Abstract
Preformed articles such as cardboard disks are stacked in a feeding unit 10, 12 and fed along a series of driven rollers 15. The preformed articles are then transferred to a first continuous conveyor belt 28 and by a series of three pressure drives 30, 31, 32 into two brush assemblies 35, 36 which brush away any fibrous debris which may be attached to the preformed articles. Each of the preformed articles is subjected to streams of compressed air which remove the remaining loose debris. The preformed articles are then directed onto a second continuous conveyor belt 40 and collected at the end of the second belt 40. <IMAGE>
Description
APPARATUS FOR CLEANING PREFORMED ARTICLES
The present invention relates to an apparatus for cleaning debris and waste material from preformed articles created in the forming stage, in particular to preformed articles of a cardboard material.
When cardboard is cut an amount of fibrous debris is created. The amount of debris will increase when the cutting tool becomes blunt. Resharpening of the cutting edge of the cutting tool is time consuming and expensive.
If the cardboard articles are coloured or have coloured print on them, additional coloured fibre debris is created.
A known solution to the above problem is to use an anti-static device to remove the debris. Unfortunately, this solution cannot be used where the articles are coated with a polyethylene film which is usually adhered to the articles by electrostatic charge. If an anti-static device is used to remove debris from coated articles, the film delaminates partially or wholly.
Debris of any kind is particularly undesirable when the articles are to be used for the packaging of food.
It is an object of the present invention to seek to alleviate the above disadvantages.
Accordingly, the present invention provides an apparatus for removing debris from preformed articles comprising feeding means for feeding the articles along the apparatus, means for brushing each of the articles and means for directing at least one stream of compressed gas at each of the articles as they are fed along the apparatus, whereby the articles are subjected to at least one brushing operation and to at least one directed stream of compressed gas.
Preferably, the brushing means include at least two brush assemblies and the gas directing means include a plurality of compressed air jets so that the preformed articles are brushed twice and are subjected to a plurality of high powered streams of compressed air.
Advantageously, the feeding means include a feed funnel, a feed adjuster to meter the rate at which the preformed articles are fed along the apparatus, and a plurality of rollers for conveying the articles.
Preferably, a first conveyor belt is provided downstream of said rollers and a plurality of pressure drives for guiding the articles towards the brushing means.
Conveniently, a second conveyor belt is provided downstream of the first conveyor belt, the second conveyor belt being operable to run at a slower speed than the first conveyor belt so as to collect the cleaned articles thereon.
Advantageously, a shingling assembly is juxtaposed the second conveyor to meter the cleaned articles being fed onto the second conveyor, and counting means are provided to record the number of articles cleaned.
The invention also provides a method of removing debris from preformed articles, comprising feeding each of the articles along a track, brushing each article to loosen the debris and directing one or more streams of compressed air at each article to remove completely the debris from the article.
The invention will now be described more particularly with reference to the accompanying drawings, which show, by way of example only, one embodiment of cleaning apparatus according to the invention. In the drawings:
Figure 1 is a plan view of the apparatus;
Figure 2 is a sectional side elevation taken along lines
II-II of Figure 1.
Referring to the drawings, preformed articles such as cardboard disks for example are stacked in a feeding unit which comprises a feed funnel 10 and a feed adjuster 12 to meter the rate at which the preformed articles or disks are fed onto a series of driven rollers 15. The rollers 15 are driven by a continuous belt 16 which is powered by a main motor 19 via a roller 20 located on a support frame 25. The preformed articles (not shown) are then transferred to a first continuous conveyor belt 28. The articles are guided by a series of three pressure drives 30, 31, 32 which guide the articles into two brush assemblies 35, 36. The action of the brushes in the brush assemblies 35, 36 brush away any fibrous debris which may be attached to the preformed articles. Each of the preformed articles is subjected to streams of compressed air which remove the remaining loose debris.The preformed articles are then directed onto a second continuous conveyor belt 40 which is narrower than the first belt 28 and runs at a slower speed as a result of the reduction gear 42. A shingling assembly comprising a shingling wheel 44 and a counter 46 which meters the proximity of one article to the next and detects the number of articles which have been cleaned, respectively. The cleaned articles are then collected at the end of the second belt 40.
Emergency stop controls are provided to meet safety regulations.
The apparatus is particularly useful for cleaning preformed articles such as cardboard lids used in ice cream cone wrapping operations. In a cone wrapping operation, a triangular sheet of covering material is wrapped about the conical side of the cone and ice cream top and a lid is placed on top of the ice cream top to complete the wrapping. Because of food industry. regulations, these lids have to be dust and fibre free.
The apparatus of this invention is particularly suited for overcoming this problem. The light physical cleaning of the lids by the apparatus removes the offending dust and fibre but does not interfere with the polyethylene coating.
It will of course be understood that the invention is not limited to the specific details described herein, which are given by way of example only, and that various modifications and alterations are possible within the scope of the invention as defined in the appended claims.
