の突出位置より上流側へ位置ずれして停止する。<Problem to be solved by the invention> However, in the case of the former case, the body wrapping device of such a conventional packaging machine does not fold the transferred contents against the preceding contents and fold the rear end surface of the contents on both sides. In order to position the protruding position of the guide, when the transferred content hits the preceding content, the preceding content moves downstream due to its inertia, and the rear end surface of the transferred content folds in both sides. When the guide shifts downstream from the protruding position and stops, or when the transported contents collide with the preceding contents, the preceding contents are compressed and deformed, causing the compression of these preceding contents. When the deformation is elastically restored, the rear end surface of the transported contents shifts upstream from the protruding positions of both folding guides and stops.

題がある。 In the latter case, although the above-mentioned problem does not occur, the turret is provided with multiple pockets into which the contents fit, making the turret very large and complicated in structure, making the entire device large. There is a problem that not only is the cost increasing, but also the cost is increasing.

ガイドの突出位置を正確に位置決めできる。 After the forward end of the transferred contents hits the wrapping paper, both of them are inserted into the through hole through one opening of the stopped half-turn turret, so that the forward end of the contents hits the stopper block. At the same time, the wrapping paper is wrapped around the body in a U-shape, and after this stopper block moves to the furthest downstream side and the movement of the contents stops, a pair of folding guides are moved to the downstream side. Both ends of the wrapping paper are made to protrude and folded in along the rear edge of the contents, and then the semi-turning turret is rotated 180 degrees, and the following contents that are in contact with the wrapping paper are inserted into the through hole from the other opening. By fitting into the through hole, the leading end of the following contents hits the stopper block and is moved downstream, and at the same time, the contents that have been wrapped around the body are pushed out downstream from within this through hole. By sequentially abutting the transferred contents against one stopper, the rear end surface of the contents and the protruding positions of both folding guides can be accurately positioned.

Both ends of the wrapping paper can be reliably folded along the rear edge of the contents without shifting to the downstream or upstream side of the position, and as a result, the wrapping paper can be wrapped tightly around the body and the contents can be folded. Compared to the conventional system in which the turret is provided with a plurality of pockets into which the turrets are inserted, the half-turn turret is smaller and has a simpler structure, making it possible to downsize the entire device and reduce costs.

たことを特徴とする包装機の胴巻き装置。 A wrapping paper supply path is arranged perpendicular to the transfer path for transporting the box-shaped contents, and the tip of the contents transferred along this transfer path in the traveling direction is brought into contact with the supplied wrapping paper. A pair of folding guides are placed on the downstream side of the wrapping paper supply path in the direction of transport of the contents, while wrapping the wrapping paper in the shape of a . In a body wrapping device of a folding packaging machine, the pair of folding guides are arranged so as to be movable in and out in a direction perpendicular to the direction of transport of the contents, and a semi-turning turret is arranged intermittently at 180 degrees downstream from these folding guides in the direction of transport. A through hole through which the wrapping paper and contents enter and exit the semi-turning turret is provided in line with the transfer path, and the wrapping paper and contents are transferred from either opening of the through hole. By inserting the object, the body is wrapped in a U-shape and the body is held in a U-shaped state, and a stopper block is disposed within the through hole so as to be able to reciprocate over a predetermined section between both openings. The length of movement was set to be approximately the same as the dimension of the contents in the direction of transfer, and the distance from the stopper block to both folding guides when moved to the most downstream side was set to be the same as the dimension of the contents in the direction of transfer. Features: A wrapping device for packaging machines.
