SU27150A1 - Device for automatic stopping in hall machines - Google Patents

Description

 The proposed invention relates to

. switching off devices yes in hall naschin with hook needles. The main patent No. 14243 describes a device for stopping in a die machine, implemented by means of an electromagnet core, provided with a recess for the end of a three-arm arm with a latch abutting a protrusion of a rod. The latter is intended for switching on the driving belt of the machine; when the core is attracted to the electromagnet, which acts upon the formation of a short-term contact from 4pe3MepHQro, tension, breakage of the thread or other defects. Disconnection of the electrical connection of the housing to the winding of the Electromagnet is carried out by a spring, which is connected with the winding and does not touch the switching rod when the machine is turned on. The dependent author's certificate suggests further development of the device described in the main patent, which consists in the fact that the press located in front of the NROL'NY

 The spring-loaded part is held by the protrusion of the core in the working position under the action of the solenoid in the solenoid, when the thread is pulled, or its electromagnetic drive, which releases the press in the ganging system. ,

FIG. 1 is a schematic diagram of an isozkro drawing.

It beats a side view of the device dd autr, a stoppage of a machine in a hook machine with hook-needles, in a partial longitudinal section; FIG. 2 - a view of it The specified arrangement is made of an electromagnetic drive for the press. 49 hook needles, installed for each of the idlers, successively included in the chain of the machine’s combat gear devices, acting when the thread tension increases, if there are defects in it or when the thread breaks. The electric drive magnet drive consists of the switchboard 51, connected in parallel with the press guides of all systems, and turned around. foot axle 52 angular waves; | 4, 50, supporting spring-loaded press49, swiveling Around axis 48. If the thread is excessively tight, the contact hook on the washer and there is no follower; Hipk) down until the contact is in contact; With the contact insulated from the housing of the contact device, it will not close the TBK.

Under the action of a current, the solenoid 51 is rotary, angular, core 50. After the research institute / rotating around an axis, 52, refreshes the press plate 49, which under the action of the spring 53, rotating around its axis 48, moves from the needles to the station shown in FIG. . 2 dotted line, turns off the press and at the same time drive the machine.

The subject matter of the invention.

With the device according to the warrant No. 14243, the use of a spring-loaded press 49 (Fig. 3 and 4) pivoting near the axis 48, which is pivoted near the axis 52, rotary around axis 48 applies

the angular core 50 of the solenoid | l connected with the solenoids of the iressoz of all systems that the troupe has consistently included as a counter-threading device, acts as C 14 with increasing tension of the thread tension or at. their breakage, and with obmbtkoy electromagnet stop. /
