Description

Technical Field

[0001] This utility model relates to the field of carton palletizing technology, specifically a carton palletizing machine equipped with a robotic arm. Background Technology

[0002] Cardboard boxes, as packaging containers made of cardboard, play an indispensable role in modern logistics, warehousing, retail, and household life due to their lightweight, recyclability, and low cost. They not only protect the contents from damage but also facilitate brand promotion and information delivery through printing and design. After production and processing, when not used for containing goods, several cardboard boxes are often flattened and stacked together using packing straps. To save space, these stacked boxes are then piled up for storage.

[0003] Cardboard box palletizing is an important but labor-intensive task. Traditional manual palletizing methods are not only inefficient, but the repetitive handling over long periods can easily lead to worker fatigue, increasing the risk of workplace accidents. At the same time, it is difficult to guarantee the accuracy and consistency of manual palletizing, making it difficult to meet the needs of large-scale, high-efficiency production.

DETAILED DESCRIPTION

[0019] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0020] Please refer to Figure 1 and Figure 2 A carton stacking machine provided with a mechanical hand comprises a chassis 10, a support table 20, a horizontal translation mechanism 30, a longitudinal translation mechanism 40, a vertical translation mechanism 50, a fixed disc 60, a supporting plate 70 and a plurality of pneumatic suction cups 80. The support table 20 is supported above the chassis 10, and an inverted "U" shape is formed between the chassis 10 and the support table 20. The horizontal translation mechanism 30 is installed on the support table 20 and is provided with a first movable part driven to move horizontally; the longitudinal translation mechanism 40 is installed on the first movable part and is provided with a second movable part driven to move longitudinally; the vertical translation mechanism 50 is installed on the second movable part and is provided with a third movable part driven to move vertically. The fixed disc 60 is fixed on the third movable part and is fixed with the supporting plate 70 through bolt connection. The plurality of pneumatic suction cups 80 are installed on the supporting plate 70 at intervals, and the pneumatic suction cups 80 are used to adsorb the stacked and bundled cartons so that they can move with the plurality of pneumatic suction cups 80.

[0021] In the present embodiment, the horizontal translation mechanism 30, the longitudinal translation mechanism 40 and the vertical translation mechanism 50 can all adopt a ball screw driving mechanism or a gear and rack driving mechanism. When the ball screw driving mechanism is adopted, a screw seat that can move along the screw shaft and a movable part in each translation mechanism are used; when the gear and rack driving mechanism is adopted, a slider or a moving platform is moved by one or more guide rods, and a gear matched with the rack is installed on the slider or the moving platform. These gears are directly driven by a servo motor or a stepper motor through a reducer. After the motor receives a control signal, it starts to rotate, thereby driving the gear to rotate. The rotary motion of the gear is converted into the linear motion of the slider or the moving platform through the cooperation of the tooth structure between the gear and the rack and the guidance of the guide rod. At this time, the slider or the moving platform constitutes the movable part in each translation mechanism.

[0022] In the present embodiment, the adsorption end of the pneumatic suction cup 80 penetrates downward to below the supporting plate 70, and the plurality of pneumatic suction cups 80 are distributed at equal intervals along the radial direction of the supporting plate 70, so that the plurality of pneumatic suction cups 80 can uniformly disperse the force to adsorb the cartons. The pneumatic suction cup 80 is connected between the hose and the external air pump, so that the pneumatic suction cup 80 can avoid interference when it moves with the supporting plate 70.

[0023] The carton stacking machine provided with the mechanical arm can adjust the position of the supporting plate 70 and the plurality of pneumatic suction cups 80 by driving the horizontal translation mechanism 30, the longitudinal translation mechanism 40 and the vertical translation mechanism 50 when in use, so that the plurality of pneumatic suction cups 80 can adsorb and transfer the stacked and bundled cartons at the edge of the device to the position to be stacked for stacking. The horizontal translation mechanism 30, the longitudinal translation mechanism 40 and the vertical translation mechanism 50 can cooperate to adjust the position in the three-dimensional space, and the plurality of pneumatic suction cups 80 can adsorb the stacked and bundled cartons to move, so that the stacked and bundled cartons can be accurately and smoothly controlled in position and picking and placing operation when stacking.

[0024] Referring to Figure 3 The carton stacking machine provided with the mechanical arm can also be used with the guide rail platform 90 and the flatbed trailer 100. The guide rail platform 90 is arranged below the supporting table 20, and the guide rail platform 90 extends to the front and rear sides of the supporting table 20 along the width direction of the supporting table 20. The flatbed trailer 100 is movably arranged on the guide rail platform 90, and the flatbed trailer 100 can move through the gap between the chassis 10 and the supporting table 20. After the flatbed trailer 100 moves to the corresponding position below the supporting plate 70, the stacked and bundled cartons at the edge of the device can be adsorbed and moved to the flatbed trailer 100, and then a certain number of cartons can be stacked on the flatbed trailer 100 and then moved away along the guide rail platform 90. The flatbed trailer 100 can be moved on the guide rail platform 90 to assist in transfer, so that the device can also be used for transferring the cartons.

[0025] The system of the present application can also include a control system for controlling the operation of each driving facility to automatically operate the carton stacking or transfer. It should be understood that the control system is not particularly limited and can be realized by the control technology in the prior art, which will not be described here.

[0026] In all the above-mentioned schemes, the connection between the two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection or other known connection methods, which will not be described one by one. In the above, whenever it is mentioned that it is fixedly connected, it is preferred to be welded. Although embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, replacements and variations of these embodiments can be made without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
