| 摘要 | A machine for producing circular products such as bottoms and lids of casks comprising a machine base, a blank feeding station, a blank sawing station, a blank chamfering station and a blank positioning station provided on said base in a circumferentially spaced relationship, a vertical main drive shaft rotatably mounted in said base, blank support means fixedly mounted on said drive shaft and having a plurality of spaced blank support discs, blank holding-down means fixedly mounted on said drive shaft and having a plurality of arms each having a downwardly extending shaft on which a blank holding-down member is journalled in opposition to the associated one of said support discs to hold a blank therebetween. | ||||||
| 权利要求 | 1. A machine for producing circular products comprising a base having a blank feeding station, a blank sawing station, a blank chamfering station and a blank positioning station which are positioned on said base in a circumferentially spaced relationship, a vertically extending main drive shaft intermittently rotatably mounted on said base, blank support means fixedly mounted on said main drive shaft and having a plurality of equally spaced support discs, a blank holding-down means fixedly mounted on said main drive shaft above said blank support means and having a plurality of spaced blank holding-down members in opposition to said support discs, respectively and adapted to hold blanks in cooperation with their respective associated ones of said support discs, said holding-down members and support discs being adapted to be in succession disposed in said feeding, sawing, chamfering and positioning stations, vertically movable rotation transmission means positioned in each of said sawing and chamfering stations for engaging each of said blank support discs to transfer rotation to the support disc when the support disc is disposed in each of the sawing and chamfering stations, a rotational band saw positioned in said sawing station for sawing engagement with a blank held by the holding-down member and associated support disc when the member and disc are disposed in the sawing station, a rotational chamfering cutter positioned in said chamfering position for chamfering engagement with the sawn blank from said sawing station when the holdingdown member and support disc holding the sawn blank therebetween are disposed in the chamfering station and detent means positioned in said positioning station to engage the holding-down and support disc in said positioning station so as to stop the movement of said holding-down and support discs disposed in the feeding, sawing, chamfering and positioning to thereby allow said band saw and cutter to perform their sawing and chamfering operations on the blanks positioned in these stations. 2. The machine as set forth in claim 1, in which said blank support means comprises a cross-shaped support assembly fixedly mounted on said main drive shaft and having four said support discs extending from the center of the assembly. 3. The machine as set forth in claim 1, in which said blank holding-down means comprises a cross-shaped assembly fixedly mounted on said main drive shaft and having four arms extending radially from the center of the assembly, each of said arms rotatably supporting one of said blank holding-down members. 4. The machine as set forth in claim 3, in which each of said arms has a hollow shaft depending therefrom and said blank holding-down member is rotatably supported on said hollow shaft. 5. The machine as set forth in claim 1, in which said rotation transmission means comprises a vertically reciprocal and rotational shaft positioned below each of said sawing and chamfering stations for engaging and disengaging from said blank support disc when the arm is positioned in each of the sawing and chaMfering stations. 6. The machine as set forth in claim 1, in which said detent means comprises a vertically movable detent positioned in said positioning station and a detent hole in the shaft of each of said support discs. 7. The machine as set forth in claim 1, in which an optical detector is provided in said blank feeding station for detecting the center of a blank disposed on the blank support disc positioned in the feeding station. 8. The machine as set forth in claim 1, further including means for adjusting the tension of said band saw. |
