A cleaning station for removing surface impurities from the surface of a cylindrical magnetic rotor having an axis; the cleaning station comprises: a seat for housing the magnetic rotor in a rotatable manner about its axis; a first pin having an axis parallel to the axis of the magnetic rotor when housed in the seat, wherein the first pin is rotatable about its axis and supports a roll of adhesive tape; a second pin having an axis parallel to the axis for the first pin; wherein the second pin receives an initial unwinding end of the roll of adhesive tape supported on the first pin and is rotatable about its axis to progressively wind the adhesive tape about its axis during unwinding from the first pin; a motorization for commanding the unwinding of the adhesive tape from the first pin and the winding of the adhesive tape on the second pin; a pusher device configured to press the adhesive tape as it passes from the first and to the second pin against the magnetic rotor housed in the seat so that by dragging, the motion of the adhesive tape commands the rotation of the magnetic rotor about its axis and the surface impurities on the magnetic rotor migrate from the magnetic rotor to the adhesive tape remaining attached on the adhesive of the adhesive tape. Main figure: FIG. 6

An apparatus for winding at least one strip of material is described, the apparatus comprises: a winding core rotatable about a rotation axis, configured to grip said strip and actuatable in rotation to drag the gripped strip and thus form a winding around the rotation axis from a portion of predetermined length of strip; and a feeding unit for feeding the strip of material to the winding core along a respective feed path extending from the feeding unit to the winding core; the apparatus further comprising an auxiliary drag device interposed between the feeding unit and the winding core, along the feed path, and configured to pull the strip of material from the feeding unit and push it towards the winding core, so as to assist the winding core in dragging the strip.

A winding apparatus winds up a belt-shaped electrode sheet including an active material and a belt-shaped separator sheet made of an insulating material, and includes: a rotatable winding core to which the electrode and sheets are fed at accelerating or decelerating speed, and around which the electrode sheet and the separator sheet are wound; a rotatable transfer roller that defines a transfer path of the electrode sheet and has an outer circumference face on which the electrode sheet is placed; and a swing motion suppressing guide disposed at a position immediately upstream of the transfer roller along the transfer path. The electrode sheet includes: an electrode main body on which the active material is applied; and tabs protruded from a width direction edge portion of the electrode main body and disposed at intervals along a longitudinal direction of the electrode main body.

Disclosed is an automatic electrode plate leading apparatus for secondary batteries which, when an arm descends, vacuum-adsorbs and grips a barcode part of a standby electrode plate and then rises in the state in which an EPC sensor and a replacement preparation core move backwards, a first roller moves right, a third roller descends and second rollers rise, automatically connects the electrode plate vacuum-adsorbed and gripped by the arm to the replacement preparation core in the state in which the first roller moves left, the second rollers descend, the third roller rises and the EPC sensor and the replacement preparation core move forwards. The automatic electrode plate leading apparatus includes a standby electrode plate (1), an EPC sensor (2), a first roller (3), second rollers (4), a third roller (6), the arm (8) rotated to rise or descend by an arm drive motor (11), and a replacement preparation core (7).

To prevent a support shaft from breaking during production and assembly. A transfer tool of the present invention is a transfer tool that allows a transfer tape fed out from a feed reel to be wound onto a take-up reel via a transfer head, and includes a rotation transmission means having a feed gear, a take-up gear, and an intermediate gear, that have a disc shape, and transmitting rotation of the feed reel to the take-up reel. The intermediate gear is rotatably supported by an intermediate support shaft, and the intermediate gear is provided with a stress relief means that relieves bending stress when the intermediate gear is attached to the intermediate support shaft.

The electrode driving apparatus is for driving an electrode that is coated with an active material, and includes a main base, a sub base spaced apart from and parallel to the main base, a shaft extending from the sub base toward the opposite side to the main base, an electrode driving roller that rotates about the shaft and is in contact with the electrode, and a position adjuster that is located between the main base and the sub base and regulates a gap between the main base and the sub base.

A winding unit includes a winding roller configured to wind up an elongated medium M that was transported, a cylindrical pressing member that extends along a rotation shaft of the winding roller and that is configured to press the medium M toward the winding roller at a position where the medium M is wound by the winding roller, a cylindrical winding guide member that extends along the rotation shaft of the winding roller, that has a fixed position with respect to the winding roller, and that is configured to guide the medium M to the winding roller before the medium is wound up by the winding roller, and arms that extend in a direction intersecting an extension direction of the pressing member and that are configured to support the pressing member, wherein the arms are configured to pivot about a central shaft of the winding guide member.

An image forming apparatus, comprises: a setting unit configured to set a divider region in a group of images that are continuously printed during feeding from a feeding apparatus in which a roll-shaped printing medium has been set, the divider region being for separating the roll-shaped printing medium into a plurality of rolls. The setting unit sets the divider region based on the number of rolls indicating the count of the plurality of rolls, the number of rolls being required in terms of a configuration of a post-processing device that executes post-processing with respect to the roll-shaped printing medium on which printing has been performed by the printing unit.

Proposed is a roll-to-roll manufacturing method of electrodes for secondary batteries including material supplying for supplying an electrode material from an unwinder, meander correcting for correcting meandering in a movement path of the electrode material, notching processing for forming an electrode tab shape by processing a tab fabrication area of the electrode material, cleaning the electrode material, vision inspection for determining whether the electrode material is of good quality, and electrode material winding for winding the electrode material with a rewinder.

An image forming apparatus, a control method of the image forming apparatus, and a storage medium can suppress occurrence of a wasteful operation and perform a rewinding operation of an optimal amount. To this end, after stop of printing by the image forming apparatus, a print status at print start is obtained, and a rewinding distance of a roll paper is set based on the obtained print status. Then, a paper conveyance unit performs rewinding conveyance (reverse rotation conveyance) based on the set rewinding distance.
