[0018] The present application will now be described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present application in a schematic manner, and therefore only show the components related to the present application.

[0019] like Figure 1-5 As shown, a device for automatic loading and unloading includes a loading mechanism 1 and a unloading mechanism 2, the loading mechanism 1 is located at the feeding end of the processing area 3, and the unloading mechanism 2 is located at the discharging end of the processing area 3; the loading mechanism 1 includes a support plate 19, an inclined guide conveyor belt 10, an end of the guide conveyor belt 10 away from the processing area 3 is horizontally arranged, and an end of the guide conveyor belt 10 close to the processing area 3 is vertically arranged; the support plate 19 is arranged below a section of the guide conveyor belt 10 close to the processing area 3; the unloading mechanism 2 includes a discharging conveyor belt 20, and the feeding end of the discharging conveyor belt 20 is connected to the discharging end of the processing area 3.

[0020] The inclined guide conveyor belt 10 is used for loading materials. The oil pipe coupling is gradually transformed from horizontal to vertical under the action of the guide conveyor belt 10, and is supported by the support plate 19 to obtain a posture that can be transported.

[0021] The end of the guide conveyor belt 10 away from the processing area 3 is horizontally arranged, that is, the surface of the conveyor belt that plays a conveying role is horizontally arranged, and the end of the guide conveyor belt 10 close to the processing area 3 is vertically arranged, that is, the surface of the conveyor belt that plays a conveying role is vertical.

[0022] When the oil pipe coupling is located at the end of the guide conveyor belt 10 away from the processing area 3, the oil pipe coupling is supported by the guide conveyor belt 10. When the oil pipe coupling is located at the end of the guide conveyor belt 10 close to the processing area 3, the oil pipe coupling is gradually supported by the support plate 19 and finally falls completely on the support plate 19. A baffle 12 is also provided on the frame 13. The baffle 12 is specifically provided on one side of the vertical part of the guide conveyor belt 10 and the oil pipe coupling to prevent the oil pipe coupling from falling.

[0023] Under the action of the loading mechanism 1, the horizontal oil pipe coupling is transformed into a vertical setting to facilitate transportation and processing. After the oil pipe coupling is processed, it can be transported to the next workstation through the unloading mechanism 2. Compared with the device that uses a mechanical arm for loading and unloading, the initial cost and subsequent maintenance cost are greatly reduced.

[0024] In some further embodiments, the loading mechanism 1 also includes a transverse conveying roller 11 and a longitudinal conveying roller, and both the transverse conveying roller 11 and the longitudinal conveying roller are rotatably set on the frame 13; the longitudinal conveying roller is set close to the processing area 3, and the transverse conveying roller 11 is set away from the processing area 3, and the guide conveyor belt 10 is mounted on the transverse conveying roller 11 and the longitudinal conveying roller.

[0025] The guide conveyor belt 10 is respectively mounted on the transverse conveyor roller 11 and the longitudinal conveyor roller, wherein the transverse conveyor roller 11 is a power roller. When the transverse conveyor roller 11 rotates, the guide conveyor belt 10 and the longitudinal conveyor roller will be driven to rotate synchronously to realize the transportation of the oil pipe coupling.

[0026] In this embodiment, the transverse conveying roller 11 and the longitudinal conveying roller are vertically arranged in space.

[0027] The vertically arranged transverse conveying rollers 11 and longitudinal conveying rollers cause the guide conveying belt 10 to be in a twisted state, so that the oil pipe clamps conveyed thereon gradually tilt during the conveying process, thereby changing from a horizontal state to a vertical state.

[0028] At the same time, the transverse conveying roller 11 and the longitudinal conveying roller arranged perpendicular to each other can also play a good limiting role on the guide conveyor belt 10, that is, when the guide conveyor belt 10 arranged on the transverse conveying roller 11 deviates axially along the transverse conveying roller 11, the longitudinal conveying roller can well restrain the guide conveyor belt 10, thereby preventing the guide conveyor belt 10 from moving in the horizontal direction; and when the guide conveyor belt 10 arranged on the transverse conveying roller 11 deviates axially along the longitudinal conveying roller, the transverse conveying roller 11 can well restrain the conductor conveyor belt, thereby preventing the guide conveyor belt 10 from moving in the vertical direction.

[0029] In some further embodiments, a bending portion 190 is provided at one end of the support plate 19 close to the processing area 3 , and the bending portion 190 and the support plate 19 together form a temporary storage area for placing the oil pipe coupling.

[0030] The temporary storage area is formed by enclosing the support plate 19 and the bent portion 190 to prevent the oil pipe coupling from further sliding and falling off; the bent portion 190 can be provided integrally with the support portion.

[0031] In some further embodiments, the feeding mechanism 1 also includes an elastic limit frame, which includes a limit portion 14, a spring 16, and a mounting column 15; the mounting column 15 is vertically arranged on the frame 13, and a mounting handle is arranged on the limit portion 14, and a mounting hole is arranged on the mounting handle. The mounting handle is sleeved on the mounting column 15 through the mounting hole, and a limit handle 17 is arranged on the top of the mounting column 15. The spring 16 is sleeved on the mounting column 15, and the top of the spring 16 abuts against the bottom wall of the mounting handle, and the bottom of the spring 16 abuts against the frame 13; the spring 16 is in a compressed state; the limit portion 14 is located above the temporary storage area to assist in pressing the oil pipe coupling.

[0032] After the oil pipe couplings are transported to the temporary storage area, subsequent oil pipe couplings will continue to be transported. In order to prevent the oil pipe couplings in the temporary storage area from tilting or falling under the impact of subsequent oil pipe couplings, an elastic limit frame is set above the temporary storage area to temporarily fix the oil pipe couplings in the temporary storage area.

[0033] Specifically, a limiting plate 140 is provided on the limiting portion 14, and the limiting plate 140 has the same inclination angle as the support plate 19. When the oil pipe coupling enters the temporary storage area, the limiting portion 14 slides upward along the mounting column 15 under the action of the oil pipe coupling, and the spring 16 is further compressed. The elastic force of the spring 16 acts on the oil pipe coupling, thereby limiting the oil pipe coupling.

[0034] In some further embodiments, guard plates 21 are respectively provided on both sides of the discharge conveyor belt 20, and arc-shaped straightening plates 22 are provided on the guard plates 21. One end of the arc-shaped straightening plate 22 which is opposite to the conveying direction of the discharge conveyor belt 20 is arranged on the inner side of the guard plate 21, and one end of the arc-shaped straightening plate 22 which is in the same direction of the conveying direction of the discharge conveyor belt 20 is located close to the middle of the two guard plates 21.

[0035] Guard plates 21 are provided on both sides of the discharge conveyor belt 20 to prevent the oil pipe couplings from falling. In order to further ensure that the oil pipe couplings can be neatly conveyed out from the same position on the discharge conveyor belt 20, arc-shaped sorting plates 22 are provided on the two guard plates 21. The oil pipe couplings scattered on the discharge conveyor belt 20 are arranged in a row under the action of the two arc-shaped sorting plates 22 and transported by the discharge conveyor belt 20, so as to facilitate the subsequent processing of the oil pipe couplings at the next workstation.

[0036] In some further embodiments, an adjusting rod 23 is provided on the guard plate 21, one end of the adjusting rod 23 passes through the guard plate 21 and is rotatably connected to the arc-shaped straightening plate 22, and a bolt 24 is screwed on a section of the adjusting rod 23 located on the side of the guard plate 21 facing away from the arc-shaped straightening plate 22.

[0037] The distance between the two arc-shaped straightening plates 22 can be adjusted. When the distance between the two arc-shaped straightening plates 22 needs to be increased, the bolts 24 on the two adjusting rods 23 can be rotated synchronously to make the corresponding arc-shaped straightening plates 22 on the guard plate 21 move away from each other; when the position of a row of oil pipe couplings on the discharge conveyor belt 20 needs to be adjusted, the corresponding bolts 24 on one guard plate 21 can be tightened, and the corresponding bolts 24 on the other guard plate 21 can be loosened.

[0038] In some further embodiments, a rotating frame 30 is further included. The rotating frame 30 is slidably arranged in the processing area 3 along the direction from the loading mechanism 1 to the unloading mechanism 2. The rotating frame 30 includes a plurality of rotating rods 31 arranged at circumferential intervals. The rotating rods 31 are located in the same horizontal plane. A rotating rod 32 for sleeved oil pipe couplings is rotatably provided at the free end of the rotating rod 31. The rotating rod 32 is located in the same horizontal plane as the rotating rod 31 and is perpendicular to the rotating rod 31.

[0039] A rotating rod 31 is provided on the rotating frame 30, and a rotating rod 32 is provided at the free end of the rotating rod 31. When the rotating rod 31 is caught, each time a rotating rod 31 rotates through the temporary storage area, the rotating rod 32 corresponding to the rotating rod 31 can always take away the oil pipe coupling set on the temporary storage area, that is, the oil pipe coupling is just hung on the rotating rod 32.

[0040] The number of the rotating rods 31 can be multiple, and specifically in this embodiment, the number of the rotating rods 31 is four.

[0041] In some further embodiments, the rotating rod 32 is tilted, that is, the free end of the rotating rod 32 is higher than the rotating end, so as to prevent the oil pipe coupling penetrating the rotating rod 32 from falling off during the rotation process.

[0042] In some further embodiments, a first motor is provided on the rotating frame 30, the rotating rod 31 is located on the rotating shaft of the first motor, a fixed sleeve 37 is provided on the rotating frame 30, the fixed sleeve 37 is arranged concentrically with the rotating shaft, and the outer peripheral wall of the fixed sleeve 37 is provided with a plurality of first annular grooves 370 arranged at intervals along the vertical direction, and the first annular grooves 370 are located in a horizontal plane, and a second annular groove 320 is provided on the rotating rod 32, and the second annular groove 320 is located in a vertical plane, and the second annular groove 320 is connected to the corresponding first annular groove 370 through a transmission belt.

[0043] The first motor is used to drive the rotation of the rotating rod 31. The fixed sleeve 37 provided on the rotating frame 30 is sleeved on the outside of the rotating shaft and is not connected to the rotating shaft, but the fixed sleeve 37 is concentrically arranged with the rotating shaft. A plurality of first annular grooves 370 are arranged at intervals on the outer peripheral wall of the fixed sleeve 37, and the number of the first annular grooves 370 is the same as the number of the rotating rod 31; correspondingly, a second annular groove 320 is provided on one end of each rotating rod 32 close to the rotating rod 31, and a transmission belt is sleeved on the first annular groove 370, and the transmission belt is synchronously sleeved in the second annular groove 320. When the rotating rod 31 rotates, since the fixed sleeve 37 does not rotate, under the action of the transmission belt, the rotating rod 31 rotates and the transmission belt will drive the rotating rod 32 to rotate, thereby rotating the oil pipe coupling hung on the rotating rod 32, so that the surface of the oil pipe coupling can be more evenly painted.

[0044] In some further embodiments, a slide rail 34 and a rack 33 are further included; the slide rail 34 and the rack 33 are both arranged in the processing area 3, and the bottom of the rotating frame 30 is slidably arranged with the slide rail 34; a second motor is provided on the rotating frame 30, and a gear 38 is provided on the rotating shaft of the second motor, and the gears 38 are meshed with each other.

[0045] The entire rotating frame 30 can move to slide from the feed end of the processing area 3 to the discharge end of the processing area 3. During this process, the rotating rod 31 rotates, and the rotating rod 32 also rotates under the action of the transmission belt, so that the oil pipe coupling can be sprayed in all directions; in addition, due to the movement of the rotating frame 30, sprayers for different spray materials, such as primer, color paint, etc., can be set in the processing area 3.

[0046] The second motor controls the gear 38 to rotate, and under the action of the gear 38 and the rack 33, the entire rotating frame 30 is driven to slide along the slide.

[0047] In some further embodiments, a lever 35 is further included. The lever 35 is located at the feed end of the discharge conveyor belt 20. A paddle 36 is provided on the lever 35 for pulling out the oil pipe coupling hung on the rotating shaft.

[0048] When the rotating frame 30 is transported to the discharge end of the processing area 3, the first motor can be reversed. During the reversal process, the paddle 36 on the paddle rod 35 just pushes the oil pipe coupling hung on the rotating shaft off the rotating shaft and drops it onto the discharge conveyor belt 20, thereby completing the unloading.

[0049] The bottom of the oil pipe coupling in the hanging state is higher than the upper edge of the guard plate 21 on the discharge conveyor belt 20 to avoid interference during the rotation process.

[0050] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection created by this application.
