CARDING MACHINE CLEANER PLENUM Filed Oct. 21, 1968 INVENTOR. JOHN E. CROWLEY, JR.
A TTORNE Y United States Patent Oflice 3,520,028 Patented July 14, 1970 3,520,028 CARDING MACHINE CLEANER PLENUM John E. Crowley, Jr., Charlotte, N.C., assignor to Southern Suction and Equipment Company, Charlotte, N.C., a corporation of North Carolina Filed Oct. 21, 1968, Ser. No. 768,991 Int. Cl. D01g 15/82 US. Cl. 19-107 2 Claims ABSTRACT OF THE DISCLOSURE This invention relates to a card cleaner plenum having a hinged portion defining a hood carrying an end wall defining a suction orifice such that by raising the hinged portion the interior of the plenum may be cleaned.
It has been found that suction plenums positioned on the licker-in or doifer cylinders are advantageous for cleaning cards. Orifices in the plenums have been positioned to exert suction at various points on the card where foreign material, such as lint is discharged or collects during carding, such as adjacent the feed roll, adjacent the juncture of the main and doffer cylinders, and adjacent the Web delivery. When chokes and the like, collect in such plenums such must be cleaned out, and it is difficult to gain access to the plenums through the restricted orifices normally provided.
Accordingly, it is an important object of this invention to provide a carding machine plenum, the interior of which is accesible for cleaning.
Another important object of the invention is to provide a plenum having a suction orifice adjacent the juncture of the main and doifer cylinders with accessibility to the interior for removal of chokes and the like.
The construction designed to carry out the invention will be hereinafter described, together with other features thereof.
The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawing forming a part thereof, wherein an example of the invention is shown and where- FIG. 1 is a schematic sectional side elevation, with parts omitted, illustrating a carding machine equipped with a cleaner plenum constructed in accordance with the present invention, and
FIG. 2 is a perspective view further illustrating such cleaner plenum.
The drawing illustrates a cleaning device for a textile card having a licker-in cylinder and a doffer cylinder including a plenum extending along and across a said cylinder. The plenum has spaced side walls joined at the top by an upper wall and is substantially closed at a bottom portion. A source of suction communicates with the plenum. A hinged hood portion A of said upper wall is connected to a fixed portion B of said upper wall, fixed with respect to the card. A hinge C connects the hinged portion with the fixed portion. The fixed portion has an open end adjacent the hinged connection between the side walls. An end wall D is carried by the hinged hood portion A adjacent the hinged connection opposite the open end. The end wall has an open portion therein defining an elongated orifice E through which suction is exerted for collecting foreign matter including lint under said hinged portion..Thus, the hinged hood may be raised so as to pivot about the hinged connection permitting access to the plenum through the open end for removing excess foreign matter from the plenum. The plenum is preferably of the type mounted on the dolfer cylinder as illustrated, and the hood A extends adjacent the web delivery. The plenum defines a second orifice adjacent the juncture of the doffer cylinder and the main cylinder.
A carding machine is illustrated in FIG. 1, which has a frame 10, a main cylinder 11, and a dotfer cylinder 12. The card is provided with flats 13 and the usual brush 14 for cleaning the flats. The main cylinder is provided with the usual front top plate 15, door 16, and bottom plate 17. The bonnet has been removed from the bonnet assembly 18 in order to accommodate the suction plenum.
While the plenum of the present invention is illustrated as being mounted on the dotfer cylinder, it is to be understood that such a plenum could be mounted elsewhere, such as on the licker-in cylinder with the hinged portion A extending adjacent the feed roll (not shown). The plenum has spaced side walls 19 and 20 joined at the top by an upper wall 21. A bottom member 22 provides a closed bottom portion. A suitable source of suction 23, illustrated schematically in FIG. 1, communicates with the plenum through an opening 24 in the side wall 20. The hood portion A of the upper wall is an extension of the upper wall 21 separate therefrom, but secured to a fixed portion B of said upper wall which is fixed with respect to the card. A hinge C connects the hinged portion A with the fixed portion B.
The plenum bottom 22 has flanges 22a and 22b which are secured to the bonnet assembly 18 as by bolts 25 which extend through openings 26 in the flanges 22a and 22b. The hood portion A has extensions 19a and 20a of the side walls 19 and 20, respectively, depending therefrom. Side walls 19 and 20- have upwardly extending triangular end portions 1% and 2011, respectively, which are joined by an end wall 26 which conforms to the curvature of and is adjacent the main cylinder 11. A tray 27, such as that illustrated in US. Letters Patent No. 3,387, 337, issued June 11, 1968 is thus formed. The tray 27 has an upturned portion 27a extending inwardly of the plenum for preventing objects falling between the card clothing of the main and doffer cylinder. A suction orifice 28 is formed for drawing lint and the like, in the area of transfer web between the main cylinder and the dotfer cylinder. Suction is exerted through the orifice 28 through the area 29 beneath the extension 27 and an orifice 30 is formed above the extension of cleaning the top wall B of the plenum.
It will be observed that the fixed portion of the plenum has an open end, as illustrated at 31 in FIG. 2, adjacent the hinged connection between the side walls. An end wall D is carried by the hood portion adjacent the hinged connection opposite the open end. The end wall D has an open portion therein defining an elongated orifice E through which suction is exerted for collecting foreign matter, including lint from under the hinged portion. The elongated orifice E may -be formed as illustrated, by a plurality of spaced slots 32 and by terminating the wall D as at 33 short of the base 22 providing an opening 34 between the marginal portions 35 and 36, which together with the upper marginal portion 37 define the open end 31.
FIG. 2 shows the hood A in raised or open position permitting access to the plenum through the open end 31. The hood A is also shown in lowered position in broken lines as it would assume during the carding operation.
The suction orifice E may, if desired, take the form of either the spaced slots 32 or the opening defined below the lower edge 33 of the wall D. The hinged hood portion A extends adjacent the web delivery 38 and the crush rolls 39. The web delivery is illustrated as including the calender rolls 38 and the crush rolls 39 through which the web passes prior to sliver formation at the calender rolls.
While a preferred embodiment of the invention has been described using specific terms, such description is for illustrative purposes only, and it is to be understood that changes and variations may be made without departing from the spirit or scope of the following claims.
What is claimed is:
1. A cleaning device for a textile card having a main cylinder, a licker-in cylinder and a dolfer cylinder including, a plenum extending along and across one of said cylinders, said plenum having spaced side walls joined at the top by an upper wall and substantially closed by a bottom wall and defining at least one open end therebetween, means fixedly mounting said plenum with respect to said card, a source of suction communicating with said plenum, a hood extending from said top wall and terminating a substantial distance therefrom, means pivotally mounting said hood with respect to said top wall, and an end wall carried by said hood adjacent said pivotally mounting means and being adjacent said one open end, said end wall having at least one opening therein through which suction is exerted for collecting foreign matter including lint under said hood, whereby said hood may be raised so as to pivot said end wall about said hinged connection permitting access to said plenum through said open end for removing excess foreign matter therefrom.
2. The structure set forth in claim 1, wherein said plenum is mounted on the doffer cylinder, and said hinged portion extends adjacent the web delivery, said plenum defining a second on'fice adjacent a juncture of the dolfer cylinder and the main cylinder.
