Description

  The present invention relates to a waste material input device in a compression molding machine that forms waste materials such as corrugated cardboard, vinyl, plastic bottles, paper scraps, and fabrics into blocks that are easy to transport for recycling.

As the above-described compression molding machine for waste material for recycling, a horizontal molding chamber provided with a discharge port at the front end and a supply opening in the middle, and a compression device that reciprocates in one of the molding chambers are provided, Also known is a waste material supply cylinder disposed above the supply opening. For example, Japanese Patent Publication No. 51-10429 (Patent Document 1) states that “a longitudinally extending compression chamber having a discharge opening at the front end and a supply opening at the rear end, a position for closing the discharge opening, and a position of the chamber A first gate supported for movement in an open position allowing application of the container around the front, a chute in communication with the supply opening, an advanced position close to the discharge opening and a leading edge of the supply opening; A ram movable longitudinally between subsequent retracted positions, a second gate means for opening and closing the supply opening by retreating and advancing the ram, means for sensing the substance in the chute, and advancing the ram Drive means for retracting, automatically actuating the drive means in response to the position of the sensing means and the first gate, thereby retracting the ram to open the supply opening gate means, Lamb It discloses a compaction apparatus "and a control means for closing the supply opening gate means is advanced to the scheduled intermediate position between said forward and retracted positions.
Japanese Patent Publication No.51-10429

  According to the technique disclosed in the above-mentioned publicly known document, a rectangular plate for gate formation is fixed to the upper edge of the ram toward the rear, and the waste material from the chute (waste material supply cylinder) is received to compress and compress the ram. A shearing blade is installed along the front top edge of the ram plate to enable the action. As shown in FIG. 1, when the forming chamber of the supply opening is filled, the shear blade is stored on the supply side and the protruding waste is placed on the top edge of the front surface of the ram plate 10 and the upper portion of the forming blade. The edge is cut as the receiving blade 25 ′. However, there is a problem that an impact force is generated as a reaction force at the time of cutting and a large vibration is generated in the airframe with energy consumption.

  In order to solve the above problems, a horizontal molding chamber having a discharge port at the front end and a supply chamber in the middle, and a compression device having a reciprocating ram plate are provided on the other side of the molding chamber, A supply opening is provided in the upper wall of the supply chamber, and in the compression molding machine in which a waste material supply cylinder is erected in this supply opening, a pressing plate that traverses the entire surface of the supply opening in the waste material supply cylinder can be freely rotated. And a waste material charging device in a compression molding machine provided with a guide plate for shielding waste material on the upper surface of the pressing plate.

  In addition, a configuration is provided in which a locking device is provided on the side of the molding chamber at the tip of the pressing plate provided in the waste material input device of the compression molding machine.

  A pressure plate that crosses the entire surface of the molding chamber supply opening is rotatably installed inside the waste material supply cylinder of the compression molding machine, and a guide plate for waste material shielding is provided on the upper surface of the pressure plate. Even if the upper edge of the moving ram plate is not provided with a shearing blade, the upper surface of the waste material stored in the supply opening of the waste material supply chamber is pressed by the pressing plate and substantially coincides with the upper wall of the molding chamber. To slide. In addition, a substantially arc-shaped guide plate is projected on the upper surface of the pressing plate, so that the waste materials that are sequentially sent are received and separated, and the stored waste materials are smoothly slid and returned during the return operation. The operation of separating and compressing the waste material in the forming chamber supply section while temporarily storing the waste material sent to the cylinder on the upper surface of the guide plate has become possible.

  In addition, since the lock mechanism is provided at the tip of the pressing plate, the locking device receives and disperses the back pressure to be pushed back to the pressing plate when the ram plate is compressed, so that the pressing plate does not bend. Therefore, the hydraulic cylinder used for rotating the pressing plate is minimal and economical.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram according to the prior art, FIG. 2 is a side view of a part of the embodiment of the present invention, FIG. 3 is an external perspective view, and FIG.

  This will be described with reference to FIGS. Reference numeral 1 denotes a molding chamber which is a horizontally long cylinder having a quadrangular cross section and is formed of an upper wall 24 and left and right side walls 22. A compression device 2 having a discharge port 16 at the front end, a supply chamber 3 in the middle, and a ram plate 10 reciprocating on the other is provided.

  The ram plate 10 moves horizontally within the molding chamber 1 and is driven by a piston rod 12 of a reciprocating cylinder 11. Reference numeral 17 denotes a gate plate, which blocks the waste compression material introduced by partitioning the end of the discharge port 16 and is driven up and down by a lifting cylinder 23. Reference numeral 20 denotes a binding string groove provided in parallel on the left and right side walls 22, which is a gap for manually passing waste string compressed to a predetermined hardness.

  Reference numeral 13 denotes a supply opening, which is formed by notching the upper part of the supply chamber 3 on the upper wall forming the molding chamber 1. A waste material supply cylinder 4 is erected above the supply opening 13. Reference numeral 5 denotes a pressing device, which is provided inside the waste material supply cylinder 4, and rotates the pressing plate 6 and the guide plate 7 around the hinge 8 as a fulcrum. A rotating cylinder 9 rotates the pressing plate 6 and the guide plate 7.

  The pressing plate 6 is formed so as to substantially match the opening shape of the supply opening 13. The guide plate 7 is formed so as to protrude in an arc shape (one quarter of a circle) around a hinge 8 provided on the base side of the supply chamber 3 when the pressing plate 6 reaches the pressing position. Therefore, while the pressing plate 6 of the pressing device 5 is set from the supply opening 13 of the supply chamber 3 and the compression device 2 is driven, the next waste material falls and accumulates on the upper surface of the guide plate 7. When 6 returns, the upper surface of the guide plate 7 is set to the initial position by smoothly sliding the arc-shaped guide plate 7 protruding from the lower surface of the accumulated waste material.

  Reference numeral 14 denotes a locking device, which fixes the tip of the pressing plate 13 to the upper wall 24 side of the molding chamber 1 when the pressing plate 6 is set at a pressing position with respect to the supply opening 13 of the supply chamber 3. Reference numeral 15 denotes an electric cylinder, and 18 hooks are engaged and fixed to a notch engaging portion 19 provided at the tip of the pressing plate 6 via a link.

  When the tip of the pressing plate 6 is locked, the back pressure generated when the ram plate 10 moves through the supply chamber 3 and compresses the waste material is distributed to the locking device 14 at the tip of the pressing plate 6. The back pressure 6 receives on the hinge 8 as a fulcrum is eliminated. Therefore, since the capability of the rotation cylinder 9 is sufficient only for the rotation load of the pressing device 5 itself, the minimum size is sufficient.

  The operation of the locking device 14 is automatically locked and released when interlocked with the operation control of the rotating cylinder 9 that operates the pressing plate on the pressing device 5 side.

  The operation of the waste material input and the pressing device will be described with reference to FIG. At the beginning of the operation of the compression molding machine of the present invention, the gate plate 17 of the discharge port 16 is lowered and closed. The pressing plate 6 of the pressing device 5 shortens the rotating cylinder 9 and stands upright so as to be along one side surface of the waste material supply cylinder 4. In this state, when the waste material is introduced into the waste material supply cylinder 4, the waste material passes through the supply opening 13 and stays in the supply chamber 3. When the pressing plate 6 is rotated by an appropriate amount and the supply opening 13 is securely closed and locked, the ram plate 10 is reciprocated to compress the waste material into the molding chamber 1. The waste material supplied into the waste material supply cylinder 4 during the compression molding operation is stagnant in the upper part of the guide plate 7. However, when the pressing plate 6 returns to the initial stage and rotates around the hinge 8 as a fulcrum, it has an arc shape. The surface slides smoothly on the lower surface of the waste material.

  In particular, bulky waste materials such as cardboard are stacked on the supply opening 13 at the time of charging. Therefore, it is efficient to divide the pressing plate 6 into the supply chamber 3 several times and lock it when a predetermined amount is reached, and compression molding. When the predetermined amount is reached in the molding chamber 1, the string is transferred from the binding string groove 20 in the horizontal direction and is bound by a known operation. When the gate plate 17 is raised and discharged by the ram plate 10, the package 21 is completed.
