Description
本發明有關一用於紡紗機之牽伸裝置的頂部皮圈架，其具有藉由彈簧彈力所加載之至少一導條皮圈，並張緊一頂部皮圈及在一撓曲邊緣使該頂部皮圈撓曲，該導條皮圈被固持在該頂部皮圈架之十字頭上。The present invention relates to a top apron frame for a drafting device for a spinning machine having at least one guide apron loaded by a spring force and tensioning a top apron and at a flexing edge The top apron flexes and the guide apron is held on the crosshead of the top apron frame.
根據本申請案之申請專利範圍第1項的前言之頂部皮圈架係由德國新型案第DE 92 14 598 U1號所得知，其具有張緊一頂部皮圈及使一頂部皮圈撓曲之導條皮圈，且被固持在該頂部皮圈架之十字頭上。該導條皮圈被以一彈簧彈力所加載，以在一被界定之張力下固持該頂部皮圈。為導引該導條皮圈，該頂部皮圈架係設有一模鑄型軸頭，於每一案例中，該導條皮圈被導引於模製在該十字頭上之對應通道中。根據德國新型案第DE 92 14 598 U1號，該等軸頭及該等通道被配置在該皮圈架上或該十字頭上之頂部皮圈的運行路徑寬度內。該十字頭中之通道的深度在此被限制於該十字頭在此位置之寬度。The top apron frame according to the preamble of claim 1 of the present application is known from the German patent application No. DE 92 14 598 U1, which has a top apron and a top apron The guide apron is held on the crosshead of the top apron frame. The guide apron is loaded with a spring force to hold the top apron under a defined tension. To guide the guide apron, the top apron frame is provided with a molded shaft head, and in each case, the guide apron is guided into a corresponding passage molded on the crosshead. According to German Patent No. DE 92 14 598 U1, the isometric heads and the passages are arranged on the apron frame or within the width of the running path of the top apron on the crosshead. The depth of the channel in the crosshead is here limited to the width of the crosshead at this location.
其已經證實為不利的是在由該先前技藝所習知之頂部皮圈架中，該撓曲邊緣相對於該導條皮圈的水平面之上下運動的尺寸係大於被用在導引的軸頭與通道間之有關製造的游隙。其成因係該導條皮圈相對該頂部皮圈架的十字頭上之通道的突出配置。當藉由該導條皮圈所張緊之頂部皮圈被造成運動時、及反之當該頂部皮圈係停止時，總是發生該撓曲邊緣的高度中之變化。發生在該頂部皮圈中之張力被不同地引導，而如該操作狀態的一函數。這導致以下之事實，即在該頂部皮圈之操作期間，該導條皮圈之撓曲邊緣被向上拉，而當該頂部皮圈係停頓時，該撓曲邊緣被往下撓曲。然而，與該底部皮圈橋接件或該底部皮圈作比較，該導條皮圈之下緣的撓曲之高度係一製程參數，其持續地影響該隨後的紡絲過程之結果，故該撓曲之高度的知識係很重要的。該撓曲邊緣應被定位，使得該頂部皮圈及該底部皮圈彼此平行延伸，而相對於其高度變化，該定位於操作期間僅只可被不輕易地決定或全然不能被決定。It has proven to be disadvantageous that in the top apron frame known from the prior art, the size of the flexing edge to move up and down relative to the horizontal plane of the bead of the guide bar is greater than that used to guide the axe. The clearance between the channels for manufacturing. The cause is the protruding arrangement of the guide apron relative to the passage on the crosshead of the top apron frame. A change in the height of the flexing edge always occurs when the top apron tensioned by the guide apron is caused to move, and vice versa when the top apron is stopped. The tension occurring in the top apron is directed differently, as a function of the operational state. This results in the fact that during the operation of the top apron, the flexing edge of the guide apron is pulled up, and when the top apron is paused, the flexing edge is deflected downward. However, compared to the bottom apron bridge or the bottom apron, the height of the deflection of the lower edge of the bead of the guide strip is a process parameter that continuously affects the outcome of the subsequent spinning process, so The level of knowledge of flexing is important. The flexing edge should be positioned such that the top apron and the bottom apron extend parallel to one another, and relative to its height variation, the positioning can only be determined not easily or completely undetermined during operation.
本發明之目的係因此提供一頂部皮圈架，其係藉由該撓曲邊緣之撓曲的一小變動所區別，尤其當該頂部皮圈之操作狀態中有一變化時。It is therefore an object of the present invention to provide a top apron frame that is distinguished by a small variation in the deflection of the flexing edge, particularly when there is a change in the operational state of the top apron.
這是根據本發明藉由申請專利範圍第1項之特徵特色所達成。This is achieved according to the invention by the features of the first item of the patent application.
本發明之有利發展係該等申請專利範圍附屬項之標的。Advantageous developments of the invention are the subject matter of the dependent claims.
根據申請專利範圍第1項，其被提出彼此對應及被使用於導引該導條皮圈的導引元件之至少一對，係在該頂部皮圈的運行路徑寬度之外配置於該十字頭上及該導條皮圈上。與根據該先前技藝之配置作比較，此配置之實質優點係被使用於導引該導條皮圈之導引元件可被製成為較長的，據此該等導引元件被配置在該運行路徑寬度內側及在該導條皮圈之下方。由於此措施，與由該先前技藝所習知之頂部皮圈架作比較，該導引長度可被顯著地加長，故該撓曲邊緣之上下運動的尺寸係減少至相對於其被使用於導引之導引元件的尺寸所習知之函數相關游隙。由於該操作狀態中之變化的結果，如上面關於該先前技藝所敘述者，該撓曲邊緣之傾斜係藉由此配置實際上完全地被避免。因為該頂部皮圈之操作狀態的變化，藉由減少該撓曲邊緣之撓曲的大小，正面地影響該牽伸製程及該隨後的紡絲過程之結果。According to the first aspect of the patent application, at least one pair of guiding elements that are proposed to correspond to each other and used for guiding the apron of the guide strip are disposed on the crosshead outside the width of the running path of the top apron And the guide strip on the apron. In contrast to the configuration according to the prior art, the substantial advantage of this configuration is that the guiding elements used to guide the guide apron can be made longer, whereby the guiding elements are configured in the operation Inside the path width and below the guide apron. Due to this measure, the lead length can be significantly lengthened as compared to the top apron frame known from the prior art, so that the size of the upper and lower movement of the flexing edge is reduced to be used relative to it. The function-related clearance of the known dimensions of the guiding element. As a result of the change in the operational state, as described above with respect to this prior art, the tilt of the flexing edge is virtually completely avoided by this configuration. Because of the change in the operational state of the top apron, the result of the drafting process and the subsequent spinning process is positively affected by reducing the amount of deflection of the flexing edge.
用於此目的，該十字頭上之至少一導引元件可被組構成為一導引溝槽，而該導條皮圈上之至少一導引元件可被組構成為一導軌。For this purpose, at least one guiding element on the crosshead can be formed as a guiding groove, and at least one guiding element on the apron of the guiding strip can be formed as a guide rail.
該導引溝槽或該導軌在此可為連續的。The guiding groove or the guide rail can be continuous here.
另一選擇係，被組構成為至少一導引溝槽之導引元件可具有一中斷部。Alternatively, the guiding elements configured as at least one guiding groove may have an interruption.
同樣地，被組構成為至少一導軌之導引元件可具有一中斷部。Likewise, the guiding elements which are formed as at least one guide rail can have an interruption.
選擇該導軌及/或該導引溝槽的水平面中所提供之中斷部的範圍，使得該導引溝槽及導軌之無中斷部份至少局部地重疊。The extent of the interruption provided in the horizontal plane of the guide rail and/or the guide groove is selected such that the uninterrupted portion of the guide groove and the guide rail at least partially overlap.
如此，該至少一導引溝槽上及/或該至少一導軌上之中斷部的配置應該被選擇，使得一被中斷導軌之所有該等部份總是至少與該被中斷導引溝槽之其對應部份局部地嚙合，而與該導條皮圈相對該十字頭之位置無關，以可靠地避免該撓曲邊緣由於該操作狀態中之變化的結果之傾斜。Thus, the configuration of the interrupting portion on the at least one guiding groove and/or the at least one guiding rail should be selected such that all of the portions of the interrupted guiding rail are always at least with the interrupted guiding groove. The corresponding portion is partially engaged regardless of the position of the guide apron relative to the crosshead to reliably avoid tilting of the flexed edge as a result of variations in the operational state.
於一較佳實施例中，該導引溝槽可在其水平面內延伸超出該導條皮圈之縱向範圍，但被可使用之安裝空間所限制。這進一步有利於該撓曲邊緣之上下運動的尺寸之減少的所敘述效應。In a preferred embodiment, the guide groove may extend beyond its longitudinal extent in the horizontal plane of the guide strip, but is limited by the available mounting space. This further facilitates the recited effect of a reduction in the size of the downward movement of the flexing edge.
特別地是，該導引溝槽可延伸直至該導條皮圈之撓曲邊緣。如此，該導條皮圈超出該導引溝槽之突出部份能被減少。如果在遠離該撓曲邊緣之導條皮圈的側面上之導引溝槽突出超過該導條皮圈側面，同理能被達成，以減少該突出部份。In particular, the guiding groove can extend up to the flexing edge of the guide apron. Thus, the protruding portion of the guide apron beyond the guiding groove can be reduced. If the guiding groove on the side of the guide apron remote from the flexing edge protrudes beyond the side of the bead of the guide bar, the same can be achieved to reduce the protruding portion.
於一較佳實施例中，該導條皮圈可被設計在具有一導軌之兩側面上，且該十字頭可被設計成具有對應之導引溝槽。此組構具有該等導條皮圈可為在兩側面上之設計中完全相同的優點，其在較佳地是被設計為一射出成形零件的零組件之生產成本上、及該頂部皮圈架之組裝具有一有利之效果。In a preferred embodiment, the guide apron can be designed on both sides of a guide rail, and the crosshead can be designed to have a corresponding guide groove. The configuration having the guide aprons can be an identical advantage in the design on both sides, preferably in the production cost of a component designed to be a molded part, and the top apron The assembly of the frame has an advantageous effect.
該二導引溝槽之長度較佳地是可為不同的。該十字頭之此組構簡化該頂部皮圈之組裝及拆卸。The length of the two guiding grooves may preferably be different. This configuration of the crosshead simplifies the assembly and disassembly of the top apron.
該二導引溝槽之較短者在此將被配置在該十字頭之外部邊緣上，以便能夠更輕易地施加及移去該頂部皮圈。The shorter of the two guiding grooves will here be arranged on the outer edge of the crosshead so that the top apron can be applied and removed more easily.
本發明將在下面以該等圖面中所顯示之實施例的輔助被更詳細地敘述，其中：The invention will be described in more detail below with the aid of the embodiments shown in the drawings, wherein:
在圖1中之視圖顯示一頂部皮圈架1，其包括一個十字頭2與二個導條皮圈3。該十字頭2被放置在雙頂部滾筒6之軸心5上。該雙頂部滾筒6係以習知之方式被固持在一頂部滾筒承載及加重支臂之導引件上。該等導條皮圈3係與該二可旋轉地安裝式頂部滾筒6有關聯。The view in Figure 1 shows a top apron frame 1 comprising a crosshead 2 and two guide aprons 3. The crosshead 2 is placed on the axis 5 of the double top drum 6. The double top drum 6 is held in a conventional manner on a guide of the top drum carrying and weighting arms. The guide aprons 3 are associated with the two rotatable mounted top rollers 6.
一未示出之頂部皮圈環行該頂部滾筒6及該導條皮圈3。該頂部皮圈在此經由該導條皮圈3被導引及使其在一撓曲邊緣16撓曲。該導條皮圈3之運行路徑寬度3係藉由配置在該導條皮圈3而垂直於該頂部皮圈之運動方向的壁面4所限制，如能被由圖1至3看出者，故該頂部皮圈能防止由該導條皮圈3滑動。為張緊該頂部皮圈，該導條皮圈3被以一彈簧彈力加載，該彈簧彈力係藉由一配置於該十字頭2及該個別導條皮圈3間之彈簧7所產生。如圖3中所顯示，該彈簧7被配置該十字頭2與該導條皮圈3之個別互相咬合圓形通道中，以保護該彈簧7免於纖維飛花。An overhead apron, not shown, loops the top roller 6 and the guide apron 3. The top apron is guided here via the guide apron 3 and deflected at a flexing edge 16 . The running path width 3 of the guide apron 3 is limited by the wall surface 4 disposed in the direction of movement of the top apron 3 in the guide apron 3, as can be seen from Figures 1 to 3, Therefore, the top apron can be prevented from sliding by the guide apron 3. To tension the top apron, the guide apron 3 is loaded with a spring force generated by a spring 7 disposed between the crosshead 2 and the individual guide apron 3. As shown in Fig. 3, the spring 7 is configured to engage the individual of the crosshead 2 and the guide apron 3 in a circular passage to protect the spring 7 from fiber flying.
為導引該導條皮圈3，導引元件在該頂部皮圈的運行路徑寬度之外側被模製在該十字頭2上。於所顯示之實施例中，該等導引元件被組構成如配置在該頂部皮圈之運行路徑寬度外側的導引溝槽11及導軌12。該等導引溝槽11被使用於承納模製在該導條皮圈3上之對應導軌12。再者，在其自由端具有閂扣凸出部14之軸頭13被配置在該運行路徑寬度內側的導條皮圈3上。該等軸頭13嚙合在亦位於該頂部皮圈之運行路徑寬度內側的對應通道15中。該導條皮圈3之閂扣凸出部14於其被組裝在該十字頭2上之位置中嚙合在該等通道15中之壁凹後方。這當該頂部皮圈被移去時，防止該導條皮圈3能夠由該頂部皮圈架1之十字頭2脫離。To guide the guide apron 3, the guiding element is molded on the crosshead 2 on the outer side of the running path width of the top apron. In the embodiment shown, the guiding elements are grouped such that the guiding grooves 11 and the guide rails 12 are disposed outside the width of the running path of the top apron. The guide grooves 11 are used to receive corresponding guide rails 12 molded on the guide bead 3 . Further, the shaft head 13 having the latch projection 14 at its free end is disposed on the guide apron 3 inside the width of the running path. The isometric heads 13 engage in corresponding passages 15 which are also located inside the width of the running path of the top apron. The latching projections 14 of the guide apron 3 engage behind the recesses in the channels 15 in the position in which they are assembled on the crosshead 2. This prevents the guide apron 3 from being disengaged from the crosshead 2 of the top apron frame 1 when the top apron is removed.
如能被由圖2中之視圖看出，該十字頭2在配置該個別導條皮圈3之區域中具有一比該十字頭2之中心區域較小的水平範圍，其被用於緊固在該雙頂部滾筒6之軸心5上。這是由於以下事實，即在傳統頂部皮圈架1中，被用於導引該導條皮圈3之該等軸頭13及該等對應通道15係相對於其長度被限制，因它們被配置在該導條皮圈3或該十字頭2上之頂部皮圈的運行路徑寬度內側。As can be seen from the view in Fig. 2, the crosshead 2 has a smaller horizontal extent than the central region of the crosshead 2 in the region in which the individual guide apron 3 is arranged, which is used for fastening On the axis 5 of the double top drum 6. This is due to the fact that in the conventional top apron frame 1, the equiaxed heads 13 used to guide the guide apron 3 and the corresponding passages 15 are constrained relative to their length since they are The inner apron of the guide apron 3 or the crosshead 2 is disposed inside the width of the running path.
因為根據該等導引溝槽11及在該頂部皮圈之運行路徑寬度外側的該等對應導軌12之本發明的配置，該等導引溝槽11及該等對應導軌12在設計中可為比根據該先前技藝在該頂部皮圈之運行路徑寬度內側的該等通道15及該等軸頭13較長。再者，如可被由圖3看出，該等導軌12之前端延伸進入該導條皮圈3的撓曲邊緣16之正面附近，故該導條皮圈3之突出超過該導軌11係減少。由於這些措施，該導條皮圈3的撓曲邊緣16之可能的上下運動之大小係仍然僅只大約為該等導引元件之就其作用所造成的游隙之量值。當造成該頂部皮圈運動或當該頂部皮圈被停止時，由於該操作狀態中之變化的結果，藉此實際上防止該撓曲邊緣16由於發生張力之傾斜，該等張力係如該操作狀態之函數般被不同地引導。The guide grooves 11 and the corresponding guide rails 12 may be designed in the design according to the arrangement of the guide grooves 11 and the corresponding guide rails 12 outside the width of the running path of the top apron. The channels 15 and the isometric heads 13 are longer than the width of the running path of the top apron according to the prior art. Furthermore, as can be seen from FIG. 3, the front ends of the guide rails 12 extend into the vicinity of the front side of the flexing edge 16 of the guide bead 3, so that the protrusion of the guide apron 3 exceeds the guide rail 11 . Due to these measures, the possible up and down movement of the flexing edge 16 of the guide apron 3 is still only about the magnitude of the play caused by the action of the guiding elements. When the top apron is caused to move or when the top apron is stopped, the deflection of the flexing edge 16 due to the tension is actually prevented as a result of the change in the operational state, such tension The function of the state is guided differently.
該十字頭2之導引溝槽11能如超出該撓曲邊緣16或超出遠離該撓曲邊緣16之側面的可使用安裝空間之函數般被加長。The guiding groove 11 of the crosshead 2 can be lengthened as a function of the available mounting space beyond the flexing edge 16 or beyond the side away from the flexing edge 16.
圖4顯示一頂部皮圈架1'之修改實施例的平面圖，且圖5顯示根據該第二實施例且根據圖4的導條皮圈之平面圖。於此實施例中，在該十字頭2'上之導引溝槽11'與在遠離該導條皮圈3'之撓曲邊緣16的側面上之導軌12'的形式中，該等導引元件被加長，如可由圖4及5中被看出者。該優點係藉由最佳利用該頂部皮圈架1'之可用的後方安裝空間，藉著該等導引元件11'、12'之加長超出該十字頭2'之寬度，當該操作狀態中有一超出該等導引元件11'、12'間之現存游隙的變化時，該導條皮圈3'之翹起傾斜能被減少。Figure 4 shows a plan view of a modified embodiment of a top apron frame 1', and Figure 5 shows a plan view of the guide apron according to the second embodiment and according to Figure 4. In this embodiment, the guiding groove 11' on the crosshead 2' and the guide rail 12' on the side away from the flexing edge 16 of the bead apron 3' are guided. The components are lengthened as can be seen in Figures 4 and 5. This advantage is achieved by optimally utilizing the available rear mounting space of the top apron frame 1' by the lengthening of the guiding elements 11', 12' beyond the width of the crosshead 2', in the operational state When there is a change in the existing play beyond the guiding elements 11', 12', the tilting inclination of the guide apron 3' can be reduced.
再者，圖6顯示一根據第三實施例之導條皮圈3"的立體圖，該導條皮圈3"之導軌12"係至少在一位置藉由壁凹10所中斷。在此該導引溝槽11中之導軌12"所顯示的中斷式組構導致二點鄰接，且係一輕微之修改，然而，其確保與具有根據圖1至5之連續式導軌12及12'的導條皮圈3、3'之變型相同的穩定性。同樣地，該導引溝槽及/或該導軌亦可被設有至少一中斷部或壁凹10。該導引溝槽之中斷部可為一材料之壁凹，其不會阻礙該連續式導軌12、12'之滑動移位性，且亦不會在該被中斷的導引溝槽之水平面中阻礙藉由一壁凹10所中斷之導軌12"的滑動移位性。Furthermore, Figure 6 shows a perspective view of a guide apron 3" according to a third embodiment, the guide rail 12" of the guide apron 3" being interrupted by at least one position by a recess 10. The interrupted configuration shown by the guide rail 12" in the guide groove 11 results in a two-point abutment with a slight modification, however, it ensures a guide strip with the continuous guide rails 12 and 12' according to Figures 1 to 5 The stability of the apron 3, 3' is the same. Likewise, the guiding groove and/or the rail can also be provided with at least one interruption or recess 10 . The interruption portion of the guiding groove may be a wall recess of a material which does not hinder the sliding displacement of the continuous rail 12, 12' and is not in the horizontal plane of the interrupted guiding groove. The sliding displacement of the guide rail 12" interrupted by a recess 10 is hindered.
參考圖7，其顯示根據圖1的頂部皮圈架1"之第四實施例，該十字頭2'具有導引溝槽11'，該等導引溝槽係在各部份中藉由延伸於該水平面中之壁凹18所中斷。於此變型中，該導條皮圈3之連續式導軌12亦僅只停靠在該導引溝槽11'的無中斷部份上之二位置。Referring to Figure 7, there is shown a fourth embodiment of the top apron frame 1" according to Figure 1, the crosshead 2' having a guiding groove 11' extending in each portion by extension The recess 18 in the horizontal plane is interrupted. In this variant, the continuous guide rail 12 of the guide apron 3 also rests only at two positions on the uninterrupted portion of the guide groove 11'.
最後，該二變型的一組合係亦可能的，其中該導軌及該導引溝槽兩者皆具有呈壁凹之形式的中斷部。Finally, a combination of the two variants is also possible, wherein both the guide rail and the guide groove have an interruption in the form of a wall recess.
於操作期間及於該操作狀態之變化期間，用於穩定根據該第三或第四實施例之導條皮圈、或來自該二實施例之導條皮圈及十字頭的組合之先決條件，係該等導引元件總是以此一使得該導條皮圈相對於該水平面之傾斜可被避免的方式彼此接觸。Prerequisites for stabilizing the combination of the guide apron according to the third or fourth embodiment, or the guide apron and crosshead from the second embodiment during operation and during the change of the operational state, The guiding elements are always in contact with each other in such a way that the inclination of the guide aprons relative to the horizontal plane can be avoided.
