Description

Technical Field

[0001] This application relates to the field of labeling and packaging equipment technology, and in particular to cushioning devices and labeling equipment. Background Technology

[0002] When labeling bottles using labeling equipment, a continuous conveyor belt feeding method is typically used to improve work efficiency. However, labeling equipment in this technology often results in multiple bottles accumulating at the feeding point, leading to bottle crushing and breakage. Utility Model Content

[0003] Therefore, it is necessary to provide a buffer device and labeling equipment to address the problem that labeling equipment in related technologies often causes multiple bottles to accumulate at the feeding position, leading to bottle crushing and damage.

[0004] According to one aspect of this application, a buffer device is provided, the buffer device comprising:

[0005] Base;

[0006] A buffer assembly, disposed on the base, is movable relative to the base along a first direction; the buffer assembly includes a buffer member having a buffer surface extending along a second direction; and

[0007] At least one elastic element is provided between the base and the limiting component, the elastic element extending along the first direction;

[0008] The first direction and the second direction intersect each other.

[0009] In one embodiment, the buffer device further includes a guide rod disposed on the base and extending along the first direction, and the buffering component disposed on the guide rod and movable relative to the guide rod along the first direction.

[0010] In one embodiment, the buffer device further includes a limiting member disposed on the guide rod and movable relative to the guide rod in the first direction, the limiting member being connected to at least one end of an elastic member away from the buffer assembly.

[0011] In one embodiment, the base has a first end and a second end opposite each other along a first direction, and the buffer device includes at least two of the elastic elements, one of which is located between the first end and the buffering component, and the other of which is located between the second end and the buffering component.

[0012] In one embodiment, the limiting member is located between the second end and the corresponding elastic member.

[0013] In one embodiment, an elastic element is fitted onto the guide rod.

[0014] In one embodiment, the buffer assembly further includes a slider disposed on the guide rod and movable relative to the guide rod in a first direction, the buffer being connected to the slider.

[0015] In one embodiment, the buffer assembly further includes a connector and a rolling bearing, the connector being connected between the slider and the buffer, the rolling bearing being sleeved on the connector, and a portion of the rolling bearing being capable of rolling relative to the connector.

[0016] In one embodiment, the intersection of the buffer surface and the reference plane is a curve, wherein the reference plane is parallel to the first direction and the second direction.

[0017] According to another aspect of this application, a labeling device is provided, including the buffer device in any of the above embodiments.

[0018] The aforementioned buffer device continuously feeds bottles along a first direction. A buffer surface extending along a second direction blocks the continuous feeding of multiple bottles, slowing down the feeding progress and preventing bottle accumulation that could lead to breakage. Simultaneously, the elasticity of the elastic element and the design of the limiting and buffering component, which can move relative to the base along the first direction, allow the buffer to not only limit and slow the feeding progress of the bottles but also provide cushioning. It can be understood that when bottles are conveyed and fed, they are blocked by the buffer and may bump against it. If the buffer were to make a hard contact with the bottle, it could easily cause the bottle to break. However, by utilizing the elasticity of the elastic element, the buffer can move relative to the base along the first direction when it collides with the bottle, further reducing the risk of bottle breakage.

[0026] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0027] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, 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, and therefore should not be construed as a limitation of this application.

[0028] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., 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, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0031] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0032] During bottle labeling and packaging, a conveyor belt on a loading platform is typically used to load multiple bottles simultaneously onto the conveyor belt, which then transports them to the labeling location. However, since the subsequent labeling operation requires labeling each bottle individually, the speed of the conveyor belt, which can transport multiple bottles at once, is obviously slower than the speed of the conveyor belt. This leads to bottle accumulation near the labeling location, which can easily cause multiple bottles to collide, be squeezed, or even break.

[0033] Based on this, this application provides a buffer device that can reduce the risk of crushing during bottle feeding.

[0034] See Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 This is a schematic diagram of the structure of the buffer device 10 in one embodiment of this application. Figure 2 This is a schematic diagram of the structure of the buffer device 10 in one embodiment of the present application, located at the material inlet position of the labeling equipment. Figure 3 for Figure 2 The diagram shows the structure of the buffer device 10 installed on the loading plate 9 of the labeling equipment.

[0035] The buffer device 10 includes a base 1, a buffer component, and at least one elastic element 3. When the buffer device 10 is installed on the loading plate 9 of the labeling equipment, it is mainly installed on the loading plate 9 through the base 1.

[0036] The buffer assembly includes a buffer member 2, which has a buffer surface extending along the second direction F2. The bottles are continuously fed along the first direction F1 by the conveyor belt on the feeding platform 9. The buffer member 2 blocks and limits the feeding progress of the bottles, slowing down the accumulation of bottles and preventing them from easily bursting.

[0037] The buffer assembly is mounted on the base 1 and is movable relative to the base 1 along a first direction F1. An elastic member 3 extends along the first direction F1 between the base 1 and the buffer assembly, wherein the first direction F1 and the second direction F2 intersect each other. Thus, through the elastic action of the elastic member 3 and the design that the buffer assembly can move relative to the base 1 along the first direction F1, the buffer member 2 can not only limit and slow down the feeding progress of the bottle, but also buffer the bottle. Furthermore, the adjustable elasticity of the elastic member 3 facilitates adaptation to bottles of different sizes and shapes, improving the versatility and flexibility of the buffer device 10.

[0038] The buffer device 10 of this application slows down the feeding process of the bottle by blocking the buffer member 2, preventing accumulation and crushing damage. When the bottle hits the buffer member 2, the buffer member 2, utilizing the elasticity of the elastic member 3, can move relative to the base 1 in the first direction F1 for cushioning. Compared to the buffer member 2 directly contacting the bottle, which easily causes breakage, the buffer device 10 of this application effectively cushions the bottle, further reducing the risk of breakage and effectively reducing production losses. Moreover, this cushioning effect not only protects the integrity of the bottle but also reduces debris cleanup work on the production line, lowering equipment maintenance costs.

[0039] In some embodiments, in conjunction with reference Figure 1 and Figure 3 As shown, the buffer device 10 also includes a guide rod 4, which is mounted on the base 1 and extends along the first direction F1. The buffering component is mounted on the guide rod 4 and can move relative to the guide rod 4 along the first direction F1. The guide rod 4 provides a stable motion trajectory for the buffering component, ensuring its linear movement along the first direction F1, thereby improving the blocking and buffering effect of the buffer 2 on the bottle and ensuring the stability of the bottle feeding.

[0040] In some embodiments, see Figure 1As shown, the buffer device 10 also includes a limiting member 5, which is disposed on the guide rod 4 and can move relative to the guide rod 4 along the first direction F1. The limiting member 5 is connected to at least one end of the elastic member 3 away from the buffering assembly. The design of the limiting member 5 can effectively limit the extension range of the elastic member 3. By adjusting the position of the limiting member 5 on the guide rod 4 along the first direction F1, the extension range of the elastic member 3 and the range of motion of the buffering assembly along the first direction F1 can be adjusted, thereby adjusting the elastic strength of the elastic member 3, thus adapting it to bottles of different sizes and improving the versatility and flexibility of the buffer device 10.

[0041] For bottles with large radial dimensions and large mass, the adjusting limiting member 5 can be controlled to move along the first direction F1 on the guide rod 4 towards the side closer to the elastic member 3, so that the compression of the elastic member 3 increases, thereby increasing its force on the limiting component to cope with bottles with large radial dimensions and large mass. This allows the buffer device 10 to provide appropriate buffering force for large-sized and large-mass bottles, avoiding the inability to successfully limit the bottle due to insufficient buffering force, which would lead to bottle accumulation and compression.

[0042] For bottles with smaller radial dimensions and lighter weight, the adjusting limit member 5 can be controlled to move along the first direction F1 on the guide rod 4 towards the side away from the elastic member 3, reducing the compression of the elastic member 3 and thus reducing its force on the buffer assembly. This is suitable for bottles with smaller radial dimensions and lighter weight. The buffer device 10 can thus provide appropriate buffering force for small-sized, lightweight bottles, preventing the bottle from colliding and breaking due to excessive buffering force.

[0043] Through the above adjustments, the elastic strength of the elastic element 3 can be flexibly adjusted, thereby improving the versatility and flexibility of the buffer device 10.

[0044] In some embodiments, see Figure 1 and Figure 3 As shown, the base 1 has a first end and a second end opposite to each other along the first direction F1. The buffer device 10 includes at least two elastic elements 3, one of which is located between the first end and the buffer assembly, and the other is located between the second end and the buffer assembly. This symmetrical arrangement of elastic elements 3 can provide a more uniform buffering force, making the buffer assembly more evenly stressed when moving along the first direction F1, thereby improving the overall buffering performance of the buffer device 10.

[0045] In some embodiments, see Figure 1 As shown, the limiting member 5 is located between the second end and the corresponding elastic member 3. This arrangement helps to optimize the internal spatial structure of the buffer device 10, making the cooperation between the components more compact and reasonable.

[0046] In some embodiments, see Figure 1 and Figure 3 As shown, the elastic element 3 is sleeved on the guide rod 4. This not only saves space, but also ensures that the extension and retraction of the elastic element 3 is consistent with the guiding direction of the guide rod 4, ensuring that the transmission of buffering force is more direct and effective, and improving the response speed and buffering effect of the buffer device 10.

[0047] In some embodiments, see Figure 1 and Figure 3 As shown, the buffer assembly also includes a slider 6, which is mounted on the guide rod 4 and can move relative to the guide rod 4 in the first direction F1. The buffer 2 is connected to the slider 6. It can be understood that the cooperation between the slider 6 and the guide rod 4 can reduce the friction force when the buffer assembly moves, improve the smoothness and accuracy of its movement, and enable the buffer 2 to respond more sensitively to the impact of the bottle and provide a more precise buffering effect.

[0048] In some embodiments, such as Figure 1 The buffer assembly also includes a connector 7 and a rolling bearing 8. The connector 7 is connected between the slider 6 and the buffer 2, and the rolling bearing 8 is sleeved on the connector 7, with a portion of the rolling bearing 8 capable of rolling relative to the connector 7. This can be understood in conjunction with further reference. Figure 3 As shown, the buffer 2 typically has a certain mass. The connecting piece 7, being connected between the buffer 2 and the slider 6 for an extended period, is susceptible to bending due to the mass of the buffer 2. Furthermore, the mass of the buffer 2 can cause the connection between the buffer 2 and the connecting piece 7, or between the connecting piece 7 and the slider 6, to detach or break. All of these factors affect the service life of the buffer device 10 and its blocking effect on the bottle. This application addresses this by incorporating a rolling bearing 8 on the connecting piece 7. When the buffer device 10 is installed on the loading plate 9 of the labeling equipment, the rolling bearing 8 abuts against the loading plate 9, thereby supporting the connecting piece 7 and ultimately supporting the buffer 2. This reduces the impact of the buffer 2's gravity.

[0049] Meanwhile, since part of the rolling bearing 8 can rotate relative to the connecting member 7, as the buffer member 2 moves relative to the base 1 and the loading plate 9 along the first direction F1, the rolling bearing 8 begins to roll, thus not affecting the movement of the buffer member 2 in the first direction F1.

[0050] In this embodiment, the rolling bearing 8 includes an inner ring, an outer ring, and balls disposed between the inner and outer rings. The inner ring is fixedly connected to the connecting member 7, and the balls allow the inner and outer rings to rotate relative to each other. Thus, the term "part" in "rolling bearing 8" refers to the outer ring of the rolling bearing 8. The rolling bearing 8 thus supports the buffer member 2 without affecting its movement along the first direction F1.

[0051] In some embodiments, such as Figure 1, Figure 2 and Figure 3 As shown, the intersection of the buffer surface and the reference plane is a curve, where the reference plane is parallel to the first direction F1 and the second direction F2. Thus, the curved buffer surface not only effectively limits the bottle and slows its feeding speed, but also guides the bottle, allowing it to transition smoothly at the buffer device 10, further reducing the risk of breakage due to collision.

[0052] This application also provides a labeling device, see reference. Figure 2 and Figure 3 As shown, the labeling equipment provided in this application includes the buffer device 10 in any of the above embodiments. The labeling equipment also includes a loading platform 9 and a conveyor belt. The conveyor belt is disposed on the loading platform 9 and is used to convey and drive the bottle body along the first direction F1 for loading the bottle body. The buffer device 10 is disposed on the loading platform 9, and the buffer member 2 of the buffer device 10 is located on the side of the conveyor belt facing the bottle body, so that the buffer member 2 can properly limit the bottle body. The outer ring of the rolling bearing 8 of the buffer device 10 abuts against the loading platform 9 or directly against the conveyor belt, so that it can provide support for the buffer member 2.

[0053] The buffer device 10 of this application can effectively limit the bottle body, reduce the risk of bottle crushing and breakage, and cushion the bottle body to further reduce the risk of bottle breakage. This helps protect the integrity of the bottle body, reduces debris cleanup work on the production line, and lowers equipment maintenance costs.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
