专利汇可以提供Accumulator for cartoning machine专利检索,专利查询,专利分析的服务。并且Automatic cartoning machine including twin cartoning units mounted in a common framework having a conveyor for conveying a stack of paper cups or other article for each unit. The units are similar having their loading stations adjacent each other to receive the articles. Each unit has a plurality of cams making one complete revolution for one cycle of operation. Each cycle includes removing a collapsed glue end carton from the bottom of a magazine, transferring it to a combined loading and squaring-up station where the carton is squared up and the article is loaded into the carton. The cycle is started by arrival of the article at a station and is terminated by one complete revolution of the cams. The minor flaps pass through a glue applicator on the way to the station. After the flaps are partially sealed, the carton is elevated through a compression chute and the filled and sealed carton is then ejected horizontally and guided to fall in upright position in front of an accumulator which operates in timed relation with the supply of filled and sealed cartons and with the transfer of the article from the conveyor to a loading tray. Cam means controls supply of the upright cartons to a row former, a given carton pushing on the cartons ahead of it until the row is filled, the leading carton controlling a trigger to complete a power drive to eject the row as a unit, the individual cartons and the rows leaning downhill to form a compact group of rows of upright elongated cartons.,下面是Accumulator for cartoning machine专利的具体信息内容。

1. An accumulator comprising a row former for upright filled and sealed cartons, an oscillating transfer device for supplying the cartons in upright position to said row former, a rotary cam operated means for oscillating said transfer device, a row pusher for ejecting a row of cartons from said row former, a pivot supporting said row pusher for movement to idle or active position, a rotary cam operated drive, a pawl on said row pusher, means supporting said pawl for movement to idle position or to active position in the path of said drive, and a trigger device in the path of the foremost carton of a row of cartons for operating said pawl to active position when the row is full to connect said drive to said pawl to operate said row pusher to eject the row of cartons from said row former, said row pusher and pawl returning to idle position after said row is ejected to disconnect said drive from said pawl to prepare said row former for receiving the next row.
2. An accumulator comprising a row former having an inverted U channel for guiding and restraining the tops and sides of an upright longitudinal, horizontal row of elongated filled and sealed cartons and a base for supporting the bottoms of said cartons, means for supplying said elongated upright cartons one at a time to said U-channel to form a row thereunder, and means acting when the row is full to transversely eject the row as a unit from said row former to prepare said row former for formation of the next row.
3. An accumulator comprising a row former having means for supporting an upright longitudinal row of filled and sealed cartons, means for supplying upright cartons one at a time to said supporTing means, means acting when the row is full to transversely eject the row as a unit from said row former to prepare said former for formation of the next row, said row former comprising an inverted U-channel guiding and supporting the tops of a row of said upright cartons, and an inclined base supporting the bottoms of said cartons to cause the cartons to move uphill longitudinally to form a row and also uphill transversely to form successive rows constituting a compact group of rows of upright cartons.
4. An accumulator comprising a row former having means for supporting an upright longitudinal row of filled and sealed cartons, means for supplying upright cartons one at a time to said supporting means, means acting when the row is full to transversely eject the row as a unit from said row former to prepare said former for formation of the next row, said row former guiding and supporting the row of said upright cartons, said row former having an inlet for the individual cartons and a lateral outlet for the row of cartons as a unit, as inclined base supporting the bottoms of said cartons to cause the cartons to move uphill longitudinally to form a row and also uphill transversely to form successive rows constituting a compact group of rows of upright cartons, said inlet having a catch preventing the cartons from emerging from said inlet, and said outlet having a catch preventing a row of the cartons from reentering said row former.
5. Accumulator according to claim 4, said row former being in the form of an inverted U-channel supporting the tops of a row of cartons, said U-channel having said inlet at one end thereof and said outlet at the side thereof, said inlet catch being in the form of a pivoted member in the path of the cartons, said outlet catch forming a pivoted side of said U-channel.
6. An accumulator according to claim 4 further including a chute, means for supplying elongated filled cartons in horizontal position longitudinally, one at a time to the top of said chute, the leading end of each horizontal carton thus supplied extending unsupported whereby the leading end of the carton drops to fall by gravity, said chute including means guiding the falling carton to assume an upright position as it drops to rest on said base.
