Description

Technical Field

[0001] This invention relates to the field of profile steel processing technology, and in particular to a feeding device. Background Technology

[0002] The processing of curved steel involves multiple steps such as bending and welding end plates. The first step before each step is to transfer the steel from the previous step or storage station to the device that performs the current step, which is called loading. Currently, loading is usually achieved in the following ways: the first is to use a robotic arm to grip the steel, the second is to use an overhead crane to hoist it, and the third is to use manual labor to push the steel on a non-powered roller.

[0003] While robotic grippers can automate material handling, they are only suitable for shorter steel sections and require complex programming, limiting their range of motion. Using overhead cranes for hoisting and manually pushing steel sections onto unpowered rollers both require human intervention, making automation and efficient production difficult.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0025] The present application provides a feeding device, which is mainly used for material feeding, such as material transfer between processes in the process of section steel processing, and of course can also be used for the transfer of other materials involving multiple processes. The feeding device has the functions of moving the material, clamping the material and automatically feeding the material. The feeding device in the present application will be described in detail below taking arc-shaped steel as an example.

[0026] Figures 1-4 The feeding device in one embodiment of the present application is shown, which includes a rack 1, a material table 2, a walking mechanism 3, a clamping mechanism 4 and a lifting mechanism 5. The rack 1 is a mounting base, the walking mechanism 3 is installed on the rack 1, the material table 2 is connected with the output end of the walking mechanism 3 and is used for placing arc-shaped steel, the walking mechanism 3 is configured to move the material table 2, the starting and ending ends of the walking route of the material table 2 are connected with a previous process (the previous process can refer to a previous processing process or an arc-shaped steel storage station) and a next process respectively, the clamping mechanism 4 is arranged on the material table 2 and is used for clamping and fixing the arc-shaped steel on the material table 2 during the walking of the walking mechanism 3, the clamping mechanism 4 includes a first state of clamping the arc-shaped steel and a second state of releasing the arc-shaped steel, and the lifting mechanism 5 can tilt and lift the material table 2. When the clamping mechanism 4 is in the second state, the arc-shaped steel on the material table 2 can automatically separate from the tilted material table 2 under the action of its own gravity to fall into the next process.

[0027] The feeding device in the present embodiment drives the arc-shaped steel to transfer between different processes through the walking mechanism 3, fixes the arc-shaped steel during walking through the clamping mechanism 4 to prevent the arc-shaped steel from falling, and the setting of the lifting mechanism 5 can automatically fall into the next process by the gravity of the arc-shaped steel when the arc-shaped steel moves to the next process, thereby realizing automatic feeding. It should be emphasized that the lifting mechanism 5 and the walking mechanism 3 do not interfere with each other, that is, the material table 2 can be tilted during walking with the walking mechanism 3, and the synchronous operation of the lifting mechanism 5 and the walking mechanism 3 can improve the feeding efficiency; and the setting of the lifting mechanism 5 can also be used for the transfer of the arc-shaped steel between two processes with a height difference, so that the application range of the feeding device is wider.

[0028] Compared with the inclination of the material table 2 itself, it is obvious that the inclination of the walking mechanism 3 connected with the material table 2 can expand the lifting height of the material table 2, so that the arc-shaped steel can be quickly dropped to the next process, and the two processes with greater height difference can be connected. Therefore, the inclination of the material table 2 is indirectly realized by the inclination of the walking mechanism 3, that is, the lifting mechanism 5 is connected with the walking mechanism 3, and the walking mechanism 3 is tilted to the next process direction.

[0029] Reference Figure 1 and Figure 2 As shown in the figure, the lifting mechanism 5 includes a support frame 51, a clamping block 52, and a lifting driving part 53, wherein the support frame 51 serves as the installation basis of the walking mechanism 3, the walking mechanism 3 is integrally installed on the support frame 51, one end of the clamping block 52 is rotationally connected with the rack 1, and the other end is rotationally connected with the support frame 51, and the lifting driving part 53 is configured to drive the support frame 51 to tilt and lift. Specifically, a plurality of vertical seat bearings 54 are arranged on the rack 1 in a direction perpendicular to the direction of the arc-shaped steel, the clamping block 52 is fixed on the swing shaft 55 inserted in the vertical seat bearing 54, and end covers are installed at both ends of the swing shaft 55 to prevent axial movement of the swing shaft 55; the lifting driving part 53 is selected from a gas cylinder or an oil cylinder, and in this embodiment, considering that the stress on the support frame 51 does not need to be too large, the lifting driving part 53 is a gas cylinder, the output end of the gas cylinder is provided with a fish-eye joint, the fish-eye joint is connected with a fish-eye joint connecting seat arranged at the bottom of the support frame 51 through a fish-eye joint pin shaft, and the fixed end of the gas cylinder is hingedly connected with the rack 1 through a hinge seat. By driving the gas cylinder, the support frame 51 is tilted and lifted.

[0030] In addition, the lifting mechanism 5 further includes a limiting support 56 and a bump stop 57 arranged on the top of the limiting support 56, the limiting support 56 is installed on the rack 1 and used to support the support frame 51 when it is kept horizontal, and the bump stop 57 can provide buffering when the support frame 51 abuts against the limiting support 56, so as to avoid damage to the support frame 51 caused by excessive speed of the lifting mechanism 5. Exemplarily, the bump stop 57 can be made of rubber.

[0031] The walking mechanism 3 in the embodiment adopts a chain wheel and chain transmission structure. Specifically, the walking mechanism 3 comprises a driving chain wheel 31, a driven chain wheel 32, a chain 33, slide rails 34 and a rotary driving member 35. The chain wheel shaft of the driving chain wheel 31 is rotatably connected with the support frame 51 through a diamond-shaped bearing fixed on the support frame 51. In order to prevent the driving chain wheel 31 from axially moving along the chain wheel shaft, positioning sleeves are installed at the two ends of the driving chain wheel 31. The chain wheel shaft of the driven chain wheel 32 is fixed at the slide rails 34 arranged on the opposite sides of the support frame 51. Positioning sleeves are also installed at the two ends of the driven chain wheel 32 to prevent the driven chain wheel 32 from axially moving along the chain wheel shaft. The driving chain wheel 31 and the driven chain wheel 32 are drivingly connected through the chain 33. The chain 33 is connected with the material table 2 through a chain connecting rod 36. The rotary driving member 35 can be an electric motor matched with a speed reducer. The speed reducer is fixed on the support frame 51 and its output end is connected with the chain wheel shaft of the driving chain wheel 31. In order to prevent the chain wheel shaft of the driving chain wheel 31 from axially moving, a gland is arranged at the end of the chain wheel shaft penetrating out of the speed reducer. The material table 2 is in a U shape as a whole and comprises a sliding main plate 21 and sliding side plates 22 arranged on the opposite sides of the sliding main plate 21 perpendicular to the advancing direction. Compound roller assemblies 23 are installed on the sliding side plates 22. The compound roller assemblies 23 are slidingly matched with the slide rails 34. The compound roller assemblies 23 are prior art and will not be further described here. The driving chain wheel 31 drives the chain 33 to rotate under the action of the rotary driving member 35, so that the material table 2 connected with the chain 33 slides along the extension direction of the slide rails 34.

[0032] For the arc-shaped steel or other materials with large difference between length and width, the advancing direction of the material table should be perpendicular to the length direction of the material as much as possible in order to make the material automatically fall into the next process under the action of gravity, and in order to ensure the stability of the material during the advancing process, the clamping mechanism 4 generally clamps the material along the width direction of the material, so the clamping mechanism 4 needs to form an avoidance in the second state to prevent interference with the falling or sliding of the material. In the embodiment, the clamping mechanism 4 includes a first clamping assembly and a second clamping assembly, and the first clamping assembly and the second clamping assembly are respectively located on both sides of the width of the material when clamping the material, that is, the first clamping assembly and the second clamping assembly are arranged in the advancing direction of the material, and the first clamping assembly is close to the next process side and is provided with two groups, and the two groups of first clamping assemblies are respectively symmetrically arranged on the two sliding side plates 22, and include a first clamping piece 41 which is installed on the sliding side plate 22 and can be lifted, when the first clamping piece 41 is lowered below the height of the material table 2, the clamping effect on the material is lost, and the clamping mechanism 4 is converted from the first state to the second state, and at this time the first clamping piece 41 will not interfere with the sliding or falling of the material. In other embodiments, the first clamping assembly can also be realized by the clamping plate which is rotatably connected with the sliding side plate 22 to realize the clamping cooperation with the second clamping assembly or the avoidance of the material.

[0033] The second clamping assembly is also installed on the material table 2, and includes a second clamping piece 43 which can move close to and away from the material along the advancing direction of the material, and the second clamping piece 43 cooperates with the two first clamping pieces 41 to form a stable triangular structure to clamp the material, and the adjustable position of the second clamping assembly can make the clamping mechanism 4 applicable to materials of different sizes, and expand the application range of the feeding device. It can be understood that the first clamping assembly can also be provided as one group, and the second clamping assembly can be provided as two groups, and the two groups of second clamping assemblies and the one group of clamping assemblies can also form a stable triangular structure.

[0034] Reference Figure 2 and Figure 3As shown, based on the first clamping piece 41 being arranged to be liftable, the first clamping assembly further comprises an avoiding driving member 42, an output end of the avoiding driving member 42 is connected with the first clamping piece 41 to realize lifting of the first clamping piece 41. Exemplarily, the avoiding driving member 42 is selected as a pneumatic cylinder, the pneumatic cylinder is fixed on a transition connecting plate installed on the side of the sliding side plate 22 through a pneumatic cylinder base 24. In order to avoid axial movement of the pneumatic cylinder, the first clamping assembly further comprises a first guide member 45 and a second guide member 46 which are matched with each other, one of the first guide member 45 and the second guide member 46 is installed on the output end of the pneumatic cylinder, and the other is installed on the sliding side plate 22, and the first guide member 45 and the second guide member 46 are in sliding fit. Exemplarily, the first guide member 45 is a telescopic shaft, the second guide member 46 is a hollow sleeve, the output end of the pneumatic cylinder is connected with the telescopic shaft, and is specifically installed in the telescopic shaft through a loose joint, and the telescopic shaft is installed in the hollow sleeve, a key groove arranged in a vertical direction is formed in the telescopic shaft, and a guide block capable of sliding in the key groove is arranged in the hollow sleeve. In order to facilitate machining, the guide block and the main body of the hollow sleeve are detachably connected, a stepped hole for installing the guide block is formed through the side wall of the hollow sleeve, and the guide block is also arranged in a T shape, penetrates into the main body of the hollow sleeve from one side of the large-diameter section of the stepped hole and protrudes from the inner wall of the main body of the hollow sleeve to slide along the key groove. It can be understood that the length of the key groove is not through the end faces of the two ends of the telescopic shaft, so as to avoid the telescopic shaft from being separated from the hollow sleeve.

[0035] The first clamping piece 41 can be a bearing, and a plurality of bearings are sleeved on the telescopic shaft in the axial direction to reduce friction with the material during clamping, so as to ensure the smoothness of the surface of the arc-shaped steel as much as possible. Specifically, the telescopic shaft is arranged in a variable-diameter structure, the bearings can be clamped on the steps formed by the variable-diameter structure of the telescopic shaft, and the end of the telescopic shaft away from the pneumatic cylinder is also provided with a gland, and the gland cooperates with the steps to axially position the bearings.

[0036] Reference Figure 1 As shown, the second clamping assembly comprises a second clamping piece 43 and a clamping driving member 44, wherein the clamping driving member 44 is also selected as a pneumatic cylinder, the pneumatic cylinder is fixed on the transition connecting plate through a pneumatic cylinder connecting plate, and the output end of the pneumatic cylinder is fixed with the second clamping piece 43. The pneumatic cylinder is arranged to be telescopic, and the second clamping piece 43 is arranged to abut against or separate from the arc-shaped steel, so that the first clamping piece 41 and the second clamping piece 43 abut against or separate from the arc-shaped steel on both sides of the arc-shaped steel, so as to realize clamping or loosening of the arc-shaped steel. Exemplarily, the second clamping piece 43 is a pneumatic cylinder top head.

[0037] Each driving member in the clamping mechanism 4, the walking mechanism 3 and the lifting mechanism 5 needs to be connected with an electric wire cable, especially the driving member in the clamping mechanism 4 needs to move with the movement of the material table 2, and the position of the electric wire cable will also change. Therefore, the feeding device in the embodiment further comprises a drag chain 6 to facilitate the movement of the electric wire cable. Reference Figure 2As shown, the drag chain 6 is arranged below the support frame 51 through the connecting bracket 7, that is, the drag chain 6 forms an integral whole with the support frame 51.

[0038] When the clamping mechanism 4 clamps the arc-shaped steel, the first clamping piece 41 in the first clamping assembly rises and abuts against the arc-shaped steel, and the second clamping piece 43 in the second clamping assembly moves horizontally towards the arc-shaped steel and abuts against the arc-shaped steel, thereby realizing clamping of the arc-shaped steel; after clamping and fixing, the swing shaft 55 swings under the action of the lifting driving member, so that the walking mechanism 3 and the material table 2 located on the walking mechanism 3 are tilted and lifted, and at the same time, the material table 2 moves from the previous process to the next process; when the material table 2 slides to the device used in the next process, the first clamping piece 41 is lowered to a height below the material table 2, the arc-shaped steel rolls or slides under the action of gravity to the next process and falls into the next process, thereby realizing automatic material falling.
