| 20090092474 | Tray stacking apparatus - System and apparatus for automatically stacking trays involve receiving trays on a receiving platform, detecting the arrival of the tray on the platform, and synchronously displacing the tray to a moveable tray cart located in a tray stacking area of a stacking tower. An automated tray sliding mechanism displaces the tray to the stacking area upon detection of the tray at the receiving platform. Trays displaced in the stacking area of a lower section of a stacking tower form a tray stack. A stack elevator of the tower engages and elevates the tray stack providing a space beneath the stack allowing the next incoming tray to be displaced into the stacking area and assume the provided space beneath the tray stack, the incoming tray thereby assuming the lowermost position in the tray stack. Trays are added to the lowermost position in the stack until the stack height reaches a predetermined height and is removed from the stacking area. | 04-09-2009 |
| 20090185891 | TRAY HANDLER AND METHOD - The present invention is directed to a tray handler for stacking and de-stacking ophthalmic prescription trays. The tray handler includes a plurality of spaced clamp assemblies defining a stack area along a conveyor, a lift plate, and first and second actuators. The lift plate is operably disposed within the stack area. The first actuator is operably associated with the clamp assemblies, which are inwardly and outwardly moveable relative the lift plate upon actuation of the first actuator. The second actuator is operably associated with the lift plate, which is vertically moveable within the stack area upon actuation of the second actuator. A controller is in communication with the first and second actuators and controls actuation thereof. A method of handling ophthalmic prescription trays is also disclosed. | 07-23-2009 |
| 20110052361 | SHEET STACK LOADER AND SHEET LOADING METHOD - A sheet stack loader includes a loading table to support a first folded sheet bundle, an elevator to lift the first folded sheet bundle from the loading table, and a conveyer to convey a second folded sheet bundle into a space between the loading table and the first folded sheet bundle, wherein the space is created by the elevator. | 03-03-2011 |
| 20140308107 | Last-in, first-out bottom-loading, bottom-deloading vertical storage and retrieval system and method of manufacture - A last-in, first-out bottom-loading, bottom-deloading vertical storage and retrieval system comprising a raising and lowering means such as a jack or a leveraged arm, a frame with a pawl or pawls for supporting a tray, a plurality of trays, and a deloading means for disengaging the pawl or pawls that support a tray in the frame. A method of manufacture of the same. | 10-16-2014 |
| 414795000 | Includes rotary deliverer | 1 |
| 414795100 | Coacting screws | 1 |
| 20220135350 | STACKING SYSTEM AND METHOD - A system for forming horizontally stacked groups of containers includes an infeed screw set, an orienting screw set, and a grouping mechanism. Containers are presented to the infeed screw in a vertical orientation, and are progressed from the infeed screw set to the orienting screw set via a transitioning pocket defined by overlapping pockets of the infeed and orienting screw sets. As containers are progressed through the orienting screw the containers are rotated via a series of orienting pockets to a horizontal orientation and progressed via a series of nesting pockets to form a series of horizontally nested containers. The series is discharged to a grouping mechanism which separates a predefined number of containers from the series to form a horizontally stacked group, which is outfed from the stacking system. | 05-05-2022 |
| 414795200 | Includes means for raising highest article and lowering it upon newly delivered article | 2 |
| 20100104412 | SYSTEM FOR STACKING AND UNSTACKING MOLD UNITS - A system for stacking and/or unstacking stackable units in a units-handling installation, wherein the system comprises a frame carrying holding means for taking a stackable unit at a time from a stack of units and remove the units, one at a time, from the stack, and for taking units provided at the system to stack them into a stack of units, and conveyor means for receiving units to be stacked and delivering unstacked units out of the system. | 04-29-2010 |
| 20110038702 | CONTAINER FILLING PLANT HAVING A DEVICE FOR STACKING PRODUCT GROUPS OR SETS, AND A DEVICE FOR STACKING PRODUCT GROUPS OR SETS IN A CONTAINER FILLING PLANT, AND A DEVICE FOR STACKING PRODUCT GROUPS OR SETS - A container filling plant having a device for stacking product groups or sets, and a device for stacking product groups or sets in a container filling plant, and a device for stacking product groups or sets. The abstract of the disclosure is submitted herewith as required by 37 C.F.R. §1.72(b). As stated in 37 C.F.R. §1.72(b): A brief abstract of the technical disclosure in the specification must commence on a separate sheet, preferably following the claims, under the heading “Abstract of the Disclosure.” The purpose of the abstract is to enable the Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract shall not be used for interpreting the scope of the claims. Therefore, any statements made relating to the abstract are not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner. | 02-17-2011 |
