Description

Technical Field

[0001] This invention belongs to the technical field of conveyor equipment, specifically relating to a vertical lifting and steering device for a skid conveyor. Background Technology

[0002] With the development of industrial modernization, the demand for automated conveyors is increasing in industries such as automobile manufacturing. Conveying systems are often needed to improve the modernization of manufacturing processes. Using skid conveyors in automobile manufacturing processes such as painting, final assembly, and welding can meet certain special needs of the automotive industry. Their characteristics and advantages are irreplaceable by plate conveyors and accumulating chain conveyors. Existing skid conveyor technologies generally use pneumatic or hydraulic lifting structures, which have the drawback of poor performance and stability. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing a vertical lifting and steering device for a skid conveyor. The device uses a lifting assembly consisting of a motor-driven cam rotation to achieve the lifting and lowering of the conveyor, thereby improving its holding performance and stability.

[0004] This invention is achieved through the following technical solution.

[0005] A vertical lifting and steering device for a skid conveyor includes an outer conveyor and an inner conveyor with perpendicular conveying directions. The outer conveyor is fixedly mounted on an outer conveyor base, and an outer conveyor drive motor is fixedly mounted on one side of the outer conveyor base, driving the outer conveyor drive shaft. The inner conveyor is fixedly mounted on a lifting frame, and an inner conveyor drive motor is fixedly mounted on one side of the lifting frame, driving the inner conveyor drive shaft. The device is characterized in that: the lower part of the lifting frame is mounted on a cam mechanism on the lifting frame base; the lifting frame base is provided with two sets of bearing brackets, each set of two bearing brackets mounting a horizontal lifting drive shaft via bearings, and the two lifting drive shafts are parallel to each other. Each lifting drive shaft has a cam mechanism connected to both ends. The cam of each cam mechanism is installed in a cam frame on the inner side of the lower part of the lifting frame. The cam frame consists of two parallel baffles and a vertical plate connecting the two baffles. A cam pad is provided between the baffle and the cam on the upper part of the cam frame. A lifting drive motor for driving the two lifting drive shafts is provided in the middle of the lifting frame base. A V-shaped guide wheel mounting plate is fixedly installed on both sides of the lifting frame base between the two lifting drive shafts. An axially horizontal guide wheel is installed on each of the two outer sides of the guide wheel mounting plate. Two V-shaped guide plates are installed on the lifting frame. The two outer sides of each V-shaped guide plate abut against the two guide wheels on the guide wheel mounting plate on the same side.

[0006] Furthermore, the outer conveyor drive motor and the outer conveyor drive shaft, and the inner conveyor drive motor and the inner conveyor drive shaft are connected by gears and chains.

[0007] Furthermore, the mounting shafts of the two guide wheels on the guide wheel mounting plate are located in the same horizontal plane and are perpendicular to each other.

[0008] Furthermore, a proximity switch is installed on the base of the lifting frame.

[0009] The beneficial effects of this invention are: 1. By using a motor to drive four cam mechanisms to rotate on the base of the lifting frame to push the lifting frame up and down, the holding performance and stability during the lifting process are improved compared with traditional pneumatic or hydraulic lifting structures; 2. By setting guide wheels and guide plates, the lifting frame can be vertically raised or lowered during the lifting or lowering process of the cam mechanism; 3. Rolling friction is used between the cam and the cam frame, as well as between the guide wheel and the guide plate, reducing component wear during lifting; 4. A pad is provided inside the cam frame, which can be replaced periodically as a consumable part, reducing the maintenance cost of the equipment. Attached Figure Description

[0014] The invention will be further illustrated below with reference to specific examples and accompanying drawings.

[0015] like Figure 1-3As shown, the vertical lifting and steering device of the skid conveyor includes an outer conveyor 2 and an inner conveyor 5 with mutually perpendicular conveying directions. The outer conveyor 2 is fixedly installed on the outer conveyor base 1, and an outer conveyor drive motor 21 is fixedly installed on one side of the outer conveyor base 1, driving the outer conveyor drive shaft 22 of the outer conveyor 2. The inner conveyor 5 is fixedly installed on the lifting frame 4, and an inner conveyor drive motor 51 is fixedly installed on one side of the lifting frame 4, driving the inner conveyor drive shaft 52 of the inner conveyor 5. The lower part of the lifting frame 4 is mounted on a cam mechanism on the lifting frame base 3. The lifting frame base 3 is provided with two sets of bearing frames 31, and each set of two bearing frames 31 is connected by bearings to mount a horizontal lifting drive shaft 32. The two lifting drive shafts 32 are parallel to each other. A cam mechanism is connected to each end of the lifting drive shaft 32. The cam 33 of each cam mechanism is installed in the cam frame 41 on the lower inner side of the lifting frame 4. The cam frame 41 is composed of two parallel baffles and a vertical plate connecting the two baffles. A cam pad 42 is provided between the baffle on the upper part of the cam frame 41 and the cam 33. A lifting drive motor 34 for driving the two lifting drive shafts 32 is provided in the middle of the lifting frame base 3. A V-shaped guide wheel mounting plate 35 is fixedly installed on both sides of the lifting frame base 3 between the two lifting drive shafts 32. An axially horizontal guide wheel 36 is installed on each of the two outer sides of the guide wheel mounting plate 35. Two V-shaped guide plates 43 are installed on the lifting frame 4. The two outer sides of each V-shaped guide plate 43 abut against the two guide wheels 36 on the guide wheel mounting plate 35 on the same side.

[0016] The outer conveyor drive motor 21 and the outer conveyor drive shaft 22, and the inner conveyor drive motor 51 and the inner conveyor drive shaft 52 are connected by gears and chains.

[0017] The mounting shafts of the two guide wheels 36 on the guide wheel mounting plate 35 are located in the same horizontal plane and are perpendicular to each other.

[0018] A proximity switch 37 is installed on the base 3 of the lifting frame.

[0019] When the present invention is in use: when the proximity switch 37 on the lifting frame base 3 receives the sensing signal, the lifting drive motor 34 starts, driving the lifting drive shaft 32 to rotate, and the four cam mechanisms also rotate accordingly. The cam 33 of the cam mechanism pushes the cam frame 41 of the lifting frame 4 upward. At the same time, due to the action of the guide wheel 36 and the V-shaped guide plate 43, the guide wheel 36 clamps the guide plate 43, so that the lifting frame 4 rises vertically as a whole. The inner conveyor drive motor 51 on the lifting frame 4 rotates, and the inner conveyor 5 rises to a certain height with the lifting frame 4, receiving the products conveyed by the outer conveyor 2 to achieve conveying and turning.

Any changes, substitutions, combinations, simplifications, modifications, etc., made by those skilled in the art without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
