Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a needle punch m /
(c) a needle board maintenance cart for maintaining the needle board.

[0002]

2. Description of the Related Art Generally, in a needle punch m / c in which a nonwoven fabric or a knitted fabric is subjected to needle punching to impart entanglement to fibers, maintenance of the needle board, for example, manual needle replacement or needle replacement is performed. When performing maintenance such as cleaning, a table or a trolley on which the needle board is mounted has been used.

FIG. 8 is a cross-sectional view showing an example of a needle board. Many needles 20 are planted on the needle board 4.

In the above maintenance work, the maintenance work is performed by reversing the needle board in which the needles are planted. Conventionally, when performing this maintenance work, a person had to turn over a board with a needle attached.However, a board with a needle attached is heavy, and it is important to invert while holding this board. Work. In addition, the needle is planted up to the edge of the board, and the reversing operation is very dangerous, and there is a safety problem.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems, and to provide a needle board maintenance cart capable of improving safety and workability of needle maintenance work. It is in.

[0006]

According to a first aspect of the present invention, there is provided a needle board maintenance trolley having a support member for a needle board and a rotating member for rotatably supporting the support member for the needle board. It is a needle board maintenance cart characterized by the following.

Further, by holding the needle board only from the longitudinal side surface, there is no obstruction during needle maintenance. Further, it is characterized by having a mechanism capable of easily coping with a plurality of types of needle boards having different sizes. In addition, it is characterized by having a mechanism that can be easily inverted and fixed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail based on embodiments shown in the drawings.

FIG. 1 is a front view showing an embodiment of a needle board maintenance cart according to the present invention, FIG. 2 is a plan view of FIG. 1, FIG. 3 is a side view of FIG. FIG. 5 shows FIG.
FIG.

In FIG. 1, reference numeral 1 denotes a bogie frame which can be moved by wheels 10. Further, it can be fixed to the floor surface by the bogie stopper 11.

On both sides of the upper end of the bogie frame 1, there are provided rotary bearings 3 for supporting a board supporting frame 2 for supporting a needle board 4.

At one end of the board supporting frame 2 in the width direction, a board supporting guide 6 for supporting one width side of the needle board 4 in the longitudinal direction of the needle board 4 as shown in FIGS. Attached to the other end,
A board support guide 5 for supporting the other width side of the needle board 4 also in the longitudinal direction of the needle board 4
Are mounted via holders 13 which hold the board support guides 5 at both ends in the longitudinal direction. The board support guide 6 has a groove 6a corresponding to the thickness of the needle board 4.
And the board support guide 5 is a needle board 4
In addition to the groove 5a corresponding to the thickness of the groove 5, another groove 5b having a different depth is provided on the opposite side of the groove 5a.

That is, the needle board 4 is fitted along the grooves 5a and 6a of the board support guides 5 and 6,
Is held. The other board support guide 5 has a groove 5
a and 5b are rotatably supported so as to be located at the fitting positions of the needle board 4 described above. Therefore, as shown in FIGS. 4 and 5, the grooves 5a and 5b are appropriately selected corresponding to the needle boards having different widths.

FIG. 6 is an exploded view of the guide portion. As shown in FIG. 6, the board support guide 5 is fixed by fitting the groove stopper 9 provided on the holder 13 and the board support guide 5.

FIG. 7 is an enlarged view of the rotary handle. As shown in FIG. 7, the board supporting frame 2 can be rotated (reversed) by a rotating handle 7 attached to a board supporting frame shaft extending to the outside of the rotary bearing 3. Reference numeral 8 denotes a push-pull type rotation stopper of the board support frame.

In the present invention, since the work can be performed in almost the same state as when the needle maintenance work is carried on a table, the needle maintenance work is easy to perform. When reversing the needle board, the rotation fixing stopper 8 is removed while holding the handle on the rotating handle portion 7, and the handle 7 is rotated. 18
After rotating by 0 degrees, the position of the board is fixed in an inverted state by returning the stopper 8 to its original position.

Both ends of the board support guide 5 are cylindrical and are held by the holder 13 and are not rotated by the stopper 9 at the same time.

Therefore, the needle board is fixed in the reverse direction by the stopper 9, and the rotation shaft is received by the sliding bearing, so that the rotation and the fixing are easy.

The board supporting guide 5 is provided with a groove in accordance with the width and thickness of each needle board to be maintained. A stopper 9 for fixing the board supporting guide 5 is removed, and the board supporting guide 5 is rotated for maintenance. By fixing the stopper 9 in the groove portion corresponding to the needle board, it is possible to cope with several types of needle boards. In the case of this embodiment,
It can correspond to two types of needle boards. In this embodiment, the board support guide 6 is common to the two types of needle boards. However, when the size and thickness of the needle board are largely different, the same mechanism as that of the board support guide 5 can be used. Therefore, it is possible to easily cope with a plurality of types of needle boards having different sizes.

[0020]

As described above, the present invention can improve the safety and workability of the needle maintenance work in the needle board maintenance cart. Further, by having a mechanism capable of easily coping with a plurality of types of needle boards having different sizes, the workability of the needle maintenance work can be improved.
