特開2007−246267号公報JP 2007-246267 A 実用新案登録第3074587号公報Utility model registration 3074587 gazette

特許文献1に示される食器整理装置(食器積重ね装置)は、待機位置に停止した食器を持ち上げ搬送する持ち上げ搬送手段と、この持ち上げ搬送手段から食器を受け取り、複数の食器を積み重ね状態に支持する支持部と、を備える。持ち上げ搬送手段は回動中心軸線(X)を中心として第1駆動手段および第2駆動手段により往復回動し、順次待機位置を通過して食器を持ち上げ搬送して、食器は支持部と第1爪部に支持されて積重ねられていく。
支持部に設定数の食器が積重ねられると、持ち上げ搬送手段は回動中心軸線(X)を中心として第3駆動手段により上方に回動して設定数の積重ね状態の食器を押し上げ、支持部と第2爪部で支持するものである。
The table arrangement device (tableware stacking device) shown in Patent Document 1 includes a lifting and conveying means for lifting and conveying the dishes stopped at the standby position, and supports for receiving the dishes from the lifting and conveying means and supporting the plurality of dishes in a stacked state And a unit. The lifting and conveying means is reciprocally pivoted about the pivoting center axis (X) by the first drive means and the second drive means, and sequentially passes through the standby position to lift and convey the tableware, and the tableware is the support portion and the first It is supported by the claws and piled up.
When the set number of dishes is stacked on the support portion, the lifting and conveying means is pivoted upward by the third drive means about the pivot center axis (X) to push up the set number of stacked dishes, and the support portion and It supports by the 2nd nail part.

特許文献2に示される食器整理装置は、前進および後退する食器押出板を有するスタッカーを備え、スタッカーの前進後退を繰り返すことにより、待機位置に移送された起立姿勢の食器を所定枚数になるまで重ね合わせて(積み重ねて)第1整理爪に保持させ、その後、スタッカーの前進動作により所定枚数の重ね合わされた食器を押出して第2整理爪に保持させるものである。   The tablekeeping device shown in Patent Document 2 includes a stacker having a table pushing plate moving forward and backward, and by repeatedly advancing and retracting the stacker, the tableware in the standing posture transferred to the standby position is overlapped until a predetermined number of sheets are reached. In combination (stacked), the first organizing claw is held, and thereafter, a predetermined number of stacked dishes are pushed out and held by the second organizing claw by the advancing operation of the stacker.

しかしながら、特許文献1に示される食器整理装置においては、持ち上げ搬送手段が、回動中心軸線(X)を中心として第1駆動手段により上方に回動して設定数に達した積重ね状態の食器を押し上げ、支持部と第2爪部で支持させる動作中においては、待機位置に停止した食器を持ち上げ搬送して支持部に順次積み重ねる動作を同時並行的に行うことができない。すなわち積重ね状態の食器を押し上げ、支持部と第2爪部で支持させる動作に要する時間は、支持部に順次積み重ねる動作を実行できずロスタイムとなる。   However, in the dish arrangement shown in Patent Document 1, the lifting and conveying means is rotated upward by the first driving means about the rotational center axis (X) to reach the set number of dishes in the stacked state. During the operation of pushing up and supporting by the support portion and the second claw portion, the operation of lifting and conveying the tableware stopped at the standby position and sequentially stacking on the support portion can not be performed simultaneously in parallel. That is, the time required for the operation of pushing up the stacked dishes and supporting them by the support portion and the second claw portion can not perform the operation of sequentially stacking on the support portion, resulting in a loss time.

つまり、食器洗浄装置側において、例えば設定数に達した積重ね状態の食器を押し上げる動作中において洗浄装置のコンベアを一時停止等の制御を行い、食器整理装置側に搬送される後続の食器を一時的に制限すること、又は食器洗浄装置のコンベアに載置して搬送する際、設定数ごとの食器間に間隔を空け、この食器の無い間隔に相当する搬送時間内に、積み重ね状態の食器を押し上げる動作を行うことが必要となる。   That is, for example, during the operation of pushing up the stacked dishes reaching the set number on the dishwashing machine side, control is performed such as temporarily stopping the conveyor of the washing machine, and the subsequent dishes transported to the dishwashing machine side are temporarily used. When loading on the conveyor of the dishwashing device or carrying it, the set number of dishes are spaced, and the stacked dishes are pushed up within the transport time corresponding to the interval without the dishes. It is necessary to carry out the operation.

したがって、食器洗浄装置側においては食器整理装置とのマッチングをとるための制御、煩雑な作業が必要であり、かつ単位時間当たりの食器の洗浄処理数が下がり洗浄効率が低下する課題がある。
また、食器整理装置としても単位時間当たりに積み重ねる食器の処理数が少なくなり、整理動作の効率が低下する課題がある。
Therefore, on the dishwashing device side, control for achieving matching with the dishwashing device and complicated work are required, and there is a problem that the number of washing processing of the dishes per unit time decreases and the washing efficiency decreases.
Moreover, the number of dishes processed per unit time decreases as the tableware arranging device, and there is a problem that the efficiency of the arranging operation is reduced.

また、特許文献2に示される食器整理装置においては、スタッカーが、待機位置に移送された起立姿勢の食器を所定枚数になるまで重ね合わせて第1整理爪に保持させる機能と、所定枚数の重ね合わされた食器を押出して第2整理爪に保持させる機能との2つの機能を合わせ持つことになる。
この2つの機能を同時並行的ではなく、時系列的に実行せざるを得ず、前記特許文献1に記載の食器整理装置と同様な課題を有している。
Further, in the tableware organizing apparatus shown in Patent Document 2, the stacker has a function of superposing the tableware in the standing posture transferred to the standby position until the predetermined number of sheets is reached and holding the table by the first organizing claw; The combined function of extruding the cut-out tableware and holding it on the second organizing claw is to be combined.
These two functions are not performed in parallel but in a time series manner, and have the same problems as the tableware arranging device described in Patent Document 1.

押出爪941は、押出爪の駆動手段950により往復動されるスライダー944に設けられている。押出爪941と駆動手段950とは、押上げ機構940を構成している。スライダー944を駆動する駆動手段950については後述する。   The pushing claw 941 is provided on a slider 944 which is reciprocated by driving means 950 of the pushing claw. The push-out claw 941 and the drive means 950 constitute a push-up mechanism 940. The drive means 950 for driving the slider 944 will be described later.

押出爪941は、第1保持爪916および第2保持爪917と同等の三角形状とされ、所定枚数の食器Wごと取出し位置P3に押出すために、第1保持爪916と同等位置の待機位置と、第2保持爪917による食器Wの保持位置よりも移動方向下流側となる前進位置と、の間で往復動される。押出爪941は、押し板922の往復動と干渉を起こすことなく往復動可能に構成されている。   The push-out claw 941 has a triangular shape equivalent to the first holding claw 916 and the second holding claw 917, and is a standby position equivalent to the first holding claw 916 in order to push a predetermined number of dishes W to the taking-out position P3. And a forward position where the second holding claw 917 moves downstream of the holding position of the tableware W. The pushing claw 941 is configured to be capable of reciprocating without causing interference with the reciprocating movement of the pressing plate 922.

本実施形態では、押し板922は、その往復動時に押出爪941および第1保持爪916と干渉しない形状とされている。また、押出爪941は、取出し位置に食器Wを押出した後の復路において、押出し動作中に整理位置P2に受入れた搬送されてくる後続の食器Wがあって、その食器Wと干渉したとき、押出爪941の三角形状およびバネ機構により退避できるように構成されている。   In the present embodiment, the pressing plate 922 is shaped so as not to interfere with the pushing claws 941 and the first holding claws 916 when reciprocating. Also, when there is a subsequent tableware W received at the disposal position P2 during the extrusion operation and when it interferes with the tableware W, in the return path after pushing the tableware W out to the removal position, the extrusion claw 941 The push-out claw 941 is configured to be able to be retracted by the triangular shape and the spring mechanism.

なお、押し板922により食器Wを整理位置P2に押出すときに、食器Wが待機位置にある押出爪941に当るが、押出爪941は、その三角形状およびバネ機構により退避する。   When the tableware W is pushed to the sorting position P2 by the push plate 922, the tableware W hits the pushing claw 941 in the standby position, but the pushing claw 941 is retracted by the triangular shape and the spring mechanism.

押出爪941すなわち、押出爪942a,942b,942c,942dは、カバー913内にホルダー911の底面911aに平行に配置されるレール943に案内され移動可能なスライダー944のアーム945a,945bにバネ機構を介して取付けられている。この構成により、押出爪941は一体となってホルダー911の底面911aと平行にスライド移動自在となる。   The push-out claws 941, ie push-out claws 942 a, 942 b, 942 c, 942 d are guided by rails 943 disposed in the cover 913 parallel to the bottom surface 911 a of the holder 911. It is attached through. With this configuration, the push-out claws 941 can slide integrally in parallel with the bottom surface 911 a of the holder 911.

押出爪941を駆動する押出爪の駆動手段950について説明する。押出爪の駆動手段950は、駆動モータ951を駆動源とし、それにより回転駆動されるリンク板952、リンク板952と一体のセンサー用板953、およびリンク板952の先端に回転自在に連結されたリンクバー954から成るリンク機構を備える。   The pushing claw driving means 950 for driving the pushing claw 941 will be described. The driving means 950 of the push-out claw has a driving motor 951 as a driving source, and is rotatably connected to the link plate 952 driven thereby, the sensor plate 953 integral with the link plate 952, and the tip of the link plate 952 A link mechanism consisting of a link bar 954 is provided.

リンクバー954は、その先端にスライダー944が回転自在に連結され、スライダー944にアーム945a,945bを介して押出爪941、すなわち押出爪942a,942b,942c,942dが取付けられている。   The link bar 954 has a slider 944 rotatably connected to the tip thereof, and an extruding claw 941, that is, extruding claws 942 a, 942 b, 942 c, 942 d are attached to the slider 944 via arms 945 a, 945 b.

センサー用板953は、リンク板952の回転位置を、光学式又は接触式の位置検出センサー955により検出するためのものである。位置検出センサー955の検出信号は、押出爪941が待機位置に戻ったことの基準信号となり、その信号に基づいて駆動モータ951は動作する。駆動モータ951は、制御装置1000への食器センサー901および位置検出センサー955からの信号入力に基づいて間欠的に運転制御される。   The sensor plate 953 is for detecting the rotational position of the link plate 952 by an optical or contact position detection sensor 955. The detection signal of the position detection sensor 955 is a reference signal that the push-out claw 941 has returned to the standby position, and the drive motor 951 operates based on the signal. The drive motor 951 is intermittently controlled to operate based on the signal input from the tableware sensor 901 and the position detection sensor 955 to the control device 1000.

(食器整理装置の運転動作)
次に、本発明の一実施形態である食器整理装置900の運転動作について、図8〜図12を参照しながら説明する。
(Driving operation of tableware management)
Next, the driving operation of the tableware arranging apparatus 900 according to the embodiment of the present invention will be described with reference to FIGS.

(運転動作の概略)
本実施形態の制御装置1000による、浸漬装置200、分離反転装置600における昇降手段400、分離手段500および反転手段700、洗浄装置800の動作の詳細はここでは省き、食器整理装置900の動作について説明する。
(Outline of driving operation)
The details of the operation of the immersing apparatus 200, the lifting and lowering means 400 in the separating and inverting apparatus 600, the separating means 500 and the reversing means 700, and the cleaning apparatus 800 by the control apparatus 1000 of the present embodiment are omitted here. Do.

図8は、食器整理装置900の運転方法に係る手順を示す。食器整理装置900のホルダー911には、洗浄装置800により本洗浄された下向きの食器Wが1枚ずつ搬入される。スタッカー921の押し板922は、ホルダー911に受入れた食器Wを1枚ずつ整理位置P2へ押出す(S31)。押し板922は押し板の駆動手段930により所定周期で連続して往復動されており、整理位置P2への押出し動作は繰り返される。   FIG. 8 shows a procedure according to the method of operating the tableware management device 900. The downward dishes W which have been substantially cleaned by the cleaning device 800 are carried one by one into the holder 911 of the tableware arranging device 900. The push plate 922 of the stacker 921 pushes the dishes W received by the holder 911 one by one to the sorting position P2 (S31). The push plate 922 is continuously reciprocated in a predetermined cycle by the drive means 930 of the push plate, and the pushing operation to the organizing position P2 is repeated.

この所定周期は、食器Wが洗浄装置800から搬送されてくる周期と同じ、もしくは少し短くしておけば、効率良く食器Wを1枚ずつ整理のために押出すことができる。押し板922の往復動の所定周期は、例えば略1秒としており、食器Wが洗浄装置800から搬送されてくる周期は例えば略1.5秒としている。食器Wは、この周期分の間隔をおいて連続して次々と搬送されてくる。   If the predetermined period is set to be the same as or slightly shorter than the period in which the dishes W are transported from the cleaning device 800, the dishes W can be efficiently pushed out for sorting one by one. The predetermined cycle of the reciprocating motion of the push plate 922 is, for example, approximately 1 second, and the cycle of the tableware W being transported from the cleaning device 800 is, for example, approximately 1.5 seconds. The dishes W are conveyed one after another continuously at intervals of this cycle.

食器センサー901による食器のカウントが所定枚数になったとき(S32でYes)、押出爪941が押出爪の駆動手段950により1往復だけ往復動され、所定枚数積み重ねられた食器Wをホルダー911の取出し位置に押出す(S33)。押出爪941の往復動にかかる動作時間は、例えば略3秒としている。
次いで、取出し位置の所定枚数の食器Wは作業者により取り出される(S34)。
When the number of dishes counted by the tableware sensor 901 reaches a predetermined number (Yes in S32), the pushing claw 941 is reciprocated by the pushing claw driving means 950 for one reciprocation, and the predetermined number of stacked dishes are taken out of the holder 911 Extrude into position (S33). The operation time taken for the reciprocating movement of the pushing claw 941 is, for example, approximately 3 seconds.
Next, the predetermined number of dishes W at the removal position are removed by the worker (S34).

このようにして、次々と洗浄装置800から搬送されてくる食器Wの受入れ位置P1への受入れ、および押し板922による整理位置P2への食器Wを押出す整理動作は、食器Wが所定枚数になったときに間欠的に行われる押出爪941による食器の取出し位置P3へ押出す押上げ動作中にも連続的に行われる。   In this manner, the tableware W receives a predetermined number of sheets for receiving the tableware W successively transported from the cleaning device 800 to the receiving position P1 and pushing out the tableware W to the sorting position P2 by the push plate 922 It is also continuously performed during the pushing-up operation of pushing the dish to the taking-out position P3 by the pushing claw 941 which is intermittently performed when it becomes.

つまり、整理位置P2へと押出す整理動作と、取出し位置P3へと押出す押上げ動作とは並行して行われる。また、食器センサー901により検知された信号を、押出爪941による押上げ動作のタイミングの基準とするので、押出爪941による押上げ動作タイミングが的確なものとなる。   That is, the organizing operation of pushing to the colliding position P2 and the pushing operation of pushing to the take-out position P3 are performed in parallel. Further, since the signal detected by the tableware sensor 901 is used as a reference of the timing of the push-up operation by the push-out claw 941, the push-up operation timing by the push-out claw 941 becomes accurate.

(スタッカーの動作)
先ず、図9を参照しながら整理機構920の動作を説明する。駆動モータ931が駆動され、カム板932が回転すると、カムレバー933はカムレバーの基端935を支点に所定範囲で往復回動する。カムレバー933の往復回動動作は、ロッド934を介在することでレバー923の直線的な往復動に変換される。その結果、レバー923に連結された押し板922は、前記した退避位置と進出位置との間で往復動する。押し板922は、制御装置1000により連続して往復動するよう制御される。
(Operation of the stacker)
First, the operation of the organizing mechanism 920 will be described with reference to FIG. When the drive motor 931 is driven and the cam plate 932 rotates, the cam lever 933 reciprocates in a predetermined range around the base end 935 of the cam lever. The reciprocating rotational movement of the cam lever 933 is converted into linear reciprocating movement of the lever 923 by interposing the rod 934. As a result, the push plate 922 connected to the lever 923 reciprocates between the retracted position and the advanced position described above. The push plate 922 is controlled by the control device 1000 to continuously reciprocate.

ここに、カム作用点がカムレバー933の中間にあるカム機構でもって押し板922は駆動されるので、押し板922の退避位置から進出位置に移動するとき、移動直後の速度は遅く、漸次早くなり、再び遅くなる。このため、押し板922が食器Wを押出すために接触するときに、食器Wに衝撃を与えることが少なくなり、好適である。なお、押し板の駆動手段930は、上記カム機構を用いたものに限られず、往復動させる任意の構成を採用し得る。   Here, since the push plate 922 is driven by the cam mechanism whose cam action point is in the middle of the cam lever 933, when moving from the retracted position of the push plate 922 to the advanced position, the speed immediately after the movement is slower and gradually faster. , Will be late again. For this reason, when the push plate 922 comes in contact for extruding the dishes W, the dishes W are less likely to be shocked, which is preferable. In addition, the drive means 930 of a push plate is not restricted to what used the said cam mechanism, Arbitrary structures which reciprocate are employable.

(押出し爪の動作)
次に、図10を参照しながら押上げ機構940の動作を説明する。駆動モータ951が駆動され、リンク板952およびセンサー用板953が回転されると、リンクバー954のリンク板952側の一端は、リンク板952の軸廻りに回転され、それに伴いリンクバー954の他端側は、レール943に案内されるスライダー944に回転軸で連結されているので、レール943に沿った直線的な往復動に変換される。その結果、スライダー944は往復動し、スライダー944に取付けられている押出爪941は、待機位置と、第2保持爪917による食器Wの保持位置よりも移動方向下流側となる前進位置と、の間で往復動する。押出爪941は、制御装置1000により整理位置P2の食器Wが所定枚数となったときに、間欠的に、1往復だけ往復動するよう制御される。
(Operation of pushing claws)
Next, the operation of the push-up mechanism 940 will be described with reference to FIG. When the drive motor 951 is driven and the link plate 952 and the sensor plate 953 are rotated, one end of the link bar 954 on the link plate 952 side is rotated about the axis of the link plate 952 and accordingly the other link bar 954 The end side is connected to the slider 944 guided by the rail 943 at the rotation axis, so it is converted into linear reciprocation along the rail 943. As a result, the slider 944 reciprocates, and the pushing claw 941 attached to the slider 944 has a standby position, and an advancing position downstream of the holding position of the tableware W by the second holding claw 917 in the moving direction. Reciprocate between. The extruding claw 941 is controlled by the control device 1000 to intermittently reciprocate by only one reciprocation when the number of dishes in the sorting position P2 reaches a predetermined number.

ここに、前記したリンク機構の動作は、リンクバー954のリンク板952側の軸廻り回転面と、スライダー944の往復動方向とが平行な面内にあり、円運動に基づく往復動となる。   Here, the operation of the link mechanism described above is in a plane in which the axial rotation surface on the link plate 952 side of the link bar 954 and the reciprocation direction of the slider 944 are parallel, and becomes reciprocation based on circular motion.

このため、押出爪941が待機位置から押出し位置に移動するとき、移動直後の速度は遅く、漸次早くなり、再び遅くなる。このため、押出爪941が食器Wを押出しするために接触するときに、食器Wに衝撃を与えることが少なくなり、好適である。なお、押出爪の駆動手段950は、上記リンク機構を用いたものに限られず、往復動させる任意の構成を採用し得る。   For this reason, when the push-out claw 941 moves from the standby position to the push-out position, the speed immediately after the movement is slow, gradually becomes faster, and becomes slower again. For this reason, when the push-out claw 941 comes into contact for pushing out the dish W, impact on the dish W is reduced, which is preferable. The pushing claw driving means 950 is not limited to the one using the above-mentioned link mechanism, but may adopt any configuration for reciprocating.

(一連の運転動作)
次に、図11および図12を参照しながら、洗浄装置800から搬送されてきた食器を整理機構920により積み重ねて整理し、所定枚数積み重ねられた食器を押上げ機構940により押上げて取出し可能とする食器整理装置900の一連の運転動作を説明する。
(A series of driving operation)
Next, referring to FIGS. 11 and 12, the dishes transferred from the washing apparatus 800 are stacked and sorted by the sorting mechanism 920, and a predetermined number of stacked dishes can be pushed up by the lifting mechanism 940 and taken out. A series of driving operations of the tableware management device 900 will be described.

食器Wは、ホルダー911の底面911a(図4参照、以下同じ)と両側面911bと傾斜面911cによりガイドされて移送される。なお、前記したように滑り部材としての樹脂プレートが接合されている傾斜面911cで食器Wを主として保持すればよく、食器Wは底面911aおよび両側面911bと接触せずにガイドされることとなる。   The tableware W is transported by being guided by the bottom surface 911a (see FIG. 4, the same applies hereinafter) of the holder 911 and the both side surfaces 911b and the inclined surface 911c. As described above, the tableware W may be mainly held by the inclined surface 911c to which the resin plate as the slide member is joined, and the tableware W is guided without being in contact with the bottom surface 911a and both side surfaces 911b. .

なお、押し板922とレバー923の各上面は面一とされ、押し板922が進出位置に移動している状態では、レバー923がホルダー911上に突出していて、そのときに食器シュート902から滑り落ちてくる食器Wは、レバー923上に一時的に乗り、押し板922が退避位置に戻るときに、ホルダー911上に落ちる。   The upper surfaces of the push plate 922 and the lever 923 are flush with each other, and when the push plate 922 is moved to the advanced position, the lever 923 protrudes above the holder 911 and slides from the tableware chute 902 at that time. The falling tableware W temporarily rides on the lever 923, and falls on the holder 911 when the push plate 922 returns to the retracted position.

第1保持爪916および第2保持爪917は、食器Wの移送方向に対面する側に三角形の緩やかな斜面となる緩斜面部916a、917a(図4および図5参照)が対峙し、緩斜面部916a、917aの背面側には急な斜面となる急斜面部916b、917bが対峙した三角形状とされ、バネ機構によりホルダー空間に突出付勢されている。   In the first holding claw 916 and the second holding claw 917, the gentle slope portions 916a and 917a (see FIGS. 4 and 5), which are gentle slopes of a triangle, face the side facing the transfer direction of the tableware W Steep slope portions 916b and 917b, which are steep slopes, are formed in a triangle shape facing each other on the back side of the portions 916a and 917a, and are urged into the holder space by a spring mechanism.

このため、第1保持爪916および第2保持爪917は、食器Wが押出されるときは、移送面から引っ込んで食器Wの通過を許容し、食器Wを整理位置P2、取出し位置P3に保持した後は、食器Wの重力が掛かっても引っ込むことがない。   Therefore, when the tableware W is extruded, the first holding claw 916 and the second holding claw 917 are retracted from the transfer surface to allow passage of the tableware W, and hold the tableware W in the sorting position P2 and the removal position P3. Even after the tableware W is subjected to gravity, it does not retract.

図11(a)〜図11(c)は、食器整理装置900による食器の整理動作および押上げ動作を時系列に示す。これは、上述の図8に示した食器整理装置900の運転方法を実行したときの動作に相当する。   11 (a) to 11 (c) show the arrangement operation and the lifting operation of the tableware by the tableware arranging device 900 in time series. This corresponds to the operation when the operation method of the tableware management apparatus 900 shown in FIG. 8 described above is executed.

洗浄装置800から搬送されてきた食器Wは、食器シュート902からホルダー911の下段の受入れ位置P1に起立姿勢で滑り落ちる。押し板922は、連続して往復動しており、ホルダー911の中段の食器Wの整理位置P2まで食器Wを1枚ずつ押出して下方から積み重ねて整理する。このとき、食器Wは、第1保持爪916、押出爪941(押出爪942a、942b、942c、942d)のバネ機構による突出付勢力に抗して押出される。   The tableware W transported from the cleaning device 800 slips from the tableware chute 902 to the lower receiving position P1 of the holder 911 in a standing posture. The push plate 922 continuously reciprocates, extrudes the dishes W one by one to a rear end position P 2 of the tableware W in the middle of the holder 911 and stacks them from below and arranges them. At this time, the tableware W is pushed against the projecting biasing force of the spring mechanism of the first holding claw 916 and the pushing claw 941 (pushing claws 942a, 942b, 942c, 942d).

押し板922は、食器Wを1枚ずつ押出して第1保持爪916に確実に保持させるため、第1保持爪916に保持される食器Wの移送方向の上流側となる食器Wの表面(開口面)が、第1保持爪916による保持位置より、所定の距離だけ移送方向の下流側(例えば略10mm)まで押出している。押し板922は、その後、退避位置に戻る。押し板922が退避位置に戻る際に、押出された食器Wは、移送方向の上流側へ所定の距離だけ戻り、第1保持爪916により保持されることとなる(図11(a)参照)。このとき食器Wは第1保持爪916の急斜面部916bにより保持されている。   The pushing plate 922 is a surface (opening of the tableware W on the upstream side in the transfer direction of the tableware W held by the first holding claw 916 so that the tableware W is pushed out one by one and held by the first holding claw 916 reliably. The surface) is pushed out to the downstream side (for example, approximately 10 mm) in the transfer direction by a predetermined distance from the holding position by the first holding claw 916. The push plate 922 then returns to the retracted position. When the push plate 922 returns to the retracted position, the pushed-out dish W is returned to the upstream side in the transfer direction by a predetermined distance, and is held by the first holding claw 916 (see FIG. 11A). . At this time, the tableware W is held by the steep slope portion 916 b of the first holding claw 916.

この整理動作は、整理位置P2に押出され整理された食器Wが所定枚数(図示は略しているが、例えば20枚)に達するまで繰返される(図11(a)および図11(b)参照)。このとき、押出爪941は待機位置にある。なお、第1保持爪916に加えて、待機位置にある押出爪941により、整理位置P2に押出され整理された食器Wを保持してもよい。   This arrangement operation is repeated until the number of dishes W which are pushed out and arranged at the arrangement position P2 reaches a predetermined number (for example, 20 sheets, although not shown) (see FIGS. 11A and 11B). . At this time, the pushing claw 941 is in the standby position. In addition to the first holding claws 916, the pushing claws 941 located at the standby position may hold the tableware W which has been pushed out and arranged to the arrangement position P2.

整理位置P2の食器Wが所定枚数に達したとき、押出爪941を1往復だけ往復動させ、所定枚数の食器全体を整理位置P2より上段の取出し位置P3に押出して押上げる。   When the number of dishes W at the rearranging position P2 reaches a predetermined number, the push-out claw 941 is reciprocated by one reciprocation to push out the entire predetermined number of dishes from the rearranging position P2 to the takeout position P3 at the upper stage.

押出爪941は、所定枚数の食器Wを押出して第2保持爪917に確実に保持させるため、第2保持爪917に所定枚数積み重ねた食器Wの移送方向の上流側となる最後尾の食器Wの表面(開口面)が、第2保持爪917による保持位置より、所定の距離だけ移送方向の下流側(例えば略10mm)まで押出されている。押出爪941は、その後、待機位置に戻る。押出爪941が待機位置に戻る際に、押出された所定枚数の食器Wは、移送方向の上流側へ所定の距離だけ戻り、第2保持爪917により保持されることとなる(図11(c)参照)。このとき食器Wは第2保持爪917の急斜面部917bにより保持されている。   The extruding claw 941 extrudes a predetermined number of dishes W and causes the second holding claw 917 to reliably hold it. The surface (opening surface) of the second holding claw 917 is extruded to the downstream side (for example, approximately 10 mm) in the transfer direction by a predetermined distance from the holding position by the second holding claw 917. The push-out claw 941 then returns to the standby position. When the push-out claw 941 returns to the standby position, the predetermined number of pushed-out dishes W return to the upstream side in the transfer direction by a predetermined distance, and are held by the second holding claw 917 (FIG. 11 (c )reference). At this time, the tableware W is held by the steep slope portion 917 b of the second holding claw 917.

押出爪941は、押し板922の往復動と干渉を起こすことなく円滑に往復動できるように構成されており、押出爪941が往復動する間にも、押し板922は連続的に往復動できる。   The pushing claw 941 is configured to be able to smoothly reciprocate without causing interference with the reciprocating movement of the pushing plate 922, and the pushing plate 922 can continuously reciprocate while the pushing claw 941 reciprocates. .

本実施形態では、食器Wの移送方向が斜め上方に向かうホルダー911上に食器Wの表面側を斜め下向きに積み重ねて整理するので、洗浄されて水滴が付着した食器Wであっても、食器W内に水滴が溜まることがなく、好都合である。   In this embodiment, since the front side of the tableware W is arranged by stacking the surface side of the tableware W obliquely downward on the holder 911 in which the transfer direction of the tableware W is directed obliquely upward, the tableware W is cleaned even if water droplets adhere. Water droplets do not accumulate inside, which is advantageous.

また、押出爪の駆動手段950の駆動を開始するタイミングは、所定枚数の最後となる食器Wが食器シュート902上を滑り落ち、ホルダー911に受入れられ、押し板922により整理位置P2へと押出されたタイミングとなる。このタイミングは、所定枚数の最後となる食器Wを食器センサー901で検知した信号を基準として、制御装置1000に有するタイマー等で最適に制御するものである。   Further, at the timing of starting the drive of the pushing claw driving means 950, the last set of tableware W slides down on the dish chute 902, is received by the holder 911 and is pushed by the push plate 922 to the organizing position P2. Timing. This timing is optimally controlled by a timer or the like provided in the control device 1000 based on a signal detected by the tableware sensor 901 as the last set of tableware W.

また、通常は食器シュート902を滑り落ちる食器Wを検知しているが、万が一食器整理装置900内での食器Wの滞留等が発生し、食器シュート902にも食器Wが滞留した場合、食器センサー901が食器Wを通常より長時間に亘って検知し続けることとなる。このようなときには、制御手段1000により警報を出し、食器Wが滞留していることを作業者に知らせることができる。   Moreover, although the tableware W which usually slides down the tableware chute 902 is detected, if the tableware W is retained etc. in the tableware organizing apparatus 900 and the tableware W stays in the tableware chute 902, the tableware sensor 901 Continues to detect the tableware W for a longer time than usual. In such a case, a warning can be issued by the control means 1000 to notify the worker that the tableware W is staying.

図12(a)〜図12(c)は、食器Wの整理動作および押上げ動作における押し板922と押出爪941の動作を時系列に示している。これは、上述の図11(a)〜図11(c)に対応し、説明は重複するので省く。   FIGS. 12 (a) to 12 (c) show the operation of the push plate 922 and the pushing claw 941 in the arranging operation and the pushing-up operation of the tableware W in time series. This corresponds to the above-mentioned FIG. 11 (a) to FIG. 11 (c), and the description is omitted because it is redundant.

このような食器の整理装置の運転動作により、所定枚数になった食器Wの押出爪941による押上げ動作中にも、洗浄装置800から連続して搬送されてくる後続の食器Wの押し板922による整理動作を中断することなく同時並行的に行うことができる。整理動作を連続して実施しながら、押上げ動作を実施することができるものである。
