Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device that picks up two round bar-shaped objects at a time and feeds them onto a conveyor at regular intervals, and is particularly applicable to a two-bar electric upsetter. It is suitable.

Upset processing is a type of upsetting forging in which one end of a predetermined length of birch wood is fixed in a die, and the end of the birch wood that protrudes from this is compressed and expanded in the direction of the grain. Often used for molding.

According to this processing method, the flow (grain flow lines) of the grain structure along the processing direction is continuous, so that it is possible to form products that are resistant to impact stress. By the way, most of the conventional electric upsetters that perform this type of upset processing are single-pole machines that process a single piece of Japanese bamboo between a pair of electrodes, but recently, due to the demand for improved production efficiency, This led to the development of an electric upsetter. Along with this, it has become necessary to simultaneously supply two camellia strips at a predetermined interval between a pair of electrodes. A conveyor in which carriers for holding objects are formed at regular intervals and intermittently transports the objects so that these carriers always stop at predetermined positions, and a conveyor installed directly above the conveyor and conveying the objects to the two carriers. a sorting guide that guides the two objects to be transported one by one at the same time; an input cage that is installed above the sorting guide and drops the two objects to be transported toward the sorting guide; A diagonal guide plate whose lower end is connected to the loading gate and which guides the two objects to be transported toward the loading gate; A tilted war calendar board located below the upper end of the plate, and moved up and down between the upper end of the tilted guide plate and the lower end of this diagonal plaque to position it at the lower end of the tilted battle board. By providing a bamboo material feeding device comprising a transfer member that feeds the two objects to be transported to the upper end of the inclined guide plate, the object to be transported in the shape of a round bar can be transported once. Two pieces are taken at a time and fed onto a conveyor at regular intervals. Hereinafter, the bamboo wood feeding device according to the present invention will be described as a dual-capture electric forpsetter'.
An embodiment to which this is applied will be described in detail with reference to FIG. 1 showing its planar shape and FIG. 2 showing its D-0 cross section.

Also, similar to the inclined guide plate 25 which is fixed to the side plate 15 of the other input gate (on the right side in the figure) and feeds the two objects 11 toward the input gate, The two objects 11 are moved along the inclined guide plate 25 and the loading gate 18 until they come into contact with the positioning stopper 22, and are stopped at a predetermined position. At the bottom of the upper end of the inclined guide plate 25 whose lower end is connected to the input gate group 8, the left and right side plate turtles 5 are connected, and the equipment 26, which together with these side plates 15 constitutes the main body of the device, is installed. The lower end of a vertical lattice-shaped inclined teaching pupil plate 27 supported so as to be movable back and forth is located at the lower end of the inclined teaching pupil plate 27.
A stopper 28 is formed to stop the conveyed object turtle 1 rolling down from the upper end of the conveyor belt 7 .

Further, directly above the lower end of this slanted lectern board 27, a holding plate 29 for lining up the objects S to be transported in a line on the slanted podium board 27 is connected to a support block 30 fixed to the side plate 15.
An adjustment shaft 31' is rotatably attached to the support plate 27, and by rotating the adjustment shaft 31 in accordance with the position of the transported object li, the presser plate 29 and the tilt calendar plate 27 are screwed together and supported. It is possible to arbitrarily change the interval between the two. The two objects 11 to be transported are arranged so that they can pass upward between the presser plate 29 and the stopper 28 of the forehead oblique laminate 27.
An adjustment shaft 32 that moves the Fussha Sekyo board 27 back and forth in accordance with the diameter of It is in a screwed state with a screw block 35 protruding from the side. The transfer member that lifts the two objects 11 located at the lowest position of the slanted platform board 27 to a level equal to or higher than the upper end of the sloping guide plate 25 and guides them onto the slanted guide plate 26 is the main one. In the embodiment, it is composed of a fluid pressure cylinder 37 fixed to the equipment 36 and a pusher 38 that is raised and lowered by the operation of the fluid pressure cylinder 37, and the objects 11 to be transported are moved two by two to the holding plate 29 by the raising and lowering movement of the pusher 38. The guide plate 25 passes between the lower end of the guide plate 27 and the stopper 28 of the inclined bush placing plate 27, and is fed into the upper end of the inclined guide plate 25 one after another. In this embodiment, the length of the transported object 11 is adjusted according to the length of the transported object 11.
