SIGNATUREOR SHEET COLLATING SYSTEM BACKGROUND or THE INVENTION The present invention relates to an improvement in the collating system monitoring device, disclosed in US. Pat. Ser. No. 71 l,04l,filed Mar. 6, 1968.
In the collating system disclosed in the above-mentioned application, feeders are arranged in an equally spaced apart relationship and are driven in synchronization such that signatures are simultaneously delivered by the feeders onto a collating conveyor. Each feeder is provided with a calipering device to detect malfunctions of such feeder and the several calipering devices are connected into a monitoring device, the latter being adapted to interrupt operation of the system only if there is indication more than a predetermined number of successive malfunctions of any one feederl Otherwise, the continuous high speed operation of the system is not interrupted and the monitoring device instead effects a delayed action rejection of a book rendered imperfect by a malfunction at a station beyond the last feeder of the system.
It has recently been proposed to modify the standard system for which the monitoring device of the above-mentioned application had u'tility by one wherein the feeders are arranged in N groups and such groups are driven out of phase one with another. By this arrangement the torque load imposed upon the drive motor of the system is substantially equally distributed throughout each operational cycle of the system. This new feeder arrangement requires that the "spacing between adjacent groups of feeders be in excess of that between adjacent feeders of each group in order to permitbooks being formed on the collating conveyor to be properly positioned beneath successive feeder groups, as the books being formed are passed through the system.
SUMMARY OF THE INVENTION It is an object of the present invention to provide improvements in the monitoring devices disclosed by the above-mentioned patent application, in order to permit its use with collating systems employing N groups of feeders.
The improvement in accordance with the present invention comprises forming a shift register into N banks of functional elements driven in synchronization one with each of the N groups of feeders, and providing intermediate each bank a spacer functional element permitting delay indriving of each successive bank so as to compensate for the variation in spacing between groups of feeders and feeders forming such groups.
DRAWINGS The present invention will now be more fully described with reference to the accompanying drawings, wherein:
FIG. I is a semischematic side elevational view of a collating system embodying a monitoring device formed in accordance with the present invention;
FIG. 2 is a diagrammatic view of the monitoring device and related components;
FIG. 3 is a diagrammatic view showing the spacial relationship between feeders and adjacent groups'of feeders; and
FIG. 4 is a block diagram illustrating the principal components of the monitoring device.
DETAILED DESCRIPTION FIG. 1 illustrates a signature collating system comprising essentially a series of aligned feeders 10 adapted to deliver signatures 12 from associated magazines 14 onto a collating conveyor 16. Conveyor I6 is arranged tov travel from left to right, as viewed in FIG. I, in order to deliver books of assembled signatures at the right hand end of the conveyor to a book binding facility or the like, not shown.
Associated with each of the feeders 10 is a signature pickup device, not shown, which serves to transfer signatures one at a time from magazines 14 onto a feeder, and a calipering device 18, which serves to detect or sense the occurrence of a malfunction in the delivery of a signature by the feeder onto the conveyor 16. A malfunction may be in the form of a failure of the pickup device to timely deliver a signature to the feeder, the delivery of more than an intended number of signatures, or the delivery of a signature which is rendered faulty because of having more or less than a predetermined number of pages or because of being torn or otherwise mutilated. The structure and mode of operation of feeders 10 and calipering device 18 may be conventional and thus form no part of the present invention. However, to facilitate understanding of the present invention, feeders 10 are shown as being of the type adapted to dispense only one signature during each full rotational cycle thereof, whereas calipering devices are operable to produce a signal, such as the closing of an electrical switch 20 each time a signature delivery malfunction is detected thereby.
Referring to FIGS. 1 and 3, it will be understood that the feeders of the collating system with which the present invention has utility are arranged in N identical groups of feeders. As is conventional, each group includes four feeders, so as to permit the machine to be formed from modules of a size which may be readily fabricated and transported. Thus, for example, if it were desired to provide a conventional 40 feeder collating system, 10 machine modules would be assembled to provide l0 groups of feeders, indicated as 25a-25j. In such an arrangement, the individual feeders forming each group, e.g. feeders l0a-l through'l0a-4 would be simultaneously driven. However, each successive group of feeders would be driven 36out of phase with respect to an immediately preceeding group, such that only one tenth of the total torque load of the system is imposed upon the collating system drive motor, not shown, at any given time and the total torque load is substantially equally distributed throughout each operational cycle of the system. Thus, in FIG. '3 the signature delivery portion of the rotational cycle of feeders 10b forming group 25b is shown as lagging by 36the signature delivery portion of the rotational cycle of feeders 10a forming group 15a.
As in conventional forty feeder collating systems, each of the system feeders may be employed to deliver a different signature, such that as conveyor 16 travels beneath groups 250-25 books having forty different signatures may be formed. It is desired to-form books having fewer than 40 signatures it is merely necessary to withdraw an appropriate number of feeders adjacent the outlet end of the system from operation and disable the calipering devices associated with such feeders, so that a malfunction indicating signal is not generated thereby.
Again referring to FIG. 3, it will be noted that the spacing A between adjacent groups ,of feeders is in excess of the spacing B between the feeders of the respective groups; the difference in spacing compensating for the 36 lag between the signature delivery portions of the rotational cycles of the feeders forming successive groups. This arrangement is necessary to permit conveyor 16 which is driven at constant speed through the same linear distance during each full operation cycle of the collating system, to properly position partially formed books beneath the feeders of the succeeding groups.
Referring to FIGS. 1, 2 and 4, it will be understood that caliper operated electrical switches 20 are arranged to send an electrical impulse to I a monitoring system, generally designated as 30, whenever the feeders with which the switches are associated malfunction in any respect.
To better appreciate the operation and function of the monitoring system 30, reference is not made to FIG. 4, wherein the system is shown as including groups of functional elements 40a40j, which are serially interconnected by spacer elements 42. The functional element group 40a-40j includes four elements, e.g., 40a-l through 400-4, such that the total number of such functional elements corresponds to the number of feeders forming the feeder groups performing the building of completed signature books, whereas the number of spacer elements 42 employed correspond in number to the A spaces between adjacent feeding groups. Further, there is provided an ejector element 44, which corresponds to an ejector or reject station, positioned beyond the last feeder in the series, and one or more intermediate elements'46 corresponding to the stations between the last feeder in the series and the reject station, the purpose of which will be presently apparent.
The elements 40013 40j, 42, 44 and 46 are shifting elements connected serially to form a shift register, wherein functional elements 40 a40j are connected as shown to the shift input signals produced by pickups 36a36j, respectively, Spacer elements 42 are connected through OR gates 48 to shift input signals produced by pickups 36a36j associated with each adjacent group of functional elements. Thus, as shown in the case of spacer element 42 disposed between functional elements 40a-4 and 40b1, an input is received successively from pickups 36a, 36b.
function is achieved in the specific example shown in FIG. 4 by providing a second means in the monitoring system (the first means being the shift register) which is capable of detecting the presence of a train of successive malfunction signals from any one of the switches 20,. which is in excess of some predetermined maximum. For example, in the specific example shown in FIG. 4, any switch which indicates two successive malfunction signals will cause the collating system to be stopped.
This second means, as shown, comprises a plurality of AND gates associated one with each of the shifting elements 40a- 40j. One input to each AND gate, indicated by the reference character 58, is connected directly to the associated feeder detector switch 20, while the other input, indicated by reference character 60, is connected to the transfer leg of the next succeeding functional element. In the case of the AND gate 56 corresponding to the last feeder of the series, the
' second input 60 is connected to the transfer leg of the next Each of the functional elements a-y40j is also provided with an input from one of the detector switches 20 associated with feeders 25a--25j, respectively, so that an information bit" produce by closure of any one of the switches will be inserted into its corresponding element 40a-40j. It will be understood of course that a detector switch 20 is closed only in response to a malfunction associated with that particular feeder. Y
The above described operation may be better understood by referring to FIG. 4 and assuming for purposes of illustration that the third feeder l0a-3 of group 25a experiences a malfunction. Upon the occurrenceof such a malfunction, corresponding switch 20 is closed so as to enter a malfunction indicating bit" into functional element 40a-3. During the next operational cycle of transducer 32, pickup 360 will operate to shift the information bit" to functional element 400-4 by which time conveyor 16 will have transported the book previously rendered imperfect by the malfunction to a point beneath feeder 10 1-4. During the next succeeding operational cycle of transducer 32, pickup 36awill first operate through OR gate 48 to shift the information bit" from functional element 40a-4 to adjacent spacer element 42. After a lag of 36, pickup 36b will operate through OR gate 48 to shift the information bit out of spacer element 42 into functional element 40b-1, by which time conveyor 16 will have transported the imperfect bookinto a position beneath feeder 10b-l.
Accordingly, it will be understood that subsequent to actuation, if any, of any one of detector switches 20, the next operational cycle of transducer 32 will cause shift input signals to be applied to the shifting elements, whereby the malfunctioning indicating "bit is advanced forwardly to the next succeeding functional element of the shift register. Thus, during succeeding operational cycles of the system, the malfunction indicating bit" follows the imperfect book stemming from the malfunction, such that when the imperfect book reaches the reject station, a reject mechanism 48 is actuated to reject the imperfect book, as by means of a solenoid 50 connected through a suitableamplifier 52 to the output of ejector functional element 44. a
The monitoring system is capable of rejecting individual books without causing stoppage of the collating system, while permitting the stopping of the collating system if there is an indication of gross malfunction at any one feeder. This latter succeeding intermediate shifting element 46. It will be appreciated that if both of the inputs 58 and 60 indicate a ma]- function signal, this corresponds to two successive malfunction signals from the same switch 20. In this situation the output 62 of the particular AND gate 56 involved will pass to OR gate 64, which in turn produces an output 66 for actuating a relay 68 serving to interrupt thedrive to the collating system.
It has been found that from a practical standpoint, a train of two pulses from the same switch 20 usually means that a gross malfunction has occurred incidental to that particular feeder. However, if desired, means other than AND gate 56 may be employed to accumulate more than two malfunction signals before effecting stoppage of the system.
It will be appreciated that the presence of the intermediate shifting element 46 is necessary to perform the logic for stopping operation of the system due to gross malfunction at the last feeder. Also, it will be understood that ejector 48 in the particular instance shown in FIG. 4, will be required to be displaced from the last feeder of the series by a distance corresponding to two feeder stations.
Thus, if at any time any one of the caliper devices 18 sends, due to operation of switch 20, an impulse to the monitoring system 30, the shift register will follow" the signature collation or book, which has thus been identified as defective, throughout the extent of the collating system, such that upon arrival of the defective book at the reject station it will be kicked out of the delivery line; and that this is accomplished without any slowdown or interruption of the collating and delivery processes.
