By the way, the pachinko ball polishing and lifting device 100 supplies the pachinko balls to each pachinko machine on the pachinko island platform without delay, and at the same time, collects the pachinko balls discharged from the pachinko machines in the longitudinal direction of the pachinko island platform. It is arranged at a substantially intermediate position, and storage tanks 101a and storage tanks 101b are provided on both the left and right sides thereof. However, in the conventional pachinko ball polishing and lifting device 100 as shown in FIG. A tubular portion 113 was provided, and a pachinko ball inflow housing 117 was provided in the horizontal feeding tubular portion 113. Therefore, the distance a between one storage tank 101a and the unloading cylinder 110 is significantly longer than the distance b between the other storage tank 101b and the unloading cylinder 110, and the unloading cylinder 110 is combined with the storage tank 101a and the unloading cylinder 110. It was not possible to arrange them equidistantly from the storage tank 101b. It is necessary to keep the inclination angles of the ball recovery gutters 123a, 123b and the inclined gutters 116a, 116b, and the inclination angles of the upper plates 124a, 124b and the bottom plates 125a, 125b in the storage tanks 101a, 101b at a certain angle or more. Therefore, with such an arrangement, the number of pachinko balls that can be actually stored in the storage tank 101a and the storage tank 101b is a substantially triangular space between the bottom plates 125a and 125b and the top plates 124a and 124b in the tank. It is limited to (shown by the shaded area in FIG. 5). Therefore, there is a problem that a sufficient amount of pachinko balls cannot be stored in the storage tank 101a, which has a particularly long distance a.

Note that FIG. 3 of Patent Document 2 shows a pachinko ball lifting device in which the lower portion of the lifting cylinder is curved in an arc shape so that polished pellets and pachinko balls can flow into the lifting cylinder from the lower portion. There is. However, even if the lifting cylinder is curved in this way, the above-mentioned imbalance is not eliminated, so that a sufficient amount of pachinko balls cannot be stored in the storage tank 101a.

Further, in such a conventional pachinko ball polishing and lifting device, the pachinko balls and the polishing pellets are not uniformly dispersed in the lifting cylinder, and the pachinko balls are agglomerated to put an excessive load on the spiral rotating body. Since the hooking and frictional resistance also increase, there is a risk of causing transportation troubles.
The present invention attempts to solve these problems.

Therefore, in the pachinko ball polishing and lifting device according to the present invention, a lifting device main body is provided at a substantially intermediate portion in the longitudinal direction of the pachinko island platform, and the pachinko ball polishing and lifting device is provided from a pair of storage tanks provided on both sides of the lifting device main body. A pachinko ball polishing and lifting device that allows pachinko balls to flow into the main body of the lifting device and lifts the pachinko balls to the upper tank. Is vertically supported, the lower part of the pachinko machine is formed into a curved shape that gently curves in the direction orthogonal to the longitudinal direction of the pachinko island platform, and the polishing pellets are placed on the upper side of the curved lower part of the pachinko machine. A pellet tank for storage is arranged, an inflow port is opened on the upper surface of the lifting cylinder below the pellet tank, and a pair of pachinko ball inflow housings are provided on both sides of the inflow port, and the storage tank is provided. The pachinko balls that flowed out from the pachinko balls were allowed to flow into the inflow port from the pachinko ball inflow case, and the polished pellets that flowed out from the lower edge of the pellet tank and the pachinko balls were mixed at the inflow port. It is characterized by that.

Further, in the above-mentioned pachinko ball polishing and lifting device, the lower portion of the lifting cylinder is gently curved over a width of 400 mm to 700 mm in a direction orthogonal to the longitudinal direction of the pachinko island platform with a radius of curvature of 600 mm to 1200 mm. It is characterized in that it is formed in a curved shape.

Further, in the pachinko ball polishing and lifting device, the present invention is formed by cutting off the upper half of the peripheral wall at the lower end of the lifting cylinder, and the upper portion of the inflow port is the pachinko ball inflow housing. A pellet inflow throat having a pair of vertical plate portions extending above the inflow port is provided at the pellet outflow port formed at the lower edge of the pellet tank, and is surrounded by the side wall and the surrounding wall. It is characterized in that pachinko ball inflow portions are formed on both sides of the throat.

Further, the present invention is characterized in that, in the pachinko ball polishing and lifting device, the surrounding wall is provided so as to be openable and closable, and the polishing pellets can be discharged to the outside for replacement by opening the surrounding wall.
Further, the present invention is characterized in that, in the pachinko ball polishing and lifting device, the spiral rotating body is rotationally driven by a motor provided at the upper end of the lifting cylinder.

According to the present invention, since the storage tanks can be arranged at short distances on both sides of the pachinko ball polishing and lifting device, a sufficient amount of pachinko balls can be stored in each storage tank. Further, since the pachinko balls flow into the inflow port of the lifting cylinder from both sides and the polishing pellets flow in between them, the polishing pellets are evenly mixed with the pachinko balls without being biased to one side. For this reason, the contact between the pachinko balls is relaxed, and the problem that the pachinko balls become lumps and exert an excessive load on the spiral rotating body to cause troubles is solved, and the polishing action of the pachinko balls by the polishing pellets is eliminated. Is also demonstrated.

The upper portion of the lifting cylinder 4 is inserted into the upper tank 5, and the upper end 4a of the lifting cylinder 4 is opened at a higher position than the sunoco-shaped filter 11 provided in the upper tank 5. Then, a spiral rotating body 12 formed by forming steel wires in a coil shape at a pitch of 44 mm is arranged inside the lifting cylinder 4, and the spiral shape protruding upward from the upper end 4a opening of the lifting cylinder 4. The rotation output shaft of the motor 13 with a speed reducer is connected to the upper end of the rotating body 12 so that the spiral rotating body 12 can be rotationally driven in a predetermined direction. The slatted filter 11 is for separating the pachinko ball and the resin pellet. The resin pellet having a diameter smaller than that of the pachinko ball falls from the slatted filter 11, and the dropped resin pellet flows down the pellet return pipe 14. It is collected in the pellet tank 15 described later. Further, in the upper tank 5, the upper storage chamber 17 and the lower overflow chamber 18 are formed by providing the partition plate 16, and the storage chamber 17 and the overflow chamber 18 are communicated with each other by an overflow cylinder 19 provided vertically. ing. Further, the upper tank 5 is provided with a ball discharge port 20 for supplying balls to adjacent islands on both sides and a ball receiving port 21 for receiving balls from adjacent islands. Then, the rectifiers 6a and 6b are provided on both side walls of the storage chamber 17, and the pachinko balls stored in the storage chamber 17 are supplied to each pachinko machine on the pachinko island stand via the rectifiers 6a and 6b. Further, the overflow pipe 7 is connected to the bottom of the overflow chamber 18.

The lower portion 4b of the lifting cylinder 4 is formed in a curved shape that is gently curved in a direction orthogonal to the longitudinal direction of the pachinko island platform, and the pellet tank 15 for storing the polishing pellets is arranged above the lower portion 4b. Then, an inflow port 22 is opened on the upper surface of the lifting cylinder 4 below the pellet tank 15, and a pair of pachinko ball inflow casings 23a and 23b are provided on both sides of the inflow port 22, and the storage is described. The pachinko balls that have flowed out of the tanks 2a and 2b are allowed to flow into the pachinko ball inflow casings 23a and 23b through the inclined gutters 3a and 3b. Ball outlets 24a and 24b are formed on the side wall surfaces of the pachinko ball inflow casings 23a and 23b facing the inflow port 22, respectively, and at the lower edge of the pellet tank 15 at a portion facing the inflow port 22. Is formed with a pellet outlet 25. Further, in the upper part of the inflow port 22, a surrounding wall 26 is formed so that the polishing pellets flowing out from the pellet outflow port 25 and the pachinko balls flowing out from the ball outflow ports 24a and 24b do not spill out. Then, the surrounding wall 26, the lifting cylinder 4, and the lower part of the upright frame 10 are supported on the assembly plate 27. A bearing 28 is provided at the lower end of the lifting cylinder 4, and the lower end of the spiral rotating body 12 is rotatably supported by the bearing 28. A hose for collecting dust (not shown) is connected to the pellet return pipe 14, and the dust in the pellet return pipe 14 is vacuum-sucked into the dust collector 14a shown in FIG.

In the pachinko ball polishing and lifting device configured in this way, the ball outlets 24a and 24b of the pachinko ball inflow casings 23a and 23b face each other on both sides of the inflow port 22 formed on the upper surface of the lower portion 4b of the lifting cylinder 4. Therefore, the pachinko balls flow into the inflow port 22 from both sides, and at the same time, the polished pellets flowing out from the pellet outflow port 25 flow into the inflow port 22 from between. Therefore, the pachinko balls and the polishing pellets are evenly mixed without being biased to one side, and the spiral rotating body 12 is rotationally driven by the motor 13, so that the pachinko balls and the polishing pellets are uniformly mixed in the lifting cylinder 4. The pachinko balls are not overloaded on the spiral rotating body 12 and the pachinko balls and the polishing pellets are not carried together. Since the contact is ensured, the pachinko balls are polished very cleanly by this lifting.

Further, the lower portion 4b of the lifting cylinder 4 is formed in a curved shape that is gently curved in a direction orthogonal to the longitudinal direction of the pachinko island platform, and is formed on both sides of an inflow port 22 provided on the upper surface of the lifting cylinder. A pair of pachinko ball inflow casings 23a and 23b are provided, and the pachinko balls that have flowed out from the storage tanks 2a and 2b are allowed to flow from the pachinko ball inflow casings 23a and 23b into the inflow port 22. Storage tanks 2a and 2b can be arranged at short distances on both sides of the ball polishing and lifting device 1. Therefore, the pachinko balls stored in the storage tanks 2a and 2b can be easily guided to the inflow port 22 of the lifting cylinder 4 by rolling the inclined gutter by its own weight, and a sufficient amount of pachinko balls can be stored in each of the storage tanks 2a and 2b. It can be stored in tanks 2a and 2b.
Further, pachinko ball inflow casings 23a, 23b, inclined gutters 3a, 3b, etc. are provided symmetrically on both sides of the lifting cylinder 4 in the middle, and both storage tanks 2a, 2b are equidistant from the lifting cylinder 4. Since it can be arranged, it is possible to use common parts on the left and right, reducing the manufacturing cost.

Then, the pachinko balls lifted to the upper tank 5 pass over the gutter-shaped filter 11 and are stored in the storage chamber 17, and are supplied from the storage chamber 17 to each pachinko machine on the pachinko island stand and adjacent to each other. When the shortage balls are supplied to both islands and the storage chamber 17 is filled with pachinko balls, the balls flow into the lower overflow chamber 18 through the overflow cylinder 19, the overflow pipe 7, the conversion box 8, and the ball collection gutter. It is returned to the storage tanks 2a and 2b via 9.

(Example 2)
Next, a preferred embodiment of the lifting cylinder 4 shown in the first embodiment will be described in more detail with reference to FIGS. 7 to 10 as the second embodiment. As shown in FIG. 8, the lifting cylinder 4 shown in the second embodiment is gently curved with a radius of curvature R of the lower portion 4b of 600 mm to 1200 mm (most preferably 900 mm) in the longitudinal direction of the pachinko island platform. The width (island width) W in the direction orthogonal to is formed in a curved shape so as to extend from 400 mm to 700 mm (most preferably 500 mm). In this way, by setting the degree of curvature determined by the radius of curvature R and the width W of the lower portion 4b of the lifting cylinder 4, polishing pellets and pachinko balls are provided at the inflow port 22 provided at the lower end of the lifting cylinder 4. Can be easily flowed in, and the stress associated with the rotation of the spiral rotating body 12 arranged in the lifting cylinder 4 can be reduced. That is, by setting the radius of curvature R and the width W within the above ranges, it is possible for the abrasive pellets and pachinko balls to flow into the inflow port 22 while minimizing the stress associated with the deformation of the spiral rotating body 12 during rotation. It can be opened upward at the angle of.
Further, by reducing the stress associated with the rotation of the spiral rotating body 12 in this way, the spiral rotating body 12 can be smoothly rotated by only one motor 13 provided at the upper end portion of the lifting cylinder 4. It becomes possible to drive.

The inflow port 22 is formed by cutting off the upper half of the peripheral wall at the lower end of the lifting cylinder 4, and the upper part of the inflow port 22 is a side wall and a plate-shaped pachinko ball inflow casing 23a, 23b. It is surrounded by a wall 26. The surrounding wall 26 is fastened so that it can be opened and closed by tightening screws 29 on both side edges.
Further, a pellet inflow throat 30 having a pair of vertical plate portions 31a and 31b extending above the inflow port 22 is provided at the pellet outflow port 25 formed at the lower edge portion of the pellet tank 15. Then, pachinko ball inflow portions 32a and 32b are formed on both sides of the pellet inflow throat 30.

By providing the pellet inflow throat 30 in this way, the polished pellets flowing out from the pellet tank 15 are guided directly above the inflow port 22, and the pachinko balls flowing out from the ball outflow ports 24a and 24b are used for the pellet inflow. Since the pachinko balls are guided so that they can flow into the inflow port 22 from both sides of the throat 30, the force of one pachinko ball does not interfere with the inflow of the polishing pellets, and the balance is always maintained evenly for polishing. Pellets and pachinko balls can flow into the inflow port 22.
As a result, the pachinko balls are always lifted and polished smoothly.

Generally, since the polishing pellets are worn by use, they need to be replaced regularly. In that case, the polishing pellets can be discharged to the outside by loosening the screw 29 and removing the surrounding wall 26, and the surrounding wall 26 can be discharged to the outside. Since the direction is opposite to the passage between the pachinko islands, such pellet exchange work can be easily performed from the passage.
The surrounding wall 26 is provided with a hinge on one side edge to support it so that it can be opened and closed, and an engaging member that can be engaged and disengaged is provided on the other side edge so that the surrounding wall 26 can be opened and closed by removing the engaging member. Alternatively, slide members may be provided on both side edges of the surrounding wall 26, and the surrounding wall 26 may be provided so as to be slidable so that the surrounding wall 26 can be easily opened and closed. In short, a means for fixing the surrounding wall 26 so as to be openable and closable can be appropriately considered.
