Description

Detailed Description of the Invention

[0001]

[Field of Industrial Application] The present invention is to sample uncured concrete or mortar at a construction site, or to prepare a specimen having a shape and size specified by Japanese Industrial Standards from materials prepared in the same manner. The present invention relates to a formwork cleaner for a specimen used when doing.

[0002]

2. Description of the Related Art A conventional mold cleaner is one in which a mold is fixed, and a rotating brush that rotates at a constant speed is inserted into the inner surface of the mold while pouring water to remove dirt from the mold. was there. For example, see Japanese Utility Model Publication No. 3-20757.

[0003]

However, almost all of the above-mentioned cleaners are automated and have good workability, but on the other hand, the size of the device is large and the cost is high, and it is not convenient. However, even though it is an automatic device, there is a problem in that the inside and outside cannot be cleaned at once without removing the dirt on the outside of the formwork, which must be done manually. The present invention solves these problems at once by simple means.

[0004]

[Means for Solving the Problems] An inner surface cleaning means that rotatably supports a mold and inscribes the inside of the mold to wipe the inside of the mold, and an outside cleaning unit that contacts the form and cleans the outside. It comprises an outer surface cleaning means for wiping, and the inner and outer surface to be cleaned of the mold is interposed between both cleaning means so that the inner and outer surfaces of the mold can be cleaned simultaneously by rotating the mold.

[0005]

The mold is rotated together with the rotating brush by rotating the rotating brush of the inner surface cleaning means inscribed in the molding mold at an appropriate speed. In this state, the circumscribing brush of the outer surface cleaning means, which faces the rotating brush via the mold, is pressed against the outer surface of the mold to prevent the rotation of the mold by the circumscribing brush. There is a deviation in rotation between them, in which case the inner and outer surfaces of the form are wiped at the same time.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Explained in detail below with reference to the drawings, the outline thereof consists of an inner surface cleaning means A for wiping the inside of the mold and an outer surface cleaning means B for cleaning the outside of the mold.

First, the inner surface cleaning means A for wiping the inside of the mold a penetrates the floor surface of the machine base 1 and pivotally installs the shaft 2 of the rotating brush on the upper surface thereof, and the lower end of the shaft 2, that is, the machine. A pulley 15 which is linked to a drive source is fitted in the table 1, and a disk-shaped mold table 14 for mounting a mold a is fixedly mounted on the shaft 2 above the machine table 1. A part of the lower end of the form a or the entire end face is placed on the upper surface.

A large number of disc-shaped papers (or buffs, or resin-based sheet materials or the like may be laminated or sponge-shaped) may be provided upwardly above the mold table 14 of the shaft 2.
Are laminated to form a roll, and a rotary brush 3 having a sufficient length to reach the deepest inside of the mold of the longest size is formed.

Corresponding to the peripheral side of the rotating brush 3, the outer surface cleaning means B for wiping the outer side of the mold a is provided in parallel with the shaft 2 of the rotating brush 3 at a position offset to the upper surface of the machine base 1. 8 is erected, and a frame-shaped frame body 5 is pivotally mounted on the column 8 via an arm 9 protruding from one vertical side, and the upper side of the frame 5 and the column 8 are Spring 1 between top
The frame 5 is stabilized through the interposition of 1.

Between the upper and lower sides of the frame body 5, the central portions of the upper and lower sides of the brush frame 7 are pivotally attached by means of the pivots 4, and paper and other materials are attached to the two parallel vertical sides of the brush frame 7. Two rod-shaped circumscribing brushes 6, 6 are formed by winding or sandwiching (similar to the rotating brush 3), and the outer peripheral cylindrical surface of the mold a is wiped.

Further, one projecting piece 12 is horizontally projecting at a right angle at the center of the upper side of the frame body 5, and paper or other material (similar to the rotating brush 3) is provided at the lower edge of the projecting piece 12. The outer contact brush 13 for wiping the bottom surface (upper surface in FIG. 1) of the mold by sandwiching it or attaching it by other means. That is, by assembling, the projecting piece 12 operates integrally with the frame body 5 (the structure may be integrated from the beginning).

In the above structure, the frame body 5 slightly moves the brush 13 downward by utilizing the bending of the arm 9 and the play gap between the support column 8 and the arm 9 to move the upper surface of the form a. Although cleaning is performed, it is needless to say that this means is merely an example and is not limited to the above configuration, and may be any other means.

Further, in the inner surface cleaning means A, the inner brush for cleaning the inner surface of the mold a is the rotating brush 3. However, if only the mold a is rotated independently, the inner brush is the shaft 2. It is possible to make a fixed type brush independently from the above, and it is not necessary to stick to the rotating brush as shown in the figure, and the intended cleaning purpose can be achieved, which belongs to the category of the technical idea of the present invention. I will add that.

Next, a series of operations concerning the above mechanism will be explained. First, the already used and dirty mold a is laid down on the mold table 14 and supported by the rotary brush 3, and the shaft 2 is driven by the driving force acting on the pulley 15 (motor is not shown). Is rotated in a predetermined direction.

In this state, the mold a initially rotates together due to the contact friction between the table 14 and the rotary brush 3. Here, the frame 8 is held clockwise with the handle 8 with the column 8 as the axis. Move to (Fig. 3). Therefore, the two circumscribing brushes 6, 6 circumscribe two locations on the cylindrical surface of the form a.

Further, simultaneously with the above operation, by pushing the handle 10 downward (FIG. 2) against the elastic force of the spring 11, the projecting piece 12 also descends slightly according to the bending of the arm 9 and the play gap with the column 8, The edge circumscribing brush 13 presses the bottom surface of the mold a (FIG. 1) to clean the mold.

In this manner, the rod-shaped circumscribing brushes 6, 6 come into contact with the outer surface of the rotating mold a, thereby causing the mold 5 to move.
The rotation of the mold is delayed by the degree of holding of the handle, and the rotation is delayed. At that time, the inner surface of the mold 5 is rubbed by the rotating brush 3 to generate a cleaning action, while the mold a is circumscribed with the external brush 6 unless stopped. , 6 and the circumscribed brush 13 of the protruding piece 12
Be wiped by.

[0018]

According to the present invention, when the mold is rotated, it is sandwiched between the inscribed brush (rotating brush) of the inner surface cleaning means and the outer brush of the outer surface cleaning means. Both inside and outside can be cleaned at once.

Further, by changing the contact pressure of the circumscribing brush, the degree of adhesion between the circumscribing brush and the mold can be changed, the rotation of the mold can be controlled, and the cleaning action on the inner surface can be strengthened or loosened. is there.

Furthermore, the present invention has the unique effects of eliminating the complexity of conventional cleaners, of being easy to handle, and of being inexpensive.
