Description

Technical Field

[0001] The utility model relates to the field of food packaging production lines, and particularly relates to a carton supporting device. Background Art

[0002] In a normal automated milk production line, there is a box supply platform for transporting boxes in the production line of boxed milk. The boxes used for milk packaging are all folded and stored on the box supply platform. During production, an industrial robot will disassemble the cartons on the box supply platform one by one and send them into the packaging production line for packaging. Approximately twenty boxes of milk in each batch will be concentrated and sent to the side of the packaging box by a conveyor belt. Then, a six-axis robot will pick up a batch of milk at one time and put it into the packaging carton together. However, during the process of putting the milk into the carton, if the flaps on the upper part of the carton cannot be well opened, it will hinder the smooth loading of the boxed milk, and then cause problems in the subsequent carton sealing. Eventually, the production line will stop, affecting the production efficiency of the entire production line.

[0003] Therefore, the current packaging equipment market is highly competitive, and at the same time, efforts are being made to achieve unmanned production lines to improve the reliability of automatic boxing. Integrating this technology into fully automatic boxing equipment to complete the automation of the production line, replacing the manual boxing mode with equipment, and through unmanned automatic sorting and boxing, a large number of production line workers will be reduced. For realizing the simple function of supporting the box, the existing box supporting devices are too complex and costly. Summary of the Invention

[0024] The functions and effects of the present utility model:

[0025] Based on the above device, the utility model builds a fixing frame for the box-supporting pieces above the position of the open carton. When the carton is sent to the position below the fixing frame for the box-supporting pieces through the conveyor belt for positioning, the fixing frame for the box-supporting pieces moves downward under the telescopic drive of the lifting mechanism, and the box-supporting pieces below the fixing frame for the box-supporting pieces will extend into the carton opening. As the robot picks up a box of milk and puts it into the carton, the box-supporting pieces will expand outwards in all directions, and then open the flaps around the upper part of the carton, turning them outwards, ensuring that the problem of the flaps blocking the milk from being packed into the carton will not occur. When the robot puts the milk into the carton, the robot lifts up to pick up the next batch of milk, and the fixing frame for the box-supporting pieces also lifts up. At the same time, the next carton is also sent, and the above process is repeated. This is a cycle of milk packaging.

[0031] The following further elaborates on the utility model in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the protection scope of the present invention. In actual applications, the improvements and adjustments made by those skilled in the art according to the present invention still fall within the protection scope of the present invention.

[0032] In order to better illustrate the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] As Figure 1 described above, the present invention is a simple passive box-supporting device, including a fixing frame for the box-supporting pieces 1, box-supporting pieces 2, a cylinder support 5, a connecting piece 3, a connecting plate 4, etc.

[0034] The fixing frame for the box-supporting pieces 1, whose size is slightly larger than the opening size of the box body, is placed at the uppermost end. Two box-supporting pieces 2 are connected to the lower part of each of the four side frames of the fixing frame for the box-supporting pieces 1, and there are a total of 8 box-supporting pieces.

[0035] Considering the adaptability of various boxes, the box support frame may have multiple specifications and be replaced by disassembly, or the box support frame may have an adjustable size structure, such as a traditional slide rail / adjusting screw structure, an elastic telescopic structure, etc.

[0036] The end of the box support piece 2 away from the box support piece fixing frame has an inward bending angle, that is, its initial position will be offset inward by a certain angle, and when it moves downward, it will be easier to extend into the interior of the carton fold;

[0037] The box support piece 2 and one end of the box support piece fixing frame also have a folded angle, thereby forming an S-like shape. In this way, when the box support piece fixing frame is lowered, the folded angle here can be used to suppress the opening and closing pages of the box body to make it in an open state.

[0038] Two connecting pieces 3 are welded at both ends of the box support piece fixing frame 1, and the connecting pieces 3 are connected to the connecting plate 4 through threaded fasteners;

[0039] The cylinder bracket 5 is a retractable structure, the upper end of which is connected to the connecting plate 4 through a threaded fastener, and the lower end is connected to the two ends of the conveyor 6 through a threaded fastener.

[0040] In actual operation, the working principle of the present invention is as follows: a box support and box sheet fixing frame 1 is built above the position of the open carton. When the carton is sent to the bottom of the box support and box sheet fixing frame 1 by the conveyor belt, the cylinder bracket 5 is telescoped downward, thereby driving the box support and box sheet fixing frame 1 to move downward, and the box support and box sheet 2 below the box support and box sheet fixing frame 1 will extend into the carton mouth. As the robot clamps a box of milk and puts it into the carton, the box support and box sheet 2 will be unfolded to the outside, thereby opening the folding pages 7 around the top of the carton and turning it outward, thereby ensuring that the milk can be packed smoothly. After the robot puts down the milk, the robot lifts up to clamp the next batch of milk, the cylinder bracket 5 is telescoped upward, and the box support and box sheet fixing frame 1 is also lifted up, and the carton filled with milk is transported to the next station for packaging. At the same time, the next empty carton is also positioned below the box support and box sheet fixing frame 1 through the conveying device. The above is a packing cycle of boxed milk. This technology completes the unmanned automatic packaging production line, thereby improving the reliability of automatic packing of boxed milk.
