Cylinder body 2 49 is provided with a long hole for allowing the restriction cloth 2 53 to pass through.

[0038] In this embodiment, Figure 3 、 Figure 6 、 Figure 7 As shown, motor twelve 52 is fixedly connected to both sides of the inner cavity of cylinder one 48, and the output end of motor twelve 52 is fixedly connected to one end of roller one 51. One end of the inner cavity of cylinder two 49 is fixedly connected to motor thirteen 54, and the output end of motor thirteen 54 is fixedly connected to one end of roller two 55.

[0039] A clamping block 1 5 is fixedly connected to one side of the upper end surface of the work station plate 2 , a cylinder 46 is fixedly connected to one side of the upper end surface of the work station plate 2 , and a clamping block 2 47 is fixedly connected to the piston end of the cylinder 46 .

[0040] One end of the pillar 16 is threadedly connected to a threaded rod 15, and both ends of the threaded rod 15 are rotatably set on the mounting plate 6. One side of the mounting plate 6 is fixedly connected to a motor 2 14, and the output end of the motor 2 14 is fixedly connected to one end of the threaded rod 15.

[0041] Specifically, the existing palletizing device realizes the palletizing operation by clamping the tires through the clamping structure when in use. However, when the tires need to be stacked on the pallet, since the pallet is flat, the tires at the edge of the pallet are more likely to be accidentally touched when the tires are stacked on the pallet, resulting in the situation of tipping over, thereby affecting the normal progress of the palletizing work. Therefore, in order to solve the above problem, when the present embodiment is in use, the pallet is placed on the station plate 2, and one corner of the pallet is in contact with the clamping block 5, and then the cylinder 46 is used to press the pallet. Drive the clamping block 2 47 to move, and the clamping block 2 47 contacts the other corner of the pallet, and the pallet can be fixed with the cooperation of the clamping block 1 5 and the clamping block 2 47. Since the clamping block 1 5 is under the cylinder 1 48 and the two are aligned, the cylinder 1 48 is aligned with one corner of the pallet, and then the motor 2 14 drives the threaded rod 15 to rotate, so that the support 16 slides downward until the bottom of the cylinder 1 48, the cylinder 2 49, and the cylinder 3 50 are in contact with the upper surface of the pallet, and then the electric push rods 32 on both sides are started respectively according to the size of the pallet. The movable cylinder 2 49 moves to adjust the distance between the cylinder 1 48 and the cylinder 2 49. At the same time, the telescopic rod 31 is synchronously extended and retracted. The roller 1 51 and the roller 2 55 are also rotated under the action of the motor 12 52 and the motor 13 54 respectively, and the restriction cloth 1 8 and the restriction cloth 2 53 are unwound, so that the portions of the restriction cloth 1 8 and the restriction cloth 2 53 exposed to the outside are always kept tight, until the cylinder 1 48, the cylinder 2 49 and the cylinder 3 50 are all aligned with the four corners of the pallet. At this time, the restriction cloth 1 8 and the restriction cloth 2 53 form a barrier around the edge of the pallet. Then, the robot arm 3 and the pneumatic gripper 4 are used to clamp the tires on the production line and place them on the pallet for palletizing. Since there are multiple workstations 2, multi-station palletizing can be performed simultaneously, which is beneficial to improving palletizing efficiency. During the entire palletizing process, the tires at the edge of the pallet will contact and be blocked by the limiting cloth 1 8 and the limiting cloth 2 53, thereby effectively avoiding the tires at the edge of the pallet from being accidentally touched when being stacked on the pallet, and then tipping over, thereby ensuring the normal progress of the palletizing work.

One side of the inner cavity of the plate body 13 is fixedly connected to a motor 5 22, and the output end of the motor 5 22 is fixedly connected to one end of the threaded rod 7 45.

[0046] Specifically, in the above embodiment, although the restriction cloth 1 8 and the restriction cloth 2 53 can be used to form a barrier at the edge of the pallet to prevent the tire from falling, during the palletizing process, there is still some redundant space in the range of the barrier formed by the restriction cloth 1 8 and the restriction cloth 2 53. Therefore, the tire may still fall into the redundant space in the barrier range due to external force, which still affects the normal palletizing process.Therefore, in order to avoid the above problems, when the present embodiment is in use, after the restriction cloth 1 8 and the restriction cloth 2 53 form a barrier at the edge of the pallet, the distance between the two plate bodies 13 can be adjusted according to the diameter of the tire by driving the bidirectional threaded rod 26 to rotate by the motor 7 25, and the distance can be equal to the diameter of the tire. Then, the motor 6 23 drives the threaded rod 3 24 to rotate, so as to drive the groove plate 27 to descend until the bottom of the plate body 13 and the plate body 2 30 contact the surface of the pallet. Then, the motor 5 22 drives the threaded rod 7 45 to rotate, so that the plate body 2 30 slides on the inner side of the plate body 13 until the end of the plate body 13 contacts the surface of the restriction cloth 2 53. At this time, the plate body 13 and the plate body 2 are in contact with the surface of the pallet. The plate body 2 30, the restriction cloth 1 8, and the restriction cloth 2 53 cooperate with each other to form a rectangular placement channel, and then the motor 3 18 drives the gear 2 19 to rotate, so that the rack 2 12 drops, and the expansion plate 35 extends into the rectangular placement channel. Subsequently, according to the diameter of the tire, the displacement ring 34 is driven to move by the motor 11 44 to drive the threaded rod 6 43 to rotate, and the displacement ring 34 drives the adjustment rod 57 to slide on the connecting ring 33 through the transmission rod 56, so that multiple expansion plates 35 are simultaneously away from the axis of the connecting ring 33, the elastic pad 36 is deformed, and the distance between the expansion plate 35 and the axis of the connecting ring 33 is equal to the radius of the tire. The expansion plate 35 and the elastic pad 36 cooperate with each other to form a The cylindrical channel matches the tire size. When stacking, the pneumatic clamp 4 places the tire above the cylindrical channel, and then the pneumatic clamp 4 releases the tire, and the tire falls into the cylindrical channel. Repeat the above operation until the tire in the cylindrical channel reaches a certain height, and then drive the connecting ring 33 to rise, so that the tire is out of the cylindrical channel, and then drive the rack 7 to slide by driving the gear 10 to rotate by the motor 9, then the position of the connecting ring 33 can be adjusted to move the connecting ring 33 to the redundant space of the rectangular placement channel by a distance of the tire diameter, and the expansion plate 35 and the elastic pad 36 will have a blocking effect on the tire that has been placed, and then repeat the above operation until the rectangular placement channel is full. After the pallet is fully loaded with tires, motor eight 28 drives threaded rod four 29 to rotate, and motor four 21 drives threaded rod two 20 to rotate, driving displacement plate 17 and slider 11 to move horizontally to stack another row of tires. The already stacked row of tires will be restricted by plate one 13, plate two 30, restriction cloth one 8, and restriction cloth two 53, and will not fall into the redundant space of the pallet. Adjacent tires will also resist each other until a sufficient number of tires are stacked on the pallet. Therefore, during the tire stacking process, the already placed tires can be restricted in multiple directions, preventing the tires from falling into the redundant space of the pallet due to external forces, thereby affecting the normal stacking process.

[0047] In this embodiment, Figure 9 and Figure 10As shown, the expansion plate 35 is also provided with an anti-deflection component; the anti-deflection component includes a slide rod 39 fixedly connected to both ends of the slide groove of the expansion plate 35 on both sides, the slide rod 39 is slidably connected to the lifting block 38, and a support block 40 is rotatably provided at one end of the lifting block 38.

[0048] One side of the lifting block 38 is threadedly connected to a threaded rod 5 42, and both ends of the threaded rod 5 42 are rotatably set on the expansion plate 35. One side of the upper end of the expansion plate 35 is fixedly connected to a motor 9 37, and the output end of the motor 9 37 is fixedly connected to one end of the threaded rod 5 42. One end of the lifting block 38 is fixedly connected to a motor 10 41, and the output end of the motor 10 41 is fixedly connected to one end of the support block 40.

[0049] Specifically, in the above embodiment, when the pneumatic gripper 4 releases the tire, the tire will fall into the cylindrical channel composed of the expansion plate 35 and the elastic pad 36 for stacking. However, during the falling process of the tire, the tire may deflect, causing the tire to lean on the expansion plate 35 or the elastic pad 36, affecting the subsequent stacking of tires, and the pneumatic gripper 4 is not easy to enter the cylindrical channel. Therefore, in order to solve this problem, when the pneumatic gripper 4 drives the tire to move to the upper edge of the expansion plate 35, the motor The ten 41 drives the support block 40 to rotate, so that the support block 40 extends from the groove of the expansion plate 35. After the pneumatic clamp 4 releases the tire, the tire will be supported by the support block 40, and then the motor nine 37 drives the threaded rod five 42 to rotate, so that the support block 40 drives the tire to descend. When the tire falls to a suitable height, the support block 40 is rotated into the groove again, and the tire will fall smoothly, thereby avoiding the tire deflection during the falling process, causing the tire to lean on the expansion plate 35 or the elastic pad 36, thereby affecting the subsequent stacking work of the tire.

[0050] Working principle: Place the pallet on the work station plate 2, and one corner of the pallet fits with the clamping block 1 5, then the cylinder 46 drives the clamping block 2 47 to move, and the clamping block 2 47 contacts the other corner of the pallet, and the pallet can be fixed with the cooperation of the clamping block 1 5 and the clamping block 2 47. Since the clamping block 1 5 is under the cylinder 1 48 and the two are aligned, the cylinder 1 48 is aligned with one corner of the pallet, and then the motor 2 14 drives the threaded rod 1 15 to rotate, so that the support 16 slides downward until the bottom of the cylinder 1 48, the cylinder 2 49, and the cylinder 3 50 fit the upper surface of the pallet, and then according to the size of the pallet, the electric push rods 32 on both sides are started respectively, and the electric push rods 32 drive the cylinder 2 49 to move, and adjust the distance between the cylinder 1 48 and the cylinder 2 49. At the same time, the telescopic rod 31 is synchronously extended and retracted, and the roller 1 51 and the roller 2 55 are also respectively driven by the motor 12 52 and the motor 13 5 4 rotates to unwind the restriction cloth 1 8 and the restriction cloth 2 53, so that the parts of the restriction cloth 1 8 and the restriction cloth 2 53 exposed to the outside are always kept tight until the cylinder 1 48, the cylinder 2 49 and the cylinder 3 50 are all aligned with the four corners of the pallet. At this time, the restriction cloth 1 8 and the restriction cloth 2 53 form a barrier around the edge of the pallet. Then the robot arm 3 and the pneumatic gripper 4 are used to clamp the tires on the production line and place the tires on the pallet for palletizing. Since there are multiple workstations 2, multi-station palletizing can be carried out at the same time, which is conducive to improving palletizing efficiency. During the entire palletizing process, the tires at the edge of the pallet will contact the restriction cloth 1 8 and the restriction cloth 2 53 and be blocked, thereby effectively avoiding the situation where the tires at the edge of the pallet are accidentally touched when being stacked on the pallet, and then tipping over, thereby ensuring the normal progress of the palletizing work.After the restriction cloth 1 8 and the restriction cloth 2 53 form a barrier at the edge of the pallet, the distance between the two plate bodies 13 can be adjusted according to the diameter of the tire by driving the bidirectional threaded rod 26 to rotate by the motor 7 25, and the distance can be equal to the diameter of the tire. Then, the motor 6 23 drives the threaded rod 3 24 to rotate to drive the groove plate 27 down until the bottom of the plate body 13 and the plate body 2 30 contact the surface of the pallet. Then, the motor 5 22 drives the threaded rod 7 45 to rotate to make the plate body 2 30 slide on the inside of the plate body 13 until the end of the plate body 13 contacts the surface of the restriction cloth 2 53. At this time, the plate body 13, the plate body 2 30, the restriction cloth 1 8, and the restriction cloth 2 53 cooperate with each other to form a rectangular placement channel, and then the motor three 18 drives the gear two 19 to rotate, so that the rack two 12 drops, and the expansion plate 35 extends into the rectangular placement channel. Subsequently, according to the diameter of the tire, the displacement ring 34 is driven to move by the motor eleven 44 to drive the threaded rod six 43 to rotate. The displacement ring 34 drives the adjustment rod 57 to slide on the connecting ring 33 through the transmission rod 56, so that multiple expansion plates 35 are simultaneously away from the axis of the connecting ring 33, and the elastic pad 36 is deformed. The distance between the expansion plate 35 and the axis of the connecting ring 33 is equal to the radius of the tire. The expansion plate 35 and the elastic pad 36 cooperate with each other to form a cylinder that matches the size of the tire. When stacking, the pneumatic clamp 4 places the tire above the cylindrical channel, and then the pneumatic clamp 4 releases the tire, and the tire falls into the cylindrical channel. The above operation is repeated until the tire in the cylindrical channel reaches a certain height, and then the connecting ring 33 is driven to rise, so that the tire is separated from the cylindrical channel, and then the motor 9 drives the gear 10 to rotate to drive the rack 7 to slide, and the position of the connecting ring 33 can be adjusted to move the connecting ring 33 to the redundant space of the rectangular placement channel by a tire diameter, and the expansion plate 35 and the elastic pad 36 will have a blocking effect on the tire that has been placed, and then the above operation is repeated until the rectangular placement channel is full of tires. Then, the motor 8 28 drives the threaded rod 4 29 to rotate, and the motor 4 21 drives the threaded rod 20 to rotate, thereby driving the displacement plate 17 and the slider 11 to move horizontally to stack another row of tires. The tires in the row that have been stacked will be limited by the plate 1 13, the plate 2 30, the limiting cloth 1 8, and the limiting cloth 2 53, and will not fall to the redundant space of the pallet. The adjacent tires will also resist each other until a sufficient number of tires are stacked on the pallet. In this way, during the tire stacking process, the tires that have been placed can be limited in multiple directions, thereby preventing the tires from falling to the redundant space of the pallet due to external forces, thereby affecting the normal stacking work.When the pneumatic gripper 4 drives the tire to the upper edge of the expansion plate 35, the motor 10 41 drives the support block 40 to rotate, causing the support block 40 to extend from the groove of the expansion plate 35. After the pneumatic gripper 4 releases the tire, the tire is supported by the support block 40. Then, the motor 9 37 drives the threaded rod 5 42 to rotate, causing the support block 40 to lower the tire. When the tire drops to the appropriate height, the support block 40 rotates back into the groove, and the tire falls smoothly. This prevents the tire from leaning against the expansion plate 35 or the elastic pad 36 due to tire deflection during the falling process, thereby affecting the subsequent tire stacking work.
