Launch to introduce with reference to a packing 2 and from of the operation of circulation initial state to unit 1, at the circulation initial state, the blade 7 of conveyer 6 is positioned at station 4, and an arm in the arm 15 is set to first operating position, along path P on the next door of packing 2 and in the upstream of packing 2.

Under this state, packing 2 is in the state of slipping away that is about on the blade 7, and its axis A is parallel to direction B.

In the example shown, the axis A of packing 2 becomes 50 ° of angle β to tilt with respect to direction C, and therefore becomes 40 ° of angle α with respect to level.

Member 14 is synchronous so that arm 15 removes packing 2 at the described state of slipping away that is about to from corresponding blade 7 with conveyer 6.

Along with member 14 rotates around axis E, at the part T of surperficial T ₁, packing 2 is promoted along portion's

section

35,36 by respective arms 15.

Because the design of portion's

section

35,36, along with member 14 rotate around axis E, packing 2 is slowly moved to the discharging position, and is inverted gradually especially will slowly move on the conveyer 8 with face 3 relative also parallel faces in 5 o'clock arriving at a station.

Along with member 14 rotations, slide along the second portion (not shown in Fig. 6) of groove 33 in the cam follower surface of member 50, so that little by little arm 15 is risen to second operating position.

Therefore, cam 18 is little by little revised arm 15 and is packed 2 axis A inclination with respect to pedestal 10 along the rotation of path P so that the bearing of trend of part 102 adapts to respect to member 14, and in this way arm 15 is set for the optimum regime that promotes packing 2.

Therefore, packing 2 arrives at a station 5 along path P along advancing around 90 ° of camber lines of axis A.

When its terminal point 5, arm 15 is set to second operating position by the second portion of groove 33, separates with packing 2, and packing 2 is fed on the conveyer 8 and at this moment along path R.

Along with member 14 continues rotation, by the cam follower surface of the member 50 that slides along the first 34 of groove 33, arm 15 moves to first operating position gradually from second operating position.

By the introduction of preamble, the advantage of unit 1 according to the present invention and method will be apparent.

Especially, 45-55 ° angle beta between direction B and the direction C is offset centnifugal force effectively by the component of the E that parallels to the axis of packing 2 weight.

Therefore,, reduced packing 2 is pressed against centnifugal force on the track 17, thereby prevented packing 2 distortion or prevented that them from throwing away from track 17 with respect to the known solution of in introduction, being introduced.

Especially, the applicant observes, the reducing of centnifugal force allow to get rid of track 17 next doors and track 17 with the axis E opposite side on the maintenance structure.

Therefore, the speed that unit 1 according to the present invention and method allow packing 2 to advance along path P increases, and does not reduce the quality of the packing 2 that supplies to conveyer 8.

The part 102 of arm 15 does not have the edge of maintenance and keeps packing 2 and also therefore more or less freely and cheap on producing along path P counteracting centnifugal force.

Also allow at reverse package 2 in only 90 ° the rotation of axis E at ° angle beta of the 45-55 between direction B and the C.

This has reduced the size and 2 times of advancing along this camber line of packing of camber line to a great extent, and packing 2 is unstable especially along camber line, and therefore having reduced packing 2 blocks and lose the risk that contacts with arm 15.

Because path P is extended along 90 ° or littler camber line, thus unit 1 according to the present invention need be in the unit another bending delivery machine in 1 downstream be parallel to the discharging direction conveying and packaging 2 of wrapping machine.

Yet, under the situation that does not deviate from appended claims institute restricted portion, obviously can make variation to unit 1 according to the present invention and method.

Especially, path P can be around the camber line of axis E extension less than 90 °.
