Description

Inserter

The invention relates to an inserting machine for automatic filling of envelopes according to claim 1, and to a method for operating such an inserting machine according to the preamble of claim 15.

Various inserting machines are known from the prior art. For example, WO 2016 /

026712 AI a movable funnel-shaped element, for aligning the envelope on a pannier and Aufziehmitteln to pull the envelope on the pannier.

These are necessary because due to the large distance of the hopper upstream transport rollers to the

Packing bag, the envelope can not be pushed through the feed rollers alone through the hopper completely on the bag. Furthermore, it has been shown that such a construction in particular in the field of

Kuvertaufzugrollen is prone to wear.

It is an object of the present application to overcome the above-mentioned disadvantages of the prior art

avoid and as reliable as possible, little

To provide wear-susceptible inserter. Another object is to provide an inserter with a high flexibility, which can process the large variance of envelope formats and envelope qualities with little or no conversion effort. Furthermore, low manufacturing costs and high reliability were objectives of the invention. An inserting device according to the invention for inserting an envelope content into an envelope comprises, analogously to the prior art, an envelope slot for empty envelopes, a flap opener for opening an envelope flap of the envelope, various transport elements for transporting the envelopes from the envelope slot to a packing pocket on which the envelopes be filled, as well as a feeder, for supplying the Kuvertinhalts to the pannier and in the pannier, wherein the transport organs one, at the

Inserting device K about a pivot axis movably mounted envelope tunnel, with an upper tunnel guide and a lower tunnel guide to align the envelope on the bag, as well as with the envelope tunnel operatively connected pivoting means, and at least one drivable Kuvertaufschubrolle. Furthermore, the

Device Transporting devices for the further transport of the envelope filled with envelope contents.

According to the invention, the envelope transfer roll is in a first position, which occupy the envelope tunnel and the Kuvertaufschubrolle opposite the bag, from below against the downstream end portion of the upper

Tunnel guide delivered and the end edge of the end portion is located in the transport direction T immediately in front of a leading edge of the bag. The distance can be adjusted laterally offset in a range of 1 to 15 mm, preferably between 1 to 5 mm, ie immediately before the front edge of the bag. A lower edge of the end edge can thereby with respect to a plane defined by the guide surface of the bag, ie defined, for example, horizontal plane by 1 to 6 mm, in particular be offset by 2 to 3 mm down. This also depends on the angle of the bend in the end area of the upper tunnel guide. Under deliveries will be here

Non-contact delivery of the roller, depending on the stiffness of the envelope, for example. At a distance of 0.5 to 2.0 mm, in particular about 1 mm understood by a possible

allow low-wear operation of the inserter. The envelope touches the roller due to the arcuate guide and is further transported.

In a raised relative to the first position

so-called intermediate position of the envelope tunnel and the Kuvertaufschubrolle opposite the pannier can take, the Kuvertaufschubrolle can also be delivered from below against the downstream end portion (88) of the upper tunnel guide (82), but now the Kuvertaufschubrolle with respect to the transport direction T immediately before the Front edge (21) of the pannier (20) is located. The center of the Kuvertaufschubrolle can, depending on the selected diameter, 5 mm to 20 mm, in particular 10 mm to 15 in front of the bag edge

are located. In height, the uppermost point of the roller (i.e., the point where the upper horizontal tangent rests) is 0 mm to 12 mm, especially 2 mm to 4 mm

above the top edge of the front edge of the pannier.

In a so-called second position, which occupy the envelope tunnel and the Kuvertaufschubrolle opposite the pannier, they can be pivoted away from the front edge and the transport path in Abtransportrichtung A between pannier and removal means free. The bag can be fixed with the

Inserting machine K be connected. The envelope tunnel may include an area in which the tunnel guides are formed in parallel.

The Kuvertaufschubrolle can with synchronizing means for synchronously delivering the Kuvertaufschubrolle to the

Envelope tunnel, or for synchronous swing away from the

Be connected to the envelope tunnel.

Pivoting means and synchronizing means can each one

Cam and at least one lever, wherein the at least one lever of the pivot means connects the cam to the envelope tunnel and the at least one lever of the synchronizing means the cam with the Kuvertaufschubrolle via pivot points. The levers can each be guided over several pivot points on the cam to increase the stability. The

Cams are driven jointly by a drive arranged on the device via a drive wheel and propellant.

Alternatively, the pivoting means and synchronizing means may each comprise a synchronous motor for synchronously controlling the pivotal movements of the envelope tunnel and the envelope loading roller.

Is the Kuvertaufschubrolle stationary with the Kuverttunnel, so rigid or resilient, connected the synchronizing omitted and the drive interact only with the pivot means. Propellants may be a drive belt, a timing belt or a chain. In principle, all moving parts of the transport system, in particular pivoting and synchronizing means, transport means with drive rollers, such as envelope loading roller, as well as feeding means, such as collection and insertion chain, etc., can be driven by a drive, which simplifies the construction and synchronization of the device.

In the second position, the Kuvertaufschubrolle can be arranged with respect to the plane formed by the guide surface down and the Kuverttunnel with respect to the plane formed by the guide surface upwardly pivoted away. Alternatively, in the second position, the envelope trapping roller and the envelope tunnel may be raised upward with respect to the plane formed by the guide surface

be arranged swung away.

In one embodiment of the invention, the envelope tunnel has an entrance area, in the transport direction T

Downstream then a straight guide area and down thereon then a curve, wherein in

Leadership area and in the area of the curve the

Tunnel guides are formed in parallel. By this geometry of the envelope tunnel, the envelope is ideally supplied to thereby open the envelope in cooperation with a pivotal movement relative to the guide surface of the pannier firmly mounted on the inserter

facilitate. The entrance area may be funnel-shaped to the insertion of the envelope

facilitate. To use the term pair up / down it should be noted here that this is used in connection with an inserter in which the Envelopes with one open, one concerning, the

Flap side of the envelope opposite Kuvertrücken bottom flap are pushed onto the here on the lower side of the bag arranged flap guide. It is understood by those skilled in the art that in an inserter in which the envelopes are pushed with respect to the Kuvertrücken top envelope flap on the bag, the terms used in this regard are top / bottom to reverse the analog reversal and the bag now with a overhead flap guide, as well as the envelope tunnel now, for example, to be installed rotated by 180 ° to the transport axis. In this case, the transport roller described below is delivered from above instead of from below.

Nevertheless, it is obvious to the person skilled in the art that in the case of an inserting device in which the envelope is supplied from below, the terms top / bottom are to be exchanged again in an analogous reversal. Such

Inserting devices are therefore expressly included in the present invention.

The envelope tunnel may comprise at least one drive roller and at least one idler roller for cooperation with a drive roller. The rollers can either be mounted on the envelope tunnel, or the envelope tunnel can be mounted around or on an axis of a drive roller attached to the inserter, for example pivotably. The rotation of the drive roller and the pivoting of the

Kuvertunnels carried out independently of each other, for example. By separate warehouse. The envelope tunnel is shaped so that it leads the envelope against the Kuvertaufschubrolle. This can also be made wide as a roller and, for example, comprise a friction lining. This can be made of rubber, polyurethane etc. or granular surface, eg diamond, tungsten carbide etc.

Can safely transport the envelope formats

Envelope tunnel additionally one or more with the

Kuvertaufschubwalze, in the first and the intermediate position mitlaufende counter-pressure roller (s), which is mounted in one or more recess (s) of the upper tunnel guide or are.

The above-mentioned straight guide portion may be longer than the input portion and longer than the curve-forming portion, for example, the length being between one-fourth and three-quarter envelope lengths (distance between

Envelope edge and envelope bottom) of the shortest to

processing envelope format can be selected.

The upper tunnel guide may extend down the curve beyond the curve and the downstream end of the lower tunnel guide. The lower tunnel guide may extend upwardly beyond the entrance and the upstream end of the upper tunnel guide. The

Swivel bearing of the envelope tunnel can be provided at the upstream end.

A method for operating an inserter, usually includes the removal of an envelope from an envelope shaft, the flap of the one to

Envelope removal opening of an envelope slot next located envelopes, an envelope placed in the envelope compartment with a flap opener is opened, whereupon conveyors transport the envelope with the open envelope flap ahead to a pannier on which the envelopes are filled and the envelope contents by means of a feeder of the pannier to and in this

is introduced. Subsequently, the filled envelope is transported by removal organs.

According to the invention, an envelope tunnel and a

Kuvertaufschubrolle be brought opposite the pannier to a first position in which an end edge of a downwardly disposed end portion of an upper tunnel guide in the transport direction T is located immediately in front of a leading edge of the pannier and the Kuvertaufschubrolle, delivered from below against the end portion in

Transport direction T is operated, causing the

Envelope flap is pushed under the leading edge of the pannier parallel to or in a flat transport angle Wl under a guide surface of the pannier. The angle Wl can also be negative, ie towards the bottom

directed, realized. The angle Wl can be _T - between + 15 ° and -15 °, preferably between -5 ° and + 5 °, be set.

Furthermore, subsequently, in an intermediate step, as soon as the envelope flap is located below the guide surface, the envelope-loading roll and envelope tunnel are lifted into a so-called

Pivoting intermediate position, causing the

Envelope roll in the direction of the transport path T located just before the leading edge of the pannier and the envelope flap in a transport angle W2 from

Envelope tunnel is fed to the pannier. In this case, the Kuvertaufschubrolle is still delivered from below against the downstream end portion of the upper

Tunnel guide in the transport direction T operated, whereby the envelope is opened for pushing and loading with envelope content on the pannier. The transport angle is directed in the transport direction T for the Kuvertvorderseite with the flap downwards angle W2 and for the

Kuvertücken horizontal, or directed upwards W3. The angles are each from the tangent of the last one

Touch point with the Kuvertaufschubrolle to

Pannier set out. Angle W3 is between 0 ° to 20 °, in particular 5 ° to 10 °.

In a so-called second step, after completely pushing the envelope onto the packing bag,

Kuvertaufschubrolle and Kuverttunnel are pivoted away in a so-called second position of the front edge, whereby the transport path is released in Abtransportrichtung A between the pannier and removal means. In the second step can be the Kuvertaufschubrolle

with respect to the plane formed by the guide surface down and the envelope tunnel with respect to the plane formed by the guide surface are pivoted upward. The pivoting movements of Kuvertaufschubrolle and Kuverttunnel can by swiveling and

Synchronizing means are synchronized. Alternatively, in the second step, the envelope feed roller and the envelope tunnel can be pivoted upward with respect to the plane formed by the guide surface, for example jointly with the pivoting means.

In another embodiment of the invention, in the region of the lower tunnel guide on the envelope tunnel, with this pivotally mounted, driven transport roller, in a position, for example. In cooperation with a mounted on the upper tunnel guide idler role, an empty envelope through the Tunnel transported in the transport direction T, at the same time, offset in time and / or in a different position with an arranged below Abtransportrolle, also known as

Counter-pressure roller may be formed, further transport a filled envelope in the Abtransportrichtung A. The Abtransportrolle can be designed to be elastic, elastic coated or spring-mounted. This has opposite to the use of usual ones

Circle segments have the advantage that the movement of the

Transfer roll not with the Kuvertabtransport

must be synchronized.

In a further embodiment of the invention, in which the movement of envelope tunnel and push roll, which may also be designed as a pusher roll, as mentioned, are controlled by cams, the cams can also separately instead of a common propellant

be driven (electronic shaft, servo drives, stepper motors), so that by means of parameterization in the Application, the movements on certain envelopes optimized and so the performance can be increased.

As an alternative to the operation of the envelope tunnel and the

Slip roller with two cams, the two cams 90 ^' , 91 ^{' can} also be integrated in a disc, making the system more compact and cheaper.

To facilitate the setting at first time

Commissioning, mechanically precisely adjustable levers are used to transfer the movements from the cams or from the cam disc. This allows re-tuning and optimizing during maintenance work

be made.

In a further embodiment of the invention, the cam of the pivoting device in the so-called

Zero point, i. when the envelope is raised, which corresponds to position two, it is designed to be open at the top to allow easy manual opening and access for troubleshooting.

With regard to the pannier is to mention that this can be made adjustable in width, whereby a greater flexibility is achieved.

In the following, the invention is based on figures

described by way of example. Figures 1 to 5 show

different phases in the filling of an envelope on an inserter according to the invention.

As shown in Figure 6, the envelope 5 according to an embodiment of an inventive method in

Kuvertschacht 11 with the closed envelope flap 8 inserted down. The flap is from the envelope 12

opened and the envelope 5 with opened flap 8 withdrawn from the shaft 11. Then it is in the sheet with the flap open ahead in the Envelope 50th

transported.

The opened envelope flap is in the area of envelope transport 50 and in the further course below, as for example. From Figure 2 can be seen.

The envelope 5 is now, as shown in Fig.l visible with the opened envelope flap 8, or flap leading edge 9 advancing means of roller pair 1, 2 supplied to the envelope tunnel 80. The envelope tunnel 80 is in the entrance area 84 by two initially funnel-shaped converging, then parallel, first straight and then a curve

training, here made of sheet metal tunnel guides 82, 83 formed, which limit the transport path of the envelope against the top and bottom. Alternatively, to further reduce weight, a titanium version,

Carbon fiber composite, in particular made possible from wear-coated carbon fiber composite material.

Alternatively, a design as a guide rods, in particular from the above materials is possible. Through the curve 85, in the present case, the transport path of the envelope is deflected obliquely upward at an angle of approximately 45 ° from one direction downwards in one direction. Upstream, the lower tunnel guide 83 is extended over the pair of rollers 1, 2 in the region of the envelope transport 50. Downstream here is the upper tunnel guide 82 over the interaction region 71 of the Kuvertaufschubwalze 70 and the optional counter-pressure roller 81 out to in

extended close to the front edge 21 of the pannier 20. The counter-pressure roller 81 acts by one, or when using multiple roles by more

recessed cutouts in the upper tunnel guide 82, down the curve 85 outside the tunnel-shaped

The lower tunnel guide 83, however, ends downwards, in the positions shown in Fig.l to 3, immediately in front of the

Cooperation area 71.

Although the embodiment shown benefits for the

Guiding an illustrated type of envelope with medium flap length brings with it, in principle, other configurations are possible here. For example, the counter-pressure roller 81 can even be omitted, since the

Envelope tunnel is designed such that this provides the necessary counterforce to form enough friction on envelope transfer roll 70. Similarly, the curve 85 can also be a larger or smaller change in direction of the transport path approximately in a range of from 30 ° to 60 ° inclusive and the kink 86 in a

Range from 0 ° to 20 °, while preferably be set between 5 ° and 15 °, depending on how far the upper

Tunneling beyond the cooperation area extends. The distance between the substantially parallel

Guides can be chosen between 1 and 5 mm, in particular about 3 mm or vary in the different sections. The length of the parallel section can be between one quarter and three quarters of the minimum envelope length to be processed (distance between envelope bottom 7 and flap edge 10), in particular

be adjusted according to about half an envelope length. The majority of the parallel guidance by the guides 82 and 83 is thereby up the curve 85, whereas the lower guide down here can end immediately after the turn.

The shape of the tunnel is also dependent on the angle and height of the envelope transport 50, which roll diameter is used, etc. Due to such adjustments, the above values may be further varied. Instead of sheet metal, the envelope tunnel can also be made of other materials,

especially to reduce the moving mass. These may include both titanium, carbon fiber material or others, as well as the formation of the envelope tunnel, for example by guide rods. In the further course, the envelope is transported further through the roller pair 14, 15 fixedly connected to the tunnel 80 and introduced into the envelope tunnel 80, as shown in FIGS. 1 and 2. The pair of rollers 14, 15 acts through a, or when using multiple pairs of rollers through a plurality of recessed cutouts in the lower tunnel guide 83 and the upper tunnel guide 82 in

Entrance area 84 of the envelope tunnel 80. At the time of entry of the flap leading edge 9 of the envelope 5 in the envelope tunnel 80, this is in the position shown in Figure 5.

This envelope tunnel is movable up and down around the

Fulcrum of the axis of transport roller 1. This fulcrum is advantageous, but not necessarily mounted on the axis of the transport roller 1.

The movement is so controlled that when the

Flap leading edge 9 reaches the end of the envelope tunnel 80, the envelope tunnel has reached the position shown in Fig.l.

Thus, the flap leading edge 9, and thus the

Envelope flap 8 itself, under the packing bag 20. The envelope is thereby from the Kuvertaufschubwalze 70 with the

(Optional) counter-pressure roller 81 further transported. The envelope transfer roller is provided with a non-slip rubber, polyurethane or corundum covering, which ensures the necessary friction and thus a safe feed. Thus, in many cases can be dispensed with the counter-pressure roller 81, since by the friction lining of the Kuvertaufschubwalze and the opposing force of the upper tunnel wall 82 already sufficient friction is formed.

The movement of the envelope tunnel 80 is controlled so that, as soon as the leading edge 9 of the envelope flap has arrived under the bag, the envelope tunnel 80 and the Kuvertaufschubwalze 70 are raised synchronously, so that during this movement, the envelope through the

Kuvertaufschubwalze 70 further transported and the

Envelope flap 8 is pushed further under the pannier 20. The movements of the envelope tunnel 80 and the

Kuvertaufschubwalze 70 are synchronously upwards at this time.

The movements are synchronous (but in the course of a

Cycle in different ways) controlled by the driven by the same drive cams 90, 91. The trailing cams 90 ^Λ and 91 are shown in Figure 8 on the hand transparently shown cams 90, 91. Trapped curves are here control cams understood in which a

Guided guide pin 96, 97 by both sides

Guide surfaces with little play is directed in a groove-shaped curved path. The execution of the guide pin in the curved path as a role, as shown, is preferred here, for example. As a rotatable roller on a

standing bolt is running. Also possible would be, for example, an external cam with spring-loaded lever. The curves of the cams move via levers 92, 93 and 62, 63 the envelope tunnel 80 and the Kuvertaufschubwalze 70. The pivot points of the levers are 94 and 95, respectively. An advantage of this construction is that both the

Drive the transport rollers 1 and 14 and the

Envelope roller 70 (rollers 2, 15, 81 are loose

idler rollers) as well as the movements of the curves 90 and 91 and thus the Kuvertaufschubwalze 70 and the

Envelope tunnels 80 are made from a central drive. This is inexpensive and due to the fixed mechanical

Coupling, these movements run absolutely synchronously. In the chosen construction, this drive simultaneously drives the collecting chain (which feeds the documents), which increases the reliability (synchronization) and the

Minimized manufacturing costs.

The movement of envelope tunnel 80 and envelope lift roller 70 is further controlled so that before arrival of the

Flap edge 10 at the leading edge 21 of the bag, the upper edge of the Kuvertaufschubwalze and the lower edge of the upper tunnel guide of the Kuverttunnels above the

Packing bag lie, as shown in Fig.2. This movement opens the envelope so that the envelope flap is underneath the pannier and the top flap

Kuvertrücken pushes over the bag. Hereinafter, the envelope is passed through the envelope transfer roller 70

completely pushed onto the pannier 20. The

Position of the Kuvertaufschubwalze 70 and the Kuverttunnels 80 remain in the meantime in the position according to Fig.2. Due to the very short distance between

Kuvertaufschubwalze 70 and pannier 20 and Envelope 80 and pannier 20 is a very well-managed

Transport and a possible buckling of the envelopes 5 due to resistance forces when pushing is safely prevented. Likewise, through this exact guidance even thin envelope papers, wavy envelopes, as well as envelopes of inferior quality can be safely processed. The non-driven counter-pressure roller 81 is fixed on

Envelope tunnel attached and moving with this. It provides the necessary back pressure for safe transport. This counter pressure roller is not for everyone

Envelope qualities mandatory, but helpful to handle the entire range of envelope qualities without further adjustments.

The guide plate 41 shown in the figures has no function for the transport and filling process.

The positions shown in Fig.3 of

Kuvertaufschubwalze 70 and Kuverttunnel 80 correspond to that in Fig.2. These remain in this position until the envelope 5 is pushed completely onto the packing pocket 20. The envelope 5 was further transported here and pushed completely onto the pannier 20.

Once the envelope bottom 7 the envelope tunnel 80 and the

As a result, the envelope transfer roller 70 has left and the envelope 5 has thus been pushed completely onto the packing pocket 20, the position of the envelope transfer roller 70 and the envelope tunnel 80 is changed again. In this case, the Kuvertaufschubwalze 70 is lowered in the direction of a lower end position, while the envelope tunnel 80 is simultaneously raised to an upper end position. This position is shown in FIG.

Kuvertaufschubwalze 70 and Kuverttunnel 80 have reached their final positions and allow so space for the now with an envelope content 13 filled envelope 5 eject against the previous transport direction.

During the pushing of the envelope onto the packing bag, the upper insertion chain 23 with the finger 22 already begins the contents taken over by the collecting chain

inside the pannier in the over the pannier

insert pushed envelope (not visible in the figures). This is controlled so that the insertion already begins before the envelope is completely pushed, the leading edge of the content but only shortly after the envelope has been completely pushed onto the pannier (Figure 3) reaches the envelope bottom or the pannier edge 21 (Fig.4 ). The slower than the Einschubkete running collector chain transports the envelope content

also by fingers. It is located below the upper insertion chain at the level of the bag and is not shown in the figures. The insertion chain 23 continues to run and pushes with the finger 22, the contents completely in the envelope and during the further course, the envelope along with content again down from the bag until the envelope of the transport roller 14 and the underlying counter-pressure roller 30 detected and continue towards the output to the following conveyor belt 31

is transported.

This is shown in Fig.5. The envelope 5 with content 13 has been almost completely pushed by the fingers 22 of the upper insertion chain 23 of the packing bag 20 and is transported by the driven transport rollers 14 and the lower Abtransportrolle 30. It has the driven transport roller 14 a dual function: Together with the underlying transport roller 30th

she transports the filled envelope while

simultaneously with the overhead transport roller 15, the next empty envelope is supplied.

The Abtransportrolle 30 is able to compensate for the thickness of the filled envelope by resilient

stored or resilient in itself is formed.

Instead of a roller segments can also be used here, as they are known from the prior art. Basically, here the term role is used synonymously with roller, i. If one or more rollers are indicated for a particular function, they may readily be replaced by, for example, a broad roller, i. Roller to be replaced. Also, if not explicitly excluded or obviously not otherwise possible, the specification of a role basically always includes a configuration with multiple roles.

Shortly before the pair of rollers 14, 15 is already the next empty envelope 5 can be seen.

Next, the movement of envelope transfer roller 70 and envelope tunnel 80 begins again in the direction of the position in Fig.l. In the process, the driven transport roller 14, transport roller 15 and

Counter-pressure roller 30 from, so that the envelope with content 13 then comes to lie on the conveyor belt 31, which then the envelope 5 further to the optional

integrated stations flap closing, gluing and transporting output. The filled, and therefore here usually stiff, part of the envelope 5 has completely left the pannier 20 when this movement of the envelope tunnel begins. The envelope flap 8 can then still be partially in the pannier 20, but is because only one layer of paper

flexible enough to adapt to the movement. Upon completion of the movement of the envelope transfer roller 70 and envelope tunnel 80, the empty envelope has been transported further and the position of Fig.l is reached again. It is in Fig.l on the conveyor belt 31 in the

Recognized envelope to recognize 5. It tries to reach this position as early as possible; but it must be ensured that the longest possible flap of the empty envelope 5 does not match the longest possible flap of the envelope 5 in the removal

can collide.

As a special feature, as in the 3D view of Fig.8

can be seen, the curve of the envelope tunnel 80, by a recess 100 in the outer guide surface designed so that at the time of zeroing the machine corresponding to the position shown in Figure 5, the guide pin, or roller 96 manually upward from the Guideway can be moved. As a result, despite the trapped curve in the zero position of the machine, the envelope tunnel can be raised further, in order to relieve the machine in the event of a jam and remove the jammed material relatively easily and quickly (ease of use). The above embodiment achieves the goals of low manufacturing cost, high reliability and lower

Wear with high flexibility at the same time with regard to various envelope formats and qualities

simple, compact design and mechanically coupled and thus always synchronous movements without control effort.

With lower priority of the goal of production costs, there is the possibility of the mechanical curves being driven by electric drives, e.g. Servo drives to replace with an electronic gear so as to drive depending on the exact geometry of the envelope flap different curves, so that for ideal conditions of the envelope flap the

Performance can be further increased, while still all variants of envelopes are processable. By

Depositing the appropriate parameters in the control of the plant will provide the flexibility and

User friendliness not restricted.

The following, merely by way of example listed advantages result from the use of an inventive insertion device as described herein:

• By reaching up to the bag

Envelope tunnels are accurately guided the envelopes. Due to the very short distance between this guide and the pannier, the envelope can be transferred very precisely, so that higher performance can be achieved.

• Due to the long and very precise guidance of the envelopes in the envelope tunnel, even thin papers and wavy ones can be used

Envelopes are processed safely. Thus, the Change between different envelopes and

Envelope qualities considerably safer.

Through the arch in the envelope tunnel, the envelopes are preformed, so that the deformation in the "open air" directly in front of the pannier is kept to a minimum, which increases the reliability.

In mechanically fixed coupled cam plates, the movements can be synchronized accurately and without any control effort exactly.

If the drive of the cam through the

Chain drive of the collection line (collecting chain and

Insertion chain) of the inserter, a separate drive is saved, which reduces costs and the

Reliability increases, always in sync.

The movements of the two curves can be designed so that they are suitable for all machine-suitable envelopes regardless of the flap shape and flap length without

Adjustment work safely.

The envelope is transported by the envelope feeder until it reaches the pannier and transported in the best possible and safe way without free flight. As soon as that

Due to the dynamics, Kuvert has left the envelope transfer roller

Stop, ie envelope bottom at the edge of the pack edge, in any case sufficiently far, pushed onto the packing bag that only a very short distance remains between envelope bottom and pack edge, which can be overcome by the process dynamics. By the Rotation of the Kuvertaufschubrolle therefore the envelope is completely pushed. It should be noted that within the pannier of the inside running content is securely separated from the outside deferred envelope, so that a reliable operation is ensured without damaging the contents. Even if the envelope, due to the roll diameter, should not be fully pushed onto the pannier, this distance is so small that the envelope content during loading can not touch the envelope, thereby preventing congestion in the pannier is avoided. Only when the loading process is finished does the

Front edge of the envelope contents on the bottom of the envelope and pushes, even from the finger of the insertion chain

driven, the envelope from the pannier.

• The envelope transfer roller is able to remove the envelope completely without

Wear completely on the packing bag, because the envelope is at a standstill, ie after the

Completion of pushing on the pannier the

Has left Kuvertaufschubwalze. This in contrast to the usual today and heavily prone to wear

Envelope winding rollers, which must pull the envelope onto the packing bag and in particular in the

Transition phases at completion of the Aufziehvorgangs and in idle cycles, high wear.

• With two separate curves, the two movements of the envelope transfer roller and the envelope tunnel can be optimally matched. By the Kuvertaufschubwalze the envelope is not pushed through a guide on the bag, but pushed directly onto the bag, which, in comparison to the prior art, the risk one

Paper jams reduced. The route between the

Transport rollers 14, 15 in or immediately after the entrance of the tunnel through which the envelope is pushed into the hopper, to the likewise driven Kuvertaufschubwalze is short. By the latter, the occurrence of adverse forces can be neutralized by the impact of the envelope on the bag.

The extremely short path between the envelope transfer roller and the pannier as well as the envelope tunnel and pannier ensure that even thinner envelope papers will buckle

prevented.

The structure is simply what makes the operation easier.

The mechanical coupling instead of the use of servo drives a cost-effective design is achieved and exact synchronization of all movements in each phase (even during acceleration and deceleration)

Braking ramps) ensured.

By using a width-adjustable bag with a closed guide, such as. In WO 2016/026712 AI described and of all

Envelope lengths suitable envelope tunnel according to the invention is a high flexibility, at the same time high processing reliability against interference and high Quality of processed documents (protection against

Damage).
