Description

A detection device for inner frame paper of a cigarette packaging machine

technical field

The utility model relates to a cigarette pack inner frame paper defect detection device of a cigarette packing machine, which comprises a logic controller, a color mark sensor and a synchronous sensor.

Background technique

ZB45 hard box and rigid strip packaging unit is an advanced high-speed cigarette packaging equipment imported from Italy G.D. It is reasonably designed and reliable. It is currently the main cigarette packaging equipment in my country's tobacco industry. The YB45 hard box packaging machine is the main part of the ZB45 hard box and hard strip packaging unit. It takes 20 cigarettes from the upstream machine (arranged in 7-6-7) as a "cigarette group", wraps the outside with aluminum foil, and the inner frame Paper and trademark paper are folded and glued to complete the packaging of cigarettes to form qualified hard box cigarette packs, and the cigarette packs are transported to the downstream machine.

The inner frame paper tray is installed on the mandrel, and is guided by a series of fixed paper feed rollers and floating paper feed rollers to form an inner frame paper tape, and then the inner frame paper tape is fed by the pressure roller and the fixed paper feed roller. Into the conveying and crease cutting box, after micro crease and cutting, the inner frame paper is sent to the inner frame paper forming mold box of the four-wheel first station by the suction rod. The original machine is equipped with a photoelectric switch at the second station of the four wheels, which is used to detect whether there is paper in the inner frame. The YB45 cigarette packaging machine has the following problems in the process of operation: 1. After the inner frame paper crease knife has been worn and passivated for a long time, the crease of the inner frame paper is not deep enough, and the inner frame paper is transported to the four-wheel mold box 2. The four-wheel mold box wears out after a long time of use, causing the inner frame paper to be stuck in the mold box unstable, and it will fly out of the mold box during high-speed operation. The mold box flew out. After investigation and analysis, during the packaging process of the inner frame paper from the second station of the fourth round to the fifth station of the fifth round (cigarette packs are completely wrapped with trademark paper), the YB45 cigarette packaging machine did not detect whether there is inner frame paper in the cigarette packs , there is a detection blind spot, which will cause quality defects in the cigarette package missing the inner frame paper.

Utility model content

The problem to be solved by the utility model is to provide an inner frame paper detection device which can automatically detect the lack of inner frame paper in cigarette packs of YB45 cigarette packaging machine and automatically reject the cigarette packs with inner frame paper missing.

In order to solve the above problems, the technical solution provided by the utility model is: including a logic controller, a color mark sensor and a synchronous sensor, the color mark sensor is installed at the position of the fourth station between the inner and outer semicircular frames of the five wheels , the synchronous sensor is installed on the inner upper folder support.

Described logic controller comprises power supply, input interface, output interface and control unit, described power supply adopts LM7805 three-terminal voltage regulator, described input interface adopts TLP521, described output interface uses JQX-115 type relay, all The above-mentioned control unit selects ATmega8 single-chip microcomputer.

Use the color difference between the inner frame paper and the aluminum foil paper to identify whether there is a lack of inner frame paper in the cigarette pack. The color mark sensor is based on the principle of photometric color mark and background color difference detection, and the reflection or absorption of the object on the light beam is compared with the surrounding materials. Realize the detection of different objects, red and green dual light sources, capable of detecting 30-level gray scale and low-contrast color scale, with high sensitivity, fast response, intelligent, non-contact measurement, adaptable to use and use in various harsh environments Advantages such as simplicity.

Detailed ways

The color mark sensor 6 is installed at the fourth station between the inner and outer semicircular frames of the five wheels, and detects the inner frame paper in the cigarette pack before the cigarette pack is completely wrapped by the trademark paper. The synchronous sensor 8 is an inductive proximity switch, installed On the inner upper folder support 5, the synchronous signal is obtained by detecting the mechanical action of the inner upper folder 4, which is also used as a shift pulse signal of the cigarette pack.

In Figures 1 and 3, the color mark sensor is installed between the five-wheel inner semicircle frame 1 and the outer semicircle frame 2 of the YB45 cigarette packaging machine, the fourth station 3 of the five-wheel, and the synchronization sensor 8 is installed on the inner upper folder support 5 .

The logic controller includes power supply, input and output interface and control unit. The source adopts LM7805 three-terminal voltage regulator, and the 24V DC power supply on the original machine is reduced to 5V as the power supply of the single-chip microcomputer. The input point uses TLP521 for 24V to 5V level conversion. The output point uses JQX-115 type (coil voltage 24V, contact capacity 12A) relay; the control unit selects ATmega8 single-chip microcomputer, and writes the logic control program in C language.

In Figures 1, 2, and 3, the synchronous sensor 8 detects the action of the inner upper folder 4, and outputs a synchronous pulse as a synchronous signal, which is also used as a displacement signal of the cigarette pack. Adjust the installation position of the synchronous sensor 8, when it is triggered by the inner upper folder 4 and the output changes from low level to high level (the rising edge of the synchronous pulse), the machine phase of the YB45 cigarette packaging machine is 290 degrees. The color mark sensor 6 detects the inner frame paper 7 in the cigarette pack 9 before the cigarette pack at the fourth station 3 of the fifth round is completely wrapped by the trademark paper. When there is the inner frame paper 7, it outputs a high level, and if there is no inner frame paper 7, it will output a high level. output low level.

As shown in Figure 4, when the color mark sensor 6 detects that the inner frame paper 7 of the cigarette package is missing at the rising edge of the synchronous pulse signal of the synchronous sensor 8, the logic controller sends out an alarm signal, and the buzzer alarms for 5 seconds. At the same time, the logic controller shifts the synchronous pulse to track the cigarette packs lacking the inner frame paper 7. When the cigarette packs arrive at the eight-wheel Q rejecting station, the logic controller outputs a rejecting signal, and the electromagnetic valve of the Q rejecting station acts to move the Cigarette packs are removed.

The detection and elimination of the device is accurate and reliable, and the entire detection and elimination process is automatically carried out during the operation of the YB45 cigarette packaging machine, which will not cause the shutdown of the packaging machine and will not affect production. The logic controller of the inner frame paper detection device of the YB45 cigarette packaging machine is installed in the electrical control cabinet of the cigarette packaging machine, without affecting the appearance of the packaging machine.
