Description

Bistable device for output selection in coin selectors

Field of the Invention

The present invention relates to a device bistable that aims to select the output by which a coin entered in a selector must be addressed complying with the premise of allowing in one state the opening of one of the two exit doors blocking the opening of the other, and in another been exactly the reverse situation.

The design of the device allows its application in the two most generalized types of selectors, the outputs of lower rejection and acceptance and front rejection output and lower acceptance.

The invention is framed in the sector Technical-industrial coin selectors for coin activated machines, preferably machines type "vending", recreational machines or public equipment of telephony.

Background of the invention

Quite often some selectors of currency present the problem of producing failures of operation, especially due to the random movement that the coins describe inside the selector and that therefore causes the one that leaves the selector for the unselected output, thus generating an anomalous situation, typifiable even as of involuntary "fraud."

Therefore it is necessary to have a design structural interior of the selector that allows to strengthen its Reliability and response regarding return and / or acceptance correct currency once its validity is determined, which also understand a blocking situation for one of the exits when the Another is enabled.

To this problem should be added that; exist two types of selectors usually more commercialized with different output configurations, rejection outputs and lower acceptance and front rejection output and lower acceptance, and that is also a necessary design condition that the mechanical elements that integrate them are common and of Low profile, to achieve low cost.

Description of the invention

The device of the invention resolves the perfection the problem posed by such a simple solution as effective and functional, based on a structure that includes mainly a bistable or trigger device that meets the double objective pursued of, block one exit when the other is enabled or open, and that the trigger is valid for both More generalized types of coin selectors.

To do this, the trigger materializes in one piece flattened and capable of turning with respect to a central axis, equipped with four corners or arms acting as limiters or career ends to prevent or allow the tilting of floodgates of rejection or acceptance outputs by blocking one of them when the other is enabled and vice versa.

Two of the arms of one end of the trigger are provided for one type of selector and the other two of the other extreme, for the other type of selector.

The trigger is activated by means of an arm or motorized connecting rod by means of a solenoid that receives the instructions for action by the means of verification and previous selector detection.

Thus, the first position or position initial of the bistable trigger of the invention, which in turn corresponds to the solenoid resting position, allows the tilt of the door corresponding to the rejection exit, while in the second position or final position of the trigger flip-flop, the rejection output is blocked and the tilting of the door of the exit of acceptance. With it it also fulfills the condition that in the absence of tension, the selector return all coins entered in the selector.

For their part, the floodgates take a form angled, which on one side comprises the wall that comes into contact with the coins, allowing or preventing their passage, and in the other, a counterweight that keeps them in their resting position against the Coins pass through the corresponding lane, and in turn, about protrusions that in collaboration with the corners of the trigger flip-flop, allow the flip-flop and lock situation of the door not selected.

The versatility of the device of the invention is such that the simple placement of the trigger in a second position rotated 180º with respect to the first one, makes the trigger for the second type of selectors mentioned.

Thus, the device of the invention has three Advantages and essential features:

one.

The bistable piece is designed in a switched mode, that is, it serves for the two types of selectors (front and bottom),

2.

He trigger is bistable, that is to say that it is assured by design that when one door opens, the other remains closed and vice versa, and

3.

He design does not include metal parts except for the solenoid and its spring, which directly results in a low manufacturing cost being mostly plastic parts.

Ramp for front exit of coins

For a perfect understanding of the type of selectors to which the device of the invention, a selector (1 ') is shown in figure 1A commonly called lower output, in which both the output of acceptance as the rejection exit, are located in its part lower.

This comprises an entry (E) for introduction of coins and two exits, one of acceptance (A) and lower, and another of rejection (R) and frontal.

Figure 1B shows the other type of selector (1), the commonly called front selector, because it is usually used on the front of the machines where they are placed, and in which the rejection output (R) is located in the front of the selector and the acceptance output (A) is located in the bottom.

Well, based on this definition of two types of selectors, and taking as the first embodiment the corresponding to a rejection output selector (1) (R) in the front, this comprises, as shown in Figure 2, a bistable trigger (2), attached by a harpoon shaft (3) to the body of the selector (1), and operated by means of an arm or connecting rod (4) guided and subject to said selector body by harpoons (12), and a arm (4) connected at one end to the bistable trigger (2) and by the other to a plunger (5) of a solenoid (6), arm (4) that once activated produces the displacement towards the solenoid (6) of the bistable trigger (2). The arm (4) engages and acts with the trigger flip-flop (2) by means of a projection (20) provided in its surface, which crosses it from one end to the other, and a hook or tooth provided in turn at the end of the arm itself (4).

Once the solenoid (6) is deactivated, that is interrupted the current flowing through it, a spring (8) previously compressed by the action of the arm (4), it makes recover to the whole set the initial or resting situation.

The displacement or contraction movement, exerted by the solenoid (6) to its plunger (5) which when bound the arm (4) transmits it to the trigger (2) by moving it in the clockwise, clearly defines the two possible set situations, an initial position (Pi) and a position final (Pf). These two positions can be seen in Figure 3, where the direction of rotation of the bistable trigger is represented (2) and the direction of movement of the arm (4).

The initial position reset (Pi) of the bistable trigger (2) (figure 4) is determined by the deactivation of the solenoid (6), so that the spring (8) is relax tending to return to your resting situation and making the arm (4) returns from its final position (Bf) to its position initial (Bi). In this way, the bistable trigger (2) now rotates in counterclockwise and reaches its position initial (Pi).

This set, solenoid (6), arm (4) and trigger flip-flop (2) interacts with the selector output system (1) through its door of acceptance (10) and the one of rejection (9).

These doors are subject and equipped with tilt capacity, with respect to the selector body (1) by means of axes (15, 15 ') embedded in harpoons (11), and preferably have an angular movement of 60º, always that the bistable trigger (4) does not get in its way through of the ends of the arms (13) and (14) (figure 4).

Also, the doors comprise a gate (18, 18 ') located on the path of the coin, and orthogonally a counterweight (16, 16 ') and a stop (17, 17').

So, in figures 6A to 6D you can the general operation of the device of the invention.

Figure 6A shows a coin (M) moving through the internal channel (CI), a door (P) with its counterweight (CO), which is held in a closed position by gravity and making contact with the stop (T) of the output body that limits its travel.

Figure 6B shows when the coin (M) rests on the door (P) and due to its greater weight with respect to the counterweight (CO) of the door (P), the door (P) ends up opening allowing the coin (M) move towards the exit. Once the coin (M) exceeds the door (P), it returns to its initial closed position (figure 6C) by the force exerted by the counterweight (CO), leaving the door (P) as the final result in the same position of the figure
6A.

In these three figures (6A to 6C) the trigger (G) has remained without activating, that is to say in initial position (Pi), for what if you act on it by changing it to its final position, as seen in figure 6D, then the door is impeded to turn as it collides at the point (PA), thus making it impossible to The currency continues its pace.

In particular, and making reference direct to this embodiment of the invention, in figure 7 you can see the back of the selector body (1) where the coin (19) rests between the two doors (9), (10), so that only one of them will allow him to pass, with what the trigger (2) only opposes the turn of one of the aforementioned doors, which gets in the way of the coin towards the allowed exit. In this same figure shows the ramp (21) that empowers the selector (1) so that the coins (19) go out the front of it.

On the other side of the selector body (1), (figure 8), it can be seen on the one hand as the arm (13) of the trigger (2) collides with the stop (17 ') preventing the tilting of the door (10), while on the other hand the door (9) does not finds limitation to its tilting, by not making the end stop (14) of the trigger (2) with the stop (17).

Consequently, currency (19) expires by weight at the door (9) that is not limited in terms of its tilt and head towards the rejection exit (R).

Thus, with the structure described, they get two perfectly defined states, state 1 and state 2.

State 1: In this state the door (9) is It is open and the door (10) closed. Therefore the first requirement of every selector, by which every currency that enter a selector (1) in the absence of power, you must  return to the customer through the rejection exit (R) (figures 9 and 10).

State 2: In this state the door (9) is find dinner and the door (10) open.

To achieve this state, the solenoid (6) to cause displacement of the arm (4) and solidarity the angular rotation of the bistable trigger (4), so that the arm (14) collides with the stop (17) and therefore prevents door tilting (9). In turn, the arm (13) is not left facing the stop (17 '), does not oppose the turning of the door (10) and therefore it allows it to spin freely and that the coin reach the acceptance outlet (A) (figures 11 and 12).

In the other selector mode (1 '), that of Departures. of lower acceptance (A) and rejection (R) as see in figure 1A, the bistable trigger (2) is mounted rotated 180º (figure 13) with respect to the front selector configuration (1) (Figure 1B), and the other two arms come into operation available (13 ', 14'). In this selector configuration (1 ') the Acceptance (A) and rejection (R) outputs change location (figure 14) providing the output channels directly vertically in the bottom of the selector for gravity drop of the coins (19) after exceeding the doors (9) or (10)

So, the operation of this selector (1 ') basically follows the philosophy of the previous selector (1). When solenoid (6) is activated and its axis retracted, the arm (4) keeps the spring (8) contracted and the bistable trigger in its final position (Pf), the arm (13 ') of the trigger (2) keeps the door (10) closed, and the arm (14 ') allows free tilting of the door (9). If at this time a coin (19) impacts on both doors as seen in figure 14, the door (9) opens letting the coin (19) pass until the acceptance exit (A) as it is seen in figure 15, and once the coin (19) leaves the selector (1 '), the door (9) returns to the resting point per action of its counterweight (16 ').

In the other state, that is deactivating the solenoid (6), the spring recovery force (8), displaces the arm (4) to its initial position and consequently to the trigger flip-flop (2), the arm (14 ') opposes the tilting of the door (9) by action of the confrontation with the stop (17), and the arm (13 ') releases the door (10), remaining as shown in the figure 16.

Therefore, if one currency (19) impacts both doors, the door (10) will move by the weight of the coin (19), letting the latter advance until the rejection exit (figures 17 and 18).

With both selector solutions you have ensured that a coin (19) comes out at all times through the door selected, while at the same time the opposite door remains closed by the action of the bistable trigger (2).
