Description

DETAILED DESCRIPTION OF THE INVENTION Field of Use and Summary of the Invention The present invention relates to a method for aligning spokes used in a device for inserting a spoke into a spoke hole of a hub and the like, and a device for carrying out this method, in particular, a spoke embossing method. When the spokes ejected from the bending device penetrate through the collar of the hub, they are aligned in the direction of gravity without being entangled with each other.The entanglement prevention and alignment work can be performed at high speed with a simple structure. It is something that can be converted.

For this purpose, the spokes penetrating the brim portion are temporarily set in the free state as described above, so that the posture is controlled in the alignment direction.

[Prior Art and Problem] As a device for inserting the spokes into the flange portion of the hub, a device in which the hubs are supported so that the shaft portions thereof are in a horizontal posture and the respective spokes are inserted therein is disclosed in Japanese Patent Laid-Open Publication No. Sho 58-58. -50094
It is proposed in Japanese Patent Publication No. 4.

This has the advantage that spokes can be inserted into both collars at the same time as compared with the conventional self-weight type. In this horizontal support type spoke insertion device, as shown in FIG. 17, the hub (1) is supported horizontally, and the spokes (S) are arranged on both sides of the hub (1) by means of a launching device. The spoke holes (11) and (12) formed in the collar portions (10a) and (10b) of 1) are inserted from the side. The insertion direction of the spokes (S) is specially set as shown in the same figure so that the spokes (S) can be inserted from the side, and each of the punching devices has a corresponding position with respect to the corresponding spoke hole. Is set to operate properly, and by repeating the "positioning driving operation", the spokes (S) are automatically inserted into the spoke holes of the hub.

That is, as shown in the same figure, the first launching device (2a) installed on the left side of the hub (1) is installed in the spoke hole (11) of the flange portion (10a) of the hub (1) supported in a horizontal position. The spokes (S) are pushed in, and the spokes (S) are inserted into the spoke holes (12) by the second launching device (2b) installed on the right side of the hub (1). In the spoke hole (11) of the other collar (10b), the third installed on the right side of the hub (1).
The spoke (S) is inserted by the launching device (2c),
No. 4 installed on the left side of the hub (1) in the spoke hole (12)
The spokes (S) are inserted by the driving device (2d). Further, the posture of the driving device is set so that these insertion directions do not cross each other and the insertion locus of the spoke (S) and its extension line do not come into contact with the flange portion on the opposite side.

As a device for launching this spoke, the one proposed in Published Patent Publication No. Sho 58-500991 is adopted, and even in this launch device, the spoke (S) is placed at the final position. Can not be inserted. That is, as shown in FIG. 18, a so-called incomplete insertion state in which the vicinity of the bent head (H) remains on the front side in the insertion direction is obtained. Therefore, in this conventional device, as shown in the same figure, a spoke retracting device (8a) is added so as to oppose each spoke ejecting device. This device holds the tips of the spokes (S) ejected from the embossing device so as to be inserted into the spoke holes of the collar and moves the retaining parts in a predetermined direction. As a result, the spoke (S) in the fully inserted state is inserted to the final position. When the holding of the spokes by the holding portion is released, the spokes (S) are aligned in a suspended state due to their own weight as shown by the broken line in the figure.

However, in this conventional device, there is a problem that it takes a long time from when the spokes (S) are driven from the driving device to when they are aligned in the final insertion posture. Further, there is a problem that the spokes (S) are difficult to be aligned in a hanging state.

This is because the spoke pull-in device (8a) holds the spoke (S) at the incompletely inserted position by a holding part provided at the tip of the movable part and pulls it in the spoke insertion direction. This is because it is necessary to perform the pulling-in operation after securely pinching, and this series of operations cannot be speeded up. Further, time is required to return the holding portion to the initial position, and even if the time required for launching by the spoke launching device can be shortened, the time required for the spoke inserting operation is limited by the time required for the retracting operation. This is because it cannot be shortened.

Also, when the bent head (H) is pulled in with the posture facing upward or sideways, when the posture changes to the drooping state, the vicinity of the bent head (H) becomes a resistance to this posture change.

The present invention has been made in view of the above point, and "moves the spoke (S) inserted in the incomplete insertion position into the spoke hole of the hub (1) supported in the horizontal position to the final insertion position. Spoke alignment method of a spoke insertion device for aligning in a drooping posture or a device for carrying out the same ”,
An object of the invention is to shorten the time required to control the attitude of the spoke (S) to the final insertion position and to surely change the attitude to the final insertion attitude.

． Regarding the Invention of Claim 1 [Technical Means] The technical means of the present invention taken to solve the above-mentioned problem is to set the insertion locus of the spokes (S) to a straight line descending obliquely, and then the spokes (S). Most of this is a hub (1)
After being inserted in an incompletely inserted state that penetrates the collar portion of the spoke (S), the portion of the spoke (S) passing through the collar portion is temporarily lifted in a freely movable or self-rotating state, and the degree of oblique descending of the spoke axis is moderated. Then, the lifting force was released. ”

[Operation] The above technical means of the present invention operates as follows.

When the spokes (S) are inserted into the spoke holes of the hub in a predetermined posture, the tip side of the spokes (S) penetrates through the spoke holes of the flange and the area closer to the tip end than the vicinity of the base end of the spoke (S) is It projects through from the brim. That is, the position is an incomplete insertion position. At this time, most of the spokes (S) penetrate through the spoke holes, and the tip ends of the spokes (S) tend to descend obliquely due to their own weight. (See (A) of FIG. 1) After that, when the portion of the spoke (S) that has passed through the collar portion, that is, the collar portion passage section is temporarily lifted, the spoke supporting state of this lifting force imparting portion Is in a self-rotating state or a rolling movable state, on the other hand, since there is a fitting margin between the spoke hole and the spoke (S), this allows the entire spoke (S) to have its axis line. It is supported in a state in which it can rotate freely around the center or a state in which it can freely roll. Further, even in this supporting state, the spokes (S) are in a posture of descending diagonally, and therefore are urged in the insertion direction by their own weight. (See (B) in FIG. 1) By the way, the spoke (S) has a bent head (H) at the base end side.
As described above, in the state in which the bending head (H) is rotatably or rotatably supported, as described above, the bending head (H) is hung downward from the spoke (S) axis due to its own weight. The posture changes. As a matter of course, when the bent head (H) is in the downward posture from the beginning, it is maintained as it is.

After that, when the lifting force of the spokes (S) is released, the front ends of the spokes (S) at the incompletely inserted position descend and rotate due to their own weight. Since the bending point from the straight portion of the spoke (S) to the bending head (H) is an arcuate portion having a constant curvature, and since the bending head has a downward posture, As for the spoke (S), the arcuate portion passes through the spoke hole due to the downward rotation of the tip side, and finally only the brim portion of the bent head (H) is not penetrated and the entire spoke is from the brim portion. It becomes a drooping posture. In other words, they have been inserted and aligned at the final insertion position. (See (C) of FIG. 1) When the above-mentioned operation is performed for each spoke (S) every time the spoke (S) is inserted into the spoke hole of the collar portion, each spoke (S) inserted at the incompletely inserted position ( S) will be sequentially arranged.

[Effects] The present invention having the above-described configuration has the following unique effects.

Regardless of the posture of the bending head (H) when the spoke (S) is inserted into the spoke hole of the hub, the posture is controlled and the spoke (S) is moved to the final insertion position. In the final state, the spokes (S) surely change to the aligned posture (drooping posture).

Since only a part of the spokes (S) is lifted and then opened in order to shift from the incompletely inserted position to the aligned posture, the time required for the alignment can be shortened as compared with the conventional one.

． Regarding the invention of claim 2, the present invention relates to a spoke (S) aligning device for carrying out the invention of claim 1, which solves the same problem as the invention of claim 1, and It is an object of the present invention to make it possible to smoothly carry out the method of the invention.

[Technical Means] The technical means of the present invention for solving the above-mentioned problem is to set "the insertion locus of the spoke (S) to a straight line that descends obliquely, and to fix it outside the flange portion of the hub (1). The moving piece (80) is arranged in the front end side protruding area of the spoke (S) in the completely inserted state, and the moving piece (80) is vertically driven by a driving means (87) along a predetermined locus to move the moving piece (80). The upper end of the (80) is a support side (89) which is linear or curved and supports the spoke (S), and the movement path of the support side (89) for one cycle is incompletely inserted into the spoke (89). The driving means (87) is set so that the spoke (S) moves out from the lower region to the upper region and then escapes from the descending rotation trajectory of the spoke (S). To operate at least one cycle ”.

[Operation] The above technical means of the present invention operates as follows.

When the spokes (S) are in the incompletely inserted state, the driving means (87) starts to operate, and the portion protruding from the flange portion of the hub (1) is temporarily moved by the supporting side (89) of the moving piece (80). It is supported and lifted from below. At this time, since the tip of the supporting side (89) is linear or arcuate, the spokes (S) are rotatably supported by the supporting portion, and the spokes (S) are movably supported. For the same reason as in the case of the invention, the entire spoke (S) is supported in a free state, and the bending head (H) is corrected to a downward posture.

After that, the support side (89) is made to escape from the descending rotation locus of the spoke (S) by the operation of the driving means (87), whereby the supporting state is released and the tip side of the spoke (S) descends. It is rotated and aligned in a predetermined posture.

Each time the spoke (S) is inserted into the collar portion of the hub (1) and becomes incompletely inserted, the moving piece (80) performs the series of operations described above, and thus the spoke inserted into the collar portion of the hub (1). (S) will be sequentially arranged.

[Effects] The present invention having the above-described configuration has the following unique effects.

The method according to the invention of claim 1 is smoothly carried out, and has the same effect as the invention of claim 1. Also, drive means (87)
Since it is composed only of the moving piece (80) of (4), the device for aligning the spokes becomes simpler than the conventional device.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS.

Also in this embodiment, the hub (1) is similar to the conventional one described above.
The spokes (11) are formed on the collar part and the spokes (S) are inserted from the outside, and the spoke holes (12) where the spokes (S) are inserted from the inside of the flange part, respectively, correspond to each other. Each of the launching devices (2) is arranged outside the hub (1). Incidentally, in the above-mentioned conventional example, each punching device is made to correspond to the spoke hole located on the side portion of the collar portion, but in this embodiment, as shown in FIG. Each punching device is associated with a hole.

As a result, the collar portion (10a) supported and fixed in a horizontal posture
The spokes (S) can be individually inserted into the spoke holes (11) and (12) of (10b) so as to fit the respective spoke holes.

When the spokes are inserted by the above-mentioned punching device, it is necessary to match the insertion locus of the spokes (S) from each punching device with the spoke holes (11) (12). The driven drive roller is rotationally driven by the stepping motor (SM), and when it coincides with the spoke holes arranged in the collar, the stepping motor (SM) is stopped by the output signal from the position detection device (40). At the same time, the air cylinder (41) is provided with a positioning device for retracting the position detecting device (40) from the detection position to the retracted position.

Next, each embossing device has a structure as shown in FIGS. 6 and 7, and the holder (D) provided with the groove (3) is fixed to the frame of this embossing device and the holder (D ) Is connected to a connecting cylinder part (G) in which a nozzle (N) is externally fitted so as to move forward and backward, and as a reciprocating drive means between the connecting cylinder part (G) and the holder (D). The air cylinder (38) is installed.

As shown in FIG. 6, the holder (D) has a groove (3) that opens upward, and is arranged below the chute (61) of the spoke (S) supplying device to the launching device and below it. The open portion of the groove is aligned with the downstream end of the chute (61), and the length of the open portion is longer than the length of the spoke (S).

In this embodiment, when the spokes (S) are received in the groove (3), the air cylinders (34) (3)
4) drives the cover plate (30) to close the groove (3), and in this state, the discharge port (3) provided at the upstream end of the groove.
The spokes (S) are ejected at a predetermined timing by ejecting pressurized air from 1), that is, by the thrust of the air pressure. Incidentally, (37) is a movable lid for increasing the thrust.

For this purpose, a solenoid valve (V ₀ ) is inserted in the air pressure circuit (50) from the air pressure source to the discharge port (31), and this solenoid valve (V ₀ ) is inserted.
The lid plate (30) is opened and closed by the control means (5). In order to set these opening / closing timings to predetermined values, the first control device (5) outputs to the first detection device (52) and the occlusion detection sensor (53) arranged as shown in FIG. The output from the spoke detection sensor (54) provided as shown in FIG. 7 is input. The open detection sensor detects that the cover plate (30) has returned to the fully open position, and the other closing detection sensor detects that the cover plate is in the fully closed state. On the other hand, the spoke detection sensor (54) detects that the spoke (S) has been inserted into the groove (3).

As shown in FIG. 8, the first control device (5) inputs the output from the spoke detection sensor (54) to the set input terminal and the output from the blockage detection sensor (53) to the reset input terminal. A flip-flop circuit (hereinafter referred to as the first FF circuit (55)), an output of the first FF circuit (55) to a set input terminal, and an output from the open detection sensor (52) to a reset input terminal. And a flip-flop circuit (hereinafter referred to as the second FF circuit (56)). The output from the first FF circuit (55) is input to the advance drive circuit (57), while the output from the second FF circuit (56) is returned to the return drive circuit (58) via the delay circuit (59).
Has been entered in.

The output from the advance drive circuit (57) and the output from the return drive circuit (58) are input to the air cylinders (34) (34). The output from the delay circuit (59) and the output from the second FF circuit (56) are input to the solenoid valve (V ₀ ) via the OR circuit.

Therefore, when the spoke (S) is thrown into the groove (3), the advancing drive circuit (57) operates by the output from the spoke detection sensor (54), the lid plate (30) advances, and the groove (3) is moved. Block. At the completion of this blockage, the output of the blockage detection sensor (53) resets the first FF circuit (55), and the output of the second FF circuit (56) at this time opens the solenoid valve (V ₀ ) to release the pressure air. Is discharged from the discharge port (31). After that, the discharge of the pressurized air continues, and when the set time of the delay circuit (59) elapses, the output of the return drive circuit (58) drives the air cylinders (34) (34) to return and the cover plate (30) moves. The pressurized air is continuously discharged until it returns to the fully open position.

A posture control function is added to the groove (3), and the bending head (H) of the spoke (S) moves as the spoke (S) moves.
The cross section of the groove portion (3) is configured so that the member is in an upright posture. In other words, the side wall of this groove has an inclined surface that is smoothly twisted from the horizontal surface to the upright surface.

With the above configuration, when the spokes (S) are thrown into the groove (3) from the chute (61) at a constant timing, the spokes (S) thrown into this groove are automatically driven by the driving device and driven. The bent spokes (S) are inserted into the spoke holes of the brim with their bent heads (H) standing upright. In addition, in this embossing step, the protruding position of the nozzle (N) is close to the corresponding spoke hole, and when the embossing of the spoke (S) is completed, most of the spoke (S) has penetrated the spoke hole. Become.

As shown in FIG. 2, four aligning devices (8b) (8b) are arranged outside the brim in the middle of the insertion path of the spokes (S), and each aligning device (8b) rotates. It consists of a swing arm (81) that swings around an axis and a stepping motor (82) that drives the swing arm (81). The swing plane (P) of this swing arm (81) is inserted into the spoke (S). It is a plane that is perpendicular to the locus and extends vertically. And this swing arm (8
1) corresponds to the moving piece (80) of the means of the present invention, and the upper end of the swing arm (81) serves as the support side (89).

The central axis of the swing arm (81) is set parallel to the insertion locus of the spoke (S), and the stepping motor (82)
Is connected to the output shaft of. Further, in this embodiment, the support side (89) is an arcuate portion having a small curvature which is concave downward.

The reciprocating rotation angle of the stepping motor (82) is set to a predetermined angle as shown in FIG. 3, and the swing arm (81) reciprocally rotates by a constant angle in the range from top dead center to bottom dead center. Be punished. Then, at the top dead center, the supporting side (89) is positioned slightly above the spoke (S) insertion locus, and at the bottom dead center, the supporting side (89) is located below the spoke (S) insertion locus. Return to the escaped position.

In this embodiment, the one-cycle operation of the swing arm (81) is
The operation is in the range of the bottom dead center and the top dead center and the bottom dead center. The output of the sensor (88) is set to drive, and when the spoke (S) is inserted into the spoke hole and its tip projects from the spoke hole, as shown in (a) of FIG. Is input to the drive circuit (86). The drive circuit (86) sets a normal rotation drive angle, a reverse rotation drive angle, and drive speeds thereof, and inputs a normal rotation or reverse rotation drive signal to the stepping motor (82) according to the output from the sensor (88), The stepping motor (82) is operated to rotate forward by a fixed angle and then reversely rotate by the same fixed angle to stop.

Swing arm (81) of the alignment device (8b) configured as described above.
Rotates in association with the spoke launching action of the launcher. Then, in the initial state, the swing arm (81) is at the position "I" in FIG. 3, and the spoke (S) is hammered out from the corresponding hammering device, and the tip side of the spoke (S) projects from the spoke hole. Then, the output of the sensor (88) causes the stepping motor (82) to start forward rotation at this point, and when the spoke (S) is in the incompletely inserted state, it moves to the position "II" in FIG. The supporting edge (89) at the upper end of the swing arm (81) is located near the top dead center and supports the spoke (S) at this point. After that, when the swing arm (81) further rises and the supporting side (89) reaches the top dead center, "II" in FIG.
I "or, as indicated by the broken line in FIG. 4 (a), the spokes (S) supported thereby are lifted in a state in which the inclination degree is loose, and the bending head (H)
Posture changes due to its own weight. When the support side (89) is returned and rotated from the top dead center to the bottom dead center, the support side (89) is located out of the insertion path of the spoke (S). As shown in c), the spoke (S)
Is lowered and rotated by the above-described action to be in an aligned state.

In order to facilitate the descending rotation of the spoke (S) to the final alignment position as described above, as shown in FIGS. 9 and 10, the swing plane (P) of the swing arm (81) is used. ) Spoke (S)
It is conceivable to incline with respect to the insertion locus and set so that the top dead center side is located on the tip side of the spoke (S) with respect to the bottom dead center. In this case, when the spoke (S) in the incompletely inserted state is temporarily lifted, a moving force toward the tip side is given to the spoke (S), and the insertion of the spoke (S) is performed. Even if the degree is insufficient, the insertion degree is deepened by this moving force, and the descending rotation of the tips of the spokes (S) is smoothly performed. Particularly, in the case of this embodiment, when the entire surface of the supporting side (89) of the swing arm (81) is made of a material (M) having a large friction coefficient such as rubber, the movement of the supporting side (89). Thus, there is an advantage that the thrust when the spoke (S) is moved to the predetermined insertion position becomes relatively large, and the spoke (S) can be reliably moved to the final insertion position.

In the above-mentioned embodiment, the moving piece (80) is the swing arm (81) which reciprocally rotates about the rotation axis by a predetermined angle, but as shown in FIGS. It may be an elevating rod (83) in which the connecting portion of the upper rod (86) and the lower rod (87) is in a state of being bent in a middle direction after being raised as desired. In this case, the elevating rod (83) is moved up and down by a reciprocating drive means (84) such as an air cylinder that moves up and down at the same timing as the stepping motor (82) of the first embodiment, and the elevating rod (83 Of the bendable part and the guide tube part (85) so that the bendable part in the middle of it is projected to the upper end open part of the guide tube part (85) when 83) is raised to the top dead center. Set up relationships.

In the case of this example, when the lifting rod (83) is raised while being positioned inside the guide tube portion (85), it is incompletely inserted at the position immediately before top dead center as shown by the broken line in FIG. As shown by the solid line in the figure, the tips of the spokes (S) are temporarily lifted, and then the bendable part of the lifting rod (83) protrudes from the upper end of the guide tube part (85). The upper rod (86) above the bendable portion falls toward the tip side of the spoke (S), and the support side (89) at the tip of the lifting rod retracts to a position separated from the tip of the spoke (S). . Then, the spokes (S) can be lowered and rotated, and the spokes (S) are aligned as in the case of the above embodiment.

In the case of this embodiment as well, in order to control the reciprocating drive means (84), the spokes (S) are inserted into the spoke holes and the tips thereof project from the spoke holes, as in the case of the first embodiment. Then, a combination of a sensor (88) which is in an output state and a drive circuit (86) which receives the output and outputs a drive signal to the reciprocating drive means (84) is adopted.

． About invention of Claim 3 This invention relates to the apparatus which implements the invention of Claim 1 like the invention of Claim 2, and supports the spoke (S) in an incompletely inserted state rotatably by air pressure. As a result, the attitude of the spoke (S) at this point is smoothly changed.

[Technical Means] A technical means for solving the above-mentioned problem is to set the insertion locus of the spoke (S) to a straight line that descends obliquely, and to define the tip side protruding area of the spoke (S) in the incompletely inserted state. A control device (91) that opens the air discharge port (90) upward at the lower side and temporarily discharges the pressure air from the air discharge port (90) when the spoke (S) is in the incompletely inserted state. The air discharge pressure from the air discharge port (90) is set so that the tip end side of the spoke (S) in the incompletely inserted state can be slightly lifted.

[Operation] The above technical means operates as follows.

When the spokes (S) are inserted into the collar portion of the hub (1) in an incompletely inserted state, pressurized air having a predetermined pressure is discharged from the air discharge port (90) and is temporarily lifted.
Since this supporting state is due to air pressure, the straight portions of the spokes (S) are rotatably supported. In this state, the spokes (S) are rotatably supported as a whole. As a result, the posture of the bent head (H) is changed, and thereafter, when the discharge of the pressurized air is stopped, the supporting force disappears and the spokes (S) are rotated downward and aligned.

Then, each time the spokes (S) are inserted, the operation is performed and the spokes (S) are sequentially arranged.

[Effects] The present invention having the above-described configuration has the following unique effects.

Since the spokes (S) are supported by the compressed air in a free state, the bending head (H) of the spokes (S) is faced downward, and the resistance during the posture changing motion is reduced. Will be carried out more smoothly.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 13 to 16.

In this embodiment, the spoke launching device is of pneumatic type as in the first embodiment, and as shown in FIG.
The air pressure source used for this launching device is as it is as an air pressure source for changing the attitude of the spoke (S), and a branch circuit (51) branched from the downstream side of the solenoid valve (V ₀ ) of the air pressure circuit (50). An air outlet (90) is provided at the tip of the.

Therefore, in this embodiment, the circuit for controlling the solenoid valve (V ₀ ) provided in the first control device (5) of the first embodiment functions as it is as the control device (91), and the spokes (S) are launched. The pressure air is discharged from the air discharge port (90) until the cover plate (30) is ejected from the device and returned to the fully open position.

In this case, the discharge time of the pressure air for the driving operation of the spokes (S) and the discharge time of the pressure air for aligning the discharged spokes (S) are the same. Since the ejection operation of S) is performed instantaneously, a constant air ejection time can be secured even after the ejection of the spokes (S) is completed, and the initial alignment operation is performed. Then, after the pressurized air is temporarily lifted as shown in Fig. 14 while being discharged from the air discharge port (90), at the end of discharge, as shown in the same figure, the tip of the spoke (S) is The part descends and rotates. The position of the air discharge port (90) is set slightly off the descending locus of the spoke (S) as shown in FIG. The air outlet (90) does not get in the way during operation.

Further, as shown in FIG. 15, when the air discharge port (90) is arranged in the downward movement trajectory of the spoke, the end face may be set to be oblique or arcuate. Even if the air discharge port (90) is present in the descending rotation path of the spoke (S), it slides down the end face of the air discharge port and descends to the final position when the spoke (S) descends and rotates. Is.

Incidentally, as shown in FIG. 16, a branch valve (51) is branched from the upper end side of the solenoid valve (V ₀ ) and the branch valve (51) is intermittently opened at regular time intervals. (V ₁ ) may be inserted.

In this case, the pressure air is discharged from the air discharge port (90) intermittently at regular intervals, and the pressure is applied when the spoke is ejected from the ejector of the spoke (S) and the spoke is incompletely inserted. The posture of the spokes (S) is controlled when air is discharged, and then the spokes (S) are lowered and aligned when the discharge of the pressure air is stopped.

In any of the above cases, if the air discharge port (90) is set obliquely upward, the above-mentioned alignment operation proceeds smoothly. This is because the spoke (S) in the incompletely inserted state changes its posture while being pulled in. When the spoke (S) is in the insufficiently inserted state, the thrust force along the axis of the spoke (S). Is pulled into place by
This is because the spokes (S) are easily lowered and rotated.

In the invention of each of the above claims, in the case where the driving device is pneumatic type, the driven spoke (S) is in a state in which the bent head (H) is almost in contact with the brim parts (10a) (10b). Since it is inserted deeply, the subsequent alignment process proceeds more smoothly.
