Description

Description: TECHNICAL FIELD The present invention relates generally to a glass recycling machine. The present invention preferably relates to an apparatus for regenerating an automotive windshield.

BACKGROUND ART In order to efficiently recycle or dispose of windshields for automobiles, it is desired to crush the glass. In particular, many machines have been developed for crushing empty glass containers. These machines typically include an inlet opening through which the glass container is inserted, and an outlet opening through which broken glass shards and glass dust are discharged. To complete the breaking of the glass, these machines usually
Either a destruction device or a hammermill type destruction device is used.

Existing glass grinding machines are, for several reasons,
It is not well adapted to reclaim or dispose of automotive windshields. First, such devices are extremely large and are typically found only in large reprocessing plants. In general, car garages do not always have access to such reprocessing machines. Second,
Typical dimensions of the entry opening for the glass to enter the grinding machine are those dimensions that require the windshield to be broken into smaller pieces before being inserted into the opening.

Third, automotive windshields consist of two layers of glass and a plastic liner that is firmly bonded between the two layers of glass. Because of this structure, the glass must first be separated from the plastic liner material before the glass can be recycled.

A fourth problem with existing equipment used to reclaim automotive windshields is that machines using shatter-type equipment are prone to jamming when plastic is plugged into the machine exit. It is. Like this
A plastic liner sandwiched between two layers of glass hinders the use of this type of machine.

Finally, after the glass has been separated from the surface of the plastic liner, the two materials must be separated for recovery and regeneration because they are mixed.

Therefore, a glass plate of the size of a windshield for automobiles can be accepted. Therefore, it is desired to provide an apparatus that does not require the glass plate to be crushed before the regeneration process, that is, the disposal process is started.

It is also desirable to provide an apparatus that can separate two layers of glass from the inner plastic liner material and then separate the two materials for recovery.

DISCLOSURE OF THE INVENTION It is a feature of the present invention to provide a compact automotive windshield reclaiming machine that can be used in the field, thereby eliminating the need to transport the windshield to an independent reclaiming plant. is there. Due to the small and compact dimensions, the reprocessing machine of the present invention can be installed in a typical car or glass repair shop without occupying a large and expensive working space. The compact, space-saving features are also valuable for central reprocessing plants.

It is a second aspect of the present invention to provide a glass reclaiming machine that has an inlet opening to receive the full width of the automotive windshield, thereby eliminating the need to crush the glass sheet before using the machine. It is a feature. The glass sheet is drawn into the machine by double feed rollers, each having a shaft at each end. These shafts extend through openings in the housing side plates and rotate within offset loaded bearings. The lower offset is fixedly mounted on the housing side plate, while the upper offset is slidably mounted on the housing side plate so that the upper roller separates and accepts the thickness of the windshield. Has become.

It is another feature of the present invention to include a fixed breaking bar and an adjustable rotating impactor shaft on which a plurality of flexible impactors are mounted. As the glass sheet is fed into the machine by the feed rollers, the glass sheet passes over the fixed breaking bar and into the impact line of the rotary flexible impactor. The combination of the fixed breaking bar and the rotating impactor acts to separate the glass from both sides of the inner plastic liner. The glass is hammered to fine gravel and sand sized particles, and the plastic liner remains much larger debris.

It is a further added feature of the present invention to provide a swinging sieve below the rotating impactor shaft. Glass granules of much smaller size pass through a rocking sieve into a glass collection container below the unit. The larger plastic debris remains on the rocking sieve and is carried from the unit into another collection bin.

These and other effects of the present invention will become more readily apparent when the best mode for carrying out the invention shown below is read and the drawings are referred to.
