Description

Technical Field

[0001] The utility model relates to the technical field of carton palletizing, in particular to a servo carton clamping mechanism. Background Art

[0002] Products such as beverages and food are usually packed in cartons during the packaging process. After packaging, the cartons need to be stacked to facilitate the transportation of the stacked cartons to the warehouse or loading for transportation. When stacking cartons, the cartons need to be clamped to improve the neatness of the stacking. Currently, cylinders are generally used to control the clamps, and the stroke of the cylinder is limited by the clamping sleeve. When the size of the carton changes, in order to adapt to cartons of different sizes, the position of the clamping sleeve needs to be manually adjusted to change the stroke of the cylinder extension, which is very time-consuming and labor-intensive. In addition, when cartons are packed with different products, the speed needs to be adjusted. However, the existing manual adjustment of the cylinder speed control valve has a long downtime, and the cylinder is located at a high position, and the operator needs to climb up to achieve cylinder speed regulation, which poses a safety hazard.

The slide assembly comprises a first slide 31, a second slide 32, and an opening and closing mechanism for driving the first slide 31 and the second slide 32 to merge or separate. The side clamping mechanism comprises a side clamping servo motor assembly 41, a first gear 42 connected to the side clamping servo motor assembly 41, two first racks 43 meshing with the first gear 42, and two side clamping assemblies 44 respectively connected to the two first racks 43. The side clamping servo motor assembly 41 is connected to the carrier frame 1, and the two first racks 43 move in opposite directions. The rear clamping mechanism comprises a rear clamping servo motor assembly 51, a second gear 52 connected to the rear clamping servo motor assembly 51, a second rack 53 meshing with the second gear 52, and a rear clamping plate 54 connected to the second rack 53. The rear clamping servo motor assembly 51 is connected to the carrier frame 1.

[0036] In this embodiment, the conveying mechanism includes a conveying motor 22, two transmission assemblies 23 arranged opposite to each other, and a first main shaft 24 connecting the two transmission assemblies 23. Each transmission assembly 23 includes a first sprocket assembly 231 and a first chain 232 meshing with the first sprocket assembly 231. The push rod 21 is connected to the two first chains 232. The first sprocket assembly 231 of one of the transmission assemblies 23 is connected to the conveying motor 22. The conveying motor 22 drives the first sprocket assembly 231 and the first chain 232 of one of the transmission assemblies 23 to rotate. The first main shaft 24 then drives the first sprocket assembly 231 and the first chain 232 of the other transmission assembly 23 to rotate, ultimately driving the push rod 21 to move.

[0037] To facilitate the merging or separation of the first slide 31 and the second slide 32, the opening and closing mechanism preferably includes an opening and closing motor 33, two opening and closing assemblies 34 arranged opposite to each other, and a second main shaft 35 connecting the two opening and closing assemblies 34. Each opening and closing assembly 34 includes a second sprocket assembly 341 and a second chain 342 meshing with the second sprocket assembly 341. The first slide 31 and the second slide 32 are both connected to the second chain 342 and follow the second chain 342 to make opposite movements. When the second chain 342 drives the first slide 31 and the second slide 32 to move toward each other, the first slide 31 and the second slide 32 merge together; when the first slide 31 and the second slide 32 move away from each other, the first slide 31 and the second slide 32 separate, forming a gap between the first slide 31 and the second slide 32, so that the carton can fall through the gap onto the pallet below.

[0038] See also Figure 5-Figure 7 The side clamping assembly 44 includes a base 441 , a side clamping plate 442 connected to the base 441 , and the first rack 43 is connected to the base 441 .

[0039] Preferably, a slider 443 is provided on the base 441, and the slider 443 is matched with a slide rail 444, and the slide rail 444 is fixed to the carrier 1. The base 441 moves along the slide rail 444 through the slider 443, ensuring the linearity of the movement of the two side clamps 442, thereby improving the stability and reliability of the side clamp.

[0040] Preferably, the base 441 is in an inverted L shape, and a reinforcing rod 445 is connected between the base 441 and the side clamping plate 442. The base 441 is in an inverted L shape, which is convenient for arranging the slider 443 on the base 441 and for connecting with the side clamping plate 442.

[0041] In order to limit the first rack 43 and improve the stability of the movement of the first rack 43 , two cam guides 45 are preferably provided on the side clamp servo motor assembly 41 , and each first rack 43 is located between the first gear 42 and the cam guide 45 .

[0042] See also Figure 8、 Figure 9 The first slide 31 is provided with a slide frame 311 on its periphery. Two adjustment plates 312 are disposed opposite each other on the slide frame 311. The front sections of the two adjustment plates 312 form an inverted figure eight structure. The front sections of the two adjustment plates 312 provide guidance, facilitating the entry of cartons onto the first slide 31. The distance between the two adjustment plates 312 is adjustable, facilitating the positioning of cartons of different sizes.

[0043] The rear end of the carrier 1 is preferably provided with at least one guide mechanism 11, which is provided with a limit ring 12. Specifically, the guide mechanism 11 includes a bearing assembly 111 and an optical axis 112 extending through the bearing assembly 111. The front end of the optical axis 112 is connected to the rear clamping plate 54, the bearing assembly 111 is connected to the carrier 1, and the limit ring 12 is fixed to the rear end of the optical axis 112. The provision of the guide mechanism 11 facilitates the stable movement of the rear clamping plate 54, and the provision of the limit ring 12 prevents the optical axis 112 from driving the rear clamping plate 54 out of the carrier 1.

[0044] When the utility model is in use, multiple cartons 6 are arranged in a full layer through the previous process, and the opening and closing motor 33 is started at the same time, and the second chain 342 is driven by the second sprocket assembly 341, so that the first slide 31 and the second slide 32 are merged together, and a layer of cartons is pushed to the slide assembly, such as Figure 10 As shown, the conveying motor 22 is started, the first sprocket assembly 231 drives the first chain 232, the first chain 232 drives the push rod 21, and the push rod 21 pushes the carton to the specified position on the first slide 31 and the second slide 32. At the same time, the rear clamping servo motor 51 is started to drive the second gear 52, and the second gear 52 drives the second rack 53 to move the rear clamping plate 54 to the specified position, thereby clamping the carton front and back. The side clamping servo motor assembly 41 is started to drive the first gear 42, and the first gear 42 drives the two first racks 43 to move in opposite directions, so that the two side clamping plates 442 can clamp the carton on both sides. The lifting mechanism can be used to drive the carrier 1 to move to the upper position of the stacking pallet, and then the opening and closing motor 33 is started, and the first slide 31 and the second slide 32 at the bottom of the carton are moved to the specified position so that a gap appears between the first slide 31 and the second slide 32, and the carton is separated from the first slide 31 and the second slide 32. The conveying motor 22, the rear clamp servo motor assembly 51 and the side clamp servo motor assembly 41 are started, so that the push rod 21, the rear clamp 54 and the side clamp 442 release the carton and drop it to the specified position of the pallet. The clamping speed can be quickly adjusted by adjusting the output speed of the side clamp servo motor assembly 41 and the rear clamp servo motor assembly 51.
