To control the operation of use the motor 13 and the belt drive motor 19.

この商品取出し搬送装置では、制御装置30は、商品払出口52よりバケット6上、換言すれば、ベルトコンベア15の無端平ベルト18上に商品を受け取るたびに、ベルトコンベア15を、商品がベルトコンベア15の他方のストロークエンド側(右端側)へ移動する逆送り方向に駆動し、逆送り駆動開始後、規定時間内に商品到達スイッチ23が商品到達を検知すれば、バケット6の上昇移動を許可する。これに対し、規定時間内に商品到達スイッチ23が商品到達を検知しない場合には、ベルトコンベア15を、商品がベルトコンベア15の一方のストロークエンド側(左端側)へ移動する正送り方向に所定時間駆動した後、再びベルトコンベア15を逆送り方向に駆動して商品到達検知スイッチ23によって商品到達を監視し、所定回数に亙るベルトコンベア15の正送り駆動と逆送り駆動に拘わらず、商品到達スイッチ23が商品到達を検知しない場合には、商品取出し搬送動作を中断停止する制御を行う。   In this commodity take-out / conveyance device, the control device 30 causes the belt conveyor 15 to pass through the belt conveyor 15 every time the commodity is received on the bucket 6 from the commodity discharge outlet 52, in other words, on the endless flat belt 18 of the belt conveyor 15. 15 is driven in the reverse feed direction moving to the other stroke end side (right end side), and if the product arrival switch 23 detects the product arrival within a specified time after the start of reverse feed drive, the bucket 6 is allowed to move up. To do. On the other hand, when the product arrival switch 23 does not detect the arrival of the product within the specified time, the belt conveyor 15 is predetermined in the forward feed direction in which the product moves to one stroke end side (left end side) of the belt conveyor 15. After the time drive, the belt conveyor 15 is driven again in the reverse feed direction, and the arrival of the product is monitored by the product arrival detection switch 23, and the product arrival is reached regardless of whether the belt conveyor 15 is driven forward or backward for a predetermined number of times. When the switch 23 does not detect the arrival of the product, control for interrupting and stopping the product take-out and transport operation is performed.

つぎに、図3〜図8に示されている動作工程図と図9に示されているフローチャートを参照して上述の構成による商品取出し搬送装置の動作について説明する。   Next, the operation of the product take-out and conveyance device having the above-described configuration will be described with reference to the operation process diagrams shown in FIGS. 3 to 8 and the flowchart shown in FIG.

図3は待機状態を示しており、この状態下にて、購入者により自動販売機に対する通貨投入が行われ(ステップS10)、自動販売機前面の図示されていない商品選択スイッチがオンされると(ステップS11)、商品収納ラックより選択された商品Aの取り出しが行われ(ステップS12)、図4に示されているように、商品Aが商品払出口52より内扉フラッパ53を押し開いてバケット6のベルトコンベア15の無端平ベルト18上に落下する。   FIG. 3 shows a standby state. In this state, the purchaser enters a currency into the vending machine (step S10), and a product selection switch (not shown) on the front of the vending machine is turned on. (Step S11), the product A selected from the product storage rack is taken out (Step S12), and the product A pushes and opens the inner door flapper 53 from the product delivery outlet 52, as shown in FIG. The bucket 6 falls on the endless flat belt 18 of the belt conveyor 15.

つぎに、図5に示されている商品Aがベルトコンベア15の他方のストロークエンド側(右端側)へ移動する逆送り方向にベルトコンベア15を駆動し(ステップS13)、商品到達スイッチ23がオンするかを監視する(ステップS14)。ベルトコンベア15の逆方向駆動により、無端平ベルト18上の商品Aは、商品受け台2とは逆の方向に横送りされる。ベルトコンベア15の逆送り駆動開始後、規定時間内に商品到達スイッチ23が商品到達を検知すれば(図6参照)、商品払出口52よりベルトコンベア15に対する商品受け取りが正常に行われたと判断し、バケット6の上昇移動を許可すべく、つぎのステップへ進む。   Next, the product A shown in FIG. 5 is driven in the reverse feed direction in which the product A moves to the other stroke end side (right end side) of the belt conveyor 15 (step S13), and the product arrival switch 23 is turned on. Whether to do so is monitored (step S14). By the reverse drive of the belt conveyor 15, the product A on the endless flat belt 18 is laterally fed in the direction opposite to the product receiving tray 2. If the product arrival switch 23 detects the arrival of the product within a specified time after starting the reverse feed driving of the belt conveyor 15 (see FIG. 6), it is determined that the product has been normally received from the product delivery outlet 52 to the belt conveyor 15. In order to permit the upward movement of the bucket 6, the process proceeds to the next step.

これに対し、規定時間内に商品到達スイッチ23が商品到達を検知しない場合には、ベルトコンベア15を、商品がベルトコンベア15の一方のストロークエンド側(左端側)へ移動する正送り方向に所定時間に亙って駆動し(ステップS15)、その後、再び、ベルトコンベア15を逆送り方向に駆動し(ステップS13)、再度、商品到達検知スイッチ23がオンするかを監視する(ステップS14)。   On the other hand, when the product arrival switch 23 does not detect the arrival of the product within the specified time, the belt conveyor 15 is predetermined in the forward feed direction in which the product moves to one stroke end side (left end side) of the belt conveyor 15. It is driven over time (step S15), and then the belt conveyor 15 is again driven in the reverse feed direction (step S13), and it is monitored again whether the commodity arrival detection switch 23 is turned on (step S14).

上述のようなリトライ動作により、商品払出口52よりベルトコンベア15に対する商品受け取りの異常性の解消することが試みられる。このリトライ動作において、無端平ベルト18の回転位相に応じて桟21が、商品Aを押すように作用し、商品Aが商品払出口52の部分に引っかかっていることを積極的に解消するように作用する。   By the retry operation as described above, it is attempted to eliminate the abnormality in the receipt of the product for the belt conveyor 15 from the product discharge outlet 52. In this retry operation, the crosspiece 21 acts to push the product A in accordance with the rotational phase of the endless flat belt 18 so as to positively eliminate the product A being caught on the product payout 52 portion. Works.

上述のようなリトライ動作は、所定回数、たとえば3回まで行われ、所定回数に亙るベルトコンベア15のリトライ動作に拘わらず、商品到達スイッチ23が商品到達を検知しない場合には、すなわち、商品Aが商品払出口52の部分に引っかかっていることが解消されない場合には、商品取出し搬送動作を中断停止する(ステップS34)。   The retry operation as described above is performed a predetermined number of times, for example, up to three times. When the product arrival switch 23 does not detect the arrival of the product regardless of the retry operation of the belt conveyor 15 over the predetermined number of times, that is, the product A If it is not resolved that the product is caught in the product payout port 52, the product take-out and transport operation is suspended and stopped (step S34).

商品到達スイッチ23がオンすると、つぎに、各商品払出口52毎に設けられている内扉フラッパスイッチ31が全てオンしたか否かを判別する(ステップS16)。内扉フラッパスイッチ31が全てオン、換言すれば、各商品払出口52の内扉フラッパ53が閉じていることが確認されると、商品Aが商品払出口52の部分に引っかかることなく、商品払出口52よりベルトコンベア15に対する商品受け取りが正常に行われたと判断し、つぎのステップへ進む。   When the commodity arrival switch 23 is turned on, it is next determined whether or not all the inner door flapper switches 31 provided for the respective commodity outlets 52 have been turned on (step S16). When all the inner door flapper switches 31 are turned on, in other words, when it is confirmed that the inner door flapper 53 of each commodity outlet 52 is closed, the commodity A is not caught on the part of the commodity outlet 52, and the commodity payment It is determined that the product has been normally received from the exit 52 to the belt conveyor 15, and the process proceeds to the next step.

これに対し、内扉フラッパスイッチ31が全てオンしない場合も、ベルトコンベア15を、商品がベルトコンベア15の一方のストロークエンド側(左端側)へ移動する正送り方向に所定時間に亙って駆動し(ステップS17)、その後、再び、ベルトコンベア15を逆送り方向に駆動し(ステップS18)、再度、内扉フラッパスイッチ31が全てオンするかを監視する(ステップS16)。   On the other hand, even when all the inner door flapper switches 31 are not turned on, the belt conveyor 15 is driven for a predetermined time in the forward feed direction in which the product moves to one stroke end side (left end side) of the belt conveyor 15. Then (step S17), the belt conveyor 15 is again driven in the reverse feed direction (step S18), and it is again monitored whether all the inner door flapper switches 31 are turned on (step S16).

上述のようなリトライ動作により、商品払出口52よりベルトコンベア15に対する商品受け取りの異常性の解消することが試みられる。このリトライ動作においても、無端平ベルト18の回転位相に応じて桟21が、商品Aを押すように作用し、商品Aが商品払出口52の部分に引っかかっていることを積極的に解消するように作用する。   By the retry operation as described above, it is attempted to eliminate the abnormality in the receipt of the product for the belt conveyor 15 from the product discharge outlet 52. Also in this retry operation, the crosspiece 21 acts to push the product A according to the rotational phase of the endless flat belt 18 so as to positively eliminate the product A being caught on the product payout port 52. Act on.

上述のようなリトライ動作は、所定回数、たとえば3回まで行われ、所定回数に亙るベルトコンベア15のリトライ動作に拘わらず、内扉フラッパスイッチ31が全てオンしない場合には、すなわち、商品Aが商品払出口52の部分に引っかかっていることが解消されない場合には、商品取出し搬送動作を中断停止する(ステップS34)。   The retry operation as described above is performed a predetermined number of times, for example, up to three times. When the inner door flapper switch 31 is not all turned on regardless of the retry operation of the belt conveyor 15 over the predetermined number of times, that is, the product A is If it is not resolved that the product has been caught in the product outlet 52, the product take-out and transportation operation is suspended and stopped (step S34).

内扉フラッパスイッチ31が全てオンし、商品払出口52よりベルトコンベア15に対する商品受け取りが正常に行われたと判断すると、ベルトコンベア15を停止し(ステップS19)、バケット6を上昇駆動し(ステップS20)、上昇スイッチ34がオンすることを監視する(ステップS21)。   If all the inner door flapper switches 31 are turned on and it is determined that the goods have been normally received from the product delivery port 52 to the belt conveyor 15, the belt conveyor 15 is stopped (step S19), and the bucket 6 is driven up (step S20). ) And monitors that the ascent switch 34 is turned on (step S21).

バケット6の上昇駆動開始から所定時間が経過しても、上昇スイッチ34がオンしない場合には、一旦、バケット6を所定時間だけ降下駆動し(ステップS22,ステップS23)、ベルトコンベア15を所定時間だけ逆方向駆動し(ステップS24)、再度、バケット6を上昇駆動する(ステップS19)。このようなリトライ動作は、所定回数、たとえば3回まで行われ、所定回数に亙るリトライ動作に拘わらず、上昇スイッチ34がオンしない場合には、搬送ミス発生と判断して商品取出し搬送動作を中断停止する(ステップS34)。   If the ascending switch 34 is not turned on even after a predetermined time has elapsed from the start of the ascending drive of the bucket 6, the bucket 6 is once lowered and driven for a predetermined time (steps S22 and S23), and the belt conveyor 15 is moved for a predetermined time. Only in the reverse direction (step S24), the bucket 6 is again driven up (step S19). Such a retry operation is performed a predetermined number of times, for example, up to three times. If the ascending switch 34 is not turned on regardless of the predetermined number of retry operations, it is determined that a transport error has occurred and the product take-out transport operation is interrupted. Stop (step S34).

上昇スイッチ34がオンすれば、すなわち、バケット6が正常に所定の上昇位置に到着すれば、バケット6の上昇駆動を停止し(ステップS25)、ベルトコンベア15を正送り方向に駆動する(ステップS26)。これにより、図7に示されているように、無端平ベルト18上の商品Aが商品受け台2側へ搬送される。商品Aは、この搬送移動に伴って払出板24に当たり、払出板24によって商品受け台2へ払い出される(図8参照)。この際、商品Aは、商品受取口3の商品搬出フラッパ5を押し開いて商品受け台2へ払い出され、商品搬出スイッチ32がオンからオフに移行すること、換言すれば、商品搬出フラッパ5が商品Aによって押し開かれ、商品Aが商品受け台2に払い出されることにより、商品搬出フラッパ5が正常に閉じたことを確認する(ステップS27)。   If the ascent switch 34 is turned on, that is, if the bucket 6 normally reaches the predetermined ascending position, the ascending drive of the bucket 6 is stopped (step S25), and the belt conveyor 15 is driven in the forward feed direction (step S26). ). Thereby, as shown in FIG. 7, the product A on the endless flat belt 18 is conveyed to the product receiving tray 2 side. The product A hits the payout plate 24 along with the transport movement, and is sent out to the product receiving tray 2 by the payout plate 24 (see FIG. 8). At this time, the merchandise A is pushed out of the merchandise carry-out flapper 5 of the merchandise receiving opening 3 and delivered to the merchandise receiving tray 2, and the merchandise carry-out switch 32 shifts from on to off, in other words, the merchandise carry-out flapper 5. Is pushed open by the product A, and the product A is paid out to the product cradle 2 to confirm that the product carry-out flapper 5 is normally closed (step S27).

ベルトコンベア15の正方向駆動開始後、所定時間が経過しても、商品搬出スイッチ32がオンからオフに移行しない場合には、ベルトコンベア15を所定時間に亙って逆方向駆動し(ステップS28)、その後、再び、ベルトコンベア15を正方向駆動し(ステップS26)、再度、商品搬出スイッチ32がオンからオフに移行するかを監視する(ステップS27)。このようなリトライ動作は、所定回数、たとえば3回まで行われ、所定回数に亙るリトライ動作に拘わらず、商品搬出スイッチ32がオンからオフに移行しない場合には、商品搬出ミス発生と判断して商品取出し搬送動作を中断停止する(ステップS34)。   If the product carry-out switch 32 does not shift from on to off even after a predetermined time has elapsed after the belt conveyor 15 starts to drive in the forward direction, the belt conveyor 15 is driven in the reverse direction over the predetermined time (step S28). Thereafter, the belt conveyor 15 is again driven in the forward direction (step S26), and it is monitored again whether the commodity carry-out switch 32 shifts from on to off (step S27). Such a retry operation is performed a predetermined number of times, for example, up to three times. If the product carry-out switch 32 does not shift from ON to OFF regardless of the predetermined number of retry operations, it is determined that a product carry-out error has occurred. The product takeout / conveying operation is interrupted and stopped (step S34).

なお、このリトライ動作において、無端平ベルト18の回転位相によっては、桟21が、商品Aを押すように作用し、商品Aの搬出が正常に行われるように作用する。   In this retry operation, depending on the rotational phase of the endless flat belt 18, the crosspiece 21 acts to push the product A and the product A is normally carried out.

商品搬出スイッチ32がオンからオフに移行すれば、ベルトコンベア15を停止し(ステップS29)、バケット6を降下駆動し(ステップS30)、降下スイッチ33がオンすることを監視する(ステップS31)。   If the product carry-out switch 32 shifts from on to off, the belt conveyor 15 is stopped (step S29), the bucket 6 is driven to descend (step S30), and it is monitored that the descent switch 33 is turned on (step S31).

バケット6の降下駆動開始から所定時間が経過しても、降下スイッチ33がオンしない場合には、一旦、バケット6を所定時間だけ上昇駆動し(ステップS32,ステップS33)、再度、バケット6を降下駆動する(ステップS30)。このようなリトライ動作は、所定回数、たとえば3回まで行われ、所定回数に亙るリトライ動作に拘わらず、降下スイッチ33がオンしない場合には、戻し動作ミス発生と判断して商品取出し搬送動作を中断停止する(ステップS34)。   If the descent switch 33 does not turn on even after a predetermined time has elapsed since the descent driving of the bucket 6 starts, the bucket 6 is once driven up for a predetermined time (steps S32 and S33), and the bucket 6 is lowered again. Drive (step S30). Such a retry operation is performed a predetermined number of times, for example, up to three times. If the lowering switch 33 is not turned on regardless of the predetermined number of retry operations, it is determined that a return operation error has occurred and the product take-out and transport operation is performed. The interruption is stopped (step S34).

降下スイッチ33がオンし、バケット6が所定の降下位置に降下すれば、バケット6の降下駆動停止する(ステップS35)。これにより、バケット6は元の待機位置に戻る。   When the lowering switch 33 is turned on and the bucket 6 is lowered to a predetermined lowering position, the lowering drive of the bucket 6 is stopped (step S35). Thereby, the bucket 6 returns to the original standby position.

商品Aは商品受け台2に載せられた状態で、商品取出口4より取り出されるから、商品Aが押さえられても、バケット6が押し下げられることはなく、商品Aの取り出しが行えなくなるような事態になることがない。   Since the product A is taken out from the product outlet 4 while being placed on the product cradle 2, even if the product A is pressed, the bucket 6 is not pushed down and the product A cannot be taken out. Never become.
