Definitions

  • the invention relates to a device for moistening the glue edge of envelope flaps of envelopes, with which the envelopes are closed.
  • Letter post processing systems usually consist of a letter separating device in which the letters are stacked, separated and, if necessary, sealed, a franking and / or addressing machine with optional scales and a storage device, compare DE-M 96 09 167.3.
  • the device according to the invention is an optional part of a letter separating device or a general letter transport device.
  • a franking machine with a device for moistening the rubberized closing edge of envelope flaps is known, which essentially consists of a water container and a support arm as well as a wick, see DE 23 24 182 A1.
  • One end of the wick is immersed in the water tank and the other part is held in the resilient support arm, which has an open edge portion at its end, so that an elongated portion of the wick is exposed.
  • the wick consists of an open-cell, elastic polyurethane foam in which the water reaches the exposed part by capillary action.
  • the envelopes are stacked so that the flaps are open. The flaps are turned against the envelopes by means not described in detail.
  • the envelopes lie flat on a table and are transported along the moistening device by means of a conveyor belt which protrudes somewhat through a longitudinal slot in the table.
  • the flaps of the envelopes are guided below the table.
  • the moistening device is also arranged below the table, the open edge section of the support arm being parallel to the table parallel.
  • the flap is pressed against the exposed section of the wick by means of a resilient humidifier jacket, so that at least the rubberized closing edge is moistened as it passes.
  • the flap then passes through an opening in the table and is pressed against the envelope as it passes by means of a pressure plate and a pressure holder feed plate, so that the envelope is sealed with it.
  • This device only allows a relatively low transport speed for horizontally lying envelopes, since otherwise the capillary action is no longer sufficient for moistening the flaps.
  • the purpose of the invention is to enlarge the area of application.
  • the invention has for its object a device of the beginning to create the type mentioned, in which the letters on one edge be transported standing.
  • a letter separating device 2 has a lateral guide plate 21, on which the envelope 1 rests with its front side, and, on the other hand, a lower guide plate 22, on which the envelope with the envelope edge of the envelope flap 11 stands or is conveyed, see also FIGS. 2 and 3.
  • the letter singling device 2 is divided into a left pre-singling section 27 and a right singling section 28.
  • the envelopes 1 are placed in the pre-separating section 27 as a stack on the lower guide plate 22 and pressed against the lateral guide plate 21 by means of the raised pressure bracket 271 - here inoperative folded down here and pushed laterally in the direction of the separating section 28 by means of the contour rollers 272.
  • drive elements 281 are provided with which the envelopes 1 are pulled off individually.
  • a pair of ejection rollers 282 is arranged, with the aid of which the envelopes 1 are transferred to a subsequent device, such as a balance or franking machine.
  • the device according to the invention for moistening the glue edge of envelopes 1 is arranged and designed in such a way that it can be optionally switched on - with open envelopes - or switched off - with envelopes already closed.
  • the device has a guide unit 23 for the envelope flap 11 of the envelope 1, which is arranged in the path of movement of the two, see also in particular FIGS. 3 and 7.
  • the guide unit 23 essentially consists of a sword 231, a guide plate 232, a moisture accumulator 234 and a pivotably mounted pivoting and carrying lever 237.
  • the pivot and support lever 237 is provided at its free end with two angles 2371, in which the guide unit 23 is suspended.
  • the lever 237 is rotatable on a bearing axis 238 and is resiliently fastened against a tension spring 239.
  • the flap 11 is directed upwards between the sword 231 and the guide plate 232, while the sword 231 rests against the pocket 12 of the envelope 1 in a spring-loaded manner.
  • a sensor 2321 attached to the rear end of the guide plate 232 monitors whether an envelope flap 11 is present or whether the sword 231 has really penetrated between the pocket 12 and the envelope flap 11.
  • the guide unit 23 is pivoted into or out of the path of movement of the envelope 1 by correspondingly turning an actuating button 2372, that is, the device for moistening is activated or switched off.
  • the moisture accumulator 234 is fed from a liquid tank 24 via a supply hose 251.
  • the drive elements 281 are in the Separation section 28 can be seen more clearly.
  • FIG. 3 shows how the envelope 1 stands on the lower guide plate 22 and rests on the lateral guide plate 21 and how the envelope flap 11 runs into the wedge-shaped narrowing opening between the sword 231 and the guide plate 232.
  • the sword 231 and the guide plate 232 are positively connected to one another at the upper end by means of an axis 233, which in turn is hooked together with a first spring 236, see FIG. 6b, into an angle 2371 at the free end of the pivoting and carrying lever 237.
  • the angle 2371 has corresponding holes for this.
  • the other end of the pivot and support lever 237 is provided with two brackets 2375 for rotatable attachment to the bearing axis 238 and for receiving a rod 2376 on which the actuation button 2373 is seated and an actuation lever 2373 for selectively releasing or locking the pivot and support lever 237 is attached.
  • the pivoting and carrying lever 237 is brought into the swung-down end position.
  • a tension spring 239 designed as a spiral spring is suspended, which exerts a force on the pivoting and carrying lever 237 in the direction of the lateral guide plate 21.
  • a switch 2374 for a pump 25 assigned to the liquid tank 24 is arranged in the pivoting range of the actuating lever 2373, see also Fig. 5. When released, the same is switched on with the actuating lever 2373 and switched off when locked.
  • the guide unit 23 is arranged both with the free ends of the sword 231 and the guide plate 232 about the axis 233 and also via the pivoting and carrying lever 237 in a spring-like manner towards and away from the side guide plate 21.
  • the lower end of the sword 231 and the guide plate 232 are arranged at a short distance from the lower guide plate 22.
  • the deflection forces for the rotation of the guide unit are such that small differences in the thickness of the envelopes are as inertia as possible and larger differences in thickness are compensated for as quickly as possible
  • the liquid tank 24 is connected via the pump 25 together with the associated hoses 241, 251, 261, 262 to the moisture accumulator 234 and a collecting basin 26 for draining liquid drops.
  • a supply hose 241 begins at the liquid tank 24 and ends at the pump 25.
  • the supply hose 251 to the moisture accumulator 234 begins at the outlet of the pump 25 and ends above the moisture accumulator 234 on the sword 231.
  • the supply hose 251 is fastened to the sword 231 and is in fluid communication with the moisture accumulator 234 via at least one opening therein.
  • the discharge hose 261 begins at the collecting basin 26 and ends in the pump 25.
  • the discharge hose 262 runs from the pump 25 to the liquid tank 24.
  • the liquid circuit is now closed.
  • An undetectable sensor in the liquid tank 24 signals when a lower critical fill level has been reached.
  • the performance of the pump 25 is adapted to the transport speed and the paper quality of the envelopes 1, as a result of which adequate glueing of the glue edges is achieved.
  • the moisture accumulator 234 is arranged between a holding plate 235 and the sword 231, the holding plate 235 being detachably fastened to the sword 231 and being adapted to the contour thereof.
  • the part of the moisture accumulator 234 located at the rear in the transport direction protrudes beyond the holding plate 235 and protrudes around the sword 231.
  • the protruding part expediently has a wedge-shaped design that grows towards the sword side.
  • the moisture accumulator 234 preferably consists of an open-cell foam. Felt or a corresponding fleece are also suitable.
  • the sword 231 is chamfered in its front area towards the gap opening and tapers at its free end.
  • the sword 231 and guide plate 232 are positively connected to each other on the common axis 233, onto which a first spring 236 is also slid.
  • the spring 236 is designed as a spiral spring, one end of which is supported on the sword 231 and the other end of which is supported on the pivoting and carrying lever 237. In this way, both the sword 231 and the guide plate 232 are elastically supported by the spring 236.
  • Fig. 7 the conditions before entering an envelope are 1 in the humidification area - Fig. 7a - and after entering it shown.
  • First sword 231 and holding plate 235 are on the lateral guide plate 21.
  • envelope 1 both according to the thickness of the pocket 12 from the guide plate 21 swung away and made steeper.
  • the envelope flap 11 glides with its glue edge first on the sword 231 and then on the Moisture accumulator 234 along.
