Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea is based on image forming equipment such as copying machines, printing machines, and laser beam printers. A sorter attached to the machine that sorts and stores sheets output from the image forming apparatus. Specifically, it has a large number of bins, and aligns and binds the sheets stored on the bins. The present invention relates to a sorter equipped with a stapler device.

0002

[Conventional technology]

Conventionally, machines equipped with a stapler device that staples sheets ejected from copying machines, etc. As a sheet post-processing device, it is used in conjunction with machines such as a circulating automatic document feeder (RDH). , there is a sheet post-processing device (finisher) that staples each sheet. However, it has the disadvantage that the mechanism is complicated and expensive.

0003 (1) A relatively simple bin-moving type sorter with a stapler attached (unexamined patent application) Publication No. 64-43457) has been disclosed. This device binds sheets stored in a bin. This is a sorter in which a stapler device is arranged so that it can move forward and backward relative to the bins.

0004 (2) With other sorters, when stapling each stack of paper, the A stapler device is provided for each bin, and each bin is moved to the stapling position. There is a format in which the staples are driven into the stack of paper.

[0005] (3) The sorter disclosed in Japanese Patent Application Laid-Open No. 62-244869 is capable of stapling. Move the bin loaded with paper to a suitable position, then staple the paper, and then Stapling is performed by moving the stapler device vertically.

[0006]

[Problem that the idea aims to solve]

Of the above-mentioned sorter with a stapler device, move the first stapler device forward and backward. For the format, the approach process differs depending on the sheet size, and the vertical spacing of each bin is If it is wide, the sorter will become large, and the distance between the bins that the stapler device enters will be limited. There was a problem in that the mechanism became complicated when the expanding operation was performed. Also, this saw A large closed-loop long hole is drilled in the bottle, and a common alignment for all bottles is placed inside the long hole. The alignment member is made swingable by inserting a member therethrough. But something like this For the bin shape, after assembling all the bins into the sorter body, insert the matching member into the long hole. The alignment member must be inserted into the , disassembly, adjustment, etc. require a large amount of work time. Also, sheets with different sheet sizes is stored in the bin based on the center, and the bin is moved to the stapling position. In the type sorter, the long holes have to be made larger, so the bins become larger. There are drawbacks.

[0007] In the second sorter, the overall configuration of the sorter becomes complicated and the bin spacing is narrow. However, there was a problem in that a special stapler device was required.

[0008] In the third sorter, each bin loaded with paper is moved straight along the bin guide at the appropriate time. The device is moved horizontally to the stapling position, making the structure of the device complicated. There is a point.

[0009] On the other hand, in a sorter equipped with a stapler device that moves the bins, when the bins are returned If the bin does not accurately return to the initial stop position and stop, the next sheet stack will fail. , the rear end of the sheet stored in the bin rides on the top of the rear end stopper of the bin, Problems such as poor sheet ejection, paper jams, and poor sheet alignment occur.

0010

[Means to solve the problem]

This invention solves the above problems and returns the bottle to its initial predetermined position when the bottle swings back. It stops the sheets reliably and stably at the same position, ensuring that the sheets are aligned in the bin (paper alignment) and stabilized. The purpose of the present invention is to provide a sorter equipped with a stapler device that realizes stapling with That is.

[0011] A sorter equipped with the stapler device of the present invention that achieves this purpose is an image forming device. A plurality of bins for sorting and storing sheets carried out from the main body, and a structure in which the bins are oscillated. a bin swinging device that moves the sheets stored in the bin to a binding position; and a stapler device for stapling sheets, the sorter comprising: a stapler device for stapling sheets; A spring member is stretched between one end of each bin and the fixed part of the sorter body, and the front When the bottle swinging device moves back, the bottle is initially moved by the biasing force of the spring member. Return to the initial position, press the reference wall surface of the bin against the reference fixed surface of the sorter body, and stop. The feature is that it stops.

【Example】

Embodiments of the present invention will be described below with reference to the drawings.

[0013] FIG. 1 is a configuration diagram of a sorter connected to the main body 1 of an image forming apparatus (for example, a copying machine). Ru. The sorter of the present invention includes a base section 10, a downward conveyance section 20, an upward conveyance section 30, and a bin transfer section. It is composed of a moving part 40.

The base section 10 includes casters 11, a connection means 12 to the main body of the image forming apparatus 1, and a conveyor belt 1.
3. It consists of a driven roller 14, a guide plate 15, a driving means (not shown), etc., and is fixed on the floor.

[0015] In addition, a stay member 16 is fixed to the base portion (horizontal conveyance portion) 10 in a direction perpendicular to the plane of the paper in FIG. It is set up. A rack gear RG is fixed to the upper surface side of the stay member 16. On the other hand, rollers 17A and 17B for moving the casing are rotatably supported inside the casing of the bin moving unit 40, which will be described later. The rollers 17A and 17B slide on rails (not shown) of the base section 10. , the casing of the bin moving unit 40 is movable in a direction perpendicular to the plane of the paper. In other words, the above bit A drive motor M1 is installed inside the housing of the main moving unit 40, and drives gears G1 and G2. The pinion gear PG is driven and rotated through the pinion gear PG. The pinion gear PG is connected to the stay member. Since it meshes with the rack gear RG fixed to the The casing of the bin moving unit 40 moves in a direction perpendicular to the plane of the paper. In addition, 18 is the pinion gear PG 18 is a rotatable roller provided coaxially with the stay member 16 and serves as a guide. do.

[0016] The downward conveyance section 20 is connected to the paper ejection roller 2 and paper ejection port 3 of the image forming apparatus main body 1, and is The paper sheet P is received by the guide plate 21 and conveyed downward, and is conveyed within the base section 10. It consists of a conveyor belt 22 for feeding onto the belt 13, a driven roller 23, and the like. Also, this When a jam occurs in the ADF or sorter after branching from the conveyance path, the image forming device main A conveying means 24 and a tray 25 are provided for discharging the preceding sheets in the body 1. In addition, the above The upper part of the housing of the downward conveyance section 20 swings freely to open and close, and the jammed paper in the downward conveyance section 20 is removed. It makes it possible to take out the

[0017] The upward conveyance unit 30 includes pulleys rotatably fixed to the upper and lower parts of the support frame. A plurality of endless transfer belts 31 are stretched between the belts 32 and 33. The conveyor belt 31 On the inside, a plurality of rollers 34 are rotatably connected to each other, corresponding to the bottle insertion slot described later. are doing. A plurality of conveyor rollers are disposed on the outside of the conveyor belt 31 facing the roller 34. 35 is in contact and driven to rotate.

[0018] In addition, branch guides 36 are located at the entrances of the bins in the middle of the conveyance rollers 35. Place and rock. These branch guides 36 are connected to a shaft 37 installed on the support frame. The shaft 37 is rotatably supported by a lever and a solenoid (not shown) provided at the shaft end of the shaft 37. It is rocked by the noid. Therefore, the branch guide 36 must be rotated clockwise. , the lower end claw of the branch guide 36 is made up of the conveyor belt 31 and the conveyor roller 35. The branch guide 36 adjust the posture to accept the paper. When the paper P is conveyed there, the paper P It is deflected in a substantially right angle direction along the inner curved surface of the branch guide 36 and received in the bin 41. It will be done.

[0019] 2 and 3 are partial cross-sectional views of the constituent members and bins of the paper branch conveyance path, FIG. 2 shows the vicinity of the upper part of the sorter, and FIG. 3 shows the vicinity of the lower part of the sorter. Also, Figure 4 A top perspective view of the bottle, FIG. 5 is a plan view of the bottle and related components.

[0020] In the bin moving unit 40, a plurality of bins (for example, 20 bins) 41 arranged at equal intervals are oscillated. freely supported. In other words, the bottom of bottle 41 (left side in Figures 2 and 3) It is slidably supported on a guide plate 48 fixed to the moving part 40.

[0021] Note that 41A indicates three locking points provided on the bottom side that engage with the notches of the guide plate 48. This is the claw part. 41S has five stopper walls ( The upper end of the upright surface has a curved claw portion 41B in the shape of an eave. It protrudes inside the bin 41 and prevents the paper P from coming out of the bin due to the rear edge of the paper rising up. To prevent.

[0022] It is directly supported by support members 42A and 42B fixedly installed above and below the frame of the bottle moving unit 40. A slide piece 44 is fitted onto the fixed support shaft 43 that stands upright, and is secured by a pin 45 and an E-ring 43E. Positioned. One of the bins 41 is attached to the inclined neck portion of the slide piece 44. The U-shaped groove 41G at the end (Figs. 4 and 5) is fitted to allow the bin 41 to freely rotate in an inclined manner. . In addition, pins 45 and E-rings 43E driven into the fixed support shaft 43 at equal intervals are The dowel pieces 44 are supported at equal intervals, and the ends of the bins 41 are held in parallel alignment at equal intervals.

[0023] Thus, each bin 41 is equally spaced with the fixed support shaft 43 at a horizontal inclination angle α (for example, 30°). They are arranged parallel to each other and can be tilted and swung at the above-mentioned inclination angle α.

[0024] The other end of the bottle 41 is installed in a part of the frame of the bottle moving unit 40 and rotates. Supported by the flexible Koro 39. In this way, the bin 41 is connected to the guide plate 48, the slide It is supported by a dome 44 and a roller 39, and is able to swing freely around a fixed support shaft 43. Ru.

[0025] Further above the plurality of bins (20 stages of sorting bins in FIG. 1) 41, there is a deep-bottom type nozzle. A sorting bin 49 is fixedly installed. The non-sort bin 49 contains images that do not require sorting. This is a bin that stores formed paper P, and a large amount of 100 to 300 sheets of paper can be stacked. be.

[0026] The sheet loading surface of the bin 41 is a stopper wall that aligns the sheets by abutting the rear end of the sheet. 41S and a lower mounting surface 411 that is perpendicular to the horizontal plane and forms a gentle inclination angle (for example, about 10°); It is connected to the component mounting surface 411 via a curved surface 414 and forms a steep angle of inclination (for example, about 40°) with the horizontal surface. An intermediate placement surface 412 connected to the intermediate placement surface 412 and at an angle of α (for example, approximately 30°) with a horizontal surface. ) and an upper mounting surface 413.

[0027] The stopper surface 41S near the base of the bottle 41 and the lower mounting surface 411 form an angle of 90°. This ensures that the stack of paper is aligned when stapling. In addition, the stopper surface 41S is close to vertical, and by making the lower loading surface 411 at a gentle angle, buckling of the leading edge of the paper is prevented. This prevents the paper P from sliding down the slope and ensures that the paper is aligned.

[0028] Since the intermediate placement surface 412 is formed at a steep angle, the material is not discharged onto the bin 41. The paper P that has been loaded will surely slide down due to its own weight, and the paper alignment will be performed reliably. this This ensures that paper that is charged with static electricity and tends to stick to the surface, or paper that is curled, can be reliably removed. The paper slides down and the trailing edge of the paper hits the stopper surface 41S.

[0029] The inclination angle α of the upper mounting surface 413 is slightly smaller than the inclination angle of the intermediate mounting surface 412. Since the angle is set at a wide angle (approximately 30°), the distance between multiple bins 41 can be kept to a minimum, Moreover, it is possible to reduce the height of the entire sorter. Also, this upper mounting surface 413 Large sheets of paper (for example, B4 size, A3 size) are ejected and flown onto the bin 41 and are placed there. Since these large sheets of paper have a large weight, the slope angle α and the steep slope angle of 412 (approximately 40 degrees) so that it slides down enough to align the paper. Sow at the top of bin 41 A non-sorting bin 49 fixed to the main body of the machine also has almost the same shape as the bin 41.

[0030] The plurality of stopper walls 41S for aligning the rear ends of the sheets P are located at the left end of the bin 41 in the illustration. It is desirable that the paper sheets of all sizes are provided so that they come into contact with each other. However, each bit A software that minimizes the distance between the bins 41 and swings the bins 41 for stapling. In this case, the upper end of the stopper wall 41S touches the bottom of the upper bin 41 when the bin swings. There may be contact or collision.

[0031] In order to prevent interference and collision between the upper and lower bins, there are five stopper walls 41 on the bin 41. Of the upright wall surface with S, the part that interferes with the lower bin 41 is cut out. (Part A in Figures 4 and 5).

[0032] On the other hand, the bottle 41 is placed on the upright surface 48A of the guide plate 48 on which the rear end bottom surface of the bottle 41 is placed. An auxiliary reference plate 47 was integrally fixed at a position corresponding to the notch A of the ring 41. The auxiliary reference plate 47 has the same shape to compensate for the stopper wall 41S that is missing due to the notch of the bottle 41. It has three stopper walls 47S. The upper end of the upright surface of the stopper wall 47S is curved. A claw portion 47B protrudes like an eave and has the same shape as the claw portion 41B.

[0033] The spring 59 is attached to the upright surface 48A of the guide plate 48 fixed to the bin moving section 40 of the sorter body. It is a tension coil spring stretched between one end 48B and one end 41E of the bottle 41. . The spring 59 biases the bottle 41 during the return process of swinging the bottle by the bottle swinging device 70, which will be described later. to return to the initial position, press the bottle 41 against the upright surface 48A of the guide plate 48, and stop it. Ru. Then, the bottle 41 is urged by the spring 59 and is brought into close contact with the upright surface 48A of the guide plate 48. In this case, the stopper walls 41S and 47S are on the same surface, forming a reference surface for abutting the trailing edge of the paper. to be accomplished.

[0034] Further, the claw portions 41B and 47B have the same shape and the same height. Bin 41 is rocking as described below. When swung by the means 70, the trailing end of the stack of sheets placed on the bin 41 It is swung to the stapling position while in contact with the upper wall 41S, but it is fixed to the guide plate 48. The stopper wall 47S provided on the auxiliary reference plate 47 is left at a fixed position. follow When the upper bin 41 is swung, the lower stopper wall 47S touches the bottom of the upper bin 41. There will be no interference with the department.

[0035] The paper P (dotted chain line shown in FIG. 3) carried into the upward conveyance section 30 of the sorter at high speed is It rises while being held between the belt 31 and the conveyor roller 35, and is operated by a solenoid (not shown). to the right by the branch claw 36 (shown, the second row from the bottom) that is swung clockwise. The claw portion 41B of the bottle 41 and the claw portion of the auxiliary reference plate 47 are deflected (dotted chain line in FIG. 3). Passing through the upper opening of 47B, the curved surface 414 and inclined surface 412 of the bottle 41 and the rib at the bottom of the upper tier It passes between 41R and rises to the right, and the trailing edge of paper P passes the pressure contact position between belt 31 and roller 35. After that, the paper P is ejected according to the ejection speed, and further, the trailing edge of the paper hits the stopper wall 41S. , 47 After passing above S, the paper P changes from rising to descending, and the weight of the paper P The paper P slides down on the inclined surfaces 413, 412, 411 of the bin 41, and the rear end of the paper P slides down on the stopper walls 41S, 4 It hits 7S and stops. The subsequent paper P is also carried into the bin 41 in the same way, The preceding sheets P on the bin 41 are switched back and the sheets are aligned.

[0036] On the other hand, a part of the fixed frame of the upstream transport section 30 has a An alignment device 50 is provided to align the side edges of the sheets P to be discharged. (Figures 2, 3, 5 , 6). The alignment device 50 fits into the upper support shaft attached to the upper part of the frame. The upper arm 55, which can swing freely, is swung by the driving force of a pulse motor (not shown). It will be done. At the tip of the upper arm 55, the upper shaft end of the mandrel of the alignment rod 54 is held by an alignment bearing. held. The lower shaft end of the mandrel of the alignment rod 54 is aligned with the shaft end of the lower arm 52. It is fitted and held in a bearing.

[0037] The outer periphery of the mandrel of the alignment rod 54 is covered with an elastic material made of foam material such as sponge. The width of the paper P is adjusted by pressing against the side edge of the paper P to be discharged. matching The rod 54 draws a swing locus (dotted chain line) as shown in FIG. Meanwhile, bin 41 is loaded In order to insert the paper P into the stapler device 80, the paper P is oscillated as shown by the dashed line in FIG. do.

[0038] A stopper wall 41D stands upright and is integral with one side of the bottle 41. A paper pressing device 60 is attached to the outer surface of the stopper wall 41D. The stopper A lever 61 is swingably supported on a shaft 62 installed in the wall 41D. The lever 61 A paper pressing member 63 is attached to one end.

[0039] The other end of the lever 61 is connected to a lever attached to the tip of the arm 71 of the bin swinging device 70. 72. This pressure causes the lever 61 to swing and press the paper presser member. 63 presses the top surface of the paper P on the bin 41 to press the paper.

[0040] Further, the board of the bin swinging device 70 is common to the board of the stapler device. It is attached to a frame body and is lifted up and down by a lifting device on the frame of the bin moving unit 40. It is driven downward, stops at each bin 41, and moves forward while being pressed by the paper pressing member 63. The stack of sheets accumulated on the oscillated bin 41 advances to the gap between the binding parts of the stapler device. The staples are driven in.

[0041] After driving the staple, the arm 71 swings back and the bin 41 is biased by the spring 59. Then, it swings back and returns to the initial paper ejection position.

[0042] Next, the stapling operation of the bundle of sheets discharged into the bin 41 will be described below.

[0043] Used as a reference for placing the document on the platen glass of the image forming apparatus main body 1. There are a center line standard and a one side alignment standard. Below, the center line The stapling operation of the paper bundle P will be described with reference to FIGS. 6 and 7. Figure 6 is FIG. 7 is a plan view showing the accommodation and alignment of sheets on the bin 41. FIG. FIG. 3 is a plan view of the stapled state.

[0044] (1) The size of the paper (copy paper) P ejected from the image forming apparatus main body 1 is manual. When set or automatically determined, the bin moving unit 40 of the sorter is electrically driven to move the paper When it reaches a predetermined position corresponding to the size, it is stopped by a signal from the position detection sensor and waits. It becomes machine state. The maximum movement amount of the bin moving unit 40 is the maximum paper size width (for example, 17 inches). half of the minimum size width (e.g. B5 size, 257 mm) (e.g. 87.4 mm) ) is set. Also, in this standby position, the stopper wall 41D of the bottle 41 is It is located at a position spaced apart by δ (for example, approximately 10 mm) from the widthwise side edge of the sheet P to be inserted. (2) In this state, the paper P enters from the left side in the figure and rises along the slope of the topmost bin 41. It then slides down due to its own weight and hits the stopper wall 41S of the bottle 41 and the auxiliary reference plate 47. It comes into contact with the topper wall 47S and stops.

[0045] (3) After the paper P has stopped, the alignment rod 54 swings and presses one side edge of the paper P. Then, shift the paper P to the front side by the shift amount δ, and place the other side edge of the paper P against the stopper wall 41D. bring it into contact. This offset amount δ is different from that of paper of different sizes (for example, A4 size, B4 size). , A3 size, etc.) are set almost equally.

[0046] (4) Subsequent paper P is placed in the lower second bin 41 by switching the branch guide 36. After being ejected, the alignment rod 54 similarly swings and presses the side edge of the paper P, thereby aligning the paper P. P is brought into contact with the stopper wall 41D to align the paper.

[0047] (5) In the same manner, the documents are distributed and stored one after another in the number of bins 41 corresponding to the number of originals. Ru.

[0048] (6) A CPU-controlled counting device indicates that the set number of sheets P has been stored in the topmost bin 41. The tray detects that the rear end of the final paper P stored in the bin 41 passes through the bin moving unit. Light detection that connects the light emitting element LED installed at the top of the 40 and the light receiving element PTr installed at the bottom of the same When it is detected that the optical path of the means is open, the discharge into the first stage bin 41 is completed. (See Figure 1).

[0049] (7) Similarly, as soon as the completion of paper ejection into bin 41 of the second stage is detected, or After a predetermined period of time has elapsed, the topmost bin 41 is swung by the bin oscillating device 70. . That is, when a stapling signal is input to the stopped bin moving unit 40, first the previous bin moving unit 40 is The recording bottle swinging device 70 is driven, the arm 71 swings, and the roller 72 at the tip moves against the paper presser. Press the leaf spring 66 at the lower end of the device 60, and then resist the spring biasing force of the leaf spring 65 at the upper end. , by swinging the lever 61 counterclockwise around the shaft 62, the paper pressing member 63 presses the top surface of the sheet on the bin 41.

[0050] (8) Continuing, the roller 72 at the tip of the arm 71 further moves the bin 41 around the slide piece 44. While pressing the sheet, the bin 41 is swung (for example, θ=12°).

[0051] (9) The sensor of the bottle swing device 70 detects the swing position and the swing of the bottle 41 is stopped. (10) At this stop position, the rear end corner of the paper bundle is placed in the gap between the binding parts of the stapler device 80. The stapler 83 is driven by the stapler device 80 and stapled. Ru.

[0052] (11) After stapling is completed, the arm 71 is driven and returns to its original position, causing the bin 41 to is biased by the spring 59 and returns to its original position, and the paper presser member 63 is removed from the paper stack surface. The stack of sheets can be taken out from above the bin 41 by being separated upwardly.

[0053] (12) Stapling of the paper bundle stored in the topmost bin 41 of the bins 41 is completed. Then, the unit formed integrally with the stapler device 80 and the bottle swinging device 70 moves up and down. It is lowered by the device, and almost at the same time, the bin 41 one level below is swung, and the bin 41 is moved down in the same way as before. A staple motion is performed. During this time, paper is ejected to bin 41, which is one or two steps lower. is being carried out.

[0054] (13) Once all the paper stacks have been stapled, connect the bin swinging device to the The unit integrated with the taper device returns to the top bin position.

[0055] Note that the stapling operation described above is performed from the image forming apparatus main body 1 based on the center line. This is a sorter that stores, aligns, and staples discharged paper, but the present invention This is not limited to this, and the paper is ejected from the device main body 1 on a one-sided basis and stored. It can also be applied to a sorter that aligns and staples paper.

[0056]
