Definitions

  • This invention relates to anapparatus and a method on both sides, can readily be converted to a different dragee format, and, in spite of the small floor area it requires, provides space for palletized transport means.
  • the apparatus of the invention meets industrial requirements in regard to precision and safety, and is suitable for imprinting not only dragees but also tablets and capsules.
  • the apparatus of the invention consists essentially of, in combination, a feed hopper, a rotating cylindrical transport drum providedwith receiver apertures to receive and hold dragees, printing rolls disposed one inside and another outside of the transport drum and pressing lightly against the dragees, and a printing ink supply system tosupply the printing rolls.
  • the receiver apertures may be fitted with projections on the inner side of the cylinder wall which grip only the outer margin of the dragee being imprinted.
  • transparent guiding members are provided on both sides of the drum wall and consist preferably of Plexiglas.
  • a guiding memher is required only on the outer side; otherwise guiding members are provided on both sides of the drum to prevent the dragees from falling out of the drum.
  • a wiper brush is also located in the feed hopper on the side nearest the printing rolls to aid in introducing the dragee one at a time into the aperture; within the transport cylinder, below the printing rolls, there is provided an. ejector brush to ensure removal of the imprinted dragees.
  • the transport drum is conveniently driven by a disk mounted on a drive shaft (the disk constituting the bottom of the drum) and the printing rolls and the brush are conveniently mounted at the open side of the transport drum; furthermore, the transport cylinder and the printing rolls may be rcmovably fastened with screws to their shafts to be axially removable.
  • the apparatus of the invention also comprises an ink supply system; e.g., two ink reservoirs with 'ink level control and displaceable covers which have openings for gravure rolls and are fastened on by means of tension springs, a receiving hopper with a locking shut-off means, and an opening in the machine frame and rails provided with rollers for palletized transport means. It is desirable to combine the apparatus of the invention with a pneumatic conveyor tube leading to a container holding a supply of the material being imprinted, the whole assembly forming one compact unit.
  • FIG. 1 shows the entire apparatus in a front elevation.
  • FIG. 2 shows the entire apparatus in a top plan view.
  • FIG. 3 shows the receiving apertures in the transport cylinder.
  • FIG. 4 is an enlarged sectional view of the area 4-4 of FIG. 2 showing the mounting of the transport cylinder.
  • FIG. 5 is an enlarged vertical sectional view partly broken away of the area 5-5 of FIG. 2 showing the fastening of the rolls.
  • FIG. 6 shows the arrangement of the system for circulating the printing ink through the entire apparatus.
  • FIG. 2 is a top plan view of the entire apparatus, especially showing the arrangement of the drive and of the rolls.
  • the motor drives the shaft 14, with the disk 15 welded thereon, by means of a chain drive.
  • FIG. 6 shows the arrangement of the closed circulatory system for the printing ink 16 throughout the entire apparatus, supply reservoir, flexible-tube pump, and two ink reservoirs 17 with ink level control system and displaceable covers having openings for gravure rolls and being fastened by tension springs.
  • the dragee to be printed are delivered pneumatically through an air tube to the feed hopper l or they are placed therein by hand.
  • the receiving apertures 6 of the rotating transport cylinder 2 pick up dragees in the supply hopper. They can be covered up while the machine is running by a-displaceable grid in the supply hopper.
  • the brush 3 serves as a wiper for introducing dragees one at a time into apertures 6 in cylinder 2.
  • the Plexiglas guide 4 holds the dragees in the receiving apertures 6 on their way to the printing rolls 5. In this section of the transport cylinder the receiving apertures 6 may be inspected to see that they are filled.
  • the dragees are imprinted as they pass the printing rolls 5.
  • the receiving apertures 6 have projections or holding abutments 7 at the inside wall of the transport cylinder.
  • printing is performed only by the one printing roll while the other operates only as a counter-pressure roll.
  • plexiglas guides may also be provided inside of the transport cylinder 2 from the feed hopper to the printing rolls (FIG. 1).
  • the dragees drop out of the transport cylinder through the discharge funnel 9 into the container 12.
  • the brush roll pushes the dragees out of the apertures if necessary. It is driven through a chain drive.
  • the surface of the gravure rolls 18 are wetted with ink in the ink reservoirs. Wipers wipe the ink from the steel rolls again. Ink remains only in the gravure of the rolls whence it is transferred to the printing rolls (e.g., rubber rolls) and from these it is transferred to the dragees.
  • the ink is circulated in the closed system by a flexible-tube pump.
  • the ink reservoirs are emptied through valves into an ink supply tank in which the ink level can be inspected by means of a level indicator.
  • the printing rolls may be pivoted away from the transport cylinder a distance of about 50 mm. At the same time they are lifted a few millimeters from the steel rolls. The printing rolls are kept in rotation through a gear connection with the steel rolls.
  • the rubber and gravure rolls 5 and 18 are of cylindrical configuration and they are mounted on the drive shafts 22 and tightened in place with screws 21 contained in slotted collars 20 on the rolls (FIG. 5).
  • the rolls 5 may be displaced axially from shafts 22 and radially when the machine is being adjusted.
  • the machine is driven by the controlled-speed motor 13.
  • the motor drives the shaft with the disk welded onto it.
  • the motor also drives the steel roll through a chain drive and the steel rolls drive the printing rolls through gears.
  • the transport cylinder and the rolls run in synchronism.
  • the transport cylinder 2 which is fastened to the disk with only three screws, and/or all of the rolls may be drawn off towards the rear and replaced with others within a few minutes.
  • Theposition of the transport cylinder 2 on the disk 15 is fixed by locating pins.
  • the transport disk has apertures through which the rolls disposed within the transport cylinder may be removed in the direction of the transport disk.
  • Palletized aluminum containers may be used as the offbearing containers 12 which are used for intrafactory transportation. No great expenditure of force is required for the removal of the filled aluminum containers from the machine, since the containers run on rails 11 which may also be provided with rollers. The machine does not have to be shut off while the containers are being exchanged, since the dragees may be collected in the outfeed hopper 9 during this period by means of the shutter 10 which pivots about axis 10'.
  • This machine for the imprinting of dragees etc. may be made from common metallic materials.
  • the transport cylinder may be made either of metal or of plastic.
  • dragee as used herein is meant to refer to dragees, tablets, capsules, and the like, or other forms of pharmaceuticals or foodstuffs which are amenable to being imprinted by use of the present invention.
  • Apparatus for the imprinting of dragees which apparatus comprises, in combination, feed hopper means, a rotating cylindrical transport drum having a plurality of receiving apertures adapted to receive dragees from said hopper and to hold dragees, a pair of printing rolls parallel to the axis of said transport drum, one roll of said pair positioned on the outside of said drum and the other roll of said pair positioned on the inside thereof, said pair of rolls being adapted to lightly press against both sides of the dragees in said apertures of said transport drum, and means for supplying printing ink for said printing rolls.
