[發明效果] 如上所述，根據本發明，由於可無須設置習知的分離 銷地，利用吸引力與定時（timing )來執行工件的分離供 給，因此可消除有關分離銷彎折和組裝的問題，並可實現 連續的裝置運轉，且達成高速化。此外，由不需設置遮罩 ，故不會產生工件的阻塞，據此，由於不需要復原裝置， 能單純地分離供給安定的工件，而能降低製品的成本。 【實施方式】 以下，參考圖面說明本發明的實施型態。 第1圖爲顯示本發明工件搬運系統之一種實施型態的 俯視圖，第2圖爲顯示工件搬運系統的前視圖，第3a圖 爲線性饋送器於正常狀態下的剖面放大圖，第3 b圖爲線 性饋送器於異常狀態下的剖面放大圖，此外第4a〜c圖是 供給饋送器的說明圖，第5圖爲顯示分離溜槽的前視圖， 第6圖爲顯示工件裝塡孔的側視圖，第7圖爲顯示工件排 出孔的側視圖。 在第1、2圖中，工件搬運系統1具備··設成垂直的 平台基座2;和配置於平台基座2之垂直面2a上設成可於 水平迴轉軸3a周圍自由間歇轉動，且於外周具有複數個 C字型工件收納溝（工件收納部）4之工件搬運手段的搬 運平台3;和配置成垂直於搬運平台3，且作爲使工件W 彼此抵接而連續供給至工件收納溝4之工件供給手段的線 性饋送器6 ;及設於線性饋送器6與搬運平台3之間’逐 -9 - (6) (6)1278257, 一分由線性饋送器6所供給之工件W的分離溜槽。 上述的線性饋送器6是由：將工件W供給至搬運平 台3的供給饋送器6a、及將供給饋送器6a或搬運平台3 所排出的工件W回送至供給饋送器6a上游端的回收饋送 器6b所形成，線性饋送器6是設成垂直於搬運平台3。此 外，分離溜槽7是被挾持於供給饋送器6a下游端與搬運 平台3之間。 此外，回收饋送器6b，是於供給饋送器6a的下方配 置成平行於供給饋送器6a。 如第3 a、b圖所示，供給饋送器6a的工件搬運通路 具有第IV型溝9。該第IV型溝9，是具有如第4a圖所示 之工件正反面判別手段的功能，其具備長邊9a與短邊9b ，第1V型溝9的內角形成直角，而長邊9a的斜角對水平 面形成45度。如第4b圖所示，第IV型溝9之短邊9b的 高度尺寸L，是形成大於工件W之角落部R的半徑。如第 4c圖所示，一旦工件未取得正常的搬運位置（工件的正反 面顛倒）時，工件W之重心G的垂線將位於較第1V型溝 9之短邊9b棱線9c更外側的位置。在第4c圖中，尺寸X 爲0以上。如此一來，一旦工件在供給饋送器6a內無法 取得正確的搬運位置（工件正反面異常時），供給饋送器 6a內的工件W將越過短邊9b滑落至回收饋送器6b後回 送。 在本實施型態中如第3 a、b圖所示，供給饋送器6a 之第IV型溝9的長邊9a，是對應於朝回收饋送器6b側 -10- (7) 1278257· 傾斜的傾斜面，而短邊9b是位於回收饋送器6b側。 此外，如第5圖所示之分離溜槽7的搬運面，具有對 應於供給饋送器6a之第IV型溝的第2V型溝15。該第 2V型溝15是由：與第IV型溝9之長邊9a位於相同平面 的長邊1 5 a、及與第1V型溝9之短邊9b位於相同平面的 短邊15b所形成。該第2V型溝15於搬運平台3停止時， 其長邊1 5 a與設於搬運平台3之周緣部的C字狀工件收納 溝4的底面一致，且第2V型溝1 5的短邊1 5b與工件收納 溝4之迴轉方向的後側面一致。 如第1、6圖所示，分離溜槽7之第2V型溝1 5的長 邊15a，於供給饋送器6a側設置貫穿分離溜槽7的吸引孔 1 〇，此外，於搬運平台3側設有噴射孔1 1。吸引孔10與 噴射孔1 1，分別經由圖面中未顯示的空氣控制手段連通真 空產生源及壓縮空氣產生源。 如第1、5、6圖所示，面向第2 V型溝15，設有貫穿 平台基座2的工件裝塡孔12，該工件裝塡孔12連通於圖 面中未顯示的真空產生源，而使該工件裝塡孔12形成長 時間的負壓狀態。 此外，如第1、2、7圖所示，在從工件供給收段6起 一個工件收納溝4之節具以上的位置，貫穿分離溜槽7設 置工件偵測感應器8的光線發射器8 a，面對光向發射器 8 a，從分離溜槽7起至少保持工件W厚度以上的距離，設 置光線接收器8b。在分離溜槽7中，工件偵測感應器8的 光線發射器8a是設在距離供給饋送器6a —個工件收納溝 -11 - (8) 1278257 4之節距以上的上、下游側。 如第1、7圖所示，面對工件偵測感應器8，貫穿平 基座2設置工件排出孔1 3，該工件排出孔1 3經由圖面 未顯示的空氣控制手段連通於壓縮空氣產生源。而裝塡 第2圖之工件收納溝4的工件W，受到圖面中未顯示之 引手段長時間的吸引，進而形成迴轉搬運。 本發明所使用的工件W，最好是具有安定部（以下 爲安定底面）。舉例來說，倘若工件W的剖面爲長方 時最好具有長邊的面，倘若剖面爲奇怪的形狀時最好具 安定面（第3圖之工件中的長邊面），該安定面形成 1 V型溝9之長邊9a的面側後被搬運。 接下來針對形成上述結構之本實施形態的作用進行 明。 在第1圖中，線性饋送器6，譬如是由振動式的線 饋送器所形成，供給饋送器6a是以搬運平台3作爲下 側’一邊使具有安定面（譬如長方形剖面之長邊20a的 )的工件W間彼此抵接，一邊形成整列的搬運，一方 ’回收饋送器6b是以搬運平台3側作爲上游來搬運工 W，而使回饋饋送器6b上的工件W回送到供給饋送器 的上游。 當工件W被搬運到線性饋送器6之供給饋送器6a 時，如第3 a圖及第4b圖所示，作爲工件W剖面之安定 面的長邊20a之相對的面，抵接於供給饋送器6a之第 型溝9的長邊9a，工件W的角落部R抵接於第1V型清 台 中 於 吸 稱 形 有 第 說 性 游 面 面 件 6 a 上 底 IV I 9 -12- (9) (9)1278257 的短邊9b。如上所述的工件W，其正、反面形成正常狀 態的搬運姿勢。在上述的場合中，工件w由於其重心G 位於第1 V型溝9的長邊9a側’故能安定搬運。 另外，如第3b圖及第4c圖所示，在工件W之剖面的 長邊20a抵接於短邊9b側之正反面顛倒的狀態下，重心 G的垂線從稜線部9c脫離。因此工件W導向供給饋送器 6a之第1 V型溝9的外側而被排出，並於滑落至回收饋送 器6b上之後再次被供給至供給饋送器6a的上游側。 接著，形成正常狀態之搬運姿勢的工件W，被搬運至 供給饋送器6a的下游側，並在分離溜槽7的上游側被吸 引孔1 〇的負壓所吸引而限制其移動。 在本實施形態中，由控制部1 a所控制的分離溜槽7 之吸引孔10的負壓吸引/停止；噴射孔11之分離空氣的 噴射/停止；及搬運平台3的間歇轉動/停止定時（timing )均顯示於第8圖。 搬運平台3的迴轉過程中，工件W被吸引孔10分離 吸引而保持於分離溜槽7上，同時假設在停止的工件W 之前具有不良工件W，由噴射孔1 1噴射分離空氣將殘存 的工件W從分離溜槽7排除。稍後停止搬運平台3。在該 場合中’來自於噴射孔1 1的分離空氣，是從搬運平台3 快開始迴轉之前開始噴射。此外，搬運平台3停止迴轉之 後馬上停止噴射孔1 1的噴射與吸引孔1 0的吸引。接著如 第0圖所示，被吸引孔1 〇所吸引而停留於分離溜槽7的 前端工件W，將被停止狀態下位於搬運平台3之工件收納 -13- (10) (10)1278257 溝4背面的平台基座2之工件裝塡孔1 2所吸引，裝塡入 工件收納溝4。 在該場合中，雖然工件裝塡孔1 2形成長時間的負壓 化，但由於工件W的吸引是當搬運平台3之工件收納溝4 與裝塡吸引孔1 2形成相對時執行，故工件W裝塡於工件 收納溝4的定時（t i m i n g )，是如第8圖所不仰賴於搬運 平台3的位置。 當分離溜槽7上的前端工件Wi裝塡於工件收納溝4 時，吸引孔1 〇再度形成負壓，後續的工件W2將於分離溜 槽7上被分離吸引後停止，而與前端工件Wi形成分離。 上述的動作，無須利用確認感應器進行確認，而是採 用全部經安排的定時（t i m i n g )執行。因此，也考慮到誤 使後續工件W2緊接於前端工件Wi通過吸引孔1 0的狀況 。在上述場合中，在搬運平台3停止之前，利用噴射孔11 的噴射空氣而從分離溜槽7排出後續的工件W2使其掉落 至回收饋送器6b。 另外如第7圖所示，當裝塡於工件收納溝4之工件W 的裝塡姿勢不完整，而導致部分的工件W從工件收納溝4 突出時，將由工件偵測感應器8偵測出該工件W。接著根 據工件偵測感應器8的訊號，以控制部1 a的指令對工件 排出孔1 3噴出壓縮空氣。此時，工件w將從工件收納溝 4排出’並經由分離溜槽7的外周曲面掉落至回收饋送器 6b ° 如以上所述，根據本實施形態，可不致產生工件阻塞 -14- (11) (11)1278257 地逐一使工件分離，並一邊確實地將工件裝塡入搬運平台 的工件收納溝。 此外，本發明的工件搬運系統，亦可用於如包裝（ taping )裝置之類具有間歇迴轉之搬運平台的裝置。 此外，雖然第IV型溝的長邊9a是以45度作爲範例 ，但本發明卻不侷限於此，亦可配合工件W的形狀，使 長邊9a對水平面形成35度以上角度而使工件容易從短邊 9b掉落即可，長邊9a的斜角並未限定爲45度。 此外，雖然圖面中未顯示，但亦可藉由在工件收納溝 4設置確認感應器的方式來省略排出孔1 3。上述場合中的 感應器，除了光學感應器之外，亦可採用負壓感應器或影 像處理之類的方法，只要是能確認工件W是否以完整的 姿勢裝塡於工件收納溝內的裝置即可，該感應器的種類並 無限制。 此外，第IV型溝9與第2V型溝15的長邊9a、15a 、短邊9b、15b的尺寸可根據工件W的形狀變更成可確 實執行上述動作的尺寸。 【圖式簡單說明】 第1圖：爲顯示本發明工件搬運系統之一種實施型態 的俯視圖。 第2圖：爲顯示本發明工件搬運系統之一種實施型態 的前視圖。 第3圖：爲顯示線性饋送器的圖。 -15- (12) (12)1278257, 第4圖：爲顯示線性饋送器之供給饋送器的圖。 第5圖：爲顯示分離溜槽的前視圖。 第6圖：爲顯示工件裝塡孔的側視圖。 第7圖：爲顯示工件排出孔的側視圖。 第8圖：顯示本發明之作用的時序圖表。 第9圖：顯示傳統工件搬運系統的圖。 【主要元件符號說明】 1 :工件搬運系統 2 :平台基座 3 :搬運平台 4 :工件收納溝 6 :線性饋送器 6 a :供應饋送器 6b :回收饋送器 7 :分離溜槽 8 :工件偵測感應器 8 a :光線發射器 8b :光線接收器 9 :第1V型溝 9a :長邊 9b :端邊 9c :稜線部 1 〇 :吸引孔 16- (13) (13)1278257,[Effect of the Invention] As described above, according to the present invention, since the separation and supply of the workpiece can be performed by the attraction force and the timing without the need to provide the conventional separation pin, the problem of the folding and assembly of the separation pin can be eliminated. It can realize continuous device operation and achieve high speed. Further, since the mask is not required, the clogging of the workpiece does not occur, and accordingly, since the restoration device is not required, the stable supply of the workpiece can be separated, and the cost of the product can be reduced. [Embodiment] Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a plan view showing an embodiment of the workpiece handling system of the present invention, FIG. 2 is a front view showing the workpiece handling system, and FIG. 3a is an enlarged cross-sectional view of the linear feeder in a normal state, FIG. 3b. It is an enlarged view of the cross section of the linear feeder in an abnormal state, and in addition, 4a to cth are explanatory views of the supply feeder, Fig. 5 is a front view showing the separation chute, and Fig. 6 is a side view showing the workpiece mounting hole. Figure 7 is a side view showing the workpiece discharge hole. In the first and second figures, the workpiece transport system 1 is provided with a vertical platform base 2; and the vertical surface 2a disposed on the platform base 2 is provided to be freely intermittently rotatable around the horizontal rotary shaft 3a, and a transport platform 3 having a plurality of C-shaped workpiece storage grooves (workpiece accommodating portions) 4 for the workpiece transporting means on the outer circumference; and arranged perpendicular to the transport platform 3, and continuously feeding the workpieces W to the workpiece storage grooves 4 is a linear feeder 6 of the workpiece supply means; and is disposed between the linear feeder 6 and the transport platform 3 'by -9 - (6) (6) 1278257, one part of the workpiece W supplied by the linear feeder 6 Separate the chute. The above-described linear feeder 6 is composed of a supply feeder 6a that supplies the workpiece W to the conveyance platform 3, and a recovery feeder 6b that feeds the workpiece W discharged from the supply feeder 6a or the conveyance platform 3 to the upstream end of the supply feeder 6a. Formed, the linear feeder 6 is disposed perpendicular to the transport platform 3. Further, the separation chute 7 is held between the downstream end of the supply feeder 6a and the transfer platform 3. Further, the recovery feeder 6b is disposed below the supply feeder 6a so as to be parallel to the supply feeder 6a. As shown in Figs. 3a and 3b, the workpiece conveyance path of the feed feeder 6a has the IV-shaped groove 9. The fourth type groove 9 has a function of a front and back surface discrimination means of the workpiece as shown in Fig. 4a, and has a long side 9a and a short side 9b. The inner corner of the first V-shaped groove 9 forms a right angle, and the long side 9a The bevel forms 45 degrees to the horizontal. As shown in Fig. 4b, the height dimension L of the short side 9b of the IV-shaped groove 9 is a radius which is larger than the corner portion R of the workpiece W. As shown in Fig. 4c, when the workpiece does not have a normal conveyance position (the front and back sides of the workpiece are reversed), the perpendicular line of the center of gravity G of the workpiece W will be located outside the ridge 9c of the short side 9b of the first V-shaped groove 9. . In Fig. 4c, the dimension X is 0 or more. As a result, once the workpiece is unable to obtain the correct conveyance position in the supply feeder 6a (when the front and back of the workpiece are abnormal), the workpiece W in the supply feeder 6a will slide back to the recovery feeder 6b beyond the short side 9b and be fed back. In the present embodiment, as shown in Figs. 3a and 2b, the long side 9a of the IV-shaped groove 9 of the supply feeder 6a corresponds to the inclination toward the recovery feeder 6b side -10 (7) 1278257. The inclined surface 9b is located on the side of the recovery feeder 6b. Further, the conveying surface of the separation chute 7 shown in Fig. 5 has a second V-shaped groove 15 corresponding to the IV-shaped groove of the feeding feeder 6a. The second V-shaped groove 15 is formed by a long side 15a which is located on the same plane as the long side 9a of the IV-shaped groove 9, and a short side 15b which is located on the same plane as the short side 9b of the first V-shaped groove 9. When the transport platform 3 is stopped, the long side 1 5 a of the second V-shaped groove 15 coincides with the bottom surface of the C-shaped workpiece storage groove 4 provided at the peripheral edge portion of the transport platform 3, and the short side of the second V-shaped groove 15 1 5b coincides with the rear side surface of the workpiece storage groove 4 in the direction of rotation. As shown in the first and sixth figures, the long side 15a of the second V-shaped groove 15 of the separation chute 7 is provided with a suction hole 1 through the separation chute 7 on the supply feeder 6a side, and is provided on the conveyance platform 3 side. Spray hole 1 1. The suction hole 10 and the injection hole 11 are connected to the vacuum generation source and the compressed air generation source via air control means not shown in the drawing, respectively. As shown in the first, fifth, and sixth figures, the second V-shaped groove 15 is provided with a workpiece mounting hole 12 penetrating the platform base 2, and the workpiece mounting hole 12 communicates with a vacuum generating source not shown in the drawing. The workpiece mounting hole 12 is formed into a negative pressure state for a long time. Further, as shown in the first, second, and seventh figures, the light emitter 8a of the workpiece detecting sensor 8 is disposed through the separation chute 7 at a position above the knot of the workpiece receiving groove 4 from the workpiece supply receiving section 6. The light receiver 8b is disposed facing the light to the emitter 8a from the separation chute 7 at least a distance greater than the thickness of the workpiece W. In the separation chute 7, the light emitter 8a of the workpiece detecting sensor 8 is provided on the upper and lower sides of the pitch of the supply feeder 6a from the workpiece receiving grooves -11 - (8) 1278257 4 . As shown in FIGS. 1 and 7, facing the workpiece detecting sensor 8, a workpiece discharge hole 13 is provided through the flat base 2, and the workpiece discharge hole 13 is connected to the compressed air via an air control means not shown in the drawing. source. On the other hand, the workpiece W attached to the workpiece storage groove 4 of Fig. 2 is sucked for a long time by means of a guide which is not shown in the drawing, and further forms a rotary conveyance. The workpiece W used in the present invention preferably has a stabilizer (hereinafter, a stable bottom surface). For example, if the cross section of the workpiece W is a rectangular shape, it is preferable to have a long side surface. If the cross section is a strange shape, it is preferable to have a stable surface (the long side surface in the workpiece of FIG. 3), and the stabilizer surface is formed. The surface side of the long side 9a of the 1 V-shaped groove 9 is conveyed. Next, the action of the present embodiment for forming the above structure will be described. In Fig. 1, the linear feeder 6, for example, is formed by a vibrating wire feeder, and the feeding feeder 6a is a lower side of the conveying platform 3, and has a stabilizer (such as a long side 20a of a rectangular cross section). The workpieces W are in contact with each other to form an entire row of conveyance, and the one 'recycling feeder 6b is the upstream transporting device W on the conveying platform 3 side, and the workpiece W on the feedback feeding device 6b is returned to the feeding feeder. Upstream. When the workpiece W is transported to the feed feeder 6a of the linear feeder 6, as shown in Figs. 3a and 4b, the opposite side of the long side 20a which is the stabilizer surface of the cross section of the workpiece W abuts against the feed feed. The long side 9a of the first groove 9 of the device 6a, the corner portion R of the workpiece W abuts on the first V-shaped cleaning table, and the upper surface of the first surface type surface member 6a is im I IV -12- (9 ) (9) Short side 9b of 1278257. The workpiece W as described above has a normal and reverse conveyance posture in the normal state. In the above case, the workpiece w can be stably transported because its center of gravity G is located on the long side 9a side of the first V-shaped groove 9. Further, as shown in Figs. 3b and 4c, in a state in which the long side 20a of the cross section of the workpiece W abuts against the front side of the short side 9b, the perpendicular line of the center of gravity G is separated from the ridge line portion 9c. Therefore, the workpiece W is guided to the outside of the first V-shaped groove 9 of the supply feeder 6a, and is discharged to the upstream side of the supply feeder 6a after being slid down onto the recovery feeder 6b. Then, the workpiece W forming the normal conveyance posture is conveyed to the downstream side of the supply feeder 6a, and is attracted by the negative pressure of the suction hole 1 上游 on the upstream side of the separation chute 7 to restrict the movement thereof. In the present embodiment, suction/stop of the suction pressure of the suction hole 10 of the separation chute 7 controlled by the control unit 1a; injection/stop of the separation air of the injection hole 11; and intermittent rotation/stop timing of the conveyance platform 3 ( Timings are shown in Figure 8. During the turning of the transport platform 3, the workpiece W is separated and attracted by the suction hole 10 and held on the separation chute 7, and it is assumed that there is a defective workpiece W before the stopped workpiece W, and the residual workpiece W is ejected by the injection hole 11 Excluded from the separation chute 7. Stop transporting platform 3 later. In this case, the separation air from the injection hole 11 is started before the conveyance platform 3 starts to rotate. Further, immediately after the conveyance platform 3 stops rotating, the injection of the injection holes 1 1 and the suction of the suction holes 10 are stopped. Then, as shown in Fig. 0, the workpiece W which is attracted by the suction hole 1 停留 and stays at the front end of the separation chute 7 is placed in the workpiece of the conveyance platform 3 in the stopped state. -13 (10) (10) 1278257 Groove 4 The workpiece mounting hole 12 of the platform base 2 on the back side is attracted to the workpiece receiving groove 4. In this case, although the workpiece mounting hole 12 is formed to have a negative pressure for a long period of time, since the workpiece W is sucked when the workpiece receiving groove 4 of the conveying platform 3 is opposed to the mounting suction hole 12, the workpiece is processed. The timing at which the W is attached to the workpiece storage groove 4 is a position that does not depend on the conveyance platform 3 as shown in Fig. 8. When the front end workpiece Wi on the separation chute 7 is mounted on the workpiece receiving groove 4, the suction hole 1 〇 again forms a negative pressure, and the subsequent workpiece W2 is separated and attracted by the separation chute 7, and is stopped to form a separation from the front end workpiece Wi. . The above actions are performed without using the acknowledgment sensor, but are performed using all of the scheduled timings (t i m i n g ). Therefore, it is also considered that the subsequent workpiece W2 is mistakenly connected to the front end workpiece Wi through the suction hole 10. In the above case, before the conveyance platform 3 is stopped, the subsequent workpiece W2 is discharged from the separation chute 7 by the injection air of the injection hole 11 to be dropped to the recovery feeder 6b. Further, as shown in Fig. 7, when the mounting posture of the workpiece W attached to the workpiece receiving groove 4 is incomplete, and part of the workpiece W protrudes from the workpiece receiving groove 4, it is detected by the workpiece detecting sensor 8. The workpiece W. Then, based on the signal of the workpiece detecting sensor 8, the compressed air is ejected to the workpiece discharge hole 13 by the command of the control unit 1a. At this time, the workpiece w is discharged from the workpiece receiving groove 4 and dropped to the recovery feeder 6b via the outer peripheral curved surface of the separation chute 7. As described above, according to the present embodiment, the workpiece can be prevented from being blocked-14- (11) (11) 1278257 The workpieces are separated one by one, and the workpiece is surely loaded into the workpiece storage groove of the transport platform. Further, the workpiece handling system of the present invention can also be applied to a device having an intermittently rotating handling platform such as a taping device. Further, although the long side 9a of the IV-shaped groove is exemplified by 45 degrees, the present invention is not limited thereto, and the shape of the workpiece W may be matched so that the long side 9a forms an angle of 35 degrees or more with respect to the horizontal plane to make the workpiece easy. It can be dropped from the short side 9b, and the oblique angle of the long side 9a is not limited to 45 degrees. Further, although not shown in the drawing, the discharge hole 13 may be omitted by providing a confirmation sensor in the workpiece storage groove 4. In the above-mentioned sensor, in addition to the optical sensor, a method such as a negative pressure sensor or image processing may be employed, as long as it is a device capable of confirming whether or not the workpiece W is mounted in the workpiece storage groove in a complete posture. Yes, there is no limit to the type of sensor. Further, the dimensions of the long sides 9a, 15a and the short sides 9b, 15b of the IV-shaped groove 9 and the second V-shaped groove 15 can be changed according to the shape of the workpiece W to a size at which the above-described operation can be surely performed.
