First, when starting sorting, the slider stopper 3 is fixed at a predetermined position within the section in which the slider 1 moves.

This fixed position is a position where the distance of reciprocating movement of the slider, that is, the stroke, corresponds to an integral multiple of the outer diameter dimension of the elongated object A to be sorted. In addition, the long body receiving rod 6,
6 into the transfer route.

Next, the elongated bodies A... are sent into the transfer path one after another (then, the elongated bodies A... are stopped by the elongated body receiving rods 6, 6, and eventually the slider l The slider 1 is moved to the upstream side of the transfer path by the slider drive means 2 until it comes into contact with the slider stopper 3. At this time, the sorting rods 4, 4 are It has been removed from the transfer route (see Figure 5).

When the slider 1 comes into contact with the slider stopper 3 and stops, the sorting rod drive means 5 is activated, and the sorting rod 4.4 is projected into the transfer path and interposed between the elongated objects A... (
(see Figure 6), here, the long object receiving rods 6, 6 and the sorting rod 4

The receiving rod driving cylinder 7.7 constitutes a receiving rod driving means in the present invention, and is for causing the elongated body receiving rod 6.6 to appear and retract along the transfer path. This receiving rod driving cylinder 7.7 is disposed below near the tip of the above-mentioned Iεε farm 6262, and is configured to be able to swing in the direction along the transfer path with the rod 71.71 on top. It is erected on a base 8. And each Rondore 1.71
The tips of the two are pivotally connected to swing arms 62 and 62, respectively.

Next, the operation of the sorting device described above will be explained with reference to FIGS. 5 to 8.

First, the receiving rod drive cylinder 7.7 is activated, and its round door 1.71 is extended. As a result, the swing arm 62.
62 swings upward and becomes horizontal, and the long body receiving rods 6, 6
are respectively thrust into the transfer route and placed in a standby state.

Subsequently, the drive motor 35 operates to move the slider stopper 3
moves forward or backward and stops when it reaches a predetermined position. This position is a position where the reciprocating distance of the slider I, that is, the stroke, corresponds to an integral multiple of the outer diameter of the elongated body A.

Next, the transport conveyor and the nylon chain conveyor C are operated, and the elongated body A... is transferred to the nylon chain conveyor C.
At the same time, the long body receiving rods 6, 6
Uke is stopped and becomes crowded. Here, whether or not the elongated objects A... are in a dense state above the sorting device can be determined by a sensor (not shown) installed upstream of the transfer route than the sorting device. Movement of A...
This is determined by detecting a stop. Note that even if the long body A... is stopped by the long body receiving rod 6.6, the nylon chain conveyor C has high slipperiness, so it will rub against the long body A... Continue rotating in this position.

While the elongated bodies A are sent in the above manner and are brought into a dense state, the slider drive cylinder 2 is operated and the slider 1 is moved upstream of the transfer path until it comes into contact with the slider stopper 3. Ru. At this time, the sorting column drive cylinder 5
The rod 51 is in an extended state, and both the sorting columns 4, 4 have moved out of the transfer path (see FIG. 5).

If it is determined from the detection result of the sensor that the long objects A are in a crowded state, the rod 51 of the sorting column drive cylinder 5
is retracted and the sorting columns 4, 4 are respectively rotated toward the outside of the slider I, whereby the tip of the sorting column 4.4 is interposed between the elongated body A (Fig. 6). reference). Here, the number of elongated objects A existing between the elongated object receiving rod 6°6 and the sorting columns 4, 4 is determined by the slider stopper 3 being positioned at the position described above. , is the number obtained by dividing the distance between the long object receiving rods 6, 6 and the sorting column 4.4 (equal to the stroke of the slider 1) by the outer diameter dimension of the long object A.

When the sorting columns 4, 4 intervene, the rod 71.71 of the receiving rod drive cylinder 7.7 retracts, and the elongated object receiving rod 6.6 is lowered and removed from the transfer path. At the same time, the slider drive cylinder 2 is activated, and the slider 1 is moved toward the downstream side of the transfer path at a speed greater than the speed of the nylon chain conveyor C. As a result, the long objects A existing between the long object receiving rods 6, 6 and the sorting column 4.4 are discharged from the nylon chain conveyor C while being pushed by the sorting column 4.4. (See Figure 7). At this time, behind the sorting column 4.4, the nylon chain conveyor C continues to feed the next group of elongated bodies A.... When the slider 1 reaches the most downstream side of the transfer path and stops, the long door 1.71 of the receiving rod drive cylinder 7.7 extends, and the elongated object receiving rod 6.6 is raised to move the transfer path. (See Figure 8). This completes the first sorting.

After this, the sorting columns 4, 4 are moved out of the transfer path again, and the slider 1 is moved to the upstream side of the transfer path to enter the next sorting. Thereafter, the same operation as described above is repeated, and a predetermined number of pieces are sorted one after another.

(Effects of the Invention) As explained above, the long object sorting device according to the present invention has the following features:
Since the number of elongated objects is counted by determining the number of elongated objects from the outer diameter dimension of the elongated objects without using conventional sensors, the sorting column can be accurately inserted between the elongated objects.

Therefore, it is possible to sort into a predetermined number of pieces without error. In addition, the position of the slider stopper can be changed arbitrarily, and the stroke of the slider can be made according to the outside diameter of the long object, so it can be used with long objects of any outside diameter. can do.
