Container processing machine

摘要

There is disclosed a container processing machine comprising a material handling surface for handling a sheet-like material through suction and a vacuum source in fluid connection with said material handling surface, the machine including means for detecting and transmitting a value of pressure of the gas being suctioned; a controllably operable flow valve; a control unit operatively connected with said detection and transmission means and with said flow valve; said detection and transmission means and said flow valve being arranged between said vacuum source and said material handling surface; said control unit being programmed to adjust the degree of opening of said flow valve in response to a signal which is a function of at least said value of pressure.

1. A container processing machine comprising:
a material handling surface to handle a sheet-type material through suction; a vacuum source in fluid connection with said material handling surface; means for detecting and transmitting a value of pressure of the gas being suctioned; a controllably operable flow valve; a control unit operatively connected with said detection and transmission means and with said flow valve, wherein said detection and transmission means and said flow valve are arranged between said vacuum source and said material handling surface; and debris intercepting means arranged downstream from said material handling surface, said detecting and transmission means being located substantially at said debris interceptor with which they are fluidically connected by a sampling duct; said control unit being programmed to adjust the degree of opening of said flow valve in response to a signal which is a function of at least said value of pressure.
