Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a work alignment / sorting apparatus.

[0002]

[Prior Art]

 For example, as shown in FIGS. 5 and 6, a workpiece 1 (a valve body of a fuel injection valve) formed of a head portion 1A and a shaft portion 1B having a diameter smaller than that of the head portion 1A is subjected to a total external cutting to obtain a material. When the cutting process is performed from, the chips 2 are spirally wound around the shaft 1B of the work 1 as shown in FIG. 5, or the cylindrical chips 3 are attached to the shaft 1B of the work 1 as shown in FIG. In some cases, it may become attached and may not separate.

As described above, even if the defective work 4 in which the cutting chips 2 and 3 adhere to the work 1 are only a part of the whole work, the work in the subsequent process is hindered, so that the operator can visually check all of them. I was sorting.

[0004]

[Problems to be solved by the device]

 However, such visual selection by the operator is inefficient, and there is a problem that the sorting operation requires a lot of time. Further, in the post-process of cutting, for example, when cleaning is performed, the cut work 1 cannot be directly carried into the cleaning device by using the chute, which makes it difficult to automate the carrying-in. It was

On the other hand, it is possible to automate the loading of the work 1 to which the chips are not attached to the apparatus in the subsequent process by identifying the work 1 by image processing or a combination of a complicated chucking mechanism and a sensor. However, there was a problem that the device structure became complicated and the cost increased.

Therefore, the present invention provides a work alignment / selection device that can efficiently select defective works and that can automatically carry the work into a device arranged in a subsequent process.

[0007]

[Means for Solving the Problems]

 The work supplied by the work aligning / sorting device that sorts defective works with chips adhering to the shaft from among the machined works that have a head and a shaft with a small diameter for this head. A rail made up of a pair of members that locks and suspends the head of the rail is installed in a substantially horizontal plane.On the loading side of the rail, the rails move forward along the rails between the rail members and work or A pusher that sends the defective work to the front through a cushioning member is provided, and a stopper that prevents the movement of the defective work is provided at the upper part of the unloading side of the rail, and the head of the work is located between this stopper and the rail. A gap is formed to allow the movement of the rail, and a discharge pusher that pushes up the defective work on the rail and discharges it is provided between the rail members on the front side of the stopper.

[0008]

[Action]

 When the work is supplied on the rail, if the work does not have chips attached, it is suspended on the rail with the shaft inserted between each member of the rail, and the defective work with chips adhered. In the case of, the chips are placed on the rail as they interfere.

If the work on the rail is free of chips, when the pusher moves forward, the work slides while being hung on the rail and reaches the gap below the stopper. Pusher moves backward. By repeating these movements, the work is front-packed, aligned, pushed out from the unloading side of the rail, and automatically carried into a device arranged in a subsequent process such as a cleaning device. Further, if the defective work is on the rail, the defective work moves to the unloading side of the rail when the pusher moves forward, and is pressed against the stopper via the buffer member. Then, the defective work left on the rail after the pusher makes one stroke is pushed upward by the discharge pusher and discharged from the top of the rail to the outside of the machine.

 An embodiment of the present invention will be described below with reference to the drawings by attaching the same reference numerals to the same parts as those in the conventional structure.

As shown in FIG. 1, a frame 5 of the work alignment / sorting apparatus is provided with a hopper 6 for loading a work on the top thereof. A passage sensor 7 is provided below the hopper 6 to detect passage of the work 1 or the defective work 4. An inclined rail 8 is arranged below the hopper 6, and a rail 9 is supported below the carry-out end of the inclined rail 8 by a lower frame 5A.

A work guide 10 for overturning the work 1 or the defective work 4 sliding down on the inclined rail 8 is supported above the carry-out end of the inclined rail 8 at the lower part of the passage sensor 7.

The rail 9 is configured by arranging a pair of members 9A having a round bar member mounted on the upper part thereof in a horizontal manner with a predetermined distance therebetween. Is larger than the diameter of the head 1A.

On both sides of the rail 9, side guides 11 for guiding the work 1 or the defective work 4 fed from the inclined rail 8 are attached. As shown in FIG. 3, one side upper part of the side guide 11 is formed so as to be inclined outward and downward, and the discharge plate 12 of the defective work 4 is attached thereto as shown in FIGS.

As shown in FIG. 1, a pusher 15 is attached to an extension of the rail 9 on the side frame 5 B of the frame 5. The pusher 15 is composed of a cylinder 13 mounted horizontally on the side frame 5B, a shock absorber 14 interposed by a rod 13A of the cylinder 13, and a pusher body 15A at the tip of the rod 13A.

The pusher body 15 A is arranged between the respective members 9 A of the rail 9, and is moved forward and backward along the rail 9 by the cylinder 13 to carry the work 1 and the defective work 4 on the rail 9 into the rail 9. From the side to the unloading side. A plate 16 is provided on the upper portion of the pusher body 15A so as to project toward the carry-out side of the rail 9.

A stopper 17 is attached to the upper portion of the side guide 11, and a head portion 1A of the work 1 is provided between the lower surface of the stopper 17 and the upper edge of the rail 9 as shown in FIGS. A gap 18 that can be inserted is provided. The stopper 17 is formed with a receiving hole 19 for the plate 16. Here, when the front surface of the pusher body 15A comes into contact with the stopper 17, two work pieces 1 are aligned on the rail 9 below the stopper 17 and the tip of the rail 9 as shown in FIG. To be done.

A discharge pusher 20 is attached to the lower frame 5 A of the frame 5 below the rail 9 near the stopper 17. The discharge pusher 20 has a cylinder 21 attached to the lower portion of the frame 5, and a discharge pusher main body 20A attached to a rod 21A of the cylinder 21. The discharge pusher main body 20A is disposed between the respective members 9A of the rail 9 and moves vertically by the cylinder 21, and reciprocates after the pusher 15 makes one reciprocation.

As shown in FIG. 3, an inclined surface 22 that is aligned with the discharge plate 12 when the discharge pusher main body 20A is raised is formed at the tip of the discharge pusher 20. The discharge pusher main body 20A is provided with a vertical wall portion 23 which is provided on the inclined surface 22 and prevents the defective work 4 from spilling.

According to the apparatus of the above-described embodiment, when the work 1 or the defective work 4 input from the hopper 6 descends along the inclined rail 8, is collapsed by the work guide 10 and is supplied onto the rail 9, The work 1 or the defective work 4 is guided onto the rail 9 by the side guide 11. At this time, the work 1 with no chips attached is hung on the rail 9 with the shaft 1B inserted between the members 9A of the rail 9, but the defective work 4 with chips attached It is placed on the rail 9.

Then, when either one of the work 1 and the defective work 4 is supplied onto the rail 9 in this way, the rod 13A is extended by the cylinder 13 of the pusher 15 which receives the signal from the passage sensor 7, and the pusher is pushed. The main body 15A moves forward.

At this time, when the work 1 supplied on the rail 9 is the work 1 having no chips attached thereto, the work 1 is hung on the rail 9 and pressed by the pusher body 15A, The position P in FIG. 2 is reached. Then, when the pusher main body 15A repeats this operation once again, the next work 1 pushes the work 1 at the P position to move it to the Q position, and by repeating this, the work 1 is sequentially railed. It is sent out from the unloading side of 9.

Therefore, the works 1 sequentially sent out from the carry-out side of the rail 9 are automatically supplied to, for example, the cleaning device arranged in the subsequent process. After the pusher 15 reciprocates to move the work 1, the discharge pusher 20A moves up and down.

On the other hand, when the defective work 4 having the chips attached thereto is supplied onto the rail 9, the defective work 4 pressed by the pusher body 15 A is located near the unloading side of the rail 9. It is held between the stopper 17 and the stopper 17. At this time, the defective work 4 is pressed by the stopper 17 without being damaged by the shock absorbing function of the shock absorber 14, and is prevented from escaping upward by the plate 16 provided on the pusher body 15A. Then, when the discharge pusher 20 is driven next and the discharge pusher main body 20A is lifted by the cylinder 21, the defective work remaining on the rail 9 is supported by the side guide 11 and the vertical wall portion 23 of the discharge pusher main body 20A. However, when the inclined surface 22 of the discharge pusher main body 20A is aligned with the discharge plate 12, the discharge pusher body 20A is discharged from the discharge plate 12 to the outside of the machine. The defective work 4 is efficiently discharged at a low cost, and the work 1 free from chips is automatically selected.
