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.

  In addition, the upper end of the upper pumping part 130 is hold | maintained in the state which can be moved to the up-down direction in the insertion hole 77 provided in the upper tank 70 (refer FIG. 32 (A)). 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. When the paper pipe 111 is not bent or vibrated by the movement of the game ball, the central support member 160 or the paper pipe Although it does not contact the case 119, it is supported by contacting the central support member 160 and the paper pipe case 119 only when the paper pipe 111 bends or moves in the horizontal direction.

  As shown in FIG. 13, in this embodiment, when a lifting force is applied by the lifting device 100, a game ball (for example, the game ball 11) waiting in a daisy chain state in the paper pipe 111 is moved upward. It is pushed up to be lifted. 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 is applied to the lower game ball, the game balls are stacked with the center point P0 being shifted in the horizontal direction. Therefore, when a lifting force is applied by the lifting device 100, each game ball moves upward while slidingly contacting the inner surface of the paper pipe 111, and a rotating force is applied by the sliding contact to move the upper and lower games. The balls 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 moves upward in the paper pipe 111, vibration occurs due to the game ball orbiting 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 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 in the paper pipe 111 moving upward. Contact between the inner surface of the paper pipe 111 and the game ball is 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 in the paper pipe 111 moving upward, so that the contact between the game balls and the inner surface of the paper pipe 111 Contact with the game ball is promoted.

  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 will be described. Table 1 is a table showing components of dirt attached to paper pipes (polishing pipes) and baskets through which game balls pass. Table 2 is a table showing the components of dirt when moisture is removed from dirt attached to paper pipes and bags through which game balls pass. The dirt adhering to the paper pipe and the bag is a transfer of the dirt adhering to the game ball. The foreign matter A, the foreign matter B, and the foreign matter C are different stains at different locations.

  Referring to Table 1 and Table 2, the oil component is derived from mineral oil applied to each part through which the game ball 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 lactate. Mg, Al, Si, S, Cl, K, Ca, Cr, Ni, and Cu are derived from salts other than lactate.

  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 can be removed effectively.

  Here, the lactate such as sodium lactate is firmly attached to an attached object (for example, a game ball) when moisture is removed. In the pipe type polishing apparatus, unless the material of the polishing member used for the inner surface of the pipe is specified, moisture is removed from the dirt components adhering to the game ball. As a result, the dirt adhering to the game ball is removed. It makes it difficult to drop lactate. Therefore, in order to remove the dirt, it is important to leave moisture appropriately.

  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 being lifted. This bending promotes contact between the game balls and contact between the biodegradable material layer on the inner surface of the paper pipe 111 and the game ball, and also promotes change (biodegradation) of the contacted portion. As a result, it is possible to promote the removal of dirt from the game ball and improve the polishing effect.

However, if only the paper pipe 111 is used for the main lifting part 110, the water vapor permeability becomes high, and the moisture adhering to the game ball flowing through the inside is diffused to the outside of the paper pipe 111. . This further promotes the sticking of lactate to the game ball. 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 possible to easily leave moisture of dirt (for example, sodium lactate) adhering to the game ball, and as a result, it is easy to adsorb dirt. it can.

  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 of 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 Table 1 and Table 2, the dirt adhering to the game ball contains a large amount of sodium lactate, so that 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 dirt adhering to the game ball 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 a game ball becomes comparatively good, and can make this stain | pollution | contamination easy.

  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 coating agent, the affinity with the dirt attached to the game ball 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 attached to the game ball has moved to the paper pipe 111). In this way, the affinity between the biodegradable material layer or the coating agent and the dirt component is relatively improved, so that the dirt adhering to the game ball is removed. It can be easily adsorbed.

  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 the oil contained in the foreign matter A to C shown in Table 1 (that is, the dirt that has adhered to the game ball has moved to the paper pipe 111), and the oil content in weight percent close to the composition of the dirt component. As a result, 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 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 substances A to C shown in Table 1 (that is, the dirt attached to the game ball 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 mineral oil and / or sebum oil and the dirt component becomes relatively good, dirt adhering to the game ball 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 adhered to the game ball moved to the paper pipe 111) contain a fiber component that is a water-insoluble substance, and thereby, the biodegradable material layer or Since the affinity between the coating agent and the dirt component becomes relatively good, dirt attached to the game ball 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 a game ball to which the paper pipe 111 is fed.

  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 to be transported or the like, or against the paper pipe case 119 as the support means, the connection plate 113 or the like. By vibrating, the contact between the game balls 11 and the contact between the game balls and the biodegradable material layer 1111 as the polishing member that forms the inner surface of the paper pipe 111 are promoted. Since it adheres to the biodegradable material layer 1111 provided on the inner surface 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. Or the support means vibrates, so that the game ball can easily move in the direction intersecting the axis of the paper pipe 111 inside the paper pipe 111, whereby the biodegradable material layer 1111 and the game ball Contact 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 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 part (parts other than the upper and lower ends and the substantially central part), the flexible part of the paper pipe 111 is bent by the movement of the game ball being pumped, that is, it can vibrate, Contact between the biodegradable material layer 1111 and the game ball 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 vibrates with respect to the support means due to the movement of the game ball being lifted. Therefore, the contact between the biodegradable material layer 1111 and the game ball 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. The polishing member may not be formed on the inner surface of the cylinder 1112, and the game ball 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, a substantially central portion in the longitudinal direction of each paper pipe 111 is disposed with a gap with respect to the central support member 160 and the paper pipe case 119, and the paper pipe 111 is moved by the movement of the game ball. When the paper pipe 111 is bent, the central support member 160 and the paper pipe case 119 are contacted and supported only when the paper pipe 111 is bent. In this way, 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. 34, 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.

  In this modification, two types of paper pipes 111 and 111 ′ are provided, that is, a paper pipe 111 in the lower first main lifting unit 110A and a paper pipe 111 ′ in the upper second main lifting unit 110B. 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.

  Note that, in FIG. 34, in order to help 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. 34, 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 ′ are in communication with each other, and the game ball lifted from the lower paper pipe 111 is inserted into the through holes 140 and 140 ′ of the pipe joints 112 ′ and 112 ′. 140 is guided to the upper paper pipe 111 ′ via 140.

  Note that the ball pressure from the upper game ball applied to the game balls in the paper pipes 111 and 111 ′ is larger as the game balls are lower than the paper pipes 111 and 111 ′, and is smaller as the game balls are higher. Therefore, in the upper second main lifting part 110B, the force with which the game ball is pressed against the inner surface of the paper pipe 111 'is smaller than that in the lower first main lifting part 110A, so that the 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. Thus, since the coating material is formed on the inner surface of the paper pipe 111 to form a coating resin layer having a low dynamic friction coefficient or static friction coefficient, the game ball becomes slippery and the game ball becomes dirty. However, the coating material adheres to the surface of the game ball in contact with the coating material and becomes slippery. Therefore, since the game balls 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, the occurrence of ball clogging 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. Including the amount of dust contained in the game, dirt components of the game ball.

  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 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 the dirt of the game ball better when the humidity is lower include a resin that becomes an acrylic fiber material such as polyacrylonitrile (PAN), an acrylic resin, and the like. .

  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 to rust when the humidity is high, and at the cage provided on the game island 1 Since clogging is likely to occur, it is preferable to keep it as dry as possible. Therefore, good polishing can be performed while maintaining a dry state suitable for these game balls.

  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 greatly varies 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 may not be 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 from being lifted without being sufficiently polished due to a change in humidity while enhancing 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. As a result, it is possible to prevent the game ball 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), it is possible to prevent the game ball from being lifted without being sufficiently polished due to a change in temperature while improving the normal polishing state. In addition, the polishing effect can be improved because high polishing performance is exhibited in the lower first main pumping section 110A.

  In the above description, an example in which a material having different humidity and temperature at the installation location (for example, amusement arcade) of the paper pipes 111 and 111 ′ is applied as a condition for exhibiting the predetermined polishing performance is described above. As described above, materials that have different polishing performance depending on whether they are easily charged or hard to wear, materials that have different polishing performance when the amount of dust contained in the air is large or small, and games You may apply the material from which the grinding | polishing performance differs when the main component of a spherical stain | pollution | contamination is a 1st component and a 2nd component to one paper pipe and other paper pipes among some, respectively.

  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 and the contact between the inner surface of the paper pipe and the game ball are promoted by vibration, and this makes it easier for dirt on the game ball to adhere to the inner surface of the paper pipe and be removed. 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 due to the bending described above cannot be expected, a material having no flexibility, for example, a resin having almost no flexibility (for example, an acrylic resin, 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, since the longitudinal direction of the overlapped portion and the gap is parallel to the longitudinal direction of the cylinder 1112, it is substantially parallel to the flow of the game ball, but the game ball is perpendicular to the longitudinal direction of the cylinder 1112. Since it also rotates in any direction, it is possible to remove the dirt of the game ball 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 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. When it is not smooth, it is considered that the action of removing the dirt on the game ball 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 (maintenance) for removing a game ball from a lifting path constituted by a lower lifting unit 301, a main lifting unit 110, and an upper lifting unit 130 extending upward from the lifting device 100. (Work) will be described with reference to FIGS.

  As described above, the game balls collected by the collecting unit 53 on the left side of the merging unit 50 are caused to flow downward in the right direction along the inclinations of the collecting unit 53, the ridge 43, and the ridge 42. The flow-down direction (traveling direction) is folded back in the portion 50 and flows downward toward the left, and flows into the lifting device 100 via the ridge 60 (see FIG. 1).

  As shown in FIG. 14 (A), the game ball is collected above the cage 42, which is the game ball collection path, when the game ball is removed from the transport path such as the main transport unit 110. A recovery box 51 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 balls collected in the collection box 51 flow down the front and rear inclined surfaces 51b and 51b and flow 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 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 is provided for removing the ball. 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, 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 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. . 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 portions 310 and 310 are opened, the game ball flows down along the bottom surface of the collection box portion 51, and the game ball flows from both the ball opening portions 310 and 310. Are joined at the center of the bottom surface of the collection box 51 and collide with each other, so that the flow-down speed of the game ball is reduced. Therefore, it is possible to prevent a large amount of game balls from flowing into the lifting device 100 at a high speed.

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

  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.

  In addition, 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 a game ball lifted and discharged from the connection port 411 is 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, and the game balls 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 that releases the chained state of the game balls 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 carrying out the ball removal work, a large amount of game balls are chained in the inside of the transport passage 402B of the lower transport unit 301 and the main transport unit 110 and the upper transport unit 130 thereabove. It is piled up. When the ball extraction opening 310 is opened in this chained state, the game ball flows out from the ball extraction opening 310, but the game ball located at a position lower than the lower side of the ball extraction opening 310 is the ball extraction opening. It does not flow out of the portion 310 and stays in the lifting passage 402B (see FIG. 17). Then, the game ball that has fallen from the upper side collides with the game ball staying in the lifting passage 402B, and the impact force is transmitted to the lifting device 100 through the game ball chained downward. 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 to release the chain of game balls.

  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.

  As described above, in the polishing apparatus having the main lifting part 110 and the upper lifting part 130 as an embodiment of the present invention, the slide connecting part 132 of the upper lifting part 130 shown in FIG. 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 by the urging force. Can be prevented.

  Further, in this embodiment, in the modification shown in FIG. 34, 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 balls, it is possible to prevent the occurrence of problems due to the deviation of the paper pipes 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.

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 under the conditions, the other paper pipe 111 ′ pipe can exhibit a predetermined polishing performance, so that it is possible to prevent the game ball from being transported 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 when one paper pipe 111 cannot exhibit a predetermined polishing performance, the other paper pipe 111 ′ pipe can exhibit a predetermined polishing performance. It is possible to prevent the material from being fed without being 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, it is possible to prevent the game ball from being lifted up without being sufficiently polished depending on the conditions because the other paper pipe 111 ′ pipe can exhibit the predetermined polishing performance even under the conditions where the predetermined polishing performance cannot be exhibited. Can do.

  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 adsorbing force that has decreased due to a large amount of dirt adhering is restored, the dirt can be adsorbed again, so that the game ball can be more suitably polished inside the paper pipe 111.

  Further, in this embodiment, as shown in the modification of FIG. 34, the inner surface of the cylinder 1112 of the paper pipe 111 ′ in the second main pumping section 110B arranged in the upper stage is arranged below the upper stage. By coating 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, the ball pressure applied from the game ball above the lower stage is reduced. By coating the weak upper paper pipe 111 ′, the coating material adheres to the surface of the game ball in contact with the coating material and becomes slippery, so that the raised game ball can easily flow down.

  In the present embodiment, the game ball existing inside the paper pipe 111 is provided with the collection box 51 for returning the game ball extracted from the ball opening 310 to the entrance side of the lifting device 100. Therefore, the maintainability of the paper pipe 111 can be improved.

  Further, in this embodiment, as shown in FIG. 14A, the game balls that have joined together at the center of the bottom surface of the collection box portion 51 flow into the basket 42 and go rightward along the slope from the basket 42. The flow direction is turned back at the junction 50, and the flow direction is turned to the left and flows toward the lifting device 100 through the cage 60, whereby the game ball existing inside the paper pipe 111 is extracted. Sometimes, the flow speed of the game ball flowing into the entrance of the lifting device 100 is decelerated by turning back the traveling direction, so that the game ball flows into the entrance of the lifting device 100 at a stroke and breaks the lifting device 100. Can be prevented.

  Further, in this embodiment, as shown in FIG. 14, when the game balls joined at the center of the bottom surface of the collection box portion 51 flow into the basket 42, the game balls existing inside the paper pipe 111 are extracted. In addition, the flow velocity of the game balls flowing into the entrance of the lifting device 100 is reduced by joining and colliding with each other in the collection box 51, so that the game balls flow into the entrance of the lifting device 100 all at once. It is possible to prevent the feeder 100 from being damaged.

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

  Further, in this embodiment, as shown in FIG. 15, there is provided means for releasing the chain of game balls by inserting the insertion convex portion 502 of the chain release member 500 into the hole 302 of the lower lifting portion 301. Thus, when a game ball existing inside the paper pipe 111 is extracted, it is possible to prevent an impact caused by the game ball flowing down the paper pipe 111 from being applied to the lifting device 100.

It is provided facing the left side of the sprocket 403 so as to correspond to the spherical passage. Details of the fourth passage member 424 will be described later.

  The arcuate guide surfaces 422a, 423a, and 424a of the first to fourth passage members 422, 423, and 424 are provided so as to be continuous in the circumferential direction of the sprocket 403, and the guide surfaces 422a, 423a, and 424a are provided on the guide surfaces 422a, 423a, and 424a. A sprocket 403 is rotatably provided at the facing position. In detail, the guide surface 424a has a circular arc portion from the start end adjacent to the guide surface 423a to the left side position of the rotation shaft 430 of the sprocket 403, and the first lift from the end (upper end) of the circular arc portion. It is comprised from the linear part to the starting end (lower end) of the inner surface 441a (refer FIG. 23) of the channel | path 402A. That is, the first lifting passage 402A extends substantially vertically upward in the tangential direction passing through the end (upper end) of the arcuate guide surface 424a.

  In the present embodiment, the first lifting passage 402A and the second lifting passage 402B are disposed substantially vertically. However, the present invention is not limited to this, and the lifting device 100 is viewed from the front. As long as the game ball can be transported upward as seen, it may be extended obliquely upward.

  As shown in FIG. 24, the sprocket 403 includes a rotating shaft 430 facing in the front-rear direction, and a cylindrical member 431 fixed to the rotating shaft 430 around the rotating shaft 430 so as not to be relatively rotatable. ing. A plurality of substantially hemispherical concave ball receiving portions 432 capable of accommodating game balls are formed at predetermined intervals in the circumferential direction at positions corresponding to the respective game ball paths on the peripheral surface of the cylindrical member 431.

It is disposed at a position shifted in the circumferential direction with respect to 432. Specifically, a straight line passing through the center position of each ball receiving portion 432 adjacent in the axial direction of the rotation shaft 430 is disposed so as to be slightly inclined with respect to the axial center. As a result, it is avoided that all the game balls of each game ball passage guided by the guide passage 400 are accommodated in the ball receiving portion 432 at the same timing, so that the ball biting occurs simultaneously in each game ball passage. As described later, it is possible to avoid pushing up all the game balls in each game ball passage conveyed in the rounded passage 401 to the first lifting passage 402A at the same timing. It is possible to prevent the weight of the game balls in each game ball passage from being applied all at once and applying a load to the lifting motor 404.

  As shown in FIGS. 18 and 19, the sprocket 403 configured in this manner is rotatable on a front wall 434 (see FIG. 19) in which the front end of the rotation shaft 430 is erected on the front side of the drive unit 100 </ b> A. While being pivotally supported, the rear end is pivotally supported on a rear wall 435 (see FIG. 18) that is erected on the rear side of the drive unit 100A. Further, the rear end of the rotation shaft 430 penetrates the rear wall 435 and protrudes to the back side, and the driven gear 436 is fixed to the protruded rear end.

  Further, a lifting motor 404 is fixed to the upper right side position of the sprocket 403. The lift motor 404 is provided so that the drive shaft 404a penetrates the rear wall 435 and protrudes to the back side, and a drive gear 437 is fixed to the rear end protruding to the back side. The drive gear 437 is engaged with an intermediate gear 438 that is pivotally supported by the rear wall 435, and the intermediate gear 438 is also engaged with the driven gear 436. , The rotational force is transmitted to the rotation shaft 430 through the intermediate gear 438 and the driven gear 436, and the sprocket 403 is rotated.

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 rotating shaft 430 side, the game balls held on the ball receiving portions 432 and the guide surfaces 424a are brought into contact with the ball receiving portions 432 to be separated from the round shape. It is possible to guide from the 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 incline toward the left side wall 441 toward the upper end from the lower end, that is, the direction in which the game ball is transported, and left from the bent portion of the third piece 451c and the fourth piece 451d. A separation width dimension L1 between the wall 441 and the inner surface 441a on the first lifting passage 402A side is smaller than the diameter of the game ball.

  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 balls transported by being held by the respective ball receiving portions 432 and the guide surface 424a collide with the third piece 451c.

  Each elastic piece portion 450A of the elastic member 450 is configured to be elastic with a strip-shaped metal piece so that the game ball conveyed through the rounded passage 401 as described above is the third piece. When it comes into contact with 451c, the game ball is detached from the ball receiving portion 432 and guided to the first lifting passage 402A, and when the guided game ball passes through the third piece 451c, the game ball is third. By pressing the piece 451c toward the right side wall 442, the third piece 451c is elastically deformed to allow the passage of the game ball, and after the game ball passes through the third piece 451c, the third piece 451c is moved to the left side by the elastic force. By returning to the wall 441 side, the passed game ball 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 from the rounded passage 401 to the first lifting passage 402A and sends them one by one, and the gaming balls sent to the first lifting passage 402A fall downward. It holds so that it does not flow back into the rounded passage 401, and constitutes the second backflow prevention means of the present invention.

  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.

  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 holds the game ball between the ball receiving portion and the inner surface 442a of the right side wall 442. Rotate to allow upward movement. Even if the game ball 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 held by the sprocket 405A is reversed in the reverse direction (clockwise in front view). Therefore, the game ball is held in the same position to prevent backflow.

  In the present embodiment, the one-way clutch 405 is applied as the first backflow prevention means for preventing the backflow of the game ball in the first lifting passage 402A, but the present invention is not limited to this. Other than the clutch mechanism that transmits the rotational force only in one direction, if the game ball is allowed to move upward and cannot be moved downward, other members such as a backflow prevention member such as an elastic member 450 can be used. A 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 state of transport of game balls in the drive unit 100A configured as described above will be described.

  In the lifting device 100 according to the present embodiment, for example, when a game ball 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 is not detected continues for a predetermined time after the sensor (not shown) no longer detects the game ball, the sprocket 403 is rotated by the lift motor 404. Is stopped and the transport is stopped. In this embodiment, the sprocket 403 is rotated and the lifting of the game ball is started when the game ball flows into the inlet 410 as described above. The sprocket 403 may continue to rotate from the start to the end of the game hall regardless of the inflow situation of the game balls.

  First, as shown in FIG. 26A, when the game ball that has flowed down the spear 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 sprocket 403 The ball receiving portion 432 is entered, and the sprocket 403 is rotated to be conveyed through the rounded passage 401 while being held by the guide surfaces 422a, 423a, 424a and the ball receiving portion 432. 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. 26B, the lower part of the game ball transferred 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. As a result, it 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 stay in the first lifting passage 402A in a daisy chain. Further, when there is no following ball, the lower part of the lowest game ball 11A among the game balls in the first lifting passage 402A is supported by the elastic member 450 so that it is held in the first lifting passage 402A. This prevents backflow.

  Further, when the game ball, the lower part of which is supported by the fourth piece 451d of the elastic member 450, is pushed up by the succeeding ball, it contacts the periphery of the sprocket 405A of the one-way clutch 405, rotates the sprocket 405A, and the sprocket 405A Between the ball receiving portion 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 transferred to the first lifting passage 402A through the elastic member 450, the lower part is supported by the fourth piece 451d and the upper part of the game ball 11A. The load of the game ball 11B acts on the elastic member 450, and the load of the upper game ball 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 a plurality of game balls 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, The load 11B is applied to 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, a deformation state of the elastic member 450 when the game ball is conveyed from the rounded passage 401 to the first lifting passage 402A will be described based on FIGS. 29 and 30. FIG.

  First, as shown in FIG. 29A, 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.

  As shown in FIG. 29B, the game ball 11D collides with the third piece 451c of the elastic member 450 and is prevented from moving in the circumferential direction. 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. 30 (A), when the center point P0 of the game ball 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 toward the inner surface 411a. 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. 30B, the game ball 11D passes through the third piece 451c, and 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, the game ball 11D appears to be 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 apparatus 100 according to the embodiment of the present invention, the rounded path 401 having the substantially arc-shaped guide surface 424a for guiding the game ball, and the upper end of the rounded path 401 A lifting passage 402 composed of a first lifting passage 402A and a second lifting passage 402B extending upward, a sprocket 403 as a rotating body rotatably provided at a position facing the guide surface 424a, and a sprocket 403 A lifting motor 404 as a driving means for rotating, and when the lifting motor 404 rotates the sprocket 403, a game ball between the sprocket 403 and the guide surface 424 a is first transferred from the rounded passage 401. A lifting device 100 that is transported to a lifting passage 402A and lifts and lifts a game ball in the first lifting passage 402A, below the first lifting passage 402A. A one-way clutch 405 serving as a first backflow prevention means for preventing the game ball from flowing back downward from the predetermined position, and provided on the rounded passage 401 side with respect to the one-way clutch 405, and the first lifting passage 402A And an elastic member 450 as second backflow prevention means for preventing the game ball that has been transported to the one-way clutch 405 but is not backflowed 401 into the round path.

  By doing so, the one-way clutch 405 as the first backflow prevention means prevents the game ball that has been lifted up to the predetermined position in the first lifting passage 402A from flowing back, so that it is above the one-way clutch 405. It is possible to prevent the load of the game ball lifted on the sprocket 403 from being applied to the lift motor 404 and to lift it up to the one-way clutch 405 although it is conveyed from the rounded passage 401 to the first lift passage 402A. The game balls that have not been lifted up to the one-way clutch 405 are caused to flow backward and come into contact with the sprocket 403 by preventing the non-played game balls from flowing back to the rounded passage 401 by the elastic member 450 as the second backflow prevention means. And is prevented from being hurt.

  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 disposed closer to the right side wall 442 on the sprocket 403 side in the first lifting passage 402A, the game ball is immediately after being detached from the ball receiving portion 432. It is possible to support the lower part and prevent backflow.

  Further, in this embodiment, the elastic member 450 as the second backflow prevention means is configured to separate the game ball held in the ball receiving portion 432 and guide it to the first lifting passage 402A. Since the game ball does not directly collide with the right side wall 442 and the like, the right side wall 442 is not damaged, and the impact caused by the collision with the game ball is buffered by the elastic deformation by the elastic member 450. Generation of sound and vibration can be suppressed.

  In this embodiment, in the state where the lowest flow of the game balls transferred to the first lifting passage 402A is blocked by the elastic member 450 as the second reverse flow blocking means, The sprocket 403 is not in contact with the sprocket 403, but the present invention is not limited to this, and the gaming ball is not sprocketed as long as the entire load of the gaming ball whose backflow is prevented by the elastic member 450 is not applied. It may come into contact with 403.

  In this embodiment, two game balls are retained between the one-way clutch 405 and the elastic member 450. However, three or more game balls may be retained, or only one ball may be retained. As described above, the arrangement interval between the one-way clutch 405 and the elastic member 450 may be changed.

  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 is allowed to move upward and cannot be moved downward.

  Further, 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 and the first lifting A blocking member provided so as to be movable between a retracted position for retracting from the passage 402A and a biasing means such as a spring for constantly biasing the blocking member toward the blocking position are provided, so that the game ball is a round path. When moving from 401 to the first lifting passage 402A, it retreats to the retreat position against the urging force of the urging means to allow passage, and when the game ball passes, the urging force of the urging means moves from the retreat position. It may move to the blocking position and block the movement of the game ball from the first lifting passage 402A to the rounded passage 401. 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 from the right side wall 442 toward the left side wall 441. When the game ball conveyed from the rounded passage 401 comes into contact with the third piece 451c of the elastic piece 450A, the game ball is retreated against the right side wall 442 against the biasing force. After the game ball has passed, the game ball is biased toward the left side wall 441 so that it protrudes to a position below the game ball that has passed therethrough and supports the lower part of the game ball to prevent backflow.

  By doing so, the game ball 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. It is possible to make the game ball whose backflow is prevented by the third piece 451c of the elastic piece portion 450A after passing more difficult to contact the sprocket 403.

  In addition, the rotating body has a plurality of ball receiving portions 432 formed in the circumferential direction and rotates in a state where a game ball is held between the ball receiving portion 432 and the guide surface 424a, whereby the rotating body is first moved from the rounded passage 401. The sprocket 403 is conveyed to the 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 433. Since the elastic piece portion 450A can be disposed inside the sprocket 403, the drive unit 100A can be made compact, and the game ball can be removed from the ball receiving portion 432. Backflow can be prevented by being conveyed to the first lifting passage 402A while being smoothly separated.

  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, the structure of the upper tank 70 provided in the upper part of the game island 1 will be described with reference to FIGS.

On the left side of the box member 71, an upper lifting part 130 is extended from the bottom side of the box member 71, and two insertion holes 77 are provided before and after the upper end of the upper lifting part 130 is inserted. ing. The opening at the upper end of the upper lifting part 130 is exposed from the insertion hole 77, and the game ball 11 lifted to the upper end of the upper lifting part 130 flows into the upper tank 70 from the insertion hole 77. It is like that. Further, on the left side of the box member 71, a ball receiving portion 76 that receives the game ball 11 that has flowed in is provided. The bottom surface of the ball receiving portion 76 is formed with an inclined surface so that the front and rear sides are high and the central portion is low. In addition, the game ball 11 that has flowed into the ball receiving portion 76 flows into the storage portion of the box member 71 through an inclined rod 78 formed at the front and rear central portions of the ball receiving portion 76.

  As shown in FIG. 32 (B), in the storage part of the box member 71, a lower inclined plate 72 that forms the bottom surface of the box member 71 and an upper side of the lower inclined plate 72 are arranged and flowed down from the inclined rod 78. And an upper inclined plate 79 into which the game ball 11 flows. The upper inclined plate 79 is detachably attached to a mounting bracket 71 a provided on the inner side surface of the box member 71.

  Further, the upper inclined plate 79 is inclined so that the right side is lowered so that the game ball 11 flowing down from the inclined rod 78 flows down to the right side. The game ball 11 that has moved to the right end of the upper inclined plate 79 falls on the lower inclined plate 72. Furthermore, the upper inclined plate 79 is provided with a plurality of holes 79a, and the game ball 11 flowing down the upper surface of the upper inclined plate 79 falls to the lower inclined plate 72 from the plurality of holes 79a. Yes. In other words, the plurality of holes 79 a are formed in the upper inclined plate 79, so that the game ball 11 falls from the upper inclined plate 79 to the upper surface of the lower inclined plate 72 over the entire surface.

  Further, the lower inclined plate 72 is inclined so that the left side is lowered in order to cause the game ball 11 to flow down to the left side. Further, a discharge portion 74 for discharging the game ball 11 downward is connected to the left end side of the lower inclined plate 72. An opening 74 a of the discharge unit 74 is opened in the lower inclined plate 72. The game balls 11 are supplied to the supply path 80 from the discharge portion 74 extending below the lower inclined plate 72 via the connecting member 75 extending to the left and right, and the game balls 11 are supplied to each pachinko gaming machine 10 via the supply path 80. Is supplied.

  In addition, an empty detection sensor 81 that detects that the number of game balls 11 stored in the box member 71 is reduced or that the box member 71 is empty is provided at the lower right portion of the box member 71. ing. Further, a full tank detection sensor 82 for detecting that the game ball 11 stored in the box member 71 is full is provided on the upper left side of the box member 71. These detection sensors 81 and 82 are a photo sensor that detects the presence or absence of a game ball using light such as infrared rays, a contact sensor that detects the presence or absence of a game ball by contact with the game ball, a magnet, or the like. Known sensors such as a proximity sensor that detects proximity of a game ball using a member are used.

  The control device (not shown) of the lifting device 100 stops driving the lifting device 100 when the full tank detection sensor 82 is in an ON state, that is, when the game ball 11 is detected to be full. Control. And the said control apparatus performs the control which starts the drive of the lifting apparatus 100 again, when the full tank detection sensor 82 is an OFF state, ie, the game ball 11 has decreased.

  As shown in FIGS. 32 (B) and 33, an auxiliary inclined plate 73 that is inclined so that the right side is lowered is provided so as to cover the upper side of the opening 74 a of the discharge portion 74. The auxiliary inclined plate 73 is provided to prevent the game ball 11 from flowing smoothly when the upper tank 70 is filled with the game ball 11 and the ball pressure is concentrated on the opening 74a. ing.

  The auxiliary inclined plate 73 is arranged at a position away from the upper surface of the lower inclined plate 72 by a predetermined distance, and the game ball 11 flowing down on the lower inclined plate 72 flows down toward the opening 74a. ing.

  In addition, when the game ball 11 is stored in the upper tank 70 to the extent that it can be detected that the full tank detection sensor 82 is full, the game ball on the upper surface of the lower inclined plate 72 moves toward the opening 74a. The game balls on the upper surface of the auxiliary inclined plate 73 once flow down to the upper surface of the lower inclined plate 72 and then flow down toward the opening 74a. Therefore, the game ball 11 is likely to remain in the predetermined area X on the upper surface of the auxiliary inclined plate 73. Once the upper tank 70 is filled with the game ball 11, even if the game ball 11 decreases thereafter, It is difficult to release the ON state of the full tank detection sensor 82.

  Therefore, in the present embodiment, a notch hole portion 73a is formed in a portion corresponding to the upper position of the opening 74a and a part of the central portion of the auxiliary inclined plate 73 is notched. The game ball 11 remaining in the predetermined area X on the upper surface of the auxiliary inclined plate 73 easily flows down from the cutout hole 73a toward the opening 74a. Therefore, when the game ball 11 decreases after the upper tank 70 is filled with the game ball 11, the game ball 11 existing in the predetermined area X on the upper surface of the auxiliary inclined plate 73 is preferentially discharged from the opening 74a. Then, the full tank detection sensor 82 is immediately turned off, so that the lifting device 100 is driven again.
