Description

Technical Field

[0001] The present invention relates to the technical field of pipe feeding, and particularly to a pipe feeding mechanism. Background Art

[0002] After many kinds of pipes are produced, they need to undergo subsequent processing, such as flaring, spraying, cutting, drilling, etc. When performing subsequent processing, the processing equipment needs to be equipped with a feeding mechanism. The feeding mechanism is responsible for separating a row of pipes into single pipes or groups of several pipes, and then feeding them into the processing equipment for processing. The pipes entering the processing equipment in groups of several need to be evenly spaced in order to meet the requirements of uniform processing of the processing equipment. When the existing feeding mechanism realizes the feeding of pipes in groups of several, it first places each pipe on the transfer rack separately, and then feeds several pipes on the transfer rack into the processing equipment together, with low efficiency.

[0003] Chinese Utility Model Patent CN207357986U (publication date: May 15, 2018) discloses an automatic feeding device for a pipe bender, including a frame, and further including a feeding chute provided on the frame for guiding pipes, and an automatic feeding mechanism provided on the feeding chute; the automatic feeding mechanism includes a rolling and sorting wheel provided in the feeding chute for transporting pipes, and further includes a driving assembly for driving the rolling and sorting wheel to rotate, and further includes a pushing component for pushing the pipes out of the outlet; the pushing component includes a plurality of lifting cylinders provided at the bottom of the outlet position of the feeding chute, and further includes a pushing plate provided on the piston rod of each lifting cylinder; each pushing plate is provided with a fixing groove for conveniently fixing the pipes; one end of the top of the feeding chute is provided with an opening, and a guiding plate is provided at the opening position and is inclined, and the lower end of the guiding plate is in contact with the upper end of the rolling and sorting wheel, and a storage plate is provided below the rolling and sorting wheel and is provided at the bottom of the feeding chute and is inclined. This patent arranges the pipes on the storage plate in sequence through the rotation of the rolling and sorting wheel, and then pushes the pipe at the outermost side of the storage plate out by the pushing plate and feeds it into the processing equipment. Therefore, this patent can only feed one pipe into the processing equipment at a time, and cannot arrange several pipes into a group with equal intervals. Summary of the Invention

[0004] The purpose of the present invention is to provide a pipe feeding mechanism with high efficiency that can evenly distribute pipes when feeding several pipes as a group.

[0005] To achieve the above object, the present invention provides a pipe loading mechanism, including a frame, a material rack, and a plurality of loading modules. One side of the material rack is connected to the long side of the frame. The plurality of loading modules are parallel and sequentially distributed along the length direction of the frame. The loading module includes a fixed support plate and a feeding plate. The fixed support plate is parallel to the feeding plate and both are arranged along the width direction of the frame. The feeding plate is arranged close to the material rack and is movably connected to the frame in the up and down direction. A plurality of support grooves are arranged on the fixed support plate along its length direction. The adjacent two support grooves are inclined and transitioned, and the inclination direction is downward from the side close to the material rack to the side far from the material rack. A plurality of feeding grooves are arranged on the feeding plate along its length direction. The adjacent two feeding grooves are inclined and transitioned, and the inclination direction is downward from the side close to the material rack to the side far from the material rack. The feeding grooves and the support grooves are arranged in a staggered manner.

[0006] As a preferred solution, the plurality of support grooves are continuously arranged on the fixed support plate, and the plurality of feeding grooves are continuously arranged on the feeding plate.

[0007] As a preferred solution, the distance between the bottom of the feeding groove and the side close to the material rack of its notch is greater than the distance between the bottom of the feeding groove and the side far from the material rack of its notch.

[0008] As a preferred solution, the cross-section of the support groove is an isosceles triangle, and the cross-section of the feeding groove is a triangle and the side close to the material rack is longer than the side far from the material rack.

[0009] As a preferred solution, the loading module further includes a movable support plate. The movable support plate is parallel to the fixed support plate and is movably connected to the frame in the up and down direction and in the width direction of the frame. A plurality of accommodating grooves are arranged on the movable support plate.

[0010] As a preferred solution, a plurality of adjacent support grooves form a support group. The number of support grooves in one support group is equal to the number of feeding grooves on the feeding plate. A plurality of support groups are arranged on the fixed support plate at uniform intervals along its length direction. A plurality of adjacent accommodating grooves form an accommodating group. The number of accommodating grooves in one accommodating group is equal to the number of support grooves in one support group. A plurality of accommodating groups are arranged on the movable support plate at uniform intervals along its length direction. The interval distance between two adjacent accommodating groups is equal to the interval distance between two adjacent support groups.

[0011] As a preferred solution, the feeding module further includes a first lifting cylinder, a second lifting cylinder and a moving cylinder. The first lifting cylinder and the second lifting cylinder are arranged vertically, the moving cylinder is arranged along the width direction of the rack, the material pushing plate is connected to the piston rod of the first lifting cylinder, the moving cylinder is connected to the piston rod of the second lifting cylinder, and the moving support plate is connected to the piston rod of the moving cylinder.

[0012] As a preferred solution, the top surface of the end of the fixed support plate away from the material rack is inclined downward.

[0013] As a preferred solution, limiting plates that can approach or move away from each other are provided at both ends of the material rack.

[0014] As a preferred solution, the material rack is inclined downward.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] In the present invention, by arranging the material pushing grooves on the material pushing plate and the support grooves on the fixed support plate in a staggered manner, during feeding, the material pushing plate close to the material rack is lifted upward to lift the pipe closest to the rack on the material rack. Since the pipe is a cylindrical shape that can roll by itself, when the pipe is lifted, it will roll from above the material pushing plate into the first material pushing groove closest to the material rack on the material pushing plate. At this time, the pipe moves a certain distance away from the material rack along the width direction of the rack. Then the material pushing plate descends to a position lower than the fixed support plate. Since the position of the fixed support plate remains unchanged, the pipe is located above the fixed support plate and does not continue to descend with the material pushing plate. Due to the staggered arrangement of the material pushing grooves and the support grooves, the pipe will roll from above the fixed support plate into the support groove and continue to move a certain distance away from the material rack along the width direction of the rack; when the material pushing plate rises again, the material pushing plate is higher than the fixed support plate, and the pipe lifted for the first time is lifted and is located between the first material pushing groove and the second material pushing groove close to the material rack. Since the transition between adjacent two material pushing grooves is inclined downward, the pipe lifted for the first time will roll into the second material pushing groove. At the same time, according to the above working principle, a pipe will enter the first material pushing groove of the material pushing plate again. Then the material pushing plate continues to descend to a position lower than the fixed support plate. The pipe lifted for the first time is located between the first support groove and the second support groove and rolls into the second support groove, and the pipe lifted for the second time rolls into the first support groove; by repeating the above actions, each pipe can be arranged in the support grooves of the fixed support plate in sequence. By setting the distance between the support grooves, the spacing of the pipe arrangement can be adjusted to achieve equal-spacing distribution of the pipes when several pipes are fed in a group. Moreover, the feeding mechanism of the present invention distributes the spacing of each pipe while feeding, with high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0025] In addition, in the description of the present invention, unless otherwise stated, the meaning of "a plurality" is two or more.

[0026] Such as Figures 1 to 4As shown in the figure, a pipe loading mechanism of a preferred embodiment of the present invention includes a frame 1, a material rack 2, and a plurality of loading modules. One side of the material rack 2 is connected to the long side of the frame 1. The plurality of loading modules are parallel and sequentially distributed along the length direction of the frame 1. The loading module includes a fixed support plate 3 and a material pushing plate 4. The fixed support plate 3 and the material pushing plate 4 are parallel and both arranged along the width direction of the frame 1. The material pushing plate 4 is arranged close to the material rack 2. The material pushing plate 4 is movably connected to the frame 1 in the up and down direction. A plurality of support grooves 301 are arranged on the fixed support plate 3 along its length direction. The adjacent two support grooves 301 are inclined and transitioned, and the inclination direction is downward from the side close to the material rack 2 to the side far from the material rack 2. A plurality of material pushing grooves 401 are arranged on the material pushing plate 4 along its length direction. The adjacent two material pushing grooves 401 are inclined and transitioned, and the inclination direction is downward from the side close to the material rack 2 to the side far from the material rack 2. The material pushing grooves 401 and the support grooves 301 are arranged in a staggered manner. In this embodiment, by arranging the material pushing grooves 401 on the material pushing plate 4 and the support grooves 301 on the fixed support plate 3 in a staggered manner, the material pushing grooves 401 are closer to the material rack 2 than the support grooves 301. During loading, the material pushing plate 4 close to the material rack 2 is lifted upward, and the pipe closest to the frame 1 on the material rack 2 is lifted. Since the pipe is a cylindrical shape that can roll autonomously, when the pipe is lifted, it will roll into the first material pushing groove 401 closest to the material rack 2 above the material pushing plate 4. At this time, the pipe moves a certain distance away from the material rack 2 along the width direction of the frame 1. Then the material pushing plate 4 descends to a position lower than the fixed support plate 3. Since the position of the fixed support plate 3 remains unchanged, the pipe is located above the fixed support plate 3 and does not continue to descend with the material pushing plate 4. Due to the staggered arrangement of the material pushing grooves 401 and the support grooves 301, the pipe will roll into the support groove 301 from above the fixed support plate 3 and continue to move a certain distance away from the material rack 2 along the width direction of the frame 1; when the material pushing plate 4 rises again, the material pushing plate 4 is higher than the fixed support plate 3, and the pipe lifted for the first time is lifted and located between the first material pushing groove 401 and the second material pushing groove 401 close to the material rack 2. Since the adjacent two material pushing grooves 401 are inclined downward, the pipe lifted for the first time will roll into the second material pushing groove 401. At the same time, according to the above working principle, a pipe will enter the first material pushing groove 401 of the material pushing plate 4 again. Then the material pushing plate 4 continues to descend to a position lower than the fixed support plate 3. The pipe lifted for the first time is located between the first support groove 301 and the second support groove 301 and rolls into the second support groove 301. The pipe lifted for the second time rolls into the first support groove 301; by repeating the above actions, each pipe can be arranged in the support grooves 301 of the fixed support plate 3 in sequence. By setting the distance between the support grooves 301, the spacing of the pipe arrangement can be adjusted to achieve equal-spacing distribution of the pipes when several pipes are loaded in a group. Moreover, the loading mechanism of this embodiment distributes the spacing of each pipe while loading, with high efficiency.Multiple loading modules are arranged in parallel at intervals, which can ensure that the pipes are located in the support grooves 301 of multiple parallel fixed support plates 3, enabling the pipes to have multiple support points and be stably placed.

[0027] In this embodiment, multiple support grooves 301 are continuously arranged on the fixed support plate 3, and multiple feeding grooves 401 are continuously arranged on the feeding plate 4, reducing the distance between two adjacent support grooves 301 and two adjacent feeding grooves 401, so that the pipes are already in the grooves when they roll, preventing the pipes from rolling out of the grooves, making the pipe positioning more accurate, and facilitating the processing of the support grooves 301 and the feeding grooves 401. Further, the distance between the bottom of the feeding groove 401 and the side of its notch close to the material rack 2 is greater than the distance between the bottom of the feeding groove 401 and the side of its notch far from the material rack 2, making the bottom of the feeding groove 401 closer to the side far from the material rack 2 and increasing the distance for the pipes to move along the width of the machine frame 1. Further, the cross-section of the support groove 301 in this embodiment is an isosceles triangle, and the cross-section of the feeding groove 401 is a triangle with the side closer to the material rack 2 longer than the side far from the material rack 2. The groove with a triangular cross-section can adapt to pipes of different diameters and can make the pipes be centered and stably placed when placed.

[0028] Further, the loading module further includes a moving support plate 5. The moving support plate 5 is parallel to the fixed support plate 3 and is connected to the machine frame 1 in a manner that it can move up and down and can move along the width direction of the machine frame 1. Multiple accommodating grooves 501 are provided on the moving support plate 5. The shape and spacing of the accommodating grooves 501 are the same as those of the support grooves 301. When the number of pipes placed on the fixed support plate 3 reaches the number required for the feeding of the processing equipment, the moving support plate 5 rises, lifts several pipes together, and moves along the width direction of the machine frame 1, moving these pipes away from the material rack 2, feeding these pipes into the processing equipment together or discharging them, so that the feeding plate 4 and the fixed support plate 3 can load materials again.

[0029] In this embodiment, multiple adjacent support grooves 301 form a support group. The number of support grooves 301 in a support group is equal to the number of feeding grooves 401 on the feeding plate 4. Multiple support groups are provided on the fixed support plate 3 at uniformly spaced intervals along its length direction. Multiple adjacent accommodating grooves 501 form an accommodating group. The number of accommodating grooves 501 in an accommodating group is equal to the number of support grooves 301 in a support group. Multiple accommodating groups are provided on the moving support plate 5 at uniformly spaced intervals along its length direction. The spacing distance between two adjacent accommodating groups is equal to the spacing distance between two adjacent support groups, enabling the moving support plate 5 to move the pipes in multiple support groups simultaneously, placing the pipes in each group into each support group in sequence, and realizing that the pipes in each group gradually move away from the material rack 2. When the first support group close to the material rack 2 is filled with pipes, the moving support plate 5 places this group of pipes into the second support group, enabling the loading die to work continuously.

[0030] Optionally, the loading module further includes a first lifting cylinder 6, a second lifting cylinder 7, and a moving cylinder 8. The first lifting cylinder 6 and the second lifting cylinder 7 are arranged vertically, and the moving cylinder 8 is arranged along the width direction of the frame 1. The material pushing plate 4 is connected to the piston rod of the first lifting cylinder 6, the moving cylinder 8 is connected to the piston rod of the second lifting cylinder 7, and the moving support plate 5 is connected to the piston rod of the moving cylinder 8. By extending and retracting the piston rods of the first lifting cylinder 6, the second lifting cylinder 7, and the moving cylinder 8, the rising and falling of the material pushing plate 4 and the moving support plate 5 and the movement of the moving support plate 5 are realized.

[0031] In addition, the top surface of the fixed support plate 3 of this embodiment, at the end far from the material rack 2, is inclined downward. When the pipe is located in the support groove 301 farthest from the material rack 2, the moving support plate 5 rises to lift the pipe. The moving support plate 5 moves a certain distance along the width direction of the frame 1 and then descends. When the pipe is located at the end of the fixed support plate 3 far from the material rack 2, it falls along the inclined surface there, realizing the unloading of the pipe from the frame 1. In addition, limit plates 9 that can approach or move away from each other are provided at both ends of the material rack 2. When multiple pipes are placed on the material rack 2, the two limit plates 9 approach each other to align the two ends of each pipe, preventing the two ends of the pipes from being uneven after loading. Further, the material rack 2 is inclined downward, so that the pipes can automatically roll to the side close to the frame 1 under the action of their own gravity, facilitating the loading of the material pushing plate 401, improving the efficiency, and simplifying the structure.

[0032] In summary, the embodiment of the present invention provides a pipe feeding mechanism, which is arranged by staggering the material feeding groove 401 on the material feeding plate 4 and the support groove 301 on the fixed support plate 3, so that the material feeding groove 401 is closer to the material rack 2 than the support groove 301. When feeding, the material feeding plate 4 close to the material rack 2 is lifted upward to lift the pipe closest to the frame 1 on the material rack 2. Since the pipe is a columnar material that can roll independently, when the pipe is lifted, it will roll from the top of the material feeding plate 4 into the first material feeding groove 401 of the material feeding plate 4 closest to the material rack. At this time, the pipe moves a distance away from the material rack 2 along the width direction of the frame 1, and then the material stripping plate 4 drops to a position below the fixed support plate 3. Since the position of the fixed support plate 3 remains unchanged, the pipe is located above the fixed support plate 3 and does not continue to drop with the material stripping plate 4. Since the material stripping groove 401 and the support groove 301 are misaligned, the pipe will roll into the support groove 301 from above the fixed support plate 3 and continue to move a distance away from the material rack 2 along the width direction of the frame 1; when the material stripping plate 4 rises again, the material stripping plate 4 is higher than the fixed support plate 3, the pipe lifted for the first time is lifted and located between the first material-dispensing groove 401 and the second material-dispensing groove 401 near the material rack 2. Since the two adjacent material-dispensing grooves 401 are inclined downwardly transitioned, the pipe lifted for the first time will roll into the second material-dispensing groove 401. At the same time, according to the above working principle, another pipe will enter the first material-dispensing groove 401 of the material-dispensing plate 4, and then the material-dispensing plate 4 will continue to descend to a position lower than the fixed support plate 3, and the pipe lifted for the first time will roll into the second material-dispensing groove 401. The pipe is located between the first support groove 301 and the second support groove 301 and rolls into the second support groove 301. The pipe lifted for the second time rolls into the first support groove 301. Repeating the above-mentioned actions, each pipe can be arranged in the support groove 301 of the fixed support plate 3 in sequence. By setting the distance between the support grooves 301, the spacing of the pipe arrangement can be adjusted to achieve equal spacing of the pipes when several pipes are loaded as a group. Moreover, the loading mechanism of this embodiment distributes the spacing of each pipe while loading, which is highly efficient.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
