Description

  The present invention relates to a guide device.

The term “slide” is generally used in the machine field as a sliding guide in a linear direction or in a direction with a two-dimensional spread, but the rolling guide mechanism in the drawer of furniture and the vehicle seat is a component of the slide rail. In the following description, the word “slide” is used as having a broad meaning including a rolling guide in a linear direction or a direction having a two-dimensional spread.

The guide device is an indispensable device mainly for controlling the sliding motion of a vehicle or machine. Usually, the guide device consists of a fixed side portion and a motion side portion. For example, when a railway vehicle is considered as an application of a kind of guide device, a rail placed on the ground corresponds to the fixed side portion, and the vehicle can run freely. The wheel which supports is used as a movement side part, and both are comprised, and a guide apparatus is comprised. Various types of guide devices are proposed, such as those that can withstand high loads depending on the purpose of use, those that can obtain high-precision movement trajectories, and those that can perform high-speed sliding movements. Most guide devices have a straight line or a curve close to a straight line.

As a guide device that makes the direction of the slide motion a straight line or a curve close to a straight line, a guide device in a railway vehicle using a combination of a rail and wheels described above is typical. This type of guide device is not suitable for a guide that greatly changes the direction of motion because the direction in which a load can be received is limited to the direction in which gravity acts and the curvature of a rail that can be laid is limited. For this reason, in addition to the wheel that receives the load, a wheel that sandwiches the side of the rail can be added to make it possible to guide a curved locus with a sharp curve, but the direction in which the straight portion and the curved portion are combined It is unsuitable for use as a guide device for a mechanical device that desires a highly accurate motion trajectory. In addition, there are various types of guide devices in which the wheel is replaced with a sliding portion. However, these guide devices tend to cause problems in lubrication and cooling, and if the lubrication and cooling are not properly performed, the sliding portion Therefore, it is not suitable for a guide device having a high movement speed or a long movement distance.

  In order to eliminate the above inconvenience, for example, as in the technique described in Japanese Utility Model Publication No. 5-44906 of Patent Document 1, the outer periphery of the guide roller is formed on the inner surface of the guide groove having a substantially U-shaped cross section. A guide device of a type in which a surface rolls in contact has been proposed. Since the guide device causes the guide roller to roll in contact with the inner surface of the guide groove having a substantially U-shaped cross section, the direction of travel of the guide roller is also bent where the guide groove is bent, and the mounted loading platform is It is possible to guide along a route in which straight lines and curves are mixed.

However, in the structure of the guide device proposed in Patent Document 1, the outer peripheral portion of the guide roller at a point on the contact region of the guide groove is in contact with the inner surface of the guide groove, so that the relative speed is zero. The relative speed at the point of the outer periphery of the guide roller that is 180 degrees away from the point that is in contact is twice the speed at which the center of the guide roller moves. Therefore, in order to smoothly roll the guide roller placed in the guide groove, it is possible to avoid contact between the guide roller and the inner surface of the guide groove on the opposite side of the guide roller contact point of the guide groove. An appropriate distance gap is required. If this gap is too small, the guide roller will slide instead of rolling, and rubbing while contacting both sides of the guide groove, so that the guide groove and the guide roller are worn and the accuracy of the guide device is reduced. Stability will be impaired. In addition, even if the gap between the inner surface of the guide groove and the guide roller is appropriate, the accuracy and stability of the guide device cannot be improved beyond a certain level due to the existence of the gap itself. The gap between the inner surface of the guide groove and the guide roller becomes a main source of noise and vibration.

  In addition, the linear guide device described in Japanese Patent Application Laid-Open No. 11-37154 of Patent Document 2, the linear motion device described in Japanese Patent Application Laid-Open No. 2000-320641 of Patent Document 3, and Japanese Patent Application Laid-Open Publication No. 2004 of Patent Document 4. Techniques for manufacturing a motion guide device, a ball screw, and a ball rolling groove described in Japanese Patent No. 162748 have also been proposed. The market also includes high-accuracy linear motion guide devices that incorporate moving side parts supported via rollers and balls on rails with a special cross-sectional shape, and arc guide devices that guide curved sections with specific curvature. Have been supplied. However, all of the above-mentioned guide devices cannot mix a linear rail and a curved rail, and the arc guide device can be used only at a curved portion of the intrinsic curvature.

  When it is desired to obtain a highly accurate slide motion trajectory using a guide device, it is often necessary not only to control the slide motion but also to transmit electric power and electrical signals. It is required to match the trajectory with the transmission trajectory of electric power or electric signal. However, conventionally, the guide device and the power and electrical signal transmission device are separately used, and it has been difficult to perfectly match the motion trajectory of the guide device and the motion trajectory of the power and electrical signal transmission device. . For this reason, in many cases, a mechanism such as a cord reel device or a pantograph to be added in order to eliminate the wrinkles between the movement trajectories of both is necessary, which causes the size of the device or device to increase.

In addition, when it is desired to obtain a highly accurate slide motion trajectory using the guide device, it is often necessary to transmit not only the slide motion but also power. In the above case, it is required to match the movement trajectory with the power transmission trajectory, which is also supplied to the market as a product. However, the above-mentioned products supplied to the market are limited to small-sized guide devices, and are dedicated to circular motion with a fixed radius and a linear guide device provided with a power transmission device in a position parallel to the guide device. Except for the guide device, it can be said that there is virtually no highly accurate guide device in which a power transmission mechanism is provided in a guide device that can obtain a motion locus in which linear motion and curved motion are combined.

FIG. 1 is a perspective view showing an outline of the guide device of the present invention in which the outer peripheral surface of a guide roller is brought into contact rolling with the opposing inner surface of a guide groove having a substantially U-shaped cross section. In general, a guide groove having a long dimension is cut off at the front and rear, and only a main part is illustrated. Reference numeral 1 denotes a guide device according to the present invention, 2 denotes a guide groove, 3 denotes an inner surface of the guide groove, and 4 denotes a guide roller. Is the outer peripheral surface of the guide roller. Reference numeral 6 denotes a contact area on the inner surface of a guide groove 3 described later, 7 denotes a non-contact area, and 8 denotes a guide roller shaft. The guide device 1 of the present invention is provided with a contact region 6 and a non-contact region 7 of the outer peripheral surface 5 of the guide roller 4 parallel to the traveling direction of the guide groove 2 on each of the opposing inner side surfaces 3 of the guide groove 2. The guide roller 4 outer peripheral surface 5 is brought into contact with the contact region 6 provided on one of the opposing inner side surfaces 3, and the non-contact region 7 provided on the other side of the inner side surface 3 is positioned so as to sandwich the guide roller 4. On the other hand, a plurality of guide rollers 4 each having a contact region 6 provided on the inner side surface 3 of the guide groove 2 and independently rotating on the common guide roller shaft 8 are provided.

Needless to say, a tough material is used for the guide groove 2 and the required thickness after processing is ensured to satisfy the mechanical strength. However, the contact region 6 provided on the inner surface of the guide groove 2 and the outer periphery of the guide roller 4 The surface 5 is processed with high accuracy to remove surface irregularities. When the guide roller shaft 8 is assembled to the inner surface 3 of the guide groove 2, the plurality of guide rollers 4 are assembled to the guide roller shaft 8 on the contact area provided on the inner surface 3 of the guide groove 2. The dimensions of each part are strictly controlled so that rolling can be performed smoothly without shaking, and pressure is appropriately applied between the guide roller 4 and the guide groove 2 as necessary.

The guide device 1 of the present invention fixes the guide roller shaft 8 to one end of a desired device or apparatus with the guide groove 2 as a fixed side, and fixes the guide roller shaft 8 to the other end of the device or apparatus using an appropriate method, or the above relationship By adopting a reverse configuration, it is possible to easily construct a guide mechanism on a device or apparatus. The guide device 1 in FIG. 1 is composed of one guide roller shaft 8 to which one guide groove 2 and two guide rollers 4 are attached. When constructing a guide mechanism on a device or apparatus, the guide device 1 shown in FIG. If necessary, a plurality of sets of guide devices 1 may be provided at opposing positions, or a plurality of guide roller shafts 8 may be combined in one guide groove 2.

FIG. 2 is a side view of the guide device 1 of the present invention shown in FIG. On the left side of the figure, there is a guide groove 2 having a substantially U-shaped cross section, and the guide groove 2 extends through the paper surface to the rear of the paper surface. A guide roller shaft 8 in which two guide rollers 4 are coaxially arranged side by side from the right side of the figure is placed so that the guide roller 4 is fitted in the guide groove 2. The two guide rollers 4 are independently rotatable on the guide roller shaft 8. Each of the guide rollers 4 has a unique contact region 6 on the opposite inner surface of the guide groove 2, and in this figure, the guide roll 4 near the tip on the guide roller shaft 8 is located in the upper side of the guide groove 2. On the side surface, the guide roll 4 far from the tip on the guide roller shaft 8 is provided as a dedicated contact area 6 on the lower inner surface of the guide groove 2. Since the outer peripheral surface 5 of the guide roller 4 is in contact with only the contact region 6 provided on the inner surface of the guide groove 2, the guide roller shaft 8 including the two guide rollers 4 which are the moving side portions of the guide device 1. When the guide roll 4 moves on the guide groove 2 from the back to the front of the paper, the guide roll 4 close to the tip on the guide roller shaft 8 rotates the front side of the guide roll 4 from the bottom to the top. The guide roll 4 far from the top end of the upper 8 rotates the front side of the guide roller 4 from top to bottom. The arrows drawn on the guide rollers 4 in the figure indicate the rotation directions of the respective guide rollers 4.

FIG. 15 is a side view illustrating the structure of the conventional guide device 9 proposed in Patent Document 1 by extracting a portion related to the guide device from FIG. 4 in the drawing of Patent Document 1, and the number in the drawing. Are the same as those used in the other figures. In the illustrated conventional guide device 9, in order to smoothly roll the guide roller 4 placed in the guide groove 2, the side opposite to the guide roller contact point of the guide groove 2 (the top of the guide roller 4 in the figure). A gap 10 having an appropriate distance that can avoid contact between the inner surface 3 of the guide groove 2 and the guide roller 4 is required. Without this gap 10, the guide roller 4 rubs against both side surfaces in the guide groove 2, thereby impairing the accuracy and stability of the guide device within a short period of time. Further, even if the gap 10 between the inner surface of the guide groove 2 and the guide roller 4 is an appropriate distance, the accuracy and stability of the guide device cannot be improved beyond a certain level due to the presence of the gap 10 itself. As described above, there is a problem that the gap 10 between the inner surface 3 of the guide groove 2 and the guide roller 4 becomes a main source of noise and vibration.

Returning to FIG. 2 again, the guide device 1 of the present invention will be described. In the guide device 1 of the present invention, the inner surface 3 of the guide groove 2 spaced 180 degrees from the contact point on the contact region 6 of each guide roller 4 is also provided. Since the non-contact area 7 of the guide roller 4 is provided, a gap 10 exists between the guide roller 4 and the inner surface 3 of the guide groove 2 as in the conventional guide device. However, in the guide device 1 of the present invention, the contact areas 6 of at least two guide rollers 4 juxtaposed on one guide roller shaft 8 are alternately arranged on the inner surface 3 of the guide groove 2. The structure has substantially no gap 10 between the guide roller 4 and the inner surface 3 of the guide groove 2. In addition, since the outer peripheral surface 5 of each guide roller 4 does not contact any part other than the contact region 6 of the inner surface 3 of the guide groove 2, the guide roller 4 rubs against the two inner surfaces 3 in the guide groove 2 at the same time. In addition, it is freed from the problem of impairing the accuracy and stability of the guide device. Also, the accuracy and stability of the guide device cannot be improved beyond a certain level due to the presence of the gap 10 itself, and the gap 10 between the inner surface 3 of the guide groove 2 and the guide roller 4 is the main cause of noise and vibration. The problem of becoming a source has also been solved.

FIG. 3 is a perspective view showing the guide device 1 of the present invention at a point where the guide groove 2 changes from the horizontal direction to the vertical direction. The guide device 1 of the present invention fixes the guide roller shaft 8 to one end of a desired device or apparatus with the guide groove 2 as a fixed side, and fixes the guide roller shaft 8 to the other end of the device or apparatus using an appropriate method, or the above relationship By using the reverse configuration, it is possible to easily construct a guide mechanism on a device or apparatus. However, when the guide groove 2 is mixed with straight lines and curves, or the direction in which the guide groove 2 is attached is other than horizontal. Even if it is, there is no problem.

Therefore, the guide roller shaft 8 can slide in a direction parallel to the guide groove 2, but does not shake in the vertical direction perpendicular to the contact region 6 of the guide groove 2.

Next, when the guide roller shaft 8 in FIG. 3 moves and reaches the point of the curved portion of the guide groove 2, it is applied to the guide roller 4 far from the tip on the guide roller shaft 8 placed in the guide groove 2. Although the load due to gravity is reduced, the outer peripheral surface of the guide roller 4 is still in contact with the contact area 6 outside the inner surface 3 of the guide groove 2, and the guide roller 4 near the tip on the guide roller shaft 8 is also the outer periphery of the guide roller 4. Since the surface is in contact with the contact region 6 on the upper side of the inner surface 3 of the guide groove 2, the guide roller shaft 8 can slide in the direction parallel to the guide groove 2 even at this point. 2 in the direction perpendicular to the contact area 6.

Further, when the guide roller shaft 8 in FIG. 3 moves upward to reach a point where the guide groove 2 is vertical, the guide roller 4 far from the tip on the guide roller shaft 8 placed in the guide groove 2 is moved. The guide device 1 according to the present invention that the guide roller 4 does not have a substantial gap between the inner surface 3 of the guide groove 2 although it is not pressed against the contact area 6 outside the inner surface 3 of the guide groove 2 due to the applied gravity. Is still in contact with the contact region 6 outside the inner surface 3 of the guide groove 2, and the guide roller 4 near the tip on the guide roller shaft 8 has an outer peripheral surface of the guide roller 4 on the inner surface of the guide groove 2. 3, the guide roller shaft 8 can be slid in the direction parallel to the guide groove 2 at this point, but is perpendicular to the contact area 6 of the guide groove 2. Not upset.

In the guide device 1 of the present invention, the guide roller 4 is always in contact with the contact region 6 of the guide groove 2 even when the guide groove 2 is curvedly formed or provided in the vertical direction. It was possible to provide a highly accurate guide device that can smoothly guide curved portions including various curvatures and that can suppress vibrations associated with traveling. In the guide device 1 of the present invention, since the guide groove 2 has a simple structure, it is easy to install the guide groove 2 having a long path, and the outer peripheral surface of the guide roller shaft 8 contacts the inner surface 3 of the guide groove 2. Since a plurality of guide rollers 4 that contact only the region 6 are provided, it is possible to provide a guide device that can take a large moving distance and moving speed.

FIG. 4 is an enlarged view of a part of FIG. 3, and is a perspective view showing the guide device 1 of the present invention. In the figure, a flange-type mounting portion 11 is provided in the guide groove 2 having a substantially U-shaped cross section for convenience in fixing to a device or apparatus, and the guide groove 2 having a substantially U-shape is provided. Of the two upper and lower side surfaces facing each other, the inner side surface 3 positioned above the two inner side surfaces 3 facing each other in the guide groove 2 is made smaller than the dimension of the side surface positioned below the side surface positioned below. A non-contact area having a shape invisible to the eye is formed on the top.

FIG. 5 is a side view of the guide device 1 according to the second aspect of the present invention as viewed from the cross-sectional side of the guide groove 2. On the left side of the figure, there is a guide groove 2 having a substantially U-shaped cross section, and the guide groove 2 extends through the paper surface to the rear of the paper surface. A guide roller shaft 8 in which two guide rollers 4 are coaxially arranged side by side from the right side of the figure is placed so that the guide roller 4 is fitted in the guide groove 2. As described above, the two guide rollers 4 are independently rotatable on the guide roller shaft 8, and each of the two guide rollers 4 has a unique outer periphery on the opposing inner surface of the guide groove 2. In this figure, the guide roll 4 close to the tip on the guide roller shaft 8 is on the upper inner surface of the guide groove 2 and the guide roll 4 far from the tip on the guide roller shaft 8 is shown in FIG. A dedicated contact area 6 is provided on the lower inner surface of the guide groove 2.

In the figure, the outer peripheral surface 5 of the guide roller 4 is inclined with respect to the guide roller shaft 8, and the contact region 6 provided on the inner surface 3 facing the guide groove 2 corresponds to the inclination of the outer peripheral surface 5 of the guide roller 4. The surface is 12. The inclined shape of the outer peripheral surface 5 of the guide roller 4 may be composed of various curved surfaces such as a simple inclined surface or a bowl shape in addition to the concave shape as shown in the figure, and the shape of the contact surface 12 is also different. It corresponds to the shape of. In the illustrated guide device 1 of the present invention, since the guide roller 4 located far from the tip on the guide roller shaft 8 can bear the thrust load of the guide roller shaft 8, the guide accuracy in the direction orthogonal to the direction of the slide motion. It became possible to improve the stability.

FIGS. 6 and 7 are cross-sectional views of the guide device 1 according to the third aspect of the present invention, as viewed from the transverse cross-section side of the guide groove 2 by cutting the guide device 1 on the guide roller shaft 8 core. The guide device 1 of the present invention shown in FIG. 1 is one in which elasticity is applied to at least one guide roller 4 among a plurality of guide rollers 4 that fit in the guide groove 2 and roll on the contact region 6. As a method of giving elasticity to the guide roller 4, as shown in FIG. 6, the guide roller 4 is made of an elastic material up to the outer peripheral surface 5, or the rim portion of the guide roller 4 is overlapped as shown in FIG. As a layer, there are a method of using a hard material for the surface layer and an elastic material for the deep layer portion, a method of adding elasticity to the shape of the guide roller 4 itself, and the like. Since the guide roller 4 is deformed in the guide groove 2 by imparting elasticity, it is important to mold the diameter of the guide roller 4 and the gap with the non-contact surface in anticipation of the deformation amount. In the above-described guide device 1 of the present invention, the frictional force and the shock absorbing force when the contact region 6 of the guide groove 2 and the guide roller 4 come into contact with each other can be increased, so that the stability when the guide device is mounted in the vertical direction is increased. As a result, the guide device can greatly reduce noise and vibration that tend to occur during a slide motion.

FIG. 8 is a cross-sectional view of the guide device 1 of the present invention described in claim 4 as viewed from the side of the cross section of the guide groove 2 by cutting the guide roller shaft 8 on the core. On the left side of the figure, there is a guide groove 2 having a substantially U-shaped cross section, and the guide groove 2 extends through the paper surface to the rear of the paper surface. In the figure, a conductive contact band 13 is provided along the guide groove 2 on the inner surface 3 of the guide groove 2, and a plurality of guide rollers 4 are arranged on the guide roller shaft 8 in parallel with the conductive contact band 13. The guide device is provided with a substantially disk-shaped contact 14 that can transmit and receive power and signals. In the drawing, one set of conductive contact band and contact is provided, but if necessary, a plurality of sets of conductive contact band and contact are provided, or the conductive contact band 13 provided on the inner surface 3 of the guide groove 2 is the edge of the guide groove 2. It may be provided in the part. Further, in the illustrated guide device 1 of the present invention, the guide roller shaft 8 is hollow, and a lead wire connected from the contactor 14 is insulated and penetrated through the space in the center so that power and electrical signals can be exchanged.

In the guide device 1, the contact 14 paired with the conductive contact band 13 is provided on the guide roller shaft 8 in parallel with the plurality of guide rollers 4. It is possible to always keep the transmission paths of the same. When trying to obtain an accurate motion trajectory with a guide device, it is often necessary to transmit power and signals, so it is required to match the motion trajectory with the power and signal transmission trajectories. However, conventionally, the guide device and the power / signal transmission device are used separately, and it is difficult to perfectly match the movement trajectory of the guide device with the motion trajectory of the power / signal transmission device. In some cases, it was necessary to add a mechanism to resolve the contradiction between the movement trajectories. In the guide device 1 of the present invention, the motion trajectory of the guide device and the motion trajectory of the power / signal transmission device can be completely matched, so that the motion trajectory of the guide device and the motion trajectory of the power / signal transmission device are inconsistent. A mechanism or device such as a cord reel device or a pantograph that absorbs the light becomes unnecessary, and the device and device can be reduced in size and cost can be reduced.

  FIG. 9 shows the guide device 1 of the present invention in which the outer peripheral surface 5 of the guide roller 4 is contact-rolled on the contact region 6 provided on the opposing inner surface 3 of the guide groove 2 having a substantially U-shaped cross section. It is the perspective view which showed the outline. In the figure, a rack gear 15 is further provided along the guide groove 2, and a pinion gear 16 that is paired with the rack gear 15 is provided on the guide roller shaft 8. In the illustrated guide device 1, the rack gear 15 is provided on the inner surface 3 of the guide groove 2, but the rack gear 15 may be provided at an edge portion of the guide groove 2. In this case, the pinion gear 16 fitted to the rack gear 15 is arranged near the root of the guide roller shaft 8. In the same figure, a combination of a rack gear 15 and a pinion gear 16 is depicted as a power transmission mechanism, but this is provided with a chain extending on the inner surface 3 of the guide groove 2, while the chain wheel is replaced with the pinion gear 16. It may be a guide device.

  FIG. 10 is a side view of the guide device 1 according to the present invention as viewed from the lateral cross-section side of the guide groove 2. In the figure, along a guide groove 2 shown as a cut surface, a power transmission line 17 also shown as a cut surface is provided, and a power transmission point 18 is provided on the guide roller shaft 8. In the illustrated guide device 1, the power transmission line 17 is provided on the inner surface 3 of the guide groove 2, but the power transmission line 17 is provided on the outside of the side wall of the guide groove 2, while the power transmission point is coupled to the power transmission line 17. 18 may be disposed near the tip of the guide roller shaft 8 extended by opening the side wall of the guide groove 2. In the same figure, a power transmission mechanism in which a rope is connected to a power transmission point is depicted, but there is no problem even if this is replaced with a power transmission mechanism in which a chain or a transmission belt is connected to the power transmission point. When the guide groove 2 has a curved portion, it is necessary to make the power transmission point 18 rotatable by making the guide roller shaft 8 rotatable.

  In the guide device 1 of FIG. 10, the power for the sliding motion can be transmitted to the guide roller shaft 8 provided with the power transmission point 18 by running the power transmission line 17 provided along the guide groove 2. By providing the guide groove in the vertical direction, it is possible to supply power for sliding in addition to the original function as a guide device even in a guide device that requires a long slide movement such as an elevator device. is there. Moreover, an elevator apparatus that can move in directions other than the vertical direction can be realized by providing a curved portion in the middle of the route and setting the guide groove in a horizontal direction or an oblique direction. In this case, by providing a plurality of sets of power transmission points 18 and power transmission lines 17 on the guide roller shaft 8, it is possible to drastically improve operational safety.

  Generally, when it is desired to obtain a highly accurate slide motion locus using a guide device, it is often necessary to transmit not only the slide motion but also power. In the above case, it is required to match the movement trajectory with the power transmission trajectory, which is also supplied to the market as a product. However, the above-mentioned products supplied to the market are limited to small-sized guide devices, and are dedicated to circular motion with a fixed radius and a linear guide device provided with a power transmission device in a position parallel to the guide device. Except for the guide device, it can be said that there is virtually no highly accurate guide device in which a power transmission mechanism is provided in a guide device that obtains a motion trajectory that combines linear motion and curved motion. The motion trajectory of the guide device and the motion trajectory of the electric or power transmission device can be completely matched, and the power transmission mechanism is provided in the guide device that provides a motion trajectory that combines linear motion and curved motion. We were able to provide a high guide device.
