Description

The invention relates to a measurement technique and can be used in the textile and clothing industry to measure the dimensions of rolled textile materials.

The purpose of the invention is to improve the measurement accuracy by continuously tracking the sensors behind the edges of the moving material.

FIG. 1 shows the proposed device, top view; in fig. 2 shows section A-A in FIG. one; on fig.Z - section bb in fig. 2

A device for measuring the width of a moving material contains a base 1, guides 2 mounted on it, two sensors tracking the edges of the moving material 3, each of which consists of an illuminator 4 and two photo cells 5 mounted on sliders 6 and 7, driving the sliders along the guides 2 across the moving material 3, a recorder of the dimensions of the width of the material (not shown) and a means of controlling the recorder of the dimensions of the width of the material.

The drive movement of the sliders 6 and consists of two gearmotors 8 and 9, located on both sides of the moving material, placed on the shaft of each gearbox motor drive pulley 10 and freely rotating pulley 11, and two closed drive belts 12 and 13, while driving The belt 12, with the slider 6 fixed on it, bends around the drive pulley 10 of the gearmotor 8 and the free-spreading pulley 11 of the motor gearbox 9, and the drive belt 13, on which the slider 7 is attached, bends around the drive pulley 10 of the gearmotor 9 freely rotating pulley 11 moto p-reducer 8 and block 14 located on slider 6. Photo cells 5, on slider 6 and 7 are electrically connected to gearmotor 8 and 9 via a control unit (not shown).

A control device for the dimensions of the width of the material placed on the slider 6 consists of a gear coupling, one coupling half 15. which is rigidly connected to the block 14, and the second coupling 16 is freely placed on the axis 17 of the block 14 and pressed to the coupling half 15 by a spring 18, two electrical contacts 19 and 20

contact 19 is installed on slider 6, and contact 20 on half coupling 16, and two stops 21 of rotation of half coupling 16, the distance between which is proportional to the tolerance on the size of the width of the moving material 3,

For visual reading of the dimensions of the width of the material 3, a measuring ruler 22 is placed on the surface of the drive belt 13, and the pointer 23 of the size of the width of the material and magnifier 24 is fixed on the slider 6. The device works as follows.

When material 3 moves along base 1, gearmotors 8 and 9 turn on, which move drive belts 12 and 13 with slider 6 and 7 mounted on them across the moving material 3 until one of the two photo cells 5 mounted on each slider, there is no darkened edge of the moving material. When the edges of the material 3 are shifted to the right or left in the same direction, the sliders 6 and 7 are shifted, and by changing the direction of the edges of the material, the direction of rotation of the respective gearmotors 8 and 9 is switched according to the signals from the photo cells 5 through the control unit. In this way, the edges of the moving material are continuously monitored and the width of the material is measured.

When the width of the moving material 3 increases or decreases, the distance between the photocells 5 on the sliders 6 and 7 increases or decreases, respectively, and at the same time the axis 14 of the sleeve 14c rotates on its axis.

When the width of the material goes beyond the limits, the tolerance floor of the half coupling 16 rotates up to the stop into the stop 21 and it disengages from the coupling half 15, with the coupling half 16j pressing the spring 18, moves along axis 17 and closes contacts 19 and 20, and the electrical signal goes to the size recorder the width of the moving material (not shown), which records the size of the width of the material beyond the tolerance field, and the length of the material, where this is the case .;

instead of

When the coupling half 13 lump 14 rotates the half coupling 16 to the angle equal to between the teeth of the coupling, the coupling 16 under the action of the spring turns to the back of the step between the teeth in reverse, moves away from the limiter having closed the contacts 19 and 20, the device returns to its original position

When manually registering the width of a moving material, they are read through a magnifying glass with a measuring line of any size.
