[0035]
FIG. 2 shows details of the peeling claw 13, the upper paper discharge guide 14 and the peeling claw support frame 15.
A plurality of the peeling claws 13 are provided at predetermined intervals, and each of the peeling claws 13 is formed in a substantially square shape in a side view. One end portion thereof is a claw portion 13a formed in a sharp shape, the other end portion thereof is provided with a recessed portion 13b, and the upper end surface thereof is a so-called upward inclined surface 13c.
[0036]
A through hole 13d is provided in a substantially central portion of the peeling claw 13, and the shaft 22 is loosely inserted therein. That is, the peeling claw 13 is pivotally supported with respect to the shaft 22. Only both end portions 22a of the shaft 22 are formed to have a diameter smaller than that of the peeling claw loose insertion portion.
[0037]
The upper paper discharge guide 14 is made of a plate having a plate surface with a predetermined width along the copy paper conveyance direction. A reinforcing plate 23 that reinforces the plate surface is integrally provided on the upper surface portion, and a fixed frame 24 as a rising tongue piece is provided on the left and right sides of the reinforcing plate 23 in the short direction of the upper paper discharge guide 14 ( It is erected along the same direction as the copy paper conveyance direction. The fixed frame 24 is provided with a pivot hole 25 and a screw hole 26 in parallel with each other at a predetermined interval.
[0038]
Furthermore, a receiving portion 27 is provided in the vicinity of the fixed frame 24 along the short direction of the upper paper discharge guide 14. The receiving portion 27 is a substantially U-shaped concave portion, and the curvature radius of the curved surface portion is formed to be the same as the radius of the shaft end portion 22a.
[0039]
A positioning recess 28 is provided between the receiving portions 27 on both the left and right sides with a predetermined interval. These positioning recesses 28 are provided corresponding to the attachment positions of the peeling claws 13 and are set to a width dimension such that the peeling claws 13 can be inserted.
[0040]
The peeling claw support frame 15 includes a plate piece whose left and right side portions are bent downward and whose one side portion along the longitudinal direction is bent upward. The distance between the bent piece portions 15a on both the left and right sides is slightly larger than the distance between the fixed frames 24 of the upper paper discharge guide 14.
[0041]
The bent piece 15 a is provided with a pivot hole 29 and a mounting hole 30 side by side. The pivot hole 29 and the mounting hole 30 are provided with a pivot hole 25 and a screw provided in the fixed frame 24. It is provided at a position corresponding to the hole 26.
[0042]
Further, an inverted U-shaped notch process is performed on the lower edge of the bent piece portion 15 a, and this is referred to as a mating portion 31. The curvature radius of the curved surface portion of the mating portion 31 is formed to be the same as the radius of the shaft end portion 22a, like the receiving portion 27.
[0043]
The stopper 21 provided on the peeling claw support frame 15 corresponds to the upper surface portion of the bent piece portion 15a. The rising piece 15 b bent upward is a reinforcing piece of the peeling claw support frame 15.
[0044]
A mounting piece 15c to which a coil spring 32, which is an elastic body, is attached, is bent and formed integrally with the reinforcing piece 15b so as to be spaced apart from each other and at a predetermined interval. These mounting pieces 15c are provided corresponding to the mounting positions of the peeling claws 13 together with the positioning recesses 28, and are bent at a predetermined interval so that the peeling claws can be inserted into each other. Consists of folded pieces.
[0045]
Both ends of the coil spring 32 are fixedly attached to the attachment pieces 15c, and the coil portions are installed over the attachment pieces 15c. Although the coil spring 32 is used here as the elastic body, there is no problem even if it is a linear spring or a leaf spring.
[0046]
In particular, as shown in FIG. 6, when the second pivotal support 20 is the center, the turning locus of the coil spring 32 is larger than the radius Ra of the turning locus of the center of the peeling claw 13 (that is, the shaft 22). Is set to a small radius (Ra> Rb).
[0047]
Therefore, in a state where the coil spring 32 is engaged with the recessed portion 13 b of the peeling claw 13, the coil spring 32 extends from the free length, and the elastic force always acts on the peeling claw 13 so that the peeling claw is attached to the shaft 22. It is urged to rotate counterclockwise about the center.
[0048]
As shown in FIGS. 1 to 3, the left and right bent piece portions 15 a of the peeling claw support frame 15 are engaged with the outer surface side of the left and right fixed frames 24 of the upper discharge guide 14 in the assembled state. The pivot hole 29 and the mounting hole 30 provided in the bent piece portion 15a correspond to the pivot hole 25 and the screw hole 26 of the fixed frame 24, respectively.
[0049]
A pivot pin is inserted into the pivot hole 29 of the bent piece 15a and the pivot hole 25 of the fixed frame 24 together with the arm 17, and the second pivot section 20 is constituted by these.
[0050]
The fixing screw 16 as the fixing tool is screwed into the mounting hole 30 of the bent piece portion 15a and the screw hole 26 of the fixing frame 24, whereby the upper discharge guide 14 and the peeling claw support frame 15 are integrated. It has become.
[0051]
The integrated upper discharge guide 14 and the peeling claw support frame 15 are pivotally supported by the arm 17 via the second pivotal support portion 20, but the stopper 21 of the peeling claw support frame 15 is armed. As described above, the rotation in the clockwise direction in contact with the lower end edge of 17 is restricted.
[0052]
On the other hand, in the state where the upper paper discharge guide 14 and the peeling claw support frame 15 are assembled together, the side surfaces of the receiving portion 27 and the mating portion 31 are in close contact with each other, and the curved surface portions are directed in opposite directions. Thus, one perfect circular space is formed here.
[0053]
Both ends 22a of the shaft 22 are fitted and supported in the perfect circular space formed by the receiving portions 27 and the mating portions 31 on both the left and right side portions. A plurality of peeling claws 13 are loosely inserted into the shaft 22, and the peeling claws 13 are pivotally supported with respect to the shaft 22.
[0054]
A part of the peeling claw 13 is inserted into a positioning recess 28 provided in the upper paper discharge guide 14, so that the movement of the peeling claw 13 along the axis of the shaft 22 is restricted and positioned at a predetermined position.
[0055]
The tip claw portion 13 a of the peeling claw 13 protrudes from the upper paper discharge guide 14. Further, the upper end portion of the peeling claw 13 is inserted into the attachment piece 15 c of the peeling claw support frame 15, and the coil spring 32 stretched here is engaged with the recessed portion 13 b provided in the peeling claw 13.
[0056]
As described above, since the rotation trajectory radius Rb of the coil spring 32 is set smaller than the rotation trajectory radius Ra at the center of the peeling claw 13, the coil spring always extends beyond the free length.
[0057]
Accordingly, the elastic force of the coil spring 32 acts on the peeling claw 13 and urges the peeling claw to rotate counterclockwise about the shaft 22. This rotation direction coincides with the direction in which the tip claw portion 13a of the peeling claw 13 is in sliding contact with the heat roller 2 elastically.
[0058]
In this way, the peeling claw unit 10 is configured. Accordingly, the tip claw portion 13a of the peeling claw 13 always intervenes between the heat roller 2 and a copy paper (not shown) to peel the copy paper from the heat roller 2.
[0059]
Moreover, since each peeling claw 13 passes through one shaft 22, each peeling claw tip claw portion 13a contacts the heat roller 2 in substantially the same phase. Therefore, the peeling performance of each peeling claw 13 can be kept substantially the same.
[0060]
The peeling claw 13 with the tip claw portion 13a worn is replaced with a new one every predetermined usage period. The same applies to the case where the peeling claw tip claw portion 13a is mistakenly lost during the paper jam treatment.
[0061]
At this time, the fixing screw 16 is removed. Then, as shown in FIG. 4, the fixing of the upper discharge guide 14 to the peeling claw support frame 15 is released. Since the stopper 21 of the peeling claw support frame 15 is locked to the lower end edge of the arm 17, the posture of the peeling claw support frame 15 is continuously maintained. Therefore, the other end portion rotates in the clockwise direction.
[0062]
Accordingly, the upper paper discharge guide 14 rotates while the shaft 22 is supported by the receiving portion 27, and a gap is formed between the receiving portion 27 and the mating portion 31 of the peeling claw support frame 15. When the upper paper discharge guide 14 is rotated by a predetermined angle, the upper surface portion comes into contact with the lower edge of the bent piece portion 15a of the peeling claw support frame 15, and further rotation is restricted.
[0063]
As shown in FIG. 5, since a sufficient gap is formed between the receiving portion 27 of the upper paper discharge guide 14 and the mating portion 31 of the peeling claw support frame 15, the peeling claw 13 is taken out together with the shaft 22.
[0064]
At this time, since both end portions 22a of the shaft 22 are simply supported by the receiving portion 27 formed in the U shape of the upper discharge guide 14, the shaft 22 can be taken out from the receiving portion 27 very easily. it can.
[0065]
And each peeling nail | claw 13 is moved along the axial direction of the shaft 22, and it removes from the one end part 22a. Also at this time, since the peeling claw 13 is merely loosely inserted into the shaft 22 and does not particularly use a fixing member, it is easy to remove.
[0066]
A new peeling claw 13 is loosely inserted into the shaft 22, and the shaft 22 is engaged again with the receiving portion 27 of the upper paper discharge guide 14. Naturally, each peeling claw 13 is inserted into the positioning recess 28 of the upper paper discharge guide 14.
[0067]
Next, the upper discharge guide 14 is urged to rotate upward with a free end portion on the receiving portion 27 side. When the receiving portion 27 comes into contact with the mating portion 31 and the shaft 22 is pivotally supported again, the fixing screw 16 is screwed into the screw hole 26 through the mounting hole 30 and is discharged upward from the peeling claw support frame 15. The guides 14 are attached and fixed and integrated with each other.
[0068]
Such a mounting operation of the peeling claw 13 is the reverse of the removing operation described above, and all of them require extremely easy labor. Accordingly, the replacement of the peeling claw 13 can be improved in a very short time and without any trouble.
[0069]
A peeling claw 13A as shown in FIG. 7 may be used. Also in this embodiment, the radius Ra of the turning locus of the shaft 22 and the radius Rb of the turning locus of the coil spring 32 may be the same as the relationship described above. The configuration of the peeling claw 13A itself is the same as that described above except for the upper end portion.
[0070]
The upper end 13z of the peeling claw 13A is formed on a so-called downward inclined surface so as to have a predetermined angle θ with respect to the tangential direction of the coil spring 32. The angle θ is an angle that does not become larger than at least 90 ° (θ ≦ 90 °). Preferably, it may be in the range of 30 ° to 60 °.
[0071]
When attaching the peeling claw 13A to a predetermined portion, if the upper end portion 13z of the peeling claw contacts the coil spring 32, the upper end portion 13z is formed on the downward inclined surface, so that the coil spring 32 can be easily moved. The coil spring 32 is locked to the recessed portion 13b.
[0072]
That is, in the configuration of the peeling claw 13 described above, the upper end portion 13c of the peeling claw 13 cannot get over the coil spring 32 unless the coil spring 32 is greatly extended and deformed. It is not necessary to extend the coil spring 32 so much, and the attaching operation of the peeling claw 13A is further facilitated.
[0073]
【The invention's effect】
As described above, according to the first to tenth aspects of the invention, the means for supporting the peeling claw can be disassembled only by attaching / detaching the fixing means, and the peeling claw can be attached / detached therefrom. Accordingly, the replacement operation of the peeling claw is extremely facilitated, and the effect of improving the mounting accuracy is achieved.
