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 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

A work setting apparatus includes a lower table, an upper table, and a work holding unitprovided with a plurality of work holderseach having an adhesive to hold a work. A work setting method sets a second work Wheld by the work holdersonto a first work Wset on the lower table. A work holder removing method removes the work holdersfrom the second work Wset on the first work Wby vibrating the first and second works Wand Won the lower table

Work setting apparatus, work setting method, and work holder removing method

An object of the present invention is to facilitate the release of a formed product from a die. A lower die is formed of a die plate, a plurality of cores, a cavity die and a slide plate. In the cavity die, a plurality of first opening portions are formed at the upper side and a second opening portion is formed at the lower surface side. Each of the first opening portion communicates the second opening portion. A core is placed each of the first opening portions. The slide plate is fitted in the second opening portion and supports each core from the lower side. A through-hole is formed in the die plate. The tip of an ejector pin is inserted into the through-hole. The ejector pin is installed in a lower shaft of the machine.
