Description

  The present invention relates to a roller used in a roller conveyor device that conveys a gaming machine in an upright posture.

  When assembling a gaming machine, a large space is required when the gaming machine is laid down, so that various parts are assembled in a standing position that is advantageous in terms of space. In addition, various inspections are performed before shipping the gaming machine. In this case, the gaming machine is performed in a standing posture where the gaming machine is actually installed in the hall.

  As described above, when a gaming machine is assembled or inspected in a standing posture, a game in which a guide rail and a roller conveyor are opposed to each other and placed on the roller conveyor in a standing posture as a conveying device for conveying the gaming machine. There has been proposed one that supports and transports the upper part of the machine with a guide rail.

  In the roller conveyor in the transport device, generally equal diameter rollers are used, and when the gaming machine is supported in a standing posture, the movement of the roller in the axial direction cannot be restricted, and a large load is applied to the gaming machine. There is a risk of falling down when the is added. Therefore, it is conceivable to provide a flange (saddle member) on the outer periphery of the roller to restrict the movement of the gaming machine in the roller axial direction, but if the flange is conveyed while being in contact with the side surface of the gaming machine, There is a risk of damage to the gaming machine.

  That is, the present invention has been proposed to solve the above-described problems inherent in the prior art, and is a roller of a roller conveyor device that can stably support a gaming machine without damaging it. The purpose is to provide.

In order to overcome the above problems and achieve the intended purpose, the roller of the roller conveyor device according to the present invention is:
A roller (14) of a roller conveyor device (10) for conveying a gaming machine (16),
A roller body (18) pivotally supported on the conveyor frame (12, 12) and in contact with the gaming machine (16);
It is provided on the outer peripheral surface of the roller body (18) and protrudes in the radial direction, and comprises a gutter member (20, 20) for restricting the movement of the gaming machine (16) in the axial direction of the roller body (18),
On the surface of the saddle member (20, 20) facing the side edge of the gaming machine (16), the side edge of the gaming machine (16) is directed radially outward from the outer peripheral surface of the roller body (18). A taper part (28, 30, 32) spaced from the part is formed.

The tapered portion (28) of the flange member (20) is composed of at least two tapered surfaces (28a, 28b) having different inclination angles with respect to a reference line (L) orthogonal to the axis of the roller body (18). The inclination angle (θ ₁ ) of the first taper surface (28a) on the side close to the machine (16) is set larger than the inclination angle (θ ₂ ) of the second taper surface (28b) separated from the gaming machine (16). Has been.

The inclination angle (θ ₁ ) of the first tapered surface (28a) is set to 20 to 50 °.

  The flange member (20) is composed of a pair of divided halves (22, 22), and is detachably fitted to the roller body (18).

  According to the roller of the roller conveyor device according to claim 1 of the present invention, since the tapered portion is formed on the surface of the saddle member provided on the roller body that faces the side edge portion of the gaming machine, the gaming machine is set in the standing posture. In some cases, when the gaming machine moves in the axial direction of the roller body, it is possible to prevent the gaming machine from falling down by restricting the movement of the gaming machine. Further, since the saddle member does not always contact the side surface of the gaming machine during the transport of the gaming machine, it is possible to suppress the gaming machine from being damaged. Note that even when the gaming machine is laid down, the movement of the gaming machine in the axial direction can be regulated and transported linearly, and damage can be prevented.

  According to the roller of the second aspect, in the taper portion of the saddle member, the first tapered surface having a large inclination angle is provided on the side close to the gaming machine, so that the saddle member is prevented from coming into contact with the side surface of the gaming machine. The damage to the gaming machine is suppressed. In addition, since the second taper surface with a small inclination angle is provided on the side away from the gaming machine, even if a load is applied to the gaming machine and the roller body slides in the axial direction, the second taper surface causes the gaming machine to move in the axial direction. The movement to can be reliably controlled. That is, it is possible to reliably prevent the gaming machine in the standing posture from falling down.

  According to the roller of the third aspect, by setting the inclination angle of the first taper surface in the range of 20 to 50 °, it is possible to further suppress the occurrence of the fall of the gaming machine and the damage. That is, it is advantageous to reduce the tilt angle (20 °) against the fall of the gaming machine, and it is advantageous to increase the tilt angle (50 °) to prevent the gaming machine from being damaged. . Further, according to the roller of the fourth aspect, the position adjustment with respect to the roller main body can be easily performed by configuring the flange member from a pair of divided halves. Further, maintenance such as inspection and cleaning of the eaves member, or replacement when the eaves member is damaged is easy.

  Next, a preferred embodiment of the roller of the roller conveyor apparatus according to the present invention will be described below with reference to the accompanying drawings.

  1 and 2 show a schematic configuration of a roller conveyor device according to an embodiment. The roller conveyor device 10 is rotatable between a pair of conveyor frames 12 and 12 spaced apart in the width direction. A plurality of rollers 14 are arranged in parallel at a predetermined interval in the transport direction, and a gaming machine 16 stands upright substantially vertically with the front and back surfaces in the width direction intersecting the transport direction. Placed in posture. All the rollers 14 are rotated in the same direction by driving means (not shown), and are configured to convey the game machine 16 in a standing posture placed on the roller group. Each roller 14 is pivotally supported between the pair of conveyor frames 12, 12, and is detachably attached to a roller main body 18 with which the lower surface of the gaming machine 16 abuts and an outer peripheral surface of the roller main body 18. It is comprised with a pair of hook members 20 and 20 fitted. The roller body 18 and the saddle member 20 are made of synthetic resin, and preferably coated with a fluororesin or the like on the surface thereof to reduce friction so that the gaming machine 16 or the roller body 18 and the saddle member 20 are damaged. It is recommended to make it difficult to stick.

  The pair of scissors members 20 and 20 are externally fitted to the roller body 18 so as to be spaced apart from each other in the axial direction of the roller body 18 by substantially the same length as the thickness dimension (front-rear direction dimension) of the gaming machine 16. It is comprised so that the lower part of the game machine 16 may face between the heel members 20 and 20. Each flange member 20 is formed in a substantially ring shape as a whole, and its inner diameter dimension is set so as to substantially match the outer diameter dimension of the roller body 18. Further, as shown in FIG. 4, each flange member 20 is composed of a pair of divided halves 22, 22, and is fastened with both halves 22, 22 facing each other with the roller body 18 interposed therebetween. The flange member 20 is fixed to a predetermined position of the roller body 18.

  Since the two halves 22 and 22 have the same configuration and are in an axially symmetrical relationship in the state of being disposed in the roller body 18, only the configuration of the halves 22 located on the upper side in FIG. 4 will be described. The same parts of the half 22 located on the lower side are denoted by the same reference numerals. That is, the half body 22 is formed in a semicircular arc shape, and the radius of the inner peripheral surface thereof is set so as to substantially match the radius of the outer peripheral surface of the roller body 18, and the inner peripheral surface is a roller. It is comprised so that it may closely_contact | adhere to the outer peripheral surface of the main body 18. A plurality of lightening portions 22a are recessed in the inner peripheral surface of the half body 22 so as to be spaced apart in the circumferential direction (see the lower half body 22 in FIG. 4), thereby reducing the weight.

  At both end portions of the half body 22 in the circumferential direction, through holes 22b are formed in parallel with the tangent line, which are opened at the end surfaces in contact with the other half body 22. In addition, a plurality of (four in the embodiment) protrusions 22c project from one end surface in the circumferential direction of the half body 22 so as to surround the through hole 22b, and the other end surface has the through hole. The same number of holes 22d as the protrusions 22c are recessed so as to surround 22b. Then, when the end faces of both halves 22, 22 face each other across the roller body 18, the protrusions 22 c of one half 22 are respectively fitted into the corresponding holes 22 d of the other half 22. At the same time, the corresponding protrusions 22c of the other half 22 are fitted into the holes 22d of the one half 22, respectively, so that the two halves 22 and 22 have corresponding through holes 22b and 22b. Are positioned to align. In this state, the nuts 26 are screwed and tightened to the bolts 24 inserted through the aligned through holes 22b and 22b, whereby the half halves 22 and 22 are positioned and fixed with the roller body 18 sandwiched therebetween.

As shown in FIG. 3, a radial direction from the outer peripheral surface of the roller main body 18 is provided on a surface (one surface in the axial direction) facing the side edge portion (front surface or back surface in the embodiment) of the saddle member 20. A taper portion 28 that is separated from the side edge portion of the gaming machine 16 as it goes outward is formed. The tapered portion 28 is composed of two tapered surfaces 28 a and 28 b having different inclination angles with respect to a reference line L orthogonal to the axis of the roller body 18, and the inclination angle θ of the first tapered surface 28 a on the side close to the gaming machine 16. ₁ is set to be larger than the inclination angle θ ₂ of the second tapered surface 28 b that is separated from the gaming machine 16. That is, by increasing the inclination angle θ ₁ of the first taper surface 28a, the portion (first taper surface 28a) adjacent to the gaming machine 16 of the taper portion 28 is separated from the side surface of the gaming machine 16, so that the gaming machine It is difficult for the 16 side surfaces to come into contact with the tapered portion 28, and scratches and the like can be suppressed. Further, by reducing the inclination angle θ ₂ of the second tapered surface 28b, the portion of the tapered portion 28 that is separated from the gaming machine 16 (second tapered surface 28b) is not greatly separated from the side surface of the gaming machine 16, Even if a load in the thickness direction is applied to the gaming machine 16 and it slides in the axial direction of the roller body 18, the movement of the gaming machine 16 can be reliably restricted by the second tapered surface 28b.

The inclination angle θ ₁ of the first taper surface 28a is preferably set in a range of 20 to 50 ° in order to prevent the gaming machine 16 from falling down and to prevent damage. That is, when priority is given to preventing the gaming machine 16 from falling, the inclination angle θ ₁ is set to be small (20 °), and when priority is given to preventing the gaming machine 16 from being damaged, The angle θ ₁ may be set large (50 °). In order to prevent the gaming machine 16 from falling over and being damaged, it is preferable to set the inclination angle θ ₁ to 30 °.

  Although not shown, the upper part of the gaming machine 16 placed on the roller conveyor device 10 is supported by a guide rail or a roller group similar to the roller conveyor device 10.

(Effects of Example)
Next, the operation of the rollers of the roller conveyor apparatus according to the embodiment will be described. As shown in FIG. 1, the gaming machine 16 is placed on a roller group of the roller conveyor device 10 in a substantially vertical standing posture. At this time, as shown in FIG. 2, the lower surface of the gaming machine 16 abuts on the roller main body 18 facing the pair of flange members 20, 20 in the roller 14. In this state, movement of the lower portion of the gaming machine 16 in the axial direction of the roller body 18 is restricted by the pair of scissors members 20 and 20 that sandwich the gaming machine 16 in the thickness direction. That is, the game machine 16 in a standing posture placed on the roller conveyor device 10 is moved in the axial direction by the hook members 20, 20 even if force is applied in the thickness direction when the game machine 16 is assembled or inspected. The movement is restricted, and the gaming machine 16 can be prevented from falling down and stably supported.

In this case, since the inclination angle θ ₁ of the first tapered surface 28a adjacent to the gaming machine 16 in each of the saddle members 20 is set large (see FIG. 3), when the gaming machine 16 is transported, It is possible to prevent the scissors member 20 from coming into contact with the lower side surfaces (front surface and back surface) of the gaming machine 16 and being damaged. In addition, since the inclination angle θ ₂ of the second taper surface 28b of the saddle member 20 is set small, even if a load in the thickness direction is applied to the gaming machine 16 and it slides in the axial direction of the roller body 18, The movement of the gaming machine 16 can be reliably restricted by the two taper surfaces 28b, and the gaming machine 16 can be prevented from falling down.

  The flange member 20 can be easily removed from the roller body 18 by removing the bolts 24 and 24 and separating the pair of halves 22 and 22. The arrangement position can be easily adjusted. Therefore, for example, even when the middle frame, the game board, etc. are individually transported, it is possible to cope with this by simply adjusting the separation width of the pair of scissors members 20 and 20 with respect to the roller main body 18. There is no need to install it separately. In addition, maintenance such as inspection and cleaning of the eave member 20 is easy, and when the eave member 20 is deformed or damaged, it can be easily replaced.

[Example of change]
The shape of the taper portion 28 in the flange member 20 provided on the roller 14 is not limited to the linear taper surface as in the embodiment. For example, as shown in FIG. You may form so that it may curve. In this case, the game machine 16 can be transported with priority given to preventing the gaming machine 16 from being damaged. Further, as shown in FIG. 6, the tapered portion 32 can be formed to be curved in a convex shape. In this case, priority can be given to preventing the gaming machine 16 from falling down.

  Further, in the embodiment, the case where the tapered portion is configured by two tapered surfaces has been described, but it may be configured by three, four, or five or more having different inclination angles, and in that case, as the distance from the gaming machine increases. It is preferable to make the inclination angle of the tapered surface small.

  In the embodiment, a case has been described in which all the rollers of the roller conveyor device are configured to be rotated by the driving means. However, at least one roller that contacts when the gaming machine is placed may be configured to be rotationally driven. . That is, a configuration may be adopted in which a freely rotating roller is disposed between the positively driven roller and the roller. Furthermore, all rollers can be configured to freely rotate, and can be transported by being manually pressed by an operator when assembly or inspection work is completed.

  In the embodiment, the case where the gaming machine is mainly conveyed in an upright position has been described, but in the roller conveyor device of the present invention, the gaming machine can also be conveyed in a lying position. Even in this case, the saddle members face both sides of the gaming machine placed on the roller body, so that the gaming machine is controlled to move in the axial direction and is stably transported substantially linearly. be able to. Further, at this time, the taper member prevents the saddle member from contacting the side surface of the gaming machine (the surface facing the saddle member when laid down), so that the gaming machine is also prevented from being damaged.
