Definitions

  • the present invention relates to an enveloping apparatus according to the preamble of claim 1 and a method for enveloping inserts according to the method specified in claim 8.
  • the invention relates to the manufacturing industry of enveloping machines and/or printers. The invention is, however, not restricted to this.
  • Enveloping of inserts is today done in different ways with different complexity of the apparatuses.
  • a plurality of rollers of different types is typically used to fold sheets of paper to envelopes and/or to fold inserts so that they fit inside the folded envelope.
  • Known enveloping apparatuses may have problems with positioning inserts in the envelopes and can sometimes be perceived as time-consuming, complicated to both manufacture and to use, and expensive. It is thus desirable to achieve an enveloping apparatus with good positioning capability of inserts, which has less complexity, which is cost-efficient, time-efficient and user-friendly.
  • Patent FR2724642 discloses a folding apparatus for folding envelopes out of individual sheets with inserts enclosed in the completed envelope.
  • the folding apparatus comprises four rollers, wherein a first roller is movably arranged to create a space between the first and a second roller.
  • the purpose of the space between the rollers is to let the sheets fall by means of gravity between the rollers and on down into a pocket, which causes a bending of the sheet.
  • the sheet is kept immovable in the pocket while inserts are fed towards the sheet, after which the movably arranged roller is positioned in engagement with said second roller.
  • the bent sheet and inserts are then fed between the second roller in conjunction with a third roller, which causes a first folding.
  • the folded sheet together with inserts are placed in a second pocket and are then fed between the second roller in conjunction with a fourth roller and thereby causes a second fold- ing.
  • FR2724642 discloses an apparatus for folding envelopes with inserts which facilitates the positioning of the inserts in the envelope.
  • the construction shown in FR2724642 relies however on gravity, which means that the reliability in operation cannot be guaranteed. The construction may therefore also result in paper jam and slow paper handling. It can also be considered time- consuming to fold the sheet twice in order to complete an envelope.
  • the object is further to develop prior art to achieve an enveloping apparatus, which comprises less components than prior art, which facilitates the manufacturing of the enveloping apparatus and results in a non-bulky enveloping apparatus.
  • the object of the invention is also to achieve an enveloping apparatus, which in an easy and time-efficient way positions inserts in a correct position inside the envelope.
  • This way is achieved an enveloping apparatus where the same driven roller, in conjunction with two different rollers, both feeds and folds sheets.
  • the folding device of the enveloping apparatus completes an envelope in a fast and easy way by one folding.
  • This way is achieved a compact non-bulky enveloping apparatus, which comprises as few components as possible, which in turn results in lower manufacturing costs.
  • the enveloping apparatus is less complex and results in an easy handling during use and service.
  • the individual axes of the rollers are arranged in parallel to each other, where an imaginary first line between the axis of the first and the second rollers intersects a second imag- inary line between the axis of the first and the third rollers, substantially perpendicularly.
  • a sensor is arranged to detect the position of the folded sheet.
  • the sensor is connected to the motor of the first roller and when the folded sheet is at a predetermined position, the rotational speed of the first roller is reduced.
  • a sensor is arranged to detect the position of the folded sheet and at the predetermined position of the folded sheet, the rotational speed of the first roller is reduced to zero and the first roller is completely stopped.
  • two sensors are arranged in a couple to detect the position of the folded sheet and at a first predetermined position of the folded sheet, the rotational speed of the first roller is reduced.
  • a second predetermined position of the folded sheet is further identified, whereby the rotational speed of the first roller is reduced to zero and the first roller is completely stopped.
  • the senor is arranged downstream the first and the third roller.
  • the sensor is arranged at the guide.
  • the third roller is movably arranged relative to the first roller to achieve a gap between the first and the third roller.
  • the third roller is arranged so that a fixed gap is achieved between the first and the third roller. This way the folded sheet can be slightly opened, the folding angle can increase and a plurality of inserts may easily be fed into the folded sheet as close to the folding line as possible. Thus is guaranteed that inserted inserts are correctly positioned in a pile inside the completed envelope.
  • the third roller is arranged at a movable arm.
  • the third roller is resiliently arranged at a fixed arm.
  • At least the first roller comprises aluminium.
  • At least the first roller comprises composite material.
  • a light roller which makes it easier to drive the whole folding device and easier to reduce the rotational speed of the first roller and thus also the rotational speed of the second and the third roller, when inserting inserts.
  • the enveloping apparatus can be coupled to a printer comprising different paper trays for different paper sizes.
  • the present enveloping apparatus can be used in an efficient way with pre-printed sheets and inserts, and larger sized papers may further be used as sheets for the completion of envelopes and smaller sized papers may be used for inserts.
  • inserts do not have to be folded in order to fit inside the completed envelope.
  • An enveloping apparatus is further achieved wherein the sheet may be provided with an applied frame of toner when being fed into the enveloping apparatus, which frame may be used to achieve an initial adhesion of the envelope already in the folding device of the enveloping apparatus. This results in a time- and cost-efficient solution.
  • the method comprises the step to, after the step of reducing the rotational speed of the first roller, also move the third roller so that a gap is created between the first and the third roller.
  • the folded sheet is this way allowed to be slightly opened and a plurality of inserts can easily and efficiently be fed into the folded sheet, as close to the folding line as possible. Thereby is achieved an insertion of inserts, which results in the inserts being correctly positioned in a pile inside the completed envelope.
  • the step of inserting the at least one insert into the folded sheet suitably means inserting a plurality of inserts arranged in a pile. This way is achieved a time-efficient method for completing envelopes comprising inserts.
  • the step of inserting the at least one insert into the folded sheet suitably means inserting a plurality of inserts, one by one sequentially after each other. This way is achieved a method, which ensures that every insert is positioned as well as possible inside the completed envelope.

  • the sheet A is first fed between the first roller 3' and the second roller 3" on to the guide 9 until the front edge 17 of the sheet A touches the stop member 13 of the guide 9.
  • the sheet A then has a bending and when the first roller 3' and the second roller 3" continues to feed the sheet A, the angular condition between the sheet A, the three rollers 3', 3", 3"' and the guide 9 together with the opposing force of the stop member 13, causes the sheet A to bend more and more.
  • the sheet A has a bending, which is fed between the first roller 3' and the third roller 3"' causing a folding.
  • Fig. lb is shown how the sheet A has been folded and fed between the first roller 3' and the third roller 3"' until the sheet A has reached a predetermined position P, which is identified by a sensor 19 arranged downstream of the first roller 3' and the third roller 3"'.
  • the sensor 19 is connected to the motor M, which drives the first roller 3', and at the predetermined position P of the folded sheet A the sensor 19 communicates with the motor M and the rotational speed of the first roller 3' is reduced to zero, such that the roller is still.

  • the position of the third roller 3"' is adjusted such that a gap 21 is created between the first roller 3' and the third roller 3"'.
  • the gap 21 between the first roller 3' and the third roller 3"' causes the folded sheet A to open slightly and the folding angle (the angle between the opposite halves of the folded sheet) is increased.
