The present invention relates to a fabric cutter that can continuously and appropriately cut a fabric.

Normally, fabrics (especially towels) are continuously woven, and if necessary, cutting them by a certain width has been cut to the proper length by hand, which not only hinders uniformity of the product, but also waste of manpower and work time. Was enormous. In addition, since the cut part is not cut cleanly, which leads to waste of the fabric and is directly connected to the product defects, the present invention has been developed to provide a device capable of continuously cutting the woven fabric by a predetermined width, and the following accompanying drawings and Together, the present invention will be described in detail.

FIG. 1 is a schematic side view of an apparatus showing an embodiment of the present invention, wherein a motor roller 2 for periodically supplying a woven fabric (a) by a predetermined amount is arranged on the side of the base (1), and the fabric ( A photo sensor 3 for measuring the length of a) is provided below the ship side.

The fabric (a) supplied by the motor roller (2) is given an appropriate tension by the tension roller (4), and the fabric (a) supplied to the upper surface of the base (5) is an expander (7) (7 '). ) Is lowered and then stretched from side to side in the bloated state to impart proper tension to the fabric (a) and simultaneously correct the left and right sides of the fabric (a). When the pressing of the fabric a while tensioned by the proper pressure is completed, a circular cutter provided laterally on the base 1 in a state in which the stopper 6 before and after the base 5 is pressed and fixed to the fabric a and before. The fabric (8) is cut while rotating at a high speed, and the cut fabric is sandwiched by a gripper (9) on one side of the body and laminated on the lift (10). One side of the lift 10 is attached to the optical sensor 11 is to automatically lower the lift 10 by measuring the load of the fabric to be cut, stacked in a continuous operation. When the lift 10 descends to the bottom, the worker transfers the fabric a loaded on the lift 10 for the next work, and the work is completed. Fabric cutting machine of the present invention is a continuous operation as described above with reference to Figures 2 to 4 will be described in detail the configuration.

Figure 2 is a perspective view of the fabric clamping portion (A) of the present invention, a support frame 12 is placed on the upper surface of the base (5) a plurality of guide bars (13, 14) between the support frame 12 It is installed, the expander (7) is installed in the lower guide bar 13 so as to reciprocate from side to side. That is, the fixed table 15 and the floating table 16 of the left and right expanders 7 are connected to the air cylinder 17 so that the piston 17 'of the air cylinder 17 of the fixed 15 is extended or contracted so that the floating table 16 ) Is configured to reciprocate left and right, the nip 20 is connected to the piston 18 'of the air cylinder 18 at the bottom of the flow table 16, the fabric by the elastic action of the piston 18' of the air cylinder 18 (a) has been sandwiched or released. On the other hand, the upper guide bar 14 is provided with a carriage 21 so as to be movable, and the circular carriage 8 and the cutter driving motor 22 are attached to the carriage 21. Before and after the support frame 12, a stopper 6 for sandwiching the fabric a and the fabric is connected to the piston 19 'end of the air cylinder 19, and the fabric is stretched or sandwiched by the piston 19'. It will be released. The action of each of the air cylinders 17, 18, and 19 is performed by the thickness t monitoring sensors 23 and 23 ′. That is, when the fabric (a) is supplied to the upper surface of the base (5), the left and right thickness sensors (23, 23 ') detect this and the vertical air cylinder 18 of the expander (7) is stretched and supplied the fabric (a) After pressing the left and right sides of the horizontal air cylinder (17) is stretched and tightly sandwiches the fabric (a) and at the same time to correct the lateral properties of the fabric, that is, the left and right, the air cylinder (19) of the stopper (6) By stretching and sandwiching the fabric (a) it is to complete the preparation for cutting.

In FIG. 3, the operation state of the carriage 21 and the stopper 6 in which the expander 7 and cutter 8 which are main parts of this invention are mounted is shown. The expander 7 which can be moved and fixed in accordance with the width of the fabric (a) is fixed to the guide bar 13 to the left and right by the width of the fabric (a) to be cut core, so that the pincer 20 under the fluidized bed 16 is 1 Since the cylinder 17 'of the cylinder 17 of the holder 15 is contracted in the fabric holding state by car, the holding plate 20 is moved to the left and right, so that the fabric a is tensioned and the horizontal line of the fabric is also The correction is made. And the circular cutter (8) of the carriage 21 is to cut the fabric (a) quickly and cleanly while rotating the fabric (a) in a tense state. At this time, the stopper 6 is also pressed down the tip of the towel (a) in the lowered state, of course.

Figure 4 is a side view showing a lift 10 of the present invention, the lift 10 detects the loading amount of the cut fabric (a) as described above by the optical sensor 11 and gradually descends by a predetermined width in accordance with the loading amount The lift 10 is configured to be lifted as a lift motor and a plurality of chain gears and chains. On the other hand, the cut fabric is pinched when the gripper 9 pinches the fabric a to move to the ship side along the guide rail in order to drop in place of the lift 10 and then is positioned on the upper surface of the lift 10. The fabric (a) will be released. And the fabric cutting machine of the present invention attached to the lower caster to provide the ease of movement, the circular cutter also provides the ease of replacement for polishing, the circular cutter is also easy to replace for polishing, the number of sheets After inputting the number of sheets, the job is configured to be completed when the cutting operation is completed. Since the program and circuit configuration of the present invention uses a known sequence control circuit, detailed description thereof will be avoided.

The present invention can be carried out as described above is a continuous supply of fabric, sandwiching, cutting, conveying, lamination can be carried out the fabric cutting work efficiently, organically the stopper, expander, cutter, etc. for cutting the fabric Combined and operated, more precise cutting can be performed. In addition, the supply of the fabric and the lamination of the cut fabric is sensed by the photosensor and the light sensor to drive the motor roller and the lift, thereby ensuring the efficiency of the work without additional manpower consumption.

The technical scope to be protected in the present invention will be mentioned in the following appended claims, but the present invention may be embodied in the present invention even if the structure is partially changed or replaced, or the form is changed in part. Will be included in the technical category.
