Abstract

PURPOSE:To aim at transforming the angle of a square lumber and the like with close tolerances so as to make it shiftable to another course of work, by securing the lumber received in the work receiving mouth of an arm being supported swingably, while setting this fixation free upon gyration of the arm. CONSTITUTION:A square lumber (a) fed from an inclined feeding passage is taken in a receiving mouth 6 of an arm plate 1, which swings aroung a shaft 8, and locked by pressing force of a buffer plate 14 via an adjustable buffer plate 17 operated by a second cylinder 15. A bed frame 21 is provided with a cylinder 12 swingable a around a shaft 12 while the nose of its piston rod 13 is pivotedly attached to the backside of the arm plate 1 of an arm 7. When the first cylinder 12 is operated, a butt plate 11 secured to the arm plate 1 continues to swing till it hits a buffer pin 30, altering the attitude of the square lumber (a) whereby the square lumber (a) is delivered in the longitudinal direction upon release of the fixation by the adjustable buffer plate 17.

The material is pressed and fixed against the inner surface of the jaw on one side of the receiver 11, P, 2, and then the arm is oscillated around the axis to change the angle between the material receiver and the material.
This relates to a material angle conversion device that allows the material to move by moving the presser plate in the return direction after that, and for example, a material such as a square piece of wood that is moving from a path in one direction is transferred to a socket. It is an object of the present invention to provide a device which, after receiving an object and accurately converting its angle, allows movement along another route.

角をも精密にできる等の諸効果をもつ。As is clear from the description of the above-mentioned embodiments, the present invention includes a first cylinder in which an arm having a hollow-shaped material socket is pivotally supported in a freely swinging manner, and the arm is oscillated in at least two angles. Feeding the material to the material receptacle A holding plate such as a movable buffer plate that moves in the direction parallel to the opening within the material receiving port is moved by the second co-cylinder, and the material is clamped between one jaw of the receiving port and the holding plate t. Since the material is fixed in place and does not move when the arm is operated to change the angle, it is possible to accurately change the angle of the material. Further, the above-mentioned angular swinging and movement of the presser plate are controlled by respective cylinders,
In particular, since the material is fixed by the presser plate, the stroke of the rod of the second cylinder does not need to be changed depending on the thickness of the material, as long as the material itself is strong. It has various effects such as being able to accurately bend the angle of a material whose thickness is successively changed.
