Description

Vortex mixer for stirring paint

Technical Field

The present invention relates to a vortex mixer for generating a vortex of a liquid in a container, and more particularly, to a technique for stirring a paint contained in a container (paint bottle (paint can) or spray can) of a paint used for modeling such as a plastic model.

Background

Conventionally, as an electric device for stirring a content liquid by rotating a bottom of a test tube at a high speed, a vortex mixer has been known, and various products are sold by a plurality of manufacturers as shown in non-patent documents 1 to 3.

The vortex mixer is a device for forming vortex in a liquid in a test tube or a container to stir, and is used for mixing or uniformly developing reagents or is used for mixing multicolor nail polish to blend colors.

The commercially available vortex mixers shown in non-patent documents 1 to 3 have a bowl-shaped member made of rubber mounted at a position offset from the center of a drive shaft of a motor facing upward. The bowl member is operated by driving the motor, and the bottom of the container is pushed against and brought into contact with the bowl member while holding the container with the liquid by hand, thereby rotating the bottom of the container at a high speed. Whereby the liquid in the interior of the container forms a vortex and the liquid is stirred by this vortex.

On the other hand, as shown in patent document 1, there is also known a stirring device for stirring paint or the like contained in a container. Patent document 1 discloses a technique for uniformly stirring a container without involving air therein, and directly stirring the container by placing a stirring head having spiral grooves therein. The stirring device is described as having high usefulness as a stirring device for stirring paint or the like contained in a container such as a small bottle or a can used for an interesting work such as a model in a state of being placed inside the container.

Disclosure of Invention

Problems to be solved by the invention

The applicant of the present application has developed companies that use various tools for modeling such as plastic models. The paint of various colors used for making the plastic model and other models is respectively put into individual paint bottles and stored, and the bottles are opened for use when in use.

There are hundreds of colors on the market, and paint bottles of hundreds of colors or more are stocked according to a model maker (model producer), and a required color is selected from the stock and used by re-capping each time.

In paint bottles which are not used after purchase and which have passed through a long period of time or paint bottles which have passed through a period of time after the previous use, the paint in the paint bottles may be separated, deposited, gelled, or the like, and the paint bottles may not be used directly after the cap is opened. In this case, the paint bottle is simply shaken on the hand and cannot be used, and it is necessary to insert a pen into the bottle for stirring, or to insert a stick, which becomes a stirring rod, into the bottle for stirring.

However, in the case of inserting the pen, the pen must be inserted deeply up to the bottom of the paint bottle, with loss of paint due to the paint adhering to the stem portion of the pen. The same applies to the case where a stick other than a pen is used as the stirring rod.

The problem of such paint loss also occurs in the same manner as in patent document 1 in which the stirring device is directly inserted into the paint bottle. In particular, there are many types of paint bottles, and each time a stirring device is prepared and a stirring head is inserted into the paint bottle to perform stirring operation, a huge burden is imposed on a model maker, and further, it is considered that the stirring head after use is required to be cleaned, which is an unrealistic device.

On the other hand, there has been a discussion of stirring by generating a vortex in the interior of a paint bottle using a vortex mixer as disclosed in non-patent document. However, the conventional vortex mixer is aimed at uniformly developing the dispersion and mixing of the liquid, and it cannot be expected to generate a vortex of the so-called semi-solidified paint, such as separation by stirring, sedimentation, gelation, and the like, and there is a concern that the paint cannot be restored to a usable state again.

Further, in the case of stirring by a conventional vortex mixer, it is necessary to hold the paint bottle by hand while keeping the bottom of the paint bottle pressed against the bowl member. Therefore, the time is limited, and other operations cannot be performed. Especially in the case of a large number of paint bottles requiring stirring, the loss of time is immeasurable. In addition, vibration is transmitted from the paint bottle to the hand, and there is a concern that the model maker will be physically burdened.

Furthermore, even if a vortex mixer is used, the method of forming the vortex varies depending on the holding method or angle of the paint bottle by the model maker, and the stirring operation varies, so that the state of the paint varies. In order to meet the demands of the modeler who is very careful in terms of the state of the paint, it is necessary to positively form a vortex with strong stirring force and to realize stirring with good quality.

On the other hand, in a so-called spray can containing a spray paint, it is also necessary to shake the can vigorously to agitate the spray paint inside during use, and there is a problem similar to that in the case of a paint bottle.

In view of the above problems, the present invention has been made in view of the above problems, and has mainly been directed to a novel technique for stirring a paint contained in a paint bottle or a paint contained in a paint can.

Further, stirring can be performed without opening the lid of the container, and the work for stirring is easy, and no loss of paint occurs. In addition, the occurrence of variation in stirring can be suppressed, and stirring of good quality can be achieved.

Further, according to an aspect of the present invention, occurrence of shaking of the device during stirring can be prevented, and ineffective shaking of the container or tilting of the central axis of the container can be suppressed to maintain an upright state, thereby stably forming a vortex in the content liquid. Further, by suppressing the shaking of the device or the container, the device or the container can perform a higher-speed whirl, and a vortex with a fast flow can be formed, so that more powerful stirring can be realized, and the stirring time can be shortened.

Further, according to an aspect of the present invention, containers having different shapes or different thickness, such as angle bottles, small diameter round bottles, medium diameter round bottles, large diameter round bottles, spray cans, etc., can be held without any attachment, and stably held.

Also, according to an aspect of the present invention, for example, in the case of placing a paint bottle having a high height, the paint bottle can be stably held over a wide range in the high support wall area, and on the other hand, in the case of placing a paint bottle having a low height, by supporting the paint bottle in the low support wall area, a finger which grips the paint bottle can be easily placed. The paint bottle can be easily taken out by pinching with a finger when the paint bottle is taken out after stirring.

Further, according to an aspect of the present invention, the rotation can be performed at an arbitrary rotation speed.

Further, according to an aspect of the present invention, stirring of the container can be automatically stopped, and the burden of the operation for ending the stirring can be reduced.

Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in fig. 1, the vortex mixer 1 of the present invention homogenizes separated, precipitated, gelled, and other paint by swirling (vortexing) the paint inside a paint bottle 60 (container) in which the paint produced by a model such as a plastic model is added to stir the paint.

In addition, depending on the paint, there are paints composed of various kinds of liquids, and paints containing solid components, and various phenomena such as emulsification and dispersion are strictly generated by stirring with vortexes, but in the present specification, the phenomenon including these various phenomena is expressed by the term of homogenization. As the paint contained in the bottle, there are paint, aqueous acryl paint, enamel paint, and the like. The present invention is also aimed at stirring a solvent for diluting a paint or a paint to be sprayed to a spray can for a plastic mold, in addition to a paint to be added to a bottle. The paint bottle may have various capacities of 10ml, 15ml, and 50ml, various bottles such as a corner bottle (corner post), a round bottle (cylinder), and the like, and the present application can cope with these various shapes. The coating materials may be of a single color such as red, blue, or yellow, or may be of a metallic color, matte color, fluorescent color, primer (base of the coating material), or the like, and may have different densities or viscosities.

As shown in fig. 1, the vortex mixer 1 includes: a main body portion 20 accommodating a motor or the like; and a swivel base 30 that is swiveled by driving a motor.

As shown in fig. 2 (a) and 2 (B), the main body 20 includes a rectangular parallelepiped housing 21, and a motor connected to a power source, not shown, is accommodated in the housing 21.

As shown in fig. 1 and fig. 2 (a), an operation switch 29 is provided on the front side of the housing 21. The rotation of the turntable 30 can be started and stopped by operating the switch 29. The motor output can be adjusted by operating the switch 29 to adjust the swing speed of the swing table 30. The spin speed is set to, for example, 200rpm to 2000rpm. By setting the rotation number to 500rpm or more, a vortex capable of stirring and homogenizing the paint can be reliably formed. Therefore, it is preferable to be configured so that the rotation can be performed at 500rpm or more. Further, by providing a timer not shown, the rotation of the turntable 30 may be automatically stopped after a predetermined time has elapsed.

A suction cup or vibration absorbing rubber, not shown, is provided on the bottom surface of the case 21 shown in fig. 1, and the bottom surface of the case 21 is attracted to a table or the like, so that the entire device is prevented from moving during operation, and vibration transmission to the table is prevented by the vibration absorbing rubber. Thus, the stirring work can be performed without using a hand, and the model maker can perform other works.

As shown in fig. 3 (a), the drive shaft 22a of the motor 22 protrudes upward and is coupled to the shaft hole of the first shaft 24a of the eccentric shaft 24. The second shaft 24b of the eccentric shaft 24 is inserted into the inner race of the bearing 44. A washer 32a for preventing the turntable 30 from falling off is fixed to the second shaft 24b by a screw 32 b.

As shown in fig. 3 (a), a fixing hole 34 into which the outer ring of the bearing 44 is fitted is formed in the turntable 30, and the outer ring of the bearing 44 is fitted into the fixing hole 34 of the turntable 30. A small diameter portion 30d is formed above the fixing hole 34, a recessed space 30e is formed above the small diameter portion 30d, and a washer 32a is disposed in the recessed space 30 e. By disposing the gasket 32a above the small diameter portion 30d, the swing table 30 is prevented from falling off upward.

As shown in fig. 3 (a), a disk-shaped weight 33 is formed on the first shaft 24a of the eccentric shaft 24. The weight 33 is disposed on a straight line connecting the first shaft 24a and the second shaft 24b of the eccentric shaft 24 so as to sandwich the first shaft 24a and protrude to the opposite side of the second shaft 24 b. With this arrangement, the first shaft 24a is disposed between the second shaft 24b and the counterweight 33, and the balance between the second shaft 24b and the counterweight 33 is obtained. By this balance, the occurrence of shake of the entire device during the turning operation is prevented.

As shown in fig. 2 (B), the weight 33 is disposed in a circular accommodation space 21a formed in the housing 21. The weight 33 is fixed to the first shaft 24a of the eccentric shaft 24 by a set screw 37 (fig. 3 a). A tool insertion hole 21b is formed in the housing 21, the tool insertion hole 21b being used for inserting a wrench to tighten the loosened set screw 37. The accommodation space 21a is covered with a cover not shown.

As shown in fig. 2 (a) and 2 (B), eccentric shafts 25 and 26 are disposed at two positions offset from the eccentric shaft 24 in the horizontal direction. The distances from the eccentric shaft 24 to the eccentric shafts 25 and 26 are set to be the same.

As shown in fig. 3 (B), the eccentric shaft 25 is configured to have a first shaft 25a and a second shaft 25B, similarly to the eccentric shaft 24 (fig. 3 (a)), and the first shaft 25a is fitted into the inner ring of the bearing 23 fixed to the main body frame 27, while the second shaft 25B is fitted into the inner ring of the bearing 45.

As shown in fig. 3 (B), a fixing hole 35 into which the outer ring of the bearing 45 is fitted is formed in the turntable 30, and the outer ring of the bearing 45 is fitted into the fixing hole 35 of the turntable 30. A small diameter portion 30g is formed above the fixing hole 35, a recessed space 30h is formed above the small diameter portion 30g, and a washer 32c is disposed in the recessed space 30 h. By disposing the gasket 32c above the small diameter portion 30h, the swing table 30 is prevented from falling off upward. The washer 32c is fixed to the second shaft 25b by a screw 32 d. The other eccentric shaft 26 is similar to the eccentric shaft 25, and the description thereof is omitted. The number of eccentric shafts is not particularly limited as long as the turntable can be rotated stably.

As shown in fig. 4 (a), bearings 44, 45, 46 are fixed to the second shafts of the eccentric shafts 24, 25, 26, respectively, and outer rings of the bearings 44, 45, 46 are inserted into the fixing holes 34, 35, 36 of the turntable 30.

As shown in fig. 4 (a) and 4 (B), the turntable 30 is formed in a substantially triangular shape in a plan view, a fixing hole 34 is formed at a position offset from the center of a circular installation table 31 on which a container such as a paint bottle, not shown, is placed, and fixing holes 35 and 36 are formed at positions protruding in both directions from the installation table 31. As shown in fig. 4 (B), the fixing holes 35 and 36 of the turntable 30 are closed by caps 35a and 36 a. The installation table 31 is not limited to a circular shape, and may be rectangular.

As shown in fig. 5, the installation table 31 is formed by a circular rubber sheet 31a on the front surface of the turntable 30, and the holding mechanism 50 is provided so as to surround the installation table 31.

The holding mechanism 50 of the present embodiment is configured to hold a container such as a paint bottle or a spray can, not shown, by a pair of support wall portions 51 and 52. The support wall 51 is formed in a circumferential wall shape erected in the circumferential direction in a plan view so as to cover a substantially half area of the installation table 31. The other support wall 52 is provided to rotate relative to the vertical rotation shaft 53, and is formed in a circumferential wall shape facing the support wall 51. The support wall portions 51, 52 may be configured to rotate together.

The rotation shaft 53 is vertically provided on the turntable 30, and the support wall portions 51 and 52 and the rotation shaft 53 are integrally rotated with the turntable 30. The rotation shaft portion 53 is provided in the vertical direction, so that the container can be held vertically when being pinched by the support wall portions 51 and 52. A plurality of protrusions 51a, 52a are formed on the support wall portions 51, 52, respectively, on the distal end side of the rotating shaft portion 53 side, and the protrusions 51a, 52a are displaced from each other in the vertical direction so as to be movable without interference. As a result, as will be described in detail later, the diameter of the holding space formed inside the support wall portions 51, 52 can be set to be wide.

The pinching portions 51b and 52b are provided at the ends opposite to the protruding portions 51a and 52a of the support wall portions 51 and 52, and the pinching portions 51b and 52b are used to pinch the support wall portions 51 and 52 with fingers to perform a rotational operation, and the holding mechanism 50 is opened. An energizing force mechanism, not shown, for bringing the protruding portions 51a, 52a of the support wall portions 51, 52 into close proximity with each other to bring the holding mechanism 50 into a state of closing, is provided around the rotation shaft portion 53.

A plurality of protrusions 55, 55 for closely contacting the outer peripheral surface of the paint bottle, not shown, are provided on the inner side surfaces of the support wall portions 51, 52. The projections 55, 55 may be formed of, for example, rubber sheets in which small-diameter circular projections are uniformly arranged, and thereby, the paint bottle held by the holding mechanism 50 is prevented from being deviated by vibration, and a vortex can be stably formed.

As shown in fig. 5 and 6 (a) and 6 (B), the support wall portions 51 and 52 of the holding mechanism 50 are each formed with a high support wall region having a high height H1 from the installation table 31 on the side close to the rotation shaft portion 53, and a low support wall region having a low height H2 from the installation table 31 on the side far from the rotation shaft portion 53. In this embodiment, as shown in fig. 5, a certain range on the side close to the rotation shaft portion 53 is set to a height H1, a certain range on the side far from the rotation shaft portion 53 is set to a height H2, and a range to switch from the height H1 to the height H2 is formed as an arc-shaped curve.

Thus, as shown in fig. 6 (a), in the case of placing the paint bottle 61 with a high height, the paint bottle 61 can be stably held over a wide range by the range of the height H1 by being placed close to the rotating shaft portion 53 side. On the other hand, in the case of placing the paint bottle 62 having a low height as shown in fig. 6 (B), the finger 65 gripping the paint bottle 62 can be easily placed by the range of the height H2 without interfering with the respective support wall portions 51, 52. In the same manner as in the case of removing the paint bottle 62 after stirring, the paint bottle 62 protruding above the support wall portions 51 and 52 is pinched by the finger 65 and easily removed.

In the above-described configuration, as shown in fig. 1, the paint bottle 60 is placed in the vortex mixer 1, and the operation switch 29 is operated to start the rotation of the rotating table 30. As shown in fig. 7 (a) to 7 (D), the turntable 30 is supported by the eccentric shafts 24 to 26 and revolves. At this time, the balance weight 33 balances the entire vibration of the device.

As shown in fig. 8 (a), a vortex 64 is formed in the paint 63 in the paint bottle 60 as the turntable 30 rotates, and the paint 63 is stirred and homogenized. The vortex 64 generates a downward flow to suck the supernatant liquid into the bottom of the bottle, and generates an upward flow at the edge (inner wall) of the bottle to curl up the paint 63 accumulated on the bottom of the bottle, thereby forming a flow that circulates up and down.

As shown in fig. 8 (B), the swirl velocity of the swirl table 30 is arbitrarily adjusted in response to the condition of the paint 63, whereby the shape of the swirl flow 64 can be changed. For example, in the case where the coating 63 is completely separated and solidification is considerably performed, the spin speed is accelerated, whereby homogenization can be achieved in a short time.

In addition, during the stirring, the molder does not need to use the hand button vortex mixer 1 or the paint bottle 60, and can perform stirring operation without using hands, and can perform other operations at the same time, thereby efficiently performing plastic molding.

The present invention can be implemented as described above.

That is, as shown in fig. 1, a vortex mixer 1 for stirring and homogenizing a content liquid of a container (bottle or spray can) containing a paint or the like produced by a mold such as a plastic mold includes: a main body portion 20 accommodating a motor; and a swivel base 30 that swivels by driving a motor, wherein the swivel base 30 includes a holding mechanism 50 for holding a container (bottle or can) while maintaining the container in a horizontal state.

More specifically, the present invention relates to a vortex mixer for stirring and homogenizing plastic model paint of all kinds different in particle, density, viscosity, solvent and container used for model production, the vortex mixer being provided with: a main body portion accommodating a motor; and a whirling table which whirls by driving the motor, wherein the whirling table is provided with a holding mechanism for safely and surely holding containers of various sizes and shapes of the paint for the plastic model, and the whirling table can transmit the whirling energy to the paint in the containers without losing.

Thus, by placing the container in the holding mechanism 50 and rotating the rotating table 30, a vortex (vortex) is generated in the content liquid, and the content liquid is stirred by the vortex, so that the content liquid is homogenized. The model maker can efficiently perform plastic model making without homogenizing the content liquid by hand and performing other operations. Further, stirring can be performed without opening the lid of the container, and the stirring operation can be easily performed without any loss of paint. In addition, the occurrence of variation in stirring can be suppressed, and stirring of good quality can be achieved.

As shown in fig. 2 (a), 2 (B), 3 (a), and 3 (B), the turntable 30 is supported by the plurality of eccentric shafts 24 to 26, and a counterweight 33 is provided on at least one of the eccentric shafts, and the counterweight 33 balances the torque generated by the rotation of the turntable 30, thereby suppressing the occurrence of the shake of the entire apparatus.

More specifically, the turntable is supported by the plurality of eccentric shafts, and a counterweight is provided, and the counterweight is optimized to cancel a reaction of centrifugal force generated by high-speed rotation of the turntable and the container, and to suppress vibration and noise of the entire apparatus when rotating from the container having a light weight and a low gravity center to the container having a heavy weight and a high gravity center.

Thus, the occurrence of shaking of the device during stirring can be prevented, and ineffective shaking (vertical and horizontal shaking) of the container or tilting of the central axis of the container can be suppressed, and the container can be stably maintained in a stable upright state, that is, in a state in which the container is stably maintained in a horizontal state, and a vortex can be stably formed in the content liquid. Further, by suppressing the shaking of the device or the container, the device or the container can perform a higher-speed whirl, and a vortex with a fast flow can be formed, so that a stronger stirring can be realized, and the stirring time can be shortened.

As shown in fig. 5 and fig. 6 (a) and fig. 6 (B), the holding mechanism 50 includes: a pair of support wall portions 51, 52; and a vertical rotation shaft portion 53 that connects the support wall portions 51, 52 so as to be rotatable relative to each other, wherein the holding mechanism 50 is configured to hold the container by sandwiching the support wall portions 51, 52 from both sides.

As a more specific aspect, the holding mechanism includes: a pair of support wall portions; and a rotation shaft portion connecting the support wall portions so as to be rotatable relative to each other, wherein the holding mechanism is adapted to the shape of the cylindrical or polygonal bottle by sandwiching the container from both sides by the support wall portions, and the container is easily attached to or detached from the container, and has a strong and stable holding force even when the container is rotated at a high speed.

Thus, the corner bottle shown in fig. 9 (a), the small diameter round bottle shown in fig. 9 (B), the medium diameter round bottle shown in fig. 9 (C), the large diameter round bottle shown in fig. 9 (D), and the container having a different shape or thickness such as a can for accommodating a paint to be sprayed can be stably held without any accessory clamp.

As shown in fig. 5 and fig. 6 (a) and fig. 6 (B), the holding mechanism 50 has the following structure: a high support wall region which is a high support wall portion and is adapted to hold a high-height container; and a low support wall region which is a low support wall portion having a lower height than the high support wall portion and which is adapted to hold a container having a low height.

Thus, as shown in fig. 6 (a), for example, in the case of placing a high-height paint bottle 61, the paint bottle 61 can be stably held over a wide range by the high support wall area, and on the other hand, as shown in fig. 6 (B), in the case of placing a low-height paint bottle 62, by supporting the paint bottle 62 with the low support wall area, the finger 65 that grips the paint bottle 62 can be easily placed. The paint bottle 62 can be easily removed by pinching with a finger 65 when removed after stirring.

As shown in fig. 1, the swing table 30 has an operation switch 29 for setting the swing speed.

More specifically, the stirring machine has an operation switch for performing safe and reliable stirring by changing the rotation speed of the turntable, wherein the container having a heavy mass and a high gravity center can perform low-speed rotation with a low reaction, and the container having a light mass and a low gravity center can perform high-speed rotation with a low reaction.

Thus, the rotation can be performed at an arbitrary rotation speed.

Further, a timer function is provided for automatically performing necessary and sufficient stirring without being restricted by the time until the completion of stirring by rotating the turntable 30 for only a predetermined time, thereby improving convenience in safely stopping.

This can automatically stop stirring of the content liquid in the container (bottle or spout), and can reduce the burden of the operation for ending the stirring.

The radius Sr of the turntable 30 shown in fig. 3 a (the distance between the centers of the first shaft 24a and the second shaft 24B (the distance between the centers of the first shaft 25a and the second shaft 25B in fig. 3B)) is 3 to 7% of the maximum width 31r of the placement table 31 for placing the container, and is preferably set to 6.04%. In the present embodiment, the radius of gyration Sr: maximum width 31 r=13: 215, the radius of gyration Sr of the gyration base 30 is a ratio of 6.04% of the maximum width 31r of the setting base 31. For example, in the case where the setting table 31 is circular, the maximum width 31r is the diameter of the setting table 31, in the case where the setting table 31 is square, the maximum width 31r is the width (vertical width or horizontal width) of the setting table 31, and in the case where the setting table 31 is rectangular, the maximum width 31r is the dimension of the long side of the setting table 31.

Accordingly, by ensuring that the radius of gyration Sr is small for various types of containers that are supposed to be placed on the installation table 31, the containers can be swirled without greatly swinging (with small vibration) in the horizontal direction. If the radius of gyration is large, the container may tilt and topple due to inertia or may not form a stable vortex due to the tilting, because the container swings largely in the horizontal direction. In addition, particularly in the case of performing high-speed rotation, if the movement of the container in the horizontal direction is large, a large centrifugal force is generated, and the container cannot be sufficiently supported, and a need to use a hand button is also generated.

The present invention is based on the problem that the present invention is different from a device such as an oscillator for the purpose of simple stirring in that the rotation radius is reduced by allowing the container to rotate at a high speed while pressing the container to move in the horizontal direction. For example, in the enamel paint to which a small angle bottle as shown in fig. 9 (a) has been added, in the case where the inside is separated and has been semi-cured, stirring and mixing must be performed by inserting a stirring rod or the like. Even in this case, by reducing the radius of gyration, high-speed gyration can be realized, and thus, vortexing can be reliably generated, and the enamel paint can be restored to a usable state. Stirring the semi-cured coating material to be reusable as described above is a technique which has not been realized by conventional shaking machines. In addition, by changing the rotation speed, the stirring can be optimally performed in accordance with the state of the paint, and the stirring device is advantageous over the conventional device for simply stirring.
