Description

Technical Field

[0001] This utility model relates to the field of tobacco packaging machinery technology, and in particular to an insertion wheel positioning detection device and a packaging machine. Background Technology

[0002] In the FOCKE-FX2 packaging machine, the 753 label paper conveyor roller receives the label paper sucked from the hopper and smoothly and accurately conveys it into the mold box of the 801 packaging roller (Box Former). The inserting wheel is a key actuator on the 753 roller system. Its core function is to precisely push the "U"-shaped label paper, which has already been folded at the bottom, into the mold box of the 801 packaging roller, preparing it for packaging the cigarette packs; it acts like a precise pusher. Therefore, the positional accuracy of the inserting wheel is extremely important.

[0003] When a cigarette pack blockage occurs, the operator restarts the machine to check for blockage and determine if the insert roller has shifted. If a blockage is found, the insert roller is considered misaligned and its position needs to be redefined to resolve the issue. Even slight misalignment of the insert roller, while not directly causing a blockage in the cigarette pack conveying process, can affect the quality of the cigarette packs (e.g., misalignment or tilting when wrapping the cigarette packs with label paper, resulting in defective packs, curled edges, or slippage). In such cases, the misalignment is difficult to detect, potentially leading to cigarette pack quality issues.

[0004] Therefore, there is an urgent need for an insertion wheel positioning detection device and a packaging machine to solve the above problems. Utility Model Content

[0005] The first objective of this invention is to provide an insert wheel displacement detection device to solve the problem in the prior art that it is difficult to detect slight displacement of the insert wheel, which leads to quality accidents in cigarette packs.

[0006] The second objective of this invention is to provide a packaging machine that facilitates the detection of whether the insertion wheel has shifted, thereby ensuring the quality of the cigarette pack.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] An insertion wheel positioning detection device is used to detect the position of the insertion wheel in a packaging machine. The device includes a mounting frame, a detection baffle, and an inductive proximity switch mounted on the mounting frame. The mounting frame is detachably connected to the fixed bushing of the packaging machine. The detection baffle includes a connecting part and a protrusion connected together. The connecting part is detachably connected to the insertion wheel. On the axial direction of the insertion wheel, the projection of the protrusion is located inside the insertion wheel, and the projection of the protrusion is located outside the insertion wheel. After the insertion wheel completes one working cycle, the inductive proximity switch can detect whether the protrusion is located at a preset position.

[0009] Furthermore, the insertion wheel positioning detection device also includes a stop module. The inductive proximity switch is communicatively connected to the stop module. The inductive proximity switch can send a stop signal to the stop module, and the stop module can control the limit switch of the packaging machine.

[0010] Furthermore, the mounting bracket includes a first bracket, a second bracket, and a first fixing member. The inductive proximity switch is mounted on the first bracket. Both the first bracket and the second bracket are provided with first mounting holes. The first fixing member can pass through and be fixed to the first mounting holes of the first bracket and the second bracket to achieve a detachable connection between the first bracket and the second bracket.

[0011] Furthermore, the first bracket has a mounting portion at one end away from the second bracket, and a second mounting hole is provided on the mounting portion, and the inductive proximity switch is mounted in the second mounting hole.

[0012] Furthermore, there are two first fixing members. Both the first bracket and the second bracket are provided with two first mounting holes. The two first mounting holes of the first bracket are symmetrically arranged on the first bracket, and the two first mounting holes of the second bracket are symmetrically arranged on the second bracket. One of the first fixing members can pass through and be fixed to one of the first mounting holes of the first bracket and one of the first mounting holes of the second bracket, and the other first fixing member can pass through and be fixed to the other first mounting hole of the first bracket and the other first mounting hole of the second bracket.

[0013] Furthermore, the insertion wheel positioning detection device also includes a second fixing member, and the connecting part has a third mounting hole. The second fixing member can pass through and be fixed to the third mounting hole and the insertion wheel, so as to detachably connect the connecting part to the insertion wheel.

[0014] Furthermore, the third mounting hole is an elongated hole.

[0015] Furthermore, a groove is provided at the end of the connecting portion away from the protrusion.

[0016] Furthermore, the edges of both the connecting portion and the protrusion are rounded.

[0017] The packaging machine includes the insertion wheel movement detection device.

[0018] The beneficial effects of this utility model are:

[0019] This invention provides an insert wheel positioning detection device for detecting the position of the insert wheel in a packaging machine. The device includes a mounting frame, a detection baffle, and an inductive proximity switch mounted on the mounting frame. The mounting frame is detachably connected to the fixed bushing of the packaging machine. The detection baffle includes a connecting part and a protrusion connected together. The connecting part is detachably connected to the insert wheel. Axially, the projection of the protrusion is located inside the insert wheel, and the projection of the protrusion is located outside the insert wheel. After the insert wheel completes one working cycle, the inductive proximity switch detects whether the protrusion is in a preset position. During the operation of the insert wheel, after one working cycle, the inductive proximity switch detects whether the protrusion is in the preset position. When the protrusion is detected in the preset position, it indicates that the insert wheel is moving normally and there is no misalignment. When the inductive proximity switch does not detect the protrusion in the preset position, it indicates that the insert wheel has misaligned. This device allows for rapid detection of insert wheel misalignment, even slight misalignment can be quickly detected for timely adjustment, ensuring the quality of the produced cigarette packs.

[0020] This utility model also provides a packaging machine, including the above-mentioned insertion wheel displacement detection device, which facilitates the detection of whether the insertion wheel has shifted, thus ensuring the quality of the cigarette pack. Attached Figure Description

[0028] 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.

[0029] 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.

[0030] 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.

[0031] In the description of this embodiment, the terms "upper," "lower," "left," and "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.

[0032] This invention provides an insertion wheel displacement detection device for detecting the position of the insertion wheel in a packaging machine. When the insertion wheel is slightly misaligned, it can be quickly detected so that timely adjustments can be made, thus ensuring the quality of the produced cigarette packs.

[0033] like Figures 1-5 As shown, in this embodiment, the insertion wheel movement detection device includes a mounting frame 1, a detection baffle 3, and an inductive proximity switch 2 mounted on the mounting frame 1. The mounting frame 1 is detachably connected to the fixed bushing 200 of the packaging machine. The detection baffle 3 includes a connecting part 31 and a protrusion 32 connected to each other. The connecting part 31 is detachably connected to the insertion wheel 100. In the axial direction of the insertion wheel 100, the projection of the protrusion 32 is located inside the insertion wheel 100, and the projection of the protrusion 32 is located outside the insertion wheel 100. After the insertion wheel 100 completes one working cycle, the inductive proximity switch 2 can detect whether the protrusion 32 is located in a preset position. Understandably, during the operation of the insertion wheel 100, after the insertion wheel 100 completes one working cycle, the inductive proximity switch 2 can detect whether the protrusion 32 is in a preset position. When the protrusion 32 is detected to be in the preset position, it indicates that the insertion wheel 100 is moving normally and there is no misalignment. When the inductive proximity switch 2 does not detect that the protrusion 32 is in the preset position, it indicates that the insertion wheel 100 has misaligned. The inductive proximity switch 2 can quickly detect the misalignment of the insertion wheel 100. Even if the insertion wheel 100 is slightly misaligned, it can be quickly detected so as to make timely adjustments and ensure the quality of the produced cigarette packs.

[0034] Furthermore, it can be inferred that the insertion wheel movement detection device in this embodiment can detect the movement of the insertion wheel 100, quickly identify slight movement of the insertion wheel 100, directly avoid excessive movement of the insertion wheel 100, and thus avoid situations such as cigarette pack blockage and equipment damage caused by excessive movement of the insertion wheel 100.

[0035] It should be noted that when the insertion wheel 100 completes one working cycle, it means after the insertion wheel 100 completes one pushing action and retracts. The preset position refers to the position of the protrusion 32 when the insertion wheel 100 is in the initial state. The fixed bushing 200 is an existing structure in the packaging machine and does not move with the insertion wheel 100, remaining in a relatively stationary state to ensure the stability of the inductive proximity switch 2.

[0036] In this embodiment, the detection baffle 3 is equivalent to the sensing element, and the detection baffle 3 is made of ordinary low-carbon steel, that is, both the connecting part 31 and the protrusion 32 are made of ordinary low-carbon steel. To facilitate production and improve the stability of the connecting part 31 and the protrusion 32, they can be integrally formed. The specific specifications of the inductive proximity switch 2 can be determined according to actual usage requirements; as long as the actual usage requirements are met, this embodiment does not impose specific limitations.

[0037] Furthermore, the insertion wheel movement detection device also includes a stop module. The inductive proximity switch 2 is communicatively connected to the stop module, which can send a stop signal to the stop module. The stop module can then control the limit switch of the packaging machine. It is understood that by setting the stop module, when the insertion wheel 100 completes one working cycle and the inductive proximity switch 2 does not detect the protrusion 32 at the preset position (i.e., the insertion wheel 100 has moved), the inductive proximity switch 2 sends a stop signal to the stop module. Upon receiving the stop signal, the stop module can control the limit switch of the packaging machine to stop the machine's operation and prevent damage. In this embodiment, both the stop module and the limit switch are existing structures, and will not be described in detail here. Their specific types can be determined according to actual usage requirements, and this embodiment does not impose specific limitations.

[0038] In this embodiment, the insertion wheel 100 can be driven by the drive shaft of a motor. The drive shaft has 20 drive teeth, and each drive tooth skips a movement of 18°. If the insertion wheel 100 moves and, after completing one working cycle, the protrusion 32 is not detected at the preset position, and the angle from the preset position is 18°, the inductive proximity switch 2 sends a stop signal to the stop module. Therefore, the detection range of the inductive proximity switch 2 cannot exceed 18°. Of course, in other embodiments, the insertion wheel 100 can also be driven by the drive shaft of other types of motors, and the detection range of the inductive proximity switch 2 can be determined according to actual usage requirements. This embodiment does not impose specific limitations.

[0039] Furthermore, such as Figures 2-4As shown, the mounting bracket 1 includes a first bracket 11, a second bracket 12 and a first fixing member. The inductive proximity switch 2 is mounted on the first bracket 11. The first bracket 11 and the second bracket 12 are both provided with first mounting holes 13. The first fixing member can pass through and be fixed to the first mounting holes 13 of the first bracket 11 and the first mounting holes 13 of the second bracket 12, so as to realize the detachable connection of the first bracket 11 and the second bracket 12. It is understood that by setting the first bracket 11, the second bracket 12, and the first fixing member, the detachable connection between the mounting bracket 1 and the fixed bushing 200 can be easily achieved. When the mounting bracket 1 needs to be installed, both the first bracket 11 and the second bracket 12 are located on the side of the fixed bushing 200. After aligning the first bracket 11 and the second bracket 12, the first fixing member passes through and is fixed in the first mounting hole 13 of the first bracket 11 and the first mounting hole 13 of the second bracket 12. At this time, the first bracket 11 and the second fixing member can be fixed on the fixed bushing 200. When the mounting bracket 1 needs to be disassembled, the first fixing member is driven out of the first mounting hole 13 of the first bracket 11 and the first mounting hole 13 of the second bracket 12 to achieve the disassembly of the first bracket 11 and the second bracket 12, which is convenient to operate. In this embodiment, the first fixing member can be a bolt, and the first mounting hole 13 can be a threaded hole, with the two connected by threads.

[0040] In this embodiment, in order to improve the stability of the mounting bracket 1, both the first bracket 11 and the second bracket 12 are arc-shaped, which facilitates the first bracket 11 and the second bracket 12 to fit into the fixed bushing 200, thereby improving the stability when it is fixed.

[0041] Furthermore, the first bracket 11 has a mounting portion 111 at the end away from the second bracket 12, and a second mounting hole 1111 is provided on the mounting portion 111. The inductive proximity switch 2 is mounted in the second mounting hole 1111. It can be understood that by providing the mounting portion 111 and the second mounting hole 1111 located in the mounting portion 111, it is convenient to install the inductive proximity switch.

[0042] For example, two first fixing members are provided. Both the first bracket 11 and the second bracket 12 are provided with two first mounting holes 13. The two first mounting holes 13 of the first bracket 11 are symmetrically arranged on the first bracket 11, and the two first mounting holes 13 of the second bracket 12 are symmetrically arranged on the second bracket 12. One first fixing member can pass through and be fixed to one of the first mounting holes 13 of the first bracket 11 and one of the first mounting holes 13 of the second bracket 12. The other first fixing member can pass through and be fixed to the other first mounting hole 13 of the first bracket 11 and the other first mounting hole 13 of the second bracket 12. It can be understood that by providing two first fixing members that cooperate with the two first mounting holes 1111 on the first bracket 11 and the two second mounting holes 1111 on the second bracket 12 to fix the first bracket 11 and the second bracket 12, the stability of the first bracket 11 and the second bracket 12 is improved.

[0043] like Figures 3-4 As shown, the two first mounting holes 13 of the first bracket 11 and the two first mounting holes 13 of the second bracket 12 are symmetrically arranged at the positions where the first bracket 11 and the second bracket 12 are connected to each other. This not only does not affect the installation of the first bracket 11 and the second bracket 12 on the fixed bushing 200, but also further improves the stability of the first bracket 11 and the second bracket 12 on the fixed bushing 200, thereby improving the stability of the inductive proximity switch 2.

[0044] Furthermore, such as Figure 5 As shown, the insertion wheel positioning detection device also includes a second fixing member. The connecting part 31 has a third mounting hole 311. The second fixing member can pass through and be fixed to the third mounting hole 311 and the insertion wheel 100, so as to detachably connect the connecting part 31 to the insertion wheel 100. Specifically, the third mounting hole 311 is a through hole, the second fixing member is a bolt, and the insertion wheel 100 is provided with a threaded hole that matches the second fixing member. It can be understood that by setting the second fixing member and the third mounting hole 311 to cooperate with the threaded hole of the insertion wheel 100, the connecting part 31 is detachably connected to the insertion wheel 100. In other words, the detection baffle 3 is detachably connected to the insertion wheel 100.

[0045] Furthermore, the third mounting hole 311 is an elongated hole. Specifically, the third mounting hole 311 is similar to an ellipse. By setting the third mounting hole 311 to be similar to an ellipse, the second fastener can move within the third mounting hole 311, which facilitates the installation of the second fastener.

[0046] It is conceivable that the connecting part 31 can also be detachably connected to the drive shaft of the motor used to drive the insertion wheel 100. The drive shaft of the motor passes through the fixed shaft sleeve 200 of the motor. The third mounting hole 311 is equivalent to providing a space for the second fixing member to pass through so that the connecting part 31 can be connected to the drive shaft. The drive shaft is provided with a threaded hole.

[0047] Furthermore, such as Figure 5 As shown, a groove 312 is provided at the end of the connecting part 31 away from the protrusion 32. It can be understood that by providing the groove 312, it is easier for the operator to hold the connecting part 31 for installation when installing the detection baffle 3. Furthermore, providing the groove 312 increases the rigidity of the connecting part 31, improves its stability, and thus ensures the stability of the protrusion 32, which is more conducive to improving the position detection accuracy of the inductive proximity switch 2 for the protrusion 32.

[0048] Furthermore, the edges of both the connecting portion 31 and the protrusion 32 are rounded. It is understood that by providing rounded edges on the connecting portion 31 and the protrusion 32, the risk of injury to the operator's hands is reduced when installing or removing the detection baffle 3, making installation easier.

[0049] This embodiment also provides a packaging machine, including the above-mentioned insertion wheel displacement detection device, so as to detect whether the insertion wheel 100 has shifted, thereby ensuring the quality of the cigarette pack.

[0050] 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.
