Description

Technical Field

[0001] The invention belongs to the technical field of detection equipment, and in particular relates to an inductive crease detection device for a hard box packaging of cigarettes. Background Art

[0002] Implementing the creasing process on cigarette hard box packaging, that is, on the printed cardboard or plate cardboard, effectively controls the deformation or breakage of the cardboard, creates the ability to fold and fold again, and makes it have the same performance as a "hinge". Good quality creases are used on high-speed packaging machines for smooth packaging, and the appearance is flat and full after forming, and the folding corners are straight and upright. Therefore, the quality and performance of the creases ultimately determine the forming effect of cigarette packaging and the normal performance of the packaging machine's production capacity. On high-speed automatic packaging lines, unqualified paper boxes often appear, which increases the scrap rate. The main factor causing the above phenomenon is the inappropriate crease depth of the cardboard after creasing.

[0003] Therefore, when the packaging paper of the hard box enters the factory, the depth of the crease will be tested to see if it meets the standard. At present, the crease detection is generally done by experienced inspectors visually and touching, and comparing with the standard crease depth card to see if it meets the standard. Manual inspection has low work efficiency, and each person has different standards, resulting in large errors. Summary of the invention

[0055] The method of use of the present invention is as follows:

[0056] The inductive crease detection device for cigarette hard-box packaging is used to place the cigarette hard-packing paper 29 to be detected in the groove 4 of the conveyor belt 3 manually or mechanically. The cigarette hard-packing paper 29 to be detected is placed in the correct position by positioning the positioning edge. The central controller 22 controls the intermittent rotation of the stepper motor 1. The second driving wheel 703 rotates in the clockwise direction through the drive of the stepper motor 1, so that the conveyor belt 3 moves to the right at a certain frequency, thereby driving the second driven wheel 704 to rotate in the clockwise direction. The second driven wheel 704 also causes the first cylindrical gear 11 to rotate in the clockwise direction. The first cylindrical gear 11 and the second cylindrical gear 1 2 is meshed and connected, so that the second cylindrical gear 12 rotates in the counterclockwise direction, so that the first driving wheel 701 rotates in the counterclockwise direction, so that the conveyor belt 8 rotates in the counterclockwise direction, driving the first driven wheel 702 in the counterclockwise direction, so that the fan gear 9 rotates in the counterclockwise direction. At this time, when the fan gear 9 rotates one circle, the distance between the two grooves 4 of the conveyor belt 3 is equal to half of the distance between the third positioning edges 503 of the two grooves 4 in the absence of external force. When the fan gear 9 rotates to the gearless part and the conveyor belt 3 advances to half of the distance between the third positioning edges 503 of the two grooves 4, the fan gear 9 rotates to the gearless part and the conveyor belt 3 advances to half of the distance between the third positioning edges 503 of the two grooves 4, The first tooth of the gear 9 meshes with the first tooth of the rack 13 from bottom to top and starts to run, so that the detector 14 starts to move downward. When the groove 4 on the conveyor belt 3 is just below the detector 14, it is considered to have reached the fixed point. At this time, the lower surface of the detector 14 fits with the upper surface of the cigarette box hard packaging paper 29 to be detected, so that the fold strip 30 on the cigarette box hard packaging paper 29 to be detected fits with the fold groove 16 on the detector 14. At this time, the central controller 22 controls the stepper motor 1 to stop rotating and the conveyor belt 3 stops moving. After the detector 14 completes the detection, if the detection result is qualified, the detector 14 transmits a qualified signal to the central controller 22, and the central controller 22 controls the stepper motor 1 to stop rotating. The motor 1 drives the conveyor belt 3 to continue to move forward, and the qualified cigarette box hard packaging paper 29 moves forward to enter the next process. If the test result is unqualified, the detector 14 sends an unqualified signal to the central controller 22. The central controller 22 controls the cylinder 20, so that the cylinder 20 pushes the push rod 21 to move outward. The push rod 21 pushes the unqualified cigarette box hard packaging paper 29 through the channel 6, so that the unqualified cigarette box hard packaging paper 29 moves outward and falls into the collection box 25 through the inclined plate 24. When the top end of the push rod 21 reaches the outer edge of the conveyor belt 3, the cylinder 20 retracts the push rod 21 and returns to the starting point. The conveyor belt 3 continues to move forward and continues to detect the next cigarette box hard packaging paper 29.

[0057] There are three detection situations:

[0058] The first detection situation: when the groove 4 reaches the fixed point, if the crease strip 30 on the cigarette box hard packaging paper 29 to be detected does not fit the crease groove 16 on the detector 14, it means that the overall size of the cigarette box hard packaging paper 29 is unqualified, the crease strip 30 on the cigarette box hard packaging paper 29 cannot touch the sensor 17 in the crease groove 16, and the central controller 22 cannot receive the signal of the sensor 17, and it is determined that the cigarette box hard packaging paper 29 being detected is unqualified;

[0059] The second situation: when the groove 4 reaches the fixed point, if the crease strip 30 on the cigarette box hard packaging paper 29 to be tested fits the crease groove 16 on the detector 14, but the crease depth is not enough, the three sensors 17 at the two ends and the middle position of the crease groove 16 cannot be touched, or one or two sensors 17 are touched, the central controller 22 cannot receive the signals sent by the three sensors 17 at the same time, and determines that the cigarette box hard packaging paper 29 being tested is unqualified;

[0060] The third situation: when the groove 4 reaches the fixed point, if the crease strip 30 on the cigarette box hard packaging paper 29 to be tested fits with the crease groove 16 on the detector 14, the crease strip 30 can touch the three sensors 17 at the same time, and the central controller 22 receives the signals sent by the three sensors 17 at the same time, and determines that the cigarette box hard packaging paper 29 being tested is qualified.

[0061] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
