Feed unit for an automatic saw cutting machine for cutting tubes in double-tube cutting mode

摘要

In a supply unit (10) for an automatic saw cutting machine for cutting tubes (T1, T2) in a double-tube cutting mode, the supply unit (10) is directed forward along a first supply axis (x1). 1 A first pair of motor-driven lower rollers (12a, 12b), which are upstream lower rollers and downstream lower rollers, respectively moving the tube (T1), and a second supply shaft (x2) parallel to the first supply shaft (x1). With respect to the second pair of motor-driven lower rollers 14a and 14b, which are upstream lower rollers and downstream lower rollers, respectively moving the second tube T2 forward along the way, and the first pair of lower rollers 12a, 12b The second tube with respect to a first pair of upper rollers (16a, 16b), which is an upstream upper roller and a downstream upper roller, respectively pressing the first tube (T1), and the second pair of lower rollers (14a, 14b). A second pair of upper rollers (18a, 18b) which are upstream upper rollers and downstream upper rollers respectively pressing (T2), and a plurality of first side rollers (22) supporting the first tube (T1) in the lateral direction. Wow, It includes a plurality of second side rollers 24 supporting the second tube T2 in the lateral direction, and the first pair of lower rollers 12a and 12b and the second pair of lower rollers 14a and 14b ), the upstream rollers 12a, 14a are _{rotatably mounted with respect to the first transverse rotation axis y a} , and the first pair of lower rollers 12a and 12b and the second pair of lower rollers 14a, 14b) downstream of the roller (12b, 14b of) the first transverse axis of rotation (y _a) parallel to the second transverse axis of rotation (y _b) in rotation and can be mounted, wherein the first pair of upper rollers (16a against, 16b) and the upper rollers (16a, 18a) of the upper rollers (18a, 18b) of the second pair is rotatable about a third transverse axis of rotation (y _'a) parallel to the first transverse axis of rotation (y _a) The first pair of upper rollers (16a, 16b) and the second pair of upper rollers (18a, 18b) of the downstream rollers (16b, 18b) are parallel to _{the first transverse axis of rotation (y a)} It is rotatably mounted about the fourth transverse axis of rotation (y' _b ), and each of the upper rollers (16a, 16b, 18a, 18b) is provided with respect to the lower rollers (12a, 12b, 14a, 14b). T1, T2) to be moved toward each of the lower rollers (12a, 12b, 14a, 14b) to clamp, and the first transverse rotation axis (y _a ) is 0 degrees to 60 degrees including the boundary value with respect to the horizontal. It is inclined at an angle and includes a separating member 34 that can alternately move between the seating position and the working position, and at the seating position, passing through the first supply shaft (x1) and the second supply shaft (x2). The whole is arranged under the plane so that it is not interposed between the first tube (T1) and the second tube (T2), and the first tube (T1) and the second tube (T2) come into contact with each other, and the operation In position, to prevent the tubes from coming into contact with each other, the It is disposed between the first tube T1 and the second tube T2.
