Description

  The present invention relates to a scrap compressing apparatus for compressing a scrap formed by collecting wastes and the like to a desired size, and a method thereof.

  FIG. 13A shows a pair of side walls 41, 51 facing each other, an end wall 61 crossing between the pair of side walls 41, 51, a pressing slide 7 facing the end wall 61, and an end wall 61. The horizontal pressing slide 8 is shown. After the scrap 14 is put into the concave portion 13 surrounded by these elements and the upper surface of the base not shown in the drawing, the concave portion 13 is closed by a push lid overlying it.

  In this state, the scrap 14 can be compressed toward the end wall 61 by the pressing slide 7 moving forward in the direction indicated by the arrow X as shown in FIG. In this process, when the pressing slide 7 approaches the end wall 61 and the distance between them decreases to a dimension T substantially equal to the width of the lateral pressing slide 8, the pressing slide 7 stops. For example, when the pressing slide 7 is operated using a hydraulic cylinder, the pressing slide 7 stops as described above at the position where the stroke limit of the extension of the piston rod of the hydraulic cylinder is reached.

Subsequently, as shown in FIG. 5C, the side press slide 8 moves forward in the direction indicated by the arrow Y, whereby the scrap 14 between the press slide 7 and the end wall 61 is moved to one side wall. The scrap 14 can be compressed into a rectangular block by compressing from 41 toward the other side wall 51.

  As described above, as the laterally-pressing slide 8 moves forward in the direction indicated by the arrow Y, the scrap 14 is directly pushed by the laterally-pressing slide 8 at the end 141 in contact with the laterally-pressing slide 8. For this reason, the vicinity of the end portion 141 is compressed well, and the metal pieces and scraps contained in the scrap 14 are in a close state in close contact with each other.

  However, the vicinity of the end 142 in contact with the other side wall 51 of the scrap 14 is in a rough state in which voids are left between metal pieces or scraps included in the scrap 14 and compression is not sufficient. This is because the friction between the scrap 14 and the pressing slide 7 and the friction between the scrap 14 and the end wall 61, the base, and the press cover are excessively increased in the process in which the lateral pressing slide 8 moves forward. The problem is that the force with which the slide 8 presses the end portion 141 of the scrap 14 is not transmitted to the end portion 142.

  The lump of scrap 14 illustrated in FIG. 13C is a rectangular parallelepiped having a side of 600 mm. This is a standard established with the intention of putting the scrap 14 into the electric furnace. However, due to the above problems, the size of the lump of scrap 14 may not fit within the above standards. In this case, the direction of the both ends 141 and 142 of the scrap 14 is reversed, and the time and effort of performing the compression by the laterally pressing slide 8 again is forced. Alternatively, in the method of reducing the size of the scrap 14 by cutting the lump of the scrap 14 or intentionally reducing the amount of the scrap 14 to be put into the trouble recess 13 at a time, the efficiency of processing the scrap 14 is reduced. Decreases.

  Therefore, the present invention has been made in view of the above circumstances, and the object of the present invention is to provide a scrap compressing device capable of preventing defective compression of scrap due to unnecessary friction in the process of compressing scrap, and its It is to provide a method.

  The present invention includes a pair of side walls facing each other on a base and having one end and the other end, an end wall crossing between one end of each of the pair of side walls, and each of the pair of side walls facing the end wall. A push slide that advances or retreats from the other end of the pair toward the end wall, a lateral slide that moves close to the end wall and advances or retreats from one of the pair of side walls to the other side wall, and A base, a pair of side walls, the end walls, and a pressing lid that opens and closes a recess surrounded by the pressing slide, and the pressing lid closes the recess in a state where scrap is put into the recess, As the push slide advances, the scrap is compressed toward the end wall, and a predetermined position is maintained that allows a minimum distance between the push slide and the end wall to allow the lateral push slide to pass. , The pushing slide stops, In the scrap compressing apparatus, wherein the lateral pressing slide advances through between the pressing slide at the specified position and the end wall, the scraping press compresses the scrap toward the other side wall. Detecting means for detecting the position of the pressing slide in a forward or backward stroke, and control means for controlling the operation of the pressing slide based on the position of the pressing slide detected by the detecting means, Scrap compression, wherein the control means turns the pushing slide backward at a position further advanced from the specified position, and stops the pushing slide when the pushing slide is moved back to the specified position. It concerns the device.

  Further, the present invention is surrounded by a pair of side walls facing each other on the base and having one end and the other end, an end wall crossing between each end of the pair of side walls, and a pressing slide facing the end wall. In the process of compressing the scrap, the scrap is thrown into the recessed portion, and the recessed portion is closed with a pressing lid overlying the recessed portion, and the pressing slide is advanced toward the end wall. Is turned backward at a position further advanced from a specified position that can maintain a minimum gap between the pressing slide and the end wall to allow passage of the lateral pressing slide, and the pressing slide is moved to the specified position. When retracted to a position, the pressing slide is stopped, and the lateral pressing slide passes between the pressing slide at the specified position and the end wall, and from one of the pair of side walls to the other side wall. By advancing toward, those of the scrap compression method characterized by compressing the scrap.

  According to the present invention, scrap is put into the recess surrounded by the base, the pair of side walls, the end wall, and the pressing slide, and the pressing slide is placed in a state where the recess is closed by the pressing lid that overlaps the scrap. By moving forward, the scrap can be compressed towards the end wall. In this process, the push slide moves forward after passing the specified position. The specified position means that there is a pressing slide at a position where a minimum interval allowing the passage of the lateral pressing slide remains between the pressing slide and the end wall.

  Furthermore, when the pushing slide turns backward and returns to the specified position, it stops. For this reason, a moderate space | gap can be ensured between the scrap compressed toward the end wall as described above and the pressing slide returned to the specified position.

  Subsequently, the side pushing slide passes between the pushing slide at the specified position and the end wall and advances from one of the pair of side walls toward the other side wall, whereby scrap is moved to the other side wall. Can be compressed towards. In this process, since the scrap and the pressing slide are not in contact with each other at first, there is no friction between the scrap and the pressing slide immediately after the pressing slide advances. Then, as the lateral slide slides forward, the width of the scrap expands, and the friction force between the two gradually increases as the scrap comes into contact with the thrust slide, but before the friction force increases, It can be compressed to the desired dimensions.

  Therefore, according to the present invention, the friction between the scrap and the pressing slide can be suppressed to a minimum and the scrap can be uniformly compressed, so that the size of the finally scraped scrap can be set as desired. For this reason, the lump of scrap can be processed without the need for inversion, recompression, or cutting. Moreover, since it is not necessary to take measures to intentionally reduce the lump of scrap, a large amount of scrap can be processed efficiently.

  In the following, the same designations or the same reference numerals are used for the elements already described as the prior art, and the respective illustrations or explanations are omitted. The term “cylinder” means an actuator such as a hydraulic cylinder that moves the piston rod back and forth.

  1-3, the scrap compression apparatus 1 which faces each other and has a pair of side wall members 4 and 5 having one end 2 and the other end 3, and an end wall crossing between one end 2 of each of the pair of side wall members 4 and 5 A member 6, a pressing slide 7 that faces the end wall member 6 and moves forward or backward from the other end 3 of each of the pair of side wall members 4 and 5 toward the end wall member 6; A side-push slide 8 that moves forward or backward from the side wall member 4 toward the other side wall member 5, and a push lid 9. Furthermore, the scrap compression apparatus 1 includes a detection unit 10 and a control unit 11 shown in FIG.

  1 and 2 and the end wall member 6 are provided on the upper surface of the base 12. On the upper surface of the base 12, the pair of side walls 41, 51 that are the inner surfaces of the pair of side wall members 4, 5, the end wall 61 that is the inner surface of the end wall member 6, and the recess 13 surrounded by the pressing slide 7. In this case, scrap 14 including metal pieces, scraps, and the like is input. One side wall member 4 is formed with an opening 42 through which the lateral push slide 8 passes, and the other side wall member 5 is formed with a discharge port 52 that is opened and closed by the gate slide 15. The gate slide 15 is connected to a piston rod of the gate cylinder 151, and can move to a position where the discharge port 52 is closed or retracted to the side of the discharge port 52 and the discharge port 52 is opened according to the expansion and contraction of the piston rod.

  The pressing slide 7 is connected to the piston rods of the two pressing cylinders 71. In the process in which the eaves slide 7 moves forward or backward according to the expansion and contraction of these piston rods, the eaves slide 7 and the pair of side walls 41 and 51, the eaves slide 7 and the lower surface of the push lid 9, and eaves A gap is maintained between the push slide 7 and the upper surface of the base 12 so that the scrap 14 cannot enter. The transverse push slide 8 is connected to the piston rod of the transverse push cylinder 81. In the process in which the lateral push slide 8 moves forward or backward in accordance with the expansion and contraction of the piston rod, there is a scrap between the lateral push slide 8 and the lower surface of the push lid 9 and between the lateral push slide 8 and the upper surface of the base 12. A gap to the extent that 14 cannot enter is maintained. The positional relationship among the end wall 61, the pressing slide 7 and the lateral pressing slide 8 will be described later.

  As shown in FIGS. 1 and 2, a bracket 91 is provided on the upper surface of the push lid 9, and a portal frame 92 is raised at the end of the base 12 opposite to the end wall member 6. The piston rod of the lid pushing cylinder 94 is connected to the bracket 93 in the middle of the longitudinal direction of the link 93 having the lower end pin joined to the bracket 91 and the upper end pin joined to the portal frame 92. Or take a posture to lie down horizontally. When the presser lid 9 stands up, the recess 13 is opened as shown in FIG. 1, and when the presser lid 9 is lowered, the recess 13 is closed.

  The detection means 10 shown in FIGS. 4 and 5 is a sensor that detects the position of the pressing slide 7 in the stroke in which the pressing slide 7 moves forward or backward. That is, the detecting means 10 measures the distance x by which the detected element 102 attached to the piston 72 of the pushing cylinder 71 is displaced along the sensing rod 103 as the piston 72 moves forward or backward. The distance x is converted into an electric signal indicating the position of the pressing slide 7 and transmitted to the control means 11 through the cable 101.

  The hydraulic pressure supply unit 16 shown in FIG. 4 includes a tank, a hydraulic pump, a direction switching valve, a safety valve, and piping, and supplies hydraulic pressure to the pushing (forward) side or retracting (reverse) side port of the push cylinder 71. To do. The control means 11 is mainly a computer, and can control the pump or the direction switching valve of the hydraulic pressure supply unit 16 based on a program written in a storage medium accessible by the computer or the electric signal.

  Further, the lateral pushing cylinder 81, the lid pushing cylinder 94 and the gate cylinder 151 are also supplied with hydraulic pressure from a hydraulic pressure supply unit not shown in the figure, and the pump or direction switching valve of this hydraulic pressure supply unit can also be controlled by the control means 11. For this reason, the control means 11 can operate the side pushing slider 8, the push lid 9, and the gate slide 15 in addition to the pressing slider 7 as follows.

  First, the push slide 7 and the lateral slide 8 retreat, and the gate slide 15 closes the discharge port 52. For example, as shown in FIG. 1, the scrap 14 is put into the concave portion 13 using a conveyor device such as a conveyor or a crane. When a certain amount of scrap 14 is put into the recess 13, the scrap 14 is cut off and the push lid 9 closes the recess 13. In this state, as shown in FIG. 2, the scraping slide 7 is advanced toward the end wall 61 (one end 2 in FIG. 2), so that the scrap 14 can be compressed toward the end wall 61.

  In this process, as shown in FIG. 6A, the pressing slide 7 moves forward until the distance between the pressing slide 7 and the end wall 61 becomes smaller than the dimension T substantially equal to the width of the lateral pressing slide 8. For example, it advances until the space | interval of the pressing slide 7 and the end wall 61 becomes 5 cm smaller than the dimension T. FIG. Further, the pressing slide 7 turns backward and stops when the pressing slide 7 returns to the specified position as shown in FIG. Thereby, the space | gap 17 can be ensured between the scrap 14 compressed toward the end wall 61, and the pressing slide 7 which returned to the defined position.

  Subsequently, as the laterally-pressing slide 8 advances toward the other side wall 51, the scrap 14 can be compressed toward the other side wall 51 as shown in FIG. In this process, as shown in FIG. 7 (a), the pressing slide 7 and the scrap 14 are not in contact with each other at the beginning, so immediately after the pressing slide 7 advances, the pressing slide 7 and the scrap 14 There is no friction between them. Then, as shown in FIG. 4B, the width of the scrap 14 expands as the lateral pressing slide 8 advances, and the scrap 14 comes into contact with the pressing slide 7 so that the frictional force between both increases gradually. However, before the frictional force increases, the scrap 14 can be compressed into a lump of a desired size.

  As described above, the distance between the pressing slide 7 and the end wall 61 at the specified position is slightly wider than the width of the lateral pressing slide 8. Further, the scrap 14 cannot enter the space between the end wall 61 and the laterally-pressing slide 8 and between the pressing slide 7 and the laterally-pressing slide 8 at the specified position in the travel of the laterally-pressing slide 8. The gap is maintained. The same applies to the case where the side push slide 8 moves backward.

  Finally, the gate slide 15 opens the discharge port 52, and the side push slide 8 further advances toward the other side wall 51 as shown in FIG. 8. Thereby, the lump of the scrap 14 can be discharged from the discharge port 52 to the outside of the other side wall member 5. The process described above is one cycle of the operation of the scrap compression apparatus 1. Reference numeral 14 ′ indicates a lump of scrap discharged from the discharge port 52 at the end of one cycle in which the scrap compression apparatus 1 has already been completed.

  The scrap compression apparatus 18 shown in FIGS. In the following, the same name or the same reference numeral is used for the same configuration as in the first embodiment, and the illustration or description thereof is omitted.

  The piston rods of the two lid pushing cylinders 94 are connected to the upper surface of the pushing lid 9, and the pushing lid 9 stands up or bends horizontally according to the expansion and contraction of these piston rods. The push slide 7 and the horizontal slide 8 are retracted, and the gate slide 15 closes the discharge port 52. As shown in FIG. 10, the push lid 9 closes the recess 13 into which the scrap 14 has been put. In this state, the scrap 14 can be compressed toward the end wall 61 by the advancement of the pressing slide 7. In this process, the distance between the pressing slide 7 and the end wall 61 becomes smaller than the width of the lateral pressing slide 8, and then the pressing slide 7 that has turned backward stops at the specified position as described above. is there.

  Subsequently, as shown in FIG. 11, the scrap 14 can be compressed toward the other side wall 51 by the advancement of the laterally pressing slide 8. The effects that can be achieved in this process are also as described above. Finally, the gate slide 15 opens the discharge port 52, and the side-pushing slide 8 further advances toward the other side wall 51, whereby the lump of scrap 14 is transferred from the discharge port 52 to the other side wall as shown in FIG. 51 can be discharged to the outside.

  According to the scrap compression devices 1 and 18 described above, the scrap 14 can be uniformly compressed by minimizing the friction between the pressing slide 7 and the scrap 14, so that the size of the lump of the scrap 14 can be set as desired. can do. For this reason, the lump of scrap 14 can be processed without the need for inversion, recompression, or cutting. Moreover, since it is not necessary to take measures to intentionally reduce the lump of scrap 14, a large amount of scrap 14 can be processed efficiently.

  It should be noted that the present invention can be implemented in variously modified, modified, or modified forms based on the knowledge of those skilled in the art without departing from the spirit of the present invention.
