The pachinko doffing apparatus 1 has two left and right unit side plates 2, 2 between which a main shaft 3 is rotatably supported in a two-sided state.
On the main shaft 3, four main wheels 4 made of, for example, robust stainless steel are arranged and fixed side by side.
A gear 5 is fitted to an end of the main shaft 3 protruding outside the side plate 2, and the gear 5 is meshed with a pinion gear 7 of a drive motor 6 via a gear 8.

Further, at the center of the outer periphery of each main wheel 4,
A ring-shaped anti-rotation member 9 made of rubber having a large coefficient of friction, for example, silicone rubber, is fitted, and a spherical concave portion 10 whose surface is exposed at the bottom is arranged in the circumferential direction. The pachinko balls 99 taken into the recess 10 can be rotated and conveyed without rotating in the recess 10. This pachinko ball fryer 1
Is configured to lift pachinko balls 99 in four rows, and the recesses 10 of the adjacent main wheels 4
The phase is shifted by a pitch.

As a result, the four rows of recesses 10 take in the pachinko balls 99 with a shift of 1/4 pitch, so that the four rows of pachinko balls 99 are not locked simultaneously. The noise level when the pachinko balls 99 are lifted is determined by the pachinko balls 99
The noise level can be minimized by shifting the biting timing of the four rows of pachinko balls 99 because the highest level is obtained when the pachinko balls 99 are bitten.

Further, wheel housings 11, 12 and a pachinko ball guide 13 are arranged along the main wheel 4 around the main wheel 4, and are introduced into the wheel housing 11 from the upper left side in FIG. Pachinko balls 99
Is rotated by the main wheel 4 rotating in the direction of the arrow while being guided by the wheel housing 12, and the pachinko balls 99 are detached from the wheel housing 12 at the right side position in FIG. 1 to reach the ball hopper 103. It is fed into the ball guide 13 and lifted upward.

A solid lubricant 12 made of fluororesin or the like is provided on the side of the wheel housing 12 facing the main wheel 4.
A and a cushion 12B made of rubber or the like are provided, and when the pachinko ball 99 is held in the concave portion 10 of the main wheel 4 and rotated and conveyed, the solid lubricant 12A is slightly scraped off and the pachinko ball 99 is cut. Because it adheres to the surface of
The transport resistance of the pachinko balls 99 in the lifting pipe 14 and the like is reduced.

On the lower side of the main wheel 4 near the pachinko ball 99 introduction position, as shown in FIG. 5, an inner peripheral portion 15 made of synthetic rubber having a hardness of 90, for example, so as not to be easily deformed. In addition, a sub wheel 19 for attraction, which is formed integrally with an outer peripheral portion 17 made of synthetic rubber having a hardness of 50 so as to be easily deformed, is provided. A shaft hole 16 is formed at the center of the inner peripheral portion 15 of the auxiliary wheel 19, and arcuate concave portions 18 are arranged in a gear shape in the circumferential direction of the outer surface of the outer peripheral portion 17.

The four auxiliary wheels 19 are arranged as shown in FIG. 3 so that the pachinko balls 99 can be rotated in four rows facing the respective recesses 10 of the main wheels 4 arranged in four rows. It is attached to the rotating shaft 20 as shown. That is, the pachinko balls 9 rotated and fed in four rows
9 are fixed to the rotating shaft 20 at a predetermined interval with a phase shifted by 1/4 pitch from each other, and the rotating shaft 20 is horizontally mounted on the unit side plates 2 and 2 so as to be freely rotatable.

Numeral 21 is a streak locking means repeatedly formed at the same pitch over the entire circumference of the central portion of the rotary shaft 20 to fix the auxiliary wheel 19 to the rotary shaft 20. It is a streak-like locking means that is formed in the circumferential direction of the shaft hole 16 so as to be fittable. Reference numeral 23 denotes a mountain portion interposed between the concave portions 18 adjacent to each other in the outer circumferential direction of the outer peripheral portion 17.

Next, the pachinko ball introducing section 24 for supplying the pachinko balls 99 to the auxiliary wheel 19 will be described. As shown in FIG. 2, the pachinko ball introducing portion 24 includes five partition plates 25 disposed at equal intervals between the unit side walls 2 and 2 of the pachinko ball lifting device 1, and a pair of partition plates 25. There are four pachinko ball passages formed by four pachinko ball rails 26 disposed therebetween. The pachinko ball rail 26 is provided at an inclination of, for example, 5 degrees so that the pachinko ball 99 is transferred from the ball storage unit 101 to the auxiliary wheel 19 by its own weight.

On the back side, as shown in FIG. 1, a shaft 27 is supported by the unit side walls 2 and 2 in a double-supported state, and a substantially quadrangular columnar cam 28 is fixed to the shaft 27. ing. One end of the shaft 27 protrudes outside the unit side wall 2, and the tip of the shaft 27 is provided with the gear 8 as shown in FIG.
Is attached. The gear 8 meshes with the pinion gear 7 of the drive motor 6 and also meshes with the gear 5 fitted on the main shaft 3 to which the main wheel 4 is attached, so that the rotation of the drive motor 6 is transmitted to the main wheel 4. It also works to communicate. Further, in each of the pachinko ball passages, a swinging piece 29 is arranged rotatably by a shaft 30, and these swinging pieces 29 come into contact with the cam 28 so as to interlock with the movement of the cam 28. Is provided.

Accordingly, when the drive motor 6 rotates, the cam 28 is rotated by the pinion gear 7 and the gear 8, and in synchronization with this, the swinging piece 29 swings about the shaft 30, and a two- or three-stage stacking is performed. One pachinko ball 99 entering in the state of
Align the columns. Since the pachinko ball introduction portion 24 is configured as described above, the height H shown in FIG. 1 can be reduced, and accordingly, the capacity of the ball storage portion 101 can be increased accordingly.

The pachinko ball guide 13 has a guide claw 13a at a position facing the main wheel 4, and a stopper 32 urged toward the inside of the pachinko ball guide 13 by a leaf spring 31 at the center. Are arranged. The stopper 32 is for preventing the main wheel 4 from rotating in the reverse direction due to the weight of the pachinko balls 99 remaining in the lifting pipe 14 when the drive motor 6 stops.
As a result, the pachinko balls taken into the recess 10 of the main wheel 4 and conveyed by rotation are guided into the pachinko ball guide 13 by the guide pawls 13a, and are prevented from being fed backward by the stoppers 32. Ascending from the side so as to be pushed.

Optical switches (not shown) are attached to portions of the unit side plates 2 and 2 corresponding to the pachinko ball introducing portion 24, and the presence or absence of the pachinko balls 99 in the pachinko ball introducing portion 24 is detected, and the pachinko ball is detected. When 99 is no longer sent, a signal to stop the apparatus is sent.

The operation and effect of the sub wheel 19 in the pachinko doffing apparatus 1 will be described with reference to FIG. Since the auxiliary wheel 19 is attached to the rotatable rotation shaft 20, even when the auxiliary wheel 19 is not rotating, the pachinko ball 99 that has rolled on the inclined pachinko ball rail 26 is received in the concave portion 18. With the momentum of the pachinko balls 99 having rolled, the drive motor 6 rotates toward the main wheel 4 that is rotationally driven, and the pachinko balls 9 rotate.
9 is transferred to the recess 10 of the main wheel 4.

When the pachinko balls 99 are exchanged, the concave portion 18 of the auxiliary wheel 19 and the concave portion 10 of the main wheel 4 do not face each other, and for example, enter the concave portion 18 of the auxiliary wheel 19 as shown in FIG. When the crest 33 of the main wheel 4 comes into contact with the pachinko ball 99 which has been rotationally fed by the rotation of the main wheel 4 and the sub-wheel 19 receives a force from the main wheel 4, the rotation shaft 20 of the sub-wheel 19 is rotatable on the side walls 2, 2. 6B, the rotating shaft 20 rapidly rotates in the direction in which the force received from the main wheel 4 decreases, that is, the side where the concave portion 18 of the auxiliary wheel 19 and the concave portion 10 of the main wheel 4 face each other. The recess 18 holding the pachinko ball 99 of the sub wheel 19 faces the recess 10 of the wheel 4, and the pachinko ball 99 is smoothly transferred from the recess 18 to the recess 10 of the main wheel 4.

Then, the pachinko ball 99 is moved to the auxiliary wheel 19.
Once it is delivered from the recess 18 of the main wheel 4 to the recess 10 of the main wheel 4, the main wheel 4 and the sub wheel 19 are interlocked via the delivered pachinko ball 99, and the pachinko balls 99 And recess 1 of main wheel 4
It is held at 0 and rotated and fed into the lifting pipe 14.

In addition, the auxiliary wheel 19 is a pachinko ball 99
The main wheel 4 and the auxiliary wheel 19 are mechanically linked by gears or the like, because the main wheel 4 and the rotation of the main wheel 4 are interlocked with each other via a gear. In this case, significant wear of the ridge 23 made of the soft member of the auxiliary wheel 19 is avoided.

When the main wheel 4 and the sub wheel 19 are rotating in conjunction with each other, the timing at which the pachinko balls 99 flow varies, and for example, as shown in FIG. The pachinko ball 99 may be interposed between the peak 23 and the outer wall 34, but the peak 23 formed of a soft member is bent as shown in FIG. Eventually, the pachinko ball 99 enters the concave portion 18 before or after the peak portion 23 as shown in FIG. 7C, and the locked state is avoided. In this way, the pachinko balls 99 are fitted into the recesses 18 of the sub wheel 19 and supplied to the main wheel 4, so that the peaks 23 of the sub wheel 19 are not significantly worn.

A rotating shaft 20A on which the auxiliary wheel 19 can be mounted in the same manner as the rotating shaft 20 is attached to the side plate 2,
2, and can be driven by a drive motor 6 through a gear 35 which is rotatably attached to the end of the side plate 2 and protrudes to the outside of the side plate 2, and can be driven by a drive motor 6 as shown in FIG. For example, a pair of recesses 36, 36 is provided on the rotation shaft 20A at a position where the shaft is mounted, and a gear 35 having a protrusion 38 that can be fitted into the recess 36 is mounted on the shaft hole 37 at this portion, and the rotation shaft 20A is driven by a drive motor. 6 and a play may be provided between the main wheel 4 and the auxiliary wheel 19 driven by the drive motor 6. The recess 36
The and the protruding portion 38 can be mounted with the mounting position reversed.

When the rotating shaft 20A and the like are installed in this manner, the pachinko ball 99 is reliably rotated and fed to the main wheel 4 side even when the sub wheel 19 does not rotate due to insufficient rolling moment of the pachinko ball 99. Can be and recess 3
Since the play of the auxiliary wheel 19 can be made to rotate forward from the main wheel 4 by the play of the protruding portion 38 fitted in the pachinko 6, the pachinko ball 99 can be moved between the auxiliary wheel 19 and the outer wall 34 or between the auxiliary wheel 19 and the auxiliary wheel 19. There is no inconvenience of being locked between the main wheel 4 and the main wheel 4.

Further, similarly to the rotary shaft 20A, the side plate 2,
2 and a rotatable shaft 20B having a normal gear 35A having no protruding portion 38 or the like attached to the end thereof so as to be rotatable with the gear 5 and attached to the end thereof in the circumferential direction as shown in FIG. A cylindrical member 40 having a hole 39 and capable of attaching the auxiliary wheel 19 to the outer surface thereof in the same manner as the rotary shaft 20 is rotatably mounted on the rotary shaft 20B (provided to prevent axial displacement (not shown)). Alternatively, the pin 41 may be screwed onto the rotating shaft 20B, and the cylindrical member 40 may be mounted on the rotating shaft 20B so as to be freely rotatable within a predetermined range.

When the auxiliary wheel 19 is installed on the upstream side of the main wheel 4 in this manner, the same operation and effect as the pachinko doffing apparatus 1 having the configuration shown in FIG. 9 can be obtained.

Further, similarly to the rotary shaft 20B, the side plates 2,
Gear 2 which is rotatably mounted on 2 and mounted on the end
As shown in FIG. 11, a projection 44 and a spring 45 that can be fitted into a concave portion 42 provided on the surface of the rotation shaft are provided on a rotation shaft 20C that can be rotated by the drive motor 6 by 5A. A cylindrical member 4 formed by being fitted into the concave portion 43 so as to be able to protrude by the action of a spring 45 into 46.
0A is mounted, and when the positions of the recesses 42 and 43 match, the projection 44 pushed out by the spring 45
0C, the rotating shaft 20C is fitted with the gear 35A.
When the load is applied to the cylindrical member 40A, the engagement between the projection 44 and the recess 42 is easily disengaged, and the rotation shaft 20 is rotated.
It is also possible to configure so that C can freely rotate with respect to the cylindrical member 40A.

In such a configuration, even when the pachinko ball 99 is not interposed, when the sub wheel 19 is interlocked with the main wheel 4 and the pachinko ball 99 is locked and a strong force starts to act, the force is reduced. The sub-wheel 19 rotates in the direction in which is reduced, so that the pachinko ball 99 does not lock. The recess 42 and the projection 44 may be installed between the gear and the rotating shaft, or the mounting positions may be reversed.

A part of the path for transmitting the rotational force of the drive motor 6 to the auxiliary wheel 19 may be formed with a predetermined play, that is, a gear with a backlash or the like.

It is also possible to hang a shaft between the side walls 2 and 2 so that it cannot rotate, and to rotatably mount a cylindrical member having the auxiliary wheel 19 mounted on the shaft.

Since the present invention is not limited to the above embodiment, various modifications can be made without departing from the spirit of the appended claims.
