Description
.: ~
The present invention relates to receptacle for use in a pneumatic conveyer system.
BACKGROUND OF THE INVENTION
A number of pneumatic conveyer systems have been developed. United States Patent 2,556,058 was granted to William Boon in 1951 for an invention entitled ~Pneumatic Conveyer System . This system is described as being an improved conveying system for laundries, cleaning plants, textile processing plants and the like, which is suitable for conveying batches of damp weighty and bulky material and articles from a feeding position to a remote delivering position. United States Patent 3,951,461 was granted to Sergio De Feudiæ in 1976 for an invention entitled "Pneumatic Conveying Pipe System for Collection and Intermittent Conveyance of Different Types of Goods~. This system is described as being adapted to collect and intermittently convey goods of different kind, for example laundry, from different buildings and stories, for example in hospitals, hotels, and the like, to a central collecting station.
25Although both of the described references contemplate the conveyance of damp articles, such as laundry, neither address the problem of having a receptacle suitable for ~torage of damp articles. It is well known that if damp articles are left in storage for any period of time mildew begins to form and the articles emit an unpleasant odour.
SU~ARY OF THE INVENTION
35What is required is a receptacle for use in a pneumatic conveyer system.
According to the present invention there is provided a receptacle for use in a pneumatic conveyer system which L~ 3 includes an air impervious storage chamber having an interior with a top, a bottom, peripheral sidewalls, and an access opening sealed by a removable closure. An intake channel adapted to be connected to an intake pipe communicates with the interior of the storage chamber. A vacuum source conduit is adapted to be connected to a vacuum source. A mesh bag is suspended within the interior, such that articles entering through the intake channel are directed into the mesh bag.
The mesh bag is spaced ~rom the peripheral sidewalls thereby permitting a circulation of air from adjacent the peripheral sidewalls through the mesh bag upon activation of the vacuum source. A grid-form support is disposed in the interior and spaced above the bottom such that the grid-form support supports the mesh bag in spaced relation to the bottom thereby permitting a circulation of air from adjacent the bottom through the mesh bag upon activation of the vacuum source.
The receptacle, as described, provides an improved circulation of air which greatly reduces the formation of mildew.
Although beneficial results may be obtained through the use of the receptacle, as described, considerable time and labour can be saved if some means is provided for sorting articles as they enter the receptacle. Even more beneficial re~ults may, therefore, be provided by having the interior divided by a baffle into a first compartment and a second compartment. A deflector plate is pivotally mounted within first compartment of the interior adjacent the intake channel.
The deflector plate pivots between an operative position and an inoperative position. In the inoperative position articles pass through the intake channel into the first compartment and in the operative position articles passing through the intake channel strike the deflector plate and are deflected into the second compartment.
Although beneficial results may be obtained through the use of the receptacle, as described, it is important that there be ease of access to the contents of the mesh bag. Even more beneficial results may, therefore, be obtained when the mesh bag has a sidewall with an access opening extending therethrough. Fastening means are provided along opposed sides of the access opening whereby the access opening is selectively opened and closed.
Although beneficial results may be obtained through the use of the receptacle, as described, with a system of this type it is undesirable for the receptacle to be overfilled.
In such event the intake channel and attached intake pipe can become blocked. Pneumatic conveyance of articles is, of course, impossible when the intake pipe is blocked. Even more beneficial results may, therefore, be obtained by having a sensor positioned in the interior adjacent the top adapted to provide a signal when the interior is filled with articles to a predetermined level.
BRIEF DESCRIPTION OF THE DRAWINGS
These and other features of the invention will become more apparent from the following description in which reference is made to the appended drawings, wherein:
FIGURE 1 iB a diagrammatic section view of a pneumatic conveyance system.
FI~URE 2 is a perspective view, partially in section, of a receptacle constructed in accordance with the teachings of the present invention.
