[0034] Embodiment 1

[0035] Reference Figure 1 , Embodiment 1 of the present invention proposes a loading and unloading device, which includes: a loading rack 1, a unloading rack 6, a transmission mechanism 3 and a transfer mechanism 7, wherein the loading rack 1 is located on a first side of the transmission mechanism 3, and its first surface is used to place at least one pipe workpiece 5 to be processed, the transmission mechanism 3 corresponds to the working position 4 of the pipe workpiece 5, and has a transmission groove 311 for supporting the pipe workpiece 5, the unloading rack 6 is located on a second side opposite to the first side of the transmission mechanism 3, and its second surface is used to place the processed pipe workpiece 5, and the transfer mechanism 7 corresponds to the pipe workpiece 5. The work station 4 of the workpiece 5 is spaced apart from the transmission mechanism 3. The transfer mechanism 7 has a lifting portion 703 that can produce vertical displacement relative to the transmission mechanism 3. The number of the transfer mechanisms 7 is two groups, and at least the lifting portion 703 of one group of the transfer mechanisms 7 extends to the side where the loading rack 1 is located, and at least the lifting portion 703 of the other group of the transfer mechanisms 7 extends to the side where the unloading rack 6 is located. The two groups of transfer mechanisms 7 are used to realize the transfer of the tube workpiece 5 between the loading rack, the transmission mechanism 3 and the unloading rack 6.

[0036] Specifically, the tube workpiece 5 to be processed is placed on the upper side of the loading rack 1, and is transferred to the upper side of the transmission mechanism 3 by the transfer mechanism 7. After processing, it is transferred to the upper side of the unloading rack 6 by the transfer mechanism 7. The processed tube workpiece 5 is stored on the upper side of the unloading rack 6. Through the loading rack 1, the transfer mechanism 7, the transmission mechanism 3 and the unloading rack 6, flexible loading and unloading of the tube workpiece 5 can be achieved, which is convenient for processing the tube workpiece 5.

[0037] The transmission mechanism 3 is used to support the pipe workpiece 5, and the number of the transmission mechanism 3 is at least two, which can make the placement of the pipe workpiece 5 more stable and facilitate its processing. The multiple transmission mechanisms 3 do not interfere with the transfer mechanism 7, and are staggered with the transfer mechanism 7. The pipe workpiece 5 transferred to the upper side of the transmission mechanism 3 can be processed, such as threading operations; refer to the attached Figure 1 The work station 4 can be an area for processing the pipe workpiece 5, or the work station can also be a position on the same straight line as the area for processing the pipe workpiece 5, and the pipe workpiece 5 can be transported in a straight line to the area for processing through the transmission mechanism 3.

[0038] The lifting part 703 can be driven by the first driving part 701 to move in the vertical direction to realize the lifting function so as to transfer the pipe workpiece 5; the transfer mechanism 7 has two groups, each group can have two, one of which is the first transfer mechanism 71, and the other is the second transfer mechanism 72. The lifting part 703 of the first transfer mechanism 71 partially extends to the side where the loading rack 1 is located, so that the third surface of the lifting part 703 overlaps with the loading rack 1 in the horizontal direction, and the plane of the overlapping part can stably lift the pipe workpiece 5 to be transferred, so that the first transfer mechanism 71 can be lifted and lowered. The structure 71 can lift the pipe workpiece 5 smoothly from the upper side of the loading rack 1, and the lifting part 703 of the second transfer mechanism 72 partially extends to the side where the unloading rack 6 is located, so that the fourth surface of the lifting part 703 has an overlapping part with the unloading rack 6 in the horizontal direction, and overlaps with the unloading rack 6 in the horizontal direction. The plane of the overlapping part can smoothly put down the pipe workpiece 5 to be transferred, so that the processed pipe workpiece 5 can fall on the unloading rack 6, avoiding the pipe workpiece 5 from falling off axially during the transfer process, falling on the ground to cause damage or hurting surrounding staff.

[0039] The loading rack 1 and the unloading rack 6 can be but are not limited to a pair of rods. The upper side of the rod of the loading rack 1 is used to place the surface of the pipe workpiece 5 to be processed as the first plane, and the upper side of the rod of the unloading rack 6 is used to place the surface of the processed pipe workpiece 5 as the second plane. The rod is fixed to the ground by the support feet at the lower side thereof. The material of the rod can be but is not limited to stainless steel. The rod can be placed at an angle, and the inclination angle can be 5°. The loading rack 1 and the unloading rack 6 have a certain inclination angle, which can make the pipe workpiece 5 roll in the desired direction under the action of gravity, wherein the pipe workpiece 5 on the loading rack 1 rolls toward the side close to the transmission mechanism 3, which can make the loading rack The pipe workpieces 5 on the upper side of the loading rack 1 are placed closely to the side close to the transmission mechanism 3 in sequence, which is convenient for the transfer mechanism 7 to load the pipe workpieces 5. The pipe workpieces 5 on the upper side of the unloading rack 6 will roll to the side away from the transmission mechanism 3, so that the pipe workpieces 5 on the upper side of the unloading rack 6 can be closely to the side away from the transmission mechanism 3 in sequence, avoiding the pipe workpieces 5 stored on the upper side of the unloading rack 6 affecting the unloading of the transfer mechanism 7, and the upper surfaces of the loading rack 1 and the unloading rack 6 are smooth without obvious protrusions, which can avoid the pipe workpieces 5 from being scratched when rolling on the upper side; the loading rack 1 and the unloading rack 6 can also be composed of multiple rods, which are staggered with the lifting part 703 and do not affect the lifting of the lifting part 703.

[0040] When it is necessary to transfer the pipe workpiece 5 to the work station 4, the pipe workpiece 5 that is closest to the transmission mechanism 3 on the side of the loading rack 1 to be transferred to the transmission mechanism 3 for processing can be lifted by the lifting part 703 of the first transfer mechanism 71 in the transfer mechanism 7. The pipe workpiece 5 transferred at one time can be one or more, depending on the processing requirements and the capacity of the transmission mechanism 3. After being lifted, the pipe workpiece 5 rolls on the upper side of the lifting part 703 of the first transfer mechanism 71. When it rolls to the upper side of the transmission mechanism 3, the lifting part 703 of the first transfer mechanism 71 moves downward, and the pipe workpiece 5 is flexibly transferred to the transmission groove 311 of the transmission mechanism 3, which is supported by the transmission mechanism 3 to realize flexible loading of the pipe workpiece 5. When the processing of the pipe workpiece 5 is completed and the pipe workpiece 5 needs to be transferred to the unloading rack 6, the second The lifting part 703 of the transfer mechanism 72 rises to lift the pipe workpiece 5 from the supporting part. When the lifting part 703 of the second transfer mechanism 72 rises to the highest point, the pipe workpiece 5 will roll on the upper side of the lifting part 703 of the second transfer mechanism 72 as the lifting part 703 of the second transfer mechanism 72 rises, and roll to the side of the lifting part 703 of the second transfer mechanism 72 closest to the unloading rack 6. Then the lifting part 703 of the second transfer mechanism 72 descends, and the pipe workpiece 5 falls on the unloading rack 6, and is supported by the unloading rack 6 to achieve flexible unloading of the pipe workpiece 5. The flexible loading and unloading of the pipe workpiece 5 can greatly reduce the impact and collision received by the pipe workpiece 5 during the transportation process, protect the pipe workpiece 5, and avoid damage to the pipeline workpiece due to collision or impact during the production and transportation process, thereby reducing production efficiency and increasing production costs.

[0041] According to the above, an embodiment of the present invention proposes a loading and unloading device, which transfers the pipe workpiece 5 from the loading rack 1 to the transmission mechanism 3 through the lifting part 703 of the transfer mechanism 7, and then transfers it from the transmission mechanism 3 to the unloading machine, so that flexible loading and unloading of the pipe workpiece 5 can be achieved, and the problems of time-consuming and labor-intensive, low efficiency, safety hazards, and bumping against the workpiece when the pipe workpiece 5 is transported by using an overhead crane can be solved, so that the pipe workpiece 5 can be loaded and unloaded more time-saving and labor-saving, without safety hazards, and the impact and collision of the workpiece during transportation are minimized to the greatest extent, protecting the pipe workpiece 5 from damage, and the second driving part 34 in the transmission mechanism 3 can drive the transmission wheel 31 to rotate in the mounting part 32, driving the pipe fittings to move along the axis, without lifting the pipe workpiece 5 to move it, and also avoiding directly pushing the pipe workpiece 5 in the transmission groove 311, causing the pipe workpiece 5 to rub against the transmission groove 311 and cause scratches, and the axial position of the pipe workpiece 5 can be flexibly adjusted, which can facilitate workers to process it.

[0042] For further information, see Attachment Figure 2 In a specific implementation, the height of the upper surface of the lifting portion 703 gradually decreases from one end close to the loading rack 1 to one end close to the unloading rack 6, and a first stopper 702 is provided on the lifting portion 703 on the side where the loading rack 1 is located. When the tube workpiece 5 abuts against the first stopper 702 on the side surface close to the loading rack 1, the position of the tube workpiece 5 corresponds to the position of the transmission slot 311 in the vertical direction, and a second stopper 705 is provided on the lifting portion 703 on the side where the unloading rack 6 is located, at the end close to the unloading rack 6.

[0043] Specifically, the upper surface of the lifting part 703 is a plane for transporting the tube-like workpiece 5, wherein the upper surface of the lifting part 703 in the first transport mechanism 71 is the third surface, and the upper surface of the lifting part 703 in the second transport mechanism 72 is the fourth surface. The lifting part 703 can be but is not limited to a group of rods that can be lifted and lowered. Specifically, rods with smooth surfaces can be used to avoid scratching the tube-like workpiece 5. The cross-sectional shape of the rod can be circular, wherein the lifting part 703 of the first transport mechanism 71 partially extends to the side where the upper material rack 1 is located, so that the third surface and the first surface have an overlapping part in the horizontal direction, and the lifting part 703 of the second transport mechanism 72 partially extends to the side where the lower material rack 6 is located, so that the fourth surface and the second surface have an overlapping part in the horizontal direction; the lifting part 703 can be tilted at a certain angle toward the side of the lower material rack 6, and the tilt angle can be 5°, so that the tube-like workpiece 5 can roll on the upper side of the lifting part 703 under the action of its own gravity.

[0044] When the lifting part 703 of the first transfer mechanism 71 rises, at least one pipe workpiece 5 on the side of the loading rack 1 close to the transmission mechanism 3 can be lifted. After being lifted, the pipe workpiece 5 will roll from the upper side of the lifting part 703 of the first transfer mechanism 71 to the side of the transmission mechanism 3, and will be blocked by the first stopper 702 when reaching the first stopper 702, wherein the first stopper 702 can be but is not limited to an iron rectangular stopper, the first stopper 702 has a certain height, which can be higher than the diameter of the pipe workpiece 5, and has the function of preventing the pipe workpiece 5 from continuing to roll, so as to prevent the pipe workpiece 5 from rolling off the lifting part 703 of the first transfer mechanism 71, and the outer side of the first stopper 702 can be wrapped with a buffer layer, which can be made of sponge to provide buffering for the pipe workpiece 5 and the first stopper 702. The first stopper 702 is located just above the transmission slot 311 on the side close to the unloading rack 6, so that the tube workpiece 5 can fall into the transmission slot 311 when it descends; the second stopper 705 is located at the end of the lifting part 703 of the second transfer mechanism 72 close to the unloading rack 6. The second stopper 705 has a certain height, which can be higher than the diameter of the tube workpiece 5. It has the function of preventing the tube workpiece 5 from continuing to roll, thereby preventing the tube workpiece 5 from rolling off the lifting part 703 of the second transfer mechanism 72, so that the tube workpiece 5 can fall on the unloading rack 6 when it descends, and the outer side of the second stopper 705 is also wrapped with a buffer layer, which can be made of sponge, and can provide buffering for the tube workpiece 5 and the second stopper 705, so as to prevent the tube workpiece 5 from rolling and colliding with the second stopper 705 due to excessive speed and being damaged.

[0045] For further information, see Attachment Figure 2 In a specific implementation, the transfer mechanism 7 also includes: a guide portion 704 and a first driving portion 701, the driving end of the first driving portion 701 is supported on the bottom side of the lifting portion 703, and is used to drive the lifting portion 703 to move in a vertical direction, the guide portion 704 includes: a connecting member 7041 and a guide rail 7042 extending in a vertical direction, one end of the connecting member 7041 is connected to the lifting portion 703, and the connecting member 7041 is movably connected to the guide rail 7042.

[0046] Specifically, the first driving part 701 can be but not limited to a matching mechanism of a cylinder and a cylinder rod, the cylinder rod is inserted in the cylinder, the cylinder can drive the cylinder rod to move up and down, and the cylinder rod can push the lifting part 703 to move up and down when it moves up and down. The connecting piece 7041 in the guide part 704 can be but not limited to two rods, the upper ends of the rods are respectively assembled on both sides of the lifting part 703, and the lower ends of the rods are respectively inserted in the guide rails 7042 extending in the vertical direction. The matching of the connecting piece 7041 and the guide rail 7042 can be but not limited to a pair of linear bearings and a pair of guide rails 7042, which can limit the lifting part 703 and make it move only in the vertical direction, so as to avoid the center of gravity of the lifting part 703 changing when the pipe workpiece 5 rolls on the upper side of the lifting part 703, so that the first driving part 701 is subjected to a large lateral force, affecting the service life of the first driving part 701.

[0047] For further information, see Attachment Figure 4 In a specific implementation, the transmission mechanism 3 includes: a mounting portion 32, a transmission wheel 31 and a second driving portion 34, the transmission wheel 31 is movably mounted on the mounting portion 32, the second driving portion 34 is mounted on the mounting portion 32, the driving end of the second driving portion 34 is connected to the transmission wheel 31, and is used to drive the transmission wheel 31 to rotate. When the transmission wheel 31 supports the tubular rod, the direction of the rotation axis of the transmission wheel 31 is perpendicular to the axial direction of the tubular rod.

[0048] Specifically, the axial direction of the pipe workpiece 5 is perpendicular to the transfer direction, the axial direction of the transmission wheel 31 is perpendicular to the axial direction of the pipe workpiece 5, the transmission wheel 31 is movably installed in the mounting portion 32, the transmission wheel 31 can rotate in the mounting portion 32, and the transmission wheel 31 is driven to rotate by the second driving portion 34, so that the transmission wheel 31 can support the pipe workpiece 5 while also driving the pipe workpiece 5 to make axial displacement in the axial direction through its own rotation, so that the workers at the workstation 4 can adjust the axial position of the pipe workpiece 5 and / or transmit the pipe workpiece 5 to facilitate the processing of the pipe workpiece 5, and the adjustment process is a flexible process, and there is no need to lift and then put down the pipe workpiece 5, which can make the adjustment process safer, avoid the pipe workpiece 5 from being damaged by bumps and impacts during the lifting and lowering process, and save workers' physical strength.

[0049] For further information, see Attachment Figure 4 In a specific implementation, the mounting portion 32 includes an adjusting member 33 and a mounting seat, the mounting seat is used to mount the transmission wheel 31, the mounting seat is arranged at the upper end of the adjusting member 33, and the adjusting member 33 is used to adjust the height of the mounting seat.

[0050] Specifically, the adjusting member 33 can be, but is not limited to, a support rod with adjustable height, which can support the mounting seat and adjust the height of the mounting seat within the lifting range of the lifting part 703, making it more convenient for workers to process the pipe workpiece 5. The mounting part 32 can be, but is not limited to, a bracket, specifically a "U"-shaped bracket, including a horizontal plate and two vertical side plates. The horizontal plate is arranged on the adjusting member 33, and the transmission wheel 31 is rotationally assembled in the side plates through bearings, enabling the transmission wheel 31 to rotate therein, so that the transmission wheel 31 can drive the pipe workpiece 5 and drive the pipe workpiece 5 to move along its axial direction.

[0051] Further, referring to the attached Figure 4 , in a specific implementation, the transmission groove 311 is circumferentially arranged in the middle of the transmission wheel 31, and the width of the transmission groove 311 gradually decreases from the outside to the inside.

[0052] Specifically, the transmission groove 311 can be an arc-shaped groove circumferentially arranged in the middle of the transmission wheel 31, which can support and stabilize the pipe workpiece 5, enabling the pipe workpiece 5 to be stably placed in the transmission wheel 31 and preventing it from slipping in the axial direction of the transmission wheel 31. Alternatively, more preferably, the transmission groove 311 can also be a V-shaped groove circumferentially arranged in the middle of the transmission wheel 31. The V-shaped groove can adapt to pipe workpieces 5 with different diameters, with a wider adaptability and greater practicality.

[0053] Further, referring to the attached Figure 2 , in a specific implementation, the second driving part 34 includes a motor 343, a driving wheel 344, a transmission belt 342, and a driven wheel 341. The driven wheel 341 is arranged on the outer rotating shaft of the transmission wheel 31. The driven wheel 341 and the driving wheel 344 are driven by the transmission belt 342, and the driving wheel 344 is arranged on the output shaft of the motor 343.

[0054] Specifically, the motor 343 can drive the driving wheel 344 to rotate. The transmission belt 342 and the driven wheel 341 transmit the power to the rotating shaft of the transmission wheel 31, driving the transmission wheel 31 to rotate, so that the transmission wheel 31 can drive the pipe workpiece 5 above it to move in the axial direction, facilitating the worker to adjust the pipe workpiece 5 in the axial direction. The adjustment process is time-saving and labor-saving, with higher efficiency, which can improve production efficiency, achieve flexible adjustment of the pipe workpiece 5 on its axis, and avoid the pipe workpiece 5 from being bumped or impacted when axially adjusting the pipe workpiece 5, thereby protecting the pipe workpiece 5.

[0055] Further, referring to the attached Figure 2 , in a specific implementation, the height of the first surface gradually increases from the end close to the transfer mechanism 7 to the other end, and a first baffle 8 is arranged at the end of the first surface close to the transfer mechanism 7.

[0056] Specifically, the upper surface of the loading rack 1 is the first surface, which is used to store the pipe workpiece 5 to be processed. The end of the first surface away from the transmission mechanism 3 is higher than the end close to the transmission mechanism 3. The first surface is a continuous inclined plane, and its inclination angle can be 5°, so that the first surface can support the pipe workpiece 5 while allowing the pipe workpiece 5 to roll in the direction of the transmission mechanism 3 in sequence. The pipe workpiece 5 is limited by the first baffle 8 to prevent the pipe workpiece 5 from sliding off the loading rack 1. A shock-absorbing jacket can be wrapped on the outside of the first baffle 8. The shock-absorbing jacket can be but not limited to a sponge pad, which can cushion the pipe workpiece 5 sliding toward the first baffle 8 to prevent the pipe workpiece 5 from colliding with the first baffle 8 and being damaged, thereby saving production costs.

[0057] For further information, see Attachment Figure 3 In a specific implementation, the height of the second surface gradually decreases from one end close to the transfer mechanism 7 to the other end, and a second baffle 9 is provided at one end of the second surface away from the transfer mechanism 7.

[0058] Specifically, the upper surface of the unloading rack 6 is the second surface, and the second surface is used to store the processed pipe workpieces 5. The end of the second surface close to the transmission mechanism 3 is higher than the end away from the transmission mechanism 3. The second surface is a continuous inclined plane, and its inclination angle can be 5°, so that the processed pipe workpieces 5 can roll on the second surface. The second baffle 9 has a certain height, which can prevent the pipe workpieces 5 from continuing to roll and stop them at the position of the second baffle 9. The pipe workpieces 5 falling from the second lifting part will roll to the position of the second baffle 9 instead of staying in place, so that the processed pipe workpieces 5 stored on the second surface will not affect the placement of new processed pipe workpieces 5, and the outer side of the second baffle 9 can be wrapped with a shock-absorbing jacket. The shock-absorbing jacket can be but not limited to a sponge pad, which can cushion the pipe workpiece 5 sliding toward the second baffle 9 to prevent the pipe workpiece 5 from colliding with the second baffle 9 and being damaged, thereby saving production costs.

[0059] For further information, see Attachment Figure 2 In a specific implementation, the number of the tube workpieces 5 to be processed is at least two, and a blocking mechanism 2 is provided at one end of the first surface close to the transfer mechanism 7. The blocking mechanism 2 has a telescopic end that can extend vertically out of the upper side of the first surface or shorten to the lower side of the first surface. When the telescopic end is extended, it is used to limit the tube workpieces 5 other than at least one tube workpiece 5 close to one end of the transfer mechanism 7 to roll toward the side where the transfer mechanism 7 is located.

[0060] Specifically, when the rod of the loading rack 1 is inclined at a certain angle, and the number of the pipe workpieces 5 placed on the upper side of the loading rack 1 is greater than the number of the pipe workpieces 5 transferred by the transfer mechanism 7 at one time, a blocking mechanism 2 can be set on the loading rack 1 to block the pipe workpieces 5 that do not need to be transferred for this processing to prevent them from affecting the pipe workpieces 5 in transfer; the number of blocking mechanisms 2 is more than 2, which are symmetrically arranged on both sides of the axial direction of the pipe workpiece 5 to prevent the pipe workpiece 5 from tilting. The blocking mechanism 2 can be but is not limited to a matching structure of a cylinder and a gas rod. The gas rod is inserted into the cylinder, and the cylinder can drive the gas rod to move up and down. The maximum extension height of the gas rod can be determined according to the diameter of the pipe workpiece 5. Adjustment is made so that when the gas rod is extended, the tube workpiece 5 can be prevented from rolling toward the transmission mechanism 3. The blocking mechanism 2 is arranged in the loading rack 1, and the horizontal position can be adjusted according to the diameter of the tube workpiece 5. When the gas rod is extended, the tube workpiece 5 can be limited, so that at least one tube workpiece 5 closest to one end of the transfer mechanism 7 does not roll toward the side of the transfer mechanism 7, and the lifting part 703 will not be disturbed by other tube workpieces 5 when transferring at least one tube workpiece 5 to be processed. When transferring the tube workpiece 5, the gas rod is extended, and after completing the transfer of the tube workpiece 5 once, the gas rod is retracted to make the tube workpiece 5 roll toward the side of the transfer mechanism 7 to prepare for the next transfer.
