Description

  The present invention relates to a carrier in a conveying means configured to be able to move efficiently to suspend or support a moving object, and a joinery carrier using the carrier.

  2. Description of the Related Art Conventionally, in a suspended article conveying apparatus, such as a conveyor, which has been widely used, carriers that are arranged at a predetermined interval along a guide rail that constitutes a conveyor line are connected by a chain and are pulled and driven. A system is adopted in which an article conveyed to a hanging tool (for example, a hanger) provided on each is suspended and transferred to a required location.

  As an automatic door device provided at an entrance of a building or the like, there is known a configuration in which a hanging door is moved laterally along a guide rail mainly by a chain drive. Many proposals have already been made on the carrier used to move the door in such an automatic door device. As an example, in a guide rail having an opening formed in a downward and axial direction and having a cross-sectional bag shape, two guide rollers are arranged with the upper surfaces on both sides of the opening serving as guide portions, and these guide rollers. The carrier (runner) having a total of four sets in two sets at appropriate intervals in the front-rear direction is provided so as to be able to run, and the door is suspended by a vertical axis suspended from the center position of the carrier. One is known from US Pat. A configuration similar to that disclosed in Patent Document 1 is known from Patent Document 2, Patent Document 3, and the like. Alternatively, in addition to the four rollers as described above, Patent Document 4 or the like is provided with a side roller that can run along the opening of the guide rail while contacting the opening edge of the guide rail. Are known.

  However, in the prior art, as disclosed in Patent Documents 1 to 3, there are four carriers called runners that move along the guide rail in any one runner body. Are installed under the same conditions. Therefore, when the door is hung and moved by the runner, the four rollers are theoretically guided in contact with the guide rail, but the guide rail guide surface is practically left and right. It is hard to say that they are always at the same level, and sometimes they are in a state of undulations. As a result, since two or three rollers run substantially in contact with the guide surface of the rail, the frictional resistance between the guide surface of the rail and the peripheral surface of the roller increases, and the load shared by each roller is increased. Acts irregularly. Therefore, there is a problem that a large amount of power is required when the runner is run to open and close the door. Therefore, in spite of the fact that the runner can be moved with a little power, the actual situation is that the hanging door is opened and closed by using an excessive driving force.

  Further, as disclosed in Patent Document 4, the number of runner rollers guided and supported by the guide rail is two, and the rollers (side rollers) that are guided in contact with the edges of the slits to prevent shake are front and rear. However, there is a problem in that it is not possible to stop the deflection of the guide rail in the direction of travel. Such a system has a problem that it is unsuitable for a suspension type conveying means that travels at a high speed.

  Such a situation is the same for a carrier in a suspending type conveying apparatus (for example, a suspended conveyor) regardless of only the opening / closing operation of the door. For this reason, in a conveyor that requires a large number of carriers to be connected, a large driving force is required due to an increase in frictional resistance, resulting in a problem that mechanical efficiency is lowered during operation and energy loss is increased, resulting in an increase in operating cost. There is a point.

  The present invention has been made to solve such a problem, and the guide rollers of the carrier in the suspension type conveying means all come into contact with the guide surface of the guide rail to share the load, and the guide travel can be performed. It is an object of the present invention to provide a carrier and a joinery carrier in a transport means that can smoothly run while preventing generation of a typical load.

In order to achieve the above object, the carrier in the conveying means according to the first invention is:
In a carrier that travels while being guided by guide rails that are provided with guide portions at right and left at a required interval along the travel axis, a plurality of guide rollers that are disposed on the left and right are support shafts that are attached to the left and right individual support frames. The left and right support frames are rotatably supported at a required interval, and are pivotally supported on the coupling member at the central portion thereof by a pivot shaft that is orthogonal to the traveling axis, and are supported by the left and right support frames. Each of the guide rollers to be attached is configured to rotate in contact with all along the guide surface of the guide rail.

  In the above invention, the connecting member for connecting the left and right support frames to each other by the pivot shaft is connected to the connecting member for connecting the object to be conveyed in the vertical direction intersecting the traveling guide surface. (2nd invention).

  In the second aspect of the invention, the connecting member may be a shaft / screw connecting body in which a portion protruding from the connecting member is suitable for connecting an object to be conveyed (third aspect).

Moreover, in order to achieve the said objective, the fitting carrier which concerns on 4th invention is
In a joinery carrier that is attached to a building and that can be guided and moved by guide rails that are arranged at required intervals on the left and right along the traveling axis, a plurality of guide rollers arranged on the left and right are attached to the left and right individual support frames. The left and right support frames are pivotally supported by a pivot shaft that is orthogonal to the traveling axis at the center of the left and right support frames. Each guide roller to be attached to the support frame is configured to rotate and run in contact with all along the guide surface of the guide rail.

  In the fourth aspect of the present invention, the support frames arranged on the left and right sides are made of a metal plate having a required size with a rigid shape, and are mutually supported by a pivot shaft through a coupling member arranged between the support frames at the center. It is preferable that the guide roller be arranged on the outer side of the support frame (the fifth invention).

  In the fourth invention or the fifth invention, it is preferable that the support frame is bent at both longitudinal end portions thereof, and the both end portions of the left and right support frames are combined inward so as not to interfere (sixth invention). ).

  In the fourth to sixth aspects of the invention, the connecting member constituting a part of the carrier has a required length of a connecting member that is attached in the vertical direction intersecting the traveling guide surface of the guide rail and connected to the door. Preferably, the connecting member is attached at a position close to a pivot shaft that pivotally couples and supports both the support frames (seventh invention).

  In the first invention, the plurality of guide rollers attached to the carrier are allowed to run while being in contact with the guide portions of the guide rails individually on the left and right sides, and the left and right frames to which the guide rollers are attached are arranged in the center portion. Since the guide member is pivotally supported by a pivot shaft so that it can be swung up and down, all guide rollers are always moved along the guide part of the rail when traveling even if the left and right guide surfaces of the guide rail are not equal. Will run in contact. Therefore, since each guide roller shares the load and travels, it is possible to prevent the generation of an irregular load and to smoothly travel. Therefore, the frictional resistance at the time of running can be reduced and the power required for driving can be remarkably reduced.

  According to the second aspect of the invention, the connecting member that connects the left and right support frames by the pivot shaft is arranged with the connecting member that connects the transported object in a direction intersecting the travel guide surface. The object to be conveyed can be supported by being hung or lifted without hindering traveling, and the load acting through the connecting member always acts on the center of the carrier. Overall, in other words, it is possible to travel by being shared by each guide roller, and it is possible to travel in a well-balanced state. In addition, there is no problem when moving on a curve or the like.

  According to the third aspect of the present invention, the connecting member protruding from the coupling member located at the center of the carrier is a shaft body or a screw coupling body (for example, a screw shaft), so that it is easy to attach the transport unit coupled thereto. can do.

  According to the fourth aspect of the invention, by using this carrier as a runner for hanging and opening a joinery, for example, a door, a plurality of guides arranged on the left and right as in the case of the first and second aspects of the invention. Since all the rollers are in contact with the guide surface of the guide rail, all the rollers can share the load and run smoothly, so the doors can be opened and closed by moving with little power. be able to. Of course, there is an effect that it can be operated with light power as a support carrier for suspending joinery other than the door.

  According to the fifth aspect of the present invention, the support frame made of a metal plate and having a rigid shape is connected to each other by the pivot shaft with the coupling member interposed at the center, and both the support frames are pivot shafts. Since each of the guide rollers is supported by being pivoted on the basis of the body, the guide rollers attached to the support frames can be moved while being freely displaced from side to side according to the state of the guide surface of the guide rail. Thus, the load is shared and the vehicle can smoothly run.

  According to the sixth aspect of the present invention, the metal support frame is configured by combining the ones that are bent at both longitudinal end portions, thereby increasing the rigidity without expanding in the width direction and increasing the rigidity. It can be stored inside a guide rail that guides and supports a door or the like, and can be used as a carrier (runner) of a fitting.

  Further, according to the seventh aspect, the connecting member provided in the vertical direction from the connecting member disposed in the central portion constituting the carrier is a position where the left and right support frames provided with the rollers are pivotally attached to the connecting member. By being provided in the vicinity, it is possible to run while sharing the load with respect to each of the guide rollers without greatly deviating, so that a smooth operation can be performed. And there exists an advantage that it can be made to respond | correspond to driving | running | working other than a straight line by supporting a fitting, such as a door, with respect to a carrier.

  Next, specific embodiments of the carrier in the conveying means of the present invention will be described with reference to the drawings.

  FIG. 1 is a front view showing an embodiment of the conveying means according to the present invention. 2 is a view taken along the line AA in FIG. 1, FIG. 3 is a front view (a) and a plan view (b) showing a single carrier, and FIG. 4 is an enlarged view taken along the line BB in FIG. The CC cross-sectional enlarged view (b) in sectional drawing (a) and FIG.3 (b) is each shown.

  In the conveying means 1 in this embodiment, a suspension support shaft body is suspended from a carrier 10 that can run along a guide rail 2 supported by a support bracket (not shown) in the structure, and the suspension member attachment shaft body 17. The conveyed product is suspended and conveyed directly or via the suspension member 3. Note that the suspension member 3 is a support housing having a required length, and a suspension tool (not shown) is separately attached to the suspension member 3 so that an object to be conveyed is conveyed by the suspension tool. However, this shape is not particular.

  As shown in FIGS. 3 and 4, the carrier 10 includes a pair of left and right support frames 11 and 11 ′ provided with travel rollers 13 arranged at the front and rear at a required interval, and the support frames 11 and 11. It is composed of a connecting member 15 that is disposed between and supports the two support frames at the intermediate portion.

  The support frame 11 (both of which have the same shape, one of which will be described) is formed in a shape that possesses rigidity by bending a metal plate of a required dimension toward the inside during assembly at both ends in the longitudinal direction. The rollers 13 and 13 are rotatably mounted on a support shaft 12 that protrudes outward in the front-rear direction at a predetermined interval and has a tip portion fixed thereto. The support shaft 12 of the roller 13 is fastened and fixed to the inner surface side of the support frame 11 with a nut 12c with the tip portion thereof as a screw shaft 12a. The roller 13 incorporates a ball bearing 13a so that the peripheral surface of the base end portion 12b of the support shaft 12 serves as a rolling surface of the bearing (but is not limited to this). The support frame 11 having such a structure is disposed at a required interval in the traveling direction in the running direction with the attached roller 13 facing outward, and is pivotally attached to the coupling member 15 by the pivot shaft 14 at the center.

  The coupling member 15 is configured such that the support frames 11 and 11 'are arranged on both side surfaces and can be integrally coupled to the pivot shaft 14 through a shaft hole 15a penetrating the three at the center portion. A hanging shaft hole 15b penetrating in the vertical direction is provided at a position before or after the pivot shaft hole 15a. A suspension member mounting shaft body 17 is fixed to the suspension shaft hole 15b by inserting the upper half portion 17b so that the lower half portion is a screw shaft 17a and hangs downward from the coupling member 15. Yes.

  On the other hand, the guide rail 2 has a pair of rail members 2a, 2a formed in a groove shape facing each other at a required interval with the groove side facing inward, and the support members 4 are respectively supported by the support members 4 on the upper surface portions of both rail members 2a. (Not shown) and installed. The inner lower surfaces of the rail members 2a and 2a are guide surfaces 2b.

  The carrier 10 formed in this way is formed on a guide rail 2 having guide surfaces 2b on the left and right in the traveling direction at a predetermined interval as a traveling path, and on the guide surfaces 2b and 2b on both sides of the support frames 11 and 11 '. The two rollers 13 are allowed to run in a state where all the rollers 13 are in contact with each other, and a suspended member is attached to a suspended member mounting shaft body 17 that hangs down from the coupling member 15 so that an object to be conveyed can be suspended and conveyed. It is made like.

  For example, as shown in FIG. 1, the carrier 10 has two carriers 10, 10 as a suspension member 3 on a suspension member mounting shaft body 17 suspended from each coupling member 15. It is also possible to suspend and transport the object to be transported by mounting and this connecting rod (suspending member 3). When such a method is employed, an article having a large size can be handled. In this embodiment, the connecting member 5 is attached to the upper surface of the hanging member 3 as a connecting structure between the hanging member 3 and the hanging member attachment shaft body 17, and the inside of the attaching member 5 is rotated from the outside. A nut 6 to which a force can be applied is disposed, and the nut 6 and a screw shaft 17a of the suspension member mounting shaft body 17 are screwed together so that the vertical position can be adjusted.

  As a means for driving the carrier 10, although not shown, a connecting shaft that protrudes from the upper surface of the coupling member 15 is provided, and a power transmission roller is attached to the upper end of the connecting shaft so as to be placed at an appropriate position on the upper side of the traveling path. The carrier is driven to travel by sequentially moving the power transmission roller by the rotating screw by the arranged screw driver. Alternatively, the connecting chain or rod to be pulled while being connected to the lower part of the coupling member is pulled and driven by a prime mover. In addition, what is shown by FIG. 1 is what was moved manually.

  In this way, when the carrier 10 is driven and travels on the guide rail 2, the pair of support frames 11, 11 ′ disposed on the left and right sides of the pair of support frames 11, 11 ′ are pivotally supported by the coupling member 15 at the center thereof. The front and rear rollers 13 and 13 attached to each of the support frames 11 and 11 ′ are swingably supported without being restricted, and are individually abutted against the guide surface 2 b of the guide rail 2. To do. Accordingly, each roller 13 travels while sharing a load acting on each of the rollers 13 along the guide surface 2b, and even if the guide surface 2b is slightly displaced up and down, an uneven load does not act on the roller 13. As a result, the rail guide surface 2b rolls with a substantially uniform frictional force and can travel lightly.

  According to such a transport device in which a large number of carriers 10 are arranged, each carrier 10 can travel lightly, and therefore, in the transport line connecting them, the actual driving force is reduced, and not only the straight portion but also the curve is curved. Even in the portion to be drawn, it can be made to travel without difficulty, and a highly economical conveying device can be realized. Further, the carrier can be used not only for suspended conveyance but also for conveyance for supporting upward along the guide rail for the same purpose.

  Next, FIG. 5 shows an overall perspective view of the door which shows a perspective view of the main part of the joinery carrier according to the present invention. FIG. 6 is a perspective view showing the appearance of the mounting portion of the carrier and the door, and FIG. 7 is a longitudinal sectional view of one embodiment showing the connecting portion between the carrier and the door.

  A plurality of (substantially two) joinery carriers 20 of this embodiment are incorporated into guide rails 30 that are horizontally attached by fixtures at a plurality of locations on an upper entrance ridge (not shown) of a building, and a door is hung on them. A door is suspended via a lower shaft body 26 and is arranged to be freely opened and closed. Such a joinery carrier 20 is useful when used for an automatic door that is manually opened and closed or opened and closed by a driving device (not shown).

  The joinery carrier 20 (hereinafter simply referred to as the carrier 20) will be described in more detail. As in the above-described embodiment, the carrier 20 has support frames 21 and 21 ′ formed by bending a metal plate of a required dimension in a U-shape at both ends in the longitudinal direction, and the folded portion is inward. In this way, the coupling member 25 is interposed between the support frames 21 and 21 ′, and the coupling member 25 is pivotally supported by the pivot shaft 24 at the center in the longitudinal direction of the support frames 21 and 21 ′. 4 and a total of four rollers 23 are disposed on the support shaft 22 that protrudes outward at a predetermined interval at the front and rear positions of the pivot shaft 24, two on each of the left and right. It is.

  As described above, the coupling member 25 is sandwiched between the support frames 21 and 21 ′ as described above, and is connected to each other by the pivot shaft 24 at the center thereof, and faces downward to either the front or rear of the pivot shaft 24. A mounting hole 25a penetrating the shaft is provided so as to be orthogonal to the traveling axis, and a door suspension shaft body 26 is fixed to the mounting hole 25a.

  The door suspension shaft body 26 is inserted into a suspension mounting bracket 27 embedded in the upper corner of the door, and is suspended by a suspension position adjusting means 28 provided on the suspension mounting bracket 27. The adjustable connected.

  The door hanging mounting bracket 27 includes a box-shaped frame 28a formed by a combination of a metal plate embedded in an upper corner of the door and a connecting member, and a mounting member 28b fitted and fixed therein. The suspension position adjusting means 29 is composed of a set of adjusting gears incorporated in a lateral slit portion 28c formed inside the mounting member 28b.

  The hanging position adjusting means 29 is provided with a pair of adjusting gears 29a and 29b in the front-rear direction (longitudinal direction relative to the thickness of the door) of the hanging mounting bracket 27 inside the slit of the mounting member 28b. In addition, a screw hole is formed in the shaft center of the gear 29a located on the inner side (back side), and a screw portion of the door suspension shaft body 26 hanging from the carrier 20 is inserted into the screw hole of the gear 29a. They are connected by screwing. The gear 29b located outside is supported by the shaft 29c and meshed with the gear 29a connected to the door suspension shaft body 26, and a part of the outer periphery thereof is eroded from the slit 28c of the mounting member 28b. The structure is such that it can be rotated by operating the outer periphery of the gear 29b with a finger from an opening 28d (normally the cover 28f is attached) provided in the frame 28a. The rotation of the gear 29b By rotating the other gear 29a engaged with the screw hole, the height position of the door suspension shaft body 26 screwed into the screw hole, in other words, the door suspension position can be adjusted.

  The guide rail 30 that supports and guides the joinery carrier 20 is formed with a moving space 33 having a width in which a door hanging shaft 26 hanging from the carrier 20 moves in the center in the width direction intersecting the guide direction. The guide surfaces 32 are provided on both sides of the moving space 33. Specifically, so-called groove-shaped members 31, 31 that are bent in a U-shape are arranged to face each other at a required interval, and the upward surface inside thereof is used as a guide surface 32, with a slight depression. It has a cross-sectional shape.

  The guide rail 30 thus configured is mounted on the upper opening (entrance / exit) of the building with the mounting seat at the moving space 33 on the lower side, and the carrier 20 is incorporated inside the guide rail 30. The door 35 is suspended from the door suspension shaft body 26 suspended from the coupling member 25 via the mounting bracket 27 and used.

  As described above, the carrier 20 is provided with the coupling member 25 that suspends the door 35 at the center, and both support frames 21 and 21 ′ having the rollers 23 arranged on both sides thereof are connected to the coupling member 25. Since they are pivotally supported by the pivot shaft 24 at the central portion, the rollers 23 attached to the support frames 21 and 21 ′ before and after the pivot position are in contact with the guide surfaces 32 of the guide rails 30 respectively. As shown, the doors 35 are supported by the rollers 23. Accordingly, the rollers 23 on both sides of the carrier 20 that are arranged with the moving space 33 interposed between the guide rail 30 and the guide surface 32 are supported on the left and right sides of the guide surface 32, and the coupling member 25 is moved when traveling. Since the load acting through the pivot shaft 24 acts on the support frames 21 and 21 ′ on both sides and is not concentrated on some of the rollers 23, the load acts equally on each roller 23. The vehicle can be driven without receiving a large frictional resistance.

  As a result, since all the rollers 23 roll on the guide surface 32 of the guide rail 30 under the same conditions, it is possible to run lightly and smoothly open and close the door 35 with little power. Moreover, since such a state is exhibited, neither the roller 23 nor the guide rail 30 is damaged, and long-term use can be expected.

  In the above description, the support frame of the carrier has been described with the metal plate bent, but if the left and right support frames are configured to be rotatable about the pivot shaft, Needless to say, the shape structure can be changed.
