In this liquid processing auxiliary device, it is premised that a large number of press parts 10 are inserted through one suspension shaft, and the insertion work is performed by the press parts 10 being thin and small. Therefore, it was done manually, but it was very inefficient. In other words, it has been desired to automate the insertion of each press part 10 into the suspension shaft or the jig rod 40.

Further, when each of the press parts 10 is the above-mentioned leaf valve, it is known that if the assembling method is not made constant, the function as a valve will vary due to individual characteristics. The pressing directions of the pressed parts 10 must be kept constant. This is because each press component 10 is generally slightly deformed in the punching direction.

That is, the press part 10 of this type must be inserted into one jig rod 40 in order to efficiently perform liquid treatment such as chemical polishing. It is necessary to assemble the press parts 10 with a constant punching direction in order to achieve uniform functions. There is a request such as.

[0025]

BEST MODE FOR CARRYING OUT THE INVENTION Next, the invention according to each of the claims constructed as described above will be explained with respect to an assembling apparatus 100 which is an embodiment shown in the drawings.
Substantially includes the invention according to each of the above claims, and therefore, the embedded device 100 will be mainly described below.

In FIG. 1, each of the press parts 10 is shown as 100-.
Press machine 2 for punching at a speed of 500 sheets / minute
00 and a schematic configuration of the embedded device 100 installed on the downstream side. As shown in FIG. 5, the press part 10 punched by the press machine 200 is flat and has an assembling hole 11 substantially at the center.
It is punched from the strip-shaped metal material 12 as shown in FIG. The material 12 that occupied the assembly hole 11 is
The stamped part 10 itself is automatically punched out in the stamping machine 200, and the stamped part 10 itself is stored in the stamping part 12a, which is the stamped hole, in the stamping machine 200.

The material 12 is not limited to the long strip-shaped material as in this embodiment, but may be a strip-shaped material, and in any case, it is continuously fed into the press machine 200. Any form may be used as long as it is one. Of course, the material 12 may have a width capable of taking only one piece as shown in FIG. 3, or a large number of pieces as shown in FIG. 4 (three pieces in the embodiment).
It may have a width that is possible.

The table 20 is made of the material 12 as described above.
Can be conveyed horizontally, and a drop hole 21 for dropping each press part 10 is formed at the front end thereof as shown in FIG. Since the table 20 shown in FIG. 2 conveys the material 12 that can be picked up, only one drop hole 21 is formed at the approximate center of its width, but a large number can be taken. In order to correspond to the material 12, as shown in FIG. 4, it is necessary to form the corresponding number.

The table 20 is shown in FIG.
Alternatively, as shown in FIG.
A cover 22 for wrapping with 2 is formed. In the case where the dropping device 30 to be described later is to perform forced withdrawal at the same time as air blowing, in order to allow the blowing air to be blown directly to each press part 10 together with the insertion of the pulling-off member 13. A ventilation space 22a is formed in the cover 22 as shown in FIGS. Through this ventilation space 22a, the removal member 13 directly presses the upper surface of each press component 10, and the air from the dropping device 30 is directly blown to each press component 10.

Since this built-in device 100 is installed close to the press machine 200 which may generate a large vibration, the vibration is applied to each press part 10 in the middle of conveyance, but the cover 22 presses the press part 10. Parts 10 and materials 1
By covering 2 with each other, it is possible to prevent each pressed part 10 from coming off the processed portion 12a and becoming not parallel to the table 20 due to the applied vibration. Is stable and can be reliably performed without turning the inside out.

In the case of this embodiment, the dropping device 30 blows air to the press part 10 that has come into the drop hole 21 or presses it with the drop-off member 13, as described above. As a result, each pressed part 10 is completely separated from the processed part 12a of the material 12. Therefore, the dropping device 30 may give a vibration instead of pressing by the air or the removing member 13.

Below the drop hole 21, the tip of the jig bar 40 for inserting the dropped press part 10 in the assembly hole 11 must be on standby.
It is the turntable 50 shown in FIG. 1 or 4 that does this. Of course, these turntables 5
Of course, 0 can rotate about its center,
It also allows linear movement in a fixed direction.

The turntable 50 shown in FIG. 1 is configured such that a large number of jig rods 40 can be mounted radially, and the upper ends of these jig rods 40 are successively opposed to one drop hole 21. It was made possible. The turntable 50 shown in FIG. 4 is adapted to use a material 12 capable of taking a plurality (three), and three jig rods 40 are erected in one radial shape. Is. In this case, three drop holes 21 on the table 20 side are also formed, and the ventilation space 22a that opens on each drop hole 21 also has the shape shown in FIG. As a result, the press parts 10 located at the three types of positions of upper, middle, and lower shown by phantom lines in FIG. 4 are individually inserted into the jig rod 40.

The large number of press parts 10 inserted into one jig rod 40 by the above-described assembling device 100 are
The jig rod 40 of the book is used as a suspension shaft, and the jig rod 40 is hung on the liquid processing apparatus as shown in FIGS. The outline and function of this liquid processing apparatus are as follows.

As shown in FIG. 6, this liquid processing auxiliary device is for performing liquid processing such as deburring by chemical polishing and various kinds of cleaning on a press part 10 having an assembling hole 11. A suspension base whose lower end is immersed in a processing liquid tank for the rotation axis, a rotation shaft supported in a substantially horizontal state under the suspension base, and a suspension base supported in parallel to the rotation axis. A large number of press parts 10 and their assembling holes 11
And a vibration device provided on the suspension table side to impart vibration to the rotary shaft, and contact the surface of the rotary shaft with the surface of each press part 10 A spiral step portion is formed.

That is, in this liquid processing auxiliary device, a large number of press parts 10 each having an assembling hole 11 are inserted on the suspension shafts, and from the outside of each suspension shaft, as shown in FIG. The stepped portion provided on the rotary shaft applies a force that causes a partial up-and-down motion, and the suspension base side applies vibration from the suspension base side.

The steps of performing the liquid treatment of a large number of press parts 10 with this liquid treatment auxiliary device will be described in order below. First, as shown in FIG. 6, a large number of press parts 10 have suspension shafts (jig rods 4) in respective assembling holes 11 thereof.
By inserting 0), it becomes possible to hang the suspension shaft in a state in which no wasted space is produced, that is, in a state of being substantially overlapped. In other words, for one suspension shaft,
A large number of stamped parts 10 are efficiently suspended.

The suspension shaft on which a large number of press parts 10 are suspended is connected to the lower end of the suspension cassette constituting the suspension base by using a shaft support exchange member. Incorporate into the suspension base. At the lower end of this suspension base,
As shown in FIG. 6 and FIG. 7, since the rotary shaft provided with the spiral step portion on the outer peripheral surface is located, when the suspension cassette is incorporated into the suspension base, the outer peripheral surface of each press part 10 is In particular, the lower end surface comes into contact with the rotating shaft.

This rotary shaft is rotationally driven by a drive motor supported on the suspension base side, and when the rotary shaft rotates, a stepped portion (one of which is shown in FIG. 8) formed on the surface thereof. Part is shown as a representative), but will be moved to either the left or right in the figure. Since the outer surface of each press part 10 abuts on the step part on the rotation axis, the press part 10 on the upper side of the step part partially moves upward as shown in FIG. It becomes. In that case, the side surface close to the outer periphery of each of the assembling holes 11 moved upward is exposed to the processing liquid in the processing liquid tank without being hidden by the other press parts 10. As a result, the burrs generated on the outer circumference and inner circumference of each pressed part 10 are effectively removed.

At this time, the vibrating device provided on the suspension base side is activated, and vibration is mainly given to the lower part of the suspension base, so that the rotary shaft and the suspension shaft are also vibrated. The vibration force is also applied to each press component 10. As a result, the processing liquid can sufficiently permeate between the pressed parts 10 and the pressed parts 10
That is, the liquid treatment is sufficiently performed.

Therefore, this liquid processing assisting device gives an external and partial upward motion to a large number of press parts 10 on the suspension shaft by means of the step on the rotary shaft, and also vibrates by the vibrating device. By also providing, the liquid treatment can be effectively performed on each press part 10.

In addition, this liquid processing auxiliary device adopts a method in which a large number of press parts 10 are inserted into the suspension shaft by using the respective press parts 10 and are suspended from the suspension base as they are. As shown in FIG. 9, a spiral step may be brought into contact with the assembly hole 11 of each press part 10.

Therefore, in the liquid processing auxiliary device shown in FIG. 9, only the gear is provided on the rotating shaft without providing the step portion,
It is advisable to provide the step on a suspension shaft provided with another gear that meshes with this gear.

In the liquid processing auxiliary device thus constructed,
When the rotation shaft is rotated by the drive motor, the suspension shaft is rotated by the gear meshed with the gear on the rotation shaft. As shown in FIG. The component 10 is partially moved up and down. Of course, since the suspension shaft is vibrated by the vibrating device, as a result, the press parts 10 partially move vertically and vibrate with each other.

As described above, when each jig rod 40 is also used as the suspension shaft of the liquid processing auxiliary device, each jig rod 40 is as shown in FIG. It is formed as a straight rod with nothing on the surface,
Alternatively, as shown in FIG. 9, it is also formed by forming a spiral step on the surface.

When each pressed part 10 is used as a leaf valve of a shock absorber, these are shown in FIG.
It is possible to pull out the required number from the jig rod 40 and assemble the piston rod at the predetermined position as it is, without changing the insertion direction at all as it is.
