Description

Technical Field

[0001] This utility model relates to the field of cardboard packaging technology, specifically to a composite cardboard box wrapping machine. Background Technology

[0002] When transporting fragile items such as glassware and precision electronic products, using a cardboard box within a cardboard box can provide additional cushioning and protection. For example, in the tobacco packaging process in cigarette factories, an inner and outer box nesting method is used to package the tobacco. This involves first unfolding and folding the bottom of the stacked inner boxes, then placing a bottomless outer box over the inner box, putting in the tobacco, and then sealing the tops of the inner and outer boxes. Finally, the inner and outer boxes are tied tightly with strapping. This double-layer cardboard box protection can effectively prevent moisture during transportation and storage, ensuring the quality of the tobacco. However, most existing box nesting is done manually, which reduces efficiency and increases the workload of workers. Based on this, a box nesting machine has emerged in the prior art (see reference 1).

[0003] Reference 1: Chinese patent document with patent publication number CN 103287626 B.

[0004] Reference 1 discloses a case-fitting machine, which uses an outer case suction device or an inner case suction device to adsorb the flipped inner case and insert it into the outer case under the drive of the outer case moving mechanism or the inner case moving mechanism. When inserting the inner case, a flip-out case-fitting guide plate is provided above the open side of the formed outer case. When the case-fitting guide plate extends, it tilts inward and rests on the inner and outer pages of the open side of the outer case, thereby realizing the case-fitting process.

[0005] Reference 1 describes a process where the outer pages of the outer box are unfolded using a guide plate to allow the inner box to enter. This requires drive components to be installed at the joints on the guide plate, increasing the complexity of the structure. Furthermore, due to the bending joints, the outer pages of the outer box are restricted from folding outwards because of the bending angle at the joints of the guide plate. This means that the guide plate cannot adapt to the outer pages of different boxes within a certain range to ensure that it fits the corresponding outer pages and keeps them unfolded. Each unfolding and closing requires the guide plate to perform a relatively complex trajectory movement, which increases the structural running time and reduces the efficiency of the box unfolding process. Utility Model Content

[0006] The purpose of this invention is to solve the problem that existing automated equipment for unfolding the outer pages of cartons for carton packing has a complex structure and is prone to reducing packing efficiency, and to provide a composite carton packing machine.

[0007] To address the shortcomings of the aforementioned technical problems, the present invention employs the following technical solution: a composite carton folding machine, comprising a first folding machine and a second folding machine. Both the first and second folding machines have a transmission assembly at their outlets. Each transmission assembly has a limiting frame for assisting in positioning the carton. A gantry frame is positioned above the two limiting frames. A robotic arm slides along the crossbeam of the gantry frame, and an adsorption assembly is mounted on the robotic arm. A lifting assembly and a guide frame for vertical displacement driven by the lifting assembly are also provided at the limiting frame of the first folding machine. The guide frame is a funnel-shaped frame with its narrow end facing downwards.

[0008] As a further optimization of the composite carton wrapping machine of this utility model: the guide frame is a four-sided conical frame with the narrow end facing down;

[0009] As a further optimization of the composite carton wrapping machine of this utility model: the adsorption component includes a support plate and an adsorption plate disposed on the support plate, a plurality of adsorption disks are provided below the adsorption plate, and the adsorption plate is connected to a negative pressure machine disposed on the support plate.

[0010] As a further optimization of the composite carton box wrapping machine of this utility model: the lifting assembly includes a U-shaped lifting frame, with threaded rods rotatably connected to the two vertical sections of the lifting frame. The two threaded rods are driven by a power source to rotate synchronously. The two threaded rods are threadedly connected to lifting blocks that slide with the lifting frame. The two lifting blocks are fixedly connected to the guide frame through connecting blocks.

[0011] As a further optimization of the composite carton wrapping machine of this utility model: both of the threaded rods are equipped with stepper motors at their bottoms, and the two stepper motors operate at the same amplitude.

[0012] As a further optimization of the composite carton wrapping machine of this utility model: a stepper motor is provided at the bottom of any of the threaded rods, and the other threaded rod is chain-driven with the output shaft of the stepper motor.

[0013] As a further optimization of the composite carton sleeve machine of this utility model: the transmission component is a roller conveyor line.

[0014] As a further optimization of the composite carton sleeve machine of this utility model: the end faces of the two limiting frames are flush to simplify the movement trajectory of the robotic arm.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention uses a guide frame with a narrow, downward-facing, four-sided conical shape, connected to a lifting assembly, to facilitate insertion of the guide frame into the top inlet of a square outer box. The guide frame then presses against the four outer pages of the outer box from its four angled sides, allowing the inner box, which is then adsorbed by the adsorption assembly, to be smoothly fed into the outer box, completing the box-fitting process. During the box-fitting process, the guide frame's movement trajectory is a simple vertical linear motion, which simplifies the steps of unfolding the outer box pages compared to existing box-fitting guide plates, thus improving box-fitting efficiency. Furthermore, the linear movement and shape of the guide frame simplify the structure of unfolding the outer box pages compared to existing box-fitting guide plates, thereby reducing the manufacturing cost of the box-fitting machine.

Second folding box machine. Detailed Implementation

[0019] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0020] like Figure 1As shown, the composite carton folding machine, similar to existing technology, includes a first folding machine 1 for folding into an outer carton and a second folding machine 9 for folding into an inner carton. Both the first folding machine 1 and the second folding machine 9 have a conveying assembly 7 at their outlets. Specifically, the conveying assembly 7 is a motor-driven roller conveyor line used to transport the inner and outer cartons. Both conveying assemblies 7 are equipped with limiting frames 8. After the first folding machine 1 and the second folding machine 9 fold the inner and outer cartons, they are positioned relative to each other by the two conveying assemblies 7 at the two limiting frames 8. A gantry frame 3 is located above the two limiting frames 8 and between the first folding machine 1 and the second folding machine 9. A robotic arm 2 is slidably mounted on the crossbeam of the gantry frame 3. The robotic arm 2 has an adsorption component 4 at its robotic hand. Specifically, the robotic arm 2 can drive the adsorption component 4 horizontally or vertically. The robotic arm 2 can carry the adsorption component 4 and slide it horizontally on the crossbeam of the gantry frame 3. It can also drive the adsorption component 4 to adsorb the inner box on the corresponding limiting frame 8. Then, the inner box can be moved above the outer box. Subsequently, the robotic arm 2 will drive the adsorption component 4 to push the inner box downwards, so that the inner box is sent into the outer box. Then, the adsorption component 4 will release the inner box, so that the inner box is placed into the outer box to complete the boxing. Next, the robotic arm 2 will drive the adsorption component 4 to reset, so as to repeat the above operation to continue the boxing work.

[0021] The adsorption assembly 4 includes a support plate 402 and two adsorption plates 403 disposed on the bottom surface of the support plate 402. The bottom surface of the two adsorption plates 403 is provided with multiple adsorption disks 404 communicating with them. Both adsorption plates 403 are connected to a negative pressure machine 401 disposed on the support plate 402. When adsorbing the inner box, the negative pressure machine 401 operates in the corresponding adsorption plate 403 to generate negative pressure, and then concentrates the negative pressure on the adsorption disk 404, thereby increasing the adsorption force of the adsorption disk 404 on the adsorption item, so that the inner box can be stably adsorbed onto the adsorption disk 404, and the inner box can be sent into the outer box by the displacement of the support plate 402 driven by the robotic arm 2 to complete the boxing work.

[0022] The two limiting frames 8 are parallel and their end faces are flush, so that the robotic arm 2 only needs simple lateral and vertical displacement to drive the adsorption component 4 to move up, down, left and right, and complete the operation of sending the inner box into the outer box. That is, the movement trajectory of the robotic arm 2 is simplified to improve the efficiency of box packing.

[0023] Unlike existing technologies, a lifting assembly 6 is provided at the limiting frame 8 corresponding to the first folding box machine 1. The lifting assembly 6 is connected to a guide frame 5 for vertical displacement. Before the outer box is transferred to the guide frame 5, the guide frame 5 is positioned high by the lifting assembly 6 so that the transfer assembly 7 can transfer the outer box below the guide frame 5. Then, the lifting assembly 6 drives the guide frame 5 to move downward. Subsequently, the guide frame 5 opens the outer flap of the outer box to prevent the outer flap from obstructing the insertion of the inner box. After the inner box is inserted, the lifting assembly 6 drives... The guide frame 5 is displaced upwards and reset, so that the unfolding process of the outer page only requires a simple linear displacement, which will improve the efficiency of unfolding the outer page of the outer box to a certain extent. Specifically, the guide frame 5 is a funnel-shaped frame, preferably a four-sided conical frame with the narrow end facing downwards. When unfolding the outer page of the outer box, the guide frame 5 will not clamp the outer page of the outer box due to the joint angle, thus not hindering the unfolding and folding of the outer page of the outer box. Therefore, it can be used for outer boxes of different sizes within a certain range. Moreover, the structure of the guide frame 5 is simple and the manufacturing cost is low.

[0024] The lifting assembly 6 includes a lifting frame 602 with a vertical end. Specifically, the lifting frame 602 is U-shaped. Each of the two vertical sections of the lifting frame 602 is rotatably connected to a threaded rod 601. Both threaded rods 601 are connected to stepper motors, and the two stepper motors operate at the same amplitude. Alternatively, one threaded rod 601 can be driven by a stepper motor to drive the other threaded rod 601 via a chain drive with the stepper motor's output shaft. Each threaded rod 601 is threadedly connected to a lifting block 603 that slides within the lifting frame 602. Specifically, the lifting block 603 slides within a groove formed in the vertical section of the lifting frame 602, and the cross-section of the lifting block 603 and the groove... All surfaces are T-shaped. The lifting block 603 and the guide frame 5 are fixedly connected by the connecting block 604. Specifically, the guide frame 5 is made of plastic. When the transmission component 7 transmits the outer box, the stepper motor drives the threaded rod 601 to cooperate with the lifting frame 602 to make the lifting block 603 slide vertically. The vertical sliding of the lifting block 603 can cause the connecting block 604 to rise and fall synchronously through the connecting block 604. Then, the guide frame 5 can be raised and reset according to the situation, so that the transmission component 7 can transmit the outer box to the bottom of the guide frame 5. At the same time, the guide frame 5 can be moved down according to the situation, so that the outer page of the outer box can be unfolded for the inner box to be inserted.

It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this utility model.
