Description

Изобретение относитс к области автоматического регулировани неэлектрических величин, в частности к устройствам дл автоматического регулировани подачи воды в промывные ванны, например, в производстве гальванических и химических покрытий .The invention relates to the field of automatic control of non-electric quantities, in particular, to devices for automatically controlling the supply of water to washing baths, for example, in the manufacture of electroplating and chemical coatings.

Известны устройства дл автоматического регулировани подачи воды в промывные ваннь, содержащие счетно-решающие устройства и соединенные с ними датчики и исполнительные механизмы 1.Devices are known for automatically regulating the supply of water to the washing baths containing calculating devices and sensors and actuators connected to them 1.

Недостатком таких устройств вл етс невысокое быстродействие, что обусловлено необходимостью последовательной подачи воды во все промывные ванны независимо от их загрузки.The disadvantage of such devices is low speed, which is due to the need for consistent supply of water to all the washing baths, regardless of their load.

Наиболее близким техническим рещением к изобретению вл етс устройство дл автоматического регулировани подачи воды в промывные ванны, содержащее блоки переключени по числу ванн, первые выходы которых подключены к соответствующим исполнительным механизмам, установленным в трубопроводах подачи воды в промывные ванны, а первые входы - к выходуThe closest technical solution to the invention is a device for automatically regulating the supply of water to the washing baths, containing switching units according to the number of baths, the first outputs of which are connected to the corresponding actuators installed in the water supply pipelines to the washing baths and the first inlets to the outlet

концентратомера, установленного в общем трубопроводе слива, а также датчик тока 2.a concentrator installed in the common drain pipe, as well as a current sensor 2.

Это устройство имеет невысокое быстродействие , так как не обеспечивает подачу воды в промывные ванны непосредственно после их загрузки. Кроме того, в процессе работы устройство включает подачу воды последовательно во все промывные ванны в каждом рабочем цикле независимо от наличи в них деталей, что цриводит к избыточному расходу воды.This device has a low speed, because it does not provide water to the wash baths immediately after their loading. In addition, during operation, the device turns on the water supply successively to all the washing baths in each working cycle, regardless of the presence of parts in them, which leads to excessive water consumption.

Целью изобретени вл етс повышение быстродействи устройства путем включени подачи воды в промывные .ванны одновременно с их загрузкой.The aim of the invention is to increase the speed of the device by turning on the water supply to the washing baths at the same time as they are loaded.

Поставленна цель достигаетс тем, что устройство дл регулировани подачи воды в промывные ванны содержит датчики загрузки ванн и элементы И по числу ванн, первьте входы которых подсоединены к датчикам загрузки ванн, а все последующие - к выхода1;1 всех предыдущих блоков переключени , вторые входы которых подключены к выходам соответствующих элемг нтов И.The goal is achieved by the fact that the device for regulating the supply of water to the washing baths contains bath loading sensors and elements AND by the number of baths, first of which the inputs are connected to the bath loading sensors, and all subsequent ones to output 1; 1 of all previous switching units, the second inputs of which connected to the outputs of the corresponding elements I.

Claims

The drawing shows a functional diagram of the device. 3651 It contains li-U wash baths, load sensors for baths 2 -2p, elements 3i-3, switch units, a concentrator meter 5, a common drain line 6, actuators 7-7 and transfer pipes 8: -8p. for draining the water from the wash baths into the common drain pipe. The number of inlets for each element I is equal to its serial number. The device works as follows. In the initial state, the li-1l wash baths are not loaded. The signals from the load sensors of the baths 2 -2a, at the output of the elements And 3i-Zn., Are absent at both inputs and first outputs of the switching units 4i-4. At the second outputs of the switching units 4i-4c. and connected with them the inputs of the elements And 3i -Zp. there is a signal. When one of the baths is loaded with lj (j 1, n) parts, its load sensor 2j produces a signal that goes to the first input of the corresponding element And 3j, the remaining inputs of which receive a signal. The bursts from the second outputs of the 4i-4J-1 switching units, which have a smaller sequence number. At the output of the element And 3j, a signal is generated which is fed to the second input of the switching unit 4j. The switching unit 4j is turned on and the signal generated at its first output turns on the actuator 7y. In this case, water is supplied to the bath Ij. From the bath Ij, it is drained through the overflow pipe Sj into the common drain pipe 6 and passes to the concentrator 5. If the content of the components of the contaminating impurities in the water above the specified level is controlled by the concentrator 5, the water is fed until the water purity given requirements. When a given water purity is reached, a pulse is generated at the outlet of the concentrator 5, which is supplied to the first inputs of all switching blocks 4i-4d. In this case, the switching unit 4j is turned off, the signal at its first output is reduced to zero, the actuator 7y is turned off, and the water supply to the bath 1 is stopped. If, when washing parts in the bath ij, for example, a bath Ij-a with a smaller serial number is loaded, the 4y-g switching unit is connected to this bath, the signal at its second output and the input of the element I 3j connected to it, as well as at the output element, and 3j is reduced to zero. In this case, the switching unit 44 and the actuator 7j are turned off and remain in this state until the end of the washing of parts in the bath Ij-a having a smaller sequence number. The washing of parts in the lj-i-In. Baths, which have a larger number than the bath Ij, is possible only after the completion of the washing of parts in the bath Ij. The proposed device allows reducing unproductive time losses when washing parts, improving the quality of parts washing in combination with adjustable water flow. Apparatus of the Invention A device for regulating the supply of water to washing baths containing switching units according to the number of baths whose first outlets are connected to the corresponding actuators installed in the water supply pipelines to the washing baths and the first inlets to the outlet of a concentration meter installed in a common drain pipe characterized in that, in order to increase the speed of the device, it contains bath loading sensors and components And by the number of baths, the first inputs of which are connected to the loading sensors n and all subsequent - to the second outputs of all preceding switching units, the second inputs of which are connected to the outputs of the respective elements I.
