Abstract

PURPOSE:To efficiently remove dust and to transport a spool at a minimum distance through the lower part of a rolling mill without wetting the spool by opening a spool transporting passage to prevent dust from falling down on this passage when a dust shoot is closed, closing the spool transporting passage when a dust shoot is opened and providing a switching means to guide the dust to a dust collecting means. CONSTITUTION:While a foil 7 is rolled by rolling rolls 2, a switching part 21 of the dust shoot 19 is opened, dust such as scrap, roll coolant oil which fall down from the side of the rolling rolls is guided by a dust shoot 19 to a dust collecting means 16 and the passage of the spool transporting means 10 is closed. When the spool is handled, the switching part 21 of the dust shoot 19 is closed, the spool 5 of the rewinding reel 4 is lowered by a spool lowering means 12 on the passage of the spool transporting means 10 and transferred to the lower part of a winding reel 8 through the lower part of the rolling rolls 2. Then, the spool 5 is mounted by a spool elevating means 15 on the winding reel 8. At this time, the switching part 21 is closed, therefore, the spool 5 is not wetted by oil.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a metal foil rolling machine that rolls metal foils such as aluminum foils and fI foils.

(Prior Art) In a metal foil rolling mill, for example, an aluminum foil rolling mill, the handling method of transferring the spool from the inlet unwinding reel to the outlet winding reel has conventionally involved transferring the spool under the rolling mill. There is a method of transferring under the rolling mill and a method of transferring the working side or drive side of the rolling mill.

On the other hand, for scrap processing of aluminum foil that falls under the rolling mill due to foil breakage, etc., there is a first wire mesh conveyor that carries the scrap from the exit side to the input side directly below the rolling mill, and a second wire mesh conveyor placed at right angles thereto. It is taken out to the working side of the rolling mill.

Therefore, if a wire mesh conveyor is installed below the rolling mill, the spool handling cannot be transferred above the rolling mill, so a method is adopted in which the spool handling is transferred to the work side or drive side of the rolling mill using a coil car.

(Problem B to be Solved by the Invention) As mentioned above, when a wire mesh conveyor is installed under the rolling mill, spool handling under the rolling mill cannot be performed. That is,
Spool handling is quick and efficient as the shortest distance is under the rolling mill, but when the spool passes under the rolling mill it gets wet with roll coolant oil and roll coolant fumes come out from the opening for the spool to pass through. The winding coil gets wet with fume. However, when the working side and drive side of the rolling mill are transferred and spool handling is done,
The transportation distance is long and it takes time, and at the same time, the equipment cost is also high.

The present invention was provided for the purpose of solving such conventional problems, and it is possible to efficiently remove dust such as scrap, and also to transport the spool through the bottom of the rolling mill in the shortest distance without getting wet. In addition, the metal foil rolling machine can block the fume rising from the bottom of the rolling mill during rolling, allowing high-quality foil to be rolled without getting the winding coil wet with fume.Furthermore, the dust treatment equipment and spool handling equipment can be simple and inexpensive. It provides:

(Means for Solving the Problems) As a first means for achieving this, the present invention introduces a metal foil wound around a spool attached to an unwinding reel into a rolling roll and rolls the rolled metal foil. A metal foil rolling machine that winds foil onto a spool attached to a take-up reel,
spool lowering means for lowering the spool of the unwinding reel; spool conveying means for conveying the lowered spool to the lower part of the take-up reel via the lower part of the rolling roll; and winding of the spool conveyed to the lower part of the take-up reel. In a metal foil rolling mill in which the spool is shared by the unwinding reel and the take-up reel, a spool lifting means that raises the spool up to the reel causes the spool to fall from near the rolling mill to the lower part of the rolling roll and the lower part of the spool transporting path of the spool transporting means. The dust chute is provided with a dust chute which, when closed, opens the spool conveying path of the spool conveying means and which also opens the spool conveying path of the spool conveying means when closed. It has an opening/closing part that prevents dust from falling into the path, closes the spool transport path of the spool transport means when opened, and guides the dust to the dust collection means.

In addition, as a second means, the present invention provides a method for stacking metal foils wound around each spool attached to a plurality of unwinding reels and rolling them by introducing them into a rolling roll, and rolling the stacked and rolled metal foils. A metal foil rolling machine that winds up a spool on a spool attached to a take-up reel, the spool lowering means lowering the spool of each unwinding reel, and the lowered spool passing through the lower part of the rolling roll to the lower part of the take-up reel. In a metal foil rolling machine where the spool is shared between the unwinding reel and the take-up reel, rolling At the bottom of the roll and at the bottom of the spool conveying path of the spool conveying means, there is provided a dust collecting means for collecting dust falling from the vicinity of the rolling roll, and a dust chute for guiding the dust to the dust collecting means. , the dust chute has a spool conveying path of the spool conveying means when closed and prevents dust from falling into the path; when opened, the dust chute closes the spool conveying path of the spool conveying means and a dust collecting means. It has an opening/closing part that guides the dust to the dust chute, and further has a first stopper that holds the spool between the spool lowering means and the dust chute in the spool conveyance path of the spool conveyance means. A second stopper for holding the spool is provided between the dust chute and the spool lifting means.

(Function) While the metal foil 7 is being rolled by the rolling roll 2, the opening/closing part 21 of the dust chute 19 is opened to guide dust such as scrap and roll coolant oil falling from the rolling roll 2 side through the dust chute 19. , to the dust collecting means 16, and the path of the spool conveying means 10 is closed.

When handling the spool, the opening/closing part 21 of the dust shoe eye 9 is closed, and the spool 5 of the unwinding reel 4 is lowered onto the path of the spool conveying means 10 by the spool lower means 12, passing under the rolling roll 2. It is transferred to the lower part of the take-up reel 8. Then, the spool 5 is mounted on the take-up reel 8 by the spool lifting means 15. At this time, since the opening/closing part 2 is closed, the spool 5 will not get wet with oil.

When there are a plurality of unwinding reels 4 and a plurality of metal foils are stacked and rolled, the first unwinding reel 4 is

Reference numeral 15 denotes a spool lifting means for lifting the spools 5 conveyed to the lower part of the take-up reel 8 one by one to the take-up reel 8, and is constituted by a belt wrapper. 16 is rolling roll 2
A dust collection means that collects dust such as aluminum foil scraps and roll coolant oil droplets that fall from
It is installed below the rolling roll 2 and below the spool conveying path of the spool conveying means 10. The dust collecting means 16 is connected to a wire mesh conveyor 17 that transports the scraps from the drive side of the rolling mill to the work side (in the thickness direction of the page in FIG. 1), and the scraps are conveyed by the wire mesh conveyor 17. The oil pan 18 receives oil dripping downward from the oil pan 18. Reference numeral 19 denotes a dust chute that guides dust falling from the vicinity of the rolling mill to the dust collecting means 16, and is arranged between a pair of rectangular fixed plates 20 arranged on the inlet side and the outlet side, and between the fixed plates 20. It has an opening/closing part 21. The opening/closing part 21 is pivotally supported by a pivot 22 at the lower inner end of each fixed plate 20, and is connected to the cylinder 2.
It has a pair of rectangular opening/closing plates 24 which are opened and closed by the spool transport means 10. When closed, the spool transport path of the spool transport means 10 is opened and dust is prevented from falling into the path, and when opened, the spool transport means 10 is opened and closed. The spool conveyance path is closed and the dust is guided to the dust collection means 16. 25 is a first stopper, 26 is a second stopper,
The first stopper 25 is provided between the spool lowering means 12 and the dust chute 19 on the spool conveying path of the spool conveying means 10, and the second stopper 26 is provided between the dust chute 19 on the spool conveying path of the spool conveying means 10 and the spool rising. and the means 15. and,
These stops 25, 26 are both pivoted about pivots 29, 30 by the operation of cylinders 27, 28, and are adapted to hold the spool 5 on the spool transport path.

Next, the operation will be explained. When rolling aluminum foil, the entry side 2
Two sheets of aluminum foil 7 unwound from each coil 6 of a spool 5 mounted on an unwinding reel 4 are introduced into a rolling roll 2 in a vertically stacked state and rolled. Then, the stacked and rolled aluminum foil 7 is sequentially wound into a coil on a spool 5 attached to a take-up reel 8.

When two sheets of aluminum foil 7 are stacked and rolled in this way, the amount on the take-up reel 8 is completely wound by half the amount on the unwinding reel 4, as shown in FIG.

Therefore, when the spool 5 is shared by the unwinding reel 4 and the take-up reel 8, its handling is performed as follows. First, when the take-up reel 8 side is completely wound as shown in FIG. (See Figure 3). Then, this spool 5d is moved to the spool lifting means 15.
After the aluminum foil 7 is mounted on the take-up reel 8, rolling is started again and the rolled aluminum foil 7 is wound up. During this rolling, the pair of opening/closing plates 24 of the opening/closing part 21 of the dust chute 19
is in a downwardly open state and closes the spool conveyance path. Therefore, dust such as scraps and oil droplets of oil coolant falling from the rolling roll 2 side is guided onto the wire mesh conveyor 17 of the dust collecting means 16 by the fixing plate 20 and opening/closing plate 24 of the dust chute 19, and then Scrap is conveyed by a wire mesh conveyor 17, and oil is collected in an oil pan 18.

The two rewind reels 4 become empty almost simultaneously. When both rewind reels 4 are empty, the spools 5a and 5d are lowered onto the spool conveying means 10 by the respective spool lowering means 12 and held by the first stopper 25, as shown in FIG. The spool 5d on which the metal foil has been wound is removed from the take-up reel 8. Next, as shown in FIG.

o, it is conveyed while being rolled toward the second stopper 26, and is held by the second stopper 26. And the second
The spool 26 is released and, as shown in FIG. do. Subsequently, the spool 5b on the spool lifting means 15 is raised and attached to the take-up reel 8, and the opening/closing plate 24 of the dust chute 19 is lowered to open the opening/closing part 21. In addition, each unwinding reel 4 has another new spool 5 wound with a coil of aluminum foil.
Attach e and 5f, respectively.

According to the configuration of this embodiment, since dust such as scrap can be collected by the dust collecting means 16 at the lower part of the rolling mill, it can be removed efficiently and the work of two operators can be reduced. Furthermore, since the spool 5 can be handled via the lower part of the rolling mill, the spool 5 can be transported over the shortest distance. Moreover, there is a dust chute 19 at the bottom of the rolling roll 2, and the dust chute 19 is connected to the opening/closing part 21.
Therefore, when the spool 5 passes under the rolling roll 2, it does not get wet with roll coolant oil, and the work of the operator can be reduced in this respect as well. Furthermore, the opening/closing part 21
During rolling, the foil is opened so as to close the path of the spool conveying means 10, so that the fume rising from below the rolling mill can be shielded, and high-quality foil can be rolled without getting the winding coil wet with fume. Furthermore, since the dust processing equipment and spool handling equipment are simplified, it can be implemented at low cost and the working environment for the operator can be improved. Moreover, idle time is reduced and production efficiency is increased.

In the embodiment, the number of rewinding reels 4 is two, but it may be one, or three or more.

When there is only one rewind reel 4, the stopper 25.
It is also possible to omit 26.

The rolling mill is not limited to use for aluminum foil, but may be used for other types of copper foil.
