Description

Slitter device {SLITTER APPARATUS}

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

BACKGROUND OF THE INVENTION In recent years, films have been used in various applications such as optical films, conductive films, protective films, conductive films, films for power distribution boards, and transfer films.

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

Although cutting blades are widely used for film cutting, there are the following problems.

(1) The film is long, and especially when the film is a laminated film, the cutting resistance and frictional force against the cutting blade are large. For this reason, there is a problem that the cutting blade comes off, so-called chipping occurs, and the cutting blade wears out. Thereby, a running cost increases by the replacement of a cutting blade.

(2) Film powder is generated by cutting the film. Moreover, when cutting a coating film or laminated|multilayer film, resin powder arises by cutting an adhesive layer or an adhesive layer together with a film. When these foreign substances adhere to the film after cutting, the quality is lowered and the yield is lowered.

(3) When cutting the laminated film on which the protective film is laminated, peeling of the protective film will inevitably occur, so polishing the end face of the laminated film after cutting becomes indispensable. Since the corresponding process is required, the manufacturing cost is increased.

(4) Cracks or ruptures occur very easily in the laminated polarizing film because a notch (crack) is easily formed in the cut surface of the PVA (polyvinyl alcohol) layer in cutting a film prone to cracking, particularly in the case of cutting the laminated polarizing film.

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

The slitter device according to the present embodiment can locally cool the film through the cooling air sprayed from the nozzle 364, and through this, the film is shrunk by the cooling air, so it is processed by tearing at the cut surface of the film.

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

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

The first temperature sensor 201 may be disposed on a rotating shaft of the supply roller 20 .

The second temperature sensor 202 may be disposed on the first cutter body 140 or the second cutter body 150 . In this embodiment, the second temperature sensor 202 is disposed on the first body extension 141 assembled with the cutter 120 .

The third temperature sensor 203 may be disposed on the first body frame 11 or the second body frame 12 .

The fourth temperature sensor 205 preferably senses the temperature of the 2-2 housing space 342 in which the heat-exchanged air flows.

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 higher than the first temperature value, it is determined that the coefficient of thermal expansion of the film is excessive and the cold air supply device 300 is operated to provide cold air to the film. ( 1st condition)

In addition, the controller of the slitter device according to the present embodiment detects the temperature of the second temperature sensor 202 and determines whether the cold air supply device 300 continues to operate. For example, when the temperature sensed 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. . (Condition 2)

In addition, 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 .

In the case of "first temperature value - temperature sensed by the third temperature sensor ≥ 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 can be operated. (Third condition) The first temperature difference may be a preset value.

Conversely, when "first temperature value - third temperature sensor sensed temperature < 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. . (Condition 4)

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 is operated. Stopping 300 is desirable for improving processing accuracy.

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

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

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, which Through this, the efficiency of the refrigerant cycle of the cold air supply device 300 can be improved.

In particular, the housing hose assembly 305 supplies cold air to the 1-1st housing space 321 to lower the temperature of the air flowing into the condenser 320, thereby improving 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. If the temperature exceeds the fifth temperature value, a shortage of refrigerant, damage to the refrigerant pipe, or damage to the cooling fan 350 may be expected.

6 is a schematic side view of a thermostat disposed in 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 this embodiment can control the temperature of the cutter 120 more precisely by adjusting the temperature of the cutting assembly 100 through heat conduction.

The constant temperature device 400 is disposed on the cutting assembly 100 .

The thermoelectric element 410 uses endothermic or exothermic heat due to the Peltier effect, and in particular, cooling using this is referred to as electronic cooling.

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

If a semiconductor such as bismuth tellurium with a different electrical conduction method is used instead of the two types of metals, a Peltier device with highly efficient endothermic and exothermic action can be obtained.

Since the structure and operating principle of the thermoelectric element 410 are common to those skilled in the art, a detailed description 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 from the front surface of the thermoelectric element 410 is transmitted through the second body extension part 410 through heat conduction. directly to unit 142.

The cooling fin 420 is coupled to the rear surface of the thermoelectric element 410 .

The tilting shaft 145 is disposed within the height of the thermoelectric element 410 . It is preferable that the upper side distance D1 and the lower side distance D2 of the cooling fin 420 are identical with respect to the tilting shaft 145 .

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

When the upper distance D1 and the lower distance D2 are the same as in this embodiment, when the first cutter body 140 is tilted, the upper and lower sides of the cooling fin 420 are the second cutter body 150 ) and the contact angle can be formed 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 is formed with 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 can be supported by the first moving body 151, and the rotation of the first cutter body 410 angle can be limited.

When the cooling fin 420 is supported by the first moving body 151 , heat absorption and heat generation of the cooling fin 420 may be conducted to the first moving body 151 .

The control unit of the slitter device may determine whether the constant temperature device 400 is operating and the direction of current application through the temperature sensed by the second temperature sensor 202 .

For example, in the case of the second condition (the temperature of the cutting assembly is equal to or less than the second temperature value), the temperature of the first cutter body 140 can be actively increased by applying a current to the constant temperature device 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 higher than the set value, a current is applied to the constant temperature device 400 to positively increase the temperature of the first cutter body 140. can be lowered to

However, depending on the implementation, some elements of the plurality of transmission paths may be commonly used.

An analog beamforming circuit performs beamforming on an analog signal. To this end, the digital beamforming circuit multiplexes analog signals by beamforming weighting values. The beamformed weights are used to change the amplitude and phrase of the signal. More specifically, the analog beamforming circuit may be configured in various ways according to a connection structure between a plurality of transmission paths and an antenna.
