Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a belt wrapper used for winding a thin strip metal material into a coil.

[0002]

[Prior art]

 In the rolling equipment for thin strip metal material (hereinafter referred to as strip), the strip that has exited the finish rolling mill is sent to a winder through a hot run table and wound into a coil. In such a winding machine, a belt wrapper for guiding the strip is used at the beginning of winding the strip. (1) An error in mechanical accuracy in manufacturing and installing the winding machine. (2) Deflection due to asymmetry of the mechanical system. (3) Difference in circumferential length and difference in thickness of the belt. (4) Asymmetric belt property. The meandering may occur due to factors such as the above, and in particular, the meandering often occurs due to a belt trouble.

In order to solve such a meandering phenomenon, a plurality of sets of frames that can approach and separate from the take-up drum are provided around the take-up drum, and each of the frames has an axis line of the take-up drum. Attach an arm that can rotate in the same direction as the rocking frame to a rocking frame that is mounted so that it can rock in a direction orthogonal to each other, and attach an endless belt to each rocking frame and arm. A belt pulley wound in a drivable manner provided in parallel with the winding drum (Japanese Utility Model Laid-Open No. 58-81015), or

A guide that does not come into contact with the belt at the time of upper winding and that comes into contact with the belt at the time of lower winding by utilizing the operations of the upper arm for upper winding that operates during upper winding and the leading arm for lower winding that operates during lower winding By providing a roller and using it as a meandering adjustment roller exclusively for lower winding that can be adjusted with adjustment bolts, it has no effect at the time of upper winding and corrects the meandering only at the time of lower winding. An upper and lower winding belt wrapper (Japanese Patent Laid-Open No. 4-8620) has been proposed in which a meandering adjusting roller dedicated to the reverse winding is provided so that it does not affect the winding during the lower winding and the meandering is corrected only during the upper winding. ing.

[0005]

[Problems to be solved by the device]

 The device disclosed in Japanese Utility Model Laid-Open No. 58-81015 is provided with a plurality of sets of frames that can be brought into and out of contact with a winding drum, and a pair of rocking frames are attached to the frames to make the rocking frame. Since each arm is equipped with a belt pulley, and each swing frame and arm are equipped with belt pulleys, not only is the structure complicated and expensive, but adjustment and maintenance are extremely troublesome.

In the invention disclosed in JP-A-4-84620, the belt wrapper is provided with a meandering adjusting roller for lower winding and a meandering adjusting roller for upper winding only, and the inclinations of these adjusting rollers are adjusted by adjusting bolts. This is to prevent the strip from meandering, but not only is the structure complicated and expensive, but the tilt of the upper and lower meandering adjustment rollers must be adjusted by adjusting bolts each time. Therefore, it was extremely troublesome and required a lot of adjustment time until the winding condition was stabilized.

The present invention has been made to solve the above problems, and an object of the present invention is to obtain a belt wrapper capable of preventing the meandering of the strip with a simple and inexpensive structure.

[0008]

[Means for Solving the Problems]

 The belt wrapper according to the present invention is provided with at least one strip in the length direction of the back side surface of the endless belt which is wound around the outer periphery of the winding drum by being tensioned by a plurality of winding rollers. The ridge is provided, and a groove into which the ridge is fitted is provided on the outer peripheral surface of the winding roller with which the ridge of the belt abuts.

[0009]

[Action]

 When the strip is fed, the strip is taken up between the winding drum and the belt, and is wound while being pressed against the winding drum. During this time, the ridges of the belt are fitted into the grooves of each winding roll, and the belt travels using the grooves as guides. As a result, the belt does not swing to the left and right, and therefore the strip does not meander.

An upper arm 4 is rotatably attached to the main beam 2 and is driven by a cylinder 5 to open and close. Reference numeral 6 denotes a guide arm rotatably mounted on a piston rod of a cylinder 7 mounted on the upper arm 4, and 8 a lower arm rotatably mounted below the main beam 2, which is driven by a cylinder 9. , Open and close.

Reference numeral 10 denotes a tensioning arm having an upper end rotatably attached to the main beam 2 on the side opposite to the upper arm 4 and the lower arm 8, and is driven by a cylinder 11 to rotate. 12a and 12b are provided on the upper arm 4, 12c and 12d are provided on the lower arm 8, 12e and 12f are rotatably attached to the tensioning arm 10, and 15a is a base of the upper arm 4. Numeral 15b is a flat roller rotatably attached to the base of the lower arm 8 and numeral 15c is rotatably attached to the main beam 2. 16 is a take-up drum around which a strip 17 (indicated by broken lines in the figure for easy understanding) is taken up, and 18 is an endless endless roller which is wound around grooved take-up rollers 12a to 12f and flat rollers 15a to 15c. It is a belt.

In the present invention, as shown in FIGS. 2 and 3, in the vicinity of both edges in the width direction of the back side surface of the belt 18, the ridges 19 are provided in the lengthwise direction and the ridges 19 contact. Grooves 13 into which the protrusions of the belt 18 are fitted are provided on the outer peripheral surfaces in the vicinity of both ends of the grooved winding rollers 12a to 12f in contact with each other. The ridges 19 are provided with slits 22 at predetermined intervals in order to prevent the pole portions of the winding portion from being deformed.

In the embodiment, a tape-shaped seat 20 made of polyurethane is adhered with an adhesive in the length direction near both edges in the width direction of the back side surface of the belt 18, and the polyurethane sheet is placed on the seat 20. The ridges 21 made of aluminum were welded to form the ridges 19.

Next, the operation of the present invention configured as described above will be described. FIG. 1 shows an example in which the present invention is applied to a belt wrapper for winding only in the winding direction. A belt 18 is wound around winding rollers 12a to 12f with grooves and flat rollers 15a to 15c, and a winding drum. It shows a state in which it is wrapped so as to wrap almost three quarters of sixteen.

At this time, the protrusions 19 of the belt 18 are fitted in the grooves 13 of the grooved winding rolls 12a to 12f, and the flat rolls 15a to 15c and the take-up drum 16 include the front surface of the belt 16. (The surface on which the ridge 19 is not provided) is wound. The tension arm 10 is driven by the air cylinder 11 to rotate in the direction of arrow a to apply tension to the belt 18, and the grooved winding roll 12 a provided on the upper arm 4 is wound by the cylinder 5. Since the belt 18 is wound around the surface of the winding drum 16, the belt 18 is wound around the grooved winding rolls 12a to 12f, the flat rolls 15a to 15c, and the surface of the winding drum 16, and the ridges 19 of the belt 18 are Each of the grooved winding rolls 12a to 12f is fitted in the groove 13.

Now, when the strip 7 is fed from the previous step, the strip 7 is guided by the guide arm 6 and taken between the winding drum 16 and the belt 18, and is pressed onto the winding drum 16 by the belt 18. It gets caught while being caught. During this time, since the tension force is applied to the belt 18 by the tension arm 10, the protrusion 19 of the belt 18 is fitted into the groove 13 of each grooved winding roller 12a to 12f. Therefore, since the belt 18 travels using the groove 13 as a guide, it does not swing to the left and right, and as a result, the strip 17 is also wound around the winding drum 16 without meandering.

When the strip 17 is wound 3 to 4 times around the winding drum 16, the guide arm 6 is driven by the cylinder 7 to be in the open state, and then the upper arm 4 is rotated by the cylinder 5 to be in the open state. Then, the main beam 2 is driven by the cylinder 3 to rotate in the direction of the arrow a, the belt 18 is detached from the winding drum 16, and the winding drum 16 continues to wind the strip 17, as shown in FIG. At this time, the belt 18 is stretched around the grooved winding take-up rollers 12a to 12f and the flat rollers 15a to 15c so that the belt 18 is not loosened by the tension arm 10, so that the ridge 19 separates from the groove 13. There is no such thing. When the winding work of the strip 17 is completed, the coil is taken out, and the main beam 2 is rotated by the cylinder 3 in the direction opposite to the arrow a to return to the original state before the new strip is attached, and the belt 18 is wound. It is wound on the take-up drum 16 and the next strip 17 is taken up.

In the above description, an example in which the present invention is applied to a belt wrapper for lower winding is shown, but the present invention can also be applied to a belt wrapper for upper winding or a belt wrapper for upper and lower winding. Further, although the case where the main beam 2, the upper and lower arms 4, 8 and the tensioning arm 10 are driven by the cylinder is shown, a driving means other than the cylinder may be used.

Further, an example is shown in which the belt 18 is provided with two ridges 19 and the grooved winding rollers 12a to 12f are provided with two ridges 13 corresponding thereto. The groove 13 may have one line or three or more lines. Further, the ridge 19 shows a case in which the polyurethane seat 20 is adhered to the back surface of the belt 18 with an adhesive, and the polyurethane ridge 21 is welded thereon, but other materials may be used. Alternatively, the seat 20 may be omitted and the ridge 21 may be directly adhered to the belt 18, or the ridge 19 may be integrally formed when the belt 18 is manufactured. .
