Description

Technical Field

[0001] The invention belongs to the technical field of cigarette production equipment, and in particular relates to a photoelectric small-box cigarette package flip cover defect detection device and a detection method. Background Art

[0002] During the production process of hard-lid cigarettes, the front edge of the small box label paper flip cover has a cover tongue design. Under normal conditions, the cover tongue should be folded back into the inside of the flip cover to complete the wrapping and forming of the aluminum foil cigarette package.

[0003] During the process design, the cover tongue has two modes: glued and un-glueed. In the un-glueed design, the cover tongue will be lifted up to a straight state due to the elasticity of the label paper material. When the lifted state reaches a certain limit, when the flip cover is folded, the cover tongue is blocked by the aluminum foil cigarette pack and becomes straight under the action of the folder, and is inserted into the inner side of the label paper on the lower half of the front of the hard box cover cigarette, resulting in a quality defect that the flip cover cannot be opened after forming. All current roll packaging equipment does not involve detection of this quality defect. Summary of the invention

[0004] The purpose of the present invention is to provide a photoelectric small box cigarette package flip cover defect detection device and detection method, so as to solve the problem that when the hard box cover cigarettes are formed, the cover tongue fails to complete the normal folding, but instead inserts into the inner side of the lower half of the front side of the trademark paper, resulting in the small box flip cover being unable to open, and without detection and removal, it flows into the finished product and then enters the market circulation.

[0005] To achieve the above objectives, this application is implemented through the following technical solutions:

[0006] A photoelectric small-box cigarette cover defect detection device comprises a support rail, on which the hard-box cover cigarette moves in a horizontal state, and a pressing plate is arranged above the support rail, the pressing plate is mounted on a pressing plate mounting bracket, and the pressing plate moves up and down along the pressing plate mounting bracket through a pressure driving device;

[0007] A long slot is arranged on one side of the pressing plate, and a detector is fixed at the long slot. The detector is connected to a controller by electrical signals, and the controller is connected to a rejecting mechanism by electrical signals.

[0008] Furthermore, the detection head of the detector corresponds to the flip cover opening of the hard-cover cigarette pack.

[0009] Further, the detector is one of mechanical contact, photoelectric, microwave or laser distance measuring instruments. Further, the pressing plate applies appropriate pressure to the hard box cover cigarette and keeps the shape of the hard box cover cigarette stable.

[0010] Further, the pressing plate includes a rectangular pressing plate body, and a long slot is provided on one side of the pressing plate body, and the long slot corresponds to the flip opening of the hard box cover cigarette passing through.

[0011] Further, the pressing plate driving device includes a pressing plate driving controller and a display screen. The display screen is electrically connected to the pressing plate driving controller, and the pressing plate driving controller is electrically connected to the controller.

[0012] Further, an alarm device is further included, and the alarm device is electrically connected to the controller.

[0013] An optoelectronic detection method for the flip defects of small box cigarette packs uses the optoelectronic detection device for the flip defects of small box cigarette packs as described in any one of the above, and includes the following steps:

[0014] S1. Determine the pressure data when the hard box cover cigarette to be detected is in a lying state and the cigarette box shape is stable, and store it in the pressing plate driving controller;

[0015] S2. The hard box cover cigarette to be detected moves to the lower part of the pressing plate in a lying state through the support guide rail, and the pressure driving device drives the pressing plate to press down to the pressure data determined in step S1;

[0016] S3. The detector respectively detects the relative heights on both sides of the flip opening of the hard box cover cigarette, and transmits the detected data to the controller;

[0017] S4. The controller makes a judgment according to the detection data. If the height of the flip side is greater than the height of the lower part of the cigarette box and the height difference is within the set range, it is judged that the hard box cover cigarette is qualified, otherwise, go to step S5;

[0018] S5. If the height of the flip side is less than the height of the lower part of the cigarette box, or the height of the flip side is greater than the height of the lower part of the cigarette box and the height difference is greater than the maximum value of the set range, it is determined that the hard box cover cigarette is unqualified, and the controller transmits the unqualified signal to the rejection mechanism.

[0019] Further, the controller transmits the unqualified signal to the alarm device.

[0020] The beneficial effects of the present invention are:

[0021] Through the principle of the defects generated by the hard box flip cigarette, this technical solution realizes the detection needs by using the change of the height difference between the two sides of the flip opening of the defective cigarette and the normal cigarette. When the defective cigarette appears, the existence of the defective cigarette is found by detecting the change of the height difference, and the operator is notified to take out the defective cigarette by means of stopping the machine and displaying at the same time, or setting synchronous rejection in the program to remove the defective cigarette from the normal circulation channel, so as to ensure the quality of the products in the finished products.

[0025] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, and cannot be construed as a limitation to the technical solution of the present invention.

[0026] As Figure 1 shown, the present application provides a photoelectric small box cigarette pack flip cover defect detection device, including a support guide rail 1. The support guide rail of the present application is a prior art, and a rotating roller or a conveyor belt can be arranged between the two parallel guide rails of the support guide rail to ensure that the hard box cover cigarette 4 moves horizontally on the support guide rail 1. The specific structure of the support guide rail is determined according to the actual situation of the production enterprise.

[0027] The hard box cover cigarette 4 moves on the support guide rail in a lying state. The flip cover of the hard box cover cigarette can be upward or downward. Preferably, it is upward, which is convenient for adding a detection device. If it is downward, a position for installing the detection device needs to be reserved below the detection position, and it is ensured that the opening direction of the flip cover is in a horizontal state.

[0028] A pressure plate 2 is arranged above the support guide rail 1. The pressure plate 2 of the present application includes a rectangular pressure plate body. In order to prevent damage to the outer plastic packaging of the hard box cover cigarette, a stainless steel plate is usually used. If a plastic plate is used, there are problems such as increased friction and easy generation of static electricity. A long slot 21 is arranged on one side of the pressure plate body. In the present application, the number of long slots 21 can be one or more. If there are more than one, a detector 3 is installed at each long slot to improve the detection efficiency. In the present application, the length of the long slot is less than the width of the hard box cover cigarette to be detected, so as to realize the balanced pressure of the pressure plate on the hard box cover cigarette, and avoid the situation that there is pressure on the box body part but no pressure on the flip cover 41 part, resulting in an artificial position difference between the flip cover 41 and the box body and affecting the detection effect.

[0029] The pressure plate 2 is installed on the pressure plate installation bracket, and the pressure plate installation bracket is installed on the support guide rail bracket or the ground on one side of the support guide rail. The pressure plate moves up and down along the pressure plate installation bracket through a pressure driving device. The pressure driving device can be a hydraulic device or other devices to provide the pressure of the pressure plate on the hard box cover cigarette.

[0030] A long slot 21 is provided on one side of the pressing plate 2, and the detector 3 is fixed at the long slot 21. The detector 3 is electrically connected to the controller, and the controller is electrically connected to the rejection mechanism.

[0031] In this application, the detection head of the detector 3 corresponds to the flip opening of the hard box cover cigarette. There are various specific choices for the detector in this application. It can be a mechanical contact probe, combined with sensitive elements such as capacitance and inductance to determine the height difference; it can also be an optoelectronic, microwave or laser ranging tool for measurement.

[0032] The pressing plate driving device of this application includes a pressing plate driving controller and a display screen. The display screen is electrically connected to the pressing plate driving controller, and the pressing plate driving controller is electrically connected to the controller. The display screen is used to display the pressure value of the pressing plate, and the driving controller is used to store the pressure range numerical information of the hard box cover cigarette.

[0033] This application also provides an optoelectronic detection method for the flip defects of small box cigarette packs. Using the optoelectronic detection device for the flip defects of small box cigarette packs according to any one of the above, it includes the following steps:

[0034] S1. Determine the pressure data of the hard box cover cigarette to be detected in the lying state and keep the shape of the cigarette box stable, and store it in the pressing plate driving controller. Because the bearing capacities of cigarette boxes of different models are different, the pressure data for keeping the shape of each model of cigarette box stable needs to be determined.

[0035] S2. The hard box cover cigarette to be detected moves to the lower part of the pressing plate in the lying state through the support guide rail. The pressure driving device drives the pressing plate to press down to the pressure data determined in step S1, and this pressure data is also displayed on the display screen for the operator to observe. And the detection requirements of this application protect the stability of the pressure value, there is no pressure range value, but a determined value.

[0036] S3. The detector respectively detects the relative heights on both sides of the flip opening of the hard box cover cigarette, and transmits the detected data to the controller. There is a height difference between the flip side height and the lower part height of the cigarette box in the controller. The flip side height of a normal hard box cover cigarette should be greater than or equal to the height of the lower part of the cigarette box, while the flip height of a defective cigarette is less than the height of the lower part of the cigarette box.

[0037] S4. The controller makes a judgment based on the detection data. If the flip side height is greater than or equal to the height of the lower part of the cigarette box and the height difference is within the set range, it is judged that the hard box cover cigarette is qualified, otherwise it enters step S5.

[0038] S5. If the flip side height is less than the height of the lower part of the cigarette box, or the flip side height is greater than the height of the lower part of the cigarette box and the height difference is greater than the maximum value of the set range, it is determined that the hard box cover cigarette is unqualified. The controller transmits the unqualified signal to the rejection mechanism, and the rejection mechanism rejects it at the set position, or the unqualified cigarette pack can also be removed from the support guide rail manually.

[0039] In this application, the controller transmits a non-conforming signal to the alarm device to remind the operator of the occurrence of non-conforming cigarette packs, so as to facilitate the operator to manually remove them or monitor whether the rejection mechanism rejects the non-conforming cigarette packs.

[0040] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
