Description

  The present invention relates to a cutting machine that cuts sheet-shaped dough according to cutting data while sucking and holding the sheet-like material on a conveyor-driven cutting table.

  2. Description of the Related Art Conventionally, parts for sewing clothing and the like are generated by cutting a sheet-like material such as a cloth. In a cutting machine that cuts fabric according to cutting data created in advance, a cutting table that sucks and holds the fabric material is configured by a conveyor drive system that can also transport the fabric in order to efficiently perform cutting (for example, , See Patent Document 1).

  In the conveyor-driven cutting table, the carry-in table is used to prevent the dropping of the dough material and parts between the carry-in side of the dough material before cutting and the unloading side of the cut material such as parts and remaining material cut from the dough. And the carry-out table must be covered respectively. The conveying force of the conveyor-driven cutting table does not act on the surfaces of the carry-in table and the carry-out table. Therefore, even if the process of sucking and holding the dough material on the cutting table is automated, the process of loading the dough material onto the cutting table from the carry-in side before cutting, and the cut material after cutting from the unloading side. The removal process requires manpower.

Fabric materials such as fabric have air permeability, so when a plurality of sheets are laminated on a spread table and loaded into a cutting table of a cutting machine, the laminated surface is made of a non-breathable synthetic resin such as polyethylene. Cover with a thin sealing sheet. When the dough material laminated on the cutting table is sucked, the suction force acts on at least the uppermost sealing sheet and can hold the entire laminated dough material. Moreover, when the surface of the cutting table is formed with a bristle brush as in Patent Document 1, an underlay sheet is laid on the lowermost layer of the fabric material so that the fabric material does not fall between the bristles. Keep it.
Japanese Patent No. 2955796

  The sealing sheet covering the dough material occupies a wider area than the outer periphery of the dough material. There is a level difference between the surface serving as the conveyor of the cutting table and the surfaces of the carry-in table and the carry-out table. If the dough material is carried onto the cutting table while being conveyed, the sealed sheet can be easily carried in at least near the start end of the carry-out table until it reaches a step.

  When carrying out the material to be cut such as parts after cutting and the remaining material, since the sealing sheet is thin, the tip tends to stagnate in the vicinity of the step where the cutting table is switched to the carry-out table. If the dough materials to be cut are stacked and the length of the sealing sheet leading is short, it is possible to extrude the sealing sheet including the sealing sheet and carry it on such a step by conveying the subsequent portion by the conveyor. However, if the part where the sealing sheet precedes the material to be cut is long, the amount of stagnation of the sealing sheet near the step increases, and it is difficult to pass through the step even if the sealing sheet is pushed out. In particular, when the material to be cut is carried out while being sucked by the cutting table, the cut sheet is not sucked by the carry-out table, so that the sealing sheet is difficult to get over the step and is more likely to stagnate. If the sealing sheet stagnates near the step, the material to be cut cannot pass.

  An object of the present invention is to provide a cutting machine capable of smoothly discharging a material to be cut after cutting.

The present invention has a conveyor driven cutting table whose surface is air permeable, a cut material formed by placing a sheet-like material on the cutting table and covering it with a non-breathable sealing sheet In a cutting machine that cuts according to input data while sucking and holding,
A non-breathable carry-out table provided on the carry-out side of the cutting table, the start end side covering the end of the cut table;
The front end portion of the sealing sheet that is provided so as to approach the terminal end side of the carry-out table and extends forward from the front end of the dough material in the conveying direction in a state where the front end of the dough material does not reach the start end of the carry-out table, And a conveyor type pick-up table capable of being sucked and conveyed.

Further, in the present invention, the end side of the carry-out table has a shorter length on the carry-out side than the support table that supports the cutting table and the carry-out table on both sides,
The tip of the pickup table is connected to the terminal end side of the carry-out table in a state of biting into the inside of the support table.

  In the invention, it is preferable that the pickup table includes a suction chamber disposed in the vicinity of a tip approaching the terminal side of the carry-out table.

Further, in the present invention, the pickup table further includes a conveyor belt provided with suction holes dispersed in a non-breathable material,
The suction chamber applies a suction force to the surface of the pickup table through a suction hole of a conveyor.

Further, in the present invention, the height of the surface that performs the conveyance by the pickup table is lower than the surface of the carry-out table,
An inclination approaching the surface of the pickup table is provided on the end side of the carry-out table.

  According to the present invention, of the material to be cut, the leading end portion of the non-breathable sealing sheet covering the fabric material can be sucked and conveyed by the conveyor type pickup table approaching the end side of the non-breathable carry-out table. Therefore, the material to be cut can be discharged smoothly. Even if the sheet is conveyed while being suctioned by the cutting table, the front end of the sealing sheet is conveyed by the pickup table and pulled out, so that it can be smoothly discharged beyond the step between the cutting table and the carry-out table.

  Moreover, according to this invention, the front-end | tip of a pick-up table is connected in the state which bites into the inner side of the support stand which supports a cutting table and a carrying-out table on both sides. Since the distance between the cutting table and the pickup table sandwiching the carry-out table can be shortened, the sealing sheet can easily exceed the carry-out table.

  Further, according to the present invention, the suction chamber is disposed in the vicinity of the tip where the pickup table approaches the end side of the carry-out table. Even if the front end of the sealing sheet drawn from the material to be cut on the cutting table reaches only the region near the front end of the pickup table, it can be efficiently sucked.

  According to the present invention, the suction force can be applied only through the suction hole in the region where the suction chamber is provided in the non-breathable material conveyor. Thus, the suction force can be reliably applied.

  Further, according to the present invention, the transition can be smoothly performed without reducing the gap or step of the joint from the carry-out table onto the pickup table having a curved tip at the tip, and without providing a connecting plate or the like separately.

  FIG. 1 shows a schematic configuration on the carry-out side of a cutting machine 1 according to an embodiment of the present invention. FIG. 1A shows a partial plan configuration, and FIG. 1B shows a cross-sectional configuration viewed from the section line II in FIG. In the cutting machine 1, a cutting table 3 is formed on the upper part of the support base 2. On the surface of the cutting table 3, a cloth material 4 such as a cloth is placed in a laminated state. The cutting table 3 is formed at the tip of the bristles 5 on the surface. The bristles 5 are erected from a bristle block 6 made of synthetic resin or the like, and also have flexibility to escape from the blade edge when cutting the dough material 4 by piercing the cutting blade from above. ing. The conveyor of the cutting table 3 is formed in a chain shape, and a sprocket wheel 7 is provided at the end. The bristle block 6 is arranged on the surface of a chain-like conveyor. While the chain-shaped conveyor rotates around the sprocket wheel 7 and is turned upside down, the end of the bristle block 6 passes through the outer periphery of the sprocket wheel 7 with a larger radius of rotation than the center.

  On the discharge side of the cutting table 3, a carry-out table 8 is provided so as to cover the vicinity of the sprocket wheel 7 on the start end side. On the start end side of the carry-out table 8, the height of the surface is higher than the surface of the cutting table 3 so that a conveyor having a large turning radius can be reliably covered in the vicinity of the sprocket wheel 7, and a step is generated. The conveyor on the side of the cutting table 3 is accommodated in the suction chamber 9, and suction force on the surface of the cutting table 3 is generated by exhausting the suction chamber 9. In order to surely hold the dough material 4 by suction on the cutting table 3, the surface of the dough material 4 is covered with a sealing sheet 10 which is non-breathable and made of a thin polyethylene film or the like.

  A pickup table 11 is disposed on the downstream side of the carry-out table 8 of the cutting machine 1 and serves as a work table for taking out a material to be cut such as parts and remaining material cut from the dough material 4. In the pickup table 11, the conveyor belt 13 is stretched between the driving roller 14 and the driven roller 15 on the surface side supported by the support 12.

Pull out to the suction area. The conveyor belt 13 is conveyed while the suction force from the suction chamber 19 is applied to the sealing sheet 10 in this suction region, and the cutting table 3 is also conveyed. If it is conveyed while being sucked, the sealing sheet 10 gets over the carry-out table 8 and smoothly moves from the cutting table 3 to the pickup table 11. Since the action of the suction force by the suction chamber 19 is performed only on the area on the carry-out table 8 side, even when only the vicinity of the front end of the sealing sheet 10 is applied on the pickup table 11 as shown in FIG. Can be aspirated.

  In addition, since the sealing sheet 10 covering the dough material 4 is also wider than the dough material 4, even if a material to be cut such as parts reaches the suction area, suction to the sealing sheet 10 is performed at least at both ends in the width direction. Is called. Therefore, in particular, when the material to be cut is conveyed while being sucked on the cutting table 3 side, it is preferable to continue the suction even if the material to be cut gets over the carry-out table 8 and is conveyed onto the pickup table 11.

  FIG. 2 shows a planar configuration in the vicinity of the connection portion between the carry-out table 8 and the pickup table 11. The carry-out table 8 becomes a comb tooth portion 8a inclined at the front end side and a guide portion 8b inclined also at the terminal end side.
