This is the time required for discharging from 20, and is set to 30 seconds, for example. Further, the driving time is to drive the first roller 42 in the normal direction, so that the used portion of the polishing cloth 14 that is stretched over the facing portion (polishing feed path) from the upper end to the lower end of the guide rail is This is the time that can be pulled and moved so as to replace all unused portions, and is set to 45 seconds, for example.

  The rotation direction switch 53 is configured to be able to rotate and be positioned at three angular positions of “N (neutral)”, “forward rotation”, and “reverse rotation”. By pressing the start switch 51, the normal operation for replacing the used portion of the polishing pad 14 with the unused portion is set. On the other hand, when the position is set to “forward rotation” or “reverse rotation”, the tension motor 41 is driven to rotate forward or reversely regardless of the pressing operation of the start switch 51, and the polishing pad 14 is moved to an arbitrary position. It is set so that it can be pulled in the direction. As described above, in the case of “forward rotation”, the polishing pad 14 is dropped into the space 37a (the post-use storage body 56) of the post-use storage unit 37, and in the case of “reverse rotation”, the space 37a ( After use, the polishing pad 14 in the storage body 56) is pulled out. The emergency stop switch 54 is used in an emergency, and the tension motor 41 is forcibly stopped by pressing the stop switch 54.

(Effects of Example)
Next, the operation of the game ball lifting and polishing apparatus according to the above-described embodiment will be described.

  First, the setting work of the polishing pad 14 in the lift polishing apparatus 10 of the embodiment will be described. In the setting operation, the polishing cloth 15 is opened with respect to the transport belt 13, and the second roller 43 is positioned at the open position shown in FIG. Further, by hooking eyelets 57, 57 located on the front surface side of the post-use storage body 56 received through the entrance 37b of the post-use storage section 37, the hooks 59, 59 of the storage body installation section 60 are hooked. The post-use storage body 56 is held with its mouth portion 56a opened upward.

  The polishing cloth 14 is stored in a folded state, and the lower end of the pre-use storage box 30 whose front end is pulled out from the opening 30a in a vertical posture with the opening 30a facing upward. The part is inserted into the mounting part 26 from above. At this time, the lower end of the pre-use storage box 30 abuts against the regulating member 29 and is positioned, and the four sides are supported by the first and second support frames 27 and 28. 26 is mounted in a positioning state (see FIG. 3).

  In the pre-use storage box 30, the polishing cloth 14 is stored in a multi-layered state folded up and down, so that the installation space for the polishing cloth 14 before use is larger than in the conventional case where the polishing cloth 14 is wound into a roll. Can be reduced, and the size of the lift polishing apparatus 10 can be reduced. More specifically, the longer the polishing cloth 14 is, the larger the diameter when the polishing cloth 14 is made into a roll shape. Therefore, when the roll-like polishing cloth is installed at the rear part of the lifting and polishing apparatus 10, it protrudes backward. The amount becomes large, and it is necessary to secure a space for accommodating the part, and a large installation space must be secured. However, when the polishing cloth 14 is in a multi-layered state as in the embodiment, the thickness in the front-rear direction can be reduced, the amount of protrusion to the rear is suppressed, and the installation space for the lift polishing apparatus 10 is reduced. obtain. Further, when a roll-shaped polishing cloth is installed, so-called dead spaces are formed at the four corners and the shaft portion of the roll, but a state in which the rectangular parallelepiped pre-use storage box 30 is mounted on the mounting portion 26 as in the embodiment. Thus, there is no dead space and the space can be used effectively.

  The polishing pad 14 pulled out from the opening 30a of the pre-use storage box 30 is hung on the path guides 23, 23 of the guide unit 22 and on the upper guide roller 24, and then folded back to the front side of the cover case 21. It spans from the upper end to the lower end of the front surface of the guide rail. Further, the polishing cloth 14 folded back from the lower end of the guide rail is wound around the lower guide roller 39 and then guided upward (see FIG. 4), and between the first roller 42 and the second roller 43. Let us face you. That is, as shown in FIG. 9A, the polishing pad 14 that has passed the gap between the first roller 42 and the second roller 43 that is spaced rearward from the lower side to the upper side is moved to the upper part of the first roller 42. Wrap from the rear side to the front side, and the front end faces the upper side of the upper opening in the post-use storage unit 37.

  Then, by rotating the roller support 45 to bring the second roller 43 to the fixed position, as shown in FIG. 9B, the polishing cloth 14 wound around the first roller 42 is It is sandwiched between the first roller 42 and the second roller 43 and is fixed so as to be immovable. After the setting work of the polishing cloth 14 is completed in this way, the polishing cloth 15 is closed with respect to the feeding belt section 13 so that the polishing is suspended from the upper end to the lower end of the front surface of the guide rail. Cloth 14 will be in the state which opposes the conveyance side moving part of the said conveyance belt 12. FIG. When the second roller 43 is brought to the fixed position, the first roller 42 and the second roller 43 are covered by the cover 47 of the roll support 45 so that fingers can be prevented from entering the rotating part. It has become.

  During the setting operation of the polishing cloth 14, the polishing cloth 14 stored in the main body 31 of the pre-use storage box 30 is pushed by the elastic member 36 and pulled out while maintaining a multilayered state. It is suppressed that 14 is twisted or entangled. Further, resistance is applied to the polishing cloth 14 drawn out by the compression urging of the elastic member 36, so that the excessive polishing cloth 14 can be prevented from being drawn out, and the polishing cloth 14 can be prevented from being pulled out at the portion facing the feeding belt 12. It is possible to suppress 14 from becoming dull. Further, in the embodiment, the polishing cloth 14 accommodated in the main body 31 in a layered state is compressed and urged toward the side away from the opening 30 a from which the polishing cloth 14 is drawn out by the elastic member 36. Therefore, the polishing cloth 14 drawn out from the opening 30a comes into contact with the inner edge of the opening 30a and is given a required resistance, which can also suppress the pulling out of the polishing cloth 14 more than necessary.

  Next, the lifting of the game ball by the lifting and polishing apparatus 10 will be briefly described. When the lifting motor 17 is driven to circulate and move the lifting belt 12, the game ball taken into the inlet at the lower end of the facing portion of the polishing pad 14 and the lifting belt 12 through the inflow guide 19. Is lifted in a state of being sandwiched between the lifting belt 12 and the polishing cloth 14 by moving the lifting belt 12 upward with respect to the stopped polishing cloth 14, and the game The sphere is polished by friction with the polishing pad 14. And it transfers to the opposing part with the said non-abrasive member 18 from the opposing part of the feeding belt 12 and the polishing pad 14, and is further pumped, and is discharged | emitted from the said discharge guide 20 to the said ridge.

  In this game ball lifting process, as the game ball rises, the polishing cloth 14 is also pulled upward in the polishing path of the game ball, but the portion of the polishing cloth 14 facing the lifting belt 12 is also pulled up. Since the first roller 42 and the second roller 43 are pressed against and fixed to the downstream side in the tensile movement direction from the lower end of the polishing pad 14, the polishing cloth 14 does not move upward. However, there is a possibility that the polishing cloth 14 will be rubbed due to friction, but the rugged portion moves from the upper end of the guide rail to the rear side due to friction with the game ball, and is stored before use by its own weight. It is possible to return to the inside from the opening 30 a of the box 30. That is, the doughed polishing cloth 14 is exposed to the outside of the lift polishing apparatus 10, and when a game worker performs a maintenance operation, the finger or tool is hooked to obstruct the operation. It can be prevented in advance.

  Next, the operation in the case where the polishing cloth 14 suspended on the portion facing the lifting belt 12 becomes dirty and the dirty used portion is replaced with an unused portion will be described. When the start switch 51 is pressed, the shutter is actuated to close the inflow port, and a new game ball is taken from the inflow port into the opposing portion (polishing feed path) via the inflow guide 19. It will not be. At this time, the count of the standby time set in the timer 52 is started, and the tension motor 41 is not driven until the count is finished. The game ball that has been placed is lifted and discharged through the discharge guide 20. In addition, when the predetermined time (time when all game balls are discharged) elapses within the waiting time, the driving of the lifting motor 17 is stopped and the circulating movement of the lifting belt 12 is also stopped.

  When the standby time elapses, counting of the driving time set in the timer 52 is started, the tension motor 41 is driven in the forward direction, the first roller 42 rotates in the forward direction, and the polishing pad 14 is rotated. As the second roller 43 that is in pressure contact with each other also rotates, the polishing pad 14 is pulled and moved. That is, the part from the lower guide roller 39 to the tension driving unit 40 is pulled upward, and thereby the used part facing the part opposite to the feeding belt 12 is pulled downward and stored before use. The unused portion of the polishing pad 14 drawn out from the opening 30 a of the box 30 is newly guided to the portion facing the lifting belt 12. Further, the used portion of the polishing cloth 14 is dropped into the space 37a of the post-use storage unit 37 by the weight of the rollers 42 and 43, and is held in the open state in the storage unit 37. It is stored in the rear storage body 56 (see FIGS. 4 and 5). Then, when the driving time has elapsed, the driving of the tension motor 41 is stopped, and the rotation of the first roller 42 is stopped, so that the polishing cloth 14 is not pulled and moved. As a result, the unused portion of the polishing pad 14 is stretched over the entire length of the portion facing the transport belt 12, and the replacement operation is completed.

  As described above, in the embodiment, the used portion of the polishing cloth 14 is dropped into the space 37a of the post-use storage unit 37 by its own weight without being wound in a roll shape, so that the used portion is pulled and moved. There is no need to provide a driving part other than the tension driving part 40, the number of parts is reduced, the configuration is simplified, and the lifting and polishing apparatus 10 can be downsized. Further, when setting the polishing cloth 14, it is only necessary to move the second roller 43 to the open position with respect to the first roller 42, and there is no need for complicated operations such as removing the belt from the pulley as in the prior art. Further, if the polishing cloth 14 is sandwiched between the first roller 42 and the second roller 43, the polishing cloth 14 can be pulled and dropped into the space 37a. In addition, it is not necessary to perform a complicated operation of further attaching the tip of the polishing pad 14 passed between the rollers 42 and 43 to the take-up shaft, and the setting operation can be simplified.

  Further, as shown in FIG. 4, the entrance / exit 37 b of the post-use storage unit 37 is covered with a polishing cloth 14 before being dropped into the space 37 a, and the polishing cloth 14 is opposed to the feeding belt 12. The first and second rollers 42 and 43 are pressed and fixed in a tension state. Therefore, even if the polishing cloth 14 dropped into the space 37a and the post-use storage body 56 in which the polishing cloth 14 is stored are biased to the outside due to its weight, they do not protrude outside from the entrance 37b. There is no obstacle to maintenance work. In addition, since the entrance / exit 37b is covered with the polishing pad 14, there is no need to separately provide a door or the like for opening / closing the entrance / exit 37b, and the number of parts can be reduced and the cost can be reduced. Further, since the entrance / exit 37b is always covered with the polishing pad 14, it is possible to prevent foreign matters other than the polishing cloth from entering the post-use storage body 56 through the entrance / exit 37b.

  When the replacement operation of the used portion and the unused portion of the polishing cloth 14 is repeated, and the sensor 25 is not pressed by the polishing cloth 14 during the operation, the control section stores the pre-use storage box 30. It is determined that the polishing cloth 14 that has been used up is used up, and the operation is stopped by stopping the tension motor 41. At this time, by switching the rotation direction switch 53 to the “normal rotation” side, the tension motor 41 is driven to rotate forward, and the polishing pad 14 remaining on the upstream side in the tensile movement direction from the tension drive unit 40. Can be dropped into the space 37a of the post-use storage unit 37 and stored in the post-use storage body 56. When all the polishing cloths 14 are stored in the storage body 56 after use, the entrance 37b is opened, so that the used polishing cloth 14 is stored only by removing the eyelets 57, 57 from the hooks 59, 59. The used storage body 56 can be easily taken out via the doorway 37b. Further, since the post-use storage body 56 removed from the post-use storage section 37 can be carried to a place where washing (washing) is performed, it can be easily delivered to a cleaning company or the like. In addition, since the polishing cloth 14 stored in the storage body 56 after use is not in a roll state as in the prior art but in an unwound state, washing (washing) is performed while being removed from the storage body 56. This can be done, and the troublesome work of solving the roll state can be saved. Furthermore, since the dirty polishing cloth 14 after use is stored in the storage 56 after use, it is possible to prevent the dirt from adhering to the inside of the storage 37 after use. Furthermore, when carrying the abrasive cloth 14 after use, the dirt does not adhere to clothes or the like.

  Further, since the storage body setting section 60 is provided on the inner front surface where the entrance 37b is not formed in the post-use storage section 37, when the post-use storage body 56 is removed from the post-use storage section 37, or a new use When the rear storage body 56 is stored in the post-use storage section 37, the storage body installation section 60 does not get in the way. In addition, since the container 37 after use was made into a bag in the embodiment, it is easy to carry the polishing cloth 14 after use, and the volume can be reduced by compressing the space portion where the polishing cloth 14 is not contained. For example, it is possible to keep the space for storing in a warehouse or the like small until it is delivered to the cleaning company.

  Here, when the used portion of the polishing cloth 14 is wound and collected in a roll shape, the diameter increases as the amount increases, and the protrusion amount of the lifting polishing apparatus 10 to the rear increases accordingly. Therefore, a large installation space is required because it is necessary to secure the accommodation space (recovery space for the polishing cloth 14 after use). However, in the configuration in which the polishing pad 14 is dropped into the space 37a of the post-use storage unit 37 as in the embodiment, the space 37a is made long and the length of the post-use storage body 56 is set correspondingly long. The amount of protrusion to the rear can be suppressed, and the installation space for the lift polishing apparatus 10 can be reduced.

[Another embodiment of the housing installation section]
FIG. 11 shows another embodiment of the storage body installation portion, and the other components are the same as those in the above-described embodiment. That is, the storage body installation portion 61 of another embodiment includes a U-shaped holding portion 62 that opens to the entrance / exit 37 b side inside the post-use storage portion 37, and L at both ends of the holding portion 62. The character-shaped support portions 63 and 63 are bent, and the support portions 63 and 63 are detachably fixed to the inner front surface of the storage portion 37 after use. When the post-use storage body 56 is attached to the storage body installation portion 61 of another embodiment, the opening edge portion is placed outside with the vicinity of the opening end of the storage body 56 positioned inside the holding portion 62. And is held on the holding portion 62, so that the mouth portion 56a is held open. Even in this case, since there is no hindrance to the post-use storage body 56 on the doorway 37b side, the storage body 56 can be easily put in and out of the post-use storage section 37. The length of the quadrilateral virtual frame A that includes the U-shaped holding portion 62 is set to be slightly longer than the length of the opening edge of the post-use storage body 56, and the opening of the storage body 56 is set. It is preferable to hold the edge in a tensile state.

[Another embodiment of storage box before use]

Yes. In addition, the same code | symbol is attached | subjected and shown to the same member already shown to the said Example.

  That is, in another embodiment, a substantially V-shaped elastic member 36 that expands toward the lid portion side is disposed on the inner surface of the bottom wall 31a of the main body portion 31 and is polished on the elastic member 36. With the cloth 14 folded back and stored in the main body 31, the lid 33 is closed so that the polishing cloth 14 is compressed and urged toward the wall 33 a of the lid 33. It is. Also in this alternative embodiment, since the polishing cloth 14 can be compressed by the elastic member 36 to reduce the volume, many polishing cloths 14 can be stored in the storage box 30 before use.

  Further, since the polishing pad 14 is pushed by the elastic member 36 toward the wall 33a of the lid 33 close to the opening 30a in the pre-use storage box 30, the leading end of the polishing pad 14 is always open. The polishing cloth 14 can be smoothly drawn out from the opening 30a by being positioned close to the portion 30a. Also in another embodiment, a polishing cloth is formed by forming a relief port 31b on the bottom wall 31a of the main body 31 to allow the end edge of each curved portion 36a of the elastic member 36 to protrude outward. You can earn 14 storage.
