Technical Field

[0001] The invention relates to the technical field of workpieces, and in particular to a conveying device for machining mechanical equipment. Background Art

[0002] The assembly line has high scalability and can be designed according to the needs of conveying volume, conveying speed, assembly stations, and auxiliary components. The assembly line is an effective combination of people and machines, which fully reflects the flexibility of the equipment. It organically combines the conveying system, accompanying fixtures, online special machines, and testing equipment to meet the conveying requirements of multiple varieties of products. The transmission mode of the conveyor line can be synchronous transmission or asynchronous transmission. According to the configuration selection, the assembly and conveying requirements can be achieved.

[0003] Conveyor lines are indispensable in the batch production of enterprises. Pipes are indispensable in the mechanical processing process. However, the weight of pipes is relatively large. Manual handling is not only more laborious, but also has low efficiency due to the limited handling speed. Therefore, step-by-step conveying equipment is used to transport the pipes, which facilitates the subsequent reprocessing of the pipes.

[0004] Since some step conveyors are provided with hook-shaped baffles at the tail end, some round tubes will be transported by the step conveyor after processing, and the step conveyor will transport the round tubes to the baffles for collection, and the round tubes at the baffles will accumulate more and more as the step conveyor is transported, and with the subsequent transportation of the round tubes, the round tubes at the baffles will collide with each other, which may easily cause the round tubes at the baffles to loosen and deviate, which may easily cause the accumulated round tubes to fall from the step conveyor, and after the round tubes at the baffles collide with each other, the positions of the round tubes will be staggered, which is inconvenient for the staff to extract them for subsequent processing.

[0027] The following will refer to the attached Figures 1 to 8The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0028] A conveying device for mechanical equipment processing, such as the attached Figures 1 to 8 As shown, including: The stepping conveyor 10 has a transport head end and a transport tail end, and the stepping conveyor 10 is used to transport round pipes, so as to facilitate the collection of round pipes. Two guide rails 11 are fixed to the transport tail end of the stepping conveyor 10. The guide rails 11 are arc-shaped, and the guide rails 11 have a top end and a bottom end. The end of the guide rail 11 close to the stepping conveyor 10 is the top end, and the end of the guide rail 11 away from the stepping conveyor 10 is the bottom end. The two guide rails 11 are symmetrical with the stepping conveyor 10 as the center, and are used to collect the round pipes. The guide rail 11 is used to guide the round pipes, thereby facilitating the collection of the round pipes. A connecting arm is fixed between the inner wall of the guide rail 11 and the stepping conveyor 10 for supporting the guide rail 11, thereby maintaining the stability of the guide rail 11. Guide plates 12 are fixed on 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 stepping conveyor 10 is the head end, and the end of the guide plate 12 away from the transport tail end of the stepping conveyor 10 is the tail end. There is an accommodating gap between the two guide plates 12, and the head end of the guide plate 12 has an arc-shaped surface.

[0029] A connecting box 13 is fixed to the transport tail end of the stepping conveyor 10 through a support arm, which is used to collect round pipes, thereby facilitating the collection of round pipes. A feed port 14 is opened on the side of the connecting box 13 facing the stepping conveyor 10, and the feed port 14 corresponds to the bottom end of the guide rail 11. The inner bottom wall of the feed port 14 is located below the bottom end of the guide rail 11, and the inner top wall of the feed port 14 is located above the bottom end of the guide rail 11. The feed port 14 is used to accommodate round pipes, thereby facilitating the round pipes to flow into the interior of the connecting box 13 for collection. An arc plate 15 is fixed to the inner wall of the connecting box 13, and the top end of the arc plate 15 is flush with the inner bottom wall of the feed port 14.

[0030] Two material receiving pieces 16 are installed inside the connection box 13, and the two material receiving pieces 16 are vertically arranged inside the connection box 13, so as to collect the circular pipes alternately, thereby improving the collection efficiency of the circular pipes.

[0031] The material receiving member 16 includes two connecting seats 160 slidably connected to the inside of the connecting box 13, the side of the connecting seat 160 close to the feed inlet 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 located at the upper end has an arc surface, and the arc surface of the connecting seat 160 faces the feed inlet 14, the connecting seat 160 has a plurality of stepped surfaces, and the stepped surface of the connecting seat 160 close to the feed inlet 14 is higher, and the connecting seat 160 is away from the feed inlet 14. The step surface of the feed port 14 is relatively low, and U-shaped plates 162 are fixed on the tops of the multiple step surfaces. A first fixed plate 161 is arranged between the three U-shaped plates 162. The three U-shaped plates 162 have a accommodating cavity inside, and the circular tubes can be stacked vertically inside the accommodating cavity, so that the circular tubes can be neatly arranged for subsequent processing. Openings are opened on the multiple first fixed plates 161, and the circular tubes can flow through the openings to the next accommodating cavity for collection, so that the circular tubes can be collected and arranged in sequence.

[0032] Since the opening has two states of opening and closing, when the opening is in the open state, the two adjacent accommodating chambers are connected, and when the opening is changed from the open state to the closed state, the two adjacent accommodating chambers are not connected. First, the transport head end of the stepping conveyor 10 is docked with the loading workpiece, and the round tube is transported to the stepping conveyor 10 through the loading workpiece. At this time, the stepping conveyor 10 can transport the round tube on its surface from the transport head end to its transport tail end. After the round tube at the transport tail end is transported to the guide rail 11, the round tube will enter the interior of the connection box 13 through the feed port 14, and the arc plate 1 The round tubes are introduced into the accommodating cavity of the U-shaped plate 162 at the end of the feed port 14. When a certain amount of round tubes are loaded into the accommodating cavity of the U-shaped plate 162 at the end of the feed port 14, the opening of the first fixing plate 161 adjacent to the U-shaped plate 162 is changed from a closed state to an open state, and the round tubes flow into the accommodating cavity of the next U-shaped plate 162 for collection. When the material receiving piece 16 at the lower end collects a certain amount of round tubes, the material receiving piece 16 at the lower end moves downward, and the material receiving piece 16 at the upper end also moves downward, and the above operation is repeated to collect the round tubes.

[0033] refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a conversion assembly 20 is disposed inside the connection box 13 for controlling the opening and closing state of the opening, thereby controlling the circular pipes to flow into different accommodating chambers for collection.

[0034] The conversion assembly 20 includes a baffle plate 21 rotatably connected to the inside of the baffle plate 21, which is used to guide the circular tube, so that the circular tube can flow to the adjacent accommodating chambers in sequence for stacking and collection. Accommodating grooves 22 are provided on both sides of the inner wall of the first fixed plate 161, and the two accommodating grooves 22 are symmetrical with the first fixed plate 161 as the center. The inner wall of the accommodating groove 22 is rotatably connected with a rotating shaft 23, and the side of the baffle plate 21 facing the rotating shaft 23 is fixed on the outer wall of the rotating shaft 23, and the rotating shaft 23 is used to support the baffle plate 21, so as to facilitate driving the baffle plate 21 to rotate and guide the circular tube. Two linkage gears 24 are installed on the outer surface of the rotating shaft 23, and the two linkage gears 24 are symmetrical with the baffle plate 21 as the center. The inner bottom wall of the accommodating groove 22 is slidably connected with a linkage rack 25, and the linkage rack 25 is meshed with the linkage gear 24. The linkage gear 24 cooperates with the linkage rack 25 to drive the rotating shaft 23 to rotate, so as to facilitate adjusting the angle of the baffle plate 21 to guide the circular tube.

[0035] A first return spring 26 is fixed between one side of the linkage rack 25 and the inner wall of the accommodating groove 22 for supporting the linkage rack 25, so as to facilitate the linkage rack 25 to be reset. A square opening 27 and an oblique opening 28 are provided on the plurality of U-shaped plates 162, and the square opening 27 and the oblique opening 28 are communicated, and the linkage rack 25 is located inside the square opening 27. A second fixed plate 29 is fixed between the two linkage gears 24, and three triangular linkage blocks 210 are fixed on one side of the second fixed plate 29, and the three triangular linkage blocks 210 are at equal distances from each other. The second fixed plate 29 cooperates with the triangular linkage blocks 210 to push the linkage rack 25, thereby driving the baffle 21 to rotate and adjust the angle through the rotating shaft 23 and the linkage gear 24. Two sets of shielding members 211 are fixed on the top of the U-shaped plate 162, and the shielding member 211 is composed of two shielding plates, and the shielding member 211 is located inside the gap between two adjacent triangular linkage blocks 210.

[0036] When the circular tube flows into the interior of the connecting box 13 through the feed port 14, the circular tube will be stacked inside the U-shaped plate 162 near the feed port 14. When the circular tube inside the U-shaped plate 162 is accumulated to the corresponding triangular linkage block 210, the triangular linkage block 210 is pushed by the gravity of the circular tube. The triangular linkage block 210 pushes the linkage rack 25 to slide inside the accommodating groove 22 and the square opening 27 through the second fixed plate 29, and the linkage rack 25 pushes the first return spring 26 for compression. At this time, the linkage gear 24 drives the baffle 21 to rotate around the axial direction of the rotating shaft 23 through the rotating shaft 23. The baffle 21 will turn to the direction of the feed port 14, and the baffle 21 will block the circular tubes stacked inside the U-shaped plate 162. The circular tubes that continue to enter the feed port 14 will flow through the baffle 21 to the inside of the next U-shaped plate 162, and continue to be stacked inside the accommodating cavity of the next U-shaped plate 162.

[0037] When the circular tubes in the next U-shaped plate 162 are also stacked to a certain number, the triangular linkage block 210 in the first fixed plate 161 is also pushed by the gravity of the circular tubes, and the same operation is repeated, and the subsequent circular tubes will flow into the U-shaped plate 162 at the tail end of the connection box 13, thereby releasing the limit of the lower end receiving piece 16 in the connection box 13, and the receiving piece 16 moves downward, while the receiving piece 16 at the upper end of the connection box 13 slides into the interior of the connection box 13, thereby continuing to collect the circular tubes, and the staff After taking out the circular tubes inside the lower end receiving piece 16, push the lower end receiving piece 16 upwards. At this time, the receiving piece 16 inside the connecting box 13 can be moved up and out of the connecting box 13, while the lower end receiving piece 16 continues to collect the circular tubes. At the same time, the staff takes out the circular tubes collected by the upper end receiving piece 16, thereby prompting the staff that the lower end receiving piece 16 has received enough circular tubes to accommodate and facilitating the staff to take them out. While the staff is taking them out, the circular tubes continue to be collected, thereby improving the efficiency of collecting the circular tubes.

[0038] refer to Figure 3 , Figure 4 and Figure 5 As shown, a limiting assembly 30 is installed on the connection box 13 for limiting the position of the material receiving piece 16 at the lower end, thereby maintaining the stability of the material receiving piece 16 .

[0039] The limiting assembly 30 includes a third fixed plate 31 arranged on the connecting box 13, and a plurality of second return springs 38 are fixed between the third fixed plate 31 and the connecting box 13 on one side thereof facing the connecting box 13. The plurality of second return springs 38 are equidistant from each other, and the second return springs 38 are used to support the third fixed plate 31, so as to facilitate the reset of the third fixed plate 31. Two first sliding grooves 32 and a third sliding groove 37 are provided on the connecting box 13, and the two first sliding grooves 32 are symmetrical with the third fixed plate 31 as the center. Two second sliding grooves 33 are provided on the U-shaped plate 162 at the rear end of the connecting box 13, and the second sliding grooves 33 correspond to the first sliding grooves 32.

[0040] The first sliding groove 32 is internally slidably connected with a first limiting column 34, and one end of the first limiting column 34 is fixed on a side wall of the third fixed plate 31, and the first limiting column 34 is inserted into the second sliding groove 33 to limit the connecting piece 16, thereby maintaining the stability of the connecting piece 16, and the third sliding groove 37 is internally slidably connected with a second limiting column 36, the second limiting column 36 and one end of the first limiting column 34 facing the connecting box 13 both have an arc-shaped surface, and one end of the second limiting column 36 is fixed on a side wall of the third fixed plate 31.

[0041] When the circular tube enters the U-shaped plate 162 at the rear end of the connecting box 13, the second limiting column 36 is pushed by the circular tube, and the third fixing plate 31 slides to the side away from the connecting box 13. At the same time, the second limiting column 36 slides out of the third sliding groove 37. At this time, the material receiving piece 16 at the lower end is disengaged from the limit of the second limiting column 36, and the material receiving piece 16 at the upper end slides into the interior of the connecting box 13 to collect the circular tube, so that the two material receiving pieces 16 collect the circular tube alternately. After the circular tubes collected by the lower material receiving piece 16 are taken out, the lower material receiving piece 16 is pushed upward. At this time, the upper material receiving piece 16 slides out of the connecting box 13, and then the circular tubes collected inside the upper material receiving piece 16 are taken out.

[0042] refer to Figure 8 As shown, a movable groove is opened on one side of the U-shaped plate 162, and a pulling assembly 40 is installed inside the movable groove to facilitate the staff to pull out the U-shaped plate 162 and thus take out the round pipes collected inside the U-shaped plate 162.

[0043] The pulling assembly 40 includes a handle 41, and the handle 41 is slidably connected to the inside of the movable groove, and the edge of the handle 41 has an arc surface. A third return spring 42 is fixed between the handle 41 and the movable groove, which is used to support the handle 41, so as to facilitate the reset of the handle 41. When the material receiving piece 16 is located inside the connecting box 13, the third return spring 42 is in a compressed state. When the material receiving piece 16 slides out of the connecting box 13, the third return spring 42 resets and drives the handle 41 to slide out of the movable groove, so that it is convenient for the staff to pull out the U-shaped plate 162 and take out the round tube inside the U-shaped plate 162.
