Description

Machines are known for measuring the average thickness of the material to be measured, in particular leathers, using measuring and feeding rollers and a summing apparatus. According to the invention, in a similar AianiHne, for the purpose of an automatic iromer of skin thickness at individual points, the measuring surimat is installed in the guide brackets of the movable-and-1d action of a lever interlocked with one or another known transmission with the drive roller coupling clutch.

In FIG. 1 shows a view of a mashina with a side; FIG. 2 - summing device in front when removing the dial; FIG. 3 - the type of summing apparatus in longitudinal section; FIG. 4 is a cross section of this apparatus; FIG. 5 - one of the nodes of the summing device.

The machine consists of the following main parts: a bracket, a summing device and a mechanism371 {a: automatization of measurement.

The bracket 1, which is used for mantizing the parts of the mashina, has a projection to pass the skin.

A rotating roller is fixed in the recess below. The upper part of the bracket has a guide 11 channel in which the rods 4 are driven under the action of a strong spring and are swiveled with a rotating upper measuring roller 3. The roller of the bracket bracket 7 moves along the guide rod 7 of the bracket on the balloon 6.

The top bar of the guides 7 is supported by the microcoupler 9 of the bracket 8, which is connected to the housing of the narrowing unit.

For raising and lowering the upper roller, the lever 12 has a latch, and for moving and lowering the totalizer, the lever 11 also has a latch.

On the pin 4 of the upper roller 3, the abutment rests under the force of the springs of the merit. rod 5 summing apparatus having a toothed rack.

The rod 5 at the top ends with a collar.

At the zero position of the controller, i.e. when the role: -n and 2 and 3 closed

The slide is by itself, the lower end of the rod 5 must abut against the rod of the upper roller 3, and the collar must be summed.

To adjust this position, a micro-screw 9 is used, which guides the plaque and guides 7 and moves the totalizer.

Mounted in their seven-summed apparatus consists of a rod 5 with a rail, the lower end of which is the measuring tip, and the upper end with the shoulder - the stop.

A toothed rack rod engages gear 20. The gear 21 is stationary on the axle with this gear and gear 21 is attached to gear 22. Gear 22 is mounted on the tapered end of the axis 32 with the ratchet wheel 23 and the screw 24. At the other end of the axis 32 also the arrow 25 and the heart1 visible fist 28 are mounted on the cone. The worm 24 is engaged with the worm gear 29, the axis of which is connected to

LIMBOM 26.

When the rod 5 moves upwards, gear 20, rotating with gear 21, rotates gear 22. The ratchet wheel 23 rotates due to the friction in the conical connection 22 with axis 32, the ratchet wheel 23 rotates, the screw to 24 and arrow 25. The screw to 24 rotates the worm gear wheel 29. On the cone of the axis of the CWC; ieca there is a limb 26 "heart-shaped fist 27 (Fig. 3 and 5). As the pin 5 moves downward, gear 20 rotates with gear 21, rotates gear 22. As the snoring dog 31, west into the ratchet tooth 23, does not allow it to rotate, the gear 22 turns idler on the axle cone 32. Consequently in the measurement, the upstroke of the toothed rack rod 5 is used, ai the downstroke is the idle movement.

A ratchet wheel 23 operating in one direction was used as a summing mechanism.

Removal of evidence; water production

transfer of an arrow and a limb in Zero position.

This is carried out by the pusher 30, which turns fists 27 and 28 on the conical necks, fixed on the axis of the arrow 25 and limb 26, overcoming the friction created in the conical joints by the action of springs.

The operation of the summing apparatus is as follows.

When the rod 5 is moved by the toothed rack, the gear wheel 20 will turn on some part of the circle, according to which gear wheel 22, and therefore the ratchet wheel 23, is black & ka 24 and arrow 25 MUST make one turn with the appropriate module. Thus, the movement of the rod 5 will correspond to one rotation of the gear 22, and hence the arrows 25.

The dial is divided into one hundred parts. The price of each division is 0.05 mm.

Cherv to 24 transmits the rotation to the black wheel 29.

With one turn of the worm 29 and the worm gear coupled with it, the forest turns; bristle 26, on which divisions are made through 5 mm of the course of the toothed rack 5. Rod Limb 26 is sector-wise. The counting is based on the indication on the main dial of the summing device.

All counts of the toothed rack of the rod 5 Sum.m. are driven by a preset number of 23, reflecting the result on the dial by means of the arrow 25.

Work on measuring the thickness of the wheels is performed as follows.

The upper roller 3 is raised by the lever 12, which is secured by a latch.

In the span of the brace 1, a measurable skin is inserted, after the roller 3 is lowered, to release the latch.

When ego-m, a gap is formed between the shoulder of the rod 5 and the upper sleeve 10 of the summing device. equal thickened skin.

Further, the summing apparatus b is raised by a lever 11 secured by a latch. The lift is produced by an amount greater than the thickness of the skin, as a result of which the rod 5, abutting the bead BO, the sleeve 10 of the apparatus, is disconnected from the stem 4 of the upper roller 3.

Arrow 25 and limb 26 are set to zero position by pressing the pusher 30 and turning the cams 27 and 28.

The first measurement is carried out by lowering the lever 11 of the Summating apparatus 6. At this time, the sinter 5 is hinged on the rod 4, and the device 6 is lowered until the microscrew 9 rests on the upper bar of the guides 7.

The gears, the ratchet wheel and the black wheel and the worm wheel are counted by the distance traveled by a rack gear equal to the gap formed between the shoulder of the rod and the sleeve of the device 6, which is equal to the skin thickness. After that, raise the summing apparatus by an amount greater than the thickness of the skin.

The pin 5 with the toothed rack is moved downwards in relation to the apparatus. The gears 20, 21 and 22 rotate in the opposite direction, and the ratchet wheel 23, thanks to the dog 31, does not turn back.

Consequently, the arrow and the limb remain on the reading measured in the first measurement.

The second measurement is made in the same way as the first.

The arrow and the limb stop at the sum of the first and second measurements, etc.

At the lowest position of the summing device, skin dragging is unacceptable.

The machine is driven electrically by a motor through a gearbox rotating the main roller, from which rotation is transmitted through the cam clutch 13 to the lower roll having a roll 2, which drives the skin through the measuring roller 3.

From the BASIC of the roller, through a pair of bevel gears, the rotation is transmitted to the roller CO by an interchangeable cam 17, which, after a certain interval of skin movement, turns on lever 11. The latter lowers and lifts summing apparatus 6. Roller 2 stops at the moment of skin measurement by cam 13.

The interchangeable cam 17 as well as the cam 13 can be set to any interval between the measurement points.

The adhesion of the main roller with the roller of the roller 2 is carried out by means of the coupling 14 moved by the cam 13.

The subject matter of the invention.

A machine for measuring the average thickness of leather using measuring and feeding rollers and measuring summing apparatus, characterized in that, in order to automatically measure the skin thickness at specific points, measuring summing apparatus 6 is mounted in guides 7 of the arm of the movable under the action of lever 11 interlocked one or another famous transmission with coupling coupling 14 of the drive shaft of the feed roller 2.
