Definitions

  • the present invention relates to letter openers intended to open mail on three sides and then separate the contents of the envelope. She relates more precisely to the system allowing the extraction of the content of the envelope.
  • a first method uses one or two cylinders vacuumed by a pump empty. The edges of the envelope are sucked by said cylinders and the contents is thus extracted with great efficiency.
  • the big flaw of this technology is the significant noise level generated by the passage of air in the suction holes.
  • a second method uses the friction of an organ that is interpose in the path of the envelope.
  • This friction can be generated by a pad as in document US-A-3,739,543 or by a brush rotary as in document EP-A-459 590.
  • the friction member is brought into contact with the casing by a mechanism.
  • the object of the invention is to propose an extraction mechanism to particular friction which makes it possible to obtain a compact and little device expensive.
  • the operator can enter the envelope and append it to the open mail, or write the references of the recipient.
  • the rubbing bodies are formed by interpenetrating rollers, which allows a very compact arrangement and easy rotation control lower and upper rollers to obtain the forward drive and rearward.
  • the feeding means may consist of rollers antagonists.
  • first motor to control the rotation of the opposing rollers and the lower friction rollers to which the first can be linked by a kinematic chain with pulley and belt, while a second motor controls the rotation of the friction rollers superiors.
  • the device comprises a higher level upstream of the supply means feeding in pre-cut full envelopes and a lower level of reception of empty envelopes, and in that the means of supply are bidirectional.
  • a sensor detects the passage of the envelope between the supply means and the extraction means.
  • the extractor has a main structure formed by the plates 1 and 1 'and a number of spacers 2 forming a frame.
  • the envelope feed area includes the horizontal plate 3 mounted between the plates 1 and 1 '.
  • the envelope 4 is supplied cut on three sides by a mechanism which is not part of the invention.
  • the feeding device comprises the rollers 5 mounted on the shaft 6 and the rollers 7 mounted on the shaft 8.
  • the rollers 5 are in contact with the rollers 7.
  • the rollers 7 are set in motion by the motor 9 mounted at the end of the shaft 8 supporting the rollers 7.
  • the extraction device comprises the rollers 10 mounted on the shaft 11 and the pairs of rollers 12 mounted on the shaft 13.
  • the rollers 10 and 12 form a sector; that is to say that each roller 10 penetrates slightly in the pair of rollers 12 associated so that an envelope can pass between said rollers, slightly undulating.
  • the rollers 10 are put in movement by the motor 9 via the belt pulley assembly 14-15 and 16.
  • the pairs of rollers 12 are set in motion by the end-mounted motor 17 of the shaft 13.
  • the sheet 18, mounted between the plates 1 and 1 ' serves to guide the envelope from the feed station to the extraction station.
  • Prison 18 supports cell 19 which detects the passage of the envelope to its verticality.
  • the device has a tray 20 for receiving envelopes emptied and a tray 21 for receiving the extracted pus. These two tanks are mounted between plates 1 and 1 '.
  • the control means regulate and synchronize the motors as well as the detection organs. They include preferably a microprocessor.
  • the device is in the starting position.
  • the control means rotate the motor 9 clockwise.
  • the rollers 5 and the rollers 7 rotate in the directions shown by the arrows 22 and 23.
  • Synchronized by the belt pulley assembly 14-15 and 16, the rollers 10 rotate in the direction shown by arrow 24.
  • the loaded envelope 4, previously cut on three sides by a mechanism not forming part of the invention, is taken into account by the rollers 5 and 7 by sliding on the sheet 3.
  • Figure 4 shows the next step. Transporting the envelope 4 continues. The latter passes in front of cell 19.
  • the control then rotates the motor 17 clockwise.
  • the pairs of rollers 12 therefore rotate in the direction shown by arrow 25.
  • the control unit stops the movement of said envelope by stopping the motors 9 and 17.
  • Figure 5 shows the next step.
  • the rotation of the motor 17 is reversed.
  • the pairs of rollers 12 therefore rotate in the direction shown. by arrow 26.
  • the upper part 27 of the envelope being in contact direct with the rollers 12, a loop 28 is formed from the hinge 29 of the envelope.
  • the lower part 30 of the envelope remains stationary with its content since, due to the die formed by the rollers 12 and 10, it is in contact with the rollers 10 which are stopped.
  • Figure 6 shows the next step. Pairs of rollers 12 continue their rotation in the direction shown by arrow 26; the loop 28 grows until the end of the part upper 27 is no longer in contact with the rollers 12.
  • Figure 7 shows the next step.
  • the control unit puts then in rotation the motors 9 and 17 so that the rollers 10 and 12 rotate in the directions shown by arrows 31 and 32.
  • Figure 8 shows the final step. Control unit stops then suddenly the rotation of the rollers 10 and 12. Only a small portion of the upper part 27 of the envelope remains trapped in the die formed by the rollers 12 and 10. This sudden deceleration results in ejection of the contents 33 of the envelope to the reception tray 21. The operator checks visually that the contents of the envelope are well extracted. Two cases occur then present.
  • Figure 9 shows the first case.
  • the extracted mail does not does not include the references of the recipient, the operator recovers the envelope by pulling on the latter to read the address written on the envelope.
  • Figure 10 shows the second case.
  • the extracted mail includes the references of the recipient, the operator then launches the storage of the envelope 4.
  • the control unit sets in motion the rollers 5-7-10 and 12 in the directions shown by arrows 34 and 35.
  • the unfolded envelope then slides under the sheet 3 and is stored in the bin 20 for receiving empty envelopes.
