Description

Detailed Description of the Invention (a) Industrial application field A device related to a cutting machine that can continuously vary the cutting length of raw material (b) Conventional technology One of the materials used for flexible containers, polypropylene-based linen material The length of the fabric was measured and cut by a person using an electric trowel each time. (c) Problems that the invention aims to solve: There is a limit to the efficiency of cutting by humans, and the cut dimensions also vary depending on the person. It is an object of the present invention to solve the above problems by automating the cutting operation. (d) Means for solving the problems This invention will be explained based on the drawings. It consists of a cutting section consisting of a nichrome wire (6), a spring (7) that presses the original fabric, a torque motor (5) that moves these up and down, and a sequence section (Fig. 4) that controls the overall operation (e). First, to explain from the hardware side, the upper and lower rollers (2, 12) hold the material, and when the lower rubber roller (2) connected to the motor and belt (4) reaches the setting position, the motor (3) stops. The cutting section descends, and the spring section (7) first presses both sides of the nichrome wire (6) in contact with it, and then the nichrome wire descends to melt and cut the original fabric.This operation is repeated the number of times set on the counter. On the software side, a limit switch (11) that uses the pulses emitted when the rotary encoder (10) rotates as a sensor and inputs the pulses to the counter confirms that the cutting section is rising when the start button on the control panel is pressed. ) Confirm that the nichrome wire switch is on. If the relay is working, the motor (3) will operate. At the same time as this operation, the rotary encoder that is in contact with the roller rotates and starts counting when the set value is reached. The motor stops and the torque motor (5) descends.The lower limit switch (11)
), the torque motor stops and stands still according to the set timer.After the timer is up, the torque motor rises and is stopped by the upper limit switch.The above operation is repeated for the number of counters set.(f) Effects of the inventionThis invention As explained above, the dimensions can be changed arbitrarily using the cutting counter, and the number of sheets can also be set arbitrarily.For this reason, it is several times more efficient and accurate than cutting by humans.
