Abstract

The apparatus for filing or ordering a scale flow of folded, flat printed products from a rotary printing press has sliding teeth formed into a filing comb arranged on both side of the scale flow and fixed to tooth supports and with, in each case, at least one sliding tooth engaging to the left and right of a printed product in the scale flow behind its fold. The tooth supports are fixed to rotatable chains arranged to the right and left of the scale flow. One drum runs laterally along side the scale flow, so that said engagement is permitted. An equal number of filing combs is fixed to the rotary chains and run in each case around two sprockets, at least one being a driving sprocket, the spacing of two teeth on the same rotary chain determining the new scale spacing. The driving sprockets are controlled synchronously to one another with a single rotary speed, so that between the sliding teeth and the running scale flow a speed difference is obtained permitting a displacement of the printed product within the scale flow. The printed product displacement leads to a reduction of the spread or scatter of the scale spacing.

Description

The invention lies in the field of printing technology and relates to a device for arranging a shingled stream of printed products according to the preamble of patent claim 1.

In the case of high-speed production processes, an attempt is usually made to put the product flow in order in order to facilitate subsequent manipulation of the manufactured goods, if not to enable them in the first place. In the case of flat products, as they occur in printing technology, an order system has become established, which is called the shingled stream due to the characteristic nature of the position of the printing products. This stream of shingles is already organized when the product is issued, in which, compared with the example of rotary printing, a so-called lay-off star exits the rotary press, stacking the printed copies on top of one another. The output speed can be (typically) 50,000 to 100,000 copies per hour and is therefore in the field of high-speed production.

The removal of products in the form of an orderly stream of shingles is now an established, well-controlled technique. In principle, it is also suitable for the high-speed range and is used above all where further processing is necessary, or more precisely, where the order placed in the shingled stream is a prerequisite for further processing with the machine stations of a production path that follow in the process execution.

At a processing speed of 15 to 20 copies per second, a malfunction with subsequent disordered jam has a significant impact and can even force the process to shut down in extreme cases. Under various preventive measures to prevent malfunctions, this also requires the correction of scale parameters, in particular the scale spacing. Measures for this are known, for example the use of gravity to generate an orderly movement within the scale flow. For this purpose, the incoming stream of shingles is directed against gravity into a rising ramp and the flat specimens that slide back are pushed up by means of a mechanically guided slide. This scale flow folder mentioned here is a generally fixed part of the system, which takes over the scale flow and releases it in an orderly manner. Such a system part has to be planned into the transport system and has its fixed location within the process after assembly.

However, the aim is a "portable" high-speed scale stream folder, which can extend beyond today's high-end range in terms of processing speed and which, due to the simplicity of its operation, has high to maximum operational reliability. The portability is such that the folder can be integrated into the process in existing plants at the desired location and can be retrofitted in newly planned plants for optimal operation. In the high-end performance range, faults lead to particularly delicate situations, so that the requirements for operational safety are particularly high.

It is an object of the invention to provide such a stream stream folder.

This object is achieved by the invention defined in claim 1 for a device and the operating method specified in claim 13.

The schematic representation as shown in FIGS. 1 to 3 serves mainly to explain the apparatus part of the invention and the functioning thereof. In the illustration in FIG. 1, the shingled stream T with the individual shingled stream elements, for example the printed copies T1 to T6, is guided on a conveyor belt 1 at a speed v1 to a conveyor belt 2 with a belt speed v2. The conveyor belt 2 is here, for example, part of the folder, on which the staggered printed copies T1, T2, T3 are deliberately moved by a comb folder device 5. The printed copies are usually one to several sheets folded one or more times and have a fold or collar 4. This collar 4 is used to order the publications according to the invention. These shingled flow elements brought into the new order (the printed copies) are then transferred to a further conveyor belt 3 at a belt speed v3. Orderly the scale spacing sx, in this case from the delivered scale spacing s2 to a new scale spacing s3, the scale spacing sx being measured from bundle to bundle. Another way of determining the scale spacing is discussed below in connection with FIG. 3. In the newly ordered form, the stream of shingles on the conveyor belt 3 is carried away at the speed v3 not equal to v1 not equal to v2. When the scale spacing is increased, the virtual scale stream length increases, and when it is reduced it shrinks. The rate of change of the virtual length of the shingled stream is compensated for by the different running speeds of the conveyor belts. As shown here, for example, the conveyor belts are endless belts running over rollers R.

Connected to the conveying device 2 is a comb folder device 5, which is described in more detail in connection with FIGS. 4, 5 and 6. In the incoming shingled stream, the individual shingled stream elements Tx are recorded using a counting point 6. If this count is mathematically linked to the (as accurate as possible) scale spacing sx and the scale flow speed v, this results in a scale flow cycle that is synchronized with the higher-level cycle of the printing press, i.e. the delivery cycle of the individual printed products from the printing press, except for statistical scatter is. The entire product conveyor is tuned to this cycle, i. H. The connection of devices, such as, for example, the shingled stream folder according to the invention, takes place in each case according to the predetermined cycle pattern, with which each system part then runs synchronously with the others and the trouble-free product transfer is guaranteed. Finally, above the conveyor belt 3, FIG. 1 also shows a pressure roller 40 pivotably arranged on a roller arm 41, with the aid of which a problem-free transfer of the newly arranged shingled stream onto the conveyor belt 3 is made possible.

Figure 2 shows the device shown in schematic representation in Figure 1 seen from above. The conveyor belt 1 is not shown in FIG. 2. On the side of the conveyor belt 2 there is a comb arrangement device 5 with two mirror folders 21, 22 which are mirror images and which will be discussed in detail later. They behave like left and right hands, pushing the printed copies forward in the stream of scales (in the direction of the arrow). Each of these comb files 21, 22 has a chain 25L for left and 25R for right, running over sprockets 211, 212, 221, 222, on which a plurality of comb-shaped assemblies, the hands or the combs 26L for left and 26R for right are attached. To simplify the illustration, only the modules located on the shingle stream, i.e. in the forward drum, are shown. The two counter-rotating comb binders move the combs, which are boomerang-shaped when viewed from above, and which can also be compared with one hand with a thumb spread, along the stream of scales. They are arranged so that the tip of the comb (thumb) can protrude laterally into the stream of scales. In Figure 2 it can be clearly seen how the combs 26 of the comb files 21, 22 swivel into the side region of the scale flow, then follow the scale flow in its running direction in a straight, parallel or slightly upward slope and finally are deflected such that they come out of the scale flow again swing out. The combs, which run faster than the belt speed v2, attack the print material, for example the scale flow element T3 on the inside of the collar 4 (FIG. 1) and pull / push this to the desired scale distance S3, before they then move to the scale flow element T1, which for transfer to the Swing away conveyor belt already at the speed v3 of the conveyor belt 3, swing out again.

Please note the following. Still looking at FIG. 2, the scale distance of the incoming scale flow is designated S2, S2 'or S2 ", that is, three different scale distances. The stochastic deviations are a function of the storage star, possibly also the transport route, etc., and they can be a spread If subsequent scaling differs to a certain extent, the process speed may have to be reduced to trouble-free operation, or a scale stream folder must be used.

FIG. 3 shows a very helpful way of viewing the scale tolerance. The position of the scale flow elements is determined (measured) from a predefined clock pattern with the clock spacing A. This cycle grid is binding for all units involved and is directly synchronized with the filing from the rotary printing press. The reference point of the printed product to the grid is the front part of the fold or bundle 4 of each shingled flow element, the deviation from the clock grid can be understood as a phase error. In practice, the printed products from the stream of shingles are picked up individually using clamps. If the brackets now work in the pitch A, it is obvious that the collar of the printed product may only deviate from the expected time and position within a certain tolerance range, so that the individual intake from the scale stream is guaranteed. Such a tolerance range is indicated in FIG. 3 with + -delta and, for example, the deviations -S1, + S2 and - S3 are assumed for the scale elements T1, T2, T3. Such scatters are probably due to chance, but are not unaffected by the properties of the drop star and the funding.

According to the invention, the shed is now the incoming scale flow was always changed in such a way that the shift Sx - S3 reduces the spread to the desired level. This can look like this: Smax + a = Sv - s3 = s2 + Sv, where Smax is the measure for the maximum scatter of the scale spacing in one direction (e.g. in the direction of the scale flow) and a is a surcharge or an additional shift from 0 to can be a desired value. This results in the displacement length Sv, which is determined in this exemplary embodiment of the device by the distance between two order combs. Such a systematic shift to the clock pattern A up to the tolerance value + delta behaves like a phase shift by + delta, the scale spacing according to the clock pattern A remaining the same. If the shift also changes the scale spacing, preferably increases it, this results in a slower cycle with the clock pattern A + at the same running speed of the scale flow and, in the case of an adequately increased speed, in turn a clock cycle in accordance with the clock matrix A. This is shown in FIG. 3 for the direction of the arrow v moving scale flow T like this: the scale flow element T1 does not reach the intended position in the clock pattern A, but is still within the tolerance range; the scale flow element T2, on the other hand, has reached the intended position in the clock pattern A, but is still within the tolerance range; the scale flow element T3 likewise does not reach the intended position in the clock pattern A, but is also within the tolerance range. However, if the specified tolerance range is too large for a significantly higher working speed, the shingled flow elements must be rearranged in such a way that the newly created spreading range is smaller. If, according to the invention, the scale flow elements are shifted so far in the running direction of the scale flow that the collar 4 comes to lie in the place of the + tolerance limit, the scale elements have been rectified in one direction. A surcharge a means that shingled flow elements outside the tolerance limit can also be included. This type of rectification of the scale spacing tolerances creates a scale flow, the scale spacing of which is only dependent on the comb file.

In the described process of a consequent increase in the scale spacing, from S2 to the distance K between two ridges, ie s3 = s2 + Sv = K, as shown in FIG. 2, the scale flow is pulled apart, so to speak. It moves at its basic speed v1 in the direction of transport, is accelerated in the scale flow folder, which runs at the speed v2 = v1, relative to the conveyor belt 2 and «grows at a speed Sv / time unit. The rate of increase Sv per unit time is superimposed on the basic rate v1. This requires that the transport speed v3 after the folder must be higher by the corresponding contribution than the transport speed v1 before the folder. However, since the number of copies in the stream of shingles remains the same, the cycle times of the grippers, for example, for picking up the printed matter can also remain the same. The only thing that has changed for the subsequent aggregate is the scattering of the scale spacing, which has decreased, which is reflected in the precision with which the individual printed copies arrive at a certain time at a certain location.

The comb files 21, 22 are now discussed in more detail with reference to FIGS. 4, 5, 6 and with the further assistance of FIG. Viewed from above (FIG. 2), a comb folder essentially consists of two synchronized chain wheels 211, 212 or 221, 222 with a chain circulation 25R or 25L, to which the combs 26R or 26L are fastened. In order to ensure the synchronism of the engaged pairs of combs, a completely slip-free transmission of the drive forces must take place, a positive chain engagement fulfills this requirement. In this exemplary embodiment, eight combs per chain circulation (four each are shown) are arranged at a distance K from one another, which corresponds to the new scale distance S3, that is K = S3. As already mentioned above, the supplement a is determined by the fixed arrangement of the combs. With a differently designed device, the distance K can be made variably adjustable, or combs are spaced according to the clock pattern and only a shift in the sense of a systematic phase shift with v1 = v2 = v3 is provided. However, these are only different embodiments of the device and the operating method.

The two comb files are operated in opposite directions in the direction of the arrow such that the combs of two files move in pairs in the direction of the scale flow T. The angled shape of the combs now allows the lateral engagement of two comb tips, for example in T4 behind one and the same bundle of a folded printed product as in T3, T2, for example. The speed of the chain circulation, to which the combs are attached, is, as already described, higher than the speed of the scale flow due to the increase in the scale spacing (even with a phase shift), as already described. When the comb swiveling around the sprocket engages on both sides in the printed product lying in the shingled stream, for example at T4, this is accelerated (with a jerk) after the comb blades have been placed behind the collar and, as it were, pulled a desired distance out of the shingled formation, so that, like set out above, the spread of the scale distances can be eliminated. This state of affairs is shown in FIG. 2 as follows: the incoming scale flow T with the different scale distances S2, S2 'and S2 "lying in a scattering area is opened arranged the new scale spacing S3 = (S2 medium) + Sv with Sv = Smax + a, which minimizes the scatter at S3. The newly formed scale flow with the scale distance S3 is (advantageously) conveyed at a correspondingly increased speed so that the cycle times specified in the process can be maintained.

Figure 4 now shows the left comb folder 22 seen in the running direction. A number of comb blades 30L stacked one on top of the other by means of spacer rings 31 at a distance from a comb 26L are fastened in a rotationally fixed manner by means of a fastening plate 32 to an endless chain 25L running over two chain wheels 222, 221. The axis 35 of the sprocket 222 shown, or the other sprockets, are mounted in the usual way, here a bearing with two ball bearings 33, 34 is shown. A holding device 36 is used to fasten the sprockets to a support structure in the comb file 22. The comb pairs 26L, 26R, of which only one comb 26L is shown in FIG. 4, are arranged on the side of the product T3 in such a way that with different bundle heights b of the printed product delivered on the conveyor belt 2 with the conveyor rollers R, one or possibly more than one displacement blade / s 30 of one Comb 26L, 26R can engage behind the collar 4. It is of course also possible to use a comb with only a single sliding blade and the working height of the sliding blade in each case on the product, i.e. to be adjusted to the waist level b However, the use of combs 26 with a plurality of sliding blades 30 automatically detects any change in the height of the collar, and an adjustment is also unnecessary, so that a useful embodiment according to the task comprises several sliding blades 30. The displacement blades 30 are approximately 1 mm thick and have blunt edges; the distance from one sliding blade to the other is preferably between 4 to 10 mm, depending on the type of printed product.

FIG. 5 shows two order combs 26L seen from the side or in relation to FIG. 4 from the right. One recognizes the stack of blades of the comb, the individual displacement blades 30L of which, in order to avoid twisting them, are lined up on two holding mandrels 38 between the spacer rings 31 already mentioned. By means of screws 42, the two holding mandrels 38 are screwed onto a fastening plate 32, which in turn is also secured against rotation on the endless chain 25L, here it is a roller chain. It is clear that the solution shown for the comb file device according to the invention merely represents a preferred embodiment and that other similar constructions with means for actively moving the scale flow elements in the scale flow can also fulfill this purpose.

FIG. 6 shows how the combs or stack of blades can be attached to the endless chain, which represents a plan view or the top view of FIG. 5. In particular, it also shows more precisely the shape or better the proportions of the comb blades 30 with a point of contact P, which is the point of contact of the displacement blade with the printed product. The fastening plate 32 is advantageously designed in such a way that it can simultaneously replace the outer plate of the roller chain and thus forms part of the chain. With this type of attachment, it is clear that the displacement blade spacings K have a smallest module and cannot be spaced apart at will. The displacement blade distance K is equal to the reordered scale distance, here K = S3. This newly arranged scale spacing is in itself uncritical, since with the variably adjustable removal speed v3 the temporal scale flow cycle can be set according to the higher-level system cycle.

The displacement of the shingled stream element within the shingled stream requires a relative movement of the element to be shifted and the moving shingled stream. This relative movement is caused by the order combs moving faster than the scale stream. If, for example, the comb blades are arranged at a distance from the clock pattern A, the combs moving faster will cause a phase shift and the scale spacing will remain the same as with the delivered scale flow with minimized scatter. In this case, the conveying speed does not have to be changed, it remains the same as the conveying speed. A correction defect then only occurs at a single scale distance, the scale flow continues with a systematically changed phase. This phase shift can then be communicated to the other units in order to synchronize the system again. The possibility described here makes the comb arrangement device according to the invention usable at any location on the shingled stream, it is therefore unambiguous and simply portable and does not necessarily require an additional conveyor belt 2 and / or a different, if appropriate variable, conveying speed. The comb arrangement device can be arranged on an existing belt.

If, in the embodiment under discussion, three conveyor belts, belt 1 for the feed belt, belt 2 for the comb folder belt and belt 3 for the guide belt are shown at different speeds, for example v1 = v2 <v3, this is only for the sake of illustration and explanation . An embodiment in which only a pair of comb files 21, 22 is integrated into an existing system and which works according to the method of changing the scale distance (higher conveying speed than conveying speed) is briefly outlined below.

If, according to FIG. 4 (or 2), the two comb files 21, 22 are arranged, for example, at an interface at which the products of the shingled stream flow from a feed belt to the If the individual receptacle is transferred to the gripping clamps of a cycle conveyor, the quasi-extension of the stream of shingles can be compensated for by the faster running cycle conveyor chain (higher conveying speed). A counting or detection device 6, as shown schematically in FIG. 1, determines the cycle per unit of time with a known current speed v1, for example S2 (average) per unit of time. The comb folder 21, 22 changes S2 to S3 with a change in the cycle / time unit ratio, the number of printed copies always remains the same. The new phase position is removed from the comb folder and no longer changes due to the shifting of the shingled flow elements. Due to the virtual extension of the shingled stream due to the extension of the shingles, the cycle conveyor chain must run faster by the ratio S3: S2 = (S2 + Sv): S2 = (S2 + S2max + a): S2 in order to take over the same number of copies from the comb folder. This compensates for the quasi-extension of the scale flow.

In a systematic approach, the shingled stream for eliminating the scatter 82, S2 ', S2 "of the shingled distances from the laying star could also be pushed together by the same amount as is pulled apart according to the invention. However, using pragmatic elimination criteria, this variant is not considered to be uneconomical. The expansion variant can be implemented simply, inexpensively and reliably compared to the compression variant; it is preferred according to the task.

FIG. 7 of the series of schematic representations for discussing the invention shows, as in the figures above, a feed belt 1, a comb folder belt 2 and a conveyor belt 3. A product counter or detection device 6 and a pressing or fixing roller 40 pivotally attached to a roller arm 41 the entrance or exit of the scale stream section shown «limit the scale distance transformation zone, ie the area in which the scale distances are changed to reduce the spreading area. For a relative movement between two flat, partially superimposed printed products, frictional forces (static and sliding friction) must be overcome. Although a relatively rapid (jerky) acceleration occurs when the combs 26R and 26L are pivoted into the scale stream T via the chain wheels 25R and 25L, depending on the nature of the material, it may still be necessary to at least remove or at least reduce the static friction forces before pulling out the printed product. Known measures are proposed for this purpose, which are shown schematically in FIG. A measure designated by 60 is, for example, the formation of an air cushion between the individual print copies by blowing or injecting an air flow at a certain angle of inclination (alpha) directly under the collar of the print copy arriving in the scale flow, for example T3, in order to significantly reduce or reduce the coefficient of friction. to be eliminated, so that the printed specimen T2 is separated from the print specimen T3 above by the air cushion in between. An air cushion can also be formed between the print copies T2 and T1 that are already in meshing engagement. The suitable angle of inclination alpha depends on the shape of the collar, the weight of the printed product, its surface condition, etc., so that the angle of inclination is advantageously determined and set experimentally.

A further measure, not specifically shown in FIG. 7, is the reduction of the gravity component due to inclination upwards or downwards, for example by inclining the comb folder belt 2 by a certain angle. A further measure consists in that an advantageous effect is produced by introducing energy which interferes with the sticking of the products, for example the action of vibrations. For this purpose, a vibrating device on the comb folder belt 2 in the area of the comb folder can be used, which is designed and acts in such a way that the stream of shingles in front of and between the comb folders is prevented from falling apart.

With the reference number 50, FIG. 7 shows a further measure in order to carry along additional scale flow elements when the printed product is suddenly moved while maintaining the original static friction. As indicated in FIG. 7 with three downward-pointing arrows under the printed copies T6, T5, T4 (T3 is just to be accelerated with a more or less gentle jerk), a continued restraint of the copies that are not in engagement with a comb blade, e.g. achieved by means of air pressure difference. For this purpose, a vacuum pad extends over part of the comb folder belt 2, on which a part T4, T5, T6 of the printed copies sliding over it are pressed against by the pressure difference, while the printed copy T3 is pulled a bit out of the composite.

All of the measures shown and / or discussed in connection with FIG. 7 are intended to prevent the printed copies accelerated by the comb folders 25R, 25L from changing the shingled stream network in a targeted manner. However, these measures are not mandatory in every case. Their use largely depends on the nature of the printed matter. Such auxiliary units are advantageously arranged switchable on the comb folder device as required.

In the method for operating the comb file device, as well as the file device with individual shifting blades, a speed adjustment of the circulating means with the shifting blades or order combs and / or through a shifting blade distance adjustment of individual blades or order combs on the individual circulating means the device can be set to a scale shifting operation or a phase shifting operation.

For the shed spacing shifting operation, the shifting blade spacing K of the individual shifting blades or the order combs is chosen to be larger (or smaller) than the spacing of a predetermined clock pattern A. Then the circulating means can be operated synchronously with the sliding blades or order combs at a speed which is formed from the ratio “reordered scale distance” S3, K to the “mean value of the original scale distance S2 times the feed speed v1. In the event that the device has an additional autonomous conveyor device, it is advantageous if the speed v2 of the conveyor device 2 running between the comb folder pair 21, 22 is equal to the speed v1 of the feed belt 1 and the speed v3 of the conveyor belt 3 is equal to the speed of the circulating medium or Orbital chain is.

For the phase shift operation, the shift blade spacing K of the individual shift blades or the order combs is selected to be equal to the spacing of a predetermined clock pattern A. Then the circulating means with the sliding blades or order combs can also be operated synchronously at a speed which is formed from the ratio “reordered scale distance S3, K to the“ mean value of the original scale distance ”S2 times the feed speed v1. This results in the same infeed and outfeed speeds. In the event that the device also has an autonomous conveyor device, the speed v2 of the conveyor device 2 running between the comb folder pair 21, 22 can be equal to the speed v1 of the feed conveyor belt 1 and the speed v3 of the conveyor belt conveyor 3 can be the same as the speed of the circulating agent or Circulation chain can be set.
