〔第１の実施形態〕
図１に、本発明を好適に実施した第１の実施形態に係るスタッカの構成を示す。
スタッカ１００は、不図示の装置（複写機など）から排出された用紙を矢印Ａ方向から導入する。導入された用紙は、用紙搬送路Ｌを通して、用紙積載空間内にセットされているスタックトレイ１０１上に用紙を排出して積載する用紙積載装置である。 [First Embodiment]
FIG. 1 shows the configuration of a stacker according to a first embodiment in which the present invention is suitably implemented.
The stacker 100 introduces paper discharged from an unillustrated apparatus (such as a copying machine) from the direction of arrow A. The introduced paper is a paper stacking device that discharges and stacks paper on the stack tray 101 set in the paper stacking space through the paper transport path L.

スタックトレイ１０１は、昇降可能なエレベータ部材１０２上に載置されている。エレベータ部材１０２の四隅は、計４本のタイミングベルト１０３によって吊られており、それぞれのタイミングベルト１０３は、対応する計四つのタイミングプーリ１０４に巻き付けられている。それらのタイミングプーリ１０４は、ウォームギヤ１０５と複数のギヤとから構成されるギヤ列１０６によって連係されており、トレイ昇降モータ１０７の駆動力によって同期的に回転されることによって、スタックトレイ１０１とともにエレベータ部材１０２を昇降させる。動力伝達系がウォームギヤ１０５を介しているため、スタックトレイ１０１を一定位置に保つことができる。すなわち、スタックトレイ１０１が自重で降下してしまうことはない。   The stack tray 101 is placed on an elevator member 102 that can be raised and lowered. The four corners of the elevator member 102 are suspended by a total of four timing belts 103, and each timing belt 103 is wound around a corresponding four timing pulleys 104. These timing pulleys 104 are linked by a gear train 106 composed of a worm gear 105 and a plurality of gears, and are rotated together with the stack tray 101 by the driving force of the tray lifting / lowering motor 107 to thereby move the elevator member together with the stack tray 101. 102 is moved up and down. Since the power transmission system is via the worm gear 105, the stack tray 101 can be kept at a fixed position. That is, the stack tray 101 is not lowered by its own weight.

スタックトレイ１０１に用紙を積載し終えると、エレベータ部材１０２は最下位置まで降下し、台車１０８上に載置される。これにより、スタックトレイ１０１上に積載した用紙は、台車１０８とともにスタッカ１００から搬出可能な状態となる。   When the stacking of sheets on the stack tray 101 is completed, the elevator member 102 is lowered to the lowest position and placed on the carriage 108. As a result, the sheets stacked on the stack tray 101 can be unloaded from the stacker 100 together with the carriage 108.

用紙搬送ローラ１０９には、ばねによって付勢された従動ローラ１１０が圧接されており、これらのローラ１０９、１１０の間に用紙がニップされる。用紙搬送ローラ１０９が駆動されることによって、不図示の装置（複写機など）から排出されてくる用紙を搬送する。   A driven roller 110 biased by a spring is pressed against the paper transport roller 109, and the paper is nipped between these rollers 109 and 110. When the paper transport roller 109 is driven, the paper discharged from a device (not shown) (such as a copying machine) is transported.

スタッカ１００内には、スタックトレイ１０１の用紙積載面と間隔を空けて、用紙揃え装置として図２に示すようなパドルが設置されている。本実施形態に係るパドルは、第１の軸部と第２の軸部とが直列に連結される構成である。第１の軸部の一端にはギヤが取り付けられ、ベルトを介してモータの駆動力が伝達される。   In the stacker 100, a paddle as shown in FIG. 2 is installed as a paper aligning device with a gap from the paper stacking surface of the stack tray 101. The paddle according to the present embodiment has a configuration in which a first shaft portion and a second shaft portion are connected in series. A gear is attached to one end of the first shaft portion, and the driving force of the motor is transmitted via the belt.

図３に示すように、第１の軸部の他端には、軸と垂直にピン１が装着されており、ピン１の先端部が軸から突出して突起を形成している。第２の軸部の一端には、第１の軸部の端部を挿入可能な穴２と、溝３とを備えた軸受部４が設けられている。   As shown in FIG. 3, a pin 1 is attached to the other end of the first shaft portion perpendicularly to the shaft, and a tip portion of the pin 1 protrudes from the shaft to form a protrusion. At one end of the second shaft portion, a bearing portion 4 including a hole 2 into which the end portion of the first shaft portion can be inserted and a groove 3 is provided.

図４に示すように、第２の軸部の他端には、ワッシャ６ａとＥリング（Ｅ型止め輪）６ｂとでバネ７が固定されている。バネ７は、第２の軸部を一端側へ付勢する。第２の軸部の他端部は、軸が回転自在となるようにベアリング等を介して支持されている。   As shown in FIG. 4, a spring 7 is fixed to the other end of the second shaft portion with a washer 6a and an E-ring (E-type retaining ring) 6b. The spring 7 biases the second shaft portion toward one end. The other end portion of the second shaft portion is supported via a bearing or the like so that the shaft is rotatable.

第２の軸部の所定の位置には、用紙等のシートの搬送方向位置を揃えるためのフィンが設置されている。   Fins are arranged at predetermined positions of the second shaft portion to align the position in the conveyance direction of sheets such as paper.

バネを押し縮めた状態で第１の軸部に装着されたピン１を第２の軸部に設けられた軸受部４が備える溝３に嵌合させてから、バネ７を開放することにより、第２の軸部の軸受部４が第１の軸部に押し付けられ、第１の軸部と第２の軸部とが結合する。
第１の軸部と第２の軸部とが結合した状態においては、不図示のモータからの駆動力は、ピン１と溝３との嵌合によって第１の軸部から第２の軸部へと伝えられる。よって、第２の軸部は第１の軸部と共に回転する。 By fitting the pin 1 mounted on the first shaft portion in a state where the spring is compressed into the groove 3 provided in the bearing portion 4 provided on the second shaft portion, the spring 7 is opened, The bearing portion 4 of the second shaft portion is pressed against the first shaft portion, and the first shaft portion and the second shaft portion are coupled.
In a state in which the first shaft portion and the second shaft portion are coupled, the driving force from the motor (not shown) is generated by the fitting of the pin 1 and the groove 3 to the second shaft portion from the first shaft portion. To be told. Therefore, the second shaft portion rotates together with the first shaft portion.

バネ７を押し縮めることにより、ピン１は溝３から外れ、第１の軸部と第２の軸部との結合が解除される。結合を解除することにより、第２の軸部のみを取り外すことが可能となる。   By pressing and contracting the spring 7, the pin 1 is removed from the groove 3, and the coupling between the first shaft portion and the second shaft portion is released. By releasing the coupling, it is possible to remove only the second shaft portion.

このように、本実施形態に係るパドルは、第１の軸部に取り付けられるギヤやベルトを外さなくとも第２の軸部のみを取り外すことができる。   Thus, the paddle according to the present embodiment can remove only the second shaft portion without removing the gear or belt attached to the first shaft portion.

なお、個々では第１の軸部の他端にピンを装着する構成を例としたが、第１の軸部と一体の突起としても良い。ただし、加工性の面では、第１の軸部に貫通穴を設けピンを挿入する方が容易である。   In addition, although the structure which attaches a pin to the other end of a 1st axial part was made into an example individually, it is good also as a protrusion integral with a 1st axial part. However, in terms of workability, it is easier to insert a pin by providing a through hole in the first shaft portion.

〔第２の実施形態〕
本発明を好適に実施した第２の実施形態について説明する。スタッカの構成は第１の実施形態と同様である。
図５に、本実施形態に係るパドルの第１の軸部と第２の軸部との結合部分の構造を示す。第１の軸部の端部には雌ねじ９が形成されており、第２の軸部の端部には雄ねじ８が形成されている。なお、これらのねじは、モータからの駆動力でパドルが回転する際に締まる向きに形成されている。 [Second Embodiment]
A second embodiment in which the present invention is suitably implemented will be described. The configuration of the stacker is the same as that of the first embodiment.
FIG. 5 shows a structure of a coupling portion between the first shaft portion and the second shaft portion of the paddle according to the present embodiment. A female screw 9 is formed at the end of the first shaft portion, and a male screw 8 is formed at the end of the second shaft portion. These screws are formed in a direction to be tightened when the paddle is rotated by the driving force from the motor.

第１の軸部の不図示となる側の端部の構成は、第１の実施形態と同様であり、ギヤが取り付けられ、ベルトを介してモータの駆動力が伝達される。一方、第２の軸部の不図示となる側の端部の構成は、第１の実施形態とは異なっており、ワッシャやＥリング、バネは設置されておらず、単純にベアリングによって回動自在に支持されている。   The configuration of the end portion of the first shaft portion (not shown) is the same as that of the first embodiment, and a gear is attached and the driving force of the motor is transmitted via the belt. On the other hand, the configuration of the end portion of the second shaft portion (not shown) is different from that of the first embodiment, and no washer, E-ring, or spring is installed, and it is simply rotated by a bearing. It is supported freely.

バネを押し縮めた状態で第１の軸部と第２の軸部とを突き合わせ、ねじ込み方向に回転させることにより、第１の軸部と第２の軸部とが結合する。第１の軸部と第２の軸部とが結合した状態においては、不図示のモータからの駆動力は、雄ねじ９と雌ねじ８とのねじ止めによって第１の軸部から第２の軸部へと伝えられる。よって、第２の軸部は第１の軸部とともに回転する。   The first shaft portion and the second shaft portion are brought into contact with each other in a state in which the spring is compressed and rotated in the screwing direction, so that the first shaft portion and the second shaft portion are coupled. In a state where the first shaft portion and the second shaft portion are coupled, the driving force from the motor (not shown) is driven from the first shaft portion to the second shaft portion by screwing the male screw 9 and the female screw 8. To be told. Therefore, the second shaft portion rotates together with the first shaft portion.

第２の軸部をねじ込み方向と逆方向に回転させることにより、雄ねじ９は雌ねじ８から抜け出て第１の軸部と第２の軸部との結合が解除される。結合を解除することにより、第２の軸部のみを取り外すことが可能となる。   By rotating the second shaft portion in the direction opposite to the screwing direction, the male screw 9 comes out of the female screw 8 and the coupling between the first shaft portion and the second shaft portion is released. By releasing the coupling, it is possible to remove only the second shaft portion.

本実施形態においても、第１の軸部に取り付けられるギヤやベルトを外さなくとも第２の軸部のみを取り外すことができる。   Also in this embodiment, it is possible to remove only the second shaft portion without removing the gear or belt attached to the first shaft portion.

〔第３の実施形態〕
本発明を好適に実施した第３の実施形態について説明する。スタッカの構成は第１の実施形態と同様である
図６に、本実施形態に係るパドルの第１の軸部と第２の軸部との結合部分の構造を示す。第１の軸の端部には、側面視では軸心を含む部分が突出した凸状となるように突起１２が形成されており、第２の軸の端部には、第１の軸の端部とは逆に側面視では軸心を含む部分が窪んだ凹状となるように溝１０が形成されている。溝１０及び突起１２にはそれぞれに直交するように貫通穴１１、１３が形成されている。 [Third Embodiment]
A third embodiment in which the present invention is preferably implemented will be described. The configuration of the stacker is the same as that of the first embodiment. FIG. 6 shows the structure of the connecting portion between the first shaft portion and the second shaft portion of the paddle according to this embodiment. A protrusion 12 is formed at the end of the first shaft so as to have a convex shape in which a portion including the axis is projected in a side view, and at the end of the second shaft, the protrusion of the first shaft is formed. Contrary to the end portion, the groove 10 is formed so as to have a concave shape in which a portion including the axial center is recessed in a side view. Through holes 11 and 13 are formed in the groove 10 and the protrusion 12 so as to be orthogonal to each other.

第１の軸部及び第２の軸部の不図示となる側の端部の構成は、第２の実施形態と同様である。   The configuration of the end portions of the first shaft portion and the second shaft portion on the side (not shown) is the same as that of the second embodiment.

突起１２と溝１０とを嵌合させ、貫通穴１１、１３を介して共締めすることにより、第１の軸部と第２の軸部とが結合する。第１の軸部と第２の軸部とが結合した状態においては、不図示のモータからの駆動力は、貫通穴１１、１３に締結されたねじ１４によって第１の軸部から第２の軸部へと伝えられる。よって、第２の軸部は第１の軸部とともに回転する。   The first shaft portion and the second shaft portion are coupled by fitting the protrusion 12 and the groove 10 and fastening them together via the through holes 11 and 13. In a state where the first shaft portion and the second shaft portion are coupled, the driving force from the motor (not shown) is transmitted from the first shaft portion to the second shaft 14 by the screws 14 fastened to the through holes 11 and 13. It is transmitted to the shaft. Therefore, the second shaft portion rotates together with the first shaft portion.

貫通穴１１、１３に締結されたねじ１４を取り外すことにより、第１の軸部と第２の軸部との結合は解除される。結合を解除することにより第２の軸部のみを取り外すことが可能な状態となる。   By removing the screw 14 fastened to the through holes 11 and 13, the coupling between the first shaft portion and the second shaft portion is released. By releasing the coupling, only the second shaft portion can be removed.

本実施形態においても、第１の軸部に取り付けられるギヤやベルトを外さなくとも第２の軸部のみを取り外すことができる。   Also in this embodiment, it is possible to remove only the second shaft portion without removing the gear or belt attached to the first shaft portion.

〔第４の実施形態〕
本発明を好適に実施した第４の実施形態について説明する。スタッカの構成は第１の実施形態と同様である。
図７に、本実施形態に係るパドルの第１の軸部と第２の軸部との結合部分の構造を示す。第１の軸部の端部には凹部１５が形成されており、第２の軸部の端部には凸部１６が形成されている。凸部１６の突起部分と凹部１５の開口部分とは、同一の断面形状となっており、凸部１６と凹部１５とを嵌合可能となっている。これらの断面形状は非円形であれば任意であるが、凹凸が噛み合って嵌合する断面形状であることが好ましい。すなわち、図８に示すように、第１の軸部と第２の軸部とをセレーション及びリブのように結合させる形状であることが好ましい。 [Fourth Embodiment]
A fourth embodiment in which the present invention is preferably implemented will be described. The configuration of the stacker is the same as that of the first embodiment.
FIG. 7 shows a structure of a coupling portion between the first shaft portion and the second shaft portion of the paddle according to the present embodiment. A concave portion 15 is formed at the end portion of the first shaft portion, and a convex portion 16 is formed at the end portion of the second shaft portion. The protruding portion of the convex portion 16 and the opening portion of the concave portion 15 have the same cross-sectional shape, and the convex portion 16 and the concave portion 15 can be fitted. These cross-sectional shapes are arbitrary as long as they are non-circular, but are preferably cross-sectional shapes in which concaves and convexes mesh and fit. That is, as shown in FIG. 8, it is preferable that the first shaft portion and the second shaft portion are joined together like serrations and ribs.

第１の軸部及び第２の軸部の不図示となる側の端部の構成は、第１の実施形態と同様である。すなわち、第２の軸部の不図示となる側の端部にはワッシャとＥリング（Ｅ型止め輪）とでバネが固定されており、バネは、第２の軸部を図示する側の端部方向へ付勢している。   The configuration of the end portions of the first shaft portion and the second shaft portion that are not shown in the drawing is the same as that of the first embodiment. That is, a spring is fixed to the end of the second shaft portion (not shown) by a washer and an E-ring (E-type retaining ring). It is biased toward the end.

バネを押し縮めた状態で第１の軸部の凹部１５を第２の軸部に設けられた凸部１６に突き合わせてから、バネを開放することにより、凸部１６が凹部１５に挿入され、第１の軸部と第２の軸部とが結合する。
凸部１６及び凹部１５の断面形状は非円形であり、これらには半径方向で重なり合う部分が存在するため、第１の軸部と第２の軸部とが結合した状態においては、不図示のモータからの駆動力は、第１の軸部から第２の軸部へと伝えられる。よって、第２の軸部は第１の軸部と共に回転する。 After the spring 15 is pressed and contracted, the concave portion 15 of the first shaft portion is abutted against the convex portion 16 provided on the second shaft portion, and then the spring is released, whereby the convex portion 16 is inserted into the concave portion 15, The first shaft portion and the second shaft portion are coupled.
The cross-sectional shapes of the convex portion 16 and the concave portion 15 are non-circular, and since there are portions that overlap in the radial direction, they are not shown in the state where the first shaft portion and the second shaft portion are coupled. The driving force from the motor is transmitted from the first shaft portion to the second shaft portion. Therefore, the second shaft portion rotates together with the first shaft portion.

バネを押し縮めることにより、凸部１６は凹部１５から外れ、第１の軸部と第２の軸部との結合が解除される。結合を解除することにより、第２の軸部のみを取り外すことが可能となる。   By pressing and contracting the spring, the convex portion 16 is detached from the concave portion 15 and the coupling between the first shaft portion and the second shaft portion is released. By releasing the coupling, it is possible to remove only the second shaft portion.

本実施形態においても、第１の軸部に取り付けられるギヤやベルトを外さなくとも第２の軸部のみを取り外すことができる。   Also in this embodiment, it is possible to remove only the second shaft portion without removing the gear or belt attached to the first shaft portion.

なお、上記各実施形態は本発明の好適な実施の一例であり、本発明はこれらに限定されることはなく、様々な変形が可能である。   Each of the above embodiments is an example of a preferred embodiment of the present invention, and the present invention is not limited to these, and various modifications are possible.
