Description

  The present invention relates to a rotary press provided with a lifter for moving a rotor block of a rotary press (also referred to as a rotary material powder compression molding machine or a tableting machine) that compresses tablets and the like.

  The “rotor block” referred to in the present invention includes an upper arm cam guide, an upper arm rotor, a mortar rotor, a lower arm rotor, and a lower arm cam guide. The upper arm rotor is a rotating disk that holds and rotates the upper arm, the mortar rotor is a rotating disk that rotates and holds the mortar, and the lower arm rotor is a rotating disk that holds and rotates the lower arm. On the other hand, the upper eyelid cam guide is a fixed disk that forms a cam track that restricts the raising and lowering of the upper eyelid that goes around, and the lower eyelid cam guide is a fixed disk that forms a cam track that restricts the raising and lowering of the lower eyelid.

  In recent rotary presses, a configuration in which the rotor block can be removed from the rotating shaft for cleaning and maintenance is increasing. The rotor block usually includes an upper arm guide, an upper arm rotor, a mortar rotor, a lower arm rotor, and a lower arm cam guide. The rotor block is arranged outside the device frame by a lifter comprising, for example, a telescopic support post standing on the support surface of the device frame and a swing arm that extends horizontally from the support post and is rotatable with respect to the support post. It is moved to the trolley, and it is placed on the trolley and transported to a cleaning place or the like. The support surface of the apparatus frame is a plane that supports the rotor block, and the support post of the lifter is a long and heavy object having a height that exceeds at least the rotor block. The procedure for reattaching the rotor block to the rotating shaft is the reverse of the removal procedure.

  The lifter provided on the support surface of the apparatus frame raises the support post as necessary, and attaches the swivel arm to the support post. However, since the high support post is heavy, the assembly of the lifter requires labor and labor. In Patent Document 1, a rotor block (rotary disc) is vertically detachable with respect to a rotating shaft (standing shaft), a lifting mechanism that lifts the rotor block that is disconnected from the rotating shaft, and a lifted rotor block. Disclosed is a rotary press (rotary powder compression molding machine) provided with a guide mechanism that moves horizontally toward the outside of the apparatus frame (frame) and an extended guide mechanism that projects continuously from the apparatus frame to the outside of the apparatus frame. . Here, since the elevating mechanism, the guide mechanism, and the extension guide mechanism can be considered to correspond to a lifter, the rotary press disclosed in Patent Document 1 can be regarded as a configuration in which the lifter is permanently installed in the apparatus frame.

JP 2000-224895 A

  In Patent Document 1, a roller is provided on an elevating body projecting from an upper cam guide, and an elevating mechanism is constituted by an elevating shaft suspended from the ceiling surface of the apparatus frame, and the elevating shaft lower end (housing portion E22b) raised. A specific example is disclosed in which the guide mechanism is constituted by a rail continuous to the rail and the extension guide mechanism is constituted by a drawer rail continuous to the rail. Specifically, the lower end of the lifting shaft of the lifting mechanism is engaged with the roller of the lifting body to lift the rotor block, and the rotor block is then transferred by rolling the roller from the lower end of the lifting shaft of the lifting mechanism to the rail of the guide mechanism. The roller block is moved to the outside of the apparatus frame along the pull-out rail continuous with the rail, and is transferred to the carriage. The rotary press disclosed in Patent Document 1 is excellent in that it saves labor and labor for assembling the lifter, but the following problems can be pointed out in the specific example.

  The rotary press feeds the material powder to each die of the die rotor while rotating the upper iron rotor, the die rotor, and the lower iron rotor in the sealed device frame. Make it. For this reason, in the rotary press disclosed in Patent Document 1, the material powder enters the lifting mechanism, the guiding mechanism, and the extension guiding mechanism housed in the apparatus frame as a state. The guide mechanism is complicated, and the material powder that has entered may remain as it is, which may reduce the cleanliness in the apparatus frame. In addition, if material powder accumulates on the rails constituting the guide mechanism or the extension guide mechanism, or if material powder enters the rollers of the lifting body, smooth movement of the rotor block according to the guide mechanism may be hindered. .

  Since the rotor block is transferred to the carriage, it is desirable that the rotor block can be safely moved out of the apparatus frame. The rotary press disclosed in Patent Document 1 is provided with an extension guide mechanism so that the rotor block can be moved out of the apparatus frame. However, in order to save labor and labor for assembling the lifter, the extension guide mechanism is built in the apparatus frame and is configured to expand continuously to the guide mechanism as necessary. For this reason, the structure of the extension guide mechanism is further complicated, and the problem due to the intrusion of the material powder becomes serious. Further, since the take-out rail constituting the extension guide mechanism is cantilevered by the apparatus frame, it is difficult to safely move the rotor block unless the base of the take-out rail is configured to be quite strong.

  In addition, the rotary press disclosed in Patent Document 1 is a ceiling surface of an apparatus frame for lifting a lifting body by a lifting mechanism or transferring a rotor block lifted by the lifting mechanism to a rail of a guide mechanism or an extension guide mechanism. There is a problem that it must be carried out in the vicinity, which requires a considerable amount of labor, and that, for example, the roller wear is excessive and smooth movement of the rotor block becomes impossible. Therefore, a rotary press was studied in order to solve the problems found in Patent Document 1 described above, while a lifter or a structure corresponding to the lifter found in Patent Document 1 was permanently installed in the apparatus frame.

The result of the study was a rotary press equipped with a lifter that moves the rotor block of a rotary press that compresses tablets, etc., and the lifter can be moved up and down and moved horizontally from the ceiling of the equipment frame. And a swing arm that is pivotally mounted on the support post and pivotable horizontally. The pivot arm is pivotally mounted on the support post and pivotable. is composed of a pivotally mounted has been pivotable second pivot arm is provided with a hook portion which engages from the side the eye portion projecting upwardly from the upper punch cam guide that constitutes the rotor blocks to the second pivot arm, the rotor A restriction hole that fits from above into a restriction block that protrudes upward from other than the center of the upper arm cam guide constituting the block, either the first turning arm or the second turning arm. One or a rotary press provided both. The horizontal position of the eye portion is arbitrary, but considering the stability of the rotor block suspended from the lifter, the eye portion preferably protrudes upward from the center of the upper eyelid cam guide.

  The rotary press according to the present invention is configured so that the support post suspended from the ceiling surface of the apparatus frame can be moved up and down and moved horizontally, and a swing arm that is horizontally swiveled is attached to the support post so as to be hooked. Is brought close to the eye part of the rotor block from the horizontal direction, and the support post is raised and engaged. Thus, the rotor block in which the hook portion of the swing arm is engaged with the eye portion can be moved out of the apparatus frame by increasing the horizontal swing range of the swing arm. The support post is moved horizontally along a moving track provided on the ceiling surface, for example, a rail. The lifter according to the present invention is similar to the lifter in which the support post is set up on the support surface of the apparatus frame and the swivel arm is pivotally mounted. However, the support post according to the present invention is short, so it is light and low in cost, and is suspended from the ceiling surface. Since it can be lowered and installed permanently, there is an advantage that it does not require assembly labor and labor.

  The horizontal movement of the support post and the pivot movement of the swivel arm may be either automatic or manual, but manual is preferable from the viewpoint of simplification of the device configuration and cost reduction. In this case, in order to make it easy to specify an appropriate horizontal position of the support post and an appropriate swing position of the swing arm, the lifter has a post positioning pin that engages with the support post and a movement track of the support post provided on the ceiling surface. An arm positioning pin that is provided at a specific position or that engages with the swivel arm may be provided at a specific position on the swivel trajectory of the swivel arm provided on the support post. For example, the engagement of the post positioning pin with the support post may not be released unless the post positioning pin is operated, or may be released only when the support post is pushed a little harder. In the latter case, the post positioning pin constitutes a moderation mechanism. Since the arm positioning pin is the same as the post positioning pin except that the installation target is the turning track of the turning arm, the description thereof will be omitted.

  As a specific configuration in which the hook part of the swivel arm is brought close to the eye part of the rotor block from the horizontal direction and the support post is lifted and engaged, the hook part includes a mortar-shaped inverted frustum recess opened upward, An insertion groove extending from the horizontal center of the inverted frustum concave portion to the outer edge of the swivel arm, and the corresponding eye portion is an inverted frustum block having an outer surface similar to the inverted frustum concave portion, and the upper guide cam guide The structure supported by the support rod of the insertion groove width protruded upward from the center can be illustrated. In this case, if the support post can be moved horizontally in the direction in which the insertion groove of the hook portion extends, the swivel arm can set the inverted frustum concave portion of the hook portion in the eye portion while avoiding the support rod of the eye portion by the insertion groove. The inverted frustum block can be moved to the lower side, and the inverted frustum recess can be easily engaged with the inverted frustum block from below.

  If the lifter has a restriction hole that fits from above into a restriction block that protrudes upward from other than the center of the upper arm cam guide that constitutes the rotor block, the lifter will act as a detent post. Can do. In the rotary press of the present invention, the lifter is permanently installed using the space above the rotor block having a relatively large space. However, since the above-mentioned space has been conventionally provided with a detent post for the upper eaves block, There is a possibility that the post will interfere, but by making the lifter also function as a non-rotating post in this way, the non-rotating post is omitted and the space above the rotor block is cleared, and the manufacturing cost of the rotary press is reduced. Advantages that can be reduced are obtained.

Li lid, the pivotable first pivot arm is pivotally mounted to the support post, is pivotally attached to the first pivot arm constitutes a pivot arm and a pivotable second pivot arm, the hook on the second pivot arm part you the structure provided with. That is, a turning arm that is bent by the first turning arm and the second turning arm is configured. This bending swivel arm can adjust the direction of the insertion groove of the hook part provided in the second swivel arm according to the horizontal position and horizontal movement direction of the support post, so that the horizontal position and horizontal direction of the support post are restricted. The hook part is brought close to the eye part without being received, so that the engagement becomes easy.

  In the turning arm that bends, the restriction hole may be provided in either the first turning arm or the second turning arm. However, since the powdered material powder may enter the swivel axis, the bending swivel arm can be freely inserted into and removed from the first bearing hole of the first swivel arm and the second bearing hole of the second swivel arm. It is preferable that the first swivel arm and the second swivel arm can be bent by inserting a simple swivel shaft, and the second swivel arm is separated as a normal state to avoid a decrease in the cleanliness of the swivel shaft due to intrusion of material powder. . The swivel shaft, the first bearing hole, and the second bearing hole can be configured freely. For example, the first bearing may be an upper stage, the second bearing may be a lower stage, the second bearing may be a screw hole, and a swivel shaft that is a bolt may be screwed into the first bearing hole from above. Similarly, the first bearing may be an upper stage. The rod-shaped swivel shaft provided with a hook that engages with the upper surface of the first swivel shaft may be inserted into the first bearing from above while the second bearing is in the lower stage.

  In the case of a configuration provided with a flange that engages with the upper surface of the first pivot axis, the flange provided on the pivot shaft has a cam shape with a part cut away, and a flange flange is provided on the upper surface of the second pivot arm. The swivel shaft may be rotated so that the notched portion of the scissors faces the scissor flange, the swivel shaft is inserted into the first bearing hole and the second bearing hole, and then the scissors engage with the scissors flange. Thus, the swivel shaft in which the rod is constrained by the rod flange is not accidentally pulled out at the stage where the rotor block is suspended and moved, and safety when using the lifter can be improved. This improvement in safety is particularly preferable when the horizontal movement of the support post and the horizontal movement of the first and second swivel arms are manual.

  Here, even in a lifter having a bendable swivel arm, a positioning pin as a positioning means can be provided while the horizontal movement of the support post and the swivel movement of the first swivel arm and the second swivel arm are respectively manual. preferable. Specifically, a post positioning pin that engages with the support post is provided at a specific position on the moving track of the support post provided on the ceiling surface, or an arm positioning pin that engages with the first swivel arm is provided on the support post. An arm positioning pin that is provided at a specific position of the swivel trajectory of the first swivel arm provided or that engages with the second swivel arm is provided at a specific position of the swivel trajectory of the second swivel arm provided on the first swivel arm. It is the structure to provide. Since the operation of each positioning pin is the same as described above, description thereof is omitted.

  A lifter having a bent swivel arm can also serve as a detent post as described above. Specifically, a restriction hole that fits from above into a restriction block that protrudes upward from other than the center of the upper arm cam guide constituting the rotor block is provided in one or both of the first turning arm and the second turning arm. It will be. For example, if the first swivel arm and the second swivel arm are not separated, the second swivel arm can be swung unexpectedly if the first swivel arm is provided with a restrictive hole in addition to the configuration in which the second swivel arm is provided with a restricting hole. A restraining means is provided so that it does not. In this case, the restraining means of the second turning arm may be the second restriction hole. However, as described above, in order to avoid the deterioration of the cleanliness due to the intrusion and accumulation of the material powder with respect to the swivel axis, the second swivel arm is separated, and the function of the detent post is controlled by the restriction hole provided in the first swivel arm. The structure which serves also is preferable.

  The present invention is able to provide a rotary press that solves the problems found in Patent Document 1, that is, problems due to intrusion of the remaining amount of powder and complications of the apparatus configuration while the lifter is permanently installed in the apparatus frame. To. The reason why the lifter can be permanently installed in the device frame is the effect of the lifter being constructed by pivotally mounting a swingable arm that can be swung horizontally on a support post that can be lifted and lowered horizontally from a ceiling surface. . This lifter also functions as a detent post that suppresses the rotation of the upper arm cam guide, and realizes permanent installation of the apparatus frame while avoiding complication of the apparatus in the space above the rotor block.

  Even in the lifter of the present invention, the soared material powder adheres to the surfaces of the swivel arm and the support post. However, since these are easy to clean, they are unlikely to reduce the cleanliness in the apparatus frame. In addition, the swivel arm that can be freely bent can be detached and disassembled to prevent the material powder from adhering to the swivel shaft and also prevent the swivel arm from being bent due to the adhering material powder. Eliminate fears. This means that smooth bending of the swivel arm is ensured, and as a result, smooth movement of the rotor block suspended from the swivel arm is realized.

  A feature of the present invention is that the rotor block can be smoothly and safely moved out of the apparatus frame by turning the turning arm. In particular, if the swivel arm can be bent freely, it becomes easier to engage the hook part with the eye part of the rotor block without being restricted by the installation position of the support post and the horizontal movement direction, and the direction in which the rotor block can be moved is free. The degree is greatly improved. As a result, for example, after the rotary block is pulled out to the front of the apparatus frame that is not affected by the compression roller or the like, the rotary block can be moved to the right of the apparatus frame and transferred to the carriage.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an example of the lifter 3 of the present invention, FIG. 2 is a perspective view corresponding to FIG. 1 showing the lifter 3 of this example in which the second turning arm 33 is separated from the first turning arm 32, and FIG. FIG. 4 is a front view of the rotary press 1 showing a state where one revolving arm 32 prevents the upper arm cam guide 21 from rotating. FIG. 4 shows the first revolving arm 32 preventing the upper arm cam guide 21 from rotating about the rotor block 2. FIG. 5 is a perspective view of the lifter 3 showing a state in which the second revolving arm 33 engages the hook portion 34 with the eye portion 22, and FIG. 6 is a second revolving arm 33. FIG. 7 is a partially broken plan view of the rotary press 1 showing a state in which the hook portion 34 is engaged with the eye portion 22, and FIG. 7 is a portion of the rotary press 1 showing a state in which the rotor block 2 is moved out of the apparatus frame 11. FIG. 8 is a broken plan view, and FIG. 8 shows that the rotor block 2 is moved out of the device frame 11. It is a front view of the rotary press 1 showing the state moved.

  As shown in FIGS. 1 and 2, the lifter 3 of the present example includes a support post 31 that can be moved up and down and horizontally moved from a ceiling surface 111 of an apparatus frame 11 of the rotary press 1, and the support post 31. The first swivel arm 32 is pivotally attached to the first swivel arm 32 and is pivotable to the first swivel arm 32. The second swivel arm is pivotable to the first swivel arm 32, and a hook portion is provided at the tip of the second swivel arm. Provided. As a result, the lifter 3 of this example is configured as a swivel arm that is bent by the first swivel arm 32 and the second swivel arm, and is provided on the second swivel arm 33 according to the horizontal position and horizontal movement direction of the support post 31. By adjusting the direction of the insertion groove 342 of the hook portion 34, the hook portion 34 can be brought close to the eye portion 22 and can be easily engaged.

  The support post 31 lowers the metal outer cylinder 315 from the moving base 313 sandwiched by the moving track 311 configured as a pair of rails, and similarly hangs the metal inner cylinder 314 from the outer cylinder 315 so as to be movable up and down. ing. The moving track 311 extends in the left-right direction (see FIG. 6 described later) and is embedded in the ceiling surface 111 of the apparatus frame 11. The moving base 313 is equipped with a lifting motor 317 and a lifting jack 318. The horizontal movement of the support post 31 and the raising / lowering of the inner cylinder 314 are automated by a control signal sent from a control cord 316 connected to the outer cylinder 315, but the horizontal movement of the support post 31 can also be performed manually. For this reason, in this example, from the viewpoint of restricting inadvertent horizontal movement of the support post 31, a post positioning pin 312 is provided near the left end of the moving track 311, and the moving base 313 at either end of the moving track 311 is The post positioning pin 312 is engaged, and the horizontal movement of the moving base 313 is restricted.

  The first swivel arm is a metal bar having a square cross section that is pivotally attached to the lower end of the inner cylinder 314 of the support post 31 via the swivel shaft 321, and moves up and down according to the inner cylinder 314. The tip of the first swivel arm is formed in a U shape in side view, and a first bearing hole 324 is provided in each of a pair of upper and lower support flanges 325. The second swivel arm 33 is connected to the first swivel arm by inserting the connecting end 332 between the support flanges 325, inserting the swivel shaft 35 between the first bearing hole and the second bearing hole communicating with each other. The restriction hole 323 is provided so as to coincide with the turning center line of the first turning arm 32, and the restriction hole 323 is fitted to the restriction block 23 provided on the upper surface of the upper eyelid cam guide 21, so that the upper eyelid cam guide Try to stop 21. Since the horizontal turning of the first arm 32 is manual, an arm positioning pin 322 is provided at the rear end pivotally attached to the support post 31 from the viewpoint of regulating the horizontal turning of the first turning arm 32 inadvertently. The arm positioning pin 322 is engaged with the first swivel arm 32 at an angle to restrict horizontal swiveling of the first swivel arm 32.

  The second swivel arm 33 is a metal rod extending in the thickness between the support flanges 325 at the front end of the first swivel arm 32. The second swivel arm 33 is provided with a hook portion 34 at the front end and a connection end portion 332 provided with a second bearing hole at the rear end. It is said. In this example, the upper hole cam guide 21 is prevented from rotating by the restriction hole 323 provided in the first turning arm 32. For example, the restriction hole 333 is provided on the lower surface of the second turning arm 33, and the restriction hole 333 is provided. It is also possible to prevent the upper eyelid cam guide 21 from being rotated by being fitted to the restriction block 23. The hook portion 34 has a bowl-shaped inverted frustum recess 341 provided from the upper surface to the lower surface of the second swivel arm 33, and an insertion groove extending from the inverted frustum recess 341 in the extending direction of the second swivel arm 33. 342. In this example, a closing lever 334 that assists the turning operation of the second turning arm 33 is provided. The closing lever 334 has a bifurcated portion at the end of the lever body, and one end of the bifurcated portion is pivotally attached to the upper surface of the second turning lever 33. This closing lever 334 prevents the deviation of the inverted frustum block 221 of the eye portion 22 fitted in the inverted frustum recess 341 by opening and closing the insertion groove 342 by a bifurcated portion that is horizontally rotated.

  The second turning arm 33 is connected to the first turning arm 32 (see FIG. 1) or separated (see FIG. 1) by inserting and removing the turning shaft 35 through the first bearing hole of the first turning arm 32 communicated with the second bearing hole 324. (See FIG. 2). In addition to moving the rotor block 2 out of the device frame 11, the second swivel arm 33 can be separated from the first swivel arm 32 when it is not necessary, so that the material powder that has swung up the swivel shaft 35 enters. To prevent it. For this reason, if the intrusion of the material powder does not become a problem, the turning shaft 35 may be left inserted, that is, the first turning arm 32 and the second turning arm 33 may be kept connected. In this case, the upper reed cam guide 21 may be prevented from rotating by using the restriction hole 333 in the second revolving arm 33.

  In this example, in order to prevent the turning shaft 35 from being inadvertently pulled out, the turning shaft 35 can be inserted and removed only when the second turning arm 33 is in a specific positional relationship with respect to the first turning arm 32. . Therefore, the swivel shaft 35 is provided with a cam-like flange 351 having a plan view similar to an oval shape with the edges cut away in parallel, and the first swivel arm 32 is positioned in a positioning hole (not shown) on the bottom surface of the flange 351. The protrusion 326 is provided on the upper surface, and the second swing arm 33 is provided with a flange 335 that is in sliding contact with the upper surface of the upper support flange 325. The turning shaft 35 fits a positioning hole into the positioning protrusion 326 and aligns the cut-out parallel edge with the extending direction of the first turning arm 32 to determine the direction of the flange 351. Thus, if the second swivel arm 33 is orthogonal to the first swivel arm 32, the swivel shaft 35 can be pulled out without engaging the reed 351 with the reed flange 335. If the orientation is not perpendicular to the arm 32, the flange 335 engages with the flange 351, and the pivot 35 cannot be extracted.

The function of the lifter 3 of the present example will be described with reference to a procedure for taking out the rotor block 2 after stopping from the operating state of the rotary press 1. When the rotary press 1 is in operation, the lifter 3 acts as a detent post as seen in FIG. 3 or FIG. Specifically, the second swivel arm 33 is removed, the support post 31 is horizontally moved to the left end of the moving track 311 (the back side in the drawing in FIG. 4), and the first swivel arm 32 is oriented by the engagement of the arm positioning pin 322. And the restriction hole 323 (see FIG. 1) is fitted into the restriction block 23 (see FIG. 5) of the upper collar cam guide 21. The first swivel arm 32 of this example is provided with a restriction hole 323 on the swivel center of the first swivel arm 32, so that an external force is applied to the first swivel arm 32 with the restriction hole 323 fitted in the restriction block 23. There is no risk of accidental turning.
The eye part 22 is provided at the center of the upper eyelid cam guide 21.

  When the rotor block 2 is taken out of the device frame 11, as shown in FIGS. 5 and 6, the second turning arm 33 is connected to the first turning arm 32, and the hook portion 34 of the second turning arm 33 is raised.杵 Engage with the eye part 34 of the cam guide 21. Specifically, in order to release the engagement of the first turning arm 32 with respect to the restriction block 23, the inner cylinder 314 of the support post 31 is raised and the first turning arm 32 is raised. Then, after the support post 31 is horizontally moved to the right end of the moving track 311, the first turning arm 32 and the second turning arm 33 are connected by the turning shaft 35. The horizontal movement of the support post 31 may be after the connection between the first swivel arm 32 and the second swivel arm 33. Further, when the support post 31 is horizontally moved to the right end of the moving track 311, a horizontal distance between the support post 31 and the eye portion 22 is secured, and the hook portion is bent by bending the first turning arm 32 and the second turning arm 33. In addition to easily engaging 34 with the eye portion 22, the rotor block 2 can be easily moved out of the apparatus frame 11 by the horizontal turning of the first turning arm 32 and the second turning arm 33.

  In this example, an eye part 22 is provided at the center of the upper surface of the upper eyelid cam guide 21, and the rotor block 2 is stably lifted. The eye portion 22 of this example supports the inverted frustum block 221 that is a transfer structure of the inverted frustum recess 341 constituting the hook portion 34 with a support rod 222 having a width of the insertion groove 342 that also constitutes the hook portion 34. Structure (see FIG. 4). The second turning arm 33 operates the closing lever 334 to open the insertion groove 342 to approach the eye part 22. At this time, if the inner cylinder 314 of the support post 31 is slightly lowered, the support bar 222 can be passed through the insertion groove 342 without interfering with the inverted frustum block 221. Then, when the inner cylinder 314 of the support post 31 is slightly raised, the inverted frustum block 221 is fitted into the inverted frustum recess 341. Finally, when the closing lever 334 is operated to close the insertion groove 342 again, the engagement of the eye part 22 by the hook part 34 is completed.

  After the rotor block 2 having the eye portion 22 engaged with the hook portion 34 is lifted once to release the engagement with the rotating shaft (not shown), as shown in FIG. And the second swivel arm 33 (that is, bent with respect to the first swivel arm 32), for example, once drawn forward with respect to the apparatus frame 11, and then the arc trajectory (see the broken line spline in FIG. 7). As depicted in FIG. 8, it is horizontally moved to the carriage 4 arranged on the right side of the apparatus frame 11. Here, when the rotor block 2 is moved horizontally, the second turning arm 33 is swiveled while maintaining a straight posture with the first turning arm 32 from the middle. Such posture maintenance of the second swivel arm 33 is realized, for example, by providing an arm positioning pin (not shown) that engages with the second swivel arm on the support flange 325 of the first swivel arm 32.

  The attachment of the rotor block 2 follows the reverse procedure of the removal described above. That is, the rotor block 2 carried by the carriage 4 is lifted by the lifter 3 and horizontally moved to a rotating shaft (not shown) in the apparatus frame 11 while drawing an arcuate track (see FIG. 7). After the rotor block 2 is lowered and re-engaged with the rotating shaft, the second turning arm 33 is further lowered to release the engagement of the eye portion 22 with the hook portion 34, and then the insertion groove 342 is closed by the closing lever 334. Opening and pulling the hook part 34 away from the eye part 22 completes the mounting operation. The lifter 3 pulls out the swivel shaft 35 to separate the second swivel arm 33 from the first swivel arm 32, horizontally moves the support post 31 to the left end of the moving track 311 again, and then the restriction hole of the first swivel arm 32. If 323 is fitted into the restriction block 23 of the upper arm cam guide 21, the operating state of the rotary press 1 can be returned.
