A method and apparatus for stacking products such as trays are disclosed utilizing a rotary ferris wheel device which raises product off a conveyor and places it on a platform where it is pushed off unto additional product being conveyed on the conveyor. Specifically, an arm is rotated from a noninterfering position below the conveyor until a pivotally mounted shoe on the free end of the arm abuts the product without gripping or attachment thereto, raises the product off the conveyor, and places the product on a platform. The next product on the conveyor is allowed to be conveyed on the conveyor without interference. After the arm is rotated from under the platform into a noninterfering position below the conveyor, the product is pushed off the platform unto the product which remained on the conveyor. Thereafter, the stacked products continue to be conveyed on the conveyor. In the preferred form, the shoes of the arm are maintained in a parallel relation to the conveyor by sprockets rotatably fixed to the shoes and to the shaft forming the pivot axis for the arm, with the sprockets being in driving relation to each other by a chain extending therebetween.

Method and apparatus for stacking products

A device (10) for metering containers (14) for use in packaging machines is disclosed as including a pin system (11) which is pivotally mounted about its drive shaft (22) relative to a conveyor (54). Pin system (11) includes a driven flexible member in the form of cross bars (16) mounted to a roller chain (18) in a generally elliptically shaped endless loop, with the pins (12) extending form the cross bars (16) and being operatively attached to cam followers (20) thereby. The elliptically shaped endless loop is supported by a cam support (24) extending between drive and idler sprockets (28, 32) for continuously changing the pitch angles of the pins (12) along a portion of the endless loop. The pin system (11) is variably positioned relative to the conveyor (54) by pivoting the pin system (11) about the drive shaft (22) such that the containers (14) initially contact the pins (12) at different segments of the endless loop portion along the cam support (24) and sprockets (28, 32) and are inserted into the windows between adjacent containers (14) to allow the device (10) to be easily and quickly changed over to meter different sized containers (14). In the preferred form, the pin system (11) is pivoted by a crank arm assembly (40, 42) which is pivoted by a worm gear drive (46, 48) rotated by a hand wheel (52).

Container metering device

An animal restraining device comprised of a rigid frame pivotally supporting a pair of diverging horizontal outwardly extending support arms each of which carries a sliding block bearing a loop of flexible material which extends outwardly beyond the outer end of the arm and which is drawn inwardly by foot-actuated cable means into cooperative limb-engaging position with the end of its supporting arm. Adjustable spacing means extends between the two support arms and downwardly facing bracket means for readily mounting the frame upon a vertical panel is carried at the back side of the frame.
