Definitions

  • This invention relates to mechanisms and means for producing hard shell capsules for pharmaceuticals and the like and is more particularly an improvement in capsule production apparatus and means described in the patent to Arthur Colton; U.S. 1,787,777 dated Jan. 6,
  • the Colton patent apparatus is described for forming the cap and body parts of hard shell gelatin capsules, for assembling these cap and body parts as empty joined capsules, and for discharging the assembled capsule from the apparatus.
  • the capsule bodies and caps are separately formed from a gelatinous film or coating which is applied to dip-molding pins supported in a row on a bar, hardened on the pins and then removed. In the process after the capsule bodies and caps are removed from the pins, the bodies and caps are trimmed to accurate length dimension and then assembled together temporarily prior to filling, printing, etc.
  • FIGURE 1 is a side view of a holder bar assembly with its associated array of rejection fingers according to the invention
  • FIGURE 2 is a top view of component parts of the assembly shown in FIGURE 1;
  • FIGURES 3 and 4 are perspective views of a portion of the guide block assembly of a capsule production machine showing in detail a portion of the associated bar assembly of FIGURE 1;
  • FIGURES 5 and 6 are perspective views, fragmented in part, illustrating certain phasing elements of a preferred embodiment of the invention including cam pusher means and associated guide means;
  • FIGURE 7a is a side view of a rejection finger according to the invention.
  • FIGURE 7b is a front elevation of the rejection finger of FIGURE 7a.
  • FIGURE 8 is a sectional view of the rejection finger taken at line 8--8 of FIGURE 7a.
  • a preferred form of the rejection assembly 10 of FIGURE 1 includes the holder bar 11 on which is mounted a row of rejection fingers or finger means 20.
  • the holder bar is supported by cam bar 30 and is removably attached to the cam bar by the screws 12 fitted into the mounting slots 13.
  • the holder bar 11 contains as shown 30 colinear vertical channels 14. Each channel 14 is adapted to receive a rejection finger 20.
  • the position and orientation of each finger are determined by set screw means 15 or the like cooperating with cutaway flat 22.
  • the finger 20, shown in detail in FIGURES 7a, 7b and 8, includes a generally cylindrical base 21 and the mentioned fiat 22.
  • an upstanding shank portion 23 In line with the central axis of the finger is an upstanding shank portion 23 which includes an outwardly flaring boss 24 in a line generally perpendicular to the fiat 22.
  • the shank 23 also includes the spike portion 25 extending upwardly from the boss 24.
  • the spike advantageously serves to prevent random seating of capsule parts on shank 23.
  • the base 21 of the rejection finger 20 is inserted into the vertical channel 14 to the point where fiat 22 coincides with the set screw 15. At this position the set screw 15 is locked into the flat to insure that the finger 20 and its boss 24 are in correct alignment.
  • the finger 20 can according to the invention have any of various configurations and is not limited to the preferred embodiment described.
  • any configuration is suitable which includes a capsule contacting surface moving in and out of the path of a capsule in a manner equivalent to the boss 24.
  • one such equivalent is one having the shank portion 23 but, by way of substitution, having a receiving channel (instead of boss 24) adapted to circumscribe the over-length portion of an oncoming capsule.
  • the cam bar 30 adjustably supports the holder bar 11 and includes with the holder bar a slotted recess 31 to receive cam plate 32.
  • the cam plate is removably mounted on the cam bar by screw means 33 or similar means.
  • the cam bar 30 also includes mounting slots 34 to permit adjustable attachment to the pedestal (not shown) of a standard Colton capsule production machine or similar machine by means of anchoring screws 35:: and 35b. Adjacent to screw 35a is a tubular recess 36 adapted to receive tension control spring 37.
  • the rejection assembly 10 in closed position is illustrated as at FIGURE 3 where the rejection finger stands immediately in front of the guide block means 40 where it intersects the path of travel of the capsule part of the guide block means and blocks entry to guide channel 41.
  • the position of the rejection assembly 10 in the closed position referred to is that represented in FIGURES 1 and 2 Where the control spring 37 is in an uncompressed condition.
  • FIGURE 4 shows the rejection finger 20 in the open position. In the latter position the rejection finger has been displaced from the position shown in FIGURE 3 by reciprocation of the holder bar 11 from right to left. Reciprocation of the holder bar is accomplished by the cam pusher mechanism shown in FIGURES 5 and 6. This mechanism includes cam pusher 60 and cam pusher bracket 61 and strap 62.
  • the cam elements preferably are made of tool steel whereas cold rolled steel is suitable for other elements of this and other mechanisms herein de scribed.
  • the cam pusher has camming surfaces 63 for slanting contact (preferably at a 45 angle) with corresponding cam portion 32a of cam plate 32.
  • the opposite end of the cam pusher includes slot 64 for adjustable mounting of the cam pusher 60 with cam pusher bracket 61 by set screw means 65.
  • the cam pusher bracket 61 in turn is attached by screw means 66 to the collet mounting (shown in the Colton patent) so that the cam pusher assembly moves in phase with the collet assembly.
  • the cam pusher mechanism also includes the catch rod 70 shown in FIGURES 5 and 6.
  • the catch rod is removably fixed to the ejector rod mounting (shown in the Colton patent) for movement in phase with the ejector rod assembly.
  • the catch rod is slidably mounted on the cam pusher 60 as shown to accommodate relative shifting motion to and from the positions shown in FIG- URES 5 and 6.
  • the capsule part is formed by dipping the mold pin in gelatin and drying the shell formed.
  • the dried shell is then processed by the so-called automatic unit which strips the shell from the pin and trims and joins the capsule parts.
  • the present invention is applicable, as indicated, to either capsule bodies or capsule caps. In the nature of the inspection problem, however, the invention is particularly useful for processing capsule bodies. It will be realized in this connection that the apparatus and operation on the body and cap sides of the machine are in principle equivalent.
  • the empty capsule body part 50 having been stripped from the capsule pin, is supported by the collet means 51, trimmed, elevated and advanced toward the guide block 40 where it assumes the position shown in FIGURE 7a.
  • the advancing motion is in phase with the inward motion of the collet and collet mounting (not shown) which mounting serves as a guiding and driving support for the apparatus shown in FIG- URES 5 and 6.
  • the latter mounting which is integral with the collet, moves inward with respect to the cam plate 32 so that, as the collet means 51 advances with its capsule part 50, the camming surface 63 contacts the cam plate 32 and its camming surface 32a thereby causing the rejection assembly 10 with its holder bar 11 and cam bar 30 to move the rejection finger 20 from right to left from the closed position of FIGURE 3 to the open position of FIGURE 4, as indicated by the double arrows.
  • the invention includes catch rod 70 which in phase with the inward advance of the ejector rod is caused to corespondingly advance to the position shown in FIGURE 6 where it catches the trailing edge 32b of the cam plate 32 and holds the control spring 37 under compression and prevents the premature return of the rejection assembly 10 from the open position of FIGURE 4 to the closed position of FIGURE 3.
  • the collet means 51 when the collet means 51 carries the capsule part 50 to the rejection finger 20 in closed position and when the capsule part 50 exceeds the standard length as represented by the extension shown by the dotted line, the boss portion 24 of the rejection finger lies within the open end of the capsule part 50 and is surrounded by the encircling capsule wall.
  • the adjustment of the cooperating parts of the mechanism can be precisely controlled so that the standard capsule parts, i.e., parts having the standard length being produced, will just clear the work surface of the rejection finger during the course of travel of the capsule part in the described area to the guide block 40.
  • the standard capsule parts therefore are allowed to pass for final assembly.
  • capsule parts exceeding standard length by even the slightest dimension are caught by the rejection finger and damaged to the extent that they fail to join in normal fashion, are automatically rejected or are singled out as defective, etc.
  • Apparatus of the kind described for capsule production operable in a continuous predetermined cycle for selectively passing standard capsule parts and for rejecting long capsule parts, comprising:
  • collet means for supporting and imparting motion to individual capsule parts in succession and in timed relation along a continuous path from a work station to the guide block means
  • finger means between the work station and guide block means operative in a first position to intersect the path of travel of oncoming capsule parts and in a second position to retract out of the path, and means for advancing the finger means to and from the first and second positions in timed relation to the travel of each capsule part, the advancing means being operative to cause the finger means to assume the first position and intersect the path of travel for a period at least just prior to the time corresponding to the arrival of the leading edge of each standard capsule part and to cause the finger means to retract thereafter from the first position for a period corresponding at least to the time required for passage of a standard capsule part, the finger means for retraction from the first position being adapted to move clear of. standard capsule parts but to contact and destroy long capsule parts whereby the long capsule parts are rejected.
  • Apparatus according to claim 1 adapted for handling capsule body parts.
  • Apparatus of the kind described for capsule production operable in a continuous predetermined cycle for selectively passing standard capsule body parts and for rejecting long capsule body parts, comprising:
  • guide block means for receiving and joining matching open-ended capsule parts
  • collet means for supporting and imparting motion to individual capsule body parts in succession and in timed relation along a continuous path from a work station to the guide block means, the collet means being adapted to bring the parts with open end first to the guide block means, finger means between the work station and guide block means operative in a first position to intersect the path of travel of oncoming capsule body parts and in a second position to retract out of the path, and
  • the advancing means being operative to cause the finger means to assume the first position and intersect the path of travel for a period at least just prior to the time corresponding to the arrival of the leading edge of each standard capsule body part and to cause the finger means to retract thereafter from the first position for a period corresponding at least to the time required for passage of a standard capsule body part, the finger means for retraction from the first position being adapted to move clear of standard capsule body parts but to contact and destroy long capsule body parts whereby the long capsule body parts are rejected.
