Кроме того, в этом устройстве, о переработке партий текстильного материала судят только по одному параметру - выработке без учета времени простоя оборудования, что не позволяет контролировать техническое состояние оборудова— . нйя, его производительность.The disadvantage of this device is the lack of protection against the receipt of false information in the data collection unit, which is taken from the generation sensors in transient modes of textile equipment operation, as well as in case of false alarms of the sensors themselves for various reasons in the absence of processed material. In addition, in this device, the processing of batches of textile material is judged by only one parameter - production without taking into account the downtime of equipment, which does not allow monitoring the technical condition of the equipment—. Nya, his performance.

Датчик МП-1 электрически связан с триггером Τγ и с триггером 32 (¾) формирования управляющего сигнала, выгод которого подключен на первый вход элемента 33 (Л 1)₍ реализующего функцию И-НЕ. На второй вход элемента 33(Л1) подключен датчик МП-2.

• Устройство контроля работы сновальной машины работает следующим образом.• The control device of the warping machine operates as follows.

В режиме снования при работе машины , микропереключатель 7 датчика МП-2 разомкнут, педаль 3 опущена, муфта 4 сцепления включена и приврдит во вращение 'сновальный барабан 1. В это время микропереключатель 2 датчика МП-1 замкнут В положении а. При этом снята блокировка с триггеров и путем отключения входа 2 от шины Земля*.In the standby mode during operation of the machine, the microswitch 7 of the MP-2 sensor is open, the pedal 3 is lowered, the clutch 4 is engaged and the main drum 1 is screwed into rotation. At this time, the microswitch 2 of the MP-1 sensor is closed in position a. In this case, the lock is removed from the triggers and by disconnecting input 2 from the Earth bus *.

При вращении сновального барабана 1 и контактировании ленты 5 с роликом 12 датчика 11 выроботки происходит поочередное перекрытие светового потока, направляемого от светодиодов Д1 и Д2 к фотодиодам ДЗ и Д4, За каждый оборот ролика 1.2 с фотодиодов ДЗ и Д4 получают по одному импульсу, которые усиливаются с помощью элементов П1, R 1, П2, Я 2 и подаются на входы /и к триггераWhen the warp drum 1 is rotated and the tape 5 is in contact with the roller 12 of the extraction sensor 11, the luminous flux alternating from the D1 and D2 LEDs to the DZ and D4 photodiodes alternates. For each revolution of the roller 1.2, one pulse is received from the DZ and D4 photodiodes, which are amplified using the elements P1, R 1, P2, Z 2 and are fed to the inputs of / and to the trigger

При очередном последовательном перекрытии фотодиодов производят перенос • триггера Τγ в исходное состояние и с его выхода с помощью'блока 31 сбора информации считывают импульсы И 2, число которых пропорционально регистрируемой выработке ленты 5, наматываемой на сновальный барабан 1.At the next sequential overlapping of the photodiodes, the trigger Τγ is transferred to its initial state and pulses And 2 are read from its output using the information acquisition unit 31, the number of which is proportional to the registered output of the tape 5 wound on the warp drum 1.

При наличии только одного импульса, например с ДЗ, который может возникнуть в результате вибрации прерывателя и перекрытии при этом одного из двух светодиодов, например при отсутствии контролируемой ленты, но при включенном датчике МП-1, не происходит переброс триггера Т₇ в исходное состояние, а следовательно исключается возможность регистрации ложной информации по выработка.If there is only one pulse, for example, with a remote sensing element, which may occur as a result of vibration of the interrupter and one of the two LEDs overlapping, for example, in the absence of a controlled tape, but with the MP-1 sensor turned on, the T ₇ trigger will not be reset, and therefore, the possibility of registering false information on the development is excluded.

Для чего с гера на йервый вход Л1 подаютотрицательный сигнал, соответствующий *0*, а на вход 2 — положительный, соответствующий *1*. ⁴ At the same time receive downtime. For this reason, a negative signal corresponding to * 0 * is supplied from the ger to the first input L1, and a positive signal corresponding to * 1 * is input to input 2. ⁴

При этом контакт Ργ разры— ; вает цепь подачи напряжения И, на блок сбора информации, фиксируя отсутствие простоя.At the output L1, and therefore at the I base of the PZ transistor, they receive a positive signal, open the PZ transistor, which turns on the relay у, opening its normally closed contact R ,. Moreover, the contact Ργ breaks; a voltage supply circuit And, to the information collection unit, fixing the absence of downtime.

В этом случае блокирующие входы триггере® Tq , Т^, подключают к шине 'Земля' На первый вход элемента Л1 с выхода триггера подают положительный сигнал, соответствующий '1', а на второй вход - до отрицательный, соответствующий 'О'.In this case, the blocking inputs of the trigger® Tq, Т ^, are connected to the ground bus. A positive signal corresponding to '1' is supplied to the first input of the L1 element from the trigger output, and a negative signal corresponding to 'O' is sent to the second input.

Как и в режиме снования на выходе Л 1 получают положительный сигнал, свидетельствующий о работе машины.As in the warping mode, the output L 1 receives a positive signal indicating the operation of the machine.

На оба вхрда 20 Л1 подают положительный сигнал, соответствующий '1'. На выходе Л1, а следовав тельно и на базе транзистора ПЗ получают ·' отрадительный сигнал^ запирающий транзистор и отключающий реле Р1. В 25 этом случае от блока питания БП через нормально замкнутый контакт подают на блок сбора информации напряжение ЦК,, свидетельствующее о наличии простоя.When the machine stops both in warping mode 15 and in the grafting mode, pedals 3 and 8 are raised to the upper position, the clutches 4 and 9 are turned off, micro switches 2 and 7 of the MP-1 and MP-2 sensors are opened. Both arches of 20 L1 provide a positive signal corresponding to '1'. At the output of L1, and consequently on the basis of the transistor, a PZ receives a “reflective signal”, a locking transistor and a disconnecting relay P1. In 25, in this case, from the power supply unit of the power supply unit via a normally closed contact, the voltage of the central circuit is fed to the information acquisition unit, indicating the presence of downtime.
