Description

Current control device for use in a vending machine.

The present invention relates to a current control device for use in a machine vending machine and, more particularly, to a control device of current that triggers the bill acceptance device of the vending machine in the energy saving mode in standby position when the acceptance device does not receive No ticket

In public places, several can be installed types of automatic vending machines to provide candies, bills, change, etc., when you enter them a Currency or ticket. A large vending machine comprises a bill acceptance device and numerous sales units main. Conventional vending machines usually designed to directly consume the electricity supply general. Once installed, the acceptance device for Tickets stays constantly connected. Since the bill acceptance device is constantly maintained connected, a lot of energy is consumed when the machine is inactive

Therefore, it is desirable to create a power control device, for use in a machine Vending machine, eliminating the aforementioned inconveniences previously.

The present invention has been carried out taking into account these circumstances. Therefore, the main objective of the present invention is to disclose a device of current control for use in a vending machine that automatically pass the bill acceptance device from operating mode to standby mode when the machine is not receiving any ticket, or from the standby mode to operating mode when the Vending machine receives a ticket. According to an embodiment of the present invention, the current control device comprises a pulse signal generator installed at the entrance bill of the machine bill acceptance device  Vending and adapted to generate a command or control signal shot when inserting a ticket at the ticket entrance of the bill acceptance device, a controlling device, and a control device that controls the controller device to pass the bill acceptance device between standby mode, energy saving mode and operation depending on the presence of the pulsating signal from the pulse signal generator. According to one way alternative of the present invention, the control device of current comprises a control device adapted to generate a command signal and a controller adapted to receive the signal of command from the control device. The controller connect the power supply with the acceptance device of bills when receiving the command signal from the device command, or disconnects the power supply from the bill acceptance device upon receiving no signal from the control device.

Figure 5 is an operation flow chart in the standby mode according to the present invention.

Figure 6 is an operation flow chart of the ticket rejection modality according to this invention.

Referring to figures 1 and 3, a current control device (10) constructed according to the first activation mode of the present invention is installed in a vending machine and electrically connects between the bill acceptance device (20) and the main sales units (30) of the vending machine, comprising a pulse signal generator (13), a control device (11) and a controller (12). The pulse signal generator (13) is install at the entrance of the bill acceptance device (twenty). The PIN OUT of the control device (11) is connected to the main sales units (30).

After a predetermined period of time in which the input of the acceptance device (20) does not receive no ticket, the bill acceptance device (20) activates a flip-flop circuit of type D (U1) (111) to transfer the high potential PIN6 to low potential, which causes the PIN5 to be set to zero. At this time, an N-channel field effect transistor (Q2) (121) of the controller device (12) causes it to be disabled a P-channel field effect transistor (Q3) (122), which prevents the main power supply from passing to the device  acceptance of bills (20) and, therefore, the device of Acceptance of tickets (20) directly enters the modality of standby power saving and emits an enable signal EN a a N-channel field effect transistor (Q1) (112) of the control device (11) to keep the PIN OUT in potential high, which informs the main sales units (30) of the standby mode situation of the acceptance device of bills (20). Upon entering standby mode, a module oscillation (131) of the pulse signal generator (13) forces a LED (light emitting diode) (132) to emit light, which is received then in a phototransistor (133) to keep the Vpt in low potential, waiting for the mode of operation.

When a ticket arrives at the entrance of the bill acceptance device (20), block the LED light (132), which causes the RC (resistance-capacitance) is charged to change the Vpt from low potential to high potential and to activate the PIN1 of the type D rocker circuit (U1) (111) and change the PIN5 status of the type D rocker circuit (U1) (111) from the low potential to the high potential. When the PIN5 of the circuit swingarm type D (U1) (111) changes to high potential, it get the N-channel field effect transistor (Q2) (121) activate the P-channel field effect transistor (Q3) (122), allowing the main power supply to reach the bill acceptance device (20). At this time, the control device (11) emits a control signal to drive the channel field effect transistor N (Q1) (112), causing PIN OUT change from high potential to low potential. When PIN OUT changes to low potential, the control device (11) emits a  signal to the main sales units (30), informing the main sales units (30) of the modality status of operation of the bill acceptance device (20).

Figure 2 is a block diagram of a device of the second mode of control device according to The present invention. The current control device (10) is electrically connected between an acceptance device of banknotes (20) and a series of main sales units (30), comprising a control device (11) and a device controller (12).

Referring again to figures 2 and 3, when the main sales units (30) are not activated (their respective buttons are off), the device Acceptance of tickets (20) changes the mode of operation to standby mode. The flow of changing from the operating mode to pause mode is explained to continuation. The diode (D) detects the potential level of PIN OUT. When the high potential of PIN OUT, PIN6 of the type D (U1) (111) rocker circuit of the control device (11) is activated by a low potential, which causes PINS of the type D rocker circuit (U1) (111) of the device command (11) change from high potential to low potential. The signal low potential then passes from the circuit's PIN5 type D rocker (U1) (111) of the control device (11) a through the N-channel field effect transistor (Q2) (121) to the P-channel field effect transistor (Q3) (122), what which causes the P-channel field effect transistor (Q3) (122) prevent the main power supply from passing to bill acceptance device (20) and, therefore, the bill acceptance device (20) enters the mode of Energy saving paused.

When a main sales unit (30) is activated (connected), a pulse is sent via PIN OUT to activate PIN1 of the type D rocker circuit (U1) (111) of the control device (11), which causes the circuit's PIN5 rocker type D (U1) (111) of the control device (11) change from low potential to high potential; this potential high is then sent through the effect transistor channel field N (Q2) (121) of the controller (12) to the P-channel field effect transistor (Q3) (122), so causes the P-channel field effect transistor (Q3) (122) is activated to allow the main power supply go to the bill acceptance device (20), and therefore that the bill acceptance device (20) enters the operating mode

It is therefore appreciated that the device of command comprises an N-channel field effect transistor (Q1), a type D rocker circuit, said circuit having type D rocker of a PIN OUT connected in parallel with a channel field effect transistor N (Q1) to said generator pulsating signals, and a type D rocker connected to said controller device. It also includes a circuit type D rocker connected to said device controller.

In addition, the controller device has a N-channel field effect transistor (Q2) and a transistor of P-channel field effect (Q3) electrically connected to the type D rocker circuit of said control device, said channel P field effect transistor being adapted (Q3) to provide power supply to said tray of Ticket entry Also said controller device has of an N-channel field effect transistor (Q2) and a transistor P-channel field effect (Q3) electrically connected to the type D rocker circuit of said control device, said step channel effect transistor P (Q3) being adapted to provide power supply to said device of Acceptance of tickets.

The pulse signal generator is composed of an RC (resistance-capacitance), a phototransistor, an oscillation module, and an emission diode of light.
