  The holding part A6 is not limited to the form in which the chain members A7 and A8 are guided so as to slide with respect to the contact part A61. For example, the chain members A7 and A8 may be supported and guided by a sprocket. Moreover, not only a slidable form but a fixed position fixed form may be sufficient.

  The conveying member A9 is made of a flexible sheet material, and is fixed so as to be positioned on the inner peripheral side of the chain members A7 and A8.

  According to the return conveyor 9 having such a configuration, the conveying surface portion A1 is set in a range extending from the sprocket A4 to the lower portion of the reversing surface portion 55, and the facing conveying portion A2 secures the passage 90 of the molding material around the reversing surface portion 55. Set to That is, the material to be molded that has been dropped from the receiving unit 70 by the transport body 71 by performing the operation of transporting the material to be molded to the side of the transport conveyor 5 along with the operation of transporting the material to be molded to the molding chamber 2 of the transport conveyor 5 The material is received by the conveyance surface portion A1 and conveyed in the direction of the conveyance conveyor 5. When the molding material to be conveyed reaches the facing conveyance section A2, the conveyance projection 53 of the conveyance conveyor 5 scoops up the molding material and returns it to the conveyance surface 50. At this time, the facing conveyance unit A2 operates in the same direction as the reversal surface unit 55, and the molding material is returned to the conveyance surface 50 so that the conveyance unit A2 assists the scooping of the molding material by the conveyance projection 53. It becomes a state. Therefore, the molding material transported to the facing transport section A2 can be returned to the transport surface 50 efficiently and reliably.

  According to the roll baler 1 of the present embodiment, the molding material that spills from the roll bale A is conveyed to the storage space 72 when the roll bale A molded from the supply of the molding material is wrapped, as in the first embodiment. The conveyed molding material can be supplied to the molding chamber 2 again. Further, since the material to be molded can be efficiently and reliably returned to the transport surface 50 by the transport conveyor 5 and the return conveyor 9, the remaining amount of the material to be molded that has been transported from the receiving unit 70 on the return conveyor 9 Can be greatly reduced. Therefore, the inside of the roll baler 1 after the work can be easily cleaned, and the amount of the material to be formed can be greatly reduced.

  The return conveyor 9 may perform an operation reverse to the operation of returning the molding material to the transport surface 50 and discharge the molding material remaining on the return conveyor 9 from the end on the sprocket A4 side. In this case, the molding material remaining on the transport surface may be returned to the return conveyor 9 by causing the transport conveyor 5 to reverse the transport operation.

  It is preferable that the speed of the conveying operation of the molding material of the return conveyor 9 is the same as the speed of the conveying operation of the conveying conveyor 5. For example, the same motor (not shown) can be driven with respect to the transport conveyor 5 and the return conveyor 9 via a rotation transmission device (not shown) such as a chain or a belt. A configuration in which the number of rotations is distributed and transmitted is given. As another configuration, a motor having the same output is provided on each of the return conveyor 9 side and the transport conveyor 5 side (not shown), and the power source (not shown) of this motor is the same, thereby returning the conveyor. The structure which makes the conveyance operation of 9 and the conveyance operation of the conveyance conveyor 5 the same speed is mentioned.

  The speed of the transport operation of the return conveyor 9 and the speed of the transport operation of the transport conveyor 5 are as described above as long as the molding material transported to the facing transport section A2 can be returned to the transport surface 50 efficiently and reliably. It is not limited to the same speed.

  Although the roll baler 1 of this embodiment has illustrated the form which conveys the molding material which spills through the receiving part 70 to the return conveyor 9, it can also be made into the form which does not comprise the receiving part 70. FIG. In the roll baler 1 of this form, by extending the conveyance surface portion A1 of the return conveyor 9 to the downstream end portion in the conveyance direction of the conveyance conveyor 6, the molding material spilling from the conveyance conveyor 6 side can be conveyed in the conveyance conveyor direction.
