Definitions

This invention relates to chopper action folding apparatus particularly for high speed large capacity automated operation at the output end of continuous web fed printing or other processing plant.
the object of the invention is to provide folding apparatus which is reliable, efficient and adaptable in operation and which is particularly suited to highly automated control systems for precision high speed operation and having facility for simple and speedy changeover by remote control of operating modes.
chopper action folding apparatus including:
the sensing means comprises a pair of position sensors at respective positions spaced laterally of the feed path and independently responsive to the relative positions of respective spaced parts of said abutment face and signature leading edges, the individual readouts therefrom also being automatically compared to detect skewing of the leading edges and/or of the abutment face.
the sensing means or each said sensor thereof comprises an infra-red detector on one side of the feed path and a light source on the other side, the detector and light source extending longitudinally of the feed path so that the degree of cut off of light reaching the detector is a direct function of said relative positioning.
Said infra-red detector may incorporate a longitudinally extending row of individual detector cells, the number of said cells activated at any time being a direct function of said relative positioning.
the braking means may conveniently include one or more brush elements acting on a face or faces of the signatures in the folding zone in known manner, the regulating means acting to adjust the pressure of the brush element or elements on said face or faces to vary their frictional braking effect thereon.
the regulating means may further include timing means whereby not only said relative positioning of the abutment face and leading edge is detected but also the velocity at which the leading edges approach the abutment face and/or the rate at which the leading edges are being de-accelerated by the action of the braking means with consequent feedback adjustment of the latter.
the chopper action folding machine incorporates generally conventional folding mechanism of which the basic components are shown in Figure 1. Flights of rotatably driven spaced parallel upper and lower tapes 10 running from right to left as viewed in the drawings carry a stream of successive signatures 12, typically from the output end of a high speed continuous web printing press.
the signatures 12 shown for example have already been cut and single folded transversely of the feed direction in conventional cylinder web handling apparatus of the press, the folded transverse edge 14 of each signature leading in their direction of travel along the feed path.
Each signature may be single or multi-sheet and need not necessarily have been pre-folded if only a fold longitudinally of said direction of travel is required, or they may have been pre-folded more than once prior to delivery to this machine.
a pair of folding rolls 22 defining a central nip longitudinally of the feed path and rotatably driven so that sheet material tucked into the nip will be engaged thereby and drawn out of the feed path to be delivered downwardly to further onward conveyor means not shown.
rolls 22 are knurled and include grooves carrying further conveying tapes.
a vertical chopper blade 24 Acting in conjunction with rolls 22 is a vertical chopper blade 24.
Blade 24 is guided for vertical movement into and out of intersection with the feed path in alignment with the nip between roll 22 and is operated by conventional drive means not shown in the drawings, typically a rotating crank and connecting rod arrangement.
Other forms of chopper element may be used e.g. reciprocating or "pecking" action choppers.
Operation of chopper blade 24 is phased with the signature feed so that it is lowered to engage the top face of each signature 12 as it arrives fully in the folding zone 16 with leading edge 14 at or in close proximity to abutment face 18.
the longitudinal folding of each signature is initiated by the lower edge of blade 24 as the lower face of the signature is tucked into the roll nip. As soon as it is engaged by the latter it is drawn downwardly and the fold is fully formed by the pressure of rolls 22. In the meantime chopper blade 24 has been raised ready for the next cycle.
a typical high speed web printing press operates at a throughput speed of over 12 metres per second producing over 72 thousand copies per hour, thus it will be appreciated that each stream of signatures 12 must be moved rapidly away from the press and must be handled and processed with the greatest possible speed, accuracy and reliability. Any misfunctioning at the output end could involve close down of the entire printing line with consequent waste of time and materials. It is also important that any necessary adjustments can be made easily and accurately while the system is running at full speed and preferably by remote control with full and easily comprehensible read-out of operating parameters and clear warning of any faults or malfunction.
each signature 12 as it reaches the folding zone 16 must be brought to a halt or near standstill to enable it to be folded and removed from the feed path without it being damaged by forceful collision with headstop 20 and to ensure that the fold is properly and accurately formed.
the apparatus therefore includes braking means (not shown in Figures 1 and 2) which includes brushes 26 positioned in the folding zone to bear frictionally on the upper, and possibly the lower, faces of the signatures between tapes 10 on each side of chopper blade 24. The friction of brushes 26 brings each signature to a halt or near halt as folding takes place.
the braking pressure can be adjusted by varying the brush pressure through a servo unit 28 respective to each brush or group of brushes.
Chopper blade 24 may also contribute to the braking effect, in which case it may be regarded as part of the braking means because it also frictionally engages the top face of the signature while it may still be on the move and this is another factor affecting the braking force required.
the chopper blade and/or the other chopper or folding elements serve as the braking means alone and the braking effect may be adjusted by regulating the phasing of their folding action.
the apparatus further includes control means 30 which incorporates position sensing means shown diagrammatically in Figure 2 and 3.
Said means incorporate position sensing means comprising a pair of infra-red detector units 32, in this example located immediately below the feed path at the upstream end of the folding zone 16 just below and extending longitudinally downstream from abutment face 18 of headstop 20. Units 32 are spaced laterally apart to each side of the centre of the feed path.
Each unit 32 comprises a row of individual infra-red detectors, for example 14 in number pitched at 1mm intervals longitudinally of the feed path.
An infra-red light source 34 is positioned above the feed path relative to each unit 32, the emission therefrom being directed downwardly to shine over and somewhat beyond the full area of the respective unit 32. In some constructions it may be preferred to arrange units 32 above the feed path with the light sources below it.
the signal from each individual cell of each unit 32 is fed to a signal module 34 of control means 30 where the signals are processed, the output therefrom being applied through a regulating module 36 to operate the servo units 28 which adjust the braking pressure of brushes 26, and also to provide a visual read-out of operating conditions on a display screen at a control station 38.
a lefthand group of the individual infra-red cells of units 32 reads the position of the abutment face 18 and also, as there are two laterally spaced units, provide a check of whether said face is at right angles across the feed path or skewed.
each unit responds to the position of the leading edge of each signature as it slows and nears face 18, the number of cells left unobscured from light source 34 by either headstop 20 or the respective signature 12 giving a measure of the relative positions of face 18 and leading edge 14.
the closest approach of each leading edge 14 to face 18 is read in synchronization with the timing of the action of chopper blade 24, typically when the blade is a few degrees from bottom dead centre.
the sensors detect the disappearing back edge of the signature, a further indication of the operating sequence.
each module can provide a measure, in conjunction with a timing means of processing module 34, of the speed of approach of each signature towards headstop 20 and its rate of de-acceleration as it is brought to a halt or near standstill.
control means 30 will preferably store and compare the signals resulting from successive signatures to detect the rate and effectiveness of automatic adjustments made to the braking means.
Another cause of mis-folding is if signatures arrive at the folding zone out of line or skewed, or with individual sheets or pages misplaced.
the use of the two spaced detector units 32 gives a check of correct leading edge presentation, if one unit has more cells obscured than the other the leading edge is skewed or misaligned.
the regulating module 36 may include provision for setting the rate at which changes are made to operating parameters, in particular the rate of adjustment of brush pressure, proportional to the degree of error detected.
a large error detected by units 32 will result in initial larger and faster adjustment of servo units 28 but as the error is reduced the adjustments made will become much finer so as to avoid, as far as possible, hunting in the control loop. Comparison and averaging of successive read-outs from the detector units 32 also assists in fine and effective accurate adjustment.
the folding action at a given chopper folding apparatus which is part of a printing or other processing plant may not be required.
provision may be made for raising headstop 20 out of the feed path and holding chopper blade 24 in its raised position so that signatures pass straight through the folding zone 16 unaltered. It may still be useful to keep detector units 32 in operation as they will read any skewed misfeed of signatures passing them and they may also provide a feed out of their transport speed at that position.
the display provided to the operator at the control station 38 derived from the output from the sensing means, and from other read out from the control and other systems of the machine will preferably be in an easily understood graphic or picture format along with numerical indications and may show how near each leading edge 14 is approaching headstop 20; degree of skew; delivery speed; presence or absence of signatures; degree of adjustment being made by the automatic control loop etc.
