The sending direction of the packing material is a direction orthogonal to the width direction of the packing material, and the packing material sent from the sending device is a direction toward the packing material supply port of the molding chamber.

  Hereinafter, a roll baler according to an embodiment of the present invention will be described with reference to the drawings. The packing material described below is a net. In the following description, the net transmission direction side is assumed to be downward. Each embodiment described below does not limit the present invention.

  FIG.1 and FIG.2 is schematic which shows the structure of 1 A of roll balers of 1st Embodiment. The roll baler 1A includes a forming chamber 2 for forming a cylindrical roll bale A by compressing a material to be formed (not shown) that is shredded, and the roll bale A formed in the forming chamber 2 in the forming chamber 2. A delivery device 3 that sends out the net B to be packed, a guide portion 4 that guides the net B that is sent out from the delivery device 3 to the packing material supply port 20 in the molding chamber 2, and a guide portion 4 of the net B that is in the middle of delivery. The nozzle 5 which injects gas to the net | network B is provided.

  The molding chamber 2 includes a fixed-side half 21 (left half in FIG. 1) partitioned on the delivery device 3 side and a movable-side half 22 partitioned to close the open side of the fixed-side half 21. (The right half in FIG. 1) and a molding device 23 in which a large number of rollers 230 arranged on the fixed half 21 and the movable half 22 are arranged on the circumference.

  In addition, the fixed-side half 21 and the movable-side half 22 are shown by illustrating reverse hatching in FIG.

  The packaging material supply port 20 is opened upward in the direction in which the net B sent in the vertical direction can be inserted above the fixed-side half 21. In addition, below the fixed-side half portion 21, an insertion port 24 for introducing the molding material conveyed from the conveyance conveyor C into the molding chamber 2 is opened.

  Such a molding chamber 2 can form the cylindrical roll bale A by compressing the material to be molded that has been input from the transport conveyor C through the insertion port 24 into the molding chamber 2 while being rotated by the molding device 23. It is like that.

  In addition, after forming the roll bale A, the packing material supplied to the forming chamber 2 is drawn by the roll bale A rotated by the forming apparatus 23 and wound around the roll bale A to form the roll bale. A can be packed.

  The movable half 22 is rotatably supported in a direction to open and close the open side of the fixed half 21 and is fixed by rotating the movable half 21 in the opening direction after the packing of the roll bail A is completed. By opening the open side of the side half 21, the packed roll bale A can be discharged.

  The width of the net B is wider than the width in the molding chamber 2 (the width of the roll bale A), and when the roll bale A is packed in the molding chamber 2, the width from the entire circumferential surface of the roll bale A to the side surface is increased. It can be packaged over a part of (see FIG. 2).

  The feeding device 3 includes a receiving unit 30 that rotatably receives the roll B1 of the net B, a feeding unit 31 that pulls out the net B and sends it to the molding chamber 2, a cutter 32 that cuts the net B, and a cutting of the cutter 32. A receiving portion 33 with which the cutter 32 abuts during operation is provided. The delivery device 3 is a single assembly in which a receiving part 30, a sending part 31, a cutter 32, and a receiving part 33 are built in a casing 34.

  The width of the sending unit 31, the cutter 32, and the receiving unit 33 is equal to or greater than the width of the net B, and the sending unit 31 pulls out the net B so that the net B is not bent or twisted. The net B can be cut so as not to remain uncut in the entire range in the width direction during the net cutting operation of the cutter 32 after completion of packing.

  In the receiving portion 33, two nozzles 5 are arranged with the injection direction of the injection port 50 facing the packing material supply port 20, and the casing 34 has a packing material that is equal to or greater than the width of the net B. A passage port 341 that faces the supply port 20 is opened, and the guide portion 4 is connected to the passage port 341.

  The guide portion 4 is a frame formed so as to be able to surround the circumference of the net B sent from the passage port 341. In the guide portion 4, a passage outlet 40 facing the packing material supply port 20 at the upper side is opened on the lower side.

  The width of the passage outlet 40 is narrower than the width of the net B and equal to or less than the width of the packaging material supply port 20. The passage outlet 40 is arranged so that the net B to be delivered is not in contact with the packing material supply port 20.

  On both sides of the guide portion 4 on the width side of the net B, the passage outlet 40 squeezes along the width direction of the net B and toward the center portion from the upper end side to the lower end portion 410 of the passage outlet 40. In this way, an inclined portion 41 that is inclined so as to cross obliquely downward toward the center in the width direction of the net B is formed in the drawing with respect to the sending direction of the net B.

  The inclined portion 41 is squeezed from the tip side toward the center in the width direction along the inclination of the inclined portion 41 by contacting both ends in the width direction of the net B inserted into the guide portion 4. However, the passage outlet 40 is allowed to pass through.

  That is, due to the inclined portion 41, the width of the net B when passing through the passage outlet 40 is the same as the width of the passage outlet 40, and the width of the net B sent from the passage outlet 40 is the width of the packing material supply port 20. Since the width is equal to or less than the width, the net B can be inserted into the molding chamber 2 without being hooked on the packing material supply port 20.

  Since the net B inserted into the molding chamber 2 expands in the width direction from the squeezed state when pulled by the rotating roll bale A, it can be packed from the entire peripheral surface of the roll bail A to a part of the side surface. .

  The nozzle 5 provided in the receiving portion 33 passes through the injection direction of the injection port 50 of the nozzle 5 at a portion where the cutter 32 does not abut during the cutting operation and a portion corresponding to the upper end portion of the inclined portion 41. 40 toward the lower end portion 410 on the inclined portion 41 side with respect to the sending direction of the net B, it is arranged so as to be obliquely crossing downward toward the center in the width direction of the net B in the drawing. .

  The injection of gas from the nozzle 5 is performed by the pressure of a pump (not shown) via a hose 51 piped to the nozzle 5.

  Since the net B is a lightweight one knitted using a string or yarn made of synthetic resin material fibers, when the net B is inserted into the guide portion 4, a natural wind, a wind generated during the molding operation of the molding chamber 2 is used. It may be blown up or twisted in the guide portion 4 due to vibration or vibration, and may not be able to perform a feeding operation in the guide portion 4 and may stagnate and become clogged (net B indicated by a virtual line in FIG. 1).

  That is, by jetting gas from the nozzle 5 into the guide portion 4, the net B in the guide portion 4 can be prevented from being blown up or twisted, and the net B can be prevented from being blown up or twisted. Thus, the net B can be normally sent from the packing material supply port 20 into the molding chamber 2 without causing the stagnation and clogging of the net B in the guide portion 4.

  Furthermore, since the injection direction of the injection port 50 of the nozzle 5 is directed to the lower end portion 410 on the inclined portion 41 side of the passage outlet 40, the net B is squeezed toward the central portion in the width direction. The net B can be normally sent out from the packing material supply port 20 into the molding chamber 2 without causing the net B to stagnate and clog in the guide portion 4. .

  The gas injection by the nozzle 5 may be stopped when the net B is drawn by the roll bale A, or the gas injection may be continued during the net B sending operation.

  The injection direction of the injection port 50 of the nozzle 5 may be in a range from the direction orthogonal to the delivery direction of the net B to the width direction and the downward direction parallel to the delivery direction of the net B.
