Description

I

The invention relates to tobacco industry and can be used in machines for attaching tobacco leaves to a cord for giving a signal when sections of a cord with tobacco leaves and sections of a given length reach the cord.

A signal device to machines for attaching tobacco leaves to a cord is known, which contains mobile and stationary electrical contacts, their periodic closing mechanism and electric signal lamp l.

However, the known device does not provide sufficient accuracy to measure the length of the cord.

The purpose of the invention is to improve the accuracy of cord measurement.

This goal is achieved by the fact that the signal device to the machines for attaching tobacco leaves to a cord containing movable and stationary electrical contacts, their periodic closing mechanism and electric signal lamp, is provided with spring-loaded clamps and guides for the thread leading to the fastening of tobacco leaves to the cord, and the mechanism of periodic closing of electrical contacts contains a multistage pulley mounted on one axis and a disk with contact plates fixed on their back sides and size enny therebetween on parallel10 hydrochloric additional similar disk axis, while on the other side disc radially disposed blades which serve for engagement with contact plates.

The drawing shows a kinematic diagram of a signaling device.

The signaling device consists of body 1, spring-loaded clamps 2 and 3, signal light 4, podrzhinzhinennyh guides 5 for the thread, GOING to fix tobacco leaves to the cord, fixed electric contact 6, movable electric contact 7, and

The mechanism of a periodic zamyzhan including a multistage pulley 9 mounted on one axis 8 and a disk 10 with contact plates 11 and 12 fixed on their back sides and an additional similar disk 14 placed between them on a parallel axis 13, while radially located on the other side of the disks blades 15 and 16 serving for

action with contact plates, and the discs are loosely mounted on the axles.

The signaling device is driven from the yarn coming to the tobacco leaf fastening machine to the cord, and there is no kinematic connection between the alarm device and the tobacco leaf clipping machine to the cord. When a sheet fastening machine is operating, a thread thrown through a multistage pulley, 9 rotates it, while the contact plate 1I, after a complete rotation of the multistage pulley, engages with the radially located blade 16 of the disk 14 and turns it one step, after which the contact the plate 11 is disengaged, and the second radially located blade of the disk 14 is positioned in a position that is more convenient for engagement with the contact plate of the multistage pulley. After the latter makes a number of revolutions equal to the number of radially mounted blades on the disk, 14, this disk will come into contact with the radially mounted blade of disk 10 and rotate it by one step, having placed the next blade of disk 10 in a position convenient for entering an engagement with the contact plate 12 of the disk 14; After the disk 14 has made a number of revolutions equal to the number of blades radially mounted on the disk 10, the latter will make one turn of the electrocontact one, thereby closing the mobile 7 and stationary 6 electric contacts, and the operation of a light bulb. During the lighting of the light signal, the supply of tobacco leaves to the conveyor of the machine is stopped; the formation of the idle part of the cord of a fixed length. After that, the supply of tobacco leaves to the conveyor of the machine is resumed. The number of stages on a multistage pulley corresponds to the number of possible sizes of tobacco cord for typical dryers. Spring-loaded clips 2 and 3 stabilize the position of the disks 10 and 14 after turning them one step, and the spring-loaded thread guides 5 tension it and ensure constant contact of the thread with the pulley surface, and at the same time serve to set the desired length another stage of the pulley. In the case of thread breakage or termination of work, it is necessary to set the disks 10 and 14 by their direct rotation to the initial position, which is easy to implement, since the disks are not connected by a rigid kinematic connection between themselves and a multi-step pulleys.

Claims (1)

The device has a simple construction by transferring the thread to the th, small weight, provides a measure of the length of the finished cord on the thread consumption. going to fix the leaves of tobacco, which guarantees compliance with the actual length of the specified. In addition, the device provides a more accurate measurement of the length of the finished cord, will reduce the consumption of metal, significantly reduce the cost of production and give the national household more than 50-100 thousand rubles. cost savings per year, and due to the exact length of the cord, drying conditions are improved, which increases the yield of light tobacco. Claims A signal device for machines for fastening tobacco leaves to a cord contains mobile and stationary electrical contacts, a mechanism for their periodic closing and an electric signal lamp, characterized in that, in order to improve the accuracy of cord strength, it is provided with spring-loaded latches and thread guides, going on the fastening of tobacco leaves to the cord, and the mechanism of periodic zamyzan electrocontact.ktov contains mounted on a single axis multistage pulley and disk, with x backs of contact plates, and disposed therebetween in parallel to the axis, an additional similar disk with the disk on the other side radially disposed blades which serve for engagement with contact plates. 5900837 Sources of information taken into account during the examination 1.
