Description

~88~7 AUTOMATIC BINDING ~ACHINE USING INSERTION TOOLS

DESCRIPTIQN
This invention relates to a binding machine for forming booklets from prepunched sheets, and more specifically, to an apparatus for applying curled-finger ring-type binder to prepun~hed sheets where the binders may be carried in a cartridge.
The use of plastic curled-finger ring-type edge binders for forming booklets with prepunched materials is known. One class of equipment is the office-style punch-and-binding machine as disclosed in UOS. Patent 3,122,761; 3,125,887; 3,227,023; 3,793,660; and 4,645,399. These machines are used to apply ring-type edge binders to prepunched sheets, usually paper, so as to form bound booklets. ~ ring-type edge binder includes an elongated spine having a plurality of curled ~ingers spaced therealong. (See, for example, U.S. Patent 1,970,258.~ Each finger has one end integral with one edge of the spine, and the other end of the finger i5 free but resiliently engages the othPr ~dge of the spine.
In prior art machines, the binder was held in a comb and L-shaped machine ~ingers were manipulatad to engage the binder fingers and to spread them from the spine so as to open the binder for fitting of prepunched sheets onto the open fingers and then to close the fingers so as to ~irm the booklet by binding the sheets together with the edge binder.
German Patentschrift 830~36 and Ge~man Offenlegungsschrift ?362440 disclose a hand operated paper editing device which is axially inserted into the end of a binder for spreading the fingers. U.S~ Patent 2~88~7 2,234,045 shows a tapered hand-operated opening device.
In recent developments an improved insertion tool and portable ~ystem has been developed for opening a binder and a binding booklet. ~See also U.S. Patent 4,900,211 and U.S. patent application Serial NoO 346,918 filed May 1, 1989.) In some circumstances, as in an office,'a heavy-duty, faster and more flexible machine or apparatus is desirable. Moreover, it is desirable ~or such machines to employ a replaceable binder system ~rom which booklets of different thicknesses and different colors can be formed and bound. This requires the selective use of different diameter and/or different color edge binders.
A cartridge system which carries such edge binders is disclosed in U.S. patent application Serial No. 481,857 filed February 20, 1990 and entitled "Cartridge System ~or Tool Insertion Type Binding Machine".
It is therefore an object of this invention to provide an o~fice-style binding machine suitable ~or using an insertion-type tool to open the binder and hind the sheets therewith.
It is another object of this inven~ion to provide an office-style binding machine which is suitable for use with a cartridge carrying binders of differenk types.
These and other objects of this inventi~n will become apparent from the following disclosure and appended claims.
There is provided by this invention a heavy-duty, office-style binding ~achine employing an ins~r tion tool type opening device for forming booklets by binding prepunched sheets together~ This machine is particularly suitable for use with a cartridge which ` 2~8~7 carries the binders.
The machine includes guide means for receiving binding tool car~ridge and guiding a binder in the cartridge to a binding position. Paper guide means are provided for receiving prepunched paper and delivering the same to the binding position. An insertion to~l drum extension, retraction and storage system is provided for storing the different sizes of in~ertion tools and inserting the appropriate tool into a binder at the binding position so as to open the same and receive pre-punched sheets. A clamping system is provided for selective use with binders of varying sizes to assure alignment of the prepunched sheets with fingers of the binder. Sensors are provided in various positions ~o detect the presence of a cartridge, the presence of a bind~x, to determine the type of binder within the cartridge, actuate the insertion tool, and to sense the tool insertion step and withdrawal step. A control means coordinates the operation o~ the bindiny apparatus, namely the cartridge, the paper guide insertion tool, clamp and sensors ~or the purpose of forming a bound booklet.

ON THE DRAW NGS
Referring now to the drawings, the combined binding and punching system i~ re~erred to as lO gener-ally. The apparatus includes a base 12 and housing 14.
The punch system 16 is generally of a known type and is shown in Fig. 1 encased in the lower portion of the housing 14. However, the punch has a sensing provisîon which disables the punch mechanism if paper to be punched is misaligned. This insures that the backgau~e positions of the punched holes is accurate and consistent. The binding system is formed in the upper portion of lg of ~0~8817 the housing. The binder systsm generally includes the cartridge-receiving area 20, the paper guide 22 for receiving sheets of prepunched paper, such as 24, and internally of the housing there is provided the insertion system/clamping system at the binding position as well as the various sensors, ~n appropriate power switch 26 is shown along with the control panel 28.
Binder and Cartridge The binder system generally includes the ring-style binder 30 generally, which includes the binder spine 32 having spaced therealong curled fingers such as 34, 36 and 38. For example, see ~igs~ 2 and 3. A tape-like insertion tool such as 40 is shown in Fig. 2 axially aligned with the binder so as to open the same~ The opening is shown in Fig. 3 wherein the fingers are separated from the rotating spine due to insertion o~ the tool 40 so as to for~ an upwardly facing gap into which paper can be deposited. It is to be note~ that the binder spine has in e~fect rotated ~rom a substantially horizontal to substantially vertical position by the insertion of the tool 40.
Binders 30 can be carried in cartridges, such as cartridge 42 shown in Fig. 4, which are vacuum formed and have a bottom portion 44, top portion 46, ~ront wall 48, hack wall 50, sid~ walls 52 and 54, and a peripheral edge 56. A removable strip 58 is provided which exposes a binding ~lot 60, at which the binder can be po~itioned~
Side protrusions 62 and 64 for cooperation with the paper guid~ caliper arms are also molded into ~he cartridge. Sev~ral indicator padst such as 65, 66, 67 and 68, are provided on the peripheral edg~ o~ the cartridge adjacent the front ~or identifying the types of 20~8~

binders carried in the cartridge. A detailed descrip-tion of the cartridge will be found in U.S. patent application Serial No. 481,857 entitled "Cartridge System for Tool Insertion Type Binding Machine", filed February 20, 1990.
Also shown schematically in Fig. 4 are contact members 65a, 66a, 67a and 68a which electrically contact the indicator pads 65, 6~, 67 and 6$ to detect an encoding representativ~ of the characteristics of the cartridge and the binders therein, for example, the ~ize of the binders, etc. Sensors 86, 88, 90 and 92 are provided for each contact member 66a, 67a, 68a and 69a, the sensors being connected to a control circuit ~hown generally at 200. The sensors 86-92 sense whether the corresponding indicator pad is an open circuit or a short circuit. The combination of the sensor outputs is an encoding of the cartridge and binder character:istics.
The number of indicator pads and sensors depend~ upon the maximum number o~ di~rent charact~ristics desired to be sensed. In the present device, ~our indicator pads are provided. It is also contemplatPd to provide other sensing i~dicating means than those shown. For example, spring biased pin~ connected to electrical contacts which sen~e the presence or absence of holes in the cartridge may be provided. Also optical sensors which sensP the presence of holes may be used.
The Bindin~ Apparatus - Cartri~g~ QEr Referring to Figs. 6 and 8, it is seen that the cartridge, such as 42, is supported on an angle support plate 84 which is positioned at an angle alpha (~) to horizontal, which angle is about 5. The support plate ~4 extends ~rom the operator side o~ the machine ~o the 2~317 back side of ~he machine. Associated with the machine and the support plate ~re a pluraliky of sensors such as 86 in Fig. ~ and ~6, 88, 90, and 92 in Fig. 6, each of which engage a conductive pad on the cartridge to sense the diameter, color, and information of that type from the cartridge~ When the cartridge is in the home position, the interlock system or ~olenoid 93 and plunger 94 engages the cartridge 42 and the plunger is inserted into the cartridge, thereby indicating that the cartxidge is in position. The plunger locks the cartridge in position and acts as a sensor relative to its presence.
Paper Guide In the operative position, the binding slot 60 is positioned at the binding position at the bottom of the paper guide 22. The paper guide ~ generally includes two stationary plates 96 and 9~. A paper thickness caliper system 99 i6 pivotally mounted to the rear plate and has two L-shaped arms, such as lOnl to con~rol the thickness o~ paper in the guide, and lower arms, such as 101, to be engaged by the cartridge protrusions such as 62 and 64. The caliper system is spring biased to a closed position by a tor5ion bar and spring system 102.
The caliper system also ejects cartridge via spring force when solenoid 92 is released. The plate 98 includes elongated, generally vertically-extending rib~-like springs~ such as 103, that engage ~hé calipers and the paper and control thickness of the paper to be accepted and also permit a bound booklet to be withdrawn ~rom the paper guide.
The front and back plates define an entry throat 104 and an exit throat 106 that cooperate in guiding paper through the paper guide. The paper guide is tilted ~8817 with respect to the horizorltal at an angle beta (~ In this case ~ is approximately 82. A sensor, such as 108, is provided for determining whether a binder in a cartridge is in the binding position. Another sensor 109 detects presence of paper in the entry/exi~ throat.
Tool Insertion and Retraction System Once thP binder cartridge is in position and paper is to be delivered, it is essential to select an opening tool and insert the same through the binder. One type o~ system is best seen in Figs. 6 and 7. The tool insertion and retraction sy~tem 110 includes a rotatable drum 112 that houses four separate insertion tools 114, 116, 118 and 120. An appropriate tool is selected by microprocessor control and inserted into the nip of ths drive and idler rollers 122 and 12~. These rollers are connected by a drive belt 126 to ~he remote drive 128 and idler 129. It i5 noted that the ~irst se~ of drive and idler wheels 122 and 124 is on one side of the binder apparatus and the other 128 and 129 is on the other ~ide.
The drive and idler rollers are driven by the gear 125a and drive motor 125b.
Briefly, the drum 112 is rotated, a tool, such as tool 118, engages the nip of khe first drive rollers 122 and 124 and is urged through a binder 30 as it is withdrawn from the drum. That tool then extends to and engages the second drive rollers 128 and 129. Tn this way the binder 30 i~ spread open and the fingers and spine separated so as to be in position to receive a stack of paper. In order to close the binder 30, the tool i5 moved in exactly the opposite direction. It is essential that the operation o~ the tool drum be understood in detail.

2~817 In Fiys. 5, 6 and 7, it can be seen that the tool drum is rotated by a gear assembly 132. The gear assembly includes a motor 136 that drives a worm 137.
That gear i~ turn drives a worm gear 138. Gear 138 has a shaft 139, which connects to the cartridge drum 111. The worm gear prevents any backlash or release of tolerance on the casing or movement of the casing.
The drum casing 112 rotates in a clockwise direction so that the tail on each of the insertion tools 114, 116, 118 and 120 pass the nip as is shown. When the appropriate size of the tool, as determined by the control means through the sensors 86-92, passes the nip, then the drum casing is reverse rotated so as to pus~ the tip of the insertion tool into the drive roll r nip. The positioning and operatio~ of the drum casing is ccntrolled by a microprocessor and sensox 141~ The insertion tool, such as tool 11~, has a lead ~ront end 118a which has a length a little bit longer than the binder 30, and once f~d throuyh the binder 30 and to the take-up rollers 128 and 129, the wider portion ~ tha insertion tool 119 is pulled through the binder to fully open the binder. In this way th~ corxect size insertio~
tool is determined and usedO
A sensor 130 is provided for detecting the presence of an insertion tool in the nip, The illustrated sensor 130 is an optical receiver and arranged so that the insertion tools interrupt the light beam, which may be an infrared beam, when the insertion tool is in position in the binder. Onc~ the tip of tha insartion tool is detected, the clamping system as dascribed hereinafter is activated. The sensor 130 can also detect a slot in the insertion tool which represent~

20~17 the end of the tool or its travel. A spring-loaded rod 131 pushes the insertion tool rearwardly so as to keep the tool in the correct path.
The Clampin~ System In addition, the machine includes a clamping system 133 for positioning, guiding and feeding of the binder and receipt of the paper in the event of certain conditions. Generally speaking, the clamping system includes a plate or clamp 150 that is positioned above and on top of the cartridge 42. The plate as seen in Fig. 6 includes a plurality of fingers such as 152, 154 and 156. A drive mechanism which includes a pair of spaced spur gears, such as 158 and 160, is provided to rotate in the rack-like slots, such as 162 and lS4, in the plate so as to advance the plate to a position where it engages the top sur~ace of the binder positioned just before the binding position and under microprocessor control the fingers can receive paper which is deposited thereon. The drive includes motor 165a that rotat~s gear ~0 16~b that communicates with a spur gear such as 15~. It is to be noted that the operation of the driv~ for the clamping plate is related to the sensors or kabs on the cartridge as well as the positioning o~ the tool and the nip. Very briefly what oc~urs is the plate 150 i~
2s advanced toward th~ binder position slot, can engage the binder ~nd, if appropriate, can engage the paper. In some cases it will withdraw to clamp the paper thereon so as to grasp the paper and assure alignm nt o~ the binder fingers with the cartridge.
In general, the plate and binder fingers are advanced to guide all fingers or actuators to insertion and retraction positions only in situatisns where the binder is o~ a relatively ~mall diameter such as one-fourth inch and three-eighth inch in diameter. In that case the paper falls and engages the insertion tool directly as shown in Fig. 8. However in other situa-tions such a~ where the binder is of a larger diameter,such as one-half inch and five-eighth inch, the plate actually extend between the binder fingers so as to receive paper falling thereon and then retracts to tighten and grasp the paper ~nd in effect clamp the paper for binding. At the end of binding there is a small jogging motion which occurs.
The clamp or plate 150 can be thought of as moving to a feed posi~ion, a load position, where the paper falls on the clamp 150 to a clamping position where there is a retraction of the clamp so as to tighten the paper, a jog and remove position so as to loosen the paper and remove the clamp and home position.
Referring to ~igs. 10-13, it is seen that the clamping plate, such as 150, advances to engage the top of a binder, such as 166. Where the binder is of a larye diameter, the clamp continues so that the paper, ~uch as 16B, which is fed into the paper guide falls on the clamp rather than on the insertion tool such as 170~ The fingers clamp the paper between the upstanding end leg of each ~inger and the rear plate o~ the paper guide 22.
This aligns the apertures in the paper, such as 172, ~or receipt of fingers on the binder 166. When the binders are aligned and the papers aligned, the tool 170 is withdrawn~ as seen in Fig. 13/ and the fingers snap through the binder as shown in Fig. 13. Therea~ter, the book can be withdrawn and at the same time the clamp moves to the rearward position.

2 ~ 7 The foregoing operation is controlled in the following way and by the following apparatus:
Figs. 14-17 show a flow chart ~or the op~ration and control of the automatic binding apparatus of the present invention. The operation of the apparatus is initiated in Fig~ 14 by turning on the power switch 26 at step 202, whereupon the control circuit for the present device immediately retracts any insertion tool which may be in an extended position, at step 204. Since it is desired that the tool retraction occur within a predetermined maximum time, such as 3 seconds, the timer ~tep ~n6 determines whether a predetermined time interval t1 has expired. If less than the predetermined interwal t1 has expired, a check is made at step 208 to determine whether the tool is in the home position. If not, a branch of the flow chart loops back to continue timing the time interval. If the predetermined time interval t expires, then a branch from block 206 triggers blinking of a fault lamp in block 210.
Assuming fault free operation, the apparatus senses the tool in khe homP position before the expira-tion of the predetermined time interval tl and moves to block 212 to sense whether paper is in the throat of the device. If paper is sensed in the throat of the device, a blinking fault lamp is turned on at block 214 and the operating circuit continuas to check for paper removal at block 216 until the paper has been removed, which causes the ~ault lamp to be turned o~f at block 218.
I~ no paper wa~ found in the throat or if the paper found in the throat has been removed, the control moves the clamp to a home position at block 220~ This likewise is timed over a predetermined time interval t2, - 12 ~

2~817 such as two seconds at block 222 to determine whether the time interval has expired. If the time interval t2 expires, the fault lamp is blinXed in hlock 224, but if the sensor determines that ~he clamp is in the home position, in blsck 226, before the expiration of the time interval t2, then a sequence of steps 228, 230, 232 and 234 which are substantially equal t~ the steps 212, 214, 216 and 218, respectively, are carried out to determine whether paper is in the throat~
Following these steps, a determinati~n is made as to whether a binder cartridge is in place, at step 236 as shown in Fig. 15. I~ not, the cartridge lamp is blinked at step 238 until the cartridge is in place. Once a cartridge is sensed, the cartridge lamp is turned off at step 240 and the tool drum is rotated to select the appr~priate tool size for the cartridge at step 242~ A
maximum time t~ o~, for example, five seconds is allowed for the selection of the appropriately sized tool, as determined by step 244. As before, if the time i~terval t3 expires then a fault lamp is blinked at step 246; on the other hand, if the tool i5 selected within the time interval t3, this is sensed at block 2~8 and the control process again checks to determine whether there is paper in the throat of the device, at steps 250~ 252, 254 and After determining that no.paper is in the throat, the step 258 determines whether the cartridge switch is activated. If the ~artridge switch has been activated, there are no more binders in the cartridge and the cartridge is ejected at step 260, after which the :
cartri~ge lamp is blinked at StPp 238. If the rartridge switch is not activated, indicating the presenee of at - 13 - ;

least one binder in the cartridge, then the ~ind cycle is initiated at step 262 and the clamp is moved to the feed position at step 264.
Continuing in Fig. 16, a time interval t4, for example two seconds, is measured at block 266 to determine if the clamp reaches the feed position, in block 268. If not, the fault lamp is blinked at block 270. Once the clamp is in the feed position, the binder is opened at block 272. The time interval t5 of, for example, thr~e seconds in block 274 which is permitted for the opening of the binder, which is checked at block 276. If the binder lS not open after the time t5, the ~ control blinks the fault lamp at block 278. Once the binder is opened, the clamp is moved to the load posikion at block 280, a time interval t6 f, for ~xample, one second being allowed for opening o~ the clamp via blocks 282, 284 and 286.
Once the binder has been opened and the clamp moved to the load position, a ready lamp is turned on and a timer, which is in this embodiment a ~ive minute timer, is set at step 288. The throat paper sensor i5 checked at step 290, and if paper is in the throat, a determination is made in step 292 as to whether the bind switch is activated. On the other hand, if no paper i~
sensed in the throat in step 290, a check of the timer is made at step 294 and if the timer has counted down to zero the control is returned via connector D to the beginning of the control sequence in Fig. ~4. I~ the timer has not reached zero, the cartridge switch is checked in step 2g6. Activation o~ the cartridge switch transfers control through connector C to the portion of the flow chart shown in Fig. 17. Lack of activation of 2~81~

the cartridge switch trans~ers control back to step 290.
If the control process reaches step 292 and the bind switch is not activated, a check is made of the five minute timer to see if it has reached zero at step 29g.
If the timer has reached zero, then the connector D
transfers control of the process back to the beginning in Fig. 14. If the timer has no~ reached zero, then control is transferred back in a loop to block 290.
Referring once again back to block 292, if the bind switch is activated, the connector B transfers control to Fig. 17 wherein blocX 300 indicates movement o~ the clamp to the clamp position~ As with many of the other actions taken in this process, a time interval t7 which is, for example, one second? is measured in block 302 and if the time t7 expires before the clamp is in the clamp position then the fault lamp is blinked in block 304. If, on the other hand, the clamp reaches the clamp position before the expiration of the time interval, this is sen~ed in block 306 and the tool is retracted to the home position in block 308. The retraction o~ the tool i~ given a maximum time interval t8 of, for example 9 three seconds in block 310 after which the ~ault lamp is blinkad in block 312 if the tim~ interval has expired.
If the tool reaches the home. position before the expiration of th~ time interv~l t8, this is ~ensed in block 314 and then block 316 c~uses the ready lamp to be ~urned off and the timer to be reset. Block 318 turns on the "remove book" lamp, indicating that the book has bePn bound and is ready for removal. A sensor is checked in block 320 to determine if the book has been removed and once the book is removed, the "rsmove boo~" lamp is turned off in block 322. The clamp is then moved to a 2~8~7 home position in block 32~ and, as before, a time interval tg of, for example, two seconds is permitted in block 326 for the clamp to move to the home position before the Pault lamp is blinked in block 328. The home position of the clamp is sensed in block 330, after which the cartridge switch is checked ~o determine whe~her it is empty or not at block 332. Activation of the cartridge switch causes ejection of the cartridge at block 334, while lack of activation transfers process contrvl at connector F to the portion of the process shown at the bott~m of Fig. 15.
Fig. 18 shows a circuit for carrying out the control process shown in Figs. 14-17. In particular, a microprocessor 350 is programmed with the necessary software or firmware to follow the control process. In detail, an input line 352 to the microprocessor in~orms the microprocessor of the ondition of the power switch, whether it is on or vff, while input lines 35~ and 356 transmit signals from the cartridge switch and the cartridye sensor, respectively. A clamp position sensor signal is transmitted over the input line 358.
Additional input to the microprocessor is ~ed through a first input buffer 360 and includes, for example, a line 362 for the punch switch, a line 364 for the bind switch, a line 366 ~or the tool home sensor, an input line 368 for the paper thro~t sensor, a line 369 for start/reset, and lines 370 and 372 for punch sensors. Additional input lines may be provided as needed. A second input buffer 374 receives a four bit cartridge code over the lines 376, 378, 380 and 382, a punch paper alignment sensor signal from lines 334 and 386, a clamp home sensor signal on line 388 and, finally, a ~ool mechanism sensor 2~8~7 on line 390. The input signals from these input bu~rs 360 and 374 are fed through a data bus 392 to the microprocessor 350O
To enable the microprocessor 350 to control the various operators and light the various indicators, a control and select bus 394 connects the microprocessor to a chip selector 396 which has outputs connected to the enable inputs of the input buffer 360, the input buffer 374, an output latch 398 and an output latch 400. When enabled by the chip selector 396, the buffers and latches control the flow of data on the data bus 392. The microprocessor based control circuit has an interface with various electromechanical devices through a bank of optical couplers 402. The microprocessor 350 through the data bus 392 and the output latch 398, as well as one of the optical couplers 402, controls a forward drive 404 o~
a punch motor 406 as well as the reverse drive 408 thereof. Also controlled is the brake drive 410 which operates the brake 412 ~or the punch. Not only does the microprocessor 350 control the operat.ion of the punch but also the operation of the insertion tools 414 through a forward and reverse drive 416, the paper clamp 418 through a forward and reverse drive 420, the tool drum 422 through a forward and reverse drive 424, and a - 25 cartridge solenoid 426 through a solenoid drive 428. The tool drum and the cartridge solenoid are controlled directly by the microprocessor in the illustrated embodi m~nt, rather than through th~ output latches 398.
The output latches 400, on the other hand, are used to control indicators, In particular, a driver 430 at the output o~ the latche~ 400 drive a faulk lamp 432, a check cartridge lamp 434, a rem~ve book lamp 436, and a 2~8~7 ready lamp 438. A start/reset lamp 439 is also provided.
Each of the indicator lamps 432 439 is connected by a resistor to a positive supply. In the illustration of Fig. 18, a power supply 440 is provided for the control circuitry while a separate power supply 442 is provided for the mechanical operators.
Although the invention has been described with respect to preferred embodiments, it is not to be so limited as changes and modifications can be made which are within the full intended scope of the invention as defined by the appended claims.
