[0007] The pipeline stacking mechanism comprises:

[0008] A connecting disk, the connecting disk is a circular disk-shaped structure, the top of the connecting disk is rotatably connected to one end of the palletizer through a bearing, the output end of the motor is fixedly connected to the center position of the top of the connecting disk, the bottom of the connecting disk is fixedly connected to an electric controller, and the connecting disk is used to fix the electric controller;

[0009] The semicircular cover is an arc-shaped plate-like structure. The top of the semicircular cover is fixedly connected to the bottom of the electric controller. An open mouth mask is fixedly connected to the right side of the semicircular cover. The open mouth mask is a semi-arc-shaped plate-like structure. The semicircular cover is used to load a PVC drain pipe.

[0010] Preferably, a connecting plate A is fixedly connected to the left side of the semicircular cover, and a connecting plate B is fixedly connected to one end of the connecting plate A, and the connecting plate B is a perfect circular plate-shaped structure.

[0011] Preferably, an elastic card block is fixedly connected to the right side of the connecting plate B, the elastic card block is made of rubber and is elastic, and a pressure sensor is fixedly connected to one side of the connecting plate B.

[0012] Preferably, a groove is provided in the elastic block, and the width of the groove in the elastic block is the same as the wall thickness of the PVC drainage pipe.

[0013] Preferably, the pressure sensor is electrically connected to the motor, and an auxiliary mechanism is provided inside the semicircular cover, and the auxiliary mechanism includes a sliding plate.

[0014] Preferably, the outer wall of the sliding plate is slidably connected to the inner wall of the semicircular cover, and the electric controller is used to drive the sliding plate to slide in the inner wall of the semicircular cover.

[0015] Preferably, a sliding groove is provided on the inner wall of the opening cover, an inclined sliding plate is slidably connected to the inner wall of the sliding groove, a connecting rod is fixedly connected to the outer wall of the inclined sliding plate, and one end of the connecting rod is fixedly connected to the sliding plate.

[0016] Preferably, one side of the inclined sliding plate is fixedly connected to a limiting plate, a rotating wheel and a rotating shaft are rotatably connected in the inner wall of the opening cover, one side of the rotating wheel is fixedly connected to one end of the rotating shaft, the rotating wheel is made of rubber and is elastic, and the rotating wheel deforms when it is pressed against the PVC drain pipe.

[0017] The present invention provides an automatic palletizer for drainage pipe production, which has the following beneficial effects:

[0018] 1. The present invention sets a pipe stacking mechanism. With the automatic identification and rotation of the connection plate, after collecting eight PVC drainage pipes once, the connection plate is moved to an octagonal rack on which the eight PVC drainage pipes are placed by the stacking machine, and the stacking is continuously performed. After the PVC drainage pipes that originally needed to be manually transported from the conveying wheel are regularized into a specified shape, the stacking process is combined and integrated by the stacking machine, thereby saving labor and time and improving work efficiency.

[0019] 2. The present invention sets a pipe stacking mechanism. When the PVC drain pipe is inserted into the semicircular cover and enters the connecting plate B to squeeze the pressure sensor, it will first contact the elastic block, and clamp the pipe wall of the PVC drain pipe through the "concave" shape of the elastic block and the elastic deformation of the semicircular cover. The PVC drain pipe is fastened by five elastic blocks, and then the force of the impact elastic block is transmitted to the pressure sensor, so that the connecting plate starts to rotate rapidly by 45 degrees. When the connecting plate rotates, the electric controller and the semicircular cover are driven to rotate synchronously as a whole, so that the PVC drain pipe inserted into the semicircular cover will not be thrown out due to the centrifugal force, and the PVC drain pipe is kept stable to a certain extent, so as to prevent the problem that the position of the PVC drain pipe in the semicircular cover is different and affects the subsequent placement and stacking;

[0020] 3. The present invention sets a pipe stacking mechanism, and the PVC drain pipes wrapped in the semicircular cover that are not perfectly round will naturally fall from the semicircular cover, so that each PVC drain pipe can be collected and stacked, and the PVC drain pipes with unqualified quality can be screened out, ensuring that each stacked PVC drain pipe maintains a uniform quality standard as much as possible, and the screened PVC drain pipes fall to the ground uniformly, which is convenient for the staff to carry out subsequent processing;

[0021] 4. The present invention sets a pipe stacking mechanism. Once the front end of the PVC drain pipe is deformed, it will turn inward or outward and cannot be properly embedded in the elastic block. The damaged notch at the front end of the PVC drain pipe cannot contact the elastic block, and the clamping force on the PVC drain pipe will be lost. When the connecting plate is quickly rotated by 45 degrees, the semicircular cover will be driven to rotate synchronously, and the PVC drain pipe inside the semicircular cover will be thrown outward with the centrifugal force of the rotation and fall to the ground, so as to complete the screening of the unqualified PVC drain pipes, and avoid the appearance of a large number of unqualified PVC drain pipes in the stacking octagonal rack, resulting in a large workload for subsequent manual quality inspection.

[0022] 5. The present invention provides an auxiliary mechanism, and when the connection plate moves to the placement position, the major arc of the semicircular cover is in the shape of a major arc formed by the sliding plate on the inner wall. Therefore, when the PVC drain pipe in each semicircular cover needs to be placed, the sliding plate is retracted inward by starting the electric controller, and the sliding plate is completely retracted into the semicircular cover. The semicircular cover changes from the major arc formed together with the sliding plate to a minor arc, so that the PVC drain pipe clamped inside the semicircular cover naturally falls off to the shelf where it needs to be placed, and the collection is completed;

[0023] 6. The present invention provides an auxiliary mechanism. When the PVC drain pipe enters the semicircular cover, the contact with the rotating wheel drives the rotating wheel to rotate. The PVC drain pipe itself is also pushed into the semicircular cover by the conveying wheel while rotating. Once it hits the elliptical PVC drain pipe, the PVC drain pipe itself starts to rotate continuously until it becomes a vertical ellipse and enters the semicircular cover, thereby avoiding the problem of the PVC drain pipe being squeezed and stuck with the inner wall of the opening or one side of the semicircular cover when entering the semicircular cover.

[0024] 7. The present invention sets a pipe stacking mechanism, and when the PVC drain pipe rotates and enters the semicircular cover, the particles adhered to the outer wall of the PVC drain pipe can be rotated and thrown off, so as to prevent the PVC drain pipe from being adhered to particles or dirt, resulting in a large number of scratches on the outer wall of the PVC drain pipe during the transmission process, and also avoid the situation where moisture corrodes the PVC drain pipe.

[0040] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: an automatic stacking machine for drain pipe production, comprising a base 1 and a PVC drain pipe 6, a stacking machine 2 is fixedly connected to the top of the base 1, a motor 7 is fixedly connected to one end of the stacking machine 2, a control machine 5 is fixedly connected to the outer wall of the stacking machine 2, and a pipe stacking mechanism 3 is arranged at the bottom of the motor 7;

[0041] The pipe stacking mechanism 3 comprises:

[0042] The connecting disk 301 is a circular disk-shaped structure. The top of the connecting disk 301 is rotatably connected to one end of the palletizer 2 through a bearing. The output end of the motor 7 is fixedly connected to the center position of the top of the connecting disk 301. The bottom of the connecting disk 301 is fixedly connected to the electric controller 302. The connecting disk 301 is used to fix the electric controller 302.

[0043] The semicircular cover 303 is a semicircular plate-shaped structure. The top of the semicircular cover 303 is fixedly connected to the bottom of the electric controller 302. The right side of the semicircular cover 303 is fixedly connected with an open mask 304. The open mask 304 is a semi-arc plate-shaped structure. The semicircular cover 303 is used to load the PVC drain pipe 6.

[0044] When in use, the conveying wheel in the factory conveys the PVC drain pipes 6 to the designated location one by one, and then the PVC drain pipes 6 start to detach from the conveying wheel as they are conveyed, so that they fall off the conveying wheel one by one and fall to the ground. When the conveying wheel detaches the PVC drain pipes 6 and they fall to the ground, the PVC drain pipes 6 are kept in the center of the conveying wheel and thus continue to fall to the same location. At this time, when one end of the PVC drain pipe 6 just extends out of the conveying wheel, the control machine 5 is started in advance to control the palletizer 2 to drive the connecting plate 301 and the opening mask 304 to align with the PVC drain pipe 6. The drain pipe 6 comes out of the position, so that the PVC drain pipe 6 that originally fell through the conveying wheel will be directly inserted into the semicircular cover 303 through the opening cover 304 at one end. The semicircular cover 303 is an arc-shaped plate structure. Because the semicircular cover 303 is an excellent arc greater than 180 degrees, the semicircular cover 303 will wrap the PVC drain pipe 6 inserted therein, and the PVC drain pipe 6 will not fall off from the semicircular cover 303. As the conveying wheel continues to push the PVC drain pipe 6, the PVC drain pipe 6 is completely pushed into the connecting plate A306 and the connecting plate B306 on the left side of the semicircular cover 303. 7, and presses against the pressure sensor 308, and the pressure sensor 308 senses the pressure of the collision and sends a signal to the motor 7, so that the motor 7 controls the connection disk 301 to rotate quickly forty-five degrees, automatically aligning the adjacent open mask 304 and the semicircular cover 303 with the PVC drain pipe 6, so that the next PVC drain pipe 6 is pushed vertically by the transmission wheel to the semicircular cover 303 to the pressure sensor 308 at the connection plate B307, and hits the next pressure sensor 308 again, and sends a signal to the motor 7 again, controlling the connection disk 301 to rotate forty-five degrees again. The PVC drainage pipe 6 can be directly collected on the palletizer 2 after passing through the conveying wheel, and with the automatic identification and rotation of the connection plate 301, after the eight PVC drainage pipes 6 are fully collected, the connection plate 301 is moved to the octagonal rack on which the eight PVC drainage pipes 6 are placed by the palletizer 2, and the stacking is continuously performed. After the PVC drainage pipe 6 that originally needed to be manually transported from the conveying wheel is regularized into a specified shape, the stacking process is combined and integrated by the palletizer 2, which saves labor and time and improves work efficiency.

[0045] Example 2: Please refer to Figure 1-11On the basis of the first embodiment, the present invention provides a technical solution: a connecting plate A306 is fixedly connected to the left side of the semicircular cover 303, and a connecting plate B307 is fixedly connected to one end of the connecting plate A306, and the connecting plate B307 is a perfect circular plate structure.

[0046] An elastic block 309 is fixedly connected to the right side of the connecting plate B307. The elastic block 309 is made of rubber and has elasticity. A pressure sensor 308 is fixedly connected to one side of the connecting plate B307.

[0047] A groove is formed in the elastic block 309 , and the width of the groove in the elastic block 309 is the same as the wall thickness of the PVC drainage pipe 6 .

[0048] After the PVC drain pipe 6 is inserted into the semicircular cover 303 and enters the connecting plate B307 to squeeze the pressure sensor 308, it will first contact the elastic block 309, and through the "concave" shape of the elastic block 309 and the elastic deformation of the semicircular cover 303, the pipe wall of the PVC drain pipe 6 is clamped, and the PVC drain pipe 6 is fastened by the five elastic blocks 309. Then, the force of the impact elastic block 309 will be transmitted to the pressure sensor 308, so that the connecting disk 301 starts to rotate rapidly forty-five degrees. When the connecting disk 301 rotates, the electric controller 302 and the semicircular cover 303 are driven to rotate synchronously as a whole, so that the PVC drain pipe 6 inserted into the semicircular cover 303 will not be thrown out due to the centrifugal force, and the PVC drain pipe 6 is kept stable to a certain extent, so as to prevent the problem that the position of the PVC drain pipe 6 in the semicircular cover 303 is different and affects the subsequent placement and stacking;

[0049] Once the PVC drain pipe 6 is deformed due to improper production extrusion control or transportation squeezing, the perfect circle of the cross-section of the PVC drain pipe 6 will become an ellipse. Once it becomes an ellipse, when the PVC drain pipe 6 passes through the arc-shaped semicircular cover 303, the smaller and smaller opening of the opening mask 304 will make the wider position of the elliptical PVC drain pipe 6 unable to enter the semicircular cover 303, and it will rotate itself to a vertical ellipse, so that it can enter the semicircular cover 303. Because the caliber of the inner wall of the semicircular cover 303 is close to the outer diameter of the PVC drain pipe 6 but slightly larger, if the outer shape of the PVC drain pipe 6 is flattened to a certain degree of ellipse, the wider position will be larger than the inner wall of the semicircular cover 303, and it will not be able to enter the semicircular cover 303. Therefore, when passing through the opening mask 304 from large to small, the elliptical PVC drain pipe 6 will be squeezed into a vertical shape, and the PVC drain pipe 6 After entering the semicircular cover 303, the top of the PVC drain pipe 6 is against the upper part of the inner wall of the semicircular cover 303 because the PVC drain pipe 6 becomes a vertical ellipse. As the subsequent conveying wheel continues to push the PVC drain pipe 6, after the half position of the PVC drain pipe 6 is separated from the conveying wheel, it falls from the semicircular cover 303 because of the vertical ellipse. Although the semicircular cover 303 is a superior arc, the length exceeding the semicircle is short. Therefore, once the PVC drain pipe 6 wrapped in the semicircular cover 303 is not a perfect circle, it will naturally fall from the semicircular cover 303. While collecting and stacking each PVC drain pipe 6, the PVC drain pipe 6 of unqualified quality is screened out, ensuring that each of the stacked PVC drain pipes 6 maintains a uniform quality standard as much as possible, and the screened PVC drain pipes 6 fall to the ground uniformly, which is convenient for the staff to carry out subsequent processing.

[0050] When the PVC drain pipe 6 is transported forward on the rotating wheel, it is easy to touch other objects during the forward transmission and transportation, resulting in damage and deformation of the edge of the front end of the PVC drain pipe 6. Once the front end of the PVC drain pipe 6 is deformed, the front end of the PVC drain pipe 6 will be turned inward or outward and cannot be properly embedded in the elastic elastic block 309. The damaged notch at the front end of the PVC drain pipe 6 cannot contact the elastic block 309, and the clamping force on the PVC drain pipe 6 will be lost. When the connecting disk 301 is subsequently rotated forty-five degrees quickly, the semicircular cover 303 will be driven to rotate synchronously, and the PVC drain pipe 6 inside the semicircular cover 303 will be thrown outward with the centrifugal force of the rotation and fall to the ground, completing the screening of the unqualified PVC drain pipes 6, avoiding the appearance of a large number of unqualified PVC drain pipes 6 in the stacking octagonal rack, resulting in a heavy workload for subsequent manual quality inspection.

[0051] Example 3: Please refer to Figure 1-14On the basis of the first and second embodiments, the present invention provides a technical solution: the pressure sensor 308 is electrically connected to the motor 7 , an auxiliary mechanism 4 is provided inside the semicircular cover 303 , and the auxiliary mechanism 4 includes a sliding plate 401 .

[0052] The outer wall of the sliding plate 401 is slidably connected to the inner wall of the semicircular cover 303 , and the electric controller 302 is used to drive the sliding plate 401 to slide in the inner wall of the semicircular cover 303 .

[0053] A sliding groove 305 is provided on the inner wall of the opening cover 304 , and an inclined slide plate 404 is slidably connected to the inner wall of the sliding groove 305 . A connecting rod 402 is fixedly connected to the outer wall of the inclined slide plate 404 , and one end of the connecting rod 402 is fixedly connected to the sliding plate 401 .

[0054] One side of the inclined slide plate 404 is fixedly connected to the limiting plate 403, and a rotating wheel 405 and a rotating shaft 406 are rotatably connected in the inner wall of the opening cover 304. One side of the rotating wheel 405 is fixedly connected to one end of the rotating shaft 406. The rotating wheel 405 is made of rubber and is elastic. The rotating wheel 405 deforms when it is pressed against the PVC drain pipe 6.

[0055] When the connection plate 301 moves to the placement position, the major arc of the semicircular cover 303 is a major arc shape formed by the sliding plate 401 on the inner wall. Therefore, when the PVC drainage pipe 6 in each semicircular cover 303 needs to be placed, the sliding plate 401 is controlled to be retracted inward by starting the electric controller 302. The sliding plate 401 is completely retracted into the semicircular cover 303, and the semicircular cover 303 changes from the major arc formed together with the sliding plate 401 to the minor arc, so that the PVC drainage pipe 6 clamped inside the semicircular cover 303 naturally falls off to the shelf where it needs to be placed, and the collection is completed;

[0056] When the sliding plate 401 is retracted, the inclined sliding plate 404 will be synchronously driven to slide into the opening cover 304 through the connecting rod 402. When the PVC drain pipe 6 enters the opening cover 304, the PVC drain pipe 6 will contact the rotating wheel 405 in the opening cover 304 and push the rotating wheel 405 to roll. Since the rotating wheel 405 is inclined, when pushing the rotating wheel 405 to roll, the inclined rotating wheel 405 will reversely push the PVC drain pipe 6 to rotate through friction, so that the PVC drain pipe 6 When the water pipe 6 enters the semicircular cover 303, the contact with the rotating wheel 405 drives the rotating wheel 405 to rotate, and the PVC drainage pipe 6 itself is also pushed into the semicircular cover 303 by the conveying wheel while rotating. Once the elliptical PVC drainage pipe 6 is encountered, the PVC drainage pipe 6 itself starts to rotate continuously until it becomes a vertical ellipse and enters the semicircular cover 303, thereby preventing the PVC drainage pipe 6 from being squeezed and stuck with the inner wall of the opening cover 304 or one side of the semicircular cover 303 when entering the semicircular cover 303.

[0057] Furthermore, when the PVC drain pipe 6 rotates and enters the semicircular cover 303, the particles adhered to the outer wall of the PVC drain pipe 6 can be rotated and thrown off, thereby preventing the PVC drain pipe 6 from being adhered to particles or dirt, which may cause a large number of scratches on the outer wall of the PVC drain pipe 6 during the transmission process, and also avoiding the situation where moisture corrodes the PVC drain pipe 6.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
