[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting machine for cutting a part to be cut in accordance with cutting data while vacuum-suctioning and holding a cloth to be cut on a cutting table. The present invention relates to an apparatus and a method for supplying an air cloth-coated sheet to a cutting machine for supplying a functional coated sheet.

[0002]

2. Description of the Related Art Conventionally, in a cutting machine, in particular, an automatic cutting machine, a cloth to be cut is held on a cutting table while vacuum suction is performed, and the cloth is freely moved on the cutting table in accordance with the cutting data. The outer shape of parts is cut. Since the dough to be cut is generally not impermeable, simply placing the dough on a cutting table cannot be sufficient. For this reason, the dough is further covered with an air-impermeable sheet to ensure that the vacuum is maintained. As the cloth covering sheet, for example, a synthetic resin film such as polyethylene or vinyl chloride is used.

FIG. 14 shows a simplified configuration of the prior art disclosed in Japanese Patent Publication No. 62-25785. The cutting machine 1 has a cutting table including a processing table 2, an upstream transfer table 3, and a downstream transfer table 4. The cutting carriage 5 includes rails 2 provided on both sides of the processing table 2 and the transfer tables 3 and 4 in the width direction.
a, 3a, and 4a. The cutting carriage 5 is provided with a cutting head 6 movable on the cutting carriage 5 in the width direction, and a cutting tool 6 for cutting the cloth.
a is provided. The label carriage 7 can travel on rails 2 a, 3 a, 4 a provided on both sides of the processing table 2 and the transfer tables 3, 4, similarly to the cutting carriage 5. The label carriage 7 has a function of giving a label to the cloth for part identification while moving. The label carriage 7 is further provided with a holding device 8 such as a cloth sheet. Above the vicinity of the boundary between the processing table 2 and the transfer table 3 on the upstream side, a cutting device 9 is provided.

At an end of the transfer table 3 on the upstream side, a raw material sheet 10 and a coated sheet raw material 11 in which a cloth sheet and a cloth-coated sheet are respectively wound are respectively supported by shafts. Nipping device 8 provided on label carriage 7
Performs a rolling operation in which the front end of the dough sheet unwound from the raw dough sheet 10 is pinched and the dough sheet is spread on the working table 2 by a predetermined length while moving from the transfer table 3 to the working table 2. When the elongation of one dough sheet is completed, the sheet is cut by the cutting device 9 and the elongation of the dough sheet is repeated to form the laminated sheet 12 on the processing table 2. After a predetermined number of laminated sheets 12 have been formed, the clamping device 8 of the label carriage 7 clamps the leading end of the cloth-coated sheet unwound from the coated sheet material 11 and places the laminated sheet placed on the processing table 2. The sheet 12 is covered.

[0005]

In the prior art as shown in FIG. 14, after the fabric sheets are spread and stacked on the processing table 2 by using the same label carriage 7 and the holding device 8, the laminated sheet 12 is formed. To cover with a cloth covering sheet. When such a spreading operation is being performed, the cutting cannot be performed by operating the cutting carriage 5. In this prior art, the transfer tables 3 and 4 can be moved independently of the processing table 2 in a direction perpendicular to the plane of FIG. 14, and are stacked on one processing table 2 by using a plurality of processing tables 2. It is possible to cut the laminated sheet 12 already formed on another processing table 22 while forming the sheet 12 by spreading.

Claims (10)

(57) [Claims] 1. An air-impermeable coating sheet covering the surface of a cloth is supplied to an automatic cutting machine which cuts parts from the cloth according to cutting data while sucking and holding the cloth on a cutting support surface of a conveyor drive system. An apparatus for supplying, comprising: a support means for supporting a roll on which a covering sheet is wound, the support means being erected on both sides in the width direction of the automatic cutting machine on the side of loading the dough into the cutting support surface; Feeding means for feeding the coated sheet from the rolls supported by the conveyor belt to the cutting support surface driven by the conveyor, and feeding the coated sheet to the cutting support surface. 2. The apparatus for feeding a cloth-coated sheet to a cutting machine according to claim 1, wherein a cutting means for cutting the coated sheet to be fed is provided below the feeding means. 3. A guiding means for guiding a covering sheet fed from the feeding means in a conveyor driving direction of a cutting support surface.
An apparatus for feeding a cloth-coated sheet to the cutting machine described in the above. 4. The cloth covering sheet for a cutting machine according to claim 3, wherein said guiding means guides and guides the covering sheet by blowing air from below the feeding means toward the cutting support surface. Feeding device. 5. The apparatus according to claim 3, wherein the guide means guides the guide sheet in the direction of the cutting support surface while contacting the fed cover sheet. 6. A spreading machine having means for unloading the stretched dough is provided upstream of the automatic cutting machine on the loading side, and a detecting means for detecting the dough carried in from the spreading machine; 6. The control method according to claim 1, further comprising a control means for driving the conveyor and feeding the cover sheet from the feeding means in association with the unloading speed of the reversing machine when the cloth is detected by the means. A device for feeding a cloth-coated sheet to a cutter according to any one of the above. 7. An air-impermeable coating sheet covering the surface of a fabric is supplied to an automatic cutting machine which cuts parts from the fabric according to the cutting data while sucking and holding the fabric on a conveyor-driven cutting support surface. A method for feeding, wherein a roll on which a covering sheet is wound is supported above a conveying path of the dough to the cutting support surface, and the covering sheet is fed out from the roll and guided and guided in the direction of the cutting support surface. A method of supplying a dough-coated sheet to a cutting machine, wherein the dough is covered with a covering sheet at a payout speed associated with a dough carrying-in speed. 8. The method according to claim 7, wherein the guiding is performed by driving the conveyor while sucking the cutting support surface. 9. The method according to claim 7, wherein the guiding is performed by ejecting air from a carry-in path of the dough to the fed out cover sheet. 10. A spreading machine which can carry out the stretched dough is installed on the upstream side of the dough carry-in path, and the spreading condition and the cutting condition are set according to the cutting data. The machine is interlocked according to the set rolling conditions and cutting conditions, and the coated sheet is supplied so that the stretched fabric is unloaded from the spreading machine, sucked in by the cutting support surface, and loaded in, while covering the entire fabric. The method for supplying a cloth-coated sheet to a cutting machine according to any one of claims 7 to 9, wherein:
