  However, the above-described conventional briquette manufacturing method using a press has a problem in that the briquette cannot be continuously formed, so that it cannot be efficiently manufactured.

  The present invention has been made to address such problems, and an object of the present invention is to provide a briquette forming apparatus capable of continuously forming a large number of briquettes.

  In order to achieve the above-described object, a structural feature of the briquette molding apparatus according to the present invention is a briquette molding apparatus for molding a granular metal material into a briquette, which includes a molding recess and a molding recess. A molding die having a material filling port formed in the upper part of the mold and a briquette outlet formed in the lower part of the molding recess, a filling opening / closing means for opening and closing the material filling port, and a takeout for opening and closing the briquette outlet Opening and closing means, a pressing portion that can move in and out in a substantially horizontal direction with respect to the molding recess and moves to the inside of the molding recess to press and mold the metal material filled in the molding recess, and filling and opening The metal material filled in the molding recess through the material filling port is formed into a briquette by molding the molding material through the material filling port by operating the means, the take-off opening / closing means, and the pressing part in conjunction with each other. Yellowtail In that it comprises from Tsu ingestion outlet drive to retrieve the briquettes.

  In the briquette molding apparatus configured as described above, a material filling port for taking in the metal material from above is provided in the molding recess for molding the briquette in the molding die, and the briquette removing for taking out the briquette downward from the molding recess. There is an exit. And the filling opening-closing means which opens and closes a material filling port is installed. For this reason, by operating the filling opening / closing means, the material filling port can be opened to fill the molding recess with the metal material, or the material filling port can be closed. Also, an extraction opening / closing means for opening and closing the briquette outlet is provided.

  Furthermore, the pressing part which shape | molds the metal material with which it filled in the recessed part for shaping | molding by moving to the inner side of the recessed part for shaping | molding is installed so that advancing / retreating is possible with respect to the recessed part for shaping | molding. Then, by the operation of the driving device, the filling opening / closing means, the extraction opening / closing means, and the pressing portion are operated in conjunction with each other. For this reason, a metal material is sequentially filled into the molding recess from the material filling port, thereby forming the metal material filled in the molding recess with the pressing portion, and taking out the molded briquette from the briquette outlet. The operation can be performed continuously. As a result, a large amount of briquettes can be efficiently formed. The driving device in this case may be constituted by a plurality of driving devices that respectively operate the filling opening / closing means, the take-out opening / closing means and the pressing portion, or the filling opening / closing means, the taking-out opening / closing means and the pressing portion can be moved. You may comprise with one drive device.

  Another structural feature of the briquette molding apparatus according to the present invention is that the filling opening / closing means is composed of an upper lid that opens and closes the material filling port by moving along the upper surface of the molding die, and the extraction opening / closing means is formed by molding. It exists in having comprised with the lower cover which opens and closes a briquette taking-out port by moving along the lower surface of a metal mold | die.

  In this briquette molding apparatus, an upper lid for opening and closing the material filling port is installed on the upper surface of the molding die, and a lower lid for opening and closing the briquette outlet is installed on the lower surface of the molding die. For this reason, by moving the upper lid on the upper surface of the molding die, the material filling port can be opened to fill the molding recess with the metal material, or the material filling port can be closed. In addition, by moving the lower lid on the lower surface of the molding die, the molded briquette can be taken out from the briquette outlet, and the briquette outlet is closed to prevent the metal material in the molding recess from falling outside. You can do it.

  Still another structural feature of the briquette molding apparatus according to the present invention is that the molding die can be moved back and forth in a substantially horizontal direction with respect to one die so that the opposite surfaces of each other can be moved back and forth. Consists of a pair of molds with molding recesses and a gap between the molds formed by moving the briquette outlet in the direction in which the other mold is separated from one mold. The filling opening / closing means is constituted by an upper lid that opens and closes the material filling port by moving along the upper surface of the molding die, and the take-off opening / closing means is constituted by the pair of molds capable of moving forward and backward. .

  In the briquette forming apparatus configured as described above, a material filling port for taking in the metal material is provided at the upper part of the concave portion for forming the briquette in the molding die, and a briquette outlet for taking out the formed briquette downward Is formed by a gap between the molds formed by moving the other mold away from the one mold. And the upper cover which opens and closes a material filling port is installed in the upper surface of a shaping die. For this reason, by moving the upper lid on the upper surface of the molding die, the material filling port can be opened to fill the molding recess with the metal material, or the material filling port can be closed. Further, the briquette outlet can be opened and closed by opening and closing the molds by moving the other mold in the opposite direction of the mold with respect to the one mold.

  Yet another structural feature of the briquette molding apparatus according to the present invention is that it comprises a material reservoir that penetrates up and down, and reciprocates in a substantially horizontal direction above the molding die by driving of the driving device. The material conveying part which receives the metal material supplied from the material accommodating part at the position by the material reservoir and connects the material reservoir to the material filling port at the other position and fills the molding material with the metal material in the material reservoir. It is in having established. According to this, for example, if the material storage unit is installed above the material conveyance unit and the metal material falling from the material storage unit is sequentially received by the material reservoir, the material conveyance unit is simply reciprocated, The molding material can be intermittently filled with the metal material at regular time intervals. When the material reservoir and the material filling port are not in communication, the lower end opening of the material reservoir is closed by a predetermined portion.

  Still another structural feature of the briquette molding apparatus according to the present invention is that the drive device is driven to advance and retract from the surface facing the pressing portion on the peripheral surface forming the molding recess of the molding die with respect to the molding recess. When the pressing part is retracted from the molding recess and the briquette outlet opens, the extrusion part moves the briquette molded in the molding recess to the briquette outlet. is there. According to this, when taking out the briquette formed by the pressing of the pressing portion, when the pressing portion retreats from the concave portion for molding, the lower lid and the extrusion portion, or the other of the pair of molds and the extrusion portion are brought together. The briquette outlet is moved, and the formed briquette is pushed out to the briquette outlet side by the pushing portion. For this reason, even if a lot of briquettes are continuously formed, the briquettes can be taken out reliably and smoothly.

  Still another structural feature of the briquette forming apparatus according to the present invention is that the drive device reciprocates along the substantially horizontal direction of the displacement portion corresponding to the plurality of drive portions with respect to the rotational movement of the shaft provided with the plurality of drive portions. This is because it is composed of a shaft mechanism that changes into motion and a motor that rotates the shaft.

  As a mechanism for changing the rotational movement of the shaft into a reciprocating movement along a substantially horizontal direction, a crank mechanism for changing the rotating movement of the crankshaft into a reciprocating movement along a substantially horizontal direction of a plurality of displacement portions is possible. In this case, for example, different portions of the crankshaft are used as drive units, and one ends of a plurality of connecting rods and the like are rotatably connected to the plurality of drive units. Then, the other end of the connecting rod or the like is used as a displacement portion, and a member that reciprocates such as an upper lid, a lower lid, or a pressing portion can be connected to each displacement portion. According to this, the upper lid, the lower lid, the pressing portion and the like can be reciprocated while changing the timing and the movement width.

  As a result, when the material filling port is opened and the metal material is filled in the molding recess, the briquette outlet is closed, the pressing portion is retracted from the molding recess, and the pressing portion is moved to the inside of the molding recess. When the metal material is molded, the material filling port is closed with the upper lid and the briquette outlet is closed. When the briquette outlet is opened and the briquette is taken out, the pressing portion can be retracted from the molding recess. In addition, according to the present invention, since the drive device is only one device, the structure of the briquette forming device is simplified. In addition, although the upper lid, the lower lid, the pressing portion, and the like are cited as examples of those operated by the driving device, the other devices constituting the filling opening / closing means and the extraction opening / closing means are similarly operated by the driving device. . Further, as a mechanism for changing the rotational movement of the shaft into a reciprocating motion along a substantially horizontal direction, a cam mechanism configured by attaching a plurality of different cams to the shaft can be used.

  Still another structural feature of the briquetting molding apparatus according to the present invention is that the briquette forming portion of the molding recess is formed such that the cross section expands in the direction opposite to the pressing direction of the pressing portion. There is. According to this, since the shape of the briquette to be molded becomes a flared shape such as a cone, a triangular pyramid, a quadrangular pyramid or the like in the extrusion direction, it is easy to take out the briquette from the concave portion for molding. In this case, the briquette outlet is formed in a shape through which the formed briquette can pass. Further, the portion other than the portion where the briquette is finally formed in the concave portion for molding does not have to be formed so that the cross section is expanded in the direction opposite to the pressing direction of the pressing portion.

  Hereinafter, a briquette forming apparatus according to an embodiment of the present invention will be described with reference to the drawings. 1 and 2 show a briquette forming apparatus 10 according to the embodiment. The briquette molding apparatus 10 includes a base 11 that is longer to the left and right (left and right in FIG. 1) than the front and rear (left and right in FIG. 2), and both the front and rear sides of the left end portion and the front and rear sides of the center of the base 11. And a hill 12 including four pillars and the like provided respectively. In addition, an apparatus main body installation table 13 having a width smaller than that of the base 11 is installed on a portion of the base 11 excluding both end portions in the front-rear direction between the left end portion and the right end portion. A box-shaped housing portion 14 is installed in a portion excluding the right end side portion on 13.

  As shown in FIGS. 3 to 5, the molding unit 20 is installed in a portion located on the inner side of the hill 12 on the housing unit 14, and the right side portion on the housing unit 14 and the apparatus main body installation table 13. A driving device 30 for operating the molding unit 20 is provided across the right end side portion of the motor. In addition, a hopper 15 as a material accommodating portion of the present invention is installed on the upper part of the hill 12. In this hopper 15, the molding material (not shown) which consists of an aluminum granular material as a metal material of this invention is accommodated.

  The molding unit 20 includes a molding die 21, four plungers 22 as pressing portions according to the present invention, a movable support plate 23 for moving the four plungers 22 back and forth with respect to the molding die 21, and an extrusion unit according to the present invention. Four extruding pins 24, a lower lid 25, a material conveying unit 26, and the like are provided. The molding die 21 is installed on the left side of the upper surface of the housing portion 14, and as shown in FIGS. 6 and 7, four molding recesses 21 a extending left and right are spaced apart from each other at a predetermined interval. They are kept parallel to each other.

  The cross-sectional shape of the right side portion of each molding recess 21a is formed in a substantially square shape, but the longitudinal section of the left side portion where briquette B is finally formed in each molding recess 21a (the extending direction of the molding recess 21a ( The vertical cross-section) and the horizontal cross-section along the left-right direction) both have a shape in which the up and down direction of the trapezoid is the extending direction of the molding recess 21a and the top of the trapezoid is positioned on the left side and the bottom of the trapezoid is positioned on the right Is formed. In other words, the portion of the molding recess 21a that finally forms the briquette B is formed such that its cross section expands in the direction opposite to the pressing direction of the plunger 22 described in detail later. A material filling port 21b communicating with the outside is formed at the center in the left and right direction of the upper portion of the molding recess 21a in the molding die 21, and a substantially central portion in the left and right direction of the lower portion of the molding recess 21a in the molding die 21. Is formed with a briquette outlet (not shown) communicating with the outside.

  The plunger 22 is composed of a shaft body incorporated in the molding die 21, and the rear end portion is connected to the movable support plate 23. The distal end portion of the plunger 22 moves in the molding recess 21a as the movable support plate 23 reciprocates in the left-right direction, and the molding material is molded by the pressure accompanying the movement of the plunger 22, and the briquette B ( 8) is obtained. The briquette B can be a truncated quadrangular pyramid in a form in which the head is directed in the pressing direction of the plunger 22 and the head is cut. In FIG. 8, A indicates the pressing direction of the plunger 22. The extrusion pin 24 is provided so as to be able to advance and retreat into the molding recess 21a from the surface (the left side surface of the molding recess 21a) facing the plunger 22 on the peripheral surface forming the molding recess 21a. By moving to the inner side of 21a, the briquette B molded in the molding recess 21a is moved to the briquette outlet side.

  The push pin 24 is connected to a crankshaft 31 of a driving device 30 to be described later via a driving force transmission unit 27 and reciprocates left and right as the crankshaft 31 rotates. The driving force transmission unit 27 includes a main shaft 27a connected to the crankshaft 31 side, a sub shaft 27b connected to the push pin 24 side, and a lever portion that changes the reciprocating movement of the main shaft 27a to the sub shaft 27b. 27c. The lever portion 27c is rotatably supported at a substantially central portion in the longitudinal direction by a support shaft 27d. For this reason, when the main shaft 27a moves to the left, the push pin 24 moves to the right, and when the main shaft 27a moves to the right, the push pin 24 moves to the left.

  The lower lid 25 is movable in the left-right direction on the lower surface of the molding die 21, and moves to the left to close the briquette outlet, and moves to the right to open the briquette outlet. The lower lid 25 is connected to the auxiliary shaft 27b via a pair of connecting rods 25a, and moves to the left and right together with the push pin 24 by the operation of the driving force transmission unit 27. For this reason, when the push pin 24 moves to the right side and moves the briquette B to the briquette outlet side, the briquette outlet opens and the briquette B falls downward from the briquette outlet.

  The moving support plate 23 and the main shaft 27a are both connected to a predetermined portion on the crankshaft 31 side, but are different in connecting portions, so that they reciprocate left and right at different timings. In addition, a cam (not shown) is attached to the rear side portion of the crankshaft 31, and the rotation of the crankshaft 31 is changed to the left and right reciprocating movement of the main shaft 27a via the cam. A coil spring 27e as an urging means is provided between an end portion (left end portion) opposite to the cam of the main shaft 27a and a support member that supports the main shaft 27a, and the main shaft 27a is pushed by the cam. It is pushed back by the elastic biasing force of the coil spring 27e.

  The material transport unit 26 is composed of a plate body in which four material reservoirs 26a formed of holes penetrating vertically are formed at regular intervals in the front and rear, and is connected to the moving support plate 23, together with the plunger 22, Move left and right. Moreover, the material conveyance part 26 is supported by the frame-shaped guide part 28 so that a movement is possible, and when the material conveyance part 26 is located in the left end of the movement range, the guide part in which the lower end part of each material storage part 26a is located. A material passage hole 28 a is formed in the lower side portion of 28. In addition, when the material transport unit 26 is positioned at the right end of the movement range, the diameter of the upper side portion of the guide portion 28 where the upper end portion of each material reservoir 26a is located gradually increases from the lower side toward the upper side. The formed material receiving hole 28b is formed.

  And the chute | shoot 29 extended below is each installed in the lower part side of each material passage hole 28a, Below the lower end part of each chute | shoot 29, four materials which can communicate with the material filling port 21b of the molding die 21 are each provided. The receiving part 29a is installed. The material receiving portion 29 a is formed in a funnel shape and receives a molding material falling in the chute 29. Further, the lower end opening of the material receiving portion 29a is opened and closed by a plate-shaped upper lid 29b. The upper lid 29b is connected to the crankshaft 31 via a connecting member (not shown), and reciprocally moves left and right at a different timing from the moving support plate 23, so that the lower end opening of the material receiving portion 29a and the material The communication with the filling port 21b is made to be communicated or blocked.

  And the lower end part of the material supply pipe | tube 15a (only two are shown in FIG. 2) extended from the hopper 15 is located in the upper part of each material receiving hole 28b, respectively. When the material conveying unit 26 is positioned on the right side, the material conveying unit 26 receives the molding material falling from the hopper 15 through the material supply pipe 15a through the material receiving hole 28b and accommodates it in the material reservoir 26a. . Then, the material transport unit 26 moves to the left in that state, and when the material reservoir 26a is positioned at the upper end of the material passage hole 28a, the molding material in the material reservoir 26a passes through the material passage hole 28a. It falls into the chute 29.

  At this time, if the upper lid 29b does not close the material filling port 21b, the molding material passes through the material receiving portion 29a and the material filling port 21b and is filled into each molding recess 21a. If the upper lid 29b closes the material filling port 21b, the molding material is accumulated in the material receiving portion 29a. A briquette discharge pipe 16 that extends from the briquette outlet toward the front side of the apparatus main body installation base 13 is installed below the molding die 21, and below the lower end of the briquette discharge pipe 16. Is provided with a conveyor 17 for conveying the briquette B coming out of the briquette discharge pipe 16 to a predetermined collection place.

  The drive device 30 includes a crank portion that includes a crankshaft 31 and a motor portion that includes a motor 35 that rotates the crankshaft 31. The crank portion includes a support portion 32 that rotatably supports the crankshaft 31 and a pair of drive pulleys 33 provided at both ends of the crankshaft 31. The crankshaft 31 is provided with a plurality of cam portions 31a that are eccentric with respect to the central axis, and as shown in FIGS. 9 and 10, the crankshaft 31 is moved and supported via a crank rod 34, a crank rod pin 34a, and a moving block 34b. It is connected to the plate 23. Further, the crankshaft 31, the main shaft 27a, and the upper lid 29b are connected to different cam portions via connecting members (not shown). 9 and 10 are schematic views for explaining the crankshaft 31. In FIG. 10, there are some parts different from the other drawings, such as omitting two of the plungers 22.

  Each connecting member changes the rotation of the crankshaft 31 to a reciprocating movement in the horizontal direction and transmits it to the moving support plate 23, the main shaft 27a and the upper lid 29b, respectively. When the crankshaft 31 makes one rotation around the axis, the movable support plate 23 reciprocates left and right to return to the original position. As the movable support plate 23 moves, the plunger 22 and the material conveying unit 26 also move left and right. Move back and forth. Further, the push pin 24 and the lower lid 25 reciprocate left and right with a slight shift in timing from the movement of the plunger 22 and the material transport unit 26 by the action of the driving force transmission unit 27 and the like. The upper lid 29b also reciprocates left and right with a slight shift in timing from the plunger 22, the push pin 24, and the like.

  The motor unit includes a motor 35 and a transmission pulley 36 that transmits the driving force of the motor 35 to the drive pulley 33. The motor 35 is installed on an upper portion of a support base 37 provided on the right end side of the apparatus main body installation base 13 with the rotary shaft 35a protruding rearward. The rotating shaft 35a is connected to the transmission pulley 36 via a belt 35b. A support shaft 36a is fixed at the center of the transmission pulley 36, and both ends of the support shaft 36a are rotatably supported by a pair of bearings 38 provided on both sides of the support table 37 on the apparatus main body installation table 13. Has been.

  The transmission pulley 36 is attached to the rear end side of the support shaft 36a (the rear portion of the support base 37), and a small-diameter transmission pulley 36b is attached to the front end portion of the support shaft 36a. A belt 33 a is stretched between the transmission pulley 36 b and the drive pulley 33 located at the front of the pair of drive pulleys 33. The briquette molding apparatus 10 includes a control device (not shown) configured by a CPU, a ROM, a RAM, various circuits, and the like, and each device constituting the briquette molding apparatus 10 is controlled by the control device. Its operation is controlled.

  Next, the case where the briquette B is molded using the briquette molding apparatus 10 configured as described above will be described. The molding material used in this case is, for example, granulated by a regeneration process including a heating step and a granulation step. First, the aluminum can is heated by a rotary kiln or the like, and is then stirred on the surface. While burning and removing impurities such as applied paint, the can body and the lid are separated. Then, the aluminum material from which impurities have been removed is formed into a granular shape by pulverizing it with a granulator equipped with a hammer or the like.

  In this manner, the molding material obtained from the used aluminum can is first put into the hopper 15. Next, various settings are performed by operating the operation units included in the control device with the power supply of the control device turned on, and the briquette forming apparatus 10 is operated. As a result, the motor 35 is actuated to rotate the rotating shaft 35a. The rotation of the rotation shaft 35a is transmitted to the crankshaft 31 via the belt 35b, the transmission pulley 36, the support shaft 36a, the transmission pulley 36b, the belt 33a, and the drive pulley 33, and the crankshaft 31 rotates.

  The rotation of the crankshaft 31 causes the movable support plate 23 and the main shaft 27a to reciprocate left and right. Therefore, the plunger 22, the material transport unit 26, the push pin 24, and the lower lid 25 also move left and right at a predetermined timing and width. Move back and forth. At the same time, the upper lid 29b also reciprocates left and right. In this case, when the moving support plate 23 is retracted and the material reservoir 26a of the material transport unit 26 is positioned directly below the material receiving hole 28b of the guide unit 28, the material drops from the hopper 15 through the material supply pipe 15a. The incoming molding material is filled into the material reservoir 26a. Next, when the movable support plate 23 moves forward and the material reservoir 26a of the material transport unit 26 is positioned immediately above the material passage hole 28a of the guide portion 28, the molding material in the material reservoir 26a is transferred to the material passage hole. The material passes through the inside of the chute 29 and falls into the material receiving portion 29a.

  At this time, the lower end opening of the material receiving portion 29a is closed by the upper lid 29b, and the molding material accumulates in the material receiving portion 29a. Next, when the movable support plate 23 is retracted again, the molding material falling in the material supply pipe 15a is filled in the material reservoir 26a. The plunger 22 also moves backward together with the moving support plate 23. Then, when the upper lid 29b moves to the right side to connect the material receiving portion 29a and the material filling port 21b, the molding material in the material receiving portion 29a is filled into the molding concave portion 21a. Next, when the upper lid 29b moves to the left and closes the material filling port 21b, the moving support plate 23 moves forward, and the plunger 22 presses the molding material in the molding recess 21a to mold it. At this time, the molding material in the material reservoir 26a falls into the material receiver 29a.

  During this time, the push pin 24 and the lower lid 25 are maintained in a state of being retracted to the left side, but when the briquette B is formed and the plunger 22 is retracted, the push pin 24 and the lower lid 25 are advanced toward the right side. . As a result, the briquette outlet is opened and the briquette B is moved to the right side by the pressing of the push pin 24 and discharged from the briquette outlet to the briquette discharge pipe 16. And briquette B is conveyed by the conveyor 17 to a collection place. Next, the push pin 24 and the lower lid 25 are retracted to the left, and the upper lid 29b is moved to the right. As a result, the molding material in the material receiving portion 29a is filled into the molding recess 21a. Such an operation of the briquette forming apparatus 10 is repeatedly performed, and the briquette B is sequentially formed during the operation.

  As described above, in this briquette molding apparatus 10, the plunger 22, the push pin 24, the lower lid 25, the material transport unit 26, and the upper lid 29 b are moved in conjunction with each other by the operation of the driving device 30. For this reason, the molding material conveyed by the material conveying unit 26 is filled into the molding recess 21a from the material filling port 21b via the material receiving unit 29a, and the molding material is molded by pressing the plunger 22, and molding is performed. A series of operations for taking out the used briquette B from the briquette outlet is continuously performed. Thereby, a large amount of briquette B can be efficiently formed.

  Moreover, since the drive device 30 in the present invention is composed of a single device including a crank portion and a motor portion, the structure of the briquette forming device 10 is simplified and inexpensive. Furthermore, since the briquette forming apparatus 10 according to the present invention includes the extrusion pin 24, the briquette B can be taken out reliably and smoothly even if a large amount of the briquette B is continuously formed. In addition, the left side portion of the molding recess 21a, that is, the portion that finally forms the briquette B is formed so that the cross section expands in the direction opposite to the pressing direction of the plunger 22, so that the molding recess of the briquette B is formed. The removal from 21a becomes easy.

  In the embodiment described above, the metal material for forming the briquette B is aluminum. However, the metal material is not limited to aluminum, and any material can be used as a briquette such as steel. Even a granular material made of a metallic material can be used. In addition, in the briquette molding apparatus 10 described above, four concave portions 21a, chutes 29, etc. are provided, but the number of these can be increased to a greater number or less than three. You can also. Further, in the above-described embodiment, all the reciprocating members such as the plunger 22 are moved by one drive device 30, but each plunger 22 and the like may be moved by operation of different drive devices. However, only a specific object, for example, the upper lid 29 b may be moved by a driving device other than the driving device 30.

  In the above-described embodiment, the material filling port 21b is formed on the upper portion of the molding recess 21a, and the material filling port 21b is opened and closed by moving the upper lid 29b along the upper surface of the molding die 21. A filling opening / closing means for opening and closing the material filling port 21b is configured. Further, a briquette outlet is formed in the lower part of the molding recess 21a, and the briquette outlet is opened and closed by moving the lower lid 25 along the lower surface of the molding die 21 to open and close the briquette outlet. Opening and closing means are configured. Now, the filling opening / closing means and the extraction opening / closing means according to the present invention are not limited to those described above. For example, as the opening / closing means, a briquette forming apparatus according to another embodiment described below can be used.

  That is, as shown in FIG. 11, in the briquette molding apparatus 40 of this embodiment, the molding dies 41 forming the molding recesses 41a are opposed to each other in the substantially horizontal direction and are positioned on the left and right, while the other is advanced and retracted It consists of two molds. The left and right indicate the left and right in FIG. The left fixed die 41b, which is one mold, corresponds to the portion where the briquette B in the molding recess 41a is finally formed. The right moving mold 41c, which is the other mold, corresponds to the remaining portion in the molding recess 41a. A material filling port 41d is formed in the movable die 41c. The plunger 42 advances and retreats into the molding recess 41a from the right side of the movable die 41c, and the push pin 44 advances and retracts from the left side of the fixed die 41b into the molding recess 41a.

  In the above-described embodiment, the lower lid 25 is connected to the auxiliary shaft 27b via a pair of connecting rods 25a. However, in this embodiment, there is no lower lid, and the movable die 41c is used as an extraction opening / closing means. As shown in FIG. 12, it is connected to the auxiliary shaft 47b via a pair of connecting rods 47a. When the movable die 41c moves, the space between the dies is opened and closed as a briquette outlet 43 (FIG. 11 (c)). In an open state between the molds (a state where the opposite end surfaces of the molds are separated), a briquette outlet 43 is formed and opened. In a closed state between the molds (a state where the opposite end surfaces of the molds are in contact), the briquette removal is performed. The outlet 43 is closed and closed. By the operation of the driving force transmission unit 47, the movable die 41c moves to the left and right together with the push pin 44. When the push pin 44 moves to the right side and the movable die 41c moves to the right side, the briquette outlet 43 is formed and opened, and the briquette B falls from the briquette outlet 43.

  As shown in FIG. 12, the main shaft 47a of the driving force transmitting portion 47 is disposed so as to be pressed by the cam 52 attached to the crankshaft 51, and is transmitted through the cam mechanism. The rotation of 51 causes the main shaft 47a to reciprocate left and right. A coil spring 47e as an urging means is provided between the main shaft 47a and the end (left end) opposite to the cam 52, and a supporting member that supports the main shaft 47a. And is pushed back by the elastic biasing force of the coil spring 47e.

  In the present embodiment, the briquette outlet 43 is opened by the movement of the movable mold 41c, and is different from the one in which the briquette outlet is opened by the movement of the lower lid 25 as in the above-described one embodiment. Further, the plunger 42 is advanced from the state of FIG. 11A to the state of FIG. 11B to press the metal material to form the briquette B. As shown in FIG. 11C, when the briquette B is formed and the plunger 42 moves backward, the push pin 44 moves forward toward the right side, and the movable die 41c also moves toward the right side. When the space between the movable die 41c and the fixed die 41b is opened, a briquette outlet 43 is formed, and the briquette B is moved to the right side by pressing of the push pin 44, and the briquette outlet pipe (not shown) ).

  By the operation of the driving device, the plunger 42, the push pin 44, the moving mold 41c, the material conveying unit (not shown), and the upper lid 49b are moved in conjunction with each other. In this embodiment, the movable mold 41c is moved. However, the right mold can be a fixed mold and the left mold can be a movable mold, and both molds can be moved. It is also possible to do. It is sufficient if one mold moves relative to the other mold and a briquette outlet is formed between the molds. The structure of the other part of the briquette molding apparatus 40 according to this embodiment is the same as that of the briquette molding apparatus 10 described above. Accordingly, the same parts are denoted by the same reference numerals and the description thereof is omitted. The operational effects of the briquette molding apparatus 40 according to this embodiment are the same as those of the briquette molding apparatus 10 described above.
