[Detailed Description of the Invention] The present invention is a transportation equipment f which is made up of a rail device and a trolley device that can travel on a fixed route guided by the rail device.
This is related to this, and its purpose is to prevent the magnetic field of the code magnet for information reading provided in one of the trolley devices from being affected even if magnetically charged luggage is stored in the luggage storage section of the trolley device. First, it is an object of the present invention to provide a conveying device that can accurately read information such as the position of the traveling vehicle on the route and the destination.

An embodiment of the present invention will be described below based on the drawings.

This conveyance device attempts to detect the position of a trolley device as information using a magnetic cord in order to transfer the trolley device between parallel rail devices.

In the figure, reference numeral 1 denotes a rail device having a C-shaped cross section, which is installed with its open portion above, and forms an upward facing surface 1a, both side surfaces 1b, and a pair of left and right downward facing surfaces 1c.

A pair of power supply rails 2, a signal rail 3, and a lug gear 4 are laid on the upward surface 1a in the length direction of the rails.

Reference numeral 5 denotes a trolley device that can travel on a fixed path 6 guided by the rail device 1C, and includes a main body f2E7, and idle wheels 8 that are pivotally supported on one end side of this main body 7 and can be moved on the upward surface 1c. , an idling wheel 9 which is pivotally supported on the other end side C of the main body 7 and can be moved on the downward facing surface 1c, and a lateral slip prevention device which is attached to the shafts of both idling wheels 8 and 9 and which can be moved on the side surface 1b. The motor 1 attached to the lower part of the other end of the main body 7
2, a friction drive wheel 13 attached to the drive shaft from the motor 12 and movable on the upward surface 1a, a pinion gear 14 attached to the drive shaft and able to engage with the rack carrier 4, and a collector. 15, a slider 16, and a luggage storage container 17.
It is configured to make contact with the top.

One is another rail device installed in parallel with the rail device 1f, and a portion of the parallel circuit formed by these two rail devices 1°IAj is provided with adjacent missing rails 18.

Reference numeral 19 denotes a movable rail provided in this cutout rail portion 18, which can be selectively connected to both rail devices 1 and 1A.

In other words, the movable rail 19 is configured to be movable in the horizontal direction intersecting the direction of the path by being guided by the pedestal 20 provided with the missing rail portion 18I. A disk 23 rotatable around a vertical axis 22 that extends over a drive shaft 211, a roller 24 pivotally attached to the surface structure position f of this disk 23, and a roller 24 that allows insertion of this roller 24 and It is possible to adopt a configuration with a pair of guide bodies 25 installed on the underside of the movable rail 19 to allow sliding in the path direction, and further set the disc 23 to rotate intermittently by 180 degrees. becomes.

The movable rail 19f and a roller device 26 are provided which guide the trolley device 5 transferred onto the movable rail 19 while pressing it in a horizontal direction t perpendicular to the traveling direction.

That is, a plurality of rollers 29 are disposed in the running direction (a plurality of rollers 29 are disposed on the upper end of a plate-shaped body 27 that stands up from one side outer surface of the movable rail 19 via a vertical shaft 28, and these rollers 29 are Its position is set so that it comes into contact with one side of the imported trolley device 5 and presses it against the side opposite to the abutting side.

Further, the movable rail 19 is provided with a detection body 31 that reads a code magnet 30 provided on the trolley device 5.

One cord magnet 30 is provided on one side of the trolley device 5 in a plurality of rows so that the position can be adjusted, and the mutual positional relationship f of these code magnets 30 allows the accurate position of the trolley device 5 on the travel path 6 to be determined. is readable.

The detection body 31 is made of, for example, a reed switch attached to the plate-like plate 127f, and after reading the code magnet 30, the read signal is passed from the signal rail 3 of the movable rail 19 to the slider 16 to send a stop signal to the motor 12. Alternatively, the read signal may be used to convert both feed rails 2 to the same polarity.

Now, numeral 32 in FIG. 4 is a ferromagnetic tape, which is attached ##3 inside the baggage storage section 17 of the code magnet 30, and the storage section 171 stores magnetic baggage, such as magnetic tape. Even if the cord magnet 30 is exposed to the cord magnet 30, the cord magnet 30 is prevented from being affected by the magnetism of the baggage.

Instead of this ferromagnetic tape, as shown in FIG. 5, a magnetic shielding plate 33 made of a ferromagnetic material is provided, which is a single plate extending from the inside of the baggage storage section 17 of the cord magnet 30 to the bottom wall of the storage section 17. It's okay if you can get it.

Furthermore, it goes without saying that a magnetic tape 34 may be attached to the back surface 30a of the code magnet 30 as shown in FIG. 6.

In addition, 30b (J magnet, 30c ('')
30b is a protective resin, and 30d is a guide for guiding the movement of the code magnet 30.

Below, the side rail devices installed in parallel 1. Trolley device 5 between IAs
transfer work between stations.

First, as shown by the solid line 1 in FIG. 2, the movable rail 19 is connected to the rail device 11 on which the bogie device 5 travels.

The trolley device 5 moves from this rail device 1 to the movable rail 19r.
The code magnet 30 then moves to the detection object (as shown in FIG. 3H faces each other.

This opposing state is maintained at a constant interval because the trolley device 5 is pressed against the roller 291, and moreover, between the cord magnet 30 and the magnetic baggage (this is the ferromagnetic magnetic shielding members 33 to 34). is interposed, so the magnetic edge of the baggage is connected to the magnetic shielding members 32 to 3.
41 is blocked, and its influence no longer affects one magnetic field line emitted from the code magnet 30, so the detection object 31'
Due to this detection, the trolley device 5 stops within the movable rail 19, and the detection object 31
The detection signal f drives the vertical shaft 21 and rotates the disk 23 by 180 degrees.

As a result, the movable rail 19 moves while being guided by the pedestal 20t, and connects to another rail device as shown by the solid line 1 in FIG.

During the movement of the movable rail 19, the trolley device 5 is held in a pressed state by the rollers 29, so that it moves integrally with the movable rail 19 without wobbling.

After that, the trolley device 5 transfers to another rail device 11,
Run.

Note that it is also possible to transfer from another rail device 1A to the rail device 1 by performing a reverse operation to that described above.

As described in detail above, in the conveyance device according to the present invention, the conveyance device is provided with a trolley device that can travel on a fixed route guided by a rail device, and this trolley device has a luggage storage section. When the rail devices are arranged in parallel, a missing rail portion is formed in the juxtaposed portion of f, and in this missing rail portion,
A movable rail that can be selectively connected to both rail devices is provided, a detector is provided for the movable rail, and a code magnet is provided on the trolley device to cause the detector to respond in response to the detector. The movable rail is configured to move by detecting the code magnet with a detection body, and a magnetic shielding member is interposed between the code magnet and the luggage loaded in the luggage storage section. , the magnetic force detected by the object to be detected (the magnetic force due only to the code magnet), and even if the baggage is magnetic, the magnetic field (1) is blocked by the magnetic shielding member, so the magnetic field of the code magnet is ("It does not affect.

Therefore, there is no need to attach a code magnet to a magnetic baggage at a separate location, and information about the trolley device can be detected by exactly one detector.

In particular, according to the present invention, since the movable rail on which the bogie device is transferred is a single-track type, the structure can be simplified compared to a double-track type.

In such a single-track system, there is a risk that the moving track of the movable rail may reach the track of one of the movable rails and fall off due to malfunction, but according to the present invention, a movable rail detector is provided and a cord magnet is installed. Since the magnetic sheet is used to separate the baggage, detection is only performed after transferring to the trolley device.Therefore, there is no false detection at all, and as mentioned above, the magnetic sheet does not give any false information. Therefore, it is possible to always carry out accurate transfer of carts.
