Description

Technical Field

[0001] The invention relates to the field of packaging can palletizing, in particular to packaging can palletizing equipment. Background Art

[0002] Packaging cans are a common container used to hold and protect products. They are usually used for packaging of various products such as food, beverages, cosmetics, chemicals, etc. During transportation, the finished packaging cans are generally stacked into pallets. Palletizing is crucial in warehousing and transportation, because reasonable palletizing can improve space utilization, ensure that the cans are not easily damaged during transportation, and facilitate inventory and management for managers.

[0003] Some existing food cans are drum-shaped, but the chuck gripper of the traditional palletizing device is difficult to grasp the drum-shaped packaging cans, and careless grasping will cause the drum-shaped food cans to deform, affecting the appearance quality of the food cans.

[0004] The following problems are difficult to solve in the prior art: 1. The existing palletizer generally clamps the two side edges of a layer of packaging cans through the two side clamping plates of the side clamping mechanical claws at the same time, and firmly clamps the entire layer of items for transportation, which is highly efficient. However, this type of mechanical claw can only grab cylindrical and quadrangular prism-shaped packaging cans, and it is difficult to grab the above-mentioned drum-shaped packaging cans; 2. When stacking packaging cans, it is necessary to lay anti-skid paper on the bottom of each layer of packaging cans. The anti-skid paper can increase the friction between the upper and lower layers of packaging cans to prevent them from sliding during palletizing or transportation. Generally, this process is implemented manually, and when laying the anti-skid paper, it is easy to touch the already stacked packaging cans, causing the stacked packaging cans to collapse. In addition, the anti-skid paper is large in size and inconvenient to lay. At the same time, it is easy to wrinkle and warp, which will affect the stability of palletizing. Summary of the invention

[0034] See also Figure 2-Figure 4 The grabbing part 2 includes an electric slider 21 slidably connected to the No. 1 slide rail 11, the lower end of the electric slider 21 is fixedly connected to the No. 1 cylinder 211, the end of the piston rod of the No. 1 cylinder 211 is fixedly connected to a grabbing mounting frame 22, and a plurality of grabbing columns 23 are evenly arranged below the grabbing mounting frame 22. The grabbing mounting frame 22 and the grabbing columns 23 are fixedly connected, and a transmission rod 231 is rotatably connected to the inner side of the grabbing column 23, and a belt pulley 232 is fixedly connected to the upper end of the transmission rod 231. A transmission belt 233 is wound around the belt pulley 232, and the transmission rods 231 of each grabbing column 23 are connected by a transmission belt The belt 233 is used for transmission, and the upper end of the belt pulley 232 of a transmission rod 231 at the rear side is fixedly connected to a driving gear 234; a power cylinder 12 is fixedly connected to the main frame 1 and located at the rear side of the grabbing part 2, and a connecting rod 121 is fixedly connected to the piston rod of the power cylinder 12, and the left and right ends of the connecting rod 121 are fixedly connected to a toggle rack 122, and the distance between the toggle racks 122 on both sides is the stroke of the electric slider 21 from the grabbing position to the placement position. The grabbing part 2 provided in the present invention can effectively and stably clamp drum-shaped packaging cans, and can clamp a whole layer of packaging cans at one time. It can be understood that the present invention can not only clamp and stack drum-shaped packaging cans, but is also suitable for packaging cans with rotary structures, which increases the scope of application of the present invention.

[0035] See also Figure 4 A clamping frame 235 is vertically slidably connected to the grabbing column 23, an external thread is provided at the middle position of the transmission rod 231, the middle part of the transmission rod 231 passes through the clamping frame 235 and is threadedly connected thereto, and the lower side of the clamping frame 235 is an elastic telescopic structure; an ejection disk 236 is fixedly connected to the transmission rod 231 and located at the lower end of the clamping frame 235, and four slide grooves arranged in an involute shape are provided on the ejection disk 236, and a supporting sheet 237 is slidably connected in the slide groove; when the transmission rod 231 rotates, the clamping frame 235 slides in the up and down directions, and at the same time, the slide groove on the ejection disk 236 pushes the supporting sheet 237 to extend and retract, and the outer end of the supporting sheet 237 is a pointed structure.

[0036] The gripping portion 2 provided in the present invention can effectively and stably clamp packaging cans of various rotating body shapes through the movement of multiple gripping columns 23, and the gripping portion 2 provided in the present invention can clamp a whole layer of packaging cans at one time, which is highly efficient and has strong applicability. The gripping points of the packaging cans by the gripping columns 23 provided in the present invention are the upper and lower ends of the packaging cans, that is, the position of the packaging can is limited by upper pressure and lower support, which increases the clamping stability of the packaging can without causing the problem of deformation of the can wall in the case of thin-walled packaging cans.

[0037] Specifically, after the packaging can is pushed to the clamping position, the No. 1 cylinder 211 can be controlled to extend, and the No. 1 cylinder 211 drives the grabbing mounting frame 22 to move downward, and the grabbing column 23 is inserted into the gap between the packaging cans, and the supporting sheet 237 is close to the upper side of the main frame 1. At this time, the driving gear 234 is meshed with the toggle rack 122 on the left side, and the toggle rack 122 drives the driving gear 234 to rotate by controlling the power cylinder 12 to extend. The driving gear 234 is connected to the transmission through the belt pulley 232. The driving belt 233 drives all the transmission rods 231 to rotate clockwise (top view) at the same linear speed. When the transmission rod 231 rotates, the clamping frame 235 slides downward under the action of the external thread thereon. At the same time, the slide groove on the ejection plate 236 pushes the supporting plate 237 to extend. In this process, the clamping frame 235 provides a downward pressure for the packaging can, and at the same time, the supporting plate 237 lifts the packaging can; then the No. 1 cylinder 211 is controlled to retract to lift the packaging can upward, thereby completing the clamping action of the packaging can.

[0038] It should be noted that, see Figure 3 An avoidance groove 15 is provided on the main frame 1 and below the grabbing column 23. When the grabbing column 23 moves downward to the lower limit position, its lower end can be inserted into the avoidance groove 15, and the supporting sheet 237 can extend out of the avoidance groove 15 to facilitate the supporting sheet 237 to hold the packaging can, and the pointed structure of the supporting sheet 237 is convenient for insertion into the lower side of the packaging can.

[0039] See also Figure 2 and Figure 5The laying part 3 includes a drawing piece 31 fixedly connected to the lower end of the electric slider 21, and a bearing plate 32 is installed on the right end of the main frame 1; the drawing piece 31 includes a connecting block 311 fixedly connected to the lower end of the electric slider 21, and a No. 2 cylinder 312 is fixedly connected to the middle of the connecting block 311, and a clamping frame 313 is fixedly connected to the piston rod of the No. 2 cylinder 312, and a clamping plate 314 is slidably connected in the clamping frame 313. The laying part 3 provided in the present invention can automatically lay the anti-skid paper, and flatten the anti-skid paper before laying it to prevent the wrinkles of the anti-skid paper, and effectively prevent the wrinkles and warping of the anti-skid paper from affecting the stability of the stacking. The bearing plate 32 is used to prevent the anti-skid paper, and one end of the anti-skid paper extends into the square through groove. The anti-skid paper is conveyed manually or mechanized. The drawing piece 31 is used to move with the electric slider 21 and clamp the anti-skid paper.

[0040] See also Figure 5 and Figure 6 The front side of the connecting block 311 is rotatably connected to a No. 1 telescopic rod 315, and the upper end of the No. 1 telescopic rod 315 is slidably connected to a transmission gear 316, and the transmission gear 316 and the No. 1 telescopic rod 315 are connected by a No. 1 spring 317, and the lower end of the No. 1 telescopic rod 315 is fixedly connected to a threaded rod 318, and the threaded rod 318 passes through the clamping frame 313 and is threadedly connected thereto, and the lower end of the threaded rod 318 abuts against the upper end of the clamping plate 314, and the upper side surface of the clamping plate 314 is connected to the upper inner wall of the clamping frame 313 through a return elastic column 319; two tooth plates 13 are fixedly connected on the main frame 1 and located at the front side of the extraction member 31, and a guide plate 14 is hinged on the main frame 1 and located above the tooth plate 13, and the ends of the two guide plates 14 away from the hinge point are respectively placed on the side of the two tooth plates 13 away from each other.

[0041] The laying part 3 provided in the present invention can realize the function of automatically laying anti-skid paper through the extraction part 31, without the need for manual laying of anti-skid paper, thereby effectively avoiding the problem that workers touch the stacked packaging cans when laying anti-skid paper, causing the stacked packaging cans to collapse.

[0042] Specifically, after the gripping portion 2 has clamped the packaging can, the gripping portion 2 moves to the right, and the extraction member 31 also moves to the right with it. At the same time, the No. 2 cylinder 312 extends a suitable length so that the clamping frame 313 is aligned with the left end of the anti-slip paper; as the extraction member 31 moves to the right, the transmission gear 316 first contacts the guide plate 14 on the left, and the guide plate 14 on the left pushes the transmission gear 316 upward, and the No. 1 spring 317 is stretched until the transmission gear 316 is out of contact with the guide plate 14 on the left, and the transmission gear 316 returns to its original position. As the gripping portion 2 continues to move to the right, the transmission gear 316 contacts and meshes with the toothed plate 13 on the right, and the transmission gear 316 starts to rotate driven by the toothed plate 13, and the transmission gear 316 drives the clamping plate 314 to gradually rotate through the No. 1 telescopic rod 315 and the threaded rod 318 The left end of the anti-skid paper is clamped in the step. After the packaging cans are stacked, the gripping part 2 moves back to the original position to the left, and the extraction member 31 also pulls the anti-skid paper to follow it to the left. The transmission gear 316 first contacts the guide plate 14 on the right, and the guide plate 14 on the left pushes the transmission gear 316 upward, and the No. 1 spring 317 is stretched until the transmission gear 316 is out of contact with the guide plate 14 on the right, and the transmission gear 316 returns to its original position. As the gripping part 2 continues to move to the left, the transmission gear 316 contacts and meshes with the tooth plate 13 on the left, and the transmission gear 316 starts to rotate under the drive of the tooth plate 13. The transmission gear 316 drives the clamping plate 314 through the No. 1 telescopic rod 315 and the threaded rod 318 to gradually loosen the left end of the anti-skid paper, and the anti-skid paper falls above the packaging can, thereby completing the laying of the anti-skid paper.

[0043] See also Figure 2 and Figure 7 A flattening piece 34 is fixedly connected to the top of the carrying plate 32. The flattening piece 34 is used to flatten the anti-slip paper. The flattening piece 34 includes a flattening bracket 341 installed on the carrying plate 32, and two reciprocating branch chains 342 connected to the flattening bracket 341 and arranged symmetrically in front and back. A squeezing plate 310 for synchronously pushing the two reciprocating branch chains 342 is installed on the connecting block 311. The flattening piece 34 can flatten the anti-slip paper without setting power, so as to prevent the anti-slip paper from wrinkling and warping, which affects the stability of the stacking of packaging cans.

[0044] Specifically, when the connecting block 311 moves to the right, the squeezing plate 310 can automatically cause the two reciprocating branch chains 342 to move synchronously inward and outward, so that the reciprocating branch chains 342 flatten the anti-skid paper.

[0045] See also Figure 7-Figure 9A reciprocating groove is provided on the flattening bracket 341, and the reciprocating branch chain 342 includes a reciprocating sliding plate 344 slidably connected in the reciprocating groove, and the reciprocating sliding plate 344 is installed on the side wall of the reciprocating groove through a return spring 345, and a flattening frame 346 is installed at the lower end of the reciprocating sliding plate 344, and the lower end of the flattening frame 346 is an open structure, and a flattening plate 347 is vertically slidably connected in the flattening frame 346, and a ball plate 348 is evenly installed on the lower side of the flattening plate 347, and the upper end of the ball plate 348 is an elastic telescopic structure, and the top of the ball plate 348 is connected to the upper side wall of the flattening frame 346 through a spring-pressing piece 349; the opposite sides of the reciprocating sliding plates 344 on the two reciprocating branch chains 342 are provided with contact protrusions 340, and the front and rear sides of the extrusion plate 310 are evenly provided with toggle protrusions matching the contact protrusions 340.

[0046] Specifically, when the connecting block 311 drives the squeezing plate 310 to move to the right, the toggle protrusion on the squeezing plate 310 cooperates with the contact protrusion 340 on the reciprocating sliding plate 344 to drive the two reciprocating sliding plates 344 to move away from each other. At this time, the ball plate 348 in the flattening frame 346 can flatten the anti-slip paper. After the toggle protrusion is separated from the contact protrusion 340, the reciprocating sliding plate 344 returns to its initial position under the action of the return spring 345, thereby completing a flattening of the anti-slip paper. After that, the extraction member 31 can clamp the anti-slip paper. When the grasping portion 2 completes the stacking of the packaging cans and moves downward on the stacking plate 16, the extraction member 31 moves to the left, so that the toggle protrusion on the squeezing plate 310 cooperates with the contact protrusion 340 again, thereby realizing the function of flattening the anti-slip paper for the second time, thereby increasing the flattening effect of the anti-slip paper.

[0047] Continue reading Figure 7-Figure 9 A track support rod 343 is provided on the rear side of the flattening plate 347, and the right side of the track support rod 343 passes through the flattening frame 346, and a track plate 3431 is provided on the right side of the flattening bracket 341 for guiding the track support rod 343. Through the cooperation of the track plate 3431 and the track support rod 343, the ball plate 348 can flatten the anti-skid paper when the two reciprocating sliding plates 344 move away from each other. At the same time, when the two reciprocating sliding plates 344 move relative to each other, the ball plate 348 will not contact the anti-skid paper, thereby preventing the relative movement of the two reciprocating sliding plates 344 from causing wrinkles in the anti-skid paper again.

[0048] It should be noted that one end of the track plate 3431 close to the middle of the flattening bracket 341 is arranged to tilt upward, so that when the track support rod 343 moves outward with the reciprocating sliding plate 344, the flattening plate 347 moves downward with the track support rod 343, and then the ball plate 348 can flatten the anti-slip paper. When the track support rod 343 is separated from the track plate 3431, the track support rod 343 can move to the upper side of the track plate 3431, and then when the reciprocating sliding plate 344 moves inward, the track support rod 343 moves on the upper side of the track plate 3431, so that the ball plate 348 will not contact the anti-slip paper, thereby preventing the anti-slip paper from having secondary wrinkles.

[0049] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention and they are still covered by the protection scope of the present invention.
