Description
本發明涉及一種縫紉機結構,特別涉及一種曲臂式縫紉機結構。The present invention relates to a sewing machine structure, and more particularly to a crank arm type sewing machine structure.
首先,本案所謂的「曲臂式縫紉機」,其結構的特性或功能,主要在於它可將兩塊布的邊緣相併後而再加以縫合,因此業界亦有人稱它為「併縫用縫紉機」或「併縫縫紉機」;然而,還因為它通常是以四針六線(含底線)來加以車縫,因此它亦常被業界稱為「四針六線併縫機」或「四針六線縫紉機」。First of all, the so-called "crank-arm sewing machine" in this case has the structural characteristics or functions mainly because it can join the edges of the two pieces of cloth and then suture them. Therefore, it is also called "sewing sewing machine" in the industry. Or "co-sewing sewing machine"; however, because it is usually sewn with four stitches and six threads (including the bottom line), it is often referred to by the industry as "four-needle six-wire sewing machine" or "four-needle six". Line sewing machine."
再則,與本案技術領域相關的現有技術,請參閱「圖1」與「圖2」所示,如圖所示可清楚看出,所述現有曲臂式縫紉機10係藉由一機座100固設於桌面,該現有曲臂式縫紉機10至少包括一主機殼11與一位於該主機殼11下方的下機殼12,該現有曲臂式縫紉機10係藉由一設於該主機殼11末端的驅動馬達80所帶動;其中,該下機殼12上具有一車縫平台121,該車縫平台121末端具一車縫區13。然而,若能詳細觀察「圖1」所示現有曲臂式縫紉機的使用樣態示意圖,以及「圖2」所示現有曲臂式縫紉機的使用者視角外觀示意圖即可以發現,該現有曲臂式縫紉機10的外殼結構設計上,確實存在有以下的缺陷:一、由於該現有曲臂式縫紉機10的該下機殼12是由該主機殼11直接向下設置的,因此在車縫時使用者觀看至該車縫區13的視線,完全被該主機殼11前端給阻擋,令使用者必須經常將身體或頭部保持向左傾的坐姿,故常令使用者發生脊椎側彎所導致的身體病痛狀況;二、亦由於該現有曲臂式縫紉機10的該主機殼11前端完全阻擋了使用者觀看至該車縫區13的視線,所以常令使用者無法較精確地加以車縫,甚至常造成使用者不慎將手指伸入該車縫區13而受傷的嚴重問題發生。如是,該現有曲臂式縫紉機10長期以來存有根深柢固的外殼結構設計偏見,以及內部機構配置的技術偏見,確實難以符合使用者的需求。所以,如何才能在車縫工作時讓使用者維持良好坐姿,以及如何才能讓使用者在車縫時可以更安全的工作,實為此項技術相關業者當務之急。Furthermore, referring to the prior art related to the technical field of the present invention, please refer to FIG. 1 and FIG. 2, as is clear from the figure, the conventional crank-type sewing machine 10 is provided by a base 100. Fixed on the table top, the conventional crank-type sewing machine 10 includes at least a main casing 11 and a lower casing 12 located below the main casing 11, the conventional crank-type sewing machine 10 being disposed on the mainframe The driving motor 80 at the end of the casing 11 is driven; wherein the lower casing 12 has a sewing platform 121, and the sewing platform 121 has a sewing zone 13 at the end. However, if you can observe in detail the usage diagram of the existing crank-arm sewing machine shown in Fig. 1 and the user's perspective view of the existing crank-arm sewing machine shown in Fig. 2, the existing crank arm type can be found. The outer casing structure of the sewing machine 10 is designed to have the following drawbacks: 1. Since the lower casing 12 of the conventional crank-type sewing machine 10 is directly disposed downward from the main casing 11, it is used in sewing. The line of sight of the sewing area 13 is completely blocked by the front end of the main casing 11, so that the user must always keep the body or the head in a sitting position inclined to the left, so that the user often causes the body to be caused by the scoliosis. The condition of the illness; secondly, because the front end of the main casing 11 of the existing crank-type sewing machine 10 completely blocks the line of sight viewed by the user to the sewing area 13, the user often cannot accurately sewn the seam, even A serious problem that often causes a user to accidentally push a finger into the sewing area 13 occurs. If so, the existing crank-arm sewing machine 10 has long existed a deep-deep sturdy outer casing structural design bias, and the technical bias of the internal mechanism configuration, it is indeed difficult to meet the needs of users. Therefore, how to maintain the user's good sitting posture during the sewing work and how to make the user work safer when sewing, is a top priority for this technology-related industry.
另請參閱TW專利公告第M508561號的「縫紉機揚線凸輪裝置」的現有技術,所述縫紉機的該揚線凸輪裝置,包括一上飾線機構,該上飾線機構被設置於該縫紉機的該上機臂內部,該上飾線機構是由一上飾線提線凸輪、一第一固定板、一導線桿托架與一上飾線導線桿所組成,該上飾線提線凸輪被支承於該縫紉機的該上機臂的一傳動主軸所貫穿,且固定於該傳動主軸上,該揚線凸輪裝置還包括一底線機構,該底線機構被設置於該縫紉機的該上機臂外部,該底線機構是由一第一固定座、一底線提線凸輪、一第一固定軸、一第二固定座、一壓鈕、一簧片、一第二固定板、一下勾針提線導引架、一導線板、一彈簧、一棘輪與一第二固定軸所組成,該第二固定板可於該第二固定座上進行三段的角度調整,該揚線凸輪裝置還包括一第一時規皮帶輪,該第一時規皮帶輪被支承於該縫紉機的該上機臂的該傳動主軸所貫穿並固定,該揚線凸輪裝置還包括一第二時規皮帶輪,該第二時規皮帶輪固定於該底線提線凸輪的一側,同時被該第一固定軸貫穿,該揚線凸輪裝置還包括一時規皮帶,該時規皮帶分別與該第一時規皮帶輪及該第二時規皮帶輪嚙合。由前述現有技術內容可得知,該縫紉機在縫製過程的每一縫製行程中,底線必須利用該底線提線凸輪配合揚弛一次,以達成該底線可被該縫紉機餵線與調整其鬆緊度的目的。而由於該現有技術的揚線凸輪裝置是設置於該縫紉機的該上機臂殼體內部,因此常使用者在穿設底線時,則必須將該上機臂的殼體打開,然而,因為該上機臂的殼體內部機構較多且空間非常狹小,故常令使用者的手指不易進入穿設底線,使用者往往另需藉由其他輔助工具方可將該底線完成穿設的動作;所以,由上述可很清楚看出,此種設於縫紉機上機臂殼體內部的該揚線凸輪裝置設計,確實令使用者在換裝底線時造成不便與極大的困擾;再則,若該底線不慎發生斷線的狀況,此時因斷線所形成的線頭,即會被持續旋轉中的該揚線凸輪裝置所拉扯而纏絞在兩片該底線提線凸輪等零組件間隙內的軸柱上,使用者若不想以浩大的工程而將該底線提線凸輪等零組件拆下來去除所纏絞的底線,就必須使用有如美工刀般的扁薄形工具,在極為窘迫的狹窄空間內辛苦地挑剔除所纏絞的底線;然而,雖使用者利用該扁薄形工具來深入零組件間隙內將纏絞的底線割斷方式較為方便,但當該扁薄形工具在割斷纏線的同時,亦因該扁薄形工具可能有著銳利的邊鋒,故當操作稍有不慎,就可能造成該底線提線凸輪等零組件被銳利的邊鋒劃出割痕的問題出現,此割痕在日後該底線提線凸輪等零組件運作時將造成該底線斷線頻率升高的主因;因此,不論上述現有技術以任何方式來清除所纏絞的底線,均相當耗時且非常費工,更嚴重的是,當在清除纏線的期間此機台勢必得停工,業者若無備用機台來有效地調度工作人員立即再加入生產,將造成生產量降低的問題,更可能影響至業者的產品交貨期,此實為車縫產品加工廠商的一大夢魘與困擾。由此可知,在曲臂式縫紉機的技術領域中,長久以來該現有技術的相關業者,對於揚線凸輪裝置的裝設位置與其構造的技術偏見已是根深柢固,但事實上該現有技術的確已不符使用者所需。所以,如何才能讓使用者可更輕易、更快速地清除上述零組件間隙內所纏絞的底線,以及如何才能讓使用者可更簡易、更方便地重新穿設該底線,同樣為此項技術相關業者當務之急。Please refer to the prior art of "Sewing Machine Flying Cam Device" of TW Patent Publication No. M508561, wherein the wire cam device of the sewing machine includes an upper threading mechanism, and the upper threading mechanism is disposed on the sewing machine. Inside the upper arm, the upper trimming mechanism is composed of an upper trim wire lifting cam, a first fixing plate, a wire rod bracket and an upper trim wire guide rod, and the upper trim wire lifting cam is supported a drive shaft of the upper arm of the sewing machine is penetrated and fixed to the drive spindle, the line cam device further includes a bottom thread mechanism, the bottom thread mechanism is disposed outside the upper arm of the sewing machine, The bottom wire mechanism is composed of a first fixing seat, a bottom wire lifting cam, a first fixing shaft, a second fixing seat, a pressing button, a reed, a second fixing plate, and a lower hook lifting guide. a wire plate, a spring, a ratchet wheel and a second fixed shaft, the second fixing plate can perform three-stage angle adjustment on the second fixing seat, and the wire cam device further includes a first time Regulating pulley, the first timing pulley The transmission main shaft supported by the upper arm of the sewing machine is penetrated and fixed, the line cam device further includes a second timing pulley, and the second timing pulley is fixed to one side of the bottom wire lifting cam, Passed by the first fixed shaft, the line cam device further includes a timing belt that meshes with the first timing pulley and the second timing pulley, respectively. It can be known from the foregoing prior art that in the sewing process of the sewing machine, the bottom thread must be extended by the bottom wire lifting cam to achieve the bottom thread can be fed by the sewing machine and adjust the tightness thereof. purpose. Since the prior art sling cam device is disposed inside the upper arm housing of the sewing machine, the user must open the upper arm when the bottom thread is worn. However, because The inner arm of the upper arm has many internal mechanisms and the space is very narrow. Therefore, the user's fingers are not easy to enter the bottom line, and the user often needs other auxiliary tools to complete the laying of the bottom line; therefore, It can be clearly seen from the above that the design of the cable cam device disposed inside the arm housing of the sewing machine does cause inconvenience and great trouble to the user when the bottom line is changed. Further, if the bottom line is not The condition of disconnection is cautious. At this time, the wire end formed by the broken wire is pulled by the wire cam device that is continuously rotated and twisted in the axis of the two component gaps such as the bottom wire lifting cam. On the column, if the user does not want to remove the bottom wire lifting cam and other components to remove the twisted bottom thread with great engineering, it is necessary to use a flat thin tool like a utility knife in a very narrow and narrow space. Difficult to pick and choose the twisted bottom line; however, although the user uses the flat thin tool to penetrate the gap of the component to cut the twisted bottom thread more conveniently, when the flat thin tool cuts the entangled line Also, because the flat thin tool may have a sharp winger, when the operation is slightly careless, it may cause the problem that the bottom wire lifting cam and the like are scratched by the sharp winger, and the cut is in the future. When the components such as the bottom wire lifting cam are operated, the main cause of the bottom wire breaking frequency is increased; therefore, regardless of the above prior art, the winding of the twisted bottom wire is removed in any manner, which is time consuming and laborious, and more serious. The machine is bound to stop working during the process of clearing the entanglement. If the machine has no spare machine to effectively dispatch the staff to join the production immediately, it will cause the production to decrease, which may affect the product delivery of the industry. The delivery period, this is a big nightmare and trouble for the sewing products processing manufacturers. It can be seen that in the technical field of the crank-type sewing machine, the related art of the prior art has long been deeply rooted in the technical position of the installation position and the structure of the cable cam device, but in fact the prior art does Has not met the user's needs. Therefore, how can the user more easily and quickly remove the bottom line wrapped in the gap between the above components, and how to make it easier and more convenient for the user to re-thread the bottom line. Relevant operators are imperative.
