Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is applicable to bending and straight traveling. It is possible to turn and raise/lower by means of an endlessly connected running cart and treadle, and is connected to a conveying device that forms a complicated running path.

[Conventional technology]

A transport device equipped with a transport platform with a flat surface, such as a so-called moving walkway on which a person can ride, uses an endless chain or belt with a required travel distance, and a constant-confluence treadle is attached adjacent to this chain. A subrocket wheel or a pulley on which the chain or belt is attached is driven by a drive device in a so-called centralized drive system.

[Problem to be solved by the invention]

According to this concentrated drive system, tension is directly applied to the chain or belt by the drive, so the longer the moving distance, the stronger the tensile strength. For this reason, there is a limit to the allowable travel distance in view of the strength and structure of the chains and belts, and conventionally, each chain or belt can move up to 200 m, making it impossible to move them too long.

Furthermore, the chain belt can be bent in the forward and backward directions, that is, in the vertical direction in a straight line in the driving direction of the chain belt. I can't. Therefore, it is necessary to install multiple linear conveyance devices connected to each other where the running path bends or curves, and it is impossible to install it where the running path is bent many times and the angles are different. Therefore, while conventional conveyance devices such as moving walkways only have straight lines, the present invention makes it possible to arbitrarily select and arrange bends, curves, and their angles, as well as elevation angles. [Means for solving the problem] A plurality of linear motors are distributed along a loop-shaped traveling path, and traveling bogies that are distributed and driven by the linear motors are arranged in an endless manner on the traveling path, and the traveling path is Adjacent running bogies are movably connected so as to follow the bending and straight-travel shape, and the treads provided on each running bogie are slid along the curve of the running path to follow the bending of the running bogie, and the treads are movable to follow the bending of the running bogie in the curve of the running path. On the other hand, it is movably provided using guide rails so that it is always kept horizontal.

〔Example〕

The conveying device of the present invention will be described below as an embodiment of a moving walkway.

In the figure, reference numeral 1 denotes a running path, and as long as it is loop-shaped, its shape is not limited and can be made into various shapes as shown in FIG. 4. This traveling path 1 is constructed by installing a number of traveling rail mounting bases 2 in a predetermined direction in the direction of movement in a frame (not shown) fixed to a predetermined height above the floor surface or in a groove formed by lowering the floor surface. The two running rails 3, 3 are arranged and fixed to this running rail mounting base 2 in parallel with each other. A plurality of linear motors 4 (primary side) are distributed and installed at a plurality of locations on the running path 1. The primary side of this linear motor is disposed at appropriate intervals so that the traveling carriage guided along the traveling path can be smoothly driven. A plurality of running carts 5 are connected to each other on the running path 1 so that their front and rear ends in the running direction can bend and swing.

The traveling bogie 5 has a reaction plate 51 vertically disposed at the center of the lower part of the bogie body 50 along the running direction of the bogie, and has a reaction plate 51 on either the front or the rear of the bogie body 50 in the running direction (the latter example in the figure). Boss portions 52a are provided at the top and bottom, respectively.
．． 52a are provided in a protruding manner, and boss portions 52a. A shaft 53 is vertically supported between the shafts 52a, and the shaft 53 supports the bogie stand frame 54 so as to be able to swing in the left-right direction. horizontal roller 55.5
5 are supported opposite each other, and the horizontal rollers 55.55 are arranged so as to come into contact with the inner surfaces of two running wheels 3.3 arranged in parallel.

The bogie frame 54 has a U-shape when viewed from above, and has a boss portion 54a provided with a bearing 54d protruding from the center thereof. Both left and right frame pieces 5 4 protrude from the boss portion 54a to both sides
Traveling wheels 56, 56 are supported by the wheels 56, 54c facing each other, and the traveling wheels 56, 56 are placed on the traveling rails 3, 3 in a movable manner to support the load of the traveling truck.

Also, the frame pieces 54b opposite to the U-shaped bogie frame 540. 54c is open, and a spherical bearing 57 is disposed as a self-aligning device directly below the boss portion 54a, and the spherical bearing 57 is secured by penetrating through the shaft 53 and is protruded from the spherical bearing 57. A connecting rod 58 is fixed to a part of the front traveling truck. This connecting rod 58 is in the form of a bolt, and the tip of the rod is inserted into a part of the forward running bogie, so that it is adjustable and supported between the front and rear running bogies which are connected adjacently by a fixing nut 59. ．． Therefore, one running bogie 5 is equipped with one bogie body 50, and a bogie frame 54 and a spherical bearing 57 are protruded from the rear end of this bogie body 50, and the spherical bearing 57 is connected between the front and rear running bogies. 57, the running wheels 56, 56 at the inter-bogie connection position movably support half of the load of the front and rear running bogies, and the horizontal rollers 55 and 55 protrude laterally at the same position. The traveling bogie 5 is guided by the traveling rail 3 and runs safely. In the curved section, the bogie frame 54 swings and the spherical bearing 5
7. Which action is used to reduce running resistance? Note that when traveling on a curved section of the traveling rail, the allowable swing range of the bogie frame is guided so that the traveling wheels do not come off the traveling rail even if the bogie frame 54 swings left and right with respect to the bogie body 50. etc. (not shown). In this way, a bogie frame is provided at the connecting part between the bogie bodies that are connected adjacently in the front and rear, so that the bogie body can run with reduced running resistance even on curved roads.The upper part of the bogie body of each traveling bogie has a top surface. A flat tread 6 is provided. This tread 6 is mounted on the top of the truck body 50 with tread support columns 60.6 in the front and back of the running direction, respectively.
1 is provided protrudingly, and the upper end of one of the tread support pillars 60 and a bracket 62 protruding from the bottom surface of the tread plate are pivotally connected by a support shaft 63,
The tread plate 6 is supported so as to be tiltable around this support shaft 63, and a cushion material 64 is provided protruding from the upper end of the other tread support column 61, and the bottom surface of the tread plate is in contact with this cushion material 64 to run on the tread plate 6. The footboard 6 is kept horizontal parallel to the posture of the truck, that is, when it is on a flat road, and guide rollers 65 and 65 are installed on the brackets 66 on both sides opposite to the support shaft.
．． This guide roller 65 is supported by guide rails 67 and 67, which are installed vertically through the guide rollers 66 and are arranged parallel to the outside of the travel rail and at an angle that matches the inclination of the travel path on the slope. The footboard 6 is made to remain horizontal even if the truck follows the slope of the traveling path and slopes. 68 is a safety cover that prevents gaps from forming between adjacent treads when the traveling trolley is tilted and the treads remain horizontal, thereby preventing feet from getting stuck between the adjacent treads. It is something to do. Further, even if this tread plate 6 is bent at the connecting part of the traveling truck, no gap will be created in the connecting part of the tread plate. For example, as shown in FIG. 3, one end is made to protrude in an arc shape, and the other end is made into a concave shape into which the protruding arc fits, so that the protruding arc surface 6a and the concave surface 6b fit into each other, and The treads 6.6 slide against each other along this arcuate surface, allowing a smooth transition from the straight section to the curved section of the travel path l. A large number of traveling carts 5 configured as described above are arranged adjacently in the front and rear of the traveling direction, and a spherical bearing 57 is used to connect the adjacent traveling carts 5, 5.
and are connected via a connecting rod 58 with a required gap.
At this time, the upper tread plates 6 and 6 are also adjacent to each other so that the concave groove and the protruding arc fit into each other. At this time, the front and rear traveling carts 5, 5 can swing laterally relative to each other using spherical bearings,
In addition, a bogie frame 54 equipped with running wheels is disposed at the running bogie connection part, and the load applied to the front and rear running bogies is supported, and at the curved line portion of the running rail 3, this bogie frame 54 responds to the radius of the curve. The treads can swing freely within the allowable swinging range, and the arcuate surfaces 6a of the treads can also be aligned with each other.
．． 6b, they slide against each other, and the running wheels always follow the running rails, making stable running possible.

When the running route is inclined, for example, when a part of the running route is inclined, when an escalator is used, or when the running route is arranged like a spiral staircase, the slope is adjusted according to the inclination angle of the running route. The guide rail 67 is arranged parallel to the running rail, so that the running path can be made not only a horizontal straight curved road but also an inclined straight road. The treadle should always be kept horizontal or close to horizontal, even on inclined bends or spiral paths. [Effects of the Invention] The conveying device of the present invention can arbitrarily select the shape of the traveling path, and if it is placed on a single moving tread strip, it can be used on straight roads, curved roads, etc.
Ramp, spiral path. You can move AI circuits without changing,
For this reason, buildings and street trees. It has the advantage of being able to create a travel path that bypasses existing equipment such as fire hydrants.
