Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mixing device for stirring and mixing putty when performing putty construction for the purpose of groundwork adjustment, for example, in interior work and painting work.
[0002]
[Prior art]
Generally, when interior construction such as wallpaper pasting is performed, putty application work for the purpose of adjusting the unevenness of the base has been performed as the base. There are mainly paste-type and powder-type putty for base preparation, but at present, powder-type putty is often used because of the shortening of construction period, fraying and ease of carrying.
[0003]
This powder type putty is used after a powdery putty (putty powder) and water are stirred and mixed and kneaded and adjusted to an appropriate viscosity. For stirring and mixing, put putty powder and water into a metal or plastic container such as a bucket, attach the stirring blade to the rotating shaft of the electric drill, and the operator holds the stirring blade in the container with the electric drill. The putty powder and water were mixed and kneaded with a stirring blade by driving the drill and rotating the rotating shaft. In addition, the operator himself has been performing the mixing work directly using tools such as a putter and rubber spatula.
[0004]
At present, however, the mixing work is mechanized using an apparatus for the purpose of shortening the putty adjustment work and reducing the burden on the worker, and more uniform putty mixing. As a conventional mixing apparatus, a container such as a bucket is placed and fixed on a rotary table, the table is rotated in a horizontal direction by a driving mechanism such as a motor, and a stirring blade attached in an inserted state in the container is shaken. There is a configuration in which the putty powder and water in the container are agitated and mixed by relative movement between the rotation of the container and the oscillation of the stirring blades, and kneaded until an appropriate viscosity is obtained.
[0005]
[Problems to be solved by the invention]
Usually, a commercially available powdery putty is about 4 to 5 kg in one bag, and the mixing operation is generally carried out in units of one bag, so the mixing device is also one bag (as 5 kg) putty powder. It is designed to be able to set a container (bucket) of about 14L enough to mix water with water.
[0006]
However, depending on the site, only a small amount of putty may be required. At this time, if mixing of a small amount of putty powder and water is performed in a large-diameter container using the mixing device as described above, the container is rotated and stirred. Since the material does not spread over the range of relative motion with the rocking of the tool, it is very difficult to mix the putty uniformly and knead it to the desired viscosity. Eventually, the worker himself agitated with a patevera etc. or used an electric drill. Accordingly, problems such as an increase in the burden on the operator and non-uniformity of putty mixing again occur despite a small amount of putty adjustment, leading to a reduction in work efficiency as a whole of the putty construction process.
[0007]
In view of the above problems, an object of the present invention is to provide a mixing apparatus that can uniformly and efficiently stir and mix even a small amount of putty, as well as usually stir and mix in units of putty.
[0008]

The first stirrer is integrally provided with the first transmission means at the pivot, and the second stirrer is integrally provided with the second transmission means at the pivot.
[0010]
According to a third aspect of the present invention, there is provided the mixing apparatus according to the first aspect, wherein the first transmission means and the second transmission means are exchangeably mounted on a pivotal support portion of a common stirring tool. It is configured as a separate attachment.
[0011]
According to a fourth aspect of the present invention, there is provided a mixing apparatus according to the first aspect of the present invention, wherein the rocking shaft includes a protruding portion protruding in the radial direction, and the first transmission means and the second transmission means. Each of which includes a socket portion that fits on the swing shaft, and engages the socket portion of the first transmission means with substantially no play to allow the swing motion of the swing shaft within the predetermined angle range. A first hole is provided for transmission to the agitator, and the socket portion of the second transmission means is engaged with the protrusion with play to transmit the oscillating motion of the oscillating shaft to the agitator within the narrow angle range. The play mechanism is formed as a long hole extending in the circumferential direction of the swing shaft.
[0012]
Furthermore, the mixing apparatus according to the invention described in claim 5 is the mixing apparatus according to claim 1, wherein the holding means includes a first holding member and a second holding member, and the first holding member is the first holding member. Fixed to the rotary table to hold the container having a diameter larger than that of another container, and the second holding member can be attached to and detached from the rotary table inside the first holding member to hold the other container. It can be attached to.
[0013]
The mixing apparatus according to claim 6 is the mixing apparatus according to claim 1, wherein the holding means includes a first holding member and a second holding member, and the first holding member is the another container. The second holding member can be immersed in the table surface of the rotary table inside the first holding member to hold the other container. It is something that is projected.
[0014]
In the mixing apparatus of the present invention, the holding means for detachably holding the large-diameter container on the rotary table can detachably hold another small-diameter container via the auxiliary holding means, and the stirring tool is large. Since the rocking transmission means for rocking in a constant angle range in the diameter container can swing the stirring tool in a narrow angle range matched to the small diameter container by the second transmission means, for example, a large diameter container However, in the mixing apparatus according to the present invention, a small amount of putty powder, which is conventionally manually mixed in the mixing apparatus of the present invention, is mixed using a small-diameter container. This can be carried out satisfactorily within a range in which the relative movement between the container rotation and the stirring tool swing is reduced.
[0015]
Therefore, when the mixing device according to the present invention is used, even when a small amount of putty required for construction is used, a small amount of putty powder and water can be uniformly and efficiently stirred and mixed, and the burden on the operator is reduced. The efficiency of the whole process can be improved.
[0016]
It should be noted that the second transmission means of the oscillation transmission means of the present invention is for the oscillation motion within a certain angular range of the oscillation shaft transmitted to the agitator by the first transmission means during the agitation and mixing in the large-diameter container. Thus, at the time of stirring and mixing in the small-diameter container, the swing angle range of the swing shaft is narrowed and transmitted to the stirring tool so as to correspond to the small-diameter container.
[0017]
That is, as shown in FIG. 4, the range D of the swinging motion in the large-diameter container of the stirrer in which the swinging motion of the original swinging shaft within a certain angle range is transmitted by the first transmission means is the small-diameter container. The range A × 2 is extra with respect to the required swinging motion range d of the stirring tool. Therefore, the second transmission means adjusts the original constant angle range of the swinging motion of the swing shaft to a narrow angle range in order to narrow the swinging motion of the stirring tool in the small diameter container to the range d. This must be transmitted to the stirrer, but this can be realized by providing the second transmission means with a play mechanism that absorbs the difference between the two angular ranges.
[0018]
Such a transmission means may be either provided integrally with the stirrer or may be configured as an attachment separate from the stirrer. In the former case, separate first stirrer and second stirrer provided with first and second transmission means are prepared, and stirring is performed in a large-diameter container with respect to the swing axis. A first stirrer is attached at the time of mixing, and a second stirrer is attached at the time of stirring and mixing in a small-diameter container.
[0019]
In the latter case, the first attachment provided with the first transmission means and the second attachment provided with the second transmission means are prepared separately, and a common agitation is applied to the swing shaft. The tool is attached via a first attachment when stirring and mixing in a large-diameter container, and is attached via a second attachment when stirring and mixing in a small-diameter container.
[0020]
As described above, the transmission means is provided integrally with the stirrer or configured as an attachment that can be exchangeably attached to the same stirrer. The angle range of the oscillating motion of the stirrer can be changed by simply replacing and attaching the member to the oscillating shaft without the need for complicated and troublesome operations such as adjusting the drive system to be adjusted. It can be easily changed to one corresponding to each diameter container.
[0021]
In addition, as a configuration for attaching these transmission means to the swing shaft, a configuration in which a socket portion provided with a hole for fitting into a projecting portion protruding in the radial direction formed on the swing shaft is provided in the transmission means is simple. is there. The first hole of the socket part of the first transmission means engages with the protrusion part substantially without play, and transmits the swinging motion of the swinging shaft to the stirring tool in the constant angle range. The 2nd hole of the socket part of 2 transmission means shall form an idle mechanism as an elongate hole extended in the circumferential direction of a rocking | fluctuation shaft. Accordingly, since the second hole engages with the protrusion with play, the play portion absorbs the difference between the constant angle range and the narrow angle range, and the swing motion of the swing shaft is reduced in the narrow angle range. Will be transmitted to the stirrer.
[0022]
In addition, as a holding means having an auxiliary holding means for holding the outer bottom portion of the container on the rotary table in a detachable manner and holding another small-diameter container, a first holding for holding a large-diameter container is provided. The structure which consists of a means and the 2nd holding means for hold | maintaining another container with a small diameter is mentioned. If the holding means has a shape that matches the outer bottom portion of the container to be held, the second holding means for the small-diameter container is smaller than the first holding means and can be installed on the inside thereof.
[0023]
Therefore, the second holding means is not configured to be removed and replaced with the first holding means, but the first holding means is fixedly installed on the rotary table. It can be set as the structure attached to a rotary table inside without removing. This shortens the work time by the amount that does not require the trouble of removing the first holding means. In this case, if the second holding means is detachably attached to the rotary table inside the first holding means, the second holding means can be selected according to a plurality of different small diameter containers. it can.
[0024]
Further, if the second holding means is provided so as to be immersible on the table surface of the rotary table inside the first holding means, without removing or installing the second holding means, Since a large-diameter container or a small-diameter container can be installed, the work process is further simplified.
[0025]
The first holding means may be formed integrally with the rotary table. Examples of such holding means include a bowl-shaped one. In this case, the outer bottom portion of the container is fitted in the side surface of the upper periphery with the rotary table as the inner bottom surface. In this case, if the second holding means that is detachably attached is also shaped like a hook, a locking portion that fits into the inner bottom surface of the first holding means may be formed on the lower surface portion thereof.
[0026]
DETAILED DESCRIPTION OF THE INVENTION
As an embodiment of the present invention, FIGS. 1 to 3 show a mixing apparatus in which a first holding means is formed integrally with a rotary table. FIG. 1 is a schematic configuration diagram of a mixing apparatus according to the present embodiment, and FIG. 2 is a schematic diagram illustrating configurations of first holding means and second holding means of the present embodiment. FIG. 3 is a schematic partially enlarged view for explaining the configuration of the second transmission means and the swing shaft in the mixing apparatus.
[0027]
In the mixing apparatus according to the present embodiment, a rotary table 3 in which a holding frame 5 as a first holding unit is integrally formed on the circumference is placed on a main body 1 in a horizontal plane by a driving device 2 mounted in the main body 1. It is fixedly installed so that it can rotate. The holding frame 5 is an inner periphery that fits into the outer bottom shape of a cylindrical bucket (large diameter container) of about 14 L capacity (not shown) suitable for stirring and mixing 5 kg of putty powder with a required amount of water. It has a shape.
[0028]
In the present embodiment, as the second holding means, a holding frame member 6 having an inner peripheral shape that fits into an outer bottom shape of a cylindrical small diameter bucket 9 having a capacity of 5 L is provided. The holding frame member 6 is provided with locking projections 8 projecting from the lower surface of a beam portion 7 extending in the radial direction that constitutes a part of the bottom surface.
[0029]
The engaging projection 8 is engaged with and engaged with the edge portion of the crosspiece 4 extending in the radial direction constituting a part of the bottom surface of the turntable 3 in a direction opposite to the rotation direction of the turntable 3. The holding frame member 6 is installed on the rotary table 3, and the holding frame member 6 rotates integrally with the rotation of the rotary table 3, and the small-diameter bucket 9 installed on the holding frame member 6 also rotates in the horizontal plane. .
[0030]
Therefore, in this embodiment, the mixing device is a simple process of removing the large diameter bucket from the holding frame 5 of the rotary table 3 and attaching the holding frame member 6 to the rotary table and fitting the small diameter bucket 9 into the holding frame member 6. Can be easily switched to a small amount of putty adjustment mode.
[0031]
Further, in the present mixing device, a swing shaft 10 that swings within a certain angle range by the drive device 2 is provided to project vertically upward at a position away from the rotary table 3 on the main body 1 by a predetermined distance. The rocking shaft 10 has a protrusion 12 projecting in the radial direction at the tip end portion 11, and is a stirring tool equipped with a stirring blade for stirring and mixing the material inside by swinging in a bucket on one end side. The hole of the socket part on the other end side engages with the projection to pivot the stirring tool, and the swinging of the swinging shaft 10 swings the stirring blade on one end side in the bucket transmitted from the socket part. .
[0032]
A first stirring tool (not shown) for use when stirring and mixing with a large-diameter bucket is such that the hole of the socket portion engages with the protrusion 12 without play, and the rocking shaft 10 has a certain angular range. The swinging motion is transmitted to the stirring tool as it is, and the stirring blade on one end side is swung in the bucket. In other words, the constant angular range of the swinging motion of the swinging shaft 10 is within a predetermined distance range D from the wall surface to the opposite wall surface in the large diameter bucket as shown in FIG. Is set in advance.
[0033]
In the present embodiment, another second stirrer 13 having a socket portion 14 on the other end side as a second transmission means for performing a rocking motion corresponding to the stirring and mixing in the small diameter bucket 9 is provided. The stirrer 13 has a stirring blade 16 for agitating and mixing the material in the bucket by swinging in the bucket on one end side like the first stirrer. Thus, a long hole 15 extending in the circumferential direction that engages with the protrusion 12 with play is formed.
[0034]
As described with reference to FIG. 4, the play of the elongated hole 15 is the difference between the swing motion range d of the stirring blade 16 required in the small diameter bucket and the swing motion range D of the stirring blade in the large diameter bucket. The difference in the angular range of the swing motion of the swing shaft 10 corresponding to is absorbed.
[0035]
Therefore, in the mixing apparatus according to the present embodiment, the stirring blade is simply replaced by replacing the first stirring tool with the second stirring tool 13 without performing a complicated and troublesome operation of adjusting the drive system. The range of 16 swinging motions can be easily changed from one suitable for a large diameter bucket to one suitable for a small diameter bucket.
[0036]
Usually, the stirring blade is set so that the edge portion is in contact with the inner surface of the bucket side wall at both end positions of the swing range closest to the bucket side wall surface. This is because if there is a gap between the stirring blade and the bucket side wall inner surface, putty material may stay in the vicinity of the wall surface, and sufficient stirring and mixing may not be performed. On the other hand, in this embodiment, when the stirrer 13 is replaced with a stirrer 13 corresponding to the stir and mix in the small diameter bucket 9, the edge of the stirrer blade 16 is separated from the inner surface of the side wall of the bucket 9 at both ends of the swing range. Or it may be too close.
[0037]
Accordingly, as shown in FIG. 5, the stirring blade 16x is configured to be movable in the horizontal direction with respect to the main body of the stirring tool 13, and the position adjusting mechanism is fixed so that the edge is in contact with the inner surface of the side wall of the bucket 9. 17 is desirable. Thereby, after attaching the stirring tool 13 to the rocking | fluctuation shaft 10, the stirring blade 16x can be adjusted to an appropriate position close to or away from the inner surface of the bucket side wall.
[0038]
In the above embodiments, the first stirrer and the second stirrer, each having a different hole formed in the socket part, are used to perform large-scale putty stirring and mixing in a large diameter bucket, and the small diameter bucket. In the case where a small amount of putty is mixed with a stirrer, the configuration in which both agitators are used properly is shown. It is good also as a structure provided with the formed 1st attachment and 2nd attachment, replacing both attachments according to replacement | exchange of the large diameter bucket and small diameter bucket on a mixing apparatus, and attaching a stirring tool to a rocking | fluctuation shaft.
[0039]
Moreover, in the said embodiment, in order to transmit the fixed angle range of the rocking | fluctuation motion of a rocking | fluctuation axis | shaft to a stirring tool as a narrow angle range, it is the length which extends the hole of the socket part which is a 2nd transmission means to the circumferential direction. A play mechanism that engages the protrusion of the swing shaft with play is provided by making a hole, but in addition, the swing motion of the swing shaft within a certain angular range can be performed without adjusting the drive system. Any configuration that can be changed easily can be used.
[0040]
In the above embodiment, the holding frame member as the second holding means for holding the small diameter bucket is detachably attached to the rotary table. However, the first holding means is attached to the rotary table as the first holding means. It is good also as a built-in type structure protruding inside the holding frame. In this case, it is necessary to have a configuration that does not interfere with the holding of the large diameter bucket by the holding frame 5.
[0041]
For example, as shown in the longitudinal sectional view of FIG. 6 and a plan view seen from above, the holding frame member 26 is detachably fixed to the slit groove 24 formed in the rotary table 23 via the spring mechanism 27 and held. If a large diameter bucket is placed on the frame member 26, the large diameter bucket is held by the holding frame 25 without being affected by the holding frame member 26 if the upper end of the holding frame member 26 sinks to the table surface. . Although the holding frame member 26 is a continuous frame over the entire circumference, the holding frame member 26 may be composed of discontinuous frame members arranged on the circumference.
[0042]
【The invention's effect】
As described above, according to the mixing apparatus of the present invention, not only a normal large-scale putty adjustment, but also a simple operation of lowering and attaching some members, a small amount of putty adjustment that has been a manual operation in the past is required. Since the stirring and mixing operation can be performed with the same apparatus, uniform mixing of a small amount of putty can be performed in a short time, and the burden on the operator can be reduced, and the overall efficiency of the putty construction process can be improved.
