According to one embodiment, a transfer apparatus includes a coating part for coating an uncured resin on a substrate, a substrate installation part for positioning and installing the substrate integrally, a mold installation part for installing a sheet-like mold, a transfer roller for transferring a fine transfer pattern formed on the mold to the resin coated on the substrate, and a plasma unit for cleaning the mold by irradiating plasma to the mold peeled off from the resin after transferring. After cleaning by the plasma using the plasma unit, the cleaned mold is used again for transferring of the transfer pattern.

Transfer apparatus

A transfer apparatus includes a rolled web mold installation part for installing a rolled web mold around which the mold is wound, a transfer roller for winding the mold fed out from the rolled web mold, a winding roll for winding up the mold, a winding roll installation part for installing the winding roll therein, and a mold installation assisting part for guiding the mold fed out from the rolled web mold up to the winding roll while suppressing an occurrence of wrinkles in the mold fed out from the rolled web mold.

Transfer apparatus and transfer method

According to one embodiment, a transfer apparatus includes a transfer roller which supports a mold and transfers a fine transfer pattern formed on the mold to a resin coated on a substrate installed in a substrate installation part with movement of the transfer roller and a transfer roller guide part for guiding the transfer roller when the mold is pressed against the resin coated on the substrate installed in the substrate installation part by the movement of the transfer roller.

A transfer device that transfers a fine transfer pattern formed on a master mold to a molded material, includes a first transfer unit that transfers the fine transfer pattern formed on the master mold to a replica mold made from a material that transmits light; and a second transfer unit that transfers a fine transfer pattern formed on the replica mold by the first transfer unit to the molded material.

Transfer device, molded material and transfer method

A sheet-shaped mold position detection devicefor conveying and positioning a sheet-shaped mold M on which a fine transfer pattern Mis formed. The sheet-shaped mold position dejection deviceincludes a sheet-shaped mold position detectorthat detects a predetermined region of the sheet-shaped mold M by detecting transmittance of light in the sheet-shaped mold M.

Sheet-shaped mold position detection device, transfer device and transfer method

A transfer device includes a holding body that holds a molded material; a first roller that holds, together with the holding body, a wound mold and the molded material held by the holding body so as to carry out a transfer, and rotates about a central axis to move with respect to the holding body; and a second roller on which the mold extending from the first roller is wound in a direction away from the molded material held by the holding body, the second roller rotating about a central axis to relatively move together with the first roller.

Transfer device and molded material

A transfer systemcomprising: a conveying/positioning deviceconfigured to convey and position a flat sheet-shaped mold MA in a predetermined direction, on which a fine transfer pattern Mis formed; a transfer deviceconfigured to transfer the fine transfer pattern Mto a molding target W, the transfer devicebeing provided on an upstream side in the conveying direction of the sheet-shaped mold MA; and a peeling deviceconfigured to peel off the sheet-shaped mold MA and the molding target from those mutually clinging to each other, after the transfer by the transfer deviceis performed and the conveyance by the conveying/positioning deviceis performed, the peeling devicebeing provided on a downstream side in the conveying direction of the sheet-shaped mold MA.

Transfer system and transfer method

A demolding device detaches a sheet-shaped mold from a molded product. The demolding device includes a molded product holder placed in a location different from a transfer device. The molded product holder is constructed and arranged to hold the molded product while being adhered to a first region of the mold. A detaching roller on which the mold is wound is movably provided above the molded product holder in an extending direction of the mold to roll up and detach the mold from the molded product.

Demolding device

A transfer devicetransfers a fine transfer pattern Mformed on a mold M to a molding target W. The transfer device includes: a base memberincluding a press bodya moving memberincluding a molding target placing bodythat sandwiches and presses the mold M and the molding target W in cooperation with the press body, and is provided on the base memberso that the molding target placing bodycan move; and a moving body supporting bodythat includes a guide portion, and is engaged with and provided integrally on the base memberonly in a region of the base memberelastically deformed very slightly by reaction force when the press is performed, the region being a region where a flexure angle becomes substantially '0'.

Transfer device

A conveying/positioning device includes: a unused-mold placing devicethat places a rolled mold MB of a sheet-shaped mold M thereon; a mold rolling-up devicethat rolls up the flat sheet-shaped mold MA supplied from the unused-mold placing device; and a tension maintaining device that constantly maintains a tension of the flat sheet-shaped mold even if a form of the flat sheet-shaped mold is changed when the peeling is performed.

Sheet-shaped mold conveying/positioning device

Shape information of a molded article is used to determine cross sectional information. Injection speed pattern data is generated based on parameter information such as the cross sectional area of a barrel cylinder, the filling time interval, the injection stroke, etc., and the generated cross sectional information. The injection speed pattern data is used to control the injection speed of the injection screw.

Apparatus for generating an injection speed pattern

Method and apparatus for generating an injection speed pattern

A barrel has an injection nozzle at the forward end, and an injection screw inside, and heaters in the outer circumference. The barrel injects the molten resin from the injection nozzle at the forward end by the rotation of the injection screw. In the barrel, the temperatures of each parts are controlled by a temperature control section. A controller sets a shift minus temperature to uniformly lower the temperature of the parts, and a shift absolute temperature to lower the temperatures of the parts to a predetermined temperature. An operation panel section selects the shift minus temperature or shift absolute temperature to lower the temperatures of the parts. The temperature control section lowers the temperatures of the parts of the barrel by using the temperature selected when the injection molding machine is temporarily stopped.
