Description

[Detailed description of the invention] [Industrial application field] The present invention is a mixer in which a mixing blade is inserted from above into liquid, powder, or other materials to be mixed, and then the container is rotated to perform agitation and mixing. The present invention relates to a container holding device for a mixer that holds a container on a turntable.

[Prior Art] A conventional container holding device of this type has a turntable fixed to a rotating shaft protruding from the upper surface of the mixer main body, a hoop along the outer periphery of the turntable is fixed onto the turntable, and the hoop It is designed to hold the container. The hoop is divided into two parts, one of which is fixed to the turntable and the other is free. One end and the other end of the two-split hoop are hingedly connected to each other, and the other end is configured to be detachable by a connecting means.

[Problems to be solved by the invention] Of course, the above-mentioned container holding device cannot hold containers with a diameter larger than the hoop diameter.
Even if the diameter is smaller than the hoop diameter, it is difficult to hold it securely.

Therefore, the diameter of the container that can be held is limited to almost one type depending on the diameter of the hoop, and if you want to mix in a container with a different diameter, you have no choice but to replace the hoop. .

[Means for Solving the Problems] The gist of the present invention is to provide a container holding device for a mixer configured with a turntable that is rotationally driven by a rotational drive mechanism of the mixer main body. A pair of half-split auxiliary tables are arranged on the table, and only one of the half-split auxiliary tables is fixed on the turntable, and a main hoop is formed along the outer periphery of each of the half-split auxiliary tables. A pair of half-split hoops are separately fixed, and one end of the pair of half-split hoops is hinged to each other, and the other end is coupled with a detachable coupling means, and the other sub-hoop has a diameter smaller than that of the main hoop. and consists of a pair of half-split sub-hoops with a low height, each of the above-mentioned half-split sub-hoops is fixed separately on the above-mentioned half-split auxiliary table in a concentric circle with the above-mentioned main hoop, and is further separated from a vertical plate part and a horizontal plate part. A pair of half-split auxiliary hoops having an L-shaped cross section are removably arranged between the main hoop and the sub-hoop, and the vertical plate portion of each half-split auxiliary hoop has its outer diameter aligned with the inner diameter of the main hoop. The height of the sub-hoop is the same as that of the sub-hoop, and a mounting means is provided between the sub-hoop and the main hoop to detachably attach it to the main hoop. This is a container holding device for a mixer configured to have a width from the periphery to the top of the sub-hoop.

The mixer to which this invention is applied is a type of device that rotates a container placed on a turntable and stirs and mixes liquid, powder, or other materials to be mixed using mixing blades inserted into the container from above. It is.

The rotational drive mechanism has a general configuration including an electric motor, a reduction gear, a control device, and the like. The control device is a device that appropriately controls the rotation speed and direction of the electric motor connected to the turntable.

Further, the stirring blade, which is inserted into the container from above the turntable, is supported by an inverted U-shaped support pipe that hangs down from one lower end. The support pipe is held in an upright state by being fitted onto a holding shaft erected on the mixer main body. The configuration of the mixer is the same as in the conventional example.

It is preferable that the turntable is detachably attached to the rotating shaft of the rotational drive mechanism of the mixer main body. For example, a suitable coupler is provided at the center of its lower part to be externally connected to the rotating shaft. The configuration of the coupler may be of a general type, and can be configured with a tightening screw or the like that is screwed into the side of the cylinder in order to fix the cylinder fitted externally to the rotation shaft and the rotation shaft.

Further, it is appropriate that the halving auxiliary table disposed on the turntable of the container holding device has the same diameter as the turntable. Of course, this is to arrange the halved hoop and halved sub-hoop concentrically at regular intervals, so the shape of the two halved auxiliary tables joined at their diameter-equivalent ends is a planar donut shape. etc. may be used. Moreover, it is not limited to a specific shape as long as it can realize the above purpose.

Further, the means for connecting the half hoops to each other can have any structure as long as it can be connected easily and reliably.

Further, the inner periphery of each of the vertical plate portions of each half hoop constituting the main hoop, each half sub hoop constituting the sub hoop, and each half auxiliary hoop is provided with anti-slip material such as rubber lining.

It is appropriate that the main hoop is approximately twice as tall as the sub-hoop. Further, it is appropriate that the height of the vertical plate portion of the halved auxiliary hoop corresponds to the height of the sub-hoop.

Further, the inner diameter of the main hoop is made to match the outer diameter of the container with the largest diameter among the containers of three different diameters held by this device, and the inner diameter of the sub-hoop is made to match the outer diameter of the container with the smallest diameter. Furthermore, when the above-mentioned half-split auxiliary hoop is oriented upward, that is, with the vertical plate part rising from the horizontal plate part, and a pair of them are joined to each other at both ends, the inner diameter of the vertical plate part is set to the intermediate diameter. shall correspond to the outside diameter of the container.

The means for attaching the vertical plate portion of the halved auxiliary hoop to the main hoop can be of various configurations as long as it is removable and can be securely fixed.

For example, a bolt protruding outward from the inside is arranged in the circumferential and vertical center of the vertical plate part, and on the other hand, in the circumferential center of each half hoop of the main hoop, the upper end through which the bolt can pass is opened. The vertical groove is formed with a slightly larger diameter portion in the middle and at the lower end. In addition, the large diameter part in the middle is placed between the main hoop and the sub hoop with the vertical plate part of the halved auxiliary hoop standing up from the horizontal plate part, and the inner end of the horizontal plate part is placed at the upper end of the sub hoop. If you put
The bolt is configured at a portion where it will be located in the longitudinal groove. In addition, the large diameter part at the lower end will be the same when the vertical plate part of the halved auxiliary hoop is placed in the above position with it hanging down from the horizontal plate part, and the inner end of the horizontal plate part is placed on the upper end of the sub-hoop. It is constructed in the area where the bolt will be located.

[Operation] Since the present invention is configured as described above, it can be used as follows.

First, the container holding device of the present invention is set in the mixer main body in advance. As described above, when the coupler is provided at the center of the lower part of the turntable, it can be coupled to the rotating shaft of the rotary drive mechanism protruding from the upper surface of the mixer main body.

Thereafter, the setting state of the pair of halved auxiliary hoops is determined depending on the diameter of the container in which stirring and mixing are performed by this mixer.

First, when holding a container with the largest diameter that can be held by this container holding device, each of the halved auxiliary hoops should be turned downward, that is, with the vertical plate part lowered from the horizontal plate part, and the main hoop and Place it in the lowest position between it and the sub hoop. In this way, the outer periphery of the vertical plate portion is joined to the inner periphery of the main hoop, and further fixed to the main hoop by the attachment means.

Then, one joint end of the halved hoop constituting the main hoop is opened by opening the joining means, and the target container is placed on the horizontal plate portion of the halved auxiliary hoop. Thereafter, the halved hoop is closed, and the bonded state of both ends is securely fixed by the coupling means. Thus, the target container is securely held by the inner periphery of the main hoop. The support for the container is surface support by the inner periphery of the main hoop, and since the supporting force is not concentrated at one point, there is no risk of deformation even in containers such as paper cans, which are commonly used these days.

After stirring and mixing, the container can be easily taken out by opening the coupling means and opening the corresponding end of the halved hoop.

In addition, when holding the smallest diameter container, loosen the attachment means of the half-split auxiliary hoop that is attached when holding the largest diameter container, raise it as it is, and attach the outer periphery of the vertical plate part to the main hoop. When the horizontal plate portion is joined to the inner periphery of the main hoop and the horizontal plate portion substantially coincides with the upper end of the main hoop, the vertical plate portion is again fixed to the main hoop using the attachment means.

Thereafter, as described above, the corresponding end of the halved hoop constituting the main hoop is slightly opened, and the target container with the smallest diameter is placed inside the sub-hoop, that is, on the halved auxiliary table. The half hoop is then closed again and the closed state of the half hoop is fixed by means of the coupling means as described above. The container is thus held around its outer periphery by the sub-hoop. In addition, in this case, even if the mixed materials such as paint in the container are scattered during the agitation and mixing operation by the mixer, the horizontal plate of the halved auxiliary hoop will prevent the spray from flowing between the main hoop and the sub-hoop. Since they are prevented from falling, they can be prevented from adhering to the inner periphery of the main hoop. Since paint or the like does not adhere to the inner surface of the main hoop, it is possible to prevent errors in center positioning when holding the container.

Finally, when holding a container with an intermediate diameter, the halved auxiliary hoop should be oriented upward, that is, the vertical plate part should stand up from the horizontal plate part, and the outer periphery of the vertical plate part should be joined to the inner periphery of the main hoop. Further, the inner end of the horizontal plate part is placed on the upper end of the sub-hoop, and then the vertical plate part is fixed to the main hoop by means of attachment means.

After preparing in this way, in the same way as above,
The main hoop's halved hoop is slightly opened, and the target container is placed on the horizontal plate of the halved auxiliary hoop. Then close the main hoop in half,
This state is fixed by the coupling means as described above. Thus, the container is securely held by the inner periphery of the vertical plate portion of the halved auxiliary hoop.

Therefore, with this container holding device, any target container can be correctly centered and set.

Further, a bolt 18 facing outward (radial direction) is fixed at the center in the circumferential direction and the vertical direction. In addition, a rubber lining 19 is provided on the inner periphery of the vertical plate portion 14 of each of the halved auxiliary hoops 16, so that when the pair of halved auxiliary hoops 16, 16 are joined at both ends and completely closed, the vertical plate Rubber lining 19,1 of section 14,14
9 was configured so that the inner diameter was 229 mm. When each of the horizontal plate parts 15, 15 is arranged with the outer periphery of the vertical plate parts 14, 14 in contact with the inner periphery of the rubber lining 10, 10 of the main hoop 3, the inner end thereof becomes the half-split sub-hoop 11, The width should be such that it slightly rests on the upper end of 11.

By the way, as shown in FIG. 4, locking longitudinal grooves 20, 20 are formed in the circumferential center of each of the half hoops 4, 4 constituting the main hoop 3, and the locking vertical grooves 20, 20 open at the upper end. , constitute circular bolt engagement parts 21, 21 centered at a point approximately 1/4 of the height from the bottom of the half-split hoops 4, 4, and further approximately 1/4 from the top.
Circular bolt engagement part 2 centered at the height of
2 and 22. The bolts 18, 18 can each be engaged therewith. This engagement is fixed with cap nuts 23, 23.

As shown in FIG. 1, at the center of the lower surface of the turntable 1, there is a cylindrical body 25 and a cylindrical body 25 for externally fitting the coupler 24 onto a rotary shaft that is configured to protrude from the upper surface of the mixer main body (not shown). A tightening screw 26 is screwed into the side of the cylindrical body 25 to fix the rotating shaft inserted into the cylindrical body 25.

In this example, since the configuration is as described above,
A mixer body such as that shown below can be used as described subsequently.

The main body of the mixer that this container holding device targets is:
This is a type of device that rotates a container placed on a turntable and stirs and mixes liquid, powder, or other materials to be mixed using mixing blades inserted into the container from above. A rotating shaft for rotating the mixer is configured to protrude from the top surface of the mixer main body. The stirring blades, which are inserted into the container from above the turntable, are supported by an inverted U-shaped support pipe that hangs down from one of the lower ends, and the support pipe is connected to a holding shaft that stands up on the mixer body. It is inserted and supported.

Therefore, before use, the container holding device is first set in the mixer main body. That is, the cylindrical body 25 of the coupler 24 formed at the center of the lower part of the turntable 1 is externally fitted onto the rotary shaft protruding from the upper part of the mixer main body, and the fitted state is secured by tightening the screw 26.
Tighten and secure.

Thereafter, the installation state of the pair of halving auxiliary hoops 16, 16 on the turntable 1 is appropriately set depending on the diameter of the container whose contents are to be mixed.

First, if the container 27a with the largest diameter that can be held by this container holding device is the object, as shown in FIGS. 1 and 5, each half-splitting auxiliary hoop 16, 16 is
downward, that is, vertical plate parts 14, 14, horizontal plate part 15,
15, and the horizontal plate part 15,
In other words, each of the halved auxiliary hoops 16, 16 is placed in the lowest position between the main hoop 3 and the sub-hoop 12. This is the translation. Next, bolts 18, 1 of each vertical plate portion 14, 14
8 in the lower bolt engaging portion 2 in the locking longitudinal groove 20 formed in each half hoop 4, 4 of the main hoop 3.
1, and tighten and fix in this state with cap nuts 23, 23.

After this, the main hoop 3 is opened, and the locking ring 9 provided on the operating piece 8 formed on the outer periphery of the other end is moved from the hook piece 7 formed on the outer periphery of one end of the half hoops 4, 4. Remove the above half hoop 4,
4 is opened, and the container 27a is placed on the horizontal plate portions 15, 15 of the halved auxiliary hoops 16, 16. Then close the main hoop 3 again, i.e.
The outer ends of the half hoops 4, 4 are butted together, the locking ring 9 is locked to the hook piece 7, and the operation piece 8
Fold the outer end side of the hoop 4 toward the half hoop 4, which is the side far from the hook piece 7. Then, the engagement state between the hook piece 7 and the locking ring 9 is fixed at a point slightly beyond the dead point.

In this way, the container 27a is held with an average holding force over the entire circumference by the rubber linings 10, 10 provided on the inner circumference of the main hoop 3.

In this way, the stirring and mixing operation can be performed while the container 27a is securely held.

After finishing, the container 27a can be easily taken out by raising the operation piece 8 outward, removing the locking ring 9 from the hook piece 7, and opening the half hoops 4, 4.

In addition, when holding the smallest diameter container 27b,
As shown in FIG. 2, the half-split auxiliary hoops 16, 16 in the above state are lifted by loosening the cap nuts 23, 23 screwed onto the bolts 18, 18, and the outer periphery of the vertical plate portions 14, 14 is lifted. are joined to the rubber linings 10, 10 of the main hoop 3, and the horizontal plate portions 15, 15 are aligned with the upper end of the main hoop 3, that is, the bolts 18, 18 are connected to the upper bolt engaging portions 22, 10, respectively. 22, the cap nuts 23, 23 are tightened again to fix the halved auxiliary hoops 16, 16 at this position.

In this state, the operation piece 8 is raised outward, the locking ring 9 is removed from the hook piece 7, and the outer ends of the half hoops 4 are slightly opened, and the container 27b is opened.
are placed inside the half-split sub hoops 11, 11 which are opened at the same time, that is, on the half-split auxiliary tables 2, 2. After that, the outer ends of the half hoops 4, 4 are butted against each other to close the main hoop 3, the locking ring 9 is locked to the hook piece 7 again, and the operation piece 8 is moved to the fixed side as described above. Operate to fold it down. Therefore, the container 27b has each half-split sub-hoop 11, 11.
The rubber linings 13, 13 provided on the inner periphery of the holder ensure that it is held with an average supporting force over the entire periphery.

After this, when the mixer body is stirred and mixed,
Even when mixed materials such as paint are scattered from the container 27b, those droplets are removed by the halved auxiliary hoops 16, 16.
Since it is shielded by the horizontal plate parts 15, 15,
Falling between the main hoop 3 and the sub hoop 12 is prevented, and the rubber lining 1 of the main hoop 3
It is possible to prevent splashes of paint, etc. from adhering to the inner peripheries of 0 and 10. Therefore, in the case described above in which the container 27a is held by the rubber linings 10, 10, there is no risk that the center of the container 27a will be shifted from the center of the turntable 1.

Finally, when holding a container 27c with an intermediate diameter, use the halving auxiliary hoop 1 as shown in FIG.
6, 16 facing upward, that is, the vertical plate parts 14, 14 are raised from the horizontal plate parts 15, 15, and the outer periphery of the vertical plate parts 14, 14 is aligned with the inner periphery of the rubber lining 10, 10 of the main hoop 3. Further, the inner ends of the horizontal plate portions 15, 15 are placed on the upper ends of the respective half sub-hoops 11, 11 of the sub-hoop 12. At this time, the bolts 18, 18 of the vertical plate portions 14, 14 are inserted into the bolt engaging portions 22 in the locking longitudinal grooves 20. At this position, the bolts 18, 18 are tightened with cap nuts 23, 23 to fix them to the main hoop 3. In this way, the halved auxiliary hoops 16, 16 are supported by the main hoop 3 and the sub-hoop 12.

After preparing in this way, in the same manner as in the case described above, the half hoops 4, 4 of the main hoop 3 are slightly opened, and the half-split auxiliary hoops 16, 1 are opened at the same time.
The container 27c is placed on the horizontal plate portions 15, 15 of No.6. In this way, again as described above, the half hoops 4, 4 are closed and fixed in the closed state. Therefore, the container 27c is connected to the halved auxiliary hoop 1.
The inner periphery of the vertical plate parts 14, 14 of 6, 16, that is, the rubber linings 19, 19, ensures that the support is held securely by an average supporting force over the entire periphery.

[Effects of the invention] According to the invention, by appropriately determining the inner diameter of the main hoop, the inner diameter of the sub-hoop, and the inner diameter of the vertical plate portion of the halved auxiliary hoop, containers of three different diameters can be reliably mounted on the turntable. It can be held while aligning with the center. That is, the abutting positions of the outer ends of the halved hoops are the same in all cases, so the center will not shift. Further, in any case, since the container is supported in a band shape over the entire circumference, the supporting force is evened out and the holding is reliable.
Furthermore, even when holding a small-diameter container, it is designed to prevent mixed materials such as paint from entering the container.
When paint or the like is applied to the container support surface, ie, the inner periphery of the main hoop, and the container is supported there, there is no risk of shifting the center of the container from the center of the turntable.

Further, since each member is connected to each other, there is no risk of any component falling off during transportation of this device.
