Description
本發明關於一種帶鋸機,尤指一種可自動調整鋸切速度之帶鋸機。The invention relates to a band saw machine, in particular to a band saw machine capable of automatically adjusting the sawing speed.
一般來說,使用者在操作帶鋸機時需要依照工件的材料特性調整鋸帶的鋸切速度,像是質地較軟之材料(例如木材)可以用較快的速度進行鋸切,但是質地較硬之材料(例如金屬)則是要以較慢的速度進行鋸切,如此不但可以避免鋸帶斷裂,也可以讓鋸帶具有較佳的鋸切效率。Generally speaking, when the user operates the band saw, the sawing speed of the saw band needs to be adjusted according to the material properties of the workpiece. For example, a soft material (for example, wood) can be sawed at a faster speed, but the texture is better. Hard materials (such as metal) are sawed at a slower speed, which not only avoids the breakage of the saw band, but also allows the saw band to have better sawing efficiency.
中華民國公告第M338123號專利案是利用變頻器來調整馬達的轉速而間接調整鋸帶的速度,並同時透過螢幕顯示馬達的電源頻率或轉速,但是變頻器所顯示的數據並非鋸帶實際的鋸切速度,對使用者來說在數據判讀上可能會有誤差的存在,因此往往無法將鋸帶調整到最適當的速度,進而連帶影響鋸帶的鋸切效率及使用壽命。The Republic of China Announcement No. M338123 patent uses the frequency converter to adjust the speed of the motor to indirectly adjust the speed of the saw belt, and simultaneously displays the power frequency or speed of the motor through the screen, but the data displayed by the inverter is not the saw with the actual saw. The cutting speed may cause errors in the data interpretation for the user, so it is often impossible to adjust the saw band to the most appropriate speed, which in turn affects the sawing efficiency and service life of the saw band.
本發明之主要目的在於提供一種帶鋸機,其能自動調整鋸帶的鋸切速度,以提升鋸切效率及使用壽命。The main object of the present invention is to provide a band saw machine capable of automatically adjusting the sawing speed of the saw band to improve the sawing efficiency and service life.

The motor is disposed on the machine and has a drive shaft; the initiative The wheel is rotatably disposed on the machine and coupled to the drive shaft of the motor, and is rotatable by the motor; the driven wheel is rotatably disposed on the machine table and opposite to the drive wheel; the saw band is disposed around the wheel a driving wheel and the driven wheel for cutting a workpiece; the saw belt adjusting seat is disposed between the machine and the driving wheel and the driven wheel, and is pressed against the saw band; the vibration sensor is disposed at the The surface of the saw strap adjustment seat is configured to sense a vibration generated by the saw strap adjustment seat during sawing to send a sensing signal; the control system is electrically connected to the motor and the vibration sensor for receiving the The sensing signal of the vibration sensor is vibrated, and the power output of the driving wheel to the driving wheel is controlled according to the sensing signal.

各震動感測器72在本實施例中為一加速規且固定於鋸帶調整座70之表面,用以感測鋸帶調整座70於鋸切時所產生的震動而發送一感測訊號。在此需要補充說明的是,震動感測器72只要配合鋸帶調整座70而設置至少一組即可。In this embodiment, each of the vibration sensors 72 is an acceleration gauge and is fixed to the surface of the saw blade adjustment seat 70 for sensing the vibration generated by the saw blade adjustment seat 70 during sawing and transmitting a sensing signal. It should be additionally noted that the vibration sensor 72 may be provided with at least one set in conjunction with the saw band adjustment seat 70.
控制系統80設於機台20且電性連接馬達30及兩震動感測器72,用以接收各震動感測器72的感測訊號而控制馬達30的轉速。The control system 80 is disposed on the machine 20 and electrically connected to the motor 30 and the two shock sensors 72 for receiving the sensing signals of the vibration sensors 72 to control the rotation speed of the motor 30.
另外,為了將鋸帶60調整到適當的鬆緊度,本發明之帶鋸機10更提供一張力調整裝置90,如第2圖所示,張力調整裝置90具有一滑塊91、一油壓缸92、一儲油槽93、一擋塊94及一彈性件95。油壓缸92具有一缸體922及一活 塞桿924,缸體922固定於機台20之從動輪座24的背面,活塞桿924之一端設於缸體922內,活塞桿924之另一端在伸長時推抵滑塊91,使從動輪50能透過滑塊91沿著長槽26相對主動輪40移動,用以撐緊或鬆放鋸帶60;儲油槽93固定於機台20之背面,用以儲存液壓油,並且藉由一輸油管96連接油壓缸92之缸體922,使液壓油能夠輸送至油壓缸92之缸體922內,迫使油壓缸92之活塞桿924伸長;擋塊94固定於機台20的背面;彈性件95設於滑塊91及擋塊94之間,使彈性件95能夠透過推動滑塊91而將從動輪50朝油壓缸72的方向推動,用以方便鬆放鋸帶60。In addition, in order to adjust the saw band 60 to an appropriate degree of tightness, the band saw machine 10 of the present invention further provides a force adjusting device 90. As shown in FIG. 2, the tension adjusting device 90 has a slider 91 and a hydraulic cylinder. 92. An oil storage tank 93, a stopper 94 and an elastic member 95. The hydraulic cylinder 92 has a cylinder 922 and a live The plug rod 924 is fixed to the back surface of the driven wheel base 24 of the machine table 20. One end of the piston rod 924 is disposed in the cylinder block 922, and the other end of the piston rod 924 is pushed against the slider 91 when extended, so that the driven wheel 50 can be moved relative to the driving wheel 40 along the long slot 26 through the slider 91 for supporting or loosening the saw band 60; the oil storage groove 93 is fixed on the back of the machine table 20 for storing hydraulic oil, and by a fuel pipe 96 is connected to the cylinder 922 of the hydraulic cylinder 92 to enable hydraulic oil to be delivered into the cylinder 922 of the hydraulic cylinder 92, forcing the piston rod 924 of the hydraulic cylinder 92 to extend; the stopper 94 is fixed to the back of the machine 20; The member 95 is disposed between the slider 91 and the stopper 94, so that the elastic member 95 can be pushed by the pusher pulley 91 and the driven wheel 50 in the direction of the hydraulic cylinder 72 for facilitating the loosening of the saw band 60.
經由上述結構可知,當主動輪40受馬達30之驅動開始轉動時會同步牽引鋸帶60,接著受主動輪40牽引之鋸帶60會再帶動從動輪50同步轉動,使得鋸帶60便會繞著主動輪40及從動輪50持續轉動,並且在各鋸帶調整座70的導引之下穩定地對工件進行鋸切。在鋸切工件的過程中,鋸帶60會根據不同的工件材料而將不同程度的震動傳遞至各鋸帶調整座70,此時的震動感測器72會感測鋸帶調整座70所受到的震動而分別發送一感測訊號至控制系統80,若震動程度較小,控制系統80會增加馬達30之轉速,使鋸帶60加快鋸切速度,若震動程度較大,控制系統80則是會降低馬達30之轉速,使鋸帶60減慢鋸切速度。換言之,控制系統80會根據所接受到的感測訊號調整馬達30對主動輪40的動力輸出,用以即時調整鋸帶60的鋸切速度而維持於鋸切時所需要的力量。It can be seen from the above structure that when the driving wheel 40 is driven to rotate by the motor 30, the traction saw belt 60 is synchronously, and then the saw belt 60 pulled by the driving wheel 40 will drive the driven wheel 50 to rotate synchronously, so that the sawing belt 60 will be wound. The driving wheel 40 and the driven wheel 50 are continuously rotated, and the workpiece is stably sawed under the guidance of each of the saw band adjusting seats 70. During the sawing of the workpiece, the saw band 60 transmits different degrees of vibration to each of the saw band adjustment seats 70 according to different workpiece materials. At this time, the vibration sensor 72 senses the saw band adjustment seat 70. The vibration signal sends a sensing signal to the control system 80 respectively. If the vibration level is small, the control system 80 increases the rotation speed of the motor 30, so that the saw belt 60 speeds up the sawing speed. If the vibration level is large, the control system 80 is The speed of the motor 30 is reduced, causing the saw band 60 to slow down the sawing speed. In other words, the control system 80 adjusts the power output of the motor 30 to the drive wheel 40 based on the received sense signal to instantly adjust the sawing speed of the saw band 60 to maintain the force required for sawing.
綜上所陳,本發明之帶鋸機10利用震動感測器72即時監控鋸帶60於鋸切時所產生的震動,並將感測到的數值回饋至控制系統80,使控制系統80自動調整馬達30對主動輪50的動力輸出,如此便能達到提升鋸帶60的鋸切精度及使用壽命,以達到本發明之目的。In summary, the band saw machine 10 of the present invention uses the vibration sensor 72 to instantly monitor the vibration generated by the saw band 60 during sawing, and feeds the sensed value back to the control system 80, so that the control system 80 automatically The power output of the motor 30 to the drive wheel 50 is adjusted, so that the sawing accuracy and service life of the saw band 60 can be improved to achieve the object of the present invention.
