Description

[Detailed Description of the Invention] The present invention relates to a work interval conversion device for round bars or similar round bar-shaped workpieces, and more specifically relates to a work interval conversion device on a rail that is continuously transferred. This workpiece interval conversion device is designed to convert the workpiece interval to the workpiece conveyance pitch of a direct transfer machine for taking two workpieces, but it can also be applied to other machines.

Next, to explain the details with reference to the drawings, 1 is a fixed inclined rail to which a round bar or a similar round bar-shaped workpiece supplied from a work stocker device (not shown) is transferred, and the tip of this inclined rail 1 is The tip 2a of the switching rail 2 is connected to 1a.

As shown in the figure, the switching rail 2 has a pivoting mechanism that pivots the tip end 2a of the hinge pin 3 upward, that is, a swinging lever 4 attached to the switching rail 2, and a swinging lever 4 attached to the switching rail 2. A cylinder 5 is attached that pulls 4 upward.

Further, near the tip 2a of the switching rail 2, works Wl, W2, . W3. W
4... A locking member 6 for locking Wn is provided to protrude from the upper surface of the rail of the switching rail 2.

Workpieces Wl, W2 . W3. Among W4,
Work W3. W4 is operated by a shutter mechanism, that is, a partition plate 7 located above the above-mentioned inclined rail 1, and a cylinder 8 that moves the partition plate 7 forward and backward in the vertical direction. It is designed to separate the second of W3 and W4.

A connecting portion 1a between the above-mentioned inclined rail 1 and switching rail 2,
2a and the rear end 2b on the side of the switching rail 2, workpiece receivers 9 and 10 are arranged, respectively. It is attached to the transport bar 11 on the machine side.

Note that the above-mentioned conveyance bar 11 is moved in the direction of the illustrated arrow from the position indicated by the solid line by a conveyance cylinder (not shown).

Since the present invention has the above-mentioned configuration, the partition plate 7 of the shutter mechanism allows the works Wl, W2, which are on the inclined rail 1 and the switching rail 2. W3. W3 of W4. With W4 partitioned as shown in the figure, when the switching rail 2 is rotated from the solid line position to the chain line position by the rotating mechanism (consisting of the swing lever 4 and cylinder 5), the workpiece W1 on the switching rail 2 is rotated. is detached from the locking member 6 near the rotation end of the switching rail 2 and enters the W1 state.

Therefore, the workpiece W1 is transferred on the switching rail 2, and the workpiece receiver on the -blade side is supplied onto the pick-up member 10.

Further, as described above, when the switching rail 2 rotates from the position shown by the solid line to the position shown by the chain line, the workpiece W2 is moved through the gap H formed between the tip 1a of the inclined rail 1 and the tip 2a of the switching rail 2. The other workpiece receiver falls and is supplied onto the pick-up member 9.

When the above-mentioned works Wl and W2 are supplied onto both the workpiece receivers 9 and 10, the switching rail 2 is returned to its original position, that is, the position indicated by the solid line, by the rotating mechanism.

When the switching rail 2 returns to its original position, the shutter mechanism rises and the workpiece W3. Release the W4 partition.

As a result, work W3. W4 is transferred on the inclined rail 1, and the leading W3 comes into contact with the locking member 6, and successive works (not shown) after the work W4 are stopped.

When the workpiece W3 comes into contact with the locking member 6, the partition plate 7 of the shutter mechanism descends again to the position shown by the solid line, and the workpiece W3.
Separates the work after W4.

Further, during the above-described operation, the workpieces W1 and W2 supplied onto the workpiece receiving members 9 and 10 are transferred by the conveyance bar 11 in the direction of the arrow shown in the figure, and then transferred to the processing station.

When the transfer of the workpieces Wl and W2 between the processing stations is completed, the transport bar 11 returns to its original position, that is, the position indicated by the solid line, and waits.

Note that the subsequent operations repeat the above-described operations in sequence.

As described above, according to the present invention, the workpiece spacing of round bars or similar round bar-like workpieces that are continuously transferred in close contact with each other on the rail can be changed to any desired workpiece spacing. This effect can be easily obtained by simply changing the length of the switching rail.
