Description

Slitter device for metal plates capable of film laminating {Slitter Device of Metal Panel having Function of Film Laminating}

This invention relates to a slitter device for metal sheets, and more specifically, to a slitter device for producing narrow sheets by cutting long sheets along the longitudinal direction.

A slitter device is used as a device to cut metal sheets supplied from manufacturers and process them into sheets of the required width.

As a slitting device, Korean Patent Publication No. 10-1215671 (Document 1) discloses a device called "a slitter in which a cutter for a slitter and a buffer ring are coupled to a hydraulic expansion shaft."

Manufacturers of metal sheets process metal ingots to manufacture long, elongated sheets and supply them by winding them in roll form.

Processing companies that process metal sheets supplied from manufacturers into the required width unwind and flatten the metal sheets from the roll of metal sheets supplied from the manufacturer, then cut the metal sheets along the length direction to have the required width. It is wound again into a roll and transported to the place of demand.

Depending on the product to be manufactured from a metal sheet, the quality of the product may be adversely affected if the surface of the metal sheet supplied after being cut and wound by a processing company is contaminated with foreign substances or scratches occur.

Therefore, in the case of metal sheets that require high quality, processing companies slit the metal sheets, wind them on a roll, and package them to prevent foreign substances from penetrating, but the surface is damaged due to friction between the metal sheets wound together. This occurs and foreign substances may penetrate between the metal plates during the packaging process.

Document 1: Republic of Korea Patent Publication No. 10-1215671

The purpose of this invention is to provide a slitter device that cuts a long metal plate along the longitudinal direction, manufactures it into a narrow plate, and winds it in a roll.

Specifically, this invention involves unwinding a metal sheet supplied in a roll form, cutting it in the longitudinal direction, processing it to be narrow, and winding the processed sheet back into a roll, while protecting the surface of the metal sheet from contamination or damage. The aim is to provide a slitting device.

The problem to be solved by this invention described above is achieved by the slitter device according to this invention, which cuts a metal sheet along the longitudinal direction and winds it into a roll shape.

The slitter device of this invention is,

A slitter that cuts a metal panel in parallel in the longitudinal direction to form a metal panel with a width smaller than that when wound on an uncoiler;

A recoiler that winds the metal panel cut by the slitter into a coil shape; and

A film supply mechanism that supplies synthetic resin film to the coiler so that the synthetic resin film is laminated between metal panels wound on the recoiler.

It is composed including,

The metal panels cut from the slitter are fed into the recoiler parallel to each other and wound coaxially, and the film supply mechanism is such that a film with a width less than the width of the cut metal panels is placed between the cut metal panels and together with the metal panels. It is supplied to be wound on the recoiler.

In the slitter device according to this invention, narrowly cut metal panels are wound around a recoiler and a film is placed between the metal panels, so the surface of the wound metal panel is covered and protected by the film, thereby protecting it during the packaging process. The surface of the metal panel is not damaged or contaminated during the transport process.

In particular, the process of covering the surface of the metal panel with a film is not a separate process, but is carried out along with the process of winding the metal panel on a recoiler after slitting it, so the process is simple and the cost of covering the film is minimal. , contamination of metal panels is minimized.

As an additional feature of this invention, in the slitter device of this invention,

The film supply mechanism may be arranged in a direction opposite to the uncoiler, leveler, and slitter with the recoiler in between, and may be configured to supply a non-adhesive film to the recoiler in the direction opposite to the flow direction of the metal panel.

According to this configuration, the film supply mechanism is installed at a point past the end of the flow direction of the metal panel in the slitter device that has been used conventionally, without changing or rearranging the various mechanisms that make up the existing slitter device. The slitter device of this invention can be configured by adding a film feeding mechanism.

In a typical slitter device, the metal sheet is supplied in the form of a coil, and uncoiling of the metal sheet and flattening at the leveler are involved, so various equipment and mechanisms, from the uncoiler to the slitter, are used in the direction of transport of the metal sheet. are arranged in a line.

According to an additional feature of the invention, the film supply mechanism is arranged in the opposite direction from the slitter to supply the film to the recoiler, eliminating the need for modification or rearrangement of existing equipment.

In addition, since the film is supplied to the recoiler and wound together with the metal sheet while the slitted metal sheet is being wound around the recoiler, adhesion must be given to the film so that the film can be attached to the metal sheet during transportation of the metal sheet, or the film can be attached to the metal sheet. It is possible to use a non-adhesive film without the need to apply adhesive or adhesive.

Therefore, the process of applying an adhesive to provide adhesion is omitted, and there is no risk of the adhesive remaining on the surface of the metal plate and contaminating the metal plate.

In particular, when slitting a metal sheet with a film attached, residue from cutting the film during slitting does not contaminate the metal sheet or deform the film during the process.

Additionally, in a slitter device equipped with the additional features of this invention,

In the film supply mechanism, a plurality of rolls of film are mounted side by side on a single rotating axis at intervals from each other, and the film is released from the film rolls and wound on a recoiler along with the cut metal panels, stacking them between the metal panels. It can be composed of:

According to this configuration, a film is supplied to each roll of a plurality of metal plates that are cut into plural pieces in the slitter and wound together in a recoiler. However, since the supply of the film is done by a single rotating shaft, the equipment configuration is very simple. The control becomes easy.

Additionally, in a slitter device equipped with the additional features of this invention,

In the film supply mechanism, the rotating axis on which the film roll is mounted can rotate freely, and as the film is laminated between metal panels wound on the recoiler and wound on the recoiler, the axis on which the film roll is mounted rotates to release the film. can do.

In this configuration, a brake is provided that provides resistance to free rotation of the rotating shaft of the film supply mechanism, and the rotating shaft of the film supply mechanism and the brake can be configured to be provided with gears that mesh with each other.

Therefore, since the rotation axis of the film supply mechanism rotates in synchronization with the rotation of the recoiler, there is no need to synchronize the supply speed of the film with the supply speed of the metal sheet wound on the recoiler. In particular, an appropriate tension force is applied to the film and the metal sheet and the metal sheet are connected to each other. Since they are wound together, close contact between the film and the metal plate is achieved.

As a further feature of this invention,

The film supply mechanism includes a movable frame on which a rotating shaft is mounted, a fixed frame fixed to the ground, and a moving mechanism installed on the fixed frame to move the movable frame in a direction perpendicular to the film supply direction. The movable frame is moved by the moving mechanism. By doing this, the film supplied to the recoiler can be configured to be aligned with the metal plate.

Accordingly, even if the installation of the film roll in the film supply mechanism is not performed precisely, the film and the metal sheet can be aligned by adjusting the position of the movable frame after installing the film roll.

As a further feature of the invention, in the slitter device according to the invention,

The recoiler includes a main shaft configured to expand and contract in diameter, and

It operates between a pressurized state rotating parallel to the main shaft and a spaced state spaced apart from the main shaft, and may be configured to include a pressing shaft with a pressing surface that presses a metal plate wound around the main shaft in a pressurized state.

In addition, in the slitter device according to the present invention, the film supply mechanism is provided with a plurality of rotation axes on which film rolls are mounted, the plurality of rotation axes are arranged parallel to each other, and all the film rolls mounted on one rotation shaft are used. It can be configured so that the roll of film mounted on another rotating shaft is supplied to the recoiler.

According to this configuration, when the film roll mounted on one rotating shaft is exhausted, the film roll mounted on another rotating shaft can be used without replacing the film roll, thereby minimizing process interruption.

A first pinch roll (13) is provided to apply the traction force for transport.

The first looper (12) is provided as a space where the metal plate released from the uncoiler (11) can be placed in a downward state due to its own weight, and the first pinch roll (13) has two rollers facing each other. It consists of placing and rotating the metal plate 1 placed between them and pressurizing and transporting it downstream.

The leveler 20 is composed of an upper roll set and a lower roll set in which a plurality of rollers are arranged side by side, and the metal plate 1 alternately penetrates between the rollers forming the upper roll set and the lower roll set to provide repetitive and directional movement. It is processed flat by receiving alternating bending stress.

The tip of the metal plate 1 that is released from the uncoiler 11 and passes through the leveler 20 is cut and removed at the entry cutter 31 located downstream of the leveler 20. Since the metal sheet manufactured by the manufacturer by rolling, etc. has an uneven structure and defects at the tip, the tip is removed at the entry cutter 31.

The entry cutter 31 is composed of an upper cutting blade and a lower cutting blade extending in the width direction of the metal sheet 1, and cuts along the width direction of the metal sheet 1.

The operation of the slitter device having the above configuration will be described.

First, a coil of aluminum sheet with a width of 1200 mm and a thickness of 2.0 mm was prepared as the metal sheet (1) to be slitted and mounted on the uncoiler (11).

The aluminum sheet (1) is pulled out from the coil of aluminum sheet mounted on the uncoiler (10), the tip is engaged with the first pinch roll (13), and the first pinch roll (13) is driven to rotate, thereby forming the uncoiler (10). From there, the aluminum plate (1) proceeds downstream.

The aluminum sheet (1) passes through the leveler (20), is processed flat, and its tip is cut by the entry cutter (31), and then passes through the embossing roll (32). If there is no pattern or character to be embossed on the aluminum plate 1, the rollers forming the embossing roll 32 are spaced apart from each other and do not operate.

The aluminum sheet 1 that has passed the embossing roll 32 passes through the slitter mechanism 40. The slitter mechanism is provided with three cutting blades (43, 44) on the upper rotating shaft (41) and lower rotating shaft (43), so that the aluminum sheet (1) is divided into four pieces with a width of 300 mm and transported downstream. .

The cut aluminum plate 2 receives a traction force from the second pinch roll 52, moves downstream, and is wound around the main shaft 61 of the recoiler 60 through the adjustment roller set 54.

In the recoiler 60, the pressing shaft 63 is spaced apart from the main shaft 61 by the rotation of the pressing mechanism 65 by the expansion of the pneumatic cylinder 654, and in this state, the aluminum plate 2 is The tip is coupled to the main shaft (61).

In addition, the first axis 71 of the film supply mechanism 70 is separated from the post 752, four film rolls 4 are mounted, and then again mounted on the post 752, and each film roll 4 After unwinding the film (3) and passing it through the first guide roller (73), the tip is attached to the aluminum plate (2).

As the film 3, a polyethylene film with a thickness of 50 μm and a width of 300 mm, which is the same width as the cut aluminum plate 2, was used.

In this embodiment, aluminum plates 1 and 2 of a specific thickness and width and a film 3 of a specific material and thickness are used, but specifications such as the material and thickness of the metal plate, the required width, and the thickness and material of the film are It may change depending on the specifications required by the customer.

Meanwhile, in the slitting device of this embodiment, a film 3 of the same width as the slitted metal sheet 2 is used so that the entire surface of the metal sheet is covered with the film, but the slitted metal sheet 2 is used as required by the customer. A film having a width smaller than the width of the metal plate can also be used.

For example, when processing such as welding is performed on the width-direction end of a slitted metal sheet at the point of demand, a film with a narrower width than the metal sheet is used, so the film is not laminated on both ends of the metal sheet, so the entire film is separated from the metal sheet. Work such as welding is possible without separation.

The aluminum plate 2 was wound from the upper side of the main shaft 61, and the film 3 was wound from the lower side of the main shaft 61.

In this way, as the narrowly slit aluminum sheet 2 is wound around the main shaft 61, the film 3 is also wound, and the film 3 is placed between the wound aluminum sheets 2.

Accordingly, a non-adhesive film is placed between the aluminum plates 2 to protect the surface of the aluminum plates 2, without applying an adhesive to the aluminum plates 2 or using an adhesive film.

When the aluminum sheet 2 of the length required by the customer is cut and transported by the slitter mechanism 60, the pull-out cutter 53 cuts the aluminum sheet 2 at the corresponding length position.

When all of the aluminum sheets (2) with the rear end cut off are wound around the main shaft (61), the rotation of the main axis (61) is stopped and the film (3) is cut, and then the film (3) is rolled together on the roll ( 4) is pulled out from the main shaft (61).

If the extension piece 613 of the main shaft is contracted prior to withdrawal, a gap is created between the expansion piece 613 and the inner diameter of the aluminum sheet roll 4, making it easy to pull the aluminum sheet roll 4 from the main shaft 61. I do it.

The rolls (4) of drawn aluminum sheets are transported after being packed with packaging materials to prevent contamination and damage.

A roll 4 of the same film as that of the first axis 71 is mounted on the second axis 72 of the film supply mechanism, and when the roll 4 of the film wound on the first axis 71 is exhausted, Unwind the film (3) from the second shaft (72) and sequentially pass the second guide roller (74) and the first guide roller (73) to the aluminum plate (2) wound on the main shaft (61) of the recoiler. It is attached or wound up by attaching it to the rear end of the film (3) that has been released from the first axis (71).

Meanwhile, in this embodiment, the film supply mechanism 70 is provided with two axes 71 and 72 for mounting and unwinding the roll 4 of the film, but only one axis is provided and one axis is used when the film runs out. The film roll (4) can be wound again on the axis and work can be resumed.

As described above, the configuration and operation of one embodiment of this invention have been described. This invention is not limited to the configuration of this embodiment, and various changes and additions of components are possible within the scope set forth in the claims.
