Used for. A plurality of wheels 152 (see FIGS. 8 and 11) of the detachable carriage 151 are guided by the main body side rail 81 and the guide rail 96 which are continuous with each other, whereby the detachable carriage 151 is arranged at a use position. The operator extends from a first position that can be inserted into the molding machine main body 2 from above 85 to receive the turntable unit 41 from below and a second position that is disposed on the carriage guide 85 that is disposed at the use position. It is moved by pushing and pulling.

  As shown in FIG. 13, the detachable carriage 151 has a U-shape in plan view. The detachable carriage 151 is used with its U-shaped open end directed toward the molding machine main body 2, and is therefore used with the U-shaped direction reversed from the carriage guide 85 disposed at the use position. .

  The left and right side portions of the detachable carriage 151 that are parallel to each other form a receiving portion 153 that receives the turntable unit 41 from the lower side, and the front side portion that integrally connects the pair of side portions also connects the turntable unit 41 from the lower side. A receiving portion 154 is formed. These receiving portions 153 and 154 have a receiving member on the upper surface and a pin receiving hole 155. The upper end of the pin receiving hole 155 is opened on the upper surface of the receiving member. These three pin receiving holes 155 are provided every 90 degrees in accordance with the arrangement of the through holes 49 a of the supported portion 49.

  As representatively shown in FIG. 11, one end of the axle 152 a of each wheel 152 protrudes longer than the other end. One end of the longer side is opposed to the second stopper end 111b of the side stopper 111 arranged at the raising position from the lower side in a state where the detachable carriage 151 is arranged on the carriage guide 85. . As a result, even if the detachable carriage 151 may be lifted, the axle 152a is immediately hooked on the second stopper end 111b, preventing further movement upward. At the same time, even if the wheel 152 is detached from the guide rail 96 and moved in the left-right direction of the carriage guide 85, the axle 152a immediately hits the stopper main part of the side stopper 111 and is prevented from moving further in the left-right direction. .

  The transport carriage 161 of the support equipment 71 is a handcart having a handle 162 formed by bending a metal pipe as shown in FIGS. 2 and 14, and on the base 163 as shown in FIGS. 2 and 15. The turntable receiving part 164 is fixed. The turntable receiving portion 164 has a tower shape, and a screw receiving portion 165 having a screw hole 165a is formed at the upper center thereof. A screw hole is opened in the upper end surface of the screw receiving portion 165. As shown in FIG. 15, the base portion 163 is provided with a pair of jig receiving portions 166 having U-shaped grooves that open upward.

  The height of the turntable receiver 164 is higher than the height of the transport carriage 161. As shown in FIG. 14, the transport carriage 161 is detachably mounted on the base portion 163. The transport carriage 161 can be taken in and out through the inside of the handle 162.

  Reference numeral 167 in FIG. 15 indicates a fastening jig. The fastening jig 167 includes a screw shaft 167a and a pressing head 167b. The fastening jig 167 is removably supported by the transport carriage 161 by fitting both ends of the screw shaft 167a into the U-shaped groove of the jig receiving part 166 so as to be detachable from above. The screw shaft 167a has a length that penetrates the central portion of the rotary disk unit 41 in the vertical direction, and can be detachably screwed into the screw receiving portion 165. The diameter of the presser head 167 b is larger than the diameter of the pressure receiving hole 61 of the positioning member 45 provided in the rotary disk unit 41.

  The normal state of the tablet press 1 is shown in FIG. In this state, the turntable unit 41 is placed on the lower main shaft 12, and the key groove-like driving force transmitting portion 13 a of the driving force transmitting body 13 and the key-shaped power receiving portion 46 a of the power receiving body 46 are fitted together. Is engaged. Along with this, the lifting shaft 73 of the rotating disk lifting mechanism 72 is disposed at the first raised position. In the state where the lifting shaft 73 is disposed at the first raised position, the upper end portion 73 a is fitted in the positioning hole 65 without contacting the stepped portion 66 of the power receiving body 46, so The turntable unit 41 is positioned in a centered state.

  Further, in the normal state of the tableting machine 1, the upper spindle 22 is fitted into the pressure receiving hole 61 of the rotary disk unit 41 from above by the rotary disk support device 21 and urged downward with a predetermined force. Yes. Thereby, the turntable unit 41 is positioned so as to be centered with respect to the upper main shaft 22, and is sandwiched between the lower main shaft 12 and the upper main shaft 22.

  The downward urging of the turntable unit 41 is performed as follows. First, as the ball screw shaft 24a of the ball screw 24 is rotated by driving the upper spindle lifting mechanism 25 and the nut 24b, the spindle holder 23, and the upper spindle 22 are lowered integrally, the truncated cone portion of the upper spindle 22 is moved. Since it protrudes into the molding chamber 2a, this truncated cone part fits into the positioning 65 of the positioning member 45 from above to center the rotating disk unit 41. After this time, the upper main shaft 22 cannot be lowered, but since the rotation of the ball screw shaft 24a continues, the ball screw shaft 24a is raised while rotating. As a result, the disc spring 26 is compressed via the disc spring retainer 30, so that an urging force is applied to the turntable unit 41 downward. When this urging force reaches a predetermined value, the detected member 31 pushed up by the ball screw shaft 24a together with the disc spring cage 30 is detected by the ascending sensor 32, and the upper spindle is detected based on the detection signal. The driving of the lifting mechanism 25 is stopped. Thereby, the state which urged | biased the turntable unit 41 downward with the predetermined spring force is hold | maintained.

  In this state, when the lower main shaft 12 is rotationally driven by the rotating disk driving device 15, the rotating disk 42 is rotated together with the lower main shaft 12 via the driving force transmitting portion 13a and the power receiving portion 46a. A tablet molding operation is performed accordingly. In this case, the positioning member 45 and the upper cam holder 43 of the turntable unit 41 and the upper cam 44 fixed to the positioning member 45 do not rotate, and the bearing holder 47, the lower rod track support 48, and various lower rod guide tracks 54. Does not rotate.

  Next, a procedure for executing the take-out mode and taking out the turntable unit 41 from the molding machine main body 2 for cleaning and outer setup of the turntable 42 and the like will be described.

  First, as a preparation for this, the equipment installed around the unit that obstructs the lateral movement of the turntable unit 41 to the front side of the molding machine body 2 is removed with the molding chamber 2a opened. Examples of the symmetric device in this case include a powder feeder, a scraper, a flow port arranged continuously with the scraper, a dust collection nozzle, a shelf board, a weight adjusting track, and the like.

  Subsequently, the rotating disk drive device 15 is driven at a low speed to rotate the rotating disk unit 41 to a position where it can be pulled out in the horizontal direction. Here, the position where the turntable can be pulled out refers to the direction (longitudinal direction) in which the driving force transmitting portion 13a and the power receiving portion 46a that are fitted to each other extend (longitudinal direction). Points to a parallel position. It should be noted that disposing the turntable unit 41 in the drawable position in this way can be substituted if the turntable unit 41 is placed in the drawable position after removing the device.

  Further, when removing the device, if at least the lower rod 52 is not removed among the upper rod 51 and the lower rod 52, the lower rod 52 is prevented from falling off. This operation is performed by attaching a lower collar receiving member 69 (see FIGS. 1 and 2) on the rear side as viewed from the front of the rotating disk 42 arranged at the pullable position. Accordingly, it is possible to prevent the lower eyelid 52 positioned right above the lower eyelid pressure roller 57 at the drawable position from falling off the turntable 42 with the drawing work of the turntable unit 41 described below. Note that the lower rod 52 disposed at a position other than directly above the lower rod pressure roller 57 is prevented from dropping by various lower rod guide tracks 54 on the lower rod track support 48 and the like. Further, the above-described lower lid drop-off prevention work can be omitted when the lower lid 52 that may fall off at least as the rotary plate unit 41 is pulled out of the lower plate 52 is removed from the rotary plate 42.

  After the above preparation is completed, the drive room cover 115 is removed, and the carriage guide 85 is caused to pivot upward from the retracted position shown in FIG. 6 about the pivot 88 to the use position shown in FIG. Deploy.

  In this case, the pair of left and right brackets 101 are rotated about the hinge 102 and moved from the storage position indicated by the two-dot chain line in FIG. 8 to the use position indicated by the solid line, and the base end portions 101a of the brackets 101 are moved. As shown in FIG. 9, the metal fitting 90 is fitted. As a result, the bracket 101 is held in a state of being disposed at a right angle to the lower side with respect to the guide plate 95, and the front end surface 101b of the bracket 101 disposed at the use position is engaged with the rear surface of the bracket stopper 104. .

  As shown in FIGS. 1 to 3, the carriage guide 85 arranged in the use position protrudes forward of the molding machine main body 2 while maintaining the level, and the guide rail 96 fixed on the guide plate 95 is As shown in FIG. 7, it continues straight to the front end of the main body side rail 81 fixed to the lower frame 3.

  Further, the pair of left and right side stoppers 111 of the carriage guide 85 arranged at the use position are rotated so as to be raised around the hinges 112, respectively, and are shown by solid lines from the lying position shown by the two-dot chain line in FIG. Place it in the raising position. Thereby, the side stopper 111 is held at the raised position by the magnetic force of the magnet 113.

  Next, the rotating disk support device 21 is driven to raise the upper main shaft 22. In this case, since the ball screw shaft 24a is rotated in the opposite direction to the case where the turntable unit 41 is pushed down, the nut 24b, the spindle holder 23, and the upper spindle 22 are all raised. As a result, when the upper main shaft 22 is lifted up to the height position where the upper main shaft 22 passes through the pressure receiving hole 61 and enters the upper frame 4, this is detected by a sensor (not shown). Therefore, the driving of the turntable support device 21 is stopped based on the detection signal of this sensor, and the upper main shaft 22 is held at the upper limit position.

  Thereafter, the rotating disk lifting mechanism 72 is driven and the lifting shaft 73 is raised, so that the upper end portion 73a hits the step 66 of the power receiving body 46 from below and pushes up the rotating disk unit 41. This push-up is possible because the upper spindle 22 is retracted upward as described above, and there is a gap between the upper end surface of the turntable unit 41 and the upper frame 4 as shown in FIG. is there. In this case, the push-up dimension of the turntable unit 41 only needs to be several mm or less, and it is not necessary to push up the drive force transmission portion 13a and the power receiving portion 46a so as to be disengaged. When the turntable unit 41 is pushed up, when the detachable carriage 151 is inserted into the space below the supported portion 49 of the turntable 42, the detachable carriage 151 rotates to a height position that does not interfere with the supported portion 49. A panel unit 41 is arranged.

  In this state, the rubber stopper that has blocked the through hole 49a of the supported portion 49 is removed, and the front stopper 106 of the carriage guide 85 is moved from the stopper position to the retracted position. The front stopper 106 is moved to the retracted position by removing the insertion / removal pin 109 and rotating the front stopper 106 180 degrees about the pivot 107 in a direction away from each other.

  After such a carriage insertion preparation, the prepared detachable carriage 151 is manually placed on the carriage guide 85 from the front end side, and then the guide carriage 96 and the main body side rail 81 are guided to the detachable carriage 151. It is manually inserted into the molding chamber 2a from above the carriage guide 85. During this insertion, the wheel 152 of the detachable carriage 151 does not interfere with the side stopper 111 disposed at the raised position, and passes below the second stopper end portion 111b to guide the guide rail 96. To the main body side rail 81.

  With the above movement of the detachable carriage 151, the receiving portions 153 and 154 are inserted into the space below the supported portion 49 of the rotating disk 42. In a state where this insertion reaches a predetermined position, that is, a first position where the supported portion 49 can be received from below, the detachable carriage 151 is held at that position. This holding is performed, for example, by inserting a fixing pin (not shown) that is passed through the lower end of the detachable carriage 151 from above into a fixing hole (not shown) provided in the lower frame 3. Since the detachable carriage 151 is held in the first position, the mutual positional relationship between the detachable carriage 151 and the turntable unit 41 arranged at the drawable position as described above is determined. A pin receiving hole 155 faces directly below the through hole 49a.

  Thereafter, positioning pins (not shown) are inserted into the through holes 49a located on the front side and the left and right sides of the rotating plate 42 and the pin receiving holes 155 facing the lower side of the rotating plate 42 from above, and the rotating plate is moved up and down. The mechanism 72 is driven and the elevating shaft 73 is lowered. Then, when the elevating shaft 73 is lowered to the lower limit position where the upper end portion 73a of the elevating shaft 73 is removed below the positioning hole 65 of the power receiver 46, it is detected by a sensor (not shown). Based on the above, the driving of the rotary disk lifting mechanism 72 is stopped, and the lifting shaft 73 is held at the lower limit position.

  As the elevating shaft 73 is lowered, the turntable unit 41 is lowered at an early stage, so that the turntable unit 41 is delivered to the detachable carriage 151 from above. At this time, the lower portion of the positioning pin (not shown) penetrating the through hole 49a is inserted deeper into the pin receiving hole 155 of the detachable carriage 151. The positioning pin may be inserted after the turntable unit 41 is placed on the detachable carriage 151. When the turntable unit 41 is placed on the detachable carriage 151 as described above, the seating plate 67 of the turntable unit 41 and the driving force transmitting body 13 are slightly separated due to the thickness of the detachable carriage 151 in the vertical direction. Yes. Further, since the elevating shaft 73 is lowered to the lower limit position, the restriction of the rotating disk unit 41 by the elevating shaft 73 is released, so that the rotating disk unit 41 moves forward of the molding machine body 2 with respect to the lower main shaft 12. It is ready to be pulled out.

  Next, after removing the fixing pin, the detachable carriage 151 on which the turntable unit 41 is placed is guided by the main body side rail 81 and the guide rail 96 continuous to the front side, and is molded manually. Pull out from the machine body 2 onto the carriage guide 85. In this way, the detachable carriage 151 pulled out to a predetermined position on the carriage guide 85, that is, the second position, has a fixing pin (not shown) provided on the guide plate 95 with the fixing pin passed through the lower end thereof from above. By being inserted into the hole, it is held by the carriage guide 85.

  The turntable unit 41 is taken out from the molding machine main body 2 by the above take-out mode. That is, as described above, in this take-out mode, the carriage guide 85 having the guide rail 96 is placed on the turntable unit 41 so that the guide rail 96 is continuous with the main body side rail 81 installed in the molding machine main body 2. A step of disposing the molding machine main body 2 on one side located on the take-out side, a step of raising the rotating disk unit 41 with respect to the driving force transmitting portion 13a, and a supported portion 49 of the rotating disk 42 on the lower side. After the detachable carriage 151 having the receiving portions 153 and 154 supported from above is arranged on the carriage guide 85, it is guided by both rails 81 and 96 and inserted into the molding machine main body 2, and the raised rotating disk unit 41 The step of disposing the supported portion 49 at the first position where it can be received from the lower side, the step of lowering the turntable unit 41 and placing the turntable unit 41 on the attachable carriage 151, and the attachable carriage 151 The guides 81 and 96, move laterally, and withdraw from the molding machine main body 2 onto the second position of the carriage guide 85, and the rotary table unit 41 is formed by performing these processes. It is taken out from the main body 2.

  Therefore, in this take-out mode, the molding machine main body 2 can be used as a reference for the height positions of the driving force transmission body 13, the rotating disk unit 41, and the detachable carriage 151 of the molding machine main body 2. At the same time, the detachable carriage 151 can be positioned in the left-right direction orthogonal to the direction in which the rails 81, 96 extend by the main body side rail 81 and the guide rail 96 that are continuous in the front-rear direction. Thereby, even if the floor surface on which the molding machine main body 2 is installed is inclined, an appropriate mutual positional relationship among the driving force transmission body 13, the rotary disk unit 41, and the detachable carriage 151 is maintained. Therefore, the tip of the fork inserted into the molding machine main body 2 does not interfere with the rotary disk unit or the like unlike when the rotary disk unit 41 is taken out from the molding machine main body 2 using a forklift. The take-out operation of the provided turntable unit 41 can be performed smoothly.

  Next, the procedure for removing the turntable unit 41 from the cart guide 85 and transferring it to the transport cart 161 in the tableting machine 1 of this embodiment will be described.

  First, as shown in FIGS. 1 and 2, the prepared conveyance carriage 161 is arranged below the carriage guide 85 arranged at the use position and held on the front side of the molding machine main body 2. As shown in FIG. 1, the holding is performed by overlapping the connecting portion 161a provided on the transport carriage 161 on the upper surfaces of the pair of left and right positioning brackets 6 provided on the molding machine body 2, and then connecting the connecting pin 169 to the connecting portion 161a.

  Thereafter, the guide lifting mechanism 121 is driven so that the cart guide 85 is lowered. In this case, when the nut 122b is lowered by the rotation of the ball screw shaft 122a, the base 86 of the carriage guide 85 is lowered along the linear guide 87. Accordingly, as the carriage guide 85 is lowered to the lower limit position, the turntable unit 41 placed on the carriage guide 85 is moved to the turntable receiving portion of the transport carriage 161 as shown by a two-dot chain line in FIG. 164 is passed on. Thereby, the turntable unit 41 is separated above the detachable carriage 151. In this case, the positioning pin does not interfere.

  In this state, the turntable unit 41 placed on the turntable receiving portion 162 is held on the transport carriage 161. This holding is performed using a fastening jig 167 removed from the base 163. That is, the tightening jig 167 is inserted into the pressure receiving hole 61 of the turntable unit 41 with the screw shaft 167a at the head, and is inserted into the screw hole 62 and the positioning hole 65 sequentially provided below the rotation jig unit 167 and rotated. This is performed by screwing into the screw hole 165a of the screw receiving portion 165 of the board receiving portion 164 and tightening. By this tightening, the turntable unit 41 is held between the presser head 167 b of the fastening jig 167 and the turntable receiving portion 164, so that the turntable unit 41 is held by the transport carriage 161.

  Next, three positioning pins (not shown) passed through the through holes 49a are pulled out and removed, and the fixing pins holding the detachable carriage 151 in the second position are pulled out and detached. The cart 151 is manually removed from the cart guide 85. In this case, the detachable carriage 151 is moved away from the molding machine body 2 and is taken out through the inside of the handle 162 of the conveyance carriage 161.

  Thereafter, the connecting pin 169 is removed upward to release the connection between the molding machine main body 2 and the transport carriage 161, and the transport carriage 161 holding the turntable unit 41 is moved to the carriage guide 85 at the use position. Move from below to a suitable place. Thereby, the operation of removing the turntable unit 41 from the carriage guide 85 is completed.

  Subsequently, post-processing for storing the cart guide 85 is performed. In this post-processing, first, the front stopper 106 is held at a stopper position across the open end of the guide plate 95. This operation is performed by rotating the pair of front stoppers 106 so that their tip portions are aligned with each other, and inserting the insertion / removal pin 109 into the tip portions overlapping each other from above. Next, the guide raising / lowering mechanism 121 is driven to raise the carriage guide 85 to the upper limit position (use position). Thereafter, the cart guide 85 is folded. In other words, the bracket 101 is rotated and disposed at the retracted position indicated by the two-dot chain line in FIG. 8, and the side stopper 111 is rotated and disposed at the lying position indicated by the two-dot chain line in FIG. The guide 85 is folded. Then, the carriage guide 85 is rotated downward to be vertically arranged at the storage position, and the drive room cover 115 is attached to the molding machine body 2.

  Next, a procedure for mounting the taken out rotating disk unit 41 to the molding machine body 2 in the tableting machine 1 of the present embodiment will be described. This procedure is generally performed in the reverse procedure of the extraction procedure described above.

  That is, as preparation for the mounting mode, first, the rotating disk drive device 15 is driven at a low speed to rotate the rotating disk unit 41 to a position where the rotating disk unit 41 can be received from the lateral direction, and then the carriage at the use position from the conveyance carriage 161. A procedure for delivering the rotating disk unit 41 that has been cleaned on the guide 85 is performed. Here, the acceptable position is the same as the position where the turntable can be pulled out.

  First, after removing the drive room cover 115 from the molding machine main body 2, the cart guide 85 arranged at the storage position is assembled and arranged at the use position. This procedure is the same as the procedure already described when removing the turntable unit 41. In this case, the front stopper 106 is disposed at the stopper position, and the side stopper 111 is disposed at the raised position by the assembly. Subsequently, the guide raising / lowering mechanism 121 is driven to lower the cart guide 85 arranged at the use position to the lower limit position.

  Next, in this state, the front stopper 106 is moved to the retracted position, and then conveyed to the molding machine main body 2 and the carriage guide 85 through the turntable receiving portion 164 of the conveyance carriage 161 to the open end of the guide plate 95. The carriage 161 is set. As a result, the turntable receiving portion 164 on which the turntable unit 41 is placed is inserted and disposed between the pair of left and right rail installation portions 95a of the guide plate 95, and the lower side of the cart guide 85 at the lower limit position. The base portion 163 of the transport carriage 161 is inserted and arranged. Then, the transport carriage 161 is connected to the positioning bracket 6 of the molding machine body 2 using the connection pins 169. As a result, the turntable unit 41 held by the transport carriage 161 is positioned front-rear and left-right with respect to the carriage guide 85.

  Subsequently, the detachable carriage 151 is set on the carriage guide 85. In this case, the detachable carriage 151 is inserted between the guide plate 95 of the carriage guide 85 and the turntable unit 41 through the inside of the handle 162 of the transport carriage 161, and the detachable carriage 151 is inserted by inserting a fixing pin (not shown). It is held on the cart guide 85. Thereby, the detachable carriage 151 is held in front, rear, left and right with respect to the turntable unit 41 disposed above the detachable carriage 151. Further, in this state, positioning pins (not shown) are passed through the three through holes 49a of the turntable 42 from above and are also inserted into the pin receiving holes 155 of the detachable carriage 151 facing below these.

  Thereafter, the fastening jig 167 is rotated in the loosening direction and removed from the screw receiving portion 165, and then the fastening jig 167 is pulled out above the turntable unit 41, and the guide lifting mechanism 121 is driven to drive the cart guide 85. Is raised from the lower limit position to the upper limit position (use position). As a result, the turntable unit 41 placed on the turntable receiving portion 164 is passed over the receiving portions 153 and 154 of the detachable carriage 151 that rises together with the carriage guide 85, and the carriage guide 85 is used. As a result, the detachable carriage 151 on which the rotating disk unit 41 that has been cleaned is placed is placed at the second position.

  After the above mounting preparation work, the mounting mode is executed according to the following procedure, and the turntable unit 41 is mounted on the molding machine body 2.

  In this mounting mode, first, the connection between the detachable carriage 151 and the carriage guide 85 arranged at the second position is released by removing the fixing pin (not shown), and then the detachable carriage 151 is moved to the guide rail 96. And it guide | induces with the main body side rail 81 continuous to this, and it inserts by hand in the 1st position in the molding chamber 2a from on the trolley | bogie guide 85. FIG. After this insertion, the detachable carriage 151 is held at the first position using the fixing pin.

  Thus, as the detachable carriage 151 is moved laterally and inserted into the first position, the power receiving portion 46a having a key shape of the rotary disk unit 41 placed on the detachable carriage 151 is provided on the lower spindle 12. The driving force transmission body 13 on the side has a key groove-like driving force transmission portion 13a.

  Next, the turntable lifting mechanism 72 is driven to raise the lifting shaft 73 to the upper limit position. Along with this, the upper end 73 a of the lifting shaft 73 is inserted into the positioning hole 65 of the rotating plate 42 and hits the stepped portion 66, so that the rotating plate unit 41 is pushed up and above the detachable carriage 151. Are kept in a separated state.

  In this state, preparations for pulling out the detachable carriage 151 to the second position are made. In this preparatory work, first, the connection between the molding machine main body 2 and the transport carriage 161 is released, and the transport carriage 161 is moved to a position deviated from the lower side of the carriage guide 85 arranged at the use position. Thereafter, the three positioning pins (not shown) inserted into the supported portion 49 of the rotating disk 42 are pulled upward, and further the fixing pins (not shown) are pulled out to form the molding machine main body 2 and the detachable carriage 151. Disconnect from the link.

  After this preparatory work, the detachable carriage 151 is guided by the main body side rail 81 and the guide rail 96 continuous to the front side, and is manually pulled out from the molding machine main body 2 onto the carriage guide 85 at the use position. In this state, after the front stopper 106 is moved to the retracted position, the detachable carriage 151 is removed from the carriage guide 85, and the detachable carriage 151 thus removed is placed on the pedestal portion 163 of the transport carriage 161 and cleared. . Thereafter, the front stopper 106 is disposed at the stopper position, and the side stoppers 111 are respectively rotated and disposed at the down position.

  After the detachable carriage 151 is removed as described above, the rotating plate elevating mechanism 72 is driven again, and the elevating shaft 73 is lowered to an intermediate height position where the rotating plate unit 41 is not pushed up. At the intermediate height position, the upper end portion 73 a of the elevating shaft 73 is inserted into the positioning hole 65, but the upper end surface of the upper end portion 73 a is disposed slightly lower than the step portion 66. As the elevating shaft 73 is lowered, the turntable unit 41 is lowered and the seating plate 67 is seated on the upper end surface of the driving force transmission body 13.

  Thereafter, the rotating disk drive device 15 is driven, the upper main shaft 22 is lowered, and the upper main shaft 22 is inserted into the pressure receiving hole 61 of the rotating disk unit 41, so that the force of the disc spring 26 is used as described above. The turntable unit 41 is held in a state of being biased downward by a predetermined spring force.

  The turntable unit 41 is mounted on the molding machine body 2 by the above mounting mode. In this mounting mode, as described above, the detachable carriage 151 on which the turntable unit 41 is placed is arranged on one side of the molding machine main body 2 so that the main body side rail 81 and the guide rail 96 are continuous. A step of guiding the rails 81 and 96 from the carriage guide 85 at the used position and placing it at the first position in the molding machine body 2, and the turntable unit 41 with respect to the detachable carriage 151 at the first position. , A step of guiding the detachable carriage 151 at the first position by the rails 81 and 96 and pulling it from the molding machine body 2 onto the carriage guide 85 at the use position, and a lowering of the raised turntable unit 41 And the process of mounting the rotating disk unit 41 on the molding machine body 2 by executing these processes.

  Therefore, also in this mounting mode, the molding machine main body 2 can be used as a reference for the height positions of the driving force transmission body 13, the rotary disk unit 41, and the detachable carriage 151 of the molding machine main body 2 in the same manner as the take-out mode. At the same time, the detachable carriage 151 can be positioned in the left-right direction orthogonal to the direction in which the rails 81, 96 extend by the main body side rail 81 and the guide rail 96 that are continuous in the front-rear direction. Thereby, even if the floor surface on which the molding machine main body 2 is installed is inclined, the proper mutual positional relationship of the driving force transmission body 13, the rotary disk unit 41, and the detachable carriage 151 is maintained, and the forklift is used. The fork inserted into the molding machine main body 2 does not interfere with the rotary disk unit or the like as in the case of removing the rotary disk unit 41 from the molding machine main body 2. At the same time, the mutual positional relationship between the key-like power receiving portion 46a of the power receiving body 46 is shifted from the key groove-like driving force transmitting portion 13a of the driving force transmitting body 13, and they do not interfere with each other. Therefore, the mounting operation of the turntable unit 41 including the turntable 42 can be performed smoothly.

  In addition, after the turntable unit 41 is mounted in the above procedure, a post-process for storing the cart guide 85 is performed. In this post-processing, since the front stopper 106 of the carriage guide 85 already arranged at the use position is arranged at the stopper position and the side stopper 111 is arranged at the down position, the bracket 101 of the carriage guide 85 is arranged. Is folded into the storage position, and the carriage guide 85 is rotated downward to be disposed at the storage position, and the drive room cover 115 is attached to the molding machine main body 2. At the same time, before and after the post-processing, various devices that have been removed are attached. Further, the operation of the rotating disk drive device 15, the upper spindle lifting mechanism 25 of the rotating disk support device 21, the rotating disk lifting mechanism 72, and the guide lifting mechanism 121 in the attachment / detachment of the rotating disk unit 41 described above are all operation panels. This is done according to instructions from the worker.

  The rotary plate attaching / detaching support equipment 71 provided in the tableting machine 1 incorporates a rotary plate lifting mechanism 72 in the molding machine body 2, and the rotary plate unit 41 is installed using the rotary plate lifting mechanism 72. The turntable unit 41 that is necessary for attaching and detaching is raised and lowered. Therefore, the turntable unit 41 can be easily raised and lowered by the turntable lifting mechanism 72 without depending on human power. Similarly, the transfer operation of the turntable unit 41 between the detachable carriage 151 and the transport carriage 161 on the carriage guide 85 is not affected by human power based on the raising / lowering of the carriage guide 85 by the guide raising / lowering mechanism 121. And can be carried out easily.

  Furthermore, in the tableting machine 1 provided with the rotary plate attaching / detaching support equipment 71 described above, the cart guide 85 is not installed in the molding machine body 2 every time the rotary plate unit 41 is attached or detached, but instead of the molding machine body 2. It is attached to one side so that rotation is possible, and this cart guide 85 can be selectively arrange | positioned in a use position or a storage position. For this reason, when attaching and detaching the turntable unit 41, handling is easy in that it does not require the trouble of fixing another cart guide to the molding machine body 2. At the same time, since the main body side rail 81 is also fixed to the molding machine main body 2, it is easy to handle in that it does not require the trouble of fixing the main body side rail 81 to the molding machine main body 2 when the turntable unit 41 is attached or detached. is there.

  Moreover, since the carriage guide 85 is stored with the bracket 101 folded in the storage position and the side stopper 111 folded in the down position, the thickness during storage can be made thinner than the thickness during use. For this reason, it is preferable at the point which can make the protrusion width of the drive room cover 115 with respect to the one side used as the front of the molding machine main body 2 small.

  In addition, in a state where the turntable unit 41 is mounted on the carriage guide 85 at the use position via the detachable carriage 151, the carriage guide 85 supported from the lower side by the bracket 101 has a large size of the turntable unit 41 from above. Weight acts. Nevertheless, the carriage guide 85 is maintained in a stable state.

  That is, in a state where the carriage guide 85 is disposed at the use position, the base end portion 101 a of the bracket 101 is fitted inside the receiving metal fitting 90 of the base 86. Accordingly, the base end portion 101a is prevented from sliding down by the bottom wall 90a of the receiving metal fitting 90. In addition, the left and right side walls 90b of the metal fitting 90 prevent the bracket 101 from rotating around the hinge 102. Since the bracket 101 can be reliably held at the use position in this way, there is no possibility that the cart guide 85 at the use position is inadvertently turned downward due to the weight of the turntable unit 41 or the like.

  Further, since the pivot 88 serving as the rotation center of the carriage guide 85 is supported at both ends by an iron end member 86b having high strength, the pivot 88 is divided by the weight of the turntable unit 41 applied to the pivot 88 via the arm 89. The pivot is prevented from being deformed as in the case of being supported. Therefore, the cart guide 85 can be held in a stable state.

  In addition, since the front end surface 101b of the bracket 101 at the use position is engaged with the rear surface of the bracket stopper 104 provided on the back surface portion of the guide plate 95, the bracket 101 and the guide plate 95 are moved by the weight of the turntable unit 41 and the like. The bracket stopper 104 can prevent the front from being lowered. Therefore, the cart guide 85 is held in a stable state, so that the turntable unit 41 can be prevented from falling off the cart guide 85 by any chance.

  In addition, since the pair of left and right front stoppers 106 arranged at the stopper position are connected by the insertion / removal pins 109, the pair of left and right rail installation portions 95a of the guide plate 95 are separated from each other due to the weight of the turntable unit 41 and the like. Opening can be suppressed. Also in this respect, the cart guide 85 can be held in a stable state.

  Further, when the turntable unit 41 is mounted on the carriage guide 85 at the use position via the detachable carriage 151, the detachable carriage 151 or the like is not likely to drop off from the carriage guide 85.

  In other words, since the pair of left and right side stoppers 111 of the carriage guide 85 are disposed at the positions where they are raised, the detachable carriage 151 is prevented from moving in the left-right direction beyond the side stoppers 111. At the same time, the second stopper end 111b of the side stopper 111 is opposed to the axle 152a of the wheel 152 of the detachable carriage 151 from above, so that the detachable carriage 151 is the first stopper end 111a. It is prevented from floating over. Furthermore, since the front stopper 106 of the carriage guide 85 is disposed at the stopper position, the detachable carriage 151 is prevented from dropping forward beyond the front stopper 106. Therefore, even when an earthquake or the like is encountered in a state where the turntable unit 41 is disposed on the carriage guide 85 at the use position, the detachable carriage 151 or the like does not fall off the carriage guide 85.

  Moreover, since the positioning plate is passed through the through hole 49a of the supported portion 49 of the rotating disk 42, the rotating disk unit 41 placed on the carriage guide 85 is positioned on the carriage guide 85. The through hole 49a can be used, and the rotary plate 42 does not require special processing for the positioning.
