Description

  The present invention relates to a roll baler that compresses a material to be molded to form a roll bale.

  A roll baler is known in which a material to be molded supplied to a molding chamber is compressed to form a cylindrical roll bale.

  In the roll baler described in Patent Document 1 below, a large number of rotating rollers are continuously supported between the left and right wall surfaces of the forming chamber so as to be substantially circular in a side view, and are formed in a horizontal direction parallel to the rotating rollers. An opening for supplying material is opened obliquely downward. Also, the opening side is the fixed side half, and the discharge side is the movable side half that opens and closes with respect to the fixed side half. By opening the movable side half, the formed roll bale is discharged. It is supposed to be.

  In this molding chamber, a driving belt is wound around a rotating roller constituting the lower end portion of the opening, and a rotating roller adjacent to the rotating roller and constituting the lower end portion of the fixed side half, and the movable side half A transmission belt is wound around all the rotating rollers. This transmission belt is stretched so that tension is always applied by a tension pulley urged in the discharge direction by a tension spring, and the opening of the movable half is closed in the molding chamber. An auxiliary roller is provided between the drive belt and the transmission belt so as to make rolling contact, and the auxiliary roller transmits the rotation of the transmission belt to the drive belt.

  A roll baler equipped with such a molding chamber is a frictional force generated by the rotation of the drive belt and the transmission belt at the lower boundary between the fixed side end and the movable side end. A roll bale is formed by rotating, and after forming, the movable half is opened to discharge the roll bale. When the diameter of the roll bale is small, the transmission belt during roll bale rotation rotates to separate the fixed half and the movable half, but when the roll bale becomes larger, the transmission belt half It deforms along the inner periphery, and the tension pulley moves to the molding chamber side against the urging force of the tension spring along with this radius.

  According to the roll baler described in Patent Document 1, the material to be molded supplied to the molding chamber is rotationally driven by the friction of the drive belt and the transmission belt on which the tension always acts. Can be molded.

  However, in the roll baler described in Patent Document 1, since only the transmission belt is always subjected to tension, a difference occurs in the frictional force between the drive belt and the transmission belt acting on the material to be molded at the boundary portion. There is a problem that the material to be molded cannot be smoothly rotated and the formation of the central core becomes inefficient. In addition, when the molding material does not rotate smoothly, there is a problem that lamination by winding the molding material around the formed core cannot be performed smoothly.

  This invention makes it an example of a subject to cope with such a problem. That is, the frictional force against the molding material of the two belts that rotate the molding material is balanced, the molding material is smoothly rotated, and the molding material is smoothly rotated, thereby achieving high density. An object of the present invention is to make it possible to efficiently form a central core and to efficiently form a high-density roll bale.

Arranged times A molding belt wound around a roller, and the molding belt is wound around the roller, and the molding belt can be slid so as to be always stretched from before the material to be molded to when the roll bale is molded. And a slide roller supported on the shaft.

  By having such characteristics, the present invention has the following effects. Since both the molding belts are held so as to be always stretched from before the molding material is charged to the end of roll bale molding, the frictional force of the two belts rotating the molding material against the molding material is increased. Since the equilibrium is achieved, the molding material can be smoothly rotated. Then, by smoothly rotating the molding material, it is possible to efficiently form a high-density central core and to efficiently mold a high-density roll bale.

It has become.

  2 to 6 are configuration diagrams of the molding apparatus 22. The forming device 22 is arranged so as to be continuous on a circumference extending between the fixed-side half 20 and the movable-side half 21, and a plurality of rotating rollers 2 </ b> A whose axis is a direction orthogonal to the discharge direction of the roll bale A 2L, a forming belt 2M wound so as to surround the rotating rollers 2A to 2D of the fixed-side half 20, and a forming belt 2N wound so as to surround the rotating rollers 2G to 2I of the movable-side half 21 It is a thing of the form provided with.

  The rotating roller 2A constitutes the lower end portion 20A of the fixed-side half 20, the rotating roller 2B constitutes the lower end portion 23A of the insertion port 23, and both the rotating rollers 2A and 2B both form the forming belt 2M. It constitutes an end portion to be wound. The rotating rollers 2C and 2D are for preventing excessive deformation of the forming belt 2M during the forming of the roll bale A, and are positioned so as to be surrounded by the forming belt 2M between the rotating rollers 2A and 2B. The rotating roller 2E constitutes the upper end portion 23B of the charging port 23 and is for forming the roll bale A. The rotating roller 2F constitutes the upper end portion 20B of the fixed-side half portion 20. And for forming the roll veil A.

  The rotating roller G constitutes the lower end portion 21A of the movable half 21 and constitutes one end portion around which the forming belt 2N is wound, and the rotating roller 2H constitutes the other end portion around which the forming belt 2N is wound. To do. The rotating roller 2I is for preventing excessive deformation of the forming belt 2N during the forming of the roll bail A, and is positioned so as to be surrounded by the forming belt 2M between the rotating rollers 2G and 2H. The rotating rollers 2J to 2L are for forming the roll bale A, and the rotating roller 2L constitutes the upper end 21B of the movable-side half 21.

  The rotating rollers 2A to 2F are pivotally supported by side plates 24 and 24 constituting both side portions of the fixed half portion 20, and the rotating rollers 2G to 2L are supported by side plates 25 and 25 constituting both side portions of the movable side half portion 21. It is pivotally supported.

  When the movable side half 21 is closed, the side edges of the side plates 24, 24 and the side plates 25, 25 are in contact with each other, and the cylindrical roll bale A can be formed by this contact. The forming space 26 is secured (see FIGS. 3A and 3B), and the movable half 21 is opened, whereby the discharge port 27 of the fixed half 20 is opened and the formed roll bale A is discharged. (See FIG. 4).

  The forming belt 2M is also wound around a slide roller 2O that is slidably supported on the side plates 24, 24 over the material-to-be-molded material input side and the roll bail A discharge side. The slide roller 2O is urged toward the material-to-be-molded side by an urging portion 2P made of a tension spring. The urging force of the urging portion 2P keeps the forming belt 2M tensioned. keeping.

  The forming belt 2N is also wound around a side roller 25, a slide roller 2Q that is supported so as to be slidable between the material to be molded input side and the roll bail A discharge side. The slide roller 2Q is urged toward the discharge side of the roll bail A by an urging portion 2R made of a tension spring, and the urging force of the urging portion 2R holds the molded belt 2N so that it is always stretched. doing.

  That is, since the forming belts 2M and 2N are always stretched, the frictional force caused by the rotation of the forming belts 2M and 2N can be applied to the material to be molded in an equilibrium and efficient manner.

  The slide roller 2O is slidably fitted in a long hole 24A that is opened with the longitudinal direction of the side plates 24, 24 as the discharge direction of the roll bale A, and the slide roller 2Q is slid in the longitudinal direction of the side plates 25, 25. The roll bale A is slidably fitted to the long hole 25A opened as the discharge direction of the roll bail A.

  Note that the sliding direction of the slide rollers 2Q and 2O is not limited to the above-described direction as long as the forming belts 2M and 2N can be held in a state of being always stretched.

  In the present embodiment, the angle between the forming belt 2M and the forming belt 2N facing the forming space 26 (forming chamber 2) is 75 ° to 80 ° before the material to be formed is input or at the beginning of the formation of the central core A1.

  The reason why the above-mentioned angle range is 60 ° to 120 ° is that when the angle is less than 60 °, the frictional force due to the rotation of the forming belts 2M and 2N becomes too large as the frictional force that rotates the molding material. This is because the central core A1 being formed may be destroyed by the frictional force. If the angle exceeds 120 °, the frictional force due to the rotation of the forming belts 2M and 2N is insufficient as the frictional force for rotating the molding material, and the formation of the central core A1 may be inefficient. Because there is.

The urging portion 2R is provided on both of the side plates 25 and 25, and one end is hooked on the end portion side of the slide roller 2Q and the other end is hooked on the side plate 25 side.

  Next, the specific configuration of the urging portions 2P and 2R will be described with reference to FIGS. 5A and 5B. The urging portions 2P and 2R are attached so that the urging directions are symmetrical in the drawing. Since it is the thing of the same structure except being described, description of the urging | biasing part 2R is abbreviate | omitted by demonstrating the structure of the urging | biasing part 2P.

  The urging portion 2P hooks two tension springs 200 arranged such that the expansion / contraction direction is the same as the longitudinal direction of the long hole 25A, and one end of the tension spring 200, and the end of the slide roller 2O. It comprises a support plate 201 that pivotally supports the portion, and a fixed plate 202 that holds the other end of the tension spring 200 and is fixed to the side plate 24. The support plate 201 is provided with a latch piece 203 for latching one end of the tension spring 200, and the fixing plate 202 is provided with two latches for latching the other end of the tension spring 200.
