Description

Technical Field

[0001] The present invention relates to the technical field of pipe production, and in particular to a pipe rapid stacking device and a stacking method. Background Art

[0002] After the plastic pipe is extruded and cut into sections, the pipe needs to be placed on a shipping rack for stacking and shipping. At present, the production line mostly uses manual handling to transport the cut pipes to the transfer rack, but the workload of manual handling is large and it is easy to cause work-related accidents. Patent 201721294776.4 discloses a round tube stacking device, which uses a layer conveyor belt to collect single-layer round tubes. After reaching the required number, the conveying arm moves forward, the lifting silo moves up to the required position, and the layer conveyor belt rotates to make the round tube roll onto the conveying arm, and then the conveying arm is withdrawn to achieve effective stacking of the round tube. The stacking device can directly transfer the single-layer round tube to the lifting silo through the conveying arm by horizontal movement; but the device places the round tube in the silo through the conveying arm, and the position of the round tube on the conveying arm is not fixed, making the stacked round tubes uneven, and in the stacking device, the round tube is connected by the lifting silo, the silo and the stacking device are integrated, and a separate shipping rack is required to transfer the round tube, which is inconvenient to use. Summary of the invention

[0003] The object of the present invention is to provide a rapid pipe stacking device, which can efficiently and rapidly stack the cut pipes on a transfer vehicle through automatic control, thereby improving the overall efficiency of the pipe production line.

[0004] The present invention provides a rapid pipe stacking device, comprising:

[0005] Transfer racks for loading pipes;

[0006] A trusteeship mechanism for collecting pipes in rows, the trusteeship mechanism comprising a rotating assembly and a support member for receiving the pipes, the rotating assembly being connected to the support member to drive the support member to rotate;

[0007] A stacking mechanism for clamping pipes in rows and placing the rows of pipes on the transfer rack, the stacking mechanism comprising the pipe clamping assembly and the lifting assembly;

[0008] The pipe clamping assembly includes a driving assembly and two symmetrically arranged clamping assemblies, wherein the driving assembly is connected to the clamping assembly to drive the clamping assembly to reciprocate along the axial direction of the pipe to clamp or loosen the pipe;

[0009] A lifting assembly is connected to the tube clamping assembly to drive the tube clamping assembly to move up and down.

[0010] The cut pipes are collected on the support through the trusteeship mechanism. After a certain number of pipes are collected, the pipe clamping assembly clamps the pipes on the support from both ends, and under the action of the lifting assembly, the clamped pipes are driven to move to the transfer rack, and the pipes are placed on the transfer rack. By placing the pipes multiple times, the pipes are stacked on the transfer vehicle. The mechanized trusteeship mechanism, pipe clamping assembly and lifting assembly are used to realize the mechanized stacking and transfer of the pipes, replacing the manual operation in the prior art. It is easy to use, reduces the output of labor, and improves the efficiency of stacking and loading.

[0011] Furthermore, the clamping assembly includes a clamping member, and the driving assembly is connected to the clamping member to drive the clamping member to move back and forth along the axial direction of the pipe. The pipe is clamped from both ends by the clamping force of the two opposing clamping members. The specific clamping member can be a rectangular body, an L-shaped plate, or other shapes.

[0012] Furthermore, a plurality of positioning protrusions are arranged in parallel on the clamping member, and the end of the positioning protrusion away from the clamping member can be inserted into the pipe. By arranging the positioning protrusions on the clamping member, when clamping the pipe, the positioning protrusions can extend into the pipe mouth of the pipe, thereby improving the clamping stability, clamping the pipe under a relatively small clamping force, and preventing the pipe from falling off the clamping assembly during the lifting process, thereby improving the operation stability.

[0013] Furthermore, the positioning protrusion is in the shape of a cone, and the end with a larger radius of the positioning protrusion is connected to the clamping member, while the end with a smaller radius of the positioning protrusion abuts against the pipe mouth of the pipe. The positioning protrusion is set to be in the shape of a cone, and the end with a smaller radius is used to position the pipe. During use, when the pipe mouth of the pipe is not aligned with the positioning protrusion, during the clamping process, the pipe will move radially under the squeezing action of the clamping component, so that the positioning protrusion enters the pipe mouth of the pipe, and the pipe can be automatically positioned when the pipe is clamped. In addition, the positioning protrusion is set to be in the shape of a cone, and can also be used for pipes of different radii, so that during the clamping process, the positioning protrusion can abut against pipes of different radii, ensuring that the clamping component can clamp the pipe when clamping pipes of different radii.

[0014] Furthermore, the pipe clamping assembly also includes a first mounting plate, a second mounting plate and a second driving assembly, the first mounting plate is connected to the lifting assembly, the second mounting plate is slidably connected to the first mounting plate, the clamping member and the driving assembly are both arranged on the second mounting plate, the second driving assembly is arranged on the first mounting plate, and the second driving assembly is connected to the second mounting plate to drive the second mounting plate to slide. The second driving assembly can drive the second mounting plate to slide on the first mounting plate. When stacking pipes, since the pipes are cylindrical, the two layers of pipes are staggered, which can make the stacked pipes more neat and stable. During the stacking process, the second driving assembly drives the clamping member installed on the first mounting plate to move radially along the pipes, so that the upper layer of pipes and the lower layer of pipes are staggered, making the pipes more neatly stacked.

[0015] Furthermore, the lifting assembly includes a servo motor and a screw rod, the output end of the servo motor is connected to the screw rod, and the tube clamping assembly is connected to the screw rod. The servo motor rotates forward and reversely to drive the screw rod to rotate forward and reversely, and the tube clamping assembly is connected to the screw rod, and the forward and reverse rotation of the screw rod drives the lifting and lowering of the tube clamping assembly.

[0016] Furthermore, the rotating assembly includes a frame, a cylinder, a rotating shaft, and a push rod arranged on the frame; the output end of the cylinder is hinged to one end of the push rod, the other end of the push rod is fixedly connected to the rotating shaft, and the rotating shaft is fixedly connected to one end of the support member. The extension and retraction of the output end of the cylinder drives the push rod to rotate, and then drives the rotating shaft to rotate, and the support member also rotates accordingly. By driving the support member to rotate through the cylinder, the support member can be quickly rotated to the corresponding position, thereby improving work efficiency.

[0017] Furthermore, there are at least two trusteeship mechanisms, which are arranged at intervals along the axial direction of the pipe. The two trusteeship mechanisms are respectively arranged at both ends of the pipe to increase the stability of the support member in supporting the pipe.

[0018] Furthermore, the support member is in the shape of a thin strip, and a stopper is protruded from one end of the support member away from the rotating assembly. The support member is in the shape of a thin strip, such as a tube or a plate, which can reduce the force of rotating the support member and improve the rotation efficiency.

[0019] A second object of the present invention is to provide a method for rapid stacking of pipes, based on the above-mentioned stacking device, comprising the following steps:

[0020] (a) placing the transfer rack in the pipe collection area, and the cut pipes fall into the support of the trusteeship mechanism in sequence;

[0021] (b) when the number of pipes on the support reaches a preset value, the driving assembly drives the clamping assembly to clamp the pipes on the support;

[0022] (c) the lifting assembly drives the pipe clamping assembly and the pipe clamped therein to rise a distance D0 from the initial position and then stop;

[0023] (d) the rotating assembly drives the supporting member to rotate so that the supporting member leaves the bottom of the clamped pipe;

[0024] (e) The lifting assembly drives the clamping assembly and the clamped pipe to descend a distance D1 from the initial position, and the lowest end of the clamped pipe contacts the storage surface of the transfer rack. The driving assembly drives the clamping assembly to release the clamped pipe, so that the first layer of pipes is formed on the transfer rack where the clamped pipe is placed;

[0025] (f) the lifting assembly drives the clamping assembly to rise to an initial position;

[0026] (e) the rotating assembly drives the supporting member to rotate to an initial position;

[0027] (g) the cut pipe starts to fall onto the support again and step (b) is repeated;

[0028] (h) The second driving assembly drives the clamping assembly and the clamped pipe to slide a distance S from the initial position in the horizontal plane and along the radial direction of the pipe and then stop, and then repeat the above steps (c)-(e) to form a second layer of pipes; after step (e), the clamping assembly slides to the initial position;

[0029] Repeat the above steps until the transfer rack is filled with pipes and the nth layer of pipes is formed, wherein the distance the pipe clamping assembly descends when forming the second layer of pipes is D2, the distance the pipe clamping assembly descends when forming the third layer of pipes is D3, and the distance the pipe clamping assembly descends when forming the nth layer of pipes is Dn. D1 to Dn are a decreasing arithmetic progression, and the tolerance of the progression is the diameter of the pipe; s is the radius of the pipe.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] In the pipe stacking device of the present invention, the pipes after cutting are collected on the support through the trusteeship mechanism. After a certain number of pipes are collected, the pipe clamping assembly clamps the pipes on the support, and under the action of the lifting assembly, drives the clamped pipes to move to the transfer rack, and places the pipes on the transfer rack. By placing the pipes multiple times, the pipes are stacked on the transfer vehicle. The mechanized trusteeship mechanism, the pipe clamping assembly and the lifting assembly are used to realize the mechanized stacking and transfer of the pipes, replacing the manual operation in the prior art. It is easy to use, reduces the output of labor, and improves the stacking and loading efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present invention will be described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0043] Example 1: See attached Figure 1-8

[0044] A rapid stacking device for pipes comprises: a transfer rack 4 for loading pipes, and a trusteeship mechanism 1, wherein the trusteeship mechanism 1 is used to collect pipes in rows, and the transfer rack 4 is placed under the pipes collected in rows; Figure 1 As shown, the trusteeship mechanism 1 includes a rotating assembly 11 and a support member 12 for receiving the pipe, and the rotating assembly 11 is connected to the support member 12 to drive the support member 12 to rotate; specifically, in this embodiment, the rotating assembly 11 includes a frame 111, as shown in the attached Figure 8 As shown, a cylinder 112 and a rotating shaft 113 are arranged on the frame 111, wherein the rotating shaft 113 is fixed on the frame 111 through a bearing, the rotating shaft 113 is fixedly connected to one end of the support member 12, the output end of the cylinder 112 is hinged to one end of a push rod 114, and the other end of the push rod 114 is fixedly connected to the rotating shaft 113. The output end of the cylinder 112 is extended and retracted, driving the push rod 114 to rotate, and then driving the rotating shaft 113 to rotate, and the support member 12 also rotates accordingly. The support member 12 is driven to rotate by the cylinder 112, so that the support member 12 can be quickly rotated to the corresponding position, thereby improving work efficiency. In other embodiments of the present invention, the rotating assembly 11 can also be a combination of a servo motor, a reduction box, gears, etc., with the servo motor as the power source to drive the support member 12 to rotate.

[0045] The stacking mechanism is used to clamp the rows of pipes from the support 12 and place them on the transfer rack 4. Specifically, the stacking mechanism includes a pipe clamping assembly 2 and a lifting assembly 3. Figure 6 As shown, the clamping assembly 2 includes a driving assembly 21 and two symmetrically arranged abutting assemblies 22, the driving assembly 21 is connected to the abutting assemblies 22 to drive the abutting assemblies 22 to clamp or loosen the pipe; specifically, the abutting assembly 22 includes a clamping member 221, the driving assembly 21 is connected to the clamping member 221 to drive the clamping member 221 to reciprocate along the axial direction of the pipe. The clamping member 221 is provided with a plurality of positioning protrusions 222 in parallel, and the end of the positioning protrusion 222 away from the clamping member 221 can be inserted into the pipe. The pipe is clamped by the clamping forces of two opposite clamping members 221. A positioning protrusion 222 is provided on the clamping member 221. By providing the positioning protrusion 222 on the clamping member 221, when the pipe is clamped, the positioning protrusion 222 can extend into the pipe mouth of the pipe, thereby improving the clamping stability. The pipe can be clamped under a smaller clamping force, and the pipe will not fall off the clamping component 22 during the lifting process, thereby improving the operation stability.

[0046] It should be noted that in other embodiments of the present invention, the clamping member 221 can be used alone as the clamping member 22. Under the action of the driving member 21, the two opposite clamping members 221 respectively clamp the two ends of the pipe to achieve the clamping of the pipe. More specifically, the clamping member 221 can be a rectangular body, an L-shaped plate, or other shapes that can be used to clamp the pipe. In the present invention, the driving member 21 can be a combination of a cylinder 112, a servo motor, and a gear. Preferably, in this embodiment, the driving member 21 is a cylinder 112, and the output end of the cylinder 112 is fixedly connected to the clamping member 221. The clamping member 221 is driven to move by the expansion and contraction of the output end of the cylinder 112.

[0047] In this embodiment, the positioning protrusion 222 is fixedly connected to the clamping member 221. In other embodiments of the present invention, the positioning protrusion 222 may be detachably connected to the clamping member 221. For pipes with different inner diameters, corresponding positioning protrusions 222 may be replaced, and the intervals between adjacent positioning protrusions 222 may be reasonably adjusted, so that the stacking device of the present invention can be suitable for pipes with different inner diameters.

[0048] A lifting assembly 3, wherein the lifting assembly 3 is connected to the tube clamping assembly 2 to drive the tube clamping assembly to be lifted or lowered. Specifically, in the present embodiment, the lifting assembly 3 comprises a servo motor 31 and a screw 32, wherein the output end of the servo motor 31 is connected to the screw 32, and the tube clamping assembly 2 is connected to the screw 32. The servo motor 31 rotates forward and reversely to drive the screw 32 to rotate forward and reversely, and the tube clamping assembly 2 is connected to the screw 32. The forward and reverse rotation of the screw 32 drives the tube clamping assembly 2 to be lifted or lowered. In other embodiments of the present invention, the lifting assembly 3 may also be other lifting assemblies 3 in the prior art, such as a scissor arm lifting assembly 3, etc.

[0049] When the stacking device of this embodiment is used to stack pipes, the trusteeship mechanism 1 is placed at the discharge port of the cutting machine, and the cut pipes fall onto the trusteeship mechanism 1. The cut pipes are collected on the support member 12 through the support member 12 of the trusteeship mechanism 1. After a certain number of pipes are collected, the two symmetrical clamping components 22 in the pipe clamping component 2 clamp the pipes on the support member 12 under the drive of the driving component 21, and drive the clamped pipes to move toward the transfer rack 4 under the action of the lifting component, and place the pipes on the transfer rack 4. By placing the pipes multiple times, the pipes are stacked on the transfer vehicle; the mechanized trusteeship mechanism 1, the pipe clamping component 2 and the lifting component 3 are used to realize mechanized stacking and transfer of pipes, replacing the manual operation in the prior art. It is easy to use, reduces the output of labor, and improves the efficiency of stacking and loading.

[0050] In other embodiments of the present invention, the loading assembly in patent document 201721294776.4 can also be used to transport the pipe at the discharge port to the support 12. Specifically, the loading assembly includes a conveying wheel, a conveyor belt arranged on the conveying wheel, and a pulling tooth arranged on the outer surface of the conveyor belt and used to lift the pipe upward. The pulling tooth is a plate-shaped hook. The pipe is lifted by the pulling tooth, and the pipe is transported to the support 12 under the action of the conveyor belt.

[0051] Preferably, in the above embodiment, the positioning protrusion 222 is in the shape of a cone, as shown in the accompanying drawings, the end of the positioning protrusion 222 with a larger radius is connected to the clamp 221, and the end of the positioning protrusion 222 with a smaller radius is in contact with the pipe mouth of the pipe. The positioning protrusion 222 is set to be in the shape of a cone, and the end with a smaller radius is used to position the pipe. When in use, when the pipe mouth of the pipe is not aligned with the positioning protrusion 222, during the clamping process, the pipe will move radially under the extrusion of the clamping component 22, so that the positioning protrusion 222 enters the pipe mouth of the pipe, and the pipe can be automatically positioned when the pipe is clamped. And the positioning protrusion 222 is set to be in the shape of a cone, and it can also be used for pipes of different radii, so that during the clamping process, the positioning protrusion 222 can be pressed against pipes of different radii, ensuring that when clamping pipes of different radii, the clamping component 22 can clamp the pipe. In other embodiments of the present invention, the positioning protrusion 222 can also be cylindrical, thin strip-shaped, or other shapes that can be inserted into the pipe mouth, but it should be noted that the radius of the end of the positioning protrusion 222 close to the pipe should be smaller than the inner diameter of the pipe.

[0052] Embodiment 2:

[0053] On the basis of Example 1, in this embodiment, specifically, as shown in the accompanying drawings, the tube clamping assembly 2 also includes a first mounting plate 23, a second mounting plate 24 and a second driving assembly 25, the first mounting plate 23 is connected to the lifting assembly, the second mounting plate 24 is slidably connected to the first mounting plate 23, the clamping member 221 and the driving assembly 21 are both arranged on the second mounting plate 24, the second driving assembly 25 is arranged on the first mounting plate 23, and the second driving assembly 25 is connected to the second mounting plate 24 to drive the second mounting plate 24 to slide. In this embodiment, a slide rail is provided on the first mounting plate 23, and a matching slide groove is provided on the second mounting plate 24. Under the action of the second driving assembly 25, the second mounting plate 24 can be driven to slide radially along the pipe in a horizontal plane; when stacking pipes, since the pipes are cylindrical, the two layers of pipes are staggered and stacked, which can make the stacked pipes more neat and stable. During the stacking process, the second driving assembly 25 is used to drive the clamping member 221 installed on the first mounting plate 23 to move radially along the pipe, so that the upper layer of pipes and the lower layer of pipes are staggered, making the pipes more neatly stacked.

[0054] It should be noted that, in this embodiment, the second drive assembly 25 can be a cylinder 112, the output end of the cylinder 112 is fixedly connected to the second mounting plate 24, and the second mounting plate 24 is driven to slide by the extension and contraction of the output end. In other embodiments of the present invention, the second drive assembly 25 can also be a combination of a servo motor and a reducer, gears, etc., to drive the second mounting plate 24 to slide.

[0055] Preferably, in Embodiment 1 and Embodiment 2, there are at least two trusteeship mechanisms 1, and the trusteeship mechanisms 1 are spaced apart along the axial direction of the pipe. The two trusteeship mechanisms are respectively arranged at both ends of the pipe to increase the stability of the support member 12 in supporting the pipe. There are also two lifting assemblies 3, and the two lifting assemblies 3 are respectively connected to the tightening assemblies 22. In other embodiments of the present invention, the two tightening assemblies 22 can share one lifting assembly 3. When there are two trusteeship mechanisms and two lifting assemblies 3, the positions of the two trusteeship mechanisms, as well as the positions of the two lifting assemblies 3 and the tightening assemblies 22 can be adjusted arbitrarily to suit pipes of different lengths.

[0056] In the present invention, in order to facilitate the unloading of pipes and to arrange them tightly on the support 12, the support can be set to be slightly inclined. When the pipes fall into the support 12, they can roll to one end of the support under the action of their own gravity. When the support is full of pipes, all the pipes are automatically arranged tightly on the support 12.

[0057] In Embodiment 1 and Embodiment 2, the support member 12 is in the shape of a thin strip, specifically a cylindrical shape, and a stopper is provided at one end of the support member 12 away from the rotating assembly 11. The support member 12 is in the shape of a thin strip, such as a tube or a plate, which can reduce the force of rotating the support member 12 and improve the rotation efficiency.

[0058] In the present invention, the PCL in the prior art controls the drive assembly 21, the cylinder 112, the servo motor 31, etc., to achieve automatic control of the entire palletizing process.

[0059] For the palletizing device of Example 2, a method for rapid palletizing of pipes is provided, comprising the following steps:

[0060] (a) placing the transfer rack 4 in the pipe collection area, and the cut pipes fall from the discharge port onto the support 12 of the trusteeship mechanism 1 in sequence and are arranged in rows;

[0061] (b) After the number of pipes on the support 12 reaches a preset value, the driving assembly 21 drives the clamping assembly 22 to clamp the pipes on the support 12; wherein, the preset value of the number of pipes can be determined based on the radius of the pipes and the capacity of the transfer rack 4; and the number of pipes on the support 12 can be counted by setting a counting device in the prior art at the discharge port.

[0062] (c) The lifting assembly 3 drives the pipe clamping assembly 2 and the pipe clamped therein to rise a distance D0 from the initial position and then stop. In this step, the pipe is raised a certain distance to make way for the rotation of the support member 12.

[0063] (d) The rotating assembly 11 drives the support member 12 to rotate so that the support member 12 leaves the bottom of the clamped pipe. As shown in the accompanying drawings, since the transfer rack 4 is located directly below the support member 12, only when the support member 12 rotates to be flush with the pipe can the pipe be lowered onto the transfer rack 4 under the action of the lifting assembly 3;

[0064] (e) The lifting assembly 3 drives the clamping assembly 2 and the clamped pipe to descend a distance D1 from the initial position, and the lowest end of the clamped pipe contacts the storage surface of the transfer rack 4. The driving assembly 21 drives the clamping assembly 22 to release the clamped pipe, so that the first layer of pipes is formed on the transfer rack 4 where the clamped pipe is placed;

[0065] (f) the lifting assembly 3 drives the clamping assembly 2 to rise to the initial position;

[0066] (e) The rotating assembly 11 drives the support member 12 to rotate to the initial position; in actual use, after the clamped pipe falls to the plane where the support member 12 is located, the rotating assembly 11 can rotate the support member 12 back to the initial position to improve the stacking efficiency.

[0067] (g) the cut pipe starts to fall onto the support member 12 again, and step (b) is repeated;

[0068] (h) The second driving assembly 25 drives the clamping assembly 22 and the clamped pipe to slide a distance S from the initial position in the horizontal plane and along the radial direction of the pipe and then stop, so that the upper pipe and the lower pipe are misaligned, and then the above steps (c)-(e) are repeated to form a second layer of pipes; after step (e), the clamping assembly 22 slides to the initial position;

[0069] Repeat the above steps until the transfer rack 4 is filled with pipes and the nth layer of pipes is formed, wherein the distance the pipe clamping assembly 2 descends when forming the second layer of pipes is D2, the distance the pipe clamping assembly 2 descends when forming the third layer of pipes is D3, and the distance the pipe clamping assembly 2 descends when forming the nth layer of pipes is Dn. D1 to Dn are a decreasing arithmetic progression, and the tolerance of the progression is the diameter of the pipe; s is the radius of the pipe.

[0070] In the present invention, the control system in the prior art is used to control the components in the palletizing device to perform corresponding steps to achieve the palletizing process.

[0071] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
