[0002]

2. Description of the Related Art Generally, in an automatic hexagon socket set screw feeder for supplying hexagon socket set screws to an operator in an optimum working condition, first, a hopper that stores a large amount of hexagon socket set screws is used. Each set screw with a hexagonal hole is extracted so as to be in an appropriate state, sent out to the next process, and further distributed to the workers.

The device for extracting the hexagon socket set screw must efficiently and efficiently extract the hexagon socket set screw.

[0004]

However, in order to continuously and efficiently extract one hexagon socket set screw from a hopper in which a large number of hexagon socket set screws are stored randomly, in an appropriate state. With a high probability, a large amount of hexagon socket set screws must be extracted from the hopper with a very high probability, and the improperly inserted hexagon socket set screws must be promptly removed.

In order to meet such demands, the device has a complicated structure, and accordingly, the device tends to be expensive.

[0006]

Therefore, as a result of earnest researches to solve the above problems, the present inventors

Furthermore, the inclined bottom surface 1a of the bottom portion 1 of the storage tank A ₁
An upper stirrer 6 is provided in the upper part, and the storage tank A
_The hexagon socket set screws S, S, ... Released in ₁ are discharged by the upper stirring body 6 to the low position of the inclined bottom surface 1a of the storage tank A ₁ .

Next, the transfer device C will be described with reference to FIG.
As shown in FIG. 7, the hexagon socket set screws S, S, ... Which are mainly composed of the transfer path C ₁ and the belt mechanism C ₂ and are carried from the rotary transfer device B pass through the transfer device C. However, it is transferred to the take-out device D described later.

In the transfer path C ₁ of the transfer device C, the hexagon socket set screws S, S, ... Are in proper condition, that is, the hexagon socket set screws S, S ,. All of the hexagon socket set screws S, S, ... Entering upward and entering the transfer path C ₁ are further moved in a predetermined direction by the belt rotation of the belt mechanism C ₂ .

First, the transfer path C ₁ is specifically shown in FIG.
As shown in FIG. 5, a transfer path surface 13 having a substantially U-shaped cross section is formed in contact with the upper and lower and outer peripheral side surfaces of the hexagon socket set screw S, and the transfer path surface 13 has a width direction (direction orthogonal to the path transfer direction). ) One side is an open side 13a opened to the outside, and the other is a wall side surface 13b. The belt surface of the belt mechanism C ₂ is arranged on the open side 13a, and the hexagon socket set screw S is sandwiched on the transfer path surface 13 between the belt surface on the open side 13a and the wall side surface 13b with an appropriate pressure. The hexagon socket set screw S is transferred in the transfer direction by the rotation of the belt.

Next, the belt mechanism C ₂ is used for the transfer belt 1.
A part of 6 is arranged so as to face the open side 13a of the transfer road surface 13, and a start end guide pulley 17 and an end guide pulley 18 are provided at both ends of the transfer road surface 13 in the road surface direction. Further, in addition to the above pulleys, a drive pulley 19 and a tension pulley 20 are provided (see FIG. 13).

The belt mechanism C ₂ includes the transfer road surface 13
Is always fixed at the proper position with respect to the open side 13a of
Alternatively, if necessary, the belt mechanism C ₂ is used to transfer the road surface 13
There is also an example in which the belt mechanism C ₂ is detachable from the transporting road surface 13. In particular, an example in which the belt mechanism C ₂ is detachable from the transfer road surface 13 will be described. The pulley 18, the tension pulley 20, etc. move and move away from the transfer road surface 13,
In response to this, the transfer belt 16 is detached from the transfer road surface 13.

Specifically, the start end guide pulley 17, the end guide pulley 18, and the tension pulley 20 are properly arranged on the free board 21.
Is connected to the main body base 23 by the swing base plate 22, and the free base plate 21 can be separated from the main body base 23 by the swinging action of the swing base plate 22. Further, the tensioning pulley 20 applies appropriate tension to the transfer belt 16 by means of an elastic body such as a coil spring. By allowing the belt mechanism C ₂ to be appropriately separated from the transfer device C as described above, the transfer road surface 13 can be easily inspected, and the transfer belt 16 can be replaced very easily.

The take-out device D has a structure capable of accommodating one hexagon socket set screw S in the take-out accommodating portion formed in the take-out slide body 24, and is slid by a sliding drive source 26 such as a solenoid or a motor. You can take action.

When the delivered hexagon socket set screws S, S, ... Are stopped at the same time and the take-out slide body 24 slides, and the take-out accommodating portion reaches the hexagon socket set screws S, S ,. The hexagon socket set screws S are housed one by one in the take-out accommodating portion, and the take-out slide bodies 24 slide again in the opposite direction to supply the hexagon socket set screws S to the operator's hand. You can

First, a large amount of hexagon socket set screws S, S, ... Are put in the hopper A, and the hexagon socket set screws S, S ,.
Is sent (see FIG. 10). In the supply storage tank 7, the transfer holes 8a, 8 of the rotating body 8 of the rotary transfer device B are provided.
The hexagon socket set screw S, S, ... enters into a, ..., and the hexagon socket set screw S that has entered the delivery hole 8a in the proper state proceeds directly to the next step and is in an improper state. Then, the hexagon socket set screw S that has entered the delivery hole 8a is discharged from the rotating body 8 near the uppermost portion of the rotating body 8 and returned to the storage tank A ₁ through the return opening.

The hexagon socket set screw S properly inserted into the delivery hole 8a of the rotating body 8 is sent out to the transfer device C as shown in FIG. More specifically, FIG. 14 and FIG.
As shown in FIG. 5 (a), the sliding pin 9 is sent out from the delivery hole 8a of the rotating body 8 while being inserted into the hexagonal hole Sh, and then, as shown in FIG. When the delivery hole 8a of 8 reaches the lowermost portion, the hexagon socket set screw S intersects with the transfer belt 16. At this time, the sliding pin 9 is still inserted in the hexagonal hole Sh of the hexagon socket set screw S (see FIG. 16). Further, the rotating body 8 rotates and the sliding pin 1 comes out of the hexagonal hole Sh of the hexagon socket set screw S,
This time, as shown in FIG. 15C, it is transferred to the next step only by the transfer belt 16 (see FIG. 16).

When the end of the transfer device C is reached, the hexagon socket set screws S are inserted one by one into the take-out accommodating portions 24a of the take-out slide bodies 24 of the take-out device D, and the take-out slide bodies 2 are taken.
By the reciprocating sliding movement of No. 4, the hexagon socket set screw S is efficiently delivered to the operator's hand.

[0036]

According to the invention of claim 1, firstly, the hexagon socket set screw S in an improper state can be surely and quickly returned to the hopper A, and secondly, the hexagon socket set screw S is provided. There are various effects such as relatively easy entry into the delivery hole 8a.

To explain the above effect in detail, the outer peripheral surface of the rotating body is formed in an inclined shape so that the side surface having a small diameter faces the hopper side, and the discharged set screw with the hole is discharged to the hopper side. Since the return opening for receiving is formed, the hexagon socket set screw S that has entered the delivery hole 8a inappropriately is in an inappropriate state from the delivery hole 8a due to the discharging work of the rotary delivery device B. When the hexagon socket set screw S is pushed out, the hexagon socket set screw S can be returned to the storage place of the hexagon socket set screws S, S, ...

Further, since the outer peripheral surface of the rotating body 8 is formed in an inclined shape, the hexagon socket set screw S that has entered from the direction of the rotation axis of the rotating body 8 is relatively easy to enter the delivery hole 8a. .

According to the second aspect of the invention, the hexagon socket set screw S is used.
Is relatively easy to enter the delivery hole 8a.
