Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traveling structure of a combination structure type in which a roller guide portion for guiding and traveling in contact with a guide roller attached to a carrier or the like is reasonably combined with a main mounting portion of a rail. For a guide rail for a car.

[0002]

2. Description of the Related Art Conventionally, in order to move equipment such as a conveyor that circulates and a carrier in a required section, most of them are used as guide means by a guide roller attached to the carrier being brought into contact with a guide rail. The method of moving it is adopted. For this reason, various measures have been taken so that the contact portion (roller guide portion) with which the roller guides the guide rail can be accurately moved smoothly.

Usually, a guide roller with a flange is guided so as to abut on a corner portion formed in a member forming the rail as a roller guide portion of the guide rail, or a guide roller is provided in a guide groove provided in the rail. It is common to guide the vehicle along the line. However, it is difficult to improve the accuracy by any of these methods. Therefore, for example, Japanese Patent Application Laid-Open No. 9-175387 and Japanese Patent Application Laid-Open No. 10-324 related to the prior application of the present inventors
By using a guide rail having a structure as disclosed in Japanese Patent Laid-Open No. 237 or Japanese Patent Laid-Open No. 11-208859, it is possible to obtain a highly accurate guiding means.

In addition, as shown in FIG. 18, for example, rectangular grooves 73 are formed along the axis on both sides of a member having a required cross-sectional shape as a main body 71 of the guide rail 70, and the grooves 73 on both sides are formed. The round bar 74 is fitted to the main body 71, and the portions of the round bar 74 are press-fitted from both sides of the groove 73 so as not to come off.
It is proposed that the exposed portion of the roller is used as the guide portion 72 of the roller.

[0005]

However, the above-mentioned JP-A-9-175387 and JP-A-10-32423.
In the guide rails proposed by Japanese Laid-Open Patent Publication No. 7-200859 or Japanese Laid-Open Patent Publication No. 11-208859, as shown in FIG. 17, all are portions that support the guide portion 62 of the roller as the main body of the guide rail 60. Since the structure is formed so as to integrally project laterally from 61 (support base), it is inevitable that the main body 61 (support base) must be manufactured together with the portion, which inevitably increases the manufacturing cost. Further, there is a problem in that it takes more work to construct a running path having a curved portion and a height difference in the manufacturing thereof, and the degree of freedom cannot be obtained even if a highly accurate one is obtained.

Further, the guide rail 70 of the type shown in FIG. 18 is apparently rational and effective, but when a long guide rail is produced, its roller Since the round bar 74 portion which becomes the guide portion 72 has to be fixed by press fitting into the groove portion 73 provided on the side portion of the rail main body 71, not only the manufacturing cost increases, but also a jig is required to improve the dimensional accuracy, and It only stays straight. Therefore, there is a problem that it is practically impossible to construct a curved portion or the like.
In addition, unless the round bar member is held in the groove of the support base by sufficient press fitting, there is a problem that the round bar member 74 floats out of the groove portion 73 during use. In particular, in a place where the temperature difference is large, when the support base and the round bar material have different linear expansion coefficients, the deviation in the fixed portion becomes more remarkable.

Further, since the guide rails in a conventional conveyor such as a conveyor line are mainly composed of a combination of rough shaped steels, they are unsuitable for highly accurate transportation. Therefore, under the present circumstances, the guide rails, which are the transfer paths that form the highly accurate transfer line, are mainly flat and are limited to the range where the straight line portion is formed.

The present invention has been made in order to solve the above-mentioned problems, and has a simple structure and high accuracy, and a running path not only in a straight line portion but also in a curved portion or a three-dimensional portion. It is an object of the present invention to provide a traveling guide rail that can be configured.

[0009]

In order to achieve the above object, the traveling guide rail according to the first aspect of the invention is a guide rail having roller guide portions on both sides with a required width, and the roller guide is provided. The guide member that forms the main body of the portion and a support member that sandwiches a part of the guide member so as to be exposed to the outside and that is fixedly arranged on both sides in the width direction in a non-releasable manner, and the exposed surface of the guide member And a side surface portion of the support member to form a roller guide portion.

In the present invention, as the guide rail for traveling, the support member is divided into, for example, a required length divided into upper and lower parts,
On both sides in the width direction, concave grooves capable of receiving the outer shape of the guide member are formed symmetrically, and the pair of upper and lower support members receive the guide members in the concave groove portions on both sides and clamp the support members. By fastening and fixing with a tool, the guide member is integrally formed along both sides of the support member. As for mounting on a machine base or the like when it is used as a guide rail, the supporting member can be processed to be arbitrarily mounted. The guide member is formed so as to be held in the recessed groove portion formed in the support member, so that the guide member does not disengage even if it receives an external force during use, and the guide member is integrated with the guide member. By forming a roller guide portion with the side surface of the support member adjacent to the portion, a guide roller such as a carrier can be accurately guided.

According to the present invention, if a guide member having a high processing precision is used and a surface treatment is performed to increase the mechanical strength, a combination of the two makes it possible to obtain a high level which has never been possible before. The effect is that a quality guide rail can be obtained. Moreover, since the guide member, which is the main part of the guide rail, is sandwiched by the support members to form the roller guide portion, not only steel material but also non-metal material can be selected and used as the guide member. Regarding the cross-sectional shape of the guide member, there is an advantage that a member having a shape suitable for the application can be adopted, and the structure can be simplified to provide a guide rail having an arbitrary cross section.

A second aspect of the present invention is a guide rail having a roller guide portion on one side of a support portion having a required width, the guide member forming the main body of the roller guide portion, and a part of the guide member exposed to the outside. And a support member that is sandwiched from above and below and fixed irremovably on one side in the width direction, and a roller guide surface is formed by the exposed surface of the guide member and the side surface portion of the support member. To do.

According to the present invention, by arranging the roller guide portions symmetrically and arranging the two guide rails in parallel with each other at a required interval, the roller guide portions are widened in the width direction. Can guide you through your career.
Therefore, it is possible to rationally form a so-called wide traveling path by using a narrow supporting member.

In the first invention or the second invention, the support member sandwiching the guide member and constituting the roller guide portion on the side surface is composed of at least two pieces and integrally formed by a fastener at a predetermined interval in the axial direction. It is preferable that the structure is fixed by clamping (third invention). Also, the guide member,
It is preferable that at least 1/2 or more of the cross section is sandwiched by the concave groove portions provided in the support member (fourth invention). With this configuration, the guide member can be integrated by being held by the supporting member in the concave groove portion formed on the side thereof, and the side surface portion of the supporting member and the exposed portion of the guide member rationally configure the roller guide portion. There is an advantage that the guide member can be manufactured and provided with high precision by a simple structure, which is stably maintained without coming off during use.

The guide member is formed of a material having a circular cross section, and a holding groove of a supporting member for holding the guide member is formed with a concave groove portion having a concave curved surface, and the guide member is fitted into the concave groove portion. It is preferable that the support member is clamped and fixed by a fastener (fifth invention). This has the advantage that, for example, a polished high-precision round bar can be easily incorporated as the guide member that constitutes the main body of the roller guide portion, and the precision of the guide rail can be easily increased. .

Further, the guide member is formed of a material having a rectangular cross section, and a holding groove of a supporting member for holding the guide member is formed with a concave groove portion into which the guide member is fitted, and the concave groove portion is formed with the concave groove portion. It is preferable that the guide member is fitted and the support member is clamped and fixed by a fastener (sixth invention). In this case, the roller guide portion serving as the guide rail having the prismatic ridge portion has an advantage that it can be easily obtained with improved accuracy.

The support member for sandwiching the guide member may be a plate member having a required width formed in such a manner that a groove portion for sandwiching the guide member is formed on at least one of the plate members in the width direction. It is preferable that the guide rail is configured in this manner (seventh invention). With such a configuration, there is an advantage that the weight of the guide rail can be reduced.

In the first invention, the third invention to the seventh invention, the supporting members for sandwiching the guide member and forming the roller guide portions on both sides are arranged intermittently at a required interval. It is possible (eighth invention). By doing so, it is possible to reduce the number of guide rail constituent members, reduce the weight, and reduce the cost. Further, there is an advantage that it becomes possible to facilitate workability when forming the curved portion of the guide rail.

Further, when the guide member is clamped, the supporting member is constructed so as to also serve as a joint of the guide rail by shifting and fastening the longitudinal end portion of the supporting member at the connecting portion of the guide member. Is preferred (ninth invention). By doing so, there is an advantage that the connection of the guide member can be ensured and the long guide rail can be connected without the need for a separate metal fitting.

As for the supporting piece 2c of such a plate material, a long one can be accurately manufactured by, for example, a forming process, so that the cost can be reduced. Of course, it can also be manufactured by pressing.

FIG. 9 shows a partial vertical sectional view of the guide rail of the third embodiment and the carrier supported and guided by the guide rail. Since this embodiment is basically the same as the above-described embodiment, the same parts as those described above are denoted by the same reference numerals except for different parts, and detailed description thereof is omitted.

Guide rail 1B of the third embodiment
Indicates that the support member 2B has a square cross section (substantially a rectangular cross section).
Lower support part piece 2e of the upper part and upper support part piece 2 formed of a plate material
The guide members 4 and 4 having a circular cross section are sandwiched between the concave groove portions 3 and 3 formed at both ends in the width direction by c and are integrally formed by the hollow rivet 7. Even with such a configuration, similarly to the above-described one, the roller guide portions 5 can be formed on both sides, and the guide rollers 31 can be guided by the roller guide portions 5 to move the carrier 30. In addition, the upper support piece 2c may be formed with the reinforcing rib protrusion 2c ″ straddling a part of the portion forming the concave groove portion 3 and the intermediate flat portion, if necessary.

Further, FIG. 10 shows a plan view of another embodiment. Guide rail 1 according to the fourth embodiment
C is a modified form in which the one shown in the third embodiment is also applied to the curved portion D. Therefore, the same or similar parts as those in the above-described embodiment are designated by the same reference numerals as those in the above-mentioned embodiment and the description thereof is omitted (the same applies hereinafter).

In the guide rail 1C of this embodiment, the upper support portion piece 20c on the upper side has a short length dimension formed by bending a plate material into the above-mentioned cross-sectional shape, and a mounting hole is provided at the center thereof. The guide members 4 and 4 having the required dimensions are formed on the long lower support piece 20e, which is formed continuously and has an arcuate groove at both ends in the width direction with a rectangular cross section having the required dimensions. (Not shown), and the upper support piece 20e is fastened with bolts 9 at predetermined intervals to be integrally formed.

In the curved portion D of such a guide rail 1C, concave groove portions 3 ', 3 "are formed in concentric circles with a required radius on both sides in the width direction of the lower support portion piece 20f, and the upper support portion is formed. For example, as shown in FIG. 10, the piece 20e ′ is a dovetail shape in a plan view in which the outside of the curve is wide and the inside is narrow, and the piece 20e ′ is formed to have an arcuate groove having a required radius both inside and outside. By using intermittently like the linear guide rail portion E, the guide members 4 ', 4 "that are bent in an arc shape along the concave groove portion formed in the lower support piece 20f are used. In the above-mentioned manner, it is sandwiched and integrally fixed to form. At this time, both ends e, e of the bending guide members 4 ', 4 "are formed into a straight line having a required length, and are formed in a U shape so that the curved portion D is formed into an accurate arc. Further, if the ends of the both ends are abutted against the linear guide members 4 and 4 and sandwiched between the upper support pieces 20c, a reliable connection can be made without difficulty.

In this embodiment, the upper support piece 20c,
20e 'is downsized and the guide member 4 (4',
4 ″) can be integrated without being sandwiched, so that the cost can be reduced. In some cases, the lower support piece 20e can be fragmentary like the upper support piece 20c. .

A guide rail 1A formed by a combination of a support member 2A and a guide member 4 which are formed by bending the above-mentioned plate material is obtained by changing the shape of the support base 15 thereof, as shown in FIG. In addition, the traveling base can be formed by mounting the support base 15 on the support body 8 with the fastening member 16 provided with a female screw fitted to a part of the die member made of aluminum interposed therebetween. Further, FIG. 12 shows an example in which the guide rail 1A is attached to a support stand 17 having an inclined support surface, and when formed in this manner, a three-dimensional traveling such as an inclined traveling path other than a plane is formed. It can be used by forming a channel.

Furthermore, as the guide member 4,
Although the guide rails having a circular cross section are described in the above embodiment, in addition to this, FIG.
As illustrated by (d), the guide member 4A having a hexagonal cross section or the guide member 4B having a quadrangular cross section can also be used. In the case of using the guide members 4A and 4B having a rectangular cross section, A guide member 4 to be sandwiched in a recessed groove portion (collectively referred to as recessed groove portion 3C) provided on the side of the support member (collectively referred to as support member 2C).
It is shaped so as to hold at least half of the cross section of A (4B). In this case, the guide member 4A (4B) sandwiched between the upper and lower support part pieces is partly exposed to the outside and held by the recessed groove part 3C on the support member 2C side, and is stably held without disengagement. . Therefore, the support member 2C and the guide member 4A (4B) can be integrated into a simple and effective guide rail 1A ', 1A ", 1'or 1B'.

Next, as shown in FIG. 14, a guide member 4 is sandwiched and incorporated only on one side surface side in the width direction of a support member 200 composed of upper and lower support portion pieces 201 and 202. In other words, a roller is provided only on one side. It is a guide rail 10 including a guide portion 5.

The guide rail 10 of this embodiment is a modification of the above-mentioned guide rail 1 and has the same basic structure as that of the above-mentioned guide rail 1. A concave groove portion 3 similar to the one described above is provided on one side of the guide member 4, and the guide member 4 is held and sandwiched in the concave groove portion 3 so as not to be detachable. The upper and lower support pieces 201 and 202 are provided with stepped fastening holes 6 at a required pitch in the longitudinal direction and are integrally fastened with a hollow stud 7, and the inside of the hollow stud 7 is used to support the support member. It is a structure that can be used by bolting to 8.

The guide rollers 31, 31 of 0 are brought into contact with the roller guide portions 5 of the guide rails 10, 10 to be guided. Thus, the guide rail 1 of the present embodiment
Since 0 has the roller guide portion 5 only on one side, there is an advantage that the distance L (interval) between the roller guide portions 5 and 5 to be arranged in parallel can be arbitrarily set. In this example, the roller guides 5 and 5 are on the inner side, but the same function can be achieved by using the roller guides 5 facing outward.

In the case of this type of guide rail 10, although not shown in the drawings, if necessary, the holding portion of the guide member 4 in the supporting member 200 (the concave groove portion may be formed on a curved surface drawn with a required radius as described above). It is also possible to form curved rails.

FIG. 15 shows a guide rail 10A in which a roller guide portion 5 is formed only on one side similarly to the guide rail 1A using the plate material of the second embodiment. Since the structure is the same as that described above, the reference numerals are given and detailed description is omitted. This type of guide rail 10
Even in A, it is used in the same manner as the guide rail 10.

FIG. 16 shows another embodiment of the guide rail having the roller guide portion 5 on one side. In this guide rail 10B, it is possible to adopt a configuration in which a mold member is used for the lower support piece 203 as the support member 210, and a plate material is bent as the upper support piece 204 to sandwich the guide member 4 therebetween. .

The guide rail 10B of such a type has an advantage that the mounting conditions can be arbitrarily set by changing the size of the lower support piece 203 and utilizing the space portion for mounting.

As the constituent member of the guide rail in the above description, a material such as a polished steel material or plastic ceramics is used as a circular or rectangular guide member forming the roller guide portion. Further, as the supporting member, a material such as a steel material, an aluminum alloy, a thermosetting resin molded product, or ceramics can be used according to the configuration.

As explained above, in the guide rail according to the present invention, an effective guide rail can be obtained with a very simple structure by skillfully combining the guide member and the support member constituting the roller guide portion. Therefore, it is possible to provide a product with reduced manufacturing cost and improved accuracy. It should be noted that the above-described embodiments describe representative ones of the present invention, and the present invention is not limited to these, and a gear (rack or the like) or other one having functionality is added to a part of the support member. Are possible, and these belong to the technical scope of the present invention.
