This is for transferring to the bucket B. The concave base 1 has a bottom surface formed of a horizontal portion, and an inclined surface bent at an obtuse angle with respect to the bottom surface in a bi-extending direction continuously from the bottom surface, and has a trapezoidal cross-sectional area. It is important to have a cross-sectional area where the work Z can be placed. However, the shape of the concave base 1 is not limited to the above shape, and the cross-sectional shape may be circular, elliptical, or polygonal.

The delivery plate 3 thus formed is displaced at an angle corresponding to the diameter and weight of the long material A to be conveyed, so that the long material A is evenly placed on the concave base 1 from the chain conveyor 8. It is intended to be placed.

One end of the rod 4 constituting the mounting means is pivotally supported by the side of the concave base 1. Middle part 1 of rod 4
Reference numeral 7 is connected to a drive cylinder 18, and the drive cylinder 18 is also mounted on the lower side of the concave base 1, so that the rod 4 and the drive cylinder 18 move up and down together with the concave base 1. The rod 4 is pivotally displaced at the other end by the operation of the drive cylinder 18 around the one end 19 pivotally supported by the side of the concave base 1, and when the drive cylinder 18 is extended, the rod 4 moves within the cross section of the concave base 1. When the drive cylinder 18 contracts, it retracts from the cross section of the concave base 1.

When the concave base 1 rises and the long material A sent from the chain conveyor 8 is once received, the driving cylinder 18 is extended and the rod 4 is rotated upward. The position of the rod 4 and the chain conveyor 8 is made close to each other, and the long material A sent out from the chain conveyor 8 does not fall down a high drop, and the rod 4 close to the chain

It is preferable that the distal end of the pressing plate 5 abutting on the workpiece Z is coated with a soft material W, for example, with nylon or the like so as not to damage the outer peripheral surface of the abutting workpiece Z.

Such a shaping means allows the bucket B to move in the transport direction when the cross-sectional state of the workpiece Z transferred to the bucket B is disturbed during the transfer and is significantly different from a predetermined shape. The upper part of the work Z is leveled by the pressing plate 5 which is in contact with the upper part of the work Z, so that the cross-sectional state of the work Z is approximated to a predetermined shape. The shaping means thus formed is suitably used mainly for medium and small-diameter long materials A, for example, those having a diameter of about 200 mm or less.

In FIG. 3, a rod 6 constituting the delivery means is provided.

Next, the operation of the transfer apparatus described above will be described with reference to the accompanying drawings. In FIG. 1, a long material A is separately placed and conveyed on a partition member 11 of a chain conveyor 8. The long material A is delivered by sliding on the delivery plate 3 at the end of the chain conveyor 8. When the delivery plate 3 is pivotally displaced to the uppermost position, the long material A falls close to the left end in the drawing of the concave base 1, and when the delivery plate 3 is rotationally displaced below it, the concave base is used. 1 falls to the center or right in the figure. The rotating position is determined according to the diameter or weight of the long material A to be conveyed, and is set so that the crossing state, the damage on the outer peripheral surface, the noise, and the like are minimized.

When the long material A is delivered, the concave base 1 is at the raised position. Further, the rod 4 serving as the mounting means is also at the position where the rod 4 is rotated and displaced, and receives the long material A,
When a predetermined number of the long members A are sent out, the rod 4 is pivotally displaced downward and the received long members A are gently lowered onto the concave base 1 and placed thereon, and a predetermined number of the workpieces Z are transferred. Form. By doing so, it is possible to prevent the long material A from dropping or bouncing obliquely due to dropping at a high drop, thereby preventing the occurrence of an intersecting state and also suppressing the generation of scratches and noise on the outer peripheral surface. doing.

When the long material A is placed on the concave base 1, the concave base 1 is lowered by the operation of the driving device, and the bottom of the concave base 1 is lowered below the bottom of the bucket. Is transferred to the bucket B.

When the length of the long material A is approximately 200 mm or less,
In the case of a small diameter, the workpiece transferred to the bucket B is transported in the arrow direction L while being transported to the bucket B, and sent to the next sizing step (not shown). In many cases, the Z-assembly cross-sectional state does not yet have a predetermined shape due to disturbance during transfer and the like. In such a case, as shown in FIG. 2, the upper portion of the work Z is pressed against the upper portion of the work Z by the pressing plate 5 constituting the shaping means, and a part of the upper portion of the work Z transferred to the bucket B in one direction. It is preferable that the long material A is leveled and the sectional shape of the work Z is approximated to a predetermined shape. The pressing plate 5 is set by switching its position by the switching cylinder 20. Usually, several switching positions can be set according to the diameter of the long material A and the shape of the work.

When the long material A has a large diameter of about 200 mm or more and is tied or wrapped one by one, a delivery means is used as shown in FIG. The distal end of the rod 6 constituting the delivery means is rotated and displaced to the vicinity of the end of the chain conveyor 8 to receive one large-diameter long material A sent out by the chain conveyor 8 and to operate the drive cylinder 7. As a result, the distal end portion of the rod 6 is pivotally displaced downward, and the long material A received by the rod 6 is gently descended and placed on the concave base 1. The rod 6 on which the long material A is placed on the concave base 1 is rotated as it is to the horizontal position, and the long material A on the concave base 1 is transferred to the bucket B below the bottom surface of the bucket B. Do not interfere with By using the delivery means in this way, it is possible to prevent the outer peripheral surface from being damaged or noise generated when the heavy material A having a large diameter falls from the chain conveyor 8 to the concave base 1.

The driving device used in the present invention is not particularly limited, and an air cylinder, a hydraulic cylinder, an electric motor and the like can be used.

Examples of the long material A that can be processed by the long material transfer device according to the present invention include round steel bars, rolled steel bars, synthetic resin bars, synthetic resin pipes, metal tubes, and wood. As the caliber, a long material A having a diameter of about 10 to 400 mm and a length of about 4 to 5 m can be processed, but a diameter of 10 to 40 m.
It is particularly suitable for those having flexibility with a small diameter of about m.
