Description

[0001]
[Industrial applications]
The present invention relates to a game ball lifting device that supplies game balls to a predetermined height in a pachinko hall.
[0002]
[Prior art]
In recent pachinko halls, pachinko machine yards (called "islands" because they are scattered in the pachinko halls), in which a group of pachinko machines are installed outward, are arranged in parallel. A game ball lifting device is used in which a game ball discharged from each pachinko machine is recovered, polished, lifted to a predetermined height, and supplied again to a game ball replenishment path of each pachinko machine.
[0003]
Inside the pachinko machine yard, there is provided a storage tank whose bottom plate is inclined downward toward the game ball lifting device. In this storage tank, a predetermined number of game balls are stored in advance in order to increase the absolute amount of game balls circulating in the pachinko machine yard, and the game balls stored in the storage tank pass through a passage formed downstream of the storage tank. Is ground by the game ball lifting device, transported to the upper part of the pachinko machine yard, and returned to the storage tank again after passing through each pachinko machine.
[0004]
By the way, in a conventional game ball lifting device, a flexible body that holds a game ball between the endless belt and imparts a lifting force to the game ball is attached to an openable and closable door arranged opposite to the endless belt. Material. That is, as shown in FIG. 6, the flat flexible body 200 is set to have substantially the same width as the distance between the two side plates 211A and 211B of the door 210 having a horizontal U-shaped cross section. Had been stuck to. The flexible body 200 thermally expands due to an increase in the ambient temperature of the game ball lifting device or frictional heat generated by friction between the game ball PB and the flexible body 200 during the game ball PB lifting. Due to this thermal expansion, the flexible body 200 is curved and lifts up, and becomes a hindrance for the game ball PB. That is, the gap between the flexible body 200 and the endless belt (not shown) is set in advance so as to provide an elastic force that does not suppress the lifting of the game ball PB, but when the flexible body 200 is curved and floats, The game ball PB is further urged toward the endless belt side, and the elastic force greater than the preset value is applied to the game ball PB, so that the running of the game ball PB is obstructed and the game ball PB is not smoothly lifted. This may cause abnormal wear of the flexible body 200 itself.
[0005]
Further, since the flexible body 200 is formed in a flat plate shape, the game ball PB is pressed toward the endless belt only by the elastic force of the flexible body 200.
[0006]
Further, the flexible body 200 is attached to the door 210, while the game balls PB are in contact with the side plates 211A and 211B serving as guides for limiting the widthwise movement of the game balls PB formed of, for example, a soft synthetic resin. Due to the lifting, the side plates 211A and 211B have a problem such as partial wear.
[0007]
[Problems to be solved by the invention]

Then, the pachinko balls PB are sandwiched between the lifting belt 25 and the pachinko balls PB are arranged at a position where a lifting force is applied to the pachinko balls PB.
[0025]
The upper and lower doors are configured so that an ordinary adult can reach the upper end of the polishing cloth 90 without using a stepladder or the like in order to facilitate replacement of the polishing cloth 90. is there. That is, since the height of the game ball lifting device 10 is set in advance so that the pachinko balls PB can be conveyed to the upper part of the pachinko machine yard and naturally flow down, the height of the door in the vertical direction is considerably high. Become. Therefore, the length of the polishing cloth 90 (the length in the vertical direction of the lower door 68) can be reached at its upper end without a normal adult using a stepladder or the like, and while the pachinko ball PB is lifted sufficiently. The degree of polishing is limited, and the portion higher than this height sends the pachinko balls PB to the discharge chute 42, that is, the soft elasticity that sandwiches the pachinko balls PB with the lifting belt 25 and applies a lifting force to the pachinko balls PB. A body 71 is provided, and doors are configured in two stages up and down so as to correspond thereto. Since the soft elastic body 71 imparts a lifting force to the pachinko balls PB as described above, the number of replacements is smaller than that of the polishing pad 90.
[0026]
The upper and lower doors 66 and 68 are provided with a plurality of vertically L-shaped hook portions 85A which constitute one of fasteners for holding the closed state of the upper and lower doors 66 and 68 on the side plate 67B opposite to the hinge 65B.

As shown in FIG. 3, locking means for guiding the upward insertion of the flexible elastic body 71 near the side plates 67A and 67B and restricting the movement in the width direction are provided on both sides inside the upper door 66. The two guide rails 74 are respectively arranged. As shown in FIG. 3, these guide rails 74 are provided with rising portions 74 </ b> A that are a part of locking means that rise from the portion fixed to the upper door 66 at right angles in the direction of the lifting belt 25. . The leading end of the rising portion 74A serves as a holding portion 74B which is bent at a right angle in a direction approaching each other and is a part of the locking means opposed to each other.
[0028]
As shown in FIG. 3, a soft elastic body 71 is inserted upward (in the direction of the arrow UP) between the rising portions 74A of the pair of guide rails 74. As shown in FIG. 2, holes 84 forming a part of the mounting means are formed in the lower end of the upper door 66 near both ends in the width direction. That is, a plate-like fixture 80 constituting another part of the mounting means shown by the broken line in FIG. 2 is penetrated through the lower end of the flexible elastic body 71 along the width direction of the flexible elastic body 71. As shown in FIG. 3, holes 80A are formed at both ends of the fixture 80 at positions corresponding to the holes 84 constituting the mounting means of the upper door 66. A bolt 81 constituting another part of the mounting means is inserted into the hole 80A of the fixture 80 and the hole 84 of the upper door 66, and fastened with a nut 82 from the opposite side (arrow FR side) of the upper door 66. Note that the mounting means is disposed at the lower ends of the upper door 66 and the flexible elastic body 71 because the upper door 66 is simply opened without removing the upper door 66 from the base column 50 (see the two-dot chain line in FIG. 2). In this state, an ordinary adult can insert and remove the flexible elastic body 71 from below into the guide rail 74 without using a stepladder or the like, and fix and remove the flexible elastic body 71 with bolts 81 and nuts 82.
[0029]
As shown in FIGS. 3 and 4, the flexible elastic body 71 has a flat plate shape, and is a trapezoidal projection whose front end (in the direction of arrow FR) that abuts on the back surface of the upper door 66 is tapered. A plurality of contact portions 73A are formed linearly at appropriate intervals along the transport direction (vertical direction) of the pachinko balls PB. That is, a plurality of contact portions 73A are formed separately from each other on the surface facing the back surface of the upper door 66, and contact the upper door 66. Therefore, the flexible elastic body 71 is separated from the upper door 66 in a portion between these contact portions 73A, and the pachinko balls PB are elastically moved between the soft belt 71 and the lifting belt 25 together with the elasticity of the flexible elastic body 71. The elasticity for pinching is generated.
[0030]
The rear surface (in the direction of arrow RE) of the flexible elastic body 71 is a running surface 73B of the pachinko ball PB facing the lifting path PW, and guide surfaces 73C as guide portions are formed at both ends in the width direction. ing. As shown in FIGS. 3 and 4, the guide surface 73C is an inclined surface that gradually approaches the lifting belt 25 from the flat running surface 73B. At the end of the guide surface 73C, a projection 72, which is an engaging means projecting in the width direction, is provided so as to project toward the side plates 67A and 67B of the upper door 66. That is, as shown in FIG. 3, the protrusion 72 is formed at a position shifted from the extension of the running surface 73B in the width direction toward the lifting belt 25. Therefore, as shown in FIG. 3, when the projection 72 of the flexible elastic body 71 is engaged with the rising portion 74A of the guide rail 74 of the upper door 66, the side surface 71A of the flexible elastic body 71 and the side surface 71A are opposed to each other. The guide rail 74 is disposed such that a gap D is formed between the guide rail 74 and the rising portion 74A. The gap D is for absorbing thermal expansion due to a temperature change and preventing the flexible elastic body 71 from rising toward the lifting belt 25.
[0031]
As shown in FIG. 2, two guide rails 76 for guiding the insertion of the polishing pad 90 are disposed on both sides inside the rear surface of the lower door 68 near the side plates 67A and 67B. At the lower end of the polishing cloth 90, a pocket-shaped hook 92 is formed. The hook portion 92 is formed by sewing both ends in the width direction of the polishing cloth 90 with a sewing thread 90A along the longitudinal direction in a state where the lower end of the polishing cloth 90 is bent. At the lower end of the lower door 68, notches 77 are formed at both ends in the width direction, and the lower end of the lower door 68 between these notches 77 is a protruding piece 68A. The polishing cloth 90 covers the hook portion 92 on the protruding piece 68A and locks the lower end side of the polishing cloth 90 to the lower door 68.
[0032]
As shown in FIGS. 1 and 2, a stopper 96 is disposed outside the vicinity of the upper end of the lower door 68. The stopper 96 is a plate member formed in a U-shape in horizontal section so as to cover the outside of the lower door 68, and is fixed by threading a pair of bolts 96 </ b> B to both ends of the stopper 96 and screwing to the lower door 68. I do. That is, the upper end portion 95 is folded back at the upper end of the lower door 68 in a state where the hook portion 92 is hooked on the lower door 68, and is fixed by being sandwiched between the stopper 96 and the lower door 68. Therefore, as shown in FIGS. 1 and 2, the length of the polishing pad 90 is set to be slightly longer than the length of the lower door 68 in the vertical direction.
[0033]
Next, the attachment and detachment of the soft elastic body 71 and the polishing pad 90 according to the present embodiment at the time of replacement will be described.
[0034]
In order to attach the flexible elastic body 71 to the upper door 66, for example, the projections 72 on both sides of the flexible elastic body 71 in the guide rail 74 of the upper door 66 in a state where the upper door 66 is opened (the state of the imaginary line in FIG. 2). And the flexible elastic body 71 is inserted upward from below. As shown in FIG. 3, the flexible elastic body 71 is inserted to a position where the fixture 80 corresponds to the hole constituting the mounting means of the upper door 66, and the hole of the fixture 80 of the flexible elastic body 71 and the upper door 66 are formed. A bolt 81 is inserted into the hole of the mounting means and fastened with a nut 82 from outside the upper door 66.
[0035]
The removal of the flexible elastic body 71 is performed by a procedure reverse to the procedure of the above-described attachment. That is, the flexible elastic body 71 is removed by opening the upper door 66, then removing the bolt 81 fastening the fixing member 80 of the flexible elastic body 71, and moving the flexible elastic body 71 downward along the guide rail 74. Perform by pulling out.
[0036]
In order to attach the polishing cloth 90 to the lower door 68, for example, as shown in FIG. 2, with the lower door 68 opened, the polishing cloth 90 is made to correspond to both sides of the polishing cloth 90 between the guide rails 76 of the lower door 68. Is inserted between the guide rails 76. In this case, the hook 92 of the polishing cloth 90 is set to a position below the protruding piece 68A of the lower door 68, and after inserting the polishing cloth 90 into the guide rail 76, the polishing cloth 90 is pulled up. 92 is put on the projection 68A and locked. This insertion prevents the polishing pad 90 from coming off the guide rail 76, specifically, prevents the polishing pad 90 from being turned up and raised. Since both sides of the polishing pad 90 are engaged with the guide rails 76, the lower door 68 can be more reliably locked in the left-right direction.
[0037]
1 and 2, the upper end 95 of the polishing pad 90 is folded back at the upper end of the lower door 68. After the folded upper end 95 is pulled downward to apply tension to the polishing cloth 90, that is, in a state where the polishing cloth 90 is not loosened, the upper end 95 is moved to the stopper 96 and the lower door 68 as shown in FIG. It is fixed by sandwiching it between. The stopper 96 fixes the stopper 96 with the bolt 96B while sandwiching the upper end 95.
[0038]
The removal of the polishing cloth 90 is performed by a procedure reverse to the above-described procedure of attachment. That is, to remove the polishing cloth 90, after the lower door 68 is opened, the bolt 96B is loosened and the stopper 96 is lifted to release the locked state of the upper end 95 of the polishing cloth 90. The polishing cloth 90 on the back side of the lower door 68 is pulled out downward along the guide rail 76, and is released from the lower door 68 by releasing the locked state between the projection 68A and the hook 92 of the polishing cloth 90. After the replacement of the soft elastic body 71 and the polishing cloth 90, the upper and lower doors 66, 68 are held in the closed state by the fasteners 85A, 85B.
[0039]
The replacement of the soft elastic body 71 and the polishing cloth 90 is based on the cylindrical portion 65B forming the hinge by removing the upper and lower doors 66, 68, that is, by lifting the upper and lower doors 66, 68 as shown by the solid line in FIG. It may be performed after the column 50 is pulled out from the support portion 65A.
[0040]
After the replacement of the soft elastic body 71 and the polishing cloth 90, the lower roller 20 is rotated clockwise by driving the motor 60 to draw the pachinko balls PB between the lifting belt 25 and the biting chute 40, and play the game balls. It is sent forward and upward of the lifting device 10. That is, the pachinko balls PB are sandwiched between the lifting belt 25 and the polishing cloth 90, and are lifted while being polished (sliding and rotating) by the polishing cloth 90.
[0041]
Further, as shown in FIG. 3, when the pachinko ball PB is lifted up to the flexible elastic body 71, the pachinko ball PB is sandwiched and lifted between the lifting belt 25 and the flexible elastic body 71 and is discharged from the discharge chute 42. Is discharged.
[0042]
Therefore, in this embodiment, even when the flexible elastic body 71 thermally expands due to a temperature change, the thermal expansion escapes due to the gap D, so that the floating of the flexible elastic body 71 can be prevented, and the pachinko ball PB runs smoothly.
[0043]
Further, in the present embodiment, since the flexible elastic body 71 is separated from the upper door 66 in the portion between the contact portions 73A of the flexible elastic body 71, the elastic belt 71 An elastic force for elastically holding the pachinko ball PB is generated between them, and the elastic force of the flexible elastic body 71 can be improved.
[0044]
Further, in the present embodiment, since the guide portion 73C is formed on the running surface 73B side of the flexible elastic body 71, the pachinko balls PB at the time of unloading interfere with the holding portion such as the guide rail 74 for holding the flexible elastic body 71. Therefore, friction between the pachinko ball PB and the guide rail 74 or the door can be prevented.
[0045]
In the present embodiment, it is not necessary to fix or peel the flexible body with an adhesive as in the related art, and the replacement of the flexible elastic body 71 can be facilitated.
[0046]
Further, since the guide portions 73C are formed only at both ends in the width direction of the flexible elastic body 71, unlike the case where the lifting path PW is partitioned, the pachinko balls PB freely run between the guide portions 73C, The ball PB and the lifting belt 25 and the flexible elastic body 71 are in random contact, wear and fatigue are dispersed, and the replacement cycle and life of the lifting belt 25 and the flexible elastic body 71 are extended. Further, since the wear and fatigue of the flexible elastic body 71 and the lifting belt 25 are dispersed, the pachinko balls PB run smoothly and lead to the maintenance of the lifting ability.

Notches 102A are provided at appropriate intervals in the length direction of the contact portion 102, and the contact portion 102 is cut off by the notch 102A. Further, the contact portions 102 are provided in a plurality of rows so as to protrude along the transport direction at appropriate intervals, and are arranged in parallel.
[0049]
FIG. 5C shows a fourth embodiment, in which the abutting portion 104 has a substantially rectangular planar shape and rounded corners. A plurality of rows of the contact portions 104 are protruded such that the length direction of the contact portions 104 is orthogonal to the transport direction, that is, the contact portions 102 in FIG. 5B are rotated by 90 degrees. Further, the contact portions 104 are arranged with their vertical positions shifted in adjacent rows in the width direction of the flexible elastic body 71.
[0050]
FIG. 5D shows a fifth embodiment, in which the contact portion 106 is formed in a truncated cone shape. The contact portions 106 are arranged at appropriate intervals along the transport direction, and also in the width direction of the flexible elastic body 71, a plurality of rows, that is, five rows in this embodiment, are arranged at appropriate intervals. In the rows adjacent to each other in the width direction of the flexible elastic bodies 71, the positions in the up-down direction are shifted.
[0051]
In each of the above embodiments, the contact portions 100 to 106 are formed integrally with the flexible elastic body 71. However, the contact portions 100 to 106 are separately formed and fixed to the flexible elastic body 71 with an adhesive or the like. Is also good. Other configurations, functions and effects are the same as those of the first embodiment.
[0053]
【The invention's effect】
Since the present invention is configured as described above, even when the flexible body thermally expands due to heat generated at the time of playing the game ball, the thermal expansion portion is formed by the gap between the side surface of the flexible body and the locking means corresponding to this side surface. Since it is absorbed, the bending of the flexible body due to thermal expansion can be prevented, and the running of the game ball can be smooth.
[0054]
In addition, since the present invention is configured as described above, the flexible body is separated from the support member at the portion between the protrusions of the flexible body, so that the game ball is elastically moved between the flexible body and the endless belt in combination with the elastic force of the flexible body. An elastic force for pinching the elastic member is generated, and the elastic force of the flexible body can be improved.
[0055]
Further, since the present invention is configured as described above, the amount of movement of the game ball in the width direction by the guide portion is limited, so that the game ball does not interfere with other members and friction between the game ball and other members is generated. Can be prevented.
