Round bar transfer device according to the present invention is a combination of a plurality of attachments to the winding winding (wrapping connector) that is wound around the driving wheel and driven wheels are sequentially supplied one by one through the gripping groove of the attachment hopper It is to be transported in the state maintained.

The combination of the driving wheel, the driven wheel, and the winding power drive may be collectively referred to as a so-called winding connector driving gear, and the present invention according to the form of the winding drive device for sequentially transferring the round bar is shown in FIGS. It can be described by dividing into a round bar transfer device consisting of a chain-type winding transmission device as shown in Figure 3, and a round bar transfer device consisting of a belt-type winding transmission device as shown in FIG. Of course, the technical idea of the present invention is not limited to the two embodiments described below.

1 is a side view showing a round bar transfer apparatus according to the present invention, Figure 2 is a partially enlarged view of Figure 1, Figure 3 is a partially exploded perspective view showing the chain shown in FIG.

1 to 3 shows a round bar transfer device consisting of a chain winding motor. In this case, the driving wheel, the driven wheel, and the winding drive section may be embodied by the sprocket wheels 10 and 11 and the chain 12, respectively.

The sprocket wheels 10 and 11 may be divided into a driving wheel and a driven wheel as a configuration for driving the winding drive, that is, the chain 12. The sprocket wheel 10 to be a driving wheel may be rotated by a motor (not shown). Of course, the sprocket wheel 10 may be driven by a hydraulic motor or a servo motor in order to accurately control the transmission of the chain 12.

On the other hand, the sprocket wheel 11 to be the driven wheel is configured to maintain a constant tension of the chain 12 and to rotate together when driving the drive section, so that at least one or more when the need to adjust the tension in accordance with the situation It is necessary to rotate together with the drive wheels.

The chain 12 is a winding transmission shaft wound around the driving wheel and the driven wheel, and is rotated here by the rotation of the sprocket wheels 10 and 11.

Attachment 13 is a configuration in which a plurality of the array 12 is coupled to the chain 12 at regular intervals, and the round bar 1 is seated in the gripping groove 13a so as to be transported by transmission of the chain 12. Attachment 13 is a separate part divided from the chain 12 may be combined with the chain 12 to form a form that is electrically driven together, as shown in Figure 3 to form a part of the chain 12, together with the transmission It can also be shaped.

3 illustrates a structure in which attachment 13 forms part of the chain and transfers round rods as a preferred example of attachment. Here, the chain 12 includes a pair of link plates 12a and 12b opposed to each other, and the attachment 13 is linked by a pair of link plates 12a and 12b and link pins 2 and 4 so that the chain 12 Will form part of.

On the other hand, the attachment 13 may be formed with a recessed groove (13b) in which the link plate (12a, 12b) is inserted in the lower portion so as to ensure the transmission of the chain (12). Attachment 13 is connected to the link plate (12a, 12b) and the link pins (2, 4) through the recessed groove (13b) can be reliably transferred to the round bar is placed and transported on the top without vibration. 3 schematically shows the fastening by the link pins 2 and 4 between the attachment 13 and the link plates 12a and 12b.

In addition, the attachment 13 is formed in the hopper 14 due to the separation between the attachment and the attachment while the step 12c, 13d is formed on both sides thereof so that the chain 12 passes through the outer circumferential surfaces of the sprocket wheels 10, 11. It can be made to prevent the shaking of the round bar (1). When the stepped portions 13c and 13d are formed, the round bar 1 loaded on the hopper 14 may be naturally guided to the gripping groove 13a of the attachment 13 without being pushed into the spaced space between the attachments.

3 shows a link block 3 having no gripping grooves formed thereon, wherein adjacent steps between the attachment 13 and the link block 3 are alternately formed to prevent collision between the two. It is. The link block 3 has the same structure as the attachment except that the gripping groove is not formed. The link block 3 is configured to transfer the round bar supplied from the hopper one by one at intervals, and is linked by a pair of link plates and mutual link pins. It can be said to be a link plate of a deformed form forming a part of the chain and is functionally different from the attachment (13) for placing and transporting the round bar.

On the other hand, it is preferable that the stepped portions 13c and 13d formed on both sides of the attachment 13 are formed so that the left and right sides alternate with each other. In this case, even one attachment with the same structure is suitable for forming the entire chain by connecting with the link plate, which is preferable in terms of manufacturing cost.

The hopper 14 is a structure which falls one by one in order, and supplies it to the attachment 13 in the state which mounted many round bars. The hopper 14 can be placed in the holding groove 13a of the attachment 13 by rolling down the round bar loaded through the inclined plate 14a as shown in FIGS. 1 and 2.

Hereinafter, describing the operation of the present invention according to the progress of the round bar, the plurality of round bars loaded on the hopper 14 are placed one by one in the gripping groove 13a of the attachment 13 one by one, and then the sprocket wheel 10, The linear movement of the chain 12 by the driving of 11) is continuously carried out while maintaining a constant interval. During the transfer, the round bar will go through various processing steps, such as cutting or heat treatment, and after the processing is completed, the round bar will be separated from the gripping groove 13a of the attachment 13 at the position opposite to the initial starting position.

Of course, Figure 1 shows the present invention in a side view, but the driving wheel and the driven wheel, the winding drive to drive the long rod in the longitudinal direction, the driving wheel and the driven wheel is each made of a pair of sprocket wheels having the same rotation axis, winding The rolling element consists of a drive wheel with a pair of sprocket wheels and a pair of chains wound around the driven wheels, so that the rods can be supported in the longitudinal direction two points through a pair of attachments each arranged and coupled to the pair of chains. There is.

Figure 4 is a side view showing a round bar transfer apparatus according to another embodiment of the present invention.

On the other hand, Figure 4 shows a round bar transfer device made of a belt-type winding motor. In this case, the driving wheel, the driven wheel, and the winding drive section may be embodied by the pulleys 20 and 21 and the belt 22, respectively.

In this embodiment, as in the above-described embodiment, a plurality of round rods may be continuously transferred through an attachment coupled to the belt by driving the belt, which is a winding drive shaft, through a pulley constituting the driving wheel and the driven wheel. In some cases, the belt may be configured as a timing belt to more accurately transmit the rotational driving force of the pulley.
