Description

Technical Field

[0001] The present invention relates to the field of pallets, in particular to the technical field of pallets suitable for robot delivery, and specifically to a packing pallet suitable for robot delivery and loading floating multiple cartons. Background Art

[0002] In order to transfer the cartons from the packing structure to the subsequent pharmaceutical packaging production equipment and cooperate with the work of the robot, the traditional carton packaging and transportation structure cannot be used.

[0003] Conventional medicine box packaging is simply stacking cartons together and tying them with packing tape, which makes it impossible to transport quantitative cartons. If placed in an ordinary turnover box, the cartons will expand naturally and there is no suitable gap around them, resulting in the inability to correspond to the parts with robotic grippers. The cartons are easily damaged during transportation. Therefore, at this stage, most people can only use manual delivery. On the one hand, the degree of mechanization is low and the work efficiency is low. On the other hand, there are safety risks for subsequent sterile production. Summary of the Invention

[0032] The present invention proposes a packing pallet suitable for a robot to transfer and load floating multiple cartons, which is used for loading multiple cartons and facilitates the process of transferring multiple cartons at the same time. The present invention does not limit the types of cartons and robots, but the packing pallet structure is particularly suitable for the needs of floating and expanded stacking transportation of multiple cartons.

[0033] In general, the packing pallet for loading floating multiple cartons by a robot according to the present invention mainly comprises a pallet body 1, a clamping groove 2, a bar-shaped protrusion 3 and a flange 4. Figure 1 , which shows the arrangement relationship of the tray body 1, the clamping groove 2, the strip protrusion 3 and the flange 4.

[0034] In order to achieve the purpose of using a robot to clamp and deliver multiple stacked and automatically expanded cartons, and to solve the problem in the background technology that it is impossible to transport quantitative cartons and manual disassembly and secondary dosing is required, for this purpose, in the technical solution provided in this embodiment, a packing pallet is configured according to the quantitative number of cartons that the robot can clamp and deliver at one time. The pallet body 1 is arranged into a structure with an open top and closed sides and bottom, and a cavity is formed inside to place cartons stacked in sequence.

[0035] The stacked cartons are arranged in a column shape in the tray body 1. Therefore, in order to facilitate the insertion of the robot at both ends, a space for inserting the robot's grippers is preset. On the one hand, the two ends of the tray body 1 in the direction of the cartons being arranged in a column are recessed toward the outer side to form a clamping groove 2. Corresponding to the situation where the robot grips at least two grippers on each side, a pair of clamping grooves 2 are provided on the same side, and the grippers of the robot can be inserted into each gap.

[0036] On the other hand, in order to prevent the robot from damaging the carton during the insertion and removal process, first, a connecting groove 5 protruding toward the inside of the tray body 1 is formed between the pair of clamping grooves 2 located on the same side, and the width of the connecting groove 5 is used to isolate the clamping claws and the carton; secondly, the width of the clamping groove 2 is between 6-10 mm, which is conducive to adapting to different robot sizes; in addition, carton boxes are arranged on the upper surface of the tray body 1, and the height of the clamping groove 2 is not less than half of the height of the carton; furthermore, the angle between the bottom of the connecting groove 5 and the clamping groove 2 and the horizontal plane away from the side of the tray body 1 is an acute angle, and with the inclined setting of the four sides of the tray body 1, the overall length and width of the bottom of the tray body 1 are smaller than the length and width of the top, so that the carton placed in this way has space for expansion, and the bottom is slightly compressed and fit together, while the top is relatively loose. When the clamping claw is inserted downward, the top of the carton can shrink inward, combined with the arrangement of the clamping groove 2, to form sufficient avoidance space.

[0037] In addition, in order to avoid damage to the surface of the paper box during transportation, in this embodiment, on the one hand, the four sides of the pallet body 1 are tilted and the top size is larger than the bottom size, that is, a size larger than the paper box is formed on all sides of the paper box, creating a gap to reduce contact; specifically, in actual operation, the angle A between the bottom of the clamping groove 2 and the horizontal plane away from the side of the pallet body 1 is set between 84° and 87°, which can not only maintain the strength of the four sides of the pallet body 1, but also obtain sufficient gap. According to statistics in actual operation, when the width of the clamping groove 2 is 6mm, the angle A is 87°; when the width of the clamping groove 2 is 7mm, the angle A is 85°; when the width of the clamping groove 2 is 10mm, the angle A is 84°.

[0038] In addition, the flanges 4 at both ends of the connection portion 7 between the pair of tray bodies 1 correspond to the device transfer suction cups.

[0039] Preferably, Figure 5 As shown, considering that the carton may be offset to one side, the maximum length difference between the inner diameter of the standard box and the pallet body 1 is k, the minimum width of the gap where the manipulator is inserted is T, the length of the carton after being flattened is l, the height of the clamping groove 2 is h, the width of the flange 4 is w, and the angle between the clamping groove 2 and the inner wall of the carton is α:

[0040] but:

[0041] Sinα=k / h

[0042] T=k+w-lSinα=k+w-lk / h

[0043] Assume that the minimum clamping width T = 15mm and the difference with the maximum length of the pallet body k = 5mm

[0044] Then: l / h=w-10 / 5

[0045] That is, when w=20, l / h=2 / 1, the height of the tray body should not be less than 1 / 2 of the height of the carton;

[0046] or,

[0047] When l / h=3 / 2, w=17.5, that is, w only needs to be greater than or equal to 17.5 mm.

[0048] On the other hand, the inner side surface of the bottom of the tray body 1 is upwardly protruded to form strip-shaped protrusions 3, and there are at least four of them, two of which are located between the clamping grooves 2 on both sides, and the other two are located between the connecting grooves 5 on one side of the clamping grooves 2. They are arranged perpendicular to the paper box, and the strip-shaped protrusions 3 play a role in lifting the paper box. At the same time, the direct contact between the bottom of the paper box and the upper surface of the tray body 1 is reduced, and the contact area is only the top area of ​​the four strip-shaped protrusions 3; at the same time, in order to make the paper box closer to the inside, the strip-shaped protrusions 3 are arranged between the clamping grooves 2 away from the connecting part 7; in addition, the strip-shaped protrusions 3 also have a reinforcement function, so that the tray can be reused many times, reducing costs.

[0049] like Figure 1 As shown, in order to be able to load multiple rows of stacked paper boxes in the same tray body 1, a pair of tray bodies 1 are arranged in parallel, and the pair of tray bodies 1 are connected by a raised connecting part 7. In order to cooperate with the aforementioned four-sided inclined structure, the top of the connecting part 7 is in a relationship of a third chamfer 9, and the angle B between the connecting parts 7 is an acute angle, between 8-15°.

[0050] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
