Изобретение относитс к области весоизмерительной техники.The invention relates to the field of weighing technology.

Известны устройства дл определени количества предметов равной массы в партии, которые состо т из весов и счетного устройства .Devices for determining the number of objects of equal weight in a batch are known, which consist of a scale and a counting device.

В этих устройствах подсчет количества предметов осуществл етс после их взвешивани (не одновременно), что св зано со значительными потер ми времени при работе .In these devices, the number of items is counted after they are weighed (not at the same time), which is associated with a significant loss of time during operation.

Наиболее близким по технической сущности к предлагаемому изобретеиию вл етс устройство, содержащее преобразователь массы партии предметов в электрический выходной сигнал, счетчик массы партии предметов , щифратор, устройство, создающее электрический сигнал, пропорциональный массе одного предмета, -переключатель задани массы одного предмета, циклический счетчик с щиной, схему задержки, устройство дл подсчета количества предметов и счетчик количества предметов.The closest to the technical essence of the present invention is a device containing a mass converter of a batch of objects into an electrical output signal, a mass counter of a batch of objects, an encoder, a device that generates an electric signal proportional to the mass of one object, a one-object mass setting switch, a cyclic counter with the length, the delay circuit, the device for counting the number of items and the count of the number of items.

Однако это устройство имеет низкую производительность и не надежно. Дл повыщени быстродействи и надежности предлагаемое устройство дл подсчета количества предметов выполнено в виде схемы совпадени , поразр дно соединенной с выходами плифратора, ко входам которого подключенHowever, this device has poor performance and is not reliable. In order to increase speed and reliability, the proposed device for counting the number of objects is made in the form of a coincidence circuit, bitwise connected to the outputs of a pliffrator, to the inputs of which is connected

переключатель задани массы одного предмета , и с циклическим счетчиком, вход которого подключен параллельно с входом счетчика массы иартин предметов, а вы.ход схемы совпадени соединен со входом счетчика количества предметов и со входом схемы задержки , выход которой соединен с шиной установки циклического счетчика в нулевое состо ние. Схема задержки выполнена на инверторе .switch for setting the mass of one object, and with a cyclic counter, the input of which is connected in parallel with the input of the mass counter and images of objects, and the output of the coincidence circuit is connected to the input of the counter of the number of objects and to the input of the delay circuit, the output of which is connected to the cyclic counter's bus bar condition. The delay circuit is made on the inverter.

Claims

The device works as follows. The mass of one object is established by means of a switch. A batch of objects, the number of which must be determined, is placed on the lifting platform 1. The force created by the mass of objects is transmitted to the converter 2, which converts this force into a proportional number of pulses fed to the control circuit 3, from which the pulses are fed to the counter 4 5 comtesters and a cyclic counter 6. A matching circuit 10 through an encoder 8 is fed a number from a switch 7 and a number from a cyclic counter 6. When the numbers supplied by the "match circuit" coincide, the last 10 Byrabatyvaet pulse which is supplied to the counter 11 and the number of objects simultaneously on the same pulse, delayed circuit 13 sets the counter 6 to zero state. As the pulses 15 of converter 2 arrive, the cycle repeats. After the batch of items has been weighed, the control circuit 3 stops the pulses from entering the counters 4 and 6. The indications of the mass of the batch of objects, the mass of one 20 objects and the number of objects in the batch are indicated by the corresponding indicators 5, 9 and 12. Formula 1. A weight device for determining the number of objects of equal mass, containing a25 weight converter for a batch of objects — into an electrical output signal, a counter of maosa of a batch of objects, an encoder, a device that generates an electric signal, supporting the mass of one object, a switch for setting the mass of one object, a cyclic counter with a bus, a delay circuit, a device for counting the number of objects and a counter for the number of objects, characterized in that, in order to improve speed and reliability, the device for counting the number of objects is performed as a coincidence circuit, which is connected to the outputs of the encoder, the inputs of which are connected to the setpoint switch for the mass of one object, and with a cyclic counter, the input of which is connected in parallel but with the input of the mass counter of the batch of objects, and the output of the coincidence circuit is connected to the input of the counter of the number of objects and with the input of the delay circuit, the output of which is connected to the cyclic meter installation bus in the zero state.
