[0002] Cellophane wrapping is a type of transparent paper packaging that covers the outside of a carton. Its purpose is to enhance moisture resistance, heat preservation, and shelf-life, while also improving the product's appearance. To facilitate tearing, a pull string is usually provided on the cellophane wrapping. A pull string detector is a device used to check whether the pull string on the cellophane wrapping is in the correct position. It can prevent missing or misaligned pull strings, thus preventing cellophane packaging with substandard pull string positions from entering the market.

[0003] As BV wrapping machines age, the old-style pull-string detectors on these machines have become obsolete. The market typically replaces them with newer models. However, due to differences in size and installation location between the old and new pull-string detectors, the new detectors cannot be directly mounted on the testing base, resulting in low compatibility. Furthermore, the old-style detectors are usually fixed to the testing base with screws, requiring repeated disassembly and disassembly when testing cellophane with different pull-string positions, which is time-consuming and laborious.

Detailed Implementation

[0029] 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.

[0030] 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.

[0031] 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.

[0032] In the description of this embodiment, the terms "upper," "lower," "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.

[0033] Referring to Figures 1 to 5, this embodiment proposes a wire pulling detection device, including a support member 1 and a detection element 2. The support member 1 is used to support the detection element 2, and the detection element 2 is used to detect the position of the wire pulling on the workpiece to be tested. The support member 1 includes a connecting seat 11, a pad 12 and a bracket 13 connected in sequence. The connecting seat 11, the pad 12 and the bracket 13 form a receiving groove 3 for receiving the detection element 2. The detection element 2 is movably disposed on the bracket 13 and a detection gap 4 is provided between it and the connecting seat 11 for accommodating the workpiece to be tested. The detection component 2 is connected to the bracket 13, the bracket 13 is connected to the pad 12, and the pad 12 is connected to the connecting seat 11 to realize the installation of the detection component 2 and the detection base. The detection component 2 is partially placed in the receiving groove 3 formed by the connecting seat 11, the pad 12 and the bracket 13, which improves the installation compatibility of the detection component 2. The detection component 2 can move on the bracket 13 to change the detection range of the detection component 2, thereby enabling the detection of workpieces with different pull wire positions. The detection component 2 and the bracket 13 are detachably connected, and different models and specifications of the detection component 2 can be replaced according to work requirements, which improves the detection flexibility.

[0034] Before the wire pulling detection device begins testing, the position of the detection element 2 on the support 13 is adjusted so that its detection range is aligned with the correct wire position on the workpiece to be tested. This zeroing of the detection element 2 ensures the accuracy of subsequent test results. Specifically, when the detection element 2 is zeroed, its detection range is aligned with the correct wire position on the workpiece, and the indicator light on the detection element 2 is lit. When the detection element 2 is not zeroed, its detection range is not aligned with the correct wire position on the workpiece, and the indicator light on the detection element 2 is off, prompting the operator to adjust it promptly. During testing, the workpiece enters the detection gap 4, and the detection element 2 detects it. If the detection element 2 detects no wire on the workpiece, it indicates that there is no wire within its detection range, meaning the wire is not in the correct wire position on the workpiece, indicating that the wire position on the workpiece is inaccurate or that there is no wire on the workpiece.

[0035] The testing component 2 can be an LRD500C wire detector, which has high-precision testing capabilities and can accurately locate and inspect the wires on the workpiece under test, reducing the risk of missing or incorrectly positioned wires. Correspondingly, the pad 12 can be a cuboid with a length of 40.1 mm, a width of 34 mm, and a height of 20.5 mm, so that the testing gap 4 between the testing component 2 and the connecting seat 11 is just enough to accommodate the workpiece under test.

[0036] The support component 1 also includes a movable component 14. A guide hole 131 is provided on the bracket 13. The movable component 14 passes through the guide hole 131 and is connected to the detection component 2. The movable component 14 can move along the extension direction of the guide hole 131 and be fixed at any position in the guide hole 131, thereby driving the movement and fixation of the detection component 2. The guide hole 131 provides guidance for the movement of the detection component 2, preventing misalignment during movement that would prevent the subsequent detection range of the detection component 2 from being aligned with the correct wire position on the workpiece. Furthermore, the movement of the detection component 2 via the movable component 14 improves adjustment flexibility and accuracy, and allows the detection component 2 to be fixed on the bracket 13 for subsequent testing.

[0037] Furthermore, at least two guide holes 131 are provided, and the at least two guide holes 131 extend in the same direction. The presence of at least two guide holes 131 extending in the same direction provides further assurance for the movement stability of the detection element 2, offering more stable support and preventing the risk of the moving element 14 rotating within the guide holes 131 during the movement of the detection element 2, thus improving stability. In this embodiment, two guide holes 131 are provided, and the two guide holes 131 are spaced apart along a direction perpendicular to the extension direction. In other embodiments, the at least two guide holes 131 may also be spaced apart along the extension direction, as long as it ensures that the moving element 14 can move within the guide holes 131 along its extension direction.

[0038] Preferably, the detection element 2 and the movable element 14 are detachably connected, allowing the detection element 2 and movable element 14 to be separated and then replaced with different detection elements 2 and movable element 14, thereby improving detection flexibility. Specifically, the movable element 14 is threadedly connected to the detection element 2. The detection element 2 has a first connecting hole 21 with threads on its wall. The movable element 14 passes through the guide hole 131 and engages with the first connecting hole 21 to achieve the connection between the movable element 14 and the detection element 2. When the detection element 2 needs to be replaced, simply unscrew the movable element 14 to detach it from the detection element 2. The movable element 14 can be directly bolted, making operation convenient. It is understood that the position of the first connecting hole 21 is the same on different detection elements 2 to ensure that different detection elements 2 can be engaged with the movable element 14. In other embodiments, the movable element 14 and the detection element 2 can also be magnetically connected, which is not limited here.

[0039] Furthermore, the movable member 14 is provided with a shoulder 141. The shoulder 141 and the detection member 2 can respectively abut against the opposite sides of the bracket 13 to form an interactive clamping force on both sides of the bracket 13, thereby fixing the movable member 14 to the guide hole 131 and thus fixing the position of the detection member 2 on the bracket 13. Specifically, the movable member 14 can be a bolt, and the shoulder 141 can be a nut on the bolt. After the bolt passes through the guide hole 131, it is threadedly connected to the first connecting hole 21 and tightened. At this time, the nut and the detection member 2 abut against both sides of the bracket 13 and apply an interactive clamping force, thereby fixing the detection member 2 on the bracket 13. Of course, in other embodiments, when the movable member 14 and the detection member 2 are magnetically connected, the movable member 14 is provided with a shoulder 141. The movable member 14 passes through the guide hole 131 and is magnetically connected to the detection member 2. The shoulder 141 and the detection member 2 abut against both sides of the bracket 13 and apply an interactive clamping force, thereby fixing the detection member 2 on the bracket 13.

[0040] An adjustment knob 22 is provided on one end of the test piece 2 near the pad 12. A receiving groove 122 is recessed on the side of the pad 12 near the test piece 2. When the test piece 2 moves on the bracket 13, the adjustment knob 22 can be placed within the receiving groove 122. In other words, the receiving groove 122 provides clearance for the adjustment knob 22, preventing interference or even collision between the adjustment knob 22 and the pad 12 during movement, thus avoiding damage to the test piece 2. Furthermore, the receiving groove 122 can be a through groove, meaning it extends through both sides of the pad 12 near and away from the test piece 2. In this case, the receiving groove 122 can serve as an adjustment channel, allowing operators to adjust or calibrate the adjustment knob 22 using special tools. The through groove 122 also acts as a heat dissipation channel, helping to maintain the stable operating temperature of the test piece 2. Specifically, the dimensions of the receiving groove 122 can be 40.1 mm in length, 10 mm in width, and 14 mm in height.

[0041] Preferably, the support member 1 further includes a connector 15. The bracket 13 is provided with a second connecting hole 132, and the pad 12 is provided with a third connecting hole 121. The connector 15 passes through the second connecting hole 132 and the third connecting hole 121 in sequence to connect the bracket 13 and the pad 12. The connector 15 can be a bolt. The walls of the second connecting hole 132 and the third connecting hole 121 are both provided with threads, and the connector 15 is threadedly connected to both the second connecting hole 132 and the third connecting hole 121.

[0042] The connecting seat 11 is provided with a fourth connecting hole 111. The connecting member 15 can pass through the third connecting hole 121 and the fourth connecting hole 111 to connect the pad 12 and the connecting seat 11. Specifically, the connecting member 15 can be a bolt. The walls of the second connecting hole 132, the third connecting hole 121, and the fourth connecting hole 111 are all provided with threads. The connecting member 15 is sequentially threaded into the second connecting hole 132, the third connecting hole 121, and the fourth connecting hole 111 to sequentially connect the bracket 13, the pad 12, and the connecting seat 11. Preferably, there are four second connecting holes 132, the third connecting hole 121, and the fourth connecting hole 111 to ensure the connection strength between the bracket 13, the pad 12, and the connecting seat 11, thereby improving the connection stability. Of course, in other embodiments, the bracket 13, the pad 12, and the connecting seat 11 can also be fixed by welding.

[0043] Furthermore, an operating panel is provided on the side of the testing component 2 near the support 13. When the testing component 2 moves on the support 13, the operating panel remains exposed outside the support 13, ensuring that operators can operate the panel in real time to adjust the parameters of the testing component 2, thus improving operational flexibility. Specifically, the support 13 is a cuboid with a length of 140.1 mm, a width of 35.1 mm, and a height of 15.1 mm. The guide hole 131 has a length of 32 mm and a width of 5 mm.

[0044] In this embodiment, the workpiece to be tested is cellophane, which is used to package cigarette cartons. The pull tabs on the cellophane make it easy to tear the cellophane.

[0045] On the other hand, this embodiment also provides a production line, including a conveying device and the above-mentioned wire drawing detection device. The conveying device is used to transport the workpiece to be tested into the detection gap 4, which has high production efficiency.

[0046] Furthermore, as shown in Figure 6, the production line also includes a PLC controller. The PLC controller is connected to a host computer (HMI) via Ethernet. The HMI is used to monitor the PLC's operating status, modify control parameters, display alarm information, and record alarm information. The PLC controller is connected to remote I / O stations via a fieldbus. The I / O stations include input modules, output modules, button terminals, valve islands, frequency converters, etc. The signal from the detection element 2 is connected to the input module on the I / O station, and the output module controls the rejection signal for the cigarette cartons. It is understandable that rejecting cigarette cartons prevents the cellophane from being used to package cigarette cartons directly if the packaging line is incorrect, thus avoiding increased costs associated with errors.

[0047] During the actual testing, if the detection element 2 detects that the pull wire on the workpiece is in the correct position, the production line operates normally. If the detection element 2 detects that the pull wire is not in the correct position on the workpiece, it is considered that the pull wire signal is missing. The detection element 2 transmits this signal to the PLC controller, which then transmits the rejection information to the host computer HMI. The host computer HMI displays and records the number of rejected items and the rejection time. If two or fewer items are rejected consecutively, the production line continues production. If three or more items are rejected consecutively, the PLC controller commands the production line to stop and displays the reason for the stop on the host computer HMI.

[0048] 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.
