DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is an apparatus for effectively supplying packing paper of different types, paper qualities, dimensions, etc., particularly steel strips in cold rolling mills and the like. When packing coils, it is large and heavy, and the coil diameter and width dimensions are different, and the quality of packing paper such as threaded paper, threadless paper, resin coated paper, polyethylene film, etc. is also different. A suitable turret type packing paper feeding device. The turret type packing paper supply device according to the present invention is versatile as described below, and is not limited to packing of steel strip coils and is applied to fields other than the steel industry. Of course, you will get it.

(Prior Art) Conventionally, as a turret type packing paper supply device for use in the packing of the above-mentioned form, for example, a device disclosed in JP-A-60-148431 is known. This device
As shown in FIG. 5, with respect to one base paper roll (10) rotatably supported inside the turret (1) along its circumference, a guide roll (11) and a running amount measuring means (26 ), A paper feed source (21) for drawing out the paper and a guide plate (14) for guiding the drawn paper to the outside of the turret are installed as many as the number of the paper rolls (10). Further, as a known technique, in a turret type packing paper feeding device equipped with a plurality of base paper rolls as shown in FIGS. 6 and 7, the turret (1) is rotatably supported along the outer periphery of the turret (1). For each base paper roll (10) that is present, the paper supply source consisting of the guide roll (A), the guide roll (B) and the bending plate (C) for correcting the shape of the drawn paper is used as the base paper roll (10). However, there is a device in which a pair of retractable feed rolls (21) and a packing paper cutter (18) are arranged in this order at a position corresponding to the packing paper supply position set outside the turret.

(Problems to be Solved by the Invention) However, in the device disclosed in JP-A-60-148431 shown in FIG. 5, the feed roll (21)
Since the guide plate (14) is installed on the exit side of the sheet, when a polyethylene film with a thickness of 50 to 100 μm, which is not rigid, is targeted, the top end of the feed paper ( 17) falls due to its own weight, and the outside of the guide plate (14), that is, the feed roll (2
There is a problem that the packing paper supply cannot be performed reliably and becomes a bottleneck for automation due to the need for manual intervention due to the entry into the 1) side or the suspension.

On the other hand, in the known device shown in FIGS. 6 and 7, the feed roll (21) is placed at a position away from the turret (1).
If you install, the so-called curl remains on the packing paper,
In the case of rust-proof paper coated with polyethylene on one side, warpage often occurs due to the temperature and humidity. If the feed roll (21) is not pressed beyond the curl, the rust-proof paper will be folded. It deteriorates the packaging after packing. To avoid this, feed roll (2
A sufficient margin is required between 1) and the cutter (18), and when the distance between the curving plate (C) that rotates with the turret (1) and the feed roll (21) is added, it is pulled out from the base paper roll (10). Fed paper edges (17)
However, about 600 mm remains after being cut by the cutter (18), and this can move freely with the rotation of the turret (1), causing a hang during the feeding of packing paper and making stable packing paper supply difficult and an automated line. There was a problem that could not be applied to.

On the other hand, the turret type packing paper supply device has an advantage that it is relatively hard to be restricted in space as compared with the ceiling storage type in which a large number of broadcast base paper roll groups are stored in parallel in the ceiling space, but JP-A-60-148431 In the case of the device disclosed in the publication, 1
One guide roll (11) for each base paper roll (10)
Book, 2 feed rolls (21), guide plate (1
4) and further guide rolls (11) and feed rolls (2
A base paper web running amount measuring means (26) is provided between 1), and when the number of base paper rolls (10) increases, the same number of sets as the guide rolls (11), feed rolls (21), guide plates (14) and A running amount measuring means (26) is required. The type of packing paper is not limited to paper with thread, and it is intended for packing paper such as polyethylene film. Considering different diameters and widths of steel strip coils, the number of paper strip coils mounted on the turret is, for example, steel strip. Coil inner diameter: 508mm, outer diameter: 600-1600mm, width: 500-1600mm
If the folding margin is 50 mm, the required paper strip coil width will be 692 to 2792 mm, and the paper strip coil width will be set to 1100 to 2800 mm and the paper strip coil width will be set to 300 mm pitch when the dimensions vary in the range Then 6 pieces, 3 kinds of packing paper, 3 kinds of film, 2 pieces of film
As for the types, a total of 30 are required. Even if they are mounted on the turret in the order of frequency of use, 15 or more are required, and there is still the drawback of being restricted by space. In the prior art shown in FIGS. 6 and 7, this is 1
The same applies because the guide roll (A), the guide roll (B) and the bending plate (C) are provided for the base paper roll (10) of the book.

(Means for Solving Problems) The present invention has been made in view of the above-mentioned circumstances,
In a paper feeding device for packing steel strip coils, etc., even if the paper strip coils to be installed have different characteristics, the structure inside the turret can be continuously and automatically operated even if the number of paper strip coils is 15 or more. Raise to a level that can withstand,
Moreover, it is an object of the present invention to provide a turret type packing paper supply device that can maximize the space by combining the overlapping mechanisms in one place.

Tension is applied to the packing paper for the minutes, and the supply paper (P) is cut by the cutter (18) and the guide plate (27) which is vertically set by the air cylinder (28).
When the cutting of the supply paper (P) is completed, the feed roll (2
1) is retracted by the air cylinder (20), and the structure (1) is in a rotatable state in order to supply the packing paper to be supplied next. When the pinch roll (31) is opened by the air cylinder (32), the packing paper (P) leaves the packing paper feeder and the packing paper supply is completed. Incidentally, (33) is a steel strip coil. Numerals (34) and (35) are stay dampers, which are used to replace the guide roll (11) and the guide plate (14) with the shaft (9) when replacing the base paper strip coil.
It functions to reduce the force of opening around.

(Effects of the Invention) As described above, the turret type packing paper supply device according to the present invention is provided with a guide roll in the immediate vicinity of each of the base paper rolls that rotate together with the structure (turret).
Since the guide plate is installed at a position in contact with the guide roll, the end of the supplied paper can be always held even if the packing paper is a curling paper or a packing paper having no curling and no rigidity. Further, since the feed roll is provided outside the structure and the guide roll is pressed and rotated to feed the packaging paper, the length of the end of the feeding paper after cutting can be shortened, and further, the feeding paper length measuring means can be provided. Since it is compactly installed on the feed roll, the following effects are achieved.
