Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention is intended for aligning a needle member aligning device, particularly a needle member used for a fuel injection valve or the like, on a aligning chute for assembly after grinding. The present invention relates to a needle member aligning device used.

[Prior Art] Conventionally, as such a needle member alignment device, a device as shown in FIG. 6 has been known.

Explaining this with reference to the drawings, 1 is a discharge chute such as a grinder, 2 is a guide provided with standing walls 2A on both sides, an inclined passage 2B is provided in the center, and 3 is moved up and down along the guide 2, A pusher having an inclined surface 3A on the upper surface. The pusher 3 is driven in the vertical direction by an air cylinder 4. Reference numeral 5 is an alignment chute, and two guide bars 5A and 5B arranged at a predetermined interval are provided in parallel with a predetermined inclination.

Then, the needle member N discharged from the discharge chute 1 first slides down along the inclined passage 2B of the guide 2 and is placed on the inclined surface 3A of the pusher 3. Then, the pusher 3 is driven by the air cylinder 4 to move upward, slide the needle member N along the inclination of the inclined surface 3A, drop it on the alignment chute 5, and discharge it. The discharged needle member N is suspended by the guide bars 5A and 5B and slides down along the slope to be aligned.

[Problems to be Solved by the Invention] However, in such a conventional needle member aligning device, the needle member N is caught in the middle of the pusher 3 even though the inclined surface 3A is provided on the upper surface of the pusher 3. There was a problem that it may fall into 5 and may not be discharged. This is because the cutting oil or the like remains attached to the needle member N that has been ground, and the adhesive force prevents the oil from falling.

If the needle member N is caught on the aligning chute 5 side and is not discharged, the next needle member N flows from the discharge chute 1 side as the pusher 3 moves downward.
It collides with the stuck needle member N. Then,
There is a risk of scratching the surface of the sheet, which requires strict surface accuracy, and it must be discarded as a defective product.

An object of the present invention is to provide a needle member aligning device that solves the above-mentioned conventional problems, reliably discharges the needle member to the alignment chute, and prevents scratches and the like from occurring.

[Means for Solving Problems] In order to achieve the above object, the present invention guides a needle member discharged from a chute to an inclined surface of a pusher upper surface, and moves along the inclined surface as the pusher moves upward. In the needle member aligning device adapted to be dropped into the aligning chute of the needle member and discharged, the pusher is located on the upper side of the inclined surface in the inclination direction and on the lower side of the inclination direction. Divided into two with the second pusher,
When the needle members guided on the inclined surfaces of the first and second pushers are dropped into the alignment chute and discharged, the first and second pushers are simultaneously moved up to a predetermined position, and then the first and second pushers are further moved. It is characterized in that a driving means for moving only one pusher upward by a predetermined amount is provided.

[Operation] According to the present invention, the needle member discharged from the chute is guided and placed on the inclined surface of the pusher upper surface. Then, the needle member is lifted upward with the upward movement of the pusher. At this time, the pusher is divided into two parts in the direction of dropping into the alignment chute and operates in two stages, so that after one division part first stops moving upward, the other division parts continue to move upward.

Then, the inclination of the needle member placed on the inclined surface becomes larger than the inclination of the inclined surface due to the step of the dividing portion, so that the needle member surely slides down to the alignment chute side and is discharged.

Therefore, the occurrence of scratches due to the collision of the needle members can be prevented.

[Embodiment] An embodiment of the present invention will be described below with reference to the accompanying drawings.

1 to 5 show one embodiment of the present invention. In the figure, 11 is a base, 12 is a lower support block fixed to this base, 13 is a guide fixedly supported by the lower support block via a mounting plate 14, and standing walls 13A are provided on both upper sides.
And has an inclined passage 13B in the center.

Reference numeral 15 denotes an exhaust chute arranged to have an inclination that matches the inclination of the inclined passage 13B, and in the present embodiment, an exhaust chute from a grinder that grinds a needle used for a fuel injection valve. is there.

Reference numerals 16 and 17 denote first and second pushers that move up and down while being guided by the guide 13. The first pusher 16 and the second pusher 17 are slidably guided by a slider 16A, and a piston of the air cylinder 18 is provided. Drive arm fixed to 19
It is driven vertically by 20.

The first pusher 16 is directly fixed to the drive arm 20, whereas the spring 17A is interposed between the second pusher 17 and the drive arm 20. First pusher 16 and second pusher 17
Slanted surfaces 16B and 17B are formed on the upper surface of each of the slanted surfaces 16B and 17B, respectively. The direction is such that a groove is formed. The lowermost point of the V-shaped groove is formed to be slightly deviated from the center, and the inclination on one side of the V-shaped groove is described later.
It is almost the same as the slope of 23.

Further, a step portion 17C is provided at the lower end portion of the second pusher 17, and the step portion 17C abuts on the step portion 13C provided on the guide 13, whereby the upward movement of the second pusher 17 is restricted.

Reference numeral 21 is an upper support block fixed to the guide 13 and supports the above-mentioned air cylinder 18 via brackets 22A and 22B.

23A and 23B are resin side plates arranged in parallel, respectively, and guide bars 23C and 23D are embedded in the both in an inclined state to form an alignment chute 23. Then, the lower end side of the alignment chute 23 is connected to the next step, for example, the assembling step.

The operation of this embodiment having the above structure will be described below.

First, a needle that has been ground (diameter 5.5 mm, length 3
0 mm) is discharged from the discharge chute 15 onto the inclined passage 13B of the guide 13. Then, the needle falls while rolling or sliding, and is placed on the inclined surfaces 16B and 17B of the first and second pushers in the lowered position.

At this time, the thicknesses of the first pusher 16 and the second pusher 17 are set to about 12 mm and 8 mm, respectively, and when the needle slides down in a state where the axial direction of the needle and the inclination direction of the inclined passage 13B match. A part of the needle is held in the state of being slightly protruded from the first pusher 16 and the second pusher 17.

Then, the air cylinder 18 operates and the drive arm 20 causes the first pusher 16 and the second pusher 17 to start moving upward from the solid line state shown in FIG.

After a predetermined distance from the start of upward movement, the step portion 17C of the second pusher 17 abuts the step portion 13C of the guide 13 and the movement of the second pusher 17 stops. At this time, the inclined surface 17B of the second pusher 17 and the side plate 23A of the alignment chute 23 are in a state of being coincident with each other (shown by a chain line in FIG.

In a normal case, in such a state, the needle rolls along the inclined surface 17B and falls toward the alignment chute 23 side and is discharged.

However, from the above state, the air cylinder 18 continues to operate and moves the drive arm 20 upward. Then, the second pusher 17
In the stopped state, a so-called two-step operation is performed in which the spring 17A is compressed and only the first pusher 16 is moved upward as shown by the alternate long and short dash line in FIG. Then, even if the needle is held in the protruding state as described above, the needle is raised by the step at the upper ends of the first pusher 16 and the second pusher 17, and the influence of the adhesive force due to the grinding oil or the like is almost eliminated. Therefore, it is easily dropped into the alignment chute 23.

The needle dropped into the alignment chute 23 is a guide bar 23.
C and 23D allow the neck to be held and slid down and aligned along the slope while being suspended.

[Effects of the Invention] As is apparent from the above description, according to the present invention, no matter how the needle member is discharged,
It is possible to reliably discharge to the alignment chute, and prevent scratches and the like due to being caught.

That is, the pusher is divided into two, a first pusher and a second pusher located on the upper side and the lower side of the inclined surface of the pusher upper surface, and when dropping the needle member guided on them into the alignment chute, first of all, , The second pusher is simultaneously moved up to a predetermined position, and then a two-step operation is performed in which only the first pusher is further moved up by a predetermined amount, so that the first pusher moves backward in the needle member feeding direction. Can be partially lifted higher to ensure that the needle member slides down onto the alignment chute. Therefore, even if cutting oil or the like having an adhesive force adheres to the needle member, the needle member can be reliably dropped and aligned on the alignment chute.
