Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cloth pachinko ball conveying and polishing apparatus for a game type that stably conveys and polishes the amount of pachinko balls flowing into the conveying and polishing apparatus in a game pachinko ball conveying and polishing apparatus.
[0002]
[Prior art]
Conventionally, as a technique related to a pachinko ball lifting and polishing apparatus, in general, an endless lifting belt is provided on one surface of a lifting path, and an abrasive such as paper or cloth having polishing ability is provided on the other surface. A guide rail made of an elastic material in which a plurality of substantially semicircular concave grooves slightly larger than the diameter of the pachinko ball are formed on the back surface thereof is fixed to the sandwiching plate via a spring or the like, and the feeding belt, abrasive and guide 2. Description of the Related Art There is a known lift polishing apparatus that interposes pachinko balls between rails and performs polishing while driving the lift belt to lift the pachinko balls. In this lifting and polishing apparatus, in order to increase the contact area between the pachinko balls and the abrasive, the guide rails that are elastically deformable so as to follow the pachinko balls being lifted are sandwiched via springs or the like. Therefore, if the pachinko ball clamping pressure is increased to obtain a high polishing ability, the guide rail will bend and the pachinko ball will be held in the concave groove, and the intended clamping pressure can be obtained. The pachinko ball does not rotate well because the frictional force with the abrasive becomes large, and the pachinko ball is not polished well as a whole, or the pachinko ball stays in the ball path, In some cases, it caused biting and hindered transportation. In order to prevent the ball biting of such a lifting and polishing apparatus, there is a pachinko ball lifting and polishing apparatus in which the clamping plate is formed of a high-rigidity resin plate (see, for example, Patent Document 1).
[0003]
In this conventional lifting and polishing apparatus, since the clamping plate is formed of a highly rigid resin plate that is difficult to elastically deform, even if the clamping pressure of the pachinko ball is increased, there is little deformation of the clamping plate. Since the contact area with the abrasive is not increased, and this can reduce the increase in friction, it is difficult to cause retention due to increased friction in the ball path of the pachinko balls, so that no ball biting occurs. It has the characteristic to do.

[Problems to be solved by the invention]
However, in the conventional lifting and polishing apparatus in which the sandwiching plate is formed of a high-rigidity resin plate, a high-rigidity resin plate that is difficult to be elastically deformed is used as the sandwiching plate, so that ball engagement due to elastic deformation of the sandwiching plate does not occur. However, there is a problem that it is not possible to adequately deal with ball biting prevention measures due to causes other than elastic deformation. For example, depending on the speed of the lifting belt, the amount of ball trapping that flows into the lifting and polishing device In some cases, however, there is a risk that the pachinko balls that are brought into close contact with each other and bite the pachinko balls that are transported are in danger of being constrained. That is, when the speed of the lifting belt of the lifting and polishing apparatus is slower than the speed of the pachinko balls that flow into the ball insertion opening of the lifting and polishing apparatus, the pachinko balls are carried upwards in close contact. The pachinko balls in the close-up state are in contact with each other and rub against each other in the opposite direction to act as a brake, thus acting as a load on the lifting belt. If the number of balls is small and the lifting force exceeds the brake, the lifting belt will not stop. However, when a certain limit is exceeded, the brake will win and a problem will occur that causes the lifting belt to stop. Such a problem is considered to occur not only in the lift polishing apparatus but also in other transport polishing apparatuses.
[0006]
In view of the above-described problems, the present invention can be applied not only to the lift polishing apparatus but also to other transport polishing apparatuses, regardless of the speed of the transport belt. It is an object of the present invention to provide a ball feeding amount suppressing device for a novel conveying and polishing apparatus capable of conveying a pachinko ball while polishing without biting the pachinko ball by preventing the pachinko ball from being conveyed in close contact.

(Schematic structure of pachinko ball lifting and polishing equipment)
A schematic configuration of a pachinko ball lifting and polishing apparatus 1 (hereinafter simply referred to as “lifting and polishing apparatus 1”), which is an application example of a guide member to be described later, will be described with reference to FIGS. The lift polishing apparatus 1 is generally composed of a base portion 3 installed on the floor and a lift tower 5 standing up from the base portion. A door portion 7 (see FIG. 2) is hinged to the front of the lifting tower 5 so as to be opened and closed. Inside the lifting tower 5, a guide member 11 and a polishing cloth 13 used as an abrasive are installed so that the lifting belt 15 can pass therethrough. Reference numeral 17 shown in FIG. 3 indicates a guide roller for guiding the feeding belt 15. A plurality of guide rollers 17 are provided at predetermined intervals in the length direction of the feeding belt 15. The detailed structure of each member will be described below.
[0020]
(Structure of the lifting belt)
As shown in FIGS. 1 and 2, the feeding belt 15 is an endless belt stretched by a driving roller 21 and a driven roller 23, and is rotated with a motor 25 as a driving source. Further, it passes through the lifting tower 5 on the outward path viewed from the drive roller 21 and passes through the belt cover 27 on the return path. The lifting belt 15 has a conveyance surface 15a (see FIG. 3) that contacts a pachinko ball to be conveyed, and has sufficient elasticity to apply a pressing force to the pachinko ball. The material constituting the lifting belt 15 is generally synthetic rubber, but may be a material other than synthetic rubber (for example, cloth material, synthetic leather material) or a composite thereof.
[0021]
(Guide member structure)
The guide member 11 shown in FIG. 3 is made of a material that can apply a sufficient pressing force to the pachinko balls to be transported together with the lifting belt 15. There is a synthetic resin material with hardness. More specifically, there are simple substances and composites such as artificial marble and epoxy resin based on acrylic resin. As shown in FIG. 3, the guide member 11 has a guide surface 11 a that faces the conveyance surface 15 a of the lifting belt 15. The guide member 11 is constituted by a wide guide constituent member having a plurality of polishing guide grooves 31 described later, or by connecting a plurality of guide constituent pieces arranged in parallel by a connecting means such as a screw member. is there.
[0022]
On the guide surface 11 a side of the guide member 11, a polishing guide groove 31 extending along the pachinko ball conveying direction is formed. The polishing guide groove 31 constitutes a guide groove as a pachinko ball conveyance path. The shape of the polishing guide groove 31 is formed in a groove shape in which the pachinko ball contacts the groove bottom 31a (see FIG. 7) at one point, and is not different from a guide groove as a normal pachinko ball conveyance path. . The cross-sectional shape of the polishing guide groove 31 is formed so that a pachinko ball can be partially received via a polishing cloth 13 to be described later. Since the number of strips of the polishing guide groove 31 is set in accordance with circumstances such as the effective width of the guide member 11 and the number of pachinko balls being lifted, there is no problem in increasing or decreasing within the range permitted by the circumstances.
[0023]
(Abrasive cloth structure)
As long as the polishing cloth 13 shown in FIGS. 3 and 4 can be mounted on the guide surface 11a of the guide member 11 and can polish the pachinko balls, there is no limitation on the form or material. In the present embodiment, a strong cotton cloth is used as the polishing cloth, and it is configured to be detachable so that it can be easily replaced when it becomes dirty.
[0024]
(Structure of round guide member of pachinko ball inflow part)
Next, the rounded guide member 41 constituting the pachinko ball inflow portion of the lifting and polishing apparatus 1 will be described with reference to FIGS. 4 and 5. When the lifting belt 15 driven by the drive roller 21 and the driven roller 23 (not shown) moves to the lower end, the rounded guide member 41 sandwiches pachinko balls between the lifting belt 15 and the conveying direction. It is a member for guiding to. The rounded guide member 41 includes a rounded bottom plate 43 and an upper end base 45 connected to the lower end of the guide member 11. One rounded guide groove 46 is formed on the rounded guide member 41 on the side of the feeding belt 15. The round-shaped guide groove 46 constitutes a guide groove as a pachinko ball conveyance path, and the pachinko ball is provided with respect to each polishing guide groove 31 of the guide member 11 located downstream of the pachinko ball conveyance path. It is formed so that balls can be guided in a single column. Details of the shape and the like of the rounded guide groove 46 will be described later. The rounded guide member 41 is made of the same synthetic resin as that of the guide member 11 and conveys the received pachinko ball while being pressed by the pressing force of the lower end of the lifting belt 15. That is, the inserted pachinko balls are guided in the direction of the linear guide member 11 while being sandwiched between the lifting belt 15 wound around the drive roller 21 and the rounded guide member 41.
[0025]
In addition, when the rounded guide member 41 is configured to be divided into a plurality of members and the rounded guide portion receives a pressing force, the individually rounded guide portions are separated from other rounded guide portions. Independently, for example, it may be configured to be elastically deformable by a coil spring or the like. If configured so as to be elastically deformable in this way, even if a partial imbalance occurs in the pressing force received by each R-shaped guide portion from the feeding belt 15, the R-shaped guide portions that have received the pressing force independently Since it corresponds to the pressing force, the unbalance does not adversely affect the entire rounded guide member 41. In this case, the coil spring may be omitted when the elastic restoring force of each rounded guide portion itself is sufficient.
[0026]
The pachinko balls guided by the rounded guide member 41 and the lifting belt 15 are received in the polishing guide groove 31 of the guide member 11 via the abrasive 13 and are lifted and polished by the pressing force of the lifting belt 15. . The polishing material 13 is inserted into the polishing guide groove 31 from the polishing cloth introduction port 14 formed at the connection portion between the terminal end of the rounded guide member 41 and the lower end of the guide member 11, and a pachinko ball that moves upward by lifting is provided. The guide member 11 is stretched so as to be polished, and is configured to be pulled out of the polishing guide groove 31 from the upper end of the guide member 11. The new polishing surface of the polishing material 13 is pulled out from the polishing cloth inlet 14 at the lower end of the guide member 11 into the polishing guide groove 31 by lowering the polishing material 13 drawn from the upper end of the guide member 11. It is comprised as follows.
[0027]
(Structure of the ball pinching amount suppression part of the pachinko ball inflow part)
With reference to FIGS. 4 and 5, the structure of the ball pinching amount suppressing portion of the pachinko ball inflow portion will be described. In the present embodiment, the structure of the indentation amount suppressing portion has one feature. As shown in FIG. 4, the ball-shaped guide member 41 constituting the pachinko ball inflow portion is provided with a ball insertion slot 42. The ball insertion port 42 is a pachinko ball insertion port for conveying a large amount of pachinko balls discharged and collected from a pachinko machine (not shown) to the lifting and polishing apparatus 1. In the ball slot 42, the entrance is formed with a slightly receding downward slope so that the pachinko balls can easily flow into the rounded guide groove 46. After the pachinko balls flow into the rounded guide grooves 46, the pachinko balls are rolled and conveyed in a state of being sandwiched between the lifting belts 15 by the guide grooves formed in a single row, It is conveyed to the guide member 11 connected to the rounded guide member 41.
[0028]
As shown in FIG. 4, the ball penetration amount suppressing portion of the present embodiment is formed in a section extending from the ball insertion port 42 of the rounded guide member 41 to the introduction portion of the guide member 11. In addition, this ball penetration amount suppression part may be formed in the area from the ball penetration port 42 to the terminal end of the upper end base 45 of the rounded guide member 41.
[0029]
Next, a specific structure of the guide groove of the pachinko ball constituting the ball insertion amount suppressing portion will be described. As shown in FIG. 6, the guide groove that constitutes the ball insertion amount suppressing portion includes a round guide groove 46 of the round guide member 41 and an introduction guide groove 36 of the introduction portion of the guide member 11. Alternatively, as described above, it may be constituted solely by the rounded guide groove 46 of the rounded guide member 41. The cross-sectional shapes of the rounded guide groove 46 and the introduction guide groove 36 are formed in a mode in which the opening of the groove surface is gently widened so that the pachinko balls can be easily received. 46) is substantially semi-circular and has a diameter slightly smaller than the diameter of the pachinko ball. For this reason, the pachinko ball is formed so as to be in contact with the upper portion of the groove main body portion in the rounded guide groove 46 and the introduction guide groove 36, and the bottom portion of the groove main body portion is configured not to contact the pachinko ball. Has been. Accordingly, in the portion of the rounded guide member 41 extending from the ball insertion port 42 to the upper end base 45, the pachinko ball contacts at two points between the two side surfaces of the upper portion of the groove body portion of the rounded guide groove 46. Then, it is conveyed by the lifting belt 15 while being supported in a suspended state. Subsequently, the pachinko balls are conveyed in a suspended state in a two-point contact to the introduction guide groove 36 that spans the introduction portion of the guide member 11 connected to the rounded guide groove 46, and further the polishing guide groove 31 on the downstream side. It is to be transported to. It should be noted that the shape of the groove main body portion of the rounded guide groove 46 and the introduction guide groove 36 is not formed to be smaller in diameter than the pachinko ball, but has a sub-groove whose bottom does not contact the pachinko ball. It may be formed. The point is that the pachinko ball is supported in a suspended state by two-point contact between the two side surfaces of the upper portion of the groove main body portion of the round guide groove 46 and the introduction guide groove 36 as described above. It is good.
[0030]
Thus, when the suspended pachinko ball supported at two points between the two side surfaces of the groove main body is conveyed while being guided by the lifting belt 15 to the rounded guide groove 46 and the introduction guide groove 36, The speed of transfer (center trajectory) due to rolling of the pachinko ball itself is relatively slow with respect to the speed of the lifting belt 15. In other words, rather than the speed of the pachinko ball itself when it is conveyed while being rolled in contact with the bottom of the groove body, the transfer speed due to rolling of the pachinko ball in the suspended state as described above is The rolling contact radius of the pachinko ball is slower than the radius of contact with the pachinko ball lifting belt 15.
[0031]
Therefore, as described above, in the ball insertion amount suppressing portion of the present embodiment, the pachinko balls are supported in a suspended state between the two side surfaces of the upper portion of the groove main body portion in the rounded guide groove 46 and the introduction guide groove 36. It is comprised by the structure which has such a form.
[0032]
On the other hand, as shown in FIG. 7, the shape of the polishing guide groove 31 of the guide member 11 is a shape that is the same as that of a normal shape formed with a slightly larger diameter than the pachinko ball. For this reason, the guide member 11 is configured such that the pachinko balls are conveyed by the lifting belt 15 in contact with the groove bottom portion 31a of the polishing guide groove 31 in a one-point contact state.
[0033]
(Basic concept of onion control part)
As explained above, the basic concept of the ball penetration control part for the pachinko balls is that the driving speed of the belt by the lifting belt is a constant speed, and the grinding is carried out from the ball insertion opening of the pachinko balls. Until the process start section, the speed of the pachinko balls transferred by the lifting belt is set to be relatively slower than the speed in the lifting polishing process, and from the lifting polishing process after passing this section, It is to make a space between the pachinko balls being transported by speeding up the transport speed. This is to prevent the biting of the ball while the pachinko ball is being conveyed. That is, as shown in FIG. 8, the movement distance of the center Pa of the pachinko ball P per one rotation between the outer peripheral point P1 when the pachinko ball P is in contact with one point and the point P2 when the pachinko ball P is in contact with two points. L is the movement distance L1 of the pachinko ball P having the contact radius (R) when the contact distance L2 in the case of two-point contact is smaller than the apparent contact radius (r) as shown in the figure. Smaller than. That is, the movement distance per rotation in the case of one point contact is longer than that in the case of two point contact. Therefore, in the transfer by the lifting belt 15 at the same speed, when the pachinko ball P is transferred from the two-point contact transfer state in which the pachinko balls P are transferred in a close contact state, Due to increased transport speed due to longer travel distance The pachinko ball P and the pachinko ball P are transported in an open state.
[0034]
(Effect of onion control part)
Next, the effect | action of the ball penetration amount suppression part which conveys the pachinko ball with the raising belt 15 is demonstrated. In FIG. 9, the passing state of the pachinko balls in the transport passage of the pachinko balls transported by the lifting belt 15 is shown for the ball entrainment amount suppressing portion and the subsequent lifting and polishing steps. FIG. 9 is a plan view of a guide groove with respect to a pachinko ball in which the rounded guide member 41 and the guide member 11 are continuously connected when the pachinko ball P is viewed from the lifting belt 15 side. Is shown. In the lower part of the figure, from the groove shape described above, the ball insertion amount suppressing part has a rounded guide groove 46 for supporting the pachinko ball P in a suspended state in two-point contact and a side surface of the groove main body part of the introduction guide groove 36. The pachinko ball travel trajectory T2 is two, and in the feeding and polishing process after the ball indentation amount suppressing portion, the pachinko ball travel trajectory T1 in the groove bottom portion 31a of the polishing guide groove 31 that supports the pachinko ball P in a single contact state. Is represented as Article 1. As described above, in the ball jamming amount restraining portion, the pachinko ball travel locus is in the two-row portion and the one-row portion, even if the lifting belt 15 is at the same speed, the moving speed of the pachinko ball itself is higher than that in the two-row portion. The first section is also faster. Therefore, in the ball jamming amount suppressing portion in the illustrated two-row portion, the pachinko ball P is conveyed in a close contact state with a slow moving speed even if the lifting belt 15 is at the same speed, but in the single-row portion, the moving speed is low. Therefore, the sheet is transported with an interval as shown in the figure.
[0035]
Conveyed by the lifting belt 15 in the conveyance path after flowing into the ball insertion opening 42 of the lifting and polishing apparatus 1 and passing through the ball loading suppression unit by the ball rolling amount suppression unit of the present embodiment. As shown in FIG. 10, the pachinko balls P and the pachinko balls P are spaced apart from each other regardless of whether the speed of the lifting belt 15 of the lifting and polishing apparatus 1 is fast or slow. It will be carried upwards. For this reason, in the lifting and polishing step shown in the upper part of FIG. 10, the contact state (lower part of FIG. 10) in the ball pinching amount suppression part of the pachinko balls P is eliminated and the separated state is conveyed. It will be. Therefore, there is no contact between the pachinko balls, the above-mentioned factor that becomes a brake is eliminated, and the danger that the lifting belt is restrained and stopped by the biting of the ball can be surely avoided.
[0036]
As a modified example of the present embodiment, the structure of the guide groove of the ball crushing amount suppressing portion can be applied to another conveyance polishing apparatus instead of the lift polishing apparatus 1. As such a transfer polishing apparatus, unlike the arrangement form of the vertically arranged lift polishing apparatus 1, it is possible to transfer the pachinko balls by arranging the lift polishing apparatus 1 in a horizontal direction or an oblique direction. The one configured in the above is conceivable. In this case, the conveying polishing apparatus applies various two-point contact guide grooves and one-point contact guide grooves that form the conveying path of the pachinko balls of the lifting and polishing apparatus 1 described above, thereby variously conveying the pachinko balls. It can be used for polishing while being transported by being installed in place of the replenishment jars and assembly bunches installed in Pachinko Island.
[0037]
【The invention's effect】
The present invention has the following effects.
1. According to the present invention, in the guide groove forming the pachinko ball conveyance path of the pachinko ball conveyance polishing apparatus, one guide groove of the guide grooves has a cross-sectional shape as a guide groove that is in two-point contact with the pachinko ball, and the amount of balls inserted Provided in the restraining portion, the other guide groove is continuously connected to the downstream side of the ball penetration amount restraining portion, and after passing through the ball penetration amount restraining portion having this two-point contact guide groove, the pachinko ball and 1 Since it is connected continuously to a guide groove with a normal cross-sectional shape that makes point contact, it can be transported with a distance that prevents the pachinko balls and pachinko balls from contacting each other by the transport belt, thus preventing the occurrence of ball biting. The trouble that the conveying belt of the pachinko ball conveying / polishing apparatus causes a ball engagement and becomes in a restrained state can be prevented.
2. In addition to the above, since the conveyance polishing apparatus itself has a ball crushing amount suppression unit, it is possible to automatically determine the amount of ball inflow into the conveyance polishing apparatus and suppress the pachinko ball conveyance amount. It is possible to reliably prevent the biting of the ball during the conveyance.
3. In addition to the above, the shape of the guide groove of the ball entrainment amount restraining part has a ball pressure receiving part with two-point contact, so that even if the pinching pressure of the pachinko ball is increased by the conveyor belt, the surface pressure of the ball pressure receiving part is increased. Can be lowered. From this, it is possible to realize a conveyance polishing apparatus that avoids a stop trouble due to the biting of the conveyance polishing apparatus and maintains the maximum conveyance amount of the conveyance polishing apparatus.
4). In addition to the above, it is not necessary to excessively increase the speed of the conveyor belt, and the minimum necessary electric motor and operation speed can be obtained. Therefore, energy saving, longer life of the mechanism unit, and noise reduction can be achieved.
5. In addition to the above, since the function of suppressing the amount of indentation can be realized only by the difference in groove cross-sectional shape, it is not necessary to have extra parts and mechanism parts, and space is saved.
6). Furthermore, since the interval between the pachinko balls to be conveyed and the pachinko balls can be set to a desired interval by appropriately adjusting the two-point contact groove shape of the guide groove of the ball insertion amount suppressing portion, the pachinko balls The carry amount can be adjusted.
