SU7594A1 - Device for accounting for shrinkage and amount of material obtained on a loom - Google Patents

Description

In the attached schematic drawings of FIG. 1 depicts a counter indicating the consumption of the warp and weave and the measurement of the resulting fabric; in fig. 2 shows a tool at the machine for measuring the consumable base; in fig. 3 is the same fixture for counting the flow of the weft and in fig. 4 shows a device for measuring fabric obtained on a machine tool.

The counter (Fig. 1) of the proposed device consists of three parts: disk counters A, C, and B of a conventional device, built on the tenth principle. Each of these counters is intended to mark one of the measurements, namely, the warp, weft, or the finished fabric, so that they are attached to special measuring instruments installed in the loom at the appropriate places.

Part A is intended to account for the consumption of the base and is driven by a tapered pinion 1 (Fig. 1), mounted on the first countable disk and coupled to pinch 2, impaled

on the roller 26, driven in rotation by the measuring device (Fig. 2), located at the left. The measuring device (Fig. 2) consists of a needle roller 8 rolled along its bind and connected with a bevel gear 7 coupled to the same gear 5 mounted on the roller 26. In view of the decrease in the diameter of the base of the base during operation, the roller 26 it is made retractable and the measuring device is located in the bearing, which is compressed by the spring 11 so that the needle roller is always in the compressed position relative to the bind.

Part B (Figs. 1 and 4) is intended to take into account the length of the fabric obtained on the machine, which is measured with a needle roller 13 mounted directly on the axis of the first disk 14 of the counter. The needles of the roller 13 enter at the edge of the fabric, and as the fabric moves, the roller 13 and the first disk of the counter 14 are rotated.

Part C (Figs. 1 and 3) serves to take into account the number of wearers and is set in motion by electric current, for which the pin 24, when rotated, closes and opens the current between contacts 25 and 25. Current, passage through an electromagnet 16, attracts or frees the measles 17, equipped with a dog 18, which turns the ratchet wheel 21 by one tooth at each lift of the core 17. The ratchet wheel 21 is bonded to the gear wheel 20, which, in turn, is engaged with the gear wheel 19, which pushes the first disk 19 of the counter one division. When the electromagnet 16 is demagnetized, the measles 17 with its own body drops and transfers the dog 18 to the next tooth of the ratchet.

The subject of the patent.

Device to account for shrinkage and amount of material produced

on a loom, characterized by the use of a disk counter consisting of three parts A, C VI B (Fig. 1), of which part A, intended to take into account the length of the warp, is driven, with the help of a pinion, from the needle roller 8 (Fig 2), pressed by spring 11 to navoy; the part B, which serves to take into account the length of the fabric, is driven by the needles with a needle roller 13 (Fig. 4) adjacent to the fabric; To turn, with the help of the core 17c with the pawl 18, the ratchet 20, transmitting the rotation by the gear to the counter, the circuit including the electromagnet is closed and the weft fork opens.
