Description

  The present invention relates to a polishing apparatus that removes and polishes rust, dirt, adhered and solidified concrete, paint, and the like on long members such as reinforcing bars, scaffolding pipes, water pipes, and steel shapes.

Conventionally, rust, dirt, etc. of long members such as reinforcing bars, scaffolding pipes, water pipes and steel molds (hereinafter simply referred to as long members) are removed by attaching a cup brush to a baby sander etc. Or removing it while rubbing it with a hand holding a gold brush.
However, these removal methods not only have a heavy burden on the human body, particularly a burden on the hands and arms, but also have a problem that it takes a long time to remove rust and dirt and the work efficiency is poor.

Therefore, conventionally, as a solution to such a problem, the brush holding member is rotated in a container which is composed of two divided members, which can be opened and closed, and through which a long and narrow object passes. A cleaning device (see Patent Document 1) provided with a brush supported in a possible manner, and a cylindrical brush (see Patent Document 2) in which a brush is provided on the inner side (inner surface) of a spiral cylindrical shape or a C-shaped cylindrical shape. Is provided.
JP 11-114514 A JP 2003-70545 A

With the two members open, the cleaning device arranges an elongated object along the through-hole and closes the dividing member, and moves the cleaning device along the elongated object, or fixes the cleaning device to fix the elongated object. When the is moved, the brush rotates in contact with the elongated object and cleans the surface of the object, which is a preferable device depending on the object to be used.
However, this is suitable for cleaning dirt and debris on the surface of an elongated object because the brush rotates by contact friction with the elongated object. It cannot be applied, and there is a problem that it is not suitable to be applied to a heavy long member such as a reinforcing bar, a metal pipe, and a steel plate to which the present invention is applied.
In addition, the cylindrical brush is rotated by hand or moved up and down to clean the attached dirt, so that a burden is placed on the hand and work efficiency is poor.

  This device was proposed to solve such problems, and its purpose is to greatly reduce the burden on workers, especially the burden on hands and arms, shorten the work time and improve the work efficiency. An object of the present invention is to provide a polishing apparatus that removes and polishes the rust and dirt of the long member to be improved and the adhered and solidified concrete.

In order to achieve the above-mentioned object, the long member blasting apparatus of the present invention is provided on a machine base so that a rotary brush connected to a motor and rotating can be opposed and advanced.
Located on an extension line that crosses the intermediate position of the opposed rotary brush, a support member for supporting the long member is provided,
It is characterized in that the long member supported on the support member is moved to clean the surface with a rotary brush.

  With this configuration, the support member is provided on an extended line that crosses the intermediate position of the opposing rotary brush. Therefore, when the long member is supported by the support member and set, the long member is located between the opposing rotary brushes. Located in. Opposing rotary brushes can move forward and backward (can be moved away from each other), so when long members are set, they are set to move backward (separate) from each other, and at the time of cleaning, they are moved forward to reduce the interval. It can be brought into contact with the scale member. Accordingly, the long member that is separated from the rotary brush and supported by the support member is positioned in the middle of the opposing rotary brush. Contact the set long member. Therefore, rust, dirt, adhered and solidified concrete, paint, etc. on the surface of the long member are removed and cleaned by a rotary brush rotated by a motor. At this time, since the long member is supported by the support member and moved, the burden on the operator is reduced and the work efficiency is improved. In particular, if the long member is automatically moved by the moving means that is driven by the drive source, the burden on the operator is further reduced, and the work efficiency is further improved.

Further, the rotary brush that is connected to the motor of the long member polishing apparatus of the present invention and rotates is screwed into a screw shaft provided on the machine base, and confronts by rotating the screw shaft forward and backward. It is provided on the strut member that advances and retreats, and is capable of advancing and retreating (contacting and separating) facing each other by the strut member that advances and retreats in opposition.
With this configuration, the opposing rotary brushes can be moved back and forth (contact and separation) by rotating the screw shaft in the forward and reverse directions with a handle or a motor.

In addition, the rotary brush that is connected to the motor of the long member polishing apparatus of the present invention and the support member that supports the long member are covered in a case having an insertion port through which the long member is inserted. It is characterized by being.
With this configuration, it is possible to prevent rust, dirt, adhered and solidified concrete, paint and dust, etc. removed from the long member during the blasting work from being scattered outside, thereby protecting workers and neighbors. , Environmental pollution can also be prevented.

Further, the case of the long member polishing apparatus of the present invention is characterized in that an upper part is opened and a lid is provided in the opening so as to be openable and closable.
Since the upper opening of the case can be opened and closed by this configuration, the rotary brush replacement work, the support member replacement work and the maintenance work can be easily performed.

Also, under the rotating brush connected to the motor of the long member blasting apparatus of the present invention and rotating, the removed material that has been removed by polishing the long member with the rotating brush is collected and guided. A chute is provided.
With this configuration, the removed material that has been removed by scouring the surface of the long member with a rotary brush can be collected without being scattered and stored in a container, bag, or the like for disposal. This prevents environmental pollution and does not cause pollution problems.

Further, the support member of the long member polishing apparatus of the present invention is detachably provided on the machine base, and can be replaced corresponding to the long member.
With this configuration, the support member can be easily replaced, so that the long support member can be replaced with an optimal support member. For example, there are large differences in diameter, shape, and weight when the long member is a reinforcing bar and shape steel, but the same support member is not easy to use and the workability is reduced, but by replacing it with a suitable support member, Such a problem can be solved.

According to the long member polishing apparatus of the present invention, the following effects are obtained.

  Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view showing a long member scouring apparatus according to an embodiment of the present invention. FIG. 2 is a perspective view of a long member scouring apparatus according to an embodiment of the present invention in an open state. FIG. 3 is an exploded perspective view showing the main part of the long member blasting apparatus according to the embodiment of the present invention, and FIG. 4 is a sectional view of the long member scouring apparatus according to the embodiment of the present invention. FIG. 5 is a cross-sectional view of a long member blasting apparatus according to an embodiment of the present invention.

  The long member polishing apparatus is provided on a machine base 1 with rotary brushes 2a and 2b that are connected to a motor 3 and rotate so as to be opposed to each other. Positioned on an extension line that crosses the position, there are provided support members 4 and 4 for supporting the long member T, and the surface of the long member T supported by the support members 4 and 4 is moved (forward / reverse and rotation) Is cleaned by the rotary brushes 2a and 2b.

  As shown in FIGS. 1 and 2, the machine base 1 is provided with support legs 5 and supported at a predetermined height. Accordingly, the height of the long member T can be set so that the operator can easily stand up. On the machine base 1, two support members 6a and 6b are provided facing each other, and the rotary brushes 2a and 2b and the motor 3 are provided on the support members 6a and 6b. The rotary brushes 2a and 2b are connected to a motor 3 fixed to the column members 6a and 6b and are driven to rotate.

  As shown in FIGS. 4 and 5, the machine base 1 is provided with a screw shaft 7 rotatably supported by a bearing member 11. In this example, a handle 8 is provided at one end of the screw shaft 7. It can be rotated. The screw winding direction of the screw shaft 7 is opposite to the one side 7a and the other side 7b from the middle as shown in FIG. Movers 9a and 9b are screwed into portions 7a and 7b of the screw shaft 7. Accordingly, when the screw shaft 7 is rotated in the forward and reverse directions, the movers 9a and 9b move, but the movers 9a and 9b move in opposite directions, that is, for example, the screw shaft 7 rotates in the forward direction. In movement, the movers 9a and 9b move toward (forward) each other, and move away (retreat) from each other in rotation in the reverse direction. Movement tables 10a and 10b are fixed to the movers 9a and 9b. Therefore, the movement tables 10a and 10b also move together with the mover. The column members 6a and 6b are fixedly erected on the moving tables 10a and 10b. Accordingly, the support members 6a and 6b also move together with the mover. Further, the support members 6a and 6b are provided with rotary brushes 2a and 2b that are connected to the motor 3 and rotate to face each other. The brushes 2a and 2b face each other and move away from each other. The screw shaft 7 may be rotated by a motor.

The rotary brushes 2a and 2b are provided so that the front faces are opposed to each other over the entire surface, and when the long brushes approach each other, the elongate member T comes into contact with the shape substantially across the center of the rotary brushes 2a and 2b. As shown in the drawings, they may be provided so as to face each other at an angle, and the long member T may be rotated in contact with the vicinity of the outer periphery of the rotary brushes 2a and 2b. Such setting is arbitrary.
If the rotary brushes 2a and 2b are detachably attached to the rotary shaft 13 connected to the motor 3 via a transmission mechanism as shown in FIG. 3, the rotary brushes 2a and 2b are replaced when worn or when the long member is removed. This is preferable. In this example, as shown in FIG. 3, the rotary shaft 13 can be attached and detached with a nut 14.

The support member 4 is provided on an extension line crossing an intermediate position between the opposed rotary brushes 2a and 2b. In this example, two pieces are provided at the front and rear. The support member 4 is detachably attached to a support member 12 erected on the machine base 1. In this example, as shown in FIG. 3, the support member 12 is constituted by a hollow member, and the support member 4 is inserted into and attached to the hollow portion of the support member 12 and is detachable.
Since the support member 4 is used for carrying out the cleaning work by placing the long member T on the support member 4, the support member 4 is composed of a U-shaped support part 4a. It can be placed and set here. Since the long member T that cleans the surface has various diameters and shapes such as a reinforcing bar, a pipe for scaffolding, a water pipe and a steel plate, the bearing member 4 is intended for the bearing portion 4a. Prepare a shape suitable for each long member T. As a result, the long member T can be used by replacing it with the optimum support member 4. In FIG. 3, three types of support members 4 are illustrated.

In addition, the rotary brushes 2a and 2b that are connected to the motor 3 and the support member 4 that supports the long member T are surrounded (covered) by a case 15 having an insertion port 17 through which the long member T is inserted. ) The case 15 is installed on the machine base 1.
This case 15 prevents rust, dirt, adhered and solidified concrete, paint, dust, and the like removed from the long member during the polishing operation from being scattered outside. Even if surrounded by the case 15, the insertion member 17 is provided, so that the long member T can be inserted through the insertion port 17 to perform the polishing operation.
As shown in FIGS. 1 and 2, the case 15 has an opening 15a on the upper side. When the lid 16 is provided in the opening 15a so as to be openable and closable, the lid 16 is opened to open the rotary brushes 2a and 2b. The replacement work, the replacement work of the support member 4 and the maintenance work can be performed, which is preferable. Of course, the lid 16 is sealed during the cleaning operation. In this example, the insertion port 17 is provided in the lid body 16, but this is appropriate. For example, when a semicircular notch is provided in a part of the periphery of the opening 15a of the case 15, and a semicircular notch is provided in a part of the periphery of the lid 16 corresponding to the notch, and the lid 16 is closed. You may make it form an insertion port by both notches. According to this configuration, there is an advantage that the long member T can be inserted and set from the insertion port 17 with the lid 16 closed, and can be set with the lid open. Therefore, it is preferable for the setting of the long member T which has a weight like a steel plate and is difficult to be set through the insertion port 17. In other words, the lid 16 can be closed and set after the lid 16 is opened and the long member T is placed on the support members 4 and 4.
Further, it is preferable that at least the lid 16 of the case 15 is made of a transparent or translucent plastic member because the state of polishing can be visually confirmed during the operation.
In this example, the rotary brushes 2a and 2b and the support member 4 are also surrounded by the case 15. However, the case 15 prevents the removal and dust from being scattered during the cleaning operation. Since the removed matter and dust are generated from the rotary brushes 2a and 2b, the case 15 only needs to surround at least the rotary brushes 2a and 2b.

Further, below the rotary brushes 2a and 2b that are connected to the motor 3 and rotate, a chute is provided on the machine base 1 and contracts downward in a conical shape as shown in FIGS. 18 is provided, and the lower end of the chute 18 is a discharge port 19.
As a result, the removed material removed by polishing the surface of the long member T with the rotary brushes 2a and 2b can be collected in the chute 18 and guided to the discharge port 19, and a container or bag ( By installing (not shown), it can be collected and accommodated. Accordingly, the removed matter that has been removed by polishing the surface of the long member T with the rotary brushes 2a and 2b can be collected and disposed of without being scattered. Moreover, since it does not scatter around, it is hygienic and can prevent environmental pollution.

  Thus, according to the long member blasting apparatus of this embodiment, first, the rotating brushes 2a and 2b facing each other by rotating the screw shaft 7 with the handle 8 are moved backward and separated from each other. The scale member T is inserted from the insertion port 17 and placed on the support members 4 and 4 and set. Therefore, when the screw shaft 7 is rotated in the reverse direction by the handle 8, the opposing rotary brushes 2a and 2b come into contact with the long member T set in close proximity. Therefore, when the rotary brushes 2a and 2b are stopped and the rotary brushes 2a and 2b are rotated by the motor 3, rust, dirt, adhered and solidified concrete and paint on the surface of the long member T are removed and polished. Therefore, when the long member T is sequentially rotated while moving forward (there may be retracted when there is a removal residue), the entire surface of the long member T has rust, dirt, adhered and solidified concrete and Paint, etc. are removed. Hereinafter, the same operation may be repeated for each long member T. .

At this time, as shown in FIG. 1, even if the operator holds the elongate member T in his / her hand and rotates and moves forward / backward, the elongate member T is supported by the support member 4. The burden on the arm and arm can be greatly reduced and the work can be done easily.
The long member T may be rotated or moved forward / backward by a rotating / moving means driven by a motor or the like instead of the worker. In this case, the burden on the worker is further reduced.
As the rotating / moving means, a moving element (sliding member) is provided on the rail so as to be movable back and forth, and a chuck provided on a spindle connected to the motor is mounted on the moving element, and a long member is held by the chuck. A configuration in which the long member is rotated by rotating the spindle with a motor and the long member is moved forward and backward by moving the moving member can be exemplified. At this time, the mover can be moved by expanding and contracting the cylinder or rotating the suspended chain.
In this embodiment, the driving / stopping and forward / backward movement of the rotary brushes 2a and 2b can be operated with a foot according to the petal switch 20 as shown in FIG. It is desirable that it can be operated even if T is held in hand.

  The above embodiment does not limit the present invention, and various modifications are allowed without departing from the spirit of the present invention.

  This device is applicable not only to remove reinforcing bars, scaffolding pipes, water pipes and steel molds, but also to remove objects such as rust and dirt on the surface of other long members.
