BRIEF SUMMARY
DESCRIPTION
This invention relates to a cover apparatus designed for encircling and protecting a plurality of weighing machines.
The cover apparatus is designed for protecting a plurality of weighing machines arranged in a circular or similar predetermined pattern, acting as sound- and dust-proofing means for the weighing machines. The conventional cover apparatus for weighing machines is composed of panels arranged as a slide or door or designed as a circular cover. The slide-type apparatus is defective in that stopper means cannot be provided because of the complicated inside structure of the cover. The door-type apparatus tends to be bulky because of the space required for door rotation. Moreover, with the slide-type apparatus, the slide is simply shifted to one side and the apparatus cannot be opened on all sides simultaneously. With the door-type apparatus, a complex structure is required to open the doors fully on all sides. In the case of the circular slide-type apparatus, it is not necessary to provide such additional space or stopper means, but the structure is not of the type to permit opening of all sides simultaneously.
Certain weighing machines arranged in a circle may be tilted outwardly, that is, in the direction of the surrounding cover, to facilitate cleaning or inspection of the inside structure. Hence, with the cover apparatus that cannot be opened on all sides, the weighing machines cannot be tilted simultaneously, but only those machines which have been exposed by the opening of the associated side panels can be tilted at a time, which means a complicated operation and a lower operational efficiency.
The present invention contemplates to provide a cover apparatus devoid of these inconveniences.
According to one aspect of the present invention, plural weighing machines are encircled by a cover and inner and outer rails are provided around the weighing machines arranged in a circle. Plural arcuate inner covers and plural arcuate outer covers are movably mounted on the inner and outer rails, respectively, said inner and outer covers providing a continuous circular enclosure having stepped connecting portions at the side edges of the covers. The weighing machines may be enclosed easily in a sound- and dust-proof manner. Since the inner and outer covers may be movable in the manner of a sliding door along the inner and outer rails, respectively, the inner and outer covers can be overlapped for desired length. An open surface of any desired opening angle up to a maximum angle of 180.degree. can be realized at any desired position along the circumference subject to circular displacement of the inner and outer covers. Hence, the inside structure of the cover can be exposed to the outside as desired to permit prompt cleaning or inspection of the inside structure. Stopper means as required in the conventional covers or doors may be dispensed with, while the space so far required for rotary doors may be minimized because the inner and outer covers need to perform only a circular motion. In addition, the manufacture or mounting of the cover apparatus may be simplified and the apparatus may be handled conveniently.
According to another aspect of the present invention, the weighing machines are tiltable outwards and arranged in a circle. The weighing machines are surrounded by a multi-sided enclosure and each of a plurality of cover sections making up each side of the enclosure is formed by plural pairs of panels that are connected to each other by hinges. Thus each cover section constituting the cover surface may be closed tightly by the operation of hinged panels with complete sound- and dust-proofing effects. By virtue of the hinged panel structure, each cover section can be opened completely, so that the weighing machines can be tilted to permit the cleaning or inspection to be carried out easily and promptly. Stopper means as required in the conventional covers or doors may be dispensed with, while the space so far required for rotary doors may be minimized. The structure may be made simpler t
