A multi-plane scanner having a dual plane scanner with a horizontal window and a vertical window and a load cell/weigh platter weighing apparatus such that the weigh platter itself is a dual plane object with vertical and horizontal sections. The size and orientation of the planes of the weigh platter correspond to the size and orientation of the scan windows of the dual plane scanner, and each plane of the weigh platter has a transparent area (typically central), or “platter window”, corresponding to a respective scan windows of the scanner for allowing transmission of scanned optical beams and optical barcode signals through each of the planes of the weigh platter. The platter is sufficiently rigid to permit accurate weighing whether the object being weighed is placed solely on the horizontal section of the platter or in part on the vertical section. The vertical and horizontal sections of the platter are sealed together to prevent passage of debris therebetween.

This application is a insures ensures rigidity sufficient to bear the weight of an object being weighed and sufficient to maintain its two-plane geometry and prevent the vertical scanner housing portion 46 from interfering with the weighing process. One such construction would be the incorporation of stiffening ribs 50 into the structure of the platter 6.
Also depicted in
The two-plane weight platter embodiment solves two of the problems discussed in the background section. First, the vertical section 38 of the weigh platter 6 at the side adjacent the vertical scan window 10, being connected to and moving with the horizontal section 20, prevents debris from falling therebetween and under the weigh platter 6 on that side and obstructing the horizontal scan window. Second, the vertical section 38 of the weigh platter 6 prevents the object being weighed from coming into contact with the vertical scan window 10, so the vertical scan window 10 will not interfere with the weighing process.
The weigh platter preferably has bottom extensions which extend below the planar surface of the window 14 to prevent debris or liquids from contacting the window 14. Moreover, the side surfaces (i.e. both lateral sides and the side next to the checker) of the horizontal scan housing portion 24 are sloped to channel debris and liquids down and away from the window 14. The sides of the weigh platter 6 (such as the stiffening ribs 50) may extend downwardly to provide additional baffles in further inhibit debris or liquids from contacting the window 14. Alternatively, the downwardly extending sides may be disposed in a trough and be provided with additional spill control and air gap maintenance thereby as disclosed in U.S. Pat. No. 5,410,108, which is incorporated by reference.
The multiple plane weigh platter 6 also facilitates weighing of oversized objects. With existing weigh platters, if the length of an object to be weighed exceeds the length of the horizontal weigh platter, the object may come in contact with the housing or the counter resulting in inaccurate weight measurement.
To achieve potential reduction in size and material/manufacture cost, the load cell 4 may be incorporated directly into an upper section of the horizontal scanner housing portion 24, instead of comprising a separate subassembly. The weigh platter 6 is borne by the load cell 4 either directly or via a spider such as in alternate embodiments described below. In so called “spiderless” designs, the weigh platter itself is made sufficiently rigid to bear the object being weighed. By combining the weighing device and scanner in a single unit the overall size of the scanner/weighing device combination may be reduced compared to earlier devices at potentially reduced cost of material and/or manufacture.
The apparatus 1 of
Though a single load cell and pin mounting design may be preferred, the apparatus may be configured with multiple load cells.
Alternatively, a spider may be rigidly but removably connected to the load cell, which in turn hears the two-plane weigh platter.
Alternatively, the load cell upon which the spider is mounted may be placed next to or below the scanner housing portions and rigidly connected to the spider by suitable horizontal or vertical support members, respectively.
Spider designs may also incorporate multiple load cells. In the apparatus 401 of
In each of the above embodiments, the load cell may be located within the scanner envelop envelope (such as load cell 205 in
The disclosed embodiments of the multiple plane weigh platter may be combined with any suitable weighing device and with any multiple plane optical reading device without altering the concept of the present invention. Alternately, the platter may merely comprise a cover for a multi-plane scanner (i.e. a scanner having no scale). In the “no-scale” embodiment, the multi-plane cover would still provide spill and mechanical protection for the internal components, but may not require as stiff a construction as does the weigh platter scale version.
The embodiments disclosed may be modified in various ways without departing from the fundamental inventive concept presented hereinabove. Further modifications may include, but are not limited to: the number of scan planes and weigh platter planes; the method of manufacturing the weigh platter; the mechanical connection between the weigh platter and the weighing device; the particular nature of the weighing device; and the positioning of the weighing device (integral to the scanner or as a separate subassembly).
Though the multi-plane weigh platter has been shown and described with respect to a laser scanner such as the Spectra-Physics MAGELLAN™ scanner, it is intended that scanner upon which the weigh platter is constructed may comprise any sort of data reading device including scanning laser beam(s), CCD, video, LED, or the like.
Though the multi-plane weigh platter has been described as useful for multi-plane scanner, it may also be used in a single plane (either horizontal or vertical) that may have additional components. Envision for example a scanner/scale 1 of
Though the weigh platter has been described with respect to dual-plane scanners, additional scan planes can be accommodated. For example in
Thus, a multiple plane optical scanning system has been shown and described herein which incorporates a multiple plane spiderless weigh platter and an integrally mounted load cell. Though certain examples and advantages have been disclosed, further advantages and modifications may become obvious to one skilled in the art from the disclosures herein. The invention therefore is not to be limited except in the spirit of the claims that follow.
