Abstract

PURPOSE:To improve the selection precision of obverse and reverse at a feeder for hat type outside form parts or the like, by providing a spiral step portion at a parts container inner periphery portion, and providing a separation guide piece which gradually goes away from a protruding band and at the same time becomes higher, at the end edge of this step portion, and arranging so that the container may be vibrated. CONSTITUTION:A separation guide piece 12 consisting of a portion 13 which is along a side wall plate 9 and a portion 14 which goes away from a protruding band 11, is provided at the end edge of a spiral step portion 2 formed at the inner periphery portion of a container 1. And, this separation guide piece 12 becomes gradually higher from the portion 13, and at the portion 14, arrangement is made so that parts may be able to pass between the portion 14 and an outer plate 16. As a result, ill-postured parts with their nuts 5 located at the lower position are moved with their flanges 4 made to be positioned on the portion 13 of the separation guide piece 12. Accordingly, gradual movement is made along the portion 14, and then separation from the step portion 2 is made, and falling into a receiving box which is not shown in the drawing is made, and recovery is made.

Description

Detailed Description of the Invention (a) Industrial Application Field The present invention relates to a parts feeder for flanged parts. It is a parts feeder for parts such as shapes.

(B) Conventional technology FIG. 2 and JfH [As shown in FIG. Parts feeder 3Kj that supplies parts? When sorting flanged parts 6 consisting of 7 flanges 4 and nuts 5 as shown in FIG. 18, the ones facing upward as shown in FIG. , those facing down must be evacuated from the medium flow step section 2. As a means of this, the width of the medium-flow type step part 2 is narrowed in the middle, and when it is face up, it passes through as it is, but when it is face down, the 7-tenge 4 is pushed by the protruding wall 8 and falls to the left. The width of the stepped portion 2 is set so as to

e→Problem to be solved by the invention If the principle is as shown in FIG.
It is necessary to narrow the width with high precision. If this width is not set with high precision, objects facing up may fall, or vice versa, objects facing down may pass.
As a result, the two sides are sent to the destination. Even if the width is determined with high precision, the surface portion may fall off due to the presence of impurities such as iron scraps.

As mentioned above, the type of control based on the width of the stepped part has poor reliability in sorting, and it is fine if the face-up parts occasionally fall off, but if the face-up parts are sent out, it is normal. Failure to assemble parts will result in defective products.

B) Means for Solving the Problems and Their Effects The present invention is provided to solve the above-mentioned problems.
It is equipped with a separation guide piece that gradually moves away from the protrusion provided on the edge of the spiral step and also becomes higher. Normally, the one with the front side is fed out along the protrusion, but the one with the abnormal back side is sent out along the protrusion. The flange of the one facing upward is lifted up by the separation guide piece and guided to the sideways side of the helical step, thereby causing it to fall off the step.

First, the embodiment shown in FIGS. 1 to 8 will be explained. This spiral stepped portion 2 has a sloped metal whose outer circumferential side is lower, and is provided along the edge of the stepped portion 2. The parts 6 facing upward are fed out along the side wall plate 9, the side Ii surface 10, and the protrusion 11 continuous thereto as shown in FIG.

The strip-shaped separation guide piece 12 has a portion 1 along the side wall plate 9.
As is clear from FIG. 1, this part 14 is in the shape of an arc bent to the right as seen from the plan view. As shown in FIG. 8, the separation guide piece 12 gradually becomes higher from a portion 16, and is at a considerably higher position at a portion 14. In addition, in FIG. 8, the stepped portion 2 is shown in an unslanted state for ease of understanding.

In order to catch the parts that have fallen to the outside of the protrusion 11, the receiving box 15 is welded to the outer surface of the parts container 1, and through holes 1B and 19 are made in the outer plate 16 and inner plate 17. From here, the parts are returned to the 1 yen container.

The entire process of removing the face-down component 6 according to each cross section will be explained. (z) - (2) The second cross section is
As shown in the figure, the flange 4 extends Km from the inner surface of the side wall plate 9, so it continues to move, but in the (3)-(3) cross section, the nut 5 is on the side as shown in Figure 5. In contact with the wall surface 10, the plunger 4 is located above the portion 15 of the separating guide piece 12. (4) - (4) When moving to the cross section, the 7 langes 4 are lifted up near the starting end 1 of the portion 14, as shown in Figure 1g4, and the step 2 is Due to the inclination, the component 6 is pushed toward the portion 14. As the upward movement progresses, the lower surface of the nut 5 is positioned above the protrusion 11 as shown in FIG. 1
The entire guiding effect of 1 is lost, and if it progresses further, the state will fall from the state shown in diagram M6 to fertilization level 15.

The embodiments shown in FIGS. 11 and 12 are of the type that falls directly into the parts container 1 on the opposite side of the above embodiments, and the slope of the stepped portion 2 is in the opposite direction to that of the previous one. The legs and separation guide pieces 12 are also deformed inward. Components having the same functions as those in the previous embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

The embodiment shown in FIGS. 16 to 16 is a case where the spiral stepped portion 2 has no inclination and is in a horizontal state. As mentioned above, it is not possible to use the inclination of the stepped portion 2 to move the parts to one side, so the auxiliary guide piece 20 is placed along the separating guide piece 12, and the one facing down is placed in the →-#4 cross section. (Figure 14) to f
It is gradually lifted away from the protrusion 11 as shown by the two-dot chain line in the cross section of the j@--saki section (FIG. 15).

The one shown in FIG. 15 guides the parts inside the parts container, but the one shown in FIG. 17 is modified so that the parts are guided outside.

(F) Effect According to the present invention, since the flange of an abnormal component facing down is gradually raised by the separation guide piece and guided away from the protrusion, the abnormality can be detected. The part must be removed from the helical step at a distance from the ridge.

Therefore, there is no problem with the highly accurate step width as described above, and it is possible to completely prevent abnormal parts from being sent out by mistake.

In addition, with the type of the present invention, it is possible to easily match the size of the parts when manufacturing the parts feeder by adjusting the size and shape of the separation guide piece.
