  With reference to FIGS. 3 to 13, the structures of the main pumping unit 110 and the upper pumping unit 130 will be described. In the present embodiment, the two front and rear main pumping sections 110 and the upper pumping section 130 having the same configuration are arranged with a predetermined width apart in the front-rear direction. In addition, although the main pumping part 110 and the upper pumping part 130 are each installed before and behind, since both the main pumping part 110 and both the upper pumping parts 130 are comprised in substantially the same way, in the following, Will describe one main lifting section 110 and both upper lifting sections 130.

  The main lifting unit 110 includes a plurality of (for example, five) paper pipes 111 and includes a paper pipe case 119 that stores these paper pipes 111 (see FIG. 11). The paper pipe 111 is a cylindrical member having an inner diameter slightly larger than that of the game ball 11. The paper pipe case 119 has a substantially U shape in a cross-sectional plan view and extends over the entire length of the paper pipe 111. In addition, a central support member 160 having a substantially U shape in a cross-sectional plan view is provided at the center position in the longitudinal direction of the main lifting part 110 (see FIGS. 3 and 8).

  As shown in FIGS. 8 and 12, the central support member 160 serves as an openable / closable stopper for holding the paper pipe 111 bundled by the pipe joint 112 inside the paper pipe case 119. The central support member 160 is formed with an engagement notch 160a that is engaged with an engagement projection 119e provided on the front and rear surfaces of the paper pipe case 119.

  As shown in FIG. 3, although a detailed description is omitted, the lower end of the main pumping unit 110 is connected to the lower pumping unit 301 by a known connecting member using a screw or the like. The lower end of the main pumping unit 110 and the upper end of the lower pumping unit 301 are relatively immovably connected and fixed by the lower pumping unit 301 so that the standing state of the main pumping unit 110 can be maintained. ing.

  As shown in FIGS. 4, 6, and 11, the pipe joint 112 provided at the upper end of the main lifting part 110 is made of a synthetic resin material or the like having a substantially rectangular parallelepiped shape and has a plurality of through holes 140 penetrating in the vertical direction. Are formed in parallel. Each through-hole 140 has a circular shape in a cross-sectional plan view, and has an inner diameter that is substantially the same as the inner diameter of the paper pipe 111, and a larger diameter portion 140b that has an inner diameter slightly larger than the outer diameter of the paper pipe 111. The upper end of the paper pipe 111 is inserted into the large diameter portion 140b, and the small diameter portion 140a restricts the paper pipe 111 from moving in the axial direction (upward) relative to the pipe joint 112. The pipe joint 112 itself is held so as to be movable relative to the paper pipe case 119. As described above, the upper ends of the plurality of paper pipes 111 (for example, five) are inserted into the through holes 140 of the pipe joint 112, so that the plurality of paper pipes 111 are integrated in a state of being bundled side by side. A unit 150 is formed.

  Although a detailed description is omitted, a member similar to the upper pipe joint 112 is also provided at the lower end of the main transporting portion 110 so that the paper pipe 111 is relatively relative to the lower pipe joint. Movement in the axial direction (downward) is restricted. The lower pipe joint itself is held so as not to move relative to the paper pipe case 119. That is, in the present embodiment, the lower end of the paper pipe case 119 is fixed, but the upper end of the paper pipe case 119 is movable, and the longitudinal direction of the paper pipe 111 is affected by the influence of temperature and humidity. When the size of the pipe pipe 112 is extended or shrunk, the upper pipe joint 112 is moved relative to the paper pipe case 119 so that it can cope with a change in the length of the paper pipe 111 in the longitudinal direction. Yes.

  Further, as shown in FIG. 11B, the inner diameter (eg, about 13.5 mm) of the large-diameter portion 140b is slightly longer than the outer diameter (eg, about 13 mm) of the paper pipe 111. The paper pipe 111 is inserted with play in the large diameter portion 140b. That is, the paper pipe 111 is disposed with a gap S1 with respect to the inner surface of the large-diameter portion 140b.

  In the present embodiment, the inner diameter (for example, about 13.5 mm) of the large diameter portion 140b is slightly longer than the outer diameter (for example, about 13 mm) of the paper pipe 111. It may be the same size as the outer diameter. The gap S1 is preferably of a size that does not affect the game ball 11 when it is moved from the upper end of the paper pipe 111 to the small diameter portion 140a. Further, for example, the inner surface of the end portion of the paper pipe 111 may be chamfered to form a tapered surface or the like so that the stepped portion is not formed.

  As shown in FIG. 11, the paper pipe case 119 includes a substrate 119a made of a metal plate or a synthetic resin plate or the like extending in the vertical direction, and a pair of side plates 119b and 119c bent from both sides of the substrate 119a. It is formed in a substantially U-shaped cross section and can accommodate a plurality of paper pipes 111 therein. In addition, in the vicinity of the upper ends of the side plates 119b and 119c, a metal connection plate 113 having a horizontally long rectangular shape is attached by a connection method such as welding.

  When the connection plate 113 is attached to the paper pipe case 119, a holding space portion having a square cylindrical shape in plan view is formed at the upper end portion of the paper pipe case 119 by the substrate 119a, the side plates 119b and 119c, and the connection plate 113. The pipe joint 112 is held by this holding space.

  The short side and the long side of the pipe joint 112 are slightly smaller than the short side and the long side of the holding space formed by the substrate 119a, the side plates 119b and 119c, and the connection plate 113. Then, the pipe joint 112 is inserted with play. That is, the pipe joint 112 is disposed with a gap S2 from the substrate 119a, the side plates 119b and 119c, and the connection plate 113 (see FIG. 11B).

  As shown in FIGS. 4 and 5, the upper lifting unit 130 is provided with five prism pipes 131 corresponding to the five paper pipes 111 of the main lifting unit 110. The prismatic pipe 131 has a rectangular shape in a sectional view, and a passage 131a through which the game ball 11 can pass is formed therein. The internal dimension of the passage 131a is formed to be slightly larger than the diameter of the game ball 11 so that the game balls 11 can pass one by one. The five prism pipes 131 are connected to each other by welding or the like.

  As shown in FIG. 5, the lower end of the upper pumping unit 130 holds the lower end of the prismatic pipe 131 in a state in which five prismatic pipes 131 are arranged in parallel, and is slidable to the upper end of the main pumping unit 110. A slide connection part 132 to be connected is provided. The slide connecting portion 132 is a box in which two metal plates are bent in a substantially U shape in plan view, and the metal plates are screwed together via protruding pieces 135 formed on the side surfaces (front and rear surfaces). It is a shaped member.

  In addition, a movable connecting portion 120 that holds the slide connecting portion 132 of the upper lifting portion 130 in a slidable state is provided at the upper end of the main lifting portion 110. The movable connecting portion 120 is formed with a holding piece 117 in which a part of the paper pipe case 119 is extended, and the holding piece 117 can be held so as to surround the slide connecting portion 132 (see FIG. 4). The slide connecting portion 132 is inserted into the movable connecting portion 120 from above, and the lower end surface of the slide connecting portion 132 is brought into contact with the upper end surface of the pipe joint 112 at the upper portion of the main lifting section 110. A feed path that communicates between the paper pipe 111 and the prismatic pipe 131 of the main feed section 110 is configured. Further, the movable connecting portion 120 is formed with a guide groove 118 into which the projecting piece 135 of the slide connecting portion 132 is inserted from above to guide the slide connecting portion 132.

  A catch clip 133 is provided on one side surface of the slide connecting portion 132 of the upper lifting portion 130. Further, the connection plate 113 on the upper part of the main lifting part 110 is provided with a hooking piece 114 on which the catch clip 133 is hooked. Furthermore, the catch clip 133 has a latching rod 136 provided via two coiled springs 134, and a predetermined operation can be performed in a state where the latching rod 136 is latched on the latching piece 114. By doing so, the hooking rod 136 is hooked on the hooking piece 114 in a state where the urging force of the spring 134 is applied. That is, the slide connecting portion 132 at the lower end of the upper lifting portion 130 is held in a state of being pressed toward the pipe joint 112 at the upper portion of the main lifting portion 110 by the urging force of the spring 134.

  As shown in FIG. 7 (A), the catch clip 133 is provided with an urging means such as a spring 134, so that the upper lifting part 130 and the main lifting part 110 are connected to each other, Within the expansion / contraction range of the spring 134, the relative movement of the upper lifting part 130 and the main lifting part 110 is possible. Therefore, as shown in FIG. 7B, when the length of the paper pipe 111 in the main feed section 110 is increased due to the influence of temperature and humidity, the upper pipe joint 112 is moved upward. The feeding unit 130 can be moved in the direction of pushing up, and can cope with a change in the dimension of the paper pipe 111 in the longitudinal direction. Further, even when the longitudinal dimension of the paper pipe 111 is reduced, the upper feed unit 130 is lowered as the upper pipe joint 112 is lowered.

  Further, the slide connecting portion 132 is arranged at a normal position such that the protruding piece 135 is arranged above the lower end side of the guide groove 118 by a predetermined distance so that the protruding piece 135 does not contact the lower end side of the guide groove 118 (see FIG. 7 (A) and the intermediate position of FIG. 7 (B), the downward movement of the slide connecting portion 132 is allowed.

  Note that when the protruding piece 135 of the slide connecting portion 132 is brought into contact with the lower end of the guide groove 118, the downward movement of the slide connecting portion 132 is restricted. For this reason, the slide connecting portion 132 is prevented from moving downward beyond an assumed range, and a load is not applied to the paper pipe 111.

  Note that the upper end of the upper pumping unit 130 is held in an insertion hole 77 provided in the upper tank 70 so as to be movable in the vertical direction. For example, when the paper pipe 111 expands or contracts beyond the expansion / contraction range of the spring 134, the upper end of the paper pipe 111 moves together with the upper lifting unit 130 that is held in the upper tank 70 so as to be movable in the vertical direction. You may do it.

  As described above, in the present embodiment, the lower lifting unit 301, the main lifting unit 110, and the upper lifting unit 130 are connected to the discharge port of the main body of the lifting apparatus 100 at the lower end of the lower lifting unit 301, The main pumping unit 110 is connected to the upper end of the feeding unit 301, the upper pumping unit 130 is connected to the upper end of the main pumping unit 110, and the upper end of the upper pumping unit 130 is inserted into the upper tank 70. As a result, a pumping path that is connected in series in the vertical direction and integrated is formed between the pumping device 100 and the upper tank 70.

  Here, the pipe joint 112 of the pipe unit 150 is disposed with a gap S2 from the substrate 119a, the side plates 119b and 119c, and the connection plate 113 (see FIG. 11B), so that the paper pipe case 119 and The pipe unit 150 is supported by the paper pipe case 119 and the connection plate 113 so that they can vibrate because they are supported in the cylindrical support portion made of the connection plate 113 so as to be movable in the horizontal direction by the gap S2.

  A convex portion extending in the vertical direction is formed on one connection surface of the pipe joint 112, and a concave portion or the like extending in the vertical direction is formed on the other connection surface. When the pipe joint 112 is connected, the convex portion is formed in the concave portion. By fitting, the displacement in the horizontal direction may be regulated while allowing the movement in the vertical direction, and in this way, the small diameter of the connected pipe joint 112 is controlled. Since the axial center of the part 140a is not displaced, it is possible to suppress the formation of a step or the like and clogging of the balls.

  In addition, a substantially central portion in the longitudinal direction of the main lifting unit 110 is supported by a paper pipe case 119 and a central support member 160 as shown in FIG. Each paper pipe 111 is disposed with a gap between the paper pipe case 119 and the central support member 160, and when the paper pipe 111 is not bent or vibrated by the movement of the game ball 11, Although it does not contact the pipe case 119, it is supported by contacting the central support member 160 and the paper pipe case 119 only when the paper pipe 111 is bent or moved in the horizontal direction.

  As shown in FIG. 13, in the present embodiment, when a lifting force is applied by the lifting device 100, the game ball 11 waiting in a daisy chain state is pushed upward in the paper pipe 111 and lifted. It has come to be. Since the inner diameter L10 (about 12 mm) of the paper pipe 111 is slightly larger than the diameter 2R (about 11 mm) of the game ball 11 (L10> 2R), it can move in a direction orthogonal to the axis of the paper pipe 111. In addition, since the ball pressure from the upper game ball 11 is applied to the lower game ball 11, the game balls 11 are stacked with the center point P0 shifted in the horizontal direction. Therefore, when a lifting force is applied by the lifting device 100, each game ball 11 moves upward while sliding on the inner surface of the paper pipe 111, and a rotational force is applied by the sliding contact to move the upper and lower sides. The game balls 11 also move so as to slidably contact each other or circulate along the inner surface of the paper pipe 111. That is, when the game ball 11 moves upward in the paper pipe 111, vibration occurs due to the game ball 11 circling or slidingly contacting the inner surface of the paper pipe 111.

  Further, in this embodiment, since paperboard is used as the material of the pipe of the main lifting unit 110, the paper pipe 111 has appropriate flexibility. For this reason, as shown in FIG. 4, the paper pipe 111 is not supported entirely by the supporting means, but only the upper and lower ends are only partially supported by the pipe joint 112. The other flexible portion can be bent by the movement of the game ball 11 being lifted.

  Thus, in the pipe unit 150, the paper pipe 111 is inserted into the large diameter portion 140b with play. In addition, the pipe joints 112 at the upper and lower end portions are supported so as to be able to vibrate by being disposed with a gap S2 with respect to the paper pipe case 119 and the connection plate 113 (see FIG. 11B), and in the longitudinal direction. The substantially central portion is supported by the paper pipe case 119 and the central support member 160 so as to be able to vibrate by being arranged with a gap with respect to the support means in the central portion formed in a square tube shape. Therefore, each of the paper pipes 111 vibrates with respect to the paper pipe case 119, the connection plate 113, and the central support member 160 due to the movement of the game balls 11 in the paper pipe 111 moving upward. Contact and contact between the inner surface of the paper pipe 111 and the game ball 11 are promoted.

  The plurality of paper pipes 111 have appropriate flexibility, and upper and lower ends integrated by a pipe joint 112 are supported by a paper pipe case 119 and a connection plate 113, and a substantially central portion in the vertical direction is formed. It is only supported by the central support member 160, and is not supported as a whole. That is, the plurality of paper pipes 111 have supported support portions (upper and lower end portions and a substantially central portion) and unsupported flexible portions (parts other than the upper and lower end portions and the substantially central portion). As a result, the flexible ball that is not integrated by the pipe joint 112 is bent by the movement of the game ball 11 in the paper pipe 111 moving upward, so that the contact between the game balls 11 and the paper pipe 111. The contact between the inner surface and the game ball 11 is promoted.

  When the paper pipe 111 is slightly expanded or contracted due to changes in temperature or humidity, the flexible portion that is not integrated by the pipe joint 112 bends to allow the expansion and contraction of the paper pipe 111.

  In this embodiment, the pipe joint 112 is formed with a plurality of through-holes 140 penetrating in the vertical direction so that the paper pipes 111 are spaced apart from each other. Adjacent paper pipes 111 may be brought into contact with each other by communicating and integrating a plurality of through holes 140 formed in 112. By doing so, the vibration of one of the plurality of paper pipes 111 can be easily transmitted to the other paper pipes 111, so that the polishing effect of each paper pipe 111 can be improved.

  Further, at least one paper pipe 111 of the plurality of paper pipes 111 is brought into contact with or close to another paper pipe 111 (for example, a state in which the separation width is about 1 to 3 mm). Since the vibration of the paper pipe 111 is easily transmitted to the other paper pipes 111, the polishing effect of each paper pipe 111 can be improved.

  Next, dirt that adheres to the game ball 11 will be described. Table 1 is a table showing dirt components adhering to a paper pipe (polishing pipe) and a basket through which the game ball 11 passes. Table 2 is a table showing the components of dirt when the moisture is removed from the dirt that adheres to the paper pipe and the basket through which the game ball 11 passes. The dirt adhering to the paper pipe and the bag is a transfer of the dirt adhering to the game ball 11. The foreign matter A, the foreign matter B, and the foreign matter C are different stains at different locations.

  Referring to Tables 1 and 2, the oil content is derived from mineral oil applied to each part through which the game ball 11 passes and sebum such as a player and a game shop clerk. The water-insoluble substance is derived from fiber components such as clothes of players and game shop clerk and cleaning tools. C, O, and Na are derived from sodium lactate, which is a component contained in sweat, such as a player and a game shop clerk, and a lactate salt brought into the game hall together with them. Mg, Al, Si, S, Cl, K, Ca, Cr, Ni, and Cu are components contained in sweat, such as players and shop assistants, and salts other than lactate that are brought into the game hall together with them. Derived from.

  Based on the data in Table 2, the components derived from sodium lactate in the foreign matter A, foreign matter B, and foreign matter C from which moisture was removed were 35.3%, 39.9%, and 42.2%, respectively. It occupies a high rate of around 40%. For this reason, if sodium lactate can be removed effectively, most of the dirt adhering to the game ball 11 can be removed effectively.

  Here, lactate such as sodium lactate sticks firmly to an attached object (for example, game ball 11) when moisture is removed. In the pipe-type polishing apparatus, if the material of the polishing member used for the inner surface of the pipe is not specified, moisture is removed from the dirt components adhering to the game ball 11, and as a result, it adheres to the game ball 11. It makes it difficult to remove lactate from dirt. Therefore, in order to remove the dirt, it is important to leave moisture appropriately or supply moisture appropriately.

  In this embodiment, it is possible to supply moisture to the surface of the game ball 11 immediately before entering the paper pipe 111 by connecting a humidifier 600 (see FIG. 2) described later to the lifting device 100. ing.

  In this embodiment, cardboard is used as the material of the paper pipe 111. The reason for this is as follows. The cardboard has moderate flexibility. For this reason, as shown in FIG. 4, the plurality of paper pipes 111 are not integrated by the pipe joint 112 by providing a portion where the plurality of paper pipes 111 are integrated by the pipe joint 112 and a portion which is not integrated. The flexible part of the paper pipe 111 is bent by the movement of the game ball 11 being lifted. This bending promotes the contact between the game balls 11 and the contact between the game ball 11 and the biodegradable material layer on the inner surface of the paper pipe 111, and also promotes the change (biodegradation) of the contacting portion. As a result, removal of the game balls 11 can be promoted and the polishing effect can be improved.

However, if only the paper pipe 111 is used for the main lifting part 110, the water vapor permeability becomes high, and moisture adhering to the game ball 11 flowing through the inside is diffused to the outside of the paper pipe 111. End up. For this reason, sticking of lactate to the game ball 11 is further promoted. In order to solve such a problem, in this embodiment, a biodegradable material layer having a relatively low water vapor transmission rate is used as the polishing member on the inner surface of the paper pipe 111 of the main pumping unit 110. Here, the biodegradable material layer preferably has a water vapor permeability of 1000 g / m ² · 24 h or less at 40 ± 0.5 ° C. and 90 ± 2% RH.

  FIG. 9 is a diagram illustrating the structure of the paper pipe 111 of the main lifting unit 110 according to the first embodiment. Referring to FIGS. 9A and 9B, a paper pipe 111 includes a cylindrical body 1112 serving as a base of the paper pipe 111 and a biodegradable material layer 1111 formed inside the cylindrical body 1112. Have. A game ball 11 flows inside the paper pipe 111.

  Here, the biodegradable material layer 1111 is preferably a polyester-based decomposable resin, a natural polysaccharide, or an animal or vegetable resin, alone or a mixture of a plurality thereof. According to this, the biodegradable material layer 1111 is biodegraded so that the inner surface of the paper pipe 111 is gradually roughened over time. Can be adsorbed, so that the game ball 11 can be more suitably polished inside the paper pipe 111.

  The game ball 11 has a diameter of 11 mm. The cylinder 1112 has a thickness of about 1 mm and an inner diameter L10 of about 12 mm. The biodegradable material layer 1111 is formed by spirally winding a strip (film) having a width of about 3 cm and a thickness of about 30 μm. Further, the edges of adjacent strips are overlapped. In this embodiment, the overlap width is 0.3 mm. The biodegradable material layer 1111 is attached to the inside of the cylinder 1112 with an adhesive.

  The dirt of the game ball 11 can be removed from the surface of the biodegradable material layer 1111 and the stepped portion where the strips overlap. The removed dirt accumulates in the stepped portion where the strips overlap. Further, the dirt of the game ball 11 can be further removed by the adsorbing power of the accumulated dirt. This is considered to be because the suction force between the dirts is stronger than the suction force between the game balls 11 and the dirt. Thereby, the dirt accumulated in the step portion can be removed from the game ball 11. Further, as described above, the biodegradable material layer 1111 is biodegraded so that the inner surface of the paper pipe 111 is gradually roughened over time, and a large amount of dirt is attached to restore the reduced adsorption force. Can be adsorbed.

  Note that the dimensions of each part may be other dimensions as long as the flow of the game ball 11 is not hindered. For example, when the inner diameter L10 of the cylindrical body 1112 is 11.5 mm and the thickness of the strip-shaped body is 50 μm, the inner diameter L10 of the paper pipe 111 is 11.5−50 / 1000 × 2 = 11 at the overlapping portion of the strip-shaped body. 4 mm. However, since the inner diameter of the paper pipe 111 in this case is larger than the diameter 11 mm of the game ball 11, the game ball 11 can flow.

As long as the strip of the biodegradable material layer 1111 has at least a water vapor permeability lower than that of the cylinder 1112, compared to the case where the biodegradable material layer 1111 is not present, the strip-like body of The amount can be reduced, and as described above, the water vapor permeability at 40 ± 0.5 ° C. and 90 ± 2% RH is preferably 1000 g / m ² · 24 h or less. According to this, since the water vapor permeability of the biodegradable material layer is less than a predetermined value, it is easy to leave moisture of dirt (for example, sodium lactate) adhering to the game ball 11, and as a result, it is easy to adsorb dirt. Can do.

  Also, if the inner surface of the biodegradable material layer 1111 has at least a kinetic friction coefficient and a static friction coefficient lower than those of the inner surface of the cylinder 1112, compared to the case where the biodegradable material layer 1111 does not exist on the inner surface of the cylinder 1112. Friction between the inner surface of the pipe 111 and the game ball 11 can be reduced. In general, a biodegradable material film has a lower coefficient of dynamic friction and a lower coefficient of static friction than paper such as cardboard of the cylinder 1112. As a result, the flow of the game ball 11 in the paper pipe 111 can be made smooth.

  The biodegradable material layer 1111 is fixed to the cylindrical body 1112 by attaching the film of the band-like body with an adhesive. The adhesive is preferably made of a biodegradable resin such as a polyester resin, a polylactic acid resin, a natural rubber resin, or polyvinyl alcohol. According to this, since the biodegradable material layer 1111 formed in a film shape is adhered to the inner surface of the cylindrical body 1112 with the adhesive made of biodegradable resin, the process of forming the biodegradable material layer on the inner surface of the paper pipe 111 Easy to do.

  In the first embodiment, the case where the edges of adjacent strips (films) of the biodegradable material layer 1111 of the paper pipe 111 are overlapped has been described. In the second embodiment, a case where there is a gap between adjacent strips of the biodegradable material layer 1111 of the paper pipe 111 will be described. The property of the biodegradable material layer 1111 is the same as that of the first embodiment.

  FIG. 10 is a diagram illustrating the structure of the paper pipe 111 of the main lifting unit 110 according to the second embodiment. Referring to FIGS. 10A and 10B, as in the first embodiment, the paper pipe 111 includes a cylindrical body 1112 that is a base of the paper pipe 111 and a raw material formed inside the cylindrical body. A decomposition material layer 1111. A game ball 11 flows inside the paper pipe 111.

  The cylinder 1112 has a thickness of about 1 mm and an inner diameter L10 of about 12 mm. The biodegradable material layer 1111 is formed by spirally winding a strip having a width of 3 cm and a thickness of 30 μm. In addition, a gap is made between adjacent strips. In the present embodiment, the width of the gap is 0.3 mm.

  The dirt of the game ball 11 can be removed on the surface of the biodegradable material layer 1111 and the gap portion of the belt-like body. The removed dirt accumulates in the gap portion of the belt-like body. Further, the dirt of the game ball 11 can be further removed by the adsorbing power of the accumulated dirt. This is considered to be because the suction force between the dirts is stronger than the suction force between the game balls 11 and the dirt. Thereby, the dirt accumulated in the gap portion can be peeled off from the game ball 11. Further, as described above, the biodegradable material layer 1111 is biodegraded so that the inner surface of the paper pipe 111 is gradually roughened over time, and a large amount of dirt is attached to restore the reduced adsorption force. Can be adsorbed.

  The properties of the biodegradable material layer 1111 described in the first and second embodiments are preferably as follows.

  First, the paper pipe 111 is preferably formed by forming a layer containing sodium lactate on the inner surface of the cylindrical body 1112. As shown in Tables 1 and 2, since the dirt adhering to the game ball 11 contains a large amount of sodium lactate, the layer formed on the inner surface of the cylinder 1112 contains sodium lactate as the dirt component. As a result, the affinity between the two becomes relatively good, and the dirt adhering to the game ball 11 can be easily adsorbed.

  Moreover, it is preferable that the said sodium lactate is a composition of the biodegradable material layer 1111 formed in a film form. According to this, since the biodegradable material layer 1111 is formed in a film shape, it is easy to process to form the biodegradable material layer 1111 on the inner surface of the paper pipe 111, and sodium lactate which is a dirt component is included in the composition of the film. Since it is a thing, affinity with the stain | pollution | contamination adhering to the game ball | bowl 11 becomes comparatively good, and can make it easy to adsorb | suck this stain | pollution | contamination.

  The sodium lactate may be contained in a coating agent applied to the film of the biodegradable material layer 1111. According to this, since the biodegradable material layer 1111 is formed in a film shape, it is easy to process the biodegradable material layer 1111 on the inner surface of the paper pipe 111, and sodium lactate which is a dirt component is applied to the film. Since it is contained in the applied coating agent, the affinity with the dirt adhering to the game ball 11 becomes relatively good, and the dirt can be easily adsorbed.

  The biodegradable material layer or the coating agent preferably contains 9.2 to 34.2% by weight, preferably 15.5 to 28.0% by weight of sodium lactate. This value is based on the value of sodium lactate (C, O, Na) contained in the foreign substances A to C shown in Table 1 (that is, the dirt that has adhered to the game ball 11 has moved to the paper pipe 111). It is determined so as to contain sodium lactate of a weight percent close to the composition of the components, and thereby the affinity between the biodegradable material layer or the coating agent and the dirt component becomes relatively good, so that it adheres to the game ball 11 Dirt can be easily absorbed.

  The biodegradable material layer or the coating agent preferably contains 7.8 to 20.0% by weight, preferably 12.0 to 18.0% by weight of oil in addition to sodium lactate. This value is based on the value of oil contained in the foreign matter A to C shown in Table 1 (that is, the dirt that has adhered to the game ball 11 has moved to the paper pipe 111). It is determined so as to contain oil, and thereby the affinity between the biodegradable material layer or coating agent and the dirt component becomes relatively good, so that the dirt attached to the game ball 11 can be easily adsorbed. .

  The oil contained in the biodegradable material layer or the coating agent is preferably mineral oil and / or sebum oil. This is because the oil contained in the foreign matter A to C shown in Table 1 (that is, the dirt attached to the game ball 11 has moved to the paper pipe 111) is mineral oil and / or sebum oil, Since the affinity between the biodegradable material layer or coating agent containing the mineral oil and / or sebum oil and the dirt component becomes relatively good, dirt attached to the game ball 11 can be easily adsorbed. Here, the mineral oil is, for example, machine oil or grease oil, and the breakdown of the fatty acid of the sebum oil is, for example, 4.4% lauric acid, 7.8% myristic acid, 12.0% palmitoleic acid, 22.7 palmitic acid. %, Oleic acid 17.2%, stearic acid 5.7%.

  Furthermore, the biodegradable material layer or the coating agent may contain a fiber component in addition to the sodium lactate. This is because the foreign substances A to C shown in Table 1 (that is, the dirt adhering to the game ball 11 moved to the paper pipe 111) contain a fiber component that is a water-insoluble substance, and thereby the biodegradable material layer Alternatively, the affinity between the coating agent and the dirt component is relatively improved, so that the dirt attached to the game ball 11 can be easily adsorbed.

  As described above, in the polishing apparatus according to the present embodiment, the lifting device 100 as a lifting means that receives the game ball 11 and applies a lifting force to the game ball 11, and the lifting device. A paper pipe 111 that is connected to 100 and that guides the game ball 11 that has been given the lifting force through the interior and guides the game ball 11 upward while supporting the paper pipe 111. A paper pipe case 119, a connection plate 113, and a central support member 160 are provided as means, and the support means supports at least a part of the paper pipe 111 so as to vibrate by the movement of the game ball 11 to which the paper pipe 111 is lifted. .

  For example, the paper pipe 111 is inserted into the large diameter portion 140b with play. Further, the pipe joints 112 at the upper and lower end portions are supported by the paper pipe case 119 and the connection plate 113 so as to be able to vibrate by being spaced apart from each other, and the substantially central portion in the longitudinal direction is supported by the paper pipe case 119. And the central support member 160 are supported so as to be able to vibrate by being arranged with a gap therebetween. That is, the paper pipe 111 is not fixed so as not to move with respect to the support means, and is supported with a certain amount of shakiness, so that it can vibrate with respect to the support means.

  The plurality of paper pipes 111 have appropriate flexibility, and upper and lower ends integrated by a pipe joint 112 are supported by a paper pipe case 119 and a connection plate 113, and a substantially central portion in the vertical direction is formed. It is only supported by the central support member 160, and is not supported as a whole. That is, the plurality of paper pipes 111 have supported support portions (upper and lower end portions and a substantially central portion) and unsupported flexible portions (parts other than the upper and lower end portions and the substantially central portion). .

  As described above, at least a part of the paper pipe 111 (for example, the flexible portion) is bent by the movement of the game ball 11 to be transported or the like, or the paper pipe case 119 as the support means, the connection plate 113 or the like. By virtue of the vibration, the contact between the game balls 11 and the contact between the game ball 11 and the biodegradable material layer 1111 as an abrasive member forming the inner surface of the paper pipe 111 are promoted. Since it adheres to the biodegradable material layer 1111 provided on the inner surface of the pipe 111 and is easily removed, the polishing effect can be improved.

  In particular, the inner diameter L10 (about 12 mm) of the paper pipe 111 is larger than the diameter 2R (about 11 mm) of the game ball 11 (L10> 2R), so that at least a part of the paper pipe 111 is bent. The game ball 11 is easily moved in the direction intersecting the axis of the paper pipe 111 inside the paper pipe 111 by virtue of the vibration or the support means, and thereby the biodegradable material layer 1111 and the game ball 11 is further promoted. In the present embodiment, the difference between the inner diameter L10 (about 12 mm) of the paper pipe 111 and the diameter 2R (about 11 mm) of the game ball 11 is about 1 mm, but it may be less than 1 mm, As long as the diameter of the sphere 11 is less than 2R, it may be 1 mm or more.

  In this embodiment, since the paper pipe 111 is inserted into the large diameter portion 140b with play, the paper pipe 111 is provided so as to be able to vibrate with respect to the pipe joint 112. Without being limited thereto, the paper pipe 111 may be inserted into the pipe joint 112 so as not to vibrate, that is, may be fixed.

  In the above-described embodiment, the pipe unit 150 is supported so as to be able to vibrate by arranging the pipe joints 112 at the upper and lower end portions with a gap from the paper pipe case 119 and the connection plate 113. The present invention is not limited to this. If the flexible portion of the paper pipe 111 is vibrated by bending, the pipe joint 112 is disposed without a gap with respect to the paper pipe case 119 and the connection plate 113. It may be fixed so as not to vibrate. Note that the paper pipe 111 may be fixed so as not to vibrate over the entire length in the longitudinal direction of the paper pipe 111 without bending the flexible portion of the paper pipe 111.

  Further, in the above-described embodiment, the plurality of paper pipes 111 are supported so as to be able to vibrate by having a substantially central portion in the longitudinal direction being disposed with a gap between the paper pipe case 119 and the central support member 160. However, the present invention is not limited to this. If the flexible portion of the paper pipe 111 is vibrated, the central portion of the plurality of paper pipes 111 in the longitudinal direction is vibrated. However, it may be fixed so as not to vibrate by being disposed with no gap with respect to the central support member 160.

  As described above, the paper pipe 111 is fixed to the pipe joint 112 so as not to vibrate, and the pipe joint 112 is fixed to the paper pipe case 119 and the connection plate 113 so as not to vibrate. Even if the substantially central portion in the longitudinal direction is fixed to the central support member 160 so as not to vibrate, the plurality of paper pipes 111 may not be fixed to the fixed portions (upper and lower end portions and substantially central portion). If there is a flexible portion (a portion other than the upper and lower end portions and the substantially central portion), the flexible portion of the paper pipe 111 is bent by the movement of the game ball 11 being pumped, that is, it can vibrate. The contact between the biodegradable material layer 1111 and the game ball 11 is promoted.

  In the above-described embodiment, the main lifting unit 110 has the flexible paper pipe 111, but the present invention is not limited to this, and the flexible pipe ( For example, the pipe may be made of a synthetic resin material or a metal material. Even in this case, if the pipe is supported by the paper pipe case 119 and the connection plate 113 or the central support member 160 with play, the pipe is moved relative to the support means by the movement of the game ball 11 being lifted. Since vibration is possible, contact between the biodegradable material layer 1111 and the game ball 11 is promoted. Furthermore, in this case, the entire region in the longitudinal direction of the main lifting unit 110 may be supported.

  In the above-described embodiment, the paper pipe 111 is disposed with a gap from the paper pipe case 119, the connection plate 113, and the central support member 160. However, the present invention is not limited to this, and the paper pipe 111 is not limited thereto. If the pipe 111 can vibrate with respect to the support means, for example, an elastic member (for example, a rubber material or a compression spring) that can be elastically deformed may be provided in the gap S <b> 2 or the like.

  In the above-described embodiment, the upper and lower end portions of the paper pipe 111 and the substantially central portion in the vertical direction are supported by the support means. However, the present invention is not limited to this, and various places are supported. Only one of the upper and lower end portions and the substantially central portion in the vertical direction may be supported, or a portion other than the three locations of the upper and lower end portions and the substantially central portion in the vertical direction is supported. May be.

  In the above-described embodiment, the biodegradable material layer 1111 formed on the inner surface of the cylindrical body 1112 is described as an example of the polishing member used on the inner surface of the paper pipe 111. However, the present invention is limited to this. Instead of this, the polishing member may not be formed on the inner surface of the cylinder 1112, and the game balls 11 may be removed from the inner surface of the cylinder itself constituting the paper pipe 111.

  Further, the present invention is not limited to the case where the biodegradable material layer 1111 is formed on the inner surface of the cylinder 1112, and an abrasive member layer such as the biodegradable material layer 1111 is integrally formed in advance on at least the inner surface of the cylinder 1112. It may be.

  Further, as shown in FIG. 12, the substantially central portion of each paper pipe 111 in the longitudinal direction is arranged with a gap with respect to the center support member 160 and the paper pipe case 119, and the paper pipe 111 moves the game ball 11. When the paper pipe 111 is bent, the center support member 160 and the paper pipe case 119 are contacted and supported only when the paper pipe 111 is bent. As a result, the paper pipe 111 can be supported easily to vibrate. Further, since the vibration range of the paper pipe 111 is limited by contact with the central support member 160 and the paper pipe case 119, the paper pipe 111 is prevented from being excessively bent and damaged.

  Further, in this embodiment, the biodegradable material layer 1111 as the polishing member that forms the inner surface of the paper pipe 111 of each of the main pumping sections 110 is made of the same material, but the present invention is not limited to this. However, the biodegradable material layer 1111 of at least two paper pipes 111 may be formed of different materials.

  For example, among the five paper pipes 111, the two paper pipes 111 and the three paper pipes 111 are made into paper pipes 111 having different properties, so that each paper pipe 111 supplements the conditions for exhibiting the polishing performance. Alternatively, one type of paper pipe 111 may be made of a material that easily removes oil, and the other type of paper pipe 111 may be made of a material that easily removes static electricity that causes dust adhesion.

  As shown in the modification of FIG. 32, the main pumping unit is composed of a lower first main pumping unit 110A and an upper second main pumping unit 110B, and the main pumping unit is configured in two upper and lower stages. May be.

The paper pipes 111 and 111 'have different properties. In addition, you may comprise so that each paper pipe 111,111 'may supplement the conditions which exhibit polishing performance.

  In FIG. 32, for the sake of understanding, members corresponding to the paper pipe case 119 and the like, which are support means for the paper pipes 111 and 111 ', are omitted. In this modification, a lower paper pipe case 119 and an upper paper pipe case 119 corresponding to each of the first main pumping unit 110A and the second main pumping unit 110B are provided, and the paper pipe cases 119 of each other are provided. Are connected by a connecting member (not shown). Note that the lower paper pipe 111 and the upper paper pipe 111 ′ may be integrally housed and supported in one paper pipe case 119.

  As shown in FIG. 32, a pipe joint 112 'is provided at the upper end of the lower paper pipe 111, and the upper ends of the five lower paper pipes 111 are held by the pipe joint 112'. In addition, a pipe joint 112 ′ that is vertically inverted is provided at the lower end of the upper paper pipe 111 ′, and the lower ends of the five upper paper pipes 111 are held by the pipe joint 112 ′. Further, the pipe joint 112 ′ is provided with a through hole 140 composed of a small diameter portion 140 a and a large diameter portion 140 b.

  The pipe joints 112 ′ and 112 ′ are connected by connecting the screwing pieces 112 a and 112 a provided to each other with screws. The connected through holes 140 and 140 of the pipe joints 112 ′ and 112 ′ communicate with each other, and the game ball 11 lifted from the lower paper pipe 111 is connected to the through holes 140 of the pipe joints 112 ′ and 112 ′. , 140 to the upper paper pipe 111 ′.

  Note that the ball pressure from the upper game ball 11 applied to the game ball 11 in the paper pipes 111 and 111 ′ is larger as the game ball 11 is lower than the paper pipes 111 and 111 ′, and is smaller as the upper game ball 11. Therefore, in the upper second main lifting part 110B, the force with which the game ball 11 is pressed against the inner surface of the paper pipe 111 'is smaller than that of the lower first main lifting part 110A, so that dirt is difficult to remove.

  Therefore, the inner surface of the cylinder 1112 (see FIG. 9) of the paper pipe 111 ′ in the second main pumping section 110B arranged in the upper stage is the paper pipe of the first main pumping section 110A arranged in the lower stage from the upper stage. Preferably, it is coated with a coating material (for example, a fluororesin material, a polyacetal resin material, a polyamide resin material, etc.) having a lower dynamic friction coefficient or static friction coefficient than the inner surface of the cylindrical body 1112 of 111. As described above, since the coating material is formed on the inner surface of the paper pipe 111, a coating resin layer having a low dynamic friction coefficient or a static friction coefficient is formed, so that the game ball 11 becomes slippery and the game ball 11 The dirt is more difficult to remove, but the coating material adheres to the surface of the game ball 11 in contact with the coating material and becomes slippery. Therefore, the game balls 11 that have been lifted and discharged can easily flow down the baskets and the like disposed on the upper part of the game island 1, so that the occurrence of clogging of the balls can be suppressed.

  Note that the cylinder 1112 of the paper pipe 111 in the first main lifting unit 110A arranged in the lower stage may be coated with a coating material having a low dynamic friction coefficient or static friction coefficient.

  In this modification, a coating resin layer made of a resin material having a low dynamic friction coefficient or a static friction coefficient is formed on the inner surface of the cylinder body 1112. However, when the cylinder body 1112 is manufactured, the inner surface of the cylinder body 1112 has a dynamic friction coefficient. Alternatively, a coating resin layer having a low coefficient of static friction may be formed.

  Further, for example, the inner surface of the paper pipe 111 of the lower first main pumping unit 110A and the inner surface of the paper pipe 111 'of the second main pumping unit 110B upper than the first main pumping unit 110A are predetermined. It is preferable to be formed of a material having different conditions for exhibiting the polishing performance. The conditions for exhibiting the predetermined polishing performance are, for example, the humidity, temperature, electrostatic resistance, and in-air of the installation location (for example, a game arcade) of the first main transfer unit 110A and the second main transfer unit 110B. The amount of dust contained in the game ball 11 and the dirt component of the game ball 11 are included.

  For example, in the above-described embodiment, the example in which the polishing member capable of maintaining the internal humidity of the paper pipe 111 as much as possible is provided on the inner surface of the paper pipe 111, but the present invention is not limited thereto. On the contrary, a material that can easily remove the dirt of the game ball 11 may be used as the polishing member because it becomes easier to be charged when the humidity is lower.

  Specifically, examples of a material that can remove dirt on the game ball 11 better when the humidity is lower include a resin or an acrylic resin that is an acrylic fiber material such as polyacrylonitrile (PAN). it can.

  The paper pipe 111 using these polyacrylonitriles (PAN) as an abrasive member is more than the paper pipe 111 using the polylactic acid-based resin exemplified in the first embodiment as an abrasive member in a high humidity atmosphere (24 ° C., humidity 85%). Although the polishing performance (soil removal performance) is low, it has higher polishing performance (stain removal performance) than the polylactic acid resin in a low humidity atmosphere (24 ° C., humidity 15%).

  As described above, the use of a material having a high polishing performance at a low humidity as the polishing member makes it easy for the game ball 11 to rust when the humidity is high. Since ball clogging is likely to occur, it is preferable to keep it as dry as possible. Therefore, it is possible to perform good polishing while maintaining a dry state suitable for these game balls 11.

  In addition, when a polishing member using a material that can remove dirt on the game ball 11 better when the humidity is lower, moisture on the surface of the game ball 11 just before entering the paper pipe 111 is removed. A dehumidifying device may be provided. By providing the dehumidifying device, it is possible to promote the removal of dirt on the game ball 11. Moreover, you may make it replace with the humidification apparatus 600 (refer FIG. 2) mentioned later, and to provide the apparatus which can switch and perform humidification and dehumidification.

  In the first embodiment, the polylactic acid resin has sufficient polishing performance, although the polishing performance is slightly lower than that of polyacrylonitrile (PAN) in a low humidity atmosphere (24 ° C., humidity 15%). In addition, it has good removal performance even in a high humidity atmosphere (24 ° C, humidity 85%), and since the polishing performance in the humidity atmosphere does not change significantly, stable polishing performance can be obtained, so the change in humidity When it is used in a place or time when the size of the material is large, it can be said that it is preferable to use a polylactic acid resin as the polishing member.

  As described above, the polishing performance varies greatly depending on the humidity or the like depending on the polishing member used. Therefore, there is a possibility that the dirt on the game ball 11 is not sufficiently removed due to the change in humidity. Therefore, for example, when the material of the inner surface of the paper pipe 111 of the lower first main lifting unit 110A is the first humidity (for example, high humidity), the polishing performance is high, and the second humidity (for example, low humidity) In this case, when the material is low in polishing performance, the inner surface of the paper pipe 111 ′ of the upper second main transport unit 110B may be made of material having high polishing performance in the case of the second humidity (for example, low humidity). .

  Further, in the state where a plurality of paper pipes 111 are bundled, when the humidity of the outside air becomes high, the material of the inner surface of the paper pipe 111 disposed on the outside is the first humidity (for example, high humidity). In the case where the polishing performance is high and the second humidity (for example, low humidity) is used, a material having low polishing performance may be used. Further, when the humidity of the outside air is low, the material of the inner surface of the paper pipe 111 disposed on the inner side is high in polishing performance when the first humidity (for example, high humidity), and the second humidity (for example, low) In the case of (humidity), a material having low polishing performance may be used.

  By doing in this way, even if it becomes 2nd humidity (for example, low humidity) and the grinding | polishing performance of 110 A of 1st main pumping parts becomes low, the 2nd main pumping part 110B is high. By having the polishing performance, it is possible to prevent the game ball 11 from being lifted up without being sufficiently polished due to a change in humidity while improving the normal polishing state. That is, the condition that each paper pipe 111, 111 'exhibits the polishing performance is compensated.

  The material of the inner surface of one of the plurality of paper pipes 111 is a material having a high polishing performance at a first temperature (for example, a high temperature) and a low polishing performance at a second temperature (for example, a low temperature). In this case, the inner surface of the other paper pipe 111 may be made of a material having a high polishing performance at the second temperature (for example, a low temperature). By doing in this way, even if the polishing performance of one paper pipe 111 becomes low because the temperature in the amusement hall becomes the second temperature (for example, low temperature), the other paper pipe 111 has high polishing performance. Thus, it is possible to prevent the game ball 11 from being lifted without being sufficiently polished due to a change in temperature while increasing the normal polishing state.

  Further, for example, since the lifting motor 404 (see FIG. 18) of the lifting device 100 is likely to generate heat, the material of the inner surface of the paper pipe 111 is used in the lower first main lifting unit 110A in the vicinity of the lifting motor 404. Is made of a material having a high polishing performance when it is at a first temperature (for example, a high temperature), and the material of the inner surface of the paper pipe 111 is separated in the upper second main lifting unit 110B away from the lifting motor 404 of the lifting device 100. If the material is made of a material having a high polishing performance at the second temperature (for example, a low temperature), the game ball 11 is lifted without being sufficiently polished by a change in temperature while improving the normal polishing state. Not only can it be suppressed, but high polishing performance is exhibited in the lower first main pumping section 110A, so that the polishing effect can be improved.

  In the above-described embodiment, an example in which materials having different humidity and temperature at the installation place (for example, amusement arcade) of the paper pipes 111 and 111 ′ is applied as a condition for exhibiting the predetermined polishing performance is described. As mentioned above, materials with different polishing performance depending on whether they are easily charged or hard to be charged, or materials with different polishing performance when the amount of dust contained in the air is large or small In addition, a material whose polishing performance is different between when the main component of the dirt of the game ball 11 is the first component and when it is the second component is applied to one of the plurality of paper pipes and the other paper pipe, respectively. Also good.

  In addition, you may make it change the color of the exterior of each paper pipe 111 for every paper pipe 111 from which a property differs. In this way, when a plurality of paper pipes 111 are configured, an operator can easily identify which paper pipe 111 has which property.

  In addition, for example, a piston vibrator capable of generating linear vibration from the reciprocating motion of a piston with a built-in air cushion, or a weight with a biased center of gravity on the output shaft of the motor is attached to the main pumping part, etc. The pipe unit 150 may be forcibly vibrated by applying a vibrator that generates vibration or a vibrator that generates high-speed vibration by sliding a ball bearing, a roller, or the like inside the casing. By doing so, the contact between the game balls 11 and the contact between the inner surface of the paper pipe and the game ball 11 are promoted by the vibration, whereby the dirt of the game ball 11 is easily attached to the inner surface of the paper pipe and removed. As a result, the polishing effect can be improved.

  Further, in the above embodiment, the material of the paper pipe 111 (cylinder 1112) of the main pumping unit is paper such as cardboard, so that it can be easily replaced and disposed of when it becomes dirty. However, the present invention is not limited to this, and the material of the pipe of the main pumping unit may be other as long as it is a flexible material. For example, it may be a rubber, a flexible resin, or a fiber. In addition, although the polishing effect of the game ball 11 due to the bending described above cannot be expected, a material having no flexibility, for example, a resin with little flexibility (for example, an acrylic resin) is used as a material for the pipe of the main lifting portion. Etc.), metal, wood, ceramic and the like may be used.

  Moreover, in the said 1st form, the overlap width of the strip | belt shaped object was made small with 0.3 mm. In this case, the thickness of the most part of the biodegradable material layer 1111 is the same as the thickness of the strip. For this reason, the biodegradable material layer 1111 can be prevented from becoming thick. However, the present invention is not limited to this, and the overlap width may be 1.5 cm with respect to a 3 cm wide strip. In this way, since the thickness of the biodegradable material layer 1111 is twice the thickness of the strip, the water vapor transmission rate can be about ½ times. Further, if the overlap width is 2 cm with respect to a 3 cm wide strip, the thickness of the biodegradable material layer 1111 is three times the thickness of the strip, so that the water vapor permeability is increased to about 1/3. be able to. Similarly, if the overlap width is Y with respect to the strip of width X, the thickness of the biodegradable material layer 1111 is X / (XY) times the thickness of the strip, so that the water vapor transmission rate is It can be about (XY) / X times. In this way, even if the water vapor permeability of the strip is high, the water vapor permeability of the biodegradable material layer 1111 can be lowered.

  Moreover, in the said Example, the biodegradable material layer 1111 of the paper pipe 111 of a main pumping part was formed by winding a strip | belt-shaped body helically. However, the present invention is not limited to this, and the belt-like body is wound perpendicularly to the longitudinal direction of the cylindrical body 1112 to form one step, and the edges of the adjacent ones of the steps are overlapped with each other, or the adjacent ones of the steps. Each step may be formed with a gap.

  Further, when a strip (film) is pasted on the inner surface after the cylindrical body 1112 is formed into a cylindrical shape, it is more efficient to form it by spirally winding it. However, in the case where the belt-like body is pasted in a developed state before the cylindrical body 1112 is formed into a cylindrical shape, the effort does not change whether it is wound spirally or wound perpendicularly to the longitudinal direction of the cylindrical body.

  Further, a strip-like body having a length in the longitudinal direction of the cylindrical body 1112 may be attached in parallel to the longitudinal direction. In this case, the entire circumference of the cylindrical body 1112 may be covered with a single belt-like body, or may be covered with a plurality of belt-like bodies. For example, one strip may be pasted every 90 degrees, and four strips may be pasted so as to cover the entire circumference.

  In these cases, the edges of adjacent strips may be overlapped, or a gap may be provided between adjacent strips. In this case, the overlapped portion and the longitudinal direction of the gap are parallel to the longitudinal direction of the cylinder 1112, and thus are substantially parallel to the flow of the game ball 11, but the game ball 11 is parallel to the longitudinal direction of the cylinder 1112. Since it also rotates in a direction perpendicular to the game ball 11, dirt on the game ball 11 can be removed at the overlapping portion and the gap.

  Alternatively, a biodegradable material film 1111 having a predetermined shape (for example, a rectangle, an ellipse, or a polygon) may be attached to the inner surface of the cylindrical body 1112 to form the biodegradable material layer 1111. For example, when pasting a 2 cm square rectangular film piece, since the circumferential length of the inner surface is 12 mm × π = about 37.7 mm, the circumferential direction can be covered with two pieces, The overlap width is (2 cm × 2-37.7) / 2 = 1. Further, a stepped portion where the film pieces overlap each other or a gap portion between the film pieces can be provided every about 2 cm in the longitudinal direction.

  For this reason, compared with the case where the biodegradable material layer 1111 is formed of a 2 cm wide band, more stepped portions or gap portions can be provided, and more dirt is accumulated in the stepped portions or gap portions. More dirt on the game ball 11 can be removed by the dirt adsorption force.

  Moreover, in the said Example, the inner surface of the biodegradable material layer 1111 shall be smooth. However, the present invention is not limited to this, and the inner surface of the biodegradable material layer 1111 does not need to be smooth, and may be embossed, rough, or very short (several μm ) The surface may have a protrusion. If it is not smooth, it is considered that the action of removing the dirt of the game ball 11 becomes higher.

  Further, in the embodiment, all the longitudinal direction of the cylindrical body 1112 of the paper pipe 111 of the main feed unit 110 is formed of a flexible material, and is fixed in the longitudinal direction of the paper pipe 111. The fixing portion (the portion fixed by the central support member 160) and the flexible portion that is weakly fixed or not fixed (the portion not fixed by the central support member 160) are included. It is not limited to, a part of the longitudinal direction of the pipe of the main lifting part 110 is formed of a material having flexibility, and the other part is formed of a material having no flexibility, While the portion formed of the material having no flexibility is fixed, the portion formed of the material having flexibility may be weakly fixed or may not be fixed.

  In the second embodiment, the biodegradable material layer 1111 of the paper pipe 111 of the main transport unit 110 is a single layer. However, a biodegradable material layer may be further provided between the first layer and the cylinder 1112 so that the cylinder 1112 does not look into the gap between the strips of the biodegradable material layer 1111. In this way, the water vapor permeability of the paper pipe 111 can be further reduced.

  Even if a biodegradable material layer is provided on the first layer so as to cover the gap, the same effect can be obtained. Further, even in the above-described embodiment, the gap is considerably narrower than the width of the band-like body (1/100 when the gap is 0.3 mm with the 3 cm-wide band-like body in the above example), Since it is negligible, the water vapor permeability of the paper pipe 111 is hardly adversely affected.

  Next, a ball removing operation for removing the game ball 11 from the lifting path formed by the lower lifting unit 301, the main lifting unit 110, and the upper lifting unit 130 extending upward from the lifting device 100 ( Maintenance work) will be described with reference to FIGS.

  As described above, the game ball 11 collected by the collection unit 53 on the left side of the merging unit 50 flows down to the right along the inclination of the collection unit 53, the basket 43, and the basket 42, The flow-down direction (traveling direction) is folded back at the junction 50 and flows down toward the left, and flows into the lifting device 100 via the ridge 60 (see FIG. 1).

  As shown in FIG. 14 (A), above the basket 42 that is the collection path for the game balls 11, the game balls are removed when the game balls 11 are pulled out from the transport path such as the main transport section 110. A collection box 51 for collecting 11 is provided. The collection box portion 51 has substantially the same front-rear dimension as the entire length of the arrangement range in the front-rear direction of the two lower lifting portions 301 arranged apart from each other in the front-rear direction.

  Further, as shown in FIG. 14B, a communication hole 51a communicating with the flange 42 is formed at the center of the bottom surface of the collection box portion 51, and the bottom surface of the collection box portion 51 is Inclined surfaces 51b and 51b are formed on the front and rear sides so that the side is high and the central portion is low. The game ball 11 collected in the collection box 51 flows down the front and rear inclined surfaces 51b and 51b and flows into the communication hole 51a in the center. The distance from the front ball opening 310 to the communication hole 51a and the distance from the rear ball opening 310 to the communication hole 51a are substantially the same. Further, the width in the left-right direction of the collection box 51 is substantially the same on the front side and the rear side of the communication hole 51a. Therefore, the front and rear inclined surfaces 51b and 51b can cause the same amount of game balls 11 to flow down to the communication hole 51a within the same time.

  Note that the lower lifting unit 301 disposed between the lifting device 100 and the main lifting unit 110 includes a game ball that exists in the lower lifting unit 301, the main lifting unit 110, and the upper lifting unit 130. A ball-opening opening 310 for pulling out 11 is provided. And the side surface which faces the lower lifting part 301 side in the collection box part 51 is formed with a notch part in which a position corresponding to the ball opening 310 provided in the lower lifting part 301 is notched.

  When the lifting device 100 is driven to lift the game ball 11, the ball opening 310 is closed by the closing plate 311. When the upper and lower edges of the closing plate 311 are held by the holding plate portion 312, the closing plate 311 is held at the position of the ball opening portion 310, and when the worker slides the holding plate portion 312 in the horizontal direction, 310 is opened. When the ball opening 310 is opened, the game balls 11 existing in the lower lifting unit 301, the main lifting unit 110, and the upper lifting unit 130 flow into the collection box unit 51 at once. Yes. The front and rear closing plates 311 and 311 that close the front and rear ball opening openings 310 and 310 are pulled out inward (center in the front and rear direction) so that both of the closing plates 311 and 311 can be pulled out simultaneously. It is like that. Therefore, the front and rear ball opening 310, 310 can be opened simultaneously.

  In the present embodiment, when the two front and rear ball opening openings 310 and 310 are opened, the game ball 11 flows down along the bottom surface of the collection box 51, and the game flows from both ball opening openings 310 and 310. As the balls 11 merge at the center of the bottom surface of the collection box 51 and collide with each other, the flow-down speed of the game ball 11 is reduced. Therefore, it is possible to prevent a large amount of game balls 11 from flowing into the lifting device 100 at a high speed.

  In addition, the game balls 11 that have joined at the center of the bottom surface of the collection box portion 51 once flow into the bowl 42, flow down from the bowl 42 in the right direction along the slope, and the joining section 50. In Fig. 1, the flow-down direction (traveling direction) is folded back and flows down to the left, and flows into the lifting device 100 through the ridge 60 (see Fig. 1). Therefore, the flow-down speed of the game ball 11 that has flowed from the basket 42 is decelerated by turning the traveling direction back at the junction 50, so that a large amount of the game ball 11 flows into the lifting device 100 at a high speed. Can be prevented.

  Furthermore, the collection box 51 is provided with a drive confirmation lamp 99 that is turned on when the lifting device 100 is driven. That is, the drive confirmation lamp 99 is provided in the vicinity of the ball extraction opening 310. Note that the position near the ball opening 310 indicates a range in which the operator can visually recognize the drive confirmation lamp 99. The operator can determine whether or not the lifting device 100 is being driven by checking the driving confirmation lamp 99, and erroneously opens the ball extraction opening 310 while the lifting device 100 is being driven. I try not to open it.

  In the present embodiment, the drive confirmation lamp 99 is provided, but the present invention is not limited to this, and a notification unit is provided for notifying that the lifting device 100 is being driven by a notification sound. You may do it. Moreover, it may notify that the lifting device 100 is being driven by vibrating the lifting device 100.

  Further, the lower end of the lower lifting unit 301 is connected to a connection port 411 (see FIG. 18) provided on the upper surface of the lifting device 100, and the game ball 11 that is lifted and discharged from this connection port 411 is provided. In addition, it flows into a pumping passage 402B (see FIG. 21) formed inside the lower pumping unit 301. In the lower lifting portion 301, five lifting passages 402B are formed corresponding to the five game ball passage holes of the connection port 411. Further, the internal dimension of the lifting passage 402B is formed to be slightly larger than the diameter of the game ball 11, and the game balls 11 can pass one by one.

  As shown in FIG. 15 (A), in the lower lifting portion 301, five hole portions 302 corresponding to each lifting passage 402B are formed between the ball opening 310 and the lifting device 100. . A chain release member 500 for releasing the chained state of the game balls 11 in each of the transport passages 402B is attached to a portion of the hole 302 in the lower lift unit 301 (see FIG. 15B). .

  For example, before performing the ball removal work, a large amount of game balls 11 are chained in the inside of the lifting passage 402B of the lower lifting portion 301 and the main lifting portion 110 and the upper lifting portion 130 thereabove. Are piled up. When the ball extraction opening 310 is opened in this chained state, the game ball 11 flows out from the ball extraction opening 310, but the game ball 11 at a position lower than the lower side of the ball extraction opening 310 is a ball. It does not flow out of the extraction opening 310 and stays in the lifting passage 402B (see FIG. 17). Then, the game ball 11 falling from above collides with the game ball 11 staying in the lift passage 402B, and the impact force is transmitted to the lift device 100 via the game ball 11 chained downward. End up. Therefore, members such as the one-way clutch 405 and the sprocket 403 (see FIG. 21) inside the lifting device 100 may be damaged. Therefore, in this embodiment, when the ball removal operation is performed, the chain release member 500 is first attached to the lower lifting unit 301 so that the chain of the game balls 11 is released.

  16A is a perspective view showing the chain release member 500, FIG. 16B is a plan view showing the chain release member 500, and FIG. 16C is a side view showing the chain release member 500. FIG. The chain release member 500 has a main body portion 501 extending in the width direction of the lower lifting portion 301 (see FIG. 15B), and the front and rear ends of the lower lifting portion 301 are provided at the end portions of the main body portion 501. A locking piece 505 that is locked to the portion is provided. A magnet member 504 that is attracted to the lower lifting portion 301 made of a magnetizable metal such as iron is provided at the center of the main body portion 501, and the magnet member is attached to the main body portion 501 by the mounting member 503. 504 is attached. The chain release member 500 is detachably attached to the lower lifting unit 301 by the attractive force of the magnet member 504.

  The main body portion 501 is formed with five comb-shaped insertion convex portions 502 corresponding to the five hole portions 302 of the lower lifting portion 301 and inserted into the respective hole portions 302. When attaching the chain release member 500 to the hole 302 of the lower lifting part 301, the chain release member 500 is moved by the magnet member 504 with the insertion protrusions 502 inserted into the hole 302. Attach to 301.

  As shown in FIG. 17, the hole 302 of the lower lifting part 301 is a long hole extending in the vertical direction, and the chain release member 500 is moved upward with the insertion convex part 502 inserted into the hole 302. When moved to, the chain state of the game balls 11 is released. In addition, since the chain cancellation | release member 500 is attached to the lower lifting part 301 by the magnet member 504, the operation | work which moves the chain cancellation | release member 500 upward can also be performed easily. Note that when the chain release member 500 is moved upward, the chain release member 500 is guided by the locking piece 505, so that the chain release member 500 can be moved without being displaced.

  Even if the game ball 11 falling from above collides with the game ball 11 staying in the lifting passage 402B when the ball extraction opening 310 is opened in a state where the chain of the game balls 11 is released, the impact It is possible to prevent the force from being received by the chain release member 500 and the impact force from being transmitted to the lifting device 100 via the game balls 11 chained downward.

  In this embodiment, the chain release member 500 is attached to the lower lifting unit 301 by the magnet member 504. However, the present invention is not limited to this, and the chain release member 500 is moved to the lower lift unit 301. When attached to the feeding portion 301, a movable attachment hook member or the like may be engaged with the hole 302, and the attachment hook member or the like is engaged with the lower end side of the hole 302. The chain release member 500 may be prevented from moving downward.

  As described above, in the polishing apparatus having the main lifting part 110 and the upper lifting part 130 in the present embodiment, the slide connecting part 132 of the upper lifting part 130 shown in FIG. Therefore, the paper pipe 111 is deformed by changing the longitudinal dimension of the paper pipe 111 by being held in a state of being pressed toward the pipe joint 112 at the upper part of the main lifting part 110. Can be prevented.

  Further, in this embodiment, in the modification shown in FIG. 32, the lower first main pumping unit 110A and the upper second main pumping unit 110B are configured, and the main pumping unit is configured in two upper and lower stages. Since the plurality of paper pipes 111 are connected by the pipe joints 112 ′ and 112 ′ by polishing the game ball 11, it is possible to prevent the occurrence of problems due to the deviation of the paper pipe 111.

  Further, in this embodiment, the slide connecting portion 132 of the upper lifting portion 130 is attached to the retaining piece 114 in the cylindrical support portion including the paper pipe case 119 and the connecting plate 113 via the spring 134 of the catch clip 133. By being locked, the paper pipe 111 is surrounded by a cylindrical support portion made up of the paper pipe case 119 and the connection plate 113. Therefore, even if the paper pipe 111 is held by pressing, the paper pipe 111 is prevented from falling off. be able to.

  Further, in this embodiment, as shown in the modification of FIG. 32, two types of paper pipe 111 in the lower first main transport unit 110A and paper pipe 111 ′ in the upper second main transport unit 110B. Paper pipes 111 and 111 ′ are provided, and each of the paper pipes 111 and 111 ′ is configured to compensate for the conditions for exhibiting the polishing performance, so that one paper pipe 111 cannot exhibit the predetermined polishing performance. Even if the conditions are satisfied, the other paper pipe 111 ′ pipe can exhibit a predetermined polishing performance, so that it is possible to prevent the game ball 11 from being lifted without being sufficiently polished depending on the conditions.

  In addition, in this embodiment, as shown in FIG. 6, the paper pipes 111 are arranged side by side and bundled, and in the modification, each paper pipe 111 supplements the conditions for exhibiting the polishing performance. With this configuration, even if one paper pipe 111 is in a condition where the predetermined polishing performance cannot be exhibited, the other paper pipe 111 ′ pipe can exhibit the predetermined polishing performance. It is possible to prevent the pumping from being carried out without being sufficiently polished.

  Further, in this embodiment, as shown in FIG. 10, the gap portion where the cylindrical body 1112 is exposed and the portion of the biodegradable material layer 1111 supplement each polishing performance, so that one paper pipe 111 is provided. However, since the other paper pipe 111 ′ pipe can exhibit the predetermined polishing performance even if the predetermined polishing performance cannot be exhibited, the game ball 11 is prevented from being lifted without being sufficiently polished depending on the conditions. be able to.

  In the present embodiment, the biodegradable material layer 1111 is formed inside the cylindrical body 1112, so that the inner surface of the paper pipe 111 is gradually roughened over time as the biodegradable material layer is biodegraded. Since the attracting force that has been reduced due to a large amount of dirt is restored, the dirt can be adsorbed again, so that the game ball 11 can be more suitably polished inside the paper pipe 111.

  Further, in the present embodiment, as shown in the modification of FIG. 32, the inner surface of the cylinder 1112 of the paper pipe 111 ′ in the second main lifting section 110B arranged in the upper stage is arranged below the upper stage. The ball pressure applied from the game ball 11 above the lower stage is coated with a coating material having a lower dynamic friction coefficient or static friction coefficient than the inner surface of the cylinder 1112 of the paper pipe 111 of the first main lifting part 110A. Since the coating is applied to the surface of the game ball 11 that is in contact with the coating material by applying the coating on the weak upper paper pipe 111 ′, the raised game ball 11 is likely to flow down.

  In the present embodiment, the game ball 11 extracted from the ball opening 310 is provided with a collection box 51 for returning the game ball 11 to the entrance side of the lifting device 100, so that the game existing inside the paper pipe 111.

The game ball 11 existing inside the paper pipe 111 is caused to flow down and flow down toward the left in the merging portion 50 and flow down toward the left and flow toward the lifting device 100 via the cage 60. Since the flow down speed of the game ball 11 flowing into the entrance of the lifting device 100 is decelerated by turning back the traveling direction, the game ball 11 flows into the entrance of the lifting device 100 at a stroke It is possible to prevent the device 100 from being damaged.

  In the present embodiment, as shown in FIG. 14, the game balls 11 joined at the center of the bottom surface of the collection box portion 51 flow into the basket 42, so that the game balls 11 existing inside the paper pipe 111 are removed. At the time of extraction, the flow-down speed of the game ball 11 flowing into the entrance of the lifting device 100 is reduced by merging in the collection box 51 and colliding with each other, so that the game ball 11 immediately enters the entrance of the lift device 100. It can prevent flowing in and damaging the lifting device 100.

  Further, in the present embodiment, as shown in FIG. 14A, a drive confirmation lamp 99 is provided in the collection box 51, so that a ball for extracting the game ball 11 existing inside the paper pipe 111 is extracted. The opening operation of the extraction opening 310 can be performed while confirming the operation of the lifting device 100 by the drive confirmation lamp 99.

A plurality of connection ports 411 corresponding to the respective game ball passages are formed on the upper surface of the fourth passage member 424, and first connection passages 402 </ b> A composed of a plurality of cylindrical game ball passages are formed from the connection ports 411. It extends to a position slightly below the center position in the vertical direction. A concave portion 440 having an arc shape when viewed from the front is formed below the first lifting passage 402A on the right side surface of the fourth passage member 424. The concave portion 440 is open to the right side. A plurality of guide surfaces 424a of the passage 401 are arranged side by side corresponding to each game ball passage.

  A vertically long insertion hole 443 is formed in the left side wall 441 at a position corresponding to the lower part of each game ball path of the first lifting path 402A, and each insertion hole 443 has a part of a one-way clutch 405 described later. Is inserted so as to protrude into the game ball passage (see FIG. 20).

  A plate-shaped guide wall 444 that protrudes to the right is formed at a position corresponding to the lower part of each game ball passage of the first lifting passage 402A on the right side wall 442. The guide wall 444 is disposed at a substantially central position in the front-rear width direction of each game ball passage of the first lifting passage 402A, and the lower surface has an arc shape in front view along an arc centering on the rotation shaft 430 of the sprocket 403. An arc surface 444a is formed, and the arc surface 444a is inclined with respect to the longitudinal direction of the first feed passage 402A. The guide wall 444 including the circular arc surface 444 a is disposed along the longitudinal direction of the first lifting passage 402 </ b> A and the rounded passage 401.

  Further, as shown in FIG. 21, the lower portion of the guide wall 444 is located at a position corresponding to the concave groove 433 in each ball receiving portion 432 of the sprocket 403, and the arc surface 444 a is more than the outer periphery of the cylindrical member 431 in the sprocket 403. By being arranged so as to enter the rotation shaft 430 side, the game balls 11 are held in contact with the ball receiving portions 432 and the guide surfaces 424a to be separated from the ball receiving portions 432, and It is possible to guide from the rounded passage 401 to the first lifting passage 402A.

  An elastic member 450 formed in a plate shape with a metal material such as stainless steel is attached to the guide wall 444. As shown in FIG. 22C, the elastic member 450 extends in the front-rear direction connecting the elastic piece portion 450A disposed along the circular arc surface 444a of each guide wall 444 and the upper end of each elastic piece portion 450A. The connecting piece portion 450B is formed in a comb-like shape. A mounting piece 450C is bent toward the left from the upper part of the front and rear elastic pieces 450A, and screw holes are formed in the connecting piece 450B and the mounting piece 450C. It is fixed to the guide wall 444.

  The elastic piece portion 450A is arranged in an inclined manner so as to be bent from the lower end of the first piece 451a to the left side along the arc surface 444a by hanging downward from the connecting piece portion 450B. Two pieces 451b, a third piece 451c bent obliquely upward and leftward from the lower end of the second piece 451b, and a fourth piece 451d bent substantially horizontally from the upper end of the third piece 451c to the second piece 451b side , Is composed of. The second piece 451b is bent and inclined with respect to the first piece 451a by a predetermined angle θ1 (for example, θ1 = about 45 degrees), and the third piece 451c is formed at a predetermined angle (for example, θ2 = about 15 with respect to the perpendicular). Degrees). Thus, the lower part of the elastic piece 450A is formed in an upward hook shape. Further, bent portions 452a and 452b which are bent downward are formed at two locations of the second piece 451b.

  As shown in the enlarged view in FIG. 23A, when the elastic member 450 is fixed to the guide wall 444 with a screw (not shown), each second piece 451b is disposed along each arc surface 444a, and the bent portion 452a and 452b come into contact with the arcuate surface 444a. As described above, the elastic member 450 is a guide formed on the right side wall 442 facing the inner surface 441a continuously provided from the terminal end of the guide surface 424a among the left side wall 441 and the right side wall 442 constituting the first lifting passage 402A. Attached to the wall 444, the second piece 451b is disposed so as to be inclined downward toward the left side wall 441. In addition, the third piece 451c and the fourth piece 451d, which are the lower ends of the elastic piece portion 450A, are disposed so as to protrude from the inner surface 442a on the first lifting passage 402A side of the right side wall 442 toward the passage side.

  At this time, the third piece 451c is provided so as to be inclined toward the left side wall 441 toward the upper end from the lower end, that is, the direction in which the game ball 11 is conveyed, and from the bent portion of the third piece 451c and the fourth piece 451d. A separation width dimension L <b> 1 between the left side wall 441 and the inner surface 441 a on the first lifting passage 402 </ b> A side is smaller than the diameter of the game ball 11.

  Further, the elastic piece portion 450A is disposed at a position corresponding to the concave groove 433 in each ball receiving portion 432 of the sprocket 403 so as to enter the rotation shaft 430 side from the outer periphery of the cylindrical member 431 in the sprocket 403. Thus, the game ball 11 conveyed by being held by each ball receiving portion 432 and the guide surface 424a collides with the third piece 451c.

  Each elastic piece 450A of the elastic member 450 is configured to be elastic with a strip-shaped metal piece, so that the game ball 11 that has been conveyed through the rounded passage 401 as described above is the third. When the game ball 11 comes into contact with the piece 451c, the game ball 11 is detached from the ball receiving portion 432 and guided to the first lifting passage 402A, and when the guided game ball 11 passes through the third piece 451c, the game ball 11 11 presses the third piece 451c toward the right side wall 442, the third piece 451c is elastically deformed to allow the game ball 11 to pass, and after the game ball 11 passes through the third piece 451c, the elastic force When the third piece 451c returns to the left side wall 441 side, the passed game ball 11 is held on the fourth piece 451d and dropped, that is, backflow is prevented.

  In this way, the elastic member 450 guides the game balls 11 from the rounded passage 401 to the first lifting passage 402A and sends them one by one, and the gaming balls 11 sent to the first lifting passage 402A fall downward. Thus, it is held so as not to flow back into the rounded passage 401, and constitutes the second backflow prevention means in this embodiment.

  As shown in FIG. 21, the one-way clutch 405 is a clutch mechanism that transmits a rotational force only in one direction. Although not specifically illustrated, for example, between the outer ring (outer race) and the inner ring (inner race). It has a structure that incorporates a dart-shaped ring stopper called sprag, and when the outer race rotates to one side with respect to the inner race, the sprag engages and transmits torque, and when it rotates in reverse, the sprag is disengaged A sprag type one-way clutch that does not transmit torque, an outer ring and an inner ring, a roller, and a spring are provided, and a pocket having a cam surface is provided inside the outer ring or outside the inner ring. A roller is disposed inside the pocket, and is kept in contact with the cam surface of the outer ring and the outer side of the inner ring or the cam surface of the inner ring and the inner side of the outer ring by a spring. When the outer ring tries to rotate in one direction with respect to the inner ring, the contact surface pressure between the cam surface and the roller increases, and the resistance is transmitted to the inner ring. When rotating in the reverse direction, the contact surface pressure between the cam surface and the roller becomes low, and a cam-type one-way clutch that slides and cuts power transmission can be applied.

  In the one-way clutch 405 of the present embodiment, a sprocket 405A having a plurality of ball receiving portions formed on the periphery is configured as an outer ring, and the sprocket 405A corresponds to each game ball passage in the lower part of the first lifting passage 402A. A plurality of juxtapositions are provided so as to be rotatable in one direction (counterclockwise when viewed from the front) and non-rotatable in the reverse direction (clockwise when viewed from the front) around a rotation shaft 405B extending in the front-rear width direction. The rotation shaft 405B is supported by front and rear walls of a cover member 405C provided to cover the insertion hole 443 on the left side surface of the fourth passage member 424, and the plurality of sprockets 405A are covered with the cover member 405C. Yes.

  Further, a part of the periphery of each sprocket 405A is provided so as to protrude into the first lifting passage 402A through the insertion hole 443, and the game ball 11 is placed between the ball receiving portion and the inner surface 442a of the right side wall 442. Rotate while holding to allow upward movement. Even if the game ball 11 held between the ball receiving portion and the inner surface 442a of the right side wall 442 cannot be pushed up by the lower succeeding ball, the game ball 11 held by the sprocket 405A has a reverse direction (front view clock). Therefore, the game ball 11 is held at the same position to prevent backflow.

  In this embodiment, the one-way clutch 405 is applied as the first backflow preventing means for preventing the backflow of the game ball 11 in the first lifting passage 402A. However, the present invention is not limited to this. In addition to the clutch mechanism that transmits the rotational force only in one direction, as long as it allows the upward movement of the game ball 11 and disables the downward movement, a backflow prevention member such as the elastic member 450, etc. Other backflow prevention means may be applied.

  As shown in FIG. 25, the drive unit 100 </ b> A configured as described above removes the first to fifth passage members 421 to 425 constituting each game ball passage by removing the front wall 434, and thereby the fourth passage member. Since the first to third passage members 421 to 423 and the fifth passage member 425 except for 424 can be taken out forward, and the fourth passage member 424 can be taken out to the left side, the sprocket 403 has the first to fifth passage members 421. With ˜425, it can be pulled out forward in the direction of the rotation axis 430.

  As described above, since the first to fifth passage members 421 to 425 and the sprocket 403 can be easily removed by removing the front wall 434, the guide passage 400, the round passage 401, and the first lifting passage 402A are used. Maintenance work can be easily performed when a ball clogging occurs or when a foreign object such as a nail enters.

  Next, the conveyance situation of the game ball 11 in the drive unit 100A configured as described above will be described.

  In the lifting device 100 of this embodiment, for example, when the game ball 11 is detected by a sensor (not shown) provided at the inlet 410, the cage 60, or the like, the sprocket 403 is rotated clockwise by the lifting motor 404. When the state where the game ball 11 is not detected continues for a predetermined time after the sensor (not shown) no longer detects the game ball 11, the sprocket 403 by the lift motor 404 is started. The rotation is stopped and the feeding is stopped. In the present embodiment, the sprocket 403 is rotated and the lifting of the game ball 11 is started when the game ball 11 flows into the inlet 410 as described above. However, the sprocket 403 may be continuously rotated from the start to the end of the game hall regardless of the inflow state of the game balls 11.

  First, as shown in FIG. 26, when the game ball 11 that has flowed down the bowl 60 from the merging portion 50 and has flowed into the inlet 410 flows down the guide passage 400 and reaches the rounded passage 401, the ball ball of the sprocket 403 is received. When the sprocket 403 is rotated by entering the portion 432 and being held by the guide surfaces 422a, 423a, 424a and the ball receiving portion 432, the rounded passage 401 is conveyed. Then, when reaching between the rounded passage 401 and the first lifting passage 402A, the elastic member 450 restricts the movement in the circumferential direction so as to be separated from the ball receiving portion 432 and from the downstream end portion of the guide surface 424a. Guided to the first lifting passage 402A extending upward.

  As shown in FIG. 27, the lower part of the game ball 11 conveyed to the first lifting passage 402A is supported by the elastic member 450, and the backflow from the first lifting passage 402A to the rounded passage 401 is prevented. And stays in the first pumping passage 402A. Each time the succeeding ball is guided to the first lifting passage 402A, the succeeding ball is pushed upward, and a plurality of game balls 11 stay in the first lifting passage 402A in a daisy chain state. Further, when there is no following ball, the lower part of the lowermost game ball 11A among the game balls 11 in the first lift passage 402A is supported by the elastic member 450, so that it is held in the first lift passage 402A. Thus, backflow is prevented.

  Further, when the game ball 11 whose lower part is supported by the fourth piece 451d of the elastic member 450 is pushed up by the succeeding ball, the game ball 11 comes into contact with the peripheral edge of the sprocket 405A of the one-way clutch 405 to rotate the sprocket 405A. It is held between the ball receiving portion 405A and the inner surface 442a of the right side wall 442. Here, since the sprocket 405A is restricted from turning clockwise when viewed from the front, if the sprocket 405A is held between the ball receiving portion of the sprocket 405A and the inner surface 442a of the right side wall 442, it moves downward, that is, backflow Is blocked.

  In the present embodiment, among the game balls 11 that have passed through the elastic member 450 and are transported to the first lifting passage 402A, the lower portion of the game ball 11A supported by the fourth piece 451d and the game ball 11A The load of the upper game ball 11B acts on the elastic member 450, and the load of the upper game ball 11 including the game ball 11C above the game ball 11B acts on the ball receiving portion of the sprocket 405A.

  That is, the load of the plurality of game balls 11 including the game ball 11C above the sprocket 405A of the one-way clutch 405 acts on the sprocket 405A, and two game balls 11A between the sprocket 405A and the elastic member 450 , 11B acts on the elastic member 450.

  Further, the game ball 11A supported from below by the elastic member 450 is completely detached from the outer periphery of the sprocket 403, so that even if the rotation of the sprocket 403 is continued without the subsequent ball, it contacts the outer periphery of the sprocket 403. Thus, there is no risk of damaging the sprocket 403.

  Next, the deformation state of the elastic member 450 when the game ball 11 is conveyed from the rounded passage 401 to the first lifting passage 402A will be described based on FIGS. 30 and 31. FIG.

  First, as shown in FIG. 30A, the game ball 11D held between the ball receiving portion 432 of the sprocket 403 and the guide surface 424a is formed between the rounded passage 401 and the first lifting passage 402A. When it reaches the connecting portion (the end of the rounded passage 401), it collides with the third piece 451c of the elastic member 450. Here, if the elastic member 450 is not provided, the ball receiving portion 432 is changed to an upward posture after passing through the end portion of the rounded passage 401, so that the game ball 11D is held in the ball receiving portion 432 by its own weight. Although the sprocket 403 is conveyed in the circumferential direction as it is, the elastic member 450 is disposed so as to enter the rotation shaft 430 side from the outer periphery of the sprocket 403, so that the game ball 11D is moved in the circumferential direction. Movement is prevented.

  In addition, as shown in FIG. 30 (B), the game ball 11D collides with the third piece 451c of the elastic member 450 and is prevented from moving in the circumferential direction, while the sprocket 403 is rotated. By being pushed upward by the lower edge of the portion 432, the second piece 451b is pushed rightward. At this time, the elastic piece 450A is biased toward the inner surface 441a by the elastic force of the elastic piece portion 450A, that is, away from the sprocket 403, so that the third piece 451c gradually moves away from the ball receiving portion 432 to the inner surface 441a. While being pressed, the third piece 451c is slidably guided upward.

  The elastic piece 450A is deformed toward the right side at the lower end side around the bent part of the first piece 451a and the second piece 451b, and moves away from the arc surface 444a along with the deformation. It is also possible to bend at the bent portions of the portions 452a and 452b or the second piece 451b and the third piece 451c, so that only the bent portion of the first piece 451a and the second piece 451b is loaded and the bent portion Is prevented from being easily broken.

  Next, as shown in FIG. 31 (A), when the center point P0 of the game ball 11 is located above the upper end position of the third piece 451c, the predetermined portion of the lower half of the outer surface of the game ball 11D is directed to the inner surface 411a side. Therefore, even if the game ball 11D is detached from the ball receiving portion 432 and cannot be pushed up, the game ball 11D is pushed up by the elastic force of the elastic piece portion 450A.

  Then, as shown in FIG. 31 (B), the game ball 11D passes through the third piece 451c, two points of the bent part of the third piece 451c and the fourth piece 451d and the inner surface 441a or the fourth piece 451d It is supported at two points with the inner surface 441a and held at the lower part of the first lifting passage 402A. This prevents the game ball 11D from dropping downward, that is, backflow from the first lifting passage 402A to the rounded passage 401. At this time, the game ball 11 </ b> D is completely detached from the ball receiver 432, and therefore does not come into contact with the outer periphery of the sprocket 403. In addition, in the front view, it seems that the game ball 11D is in contact with the outer periphery of the sprocket 403, but the outer periphery of the game ball 11D and the outer periphery of the sprocket 403 are in contact as shown in the plan view of FIG. Not. Therefore, when the sprocket 403 continues to rotate without the subsequent sphere being conveyed, the elastic member 450 prevents the reverse flow from being raised to the one-way clutch 405 although it is conveyed to the first lifting passage 402A. It is possible to prevent the game ball 11D being in contact with the outer periphery of the sprocket 403 and damaging the sprocket 403.

  As described above, in the lifting device 100 according to the present embodiment, the rounded passage 401 having the substantially arc-shaped guide surface 424a for guiding the game ball 11 and the upper end of the rounded passage 401 upward. A lifting passage 402 composed of an extending first lifting passage 402A and a second lifting passage 402B, a sprocket 403 as a rotating body rotatably provided at a position facing the guide surface 424a, and rotating the sprocket 403 A lifting motor 404 as a driving means for causing the game ball 11 between the sprocket 403 and the guide surface 424a to move from the rounded passage 401 to the first lifting. A lifting device 100 that is transported to a feeding path 402A and pushes up and lifts the game ball 11 in the first lifting path 402A. A one-way clutch 405 serving as a first backflow prevention means for preventing the game ball 11 from flowing back downward from the predetermined position, and being provided closer to the rounded passage 401 than the one-way clutch 405. And an elastic member 450 serving as a second backflow prevention means for preventing the game ball 11 that has been transported to the sending path 402A but not lifted up to the one-way clutch 405 from flowing back into the round path 401.

  By doing so, the one-way clutch 405 serving as the first backflow preventing means prevents the game ball 11 lifted up to a predetermined position in the first lifting passage 402A from being backflowed. It is possible to prevent the load of the game ball 11 lifted upward from being applied to the sprocket 403 and to apply a load to the lift motor 404, and to the one-way clutch 405 of the one transported from the rounded passage 401 to the first lift passage 402A. The non-lifted game ball 11 is prevented from flowing back to the rounded passage 401 by the elastic member 450 serving as the second backflow prevention means, so that the game ball 11 that has not been lifted up to the one-way clutch 405 flows back. Thus, the sprocket 403 can be prevented from coming into contact with and being damaged.

  In the present embodiment, the second backflow prevention means is constituted by the elastic member 450 formed so as to be elastically deformable, so that it is necessary to mount a complicated mechanism such as a one-way clutch mechanism. Since the structure is simple and the sprocket 403 can be placed closer to the right side wall 442 on the sprocket 403 side in the first lifting passage 402A, the game ball 11 immediately after the ball receiver 432 is detached. It becomes possible to support the lower part of the back and prevent backflow.

  Further, in this embodiment, the elastic member 450 as the second backflow preventing means causes the game ball 11 held by the ball receiving portion 432 to be detached and guided to the first lifting passage 402A. Since the game ball 11 does not directly collide with the right side wall 442 or the like, the right side wall 442 is not damaged, and the impact caused by the collision with the game ball 11 is buffered by the elastic deformation by the elastic member 450. Therefore, generation of contact sound and vibration can be suppressed.

  In the present embodiment, the game ball 11 at the lowest position among the game balls 11 transferred to the first lifting passage 402A is prevented from being backflowed by the elastic member 450 as the second backflow prevention means. Although the ball 11 does not come into contact with the sprocket 403, the present invention is not limited to this, and if the entire load of the game ball 11 whose backflow is prevented by the elastic member 450 is not applied, The game ball 11 may come into contact with the sprocket 403.

  In this embodiment, two game balls 11 are retained between the one-way clutch 405 and the elastic member 450. However, three or more game balls 11 may be retained, or only one ball may be retained. The arrangement interval between the one-way clutch 405 and the elastic member 450 may be changed so as to stay.

  Further, in this embodiment, the elastic member 450 configured to be elastically deformable with a metal piece is applied as an example of the second backflow prevention means. However, the present invention is not limited to this, and the game Other clutch mechanisms such as a one-way clutch similar to the one-way clutch 405 may be applied as long as the ball 11 is allowed to move upward and cannot be moved downward.

  Furthermore, the second backflow prevention means is not limited to an elastic member configured to be elastically deformable. For example, the second backflow prevention means protrudes into the first lifting passage 402A to prevent the backflow of the game ball 11 and the first lift. A blocking member provided so as to be movable between a retreat position for retreating from the feeding path 402A and a biasing means such as a spring for constantly biasing the blocking member toward the blocking position are provided, and the game ball 11 is When moving from the path 401 to the first lifting path 402A, the passage is allowed to retreat to the retreat position against the biasing force of the biasing means, and when the game ball 11 passes, the biasing force of the biasing means The movement of the game ball 11 from the first lifting passage 402A to the rounded passage 401 may be prevented by moving from the retracted position to the blocking position. The blocking member urged by the urging means in this way is also included in the elastic member.

  Further, instead of a biasing means such as a spring, a driving means for driving the blocking member so as to be movable between the blocking position and the retracted position may be applied, or according to the rotation of the sprocket 403. An interlocking mechanism that interlocks the blocking member so as to reciprocate between the blocking position and the retracted position may be applied.

  Further, the shape of the elastic member 450 is not limited to the shape described above, and can be variously modified.

  Further, the first lifting passage 402A includes a left side wall 441 as a first guide wall portion provided continuously with the guide surface 424a and a right side as a second guide wall portion disposed to face the left side wall 441. A biasing member having an elastic piece portion 450A as a backflow blocking portion provided so as to bias the game ball 11 from the right side wall 442 toward the left side wall 441. When the game ball 11 conveyed from the rounded passage 401 comes into contact with the third piece 451c of the elastic piece portion 450A, the game ball 11 is retreated against the right side wall 442 against the urging force. After passing the ball 11 and passing the game ball 11, the ball 11 is urged toward the left side wall 441 so that it protrudes to the lower position of the game ball 11 that has passed and supports the lower part of the game ball 11 to flow backward. To prevent.

  By doing so, the game ball 11 conveyed from the rounded passage 401 passes while being urged in the direction away from the left side wall 441, that is, the sprocket 403 by the third piece 451c of the elastic piece 450A. The game ball 11 whose backflow is prevented by the third piece 451c of the elastic piece portion 450A after passing can be made more difficult to contact the sprocket 403.

  Further, the rotating body is rotated from the rounded passage 401 by rotating in a state where a plurality of ball receiving portions 432 are formed in the circumferential direction and the game ball 11 is held between the ball receiving portion 432 and the guide surface 424a. 1 is a sprocket 403 that is conveyed to a lifting passage 402A. The sprocket 403 has a concave groove 433 formed continuously over a plurality of ball receiving portions 432, and at least the elastic piece portion 450A of the elastic member 450 is a concave groove. Since the elastic piece portion 450A can be disposed inside the sprocket 403 by being arranged at 433, not only can the drive unit 100A be made compact, but also the game ball 11 can be received by the ball receiving portion. Backflow can be prevented by being conveyed to the first lifting passage 402A while being smoothly separated from 432.

  In addition, the sprocket 403 can be detached from the drive unit 100A in the direction of the rotation shaft 430 by removing the fourth passage member 424 having the elastic member 450 from the drive unit 100A that is the main body of the lifting device 100. Maintenance work and the like of the sprocket 403 can be easily performed.

  Next, a humidifying device 600 that supplies moisture to the surface of the game ball 11 just before entering the paper pipe 111 of the main lifting unit 110 will be described with reference to FIGS. 2, 18 to 21, 26, and 27. To do.

  As shown in FIG. 2, a humidifier 600 is provided in the vicinity of the lifting device 100. The humidifier 600 is connected to the lifting device 100. The humidifier 600 includes a water tank (not shown) that stores water used for humidification, a sensor unit 604 that includes a temperature sensor that detects air temperature, a humidity sensor that detects air humidity, and the like, and the sensor unit 604. And a control circuit (not shown) for controlling humidification based on the detection information such as temperature and humidity acquired by the above.

  In this embodiment, it is a water spray type humidifier that humidifies the water at room temperature by making it into fine water droplets. A humidifier 600 of the type is used.

  As shown in FIGS. 18 to 21, 26, and 27, it corresponds to the upper part of each game ball passage of the first lifting passage 402 </ b> A in the fourth passage member 424 provided on the left side surface of the lifting device 100. A vertically long introduction hole 411b is formed at the position. Humidified air containing a large amount of moisture supplied from the humidifier 600 (hereinafter referred to as humidified air) is introduced into the first pumping passage 402A from the introduction hole 411b. Incidentally, five introduction holes 411b are formed corresponding to the five rows of the first lifting passages 402A.

  A cover member 601 is attached to the left side surface of the lifting device 100 so as to cover the introduction hole 411b in the fourth passage member 424 from the outside. This cover member 601 is a horizontally-long box-like member whose surface facing the introduction hole 411b is open, and a magnet member for adsorbing the cover member 601 to the left side surface of the lifting device 100 at both ends thereof. 603. The casing of the lifting device 100 is made of a magnetizable metal member such as iron, and the cover member 601 is detachably attached to the left side surface of the lifting device 100 by the magnet members 603 at both ends thereof. . Further, a hose member 602 extending from the humidifying device 600 is connected to the cover member 601, and humidified air is introduced from the humidifying device 600 into the cover member 601 through the hose member 602.

  When the humidifying device 600 is operated in a state where the cover member 601 is attached to the lifting device 100, humidified air is introduced from the humidifying device 600 into the cover member 601 through the hose member 602, and further the cover member 601. Humidified air is introduced into the first lifting passage 402A of the lifting device 100 from the inside through the introduction hole 411b.

  The humidified air introduced into the first pumping path 402A comes into contact with the game ball 11 in the first pumping path 402A, and moisture adheres to the surface of the game ball 11. Further, the humidified air introduced into the first pumping path 402A moves upward along the first pumping path 402A, which is the moving direction of the game ball 11, and passes through the lower pumping unit 301 to the main pumping unit. 110 enters the paper pipe 111. In addition, since moisture adhering to the surface of the game ball 11 also enters the paper pipe 111 as the game ball 11 enters, the inside of the paper pipe 111 has an appropriate humidity at which the degree of polishing of the game ball 11 is optimal. Will be kept.

  Thus, even in a state where the humidity of air (the air in the room of the game hall) is low, the inside of the paper pipe 111 is maintained at a humidity at which the degree of polishing of the game ball 11 is optimal. It is possible to prevent the game balls 11 from being lifted without being sufficiently polished without being sufficiently polished. In particular, the humidified air is supplied into the first lifting passage 402A immediately before the game ball 11 enters the paper pipe 111, so that the water pipe attached to the surface of the game ball 11 is evaporated before the paper pipe 111 is evaporated. The game ball 11 can be made to enter.

  In addition, the humidification apparatus 600 may supply humidified air as cool air that is lower than normal temperature (room temperature). For example, even when the game ball 11 is heated by a collision that occurs during transportation, if the humidified air supplied from the humidifier 600 is cold, the game ball 11 is cooled by the humidified air, and the game ball 11 can be prevented from evaporating at an early stage.

  The sensor unit 604 of the humidifying device 600 detects the temperature and humidity of the air near the lifting device 100. A control circuit (not shown) of the humidifier 600 controls the operation of the humidifier 600 based on detection information such as temperature and humidity acquired by the sensor unit 604. For example, the humidity of the air (the air in the room of the game hall) is high, and even if the humidified air is not supplied to the lifting device 100, the humidity of the game ball 11 by the paper pipe 111 is kept at an appropriate humidity that is optimal. If it is, the operation of the humidifier 600 is stopped. On the other hand, when the humidity of the air is low, the operation of the humidifying device 600 is started so that the degree of polishing of the game ball 11 by the paper pipe 111 is kept at an appropriate humidity.

  In the present embodiment, when the humidity detected by the sensor unit 604 is 60% or less, the humidifier 600 is controlled to start operating. In addition, the humidity used as the reference | standard of the operation | movement start of this humidifier 600 is not restricted to the setting of 60% or less, It can set suitably in the range of 45% or less-65% or less. In addition, the determination of “below” in the present embodiment may be determination of whether “low (small)” or “less than”. In addition, when the humidity detected by the sensor unit 604 is equal to or higher than the reference humidity, control for stopping the operation of the humidifier 600 may be performed. Further, the determination of whether or not “above” in this embodiment may be determination of whether or not “high (large)” or determination of “higher (excess)”.

  Further, since the cover member 601 is detachably attached to the lifting device 100, the cover member 601 is removed from the lifting device 100 during a period of high humidity (hours) such as summer (rainy season). The cover member 601 can be attached to the lifting device 100 during a period of low humidity (hours) such as winter (dry season). Therefore, it is possible for a store clerk of the game hall to operate the humidifier 600 by attaching the cover member 601 to the lifting device 100 only during periods of low humidity. In addition, by removing the cover member 601 from the lifting device 100, the humidifying device 600 can be easily maintained.

  In this embodiment, alkaline reduced water (electrolyzed water) is used as water stored in a water tank (not shown) in the humidifier 600 and used for humidification. This reduced water is water that is generated by splitting into positive-side acidic water and negative-side alkaline water when electricity is passed through the water. In this embodiment, alkaline reduced water having a hydrogen ion index (pH) of 8 to 10 is used. Note that strong alkaline reduced water having a hydrogen ion index (pH) of 11 or more may be used. The alkaline reduced water adheres to the game ball 11 so that the game ball 11 can be easily cleaned, and the lifting device 100 is configured as compared with the case where acidic reduced water or neutral water is used. The rusting of the member to be performed is suppressed.

  In this embodiment, alkaline reduced water (electrolyzed water) is used as water used for humidification, but the present invention is not limited to this, and even neutral water may be used as water used for humidification. It may be good or water obtained by mixing alkaline reduced water with neutral water.

  The game balls 11 collide with each other or come into sliding contact with members constituting the path of the game balls 11 so that the game balls 11 are charged to the plus side. By using alkaline reduced water (water negatively charged) as the water used for the humidified air supplied from the water, the water contained in the humidified air supplied from the humidifier 600 is easily adsorbed to the game ball 11. .

  As described above, in the polishing apparatus according to the present embodiment, the surface of the game ball 11 can maintain an appropriate amount of water by including the humidifier 600 that can supply moisture to the surface of the game ball 11. It is possible to prevent the game ball 11 from being sufficiently polished due to a significant decrease in moisture on the surface of the game ball 11.

  In the present embodiment, the humidifier 600 that can supply moisture to the air in the first lifting passage 402A, which is the path through which the game ball 11 passes, includes the humidifier 600, so that the air in the path through which the game ball 11 passes can be obtained. It is possible to maintain an appropriate amount of moisture, and to prevent the game ball 11 from being sufficiently polished due to a significant decrease in the moisture of the air in the path.

  In the present embodiment, the control circuit of the humidifying device 600 controls the operation of the humidifying device 600 based on detection information such as temperature and humidity acquired by the sensor unit 604, and humidifies the air when the humidity is low. By starting the operation of the apparatus 600, it is possible to prevent excessive supply of moisture, and to keep moisture suitable for polishing the game ball 11.

  Further, in this embodiment, since the cover member 601 of the humidifying device 600 is detachably attached to the lifting device 100, the humidity in the game hall is good for sufficiently polishing the game ball 11. In this case, the cover member 601 of the humidifying device 600 can be removed, and moisture can be supplied by attaching the cover member 601 of the humidifying device 600 as necessary.

  Further, in this embodiment, since the alkaline reducing water is stored in the water tank in the humidifying device 600 and used for humidification, polishing of the game ball 11 can be promoted and the rusting of the lifting device 100 is prevented. It can be prevented.

  In this embodiment, the humidified air is supplied from the humidifying device 600 into the first lifting passage 402A immediately before the game ball 11 enters the paper pipe 111, but the present invention is not limited to this. Instead, the game ball 11 may be supplied after the game ball 11 enters the paper pipe 111, and humidified air is supplied from the humidifier 600 while the game ball 11 is being lifted. The humidified air may be supplied from the humidifying device 600 to the game ball 11 at a position above the upper end of the paper pipe 111 after the 11 is lifted. Further, humid air may be supplied from the humidifying device 600 to the game ball 11 in the upper tank 70, or on the other game ball 11 path, for example, the supply path 80, the junction 50, or the recovery The humidifying air may be supplied from the humidifying device 600 to the game ball 11 in the parts 52 and 53, the baskets 43 and 42, and the like.

  In the present embodiment, the humidified air is supplied from the humidifier 600 into the first pumping passage 402A of the pumping device 100, but the present invention is not limited to this. In the feeding device 100, the humidified air may be supplied from the humidifying device 600 in the vicinity of the inlet 410 into which the game ball 11 flows, that is, in the vicinity of the inlet where the game ball 11 flows into the lifting device 100.

  In this embodiment, the humidified air is supplied from the humidifier 600 into the first pumping path 402A of the pumping apparatus 100, but the present invention is not limited to this, and the paper is not limited to this. The humidified air supplied from the humidifying device 600 may be sprayed from the outside of the pipe 111 toward the paper pipe 111, and the sprayed water penetrates to the inside of the paper pipe 111 and enters the game ball 11. It may supply water.

  Note that a heater or the like may be provided in the vicinity of the connection port 411 through which the game ball 11 is discharged from the humidifying device 600 to dry the game ball 11 to which moisture has adhered. For example, when the humidified air is excessively supplied from the humidifier 600, or when a large amount of moisture adheres to the surface of the game ball 11 due to condensation or the like due to the air humidity being too high, the humidifier The game ball 11 discharged from 600 may be dried by a heater or the like.

  In the present embodiment, the sensor unit 604 of the humidifying device 600 detects the temperature and humidity of the air in the vicinity of the lifting device 100, but the present invention is not limited to this. The section may detect the temperature and humidity of the air near the paper pipe 111, or may detect the temperature and humidity of the air in the paper pipe 111. Furthermore, the sensor unit may detect the temperature, humidity, and the like of air (in the amusement hall) at a position away from the lifting device 100.

  In the present embodiment, the ultrasonic humidifier 600 is used, but the present invention is not limited to this, and other types of humidifiers may be used. For example, it is a water spray type humidifier that humidifies by converting water at room temperature into fine water droplets, which is a centrifugal humidifier that mists water with the centrifugal force of a rotating disk and diffuses it with a blower, The water pressurized by the pump is blown into the equipment to evaporate, the water droplets are separated by the eliminator and the humidified air is blown by the high pressure spray type humidifier or the equipment pressurized by the air pressurized by the compressor. It may be a two-fluid spray type humidifier that ejects and evaporates.

  In addition, it is a vaporizing humidifier that humidifies by evaporating water at room temperature, and has a moisture-permeable humidifier that contacts water and air through a membrane that allows only water vapor to pass through.

Double-tube humidifier that blows steam generated from a heat source into a double pipe to separate impurities and water droplets and blows only moisture into the equipment. Water that has been treated with a deionizer with the heat of steam generated by a device or heat source is converted into clean steam by a steam generator and blown into the equipment, or water is thrown into the heater and heated by an electric heater. Electric heat humidifier that generates steam, pan-type humidifier that heats water in an evaporating dish (pan) with electricity or a steam heater, evaporates it and diffuses it in the air, or passes AC power through water Thus, an electrode-type humidifier that generates heat and generates steam may be used.

  Further, the humidified humidified air containing a large amount of moisture supplied from the humidifying device 600 in the present embodiment may be air containing a large amount of water vapor components, or air in a state where a large amount of fine water droplets are drifting. But it ’s okay.

  Further, in this embodiment, the humidifier 600 is provided in a pipe type polishing apparatus that polishes the game ball 11 using a paper pipe 111 (polishing pipe) and removes the dirt, and the surface of the game ball 11 or the game ball 11 is provided. Moisture is supplied to the path through which the game passes, but a humidifying device 600 is provided in a polishing device that polishes the game medium using resin pellets, and the surface of the game ball 11 and the game ball 11 pass therethrough. Moisture may be supplied into the path to be performed.

  The “moisture supply means” in the present invention is not limited to a humidifier for increasing the humidity of the air, but may be any other means as long as it supplies water to the surface of the game ball 11 or the path through which the game ball 11 passes. It may be the means. For example, it is a water spray device that sprays water in a spray form, and water may be sprayed onto the game ball 11 by the water spray device, or water may be sprayed into a path through which the game ball 11 passes. In addition, the game ball 11 just before entering the paper pipe 111 may be brought into contact with the game ball 11 by bringing a cloth or the like impregnated with water into contact therewith.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

  In the above-described embodiment, the case where the invention is applied to the polishing apparatus for lifting the game ball 11 has been described. However, as long as the game ball 11 is transported, the game ball 11 is not limited to lifting, and may be transported in the horizontal direction or transported in the downward direction.

  In the said Example, it demonstrated as invention of the grinding | polishing apparatus provided with the main raising part 110 (for example, paper pipe 111) for removing the surface dirt of the game ball 11 which flows through the inside. However, the present invention is not limited to this, and can be understood as an invention of the game island 1 in which such a polishing apparatus is installed.

  Moreover, it includes a lifting device 100, an upper tank, a lower tank, a cleaning device, and a transport pipe and a cage for connecting the respective devices. The game ball 11 is recovered from the pachinko gaming machine 10, polished, and pachinko. It can be understood as an invention of a system for supplying to the gaming machine 10. It can also be understood as an invention of the main lifting unit 110 (for example, a paper pipe 111).

  Moreover, in the said Example, although the cover member 601 is attached to the left side surface of the conveying apparatus 100 detachably by the magnet member 603 of the both ends, this invention is not limited to this, The cover member 601 May be detachably attached by a conventionally known method such as attachment by screwing or attachment using an adhesive.

  For example, in the above embodiment, the pachinko gaming machine 10 is illustrated as an example of the gaming machine, but the present invention is not limited to this. For example, a predetermined number of gaming balls are inside the gaming machine. The number of loaned balls that are enclosed in a circulating manner and lent in response to a loan request by a player and the number of prize balls that are awarded in response to winnings are added, while the number of game balls used in the game is subtracted. The present invention can also be applied to so-called enclosed game machines that are stored in the memory. In these enclosed game machines, not the game ball but points and points are given to the player, so these points and points assigned correspond to the game value. Further, in such an enclosed game machine, when circulating the game ball, a polishing device is provided for removing surface contamination of the game ball 11 flowing through the inside of the game machine, and the polishing device is a humidifier. The structure provided with may be sufficient.

  Moreover, in the said Example, when the humidity detected by the sensor part 604 is below a predetermined value, it is controlled so that the operation | movement of the humidification apparatus 600 is started, and whether the game ball 11 is lifted (polishing apparatus) The humidifying device 600 is operated regardless of whether or not the game ball circulates inside, but the present invention is not limited to this, and when the game ball 11 is being lifted Only when the game ball is circulating in the polishing apparatus, the humidifier 600 may be operated. By doing in this way, the electric power etc. which are required for operation | movement of the humidification apparatus 600 can be saved. Further, the humidifier 600 may be operated only when the game ball 11 is not lifted (only when the game ball is not circulating in the polishing apparatus). By doing so, it is possible to prevent the game ball 11 and the paper pipe 111 from being dried and dirt being fixed while the game ball is stuck in the paper pipe 111 of the main lifting unit 110.
