Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is designed to collect cards, i.e., relatively thick rectangular pieces of paper, plastic sheets, or similar materials with appropriate elasticity, from a predetermined stocker. It relates to a device for dispensing cards one by one, and is used, for example, in a card dispensing device in a telephone card vending machine.

(Prior art and its problems) Conventional devices of this type have adopted a so-called suction method using suction cups to separate the stored cards one by one from each other, requiring large-scale equipment such as a vacuum pump. There is a problem in that this requires a larger device, which increases the cost.In addition, with conventional devices, when sending out a card, it sticks to the previous card and the subsequent cards are also sent out together, which is extremely inconvenient. I had a problem.

(Technical Means for Solving the Problems) In view of the above problems, the present invention provides a device that can reliably feed out cards one by one and can be manufactured at low cost with a simple structure. The technical means for this purpose is a stock case 1 which is provided with an outlet 5 at the lower part of the front side, and which stores a large number of cards C stacked and slidable in the vertical direction; The support roller 6 and the rear support roller 7 support the card C in the stock case 1 at both ends with the front edge of the lowermost card C ₁ facing the outlet 5 and the outlet 5. The shutter 8 that opens and closes, the motor M ₁ that drives the rear support roller 7 in forward and reverse rotation, and the lowermost card C ₁ that is elastically deformed in a downward curved shape by the forward rotation of the rear support roller 7 has a fixed amount of deformation. A sensor S ₂ detects that the shutter 8 has been reached and thereby opens the shutter 8 and stops the rotation of the rear support roller 7. The sensor S ₂ detects that the lowest card C ₁ sent out from the delivery port 5 has left the rear support roller 7 and thereby causes the rear support roller 7 to reverse. This is what happens.

(Example) An example of the present invention will be described below based on the drawings.

Figure 1 shows the appearance of a telephone card vending machine. In this vending machine, when a banknote, such as a 1,000 yen bill, is inserted into the banknote slot D, the authenticity of the banknote is checked by a sorting device E. If it is determined that the banknote is genuine, the telephone card C that has been waiting in the card standby section B is sent forward so that its tip protrudes into the card ejection port F. When the telephone card C is pulled out from the card ejection port F, the next telephone card C is transferred by the card feeding device A.
Only one card is sent out to a predetermined position in the card standby section B.

From FIG. 2 onwards, the card dispensing device A and the card standby section B are shown. In these figures, 1 is a stock case for stacking and storing a large number of business card-sized telephone cards C so that they can be slid vertically. A delivery port 5 is provided at the lower part of the front side of the stock case 1 between the lower end surface of the front vertical frames 2, 2 and the upper end surface of the support wall 4, and a gap between the delivery port 5 is provided. is set to about 1.5 times the thickness of one telephone card C.
6 and 7, and a front support roller and a rear support roller that are suspended parallel to each other at the front and rear ends of the lower part of the stock case 1.
The lowermost card C 1 of the telephone cards C stored in the stock case ₁ is supported at both ends with its front edge facing the outlet 5, and the rear support roller 7 is adapted to be driven to rotate in forward and reverse directions by motor _M1 . 8 is a shutter that opens and closes the outlet 5;
It is raised and lowered by a solenoid 9 to perform opening and closing operations. Reference numeral 10 denotes a weight plate made of a metal plate or the like, which is housed in the stock case 1 and presses the telephone card C . . . appropriately from above. S ₁ is telephone card C in stock case 1
A sensor that detects when the remaining amount is low.
It consists of a limit switch, which is operated by the impact of an operating piece 11 that is protruded from the rear end of the weight plate 10 and is slidably guided between the rear vertical frames 3, 3. . _S2 is a sensor consisting of a limit switch for detecting when the deflection of the lowermost telephone card _C1 , which is curved and deformed by the drive of the rear support roller 7, reaches a certain amount, as shown in FIG. The bulge of the lowermost card _C1 , which is curved downward as shown in FIG.

Further, numerals 13 and 14 are feed rollers each consisting of a pair of upper and lower rollers disposed one after the other in the card standby section B, and each lower roller is driven by a motor _M2 . This motor _M2 is also adapted to drive the front support roller 6 of the card feeder A in rotation. S ₃ and S ₄ are

is a guide member.

Next, the operation of the card dispensing device A described above will be explained in conjunction with the operation of the card standby section B in FIGS. 2 and 4.
This will be explained according to FIGS.

First, in the state shown in FIG. 2, card dispensing device A is inactive, but one telephone card _C0 , which has already been dispensed by device A, is waiting in card standby section B. In other words, it is ready for sale at any time. Then, from this state, a bill is inserted from the bill slot D of the vending machine, and when the bill is determined by the sorting device E to be a genuine bill of a predetermined amount, the motor _M2 is activated by the signal. This rotates, and the linked feed rollers 13 and 14 are driven, whereby the waiting telephone card _C0 is sent forward to the position shown by the one-dot chain line in FIG. It is held in a position where it can be taken out from F.

When this telephone card _C0 is taken out as shown in FIG. 4 and the sensor _S3 is turned on, the motor _M1 of the card feeding device A rotates in the normal direction. Note that the outlet 5 is in a closed state by the shutter 8. As the motor _M1 rotates forward, the rear support roller 7, which is interlocked with the motor M1, is driven to rotate in the counterclockwise direction (feeding direction) as shown in FIG.
Therefore, the lowest telephone card _C1 in the stock case 1 has one edge that is connected to the shutter 8.
When the rear side is dragged forward by the rear support roller 7 in a state where it is locked, it bends downward in a curved shape (elastic deformation).

As shown in FIG. 5, when this deflection reaches a certain amount and the operating arm 12 of the sensor _S2 is pressed down by the downwardly bulging portion of the card _C1 , the sensor _S2 operates and the solenoid 9 is energized. , whereby the shutter 8 is lowered and the outlet 5 is opened. At this time, the motor _M1 is simultaneously stopped and the rotation of the rear support roller 7 is stopped. When the outlet 5 is opened by lowering the shutter 8, the lowermost telephone card _C1 , which had been elastically deformed into a curved shape and whose rear end was pressed by the rear support roller 7, is moved. , due to its own elastic restoring force, the outlet 5
, and is pulled out and sent forward by the front feed roller 14, thereby causing the rear roller 5 to
is separated from the bottom card C ₁ and transferred to the next card C ₂ . Card C ₁ inside sensor S ₄
When the sensor S4 passes, the sensor _S4 turns OFF, and the motor _M1 starts rotating in the opposite direction, causing the rear support roller 7 to rotate clockwise as shown in Fig. 6, thereby turning off the next card. A tensile force is applied to C ₂ in the opposite direction to the feeding direction of the previous card C ₁ , thereby causing the subsequent card C ₂ to
I'm trying to prevent it from being dragged along by C ₁ and being sent out with it.

The first card C ₁ is the feed roller 14, sensor S ₄
After passing through the guide member 15, the card is further sent by the front feed roller 13 and enters the sensor _S3 on the exit side of the guide member ₁₅ as shown by the dashed line in FIG. Due to the entry of the tip of _C1 , the sensor _S3 is turned off, and the motor is turned off.
Both M ₁ and motor M ₂ are stopped from rotating, so that card C ₁ is placed in a standby position as shown in FIG. 2 and ready for sale.

In the above-mentioned feeding operation of the card C ₁ , the rear support roller 7 is reversely moved so that the card C ₁ is fed out so as to spring out from the feeding port ₅ .
It is necessary to start immediately after the rear end part leaves the roller 7, and for this purpose, the position of the sensor S ₄ should be set by appropriately considering the length of the card, the position of the rear support roller 7, etc. good. In addition, in order to prevent the rear end of the card C ₂ from falling downward while being curved downward due to the reverse rotation of the rear support roller 7, the rear support roller 7 is A stopper 16 is provided at the rear.

In addition, according to the card vending machine equipped with the card standby part B as in this embodiment, one sellable card is always waiting in front of the card ejection port.
As long as the banknotes are inserted and the OK signal is output, even if card ejection device A malfunctions, at least one card will always come out of the ejection slot as long as there is no malfunction in standby section B. , customers will no longer be inconvenienced because they will no longer have to worry about their card not coming out after putting in money.

(Effect of the invention) The card ejecting device of the present invention does not rely on the suction method using a suction cup like the conventional device, but instead uses the card retrieval device by rotating the rear support roller that is in contact with the lowest card in the stock case in the normal direction. The lowermost card whose front edge is locked by the shutter is elastically deformed into a downward curved shape, and when the amount of deformation reaches a certain amount, the shutter is opened and the card is sent out from the delivery port by its self-restoring force. Because of its structure, it is possible to separate the bottom card from the following cards and reliably send out only that one card.Moreover, the structure is simple and the number of parts is small, making it a small and space-saving device. It has the effect of being able to provide products at low cost.

In addition, in the device of the present invention, the sensor detects when the lowest card, which is sent out from the delivery port due to self-restoring force after being elastically deformed in a downwardly curved shape, has left the rear support roller. The rear support roller is detected and reversed, thereby applying a tensile force in the opposite direction to the feeding direction to the subsequent card, that is, the next card. This avoids the inconvenient situation where the card is dragged along with the previous card and sent out together.

In addition, in the present invention, since the front support member that supports the card at the front end side together with the rear support roller is a roller, the upper surface of the front end of the lowest card to be sent out is in contact with the lower surface of the front end of the following card. Since the lower surface of the front end of the card is in line and rotational contact with the front support roller, the lowermost card can be smoothly and reliably fed out.

Furthermore, according to the present invention, the rear support roller has the function of deforming the lowest card into a curved shape and feeding it out, and the function of applying a tensile force in the opposite direction to the feeding direction to the following card by reversing the roller. As compared with a device in which the rear support roller merely has a feeding function, the structure can be significantly simplified and made more compact.
