Description

Description: TECHNICAL FIELD The present invention relates to a mobile storage device in which a mobile storage line is provided in front of a fixed storage line to improve storage efficiency. is there.

[Prior Art] As a mobile storage device of this type, a plurality of mobile storage lines composed of a plurality of mobile storage lines are provided on the front side of a fixed storage line that is adjacent to each other in the left-right direction. It is known that they are arranged in rows and arranged so that the mobile storage can be moved in the left-right direction to open the front of the desired storage.

By the way, in the case of this type, it is necessary to stop the mobile storage at the position moved to the rightmost or the position moved to the leftmost. Therefore, when the position is reached or approached, the power supply to the driving motor is stopped and the movable storage at the end position is locked by the stopper.

Thus, the conventional stopper is provided in a wall-like shape at the end of the rail, and the side surface of the mobile storage is collided with the wall-shaped stopper via a cushioning material such as rubber. .

[Problems to be Solved by the Invention] However, in such a case, it is necessary to provide a relatively tall and sturdy stopper at the end of the rail. Therefore, the horizontal dimension of the rail portion must be made larger than the horizontal dimension of the moving area of the mobile storage, and the space at the left and right ends cannot be effectively used.

Further, this type of mobile storage device is often installed, for example, in a state where one end side of the mobile storage device is not close to the wall and is open. In this case, it is often the case that a person crosses one end of the rail diagonally while moving the mobile storage to the other end side. At that time, if a stopper is provided in a wall shape at the end of the rail, it is likely to be a hindrance to traffic and is dangerous.

Furthermore, the center of gravity of this type of mobile storage is at a relatively high position, so if the front end of the mobile storage on the bottom of the mobile storage is locked by a stopper provided at the end of a rail laid on the floor, it will move. The entire storage will stop in a stumbled manner. Therefore, if the traveling speed of the mobile storage cabinet just before the locking is not sufficiently reduced, the wheel on the rear end side in the traveling direction may temporarily rise from the rail, and the wheel falls again on the rail. In that case, a large amount of noise is generated and the stored items collapse.

The present invention aims to solve such problems.

[Means for Solving the Problems] The present invention is configured as follows in order to achieve the above objects.

That is, the mobile storage device according to the present invention has substantially the same width dimension as the fixed storages on the front side of the fixed storages row in which three or more fixed storages are adjacent in the left-right direction. Arrange a row of mobile storage cabinets by arranging the mobile storage cabinets one less than the number of fixed storage cabinets in the left-right direction, and move the mobile storage cabinets on the rails laid in the left-right direction to move to the desired storage. In a mobile storage device in which the front of the storage can be opened, a rail main body supporting the wheels of the mobile storage stored in the center of a channel-shaped base that opens upward, and a rail main body. And a concave groove formed between the base and the opening edge of the base, and the mobile storage cabinets collide with each other when the mobile storage cabinets are packed on the rightmost side or the leftmost side. Near the boundary position where A space that directly contacts the rail main body is provided, and a stopper housed so as to be completely accommodated in the groove is fixed to the spacer, and the lower surface of the mobile storage is loosely fitted in the groove. The projection is provided so as to project, and the projection is brought into contact with the stopper to lock the moving storage just before the moving storage finishes passing over the stopper.

[Operation] With such a configuration, the stopper does not exist at the end of the rail. Therefore, there is no restriction that the horizontal dimension of the rail portion needs to be larger than the horizontal dimension of the moving area of the mobile storage. Since the wheels are located inward of the sides of the mobile storage cabinet, in extreme cases, the horizontal dimensions of the rail can be set smaller than the horizontal dimensions of the mobile storage cabinet's movement area. become.

Since this stopper is accommodated in the groove of the rail and does not project upward from the opening end surface of the groove, the user may trip over when using the storage. Absent.

Moreover, by disposing the stopper near the boundary position described above,
Just before the mobile storage finishes passing over the stopper, the projection abuts on the stopper so that the mobile storage can be locked. The inertial force acting on the storage cabinet works as a force for pressing the mobile storage cabinet downward. Therefore, it is possible to reliably prevent the wheels of the mobile storage from rising from the rails.

Moreover, the stopper 109 is disposed in the vicinity of the boundary position described above, moves stocker 2 ₁ to 2 ₆ abuts the mobile depot the projection 21 to the stopper 109 just before finishes passing over the stopper 109 Since 2 ₁ , 2 ₃ , 2 ₄ , and 2 ₆ can be locked, when the projection 21 comes into contact with the stopper 109, the movable storage cabinets 2 ₁ , 2 ₃ , 2 ₄ , and 2 ₆ are stored. The acting inertial force acts as a force for pressing the mobile storage boxes 2 ₁ , 2 ₃ , 2 ₄ , and ₂₆ downward. That is, each mobile storage cabinet 2 ₁ , 2 ₃ , 2 ₄ , 2 ₆
The center of gravity of is located far above the position where the stopper 109 is provided, and when the projection 21 contacts the stopper 109, the center of gravity passes over the stopper 109 and is located forward in the traveling direction. Therefore, the mobile storage boxes 2 ₁ , 2 ₃ , 2 ₄ ,
The inertial force acting on ₂₆ acts on the mobile storages 2 ₁ , 2 ₃ , 2 ₄ , and ₂₆ with the stopper 109 as a fulcrum to rotate forward in the traveling direction. The wheels 91 ₁ , 91 ₂ of ₁ , 2 ₃ , 2 ₄ , 2 ₆ are pressed against the rail body 105. Therefore, it is possible to reliably eliminate the phenomenon that the wheels of the mobile storage are temporarily lifted from the rails.
It is possible to eliminate the problems that a large noise is generated and the stored items are disturbed by an impact.

In addition, although the electric moving storage device is described in the above embodiments, the present invention can be applied to a manual moving storage device. In that case, since it is not necessary to switch the limit switch, it is possible to make the horizontal dimension of the rail smaller than the horizontal dimension of the moving area of the mobile storage.

Further, the number of stations of the fixed storage or the mobile storage, or the number of rows of the mobile storage is not limited to those of the above-described embodiment, and may be various without departing from the gist of the present invention. Deformation is possible.

EFFECTS OF THE INVENTION Since the present invention has the above-described structure, it is not necessary to provide a sturdy and tall wall-shaped stopper at the end of the rule. Therefore, it is possible to solve the problem that the stopper becomes an obstacle and is dangerous, and at the same time, the rail unit can be shortened as much as possible to effectively use the space. In particular, according to the present invention, since the stopper is mounted in the groove so that the entire stopper is completely contained in the groove, the stopper does not project in the middle of the rail unit, and the fixed storage cabinet is provided. It is possible to smoothly take items in and out of the mobile storage.

Moreover, since the projection of the mobile storage cabinet abuts the stopper just before the mobile storage cabinet has finished passing over the stopper, the mobile storage cabinet can be neglected. It is possible to reliably eliminate the problem that the wheels temporarily float up from the rails, and it is possible to effectively prevent noise generation and unreasonable collapse of loads.
