Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an apparatus for cutting long sheets, for example, wrapped synthetic resin sheets, fabrics, paper, etc. It relates to a cutting device that is rotatably held and cuts a sheet of any synthetic resin to any length. Conventionally, the above-mentioned synthetic resin sheet is cut using scissors, but in this case, the cutting edge is However, there are disadvantages in that the edges are not straight, and it is difficult to make the edges perpendicular to the longitudinal direction of the synthetic resin notebook.

Two types of cutting devices fixed to a notebook holding stand are known to solve the above-mentioned drawbacks. In the first cutting device, the thin grooved cutter receiving member is fixed to the sheet holding base with the fine grooved surface being vertical, while the power cutter is attached to the sheet holding base via the cutter rail through an arm. Supporting and composed of
Ru. This device is fixed to the sheet holding table at a height that facilitates the cutting operation, and moving the sheet held at the top or bottom of the sheet holding table to the cutting device requires a tedious work. Further, after cutting, there is the complication of having to re-wrap the sheet in the relatively long distance u1f between the cutting device and the notebook wrapping section. Furthermore, since the cutting surface is vertical, the pressing pressure of the cutter rail against the grooved surface is small, and it is necessary to press the cutter rail by hand during cutting.

In the conventional second cutting device, the slotted cutter receiving part is fixed to the sheet holding base with the slotted surface facing upward and horizontally, while the cutter rail I? The i7 ends extend vertically at both ends of the aa cutter receiving member) and fit into the inverted J-shaped grooves of the metal plate. The upper bent portion of the inverted J-shaped groove is bent toward the opposite side of the sheet holding sleeve, and this state is maintained by lifting the cutter rail upward to move it past the inverted J-shaped bent portion.

This device is also fixed to the sorting holding table at a height that makes it easy to perform cutting operations, so it cannot be held at the top or bottom of the sorting holding table.
It requires a cumbersome operation to move the sheet to the main cutting device, and after cutting, it is difficult to move the sheet over a relatively long distance between the cutting device and the 7-piece winding section.・Square winding 4=J on the winding part
There are complications that must be overcome. ! Additionally, the raised cutter rail has the disadvantage that it obstructs the operator's view.

The present invention has been made in view of the above-mentioned problems of the conventional cutting device. The object of the present invention is to provide a cutting device that can be moved to any convenient position for cutting the sheet holding table.

Another object of the present invention is to provide a cutting device with high working efficiency in which the constituent members of the cutting device do not obstruct the view of the cutting operator.

Still another object of the present invention is to eliminate static electricity generated when a rolled synthetic resin sort is unrolled, thereby preventing dust from adhering to the synthetic resin sheet and causing electric shock to workers. It is an object of the present invention to provide a cutting device that prevents the generation of gases that cause explosions and ignition of flammable gases.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in Fig. 1 and Fig. 2, the synthetic fat/fat 1 has the following properties:
It is wrapped around a paper cylinder 2 and held by a sheet holding table 4. The sheet holding stand 4 is composed of a plurality of round rods 8 horizontally and removably attached to a main body frame 6, and holds the resin sheet 1 by moving the round rods 8 inside the paper cylinder 2. Hold it on stand 4.

As shown in FIGS. 1 to 3, the cutting device IO includes a pair of hook members 12, a pair of first fitting parts 14 fixed to the hook members 12, and a round bar 8 attached to the first fitting member J4. The seat receiving part 16 and the first fitting part 1'1 are attached so as to be parallel to each other.
A pair of second fitting members 18 that are slidably fitted to the second
It consists of a cutter rail 20 that is extended on the upper end of the fitting member so as to be parallel to the round bar 8, a cutter 22 that slides on the cutter rail 20, and a static electricity removal brush 24. The hook portion 4: A12 includes a hook portion 28 that is hooked onto the round bar bone protrusion 26 of the main body frame 6, a tilting portion 30 that is used to extend the first low joint shrine 14, and an abutment that abuts the main body frame 6. Contact part 32
The inclined portion 3
0 maintains its upper part inclined in a direction away from 4 holding the sheet.

A first fitting portion hoist 14 and a static electricity removal brush 24 facing the user are screwed to the inclined portion 30 of the hook member 12 . The sheet receiving member 16, which has a surface having a narrow groove 34 for a cutter receiver on the upper surface, is attached to the first fitting member 14 with the surface having the narrow groove 34 inclined toward the opposite side from the sheet holding base 4. . The second fitting member 18 fixes a J-shaped groove 36 in its longitudinal direction, and a pin 38 provided on the first fitting member 14 is engaged with the J-shaped groove 36. The cutter rail 20 attached to the upper end of the second fitting part 18 has a U-shaped cross section, and a cutter penetration groove 40 in the longitudinal direction is provided in the center of its central surface. It is configured to be able to sandwich the outer surface of the receiving portion side 16. The inner surface of the cutter rail 20 has S, J? The notes are glued together. The cutter 22 is configured to sandwich the outer surface of the canter rail 20 and slide on the cutter rail 20. A semicircular blade 42 is installed inside the cutter 22 and passes through the cutter penetration groove 40 of the cuckoo rail 200 and the narrow groove 34 of the sheet receiving member 16. The blade 42 may be a square shaped blade or a rotatable circular blade.

With the above configuration, the cutting device 10 is hooked onto the round bar receiving protrusion 26 holding a desired notebook. next,
The cutter rail 20 is lifted upward and toward the sheet holding table 4, the pin 38 engages with the bent tip of the J-shaped groove 36, and at the same time the lower end of the second sliding member No. Part 1
1nj of 6 and stabilizes in the state shown by the phase 1 quadrant in FIG. In this state, the cutter rail 20 is close to the sheet holding table 4, so it hardly blocks the view of the cutting operator. Next, the cutting operator inserts his/her hand between the cutter rail 20 and the note receiver It 1 6 and pulls out the sort 1. At this time, a static electricity removing blank 24 disposed near the lower pole of the traveling path of the sheet 1 discharges static electricity generated in the rolled sheet and the sheet unwound and pulled out. The static electricity removing cyrano 24 releases the charged static electricity to the sheet holding table 4 which is electrically connected thereto.

After pulling out the notebook to the fixed position, remove the cutter rail 2.
0 is lowered, the sheet 1 is inserted and fixed between the sheet receiving member 16 and the cutter rail 20, and the cutter 22 is moved to cut it.
