Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a main body in which a main shaft is rotatably mounted, a rotary disk is detachably attached to the main shaft, and the rotary disk is driven together with a die or a punch by driving the main disk. The present invention relates to a rotary type powder compression molding machine adapted to rotate.

[0002]

2. Description of the Related Art Conventionally, in a rotary powder compression molding machine for compressing and molding powder in a die attached to a rotary disc when a punch passes between upper and lower rolls, the rotary disc is fixed to a vertical shaft. In general, the rotating shaft is rotated by rotating the vertical shaft. In recent years, in order to improve the cleaning performance of the rotary disk, a rotary disk that can be easily removed from the vertical shaft has been developed.

For example, there is known one in which a rotating disk and a vertical shaft are detachably connected by a large key and a key groove. Specifically, a slide key is attached to the lower surface of the turntable, and a key groove is formed on the upper end side of the standing shaft corresponding to the slide key. The center of each of the slide key and the key groove is made to match the center of the rotary disk and the vertical shaft by the centering pin.

[0004]

By the way, in the above-described structure, in order to raise the rotary disc to the upper part of the vertical shaft, a lifting mechanism for raising and lowering the rotary disc in the vertical shaft is being studied. That is, when the turntable is taken out, the turntable is raised to a position where the engagement between the key and the key groove is released. In combination with such an elevating mechanism, a detachable rail that guides and supports the rotating disc in a slidable manner can be attached below the raised rotating disc. Therefore, it can be easily guided to the outside.

However, at such a lower position of the turntable, since the elevating mechanism is provided in the vertical shaft, if water is used for cleaning, the water will be applied to the elevating mechanism, and the water will be wiped off. There was a problem that it took a long time to dry the watered part. In addition, the powder may adhere to the mounting portion of the rail, and the mounting may take time.
That is, since this type of rail guides and supports the rotating disk, the weight becomes heavy by providing the rigidity. When powder is deposited on the mounting portion when mounting such a rail on the device, the mounting work cannot be performed smoothly because of the powder. Moreover, since the mounting portion is located below the turntable, the operator has to work in a crooked fashion, which requires labor for a simple work.

Further, considering the workability of storing and mounting the rail in the rotary powder compression molding machine, if the length thereof is made substantially equal to the depth dimension of the rotary powder compression molding machine, the rotary disk is a rail. Cannot be carried out of the rotary powder compression molding machine in the state of being guided to. Therefore, for example, a vehicle such as a forklift that carries out a turntable or a suspension device such as a small crane provided in the rotary powder compression molding machine is required for such a thing.

An object of the present invention is to eliminate such a problem.

[0008]

The present invention takes the following means in order to achieve such an object. That is, the rotary powder compression molding machine according to the present invention,

Engagement element ER11a engaging with 0c and 40d, and engagement element E
The operation plate ER11b is provided at the lower end of the R11a to operate the engagement element ER11a. Engagement element E
The tip of the R11a is biased upward by a built-in spring, and the operation plate ER11b can be pulled downward. And the operation plate ER
The width of 11b is substantially the same as the groove width of the guide member ER1, and the length of the 11b is longer than the opening 40b of the pull-out rail 40 and has a rectangular shape in plan view. This operation plate ER11
b is a structure that is substantially thicker than the thickness of the stop plate 40e, and is housed in the groove of the guide member ER1 when the engaging element ER11a is engaged with the first locking hole 40c.

In addition, the roller guide surface ERb on which the roller E1b of the lifting body E1 rolls is located near the projecting side end portion which projects from the frame 1 when connected to the drawer rail 40. An opening ERc through which the roller E1b can pass is provided. The opening ERc is normally closed by a removable lid (not shown). The upper surface of the lid body is flush with the roller guide surface ERb, and is attached so that the traction device main body TDB can be smoothly introduced when it is introduced from the protruding end portion into the extension rail ER. This lid body has sufficient strength to support the lifting body E1 with the rotating disk 3 suspended.

Traction device main body TD constituting the traction device TD
In B, as shown in FIG. 10, a worm and a worm wheel that meshes with the worm are arranged in a case TDBa, and a rack RC1 is provided at an upper end of a rotation shaft of the worm wheel.
A pinion TDBb that meshes with the pinion TDBb is attached to the four roller T so as to surround the pinion TDBb.
DBc is attached to the upper end of the case TDBa. Then, in order to rotate the worm from the outside, the drive shaft T
DBd is projected from the case TDBa. This traction device body TDB is, for example, a ball lock T-shaped pin BRP.
Thus, it can be connected to the flange E1a of the lifting body E1. The ball lock T-shaped pin BRP has a ball urged so as to project to the lower end thereof, and the ball is engaged with the flange E1a so that the traction device body T
The DB is detachably connected to the flange E1a.

With such a structure, when the powder is compression-molded, the lifting body E is placed in the housing portion E22a of the lifting shaft E22.
1 With the roller E1b at the upper end stored, the lifting shaft E2
2 and the lifting body E1 are connected (FIG. 1). In this state, the elevating shaft E22 is lowered to the lowest position, and thus the roller E1b is pressed downward in the storage section E22a. Since the elevating shaft E22 is connected to the motor E21 via the torque limiter, in this pressing state, even when the rotary table 3 rotates and receives pressure from below to above, the elevating shaft E22 does not float up. . Therefore, the rotary disk 3 is pressed against the vertical shaft 2 by the lifting mechanism E, the meshing clutch 51 is engaged, and the vertical shaft 2 and the rotary disk 3 are connected.
It is not necessary to fix the upper clutch plate 51c and the lower clutch plate 51a of the meshing clutch 51 with bolts or the like.

When the drive motor M is energized, the turntable 3 is rotationally driven by the rotation of the vertical shaft 2. Since the meshing clutch 51 connects the turntable 3 and the standing shaft 2 with the plurality of claws 51d engaged with each other,
Even if the load changes intermittently during tableting, the engagement state of the plurality of claws 51d is unlikely to change, so that partial wear does not occur and rattling can be prevented. it can.

Next, when the turntable 3 is removed, as shown in FIG. 9, the upper roll 7 fixed to the upper frame 1b is moved in the rearward direction so that the turntable 3 is raised inside the upper frame 1b. After forming a space that can be moved to.
After the upper roll 7 is moved, when the motor E21 of the lifting device E is energized to rotate in the normal direction, the worm C5 rotates and the worm wheel C1 is rotationally driven. Worm wheel C
When 1 rotates, a screwing force is generated between the female screw portion C1a and the male screw portion E22b, but the movement restricting plate C6 prohibits the worm wheel C1 from moving up and down, that is, in the axial direction of the elevating shaft E22. Therefore, the lifting axis E22
Moves upward. Then, the roller E1 of the lifting body E1
When b reaches the position of the pull-out rail 40, if the raised position is detected by, for example, a limit switch (not shown) and the energization of the motor E21 is stopped, the turntable 3 rises to a predetermined position. In this case, the upper punch 5, the lower punch 6, the guide rail 30, the lowering device 31, and the like are integrally lifted together with the turntable 3. In other words, when removing the turntable 3, it is not necessary to remove the lower punch 6, the guide rail 30, and the lowering device 31 from the turntable 3.

When the rotary table 3 is moved to the predetermined position in this manner, the roller E1b of the lifting body E1 is ready to roll on the pull-out rail 40. Here, the lid (not shown) that closes the portion of the drawer rail 40 is removed. As a result, the lifting rail E is attached to the drawer rail 40.
A space in which 1 can move is formed.

On the other hand, in order to carry out the turntable 3, the drawer extension rail ER is connected to the drawer rail 40 before the elevating body E is moved. The procedure for setting the drawer extension rail ER is as follows. First, the operation plate ER11b is pulled downward to release the engagement between the engagement element ER11a and the first locking hole 40c. At this time, operation plate E
Rotate R11b 90 degrees and slide spacer ER1
By inserting 2 onto the operation plate ER11b, the engagement element ER11a maintains the state of being lowered downward.
Drawer extension rail ER can be easily pulled out. And
When the drawer extension rail ER is pulled out until it is almost directly below the turntable suspension plate HP, which is the first drawer position,
Since the guide member ER1 moves forward in the pull-out rail 40, the engaging element ER11a reaches the position where it engages with the second locking hole 40d. Here, the slide spacer ER12 is pulled out from above the operation plate ER11b, and the operation plate ER11b is rotated 90 degrees to engage the engaging element ER11a with the second locking hole 40d. In this state, the spacer SP is inserted on the upper surface of the drawer extension rail ER, and the spacer SP is fixed to the front surface of the turntable suspension plate HP,
The gap between the turntable suspension plate HP and the extension rail ER is filled. Then, from the upper side of the rotary disc suspension plate HP, the stopper bolt SB fixing the rotary disc suspension plate HP is inserted into the through hole HP1, and the drawer extension rail ER is rotatably attached to the rotary disc suspension plate HP.

After this, a mounting hole (not shown) for the rotary plate suspension plate HP in which the stopper bolt SB was inserted.
Insert the long bolt RB into and pull out the rotary plate suspension plate HP. The turntable suspension plate HP draws the drawer extension rail ER, which is the second drawer position, to a position where it can rotate. In this way, the turntable suspension plate H
After pulling out P, the pull-out extension rail ER is rotated by about 90 degrees to orient the connection protrusion ERa toward the pull-out rail 40. When the rotation of the drawer extension rail ER is completed, the rotation stop pin SPa of the spacer SP is operated to lock the drawer extension rail ER from the rotated position so as not to rotate.

Next, the rotary plate suspension plate HP is pushed back to the frame 1 side, and the connection protrusion ERa is pulled out to the rail 40.
To connect the drawer extension rail ER to the drawer rail 40. Then, the long bolt RB is tightened to fix the rotary plate suspension plate HP at this position, and the stopper extension SB is tightened to fix the drawer extension rail ER to the rotary plate suspension plate HP. In this state, the opening ERc of the drawer extension rail ER is closed by the lid.

Next, the roller TDBc of the traction device body TDB is introduced into the drawer extension rail ER from the protruding end of the drawer extension rail ER (FIG. 10). Then, a drive handle TDBd of the traction device main body TDB is connected to what can be a motor such as a manual handle or an electric hand drill, and the drive shaft TDBd is rotated to move the traction device main body TDB to an appropriate position on the extension rail ER. .
Thereafter, a stopper plate (not shown) for preventing the lifting body E1 and the traction device body TDB from falling off is attached to the protruding end of the drawer extension rail ER.

Moreover, since the elevating mechanism E is provided between the upper part of the frame 1 and the turntable 3, the lower side of the turntable 3 can be washed with water. That is, even if the inside of the device below the turntable 3 is washed with water, the elevating mechanism E is located above the turntable 3 so that water is not splashed. Therefore, cleaning becomes easy.

Further, since the drawer extension rail ER does not take up a lot of space when it is stored and is housed in the rotary powder compression molding apparatus, it can be quickly put in a use form without being transported from another place during use. . Further, in use, since it is rotatably attached to the rotary plate suspension plate HP and then rotated to be connected to the drawer rail 40,
Does not require special tools or devices for support during connection,
Connection work can be facilitated. Further, at the time of use, the drawer extension rail ER is supported by the turntable suspension plate HP at approximately the center in the longitudinal direction thereof, so that the strength required for the cantilever support structure is not required,
Therefore, the weight can be reduced. In addition, even though it projects from the upper frame 1b, since it is fixed to the rotary plate suspension plate HP, it does not vibrate in its width direction, and the rotary plate 3 can be stably and smoothly pulled out to the outside. You can
