На чертеже изображена блок-схема предложенного устройства.The drawing shows a block diagram of the proposed device.

Установка содержит блок-задатчик 1 кодов адресов, в котором число выходов равно числу адресов складирования и они соединены со входами блока 2 счета сигналов и схем ''Запрет'' 3. Блок 2 счета сигналов имеет счетчики и задатчики количе ства посылок по каждому адресу и соединен с блок-схемой И-ИЛИ 4 и схемами '’Запрет'* 3, выходы которых подключены через элементы ''Память'' 5 ко входам блок-схемы И-ИЛИ 4 и к блоку-шифратору 6. Блок-схема И-ИЛИ 4 состоит из схем И, число которых равно числу адресов, и схемы ИЛИ, входы которых подключены к выходам схем И.The installation contains a block-setter 1 of address codes, in which the number of outputs is equal to the number of storage addresses and they are connected to the inputs of block 2 of the signal counting and the `` Prohibition '' schemes 3. Block 2 of the signal counting has counters and setters for the number of parcels at each address and connected to the AND-OR 4 block diagram and the `` Prohibition '* 3 circuits, the outputs of which are connected via the' 'Memory' '5 elements to the inputs of the AND-OR 4 block diagram and to the encoder block 6. The block diagram AND OR 4 consists of AND circuits, the number of which is equal to the number of addresses, and OR circuits, the inputs of which are connected to the outputs of circuits I.

На вход каждой схемы И поступают сигналы с соответствующих элементов ’’Память*' 4. Шифратор кодов адресов преобразует сигналы на одном из своих входов в двоичный код. Выход шифратора кодов адресов соединен со входами триггеров 7 стартовых позиций канала передачи адресной информации, представляющей собой триггеры с раздельными входами и входной логикой. Количество триггеров в регистре равно числу разрядов кода. Схема И—ИЛИ 4 подключена к триггерам для передачи информации наполнения накопителей 8. Управление передачей информации по регистрам адресов 9, представляющим собой триггеры со счетными входами и входной логикой и триггерами 10 канала передачи информации наполнения накопителей, осуществляется блок-схемой сдвига 11, содержащей генератор,импульсов с дешифратором, который в свою очередь запускается от датчика 12 шагов пе- ремещения конвейерной ленты.The input of each AND circuit receives signals from the corresponding elements ’’ Memory * '4. The address code encoder converts the signals at one of its inputs into a binary code. The output of the address code encoder is connected to the inputs of the triggers 7 of the starting positions of the channel for transmitting address information, which is triggers with separate inputs and input logic. The number of triggers in the register is equal to the number of bits of the code. The AND — OR circuit 4 is connected to the triggers for transmitting information about filling drives 8. The transmission of information through address registers 9, which are triggers with counting inputs and input logic and triggers 10 of the drive filling information transfer channel, is controlled by a shift block 11 containing a generator , pulses with a decoder, which in turn is triggered by the sensor 12 steps of conveyor belt movement.

Каждый регистр адреса 9 подключен к блоку-дешифратору 13 кодов адресов. Триггеры канала передачи информации наполнения накопителей 10 соединены с блоками схем И 14. Дешифраторы 13 через усилители 15 подключены к приводам исполнительных механизмов накопителей 16 и через схемы И 14 и усилители 17 - к световым табло 18.Each address register 9 is connected to the decoder unit 13 of the address codes. The triggers of the data transfer channel of the filling drive 10 are connected to the blocks of circuits I 14. The decoders 13 are connected through amplifiers 15 to the actuators of the drives 16 and through circuits I 14 and amplifiers 17 to the light panel 18.

Устройство для управления сортировкой штучных грузов на конвейерах работает следующим образом.A device for controlling the sorting of piece goods on conveyors works as follows.

При поступлении посылки на стартовую позицию шагового конвейера оператор вводит адресную информацию, соответствующую сортности посылки через блок-задатчик 1 кодов адресов. При этом адрес накопителя, в который направляется единица груза, преобразуется блоком-шифратором 6 в двоичный крд и считывается блоком 2 счета сигнадов. Синхронизация движения посылкй и ее кода по каналу передачи адресной информации обеспечивается поступлением шаговых импульсов от датчика 12 шагов конвейерной ленты. Датчик 12 шагов выдает импульсы в блок-схему сдвига 11 через определенные интервалы передвижения ленты шагового конвейера.When the parcel arrives at the start position of the stepping conveyor, the operator enters the address information corresponding to the grade of the parcel through the address block 1 address codes. In this case, the address of the drive to which the unit of cargo is sent is converted by the encoder unit 6 into a binary card and read by the signature account unit 2. Synchronization of the movement of the parcels and its code along the channel for transmitting address information is provided by the arrival of step pulses from the sensor 12 steps of the conveyor belt. The sensor 12 steps generates pulses in the block diagram of the shift 11 at certain intervals of movement of the tape of the step conveyor.

При подходе посылки к первому накопителю (последний на чертеже не показан) адрес от триггера 7 стартовых позиций, переносится в ре гистр адреса 9, а триггер 7 возвращается в исходное положение и готов к принятию информации адреса места доставки очередной посылки.When the parcel approaches the first drive (the last one is not shown in the drawing), the address from the trigger 7 of the start positions is transferred to the address register 9, and the trigger 7 returns to its original position and is ready to accept the information of the delivery location address of the next parcel.

Если код, занесенный в регистр адреса 9 соответствует коду, формирующему выходной сигнал на выходе дешифратора 13, то это значит, что посылка прошла на конвейере расстояние до места доставки. В этом случае с выхода дешифратора 13 сигнал совпадения поступит на вход усилителя 5, который предназначен для управления приводом исполнительного устройства 16, снимающего груз с конвейера и помещающего в накопитель.If the code entered in the address register 9 corresponds to the code generating the output signal at the output of the decoder 13, then this means that the parcel has passed the distance to the delivery location on the conveyor. In this case, from the output of the decoder 13, the coincidence signal will go to the input of the amplifier 5, which is designed to control the actuator 16, which removes the load from the conveyor and puts it in the drive.

Число посылок, поступающих в каждый накопитель, не должно превышать заданного. Для этого в устройстве предусмотрен дополнительный канал для передачи информации наполнения накопителей, в котором перемещение информации происходит параллельно с кодом адреса, по которому блок 2 счета сигналов выдало этот сигнал.The number of parcels arriving at each drive should not exceed the specified one. For this, an additional channel is provided in the device for transmitting storage filling information, in which the information is moved in parallel with the address code at which the signal counting unit 2 issued this signal.

Сравнение сигнадов, поступающих с задатчика 1 кодов адресов и блока счета сигналов, производится схемой И—ИЛИ 4. Появление сигналов на обоих входах одной из схем И 14 означает, что в данный накопитель поступила последняя для данной комплектующей партии единица груза, при этом сигнал с выхода схемы И 14 поступает на усилитель 17, который включает световое табло 18, оповещающее о том, что данный накопитель заполнен и его следует заменить свободным.A comparison of the signals coming from the address code setter 1 and the signal counting unit is performed by the AND — OR circuit 4. The appearance of the signals at both inputs of one of the AND 14 circuits means that the last unit of load arrived in this drive, while the signal from output circuit And 14 goes to an amplifier 17, which includes a light panel 18, indicating that this drive is full and should be replaced with a free one.

Для исключения возможности попадания груза в заполненный накопитель к выходам блока-задатчика 1 кодов адресов- подключены схемы ''Запрет'' 3, управляемые блоком 2 счета сигналов. При появлении сигнала на одном из выходов блока 2 счета соответствующая схема ''Запрет¹' прерывает цепь прохождения сигнала по данному адресу от задатчика 1 кодов адреса к шифратору 6. Для фиксации сигнала посылки после его снятия в устройстве блока 1 или срабатывания схемы ''Запрет'¹ 3 служит схема ''Память'¹ 5.To exclude the possibility of cargo getting into the filled drive, the outputs of the setpoint unit 1 of the address codes are connected to the “Prohibition” 3 circuits controlled by the signal counting unit 2. When a signal appears at one of the outputs of the account unit 2, the corresponding “Prohibition ¹ ” circuit breaks the signal path to the given address from the address code encoder 1 to the encoder 6. To fix the sending signal after it has been removed in the device of unit 1 or the circuit has been triggered '' Prohibition ' ¹ 3 is the scheme''Memory' ¹ 5.
