Description

  The present invention includes a first conveying device having a sealing unit that seals a sheet against a sheet layer that does not slip significantly, and is disposed rearward in the transport direction of the sheet layer on the first conveying device. And a second transport device having a deflecting unit for deflecting the tracking end of the sheet layer, and the second transport device is disposed rearward in the transport direction of the sheet layer so that the sheet layer adheres vertically. It is related with the conveyance apparatus of a sheet layer provided with the 3rd conveyance apparatus by which the scale flow which consists of a sheet layer is supplied to a storage area so that it may be blocked | prevented reliably. This is achieved by forming a sheet stage drop stage between the second transport device and the third transport device.

  The present invention further relates to a method for forming and transporting a scale stream composed of a sheet layer.

  In a suitable conveying device of this type, a continuous flow of sheets or sheet layers coming from the transverse cutter is supplied to the accumulation area, and this type of conveying device operates at a relatively high speed. At this high speed, it is difficult to integrate the sheet layer in the integration region without damaging the sheet layer. In addition, the sheet or sheet layer velocity is significantly reduced during the accumulation, since no undamaged deposition of the sheet layer is possible, and this is regularly done by the formation of scale flow in the sheet or sheet layer. Is called. A paper layer, called a paper clip or short clip, is understood as a flat stack of 2 to 8 sheets of paper or synthetic resin foil and a binder sheet of paper or foil, for example. Especially within the wide product spectrum of paper with a shining or very smooth surface, it can cause damage in transport of the paper layer, in addition to adhesion, unwanted electrostatic charges, ambient conditions, It can be interlocked with a paper processing machine which substantially comprises a horizontal cutting device, a stack storage unit, and a conveying device disposed between the horizontal cutting unit and the stack storage unit. In this case, a special challenge means on the one hand ensuring sufficient top and bottom adhesion of the sheet of paper and on the other hand as little as possible top and bottom adhesion of the paper layer. Adhesion of the upper and lower sheet layers is not a problem in the final storage area.

  Applicant's European Patent No. 1266854 (Patent Document 1) discloses an actually illuminated transport device comprising three front and rear transport devices, the second and second of which are shown. The third transfer device has a lower transfer speed than the first transfer device. These known transport devices include an ionizer in which the paper layer can be electrostatically charged in the region of the first transport device. In the region of the second conveying device, a suction device is arranged in which the paper layer can apply suction air to at least one region of the paper layer. A step is provided between the first conveying device and the third conveying device to form an overlap that generates a scale flow of the paper layer, whereby the paper layers can overlap.

  German Offenlegungsschrift 2 725 547 (Patent Document 2) discloses a device arranged behind a transverse cutter for forming a scale flow consisting of a flat object in the form of a sheet or a strip. This known device has a high-speed running upper belt, which is commonly guided over the supply area and the discharge area. Further, a belt running at a high speed is provided in the supply area, and a belt running slowly at a low speed is provided in the discharge area. This slow running belt in the discharge area is used as a brake belt and produces a scale flow. The high speed traveling upper belt can be slightly adjusted in height by the roll eccentrically supported by its lower side in the discharge area, and can be appropriately adapted to the height of the scale flow that generates a gap for the slow traveling lower belt. Furthermore, this known device has overlapping fingers and a suction box arranged rearward, where the suction box can be adjusted in the transport direction or opposite to the transport direction. Furthermore, the brake roll arrange | positioned at the upper side provided with the attached support roll arrange | positioned at the lower side is arrange | positioned back at the suction box. This kind of machine or this kind of method and this kind of equipment are of course slightly suitable for perishable paper and very fast speeds, because this can damage the sheet or the sheet layer. .

  German Patent Application No. 19945114 (Patent Document 3) describes a device arranged behind a horizontal cutter for forming a scale flow. This known device has an evacuation device, an acceleration upper belt and a lower belt and a suction box with a lower belt arranged rearward and used as a brake belt. In order to adapt to the height of the scale flow to be formed, the distance between the upper belt and the transport plane can be adjusted. Further, the upper and lower belts are formed so as to be adjustable in the direction opposite to the transport direction and the transport direction for adjusting the fur mat.

EP 1266854 Specification German Patent Application No. 2725547 German Patent Application No. 19945114

  Compared to this prior art, the problem of the present invention is that the sheet layer cut from the multi-layered strip can be transported at a very high speed, and this fast conveying speed is stored in a relatively short road section. Creating a transfer device of the kind described above that is reduced to a suitable speed and carefully fed to a storage stack limited by a pre-aligner. In this case, damage to the sheet or the sheet layer and excessive adhesion of the upper and lower sheet layers are eliminated. Furthermore, another subject of the present invention depends on the type of paper to be processed and the characteristics of the fur mat, which are particularly difficult to process, starting from the conveying device described in Patent Document 1 (EP 1266854). It is an improvement of such a device so that it can be adapted easily and easily in a very short time.

  According to the present invention, there is provided a first transport device having a sealing unit that seals a sheet against a sheet layer that does not slip significantly, and a transport direction of the sheet layer to the first transport device. And a second transport device having a deflecting unit that deflects the tracking traveling end of the sheet layer, and a second transport device disposed rearward in the transport direction of the sheet layer, -Transport of the sheet layer with a third transport device for supplying a scale stream consisting of the sheet layer to the storage area in such a way that adhesion of the sheet layer is reliably prevented or at least significantly reduced Solved by the device. This is achieved by a structural measure in which a drop layer for the sheet layer is formed between the second transport device and the third transport device.

  Instead, for good integrity, it has been shown that the concept “blocking unit” is not limited to an ionizer, but in particular a unit based on adhesion can also be provided by the support of a pressing roll. On the other hand, different types of deflection units are already known in the prior art cited here, among others: rotating / periodic overlapping fingers, blowing air nozzles, elastically supported pressing rolls, ionizers And a different suction device.

  A particularly preferred embodiment is that the third transport device is parallel so that at least two transport side portions of different heights are formed, so that another drop stage is now formed between these transport side portions. Provided when including first adjusting means for deflecting the disposed conveyor belt.

  Another particularly preferred embodiment is that the third transport device has a second adjusting means for extending the transport-side part adjacent to the second transport device and shortening, i.e., reverse, the transport-side part connected downstream. Given when you have.

  More particularly, each first adjusting means includes at least a turning roll and an elevating means, and each elevating means is formed as a linear actuator, in particular as a pneumatic cylinder, and is provided in a separate starting part.

  Preferably, the second adjusting means has a linear driving means including a carriage movable back and forth. As a suitable linear drive means, an embodiment as a rack / gear drive means is provided, the rack being fixedly supported on a support and the gear being rotatably fixed to the carriage. Optionally, a toothed belt linear unit which is particularly easy to handle can be provided here.

  In particular, one or a plurality of first adjustment means are supported by the second adjustment means so as to be movable horizontally back and forth.

  Finally, preferably, the first, second and third transport devices each include a conveyor belt spaced in parallel across a number of transport directions, which are common in the simplest case. A common group to which the first adjusting means is attached is formed. In another configuration, the conveyor belt is divided into at least two groups, each group having a first adjusting means. However, maximum flexibility can be achieved with respect to the formation of configurable conveyor belt groups, so-called belt carpets, especially when the number of first adjusting means coincides with the number of conveyor belts.

  According to the invention, the paper processing machine comprises at least one previously shown transport device. This type of paper processing machine is used in particular for unwinding, cutting and stacking a roll or rolls of paper and finally feeding it to a reworking machine such as a packaging machine or printing machine.

This task further includes the following steps:
・ For transportation that does not slip and slip significantly, the sheet is sealed against the sheet layer,
-Transporting the sealed sheet layer to the overlapping area where the continuous sheet layers are stacked in the transport direction;
Deflecting the preceding sheet layer over the trailing edge in the transport direction of the preceding sheet layer and tracking and transporting the subsequent sheet layer to form an overlap;
-Forming and transporting the scale flow of the sheet layer, comprising transporting the stacked sheet layer to the first transport side portion of the transport plane disposed deeper in the subsequent transport device under reduced adhesion between the sheet layers Solved by the method.

  A particularly effective adhesion reduction between the sheet layers, under further adhesion reduction, re-transports the sheet layer from the first transport side part of the carry-out belt to the continuous second transport side part placed deep in the carry-out belt Is achieved by doing

  Preferably, the position of the delivery point or the drop stage between the first transport side portion and the second transport side portion of the carry-out belt is adjusted in the transport direction or opposite to the transport direction, and the first transport-side portion of the carry-out belt is adjusted. And the height difference between the second transport side part occurs depending on the fur mat and the material of the sheet layer.

  Instead, according to the present invention, in a further configuration, naturally, the delivery point or the drop stage between the brake belt of the second transport device and the first transport side portion of the carry-out belt of the third transport device is the position. It has been shown that the height can be made adjustable.

  Furthermore, it is possible in the same manner to maintain the inventive concept to attach another carry-out belt including drive means to the first and second transport side portions of the carry-out belt, and in some cases it is effective. Or it becomes preferable. The advantage of such an alternative embodiment is that the first transport side portion of the first carry-out belt is moved from the transport-side portion of the second carry-out belt by simple driving means in order to change the overlap length of the sheet layers as much as possible. Can be driven at different transport speeds.

  In contrast, the advantages of the current and next described embodiments are achieved, in particular, here by adjusting means, with a simple measure to create a variable transport side part of two lengths and different heights. Without the need for costly compensation means for a separate conveyor belt, the length increase of the first part is financially the same as the length decrease of the second part.

A schematic representation of a side view of the essential parts of a known transport device of this kind is shown. FIG. 2 shows a detailed view of the overlap carry-out area of an improved embodiment of such a transport device in a first operating state. FIG. 3 shows a detailed view of the overlap carry-out area of the improved embodiment according to FIG. 2 of such a transport device in a second operating state. FIG. 6 shows a cross-sectional enlargement of the carry-out area of an improved embodiment according to FIG. 2 of such a transport device in a third operating state. The perspective view of the adjustment means in the carrying-out area | region by FIG. 2 is shown.

  The invention will now be described with reference to the drawings on the basis of embodiments without limitation of the general inventive idea.

  In each of the apparatuses shown in FIGS. 1 to 5, a paper processing machine not shown in its entirety is handled here, and a multi-layer paper strip is similarly supplied by a carry-out belt to a transverse cutter not shown. Then, the sheet is cut to a desired sheet length by the horizontal cutter. The cut sheet is subsequently guided to a deposition location (not shown) by the apparatus, where it is deposited up and down on the deposition section.

  Instead, for the sake of good integrity, the belt conveyors shown in the figures are depicted as individual conveyor belts for reasons of simplified representation and are given in the following detailed description, but in fact, The groups have conveyor belts that are driven in common and arranged parallel to each other, and such groups of conveyor belts are depicted as conveyor carpets. In the conveyor belt shown and described next, an endless belt driven by individual driving means (not shown) is handled.

  In the following figures, elements having the same function are provided with the same reference numerals, so no new introduction is made in each figure.

  FIG. 1 shows a side view of the essential parts of a known conveying device of this type, which is then shortened and described, the complete specification being described in US Pat. No. 6,066,854. ).

  The paper clip 3 is transported between the upper belt 25 and the conveyor belt 15 in the transport direction A in the direction of the speed reduction belt 45. The upper belt 25 is turned by a turning roll 21 and is driven by a driving roll or a driving unit not shown in FIG. In agreement, the conveyor belt 15 is turned by the turning roll 11 and driven by the driving roll 12. The same applies to the deceleration belt 45 and the lower belt 55.

  For example, a paper clip consisting of a few paper sheets, such as 2 to 8 sheets, is electrically charged to the electrostatic field 32 generated thereby by an ionizer 30 with an electrical connection 31. A sheet is coupled to each paper clip 3. In order to focus the electrostatic field, a counter electrode 34 is provided, among other things.

  A suitably charged paper clip 3 is transported to the overlap area 2 and is pulled down by suction air 44 to the rear area, i.e. to the tracking end, i.e. to the left area in FIG. Brought to the working area. In this embodiment, a suction box 43 is provided to allow suction air to act on the paper clip 3.

  In the overlap region 2, a plurality of paper clips 3 overlap. They are overlapped between the upper belt 25 and the carry-out belt 55 and further conveyed to the right in the transport direction (in FIG. 1), and these paper clips continue to be carefully and slowly stopped on the front stripper not shown. As such, proper sheet deposition is generated. In this case, the speed of the deceleration belt 45 approximately matches the speed of the carry-out belt 55.

  2 and 3 show fragmentary side views of a transport device improved according to the invention with a detailed view of the overlapping carry-out area in the first operating state (FIG. 2) or the second operating state (FIG. 3). In these figures, the supply belt (15), particularly when the delivery from the first conveying device (10) to the second conveying device (40) and further to the third conveying device (50) is expressed more accurately. The delivery from the to the reduction belt (45) and further to the carry-out belt (55) is shown.

  FIG. 4 shows an enlarged section of the side view from FIG. 2 and further shows the drop stages (H2, H3) according to the invention.

  2 and 3 are first divided into a supply area and a carry-out area connected to the supply area downstream, and in this embodiment, a sheet layer (3 not shown in FIGS. 2 to 5). ) Is carried out in the direction of the arrow A shown in the figure, that is, from left to right according to FIGS. The illustrated carry-out area is further divided into three parts (I, II, III), that is, the deceleration overlap area I of the carry-out belt (55) of the three conveying devices (50), the first transport side connected to the overlap area. It is divided into a part II and a second transport side part III connected further downstream.

  The apparatus has a supply conveyor belt 15 which is turned by a turning roll 11 adjacent to the deceleration overlap area I at the end. The decelerating overlap area I has a decelerating belt 45, which is diverted in the transport direction via a diverting roll (not shown) adjacent to the supply area at the upper start and directly on the upper part of the suction box. The next turning roll 41 is guided. As can be seen from FIGS. 2 and 3, the upper side of the deceleration belt 45 is located deeper (lower) by a height H1 than the upper side of the supply conveyor belt 15, which is necessary for the overlap, It is formed on the transport plane.

  The carry-out area has a carry-out belt 55 guided around the stationary turning roll 51. According to the present invention, the upper side of the carry-out belt is located deeper than the upper side of the speed reduction belt 45 by a height H2, so that the leading edge of the clip is slightly flattened when passing through the stepped delivery point. The adhesion between the clips is reduced by, for example, bending or air administration.

  Further, according to the present invention, the upper side of the carry-out belt 55 is provided with turning rolls 56, 57, 58 that can move horizontally and / or vertically. It is operatively connected to the adjusting means 60. The latter adjustment means 60 provides horizontal adjustment of the turning rolls 56, 57, 58, whereby the carry-out area is divided into two changeable transport side portions 11 and III. The adjusting means 60 includes linear driving means formed as rack / gear driving means 61 and 62 and a movable carriage 64, and the rack 61 is fixedly supported by the support 63 and meshes with the rack 61. The gear 62 is moved horizontally by a motor (not shown). The carriage 64 supports the bearing portions of the deflecting rolls 56, 57, and 58 that are finally movable, so that these positions are necessary and coincide with the fur mat, for example, a minimum part length L1 of 500 mm or a part of 1000 mm, for example. It can be adopted depending on the length L1 ′.

  The adjusting means 53 performs vertical adjustment of the turning roll 58 by the lifting means, whereby the transport side part III placed downstream of the carry-out area can be formed at different heights H3 for the formation of steps.

  2 and 3, the elevating means 54 is shown in the uppermost position including the turning roll 58 and the support plate 59. Therefore, in this operating state, the step height H3 = 0. In this uppermost position, the stationary turning roll 51 and the up-movable rolls 56 and 58 are located at a height, so that the transport side including the portions 11 (L2, L2 ′) and III is placed from upstream to downstream. It extends horizontally in one plane of the turning roll 51.

  In FIG. 4, the elevating means 54 is shown in the lowest position including the turning roll 58 and the support plate 59. Therefore, in this operating state, the maximum height of the step is given, and the height H3 is 25 mm, for example. Is the value of In this lowest position, the stationary turning roll 51 and the up-movable roll 56 are further located at a height at which the up-movable roll 58 is located deeper by the value of H3 = 25. The transport side provided with is extended to a diverting roll 51 arranged from the movable roll 58 to the downstream side. This slight gradient is effective for the transporting behavior of the clip with a special paper type, and particularly acts on a storage and stacking unit arranged continuously in a horizontal direction (not shown) at the time of delivery. Another advantage is to maintain a height where the delivery point to the storage area of the sheet layer remains the same.

  In order to take into account different paper types and in particular different grammars or different surface roughnesses here, it is intended to have the number of adjusting means 53 corresponding to the number of conveyor belts 55 of the belt carpet. The lifting means are separately switchable, so that each is adapted to the paper type and / or paper fur-mat-formed by the conveyor belt 55 with suitable groups in action. In particular, the stroke H3 of the elevating means 54 is carried out in an adjustable manner. As a suitable lifting means, in particular here a pneumatic cylinder is provided, which has an adjustable end position attenuator. As the lifting means, selective electromechanical adjustment means such as solenoids, electric cylinders and other linear actuators are considered, and further the linear actuator may have an endless stroke state. The formation according to the invention of a drop stage of variable height H3 is that the flatness between the turning roll 58 with adjustable transport side part III situated downstream of the conveyor belt 55 and the stationary turning roll 51 arranged downstream. This results in rising below the angle, which is not shown in FIGS. If this kind of rise is not desired, it is necessary to provide the stationary roll 51 with vertical adjustment in advance, the height to be adjusted being guided later to the height H3.

  In FIG. 5, the adjusting means 53 is substantially shown in perspective detail. On the support extending over the entire working width of the transport device 50, a number of lifting means 54 are arranged side by side along the transport direction, including turning rolls 57 and 58 and a support plate 59. Further, one carry-out belt 55 is illustrated by a sample.

  Due to the mode of operation of the method of collecting and transporting a sheet layer or paper clip, the following embodiment is given: First, the paper clip 3 is charged by the ionizer 30 so that the sheet of paper clip or paper clip is first charged. Are united. The paper clip 3 is overlapped during another transport of the charged paper clip to the overlapping region 2, and suction air is applied to the rear region of the paper clip 3 transported linearly to the overlapping region. The This occurs because an appropriate suction hole of the speed reduction belt 45 is attached to the working area of the suction box 43 at the moment when the rear area of the paper clip 3 reaches the overlapping area.

  On another transport path, the paper clip 3 is transferred from the second (deceleration) transport device 4 to the third (discharge) transport device 50, in which case the clip 3 passes the first drop stage H2 according to the invention. Before the clip reaches the transport side portion II, L2, L2 ′ of the carry-out belt 55, for example, a decrease in adhesion may occur. The side is guided between the clips 3 by bending or air administration.

  Next, the paper clip 3 is transferred from the transport side portions II, L2, L2 ′ of the carry-out belt 55 to the transport side portion III connected downstream, in which case the clip 3 is moved to the second drop stage according to the present invention. If the clip passes through H3 and is therefore needed, i.e. during the proper start-up of the lifting means 54, before the clip reaches the transport side part III of the carry-out belt 55, another adhesion reduction occurs, e.g. The side between the clips 3 is guided by.

  In another course of the paper clip 3 conveyor, the paper clips are moved together on the storage platform and / or pallet so that they are carefully paper deposited in a pre-aligner not shown in the storage area.
