以下、図面に示す実施例により本発明を説明する。図１は本発明の一実施例に係るエアコンベヤの全体の構成を示す側面図であり、このエアコンベヤ（全体として符号２で示す）は、上方側の水平区間２Ａと下方側の水平区間２Ｃとの間を傾斜区間２Ｂによって接続して、上方から下方へ容器４を搬送するようになっている。   Hereinafter, the present invention will be described with reference to embodiments shown in the drawings. FIG. 1 is a side view showing the overall structure of an air conveyor according to an embodiment of the present invention. This air conveyor (indicated by reference numeral 2 as a whole) includes an upper horizontal section 2A and a lower horizontal section 2C. Are connected by an inclined section 2B to transport the container 4 from above to below.

前記エアコンベヤ２は、上部がエアダクト６になっており、このエアダクト６の下面側に一対のレール８が設けられている。エアコンベヤ２によって搬送される容器４（ＰＥＴボトル等の軽量容器）は、その首部にフランジが形成されており、このフランジの下面側が前記レール８によって支持されて搬送される。前記エアダクト６内には、天面および両側壁にエア通路（図示せず）が設けられており、搬送方向へ向かってエアを噴射する複数のトップブロア１０Ａ、１０Ｂ、１０Ｃから吹き込まれたエアが、このエア通路に設けられた多数の吹き出し口から前記容器４のレール８よりも上方の部分に吹き付けられることにより、容器４がレール８上を滑って図１の矢印方向に搬送される。   The air conveyor 2 has an air duct 6 at the top, and a pair of rails 8 are provided on the lower surface side of the air duct 6. The container 4 (lightweight container such as a PET bottle) transported by the air conveyor 2 has a flange formed at the neck, and the lower surface side of the flange is supported by the rail 8 and transported. In the air duct 6, air passages (not shown) are provided on the top surface and both side walls, and air blown from a plurality of top blowers 10A, 10B, and 10C that injects air in the transport direction. The container 4 is slid on the rail 8 and conveyed in the direction of the arrow in FIG. 1 by being sprayed from a large number of outlets provided in the air passage to a portion above the rail 8 of the container 4.

前記エアダクト６の下部は、レール８によって吊り下げられた状態の容器４の胴部を両側から覆う下部側壁１２が設けられている。この下部側壁１２内には、搬送方向と逆方向へエアを噴射するサイドブロア１４Ａ、１４Ｂからエアが吹き込まれており、傾斜区間２Ｂを搬送されてくる容器４の胴部を下方から上方へ向けて押し上げて、前記レール８に対して容器４がほぼ直角になるように姿勢を制御している。   The lower part of the air duct 6 is provided with a lower side wall 12 that covers the body of the container 4 suspended from the rail 8 from both sides. Air is blown into the lower side wall 12 from the side blowers 14A and 14B that inject air in the direction opposite to the conveyance direction, and the body of the container 4 conveyed in the inclined section 2B is directed upward from below. The posture is controlled so that the container 4 is substantially perpendicular to the rail 8.

上方側の水平区間２Ａの下流端に、下流側へ送る容器４の量を調整する容器量調整手段としての一対の回転ベルト（以下、第１回転ベルト１６と呼ぶ）が設けられている。これら一対の回転ベルト１６は、搬送される容器４を両側から挟時するようになっており、回転することにより挟持している容器４を下流側に搬送して傾斜区間２Ｂに送り込み、停止すると容器４の搬送を一時中止する。   A pair of rotating belts (hereinafter referred to as the first rotating belt 16) as container amount adjusting means for adjusting the amount of the container 4 to be sent to the downstream side is provided at the downstream end of the upper horizontal section 2A. The pair of rotating belts 16 sandwich the container 4 to be transported from both sides. When the container 4 is rotated, the container 4 is transported downstream, sent to the inclined section 2B, and stopped. The conveyance of the container 4 is temporarily stopped.

また、下方側の水平区間２Ｃの上流端に、下流に送る容器４の量を調整する容器量調整手段としての一対の回転ベルト（以下、第２回転ベルト１８と呼ぶ）が設けられている。この第２回転ベルト１８も、搬送される容器４を両側から挟時し、回転することにより挟持している容器４を下流側に送り出し、停止すると容器４の搬送を一時中止する。   In addition, a pair of rotating belts (hereinafter referred to as second rotating belts 18) as container amount adjusting means for adjusting the amount of the container 4 to be sent downstream is provided at the upstream end of the lower horizontal section 2C. The second rotating belt 18 also holds the container 4 to be transported from both sides, rotates to feed the sandwiched container 4 to the downstream side, and temporarily stops the transport of the container 4 when stopped.

前記傾斜区間２Ｂのほぼ中間部付近に第１の容器検出手段２０（第１センサー）が設けられ、この第１センサー２０よりもやや上流側に第２の容器検出手段２２（第２センサー）が設けられている。これら第１および第２センサー２０、２２の信号が、図示しない制御装置に入力され、この信号に応じて制御装置が前記第１回転ベルト１６および第２回転ベルト１８の作動を制御するようになっている。この実施例に係るエアコンベヤ２では、容器４の傷付きを防止するために、下方側の水平区間２Ｃから傾斜区間２Ｂの途中に至るまで容器４を前後に密着した状態にして搬送するようになっており、図１に示すように、前後に密着した状態の容器４の最後尾４Ａが、常に第１センサー２０と第２センサー２２の間に位置するように第１回転ベルト１６および第２回転ベルト１８の作動を制御する。   A first container detection means 20 (first sensor) is provided in the vicinity of an almost middle portion of the inclined section 2B, and a second container detection means 22 (second sensor) is provided slightly upstream from the first sensor 20. Is provided. The signals of the first and second sensors 20 and 22 are input to a control device (not shown), and the control device controls the operation of the first rotating belt 16 and the second rotating belt 18 in accordance with this signal. ing. In the air conveyor 2 according to this embodiment, in order to prevent the container 4 from being damaged, the container 4 is transported in a state where it is in close contact with the front and rear from the lower horizontal section 2C to the middle of the inclined section 2B. As shown in FIG. 1, the first rotating belt 16 and the second rotating belt 16 and the second rotating belt 16 are always positioned between the first sensor 20 and the second sensor 22 so that the rearmost 4A of the container 4 in close contact with the front and rear is located. The operation of the rotating belt 18 is controlled.

次に、前記構成のエアコンベヤ２の作動について説明する。運転の開始時には、下流側の第２回転ベルト１８の作動を停止した状態で、第１回転ベルト１６を回転させる。第１回転ベルト１６の回転により送り出された容器４は、傾斜区間２Ｂを搬送されて下方側の水平区間２Ｃに到達するが、第２回転ベルト１８が作動していないので、この第２回転ベルト１８の位置に停止する。以後送られてくる容器４は、前記第２回転ベルト１８によって停止している容器４の後方に、傾斜区間２Ｂの上流側に向けて次第に貯留されていく。このように運転が開始されて容器４が下方側の第２回転ベルト１８の位置に次第に貯留されていく当初は、容器４が第２センサー２２および第１センサー２０を素早く通過していくので、これらセンサー２２、２０はともにＯＦＦの状態である。   Next, the operation of the air conveyor 2 configured as described above will be described. At the start of operation, the first rotating belt 16 is rotated while the operation of the second rotating belt 18 on the downstream side is stopped. The container 4 delivered by the rotation of the first rotating belt 16 is transported through the inclined section 2B and reaches the lower horizontal section 2C. However, since the second rotating belt 18 is not operated, the second rotating belt Stop at position 18. The containers 4 sent thereafter are gradually stored behind the containers 4 stopped by the second rotating belt 18 toward the upstream side of the inclined section 2B. Since the container 4 gradually passes through the second sensor 22 and the first sensor 20 at the beginning when the operation is started in this way and the container 4 is gradually stored at the position of the second rotary belt 18 on the lower side, Both sensors 22 and 20 are in an OFF state.

下流側の第１センサー２０が所定時間ＯＮすると（つまり、下方側の第２回転ベルト１８から上方へ次第に貯留されてきた容器４の最後尾４Ａが、第１センサー２０の位置に到達すると）、この第１センサー２０からの信号を受けた制御装置は第２回転ベルト１８を回転させて、容器４を第２回転ベルト１８の下流側に送り出す。   When the first sensor 20 on the downstream side is turned ON for a predetermined time (that is, when the rearmost 4A of the container 4 that has been gradually stored upward from the second rotary belt 18 on the lower side reaches the position of the first sensor 20). Upon receiving the signal from the first sensor 20, the control device rotates the second rotating belt 18 and sends the container 4 to the downstream side of the second rotating belt 18.

第２回転ベルト１８から送り出される容器４の量と、上方側の第１回転ベルト１６から送り込まれて貯留されていく容器４の量とがバランスしているときには、貯留された容器４の最後尾４Ａが第１センサー２０と第２センサー２２との間に位置しており、第１回転ベルト１６と第２回転ベルト１８の両方を回転させて連続的に容器４を搬送することができる。   When the amount of the container 4 sent out from the second rotating belt 18 and the amount of the container 4 sent from the first rotating belt 16 on the upper side and stored are balanced, the last of the stored containers 4 4A is located between the first sensor 20 and the second sensor 22, and the container 4 can be continuously conveyed by rotating both the first rotating belt 16 and the second rotating belt 18.

第２回転ベルト１８から排出される容器４の量よりも第１回転ベルト１６から傾斜区間４Ｂに供給される容器４の量が多い場合には、次第に容器４の貯留量が増加し、最後尾の容器４Ａが第２センサー２２の位置にまで到達する。第２センサー２２まで容器４が貯留されて、第２センサー２２が所定時間ＯＮになると、制御装置が第１回転ベルト１６を停止させて上流側からの容器４の供給を一時停止する。その後、第２センサー２２がＯＦＦになると再び第１回転ベルト１６を回転して容器４の供給を再開する。   When the amount of the container 4 supplied from the first rotating belt 16 to the inclined section 4B is larger than the amount of the container 4 discharged from the second rotating belt 18, the storage amount of the container 4 gradually increases, The container 4 </ b> A reaches the position of the second sensor 22. When the container 4 is stored up to the second sensor 22 and the second sensor 22 is turned on for a predetermined time, the control device stops the first rotating belt 16 and temporarily stops the supply of the container 4 from the upstream side. Thereafter, when the second sensor 22 is turned off, the first rotating belt 16 is rotated again to restart the supply of the container 4.

逆に、第２回転ベルト１８から排出される容器４の量が、第１回転ベルト１６から供給される容器４の量よりも多い場合は、貯留されている容器４の量が次第に減少する。貯留された容器４の最後尾４Ａが次第に下降して第１センサー２０がＯＦＦになると、第２回転ベルト１８を停止して容器４の排出を中断する。このように、第１センサー２０および第２センサー２２からの信号により、第１回転ベルト１６および第２回転ベルト１８の回転、停止を制御して、常に、貯留されている容器４の最後尾４Ａが第１センサー２０と第２センサー２２の中間に位置するようにしており、傾斜区間２Ｂの下流側に貯留されている容器４は前後に密着した状態で搬送されているので、前後に振れて肩部等に傷が付くことがない。また、上方から傾斜区間２Ｂに貯留されている容器４に向かって搬送されてくる容器４は、傾斜区間２Ｂを単独で落下してくることになるが、傾斜区間２Ｂの搬送距離が短いので、容器４が傷付くおそれが減少する。   On the contrary, when the amount of the container 4 discharged from the second rotating belt 18 is larger than the amount of the container 4 supplied from the first rotating belt 16, the amount of the stored container 4 gradually decreases. When the rearmost 4A of the stored container 4 is gradually lowered and the first sensor 20 is turned off, the second rotating belt 18 is stopped and the discharge of the container 4 is interrupted. In this way, the rotation and stop of the first rotating belt 16 and the second rotating belt 18 are controlled by the signals from the first sensor 20 and the second sensor 22, and the rear end 4A of the container 4 stored at all times is controlled. Is positioned between the first sensor 20 and the second sensor 22, and the container 4 stored on the downstream side of the inclined section 2B is conveyed in close contact with the front and rear. There is no damage to the shoulders. In addition, the container 4 that is transported from above toward the container 4 stored in the inclined section 2B falls alone on the inclined section 2B, but the transport distance of the inclined section 2B is short, The risk of the container 4 being damaged is reduced.

図２は第２の実施例に係るエアコンベヤ１０２の側面図であり、このエアコンベヤ１０２も、上方側の水平区間１０２Ａと下方側の水平区間１０２Ｃとの間を傾斜区間１０２Ｂによって接続して、上方から下方へ容器４を搬送するようになっている。   FIG. 2 is a side view of the air conveyor 102 according to the second embodiment. This air conveyor 102 is also connected between the upper horizontal section 102A and the lower horizontal section 102C by an inclined section 102B. The container 4 is transported from above to below.

そして、前記第１実施例では、上方側の水平区間２Ａと下方側の水平区間２Ｃにそれぞれ下流に送る容器４の量を調整する容器量調整手段としての一対の回転ベルト１６、１８が設けられていたが、この実施例では、下方側の水平区間２Ｃにだけ一対の回転ベルト１１８からなる容器量調整手段が設けられている。   In the first embodiment, a pair of rotating belts 16 and 18 are provided as container amount adjusting means for adjusting the amount of the container 4 to be sent downstream to the upper horizontal section 2A and the lower horizontal section 2C. However, in this embodiment, the container amount adjusting means including the pair of rotating belts 118 is provided only in the lower horizontal section 2C.

また、第１実施例では、傾斜区間２Ｂ内に第１および第２の容器検出手段（センサー２０、２２）が配置されていたが、この実施例では、上方側の水平区間１０２Ａに第１容器量検出手段１２０（第１センサー）が設けられている。また、その下流側の傾斜区間１０２Ｂに、１個または複数個のセンサーが設けられている。この実施例では、傾斜区間１０２Ｂの上流部から下流端にかけて、ほぼ等間隔で４個の容器検出手段（第２センサー１２２、第３センサー１２４、第４センサー１２６および第５センサー１２８）が設けられている。なお、エアダクトおよびブロア等の構成は前記第１実施例と同一なので同一の符号を付してその説明を省略する。   In the first embodiment, the first and second container detection means (sensors 20, 22) are arranged in the inclined section 2B. In this embodiment, the first container is disposed in the upper horizontal section 102A. A quantity detecting means 120 (first sensor) is provided. One or a plurality of sensors are provided in the inclined section 102B on the downstream side. In this embodiment, four container detection means (second sensor 122, third sensor 124, fourth sensor 126, and fifth sensor 128) are provided at approximately equal intervals from the upstream portion to the downstream end of the inclined section 102B. ing. Since the construction of the air duct, blower, etc. is the same as that of the first embodiment, the same reference numerals are given and the description thereof is omitted.

この実施例では、運転の開始時には、下方側の水平区間１０２Ｃに設けられている回転ベルト１１８を停止させた状態で容器４の供給を開始する。上方側の水平区間１０２Ａから送られた容器４は、それぞれ傾斜区間１０２Ｂを搬送されて、下方側の水平区間１０２Ｃに到達し、作動していない回転ベルト１１８の位置で停止する。当初は、各センサー１２０、１２２、１２４、１２６、１２８の位置を容器４が単独で通過していくので、いずれのセンサー１２０、１２２、１２４、１２６、１２８も容器４を検出しないＯＦＦ状態である。   In this embodiment, at the start of operation, the supply of the container 4 is started with the rotating belt 118 provided in the lower horizontal section 102C being stopped. The containers 4 sent from the upper horizontal section 102A are respectively conveyed through the inclined section 102B, reach the lower horizontal section 102C, and stop at the position of the rotating belt 118 that is not operating. Initially, since the container 4 passes through the position of each sensor 120, 122, 124, 126, 128 alone, none of the sensors 120, 122, 124, 126, 128 is in the OFF state in which the container 4 is not detected. .

傾斜区間１０２Ｂを通って送られてきた容器４が回転ベルト１１８の後方に次第に貯留され、最後尾の容器４が最も下流側の第５センサー１２８の位置にまで到達すると、第５センサー１２８が所定時間以上容器４を検出してＯＮする。この時点では、第１センサー１２０から第４センサー１２６まではＯＦＦのままである。   When the container 4 sent through the inclined section 102B is gradually stored behind the rotating belt 118 and the last container 4 reaches the position of the fifth sensor 128 on the most downstream side, the fifth sensor 128 is set to a predetermined value. The container 4 is detected for more than the time and turned on. At this time, the first sensor 120 to the fourth sensor 126 remain OFF.

次々と上流側から容器４が供給されて貯留されてくると、前記第５センサー１２８に続いて第４センサー１２６がＯＮになり、その後、第３センサー１２４、第２センサー１２２がＯＮになり、最後に、第１センサー１２０がＯＮする。第１センサー１２０がＯＮになると、制御装置が回転ベルト１１８の運転を開始して、回転ベルト１１８の後方に貯留されている容器４を下流側に送り出す。このように第５センサー１２８から第１センサー１２０までのすべてのセンサーがＯＮの状態になると、搬送される容器４は、回転ベルト１１８の位置から第１センサー１２０の位置まで連続して密着した状態になっており、その後方から送られる容器４は、前方の容器４と密着した状態で、傾斜区間１０２Ｂを搬送されるので、容器４が前後に振られることがなく、傾斜区間１０２Ｂの搬送中に容器４に傷が付くことがない。   When the container 4 is supplied and stored one after another from the upstream side, the fourth sensor 126 is turned on following the fifth sensor 128, and then the third sensor 124 and the second sensor 122 are turned on, Finally, the first sensor 120 is turned on. When the first sensor 120 is turned on, the control device starts the operation of the rotating belt 118 and sends out the container 4 stored behind the rotating belt 118 to the downstream side. Thus, when all the sensors from the fifth sensor 128 to the first sensor 120 are in the ON state, the container 4 to be conveyed is in a state of being in close contact with the position of the first sensor 120 from the position of the rotating belt 118. Since the container 4 sent from the rear is conveyed in the inclined section 102B in close contact with the front container 4, the container 4 is not shaken back and forth, and is being conveyed in the inclined section 102B. The container 4 is not damaged.

前記のように回転ベルト１１８を作動させて容器４を下流側に送り出している状態の時に、第１センサー１２０がＯＦＦになったときは、回転ベルト１１８の回転を止めて容器４の下流側への送り出しを一時停止する。回転ベルト１１８を停止すると、再び上流側から搬送されてきた容器４が貯留されて第１センサー１２０がＯＮになるので、回転ベルト１１８の作動を再開して送り出しを始める。このようにして常に第１センサー１２０の位置まで連続して存在するように制御することにより、容器４の傷付きを防止できる。なお、第２センサー１２２〜第５センサー１２８は、途中容器４が隙間無く滞留していることを検出するために設けられている。   When the first sensor 120 is turned off when the rotating belt 118 is operated and the container 4 is sent to the downstream side as described above, the rotation of the rotating belt 118 is stopped and the container 4 is moved to the downstream side. Pauses sending out. When the rotating belt 118 is stopped, the container 4 transported from the upstream side is stored again, and the first sensor 120 is turned on. Therefore, the operation of the rotating belt 118 is resumed and feeding is started. Thus, by controlling so that it always exists to the position of the 1st sensor 120, damage to the container 4 can be prevented. The second sensor 122 to the fifth sensor 128 are provided to detect that the container 4 is staying on the way without a gap.

この第２実施例では、第１実施例と同様に傾斜区間１０２Ｂの搬送時に容器４の傷付きを防止でき、しかも、第１実施例と比較して回転ベルト１１８が一組でよく構造が簡単である。なお、第１センサー１２０を設ける位置は、必ずしも上方側の水平区間１０２Ａに限るものではなく、傾斜区間１０２Ｂの上流部であっても良い。但し、できるだけ上流端寄りの方が好ましい。また、第１センサー１２０以外のセンサー１２２、１２４、１２６、１２８の数および各センサーの間隔は、図示の構成に限るものではなく、適宜設定することができる。前記第１実施例では、傾斜区間２Ｂのほぼ中間まで容器４を貯留して搬送するようにしているので、大量の容器４を貯留すると押圧によって変形してしまうおそれのある容器４にも適用可能であるが、この第２実施例では、傾斜区間１０２Ｂのほぼ全域に容器４を貯留した状態で搬送するので、押圧がある程度かかっても変形しない容器４に適している。なお、前記各実施例では、容器量調整手段を一対の回転ベルト１６、１８、１１８から構成したが、この構成に限定されるものではなく、例えば、ロータリーホイール等のように容器４に係合して停止させることが可能なものであればよい。   In the second embodiment, as in the first embodiment, the container 4 can be prevented from being damaged during the conveyance of the inclined section 102B, and the rotating belt 118 is only one set and the structure is simple as compared with the first embodiment. It is. The position where the first sensor 120 is provided is not necessarily limited to the upper horizontal section 102A, but may be an upstream portion of the inclined section 102B. However, it is preferable to be as close to the upstream end as possible. Further, the number of sensors 122, 124, 126, 128 other than the first sensor 120 and the interval between the sensors are not limited to the illustrated configuration, and can be set as appropriate. In the first embodiment, since the container 4 is stored and transported to almost the middle of the inclined section 2B, it can be applied to the container 4 that may be deformed by pressing when a large amount of the container 4 is stored. However, in the second embodiment, since the container 4 is transported in a state where it is stored almost in the entire area of the inclined section 102B, the container 4 is suitable for the container 4 that does not deform even if it is pressed to some extent. In each of the above embodiments, the container amount adjusting means is constituted by the pair of rotating belts 16, 18, 118. However, the present invention is not limited to this structure. For example, the container amount adjusting means is engaged with the container 4 such as a rotary wheel. Anything that can be stopped is acceptable.
