Device for filling containers by weight, the device being fitted with an anti-vibration member

Abstract

A device for filling containers by weight, the device comprises: a filler spout carried by a structure and having a delivery orifice; a container support member extending on one side of the filler spout, the container support member being associated with a weight sensor arranged at a level that is higher than the delivery orifice; and a connection arm having a first end fastened to the structure and a second end fastened to the container support member at a level below the weight sensor, the connection arm having two folding portions configured to enable effortless folding about mutually parallel horizontal axes, while providing a connection that is rigid against forces in a horizontal plane.

What is claimed is: 
     
         1 . A device for filling containers by weight, the device comprising: a filler spout carried by a structure and having a delivery orifice; and a container support member extending on one side of the filler spout, the container support member being associated with a weight sensor arranged at a level that is higher than the delivery orifice, and including a receptacle holder portion arranged below the delivery orifice, wherein the device includes a connection arm having a first end fastened to the structure and a second end fastened to the container support member at a level below the weight sensor, and wherein the connection arm includes at least one folding portion configured to enable effortless folding about a horizontal axis while providing a connection that is rigid against forces in a horizontal plane. 
     
     
         2 . A device according to  claim 1 , wherein the connection arm has two portions for effortless folding about two mutually parallel horizontal axes. 
     
     
         3 . A device according to  claim 1 , wherein the connection arm is arranged at the level of the container-holding portion. 
     
     
         4 . A device according to  claim 1 , wherein the connection arm comprises a strip of plastics material and the folding portion is defined by a V-groove. 
     
     
         5 . A device according to  claim 1 , wherein the structure is rotary, and the connection arm extends radially relative to a path traveled by the containers during filling. 
     
     
         6 . A device according to  claim 1 , wherein the support member includes a support plate connected to the weight sensor by a rod, and the connection arm is arranged at the level of the support plate. 
     
     
         7 . A device according to  claim 1 , wherein the container support member is merely placed on the weight sensor. 
     
     
         8 . A device according to  claim 1 , wherein the container support member comprises a rod engaged in a support tube carried by the structure, and the first end of the connection arm is rigidly connected to the support tube by a spacer. 
     
     
         9 . A device according to  claim 1 , wherein the weight sensor comprises: an elastically deformable bar having one end rigidly fastened to the structure and an opposite end that is cantilevered out, together with a sensing element associated with the elastically deformable bar to measure its deformation, and wherein the container support member has a top end connected to the cantilevered end of the elastically deformable bar.
