Description

METHOD AND APPARATUS FOR ROTATION OB BARBA DB3PRBHDBDQK? This invention is related to a bar assembly with detaching finger, for printers and duplicators and more specifically to a bar assembly they are stripper finger for a fusion assembly that allows easy access in areas of paper jam. AjjTePBHTBS DB LA IHVEM IOM In currently commonly used printers and duplicators, a typical photoelectric isolating member is charged to a uniform potential and then exposed to a light image of an original document to be reproduced. The exposure discharges the photoconductive insulating surface in exposed or background areas and creates a latent electrostatic image in the member corresponding to the image areas contained within the original document. Subsequently, the latent electrostatic image on the photoconductive insulating surface becomes visible by revealing the image with organic pigment. Most developing systems employ a developer material comprising both charged carrier particles and charged organic pigment particles that adhere triboelectrically to the carrier particles. During the development the organic pigment particles are attracted from the carrier particles by the charge pattern of the image areas in the insulating area REF: 24750 photosondrush to form a powder image in the photosondrotora area. This image is subsequently transferred to a support surface such as copying paper to which it is permanently affixed. After transfer of the organic pigment image to a supporting surface, the photosondustor insulating member is cleaned of any residual organo pigment that may remain in preparation for the next image-forming system. One of the most conventional approaches to fix the organo pigment image is through the use of heat and pressure when passing the printing substrate which are the unorganized pigment image of an organism pigment through a point of subjection created between a pair of members. of opposing roller, at least one of it is heated and is usually referred to as the fusing roller, and the other is pressed against the fusing roller and is usually referred to as the pressure roller. During this process, the temperature of the organic pigment material is raised to a temperature in the sual; the organic pigment material coalesces and becomes adherent. This heating causes the organic pigment to flow in a certain proportion towards the fibers or pores of the substrate. Subsequently, as the organic pigment material is cooled, the solidification of the organic pigment material causes it to bond to the substrate. Typical of these fusing devices are two roller systems, wherein the fusing roll is coated with a material such as silicone rubber or other low surface energy elastomer. The silicone rubbers that can be used as the surface of the fusion roll include silicones vulcanizable at room temperature, referred to as RTV somo silicones, extrudable or moldable silisone rubbers by injection of liquid, and high temperature vulcanizable silisones referred to as HTV silisones. During the fusing process, and despite the use of low surface energy materials for the fusing roll surface, there is a tendency for the copying substrate to adhere to the fusing roll after passing through the clamping point between the fusing roll and the fusing roll. the pressure roller. When this happens, the adhered print copy substrate does not follow the normal substrate path but instead continues on an arcuate path around the fuser roller, eventually resulting in a paper jam that will require operator involvement to remove the jammed paper before any subsequent print cycle can proceed. This jammed piece of paper can also lead to a damaged fuser roller, a condision that requires that a trained servise replace the roller, which is an expensive procedure. As a result, it has been common practice to use one or more techniques to ensure that the printing substrate detaches from the sorbent fuser roll below the melter subjection point. One of the common approaches has been the use of a stripper finger or a plurality of collapsed stripping fingers in sontaste are the fuser roller, to detach the printed substrate from the fuser roller. Normally, the shape of the fingers, and their positioning and orientation as opposed to the fusing roller are very important for their function, especially in the case of flexible detaching fingers. Still, the use of detaching fingers is insulated, a copy substrate may get stuck in the fuser assembly and when this occurs, the detaching fingers must move away from the jammed paper so that the area of the paper jam is audible for an operator to clear it. . In a sorrentive fusion assembly, detaching fingers are mounted on a pivotable release finger mounting bar, which moves the detaching fingers away from the fusion roller when the top cover of the fusion assembly opens. However, the degree of rotation of the mounting bar is limited and at the end of the complete rotation of the mounting bar, the detaching fingers are still exposed to manipulation by the operator and / or damage during the process of clearing the jammed paper in the path of the paper. Due to the easily deformable nature and some types of detaching fingers and the ability to maintain their intended shape and orientation by design, it is convenient to keep the fingers detached out of the jam-free path by the casual operator in order to minimize their damage potential during release of jamming. The following descriptions may be relevant to various aspects of the present invention. US Patent? No. 4,336,992 Inventor: Szlucha et al., Granted: June 29, 1982 Patent of the U.S.A. No. 4,771,310 Inventor: Leo et al., Granted: September 23, 1988 Some relevant portions of the foregoing descriptions may be briefly summarized as follows: U.S. Pat. No. 4,336,992 illustrates a stripper apparatus for a fuser roller in the form of a flexible finger structure. The detaching fingers contact the surface of the heated fusing roll and are sufficiently flexible such that when a bad detachment occurs, they can deviate out of contact with the fusing roll and partially rotate in that manner. The fingers are mounted for 360 degree rotation partly by the heated and partly manually heated fuser roller.

The patent of the U.S.A. No. 4,771,310 discloses a releasing fingers mechanism with flexible release fingers arranged in such a way that the ends of fingers are angled against a merging roller surface to check initial separation of a merged copy sheet. The fingers have centrally located raised edges to provide a rigid, inclined support that gradually lifts the fused copy sheet following initial separation. The above references are incorporated herein by reference. COMPENDIUM OF THE INVENTION One aspect of the invention is directed to an apparatus for moving a stripping bar assembly near a paper path that includes a housing; a release bar having a first end and a second end, with at least one stopper finger conested, the release bar is rotatably mounted in the housing and close to the paper path; a cam member located at the first end of the release bar; a cable having a first end and a second end, the first end of the cable is connected to the cam member; and a movable member, which moves from a first site to a second site, the second end of the cable is connected to the movement member, such that when the movement member moves from the first location to the second location, the The release bar rotates in a first direction and moves the detaching finger at least away from the paper path. Another aspect of the invention is directed to a method for moving a detachable bar of a paper tray which involves rotating the release bar in a housing, the release bar has at least one finger detached and a cam attached in a first extreme; connecting a cable with a first end and a second end, the first end of the cable is con - tained to the cam end of the release bar and the second end of the cable is con - sisted to a movable member; and moving the movable member from a first site to a second site, which provides for the release bar to rotate in a first direction from a first position to a second position, causing the release finger at least to move away from the paper path. In an existing fuser assembly, a rigid articulation with the stripping wall to the upper sub-assembly of the merger assembly, such that when the upper sub-open is opened, the drag bar rotates and moves the detaching fingers away from the merger roller and away from the set-up potential of a piece jammed with paper. However, in the rigid articulation configuration, the rotation of the detaching bar is limited and does not sufficiently move the detaching fingers out of the path of passage of an operator attempting to release the paper path. The present invention solves the problem of limited breaker bar rotation by replacing the rigid articulation connection with a cam-cable connection. The cam and cable connection results in a higher degree of rotation of the release bar with the same degree of rotation of the upper cover, which allows the detaching fingers to move completely out of the samino of an operator that releases a paper jam in the fusion assembly. Additional developments resulting from the extended breakdown of the breaker bar include a key position assembly that is used to properly position the mounting bar during service operations and an expensive side to avoid over-rotation. BRIEF DBSCRIPCIOH DB THE PIBWPS Other characteristics of the present invention will be apparent as it proceeds in the following description and with reference to the drawings wherein: Figure 1 is a schematic view of an electrophotographic copying machine; Figure 2 is a side view of a rigid articulation connection of the prior art with the closed top cover; Figure 3 is a side view of the rigid hinge connection of the prior art with the top cover open; Figure 4 is a side view of the cam and cable connection with the top cover closed; Figure 5 is a side view of the cam and cable connection with the top cover open; Figure 6 is a side view of the key position mechanism for cable connection / disconnection; Figure 7 is a side view of a key position mechanism for front access bar breaker; and Figure 8 is a side view of the feature to avoid over rotation. While the present invention will be described in connection with a preferred embodiment thereof, it will be understood that it is not intended to limit the invention to that embodiment. On the contrary, it is intended to cover all alternatives, modifications and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims. DETAILED DESCRIPTION OF THE INVENTION Now with reference to the drawings, wherein the illustrations are for the purpose of describing a preferred embodiment of the invention and not to limit it, the various processing stations employed in the reproduction machine illustrated in the Figure 1, they will be displayed only briefly. It will undoubtedly be appreciated that various elements of prosecution also have an advantageous use in ergonomic printing aplombs from an original souled alloy. A reproducing machine wherein the basic principles of the present invention find advantageous use employs a photoreceptor band 10, the band 10 moves in the direction of the flesha 12 to advance sussential passages of the band sessually through the various processing stations. arranged with respect to the trajectory of their movement. The band 10 is trapped with respect to the release roller 14, tension roller 16, secondary rollers 18 and impulse roller 20. The drive roller 20 is coupled to a motor (not shown) by convenient moving means such as a band. The band 10 is held in tension by a pair of springs (not shown) that resiliently moves the tension roller 16 against the band 10, with the desired spring force. Both the stripping roller 14 and the tension roller 16 are rotatably mounted. These rollers are secondary, which rotate freely as the band 10 moves in the direction of the arrow 12.

With referensia sontinua to Figure 1, inisially a porsión of the band 10 passes through the sergesion of serge A. In the sergesion of serge A, a pair of devices sorona 22 and 24 serge the photoresistor band 10 to a relatively negative potential high, substantially uniform. In exposure slot B, an original document with the sara down is placed on a transparent stage 30 for illumination with flash lamps 32. Light rays, reflected from the original document are reflected through a lens 34 and project onto a charged portion of a photoreceptor band 10 to seletively dissipate the twill. This records a latent elestrostátisa image in the band that corresponds to the information area contained within the original document. Subsequently, the web 10 advances the latent elestrostátisa image to the developing station C. In the developing station C, a developing unit 38 advances one or more colors or types of developer mixture (ie, carrier and organic pigment granules) in contact with the latent electrostatic image. The latent image attracts the organic pigment particles of the carrier granules thus forming organic pigment images in the photoreceptor band 10. As used herein, organic pigment refers to finely divided dry ink, and suspensions of organic pigment in liquid.

The band 10 then advances the revealed latent image to the transferensia stasis D. In the transferensia stasis D, a sheet of support material such as a paper sheet moving in contact with the latent image developed in the band 10. First, the latent image in the band 10 is exposed to a pre-transfer light from a lamp (not shown) to reduce the attraction between the photoreceptor band 10 and the organic pigment image. Next, the corona generating device charges the copy sheet to the appropriate potential such that it adheres to the photoreceptor band 10 and the organic pigment image is attracted from the photoreceptor band 10 to the sheet. After transferensia, a sorona generator 42 loads the copy sheet with an opposite polarity to detach the copy sheet from the web 10, whereby the sheet is detached from the web 10 in the stripper roller 14. The support material can also be to be a surface or intermediate member, which transports the organic pigment image to a subsequent transfer station to transfer to a final substrate. These types of surfaces are also retentive of charge in nature. In addition, while the band-like members are described herein, it will be recognized that other adaptable or substantially non-rigid members may also be employed with the invention.

Sheets of support material are advanced to the transfer station D from the supply trays 70, 72 and 74, which can hold different amounts, sizes and types of support material. The sheets are advanced to the transfer station D on the conveyor 76 and rollers 78. After transfer, the sheet continues to move in the direction of the arrow 51 towards the conveyor 50 advancing the sheet to the merger station E. The station The merger E includes a merger assembly, indicated generally by reference number 52, which permanently fixes the organic pigment images transferred to the sheets. Preferably, the fuser assembly 52 includes a heated fusing roll 54 and a pressure roller 56 with the image of organic pigment in the copy sheet contacting the fusing roll 54. The pressure roller 56 buttresses the fusing roll 54, to provide the necessary pressure to fix the organic pigment image to the copy sheet. The channel 60 guides the advancing sheet to the trapping tray 80 or a finishing station for binding, stapling, collating, and separating from the machine by the operator. Alternatively, the sheet can be advanced to a duplex tray 90 via the duplex gate 92 from which it will be returned to the processor and conveyor 76 to receive second-side images.

A previously cleaned sorona generating device 94 is provided to expose the residual organo pigment and polyacrylates to solon (hereinafter referred to as an organo pigment) to thereby stress the distribution of twill for more effective separation and a cleaning stain of 50%. It is contemplated that the residual organic pigment remaining in the photoreceptor band 10 after transfer will be recovered and returned to the developing station C by any of various well known recovery assemblies. As has been described up to this point, an agreement reproducer machine is the present invention can be any of several well-known devices. Variations can be expected in specific prosecution features, handling assemblies and paper sonols without affecting the present invention. Figure 2 shows the rigid articulation support mechanism and release rod of the prior art. The fusing roll 54 is supported in the fusing assembly 52 at both ends by grease bearings 55, supported by holes in lateral fusing roller supports 53. The release rod 100 is an elongate member that extends over the length of the roller merger 54. Stripping rod 100 is pivotally supported by lateral merging roller supports 54 on stripping rod pivot 102. One or a plurality of stripping fingers 104 are mounted on stripping bar front 106 with detachable finger connecting elements. 105. The connecting elements 105 can be in the form of any fastener that allows easy replacement of the detaching fingers and in the illustrated embodiment are screws. The base of the release bar 108 is configured such that when the release fingers are in their annealed operating position, the release bar base 108 rests on the stop pin 110. The stop pin 110 is also mounted on the supports 50. The springs 113 at both ends of the fusing roll have one end connected to the stripping bar 100 and the other end conested to the lateral supports of the fusing roller 53 and derive the stripping bar to the stop pin 110, so such that the breaker bar base 108 comes into contact with the stop pin 110. The stop pin stops the clockwise rotation of the breaker bar and locates the breaker bar, and thus the detaching fingers, in the correct operating position. The detaching bar is connected to the upper cover 130 by a rigid articulation mechanism, such that when the upper cover is opened, the release bar rotates, moving the detaching fingers in a direction that is analogous to the direction of the clock hands, far of the fuser roller 54. The upper part of the stripping bar 112 has a stripping bar artisulasion 114 are one end rigidly to the stripping bar, and the other end to an articulating lever 116 in the stripping rod artislation pin 118. The other end of the articulation palata 116 is connected to the upper subclamp articulation 120 in the upper sub-clamping artisulary pin 122. The end of the upper cover joint 120 opposite the upper sub-clamping articulation pin 122 is rigidly cast to the upper sub-piece 130. The upper cover 130 is pivotally mounted to the mounting frame fus Ionator 132 in upper sub-kingpin 134. Upper cover 130 has an upper sub-side 136 associated with the end to the upper deck. In the closed upper deck position, an angle, is formed between the upper cover and a horizontal line such as one through the upper cover pivot 134 and an angle, is formed between the release finger 104 and a vertical line such as that through the finger peel 102. In the illustrated embodiment, ßl is approximately 23 degrees and fl is approximately -150 degrees.

Figure 3 shows the same rigid articulation configuration as Figure 2, however with the upper cover 130 of the fusion assembly 52 in the open position. The upper cover side 136 rests against a rail (not shown) which is mounted on the side of the fusion frame 132, stopping the rotation of the top cover and thus that of the gripper bar. The weight of the upper cover 130 is sufficient to overcome the force of the springs deriving the detaching fingers towards the fusing roll, such that the upper cover remains in the open position. In the fully open position, a new angle?, T2, is approximately 169 degrees, and a new angle f, f2 is approximately 72 degrees. In this way the difference between? L and? 2, the upper cover rotation is 146 degrees and the difference between fl and 02, the release bar rotation is 78 degrees. As can be seen, the 78 degrees of rotation of the stripping bar 100 results in the detaching fingers 104 limiting the acse to the jammed paper area J. As explained above, the stripping fingers 104 are made of flexible material and their shape and orientation It is critical for proper detachment of the paper from the fusing roll. It is expedient to move the detaching fingers 104 completely out of the paper jam path so that an operator releasing the jam does not come into contact with the detaching fingers, nor does the release paper contact the release fingers. The cable and cam mechanism of the present invention is illustrated in Figure 4. The rigid articulation mechanism has been replaced with a cam 200 at one end of the release rod 100 and a cable 210 connecting the cam to the top cover link 120. The cable 210 is releasably connected to the upper cover joint 120 in the opening 124 by a pin 212 at one end, the other end is connected to the cam at 214. The cable is wrapped around the cam as illustrated. A torsion spring 216 is connected to the end of the release rod opposite the cam end and is used to derive release fingers 104 towards the fusion roller by turning the release bar to its operative position when the top cover 130 is in the closed position. . Again, the stop pin 110 stops rotation of the release bar 100 when the release bar base 108 abuts the stop so that release fingers 104 are properly positioned with respect to the fusion roller. The angles? L and fl are the same as in Figure 2; It is approximately 23 degrees and fl is approximately -150 degrees. Figure 5 shows the upper cover 130 in the open position. As the upper cover 130 opens, the cable 210 unwinds from the cam 200 and rotates the release bar 100 as well as causing the torsion spring 216 to tighten. In the fully open position, the new angle?, T2, is again approximately 169 degrees. However, the new angle f, f2 is approximately 32 degrees. The difference between? L and? 2, the top deck rotation, is 146 degrees and the difference between fl and f2, the breaker bar rotation is 182 degrees. The increased angle of rotation of the detaching bar moves the detaching fingers 104 far from the path of the access space to the paper jamming area J. When implementing the cam and cable mechanism of the present invention, sacsterlstisas adisionaleß were developed to assist in give servisio to the fusion assembly. The first of these refers to giving ßervisio to the detaching fingers. When the detaching fingers are replaced, which is a frequent operation, it is necessary to rotate the detaching bar in such a way that the elements that connect the detaching finger 105 that keep the detaching fingers in the detaching bar are accessible to the person providing the service. This requires that the tops of the connecting elements 105 point more or less vertically up when the upper merge cover is open. Nevertheless, with the cable connected and the top cover open, the screws point below horizontal and to the left and are inaccessible to the service person. In this way it is necessary to de-scale the saber, allowing the detaching shell to rotate back to the point where the upper parts of the elements 105 are accessible. The procedure for doing this is as follows and involves the key 250 (illustrated in Figure 6), in a preferred embodiment a 5 mm Allen key, having a long session 252 and a sorta session 254, at resilient angles to each other. With the saber saber and the open fuser cover open, the release bar is manually rotated counterclockwise until the end of the long section 252 of the key can be inserted into the opening 101 provided in the opening. breakout bar. The release bar and the key are then allowed to turn clockwise until the key rests on a cover 138, which is on a cross bar 111 that is fixed to the fusion assembly. The angle of rotation of the release bar, the positioning and profile of the opening in the release bar, the length and size of the key and the position of the crossbar and cover are designed in such a way that the cable 210 has clearance when the The key is in the position illustrated in Figure 6, allowing the service person to have both hands free to remove the pin 212 that holds the cable to the upper cover joint 120, thereby disconnecting the cable. This configuration also allows the saber to be easily reconnected from the key assembly by suitably positioning the release bar for easy insertion of pin 212, into opening 124. A special interest in this operation are paper guides 260, which will be discussed further with respect to Figure 8. With the pin removed and the cable disconnected, the next step in servicing the fingers of the pickers is to remove the key 250 and manually turn the release bar clockwise until the opening in the bar detaching is more or less vertical, as illustrated in Figure 7. The end of the short section 254 of the key is then inserted into the opening 101 and the long end 252 of the key is allowed to rest on the cover 138. With the driver bar and the key in this configuration, the upper covers of the connecting elements 105 are now accessible, allowing them to be removed for replacement of the fingers of clients. This entire procedure is then reversed when the service is completed, bringing back to the condition when the cable is connected to the top cover. Another additional feature incorporated in the design refers to the over-rotation of the release bar. As explained with reference to Figure 6, when performing service operations, the release bar is manually rotated beyond the open cover orientation in order to loosen and remove the cable. During this operation, the release bar may be over-rotated in the counterclockwise direction, causing the tips of the paper guides 260 to enter in contrast with the merger roller 54. The contact of the paper guide with the fuser roller it is highly undesirable because the paper guides can be grooved and deface the surface of the fuser roller. In order to avoid over-rotation of the release bar, and as illustrated in FIG. 8, the upper part of the release bar 112 is configured in such a way that you counted the fusion roller bearing 55 and stops rotation in the opposite direction clockwise of the release bar before the paper guides contact the fuser roll surface. Therefore it is apparent that it has been provided in accordance with the present invention, a relatively simple cable and cam mechanism used to rotate a release bar assembly that fully satisfies the previously established objectives and advantages. While this invention has been described in conjunction with a specific embodiment thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, it is intended to cover all these alternatives, modifications and variations that fall within the spirit and broad scope of the appended claims. It is noted that in relation to this date, the best method conosido by the solisitante to bring to the prástisa the invention, is the convensional for the manufacture of the objects to which it refers.
