Description

  The present invention relates to a guide device capable of smoothly guiding a load with a simple configuration and efficiently moving a carrier.

  Conventionally, in an apparatus for guiding a moving object such as a carrier using a guide rail, a moving body (carrier) provided with a guide roller is brought into contact with a rail provided with a guide portion along a normal moving direction. A device that is allowed to travel is generally used.

  With respect to the guide device that guides and travels the carrier having the guide roller and the traveling device (conveyance device) using the carrier, for example, as known from Patent Document 1, FIG. 31 and FIG. As shown in the above, both sides of the guide rail with the required width are inclined on the top and bottom, and a guide roller having a V-shaped guide groove is applied to both the inclined surfaces so that the guide rail is sandwiched from both the left and right sides. Thus, a carrier configured to guide and travel a carrier having the guide roller is used.

  However, in the above-described conventional guide rail, the guide surface is an inclined surface with a large surface area. To accurately finish the inclined guide surface, high-precision polishing is required, and if it becomes long, the production cost However, there is a problem that it is difficult to obtain a highly accurate product in consideration of economy. Moreover, when the guide roller rolls with both of the inclined surfaces interposed therebetween, the peripheral speed of the V-shaped groove portion of the guide roller that comes into contact with each point of the contact surface due to the rotation of the guide roller is different. There is a drawback that the frictional resistance is increased by rubbing at each part, and the guide surface of the guide rail as well as the guide roller is locally worn to prevent smooth guidance.

  Therefore, in order to solve this problem, a travel guide device described in Patent Document 1 or Patent Document 2 is proposed as a guide device having a simple configuration, improved accuracy, improved workability, and improved durability. ing.

  However, in the travel guide device proposed by Patent Document 1 or 2, guide ridges having a triangular section with a small acute angle are formed on both sides in the width direction of the members constituting the guide rail, and the guide protrusions. A flat surface is formed on both sides of the base of the strip, and the guide roller has a configuration in which an outer peripheral surface thereof is in contact with the flat surface and at the same time a part of the inclined surface of the guide projection is formed. Using a roller with a bearing, smooth the guidance. For this reason, accuracy is still required in the production of the guide rail, and it becomes expensive especially when a curved portion or the like is produced. In addition, when the guide roller is guided along the straight portion of the guide rail, the conventional type is improved. However, since the resistance is also increased in the curved portion, it is necessary to reduce the accuracy so that the vehicle can run. There is a problem such as it occurs.

Further, in addition to the above-described prior art, as is known from Patent Document 3 or Patent Document 4, guides formed by round bars on both sides of a main body member (support member) of the guide rail as a guide portion of the guide rail. The member is sandwiched and supported from above and below so that a part of the member is exposed, and the exposed portion of the guide member serves as a guide portion of the guide roller, and the guide roller has a guide groove that contacts the guide portion of the guide rail. It is set as the structure which uses what was formed in. According to this form, since the guide member is manufactured separately from the support member and the two are combined, the cost can be reduced. There are, however, a structure in which a guide member made of a round bar is incorporated into the support member for a number of minutes, so it is necessary to increase the processing accuracy of the related parts, which is expensive and still a problem to improve the accuracy of the guide part There is a point.

Japanese Patent Laid-Open No. 9-175387 JP-A-10-324237 JP 2003-31828 A Utility Model Registration No. 3146360

  The guide device of the present invention is intended to provide a guide device that can solve the above-mentioned problems and obtain a highly accurate guide structure with a simpler configuration and can be used for multiple purposes. .

In order to achieve the above object, the guide device of the present invention comprises:
A guide device that guides a moving body by combining a guide roller and a guide rail that protrudes from a guide portion that a guide groove of the guide roller contacts,
The guide rail is configured such that a protruding ridge bulges on one side surface at a required height position from a support reference surface, and a curved surface portion excluding the top end portion of the protruding ridge becomes a guide portion of the guide roller, The rail member is supported by the supporting means on the side surface opposite to the guide portion forming surface (first device).

  In the above invention, the guide rail has a shape in which the guide portion of the projecting ridge has an arc-curved surface at an intermediate position in the width direction using a metal plate member having a required width dimension, with one side end surface in the width direction serving as a support reference surface. It is formed by bulging by plastic deformation to be used with the width direction as the height direction (second device).

  In the above device, the guide rail is configured to be held by separately fixing a surface opposite to the ridge forming surface along a holding body so that one end in a height direction maintains a support reference surface. (3rd device).

  In the invention, the guide rail is integrally provided with a support member that forms a mounting seat having a required width on the protruding ridge forming surface side adjacent to the supporting reference surface or on the opposite side of the protruding ridge forming surface. It is good that it is made structure (4th device).

  Still further, the guide rails are arranged in parallel so that the guide portions of the guide rollers are positioned inwardly or outwardly symmetrically at a cross-sectional position at a required interval, and are fixedly fixed to the holding body. (5th device). When the guide portions of the guide roller are directed inward from each other, the holding body is in a positional relationship in which the support portions by the holding body face each other, and when the guide portions of the guide roller are directed outward from each other, It is good to provide in the state which a holding body interposes between guide rails.

  In the above invention, the guide roller has a structure in which a support roller having a fixing means at one end receives a thrust load and a rotatable roller is supported, and the circumferential surface of the roller is substantially in the width direction. A guide groove having a peripheral edge cut in an arc shape within ½ is provided, and the groove surface intermediate portion of the guide groove can be guided in contact with the upper and lower or upper curved surface of the guide rail. (6th device). In addition, it is preferable that this guide roller is used by assembling it so that it becomes a U-shaped groove with two rollers having the above-described structure on the support shaft so as to face the guide groove forming portion.

  Further, in the present invention, the guide rail is formed in a ring shape having a required diameter, and the guide rollers arranged at least at three locations are brought into contact with guide portions formed by ridges formed on the ring guide rail. The turntable is configured by placing either one of a base for supporting the guide rollers or a support member for supporting the ring guide rail (7th device).

  Further, the ring guide rail is a concentric double circle, and the ridge guide portions of the inner and outer ring guide rails are arranged on the opposite sides of the inner and outer sides, corresponding to the guide portions formed by the inner and outer ridges. It is preferable that the plurality of guide rollers be arranged so as to contact each other (eighth device). Such a configuration is effective when the load is large or as a large turntable.

  According to the guide device of the present invention, a metal plate member (rail member) provided with a ridge guide portion serving as a main portion of a guide rail is integrally welded to a support body or a base end portion as a fixed support means. By selectively using any of the support members, the support member can be stably supported in various forms. In the guide device of the present invention, the guide roller is brought into contact with the guide rail, and either the carrier or the moving body attached to the rail member can be guided and moved stably and smoothly. A highly effective device can be obtained.

  In addition, according to this device, a rail member formed of a metal plate material is mainly used. Therefore, a curved rail or a ring rail can be manufactured relatively easily by bending the rail member. By combining the guide rollers, there is an advantage that a conveyance path having a curved portion, a turntable device, and the like can be provided at a low cost.

  Next, an embodiment of a guide device according to the present invention will be described with reference to the drawings.

  A guide device 1 according to the present invention shown in FIG. 1 represents a basic configuration, and a metal plate as a base material is formed by projecting a part of a metal plate having a required dimension in a direction orthogonal to the plate surface over the entire length. One end surface in the width direction of the plate is a reference surface 12 (corresponding to the support reference surface of the present invention), and the rail member 11 is mainly composed of an outer surface of the ridge portion as a guide portion 13 (details will be described later). The guide rail 10 is formed by combining a guide roller 22 having a guide groove 22 formed on the peripheral surface thereof and guiding the guide groove 22 in contact with the guide portion 13 of the guide rail 10.

  First, the guide rail 10 uses, for example, a metal plate having a thickness of about 3 mm as a base material and is formed into a strip shape with a required width dimension, and one side surface in the width direction of the base material is used as a reference surface 12. From the reference surface 12, a ridge bulges on one surface over the entire length at a required height at an intermediate position in the width direction to form a guide portion 13. In use, the guide rail 10 has a rail member 11 which is vertically oriented so that the reference surface 12 faces downward, and a ridge that forms a guide portion 13 is located at a height position of a required dimension from the reference surface 12. Is set as follows. Of course, when the guide roller 20 comes into contact with the guide portion 13 and is guided to move, in principle, the position of the ridge (guide portion 13) is set so that the lower portion of the guide roller 20 is not below the reference surface 12. . The plate thickness dimension of the metal plate used as the rail member 11 of the guide rail 10 is not limited to the above numerical value, and can be set to an arbitrary dimension according to the application. In addition, as a metal plate of the base material, a steel plate or a stainless steel plate (other metal plates may be used if necessary) is used.

  As shown in FIG. 2 and FIG. 3B, the protruding ridge (guide portion 13) in the guide rail 10 is formed to bulge out as a whole, and in detail, from the top end portion 13a to the raised base portion 13b. The surface of the intermediate portion is a guide portion 13 c that is guided by contacting with the guide groove 22 of the guide roller 20. The raised base 13b of the ridge is shaped so that the outer surface of the rail member 11 and the terminal end portion of the ridge formation are small concave curved surfaces that are not broken by an external force. The guide portion 13 is formed in a semicircular shape with a height dimension h that approximates the wall thickness t of the plate material that constitutes the rail member 11. In this way, the thickness of the guide portion 13 is kept substantially constant as a whole, and the guide portion 13 can be bulged by being plastically deformed without reducing the strength.

  The guide rail 10 configured as described above is supported on the back side (side surface without the guide portion 13) by the support body 40 in use. Alternatively, a support means such as attaching a support member to form an integral structure is employed. Therefore, first, an embodiment of the method of supporting and fixing by the former support body 40 will be described with reference to FIG. FIG. 4 (a) shows, for example, wooden frames 41 and 41 (support members) arranged at a required interval (with a relatively wide distance), and stepped portions 42 are provided on opposite sides thereof. The guide rail 10 is supported by applying the reference surface 12 to each step 42. Each guide rail 10 is provided with a mounting hole 14 at a required interval in the longitudinal direction at the base portion between the guide portion 13 and the reference surface 12, and fixed to the frame body 41 by the wood screw 17 through each mounting hole 14. Has been placed upright. With this configuration, the guide rail 10 is fixed to the frame body 41 by the wood screw 17 and is stably fixed by abutting and supporting the reference surface 12 to the mounting step portion 42 of the frame body 41. Retained.

  Further, FIG. 4B shows another embodiment, in which the guide rails 10 and 13 are symmetrically arranged with the guide portions 13 and 13 facing each other on the inner wall surface of the support body 44 formed in a wide groove shape. 10 is provided, mounting screw holes 14a are provided at a plurality of locations at a predetermined interval in the longitudinal direction on the base at a position below the guide portion 13, and the mounting screw holes 14a are provided from the outer surface of the upright portion of the support body 44. The screw 17a is screwed and attached.

  Further, FIG. 4 (c) shows still another embodiment in which both side surfaces 45 'of a block-like support member 45 (corresponding to the holding body of the present invention) having a required width are formed in parallel. The guide rails 10 are symmetrically arranged on both outer side surfaces 45 ′ in such a posture that the guide portion 13 faces outward, and the mounting holes 14 b are arranged at a required interval in the longitudinal direction at a position below the guide portion 13 of the base portion. Are provided at a plurality of locations, and the guide rail 10 is attached by screwing the small screw 17b to the support member 45 from the outside. In this embodiment, when the reference rail 12 of the guide rail 10 matches the lower surface of the support member 45, and the guide rail support member 45 that is unitized with respect to the base or the like is fixed, the upper surface of the base The reference surface 12 of the guide rail 10 is in contact with the load so that the load can be received.

  On the other hand, the guide roller 20 includes, as shown in FIG. 1 and FIG. 3 (a), a support shaft 25 having a threaded portion 25 ′ that can be fixed to a carrier 50 or a stationary body (for example, a base) at one end, A guide groove that is configured to include a roller 21 having a required diameter that is rotatably supported by a support shaft 25, and that is guided by abutting against a guide portion 13 formed by a protruding ridge of the guide rail 10 on the outer peripheral surface of the roller 21. 22 is formed.

  The roller 21 is configured by combining two rollers 21a and 21b of a rolling bearing structure (ball bearing structure) in which a large number of balls are incorporated in the axial direction, and the connecting portion of the roller 21 is connected to the roller 21. A guide groove 22 made of a curved groove is formed at a required depth at the center in the width direction (height direction). As shown in FIG. 3B, the guide groove 22 is equally decentered by a predetermined dimension i on the top and bottom (in the direction of the support axis) on the basis of the joint surface of the rollers 21a and 21b in the figure. An arc concave curved surface drawn with a radius R with a point away from the radius Ra as a base point is defined as one end of the concave curved surface being the maximum outer diameter D of the roller 21a and the other end being the minimum outer diameter D 'of the roller 21a. It is shaped so that it forms a curved groove when the two concave curved surfaces face each other. It is to be noted that the surface of the rail member 11 and the outer peripheral surface of the roller 21 are set so as to be able to move with a gap ta during contact guidance between the guide rail 10 and the guide roller 20.

  For example, as shown in FIG. 4A, the guide roller 20 formed in this way has a guide rail 10, a pair of guide rails 10, 10 that are arranged opposite to each other at a predetermined interval. The support shaft 25 is suspended and fixed at a plurality of locations at predetermined intervals in the moving direction on the base 51 of the carrier 50 that is adapted to move along the screw 10, and screwed into a screw hole 25 a provided at the center of the lower end of the support shaft 25. The lower end portion of the inner ring is fixed with the countersunk bolt 26, and the rollers 21a and 21b are related so that the guide groove 22 comes into contact with the guide portion 13 formed by the ridge of the guide rail 10 facing the guide groove 22. The guide roller 20 is provided so as to be able to travel by being guided by the guide rail 10 (see FIG. 1). The support shaft 25 of the guide roller 20 has a flange portion 25b provided at an intermediate portion thereof in contact with the bottom surface of the base 51 of the carrier 50, and a nut 27 on the screw portion 25 'on the mounting hole 52 provided in the base 51. Are fixed by being screwed together (however, this is not a limitation, and the support shaft 25 can be fixed and held vertically). In this embodiment (FIG. 4 (a)), the base 50 is formed by laminating and fixing a wood plywood 55 on an upper part of a metal plate 54 (for example, a steel plate) having a required thickness, and protects the object to be carried. I am trying.

  In the guide device 1 of the present invention in the transport device configured as described above, the guide rail 10 is fixed to the support member 40 (44, 45) on the back side of the guide rail 10 by screws and the lower reference surface 12 is supported on the support member 40. It is received and held by the stepped portion 42 (bottom surface 44a in the groove) formed in (44). The plurality of guide rollers 20 attached to the carrier 50 are rotatably supported by a support shaft 25 that is fixed to a base 51 and held vertically, and the rollers 21 are formed on the outer peripheral surface. The guide groove 22 is brought into contact with the guide portion 13 formed by a protruding ridge of the guide rail 10, and the carrier 50 is guided along the guide rails 10 and 10 through the plurality of guide rollers 20 at the left and right positions in the traveling direction.

  The load applied to the carrier 50 acts on the left and right guide rails 10 via the guide rollers 20, and the groove surface of the guide groove 22 of the guide roller 20 and the guide portion 13 at the ridge of the guide rail 10. A load acts at the contact point. As described above, the guide rail 13 has a concave curved surface radius R on the inner surface of the guide groove 22 of the guide roller 20 so that the guide rail 13 is an intermediate portion in the curved surface from the top end portion 13a of the protruding ridge to a slightly raised base portion 13b. Is larger than the curved surface radius of the guide portion 13 formed by the ridge, so that the contact relationship between the guide portion 13c of the guide portion 13 and the guide groove 22 concave curved surface of the roller 21 is set to a point contact state. The component of action due to the load acts almost toward the center of the ridge formation (note that the contact position relationship between them is preferably an angle θ = approximately 90 °). Therefore, the roller 21 of each guide roller 20 rolls while making point contact while being stretched against the left and right guide rails 10. Moreover, since the guide groove 22 of the roller 21 in the guide roller 10 moves so as to sandwich the guide portion 13 of the guide rail 10 from above and below, it is smoothly guided without being lifted at the guide position when the carrier 50 travels. Further, the direct load on the guide rail 10 acts on the step receiving surface of the support body by the reference surface 12 of the base portion. The support body (frame body 41) for supporting the guide rail 10 receives the reference surface 12 of the guide rail 10 in a steady manner by forming the level of the stepped portion 42 correctly and constantly, and generates irregular stress. There is no occurrence. Further, as described above, the guide rail 10 is stably supported by screwing and fixing the back surface of the base material along the support.

  In the embodiment shown in FIG. 4 (b), the guide rail 10 is opposed to the groove-shaped support body 44 as the conveying path by making the guide portions 13 face each other on both the left and right inner surfaces in the running direction, respectively. In this manner, the guide rollers 20 provided with the carrier 50 are brought into contact with the guide portions 13 of the guide rail 10 and guided. If it does in this way, it can adopt to moving means, such as an automatic machine, and can be put together compactly.

  Further, as a support and fixing means of the guide rail 10, for example, as shown in FIG. 4C, a block having a required dimension made of wood plywood or aluminum is used as the support 45, and the guide rail 10 is guided along both parallel outer surfaces. If the rails 10 are fixed to the mounting holes 14c provided in the base material using the machine screws 17b and the guide portions 13 are arranged horizontally outward, the guide portions 13 are directed inward as in the above-described embodiment. Unlike the type in which the guide portion 13 is arranged, the guide portion 13 can be used as a type having the outward direction.

  FIG. 5A shows a different guide rail support form. A guide member 13 is formed by providing a support member 15 having a required width at a lower portion of the rail member 11 in the above-described guide rail 10 and a protruding ridge. The support member 15 serves as a mounting seat in which the support member 15 is integrated by welding horizontally to the base material 11 on the side opposite to the forming surface. In this form, the support member 15 (hereinafter referred to as “mounting seat 15”) and the rail member 11 are such that the lower surface 15a of the mounting seat 15 and the reference surface 12 of the guide rail (rail member 11) are flush with each other. Thus, the upper corner portion and the lower surface of the joint portion are integrated by, for example, laser welding. According to this laser welding, since the base metal is melted and joined, the welding bead can be minimized and integrated with high accuracy (see FIG. 5B).

  If such a mounting seat 15 (support member) is welded to the base end of the rail member 11 to form an L-shaped cross section, the guide rail 10A as a whole can be self-supported, and can be fixed and held by fixing the bolt at the mounting seat 15 portion.

  Next, FIG. 6 shows a mode in which the conveyance path makes a U-turn, and the guide rail 10A in the form of the straight conveyance path described in FIG. It is curved. In this type, two parallel guide rails 10A and 10A 'are arranged such that the guide rail 10A (hereinafter referred to as the outer rail 10A) located outside the curved portion is the rail member 11 having the structure described above and the guide portion 13 faces inward. In the guide rail 10A ′ (hereinafter referred to as the inner rail 10A ′) located inside the curved portion, the rail member 11 having the above structure is curved so that the guide portion 13 faces outward. Has been. In the outer rail 10A, a support member 15 formed in an arc shape and having a mounting hole is welded to the outer side of the base end portion of the rail member 11, and in the inner rail 10A ′, the base end portion of the rail member 11 is inside. In this manner, the support member 15 'formed in an arc shape and provided with a mounting hole can be fixed by welding. In the figure, reference numeral 50 denotes a carrier, which is capable of traveling while being guided by the inner rail 10A 'and the outer rail 10A through a plurality of guide rollers 20 provided as described above.

  The outer rail 10A and the inner rail 10A ′ thus configured are arranged concentrically at a predetermined interval, and are respectively used by fixing them to a base or the like with a mounting seat 15 (support member). In this device, when used in a place where a U-turn is made due to the convenience of the conveyance path, the rail member 11 having the guide portion 13 formed on one side as described above is basically curved and supported to the required dimensions and shape. The object can be achieved by welding and forming the members 15, 15 'together. Therefore, in the past, the entire rail was manufactured by cutting it into the required size and shape, but since it can be manufactured by bending and partial welding, the manufacturing cost can be significantly reduced. In addition, about a curved structure, the curved part in a required rotation angle can also be comprised besides a U-turn.

  FIG. 7 shows another embodiment in a U-turn (including a curved portion in a range of an arbitrary rotation angle) of the conveyance path. In this embodiment, support members 15b and 15b 'integrally welded along the curved surface of the rail member 11 to the base end portion of the rail member 11 curved in a semicircular shape are both on the conveyance path configuration side ( The side of the inner rail 10B 'and the outer rail 10B are opposite to the guide portion 13 formed by the ridges), and along the corners of the upper surface of each of the support members 15 and 15' and the rail member 11. Semi-arc-shaped reinforcing washers 16, 16 'are arranged. The support washers 16b and 15b 'together with the reinforcing washers 16 and 16' are fastened to the base with a plurality of bolts, so that the stability of the guide rails (outer rail 10B and inner rail 10B ') is enhanced. . In the figure, reference numeral 20 is a guide roller, and 50 is a carrier.

  In the guide rail having such a structure, as shown in FIG. 7, even when the guide portion 13 made of a protruding ridge is arranged on the outer side of the U-turn portion, the guide rail is attached to the guided carrier 50. In addition, it is possible to perform normal travel guidance in opposition to an influence force that causes the guide rails 10B and 10B 'to tilt inward under the external force applied by the plurality of guide rollers 20.

  FIG. 8 shows a main part of the turntable 30 configured based on the technical idea of the present invention. The turntable 30 is equally placed on a ring rail 31 in which the rail member 11 having the above-described configuration is formed in a ring shape having a required diameter and a circular support board 36, and is placed at a plurality of locations (specifically, three locations). The guide roller 20 has the structure described above, and the guide roller 20 is engaged with the guide portion 13 formed by a ridge provided on the ring rail 31 in the same manner as in the guide device 1 described above. It is a structure that is supported in a freely rotatable manner.

  The ring rail 31 is provided with a support ring 33 having a required width dimension so as to be aligned with the reference surface 12 ′, and a loading board having a required shape is attached to the upper surface through a plurality of attachment holes 34 provided in the support ring 33. (The loading board is not shown).

  The turntable 30 having such a structure is a device that can rotate smoothly with a light overall structure, and the load applied to the ring rail 31 via the loading board is divided into a plurality of (in the embodiment). In this case, it is received by the guide roller 20 (in three places) and can be rotated in a stable state. Further, based on this device, the rail member 11 (see FIG. 5B) formed into a straight line is bent and formed into a circular shape, and then welded at a joint portion to form a ring rail. Since 31 can be manufactured, there is an advantage that the ring portion can be cut from a large material like a conventional turntable and can be provided at a lower cost than a finished product.

  FIG. 9 shows another embodiment of the turntable 30A. This turntable 30A has a configuration in which the ring rails 31A and 31B are provided concentrically and double. In this turntable 30A, the outer periphery of the inner ring rail 31B and the inner periphery of the outer ring rail 31A are welded together at the base by an annular support member 33A so as to keep the inner and outer ring rails 31A and 31B at a predetermined interval. In this way, the ring rails 31A and 31B thus configured are fixed by bolting support members 33A to the upper surface of the base at a plurality of locations. On the other hand, a plurality of guide rollers 20 are attached to the loading board 35 (table) at a plurality of equally divided positions, and the guide grooves 22 of these guide rollers 20 are engaged with the guide portions 13 and 13 of the inner and outer ring rails 31A and 31B. It is the structure which was made to rotate and was supported freely.

  The turntable 30A configured as described above has a configuration in which the ring rails 31A and 31B are arranged in a double manner. Therefore, the turntable 30A can be used for a relatively large load or a large table. Even in this case, the production cost can be reduced because the configuration is simple as described above.

  As for the support structure of the rail member in the two guide rails used for the straight conveyance path or the double-structured turntable, as shown in FIG. 10, the support member 15b (15b) with the required width at the base of the rail member 11 is used. ′) Can be welded and integrated as described above to form a structure located inside the conveyance path.

It is what has been.

  In this embodiment, the guide roller 20A disposed below the movable slider 55 has the same basic configuration as the above-described guide roller 20 (see FIG. 1), but is a roller 21a supported by a support shaft 25a. The roller 21a has a concave curved rolling guide portion 22a that is in contact with only the upper guide surface of the guide portion 13 of the guide rail 10 on the lower peripheral surface of the roller 21a. In other words, in any of the above-described embodiments, the guide roller 20 has the guide groove 22 formed on the peripheral surface, but in this embodiment, the portion corresponding to the guide groove 22 is exactly the same. It has a structure with only the upper half.

  In the case of the guide device 1A having such a configuration, when the slider 55 is engaged with the guide rails 10 and 10 and is movably disposed, the guide rollers 20A are arranged on the guide rail 10 from the upper side with respect to the support structure 60. It is easy to assemble by lowering straight so as to be in contact with the guide portion 13. Of course, when removing the slider 55, it is convenient because it can be easily removed by lifting the slider 55 as it is. In addition, as for the relationship between the guide roller 20A and the guide portion 13, as described above, the intermediate position of the rolling guide portion 22a is brought into contact with the intermediate position of the upper curved surface of the guide portion 13 of the guide rail 10 (FIG. 11 (b)).

  In each of the embodiments described above, the same or similar structures described in the first embodiment and the structures described in the following embodiments are denoted by the same reference numerals and detailed. The explanation is omitted. In addition, it is preferable to add a surface treatment such as hard chrome plating to the guide rail in each of the above-described embodiments in order to improve durability.

  In the guide device of this invention, the fixing means for stably supporting the rail member constituting the guide rail is selected according to the use, and the rail member, which is the main body of the guide rail, plastically processes the plate material, Since it is bent, it can be curved as well as a straight rail, so it can be easily incorporated into the curved or curved part of the U-turn even when it is used in the transport path. Become. And since it can be bent, the guide rail itself can reduce the cost, and the economic effect can be enhanced. Moreover, the diversity as a guide device can be expected. Furthermore, since a ring rail can be formed, it can be provided at a low cost as a turntable.
