SU131555A1 - A counting printer for counting received products and printing receipt checks - Google Patents

Description

The invention relates to a counting machine, devices for automatically counting received products (for example, when receiving milk through a pipeline) and printing receipt checks, containing a contact sensor, an electromagnetic meter printing counter and a mechanism for pulling the dye tape.

A distinctive feature of the proposed device is the presence of a relay contact circuit in it, controlled by means of a key that closes the contacts, and contact control buttons. This scheme ensures the sequential switching on and switching off of mechanisms, which consider the acceptance of them to be taken into account; products, turning on and off the light signaling, indicating: the order of execution of the process of registration and acceptance of products, as well as the inclusion of a printing counter for printing checks and its subsequent cancellation.

A control tape can be used in the device, the reverse side of which is provided with a coloring layer. This makes it possible to reduce the number of red ribbons needed to print checks and control tape at the same time, since the reverse side of the last tape is used for printing checks.

The drawing shows a schematic electrical diagram of the proposed device with regard, in particular, to counting the amount of milk. taken by pipeline.

The alternating voltage goes to the rectifier through a switch that is located at the dispatcher. For an on-site device (for repair, routine inspection, etc.), the TI toggle switch is duplicated by another switch that is in the device.

№ 131555- 2 The milk distributor, having two checks on his hands, drives up to the milk reception station, where the board is lit: “Milk reception, and opens the door of the booth, in which you interfere with the apparatus. If the device is turned on, l-i is ready for operation, through normally close the contact of the relay RZ and contacts 1 and 3 of the microswitch MICH the lamp L turns on, with the inscription: “Connect the hose and lower the receipt. When the check is lowered, the lamp circuit L1 is broken and through the contacts of the relay Pa and P3 and contacts 2 and 5 of the microswitch MICH closes the circuit of the lamp L, with the inscription: "Insert and turn the key. At the same time, through contacts 2 and 5 of the microswitch and the contacts of the PV and PT relays, the relay P switches on. The contacts of the PI relay block the toggle switch TI.

By turning the key, the sensor switches on the pump, the circuit of which is blocked through the relay contacts. When the pump is turned on and the check is lowered. A contact of the LRW flow switch closes the PS relay circuit. The contacts of this relay block the key contacts and turn on the PZ relay, which locks itself and remains in the working position until the end of the cycle. The relay contact Ro includes a counting circuit and prepares a circuit for the EM-P printing electromagnet.

The first electromagnet of the counting mechanism 5UM, is triggered by each pulse sent by sensor D. After each tenth actuation of this electromagnet, there is a short-term closure of the QC contacts located near the first (single) wheel of the counting mechanism, at the value of which is the second electromagnet of the counting mechanism. Thus, the second wheel of the counting mechanism is decimal. After ten operations of the second electromagnet EM2, the third electromagnet is activated through the contacts KKz of the second wheel. After ten triggers of the third electromagnet, the fourth electromagnet EM is activated through the QCD contacts. The electromagnet EA45 on the wheel triggers once per cycle when the Ru relay is turned on and the check is lowered. This turns off the lamp -772 and turns on the lamp L-. with the inscription: "Milk is accepted.

At the end of the milk acceptance, the KPP duct relay automatically switches off the pump and the lamp L with the caption “Milk is accepted. The machine prints on the first check and control tape, after which the last one is taken one step. At the same time, the relay Re de-energizes and by its contact closes the circuits including the EM-P relay of the relay RZ and the lamp // 4 with the caption "Take out the receipt." The relay RZ works with a delay of about 20 ml / sec and breaks the EM-P electromagnet circuit.

The delay time of the relay RD, determined by the parameters of the resistance RI and the capacitance C |, is quite sufficient for obtaining a normal impression on the check and tape.

When the milk delivery controller performs the command “Take out the check, lamp L turns off and through contacts 1 and 3 of the microswitches and contacts of the relay PI, PS and P turn on the relay PI and lamp L with the inscription:“ Lower the second check and press the print button. By lowering the check and pressing the print button / (I secondly close the print electromagnet circuit, but already paired with relay P, which operates with an exposure determined by the parameters of the resistance Rz and capacitance. It is the same order as the parameters of the relay, and breaks the circuit Electromagnet printing EM-P. Simultaneously, the relay RG breaks the relay circuit .Pi, turns on the pulsar (relay PA and PS) and the time relay PB. Relay PI is de-energized and its contact closes the lamp circuit L with the inscription: "Remove the receipt.

The PS relay of the pulspar sends pulses simultaneously to all the electrons of the N.1TY calculating mechanism (with the exception of the fifth EM electromagnet) through the contacts Ki, / (2, Ks, K. As each wheel resets

zero, the corresponding electromagnet is turned off by a related contact (Ki, KZ, Kz or K). After reset to zero after 2-3 seconds. the time relay triggers and the relay breaks the PZ and Ru circuits, i.e., the circuit comes back to its original state and lamp L lights up, indicating that the device is ready for the repeated cycle.

The printing carriage of the printing counter through the check, check and ink ribbons strikes the printing wheels with convex digits leaving imprints on the check and control tape. Both tapes, of which the test tape is provided with a dye layer on its back side, are wound from the feeder during printing and wound on the receiving drum. The tape drive mechanism is a system that uses the reverse motion of the print carriage, carried out with the aid of return springs, to rotate through a certain (adjustable) angle of the receiving drum. In this case, a tension of the ribbons is achieved, which provides a sufficient gap between them and the printing wheels.

The subject is invented and
