Abstract

PURPOSE:To cut sheets which are difficult to treat, such as a sheet for wall material where the kneading surface layer of stone particulates is applied to the surface of a base cloth without getting out of shape or generating wrinkles, and load a pallet with them in order. CONSTITUTION:A pair of cutter knives are pushed up from the bottom of the central part of a sheet fed in a continuous condition to form a hole, and are moved in an opposite direction to each other, thus cutting the sheet. The cut sheet is placed on a traveling frame 3 provided with a traveling conveyer 14 and moved onto a pallet 15. While the traveling frame 3 is being retreated, a transferring conveyer 14 is advanced at an even speed to the traveling frame, thus placing the sheet onto the pallet 15.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cutting / transferring sheets used for cutting a wall material sheet for interior / exterior of a building into a certain size and stacking it on a pallet, and a sheet cutting therefor. The present invention relates to an apparatus and a sheet transfer apparatus.

[0002]

2. Description of the Related Art A wall material sheet obtained by applying a kneading surface layer containing stone particles as a main composition on the surface of a base cloth such as a non-woven fabric is manufactured in a continuous state, and the kneading surface layer applied by a coating machine is semi-dried. In this state, it is cut into a certain size by a cutting machine. However, since the base cloth has viscoelasticity, the kneading surface layer is a brittle, stoney layer, and thus there are problems that wrinkles are formed on the sheet during cutting and the kneading surface layer is likely to lose its shape.

Further, the cut sheets must be stacked on a pallet. However, since the kneading surface layer is semi-dry and the whole is in a soft state, wrinkles may occur during transfer to the pallet, and kneading may occur. There is a problem that the surface layer is likely to lose its shape.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the prior art, and accurately cuts a sheet having a kneading surface layer, such as a wall material sheet, into a pallet without causing wrinkles or deformation. The present invention has been made to provide a method of cutting and transferring a sheet that can be transferred, and an apparatus used for the method.

[0005]

The sheet cutting / transferring method of the present invention, which has been made to solve the above-mentioned problems, includes a pair of cutter knives from below the central portion of the sheets which are continuously fed. Sheet is cut by pushing up and moving in opposite directions, the cut sheet is placed on a moving frame equipped with a transfer conveyor and moved to the pallet, and the moving frame is retracted and the transfer conveyor is advanced. The sheet is placed on the pallet by the above.

Further, the sheet cutting apparatus of the present invention comprises a pair of left and right moving mechanisms for moving the cutter knife from the central portion to both end portions of the sheet on the lower surface of the sheet fed continuously, and the raising and lowering of the cutter knife. And a mechanism is provided. Further, according to the sheet transfer device of the present invention, a moving frame that travels between a receiving position of cut sheets and a stacking position on a pallet is moved at substantially the same speed as the retreating speed of the moving frame when the stacking onto the pallet. It is characterized in that a transfer conveyor for sending out the sheet is provided.

[0007]

According to the present invention, a pair of cutter knives are quickly pushed up from below the central portion of a continuous sheet to open a hole, and the sheets are moved in opposite directions to cut the sheet from the central portion to both ends. As a result, the sheet can be cut without losing its shape. The cut sheets are placed on a moving frame equipped with a transfer conveyor and moved to the pallet.The transfer conveyor is advanced to feed the sheet, and the moving frame is retracted at approximately the same speed to move the sheet onto the pallet. Since the sheets are loaded, the sheets can be loaded in an orderly manner on the pallet without wrinkling or deformation of the sheets.

The present invention will be described below in more detail with reference to the illustrated embodiments. FIG. 1 is a plan view showing an embodiment of the present invention, and FIG. 2 is a front view. In these figures, 1 is a continuous sheet transfer conveyor, 2 is an intermediate conveyor, 3 is a moving frame, and 4 is a pallet support. The transfer conveyor 1 transfers a sheet for wall material in which a surface of a base cloth is coated with a kneading surface layer of stone particles in a continuous state at a constant speed. A sheet cutting device 5 is provided on the lower surface of the sheet between the transfer conveyor 1 and the intermediate conveyor 2.

The sheet cutting device 5 has a moving mechanism 9 in which a cutter knife 8 is attached upward to a cutter moving chain 7 stretched between sprockets 6 as shown in FIG. 4, and this moving mechanism. 9 together with a lifting mechanism 10 for moving the cutter knife 8 up and down. Figure 1
As shown in FIG. 3, the sheet cutting devices 5 are provided in pairs on both sides of the center line of the sheet, and each cuts from the central portion to the end portion of the sheet. In addition, the whole is arranged with an angle with respect to the traveling direction of the seat,
This is in consideration of the traveling speed of the sheet.

The sheet cutting device 5 is constructed so that the cutter knife 8 is first positioned in the central portion of the sheet and the lifting mechanism is used.
The cutter knife 8 is pushed up toward the sheet by 10 to make a hole in the sheet. Subsequently, the moving mechanism 9 moves the cutter knife 8 from the central portion to the end portion of the sheet,
Cut the sheet. The position of the cutter knife 8 of each cutting device 5 is slightly offset, but the sheet is sure to be moved because the cutting knife of one cutter knife 8 moves while the other cutter knife crosses it. To be disconnected. If the kneading surface layer is semi-dried by performing the cutting in such a manner, it is possible to cut the sheet without causing mold deformation and wrinkling.

The cut sheet is then transferred to the intermediate conveyor 2
Is transferred to the moving frame 3. However, since the intermediate conveyor 2 can be raised and lowered by the cylinder 11 as shown in FIG. 2, when the cut sheet is defective, the intermediate conveyor 2 can be lowered and the sheet can be removed from the line.

The moving frame 3 is attached to the chain 13 provided on the upper beam 12, and the receiving position of the cut sheets shown in FIG. 2 and the stacking position on the pallet shown in FIG. 3 (above the pallet support base 4). Position) is capable of traveling between. A transfer conveyor 14 is provided on the moving frame 3.

The moving frame 3 first receives the cut sheet from the intermediate conveyor 2 at the sheet receiving position. At this time, the moving frame 3 is stopped, and the transfer conveyor 14 moves at the same speed as the intermediate conveyor 2 to receive the sheet. Next, the moving frame 3 travels to a position above the pallet support base 4 with the transfer conveyor 14 stopped. Next, by moving the transfer frame 14 backward while moving the moving frame 3 backward, the sheet can be placed on the pallet 15 as shown in FIG.

The pallet 15 on which the sheets are placed in this way
Are transported to the adjacent station by the first pallet moving device 16. In addition, 17 is a pallet stock station, and an empty pallet is set by the second pallet moving device 18.
15 is supplied from the pallet stock station 17.

[0015]

As described above, according to the sheet cutting / transferring method and apparatus of the present invention, it is possible to obtain a sheet for wall material in which the surface of the base cloth is coated with the kneading surface layer of stone particles. Even if the sheet is difficult to handle, there is an advantage that it can be cut without being deformed or wrinkled and can be neatly stacked on the pallet.
