Description

Technical Field

[0001] This utility model relates to the field of tobacco packaging technology, and in particular to a pull belt direction control device and an automatic packaging equipment. Background Technology

[0002] In the tobacco industry's packaging processes, pull-tab packaging technology is a crucial component. As a convenient opening mechanism, pull-tabs are widely used in the packaging of various tobacco products, such as cigarette cartons and packs. They not only provide excellent sealing, protecting tobacco products from external environmental factors, but also offer consumers a convenient opening method, enhancing the product's user experience. Traditional pull-tab packaging technology has achieved relatively mature applications in standard-shaped packaging, enabling efficient and stable automated packaging production.

[0003] However, with the increasing demand from consumers for personalized tobacco product appearance and packaging, irregularly shaped packaging is becoming more and more widely used in the tobacco industry. The shape and structure of irregularly shaped packaging differ significantly from traditional, conventional packaging, making the path of the pull tabs complex and difficult to determine. Due to the irregular shape of irregularly shaped packaging, the path of the pull tabs needs to be specially designed and adjusted according to the specific packaging shape. Most existing automated packaging equipment is designed for conventionally shaped packaging and struggles to adapt to the uncertainty of the pull tab path in irregularly shaped packaging. This leads to problems such as pull tab misalignment and breakage during automated packaging, reducing packaging efficiency and product quality, and increasing production costs. Utility Model Content

[0004] The purpose of this invention is to provide a pull belt direction control device and an automatic packaging equipment to solve the problem that most of the existing automated packaging equipment is designed for conventionally shaped packaging and is difficult to adapt to the uncertainty of the pull belt direction in irregularly shaped packaging. This leads to problems such as pull belt deviation and breakage during the automated packaging process, which reduces packaging efficiency and product quality and increases production costs.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] On the one hand, a belt guiding control device is provided, comprising:

[0007] Negative pressure components;

[0009] A robotic arm is located around the packaging station. The straw is fixed to the robotic arm. The robotic arm can swing in the horizontal and vertical directions to move the straw, thereby moving the pull strap to control the direction of the pull strap.

[0010] As an optional technical solution for the belt guiding control device, the belt guiding control device further includes a support frame, which is disposed in the buffer section, and the suction tube is fixed to the robotic arm through the support frame.

[0011] As an optional technical solution for the belt guiding control device, the support frame is provided with a mounting hole, and the robotic arm is provided with a threaded hole. The threaded hole corresponds to the position of the mounting hole. After the fastener passes through the mounting hole, it is screwed into the threaded hole to fix the support frame to the robotic arm.

[0012] As an optional technical solution for the belt guiding control device, the mounting hole is set as an elongated hole, and the fastener can change the mounting position in the mounting hole to adjust the position of the support frame relative to the robotic arm.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] In existing technologies, the shape and structure of irregularly shaped packaging differ significantly from traditional conventional packaging, making the path of the pull strap on irregularly shaped packaging complex and difficult to determine. Due to the irregular shape of irregularly shaped packaging, the path of the pull strap on the packaging needs to be specially designed and adjusted according to the specific packaging shape. However, most existing automated packaging equipment is designed for conventionally shaped packaging and is difficult to adapt to the uncertainty of the pull strap path in irregularly shaped packaging. This leads to problems such as pull strap deviation and breakage during automated packaging, reducing packaging efficiency and product quality, and increasing production costs.

[0032] To address the aforementioned problems, this embodiment provides an automated packaging device, including a conveyor belt direction control device. (See reference...) Figures 1-3The pull-belt direction control device includes a negative pressure component, a suction tube 10, and a robotic arm. The suction tube 10 is located at the top of the packaging station and includes a connecting section 11, a buffer section 12, and an extraction section 13, which are connected sequentially. A vent is provided at the end of the connecting section 11, and an adsorption hole is provided at the end of the extraction section 13. The vent is connected to the negative pressure component. The buffer section 12 buffers the airflow from the negative pressure component, and the adsorption hole adsorbs the pull-belt. The robotic arm is located around the perimeter of the packaging station, and the suction tube 10 is fixed to the robotic arm. The robotic arm can swing horizontally and vertically to move the suction tube 10, thereby moving the pull-belt and controlling its direction. By adsorbing the pull-belt with negative pressure and then moving the suction tube 10 with the robotic arm, the direction of the pull-belt is controlled, ensuring its stability to adapt to the automatic packaging equipment. This reduces problems such as pull-belt deviation and breakage, improving packaging efficiency and product quality.

[0033] Specifically, the negative pressure component can be a vacuum pump and its supporting parts or an air compressor, etc. Since the negative pressure component is existing technology, it will not be described in detail here. Specifically, the ability of the robotic arm to swing in both horizontal and vertical directions is also existing technology, and its specific structure and principle will not be explained here.

[0034] In this embodiment, the robotic arm can move the suction tube 10 vertically downwards, allowing the pull strap to enter the adsorption range. After the pull strap is adsorbed by the suction tube 10, the robotic arm moves horizontally to move the suction tube 10, controlling the direction of the pull strap. Then, the robotic arm rises vertically, moving the suction tube 10 upwards, allowing the pull strap to fall off the adsorption range of the suction tube 10 and fall back down under its own weight, thus controlling the direction of the pull strap. Specifically, the buffer section 12 is set as an "S"-shaped arc tube arranged horizontally to buffer the airflow of the negative pressure component and avoid excessive adsorption force causing airflow chaos. Since most of the pull strap is long and narrow, the extraction section 13 is set as a cuboid, making the shape of the adsorption hole rectangular to adapt to the shape of the pull strap. Specifically, the adsorption end face of the adsorption hole is inclined. The inclined adsorption end face facilitates the creation of a gap between the pull strap and the adsorption end face when the suction tube 10 rises, thus facilitating the pull strap to detach from the suction tube 10.

[0035] Furthermore, the guide belt direction control device also includes a support frame 20, which is located in the buffer section 12. The suction tube 10 is fixed to the robotic arm via the support frame 20. Specifically, the support frame 20 has a mounting hole 21, and the robotic arm has a threaded hole. The threaded hole corresponds to the mounting hole 21. Fasteners pass through the mounting hole 21 and are screwed into the threaded hole to fix the support frame 20 to the robotic arm. In this embodiment, the mounting hole 21 is an elongated hole, allowing the fastener to change its installation position in the mounting hole 21 to adjust the position of the support frame 20 relative to the robotic arm. In this embodiment, there are two mounting holes 21, respectively located on both sides of the buffer section 12.

[0036] Specifically, the support frame 20 includes an L-shaped flat surface and a curved surface, and the support frame 20 is integrally formed with the straw 10. Specifically, the curved surface of the support frame 20 is connected to the buffer section 12. In this embodiment, the straw 10 and the support frame 20 are manufactured using 3D printing technology. In other embodiments, the straw 10 and the support frame 20 can also be injection molded. In this embodiment, the straw 10 and the support frame 20 are made of transparent photosensitive resin. The transparent material facilitates the operator's observation of the pull strap's condition.

[0037] The pull-belt direction control device provided in this embodiment also includes a motor with braking function to work in conjunction with it, ensuring that the straw 10 can automatically return to its initial position no matter what situation the machine needs to stop. This effectively avoids the straw 10 moving to its extreme position, which would require manual reset to the starting position before the machine can be restarted. This improves the convenience and safety of operation, reduces production delays caused by downtime, and further enhances the automation level and efficiency of the tobacco packaging process.

[0038] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
