The inventor

and at the same time HARRIS HALBERT M., WEBSTER and MÓDI BHOGILAL M ,, ROCHESTER patent holder (st. a.) (54) Reproduction and Comparative Equipment 1

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reproducing and comparing device for continuous automatic stacking and comparing an unlimited number of stacked copy files from document sets of the type in which a processing apparatus is provided to produce multiple copies of each a document from a plurality of documents, furthermore a control device including compartments for storing copies in the form of sorted lists, and a conveying device that feeds the piezoelectric device into the sorting device, wherein the sorting device has at least one section for storing copies in advance a specified number of compartments to which one copy of each document is introduced. Before copiers were invented in which the original docu- ment can be reproduced immediately, without the need to prepare the intermittent or the special handling of the document in contact with the specially formulated copy sheets, it was necessary to compile a large number of files. 2 each bundle of him has ten pages, then it was first necessary to make twenty-five copies of all ten pages of the original reproduced document. If further comparisons were made manually, then it was necessary to spread twenty-five first pages into twenty-five separate books. For each of these twenty-five, the second page was then individually placed. This procedure was repeated, except for each of the 25 piles, with a total of ten pages, yielding twenty-five 10-page files. In the case of comparisons made by automatic equipment, the types of equipment used can be divided into two groups. As the first groups meet, all twenty-five copies of the first page are arranged in the sheet feeder, which individually places each copy of the customized tray. Then, the sheet feeder is loaded with all twenty-five copies of the second page, with the sheet feeder indicating the number of drills of this process being that all five of the five pages of the first page are placed in a single tray, all twenty-five copies of the second page in the other. compartments and this is done with copies of all ten pages. Each tray is equipped with its own sheet feeder, so that one copy of each tray can be reliably compared to each of the twenty-five deise-master files.

By inventing photocopiers that are capable of producing an unlimited number of copies from a single original, the need to make all copies before the actual comparison is removed. This way, the first page of the original copier insert is made and a five-digit copy is made. In case the copier is used in conjunction with a comparator or clarifier, the trays of the first side can be placed in individual compartments. Subsequently, by making copies of the second and subsequent pages of the original and storing them in the individual compartments, it will retrieve all twenty-five files.

In addition, devices have already been designed to make individually matched copies of the original document by pre-comparing the pages of the original reproduction documents and gradually inserting the original pages into the copier for a single copy. Thus, each time the copier passes all pages of the original file, one set of copies is assembled at the output of the copier.

However, there are some drawbacks to both comparative copies. Making a large number of aligned files using both a separate stacker and a stacker or copier machine is. necessarily to have a large number of compartments and a very expensive and complicated system to move the compartments or to bring copies to the individual compartments. - only one copy is needed, automatic handling of the original document, coupled with the output of the copier. Thus, if a large number of compared sets of dies are required in this case, the original file is over-manipulated, resulting in increased damage or deterioration of the original documents. The purpose of the invention is to eliminate the aforementioned drawbacks. To create an unlimited number of files of matched copies of original documents. It is a further object of the present invention to reduce the size of a device for making large numbered document sets. It is also an object of the present invention to provide a logical control of the functions of the copier, the device to manipulate the original documents and the stacks in order to make aligned copies of the original documents.

Finally, it is an object of the present invention to improve the continuity of a high-performance copying and comparing device in the reproduction of sheet material.

Accordingly, the present invention is based on a reproduction and comparison device for the continuous automatic adjustment and comparison of unlimited sets of aligned copies from a set of materials in which the processing apparatus is adapted to produce multiple copies of each document from the a sorting device, including a sorting device including a copy storage compartment in the form of sorted assemblies, and a conveying device that transfers copies from the finishing apparatus processing apparatus, wherein the sorting device includes at least one copy storage portion of a predetermined number of compartments to which one is introduced copies of each document.

SUMMARY OF THE INVENTION The present invention provides a copy selector in which a sorting device logic circuit is provided with the copy presence sensors positioned in the assemblies, the logic circuit of the device being connected to the exposable computer via a trigger switch. the control apparatus of the processing apparatus and therethrough with the logical circumferential fading of the copies, the connection of the sorting device to the exposure computer, the connection of the computer to the control circuit, and the connection of the control circuit to the logic circuit are bidirectional.

According to a preferred embodiment of the invention, the esposcomputer is adapted to calculate exposures up to a number equal to the number of compartments in each of the (sorting sets or selected number of copies of the original document, and is expediently coupled to a detection type exposition system. wherein the sorting device comprises at least two folding portions and is provided with a feeder device which simultaneously submits to the processing apparatus one document from a set of documents in order to reproduce it and to return the document to a document in a predetermined order the logic circuit of the control device is connected by a line to a deflector for sending copies to one 214723 and, in addition, connected to the comparative circuits.

The device according to the invention enables the self-optimizing method of folding an unlimited number of copies into the desired sets, allowing the constructional connection of the copying, handling and stacking device in the whole and also constituting a substantial dimensional reduction.

The invention will now be described by way of example with reference to the drawings.

FIG. 2 is a side sectional view of a sorting device.

FIG. 3 is a block diagram of a circuit control assembly for said sorting device.

FIG. 4 shows a circuit diagram of the circuit control circuit of FIG. 3. ...

Fig. 5 is a block diagram of the control of gplens for the purpose of scavenging a single-unit compartment of a sorting device. In order to provide a general description of the reproductive device to which the invention may be used, a further part of the description is shown in Figure 1, illustrating the individual components of a typical electrostatic copying system. formed by a xerographic device. As in all xerographic systems, the light image of the original intended to be reproduced is transferred to the sensitized surface of the x-ray plate to form a latent electrostatic image. Thereafter, this latenlt electrostatic image is induced by a xerographic image producing a barrel and corresponding to a latent electrostatic image on the surface of the xerographic plate. The powder image is then electiostatically. convert it to a recording material, such as a sheet or a sheet of paper, in the melter for the purpose of permanently adhering the powder coating to the surface of the recording material.

The xerographic processing apparatus 11 is formed as a separate unit having all the processing stations arranged in the interior of a single housing. The printing system comprises a reproduction station in which the reproduction is arranged on a glass plate 12 for projection on a photoelectric conductive surface formed by a xerographic band 13. The document is conveyed by a feeding device 15 to recirculate the original document of the bottom of the stack 17 on the storage container 19ke a glass plate 12 for exposure, whereupon it returns to the top of the stack on the storage container; this is repeated until a whole series of original documents has been copied, whereupon the entire described cycle can be performed again as described in U.S. Pat. No. 3,558 51.2.

The imaging light rays resulting from the flash illumination of the document by the δ18 lamps are reflected by the first mirror 20, the changeover lens 21 and the second mirror 23 by the xerographic strip 13, which is in the focal plane of the projection lens 21, and the projected image 25 is indicated by a broken line on the strip 13.

In order to smoothly project the image of the dome from the projection lens 21 to the second mirror 23, a rectangular-shaped vortex is provided in the side wall of the housing 11, which corresponds to a rectangular aperture which is just opposite the abovementioned aperture in a side wall of the printing zone housing, if both said boxes are mutually operatively connected for copying. In order to prevent unwanted penetration of the external light into the interior of the device, the apertures may be provided with suitable world-sized members.

The xerographic strip 13 is slidably arranged around three parallel rotary rollers 27, which are suitably mounted in the frame of the xerographic processing apparatus 11. The xerographic strip 13 can be continuously driven by a motor (not shown) at a suitable speed. the strip 13 with the light image of the document causes the strip of the photoelectric conductive layer to be discharged in places that have been hit by the light, whereby the xerographic belt 13 forms a latent electrostatic image, corresponding to the configuration of the light image projected from the original document. around the rollers 27 comes into the developing zone in which the developing device 29 is located, intended to produce a benign electrostatic image. -l transferring the powder image with xerogr on the recording material, the recording material, such as, for example, an archpapper which has been previously separated from the sheet stack 30, is pressed onto the surface of the xerographic strip containing the powder image. During the transmission of the invoked image, the sheet of recording material and the xerographic strip are moved synchronously. Upon transfer of the image, the sheet of paper is fed to a melting station in which the melter 31 is arranged to melt the powder adhering to the sheet of recording material and thus to permanently stabilize the powder image on the recording sheet. -riál. After the powder image is melted, it is wound through the qtvoir in the housing to the sorting apparatus 32 as described below. The recording material sheets are separated from the stack 30 by means of a separating roller device 26 according to a time sequence, depending on the movement of the latent electrostatic image on the xerographic belt 13.

The copying system may be coupled to the transfer unit 35. This transfer unit 35 is adapted to convert a long paper web coiled into a roll 36 into paper sheets of various sizes, such as a cutting device 37 and a suitable control device. a system (not shown) arranged to control the cutting operation and the insertion of the individual sheets into the effective engagement with the separating cylinder 26. The operative action of the individual units coupled to the copying system is ensured by joining the casings in which the units are and spaced openings in the wall to allow perfect co-operation of imaging light beams and sheet conveying paths between system units. In order to prevent unwanted movement of said system units during their operation, these units may be provided with safety clamps; the units may also be provided with interlocking latches to align them with one another and to interrupt the operation. system in the event of a possible breach of the system. In order to facilitate the handling of the unit, these units are equipped with independent wheels and brakes; the movement of the units for the purpose of bringing them into mutual operative engagement is thereby greatly facilitated.

As shown in FIG. 2, the sorting device 32 comprises a base frame S1 which carries the top sorting selector 53 and bottom (sorting assembly 55. The bottom sorting assembly 55 includes a frame structure that delimits the series). In the present invention, the upper sorting assembly 53 comprises a frame structure which defines a series of compartments 59 for making copies.

Copies enter the sorting device through a 32 hole formed in the frame of the bottom class of the assembly 55. Copies continue to pass through the guide elements 63 and a pair of carrier rollers 65 and 67 which direct their movement towards the horizontal conveyor 69, which is a plurality of horizontal motor-driven belts 71 153 (see Fig. 4). The horizontal strips 71 are located above the copy path, with the freely rotatable roll 73 located beneath the path of said copiers. Cylinders 73 are disposed within the horizontal strips 71 and pressed by spring elements. downwardly to provide effective traction by inter-horizontal bands 71 and transported bays. Copies carried by the horizontal bands71 are deflected downwardly into respective compartments 53 of the gate 76 that are actuated, i.e., set in the path of copy movement, solenoids whose operation is controlled by a logic solenoid control circuit (FIG. 5). The solenoid control logic circuit is always released by passing a copy from the horizontal transporter 71 to the socket, causing the light beam to be interrupted between the light source 78 and the phototransistor 80. The interruption of the light beam and its re-establishment always result in the retracted gate 76 and the subsequent slide being retracted 76 to the path of copy movement. This is repeated for as long as the last copy is stored in the respective compartment 59 of the triple device 32.

The upper sorting assembly 53 includes a transverse 115 which is formed by a horizontal belt 117 driven by a motor drive 167 (see FIG. 4) and which is disposed above the movement of the copies and a free rotatable roller 119 is located beneath this path. cylinders 112 are provided which are located within the horizontal bands 117 and which are designed to provide effective tractive force between the bands as in the case of the rollers 74. The gates or fingers 123 serve to deflect the copies into the respective compartment 59; a solenoid control logic circuit including a light source 125 and a phototransistor 127 is provided. A vertical transporter 129 is provided to transport copies to the upper sorting assembly 53, formed by vertical strips 131 moving opposite the cylinders 133. Said vertical translator 129 receives copies in the case of a defective member 135 which is stopped can be adjusted to deflect the pie upwards as described below.

The horizontal strips 71 are arranged in a rotatably mounted housing 137 attached to the frame by one or more hinges. Similarly, horizontal strips 117 are arranged in a rotatably mounted housing 141 attached to the frame by one or more hinges. In accordance with the essence of the invention, the sorting device 32 is capable of producing unlimited production-matched sets of copies from a pre-matched set of original documents. Said sorting system permits the continuous comparison of the sets of copies by alternating sorting in the upper and lower sorting assemblies 53, 55 (such that while one sorting assembly is emptied, the second sorting assembly is filled. Next, the system of control circuits in Figs. 3 to 5 will be described. The operator selects the sorting operation method by pressing the Sl switch to select the operating mode (see Fig. 1). Press the S3 copy number selectors (see Figure 1) to select the desired number of copies from each original document. When the Sl switch is turned on, the sorting device logic 301 is connected (see Fig. 3). with the sensors 303 and 305, which are phototransistors similar to the phototransistors 80 and 127 mentioned above, and light sources 306 and 307 are aligned with sensors 303 and 305. If there is no copy in the sorting compartments 53, 55, the light rays of the light sources impinge on the light sources. 306 and 307 to sensors 303 and 305 connected to a sorting device 101 by a sorting device 301. If one of the two sorting assemblies is dialed, optionally, if both sorts of sorts 53, 55 are free, the sorting device logic circuit 301 is ready to initiate system operation. After pressing switch S2, computer 309 calculates exposures of the bulbs 18 until the number, equal number of trays 59 in each of the triple reports 53, 55, or the number of copies of the original document that has been selected by pressing the copy number selector S3, taking one of the two, which is smaller. It goes without saying that the exposure counter 309 may be coupled to a detection type detection system. Thus, the logic circuit 301 of the sorting device signals the control circuit 311 of the xerographic processing apparatus 11 "whilst" the original document delivery circuit logic circuit 313 associated with the original dispensing apparatus 15 signals "to bring another original document to the board 12. "

After another original document has been brought to the plate 12, the logic circuit 311 signals the original feed control to the document logic circuit 311 of the processing xerographic apparatus "to count the bulb exposure 18". This exposure operation is repeated until the original document feeder 15 has removed the last original stack document 17 from the plate 12, whereupon the sorting device logic 301 again queries the sensors 303 and 305 to see if there is an empty sorting system. . If empty sorting assembly is available, then the above procedure continues until the entire copying operation is completed. If, at any time during the copy operation, a loose sorting assembly is available, this means that the aligned files have not been removed from the sort report shelves, or the three-way reports, then the sorting logic circuit 301 signals the logic circuit 311 to the workstation. the xerographic apparatus and the original document management control circuit 313 "wait" until some sorting assembly is released. At the moment when the free sorting assembly is available, the signal from the sensor 303 or the sensor305 is taken over and the system operation continues automatically as described above.

The signals from the photoitransiistors 80 and 127 of the counting falling into the compartments 59, thereby enabling the control of the motors 167 and 153 as well as the deflection member 135, are controlled by the respective signals 405, 409 and 413 coming from the sorting device logic 301. FIG. 4 illustrates the motor circuit in detail. The motor 153 has a triac Q1 and through which the motor is connected to a power source; The motor 167 also has a triac Q2 through which it is also connected to the source 411. The relay switch signal 409, whereupon the triac Q1 becomes conductive, as a result of which the actuator 153 is coupled to the source 411. The signal 405 is also used in the same way. to connect relay K2, thereby making the triac Q2 conductive, followed by motor 167 connecting to source 411. Logic circuit 301 of control device also provides signal 411 for deflection member 135 at the inlet of the sorting device to set such a path of copy movement that matches the running of the respective engine.

Copies are transported along the selected path of their movement, with the first coping to the first compartment of the selected class of the digit. The 80 or 127 phototransistor detected by the gates 76 or 123 of the respective lower or upper sorting assemblies 55 or 53 is provided to the corresponding controller computer 415 or 417. The sorting computers 415 and 417 (see Fig. 5) are connected to the respective decoders 419 and 421, which in turn are connected to the respective solo -oid devices 427 and 429 via respective drive circuits 423 and 425; the solenoid of the respective parallel bar is activated via said members in response to the phototraser signal 80, 127.

At the same time, corresponding signals 350a 351 are fed from the sorting device logic circuit 301 to the comparator circuits 433 and 435. The comparator circuits 433 and 435 also receive signals from the respective classifier 415 and 417. If the number of signals does not match, the corresponding zero signals are inputted to the sorting computers 415 and 417, respectively. The number of signals indicated agrees when the number of classified copies of the skulls made from the given number. an individual original document. By the method of the invention described above and using the apparatus for carrying out this method, it is possible to produce aligned sets of copies from a pre-aligned set of original documents, without the intervention of the operator, except for emptying the compartments of the control assembly. So far, the number of matched sets of copies has been limited by the number of ses-tav and! count the compartments of these sorting locations that could be arranged in the adjacent copy machine. In the case where the original documents are automatically returned according to the invention, it is possible to alternately use only two-class reports for receiving the matched copies so that while the sets of copies are compared in one sorting set, the copies of the second sorting report are already aligned removed. By coordinating the dispensing apparatus for circulating original documents with the sorting assemblies of the present invention, the overall efficiency of the copier is significantly improved with high-speed copiers using automatic original documents.

It goes without saying that the scope of the invention is not limited to the embodiment described.
