Abstract
The present invention relates to a weighing apparatus, more specifically, a base; A rod-shaped sensor unit which extends in a lateral direction from one side to the other side and deforms downward when the load is applied to the other side and generates an electrical signal proportional to the deformation amount, and extends in the lateral direction from one side to the other side It has a rod shape, which is disposed below the sensor part so as to face the sensor part, the bottom surface is connected to the support part in contact with the upper surface of the base, one side of the sensor part and one side of the support part, respectively, the other side of the sensor part A load cell including a connection part allowing the sensor part to be deformed by a distance from the support part by a predetermined distance; An upper plate positioned above the load cell and subjected to a load by a measurement object positioned above the load cell; And a load ball disposed between the upper plate and the sensor unit to transfer the load applied to the upper plate to the other side of the sensor unit, wherein the connection unit is integrally connected to the sensor unit and the support unit. It is about a weighing apparatus.
Description
The present invention relates to a weighing apparatus, and more particularly, to a weighing apparatus in which sensor characteristics are not degraded because the surface of the base in contact with the load cell does not settle even if the weight is repeatedly measured.
A weighing device is used for a scale for weighing an object to be weighed. That is, the weighing scale supports each of four to eight places on the lower surface of the upper plate on which various weighing objects such as automobiles and animals can be placed, and an electric signal proportional to the load applied when a load is applied. And a display device for calculating and displaying the weight of the weighed object by using the weighing device for generating the weight and the electrical signal generated from the weighing device.
Such a

The present invention has been made to solve the above-mentioned problems, and even if the weight of the weighed object is repeatedly measured, the base contacting the load cell does not settle, the boundary condition of the sensor does not change, and the initially set measurement value is constant. It is an object of the present invention to provide a weighing apparatus that can be maintained.
Weighing apparatus using a rod-shaped sensor unit according to the present invention for achieving the above object, the base;
A rod-shaped sensor unit which extends in the lateral direction from one side to the other side and generates an electric signal proportional to the deformation while the other side is deformed downward when a load is applied to the other side;
A support having a rod shape extending in a lateral direction from one side to the other side and disposed below the sensor portion so as to face the sensor portion, and having a lower surface thereof in contact with an upper surface of the base;
A load cell connected to one side of the sensor part and one side of the support part, the load cell including a connection part allowing the other side of the sensor part to be spaced apart from the support part by a predetermined distance or more;
An upper plate positioned above the load cell and subjected to a load by a measurement object positioned above the load cell; And
Is provided between the upper plate and the sensor portion of the load cell is provided with a load ball for transferring the load applied to the upper plate to the other side of the sensor portion,
The connection part is integrally connected with the sensor part and the support part.
In the weighing device,
Preferably, the load cell has a "c" shape.
In the weighing device,
The load cell may be fixedly coupled to the base by a first bolt through which the connection part is connected to the base and a second bolt that is connected to the base through the support part.
In the weighing device,
It is preferable that the other side of the support portion is formed to extend longer in the lateral direction than the other side of the sensor portion.
In the weighing device,
The second bolt,
It is preferable that the other side of the support penetrates a portion extending from the other side of the sensor unit.
In the weighing apparatus according to the present invention, since the load cell is generally formed in a "c" shape and the load cell is mounted on the base, even if the weight is repeatedly measured, no settlement occurs on the upper surface of the base and the boundary condition of the sensor is maintained. It does not change and has the effect of keeping the initially set measurement constant.
Hereinafter, with reference to the accompanying drawings, a weighing apparatus according to a preferred embodiment of the present invention will be described as follows.
The invention according to the present embodiment relates to a platform type weighing apparatus capable of measuring the weight of various types of weighed objects having a flat plate. Specifically, the present invention relates to a weighing device capable of measuring the weight of various raw materials, finished products, and animals, and the like, and as shown in FIGS. 3 and 4, the
