Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a switching supply device for sheets formed on a plurality of rolls [7. Crunch of a sheet forming machine. The sheet with roll 8 to be fed into the starting end of the first sheet is passed across the moving direction of the first sheet and the first sheet whose λ is +iiij).
・The second support is additionally supported by a movable platform that goes in and out of the bottom surface.
So that it can be supplied by switching between the sheet and the sheet (for two reasons,
For example, when there is a shortage of sheets (for example, a sheet with a length of 6), the sheets can be switched and fed, and the sheets can be wound into multiple rolls to have a total length of i1, or printed.
) i can be changed to a different sheet supply.

(Prior Art) It is well known that a sheet forming machine unwinds and feeds a roll-wound sheet from a shaft mounted on the machine to the starting end of crumbbutene, but depending on the shape of one roll-wound sheet, the forming operation may be difficult. The disadvantage is that the time is short, and therefore it is not easy to stop the forming operation and transfer the heavy roll-wound sheet to the shaft frame in a short time. For this reason, a molding machine has been developed that has a concept of installing multiple shafts in a molding machine and mounting one rolled sheet on each shaft, but as the number of shafts increases, Since the installation of the molding machine itself also increases the length, there is a need for an improvement that allows multiple rolled sheets to be sent one after another to the starting end of the crumb chain while suppressing the length6. The present invention addresses the shortcomings and needs of the prior art equipment mentioned in the previous section, and provides a sheet forming machine that can be installed to feed multiple rolled sheets to the starting end of crumbbutien with little increase in length. The purpose is to provide equipment.

(Means for Solving the Problems) The present invention has been made to meet the objects stated in the previous section, and is arranged in such a way that, in front of the starting end of crumbbutene for sheet forming, there is a first sheet guide and a second sheet guide, each of which is oriented toward the starting end. A first shaft mount is provided, in which the sheet guides are arranged vertically, and a roll-shaped winding part (hereinafter simply referred to as the winding part) that feeds out the first sheet to be rewound is mounted. The first sheet to be rewound is sent to the starting end of the crumb chain via the first sheet guide, and the first sheet is moved in and out of the lower surface of the sheet across the moving direction of the sheet between the first shaft mount and the first and second sheet guides. A table is provided, a second shaft frame is installed on the movable table, and the second sheet is unwound from the second shaft frame, and the second sheet is passed through the second sheet guide to the starting end of the crumb chain. Regarding the switching supply device for multiple roll-wound sheets, the special feature is that the second sheet is fed into the moving table, and the second sheet is not rolled in while the first sheet is being fed. When the first sheet is depleted, the movable table supporting the second sheet by the second shaft mount is moved to the bottom surface of the sheet, and when the first sheet is depleted, the second sheet is started to be supplied, and while the second sheet is being supplied, a new sheet is placed on the first shaft mount. When the second sheet runs out, the moving table moves from the bottom surface of the sheet to the side and supplies a new sheet to the second glazing frame. By repeating the operation of pivoting the winding part of the two sheets, it is possible not only to avoid interruptions in the molding operation due to lack of supplied sheets, but also to ensure that the first sheet and the m2 sheet, which have different printing patterns, are prepared in a timely manner. (You can also rub it.)

In the above-mentioned embodiment, when the first sheet C+ is depleted, the second sheet C2 is automatically sent to the starting point I of Clambutien 2, and when the second sheet C2 is depleted, the first sheet C2 is automatically sent to the starting point I of the Clambutien 2. However, the Sheet F C1% C2 does not necessarily continue to be supplied automatically, but it is possible to exchange and feed the first and second sheets with different printing widths. Therefore, the automatic feeding function described above is not necessarily necessary, and the point is that the provision of the moving table 32 makes it possible to feed the first sheet C1 and the second sheet C2.

The automatic operation of this embodiment will be explained.

This description will be made assuming that when the first sea) C+ is being supplied, the automatic feeding with the second sea) C2 is switched. The same applies when automatic switching is performed between feeding the first sheet C1 from the second sheet C2.

When the first sheet C1 is being fed into the crumb chain 2, the photoelectric switch 22 causes the continuous rotation of the rear unwinding roll 9 and the crank chain 2 of the front unwinding roll 18.
A high-speed intermittent drive corresponding to the speed of the intermittent drive is commanded, and the presser roll 10 and the presser roll 19 are moved to each roll 9.1 in Aij by the operation of the cylinder 11.21.
8, the sheet guide plate 2 is moved from the position shown by the chain line to the position shown by the solid line by the cylinder 13, and allows the dancing roll above the position shown by the chain line to move to the position shown by the solid line. Therefore, while the unwinding rolls 18 at the crumbutien 2 and ifj positions are stopped intermittently, the first unwinding roll 9 is
The first sheet C1 that is rewound from the shaft frame 8 becomes slack due to the stoppage of the front rewind roll 13, and at this time, the upper dancing roll 16 is gradually brought to the position of the solid line by the cylinder 17. Climb up and take up the slack.

When the crank chain 2 starts running at high speed, the front rewind roll 18 is also driven at the same time, and at this time, the cylinder 1
7, the upper dancing roll 16 is rapidly lowered, and during this time, the unwinding roll 9 at the rear is also added to the unwinding length, and the required length of the first belt C+ is started in a tensioned state via the first sheet guide 5. Send to M Department I.

In this way, the intermittent feeding of the first sheet c1 is repeated on the feeding path <i).

In the meantime, the movable table 32 with the winding part of the second sea) C2 mounted on the f52 shaft frame 33 is moved to the position shown in FIG.
Move to the bottom of i). At this time, the lower Gunsing roll 46 is resting at the position indicated by the chain line due to the extension of the shilling 48 and the movement of the arm 47 in the h direction, so the shilling 1.
