[57] ABSTRACT 7 Claims, 4 Drawing Figures MEANS FOR HIGH SPEED TRIMMING OF SOAP EXTRUSIONS BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to an apparatus for processing soap. More particularly, the invention relates to a highspeed wire trimmer assembly for high-speed trimming of soap extrusions, especially those of striated bar soap to obtain an improved surface finish on fresh cut extru- SlOnS.
2. Description of the Prior Art In applicant's previous patent, US. Pat. No. 3,541,652, issued Nov. 24, 1970 for Soap and Detergent Plodder, there is disclosed a soap plodder of the type on which the wire trimming assembly according to the present invention is adapted to be employed.
The plodding of soap is a well known manufacturing process and generally includes subjecting soap to a series of extrusion or plastication operations. Soap is fed to a continuous screw or worm revolving within a closed cylinder where it undergoes levigation and is then forced through a screen which converts the mass of soap into filaments or fine ribbons. Filaments of soap drop by gravity into a vacuum chamber enclosing a second rotating screw or worm serving to compress and compact the mass of soap and force it through a nozzle or orifice as a continuous bar.
Attempts have been made in the past to provide for attaching wire trimming means directly to the soap plodder housing such as is disclosed in the Austrian Patent No. 95,947. However, when soap is directly extruded from the housing against the wire trimming means, not only is a large amount of the soap mass cut off and either wasted or subjected to additional treatment, but it has been found that high-speed finishing of bar extrusions is not possible.
SUMMARY OF THE INVENTION The present invention overcomes the disadvantages of the prior wire cutting devices by providing for a wire trimmer assembly wherein a nozzle plate is detachably held inwardly of a wire cutting head for preliminarily shaping the bar extrustions so that very little soap is cut off all-owing for high-speed trimming and for allowing careful adjustment of each wire to provide for onstream sizing of the shaped extrusions into exact width and thickness to attain a finished bar having a polished surface requiring only a cutting step to provide a completed cake of soap.
The concept of this invention features the use of a nozzle plate holder having bayonet locking means for quickly detachably securing the assembly to the plodder housing. The wire cutting head is detachably secured to the nozzle plate holder with a nozzle plate for preliminarily shaping the soap mass positioned inwardly of the wire cutting head. Means are provided for electrifying the wires to provide heat to speed trimming.
Still further objects and features of this invention reside in the provision of a wire trimmer assembly that is simple in construction, compact so as to permit for highspeed operation. and which serves to trim and tinish bar extrusions in a high-speed manner.
These, together with the various ancillary objects and features of the present invention, which will become apparent as the following description proceeds, are attained by this means for high-speed trimming of soap extrusion preferred embodiments of which are illustrated in the accompanying drawing, by way of example only, wherein:
BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a longitudinal sectional view through a portion of a plodder housing illustrating an embodiment of the present invention;
FIG. 2 is an exploded perspective view of the various parts of the wire trimmer assembly;
FIG. 3 is a longitudinal sectional view, similar to FIG. 1, illustrating a modified arrangement of parts; and,
FIG. 4 is an exploded perspective view of the wire trimmer assembly shown in FIG. 3.
DESCRIPTION OF THE PREFERRED EMBODIMENTS With continuing reference to the accompanying drawing, wherein like reference numerals designate similar parts throughout the various views, reference numeral 20 is used to generally designate a plodder housing in which a mass of soap is levigated and then extruded. The housing 20 terminates in an outlet 22 which is counterbored at 24.
A nozzle plate holder 26 is provided with L-shaped bayonet-type slots 28 therein for engagement by pins 30 carried by mounting bars 32 and 34 on the housing 20. Handle means 36 may be provided for conveniently manipulating the nozzle plate holder 26 and the nozzle plate holder 26 is provided with a bore 38 therethrough. The nozzle plate holder 26 includes a peripheral flange 40 which extends inwardly of the front surface 42 thereof.
A nozzle plate 44 is provided which includes a barrel portion 46 which fits within the bore 38 and a flange portion 48 which lies flush against the outer face 42 of the nozzle plate holder 26, with the flange portion 44 being of greater diameter than the bore 38. The barrel portion 46 and the flange 48 have an inner configuration forming a die 50 which may be preferably rectangular or of any other suitable configuration for preforming and closely shaping the mass of soap being extruded.
A wire cutting head 52 is provided and includes a base plate 54 threaded as at 58 for mounting on the outside face 42 of the nozzle plate holder 26 which has threaded holes 60 for receiving threaded members 62 or fasteners. The wire cutting head has an inside counterbore 64 for receiving the flange 48 of the nozzle plate 44. On the outer face of the wire cutting head 52 is mounted four pairs 66 of slide attachments for rigid loop and hook mounting with micro adjustment of four individual cutting wires 68, which are preferably arranged two vertically and two horizontally. The individual micro adjustment of each wire 68 provides onstream sizing tothe final size of width and thickness of the finished bar and provides for a smooth high-speed cut on the extrusion. High tensile strength wire is used in a wire gauge range of 0.010 inches to 0.015 inches. The mass of soap has a moisture range of from eight to ten percent.
Because the nozzle plate is received in the bore 38 and in the counterbore 64, the entire wire trimmer assembly is very compact and easily manipulated and the speed of extrusion and cutting is increased.
An alternative arrangement is shown in F lGS. 3 and 4 wherein a nozzle plate 70 having a barrel 72 and a flange 74 is provided. The flange 74 is seated in the counterbore 24 of the housing with the barrel extending into the bore 38 of the nozzle plate holder 26. In this form of the invention the wire cutting head 52 is not provided with the counterbore 64.
In either form of the invention, the finished bars are achieved by cutting the finished extrusion transversely to form finished bars.
The slide attachment 66 may be made of electrically and thermally insulative material and connected thereto are the respective pairs of wires 68. Electrical conductors 69 are connected to the terminals of a suitable source of electrical power so that the pairs of wires 68 are spaced from each other and are electrically charged. Heating the wires will serve to enable the wires to cut the soap faster and better smooth, and glaze finish the extrusion.
A latitude of modification, substitution and change is intended in the foregoing disclosure, and in some instances some features of the invention may be employed without a corresponding use of other features.
