Description

TECHNICAL FIELD

[0001] The present application relates to the field of packaging, and in particular to an automatic boxing mechanism. BACKGROUND

[0002] When boxing products, especially square boxes with upper cover fastening, first the upper cover and side cover need to be opened, then the material is loaded, then the side cover is pressed and folded, the upper cover is pressed down, and the tongue on the upper cover is inserted into the gap to fasten the upper cover. Because of the high operation requirement, it is currently completed by manual or automatic boxing mechanism.

[0003] However, the current automatic boxing mechanism generally first completes the opening of the box at the opening box station, and then is horizontally conveyed to the boxing station for boxing. As shown in the prior art automatic boxing mechanism, Figure 1 three stations, an opening box station 100', a boxing station 400' and a covering box station 200'. The box is opened at the opening box station 100', and then is conveyed to the boxing station 400' by the box conveying belt 600'. A horizontal pressing strip 300' is arranged on the side above the box conveying belt 600', which presses the upper cover during the conveying of the box, so that the upper cover is kept open during the conveying of the box. At the same time, the product to be boxed is conveyed to the corresponding position of the boxing station 400' from the product conveying belt 500', and the product to be boxed is loaded into the box by the material grabbing and placing device 900', such as a mechanical hand. After boxing, the box continues to be conveyed to the covering box station 200' by the box conveying belt 600', and the covering of the box is completed.

[0004] However, because the position of the box body cannot be kept upright and the side cover cannot be folded outward during the conveying process, a first correction mechanism 700' is further arranged before the boxing station to correct the position of the box body and the side cover. After the boxing station completes the boxing, the box is horizontally conveyed to the covering box station, and a second correction mechanism 800' is further arranged during the conveying process to correct the shape of the upper cover and the side cover. It can be seen that the current automatic boxing mechanism is not reliable, the mechanism is complex, and the land area is large.

[0005] Moreover, when the opening box, boxing and covering box mechanisms have inconsistent efficiency and need to be matched in speed, it will lead to the disorderly increase of branch mechanisms. As shown in the case of Figure 2 a product diversion mechanism 101' needs to be arranged on the side of the product conveying belt, and then a complete automatic boxing mechanism needs to be added on the side. In this way, the mechanism is numerous, the product output line is complex, the layout of the entire factory is chaotic, the land area is huge, and the disorderly increase of the branch mechanisms will lead to the non-uniform conveying of the conveyed material and the final packaged product, further reducing the efficiency, increasing the land area and operation difficulty.

[0052] Figure 11 Fig. 6 is a schematic view of the packaging line in Example 8. DETAILED DESCRIPTION

[0053] Example 1

[0054] Figure 3 Fig. 1 is a schematic view of the structure of a box suitable for the box-filling mechanism in the examples of the present application. As shown in the figure, the box includes an upper cover 81 and two side covers 82. This kind of box can be applied to the packaging of various products in life, such as daily necessities, food, etc., and also includes the packaging of medical products. Before the material is filled, the upper cover 81 and the two side covers 82 need to be opened upward or outward to ensure that the material is smoothly filled, and at the same time, the two side covers 82 cannot be bent and attached to the two sides of the box body by the material when the material is filled. The upper cover 81 is also provided with a plug 811, which needs to be inserted into the box body when the box is closed. Figure 3 As shown in Fig. 2, the automatic box-filling mechanism in the present example includes a frame 1, which is provided with a box-opening device 100, a box-closing device 200, a lifting platform 6, and a material pushing-out device 400.

[0055] Figure 4 The box-opening device 100 completes the box-opening process, and its location is the box-opening station. The box-filling process and the box-opening process are completed in the same station, and the box-closing device 200 completes the box-closing process, and its location is the box-closing station. The lifting platform 6 can drive the box body to move from the box-opening station to the box-closing station.

[0056] The box-opening station is located on the upper surface of the frame 1, and the box-closing station is located in the middle and lower part of the frame 1, below the box-opening station. The lifting platform 6 can move up and down.

[0057] The box 8 in a flat state that has not been opened can also be arranged on the frame 1. In the present example, the box-opening device adopts a suction cup type box opening, including a rodless cylinder 2 and a suction cup 3. As shown in Fig. 3, when the box is opened, the suction cup 3 is extended through the rodless cylinder 2, sucks one side of the box 8 to open it, and forms a box body with an open upper mouth, which is located on the lifting platform 6.

[0058] Figure 5a Figure 5c

[0059] ​​​​In this embodiment, the automatic cartoning mechanism also includes a box body shape-maintaining device 300, which keeps the top cover of the box open and the side covers of the box body vertically upward or outward. The box body shape-maintaining device includes a top cover stop bar 4 and two side cover stop bars 5. The two side cover stop bars 5 are arranged relatively parallel to each other, with the top cover stop bar 4 positioned perpendicular to the side cover stop bars 5. When the suction cup 3 opens the flat box body, the side covers move directly to the outside of the side cover stop bars 5, ensuring that the two covers open upward or outward during loading. When the top cover opens, it is directly blocked by the top cover stop bars 4, which is sufficient to ensure that the top cover also opens upward or outward during loading.

[0060] After the box is opened, the robot puts the materials to be loaded into the box.

[0061] After loading is completed, the lifting platform 6 can directly move vertically downward, and the box body moves downward with the lifting platform 6. At this time, the side cover bars 5 have no effect, and the side covers can directly break away from the side cover bars 5 and move downward. The upper cover has a certain degree of elasticity, so under the action of the material gravity, it can also easily break away from the upper cover bar 4 and move downward with the lifting platform.

[0062] The frame 1 is provided with a blocking device. The blocking device in this embodiment is a baffle 7 located on both sides of the lifting platform. The blocking device keeps the upper side cover of the box body from bending outward to below the upper plane of the box body.

[0063] The lifting platform cylinder 12 drives the lifting platform 6 to descend to the preset box covering position, and the box covering device completes the closing of the box body.

[0064] In this embodiment, the cover box device includes an upper cover plate 18 , a side cover plate 16 , a spring piece 13 , and the like.

[0065] like Figure 6a As shown in Figure 6e, when closing the box, the spring piece 13 is inserted into the inner side of the box body, and at the same time the upper cover shaping cylinder 15 positions the upper cover of the box body, the side cover plate extension cylinder 17 drives the side cover plate 16 to cover the two side covers, and at the same time retracts the upper cover shaping cylinder 15, and the upper cover plate rotation control cylinder 19 drives the upper cover plate 18 to cover the upper cover, and all cylinders return to their original positions to complete the box closing.

[0066] like Figure 7 As shown, the carton is pushed to the finished product conveyor belt 22 by the push plate telescopic cylinder 21, the push plate telescopic cylinder 21 retracts, and the lifting mechanism rises to the box opening mechanism.

[0067] Example 2

[0068] The main difference between this embodiment and embodiment 1 is that this embodiment does not have a box shape maintaining device. The automatic cartoning mechanism of this embodiment is provided with a forced folding mechanism, which forcibly folds the upper cover and the side cover outwards simultaneously or after the carton opening device completes the box opening, so that they remain in the upward or outward open position.

[0069] Example 3

[0070] There are two main differences between this embodiment and embodiment 1. First, in addition to the box body shape maintaining device, the lifting platform is also provided with an upper cover opening maintaining device.

[0071] The upper cover opening maintaining device in this embodiment is two shorter elastic blocking strips, which extend between the upper cover and the box body opening respectively.

[0072] In this embodiment, after the loading is completed, the lifting platform moves downward, and the upper cover opening maintaining device moves downward together with the lifting platform.

[0073] The second difference between this embodiment and embodiment 1 is that the box-closing device in this embodiment does not require a cover-setting cylinder. Throughout the entire descent process, the cover-opening retaining device maintains the cover's opening. When closing the box, after the side covers are closed, the cover-plate rotating cylinder only needs to push the cover plate from the back, causing the cover to pop open the elastic stop bar and close the box body downward.

[0074] Example 4

[0075] The main difference between this embodiment and embodiment 1 is that blocking devices are provided on both sides of the lifting platform, which prevent the upper side cover of the box body from bending outward to below the upper plane of the box body.

[0076] Example 5

[0077] like Figures 8-10 As shown, the frame 1 of this embodiment is also equipped with an openable and closable platform 20. During the carton opening and loading processes, the platform 20 is opened or moved away by the lifting platform 6. When the lifting platform 6 moves downward, the platform 20 closes or moves to its original position, and the next carton opening and loading process begins. The provision of this platform can also serve as a door, allowing the two processes to overlap and improve production efficiency.

[0078] Example 6

[0079] The main difference between this embodiment and embodiment 1 is that, in embodiment 1, a spring sheet is inserted into the box body when closing the box, and the box body is pulled open to achieve smooth insertion of the upper cover tongue, while this embodiment adopts a cylinder method, in which a cylinder is arranged on the outside of the box body to stretch the outer wall of the box body outward to achieve smooth insertion of the upper cover tongue.

[0080] Example 7

[0081] The main difference between the present embodiment and embodiment 1 is that the spring sheet is inserted into the box body in embodiment 1, and the box body is pulled to realize the smooth insertion of the upper cover insertion tongue, while the present embodiment uses the mode of air cylinder, and the air cylinder is arranged on the inner side of the box body to push the inner side wall of the box body outward to realize the smooth insertion of the upper cover insertion tongue.

[0082] Embodiment 8

[0083] As shown in Figure 11 , it is a packaging production line, when one automatic boxing mechanism as shown in embodiment 1 is not enough to meet the packaging efficiency, multiple automatic boxing mechanisms can be added on both sides of the material conveying mechanism in a neat and simple way. The material to be boxed is conveyed to the automatic boxing mechanism by the product conveying belt 500, and the material is boxed into the box body by the material grabbing and placing device 900.

[0084] Although the present application has been disclosed by the preferred embodiments as above, it is not intended to limit the present application, and any person skilled in the art can make some changes and modifications without departing from the spirit and scope of the present application, therefore the protection scope of the present application shall be subject to the scope required by the claims.
