Description

Auxiliary box-drawing device for cigarette box

Technical Field

The utility model relates to a tobacco industry equipment field, the supplementary case device of drawing of smoke box promptly.

Background

In the prior art, a box dividing machine in the tobacco industry is important equipment on a cigarette sorting line, is widely applied to tobacco enterprises, and mainly adopts the following three box dividing machines: (1) laser formula drawing box machine. The laser element is used for emitting laser to automatically dissolve the sealing adhesive tapes on the two sides of the cigarette carton. (2) A full-automatic box opening (dividing) machine. (3) And a third-generation case unpacking machine. The laser type box dividing machine detects the size of the box body through a sensor, and commands a laser to ablate adhesive tapes on two sides of the adhesive tape box body through a control system, so that the adhesive tapes are cut off at the ablated part. Meanwhile, in order to ensure that the scratches continuously enable subsequent unpacking to be reliable, a mechanical auxiliary cutter is arranged, so that the unpacking machine can adapt to cigarette boxes sealed by deformed and multi-layer adhesive tapes and adhesive tapes made of different materials. Cigarette case letter sorting equipment belongs to the industrial standard production, and in the in-service use process, because the cigarette kind is many, the cigarette case material is different, has some problems in the actual motion. At present, a conveyor of a box drawing machine is in butt joint with a front assembly line and a rear assembly line, a cigarette box is automatically input and output, the cigarette box is sealed by a polyvinyl chloride transparent adhesive tape, and the height information of the cigarette box is fed back to the data deviation of a box drawing blade, so that the situation that the blade draws a cigarette box paper shell and stops an alarm to equipment is caused, or the blade damages cigarettes in the cigarette box and the like, and great economic loss is caused.

In the sorting work, the articles with cigarette damage caused by the box dividing machine are all specified to be partial cigarette boxes which are difficult to divide. To the difficult case of drawing of part (like secondary recovery smoke box and sticky tape thick smoke box etc.), because smoke box recovery back reutilization, partial smoke box form is not regular enough, and the data of drawing the punch-out equipment appear the deviation in the information feedback of height and width to equipment can be reported to the police and shut down when can lead to the blade to draw the smoke box paper case, the blade leads to the cigarette damage in going deep into the smoke box and leads to the fact economic loss.

Basic principle

The smoke box auxiliary box-dividing device mainly comprises three parts, a control part, a detection part and an execution part. The distance between the detector and the smoke box 8 is detected by an ultrasonic distance sensor of the detection part and is transmitted to the control part; the control part carries out a series of calculations to calculate the distance between the smoke box 8 and the cutter head 9 and the number, the speed and the direction of high-speed pulses required to be sent to the stepping motor; the cutting head 9 is then brought to the specified position by the linear module 4 of the implement part, ready for unpacking.

Detecting part

The detection part is a main component of the smoke box auxiliary box dividing device, and three high-precision ultrasonic distance sensors (a height measuring sensor 1, a left width measuring sensor 2 and a right width measuring sensor 3) are used. The ultrasonic sensor is a sensor developed by utilizing the characteristics of ultrasonic waves.

In practice, the detection section is positioned about 50cm in front of the actuator, taking into account the speed of movement of the smoke box 8 and the speed of movement of the actuator, leaving sufficient time for the actuator to move the cutter head 9 to the desired position.

Three ultrasonic sensor installs respectively at the top, the left side and the right side, and top ultrasonic sensor detects the height of smoke box, confirms tool bit 9 upper and lower position. The left ultrasonic sensor detects the position of the left cutter head 9 for opening the box through calculation by a programmable controller PLC of a control part. The right ultrasonic sensor determines the left and right positions of the right cutter head 9 for opening the box by calculation as in the left side.

In the aspect of data transmission detection of the sensor, an RS485 communication mode is used, so that the sensor is relatively stable and the transmission speed is relatively high. The PLC is used for reading the ultrasonic related data without a protocol communication instruction, and the three sensors have to set different addresses, so that the PLC can read the data. According to the characteristics of RS485 communication, the data of the three sensors cannot be read simultaneously, and finally, the data are read once for 100ms and stored.

Control section

The control part mainly comprises a Programmable Logic Controller (PLC). On one hand, the distance data of the detection part is received and then calculated, and on the other hand, the control execution part executes the unpacking. The programmable logic controller PLC uses the RS command to store the received distance signal in a register. Then, the distance and direction in which the cutter head 9 should move are calculated based on the set position at which the ultrasonic sensor is mounted and the position of the cutter head 9. The distance from the sensor 1 for measuring the height at the top to the smoke box 8 is stored in a Programmable Logic Controller (PLC) register, then the height of the smoke box is calculated according to the distance from the bottom of the smoke box 8 to the sensor, and then the height of the smoke box is divided by two to obtain the height of the cutter head 9 relative to the bottom of the smoke box. The programmable logic controller PLC reads the distance from the sensor to the smoke box and stores the distance into a register, and then the distance of the left-right movement of the cutter head 9 is determined according to the positions of the sensor and the cutter head 9. The control section ensures stable operation of the execution section.

Execution section

The execution part consists of four sets of linear modules 4 (or called sliding tables, which convert the rotary motion of a servo motor into linear motion) and two sets of box-dividing motors 5. The four sets of linear modules determine the box opening positions, wherein the left sets and the right sets are provided. The two sets of straight line modules 4 on the left side are combined together to form an X, Y shaft, the position can be accurately positioned according to the position sent by a Programmable Logic Controller (PLC), and the two sets on the right side and the two sets on the left side are executed in the same way. After the equipment is electrified, the linear module 4 needs to return to the zero point, and a parameter point of a position is accurately determined, so that the subsequent positioning is facilitated. It is also necessary to set a limit to prevent the motor from damaging the linear module 4. In addition, a box-cutting motor 5 (direct current motor) which drives the cutter head 9 to rotate rotates when the cigarette box needs to be cut, and does not rotate at other times.

The above description is only exemplary of the present invention, and the various illustrations do not limit the essence of the present invention.
