[0002] After the welded pipe is processed, in order to facilitate the transportation and movement of the welded pipe, it is often necessary to pack multiple welded pipes into a structure with a hexagonal, rectangular or other shape in cross section.

[0003] Welded pipes are often packaged according to their cross-sections. Robots are needed to move and stack the pipes. These robots typically grab the outer walls of the pipes, which can sometimes create large gaps between any two adjacent pipes and affect the packaging effect. Summary of the Invention

[0008] The placement plate is used to place the welded pipe, and the placement plate is located below the end of the horizontal transmission mechanism;

[0009] The horizontal moving mechanism is mounted on the frame and is used to drive the placement plate to move horizontally, so that the welded pipes sliding out of the horizontal transmission mechanism can fall on a specific position of the horizontal placement plate so that any two adjacent welded pipes are in close contact. Specifically, the horizontal transmission mechanism can be a structure in the prior art that can drive components to move horizontally, such as an electric cylinder, a screw slider mechanism, or an air cylinder, an electric telescopic rod, etc.

[0010] The fixed limiting side plate is fixed to a side of the placement plate away from the horizontal transmission mechanism;

[0011] The movable limiting side plate is mounted on the placement plate via a second lifting mechanism, the movable limiting side plate is opposite to the fixed limiting side plate, and the second lifting mechanism is used to drive the movable limiting side plate to move vertically relative to the placement plate;

[0014] As a further optimized solution of the present invention, the first limiting surface and the second limiting surface gradually approach each other from the feeding end of the horizontal transmission mechanism to the blanking end of the horizontal transmission mechanism, and the first limiting surface and the second limiting surface are higher than the height of the welded pipe on the horizontal transmission mechanism, thereby preventing the welded pipe from slipping out from the side of the horizontal transmission mechanism.

[0015] As a further optimized solution of the present invention, the transmission surface of the horizontal transmission mechanism is tilted, and the transmission surface of the horizontal transmission mechanism gradually tilts upward from the side close to the blanking end to the side away from the blanking end, and also guides the welded pipe.

[0016] As a further optimized solution of the present invention, the movable limiting side plate includes a support plate, a plurality of pressing plates and a plurality of elastic members, the second lifting mechanism is connected to the support plate, one of the pressing plates is mounted on the support plate through a plurality of elastic members, the pressing plate is parallel to the support plate, the elastic member can be elastically deformed along the direction from the pressing plate to the support plate, the plurality of pressing plates are arranged parallel to each other, and the plurality of pressing plates are distributed on the support plate in the vertical direction, thereby facilitating the extrusion of the welded pipes on the same layer;

[0017] Specifically, the elastic member may be a component that can undergo elastic deformation, such as a spring in the prior art.

[0018] As a further optimized solution of the present invention, an elastic belt is provided between any two adjacent pressing plates. The elastic belt can be elastically deformed in the vertical direction. The elastic belt is a columnar or rod-shaped structure made of elastic material.

[0023] In the present invention, the proposed automatic packaging machine for welded pipes drives the placement plate to move vertically and laterally relative to the blanking end of the horizontal transmission mechanism through the first lifting mechanism and the horizontal moving mechanism, so that the welded pipes dropped from the blanking end of the horizontal transmission mechanism are arranged in multiple layers and on the same layer on the placement plate, and the shape formed by the welded pipes is restricted by the movable limiting side plate and the fixed limiting side plate; furthermore, the special structure of the movable limiting side plate facilitates the squeezing of the welded pipes, avoids gaps between two adjacent welded pipes, and increases the packaging effect.

[0034] like Figure 1-4 The automatic baler for welded pipes shown in the figure can pack the welded pipes into a rectangular cross-section structure. The baler includes a horizontal transmission mechanism 1, a frame 2, a placement plate 3, a fixed limit side plate 4, a movable limit side plate 5, a horizontal movement mechanism 6, a first lifting mechanism 7 and a second lifting mechanism 8, wherein:

[0035] In this embodiment, the horizontal transmission mechanism 1 is a belt transmission mechanism in the prior art. The horizontal transmission mechanism 1 is installed on the frame 2. The horizontal transmission mechanism 1 is used to horizontally transmit the welded pipes.

[0036] The transmission surface of the horizontal transmission mechanism 1 is inclined, and the transmission surface of the horizontal transmission mechanism 1 gradually inclines upward from the side close to the blanking end to the side away from the blanking end;

[0037] The frame 2 has a first limiting surface 20 and a second limiting surface 21, which are opposite to each other and form a limiting space, and the horizontal transmission mechanism 1 is located in the limiting space;

[0038] The first limiting surface 20 and the second limiting surface 21 gradually approach each other from the feeding end to the blanking end of the horizontal transmission mechanism 1. The first limiting surface 20 and the second limiting surface 21 are higher than the height of the welded pipe on the horizontal transmission mechanism 1, thereby preventing the welded pipe from slipping out from the side of the horizontal transmission mechanism 1.

[0039] The placing plate 3 is installed on the frame 2, and is used to place the welded pipe, and the placing plate 3 is located below the end of the horizontal transmission mechanism 1;

[0040] In this embodiment, the first lifting mechanism 7 is an electric cylinder, which is installed on the frame 2 and is used to drive the placement plate 3 to move in the vertical direction, thereby facilitating the placement of the welded pipes dropped from the horizontal transmission mechanism 1 on different levels of the placement plate 3;

[0041] In this embodiment, the horizontal moving mechanism 6 is an electric cylinder, which is installed on the frame 2 and is used to drive the placement plate 3 to move horizontally, so that the welded pipes sliding out of the horizontal transmission mechanism 1 can fall on a specific position of the horizontal placement plate 3 so that any two adjacent welded pipes are in close contact; specifically, the horizontal transmission mechanism 1 can be a structure that can drive components to move horizontally, such as an electric cylinder, a screw slider mechanism, or a pneumatic cylinder, an electric telescopic rod, etc. in the prior art;

[0042] Specifically, a mounting plate is installed at the lifting end of the first lifting mechanism 7, and the placement plate 3 is slidably installed on the mounting plate. The placement plate 3 can move toward or away from the discharge end of the horizontal transmission mechanism 1. The horizontal moving mechanism 6 is installed on the mounting plate and is used to drive the placement plate 3 to move horizontally, thereby causing the placement plate 3 to move toward or away from the discharge end of the horizontal transmission mechanism 1.

[0043] The fixed limiting side plate 4 is vertically fixed on the side of the placement plate 3 away from the horizontal transmission mechanism 1;

[0044] The movable limiting side plate 5 is installed on the placement plate 3 through the second lifting mechanism 8. The movable limiting side plate 5 is opposite to the fixed limiting side plate 4. The second lifting mechanism 8 is used to drive the movable limiting side plate 5 to move vertically relative to the placement plate 3.

[0045] Specifically, an extension block 30 is provided below the side of the placement plate 3 close to the horizontal transmission mechanism 1, and a vertical slide groove 300 is opened on the extension block 30. The movable limiting side plate 5 is vertically slidably installed in the slide groove 300. The second lifting mechanism 8 is installed on the placement plate 3 and is used to drive the placement plate 3 to slide out of the slide groove 300 and be located above the placement surface of the placement plate 3 (that is, the upper surface of the placement plate 3 in the figure), and the height of the movable limiting side plate 5 above the placement surface of the placement plate 3 is adjusted according to the number of layers of welded pipes on the placement plate 3;

[0046] Specifically, the second lifting mechanism 8 is an electric cylinder;

[0047] When the plurality of pressing plates 51 are all above the support plate 50, the plurality of pressing plates 51 are in the same plane away from the support plate 50. When the plurality of pressing plates 51 are all above the support plate 50, the plurality of pressing plates 51 are in the same plane away from the support plate 50.

[0048] An elastic band 53 is provided between any two adjacent pressing plates 51. The elastic band 53 can be elastically deformed in the vertical direction. The elastic band 53 is a columnar or rod-shaped structure made of elastic material, which further enhances the positioning effect.

[0049] The height of the pressing plate 51 is equal to the thickness of the welded pipe;

[0050] When the pressing plate 51 is located below the placement plate 3, the elastic member 52 is in a compressed state, that is, the elastic member 52 connected to the pressing plate 51 located in the chute 300 is in a compressed state. When the number of welded pipes in this layer is sufficient, the first lifting mechanism 7 drives the placement plate 3 to move downward, and the second lifting mechanism 8 drives the movable limiting side plate 5 to move upward, thereby facilitating the side limiting of the welded pipes in this layer and squeezing the welded pipes in this layer through the deformation of the elastic member 52.

[0051] A packing groove 31 is formed on the placing plate 3 , and a packing belt is provided in the packing groove 31 , and a height limiting side plate and a movement limiting side plate 5 are extended from both ends of the packing belt.

[0052] During operation, the welded pipes are placed one by one on the horizontal transmission mechanism 1, and the length direction of the welded pipes is perpendicular to the horizontal transmission direction of the horizontal transmission mechanism 1;

[0053] After the first welded pipe is dropped from the horizontal transmission mechanism 1 onto the placement plate 3 and contacts the fixed limiting side plate 4, the horizontal moving mechanism 6 drives the placement plate 3 to move away from the horizontal transmission mechanism 1, thereby placing the second welded pipe on the bottom layer of the placement plate 3 and contacting the first placement plate 3. Similarly, the welded pipes on the same layer are arranged. When the welded pipes on the first layer are distributed, the first lifting mechanism 7 drives the placement plate 3 to move downward, and the second lifting mechanism 8 drives the movable limiting side plate 5 to move upward, thereby facilitating the side limiting of the welded pipes on this layer and squeezing the welded pipes on this layer through the deformation of the elastic member 52. Then, the horizontal moving mechanism 6 drives the placement plate 3 to move closer to the horizontal transmission mechanism 1 so that the first welded pipe placed on the second layer contacts the fixed limiting side plate 4. Then, the above steps are repeated to complete the stacking of multiple layers of welded pipes. The welded pipes are packaged with packaging tape, and after taking out the packaged welded pipes, the pressing plate 51 is squeezed under the action of external force and cooperates with the second lifting mechanism 8 to move downward to move the movable limiting side plate 5 into the slide groove 300.

[0054] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
