Embodiments of the present invention will be described in detail below with reference to the drawings.

As shown in FIG. 1 (A), a clip 1 according to the present invention, which is used for posture control, is formed of, for example, plastic, has a short first leg portion 2 and a long second leg portion 3, and has both legs at one end. While forming a U-shaped portion 4 connecting the parts,
At the other end, a free end 5 with both legs open is formed. Both legs 2 and 3 have tooth-shaped protrusions facing each other.

The attitude control device 6 for controlling the attitude of the clip 1 is, for example, as shown in FIG. 1 (B), a feeder 7 for sending a large number of clips to one, and the above-mentioned clips as commercial products. It is arranged between the automatic mounting device 8 for automatic mounting.

The feeder 7 sends, for example, a large number of clips 1 to one by centrifugal force or the like, and the attitude control device 6
Throw in. Therefore, the posture of the clip 1 delivered from the feeder 7 is at random, and as shown in FIG. 2, the first posture 1a with the free end 5 facing forward and the first leg portion 2 facing upward, and the free posture. A second posture 1b with the end 5 facing forward and the first leg 2 facing downward, and a third posture 1c with the U-shaped portion 4 facing forward and the first leg 2 facing upward.
And a fourth posture 1d in which the U-shaped portion 4 faces forward and the first leg portion 2 faces downward, the posture control device 6 is loaded with postures including four types.

Therefore, the posture control device 6 controls and converts the clip 1 inserted in the posture including the above four types into a desired posture, and loads the clip 1 into the magazine 9 so that the clip 1 can be aligned and fed out to the automatic mounting device 8. .. As shown in FIGS. 1 and 2, this magazine 9 comprises, for example, a circular or elliptical long rod 10 (it is advantageous to have an elliptical shape in order to prevent the inserted clip from freely rotating). , Has a conical guide portion 11 at the tip, and by dropping the clip 1 whose posture is controlled, the U-shaped portion 4 of the clip 1 is inserted into the rod 10 via the guide portion 11, and thereby a large number A large number of clips are held in a desired posture in a stacked state.

The attitude control device 6 of the present invention basically comprises:
As shown in FIG. 3, a guide path 12 for sequentially guiding and moving one clip 1 to be fed from the feeder 7 in a posture including four kinds, and a clip 1 in the guide path 12 is one of the four kinds. The sensor means 13 for detecting whether the posture is the posture, the clip 1 is in the first posture 1a or the second posture 1b described above (that is, the forward posture with the free end 5 facing forward), or the third posture described above. It is selected whether the posture is 1c or the fourth posture 1d (that is, the rearward posture in which the free end 5 is rearward), and the introduction path 14 for individually introducing the clips 1 in the selected posture, and the clip 1 subsequently. Is the first posture 1a or the third posture 1c (that is, the upward posture with the first leg portion 2 facing upward), or the second posture 1b or the fourth posture 1d (that is, the first leg portion). Two
The posture change path 15 for controlling to a desired specified posture by separately selecting whether the clip 1 is in a downward posture) and introducing the clips 1 in the selected postures separately and turning them to the right or left. And a discharge path 16 for discharging and dropping the attitude-controlled clip 1. Therefore, the magazine 9 is made to stand by under the discharge path 16, and the clip 1 controlled to have a desired posture falls from the discharge path 16 and is stacked and held in the magazine 9.

The above-described series of structures from the guide path 12 to the discharge path 16 is formed, for example, on the substrate 17, and the clip 1 is arranged by tilting (for example, about 32 degrees or more), so that the clip 1 is loaded by its own weight. Make it slide.

As shown in FIGS. 3 and 4, the guide path 12 constitutes a groove for sequentially guiding and moving the clip 1 in an at random attitude including the above four kinds of attitudes.
There is provided a blocking member 18 that can be blocked by traversing 2 midway. The blocking member 18 is driven by a driving means 19 such as an air cylinder and is movable back and forth with respect to the guide path 12. Therefore, the blocking member 18 is connected to the guideway 12
In the state in which the clip 1 has entered the position and the movement of the clip 1 has been blocked, the clip aligned in the guide path 12 is displaced upward by the subsequent clip sent from the feeder 7 and inserted into the guide path 12. Since there is a risk of jumping out, a closing plate 20 that closes the upper portion of the guide path 12 is provided.

As the blocking member 18 moves back and forth, the guide path 1
Clip 1 in 2 is allowed to move one by one and moves forward. Then, the clip 1 for the one piece that advances is then stopped by the stop member 21, and the stop member 21
It is driven by a driving means 22 such as an air cylinder and can move back and forth with respect to the guide path 12. As described above, the sensor means 13 for detecting which of the four types of postures the clip 1 is at rest is provided facing the guide path 12 in correspondence with the stop position.

The clip 1 whose posture is detected by the sensor means 13 is advanced by retracting the stop member 21 from the guide path 12. At this time, the blocking member 18 is also retracted from the guide path 12, the following clip is advanced toward one piece, and the stop member 21 is again moved.
Is stopped by. After that, the same operation is repeated, and the clip 1 addressed to each one is sequentially subjected to the posture detection by the sensor means 13.

As shown in FIG. 4, the end 12 of the guide path 12
The a is selectively communicated with the plurality of introduction paths 14 via the introduction path switching means 23. In the case of the illustrated example, the introduction path 14
Is composed of two introduction paths, a first introduction path 14a and a second introduction path 14b, and the introduction path switching means 23 is shaken by a driving means 24 such as an air cylinder at substantially the same time as the retracting operation of the stopping member 21. It is composed of a channel member that can be moved. Therefore, the attitude of the clip 1 detected by the sensor means 13 is the above-mentioned first attitude 1a.
Alternatively, in the case of the second posture 1b (that is, the forward posture with the free end 5 facing forward), as shown in FIGS.
2 and the first introduction path 14a, and the clip 1 is introduced from the guide path 12 into the first introduction path 14a. On the contrary, when the attitude of the clip 1 detected by the sensor means 13 is the above-mentioned third attitude 1c or fourth attitude 1d (that is, the rearward attitude with the free end 5 facing backward), 5 (C) (D), the driving means 2
4, the introduction path switching means 23 is positioned between the guide path 12 and the second introduction path 14b, and the clip 1 is advanced from the guide path 12 into the second introduction path 14b. Therefore, the drive means 24 changes the drive direction of the introduction path switching means 23 depending on whether the clip attitude detection signal received from the sensor means 13 is the forward detection signal or the backward detection signal,
The moving path of the clip 1 is switched.

The first and second introduction paths 14a and 14b are
The plurality of posture changing paths 15 are selectively communicated with each other through the forward changing posture changing passage changing means 25 and the backward changing posture changing passage changing means 26.

The posture changing path 15 which can be communicated with the first introducing path 14a is composed of two posture changing paths, a right turning posture changing passage 15a and a left turning posture changing passage 15b. The path switching means 25 is driven by the driving means 2 such as an air cylinder almost at the same time as the operation of the introduction path switching means 23.
It is constituted by a groove-shaped member which is swung by 7. Therefore, the posture of the clip 1 detected by the sensor means 13 is the above-described first posture 1a (free end 5).
Is in the forward position and the first leg portion 2 is in the upward position), as shown in FIG.
It is positioned between a and the right turning posture changing passage 15a, and the clip 1 is inserted into the right turning posture changing passage 15a from the first introduction passage 14a. On the contrary, when the posture of the clip 1 detected by the sensor means 13 is the above-mentioned second posture 1b (the posture in which the free end 5 is directed forward and the first leg portion 2 is directed downward), As shown in FIG. 5 (B), the drive means 27 positions the conversion path switching means 25 for the forward posture between the first introduction path 14a and the left turning posture conversion path 15b, and the clip 1 is moved to the first introduction path. 14a is made to enter into the counterclockwise posture changing path 15b. Therefore, this driving means 27
Changes the driving direction of the forward path conversion path switching means 25 depending on whether the clip attitude detection signal received from the sensor means 13 is the upward detection signal or the downward detection signal, and switches the movement path of the clip 1. I do.

The posture changing path 15 which can communicate with the second introducing path 14b is also constructed in substantially the same manner as described above.
That is, it is composed of two posture changing paths, that is, a right-turning posture changing path 15c and a left-turning posture changing path 15d. The rearward changing posture changing means 26 has an air cylinder or the like almost at the same time as the operation of the introducing way changing means 23. It is constituted by a groove-shaped member which is swung by the driving means 28. When the posture of the clip 1 detected by the sensor means 13 is the above-described third posture 1c (the posture in which the free end 5 is facing backward and the first leg portion 2 is facing upward), FIG.
As shown in (C), the driving means 28 positions the conversion path switching means 26 for the backward posture between the second introduction path 14b and the right-turning attitude conversion path 15c, and the clip 1 from the second introduction path 14b. Enter the right-turning posture changing path 15c. On the contrary, the posture of the clip 1 detected by the sensor means 13 is the above-mentioned fourth posture 1d (free end 5).
Is in a rearward position and the first leg portion 2 is in a downward position), as shown in FIG.
It is positioned between b and the counterclockwise posture changing path 15d, and the clip 1 is inserted into the counterclockwise posture changing path 15d from the second introduction passage 14b. Therefore, the driving means 28 changes the driving direction of the rearward posture conversion path switching means 26 depending on whether the clip posture detection signal received from the sensor means 13 is the upward detection signal or the downward detection signal, and the clip is performed. Switching of the movement route 1 is performed.

The action of controlling the posture of the clip 1 by the posture changing path 15 is shown in FIG. FIG. 2A shows
Right turn or left turn posture change path 1 via the first introduction path 14a
5a and 15b indicate the posture changing direction of the clip. As described above, the clip 1 in the first posture 1a
After being guided from the first introduction path 14a to the right-turning posture changing path 15a, is rotated 90 degrees in the clockwise direction R about the movement axis A there. On the other hand, the clip 1 in the second posture 1b is guided from the first introduction passage 14a to the counterclockwise posture changing passage 15b, and then rotated in the counterclockwise direction L by 90 degrees around the moving axis A there. Therefore, the clip 1 whose posture is controlled from the first posture 1a through the right turning posture conversion path 15a
Then, the clip 1 whose posture is controlled from the second posture 1b through the counterclockwise posture changing path 15b has the same posture after control.

The clip whose posture is controlled while entering from the second introduction passage 14b and passing through the right-turning or left-turning posture changing passages 15c and 15d is almost the same as the above. That is, FIG. 2 (B)
As shown in FIG. 3, the clip 1 in the third posture 1c is guided from the second introduction passage 14b to the right turning posture conversion passage 15c and then rotated 90 degrees around the movement axis A in the clockwise direction R. Be done. On the other hand, the clip 1 in the fourth posture 1d
Is guided from the second introduction path 14b to the counterclockwise posture changing path 15d, and then there is a 90-degree counterclockwise direction L about the movement axis A.
It is turned to. Therefore, the clip 1 whose posture is controlled from the third posture 1c through the right turning posture conversion path 15c,
The clip 1 whose posture is controlled from the fourth posture 1d through the counterclockwise posture changing path 15d has the same posture after control.

The structure of the posture changing passage 15 for changing the posture of the clip is easily implemented by forming the guide inclined surface on the side wall of the changing passage. That is, as shown in FIG. 6, both side walls of the right-turning posture changing path 15a are guide inclined walls 29a for gradually rotating the clip 1 in the first posture 1a in the clockwise direction around the movement axis, 29
b, the two guide inclined walls 29a and 29b gradually increase in angle in the moving direction of the clip.
Is rotated along the guide inclined walls 29a and 29b as it slides on the right-turning posture changing path 15a.

Both side walls of the left turning posture changing passage 15b form guide inclined walls 30a and 30b which are symmetrical with the both side walls of the right turning posture changing passage 15a, and the clip 1 is moved as the clip 1 moves. Gradually rotate counterclockwise around the axis.

It should be noted that FIG. 6 shows only the guide inclined walls of the right turning and left turning posture changing paths 15a and 15b following the first introducing passage 14a, and the right turning and left turning posture changing passages following the second introducing passage 14b. Although not shown in the drawings, 15c and 15d, the right turning and left turning posture change paths 15c and 15d following the second introduction path 14b.
6 is formed with a sloping guide wall that is symmetrical in FIG.

As shown in FIG. 4, the right-handed and left-handed posture changing paths 15a and 15b are combined with a discharge path 16a.
Is in communication with. Therefore, as described above, the clip 1 whose posture is controlled in the right-turning or left-turning posture changing paths 15a and 15b has a so-called lying-down posture.
6a. A drop path 32 is formed at the bottom end of the discharge path 16a so that it can be opened and closed by an opening / closing plate 31. The opening / closing plate 31 is opened / closed by a driving means 33 such as an air cylinder, whereby the clip 1 is dropped. Three
Drop from 2. In the case of the illustrated example, the sensor 34 provided in the vicinity of the drop path 32 detects the arrival of the clip 1,
Thereby, the driving means 33 is driven to open / close the opening / closing plate 31, and the clip 1 dropped from the drop path 32 is
The magazine 9 which is made to stand by just under the fall path 32
Insert it into the rod 10 of.

Similarly, the other right turn and left turn posture change path 1
5c and 15d are also connected to the discharge path 16b which joins them, and guides the clip 1 whose posture is controlled by the posture changing paths 15c and 15d to the discharge passage 16b in a so-called lying position as described above. .. At the bottom end of the discharge passage 16b, there is formed a drop passage 37 which can be opened and closed by an opening / closing plate 36, and the opening / closing plate 36 is driven by a driving means 3 such as an air cylinder.
The clip 1 can be dropped from the drop path 37 by being opened and closed by 8. A sensor 39 provided near the drop path 37 detects the arrival of the clip 1 and detects the driving means 3
In order to drive 8 to open / close the opening / closing plate 36, the clip 1 dropped from the drop path 37 is inserted into the rod 10 of the magazine 9 which is made to stand by immediately below the drop path 37.

The sensors 34 and 39 are connected to the driving means 19 of the blocking member 18 and the driving means 22 of the stopping member 21 described above, and the clip 1 addressed to each one is dropped into the falling path 3.
Each time it is dropped from 2 or 37, the blocking member 18 and the stop member 21 are moved back and forth. Therefore, the one-piece clip 1 stopped by the stop member 21 selectively passes through the introduction path (14a or 14b) and selectively turns to the right or left turning posture changing path (15a, 15b, 15c or 15d). And the posture is controlled and the fall path (32 or 37)
The clip 1 addressed to one piece, which is continuously stopped by the stop member 21 after being dropped from the above, is sent to the same path by the retreat of the stop member 21, and thus one piece is provided between the guide path 12 and the drop path 32 or 37. The addressed clip 1 is sequentially moved to control the posture.

As shown in FIG. 3, in one of the drop paths 32, the opening / closing plate 31 is configured to open the drop path 32 when it is moved in the downward tilt direction of the substrate 17, and therefore the clip 1 According to the open movement of the opening / closing plate 31, the posture is changed to a horizontal posture, and the work is dropped and can be preferably inserted into the magazine 9. However, when the opening / closing plate 36 opens the drop path 37 when the opening / closing plate 36 is moved in the upward tilt direction like the other drop path 37, it is difficult for the clip 1 to switch to a horizontal posture when falling. .. Therefore, in this case, as shown in another view in FIG. 3, the locking piece 4 is attached to the bottom end of the falling path 37 in the downward tilt direction.
0 is set. As a result, the clip 1 is closed until the opening / closing plate 36 finishes the opening movement and completely opens the fall path 37.
The locking piece 40 prevents the downward inclined end of the clip from immediately falling, and after the drop path 37 is completely opened, the clip 1 can be dropped while converting to a horizontal posture.

In the above embodiment, the clip 1 sent from the feeder 7 is loaded in the magazine 9 until the clip 1 is in the first posture 1a and the second posture 1.
Although the mechanism for automatically performing the posture control has been described from the at random postures including the four types of b, the third posture 1c, and the fourth posture 1d, the present invention fully automates the posture control mechanism. Besides, it can be semi-automated. For example, the clip 1 to be inserted into the guide path 12 is selected by a manual operation or an automatic device in a posture specified in advance as either a forward posture with the free end 5 facing forward or a backward posture with the free end 5 facing backward. By doing so, only the posture control thereafter can be configured to be performed by the present invention. Then, in this case, the device of the present invention is one of the forward posture or the backward posture that is specified in this way, that is, the upward posture with the first leg portion 2 facing upward and the downward posture with the first leg portion 2 facing downward. The at random position including two types is controlled to a desired position by the right turning posture changing path (15a or 15c) and the left turning posture changing path (15b or 15d), and the clip 1 of the controlled specific posture is discharged. It is configured to discharge from the passage (16a or 16b). That is, in this case, the present invention performs only the attitude control shown in either FIG. 2 (A) or (B).

Further, in the above-described embodiment, an embodiment is shown in which the clip 1 whose posture is controlled by the device of the present invention is loaded in a stack in the magazine 9 and the magazine 9 is loaded in the automatic loading machine 8. However, the clip 1 whose posture is controlled by the device of the present invention may be directly guided to the automatic mounting machine 8 and automatically mounted after being discharged from the discharge path.

A forward posture with the free end backward, a forward posture with the first leg of the forward posture or the backward posture facing upward, and a first leg of the forward posture or the backward posture with A guide path that sequentially guides and moves in a posture that includes four types of downward facing postures, a first introduction path and a second introduction path that are selectively communicated with the guide path, and the first introduction path is selected. A right-turning posture changing path and a left-turning posture changing path, which are made to communicate with each other, a right-turning posture changing path and a left-turning posture changing path which are selectively made to communicate with the second introduction passage, and which face the guide path, There are four types of clips in the guideway. A sensor means for detecting which of the postures the posture is, and a clip posture detection signal which is disposed between the guide path and the first and second introduction paths and which is received from the sensor means is a forward posture detection signal. Introducing path switching means for communicating the guiding path with the first introducing path, while communicating the guiding path with the second introducing path when the signal is a rearward attitude detection signal, the first introducing path, the right turning attitude changing path, and the left turning attitude. When the clip posture detection signal received from the sensor means is an upward posture detection signal, the first introduction path is connected to the right turning posture conversion path, and when the clip posture detection signal is a downward posture detection signal, the first introduction is provided. A switching path switching means for connecting the road to the left-handed posture changing path, and a clip posture which is arranged between the second introduction path and the right-handed posture changing path and the left-handed posture changing path, and which is received from the sensor means. When the detection signal is an upward attitude detection signal, the second introduction path is connected to the right turning attitude conversion path, and when the detection signal is a downward attitude detection signal, the second introduction path is connected to the left turning attitude conversion path. Provided in the pair of right-turning posture changing paths, and provided in the pair of left-turning posture changing paths, and right-turning means for rotating the upwardly oriented clip about 90 degrees clockwise around the movement axis. And a left-turning means for rotating the downwardly oriented clip about 90 degrees counterclockwise around the axis of movement, and ejecting the clip whose posture is controlled by the rotation from the right-handed and left-handed posture changing paths. An attitude control device for a clip, comprising: a discharge path. 2. A clip having a U-shaped portion formed by connecting both legs to one end of each of the first leg and the second leg and having a free end formed by releasing both legs at the other end of the clip, the free end being directed forward. In the posture specified as one of the forward posture and the backward posture in which the free end is rearward, there are two postures: an upward posture in which the first leg portion is directed upward and a downward posture in which the first leg portion is directed downward. An introduction path that can be sequentially moved in a posture including a type, a right-turning posture changing path and a left-turning posture changing path that can selectively communicate with the introduction passage, and a clip in the introduction path is one of the two types of postures. A sensor means for detecting which of the postures, and a clip posture detection signal which is arranged between the introduction path, the right turning posture changing path and the left turning posture changing path, and which receives the clip posture detecting signal from the sensor means is an upward posture detecting signal. When the introduction road is right A switching path switching means for communicating the introduction path with the left turning position conversion path when it is a downward position detection signal while communicating with the turning position conversion path, and a clip in the upward position provided in the right turning position conversion path. A right-turning means for rotating in a clockwise direction about 90 degrees around the moving axis, and a clip provided in the left-turning posture changing path, and rotating the clip in the downward posture about 90 degrees counterclockwise around the moving axis. An attitude control device for a clip, comprising: a left-turning means for biasing; and a discharge path for discharging a clip, the attitude of which is controlled by the rotation, from the right-turning and left-turning attitude changing paths.
