Description

Detailed Description of the Invention Technical Field The present invention relates to a method and device for automatically regulating a material in a winding machine for, for example, a rod-like material, and more particularly, it relates to a method and device for automatically regulating a material in a winding machine for forming a rod-like material ( Mainly metal materials)
For example, in a winding machine that forms (manufactures) a helical product by winding a series of coil springs, it automatically corrects twisting (twisting in the circumferential direction), especially at the end of the material during the winding process. This invention relates to an automatic regulation method and device for exposing and regulating control.

Technical Background In this type of machine that winds and forms a wire material into a spiral shape, such as a coil spring manufacturing machine, the material is generally fed horizontally from the feeder side to the right machine side.

After the tip of the material is fixed (chucked) at the starting end of the core in the winding machine, the material is wound around the outer periphery of the core at a predetermined pitch based on the rotation of the core and the relative movement between the core and the material. It is wound in a continuous spiral at an angle. When the material is spirally wound in this way, a "twist" that is affected by the pitch, angle, etc. occurs in each turn of the element (A), and this is continuously increased cumulatively during the winding process. , at the end of winding, there is quite a big "
This appears as twisting, and in some cases, "twisting" with unpredictable errors that differ from theoretically calculated values may occur. By the way, the value of ``twist'' varies greatly depending on the size of the material and the same conditions, such as length, wire diameter, winding pitch and angle.

Therefore, in such winding forming, controlling the twist of the material is one of the important issues, especially when winding the terminal part of the moon under the set conditions, in other words, the terminal part at the end of winding. When you want to ensure that the direction of the part is in a predetermined position and angle, it is impossible to leave the double twist
mit'l, some proper twist control is rather absolutely required. For example, when forming a coil spring with a seat part, a blank 4J is used which has a wedge-shaped rolled part corresponding to the seat part in advance at the tip and end part.When this material is spirally wound, the tip rolling part In the rolling section, there is no problem because the core metal is held in a predetermined position and orientation when chucked, but in the terminal rolling section, the core metal is simply wound around the outer periphery of the core metal and there is no problem. It will no longer be regulated. Therefore, in order to obtain a high-quality spring with an accurate and stable shape, it is most desirable and necessary to ensure that the rolled end portion is in a predetermined position and orientation.

Furthermore, the necessity of the above-mentioned torsion regulation is questioned not only during cold manufacturing of the 11111, but especially during hot manufacturing. In other words, in the manufacturing of coil springs, in the case of small springs made of relatively thin (small wire diameter) coil springs, low-temperature coil springs are generally used as the cold form, while thick (large wire diameter) coil springs are used. ) In the case of large springs whose material is J:, use an element +1 that has been heated in advance to a predetermined high temperature in a furnace as a hot form, and wind each material with a core metal at a predetermined pitch. ing. ” 1. In cold working, if no consideration is given to improving operability and productivity, manual work (multiple workers working in coordination with each other using appropriate equipment) is required, relying on intuition of the name of the work. It is possible to control twisting to a certain extent even when the work is carried out (in some cases), and some people actually do this.

However, such manual work in hot manufacturing is too dangerous, with frequent heat loss accidents, and the problem is so urgent that there is a trend that these dangerous operations should be abolished. Appropriate technology for torsion control is strongly desired. However, none of the conventional techniques can meet the above-mentioned sagging regulation, and effective countermeasures have been awaited.

Purpose The present invention has been newly proposed in view of the above-mentioned technical background. The material is configured to automatically control twisting at an appropriate angle for the remaining unwound portion of the material from the time when a predetermined total rotation angle is reached to the time when winding is completed. This is an automatic regulating method and its device, and its purpose is to provide appropriate twist regulation by fully considering the size of the material and the winding line (I), and to prevent "twisting" from being unregulated and large. The purpose is to suppress the end portion where this occurs easily within the allowable helix angle range and ensure that the same portion is in the specified orientation and angle.This allows efficient production of high-quality products with accurate and stable shapes (molding). ) is to do.

By the way, the same restriction tool 60
is moved to the regulating position 1 in time with the feeding of the material, and immediately returned to the rest position after regulating.

In addition, the cylinder 62 mentioned in "1" is the support base 26Lt! It is attached to the i side, and one end of the rod 63'' is connected to the arm 64 at the rear end of the rotation shaft 58. Reference numeral 65 denotes a detector for confirming the position switching of the restrictor 60, and is provided opposite to the position operated by the arm 64.

The optical spacing device 66 is for pre-curving the tip of the material in the winding direction so that it can come into close contact with the outer periphery of the core M after regulating the tip of the material, as shown in Fig. 12.13. A supporting frame 6 is installed at the same location as the restricting tool 60 of the aforementioned tip restricting device 56 and is fixed to the front end of the lifting platform 10.

Therefore, even if the moving table 92 is moved forward over a predetermined stroke, after the tip of the material is locked at the chuck position on the core metal M side, slipping occurs between the clamp W and the clamp J4 + lOO. It is now possible to finish the feeding and prevent the material from being deformed by stopping the forced feeding.

The terminal regulating device 104 of this example is installed at the stimulation site of the first feeding device 25 described above. This device 104 is designed to control the orientation of the remaining portion of the material, especially the end rolled portion W2, at a predetermined point in the winding process, which is also referred to as "end-raising", to correct its twist. 2 Section 1.1

Regarding 'torsion', the target value was determined in advance based on the size and winding conditions of the target spring, and various experimental data were added to this. Even if it is assumed that the helix angle γ per unit length (per winding angle) of the remaining portion 1. changes linearly, there is almost no error and there is virtually no problem within the allowable value range (No. (See Figure 43).

The coil spring manufacturing machine of this example is configured to move to the right side of Fig. 1).The coil spring manufacturing machine of this example is constructed by cooperation between each device on the feeder F side and each device on the one-winding machine C side configured as described above. 1) Based on the form of cycle 1 molding, a series of operating steps from feeding the material to winding can be performed fully automatically.As an example, the manufacturing example of a spring S with seats at both ends shown in Fig. 41 is based on the operation of each device. The steps will be explained in order. First, on the feeder F side, the lifting platform 10 of the machine platform 1 moves forward and backward relative to the fixed base 2 by the operation of the motor 4 and cylinder 13, depending on the length and winding direction of the material W.・By operating the cellar 1 downward and holding it at a predetermined position and tilted height, all the devices are moved to the predetermined position in the cellar 1, which raises the predetermined position toward the forward direction (core metal side). supply line is set up.

Under this, the first. The second feeding device @ 1 B, 25 and the attitude holding device 40 are operated in synchronism. That is, in the first feeding device 18, the material W taken out from the heating furnace H by the worker is received between the rollers 24 and constantly fed in a horizontal manner. The orientation of the rolling part Q+ is roughly adjusted. ), then the posture holding device 40 and the receiver 1. 4 is held between the J roller 46 and the presser roller 50, and the 4 is rested against the vibration A while the direction in the circumferential direction is determined.1. +i while correcting the direction of the rolled end portion νJ1. Then, the second feeding device 25 holds the material between the rollers 29 and feeds it forward toward the tip regulating device 5G in the I)'lJ direction (Fig. 1(a)). reference).

In the tip regulating device 56, the regulating tool 60 is moved to the regulating position on the supply line by forward movement of the cylinder 62 in synchronization with the feeding timing of the material, and the regulating port 61 controls the direction of the tip rolling part W1, After regulating the position, the cylinder 62
By the return movement of , the restrictor 60 is retracted to the rest position above the line and stands by until the next 1st movement. At the end of the regulating operation, the tip bending device 66 is activated at key 11. After the same device (in 3G, one cylinder 69.78 works together), both arms 73 are moved to one forming position, and the tip of the material is bent in a predetermined direction with the second clamp knife 17G.
Both arms 73 are promptly retracted to the rest position and are on standby until the next operation.

In addition, in the second feeding device 25, before the material is fed into the feeding device 91 (after the material is clamped), each roller 87 is retracted all at once out of the supply line by the return movement of the cylinder 88. Prior to the feeding of step 4, step 13 returns to the feeding position.

In addition, in the feeding device 191, when the movable table 92 reaches the forward end, the feeding is finished. By the backward movements of '-94 and 101, the arm 1199 is released and returns to the backward end together with the movable table 92.

In response to the operation of the second moving and holding devices 157 and 166, the -C core metal M is operated to wind the element [71]. In other words, the core metal h=f′ of i! .

In the dynamic mode, the chuck mechanism 166Δ of the second movable holding device A 16 (5) goes around in the winding direction of the moon and the chuck J (4 is waiting at a predetermined position below the core metal M. The forward movement of the cylinder 180 causes the operating rod 179.

The connecting main 11111 G 3 is rotated through the Tairaichi train 164. By synchronizing the forward movement of 160 and the stop rotation 1j14 movement of the motor 170, both moving bodies 15B and 1G7 move forward along the rail 159°168 at the same speed and at the same speed.
, the core metal M is formed into a spring by the cooperation of each device mentioned above.
[Control operation is performed in accordance with ko-roi'1.

Here, regarding the control of the core metal M, "E" will be described. That is, as shown in Fig. 41, after the spring S, the seats s+ and SI at both ends

Then, when the terminal is restricted as described above, the detector 127 in the detection confirmation-I-4 stage performs confirmation detection (ON), thereby controlling and driving each of the motors 109418. The Zunawaji motor 118 is driven at a slow speed by an angle of 7 minutes to accommodate the "twist" that occurs by the time the winding of the remaining material 128 is completed.
On the other hand, the motor 109 is driven at a speed that matches the winding speed (circumferential speed) of the core metal M. As a result, the regulating tool 122
To restrict the torsion of the moon, the terminal rolled part W is slowly rotated in accordance with the appropriate torsion angle γ while being engaged and held, and the material is extruded in accordance with the winding speed of the core metal M (No. 43
(see figure).

Incidentally, such torsion regulation is substantially started at the time of detection by the detector 127 (a), that is, at the time of the rotation angle T8 of the through tγ winding of the core metal M, and by the restriction tool 122 located at the forward end.

In synchronization with the above-mentioned terminal regulating operation, the core metal M is controlled to the normal operating state on the stone grain (mud) side, that is, the regulating device 122 starts regulating at 11'JT+ (predetermined total rotation angle). At the same point in time (N, Accordingly, the core metal N1 is rotated and moved at a predetermined same speed and winds the remaining portion 11 of the nut 3H, which is regulated by the screw 4 as described above.

As a result, the submergence control J(, I22) is returned to the reverse rest position and is put on standby until the next operation.

On the other hand, at the end stage of the winding operation, the terminal fixing device 200 is activated. In the Zunawaji device 200, cylinder 2
