric sliding frames 9 on the other side is fixedly connected to the baffle 28 through the connecting plate 29, and the two baffles 27 are slidably connected to the baffle 28.

[0037] Specifically, when the box body 4 on the top layer is pushed, the second slide plate 25 and the second slide block 26 push the box body 4 on the top layer to move, and the baffle plate 27 and the stopper 28 will block the movement of the box body 4 on the next layer under the top layer, preventing the lower box body 4 from moving along with the top box body 4 when the top box body is pushed, causing the entire wooden box stack to become tilted and loose, thereby ensuring that the wooden box stack is split smoothly.

[0038] like Figures 1 to 7 As shown, the first motors 7 are fixedly connected to the inner lower sides of the multiple transfer columns 1 , the first threaded rods 8 are fixedly connected to the output ends of the multiple first motors 7 , and the multiple first threaded rods 8 are slidably connected to the sliding frame 9 .

[0039] Specifically, when the box body 4 on the top layer is pushed out, the first motor 7 is started to rotate the first threaded rod 8, so that the sliding frame 9 moves downward with the second slide plate 25 and the second slider 26 to push the box body 4 on the next layer.

[0040] like Figures 1 to 7 As shown, one side of the second slide plate 25 and the second slider 26 is fixedly connected to a connecting column 24, the reciprocating device includes two moving devices, the moving device includes a second motor 13 fixedly connected in the sliding frame 9, the output end of the second motor 13 is fixedly connected to the take-up wheel 14, one side of the connecting column 24 is rotatably connected to the pulley 20, the take-up wheel 14 and the pulley 20 are connected by a steel rope 18, one end of the steel rope 18 is fixedly connected to the take-up wheel 14, and the other end of the steel rope 18 is fixedly connected to the sliding frame 9, and the steel rope 18 is movably connected to the pulley 20.

[0041] Specifically, when pushing the box body 4, the second motor 13 is started to rotate the take-up wheel 14 to wind the steel rope 18, so that the pulley 20 gradually moves toward the second motor 13 with the second slide plate 25 and the second slider 26 through the connecting column 24, so that power can be saved to move the second slide plate 25 and the second slider 26 to push the box body 4 to move, thereby reducing the power required for destacking and speeding up the efficiency of destacking the wooden box stack.

[0042] like Figures 1 to 7 As shown, the two moving devices are staggered to form a reciprocating device, and the two moving devices work alternately to make the second slide plate 25 and the second slider 26 reciprocate.

[0043] Specifically, after the second slide 25 and the second slider 26 push the box 4 to one side, the second motor 13 away from the second slide 25 and the second slider 26 is started to move the second slide 25 back and push the box 4 of the next layer again, so that the second slide 25 and the second slider 26 can be moved back and forth to gradually split and transport the wooden box stack.

[0044] Embodiment 2

[0045] like Figures 3 to 7 As shown in Comparative Example 1, another embodiment of the present invention is:

[0046] A rotating roller 36 is rotatably connected to the lower inner side of the two transfer boxes 30, a rotating plate 31 is rotatably connected to one side of the two transfer boxes 30, and a hanging device is provided on both sides of the two transfer boxes 30. The hanging device includes a clamping block 40 rotatably connected to one side of the transfer box 30, and a clamping column 39 is fixedly connected to one side of the transfer box 30.

[0047] Specifically, when the box body 4 is pushed into the transfer box 30, the rotating roller 36 will rotate to make the box body 4 move better into the transfer box 30. At this time, the block 40 is as follows: Figure 7 The clamping column 39 is shown as being clamped, so that the box body 4 in the transfer box 30 can be smoothly disassembled and transported. After the box body 4 is disassembled and transported by the transfer box 30, the rotating block 40 no longer clamps the clamping column 39, and the rotating plate 31 can be rotated to move the box body 4 in the transfer box 30 out.

[0048] like Figures 3 to 7 As shown, a rotating platform 41 is fixedly connected to one side of the transfer box 30 , a cylinder 42 is fixedly connected to one side of the rotating platform 41 , and an output end of the cylinder 42 is rotatably connected to the clamping block 40 .

[0049] Specifically, the block 40 can be rotated by starting the cylinder 42, and the cylinder 42 can also be rotated on the transfer box 30 through the rotating platform 41, that is, the block 40 can be smoothly rotated by the cylinder 42 without getting stuck on the column 39.

[0050] like Figures 3 to 7 As shown, a plurality of lifting blocks 32 are each provided with a rotating device, the rotating device comprising a third motor 33 fixedly connected in the lifting block 32, a first gear 34 fixedly connected to the output end of the third motor 33, a second gear 35 fixedly connected to one side of the transfer box 30, and the first gear 34 is meshingly connected with the second gear 35.

[0051] Specifically, when the box body 4 is taken out from the transfer box 30 , the third motor 33 is started to rotate the first gear 34 and the second gear 35 , so that the transfer box 30 can be rotated and tilted, and the box body 4 will slide out from the rotating roller 36 in the transfer box 30 .

[0052] like Figures 3 to 7As shown, the lower sides of the multiple transfer columns 1 are rotatably connected to a rotating block 5, and the multiple rotating blocks 5 are rotatably connected to rollers 6.

[0053] Specifically, when the transfer column 1 is moved to move the entire destacking device, the destacking device can be conveniently moved through the transfer column 1 to perform destacking work by rotating the roller 6 and rotating the rotating block 5 under the transfer column 1.

[0054] Working principle: Move the transfer column 1 to the side of the box 4, and place the box 4 stack on the placement seat 3. Start the hydraulic cylinder 2 to adjust the distance between the multiple transfer columns 1 so that the stack formed by the box 4 is located between the multiple transfer columns 1. Start the fourth motor 37 to rotate the second threaded rod 38. The second threaded rod 38 rotates so that the lifting block 32 can slide on the transfer column 1. The lifting block 32 moves up and down to the top layer of the box 4. The second slide plate 25 and the second slider 26 are moved by the reciprocating device to push the top layer of the box 4 into the transfer box 30. The second slider 26 can slide in the second slide plate 25 without affecting the movement of the multiple transfer columns 1 driven by the hydraulic cylinder 2. Then, the lifting block 32 is moved downward with the transfer box 30 by the fourth motor 37, and the box 4 is transferred from the stack of the placement seat 3 for processing and use. In this way, multiple hydraulic cylinders 2 can be used. The telescopic operation makes it easier for the depalletizing device to move in each stacking box 4 area, and can move the depalletizing device to a site with a small space. The boxes 4 are alternately pushed into the transfer boxes 30 in the double stations on both sides by the reciprocating movement of the second slide plate 25 and the second slide block 26, and then the boxes 4 are alternately split and transferred to the transfer stations or processing stations on both sides by the transfer boxes 30 in the double stations on both sides. The depalletizing of the boxes 4 and subsequent processing are accelerated by the double station operation, so that the stacking of the split boxes 4 can be quickly transferred and split. In addition, the traditional method of carrying the depalletizing boxes 4 by clamping is changed, and the boxes 4 are transported down by lifting, which reduces the problem of damage to the boxes 4 caused by excessive pressure when clamping the boxes 4, and the problem of the boxes 4 falling due to insufficient pressure, optimizes the depalletizing process of the boxes 4, and enables the depalletizing device to split the stacking of the boxes 4 faster and safer.

[0055] When the top box body 4 is pushed, the second slide plate 25 and the second slide block 26 move to push the top box body 4, so that the box body 4 moves in the first slide plates 21 and the first slide block 22 on both sides, preventing the box body 4 from shifting in position and sliding out to the two sides of the second slide plate 25 and the second slide block 26 when moving, so that the top box body 4 can be smoothly pushed into the transfer box 30 for transportation; when the top box body 4 is pushed, the second slide plate 25 and the second slide block 26 push the top box body 4 to move, and the baffle plate 27 and the stopper 28 will block the movement of the box body 4 of the next layer of the top layer, preventing the lower box body 4 from moving when the top box body 4 is pushed, so that the entire wooden box stack body is tilted and loose, thereby ensuring that the wooden box stack body is split smoothly; when the top box body 4 is pushed out, the first motor 7 is started to rotate the first threaded rod 8, so that the slide The movable frame 9 moves the second slide plate 25 and the second slider 26 downward to push the box body 4 of the next layer; when pushing the box body 4, the second motor 13 is started to rotate the take-up wheel 14 to wind the steel rope 18, so that the pulley 20 gradually moves toward the second motor 13 with the second slide plate 25 and the second slider 26 through the connecting column 24, so that power can be saved to move the second slide plate 25 and the second slider 26 to push the box body 4 to move, reduce the power required for destacking and speed up the efficiency of splitting the wooden box stack; when the second slide plate 25 and the second slider 26 push the box body 4 to one side, the second motor 13 away from the second slide plate 25 and the second slider 26 is started to move the second slide plate 25 back to push the box body 4 of the next layer again, so that the second slide plate 25 and the second slider 26 can be reciprocated to push the wooden box stack to be gradually split and transported;

[0056] When the box body 4 is pushed into the transfer box 30, the rotating roller 36 will rotate to make the box body 4 move better into the transfer box 30. At this time, the block 40 is as shown in FIG. Figure 7 The stuck column 39 is shown, so that the box body 4 in the transfer box 30 can be smoothly disassembled and transported. When the box body 4 is disassembled and transported by the transfer box 30, the rotating block 40 no longer jams the column 39, and the rotating plate 31 can be rotated to move the box body 4 in the transfer box 30 out; starting the cylinder 42 can make the block 40 rotate, and the cylinder 42 can also be rotated on the transfer box 30 through the rotating table 41, that is, the block 40 can be smoothly rotated by the cylinder 42 and no longer jammed with the column 39; when the box body 4 is taken out of the transfer box 30, the third motor 33 is started to rotate the first gear 34 and drive the second gear 35 to rotate, so that the transfer box 30 can be rotated and tilted, and the box body 4 will slide out from the rotating roller 36 in the transfer box 30; when moving the transfer column 1 to move the entire destacking device, the roller 6 rotates and can be rotated under the transfer column 1 through the rotating block 5, so that the destacking device can be conveniently moved through the transfer column 1 to perform destacking work.
