Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for lifting a pachinko ball from a low position to a high position, that is, a pachinko ball lift polishing apparatus (hereinafter referred to as “lift polishing apparatus”), and in particular, a spiral body provided in the lift polishing apparatus. It is about improvement.
[0002]
[Prior art]
As a known lift polishing apparatus, there is a lift polishing apparatus disclosed by the present applicant in Japanese Patent Laid-Open No. 11-114199 (hereinafter referred to as “conventional lift polishing apparatus”). A conventional lifting polishing apparatus includes a lifting tower provided with a ball sending unit for discharging pachinko balls at an upper portion, a spiral body rotating in the lifting tower, a spiral groove formed on the outer peripheral surface of the spiral body, a spiral A pachinko ball that is polished while holding the pachinko ball received in the groove, and the pachinko ball lifted by the rotation of the spiral is discharged from the discharge port provided in the ball delivery unit to the outside, It is transported to pachinko machines and players. The lead angle of the spiral groove in the conventional lift polishing apparatus, that is, the inclination of the spiral groove with respect to the horizontal is constant from the lowermost end to the uppermost end, and there has been no idea to change this.
[0003]
On the other hand, in order to allow the pachinko balls to be received in the spiral groove, the smaller the lead angle, the better. This is because the gentler inclination of the spiral groove makes it easier to accept pachinko balls. Therefore, the lead angle of the spiral groove in the conventional lifting and polishing apparatus is set to be relatively small so that the pachinko ball can be smoothly received by the spiral groove, and the spiral groove is formed over the entire length of the spiral body while maintaining the lead angle. .
[0004]
[Problems to be solved by the invention]
However, while the spiral groove having a relatively small lead angle makes it easier to accept the pachinko balls, the length of the spiral groove when the rotating spiral makes one turn is so short that the pachinko balls once received may be congested. In particular, when the rotational speed of the spiral body was increased in order to improve the efficiency of lifting the pachinko balls, there was a strong risk of traffic jams because a large number of pachinko balls were introduced into the short spiral groove. On the other hand, the lifting device may place importance on the lifting efficiency or the polishing efficiency depending on the installation environment, the lifting purpose, and the like. The present invention solves the conflicting requirements of smooth acceptance of pachinko balls by the spiral groove and prevention of traffic jams in the spiral groove all at once, and further, for the installation environment of the lifting device and the lifting purpose. The purpose is to provide an appropriate lifting device.
[0005]
[Means for Solving the Problems]
Therefore, the inventor has achieved the above object by partially changing the lead angle of the spiral groove. The detailed configuration will be described later.

[0009]
(Effects of the invention described in claim 2)
According to the lift polishing apparatus of the second aspect, it is possible to easily manufacture a spiral body having a changing lead angle. For example, in the case where there are three short spirals, a spiral groove with a variable lead angle is formed in one spiral, which is composed of three or four short spirals connected to each other, and is formed in each of the short spirals. This is because it is easier to form spiral grooves having different lead angles .
The same applies when there are four short spirals.

It is a member for doing. As the main material constituting the polishing member 15, a nonwoven fabric is generally used.
[001 4 ]
(Structure of the spiral)
The rotating spiral body 11 can be made of a metal such as aluminum. However, in the present embodiment, it is considered that the spiral body itself is as light as possible, the price is as low as possible, and the processing is as easy as possible. It is made of synthetic resin material. The rotating spiral body 11 is configured by connecting a plurality (four in this embodiment) of short spiral bodies 11p1, 11p2, 11p3, and 11p4 (hereinafter referred to as 11p when the short spiral body is generically referred to). Although the rotating spiral body 11 can be constituted by a single member, the reason why it is constituted by a plurality of members is that processing (manufacturing) and handling are more convenient than such a constitution.
[001 5 ]

That is, the connection plate 11f screwed to the lower end of one short spiral body 11p2 and the connection plate 11f screwed to the upper end of the other short spiral body 11p1 are fastened and fixed by the connection bolt 11b so that they are connected. It has become. Reference numeral 11t denotes a positioning pin that is inserted into a positioning hole 11t formed in the end face of the short spiral body 11p2 and serves to position the short spiral bodies 11p1 and 11p2 when the short spiral bodies 11p1 and 11p2 are connected to each other. Yes. Even when the short spiral body 11p2 and the short spiral body 11p3 are connected to each other, and the short spiral body 11p3 and the short spiral body 11p4 are connected to each other, they can be connected by the same method as described above. As shown in FIGS. 2 and 4, a spiral drive structure 17 is provided at the lower end of the rotary spiral 11. The rotating spiral body 11 is rotationally driven by the drive motor 9 through the spiral body driving structure 17.
[00 16 ]
(Formation of spiral groove)
A spiral groove 13 for receiving a pachinko ball to be lifted is cut and formed on the outer peripheral surface of the rotating spiral body 11. The spiral groove 13 includes a spiral groove 13p1 formed on the outer peripheral surface of the short spiral body 11p1, a spiral groove 13p2 formed on the outer peripheral surface of the short spiral body 11p2, a spiral groove 13p3 formed on the outer peripheral surface of the short spiral body 11p3, and It is constituted by a spiral groove 13p4 formed on the outer peripheral surface of the short spiral body 11p4 so that the lead angle (inclination angle of the spiral groove with respect to the horizontal) increases stepwise from the lower end of the rotary spiral body 11 in the feeding direction. Is formed.
[00 17 ]
Here, the change in the lead angle will be described with reference to FIGS. 2 and 4 to 7. The triangles shown in each of FIGS. 4 to 7 indicate the lead angle of the spiral groove and the length of the spiral groove (groove length). That is, in this embodiment, the lead angle A2 of the spiral groove 13p2 is larger than the lead angle A1 of the spiral groove 13p1, and the lead angle A3 of the spiral groove 13p3 is larger than the lead angle A2 of the spiral groove 13p2. Further, similarly, the lead angle A4 of the spiral groove 13p4 is formed larger than the lead angle A3 of the spiral groove 13p3. As a result, the groove length L1 of the spiral groove 13p1 becomes the shortest groove length, and then becomes longer in the order of the groove length L2 of the spiral groove 13p2, the groove length L3 of the spiral groove 13p3, and the groove length L4 of the spiral groove 13p4. The lead angle (groove length) is formed so as to change stepwise in this way for the convenience of processing the spiral body 11, but each lead of each short cylinder 11p1, 11p2, 11p3, 11p4. The corner is formed so as to increase continuously (gradually) as it goes from the lower end to the upper end, and when these are connected, the lead angle (groove length) is minimized at the lowermost end of the spiral groove 13p1, and the spiral groove 13p4 You may comprise so that a lead angle (groove length) may become the maximum at the uppermost end. The reason for changing the lead angle in four stages is to make the degree of change in the lead angle as small as possible and connect the spiral grooves smoothly.
[00 18 ]
In this embodiment, the lead angle is formed to increase stepwise or continuously from the lower end of the rotating spiral body 11 in the lifting direction. Depending on the purpose of feeding, the lead angle may be partially different in a manner other than the above. If the purpose of lifting is, for example, efficient lifting, it is better to increase the part with a large lead angle in order to shorten the time required for lifting, and if it is efficient polishing, pachinko balls In order to make the contact time of the polishing material as long as possible, it is preferable to increase the portion having a small lead angle. In addition, when the purpose is to improve the introduction efficiency of the pachinko balls at the introduction site of the rotating spiral 11, the lead angle of the spiral groove 13 at this introduction site is set small to facilitate the introduction of the pachinko balls, The lead angle of the spiral groove 13 in the intermediate part other than the introduction part is made larger than the lead angle in the introduction part to shorten the lifting time in this part, and the lead angle is made smaller again at the upper end portion of the rotating spiral body 11 to make the pachinko. You may comprise so that discharge | emission of a ball may be smoothed.
[00 19 ]
(Operational effect of this embodiment)
The effect of this embodiment is demonstrated referring FIG. 2 and 4-7. Pachinko balls P discharged from a pachinko machine, a counter, etc. (not shown) are introduced into the spiral groove 13 at the introduction portion at the lower end of the rotating spiral body 11 through the introduction hole of the short cylindrical body 7. The exposed portion of the pachinko ball P introduced into the spiral groove 13 receives a frictional force from the polishing member 15. The pachinko ball P held by the frictional force and the rotation of the rotating spiral body 11 is polished while being fed in order from the short spiral body 11p1 to the short spiral body 11p2, then to the short spiral body 11p3, and then to the short spiral body 11p4. The lifted pachinko ball P is discharged from the discharge port 32 of the ball delivery unit 31. The rotating spiral body 11 is rotated by the drive motor 9 via the spiral body driving structure 17.
[002 0 ]
At the time of this lifting, the following effects are produced by the fact that the groove lengths L1, L2, L3, and L4 of the spiral grooves 13p1, 13p2, 13p3, and 13p4 are different. That is, since the groove length L2 of the spiral groove 13p2 is longer than the groove length L1 of the spiral groove 13p1 and the number of pachinko balls introduced during one rotation is the same between both grooves, the spiral groove 13p2 is introduced into the spiral groove 13p2. The distance G2 between the pachinko balls P is longer than the distance G1 between the pachinko balls P introduced into the spiral groove 13p1. Similarly, the distance G3 between the pachinko balls P3 introduced into the spiral groove 13p3 is longer than this G2 and the distance G4 between the pachinko balls P4 introduced into the spiral groove 13p4 is longer than this G3.
[002 1 ]
As described above, the spiral groove 13P1 at the introduction site where the pachinko ball P is introduced from the short cylindrical body 7 has a small lead angle A1 (because the inclination is gentle), so In comparison, the introduction is performed smoothly. The distance between the introduced pachinko balls P is the shortest in the spiral groove 13P1 and gradually becomes longer as the spiral groove 13P4 is transported from the spiral groove 13P2 to the spiral groove 13P3. By increasing the distance between the pachinko balls P, the occurrence of the traffic jam is prevented.
[002 2 ]
(Modification of this embodiment)
Based on FIG. 8, a modified example of the present embodiment (hereinafter referred to as “the modified example”) will be described. This modification differs from the above-described embodiment in the way of changing the lead angle. That is, in this embodiment, the lead angle is formed so as to change in four stages of A1, A2, A3, and A4, but in this modification, it is formed so as to change in two stages as described below. ing. That is, the rotating spiral body 111 of the present modification is composed of the shortest spiral body 111p1 at the lowermost stage and the connecting spiral body 111P2 stacked and connected to the upper stage, and the lead angle is formed to change in two stages. .
[002 3 ]
That is, the lead angle A11 of the spiral groove 113p1 formed on the outer peripheral surface of the short spiral body 111p1 is set to be small so that the pachinko balls p can be smoothly introduced. And the lead angle A12 of the spiral groove 113p2 formed in the outer peripheral surface of the connection spiral body 111p2 is set larger than the lead angle A11. The connecting spiral body 111p2 may be a single member or may be configured so that a plurality of short members can be stacked and connected. Therefore, the lead angle changes only between the spiral groove 113p1 and the spiral groove 113p2, and does not change above it. In other words, the lead angle A11 at the lower end portion (short spiral body 111p1) of the rotating spiral body 111 is formed to be smaller than the lead angle A12 at a portion other than the lower end portion (the connecting spiral body 111p2). The effect produced by the change in the lead angle is the same as the effect of this embodiment. That is, since the lead angle A12 of the spiral groove 113p2 is larger than the lead angle of the spiral groove 113p1, the former groove length L12 is larger than the latter groove length L11. Therefore, the distance G12 between the pachinko balls P in the former is larger than the distance G11 between the pachinko balls P in the latter, and the occurrence of traffic jams is prevented.
[002 4 ]
