Definitions

  • the present invention concerns a weighing-out apparatus of the kind which is equipped with an annular row of weighing stations, each with a weighing arrangement with a weighing cell in which a weighing bin with openable bottom is suspended.
  • a so-called combination weighing-out apparatus where over each of the weighing bins there is disposed a receiver-container, in that this ring of receiver-containers receives portions of the items to be weighed from an overlying, radially-extending conveyor system for filling down into the associated weighing bins as soon as these are available.
  • the weighing bins are activated individually for emptying down into an underlying, common re-tricving funnel, in that control equipment hereby determines which combinations of a small number of weighed part-portions can together provide a final portion of a desired size, so that delivery of said final portion can then be effected from the receiving funnel .
  • Other criteria for the controlling of the weighed material from the weighing bins can be envisaged, which in the present context is of no importance.
  • the important factor here is the structural configuration of the weighing bins in an outer annular area of the weighing apparatus, where these bins are potentially exposed to external influences, for e- xample by an operator wanting to adjust something or other at a given weighing bin inadvertently pushing on an adjacent corner of a neighbouring weighing bin.
  • the weighing bins in the individual weighing stations be connected with the associated weighing cells in such a manner that they are resiliently turnable in a normal plane on their axis connection with the weighing cell. If external pressure is applied on an outer side corner of a weighing bin, the bin will thus merely be resiliently turned out from its normal position without this having any significant effect on the mechanical stability between the weighing cell and the weig- hing bin. The weighing bins can thus be exposed to quite strong external influences without compromising the weighing accuracy.
  • fig. 1 is a schematic, perspective section view of a weighing-out apparatus according to the invention
  • fig. 2 is a more detailed view of a weighing bin suspension therein
  • fig. 3 is a horizontal section through a part of this.
  • the apparatus shown in fig. 1 has a number of weighing bins 2 arranged in an annular row and suspended in respective weighing cells in the weighing-cell housings 4 on support plates 5.
  • the bins are provided with an openable bottom flap 6, so that they can be opened to allow the weighed goods to fall down into an underlying common funnel 8 leading to a not-shown emptying area for weighed goods from several of the bins2.
  • a receiving bin 10 which can receive weighed goods from an associated delivery conveyor 14, e.g. a vibratory feeder, which is arranged in a controlled manner to deliver an amount of goods more or less corresponding to the desired part portions to the container 10.
  • a control unit can thus determine which portions together best constitute a desired measured weight, and on this basis the relevant weighing bins are opened for common delivery to the funnel 8.
  • the weighing bins can be suspended on a support frame 20, which via a lower crossbar 22 is fastened to a support block 24 on the lower end of a support pin 26 which extends downwards from the weighing cell housing. Inside the housing 4, this pin is in direct operati- ve connection with a not-shown weighing cell 27.
  • the support block 24 is arranged on the pin in a pivotable manner and, as shown in fig. 3, in this pivot connection there is inserted a resili- ently yielding latching element, e.g. a spring-loaded wedge lock 28 which secures the bar 22 in its normal position, but which, however, allows it to yield of the bin 2 is exposed to an inwardly-directed pressure on one of the outwardly-facing corners, so that it will be only a limited and controlled twisting effect which is transferred to the support pin 26. This will also occur with a side pressure on the outer end of the bin.

  • the invention is not limited to the shown embodiment, in that in principle the desirable resiliency can be established at any point in the relevant transfer system. Moreover, it is not necessary for the bins to be arranged in an annular row, in that it is also known to arrange them in straight rows, and the resiliency can possibly be arranged in other or further directions.

Abstract

L'inconvénient des appareils de pesée dotés d'une rangée annulaire de bennes de pesée saillantes présentant un fond pouvant être ouvert, réside dans le fait que les opérateurs et les personnes de l'entretien peuvent heurter par inadvertance les coins des bennes, les raccords mécaniques entre les bennes de pesée et leurs capteurs de pesage pouvant être ainsi exposés à des contraintes de torsions très importantes. Il serait possible de prévoir divers types de moyens de support, mais l'invention concerne une solution plus appropriée qui consiste en ce que les récipients de pesage sont suspendus de sorte qu'ils puissent être mis dans une position autre que leur dans position normale. Ainsi, lors de chocs importants, ils produiront des forces de rotation importantes sans les transférer au raccord au capteur de pesage.
