Abstract:
A food mixer comprises a base, a supporting structure or column upstanding from the base and an arm projecting from the upper end of the column and carrying a mounting member for a mixing tool. The column is provided with a vertically extending V-section channel on its bowl-facing side which, in use, receives part of the periphery of the mixing bowl so that the necessary horizontal extensions of the head from the column is minimized. The mixing bowl is supported on a mixing bowl support vertically movable on the column to bring the bowl up to the mixing tool and lower the bowl therefrom. Except in the fully lowered position of the bowl support, the bowl is held captive on the bowl support by a pin which is extended upwardly through a hole in a flange of the bowl, the flange being received in a slot in the bowl carrier. The pin is carried by a lifting mechanism for the bowl support and is arranged with a degree of vertical lost motion relative to the bowl support, thus ensuring that the bowl is automatically locked into the bowl support before any lifting movement takes place and is not released until the bowl support has been fully lowered.
Abstract:
A method and apparatus are disclosed for printing and applying labels to packages which can vary in height over a large range, for example from a minimum height of 0.5 inches to and including a maximum height of 5.5 inches. A label applier is pivotally mounted and gravity biased toward a lowermost position adjacent a package conveyor with the label applier being upwardly pivoted by packages passing thereunder to accommodate the wide range of package heights. Packages are sensed on the conveyor as they move toward the label applier which prints and holds labels with the adhesive coated sides of the labels unexposed until the expiration of periods of time based upon package sensing. By timing label application to occur upon the expiration of such time periods, the labels are applied to preferred areas of the upper surfaces of the packages adjacent either the leading side edges or the trailing side edges of the packages as defined by direction of package conveyance. The label applier also can move laterally relative to the package conveyor to further define the preferred areas of label application on the top surfaces of the packages.
Abstract:
A steam generator is formed by a plurality of similar heat accumulator units stacked vertically. Each heat accumulator unit of the stack has an orientation different than any adjacent heat accumulator unit so that multiple heat accumulator elements of the each heat accumulator unit align with respective open spaces of any vertically adjacent heat accumulator unit.
Abstract:
An elevator-type package wrapping machine which determines as by premeasurement the length of packages fed at a first level thereto, comprises a film gripper for initially drawing a fixed length of stretch film horizontally from a supply roll to a fixed stop position in the machine. While the film is held by the film gripper, a package which has one edge thereof at a predetermined distance from the fixed stop position is elevated to a second level above the level of the gripper into the film such that the package draws a first addition to the length of film drawn by the gripper, according to the height of the package. A vertically-moving horizontal bar is moved into contact with the film remote from the fixed stop position to pull a second additional length of film from the film source in accordance with the measured package length, if required. A film cutter is provided for severing the film from its source while the film is stationary, following which, film side and rear underfolders fold the lateral edges of the film and the rear edge of the film extending from the film source under the package. The underfolders and horizontal bar are operated independent mechanisms, enabling separate timing of each. The package is then pushed essentially horizontally in an outfeed direction, at which time the gripper releases the film and allows the released portion to be underfolded beneath the package as it is pushed. The package is then passed over a heated belt to seal the overlapping edges of the film beneath the package.
