[0002] Plastic barrels are mostly made of polyethylene, polypropylene, polyester and other plastics through blow molding, injection molding, suction molding and rotational molding. They are mostly used to contain liquids and solid items in the chemical, pesticide, pharmaceutical, food, hardware and electronics, electromechanical and other industries. They are mostly used for the storage and transportation of various liquids and have good properties for special hazardous goods packaging. They are not easy to break, rust-proof, light in weight, and have excellent oil and strong corrosion resistance. They are mostly used for hazardous goods packaging that requires heat preservation, moisture resistance, pressure resistance and corrosion resistance.

[0003] During the production of plastic barrels, the barrel body needs to be sent to the testing position by a conveying device to test its air tightness. However, the conveying device generally transports directly, so it is necessary to manually control the start and stop of the conveying device to ensure that the barrel body is in the transplanting position for easy grasping and transfer to the test and retrieval. At the same time, during the manual control start and stop process, the barrel body will be tilted or offset due to inertia, which makes it impossible to accurately transport it to the transplanting position, thus affecting the test of the plastic barrel.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 A plastic barrel conveying device in this embodiment includes an operating table 1 and a conveyor 2 installed on the operating table 1, a plurality of pallet assemblies 3 are placed on the conveyor 2, three groups of limit assemblies 4 between the conveyors 2 and below the pallet assemblies 3, and an upper top assembly 5 located between the two limit assemblies 4 at the head end are fixed on the top of the operating table 1.

[0021] In the above structure, the barrel body can be supported by the pallet assembly, and the barrel body can be limited and positioned, and then the barrel body can be transported in cooperation with the conveyor. During the transportation process, the cooperation of the three sets of limiting assemblies can make the pallet assembly stay at the designated position and wait during the transportation on the conveyor, thereby improving the accuracy of the transportation process. The pallet assembly in the middle position can be lifted and adsorbed into position through the upper jacking assembly, and the clamping and positioning effect of the pallet assembly on the barrel body can also be released, which is convenient for taking out and putting in the barrel body.

[0022] like Figure 2 and 3 The tray assembly 3 includes a plurality of conveying trays 301 placed on the conveyor 2, a baffle 304 and a clamping portion located outside the baffle 304 are fixed at the center of the conveying tray 301, and a through hole 309 adapted to the upper assembly 5 is opened at the bottom of the conveying tray 301. First, place the barrel body into the enclosure. The sidewall of the enclosure can limit the barrel body to prevent the barrel body from shaking and tipping over, and also prevent the barrel body from shifting in position. Then, under the action of the clamping part, the barrel body can be clamped and fixed, thereby improving the stability of the barrel body during transportation. At the same time, when the conveying disc moves, the limiting component is lifted up. When the conveying disc moves, the ejection end of the limiting component will block the movement of the conveying disc, thus playing a pre-emptive role. The conveying disc is lifted up and adsorbed by the upper ejection component to prevent the conveying disc from shifting in position. At the same time, the other ejection end will pass through the through hole to push the clamping part to loosen the clamping position of the barrel body, thus facilitating the external transfer of the barrel body to the test or the transfer of the tested barrel body to the enclosure for placement.

[0023] Among them, the enclosure 304 is U-shaped, and the clamping part includes a fixed block 303 fixed on the conveying plate 301 and extending to the top of the left side of the enclosure 304. The fixed block 303 is L-shaped, and the protruding side is arc-shaped. A recessed block 310 and an elastic mechanism opposite to the fixed block 303 are fixed on the conveying plate 301. A push block 307 that moves inside the recessed block 310 and is in contact with the right side and the top of the right side of the enclosure 304 is fixed between the two ends of the elastic mechanism. The push block 307 is convex, and both ends of the push block 307 are arc-shaped, and an arc-shaped side groove is provided to be in contact with the outer side of the enclosure 304. The push block 307 is located on the inner side of the recessed block 310 and is equipped with a guide wheel 308 above the through hole 309. By retracting the push block and squeezing the elastic mechanism, the concave block can limit the retraction distance of the push block and also play a certain guiding role. When the barrel body is placed on the conveyor disc and located in the enclosure, the enclosure is U-shaped, and the two protruding arc-shaped edges limit the barrel body, and one side of the fixed block limits the other side of the barrel body. Then the squeezing of the elastic mechanism is released, and under the action of the elastic force, the protruding arc surface of the push block will cooperate with the fixed block to complete the fixation of the barrel body. Under the action of the concave arc surface, it can play a limiting role by sticking to the outer side of the enclosure. The clamping force is too large to cause damage to the outer surface of the barrel body, and at the same time it can also ensure that the guide wheel is located directly above the through hole.

[0024] In addition, the elastic mechanism includes a sleeve block 305 fixed on the conveying disc 301, the sleeve block 305 is located on the right side of the recessed block 310, two spring cylinders 306 are fixed on the inner side of the sleeve block 305, and the ejection ends of the two spring cylinders 306 are fixed to the push block 307. When the push block is subjected to force, it will squeeze the ejection end of the spring cylinder and pressurize the spring inside the spring cylinder, so that the push block retreats to a certain position, which is convenient for being placed in the barrel body. When the push block is not subjected to force, the elastic force of the spring in the spring cylinder restores the push block to eject and complete the clamping of the barrel body.

[0025] like Figure 4 and 5The upper push component 5 includes an upper push cylinder 501 fixed on the surface of the operating table 1 and an upper push cylinder 503 located on the right side of the upper push cylinder 501, a suction cup 502 is fixed to the ejection end of the upper push cylinder 501, and a push plate 504 sliding with one side of the upper push cylinder 503 is fixed to the ejection end of the upper push cylinder 503, the push plate 504 is L-shaped, and an insert block 505 that can pass through the through hole 309 is fixed to the top of the push plate 504, and the top of the insert block 505 is inclined. When the conveyor disc is transferred to the top of the upper lifting assembly through the conveyor, the limiting assembly in the middle will limit the conveyor disc. First, the upper lifting cylinder drives the suction cup to lift up and lift up the conveyor disc at the same time, and adsorb it through the suction cup. When the external transplanting device grabs the barrel body, the upper pushing cylinder drives the insert block to lift up and pass through the through hole through the push plate, and then squeezes the guide wheel through the inclined slope on the insert block, thereby driving the push block to move, making it convenient for the outside to take away the barrel body or put it in for re-clamping and positioning.

[0026] Among them, the limiting component 4 includes three limiting cylinders 401 installed on the operating table 1 and arranged at equal distances, a top block 402 is fixed to the ejection end of the limiting cylinder 401, a stopper wheel 405 is torsionally hinged on the inner side of the top block 402, and a buffer 404 located below the right end of the stopper wheel 405 is fixed to the top of the top block 402, as well as a limiting block 406 located on the right side of the buffer 404. There are three limit assemblies, which play a three-time pre-waiting role for the conveyor disc. First, the limit cylinder in the middle drives the top block to lift up, so that the blocking wheel blocks the conveyor disc and moves, waiting for the barrel test, so that the conveyor disc is accurately moved to the test grabbing position. When there is a conveyor disc in the middle, the limit assembly at the head end lifts up to block the next group in advance. After the middle detection is completed, the limit cylinder retreats to a certain position, and the blocking wheel contacts the conveyor disc to reduce resistance, making the retreat process smooth. Then the limit assembly at the tail end is lifted up to block the conveyor disc after the test, waiting for the staff to remove it for storage. Therefore, pre-waiting, precise positioning and waiting for unloading can be achieved. At the same time, when the conveyor disc contacts the blocking wheel, the blocking wheel will be squeezed. During the squeezing process, the buffer will buffer one end of the blocking wheel. At the same time, under the action of the limit block, the rotation limit position of the blocking wheel can be limited.

[0027] At the same time, an opening is provided on the right side of the top block 402, and a guide column 403 located at the opening is fixed at the top of the limit cylinder 401. The cooperation between the guide column and the opening can play a role in limiting and guiding the top block.

[0028] The working principle of the above embodiment is:

[0029] First, place the tray assembly for the barrel body on the conveyor for transportation. The middle limit cylinder drives the blocking wheel to lift up until the conveying disc squeezes the blocking wheel. The blocking wheel is buffered by the buffer and supported by the limit block to limit the blocking wheel, thereby completing the blocking of the conveying disc. Then the first end limit assembly repeats the above operation to lift up until the next group of conveying discs are blocked and limited to achieve the pre-waiting effect. The upper cylinder drives the suction cup to lift up the conveying disc and fix it at the same time until the external grasping device clamps the barrel body. Then the upper push cylinder drives the insert block to lift up through the through hole through the push plate to squeeze the guide wheel. Because the top of the insert block is inclined, it can push the guide wheel , so that the push block squeezes the spring cylinder and shuttles in the concave block at the same time, so that the push block can be separated from the barrel body and the outer side of the enclosure, so that the barrel body can be taken out to complete the test. When the test is completed, the barrel body is placed in the enclosure, and the upper push cylinder drives the insert block to retreat, and under the elastic force of the spring cylinder, the push block is driven to clamp and fix the barrel body to complete the positioning, thereby improving the stability of the conveying barrel body and preventing the barrel body from tipping over and deviating to affect the conveying and grasping position. Then the limit cylinders in the middle and head parts retreat in turn, and the conveying disc is moved out smoothly under the action of the blocking wheel. Then the tail limit assembly is lifted up to limit the conveying disc after the test again and wait for the external disc to be taken.

[0030] In summary, the stability of the barrel during the transportation process can be effectively improved, while also preventing the barrel from shifting during the transportation process, which can lead to the inability to accurately take the barrel and affect the test, and the barrel can be accurately transported to the designated location for waiting.
