Abstract: PURPOSE:To make plural types of a jumper wire different in length securable with one unit of a device, by constituting a feeding part, delivering a wire rod as far as the specified length, so as to make a feed rate of the wire rod variable, in case of an electronic parts setting device. CONSTITUTION:A wire rod 2 becoming a rectilinear form at a straightening part 3 is held between a head 8a of a movable side clamper 6 and a movable block 9 and fed toward a fixed side clamper 7 or a cutting part 20 with movements of the movable block 9 and the head 8a by an arm 15 to follow in motion of a main cam 23. At this time, a position or a starting point at the time of movement of the movable block 9 is decided upon a position of a stopper 12 in contact with an outer circumferential surface of a feed rate selector cam 14. Afterward, when the movable block 9 arrives at a terminal of a guide 10, the fixed side clamper 7 clamps the wire rod 2, and the wire rod 2 is fed to the cutting part 20 as far as a distance where the movable side clamper 6 moves, whereby a cutter 19 operates via an arm 24, thus a jumper wire in the specified length is securable. Doing like this, operational smoothness and speediness are well promoted.

Title: Cutting device for long material
Inventor: FUKUHARA KOUJIROU
IPC: B26D1/56
Filed: 1994-05-25
Abstract: PURPOSE:To increase a cut length accuracy and prevent a cut surface from being cut aslant by moving a feed body faster than a long material in a long material advancing direction when the top end of the advancing long material crosses a detector mounted on the feed body and, at the point of time when the mounted detector passes the long material, operating the a cutter located at the rear of the detector so as to cut the material. CONSTITUTION:The position of a photoelectric sensor 303 relative to a cutter 26 is set according to the cutting length Lc of a long material S. Also the ratio of a feed body speed Vh to a long material Vc is set at 1 or more and 2 or less and stored. Then a cutting device is started to move forward the long material S, and its speed is controlled by the output signals from an encoder 18. When the top end of the long material S is detected by a photoelectric sensor 303, a feed body 14 is moved in the same direction as the long material S at a speed of Vh. Because the relative speed is Vh-Wc>0, the long material S will depart soon from the photoelectric sensor 303. At this time, the cutter 26 is operated to cut the long material S. In the cutting, the material S can be cut straight by the offset against a collapse produced in the cut surface of the long material S though it may be cut aslant due to difference in speed.
