Description

  The present invention relates to a pumping cylinder body in which a lifting member circulates by a drive source, and a guide that is installed opposite to an outer peripheral surface on one side around which the lifting member circulates and that can be opened and closed with respect to the pumping cylinder body. The present invention relates to a lifting device that lifts a game medium between the lifting member and the guide rail.

As is well known, a conveying belt type ball polishing and lifting device (lifting device) includes a feeding cylinder body around which an endless conveying belt (lifting member) circulates and an abrasive belt (abrasive member) such as a cloth belt. There are various types of so-called guide rail opening / closing mechanisms, which are configured so as to be openable / closable with respect to the main body of the feed cylinder. In recent years, a technology with excellent convenience has been proposed by developing a conventional guide rail opening / closing mechanism. For example, the technology, commonly known as “guide rail” disclosed in Japanese Patent Application Laid-Open No. 9-28912 proposed by the present applicant, Japanese Patent Application Laid-Open No. 10-102874 and Japanese Patent Application Laid-Open No. 2000-93635 proposed by other than the present applicant. There is a technology called “collective opening and closing mechanism”. As a common advantage of these technologies, there are a plurality of locking portions in a locking mechanism (a locking hook part and a locking projection part) that are a part of the guide rail opening / closing mechanism and lock the guide rail to the lifting cylinder body, Even if it exists, it can be mentioned that only one locking point is acted on and the remaining locking points are also acted on in synchronization. In other words, the guide rail can be opened and closed very easily.
Japanese Patent Laid-Open No. 9-28912 (page 4, FIG. 7) Japanese Patent Laid-Open No. 10-102874 (page 2-3, FIG. 1) JP 2000-93635 A (2nd page, FIG. 4)

  However, there is a problem in the above-described prior art. In the prior art, a connecting member (connecting rod) for connecting a plurality of locking members (locking hook portions) itself moves in the longitudinal direction (vertical direction) (Japanese Patent Laid-Open No. 9-28912), guide rail Disclosed in Japanese Patent Application Laid-Open No. 10-102874, Japanese Patent Application Laid-Open No. 2000-93635, that is, a locus drawn by the connecting member itself (moving area of the connecting member) ) Was relatively large. Therefore, when designing a locking mechanism in this type of guide rail collective opening / closing mechanism, as a space for installing a locking mechanism including a connecting member, it is necessary to secure at least a width that allows the connecting member to move, This was a limitation in designing the entire ball polishing and lifting device. Thus, the locking mechanism in the prior art lacked compactness.

  Further, the locking mechanism of the guide rail collective opening / closing mechanism in the prior art has a plurality of operating points (locations where movement occurs by operating one connecting member) (for example, Japanese Patent Laid-Open No. Hei 10- As shown in Japanese Patent No. 102874, the two locations of the shaft 32, the connecting portion of the connecting pin 46 and the operating rod 48), and the change with time causes problems such as breakage at the operating point and lower functionality. There was a fear. In addition, the decrease in functionality may cause a sense of discomfort with respect to the operability of the connecting member. In addition, the presence of the plurality of action points causes the guide rail collective opening / closing mechanism itself to become complicated or large, and there is a problem that the number of parts and manufacturing man-hours increase.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a lifting device that improves the functionality by reducing the size of the guide rail batch opening / closing mechanism.

  In order to achieve the above-described object, in the invention according to claim 1, the pumping cylinder main body around which the pumping member circulates by the driving source and the outer peripheral surface on one side around which the pumping member circulates are installed. And a guide rail that is openable and closable with respect to the lifting cylinder main body, and the lifting device that lifts a game medium between the lifting member and the guide rail. A locking mechanism provided on one side of the lifting device and for locking the guide rail in a closed state with respect to the lifting cylinder body; and provided on the other side of the lifting device and the guide A guide rail opening / closing mechanism configured to pivotally support the rail with respect to the lifting cylinder main body so as to be openable and closable, and the locking mechanism includes the lifting cylinder main body or the guide rail. And the lifting device A connecting member that is rotatable about an axis substantially parallel to the longitudinal direction, a plurality of locking members provided at predetermined intervals on the connecting member, and the other lifting member not provided with the connecting member. And a locking member receiving portion that is provided on either the feed tube main body or the guide rail and that locks the plurality of locking members.

  In the invention according to claim 2, in the state where the guide rail is locked in a closed state with respect to the lifting cylinder body, a gap formed between the guide rail and the lifting cylinder body is formed. A restriction member for restricting the maximum dimension is provided on the locking member.

  In the invention according to claim 3, in the state where the guide rail is locked in the closed state with respect to the lifting cylinder main body, a gap formed between the guide rail and the lifting cylinder main body is provided. A scale for measuring is provided at a predetermined position of the locking member.

  Moreover, in the invention which concerns on Claim 4, in the state which the said guide rail was latched in the closed state with respect to the said feeding cylinder main body, the latching of the said latching member with respect to the said latching member receiving part is cancelled | released. A locking mechanism is provided for prohibiting the locking mechanism, and the locking mechanism is configured so that the locking member is in operation when the lifting device is in operation or when a game medium exists between the lifting member and the guide rail. It is prohibited to release the locking of the locking member with respect to the receiving portion.

  In the invention according to claim 1, in the guide rail opening / closing mechanism, for example, by using one locking member to rotate the coupling member, all the locking members provided at a plurality of locations of the coupling member are Since it is possible to perform a batch operation, it is possible to simultaneously lock and release a plurality of locking members with respect to the locking member receiving portion, as in the conventional guide rail batch opening / closing mechanism, which is very convenient. Is good.

  In addition, the connecting member provided with the plurality of locking members rotates (rotates) as the center of rotation of the plurality of locking members (axis substantially parallel to the longitudinal direction of the lifting device). Therefore, there is no need to secure a moving space for the connecting member as in the prior art, so there are fewer constraints and effective in the design stage of the lifting device including the guide rail opening / closing mechanism (guide rail collective opening / closing mechanism). It is. Further, the guide rail opening / closing mechanism can be made compact. In addition, the structure in which the connecting member itself rotates (spins) is, for example, easy to design and accommodates the connecting member itself in the guide rail or the lifting cylinder main body, and has excellent design characteristics. An opening / closing mechanism can be realized.

  Further, in the prior art, there are at least two action points at only one locking point, and at least the number of locking points x two action points in the entire locking point. As a result, the large number of action points caused the problems described in the section of the problem. However, by configuring as in the present invention, the action points are less than in the prior art ( Because it does not exist between the locking member and the connecting member), the problem as described in the section of the problem, that is, the problem that the damage or functionality deteriorates with the passage of time is less likely to occur. Can be said to have improved. Furthermore, it can be said that the operability of the guide rail opening / closing mechanism is also excellent. Further, the structural feature that the number of points of action is less than that of the prior art has the effect of simplifying the locking mechanism itself, reducing the number of parts and manufacturing steps, and leading to cost reduction.

  Further, in the invention according to claim 2, even when the situation that the holding force of the game medium by the guide rail and the lifting cylinder main body is reduced and the game medium is difficult to be lifted occurs, the regulating member is By operating and adjusting the gap formed between the guide rail and the lifting cylinder main body to be reduced, the holding force of the gaming medium between the guide rail and the lifting cylinder main body is increased. Can be lifted reliably.

  Moreover, in the invention which concerns on Claim 3, when adjusting the dimension of the clearance gap formed between a guide rail and a feeding cylinder main body using a control member, the scale provided in the predetermined location of the latching member Therefore, it is possible to easily adjust the overall size of the gap formed between the guide rail and the feed cylinder main body. it can.

  In the invention according to claim 4, the guide rail is prevented from being accidentally opened during operation of the lifting device or when a game medium exists between the lifting cylinder body and the guide rail. Therefore, during operation of the lifting device, the lifting device does not stop functioning due to the opening of the guide rail. Further, the guide rail is opened in a state where the game medium remains in the lifting device, and the game medium remaining in the lifting device is not scattered.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 5 with reference to the drawings.

Further, a connecting member 25 including a locking member 24 for locking the guide rail 5 in a closed state with respect to the lifting cylinder body 3 is provided on the other side surface of the lifting cylinder body 3. Yes. The locking member 24 and the connecting member 25 will be described in detail later.

  The guide rail 5 is mainly composed of a guide rail base 20 that forms the base of the guide rail 5, and a guide rail member 30 in which a plurality of ball paths 31 that are pachinko ball feeding paths are formed. As shown in FIG. 4, the guide rail base 20 has a substantially U-shaped cross section as shown in FIG. 4 so that the guide rail member 30 is attached to the inside of the guide rail base 20. Cloth belt insertion portions 36 into which the side end surfaces of the cloth belt are inserted are formed on both inner sides (the cloth belt is omitted in the figure).

  The guide rail member 30 is made of urethane, and the engaging portions 32 provided at both ends of the guide rail member 30 are engaged with the protrusions 42 of the guide rail base body 20 to restrict the moving range, and the guide rail member 30 is guided. A plurality of springs 35 mounted on the back side of the rail member 30 (on the side opposite to the lifting cylinder body 3) are configured to apply pressure to the pachinko balls that move (rise) the ball passage 31. Further, on the back side of the guide rail member 30, a spring accommodating portion 34 for accommodating one end of the spring 35 and guiding expansion and contraction, and the deformation of the guide rail member 30 are suppressed at the same height as the spring accommodating portion 34. For this reason, a rail support member 33 for regulating the moving range is formed. Further, in the vicinity of the upper end portion of the guide rail member 30, a sensor 19 for detecting a pachinko ball present in the ball polishing and lifting device 1 is attached.

  Further, as shown in FIG. 2, the guide rail 5 has a cloth belt fixing / locking member 22 for locking one end of the cloth belt on its back side and a cloth belt tension locking for pulling and locking the other end of the cloth belt. A member (not shown) is attached, and a cloth belt roller 21 is provided at the upper and lower ends of the member to guide the cloth belt back (the cloth belt roller 21 at the lower end is not shown). Thus, the cloth belt locked to the cloth belt fixing / locking member 22 passes from the cloth belt roller 21 at the lower end of the guide rail 5 through the cloth belt insertion portion 36 formed in the guide rail base body 20, and the cloth belt at the upper end. It is stretched around the roller 21 and is tension-locked to the cloth belt tension-locking member.

  Further, on the side surface of the guide rail 5, when the guide rail 5 is locked in a closed state with respect to the lifting cylinder body 3, a locking member receiving portion 26 to which the locking member 24 is locked is engaged. It is provided so as to correspond to each stop member 24. The locking member receiving portion 26 will be described in detail later. A locking mechanism 28 is configured by the locking member 24, the connecting member 25, and the locking member receiving portion 26 described above, and a guide rail opening / closing mechanism 29 is configured by the support hinge (opening / closing shaft support mechanism) 27 and the locking mechanism 28. Is constituted.

  Thus, the guide rail 5 is closed with the conveying belt 6 and the cloth belt attached as described above, and the locking member 24 is locked to the locking member receiving portion 26 so that the guide rail 5 is attached to the lifting cylinder body 3. After mounting, the pachinko ball fitted into the ball path 31 of the guide rail base body 20 through the cloth belt rises while the conveyor belt 6 is wiped off by moving the conveyor belt 6 around. .

  At the end of business, cloth belt replacement work is performed almost every day. The cloth belt replacement work is performed by pulling the cloth belt located above the cloth belt tension locking member in a state where the cloth belt can move by loosening the cloth belt fixing locking member 22 and the cloth belt tension locking member. The cloth belt is positioned so that the unused surface faces the conveyance belt 6, and then the cloth belt fixing and locking member 22 and the cloth belt tension locking member are tightened to lock the cloth belt. Thus, the preparation for the next day's polishing is completed. The cloth belt has a length of about 7 times the length of the guide rail 5, and the cloth belt for the length of the guide rail 5 is replaced by the replacement work. Can be used for a week. In this way, when the replacement work is repeated for about one week and the fabric belt is used up, the replacement operation of the fabric belt is performed. In the replacement work, first, the cloth belt fixing and locking member 22 and the cloth belt tension locking member are loosened, and the used cloth belt is extracted. Next, after an unused new cloth belt is passed over the cloth belt fixing and locking member 22, the upper and lower ends of the guide rail 5, and the cloth belt tension and locking member, the cloth belt fixing and locking member 22 and the cloth belt tension and locking are used. The cloth belt replacement operation is completed by fastening the member and locking the cloth belt.

  The cloth belt replacement operation described above can be performed with the guide rail 5 opened from the feeding cylinder body 3 or with the guide rail 5 being closed, but can be replaced with an unused new cloth belt. In the case of the replacement work to be performed, it is necessary to carry out the guide rail 5 in a state in which it is opened from the lifting cylinder body 3.

  Next, the locking mechanism 28 constituting the main part of the present embodiment will be described. As described above, the locking mechanism 28 includes the locking member 24 and the connecting member 25 provided on the lifting cylinder body 3 side, and the locking member receiving portion 26 provided on the guide rail 5.

  First, the locking member 24 and the connecting member 25 provided on the lifting cylinder body 3 side will be described. As shown in FIG. 1, the locking member 24 has a cylindrical shape, and is joined in a direction perpendicular to the connecting member 25 that is also formed in a cylindrical shape. Further, a plurality of the locking members 24 are joined to the connecting member 25 at a predetermined interval, and the plurality of locking members 24 are 0 ° to each other on the circumference of the connecting member 25. The angle is made. That is, the plurality of locking members 24 are parallel to each other and joined to the connecting member 25 from the same direction. With such a configuration, the plurality of locking members 24 are connected by the connecting member 25. The surface of the locking member 24 is threaded, and a nut as a regulating member 23 is screwed onto the thread. Further, the guide rail 5 is closed on a part of the surface of the locking member 24 when the locking member 24 is locked to the locking member receiving portion 26 as shown in FIG. A scale 53 is provided on the surface of the locking member 24 at a position corresponding to the gap to measure the gap formed between the main body 3 and the lifting cylinder body 3.

  The locking member 24 and the connecting member 25 configured as described above are mounted on the side surface opposite to the side to which the support hinge 27 of the lifting cylinder body 3 is attached. Specifically, it is housed in a connecting member housing groove 54 formed on the side surface of the lifting cylinder body 3. The connecting member receiving groove 54 is formed in a vertically long and concave shape, and an insertion hole 49 is formed on the inner lower surface thereof. The insertion hole 49 is recessed in a hemispherical shape. By inserting the hemispherical lower end of the connecting member 25, the connecting member 25 is received in the connecting member receiving groove 54. Further, the coupling member housing groove 43 accommodates the coupling member 25 when the coupling member 25 is accommodated and the locking member 24 is rotated to the guide rail 5 side. It communicates with the groove 54 and is formed on the side surface of the lifting cylinder body 3. The insertion hole 49 described above serves as a bearing when the connecting member 25 rotates (rotates), and serves as a pivot point for rotation.

  Further, a connecting member cover 45 for covering the connecting member 25 accommodated in the connecting member accommodating groove 54 is attached to the side of the connecting member accommodating groove 54 on the discharge flange 41 side so as to be opened and closed via a hinge 46. It has been. On the surface of the connecting member cover 45 on the side of the connecting member receiving groove 54, a locking piece 47 is provided so as to be locked in a locking hole 44 described later when the connecting member cover 45 is closed. Further, an operation piece 48 for opening and closing the connecting member cover 45 is provided on the surface opposite to the surface on which the locking piece 47 is provided. As shown in FIG. 1, the connecting member cover 45 prevents the engaging member 24 from interfering with the connecting member cover 45 when the engaging member 24 is rotated to the lifting cylinder body 3 side. Is formed by dividing. The division position of the connecting member cover 45 corresponds to the position where the locking member accommodation groove 43 is formed.

  Further, a locking hole 44 is formed on the side of the connecting member receiving groove 54 on the guide rail 5 side to lock the locking piece 47 of the connecting member cover 45 when the connecting member cover 45 is closed. Yes.

  Further, as shown in FIG. 2, a locking mechanism for prohibiting the release of the locking of the locking member 24 with respect to the locking member receiving portion 26 is provided at one position of the locking member receiving groove 43 as shown in FIG. Is provided. This locking mechanism is configured by a locking device 50 provided below the locking member receiving groove 43 and a locking portion 52 provided above the locking member receiving groove 43. This locking mechanism will be described in detail later. The locking mechanism in the present embodiment is provided above and below the lowermost locking member receiving groove 43 among the plurality of locking member receiving grooves 43, but the locking mechanism positioned at the lowermost position is provided. The engaging member receiving groove 43 is not limited to the member receiving groove 43. Moreover, it is not restricted to what is provided in one place, You may be provided in multiple places.

  Next, the locking member receiving portion 26 provided in the guide rail 5 will be described. As described above, the locking member receiving portion 26 to which the locking member 24 is locked when the guide rail 5 is locked on the side surface of the guide rail 5 in a closed state with respect to the feed cylinder main body 3. Is provided. As shown in FIGS. 1 and 2, the locking member receiving portion 26 has an opening 37 that receives the locking member 24, and a holding portion 39 that holds and holds the received locking member 24. It is formed by bending a metal plate so that its cross-sectional shape is substantially Ω-shaped. The locking member receiving portion 26 is fixed by the holding portion 39 being fitted into a mounting portion 55 formed in a concave shape on the side of the guide rail 5.

  Thus, the cloth belt and the conveyor belt 6 are attached to the guide rail 5 and the feed cylinder body 3 configured as described above, respectively, and the guide rail 5 is closed. Then, as shown in FIG. 3, the locking member 24 is rotated toward the guide rail 5 with the connecting member 25 as the rotation center. At this time, all the locking members 24 provided on the connecting member 25 are simultaneously rotated only by rotating one locking member, and the locking member receiving portions 26 corresponding to the respective locking members 24 are rotated. It is locked to. The locking of the locking member 24 to the locking member receiving portion 26 is performed by the holding member 39 being held and held by the holding portion 39 after the locking member 24 is received by the opening 37 of the locking member receiving portion 26. . Note that, as described above, the surface of the locking member 24 is threaded, but this thread reaches the locking position when the locking member 24 is locked to the locking member receiving portion 26. It has been subjected. For this reason, the holding part 39 of the locking member receiving part 26 clamps the thread of the locking member 24, and the locking member 24 can be clamped more firmly.

  Then, when the locking member 24 is locked by the locking member receiving portion 26, the guide rail 5 is held against the feeding cylinder body 3 in a closed state. At this time, a gap is formed between the guide rail 5 and the lifting cylinder body 3 as shown in FIG. 3, and the maximum dimension of the gap can be regulated by the regulating member 23. Specifically, when the guide rail 5 is closed, the guide rail 5 tries to open due to the reaction force of the conveyor belt 6 or the cloth belt, but the regulating member 23 is turned in the direction of the arrow (clockwise) in FIG. By fixing the guide rail 5 at a predetermined position, the force to open the guide rail 5 is suppressed at that position, and the maximum dimension of the gap formed between the guide rail 5 and the lifting cylinder body 3 is controlled by the restriction member 23. It can be restricted to a fixed position. As a result, even when a situation in which the pachinko ball (game medium) pinching force between the guide rail 5 and the lifting cylinder body 3 is reduced and it is difficult to lift the pachinko ball, the regulating member 23 is operated. Then, by adjusting the direction in which the gap formed between the guide rail 5 and the lifting cylinder body 3 is reduced, the clamping force of the pachinko balls by the guide rail 5 and the lifting cylinder body 3 is increased. Pachinko balls can be lifted reliably.

  Further, when the guide rail 5 is closed, the scale 53 of the locking member 24 is positioned so as to straddle the gap formed between the guide rail 5 and the lifting cylinder body 3 as shown in FIG. It becomes. For this reason, the dimension of the gap formed between the guide rail 5 and the feed cylinder body 3 can be measured by the scale 53 of the locking member 24. Thereby, when adjusting the dimension of the clearance gap formed between the guide rail 5 and the feeding cylinder main body 3 using the regulating member 23, the scale 53 provided at a predetermined position of the locking member 24 is used as a reference. Since each of the plurality of locking mechanisms 28 can be adjusted while being compared, the overall size of the gap formed between the guide rail 5 and the lifting cylinder body 3 can be easily adjusted appropriately. it can.

  Further, as described above, the engagement with respect to the engagement member receiving portion 26 is performed above and below one location of the engagement member receiving groove 43 in a state where the guide rail 5 is engaged with the lifting cylinder body 3 in a closed state. A lock mechanism for prohibiting the release of the locking of the stop member 24 is provided. This locking mechanism is composed of at least a locking device 50, a locking member 51, and a locking portion 52, which will be described later, and is in operation of the ball polishing lifting device 1 or between the guide rail 5 and the lifting cylinder body 3. This is to prevent the guide rail 5 from being accidentally opened when a pachinko ball is present. Whether the pachinko ball is present between the guide rail 5 and the lifting cylinder body 3 is determined by the sensor 19 attached to the downstream side (upper side) of the guide rail member 30 of the guide rail 5 described above. This is performed depending on whether a pachinko ball is detected. Further, whether or not the ball polishing and lifting device 1 is in operation is determined using ON / OFF of a power switch (not shown) that operates a motor built in the lower roller 4. When the ball polishing and lifting apparatus 1 is in operation or when a pachinko ball is detected by the sensor 19, the lock mechanism is activated so that the guide rail 5 is not opened.

  Specifically, when the ball polishing and lifting device 1 is not operating with the guide rail 5 closed, and there is no pachinko ball between the guide rail 5 and the lifting cylinder body 3 Since the locking mechanism is in the state shown in FIG. 5A, the locking member 24 can be released from the locking member receiving portion 26 and the guide rail 5 can be opened.

  On the other hand, when the ball polishing and lifting device 1 is in operation with the guide rail 5 closed, or there is a pachinko ball between the guide rail 5 and the lifting cylinder body 3, the sensor 19 causes the pachinko ball to move. 5B, the locking member 51 protrudes from the locking device 50 and is locked to the locking portion 52, and the locking member 24 is locked to the locking member receiving portion 26, as shown in FIG. Therefore, the guide rail 5 cannot be released. This prevents the guide rail 5 from being accidentally opened during operation of the ball polishing and lifting device 1 or when a pachinko ball is present between the guide rail 5 and the lifting cylinder body 3. Therefore, during the operation of the ball polishing and lifting device 1, the ball polishing and lifting device 1 does not function due to the opening of the guide rail 5. Moreover, the guide rail 5 is opened in a state where the pachinko balls remain in the ball polishing and lifting device 1, and the pachinko balls remaining in the ball polishing and lifting device 1 are not scattered.

  In addition, even when a pachinko ball is present between the guide rail 5 and the lifting cylinder body 3, there may be provided a release means for forcibly releasing the locked state of the locking member 24 by the locking device. There is an effect that it can be quickly performed when the pachinko ball between the guide rail 5 and the lifting cylinder body 3 is forcibly extracted. However, when the ball polishing and lifting apparatus 1 is in operation, the release means for forcibly releasing the locked state of the locking member 24 by the lock device does not function even if the above-described release means is used. More preferably.

  In the above-described embodiment, the locking member receiving portion 26 is provided on the guide rail 5 side, and the locking member 24 and the connecting member 25 are provided on the feeding cylinder main body 3 side.

However, as long as the technical idea of the present invention is not deviated, the technical idea of the present invention can be easily applied to other types of feeding devices. For example, “a guide that can be opened and closed with respect to the bucket that is installed facing the outer peripheral surface on one side where the bucket circulates (ascends) the bucket cylinder as the lifting member circulates by the driving source. Rails, and a so-called bucket-type lifting device or the like that lifts a pachinko ball as a game medium between the bucket and the guide rail.

  Further, in the above-described embodiment, the game medium of the lifting device is shown to be lifted from the lower side to the upper side. However, as long as it does not depart from the technical idea of the present invention, it is lifted in the other direction. The technical idea of the present invention can be easily applied to those that do. For example, horizontal lifting or obliquely upward lifting. Further, in the above-described embodiment, the lifting device is related to a pachinko ball, but the technical idea of the present invention is similarly applied to a lifting device related to other game media (for example, medals). Is easy.

  As described above, the guide rail opening / closing mechanism 29 between the guide rail 5 and the lifting cylinder body 3 of the ball polishing lifting device 1 according to the present embodiment has been described. However, according to the present embodiment, the lifting is performed by the motor as the drive source. A lifting cylinder main body 3 around which the conveyor belt 6 as a member circulates, and a guide rail that is installed opposite to the outer peripheral surface on one side around which the conveyor belt 6 circulates (rises) and that can be opened and closed with respect to the conveyor belt 6 5, and a ball polishing and lifting device 1 as a lifting device that lifts a pachinko ball as a game medium between the conveyor belt 6 and the guide rail 5. A locking mechanism 28 which is provided on one side of the ball polishing and lifting device 1 and locks the guide rail 5 to the lifting cylinder body 3 in a closed state, and the ball polishing and lifting device. Provided on the other side of 1 and A guide rail opening / closing mechanism 29 including an opening / closing pivot support mechanism for pivotally supporting the guide rail 5 with respect to the lifting cylinder body 3 so as to be openable / closable is provided. Is a connecting member 25 that is provided on either the lifting cylinder main body 3 or the guide rail 5 and is rotatable about an axis substantially parallel to the longitudinal direction of the ball polishing lifting device 1; A plurality of locking members 24 provided at a predetermined interval on the connecting member 25, and the other of the feeding cylinder main body 3 or the guide rail 5 on which the connecting member 25 is not provided, and It is characterized by comprising a locking member receiving portion 26 to which a plurality of locking members 24 are locked.

  With this configuration, in the guide rail opening / closing mechanism 29, for example, by rotating the connecting member 25 using one locking member 24, all the engagement members provided at a plurality of locations of the connecting member 25 are provided. Since the stop member 24 can be collectively operated, similarly to the conventional guide rail batch opening / closing mechanism, the plurality of locking members 24 can be simultaneously locked and unlocked with respect to the locking member receiving portions 26. Can be very convenient.

  Further, the connecting member 25 provided with the plurality of locking members 24 serves as a center of rotation of the plurality of locking members 24 (an axis substantially parallel to the longitudinal direction of the ball polishing and lifting device 1). Rotating (spinning), there is no need to secure a moving space for the connecting member 25 as in the prior art, so the ball polishing and lifting device 1 including the guide rail opening / closing mechanism 29 (guide rail collective opening / closing mechanism) In the design stage, there are fewer constraints and it is effective. Further, the guide rail opening / closing mechanism 29 can be made compact. In addition, the structure in which the connecting member 25 itself rotates (spins) is designed so that, for example, the connecting member 25 itself is stored in the guide rail 5 (in the guide rail base body 20) or in the lifting cylinder body 3. It becomes easy, and it becomes possible to realize the guide rail opening / closing mechanism 29 excellent in design.

  Further, in the prior art, there are at least two action points at only one locking point, and at least the number of locking points x two action points in the entire locking point. Therefore, the large number of action points caused the problems described in the section of the problem, but by configuring as in this embodiment, the action points are less than in the prior art. (Because it does not exist between the locking member 24 and the connecting member 25), the problem described in the section of the problem, that is, the problem that the damage and the functionality are lowered with the lapse of time is less likely to occur. It can be said that the functionality has improved. Furthermore, it can be said that the operability of the guide rail opening / closing mechanism 29 is also excellent. Further, the structural feature that the number of operating points is smaller than that of the prior art has the effect that the locking mechanism 28 itself can be simplified, the number of parts and the number of manufacturing steps can be reduced, and the cost can be reduced.

  In the present embodiment, the gap formed between the guide rail 5 and the lifting cylinder body 3 in a state where the guide rail 5 is locked to the lifting cylinder body 3 in a closed state. The locking member 24 is provided with a restricting member 23 for restricting the maximum dimension.

  By configuring in this way, even if the situation where the pachinko ball clamping force by the guide rail 5 and the lifting cylinder main body 3 is reduced and the pachinko ball is difficult to be lifted occurs, the regulating member 23 is provided. By operating and adjusting the gap formed between the guide rail 5 and the lifting cylinder body 3 to be small, the pinching force of the pachinko balls between the guide rail 5 and the lifting cylinder body 3 is increased. The pachinko balls can be lifted reliably.

  In the present embodiment, the gap formed between the guide rail 5 and the lifting cylinder body 3 in a state where the guide rail 5 is locked to the lifting cylinder body 3 in a closed state. A scale 53 is provided at a predetermined position (for example, a position corresponding to the gap) of the locking member 24.

  With this configuration, when the size of the gap formed between the guide rail 5 and the lifting cylinder body 3 is adjusted using the restriction member 23, the restriction member 23 is provided at a predetermined position of the locking member 24. Since each of the plurality of locking mechanisms 28 can be adjusted while being compared with the scale 53 as a reference, the entire size of the gap formed between the guide rail 5 and the feeding cylinder body 3 can be easily adjusted. Can be adjusted.

  In the present embodiment, in the state where the guide rail 5 is locked to the lifting cylinder body 3 in a closed state, the locking member 24 is unlocked from the locking member receiving portion 26. A lock mechanism (lock device 50, lock member, locking portion 52, etc.) for prohibiting is provided, and the lock mechanism is operated during the operation of the ball polisher 1 or the conveyor belt 6 and the guide rail 5. When a pachinko ball is present between them, release of the locking of the locking member 24 with respect to the locking member receiving portion 26 is prohibited.

  With this configuration, the guide rail 5 is accidentally opened when the ball polishing and lifting apparatus 1 is in operation or when a pachinko ball is present between the lifting cylinder body 3 and the guide rail 5. Since this can be prevented, during the operation of the ball polishing and lifting device 1, the ball polishing and lifting device 1 does not function due to the opening of the guide rail 5. Moreover, the guide rail 5 is opened in a state where the pachinko balls remain in the ball polishing and lifting device 1, and the pachinko balls remaining in the ball polishing and lifting device 1 are not scattered.

  In this embodiment, even when a pachinko ball is present between the guide rail 5 and the lifting cylinder body 3, the locking member 24 is forcibly released from the locked state. A release means is provided.

  By configuring in this way, there is an effect that it can be performed quickly when the pachinko ball between the guide rail 5 and the lifting cylinder body 3 is forcibly extracted.
