Description

  The present invention relates to an apparatus for compressing and solidifying fiber strips.

  2. Description of the Related Art Conventionally, from the viewpoint of personal information protection and the like, document shredder apparatuses for cutting a confidential document that is no longer necessary, releasing the confidentiality, and discarding the document are widely known.

  A conventional document shredder apparatus mainly uses a method of cutting waste paper with a cutting blade. However, waste paper that has been finely cut by such a method, that is, fiber strips, has a short fiber length, making it unsuitable for repeated recycling and can be used as incinerated fuel or only recycled to toilet paper. It was. Therefore, in recent years, a shredder shredding device has been proposed that can hold the fibers of the waste paper after treatment for a long time by tearing the waste paper instead of cutting it, and can provide shredded paper suitable for recycling. (For example, patent document 1).

Such shredded shredder apparatus is provided with a compression-solidifying device that compresses the crushed paper having an increased capacity after the crushing process is performed on the waste paper as fiber strips. The compression-solidifying device has a compression case disposed in the vertical direction, and includes a conveying screw for conveying the crushed paper accumulated in the compression case and a compression roller for compressing the crushed paper. In the case, the crushed paper is operated to be compressed by the compression roller while being conveyed by the conveying screw in the gravity direction from the upper side to the lower side.

  However, in the conventional compression-solidifying device, the shredded shredded paper is compressed in the vertical direction while transporting shredded paper in the vertical direction. In the compressed state, it is difficult to proceed downward, and gradually stays in the conveying screw part. Finally, it remains as a compressed lump, and the conveying screw itself stops operating. There was a possibility that it could not be transported. In order to avoid such a state, it is necessary to enlarge the compression conveyance path so as not to stagnate the compressed mass on the way, but there is a possibility that the apparatus itself becomes larger by that amount.

  The present invention is a compression that can be sufficiently transported without increasing the size of the compression and solidification device for the crushed paper such as fiber strips, and does not re-expand the crushed paper after compression. The object is to provide a solidification apparatus.

  The invention according to claim 1 is a rectangular transport case for storing fiber strips, a linear spiral screw mounted with a fixed space formed on the outer periphery of a rotating shaft pivoted in the transport case, And a compression blade provided in front of the spiral blade body, wherein the compression device transfers the fiber strips fed by the spiral blade body into a compression case. A contact plate received by the contact plate, a contact plate operating mechanism that moves the contact plate back and forth in and out of the compression case, and a biasing mechanism that is attached to the contact plate operating mechanism and biases the contact plate into and into the compression case. It is characterized by comprising.

  The invention according to claim 2 is characterized in that the abutment plate operating mechanism is configured such that the abutment plate is pivotally supported on an abutment plate shaft disposed outside the compression case, and the abutment plate is centered on the abutment plate axis. The present invention is characterized in that the abutting plate is configured to advance and retract from the slit formed in the compression case by the rotation of the plate.

  According to a third aspect of the present invention, the urging mechanism includes a spring interposed between the working base of the plate and a urging frame, and gradually energizing force as the fiber strip is pumped against the plate. It is characterized by having comprised so that may decrease.

  According to a fourth aspect of the present invention, the spiral screw mounted in the transport case is divided into a front-stage screw and a rear-stage screw, and a holding plate for pivoting the rotation shaft of each screw is disposed in the divided portion. In addition, a scraping roller that rotates upward is disposed above the holding plate.

  The invention according to claim 5 is characterized in that a paper dust discharge window is formed on the inner bottom surface of the transfer case and a discharge fan is provided.

  According to a sixth aspect of the present invention, at the end of the compression case, a pressed drop for pressing down and dropping the fiber fragment solidified product compressed and solidified in the compression case downward from the compression case. A device is provided.

  According to invention of Claim 1, the rectangular conveyance case which accommodates a fiber strip, the linear spiral screw with which the fixed space was formed in the outer periphery of the rotating shaft pivoted in the conveyance case, and was mounted | worn A helical blade body continuously provided at the tip of the rotating shaft, and a compression device provided in front of the helical blade body. The compression device receives the fiber fragments pumped by the helical blade body in the compression case. A rectangular transport case by a plate, a contact plate operating mechanism that moves the plate back and forth in and out of the compression case, and a biasing mechanism that is attached to the contact plate operating mechanism and biases the contact plate into and into the compression case. The stored fiber strips are conveyed by a linear spiral screw, and the fiber strips fed by the spiral blades are received by the contact plate in the compression case, and a certain volume is formed into a lump of fiber strips of a certain hardness. Can be compressed. As described above, the abutment plate is moved forward and backward by the abutment plate operating mechanism and moved forward and backward, and the urging mechanism is configured to enter and urge the abutment plate into the compression case. The hardness of the lump can be compressed above a certain level, and at the same time, the pressure release force of the lump of the fine fiber fragments gradually releases the plate against the urging force of the urging mechanism and moves out of the compression case. Can be operated. Therefore, without increasing the size of the compression-solidifying device, a large amount of fiber strips can be conveyed by a helical screw, and the fiber strips can be automatically made into a lump of fiber strips compressed to a certain hardness. it can. Further, the compression-solidifying device can be miniaturized while maintaining the conveying force for conveying the fiber strip and the compressing force for compressing the fiber strip.

  According to a second aspect of the present invention, the abutment plate operating mechanism pivotally supports the abutment plate on an abutment plate shaft disposed outside the compression case, and is centered on the abutment plate shaft. The contact plate is always housed in the compression case so that the inside of the box can be moved in and out of the compression case by moving the contact plate into and out of the compression case from the slit formed in the compression case by the rotation of the contact plate. Although it is in a closed state, when a lump of fiber strip is applied to the plate as a constant compression load, it is compressed to become a lump of fiber strip of a certain capacity, and finally the plate is urged from the slit Therefore, it is possible to push the outside of the compression case against the outside of the compression case to open the inside of the compression case, and to extrude and discharge a lump of a certain amount of fiber fine pieces as they are to the outside of the compression case. Since the contact plate can be smoothly withdrawn from the slit, the inside of the compression case can be easily opened, and the fiber fragments can be easily released from the compression case.

  According to a third aspect of the present invention, the biasing mechanism is gradually moved by a spring interposed between the working base of the plate and a biasing frame as the fiber strips are pressed against the plate. By configuring so that the urging force is reduced, the fiber strips of the pressing plate in the compression case have a certain capacity due to the urging force of the spring interposed between the operating base of the pressing plate of the urging mechanism and the machine frame. It can be compressed into a mass of fiber strips. Further, as the fiber strips are pressed against the abutment plate, the urging force of the urging mechanism gradually decreases, so that the urging force of the energizing mechanism spring decreases as the abutment plate approaches the compression case. Since the abutting plate is rotated about the working base, the abutting plate can be smoothly withdrawn, and the inside of the compression case can be easily opened so that the fiber fragments can be easily released from the compression case.

  According to a fourth aspect of the present invention, the helical screw mounted in the transport case is divided into a front stage screw and a rear stage screw, and a holding plate for pivoting the rotation shaft of each screw is provided at the divided portion. Since the spiral screw has a two-stage configuration of a front-stage screw and a rear-stage screw by arranging a scraping roller that rotates upward at a position above the holding plate, The fiber strips can be conveyed to the compression device while being held in a cantilevered manner. In addition, by disposing and rotating the scraping roller, the fiber strips accumulated above the compression case are scraped off, so that the fiber strips are prevented from being compressed and solidified, and the same apparatus can be obtained without any failure over a long period of time. .

  According to the invention of claim 5, by forming a paper dust discharge window on the inner bottom surface of the compression case and having a discharge fan, the paper dust is sucked by the discharge fan. Furthermore, it is possible to obtain a mass of fine fiber pieces, and to increase the unit price of collecting the fine fiber pieces.

  According to the invention described in claim 6, at the end of the compression case, there is a push for pressing and dropping the fiber fragment solidified product compressed and solidified in the compression case downward from the compression case. By arranging the drop and drop device, when the fiber fragment solidified material piles up in the storage box and stays in the storage box and cannot be dropped, the fiber drop solidified material is forcibly pushed by the push and drop device. It is possible to break down the fiber fragment solidified product that has been pushed down and piled up in the storage box so that the fiber fragment solidified product can fall into the storage box. Therefore, there is an effect that it can be dropped and stored one after another in the storage box.

  An embodiment of the present invention will be described below with reference to the drawings.

  First, a waste paper storage case, a transport mechanism, and a shredding device of a shredder device provided with a compression-solidifying device will be described with reference to FIG.

  Here, as an example of the shredder apparatus, a shredded shredder apparatus that shreds waste paper as fiber strips by shredding action will be described.

  As shown in FIG. 1, on the upper side of the compression-solidification device 6 in the shredder device for fiber strips according to the present embodiment, waste paper for storing a main body casing 2 and waste paper as fiber strips. A storage case 3, a transport mechanism 4 for transporting waste paper to a shredding processing unit, and a shredding device 5 for shredding waste paper.

  The fiber strip compression-solidifying device 6 according to the present embodiment will be specifically described with reference to FIGS.

  As shown in FIG. 2, the fiber strips that have been chopped into pieces by the shredding and crushing device 5 are compressed by the compression-solidifying device 6 and solidified into a fixed volume and a constant weight. It becomes a piece.

  As shown in FIGS. 2 to 4, the compression-solidifying device 6 connected to the discharge port of the shredding and crushing device 5 has a rotating shaft 132 mounted on a holding plate at the end of a rectangular conveyance case 131 having a rectangular cross section. A linear spiral screw 133 mounted with a fixed space formed on the outer periphery of the rotating shaft 132, a spiral blade body 134 connected to the transport tip, and a compression device 135 provided in the traveling direction. It is configured. The linear spiral screw 133 has a distal end as a free end so that fiber strips do not stay at the distal end.

  As shown in FIG. 4, the base case-side bottom surface 151 of the transport case 131 is provided with a paper dust filter discharge fan 152 that opens a window 159 fitted with a paper dust filter so as to suck the paper dust. I have to. That is, the paper dust generated in the shredding and crushing device 5 is sucked by the paper dust filter of the compression-solidifying device 6 so that the paper dust is adsorbed on the surface of the paper dust filter. Since it is removed while adhering to the transported fiber strip, it is prevented from scattering to the outside of the shredder, and paper dust that adheres to the paper dust filter is always removed by the transported fiber strip, thus reducing the maintenance load. be able to. In the figure, reference numeral 152a denotes an exhaust duct of the exhaust fan 152. The exhaust duct 152a can discharge only air because paper dust is adsorbed on the surface of the paper dust filter. Reference numeral 152b denotes an exhaust vertical pipe that connects the window 159 and the exhaust duct 152a. For example, the paper dust filter may be composed of a 0.03 mm mesh wire mesh.

  The base end of the rotary shaft 132 is supported by a machine frame 139 located at the base end of the transport case 131, and the intermediate position of the rotary shaft 132 near the tip is supported by a holding plate 136 protruding from the machine frame. A conical cover 155 is attached to a part of the rotary shaft 132 before and after the holding plate 136 so that the fiber strips do not accumulate in the front and rear portions of the holding plate 136 around the rotary shaft 132.

  However, the fiber strips of the paper also stay on the end surface of the holding plate 136 while being transported in the distal direction by the spiral screw 133. In this way, even if a small amount of fiber debris stays, paper fiber debris and paper dust are gradually stacked on this part, causing paper jams, and finally the entire fiber debris is hindered. . Therefore, in order to scrape off the staying fiber pieces, a scraping scraping roller 117 that rotates upward is disposed at the final position of the discharge port of the shredding crushing device 5. It arrange | positions along the rotating shaft 132 of the helical screw 133, and the paper strip from the shredding crushing apparatus 5 is kept from staying in the boundary between the shredding crushing apparatus 5 and the compression-solidifying apparatus 6. The spiral screw 133 is divided into a front-stage screw 133a and a rear-stage screw 133b with a holding plate 136 interposed therebetween.

  The tip of the spiral blade body 134 has a surface parallel to the compression surface, and the spiral blade body 134 and the spiral screw 133 are formed so as to gradually increase the feed angle. 133b is configured to converge 360 degrees by rotating it twice, and the front screw 133a is configured to converge 360 degrees by rotating it twice.

  Here, the scraping roller 117 disposed above the transport case 131 will be specifically described.

  As shown in FIGS. 2, 3, 12, and 20, an opposing scraping roller shaft 118 is disposed below the third crushing shaft 103. Similarly to the third crushing shaft 103, the scraping roller shaft 118 also has a scraping roller gear 120 having a large number of sharpened teeth 119 protruding and a tooth receiving groove 121 formed on the circumferential surface in a circular shape. The four spacers 122 are alternately arranged in parallel, and the scraping roller gear 120 is loosely fitted with the tooth receiving groove 114 of the third spacer 115, and the tooth receiving groove 121 of the fourth spacer 122 is loosely fitted with the third crushing gear 113, respectively. Are facing each other. 125 is a tooth portion of the scraping roller gear 120, 112 is a tooth portion, and 116 is a tooth portion.

  According to the scraping roller 117, the rotating operation of the scraping roller gear 120 acts so as to scrape out the fine fiber clogged in the tooth receiving groove 114 of the third spacer 115, and above the compression-solidifying device 6. By scraping off the fiber strips accumulated at the ends of the fibers, accumulation and solidification of the fiber strips can be prevented. Further, the scraping roller 117 can evenly sweep the fiber pieces falling from between the second and third crushing gears 107 and 113 into the space in the compression-solidifying device 6.

  Next, a modified example of the transport case 131 will be described with reference to FIG. The modified example of the transport case 131 shown in FIG. 12 is given the same reference numerals as those in the transport case 131 shown in FIGS.

  FIG. 12 shows a state in which all of the front and rear stage screws 133 a and 133 b and the spiral blade body 134 are stored in the transport case 131, and the leading end surface of the spiral blade body 134 is positioned at the boundary between the transport case 131 and the compression case 137. Thus, the compression case 137 faces the opening 213.

  The bottom surface and part of the side surface in the transport case 131 have a recess 212 structure in order to obtain a constant transport area. The recess 212 is formed by the conical cover 155 in the front and rear stage screws 133a and 133b of the holding plate 136. It is provided at the mounting position. Accordingly, since the fiber strips transported by the front screw 133a in the transport case 131 have a transport area widened by the recess 212 without being narrowed by the conical cover 155, the fiber strip per unit area of the fiber strips. Can be made constant at all times, and the fiber strips can be smoothly fed into the transport case 131 by the recess 212 from the scraping roller 117 disposed obliquely above the transport case 131 in the compression-solidifying device 6. Can be transported.

  Next, a further modification of the transport case 131 will be described with reference to FIG. The modified example of the transport case 131 shown in FIG. 16 is assigned the same reference numeral as that in the transport case 131 shown in FIG.

  The transport case 131 shown in FIG. 12 has the discharge fan 152 disposed on the bottom surface of the transport case 131. However, the paper dust in the transport case 131 is provided on the bottom surface of the transport case 131 shown in FIG. The fan 152 is arranged at the bottom of the compression case 137. The discharge fan 152 sucks the paper dust in the transport case 131 from the window 159, passes the openings 137a and 137b, and then discharges the paper powder below the compression case 137.

  Next, the compression device 135 provided on the lower side of the transport case 131 will be described.

  A compression device 135 is connected to the front side of the spiral blade body 134. The compression device 135 includes a compression case 137 having front and rear openings, and a contact plate 138 provided so as to be freely inserted and removed inside the compression case 135. The upper, lower, left and right inner surfaces of the compression case 137 are widened tapered surfaces along the traveling direction of the fiber strip. The abutment plate 138 is interlocked and connected to an urging mechanism 140 placed outside the compression case 137, and is normally housed in the compression case 137 so that the inside of the box is closed. When a lump of material is applied as a constant compression load, it is compressed to become a fixed volume of fiber fragment solidified material, and finally pressed against the biasing plate 138 to the outside of the compression case 137 for compression. The inside of the case 137 is opened, and a fixed volume of fiber strip solidified product is extruded and discharged to the outside of the compression case 137 as it is. The urging mechanism 140 is attached to the abutment plate operating mechanism 130 and energizes the abutment plate 138 into the compression case 137. The abutment plate operating mechanism 130 supports the abutment plate 138 on an abutment plate shaft 145 erected on the outer side of the side wall of the compression case 137 and rotates the abutment plate 138 around the abutment plate shaft 145. The abutment plate 138 is moved back and forth from the slit 142 formed in the compression case 137 into and out of the compression case 137. This urging mechanism 140 is configured so that the urging force gradually decreases as the fiber strip is pressed against the abutment plate 138 by a spring 148 interposed between the operating base 158 of the abutment plate 138 and the energizing frame 160. Is done.

  The urging mechanism 140 will be described with reference to FIGS.

  As shown in FIGS. 4 and 6, upper and lower slits 142 for the abutment plate are formed on the side wall 141 of the compression case 137. In FIG. 5, the upper and lower plates 144 project from the outer wall 143 of the compression case 137.

  As shown in FIGS. 5 and 7, a contact plate shaft 145 is erected between the upper and lower plates 144, and as shown in FIGS. 7 and 8, the contact plate 138 is horizontally connected to the contact plate shaft 145. Then, the abutment plate 138 rotates around the abutment plate shaft 145 to enter and exit the compression case 137 through the abutment plate slit 142.

  As shown in FIGS. 7 and 8, a vertical axis 146 is inserted into the extended portion of the abutment plate 138, and three upper and lower spring receiving protrusions 147 are connected to the vertical axis 146, and the protrusion 147 is provided. A spring 148 is interposed between one end of the spring and a biasing frame 160 located at the base end of the compression case 137. In FIG. 5, reference numeral 149 denotes a spring receiving portion of the urging frame 160.

  Accordingly, as shown in FIGS. 7 to 11, in the normal compression initial stage, the abutment plate 138 is rotated about the longitudinal axis 146 by the urging force of the spring 148 and is pushed into the compression case 137. In the compression case 137, a fixed-volume fiber strip of paper pieces is compressed and abuts against the contact plate 138. In this state, the paper chunks are successively pumped, and a certain amount of the fine fiber pieces of paper are blocked and retained by the contact plate 138, and a certain hardness is generated in the paper chunk. In FIG. 10 and FIG. 11, when the hardness becomes more than a certain level due to the subsequent feeding of the paper piece, the pressing plate 138 is released in the opening direction against the urging of the spring 148 by the pressure of the paper piece. 137 rotates outside. In FIG. 11, when the abutment plate 138 is released to a certain position and displaced, the urging force of the spring 148 decreases due to the positional relationship between the fulcrum A and the action points B and C, and the final opening operation of the abutment plate 138 is facilitated. Prompt. When the fiber strip solidified product is discharged from the compression case 137, the force applied to the contact plate 138 in the compression case 137 disappears, and the contact plate 138 returns to the original state by the urging force of the spring 148.

  Eventually, the abutment plate 138 rotates around the abutment plate shaft 145 against the bias of the spring 148 and moves out of the abutment plate slit 142 to the outside of the compression case 137 to open the inside of the compression case 137. A fixed volume of fiber strip solidified product is extruded and discharged to the outside of the compression case 137 as it is. In this case, the biasing force of the spring 148 is adjusted by the positional relationship between the abutment plate shaft 145, the vertical axis 146, and the spring receiving portion 149 of the biasing frame 160.

  That is, in the compression case 137, a fixed-volume fiber strip of paper is compressed and abutted against the abutment plate 138, and finally the abutment plate 138 resists the bias of the spring 148 to cause the abutment shaft 145 to move. In the process from turning to the center and moving out of the abutment plate slit 142 to the outside of the compression case 137, the urging force of the spring 148 decreases as the end of the abutment plate 138 moves out of the compression case 137 in the final stage. It is configured. This is because the abutting plate 138 is smoothly withdrawn so that the inside of the compression case 137 is easily opened so that the fiber fragment solidified product is easily released from the compression case 137. Further, in order to facilitate release of the fiber fragment solidified product from the compression case 137, a plate 161 having a thickness reduced toward the outside is disposed on the upper, lower, left and right side walls 141 of the compression case 137, As the strip solidified product slides on the plate 161 and approaches the outside of the compression case 137, the pressure from the plate 161 is lowered so that it is easily discharged. In FIG. 7, connecting shafts 150 and 150 are provided so that upper and lower contact plates 138 and 138 are integrally operated.

  Next, a pressing and dropping device is provided above the compressing device to press the paper pieces downward, and will be specifically described below.

  A vertical cylinder 210 is connected in communication with the terminal opening of the compression case 137 for dropping a piece of paper, which is a solid fiber fragment extruded from the compression case 137, downward. Below the vertical cylinder 210, a storage box 211 for storing paper chunks is disposed. A push-down device 200 is provided above the vertical cylinder 210. When the paper lump is piled up in the storage box 211 and stays in the vertical tube 210 and cannot be dropped, the push-down device 200 The paper chunks are forcibly pushed down to break up the piled paper chunks in the storage box 211 so that the paper chunks can fall into the storage box 211.

  The push-down device 200 includes a press rod 201 provided so as to be movable up and down above a vertical cylinder 210, a spring 202 that is attached to the press rod 201 and urges the press rod 201 upward, and an upper end of the press rod 201. And a contact plate 204 provided continuously to the lower end of the press rod 201.

  Therefore, when the paper chunk stays in the vertical cylinder 210, when the press button 203 is pressed with a finger, the press rod 201 descends against the bias of the spring 202 and the paper chunk stayed in the vertical cylinder 210 is removed. By pushing down through the contact plate 204, the piles of the paper chunks piled up in the storage box 211 below it are broken to facilitate the fall of the paper chunks.

  In addition, a detection plate 205 is pivotally supported in a suspended state at the upper end inside the vertical cylinder 210 at a position opposite to the direction in which the paper chunks are horizontally discharged from the compression case 137. When the paper block that cannot fall is retained, the retained paper block is pushed by the succeeding paper block, and the detection plate 205 positioned in front of the paper block is rotated about a fixed angle around the pivoting portion 206. Then, it is brought into contact with the sensor 207 disposed near the end of rotation. That is, a state in which the paper piece is pressed against the upper portion of the vertical cylinder 210, in other words, a state in which the paper piece is retained in the vertical cylinder 210 is detected and notified.

  When the press button 203 is manually pressed after receiving the notification of the staying state of the paper piece, the staying paper piece is pressed downward through the press rod 201 and dropped into the storage box 211.

  In this way, the vertical cylinder 210 provided with the push-down device 200 not only guides the block of paper discharged from the compression case 137 into the storage box 211 but also a sensor disposed in the upper part of the vertical cylinder 210. It is also possible to perform a function of detecting and reporting a paper lump that cannot be dropped by 207 and forcibly pushing down and dropping by the push-down device 200. In addition to the manual type, the push-down device 200 can be automated by driving a motor based on a signal from the sensor 207 and pushing down the vertical cylinder 210 downward.

  Next, another embodiment of the compression device 135 will be described in detail with reference to FIGS. About the structure of the compression apparatus 335 of another Example, the duplication description is abbreviate | omitted by attaching | subjecting the same code | symbol as the structure of the compression apparatus 135. FIG.

  This embodiment is characterized in that the position of the spring 148 for biasing the abutting plate 138 in the above-described embodiment is arranged on the opposite side.

  That is, in this embodiment, as shown in FIGS. 13 to 15, a spring 148 is interposed between the abutment plate 138 and a spring receiving portion 149 provided on the lower discharge side of the paper piece, and FIG. The spring receiving portion 149 has three upper and lower portions on a vertical plate 362 interposed between upper and lower projecting plates 361 that are stretched on the upper and lower plates of the compression case 137. 8 to 11, a spring 148 is interposed between the spring receiving portion 149 and the upper and lower three spring receiving protrusions 147 projecting on the longitudinal axis 146 of the plate 138. It is configured to perform the same spring function.

  By adopting such a spring position configuration, after receiving the paper piece of the fine fiber piece by the abutting plate 138 and entering the compressing operation to complete the compression of the paper piece, the abutting plate resists the bias of the spring 148. When 138 begins to move away, the urging force is reduced at a stroke, the contact plate 138 is opened, and the compressed paper block is discharged. Compared with the spring function of FIGS. The spring length can be made longer in the position of the spring in this embodiment. Therefore, the effect of reducing the urging force when the abutment plate 138 is moved out can be increased by the length of the spring, and the repeated increase / decrease of the urging force that is likely to occur at the initial stage of the urging force reduction can be prevented. In other words, there is an effect that the compression strength of the fiber strip having a certain hardness can be obtained by preventing the compression strength of the fiber strip to the paper chunk.

  The upper and lower projecting plates 361 are formed in a bifurcated bifurcated shape with the projecting tip portions having the same upper and lower shapes. The upper and lower branch tip portions are connected to the vertical plate 362, and the vertical plate 362 is connected to the spring base. A spring receiving portion 149 whose end is locked is formed. Accordingly, the distance between the spring receiving portion 149 and the spring receiving protrusion 147 to which the spring tip is locked can be increased, and the spring length is increased correspondingly, and the aforementioned increase / decrease in the biasing force is repeated. Can be prevented.

  Further, the overhang plate 361a forms a top plate of the vertical cylinder 210, and the above-described insertion hole 208 for raising and lowering the press rod 201 is formed in the center thereof. Therefore, the push-down device 200 is provided on the upper projecting plate 361a.

  Next, another embodiment of the compression device 135 will be described in detail with reference to FIGS. Further, the configuration of the compression device 435 according to another embodiment is denoted by the same reference numeral as that of the configuration of the compression device 135, and a part of the description is omitted.

  The present embodiment is characterized in that the position of the abutment plate 138 in the above-described embodiment is positioned above the compression case 137. That is, as shown in FIGS. 16 and 17, the compression device 435 according to the present embodiment has a front opening and a semicircular arc-shaped compression case 137 at the rear, and two left and right abutment plates on the ceiling wall of the compression case 137. The slits 142 and 142 are formed, and the abutment plate 138 is disposed in the abutment plate slit 142 so as to freely advance and retract. A leaf spring 440 is disposed on the bottom wall 441 of the compression case 137 so as to warp from the proximal end toward the distal end.

  Specifically, an urging frame 160 is separately provided on the upper portion of the compression case 137, and an abutment plate shaft 145 is horizontally mounted on the lower portion of the urging frame 160. The shafts 145 are fixed to the bases of the left and right abutting plates 138, 138 so as to be rotatable upward. The left and right abutting plates 138, 138 are formed in a substantially vertical shape so as to receive a piece of paper at the front edge, and a horizontal axis 446 is pivoted behind the abutting plate shaft 145 so that the horizontal axis 446 A spring receiving projection 147 is provided continuously, and a spring 148 is interposed between one end of the projection 147 and the biasing frame 160. In the figure, 149 is a spring receiving portion of the urging frame 160, and 450 is a long hole through which the horizontal shaft 446 rotates.

  Further, left and right abutting plates 138, 138 are interposed by connecting shafts 150 at the rear portions of the left and right abutting plates 138, 138.

  In the compression device 435 configured as described above, the pressing plates 138 and 138 are always housed in the compression case 137 in conjunction with the urging mechanism 140 including the spring 148, and the upper half of the compression case 137. However, when the fiber strip lump is applied to the abutting plates 138 and 138 as a constant compression load, it is compressed to become a fixed volume of fiber fragment solidified product. The pressing plate 138 is pushed outside the compression case 137 against the urging force to open the inside of the compression case 137, and a fixed amount of the fiber fragment solidified product is discharged as it is from below the compression case 137. The urging mechanism 140 is attached to the abutment plate operating mechanism 130 and energizes the abutment plate 138 into the compression case 137. The abutment plate operating mechanism 130 supports the abutment plate 138 on an abutment plate shaft 145 disposed on the ceiling wall of the compression case 137 and rotates the abutment plate 138 around the abutment plate shaft 145 to compress the compression case. The abutment plate 138 is moved forward and backward from the slit 142 formed in the 137 into and out of the compression case 137. This urging mechanism 140 is configured so that the urging force gradually decreases as the fiber strip is pressed against the abutment plate 138 by a spring 148 interposed between the operating base 158 of the abutment plate 138 and the energizing frame 160. Is done.

  Accordingly, as shown in FIG. 17, in the normal initial stage of compression, the abutment plate 138 is rotated about the horizontal shaft 446 by the urging force of the spring 148 and is pushed into the compression case 137. Within 137, a fixed volume of fiber strips of paper are compressed and abut against the abutment plate 138. In this state, the paper chunks are successively pumped and a certain amount of fiber strips are blocked by the abutment plate 138 and retained, and a certain degree of hardness is generated in the paper chunks. When the hardness becomes more than a certain level due to the subsequent feeding of the paper piece, the pressing plate 138 is rotated in the opening direction against the bias of the spring 148 by the pressure of the paper piece, that is, outside the compression case 137. Go. When the contact plate 138 is released to a certain position and displaced, the urging force of the spring 148 decreases due to the positional relationship between the fulcrum A and the action points B and C, and the final opening operation of the contact plate 138 is facilitated. When the fiber strip solidified product is discharged from the compression case 137, the force applied to the contact plate 138 in the compression case 137 disappears, and the contact plate 138 returns to the original state by the urging force of the spring 148.

  Eventually, the abutment plate 138 rotates around the abutment plate shaft 145 against the bias of the spring 148 and moves out of the abutment plate slit 142 to the outside of the compression case 137 to open the inside of the compression case 137. A fixed volume of fiber strip solidified product is extruded and discharged to the outside of the compression case 137 as it is. In this case, the biasing force of the spring 148 is adjusted by the positional relationship between the abutment plate shaft 145, the horizontal shaft 446, and the spring receiving portion 149 of the biasing frame 160. The leaf spring 440 disposed in the compression case 137 pushes the fiber strip upward to abut against the contact plates 138 and 138 in an initial state where the fiber strip transported from the transport case 131 is small. It is easy. When a large amount of fiber strips are conveyed and the compression action starts, the tip of the leaf spring 440 comes into contact with the bottom wall 441.

  That is, in the compression case 137, a fixed-volume fiber strip of paper is compressed and abutted against the abutment plate 138, and finally the abutment plate 138 resists the bias of the spring 148 to cause the abutment shaft 145 to move. In the process from turning to the center and moving out of the abutment plate slit 142 to the outside of the compression case 137, the urging force of the spring 148 decreases as the end of the abutment plate 138 moves out of the compression case 137 in the final stage. It is configured. This is because the abutting plate 138 is smoothly withdrawn so that the inside of the compression case 137 is easily opened so that the fiber fragment solidified product is easily released from the compression case 137. Further, in order to facilitate release of the fiber fragment solidified product from the compression case 137, plates 161, 161 having a thickness reduced toward the outside are disposed on the left and right side walls 141, 141 of the compression case 137. However, as the fiber strip solidified product slides on the plate 161 and approaches the retreating of the compression case 137, the pressure from the plate 161 is lowered and easily discharged. Furthermore, since the back of the compression case 137 has a semicircular arc shape, the fiber fragment solidified product is discharged downward without staying in the compression case 137.

A piece of paper discharged from the lower side of the compression case 137 is discharged to the opening 401 on the upper surface of the table 400 shown in FIG. 19, and placed in the table 400 through a funnel-shaped discharge pipe 402 connected to the opening 401. It is discharged above the trash bin 410 placed. On the upper surface of the table 400, a rectangular recess 403 for storing a clip and an opening 404 for storing a paper cup 405 for storing a used stapler blade are formed. Reference numeral 408 denotes moving casters disposed at the four corners of the table 400.
In the compression-solidifying device 6 configured as described above, the shredder crushing device 5 is disposed on the upper side, and the shredder crushing device 5 uses waste paper as shredded fiber strips as will be described later. Therefore, since the compression action is finally performed in the compression device while being compressed and conveyed in the conveyance case 131 in the compression-solidifying device 6, the effect of compressing the fiber pieces unique to the present invention as described below is provided. Will be described in detail.

  In other words, the fiber strips of the shredded fiber are in a state where the fibers are exposed, and the fiber strips are easily entangled with each other due to wrinkles, and the fiber strips are compressed compared to the conventional strips having a clean cut surface. For example, after 1000 sheets of A4 size waste paper are drawn and shredded and then compressed and solidified, they are solidified to 10 to 16 liters. That is, conventionally, fiber fragments that have not been compressed and solidified could only be loaded on a 4-ton vehicle for about 0.2 tons due to volume expansion, but fiber fragments that have been compressed and solidified by the compression and solidification apparatus of this embodiment. In the case of a solidified product, the maximum loading capacity of 4t can be loaded on a 4t vehicle, which has the effect of improving transportation efficiency.

  As described above, in the paper block obtained by compressing and solidifying the fiber strips that are shredded, the fiber strips of the randomly shaped paper are folded and solidified, so that reproducibility is difficult and confidentiality can be improved.

  That is, since the waste paper is made into fiber strips torn by the shredder crushing device 5 and sent to the compression-solidifying device 6, it is easier to compress than the conventional strips, and easily converted into fiber-stripe solidified products. Can be discharged.

  For example, when the spiral screw 133 disposed on the rotating shaft 132 is formed integrally with the rotating shaft 132 and has no gap, when trying to transport a large amount of shredded fiber strips, Due to the peculiar properties of the pieces, the fine fiber pieces are entangled like cotton and twisted with the rotating spiral screw 133, so that there is a possibility of staying in one place without being conveyed. However, in the linear spiral screw 133 of the compression-solidifying device 6 according to the present embodiment, it is possible to prevent the fiber strips from rotating and improve the conveyance efficiency in the rotation axis direction. According to the compression-solidifying device 6 according to the present embodiment, by making the helical screw 133 as thin as possible, it is in line contact with the shredded fiber strip and in contact with the surface in the transport case 131. On the other hand, it becomes difficult to entangle, and the rotational torque of the rotating shaft 132 can be easily converted into a conveying force.

  In such a configuration, even when the fiber strips are entangled like cotton (bridged), the bridge-shaped fiber strips can be transported together, so that the thin spiral screw 133 can transport efficiently. it can.

  Furthermore, by making the cross section of the above-mentioned transport case 131 into a quadrangular shape, it is possible to further prevent the fiber strips from being twisted. Since the rotary shaft of the spiral screw 133 is configured to be supported at two points, and the scraper roller 117 is further disposed on the upper side to scrape the fiber strips, accumulation and solidification of the fiber strips can be prevented. With such a configuration, even if the compression pressure is increased, noise such as metal sound caused by a pivoted portion or the like can be prevented. In other words, with this configuration, stick slip on the compression surface can be prevented and generation of metal sound can be prevented. For example, it is preferable to use stainless steel as the material of the linear spiral screw in order to obtain strength.

  According to such a configuration, it is possible to efficiently compress and solidify the fiber strips with only a small rotational power obtained from the drive motor 78, and it is possible to reduce the size of the compression mechanism. Moreover, since the aging which is a post-process after compressing the fiber strip is not required, that is, the aging discharge path is unnecessary, the apparatus can be miniaturized and the cost can be reduced. Note that aging refers to applying a preload for a while after compression in a fiber block of fiber pieces that has been hardened with a weak compression force, because if the compression force is released immediately, it will return to the volume before compression. Say.

With this configuration, the conveyance efficiency can be increased, the cross-sectional area of the compression case can be halved, and the pressure per unit area can be doubled.
Next, the waste paper storage case 3, the transport mechanism 4, and the shredder / crusher 5 up to the compression / solidification device 6 will be specifically described.

  A waste paper storage case 3 for storing waste paper is provided on the upper side of the compression-solidifying device, and the waste paper storage case 3 will be described below with reference to FIGS. 1, 21, and 22.

  As shown in FIGS. 1, 21, and 22, the waste paper storage case 3 includes a lid body 10 and an auxiliary cradle 11 that cover the conveyor belt 9.

  The lid 10 and the auxiliary cradle 11 can be expanded or contracted according to the size of the waste paper. In this embodiment, the lid 10 and the auxiliary cradle 11 support two types of A4 size and A3 size, but B5 and B4 sizes are also available. Storage processing is possible in A4 size and A3 size.

  The lid body 10 is configured to be capable of closing the upper portion of the waste paper stacked on the conveyor belt 9 in a sealed manner, and is formed in a rectangular box shape that is open downward. Is pivotally supported on the front upper side wall of the main casing 2 so that the lid 12 can be opened and closed with the pivotal support 12 as the center. Reference numeral 51 denotes a drive shaft 51 that gives rotational power to the conveyor belt 9, and reference numeral 52 denotes an idle shaft 52 that is linked to the drive shaft 51 via the conveyor belt 9.

  Moreover, the auxiliary lid 13 for expansion and contraction is stored inside the lid 10 so as to overlap with each other, and the auxiliary lid 13 is also formed in a box shape that is open downward like the lid 10.

  Moreover, by pulling out the auxiliary lid 13 from the end of the lid 10, the lid 10 changes to an elongated form, and can cover the upper side of the large-sized waste paper.

  As shown in FIG. 1 and FIG. 22, convex protrusions 16, 16 are provided at two locations on the outer end surface of the auxiliary lid 13. The projecting pieces 16, 16 engage with the openings 17, 17 on the upper surface side of the base end of the main casing 2 or the openings 18, 18 on the terminal surface of the auxiliary cradle 11.

  As shown in FIGS. 1 and 21, on both side walls of the auxiliary lid 13, convex protrusions 19, 19 are formed at two locations in the middle, and convex shapes are formed at two locations in the vicinity of the base end side of the main body casing 2. Protrusions 20, 20 are provided.

  When the auxiliary lid 13 is in a contracted state, the projecting pieces 20 and 20 on the base end side on both side walls engage with the openings 21 and 21 on both sides of the upper surface of the main casing 2 as shown in FIG.

  Further, when the auxiliary lid 13 is pulled out, as shown in FIGS. 21 and 22, the projecting pieces 20, 20 on the base end side on both side walls of the auxiliary lid 13 are on the both sides of the surface of the auxiliary cradle 11. In addition to engaging with the openings 22, 22, the projecting pieces 19, 19 in the middle of the both side walls of the auxiliary lid 13 engage with the openings 21, 21 on both sides of the upper surface of the main body casing 2.

  Further, as shown in FIG. 21, a first engaging member 14 made of irregularities is provided between the distal outer surface of the auxiliary lid 13 and the inner inner surface of the lid 10. Between the midway part and the base end inner side surface of the lid body 10, second engaging members 15 each having an unevenness are provided. The first engaging member 14 includes a first convex portion 23 and a first concave portion 24, and the second engaging member 15 includes a second convex portion 25 and a second concave portion 26.

  The lid 10 and the auxiliary lid 13 are provided with a mechanism for expanding and contracting the auxiliary lid 13.

  Thus, by providing a mechanism for extending and retracting the auxiliary lid body 13, the lid body 10 and the auxiliary lid body 13 can be slidably expanded and contracted, and the auxiliary lid body 13 can be held.

  Next, the structure of the auxiliary cradle 11 will be described.

  As shown in FIGS. 1, 21, and 22, the auxiliary cradle 11 is used when processing large-sized waste paper. The auxiliary cradle 11 extends the auxiliary lid 13 from the lid 10 and covers the lid 10 and the like. In order to support the large-sized waste paper that protrudes behind the position of the conveyance belt 9 when covering the large-sized waste paper, the paper is projected and attached to the rear side of the conveyance belt 9. For example, large size waste paper is A3 size and B4 size.

  The auxiliary cradle 11 is pivotally supported at the tip by a pivotal support 30 provided on the rear side wall of the main casing 2 and is configured to be bent in the vertical direction.

  When processing small-sized waste paper, the small-size waste paper is accommodated on the conveyor belt 9, so that the auxiliary receiving base 11 is unnecessary. In this case, the paper is bent downward from the pivotal support 30 and stored vertically. Leave it in the state. For example, small size waste paper is A4 size and B5 size.

  When processing large-sized waste paper, the paper is displaced in the horizontal direction around the pivotal support portion 30 and protrudes from the rear of the conveying belt to support the large-sized waste paper.

  A lock mechanism 36 is interposed between the distal end portion of the auxiliary cradle 11 and the side wall of the main casing 2.

  That is, when the auxiliary cradle 11 is set in a horizontal state when processing large-sized waste paper, if the lock mechanism 36 does not act on the auxiliary cradle 11, the auxiliary cradle 11 is forcibly folded in the vertical direction. In other words, large waste paper that protrudes behind the conveyor belt is exposed.

  In this state, if the waste paper exposed from above the folded auxiliary cradle 11 is pulled out, it may not meet the purpose of crushing the waste paper for confidentiality, and secret leakage may occur from the waste paper.

  In order to prevent such an unexpected situation, when the auxiliary cradle 11 is set in a horizontal state for large-size waste paper processing, when the lid 10 and the auxiliary lid 13 are closed together, the auxiliary lid 13 The projecting piece 19 or the projecting piece 20 activates the lock mechanism 36, and the lock mechanism 36 of the auxiliary cradle 11 is automatically activated.

  In such a state, the auxiliary cradle 11 cannot be bent due to an external factor, and is not in a stored state. Accordingly, it is impossible to draw out large-sized waste paper carelessly, and the purpose of maintaining confidentiality can be sufficiently achieved.

  Between the side wall of the auxiliary lid 13 and the side wall of the main body casing 2, that is, the side wall of the waste paper storage space on the conveyor belt 9, as shown in FIGS. 44 is interposed.

  That is, when the lid is closed and the lock pin 45 provided on the side wall of the main body casing 2 is advanced and retracted by the solenoid 46, the lock pin 45 and the side wall of the auxiliary lid 13 are engaged or detached and the lid body is released. Ten open / close locks are made. The auxiliary lid 13 is provided with two pin holes 47 at the front and rear, and the lock pin 45 can be engaged with the auxiliary lid 13 when the auxiliary lid 13 is housed and extended. is doing.

  The electric operation of the lock pin 45 is performed by an operation switch 48 provided separately, and the operation switch 48 is configured so that it cannot be operated unless a predetermined operation key 8 is used.

  As described above, the switch operation is performed using the predetermined operation key 8 so that the cover is inadvertently closed during the waste paper processing so that the waste paper cannot be removed.

  In addition, on the inner bottom surface of the waste paper storage space 7, a regulating plate 49 is erected while maintaining a certain gap from the inner wall surface, and both side walls of the lid 10 are disposed at the waste paper storage space 7 during the closing operation. It is comprised so that it may fit in the clearance gap between the inner wall surface and the control board 49. FIG.

  That is, even if both side walls of the lid 10 are inadvertently pressurized inward from the outside, the lid locking mechanism is interposed between the main body casing 2 so as not to be displaced inward by the restriction plate 49. 44 inadvertent release is not caused.

  Next, another embodiment of the waste paper storage case 3 will be specifically described with reference to FIG.

  The waste paper storage case 3 is formed with a curved portion 2 a that protrudes upward in a curved shape in a side view when the base end of the main body casing 2 is formed, and the cover 10 covers the upper portion of the conveyor belt 9. For example, when a long A3 waste paper is placed in the waste paper storage case 3, the rear end of the waste paper is bent upward along the curved portion 2a. It can be shortened. A protruding piece 20 that engages with the opening 17 on the upper surface side of the base end of the main casing 2 is provided on the outer surface of the front end of the lid 10 so that it can be locked.
