Abstract
Description
[Technical field]
[0001] The present disclosure relates to an agitation stand for agitating a liquid contained in a container. [Background technology]
[0002] Conventionally, for example in the field of printing processes, when it is desired to reduce the consumption of liquids such as paints and inks, the liquids are sometimes dispensed in small amounts from a large tank into a small container such as a pail can and stirred. In addition, the mainstream method of stirring is to use an automatic mixer regardless of whether the container is a large tank or a small container.
[0003] For example, Patent Document 1 describes an agitator that can be easily attached to and detached from a stand provided on the top of a tank. This agitator has a structure specialized for agitation work in large tanks, so when dispensing paint or the like in small containers such as pails and agitating them, it is bulky and lacks maintainability.
[0004] When stirring paint or ink dispensed in a small container, for example, a stirrer with a hand-held handle as described in Patent Document 2 may be used. In this case, the stirrer is held by the worker, so it is small and does not take up much space, making it easy to maintain and usable for stirring small containers dispensed in small portions. On the other hand, the worker must remain standing and hold the stirrer until stirring is complete, making it difficult to leave the machine and less efficient to work with. In addition, it places a heavy burden on the worker's body, causing back pain and other problems.
[0005] Patent Document 3 discloses a stand for holding an agitator for a small container such as a pail can. In the agitator stand of Patent Document 3, the agitator is inserted into the container while the wall surface of the small container is corrected, and agitation is performed, realizing a reduction in the need for manual operation. However, since the stand structure is large, it is difficult to maintain. Furthermore, since it is necessary to insert and remove small containers from the stand, lifting and lowering them manually can easily cause back pain, and this places a heavy burden on the worker's body.

[0011] The following describes the embodiments of the present disclosure with reference to the drawings. However, the present disclosure can be implemented in many different forms, and should not be interpreted as being limited to the description of the embodiments exemplified below. In addition, the drawings may be schematic in terms of the width, thickness, shape, etc. of each part compared to the actual form in order to make the explanation clearer, but these are merely examples and do not limit the interpretation of the present disclosure. In this specification and each figure, elements similar to those described above with respect to the previous figures may be given the same reference numerals, and detailed explanations may be omitted as appropriate.
[0012] In this specification, when describing a mode in which another component is disposed on a certain component, the term "above" or "below" is used, unless otherwise specified, to include both a case in which another component is disposed directly above or below a certain component so as to be in contact with the component, and a case in which another component is disposed above or below a certain component with another component interposed therebetween. Also, in this specification, when describing a mode in which another component is disposed on the surface of a certain component, the term "on the surface side" or "on the surface" is used, unless otherwise specified, to include both a case in which another component is disposed directly above or below a certain component so as to be in contact with the component, and a case in which another component is disposed above or below a certain component with another component interposed therebetween.
[0013] The stirring stand of the present disclosure will be described below. Fig. 1 is a schematic perspective view showing an example of the stirring stand of the present disclosure, and Fig. 2 is a schematic side view showing an example of the stirring stand of the present disclosure.
[0014] As shown in FIG. 1 and FIG. 2, the stirring stand 100 of the present disclosure is a stirring stand for stirring liquid in a container, and has a stand lower part 10 and a stand upper part 20, and the stand lower part 10 is provided so as to be retractable from the stand upper part 20. The stand upper part 20 has a frame body 21, a lifting slider 22 fixed to the frame body 21 and capable of moving up and down by releasing the fixation, an agitator installation part 23 for installing an agitator, and a stand lower part fixing part 24 for fixing the stand lower part 10 at a predetermined position. The agitator installation part 23 is fixed so that the angle with respect to the stand lower part fixing part 24 can be changed. Furthermore, when the lifting slider 22 rises, the agitator installation part 23 and the stand lower part fixing part 24 are arranged to descend. In FIG. 1 and FIG. 2, the lifting slider 22 is connected to the stand lower part fixing part 24 via a pulley 25, a wire 26, and a slider 27. The stand lower part 10 has a mounting platform 11 equipped with wheels 15 on which a container is placed, a cover part 12 that covers the opening of the container during mixing, an operation part 13 that receives an operation of moving the stand lower part 10 by an operator, and a receiving part 14 that receives the stand lower part fixing part 24. When the stand lower part fixing part 24 of the stand upper part 20 is lowered, it engages with the receiving part 14 of the stand lower part 10, thereby fixing the stand lower part 10.
[0015] In this specification, the direction in which the stand lower part 10 is pulled out (towards the operator (frontward)) is defined as the front as shown in Figs. 1 and 2. The left-right direction is defined as the direction when the mixing stand is viewed from the operator's side. In addition, the angle between the front-rear direction and the left-right direction in the horizontal direction is usually 90 degrees.
[0016] 3 and 4 are schematic side views for explaining an example of an operating mechanism of the stirring stand according to the present disclosure.
[0017] First, as shown in FIG. 3(a), the operator pulls out the stand lower part 10 of the mixing stand 100. At this time, the operator can easily pull out the stand lower part 10 from the stand upper part 20 by grasping the handle 13b on the operation part 13 of the stand lower part 10 and pulling it toward himself. Next, the container C is placed on the placement table 11. After placing the container C on the placement table 11, it is preferable to connect an earth wire to the container C. This is to prevent static electricity ignition due to floating conductors during mixing. If the container C has a lid, the lid is removed.
[0018] Next, as shown in Fig. 3(b), the stand lower part 10 is slid and pushed into the stand upper part 20. This causes the container C to be placed into the mixing stand 100. The operator can easily move the stand lower part 10 into the stand upper part 20 by grabbing the handle 13b of the operation part 13 of the stand lower part 10 with his / her hand and pushing it into the stand upper part 20.
[0019] Next, as shown in Fig. 4(a), the lift slider 22 is released from the stand upper part 20. As a result, the agitator installation part 23 on which the agitator (not shown) is installed and the stand lower part fixing part 24 descend under their own weight, and the lift slider 22 is lifted. The agitator installation part 23, which descends under its own weight, moves the tip of the agitator from the opening of the container C to the inside, and fixes the lift slider 22 that has been lifted, thereby fixing the position of the tip of the agitator. In addition, the stand lower part fixing part 24, which descends under its own weight, fits into the receiving part 14 of the stand lower part 10, thereby fixing the stand lower part 10.
[0020] Next, as shown in Fig. 4(b), the cover lid part 12 is slid to cover the opening of the container C, and then the stirrer is operated. The cover lid part 12 is arranged to cover the opening leaving a part of it open so as not to come into contact with the stirrer and the stirrer installation part.
[0021] After mixing, the process is reversed and the container after mixing is collected.
[0022] The mixing stand of the present disclosure has wheels and an operating unit at the bottom of the stand, so that a container can be easily inserted into the mixing stand. In addition, when the mixed container is to be removed, the container can be easily removed by pulling out the bottom of the stand. Therefore, the burden of manual work caused by inserting and removing the container while holding it can be reduced. Furthermore, by releasing the fixation of the lifting slider, the agitator installation part on which the agitator is installed and the stand bottom fixing part are lowered in conjunction with each other, and the agitator can be positioned by fixing the lifting slider. Furthermore, according to the present disclosure, since the agitator is installed and held on the agitator installation part, there is no need to hold the agitator manually, and the machine can be removed. Furthermore, there is no need to use or manufacture a dedicated agitator, and a commercially available small agitator can be used. After mixing, the agitator can be easily removed from the container and the fixation of the bottom of the stand can be easily performed by lowering the lifting slider. Therefore, the burden of manual work can be reduced. Furthermore, the mixing stand of the present disclosure can also accommodate small containers such as pails, and has a simple configuration using a mechanism, so that it is easy to maintain.
[0023] Below, each configuration and characteristic of the stirring stand in this disclosure will be described in detail.
[0024] 1. Top of the stand The stirring stand of the present disclosure has a stand upper part. The stand upper part has a frame body, a lifting slider that is fixed to the frame body and can be lifted and lowered in the vertical direction by releasing the fixation, an agitator installation part for installing an agitator, and a stand lower fixing part for fixing the stand lower part at a predetermined position. Furthermore, the lifting slider, the agitator installation part, and the stand lower fixing part are connected to each other, and are arranged so that the agitator installation part and the stand lower fixing part descend when the lifting slider in the stand upper part ascends. Furthermore, the agitator installation part is fixed to the stand lower fixing part so that the angle with respect to the stand lower fixing part can be changed.
[0025] The lift slider is a member that is fixed to the frame body and can be raised and lowered in the vertical direction by releasing the fixation. The lift slider is preferably arranged in front of the frame body so as to face the front of the operator. In the present disclosure, the lift slider is arranged so that when the lift slider rises, the agitator installation part and the stand lower fixing part move down in conjunction with each other. Also, when the lift slider descends, the agitator installation part and the stand lower fixing part move up in conjunction with each other.
[0026] As shown in Fig. 1 and Fig. 2, the lift slider 22 has, for example, a slider portion 22a and a lift operation portion 22b. The slider portion 22a is fixed to the frame body 21 so as to be liftable and lowerable, and has a function of being able to be released by, for example, an operator pushing the operation portion 22b downward. In Fig. 1 and Fig. 2, the slider portion 22a of the lift slider 22 is preferably connected to the stand lower fixed portion 24 via, for example, a pulley 25, a wire 26, and a slider 27 fixed to the frame body 21. The slider 27 is disposed behind the frame body 21 so as to be able to be lifted and lowered in the vertical direction. The frame body 21 functions as a rail.
[0027] The upper part of the stand has an agitator installation part. The agitator is attached to the lower end of the agitator installation part. When the fixation of the lift slider is released with the agitator installed, the agitator installation part preferably descends under its own weight together with the stand lower fixed part. The descending agitator installation part moves the tip of the agitator from the opening of the container to the inside, and fixes the lift slider that has risen to the top (the position of the lift slider when the stand lower fixed part is engaged with the receiving part), thereby fixing the agitator. The position of the agitator in the container can be adjusted by the angle of the agitator relative to the stand lower fixed part and the fixed position.
[0028] In the present disclosure, since the agitator is fixed to the agitator installation section, there is no need to hold the agitator manually and the agitator can be removed. In addition, there is no need to use or manufacture a dedicated agitator, and a commercially available agitator can be used. The agitator is preferably provided with a function of automatically stopping after a certain period of time, for example, by providing a timer. In addition, the agitator is preferably provided with a function of notifying the operator of the end of the agitation operation, for example, by providing an alarm.
[0029] The upper part of the stand has a lower part of the stand fixing part for fixing the lower part of the stand at a predetermined position. The lower part of the stand fixing part fixes the position of the lower part of the stand in the front-rear direction by fitting with the receiving part in the lower part of the stand. By having the lower part of the stand fixing part, it is possible to prevent a malfunction such as the lower part of the stand sliding forward unintentionally during stirring. The lower part of the stand fixing part in the upper part of the stand and the receiving part in the lower part of the stand are fixed by fitting with each other. As shown in FIG. 1 and FIG. 2, the lower part of the stand fixing part 24 has, for example, a columnar member 24a extending in the vertical direction, and a fitting part 24b fixed to the lower end of the columnar member 24a and having a shape that fits with the receiving part on the surface facing the receiving part. The fitting part may have, for example, a recess on the surface facing the receiving part, and be able to fit with the protrusion of the receiving part. In addition, the fitting part may have a protrusion on the surface facing the receiving part, and be able to fit with the recess of the receiving part. In addition, the columnar member and the fitting part may be separate members or may be integrated.
[0030] As described above, when the lift slider and the stand lower fixed part are connected by a wire and a pulley, the distance that the stand lower fixed part descends (i.e., the distance that the lift slider ascends) corresponds to, for example, the distance between the stand lower fixed part and the receiving part. In addition, the agitator can be positioned at an appropriate position in the container by changing the angle and position of the agitator installation part relative to the stand lower fixed part according to the size of the container. It is preferable that the weight of the agitator installation part, the stand lower fixed part, and the lift slider is such that when the fixation of the lift slider at the top of the stand is released, the agitator installation part and the stand lower fixed part on which the agitator is installed descend under their own weight, and the lift slider is raised accordingly.
[0031] In order to improve workability, the upper part of the stand preferably has a temporary placement part for temporarily placing the lid removed from the container. The temporary placement part can be arranged, for example, on the side of the upper part of the stand. If the upper part of the stand is magnetic, the lid may be fixed by a magnet.
[0032] The upper part of the stand is preferably provided with an earth wire as a member for earthing the container. The earth wire can be connected, for example, to the handle of the container. When stirring a volatile liquid, fires and explosions caused by static electricity of the liquid can be suppressed.
[0033] 2. Bottom of the stand The mixing stand according to the present disclosure has a lower stand portion that is retractable from the upper stand portion, i.e., slidable in the front-rear direction relative to the upper stand portion.
[0034] The lower part of the stand has a platform on which the container is placed and which is equipped with wheels. The platform is in contact with the floor surface by the wheels and can be moved forward and backward along the frame body of the upper part of the stand. The platform preferably has a plurality of columnar members extending vertically and a plurality of columnar members extending horizontally.
[0035] The wheels are preferably fixed wheels. By having fixed wheels, it is possible to move back and forth along the frame body of the upper part of the stand without shifting left and right along the lower part of the stand. Therefore, the container can be placed in a desired position. Here, fixed wheels refer to wheels that can rotate around a horizontal axle but cannot rotate around a vertical axis.
[0036] The lower stand has an operation unit that accepts an operation of moving the lower stand by an operator. As shown in FIG. 1 and FIG. 2, the operation unit 13 is preferably fixed to the front of the lower stand 10. The shape of the operation unit 13 is not particularly limited, but it is preferable that the operation unit 13 has, for example, a first columnar member 13a extending vertically and a handle 13b extending in the left-right direction provided on the upper part of the first columnar member. An operator can easily pull out the lower stand forward by grabbing the handle with his / her hand and pulling it toward himself / herself. On the other hand, the lower stand can be easily moved into the upper stand by grabbing the handle with his / her hand and pushing it toward the upper stand side.
[0037] The lower part of the stand has a cover part that covers the opening of the container during stirring. By covering the opening of the container, splashing during stirring can be prevented. As shown in FIG. 1 and FIG. 2, the cover part 12 is preferably attached to the front of the lower part of the stand 10 so as to be rotatable and slidable in the horizontal direction. For example, the cover part is preferably attached to the first columnar member of the operation part so as to be rotatable and slidable in the horizontal direction. This makes it possible for an operator to place the cover part on the opening of the container without bringing his / her hand close to the opening of the container. The cover part is preferably placed so as to cover the opening of the container with a part left open so as not to come into contact with the agitator and the agitator installation part.
[0038] The stand lower part has a receiving part that receives the above-mentioned stand lower part fixing part. The receiving part is arranged at a position where it can be fitted with the stand lower part fixing part in the stand upper part. As shown in Figs. 1 and 2, the receiving part 14 is preferably fixed to the rear of the stand lower part 10. It is also preferably fixed to the mounting base 11. The shape of the receiving part is not particularly limited as long as it has a shape that can be fitted with the stand lower part fixing part in the stand upper part. For example, as shown in Figs. 1 and 2, the receiving part 14 has a second columnar member extending in the left-right direction, and may have a convex part or a concave part on the surface facing the stand lower part fixing part 24.
[0039] The lower stand part may be connected to the upper stand part so as to be movable in the front-rear direction. This is because the lower stand part can slide along the frame body of the upper stand part without being displaced in the left-right direction. As shown in Fig. 1 and Fig. 2, for example, the lower stand part 10 may be connected to a slider 28 running on a columnar member (rail) that constitutes the frame body 21 and extends in the front-rear direction.
[0040] The lower part of the stand is preferably made of a material capable of earthing the container, for example, a conductive steel material or a material that has been surface-treated with a conductive material.
[0041] The upper or lower stand may have a locking mechanism to lock the container in place.
[0042] 3. Mixer The agitator to be installed in the agitator installation section is not particularly limited, and a commercially available agitator can be used. For example, the agitator described in Patent Document 2 can be used. The type of agitator is preferably changed depending on the type of liquid. When the liquid to be agitated is volatile, an air-driven agitator is preferable. This is because it can be made explosion-proof. The agitator may be connected to earth.
[0043] 4. Container The container is not particularly limited, but a pale can is preferable. In this specification, a pale can refers to a steel container having a capacity of 18 L or more and 20 L or less, as standardized by JIS Z 1620:2020. The inner diameter of the opening of the pale can is, for example, 282 mm or more and 288 mm or less. A pale can generally has a can body formed in a bucket shape and a lid that closes the opening at the upper end of the can body. A handle for carrying the can by hand may be attached to the can body.
[0044] The container contains a liquid. The liquid is not particularly limited, but examples thereof include paint, solvent, chemicals, medicines, etc. The liquid may be a volatile liquid or a non-volatile liquid.
[0045] The present disclosure is not limited to the above-described embodiments. The above-described embodiments are merely examples, and any embodiment that has substantially the same configuration as the technical idea described in the claims of the present disclosure and exhibits similar effects is included in the technical scope of the present disclosure.
