Description

[Detailed explanation of the idea] [Industrial application field]

This invention allows various cards inserted through the slot,
Or a card that sends various cards sent by other transport means to the next stage of various card processing devices such as a printing machine or a code reader, or ejects them to the outside of the machine. Regarding the feeding device.

[Conventional technology]

Conventional card feeding devices that feed cards as described above can be roughly divided into magnetic card feeding devices that use a magnet as a driving source and rotate card feeding rubber rollers to feed cards;
There is a motor-type card feeding device that uses a motor as a drive source to rotate a card feeding rubber roller to feed cards.

[Problem that the invention attempts to solve]

Of the above-mentioned two card feeding devices, the magnetic card feeding device uses a magnet to operate the feeding pawl to feed the ratchet wheel one tooth at a time, and feeds and rotates a rubber roller coaxially attached to the ratchet wheel. , and a tension roller. Therefore, in order to construct the device, in addition to the above-mentioned magnet, feed pawl, ratchet wheel, rubber roller, and tension roller, parts such as a detent to prevent the above-mentioned ratchet wheel from reversing are required. There are many points and the configuration is complicated, and manufacturing and assembly are troublesome and relatively expensive.The feed pawl only feeds the ratchet wheel by one tooth (one pitch) for each on/off operation of the magnet. Because of this, there was a problem that card feeding was intermittent and the feeding speed was slow. Further, the above-mentioned motor-type card feeding device has a structure in which the rotation of the motor is transmitted through a drive gear to feed cards between a rubber roller and a tension roller that are coaxially attached to a reduction gear. Similar to the type card feeding device, it has many parts, has a complicated structure, and is expensive.In addition, since the motor is used as the drive source, overrun occurs, making it difficult to feed cards to a specified length. I had a problem.

[Means to solve the problem]

Therefore, the present invention was proposed to solve the above-mentioned problems, and its purpose is to have a simple structure, a small number of parts, and to be very economical as it can be manufactured at a very low cost. Another object of the present invention is to provide a card feeding device that has a high feeding speed considering that it uses a magnet as a driving source, and can reliably feed cards of a predetermined length without the problem of overrun. In the invention, according to the on/off operation of a solenoid located in the middle,
At the lower ends of the left and right leg rods, each of which is configured to perform an amplitude movement relative to the card feeding direction,
The objects of the above-mentioned inventions are achieved by respectively attaching feeding pawls that feed the card only when the leg rods are moving in the card feeding direction.

[Effect]

According to the card feeding device of the present invention configured as described above, when the solenoid is energized and the left and right leg rods are sucked inward, first, one of the leg rods (card feeding If the direction is to the left, the feed claw attached to the right leg lever will feed the card. Next, when the solenoid is deenergized and the left and right leg levers return to their original positions, the feed pawl attached to the other leg lever that moves back in the card feeding direction feeds the card, which turns the solenoid on and off. Card feeding will be performed twice each time .

【Example】

Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 showing a side view of a card feeding device according to the present invention, FIG. 2 showing a front view thereof, and
In Fig. 3, which shows the state in which the solenoids are energized (turned on) and both leg levers are being operated under suction, the left and right leg levers 1a and 1b are shown as 1 on each side. This leg member 1 is vertically installed and integrally formed into an inverted U-shaped substantially tuning fork shape. This leg member 1 is constructed by, for example, bending a plate spring material into an inverted U-shape. Both leg rods 1a and 1b are fixed to a support arm 3 which is horizontally connected to the upper end thereof, with the legs hanging down toward a platen 4 provided on a card C feeding path. A solenoid 5 is attached to the mounting frame 2 using a fixing member 6 so as to be located between the left and right leg levers 1a and 1b.Both poles 5N and 5S of this solenoid 5 are located between the left and right leg levers 1a and 1b. The solenoid 5 is protruded toward the inner surface in the middle, and when the solenoid 5 is energized by electricity, both leg rods 1a,
1b is designed to be sucked inward. 7a and 7b are feed claws rotatably attached to the lower ends of the left and right leg rods 1a and 1b using shafts 8a and 8b, and as in the illustrated embodiment, the card C is In the case of a device that is fed leftward in the figure, the lower left end portions of both feed claws 7a, 7b form acute-angled claw tips 7a1, 7b1, and each leg rod 1
When the fingers a and 1b operate in the feeding direction of the card C, that is, in the left direction in the drawing, the toe portions 7a1 and 7b1
The card C lightly bites into the upper surface of the card C, thereby allowing the card C on the platen 4 to be sent to the left in the drawing. Further, 9a, 9b are recesses formed in the upper edges of the above-mentioned two feed claws 7a, 7b, and these recesses 9a, 9
The left protruding surfaces 9a1 and 9b1 in b have both leg rods 1
The bent lower ends of the leaf springs 10a, 10b attached to the springs 10a, 1b are brought into elastic contact, and the feed claws 7a, 7b are constantly biased in the counterclockwise direction in the drawing about the shafts 8a, 8b, The portions 7a1 and 7b1 are pressed against the card C surface. According to the card feeding device according to the present invention configured as described above, when the solenoid 5 is energized and energized in the state shown in FIG. Operate. At this time, the feed pawl 7a attached to the left leg rod 1a, which is suction operated in the opposite direction to the card C feed direction (left direction in the drawing), slides the pawl portion 7a1 on the card C surface, and , resists the leaf spring 10a and rotates in the clockwise direction in the drawing about the shaft 8a as a fulcrum. On the other hand, the toe portion 7b1 of the feed claw 7b attached to the right leg 1a bites into the surface of the card C, and the card C is sent to the left in accordance with the suction operation of the leg 1a. When the electricity is turned off and the solenoid 5 is deenergized, the left leg levers 1a and 1b, which have been suction operated, return to the original position shown in FIG. 2 by their own elasticity and rotate. Tip part 7a1 of feed claw 7a attached to 1a
bites into the card C side and sends card C to the left. Therefore, if the solenoid 5 is turned on and off repeatedly to vibrate both leg rods 1a and 1b in the card C feeding direction, the card C will be continuously fed to the next printing machine or the card code. It is sent into the reader, etc., or discharged to the outside of the aircraft. Note that the feeding speed of the card C can be freely controlled by the height (voltage) of the pulse applied to the solenoid 5 and the speed (hertz) of the pulse.

【effect】

Since the card feeding device according to the present invention is as described above, by repeatedly turning on and off the solenoid to vibrate the left and right leg levers, the feeding claw can feed the card. In this invention, the two feeding claws attached to the left and right leg levers feed the card whether the solenoid is on or off, so compared to the conventional magnetic card feeding device that feeds the card only when the solenoid is on or off. This has the advantage of being able to feed cards smoothly and at high speed, and the amount of card feeding can be adjusted accurately by controlling the on/off of the solenoid, so it is not like a conventional motorized card feeding device. There is no need to worry about overruns, and the entire device can be constructed with an extremely small number of parts such as the leg rod, solenoid, and feed pawl, making it economical and easy to manufacture and assemble. It also has many practical advantages, and its practical value is enormous.
