In a system for transferring groups of containers from one location to another, a loading station including a transfer mechanism for continuously delivering rows of containers from the transfer station to a tray loading station. A device at the tray loading station is included for cycling the tray in a predetermined controlled sequence to receive rows of containers delivered by the transfer mechanism and to position them in a compact array in the tray.

A system for automatically loading and unloading bottles, vials, or other containers into and out of a freeze dryer or other material treating apparatus includes a loading station and a conveyer for bringing bottles to the loading station. A transfer vehicle movable between the loading station and one or more freeze dryers includes a horizontally arranged platen for supporting an entire dryer shelf of bottles. When the vehicle is aligned with the loading station, a pusher bar slides bottles from the loading station onto the vehicle platen. The vehicle then moves to a dryer where the platen aligns itself with one of the dryer shelves. A guide bar at the rear end of a rectangularly shaped lasso or transfer cage moves forwardly pushing the bottles onto the shelf. The forward end of the cage is then raised above the height of the bottles and removed from the dryer. To unload a dryer shelf, the cage enters the dryer above the bottles and the forward end drops down behind them. The bottles are then drawn out from the shelf onto the vehicle platen by the cage. Thereafter, the vehicle is moved to an unloading station where an unloading transfer guide at the forward end of the vehicle moves rearwardly to push the bottles from the platen onto an unloading conveyer.

An article transfer device for transferring articles from a first position to a second position including a transfer screw, a conveying system, a stationary dead plate and a pressure adjustment wall. The screw is constructed from a flexible material and is essentially a continuous helical spiral having its ends connected to a support structure. Because of the flexible nature of the screw, different size articles can be transferred across the dead plate without having to change the screw. The article transfer device is useful in a clean room and less clean room application where articles need to be transferred between the rooms without returning any contaminants to the clean room. No individual part of the transfer device moves from the clean room to the less clean room and back again, thereby maintaining the sterile environment in the clean room. When it is desired that a different size article be transferred between the rooms, the pressure wall is adjusted so that the screw conforms to the different size articles and transfers the same. Lost production time and additional labor are eliminated as a result of the conforming nature of the article transfer device.

An article accumulator utilized between a product infeed line and a discharge conveyer feeds articles from the infeed to the discharge conveyer in a single, continuous line. The accumulator includes a wide horizontal moving conveyer belt that accumulates articles in the event of a backup at the discharge end. A slow moving flexible guide belt located just above the conveyer belt and angled toward the discharge conveyer engages the sides of the articles and helps to move them toward the discharge conveyer. In the event that a substantial number of articles accumulate on the accumulator conveyer belt, these articles push sideways on the guide belt forcing it rearwardly behind a guide rail that runs along the length of the guide belt. The articles then engage the guide rail and are less influenced by the movement of the guide belt. This arrangement helps to ensure that the articles that are first placed on the conveyer belt tend to be the first articles to be discharged.

A continuous passive motion (CPM) device includes a foot support plate and a toe plate. The foot support plate pivots back and forth, driven by a rod connected to a motor. A toe plate pivots separately from the foot support plate, and receives its motive power solely from the foot support plate. The engagement of a pair of pins, one pin connected to the foot support plate and the other pin connected to the toe plate, causes the toe plate to pivot at the desired moment. The toe plate pivots in the opposite direction from that of the foot support plate, and pivots only when the foot support plate reaches a predetermined angle. At other times, the toe plate does not move. The latter arrangement enhances the level of comfort felt by the patient, by increasing the effective angle of flexing of the foot, while limiting the amount of flexing of the heel to a comfortable level. The positioning of the pins determines through how many degrees the toe plate pivots for each degree of rotation of the foot support plate.

Apparatus and method for imparting continuous passive motion to the foot

A stack of baskets carrying frozen chickens or the like are mounted on a dolly which is wheeled into a denester having spaced apart vertical side walls. Each of the side walls carries a vertically moving conveyor having spaced hooks adapted to be moved inwardly to engage the baskets. As the conveyors move upwardly, the top basket is lifted from the top of the stack. As the conveyors continue to move, the next basket is lifted and this continues until all of the baskets are lifted off of the dolly and are spaced apart from each other. A horizontal conveyor is then interposed beneath the lowermost basket. The vertical conveyors are moved downwardly until the lowermost basket rests on the horizontal conveyor and the conveyor hooks are removed therefrom. This basket is then conveyed horizontally to make room for the next lowermost basket and the process continues until all of the baskets have been denested.

Basket denester

A device for accumulating objects carried between an up stream location and a down stream location, including a frame mounting a conveyor to define a path through the device from an entrance to an exit. The device includes a magazine on the frame and contains a plurality of chambers, the chambers being movable to position each chamber in operable relationship with the path. The chambers each include a plurality of object nests individually sized to each carry an object into or out of the path when the chamber is moved. Also provided are stop operable to regulate the flow of objects along the path to selectively position objects for accumulation by the magazine.

Carton accumulator

In an article elevating apparatus, articles such as cigarette cartons, are picked up at a loading station by inclined roller carriers moving in an upward vertical direction. During upward movement the articles are held on the roller carriers by sliding engagement of the downward end of the articles against a vertical rail. The articles roll off of the carriers at a discharge station defined by the upper end of the rail.

A carton inspecting and conveying apparatus is disclosed as including a lower horizontal conveyor formed by two parallel spaced plastic chain loops with retractable pawls therebetween for stopping cartons at stations along the conveyor. At one such station, jets of air are directed at each carton to open any improperly sealed flaps, open flaps being photoelectrically detected. A pneumatic ejector at a subsequent station is selectively actuated by an electronic control unit responsive to the photodetector to remove unsealed cartons from the conveyor. A pneumatic lifting head is provided to transfer cartons from the conveyor to an accumulator column in the event of a carton backup. An elevator having platforms passing between the plastic chains lifts cartons from the lower conveyor, and a rotary transfer device places them on an upper outfeed conveyor belt.

Carton inspecting and conveying apparatus

A skateboard includes conventional carriages and axles supported on the underside thereof. Each axle has a truck pivotally supported on either end and each truck includes front and rear wheels. Each of the four trucks is pivotal independently of each of the others and is spring biased in an intermediate position. An endless belt passes around and is supported by the wheels on each of the four trucks.
