Description

  The present invention mainly relates to a roll sheet cutting apparatus that can store a roll sheet in one place without taking up a space, easily pull out the sheet material by hand, and can easily cut the sheet straight with a desired length. It is.

  When cutting the roll sheet, if there is no cutting device, the sheet is pulled out with the roll sheet upright, and cut using a cutter knife, scissors or the like while pulling the end of the sheet. However, this approach creates several problems. First of all, it does not cut straight. After cutting, the sheet hangs down. When the remaining seat is low, it cannot be placed upright. When cutting with a knife while holding the sheet with one hand, the sheet may be cut to a point where cutting is not necessary.

Moreover, a round blade is used for the generally known slide cutters for roll sheets. Usually, since thin sheet cutting is assumed, the diameter of the round blade is relatively small, and it is generally difficult to cut a thick sheet in the round blade type as compared with the cutter knife.

The above-mentioned slide cutters for roll sheets are mainly intended to cut the sheet in a straight line, so the length to be drawn when the roll sheet is pulled and cut depends on a method such as using a long ruler as a guide. When there is no other standard, the desired length is cut by prediction, and when the desired length cannot be cut, waste such as recutting the sheet has occurred.

A cutter structure that allows roll sheets to be stored in place, prevents the sheets from dripping, and can be used with a commercially available cutter knife instead of a round blade. Safe and easy cutting of thick sheets. Another object of the present invention is to devise a roll sheet cutting device that can perform the cutting operation and can know the drawing length of the sheet when cutting.

  The present invention hooks and stores the roll shaft inserted into the roll sheet with a hook portion provided at the column portion of the frame.

  In order to cut the roll sheet safely and easily, the sheet can be cut straight without applying excessive force by fixing the cutting table with slide cutter function to the column part of the frame.

On the front side of the cutting table, a sheet plate with a slide cutter attached thereto is coupled with a step hinge. When a sheet is sandwiched between a sheet pressing plate that is opened and closed and a table, pulled out, and cut, it can be easily cut while pressing from above.

In order to cut safely, a safety lock is attached to the slide cutter body to prevent danger when using the knife of the cutter knife, and the cutter does not protrude unless the lock is released.

In order to safely cut, a cutter guard portion that covers the protrusion of the cutter is provided at the front lower portion of the cutting table for preventing the danger of the cutter that is a concern at the time of cutting.

A tape measure stand is attached to the sheet leather plate, and a commercially available hook fitting is attached. Simply insert a tape measure with a stopper into the stand, and then use the tape measure as a guide for how long the sheet is pulled out and cut. You can use it to cut the length.

  As described above, the roll sheet cutting device of the present invention is not a round blade but a slide cutter structure with a safety lock using a commercially available cutter knife, so that the sheet material can be cut regardless of the cutting thickness of the sheet material that can be cut. The number of materials that can be cut is increased, and the tape measure stand is provided, so that it is useful as a simple and safe roll sheet cutting device with less waste of the sheet material while determining the standard length of the sheet to be cut. Is.

  Each of the upper and lower roll sheets is drawn out in a state of being wound from the gap between the two roll hang shafts. At this time, the sheet from the upper stage is sandwiched between the two roll hang shafts, and the sheet is difficult to return.

Further, the roll sheet from the lower stage is less likely to return when the sheet is pressed by a sheet spring with a spring hinge provided on the cutting table.

The roll sheet pulled out from the upper stage is further pulled forward, and the leading end is slid into the gap between the cutting table and the sheet press cutter plate. Further, open the plate that can be opened and closed with a step hinge, and pull the sheet from inside. When you release your hand from the plate, grab both ends of the sheet and pull out the sheet, the plate will hold the sheet under its own weight. At the same time, since the plate angle in contact with the sheet has an effect of preventing the sheet from being reversed, the sheet can be cut in a state where it can be easily cut.

In the above-mentioned state, when cutting the sheet, pull it out to any length, and when cutting the length by deciding on the length guide, the tape measure stand provided at the front left corner of the sheet spring cutter plate is equipped with hook fittings and stoppers Insert and set the tape measure, pull the tape measure to the length you want to cut, lock it, and cut it while pulling the sheet up to that length as a guide, so you can cut without waste such as incorrect cutting length.

The slide cutter with safety lock starts cutting at the position near the left edge of the front, pulls out the aforementioned sheet, releases the safety lock while holding the sheet with the plate, presses the button, and causes the cutter blade to protrude in the cutter guard. While sliding the slide cutter from left to right, the roll sheet is easily and safely cut.

After cutting the sheet, the slide cutter is returned to the cutting start position, the sheet pressing cutter plate is lifted, both ends of the roll sheet are picked up with both hands, drawn to an arbitrary length, and cut according to the procedure described above.

    The set switching operation from the upper sheet to the lower sheet is performed on the cutting table. After the cutting is finished, when the sheet pressing cutter plate is lifted, the sheet is released from its own weight. The sheet is pulled back to the upstream side, the front side of the lower sheet held by the sheet press is pulled, and the sheet is cut in the same procedure as when cutting the upper sheet by pulling it further forward through the gap between the table and the plate. When the cutting is completed, the lower sheet is pressed and held by the weight of the plate and the sheet weight.

    In the above-described state, in the set switching operation from the lower sheet to the upper sheet, the plate is first lifted and the sheet is pulled back slightly upstream. You can grab a sheet that is placed on a lower sheet on the table and switch the set easily by the same procedure.

  An embodiment will be described below with reference to the accompanying drawings. As shown in FIG. 1, the pillar 1 is provided with at least one hook portion 3 for hooking the roll shaft 11 at least one at a vertical position with respect to the arm 2.

 Between the two pillars, two roll hang shafts 12 divided into an upper stage and a lower stage are provided at a position slightly higher than the table 4 and the mounting height. The upper roll hang shaft is slightly higher than the lower roll hang shaft on the front side, and a slight distance is provided between these two.

The left and right arms 2 are provided with a plate-like cutting table 4 on the front side at a position protruding from the front side. At the upper part on the front side of the cutting table 4, a seat plate 5 that is joined by a step hinge 6 is provided.
