[0018] After adopting the above technical solution, the effects of the embodiment of the present invention are:

[0019] Since the automatic cover removing and capping machine includes a roller conveyor, one end of the roller conveyor is provided with a lifting belt conveyor mechanism, and the lifting belt conveyor mechanism is arranged perpendicular to the conveying direction of the roller conveyor; barrel body clamping devices are arranged on both sides of the roller conveyor located upstream of the lifting belt conveyor mechanism, and a barrel cover picking and placing device is arranged on the body of the roller conveyor located above the barrel body clamping device. Based on the above structure, when the automatic cover removing and capping machine is working, the roller conveyor conveys the packaging barrel, and then the barrel body of the packaging barrel is clamped by the barrel body clamping device to ensure the fixity of the barrel body position, so as to ensure the accuracy of subsequent cover removal and capping, and then the barrel cover picking and placing device is used to The barrel cover is picked up, and then the barrel body clamping device returns to its position and the roller conveyor continues to convey the barrel body. When the barrel body reaches the lifting belt conveyor mechanism, the lifting belt conveyor mechanism rises and conveys it. Then, the inner bag containing the material is put into the packaging barrel, and then it is conveyed in the direction of the lifting belt conveyor mechanism. After being conveyed to the roller conveyor, the lifting belt conveyor mechanism descends, and the barrel body containing the material falls onto the roller conveyor. Then the roller conveyor conveys it back and is clamped after reaching the barrel body clamping device. The barrel cover picking and placing device places the picked up barrel cover on the barrel body. Then, the roller conveyor conveys it in the direction of the lifting belt conveyor mechanism again to complete the output work.

[0020] In summary, the automatic capping and dispensing machine can realize mechanized automatic capping and dispensing, and the capping and dispensing are of high precision and strong working continuity, which not only effectively improves the work efficiency but also greatly reduces the labor intensity of the staff.

[0021] Since the barrel body clamping device includes an arc-shaped clamping mechanism, the arc-shaped clamping mechanism includes connecting seats arranged on both sides of the machine body, each connecting seat is provided with a first linear driving element, each first linear driving element drives a slide, the sliding directions of the two slides are opposite, and each slide is provided with a clamping plate located above the roller conveyor, and the sides of the two clamping plates close to each other are provided with arc-shaped positioning grooves. Therefore, when the packaging barrel with an arc-shaped structure is conveyed to the clamping plate position, the two first linear driving elements respectively drive the slide and the clamping plate arranged on the slide to approach the barrel body. During the movement, the barrel body with the arc-shaped structure is clamped by the clamping plate, and the barrel body with the arc-shaped structure is clamped by the arc-shaped positioning groove. The structure is simple and the clamping and positioning effect is good.

[0022] Since a plurality of rollers are rotatably mounted on the clamping plate, the rollers are vertically arranged and disposed on both sides of the arc-shaped positioning groove, the rotating rollers can guide the packaging barrels into and out of the arc-shaped positioning grooves during the conveyance of the packaging barrels with the arc-shaped structures by the roller conveyor, thereby ensuring the smooth movement of the packaging barrels during the precise clamping process; since a rubber protective layer is provided on the rollers, the elasticity of the rubber protective layer itself can play a protective role of elastic buffering, thereby avoiding damage to the packaging barrels caused by hard contact between the rollers and the packaging barrels.

[0023] Since a vertically arranged connecting rod is provided between the clamping plate and the slide seat, the connecting rod is arranged between two adjacent roller shafts; at least two guide rods located below the roller shafts are provided between the two connecting seats, and the two slide seats are slidably installed on the guide rods, so that the structural strength between the two connecting seats is improved through the transition of the connecting rod between the clamping plate and the slide seat, and at the same time, guidance and support are provided for the sliding of the slide seat, and the connection between the slide seat located below the conveying roller and the clamping plate located above the conveying roller is realized through the transition of the guide rod between the two connecting seats; the structure in which the guide rod is located below the conveying roller makes full use of the space below the conveying roller to avoid occupying too much space above the conveying roller and interfering with other components, and at the same time facilitates the arrangement of the third linear drive element and the gear rod.

[0024] Since the barrel body clamping device also includes a square clamping mechanism, the square clamping mechanism includes columns arranged on both sides of the roller conveyor, the columns are provided with a second linear drive element arranged higher than the clamping plate, the second linear drive element is provided with a clamping arm, and the clamping arm is provided with a square positioning groove. Therefore, when the packaging barrel (square) is transported to the position of the square clamping mechanism by the roller conveyor, the two second linear drive elements respectively drive the clamping arms to approach the barrel body and clamp it, and the square barrel body is positioned by the square positioning groove. The structure is simple and the clamping and positioning effect is good.

[0025] Since the clamping arm is arranged directly above the clamping plate, the barrel cover taking and placing device can complete the removal and placement of square barrel covers and arc-shaped barrel covers at the same position without moving, with fewer processes and high precision in the removal and placement of covers.

[0026] Since a mounting seat is provided on the guide rod, vertically arranged third linear drive elements are provided at both ends of the mounting seat, and each third linear drive element drives a plurality of shift rods, which are arranged vertically and set between two adjacent conveying rollers. The shift rods on the two third linear drive elements are distributed at both ends of the clamping plate, so that the packaging barrel is blocked by the shift rods, thereby avoiding the problem that the arc-shaped clamping mechanism or the square clamping mechanism does not clamp the packaging barrel and is transported downstream by the roller conveyor; at the same time, the roller conveyor does not need to perform frequent shutdown operations during the conveying operation.

[0027] The barrel cover picking and placing device includes a support seat arranged on the machine body, and the support seat is provided with a mounting platform driven by a vertical sliding mechanism, and the mounting platform is arranged to be deflected at an angle relative to the conveying direction of the roller conveyor; a vacuum generator and a plurality of suction cups connected to the vacuum generator are provided on the mounting platform, and the suction ends of the suction cups face the roller conveyor; the suction cups are vacuum suction cups with springs, so that after the barrel body clamping device clamps the packaging barrel, the vertical sliding mechanism drives the mounting platform downward and approaches the packaging barrel, and then the vacuum generator works and generates suction, and the suction cup will absorb the barrel cover, otherwise, the barrel cover will be released, the structure is simple, the effect of absorbing and releasing the barrel cover is good, and the action is completed quickly; because the suction cups are vacuum suction cups with springs, when they come into contact with the barrel cover, the springs can make the suction cups perform floating buffering to avoid hard contact and mutual damage.

[0028] Since both ends of the mounting platform are provided with a clamping mechanism, the clamping mechanism includes at least two guide rods arranged on the mounting platform, both ends of the guide rods protrude from the two ends of the mounting platform, and both ends of the guide rods are provided with mounting plates, and the mounting plates are provided with a fourth linear drive element; a slide plate is slidably installed on the guide rod between the mounting plate and the mounting platform, and the slide plate is driven by the fourth linear drive element, and at least two clamping rods extending in the direction of the roller conveyor are provided on the slide plate, and the bottom end of the suction cup is higher than the lower end of the clamping rod, so that after the mounting platform moves downward and approaches the barrel cover, the fourth linear drive elements at both ends of the mounting platform drive the slide plate to move on the guide rod (the two slide plates are close to each other), and in the process of the movement of the two slide plates, the clamping rod will move the packaging barrel to align the packaging barrel with the center of the mounting platform (especially for a square barrel, the two slide plates are distributed at two opposite corners of the square barrel, and the clamping rods are conveniently distributed on the four sides of the square barrel, and then the slide plate completes the alignment work during movement), the structure is simple, the conception is ingenious, the alignment effect is good, and it is conducive to the accurate absorption and release of the barrel cover.

[0029] Since the vertical sliding mechanism includes a fixed seat fixedly mounted on the support seat, a fifth linear drive element connected to the mounting platform is vertically provided on the fixed seat; at least two vertically arranged guide shafts are also slidably mounted on the fixed seat, and one end of the guide shaft is fixedly connected to the mounting platform. Therefore, when the vertical movement of the mounting platform is realized, the fifth linear drive element drives the mounting platform to move, and during the movement, the guide shaft moves linearly on the fixed seat. The structure is simple, and the vertical movement is stable and reliable.

[0030] Since a first limit column for limiting the movement of the slide is provided on the installation platform or the slide, the movement of the slide is limited by the first limit column, thereby preventing the clamping rod from moving too far and causing damage to the barrel cover; since a limit plate is provided at the other end of all guide shafts, a second limit column is provided on the limit plate, and the second limit column is vertically arranged and facing the fixed seat, multiple guide shafts are connected by the limit plate, thereby ensuring the linearity of the movement of the guide shafts, and limiting the movement of the installation platform by the second limit column, thereby preventing the normal barrel cover removal and placement work from being affected by excessive movement.

[0031] Since a protective cover is also provided on the body of the roller conveyor, the lifting belt conveyor mechanism, the barrel clamping device and the barrel cover taking and placing device are all located inside the protective cover, so that the protective cover plays a protective role and ensures safety during the working process; since a protective door is provided on the protective cover and a travel switch is provided on the protective door, the effect of stopping the machine when the protective door is opened is achieved, which further ensures safety in use; since a barrel inlet, a barrel outlet and a feed port are also provided on the protective cover, the barrel inlet and the barrel outlet are distributed in the conveying direction of the roller conveyor and are arranged on both sides of the protective cover, and the feed port is arranged on the protective cover in the conveying direction of the lifting belt conveyor mechanism, so that the entry and output of the packaging barrel and the input of the material all have corresponding independent working ports without interfering with each other.

[0032] The embodiment of the present invention also provides an automatic cover removal and cover placement method to achieve the purpose of mechanized automatic cover removal and cover placement and improve work efficiency.

[0033] An automatic capping and covering method, the automatic capping and covering method using the automatic capping and covering machine described above, comprising the following steps:

[0034] S1. The packaging barrel is transported by a roller conveyor and enters the protective cover through the barrel inlet;

[0035] S2. When the packaging barrel is transported to the vicinity of the barrel clamping device, the stopper located downstream of the barrel clamping device is driven by the third linear drive element to block the packaging barrel, and then the barrel is clamped by the barrel clamping device;

[0036] S3. When the packaging barrel is in an arc-shaped transition shape, an arc-shaped clamping mechanism is used for clamping. Specifically, during the transportation of the packaging barrel, the first linear drive element drives the slide to approach the packaging barrel, and at the same time, the packaging barrel is guided into the arc-shaped positioning groove by the roller, so that the clamping plate clamps the packaging barrel;

[0037] S4. When the packaging barrel is square, a square clamping mechanism is used for clamping. Specifically, during the transportation of the packaging barrel, the second linear drive element drives the clamping arm to approach the packaging barrel and constrain the packaging barrel through the square positioning groove, thereby completing the clamping of the packaging barrel by the clamping arm;

[0038] S5, after the packaging barrel in the above S3 or S4 process is securely clamped, the fifth linear drive element drives the mounting platform to approach the packaging barrel, and at the same time, the vacuum generator works, and the suction cup sucks the barrel cover on the packaging barrel;

[0039] S6. Since the mounting platform is set at an angle relative to the conveying direction of the roller conveyor, before the suction cup absorbs the barrel cover, the fourth linear drive element drives the slide plate to move on the guide rod. At the same time, the clamping rod will move the packaging barrel to realize the alignment of the packaging barrel position and can assist in clamping the packaging barrel after it is absorbed. After that, the absorbed barrel cover is driven up by the mounting platform.

[0040] S7, the barrel clamping device and the lever return to their original positions, and the barrel of the packaging barrel is transported to the position of the lifting belt conveyor mechanism through the roller conveyor;

[0041] S8, the lifting belt conveyor mechanism rises and drives the barrel body to be conveyed toward the feeding port, and then the inner bag containing the material is loaded into the barrel body, and then the lifting belt conveyor mechanism conveys the material in the reverse direction, and after conveying it to the roller conveyor position, the lifting belt conveyor mechanism descends, and the barrel body containing the material falls onto the conveying roller on the roller conveyor;

[0042] S9, the roller conveyor transports in the reverse direction. When transporting to the barrel body clamping device, the stopper located upstream of the barrel body clamping device is driven by the third linear drive element to block the barrel body. Then, the barrel body clamping device clamps the barrel body, the mounting platform falls, and the barrel cover is released onto the barrel body. Then, the barrel body clamping device and the stopper return to their original positions.

[0043] S10, the roller conveyor transports the material in the reverse direction again and outputs the material through the barrel outlet.

[0044] After adopting the above technical scheme, the effect of the embodiment of the present invention is: realizing mechanized automatic lid removal and lid placement, and the lid removal and lid placement are high in precision and strong in working continuity, which not only effectively improves work efficiency but also greatly reduces the labor intensity of staff.

Since the mounting platform 402 is set at an angle relative to the conveying direction of the roller conveyor 1, before the suction cup 404 absorbs the barrel cover, the fourth linear drive element 603 drives the slide plate 604 to move on the guide rod 601. At the same time, the clamping rod 605 will move the packaging barrel to realize the alignment of the packaging barrel position and can assist in clamping the packaging barrel after it is absorbed; then, the absorbed barrel cover is driven up by the mounting platform 402;

[0076] S7, the barrel clamping device 3 and the lever 310 return to their original positions, and the barrel of the packaging barrel is transported to the position of the lifting belt conveyor mechanism 2 through the roller conveyor 1;
