In the dispenser loading mode in FIG. 4 and 5 is the same, in the mode of unloading dispensers; in fig. 6 is a diagram explaining the operation of the cm control unit; in fig. 7 is one of the electrical circuits that are used to illuminate the transponders. Open on a mimic. The device of FIG. l) - includes an order block fop, order discharger 2, an indication block 3 (akaza), an order reception block, a control mode switching block 5 a mixture recipe jamming unit 6, a bunker control unit 7, a dispenser control unit 8, a mixer control unit $ mi, counter 10, mixes, block 11 of forming the order fulfillment signal, node 12 bleshzhirovki (filing ei rHnJI, mimic mnemonic scheme 13 of the concrete mixing unit, block 14 of control. Block 1 of forming the order, generator 2 signal of issuing the order and block 3 indicating the image of the remote issued and order. Order block / reception, control switching mode block 5, mix recipe setting unit 6, order fulfillment signal generating unit 1, dispenser control unit 8, 10 metering counter, bunker control unit 7, mixing control unit 9, blocking unit 12 form nodes: control. The control unit 1L and the mimic mimic diagram 13 form a node. The device blocks are made on electromagnetic relays, semiconductor devices, switching and indication elements. The device works as follows. On the order dispensing console, order formation block 1 dials the concrete brand (one of BocbMi or one of three mortar mixes), the number of batches (up to five, they press the order dispenser button, as a result of which order issuance signal is generated in the order dispenser 2. For visual control, the data about the order being issued is displayed in display unit 3. At the order authorization signal, the order receiving unit indicates the brand and the number of batches to be performed at the relevant mixer. receiving the order data 6, the order receiving button on the order receiving block is received, as a result of which an indication of order reception is sent and indicated to the display block 3, and it also sets a semi-automatic or manual. When operating the device in semi-automatic mode, the operator on the unit 6 of the assignment recipe mix determines the brand of the mix to be performed, and the mix recipe is automatically generated (the mix recipe is determined a composition and weight ratios of components). When a brand of mortar mixes is installed, the blocking unit 12 automatically blocks the operation of the automation elements of the metering control unit 8, which ensures the loading and unloading of the dosing aggregate. At block 7, the control of the bunkers, the operator adjusts the corresponding bunkers and, after checking the condition of the concrete mixing unit on the mimic mnemonic 13, as well as the availability of transport, under the mixer according to the indication of the unit for generating the order fulfillment signal, pushes the dispenser loading button on the dispenser control block 8 . On a signal to load the dispensers, components are automatically loaded at the same time to the dispensers, while the water and the two additives are fed in succession in one dispenser. Depending on the position of the switch 15 (Fig. 2) of the control mode switching unit 5, the load is in semi-automatic or manual (i.In semi-automatic, rivers (i.e. when the button is pressed. 16 load of the metering control units 8, the relay 17-20 operates, which, with their normally open contacts, become self-powered. In the power supply circuits of the relay 17-22, normally-connected normally-closed contacts of the external automatics relay started from the corresponding dates are connected via plug connectors Dose Ticks. External auto relays are relays of D-3M type manufactured by the industry and controlled from proximity sensors of type BK-L. D-3M devices are installed in the external automatics cabinet in the operator's room. Dose sensors are located on the dose arrows UTC-00-ZVL6-type dial indicators and UCD-+ OO-ZVPb. The required number of external automatics relays involved in the power supply of relays 17-22 to control metering loads is determined by the number of concrete and mortar grades, the dosage of which a recipe specifying unit 6 CME B When dosing eight grades of concrete and three grades of solution in the circuit (.fig. 2) metering load control (csbn (relay 17), serially connected normally closed contacts of eight D-3M relays are involved, and sand metering load control circuits (relay 18) of consecutively connected normally closed contacts of D-3M electrical relays, cement metering load control circuits (relays 19} serially connected normally closed contacts are also involved in eleven D-3M relays of devices. Due to the fact that water and two types of additives are subsequently loaded into one metering device, then thirty three sensors BK-L (for eight grades of concrete and three grades of mortar) are needed to dose them. ) serially connected normally closed contacts of eleven relays of devices D-ZM are involved. In the control circuit of the loading of an additive of the first type (relay 20, parallel connected normally open contacts of eleven relays of devices D-ZM are involved, whose normally closed contacts zovany power relay circuit 20 ,. as well as sequentially connected normally closed contacts of eleven more relays of D-3M devices. The circuit (Fig. 2) of the loading control of the second type additive (relay 22) involves parallel connected normally open contacts of one-eleven D-3M device relays, whose normally closed contacts are used in the power supply circuit of relay 21, as well as sequentially connected normally closed contacts still eleven D-3M relays Such a connection allows sequential loading of water and two types of additives into one dispenser. Permission to trigger the corresponding dose sensors comes from block 6 of the assignment of the mixture recipe. The switches 23-25 (Fig. 3) of the control unit 7 and the bunkers are used to select the current bin of rubble, sand, and cement. The relay 17, when activated, turns on the solenoid valve of the pneumatic drive of the outlet valve is selected. the new bunker rubble. The loading of the dosing unit with rubble begins, continuing until the corresponding relay of the external automation for the ordered concrete brand is activated. Relay 17 de-energizes and interrupts the loading of rubble into the dispenser. Similarly, sand loading control circuits on the relay 18, cement loading on the relay 19, water loading on the relay 20, loading the first type additive on the relay 21, loading the second type additive to the relay 22. Relay 17 is powered through the rubble feed block 12 ( the second biscuit switch. switch 2b. Mark of the solution of the block 6 specifying the recipe of the mixture) Relay 17 will be energized only when the switch 26 is turned off, which excludes the loading of rubble into the dispenser when ordering the solution.
