The component-feeding action causing one of the electric components of each unit to be fed to the component-supply portion of each unit with the component-feeding preparing action causing the feeding device to be prepared for the component feeding action.

Abstract: An apparatus for feeding an electric-component tape which includes a carrier tape having feed holes in its lengthwise direction and which holds electric components at a predetermined pitch in the lengthwise direction, the apparatus including a drive device, two pivotable members which are reciprocatively pivotable about a common axis line, a motion converting device which converts the motion of the drive device into the respective reciprocative pivotal motions of the two pivotable members, such that when one of the two pivotable members is pivoted in one of opposite directions about the common axis line, the other pivotable member is pivoted in the other direction and, vice versa, a feed member having projections projecting outward from its circulateable circumferential surface to engage the feed holes of the carrier tape, and two one-way transmitting devices one of which transmits the pivotal motion of the one pivotable member in the one direction, to the feed member, but does not transmit the pivotal motion

Abstract: A feeding mechanism for a forging machine includes a roller unit consisting of a pair of feeding rollers. Two rotating shafts are connected respectively and fixedly to the feeding rollers at an end portion, and to outer and inner driven gears at the other end portion. The inner and outer driven gears mesh with each other. A driving gear meshes with the inner driven gear, and rotates reciprocally within a predetermined angular range. The driving gear and the outer driven gear are sector gears. Each of the inner and outer driven gears is mounted on the corresponding rotating shaft by means of a unidirectional bearing so as to convert reciprocal rotation of the driving gear into intermittent unidirectional rotation of each of the rollers. Each of the rollers is provided with a braking member, which includes a circumferentially extending brake plate that presses against an outer periphery of the corresponding roller.

Abstract: A cover-tape feeding apparatus for feeding a peeled portion of a cover tape of a carrier tape which includes an accommodating tape having, at a predetermined pocket pitch, pockets accommodating electric components, respectively, and the cover tape attached to the accommodating tape to close the pockets, and which is fed in a lengthwise direction thereof at a carrier-tape-feed pitch equal to a quotient obtained by dividing the pocket pitch by an integral number, the apparatus including a conveying belt which is endlessly wound on at least two pulleys and at least a portion of which supports the peeled portion of the cover tape; a reciprocative member which is reciprocated forward and backward in opposite directions substantially parallel to the portion of the conveying belt; and a pinching device including a pair of pinching members at least one of which is provided on the reciprocative member, the one pinching member cooperating, when the reciprocative member is moved forward, with the other pinching member t

Abstract: The present invention relates to a hog ring clamping device such as a C ring clamping device. In the hog ring clamping device of the invention, a knock pin is mounted to a movable member of a jaw driving unit, a pivotable member is mounted to a hog ring clamping device body, the pivotable member is pushed against the knock pin by means of spring, a feed member is mounted to the pivotable member so that it can come into contact with hog rings engaged with a magazine, and a presser wheel is mounted to the hog ring clamping device body through a unidirectional rotating unit so as to be in contact with the hog rings engaged with the magazine.

Abstract: A rotary die cutter system minimizes the amount of scrap between successive blanks cut from web material by holding the web against backward movement at a position spaced upstream from the nip defined by the die and anvil cylinders, retracting the cut leading end of the web through a predetermined distance by means of a fluid pressure cylinder in response to release of the web by the cut-off knife at the trailing edge of the die on the die cylinder such that on the next cycle, the leading edge of the die will engage the web at a position spaced so close to the retracted leading end of the web that contiguous portions of a single blank can be cut from the web during successive revolutions of the die cylinder.

Abstract: A brake device which is used to prevent reverse movement of a belt run and which includes a wedge member which is pivotally supported above the belt run. Upon reverse movement of the belt run, the wedge member is drawn into pinching contact with the belt.

Abstract: A strip feeder particularly for punch dies comprises drive and idler rollers engageable with opposite faces of the strip being fed, a spring-loaded member displaceable in a first direction during the foward stroke upon receiving an impact and returned by the spring during the return stroke, a first one-way clutch effective to decouple the drive roller from the displaceable member during the forward stroke and to couple same during the return stroke, and a second one-way clutch effective to couple the idler roller to the fixed frame during the forward stroke and to decouple same during the return stroke. The described one-way clutch comprises a first member having an external annular surface and a second member including an internal bore for rotably receiving the latter.

Abstract: The apparatus and method of this invention pertains to a web film advance in which a film advancing roll is carried on a frame moved by a reciprocating pitman arm. This arm is adjustable as to its stroke or travel so that a corresponding travel of the frame is also selectively adjustable. The film advancing roll is carried by a shaft mounted in bearings and is prevented from turning in one direction by a one-way clutch apparatus. This clutch allows the roll to be rotated only when the frame and roll are moved rearwardly. During this film feeding advance by the roller a rotation of the roller is achieved by a roller chain and a sprocket or a timing belt and toothed pulley. This chain or belt may be moved a small amount in response to an electrical signal to bring the web of film or paper into registration in accordance with mark indicia. Bags or simply formed, filled and sealed packages may be made by and on this simplified yet highly reliable film advancing apparatus.

Abstract: Apparatus of the type wherein a desired length of adhesive strip is fixed to an edge of a stack of sheets with heat and pressure includes automatic means for reliably providing the desired length of strip from a roll of adhesive strip. The automatic means include a pair of rollers which engage and feed strip, one of the rollers being mounted for free rotation and the other of the rollers being coupled to a shaft by a one-way clutch. Means rotate the shaft from a start-of-feed position a selectable amount in one direction, with said other roller and clutch engaged, to feed the desired length of strip and, thereafter, a spring counter rotates the shaft to the start-of-feed position, said position being determined by an abutment which limits rotation of a gear coupled to the shaft. A flywheel frictionally coupled to the shaft prevents bounce when the abutment limits rotation of the gear, thereby preventing rotation of the shaft in said one direction and, consequently, unmetered feeding of adhesive strip.
