摘要:
A self-contained no-feed-roll computer controlled corrugated board or paperboard sheet feeder apparatus 200 is configured to upgrade an installed corrugated board processing machine (e.g., 10) and includes a feed table surface 210 for boards (e.g., 2) having drive wheels (222W, 224W, 226W) in an initial variable velocity zone 220 which drives the board in a first motion profile through a first vacuum zone, and a second velocity zone 230 which then drives the board in a second motion profile through a second vacuum zone Retrofittable sheet feeder 200 also includes a controller 300 configured to receive predetermined velocity signals from the host machine 10 and generate (i) a first initial variable velocity control signal for initial variable velocity zone 220 and (ii) a second velocity control signal for second velocity zone 230 in response.

A corrugated paperboard sheet feeding apparatus comprises: a plurality of sheet feeding rollers; a grate formed with a plurality of opening portions for receiving the sheet feeding rollers and configured to switch between contact and non-contact states of the corrugated paperboard sheet with respect to the sheet feeding rollers; and a suction box configured to suck the corrugated paperboard sheet downwardly by gaps between the sheet feeding rollers and the opening portions, wherein each of the gaps is formed to be 10 mm or less, and wherein the apparatus further comprises a mat switch for detecting an entry of a person into an area in a sheet feeding section, and a control device for stopping movement of the sheet feeding rollers and/or the grate when the mat switch is turned on.

A sheet-like object transporting device disclosed herein includes a transport plate having suction holes made penetrating therethrough, a fan that sucks in air through the suction holes, a belt that moves along an upper surface of the transport plate, and a controller. Width of the belt corresponds to width of the transport plate. The belt has an open zone whose form corresponds to a sheet-like object. A sheet-like object is loaded on the transport belt so as to close up the open zone. The belt is moved with the sheet-like object attracted onto it by suction. The sheet-like object is stably held onto the transport belt, contacting the peripheries of the open zone without misalignment, and is stably transported without moving out of position or upward. It is possible to transport a sheet-like object attracted onto the belt, while suppressing suction force wasting.

A medium supply device includes a feeding unit that feeds a medium among one or more media placed on a placing table, a separating unit that is arranged to come into pressure-contact with the feeding unit, and a blocking portion that is movable and blocks a space formed between the feeding unit and the separating unit in an upstream side of a nip region in a conveying direction of the medium. When one of the media placed on the placing table is fed by the feeding unit and the one or more media are placed on the placing table, the space is formed by the medium fed by the feeding unit, the separating unit, and the one or more media placed on the placing table.

A station for loading plate elements (1, 1a), from an initial pile of the elements in a storage device (4) to an infeed station for a machine for processing the elements. An unloading device (7) unloads the elements (1a) from the initial pile (3). An intermediate storage device (16), stores the unloaded elements (1) in the form of an intermediate batch (19) and is positioned downstream of the unloading device (7), a conveyor device (18) for conveying the elements (1) from the storage device (16) to the infeed station, and a shingling device (21) for shingling the elements (1) and being positioned downstream of the storage device (16).

摘要:
A timed feeder for feeding corrugated boards to nip rolls of a box finishing machine. A feed member is raised to the feed path to engage and drive a board to the nip rolls and then lowered away from the feed path until the next cycle. An indexing drive mechanism, driven by a computer-controlled servo motor, activates the feed member and has a feed phase when it drives the board to the nip rolls, and a dwell phase when the feed member is away from the feed path and the output shaft of the indexing mechanism is at zero velocity. During the feed phase, the output shaft of the indexing mechanism accelerates the feed member and the board beyond the nip roll velocity and then decelerates them to the nip roll velocity at the point where the board enters the nip rolls. During the dwell phase the input shaft which was at constant velocity during the feed phase, is either accelerated and then decelerated or decelerated and then accelerated to shorten or increase the duration of the cycle allowing different size articles to be fed with minimum or zero spacing downstream of the nip rolls.
摘要:
The present invention relates to a simplified mechanism for feeding and advancing popcorn bags or other receptacles for use in food or consumable filling applications, such as microwave popcorn to downstream processing stations. More specifically, the present invention includes the provision of a vacuum to draw a bag into operative association with a moving belt in order to advance the bags from a stack or supply.
