Device for cutting plastic products provided in a continuous plastic band for use in the medical sector

Abstract

Devices for cutting interconnected plastic products for use in the medical sector provided in a continuous band of plastic, comprising a laser, a laser control system and an optical acquisition and data processing unit are disclosed. Devices for the manufacture of plastic products, such as fillable or filled plastic containers for use in the medical sector, comprising a device for cutting interconnected plastic products provided in a continuous band of plastic as well as a process for cutting interconnected plastic products provided in a continuous band of plastic are disclosed. The optical acquisition unit may determine positional data for the interconnected plastic products provided in the band. From the positional data a cutting pattern may be calculated and transmitted to the laser control system. According to this cutting pattern, the position, intensity and focal point of the laser may be controlled by the laser control system, which may comprise a focusing optic, a deflection means and a beam-forming means.

1 . A device for cutting plastic products for use in the medical sector provided in a continuous plastic band, comprising at least one laser, at least one laser control system, at least one optical acquisition and data processing unit, and a quality control device with an integrated pressure sensor for the detection of incorrect laser cuts. 
     
     
         2 . The device according to  claim 1  further comprising a system to compensate for long-term drift effects of the laser beam and the controllable deflection means 
     
     
         3 . The device according to  claims 1  or  2  wherein the plastic products are at least one of bottles, bags, containers or ampoules. 
     
     
         4 . The device according to  claims 1 ,  2 , or  3  further comprising a conveying unit for transport of the plastic products provided in the continuous band. 
     
     
         5 . The device according to  claims 1 ,  2 , or  3 , wherein the laser control system comprises at least one controllable focusing optic, at least one controllable deflection means and at least one beam-forming means. 
     
     
         6 . The device according to  claims 1 ,  2 , or  3  in combination with a device for producing plastic products according to the blow-fill-seal process.
