Definitions

  • ABSTRACT [52] US. [51] Int Cl [58] Field of Search425/269, 270, 385, 324, 324 B;
  • This invention relates to capsule making apparatus and more particularly to an improvement in means for .movement through drying kilns until the film has solidified. It has been considered essential in this operation to rotate the pin bars during elevation in order to maintain uniform distribution of the liquid film on the pins. Nevertheless, the practice often results in a nonuniform thickness in the capsule shell wall, particularly in the so-called shoulder area. It is found, for example, that the shoulder wall on the leading side of the pin in the direction of the rotation is usually thin whereas on the trailing side it is relatively thick.
  • FIG. I is an elevational view partly in section of capsule making apparatus including a dipping tank, elevator and air duct system;
  • FIG. 2 is a view of the air duct of FIG. 1;
  • FIG. 3 is a fragmented view of an air duct
  • FIGS. 4 and 5 are enlarged views of coated mold pins in the pin down and pin up positions, respectively.
  • the dipping tank which may be conventional in form includes a dipping dish 11 surrounded by a reservoir 12 containing dipping solution 13 in a constant temperature jacket 14.
  • Capsule pins mounted on bars 21 are located, as illustrated, at successive work stations of the operation: at the dipping station A, at the base or loading station B of an elevator 30, at the unloading station C (dotted outline), and at a platform which is the starting run D through a series of driers.
  • Mechanical finger means (not shown) are provided in connection with'each dipping cycle for engaging and sliding the pin bar set at A along a guide track 22 into the loading station B of the elevator.
  • the elevator has a pair of vertical racks 31 which cooperate with a like pair of pinion gears 32 and discs 33.
  • the two discs each have a groove 34 and are spaced in the loading position illustrated, with the grooves in alignment with the top surface of the guide track 22, to receive the opposite ends of each advancing pin bar for loading.
  • a flanged retainer ring 35 Surrounding the elevator disc 33 is a flanged retainer ring 35 which remains stationary with respect to the disc and thus serves to retain the pin bars within the groove as the disc rotates while moving upwardly on the rack.
  • the gear and rack combination is arranged for movement of the elevator to the upper terminal position C illustrated in dotted outline at which the elevated pin bars stand in the pin up position for transfer from the groove 34 to the platform 40.
  • an air duct or conduit is provided having an open outlet 51 located below the loading position B.
  • the air duct communicates with a suitable source (not shown) of clean air under positive pressure at room temperature or lower temperature.
  • a suitable source not shown
  • the air duct outlet 51 is sufficiently large to surround the array of pin ends 20a of bars at the loading station.
  • the end of the conduit 50 may have an outward flare 52 to favor a greater outward flow of air around the perimeter of the array of pins.
  • FIG. 2 features distribution baffles 53 and a screen tray 54 which insure uniform air flow across the opening 51 through the confined zone surrounding the pin ends 20a at the loading station.
  • the screen tray preferably fits the outlet opening closely and is removable for cleaning purposes.
  • Opening 51b serves to provide clearance for unloading the bars 21 from station C to the platform 40.
  • the pins 20 are dipped in gel solution, withdrawn, exposed to air flow and transferred to the loading station B, elevated with rotation, transferred to the drier, dried, stripped, and greased (in preparation for the next cycle).
  • the solution which may be an aqueous gelatin solution is maintained at a suitable temperature, conveniently in the range'from about ll0-l15 F.
  • the pins are dipped five bars at a time at the rate 0E0 bars per minute. The time required for dipping, loading, and elevation and transfer to the drying platform 40 is about 15 seconds. Transfer to the elevator (position A to position B) requires less than one second, following which the pin bar sets come to a dead stop.
  • air is delivered through the orifice 51 (or 51a, FIG. 3) under conditions such as to cool and stabilize the film coating on the pins, for example at room temperature or lower under controlled humidity, preferably 50 percent or lower, and at a linear flow rate of about 5 feet per second.
  • the air-flow conveniently is continuous so that the pins are exposed to the same during the transfer to position B and during the dead stop and elevation. Substantially all of the filmstabilizing effect takes place during the transfer and dead stop.
  • the elevator is activated in conventional manner and the loaded pin bar sets are rotated to the terminal position C adjacent the drier platform 40.
  • the pins While being elevated the pins are rotated (standard rotation is two and one-half times) from the pin down position tothe'pin up position illustrated in dotted outline. Following a short dwell time, the pin sets are transferred to the drier platform 40 and are then processed through the remainder of the cycle in conventional fashion.
  • FIG. 4 illustrates the deformation of the film coating 22a shown in dotted outline as the pin 20 is being rotated from the load position and elevated.
  • the film coating 22b shown in solid outline is typical of the air treated coating during the same phase of rotation.
  • the film coating at the shoulder line 20b remains substantially uniform.
  • FIG. 5 illustrates the configuration of the coating of the fully elevated pin.
  • the dotted outline 22b illustrates the coating profile as the pin first arrives at position C.
  • the solid outline 22c illustrates the profile of the finished film dried on the pin.
  • the film coating at the end 20a of the pin is relatively thick. However, with progressive drying the coating evenly redistributes itself axially upon the surface of the pin to provide a generally uniform thickness.
  • a critical measure of quality of molded capsules concerns the variation in wall thickness at the shoulder line 20b.
  • the wall thickness in a given capsule should be constant throughout the shoulder line.
  • the wall should be relatively thick at the shoulder.
  • capsule making apparatus comprising a set of capsule pin bars having elongated pins each pin having a rounded end, a dipping tank, and means for transferring the pin bars continuously in timed relation through a stepwise cycle of pin dipping in gel solution, withdrawing and inverting the pins while coated with liquid film which is subject to uneven distribution during transfer under action of gravity, and drying and stripping the coating on the pins
  • the transfer means including an elevator for lifting and rotating pin bars from a loading station and means for supplying the loading station with bars of freshly dipped pins with the rounde end of each pin lowermost
  • air conduit means having a distribution orifice located adjacent the loading station for moving cooling air upwardly against the rounded ends of the coated pins, the orifice being shaped to provide for uniform flow through a confined zone surrounding the array-of pin ends of bars at the loading station.
  • Apparatus according to claim 1 wherein the distribution orifice is located above the loading station and the air conduit means is in communication with a source of negative air pressure.
  • Apparatus according to claim 1 wherein the air conduit means is in communication with a source of air pressure adapted to generate air flow through the confined zone at a rate sufficient to stabilize the liquid film coating on coated pins located at the loading station.
