DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for storing long materials in a pallet and storing them in a three-dimensional manner. The present invention relates to a storage material detection device capable of performing the following.

[0002]

2. Description of the Related Art Conventionally, as a method of storing and storing a work material such as a cutting machine in a three-dimensional manner as a storage material, as shown in FIG. There is a storage material storage device 1 in which a rack 5 is arranged. Generally, one or a plurality of long materials 7 are stored and carried out by a crane device 9 on the rack 5.

[0003]

By the way, in such a storage material storage device 1, in order to store many kinds of materials 7 because the stock amount of the materials 7 of the rack 3 is too small.
It has been difficult to perform reasonable storage management, for example, the storage efficiency is low, and in the case of a round bar, if an earthquake or the like occurs, the storage unit falls from the rack 5 if an earthquake or the like occurs.

[0004]

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, the present invention provides an arm at upper and lower positions of a pallet capable of storing a plurality of long materials in parallel in the width direction. The U-shaped column provided is provided so as to be movable in the longitudinal direction of the pallet, and a position detector for detecting the moving position of the U-shaped column in the longitudinal direction is provided, corresponding to the parallel position of the material. A plurality of sensors for detecting the presence or absence of the material are provided on the arm portion, and when the U-shaped column moves in the longitudinal direction, material detection of each of the sensors and position detection by the position detector are performed. And detects the parallel position and length of a plurality of materials stored in parallel on the basis of.

[0005]

Embodiments of the present invention will be described below in detail with reference to the drawings.

As shown in FIG. 2, a large number of arm-shaped racks 13 are vertically mounted on both sides of a pallet table 11 in the same manner as in a conventional storage material storage device. For example, pallets 15 of No. 1 to No. 5 are arranged respectively. These pallets 15
Is, for example, No. 1. For No.2, No.3, a 7-row pallet as shown in FIG. 3A is used, and for No.4, No.5, a 4-row pallet as shown in FIG. There is a way to keep it. 3C shows a three-row pallet, FIG. 3D shows a two-row pallet, and FIG. 3E shows a one-row pallet.

Further, a bar code is attached to each of the No. 1 to No. 5 pallets 15, and the number of columns of each pallet 15 can be read and detected by using this bar code.

As shown in FIG. 4, the pallet 15 has a plurality of fences 19 provided at appropriate intervals in a longitudinal direction in a frame 17 which is long in the longitudinal direction with respect to the width direction and formed in a rectangular shape. The fence 19 is formed as thin as possible so as not to hinder the detection of the long material 7. Short materials can be effectively stored in the pallet 15.

As shown in FIG. 1, the U-shaped column 21 extends in the width direction of the pallet 15 and has arms 23 located above and below the pallet 15.
Are provided so as to be movable in the longitudinal direction (the direction perpendicular to the paper surface in FIG. 1). A plurality of detectors, in this embodiment, seven sets of light-receiving and light-emitting photoelectric sensors 25 and 27 are vertically arranged on the arm 23 in accordance with the number of rows of the materials 7 stored in parallel with the pallet 15 in this embodiment. They are mounted facing each other.

In the U-shaped column 21, a column moving portion 29 is formed in the space inside the U-shaped column 21 and the pallet 15 in this embodiment. The column moving section 29 includes a guide member 31 having both ends fixed to the pallet table 11 and extending in the longitudinal direction, two slide rails 33 mounted on the guide member 31, and one rack 35. And two slide guides 37 mounted on the column 21 and engaged with the slide rails 33.
And a pinion gear 41 and an encoder 39 that mesh with the rack 35.

The column moving section 29 moves the U-shaped column 21 along the rack 35 in the longitudinal direction of the pallet 15 by rotating the pinion gear 41 by a drive motor (not shown). The presence / absence of the storage material 7 is detected by the light emitting side photoelectric sensors 25 and 27. At that time, the encoder 39 is a position detector that detects the movement position of the U-shaped column 21 by the rotation of the pinion gear 41.

In the above configuration, the U-shaped column 21 is used to detect the presence and length of the material 7 supported in parallel on the pallet 15 supported near the long end in the longitudinal direction by the rack 3. By moving in the longitudinal direction between the racks 3 supporting the pallets 15, the sensors 25 and 27 detect whether or not the material 7 is present in the corresponding row.

Then, the movement position of the U-shaped column 21 is detected by the position detector, and based on the position where one end of the material 7 is detected by the sensors 25 and 27 and the position where the other end is detected, The length of each material 7 can be detected.

That is, it is possible to detect the parallel positions and lengths of a plurality of materials 7 stored in parallel on the pallet 15.

[0015] As shown in FIG.
A pair of photoelectric sensors 25 and 27 are provided on one arm 23, and the photoelectric sensors 25 and 27 are scanned in the width direction Q and in the longitudinal direction P to store the storage material 7 in the pallet 15. May be detected.

It should be noted that the present invention is not limited to the above embodiment, but can be implemented in other modes by appropriate design changes.
It may be mounted on the outside of the character column 21 instead of the inside.

[0017]

As will be understood from the above description of the embodiments, in short, the present invention provides a plurality of long materials (7).
U-shaped column (21) having arms at upper and lower positions of a pallet (15) that can be stored in parallel in the width direction
Are provided so as to be movable in the longitudinal direction of the pallet (15), and a position detector for detecting the position of the U-shaped column (21) in the longitudinal direction is provided. A plurality of sensors for detecting the presence or absence of the material (7) corresponding to the position are provided on the arm portion, and the material detection of each of the sensors when the U-shaped column (21) moves in the longitudinal direction. Since it is configured to detect the parallel position and length of a plurality of materials stored in parallel based on the position detection by the position detector and
The arrangement position and the length of a plurality of materials stored in parallel on the pallet 15 can be detected.
