- rollers 32, 34, 36 and 38 In the feed section which is on the right of machine as seen from the front is a spool frame 30 on which are four rollers 32, 34, 36 and 38 (not shown). Rollers 36 and 34 have a rubber roller 35 of coarse textured rubber between them (see Fig. 9). The rubber roller acts to strip a paper web 42 from between layers of binding wire strip on the spool 40. The web 42 feeds over the rubber roller under the spool and is ejected-----------down a chute 44 (see Fig..9) to the rear of the machine.
- Rollers 36 and 34 are driven by a belt 46 through a gear box 48 and by a motor 50.

- Pitch will be referred to as 2:1, 3:1 and 4:1 hereafter,'omitting the linear units.
- Diameter will be referred to hereafter using the above fractions of an inch without the units.
- this strip shown at 52 comes off the spool onto a pivotally mounted horizontal tray 54 pivoted on to the end cover 302: after passing over the tray the slack in the strip is controlled by proximity switches 300 and 301 which sense the angle deflection of the wire feed tray 54.
- the strip After passing over the tray 54 the strip is then fed to one of two feed sprocket wheels 80, 82 one being for 2:1 and 4:1 pitch and the other for 3:1 pitch (see Fig. 3) the sprocket wheels 80 or 82 are aligned with a main feed chain shown in Fig. 3 as a broken line 84 extending from the feed section 22 through binding section 24 to mechanism section 26.

- the brackets are then pushed upwards engaging wheel 80 with the strip 120 and the plunger 104 is re-engaged to hold brackets up.
- a "V" shaped guide 122 Located above the sprocket 82 (see Fig. 4) or alternatively above sprocket 80 whichever is aligned with chain 84 is a "V" shaped guide 122 whose sloping sides 124 and 126 act to guide the blunts 15 and points 12 of the strip 120 respectively, the points being to the rear of the machine.
- a central guide fillet 128 at the apex of sides 124 and 126 acts to press the connecting portions 10 of the strip (see Figs. 5 and 6) onto wheels 80, 82 and thereafter the strip onto the main drive chain 84.
- the guide 122 can also be formed as in our copending-British Patent Application No. 8111808 filed 14th April 1981, the contents of which are incorporated herein by reference.

- Running parallel to chain 84 is a skip conveyor chain 140 similarly provided with notched chain inserts whose upper conveying surface is level with the upper conveying surface of chain 84.
- Chain 140 extends across section 24 and between an idling sprocket wheell42 (Fig. 1) and a drive sprocket wheel 144 (Fig. 14) driven through a belt 145 by a single 1.8 0 stepper motor 146 of smaller capacity than motor 134 in unit 132.
- Motor 146 is of a smaller capacity because chain 140 is shorter than chain 84.
- the skip conveyor function will be described hereafter.
- Adjacent frame 6 is a stepper motor control module (not shown) which controls the predetermined indexing of the stepper motors according to a programme selected on a control panel mounted on the right hand end as seen from the rear (not shown).
- the cutter and the transfer of wire from chain 84 to chain 140 by a pusher mechanism forming part of a translating means are controlled entirely by the stepper motor control module.
- the pusher mechanism comprising a pusher bar 150 (see Figs. 1 and 7) mounted adjustably on a block 152, the adjustment being relative the block and from front to rear. Adjustment between block and bar is by means of a slot 151 in block 152, lock' knobs 154 and fine adjustment screws 310 one each of which is shown in F ig. 7A.

- These pneumatic cylinders have 3 magnetic reed switches to enable the pusher assembly to be moved between three positions: namely, a first position D as shown in Fig. 7 with pusher assembly retracted, a second position E, with pusher assembly moved halfway forward (used when using skip binding facility) and a third position F when pusher assembly is fully forward.
- a first position D as shown in Fig. 7 with pusher assembly retracted
- a second position E with pusher assembly moved halfway forward (used when using skip binding facility)
- a third position F when pusher assembly is fully forward.
- the pusher bar rests against binding elements 160 on the main chain.
- the pusher bar moves the element 160 onto the skip chain.
- the pusher bar moves the element 160 to a transfer bar 180.

- the member 182 however holds the elements 160 by the resilience of its material suitably high density polythene.
- the member 182 must be changed for each pitch and diameter used in the machine since the lateral distance between teeth 185 is relative the pitch and the book stop higher teeth 185 have a height depended on element diameter.
- Pivotal control of the-transfer bar 180 is by means of a pneumatic actuator (not shown) connected to shaft 182.
- the pusher bar mechanism and transfer bar arrangement form parts of translating means for translating the elements either singly or in plurality from the feed device conveyor to the closing means of which the closing jaws are a part.

- Top jaw or tool 188 is mounted in a top tool holder 192 and can be removed therefrom by unscrewing retaining screws 194 (see Fig. 10).
- the lower surface of jaw 188 is curved to the diameter of the element and projections 198 locating between the wire points extend from the curved surface a distance corresponding to the wire gauge.
- the separation of projections 196 is dependent on wire pitch, for this reason if pitch or diameter of wire is to be changed the top tool must be changed.
- the bottom tool 190 is mounted in a bottom tool holder 198 to which it is retained by further retaining screws 194.
- This tool also has a curve forming surface to the diameter of the element and projections 196 locating between the wire points_extend from the curved surface a distance corresponding to the wire gauge.
- the separations of projections 196 is dependent on wire pitch, for this reason if pitch or diameter of wire is to be changed, the bottom tool must also be changed.

- the top tool 188 is movable by means of a cylinder 228 through a pair of adjustable turnbuckles 216 attached to top tool holder 192 and to a rocker arm 218 on one side and an arm 222 on the other side (see Fig. 10).
- Rocker arm 218 and arm 222 are linked by a rod 224, a piston rod 226 connecting arm 218 to a piston (not shown) in cylinder 228.
- Cylinder 228 is pneumatically operated and has a magnetized piston (not shown).
- Reed switches 230 and 232 are mounted on screws 234 and 236 each driven by a respective motor 238 and 240.
- the stroke of the piston is adjusted between 3 positions, that is firstly piston down-upper tool fully up, secondly upper tool partially down - binding element held between jaws, and thirdly upper tool down - jaws closed.
- the second and third positions are those which have to be adjusted for different wire diameter and these positions are controlled by location of the reed switches 230 and 232 respectively relative to the cylinder.
- the motors 238 and 240 are switched on and the reed switches moved to a new predetermined position as more particularly described in coterminous Patent Application No. (claiming priority from British Patent Application No. 8214894 of 21st May 1982) incorporated herein by reference.

Abstract
A wire binding machine for accepting and closing wire-0-type binding wire (10) to bind a stack (200) of sheets together in which the machine is enabled to accept a plurality of differentiy pitched and diametered wire sizes by means of an adaptable input feed means (80, 82), feed conveyor (84), translating means (150, 180) and closing means (192, 198)
Description
- The present invention relates to wire binding machines for closing wire binding elements to bind bundles of sheets. It is particularly applicable to those machines which use binding which are each formed from a length of metal wire bent to form a series of curved hairpin-shaped prongs on which sheets are impaled and which are brought to ring shape by pressing their closed ends or "points" into the vicinity of their open ends or "roots". Such binding elements will be referred to herein as "Wire-0" (Registered Trade Mark) binding elements.
- Binding machines of the kind described above will be referred to herein as "machines of the kind set forth".
- "Wire-0" binding elements as shown in Figures 5 and 6 of the present application are supplied to machines of the kind set forth from spools in the form of a long continuous "strip" in a so called "open" condition, the end view being as shown in Figure 6. The "strip" is then cut into lengths referred to as "elements" and the "points" shown at 12 in Fig. 5 are formed by a closing device of the machine into the "closed"position.so that the end view is approximately circular of a predetermined "diameter" with the "points" formed into the "roots" shown at 14. Wire portions between the roots as shown at 15 will be referred to as "blunts". The distance between the "points" will be referred to as the "pitch" of the strips. The bundles of sheets to be bound whether in substantially book pad or like form or variations thereof will be generally referred to as "bundles" or stacks.
- The guidance of "strips" in machines of the kind set forth has to be carefully controlled and therefore it has been generally the case that such machines are designed for a particular "pitch" and "diameter" of wire "strip". Due to the increasing use of "Wire-0" binding elements, binders have found it necessary to increasingly vary the "pitch" and "diameter" which has not been possible with known such machines.
- A machine of the kind set forth according to the present invention comprises input feed means arranged to accept binding strip, a feed device arranged to feed the "strip" from the input feed means, a cutting means enabled to cut the "strip" into binding elements of predetermined length and fed by the feed device, a closing means at a closing station arrange to be fed with the elements, means for translating the elements either singly or in plurality from the feed device to the closing means and a bundle feed table for supporting a. bundle at the closing station wherein the input feed means, feed device, translating means and closing means are adapted to accept binding "strip" and binding "elements" of predetermined and variable pitch and/or predetermined and variable diameter.
- Preferably the input means is arranged to be driven at the same linear speed as the feed device and may be provided with strip engaging toothed feed wheels, each having a tooth pitch differing one from the other, means being provided to shift a required wheel in alignment with the feed device. In one preferred embodiment only two wheels are provided, the differing toothed pitches enabling engagement with a wide range of differently pitched strip.
- Preferably the feed device comprises a main conveyor having a plurality of strip engaging members. The conveyor is preferably a chain with the strip engaging members formed as notched teeth located between the chain links. The conveyor preferably extends between the input feed means to and beyond the translating means. Allowance for a wide range of differently pitched strip is achieved by the strip engaging with different surfaces of the notched teeth. Allowance for a wide range of differently diametered strip is achieved by means of a wedge shaped guide adjacent and parallel the conveyor, the points and blunts of the strip being guided by either side of the guide surfaces.
- In order to allow for calendar binding a skip conveyor running parallel to the main conveyor may be provided at the closing station, the translating means being arranged to translate a first binding element from the main conveyor to the skip conveyor and a second binding element from the main conveyor to the skip conveyor with a longitudinal gap between the elements.
- Preferably the translating means is provided with adjustment for different diametered elements. The adjustment may comprise stroke adjustment and/or an adjustable guide adjacent and parallel the main conveyor, the guide acting approximately on the points and blunts of the elements to locate each element on the main conveyor, the adjustable guide being adjustable for separation distance from the main conveyor.
- Preferably the closing means is adjustable for relative stroke to allow for different element diameters, closing means comprising a bottom adjustable height tool holder and a top tool holder; the tool holders may have replaceable forming tools to allow for different diameters and/or pitches of the elements.
- Preferably the cutting tool is adjustable in a
direction 26° to the vertical to allow for variations in diameter of the strip. Variations in pitch of the strip may be allowed for by adjustment in the position where the feed device stops. The cutting tool is preferably arranged to cut the "blunts" of the strip and one jaw is located above the main conveyor whilst the other jaw is located to the front of that conveyor. - Preferably the bundle feed table is adjustable for height relative the closed position of the closing means so that a perforated bundle on the table locates with the perforations aligned with the points on the binding element when this is held by the transfer bar between upper and lower closing jaws of the closing means.

Theweb 42 feeds over the rubber roller under the spool and is ejected-----------down a chute 44 (see Fig..9) to the rear of the machine. -
Rollers belt 46 through agear box 48 and by amotor 50. The motor drive is controlled via a clutch device so as to rotate the spool when receiving a signal from one of the proximity switches (300 and 301). The other switches the machine off if the wire tangles on the spool or becomes jammed in the main feed. -
- The diameter has already been. referred to as the "closed" diameter and the pitch is the distance between adjacent "points" 12 (see Figs. 5 and 6). Pitch will be referred to as 2:1, 3:1 and 4:1 hereafter,'omitting the linear units. Diameter will be referred to hereafter using the above fractions of an inch without the units.
- When using a selected diameter Wire-0 strip, this strip shown at 52 comes off the spool onto a pivotally mounted
horizontal tray 54 pivoted on to the end cover 302: after passing over the tray the slack in the strip is controlled byproximity switches wire feed tray 54. - In the event of failure of supply of Wire-O from the spool the feed tray will deflect to its maximum limit triggering the appropriate proximity sensor resulting in the machine being switched off automatically. !
- After passing over the
tray 54 the strip is then fed to one of twofeed sprocket wheels sprocket wheels broken line 84 extending from thefeed section 22 through bindingsection 24 tomechanism section 26. -

The brackets are then pushed upwards engagingwheel 80 with thestrip 120 and theplunger 104 is re-engaged to hold brackets up. - It will be appreciated that the drive arrangements to the
wheels chain 84 andwheels - Located above the sprocket 82 (see Fig. 4) or alternatively above
sprocket 80 whichever is aligned withchain 84 is a "V" shapedguide 122 whose slopingsides blunts 15 and points 12 of thestrip 120 respectively, the points being to the rear of the machine. Acentral guide fillet 128 at the apex ofsides portions 10 of the strip (see Figs. 5 and 6) ontowheels main drive chain 84. Theguide 122 can also be formed as in our copending-British Patent Application No. 8111808 filed 14th April 1981, the contents of which are incorporated herein by reference. - The
drive chain 84 forming a part of a feed device feedsstrip 120 from the input feed means to a cutting means 130 not shown in detail but located in theframe 6 betweensections drive chain 84 is a link chain forming a main conveyor which has a plurality of strip engaging members formed as plastics cruciform notched chain inserts which are shown in detail with the chain in our co-pending British Patent Application No. 8111808 filed 14th April 1981. The form of the notches allows for differently pitched strip to be firmly engaged whatever the pitch. - The cutting means 130 is a knife and anvil, the knife being adjustable from top of the machine to ensure that it chops the strip on a blunt portion, adjustment being necessary when the diameter is changed.
- The
chain 84 extends throughsection 24 to achain drive unit 132 mounted insection 26 onframe 8, theunit 132 includes a high capacity main chain drive 1.8°stepper motor 134 driving through a belt 135 a drive sprocket wheel 136 (see Fig. 14). - Running parallel to
chain 84 is askip conveyor chain 140 similarly provided with notched chain inserts whose upper conveying surface is level with the upper conveying surface ofchain 84.Chain 140 extends acrosssection 24 and between an idling sprocket wheell42 (Fig. 1) and a drive sprocket wheel 144 (Fig. 14) driven through abelt 145 by a single 1.80stepper motor 146 of smaller capacity thanmotor 134 inunit 132.Motor 146 is of a smaller capacity becausechain 140 is shorter thanchain 84. The skip conveyor function will be described hereafter. -
Adjacent frame 6 is a stepper motor control module (not shown) which controls the predetermined indexing of the stepper motors according to a programme selected on a control panel mounted on the right hand end as seen from the rear (not shown). The cutter and the transfer of wire fromchain 84 tochain 140 by a pusher mechanism forming part of a translating means are controlled entirely by the stepper motor control module. - To the rear of the main chain in
section 24 and extending from side to side of the section is the pusher mechanism comprising a pusher bar 150 (see Figs. 1 and 7) mounted adjustably on ablock 152, the adjustment being relative the block and from front to rear. Adjustment between block and bar is by means of a slot 151 inblock 152, lock'knobs 154 and fine adjustment screws 310 one each of which is shown in Fig. 7A. Thebar 150 has anelement pushing surface 156 which engages against the points side of a binding element one of which is shown at 160 which has been cut fromstrip 120. Mounted onpusher bar 150 is a packer member 156 (changed for each wire diameter) from which extends an acrylicadjustable guide plate 166 held on byhandwheels 168 so that the guide is just clear of the top of anelement 160 as it sits on thechain 84. Depending on the wire diameter thisguide 166 is adjusted up or downrelative chain 84 by providing a packer 156-of a differing height. - The
pusher bar 150 and mountingblock 152 are mounted on piston mountings of a pair of rodlessmagnetic cylinders 174, one at each end coupled toframe 6 andframe 8. These pneumatic cylinders have 3 magnetic reed switches to enable the pusher assembly to be moved between three positions: namely, a first position D as shown in Fig. 7 with pusher assembly retracted, a second position E, with pusher assembly moved halfway forward (used when using skip binding facility) and a third position F when pusher assembly is fully forward. In the first position the pusher bar rests againstbinding elements 160 on the main chain. In the second position the pusher bar moves theelement 160 onto the skip chain. In the third position the pusher bar moves theelement 160 to atransfer bar 180. -
Transfer bar 180 is pivotally mounted on ashaft 181 and movable from the horizontal position shown in Fig. 7 to an upper vertical position where it can hold anelement 160 between upper andlower closing jaws transfer bar 180 relative its horizontal position is aplastics carrier member 182 retained onto thebar 180 by a dovetail recess in the bar and adovetail locating plate 184. Themember 182 is formed with groups of about fiveteeth 185 extending up from thebar 180 to about the same level as the top of the chain notched inserts and between each group ahigher tooth 186 about twice the height ofgroup teeth 185 is provided. Thesehigher teeth 185 act as book stops in a similar way to the book stops described in our copending British Patent Application No. 8111828 filed 14th April 1981. Themember 182 however holds theelements 160 by the resilience of its material suitably high density polythene. Themember 182 must be changed for each pitch and diameter used in the machine since the lateral distance betweenteeth 185 is relative the pitch and the book stophigher teeth 185 have a height depended on element diameter. - Pivotal control of the-
transfer bar 180 is by means of a pneumatic actuator (not shown) connected toshaft 182. The pusher bar mechanism and transfer bar arrangement form parts of translating means for translating the elements either singly or in plurality from the feed device conveyor to the closing means of which the closing jaws are a part. - The closing
jaws perforations 199 in abundle 200 on a feed table 210, only thetop jaw 188 moving. Top jaw ortool 188 is mounted in atop tool holder 192 and can be removed therefrom by unscrewing retaining screws 194 (see Fig. 10). The lower surface ofjaw 188 is curved to the diameter of the element andprojections 198 locating between the wire points extend from the curved surface a distance corresponding to the wire gauge. The separation ofprojections 196 is dependent on wire pitch, for this reason if pitch or diameter of wire is to be changed the top tool must be changed. - The
bottom tool 190 is mounted in abottom tool holder 198 to which it is retained by further retainingscrews 194. This tool also has a curve forming surface to the diameter of the element andprojections 196 locating between the wire points_extend from the curved surface a distance corresponding to the wire gauge. The separations ofprojections 196 is dependent on wire pitch, for this reason if pitch or diameter of wire is to be changed, the bottom tool must also be changed. -
Bottom tool 190 is adjustable for height by means of a pair of screw jacks drivable viaworm wheels 204 andworms 206 from amotor 208 controlled from the control panel. - The
top tool 188 is movable by means of acylinder 228 through a pair ofadjustable turnbuckles 216 attached totop tool holder 192 and to arocker arm 218 on one side and an arm 222 on the other side (see Fig. 10).Rocker arm 218 and arm 222 are linked by arod 224, apiston rod 226 connectingarm 218 to a piston (not shown) incylinder 228.Cylinder 228 is pneumatically operated and has a magnetized piston (not shown). Reed switches 230 and 232 are mounted on screws 234 and 236 each driven by arespective motor motors
(claiming priority from British Patent Application No. 8214894 of 21st May 1982) incorporated herein by reference. - In order to ensure the bundle to be bound is in the correct position for binding relative a particular .diameter of binding element, the table 210 is adjustable for height. The table has a projecting
rear lip 250 the rear upper edge of which must be level with the blunt portions of the wire elements. The gap betweenlip 250 andbottom tool 190 is taken up by a filler platp 315 (see Fig. 7). - To adjust the table a simple elevating device is shown in Figs. 11 and 12 comprising a
knob 252 accessible from the side of the machine, a pair ofcams 254 mounted onshaft 256 supporting twobuttons 311 fixed to the underside of the table. The front of the table has two brackets 312 with half round slots supported on two pivot bars 262 attached toframes buttons 311 are always in contact withcams 254. By turninghandwheel 252 clockwise the table can be raised to required height. The handwheel can be rotated clockwise only. This is achieved by a freewheel assembly 314 mounted oncam shaft 256 and attached toframe 8. Thetable assembly - On top of the table 210 is a
lay gauge 270 with an adjustable guide fence 272, the gauge being locatable in any one of a number of positions on the table. The gauge is used for aligning bundles. Also on the top of the table is a pneumatic detector 274 which detects the presence or lack of presence of a bundle on the table and with a suitable interlock circuit prevents a further element being presented to the closing jaws before the bound bundle or book is withdrawn from the table. The pneumatic detector can be replaced by an electronic or other suitable detector. - The cutting means 130 comprises a
cylinder 501 mounted to ablock 502. The block has a pair ofangled slots pins adjustment knob 512 with an externally threadedstem 518 screws in and out of internally threadedcollar 520 is mounted to block 514;screws secure block 514 toframe 6. The end ofstem 518 is held rotatably to block 502 bypin 522 so that by turningknob 512block 502 can be moved at an angle of 26° to the verticalrelative frame 6. - A
piston rod 524 ofcylinder 501 acts onyoke 528 to move a knife 530 aboutpivot 526 so as to cut thewire 52 on an anvil 532 (the knife 530 andanvil 532 forming cutter jaws). The anvil is located immediately abovefeed conveyor 84 whilst the knife is towards the front of the machine. The knife and anvil together act to cut thewire strip 52 at a 'broad' 15, that is on the side of the strip opposite the 'points' 12. In order to allow for different diameters ofwire 52 the anvil and knife are adjusted along theline 534 by means ofknob 512. The angle of 260 to the vertical which is the inclination ofline 534 has been found to cover all diameters of wire previously. Clearly this angle can be made subject to a slight variation, for example it may be between 200and 30°. - The control interlocks and sequencing arrangements for the machine are obtained by means of latching and de-latching electrical relays, controlled by cascaded electrical limit switches.
- To change the machine from one diameter binding element to another the following adjustments are made:
- (i)
Release knob 154 and adjust pusher bar stroke withscrews 310. - (ii) Adjust guide height with
handwheels 168 and by introducing acorrect size pusher 156. - (iii)
Change tools - (iv) Change
transfer bar member 182. - (v) Reposition
bottom tool holder 140 for correct height by means of a bottom tool up switch or down switch on the control panel. - (vi) Adjust top tool stroke by activating
motors - (vii)
Change spool 40. - (ix) Introduce strip feed lead in the form of
- a dancing loop on
tray 54 and into wire feed switch and onto the main conveyor. (x) Repositioncutter assembly 130 by means ofknob 512. - To change the machine from one pitch of binding element to another the following adjustments are made:
- (i) Change position of
wheels - (ii) Change
top tool 188. - (iii)
Change bottom tool 190. - (iv) Change
transfer bar member 182. - The overall rather than detailed difference between the present machine and prior machines is that the present machine is designed to be easily adaptable to handle a large number of different sizes and pitches of binding wire; furthermore the provision of right to left feed of the binding wire ensures that the points are to the rear of the machine prior to location between the jaws. This ensures that the points are pressed downwards into the bundle so that when bundles are fed front uppermost onto the table the junction between points and roots is at the back of the bundle which is most desirable for a clean binding appearance. Previously bundles had to be placed front downwards on the table. The closing of points downwardly ensures that oversize covers can be bound, the back cover being placed on the front cover and swung to the back after completion of binding. The oversize cover can be oversize on all sides except the binding side, that is on three sides.
- Arrangements for skip binding are described more particularly in copending Application No.
(claiming priority from British Patent Application No. 8214896 filed 21st May 1982) incorporated herein by reference. - Other arrangements for the machine described herein are described more particularly in copending Applications Nos.
(claiming priority from British Patent Applications Nos. 8214893 and 8214894, both filed 21st May 1982) incorporated herein by reference. - For oversize binding a special lay-
gauge 602 shown in Fig. 13 is provided. This has a vertical locating face 606 for locating a pair of oversize covers 608 placed on the loner side ofstack 200. A stop arm 610 comprising aweighting bar 612 andfin 613 is pivotted tobody 604 by pin 616.Fin 613 has its gaugingface 614 engaging withstack 200, which face is parallel to face 606. The distance between the parallel faces 606 and 614 governs the amount of oversize overlap between the covers and stack and this is adjusted by means of a screw 618 which joins with pin 616.
