Abstract

PURPOSE:To prevent a coin carrying lifter from getting blocked with coins by making an oscillating wall formed at part of the coin guide wall of a coin path for guiding coins downward from a top opening oscillate around the lower edge side of the oscillating wall. CONSTITUTION:When delivery of coins is started from a coin delivering section 4a, a motor 39 is actuated to move a carrying belt on a coin lifting up section side. At the same time, the large- and small-diameter rolls 37 and 38 of a coin chuter 3 start to rotate. These rolls rotate in the same direction shown by the arrows and a coin guide wall 34 is started to make oscillation around its lower edge through a coupling board by the eccentric movement of an eccentric cam. When the coins CN drop, the coins CN are carried in the lateral direction towards a coin exit 35a by means of the rolls 37 and 38 under the guidance of a pair of guide walls 33 and 34.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a coin transport lifter that lifts coins dispensed from a coin sorting device to a coin return slot located above. This invention relates to a coin transport lifter equipped with a coin shooter capable of transporting coins one by one toward the main body of the coin transport lifter without causing jams.

[Prior Art] Vending machines and the like are equipped with a coin sorting device that can sort and store inserted coins by denomination in order to determine whether the inserted coins are genuine or fake and to dispense change. In this coin sorting device, a coin passage inside the device is configured so that the inserted coins are moved by their own weight. Therefore, the coin input port is necessarily located at the highest position of the device, and the coin return port is located at the lowest position.

In a vending machine or the like incorporating this coin sorting device, there is a difference in height between the coin input slot and the coin return slot, and both cannot be set at the same height, which is convenient for the product purchaser. Therefore, the applicant has decided to
As shown in the figure, the coin dispensing section 1 of the coin sorting device 11
The coins CN paid out from 1a are transferred to the vertical conveyor bell) 13a.
This paper proposes a configuration in which the coin return opening 14 is set at the same height position as the coin input opening 15 by forcibly lifting it upward using a coin transport lifter 13 having a -20994).

Such a coin lifter 13 is a coin sorting device! Coin chute 16 arranged below the coin dispensing part 11a of 11
and a coin lift-up section 17 for lifting and amplifying the coins guided and fed into the chute 16. As shown in an enlarged view in FIG. 9, the coin chute 16 has a shape whose lower end is narrowed to a width that allows only a portion of the coins to pass through, and the coins received from the opening at the upper end are lifted one by one into the coin chute 16. The coins are fed into the lower end coin inlet of the up section 17.

[Problem to be solved by the invention]

Here, if the height difference between the coin dispensing part 11a of the coin sorting device and the lower end coin inlet of the coin lift amplifier part 17 can be made large, the coin chute 16 can be made longer, so the shape of the coin chute can be increased. The coin lift-up section 1 gradually narrows downward and securely lifts the coins one by one.
It can be sent to the 7 side. However, if this drop cannot be made large, it is often not possible to set the shape of the coin chute appropriately, and the coins may become jammed in the chute because there is no momentum for the coins to fall through the chute due to their own weight. There is a high probability of

For example, as shown in FIG. 10, in the coin chute 18 where the drop from the upper end opening 18a to the coin outlet 18b at the lower end is small, the coins CNI and CN2 dispensed at the same time are The coin may get stuck inside the chute.

Alternatively, as shown in FIG. 12, the coin CN may straddle between the guide walls 18c and 18a on both sides, causing problems such as being stuck there.

The present invention focuses on these problems and aims to realize a coin transport lifter equipped with a coin shooter that can reliably feed coins one by one toward the coin lift-up section.

[Means to solve the problem]

In order to solve the above problems, in the coin shooter of the coin transport lifter according to the first invention of the present application, a coin guide is provided which defines a coin passage for guiding coins downward from the upper end opening. A small portion of the wall is a rocking wall that can swing, and this rocking wall is rocked by a rocking means.

Further, the coin shooter of the coin transport lifter according to the second invention of the present application has a pair of coin guide passages that are inclined downwardly from the upper end opening toward each other, and these coin guide walls It is characterized in that a pair of coin conveying rollers rotating in the same direction are disposed in parallel and facing each other at a lower position. It is preferable that a spiral protrusion be formed on the outer circumferential surface of at least one side of the coin transport roller in a direction opposite to the roller rotation direction toward the coin transport direction. Furthermore, it is preferable that the pinch of this spiral projection be larger than the outer diameter of the coin to be conveyed.

On the other hand, the coin shooter of the coin transport lifter according to the third invention of the present application includes a swinging means for swinging at least one of the pair of coin guide walls described above, and a pair of coin transport rollers. It is characterized by

[Effect]

In the first invention of the present application, even if a coin is straddled between the coin guide walls, the swing portion formed on the coin guide wall is pivoted by the swing means. Therefore, the coin will not remain stuck there, but will fall downward.

Furthermore, in the second invention of the present application, the coins that have fallen along the pair of coin guide walls arrive between the pair of coin transport rollers. These rollers are rotating in the same direction. Therefore, if multiple coins fall here at the same time, the coins that are in contact with the rollers on one side will be sent back out from between the rollers, and the coins that are in contact with the rollers on the other side will be sent back to the outside. is fed between the rollers. Therefore, each coin is sandwiched between the pair of rollers and conveyed toward the coin lifter main body. If a spiral protrusion is formed on the outer periphery of the conveyance roller, the coins are efficiently conveyed toward the coin lifter main body by this protrusion.

〔Example〕

The present invention will be described in detail below with reference to the drawings.

FIG. 1 shows the overall structure of the coin conveying lifter of this example. As shown in the figure, the coin conveying lifter 1 of this example is
It consists of a vertically long coin lift-up part 2 and a coin shooter 3 attached to the lower side surface of the coin lift-up part 2. Above the coin shooter 3, as shown in phantom lines in the figure, a coin dispensing section 4a such as a coin sorting device 4 is located. The coin lift-up section 2, like the coin lift-up section shown in FIG.
A coin conveying belt having a coin conveying protrusion on its surface is placed between these racks. The upper end side of the case 21 is curved and protrudes toward the front side of the case, and a coin return opening 25 is opened in this part.

The overall structure of the coin shooter 3 will be explained with reference to FIGS. 1 and 2. This coin shooter 3 has a horizontally long rectangular parallelepiped shape as a whole, and the case 31 is formed with attachment parts 311 and 312, through which the shooter is attached to the side surface of the case 21 of the coin lift-up part. It is being

The coin shooter 3 has a coin receiving opening 32a formed at its upper end, and a coin guide passage 32 which is tapered downward into a funnel shape. This coin guide passage 32 is
It is divided into a pair of coin guide walls 33, 34 extending in the long side direction and a pair of coin guide walls 35, 36 extending in the short side direction.

As shown in FIG. 2, the pair of rigid interior walls 33 and 34 extending in the longitudinal direction have curved cross-sections that protrude toward each other as they move downward. On the other hand, of the pair of guide walls extending in the short side direction, the guide wall 35 on the side of the coin lift-up section 2 has a coin outlet opening 3 at its lower end.
5a is formed, the other guide wall 36 being inclined towards the side of this outlet opening.

A large diameter roller 37 is rotatably attached to the case 31 below the coin guide wall 33 extending in the longitudinal direction. The large diameter rollers 37 are arranged horizontally so that their outer peripheral surfaces 371 are continuous with the surface of the guide wall 33. Similarly,
A small-diameter roller 38 is rotatably attached to the case 31 below the other coin guide wall 34, and is horizontally arranged with its outer peripheral surface 381 continuing to the guide wall surface shape.

Both of these rollers 37, 38 are disposed facing each other so that their rotational axes are at approximately the same height, and the distance between them is set to be slightly larger than the thickness of one part of the coin.

FIG. 3 shows the driving force transmission mechanism of the roller 37.3 with the side portion of the case 31 removed.

A motor housing section 313 is formed in the case 31, and the drive motor 39 is housed here.

The output shaft 391 of this drive motor 39 is connected to the gear type reduction mechanism 4
A rotary shaft 4 rotatably supported by the case 31 via the rotary shaft 1
It is connected to 2. A drive pulley 43 is fixed to one end of this rotating shaft 42 .

A driven pulley 4 is attached to the end of the rotating shaft 372 of the large diameter roller 37.
4 is fixed, and a belt 45 is stretched between these boots IJ43 and 44. In addition, the driven pulley 4
A driving pulley 46 is coaxially fixed to 4.
This pulley 46 is connected via a belt 48 to a driven pulley 47 fixed to the end of the rotating shaft 382 of the small diameter roll 38. Note that the drive motor 39 described above functions as a drive source for the coin conveying belt of the coin lift-up section 2.

In the figure, the power transmission mechanism from the motor 39 to this coin conveying belt is omitted.

Here, the large diameter roll 37 and the small diameter roll 38 are rotationally driven in the same direction by the above-mentioned power transmission mechanism. In this example, when the motor is driven, it rotates in the direction shown by the arrows in FIGS. 2 and 3. And these rolls 37.
Spiral protrusions 373 and 383 are formed on the outer circumferential surfaces 371 and 381 of 38, respectively. These spiral protrusions draw a spiral in the coin conveyance direction in the opposite direction to the rotation direction of the roll. Moreover, the pitch of these spiral protrusions is set larger than the maximum diameter of the coin to be conveyed.

On the other hand, the coin guide wall 34 extending in the long side direction is removable from the case 31, and is a swing type guide that swings toward and away from the other guide wall 33 around its lower end. It is a wall. This attachment/detachment mechanism and swing mechanism will be explained with reference to FIGS. 4 and 5. Arc-shaped mounting legs 341 and 342 are formed at the lower ends of both end faces of the guide wall 34 and are removably attached to the outer periphery of the rotating shaft 382 at both ends of the small diameter roller 38 . A rotating wheel 382 of a small diameter roller to which these legs are attached serves as the center of swing of the guide wall 33.

A tip of a horizontal engagement shaft 344 biased by a coil spring 343 protrudes from the middle of one end surface of the guide wall 34 . The protruding end of this retaining shaft 344 is connected to the case 31.
The retaining hole 5 formed at the tip of the connecting plate 51 supported on the side of
It is inserted into 11. A lever 344a is integrally formed on the base end side of this horizontal engagement shaft 344, and this lever 344a is connected to a cover 344 that forms the back surface of the guide wall 34.
It protrudes to the outside from an opening 345a.

When this lever 344a is moved against the spring force, the horizontal engagement shaft 344 is disengaged from the connecting plate 51 side, so that the guide plate 34 can be removed from the case 31 side.

Next, the connecting plate 51 is movable within a sliding groove 52 integrally formed in the case 31 in a direction perpendicular to the guide wall 34 .

Here, a rotating shaft 42 to which a driving pulley 43 is attached
An eccentric cam 53 is fixed to the cam 53, and rotates eccentrically when the rotating shaft rotates.

The end of the connecting plate 51 is connected to the eccentric cam 53, and the eccentric rotation of the eccentric cam causes the connecting plate 51 to linearly move back and forth in its axial direction. This reciprocating linear movement causes the guide wall 34 to swing around its lower end.

Next, the operation of the coin conveying lifter 1 of this example will be explained, focusing on the coin conveying operation in the coin shooter 3. Each driving portion of the coin transport lifter is driven in conjunction with the coin dispensing operation of the coin sorting device. Such a drive control system can employ a known configuration. Coin dispensing section 4 of coin sorting device
When coin dispensing starts from a, the motor 39 is driven to start moving the conveyor belt on the coin lift-up section side. At the same time, as shown in FIG. 6, on the side of the coin shooter 3, large diameter and small diameter rolls 37.3
8's rotation begins. These rolls rotate in the same direction as indicated by the arrows in the figure. Further, due to the eccentric rotation of the eccentric cam 53, the coin guide wall 34 starts to swing around its lower end via the connecting plate 51. When the coin CN dispensed toward the coin shooter 3 in such a driven state falls, the coin CN is guided by the pair of guide walls 33.34 and rolled onto the roll 37.3.
Arrive during the day. Both rollers have spiral projections 373.
383 are formed, and when the roller rotates, these protrusions move so as to feed the coin toward the coin outlet 35a. Therefore, the coin CN is transported laterally toward the coin outlet 35a by these rollers. In this example, a spiral protrusion 373.3 formed on each roller
Since the pitch of 83 is set larger than the outer diameter of the coin to be conveyed, the coin to be conveyed is reliably conveyed while being placed between adjacent protrusions.

The coins pass through the coin outlet 35a and reach the lower end side of the coin lift-up section 2. Thereafter, the coin is lifted up to the coin return opening 25 above by the conveyance belt while being engaged with the protrusion of the conveyance belt of the coin lift-up section, and is returned from this return opening.

Here, as shown by the imaginary line in FIG. 5, a case will be described in which the coin CN that has fallen from the coin dispensing section is in a state where it straddles between the pair of guide walls 33 and 340. in this case,
Since one of the guide walls 34 swings back and forth as described above, the coin CN does not stay in a state where it straddles both walls like this, but is reliably positioned below. Dropped between rolls 37.38.

On the other hand, a case will be described in which a plurality of coins are paid out at the same time and fall during a period of 37.3 days between a pair of rolls.

Figure 7 shows two coins CNI.

This shows the state in which CN2 has fallen between the rolls.

In this case, since both rolls are rotating in the same direction, the roll 33 in contact with the coin CNI is
An attempt is made to separate the NI from the coin CN2 and pull it up from between the rolls to remove it. On the other hand, the roll 34 with which the coin CN2 is in contact acts to draw the coin CN2 between the rolls. Due to the operation of both rolls, only one coin CN2 is drawn between the rolls and conveyed toward the coin outlet 35a. In this way, in this example, it is possible to avoid a plurality of coins from being jammed between the pair of rolls, and it is possible to always transport coins one by one toward the coin lift-up section.

In addition, in the above embodiment, the opposing coin guide wall 3
In 3.34, only the guide wall 34 side is of the swing type, but the other guide wall may be of the swing type, or both may be of the swing type. Furthermore, it goes without saying that a swinging mechanism having a structure different from that in the above example may also be used.

On the other hand, in the above example, a spiral protrusion for coin conveyance is formed on the outer periphery of the pair of coin conveyance rollers, but it is of course possible to form such a protrusion only on one side. Furthermore, the spiral protrusions do not need to be continuous protrusions as in the above example, and of course may have a structure in which hemispherical protrusions are arranged in a spiral manner, for example.

[Effects of the Invention] As explained above, in the coin conveying lifter of the present invention, the swinging coin guide wall portion is disposed in the coin shooter that guides the dispensed coins toward the coin lift-up section. It is. Therefore, it is possible to avoid the coins that have been dispensed and fallen into the coin shooter from becoming stuck there between the coin guide walls.

Further, in the present invention, a pair of coin transport rollers rotating in the same direction are arranged below the coin guide wall of the coin shooter. Therefore, when a plurality of coins are dispensed at the same time and fall into the coin shooter, the coins are taken one by one between these rollers by the interaction of the pair of coin conveying rollers. Therefore, the coins can be fed one by one toward the coin lift-up section without causing a coin jam.

When a spiral protrusion capable of transporting coins in the coin transport direction is formed on the outer circumferential surface of the pair of coin transport rolls, the coins will not remain between the coin transport rolls due to slippage, etc. This spiral projection provides an advantage in that coins are reliably conveyed. In particular, when the pinch of the spiral protrusions is made larger than the outer diameter of the coin, the coin is conveyed between the protrusions, which provides the advantage that the coin is conveyed efficiently by the rolls. .
