Description

[0001]
[Industrial application fields]
The present invention relates to a method and apparatus for assembling a large number of press parts punched by a press machine and having assembly holes into one jig bar.
[0002]
[Prior art]
For example, a press part 10 called a leaf valve as shown in FIG. 5 is used as a shock absorber part. The press part 10 which is this leaf valve has an assembly hole 11 for assembling to the piston rod of the shock absorber. In addition, the press part 10 having the assembly hole 11 includes Various things are used as parts of various machines and devices.
[0003]
Since such a pressed part 10 is often stamped by a press machine, as shown in FIG. 5A, burrs are easily generated, and these burrs must be removed by various methods. . For this reason, the present inventors have already proposed a liquid processing auxiliary device for removing burrs by chemical polishing as shown in FIGS. 6 to 9 in Japanese Patent Application No. 2001-220251. The basic concept of this liquid processing auxiliary device is that a large number of press parts 10 are inserted into one suspension shaft (also a jig bar 40 described later) through the assembly hole 11, as shown in FIG. As shown, the burrs of each pressed part 10 were exposed to the processing liquid existing around by partially moving up and down by a step on the rotating shaft.
[0004]
In this liquid processing auxiliary device, it is premised that a large number of press parts 10 are inserted into one suspension shaft, and the insertion work is because the press parts 10 are thin and small. Although it was done manually, it was very inefficient. That is, it is desired to automate the insertion of each pressed part 10 into the suspension shaft or the jig bar 40.
[0005]
In addition, when each of the pressed parts 10 is the leaf valve described above, it is known that if the assembly method is not constant, the function as the valve will vary due to individual characteristics. The component 10 must have a uniform pulling direction. This is because each press part 10 is generally slightly deformed in the punching direction.
[0006]
In other words, for this type of press part 10,
1. In order to efficiently perform liquid processing such as chemical polishing, the jig rod 40 must be inserted.
2. Each press part 10 needs to be assembled with its punching direction fixed in order to achieve a uniform function.
There is such a request.
[0007]
Therefore, the present inventors have completed the present invention as a result of various studies on how to satisfy the above requirements 1 and 2 for this type of pressed part 10.
[0008]
[Problems to be solved by the invention]
The present invention has been made in view of the above circumstances, and the problem to be solved is to automatically insert the press part into one bar, thereby allowing subsequent processing or assembly. It is to be able to do it effectively.
[0009]
[Means for Solving the Problems]
In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the embodiments described later.
“A method of assembling a large number of press parts 10 having the assembly holes 11 into one jig bar 40 through the following steps.
[0010]
(1) A step of feeding the material 12 to be punched from the pressed part 10 toward the press machine 200 and punching it.
(2) a step of transporting the press parts 10 on the table 20 while being accommodated in the processing part 12a of the material 12;
(3) When the stamping parts 10 came to drop hole 21 formed at the front end of the table 20, the vent dumping member 13 of the drop device 30 by reciprocating, downwardly over the pressure in the press part 10 Dropping step;
(4) The direction of the pressed parts 10 that have fallen is changed by the reciprocating movement of the drop-out member 13 whose axial center coincides with the center of the drop hole 21 on the jig bar 40 erected on the turntable 50. Without being inserted through each assembly hole 11 as it is;
(5) The turntable 50 is rotated to remove the jig bar 40 in which a predetermined amount of each pressed part 10 is incorporated, and after a new jig bar 40 is erected there, this or another jig bar The process of making the upper end of 40 face the drop hole 21 on the table 20 side "
It is.
[0011]
That is, according to the assembling method of claim 1, first, each press part 10 punched by the press machine 200 is stored in the processed portion 12 a (the hole punched by the press machine 200) of the material 12, and the table 20. It is transported to a predetermined position above and dropped from a drop hole 21 formed in the table 20, and the pressed part 10 to be taken out in the normal press machine 200 is removed from the material 12 in another place. It is something that was released.
[0012]
Further, each pressed part 10 that has fallen from the drop hole 21 is used on the jig bar 40 that is erected on the turntable 50 and whose upper end is waiting toward the drop hole 21. And it is inserted by dropping. Of course, even if the pressing component 10 comes on drop holes 21, to obtain and may not leave the processing unit 12a of the material 12, in the present invention, by the dropping device 30 on the falling hole 21, FIG. 2 The forcing-out member 13 as shown in Fig. 5 is forcibly removed .
[0013]
When the insertion amount of each pressed part 10 reaches a predetermined amount with respect to one jig bar 40 on the turntable 50, the turntable 50 is automatically rotated and the drop hole 21 on the table 20 side is rotated. Below, as shown in FIG. 2, a new jig bar 40 waits, and the jig bar 40 with a predetermined amount of the pressed part 10 inserted is removed from the turntable 50 as it is.
[0014]
If the jig bar 40 is the hanging shaft shown in FIG. 6 or the like, it is assembled to the hanging cassette as shown in FIGS. 6 to 9 with the press parts 10 being inserted. If the pressed part 10 that has been liquid-treated (chemically polished) in the state shown in FIGS. 6 to 9 is a leaf valve, it can be used as it is (without changing the assembly direction) as a piston rod. It is assembled.
[0015]
Therefore, according to the assembling method of claim 1, a large number of press parts 10 can be automatically incorporated into the jig bar 40, and the processing for each subsequent press part 10 and the punching direction of these press parts 10 are performed. Can be easily achieved.
[0016]
In order to solve the above-mentioned problem, the means taken by the invention according to claim 2 is similarly:
“A table 20 that carries a large number of press parts 10 punched out of the material 12 by the press 200 and having the assembly holes 11 while being accommodated in the processed portion 12a of the material 12, and assembled to the front end side of the table 20 When the press part 10 reaches the drop hole 21 formed on the front end side of the table 20, pressure is applied to the press hole 10 by reciprocation of the drop-out member 13 whose axial center coincides with the center of the drop hole 21. A dropping device 30 for dropping the material from the dropping hole 21 and a jig bar 40 which is disposed below the dropping device 30 and through which each press part 10 is inserted through the assembly hole 11 is detachably mounted. A device 100 for assembling the press part 10 into the jig bar 40, characterized by comprising the turntable 50 provided.
It is.
[0017]
That is, the assembling apparatus 100 according to the second aspect substantially realizes the assembling method according to the first aspect, and each press part 10 punched by the press machine 200 is in its original position. A table 20 that conveys the material 12 while being accommodated in the processing part 12a, and a turntable 50 in which the upper end of each jig bar 40 faces the drop hole 21 provided at the front end of the table 20 are provided. .
[0018]
According to the assembling apparatus 100, each press component 10 formed by punching the material 12 formed in a long strip shape or a strip shape by the press machine 200 is, for example, as shown in FIG. In addition, the material is transported on the table 20 while being stored in the processing portion 12a of the material 12 that is the punched hole. When each press part 10 is positioned in the drop hole 21 formed at the front end of the table 20, the drop member 13 is simultaneously blown out toward the press part 10 by the dropping device 30 disposed above the drop part 13. by and of being forced to disconnect came dropped, whereby the pressed part 10 is from falling hole 21 completely away from the processing unit 12a of the material 12 from falling down.
[0019]
Since the upper end of the jig bar 40 erected on the turntable 50 faces below the drop hole 21, each of the pressed parts 10 that have fallen is kept in a set without being separated from each other. The jig rod 40 is inserted through the attached hole 11. When a predetermined amount of the pressed part 10 is inserted on the first jig bar 40, this is detected by an optical sensor (not shown) and the turntable 50 rotates to feed the next jig bar 40. .
[0020]
Therefore, the assembling apparatus 100 according to claim 2 automatically performs assembling of each press part 10 into one jig bar 40, and facilitates subsequent liquid treatment of each press part 10, This facilitates assembly with a fixed directionality.
[0021]
The means taken by the invention according to claim 3 is as follows.
“There were 22 covers on the table 20 so that each pressed part 10 was positioned in the processed part 12a of the material 12”.
It is.
[0022]
That is, the assembling apparatus 100 according to claim 3 can carry out while pressing each press part 10 on the table 20 while being accommodated in the processing portion 12a while being covered by the cover 22 as shown in FIGS. It is what I did.
[0023]
Since this built-in device 100 is provided close to the press machine 200 that may generate a large vibration, the vibration is given to each press part 10 in the middle of conveyance, and it is detached from the processing portion 12a. Although it may not be parallel to the table 20, the built-in device 100 according to claim 3 prevents this by covering the press part 10 and the material 12 with the cover 22. is there.
[0024]
Therefore, the assembling apparatus 100 according to claim 3 can always convey each press part 10 in a parallel state with respect to the table 20, thereby stabilizing the drop from the drop hole 21 at the front end of the table 20. Moreover, it can be done reliably without turning the front and back.
[0025]
DETAILED DESCRIPTION OF THE INVENTION
Next, the invention according to each claim configured as described above will be described with respect to the assembling apparatus 100 according to the embodiment shown in the drawings. The assembling apparatus 100 includes the invention according to each of the above claims. In the following description, the embedded device 100 will be mainly described.
[0026]
FIG. 1 shows a schematic configuration of a press machine 200 for punching each press part 10 at a speed of 100 to 500 sheets / min, and an assembling apparatus 100 installed on the downstream side. As shown in FIG. 5, the press part 10 punched by the press machine 200 has a flat plate shape and has an assembly hole 11 at substantially the center, and has a belt-like shape as shown in FIGS. 1 to 3. It is punched from the metal material 12. The material 12 occupying the assembly hole 11 is automatically pulled out in the press machine 200, and the press part 10 itself is placed in the processed part 12a which is the punched hole. It is stored in.
[0027]
The material 12 is not limited to a long belt-like material as in the present embodiment, and may be, for example, a strip-like material. In any case, the material 12 may be continuously fed into the press machine 200. Any form may be used. Of course, the material 12 may have a width that allows only one piece as shown in FIG. 3, or a width that allows multiple pieces (in the embodiment, three pieces) as shown in FIG. Also good.
[0028]
The table 20 is capable of transporting the material 12 as described above horizontally, and as shown in FIG. 2, a drop hole 21 for dropping each press part 10 is formed at the front end thereof. 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 the width, but a large number can be picked up. In order to correspond to the material 12, as shown in FIG.
[0029]
Further, as shown in FIG. 3 or FIG. 4, the table 20 is formed with a cover 22 that wraps each pressed part 10 together with the material 12. When the dropping device 30 to be described later performs forced removal simultaneously with air blowing, in order to allow the blowing air to be directly blown to each press part 10 together with the insertion of the removal member 13, As shown in FIGS. 3 and 4, the cover 22 has a ventilation space 22 a. Through this ventilation space 22 a, the drop-off member 13 directly presses the upper surface of each press part 10, and air from the dropping device 30 is directly blown to each press part 10.
[0030]
Since this built-in device 100 is provided close to the press machine 200 that may generate a large vibration, this vibration is given to each press part 10 in the middle of conveyance. By covering the material 12, it is possible to prevent the pressed parts 10 from coming off the processed portion 12a due to the applied vibration and not being parallel to the table 20, and the drop hole 21 at the front end of the table 20 is prevented. This makes it possible to stably drop the unit from the outside without turning it upside down.
[0031]
Drop device 30, in this embodiment, as described above, for the press part 10 has come on the drop hole 21, which performs pressing by vent off member 13, thereby, each press parts 10 material Ru der which completely away as from 12 of the processing unit 12a.
[0032]
Now, below the drop hole 21, the tip of the jig bar 40 for inserting the pressed part 10 that has been dropped into the assembly hole 11 must be waiting. This is the turntable 50 shown in FIG. 1 or FIG. Of course, these turntables 50 can be rotated with respect to the center thereof, and can also be linearly moved in a certain direction.
[0033]
The turntable 50 shown in FIG. 1 is configured such that a large number of jig bars 40 can be attached in a radial manner, and the upper ends of these jig bars 40 can be sequentially opposed to one drop hole 21. It is what I did. The turntable 50 shown in FIG. 4 is adapted to handle a case where a plurality of (three) material 12 can be used, and is one in which three jig bars 40 are erected in one radial shape. It 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 has a shape as shown in FIG. As a result, the press parts 10 positioned at the three types of positions indicated by the phantom lines in FIG. 4 are individually inserted into the jig bar 40.
[0034]
As shown in FIGS. 6 to 9, a large number of press parts 10 inserted into one jig bar 40 by the above-described assembling apparatus 100 have the one jig bar 40 as a suspension shaft. It is mounted on the liquid processing device. The outline and function of this liquid processing apparatus will be described as follows.
[0035]
As shown in FIG. 6, this liquid processing auxiliary device is for performing liquid processing such as deburring by chemical polishing and various types of cleaning on the press part 10 having the assembly hole 11. A suspension base in which the lower end is immersed in the treatment liquid tank, a rotating shaft supported in a substantially horizontal state below the suspension base, and a press part supported by the suspension base so as to be parallel to the rotation axis 10 is constituted by a suspension shaft that is inserted and supported by each assembly hole 11 and a vibration device provided on the suspension stand side to impart vibration to the rotation shaft, and on the surface of the rotation shaft, A spiral stepped portion that comes into contact with the surface of each pressed part 10 is formed.
[0036]
That is, this liquid processing auxiliary device has a large number of press parts 10 having assembly holes 11 inserted through the suspension shafts, and from the outside of each suspension shaft, as shown in FIG. The step portion provided in the sway provides a force that causes a partial vertical motion, and the suspension shaft is subjected to vibration by the vibration device from the suspension stand side.
[0037]
The steps of performing liquid processing of a large number of press parts 10 using this liquid processing auxiliary device will be described in order as follows. First, as shown in FIG. 6, a large number of press parts 10 have a useless space with respect to the suspension shaft by inserting the suspension shaft (jig bar 40) into each assembly hole 11. It can be suspended in a state that does not occur, that is, in a substantially overlapped state. In other words, a very large number of press parts 10 are efficiently suspended from one suspension shaft.
[0038]
A suspension shaft that suspends a large number of press parts 10 is connected to a lower end of a suspension cassette that constitutes a suspension base using a shaft support exchange member, and this suspension cassette is connected to the suspension base. Include. As shown in FIG. 6 and FIG. 7, a rotating shaft provided with a stepped portion having a spiral shape on the outer peripheral surface is located at the lower end of the suspension base. The outer peripheral surface of each pressed part 10, particularly the lower end surface, comes into contact with the rotating shaft.
[0039]
This rotating shaft is rotationally driven by a drive motor supported on the suspension base side. When this rotating shaft rotates, a step portion formed on the surface thereof (in FIG. 8, a part thereof is representative). Will move to either the left or right side of the figure. Since the outer surface of each press part 10 comes into contact with the step portion on the rotating shaft, the press part 10 on the upper side of the step portion partially moves upward as shown in FIG. It becomes. If it becomes so, the side surface near the outer periphery of each assembly hole 11 which moved up will be exposed to the process liquid in a process liquid tank, without being hidden by the other press components 10. FIG. Thereby, the burr | flash which generate | occur | produced in the outer periphery and inner periphery of each press component 10 is removed effectively.
[0040]
At this time, the vibration device provided on the suspension base is operated, and vibration is mainly applied to the lower part of the suspension base, so that the rotating shaft and the suspension shaft are also vibrated. A vibration force is also applied to the component 10. As a result, the processing liquid can sufficiently permeate between the press parts 10, and the liquid processing of the press parts 10 is sufficiently performed.
[0041]
Therefore, this liquid processing auxiliary device gives an external and partial upward motion to the multiple press parts 10 on the suspension shaft by the step portion on the rotation shaft, and also gives vibration by the vibration device. Thereby, the liquid processing with respect to each press part 10 can be performed effectively.
[0042]
Further, this liquid processing auxiliary device adopts as it is that a large number of press parts 10 are inserted on the suspension shaft using the respective press parts 10 and are suspended from the suspension base as shown in FIG. As shown, a spiral step may be brought into contact with the assembly hole 11 of each press part 10.
[0043]
Therefore, in the liquid processing auxiliary device shown in FIG. 9, only the gear is provided on the rotating shaft and the step portion is not provided, but the step is provided on the suspension shaft provided with another gear that meshes with this gear. It is good to provide a part.
[0044]
In the liquid processing auxiliary device configured as described above, when the rotation shaft is rotated by the drive motor, the suspension shaft is rotated by the gear meshing with the gear above it, and the step portion on the suspension shaft As shown in FIG. 8, each press part 10 partially moves up and down. Of course, since the suspension shaft is subjected to vibration by the vibration device, as a result, the press parts 10 partially move up and down and vibrate with each other.
[0045]
As described above, when each jig bar 40 is also used as a suspension shaft of the liquid processing auxiliary device, each jig bar 40 has a surface as shown in FIG. It is formed as a straight rod having nothing, or as a spiral stepped portion formed on the surface as shown in FIG.
[0046]
When each press part 10 is used as a leaf valve of a shock absorber, the necessary number is not changed from the jig bar 40 while maintaining the state as shown in FIG. It is extracted and assembled as it is at a predetermined position of the piston rod.
[0047]
