The suction unit 40 includes a suction chamber 41 and a suction drive unit 42 (see FIG. 6) connected to the suction chamber 41 and formed of a negative pressure source such as a vacuum pump.

吸着チャンバ４１は、払出部３０の払出ベルト３１が搬送部２０側に臨む部位において、払出ベルト３１の背面３１ｂ側に配置されている。吸着チャンバ４１は、払出ベルト３１の背面３１ｂ側に開口している。払出ベルト３１には、その表裏を貫通する貫通孔３１ｈが複数形成されている。吸着チャンバ４１内は負圧に保たれているため、吸着部４０は貫通孔３１ｈを通して払出ベルト３１に対して搬送部２０側に負圧を作用させることで、書類状荷物１００に吸着力を及ぼす。 The suction chamber 41 is arranged on the back surface 31b side of the payout belt 31 at a portion where the payout belt 31 of the payout portion 30 faces the transport portion 20 side. The suction chamber 41 is open on the back surface 31b side of the payout belt 31. The payout belt 31 is formed with a plurality of through holes 31h penetrating the front and back surfaces thereof. Since the inside of the suction chamber 41 is maintained at a negative pressure, the suction portion 40 exerts a suction force on the document-like luggage 100 by applying a negative pressure to the discharge belt 31 on the transport portion 20 side through the through hole 31h. ..

このような吸着部４０を有した払出部３０は、書類状荷物１００を、吸着部４０によって払出ベルト３１で吸着した状態で、方向Ｄｏの一方の側に払い出す。 The payout unit 30 having such a suction unit 40 pays out the document-like baggage 100 to one side of the direction Do in a state of being sucked by the suction unit 40 with the payout belt 31.

払出部３０は、払出ベルト３１に対して方向Ｄｏの一方の側に、一対の送り出しベルト３５をさらに備えている。これら送り出しベルト３５は、払出ベルト３１によって搬送部２０から方向Ｄｏに払い出された書類状荷物１００を挟み込んで、次工程に送り出す。 The payout unit 30 further includes a pair of payout belts 35 on one side of the direction Do with respect to the payout belt 31. These delivery belts 35 sandwich the document-like baggage 100 discharged from the transport unit 20 in the direction Do by the discharge belt 31 and deliver it to the next process.

センサ５０は、搬送部２０によって搬送される書類状荷物１００が予め定めた位置に到達したことを検知する。この実施形態において、センサ５０は、非接触センサ（第二センサ）５１と、接触センサ（第一センサ）５２と、を備える。これら非接触センサ５１、接触センサ５２は、例えば、吸着チャンバ４１において搬送部２０に臨む側に取り付けられている。 The sensor 50 detects that the document-like package 100 transported by the transport unit 20 has reached a predetermined position. In this embodiment, the sensor 50 includes a non-contact sensor (second sensor) 51 and a contact sensor (first sensor) 52. The non-contact sensor 51 and the contact sensor 52 are attached to, for example, the suction chamber 41 on the side facing the transport unit 20.

図７に示すように、非接触センサ５１は、搬送部２０によって搬送される書類状荷物１００が、吸着部４０から離間した予め定めた位置Ｐ１に到達した場合に、書類状荷物１００を検知する。つまり非接触センサ５１が書類状荷物１００を検知したとき、書類状荷物１００は吸着部４０に対して接触していない。
このような非接触センサ５１としては、例えば、赤外線センサ等のファイバセンサを用いることができる。ファイバセンサは、光電センサの光源に光ファイバを接続したもので、光源で発した光５１Ｂを、光ファイバの先端から対象物に向かって照射することで、対象物との距離を検出する。 As shown in FIG. 7, the non-contact sensor 51 detects the document-like package 100 when the document-like package 100 conveyed by the transfer unit 20 reaches a predetermined position P1 separated from the suction unit 40. .. That is, when the non-contact sensor 51 detects the document-like baggage 100, the document-like baggage 100 is not in contact with the suction portion 40.
As such a non-contact sensor 51, for example, a fiber sensor such as an infrared sensor can be used. The fiber sensor has an optical fiber connected to the light source of the photoelectric sensor, and detects the distance from the object by irradiating the light 51B emitted by the light source from the tip of the optical fiber toward the object.

図８に示すように、接触センサ５２は、書類状荷物１００が吸着部４０に接触又は近接する位置Ｐ２に到達した場合に書類状荷物１００を検知する。この実施形態で、接触センサ５２は、払出ベルト３１の上下にそれぞれ設けられている。これら上下二個一対の接触センサ５２で、書類状荷物１００が接触又は近接すると、書類状荷物１００は、払出ベルト３１に沿ってほぼ平行に位置して接触又は近接していることになる。なお接触センサ５２は一つのみ設けられていてもよい。 As shown in FIG. 8, the contact sensor 52 detects the document-like baggage 100 when the document-like baggage 100 reaches the position P2 in contact with or close to the suction portion 40. In this embodiment, the contact sensors 52 are provided above and below the payout belt 31, respectively. When the document-like baggage 100 comes into contact with or is close to each other by the pair of upper and lower contact sensors 52, the document-like baggage 100 is positioned substantially parallel to the payout belt 31 and is in contact with or close to each other. Only one contact sensor 52 may be provided.

図６に示すように、制御部６０は、非接触センサ５１及び接触センサ５２からの出力信号に基づいて、搬送ベルト駆動部２４、吸着駆動部４２、払出ベルト駆動部３３の動作を制御する。制御部６０は、センサ５０で、書類状荷物１００が予め定めた位置Ｐ１、Ｐ２に到達したことを検知した場合に、吸着部４０で書類状荷物１００を払出部３０に吸着させる。 As shown in FIG. 6, the control unit 60 controls the operations of the transport belt drive unit 24, the suction drive unit 42, and the payout belt drive unit 33 based on the output signals from the non-contact sensor 51 and the contact sensor 52. When the sensor 50 detects that the document baggage 100 has reached the predetermined positions P1 and P2, the control unit 60 sucks the document baggage 100 to the payout unit 30 by the suction unit 40.

制御部６０は、書類状荷物１００の搬送方向Ｄｍにおける厚さに応じて、薄物モード処理（第二モード処理）と、厚物モード処理（第一モード処理）と、を切り換える。制御部６０は、書類状荷物１００の搬送方向Ｄｍにおける厚みが、予め定めた値以下である場合に、「薄物モード処理」を実行する。制御部６０は、書類状荷物１００の厚みが予め定めた値よりも大きい場合に、「厚物モード処理」を実行する。 The control unit 60 switches between thin material mode processing (second mode processing) and thick material mode processing (first mode processing) according to the thickness of the document-like package 100 in the transport direction Dm. The control unit 60 executes the "thin material mode processing" when the thickness of the document-like package 100 in the transport direction Dm is equal to or less than a predetermined value. The control unit 60 executes the "thickness mode processing" when the thickness of the document-like baggage 100 is larger than a predetermined value.

薄物モード処理は、非接触センサ５１で書類状荷物１００を検知した場合に、吸着部４０で書類状荷物１００を払出部３０に吸着させる。すなわち、図７に示すように、薄物モード処理は、書類状荷物１００が吸着部４０から離間した予め定めた位置Ｐ１に到達して非接触センサ５１で検知された場合に、吸着部４０で書類状荷物１００を払出部３０に吸着させる。つまり、書類状荷物１００が吸着部４０に対して接触していない状態で、吸着部４０で書類状荷物１００を吸着する。すると、搬送方向Ｄｍの最前列に位置する１枚の書類状荷物１００のみが、吸着部４０に吸着される。
書類状荷物１００が薄い場合、書類状荷物１００は軽量であることが多い。したがって、このような軽量な書類状荷物１００は、吸着部４０から離間した状態から吸い寄せて吸着することができる。これにより、搬送方向Ｄｍの後方の書類状荷物１００が吸い寄せられるのを抑えて、最前列の書類状荷物１００のみを吸着して払い出すことができる。 In the thin object mode processing, when the document-like baggage 100 is detected by the non-contact sensor 51, the document-like baggage 100 is sucked by the suction unit 40 to the payout unit 30. That is, as shown in FIG. 7, in the thin material mode processing, when the document-like baggage 100 reaches a predetermined position P1 separated from the suction section 40 and is detected by the non-contact sensor 51, the document is detected by the suction section 40. The state baggage 100 is adsorbed on the payout unit 30. That is, the document-like baggage 100 is sucked by the suction part 40 in a state where the document-like baggage 100 is not in contact with the suction part 40. Then, only one document-like package 100 located in the front row in the transport direction Dm is sucked by the suction unit 40.
When the document baggage 100 is thin, the document baggage 100 is often lightweight. Therefore, such a lightweight document-like baggage 100 can be sucked and sucked from a state separated from the suction portion 40. As a result, it is possible to suppress the documentary baggage 100 behind the transport direction Dm from being sucked in, and to adsorb and pay out only the documentary baggage 100 in the front row.

厚物モード処理は、接触センサ５２で書類状荷物１００を検知した場合に、吸着部４０で書類状荷物１００を払出部３０に吸着させる。すなわち、図８に示すように、厚物モード処理は、書類状荷物１００が吸着部４０に接触又は近接した位置Ｐ２に到達して接触センサ５２で検知された場合に、吸着部４０で書類状荷物１００を払出部３０に吸着させる。つまり、厚物モード処理では、書類状荷物１００が吸着部４０に接触又は近接した状態で、吸着部４０で書類状荷物１００を吸着させる。すると、搬送方向Ｄｍの最前列に位置する１つの書類状荷物１００のみが、吸着部４０に吸着される。
書類状荷物１００が厚い場合、書類状荷物１００の重量も、より重いことが多い。したがって、より重量の大きい書類状荷物１００は、吸着部４０から離間した状態で吸着しようとしても、吸着部４０の吸着力が不足して書類状荷物１００を吸着するのが困難な場合がある。そこで、厚い書類状荷物１００の場合、書類状荷物１００が吸着部４０に接触又は近接した状態で吸着部４０に吸着させることで、書類状荷物１００を吸着部４０で確実に吸着して払い出すことができる。 In the thick material mode processing, when the document-like baggage 100 is detected by the contact sensor 52, the document-like baggage 100 is sucked by the suction unit 40 to the payout unit 30. That is, as shown in FIG. 8, in the thick mode processing, when the document-like baggage 100 reaches the position P2 in contact with or close to the suction unit 40 and is detected by the contact sensor 52, the document-like baggage is detected by the suction unit 40. The baggage 100 is adsorbed on the payout unit 30. That is, in the thick mode processing, the document-like baggage 100 is sucked by the suction part 40 in a state where the document-like baggage 100 is in contact with or close to the suction part 40. Then, only one document-like package 100 located in the front row in the transport direction Dm is sucked by the suction unit 40.
When the document baggage 100 is thick, the weight of the document baggage 100 is often heavier. Therefore, even if the heavier document-like luggage 100 tries to be sucked in a state of being separated from the suction portion 40, the suction force of the suction portion 40 may be insufficient and it may be difficult to suck the document-like luggage 100. Therefore, in the case of the thick document-like luggage 100, the document-like luggage 100 is attracted to the suction portion 40 in a state of being in contact with or close to the suction portion 40, so that the document-like luggage 100 is surely sucked and discharged by the suction portion 40. be able to.

ここで、薄物モード処理と厚物モード処理は、外部に設けられたモード切替部７０（図６参照）によって、切り換えることができる。モード切替部７０は、書類状荷物搬送装置１０のオペレータの判断によって操作される。オペレータは、払い出すべき書類状荷物１００の厚さに応じて、薄物モード処理と厚物モード処理とを選択し、モード切替部７０を操作する。
なお、モード切替部７０は、オペレータが手動操作するとは限らず、不図示のセンサ等によって、書類状荷物１００の厚み寸法を計測し、その結果に応じて、薄物モード処理と厚物モード処理とを自動的に選択するようにしてもよい。 Here, the thin material mode processing and the thick material mode processing can be switched by the mode switching unit 70 (see FIG. 6) provided externally. The mode switching unit 70 is operated at the discretion of the operator of the document-like luggage transport device 10. The operator selects thin mode processing and thick mode processing according to the thickness of the document baggage 100 to be paid out, and operates the mode switching unit 70.
The mode switching unit 70 is not always manually operated by the operator, but measures the thickness dimension of the document-like baggage 100 by a sensor (not shown) or the like, and according to the result, the thin mode processing and the thick mode processing are performed. May be automatically selected.

次に、上記したような書類状荷物搬送装置１０の運転方法について説明する。
書類状荷物搬送装置１０で、複数枚の書類状荷物１００を１枚ずつ払い出すには、まず、オペレータが、モード切替部７０によって、薄物モード処理又は厚物モード処理を選択する。
図９に示すように、制御部６０は、モード切替部７０で選択されたモード処理が、薄物モード処理であるか否かを判定する（ステップＳ１）。
その結果、選択されたモード処理が薄物モード処理である場合、制御部６０は、薄物モード処理Ｍ１に移行する。 Next, the operation method of the document-like luggage transport device 10 as described above will be described.
In order to pay out a plurality of document-like packages 100 one by one by the document-like baggage transfer device 10, the operator first selects thin-weight mode processing or thick-weight mode processing by the mode switching unit 70.
As shown in FIG. 9, the control unit 60 determines whether or not the mode processing selected by the mode switching unit 70 is the thin material mode processing (step S1).
As a result, when the selected mode processing is the thin material mode processing, the control unit 60 shifts to the thin material mode processing M1.

（薄物モード処理）
薄物モード処理Ｍ１では、まず、制御部６０は、搬送ベルト駆動部２４により搬送部２０の搬送ベルト２１を循環駆動させる（ステップＳ２）。搬送部２０の搬送部２０の搬送ベルト２１上には、オペレータによる手作業、あるいは各種の投入装置を用い、複数枚の書類状荷物１００を順次縦置きにして載置していく。搬送ベルト２１上に載置された書類状荷物１００は、縦置きされた状態で、搬送方向Ｄｍに沿って搬送されていく。 (Thin material mode processing)
In the thin material mode processing M1, first, the control unit 60 circulates and drives the transport belt 21 of the transport unit 20 by the transport belt drive unit 24 (step S2). A plurality of document-like packages 100 are sequentially placed vertically on the transport belt 21 of the transport unit 20 of the transport unit 20 by manual work by an operator or by using various loading devices. The document-like baggage 100 placed on the transport belt 21 is transported along the transport direction Dm in a vertically placed state.

制御部６０は、非接触センサ５１からの出力信号をモニタリングし、書類状荷物１００が予め定めた位置Ｐ１に到達して非接触センサ５１がＯＮになったか否かを判定する（ステップＳ３）。書類状荷物１００が位置Ｐ１に到達しておらず、非接触センサ５１からの出力信号がＯＦＦのままであれば、搬送ベルト２１を駆動させ続け、書類状荷物１００を搬送方向Ｄｍに沿って搬送する。 The control unit 60 monitors the output signal from the non-contact sensor 51 and determines whether or not the document-like baggage 100 has reached a predetermined position P1 and the non-contact sensor 51 has been turned on (step S3). If the document-like luggage 100 has not reached the position P1 and the output signal from the non-contact sensor 51 remains OFF, the transport belt 21 is continuously driven to transport the document-like luggage 100 along the transport direction Dm. do.

書類状荷物１００が位置Ｐ１に到達し、非接触センサ５１からの出力信号がＯＮに切り替わった場合、制御部６０は、搬送ベルト駆動部２４による搬送ベルト２１及び支持部材２２の駆動を停止させる（ステップＳ４）。これにより、書類状荷物１００の搬送方向Ｄｍに沿った移動が停止される。この状態で、書類状荷物１００は、払出ベルト３１から離間した状態で停止する。 When the document-like baggage 100 reaches the position P1 and the output signal from the non-contact sensor 51 is switched to ON, the control unit 60 stops the drive of the transfer belt 21 and the support member 22 by the transfer belt drive unit 24 ( Step S4). As a result, the movement of the documentary baggage 100 along the transport direction Dm is stopped. In this state, the document-like baggage 100 stops in a state of being separated from the payout belt 31.

次に、制御部６０は、吸着駆動部４２により、吸着部４０で、位置Ｐ１において搬送方向Ｄｍの最前列に位置する書類状荷物１００を吸着する（ステップＳ５）。 Next, the control unit 60 sucks the document-like luggage 100 located in the front row in the transport direction Dm at the position P1 at the suction unit 40 by the suction drive unit 42 (step S5).

続いて、制御部６０は、払出ベルト駆動部３３により、吸着部４０で書類状荷物１００を吸着したまま、払出ベルト３１を循環駆動する（ステップＳ６）。これにより、書類状荷物１００が、搬送方向Ｄｍの搬送方向に交差する方向Ｄｏに払い出される。払い出された書類状荷物１００は、一対の送り出しベルト３５、３５に挟まれて、次工程に送り出される。 Subsequently, the control unit 60 circulates and drives the payout belt 31 while the document-like baggage 100 is sucked by the suction unit 40 by the payout belt drive unit 33 (step S6). As a result, the document-like package 100 is paid out in the direction Do that intersects the transport direction of the transport direction Dm. The paid-out document-like baggage 100 is sandwiched between a pair of delivery belts 35 and 35 and sent out to the next process.

この後、制御部６０は、書類状荷物搬送装置１０の薄物モード処理での運転が終了したか否かを判定する（ステップＳ７）。制御部６０は、薄物モード処理での運転が終了しない限り、ステップＳ２に戻って処理を続行する。また、書類状荷物搬送装置１０の薄物モード処理での運転が終了した場合、制御部６０における一連の処理を停止する。 After that, the control unit 60 determines whether or not the operation of the document-like luggage transport device 10 in the thin material mode processing is completed (step S7). The control unit 60 returns to step S2 and continues the process unless the operation in the thin material mode process is completed. Further, when the operation of the document-like luggage transport device 10 in the thin material mode processing is completed, the series of processing in the control unit 60 is stopped.

（厚物モード処理）
また、制御部６０は、ステップＳ１において、モード切替部７０で選択されたモード処理が厚物モード処理であった場合、ステップＳ１２以降の厚物モード処理Ｍ２に移行する。厚物モード処理Ｍ２では、まず、制御部６０は、搬送ベルト駆動部２４により搬送部２０の搬送ベルト２１を循環駆動させる（ステップＳ１２）。搬送部２０の搬送部２０の搬送ベルト２１上には、オペレータによる手作業、あるいは各種の投入装置を用い、複数枚の書類状荷物１００を順次縦置きにして載置していく。搬送ベルト２１上に載置された書類状荷物１００は、縦置きされた状態で、搬送方向Ｄｍに沿って搬送されていく。 (Thick mode processing)
Further, when the mode process selected by the mode switching unit 70 is the thick mode process in step S1, the control unit 60 shifts to the thick mode process M2 after step S12. In the thick material mode processing M2, first, the control unit 60 circulates and drives the transport belt 21 of the transport unit 20 by the transport belt drive unit 24 (step S12). A plurality of document-like packages 100 are sequentially placed vertically on the transport belt 21 of the transport unit 20 of the transport unit 20 by manual work by an operator or by using various loading devices. The document-like baggage 100 placed on the transport belt 21 is transported along the transport direction Dm in a vertically placed state.

制御部６０は、一対の接触センサ５２からの出力信号をモニタリングし、一対の接触センサ５２の双方がＯＮになったか否かを判定する（ステップＳ１３）。書類状荷物１００が位置Ｐ２に到達しておらず、一対の接触センサ５２からの出力信号がＯＦＦのままであれば、搬送ベルト２１を駆動させ続け、書類状荷物１００を搬送方向Ｄｍに沿って搬送する。 The control unit 60 monitors the output signals from the pair of contact sensors 52 and determines whether or not both of the pair of contact sensors 52 are turned on (step S13). If the document-like luggage 100 has not reached the position P2 and the output signals from the pair of contact sensors 52 remain OFF, the transport belt 21 is continuously driven and the document-like luggage 100 is moved along the transport direction Dm. Transport.

書類状荷物１００が、一対の接触センサ５２の双方に接触又は近接して予め定めた位置Ｐ２に到達すると、接触センサ５２からの出力信号がＯＮに切り替わる。接触センサ５２の出力信号がＯＮになったことを検知した場合、制御部６０は、搬送ベルト駆動部２４による搬送ベルト２１及び支持部材２２の駆動を停止させる（ステップＳ１４）。これにより、書類状荷物１００の搬送方向Ｄｍに沿った移動が停止される。この状態で、書類状荷物１００は、一対の接触センサ５２の双方に接触又は近接し、払出ベルト３１に沿っている。 When the document-like baggage 100 comes into contact with or is close to both of the pair of contact sensors 52 and reaches a predetermined position P2, the output signal from the contact sensor 52 is switched to ON. When it is detected that the output signal of the contact sensor 52 is turned on, the control unit 60 stops the drive of the transfer belt 21 and the support member 22 by the transfer belt drive unit 24 (step S14). As a result, the movement of the documentary baggage 100 along the transport direction Dm is stopped. In this state, the document baggage 100 is in contact with or close to both of the pair of contact sensors 52 and is along the payout belt 31.

次に、制御部６０は、吸着駆動部４２により、吸着部４０で、位置Ｐ２において搬送方向Ｄｍの最前列に位置する書類状荷物１００を吸着する（ステップＳ１５）。 Next, the control unit 60 sucks the document-like luggage 100 located in the front row in the transport direction Dm at the position P2 at the suction unit 40 by the suction drive unit 42 (step S15).

続いて、制御部６０は、払出ベルト駆動部３３により、吸着部４０で書類状荷物１００を吸着したまま、払出ベルト３１を循環駆動する（ステップＳ１６）。これにより、書類状荷物１００が、搬送方向Ｄｍの搬送方向に交差する方向Ｄｏに払い出される。払い出された書類状荷物１００は、一対の送り出しベルト３５、３５に挟まれて、次工程に送り出される。 Subsequently, the control unit 60 circulates and drives the payout belt 31 by the payout belt drive unit 33 while the document-like baggage 100 is sucked by the suction unit 40 (step S16). As a result, the document-like package 100 is paid out in the direction Do that intersects the transport direction of the transport direction Dm. The paid-out document-like baggage 100 is sandwiched between a pair of delivery belts 35 and 35 and sent out to the next process.

この後、制御部６０は、書類状荷物搬送装置１０の厚物モード処理での運転が終了したか否かを判定する（ステップＳ１７）。制御部６０は、厚物モード処理での運転が終了しない限り、ステップＳ１２に戻って処理を続行する。また、書類状荷物搬送装置１０の厚物モード処理での運転が終了した場合、制御部６０における一連の処理を停止する。 After that, the control unit 60 determines whether or not the operation of the document-like luggage transport device 10 in the thick mode processing is completed (step S17). The control unit 60 returns to step S12 and continues the process unless the operation in the thick mode process is completed. Further, when the operation of the document-like luggage transport device 10 in the thick mode processing is completed, the series of processing in the control unit 60 is stopped.

このような書類状荷物搬送装置１０では、搬送部２０によって搬送される書類状荷物１００が、予め定めた位置Ｐ１、Ｐ２に到達すると、センサ５０により書類状荷物１００が検知される。すると、制御部６０により、書類状荷物１００が吸着部４０で払出部３０に吸着される。これにより、書類状荷物１００を１枚ずつ吸着した状態で、払出部３０によって、搬送部２０による搬送方向Ｄｍと交差する方向Ｄｏに払い出すことができる。
したがって、書類状荷物搬送装置１は、複数枚の書類状荷物１００から、書類状荷物１００を１枚ずつ取り出す動作を、より高い信頼性で実現することができる。 In such a document-like luggage transport device 10, when the document-like luggage 100 transported by the transport unit 20 reaches predetermined positions P1 and P2, the sensor 50 detects the document-like luggage 100. Then, the control unit 60 attracts the document-like package 100 to the payout unit 30 by the suction unit 40. As a result, the document-like packages 100 can be paid out one by one by the payout unit 30 in the direction Do intersecting the transport direction Dm by the transport unit 20.
Therefore, the document-like luggage transport device 1 can realize the operation of taking out the document-like luggage 100 one by one from the plurality of document-like luggage 100 with higher reliability.

また、センサ５０は、搬送部２０によって搬送される書類状荷物１００が、吸着部４０から離間した予め定めた位置Ｐ１に到達した場合に、書類状荷物１００を検知する非接触センサ５１を備えている。これにより、書類状荷物１００が吸着部４０に対して接触していない状態で、吸着部４０が書類状荷物１００を吸着する。その結果、搬送方向Ｄｍ最前列に位置する１枚の書類状荷物１００のみが、吸着部４０に吸着される。これにより、搬送方向Ｄｍ最前列よりも搬送方向Ｄｍ後方に位置する他の書類状荷物１００が、吸着部４０に吸着される最前列の書類状荷物１００とともに払出部３０によって払い出されることを抑制できる。 Further, the sensor 50 includes a non-contact sensor 51 that detects the document-like package 100 when the document-like package 100 transported by the transfer unit 20 reaches a predetermined position P1 separated from the suction unit 40. There is. As a result, the suction unit 40 sucks the document baggage 100 in a state where the document baggage 100 is not in contact with the suction unit 40. As a result, only one document-like package 100 located in the front row in the transport direction Dm is sucked by the suction unit 40. As a result, it is possible to prevent the other document-like luggage 100 located behind the front row in the transport direction Dm from being paid out by the payout unit 30 together with the document-like luggage 100 in the front row that is sucked by the suction unit 40. ..

また、センサ５０は、書類状荷物１００が吸着部４０に接触又は近接した場合に書類状荷物１００を検知する接触センサ５２を備える。
さらに、制御部６０は、非接触センサ５１で書類状荷物１００を検知した場合に、吸着部４０で書類状荷物１００を払出部３０に吸着させる薄物モード処理Ｍ１と、接触センサ５２で書類状荷物１００を検知した場合に、吸着部４０で書類状荷物１００を払出部３０に吸着させる厚物モード処理Ｍ２と、を切替可能である。これにより、書類状荷物１００の厚さや重量等に応じて、薄物モード処理Ｍ１と厚物モード処理Ｍ２とを切り換えることで、それぞれの書類状荷物１００に適した状態で吸着部４０による書類状荷物１００の吸着を行うことができる。 Further, the sensor 50 includes a contact sensor 52 that detects the document-like baggage 100 when the document-like baggage 100 comes into contact with or is close to the suction unit 40.
Further, when the non-contact sensor 51 detects the document-like baggage 100, the control unit 60 uses the suction unit 40 to suck the document-like baggage 100 to the payout unit 30, and the contact sensor 52 to suck the document-like baggage 100 to the payout unit 30. When 100 is detected, it is possible to switch between the thick mode processing M2 in which the document-like baggage 100 is adsorbed on the payout unit 30 by the suction unit 40. As a result, by switching between the thin mode processing M1 and the thick mode processing M2 according to the thickness, weight, etc. of the documentary luggage 100, the documentary luggage by the suction unit 40 in a state suitable for each documentary luggage 100. 100 adsorptions can be performed.

加えて、制御部６０は、書類状荷物１００の搬送方向Ｄｍにおける厚みが、予め定めた値以下である場合に薄物モード処理Ｍ１を実行し、書類状荷物１００の厚みが予め定めた値よりも大きい場合に厚物モード処理Ｍ２を実行する。
このように、薄い書類状荷物１００の場合に、薄物モード処理によって、書類状荷物１００が吸着部４０から離間した状態で吸着することで、最前列の書類状荷物１００のみを吸着して払い出すことができる。また、書類状荷物１００が厚い場合に、厚物モード処理を実行することで、吸着部４０に接触又は近接した状態で書類状荷物１００を吸着部４０に吸着させることで、厚い書類状荷物１００を吸着部４０で確実に吸着して払い出すことができる。 In addition, the control unit 60 executes the thin material mode processing M1 when the thickness of the document-like baggage 100 in the transport direction Dm is equal to or less than a predetermined value, and the thickness of the document-like baggage 100 is larger than the predetermined value. If it is large, the thick mode process M2 is executed.
In this way, in the case of the thin document baggage 100, by the thin object mode processing, the document baggage 100 is adsorbed in a state of being separated from the suction portion 40, so that only the document baggage 100 in the front row is sucked and discharged. be able to. Further, when the document-like luggage 100 is thick, by executing the thick material mode processing, the document-like luggage 100 is attracted to the suction portion 40 in a state of being in contact with or close to the suction portion 40, so that the thick document-like luggage 100 is attached. Can be reliably adsorbed by the adsorption unit 40 and discharged.

また、制御部６０は、薄物モード処理Ｍ１では、書類状荷物１００が吸着部４０から離間した位置Ｐ１に到達して非接触センサ５１で検知された場合に、搬送ベルト２１及び支持部材２２の搬送方向Ｄｍへの移動を停止させるようにした。これにより、薄物モード処理Ｍ１では、書類状荷物１００が吸着部４０から離れた状態で、吸着部４０による吸着を行うことができる。これにより、最前列の１枚の薄い書類状荷物１００のみを吸い寄せて吸着することができる。
また、制御部６０は、厚物モード処理Ｍ２では、書類状荷物１００が吸着部４０に接触又は近接して接触センサ５２で検知された場合に、搬送ベルト２１及び支持部材２２の搬送方向Ｄｍへの移動を停止させるようにした。これにより、厚物モード処理Ｍ２では、書類状荷物１００が吸着部４０に接触又は近接するまで、搬送ベルト２１及び支持部材２２によって書類状荷物１００を移動させる。これにより、厚い書類状荷物１００であっても、吸着部４０で確実に吸着させることができる。 Further, in the thin material mode processing M1, the control unit 60 conveys the transport belt 21 and the support member 22 when the document-like luggage 100 reaches the position P1 separated from the suction portion 40 and is detected by the non-contact sensor 51. The movement in the direction Dm is stopped. As a result, in the thin material mode processing M1, the document-like baggage 100 can be sucked by the suction unit 40 in a state of being separated from the suction unit 40. As a result, only one thin document-like baggage 100 in the front row can be attracted and adsorbed.
Further, in the thick mode processing M2, the control unit 60 moves to the transport direction Dm of the transport belt 21 and the support member 22 when the document-like baggage 100 comes into contact with or is close to the suction section 40 and is detected by the contact sensor 52. Changed to stop the movement of. As a result, in the thick mode processing M2, the document-like luggage 100 is moved by the transport belt 21 and the support member 22 until the document-like luggage 100 comes into contact with or approaches the suction portion 40. As a result, even a thick document-like baggage 100 can be reliably adsorbed by the suction unit 40.

また、書類状荷物搬送装置１０は、外部から、薄物モード処理Ｍ１及び厚物モード処理Ｍ２を選択するモード切替部７０をさらに備えている。これにより、書類状荷物搬送装置１０のオペレータの判断によって、または自動的に、払い出すべき書類状荷物１００の厚さに応じて、薄物モード処理Ｍ１と厚物モード処理Ｍ２とを選択し、書類状荷物１００の払出処理を行うことができる。 Further, the document-like luggage transport device 10 further includes a mode switching unit 70 that selects the thin mode processing M1 and the thick mode processing M2 from the outside. As a result, the thin mode processing M1 and the thick mode processing M2 are selected according to the judgment of the operator of the document-like baggage transfer device 10 or automatically according to the thickness of the document-like baggage 100 to be paid out, and the document is selected. It is possible to process the withdrawal of the state baggage 100.
