DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card supply device for automatically cutting out cards stored in a magazine one by one from the top of the magazine.

[0002]

2. Description of the Related Art A conventional apparatus of this kind is disclosed in Japanese Utility Model Laid-Open No. 60-870.
No. 60 publication. Here, a group of stacked cards is pushed up by an elevating mechanism, and the uppermost card is fed horizontally by a feed belt and a pair of feed rollers. The elevating mechanism therefor was constituted by a push-up table for supporting a group of cards, a screw shaft for raising and lowering the push-up table via a female screw body, a transmission mechanism for transmitting the power of the motor to the screw shaft, and the like. The motor is driven intermittently every time a predetermined number of cards are sent out.

[0003]

In the prior art in which cards are fed intermittently while a group of cards are pushed up intermittently, the contact pressure between the feed belt and the uppermost card contacting the feed belt changes periodically. Card feeding cannot be performed correctly. For example, when the contact pressure is high, a plurality of cards are sent out at the same time, and when the contact pressure is low, slippage occurs and cards cannot be sent out one by one. In particular, there has been a problem in cutting out cards one by one in units of several at a time. In order to avoid such a situation, it is necessary to lower the belt or roller that kicks out the card in accordance with the amount of the reduced card. However, this complicates the mechanism. It is sufficient that the card group can be pushed up by the thickness of the card every time one card is sent out. However, considering the transmission path from the motor to the screw shaft due to the small card thickness, it is impossible to obtain the required accuracy. Even if technically possible, it is unavoidable that production costs increase.

[0004] Therefore, an object of the present invention is to keep the contact pressure between the feed roller and the uppermost card constant at the time of sending out cards one by one from the upper part of the magazine, and to carry out the card accurately and simultaneously. An object of the present invention is to provide a card supply device which can realize the simplification of the structure of the entire apparatus and reduce the manufacturing cost.

Port provided in the slide frame 11 and the table 4
Whether the pressing plate 40 of the lift body 6 is downward through the 11a and 4a
Can enter the magazine 3. In use, a group of cards 5 in the magazine 3 is pushed up by the pressing plate 40 of the lift body 6, and the uppermost card 5 is in contact with the feed roller 22 of the card sending mechanism 2 at a predetermined pressure. . That is, the entire weight of the group of cards 5 is supported by the lift body 6 via the tension of the extension coil spring 7. When the cards 5 are taken out one by one from this state, the total weight supported by the lift body 6 is reduced by the amount of the cards 5 sent out. On the other hand, with the sending of the card 5, the lift body 6
And the tension of the tension coil spring 7 tends to decrease. However, since the amount of change in the tension of the spring 7 due to the card delivery and the amount of weight reduction of the group of cards 5 are substantially matched, the contact pressure between the uppermost card 5 and the feed roller 22 should be as small as possible. It will be constant.

When the idler wheel 47 is rotatably provided on the upper portion of the machine frame 1 and the tension coil spring 7 is wound around the idler wheel 47 in an inverted U shape, the total length of the spring 7 can be increased. Even if the number of cards 5 in the magazine 3 decreases, the spring 7
And the pressing force of the card 5 against the feed roller 22 can be made as constant as possible, and the vertical height of the machine frame 1 can be reduced. The pressing plate 40 of the elevating shaft 39 receives the group of cards 5 in the magazine 3 in a forward rising and inclined posture. Therefore, the uppermost card 5 is received in a front contact state with the lower surface of the guide wall 23 whose front end is in a horizontal position, and the front edge of the card 5 faces the gap g between the guide wall 23 and the regulating wall 24 from obliquely below. Then, the cards 5 are sequentially cut out one by one by friction with the feed roller 22.

Is pushed up by the lift body 6. In addition, the amount of change in the tension of the tension coil spring 7 accompanying the card delivery and the amount of weight reduction of the group of cards 5 are substantially matched so that the uppermost card 5 always comes into contact with the feed roller 22 at a constant pressure. did.
Therefore, even when several cards 5 are sent out at one time, the feed roller 22 can maintain a constant contact pressure so that the cards 5 can be cut out one by one without fail.

[0010] Since a group of cards 5 is pushed up by the spring 7 and the card is supplied while the uppermost card 5 is constantly pressed against the feed roller 22, the card is supplied compared with a conventional lifting mechanism using a screw as a mechanism element. The structure can be simplified. further,

Although not shown, the upper surface of the opening of the magazine 3 is provided with a lid with a handle for opening and closing the opening, and this lid is removed during use. The magazine 3 is supported on the table 4 in a portrait orientation. The table 4 protrudes horizontally from the machine frame 1 toward the front, and a rectangular slide frame 11 is placed on a plate surface surrounded by a peripheral wall provided upright at three peripheral edges thereof. The slide frame 11 can be slid in the front-rear direction while being guided by guide grooves 12 formed in the left and right peripheral wall portions, and a pin 13 for opening and operating the shutter plate 10 is protruded toward the front end. As shown in FIG. 2, openings 11a and 4a that allow the lift body 6 to pass therethrough are opened in the plate surfaces of the slide frame 11 and the table 4, respectively.

As shown by the dashed line in FIG.
When the magazine 3 is placed on the shutter 1, the pins 13 engage with the shutter plate 10. In this state, the magazine 3 is pushed toward the machine frame 1, and the lower end thereof is inserted into the opening 11 a of the slide frame 11.
When it is positioned above, the shutter plate 10 is relatively pulled out of the magazine 3, and the lower opening of the magazine 3 is opened. At this time, a part of the upper edge of the magazine 3 fits into the guide groove 28 provided in the card sending mechanism 2. Next, when the magazine 3 and the slide frame 11 are further pushed in the direction of arrow a until the slide frame 11 contacts the machine frame 1,
The magazine 3 can be correctly positioned with respect to the upper card sending mechanism 2 and the lower lift body 6. The lower ends of a group of cards 5 in the magazine 3 are always received and supported by a pair of left and right holding claws, and the card 5 does not fall out of the magazine 3 even when the shutter plate 10 is opened.

In order to hold and fix the magazine 3 positioned and loaded as described above, the magazine holder 15 is attached to the machine frame 1.
Having. In FIG. 3, the holder 15 has a U-shaped guide frame 16 fixed to the machine frame 1, a shaft 17 that is supported by the guide frame 16 so as to be able to move back and forth, and protrudes forward. And a holding lever 19 fixed to the front end side of a shaft 17 protruding from the guide frame 16 and an operation knob 20. In the holding state, the holding lever 19 contacts the front wall of the magazine 3 to prevent the magazine 3 from moving forward. When the operation knob 20 is turned against the compression coil spring 18 while the operation knob 20 is pulled, the movement restriction by the holding lever 19 can be released.

In FIG. 3, a card sending mechanism 2 includes a feed roller 22 disposed facing an upper opening of the magazine 3,
A lateral guiding wall 23 disposed adjacent to the front side of the feed roller 22, a vertical regulating wall 24 disposed below the guiding wall 23 to prevent the sending of a second or less card,
A pair of upper and lower supply rollers 25 and 26 disposed in front of the two walls 23 and 24, a drive mechanism for rotating and driving the feed roller 22 and the upper supply roller 25, and 2
These members are incorporated in a U-shaped frame 27 in plan view. Frame 2
A guide groove 28 for the magazine 3 is provided at the lower inner edge of the magazine 7. A gap g corresponding to the thickness of one card 5 is provided between the guide wall 23 and the regulation wall 24 as shown in FIG.

As shown in FIG. 4, the above driving mechanism uses a motor 29 as a driving source, and a driving gear 30 fixed to the output shaft thereof and driven gears 31 and 32 fixed to the roller shafts of the rollers 22 and 25. The rotational power is transmitted via the. However,
Each gear 30 is transmitted so that the power is transmitted to the supply roller 25 in a speed-up state and to the roller shaft of the feed roller 22 in a deceleration state.
・ Gear ratios of 31 and 32 are defined. Further, a differential mechanism is provided between the feed roller 22 and the driven gear 31 therefor.

4 and 5, the driven gear 31 is rotatably supported by a roller shaft of the feed roller 22 via a bearing 33. A differential gear 34 in the form of a missing gear is arranged adjacent to the driven gear 31 and fixed to the roller shaft. A roller 36 is attached to the inner surface of the driven gear 31 corresponding to the step 35 of the differential wheel 34. Thus, the differential mechanism transmits the rotational power of the driven gear 31 to the feed roller 22 via the roller 36 and the differential wheel 34.

As shown in FIG. 2, the card sending mechanism 2 has a reflective card sensor 51 disposed on the inner surface of the frame 27 facing the upper opening of the magazine 3, and detects the presence or absence of the card 5 in the magazine 3. Further, the supply rollers 25 and 2
A transmission type card sensor 52 is arranged facing the card locus sent out from the card 6 to check the sending of the card 5 and to detect the quantity of the card 5 and reflect these detection signals in device control. In FIG. 4, rollers 53 arranged on the inner wall of the frame 27 on the machine frame 1 side prevent the cards 5 group pushed up by the lift body 6 from coming out above and incline the posture of the cards 5 upward. It is.

In FIG. 1, a lift body 6 includes a pair of left and right elevating shafts 39 movably supported on the machine frame 1 via bearings 38, and an L-shaped pressing plate 40 fixed to the upper end of the elevating shaft 39. And an operating lever 4 fixed to the lower end of the elevating shaft 39.
1 and a connection frame 42, and a hook 43 fixed to the lower surface of the connection frame 42. The rear end of the operation lever 41 projects to the rear of the machine frame via a vertical groove 44 provided in the machine frame 1 in a penetrating manner. In order to temporarily fix the operation lever 41 at the lower end of the vertical groove 44 when replacing the magazine 3, a holder 50 corresponding to the hook 43 is provided below the vertical groove 44.

A case 46 having a U-shaped cross section is fixed to the back of the machine frame 1 so that the group of cards 5 can be pushed up by the lift body 6 toward the upper card sending mechanism 2. Accommodates a tension coil spring 7.
That is, the idler wheel 47 is rotatably supported at the upper end in the case 46 so as to freely rotate. An intermediate portion of the tension coil spring 7 is wound around the idler wheel 47 in an inverted U-shape, and one end of the spring 7 is connected to a lower end of the elevating shaft 39, specifically, a rear end of the operation lever 41. And the other end of the spring 7 is connected to the connection fitting 4.
8 and connected to the spring holder 49. As shown in FIG. 7, the fixed position of the spring receiver 49 can be changed to an arbitrary vertical position along a vertical groove 54 provided in the case 46.

As shown in FIG. 8, the tension of the lift spring 7 is
The amount of change in the tension of the tension coil spring 7 due to the upward movement of the lift body 6 at the time of sending out the card and the amount of weight reduction of the group of cards 5 due to the sending of the card are set to be substantially the same. That is, the weight of the card in the magazine 3 is always offset, and the card 5 pushed up by the lift body 6 is brought into contact with the feed roller 22 at a constant contact pressure.

The tension coil spring 7 capable of satisfying the above requirements
It is necessary to consider the spring life when forming. If the overall length of the spring is short, or if the wire diameter and the coil diameter are extremely small, the lift spring 7 elongates and deforms early,
The desired tensile properties are lost. Therefore, the entire length of the tension coil spring 7 is made as long as possible. However, due to space restrictions, the idler wheel 47 is interposed midway to
Was wound in an inverted U-shape. In this example, 1.5 g per sheet
When 1,000 cards 5 are inserted into one magazine 3, the wire diameter of the tension coil spring 7 is 1.6 mm, the coil outer diameter in the free state and the effective spring total length are 16 mm and 2 mm, respectively.
The initial tension of the spring 7 was adjusted so that the contact pressure between the card 5 and the feed roller 22 when the card supply was started was 0.6 kgf / cm ² .

Next, the movement of the card sending mechanism 2 will be described. The card sending can be started by moving the lift body 6 into the magazine 3 and pressing a group of cards 5 against the feed roller 22 by the pressing plate 40 thereof. At this time, the card group is pushed up by the pressing plate 40 having an L-shaped cross section, and the projection 40a protrudes upward at the front end, so that one group of the cards 5 is in a front-up inclined posture. The card 5 group may be received and supported by the pressing plate 40 in the forwardly inclined position, and the upper surface of the pressing plate 40 may be formed to be entirely inclined, or the flat pressing plate 4 may be formed.
0 It may be fixed to the elevating shaft 39 so that the upper surface is inclined.

Thus, as shown in FIG. 5, the uppermost card 5 has its front end received by the lower surface of the guide wall 23,
The card 5 bends along the lower peripheral surface of the feed roller 22 which is located slightly behind and behind the guide wall 23, and the card 5 adopts a forwardly inclined posture. Then, the front edge of the card 5 faces the gap g between the guide wall 23 and the regulating wall 24 from obliquely below.

When the motor 29 is started in this state, the feed roller 22 is driven to rotate via the differential mechanism, and the card 5 is rotated.
Are cut out one by one from the gap g. When the card 5 reaches the pair of supply rollers 25 and 26, both rollers 25 and 26 having a higher rotation speed than the feed roller 22.
The card 5 is quickly sent out. At this time, the card transfer speed is higher than the peripheral speed of the feed roller 22, and the card 5
Is in contact with the feed roller 22 at a predetermined contact pressure. Therefore, the feed roller 22 rotates along with the card 5, and accordingly, the differential wheel 34 rotates ahead of the roller 36 as shown in FIG.

Waiting for the rear end of the card 5 to pass through the peripheral surface of the feed roller 22, the card 5 located on the uppermost surface comes into circumscribed contact with the feed roller 22 at a predetermined contact pressure, and the frictional force is applied. Thus, inertial rotation of the feed roller 22 is prevented. After this, the supply roller 25 and the roller 36 continue to rotate, and the card 5 is sent out from the supply roller 25 and the trailing end is detected by the card sensor 52.
Is stopped and braked. Thereby, the roller 36 and the differential wheel 34 return to the initial state of FIG.

FIG. 9 shows another embodiment of the card sending mechanism. In this embodiment, an electromagnetic clutch 56 is provided between the driven gear 31 and the roller shaft 22a of the feed roller 22 instead of the differential mechanism. The electromagnetic clutch 56 is connected to the roller shaft 22a.
, An armature 58 rotatably supported with respect to the output hub 57, a coil holder 60 having an electromagnetic coil 59 for suctioning the armature 58, and the like, which is built in the armature 58. Using the coil spring 61 as a transmission element, the power of the driven gear 31 is output to the output hub 57 via the coil spring 61 only when the armature 58 is attracted to the coil holder 60 side. At this time, the coil diameter of the coil spring 61 decreases, and the coil spring 61 is simultaneously wound around both the boss portions of the driven gear 31 and the output hub 57. The driven gear 31 is rotatably supported by the output hub 57. The electromagnetic coil 59 is excited at the same time when the motor 29 is started, and is demagnetized at the same time when the card sensor 52 detects the leading end of the card 5.

The tension coil spring 7 may be composed of a plurality of pieces, and may be arranged on the front side of the machine frame 1.
