印表機 Printer

本發明關於一種印表機，尤指一種可將已列印的紙張回捲之印表機。 The invention relates to a printer, and more particularly to a printer capable of rewinding printed paper.

目前，熱感應式印表機已於各種銷售點(point of sales,POS)中被廣泛地用來列印消費單據，例如零售、金融、旅館、醫療等服務行業。熱感應式印表機一般是使用紙捲來進行列印。在某些特定的應用場合中，需要將已列印的紙張回捲，以作為儲存、備份之用，例如***列印存根、電腦投票機投票相關記錄留存等。現有的熱感應式印表機大都需外加一***立的捲紙機，不僅安裝不易，且印表機與捲紙機組合後的體積較大，較佔空間。 At present, thermal-sensing printers have been widely used in various point-of-sales (POS) printing of consumer documents, such as retail, finance, hotels, medical and other service industries. Thermal-sensing printers typically use paper rolls for printing. In some specific applications, the printed paper needs to be rewinded for storage and backup purposes, such as invoice printing stubs, computer voting machine voting related records, and so on. Most of the existing thermal-sensing printers need to be equipped with a separate reeling machine, which is not only difficult to install, but also has a larger volume and a larger space when the printer and the reeling machine are combined.

本發明的目的之一在於提供一種可將已列印的紙張回捲之印表機，以解決上述問題。 One of the objects of the present invention is to provide a printer capable of rewinding printed paper to solve the above problems.

根據一實施例，本發明之印表機包含一供紙滾軸、一驅動裝置、一支架、一收紙機構以及一傳動皮帶。驅動裝置連接於供紙滾軸。收紙機構包含一皮帶輪、一連接件、一傳動件、一摩擦件、一第一彈性件以及一收紙轉軸。皮帶輪可轉動地設置於支架上。連接件設置於皮帶輪之一側。傳動件可轉動地設置於皮帶輪與連接件之間。摩擦件選擇性地設置於皮帶輪與傳動件之間或設置於傳動件與連接件之間。第一彈性件選擇性地設置於傳動件與連接件之間或設置於皮帶輪與傳動件之間。收紙轉軸之一第一端可轉動地設置於支架上，且收紙轉軸之一第二端連接於連接件，其中第一端與第二端相對。傳動皮帶連接於供紙滾軸與皮帶輪。 According to one embodiment, the printer of the present invention includes a paper feed roller, a drive unit, a bracket, a delivery mechanism, and a drive belt. The drive unit is connected to the paper feed roller. The delivery mechanism includes a pulley, a connecting member, a transmission member, a friction member, a first elastic member and a delivery shaft. The pulley is rotatably disposed on the bracket. The connector is disposed on one side of the pulley. The transmission member is rotatably disposed between the pulley and the connecting member. The friction member is selectively disposed between the pulley and the transmission member or between the transmission member and the connecting member. The first elastic member is selectively disposed between the transmission member and the connecting member or between the pulley and the transmission member. One of the first ends of the delivery shaft is rotatably disposed on the bracket, and one of the second ends of the delivery shaft is coupled to the connector, wherein the first end is opposite to the second end. The drive belt is connected to the paper feed roller and the pulley.

較佳地，摩擦件設置於皮帶輪與傳動件之間，第一彈性件設置於傳動件與連接件之間，且第一彈性件之二端分別抵接於傳動件與連接件。 Preferably, the friction member is disposed between the pulley and the transmission member, and the first elastic member is disposed between the transmission member and the connecting member, and the two ends of the first elastic member respectively abut the transmission member and the connecting member.

較佳地，收紙轉軸另包含一固定件，設置於傳動件與連接件之間，摩擦件設置於傳動件與固定件之間，第一彈性件設置於皮帶輪與傳動件之間，且第一彈性件之二端分別抵接於皮帶輪與傳動件。 Preferably, the delivery shaft further comprises a fixing member disposed between the transmission member and the connecting member, the friction member is disposed between the transmission member and the fixing member, and the first elastic member is disposed between the pulley and the transmission member, and The two ends of an elastic member abut against the pulley and the transmission member, respectively.

較佳地，摩擦件設置於傳動件與連接件之間，第一彈性件設置於皮帶輪與傳動件之間，且第一彈性件之二端分別抵接於皮帶輪與傳動件。 Preferably, the friction member is disposed between the transmission member and the connecting member, the first elastic member is disposed between the pulley and the transmission member, and the two ends of the first elastic member respectively abut the pulley and the transmission member.

綜上所述，在本發明之印表機組裝完成後，第一彈性件即會透過傳動件提供正壓力給摩擦件。當驅動裝置驅動供紙滾軸轉動時，供紙滾軸會帶動傳動皮帶轉動，進而帶動皮帶輪轉動。在皮帶輪轉動的過程中，接觸摩擦件的元件(例如，皮帶輪、傳動件、固定件及/或連接件)與摩擦件之間即會產生轉動摩擦，來帶動收紙轉軸轉動，進而將收紙轉軸與供紙滾軸之線速度調整為一致。藉此，在供紙滾軸帶動紙捲轉動來進行列印時，收紙轉軸即可同時將已列印的紙張回捲。 In summary, after the assembly of the printer of the present invention is completed, the first elastic member provides positive pressure to the friction member through the transmission member. When the driving device drives the paper feed roller to rotate, the paper feed roller will drive the drive belt to rotate, thereby driving the pulley to rotate. During the rotation of the pulley, the frictional friction between the components contacting the friction member (for example, the pulley, the transmission member, the fixing member and/or the connecting member) and the friction member will drive the delivery shaft to rotate, thereby receiving the paper. The speed of the shaft and the paper feed roller are adjusted to match. Thereby, when the paper feed roller drives the paper roll to rotate for printing, the paper take-up reel can simultaneously rewind the printed paper.

In this embodiment, the printer 1 can be a thermal-sensing printer, the printing module 20 can be a thermal-sensing printing module, and the paper roll 3 can be a heat-sensitive paper roll, but not Limited. 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. The paper feed roller 12, the driving device 14, the delivery mechanism 16, the transmission belt 18 and the printing module 20 are all disposed in the receiving groove 100 of the housing 10. In a practical application, the printer 1 can include a cover (not shown) that is removably or rotatably disposed on the housing 10 to cover the components disposed in the receiving slot 100.

驅動裝置14連接於供紙滾軸12，用以驅動供紙滾軸12轉動，進而帶動紙捲3轉動。列印模組20相對供紙滾軸12設置，當供紙滾軸12帶動紙捲3轉動時，列印模組20即可對紙捲3的紙張進行列印。於實際應用中，驅動裝置14可由馬達、齒輪組等組成。 The driving device 14 is connected to the paper feed roller 12 for driving the paper feed roller 12 to rotate, thereby driving the paper roll 3 to rotate. The printing module 20 is disposed relative to the paper feed roller 12, and when the paper feed roller 12 drives the paper roll 3 to rotate, the printing module 20 can print the paper of the paper roll 3. In practical applications, the drive unit 14 can be composed of a motor, a gear set, and the like.

如第3圖至第5圖所示，收紙機構16包含一支架160、一皮帶輪162、一連接件164、一傳動件166、一摩擦件168、一第一彈性件170以及一收紙轉軸172。皮帶輪162可轉動地設置於支架160上。連接件164設置於皮帶輪162之一側。傳動件166可轉動地設置於皮帶輪162與連接件164之間。摩擦件168設置於皮帶輪162與傳動件166之間。第一彈性件170設置於傳動件166與連接件164之間，且第一彈性件170之二端分別抵接於傳動件166與連接件164。於此實施例中，第一彈性件170可為彈簧或其它彈性體。收紙轉軸172之一第一端1720可轉動地設置於支架160上，且收紙轉軸172之一第二端1722連接於連接件164，其中第一端1720與第二端1722相對。傳動皮帶18連接於供紙滾軸12與皮帶輪162。 As shown in FIG. 3 to FIG. 5 , the delivery mechanism 16 includes a bracket 160 , a pulley 162 , a connecting member 164 , a transmission member 166 , a friction member 168 , a first elastic member 170 , and A delivery shaft 172. The pulley 162 is rotatably disposed on the bracket 160. The connecting member 164 is disposed on one side of the pulley 162. The transmission member 166 is rotatably disposed between the pulley 162 and the connecting member 164. The friction member 168 is disposed between the pulley 162 and the transmission member 166. The first elastic member 170 is disposed between the transmission member 166 and the connecting member 164 , and the two ends of the first elastic member 170 abut against the transmission member 166 and the connecting member 164 . In this embodiment, the first elastic member 170 can be a spring or other elastic body. A first end 1720 of the delivery reel 172 is rotatably disposed on the bracket 160, and a second end 1722 of the delivery reel 172 is coupled to the connector 164, wherein the first end 1720 is opposite the second end 1722. The drive belt 18 is coupled to the paper feed roller 12 and the pulley 162.

組裝收紙機構16時，可先將皮帶輪162一端置入支架160一側的孔洞1600，再將摩擦件168置入皮帶輪162中。接著，將傳動件166一端的突柱1660穿過摩擦件168與皮帶輪162上的孔洞。接著，於皮帶輪162一側設置墊片174，再以固定件(例如，螺絲)176鎖固於傳動件166之突柱1660上。接著，將第一彈性件170與連接件164依序套設於傳動件166另一端的突柱1662上，再以另一固定件(例如，螺絲)178鎖固於傳動件166之突柱1662上。接著，可以收紙轉軸172之第二端1722將連接件164朝第3圖之箭頭A1的方向壓迫，而壓縮第一彈性件170，再將收紙轉軸172之第一端1720上的突柱1724對準支架160另一側的孔洞1602***。此時，被壓縮的第一彈性件170即會提供彈性力將連接件164與收紙轉軸172朝第3圖之箭頭A2的方向推擠，進而完成收紙機構16的組裝。收紙機構16組裝完成後，第一彈性件170會透過傳動件166提供正壓力給摩擦件168，以使摩擦件168分別與傳動件166及皮帶輪162緊密接觸。 When the delivery mechanism 16 is assembled, one end of the pulley 162 can be placed into the hole 1600 on the side of the bracket 160, and the friction member 168 can be placed in the pulley 162. Next, the stud 1660 at one end of the transmission member 166 is passed through the friction member 168 and the hole in the pulley 162. Next, a spacer 174 is disposed on one side of the pulley 162, and then locked to the protrusion 1660 of the transmission member 166 by a fixing member (for example, a screw) 176. Then, the first elastic member 170 and the connecting member 164 are sequentially sleeved on the protruding post 1662 at the other end of the transmission member 166, and then locked to the protruding post 1662 of the transmission member 166 by another fixing member (for example, a screw) 178. on. Then, the second end 1722 of the take-up reel 172 can press the connecting member 164 toward the arrow A1 of FIG. 3 to compress the first elastic member 170, and then the stud on the first end 1720 of the take-up reel 172. The 1724 is inserted into the hole 1602 on the other side of the bracket 160. At this time, the compressed first elastic member 170 provides an elastic force to push the connecting member 164 and the delivery shaft 172 in the direction of the arrow A2 of FIG. 3, thereby completing the assembly of the delivery mechanism 16. After the delivery mechanism 16 is assembled, the first elastic member 170 provides a positive pressure to the friction member 168 through the transmission member 166, so that the friction member 168 is in close contact with the transmission member 166 and the pulley 162, respectively.

於此實施例中，連接件164之一端可具有N個第一凸肋1640，且收紙轉軸172之第二端1722可具有M個第二凸肋1726，其中N與M皆為正整數。當N大於1時，N個第一凸肋1640呈放射狀對稱排列。當M大於1時，M個第二凸肋1726呈放射狀對稱排列。N個第一凸肋1640與M個第二凸肋1726可相互嚙合，使得收紙轉軸172之第二端1722連接於連接件 164。較佳地，N個第一凸肋1640與M個第二凸肋1726以鬆配合的方式相互嚙合，以方便組裝連接件164與收紙轉軸172。 In this embodiment, one end of the connecting member 164 may have N first ribs 1640, and the second end 1722 of the take-up reel 172 may have M second ribs 1726, wherein N and M are both positive integers. When N is greater than 1, the N first ribs 1640 are radially symmetrically arranged. When M is greater than 1, the M second ribs 1726 are radially symmetrically arranged. The N first ribs 1640 and the M second ribs 1726 can be engaged with each other such that the second end 1722 of the delivery shaft 172 is connected to the connecting member 164. Preferably, the N first ribs 1640 and the M second ribs 1726 are in meshing engagement with each other to facilitate assembly of the connecting member 164 and the take-up reel 172.

如第4圖所示，連接件164之一端可具有三個第一凸肋1640(亦即，N=3)，且三個第一凸肋1640呈放射狀對稱排列。如第5圖所示，收紙轉軸172之第二端1722可具有三個第二凸肋1726(亦即，M=3)，且三個第二凸肋1726呈放射狀對稱排列。需說明的是，第一凸肋1640與第二凸肋1726的數量與排列方式可根據實際應用來決定，不以第4圖與第5圖所繪示之實施例為限。於此實施例中，第一凸肋1640的寬度小於兩相鄰第二凸肋1726之間的間隙，且第二凸肋1726的寬度也小於兩相鄰第一凸肋1640之間的間隙，以使第一凸肋1640與第二凸肋1726以鬆配合的方式相互嚙合。藉此，不需精準地對位即可輕易地將連接件164組裝於收紙轉軸172之第二端1722。於實際應用中，只要有至少一個第一凸肋1640與至少一個第二凸肋1726以鬆配合的方式相互嚙合，即可達到方便組裝連接件164與收紙轉軸172的目的。 As shown in FIG. 4, one end of the connecting member 164 may have three first ribs 1640 (i.e., N = 3), and the three first ribs 1640 are radially symmetrically arranged. As shown in Fig. 5, the second end 1722 of the delivery shaft 172 may have three second ribs 1726 (i.e., M = 3), and the three second ribs 1726 are radially symmetrically arranged. It should be noted that the number and arrangement of the first ribs 1640 and the second ribs 1726 can be determined according to practical applications, and are not limited to the embodiments illustrated in FIGS. 4 and 5. In this embodiment, the width of the first rib 1640 is smaller than the gap between the two adjacent second ribs 1726, and the width of the second rib 1726 is also smaller than the gap between the two adjacent first ribs 1640. The first rib 1640 and the second rib 1726 are engaged with each other in a loose fit. Thereby, the connector 164 can be easily assembled to the second end 1722 of the delivery shaft 172 without precise alignment. In practical applications, as long as at least one first rib 1640 and at least one second rib 1726 are engaged with each other in a loose fit, the purpose of assembling the connecting member 164 and the take-up reel 172 can be achieved.

當驅動裝置14驅動供紙滾軸12轉動時，供紙滾軸12會帶動傳動皮帶18轉動，進而帶動皮帶輪162轉動。在皮帶輪162轉動的過程中，皮帶輪162與摩擦件168之間以及傳動件166與摩擦件168之間即會產生轉動摩擦，來帶動收紙轉軸172轉動，進而將收紙轉軸172與供紙滾軸12之線速度調整為一致。藉此，在供紙滾軸12帶動紙捲3轉動來進行列印時，收紙轉軸172即可同時將已列印的紙張回捲。 When the driving device 14 drives the paper feed roller 12 to rotate, the paper feed roller 12 drives the transmission belt 18 to rotate, thereby driving the pulley 162 to rotate. During the rotation of the pulley 162, a rotational friction is generated between the pulley 162 and the friction member 168 and between the transmission member 166 and the friction member 168 to drive the delivery shaft 172 to rotate, thereby the delivery shaft 172 and the paper feed roller. The linear velocity of the shaft 12 is adjusted to be uniform. Thereby, when the paper feed roller 12 rotates the paper roll 3 to perform printing, the paper take-up reel 172 can simultaneously rewind the printed paper.

組裝收紙機構16'時，可先將皮帶輪162一端置入支架160一側的孔洞1600，將摩擦件168、傳動件166與第一彈性件170依序套設於固定件180之突柱1800上，再將固定件180之突柱1800連同摩擦件168、傳動件166與第一彈性件170置入皮帶輪162中。接著，於皮帶輪162一側設置墊片174，再以固定件(例如，螺絲)176鎖固於固定件180之突柱1800上。此時，第一彈性件170處於壓縮狀態，因此第一彈性件170會透過傳動件166提供正壓力給摩擦件168，以使摩擦件168分別與傳動件166及固定件180緊密接觸。接著，將第二彈性件182與連接件164依序套設於固定件180另一端的突柱1802上，再以另一固定件(例如，螺絲)178鎖固於固定件180之突柱1802上。接著，可以收紙轉軸172之第二端1722將連接件164朝第7圖之箭頭A1的方向壓迫，而壓縮第二彈性件182，再將收紙轉軸172之第一端1720上的突柱1724對準支架160另一側的孔洞1602***。此時，被壓縮的第二彈性件182即會提供彈性力將連接件164與收紙轉軸172朝第3圖之箭頭A2的方向推擠，進而完成收紙機構16'的組裝。 When the delivery mechanism 16' is assembled, one end of the pulley 162 can be first placed into the hole 1600 on the side of the bracket 160, and the friction member 168, the transmission member 166 and the first elastic member 170 are sequentially sleeved on the protrusion 1800 of the fixing member 180. Then, the stud 1800 of the fixing member 180 is further placed into the pulley 162 together with the friction member 168, the transmission member 166 and the first elastic member 170. Next, a spacer 174 is disposed on one side of the pulley 162, and then fixed to the protrusion 1800 of the fixing member 180 by a fixing member (for example, a screw) 176. At this time, the first elastic member 170 is in a compressed state, so that the first elastic member 170 transmits a positive pressure to the friction member 168 through the transmission member 166, so that the friction member 168 is in close contact with the transmission member 166 and the fixing member 180, respectively. Then, the second elastic member 182 and the connecting member 164 are sequentially sleeved on the stud 1802 at the other end of the fixing member 180, and then locked to the stud 1802 of the fixing member 180 by another fixing member (for example, a screw) 178. on.

第1圖與第2圖中的收紙機構16可以第6圖至第9圖中的收紙機構16'替換。當驅動裝置14驅動供紙滾軸12轉動時，供紙滾軸12會帶動傳動皮帶18轉動，進而帶動皮帶輪162轉動。在皮帶輪162轉動的過程中，傳動件166與摩擦件168之間以及固定件180與摩擦件168之間即會產生轉動摩擦，來帶動收紙轉軸172轉動，進而將收紙轉軸172與供紙滾軸12之線速度調整為一致。藉此，在供紙滾軸12帶動紙捲3轉動來進行列印時，收紙轉軸172即可同時將已列印的紙張回捲。 The delivery mechanism 16 of Figs. 1 and 2 can be replaced by the delivery mechanism 16' of Figs. 6 to 9. When the driving device 14 drives the paper feed roller 12 to rotate, the paper feed roller 12 drives the transmission belt 18 to rotate, thereby driving the pulley 162 to rotate. During the rotation of the pulley 162, rotational friction is generated between the transmission member 166 and the friction member 168 and between the fixing member 180 and the friction member 168 to drive the delivery shaft 172 to rotate, thereby the delivery shaft 172 and the paper feed. The linear speed of the roller 12 is adjusted to be the same. Thereby, when the paper feed roller 12 rotates the paper roll 3 to perform printing, the paper take-up reel 172 can simultaneously rewind the printed paper.
