Abstract

The invention relates to the field of commercial engineering and can be used in machines for the sale of tickets for passenger transport. The aim of the invention is to improve the accuracy of issuing tickets. The goal is achieved by punching the ticket and the device counts the number of perforations by means of a sliding sensor and fixes it in the counters. The controlled frequency divider allows you to quickly rebuild the device for different ticket prices, display units show both the amount of payment and the amount of change. Slipping when giving a ticket does not lead to errors in the counting of tickets. 2 Il.

Description

The invention relates to trade in mechanical engineering and can be used in vending machines for the sale of tickets for passenger transport.

The purpose of the invention is to improve the accuracy of the device.

FIG. 1 shows the structure of the device; in fig. 2 - electrical circuit. ,

The ticketing device contains (fig. 1) micromotor 1, gearbox 2, ticket drum 3, pressure roller 4, tray 5, contact 6, sensor 7, ticket tape 8 with perforations.

The electrical circuit of the device (Fig. 2) contains the electromagnet 9 brakes, the first deprafrator 10, the first counter II, the encoder 12, the contacts of the sensors 13 of the coin mechanism

electromagnet amplifier 14 of the coin mechanism, the first element OR-NOT 15, elements NOT 16-19, the second element OR-NOT 20, pin 21 of the ticket availability sensor, the second counter 22, the second decoder 23, controlled frequency divider 24, generator 25 clock pulses sensor contact

26 executive mechanism, block

27 indications, display unit 28 and engine control unit 29.

The device works as follows.

We pre-punch tickets at the rate of one punching on one ticket, then, when a payment is received, a coin passes through the coin slot, closes one of the coin slot contacts, this signal goes to the encoder 12 and then to counter 11, where it writes the number in the binary decimal code

The value of the coin. When writing a number to the counter, a resolution signal will also come from the coin slot contact to the first element OR NOT 15, then through the inverter NOT to the input of the write enable to the counter. For a non-zero counter, a zero will arrive from the decoder for the element NOT 18 and a series of pulses from the generator 25 will go to the subtracting input of the first counter and subtract until the counter becomes zero. The decoder will receive a prohibitory signal and stop the pulse train. The number of pulses that have entered the counter (for example, 15) will go to frequency divider 2A. The divider is pre-set the division ratio equal to the price of the ticket, for example 4 kopecks. The number of pulses, which will be equal to three at the output of the divider and recorded in the counter, and the number three will remain in the divider. By not zeroing the second counter from the second distributor 23, the permissive potential will go to the engine control unit 29 and start the engine, which will rotate the reel through the gearbox, which will issue tickets, since there is one punch on each ticket. Flexible contact, punching pass, will issue one pulse for each ticket, which will go to the second input of the second counter and deduct one by one for each ticket until the number in the counter becomes zero, then from the decoder will go to the electromagnet and turn off the engine, and turn on the electromagnet 9 brakes. In our case, the device will issue three tickets on the second part of the display unit will indicate the number that remains until the ticket price, in our case - three. This means that when lowering the coin less than the cost of the ticket issuing ticket will not follow, and if more, the balance will be displayed in the frequency divider, and you only need to add up to the ticket price, the device will issue a ticket, and in the first part of the display unit the number of tickets will be displayed. which will give the device. The OR-NOT 20 element controls the electromagnet 14, closing the coin acceptor when the coin is lowered for Gred (1 hr) from the error, as well as until one ticket is issued to the ticket and the signal for the absence of tickets from contact 21 of the ticket availability sensor is received.

When the device is rebuilt for another ticket price, it is enough to change the coefficient equal to the ticket price on the frequency divider, and leave everything else as it is.

Thus, the device will issue as many tickets as the perforations will occur. But since punching will correspond to a ticket, all possible slippage or irregularities in printing tickets, switching to a different format, as well as not equal distance between tickets, will not affect the inaccuracy in counting tickets.
