Definitions

  • Conventional soap presses for molding and impressing soap cakes have a magazine hopper for receiving a supply of cake blanks, and a feeding device for passing the blanks from the magazine toward the dies.
  • the hopper When charged by hand, the hopper requires continuous attention.
  • a conveyor is provided for automatically charging the hopper the blanks must reach the hopper in a close succession and the hopper must be kept well filled to prevent stoppage of the press due to blanks dropping or capsizing in the hopper.
  • the feeding device as a rule, has a plunger which ejects the blanks from the bottom of the hopper and pushes each blank against the pre ceding ones horizontally toward and beyond the die.
  • There are also feeding devices whose plunger mechanism comprises two pincer arms which not only eject the blanks from the hopper but, by means of the pincer arms, also remove the pressed cakes from the die box.
  • I provide a soap press with a horizontal belt conveyor for supplying the soap blanks and with an automatic device, placed across the supply conveyor belt, which when contacted by a travelling cake blank, cause an electromagnet to release a power-driven plunger to laterally divert the blank from the belt toward the die portion of the machine in proper phase relation to the pressing operation.
  • the two plates approach each other to catch a blank diverted from the conveyor belt by the action of the plunger; then the two plates are raised, holding the blank between each other, and are moved forward a given distance to carry the blank along. Thereafter the plates are lowered and move apart from each other, thus depositing the blank on a work table. Finally, the plates return to their initial position. This cycle covers the interval between two strokes of the machine. After a number of cycles, the blank is deposited on the bottom die. The pressing of the blank takes place during the period of time in which the plates travel back to their initial position. During a subsequent cycle the printed blank is taken up again by the plates, raised and advanced another step and so on until the blank is deposited on a take-off conveyor.
  • my invention reside in a device for centering each blank while it is being introduced into the die box, and an automatic device for arresting the machine whenever its operating members are at the starting point of the above-described cycle.
  • I provide an automatic device which, when the pressing operation is interrupted, permits the blanks to travel on the conveyor beyond the above-mentioned plun er releasing device until they reach the end of the conveyor where they may be collected to be fed again to the same or to another machine.
  • Fig. 1 is a schematic top view of the machine
  • Fig. 2 is a longitudinal section along the line 11-11 of Fig. 1;
  • Fig. 3 is a cross section along the line IIIIlI of Fig. 1;
  • Fig. 4 is a schematic perspective view of a pertaining feeding plunger controlled by an automatic electric device
  • Fig. 5 shows a detail relating to the extraction of blanks from the die box
  • Fig. 6 is a diagram of the automatic electromagnetic arrangement for arresting the machine
  • Fig. 7 is a diagram showing the electric device that permits the continuous passage of soap cakes on the supply conveyor when the machine is inactive.
  • the illustrated soap press is provided with a horizontal belt conveyor l (Figs. 1, 4) for supplying the blanks to be pressed to the die portion of the machine. If the conveyor serves several l9 and I9 (Fig. 3).
  • a movable interceptor blade 2 (Fig. 4) is placed across the conveyor belt at a given height above it. Any soap blank placed lengthwise onto the belt, travels with the belt in the direction of the arrows A
  • Hinged to lever II is a horizontally reciprocable plunger
  • the circuit of electromagnet 9 extends from contact 8 through another fixed contact l3 which, at every turn of the machine shaft l4 come into contact with a revolving contact member
  • the jaws l6 and l6 are rigidly but adjustably secured to respective guide plates 3 and 3 (Figs. 2, 3, 4).
  • One of the jaws, namely the jaw i6, is provided with a number of small spring-cushioned strips I! designed to follow small variations in the size of the soap blanks and to more firmly hold the blanks.
  • the guide plates 3 and 3' are mounted and driven to perform three movements.
  • One of these movements is reciprocal and transverse to the blank feed direction, both plates moving toward and away from each other in the directions of the arrows A3 and A4 (Fig. 1).
  • This movement is imparted to plates 3 and 3' by respective levers l8 and I8 from respective cylindric cams
  • the second movement is a lifting and lowering movement as indicated by arrows A4 and is imparted to plates 3 and 3' by respective levers 2!] and 20 from cam disc 2
  • the third movement is forward and reverse, as indicated by arrows A5,
  • are all operated from the drive of the press mechanism so that the three reciprocal plate movements occur in a fixed sequence and in a cycle coinciding with the operating cycle of the press.
  • the operating movement of the top and bottom dies 24 and 23 takes place in the interval of time during which the plates 3 and 3 perform the return stroke of their third movement.
  • a device for centering the blank enters into action.
  • This device has two paddle-shaped arms 4
  • are hinged on an axle 42, along which they can slide and are supported by fulcrum pieces 43 and 43' rigidly secured to two reciprocating gear racks 44 and- 44' meshing with a pinion roll 45.
  • Rack 44 is driven by a lever 46 from a cam disc 41, that impart to the rack an alternating horizontal movement (arrows At) which causes arm 4
  • Pinion 45 causes rack 44 to simultaneously move the arm 4
  • the approaching movement takes place when arms 4
  • the lowering and raising motion is imparted to arms 4
  • the machine is controlled by a starting pushbutton 21 and a stop push-button 28 (Figs. 1, 6).
  • the stop button 28 When the stop button 28 is depressed, the machine does not stop immediately but continues running until bottom and top dies 23 and 24 are at their upper dead centers and the plunger 12 is locked in its rest position.
  • This is achieved by a relay circuit shown in Fig. 6.
  • the normally closed push button 28 lies in the coil circuit of a relay 2!] in parallel relation to a normally closed switch contact 30 controlled by a cam 53 on the machine shaft 14.
  • the coil circuit of relay 29 continues to receive current through the by-pass contact 3! ⁇ until contact 30, being driven by cam 53 in proper phase relation to the operative stroke, opens the circuit and causes the machine to stop at the desired position above mentioned.
  • the machine is provided with a brake 3
  • the supply conveyor may be driven by a separate motor independent of the drive motor of the press.
  • the conveyor belt I keeps on running.
  • an automatic system is provided for lifting the blade 2 out of the path of the blanks travelling on the conveyor.
  • This system illustrated in Fig. 7, has an electric circuit in which an electromagnet 35 and two contact devices are put in series. One of these devices is a normally open push-button contact 36. The other contact device has stationary contacts 39 and a normally closed movable contact 40 of relay 29. Operation of the electromagnet 35 is, therefore, dependent upon non-operation of the soap press. In this condition, when button 36 is depressed, the electromagnet 35 attracts the blade 2 and lifts it sufficiently to permit the soap blanks to travel freely on the independently driven conveyor I.
  • a machine according to the invention eliminates the disadvantages of the conventional machines since the supply of blanks does not require special attention, and the pressed cakes, whatever the engraving may be, is always taken off the bottom die by a raising movement and independently of the operation of the feeding plunger.
  • the press movements are independent of the supply conveyor movements so that, if desired, the blanks charged onto the supply conveyor may be diverted from their way to the pressing stage.
  • a movable interceptor member disposed above said conveyor in the path of the blanks, control means connecting said member with said stop means for controlling said stop means in response to movement of said member to release said plunger in dependence upon a blank abutting against said member, a feeding device disposed on said worktable surface and having two guide parts extending parallel to the stroke direction of said plunger and being spaced from each other, at least one of said two plates being movable toward and away from the other plate to periodically hold between said two guide plates the soap blanks diverted from said conveyor, and said two plates being periodically movable upwardly and downwardly as well as forwardly and reversely to incrementally advance and deposit the blanks on said surface, and drive means connected with said die-press portion for imparting movements to said two plates in a fixed phase relation to the pressing operation.
  • a machine comprising two jaws adjustably secured to said respective two plates at the inner sides thereof, one of said jaws having a number of spring-biased strips projecting toward the path of the blanks and engageable with the blanks, said strips being center spaced from each other along the blank path a distance equal to the forward advance movement of said two plates of an individual cycle of plate movements.
  • a machine comprising a pressure lever having a vertically reciprocable portion engageable with the blanks and disposed above said surface between said plates, said lever being synchronized with said plates to descend into engagement with a blank being deposited by said plates onto said surface.
  • said feeding device extending from said conveyor to beyond said die-press portion and being engageable with the die-pressed cakes for removing them from said die-press portion, and a take-01f conveyor adjoining said device to receive said cakes.
  • said feeding device having projecting elements disposed at the die location and engageable with the blanks at said location to laterally impress the blanks.
  • a machine comprising a centering device having two arms pivoted for mutually opposing angular movement and extending transversely of said plates at both respective sides of the die location, said arms being engageable with a blank at said die location for centering the blank due to said angular movement, and said arms being capable of joint reciprocal displacement in the vertical direction for placing the blank into pressing position, and drive means connected'with said arms for imparting thereto said angular movement and said vertical displacement in a fixed phase relation to said pressing operation.
  • a machine for pressing and molding soap cakes comprising a die-press portion having a, substantially horizontal work-table surface, a horizontal belt conveyor extending beside said surface for supplying thereto the cake blanks to be pressed, a feed plunger having an inactive position and being reciprocable from said position across said conveyor and toward said surface for diverting the blanks from said conveyor onto said surface, stop means engageable with said plunger to arrest it in said inactive position, a movable interceptor member disposed above said conveyor in the path of the blanks, control means connecting said member with said stop means for controlling said stop means in response to movement of said member to release said plunger in dependence upon a.
