To be done.

In the pachinko ball delivery device disclosed in Patent Document 1, dirt of pachinko balls is attached to the polishing pellet by causing the pachinko ball and the polishing pellet to be transported by the pumping device in a state where they are joined. And the pachinko balls are polished simultaneously with pumping.
FIG. 6 shows a conventional pachinko ball grinding and pumping apparatus 100 provided in such a pachinko island stand, a storage tank 101a and a storage tank 101b provided on the left and right sides thereof, and an upper tank 102. The pachinko ball polishing and pumping apparatus 100 has a pumping cylinder 110 vertically installed at a substantially intermediate position in the longitudinal direction of the pachinko island stand, and is used for pumping a pachinko ball that is rotationally driven by a motor provided above the pumping cylinder 110. A helical rotary body 111 is provided in the lift cylinder 110, and the lower feed opening of the lift cylinder and the horizontal feed cylinder 113 connected via the elbow 112 are arranged along the longitudinal direction of the pachinko island stand A spiral rotating body 115 for pachinko balls lateral feed rotationally driven by a motor 114 is provided in the lateral feeding cylinder portion 113, and the pachinko balls stored in the storage tank 101a and the storage tank 101b are inclined 樋 116a. , 116b and a pachinko ball flow-in rod 117 provided on one side of the cross-feed tube portion, to flow into the cross-feed tube portion 113, and the inflowing pachinko balls from the cross-feed tube portion 113 It fed into the through raised feed cylinder 110, so that is pumped to the upper tank 102 by the pachinko ball fried feed for spiral rotary member 111 to rotate. Reference numeral 120 denotes a pellet tank, and the abrasive pellet discharged from the tank joins with the pachinko ball at the pachinko ball inflow weir 117, and the joined abrasive pellet passes through the inside of the feeding cylinder 110 together with the pachinko ball and the upper part It is lifted up to the tank 102 and separated from the pachinko ball in the upper tank 102. Then, it is collected and circulated to the pellet tank 120 through the return pipe 121.

  By the way, the pachinko ball polishing and pumping apparatus 100 supplies the pachinko balls smoothly and without delay to the pachinko machines of the pachinko island stand, and at the same time, collects the pachinko balls discharged from the pachinko machines. The storage tank 101a and the storage tank 101b are provided at approximately the middle position in the direction, and the storage tank 101a and the storage tank 101b are provided on the left and right sides thereof. In the conventional pachinko ball polishing and transporting apparatus 100 shown in FIG. The part 113 was provided, and the pachinko ball inflow weir 117 was provided in the cross feed cylinder part 113. Therefore, as shown in the drawing, the distance a between one storage tank 101a and the transport cylinder 110 is significantly longer than the distance b between the other storage tank 101b and the transport cylinder 110. That is, the lifting and lowering barrel 110 can not be disposed equidistantly from the storage tank 101a and the storage tank 101b. It is necessary to keep the inclination angles of the ball collecting rods 123a and 123b and the inclined rods 116a and 116b and the inclination angles of the upper plates 124a and 124b and the bottom plates 125a and 125b in the storage tanks 101a and 101b at a certain angle or more.

The number is further reduced, and there is a problem that it is not possible to store a sufficient amount of pachinko balls required by a large number of pachinko machines.

Furthermore, although the foot insertion space is generally provided at the lower edge of the pachinko island stand so that the player's toe falls under the pachinko island stand during the game, the ranges of the distances a and b are However, if the distance a, b is long, the range in which the foot insertion space can be provided is further limited.

A flange 10b is provided at a portion through which the rotation output shaft 10a of the motor drive unit 9 penetrates. The lower end of the flange 10b is engaged with the engagement groove 20a, and the upper end of the flange 10b is fastened to the flange 7a with a bolt 10c, so that the motor drive unit 9 can move the crossfeed cylinder 7 It is detachably assembled to the As a result, the pachinko ball transverse feeding spiral rotating body 8 provided at the tip of the rotary output shaft 10a is accommodated in the transverse feeding cylindrical portion 7, and the pulsating force of the motor 10 causes the pachinko sphere transverse feeding spiral rotating body. 8 is driven to rotate.

  In addition, the pachinko ball inflow weirs 11a and 11b are provided on both sides of the lateral feeding cylinder portion 7, and the pachinko ball inflow weirs 11a and 11b and the lateral feeding cylindrical portion 7 are in communication with each other. 1a, 1b and the pachinko ball inflow weirs 11a, 11b are connected by the inclined weirs 12a, 12b so that pachinko balls t in the storage tanks 1a, 1b are led to the pachinko balls inflow weir 11a, 11b Do. In addition, electric shutter 13a, 13b is provided in this inclination lever 12a, 12b. In addition, forceps-like filters 14a and 14b for removing foreign matter are provided on the upper surface openings of the pachinko ball inflow gutters 11a and 11b.

Further, an opening 15 is formed on the upper wall surface of the horizontal feed cylinder portion 7, and a pellet tank 16 is provided on the opening, and the abrasive pellet p flows from the pellet tank 16 through the opening 15 into the horizontal feed cylindrical portion 7. I am trying to do it. Abrasive pellets p separated from the pachinko balls t in the upper tank 3 are collected in the pellet tank 16 through the return pipe 17.
Although an overflow pipe for returning the pachinko balls to the storage tank 1a or 1b is provided as needed when the inside of the upper tank 3 is full of pachinko balls, the overflow pipe is not shown.

  In the pachinko ball polishing and pumping apparatus configured as described above, when the pachinko balls t in the storage tanks 1a and 1b are guided to the pachinko ball inflow weirs 11a and 11b through the inclined weirs 12a and 12b, the pachinko balls t are transported laterally.

Collected at 16.

  In the pachinko ball grinding and pumping apparatus according to the present invention, as described above, the transverse feeding cylindrical portion 7 is disposed. Therefore, as shown in FIG. The storage tanks 1a and 1b can be provided symmetrically in the middle, and both storage tanks 1a and 1b can be disposed equidistant from the cross feed cylinder 7. For this reason, it becomes possible to use a common part by right and left, and reduces a manufacturing cost.

  Further, since the transverse feeding tube portion 7 is provided in the direction orthogonal to the longitudinal direction of the pachinko island stand, by removing the waist plate of the portion where the motor drive portion 9 of the pachinko island stand is located, Space is available. Therefore, by removing the bolt 10c and removing the lower edge of the flange 10b from the engagement groove 20a, the motor drive unit 9 can be pulled out to this space together with the pachinko ball lateral feed helical rotating body 8 . Thus, the motor drive unit 9 can be detached by removing the bolt 10 c and removing the flange 10 b from the engagement groove 20 a, as well as sufficient space for pulling out the motor drive unit 9.
