Description

Technical Field

[0001] This utility model relates to the field of packaging bag production technology, specifically to a packaging bag stacking and tail-rubbing device and a clamping and tail-rubbing device. Background Technology

[0002] In the traditional packaging bag production process, after the bags are produced by the bag-making machine, they are manually counted, stacked, sorted, and bundled. This results in high production costs, low production efficiency, and difficulty in guaranteeing the accuracy of counting and the effectiveness of sorting and bundling.

[0003] The applicant of this patent has filed a prior patent application with application number CN201810962109.1. This prior patent sets up a primary transmission mechanism, a stacking and sorting mechanism, a continuous receiving mechanism, a secondary transmission mechanism, a tertiary transmission mechanism, and a bundling mechanism. The continuous receiving mechanism continuously receives and stacks sheet materials into stacks, and the stacking and sorting mechanism tidies up the sheet materials during the stacking process. Then, the secondary and tertiary transmission mechanisms transport the materials to the bundling mechanism for bundling. This achieves fully automatic, continuous, and non-stop stacking, sorting, and packaging bundling, reducing manual operation, improving production efficiency, and lowering production costs.

[0004] The aforementioned prior patent can be used to receive ordinary packaging bags. However, problems may arise when using it to receive certain special packaging bags, such as stand-up pouches and zipper bags. These types of packaging bags are characterized by being thicker at one end and thinner at the other. When receiving a large number of stacked packaging bags, the excessive thickness at one end of the stack becomes a serious issue, making the entire stack of bags very prone to sliding and scattering. In addition, an excessively thick stack at one end of the packaging bags can cause difficulties in packing, such as uneven packing and excessive gaps in the packing.

[0005] For these special packaging bags, the manual stacking and bundling method involves a "tail-trimming" process, where the bags in a stack are twisted and staggered to prevent complete overlap. The resulting stack has a cross-section resembling a fishtail or parallelogram, thus mitigating the problem of excessive thickness at one end. However, automating this tail-trimming process remains an unsolved problem. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a packaging bag stacking and tail-rubbing device and a clamping and tail-rubbing device, which can automatically realize the tail-rubbing treatment of packaging bag stacks.

The left and right limiting side plates are vertically opposite to each other on the material-bearing base plate, forming a material-placing space for placing the packaging bag stacks between them. The pointed cavity is located in front of the material-placing space, and the pointed model is located behind the material-placing space.

[0016] As a preferred technical solution, the opening clamp moving mechanism is a robotic arm.

[0017] As a preferred technical solution, the clamping device, after its opening clamp is closed, becomes the pointed head model of the tail-rubbing device.

[0018] The beneficial effects of this utility model are as follows:

[0019] The tail-rubbing device of this utility model is designed with a pointed cavity and a pointed model that cooperate with each other.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0033] The front, back, left, and right directions described in this utility model are relative. In the following embodiments, the top side of the drawing is considered the left, the bottom side is considered the right, the left side of the drawing is considered the front, and the right side is considered the rear. In practical applications, the front and rear can be interchanged by rotating 180 degrees, and the left and right sides can be interchanged; alternatively, the front and rear can be interchanged with the left and right sides by rotating 90 degrees. All these modifications are within the protection scope of this utility model.

[0034] Example 1

[0035] like Figures 1 to 3 The diagram illustrates a packaging bag stacking and tailing device. The tailing device includes a material-bearing base plate 1, a left limiting side plate 2, a right limiting side plate 3, a pointed cavity 4, a pointed model 5, and a tailing drive mechanism 6. The left limiting side plate 2 and the right limiting side plate 3 are vertically opposite each other on the material-bearing base plate 1, forming a material placement space for placing stacks of packaging bags. The pointed cavity 4 is located in front of the material placement space, and the pointed model 5 is located behind the material placement space. The pointed model 5 faces the pointed cavity 4, and the outline of the pointed model 5 matches the cavity shape of the pointed cavity 4. The tailing drive mechanism 6 is used to drive the pointed model 5 to move back and forth or the pointed cavity 4 to move back and forth.

[0036] The tail-rubbing drive mechanism 6 can be designed to drive the pointed model 5 to move back and forth, or it can be designed to drive the pointed cavity 4 to move back and forth. In this embodiment, the tail-rubbing drive mechanism 6 drives the pointed model 5 to move back and forth. The operation process of the packaging bag stacking tail-rubbing device in this embodiment is as follows: the packaging bag stack 7 is placed in the material placement space (e.g., ...). Figure 2 As shown), the tail-rubbing drive mechanism 6 drives the pointed model 5 to move towards the pointed cavity 4, and the packaging bag stack 7 is then rubbed open with its head and tail misaligned under the combined action of the pointed cavity 4 and the pointed model 5 (as shown). Figure 3 As shown in the figure, this automatically achieves the tail-end processing of the packaging bag stack.

[0037] In this embodiment, the outer contour of the pointed model 5 is <-shaped, and the cavity shape of the pointed cavity 4 is <-shaped. For example... Figure 3 As shown, under the combined action of the <-shaped pointed cavity 4 and the pointed model 5, the cross-section of the stack of packaging bags 7 after the tail is rubbed is similar to the shape of a fish tail.

[0038] The tail-rubbing drive mechanism 6 can be any conventional drive mechanism such as a cylinder, hydraulic cylinder, electric cylinder, gear and rack transmission mechanism, nut and screw mechanism or linear motor. In this embodiment, the tail-rubbing drive mechanism 6 is a linear motor.

[0039] The tail-rubbing device also includes a left limiting telescopic mechanism 8 and a right limiting telescopic mechanism 9. The left limiting telescopic mechanism 8 is used to drive the left limiting side plate 2 to move left and right, and the right limiting telescopic mechanism 9 is used to drive the right limiting side plate 3 to move left and right. The left limiting telescopic mechanism 8 and the right limiting telescopic mechanism 9 drive the left limiting side plate 2 and the right limiting side plate 3 to move left and right, which can adjust the width of the material placement space. On the other hand, according to the actual operation needs, when the packaging bag stack is placed in the material placement space, the left limiting side plate 2 and the right limiting side plate 3 can be moved appropriately to slightly clamp the packaging bag stack (whether the left limiting side plate and the right limiting side plate clamp the packaging bag stack, and the degree of clamping, can be adjusted according to the actual working conditions).

[0040] The left limiting telescopic mechanism 8 and the right limiting telescopic mechanism 9 can be various conventional drive mechanisms such as cylinders, hydraulic cylinders, electric cylinders, gear and rack transmission mechanisms, nut and screw mechanisms or linear motors. In this embodiment, both the left limiting telescopic mechanism 8 and the right limiting telescopic mechanism 9 are cylinders.

[0041] Example 2

[0042] The difference between the packaging bag stacking and tail-rubbing device in this embodiment and that in embodiment 1 is: Figure 4 As shown, the outer contour of the pointed model 5 is ∠-shaped, and the cavity shape of the pointed cavity 4 is ∠-shaped. Figure 5 As shown, under the combined action of the ∠-shaped pointed cavity 4 and the pointed model 5, the cross-section of the stack of packaging bags 7 after the tail is rubbed is similar to a parallelogram.

[0043] Example 3

[0044] like Figures 6 to 10 The diagram shows a packaging bag stacking clamping and tail-rubbing device, which includes a clamping device and a tail-rubbing device.

[0045] The clamping device includes an open clamp 10, an open clamp moving mechanism, and an open clamp rotating mechanism 11. The open clamp 10 is used to clamp a stack of packaging bags, the open clamp moving mechanism is used to drive the open clamp 10 to move, and the open clamp rotating mechanism 11 is used to drive the open clamp 10 to rotate.

[0046] The opening clamp moving mechanism drives the opening clamp 10 to move, so as to automatically place the stack of packaging bags and automatically clamp the stack of packaging bags after tail trimming. The opening clamp moving mechanism includes a front-to-back linear movement drive mechanism and / or a vertical linear movement drive mechanism and / or a horizontal linear movement drive mechanism. Here, "or / and" means that the opening clamp moving mechanism can include one or more of the following: a front-to-back linear movement drive mechanism, a vertical linear movement drive mechanism, and a horizontal linear movement drive mechanism, so as to drive the opening clamp to move one or more of the following: front-to-back, vertical, and horizontal. In this embodiment, the opening clamp moving mechanism includes a front-to-back linear movement drive mechanism and a vertical linear movement drive mechanism, that is, the opening clamp 10 is driven to move vertically and back-to-back by a cylinder 12 and a linear motor 13.

[0047] In this embodiment, the opening clamp rotation mechanism 11 is a rotary cylinder. The opening clamp rotation mechanism 11 drives the opening clamp 10 to rotate so that the horizontally stacked packaging bags are rotated 90° and placed in the material placement space of the tailing device (e.g., Figure 8 (As shown).

[0048] In this embodiment, the opening and closing of the opening clamp 10 is achieved by the finger cylinder 14. A clever aspect of this embodiment is that the opening clamp 10 can be used in two ways: when closed, the opening clamp 10 of the gripping device becomes the pointed tip model 5 of the tail-rubbing device (e.g., Figure 9 As shown in the figure, no additional pointed head model is required. The other structures of the tail-rubbing device in this embodiment are the same as those in Embodiment 1.

[0049] The operation process of the packaging bag stacking clamping and tail-rubbing device in this embodiment is as follows: the opening clamp 10 clamps the packaging bag stack 7 (e.g., ...). Figure 7 (as shown); then the opening clamp 10 rotates, rotating the horizontally stacked packaging bag stack 7 90° and placing it in the material placement space (as shown). Figure 8 (As shown); the open clamp 10 retracts and closes to become a pointed head model 5 (as shown). Figure 9 As shown), it then moves towards the pointed cavity 4, and the stack of packaging bags 7 is displaced and split open at the head and tail under the combined action of the pointed cavity 4 and the pointed model 5 (as shown). Figure 10 As shown in the figure, this automatically achieves the tail-end processing of the packaging bag stack.

[0050] Example 4

[0051] The difference between the packaging bag stacking and clamping device in this embodiment and that in embodiment 3 is that the opening clamping mechanism is a robotic arm. The robotic arm drives the opening clamping mechanism to automatically place the packaging bag stacks and automatically clamp and clamp the stacks after clamping. The robotic arm is existing technology, such as multi-axis humanoid robotic arms manufactured by FANUC, KUKA, ABB, JAKA, and Siasun. Therefore, the specific structure of the robotic arm will not be described in detail.

[0052] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention. The scope of protection of the present invention is defined by the claims.
