Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to pulling out a web wound into a roll, conveying the cut sheets by a conveyor, and continuously depositing them by a single lay boy.

The conventional single layboy deposition method is
This was carried out intermittently by stopping the entire cutter when a certain amount of sheets were deposited, and replacing the fully loaded layboy with an empty layboy to redeposit the sheets.

Therefore, an object of the present invention is to further improve the above-mentioned method and, in view of the above, to improve the sheet accumulation by suddenly and temporarily protruding the leaf spring and air table to receive the sheets when changing from a fully loaded layboy to an empty layboy. After changing the fully loaded Layboy to an empty Layboy during light loading, the leaf spring and air table are returned to their original positions and then pulled back to provide continuous deposition.

In the following, a preferred embodiment of the present invention is shown in a side view in FIG. 1 and a front view in FIG. 2.
For sheets such as paper and plastic, the web is cut by a cutter not shown in the figure, the cut sheet is conveyed, and when the sheet 7 is ejected from the final conveyor 1 via the ejection roll 2, it is stopped at the stopper. The sheet hits the front jogger 8, which plays the role of a holder, and backs up, and the returned sheet 7 hits the back jogger 4, forcing the sheet 7 into the correct position and neatly stacking it on the layboy 3.

So when the amount of Layboy 3 is full,
The fully loaded sheet count-up signal is activated, and the stacking of the Layboy 3 is temporarily interrupted, during which the sheet 7 is temporarily received by the combination of the leaf spring 5 and the air table 6. To explain in more detail, the leaf spring winding 5B of the leaf spring 5 and the air table 6 are installed on the right side (FIG. 1) of the ejector roll 2 and the baggage roller 4, that is, on the lower side of the conveyor 1 for sheet conveyance. In response to the sheet count up signal instruction, the tongue tip 5A of the leaf spring 5 moves into the groove of the lower protruding roll 2A and the window 4 of the back jar 4.
A, the air table 6 is ejected and inserted onto the stacked sheet of the Layboy and the lower surface of the protruding sheet 7, and then the air table 6 is advanced by the transmission member 9.

Therefore, from the above, the sheet 7 after the count-up creates a time lag in the deposition of the temporary Layboy on the tongue tip 5A of the leaf spring 5, hinders the falling speed, delays the sheet falling, and installs the above air table 6 in that space. Let it enter. In addition, a large number of small holes 6A are provided on the upper surface of the air table 6 to blow out air to reduce temporary accumulation with the sheet 7 and to float the sheet 7, thereby facilitating the transfer process in the next process.

By the way, the fully loaded Layboy 3 processes the already deposited sheets using a lifter or the like within the above-mentioned time, replaces it with an empty Layboy, ascends to the sheet stacking position, and prepares for stacking. This method allows for easy transshipment of the accumulated amount of sheets.

As is clear from the foregoing description, these effects include the use of leaf springs and By inserting an air table with a large number of ejection holes, it is possible to easily change from a fully loaded Layboy to an empty Layboy without stopping the cutter, and to reduce the levitation of the sheet during sudden temporary sheet levitation and deposition. Therefore, it is possible to carry out slight continuous loading without damaging the sheet.

[Brief explanation of the drawing]

FIG. 1 is a side view of the continuous sheet stacking method of the present invention, and FIG. 2 is a front view of the stacking layboy. In the figure, 1 is the final conveyor, 2 is the protrusion roll, 2A is the groove of the lower protrusion roll, 3 is Layboy, 4 is the back gear, 4A is the window, 5 is the leaf spring, 5A is the tongue tip, 5B is the leaf spring winding, and 6 is the leaf spring winding. 6A is an air table, 7 is a seat, 8 is a front jogger, and 9 is an air table transmission member.

Claims (1)

[Claims] 1. When stacking sheets continuously without stopping the cutter, it is necessary to replace the layboy when the sheets accumulate to a certain level. On the bottom,
A combination of a leaf spring and an air table that blows air from small holes is projected, and the continuously conveyed sheet is temporarily placed on the leaf spring and air table, while the sheet after replacement is A method for lightly stacking continuous sheets, characterized in that when an empty layboy returns to a stacking position, a leaf spring and an air table are pulled back to perform temporary continuous stacking of sheets.
