Description

There are known devices for rejecting cigarettes on the basis of the formation of a neck when the cartridge is not filled with tobacco, made in the form of sensors equipped with a probe that is deflected by each moving cigarette and closes a relay circuit that turns off the drive of the stuffing machine.

In the proposed device, in order to improve the quality of rejection of cigarettes, removal of defects, signaling about types of rejects and turning off the drive of the stuffing machine, in the absence of cigarettes, three contact sensors are used, two of which, connected in parallel, control the packing and the presence of a neck in two different places of the sleeve. connected to kimi in series, serves to turn them on when there is another cigarette, and interacts with its mouthpiece, and the output circuit of the relay includes: a mechanism for removing defective cigarettes, a step suit A spruce lamp, which turns on the warning lamp after removing defective cigarettes over a set number, and a time switch, which includes the initial positioner, a photoelectric sensor connected to an electronic relay circuit, including a corresponding signal lamp, and another photoelectric sensor, reflected by reflected light from the cigarette mouthpiece, included in the circuit of another electronic relay, which turns on the corresponding signal lamp and turns off the drive of the ramming machine.

To remove defective cigarettes, a mechanism in the form of an electromagnet mixed with a hook interacting with a cigarette to be removed is used. For a more reliable response, contact sensors are included in the circuit of the grid of electronic tubes (relays).

According to the conclusion of 1 tobacco factory of the Georgian Economic Council, the prototype of the proposed device worked flawlessly.

No. 141087- 2 .Fig. 4 - installation of the actuator and the measuring sensor.

The line of rejection cigarettes consists of two measuring and one executive sensors. Each measuring sensor contains a non-moving contact / and a movable 2 fixed on the textolite sector 3, the latter can rotate around its axis at an angle of up to 45 ° and be held in one of the extreme positions by the tension of the spring 4. The tension of the spring can be adjusted by rotating the pin 5. At by lightly pressing the protruding part of the textolite sector, the latter rotates around its axis, and the contacts / and 2 open. The executive sensor has a contact pair 6, isolated from the metal case 7. At the end of the lower contact spring, a textolite roller 8 is loosely attached to the axis 8. When the roller is pressed lightly from the bottom, contact 6 closes. Screw 9 is used to adjust the gap between the contact and eliminate the oscillation of the contact spring when the stuffing machine vibrates. The measuring sensor L is positioned so that the protruding part of sector 3 touches approximately the middle part of the cigarette (2-3 mm at the end of the mouthpiece). The second measuring sensor Lp oprats on the tip of a cigarette stuffed with tobacco. The contacts of the sensors L and Yes are connected in parallel. With a tight packing and full filling of the sleeve with tobacco, the contacts of the sensors will open when the controlled cigarette rushes. If there is insufficient tobacco filling (soft tip) or voids near the mouthpiece (soft middle), the cigarettes under the force of the spring are pulled and the contacts will remain closed. Consistently with the contacts of the measuring sensors are included the contacts of the executive sensor Dz, which is mounted so that its roller slides along the tip of the mouthpiece of the cigarette. Each time the mouthpiece of a cigarette rushes under the roller of the executive sensor, its contacts are closed. In the case of simultaneous closing of the contacts of one of the measuring sensors (scrap), the whole circuit is closed.

The sensor circuit is included in the grid circuit of the lamp L1 (type 6Н8с), in the anodic circuit of which the relay Pi is connected (of the type of RKN). A negative voltage is applied to the grid of the lamp L1, which is removed from the divider and the locking lamp L1. When the contacts of the sensors are closed, a negative bias to the grid of the lamp L1 is not supplied, the lamp is unlocked, the relay P1 is activated, and its contacts turn on the actuator 10, which removes the defective cigarette from the conveyor.

As an actuator, a contactor electromagnet (type K-100) is used, in which the contact system is removed. A rod 0 3 lsh with a curved hook-shaped end is attached to the nodule bark. When the actuator triggers, the hook moves forward, grabs the defective cigarette and, under the action of the return spring, removes it from the conveyor. The signaling device of these warning lamps signals the normal operation of the ramming machine. Signal lamp SL1 - marriage, - indicates an excessive marriage output and the need to set up a ramming machine. Signal lamp SL2 - tobacco - signals an unnecessary exit of tobacco and emptying it: with paws. The lamp СЛЗ - sleeve - signals the disconnection of the sleeves (clogging of the cartridge case). The signal of an elevated reject rate is generated using an STI step detector and a time relay consisting of an L2 lamp (type 6H8s and an electromagnetic relay P2). The rotor of the step finder is moved one step at each dropping of the defective pa-pitos by the actuator as a result of the closing of the contacts, s, IPl. in the case of dropping the rounded number of defective cigarettes for the control time, set with the help of a time relay, the lamp SL1 is turned on, indicating the need for adjusting the mask. The time relay operates according to a relaxation scheme with deep negative feedback, due to which the time delay reaches 5-JO minutes. After the control time expires, relay P2 returns the rotor of the searcher to its initial position and proceeds to the next work cycle.

The photocell FE1 (type SUVZ), illuminated by the reflected beam of light from the heads of cigarettes, locks the lamp LZ (type 6N8S). When a pile of tobacco approaches, the reflected beam of light is weakened several times, the LZ lamp is unlocked, and the relay is triggered. The contacts of this 1RZ relay include the SL2 lamp (disorder of the tobacco supply system).

Lamp L4 (type 6Н8С) is locked with an FE2 photocell (type С8В-3) illuminated by a reflected beam. In the case of stopping the supply to the packing of liners, the reflected beam is covered, the lamp L4 is unlocked, and the relay P4 is triggered, the contacts 1Р4 turn on the lamp СЛЗ and simultaneously the contacts 2Р4 are broken, the drive motor of the stuffed mask is turned off. Due to the delay in the operation of the relay P4 for 5-6 seconds, the signal is turned on and the engine of the ramming machine is turned off only with a prolonged cessation of the sleeves supply.

The device is powered from the AC mains through a TP transformer. For rectifying the alternating current, semiconductor rectifiers D1, D, and Dz were used, assembled on DGTs-27 diodes according to the bridge circuit.
