Abstract
Description
Technical Field
[0001] This utility model relates to the field of product packaging technology, and in particular to a paper collection start / stop device and labeling system. Background Technology
[0002] To facilitate product transportation, products are typically packaged in batches into boxes before leaving the factory. During the packaging process, labels containing product information or promotional information are affixed to the outside of the boxes. In current labeling systems, labels are adhered to slips of paper and conveyed sequentially by multiple rollers. After labeling, any remaining slips of paper are wound up onto the last winding roller, which is continuously rotated by a winding motor to rewind the slips. However, the upstream slips of paper are intermittently conveyed downstream. When the upstream slips of paper stop conveying, they are prone to breakage under the significant drag force of the winding motor. If a breakage occurs, the labeling system must be paused, and the slips of paper must be manually reconnected to the last roller, impacting production efficiency. Utility Model Content

[0029] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0032] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0033] The first aspect of this utility model is to provide a paper receiving start / stop device, such as... Figures 1 to 3 As shown, it includes a roller assembly 1, an elastic guide assembly 2, a winding assembly 3, and a detection and control assembly connected to the winding assembly 3;
[0034] The roller assembly 1 is slidably engaged with the elastic guide assembly 2. The roller assembly 1 has a first limit position away from the winding assembly 3 and a second limit position close to the winding assembly 3 relative to the elastic guide assembly 2. The elastic guide assembly 2 is configured to apply a spring force to the roller assembly 1 to prevent the roller assembly 1 from moving to the second limit position.
[0035] The detection control component is configured to control the rotation of the winding component 3 when the elastic guide component 2 slides to the first limit position and to control the winding component 3 to stop rotating when the elastic guide component 2 slides to the second limit position.
[0036] by Figure 2 and Figure 3 The following is a detailed explanation of the operation of the above-mentioned paper receiving start / stop device:
[0037] like Figure 2 As shown, at this time, roller assembly 1 is in the second extreme position, and winding assembly 3 stops rotating. When the paper 7 moves along... Figure 2 When the paper is fed to roller assembly 1 in the direction indicated by the middle arrow, the paper label 7 is in a relaxed state and does not pull on roller assembly 1. Under the elastic force of elastic guide assembly 2, roller assembly 1 gradually moves to the left until it reaches the desired position. Figure 3 When the roller assembly 1 reaches the first limit position, the detection and control component controls the winding assembly 3 to rotate counterclockwise. The winding assembly 3 winds up the paper strip. During the winding process, the upstream paper strip 7 stops being fed to the roller assembly 1. The paper strip 7 gradually tightens, and the paper strip 7 on the roller assembly 1 will overcome the elastic force and pull the roller assembly 1 towards the second limit position. Until the roller assembly 1 reaches the second limit position, the detection and control component controls the winding assembly 3 to stop rotating. This cycle continues.
[0038] Compared with the prior art, the paper take-up start-stop device provided in the first aspect of this utility model can control the start and stop of the take-up assembly 3, avoiding the take-up assembly 3 from being in a rotating state all the time. At the same time, during take-up, the roller assembly 1 can continuously slide relative to the elastic guide assembly 2 to adapt to the tension state of the paper 7. This can effectively prevent the paper 7 from being subjected to a large tension force due to the continuous rotation of the take-up assembly 3, making the paper less prone to breakage and improving work efficiency.
[0039] Additionally, when the winding assembly 3 stops rotating, the slip 7 moves along... Figure 2 When the paper is conveyed to the roller assembly 1 in the direction indicated by the middle arrow, it also makes it convenient for personnel to remove the label 7 when needed.
[0040] When the winding assembly 3 includes a winding motor, the above embodiments can also extend the life of the winding motor, and it can stop working when winding is not required or there is no winding allowance.
[0041] In an optional embodiment, the elastic guide assembly 2 includes a guide structure 21 and an elastic element 22, wherein:
[0042] The roller assembly 1 is slidably engaged with the guide structure 21, which guides the sliding of the roller assembly 1 so that the roller assembly 1 can slide in a direction close to or away from the winding assembly 3.
[0043] The elastic element 22 is connected between the guide structure 21 and the roller assembly 1. The elastic element 22 is configured to apply a spring force to the roller assembly 1 so that the roller assembly 1 can be reset to a second limit position away from the winding assembly 3 under the action of the spring force when it is not subjected to the tension of the paper 7.
[0044] The aforementioned elastic guide assembly 2 has a simple structure. The guide structure 21 and the elastic element 22 can respectively guide the roller assembly 1 and apply elastic force, without the need for other power sources that rely on electric power, thus saving device costs.
[0045] Among them, the elastic element 22 can be a helical spring or a torsion spring, etc.
[0046] Preferably, the elastic element 22 is a helical spring.
[0047] In alternative implementations, such as Figure 2 As shown, the guide structure 21 includes a fixed seat 211 and a guide rail 212 connected to the fixed seat 211. The roller assembly 1 is slidably engaged with the guide rail 212, and the two ends of the elastic member 22 abut against the fixed seat 211 and the roller assembly 1, respectively.
[0048] In use, the roller assembly 1 can slide relative to the guide rail 212, such as Figure 3 As shown, when the roller assembly 1 moves to the right under the drive of the paper, the elastic element 22 between the fixed seat 211 and the roller assembly 1 is compressed; as Figure 2 As shown, when the roller assembly 1 moves to the left under the drive of the elastic element 22, the elastic element 22 between the fixed seat 211 and the roller assembly 1 is released.
[0049] Specifically, in order to enable the guide rail 212 to play a better guiding role for the roller assembly 1, the guide rail 212 can be configured as multiple rails, each rail 212 being parallel and spaced apart.
[0050] like Figure 2 As shown, there are two guide rails 212, both of which are connected to the fixed base 211. Both the guide rails 212 and the fixed base 211 can be installed on the platform by screws or other connecting parts.
[0051] In alternative implementations, such as Figure 1 As shown, the roller assembly 1 includes a roller body 11, a sliding seat 12, and a guide rod 13. The roller body 11 is mounted on the sliding seat 12, the sliding seat 12 is slidably engaged with the guide rail 212, the guide rod 13 is connected to the sliding seat 12, the guide rod 13 is parallel to the guide rail 212 and is slidably engaged with the fixed seat 211.
[0052] In use, the sliding seat 12 can slide relative to the guide rail 212, thereby realizing the reciprocating motion of the roller body 11. During this process, the guide rod 13 slides synchronously with the sliding seat 12 relative to the fixed seat 211. The guide rod 13 can also guide the sliding of the sliding seat 12, making the movement of the sliding seat 12 more stable.
[0053] In an optional embodiment, to reduce the friction between the guide rod 13 and the fixed seat 211, a linear bearing is provided between the guide rod 13 and the fixed seat 211 and the sliding seat 12.
[0054] The linear bearing can effectively reduce the friction between the guide rod 13 and the fixed seat 211, extend the life of the guide rod 13, and reduce the moving resistance of the sliding seat 12.
[0055] In alternative implementations, such as Figure 1 As shown, the elastic element 22 is sleeved on the outside of the guide rod 13.
[0056] In the above embodiments, the guide rod 13 not only guides the movement of the sliding seat 12, but also provides an installation position for the elastic element 22, ensuring that the elastic element 22 can be stably pressed between the fixed seat 211 and the sliding seat 12.
[0057] Specifically, the guide rods 13 can be configured as multiple rods, each of which is parallel and spaced apart.
[0058] like Figure 2 As shown, there are two guide rods 13, and both guide rods 13 are connected to the sliding seat 12.
[0059] Specifically, such as Figure 1 As shown, the sliding seat 12 may include an upper sliding seat 121 and a lower sliding seat 122. The lower sliding seat 122 is connected to the guide rod 13, and the upper sliding seat 121 is mounted on the top surface of the lower sliding seat 122 and connected to the roller body 11.
[0060] In alternative implementations, such as Figure 1 As shown, a limiting member 14 is provided on the roller body 11, which is used to limit the axial position of the paper 7 relative to the roller body 11.
[0061] During the transmission of the label 7 on the roller body 11, it may move relative to the roller body 11 along the axial direction of the roller body 11. The limiting member 14 provided in the above embodiment can effectively alleviate the above situation and ensure that the label 7 is transmitted stably on the roller body 11.
[0062] Specifically, the limiting member 14 can be ring-shaped and sleeved on the outside of the roller body 11, and the limiting member and the upper sliding seat 121 can be used to pass the paper 7.
[0063] In alternative implementations, such as Figures 1 to 4As shown, the detection control component includes a first detector 4, a second detector 5, and a controller 6; the first detector 4 is configured to detect a first positioning signal when the elastic guide component 2 slides to a first limit position; the second detector 5 is configured to detect a second positioning signal when the elastic guide component 2 slides to a second limit position; both the first detector 4 and the second detector 5 are connected to the controller 6, and the controller 6 is connected to the winding component 3.
[0064] When using, such as Figure 2 As shown, when the roller assembly 1 reaches the second limit position, the second detector 5 detects the second positioning signal, and the controller 6 controls the winding motor in the winding assembly 3 to stop according to the second positioning signal; as Figure 3 As shown, when the roller assembly 1 reaches the first limit position, the first detector 4 detects the first positioning signal, and the controller 6 controls the winding motor in the winding assembly 3 to drive the winding roller to rotate according to the first positioning signal.
[0065] In the above embodiments, the detection control components include a first detector 4 and a second detector 5, which makes it easier to detect the two extreme positions reached by the roller assembly 1.
[0066] The first detector 4 and the second detector 5 may include proximity switches, infrared sensors or acoustic sensors, etc.
[0067] It is understandable that the principle by which controller 6 switches the working state of the power source according to different position signals is a well-known technology. To save space, the above control principle will not be explained in detail.
[0068] In alternative implementations, such as Figure 1 As shown, the first detector 4 includes a first mounting base 41 and a first sensor 42 mounted on the first mounting base 41. The first mounting base 41 can ensure that the first sensor 42 is stably mounted.
[0069] Similarly, such as Figure 1 As shown, the second detector 5 includes a second mounting base 51 and a second sensor 52 mounted on the second mounting base 51. The second mounting base 51 can ensure that the second sensor 52 is stably mounted.
[0070] The second aspect of this utility model provides a labeling system, which includes the aforementioned paper collection start / stop device.
[0071] The labeling system provided in the second aspect of this utility model has the paper collection start / stop device provided in the first aspect of this utility model, and thus has all the beneficial effects of the paper collection start / stop device provided in the first aspect of this utility model.
[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
