  The volume reduction method in the prior art is a method in which waste is compressed and deformed for each packing unit by a reciprocating compression device, transported to a bagging position, and packed, so that the device becomes complicated and large, and the waste is compressed. It is necessary to configure the part with a robust member, which causes inconvenience that the manufacturing cost increases. On the other hand, the screw press system in which the volume is reduced by compressing and deforming by rotation of the helical body has a simple structure and can be configured compactly. However, since the volume-reduced molding is continuously connected in a rod shape from the volume-reducing device and pushed out, it is necessary to separate the packaging unit for each packaging unit. It was.

  In order to solve the above-mentioned problems, a screw press device that compresses and reduces volume by rotating waste and a spiral body, a packing unit that packs the waste reduced by the screw press device, and a control unit that controls these units The packing means pushes and inserts the reduced volume waste into a long cylindrical thin film material, and inserts the inserted waste into the frame together with the thin film material for a predetermined length. By inserting and inserting and moving the frame body while holding it with the fitting resistance of the waste, the waste connected in a rod shape is separated, and the thin film material of this separation part is cut and joined and packed.

  Further, the frame body for fitting and inserting the reduced volume waste for a predetermined length is provided so as to be able to press-hold and release the fitted waste.

  By adopting the above-described configuration, the inserted waste is securely held in order to insert the extruded waste into the frame, and the waste connected in a rod shape by moving the waste is predetermined. Can be separated and packed into lengths, and packs the volume-reduced waste so that it does not lose its shape during transport or storage, and the waste is not scattered and the storage location and transport device are soiled. Nor. In addition, it also prevents odors from waste and enables long-term storage. Further, the automatic control of the apparatus can minimize the man-made work, and the continuous volume-reducing packaging work can be performed, so that the structure is simple and the apparatus can be configured compactly. In addition, if the frame is configured so that the waste can be pressed and held, the frame side can be reliably held when separating the connected and extruded waste.

Is.

  The machine press 1 is equipped with a screw press device 29 that compresses and deforms waste by rotating the spiral body and reduces the volume, and a packing device 30 that packs the waste that has been reduced in volume by this is installed. The apparatus is configured by providing control means for controlling in the operation panel 10.

  When a waste such as paper or plastic is introduced from the inlet 2a opened at the top of the hopper 2, it is roughly crushed by the crushing rotor 3 and dropped onto the lower screw 7 part. The power of the crushing motor 4 is decelerated by the rotor speed reducer 5 to drive the crushing rotor 3. The crushing rotor 3 is provided with a pair of crushing cutters 3a arranged in the axial direction in a horizontal direction so that the crushing cutter 3a crushes wastes and feeds the wastes downward. It is rotated in the direction.

  The waste material roughly crushed and dropped onto the screw 7 is sent to one end of the screw and pressurized by rotating the screw 7. A pressure molding unit 16 is provided on the conveyance end side of the screw 7 to change the passage cross-sectional area through which the conveyed waste passes, and press-molds the waste passing therethrough. The preload shutter 15 provided is for temporarily compressing the reduced volume waste A at the start of compression to the passage of the casing 6 to provide an initial passage resistance of the waste. When the predetermined pressure is reached, the shutter cylinder 11 The preload shutter 15 is pulled upward, and the waste A is pushed out to the pressure molding unit 16. As for the open / close state of the shutter, a signal is sent to the control unit by the open shutter sensor 30h and the closed shutter sensor 30j.

  The pressure molding unit 16 is provided with a rotation fulcrum on one inlet side of the molding plate divided up and down, and the outlet side is rotated up and down by the press cylinder 12 to change the cross-sectional area through which the compressed waste passes. And adjust the pressure forming pressure of the waste. The shape of the cross section is formed in a cylindrical shape or a polygonal shape.

  Waste material that has been pressurized through the pressure molding unit 16 is sent to the guide tube 18. A long cylindrical thin film material 17 whose one end is closed is inserted into the outer periphery of the guide tube 18 while being compressed in the axial direction of the guide tube 18. As a result, the waste is pushed out from the guide tube 18 while pushing the closed end of the thin film material 17, so that the waste is contained in the thin film material 17 and pushed out.

  The waste pushed out from the guide tube 18 is fitted into the frame 30a and further pushed forward through the frame. The waste to be pushed out is controlled by a count wheel 30c provided in the pressure molding unit 16 rotating along with the movement of the waste, which is detected by the length sensor 30b and sending a signal to the control unit. Extruded. When the predetermined length is pushed out, the screw 7 is stopped and the pressure pushing is stopped once.

  The frame 30a is provided on the conveyor 20, and is configured to be movable back and forth on the conveyor by the expansion and contraction of the frame moving cylinder 14, and the waste fitted and inserted into the frame 30a is compressed. Since the inner wall of the frame body 30a is pressed and integrated by its own restoring force, when the frame body is moved forward, it works to tear the waste that is connected and pushed out, and the frame body 30a and the guide tube 18 In between, the waste is separated in the thin film material.

  The portion of only the thin film material that has been moved and separated is held from above and below by the seal portion 19 at the middle portion of the package, and is welded and joined by electric heat. Moreover, it cuts with a cutter simultaneously with joining, and packing of a waste is completed.

  3, 4, 5, and 6, the process of separating and packing waste by moving the frame will be described. FIG. 3 shows a state in which the frame body 30a approaches the guide tube 18 and the waste material pushed out from the guide tube is fitted and inserted into the frame body 30a together with the thin film material 17. The provided length sensor 30b provides a plurality of acute teeth on the circumference, and detects the rotation of the count wheel 30c that rotates with the pushing out of the waste by causing one end of the teeth to bite into the waste. When a predetermined length is reached, the screw 7 is stopped, the pressure extrusion is temporarily stopped, and the fitting insertion length is determined.

FIG. 4 shows a state when the thin film material is welded. After the pressure extrusion is stopped, the frame 30a is moved forward on the conveyor 20 by the frame moving cylinder 14 and separated from the guide tube 18. It is. At this time, the waste in the frame 30a is moved integrally with the frame by pressing the wall of the frame by the compressed restoring force, and the waste is removed from the thin film material 17 between the guide tube 18 and the frame 30a. Separated inside. The separation may be performed by moving in the vertical direction before moving the frame 30a forward.

  The gap of only the thin film material that has been moved and separated serves as a space for welding the thin film material of the seal portion 19. 17 is held and welded and joined by electric heat. At the same time as joining, the film is cut back and forth with a cutter, the thin film material is cut off, and packing of one waste is completed.

  This clamping joint position is located at the upper and lower intermediate portions of the volume-reduced waste, and the lower sealer head 26 is lifted by the lower sealer head 26 from below, so that the lower sealer head 26 is bordered on the inner surface of the thin film material 17. In this way, inclined surfaces are formed on the left and right sides, so that the internal residue in the intermediate portion is distributed and welding joining is performed reliably.

  As shown in FIG. 5, the waste whose packaging has been completed is moved again to the guide tube 18 by the frame moving cylinder 14 while being stored in the frame 30a. When the approach is completed, the screw 7 on the screw press device 29 side rotates, and the extrusion of waste is resumed. When the extrusion is resumed, the packaged waste in the frame 30a is pushed out of the frame 30a by the unpacked waste pushed out as shown in FIG. 6, and the packing operation is continuously performed.

  The operation of the seal portion 19 will be described with reference to FIGS. FIG. 7 shows a state in which the joint cutting portion of the thin film material 17 is opened. The upper sealer head 25 that holds the thin film material 17 from above and is welded by electric heating cuts the thin film material 17 to the upper head support material 27. Attached to both front and rear sides of the cutter 24. The upper head support member 27 is slidably attached to the guide member 21 at both sides, and is connected to the cutter support member 23 supporting the cutter 24 by springs 28 on both sides.

  The cutter support member 23 is connected to the support frame member 22 by the seal cylinder 13, and the lower sealer head 26 is attached to the support frame member 22 so as to face the upper sealer head 25. When the support cylinder member 22 is attached to the guide member 21 so as to be slidable in the vertical direction and the seal cylinder 13 is extended, the upper sealer head portion and the lower sealer head are brought close to each other to guide the thin film material 17. The shrinkage sensing switch 30f and the elongation sensing switch 30g sense the sealer head position and transmit it to the control unit.

  FIG. 8 shows a state in which the seal cylinder 13 is extended and the joint cutting portion is closed. The thin film material 17 is held between the upper sealer head 25 and the lower sealer head 26 by the elastic pressure of the spring 28 and is welded by electric heat. Join.

  When the seal cylinder 2 is further extended after the thin film material 17 is held by the upper sealer head 25 and the lower sealer head 26, the cutter 24 cuts the thin film material 17 through the holding surface from the top to the bottom. At this time, the upper sealer head 25 and the lower sealer head 26 are not directly affected by the pressure applied by the seal cylinder 13 due to the action of the spring 28 connecting the cutter support member 23 and the upper head support member 27. The sealer head is protected and pressurized by the spring pressure of the spring 28.

  9 and 10 are cross-sectional views in a state where the upper sealer head 25 and the lower sealer head 26 are in contact with each other. FIG. 9 is a state before the cutter 24 passes through the holding surface, and FIG. It shows the state of passing through. A pair of the upper sealer head and the lower sealer head are provided on the front and rear sides of the cutter, respectively, and the packing side and the unpacking side of the thin film material 17 are welded and joined at the same time.

  FIG. 11 is a front view of an example in which a frame for fitting and inserting extruded waste is divided into upper and lower parts, and the upper and lower parts are connected by a cylinder so that the inserted waste can be pressed and held or released. It is sectional drawing. The frame body is divided into an upper frame body 30k and a lower frame body 30l, and both sides are held by holding cylinders 30m and 30m, and the holding cylinder 30m is expanded and contracted to remove inserted waste. It is possible to add resistance at the time of separating the pressed and connected waste, or to push the waste away from the top and bottom. The frame is moved back and forth on the conveyor 20 by the frame moving cylinder 14 provided below the lower frame 30l.
