Technical Field
[0001] The invention relates to the technical field of product packaging equipment, in particular to a packaging production line and a packaging method for a push-pull cover packaging box. Background Art
[0002] like Figure 1 As shown in FIG. 1 , a push-pull lid packaging box is a commonly used packaging box, which is opened and closed by moving the lid and the box body toward each other. When in use, push the box body ( Figure 1 as shown in a) and the box cover ( Figure 1 The packaging box can be opened by pulling in two directions (as shown in b); when closing, the lid needs to be pushed toward the box body, the box body needs to be pushed toward the lid, or both need to be pushed in opposite directions at the same time. In the closed state, the flange a1 at the opening of the box body a is inserted into the side groove b1 of the box cover b, and the raised buckle on the flange a1 of the box body a is snapped into the snap-in on the side groove b1 of the box cover b. During the packaging process, the flange a1 of the separated box body needs to be aligned with the side groove b1 of the box cover before the packaging box can be closed. In addition, the thickness of the box cover is only 1 to 2 mm ( Figure 1 b in the figure), the side height is about 5 to 6 mm ( Figure 1 Therefore, the effective surface is relatively small during packaging. In addition, since the box cover and the box body are closely matched, the positioning operation must be very precise. Therefore, most of the prior art uses manual packaging. Summary of the invention
[0003] To solve the above problems, the present invention provides a packaging production line for push-pull lid packaging boxes, including a conveyor line arranged on the packaging production line for conveying packaging boxes, a box pushing mechanism for pushing the box body of the packaging box onto the conveyor line, and a lid installing mechanism for fixing the box cover above the conveyor line and pushing the box body into the box cover to complete the packaging when the box body is conveyed to the side and lower part of the box cover.
[0004] On the basis of the above scheme, the cover installation mechanism includes a transverse fixing part for fixing the suction cup, a rotating cylinder for driving the transverse fixing part to rotate so that the suction cup rotates between a cover suction position for sucking up the box cover and an assembly position for assembling the box cover to the box body, and a lifting cylinder for driving the transverse fixing part to move up and down so that the suction cup at the cover suction position sucks the box cover and at the same time the suction cup at the assembly position carries the box cover to be assembled on the moving box body.
[0005] Based on the above scheme, stop backs for positioning the packaging box body are arranged at fixed intervals on the conveyor line, and a positioning part is arranged above the conveyor line for flexibly stopping the packaging box body when the packaging box body passes by so that the packaging box body rests on the stop back and continues to be conveyed forward.
[0006] On the basis of the above solution, a stop belt is provided on the side of the conveyor line for stopping the box body pushed onto the conveyor line by the box pushing mechanism.
[0007] Based on the above solution, the positioning portion includes a flexible stop portion for stopping the box body and a fixing portion for fixing the flexible stop portion; in use, the flexible stop portion extends downwardly from one side of the box body to below the upper horizontal plane of the box body.
[0008] Based on the above solution, the flexible stopping part is a rubber sheet or a brush.
[0009] On the basis of the above scheme, it also includes a cover pushing mechanism for pushing the box cover in the box cover bin to the cover suction position.
[0010] On the basis of the above solution, the cover pushing mechanism includes a push plate for pushing the box cover and a push rod for driving the push plate to perform reciprocating motion.
[0011] On the basis of the above solution, a protrusion is provided on the upper part of the push plate for vibrating the box covers stacked in the box cover bin when the push plate moves.
[0012] The present application also provides a packaging method for a push-pull lid packaging box, comprising the following steps:
[0013] (1) Open the conveyor line, and the box pushing mechanism pushes the packaging box body onto the conveyor line;
[0014] (2) The robot on the assembly line puts the product into the packaging box;
[0015] (3) The lid-loading mechanism fixes the box lid above the conveyor line. The box body containing the product on the conveyor line continuously moves toward the box lid along the conveyor line. When it moves to the lower side of the box lid, the box body pushes into the box lid and the packaging is completed.
[0016] The packaging production line for the push-pull lid packaging box of the present invention, in view of the special-shaped structure of the push-pull lid packaging box, positions the box cover perpendicular to the conveying direction through the stop belt arranged on the conveying line; and realizes the positioning of the box cover in the conveying direction through the cooperation between the stop back and the flexible stop part, so as to prepare for the positioning in advance for product packaging and lid installation. At the same time, the cover pushing mechanism can ensure the accuracy and efficiency of the cover pushing through the setting of the push plate and the raised part, and can effectively prevent the box cover in the box cover bin from falling and getting stuck. The setting of the cover installation mechanism can realize the suction of the box cover for the next cover installation while installing the cover, so as to prepare for the next cover installation.

[0031] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0032] Example 1
[0033] like Figure 2 As shown, the present invention provides a packaging production line for a push-pull lid packaging box, comprising a conveyor line 1 arranged on the packaging production line for conveying packaging boxes; a box pushing mechanism 2 for pushing the box body of the packaging box onto the conveyor line 1;
[0034] A cover-mounting mechanism 3 is used to fix the box cover above the conveyor line 1 and to push the box body into the box cover to complete the packaging when the box body is conveyed to the side and below the box cover.
[0035] Specifically, the conveyor line 1 is constantly moving forward ( Figure 2 The box pushing mechanism 2 continuously pushes the box in the box bin 6 onto the conveyor line 1, and the box moves forward along with the conveyor line 1. After that, the robot puts the product to be packaged into the box. When the product is installed, the box continues to move forward along with the conveyor line 1. When it moves to the lower side of the box cover fixed on the mounting mechanism 3, the flange a1 of the box body is aligned with the side groove b1 of the box cover, and the box continues to move forward along with the conveyor line 1, and the flange a1 is inserted into the side groove b1 of the box cover, and the raised buckle on the flange a1 of the box body a is snapped into the snap-in on the side groove b1 of the box cover b, and the process of installing the cover is completed.
[0036] In the packaging production line of the present application, the positioning of the packaging box body is very critical. In order to fix the position of the box body pushed onto the conveyor line 1, such as Figure 8 As shown, the present application is provided with a stop belt 1-1 on the side of the conveyor line 1 for stopping the box body pushed onto the conveyor line 1 by the box pushing mechanism 2. The setting of the stop belt 1-1 enables the box body pushed onto the conveyor line 1 by the box pushing mechanism 2 to lean against the stop belt 1-1, thereby maintaining a positioning of the box pushing direction.
[0037] Specifically, Fig. 9 As shown, the stop belt 1 - 1 is formed on both sides of the chain plate of the conveyor line 1 , that is, the two sides of the chain plate are high and the middle part is low, and the low part is just placed into the box body.
[0038] In addition to the positioning of the box pushing direction, the positioning of the box body along the conveying line direction is also very critical. For this purpose, the present application provides a specific implementation method, such as Figure 3 and 4As shown, stop backs 1-2 for positioning the packaging box body are arranged at fixed intervals on the conveyor line 1 (specifically, the stop backs 1-2 are arranged on the chain plate of the conveyor line 1), and a positioning part 4 is arranged above the conveyor line 1 for flexibly stopping the packaging box body when the packaging box body passes by so that the packaging box body rests on the stop back 1-2 and continues to be conveyed forward.
[0039] The use of the stopper back 1-2 and the positioning part 4 enables the boxes resting on the stopper belt 1-1 to be conveyed forward at the same position on the conveyor line 1, so as to prepare for positioning for the next step of product boxing and capping.
[0040] As a specific implementation scheme, Figure 3 As shown, the positioning portion 4 includes a flexible stop portion 4-1 for stopping the box body and a fixing portion 4-2 for fixing the flexible stop portion 4-1; in use, the flexible stop portion 4-1 extends downwardly from one side of the box body to below the upper horizontal plane of the box body.
[0041] Specifically, when the box body resting on the stop belt 1-1 hits the flexible stopper 4-1, the flexible stopper 4-1 will prevent the box body from moving forward, thereby keeping the box body stationary relative to the conveyor line 1; when the stopper back 1-2 set on the conveyor line 1 hits the box body, it will give the box body a forward thrust, so that it passes through the stopper of the flexible stopper 4-1. The box body passing through the flexible stopper 4-1 is now completely positioned on the conveyor line 1.
[0042] Specifically, the flexible stopper 4 - 1 may be made of a rubber sheet or a brush.
[0043] like Figure 4 and Figure 5 As shown, the cover installation mechanism 3 includes a transverse fixing part 3-2 with suction cups 3-1 fixed at both ends, a rotating cylinder 3-3 used to drive the transverse fixing part 3-2 to rotate so that the suction cup 3-1 rotates between a cover suction position for sucking up the box cover and an assembly position for assembling the box cover to the box body, and a lifting cylinder 3-4 used to drive the transverse fixing part 3-2 to move up and down so that the suction cup 3-1 at the cover suction position sucks the box cover and at the same time, the suction cup 3-1 at the assembly position is assembled with the box cover to the moving box body.
[0044] Specifically, the cover suction position refers to the position where the box cover is placed before packaging, that is, Figure 4 The position shown in b in the figure, at this position, the suction cup 3-1 will suck up the box cover, and then the lifting cylinder 3-4 will drive it to rise, and then the rotating cylinder 3-3 will rotate 180°, driving it to rotate above the conveyor line 1, that is, the assembly position ( Figure 4 The position shown in a).
[0045] The function of the lifting cylinder 3-4 is to make the suction cup 3-1 at the cover suction position suck the box cover and at the same time make the suction cup 3-1 at the assembly position carry the box cover to be assembled on the moving box body. Figure 4 In the state shown, the lifting cylinder 3-4 drives the transverse fixing part 3-2 to move downward. At this time, the suction cup at the cover suction position (position b) will press down on the surface of the box cover so that the suction cup 3-1 sucks the box cover. At the same time, the suction cup 3-1 at the assembly position presses down so that the front end of the box cover without the side groove is placed on the flange a1 of the box body, so that the side groove b1 of the box cover is naturally aligned with the flange a1 of the box body moving in the direction of the box cover, and the raised buckle on the flange a1 of the box body a is inserted into the bayonet on the side groove b1 of the box cover b, so that the box cover is firmly assembled on the box body. After assembling on the box body, release the suction cup 3-1 at the assembly position, and the box cover and the box body are pushed by the stopper back 1-2 to continue moving forward, completing the action of installing the cover. After that, the lifting cylinder 3-4 drives the transverse fixing part 3-2 to move upward again, lifts the suction cup 3-1, and rotates the rotating cylinder 3-3 180° to enter the next cover installation process.
[0046] Based on the above technical solution, in order to facilitate placing the box cover in the cover suction position, such as Figure 2 and Figure 6 As shown, the packaging production line of the present application further comprises a cover pushing mechanism 5 for pushing the box covers in the box cover bin 7 to the cover sucking position.
[0047] Specifically, Fig.10 , Fig.11 As shown, the cover pushing mechanism 5 includes a push plate 5-1 for pushing the box cover and a push rod 5-2 for driving the push plate 5-1 to do reciprocating motion.
[0048] like Figure 1 As shown, because the side wall thickness of the box cover is very thin, only 1 to 2 mm (the same as the thickness of the box cover), natural stacking usually cannot be arranged neatly. When placing the box cover in the box cover bin 7, manual sorting will greatly reduce production efficiency. Therefore, natural stacking is usually adopted. This method can only make the overall direction of the box cover consistent, but it cannot achieve neat stacking. Therefore, the box cover will overlap with the box cover, which reduces the effective surface of the push plate on the side of the box cover. In order to ensure that only one box cover is pushed at a time. The present application provides a specific implementation scheme of the push plate 5-1. Specifically, the thickness of the push plate 5-1 is less than the overall thickness of the box cover. The overall thickness of the box cover refers to Figure 1 and Fig.13 Specifically, the thickness of the push plate 5-1 is one third to one half of the overall thickness of the box cover.
[0049] At the same time, since the box covers are not of a regular structure, when placed in the box cover bin 7, they are not arranged in a regular up-and-down manner. Therefore, after the push plate 5-1 pushes out a box cover, the stacked box covers above may get stuck in the box cover bin 7, which will result in empty boxes being pushed out the next time. In order to solve this technical problem, based on the above technical solution, as Fig.11 and Fig.12 As shown, the upper part of the push plate 5-1 is provided with a protrusion 5-3 for vibrating the stacked box covers in the box cover bin 7 when the push plate 5-1 moves. The setting of the protrusion 5-3 can generate up and down vibrations on the upper stacked box covers as a whole when the push plate 5-1 pushes the box cover at the bottom, so as to prevent the stacked box covers from being stuck in the box cover bin 7 and unable to fall.
[0050] Example 2
[0051] Based on the packaging production line in Example 1, the present invention provides a packaging method for a push-pull lid packaging box, comprising the following steps:
[0052] (1) The conveyor line 1 is turned on, and the box pushing mechanism 2 pushes the box body of the packaging box onto the conveyor line 1;
[0053] (2) A robot on the assembly line 10 loads the product into a packaging box;
[0054] (3) The lid-loading mechanism 3 fixes the box lid above the conveyor line 1. The box body containing the product on the conveyor line 1 continuously moves toward the box lid along the conveyor line 1. When it moves to the lower side of the box lid, the box body pushes into the box lid and the packaging is completed.
[0055] The robot described in step (2) is no longer shown in the figure. The assembly line 10 is used to convey the products to be packaged. The products are conveyed on the assembly line 10 and are loaded into the packaging box body by the robot.
[0056] As a specific implementation, in step (1), after the box pushing mechanism 2 pushes the packaging box body onto the conveyor line 1, the box body moves forward together with the conveyor line 1, and when the box body hits the lower edge of the flexible stop portion 4-1 of the positioning portion 4, the flexible stop portion 4-1 will prevent the box body from continuing to move forward, thereby keeping the box body stationary relative to the conveyor line 1; when the stop back 1-2 set on the conveyor line 1 hits the box body, it will give the box body a forward thrust, causing it to pass through the stop of the flexible stop portion 4-1; the box body that has passed through the flexible stop portion 4-1 now leans on the conveyor line 1 and continues to move forward.
[0057] Based on the above method, as a preferred embodiment, in step (1), when the box pushing mechanism 2 pushes the box body of the packaging box to the conveyor line 1, the box body is positioned in the box pushing direction by the stop belt 1-1 provided on the side of the conveyor line 1;
[0058] The box body is positioned in two directions, ready for the next step of product boxing and lid installation.
[0059] As a specific implementation, in step (3), the lifting cylinder 3-4 of the cover installation mechanism 3 drives the horizontal fixing part 3-2 to move downward. At this time, the suction cup 3-1 located at the assembly position presses down, so that the side groove of the box cover carried by the suction cup 3-1 is aligned with the flange of the box body moving in the direction of the box cover, so that the box cover can be smoothly assembled on the box body; after the assembly is completed, the suction cup 3-1 at the assembly position is released, and the assembled box cover and box body are pushed by the stopper back 1-2 to continue moving forward. Specifically, while the suction cup 3-1 at the assembly position presses down, the suction cup 3-1 at the cover suction position will press down on the surface of the box cover so that the suction cup 3-1 sucks the box cover.
[0060] When the assembly is completed, the lifting cylinder 3-4 drives the horizontal fixing part 3-2 to move upward, lifts the suction cup 3-1, and the rotating cylinder 3-3 rotates 180°. At this time, the suction cup 3-1 rotated from the assembly position to the cover suction position does not carry the box cover; the suction cup 3-1 rotated from the cover suction position to the assembly position carries the box cover.
[0061] In step (3), when the sensor 8 disposed next to the assembly position detects that the packaging box body is about to move to the assembly position, the control system controls the lifting cylinder 3-4 of the cover installation mechanism 3 to drive the horizontal fixing portion 3-2 to move downward. The sensor and the control system are both conventional technical means of those skilled in the art. In addition, the box pushing timing of the box pushing mechanism 2 and the cover pushing timing of the cover pushing mechanism 5 are all controlled by the control system, and will not be described in detail here.
[0062] Each embodiment in this specification is described in a related manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
