Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a three-dimensional warehouse for storing roll paper that allows for efficient loading and unloading.

[Prior art]

In general, the main functions required of multi-story warehouses are storage capacity, which allows storage of many items in a small space, and management of storing a wide variety of items and transporting desired items or storing them in designated locations. In addition, it is easy to carry in and out, allowing for quick loading and unloading and minimizing play time.

In the case of a multi-story warehouse for storing roll paper with a shaft (core rod) wound up by a paper machine, the types are distinguished depending on the quality of the paper, but the external shape and dimensions of the roll paper wound into a roll shape Since this is constant, the quality of the warehouse is determined by how efficiently the loading and unloading is carried out.

A conventional three-dimensional warehouse for storing roll paper is shown in FIG. 2 and will be described. In the figure, the trolley 2 carrying the roll paper 5 stops right below the traverser 3, and the crane 4 travels into the traverser 3 and pulls up the roll paper mounted on the trolley 2. Next, after hoisting it up to a predetermined height, the crane 4 travels on the row of storage shelves and stops at the position where it should be stored.
The empty cart 2 travels on the loading/unloading path 1 and performs the next job. The figure just shows the situation at that time.

In this conventional three-dimensional warehouse for storing roll paper,
It has the following drawbacks in terms of ease of loading and unloading.

As an example of loading and unloading, if you want to use the empty trolley 2 to carry out a different type of roll paper stored in an adjacent storage shelf as shown in the figure, you must do it as follows. Must be.

That is, the crane 4 now lifts up the roll paper loaded on the trolley 2, carries it to a predetermined storage shelf, and stores the roll paper. During this time, the cart 2 moves to the next row of storage shelves and waits. Next, the crane 4 that has been stored returns to the inside of the traverser 3, and is moved together with the traverser 3 to an adjacent storage shelf. Therefore, the crane 4 moves to a predetermined position along the storage shelf row, picks up the desired roll paper stored therein, returns to the inside of the traverser 3, and then unloads the roll paper to the waiting trolley. Installed on 2.

In this way, the work of the crane 4 is to run from the traverser 3 and store the roll paper → return to the traverser 3 → move to the next row of storage shelves → travel along the row of storage shelves to a predetermined location → A series of operations is carried out: pulling up the stored desired roll paper → returning it to the traverser 3 → loading it onto the trolley 2,
During this time, the trolley 2 has to wait with idle time.

In addition, when multiple trolleys 2 are in operation during loading and unloading, there are multiple trolleys 2 for one crane, which further increases idle time of the trolleys 2, resulting in poor loading and unloading performance. It was hot.

[Purpose of the invention]

The present invention has been made in order to solve the above-mentioned conventional drawbacks, and aims to provide a multi-dimensional warehouse for storing roll paper in which carts and cranes can be efficiently matched and the ease of loading and unloading is improved. .

[Summary of the invention]

That is, the present invention provides a temporary storage area that serves as a kind of relay while the cart is being stored in the storage shelf, so that the correspondence between the cart and the crane can be efficiently carried out. Located above the row of storage shelves, a rail for running the crane is provided, and located in front of the row of storage shelves, a loading/unloading path is provided across the row of storage shelves, and directly above the loading/unloading path. A rail for running the traverser will be installed at the top, and a temporary storage area will be set up at a height that the trolleys loaded with paper rolls can pass through directly above the loading and unloading path. It is also characterized by having a function that allows roll paper to be placed thereon.

[Embodiments of the invention]

An embodiment of the present invention will be described in detail below. In Figure 1 (side view), loading and unloading path 1
Rail 7 for the traverser 3 to run directly above the
is provided. Reference numeral 8 denotes a temporary storage area, which is located directly above the loading and unloading path 1, and is set at a height such that the trolley 2 carrying the roll paper 5 can pass through it.

As shown in FIG.
is integrally connected to an L-shaped arm 11, and is configured to be opened and closed by a cylinder 14 around a pin 12 as shown by the arrows. In addition, 10 is a seat for receiving the roll paper shaft, 13 is an arm 11 and a cylinder 1.
A connecting pin 15 connects the rod 4 and a beam 15. FIG. 7 shows a state in which the roll paper 5 is placed in a temporary storage area (plan view). When the roll paper is passed through, the support beam 9 is rotated upward by the cylinder 14, as shown by the imaginary line in FIG.

As shown in FIG. 3 (front view), storage shelf row 18
A traveling rail 17 for the crane 4 is provided above the storage shelf row 18. Further, as shown in FIG. 4 (plan view), in this embodiment, the temporary storage areas 8 are provided at four locations corresponding to the rows of storage shelves. In the figure, reference numeral 17 indicates a crane traveling rail provided along the storage shelf row, and 7 indicates a traverser traveling rail provided across the storage shelf row.

[Action of the invention]

The operation of this embodiment configured as above will be explained next.

Referring to FIG. 1, first, the case where one truck 2 is used to carry in and out will be described.

As shown in FIG. 1, the cart 2 carrying the roll paper travels to a position directly below the traverser 3 waiting at the storage shelf row 18 (see FIG. 3) where the paper is to be stored, and then stops. Next, the crane 4 that has moved into the traverser 3 lifts up the roll paper 5 on the cart 2. At this time, the support beam 9 of the temporary storage area 8
(see Figure 5) is in an open position.

Next, the support beam 9 is closed and the roll paper 5 is placed on the temporary storage area 8. During this time, the cart 2 moves to the next row of storage shelves 18 and waits. On the other hand, the crane 4 moves to the next storage shelf row 18 by the traverser 3, travels to a predetermined location in the storage shelf row 18, pulls up the desired roll paper, returns to the traverser 3, The roll paper is mounted on the cart 2. During this period, the movement of the crane 4 is as follows: placing the roll paper 5 on the temporary storage area 8 → transferring it to the adjacent storage shelf row 18 together with the traverser 3 → reciprocating movement to carry out the desired roll paper from the storage shelf row → moving to the trolley 2 is installed, and its movement is minimal. That is, the crane 4 actually travels only once over the storage shelf row 18.

Next, the traverser 3 is moved to just above the temporary storage area 8, and the roll paper 5 on the temporary storage area 8 is lifted up by the crane 4 and stored in a predetermined storage shelf. Next, a description will be given of carrying-out and carrying-in when a plurality of carts 2 are used. First, to explain about carrying in, all carts 2 are loaded with roll paper at the time of carrying in.
In this case, the crane 4 is stopped within the traverser 3, and only by moving the traverser 3, the roll paper 5 is placed on the temporary storage area 8, and the cart 2 is quickly made empty. In this embodiment, since there are four temporary storage areas 8, four carts 2 are processed. In this way, the four trolleys 2 are emptied, and while each trolley 2 is traveling to do the next job, the temporary storage area 8
Store the roll paper in the storage shelf.

Next, to explain about carrying out, in the case of carrying out, an empty cart 2 for carrying out comes. In this case, before the trolley 2 arrives, the desired roll paper is transported to the temporary storage area 8, and when the trolley 2 travels directly below the temporary storage area, the crane 4 transports the paper from the temporary storage area 8 onto the trolley 2. It is only necessary to install it on the Further, when loading and unloading are carried out simultaneously, correspondence between the trolley 2 and the crane 4 is selectively performed by combining the above-mentioned basic operations of loading and unloading depending on the situation at the time.

〔Effect of the invention〕

As detailed above, according to the three-dimensional warehouse for storing roll paper of the present invention, the crane running rails are provided along the rows of storage shelves, the traverser running rails are provided directly above the loading and unloading path, and the rolling paper is We have set up a temporary storage area directly above the loading and unloading path at a height that allows the vehicle to pass through while loaded, ensuring reliable correspondence between the trolley and crane for loading and unloading, and reducing idle time for the trolley and crane. was able to be drastically reduced.

As a result, it is possible to create a multi-story warehouse with excellent loading and unloading properties, which has great practical effects.
