Definitions

  • the reservoir is reciprocated between printing and non-printing positions by a solenoid.
  • a U-shaped member seals off a plurality of ports connecting the reservoir with the porous printing member.
  • the reservoir moves away from the U-shaped member, permitting ink to pass through said ports to the porous printing member.
  • the U-shaped member assists in forcing the ink through the ports to said printing member prior to effectively sealing off said ports when the reservoir finally reaches the non-printing position.
  • This invention relates, to printing apparatus, and more particularly it relates to an apparatus for replenishing a supply of ink to a capillary, porous-type printing mem- -ber which is brought into contact with the material to port memberrAs the printing member is used in the machine, the supply of ink contained in the printing member itself is exhausted, and consequently the member must be removed from the machine 'to be refilled at frequent intervals.
  • an ink reservoir was operatively connected with the printing member, so as to replenish itjwith'inkas the printing member was used in its normal stamping operation. It was discovered, however, that,
  • a primary object of this invention is to provide an apparatus for replenishing a supply of ink to a capillary, porous-type printing member at a rate determined by the use thereof and to close off the supply thereto when the apparatus is moved from a printing position to a non-printing position.
  • Another object of this invention is to provide an apparatus of the above type which provides for an equal distribution of ink to the porous printing member.
  • the re-inking device of this invention may be used in a printing apparatus having a frame member and a platen.
  • the device generally comprises an ink reservoir having an ink-'replenishable, porous printing member carried thereby on the side thereof which faces the platen.
  • the reservoir mentioned above has a plurality of passages interconnecting it with the porous printing member.
  • means inside the reservoir are provided to first force a supply of ink through said passages to the printing member, and then seal off the passages to prevent further passage of ink to the printing member as long as the reservoir is held in the non-printing position.
  • FIG. 1 is a general perspective view of the invention partly in section and showin the device in the nonprinting position relative to the platen, upon which an article to be printed upon is positioned;
  • FIG. 2 is a cross-sectional view of the device of FIG. 1 showing the passages interconnecting the reservoir with the porous printing member and means for securing the reservoir to the driving solenoid;
  • FIG. 3 is a plan view of the underside of the reservoir shown in FIGS. 1 and 2 and the porous printing member secured thereto.
  • the re-inking device of this invention comprises an ink reservoir, generally designated 10, which is positioned between the frame 12 and the platen 14, as shown in FIGS. 1 and 2.
  • the reservoir 10 is composed of a liquid-tight container 16, a closure 18, and a suitable gasket 20 positioned therebetween and secured together by screws 22.
  • the portion 24 of the container 16 which faces the platen 14 is provided with a capillary porous printing member 26, which has the printing or stamping information formed thereon.
  • the re-inking device is shown in FIGS. 1 and 2 in a non-printing position relative to the platen 14.
  • the solenoid-operated driving means, generally designated 28 is energized by known techniques, its operating plunger 30, which is adjustably and threadedly secured to the closure 18, drives the reservoir 10 and the printing member 26 downwardly as viewed in FIGS. 1 and 2.
  • Suitable springs 34 secured to the container 16, are used to position the material 32 on the platen 14 prior to stamping by the printing member 26 to eliminate smudging of the material 32 due to movement thereof while being stamp-ed or printed upon.
  • the ink reservoir 10 is also moved downwardly, while the U-shaped member generally designated 36 remains fixed relative to the frame 12 and assists in transferring and later closing off the supply of ink to the printing member 26.
  • the closure 18 is apertured to receive bushings 38, in which the legs 40 of the U- shaped member 36 are sealingly and slidably mounted.
  • Each of the legs 40 is joined to a section 42 at one end, and the remaining free ends are secured to the frame 12 by screws 44.
  • the U-shaped member 36 remains fixed relative to the frame 12, while the reservoir and the printing member 26 reciprocate relative thereto when actuated.
  • On the platen 14 is also utilized for transferring and then scaling off the supply of ink 46 in the reservoir to the printing member 26.
  • the portion 24 facing the platen 14 is provided with a recess 48, which is shaped to receive the printing member 26.
  • the recess area 48 has therein a plurality of spaced apertures, into each of which a bushing 50 is sealingly positioned, and each bushing 50 is provided with a passage 52, which connests the interior of the reservoir 10 with the porous printing member 26 as follows.
  • the diameter of the passage 52 is determined by the extent of ink flow necessary to maintain the proper amount of ink in the printing member 26.
  • a fine gauze screen 54 is positioned so that it lies next to the passages 52.
  • the printing member 26 is then positioned in the recess 48 after the screen 54.
  • the purpose of the screen 54 is to distribute the ink .46 evenly over the printing member 26, with which it is in intimate contact.
  • a capillary porous member 56 is positioned in the reservoir It) to cover the passages 52.
  • the member 56 may have the same general shape as the printing member 26 with which it is used, and the member 56 is adhesively secured along its perimeter to the inside of the reservoir 10.
  • fiat areas 58 on the section 42 of the U-shaped member 36 press on the porous member 56 and block the transfer of ink to the passages 52. This action effectively closes olf the transfer of ink when the device is inactive.
  • the solenoid 28 When the solenoid 28 is energized, the reservoir 10 is pushed towards the platen 14, and the U-shaped member 36 remains fixed to the frame 12, as previously explained. This motion has a tendency to cause the porous member 56 to be pulled away from the area 24 of the reservoir 10, to which it is adhesively secured. To minimize this tendency, the section 42 of the U-shaped member 36 is provided with milled-out areas to produce cavities 60, which reduce the area of contact between the member 56 and the section 42.
  • the porous member 56 soaks up ink in the areas immediately adjacent the passages 52.
  • a spring 62 on the solenoid 28 restores the plunger 30 and the reservoir 10 to the position shown in FIGS. 1 and 2. In returning to this position, the porous member 56 comes into contact with the fiat areas 58 on the U-shaped member 36, and the ink in the member 56 is pushed through the passages 52 to the screen 54 and the printing member 26.
  • the completion of the motion of the reservoir 10 to its non-printing position compresses the porous member 56 and effectively shuts oflf the further supply of ink to the passages 52.
  • the porous printing member 26 is secured in the recess 48 by adhesive 64, which joins the entire perimeter of the porous printing member 26 with the portion 24.
  • the extent of motion of the reservoir 10 can be controlled by adjustment of the plunger 30, which is threadedly received in an operating plunger 66 of the solenoid 28, which is secured to the frame 12.
  • the embodiment of this disclosure depicts a porous printing member 26 which is generally flat, it is obvious that curved printing members could be employed.
  • the bushings 50 were made of plastic, and the passages 52 were approximately .OSO-inch in diameter.
  • the ink used was slightly thicker than the ink normally used on microporous printing members.
  • the printing member 26 was made from known microporous rubber used for stamps, and the capillary porous member 56 was made from known foamed rubber materials.
  • the reservoir 10 may be conveniently filled from a filling port sealingly closed by a fastener 68 and suitably vented to the atmosphere by vents 70 in the closure 18.
  • ink reservoir means adjustably secured to said drive means to be reciprocated thereby between printing and non-printing positions relative to said platen
