Description

[Detailed explanation of the invention] This invention is based on plate-like objects such as stacked cards,
For example, the present invention relates to a device for dispensing plate-shaped objects such as credit cards, metal plates, non-metal plates, etc., one by one by a picker that reciprocates, and particularly relates to the operation of the picker.

In recent years, credit card processing machines, ticket issuing processing machines, etc. have been equipped with card feeding devices that stack card-like paper sheets and take out the paper sheets one by one from the stacked area, and these machines perform a predetermined function. Many devices are installed and in use.

In addition, for example, a material supply device that stacks aluminum plates cut to a regular length and feeds the aluminum plates one by one from the stacked portion to supply the material to, for example, a process for producing parts for electrical appliances, or a material supply device with a similar configuration. 2. Description of the Related Art Delivery devices for so-called plate-shaped objects such as cards play an important role in various fields, such as material supply devices for processing plywood for building materials.

These delivery mechanisms include those that use friction such as rollers and belts, and those that attract needles and hooks, but these mechanisms may cause harmful damage to the delivered object. Furthermore, as a whole system, there are various ways of stacking and delivery, such as stacking the objects vertically and sending out the one at the upper or lower end, or stacking them horizontally and sending out the one at the end first. However, in many cases, it is necessary to select and adopt them depending on the aspect, which is not very practical.

As improvements to this, there are methods that use gas pressure such as air and methods that push one end with a picker, but methods that use gas pressure are unsuitable for areas with a lot of dust, so the picker method has traditionally been widely used. There is. However, even in this picker method, there is a problem in that the object to be sent is damaged.

The present invention was devised to eliminate the drawbacks of the conventional device using the picker method, and will be mainly described below with reference to a card dispensing device such as a credit card processing machine or a ticket issuing/processing machine.

In recent years, in order to increase the amount of information and to reduce the cost per card, there has been a tendency to use the back side of the card to add information. Examples include the articles of incorporation and precautions for use shown on the back of credit cards and commuter passes, as well as optical and magnetic information. In these cards in which information is recorded on both the front and back sides, even the back side must not be damaged.

FIG. 1 is a side sectional view of an example of a conventional card dispensing device, with FIG. 1 a showing the state before dispensing, and FIG. 1 b showing the state immediately after dispensing.

A large number of cards 3 are stored in the storage box 1 as a hopper, which is composed of four side walls 11 and a bottom plate 12.
1, 32, 33, . . . are stacked in order, and are pressed in the direction of the bottom plate 12 by a pressing member 4 from the rearmost portion thereof as shown by an arrow Z.

The bottom plate 12 of the storage box 1 has an opening groove having a width sufficient to allow the claw portion 21 of the picker 2, which reciprocates in the direction of the arrow X, which is the feeding direction of the stored cards, and the direction of the arrow X', which is the opposite direction, to come into contact with the cards. It is provided. Further, at the lowest part of the side wall 11 of the storage box 1 on the card delivery side, a slit 13 is provided with a width that allows one card to pass through but does not allow two cards to pass through at the same time.

Before the start of the card feeding operation, the picker 2, whose claw portion 21 is placed on standby at a location where it is removed from the storage box 1 as shown in FIG. shaft 22
It is moved in the direction of the arrow X using the fulcrum as the fulcrum. At this time, the claw portion 21 is configured to hang on the first card 31 but not on any other cards.

Therefore, when the picker 2 is moved in the direction of the arrow X, only the first card 31 is moved in the direction of the arrow X by the claw portion 21, and is caused to protrude from the slit 13 of the side wall 11 as shown in FIG. 1b. It will be done.

In this way, among the many stacked cards stored in the storage box 1, only the card 31 closest to the bottom plate 12 is separated and protruded out of the storage box 1. The protruding portion of this card 31 is grasped and pulled out by another device not shown.

On the other hand, after the picker 2 finishes its forward movement in the direction of the arrow X to send out the card 31, it begins a return movement in the direction of the arrow Because it is made to stick out,
Cards other than card 31 are pressed against arrow Z by pressing body 4.
direction, that is, to the bottom plate 12 side,
In the part where card 31 was removed, card 3
2 approaches the direction of the bottom plate 12 and is inclined as shown in FIG. 1b.

When the picker 2 moves back in the direction of arrow X' in this state, the claw portion 21 moves while contacting the lower surface of the card 32. That is, in the conventional card dispensing device of this type, the relative position of the claw portion 21 of the picker 2 with respect to the bottom plate 12 as described above is such that the card closest to the bottom plate is hooked, but the other cards are not hooked. There is a method in which the picker 2 is fixed in position and does not move in either the arrow Z direction or the arrow Z' direction. The height of the card is sufficient to send out one card, but does not overlap with two cards, and the structure is movable in the directions of arrows Z' and Z against the spring force. However, in both methods, Pitzka 2
When the card moves back in the direction of arrow X', the claw portion 21 moves while touching the next card, that is, the card 32 in this example, and reaches the standby position for feeding the next card 32 shown in FIG. 1a. It had a structure that made it seem like it would come back.

As described above, the conventional card dispensing device that contacts the stacked card surfaces during the return movement of the picker 2 not only causes the problem of wear of the claw portion 21 of the picker 2, but also causes unexpected damage to the card surface. This is a serious drawback for recent card dispensing devices, which have to be issued with information on both the front and back sides as described above.

This idea was made in view of the above circumstances.
The purpose is to provide a device for dispensing plate-like objects such as cards that eliminates the above-mentioned conventional problems, greatly improves its reliability and durability in practice, and exhibits correct functions. Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 2 is a side sectional view of one embodiment of the card dispensing device according to the present invention, FIG. 2 a shows the state before dispensing, and FIG. 2 b shows the state immediately after dispensing. Reference numerals indicate parts that are the same or have the same function.

In the card dispensing device according to the present invention, the picker 2 is always pressed in the direction of the arrow Z', that is, toward the hopper, by a spring (not shown), and the height of the claw portion 21 is sufficient for dispensing one card. It is structured so that it does not overlap the two sheets. Furthermore, pins 24 are provided so as to protrude from both sides of the picker 2, and on both sides of the main body of the picker 2, the pressing force of the picker 2 toward the hopper side is received by the back surface during the return movement of the picker 2. A holding plate 5 is provided for this purpose, and the length of this holding plate 5 corresponds to the reciprocating distance of the picker 2.

Figure 3a is an enlarged detailed view of the dot-dash line circle A in Figure 2a to show the relative positions of the storage box, picker, and presser plate, and Figure 3b is an enlarged view of the area indicated by the arrow Z in Figure 3a. FIG.

A pin 2 protruding from the picker 2 between the bottom plate 12
A presser plate 5 is separated by a space large enough for 4 to freely pass through.
are provided on both sides of Pitzka 2. During the movement of the picker 2 in the direction of the arrow X', that is, during the backward movement, the pin 24 of the picker 2, which has moved while being pressed against the back surface 51 of the holding plate 5, is moved by a force in the direction of the arrow Z' caused by a spring, etc. (not shown). , since the presser plate 5 disappears at the end of the return movement, the bottom plate 1 is moved along an arc 52a that is in contact with the end surface 52 of the presser plate 5 and centered on the shaft 22.
2, the picker 2 passes through the opening groove 14 provided in the bottom plate 12 and comes to rest in contact with the card 31 stacked closest to the bottom plate 12. In this standby position of the picker 2, the claw portion 21 is usually slightly removed from the card end.

When the picker 2 moves forward in the X direction from this standby position, the presser plate 5 has no effect on the movement.

Fig. 3c is a detailed view showing the state in which the picker starts forward movement in response to a card feed command and the claw part contacts the card, and the height of the claw part 21 of the picker 2 is set not to exceed the thickness of one card. Since the card 31 is configured as shown in FIG. At this time, the surface 53 of the presser plate 5 does not come into contact with any part of the picker 2, especially the pin 24.

As shown in Figure 2b, the card 3 closest to the bottom plate
1 is pushed out from the slit 13 of the storage box 1, and the other cards 32, 33... are all pushed out from the side wall 11.
It stays in storage box 1 because it is blocked by. Therefore, the claw portion 21 is adjusted while taking the width of the picker 2 into consideration so that the end portion of the card is not damaged even if the card 31 is pushed out against the frictional force between the card 31 and the card 32 and the bottom plate 12.
It is necessary to keep the height of the card sufficient so that it does not exceed the thickness of the card.

When the card is sent out, the pin 24 of the picker 2 enters the picker moving section. The picker moving part is a part that uses the moving force of the picker 2 in the forward direction to move the pin 24 toward the back surface 51 side of the presser plate 5. The picker moving unit 6 shown in FIG.

FIG. 4 is a detailed diagram of the picker moving part in this embodiment, and FIGS. 4a to 4e sequentially show state changes according to the time flow of picker movement, and FIG. 4f is a plan view of the state shown in FIG. 4d viewed from the direction of arrow Z'.

The picker moving part 6 is composed of a slope plate 61, a lever 62, a pin 63, etc.
1' is given a slope that pushes back the pin 24 of the picker 2 moving in the direction of arrow X, that is, the forward direction, in the direction of arrow Z, that is, in the direction away from the bottom plate 12. One end of the lever 62 is rotatably supported by a pin 63 at the end of the presser plate 5.
The other end is formed obliquely so as to come into close contact with the slope 61' of the slope plate 61, and the lever 62 is pressed in the direction of arrow Z' by a spring or the like (not shown). In this way, centering on the pin 63, the other end is connected to the slope plate 6.
In the state where the lever 62 is rotationally pressed against the slope 61' of 1, the back surface 51 of the holding plate 5 and the lever
The rear surface 62'' of the slope plate 61 and the rear surface 61'' of the slope plate 61 are
They are configured to be on the same plane within the range of manufacturing errors, and similarly, the surface 53 of the presser plate 5 and the surface 62' of the lever 62 are configured to be on the same plane within the range of manufacturing errors.

FIG. 4a shows the picker 2 using its claw portion 21 to send out the card 31 by forward movement in the direction of the arrow X, and the pin 24 just coming into contact with the slope 61' of the slope plate 61. The picker 2 further moves slightly in the X direction, but when moving further in the X direction, the pin 24 is displaced in the Z direction against the pressing force of a spring or the like in the Z' direction.

FIG. 4b shows the claw portion 21 just coming off the card 31 as the pin 24 is displaced in the direction of arrow Z. As the pin 24 is displaced, it comes into contact with the surface 62' of the lever 62, and thereafter the lever 62 is also displaced, and its tip is displaced along an arc 62a centered on the pin 63. FIG. 4b is also a partially enlarged view of FIG. 2b.

FIG. 4c shows a state in which the picker 2 further moves in the direction of arrow X, the pin 24 moves further in the direction of arrow Z, and the claw part 21 is completely separated from the bottom plate 12 of the storage box 1. ing. When the picker 2 moves further in the direction of arrow It is brought into close contact with the slope 61' of 61.

FIG. 4d shows the picker 2 reaching the final end of its forward movement, that is, its movement in the direction of arrow X.
The pin 24 has also reached its extreme position in the direction of the arrow X, and the slope plate 61 is configured so that the pin 24 does not come off the back surface 61' even at this position. When the picker 2 has finished its forward movement in this way, the pin 24 is attached to the back surface 61' of the slope plate 61 by the arrow.
It is pressed in the Z' direction, and the back surface 62'' of the lever 62 and the back surface 51 of the presser plate 5 are aligned on substantially the same plane as this surface.

Figure 4e shows Pitzka 2 making a backward movement, that is, the arrow
This is a diagram showing the state immediately after starting movement in the X′ direction.
As mentioned above, the back surface 61'' of the slope plate 61 and the back surface 62'' of the lever 62 are almost on the same plane as the back surface 51 of the presser plate 5, so while the pin 24 is pressed against these back surfaces, the picker 2 is pressed against its claws. The portion 21 can perform a return movement without contacting the next card 32.

In this way, the picker 2 continues its backward movement in the direction of the arrow X', stopping at the position described with reference to FIG. 3a and waiting in preparation for the next delivery operation. Note that the card 31 that has been projected from the slit 13 to the outside of the storage box 1 is grasped by the protruding portion and pulled out by another device (not shown) before the next card sending command is issued. The timing of this withdrawal may be any time period from when the card is ejected by the picker 2 to when the next card sending command is issued.

Now, if we look again at the operation of the conventional card feeding device shown in FIG. When the picker 2 finishes its forward movement, that is, the movement in the X direction, the ends of the card groups 32, 33, . 4, but as the picker 2 makes a backward movement, that is, a movement in the direction of the arrow X', its claw portion 21 pushes it back again in the direction of the arrow Z'. When the picker 2 further advances in the direction of the arrow X' and the claw part 21 comes off the card part, the ends of the card groups 32, 33 on the opposite side to the slit 13 are again pressed in the direction of the arrow Z, that is, toward the bottom plate 12 by the pressing body 4. Ru.

In other words, the card groups 32, 33, etc., the pressing body 4, etc. make unnecessary see-saw movements within the storage box 1.
This is true not only in the case of a method in which the position of the picker 2 in the direction of the arrow Z is fixed, but also in a method in which the position of the picker 2 in the direction of the arrow Z' is pressed by a spring or the like. In this case, this wasteful seesaw movement is disappearing.

That is, as explained in detail in FIGS. 2 to 4, when the card 31 closest to the bottom plate is partially pushed out of the slit 13 by the picker 2, the card 31 to be sent out next and the pressing body 4 are removed. The entire laminate is attached to the end of the bottom plate 1 on the opposite side of the slit 13.
The card 3 is moved to the 2nd side and then transferred to another device (not shown), such as a conveying device for sending the card to the next process.
When the picker 1 is pulled out by grasping the protrusion 1, the end of the slit 13 side of the stack moves correctly toward the bottom plate 12, and there is no extra movement accompanying the return movement of the picker 2.

Cards handled by card devices such as credit card processing machines and ticket issuing processing machines are often made of paper or plastic, and these materials generally store electrostatic energy depending on the environment, or are used to make cards. Due to the entanglement of end fibers during processing, the ability to separate each leaf of the card may be significantly reduced.

Furthermore, for example, in the case of the aluminum plate mentioned above, there is a phenomenon in which the end faces get entangled due to burrs during processing, and the same can be said of other materials.

Although it is thought that the seesaw movement of the cards and the pressing body in the storage box 1 improves the separation function of each card, in reality, it is caused by electrostatic energy generated in the cards, energy from entanglement of end face fibers, etc. However, each leaf is not uniform, and only the weak points are separated due to the strength and weakness, and the desired separation of each leaf cannot be expected. There was a problem in that it interfered with the inner surface and could not be moved correctly in the direction of the arrow X by the pressing body 4, causing it to malfunction.

In order to overcome this drawback, measures have been taken such as increasing the pressing force on the pressing body 4, devising the shape of the inner surface of the side wall 11 of the storage box 1, and reducing the coefficient of friction. However, these measures not only increase the cost, but also do not solve problems such as damage to the next card and wear of the picker 2. In addition, increasing the pressing force of the pressing body 4 does not cause damage to the card at the time of feeding. It can be said that the countermeasures created a vicious cycle, leading to an increase in the pressing force of the card, increasing the possibility of damage to the card by picks, and the problem became more complex and wide-ranging and remained unresolved.

In order to fundamentally solve this conventional drawback, the present invention is designed to separate the picker from the object to be delivered during the backward movement, and press it against the object to be delivered during the forward movement of the picker 2, and then terminate the forward movement. The device is equipped with a picker moving part that uses the kinetic force to move the pressing force to the back side of the presser plate 5 during the return movement, and the one shown in FIG. It is sufficient if the pin 24 can be moved in the Z direction to the back of the holding plate 5 by using the moving force of the pin 2 in the X direction to overcome the pressing force of the picker 2 in the Z' direction.
Various other mechanisms are conceivable for the mechanism of the picker moving section.

FIG. 5 is an enlarged side view of another embodiment of the picker moving part, and the pin 24 of the picker is shown in FIG.
5A to 5C, and the same reference numerals as in FIGS. 1 to 4 indicate the same parts or parts having the same functions.

In this embodiment, the picker moving part 7 provided at the terminal end of the presser plate 5 includes a special gear 71 rotatably supported by a shaft 72 and a shaft 74 provided to prevent reverse rotation of the special gear 71. The ratchet 73 is supported by the ratchet 73.

As shown in FIG. 5a, the pin 24, which has advanced in the forward direction of the arrow X direction without interfering with the surface 53 of the presser plate 5, is rotatable only in the arrow W direction about the shaft 72 by the ratchet 73. After contacting the tooth surface of the special gear 71, a part of the forward motion force is divided into a force in the direction of arrow Z, and the gear 2
It is also moved in the direction of arrow Z against the pressing force of . As the pin 24 further advances in the direction of arrow X, the pin 24 moves the special gear 71 in the direction of arrow W, as shown in FIG.
further move in the direction of arrow Z while rotating in the direction. When the pin 24 finishes its forward movement and starts moving in the backward direction, the special gear 71 is moved by the pressing force of the picker 2.
However, the ratchet 73 prevents the pin 24 from rotating in the direction opposite to the direction of the arrow W, and the tooth surface in contact with the pin 24 becomes almost flush with the back surface 51 of the presser plate 5 as shown in FIG. can move smoothly in the backward direction, in the direction of arrow X', while contacting the back surface 51 of the holding plate 5.

FIG. 6 is an enlarged side view showing still another embodiment of the picker moving section, in which only the pin 24 of the picker is shown, and the pins 24 are shown to move in the order of FIGS. 6a to 6c, and FIG. - The same reference numerals as in FIG. 5 indicate the same parts or parts having the same function.

In this embodiment, the picker moving part 8 provided at the terminal end of the presser plate 5 includes a lever 81 rotatably supported by a shaft 82, a spring 83 for drawing the lever 81 to the end surface of the presser plate 5, The lever 81 has a stopper 84 that prevents excessive displacement of the lever 81, and is brought into close contact with the end surface of the presser plate 5 by a spring 83. A stepped portion 81a is provided.

As shown in FIG. 6a, the pin 24, which has advanced in the forward direction of arrow X without interfering with the surface 53 of the presser plate 5, is supported by the shaft 82 and brought into close contact with the end surface of the presser plate 5 by the spring 83. After contacting the surface of the lever 81 that is
The lever 81 is rotated about the shaft 82 so as to move away from the end surface of the holding plate 5 against the force in the X' direction.

As the lever 81 continues to rotate and comes into contact with the stopper 84 as shown in FIG. The pin 24 is also moved in the direction of arrow Z against this. When the movement in the direction of arrow Z progresses and reaches the stepped portion 81a, the lever 81 is pulled by the spring 83 so that the pin 24 enters the stepped portion 81a. When the pin 24 finishes its forward movement and starts moving in the backward direction, when the lever 81 comes into close contact with the end surface of the presser plate 5 as shown in FIG. Since it is substantially flush with the back surface 51 of the presser plate 5, the pin 24 can move smoothly in the backward direction, ie, the arrow X' direction, while contacting the rear surface 51 of the presser plate 5.

The picker moving unit has been described above with reference to various embodiments, but the speed at which the claw portion 21 of the picker 2 leaves the plate-like object such as a card can be selected by appropriately designing each configuration. can do.

In addition, in these embodiments, the picker 2 is provided with a pin 24, but by using a ball bearing with less friction in place of the pin 24, smoother operation can be expected. This includes design matters.

Further, in the above description, the transmission device from the drive source 23 to the picker 2 is not specified, but known mechanical elements such as a combination of a cam and a lever or a combination of a crank and a link may be used.
As the drive source 23, in addition to an electric motor, various types of power such as a solenoid, pneumatic pressure, and hydraulic power can be used.

As explained in detail above, according to the device according to the present invention, there is no needless contact process between the object to be sent, which is a plate-shaped object such as a card, and the picker, so there is no need to worry about damaging the object. , the movement of the object to be delivered within the hopper becomes simple, and the synergistic effect of these advantages increases the durability of the delivery device itself and improves the delivery function.
Furthermore, it is possible to provide a rational device for dispensing plate-shaped objects such as cards, which utilizes the operation of the picker, which is essential in a device that dispenses cards one by one by the reciprocating motion of the picker.
