Cutter and method of positioning tip of material to be cut in cutter

Since this is an open matter, no full text was included.

1 is a perspective view of a general horizontal band saw machine as an example of a cutting machine, and FIG. 2 is an explanatory view of the operation of the first embodiment according to the present invention.

Claims (10)

In the vicinity of the cutting position, a main body vise device for trapping and fixing the workpiece, a conveying means for transferring the workpiece toward the cutting position, and a distal end portion of the workpiece disposed at a predetermined distance from the cutting position and conveyed toward the cutting position is detected. A first detecting means for detecting the moving position detecting means for detecting a moving position of the tip of the raw material after the first detecting means detects the leading end of the raw material, a feed speed control means for controlling the conveying speed of the raw material by the conveying means; And a stopper means for freely contacting the tip of the raw material at a predetermined position, a contact detecting means for detecting that the tip of the raw material is in contact with the stopper means and sending a stop signal to the movement speed control means. The transfer vise device according to claim 1, wherein the transfer means is a transfer vise device capable of reciprocating by trapping material, and the stopper means being any of the movable vise jaw in the cutting tool vise device in the cutter or the stopper member configured near the cutting position. Cutter, characterized in that. In the vicinity of the cutting position, a main body vise device for trapping and fixing the workpiece, a conveying means for transferring the workpiece toward the cutting position, and a tip end of the workpiece conveyed toward the cutting position, which is disposed a predetermined distance forward from the cutting position. A first detecting means for detecting the moving position, a moving position detecting means for detecting a moving position of the tip of the raw material after detecting the tip of the raw material, a feed rate control means for controlling a feeding speed of the raw material by the conveying means, and a feeding speed in advance And a deceleration position setting means for decelerating at the set position, and a stop position setting means for stopping the material and the tip portion at a predetermined position. 4. The second deceleration position setting means according to claim 3, further comprising: second detection means arranged between the first detection means and the cutting position to detect the leading end of the workpiece and second deceleration position setting means for setting the deceleration position of the second stage of the feed speed; Cutting machine comprising a. 5. The cutter according to claim 4, wherein the conveying means is a conveying vise apparatus capable of reciprocating by trapping the raw material, wherein the stop position of the raw material tip is a cutting position. A main body vise device for trapping and fixing the material near the cutting position, a transfer vise device for trapping and conveying the material toward the cutting position, a feed speed control means for controlling the feed speed of the material by the transfer vise device, and And a stopper means for freely contacting the tip of the workpiece at a position, and a contact detecting means for sensing that the tip of the workpiece is in contact with the stopper means. A method for positioning the leading end of a workpiece to be cut in a cutter, wherein when the leading end of the workpiece to be transported to the cutting position of the cutter is detected by a detecting means configured a predetermined distance forward from the cutting position, or the detecting means detects the leading end of the workpiece. The position of the tip of the workpiece is reduced by the reduction of the feed speed of the workpiece when the workpiece is discharged by the set distance from the detected position, and the stop of the workpiece when the leading edge of the workpiece comes into contact with the stopper means configured at the predetermined position. A method of positioning a material tip in a cutter, characterized in that for determining. 8. The material tip of a cutting machine according to claim 7, wherein the stopper means is any one of a cutting tool in the cutter, a stopper member configured near the cutting position, or a part of a vise device which catches and fixes the material near the cutting position. Positioning method. In a cutter, a method of positioning the leading end of a workpiece to be cut, wherein when the leading edge of a workpiece to be conveyed toward the cutting position of the cutter is detected by a detection means configured a predetermined distance forward from the cutting position, or the detection means is the leading edge of the workpiece. The moving speed of the work is decelerated when the leading end of the work is batteryd by the first set distance from the position of detecting the stop, and after the deceleration, the feed stops when the leading end of the work is pushed by the second set distance from the detection position of the detecting means. And positioning of the tip of the raw material, wherein the positioning of the tip of the raw material is performed. 10. A method according to claim 9, wherein after the deceleration of the feed rate of the raw material, the feed speed is further decelerated before the leading end of the raw material advances to the second set distance. ※ Note: The disclosure is based on the initial application.
