Abstract: Disclosed herein is a film fitting head which holds a tubular film fitted on a mandrel in a stable position and can prevent the film from rotating and being displaced in a peripheral direction. The film fitting head (40) includes a mandrel (M) for receiving a tubular film (L) in a fitted state in a film supply position, feeding the tubular film in a film fitting position, and fitting the tubular film onto a body portion of a container. The mandrel (M) includes a film holding portion (85) provided above a lifting member (88) located in a standby position. An outer peripheral surface of the film holding portion (85) has a tapered surface that is tapered down toward a top, and an outer peripheral length of a lower end (85a) of the film holding portion (85) is set to be approximately equal to a peripheral length of the tubular film (L) in an open state.

Abstract: Provided is a film fitting system in which the formation and supply of a tubular film are not disrupted even if contents have spilled out from a container at a tubular film fitting position. A film fitting system 10 has a third container conveying device 16 and a film fitting unit 20. The film fitting unit 20 includes a tubular film forming unit 50 that cuts a long tubular film base material to a predetermined length to form a tubular film, and mandrel heads 40 that receive the tubular film formed by the tubular film forming unit 50 at a film supply position ? and push up the tubular film in an opened state at a film fitting position ? so as to fit the film on a container. The tubular film forming unit 50 is configured to form the tubular film and deliver the tubular film to the mandrel heads 40 at a position separated from a container conveying path of the third container conveying device 16 when viewing the system from above.

Abstract: An opener mechanism in which a label folded in a sheet shape is opened and fitted to a target body is provided with first suction rods which suck one side of a label, second suction rods which are arranged to oppose the first suction rods and suck the other side of the label, and a drive mechanism which induces movement of the first and second suction rods toward or away from each other. Suction hole arrays in which a plurality of suction holes which suck the label are aligned in a line are formed on the surfaces facing one another of the first suction rods and the second suction rods. The suction holes are arranged in such a manner that the suction hole arrays of the first suction rods and the suction hole arrays formed in the second suction rods opposing the first suction rods are at least partially nonparallel.

Abstract: A film fitting system which fits a tubular film on a fitting target including a fitting device which fits, at a predefined fitting position, the tubular film on the fitting target which is transported; and a transporting device which receives the fitting target at a predefined supplying position, wherein the transporting device includes a mount which is moved in a state where the fitting target is placed thereon; a positioning member which is moved in a linked manner with the mount and which positions the fitting target with respect to the mount by contacting a part of the fitting target; and a moving device which moves the positioning member to a reference position, and a retracted position where the positioning member is separated from the fitting target at least at the fitting position.

Abstract: Provided is a film opener and a film placement system capable of smoothly and securely placing even a thin tubular film around a placement target. The film opener is mounted to a film placement apparatus for opening a tubular film supplied so as to be sheet-like folded and placing the tubular film around a bottle, and includes first and second suction rods and third and fourth suction rods that grip a sheet-like folded label by suction, and the first and second suction rods, and the third and fourth suction rods, separate from each other, and thereby the label is opened, and in a state where the label is open, suction holes of the first suction rod and suction holes of the fourth suction rod oppose each other, and suction holes of the second suction rods and suction holes of the third suction rod oppose each other.

Abstract: A label supplying device is provided, whereby false bonding at a cylindrical label's end is reliably released, and ill-timed supplying of the label to the label supply position hardly occurs. The supplying device includes: a material delivery unit (10) for continuously delivering an elongated label base material (M) paid out from a material roll by a pay-out unit; a cutting unit (20) for cutting, at a predetermined pitch, the base material (M) delivered by the delivery unit (10); an upstream and a downstream belt transfer units (30, 40) for transferring labels (L), formed by the cutting of the cutting unit (20), to a label supply position (?); and a separation unit (50) for separating overlapping edges of the upper end of the label (L) (upstream end in the transfer direction of the label (L)) during the transferring of the label (L) by the upstream transfer unit (30).

Abstract: A label fitting device provided with a plurality of mounting bases which move along a transport path while target bodies for fitting are respectively mounted on the bases; a fitting head which is provided directly above each mounting base and moves together with the mounting base; and a label supply mechanism provided directly above the transport path to supply labels. Each fitting head includes a take-up member which receives a label held by a label supply unit when the head passes a supply position, and an opener mechanism which receives the label from the take-up member, and thereafter opens the label and fits the label on the target body mounted on the mounting base.

Abstract: A film supplying apparatus includes: an upstream belt conveying unit and a downstream belt conveying unit that sequentially convey a label formed by cutting a label-forming base material, to a label delivery position; a label detection sensor that detects the label at an upper position of the downstream belt conveying unit; an encoder attached to a take-up spindle of a label delivery apparatus; and a control unit that calculates the amount of shift in the label on the basis of a label detection signal from the label detection sensor and a pulse signal from the encoder, and controls the operation of the downstream belt conveying unit conveying the label, so as to convey the label and stop the label at the label delivery position, while modifying the amount of shift.
