Description

Technical Field

[0001] The present invention relates to the technical field of workpieces, and specifically relates to a conveying device for mechanical equipment processing. Background Art

[0002] The assembly line has high scalability and can be designed according to requirements for conveying volume, conveying speed, assembly stations, auxiliary components. The assembly line is an effective combination of humans and machines, most fully reflecting the flexibility of the equipment. It organically combines a conveying system, a traveling fixture, an on-line special machine, and a detection device to meet the conveying requirements of multi-variety products. The transmission method of the conveying line can be synchronous transmission or asynchronous transmission. According to the selection of configuration, the requirements of assembly and conveying can be achieved.

[0003] The conveying line is indispensable in the batch production of enterprises. In the process of mechanical processing, pipes are essential. However, the quality of pipes is relatively large, and manual handling is not only laborious, but also has low efficiency due to limited handling speed. Therefore, a step-by-step conveying device is used to convey the pipes, facilitating subsequent reprocessing of the pipes.

[0004] Since a hook-shaped stopper is provided at the tail end of some step-by-step conveyors, and some circular pipes after processing are conveyed by the step-by-step conveyor, and the step-by-step conveyor conveys the circular pipes to the stopper for collection. As the step-by-step conveyor conveys the circular pipes, more and more circular pipes will accumulate at the stopper. With the subsequent conveyance of circular pipes, the circular pipes at the stopper will collide with each other, easily causing the circular pipes at the stopper to become loose and deviate, and thus easily causing the stacked circular pipes to fall off the step-by-step conveyor. Moreover, after the circular pipes at the stopper collide with each other, the positions of the circular pipes will be staggered, making it inconvenient for workers to extract them for subsequent processing.

[0005] Therefore, the present invention provides a conveying device for mechanical equipment processing to solve the above problems. Summary of the Invention

[0006] In view of the above situation, to overcome the deficiencies of the prior art, the present invention provides a conveying device for mechanical equipment processing to solve the problems that when the stacked circular pipes collide with each other, the circular pipes will be misaligned and fall off.

[0007] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0008] A conveying device for mechanical equipment processing includes a step-by-step conveyor. A guide rail is installed on one side of the step-by-step conveyor. A connection box is installed on one side of the step-by-step conveyor. The connection box is provided with a feed port on the side facing the step-by-step conveyor. An arc-shaped plate is fixed to the inner wall of the connection box. Two receiving members are provided inside the connection box.

[0009] The material receiving part includes a connecting seat which has three stepped surfaces. On each of the three stepped surfaces of the connecting seat, a first fixed plate and a U-shaped plate are fixed. Each of the multiple U-shaped plates has a receiving cavity. An opening is formed on the first fixed plate, and the opening has two states of opening and closing. When the circular pipes conveyed on the step conveyor fall into the connecting box through the feed inlet, the U-shaped plate near the feed inlet will first collect the circular pipes. After a certain number of circular pipes are collected by the U-shaped plate, the opening on the adjacent first fixed plate changes from the closed state to the open state, and the circular pipes will slide into the next U-shaped plate for continuous collection. When the circular pipes slide into the U-shaped plate at the tail end of the connecting seat, the lower material receiving part slides out of the connecting box, and the upper material receiving part slides into the connecting box for continuous collection, so as to neatly collect the circular pipes.

[0010] The conversion component is installed inside the connecting box and is used to control the opening and closing state of the opening, so that the circular pipes can be collected in the U-shaped plates of the connecting seat in sequence.

[0011] Preferably, the conversion component includes a baffle plate rotatably connected inside the opening. On both sides of the inner wall of the first fixed plate, receiving grooves are formed, and the two receiving grooves are symmetric about the first fixed plate. A rotating shaft is rotatably connected to the inner wall of the receiving groove, and one side of the baffle plate facing the rotating shaft is fixed on the outer wall of the rotating shaft. The rotating shaft is used to support the baffle plate, so as to drive the baffle plate to rotate to guide the circular pipes.

[0012] Preferably, two linkage gears are installed on the outer surface of the rotating shaft, and the two linkage gears are symmetric about the baffle plate. A linkage rack is slidably connected to the inner bottom wall of the receiving groove, and the linkage rack is meshed with the linkage gear. The linkage gear and the linkage rack can drive the rotating shaft to rotate, so as to adjust the angle of the baffle plate to guide the circular pipes. A first return spring is fixed between one side of the linkage rack and the inner wall of the receiving groove to support the linkage rack and facilitate the reset of the linkage rack.

[0013] Preferably, square openings and inclined openings are formed on each of the multiple U-shaped plates, and the square openings and the inclined openings are communicated. The linkage rack is located inside the square opening. A second fixed plate is fixed between the two linkage gears. Three triangular linkage blocks are fixed on one side of the second fixed plate, and the distances between the three triangular linkage blocks are equal. The second fixed plate and the triangular linkage blocks are used to push the linkage rack, so as to drive the baffle plate to rotate and adjust the angle through the rotating shaft and the linkage gear to guide the circular pipes.

[0014] Preferably, two groups of shielding parts are fixed on the top of the U-shaped plate, and each shielding part is composed of two shielding plates, and the shielding parts are located inside the gaps between adjacent two triangular linkage blocks.

[0015] Preferably, a limiting component is installed on the connection box to limit the material receiving component at the lower end, thereby maintaining the stability of the material receiving component.

[0016] Preferably, the limiting component includes a third fixing plate arranged on the connection box. A plurality of second return springs are fixed between the side of the third fixing plate facing the connection box and the connection box. The distances between the plurality of second return springs are equal. Two first sliding grooves and a third sliding groove are formed on the connection box. The two first sliding grooves are symmetric with respect to the third fixing plate. Two second sliding grooves are formed on the U-shaped plate at the end of the connection box, and the second sliding grooves correspond to the first sliding grooves. A first limiting column is slidably connected inside the first sliding groove, and one end of the first limiting column is fixed on a side wall of the third fixing plate, and the first limiting column is inserted into the inside of the second sliding groove. A second limiting column is slidably connected inside the third sliding groove. The ends of the second limiting column and the first limiting column facing the connection box both have arc-shaped surfaces, and one end of the second limiting column is fixed on a side wall of the third fixing plate.

[0017] Preferably, a moving groove is formed on one side of the U-shaped plate, and a pulling component is installed inside the moving groove, which is convenient for the staff to pull out the U-shaped plate, so as to take out the circular pipes collected inside the U-shaped plate.

[0018] Preferably, the pulling component includes a handle, and the handle is slidably connected inside the moving groove, and the edge of the handle has an arc-shaped surface. A third return spring is fixed between the handle and the moving groove to support the handle, so as to facilitate driving the handle to reset. When the material receiving component is inside the connection box, the third return spring is in a compressed state at this time. When the material receiving component slides out of the inside of the connection box, the third return spring resets and drives the handle to slide out of the moving groove, so as to facilitate the staff to pull out the U-shaped plate and take out the circular pipes inside the U-shaped plate.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. Through the connection box arranged on the step conveyor, the feeding port formed on the connection box, the arc-shaped plate arranged on the inner wall of the connection box and the material receiving component, the material receiving component includes a connection seat, a first fixing plate and a U-shaped plate, the opening formed on the first fixing plate, and the opening has two states of opening and closing. When the circular pipes conveyed on the step conveyor fall into the connection box through the feeding port, the U-shaped plate close to the feeding port will collect the circular pipes first. After the U-shaped plate collects a certain number, the opening on the adjacent first fixing plate changes from the closed state to the open state, and the circular pipes will slide into the inside of the next U-shaped plate for continuous collection. When the circular pipes slide into the U-shaped plate at the end of the connection seat, the lower material receiving component slides out of the connection box, and the upper material receiving component slides into the connection box for continuous collection, so as to facilitate reminding the staff that the lower material receiving component has received enough circular pipes that can be accommodated and is convenient for the staff to take out.

[0021] 2. The conversion component arranged inside the connection box is used to control the opening and closing state of the opening, so that the circular pipes can be stacked inside the U-shaped plate of the connection seat in sequence, enabling the circular pipes to be neatly stacked inside the U-shaped plate, which is convenient for the staff to perform subsequent processing on the circular pipes.

[0035] The following will refer to the reference appendix Figures 1 to 8 to describe each embodiment of the present invention in detail. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0036] A conveying device for machining mechanical equipment, as shown in the appendix Figures 1 to 8 shown, includes:

[0037] A step conveyor 10, and the step conveyor 10 has a transport head end and a transport tail end, and the step conveyor 10 is used to transport circular pipes, so as to facilitate the collection of circular pipes. Two guide rails 11 are fixed at the transport tail end of the step conveyor 10. The guide rails 11 are arc-shaped. The guide rails 11 have a top end and a bottom end, and the end of the guide rail 11 close to the step conveyor 10 is the top end, and the end of the guide rail 11 far from the step conveyor 10 is the bottom end. And the two guide rails 11 are symmetric with the step conveyor 10 as the center, and are used to guide the circular pipes, so as to facilitate the collection of the circular pipes. A connecting arm is fixed between the inner wall of the guide rail 11 and the step conveyor 10, and is used to support the guide rail 11, so as to maintain the stability of the guide rail 11. Guide plates 12 are fixed on both of the two guide rails 11. The guide plates 12 are arc-shaped, and the end of the guide plate 12 close to the transport tail end of the step conveyor 10 is the head end, and the end of the guide plate 12 far from the transport tail end of the step conveyor 10 is the tail end. There is an accommodation gap between the two guide plates 12, and the head end of the guide plate 12 has an arc-shaped surface.

[0038] A connecting box 13 is fixed at the transport tail end of the step conveyor 10 through a support arm, and is used to collect circular pipes, so as to facilitate the collection of circular pipes. An inlet 14 is opened on the side of the connecting box 13 facing the step conveyor 10, and the inlet 14 corresponds to the bottom end of the guide rail 11. The inner bottom wall of the inlet 14 is located below the bottom end of the guide rail 11, and the inner top wall of the inlet 14 is located above the bottom end of the guide rail 11. The inlet 14 is used to accommodate circular pipes, so as to facilitate the circular pipes to flow into the inside of the connecting box 13 for collection. An arc-shaped plate 15 is fixed on the inner wall of the connecting box 13, and the top end of the arc-shaped plate 15 is flush with the inner bottom wall of the inlet 14.

[0039] Two receiving members 16 are installed inside the connecting box 13, and the two receiving members 16 are vertically arranged inside the connecting box 13, and can alternately collect circular pipes, so as to improve the collection efficiency of circular pipes.

[0040] The material receiving member 16 includes two connecting seats 160 slidably connected inside the connecting box 13. The side of the connecting seat 160 close to the feeding port 14 is the head end, and the other side of the connecting seat 160 is the tail end. The two connecting seats 160 are vertically arranged inside the connecting box 13, and the bottom of the connecting seat 160 at the upper end has an arc surface, and the arc surface of the connecting seat 160 faces the feeding port 14. The connecting seat 160 has a plurality of stepped surfaces, and the stepped surface of the connecting seat 160 close to the feeding port 14 is higher, and the stepped surface of the connecting seat 160 far from the feeding port 14 is lower. U-shaped plates 162 are fixed on the tops of the plurality of stepped surfaces. First fixing plates 161 are arranged between every two of the three U-shaped plates 162. Each of the three U-shaped plates 162 has an accommodation cavity inside, and circular pipes can be vertically stacked inside the accommodation cavity, so as to facilitate the neat arrangement of the circular pipes for subsequent processing. Openings are formed on the plurality of first fixing plates 161, and the circular pipes can flow through the openings to the next accommodation cavity for collection, so as to facilitate the collection and arrangement of the circular pipes in sequence.

[0041] Since the opening has two states of opening and closing, when the opening is in the open state, two adjacent accommodation cavities are communicated, and when the opening is changed from the open state to the closed state, two adjacent accommodation cavities are not communicated. First, the head end of the step conveyor 10 is butted with the feeding workpiece, and the circular pipes are transported to the step conveyor 10 through the feeding workpiece. At this time, the step conveyor 10 can transport the circular pipes on its surface from the transport head end to its transport tail end. After the circular pipes at the transport tail end are transported to the guide rail 11, the circular pipes will enter the inside of the connecting box 13 through the feeding port 14, and the arc-shaped plate 15 guides the circular pipes into the accommodation cavity of the U-shaped plate 162 at the feeding port 14 end. When a certain amount of circular pipes are loaded into the accommodation cavity of the U-shaped plate 162 at the feeding port 14 end, at this time, the opening of the first fixing plate 161 adjacent to the U-shaped plate 162 is changed from the closed state to the open state, and the circular pipes will flow into the accommodation cavity of the next U-shaped plate 162 for collection. After a certain amount of circular pipes are collected by the lower material receiving member 16, at this time, the lower material receiving member 16 will move down, and the upper material receiving member 16 will also move down, and the above operations are repeated to collect the circular pipes.

[0042] Reference Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 And Figure 8 As shown in, a conversion assembly 20 is arranged inside the connecting box 13, which is used to control the opening and closing state of the opening, so as to control the flow direction of the circular pipes into different accommodation cavities for collection.

[0043] The conversion component 20 includes a baffle 21 rotatably connected inside the baffle 21, which is used to guide the circular pipe, so as to facilitate the circular pipe to flow into the adjacent accommodation cavity in sequence for stacking and collection. Accommodation grooves 22 are formed on both sides of the inner wall of the first fixing plate 161, and the two accommodation grooves 22 are symmetric about the first fixing plate 161. A rotating shaft 23 is rotatably connected to the inner wall of the accommodation groove 22, and one side of the baffle 21 facing the rotating shaft 23 is fixed to the outer wall of the rotating shaft 23. The rotating shaft 23 is used to support the baffle 21, so as to facilitate driving the baffle 21 to rotate to guide the circular pipe. Two linkage gears 24 are installed on the outer surface of the rotating shaft 23, and the two linkage gears 24 are symmetric about the baffle 21. A linkage rack 25 is slidably connected to the inner bottom wall of the accommodation groove 22, and the linkage rack 25 is meshed with the linkage gear 24. The linkage gear 24 and the linkage rack 25 cooperate to drive the rotating shaft 23 to rotate, so as to facilitate adjusting the angle of the baffle 21 to guide the circular pipe.

[0044] A first return spring 26 is fixed between one side of the linkage rack 25 and the inner wall of the accommodation groove 22, which is used to support the linkage rack 25, so as to facilitate driving the linkage rack 25 to reset. Square openings 27 and inclined openings 28 are formed on multiple U-shaped plates 162, and the square openings 27 and the inclined openings 28 are communicated, and the linkage rack 25 is located inside the square opening 27. A second fixing plate 29 is fixed between the two linkage gears 24. Three triangular linkage blocks 210 are fixed to one side of the second fixing plate 29, and the distances between the three triangular linkage blocks 210 are equal. The second fixing plate 29 and the triangular linkage blocks 210 cooperate to push the linkage rack 25, so as to drive the baffle 21 to rotate and adjust the angle through the rotating shaft 23 and the linkage gear 24. Two groups of shielding parts 211 are fixed to the top of the U-shaped plate 162, and the shielding parts 211 are composed of two shielding plates, and the shielding parts 211 are located inside the gap between two adjacent triangular linkage blocks 210.

[0045] After the circular pipe flows into the inside of the connection box 13 through the feed inlet 14, at this time, the circular pipe will be stacked inside the U-shaped plate 162 close to the feed inlet 14. When the circular pipe inside the U-shaped plate 162 accumulates to the corresponding triangular linkage block 210, the triangular linkage block 210 is pushed by the gravity of the circular pipe. The triangular linkage block 210 pushes the linkage rack 25 to slide inside the accommodation groove 22 and the square opening 27 through the second fixing plate 29, and the linkage rack 25 compresses the first return spring 26. At this time, the linkage gear 24 drives the baffle 21 to rotate around the axis of the rotating shaft 23 through the rotating shaft 23, and the baffle 21 will turn towards the direction of the feed inlet 14, and the baffle 21 will block above the circular pipe stacked inside the U-shaped plate 162. The circular pipe continuously entering from the feed inlet 14 will flow through the baffle 21 into the inside of the next U-shaped plate 162, so as to continue to be stacked inside the accommodation cavity of the next U-shaped plate 162.

[0046] When the circular pipes inside the next U-shaped plate 162 are also stacked to a certain number, the triangular linkage block 210 inside the first fixing plate 161 is also pushed by the gravity of the circular pipes, and the same operation is repeated. And the subsequent circular pipes will flow into the U-shaped plate 162 at the tail end of the connection box 13, so as to release the limit of the lower receiving part 16 inside the connection box 13, and the receiving part 16 moves downward. And the receiving part 16 at the upper end of the connection box 13 slides into the connection box 13, so as to continue collecting the circular pipes. After the staff takes out the circular pipes inside the lower receiving part 16, the lower receiving part 16 is pushed up. At this time, the receiving part 16 inside the connection box 13 can move out of the connection box 13 upward, and the lower receiving part 16 continues to collect the circular pipes. At the same time, the staff takes out the circular pipes collected by the upper receiving part 16, so as to facilitate reminding the staff that the lower receiving part 16 has received enough circular pipes that can be accommodated, and it is convenient for the staff to take them out. And while the staff takes them out, the circular pipes are continuously collected, so as to improve the collection efficiency of the circular pipes.

[0047] Reference Figure 3 、 Figure 4 And Figure 5 As shown, a limiting component 30 is installed on the connection box 13, which is used to limit the lower receiving part 16, so as to maintain the stability of the receiving part 16.

[0048] The limiting component 30 includes a third fixing plate 31 arranged on the connection box 13. A plurality of second return springs 38 are fixed between the side of the third fixing plate 31 facing the connection box 13 and the connection box 13. The distances between the plurality of second return springs 38 are equal to each other, and the second return springs 38 are used to support the third fixing plate 31, so as to facilitate driving the third fixing plate 31 to reset. Two first sliding grooves 32 and a third sliding groove 37 are formed on the connection box 13, and the two first sliding grooves 32 are symmetrically arranged with the third fixing plate 31 as the center. Two second sliding grooves 33 are formed on the U-shaped plate 162 at the tail end of the connection box 13, and the second sliding grooves 33 correspond to the first sliding grooves 32.

[0049] A first limiting column 34 is slidably connected inside the first sliding groove 32, and one end of the first limiting column 34 is fixed on one side wall of the third fixing plate 31, and the first limiting column 34 is inserted into the second sliding groove 33, which is used to limit the receiving part 16, so as to maintain the stability of the receiving part 16. A second limiting column 36 is slidably connected inside the third sliding groove 37. The ends of the second limiting column 36 and the first limiting column 34 facing the connection box 13 both have arc-shaped surfaces, and one end of the second limiting column 36 is fixed on one side wall of the third fixing plate 31.

[0050] When a circular pipe enters the inside of the U-shaped plate 162 at the end of the connection box 13, the second limit post 36 is pushed by the circular pipe at this time, and the third fixing plate 31 slides to the side away from the connection box 13. At the same time, the second limit post 36 slides out of the third sliding groove 37. At this time, the lower receiving part 16 is released from the limit of the second limit post 36, and the upper receiving part 16 slides into the inside of the connection box 13 to collect the circular pipe. Thus, the two receiving parts 16 alternately collect the circular pipes. After all the circular pipes collected by the lower receiving part 16 are taken out, the lower receiving part 16 is pushed upward. At this time, the upper receiving part 16 slides out of the connection box 13, and then the circular pipes collected inside the upper receiving part 16 are taken out.

[0051] Reference Figure 8 As shown, an activity groove is provided on one side of the U-shaped plate 162, and a pulling component 40 is installed inside the activity groove, which is convenient for the staff to pull out the U-shaped plate 162, so as to take out the circular pipes collected inside the U-shaped plate 162.

[0052] The pulling component 40 includes a handle 41, and the handle 41 is slidably connected inside the activity groove. The edge of the handle 41 has an arc surface. A third return spring 42 is fixed between the handle 41 and the activity groove to support the handle 41, so as to facilitate driving the handle 41 to reset. When the receiving part 16 is inside the connection box 13, the third return spring 42 is in a compressed state at this time. When the receiving part 16 slides out of the inside of the connection box 13, the third return spring 42 resets and drives the handle 41 to slide out of the activity groove, so as to facilitate the staff to pull out the U-shaped plate 162 and take out the circular pipes inside the U-shaped plate 162.
