Abstract
Embodiments of the present invention provide systems and methods for retrofitting a thermoforming trim removal system to utilize a perforated collection bag to collect waste instead of a rigid collection bin. The perforated collection bag can be made of inexpensive, disposable polymeric materials, including those that can be recycled in the same waste stream as the waste, thereby permitting full bags to be discarded without first emptying their waste contents.
Claims20
A system for retrofitting a waste removal system, the waste removal system having a housing with one or more vacuum inlets disposed therein, a lid coupled to the housing, a rigid collection container disposed within the housing and adapted to collect waste, vacuum hosing coupled to the one or more vacuum inlets, and a vacuum source operatively coupled to the housing to suction waste through the vacuum hosing and the one or more vacuum inlets into the rigid collection container, the system comprising:
- a perforated collection bag adapted to be placed inside of the housing instead of the rigid collection container, the perforated collection bag having an opening through which waste can enter the perforated collection bag, the perforated collection bag having a bottom located opposite the opening;
- an extension having one or more vacuum inlets disposed therein, the extension being adapted to be releasably coupled to the lid, the extension being adapted to be releasably coupled to the housing to secure the perforated collection bag within the housing such that the one or more vacuum inlets disposed in the extension are positioned above the opening of the perforated collection bag, the one or more vacuum inlets disposed in the extension being adapted to be coupled to the vacuum hosing;
- and
- one or more objects adapted to block airflow through the one or more vacuum inlets disposed in the housing.
A waste removal system, the waste removal system comprising:
- a housing with one or more vacuum inlets disposed therein;
- one or more objects coupled to the vacuum inlets disposed in the housing, the one or more objects adapted to block airflow through the one or more vacuum inlets disposed in the housing;
- an extension coupled to the housing, the extension having one or more vacuum inlets disposed therein, the one or more vacuum inlets disposed in the extension being adapted to attach to vacuum hosing;
- a lid coupled to the extension;
- a vacuum source coupled to the housing;
- and
- a perforated collection bag disposed within the housing, the perforation collection bag having an opening through which waste can enter and a bottom opposite the opening, the opening being disposed below the one or more vacuum inlets disposed in the extension.
A method for retrofitting a waste removal system, the waste removal system having a housing with one or more vacuum inlets disposed therein, a lid coupled to the housing, a rigid collection container disposed within the housing, vacuum hosing coupled to the one or more vacuum inlets, and a vacuum source operatively coupled to the housing to suction waste through the vacuum hosing and the one or more vacuum inlets into the rigid collection container, the method comprising:
- removing the rigid collection container from the housing;
- inserting a perforated collection bag into the housing;
- attaching an extension to the housing, the extension having one or more vacuum inlets disposed therein;
- attaching the lid to the extension;
- connecting the vacuum hosing to the one or more vacuum inlets disposed in the extension;
- and
- blocking airflow through the one or more vacuum inlets disposed in the housing.
