Description

  The present invention relates to a paste kneading defoaming apparatus and a paste container holder in the paste kneading defoaming apparatus.

  For example, a paste material such as a solder paste applied to the surface of a printed circuit board by a screen printer, a paste material used in the electronic industry such as conductive ink, and a paste preparation for a paste in a medical field is sufficiently kneaded, It is required to be used in a defoamed state.

  At present, various types of paste kneading and defoaming apparatuses for performing paste material kneading and defoaming processes have been proposed. Some types of such paste kneading and defoaming apparatuses are shown in FIG. As shown in the figure, a paste container holder 70 is rotated around a rotation driving rotary shaft 20 extending around the revolution driving rotary shaft 11 while being revolved around the revolution driving rotary shaft 11 while being revolved around the revolution driving rotary shaft 11. The cylindrical paste container 60 containing the paste to be kneaded is detachably held by the paste container holder 70 via the adapter 71 in a state where the central axis thereof coincides with the rotation axis 20 for rotation. It is configured to be. In the paste kneading defoaming apparatus shown in FIG. 10, the basic configuration other than the paste container holder 70 is the same as the paste kneading defoaming apparatus (see FIG. 1) according to the present invention to be described later. The description of the specific configuration is omitted, and the same components as those shown in FIG.

  Thus, since the paste container 60 has various configurations depending not only on the size but also on the manufacturers that manufacture the paste container 60, the paste container 60 is held and fixed by the paste container holder 70. However, there is a problem that it is necessary to prepare adapters 71 for each capacity and for each manufacturer.

  For such a problem, for example, a paste container accommodated in a bottomed container body having an open end is pushed from above with a pressing material, and the paste container is placed between the pressing material and the bottom surface of the container body. There has been proposed a holding and fixing method using an adapter configured to be held and fixed (see Patent Document 1).

  However, in the paste kneading device configured to rotate while revolving the paste container, it is necessary to be held and fixed with a sufficient holding force around the rotation driving rotation shaft. There is almost no force to hold the paste container around the rotation axis of rotation for rotation, so to speak, the paste container is held and fixed only by the frictional force between its bottom surface and the lower surface of the adapter. There is a problem that it is difficult to stably hold the paste container.

  As described above, in the paste kneading and defoaming apparatus, there is a strong demand for development of a so-called “universal adapter” corresponding to paste containers of various sizes.

  As shown in FIG. 2, the container holder 30 includes a substantially bottomed cylindrical holder body 31 having a space for receiving a cylindrical paste container 60, and container holding and fixing means 35 provided inside the holder body 31. It is comprised by.

  As shown in FIG. 3, the container holding and fixing means 35 includes, for example, a plurality of, for example, four holding tools 36 arranged at equal angular intervals with respect to the circumferential direction, and all these holding tools 36. The position adjustment mechanism 40 is configured to adjust the position in accordance with the outer diameter of the paste container 60 by moving all the way in the radial direction.

  As shown in FIG. 4, each holder 36 includes a flat plate-shaped base 37, a columnar column portion 38 that is fixed on one surface of the base 37 and extends in the vertical direction, and The holding portion 39 has a container holding surface 39A having an arcuate cross-sectional shape fixed to the peripheral surface at the tip.

As shown in FIGS. 5, 6 and 7, the position adjustment mechanism 40 is rotated integrally with the manual rotation shaft 41A in a locked state by a lock mechanism described later, and is manually rotated in a unlocked state. A manual rotating body 41 provided to rotate independently of the shaft 41A and the holder main body 31 and an inner surface of the bottom wall of the holder main body 31, respectively. And a fixed disk 42 formed with a plurality of linear grooves (in this embodiment, cross-shaped grooves) 42A that extend in a straight line, and the fixed disk 42 is connected to a manual rotating body 41. A plurality of spiral grooves 45 </ b> A, each provided so as to rotate in a plane perpendicular to the rotation center axis B and extending in a spiral shape from the outer peripheral edge portion toward the rotation center axis B, are fixed at the outer peripheral side ends. Circle 42, and a rotating disc 45 formed so as to be positioned corresponding to the linear concave groove 42A. On the rotating disc 45, a paste container mounting table 48 is provided in the rotating disc 45. It arrange | positions in order to hide the spiral groove 45A.
In the paste container mounting table 48, a linear through groove 48 </ b> A extending radially inward is formed at a position opposite to the linear concave groove 42 </ b> A in the fixed disk 42.

  Each holder 36 is movably accommodated in a linear groove 42A of the fixed disk 42 so that the base 37 faces the rotation center axis B, and the column portion 38 is placed in the linear groove 42A. It is arranged in a state of being inserted into the spiral groove 45 </ b> A of the corresponding rotating disk 45, and the lower surface of the rotating disk 45 is in a state where the axial movement of the holder 36 is prohibited.

As described above, the manual rotating body 41 is provided with a lock mechanism that holds the rotational position.
The configuration of the locking mechanism will be described. As shown in FIG. 8, a rotation center shaft B having a fixed gear 51 fixed to the manual rotation shaft 41A and a gear portion 52A meshed with the fixed gear 51 at the tip portion. A locking member 52 that is rotatable around a fulcrum 54 that extends in the parallel axial direction and that has a base end 52B projecting radially outward from the outer peripheral surface of the manual rotating body 41; And a spring material 55 that urges 52 to mesh with the fixed gear 51.
In this lock mechanism 50, the lock member 52 is engaged with the fixed gear 51 fixed to the bottom of the holder main body 31 by the urging of the spring force F by the spring material 55, so that the rotation position of the manual rotating body 41 is held. Although the state is maintained, the lock member 52 is rotated around the fulcrum 54 by pushing the base end portion (protruding portion) 52B of the lock member 52 inward, and the lock by the meshing with the fixed gear 51 is released, As a result, the manual rotating body 41 can be rotated independently of the holder main body 31.

  In the above, the rotation speed of the rotation bar 15 (revolution speed of the paste container 60) can be adjusted within a range of 400 to 2000 rpm, for example, and the rotation of the rotation bar 15 causes the container holder 30 to be rotated. The rotation speed (the rotation speed of the paste container 60) is set to be about 1/2 to 1/5 of the rotation speed of the rotation bar 15, for example.

Hereinafter, the operation of the paste kneading defoaming apparatus will be described.
First, the method for holding and fixing the paste container 60 will be described. In the state where the paste container 60 containing the paste to be kneaded is inserted into the holder body 31 and placed on the paste container placement table 48, the lock member 52 is placed. The base end portion 52B of the lock member 52 is released inward to release the locked state, and the manual rotating body 41 is rotated in a predetermined direction while the base end portion 52B of the lock member 52 is being pressed, whereby FIG. As shown, the rotating disk 45 is rotated independently of the holder body 31 as the manual rotating body 41 rotates. At this time, since the fixed disk 42 (linear concave groove 42A) is in a fixed state, the inner circumferential surface of the spiral groove 45A in the rotating disk 45 in which all of the four holders 36 are rotated. Under the action, they are moved to the radially inward side by the same amount of movement. That is, the support 37 in each holder 36 receives a force inward in the radial direction by the action of the inner peripheral surface of the spiral groove 45 </ b> A due to the rotation of the rotating disk 45, whereby the base 37 is fixed to the fixed disk 42. It moves toward the radially inward side along the linear concave groove 42A.
All of the four holders 36 are locked by releasing their hands from the base end portion 52B of the lock member 52 in a state where the positions of the container holding surfaces 39A are adjusted so as to contact the outer peripheral surface of the paste container 60. In this state, the rotational position of the manual rotating body 41 is held, whereby the paste container 60 is held and fixed by the container holder 30.

After the paste container 60 is held and fixed to the container holder 30 as described above, when the drive motor 10 is driven, the revolving drive rotating shaft 11 is rotated and the rotating bar 15 fixed thereto is moved in the horizontal plane. , And is driven to rotate about the revolution center axis A. The rotation of the rotary bar 15 becomes smooth and stable by appropriately setting the distance from the revolution center axis A of the weight balancer 13. On the other hand, the rotation speed of the rotation bar 15 is monitored by a speed detection means (not shown), and the rotation speed of the rotation bar 15 is adjusted to an appropriate magnitude based on a detection signal from the speed detection means.
As the rotary bar 15 rotates, the power of the drive motor 10 is transmitted to the rotation drive rotation shaft 20 by the power transmission mechanism, and the rotation drive rotation shaft 20 is rotated about the rotation center axis B. As a result, the container holder 30 and the paste container 60 fixed to the rotation driving rotary shaft 20 rotate around the rotation center axis A while revolving around the rotation center axis A, and accordingly, in the paste container 60. This paste is sufficiently kneaded and defoamed by being subjected to the action of the rotational motion at the same time as being subjected to the centrifugal force due to the revolution motion.

  Thus, according to the paste kneading and defoaming apparatus having the above-described configuration, all the four holders 36 are moved together in the radial direction by the position adjusting mechanism 40, so that, for example, a paste container Without using an adapter or the like corresponding to the size of 60, the paste container 60 is in a state where the central axis thereof coincides with the rotation central axis B, and the arc-shaped container holding surface 39A in each of the four holders 36. Therefore, the paste container 60 can be securely held and fixed with a sufficient holding force against the centrifugal force, and the size (outside diameter dimension) of the paste container 60 is restricted. Is substantially eliminated, and various sizes, specifically, for example, those having an outer diameter of 30 to 75 mm (corresponding to a capacity of 10 to 250 cc). It can be configured as being, it is possible to obtain a high versatility.

  When the paste container 60 is held and fixed to the container holder 30, the rotating disk having the spiral groove 45A is formed as long as the manual rotating body 41 is unlocked and the manual rotating body 41 is rotated. 45 can be rotated independently in a state where the fixed disk 42 in which the linear concave groove 42A is formed is fixed, and can move all the four holders 36 in the radial direction. 60 can be held and fixed very easily and reliably, and, for example, during the kneading and defoaming process, the manual rotating body 41 is locked with respect to the holder body 31 so that the rotational position is maintained. Therefore, the state in which the paste container 60 is held and fixed by the container holding means 35 can be reliably maintained, and the intended kneading and defoaming process can be reliably performed. Kill.

As mentioned above, although embodiment of this invention was described, this invention is not limited to said embodiment, A various change can be added.
For example, the position adjustment mechanism has a configuration in which a linear concave groove that accommodates the base of the holder is formed on the inner surface of the bottom wall of the holder body, instead of using a fixed disk in which a linear groove is formed. Even if it is done, the effect similar to the said structure can be acquired.
Moreover, the number of holders is not particularly limited as long as it is at least two or more.

Furthermore, in the paste kneading and defoaming apparatus of the present invention, for example, the length of the rotating bar, the size of the angle formed by the revolution driving rotation shaft and the rotation driving rotation shaft (center axis of the paste container), The fixing position of the container holder and the like are not particularly limited, and can be appropriately changed according to the type of paste material to be kneaded and other conditions.
Further, instead of the rotating bar, other revolving rotating bodies such as a rotating table can be used, and a plurality of container holders can be provided.

  The present invention can be suitably applied to, for example, kneading and defoaming of soldering solder paste, and preparation (kneading) of a paste-like medicine in a pharmacy, for example.
