Description

Known devices for controlling the operation of a printing sewing machine, having a machine cycle sensor, including electric drives of the glue unit, a thread trimming mechanism, printing on a crosslinked check mark block and periodically controlling a photo cell that reads its tag number and switching off the drive of the machine through the relay circuit using the sensors of the non-supply of the notebook, the overflow of the receiving table and the breaking of the threads does not ensure monitoring of the notebooks also by number when ordering blocks with an increased number of notebooks, for example, up to five pieces per block, on which labels of notebook numbers and order are arranged by binary code. To control notebooks by order number, when stitching blocks with an increased number of notebooks, the device described is equipped with an electronic programming unit generating order pulses of a standard notebook number and order code, an electronic mismatch circuit comparing standard code pulses with pulses of a code readable from the notebook and on A valid i circuit of the magnetic stop of the machine. The electronic programming unit is designed in the form of photoresistances fixed on the machine's table, movable notebooks successively darkened by heads, and contact relays included in the circuit, supplying code pulses when the contacts close. The sensor of the machine cycle is designed as a switch rotated synchronously with the machine.

FIG. 1 is a block diagram of the described device ng of FIG. 2nd structural scheme.

The described device is designed to turn off the drive of a printing sewing machine when the notebook is not supplied or fed during the idle stitch, feeds the thread of the wrong order number and order or shank forward when the thread is broken.

No. 117214-2 -

filling in the receiving table with notebooks and ots;, reading notebooks in the samonaklad shop and automatically turning on the mechanisms of the machine for applying glue, cutting threads and forming gauze mesh, printing a check mark on the stitched block and turning off the machine samonaclad.

The device consists of a sensor / machine cycles (Fig. 1), an electronic programmer unit 2, an electronic mismatch circuit 3, an electronic sensor 4 notebook number and an order, a sensor 5 not supplying the notebook during an operating cycle, a sensor 6 without notebooks in the samonaclad store, sensor 7 wire break, sensor 8, filling the receiving table, electromagnetic mechanism 9 for switching off the machine drive, electromagnetic mechanism W for switching on the drive of the glue unit, electromagnetic mechanism L for printing on the stitched check mark block, el Electromagnetic mechanism 12 cutting threads, the electromagnetic mechanism / extension of the brakes of the threads, the electromagnetic mechanism M off the drive of the feeder and signal lights 15.

The sequence numbers of the book block and order notebooks are distinguished by black marks on the folds of the notebooks that are printed along with the text. Code numbers of notebooks and orders built on the binary system. In a book block, for example, up to fifty notebooks can be maximally with fifteen orders, so up to six labels and an order number code up to four are needed to form a notebook number code, and a total of ten labels.

The block diagram of the device is shown in FIG. 2

To perceive the code of the notebook number and order the ten photoresistances of the FS: -FSC) (Fig. 2) (according to the maximum number of code marks) installed over the overlay table of the sewing machine. The illuminator is located above the photoresistors (not shown in the diagram). When the notebook is moved along the surface table, the photoresistance of the notebooks' heads is successively darkened.

Photoresistance pulses through the contact pyramids of the relay Kfli- / C / 7b and manual switches BKi-VK are fed to the preamplifiers and further to the pulse formers F1-FB and to the final amplifier U.

Formed in the programmable block 2, standard pulses of the numbers of the notebooks and the order with the amplifier Y are fed to the mismatch circuit 3.

The pulse program of the order number code is determined by setting the BKi-VK manual switches.

A sensor 4 for reading numbers of notebooks and an order, consisting of an F5 photocell and a UE photocurrent amplifier, is installed above the overhead table of the machine.

The pulses of the sensor 4 are fed to the pulse shaper F and then to the mismatch circuit 3. Scheme 3 mismatch consists of a trigger T and a thyratron Tyr.

If there are discrepancies between the tags of the number of headers and the order read from the notebooks' head with the standard pulses of the code of the notebooks of the order generated by the programming unit 2, the following fails: 3 mismatches, giving out pulses to the actuator 16 of the machine's drive off, turning off the machine’s driving motor 17

The executive relay 16 can be turned on by the sensor 5 failing to supply the notebook during the operating cycle, the sensor 6 is missing the notebook in the samonaklad shop, the sensor 7 is broken and the sensor 8 is filled with the receiving table notebooks.

Programming unit 2, in the time corresponding to the cycle cycle, set by the sensor / machine cycle, switches on and off the electromagnetic mechanism 10 for activating the glue unit, the electromagnetic printing mechanism 11 on the stitched check mark unit, the electromagnetic thread trimming mechanism 12, and the electromagnetic mechanism 13 for sliding the washers deceleration of the filaments, electromagnetic mechanism 14 for shutting down the drive of the feeder and signal lights 15.

The sensor / cycle of the machine is designed as a switch (not shown in the diagram) rotating in synchronization with the machine.

The device proceeds as follows.

Notebooks heads while moving successively darken the photoresistances of PS1-FSU, which give pulses to programming unit 2, which produces standard pulses of the code of the number of notebooks and order. At the same time, the sensor 4 reads the labels of the code of the notebook number and the order from the folding of the notebook and sends pulses to the mismatch circuit 3. If the pulses of the code of the numbers of notebooks and the order do not coincide, the scheme 3 of the discrepancy is triggered, which turns on the electromagnetic mechanism 9 for switching off the drive of the maschine.

At the same time, the programming unit controls the electromagnetic drives of the machine's 10-drive mechanism, the // printing mechanism on the stitched check mark block, the thread-cutting mechanism 12, the meganism 13 of the thread braking spacing, the samonacco drive-off mechanism 14, and the indicator lights off and on 15.

The sensor 5 fails to supply the notebook during the operation cycle, the sensor 6 is absent of notebooks in the samonaklad shop, the sensor 7 is broken and the sensor 8 is filled in the receiving table automatically switches off the mash drive mechanism 9.
