Description

Technical Field

[0001] This application relates to the field of cigarette packaging machine technology, and in particular to a label paper conveying pallet positioning device for a packaging machine. Background Technology

[0002] Cigarette factories use packaging machines to package cigarette products during the production process, which includes conveying the label paper. The label paper involves multiple conveying steps, such as... Figure 1 As shown, this is one step in the lifting and conveying of the label paper. Multiple modules 1-2 are installed on the conveyor belt 1-1. The label paper is held between two adjacent modules 1-2. The conveyor belt 1-1 then runs, conveying the label paper to the area below two pallets 1-3. At this point, the conveyor belt 1-1 temporarily stops, and other components transfer the label paper between the corresponding two modules 1-2 to the two pallets 1-3. During the upward transfer of the label paper, the two pallets 1-3 swing outwards under the rotation of the drive shaft 1-4, allowing the label paper to rise. After the label paper reaches the designated position, the two drive shafts 1-4 drive the two pallets 1-3 to swing and move closer together, so that the crossarms of the pallets 1-3 can support the raised label paper. The label paper is then lifted from the pallets 1-3. The paper is then transferred to the next workstation, and the conveyor belt 1-1 continues to run, so that the next label paper is transported to the bottom of the two pallets 1-3. This process is repeated. During the process of transferring the label paper from the conveyor belt 1-1 to the pallet 1-3, the gap between the vertical arms of the two pallets 1-3 and the gap between the two pallets 1-3 need to be aligned to ensure that the label paper is transferred smoothly to the pallet 1-3. When adjusting, the position of the two adjacent modules 1-2 on the conveyor belt in the stopped state is usually used as the reference. Then, the position of the pallet 1-3 on the drive shaft 1-4 is adjusted to meet the above requirements. However, during the adjustment process, because the space at the pallet 1-3 is small, and the vertical arm of the pallet 1-3 is separated from the module 1-2 by the horizontal arm of the pallet 1-3, it is inconvenient to position, and the adjustment process is very troublesome. Utility Model Content

[0003] The purpose of this application is to provide a label paper conveying pallet positioning device for a packaging machine. This device can easily realize the positioning and adjustment of the label paper pallet, thereby effectively solving the shortcomings of the prior art.

[0004] Therefore, this application provides a label paper conveying pallet positioning device for a packaging machine, comprising:

[0005] A first positioning element, wherein the first positioning element is provided with a first positioning surface and a second positioning surface, the first positioning surface and the second positioning surface are arranged opposite to each other;

[0006] The second positioning element is provided with a third positioning surface and a fourth positioning surface, which are arranged opposite to each other.

[0007] A connector is provided, wherein the first positioning element and the second positioning element are connected by the connector;

[0008] Wherein, the first positioning surface and the second positioning surface are arranged along the first direction, the third positioning surface and the fourth positioning surface are arranged along the first direction, and in the first direction, the extension dimension of the connector is smaller than the distance between the first positioning surface and the second positioning surface, and the first direction is parallel to the conveying direction of the trademark paper.

[0009] In some possible implementations, the first positioning surface and the second positioning surface are opposite and concentric arcuate surfaces.

[0010] In some possible implementations, the third positioning surface and the fourth positioning surface are opposite and concentric arcuate surfaces.

[0011] In some possible implementations, the first positioning member is provided with a first positioning hole, the second positioning member is provided with a second positioning hole, and the connecting member is provided with a first positioning post and a second positioning post respectively, with the first positioning post passing through the first positioning hole and the second positioning post passing through the second positioning hole.

[0012] In some possible implementations, the axis of the first positioning post, the axis of the second positioning post, the axis of the first positioning hole, and the axis of the second positioning hole are all perpendicular to the first direction.

[0013] In some possible implementations, the first positioning post and the first positioning hole are rotatably connected.

[0014] In some possible implementations, the second locating post and the second locating hole are interference-fitted.

[0015] In some possible implementations, the virtual circle containing the first positioning surface and the second positioning surface is concentric with the first positioning hole.

[0016] In some possible implementations, the virtual circle containing the third and fourth positioning surfaces and the second positioning hole are eccentrically positioned.

[0017] In some possible implementations, both the first and second positioning members are elongated components, and both the first and second positioning members are provided with reduction grooves to reduce structural weight.

Moreover, the first positioning member and the second positioning member are connected by a connector, so that the first positioning member, the second positioning member and the connector form a whole. In the first direction, the size of the connector is smaller than the distance between the first positioning surface and the second positioning surface, so the first positioning member can be positioned on the horizontal arm of the two pallets, and the first positioning surface and the second positioning surface of the first positioning member abut against the vertical arm of the pallets on both sides, and the third positioning surface and the fourth positioning surface of the second positioning member abut against the two adjacent modules below. In this way, the position of the pallet can be easily adjusted. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] like Figures 1-7As shown, this application embodiment provides a label paper conveying pallet positioning device for a packaging machine, applied in a cigarette factory packaging machine. It serves as an auxiliary tool to position and adjust the label paper conveying pallet 1-3 of the cigarette factory packaging machine. When the packaging machine conveys the label paper, it includes a step of raising and conveying the label paper. The lower conveyor belt 1-1 conveys the label paper. Multiple modules 1-2 are arranged on the conveyor belt 1-1. The gap between two adjacent modules 1-2 is used to limit the placement of the label paper. The width of the label paper and the adjacent... The gaps between the two modules 1-2 correspond, and two pallets 1-3 are provided. Each pallet 1-3 is driven to swing by a drive shaft 1-4. Each pallet 1-3 includes a horizontal arm and a vertical arm. The vertical arm is connected to the drive shaft 1-4, and the horizontal arm is used to support the raised label paper. When the label paper moves to the bottom of the two pallets 1-3 under the conveyor belt 1-1, the conveyor belt 1-1 temporarily stops, and then other components lift the label paper upward. At the same time, the drive shaft 1-4 drives the pallets 1-3 to swing, so that the two pallets 1-3 are in contact. The two plates open to allow the label paper to rise. After the label paper is raised to a certain height, the drive shaft 1-4 drives the pallet 1-3 to swing in the opposite direction, causing the two pallets 1-3 to move closer together in opposite directions. This allows the horizontal arms of the two pallets 1-3 to support the label paper. Then, the conveyor belt 1-1 continues to run, repeating the above steps. During this process, in the vertical position, the gap between the vertical arms of the two pallets 1-3 and the gap between the two adjacent modules 1-2 below the conveyor belt 1-1 after it stops must correspond to each other to ensure that the label paper... The pallet 1-3 is smoothly raised. Due to the long-term swinging motion of the pallet 1-3, it needs to be adjusted periodically. However, during the adjustment process, due to the limited space at the pallet 1-3 and the interference of the horizontal arm of the pallet 1-3, the positioning between the vertical arm of the pallet 1-3 and the lower module 1-2 is very inconvenient. Multiple adjustments and test runs are required to complete the positioning. The adjustment process is not convenient. The positioning device of this application aims to enable convenient and quick positioning adjustment of the pallet 1-3, thereby improving the convenience of positioning adjustment of the pallet 1-3.

[0028] The label paper conveying pallet 1-3 positioning device of the packaging machine includes a first positioning component 101, a second positioning component 102, and a connecting component 200. The first positioning component 101 is provided with a first positioning surface 301 and a second positioning surface 302, which are arranged opposite to each other. The second positioning component 102 is provided with a third positioning surface 303 and a fourth positioning surface 304, which are also arranged opposite to each other. The first positioning component 101 and the second positioning component 102 are connected by the connecting component 200. A first direction is set, which is parallel to the conveying direction of the label paper. Specifically, the first direction is parallel to the conveying direction of the label paper on the lower conveyor belt 1-1, taking the conveying direction of the conveyor belt 1-1 as a horizontal left-right direction. The first positioning surface 301 and the second positioning surface 302 are arranged along the first direction. The third positioning surface 303 and the fourth positioning surface 304 are arranged opposite to each other. Positioning surfaces 303 and 304 are arranged along the first direction. In the first direction, the extension dimension of the connector 200 is smaller than the distance between the first positioning surface 301 and the second positioning surface 302. That is, in the vertical projection, the length of the connector 200 in the first direction is smaller than the distance between the first positioning surface 301 and the second positioning surface 302. Thus, when the two pallets 1-3 swing to a state where they can hold the trademark paper, the first positioning component 101 can be positioned on the horizontal arm of the two pallets 1-3, the connector 200 can extend downward through the gap between the horizontal arms of the two pallets 1-3, and the second positioning component 102 can be positioned in the gap between the two modules 1-2 on the lower conveyor belt 1-1. Thus, by positioning the first positioning component 101 and the second positioning component 102, the positioning between the two pallets 1-3 and the two adjacent modules 1-2 below can be achieved. The operation is convenient and quick, and the adjustment can be completed in one positioning.

[0029] Preferably, the first positioning surface 301 and the second positioning surface 302 are opposite and concentric arc-shaped surfaces, and the third positioning surface 303 and the fourth positioning surface 304 are opposite and concentric arc-shaped surfaces. More preferably, the first positioning member 101 and the second positioning member 102 are both elongated members. The first positioning member 101 is an elongated member, and the first positioning surface 301 and the second positioning surface 302 are located at the outermost ends of the first positioning member 101 along its length. The first positioning member 101 has a long plate-like structure, and the first positioning surface 301 and the second positioning surface 302 are the end faces of the first positioning member 101 along its length, respectively. Both the first positioning surface 301 and the second positioning surface 302 are arc-shaped surfaces. The plane on which the first positioning element 101 is located is a horizontal plane. The axis of the virtual ring on which the arc-shaped surfaces of the first positioning surface 301 and the second positioning surface 302 are located is vertical. Thus, when positioning the first positioning element 101 between the vertical arms of the two pallets 1-3, the positioning of the pallets 1-3 can be completed simply by ensuring that the first positioning surface 301 and the second positioning surface 302 abut against the vertical arms on both sides. Even if the first positioning element 101 has a slight angular deviation, the positioning gap width remains accurate. The diameter of the virtual ring containing the second positioning surface 302 is sufficient. This improves the convenience and tolerance of positioning adjustment. Similarly, the second positioning component 102 is an elongated member, with the third positioning surface 303 and the fourth positioning surface 304 located at the outermost ends of the second positioning component 102 along its length. The second positioning component 102 is also a long plate-shaped structure. The third positioning surface 303 and the fourth positioning surface 304 are the end faces of the second positioning component 102 along its length, respectively. Both the third positioning surface 303 and the fourth positioning surface 304 are curved surfaces. The plane containing the second positioning component 102 is a horizontal plane. The axis of the virtual ring where the third positioning surface 303 and the fourth positioning surface 304 are located is vertical. Therefore, after the second positioning component 102 is positioned between the two adjacent modules 1-2 below, the positioning of the module 1-2 can be achieved as long as the third positioning surface 303 and the fourth positioning surface 304 abut against the modules 1-2 on both sides. That is, even if the second positioning component 102 has a slight angular deviation, the gap between the two adjacent modules 1-2 is still accurate. As long as the diameter of the virtual ring where the third positioning surface 303 and the fourth positioning surface 304 are located is determined, the convenience of positioning adjustment and the fault tolerance rate are further improved.

[0030] like Figure 6 The diagram shown illustrates the usage status of the positioning device.

[0031] In some embodiments, the first positioning member 101 is provided with a first positioning hole 1011, the second positioning member 102 is provided with a second positioning hole 1021, and the connecting member 200 is provided with a first positioning post 201 and a second positioning post 202. The first positioning post 201 passes through the first positioning hole 1011, and the second positioning post 202 passes through the second positioning hole 1021. In this embodiment, the first positioning member 101 is connected to the second positioning member 102 through the connecting member 200. The first positioning post 201 on the connecting member 200 can pass through the first positioning hole 1011 of the first positioning member 101, and the second positioning post 202 on the connecting member 200 can pass through the second positioning hole 1021 of the second positioning member 102, thereby realizing the connection between the first positioning member 101 and the second positioning member 102. The connection is made more convenient by using a hole-type plug-in method.

[0032] More preferably, the axis of the first positioning post 201, the axis of the second positioning post 202, the axis of the first positioning hole 1011, and the axis of the second positioning hole 1021 are all perpendicular to the first direction. In this way, the first positioning member 101, the connecting member 200, and the second positioning member 102 are formed into an I-shape, which makes the positioning accurate and convenient.

[0033] Preferably, the first positioning post 201 and the first positioning hole 1011 are rotatably connected, and the second positioning post 202 and the second positioning hole 1021 are interference-fitted. This allows the first positioning member 101 to rotate relative to the connecting member 200, while the second positioning member 102 is fixed relative to the connecting member 200. During positioning, the connecting member 200 and the second positioning member 102 can be placed together between the two modules 1-2, and the fastening bolts between the support plate 1-3 and the drive shaft can be loosened. Then, the connecting member 200 is allowed to pass upward through the gap between the cross arms of the two support plates 1-3, and then... The first positioning member 101 is connected to the first positioning post 201 at the top of the connector 200, so that the length directions of the first positioning member 101 and the second positioning member 102 are parallel to the first direction. Then, the position of the tray 1-3 on the drive shaft is adjusted so that the trays 1-3 on both sides abut against the first positioning surface 301 and the second positioning surface 302 respectively, thus completing the positioning adjustment of the tray 1-3. This makes it more convenient to operate in a narrow space and allows the first positioning member 101 to swing at a certain angle relative to the second positioning member 102, making the positioning adjustment more convenient.

[0034] More preferably, the virtual circle containing the first positioning surface 301 and the second positioning surface 302 is concentric with the first positioning hole 1011, while the virtual circle containing the third positioning surface 303 and the fourth positioning surface 304 is eccentric with the second positioning hole 1021.

[0035] In practice, the gap between the two modules 1-2 on conveyor belt 1-1 is 2 mm larger than the width of the label paper, and the gap between the vertical arms of the two pallets 1-3 is 0.2 mm larger than the width of the label paper. For positioning, when other components vertically raise the label paper on conveyor belt 1-1 between the two pallets 1-3, more precisely, the width of the label paper needs to be aligned with the gap between the inner walls of the vertical arms of the two pallets 1-3. Only in this way can the label paper and the pallets 1-3 be precisely aligned. When conveyor belt 1-1 is conveying the label paper, after conveyor belt 1-1 stops, under the action of inertia, the label paper will rush forward and hit the side wall of the front module 1-2. Figure 7 As shown, in order to align the label paper with the vertical arms of the two pallets 1-3, theoretically, in the first conveying direction, when the conveyor belt 1-1 stops, the inner side of the downstream module 1-2 of the two lower modules 1-2 should lag behind the inner side of the vertical arm of the upstream downstream pallet 1-3 by 0.1 mm. Therefore, there needs to be a deviation between the vertical center line between the two adjacent modules 1-2 and the vertical center line between the inner sides of the vertical arms of the two pallets 1-3. This deviation is 1 mm. In this way, when the conveyor belt 1-1 stops, the label paper can be aligned with the two pallets 1-3 above.

[0036] Therefore, in this embodiment, the connector 200 is arranged in an axial shape. The overall axis of the connector 200, the axis of the first positioning post 201, and the axis of the second positioning post 202 coincide. The axis of the virtual ring where the first positioning surface 301 and the second positioning surface 302 are located is coaxial with the first positioning hole 1011. Thus, the axis of the virtual ring where the third positioning surface 303 and the fourth positioning surface 304 are located and the axis of the second positioning hole 1021 are offset from each other. The distance of this eccentricity is the same as the above-mentioned deviation value, which is 1 mm. Figure 4 The interval between dashed lines A and B is such that, in the conveying direction of conveyor belt 1-1, the axis of the virtual ring where the third positioning surface 303 and the fourth positioning surface 304 are located is closer to the upstream than the axis of the second positioning hole 1021. The alignment direction of the axis of the virtual ring where the third positioning surface 303 and the fourth positioning surface 304 are located and the axis of the second positioning hole 1021 is the first direction. In this way, the correspondence between the two pallets 1-3 and the two modules 1-2 can meet the centering requirements of the trademark paper.

[0037] More preferably, an indicator arrow 400 is provided on the second positioning member 102. The direction of the indicator arrow 400 is the direction in which the conveyor belt 1-1 conveys the trademark paper. For the second positioning member 102, in the direction of the indicator arrow 400, the axis of the virtual ring where the third positioning surface 303 and the fourth positioning surface 304 are located is upstream of the axis of the second positioning hole 1021, and the deviation distance is 1 mm. Therefore, when the second positioning member 102 is positioned between the two adjacent modules 1-2 below, the direction of the indicator arrow 400 corresponds to the conveying direction of the conveyor belt 1-1, thus making positioning more convenient.

[0038] More preferably, both the first positioning member 101 and the second positioning member 102 are provided with a reduction groove 500 to reduce the structural weight. In this embodiment, both the first positioning member 101 and the second positioning member 102 are elongated components. The reduction groove 500 is provided at the lower part of the first positioning member 101 and the lower part of the second positioning member 102. The reduction groove 500 is recessed and avoids the position areas of the first positioning surface 301, the second positioning surface 302, the third positioning surface 303, the fourth positioning surface 304, the first positioning hole 1011, and the second positioning hole 1021. This not only reduces the structural weight but also avoids affecting the connection strength between the components and avoids the phenomenon of inaccurate positioning caused by the contact surface being too narrow during positioning. The contact surface being too narrow here refers to the contact between the first positioning surface 301 and the second positioning surface 302 and the vertical arm of the support plate 1-3, and the contact between the third positioning surface 303 and the fourth positioning surface 304 and the module 1-2.
