[先前技術文獻]
[專利文獻]
As a device for conveying linear objects such as conveyor ropes and steel wires, or planar objects such as paper or cloth, devices that detect the tension of the conveyed objects are widely known. For example,
[專利文獻1] 日本特開2003-176080號公報[Patent Document 1] Japanese Patent Application Publication No. 2003-176080
[發明所欲解決之問題][Problem to be solved by the invention]
專利文獻1中的張力檢測器嚴格來說,並不直接檢測被輸送物的張力,而是檢測對被輸送物施加張力之張力調節輥的位置。因此,在張力調節輥的位置與被輸送物的張力的相關性不完全之情況下,導致在被輸送物的張力的控制中產生誤差。Strictly speaking, the tension detector in
本發明係鑑於該種狀況而完成者,其目的在於提供一種能夠高精度地控制被輸送物的張力之輸送控制裝置等。 [解決問題之技術手段] The present invention was made in view of this situation, and an object thereof is to provide a conveyance control device and the like that can control the tension of an object to be conveyed with high precision. [Technical means to solve problems]
為了解決上述問題,本發明的一態樣的輸送控制裝置具備:張力檢測部,檢測藉由張力調節輥施加了張力之被輸送物的張力;張力指令生成部,生成被輸送物的張力指令;及推力校正部,依據檢測出之張力與張力指令之差,校正與被輸送物的張力相反方向地施加於張力調節輥之推力。In order to solve the above problem, a conveyance control device according to one aspect of the present invention includes: a tension detection unit that detects the tension of an object to be conveyed to which tension is applied by a tension adjustment roller; a tension command generation unit that generates a tension command for the object to be conveyed; And the thrust correction part corrects the thrust applied to the tension adjustment roller in the opposite direction to the tension of the object to be conveyed based on the difference between the detected tension and the tension command.
依該態樣,直接檢測被輸送物的張力,依據與張力指令之差來校正施加於張力調節輥之推力(與被輸送物的張力平衡),藉此能夠高精度地控制被輸送物的張力。According to this aspect, the tension of the conveyed object is directly detected, and the thrust applied to the tension adjustment roller is corrected based on the difference with the tension command (balanced with the tension of the conveyed object), thereby enabling high-precision control of the tension of the conveyed object. .

The method includes: a tension detection step, which detects the tension of the conveyed object with tension applied by the tension adjustment roller; a tension command generation step, which generates a tension command of the conveyed object; and a thrust correction step, based on the detected tension and the tension command. The difference corrects the thrust applied to the tension adjustment roller in the opposite direction to the tension of the conveyed object.

以下,一邊參照圖式,一邊對用於實施本發明之方式(以下亦稱為實施方式)進行詳細說明。說明及/或圖式中,對相同或等同的構成要素、構件、處理等標註相同的符號並省略重複之說明。關於圖示之各部的縮尺或形狀,為了說明的簡易化,適當地進行設定,除非另有特別說明,否則不作限定性解釋。實施方式係例示的,對本發明的範圍並不作任何限定。實施方式中記載之所有特徵和該等的組合並不一定係本發明的本質特徵。Hereinafter, modes for implementing the present invention (hereinafter also referred to as embodiments) will be described in detail with reference to the drawings. In the description and/or drawings, the same or equivalent components, members, processes, etc. are denoted by the same symbols, and repeated descriptions are omitted. The scale and shape of each part shown in the drawings are set appropriately for the sake of simplicity of explanation, and are not to be interpreted in a restrictive manner unless otherwise specified. The embodiments are illustrative and do not limit the scope of the present invention in any way. All features described in the embodiments and their combinations are not necessarily essential features of the present invention.
圖1示意地表示本發明的實施方式之輸送控制裝置1的構成。輸送控制裝置1係控制輸送被輸送物3之輸送裝置2的輸送動作之裝置。作為被輸送物3,例示有繩或鋼絲等線狀的被輸送物或者紙、布、膜、箔、橡膠等面狀的被輸送物。本實施方式中,對將面狀的基材作為被輸送物3向輸送方向(圖1中的左右方向)輸送之輥對輥(Roll-to-Roll)方式的輸送裝置2進行說明。輸送裝置2可以係對被輸送之被輸送物實施任意處理之裝置、例如對被輸送物實施塗布之塗布機或塗布裝置、對被輸送物實施印刷之印刷機、對被輸送物施加張力而延伸之延伸裝置等的一部分。FIG. 1 schematically shows the structure of the
輸送裝置2具備驅動輥231、驅動輥251、張力調節器24及張力檢測器26。在由後述之驅動部161旋轉驅動之驅動輥231中,可以並列設置有在與該驅動輥231之間夾持被輸送物3並與該驅動輥231連動而旋轉之從動輥232。在由後述之驅動部16旋轉驅動之驅動輥251中,可以並列設置有在與該驅動輥251之間夾持被輸送物3並與該驅動輥251連動而旋轉之從動輥252。另外,在驅動輥231及/或驅動輥251由吸輥等構成之情況下,無需設置從動輥232及/或從動輥252。The
驅動輥231/251及從動輥232/252係作為輸送被輸送物3之輸送部的一態樣的輸送輥,能夠繞與輸送方向(圖1中的左右方向)正交之方向(與圖1的紙面垂直的方向)的旋轉軸旋轉。驅動輥231/251根據由速度控制部151/15生成之旋轉速度指令藉由馬達等驅動部161/16旋轉驅動。在圖1中的被輸送物3的輸送方向為向右之情況下,驅動輥231/251藉由驅動部161/16向順時針方向旋轉驅動,從動輥232/252與驅動輥231/251連動而向逆時針方向旋轉。The
張力調節器24設置在驅動輥231與驅動輥251之間。The
張力調節器24對被輸送物3施加輸送方向上的張力。張力調節器24具備:一對輥241、242,設置在被輸送物3的輸送路徑(圖1中被輸送物3延伸之左右方向的路徑)上:及張力調節輥243,在該一對輥241、242之間設置在從被輸送物3的輸送路徑脫離之位置。另外,張力調節輥亦稱為張力調節滾筒。The tension adjuster 24 applies tension in the conveying direction to the conveyed
張力調節輥243在遠離被輸送物3的輸送路徑之方向(圖1中的上下方向)上以能夠在上端243A與下端243B之間移動的方式設置。作為推力施加部的氣缸244生成對張力調節輥243向遠離被輸送物3的輸送路徑之方向(圖1中的下方)蓄勢或加壓之推力。該推力基於經由活塞桿或連桿連接於張力調節輥243之氣缸244的氣壓。氣缸244的氣壓由後述之推力校正部19生成,前述推力校正部19由藉由電力控制氣壓之電動氣動調整器等構成。以往的電動氣動調整器中,一般而言施加有恆定的電壓,氣缸的氣壓亦即張力調節輥的推力被控制為恆定,但本實施方式中,自適應地控制氣缸244的氣壓亦即張力調節輥243的推力。另外,亦可以設置推力施加部(例如,依據電力對張力調節滾筒243施加推力之線性馬達等)來代替氣缸244,前述推力施加部依據其他原理對張力調節滾筒243施加推力。The
藉由來自氣缸244的推力向下方蓄勢或加壓之張力調節輥243藉由向遠離輸送路徑之方向拉伸被輸送物3而對該被輸送物3施加張力。此時,張力調節輥243在從氣缸244受到之向下的推力與從被輸送物3受到之向上的張力平衡之位置靜止。如前所述,一般而言,由於張力調節輥243從氣缸244受到之向下的推力被維持或控制為大致恆定,因此張力調節輥243的上下方向的位置表示被輸送物3的張力。The
推力的方向(圖1中的上下方向)上的張力調節輥243的位置藉由位置檢測部245或位置感測器作為電訊號而被檢測,並提供給輸送控制裝置1的減法器14。除此以外,減法器14中輸入由輸送控制裝置1的位置指令生成部13生成之推力的方向上的張力調節輥243的位置指令。輸送控制裝置1的速度控制部15生成用於減小由減法器14提供之張力調節輥243的位置或被輸送物3的張力的偏差之速度指令。該速度指令係針對被輸送物3的輸送速度之指令,具體而言,係針對以下說明之驅動輥251的旋轉速度之指令。The position of the
輸送控制裝置1的驅動部16及/或161根據由速度控制部15及/或151提供之速度指令,旋轉驅動並列設置於張力調節器24的緊後方及/或跟前之驅動輥251及/或驅動輥231。以下,對並列設置於張力調節器24的緊後方之驅動輥251的控制進行詳述,但該等內容亦能夠適用於並列設置於張力調節器24的跟前之驅動輥231的控制。又,圖1中,省略了與並列設置於張力調節器24的跟前之驅動輥231有關之構成(例如位置指令生成部13和減法器14等)。驅動輥251係能夠繞與被輸送物3的輸送方向正交之旋轉軸旋轉之輸送輥。若驅動輥251向圖1中的順時針方向旋轉驅動,則從動輥252與驅動輥251連動而向逆時針方向旋轉。驅動輥251的旋轉速度根據位置及/或張力的偏差而自適應地進行控制。如此,驅動輥251及從動輥252一邊輸送夾在其之間之被輸送物3,一邊控制由位置指令生成部13生成之張力調節輥243的位置。The
如上所述,張力調節器24並不是僅藉由施加恆定推力(僅藉由推力與基材張力的平衡進行張力控制)而直接檢測實際的張力來進行控制,因此張力精度取決於對電動氣動轉換器的電壓指令或氣缸的氣壓指令,導致在被輸送物3的張力的控制中產生誤差。如以下所說明,依本實施方式之輸送控制裝置1,除了基於張力調節器24之「粗」張力控制以外及/或代替基於張力調節器24之「粗」張力控制,實現「細」張力控制,藉此與以往相比能夠高精度地控制被輸送物3的張力。為了進行細張力控制,在輸送裝置2中,直接檢測藉由張力調節輥243施加了張力之被輸送物3的張力之張力檢測器26設置在作為張力控制區間的驅動輥231與251之間。可以設置在張力調節器24的前級/後級。As mentioned above, the
輸送控制裝置1中,作為用於實現粗張力控制之功能方塊,具備前述位置指令生成部13、減法器14、速度控制部15及驅動部16,作為用於實現細張力控制之功能方塊,具備張力指令生成部17、減法器18及推力校正部19。該等功能方塊藉由電腦的中央運算處理裝置、記憶體、輸入裝置、輸出裝置、連接於電腦之周邊機器等硬體資源和使用該等而執行之軟體的協作來實現。無論電腦的種類或設置場所如何,上述各功能方塊可以由單一電腦的硬體資源實現,亦可以組合分散在複數個電腦之硬體資源來實現。The
張力指令生成部17生成被輸送物3的張力指令。作為張力檢測部發揮功能之減法器18運算由張力檢測器26直接檢測出之被輸送物3的張力與由張力指令生成部17生成之張力指令之差。推力校正部19依據由減法器18運算出之實際的張力與張力指令之差,校正向與被輸送物3的張力相反的方向(圖1中的向下)施加於張力調節輥243之推力。具體而言,推力校正部19例如由電動氣動調整器構成,對氣缸244施加用於減小實際的張力與張力指令的張力偏差之電壓。並且,氣缸244自適應地生成直接與所期望的張力平衡之向下的推力或氣壓,藉此直接最小化張力偏差。如此,依本實施方式,與以往相比能夠高精度地控制被輸送物3的張力。The tension
以上,依據實施方式對本發明進行了說明。作為例示的實施方式中的各構成要素或各處理的組合中能夠有各種變形例,且該種變形例包含在本發明的範圍內,這對於本領域具有通常知識者來說係顯而易見的。The present invention has been described above based on the embodiments. It is obvious to a person with ordinary knowledge in the art that various modifications can be made to the combination of each component or each process in the illustrated embodiments, and that such modifications are included in the scope of the present invention.
另外,實施方式中所說明之各裝置或各方法的構成、作用、功能能夠藉由硬體資源或軟體資源或者藉由硬體資源和軟體資源的協作來實現。作為硬體資源,例如,能夠利用處理器、ROM、RAM、各種積體電路。作為軟體資源,例如,能夠利用操作系統、應用程式等程式。 本申請案係主張基於2022年3月24日申請之日本專利申請第2022-047933號的優先權。該日本申請案的全部內容係藉由參閱而援用於本說明書中。 In addition, the configuration, action, and function of each device or each method described in the embodiments can be realized by hardware resources or software resources, or by cooperation of hardware resources and software resources.
