Description

Technical Field

[0001] The invention relates to the technical field of tire destacking, and in particular to an automatic tire destacking device. Background Art

[0002] The existing tire destacking device uses a fixed frame tire holding device, which is designed to have a height of five tire groups. A tire clamping device is designed on the fixed frame at the position of the second tire group (counting from the bottom to the top), and a small lifting platform (lifting height 50MM) is designed on the rolling bed. Each time the tire passes through the clamping device, the bottom tire is placed on the small lifting platform. Then the lifting platform rises, the clamping device is released, and the bottom tire is placed on the lifting platform; the lifting platform descends again, and the tire is placed on the rolling bed and flows away; this cycle is repeated to achieve the destacking of five tire groups.

[0003] However, the existing tire destacking device has the following defects: because it rotates between the fixed frame tire holding device and the rolling bed through a small lifting platform, it can only hold five sets of tires at a time, the production cycle is less than 30 JPH, and the destacking efficiency is low. Therefore, it is necessary to design an automatic tire destacking device to improve the destacking efficiency. Summary of the invention

[0004] In view of the defects in the prior art, the object of the present invention is to provide an automatic tire destacking device, which can improve the destacking efficiency, thereby improving production efficiency and saving labor.

[0005] To achieve the above-mentioned purpose, the present invention provides an automatic tire destacking device, comprising a fixed frame, a lifting mechanism is arranged in the middle of the fixed frame, a lifting roller bed is arranged on the lifting mechanism, a tire holding mechanism and an auxiliary fixing mechanism are arranged above the lifting roller bed, and the tire holding mechanism and the auxiliary fixing mechanism cooperate to clamp and fix the tire;

[0006] The lifting roller bed is provided with docking roller beds at both ends of the tire transmission direction. The lifting roller bed can drive the tire to move up and down under the drive of the lifting mechanism to realize transmission and transportation in coordination with the docking roller beds.

[0007] As a preferred embodiment, a bracket is provided on the fixed frame, vertical slide rails are provided on both sides of the bracket, and the lifting mechanism can move up and down along the vertical slide rails.

[0008] As a preferred embodiment, the lifting mechanism includes an L-shaped lifting frame and a lifting motor, the lifting roller bed is installed on the lifting frame, and the lifting motor is used to drive the lifting frame to drive the lifting roller bed to move up and down.

[0009] As a preferred embodiment, a crossbeam is provided on the fixed frame, two shaft sleeves are symmetrically provided on the crossbeam, and the tire clamping mechanism is installed on the shaft sleeve and can be rotatably clamped or loosened.

[0010] As a preferred embodiment, the tire holding mechanism includes a clamping gripper, a connecting rod and a tire holding cylinder. The clamping gripper is transmission-connected to one end of the connecting rod, and the other end of the connecting rod is transmission-connected to the tire holding cylinder. The tire holding cylinder can drive the connecting rod to extend and retract to drive the clamping gripper to rotate, clamp or release.

[0011] As a preferred embodiment, a horizontal slide rail is provided on the rear side of the cross beam, and the piston rod device of the tire holding cylinder can run forward and backward along the horizontal slide rail to drive the connecting rod to extend and retract.

[0012] As a preferred embodiment, the auxiliary fixing mechanism includes two rows of roller groups, and the two rows of roller groups are symmetrically arranged on the crossbeam.

[0013] As a preferred implementation, a lifting sensor group is arranged on the bracket, and the lifting sensor group is used to control the lifting working position of the lifting mechanism.

[0014] As a preferred implementation, the lifting sensor group includes a plurality of photoelectric proximity switches and limit switches.

[0015] As a preferred implementation, a block is provided on the lifting mechanism, and the block is used to block the trigger signal of the photoelectric proximity switch.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] Firstly, the traditional tire holding device places the tire on a small lifting platform, and then places the tire on a roller bed for transportation through the small lifting platform. However, the present invention directly installs the lifting roller bed on the lifting device, and directly places the tire on the lifting roller bed for lifting and transportation through the tire holding clamping mechanism. It does not use a separate small lifting platform and roller bed for transition, and has one less intermediate link, which greatly improves the efficiency of tire removal, and increases the production capacity from 30JPH to 60JPH, thereby improving the beat.

[0018] Secondly, the lifting height of the present invention is controlled by a sensor group, the height is adjustable, and it has flexibility, and the roller bed docking accuracy is higher.

[0019] Thirdly, the tire holding mechanism of the present invention adopts a four-point "clamp-type" clamping and releasing method, rather than a traditional clamping method, so that the clamping state is more stable and reliable.

[0020] Fourthly, the present invention solves the problem of destacking various tire models without being subject to other restrictions and the number of tires to be destackered is not limited, and the present invention can be widely promoted and applied.

[0021] Fifthly, the present invention solves the problem of automatically destacking the stacked tires delivered by suppliers, quickly entering the tire line of the factory, and transporting them to designated workstations for tire assembly, thereby improving production efficiency and saving labor.

When the lifting roller 3 is connected with the docking roller 6, the tire is driven to move forward.

[0029] The fixed frame 1 is provided with a bracket 7, which is welded and mounted on the column of the fixed frame. Vertical slide rails 8 are arranged on both sides of the bracket 7, and the lifting mechanism 2 can move up and down along the vertical slide rails 8. The lifting mechanism 2 includes an L-shaped lifting frame 201 and a lifting motor 202. The lifting roller bed 3 is installed on the lifting frame 201, and the lifting motor 202 is used to drive the lifting frame 201 to drive the lifting roller bed 3 to move up and down.

[0030] A crossbeam 9 is arranged on the fixed frame 1, and two shaft sleeves 10 are symmetrically arranged on the crossbeam 9. The two shaft sleeves 10 are arranged symmetrically in the center, and the two shaft sleeves 10 are welded to the crossbeam 9. The tire holding mechanism 4 is installed on the shaft sleeves 10 by the symmetric axes on both sides, and can be rotated to clamp or loosen. The tire holding mechanism 4 includes a clamping gripper 401, a connecting rod 402 and a tire holding cylinder 403. The connecting rods are installed on both sides of the clamping gripper 401 by the pin 14. The clamping gripper 401 is connected to one end of the connecting rod 402 by transmission, and the other end of the connecting rod 402 is connected to the cylinder piston rod device of the tire holding cylinder 403 and is connected to the tire holding cylinder 403 by transmission; the tire holding cylinder 403 can drive the connecting rod 402 to extend and retract to drive the clamping gripper 401 to rotate, clamp or loosen, and the tire holding mechanism adopts a four-point "clamp type" clamping and loosening. A horizontal slide rail 11 is arranged at the rear side of the crossbeam 9, and the piston rod device of the tire holding cylinder 403 can move forward and backward along the horizontal slide rail 11, driving the connecting rod 402 to extend and retract. When the tire holding cylinder is actuated, the piston rod device of the active cylinder moves forward and backward along the horizontal slide rail, driving the connecting rod to extend and retract, and the connecting rod drives the clamping gripper to expand and relax, thereby clamping and loosening the tire.

When the block 13 shines on the top group, the lifting device first drives the five tire groups including 4 main tires and 1 spare tire to lift to the highest working position, that is, the tire clamping mechanism just clamps to the second tire position from the top, and at this time, the tire clamping mechanism changes from a loose state to a clamped state. The first tire falls on the lifting roller bed, and then the lifting roller bed moves down to the lowest workstation. After it reaches the position, it is aligned with the front and rear docking roller beds, and the tire flows out, and the next cycle begins.

[0032] The automatic tire destacking device of the present invention realizes automatic destacking including the following process:

[0033] (1) First, 5 sets of tires flow from the front roller bed to the lifting roller bed. The lifting roller bed is equipped with an in-place proximity switch to stop at the exact position.

[0034] (2) After receiving the arrival signal, the lifting roller bed drives the 5 sets of tires to the highest working position. After receiving the signal, the tire clamping mechanism changes from the loose state to the clamping state and clamps the second tire.

[0035] (3) Then the lifting roller bed with the first tire descends to the lowest working position, and connects to the front and rear docking roller beds. After reaching the position, the lifting roller bed rotates, and the tire flows to the next docking roller bed. At this time, the tire clamping mechanism clamps the second tire, and the third, fourth, and fifth tires are stacked on the second tire.

[0036] (4) After the lifting roller bed is empty, it rises to the middle working position again, and the tire clamping mechanism changes from the clamping state to the loose state, and the tire is placed on the lifting roller bed. The lifting roller bed with the remaining 4 tires rises to the highest working position again, clamps the second tire, and continues to destacking. This cycle repeats until the destacking is completed, and then the next group of tire destacking cycles begins. During this period, the destacking speed can be adjusted by variable frequency.

[0037] The above describes the specific embodiments of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the present invention.
