Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a drawing machine for drawing the mounting position of a punching blade, etc. on the outer peripheral surface of a blade mounting wooden frame used in a rotary punching machine.

[Conventional technology]

A rotary punching machine, as disclosed in Utility Model Publication No. 59-20959, for example, includes a knife cylinder in which a punching blade of a predetermined shape is embedded in the outer peripheral surface of a cylindrical wooden frame for mounting a knife, and the knife cylinder. It consists of two anvil cylinders arranged in parallel, and is punched into a predetermined shape by passing cardboard or the like between the two cylinders.

Therefore, when embedding the punching blade in the wooden frame for attaching the cutter, a work is usually carried out to draw the mounting position of the punching blade on the outer circumferential surface of the wooden frame for attaching the knife. In such work, a drawing machine is carried out in which a wooden frame for attaching a cutter is supported by a wooden frame support drum rotatably supported by the machine frame, and a drawing is drawn on the outer peripheral surface of the wooden frame for attaching a cutter in this state. It is used.

[Problem that the invention attempts to solve]

However, since the above-mentioned drafting machine can only attach one type of cutter mounting wooden frame to one wooden frame support drum, the number of drafting machines corresponding to the size of the cutter mounting wooden frame can be attached. It is necessary to install a number of machines, which increases the equipment cost, and since each machine is about 3 meters long, there is a problem that if a number of machines are installed, there will be a shortage of installation space.

[Means for solving problems]

Therefore, in the present invention, a removable adjustment frame member 10 is mounted on the outer peripheral surface of a cylindrical wooden frame support drum 1 rotatably supported by a machine frame 5, and a cutter is attached to the adjustment frame member 10. This problem is solved by supporting the wooden frame 4.

[Effect]

By using one wooden frame support drum 1 as a base and replacing the adjusting frame member 10 with one whose outer diameter is approximately equal to the different inner diameters of the blade attachment wooden frame 4, all sizes can be made with one drafting machine. It can correspond to the blade mounting wooden frame 4.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. The wooden frame support drum 1 is a cylindrical body made of metal, and has rotating shafts 2 protruding from both ends thereof. Further, screw holes 3, 3, . . . are bored at equal pitches in the body portion 1a, and these holes are mainly for screwing in bolts 16 for supporting and fixing the knife mounting wooden frame 4. This wooden frame support drum 1 is rotatable with its rotating shaft 2 supported by the machine frame 5. The rotating shaft 2 protruding from one side of the wooden frame support drum 1 is connected to a rotation control drive unit 6 to freely control the rotation of the wooden frame support drum 1.

On the other hand, a rail 7 is installed diagonally above the rear side of the machine frame 5 in parallel with the rotating shaft 2 of the wooden frame support drum 1.
The rail 7 supports the pen device 8 in a slidable manner. The left and right movement of this pen device 8 and the pen 9
A computer (not shown) simultaneously controls the forward and backward movement of the blade and the rotation of the wooden frame support drum 1 to automatically draw a drawing on the outer peripheral surface of the wooden frame 4 for attaching the cutter.

Therefore, the adjustment frame member 10 is attached to the blade mounting wooden frame 4.
A pair of split bodies are overlapped at a predetermined interval in the longitudinal direction on the outer peripheral surface of the wooden frame support drum 1 in order to fix both ends of the wooden frame support drum 1, and as shown in FIG. This is a set. Its inner diameter is the same size as the outer diameter of the wooden frame support drum 1. The adjustment frame member 10 has an arcuate cross section with a convex shape, and has flange portions 11 on both sides,
A bolt 13 is inserted into a through hole 12 drilled in the frame support drum 11 and screwed into the screw hole 3 of the wooden frame support drum 1, thereby attaching the frame support drum 1 removably. Further, a screw hole 3a, which is the same as the screw hole 3 of the wooden frame support drum 1, is formed on the outer periphery of the convex portion of the adjustment frame member 10, which has an arc-shaped cross section.

Further, as shown in FIG. 3, the blade mounting wooden frame 4 is made of, for example, a pair of arcuate plates, which are formed into a cylindrical shape, and the left and right ends thereof are attached to the adjustment frame members 1.
0 on the outer circumferential surface of the convex portion, and then the bolt 1
6 is screwed into the screw holes 3a and 3 to support and fix it to the adjustment frame member 10.

In addition, a cutting machine 15 such as a router is slidably installed on the rail 14 installed on the front side of the wooden frame support drum 1, so that it can also be used as a cutting machine for the wooden frame 4 to which the blade is attached. It is something.

In the drawing machine of the present invention configured as described above,
The adjustment frame member 10 superimposed on the outer circumferential surface of the wooden frame support drum 1 is replaced in accordance with the inner diameter of the cutter attachment wooden frame 4, and the right and left sides of the cutter attachment wooden frame 4 are attached to the outer circumferential surface of the convex portion of the adjustment frame member 10. The side ends are overlapped and fixed by tightening the bolts 16.

In addition, although this example illustrated an automatic drafting machine,
Of course, it can also be used as a hand-drawn drafting machine.

[Effect of idea]

As explained above, according to the drawing machine of the present invention, the adjusting frame member 10 has an inner diameter that is approximately equal to the outer diameter of the wooden frame support drum, and an outer diameter that is approximately equal to the inner diameter of the wooden frame for attaching the cutter. Since the installation is replaceable, one wooden frame can be used to attach various sizes of cutlery4.
can correspond to As a result, equipment costs can be reduced, and work can be carried out in the same way as before with a minimum amount of space.

Moreover, if the existing screw holes 3 of the wooden frame support drum 1 are used to fix the adjustment frame member 10, the cost becomes extremely low since no changes are required to the conventional drafting machine.
