BE1014419A6 - Weighing device uses supporting structure and beam-type load cells to connect structure to base frame in mobile weighing system - Google Patents

Abstract

An auxiliary element (21) is used to connect a load cell (1) to the supporting structure (2) and the load cell is bolted to the base plate (22), while the auxiliary element is connected to the supporting structure through a universal joint. The load cell is fitted into a rectangular opening in a solid block and a secondary auxiliary element (26) can also be bolted to the load cell.

  Force introduction for a weighing system Description: A force introduction (2) on a weighing sensor (1) (so-called load cell) is always carried out according to a method as prescribed by the weighing sensor manufacturer.



  If this does not happen, you risk recording bad results.



  It is logical that a weighing sensor (1) is constructed according to a specific construction method and that the location and method of the force introduction (2) on that weighing sensor is specific.



  If during weighing due to circumstances the weighing system moves due to the possible mobile nature of the weighing system and due to possible shocks, tilting or torsion, the force introduction (2) on that weighing sensor (1) could change slightly and therefore the measurement results and especially the repeatability unfavorable

 to influence. The invention provides for the application of a flexible mass, e.g. rubber or artificial rubber, which, as it were, brings the weight sensor (1) with its applied load force introduction (2) together in a flexible whole as if it is and remains 66n homogeneous togetherness under all circumstances.



  Bringing together flexible mass with the weighing sensor and the force introduction can be done by fusing, vulcanizing, sticking or clamping.


    

Claims (4)

Conclusions: A mechanical force introduction (2), applied to a weighing sensor (1) (so-called load cell), carried out in such a way that there is contact between them which must try not to become detached from each other in any direction, but where there is danger consists of that in the force introduction (2), due to mobile circumstances, parts would move little or move relative to the weight sensor (1), with the result that the force introduction (2) t. o. the weighing sensor (1) changes slightly and erroneous weighing results could occur, characterized in that the weighing sensor (1) and its force introduction (2) are additionally held together by a flexible mass (3) and the whole as a togetherness, albeit in flexible form, is and remains under all circumstances. Second conclusion: The invention according to the preceding claim, characterized in that the flexible mass (3) is rubber or artificial rubber which makes a connection between the weighing sensor (1) and the load force introduction (2) by changing its liquid form (e.g. solidification due to chemical reaction) ) to a fixed flexible form and, as it were, encapsulate the force introduction (2) and the weight sensor (1) together in a flexible mass. Third conclusion: Invention as claimed in one or more of the foregoing claims, characterized in that the flexible mass (3) makes a connection between the weighing sensor (1) and the load force introduction (2) or a part thereof, brought about by sticking, vulcanizing, clamping and / or hold. Fourth conclusion: The invention as claimed in one or more of the preceding claims, characterized in that the component (4) of the force introduction (2) which ultimately determines the force introduction on the weighing sensor (1), the contact voltage pressure, as a fastening bias with the weighing sensor (1), can control by making more or less compression of the flexible mass (3) present. Fifth conclusion: Invention according to one or more of the preceding claims, characterized in that the component (5) of the force introduction (2) makes the safeguard for maintaining a constant position of the force introduction t. ov of the weighing sensor (1) is adjustable for more or less contact voltage pressure by more or less compression of available flexible mass (3) Sixth conclusion: Invention according to one or more of the preceding claims, characterized in that the weighing sensor (1) on its load-receiving side has a non-vertical bore or space (8) in which a lock (6) and flexible mass (3) causes the upper part (4) of the force introduction (2) which the force introduction ultimately exerts on the weighing sensor (1) to position and that position mandatory in all circumstances. Seventh conclusion: The invention as claimed in one or more of the preceding claims, characterized in that the weighing sensor (1) is provided under its load-receiving side with a locking device (7) for the force introduction, in combination with the flexible mass (3) present  <Desc / Clms Page number 3>  Legend and figure description: 1 = Weighing sensor 2 = Force introduction 3 = Flexible mass 4 = the part of the force introduction (2) that finally determines the force introduction on the weighing sensor (1) 5 = the part of the force introduction (2) that makes sure that the weight sensor (1) does not come loose with the force introduction (2) ) from each other 6 = Locking shaft 7 = Locking K = Force t. g. v. the mass to be measured
