[Means for solving the problems and effects of the invention]
In order to achieve such an object, a pachinko ball launching apparatus according to the present invention is a launching member that strikes and launches a pachinko ball disposed at a launch position of a launch rail as described in claim 1. A pachinko ball passage connecting the prize ball receiving tray and the vicinity of the launch position, and a recess capable of accommodating the pachinko ball, the recess from the receiving position facing the exit of the pachinko ball passage, the recess is the launch position A groove that becomes shallower as it moves away from the recess, at the edge on the rear side with respect to the rotation direction of the transport member toward the transfer position, of the edge of the recess. comprising a conveying member formed, wherein the the firing position a sequential pachinko ball launching device configured so as to supply pachinko balls, the conveying member pachinko ball to the recess is accommodated the delivery When turning toward the position, the pachinko ball to be accommodated in the recess next to the pachinko ball accommodated in the recess is not caught on the edge of the recess, The rear edge is lower than the front edge with respect to the rotation direction of the conveying member toward the delivery position.
[0007]
In the pachinko ball launching apparatus according to the present invention, the pachinko ball is supplied to the launch position on the launch rail as follows. First, the pachinko ball advances from the prize ball tray provided below the game board in front of the pachinko ball launching device through the pachinko ball passage to the vicinity of the launch position (exit of the pachinko ball passage). Then, the conveyance member which has a recessed part which can accommodate a pachinko ball accommodates the pachinko ball in the recessed part at a receiving position (a position where the recessed part faces the pachinko ball supply port). And a conveyance member rotates from a receiving position to a delivery position (position where a recessed part faces a discharge position). Then, the pachinko ball is supplied from the recess to the launch position at the delivery position. And if a pachinko ball is supplied from a recessed part to a launch position, a conveyance member will return to a receiving position. Then, the next pachinko ball is accommodated in the recess.

A pachinko ball passage 16 that connects and disengages the launch cam 12 that pivots the launch rod 12 about the pivot shaft 12b, the prize ball tray (not shown), and the vicinity of the launch position, and the pachinko ball B. Is formed on the side surface, and the recess 17a can freely rotate from a receiving position (see FIG. 1) facing the outlet 16a of the pachinko ball passage 16 to a delivery position (see FIG. 2) where the recessed portion 17a faces the firing position. To axis The cylindrical transport drum 17 is formed, a cam receiving portion 18a is formed at one end, the transport arm 18 is connected to the transport drum 17 at the other end, and the transport arm 18 is attached so that the transport drum 17 is directed to the receiving position. The second coil spring 19 that is energized and the rotation shaft 14a of the firing motor 14 is rotated in one direction, is engaged with and disengaged from the cam receiving portion 18a provided on the conveyance arm 18, and the conveyance arm is centered on the rotation shaft 12b. And a driving cam 20 for rotating the conveying drum 17 by rotating 18, the pachinko ball B is accommodated in the recess 17 a at the receiving position, and the cam receiving portion 18 a provided on the conveying arm 18 is accommodated. When the conveyance drive cam 20 is engaged and disengaged, the conveyance drum 17 is rotated from the receiving position to the delivery position against the urging force of the second coil spring 19, and the recess 1 is formed at the delivery position. After the pachinko ball B is supplied from a to the launch position of the launch rail 11, the conveying drum 17 is rotated to the receiving position by the urging force of the second coil spring 19, and the next pachinko ball B is accommodated in the recess 17a. The pachinko ball is sequentially supplied to the launch position of the launch rail 11.
[0017]
The firing rail 11 and the transport drum 17 are partitioned by a partition wall 21 (not shown in FIGS. 1 and 2), and the pachinko ball B passes through a window portion 21a provided in the partition wall 21 to the transport drum 17 side. To the launch rail side 11.
The conveyance drive cam 20 is configured such that when the conveyance drum 17 moves from the reception position to the delivery position, the rotation speed decreases as the conveyance drum 17 approaches the delivery position. Specifically, as shown in FIG. 3, the closer to the delivery position, the point at which the conveyance drive cam 20 comes into contact with the cam receiving portion 18a of the conveyance arm 18 and the rotation center point of the conveyance drive cam 20 (the firing motor). The distance from the 14 rotation shafts 14a) changes gradually. The rotation speed of the conveyance drum 17 is determined by the point that the conveyance drive cam 20 that is attached to the rotation shaft 14a of the firing motor 14 and rotates at a constant speed in one direction contacts the cam receiving portion 18a of the conveyance arm 18 and the conveyance drive cam. This is because it is approximately proportional to the amount of change in the distance from the 20 rotation center point (the rotation shaft 14a of the firing motor 14).

A groove 17b having a V-shaped cross section is formed at the rear edge of the concave portion 17a and becomes shallower as the distance from the concave portion 17a increases. Specifically, the depth of the groove 17b is about 25% of the diameter of the pachinko sphere B. That is, if the diameter of the pachinko sphere B is X, the depth of the concave portion 17a is about 1.10X, the depth of the groove 17b is about 0.25X, “depth of the concave portion 17a” − “diameter of the pachinko sphere B” "<" Depth of groove 17b ".
[0019]
The conveyance drum 17 and the conveyance arm 18 are connected by inserting a connecting shaft 17 c protruding from the conveyance drum 17 into a long hole 18 b formed in the conveyance arm 18.
Then, the effect | action of the pachinko ball | bowl launching apparatus of a present Example is demonstrated.
[0020]
First, the pachinko ball B travels from the prize ball tray through the pachinko ball passage 16 to the outlet 16a.
Then, the conveyance drum 17 having the concave portion 17a capable of accommodating the pachinko ball B accommodates the pachinko ball B in the concave portion 17a at the receiving position.
[0021]
Then, when the conveyance drive cam 20 attached to the rotation shaft 14a of the firing motor 14 rotates counterclockwise in FIGS. 1 and 2, the conveyance drive cam 20 pushes the cam receiving portion 18a of the conveyance arm 18 and conveys it. The arm 18 rotates clockwise from the position shown in FIG. 1 to the position shown in FIG. 2 against the urging force of the second coil spring 19, and accordingly, the transport drum 17 rotates from the receiving position to the delivery position. .
[0022]
Then, the pachinko balls are supplied from the recess 17a to the firing rail 11 at the delivery position.
When the transport drum 17 rotates from the receiving position to the transfer position, the shape of the transfer drive cam 20 is set so that the rotation speed decreases as it approaches the transfer position, so that the pachinko ball is at the transfer position. It is gently discharged from the recess 17a to the firing rail 11.
[0023]
When the transport driving cam 20 is further rotated, the transport arm 18 is rotated from the position shown in FIG. 2 to the position shown in FIG. 1 by the urging force of the second coil spring 19, and the transport drum 17 is received accordingly. Returning to the position, the next pachinko ball B is accommodated in the recess 17a.
[0024]
When the firing drive cam 15 attached to the rotating shaft 14a of the firing motor 14 as in the case of the transport drive cam 20 further rotates counterclockwise from the position shown in FIG. The 12 cam receiving portions 12a are pushed, and the firing rod 12 rotates clockwise against the urging force of the first coil spring 13 (so-called backswing).
[0025]
When the firing drive cam 15 further rotates, the firing rod 12 rotates counterclockwise by the biasing force of the first coil spring 13 and strikes the pachinko ball B disposed at the firing position of the firing rail 11. Fire. The launch position is about 5 mm downstream from the position of the pachinko sphere B in FIG. 2, and the pachinko sphere B moves from the position shown in FIG. 2 to the launch position while the launcher 12 is backswinging. .
[0026]
By repeating such a series of operations, pachinko balls are sequentially supplied to the launch position of the launch rail 11, and the pachinko balls B arranged at the launch position of the launch rail 11 are sequentially hit by the launcher 12 and fired. Is done.
In this embodiment, the launcher 12 corresponds to the aforementioned launch member.
[0027]
Then, the effect of the pachinko ball launcher of the present embodiment will be described.
When the transport drum 17 is configured to rotate at a constant speed when the transport drum 17 rotates from the receiving position to the transfer position, the pachinko ball B jumps out of the recess 17a vigorously at the transfer position. Although there is a possibility that the firing rail 11 does not stop at the firing position, according to the pachinko ball launching device 1 of the present embodiment, the transport drive cam 20 is configured such that the rotational speed decreases as the transport drum 17 approaches the delivery position. Since the shape is set, the pachinko ball B is gently discharged from the recess 17a to the firing position of the firing rail 11 at the delivery position. Therefore, the pachinko sphere B can be surely stopped at the launch position of the launch rail 11, and thereby the traveling direction and speed of the pachinko sphere B launched by being hit by the launcher 12 can be kept constant. .
[0028]
Also, since the pachinko ball B is transported from the receiving position to the delivery position by the rotation of the transport drum 17, the operation is very smooth.
Of the edges of the recess 17a of the transport drum 17, the rear edge with respect to the rotation direction of the transport drum 17 toward the transfer position is lower than the front edge, and the rear of the recess 17a. Since a groove 17b having a V-shaped cross section that becomes shallower as it moves away from the recess 17a is formed at the edge on the side, it is scheduled to be accommodated in the recess 17a next to the pachinko ball B accommodated in the recess 17a. The pachinko sphere B can move from the state in contact with the pachinko sphere B accommodated in the recess 17a to the rear edge without being caught. Further, the pachinko sphere B to be accommodated in the recess 17a next is smoothly guided along the groove 17b having a V-shaped cross section after being separated from the pachinko sphere B accommodated in the recess 17a. The drum 17 can be smoothly rotated.
