Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of container packaging and conveying equipment, and more specifically, to a special feeding screw for realizing continuous conveying of prismatic containers such as cups, bottles, cans, etc., which is more suitable for further packaging processing such as filling, sealing, sleeve labeling, labeling, and marking. Background Art
[0002] In modern society, the competition for commodities in trade circulation is becoming increasingly fierce. Under the premise of ensuring product quality, the packaging forms of products are also changing with each passing day. In order to increase customers' purchasing desire, many products use outer packaging with unique characteristics. Most of these packaging bottles are non-circular special-shaped bottles. The outside of the hard packaging containers for beverages, wines, etc. on the market are affixed with labels of different shapes and colors. The body and lid of some containers have directional requirements, so that different labels can be affixed in different directions. In order to improve the yield rate of sleeve labeling and labeling and the uniformity of packaging, before the container is sleeved and labeled, it is usually moved to an appropriate rotation phase relative to the equipment, and the container needs to be oriented and arranged in a uniform direction.
[0003] Containers with non-circular cross-sections will affect production efficiency and product quality due to the inability to accurately orient. At present, the traditional processing methods for container orientation mostly use manual alignment and image recognition + robot operation. Manual operation is labor-intensive, inefficient, and difficult to ensure accuracy. Image recognition is used to obtain the relative position deviation of the container, and the robot or clamping rotating device is controlled to control the container's running trajectory or rotation angle to complete the container's orientation operation. The working rhythm is slow and high-speed and stable supply cannot be achieved, resulting in reduced production efficiency. In addition, these devices are complex and costly when installed on the production line, and cannot meet the production requirements of today's product high-speed packaging. Summary of the invention
[0004] In view of the above-mentioned technical problem that the different orientations of containers or bottles lead to inconsistent packaging, a feeding screw is provided for directional arrangement of prismatic containers, thereby achieving directional arrangement of containers and improving production efficiency.
[0005] The technical means adopted by the present invention are as follows:
[0006] A feeding screw for realizing directional arrangement of prismatic containers comprises a screw I and a screw II which are arranged in parallel and can rotate synchronously in opposite directions; a distance capable of accommodating the container is spaced between the screw I and the screw II, and the side surfaces of the container can contact the screw I and the screw II respectively; the feeding screw can convey a plurality of the containers one by one through the rotation of the screw I and the screw II and drive each of the containers to rotate to the same phase during the conveying process, thereby completing the directional arrangement of the plurality of containers.
[0007] Furthermore, the screw rods I and II are divided into a container introduction section I, a container speed change section II, a container orientation section III, a container rotation section IV and a container output section V in sequence along the axial direction;
[0008] The screw grooves in the container introduction section I and the container speed change section II are both arc-shaped and match the size of the circumscribed circle corresponding to the cross section of the container; the container speed change section II is used to increase the contact length between the screw I and the screw II and the container;
[0009] The screw groove in the container orientation section III gradually changes from the arc shape to a transition groove shape matching the cross-sectional shape of the container along the axial direction of the supply screw, and the angle α between the groove surface of the transition groove and the axis of the supply screw is 180 / n, where n represents the number of sides of the cross-sectional shape of the container;
[0010] The screw groove in the container rotation section IV gradually changes from the transition groove to a final groove whose shape matches the cross-sectional shape of the container along the axial direction of the supply screw, and the groove surface of the final groove is parallel to the axis of the supply screw;
[0011] The screw grooves in the container output section V are all the final grooves, which are used to output the container.
[0012] Furthermore, the container introduction section I and the container speed change section II are used to enable the containers of different phases to enter between the screw I and the screw II through the container introduction section I, and to enable the axis of the container entering between the screw I and the screw II to be perpendicular to the plane where the axes of the screw I and the screw II are located;
[0013] The container orientation section III is used to push the container entering between the screw rods I and II to rotate to a transition phase capable of meshing with the transition groove;
[0014] The container rotation section IV is used to further push the container to rotate to a final phase where it can mesh with the final groove shape.
[0015] Furthermore, when the container spacing in the container introduction section I is greater than the circumscribed circle diameter corresponding to the cross section of the container, the number of prism sides n of the container applicable to the feeding screw is ≥3; when the container spacing in the container introduction section I is equal to the circumscribed circle diameter corresponding to the cross section of the container, the number of prism sides n of the container applicable to the feeding screw is ≥5.
[0016] Furthermore, the pitch of the container output section V is determined according to the spacing between the containers required to be output by the downstream equipment of the supply screw, so that the supply screw can meet different output spacing requirements and achieve output of the same phase and spacing for the ventilation.
[0017] Furthermore, the screw rod I and the screw rod II are driven by two sets of identical driving devices to rotate synchronously in opposite directions, and the rotation directions are both toward the direction where the container is located.
[0018] Furthermore, angle sensors for monitoring the rotation direction and angle are respectively installed on the screw rod I and the screw rod II.
[0019] Furthermore, the container is in line contact with the transition groove and the final groove when they are meshed with each other.
[0020] Furthermore, the container is a cup, a bottle or a can.
[0021] Compared with the prior art, the present invention has the following advantages:
[0022] The supply screw for realizing directional arrangement of prismatic containers provided by the present invention has a simple structure and reliable performance, improves the efficiency and accuracy of container orientation, adopts a modular design, has a compact structure, and is low in cost. During the production process, the noise is small and there is no rigid impact, the speed is easy to adjust, and the device is very convenient to assemble and adjust on the production line.
[0023] Based on the above reasons, the present invention can be widely used in daily chemical, medicine, health, food, packaging and other industries to complete high-speed work of coding, filling, bottling and labeling processes. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0032] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0033] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values of the parts and steps described in these embodiments do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.
[0034] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0035] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0036] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
[0037] Example 1
[0038] like Figure 1-4 As shown, the present invention provides a feeding screw for realizing directional arrangement of prismatic containers, comprising a screw Ⅰ1 and a screw Ⅱ2 which are arranged in parallel and can rotate synchronously in opposite directions; a distance capable of accommodating the container 4 is spaced between the screw Ⅰ1 and the screw Ⅱ2, and the side surfaces of the container 4 can contact the screw Ⅰ1 and the screw Ⅱ2 respectively; the feeding screw can convey a plurality of the containers 4 one by one through the rotation of the screw Ⅰ1 and the screw Ⅱ2 and drive each of the containers 4 to rotate to the same phase during the conveying process, thereby completing the directional arrangement of the plurality of containers 4.
[0039] Furthermore, the screw Ⅰ1 and the screw Ⅱ2 are divided into a container introduction section Ⅰ, a container speed change section Ⅱ, a container orientation section Ⅲ, a container rotation section Ⅳ and a container output section Ⅴ in sequence along the axial direction;
[0040] like Figure 1 As shown in P1, the screw grooves in the container introduction section I and the container speed change section II are both arc-shaped and match the size of the circumscribed circle corresponding to the cross section of the container; the container speed change section II is used to increase the contact length between the screw I1 and the screw II2 and the container 4;
[0041] like Figure 1 As shown in P2 and P3, the screw groove in the container orientation section III gradually changes from the arc shape to a transition groove shape matching the cross-sectional shape of the container 4 along the axial direction of the feeding screw, and the angle α between the groove surface of the transition groove and the (horizontal) axis of the feeding screw is 180 / n, where n represents the number of sides of the cross-sectional shape of the container 4;
[0042] The screw groove in the container rotation section IV is gradually changed from the transition groove to a final groove shape matching the cross-sectional shape of the container 4 along the axial direction of the supply screw, and the groove surface of the final groove is parallel to the axis of the supply screw. Figure 1 As shown in P4;
[0043] like Figure 1 As shown in P4, the screw grooves in the container output section V are all the final grooves, which are used for translating the container 4 and can translate at a uniform speed, increase speed or decrease speed to meet different output spacing requirements.
[0044] For prismatic containers with different cross-sectional shapes, the technical solution of the present invention can be used to manufacture matching feeding screws to achieve directional arrangement of different prismatic containers.
[0045] Furthermore, the container introduction section I and the container speed change section II are used to allow the containers 4 of different phases (i.e., the containers 4 whose axes are at any angle to the axial direction of the supply screw) to enter between the screw I1 and the screw II2 through the container introduction section I, and to allow the axes of the containers 4 entering between the screw I1 and the screw II2 to be perpendicular to the plane where the axes of the screw I1 and the screw II2 are located;
[0046] The container orientation section III is used to push the container 4 entering between the screw Ⅰ1 and the screw Ⅱ2 to rotate to a transition phase that can mesh with the transition groove; the containers 4 at different phases can all rotate to the same transition phase at a minimum angle in the container orientation section III;
[0047] The container rotation section IV is used to further push the container 4 to rotate to a final phase capable of engaging with the final groove profile; the containers 4 at different phases can all rotate from the transition phase to the same final phase in the container rotation section IV.
[0048] In the present invention, a vertex on the axial section of the container 4 is used as a tracing point, different phases indicate different positions of the tracing point, and the screw groove type refers to the shape of the axial section of the screw groove.
[0049] Furthermore, when the container spacing in the container introduction section I (the distance between two adjacent screw grooves)>the circumscribed circle diameter corresponding to the cross section of the container 4, the number of prism sides n of the container 4 applicable to the feeding screw is ≥3; when the container spacing in the container introduction section I (the distance between two adjacent screw grooves)=the circumscribed circle diameter corresponding to the cross section of the container 4, the number of prism sides n of the container 4 applicable to the feeding screw is ≥5.
[0050] Furthermore, the pitch of the container output section V is determined according to the spacing between the containers 4 to be outputted by the subsequent equipment of the feeding screw, so that the feeding screw can meet different output spacing requirements and achieve output of the containers 4 with the same phase and spacing.
[0051] Furthermore, the screw I1 and the screw II2 are driven by two identical drive devices to rotate synchronously in opposite directions, and the rotation direction is toward the direction of the container 4, so that the container 4 is subjected to a downward force during the conveying process, which can further ensure the stability of the supply of the container 4. The drive device can be a motor.
[0052] Furthermore, angle sensors for monitoring the rotation direction and angle are respectively installed on the screw rod I1 and the screw rod II2, so as to monitor the rotation of the screw rod I1 and the screw rod II2, thereby timely adjusting the working state of the driving device to ensure that the screw rod I1 and the screw rod II2 rotate synchronously in opposite directions.
[0053] Furthermore, the container 4 is in line contact with the transition groove and the final groove when they are meshed with each other.
[0054] Furthermore, the container 4 may be a hard packaging container such as a cup, a bottle or a can.
[0055] This embodiment takes the conveying of hexagonal prism containers as an example to illustrate the working process of the feeding screw for achieving directional arrangement of prism containers according to the present invention:
[0056] Figure 2 and Figure 3Schematic diagram of the position change of the container in two extreme phases (the tracing point M is on the vertical axis of the cross section and the tracing point N is located on a side perpendicular to the vertical axis of the cross section) during the conveying process in the feeding screw (the tracing point position changes from M1 to M4 as the phase changes), Figure 4 It is a schematic diagram of the position change of the container in any phase during the conveying process in the feeding screw under the non-limit phase (the position of the tracing point Q other than the tracing point M and the tracing point N); M1~M4, N1~N4, Q1~Q4 represent Figures 2 to 4 The trace points in the graph vary with the phase;
[0057] from Figures 2 to 4 It can be seen that since P1 is the arc-shaped screw groove in the container introduction section I and the container speed change section II, the corresponding container outer envelope section 3 is a circle with the same circumscribed circle as the corresponding container cross section, and the hexagonal container entering at any phase can rotate freely in the screw groove at this time; P2 is the screw groove in the transition stage in the container orientation section III, and the corresponding container outer envelope section 3 is a polygon between a circle and a hexagon. The groove in the container orientation section III gradually changes from an arc shape to a transition groove P3 that matches the cross-sectional shape of the hexagonal container, and the corresponding container outer envelope section 3 is a hexagon with the same cross-sectional shape as the hexagonal container. Since the screw groove area gradually decreases, containers at different phases gradually rotate to the same transition phase, which can avoid containers in extreme positions such as Figure 2 and Figure 3 As shown, the container is stuck on the screw and causes rupture, which affects the continuity of production or causes wear to the screw, affecting the service life of the screw; the hexagonal containers entering the screw at different phases are in the container introduction section I, container speed change section II, and container orientation section III of the screw. Under the limitation of the force and groove type applied by the screw on the container, the rotation space gradually decreases until the same transition phase; then the container rotates from the transition phase to the final phase through the container rotation section IV. The final groove type corresponding to the final phase is P4, and the corresponding container outer envelope section 3 is a hexagon with the same cross-sectional shape as the hexagonal container. At the same time, P4 is also the screw groove type when the container output section V outputs. The containers with different initial phases have the same phase in the screw container rotation section IV and the container output section V, so that the directional arrangement of multiple hexagonal containers can be completed.
[0058] Regardless of the initial orientation of the container, the feeding screw of the present invention can enable 100% of the containers standing on the conveyor line to be conveyed to the subsequent packaging equipment in a predetermined direction (phase), so that all containers have the same trademark, coding and other appearance forms. The whole process is continuous, high-speed, stable and impact-free, adapting to the development trend of high-efficiency and high-speed production lines, improving the orientation accuracy and production efficiency of the container, and effectively reducing screw wear and increasing the service life of the screw.
[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
