Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing boxes using sheet-like members such as cardboard and plastic sheets. As shown in the specification of No. 116655.

However, in this method, a female paper is adhesively fixed to a counter plate identified on a drawing plate via a base film. Therefore, when storing the female paper, it is necessary to protect it with two counter plates, which is disadvantageous in that it requires a large storage space.

In order to remove the above defect, when trying to store the female paper by peeling it off from the counter plate along with the base film, the adhesive was adhered to both sides, making it difficult to store, and another sheet-like member was placed on the adhesive side. In this case, a defect occurs in which the sheet-like member cannot be peeled off from the adhesive surface of the base film after one year or more has passed. In addition, when positioning the female paper at a predetermined position on the counter plate again, if there is glue on the female paper, this positioning work is not easy. Draw a pattern to check the female pattern W that has been created [If it crosses over, you will have to remove the counter plate from the drawing board, and this work may not be easy. In this case, the surface of the counter plate is uneven with adhesive and has defects that are not suitable for precision drawing.The purpose of the present invention is to provide a method of manufacturing a box that eliminates the above defects. The structure of the present invention will be described below with reference to the accompanying drawings.

In Figure PA1, it is a two-head XY numerically controlled machine, and is equipped with a known vacuum table 4. A large number of ventilation holes 6 are transparently provided in the vacuum table 4, and a vacuum chamber 8 (see FIG. 2) is formed at the bottom of the table 4. This is a Y rail that can be moved along the o12 X rail 14.16 that is connected to the intake device Ptvr.
An rY cursor 18 is movably mounted. Movement of the Y rail 12 along the X rail 14°16 and Y
Movement of the cursor 18 along the X rail 12 is configured to be automatically controlled by the machine.

20 The cutter head has a removable groove fixed to the Y cursor 18, and the structure inside the casing is stiff. r
l; Shown in Figure 2. In FIG. 2, 22 is a cutter, which is connected to a known lifting mechanism and direction control mechanism. 2411'' to a known lifting mechanism and direction control mechanism, and a disk-shaped suppressing member 26 is rotatably supported at the bottom of this holder plate. 28 is a holder plate that is attached to the case of the head 2o. A writing instrument 50 is supported by the marking instrument holder 28 so as to be able to move up and down, and the writing instrument 30 is connected to a known lifting mechanism 52.

The elevating mechanism and the direction control mechanism are controlled by six meters.

In the above configuration, the pattern information of the developed view of the box to be created and the tool control signal are inputted in advance into an input medium for a 1kItt calculator, such as a paper tape, using means such as two holes,
Prepare input media for box creation. Also, in the development diagram of the box to be manufactured, the folding line pattern information and tool control signals are summarized as 'J1. Enter the information into the input medium for the machine, and prepare the input medium for female mold creation.

Furthermore, on the upper surface of the underlay 34 such as a synthetic resin sheet, the lower surface of the female mold sheet 66 such as cardboard, which is the material for the female mold, is coated with a commercially available synthetic rubber adhesive that can be repeatedly pasted and stabbed using a spray set. Glue it with the glue, and then,
The lower surface of this underlay 64 is fixed to the table 4 by suction.

Next, input media for female mold creation are set in the input units of the n machines, and the X-Y head numerical control device is driven and controlled by the i machines. In accordance with instructions from the computer, the 20 hens are moved in a plane parallel to the four surfaces of the table along the pattern of folding lines in the box development diagram. On the other hand, cutter 22! "r While moving up and down with respect to the table 4, the rotation direction of the cutter 22 is controlled so that its side face always faces the direction of travel. As a result, the sheet 36V is aligned with the fold line of the box ρ development diagram to be produced. As shown in Fig. 6 in the corresponding part,
Parallel cuts 42 having a predetermined width are formed. Next, remove the upper part 34 from the bottom part of the sheet 36 surrounded by the cutting legs 43 and 42 by hand. This will result in C)3
6, a thick line-shaped cutout strip 44 is formed at a portion corresponding to the folding line of the developed view of the box to be manufactured. 0 The lower surface of a sheet-like member 46 of cardboard, plastic, etc. that will be the material of the box to be manufactured next. is adhered to the upper surface of the female mold sheet 36 using the spray from the above spray set.

Next, the input medium for box manufacturing is set in the input section of the computer, and the computer drives the Y-head numerical control device W to move the head 2o in a plane parallel to the 4th surface of the table. The sheet-like member 46 is controlled to move along the cutout strip 44 of the mold sheet 36 and the suppressing member 26 is controlled up and down.
A fold line 48 is formed that projects downward. Pressing member 26
However, when the suppressing member 26 descends directly above the notched line 44 of the female mold sheet 36 and with the side surface of the suppressing member 26 parallel to the longitudinal direction of the notched line 44, the suppressing member 26 plunges into the sheet-like member 46 to a predetermined depth. The surface of the sheet-like member 46 is recessed by the amount of this intrusion, and the back surface thereof protrudes into the cutout strip 44 of the female mold sheet 36, as shown in FIG. 4(a). In this state, the pressing member 26 moves along the notched line 44 of the female mold sheet 36. At this time, the rotation of the pressing member 26 is controlled so that its side surface is always parallel to the direction of movement. Due to the movement of the pressing member 26 along the cutout strip 44, the sheet-like member 46 has a fold line 4 whose thick width is not significantly different from the other parts, with the back side protruding by the amount f of the front surface.
8 is formed. Next, with the pressing member 26 held in the raised position, the head 20 moves along the outline 50 of the exploded view of the box. On the other hand, the cutter 22 is controlled up and down, and a portion of the sheet-like member 46tfi corresponding to the outline 50 of the developed view of the box is cut. The sheet-like member 46, which has been cut along the outline 50f of the developed view of the box and has a fold line 4B formed at a portion corresponding to the folded part of the box, is removed from the Baquième table 4 and the female mold sheet 36. After
It is bent and joined manually into a box shape.

In addition, when checking whether the input data of the input medium to the measurement l is correct, it is uneconomical in terms of time and cost to actually drive the cutter 20 and the suppressing member 26. Therefore, by using the above input medium and controlling the movement of the head 20 by a computer and drawing the pattern of the female cutting lines 40 and 42 and the pattern of the developed view of the box on the paper on the table 4 with the writing instrument 30, the above-mentioned It is possible to check whether the input data on the input medium is correct.

As described above, according to the present invention, the female sheet metal can be easily stored together with the underlayment, and since no adhesive is attached to the underside of the underlayment, when the female sheet is used again, the underlayment can be stored in a designated place on the table. It is possible to accurately and easily position the WK, and since the adhesive does not adhere to the table Kij, there are advantages such as being able to perform precise drawing on the table.
