Description
本發明係關於一種用於切割織物之方法及裝置。裝置具有用於偵測缺陷之一聯機系統。織物可為由單軸拉伸聚合物縱切膜帶(具體而言聚烯烴縱切膜帶，較佳地聚丙烯縱切膜帶)製成之一網或塑膠編織織物。具體而言，設備及方法與識別可具有諸如正方形或管狀之不同形狀之散裝儲存袋之大型或長織物之有缺陷部分及產生剔除/彈出通知相關。 The present invention relates to a method and apparatus for cutting fabrics. The device has an online system for detecting defects. The fabric may be a mesh or plastic woven fabric made from a uniaxially stretched polymer slit film tape, in particular a polyolefin slit film tape, preferably a polypropylene slit film tape. In particular, the apparatus and method are related to identifying defective portions of large or long fabrics, which may have different shapes of bulk storage bags, such as square or tubular, and generating reject/eject notifications.
本發明係關於一種用於切割織物之方法及裝置。設備具有用於偵測缺陷之一聯機系統。織物可為由單軸拉伸聚合物縱切膜帶(具體而言聚烯烴縱切膜帶，較佳地聚丙烯縱切膜帶)製成之一網或塑膠編織織物，其可視情況在一或兩側上塗覆有一熱塑性材料。監測一典型塑膠編織織物之有缺陷區段特有之不規則性係重要的。缺陷可包含編織缺陷、黏在一起之織物端或其他類似缺陷。一些缺陷可為表面性的，然而，一些其他缺陷會損及織物之完整性及強度或影響其諸如防漏之其他期望性質以最終使其不適合於所設計之用途。有缺陷織物之下游處理導致需剔除之故障袋。更糟糕的是，若未剔除此等有缺陷/故障袋，則其會充滿材料以不僅導致材料溢出及損耗且亦影響所儲存之產品或材料之品質。 The present invention relates to a method and apparatus for cutting fabrics. The equipment has an on-line system for detecting defects. The fabric can be a mesh or plastic woven fabric made of uniaxially stretched polymer slit film tapes (specifically polyolefin slit film tapes, preferably polypropylene slit film tapes), which can be optionally a Or coated with a thermoplastic material on both sides. It is important to monitor irregularities specific to defective sections of a typical plastic woven fabric. Defects may include weaving defects, fabric ends stuck together, or other similar defects. Some defects may be superficial, however, some other defects can compromise the integrity and strength of the fabric or affect its other desirable properties, such as leak resistance, ultimately rendering it unsuitable for its intended use. Downstream processing of defective fabrics results in defective bags that need to be rejected. Worse yet, if these defective/faulty bags are not removed, they can fill up with material not only causing material spillage and wastage, but also affecting the quality of the product or material stored.
先前技術中之諸多解決方案可用於偵測此等織物缺陷。根據美國專利申請案US20120133763，提供一種用於拍攝塑膠編織織物之影像之檢查攝影機及一分析單元，其基於由檢查攝影機拍攝之影像來偵測塑膠編織織物之編織圖案之不規則性且其在偵測指示塑膠編織織物之一有缺陷區段之編織圖案之不規則性時觸發一錯誤信號，其致動(例如)一閃光燈或一喇叭或其可饋送至一較高階機器控制器。進一步提供用於監測一塑膠編織織物之缺陷之一檢查系統及分別用於標記或監測一塑膠編織織物之缺陷之一方法之變體。然而，在一高速處理單元上標記織物之有缺陷區域係一笨拙且複雜操作。 Numerous solutions in the prior art are available for detecting such fabric defects. According to the US patent application US20120133763, there is provided an inspection camera for taking an image of a plastic woven fabric and an analysis unit, which detects the irregularity of the weaving pattern of the plastic woven fabric based on the image captured by the inspection camera and which is detected Detecting irregularities in the weave pattern indicative of a defective section of the plastic woven fabric triggers an error signal that activates, for example, a flashing light or a horn or it can be fed to a higher order machine controller. Variations of an inspection system for monitoring a plastic woven fabric for defects and a method for marking or monitoring a plastic woven fabric for defects, respectively, are further provided. However, marking defective areas of fabric on a high-speed processing unit is an awkward and complicated operation.
現今，諸多粉狀或可散裝或其他類似類型之消費品在由厚塑膠編織織物製成之大散裝袋中灌裝、儲存及運送且可具有諸如正方形或管狀之不同形狀。取決於所容納之產品，大散裝袋裝載容量通常係自300kg至2500kg，其中更大單元容納更多。所使用之由塑膠編織織物製成之袋需要滿足各自最終使用用途之品質要求。 Today, many powdered or bulkable or other similar types of consumer products are filled, stored and shipped in large bulk bags made of thick plastic woven fabric and can have different shapes such as square or tubular. Large bulk bag loading capacities typically range from 300kg to 2500kg depending on the product contained, with larger units holding more. The bags made of plastic woven fabric used need to meet the quality requirements of their respective end-use applications.
散裝袋一般快速用於遞送幾乎任何種類之散裝材料，且近年來散裝袋之大小已增大，尤其在相對較輕材料之情況中。 Bulk bags are generally rapidly used to deliver almost any kind of bulk material, and the size of bulk bags has increased in recent years, especially in the case of relatively light materials.
用於包裝諸如(例如)粉末/化學品之特定貨品之散裝塑膠袋必須足夠堅固且塵密以分別在灌裝、儲存及運送程序期間防止污染或粒子離開且亦因此促成保護環境。此外，用於包裝自由流動化學品之塑膠袋必須另外滿足職業安全方面之嚴格要求及關於所用材料對天氣影響之抵抗性之要求。 The bulk plastic bags used to package certain goods such as, for example, powders/chemicals must be strong and dust tight enough to prevent contamination or particles from leaving during filling, storage and shipping procedures, respectively, and thus contribute to protecting the environment. In addition, the plastic bags used for packaging free-flowing chemicals must additionally meet stringent requirements in terms of occupational safety and requirements regarding the resistance of the materials used to the influence of weather.
由塑膠材料製成之散裝包裝袋之生產商及貿易商分別越來越面臨以下問題：自動化灌裝廠之操作者在進貨檢查過程中隨機偵測一有 缺陷袋，使得成百數千個塑膠袋之一完整托板或填料將被回收利用且將必須由供應商取回。由其引起之經濟損失係巨大的。 Manufacturers and traders of bulk bags made of plastic materials are increasingly faced with the following problem: Operators of automated bottling plants randomly detect a Defective bags, such that one of the hundreds of thousands of plastic bags complete pallets or fills will be recycled and will have to be retrieved by the supplier. The economic loss caused by it is huge.
個別散裝袋生產商用於在一塑膠編織紡織品之早期生產期間偵測材料中之缺陷且藉由彩色標記來手動標記此等缺陷之第一種方法至今尚未完全開發。 The first method used by individual bulk bag manufacturers to detect defects in material during early production of a plastic woven textile and to manually mark these defects by color marking has not yet been fully developed.
由於將達成高達100m/min之塑膠編織織物之網速率的快速運行處理機器，藉由操作人員之關於缺陷之一完整及純光學檢查幾乎不可能。例如一平坦材料網(其在袋生產之後續程序步驟中分別形成或封閉成一織物管)處之一缺陷之一彩色標記可因此稍後位於此織物管之內部上且因此將不在一下游光學品質控制中被偵測到。此外，取決於客戶之要求，特定大小及以下之缺陷係可接受的，因此，需要區分需要消除之缺陷之大小。 Due to the fast running processing machines that will achieve web speeds of up to 100 m/min of plastic woven fabrics, a complete and purely optical inspection of defects by an operator is almost impossible. For example a coloured marking of a defect at a flat web of material (which is formed or closed into a fabric tube, respectively, in subsequent process steps of bag production) may therefore be located later on the interior of this fabric tube and thus will not be of a downstream optical quality control detected. In addition, depending on the customer's requirements, defects of a certain size and below are acceptable, therefore, it is necessary to distinguish the size of the defects that need to be eliminated.
沿塑膠編織織物之若干米之一區段發生之大型或長缺陷比小型缺陷更易於由操作人員偵測到。 Large or long defects that occur along a section of several meters of plastic woven fabric are easier to detect by operators than small defects.
一種用於偵測一塑膠編織織物之一有缺陷區段之可靠監測系統，其對缺陷偵測之敏感度可根據客戶之要求來調整，其標記所有發生缺陷且亦偵測塑膠編織織物之此等以下一或若干個後續程序步驟，且僅藉由切割器來切割該有缺陷織物，其繼而最小化有缺陷織物之廢料收集且繼而節省迄今未知之織物長度。 A reliable monitoring system for detecting a defective section of a plastic woven fabric, its sensitivity to defect detection can be adjusted according to customer requirements, it marks all occurrences of defects and also detects this of the plastic woven fabric Wait for one or several subsequent procedural steps, and cut the defective fabric only by the cutter, which in turn minimizes waste collection of the defective fabric and thus saves hitherto unknown fabric lengths.
因此，需要用於針對大散裝袋之大型或長織物來偵測上述缺陷且在其處切割之方法及裝置。 Accordingly, there is a need for a method and apparatus for detecting and cutting the above-mentioned defects for large or long fabrics of large bulk bags.
本發明之主要目的係提供一種用於切割織物且同時偵測一 塑膠編織織物中之缺陷之裝置。 The main object of the present invention is to provide a method for cutting fabrics while simultaneously detecting a Device for defects in plastic woven fabrics.
本發明之另一目的係提供一種用於使用用於偵測缺陷之此一裝置來監測缺陷之缺陷偵測系統。 Another object of the present invention is to provide a defect detection system for monitoring defects using such a device for detecting defects.
本發明之又一目的係監測大型或長織物中之缺陷且最小化切割之後的損耗。 Yet another object of the present invention is to monitor defects in large or long fabrics and minimize wastage after cutting.
根據本發明，藉由提供其中偵測織物之有缺陷區域之一切割裝置來達成此等目的。註解有缺陷區域之座標。透過織物切割器來監測沿生產線之織物之有缺陷區域之進展。識別含有缺陷之織物之切割片。根據客戶觀察及要求來手動切割含有缺陷之切割片以藉此最小化切割之後的損耗且分離所彈出之正常切割片。 According to the present invention, these objects are achieved by providing a cutting device in which defective areas of the fabric are detected.

The location of the defect as a single or isolated defect or as a defect cluster can vary. The aim of the present invention is to maximize the defect-free cut length of the web material (3) and minimize the length of the defective portion of the web material (3). Depends on individual customer requirements and use without defects The end use of the mesh material, the operator can set the desired length (L) of one of the individual defect-free mesh pieces (3a) of the mesh material (3). A semi-automated device (15) allows the operator to identify defects (8) or clusters of defects and use a cutter (5) to cut out the portion containing it. The semi-automatic device ( 15 ) also allows the defect-free portion of the mesh material ( 3 ) to be cut into pieces of the desired length L.
控制單元(9)在偵測到一缺陷(8)或缺陷叢集之後使網材料(3)恰好在切割器(5)前面依長度(L1)停止前進，長度(L1)可根據個別客戶要求來改變或其可依最小距離預設以節省網材料(3)長度，使得半自動化裝置(15)之操作者可檢查含有缺陷(8)之網材料(3)之區域。 After detecting a defect (8) or defect cluster, the control unit (9) stops the web material (3) just in front of the cutter (5) by the length (L1), which can be adjusted according to individual customer requirements. It can be changed or preset at a minimum distance to save the length of the web material (3) so that the operator of the semi-automatic device (15) can inspect the area of the web material (3) containing defects (8).
在一實施例中，掃描器及缺陷偵測器(4)經放置使得被掃描之網材料(3)係水平的，使得藉由操作者之檢查活動變得方便。在使網材料(3)停止前進之後，操作者檢查網材料(3)且判定切口之位置。如圖3中由虛線所展示，其可視情況判定定界切口(16)之位置以包含單一缺陷(8)或缺陷叢集，使得識別網材料(3)之一有缺陷部分用於切割。接著，操作者使網材料開始前進，使得切割器(5)在由操作者識別之位置處在網材料(3)中產生定界切口(16)以消除一有有缺陷片(3b)。定界切口係界定有缺陷片(3b)之一對切口。 In one embodiment, the scanner and defect detector (4) are positioned such that the web material (3) being scanned is horizontal, facilitating inspection activities by the operator. After stopping the advancement of the mesh material (3), the operator inspects the mesh material (3) and determines the position of the cut. As shown by the dashed line in Figure 3, it is optional to decide where to delimit the cut (16) to contain a single defect (8) or a cluster of defects so that a defective portion of the web material (3) is identified for cutting. Next, the operator advances the web material so that the cutter (5) creates a delimiting cut (16) in the web material (3) at a location identified by the operator to eliminate a defective piece (3b). The delimiting cuts are a pair of cuts that define the defective sheet (3b).
在產生定界切口(16)之後，操作者使用控制單元(9)來重啟半自動化裝置(15)以使網材料(3)前進。連續掃描網材料，且若無缺陷網材料(3)之任何長度超過預定長度L，則前進網材料在切割器處暫停以在網材料(3)中產生橫向切口，使得產生無缺陷網材料之個別無缺陷網片(3a)。控制單元(9)確保前進網材料(3)在各此切割之前暫停且在切割之後再次開始前進。在偵測到下一缺陷(8)之後，重複識別待切割之網材料(3)之有缺陷部分之程序。 After making the delimiting cut (16), the operator uses the control unit (9) to restart the semi-automatic device (15) to advance the web material (3). The web material is continuously scanned, and if any length of the defect-free web material (3) exceeds a predetermined length L, the advancing web material is paused at the cutter to create transverse cuts in the web material (3) such that a defect-free web material is produced. Individual defect-free mesh (3a). The control unit (9) ensures that the advancing web material (3) pauses before each such cut and starts to advance again after the cut. After the detection of the next defect (8), the procedure of identifying the defective part of the web material (3) to be cut is repeated.
