Description

slitter apparatus

The present invention relates to a slitter device capable of improving processing precision.

DESCRIPTION OF RELATED ART In recent years, a film is used for various uses, such as an optical film, a conductive film, a protective film, a conductive film, the film for distribution boards, and a transfer film.

Before winding the long film in the production process of the film, a step of cutting the edge of the film or a step of cutting a wide film into a plurality of narrow widths along a desired width are performed.

Although a cutting blade is widely used for cutting|disconnecting a film, there exist the following problems.

(1) The film has a long length, and particularly when the film is a laminated film, the cutting resistance and frictional force with respect to the cutting blade are large. For this reason, there is a problem that the cutting blade comes off, so-called chipping, and the cutting blade wears out. Thereby, a running cost increases by replacement|exchange of a cutting blade.

(2) Film powder generate|occur|produces by cut|disconnecting a film. Moreover, when cut|disconnecting a coating film or laminated|multilayer film, resin powder arises by cut|disconnecting a contact bonding layer or an adhesion layer with a film. When these foreign substances adhere to the film after cutting, quality will fall and a yield will fall.

(3) When cut|disconnecting the laminated|multilayer film on which the protective film was laminated|stacked, since peeling of a protective film necessarily arises, the single-sided grinding|polishing of a laminated|multilayer film becomes indispensable after cutting|disconnection. Since the corresponding process is required, the manufacturing cost is increased.

(4) In the cutting of a crack-prone film, particularly a laminated polarizing film, a notch is easily generated on the cut surface of the PVA (polyvinyl alcohol) layer, so that a crack or rupture occurs very easily in the laminated polarizing film.

Specifically, the nozzle 364 is disposed to face a portion where the cutter 120 and the film f of the cutting assembly 100 meet, and the cutting portion of the film may be locally cooled.

The film may be stretched or contracted according to the temperature according to the thermal expansion coefficient of the material. If the slitter device is continuously operated, the film is stretched due to the increase in the temperature inside the factory, and when cutting the stretched film, there is a problem that processing errors are continuously generated.

The slitter device according to this embodiment can locally cool the film through the cooling air sprayed from the nozzle 364, and through this, the film is contracted by the cooling air. It is possible to improve the processing precision of the film by minimizing the error.

Since the refrigerant evaporated from the evaporator 340 is supplied to the accumulator 380, the temperature may be low, and some refrigerant may be maintained in a liquid state due to the low temperature.

When the accumulator 380 is disposed in the 1-1 housing space 321 , the high temperature is transmitted from the condenser 320 to vaporize the stored liquid refrigerant. In particular, since the condenser 320 and the accumulator 380 are disposed together in the first housing 325 , the low refrigerant temperature of the accumulator 380 can improve the condensation efficiency of the condenser 320 , so that mutually effective A refrigerant cycle can be formed.

The controller of the slitter device according to the present embodiment may detect the temperature of the first temperature sensor 201 to determine the operation of the cold air supply device 300 . For example, when the temperature around the supply roller 20 is equal to or higher than the first temperature value, it is determined that the thermal expansion coefficient of the film is excessive, and the cold air supply device 300 is operated to provide cold air to the film. ( first condition)

In addition, the control unit of the slitter device according to the present embodiment detects the temperature of the second temperature sensor 202 to determine whether the operation of the cold air supply device 300 continues. For example, when the temperature detected by the second temperature sensor 202 is less than or equal to the second temperature value, it is determined that the temperature of the cutting assembly 100 is too low, and the cold air supply device 300 can be stopped. . (Second condition)

Also, the controller of the slitter device according to the present embodiment may control the operation of the cold air supply device 300 through a temperature difference between the first temperature sensor 201 and the third temperature sensor 203 .

When "the first temperature value - the third temperature sensor sensed temperature ≥ the first temperature difference", it is determined that the temperature of the supply roller 20 is higher than the ambient temperature, and the cold air supply device 300 may be operated. (Third condition) The first temperature difference may be a preset value.

Conversely, in the case of "the first temperature value - the third temperature sensor sensing temperature < the first temperature difference", it is determined that the temperature of the supply roller 20 is lower than the ambient temperature, and the cold air supply device 300 can be stopped. . (4th condition)

Therefore, when both the first condition and the third condition are satisfied, it is preferable to operate the cold air supply device 300 to improve processing precision, and when both the second condition and the fourth condition are satisfied, the cold air supply device 300 It is preferable to stop (300) in order to improve processing precision.

The fourth temperature sensor 204 senses the temperature of the 1-2 housing space 322 , and the fifth temperature sensor 205 senses the temperature of the 2-2 housing space 342 .

In summer when the outside temperature is very high, the condensation efficiency of the refrigerant may be low.

When the temperature sensed by the fourth temperature sensor 204 exceeds the fourth temperature value, the valve 363' of the housing hose assembly 305 is opened to cool the first housing 325, and the Through this, it is possible to improve the efficiency of the refrigerant cycle of the cold air supply device 300 .

In particular, the housing hose assembly 305 supplies cold air to the 1-1 housing space 321 to lower the temperature of the air flowing into the condenser 320, thereby improving the condensation efficiency.

When the temperature sensed by the fifth temperature sensor 205 exceeds the fifth temperature value, it is determined that the refrigerant cycle of the cold air supply device 300 is abnormal, and an error message is output. When the fifth temperature value is exceeded, it can be expected that the refrigerant is insufficient, the refrigerant pipe is damaged, or the cooling fan 350 is damaged.

6 is a schematic side view of a thermostat disposed on the cutting assembly of FIG. 3 ;

Since the cold air supply device 300 according to the present embodiment controls the temperature through convection, a delay occurs due to heat transfer.

The thermostat 400 according to the present embodiment can control the temperature of the cutter 120 more precisely by adjusting the temperature of the cutting assembly 100 through heat conduction.

The thermostat 400 is disposed on the cutting assembly 100 .

In the present embodiment, the thermostat 400 includes a thermoelectric module and is disposed on the first body extension 141 in which the second temperature sensor 202 is disposed.

The first body extension part 141 includes a first one side 441 on which the cutting wheel 130 is assembled, a first other side surface 442b on which the second temperature sensor 202 is disposed, and the It includes a first lower surface 443 disposed to face the film f, and a first upper surface 444 connecting upper ends of the one side 441 and the other side 442 .

The second body extension portion 142 includes a second one side 451 forming a continuous surface with the one side 441, and a second other side surface ( 452), a second rear surface 456 connecting the second one side 451 and the second other side 452, and facing the second cutter body 150, and the second one side surface ( 451 ) and the second other side surface 452 , the second front surface 455 is disposed to intersect the first upper side surface 444 and is connected to the first upper side surface 444 .

The thermostat 400 is installed in close contact with the rear surface 456 of the second body extension part 142 .

The thermoelectric device 400 includes a thermoelectric element 410 that generates heat or heat from the front side by the Peltier effect by the applied power and generates heat or endothermic heat opposite to the front side at the rear side, and the thermoelectric element 410 ) includes a cooling fin 420 coupled to the rear surface.

The thermoelectric element 410 uses heat absorption or heat generated by the Peltier effect, and in particular, cooling using this is called electronic cooling.

The Peltier effect is a phenomenon in which two types of metal ends are connected, and when a current flows through it, one terminal absorbs heat and the other terminal generates heat depending on the direction of the current.

If a semiconductor such as bismuth or tellurium with a different electrical conduction method is used instead of the two types of metal, a Peltier device with high-efficiency endothermic and exothermic action can be obtained.

Since the structure and operation principle of the thermoelectric element 410 are common to those skilled in the art, detailed descriptions thereof will be omitted.

The front surface of the thermoelectric element 410 is in close contact with the rear surface 456 of the second body extension part 142, and heat absorption or heat generated on the front surface of the thermoelectric element 410 is the second body extension through heat conduction. directly to the unit 142 .

The cooling fins 420 are coupled to the rear surface of the thermoelectric element 410 .

The tilting shaft 145 is disposed within the height of the thermoelectric element 410 . The upper distance D1 and the lower distance D2 of the cooling fins 420 are formed equally with respect to the tilting axis 145 . it is preferable

This is a design in consideration of contact with the second cutter body 150 when the first cutter body 140 is tilted.

As in the present embodiment, when the upper distance D1 and the lower distance D2 are the same, when the first cutter body 140 is tilted, the upper and lower sides of the cooling fins 420 are located at the second cutter body 150 . ) and the contact angle can be formed to be the same.

The upper end of the cooling fin 420 is formed with an upper inclined surface 421 inclined from the front upper side to the rear lower side, and the lower end has a lower inclined surface 422 inclined from the front lower side to the rear upper side.

When the first cutter body 410 is tilted, the upper inclined surface 421 or the lower inclined surface 422 may be supported by the first moving body part 151, and the first cutter body 410 rotates. angle can be limited.

When the cooling fins 420 are supported by the first moving body unit 151 , heat absorption and heat generated by the cooling fins 420 may be conducted and heat may be transferred to the first moving body unit 151 .

The control unit of the slitter device may determine whether the thermostat 400 is operated and the direction in which the current is applied through the temperature sensed by the second temperature sensor 202 .

For example, when the second condition (the temperature of the cutting assembly is less than or equal to the second temperature value), the temperature of the first cutter body 140 can be actively increased by applying a current to the thermostat 400 , , the cutter 120 can be maintained at an appropriate temperature.

Conversely, when the temperature of the first cutter body 140 sensed by the second temperature sensor 202 is equal to or greater than the set value, the temperature of the first cutter body 140 is actively increased by applying a current to the thermostat 400 in the opposite direction. can be lowered to

In this way, the slitter device according to the present embodiment improves the processing precision in the cut portion of the film through the cold air supply device 300 , and maintains the cutting assembly 100 at an appropriate temperature through the constant temperature device 400 . there are advantages to
