Material feeding apparatus

Abstract

A material feeding apparatus has a vibration absorbing construction, in which an impulse and vibrations from a press apparatus, etc. are hard to transmit to a material feeding equipment, etc., and includes an inner housing that accommodates therein the material feeding equipment, and an outer housing connected to the inner housing through a vibration absorbing member. A vibration restricting member is provided between the housings to restrict the degree of freedom of vibrations, which are transmitted to the inner housing through the vibration absorbing member when an impulse force acts on the outer housing, only in a vertical direction. The vibration restricting member includes an upper plate member, upper and lower surfaces of which are interposed between a top wall of the outer housing and a top wall of the inner housing, and a lower plate member, upper and lower surfaces of which are interposed between a bottom wall of the outer housing and a bottom wall of the inner housing.

1 . A material feeding apparatus comprising an inner housing that accommodates therein a material feeding equipment, an outer housing surrounding the inner housing and connected to the inner housing through a vibration absorbing member, and a vibration restricting member provided between the inner housing and the outer housing to restrict the degree of freedom of vibrations, which are transmitted to the inner housing through the vibration absorbing member when an impulse force acts on the outer housing, in one direction. 
   
   
       2 . The material feeding apparatus according to  claim 1 , wherein the vibration restricting member restricts the degree of freedom of vibrations transmitted to the inner housing in a vertical direction. 
   
   
       3 . The material feeding apparatus according to  claim 2 , wherein the vibration absorbing member includes an upper vibration absorbing member interposed between a top wall of the outer housing and a top wall of the inner housing and a lower vibration absorbing member interposed between a bottom wall of the outer housing and a bottom wall of the inner housing, and the vibration restricting member includes an upper plate member, upper and lower surfaces of which are interposed between the top wall of the outer housing and the top wall of the inner housing, and a lower plate member, upper and lower surfaces of which are interposed between the bottom wall of the outer housing and the bottom wall of the inner housing. 
   
   
       4 . The material feeding apparatus according to  claim 1 , wherein the outer housing is fixed to a housing of a press apparatus. 
   
   
       5 . The material feeding apparatus according to  claim 1 , wherein the material feeding equipment comprises a main roll and a sub-roll, which interpose therebetween a material to convey the same, and the main roll is driven by a servomotor.
