SU98705A1 - Device for controlling the operation of a printing sewing machine - Google Patents

Description

In the existing service of automatic threading machines used and printing production for stitching notebooks in book books, stopping; machines in the event of a lack of notebooks on the supply table, when the correct amount of time has passed; due to thread breakage of the sewing machine, switching on the mechanisms of cutting 1; ons1 of the lines and sizing of the roots, as well as the imprinting of the pa block), control checks are performed manually.

This complicates the work of the operator and does not allow the yjie.T t4HTb to have an air capacity of ash. Known in the technique, the devices controlling the operation of the pitching machines, made in the form of a cam distribution unit, including alternately cut ends of the thread and gluing the roots, do not automatically change the cycle of operation of these mechanisms when changing the number of notebooks in the block, do not provide automatic control of the machine in stopping it in the case of ashes, they give an impression of the check mark.

The proposed device for controlling the operation of the printing and sewing machine consists of ten knots mounted on the machine and consisting of a single unit with it.

The group of nodes of uravleni includes (Fig. 1-3); cam dec)) is simple, p1 node (1), kinematically connected with the main unit installed and intended to switch on the circuits of the electromagnets of the power assemblies and the circuits of some control nodes; unit (2) of stopping the machine, made in the form of electro5 agppt, connected with the scab included) 1 of the friction clutch, and intended to stop the machine in the event of malfunctions in its controlled parts; node (3) of the control and alarm system in the form of a switchboard shield, on which signal lights are installed to notify the operator about the stop of the machine.

The soil of the control nodes includes: a node (4) of photoelectric control of the presence of notebooks on the supply table; photovoltaic control unit (5) on the order of notebooks entering the machine; node (6)

Claims (3)

1. A device for controlling the operation of a full-graphical sewing machine, consisting of a kinematic cam-distributor node connected to a main machine, including contacts of a solenoid, which triggers the actuator units, of which it operates. For the purpose of controlling the operation of the machine, control units are introduced into the device for photoelectric or electromechanical monitoring of the presence of notebooks on the feeding table, the order of entering the notebooks into the machine, filling the receiving table and the operation of the sewing machine, causing the machine to stop in case of malfunctions, as well as control and signaling unit, informing the operator of the irradiation of the machine 2. The form of the device according to claim 1. That is, so that, in order to change the response points of the executive and some control units, depending on the change in the number of tetraj in the unit, the distribution node is designed as a detachable value with adjustable cams so that the duration of the cycle of its operation with respect to the 1C cycle of the machine can be changed. 3. The form of the device according to p. 3. About tl and ch and so that the node of the photoelectric control order of entry of notebooks in the machine is made in the form of an illuminator and photoeleite, whose circuit is closed by the distributor node pouring the passage of the passage of the notebook with advance the established normal number, and on the spine of the indicated notebook there is a mark in the form of a black spot, liTcyTcinne of which causes the penetration of | 1 tract; about 1 puff from the spine of the rays on the photonelements and the machine stop. J. The form is made of the device according to claim 1, so that, for the purpose of quality of work, the knot of imprinting on the stitched check mark blocks assigned to this machine is entered into the number of internal nodes.
