Abstract

PURPOSE:To make stable continuous feed for T nuts attainable, by promoting the alignment of the set T nuts with the presence of a side member having ample clearance capable of receiving a washer part of the T nut 1, in case of a parts feeder which is suitable for feeding each of these plural T nuts consisting of a tubular part and the washer part. CONSTITUTION:Among lots of T nuts housed inside a bowl in case of a vibrating parts feeder, those coming into a state of being regularly erected upright as turning its washer part 3 down are allowed to pass through a gate part in the front stage, then arriving at a first aligning range, each sense of them is corrected to an almost constant direction. Next, these T nuts 1 arrive at a second aligning range 16 in regular sequence, and when the set T nut 1 are moved forward in a state that each of their washer parts 3 is put in a clearance formed between a side member 26 and a floor surface 17, they pass through a transfer passage 25 whose width size is prescribed by the side member 26 and a side edge 27. On the other hand, those T nuts 1 to be transferred in the state other than that come off the side edge 27 and being dropped down, and after all, these T nuts 1 come to be aligned accurately at the aligning range 16 in consequence.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a parts feeder that moves parts by vibration, and particularly to a parts feeder that moves parts by vibration, and in particular, a part feeder that moves parts by vibration.
It relates to a parts feeder that continuously feeds nuts into a predetermined shoe mill.

Background of the invention FIG. 1 is a perspective view showing an example of the nut.

As shown, the nut 1 has a cylindrical part 2 and a washer part 3.
It consists of Although a thread will eventually be formed on the inner circumferential surface 4 of the cylindrical portion 2, the illustrated T-nut 1 has not yet been threaded. A portion of the washer portion 3 is cut and raised to form two pairs of parallel winds 5°5 and 6,6.

These claws 5 and 6 work to penetrate into the wood when the T-nut 1 is attached to the wood, for example, to prohibit rotation of the T-narrow 1-1, and to prevent the T-nut 1 from being pulled out and falling from the wood. .

The illustrated T-nut 1 is then threaded on the inner circumferential surface of its cylindrical portion using, for example, a tapping machine.

Here, if a large number of T-nuts 1 are to be machined continuously, the T-nuts 1 must be fed into the tapping machine while being aligned in a fixed direction due to the chip size of the tapping machine, for example. (You have to play.

OBJECTS OF THE INVENTION Therefore, a main object of the present invention is to provide a parts feeder that can continuously feed a plurality of T-nuts with their directions aligned into a predetermined chute leading to, for example, a tapping machine. There are four things.

4M Structure and Effects of the Invention In the parts feeder according to the present invention, the width of the moving passage connected to a predetermined chute is such that the width of the moving passage connected to a predetermined chute is equal to defined by the cut-off lateral line. Further, the side member is placed away from the floor surface so as to form a gap in which the washer portion of the nut can be received. The width of the moving path connected to the chute) J method is selected so as to add iH to the following conditions. That is, the first condition is that when the T-nut moves with its washer part placed in the gap formed between the side member and the floor surface, it can pass through the movement passage. , the second condition is that when the T-nut moves in any other state, it comes off the side edge and falls.

As described above, according to the present invention, (1) the nut can reach a predetermined chute when moving with its washer in surface contact with the floor; When the washer falls down and moves in a state where the washer part is separated from the floor surface, it falls from the moving path before reaching a predetermined chute. 1=The plurality of nuts fed into a predetermined chute are always aligned so that their washers are in surface contact with the floor surface.

The present invention has a particularly rapid effect on nail problems and nuts 1, as shown in FIG. That is, in the case of the T Naratoco shown in FIG. Each army (the area yi, 7 or 8 sandwiched by the nails 5.5 or 6.6) cannot enter the gap formed between the side member and the floor. Therefore, T -1 -tt-14j
, 2 pairs) parallel type 5.5i13 and 6,6 are sent into a predetermined chute in a state in which they are lined up one after the other.

An embodiment of the present invention will be described below with reference to the drawings.

DESCRIPTION OF EMBODIMENTS FIG. 2 is a perspective view of an embodiment according to the present invention seen from above. In the figure, a number of T-nuts (not shown) placed in a circular bowl 9 are shown. , and is continuously fed into a predetermined shoe 1-10 along the path shown by the arrow by the vibration operation.In other words, the bottom surface of the circular bowl 9 is shaped like a mountain with the medium-heated part as the peak. Moreover, a spiral slope 11 that gradually rises is formed on the inner surface. Therefore, the nut located inside the bowl 9 first moves along the arrow a near the inner surface of the bowl 9. : tC moves, and U5 moves along the spiral slope 11 along the arrows c, d, and e. Only the T nut that has been moving while maintaining the predetermined state of C1 is the bowl 9. (indicated by arrow f),

returned inside. The T-nuts that have passed through the gate section 12 are then selected in the stepped path area 13 so that only those in a constant state remain, and then branched into two directions in the branching area 14 (as indicated by arrows g and 11). figure). Furthermore, [-Puttsu is
The materials are aligned in a certain direction by passing through the first alignment area 15 and the second alignment area 1G, and are continuously fed into a predetermined chute 10 connected to, for example, a tapping machine.

Below, the gate part 12, the stepped word area 73, the branch area 14,
The first alignment area 15 and the second alignment area 16 will be explained in order.

First, prior to explaining the gate portion 12, the dimensional relationship of the T-nut 1 placed in the bowl 9 of the parts feeder shown in FIG. 2 will be explained using FIG. 3 J5 and ¥34. 3 and 4 are front views of the T-nut 1 placed in the bowl 9 of the tabbert feeder shown in FIG. 2, and FIG. 3 shows the T-nut 1 in a fallen state; v84
The figure shows the T-nut 1 standing with its dispensing part 3 in surface contact with the floor 17. In FIG. 3, 'IJ 117, indicated by A, is the height from the floor surface 17 when the T-narrow 1-1 is lying down in the J: prone position shown in the figure.

On the other hand, the j method of l-1 shown in FIG. 4 is a test from the floor surface 17 when the T-nut 1 is standing with its washer 3 in surface contact with the floor surface 17. And, it is more convenient than the degree [-Nara 1 to 1, where the dimension A is 1 and the dimension A is 1] used in this embodiment.

FIG. 5 is a perspective view of the game I part 12 viewed from above inside the bowl 9. As shown in the diagram, ■ Natsu 1 is S 1.
- moves over the top 11 and reaches the gate section 12. S[l
-111, a gate plate 18 is arranged at a predetermined distance B from the floor in1. Here, "law B
is smaller than the dimensions in FIG. 3, but larger than the dimension 1 in FIG. Therefore, ■ Natsu 1
is when the washer 3 is brought into surface contact with the floor 17 as shown in FIG. 4, or when the state is rotated 180 degrees as shown in FIG. It is possible to pass through the gate plate 18 only by moving with the top surface in contact with the floor surface 17.

However, when the nut 1 is tilted down as shown in FIG. 3, it cannot pass through the gate plate 18. That is, in FIG. 5, T oak]-1a, 1b and 1
d can pass through the gate plate 18, but the T-nut 1C cannot. The T-nut 1C that cannot pass advances further forward along the gate plate 18, and then returns along the inclined surface 19 into the bowl.

The T-nut 1 that has passed through the gate portion 12 passes through the step distance region 13.
leading to. FIG. 6 shows T-narrows 1 to 1 on the stepped road area 13.
1 is a diagram illustrating FIG. Referring to FIG. 6 and FIG. 2, in the step distance region 13, the floor surface 17 thereof is an inclined surface, and a step 20 is further provided on the way from below to below. Therefore, ■nut 1, as shown in FIG.
While the washer 3 is in surface contact with the floor 17, the inclined surface 1
7, it will stay on the step 20, but when the top surface of the cylindrical part 2 comes into contact with the floor surface 17 at f44, it will come into contact with the step 20. J, C loses balance and falls further downwards. This fallen T-necklace 1- is returned into the bowl 9 again. In this way, only the T-nut in the lζ state with the washer 3 in surface contact with the floor is fed into the next branch area 14.

FIG. 7 shows the branch area 14, the first alignment area 15, and the second alignment area 15.
The alignment region 16 is shown enlarged in 1=Figure.

Referring to FIG. 7 and FIG. 2, the branch region 14 is formed into a Uk shape by abutting two inclined surfaces 21J3 and 22 in a mountain shape. Then, it is sent from the step distance area 13.
The C-1' nut 1 has two inclined surfaces 21Jj and a groove 2.
2, that is, on the ridgeline 23. Ridge line 2
Some of the backs of the T-nuts 1 dropped onto the T-nuts 3 move toward the inclined surface 21, while others move toward the inclined surface 22. In other words, the plurality of T-nuts 1 are branched in two directions in this branching region 14. Each branched direction is followed by a first alignment area 15 and a second alignment area 16, but in the following, for convenience, the position iFI l is shown on the right.
The first alignment area 15 and second alignment area 16 will be explained. It goes without saying that the first position on the left side
A similar +M rule is also applied to the alignment area and the second alignment area.

Exiting the branch area 14 - ``Natsu 1 is in the first alignment area 1 or 1.''
5. FIG. 8 shows that the first alignment area 15 is
FIG. FIG. 9 is a plan view showing the first alignment region 15 together with the T-nut. As shown in the figure, in the first alignment area 15, an alignment plate 24 is arranged parallel to the floor surface 17 and spaced apart from the floor surface 17 by a predetermined distance. The distance between the alignment plate 24 and the floor surface 17 is made large enough to accommodate the washer portion 3 of the T-nut 1. Also,
As shown in FIG. 9, one end of the alignment plate 24 has a curved shape that gradually narrows the passage width in this area. Therefore, the T Naratoko sent to the first alignment area [15] first collides with the curved part of the alignment plate 24, and moves forward while rotating along this curved part. here,
As mentioned above, in the washer part 3 of the nut 1, the regions 7 and 8 sandwiched by the two pairs of parallel winds 5.5 and 6.6 are formed between the alignment plate 24 and the floor surface 17. I can't get into the gap. On the other hand, other areas can enter the gap. Therefore, if the T-nut 1-1 moves forward while contacting the alignment plate 24, many T-nuts 1 will move a part of each washer 3 between the alignment plate 24 and the floor surface 17.
By inserting them into the gap formed between them, they are aligned in a certain direction. That is, in Figure 9, J
Like the T-nut 1e with the third gear, it moves forward with each parallel wind 5, i15 and 6 aligned back and forth. However, the T-nut 1 sent into the first alignment area 15
Not all of them are reliably aligned. There, the nuts 1 in the second alignment area 16 of order C1 are reliably aligned in a constant direction.

Figure 1 () is a cross-sectional view showing the second alignment area 16 with the T-nut 1, and (a) is a cross-sectional view when the T-nut 1 passes through the T-nut 1 with its parallel winds 5 and 6 aligned back and forth. (b) is a diagram when the T-nut 1 is about to pass in a state other than (a>).

FIG. 11 is a plan view showing the second alignment region 16 together with the T-nut 1. As shown in FIG. Predetermined chutes 10 are continuous after the second alignment area 16.

The T-nut movement passage 25 of the second alignment area 16 has a width extending along the passage 25.
, 126 and a truncated side edge 27 along the passageway 25. Although the side member 26 takes the form of a wall in the figure, it is not limited to such a form, and may be a rod-shaped member extending along the moving path 25, for example. As shown in FIG. 10, the side member 26 is placed away from the floor surface so as to form a gap large enough to receive the washer 3 of the nut 1. As shown in FIG. Furthermore, the width dimension of the moving passage 25 is selected so as to satisfy one of the following two conditions. As shown in FIG. 10(a'), the conditions for the first degree are: (1) The nut 1 places its washer part 3 into the gap formed between the side member 26 and the floor surface. This means that it is possible to pass through the movement path 25 when moving in this state. The second condition is that, as shown in FIG. 10(b), when the nut 1 moves in any other state, it comes off the side edge 27 and falls down. The fallen 1-nuts 1 are returned to the bowl 9 of the parts feeder again.Thus, the 1-nuts 1 fed into the second alignment area 16 are transferred to the 1-nuts 1 shown in FIG. Pass through this area with two pairs of parallel winds 5 and 6 aligned one behind the other, and move to the next predetermined chute 1.
Continuously fed into 0.

', 7 ilJ, Example C described above used a nail (-11-Nara 1~) as an example of a T-nut. However, the 12th
It is also possible to use a T-nut that does not have an inverted claw as shown in the figure.
The object of the present invention is to provide a parts feeder that can continuously feed parts f'' into a predetermined space with their 1) directions aligned. Taking the parts feeder shown in FIG. 2 as an example, the elements that should be essential for this purpose are only the second alignment area 6, the gate part 12, the stepped path mjrIil 3, and the first alignment area 7.
5 does not necessarily need to be provided. However, if these are not provided, the movement path 2 of the second alignment area 16
The T toss 5 falling from the T toss 5 will pass through the movement path 25 of the second alignment area 16, and the ratio of T toss 1 to T toss 1 will be very high. In other words, it can be considered that they are provided to increase the proportion of T-nuts 1 that can be obtained.
