Definitions

  • the invention relates to an automatic molding press which is adapted for molding finished pieces from an extruded continuous strand of plastic material such as a solid soap, a paraffin wax, and the like, with means for conveying the extruded strand along a horizontal path, in correspondence of which molding means are arranged, which are adapted for acting in a horizontal direction upon the strand, transversely thereto, and comprise a box-shaped matrix arranged on one side of the strand and provided with a movable molding bottom, and a mold which is arranged on the opposite side of the strand and is moved with a reciprocating motion for being cyclically engaged in the matrix.
  • plastic material such as a solid soap, a paraffin wax, and the like
  • An automatic molding press of this kind is known from the document FR-A 1 220 937.
  • this known molding press on a drum rotating about a horizontal shaft arranged transversely to the soap strand, there is provided a plurality of molding pairs consisting each of a mold and a corresponding matrix, and which are angularly spaced apart from each other in such a manner that by the rotation of the drum, these molding pairs are brought the one after the other in correspondence of the soap strand, where the mold is temporaneously driven into the matrix.
  • the drum is rotatably driven by a motor, through a gear drive, and the mold and the movable bottom of the matrix are driven, that is, are axially displaced, by means of stationary cams, and possibly by means of return springs.
  • the means for conveying the extruded strand along the horizontal path are not fully described and shown in this document FR-A 1 220 937.
  • a machine for cutting soap, in which a strand is conveyed along a horizontal path by means of a pair of opposed friction rollers.
  • a hidraulic molding press is known for molding finished pieces from an extruded continuous strand, in which the strand is fed from above by gravity in an inclined direction, between a mold and a corresponding matrix, so that no means are provided for conveying the strand along a horizontal path, while the mold is operated by a hydraulic cylinder.
  • a machine is known for making tablets by compressing a powdered material between a punch and a matrix having a movable bottom. The punch and the matrix bottom are operated by means of swingable levers by a common cam.
  • the object of the invention is to improve a molding press of the type as described at the beginning, and known from the document FR-A 1 220 937, so that a simple construction, as well as a high productivity and a reliable operation, are attained.
  • numeral 1 denotes as a whole the fixed supporting structure of an automatic molding press according to the invention, which is for molding finished pieces P directly from a strand B of soap and any similar products, continuously extruded from an extruder (not shown) of a known type.
  • the said structure 1 carries means for entraining the strand B, which preferably comprise a pair of horizontal parallel ribbons 2 facingly arranged at a short distance from each other, with the strand B being engaged therebetween.
  • each one of the said ribbons 2 consists of an inwardly toothed belt stretched between two guide sprockets 102, of which one is a motor-driven sprocket.
  • the strand B is advanced stepwise, in such a manner that its end portion will be brought exactly in correspondence with molding means provided at the sides thereof, which are adapted for cutting and molding the pieces P.
  • the said molding means comprise a mold 3 which is imparted a reciprocating motion, and cooperates with an oppositely arranged, box-shaped stationary matrix 4.
  • the mold 3 is carried by a slide 5 slidably mounted between rollers 6 and connected to a rockable driving arm 7, which by means of a connecting rod 8 is connected to a disk crank 9, which through reduction gearings 11, 12 is driven in rotation by the motor 10.
  • the rockable arm 7 is fulcrumed at 107 about a compensating lever 13, which is in turn pivoted at 113 to the supporting structure of the molding press.
  • the box-shaped matrix 4 which is also called box, comprises an elastically movable molding bottom 104. More particularly, the bottom 104 is fitted to one end of a slidable stem 204 which is co-axially engaged by a cylindrical spiral thrust spring 304 that when in rest condition, positions the said bottom in correspondence of the opening of matrix 4.
  • the said spring 304 bears against two spring-supporting elements 404 and 504, of which the first is screwed to the free end of stem. 204 and is designed for abutting, under the bias of spring 304, against a fixed abutment block 604, while the second is applied to the end of a bolt 704 screwed in a fixed support 804.
  • Such an assembly of these components permits both to alter the position of the molding bottom 104 at the opening of matrix 4, and to adjust the thrust load of spring 304.
  • the mold 3 is moved forward against the opposite matrix 4, so that a portion of strand B located therebetween is inserted into the matrix, and a commensurate backward movement of the bottom 104 under the thrust of the piece molded, is caused to occur. Therefore, owing to the concurrent action of the matrix and the mold, every single piece is cut and is simultaneously molded by the mold, in cooperation with the opposed bottom 104.
  • the mold 3 is drawn away from the matrix 4, and owing to the thrust of spring 304, the bottom 104 of the matrix can expel therefrom the finished piece P, which is taken up by an underlying horizontal ribbon 14 with its active upper stretch running either continuously or stepwise in the same direction as the strand B.
  • the separation from the matrix 4 of the already expelled piece P is assured by a pushing member 15 which in rest position is located just over the opening of matrix 4.
  • the said pushing member 15 is carried by two lateral arms 115 which are pivotally connected at 215, and one of them is a square-shaped arm.
  • the square-shaped arm 115 comprises a washer element 315 which is engaged between two antagonistic means consisting of a cylindrical spiral compression spring 415 and a rod 16 fitted on pivot 17 so as to be rockable thereabout.
  • the rocking movement of rod 16 is controlled by a cam 18 keyed onto the same shaft 19 for the rotation of the already mentioned disk crank 9, the cam 18 being into engagement with a roller 116 carried by the rod 16. It is obvious that the alternate prevalence of the spring 415 and of the rod 16 over their relative antagonistic means will respectively bring about the activation and the de-activation of the pushing member 15.
  • the sprockets 102 driving the facingly arranged ribbons 2 for moving forward the strand B carry on the shafts 202 for their rotation respective freewheel devices 302 which are engaged in counter-rotation by a chain length 20 which is alternately pulled in one direction by a driving lever 21 (see figure 2) and in the opposite direction by a return spring 22.
  • the said driving lever 21 that causes the active travel of chain 20, i.e., the travel by which the freewheels 302 come to be coupled with the respective shafts 202 for the rotation of the driving rollers 102, is fulcrumed at 121 and is swung by a lever 23 connecting it to a second crank disk 24 which is also keyed onto the shaft 19.
  • the said lever 23 is pivotally connected to a rod 25 which is fulcrumed at 125.
  • the position of the fulcrum 125 of rod 25 is adjustable by means of the threaded stem 26, in order to render it possible to alter the arc over which the lever 21 swings, and thus the extent of the forward step of strand B.
  • the said device which in itself is very simple, consists of a lever 27 which is fulcrumed at 17, and through a trace 28 is connected to a lever 7. Under normal operative conditions, the said lever 27 rocks idly, but when the said anomalous conditions occur, this lever pushes the spring-supporting element 404 so as to draw the bottom 104 away from the mold 3 in the course of being engaged with the matrix 4.
  • Another safety device provides for the possibility of an elastic sliding movement of the compensating lever 13, in the instance in which in correspondence of the molding means the thickness of the strand B comes to be increased owing to any accidental cause (such as, for example, owing to a finished piece sticking to one side of the strand end).
  • the lever 13 is movably engaged in a bushing 213 pivotally connected at 113, and cooperates with a return spring 313.
  • adjusting means are provided, which conform the production rate of the molding press to the speed at which the extruded strand is advanced.
  • the said adjustment means are described and shown in a former Patent Application of the same Patentee, relating to a similar molding press, and for this reason they are not discussed here in detail.
