Description

  The present invention relates to a volume-reducing bagging machine that compresses soft waste disposal products such as paper scraps and vinyl and packs them into a storage bag.

  When transporting or storing waste, if the same, the smaller volume is naturally advantageous during transport and storage, and a method for reducing the volume by compressing and deforming waste is shown in Japanese Utility Model Laid-Open No. 5-13696. There are known methods for compressing waste by pushing it into the compression chamber with a press plate using a cylinder or the like, and methods for compressing waste by pushing the screw by rotating the screw as shown in registered utility model No. 3022441. It has been.

In addition, the reduced volume of waste can be packaged to prevent the molding from collapsing during transportation or spillage of parts that could not be integrated, and also to prevent bad odors from the waste. It is valid.
Japanese Utility Model Publication No. 5-13696 Registered Utility Model No. 3022241

  The volume reduction device of the vertical press type as shown in Patent Document 1 in the prior art has a small installation area, but a vertical cylinder that moves up and down as in the press cylinder and this example publication has a compression chamber. These spaces are required to protrude upwards with a length equal to or greater than the compression stroke. As the area of the compression chamber press plate in plan view increases, even if it is compressed with the same force, Therefore, the cross section of the storage bag and the size of the press plate need to have substantially the same shape, and the size of the storage bag is also limited. For this reason, in order to raise a pressure, it is necessary to comprise the whole apparatus with a robust member, and there exists a problem which enlarges or a manufacturing cost increases. Furthermore, there is a problem that waste cannot be continuously fed because the press plate reciprocates.

  In addition, the screw volume reduction device disclosed in Patent Document 2 is configured to push paper waste into a storage bag provided below by a screw conveyor provided with a rotation shaft in the vertical direction, and can be configured compactly. However, the upper and lower positions of the screw and the storage bag are fixed, so if the paper waste does not store until it reaches the screw outlet of the storage bag, the paper waste will not start to be compressed, and the volume will not be reduced if it is collected halfway. This will cause inconvenience of being collected.

  In this example, since it is a relatively small volume reduction device that assumes waste bins, it can be imagined that the storage bag can be replaced by removing the upper part, which is the screw part, but a certain amount of processing When processing an object, the efficiency is poor, and when trying to improve the capacity, there is a problem that the size of the screw portion becomes large and the handleability deteriorates.

  For this reason, an object of the present invention is a volume-reducing bagging machine that can efficiently process soft waste such as paper waste and vinyl, which is small in size and has a small installation space, and the bag holding portion is a storage bag. Easy to install and remove, waste treatment can be uniformly pressurized and reduced, and stored in a storage bag, reducing the volume of soft waste that is easy to post-process without spilling from the bag after storage It is to provide a bagging machine.

  In order to solve the above-mentioned problems, there is an inlet for throwing in the waste material, a screw body having a rotation shaft in the vertical direction for conveying and compressing the waste treatment material, and a screw body outlet for storing the waste treatment material. In a soft waste volume reduction bagging machine configured with a bag holding section for holding a storage bag and a control device for controlling these, the bag holding section is a bag holding bracket provided on the volume reduction apparatus main body side. The present invention provides a soft waste volume reduction bagging machine characterized by comprising a storage bag attached and a detachable metal fitting that is detachable from a bag holding metal fitting.

  Further, in the volume reduction bagging machine, the detachable metal fitting has a hole having a diameter substantially the same as the inner diameter of the screw body outlet part, and the lower part of the hole has a conical bag guide part that widens toward the bottom, Provided is a soft waste volume reduction bagging machine characterized in that an inlet portion of a storage bag is inserted into an inner surface of a hole, and a peripheral end portion of the storage bag inlet is sandwiched and held between a bag holding metal fitting and a detachable metal fitting.

  The volume reduction of the soft waste is characterized in that the screw tip portion on the screw body outlet side is located on the storage bag side below the storage bag holding surface of the bag holding fitting and the detachable fitting of the bag holding portion. A bagging machine is provided.

  By providing a screw body with a rotating shaft in the vertical direction and providing a storage bag at the outlet, it is possible to provide a small volume reduction device with less installation space. In addition to being able to be charged, a large deformation and compression force can be obtained with a relatively simple member, so that the manufacturing cost does not increase.

  The waste treatment product introduced from the introduction port is deformed and compressed in the screw body by the screw body having a rotation shaft in the vertical direction, and is finally pressurized and reduced in the storage bag by the extrusion pressure. Since the detachable brackets that can be set in the storage bag are detachable, they can be set independently without being affected by the state of the main body, and by preparing multiple detachable brackets, the bag can be set even when the device is in operation. It is also possible to keep work efficiently.

  Further, the detachable fitting has a hole having substantially the same diameter as the inner diameter of the screw body outlet portion, and the lower portion is provided with a conical bag guide portion that spreads downward toward the bottom, so that the compressed waste disposal product is Dispersed downward and stored in a storage bag, can be stored in a storage bag with a diameter larger than the outer diameter of the screw body, and it is difficult to apply local pressing force or biased back pressure to the shoulder of the bag entrance. The input part is uniformly pressurized and stored in the bag without damage.

  Also, because the screw tip is located below the storage bag clamping surface of the bag holding bracket and the detachable bracket, when the storage bag is full and the storage bag is removed, the waste material is packed to the screw tip position. The part where the storage bag is sandwiched from the tip of the screw can be closed to close the bag, preventing spillage of stored waste and preventing bad odors from the waste, and handling the bag after storage. It becomes good.

  Reference numeral 1 denotes a frame for mounting a volume reduction device, which can be moved by a caster 1a. The upper part of the frame 1 is a compressing / conveying part for the waste-treated product, and the lower part is a storage chamber for storing the waste-treated product in a bag. In the screw housing 2b of the compression / conveyance unit, a screw body 2 having a rotating shaft in the vertical direction and compressing and conveying the waste treatment product is provided, and is driven by a motor 10 provided at the rear of the screw body 2. A sprocket 10 a is fixed to the output shaft of the motor 10, and a roller chain 10 b is wound around the sprocket 2 a fixed to the upper end portion of the screw body 2 to drive the screw body 2.

  The waste processed material introduced from the inlet 3 opened obliquely above the screw body 2 is conveyed downward by the spiral blades of the screw body 2 and is deformed and compressed. At the lower outlet portion of the screw body 2, there is provided a bag holding portion 4 for a storage bag for storing a waste treatment product, and a storage bag 40 is attached thereto. The mounting portion of the storage bag 40 has a hole that is substantially the same diameter as the inner diameter of the outlet portion of the screw body 2, and the lower portion of the hole is a conical bag guide portion that spreads downward toward the bottom. The waste disposal product pushed out is dispersed by the bag guide portion so as to spread toward the end in the direction of arrow F, and can be stored in the storage bag 40 having a diameter larger than the inner diameter of the screw body outlet. The lower surface of the storage bag 40 is supported by a table 43 provided so as to be movable in the vertical direction, and the table 43 moves up and down by rotating the motor 42 provided behind the screw housing 2b in the normal direction.

  The roller chain 42b is stretched up and down on a sprocket 42a fixed to the motor 42 and a guide roller 42c rotatably provided on the lower frame, and both ends of the roller chain 42b are fixed to one end of the table 43, respectively. When the normal rotation is reversed, the table 43 moves up and down. A rail 1b having a U-shaped cross section provided in the vertical direction on the frame 1 is arranged on the left and right and the rear of the table 43, and a guide roller 43b provided rotatably on the table 43 is moved with the inside of the U-shaped rail 1b as a guide. By doing so, the table 43 moves in parallel up and down and the storage bag holding surface is held horizontally.

  5, 6 and 7, the process from when the storage bag 40 is set to the bag holding part 4 until the waste product is stored will be described. When the door 5 is opened and the handle 41b of the attachment / detachment fitting 41a is pulled out to the front, the attachment / detachment attachment 41a is detached from the bag holding attachment 41. The inlet portion of the storage bag 40 is inserted into a hole provided approximately the same diameter as the screw body outlet portion inner diameter of the detachable fitting 41a, the bag inlet portion is folded back to the outside of the hole, and is inserted into the bag holding fitting 41 again. When the storage bag 40 is set by holding the part between the attachment / detachment fitting 41a and the bag holding fitting 41 and the door 5 is closed, preparation for the operation of the volume reduction device is completed.

  61a is a door sensor for detecting the open / closed state of the door 5, and is controlled so that the volume reduction device does not operate when the door 5 is open. 61c is a bag sensor for detecting whether or not the detachable fitting 41a is correctly set on the bag holding fixture 41, and is controlled so that the volume reducing device cannot be operated unless it is set correctly.

  The storage bag 40 mounting surface of the table 43 is configured so that it can be pulled out to the near side when the door 5 is opened, and is placed on the table 43 when the heavy storage bag 40 is stored after the waste material is stored. Can be pulled out. Reference numeral 43a denotes a table lock fitting for fixing the drawer portion of the table 43, and the table lock fitting 43a is engaged with and fixed to the lock pin 43c on the table main body side.

  When the operation switch of the control panel 6 is pushed and the device is operated, as shown in FIG. 6, the motor 41c of the bag holding portion 4 is operated to raise the bag holding fitting 41 and attach the detachable fitting 41a to the screw housing 2b mounting portion of the frame 1. And the storage bag 40 attached thereto. When the entrance portion of the storage bag 40 is brought into close contact, the table 43 on which the bottom surface of the storage bag is placed rises, and the storage bag bottom surface is brought close to the outlet portion of the screw body 2 in the state shown in FIG. When the ascent of the table 43 is finished, the screw body 2 is operated, and the waste processed material introduced from the insertion port 3 is conveyed and compressed and pushed out from the outlet portion of the screw body 2 to the storage bag 40.

  The waste processed product pushed out is blocked by the table 43 on which the bottom surface of the storage bag 40 is placed, and is pressed in the storage bag 40. A load acts on the screw body 2 by the reaction force that is pressed, and the current value of the driving motor 10 changes. By controlling the table 43 to be lowered so that the current value becomes constant, the pressing force becomes constant, and the waste processed material that has been reduced in volume by being uniformly pressed into the storage bag 40 can be stored.

  The vertical position of the table 43 is detected by each sensor arranged in the vertical direction on the rear side of the table, and the vertical position is controlled by the control unit. 61d is a bag table upper limit sensor for sensing the upper limit position of the table 43, and the raised table stops rising at this position. Reference numeral 61g denotes a full position sensor, which senses when the waste bag 40 is filled with the waste processing product and the table 43 is gradually lowered and becomes full, and stops the screw body 2 to stop the filling. When the holding metal fitting 41 is lowered and the table 43 is further lowered to detect the take-out position sensor 61h, the descent stops and the storage bag 40 can be taken out.

  Since the distal end portion on the outlet side of the screw body 2 is positioned on the side of the storage bag below the storage bag sandwiching surface of the bag holding metal fitting 41 and the detachable metal fitting 41a, the front end of the screw body 2 is removed when the storage bag 40 is full. The portion of the bag sandwiched from the portion becomes the bag closing allowance, and the bag can be closed.

  8 and 9, the bag holding part 4 will be described. The bag holding metal fitting 41 has a horizontal surface on which the detachable metal fitting 41a is placed, and a plurality of round bar-shaped guide bars 41h projecting in a direction perpendicular to the horizontal surface are inserted into the guide boss 1c provided on the frame 1 side to be guided, thereby causing the vertical direction. It is comprised so that it can go up and down in parallel.

  The raising and lowering of the holding metal fitting 41 is activated by driving a motor 41c provided on the front side of the screw body 2 below the insertion port 3, and a boss portion provided at an intermediate portion of the swing arm 41d is fixed to the output shaft of the motor 41c. One end of the swing arm 41d extends to the outer periphery of the motor output shaft provided with the bag holding lock sensor 61e and the bag holding release sensor 61f for sensing the rotational position. Activate each sensor.

  Further, the other end of the swing arm 41d is fixed to an arm extending horizontally in the horizontal direction, and one end of the link arm 41e is rotatably connected to the left and right ends of the arm. The other end is connected to a vertical movement arm 41f that raises and lowers the bag holding metal fitting 41. The vertical movement arm 41f is attached with an arm shaft 41g fixed on the frame 1 side as a rotation fulcrum, one end connected to the link arm 41e, and the other end in the horizontal direction of the bag holding bracket 41. When the motor 41c is engaged with the extended vertical movement pin 41j through a long hole and the motor 41c rotates, the arm that extends horizontally in the horizontal direction moves the link arm 41e back and forth, and the vertical movement arm 41f moves up and down. The bag holding metal fitting 41 is moved up and down by rotating in the direction.

  The vertical position of the bag holding metal fitting 41 is controlled by signals from the bag holding lock sensor 61e and the bag holding release sensor 61f provided in the motor 41c, and the motor 41c moves the bag holding metal fitting 41 when the bag holding lock sensor 61e operates. It stops at the raised position, and stops at the lowered position when the bag holding release sensor 61f is activated.

  The detachable metal fitting 41a is for setting the storage bag 40, and is detachable from the bag holding metal fitting 41. In the cylindrical part having a hole provided with substantially the same diameter as the inner diameter of the outlet of the screw body 2, a screw is attached. The body 2 outlet side is provided with a ring-shaped collar in the horizontal direction, and the lower part has a conical bag guide part that expands downward, and the inlet part of the storage bag 40 is inserted into the cylinder from below. Then, the bag entrance portion is folded back to the ring-shaped collar, wound as shown in FIG. 9, and inserted into the U-shaped holding surface of the bag holding metal fitting 41 so as to be held and held by the flange portion. At this time, the closing allowance when closing the bag can be adjusted by adjusting the winding amount of the storage bag.

  Further, when the bag holding metal fitting 41 rises and comes into close contact with the screw housing 2b mounting plate of the frame 1, the storage bag 40 is securely held by being held between the bag holding metal fitting 41 and the frame 1 side. Reference numeral 41b denotes a handle for attaching / detaching the attaching / detaching bracket 41a. The control unit is configured so that the bag set sensor 61c senses whether the detachable fitting 41a is securely inserted into the bag holding fitting 41, sends a signal to the control unit, and the apparatus does not operate unless it is set correctly.

  The control operation by the control circuit will be described with reference to the flowchart of FIG. When the power switch is turned on (S1), the power lamp is turned on to check whether the operating conditions are adjusted. In the case of the operating condition shown in S2, the operation of the apparatus cannot be started, and all the apparatuses are stopped even during the operation.

  The operating condition (S2) is that when the emergency stop switch is pressed and turned on, an overload is applied to each motor in the device and the overload protection device is activated. In the case of OFF, when the table 43 on which the storage bag 40 is placed is pulled out and the bag set sensor 61c is OFF, the lamps of the control panel 6 provided on the side of the waste processing material inlet 3 are lit and the operating status Is displayed.

  The selector switch can be switched between automatic operation and manual operation. When the operation switch is switched to automatic operation (S3) and the operation switch is turned ON (S4), the device starts operation and holds the bag in which the storage bag 40 is set. When the holding portion is raised (S5) and the bag holding lock sensor provided in the motor 41c senses, the raising stops and the storage bag inlet portion is brought into close contact with the outlet portion of the screw body 2 (S6). Next, the table 43 on which the bottom surface of the storage bag 40 is placed is raised (S7), and stopped when the bag table upper limit sensor 61d is turned on (S8).

  When the table 43 is stopped, the screw body 2 is rotated (S9), and the waste processed material introduced from the insertion port 3 is deformed and compressed by the screw and is conveyed to the lower storage chamber side and pushed out. The extruded waste product is blocked by the table on the bottom surface of the storage bag 40 and pressed and compressed. If the pressing continues further, the pressing force increases, and the reaction force also increases the load of the motor 10 that drives the screw body 2 proportionally, and the table 43 is lowered so as to keep this load current constant. The storage pressure in the storage bag 40 is kept constant.

  The screw body 2 rotates and the load current of the motor 10 is detected (S10). When the set load current value is reached, the table 43 descends for a predetermined time and stops. This is repeated, and when the table 43 reaches the full position sensor 61g position (S11) and the load current value reaches the set value, the rotation of the screw body 2 is stopped and the pushing out of the waste processed material is stopped (S12).

  Next, the bag holding fitting 41 of the bag holding part 4 is lowered by driving the motor 41c, and when the bag holding release sensor 61f provided in the motor 41c part senses, the motor 41c is stopped and the lowering is finished (S13). Subsequently, the table 43 on which the storage bag 40 is placed is lowered and stopped when the take-out position sensor 61h senses (S14), the operation lamp is turned off, the completion lamp is turned on, and the storage bag 40 in which the waste disposal product is stored is removed. It can be taken out.
