Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a process equipment for continuously processing strip-shaped plate materials (hereinafter referred to as strips) such as rolled strip steel, in which a plurality of lines are on the same center line. The present invention relates to a belt wrapper for a strip winder used when the sheets are arranged in a stack.

<Prior art> In the recoiling line, which is the final process of strip products, usually, while coiled strip material is unwound into a strip shape by a rewinding machine, side trimming is performed by a side trimmer, and plate warpage is corrected by a tension leveler. Or, after performing various works such as oil for rust prevention, and then inspecting the shape of the plate and surface flaws, the product coil is wound up or down by a winder. A belt tipper is usually used during the first few windings when the strip tip is introduced around the winding shaft (hereinafter referred to as the mandrel) of this winding machine and the strip tension reaches the required winding force. To do. The subsequent winding is continued with the belt wrapper removed from the mandrel.

An example of the belt wrapper conventionally used in the recoiling line is shown in FIG. 3, which is a schematic front view seen from the working side. The drive side is substantially symmetrical to this figure, so its illustration is omitted.

In the figure, 1 is a strip, 2 is a pinch roll on the line exit side, 3 is a main body supporting frame attached to a base 4, 5 is a mandrel of a winder, and Z is a strip advancing direction (line advancing direction). As shown in the figure, the present apparatus comprises a pair of left and right guide rails 6 extending above the mandrel 5 along the line center line (that is, the strip width center line), a traveling carriage 7 that moves along the rails 6, and The pair of traveling drive cylinders 8, the belt wrapper main body frame 9 suspended and supported by the traveling carriage 7, and the pair of swing arms 10a, 10b mounted below and above the mandrel 5 side end of the frame 9.
And a pair of drive cylinders 11a and 11b, an endless belt 12 for introducing and winding the strip 1 on the mandrel 5, and guide roller groups 13a to 13h thereof, and a belt.
Tension device 14 that gives tension to 12 and guide plate 1 that is tiltably attached to swing arms 10a and 10b
It is composed of 5a, 15b and its driving cylinders 16a, 16b. The main body frame 9 forms a rigid structure with side plates 9a and 9b, which are opposed to each other across the belt 12 on the working side and the driving side, and a plurality of beams (not shown) connecting the both members. The guide rollers 13b, 13c, 13d, 13f, 13g are rotatably attached to the frame 9, and among them, the rollers 13b, 13g
At both ends of the shaft 17 of the swing arm 10a,
10b is supported by a pair of cylinders 11a and 11b attached to the pair of frame side plates 9a so as to be tiltable in the vertical direction. Here, the main body frame 9 is advanced so as to be set to the winding position as shown in FIG. Has been done. Further, the tension device 14 is configured to move up and down a guide roller (tension roller) 13e via a cylinder 14a along a guide 14b of the body frame side plate 9a. Further, in the figure, 18 is a tilting guide table, 7a is wheels, 18
Is a support frame for the guide rails 6 attached to the base 4, Z ₁ , Z
Reference numeral ₂ denotes a traveling direction of the strip 1 when the strip 1 is wound up and down, and 1'is a coil strip when winding is completed.

With the above configuration, for example, when the strip 1 is wound up, the mandrel 5 is started in the arrow direction (clockwise direction) as shown in the figure, and then the traveling cylinder 8 is used to move the body frame 9 to the main frame 9.
And move the belt 12 to the mandrel 5 at a preset pressure.
To crimp. Furthermore, cylinders 11a, 11b, 14a and 16a, 16b
The belt 12 around the mandrel 5 and the lower guide plate 15b to the strip path Z ₁
While the upper guide plate 15a is opened and set at an appropriate angle. In this case, it is assumed that the guide table 18 on the entry side is set to the upper winding position in advance. Next,
The tip of the strip 1 is fed into the mandrel 5 by the pinch roll 2. Thus, the strip 1 is introduced by the belt 12 and begins to wind smoothly. When the strip tension reaches the required winding force, the lower swing roller 13
Open a to retract the main body frame 9 to the standby position (shown by the chain line in the figure), and continue the winding. In addition,
In the case of the lower winding, the procedure is the same as that described above except that the mandrel 5 is rotated counterclockwise and the lower swing roller 13a is opened and replaced with the upper swing roller 13h.

<Problems to be solved by the invention> By the way, in recent years, the requirements for appearance quality of strip products have become more and more strict, so that the weight of inspection work increases during various operations on the recoiling line, and the inspection section The total length of the (inspection table) is about 40% of the total length of the line. In this case, the total length of the line becomes long, for example, about 50 m or more, and it becomes difficult to secure the installation place. As a means for dealing with this, there is a case where the inspection section which is the latter stage of the line is separated and overlapped on the upper section of the former stage to form a two-stage pass arrangement. Therefore, at this time, it becomes necessary to install the strip coil supply and winding device in the upper and lower paths, respectively.

However, when such a two-stage pass arrangement is used, the cost of the equipment increases due to an increase in the weight of the upper-pass (inspection table) support frame due to the increase in the number of layers and an increase in the number of coil rewinders, winders, and the like. There are drawbacks. Therefore, with regard to the rewinding and rewinding machines, which require relatively high equipment costs, it is conceivable to use one for each of the upper and lower paths. Of these, the rewinder can be easily shared, but the winder has a large difference in the approach angle of the strips that enter the mandrel from the upper and lower passes. It was not possible to wind it smoothly even if it was installed at the middle level of the upper and lower passes. Therefore, conventionally, two winding machines and two belt wrappers had to be installed.

In view of such problems, it is an object of the present invention to provide a belt wrapper that allows one winder to be commonly used for upper and lower multi-pass arrangements.

<Means for Solving the Problems> The configuration of the present invention that achieves the above-mentioned object is, in a belt wrapper that introduces and winds a strip-shaped plate material onto a winding shaft of a winder at the initial stage of winding, at least the strip-shaped plate material. The posture of the belt wrapper can be changed around the axis of the mandrel according to the two upper and lower approach directions, and the main body frame that supports the belt wrapper is suspended via a pivot on a traveling carriage that can move in the path line direction along the rails. A tilting drive device that supports the body frame downwardly and tilts the body frame in a vertical plane including the pass line about the pivot is installed between the body frame and the traveling carriage.

<Operation> In the above configuration, by running and tilting the main body frame, it is possible to smoothly introduce and wind the band-shaped plate members on the exit side of the upper and lower stages into the winder.

<Embodiment> Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings.

1 and 2 are front views of a path switching type belt wrapper according to this embodiment. It should be noted that the same or similar parts as those of the conventional one are designated by the same reference numerals, and overlapping description will be omitted.

As shown in both figures, the upper ends of both side plates 9a of the main body frame 9 on the mandrel 5 side are connected by a shaft 20, and both ends of the shaft 20 are
A pair of bearings 21 provided at the lower portion of the traveling carriage 7 are rotatably suspended and supported. Further, a connecting beam 22 is provided at an appropriate position above the side plate 9a, and a tilting drive device 23 is attached to the central portion of the connecting beam 22 in the longitudinal direction. This tilting drive device 23 is mounted on the traveling carriage 7 so that the pivot 23
The tilt drive cylinder 23b is a trunnion type liquid cylinder rotatably supported by a, and the tip of the rod is rotatably connected to the connection beam 22 via a pin 23c. As a result, the body frame 9 can be set and held at an arbitrary angle. The tilt drive device 23
A cylinder is used in this embodiment, but a screw jack or the like may be used as long as it has an elevating function capable of tilting the body frame 9.

The operation of the device of the present invention having the above configuration will be described. First
The figure shows the recoiling line on the upper and lower two stages.
FIG. 2 shows a state in which the strip 1 on the output side of the lower pass A ₁ is wound up when the strips 1 are stacked on A ₂ and A _1, and the strip 1 on the output side of the upper pass (inspection line) A ₂ is being wound up. It shows the state. In the drawing, 3 'denotes a Frames for the upper path A _2.

First, in the case of the lower path A ₁ , the main frame 9 of the belt wrapper is lifted by the tilting drive cylinder 23b in substantially the same manner as in the conventional device (FIG. 3) and is held in the horizontal state, and the same procedure as the conventional device is performed. The upper winding or the lower winding can be performed according to the above. On the other hand, in the case of the upper and lower windings of the upper path A ₂ , the traveling drive cylinder 8 and the tilt drive cylinder 23b are appropriately operated to move the strip 1 in the advancing direction Z ₁ or Z ₂
Accordingly, the body frame 9 is tilted and set to a position (angle θ ′) where the strip 1 can be smoothly introduced into the mandrel 5.
Although not shown, the setting operation of the tilting position (θ ') of the main body frame 9 can be automatically set by a generally known control means. Hereafter, the winding can be easily started by the same procedure as the conventional device.

Although the upper and lower two-pass recoiling lines have been described in the case of the present embodiment, the present invention is not necessarily limited to the two-pass line, and various process lines may be arranged in two or more stages. Is also easily applicable.

Further, although the present embodiment is applied to a recoiling line, the present invention can be applied to other various process lines for continuously processing strips.

<Effects of the Invention> As described in detail above with reference to the embodiments, in the path switching type belt wrapper according to the present invention, the main body frame is set at an arbitrary angle with respect to the traveling carriage by the tilt drive device.
Since it can be held, a combination of this tilting and movement in the line center direction by the traveling drive device can correspond to a plurality of strips on the exit side of the pass line which are arranged on the same line center line in the upper and lower directions. It is possible to use the same take-up machine in common, which greatly contributes to the reduction of the equipment cost and the versatile line configuration. Further, if one winder is shared in this way, it is necessary to pause the other pass lines that are not being wound, but during this time, for example, if the lower pass is paused in the recoiling line. ,
There is also an advantage that it is possible to perform operation preparations such as side trimmer blade replacement or roll correction work of shape correction equipment, or inspection and maintenance of equipment.
