Description

Technical Field

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

[0002] Pipe packaging refers to the process of packaging various pipes and fittings. Pipe packaging has a special packaging machine, called a pipe packaging machine. Pipe packaging machine is a mechanical equipment specially used for pipe product packaging, mainly for pipes of various materials, shapes and sizes, such as galvanized steel pipes commonly used in the construction industry and PVC pipes in the water supply and drainage field. It is widely used in pipe manufacturing companies, covering plumbing equipment, building pipes, industrial pipes and automotive parts and other fields. Whether it is batch packaging of large-scale pipe production factories or customized packaging needs of small pipe processing workshops, pipe packaging machines can play a role.

[0003] Pipe packaging machines are generally systematic and must be used in a certain processing sequence. When it is necessary to bundle the pipes individually or in quantitative quantities, it is inconvenient to bundle them directly. It is also inconvenient to unload the pipes as a whole after bundling. The overall unloading is simply piled up on the platform, and the pipes cannot be distributed and processed.

[0004] In view of the above problems, it can be found that it is difficult to avoid the above problems at the same time when using the existing packaging devices for pipe fittings on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, thus failing to achieve the desired effect.

A number of roller barrels are linearly distributed on the inner side of the first roller machine, and damping rollers are circumferentially distributed and linearly distributed on the outer side of the roller barrels.

[0018] A method for packaging pipe fittings comprises the following steps:

[0019] S1: The pipe is inserted from the guide plate, and the small motor is started. The small motor drives the driving wheel to rotate. The first synchronous belt synchronizes the driving wheel and the driven wheel. The driven wheel is driven by the second synchronous belt to rotate, and then drives the conveying wheel to rotate, and the pipe is moved to the processing body. After the processing is completed, the small cylinder is started, and the small cylinder extends a certain length to drive the moving plate to move, so that the distance between the conveying wheels increases a certain amount, and the pipe falls into the limit plate. Then the drive motor is started, and the drive motor drives the conveyor belt to rotate through the belt shaft to discharge the pipe from the limit plate;

[0020] S2: After the pipe fittings are discharged from the limit plate, they will fall into the discharge container. When a certain number of pipe fittings is reached, the hydraulic pusher is started to drive the pusher plate to move the pipe fittings. When the pipe fittings are in the fixed clamps, the telescopic cylinder is started to drive the fixed clamps to fix the pipe fittings, and the pipe fittings are bundled in the strapping machine. As the pusher plate moves the pipe fittings, the electric threaded rod is started to move the second shell and the semicircular shell to both ends of the pipe fittings until the pipe fittings are completely pushed out of the strapping machine by the pusher plate and the pipe fittings fall above the semicircular shell.

[0021] S3: Start the electric slide rail, which drives the guide rail slide to move the first roller machine to the bottom of the semicircular shell. At this time, the roller squeezes the hook-shaped rack to move upward to drive the first spur gear to rotate. The first spur gear drives the second spur gear to rotate synchronously through the belt group and the circular shaft. When the second spur gear rotates, the semi-toothed ring drives the semicircular shell to rotate synchronously. The pipe loses the support of the semicircular shell, and when the hook-shaped rack rises, its hook end squeezes the pipe to accelerate its separation from the semicircular shell. The pipe falls on the first roller machine along the guide plate, and then the first roller machine is reset. The quantitative unloading unit loses the roller support and resets itself by gravity. According to the demand for pipes, the first roller machine is started to rotate the roller barrel, and the roller barrel makes the pipe contact with the inner wall of the first roller machine. Under the synchronous action of the obstruction of the inner wall of the first roller machine and the rotation of the damping roller, the pipe is pushed by the damping roller to move to one of the second roller machines, and the two second roller machines are started to remove the pipes.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The present invention is provided with a quantitative discharging unit, which can control the processing quantity of the pipe fittings each time, and provides a special conveying part for single processing and discharging, so as to achieve the purpose of quantitatively processing the pipe fittings and quantitatively discharging the pipe fittings from the processing body, so as to avoid the problem of inconvenient control of the feeding quantity due to the opening of the feeding space.

[0024] The present invention is provided with a quantitative unloading unit, which can directly bundle the pipe fittings and unload them after bundling, thereby achieving the purpose of not having to unload according to the processing sequence of the packaging machine, so as to avoid the problem of not being able to unload directly after quantitative discharge.

[0025] The present invention is provided with a multi-directional distribution mechanism, which can provide a conveying platform for unloading, and can provide multi-directional conveying for the pipe fittings after unloading, thereby achieving the purpose of providing pipe fittings for multiple demand stations, thereby avoiding the problem of pipe fittings being directly piled up on the unloading platform after packaging.

[0052] See also Figure 1 and Figure 10-12 The present invention provides a technical solution: a packaging device for pipe fittings. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. A multi-directional distribution mechanism 3 is arranged on the left side of the quantitative unloading unit 22. The multi-directional distribution mechanism 3 is located below the quantitative unloading unit 22. The multi-directional distribution mechanism 3 is used for bidirectional transportation of pipe fittings and provides packaged pipe fittings in different directions.

[0053] As a further limitation of the multi-directional distribution mechanism 3 of the present invention, the multi-directional distribution mechanism 3 includes a first roller machine 301, two sets of guide rail slides 302 are fixedly installed on the bottom surface of the first roller machine 301, and the interior of each set of guide rail slides 302 is slidably connected to an electric slide rail 305. Two second roller machines 303 are placed in contact on both sides of the front and rear of the first roller machine 301, and a guide plate 304 is fixedly installed on the upper surface of the first roller machine 301. The guide plate 304 is rotatably connected to rollers 3041 on both sides. The rollers 3041 are rotatably connected to the guide plates 304. The height of 041 cooperates with the height of the arc surface of the hook-type rack 2213. A plurality of roller cylinders 306 are linearly distributed inside the first roller machine 301, and a plurality of damping rollers 307 are circumferentially distributed outside the roller cylinder 306. A multi-directional distribution mechanism 3 is provided, which can provide a conveying platform for unloading, and can provide multi-directional conveying for the pipe fittings after unloading, so as to achieve the purpose of providing pipe fittings for multiple demand stations, so as to avoid the problem of pipe fittings being directly piled up on the unloading platform after packaging.

[0054] The specific implementation of this embodiment is as follows: after the pipe fitting moves and falls on the two semicircular shells 2217, the above-mentioned actions of the two first shells 2210 are performed again, so that the hook-shaped rack 2213 on the first shell 2210 can contact the roller 3041 along the direction of the electric slide rail 305, and then the electric threaded rod 2208 is stopped and the electric slide rail 305 is started. The electric slide rail 305 drives the guide rail slide plate 302 to move the first roller machine 301 to the bottom of the semicircular shell 2217. In this process, the first roller machine 301 drives the roller 3041 to rotate synchronously through the guide plate 304, and the roller 3041 squeezes the hook-shaped rack 2213 along the arc surface of the hook-shaped rack 2213 to move it upward and drive The first spur gear 2212 rotates synchronously, and the rotation of the first spur gear 2212 drives the driving pulley of the belt set 2211 to rotate synchronously. The driving pulley of the belt set 2211 drives the driven pulley of the belt set 2211 to rotate synchronously through the transmission belt of the belt set 2211, so that the driven pulley of the belt set 2211 drives the second spur gear 2215 to rotate synchronously through the circular shaft. When the second spur gear 2215 rotates, the semi-toothed ring 2216 drives the semicircular shell 2217 to rotate synchronously, so that the pipe fitting gradually loses the support of the semicircular shell 2217, and the hook end of the hook-shaped rack 2213 will squeeze the pipe fitting upward during the rising process, so that the force on the pipe fitting in the left and right directions is unbalanced, further pushing the pipe fitting away from the semicircular shell 2217, and finally the pipe fitting The material falls onto the first roller machine 301 along the guide plate 304, and then the first roller machine 301 is reset. At this time, the hook-shaped rack 2213 moves downward under the influence of gravity and drives the first spur gear 2212 to rotate synchronously. The rotation of the first spur gear 2212 drives the driving pulley of the belt group 2211 to rotate synchronously. The driving pulley of the belt group 2211 drives the driven pulley of the belt group 2211 to rotate synchronously through the transmission belt of the belt group 2211, so that the driven pulley of the belt group 2211 drives the second spur gear 2215 to rotate synchronously through the circular shaft. When the second spur gear 2215 rotates, the semi-toothed ring 2216 drives the semi-circular shell 2217 to rotate synchronously to complete the reset, and the guide slide 302 moves to the leftmost end of the electric slide rail 305 When the first roller machine 301 is moved to the second roller machine 303, the first roller machine 301 is started to rotate the roller barrel 306 according to the demand for the pipe. The roller barrel 306 drives the damping roller 307 to rotate synchronously, and the pipe contacts the inner wall of the first roller machine 301 or the guide plate 304 under the friction of the roller barrel 306. Under the obstruction of the contact between the inner wall of the first roller machine 301 or the guide plate 304, the friction between the pipe and the damping roller 307 changes the movement of the pipe along the rolling direction of the damping roller 307 to the front-back direction. The pipe is pushed along the inner wall by the damping roller 307 to one of the second roller machines 303, and the second roller machine 303 is started to transport the pipe to different directions.

[0055] A method for packaging pipe fittings comprises the following steps:

[0056] S1: The pipe is inserted from the guide plate 2102, and the small motor 2115 is started. The small motor 2115 drives the driving wheel 2119 to rotate. The first synchronous belt 2116 synchronizes the driving wheel 2119 and the driven wheel 2117. The driven wheel 2117 is driven by the second synchronous belt 2111 to rotate, and then drives the conveying wheel 2113 to rotate, and the pipe is moved to the processing body 11. After the processing is completed, the small cylinder 2108 is started, and the small cylinder 2108 extends a certain length to drive the moving plate 2109 to move, so that the distance between the conveying wheels 2113 increases a certain distance, and the pipe falls into the limit plate 2103. Then the drive motor 2106 is started, and the drive motor 2106 drives the conveyor belt 2101 to rotate through the belt shaft 2104, and the pipe is discharged from the limit plate 2103;

[0057] S2: After the pipe fittings are discharged from the limiting plate 2103, they will fall into the discharge container 2201. When a certain number of pipe fittings is reached, the hydraulic pusher 2205 is started to drive the pusher plate 2204 to move the pipe fittings. When the pipe fittings are in the fixed clamping jaws 2203, the telescopic cylinder 2202 is started to drive the fixed clamping jaws 2203 to fix the pipe fittings, and the pipe fittings are bundled in the strapping machine 12. As the pusher plate 2204 moves the pipe fittings, the electric threaded rod 2208 is started to move the second housing 2214 and the semicircular housing 2217 to both ends of the pipe fittings until the pipe fittings are completely pushed out of the strapping machine 12 by the pusher plate 2204 and the pipe fittings fall above the semicircular housing 2217.

[0058] S3: Start the electric slide 305, which drives the guide slide 302 to move the first roller 301 to the bottom of the semicircular shell 2217. At this time, the roller 3041 squeezes the hook-shaped rack 2213 and moves it upward to drive the first spur gear 2212 to rotate. The first spur gear 2212 drives the second spur gear 2215 to rotate synchronously through the belt group 2211 and the circular shaft. When the second spur gear 2215 rotates, the semi-toothed ring 2216 drives the semicircular shell 2217 to rotate synchronously. The pipe fitting loses the support of the semicircular shell 2217, and when the hook-shaped rack 2213 rises, its hook end squeezes the pipe fitting to make it The pipe is quickly separated from the semicircular shell 2217, and falls onto the first roller machine 301 along the guide plate 304. The first roller machine 301 is reset, and the quantitative unloading unit 22 loses the support of the roller 3041 and resets itself by gravity. According to the demand for the pipe, the first roller machine 301 is started to rotate the roller cylinder 306, and the roller cylinder 306 makes the pipe contact with the inner wall of the first roller machine 301. Under the synchronous action of the obstruction of the inner wall of the first roller machine 301 and the rotation of the damping roller 307, the pipe is pushed by the damping roller 307 to move to one of the second roller machines 303, and the two second roller machines 303 are started to remove the pipe.
