[發明所欲解決之問題][The problem to be solved by the invention]

以往，已知為了於鍍覆槽內使長條工件移動，而於鍍覆槽之壁形成有用於送入長條工件之槽縫，自該槽縫中鍍覆液漏出，但對應該漏出量而設定槽縫與長條工件之間的間隙。又，如專利文獻2及3所揭示，於工件之搬送方向入口側及出口側設置用以減少液體漏出的滾筒，但入口側之搬送方向與漏出時之液體流動所產生之力為逆向，因此滾筒之旋轉速度與工件之搬送速度產生差距，故而因工件與滾筒之摩擦，於工件較柔軟之情形時會於工件表面產生損傷之不良情況。In the past, it is known that in order to move the long workpiece in the coating tank, a slot for feeding the long workpiece is formed in the wall of the coating tank, and the coating liquid leaks from the slot, but it corresponds to the amount of leakage And set the gap between the slot and the long workpiece. In addition, as disclosed in Patent Documents 2 and 3, rollers are provided on the inlet side and outlet side of the workpiece conveying direction to reduce liquid leakage, but the conveying direction on the inlet side and the force generated by the liquid flow at the time of leakage are reversed, so There is a gap between the rotation speed of the roller and the conveying speed of the workpiece. Therefore, due to the friction between the workpiece and the roller, the surface of the workpiece will be damaged when the workpiece is soft.

又，於為了消除上述之不良情況，而擴大滾筒間之間隙之情形時，鍍覆液之漏出量變多，產生追加鍍覆液或對供循環之供給泵造成負擔之不良情況，又，於由彈性材料形成滾筒且將間隙設為0之情形時，漏出量減少，但施加於滾筒之力與工件之移動方向和鍍覆液之漏出方向為逆方向，因此滾筒之旋轉變得不滑順，故而產生卡在工件之接縫之不良情況，又，由於將工件由兩根滾筒夾入，因此成為使工件蛇行之主要原因，據此產生搬送高度變化之不良情況。In addition, when the gap between the rollers is enlarged in order to eliminate the above-mentioned disadvantages, the leakage of the plating solution will increase, resulting in additional plating solution or a burden on the circulating supply pump. When the elastic material forms the roller and the gap is set to 0, the amount of leakage is reduced, but the force applied to the roller is opposite to the direction of movement of the workpiece and the direction of leakage of the plating solution, so the rotation of the roller becomes unsmooth. As a result, the problem of jamming in the seam of the workpiece occurs. In addition, since the workpiece is clamped by the two rollers, it becomes the main cause of the workpiece snaking, and accordingly, the problem of changing the conveying height occurs.

進而最近，工件自身變得更薄且柔軟精緻，進而工件巾亦漸漸變大，因此產生鍍覆液之漏出量增加，滾筒之旋轉不良時常發生等不良情況。進而於夾持搬送工件之情形時，有時會產生工件下側無法跟上而產生折皺之不良情況。Furthermore, recently, the workpiece itself has become thinner and softer and more delicate, and the workpiece towel has gradually become larger. As a result, the leakage of the plating solution has increased, and the rotation of the drum has often been defective. Furthermore, when the workpiece is clamped and transported, sometimes the underside of the workpiece cannot be kept up and wrinkles are generated.

因此，本發明提供一種導引滾筒裝置，將來自鍍覆槽、洗滌槽等之浸漬槽之液體漏出量減至最少，可防止導引工件之滾筒造成的對工件的傷害。 [解決問題之技術手段]Therefore, the present invention provides a guide roller device that minimizes the leakage of liquid from the immersion tank of the plating tank, washing tank, etc., and can prevent damage to the workpiece caused by the roller that guides the workpiece. [Technical means to solve the problem]

本發明係關於一種導引滾筒裝置，於在如鍍覆槽、洗滌槽之浸漬槽中，形成工件送入槽縫部、和工件送出槽縫部，並且將一對工件導引滾筒分別設於工件送入槽縫部及工件送出槽縫部之外側的鍍覆裝置中，使前述一對工件導引滾筒之旋轉速度對應前述工件之搬送速度，且於前述一對工件導引滾筒與前述工件之間設置既定之間隙。此外，較佳為：前述工件導引滾筒，例如藉由馬達而旋轉，並且前述馬達係藉由控制器單元並基於工件之搬送速度、來自浸漬槽之液體漏出量、工件導引滾筒與工件之間之滑移量等的參數而被控制。The present invention relates to a guide roller device. In a dipping tank such as a plating tank and a washing tank, a workpiece feeding slot portion and a workpiece sending slot portion are formed, and a pair of workpiece guide rollers are respectively arranged on the workpiece feeding slot. In the plating device outside the slot in and the workpiece out of the slot, the rotation speed of the pair of workpiece guide rollers corresponds to the conveying speed of the workpiece, and a predetermined set between the pair of workpiece guide rollers and the workpiece的 gap. In addition, it is preferable that the workpiece guide roller is rotated by, for example, a motor, and the motor is based on the conveying speed of the workpiece by the controller unit, the amount of liquid leakage from the immersion tank, and the difference between the workpiece guide roller and the workpiece. Parameters such as the amount of slip between them are controlled.

又，較佳為，前述工件導引滾筒之旋轉速度係以工件導引滾筒之外周之周速度與前述工件之搬送速度一致之方式被設定。Furthermore, it is preferable that the rotation speed of the workpiece guide roller is set in such a way that the peripheral speed of the outer circumference of the workpiece guide roller coincides with the conveying speed of the workpiece.

如上所述，工件通過形成於浸漬槽之工件送入槽縫部而被送入浸漬槽內，於浸漬槽內被處理後，被送出至通過工件送出槽縫部之浸漬槽外而移動至下一步驟，但配置於工件送入槽縫部之上游側的一對工件導引滾筒，以對應工件之搬送速度的旋轉速度旋轉，由於工件導引滾筒之外周之周速度與工件之搬送速度一致，因此可將於工件導引滾筒與工件之間流入之漏出液產生的往反方向之力強制地抵消，並且藉此就算於工件與滾筒接觸之情形時，由於兩者之移動速度一致，因此可防止對工件之損傷產生。進而藉此，也可抑制來自工件送入槽縫部及工件送出槽縫部之液漏量。As described above, the workpiece is sent into the immersion tank through the workpiece formed in the immersion tank and sent into the slot. After being processed in the immersion tank, it is sent out of the immersion tank through the workpiece delivery slot and moves to the next step. , But the pair of workpiece guide rollers arranged on the upstream side of the workpiece feeding slot portion rotates at a rotation speed corresponding to the conveying speed of the workpiece. Since the peripheral speed of the workpiece guide roller is consistent with the conveying speed of the workpiece, it can be The force in the opposite direction generated by the leakage liquid flowing in between the workpiece guide roller and the workpiece is forcibly offset, and even when the workpiece is in contact with the roller, the moving speed of the two is the same, so it can prevent Damage to the workpiece occurs. Furthermore, by this, the amount of liquid leakage from the workpiece feeding slot and the workpiece feeding slot can also be suppressed.

又，配置於工件送出槽縫部之下游側的一對工件導引滾筒，以與工件之搬送速度相對應之旋轉速度旋轉，工件導引滾筒之外周之周速度與工件之搬送速度一致，因此即使藉由自浸漬槽流出之液體對工件施加往搬送方向之力，亦藉由工件導引滾筒而工件之搬送速度保持一定，因此配置於該工件送出槽縫部之下游側的一對工件導引滾筒中，即使於工件與滾筒接觸之情形，亦由於兩者之移動速度一致，因此可防止對工件之損傷。 [發明之效果]In addition, a pair of workpiece guide rollers arranged on the downstream side of the workpiece delivery slot are rotated at a rotation speed corresponding to the conveying speed of the workpiece, and the peripheral speed of the workpiece guide roller is consistent with the conveying speed of the workpiece. The liquid flowing from the immersion tank exerts force on the workpiece in the conveying direction, and the conveying speed of the workpiece is kept constant by the workpiece guide roller. Therefore, a pair of workpiece guide rollers are arranged on the downstream side of the workpiece delivery slot. Among them, even when the workpiece is in contact with the roller, since the moving speed of the two is the same, the damage to the workpiece can be prevented. [Effects of Invention]

根據本發明，以使工件導引滾筒之外周之周速度與工件之搬送速度一致之方式，使工件導引滾筒強制地旋轉，因此可抑制因自浸漬槽漏出之液體而對工件施加之力所產生之影響，並且可防止由此產生的對工件之損傷的產生。進而藉此，亦可抑制來自用以將工件送入/送出之槽縫部之液漏量。According to the present invention, the workpiece guide roller is forced to rotate in such a way that the peripheral speed of the workpiece guide roller coincides with the conveying speed of the workpiece, so that the force applied to the workpiece due to the liquid leaking from the immersion tank can be suppressed. The impact can be produced, and can prevent the resulting damage to the workpiece. Furthermore, it is also possible to suppress the amount of liquid leakage from the slot portion used to feed in/out the workpiece.

以下，針對本發明之實施例，依照圖式進行說明。 [實施例]Hereinafter, the embodiments of the present invention will be described in accordance with the drawings. [Example]

本發明之鍍覆裝置，例如於如圖1至圖3所示之鍍覆槽、洗滌槽之浸漬槽1，形成有工件送入槽縫部2、工件送出槽縫部3，於工件送入槽縫部2之上游側設置上游側工件導引滾筒4、5，於工件送出槽縫部3之下游側設置下游側工件導引滾筒6、7。藉此，由未圖示之搬送機構垂直地保持且以既定之搬送速度Ts被搬送之工件10，自工件送入槽縫部2被往浸漬槽1內送入，進行鍍覆或洗滌等之處理後，自工件送出槽縫部3往下一步驟搬送。The plating device of the present invention, for example, in the dipping tank 1 of the plating tank and washing tank as shown in Figs. 1 to 3, a workpiece feeding slot 2 and a workpiece sending slot 3 are formed, and the workpiece is fed into the slot 1 The upstream side of 2 is provided with upstream side workpiece guide rollers 4 and 5, and the downstream side of the workpiece delivery slot 3 is provided with downstream side workpiece guide rollers 6,7. As a result, the workpiece 10 held vertically by a transport mechanism not shown and transported at a predetermined transport speed Ts is transported from the workpiece feed slot 2 into the dipping tank 1 for plating or washing. After that, the workpiece is sent out of the slot 3 and is transported to the next step.

又，於圖1(a)所示之鍍覆裝置中，前述工件導引滾筒4、5、6、7分別經由電動馬達8與傳遞機構9連結而被驅動旋轉。又，於圖1(b)所示之鍍覆裝置中，前述工件導引滾筒4、6，藉由配置於單側之一個電動馬達8與傳遞機構9而旋轉，對應於工件導引滾筒4、6之工件導引滾筒5、7藉由連結齒輪9a連動而被驅動旋轉。進而，電動馬達8藉由未圖示之控制器單元而被控制。該控制器單元基於前述工件10之搬送速度Ts設定前述工件導引滾筒4、5、6、7之旋轉速度Rs，尤其以使工件導引滾筒4、5、6、7之外周之周速度與前述工件10之搬送速度Ts相同之方式設定。此外，如圖1(a)所示，於將工件導引滾筒4、5、6、7以各自之電動馬達8驅動之情形時，可獨立地控制調整工件導引滾筒之上游側及下游側之平衡、及左右之工件導引滾筒之平衡。又，如圖1(b)所示，使左右之工件導引滾筒藉由連結齒輪9a連動之情形時，可獨立地調整工件導引滾筒之上游側及下游側之平衡，並且可使電動馬達8之數量減少。Furthermore, in the plating apparatus shown in FIG. 1(a), the aforementioned workpiece guide rollers 4, 5, 6, 7 are connected to a transmission mechanism 9 via an electric motor 8 to be driven to rotate. Moreover, in the plating apparatus shown in FIG. 1(b), the aforementioned workpiece guide rollers 4, 6 are rotated by an electric motor 8 and a transmission mechanism 9 arranged on one side, corresponding to the workpiece guide roller 4 The workpiece guide rollers 5 and 7 of, 6 are driven to rotate by the linkage gear 9a. Furthermore, the electric motor 8 is controlled by a controller unit not shown. The controller unit sets the rotation speed Rs of the workpiece guide rollers 4, 5, 6, and 7 based on the conveying speed Ts of the workpiece 10, especially so that the peripheral speed of the workpiece guide rollers 4, 5, 6, 7 and The conveying speed Ts of the aforementioned workpiece 10 is set in the same manner. In addition, as shown in Figure 1(a), when the workpiece guide rollers 4, 5, 6, and 7 are driven by their respective electric motors 8, the upstream and downstream sides of the workpiece guide rollers can be independently controlled and adjusted The balance, and the balance of the left and right workpiece guide rollers. Moreover, as shown in Figure 1(b), when the left and right workpiece guide rollers are linked by the connecting gear 9a, the balance between the upstream and downstream sides of the workpiece guide roller can be adjusted independently, and the electric motor can be used The number of 8 is reduced.

此外，由前述工件導引滾筒4、5、6、7、前述傳遞機構9、前述電動馬達8及控制器單元構成導引滾筒裝置，尤其由上游側工件導引滾筒4、5、傳遞機構9、前述電動馬達8及控制器單元構成上游側導引滾筒裝置20，由下游側工件導引滾筒6、7、傳遞機構9、前述電動馬達8及控制器單元構成下游側導引滾筒裝置30。又，上游側工件導引滾筒4、5之間的間隔D及下游側工件導引滾筒6、7之間的間隔D，形成為較工件10之厚度W稍大(D＞W)。前述工件導引滾筒4、5或工件導引滾筒6、7與工件10之間的間隙40，於該實施例較佳為0.4~1.0mm之範圍內，尤其是0.5mm更佳。In addition, the aforementioned workpiece guide rollers 4, 5, 6, 7, the aforementioned transmission mechanism 9, the aforementioned electric motor 8 and the controller unit constitute a guide roller device, especially the upstream side workpiece guide rollers 4, 5, and the transmission mechanism 9. The electric motor 8 and the controller unit constitute the upstream guide roller device 20, and the downstream workpiece guide rollers 6, 7, the transmission mechanism 9, the electric motor 8 and the controller unit constitute the downstream guide roller device 30. In addition, the interval D between the upstream work guide rollers 4 and 5 and the interval D between the downstream work guide rollers 6 and 7 are formed to be slightly larger than the thickness W of the work 10 (D>W). The gap 40 between the aforementioned workpiece guiding rollers 4, 5 or the workpiece guiding rollers 6, 7 and the workpiece 10 is preferably in the range of 0.4 to 1.0 mm in this embodiment, and more preferably 0.5 mm.

藉由以上之構成，根據本發明，於前述上游側導引滾筒裝置20中，如圖4所示，於通過工件送入槽縫部2之工件10，浸漬槽1內之鍍覆液或洗滌液等之液體漏出時產生之施力施加於與搬送方向反方向，進而於上游側工件導引滾筒4、5與工件10之間的間隙40亦同樣地藉由漏出之液體而往與工件10之搬送方向反方向賦予力。然而，上游側導引滾筒4、5之工件10側之周面以與前述搬送速度Ts一致之周速度往搬送方向移動之方式以既定之旋轉速度旋轉，因此工件10儘管漏出之液體所產生之施力存在但亦能維持所期望之搬送速度Ts。With the above configuration, according to the present invention, in the aforementioned upstream guide roller device 20, as shown in FIG. 4, the workpiece 10 is fed into the slot 2 through the workpiece, and the plating liquid or washing liquid in the immersion tank 1 The force generated when the other liquid leaks is applied to the direction opposite to the conveying direction, and the gap 40 between the upstream workpiece guide rollers 4, 5 and the workpiece 10 is similarly transferred to the workpiece 10 by the leaked liquid Force is applied in the opposite direction of the conveying direction. However, the peripheral surface of the upstream guide rollers 4, 5 on the workpiece 10 side rotates at a predetermined rotation speed at a peripheral speed consistent with the aforementioned conveying speed Ts in the conveying direction. Therefore, the workpiece 10 is rotated at a predetermined rotation speed despite the leakage of liquid. The force exists but the desired conveying speed Ts can be maintained.

又，藉由使工件10之搬送速度Ts與上游側工件導引滾筒4、5之外周之周速度一致，即使於工件10例如因振動而與上游側工件導引滾筒4、5之任一者或雙方接觸之情形，亦具有防止對工件10產生損傷的效果，並且可抑制來自工件送入槽縫部2之液漏量。In addition, by making the conveying speed Ts of the workpiece 10 coincide with the peripheral speed of the upstream side workpiece guide rollers 4, 5, even if the workpiece 10 is vibrated with either one of the upstream side workpiece guide rollers 4, 5, for example Or when both sides are in contact, it also has the effect of preventing damage to the workpiece 10, and can suppress the amount of liquid leakage from the workpiece being fed into the slot portion 2.

進而，於下游側導引滾筒裝置30中，如圖5所示，於通過工件送出槽縫部3之工件10，浸漬槽1內之鍍覆液或洗滌液等之液體漏出時產生之施力往搬送方向施加，進而於下游側工件導引滾筒6、7與工件10之間的間隙40亦同樣地藉由漏出之液體而往工件10之搬送方向施力。如上所述，於下游側導引滾筒裝置30，對工件10藉由漏出之液體往使搬送速度Ts上升之方向施加力，但下游側工件導引滾筒6、7，以對應工件10之搬送速度Ts之既定之旋轉速度旋轉，因此將自工件送出槽縫部3漏出之液體限制在工件送出槽縫部3與下游側工件導引滾筒6、7之間的空間，故而能抑制工件10之搬送速度Ts之上升。Furthermore, in the downstream guide roller device 30, as shown in FIG. 5, the force generated when the workpiece 10 passed through the workpiece out of the slot 3, and the plating solution or washing liquid in the immersion tank 1 leaks out. In the conveying direction, the gap 40 between the downstream workpiece guide rollers 6 and 7 and the workpiece 10 is similarly urged in the conveying direction of the workpiece 10 by the leaked liquid. As described above, the downstream guide roller device 30 applies force to the workpiece 10 in a direction that increases the conveying speed Ts by the leaked liquid, but the downstream workpiece guide rollers 6, 7 correspond to the conveying speed of the workpiece 10 Ts rotates at a predetermined rotation speed, so the liquid leaking from the workpiece delivery slot 3 is restricted to the space between the workpiece delivery slot 3 and the downstream workpiece guide rollers 6, 7, so that the transfer speed Ts of the workpiece 10 can be suppressed The rise.

又，藉由使工件10之搬送速度Ts與下游側工件導引滾筒6、7之外周之周速度一致，即使於工件10例如因振動而與下游側工件導引滾筒6、7之任一者或雙方接觸之情形時，亦具有防止對工件10產生損傷的效果，並且也可抑制來自工件送出槽縫部3之液漏量。In addition, by making the conveying speed Ts of the workpiece 10 coincide with the peripheral speed of the downstream side workpiece guide rollers 6, 7 even if the workpiece 10 is vibrated with any one of the downstream side workpiece guide rollers 6, 7 Or when both sides are in contact, it also has the effect of preventing damage to the workpiece 10, and can also suppress the amount of liquid leakage from the slot 3 of the workpiece.
