Description
本發明關於一種印表機,尤指一種可防止發生卡刀(cutter jam)之印表機。The present invention relates to a printer, and more particularly to a printer that prevents the occurrence of a cutter jam.
連續供紙印表機,如熱感應式印表機,大部分都有提供列印後自動裁紙功能。大部分的裁紙機構都是將移動刀組安裝於印表機殼體上且將固定刀組安裝於可開啟的上蓋上,以利用移動刀組與固定刀組相互配合來裁紙。然而,若固定刀組偏離工作位置,上述裁紙機構便會有發生卡刀的機率。請參閱第1圖,第1圖為先前技術之印表機3的內部示意圖。如第1圖所示,印表機3包含一固定刀組32以及一移動刀組34。由於固定刀組32偏離工作位置,因此,移動刀組34之移動刀片340在朝向固定刀組32之固定刀片320移動進行裁紙時,移動刀片340便會***固定刀片320下方間隙,而發生卡刀。此外,若紙張於固定刀組32與移動刀組34間發生擠壓,或是有堅硬異物存在固定刀組32與移動刀組34之間,上述裁紙機構亦會有發生卡刀的機率。目前,先前技術只能在發生卡刀時,藉由複雜的機構設計來排除卡刀,而無法防止卡刀發生。Continuous paper feed printers, such as thermal printers, provide automatic paper cutting after printing. Most of the paper cutting mechanisms mount the moving knife set on the printer housing and mount the fixed knife set on the openable upper cover to cooperate with the fixed knife set to cut the paper. However, if the fixed knife set is deviated from the working position, the above-mentioned cutting mechanism may have a probability of occurrence of a card cutter. Please refer to FIG. 1. FIG. 1 is a schematic diagram of the internal structure of the prior art printer 3. As shown in FIG. 1, the printer 3 includes a fixed knife set 32 and a moving knife set 34. Since the fixed blade set 32 is offset from the working position, when the moving blade 340 of the moving blade set 34 moves toward the fixed blade 320 of the fixed blade set 32 for cutting, the moving blade 340 is inserted into the gap below the fixed blade 320, and the card is generated. Knife. Further, if the paper is squeezed between the fixed blade set 32 and the movable blade set 34, or if there is a hard foreign matter between the fixed blade set 32 and the movable blade set 34, the above-mentioned paper cutting mechanism may also have a probability of occurrence of a card cutter. At present, the prior art can only eliminate the card cutter by a complicated mechanism design when the card cutter occurs, and cannot prevent the card cutter from occurring.
本發明的目的之一在於提供一種可防止發生卡刀之印表機,以解決上述問題。One of the objects of the present invention is to provide a printer capable of preventing the occurrence of a card cutter to solve the above problems.
根據一實施例,本發明之印表機包含一殼體、一固定刀組以及一移動刀組。固定刀組設置於殼體中且位於一工作位置。固定刀組包含一固定刀片以及一第一支架,其中固定刀片設置於第一支架上,且第一支架具有一擋止部。移動刀組設置於殼體中且與固定刀組相對。移動刀組包含一移動刀片以及一第二支架,其中移動刀片可移動地設置於第二支架上,且移動刀片具有一突出部。擋止部與固定刀片之一刀刃間之一垂直距離小於移動刀片之一垂直高度。在移動刀片接觸固定刀片前,擋止部與移動刀片間之一水平距離小於或等於固定刀片與移動刀片間之一水平距離。According to an embodiment, the printer of the present invention includes a housing, a stationary knife set, and a moving knife set. The fixed knife set is disposed in the housing and is located in a working position. The fixed knife set includes a fixed blade and a first bracket, wherein the fixed blade is disposed on the first bracket, and the first bracket has a stopping portion. The moving knife set is disposed in the housing and opposite to the fixed knife set. The moving knife set includes a moving blade and a second bracket, wherein the moving blade is movably disposed on the second bracket, and the moving blade has a protrusion. The vertical distance between the stop and one of the blades of the stationary blade is less than the vertical height of one of the moving blades. The horizontal distance between the stop and the moving blade is less than or equal to a horizontal distance between the fixed blade and the moving blade before the moving blade contacts the fixed blade.
綜上所述,本發明係於固定刀組之支架上增設擋止部。因此,當固定刀組偏離工作位置而位於偏離範圍中時,擋止部即可將移動刀片擋住,以防止移動刀片***固定刀片下方的間隙而發生卡刀。此外,擋止部與固定刀片之刀刃間之垂直距離小於移動刀片之垂直高度,可確保移動刀片也不會***固定刀片與擋止部之間的間隙。再者,擋止部與移動刀片間之水平距離小於固定刀片與移動刀片間之水平距離,可確保當固定刀組偏離工作位置而位於偏離範圍中時,移動刀片在接觸固定刀片前即被擋止部擋住,以防止移動刀片與固定刀片因碰撞而毀損。同理,擋止部與移動刀片間之水平距離亦可選擇性地等於固定刀片與移動刀片間之水平距離,可確保當固定刀組偏離工作位置而位於偏離範圍中時,移動刀片在接觸固定刀片的同時即被擋止部擋住,同樣可防止移動刀片與固定刀片因碰撞而毀損。In summary, the present invention is to add a stop portion to the bracket of the fixed knife set. Therefore, when the fixed blade group is deviated from the working position and is located in the deviation range, the stopper portion can block the moving blade to prevent the moving blade from being inserted into the gap below the fixed blade to cause the card cutter. In addition, the vertical distance between the stop portion and the blade of the stationary blade is smaller than the vertical height of the moving blade, ensuring that the moving blade is not inserted into the gap between the fixed blade and the stopper. Moreover, the horizontal distance between the stopping portion and the moving blade is smaller than the horizontal distance between the fixed blade and the moving blade, which ensures that when the fixed blade is deviated from the working position and is in the deviation range, the moving blade is blocked before contacting the fixed blade. The stop is blocked to prevent the moving blade and the fixed blade from being damaged by the collision. Similarly, the horizontal distance between the stopping portion and the moving blade can also be selectively equal to the horizontal distance between the fixed blade and the moving blade, which ensures that the moving blade is fixed in contact when the fixed blade is deviated from the working position and is in the deviation range. The blade is blocked by the stopper at the same time, which also prevents the moving blade and the fixed blade from being damaged by the collision.

The fixed blade 120 can be disposed on the fixing member 126 by being snapped or otherwise, and the fixing member 126 can be screwed or Other ways are provided on the first bracket 122. In this embodiment, the first bracket 122 has a stopping portion 124, and the fixing member 126 has a fixing portion 1260. The fixing portion 1260 can be bent and formed from the front of the fixing member 126 to clamp the blade 128 of the fixed blade 120.

The moving blade set 14 includes a moving blade 140 and a second bracket 142, wherein the moving blade 140 is movably disposed on the second bracket 142, and the moving blade 140 has a protrusion 144. In this embodiment, the two sides of the first bracket 122 can respectively have a stopping portion 124, and the two sides of the moving blade 140 can respectively have a protruding portion 144, wherein the position of the stopping portion 124 and the position of the protruding portion 144 Corresponding. It should be noted that the number and position of the blocking portion 124 and the protruding portion 144 may correspond to each other, and are not limited to the embodiment shown in the drawings.
如第8圖所示,印表機1可另包含一驅動裝置16、一感應器18以及一處理器20。驅動裝置16設置於殼體10中且連接於移動刀片140。於此實施例中,驅動裝置16可由馬達、齒輪組與傳動軸組成,用以驅動移動刀片140移動。感應器18設置於殼體10中且設置於第二支架142上,用以感應移動刀片140之一移動時間。於此實施例中,感應器18可為光學式感應器或機械式感應器,視實際應用而定。處理器20設置於殼體10中且電性連接於驅動裝置16與感應器18。於實際應用中,印表機1中還會設有運作時必要的軟硬體元件,如電路板、記憶體、電源供應器、應用程式、通訊模組等,視實際應用而定。As shown in FIG. 8, the printer 1 can further include a driving device 16, an inductor 18, and a processor 20. The driving device 16 is disposed in the housing 10 and is coupled to the moving blade 140. In this embodiment, the drive unit 16 may be comprised of a motor, a gear set, and a drive shaft for driving the moving blade 140 to move. The sensor 18 is disposed in the housing 10 and disposed on the second bracket 142 for sensing a moving time of the moving blade 140. In this embodiment, the inductor 18 can be an optical sensor or a mechanical sensor, depending on the application. The processor 20 is disposed in the housing 10 and electrically connected to the driving device 16 and the inductor 18 . In practical applications, the printer 1 will also have the necessary hardware and software components for operation, such as circuit boards, memory, power supplies, applications, communication modules, etc., depending on the application.
如第5圖所示,當固定刀組12位於工作位置時,擋止部124與固定刀片120之一刀刃128間之一垂直距離VD小於移動刀片140之一垂直高度VH。此外,在移動刀片140接觸固定刀片120前,擋止部124與移動刀片140間之一水平距離HD1小於固定刀片120與移動刀片140間之一水平距離HD2。換言之,在移動刀片140接觸固定刀片120前,擋止部124係位於移動刀片140與固定刀片120之間。擋止部124可位於固定部1260前方且與固定部1260鄰接。再者,擋止部124之一最高點130相對於殼體10底部具有一第一高度H1,且移動刀片140相對於殼體10底部具有一第二高度H2。當固定刀組12位於工作位置時,第一高度H1係低於第二高度H2。換言之,當固定刀組12位於工作位置時,擋止部124係位於移動刀片140之水平延伸線的下方。As shown in FIG. 5, when the fixed blade set 12 is in the operating position, a vertical distance VD between the stop portion 124 and one of the blades 128 of the stationary blade 120 is less than a vertical height VH of the moving blade 140. Further, a horizontal distance HD1 between the stopper portion 124 and the moving blade 140 is smaller than a horizontal distance HD2 between the fixed blade 120 and the moving blade 140 before the moving blade 140 contacts the fixed blade 120. In other words, the blocking portion 124 is located between the moving blade 140 and the stationary blade 120 before the moving blade 140 contacts the fixed blade 120. The stopper portion 124 may be located in front of the fixing portion 1260 and adjacent to the fixing portion 1260. Moreover, one of the highest points 130 of the stop portion 124 has a first height H1 with respect to the bottom of the housing 10, and the moving blade 140 has a second height H2 with respect to the bottom of the housing 10. When the fixed knife set 12 is in the working position, the first height H1 is lower than the second height H2. In other words, when the fixed blade set 12 is in the operative position, the stops 124 are located below the horizontal extension of the moving blade 140.
當固定刀組12位於工作位置,且處理器20控制驅動裝置16驅動移動刀片140朝固定刀片120移動時,由於擋止部124係位於移動刀片140之水平延伸線的下方,因此,擋止部124不會與移動刀片140產生干涉,如第6圖所示。因此,移動刀片140可持續前進以抵壓固定刀片120,進而與固定刀片120相互配合來裁紙。當固定刀組12位於工作位置時,若由前視角度描述固定刀片120,固定刀片120呈現拱狀外型,固定刀片120的兩端部分相對較低並藉由固定件126設置於第一支架122上,而固定刀片120的中間部分相對較高。若由前視角度描述移動刀片140時,移動刀片140之突出部144位於移動刀片140之兩端,移動刀片140之其它部分則呈現扁平狀。而若由俯視角度觀描述移動刀片140時,移動刀片140之前緣呈現V字型的刀刃,移動刀片140的刀刃兩端部分相對向前延伸,移動刀片140之突出部144通常即位於移動刀片140的刀刃兩端相對向前延伸的部分,而移動刀片140的刀刃中間部分則相對向後內縮,如第4圖所示。當固定刀組12位於工作位置,在移動刀片140的刀刃尚未接觸固定刀片120的刀刃時,移動刀片140之水平延伸線係高於固定刀片120的兩端部分而低於固定刀片120的中間部分。當移動刀片140被驅動朝固定刀片120移動以致移動刀片140的刀刃逐漸接觸固定刀片120的刀刃而可裁紙時,係由移動刀片140之突出部144自固定刀片120的兩端部分持續向下推抵固定刀片120,固定刀片120產生形變,且固定刀片120的刀刃被移動刀片140的刀刃接觸的部位由固定刀片120的兩端逐移動或漸延伸到固定刀片120的中間,進而完成裁紙。前述關於固定刀片120與移動刀片140的外型以及二者接觸之裁紙行程係為習知技藝之人所熟知,其它細節在此不再贅述。When the fixed blade set 12 is in the working position, and the processor 20 controls the driving device 16 to drive the moving blade 140 to move toward the fixed blade 120, since the stopping portion 124 is located below the horizontal extension line of the moving blade 140, the stopping portion 124 does not interfere with the moving blade 140, as shown in FIG. Therefore, the moving blade 140 can continue to advance against the fixed blade 120, thereby cooperating with the fixed blade 120 to cut the paper. When the fixed blade set 12 is in the working position, if the fixed blade 120 is described by the front view angle, the fixed blade 120 has an arched outer shape, and both end portions of the fixed blade 120 are relatively low and are disposed on the first bracket by the fixing member 126. 122, while the middle portion of the stationary blade 120 is relatively high. If the moving blade 140 is described by a front view angle, the protruding portion 144 of the moving blade 140 is located at both ends of the moving blade 140, and the other portions of the moving blade 140 are flat. When the moving blade 140 is described from a top view, the leading edge of the moving blade 140 presents a V-shaped blade, and both end portions of the blade of the moving blade 140 extend relatively forward, and the protruding portion 144 of the moving blade 140 is usually located at the moving blade 140. The ends of the blade are relatively forwardly extended, and the intermediate portion of the blade of the moving blade 140 is retracted relatively rearward, as shown in FIG. When the fixed blade set 12 is in the working position, when the blade of the moving blade 140 has not touched the blade of the fixed blade 120, the horizontal extending line of the moving blade 140 is higher than the both end portions of the fixed blade 120 and lower than the middle portion of the fixed blade 120. . When the moving blade 140 is driven to move toward the fixed blade 120 such that the blade of the moving blade 140 gradually contacts the blade of the fixed blade 120 to cut the paper, the protruding portion 144 of the moving blade 140 continues downward from both ends of the fixed blade 120. Pushing against the fixed blade 120, the fixed blade 120 is deformed, and the portion of the blade of the fixed blade 120 that is contacted by the blade of the moving blade 140 is moved or gradually extended from the both ends of the fixed blade 120 to the middle of the fixed blade 120, thereby completing the cutting. . The aforementioned cutting path for the fixed blade 120 and the moving blade 140 and the contact between the two are well known to those skilled in the art, and other details are not described herein.
若紙張(未顯示)於固定刀片120與移動刀片140間發生擠壓,或是有堅硬異物存在固定刀片120與移動刀片140之間,則固定刀片120與移動刀片140便會有發生卡刀的機率。此時,處理器20可根據感應器18所感應的移動刀片140之移動時間來判斷是否發生卡刀。當移動時間大於一預定時間時,表示裁紙發生異常,亦即有可能已經發生卡刀。此時,處理器20可控制驅動裝置16反轉,以使移動刀片140朝遠離固定刀片120之方向移動,進而排除卡刀的情況。藉此,即可防止固定刀片120與移動刀片140因卡刀而毀損。上述之預定時間可為移動刀片140於正常情況下完成一次裁紙所需的時間(例如,0.5秒),視不同的機種而定。If the paper (not shown) is squeezed between the fixed blade 120 and the moving blade 140, or if there is a hard foreign matter between the fixed blade 120 and the moving blade 140, the fixed blade 120 and the moving blade 140 may have a card cutter. Probability. At this time, the processor 20 can determine whether a card cutter occurs according to the moving time of the moving blade 140 sensed by the sensor 18. When the moving time is greater than a predetermined time, it indicates that the paper cutting is abnormal, that is, the card cutter may have occurred. At this time, the processor 20 can control the reverse rotation of the driving device 16 to move the moving blade 140 away from the fixed blade 120, thereby eliminating the condition of the card cutter. Thereby, it is possible to prevent the fixed blade 120 and the moving blade 140 from being damaged by the card cutter. The predetermined time mentioned above may be the time (for example, 0.5 seconds) required for the moving blade 140 to complete the paper cutting under normal conditions, depending on the model.
請參閱第9圖至第11圖,第9圖為第2圖中的上蓋100稍微翹起的示意圖,第10圖為第9圖中的印表機1的內部示意圖,第11圖為第10圖中的印表機1的局部側視圖。當上蓋100未蓋好而稍微翹起時(如第9圖所示),固定刀組12即會隨著上蓋100稍微翹起而偏離工作位置(如第11圖所示)。如第10圖所示,本發明可自移動刀片140朝固定刀片120定義一投影方向PD。當固定刀組12偏離工作位置而位於一偏離範圍中時,擋止部124於投影方向PD上之一投影與突出部144於投影方向PD上之一投影至少部分重疊。因此,當固定刀組12偏離工作位置而位於偏離範圍中時,擋止部124即可將移動刀片140擋住(如第11圖所示),以防止移動刀片140***固定刀片120下方的間隙而發生卡刀。需說明的是,本發明可以固定刀組12之工作位置與移動刀片140之突出部144來定義上述之偏離範圍,如第5圖中的偏離範圍R所示。Please refer to FIG. 9 to FIG. 11 , FIG. 9 is a schematic view showing the upper cover 100 slightly tilted in FIG. 2 , and FIG. 10 is a schematic view of the inside of the printer 1 in FIG. 9 , and FIG. 11 is the tenth. A partial side view of the printer 1 in the drawing. When the upper cover 100 is not covered and slightly tilted (as shown in Fig. 9), the fixed blade set 12 is deviated from the working position as the upper cover 100 is slightly tilted (as shown in Fig. 11). As shown in FIG. 10, the present invention can define a projection direction PD from the moving blade 140 toward the stationary blade 120. When the fixed blade set 12 is offset from the working position and lies in an offset range, one of the projections of the blocking portion 124 in the projection direction PD at least partially overlaps with one of the projections 144 in the projection direction PD. Therefore, when the fixed blade set 12 is deviated from the working position and is in the deviation range, the stopping portion 124 can block the moving blade 140 (as shown in FIG. 11) to prevent the moving blade 140 from being inserted into the gap below the fixed blade 120. A card cutter has occurred. It should be noted that the present invention can define the working position of the blade set 12 and the protruding portion 144 of the moving blade 140 to define the above-mentioned deviation range, as shown by the deviation range R in FIG.
此外,由於擋止部124與固定刀片120之刀刃128間之垂直距離VD小於移動刀片140之垂直高度VH(如第5圖所示),當固定刀組12偏離工作位置而位於偏離範圍中時,可確保移動刀片140也不會***固定刀片120與擋止部124之間的間隙。再者,由於擋止部124與移動刀片140間之水平距離HD1小於固定刀片120與移動刀片140間之水平距離HD2(如第5圖所示),可確保移動刀片140在接觸固定刀片120前即被擋止部124擋住,以防止移動刀片140與固定刀片120因碰撞而毀損。更甚者,由於擋止部124位於固定部1260前方且與固定部1260鄰接,擋止部124除了可防止發生卡刀外,在生產過程中將固定刀片120組裝於固定件126上時、移動刀片140接觸並向下抵壓固定刀片120以進行裁紙時或在其它情況中,擋止部124亦可防止固定部1260朝移動刀片140的方向過度彎折變形而使固定刀片120發生脫落。Further, since the vertical distance VD between the stopper portion 124 and the blade 128 of the fixed blade 120 is smaller than the vertical height VH of the moving blade 140 (as shown in FIG. 5), when the fixed blade group 12 is deviated from the working position and is in the deviation range It is ensured that the moving blade 140 is also not inserted into the gap between the fixed blade 120 and the stopper 124. Moreover, since the horizontal distance HD1 between the stopping portion 124 and the moving blade 140 is smaller than the horizontal distance HD2 between the fixed blade 120 and the moving blade 140 (as shown in FIG. 5), the moving blade 140 can be ensured before contacting the fixed blade 120. That is, it is blocked by the stopper portion 124 to prevent the moving blade 140 and the fixed blade 120 from being damaged by the collision. Moreover, since the stopper portion 124 is located in front of the fixing portion 1260 and is adjacent to the fixing portion 1260, the stopper portion 124 can move the fixing blade 120 to the fixing member 126 during the production process, in addition to preventing the occurrence of the card cutter. When the blade 140 contacts and presses the fixed blade 120 downward to cut the paper or in other cases, the stopper portion 124 can also prevent the fixing portion 1260 from being excessively bent and deformed toward the moving blade 140 to cause the fixed blade 120 to fall off.
需說明的是,本發明亦可使擋止部124與固定部1260錯位,而使擋止部124位於固定刀片120下方,亦即,使擋止部124之外表面與固定刀片120之刀刃128共平面。此時,在移動刀片140接觸固定刀片120前,擋止部124與移動刀片140間之水平距離HD1即等於固定刀片120與移動刀片140間之水平距離HD2,以確保當固定刀組12偏離工作位置而位於偏離範圍中時,移動刀片140在接觸固定刀片120的同時即被擋止部124擋住,同樣可防止移動刀片140與固定刀片120因碰撞而毀損。It should be noted that the present invention can also dislocate the blocking portion 124 from the fixing portion 1260, and the blocking portion 124 is located below the fixed blade 120, that is, the outer surface of the blocking portion 124 and the blade 128 of the fixed blade 120. Coplanar. At this time, before the moving blade 140 contacts the fixed blade 120, the horizontal distance HD1 between the stopping portion 124 and the moving blade 140 is equal to the horizontal distance HD2 between the fixed blade 120 and the moving blade 140 to ensure that the fixed blade set 12 deviates from the work. When the position is in the deviation range, the moving blade 140 is blocked by the stopper portion 124 while contacting the fixed blade 120, and the moving blade 140 and the fixed blade 120 are also prevented from being damaged by the collision.
綜上所述,本發明係於固定刀組之支架上增設擋止部。因此,當固定刀組偏離工作位置而位於偏離範圍中時,擋止部即可將移動刀片擋住,以防止移動刀片***固定刀片下方的間隙而發生卡刀。此外,擋止部與固定刀片之刀刃間之垂直距離小於移動刀片之垂直高度,可確保移動刀片也不會***固定刀片與擋止部之間的間隙。再者,擋止部與移動刀片間之水平距離小於固定刀片與移動刀片間之水平距離,可確保當固定刀組偏離工作位置而位於偏離範圍中時,移動刀片在接觸固定刀片前即被擋止部擋住,以防止移動刀片與固定刀片因碰撞而毀損。同理,擋止部與移動刀片間之水平距離亦可選擇性地等於固定刀片與移動刀片間之水平距離,可確保當固定刀組偏離工作位置而位於偏離範圍中時,移動刀片在接觸固定刀片的同時即被擋止部擋住,同樣可防止移動刀片與固定刀片因碰撞而毀損。 以上所述僅為本發明之較佳實施例,凡依本發明申請專利範圍所做之均等變化與修飾,皆應屬本發明之涵蓋範圍。In summary, the present invention is to add a stop portion to the bracket of the fixed knife set. Therefore, when the fixed blade group is deviated from the working position and is located in the deviation range, the stopper portion can block the moving blade to prevent the moving blade from being inserted into the gap below the fixed blade to cause the card cutter. In addition, the vertical distance between the stop portion and the blade of the stationary blade is smaller than the vertical height of the moving blade, ensuring that the moving blade is not inserted into the gap between the fixed blade and the stopper. Moreover, the horizontal distance between the stopping portion and the moving blade is smaller than the horizontal distance between the fixed blade and the moving blade, which ensures that when the fixed blade is deviated from the working position and is in the deviation range, the moving blade is blocked before contacting the fixed blade. The stop is blocked to prevent the moving blade and the fixed blade from being damaged by the collision. Similarly, the horizontal distance between the stopping portion and the moving blade can also be selectively equal to the horizontal distance between the fixed blade and the moving blade, which ensures that the moving blade is fixed in contact when the fixed blade is deviated from the working position and is in the deviation range. The blade is blocked by the stopper at the same time, which also prevents the moving blade and the fixed blade from being damaged by the collision. The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
