Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for dispensing articles, etc., and for ejecting coins in a coin dispensing machine, money changer, etc., or articles in a vending machine, etc., sequentially from a storage section in which they are arranged and stored. Concerning a device for dispensing.

Conventional dispensing devices of this type have a structure in which the extrusion member that pushes out the objects to be thrown, such as coins and articles, moves back and forth on the same line. When the extrusion member completes its backward movement, it is moved to the position where the next object to be thrown is to be extruded. For this reason, the next object cannot be pushed out until the next object is moved to the extrusion position, and the next pushing operation must be carried out with sufficient time, making it necessary to continuously push out the next object. When discharging objects at different times, the interval between dispensing becomes longer, and even when discharging a single object, the extrusion member must be accurately stopped at a predetermined position. If the stop position is uncertain and the extrusion member moves too much, there is a risk that the next object will be erroneously ejected, and there is a limit to the ejecting speed.

For this reason, as shown in Japanese Patent Publication No. 55-3256, after the extrusion member has pushed out the object, it retreats from the extrusion line of the object and returns to the line where it retreated from the object to be extruded next. A dispensing device configured to do this has been developed. However, in this configuration, the pushing member is moved to the pushing position of the object by a cam operated by an electric motor and a group of levers operated by this cam, and the pushing member is advanced from that position to release the object. After extruding the object and pushing out the object, the extrusion member is moved back from the position of the object. It has the disadvantage that timing adjustment such as advance/retreat timing is complicated and the structure is complicated.

Furthermore, as described in Japanese Utility Model Publication No. 51-31038, there is a known configuration in which the pushing member moves below the object to be thrown next and returns when making a backward movement. In this configuration, when the swinging member that swings back and forth moves forward, the swinging member pushes the extrusion member that is pivoted to the sliding member, and the extrusion member maintains an upward angle and throws out the object. When the moving member moves back, the pushing member is released from the pressure of the swinging member and rotates downward by its own weight to be positioned below the next object to be thrown, and the tension spring causes the sliding member to return to its original position. It has a similar structure. In this structure, the extrusion member is configured to rotate downward by its own weight, so the extrusion member will surely rotate downward depending on the magnitude relationship between the extrusion member's own weight and the pressing force of the swinging member. However, if the extrusion member does not move downward from the standby position for the next object to be thrown, the next object will not be thrown until the extrusion member returns and the next object is moved to the extrusion position as described above. There is a limit to the continuous dispensing speed, and if the dispensing member rubs against the bottom of the article before returning, there is a risk of damaging the article. Since the return movement of the member is performed by a swinging member, and the return is performed by a sliding member that returns to its original position by a tension spring, there are problems in that the number of parts is large and the structure is complicated.

The present invention was made in view of the above-mentioned drawbacks, and includes a friction body that moves an extrusion member rotatably supported by a swing member integrally with the swing member, and pushes out the push-out member against the frictional force of the friction body. The member is rotated to form a substantially rectangular cycle in the locus of the dispensing operation of the extrusion member,
To provide an article dispensing device which can improve the dispensing speed with a simple structure and can reliably dispose of the articles to be disposed of.

Next, the configuration of an embodiment of the present invention will be explained with reference to the drawings.

1 is an object to be thrown such as an article, for example, a coin storage section;
It is formed by a receiving tube 3 arranged on a base plate 2, and a discharge part 5 through which a piece of hard material 4 can pass is cut out at the front of the lower end of the receiving tube 3, and at the rear of the lower end of the receiving tube 3. An extrusion opening 6 is formed at a height lower than the thickness of the coin. And this receiver 3 is the base plate 2
Several are arranged side by side on the top.

Next, reference numeral 7 denotes a swinging member in the form of an elongated plate, which is provided corresponding to each of the receiver tubes 3, and whose intermediate portion is rotatably supported by a support shaft 8. Each of the swinging members 7 has a long groove 9 formed in its upper end in the longitudinal direction of the swinging member 7, and each of the long grooves 9 has a cam plate 1.
A pin 11 protruding from 0 is engaged. The cam plates 10 are each attached to a rotating shaft 13 supported by a mounting plate 12, and attached to a worm wheel 14 provided on the rotating shaft 13 and a drive shaft 17 of an electric motor 16 supported by a support plate 15. Worm gear 18 is engaged. The support plate 15 that supported the electric motor 16 and the mounting plate 12 that supported the rotating shaft 13 of the cam plate 10 are fixed to a support plate 19, and each support plate 19 extends from the rear edge of the base plate 2 to each receiving plate. A back plate portion 20 bent vertically along the tube 3
are fixed to the respective receiving tubes 3 in correspondence with each other.

Further, the cam plate 10 is formed into a substantially fan shape, and a switch 23 provided with an actuator 22 that is operated in contact with a cam edge 21 of the cam plate 10 is connected to the support plate 1.
It is attached to 9. This switch 23 is adapted to stop the electric motor 16, which has been started by the coin ejection signal, when the actuator 22 is actuated by the cam plate 10.

Next, reference numeral 24 denotes an elongated plate-shaped extrusion member, which is rotatably mounted on a shaft 26 fixed to the lower end of the swinging member 7.
A sliding washer 27 fitted to the shaft 26 is interposed between the push-out member 24 and a friction body such as a leaf spring 28 fitted to the shaft 26, and the leaf spring 28 is fitted to the shaft 26. Combined sliding washers 29 and washers 3
By tightening the nut 32 screwed onto the threaded portion 31 of the shaft 26 with the
The extrusion member 24 is held at an angle with the swinging member 7 by frictional force with the swinging member 7. This extrusion member 24 is located below the substrate 2,

are integrally formed in a protruding manner. Furthermore, a roller 36 is attached to the pin 35 fixed to the tip of this extrusion member 24.
is rotatably supported.

A roller 36 pivotally supported at the tip of the extrusion member 24
is rolled between a first regulating surface 37 formed on the lower surface of the substrate 2 and a second regulating surface 39 formed on the upper surface of the guide plate 38 provided below the substrate 2. It's summery. When this roller 36 rolls forward along the first regulating surface 37 , the extrusion portion 34 of the extrusion member 24 moves toward the guide groove 33 of the substrate 2 .
It is now projected more upwards. The protrusion height of the extrusion portion 34 is slightly lower than the thickness of the lowest coin stored in the receiving tube 3 and supported on the base plate 2.
The coin is pushed out through the lower end of the coin.

The guide plate 38 is arranged so that the upper end of the extrusion part 34 of the extrusion member 24 is positioned below the upper surface of the substrate 2 when the roller 36 rolls backward along the second regulating surface 39. 2, and is fixed below the substrate 2 while maintaining a distance between the substrate 2 and the substrate 2.

Next, the operation of this embodiment will be explained.

When the electric motor 16 is started by a coin dispensing command signal, the drive shaft 17 rotates, the cam plate 10 is rotated, and the pin 11 of the cam plate 10 moves counterclockwise from the starting position shown in FIG. The swinging member 7, which engages the pin 11 with the long groove 9, is rotated forward in the counterclockwise direction in FIG.
presses the extrusion member 24 against the swinging member 7, so a frictional force acts between the extrusion member 24 and the swinging member 7, and the extrusion member 24 as well as the swinging member 7 also has its distal end facing upward. The extrusion portion 34 of the extrusion member 24 is moved from the solid line position in FIG. 1 to the chain line position 34 _a
When the roller 36 contacts the first regulating surface 37, the pin 11 of the cam plate 10 further rotates the swinging member 7, and the push-out member 24 attached to the lower end of the swinging member 7 moves forward. At this time, the roller 36 supported by the extrusion member 24 is restricted from moving upward by the first regulating surface 37, so the extrusion member 24 resists the extrusion force of the leaf spring 28 and supports the shaft 26. The roller 3 is rotated clockwise in FIG.
6 rolls on the first regulating surface 37, the extrusion member 24 moves linearly toward the front, and the extrusion part 34 of the extrusion member 24 is guided by the guide groove 33 of the base plate 2 to extrude the receiving cylinder 3. Enter the receiving tube 3 through the opening 6 and insert the receiving tube 3.
The coin 4 in the lowest row is pushed, and the coin 4 is ejected forward from the ejection part 5 of the receiving tube 3. The extrusion part 34 of the extrusion member 24 is located at the position 3 of the ejection part 5 of the receiving tube 3.
_4b , the pin 11 of the cam plate 10 reaches a position where the direction of rotation of the swinging member 7 is reversed, and the swinging member 7 moves clockwise in FIG.
The extrusion member 24, which is rotated backwards around the center and moved by the pressing force of the swinging member 7 and the leaf spring 28, is also moved with the tip side facing downward.
is in contact with the second regulating surface 39, and the upper end of the extrusion part 34 of the extrusion member 24 is located at a position 3 below the upper surface of the substrate 2.
_4c , the roller 36 rolls on the second regulating surface 39 due to the rotation of the swinging member 7, and the pushing member 24 moves around the shaft 26 against the pressing force of the leaf spring 28 as shown in FIG. It is moved backward while rotating in the direction.

The cam plate 10 is driven by the electric motor 16 and rotates counterclockwise from the solid line position in FIG. 1, and the cam edge 21 pushes the actuator 22 of the switch 23 to close the holding circuit of the electric motor 16. Electric motor 16
continues to be driven, but while the pushing member 24 is moving backward, the cam edge 21 of the cam plate 10 releases the pressure from the actuator 22 of the switch 23, the power to the electric motor 16 is cut off, and the cam plate 10 rotates due to inertia. The operation continues until the cam plate 10 reaches the starting position before pressing the actuator 22 of the switch 23 again and stops, and the swinging member 7 and the ejecting member 24 are returned to the positions shown in FIG.

In this way _{, the extrusion portion 34 of the extrusion member 24 is located at a position indicated by the reference numeral 34 a from the solid} line position in _FIG . The coins are dispensed in a cycle in which the trajectory from position 34 _c to the position shown by the solid line is approximately rectangular.

The extrusion portion 34 of the extrusion member 24 is indicated by reference numeral 34a _.
When moving from the position shown by the symbol 34 _b to the position shown by the symbol 34 _b , and when moving from the symbol 34 c to the solid line position, the swinging member 7 and the sliding washer 27 are kept fixed and are not pushed out against the sliding washer 27. The member 24 slides against the frictional force, and the pusher member 24 and the leaf spring 28
is maintained in a fixed state, and sliding occurs between the shaft 26, nut 32, and washer 30 fixed to the swinging member 7, and the sliding washer 29 and leaf spring 28, which are in the fixed state.
From the position where the extrusion part 34 is indicated by the solid line in FIG.
When moving from the position indicated by _a and the position indicated by the symbol 34 _b to the position indicated by the symbol 34 _c , the extrusion member 2
4 moves integrally with the swinging member 7 and sequentially repeats the operation of drawing the rectangular locus, dispensing a coin every cycle of this operation.

Note that in this embodiment, the swinging member 7 and the pushing member 24
Since the position of the shaft 26 to which the coins are pivoted is located below the position of the bottom surface of the lowest coin stored in the receiving tube 3, the extrusion part 34 is reliably prevented from being pressed down by the coin during hardening. Coins can be pushed out.

Further, in the embodiment, the extrusion portion 34 of the extrusion member 24
Although the structure in which the next coin is quickly placed on the substrate 2 at the extrusion position because the width in the coin extrusion direction is narrowed in the shape of a protrusion has been described, the extrusion part 34 is not necessarily the same as in the above embodiment. It is not limited to structure.

Further, in the above embodiment, the leaf spring 28 is used as the friction body.

Further, as shown in FIGS. 7 and 8, a sliding clutch 50 in the radial direction is attached to the swinging member 7 as a friction body.
The shaft 51 may be fixed to the extrusion member 24, and the degree of friction between the clutch 50 and the shaft 51 may be adjusted using an adjusting screw 53 screwed into the tightening arms 52, 52 of the clutch 50.

The present invention is not limited to the structure in which the frictional force is directly applied to the extrusion member 24 and the swinging member 7 as described above.

Furthermore, in the embodiment described above, the storage unit 1 has a structure in which coins are stacked vertically in the receiver 3 and stored, and the coins at the bottom are released first.
