Description

用於圓形針織機的凸輪 Cam for circular knitting machines

本發明涉及一種用於圓形針織機的凸輪，此種凸輪具有至少一個成形於凸輪表面的凸輪槽，其作用是容納及導引線跡形成工具的一個壓腳。 The present invention relates to a cam for a circular knitting machine having at least one cam groove formed on a cam surface for receiving and guiding a presser foot of the stitch forming tool.

用於圓形針織機的凸輪並不只是用於提升線跡形成工具以執行線跡形成操作。此等凸輪的另一個作用是以其表面將線跡成形工具固定於正確的位置。例如，透過這種方式，凸輪可以防止圓形針織機的圓筒針被圓筒旋轉時產生的離心力徑向向外搖擺。在平面圓形針織機內，沉降凸輪可以防止下降片因縫紉力的作用而傾斜。 The cam for a circular knitting machine is not only used to lift the stitch forming tool to perform a stitch forming operation. Another function of these cams is to secure the stitch forming tool in the correct position with its surface. For example, in this manner, the cam can prevent the cylindrical needle of the circular knitting machine from swaying radially outward by the centrifugal force generated when the cylinder is rotated. In a flat circular knitting machine, the settling cam prevents the lowering piece from being tilted by the action of the sewing force.

在以上所有的情況中，線跡形成工具都是被壓在凸輪表面上。由於線跡形成工具會相對於凸輪移動，因此所產生的摩擦力會使線跡形成工具過早被磨壞。此外，摩擦會產生相當大的熱，因此需要耗費更多的能源才能驅動針織機。因此需要潤滑凸輪，以便將摩擦能量保持在盡可能低的程度。 In all of the above cases, the stitch forming tools are pressed against the cam surface. Since the stitch forming tool moves relative to the cam, the friction generated causes the stitch forming tool to be worn out prematurely. In addition, friction generates considerable heat and therefore requires more energy to drive the knitting machine. It is therefore necessary to lubricate the cam in order to keep the frictional energy as low as possible.

本發明的目的是提出凸輪表面與線跡形成工具之間的摩擦較低的凸輪。 It is an object of the present invention to provide a cam having a lower friction between the cam surface and the stitch forming tool.

為達到上述目的，本發明的用於圓形針織機的凸輪具有至少一個成形於凸輪表面的凸輪槽，其作用是容納及導引線跡形成工具的一個壓腳，此種凸輪的特徵是在凸輪表面上形成額外的凹陷，以縮小凸輪表面與線跡形成工具的柄部之間的接觸表面。 In order to achieve the above object, a cam for a circular knitting machine of the present invention has at least one cam groove formed on a cam surface for accommodating and guiding a presser foot of the stitch forming tool, the cam being characterized by Additional depressions are formed in the cam surface to reduce the contact surface between the cam surface and the shank of the stitch forming tool.

在這種情況下，能夠在至少一個凸輪槽內被導引的線跡形成工具可以是針、握持沉降片、下降片、旋轉沉降片、彈簧沉降片、彈簧銷、中間銷、或底腳片選針器。 In this case, the stitch forming tool capable of being guided in the at least one cam groove may be a needle, a holding sinker, a falling piece, a rotating sinker, a spring sinker, a spring pin, a center pin, or a foot. Chip selector.

凸輪表面上的凹陷不只能夠縮小凸輪與線跡形成工具之間的鄰接表面以減少摩擦，也可以減慢潤滑油在凸輪表面上的流動。凹陷形成的油池可搜集潤滑油，以改善潤滑效果。這樣可以進一步減少線跡形成工具與凸輪表面之間的摩擦，達到減少線跡形成工具的磨損及熱的產生。因此可以少需要使用的潤滑油量。 The depression on the cam surface not only reduces the abutment surface between the cam and the stitch forming tool to reduce friction, but also slows the flow of lubricating oil on the cam surface. The oil pool formed by the depression can collect lubricating oil to improve the lubrication effect. This can further reduce the friction between the stitch forming tool and the cam surface, thereby reducing wear and heat generation of the stitch forming tool. Therefore, the amount of lubricating oil that needs to be used can be reduced.

此外，可以按廠商指定的方式製造出個體化的凸輪，而且很容易就可以經由凹陷的類型區分複製品及正廠產品。 In addition, individualized cams can be manufactured in a manner specified by the manufacturer, and it is easy to distinguish between replicas and factory products via the type of recess.

根據凸輪的一種有利的實施方式，凹陷被製作成在線跡形成工具之移動方向上延伸的通道或溝槽。這些凹陷可以減慢潤滑油在凸輪表面從上到下流經凸輪的整個寬度的 速度。在這種實施方式中，通道或溝槽較佳是平行於該至少一個凸輪槽，這樣做的優點是凸輪表面可以提供非常均勻的減少摩擦的凹陷。 According to an advantageous embodiment of the cam, the recess is made as a channel or groove extending in the direction of movement of the stitch forming tool. These depressions can slow the flow of lubricating oil across the entire width of the cam from top to bottom on the cam surface. speed. In such an embodiment, the passage or groove is preferably parallel to the at least one cam groove, which has the advantage that the cam surface can provide a very uniform friction reducing depression.

根據另一種實施方式，通道或溝槽能夠從油噴嘴出口以星形形狀延伸。潤滑油能夠從底部朝上被送到通道或溝槽，因而減少潤滑油的消耗量。 According to another embodiment, the channel or groove can extend in a star shape from the oil nozzle outlet. Lubricating oil can be sent to the passage or groove from the bottom up, thus reducing the consumption of lubricating oil.

也可以使用交叉的通道或溝槽，以使潤滑油的分佈更均勻。 It is also possible to use intersecting channels or grooves to make the distribution of the lubricating oil more uniform.

當然也可以將凹陷設計成其他的形狀，例如將圓柱形、箭形、溝槽形的凹陷配置在均勻的格柵上。 It is of course also possible to design the recesses into other shapes, for example to arrange cylindrical, arrow-shaped, groove-shaped recesses on a uniform grid.

在這種情況下，通道或溝槽的深度可以降低，或是沿著線跡形成工具的移動方向變化。這種設計方式可以對聚集在凹陷中的潤滑油產生抽吸作用，因而改善潤滑效果。 In this case, the depth of the channel or groove may be lowered or may vary along the direction of movement of the stitch forming tool. This design can provide a suction effect on the lubricating oil accumulated in the recess, thereby improving the lubrication effect.

此外，將處於凹陷之間的凸輪表面設計成至少在部分區域是凸面形狀，可以進一步減少凸輪與線跡形成工具之間的摩擦。這會在線跡形成工具與凸輪之間形成僅是點狀的接觸點。潤滑可以聚集在凹陷中。 Further, the cam surface between the recesses is designed to have a convex shape at least in a partial region, and the friction between the cam and the stitch forming tool can be further reduced. This creates a point-like contact point between the line forming tool and the cam. Lubrication can accumulate in the depressions.

當然也可以在一個凸輪內設置多個不同形狀的凹陷。 It is of course also possible to provide a plurality of differently shaped depressions in one cam.

此外，對溝槽或通道平行於凸輪槽平行的凸輪而言，可以使用的平坦投影的線跡形成工具的柄部帶有一個能夠被***一個溝槽或通道的平坦的突出部分，其中這個突出部分較佳是能夠在溝槽或通道內移動，而且不會與觸溝槽或通道產生接觸。如果凸輪未具有能夠與這個突出部分配合的溝槽，則不能與這個線跡形成工具共同運作。而且複 製凸輪的工作也會變困難。 Furthermore, for a cam having a groove or channel parallel to the cam groove, the handle of the flat projection stitch forming tool that can be used has a flat projection that can be inserted into a groove or channel, wherein this projection Part of it is preferred to be able to move within the grooves or channels without coming into contact with the contact grooves or channels. If the cam does not have a groove that can cooperate with this protruding portion, it cannot work with this stitch forming tool. And complex The work of making cams will also become difficult.

第1圖顯示的圓形針織機(未在圖式中繪出)的凸輪10具有一個導引線跡形成工具13的一個壓腳12用的凸輪槽11，第10圖顯示一種可能的實施方式。凸輪槽的行進路線是由線跡形成工具13要執行的上升及回復運動決定。兩個形狀如開闊的淺溝槽的凹陷14，15陷入凸輪10 的表面16，並平行於凸輪槽11。凹陷14，15的作用是縮小凸輪10的表面16與線跡形成工具13的柄部之間的接觸表面。此外，凹陷14，15的另一個作用是減慢潤滑油在凸輪的表面16上朝箭頭18的方向流動的速度。一部分潤滑油會聚集在凹陷14，15，因此凹陷14，15形成一個油池。在柄實施例中，凹陷14，15的深度可以隨著線跡形成工具13的移動方向19變化。 The cam 10 of the circular knitting machine (not shown in the drawings) shown in Fig. 1 has a cam groove 11 for guiding a presser foot 12 of the stitch forming tool 13, and Fig. 10 shows a possible embodiment. . The travel path of the cam groove is determined by the ascending and returning motion to be performed by the stitch forming tool 13. Two recesses 14, 15 shaped like open shallow grooves are trapped in the cam 10 The surface 16 is parallel to the cam groove 11. The function of the recesses 14, 15 is to reduce the contact surface between the surface 16 of the cam 10 and the shank of the stitch forming tool 13. Moreover, another effect of the recesses 14, 15 is to slow the rate at which the lubricating oil flows on the surface 16 of the cam in the direction of the arrow 18. A portion of the lubricating oil will collect in the depressions 14, 15, so that the depressions 14, 15 form an oil sump. In the shank embodiment, the depth of the recesses 14, 15 may vary with the direction of movement 19 of the stitch forming tool 13.

第2圖顯示凸輪20的第二種實施方式，根據這個實施方式，凸輪20除了具有凸輪槽21外，還具有與凸輪表面26平行的通道狀的凹陷22。和凸輪10的溝槽狀凹陷14，15一樣，凹陷22能夠縮小線跡形成工具13與凸輪20的表面26之間的接觸表面。同時，在表面26向下流動的潤滑油有一部分會被聚集到凹陷20的整個寬度中。由於線跡形成工具13與凸輪20之間的摩擦變小，因此需要的潤滑油量會變小，同時驅動圓形針織機所消耗的能源也會變少。 2 shows a second embodiment of the cam 20, according to which, in addition to the cam groove 21, the cam 20 has a channel-like recess 22 parallel to the cam surface 26. Like the groove-like recesses 14, 15 of the cam 10, the recess 22 can reduce the contact surface between the stitch forming tool 13 and the surface 26 of the cam 20. At the same time, a portion of the lubricating oil flowing down the surface 26 will be concentrated into the entire width of the recess 20. Since the friction between the stitch forming tool 13 and the cam 20 becomes small, the amount of lubricating oil required becomes small, and the energy consumed for driving the circular knitting machine is also reduced.

相較於第1圖及第2圖的配置方式，第3圖中的凸輪30具有多個設置在均勻格柵上的盲孔狀凹陷32。凹陷32亦可縮小線跡形成工具13與凸輪30之間的接觸表面，以及聚集流出的潤滑油。 Compared with the arrangement of Figs. 1 and 2, the cam 30 of Fig. 3 has a plurality of blind hole-like recesses 32 provided on the uniform grid. The recess 32 also narrows the contact surface between the stitch forming tool 13 and the cam 30, and collects the lubricating oil flowing out.

第4a及4b圖分別顯示凸輪40及凸輪45，其中凸輪40具有箭形凹陷41，42，凸輪45具有箭形凹陷41，其中凹陷41是朝移動方向43(也就進入凸輪的方向)伸展，凹陷42則是朝反方向伸展。凹陷41，42形成一個油 池。此外，凹陷41，42均為圓錐形，因此能夠對凹陷41中的潤滑油產生一種抽吸作用。朝反方向伸展的凹陷42可以收集流出的潤滑油。如果不使用箭形，亦可將凹陷41，42製作成溝槽狀。 Figures 4a and 4b show the cam 40 and the cam 45, respectively, wherein the cam 40 has arrow-shaped recesses 41, 42 having an arrow-shaped recess 41 in which the recess 41 extends in the direction of movement 43 (i.e., in the direction of the cam). The recess 42 extends in the opposite direction. The depressions 41, 42 form an oil Pool. Further, the recesses 41, 42 are all conical, so that a suction effect can be exerted on the lubricating oil in the recess 41. A recess 42 extending in the opposite direction collects the lubricating oil flowing out. If the arrow shape is not used, the recesses 41, 42 can also be formed into a groove shape.

第5a及5b圖顯示凸輪50，其凹陷被製作成駝峰狀凸起的區域52，作為與線跡形成工具的接觸表面。這樣做可以使線跡形成工具與及凸輪表面之間僅在點狀區域發生磨擦。為了確保能夠均勻的導引線跡形成工具，也可以使駝峰狀凸起的區域52彼此交錯。 Figures 5a and 5b show a cam 50 whose recess is made into a hump-like raised area 52 as a contact surface with the stitch forming tool. This allows friction between the stitch forming tool and the cam surface to be only in the punctiform region. In order to ensure uniform guiding of the stitch forming tool, the hump-like raised regions 52 may be staggered with each other.

第6圖顯示的凸輪60的凹陷是以星形從潤滑油入口或出口61向外伸展的溝槽62。所有的溝槽62都是朝凸輪60的移動方向63向上伸展。因此潤滑油能夠從底部被向上進入溝槽，以減少潤滑油的消耗量。在與凸輪60的移動方向相反的方向上，潤滑油可以從溝槽62流出凸輪60。 The recess of the cam 60 shown in Fig. 6 is a groove 62 that extends outwardly from the lubricating oil inlet or outlet 61 in a star shape. All of the grooves 62 extend upward toward the moving direction 63 of the cam 60. Therefore, the lubricating oil can be moved upward from the bottom into the groove to reduce the consumption of lubricating oil. Lubricating oil may flow out of the cam 60 from the groove 62 in a direction opposite to the moving direction of the cam 60.

第7圖顯示凸輪70的另一種實施方式，其中凸輪70具有水平的溝槽狀的凹陷71。這種凸輪的特色是特別容易製造。 Figure 7 shows another embodiment of the cam 70 in which the cam 70 has a horizontal groove-like recess 71. This cam features a particularly easy to manufacture.

第8圖顯示的凸輪80的凹陷是交錯的直線形溝槽81。這種形式的溝槽81使潤滑能夠均勻的分佈在凸輪表面上。 The depression of the cam 80 shown in Fig. 8 is a staggered linear groove 81. This form of groove 81 allows lubrication to be evenly distributed over the cam surface.

第9c圖顯示如第3圖之凸輪30的一種變化方式。與凸輪30不一樣的是，凸輪30’並不是被製成一個單一構件，而是由基板35(第9a圖)及兩個外殼部件36a、36b 構成(第9b圖)。 Figure 9c shows a variation of the cam 30 as shown in Figure 3. Unlike the cam 30, the cam 30' is not made as a single member but by the base plate 35 (Fig. 9a) and the two outer casing members 36a, 36b. Composition (Fig. 9b).

容納及導引線跡形成工具(未在圖式中繪出)的一個壓腳用的凸輪槽31是形成於基板上。兩個外殼部件36a、36b都帶有盲孔狀的凹陷32，且其固定在基板35上的方式使凸輪槽31暴露在外殼部件36a、36b之間。如果外殼部件36a、36b的厚度較大，凸輪槽31也可以僅配置於外殼部件36a、36b之間，或是配置在一個外殼部件內。因為能夠將不同的外殼部分36a、36b設置在相同的基板35上，因此可以降低凸輪30’的製造成本。 A cam groove 31 for accommodating and guiding a stitch forming tool (not shown in the drawings) is formed on the substrate. Both of the outer casing members 36a, 36b have blind recesses 32 and are secured to the base plate 35 such that the cam grooves 31 are exposed between the outer casing members 36a, 36b. If the thickness of the outer casing members 36a, 36b is large, the cam grooves 31 may be disposed only between the outer casing members 36a, 36b or in one outer casing member. Since the different outer casing portions 36a, 36b can be disposed on the same substrate 35, the manufacturing cost of the cam 30' can be reduced.

製造商也可以利用凸輪10至80的凹陷14，15，22，32，41，42，51，62，71，81將凸輪更為個體化，以使未經授權者自行複製凸輪的工作變得更困難。如第10圖所示，如果線跡形成工具13能夠與凸輪10或凸輪的凹陷14，15個別匹配，則可以進一步防止被人複製。第10圖再次顯示具有凹陷14，15的凸輪10及與其搭配的線跡形成工具13。同樣的，線跡形成工具13有一個壓腳12其中壓腳12在凸輪槽11內被導引，以確保線跡形成工具13的上升及回復運動。此外，線跡形成工具13具有一個突出部分17，當壓腳12被沿著凸輪移動時，突出部分17會與溝槽狀的凹陷14嚙合，並以無摩擦的方式沿著凹陷14移動。 The manufacturer can also use the recesses 14, 15, 22, 32, 41, 42, 51, 62, 71, 81 of the cams 10 to 80 to personalize the cam so that the unauthorized person can copy the cam to work. More difficult. As shown in Fig. 10, if the stitch forming tool 13 can be individually matched with the cams 10 or the recesses 14, 15 of the cam, it can be further prevented from being copied. Figure 10 again shows the cam 10 with the recesses 14, 15 and the stitch forming tool 13 associated therewith. Similarly, the stitch forming tool 13 has a presser foot 12 in which the presser foot 12 is guided in the cam groove 11 to ensure the rising and returning movement of the stitch forming tool 13. Further, the stitch forming tool 13 has a projecting portion 17, which engages with the groove-like recess 14 when the presser foot 12 is moved along the cam, and moves along the recess 14 in a frictionless manner.

由於線跡形成工具13與凸輪10精確匹配，因此不能搭配其他的凸輪(例如凸輪20，30或表面沒有凹陷的傳統式凸輪)使用。 Since the stitch forming tool 13 is precisely matched with the cam 10, it cannot be used in conjunction with other cams (for example, cams 20, 30 or conventional cams having no recess on the surface).
