    Abstract: A printing plate sucker capable of stably suction-adhering and sheet-feeding both a printing plate and a protective sheet simultaneously without causing wrinkling at the protective sheet during the suction-adherence and sheet-feeding. The sucker is structured by a main body portion formed of a stiff body, a skirt portion formed of a resilient body, and a spring. When a moment from a printing plate acts on the sucker during sheet-feeding, the spring resiliently deforms. Thus, the main body portion is displaced (inclined) in the moment application direction, effective weight on the sucker is reduced, and a state in which a reduced moment acts on the sucker is achieved (the moment is substantially absorbed). Furthermore, the spring which redirects the moment is structured separately from the main body portion and skirt portion. Therefore, the sucker will not be deformed, an interleaf sheet will not be hoistingly deformed, and wrinkling will not occur.

  • Patent number: 6039530
    Abstract: A vacuum manipulation device with a lifter hose, which can be connected to a vacuum-generating device, and with a suction gripper device, which can be placed on an object to be manipulated, by means of which the object can be drawn-up and, by contracting the lifter hose, can be lifted. In order to prevent the suction gripper device from snapping upward in case of an unintentional release of a drawn-up object, the manipulation device features a weight-actuable regulating element which, under the effect of the weight of an object drawn by suction against the suction side of the suction gripper device, blocks a flow cross section into the interior of the lifter hose, and unblocks it in the unoccupied state of the suction gripper device.

  • Patent number: 5816156
    Abstract: A hollow cylinder is fitted with a piston, whose hollow rod or shank protrudes downward from the cylinder to apply lifting suction to print media. The upper end of the cylinder communicates with a suction system. In the cylinder side walls, main passageways and reapportioning passageways apply suction to the underside of the piston when the piston is less than fully extended, drawing the piston down to extend the shank. When the shank is fully extended the piston blocks the reapportioning passageways--reallocating more of the available suction to other feet, in the same system, that remain unextended.

  • Patent number: 5688008
    Abstract: A suction device for gripping an article has a sucker (1) with a suction lip (12). The sucker is movable between inner and outer positions in the inlet end (2) of a suction line and can be moved angularly. A reset element (3) moves the sucker to its outer position. In the inner position, the sucker forms a sealing connection with the inlet end. In its outer position, leakage air flow can pass around the outside of the sucker and into the suction line. When the sucker is in its outer position and the suction lip is closed by an article to be gripped, a pre-depression of pressure less than the maximum suction is caused because of the leakage flow. As the result of that pre-depression, the sucker is moved to its inner position, causing a sealing connection between the sucker and the inlet end of the suction line. The depression is then increased, increasing the suction grip on the article.

  • Patent number: 5377968
    Abstract: A feeder in a paper sheet processing machine has a plurality of lifting suckers for lifting a paper sheet from a stack of paper sheets. After the sheet is lifted into a raised position it is entrained by a transport device and transported to a paper sheet processing unit. A force potential acts permanently on the lifting sucker downwardly in a direction towards the stack. The lifting sucker is lifted against the force potential in a cyclically controlled manner in a lifting and lowering stroke. A retaining collar is formed on the lifting sucker beneath which a retaining support engages so as to delay a return of the lifting sucker to its lower position and to stop the sucker in the lower position. The retaining support is mounted shiftably parallel to the stroke direction of the lifting sucker. Controlled pneumatics communicate with the retaining structure, so as to shift the same as a function of the stroke position of the lifting sucker.

  • Patent number: 5219432
    Abstract: A device for unstacking flat objects comprises an unstacking head (2) provided with a suction cup (88) for grasping the first flat object in a stack of such objects presented thereto and for moving a grasped flat object towards an exit position (40) in which the object is released. The suction cup (88) is a bellows suction cup made of a flexible material such that when it grasps the first flat object in the stack, it retracts under the effect of the suction and entrains at least the surface of the grasped object therewith as it retracts. A shoe (90) having a surface close to the grasping plane of the suction cup is disposed adjacent to the suction cup in fixed relationship relative to the mount (50) carrying the suction cup. The shoe thus constitutes an obstacle to the surface of a grasped flat object, thereby warping said surface as the suction cup retracts.

  • Patent number: 5180156
    Abstract: Disclosed herein is a method of feeding sheets. The sheets such as photographic photosensitive films are fed one by one by a suction pad in an image recording apparatus. The suction pad is displaced at a higher speed toward a stack of sheets, and then the speed of the suction pad is reduced to cause the suction pad to approach the stacked sheets ata lower speed. It is thereafter detected whether or not an uppermost one of the stacked sheets is attracted by the suction pad. Further, the suction pad is stopped from being moved toward the stacked sheets immediately upon detecting that the suction pad has attracted the uppermost sheet, and is also displaced away from the stacked sheets until the suction pad reaches a desired position.
