Definitions

  • This invention relates generally to endorsers and more particularly to improvements in endorsers regarding a dle roller mounting arrangement and a die roller operating mechanism including means for selectively controlling the location on the documents or similar articles upon which the die roller acts in transferring indicia thereto.
  • known die roller operating mechanisms are generally unnecessarily complicated and without provision for selectively varying the location of the indicia on the faces of the documents, regardless of variations in the sizes of the documents.
  • the present invention involves ⁇ an improved endorser wherein not only is replacement of the die roller facilitated, but also the die roller operating mechanism is simplitied in construction, more dependable in operation and adapted to permit changes in location of the endorsement or other marking on the documents regardless of the sizes of the documents.
  • Still another object of the invention is to simplify and increase the dependability of the operating mechanism of the die roller.
  • Another object of the invention is to provide means affording selectivity in the location of the endorsement or other indicia on the document regardless of the size of the document.
  • Still another object of the invention is to provide means for acting upon an article moving along a given path of travel a given period of time after the article reaches a given point in the path of travel.
  • FIGURE l is a fragmentary side elevational view of an endorser constructed in accordance with the principles of the present invention with some parts removed and others cutaway in order to show the relative disposition of certain parts and salient features thereof;

  • the endorser 10 is a high speed unit capable of endorsing or otherwise marking a large number of documents in a short period of time.
  • the documents are supplied to the housing 11 by suitable transport means 14 which, in the illustrated embodiment, comprises a pair of supply rollers 16 and 17 and an endless transport belt 18.

  • both plates 29 and 30 will bear the same markings and only one of the plates will print on each of the documents.
  • the die roller 12 will generally rotate only as each document passes through the printing couple 23.
  • leading edges of the documents in passing through the channel 20 from left to right as viewed in FIGURE 1, can enter the printing couple 23 before the die roller 12 begins rotation as a result of the flattened portions 27 and 28 of the die roller.

  • an object of the invention resides in the provision of means facilitating replacement of the die rollers whereby machine ⁇ down time during replacement is reduced and the effort required is minimized.
  • the die roller 12 is mounted on the shaft 13 at a free and unobstructed cantilevered end portion 36 thereof, and the shaft is journalled for rotation in bearing members 37 and 39 situated entirely at an opposite end portion 40 thereof.
  • bearing members 37-39 are constructed and arranged so as to reduce deflection of the shaft as well as to provide the necessary bearing effect.

  • a projection 53 extends from the lever arm to facilitate pivotal movement thereof merely by finger pressure of the operator.
  • the lever arm 49 has formed at the inboard end thereof an abutment shoulder 54 which, in the locked position of the lever arm 50 shown in FIGURE 2, abuts an end 56 of the die roller sleeve 42.
  • the sleeve end 56 is situated inboardly of an outer end 57 of the die roller 12, and pivotal movement of the lever arm 50 within the end 56 is accommodated by the space between the shaft 12 and an inner wall 5S of the die roller end 57.
  • the lever arm 50 When a die roller is being inserted on the shaft 13 the lever arm 50 is pivoted into general alignment with the shaft, and in such aligned position the overall transverse dimension of the lever arm 50 is less than the inside diameter of the die roller sleeve 42.
  • the lever arm 50 is pivoted to the locked position thereof shown in FIGURE 2, and in order to maintain the lever arm in this locked position during operation of the endorser 10 the abutment wall 54 thereof has formed therein a notch 59 for receiving a complementarily tapered end 60 of a locking pin 61.
  • the pin 61 is housed in a bore 62 formed in the shaft 13 and is biased in the direction of the lever arm shoulder 54 by means of a spring 63.
  • a die roller operating mechanism indicated generally at 64 is situated at the end portion 40 of the shaft 13 and comprises a friction clutch assembly 66 and a clutch actuator 67.
  • the clutch assembly includes a drive gear 68 mounted on the shaft 13 and freely rotatable with respect thereto.

  • indexing sleeve 70 Situated on the shaft 13 adjacent drive gear 68 is an indexing sleeve 70 which is locked to the shaft for corotation therewith by means of a locking pin 71.
  • wall 72 of the drive gear 68 is urged into abutting frictional engagement with a complemental radial wall 73 of the indexing vsleeve 70 by means of a biasing member 74 mounted on the shaft 13 outboard of the drive gear 68 and separated therefrom by a collar 76 frictionally engaging the drive gear 68 at a face 75 and freely axially slidable on the shaft 13 and adapted for corotation therewith by the liat 85.
  • the drive gear 68 constantly tends to rotate the indexing sleeve 70 along with the shaft 13 and the die roller 12.
  • the indexing sleeve 70 which is corotatably locked to the shaft 13, has formed thereon a pair of diametrically opposite radial shoulders or abutment surfaces 77 and 78, and mounted on the housing 11 for cooperation with these shoulders is a die latch lever arm 79 of the actuator 64.
  • the arm 79 is mounted for pivotal movement on a fixed shaft 80 and formed at one end 81 thereof is an inturned flange 82 engageable with shoulders 77 and 78 in a given angular position of the indexing sleeve 70 as shown, for example, in FIGURE 3.
  • the arm 79 is -rockable and connected thereto in order to provide such rocking motion lis a solenoid 83 including a reciprocally movable operating rod 84 connected to the arm 79 through a pin and groove 86 and 87 respectively.
  • a biasing member in the form of a torsion spring which is mounted on the housing 11, urges the tiange 82 of the arm 79 into abutting engagement with one of the shoulders 77 and 78 of the indexing sleeve 70, thereby preventing rotation of the sleeve, which is continuously urged into counterclockwise rotation as viewed in FIGURE 3 by the rotation of the drive gear 68.
  • the arm 79 Upon momentary energization of the solenoid 83, however, the arm 79 is rocked to immediately move the liange 82 out of engagement iwith the abutting shoulder of the indexing sleeve 70, whereupon the sleeve immediately rotates with the drive gear 68 for one half revolution, that is, until the iiange 82 abuts the opposite shoulder of the indexing sleeve.
  • the solenoid 83 is momentarily energized or pulsed in timed relation to the passage of the documents successively through the path of travel or channel 20.
  • an electric circuit means is actuated which, by incorporating a time delay system, causes a pulsation of the solenoid 83 to enable the die roller 12 to rotate a given and selectively variable time period after the engagement of such downwardly extending linger of the paddle wheel 32.

  • Capacitor 114 charges at a rate determined by the resistor 112 and the variable potentiometer 113. When capacitor 114 reaches the required emitter breakover voltage of the unijunction transistor 107, the emitter of silicon controlled rectifier 106 conducts to apply a pulse to the gate of the silicon controlled rectifier 106 to render it conductive. T-he silicon controlled rectifier 106 applies power to the solenoid 83 which releases the clutch 66 to rotate the die roller 12.
  • Contacts 118, 118 close momentarily, discharging the capacitor 114 to ensure lacourate operation of the timing circuit 100 from cycle to cycle.
  • Resistors 123, 124 prevent capacitor 110 from recharging until switch 109 has opened, so that if a long document keeps switch 109 closed longer than one complete endorsing cycle, a new cycle may not -be initiated upon the same long document.
  • EIGURE 7 is a graphical representation showing the varlous sequences which occur during the operation of the time delay circuit shown in FIGURE 6.

This pulse 120 is sutiiciently long to ensure energization of the silicon controlled rectifier 105. The pulse 121 indicates the time the silicon controlled rectifier is energized.
  • the silicon controlled rectifier 106 is rendered conductive. This action is indicated by the pulse 122 at the point 25 on the time scale.
