<2. Operation>
Next, operation | movement of the press system 1 of this Embodiment is demonstrated.

When the mold 8 to be used for the first time is installed in the press device 3, the guide system 41 allows the tip 100 a of the coil material 100 supplied from the coil material supply device 2 to be guided to the mold 8 in the press system 1. Are preset.
(2-1. Position setting operation)
After the mold 8 is attached to the press device 3, the operator operates the control device 9, whereby a command is transmitted from the overall control unit 5 to the supply device control unit 24, and the supply device control unit 24 performs the coil material supply device. The main body 20 is driven.

The supply device control unit 24 drives the uncoiler 21, the leveler 22, and the feeder 23 to send the tip 100 a of the coil material 100 from the discharge port 233 of the feeder 23 toward the press device 3.
Here, the operator sets the position of the guide portion 41 by teaching so that the tip 100a of the coil material 100 is fed between the guide member 72a and the guide member 72b of the end guide 72.

  Specifically, the electric motor 421 of the slide drive unit 42 and the electric motor of the rotation drive unit 43 are controlled to change the slide amount of the slide unit 52 and the rotation angle of the guide unit 41, as shown in FIG. The tip 100a of the coil material 100 supplied from the coil material supply device 2 is adjusted so as to be fed into the end guide 72 along the upper side of the first roller portion 11 and the second roller portion 14 of the guide portion 41. . FIG. 12 is a view showing a state in which the tip end 100 a of the coil material 100 is guided by the guide portion 41 and is fed into the end guide 72.

In this manner, the slide amount and the rotation angle at which the tip 100a of the coil material 100 is fed into the end guide 72 are obtained. The slide amount and the rotation angle are stored in the position storage unit 46 using, for example, an encoder value provided in the electric motor as position data.
Thus, the position data of the guide part 41 that can guide the tip 100a of the coil material 100 to the end guide 72 is stored as the guide position.

In order to provide versatility, a plurality of molds 8 having different shapes can be generally arranged in the press device 3. In different molds 8, the position of the lifter guide 71 is also different, so the position of the guide portion 41 that can guide the tip 100 a of the coil material 100 to the lifter guide 71 also changes.
For this reason, in the coil material guiding apparatus 4 according to the present embodiment, the position of the guide unit 41 is stored in the position storage unit 46 for each mold 8.

(2-2. Press operation)
Next, the pressing method of this embodiment will be described. FIG. 13 is a flowchart showing the pressing method of the present embodiment.
When the mold 8 and the coil material 100 are exchanged, the guide device control unit 45 recognizes the mold 8 arranged in the press device 3 by an operator's operation on the control device 9 and the like. Is acquired (step S5). Subsequently, the guide device control unit 45 takes out the position data of the guide unit 41 corresponding to the mold 8 from the position storage unit 46 (step S10).

Next, the guide device control unit 45 drives the slide drive unit 42 and the rotation drive unit 43 so as to control the guide unit 41 to a position corresponding to the mold 8 disposed in the press device 3 ( Step S20).
FIGS. 14A to 14C and FIGS. 15A to 15C are views for explaining the operation of the coil material guiding device 4.

First, as shown in FIG. 14A, the coil material guiding apparatus 4 is in a state in which the slide portion 52 is drawn into the rotating portion 51 and the rotating portion 51 is rotated downward. That is, the guide portion 41 is contracted and the end portion 41a of the guide portion 41 is lowered with the rotation axis O1 as a fulcrum. Such a position of the guide portion 41 is set as a retracted position.
Next, as shown in FIG. 14B, the guide device control unit 45 drives the rotation drive unit 43 to a value taken out from the position storage unit 46, so that the guide unit 41 has the end 41 a upward. Rotate to move.

Next, as shown in FIG. 14C, the guide device control unit 45 drives the slide unit 52 to the rotation unit 51 by driving the electric motor 421 of the slide drive unit 42 to the value taken out from the position storage unit 46. Slid toward the mold 8.
As a result, the end 41a of the guide 41 on the pressing device 3 side is positioned in the vicinity of the end guide 72 of the lower mold 7, and the movement of the guide 41 to the guide position is completed. As shown in FIG. 14C, the contact portion 83 of the transport portion 44 is not disposed between the sprocket 84d and the sprocket 84e (above the guide portion 41), and the sprocket 84a and the sprocket 84e It arrange | positions in between (upstream side of the guide part 41). Further, at the guide position shown in FIG. 14 (c), the guide portion 41 is disposed substantially horizontally. However, depending on the type of the lower mold 7, the end portion 41a is located above or below the FIG. 14 (c). In some cases, the guide portion 41 is inclined.

Next, in step S <b> 30, the overall control unit 5 transmits a command to the supply device control unit 24, and the supply device control unit 24 controls the coil material supply device main body 20 to change the coil material 100 that is wound. While being unwound, the coil material 100 is fed from the discharge port 233 of the feeder 23 to the coil material guiding device 4.
The leading end 100a of the coil material 100 supplied from the coil material supply device 2 is fed into the end guide 72 as shown in FIG. 15A while passing through the first roller portion 11 and the second roller portion 14. Since the rollers 112 and 142 of the first roller portion 11 and the second roller portion 14 described with reference to FIG. 3 rotate with the movement of the coil material 100, the coil material 100 is smoothly fed into the lifter guide 71. .

Here, after the exchange of the coil material 100 and the exchange of the mold 8, the operator operates the control device 9 to check the inside of the mold 8 in order to confirm whether the press working is normally performed. The coil material 100 is advanced so as to move by machining (hole drilling, drawing, bending, etc.).
When the operator operates the control device 9 to perform pressing first, the guide device control unit 45 moves the guide unit 41 to the retracted position in step S40 before performing the pressing operation. Specifically, as shown in FIG. 15B, the guide device control unit 45 controls the electric motor 421 of the slide drive unit 42 to contract the guide unit 41 and move the slide unit 52 from the inside of the press device main body 30. Evacuate.

Next, the guide device control unit 45 drives the electric motor (not shown) of the rotation drive unit 43 to rotate the rotation unit 51 downward as shown in FIG. Thereby, the guide part 41 moves to the retracted position.
Next, in step S50, the overall control unit 5 transmits a command to the press device control unit 38, and the press device control unit 38 drives the press drive unit 36 to move the slide 35 up and down. As a result, pressing is performed on the coil material 100 guided to the pressing device 3.

  FIG. 16A and FIG. 16B are schematic diagrams for explaining the vertical movement of the coil material 100 during press working. FIG. 16A and FIG. 16B show the upper mold 6 and the lower mold 7. The mold 8 shown in FIG. 16A shows a portion for drilling and a portion for bending after drilling. The structure of the mold 8 shown in FIG. 16A will be described in order. In the lower mold 7, the lifter guide 71 is divided and is shown as 711 and 712 in the drawing. A spring member 713 is provided below each of the lifter guides 711 and 712 to urge the lifter guides 711 and 712 upward. A drilling portion 61 is formed on the downstream side of the lifter guide 711 of the upper mold 6. A spring member 611 is provided on the upper side of the drilling portion 61. A bending portion 62 is formed on the downstream side of the drilling portion 61 of the upper mold 6. A pressing portion 63 is provided on the downstream side of the bending portion 62, and a spring member 631 is provided on the upper side of the pressing portion 63.

A bent portion 73 is formed in the lower mold 7 so as to face the bent portion 62 of the upper mold 6. The lifter guide 712 is provided on the downstream side of the bending portion 73.
When the press device control unit 38 lowers the slide 35, the upper die 6 is lowered as shown in FIGS. 16 (a) and 16 (b), and between the upper die 6 and the lower die 7. The coil material 100 is sandwiched and press working is performed. At the time of press working, as shown in FIG. 16B, the lifter guides 711 and 712 move downward, so that the coil material 100 also moves downward. Therefore, a portion (indicated as 100c in the drawing) closer to the coil material supply device 2 than the lower mold 7 of the coil material 100 is pulled downward. In order to prevent excessive tension from being applied to the coil material 100 during press working by being pulled in this way, the coil material guide device 4 of the present embodiment moves the tip 100a of the coil material 100 to the lifter guide 71 (711, 711, After guiding to 712), the guide portion 41 is moved to the retracted position (see FIG. 15C).

In the coil material supply device 2, the roller 231 is separated from the coil material 100 in accordance with the lowering timing of the slide 35, thereby preventing excessive tension from being applied to the coil material 100.
Thereafter, the coil material is sequentially supplied from the coil material supply device 2 and is pressed by the press device 3.
Subsequently, the press working is sequentially performed, and the end detection unit 236 detects that the coil material 100 wound as shown in FIG. 17A disappears and the end 100b passes the roller 231 of the feeder 23. (Step S <b> 60), the supply device control unit 24 transmits the detection result to the overall control unit 5.

The overall control unit 5 stops the press device 3 and gives an instruction to the guide device control unit 45. The guide device control unit 45 moves the guide unit 41 from the retracted position to the guide position as shown in FIG. (Step S70).
Next, as shown by an arrow B in FIG. 17B, the guide device control unit 45 drives the chain driving motor 82 to rotate the chain 81. Due to the rotation of the chain 81, the abutting portion 83 moves toward the downstream side while passing through the upper side of the guide portion 41, and abuts against the terminal end 100b as shown in FIG. Furthermore, when the contact portion 83 moves downstream (see arrow C), the terminal end 100b is pushed toward the lower mold 7 and the coil material 100 is conveyed toward the lower mold 7 (step S80). ).

The overall control unit 5 operates the press device 3 in accordance with the conveyance of the coil material 100 by the abutting unit 83 to perform press working (step S90).
Then, as shown in FIG. 18B, steps S80 and S90 are repeated until the contact portion 83 moves to the end 41a of the guide portion 41 on the press device side (step S100). When the contact portion 83 reaches the end portion 41a of the guide portion 41, the guide device control portion 45 moves the guide portion 41 from the guide position to the retracted position (step S110), and the control ends. The arrival of the abutment portion 83 at the end portion 41a of the guide portion 41 can be detected from the encoder of the chain drive motor 82.

In addition, when performing a press work in step S90, you may move the guide part 41 to a retracted position.

When the first mold 8 is used, the position of the guide portion 1041 is set in advance so that the tip 100 a of the coil material 100 supplied from the coil material supply device 2 can be guided to the mold 8 in the press system 1. The

(2-1. Position setting operation)
After the mold 8 is attached to the press device 3, the operator operates the control device 9, whereby a command is transmitted from the overall control unit 5 to the supply device control unit 24, and the supply device control unit 24 performs the coil material supply device. The main body 20 is driven.
The uncoiler 21, the leveler 22, and the feeder 23 are driven to feed the tip 100 a of the coil material 100 from the discharge port 233 of the feeder 23 toward the press device 3.

Here, the operator sets the position of the guide portion 1041 by teaching so that the leading end 100a of the coil material 100 is fed between the guide member 72a and the guide member 72b of the end guide 72.
Specifically, the coil material supplied from the coil material supply device 2 as shown in FIG. 23 while changing the position of the piston 1421b in the first hydraulic cylinder 1421 and the position of the piston 1422b in the second hydraulic cylinder 1422. Adjustment is performed so that the tip 100 a of 100 is fed into the end guide 72 along the upper side of the guide portion 1041. FIG. 23 is a view showing a state in which the leading end 100 a of the coil material 100 is guided by the guide portion 1041 and sent to the end guide 72.

In this way, the position of the piston 1421b (also referred to as the position of the piston rod 1421c) in the first hydraulic cylinder 1421 where the tip 100a of the coil material 100 is fed into the end guide 72 and the position of the piston 1422b (piston in the second hydraulic cylinder 1422). The position of the rod 1422c).
The obtained positions of the pistons 1421b and 1422b are stored in the position storage unit 46.

In this way, the position of the guide portion 1041 that can guide the tip 100a of the coil material 100 to the end guide 72 is stored as the guide position.
In order to provide versatility, a plurality of molds 8 having different shapes can be generally arranged in the press device 3. In different molds 8, the position of the lifter guide 71 is also different, so the position of the guide portion 1041 that can guide the tip 100 a of the coil material 100 to the lifter guide 71 also changes.

For this reason, in the coil material guiding apparatus 1004 of the present embodiment, the positions of the pistons 1421b and 1422b are stored in the position storage unit 46 as position data for each mold 8.
(2-2. Press operation)
Next, the pressing method of this embodiment will be described. FIG. 24 is a flowchart showing the pressing method of the present embodiment.

  When the mold 8 and the coil material 100 are exchanged, the guide device control unit 45 recognizes the mold 8 arranged in the press device 3 by an operator's operation on the control device 9 and the like. Is acquired (step S5). Subsequently, the guide device control unit 45 takes out the position data of the pistons 1421b and 1422b corresponding to the mold 8 from the position storage unit 46 (step S10).

Next, the guide device control unit 45 controls the pump 1091, the first servo valves 1093 a, 1094 a, the second servo valves 1093 b, 1094 b, and the piston 1421 b of the first hydraulic cylinder 1421 and the piston 1422 b of the second hydraulic cylinder 1422. Is set to a position corresponding to the mold 8 arranged in the press device 3 (step S20).
FIGS. 25A to 25C and FIGS. 26A to 26C are views for explaining the operation of the coil material guiding apparatus 1004. FIG.

  First, as shown in FIG. 25 (a), the coil material guiding apparatus 1004 has a state in which the second guide member 1412 is drawn below the first guide member 1411 and the first guide member 1411 is rotated downward. It has become. That is, the guide portion 1041 is contracted, and the roller portion 1413 is lowered with the rotation axis O1 as a fulcrum. Such a position of the guide portion 1041 is a retracted position, and the first hydraulic cylinder 1421 and the second hydraulic cylinder 1422 are both contracted.

Next, as shown in FIG. 25 (b), the guide device control unit 45 guides the roller unit 1413 to move upward by extending the first hydraulic cylinder 1421 to the value extracted from the position storage unit 46. The part 1041 is rotated.
Next, as shown in FIG. 25C, the guide device control unit 45 extends the second hydraulic cylinder 1422 to a value taken out from the position storage unit 46, thereby moving the second guide member 1412 to the first guide member 1411. Slid toward the mold 8.

As a result, the roller portion 1413 that is the end of the guide portion 1041 on the pressing device 3 side is positioned in the vicinity of the end guide 72 of the lower mold 7, and the movement of the guide portion 1041 to the guide position is completed.
Next, in step S <b> 30, the overall control unit 5 transmits a command to the supply device control unit 24, and the supply device control unit 24 controls the coil material supply device main body 20 to change the coil material 100 that is wound. While unwinding, it is fed from the discharge port 233 of the feeder 23 to the coil material guiding device 1004.

  The leading end 100a of the coil material 100 supplied from the coil material supply device 2 travels through the first guide member 1411, the second guide member 1412, and the roller portion 1413 to the end guide 72 as shown in FIG. It is sent. Since the roller portion 1413 rotates with the movement of the coil material 100, the coil material 100 is smoothly fed into the lifter guide 71.

Here, after the exchange of the coil material 100 and the exchange of the mold 8, the operator operates the control device 9 to check the inside of the mold 8 in order to confirm whether the press working is normally performed. The coil material 100 is advanced so as to move by machining (hole drilling, drawing, bending, etc.).
When the operator first operates the control device 9 to perform pressing, the guiding device control unit 45 moves the guiding unit 1041 to the retracted position in step S40 before performing the pressing operation. Specifically, the guide device control unit 45 controls the hydraulic unit 1090 and contracts the second hydraulic cylinder 1422 so that the second guide member 1412 is moved under the first guide member 1411 as shown in FIG. Evacuate to the side. Next, the guide device control unit 45 controls the hydraulic unit 1090 to contract the first hydraulic cylinder 1421, thereby rotating the first guide member 1411 downward as shown in FIG. As a result, the guide unit 1041 moves to the retracted position.

Next, in step S50, the overall control unit 5 transmits a command to the press device control unit 38, and the press device control unit 38 drives the press drive unit 36 to move the slide 35 up and down. As a result, pressing is performed on the coil material 100 guided to the pressing device 3.
Thereafter, the coil material is sequentially supplied from the coil material supply device 2 and is pressed by the press device 3.

<Features>
(1)
As shown in FIGS. 3 and 19, the coil material guiding devices 4 and 1004 of the present embodiment press the coil material supply device 2 that supplies the coil material 100 and the coil material 100 that is supplied from the coil material supply device 2. The coil material guiding device is disposed between the press device 3 to be processed and includes guide units 41 and 1041 and a guide device control unit 45 (an example of a control unit). The guide portions 41 and 1041 guide the tip 100 a of the coil material 100 supplied from the coil material supply device 2 to the mold 8 disposed in the press device 3. As shown in FIGS. 14 (a) to 14 (c) and FIGS. 25 (a) to 25 (c), the guide device control unit 45 is based on the mold 8 disposed in the press device 3. The positions of the guide portions 41 and 1041 are controlled so as to guide 100a to the mold 8.

Thus, the coil material guide devices 4 and 1004 are arranged between the coil material supply device 2 and the press device 3, and the guide portion 41 so as to guide the tip 100 a of the coil material 100 to the mold 8 of the press device 3. , 1041 are controlled.
For this reason, when the coil material 100 is supplied from the coil material supply device 2, the leading end 100a of the coil material 100 is automatically guided to the mold 8 disposed in the press device 3 by the guide portions 41 and 1041. It is not necessary for a person to enter the press device 3, and the setup time when replacing the coil material 100 or the mold 8 can be shortened.

It should be noted that the control of the positions of the guide units 41 and 1041 in this specification includes control of the posture by turning and / or changing the inclination of the guide units 41 and 1041.
(2)
In the coil material guiding devices 4 and 1004 of the present embodiment, the guide portions 41 and 1041 are arranged as shown in FIGS. 14 (c), 15 (a), 25 (c), and 26 (a). When the leading end 100a of the material 100 is guided to the mold 8 of the press device 3, the coil material 100 is supported from below. The coil material guiding devices 4 and 1004 further include driving units 47 and 1042. The drive units 47 and 1042 move the end portions 41a and 1041a (an example of the first end portion) of the guide portions 41 and 1041 in the vertical direction. The guide device control unit 45 controls the positions of the guide units 41 and 1041 by controlling the drive units 47 and 1042.

  Thus, by controlling the vertical positions of the end portions 41 a and 1041 a on the pressing device 3 side of the guide portions 41 and 1041, the roller portion 1413 (an example of an end portion) of the guiding portion 1041 is arranged in the pressing device 3. It can be adjusted to the height of the mold 8 (in particular, the lifter guide 71 of the lower mold 7). Thereby, the front end 100a of the coil material 100 supplied from the coil material supply device 2 can be guided to the mold 8 while being supported from below by the guide portions 41 and 1041.

(3)
In the coil material guiding devices 4 and 1004 of the present embodiment, the guide portions 41 and 1041 are provided at the tip of the coil material 100 as shown in FIGS. 15 (a) to 15 (c) and FIGS. When guiding 100a to the mold 8, it is possible to move between a guide position for supporting the coil material 100 from below and a retracted position retracted from the guide position. The drive units 47 and 1042 move the guide units 41 and 1041 between the guide position and the retracted position.

The coil material 100 guided to the mold 8 disposed in the press apparatus 3 is disposed in the lifter guide 71 of the mold 8, and at the time of pressing, as shown in FIGS. As the lifter guide 71 sinks, the coil material 100 also moves downward.
For this reason, in the state where the guide portions 41 and 1041 are arranged at the guide position at the time of press processing, the press processing of the coil material 100 may be affected, but the guide portions 41 and 1041 are located between the guide position and the retracted position. Since it can move, it can prevent affecting the coil material 100 at the time of press work by moving the guide parts 41 and 1041 to the retracted position at the time of press work.

(4)
The coil material guiding devices 4 and 1004 of the present embodiment further include a position storage unit 46 (an example of a storage unit). The position storage unit 46 stores a guide position for each mold 8 arranged in the press device 3. The guide device control unit 45 (an example of a control unit) controls the drive units 47 and 1042 to place the guide units 41 and 1041 at guide positions corresponding to the molds 8 arranged in the press device 3.

The guide positions of the guide portions 41 and 1041 are determined in advance for each mold 8 by teaching and stored in the position storage section 46, so that the guide sections 41 and 1041 reach the guide position corresponding to the mold 8 disposed in the press device 3. Can be moved automatically.
Thereby, the guide parts 41 and 1041 can be positioned at a guide position suitable for each mold 8.

Teaching may be performed at the time of trial hitting using the mold 8.
(5)
In the coil material guiding devices 4 and 1004 of the present embodiment, the guide portions 41 and 1041 can expand and contract toward the mold 8 disposed in the press device 3. The drive parts 47 and 1042 extend the guide parts 41 and 1041 to move the end parts 41 a and 1041 a (an example of the first end part) of the guide parts 41 and 1041 toward the mold 8.

As a result, even when the mold 8 is not disposed at the end of the press device 3, the guide portions 41 and 1041 can be extended to the vicinity of the mold 8, so that the coil material 100 can be guided to the mold 8.
(6)
In the coil material guiding devices 4 and 1004 of the present embodiment, as shown in FIGS. 6 to 8 and FIGS. 25 (a) and 25 (b), the guide portions 41 and 1041 are end portions 41a and 1041a (first end).
