Description

DETAILED DESCRIPTION OF THE INVENTION <Technical Field> The present invention relates to a method for stacking printing rolls suitable for storage and transportation in printing factories, plate making factories, and automated warehouse systems for printing rolls.

<Prior Art> Conventionally, no pallet or rack device exclusively for printing rolls has been provided. This is because printing rolls have various diameters, and if the printing roll is placed horizontally on the floor, the roll surface will be scratched. Therefore, printing rolls are placed upright on the side of aisles in printing factories and plate-making factories, in storage rooms, or warehouses, making it impossible to utilize space efficiently. Furthermore, if the printing roll falls over, the printing roll may be damaged or deformed, which is dangerous.

<Object of the invention> The present invention was devised in view of the above points, and
To provide a method for stacking printing rolls that is easy to handle and allows printing rolls to be stacked in a state where they are sandwiched in each stage, and even rolls having different diameters can be stacked together.

<Structure of the Invention> The method for stacking printing rolls of the present invention includes stacking a pair of arm-shaped first-stage pallets with an upward slope toward the overhanging end on a pair of guide posts set upright on a base at a required interval. , and place two or more printing rolls horizontally on the pallet, and then a pair of arm-shaped second stage pallets that slope toward the overhanging end are engaged with the pair of guide posts and lowered. Then, a spacer is sandwiched between the guide post engaging part and the guide post engaging part of the first stage pallet, and the second stage pallet is floated above the roll placed on the first stage pallet to print on the second stage pallet. It is characterized in that two or more rolls are placed horizontally, and in this way, a plurality of printing rolls are placed on each tier of pallets.

In order to prevent the printing rolls from being scratched due to the above stacking, it is necessary to interpose a protective material between the printing rolls so that the printing rolls on the same stage do not come into direct contact with each other, and also to It is necessary to interpose a protective material such as rubber, flexible plastic, or leather between the printing roll and the pallet. In this case, a roll rack shelf using the printing roll stacking method of the present invention is constructed by covering the guide posts and pallets with the protective material, and the protective material is sandwiched between the printing rolls on the same tier. good. Preferably, a band-shaped protective material is wrapped around the printing rolls to prevent printing rolls on the same stage from coming into close contact with each other, and if the printing rolls are prevented from coming into direct contact with the guide posts and pallets, the protective material can be wrapped around the guide posts and pallets. It is good because there is no need to cover it.

<Example> FIGS. 1 and 2 are a side view and a front view of a roll rack shelf for explaining an example of the printing roll stacking method of the present invention.

This roll rack shelf consists of a cart 1, a base 2,
Guide posts 31, 32 and pallets 41a, 4
1b, 42a, 42b, 43a, 43b,...
Spacers 51a, 51b, 52a, 52b, 5
It consists of 3a, 53b, and so on. The base 2 is positioned and placed on the trolley 1 by a forklift. The guide posts 31 and 32 are the base 2
For example, lightweight C-shaped channel material is used. Palette 4
1a, 41b, 42a, 42b, 43a, 43
b,... have guide posts 31, 32 at their base ends.
It has a guide post engaging portion that fits into the channel groove from the upper end and is movable up and down. This guide post engaging portion may be a plate that can slide loosely within the groove of the channel material. And each pallet 41a, 41b, 42a, 42b, 43a,
43b, . . . are formed with an upward slope toward the overhanging end. Spacers 51a, 51b, 52
a, 52b, 53a, 53b, ... can be raised and lowered by fitting into the channel grooves from the upper ends of the guide posts 31, 32, and the guide post engagement portions of the lower pallet and the guide posts of the upper pallet It is located between the engaging parts. The required length of each spacer is selected according to the maximum diameter of the roll placed on the lower pallet so that the upper pallet can be floated above the roll placed on the lower pallet.

Next, a method of stacking printing rolls according to the present invention will be explained by explaining how to use the roll rack shelf having the above structure.

The first stage pallets 41a and 41b are fitted into the channel grooves at the upper ends of the pair of guide posts 31 and 32 provided upright on the base 2, and are lowered until the guide post engaging portions abut against the base 2. Then, printing rolls R11, R12, and R13 covered with band-shaped protective materials are placed on the pallets 41a and 41b horizontally. Next, printing rolls R11, R12, R1
Spacers 51a, 51b of the required length selected according to the maximum diameter of 3 are fitted into the channel grooves at the upper ends of the guide posts 31, 32, and placed above the guide post engaging portions of the first stage pallets 41a, 41b. to be located. Then, the second stage pallets 42a, 42b
The guide post engaging portion of the guide post 31, 32
Spacer 5 fitted into the channel groove at the upper end of
1a and 51b. Then, the second stage pallets 42a and 42b become the first stage pallet 41.
Printing rolls R11, R12 placed on a, 41b,
It will be in a state that is higher than R13. Then, the printing rolls R21, R22, R23 covered with band-shaped protective materials are placed horizontally on the pallets 42a, 42b. In this way, the upper pallets are stacked one on top of the other in order to prevent them from riding on the lower printing rolls. When moving the roll rack shelf, a roll fall prevention device (not shown) is attached to the tip of the pallet in each stage, and the base 2 is lifted by a forklift and placed on the trolley 1. Note that a roll rack shelf may be constructed by extending arm-shaped pallets on both sides of the guide post, and a plurality of printing rolls may be placed on each stage on both sides of the guide post.

Note that the printing roll can be removed from each stage.

<Effects of the Invention> As explained above, the printing roll stacking method of the present invention has the following effects.

(1) The printing roll is placed on an arm-shaped pallet with an upward slope toward the overhanging end, and if a device to prevent the roll from falling off is attached to the tip of the pallet, the printing roll will not fall during transportation. do not have.

(2) The procedure is simple because it is only necessary to engage or remove the arm-shaped pallet with the guide post.

(3) Since the arm-shaped pallet moves up and down, printing rolls with different diameters can be loaded together.
Can be stored efficiently.

(4) Since the upper pallet does not ride on the lower printing roll, there is no stress on the printing roll, and the printing roll can be removed from each tier.

In addition to the above, if a band-shaped protective material is wrapped around the printing rolls to prevent printing rolls on the same stage from coming into close contact with each other, and also to prevent the printing rolls from coming into direct contact with the guide posts and pallets, , there is no need to cover the pallets and guide posts of the roll rack shelf with protective material.
It is inexpensive and easy to work with.
