Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cutting table used when manufacturing large quantities of clothing.

When manufacturing large quantities of clothing, the fabric is stacked in multiple tiers on a horizontal cutting table using a spreading machine or by hand, folding the fabric at both ends of the cutting table, and then placing a plow on top of the fabric. The method used is to set a cutting line so that the fabric does not move, and then cut the fabric using a cutting machine.

In the case of such a conventional method, if the fabrics are simply stacked on a horizontal cutting table, the weave 2 of the fabric 1 in the weft direction will not be straight as shown in Figure 1, but will be uneven. If you create a cutting line 3 and cut fabric along this line and silicate clothing such as a skirt, when you hang or wear this clothing, it will form a straight line when silicate. The stitches are crooked and the pattern is crooked, making it extremely unsightly.

There is also a needle-stretching method in which the fabric is suspended by piercing the upper edge of the fabric with multiple needles placed along the top of a vertical cutting table; There is a problem in that it is not possible to spread a large amount of paper because the gaps sag and become wavy.

The purpose of this invention is to make it possible to manufacture accurate clothing by neatly aligning fabrics stacked on a cutting table and passing the grain through the fabric. Note that ``through the grain'' is a term used in silicic acid to mean that the weave is aligned in a precise straight line.

That is, in this invention, a presser frame is provided on one side of the cutting table which can be freely converted from horizontal to vertical, and presses one side of the fabric stacked in multiple tiers on the cutting table. To provide a cutting table configured to allow fabric to hang down and pass through the grain by standing the cutting table with a presser frame on top.

The details of the cutting table of the present invention will be explained below based on an embodiment shown in the accompanying drawings.

In the figure, numeral 11 indicates a cutting board, which is placed on a frame 12. A pair of protrusions 13 are fixed near both ends of the lower surface of the cutting table 11, and the protrusions 13 are rotatably attached to bearings 14 at both ends of one upper side of the frame 12 by shafts 15.

16 is a cylinder for raising and lowering the cutting table 11, and is operated by air or hydraulic pressure. The rear end of this cylinder 16 is rotatably attached to a bearing at the lower part of the frame 12 by a shaft 17, and the upper end of a piston rod 18 protruding from the tip of the cylinder 16 is rotatably attached to the lower surface of the cutting table 11 near the front part by a shaft 19. Store it freely.

Reference numeral 2o denotes a presser frame provided on the rear side of the cutting table, and this frame 20 rotates a plurality of brackets 21 provided at the lower part of the frame 20 downward around a shaft 21' on the rear side of the cutting table 11 by means of a shaft 22. The bearing mounting base 23' is rotatably attached to the bearings 23 provided in this way.

24 is a cylinder mounted on a bracket 25 provided at the rear of the bearing mounting base 23' of the cutting table 11, and is operated by air or hydraulic pressure, and its piston rod 26 is connected to a crank 27 fixed to the shaft 22 to perform the above-mentioned operation. The presser frame 20 is designed to be raised and lowered. A locking device is provided at the shaft 21/ of the mounting base 23/ when the base 23' is horizontal.

The apparatus of the present invention has the above structure, and the cutting table 11 is made horizontal as shown by the solid line in FIG. 3, and the bearing mounting table 23' is also made horizontal and locked to the cutting table 11. With the presser frame 2o rising rearward and upward as shown by the chain line,
Using a spreading machine (not shown), the fabric 28 pulled out from the original fabric is stacked on the cutting table 11 while reciprocating (but at this time, care is taken to ensure that the warp threads of the fabric 28 are parallel to the presser frame 2o.

When the desired fabric 28 is stacked in this way, the cylinder 2
4 to lower the presser frame 2o as shown by the solid line in FIG.

In this state, the cylinder 16 is operated and the cutting table 11 is erected as shown by the chain line in FIG. Although the chain line in FIG. 3 indicates that the frame is vertical, in reality, when the cutting table 11 is rotated more than 90 degrees from the horizontal position in FIG. The fabric 28, which is strongly clamped on one side by the cutting table 11 and the cutting table 11, hangs down vertically, but the cutting table 11 is rotated by more than 90 degrees. It hangs down vertically apart from the cutting table 11, leaving a portion intact.

Therefore, all the weft stitches of the fabric 28 are vertical and pass through the grain of the ground, so if the cutting table 11 is returned to its original horizontal position, the weft stitches in the fabric field will be woven vertically, as shown in Figure 2. Eyes 29 are aligned correctly. Next, operate the cylinder 24 to press the presser frame 2.
0, loosen the lock on the bearing mounting base 23', and lower the base 23', bracket 25, cylinder 24, presser frame 20, etc. below the cutting table 11, and then cut the weighted fabric as before. By keeping the fabric 28 stationary and providing a cutting line 30 and cutting the fabric 28 along this line, accurate clothing with the correct weave and pattern can be produced.

As described above, the cutting table of this invention is provided with a presser frame on one side to press one side of the fabric stacked on the cutting table in a horizontal state, and the cutting table is erected so that the presser foot □ member side is on top of the fabric. The extremely simple operation of letting the fabric hang down and then setting up the cutting table allows the opening of the fabric to pass through, making it the same as cutting the product while wearing it, resulting in excellent clothing.

The illustrated embodiment has a mechanism in which the rotation of the cutting table and the operation of the presser frame are performed by air, hydraulic cylinders, etc.; You can also do this.

FIG. 1 is a plan view of a conventional cutting state, FIG. 2 is a plan view of a state of cutting by the cutting table of the present invention, and FIG. FIG. 4 is a partially cutaway side view of the same, and FIG. 4 is a partially cutaway front view of the same.
