A cloth loading member (sheet) (4) on which the cloth (5) to be cut is positioned and which is used for cutting the cloth by the cutters (31, 41) is made of a moquette.  Since the moquette is flexible, the cutters can be substantially prevented from receiving the damage resulting from the contact thereof with the cloth.  Furthermore, since the ends of plumes of the moquette are twined with the warps and wefts of the cloth, and the cloth to be cut is held at a predetermined position, the cutting accuracy of the device can be improved.

Description

  The present invention relates to an apparatus for easily and reliably cutting a dough, and an apparatus for simply and reliably cutting and laminating a dough.

  Clothes for clothes and Japanese clothes are supplied as very long rolls of raw material. After this raw material is cut into a predetermined length, it is further cut into various types of parts and processed into desired parts through a sewing process. It is marketed as. For example, in the case of suit clothing, the fabric worn by suit 1 is less than 2 meters long and reaches about 1 meter wide. Various methods have been proposed for automatically or semi-automating the work of laminating fabrics cut from a roll-shaped raw fabric because the fabric of this size is light in weight but large in area and difficult to handle.

  In the cutting step, the dough is located on a sheet placed on a cutting table or on a conveyor belt, and the dough is cut with a cutting cutter. Conventional sheets and conveyor belts are usually made of hard resin or coated with hard resin, and cutters that cut the fabric in the cutting process frequently come into contact with the sheets and conveyor belts, causing the cutter's cutting ability to deteriorate or break. Therefore, it is necessary to frequently replace the cutter, which is a problem in terms of cost and work efficiency.

  In order to eliminate this drawback, the present applicant installed a synchronous member that runs synchronously with the cutter and has a concave groove on the upper surface between the dough and the conveyor belt so that the rotary blade and lower blade of the cutter can move. An apparatus has been proposed in which the dough can be cut without entering the concave groove of the synchronizing member and contacting the conveyor belt (Patent Document 1). This method is epoch-making in terms of cutter protection, and the replacement frequency can be greatly reduced. However, this apparatus has a restriction that the synchronizing member is synchronized with the cutter, and thus the complexity of the apparatus cannot be avoided.

A method of using a bristle block as an alternative to a sheet that comes into contact with the fabric is known (Patent Document 2). This bristle block is made of a hard resin having a height of 5 to 10 cm, and is used to suck a large number of laminated fabrics from below, and air is sucked downward from the space between the bristle blocks. In this apparatus, since the cutter contacts the bristle block made of hard resin, further cutter damage occurs.
Further, when the conventional dough is cut, the dough slips due to the fact that the dough is merely placed on a sheet or a conveyor belt, and the accuracy is not sufficient.
Table 2005/005709 Japanese Patent Publication No.57-58277

  The object of the present invention is to solve the drawbacks of the prior art and to provide an apparatus capable of cutting and laminating fabrics with high accuracy and with a simple structure without substantially damaging the cutter.

A sheet 4 is coated on the cloth cutting table 3 so as to cover the entire surface thereof, and the cloth 5 is positioned on the upper surface of the sheet 4 leaving a peripheral edge.

  As shown in FIG. 4, the sheet 4 has a configuration in which a large number of fluff 9 is planted and raised on a fabric base 8 in which warps 6 and wefts 7 are woven. 4 shows an example in which the fluff 9 is planted only on the warp 6 among the warp 6 and the weft 7 for simplification, but it is actually preferable to raise the fluff on both the warp and the weft.

A pair of X guide rails (carriage rails) 10 are provided along the side surfaces of the two main body frames 2, and a pair of carriages 11 can run on the X guide rails 10. A hollow and rectangular connecting member 12 is installed between the carriages 11, and a Y guide rail (cutter head guide rail) 13 is provided along a side surface of the connecting member 12.
A cutter head 14 is attached to the Y guide rail 13 and can travel along the connecting member 12.
The cutter head 14 is provided with a longitudinal frame 15 longer than the longitudinal length of the connecting member 12, and the frame 15 is installed on one side surface by a guide 16 having a laterally concave cross section. 13 can run.

A pair of mounting members 17 are installed on the other surface side of the upper portion of the frame 15 so as to be spaced apart from each other vertically, and a guide shaft 18 is bridged between the mounting members 17. A slide bearing 19 is fitted to the guide shaft 18 so as to be movable up and down, and a vertical movement frame 20 is fixed around the bearing 19 so as to move up and down together with the bearing 19. The vertical movement of the frame 20 is performed by a cutter vertical cylinder 21.
The vertical motion frame 20 is provided with a cutter turning motor 22, and the rotation of the motor 22 is transmitted to a hollow center shaft 25 supported by a center bearing 24 by a cutter turning pulley 23. This is transmitted to the lower blade moving air joint 26 fitted in the shaft 25. A blade frame 27 is fixed to the other end side of the center shaft 25 of the air joint 26.

A blade shaft 28 is fitted into the lower end of the blade frame 27 and a slightly upper blade hole, and a rotary blade 31 having a round blade shape is rotatably mounted around the blade shaft 28 by a blade bearing 29 and a blade retaining nut 30. Yes. Although the rotary blade 31 is a polygonal blade in the illustrated example, it may be a round blade.
A blade rotation motor 32 is fixed to a side slightly below the center shaft 25 of the blade frame 27, and the rotation of the blade rotation motor 32 is caused by the motor shaft 33-upper gear 34-belt 35-lower gear 36. The rotary blade 31 is rotated by being transmitted to the blade shaft 28 in order.

  An air hose 37 is connected to the center shaft 25, and the other end of the air hose 37 is connected to a lower blade moving air cylinder 38. A lower blade shaft (fulcrum member) 39 is connected to the lower end of the air cylinder 38, and the lower blade shaft 39 passes through the blade frame 27 and communicates with a lower blade 41 held by a lower blade holder 40. The lower blade 41 and the rotary blade 31 constitute a cutting cutter. The blades constituting the cutting cutter are not limited to the illustrated rotary blade 31 and lower blade 41.

Prior to the cutting of the dough, a sheet 4 made of moquette is placed on the dough cutting table 3, and the dough 5 is placed on the sheet 4. In this state, the tips of a large number of fluffs 9 raised on the base fabric 8 of the sheet 4 come into contact with the lower surface of the fabric 5 and get entangled with the warp and weft of the fabric 5, making it difficult for the fabric 5 on the sheet 4 to move. Yes.
At this time, the rotary blade 31 and the lower blade 41 are located in the upper space of the fabric 5.
Next, when the rotary blade 31 and the lower blade 41 are lowered while maintaining the positional relationship between the rotary blade 31 and the lower blade 41, only the rotary blade 31 first comes into contact with the fabric 5 as shown in FIG. 3A. At this time, the sheet 4 made of moquette is located below the fabric 5 with which the rotary blade 31 comes into contact, and there is a relatively large space between the fluffs 9, and the rotary blade 31 applies tension downward to the fabric 5. In the held state, a cut is made at the cutting start position.

  Next, when the lower blade 41 is rotated downward about the connecting portion with the lower blade holder 40, the lower blade 41 contacts the cloth 5 inside the notch together with the rotary blade 31, as shown in FIG. 3B. In this state, the lower blade 41 and the rotary blade 31 are moved in the X direction or the Y direction by the traveling of the carriage 11 or the cutter head 14, or the cutter head 14 is rotated about the center shaft 25 to obtain the desired fabric 5. The pattern 42 can be cut into shapes. The illustrated apparatus can be used not only for cutting the dough 5 into a pattern having a desired shape, but also for cutting a long original fabric into a square having a predetermined length.

At the time of cutting the fabric, as in the case before the cutting, the tips of a large number of fluffs 9 raised on the base fabric 8 of the sheet 4 come into contact with the lower surface of the fabric 5 and get entangled with the warp and weft of the fabric 5. Since the cloth 5 is difficult to move, the cloth cutting accuracy is improved. The sheet in the conventional cloth cutting device is made of a fabric without fluff or is a resin-coated sheet, so the cloth may slip on the sheet and may not be cut with high precision. In this apparatus, since the fluff of the sheet is intertwined with the fabric fibers, it is possible to realize high-precision cutting without slipping.
Moreover, since the sheet 4 is raised with the fluff 9 on the base cloth 8 with the tip open, there is almost no resistance when the rotary blade 31 or the lower blade 41 in contact with the sheet moves, and the sheet 4 is smooth. Cutting operation can be realized.
