Description

[Detailed description of the invention] [Industrial field of application] The present invention is applicable to stirring and foaming of various liquids used in the fields of civil engineering and construction, and particularly to on-site casting used as elastic interior materials for the floors of buildings. The present invention relates to a stirring and foaming device suitable for use in stirring and foaming urethane foam materials when they are liquid.

[Prior Art] Urethane foams used as elastic materials for the floors of buildings or paving materials for sports facilities include foams formed from other plastics in a liquid mixture of a main agent and a hardening agent. A method has been implemented in which a large number of foamed materials are added and stirred to disperse the above-mentioned large number of foamed materials in the mixed material, thereby attempting to obtain the same effect as foaming the mixed material. This method can be carried out using conventional stirring and foaming equipment.

[Problems to be Solved by the Invention] At present, there is no device that foams a mixture of a base agent and a curing agent while stirring and mixing the mixture as described above.

The method using the foam described above is simple because it requires only a stirring and mixing device, but it is cumbersome in that the foam must be prepared separately and has the drawback of being expensive as a whole. Further, it is not necessarily easy to disperse the foam evenly in the mixture, and even if it is dispersed evenly, there is a problem that it tends to concentrate in one part.

[Means for Solving the Problems] The gist of the configuration of the present invention is as follows: A cart, a turntable mechanism having a turntable disposed on the cart, which rotates the container while holding it; , an agitation control blade that is removably inserted into the container held by the turntable mechanism, which controls the flow toward the rotary foamer described later while agitating the liquid to be agitated as the container rotates. a stirring control blade; and a rotary foamer that is removably inserted into the forward side in the flow direction of the liquid to be stirred in the container held by the turntable mechanism by an arm described below, A pair of collars arranged coaxially at a certain distance above and below, projecting radially from the outer periphery of one of the collars, each bent and extending in the axial direction of the collar from the protruding position of a certain length, A plurality of wires are bent in the direction of the other collar from the radial extension position of the other collar, and their ends are fixed to the other collar, and the wires are bent in a semicircle between the ring-shaped reinforcing members described below. Approximately 1/2 inch from each end of the plurality of wires recessed inward in an arc shape and the portion parallel to the axial direction of the collar of the plurality of wires.
a rotary foamer composed of ring-shaped reinforcing members arranged at positions 3 and 3, and an arm arranged on a bracket arranged on the trolley so that it can be raised and lowered so that its tip can be positioned directly above the container when it is put down. an arm having a rotary drive shaft (described later) hanging from its tip to which a pair of collars of the rotary foamer are externally fixed; This is an agitation foaming device characterized by comprising a rotary drive shaft that can be rotated.

As mentioned above, each of the above-mentioned components is arranged on a trolley, which is convenient for use at a construction site or the like.

The turntable mechanism includes a disc-shaped turntable, a holding means for holding a container placed on the turntable, a drive shaft connected to the center of the lower part of the turntable, and a rotary drive body connected to the drive shaft. It can basically be configured with In either case, known means can be employed.

The rotary drive body may be an electric motor or a suitable engine. With this device,
Since it is necessary to separately drive the rotary foamer, it is preferable that the rotary driver is configured to be used in common with that of the rotary foamer.

The stirring control blades may be of any type as long as they can stir the liquid in the container without leaking to the inner peripheral surface and inner bottom surface and control the flow of the liquid in the desired direction. The agitation control vane can be configured, for example, by being a plate-like member that contacts the inner circumferential surface and inner bottom surface of the container and is arranged so as to intersect the flow of the liquid. A support pipe or the like is fixedly attached to the agitation control vane, and the support pipe is detachably fitted to a support protrusion of the cart or the like outside the container for support.

The rotary foamer is located at the tip of the liquid in the flow direction, and acts to generate a large number of bubbles in the liquid through its rotation.

As mentioned above, the above-mentioned rotary foamer is formed by bending the wire into a roughly tsuzumi (drum) shape.
Bubbles can be generated well.

The rotary foamer is configured such that each of the collars is fitted onto a rotary drive shaft and fixed with screws or the like, and the rotary drive shaft is suspended at the predetermined position in the container by an arm. It is appropriate that a gear device is disposed at the tip of the arm, and that an output shaft hanging from the gear device is used as the drive shaft. It is appropriate that the gear device transmits the rotation of the rotary drive body of the turntable mechanism using a chain, a belt, or the like.

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

First, a container containing a liquid to be foamed by rotation, such as a mixture of a base agent and a curing agent, is set on the turntable mechanism. The container is placed on a turntable and held by a holding mechanism.

Then, set the stirring control blade into the container.
When configured as described above, the stirring control blade is inserted into a predetermined position in the container by engaging the support pipe with a support protrusion that is configured to protrude from the cart.

At the same time, set the rotary foamer in the container.

When configured as described above, the rotary foamer may be fixed to the output shaft (rotary drive shaft) of the gear device, and the arm may be placed in a down position. The rotary foamer can then be inserted into position in the container very easily.

After making preparations in this manner, by driving the rotary drive body, the stirring operation and foaming operation of the target liquid can be reliably performed, and the bubbles can be evenly dispersed in the liquid.

When the rotary drive body is driven to rotate, the turntable rotates in a predetermined direction, which naturally rotates the container held thereon. The liquid inside also begins to rotate in the same direction as the container at approximately the same speed.

The liquid that has started to rotate in this manner is stirred and its flow is changed by the stirring control blades that intersect with the direction of rotation, and is flowed in the direction of the rotary foamer.

As mentioned above, the rotary foamer is rotated by a rotary drive body via a rotary drive shaft, and introduces air into the flowing liquid while rotating and stirring it at high speed, forming fine bubbles and dispersing the air into the liquid. It is used to disperse

As mentioned above, the rotary foamer is constructed in the shape of a drum using wires, so that the liquid can be uniformly foamed at a very high speed.

When the liquid reaches the required foaming state, the operation of the rotary drive body is stopped and the arm is raised to remove the rotary foamer from the container, while also lifting the agitation control blades from the container.

The container can then be picked up from the turntable.

[Example] An example of the present invention will be described below based on the drawings.

As shown in FIGS. 1 and 2, a turntable mechanism, an agitation control blade mechanism, and a rotary foaming mechanism are constructed on the cart 1.

As shown in FIGS. 1 and 2, the stirring control blade mechanism is composed of a stirring control blade 6 and components for inserting the stirring control blade 6 into the container t and holding it appropriately.

First, as shown in FIG. 1, the stirring control blade 6 is formed into a generally L-shaped plate when viewed from the lateral direction. The horizontal plate portion 6-1 has a length approximately corresponding to the radius of the corresponding container t, while the vertical plate portion 6-2 has a length slightly lower than the height of the container t. This stirring control blade 6 is arranged so that the outer end of the vertical plate part 6-2 is in contact with the inner peripheral surface of the container t, and the lower end of the horizontal plate part 6-1 is arranged so as to be in contact with the inner bottom surface of the container t. do. Further, as shown in FIGS. 1 and 2, the vertical plate portion 6-
2 extends from the upper end of the container t in the opposite direction to the rotation direction.
A sector-shaped cover piece 6-3 having a corresponding circular periphery extends from the side in contact with the inner periphery.
This is to prevent the liquid from scattering to the outside during stirring.

As shown in FIGS. 1 and 2, this agitation control blade 6 has a support pipe 7 along the vertical direction on the back side (the side opposite to the side from which the cover piece 6-3 is extended).
be fixed. This support pipe 7 is designed based on the assumption that the stirring control blade 6 is accurately inserted into the container t.
At a height slightly exceeding the upper end of the container t, it extends from that position to above the corner of the trolley 1 (the corner on the opposite side from the engine 5), and is bent downward at this point. The lower end can be removably fitted into a support cylinder 8 protruding from a corner of the truck 1.

Further, as shown in FIGS. 1 and 2, the rotary foaming mechanism includes a rotary foamer 9, an arm mechanism that supports the same, and a rotational force transmission mechanism that transmits rotational force from the engine 5. do.

First, the rotary foamer 9, as shown in FIG.

1, 11, . . . , the portion located between the two reinforcing rings 12, 12 is recessed inward in a semicircular arc shape, and the overall shape is shaped like a drum. In addition, as especially shown in FIG. 4, each wire 11, 11...
In this case, two wires are placed close to each other as a set, and the distance between the four wires 11, 11 is wider than the distance between the two wires 11, 11 in the set.

By the way, the above arm mechanism has the following configuration. First, as shown in FIGS. 1 and 2, a bracket 13 is disposed above the engine 5 of the truck 1, and an arm 14 is pivoted to the bracket 13 at its lower end so that it can be raised and lowered. The bracket 13 connects the tip of the arm 14, which is arranged so as to be able to rise and fall freely, to the agitation control blade 6, which is directly above the container t and is in the state of being loaded into the container t.
The direction and position are determined so that it is located at the top of the liquid outflow direction. Further, a gear position 15 is provided at the tip of the arm 14. The gear device 15 is arranged so that the output shaft 16 hangs vertically into the container t when the arm 14 is in the down position.

Further, the rotational force transmission mechanism includes the gear device 15.

In the figure, reference numeral 17 indicates a stopper rod hanging from the lower part of the arm 14 so that the arm 14 stops descending at an appropriate position, reference numeral 18 indicates a handle piece protruding from the tip of the arm 14, and reference numeral 19 indicates a caster of the cart 1.

In this example, since the configuration is as described above,
It can be used as follows.

Here, an example will be shown in which a urethane-based two-component mixture, that is, a mixture of a main agent and a curing agent, is stirred and foamed. That is, the mixture is stirred and foamed during the reaction time of both agents, poured into the subfloor of a building, etc. in the foamed state, and the upper surface thereof is smoothed to form a resilient floor interior material.

First, the container t containing the above mixture is placed on the turntable 2. On the turntable 2, the outer periphery of the container t is held by a hoop 4.

After the container t is thus set on the turntable 2, the agitation control blade 6 is inserted into the container t at a predetermined position. That is, the agitation control blade 6 is lifted high, it is placed on the side of the container t, and the support pipe 7 fixed thereto is positioned above a predetermined corner of the cart 1, and then lowered. In this way, the stirring control blade 6 is inserted into the predetermined position of the container t, while the lower end of the support pipe 7 is fitted into the support cylinder 8 which is provided protruding from the corner of the cart 1. The stirring control blade 6, as shown in FIG.
In this manner, the outer end of the vertical plate portion 6-2 is in contact with the inner peripheral surface of the container t, and the lower end of the vertical plate portion 6-2 is in contact with the inner bottom surface of the container t, and is perpendicular to the rotation direction of the container t. is set to That is, the plate-shaped portion forming the stirring control blade 6 faces the center of the container t.

At the same time, the rotary foamer 9 is set in the container t.

First, the rotary foamer 9 is attached to the output shaft 16 of the gear device 15. This is done by fitting the collars 10, 10 onto the output shaft 16 and fixing them with screws.

Thereafter, the arm 14 is moved downward and the rotary foamer 9 is inserted into the container t. The arm 14 is stopped at a predetermined appropriate height by the action of the stopper rod 17.
Since the positional relationship of the arms 14 has been properly determined, the placement of the loaded rotary foamer 9 in the container t can be determined appropriately simply by the above-mentioned tilting operation.

After making these preparations, by driving the engine 5, the stirring operation and foaming operation of the mixture are reliably performed, and a large number of bubbles can be evenly dispersed in the mixture.

That is, when the engine 5 is driven to rotate, the turntable 2 rotates in a predetermined direction, which of course causes the container t held thereon to rotate in the same direction. In this way, the internal mixture starts rotating in the same direction and at substantially the same speed as the container t.

When the mixture starts to rotate in this manner, its flow is changed toward the center of the container t while being stirred by the stirring control blades 6 that intersect with the direction of rotation, and flows toward the rotary foamer 9.

As mentioned above, the rotational foamer 9 receives rotational force from the engine 5 through the pulleys p-3, p-5, p-6, p-4 and belts b-2, b-3, and is connected to the turntable 2. It is rotating in the same direction as , at about 10 times the speed. In this way, the rotary foamer 9 rotates and stirs the mixture flowing towards it, introduces air into it, forms fine bubbles, and evenly disperses the mixture in the mixture.

After the mixture reaches the required foaming state, the rotation of the engine 5 is stopped and the arm 14 is raised to take out the rotary foamer 9 from the container t, while the stirring control blade 9 is also pulled out from the container t. Fry.

In this way, the container t can be taken up from the turntable 2.

After that, the container t is transported to the designated floor base,
Pour the mixture and process as appropriate as above.

[Effects of the invention] According to the invention, it is possible to sufficiently stir a liquid that requires stirring and foaming in a short time, and at the same time generate an average foaming state.
