The present invention for achieving the above object is, a plurality is arranged in parallel on the upper side of the frame and each of the rotating shaft is connected to each other by a transmission motor and the drive motor is connected to the drive motor; A plurality of cams are installed in the space between the frame and the screw and interlocked with the driving motor to generate one forward and backward movement every one rotation of the screw. It relates to a conveying device using a screw characterized in that.

The conveying apparatus using the screw according to the present invention may be configured to be capable of conveying not only a rod-shaped material or a hollow pipe of circular section, but also a material such as a rectangular section according to the shape of the screw section.

Hereinafter, with reference to the accompanying drawings for the transfer device using a screw according to the present invention will be described in more detail. Figure 3 is a plan view showing a schematic configuration of the transfer device using a screw configured by the present invention and Figure 4 is a cross-sectional view taken along the line AA (A-A) in FIG.

As shown in Figure 3 to 4, the transfer device using a screw according to the present invention is composed of a drive motor 100, a screw 200, a cam mechanism 300 and the stopper 400.

Preferably, the operation of the screw 200 and the cam mechanism 300 may be interlocked with one driving motor 100 so as to be accurately and simultaneously operated with each other. That is, the pipe conveying apparatus according to the present invention is characterized in that the rotation of the screw and the cam mechanism must be accurately driven in time to supply the materials one by one accurately.

A plurality of screws 200 are installed in parallel on the upper surface of the frame 90 and a cam mechanism 300 is formed below the screws. The screw 200 and the cam mechanism 300 receives power from the drive shaft 110 connected to the drive motor 100. Pulleys 210 are formed on the rotation shafts of the screws 200 so that input and output can be simultaneously performed, and are connected to each other by the belt 220.

In addition, the cam mechanism 300 is composed of a rack gear 310, a pinion gear 320 and a pusher 340 is operated in conjunction with the drive shaft 110.

When the material 70 is continuously supplied from the top of the screw 200, the material is placed in the valley of the screw 200 and moved in one direction while being advanced by the rotation of the screw is made alignment is made to the end of the screw As early as the material falls, the dropped material is placed on the pusher 340 which is advanced. The material 70 placed on the pusher 340 is placed on the upper surface of the frame as the pusher is retracted, and when the pusher is advanced again, the material placed on the frame is discharged and a new material is dropped and positioned on the upper surface of the pusher. By this repetitive process, the material can be continuously supplied.

The overall configuration of the transfer apparatus using the screw according to the present invention has been described above. Hereinafter, a detailed structure and an operation relationship will be described.

5 is an exemplary view showing a preferred embodiment of a transfer apparatus using a screw according to the present invention, and will be described in more detail with reference to FIG. 3 or 4.

As shown in FIG. 5, a material supply part 500 in which the material falls is installed on the upper part of the screw, and a plurality of materials 70 are stacked therein so as to fall at a predetermined time interval.

Preferably, the number of the screw 200 and the number of the pushers 340 may be varied according to the length of the material, and the position thereof may also be adjusted, and the stopper 400 may be adjusted according to the spiral direction of the screw. This can be done by placing the position left or right.

As shown in FIG. 3, one drive motor 100 is installed and power is output from the drive motor to the drive shaft 110. The drive shaft 110 is constrained by a bearing and is rotated by being connected to the drive motor 100 as a belt and a pulley.

And an output pulley 215 is installed on the drive shaft to be connected to the nearest one of the screw 200 as a belt, and one end of the drive shaft 110 is formed with a rotating body 115 for transmitting power to the cam mechanism It is done.

The plurality of screws 200 are installed in parallel, they are connected to each other as a pulley 210 and the belt 220 is made to rotate at the same time, the cam mechanism 300 is a rack gear 310, pinion gear ( 320 and the pusher 340 is connected to the rotating body 115 to generate a repetitive motion. In the cam mechanism 300, the rotational motion of the rotating body 115 is converted into a linear motion in the rack gear 310, and in the pinion gear 320 engaged with the rack gear 310, the rotational motion occurs again, and the pinion gear ( The pusher 340 fastened by the 320 and the connecting rod 330 is linearly moved back and forth.

In FIG. 3, the rack gear 310 is installed in two places and interconnected to operate at the same time. However, the rack gear 310 is not limited thereto. It is preferable to increase the number of screws and rack gears as the length of the material increases. Do.

The connection between the rotating body 115 and the first rack gear 310 to form a structure that is connected to the connecting rod 330 and the bushing (not shown), the connecting rod 330 is coupled to the pinion gear 320 Also connected to the bushing (not shown) so that power can be transmitted smoothly.

When the screw 200 is rotated once, the material is advanced by one pitch. As shown in FIG. 5, one material is continuously supplied to each bone of the screw so that the screw 200 may be rotated once. Each time one material falls on the upper surface of the pusher 340. The pusher also performs one reciprocation movement in accordance with one rotation of the screw, thereby allowing the material to be continuously supplied one by one to the next process. That is, when the pusher 340 moves forward, the material 70 placed on the frame is pushed out, and at this time, one material falls from the screw 200 and is placed on the top of the pusher 340. By retraction the workpiece is placed on the frame top. When the pusher is advanced again, the material is discharged and the same process is repeatedly performed.

And the material conveyed by the rotation of the screw 200 is moved forward or left at the same time in the direction of rotation of the screw so that the material is in contact with the stopper 400 is always supplied to be aligned to a certain position Have characteristics.

On the other hand, the screw 200 is made of a synthetic resin material, such as nylon, unlike the general metal material should be so as not to damage the surface of the material when friction with the material. Of course, the center portion and the rotating shaft of the screw is made of a metal material to form a screw in which the valley and acid is formed of a synthetic resin material on the outside of the center portion.

As described above, the screw and the pusher to be operated correctly are related to the rack gear, the pinion gear teeth and the like connected to the drive shaft, and the description thereof will be omitted as it is known.

The present invention by the configuration as described above has the effect that can be continuously and smoothly transported while preventing the surface damage of the material when transferring the wire or pipe, such as difficult to handle to the processing line.
