  • Patent number: 9371207
    Abstract: In an image forming apparatus, a discharge roller discharges a sheet conveyed by a first conveying path. The discharge roller switches between: a mode of conveying a sheet in a sheet discharging direction to discharge a sheet; and a mode of reversing a direction of conveying a sheet from the sheet discharging direction and feeding a sheet to a re-conveying path. A pivot plate at an open position constitutes a second conveying path. The pivot plate at a closed position closes the second conveying path. The pivot plate is provided with a penetrating portion penetrating the pivot plate over an entire thickness of the pivot plate. The penetrating portion constitutes part of the re-conveying path when the pivot plate is disposed at the closed position. Part of the pivot plate is exposed outside the housing.

  • Patent number: 7828281
    Abstract: When a sheet is conveyed from a processing tray to a stacking tray, a bar-like pushing member is moved in a direction of the stacking tray in synchronization with an ejector. Consequently, simultaneously with the movement of the sheet by the ejector, a lower surface of a leading end of the sheet is pushed to relax and reduce a contact force between the lower surface of the leading end of the sheet and the stacking tray (or an upper surface of a sheet already stacked on the stacking tray). As a result, static friction at the leading end of the sheet is changed to dynamic friction and the entire sheet is conveyed to the stacking tray without bending.

  • Patent number: 5722651
    Abstract: A system for separating alternately stacked first and second sheets (5,6) such as film plates and paper. The system comprises a first sheet holding device (8,9) for holding a first sheet (5) of the stack; an eccentric (2) for causing relative separation movement between a sheet held by the first sheet holding device and the remainder of the stack so that the held sheet is positioned spaced above the remainder of the stack, the first sheet holding device being laterally moveable to feed the separated first sheet to an exit (12). A second sheet removal device (14) is provided for laterally feeding a second sheet (6) from the stack to an exit in generally the same lateral direction as the first sheet.

  • Patent number: 5713718
    Abstract: An object discharge mechanism of an object picking device for discharging a bottommost object from a stack of objects includes a bottom platform on which the bottommost object of the stack of objects rests. The platform has a longitudinal slot running along an object discharge direction. The upper portion of a belt, stretched between two vertically mounted pulleys, runs through the longitudinal slot parallel to the upper surface of the bottom platform. Discharge projections are mounted periodically on an outer surface of the belt. The discharge projections push objects across the bottom platform in the object discharge direction when the belt is rotated. The object discharge mechanism also includes a lifting member for lifting all objects above the bottommost object in the stack of objects. The lifting member reduces the frictional force created by the weight of the stack of objects on the bottommost object during discharge of the bottommost object.

  • Patent number: 5645679
    Abstract: The conveying device exhibits a plurality of clamps which are each articulated, via a carrying arm and a linking member, on rotational elements. The pivot position of the carrying arm is controlled by a first slotted-guide path and, separately from this, the position of the linking member is controlled by a second slotted-guide path. This permits pivoting of the clamps even independently of the movement of the carrying arms. The clamps can thus be controlled in an optimum manner for the respective purpose. In particular, it is possible, with constant speed of the rotational elements, to change the speed of the clamps and, at the same time, to control the direction of the clamps independently.

  • Patent number: 5402221
    Abstract: An imaging apparatus having a drive roller in an imaging zone includes a guideplate assembly for controlling the velocity of a substrate. The assembly has a guideplate with the inlet end disposed adjacent to a dispensing magazine and the outlet end disposed adjacent to the imaging zone. The guideplate assembly has a pushing finger movable therealong, a velocity-controlling sidewall and a spring-loaded biasing member disposed along opposed edges of the guideplate. The biasing member urges an edge of the substrate into frictional contact against a portion of the sidewall directly opposite the member while the pushing finger simultaneously engages the substrate to propel the substrate at a predetermined controlled velocity toward the outlet end of the guideplate against the frictional force imposed on the substrate by the sidewall. The predetermined controlled velocity is at least ninety percent of the rotational speed of the drive roller.

The label feeder comprises an open frame with a substantially horizontally extending supporting arm extending therefrom and a motor mounted thereon. The supporting arm has at least one label hold bin for holding the labels mounted on it as well as an endless conveyor for moving the label from the label hold bin to a position directly over the open-top container. A loading ram system and an unloading ram system, each with vacuum means, are mounted on the supporting arm to pick a label from the hold bin and deposit a label into the containers, respectively. The label feeder is portable and is used as needed in association with the packaging machine to place the individual label into the open-top container either before or after the articles have been added and before the container is sealed close.

  • Patent number: 5350167
    Abstract: An apparatus for transporting sheet-like products includes a belt conveyor with a flexible conveyor belt. The conveyor belt is driven in a conveying direction at a conveying speed. A takeover conveyor has individually controllable clamps which are arranged one behind the other on a carrying member. The clamps are driven in a rotating direction, and the clamp mouths are directed in the takeover region forward in rotating direction. The products fed to the takeover region are in each case pressed against the conveyor belt by a pressing roller at the free end of the first clamping jaw of the clamp. Since the clamp speed of the clamps is greater than the conveying speed, the following clamp thus catches up with the held product and seizes it at the trailing edge.

  • Patent number: 5301937
    Abstract: A method and apparatus is provided for processing printed products such as newspapers, magazines or parts thereof in which the printed products are transported by controllable grippers of a conveying device wherein the printed product is held at a first edge which runs transversely to the conveying direction. The printed products are conveyed at a set conveying speed. The grippers are at least partially opened to displace the printed products in the mouth of the grippers. The printed products are then displaced in the mouth of the grippers until the second edge (which is opposite the first edge) is brought to rest on a straightening mechanism. The straightening mechanism is driven substantially in the conveying direction. The grippers are then closed to continue transporting the printed products. If the second edge of the printed products leads relative to the first edge, the straightening mechanism is driven at a lower speed than the conveying speed.

  • Patent number: 5297790
    Abstract: The driver (12) comprises a carrier (14) for attachment to a conveyor, for example an endless chain. A pusher (16) made of hard-wearing material is attached to the carrier (14) in such a way that when the support moves forwards the pusher engages a rear edge of a sheet (10) to be fed. The pusher (16) is supported through at least one elastic spacer (18) on the carrier (14), in a rearwardly resilient manner. In a preferred embodiment of the driver (12), the pusher (16) comprises a flexible metal sleeve (30) which near each of its two ends rests, by way of a respective spacer (18) in the form of an electrically insulating washer, on a shaft (20) attached to the carrier (16). This makes high rates of acceleration possible when feeding thin metal sheets on a can welding machine, without the sheets being damaged by the driver (12).
