  The present invention relates to an apparatus for cutting and collecting an outer circumferential binding band of a rolled metal band wound in a coil shape.

  Steel and non-ferrous metal strips are often handled as coils wound in a circular shape during the manufacturing process or at the time of shipment. These metal coils are bound by winding a narrow band around the outer circumference so as not to be unwound by its elasticity. As metal coils are transported between various processes such as rolling, annealing, and surface treatment processes, band binding and subsequent cutting are repeated so that the coil cannot be unwound. This is a major issue in streamlining the manufacturing process.

As a technique for automatically cutting a multi-strand band bound to the outer periphery of a coil, Japanese Utility Model Publication No. 7-30497 (Patent Document 1) discloses that a multi-strand binding band on the outer periphery of a coil is sequentially cut by one head. A collection device is proposed. According to the apparatus, a touch roll that protrudes and retracts into a coil provided on one cutter head, a photocathode-type coil end face detection, and a coil contact type machine that immediately stops the movement of the cutter head in the axial direction of the coil as soon as the band position is detected. A band cutter for a multi-band banding coil is described, wherein a band position detector having a general structure is provided, and an opening stroke of both blades of the cutter is restricted to about twice or less of a maximum width of a band to be cut. Yes.

FIG. 1 is a side view showing a state in which the band cutting device K according to the first embodiment is applied to a metal coil 50 placed on a cradle roll 53 and wound with a binding band 51.
As shown in FIG. 1, the band cutting device K of the first embodiment is opposed so that the rotation surfaces of the arm 3 and the bending arm 11 are parallel to the side surface of the metal coil 50 in the operating state.
As shown in FIG. 2, the band cutting device according to the first embodiment is movably mounted on two rails (41, 41) laid on the foundation floor 40, and is a base movement motor. By transmitting the rotation of 32 to the pinion 34 that meshes with the rack rail 42 via the drive chain 33, the rotation can be performed in parallel to the coil axis direction (the left-right direction in FIG. 2).
As will be described below, the band cutting device K of the present invention includes a cutting mechanism, a push-up mechanism, and a recovery processing mechanism as main parts.
Hereinafter, each will be described in detail.

<Cut mechanism>
As shown in FIG. 1, the cutting mechanism includes an arm 3 having an upper cutter head 1 and a lower cutter head 2 attached to the tip, a holding shaft 3a, an arm cylinder 3b, and a bridge 3c. The base end of the arm 3 of the cutting mechanism is pivotally attached to a rotating shaft 3 d of a horizontal base provided at the extended end of the base 31. The arm 3 rotates the upper cutter head 1 and the lower cutter head 2 at one end of the arm 3 between the A1 position and the A2 position by the expansion and contraction of the arm cylinder 3b attached to the bridge bar 3c provided in the intermediate portion. It can be rotated around the shaft 3d.
Here, the A1 position refers to a standby position of the two cutter heads (1, 2) disposed at the tip of the arm 3. In addition, the A2 position refers to a contact position between the two cutter heads disposed at the tip of the arm 3 and the metal coil 50.
The upper cutter head 1 and the lower cutter head 2 are rotatably attached by a support shaft provided on the holding shaft 3a. The reason why the mechanism can be rotated by the support shaft is to allow two cutter head surfaces (both upper and lower) having different contact positions on the outer surface of the coil to tilt in close contact with the arc on the outer periphery of the coil. .
In this cutting mechanism, two bands can be cut at the same time, and one end of the cut band is rotated upward to the position of A1 while being held by a grip provided on the cutter head (1, 2). Stop.

<Push-up mechanism>
The push-up mechanism includes a bent arm 11, a bent arm cylinder 12, and a band guide plate 10a each having a push-up split roll 10 attached to the tip. The bending arm 11 is rotatably connected to the bending arm cylinder 12 to a bridging bar 11a provided at an elbow which is a bending start portion. The distal end of the bending arm cylinder 12 is rotated upward and downward, and the push-up split roll 10 can be moved from the lower end position B1 to the upper end position B2.
Here, the B1 position refers to the standby position of the push-up split roll 10 disposed at the distal end of the curved arm 11, and the B2 position refers to the push-up split roll 10 and the introduction split roll 21 disposed at the distal end of the curved arm 11. The contact position.
Further, a band guide plate 10 a is attached so as to cover the push-up split roll 10 at the tip of the bent arm 11 slightly, and the cut band is moved along the contact line (surface) between the introduction split roll 21 and the push-up roll 10. It has a role to invade in more parallel direction.
The left and right rolls (10-1, 10-2) of the push-up split roll 10 can be rotated independently on the left and right sides. This push-up split roll serves to push up the two bands that have been cut and sandwiched between the grips from below to press against the introduction split roll 21.

<Recovery processing mechanism>
The recovery processing mechanism is disposed at the uppermost part of the main pillar 30 and includes an introduction division roll 21 having air motors (21 a, 21 b) at the opening of the through-plate guide part 20, and a winding / shrinking unit 22 at the rear part.
As will be described later (see FIG. 11), the introduction split roll is provided with air motors (21a, 21b) at both ends, and the rotation direction and the number of rotations of the two split rolls can be driven and controlled independently. The length X from the grip position G1 of the band 51a cut by the upper cutter head 1 to the split roll is shorter than the length Y from the grip position G2 of the band 51b cut by the lower cutter head 2 to the split roll. The left and right rolls of the introduced split roll can be brought into contact with the left and right rolls of the push-up split roll contacting from below. Accordingly, by separately rotating the left and right rolls of the introduction split roll forward and reverse, band tips having different band lengths (X, Y) from the introduction split roll to the grip position can be aligned.
Since the ends of the two cut bands that enter the through-plate guide portion 20 can be aligned, two band crimping processes can be performed simultaneously by one rotation operation of one band crimping unit. It has features that can.
As shown in FIG. 1, the spirally wound band waste can be collected from the lower part of the winding unit 22 through the shooter 23 into the lowermost wound band waste collection box 26.

Next, the structure inside the cutter head of the cutting mechanism and the operation of gripping and cutting will be described in detail.
As shown in the side view of FIG. 3A and the bottom view of FIG. 3B, the A and B grippers (72, 84) and the clamped band 51 are clamped before the band 51 is cut in the cutter head. The upper and lower blades (85, 75) to be moved move from both sides to the central band 51 position by driving the air motor 87.
Both ends of the screw shaft 60 are pivotally attached to the inner wall facing the long side direction of the cutter head by rotary bearings 83, respectively. A fixing nut 71 is screwed to one end of the screw shaft 60, and the fixing nut 71 is fixed to the slide block 70. A rotation nut 82 that is rotationally driven by the rotation of the pinion 81 is screwed to the other end portion of the screw shaft 60, and the rotation nut 82 is pivotally attached to the drive slide block 80.
Since the pinion shaft 86 is directly connected to the air motor 87, the rotational force of the pinion 81 due to the motor rotation is transmitted to the rotary nut 82 pivotally attached to the drive slide block 80.

When the rotation of the pinion 81 is transmitted to the rotary nut 82, both slide blocks (slide block 70, drive slide block 80) move in the center direction, respectively, but the screw shaft 60 and both nuts (fixed nut 71, rotary nut). 82), the order of which slide block starts moving toward the center first is determined, as will be described later.
As shown in FIG. 3A, a gripper holder 72a is slidably inserted into the bottom of the slide block 70, and an A gripper 72 is attached to the bottom of the slide block 70 by a gripper holder 72b. The A gripper 72 is pressed downward by a gripper spring 72d, and the gripper tip 72c functions to securely clamp the band 51.

In the cylindrical space provided inside the gripper holding body 72a, a spiral spring 70a is disposed so as to insert the spring guide rod 70b, and the buffering action and pressing when the A gripper 72 contacts the band 51. Add action.
A B gripper 84 is pivotally attached to the bottom of the other drive slide block 80 by a gripper pin 80a. The B gripper 84 is pushed downward by a gripper spring 84a, and the B gripper tip 84b functions to securely clamp the band 51.

Next, with reference to FIG.3 (b), the attachment structure of a pair of cutting blade is demonstrated.
The lower blade 75 is pivotally attached to the bottom of the slide block 70 by a lower blade pin 75a with the tip directed in the center direction. The lower blade spring 75b is attached to the middle portion of the lower blade 75 so as to press the lower blade 75 downward (toward the surface of the metal coil), and the lower blade tip is below the band 51 (gap between the coil and the band). It works to insert it securely.
The other upper blade 85 is pivotally attached to the bottom of the drive slide block 80 by an upper blade pin 85a with the tip directed in the center direction. The upper blade 85 is pressed downward (toward the surface of the metal coil) by the upper blade spring 85b, and the upper blade tip 85c functions to reliably hold the band 51 from above and not float. The lower portion of the upper blade tip 85c is provided with a notch corresponding to the thickness of the band so that it does not accidentally enter the lower side of the band (the gap between the coil and the band).

FIG. 4A is a side view of the cutter block (1 and 2 shown in FIG. 1 have the same structure) on the slide block 70 side. FIG. 4B is a side view of the drive slide block 80 side. The lower blade 75 and the A gripper 72 protrude slightly downward from the bottom surface of the cutter head (1, 2).
As shown in FIG. 4B, the upper blade 85 and the B gripper 84 protrude slightly downward from the bottom surface of the cutter head. When the bottom surface of the cutter head comes into close contact with the outer periphery of the target coil due to the protruding state, the pair of upper and lower blades (75, 85) and the pair of grippers (72, 84) can contact the coil surface with a pressing force and reliably capture the band.

As shown in FIGS. 4 (a) and 4 (b), one touch member 90 is attached to each bottom side of both long sides of the cutter head (1, 2). 3 (b)). A spring guide bolt 94 fitted with a spring 92 is screwed onto the slide base 93 of the touch member 90, and the touch roller 90 a pivotally attached to the holder 91 is pressed downward by the spring 92.
In FIG. 1, when the cutter head (1, 2) attached to the tip of the arm 3 rotates downward and approaches the outer periphery of the coil, the touch roller 90a first contacts the coil surface. The bottom surface of the cutter head (1, 2) is slid by the touch roller 90a pressed by the spring (92), and works to be in a stable surface contact state with the coil surface.
In addition, since the cutter head and the outer periphery of the coil are not brought into impact contact with each other due to the rotation and buffering action of the touch roller 90a, there is an effect that the mutual surfaces are not damaged.

FIG. 6 is a diagram for explaining a mechanism in which the lower blade 75 and the upper blade 85 provided on the bottom surface side of the cutter head come close to each other by the rotation of the screw shaft 60 and cut the band.
The rotation of the pinion is transmitted to the rotation nut 82 in the drive slide block 80, and further the rotation of the screw shaft 60 is caused. At this time, which of the slide block 70 and the drive slide block 80 in FIG. 6 moves toward the center first depends on which of the screw nut 60 and the rotary nut 82 is larger in the friction resistance against the screw shaft 60. It is decided whether to start.
FIG. 6 illustrates the case where the screw rotation friction resistance of the rotary nut 82 on the drive slide block 80 side is large. In this case, since the screw rotation frictional resistance on the rotating nut 82 side is relatively large, the rotation of the rotating nut 82 rotates the screw shaft 60 and the drive slide block 82 itself does not move. However, when the screw shaft is rotated, the other fixed nut 71 moves in the central direction (the direction of the band 51) together with the slite block 70.

And if the lower blade 75 of the bottom part of the slide block 70 moves and reaches the band 51, a movement will be stopped in the state which contacted lightly. In this state, there is not enough driving force for the lower blade 75 to enter under the band. When the slide block 70 stops, the rotation of the screw shaft 60 also stops. When the rotation of the screw shaft 60 stops, the rotational force of the rotating nut 82 screwed on the screw shaft 60 becomes a screw propulsion force toward the central portion of the rotating nut itself, and the movement of the drive slide block 80 (direction of the band 51) starts. To do.
As a result, as shown in FIG. 6B, the band 51 is sandwiched between the upper and lower blades from both sides, and the lower blade 75 starts to enter under the band at the center. Furthermore, the upper blade advances while holding the band at the notch at the tip, and a part of the tip of both blades crosses, and the band is cut as shown in FIG. A proximity switch (not shown) is operated at a position where a part of the upper blade and the lower blade cross each other for a predetermined length, and the rotation of the pinion is stopped.

FIG. 7 illustrates the moving mechanism of both the A and B grippers (72, 84) interlocked with the propulsion of both slide blocks (slide block 70, drive slide block 80) described in FIG.
After the left A gripper 72 of FIG. 7A reaches the band 51 (FIG. 7B), the right B gripper 84 approaches the band, and the band 51 is sandwiched by the gripper from both sides. ((C) in the figure). The A gripper 72 is pressed in the band direction by the spring 70a, and the gap between the ends of both grippers works in a direction that is constantly smaller than the band width, so that the end of the cut band can be securely clamped. It has become.

  Band clamping and band cutting proceed with the close movement of both slide blocks ((slide block 70, drive slide block 80), but after the band is gripped first, band cutting is performed. The entire cut band is lifted together with the upper rotation of the cutter head while the band ends are sandwiched between the pair of grippers at the bottom of the cutter head without falling down the outer periphery of the coil.

<Push-up mechanism>
Next, the structure and operation of the mechanism for further pushing up the cut band following the cutting mechanism will be described. FIG. 8 shows a pair of upper and lower cutter heads as the cutting mechanism of the apparatus of the present invention, which is pushed by the arm cylinder 3b and the arm 3 is tilted forward and arranged in the vertical direction and the band cutting range is shifted in the coil width direction. (1, 2) shows a state in which the contact is made so as to follow the curvature of the outer peripheral surface of the coil and the inclination in the core axis direction. In such a contact state, grip clamping and cutting of the band 51 are performed on the bottom surface of each cutter head.

Next, FIG. 9 shows an end state of the cutting mechanism. The ends of the two cut bands 51a and 51b are gripped by the cutter head and stopped at the A1 position. When the cutter heads 1 and 2 lift the ends of the bands (51a and 51b), the position of the cutter head 1 is above the position of the cutter head 2. The bands (51a, 51b) hang down due to their own weight.
Following the state of FIG. 9, the push-up mechanism shown in FIG. 10 starts. FIG. 10 shows a state where the push-up split roll 10 located under the cutter head pushes up the band 51 by the upward rotation of the bending arm 11. The push-up split roll 10 comes into contact with the introduction split roll 21 and the movement of the bending arm 11 is stopped in a state where the band is sandwiched between both split rolls.

<Recovery processing mechanism>
FIG. 11 is an explanatory view of the state of FIG. 10 as viewed from the front of the present apparatus. The band 51 a sandwiched by the upper cutter head 1 is held by the split roll on the left half of the push-up split roll 10 and the introduction split roll 21.
On the other hand, the band 51 b held by the lower cutter head 2 is held by the split roll on the right half of the push-up split roll 10 and the introduction split roll 21.
In this state, the upper cutter head 1 and the lower cutter head 2 have different distances (X, Y) from the introduction split roll 21 and the band lengths between them.

  Therefore, the rotational speeds of the air motors 21a and 21b provided on the left and right sides of the introducing split roll 21 are controlled independently to make the rotational lifting length of the band of the cutter head 1 different from the rotational lifting length of the band of the cutter head 2. Therefore, it is a mechanism that aligns the sagging tips of both bands. Further, a pair of band guides 24 are installed on the left and right sides of the front surface of the introducing split roll 21 so that the rotation axis is vertical, and two bands are smoothly introduced into the through-plate guide part 20.

FIG. 12 shows a state in which the left and right split rolls of the introduction split roll 21 are rotated in different directions in the direction of the arrows, and the ends of the bands 51a and 51b are aligned. That is. In the band 51b having a long introduction split roll position and a grip position (Y length in FIG. 11), the rotation speed of the introduction split roll is increased to align the end of the band 51b with the end of the band 51a. Thus, by providing the introduction division roll and independently controlling the rotation, the tips of both bands (51a, 51b) can be easily aligned.
FIG. 13 shows a state where both band tips (51a, 51b) are pulled up to the introduction division rolls and aligned, and then the introduction division roll 21 is reversed in the direction of the arrow to simultaneously feed both bands into the plate guide portion 20. ing. The tip ends of both bands are further fed while maintaining a space left and right, and as shown in FIG.

  FIG. 15 illustrates the mechanism of the crimping process of the crimping unit 22. The band 51 is sent out by the transport roll 95 and the high pressure roll 96 and is abutted against the lower bent portion of the anvil 97 on the exit side. Then, the band undergoes bending deformation and turns into a band scrap that has been subjected to a spiral-shaped crimping process. The angle of the anvil 97 is variable with the upper support shaft 97a as a fulcrum. The anvil 97 can be changed and fixed by adjusting the pressure head 98 a pushed by the pressure cylinder 98 and the anvil stopper 99. The anvil angle is adjusted to set the diameter of the spiral band waste to about 150 to 250 mm. The band waste that has been wound in a spiral shape passes through the lower shooter 23 and is collected as waste.

  Bands cut at the same time by two cutter heads can be collected at the same time as band scraps that have been wound in a spiral shape by transporting them to the crimping unit with the tip aligned with a separately controllable roll. Time can be shortened. Furthermore, it is possible to reduce the apparatus cost by simultaneously processing the two cut bands with a single crimping unit.
