Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a waste material processing method for processing waste material generated from a long material cutting device that sequentially cuts a long material such as a steel strip into a predetermined length, and a waste material processing device used for carrying out the method. is there.
[0002]
[Prior art]
When a specific product is manufactured by laminating or forming a strip-shaped material plate, a material roll made of a strip-shaped long material wound in a coil shape is prepared, and the material A long material unwound from a roll is supplied to a shear, and a raw material plate obtained by cutting the material into a predetermined cutting length by the shear is sequentially supplied to a processing apparatus.
[0003]
Also, when it is necessary to use multiple types of material plates with different width dimensions and materials, prepare multiple material rolls wound with different types of long materials, and rewind them from each roll. To the shear.
[0004]
For example, when manufacturing a wound core for a transformer, prepare multiple types of steel strips (long materials) with different width dimensions in order to increase the space factor of the core by making the cross-sectional shape of the core close to a circle. A plurality of types of laminates having different width dimensions are formed by winding a steel plate (material plate) obtained by cutting each steel strip until a predetermined thickness is obtained, and the plurality of types of laminates are laminated. By doing so, an iron core having a stepped contour is formed.
[0005]
As described above, when the raw material plates are sequentially supplied to the processing apparatus and processed, it is necessary to incorporate a long material cutting device capable of continuously forming the raw material plate into the processing apparatus. Usually, this type of cutting device cuts the uncoiler that rewinds the long material from the material roll, the feeder that feeds the long material that has been unwound by the uncoiler, and the long material that is fed by the feeder. And a shear for forming a strip-shaped material plate.
[0006]
The uncoiler includes an uncoiled shaft that is rotatably supported, a roll holding mechanism that is attached to the uncoiled shaft, and a drive mechanism that rotates the uncoiled shaft, and is a material that is held on the uncoiled shaft via the roll holding mechanism. The long material is rewound from the material roll by rotating the roll.
[0007]
When using multiple types of long materials with different width dimensions, materials, etc., it is cumbersome to replace the material roll for each different material type, so the uncoiled shaft can be positioned at the material delivery position. It is preferable to use a plurality of uncoilers, each of which has a plurality of slabs, so that a material roll can be mounted on each uncoil shaft.
[0008]
In addition, in order to prevent the time required for material roll replacement from becoming the operation stop time and improve the production efficiency, even if only one type of long material is used, multiple uncoilers are used. It is preferable to use it. The present applicant has previously proposed a multiple uncoiler used in Japanese Patent Application No. 6-117080 (Japanese Patent Laid-Open No. 7-315639) for rewinding a long material. This multiple uncoiler is provided with a plurality of uncoiled shafts that are rotated around an axis extending in the vertical direction while holding a material roll wound with a long material and positioned at a material delivery position. The long material is rewound from the material roll mounted on the uncoil shaft by rotating the uncoil shaft positioned at a position in the material rewind direction.
[0009]
[Problems to be solved by the invention]
As described above, in the long material cutting device that sequentially cuts the long material unwound from the uncoiler by the shear, all the long material wound around the material roll is rewound to constitute the material roll After the tail end of the long material (the final end of the long material) is separated from the uncoiler (after the material is cut), the material that does not reach the predetermined cutting length remains held in the feeder. .
[0010]
The material remaining in the feeder without reaching the cutting length needs to be disposed of as waste material.However, conventionally, when the waste material is generated, the operation of the cutting device is stopped and the waste material is removed from the feeder. Since the operation is performed manually, it is inevitable that the operation takes time, and there is a problem that the operation stoppage time required for performing the operation of removing the waste becomes long and the work efficiency is lowered.
[0011]
An object of the present invention is to provide a waste material processing method for a long material cutting apparatus capable of shortening the operation stop time generated when removing the waste material, and a waste material processing apparatus used for carrying out the method. There is.
[0012]
[Means for Solving the Problems]
The present invention has a plurality of uncoiled shafts which are pivoted around an axis extending in the vertical direction while holding a material roll wound with a long material and positioned at the material delivery position, and are positioned at the material delivery position. An uncoiler that rewinds a long material from a material roll attached to the uncoil shaft by rotating the uncoiled shaft that is unwound in the material rewind direction, a feeder that feeds the long material unwound by the uncoiler, and a feeder The present invention relates to a method for treating a waste material generated when a material shortage occurs in a long material cutting apparatus including a shear that cuts a long material fed by a predetermined cutting length.
[0013]
In the present invention, the waste material discharge position is set at a position away from the material delivery position of the uncoiler by a predetermined angle in the turning direction of the uncoil shaft, and the tail end of the long material fed by the feeder is separated from the uncoiler. When it is detected that the length of the long material held in the feeder has become equal to or less than the set length after being detached, the feeding direction of the feeder is reversed and held in the feeder. The long material is sent back to the uncoiler as waste. Then, when the tip of the waste material being fed back facing the shear side reaches the set position set near the feeder, the feeder is stopped, and the waste material protruding from the feeder to the uncoiler side is provided on the uncoiler side The waste material is detached from the feeder by clamping with a tool and moving the clamp tool in a direction away from the feeder.
[0014]
After that, the uncoil shaft at the material delivery position is moved from the material delivery position to the waste material discharge position together with the clamp that clamps the waste material, and the uncoil shaft equipped with a new material roll is moved toward the material delivery position. In this way, the uncoiler is caused to rotate the uncoiled shaft. The clamp that clamps the waste material is unclamped at the waste material discharge position to discharge the waste material.
[0015]
When waste material is processed in this way, waste material can be easily removed from the feeder by the reverse feeding operation of the feeder and the movement of the clamp tool. Time can be shortened, and work efficiency can be improved.
[0016]
As the uncoiler, a plurality of uncoiled shafts provided so as to be able to turn around an axis extending in the vertical direction while holding a material roll that is radially arranged along a horizontal plane and wound with a long material, and Clamping tools that are provided so as to correspond to a plurality of uncoiled shafts and clamp a long material unwound from a material roll held on the corresponding clamp shafts from above and below, and the corresponding uncoiled shafts of the uncoiled shafts. A plurality of material delivery devices that have a clamp tool moving mechanism that reciprocally displaces in a direction perpendicular to the axis, and that is provided to turn together with the uncoil shaft; and a plurality of uncoil shafts and a plurality of material delivery devices that swivel The rotation drive mechanism for positioning at the material delivery position and the uncoiled shaft positioned at the material delivery position rotating in the material unwinding direction. An uncoiled shaft drive mechanism, and forwards the long material unwound from the material roll mounted on the uncoiled shaft at the material delivery position through the clamp of the material delivery device corresponding to the uncoiled shaft. It is preferable to use what was made.
[0017]
When such an uncoiler is used, the waste material processing apparatus according to the present invention is used when the tail end of the long material fed by the feeder passes the judgment position set in the vicinity of the feeder inlet after being detached from the uncoiler. A tail end detection device for detecting the tail end of the long material and outputting a tail end detection signal; and a tail end of the material held in the feeder after the tail end detection device outputs the tail end detection signal. By switching the feeding direction of the feeder before reaching the inlet of the feeder, the material is reversely fed as waste material, and the tip of the reversely fed waste material facing the shear side is between the feeder and the shear and close to the feeder Feeder control means for controlling the feeder to stop the feeder when the set position set in the position is reached, and the reversely fed feeder Clamp tool controlling means for clamping the waste material protruding toward the uncoiled side by the clamp tool of the material delivery device at the material delivery position, and moving the clamp tool clamping the waste material away from the feeder. A clamp tool moving mechanism control means for controlling the clamp tool moving mechanism so as to cause the scrap material to be released from the feeder, and a clamp tool that clamps the waste material after confirming that the scrap material has been released from the feeder. A turning drive mechanism control means for controlling the turning drive mechanism to move the uncoiled shaft holding the new material roll to the material delivery position while moving the waste material toward the waste material discharge position set at a position away from the material delivery position. When the clamp that clamps the waste material reaches the waste material discharge position, The clamp fixtures are then amplifier can be constituted by a waste discharge clamp releasing means for controlling to the unclamped state.
[0018]
In the present invention, after the tail end detection device outputs the tail end detection signal, before the tail end of the material held in the feeder reaches the inlet of the feeder (before the material can not be fed backward). ) The feeding direction of the feeder may be switched. Therefore, the timing of switching the feeding direction of the feeder may be at the time when the tail end detection signal is generated, or even when the material fed by the feeder is determined to be waste after the tail end detection signal is generated. Good.
[0019]
Whether the material being fed by the feeder is waste or not is determined by the feed length of the material by the feeder at the time when the tail end detection signal is generated (the feeder was fed after the previous cutting was performed) The difference between the material length) and the required cutting length can be made by comparing the distance between the determination position and the feeder inlet.
[0020]
That is, the difference between the feed length of the material by the feeder at the time when the tail end detection signal is generated (the length of the material fed by the feeder after the previous cutting is performed) and the necessary cutting length is the judgment position. When the distance to the feeder inlet is longer, the tail end detection signal is generated because the material currently held in the feeder is insufficient when the tail end detection signal is generated. At that time, it can be determined that the material is waste.
[0021]
The tail end detection signal is generated when the difference between the feed length of the material by the feeder at the time the tail end detection signal is generated and the required cutting length is shorter than the distance between the judgment position and the feeder inlet. After that, when the feeding of the material for the necessary cutting length is completed, it can be determined that the material held at that time in the feeder is a waste material.
[0022]
Strictly speaking, the tail end detection signal alone cannot detect that the material length is insufficient as described above. However, if the judgment position is set sufficiently close to the feeder inlet, the tail end is set for convenience. Regardless of the feed length of the material by the feeder at the time when the detection signal is generated, the material held in the feeder immediately after the tail end detection signal is generated is determined to be waste material, and the tail end is determined. The feeding direction by the feeder may be reversed immediately after the detection signal is generated. In the case of such a configuration, the amount of material discarded as waste material is somewhat increased, but it is not necessary to perform troublesome calculation when detecting the occurrence of waste material, so that control can be simplified.
[0023]
As described above, the tail end of the long material is detected at the judgment position set near the feeder inlet, and the tail end of the material fed by the feeder is detected at the feeder inlet after the tail end is detected. If the feeding direction of the feeder is reversed before it reaches, the waste material can be automatically returned to the uncoiler side.
[0024]
Also, as described above, when the tip of the waste material that has been fed back facing the shear side reaches the set position that is set near the feeder (before the fed material is removed from the feeder), the feeder is fed. When the material is clamped by the uncoiled clamping tool after being stopped, the waste material can be held by the clamping tool without being dropped and transferred to the waste material discharge position side.
[0025]
It is preferable to provide a waste material forming apparatus for forming the waste material, which has been moved to the waste material discharge position, in a coil shape by sandwiching it between a plurality of forming rollers.
[0026]
If such a molding apparatus is provided, the waste material can be molded into a compact shape, so that the waste material can be easily treated.
[0027]
In order to automatically perform the operation of forming the waste material that has been moved to the waste material discharge position into a coil shape, the waste material that has been detached from the clamp tool when the clamp tool that clamps the waste material is placed in an unclamped state is discarded. It is preferable to provide a conveying device that conveys between the molding rollers of the molding device. In this case, activation of the waste material forming device may be performed when it is detected that the transport device transports the waste material, or may be performed at an appropriate timing before the transport device transports the waste material. . For example, the waste material forming apparatus may be activated when it is detected that the clamp tool has reached the waste material discharge position.
[0028]
In addition, the waste material forming device is placed in front of the clamp tool moved to the waste material discharge position, and when the clamp tool that clamps the waste material reaches the waste material discharge position, the clamp tool is formed into the waste material. A waste material loading operation in which the tip of the waste material clamped by the clamp tool by being advanced to the apparatus side is loaded into the waste material molding apparatus, and a clamp release operation for bringing the clamp tool into an unclamped state when the waste material loading operation is completed The waste material loading clamp control means for controlling the clamp tool moving mechanism and the clamp tool so as to perform the operation, and when it is confirmed that the waste material loading clamp control means has put the clamp tool in an unclamped state, The waste material forming operation can also be automatically performed by providing the waste material forming apparatus starting means that starts and performs the waste material forming operation.

As shown in FIGS. 1 and 2, the long material is unwound and cut from the material roll 20 held by the uncoiled shaft 14A positioned at the material delivery position (position for delivering the material toward the feeder 2). When the pressure roller 2d of the feeder 2 is separated from the feed roller 2b and the pinch is released, the piston rod of the fluid pressure cylinder 30A is extended to move the clamp tool holding frame 32A to the forward position (FIG. 1 and FIG. 1). The tip 3a of the long material 3 protruding from the clamp 36 is inserted between the feeding roller 2b and the pressure roller 2d of the feeder 2 by moving forward to the position indicated by the chain line in FIG. After the fluid pressure cylinder 2c urges the pressure roller 2d toward the feed roller 2b to pinch the material 3, the clamp tool 36 is brought into an unclamped state.
[0048]
The shear 4 is a known one provided with a fixed blade 4a and a movable blade 4b driven by a driving mechanism (not shown), and is disposed in front of the feeder 2 with a predetermined space between the feeder 4 and the feeder. Yes.
[0049]
The feeder 2 feeds the material 3 supplied from the uncoiler 1 between the fixed blade 4a and the movable blade 4b of the shear 4. When the feeding length of the material by the feeder 2 becomes equal to a predetermined cutting length, the feeding roller 2b of the feeder 2 is stopped and the feeding operation of the material 3 is stopped. Next, the movable movable blade 4b of the shear is lowered to cut the long material 3 to form a material plate having a predetermined length. This material plate is supplied to a processing apparatus such as a laminating apparatus. Measurement of the feed length of the material by the feeder 2 is performed, for example, by measuring the number of rotations of the feed roller 2b.
[0050]
In order to detect that the tail end of the long material 3 supplied from the uncoiler 1 to the feeder 2 has come off from the uncoiler 1 (the material roll has been rewound and the material has run out) A material shortage detection device 50 is provided that includes a light source 50a that generates light and a photodetector 50b that detects light generated by the light source. In the illustrated example, the light source 50 a is attached to the upper part of the surface on the uncoiler side of the processing machine side frame 40, and the photodetector 50 b is attached to the fixed frame 10 of the uncoiler 1. The light source 50a and the photodetector 50b are provided so as to face each other in a direction inclined with respect to the horizontal direction with the long material 3 unwound from the uncoiler 1 and supplied to the feeder 2 therebetween. The photodetector 50b of the material shortage detection device 50 is in a state where the tail end of the long material 3 is still restrained by the uncoiler 1 as shown by the chain line in FIG. When the long material 3 is interposed between the light source 50a and the photodetector 50b (when the light source 50a is blocked from the photodetector 50b), the generation of the detection signal is stopped. When the tail end of the long material 3 is detached from the uncoiler 1 and the light generated by the light source 50a reaches the detector 50b, the material has run out (from the uncoiler to the long material). A material shortage detection signal indicating that the tail end of the material has been removed) is output.
[0051]
In this example, when an out-of-material detection signal is generated, the motor 21 is stopped, or the uncoil shaft is stopped by cutting the clutch mechanism that has transmitted power to the uncoil shaft that has been rotating up to that point. At the same time, the feeding speed of the material by the feeder 2 is reduced.
[0052]
Further, in the vicinity of the feeder 2, when the tail end of the long material 3 is detached from the uncoiler 1, the tail end of the long material 3 passes through the judgment position P set in the vicinity of the feeder 2. A tail end detection device 51 for generating a detection signal is provided. The tail end detection device includes a light source 51a that generates light such as infrared rays, and a photodetector 51b that generates a tail end detection signal when light generated by the light source 51a is detected. The light source 51a is attached to the front end of the support arm 52, the rear end of which is fixed to the uncoiler side surface of the processing machine side frame 40 in a state of being positioned above the feeder 2 and positioned below the feeder 2. In this state, the photodetector 51b is fixed to the support 53 fixed to the processing machine side frame 40.
[0053]
In the illustrated tail end detection device 51, when a long material exists at the determination position P and the light source 51a and the light detector 51b are blocked, the light detector 51b stops outputting. When the tail end of the long material 3 passes the determination position P and the light detector 51b detects the light generated from the light source 51a, the tail end detection signal is output.
[0054]
Further, a tip detection device that outputs a tip detection signal when a tip of a long material pinched by the feeder 2 is detected at a set position Q set in a position close to the feeder 2 in front of the feeder 2. 54 is provided penetrating the guide plate 41.

The tip detection device 54 includes a light emitter that emits light toward a long material and a light receiver that receives reflected light generated by the long material, and detects reflected light of the light irradiated on the long material. Detectors that detect the presence or absence of a long material, or are on or off when they are in contact with or close to a long material, It can be configured by a detection switch or the like that is turned off or turned on when it is lost. Further, similarly to the tail end detection device 51, the tip detection device 54 can be constituted by a sensor of a type in which the light source and the photodetector are opposed to each other.
[0056]
In the present invention, the material held in the feeder 2 after the tail end detection signal is generated with the tail end detection signal output from the tail end detection device 51 and the tip detection signal output from the tip detection device 54 as inputs. Before the tail end of the feeder reaches the inlet of the feeder 2 (before the tail end comes off to the side of the shear 4), the feeding direction of the feeder 2 is switched to feed the material back to the uncoiler 1 side as waste material. The feeder control means for controlling the feeder so that the feeder 2 is stopped when the leading end of the material reaches the set position Q, and the material delivery device at the material delivery position A of the uncoiler 1 using the reversely fed material as waste material. A clamp tool control means for clamping the waste material to the clamp tool 36 and a clamp tool 36 that clamps the waste material are provided. Control device for controlling the uncoiler and the feeder, and a clamp tool moving mechanism control means for controlling the clamp tool moving mechanism for controlling the clamp tool moving mechanism so that the waste material is separated from the feeder by retreating away from the feeder (to the uncoil shaft side). It is prepared in.
[0057]
In the case where the control device is configured using a microcomputer, the feeder control means, for example, determines whether or not the material held in the feeder by using a tail end detection signal generated by the tail end detection device 51 is a waste material. A waste material judging means, a means for reversing the rotation direction of the electric motor 2a that drives the feeding roller 2b of the feeder 2 when the waste material judging means judges that the waste material is waste, and a tip detection signal is generated This can be realized by means for stopping the electric motor 2a.
[0058]
The waste material determination means is configured to detect the difference ΔL () between the length Lx of the long material 3 already fed by the feeder 2 and the cutting length Lc after the previous cutting is performed and before the tail end detection signal is generated. = Lc−Lx) is compared with the distance (the distance along the material) Lo between the determination position A and the inlet of the feeder 2, and when ΔL> Lo, the material held in the feeder is waste material. This can be realized by causing the microcomputer to perform a process for determining that there is a certain one.
[0059]
Further, the feeder control means can be configured to stop the motor 2a when the tail end detection signal is generated without performing the calculation of ΔL, and then reverse the rotation direction of the motor immediately thereafter.
[0060]
In the following description, for the sake of simplicity, it is assumed that when a tail end detection signal is generated, the material held in the feeder 2 is determined as waste as it is and the feeding direction of the feeder is reversed.
[0061]
The waste material detachment clamp tool moving mechanism control means performs a clamping operation to give a clamp command to the clamp tool 36 of the material delivery device at the material delivery position A of the uncoiler 1 to clamp the waste material when a tip detection signal is generated. And means for driving the clamp tool moving mechanism so as to retract the clamp tool 36 clamped with the waste material in a direction away from the feeder (to the uncoil shaft side).
[0062]
In the present invention, the waste material discharge position B (see FIG. 2) is set at a position separated from the material delivery position A of the uncoiler by a predetermined angle, the clamp tool 36 is moved and the waste material is separated from the feeder 2, and then the uncoiler. The clamp drive 36 that clamps the waste material is moved to the waste material discharge position B by operating the turning drive mechanism.
[0063]
In order to perform these operations, the clamp that clamps the waste material after it has been confirmed that the waste material has detached from the feeder is moved toward the waste material discharge position set at a position away from the material delivery position, and a new The turning drive mechanism control means for controlling the turning drive mechanism so as to position the uncoiled shaft holding the material roll at the material delivery position, and the waste material is clamped when the clamp that clamps the waste material reaches the waste material discharge position. A waste material discharge clamp releasing means for controlling the clamp tool to be in an unclamped state is provided in a control device for controlling the uncoiler and the feeder.
[0064]
In the illustrated example, as shown in FIG. 2, a waste material discharge position B is set at a position 90 degrees away from the material discharge position A, and the material delivery device positioned at the waste material discharge position is located at the waste material discharge position B. A transport device 61 that receives the dropped waste material released from the clamp tool 36 and moves it to the waste material processing space side and a waste material forming device 62 that forms the waste material transported by the transport device 61 into a coil shape are arranged. .
[0065]
The illustrated transport device 61 is formed of a bowl-shaped chute formed so that the cross section has a U-shape, and is disposed in a state inclined below the clamp tool 36 positioned at the material discharge position B. .
[0066]
The waste material forming apparatus 62 has a structure in which an electric motor 62a, a first metal forming roller 62b that is rotationally driven by the electric motor 62a, and an outer periphery of the metal roller are covered with a urethane rubber layer. A second forming roller 62c supported in parallel with 62b and displaceable with respect to the first forming roller, and the second forming roller 62c are urged toward the first forming roller 62b. Biasing means such as a spring and a cylinder are attached to a frame supported on the mount 62d. In the waste material forming apparatus, when the waste material is loaded, the second forming roller 62c is separated from the first forming roller 62b so that a gap for waste material loading can be formed between the two forming rollers. It has become. In the example shown in FIG. 3, the waste material (metal plate) sliding down in the chute constituting the transport device 61 is received in a waste material loading gap formed between the first and second forming rollers 62b and 62c. As described above, the positional relationship between the waste material forming device 62 and the transport device 61 is set.
[0067]
In the waste material molding apparatus 62 described above, the surface layer of the second molding roller 62c is made of urethane rubber and has elasticity. Therefore, a part of the first molding roller 62b is the second molding roller 62c. Rotates while biting into the surface layer. Therefore, the waste material (metal plate) supplied between the first and second forming rollers 62b and 62c is substantially along the outer peripheral surface of the second forming roller 62c curved by the first forming roller 62b. And is formed into a compact coil shape as indicated by reference numeral 80 'in FIG.
[0068]
The electric motor 62a of the waste material forming apparatus 62 is controlled by a timer that is activated when it is confirmed that the waste material is received between the first and second forming rollers 62b and 62c, and is driven for a set fixed time. Is done. The set time of the timer is set to a sufficient length necessary for forming the waste material into a coil shape.
[0069]
The waste material forming device 62 does not necessarily need to be composed of two rollers, a first forming roller 62b whose surface is made of metal and a second forming roller 62c whose surface is covered with rubber. For example, as shown in FIG. 4, a waste material forming apparatus 62 that is formed into a coil shape by passing waste material between three forming rollers R1 to R3 may be used.
[0070]
Next, the operation of the long material cutting apparatus will be described together with the operation of the waste material processing apparatus. When cutting a long material and supplying a raw material plate to a processing machine, first, the motor 25 of the uncoiler 1 is driven to turn the movable frame 13 so that a predetermined uncoil shaft is provided as shown in FIG. The held material roll, for example, the material roll 20 held on the uncoil shaft 14 </ b> A, is positioned at a material delivery position opposite to the inlet of the feeder 2. Next, the hydraulic cylinder 30A is driven to move the clamp holding frame 32A from the retracted position shown by the solid line in FIG. 1 to the advanced position shown by the chain line in FIG. 1, and at the position close to the inlet of the feeder 2 Simultaneously with stopping the holding frame 32A, the tip of the long material 3 is inserted between the feeding roller 2b and the pressure roller 2d of the feeder 2. Next, by releasing the clamp by the clamp tool 36 and rotating the uncoil shaft 14A holding the material roll to be rewound, the feeding roller 2b is driven while the material roll 1A is rotated in the rewinding direction, thereby making the long material 3 is fed to the shear 4 side. At this time, the clutch mechanism for intermittently transmitting the power to each uncoil shaft is turned off so that the power of the electric motor 21 is not transmitted to the uncoil shafts 14B to 14D holding the rolls other than the material roll for rewinding the long material. Keep it.
[0071]
When the feed length of the long material detected from the rotation speed of the feed roller 2b reaches a predetermined cutting length, the feed roller 2b of the feeder 2 is stopped and the uncoil shaft 14A is stopped, and the shear 4 is used to A material plate having a predetermined length is obtained by cutting the scale material. After the cutting by the shear 4 is completed, the uncoiled shaft 14A and the feeding roller 2b of the feeder 2 are restarted, and the feeding of the long material is resumed. By repeating these operations, a material plate having a predetermined length is sequentially supplied to a processing machine (not shown). When the formation of the material plate proceeds and the tail end (final terminal portion) of the long material 3 is detached from the uncoiler 1, the material shortage detection device 50 generates a material shortage detection signal. When the material out detection signal is generated, the uncoiled shaft 14A is stopped, and at the same time, the feeding speed of the feeder 2 is decreased.
[0072]
When the tail end detection device 51 detects the tail end of the long material 3, the feeding operation of the feeder 2 is stopped, the electric motor 2a is reversed, the feeding direction of the feeder 2 is reversed, and the feeder 2 holds. The material that is being used is sent back to the uncoiler as waste.
[0073]
Feeding the feeder 2 when the tip of the waste material being fed back toward the shear 4 side reaches the position (set position) where the tip detection device 54 is provided and the tip detection device generates a tip detection signal. Stop operation.
[0074]
Further, when the tip detection signal is generated, the waste material which is reversely fed and protrudes from the feeder 2 to the uncoiler side is clamped by the clamp tool 36 of the material delivery device 37A at the material delivery position A. After it is detected that the waste material has been clamped, the piston rod 31 of the cylinder 30A is retracted by a set distance Lo set longer than the distance between the set position Q and the inlet of the feeder 2, and the clamp 36 Is retracted by a set distance Lo toward the uncoil shaft 14 </ b> A, and the tip of the waste material clamped by the clamp tool 36 is detached from the feeder 2. After the tip of the waste material clamped by the clamp tool 36 is detached from the feeder 2 in this way, the electric coil 25 is driven to rotate the movable frame 13 to turn the uncoiled shafts 14A to 14D into the material delivery devices 37A to 37A. Turn together with 37D. As a result, the clamp tool 36 that clamps the waste material is moved toward the waste material discharge position B, and the uncoil shaft 14B holding the material roll to be rewound and the material delivery device 37B are moved toward the material delivery position A. .
[0075]
When the clamp tool 36 that clamps the waste material reaches the waste material discharge position B and the uncoil shaft 14B and the material delivery device 37B reach the material delivery position A, the electric motor 25 is stopped. At this time, as shown by reference numeral 80 in FIG. 3, most of the waste material is in a state of hanging down to the uncoil shaft 14 </ b> A side. After stopping the electric motor 25, the clamp tool 36 at the material discharge position B is unclamped, and the waste material 80 clamped by the clamp tool is dropped into the chute constituting the transport device 61, and the waste material 80 is removed. It slides down along the chute and the end portion is loaded between the forming rollers 62b and 62c of the waste material forming apparatus 62. When the end portion of the waste material 80 is loaded between the molding rollers 62b and 62c, the molding roller 62c is separated from the molding roller 62b to form a gap for loading the waste material between the molding rollers. After the end of the waste material is loaded between the molding rollers 62b and 62c, the molding roller 62b is urged toward the molding roller 62b, and the motor 62a is activated to rotate the molding roller 62b, thereby forming the molding roller 62b. , 62c, and the waste material is formed into a coil shape as indicated by reference numeral 80 'in FIG.
[0076]
In the above example, the waste material forming device 62 is provided in a state of being positioned below the clamp tool 36 at the waste material discharge position. However, as shown in FIG. 5, the waste material forming device 62 is moved to the waste material discharge position. It can also arrange | position so that it may be located ahead of the clamped tool 36 made. In this case, a base 63 for supporting the waste material forming apparatus 62 is provided, and the height of the base is set to an appropriate value, whereby the forming roller 62c is separated from the forming roller 62b and the waste material is disposed between the two forming rollers. When the gap for loading is formed, the gap is positioned on the extension of the tip of the waste material 80 clamped by the clamp tool 36 at the waste material discharge position.
[0077]
When the waste material forming apparatus is arranged in this way, when the clamp tool 36 that clamps the waste material 80 reaches the waste material discharge position, the clamp tool 36 is advanced to the waste material forming apparatus 62 side, and the clamp tool 36 is clamped. The clamp tool is moved so as to perform a waste material loading operation for loading the tip of the waste material 80 into the waste material molding apparatus 62 and a clamp releasing operation for bringing the clamp tool 36 into an unclamped state when the waste material loading operation is completed. Waste material loading clamp control means for controlling the mechanism and the clamp tool, and when the waste material loading clamp control means confirms that the clamp tool is in an unclamped state, the waste material molding apparatus is activated to form a waste material molding operation. The waste material forming apparatus starting means for performing the above is provided in a control device that controls the uncoiler 1 and the feeder 2. When loading the tip of the waste material into the waste material molding device 62, the molding roller 62c of the waste material molding device 62 is separated from the molding roller 62b to form a gap between the molding rollers, and the tip of the waste material is loaded. Then, the forming roller 62c is pressed against the forming roller 62b.
[0078]
If comprised in this way, after moving the waste material 80 to the waste material discharge position B, since the clamp tool 36 is moved to the waste material molding apparatus 62 side, the tip of the waste material 80 can be loaded into the molding apparatus 62. The waste material can be formed without providing the conveying device 61 as shown in FIG.
[0079]
In the above example, the waste material forming device 62 is disposed at the waste material discharge position B to form the waste material in a compact shape, but this forming device is not necessarily provided. Further, the waste material forming apparatus 62 is not limited to the one that forms the waste material in a coil shape, and may be one in which the waste material is folded, for example. Further, instead of the waste material forming apparatus, a cutting device for cutting the waste material into thin pieces may be provided.
[0080]
【The invention's effect】
As described above, according to the present invention, after the tail end of the long material is detected at the determination position set in the vicinity of the feeder, the feeding direction of the feeder is reversed before the long material reaches the inlet of the feeder. The material held by the feeder is fed back to the uncoil side as waste material, and the waste material is removed by a clamp provided on the uncoil shaft side when the tip of the waste material shear side reaches a set position set near the feeder. After clamping and pulling out from the feeder, the clamp that clamps the waste material is moved to the waste material discharge position, and the waste material is discharged at the waste material discharge position, so the new material roll is positioned at the material delivery position. The waste material can be automatically removed without human intervention in the process of performing the process. Therefore, it is possible to shorten the time required for the work for removing the waste material, shorten the operation stop time that occurs when removing the waste material, and increase the work efficiency.
[0081]
In particular, in the present invention, since the waste material discharge position is set at a position away from the material discharge position, even when a space for collecting the waste material cannot be secured in the vicinity of the material discharge position, the waste material can be easily processed. .
