Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cylindrical article storage device for storing a cylindrical article such as roll paper in an automatic warehouse, and further to a storage device for transferring the cylindrical article to a conveying means. The present invention relates to a cylindrical article storage device provided with a storage device that stores a transported article by rolling from a shelf surface of a shelf.

[0002]

2. Description of the Related Art Conventionally, in a three-dimensional automatic warehouse, there is known a roll paper storage device in which roll paper is rolled from the back of the shelf to be transferred to a storage position and is transferred to the shelf by a fork or the like. However, when the roll paper rolls from the shelf side in the running direction of the stacker crane and is transferred to the shelf with a fork etc., in order to secure a space for inserting the fork on the lower surface of the roll paper, the roll paper is mounted on the cart. A pair of lifters have been used to lift. This type has a problem that the entire apparatus is complicated and the cost is increased because a pair of lifters is provided on the carriage.

As another type, the carriage is provided with a pair of roll receivers, and when the roll paper is transferred from the floor to the carriage, the roll receivers are rotated and the rear roll receiver is used.
It is known that the rolling of the roll is stopped and the roll paper is placed on the roll receiver.

A conventional example in which a carriage is provided with a pair of roll receivers will be described below with reference to FIG.

In the figure, a trolley 21 is rotatably connected to a fixed guide body 22 having a horizontal guide surface 22a which is the same as the floor surface 34, and a hinge 27 to the fixed guide body 22, and a pair of roll receivers 23a, A roll receiver 24 having a U-shaped cross section, a frame 25 on which the roll receiver 24 is placed, a power cylinder 26 for tilting the roll receiver 24 that tilts the roll receiver 24, and a motor 28. A traveling wheel 29 that reciprocates the carriage 1 on the rail 30 between the roll paper storage position and the transfer position of the transport device is provided.

In this conventional apparatus, when the roll paper 31 is placed on the carriage 21, the carriage 21 is stopped at the position shown by the solid line in FIG. 3, and the roll receiver 24 is the power cylinder 26 for tilting the roll receiver. As a result, it is rotated about the hinge 27, and the leading end of the one roll receiver 23b is positioned so as to project above the floor surface 34.

When the roll paper 31 is rolled from the floor surface 34 and transferred onto the carriage 21 in this state, the roll paper 31 collides with the roll receiver 23b and stops. Next, the power cylinder 26 for tilting the roll receiver operates to rotate the roll receiver 24 in a horizontal state, and the roll paper 31 receives the pair of roll receivers 23.
Support between a and 23b. Next, the motor 28 is actuated, the carriage 21 is moved to the delivery position of the transport device (not shown) indicated by the two-dot diagonal line in FIG. 3, and the fork of the transport device is inserted between the roll receivers 23a and 23b to transport the transport device. Thus, the roll paper 31 is transferred to the roll receiver 33 of the shelf 32. When the roll paper 31 is unloaded, the roll paper 31 is unloaded by performing operations in the reverse order of the above-described operations.

[0008]

The above-mentioned conventional device is
Since the roll paper is structured to stop by the roll receiver during the roll paper storage operation, the roll receiver and the power cylinder for tilting the roll receiver have a large impact force when the roll paper collides with the roll receiver. Will join.
Therefore, it is necessary to provide these components with strength that can withstand the impact force caused by the collision of the roll paper, and it has been dealt with by using high-strength materials and increasing the size of the apparatus. Therefore, the cost of the apparatus increases, and there has been a demand for the development of a simple and low-cost storage apparatus.

[0009]

In order to solve the above-mentioned problems, the present invention has a transfer means that expands and contracts in the lengthwise direction of a cylindrical conveyed article and stores the conveyed article in a shelf, In a cylindrical object storage device in an automated warehouse equipped with an warehousing device for delivering a cylindrical object to a carrier means between a warehousing position and a carrier means, the warehousing device relatively opens and closes in a horizontal direction to form a cylindrical carrier. It is a cylindrical object storage device in an automatic warehouse, characterized in that it has a pair of load receiving rollers on which an object is placed.

In the storage device of the present invention, the cylindrical transfer object is supported by the load receiving roller which is relatively contacted and separated in the horizontal direction and is opened and closed, and is transferred from the storage position to the delivery position. At the warehousing position, the loading operation is performed with the load receiving roller closed, and at the delivery position, the fork of the transporting means is inserted between the load receiving rollers with the load receiving roller open, so that the transfer operation of the cylindrical transported object is performed. Is done. As described above, according to the present invention, since the goods are transferred from the warehousing device to the conveying means by the horizontal movement operation of the warehousing roller, the warehousing device of the warehousing device can be operated simply and easily. Therefore, it is possible to provide an inexpensive storage device in which no failure occurs.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION The invention according to claim 1 of the present invention has a transfer means that expands and contracts in the lengthwise direction of a cylindrical conveyed product, and stores the conveyed product in a shelf, and a storage position. In a cylindrical object storage device in an automated warehouse equipped with a warehousing device that transfers a cylindrical object to the conveyor means between the container and the conveyor means, the warehousing device relatively moves horizontally to open and close to transfer the cylindrical objects. The storage device has a pair of load receiving rollers to be mounted, and the storage device supports the cylindrical transported object by the load receiving rollers that relatively open and close in the horizontal direction to transfer the transported object. Since it is structured so as to be transferred at the time, the load receiving means, which is the load receiving roller of the storage device, is configured not to perform an unreasonable operation at the time of storage and at the time of delivery, so that no trouble occurs and the cost is low. A storage device It can have an effect.
