[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to dispose a transport tool on a transport rail provided from a roving frame to a spinning frame so that the transport tool can travel, and to carry the roving bobbin by the transport device. Thus, the present invention relates to a roving bobbin transporting device configured to transport the roving bobbin from the roving frame to the spinning frame.

[0002]

2. Description of the Related Art Generally, a fully wound roving bobbin spun by a roving spinning machine is guided to a spinning machine by a roving bobbin conveying device as shown in FIG.

That is, the basic structure of the above-mentioned roving bobbin transporting device is provided with a hollow-shaped transporting rail (6) having a bottom opening from the roving frame (1) to the spinning frame (2). Four
Also, as shown in FIG. 5, the transfer tool (7) is movably arranged on the transfer rail (6), the transfer device (16) is attached, and the drive wheel (17) is provided on the transfer device (16). The transport tool (7) can be transferred by pressing against the (7).

Then, the roving bobbin (10) is constructed so as to be supported by the carrier (7), and the roving bobbin is operated by the operation of the transfer device (16).
Transfer rail (6) between roving frame (1) and spinning frame (2).
It is configured to be conveyed along.

In the above basic structure, a conventional roving bobbin transporting device is constructed as follows, as shown in Japanese Patent Publication No. 63-29016 (see FIGS. 4 and 5).

That is, a pair of carriages (21) are installed in the transport rail (6).
And the board (22) is attached to the pair of carriages (21) so as to be positioned below the transport rail (6). And the substrate
A plurality of bobbin holders (23) are hung on the lower surface of (22), and adjoining substrates (22) are connected by connecting links (24) to form a carrier (7).

The driving wheels (17) of the transfer device (16) are horizontally rotatably arranged on the left and right sides of the substrate (22) below the transfer rail (6).・ 25)
It is rotationally driven by a drive shaft (26) arranged along the transport rail (6) via a bevel gear (27). The substrate (22) is sandwiched from the left and right by the pair of rotating discs (25, 25) to transfer the carrier (7).

[0008]

In the above-mentioned prior art, the drive wheel (17) of the transfer device (16) is composed of a pair of rotating discs (25, 25) so that the substrate (22) is sandwiched from the left and right. Since it is configured, it is necessary to stretch the spring (28) between both rotating discs (25, 25) to keep the distance between both rotating discs (25, 25) constant, which is complicated. There is a problem that requires a different space holding mechanism.

Further, since the board (22) attached to the carriage (21) is long in the front-rear direction, the board (2) is not formed at the bent portion of the transport rail (6).
Both front and rear ends of 2) pass through the region bulging outward from the transport rail (6), while the central part of the substrate (22) is at the transport rail (6).
Will pass through the area inside. Therefore, as the radius of curvature at the bent portion is made smaller, the tip of the substrate (22) is more displaced from the transport rail (6), and unreasonable stress is applied to the connecting link (24). Has to be set relatively large, and there is a problem that a large space is required to dispose the transport device.

Further, since a part of the board (22) passes through a region outside the lower part of the carry rail (6) at the bent portion of the carry rail (6), the board (22) is sandwiched from the left and right. The transfer device (16) that must be installed must have
Since it greatly fluctuates from side to side with respect to (6), there is a problem that the transfer device (16) cannot be arranged at this bent portion.

SUMMARY OF THE INVENTION It is a technical object of the present invention to provide a roving bobbin transporting device which can simplify the structure of the transporting device and can be implemented at a low cost, and which can set a small radius of curvature at the bent portion of the transporting rail.

[0012]

According to the present invention, in the above basic structure, in order to achieve the above-mentioned object, a roving bobbin conveying device is constructed as follows.

That is, the carrier (7) is provided with a plurality of carriages (8 ...) Traveling inside the conveyor rail (6) and a bobbin holder (9) suspended on each carriage (8). (8) is the transport rail
The adjacent trucks (8) in (6) are connected to each other by the connecting link (11), and the upper surface of the truck (8a) and the upper surface of the connecting link (11a) are formed to be flat and substantially flush. The upper wall (6a) of the transfer rail (6) is provided with an opening (15), and the drive wheel (17) of the transfer device (16) is arranged above the opening (15) of the upper wall. A part of the driving wheel (17) is projected from the wall opening (15), and the upper surface (8a ・ 11) of the truck (8) and the connecting link (11) is driven by the driving wheel (17).
A protective cover (19) configured to press and press a) around the upper wall opening (15) of the transport rail (6) to cover the drive wheel (17) located on the transport rail (6). Is provided.

[0014]

In the transporting tool, since the upper surfaces of the carriages and the connecting links are formed to be substantially flush with each other, the transporting tool can be reliably transported by being pressed against one drive wheel from above.

Further, since the carriage is connected to the carriages adjacent to each other in the carriage by the connecting link, the carriage smoothly moves in the carriage even at a bent portion having a small radius of curvature. .

[0016]

The present invention has the following effects since it is constructed and operates as described above. (B) Since the drive wheels of each transfer device are configured to contact and press the dolly and the upper surface of the connecting link, the transport tool can be reliably transported by providing only one drive wheel, and it is possible to perform the transport as in the prior art. The structure is simple and can be implemented inexpensively without the need for a complicated space holding mechanism.

(B) Even at a bent portion with a small radius of curvature, the carriage travels smoothly inside the carrier rail, so that the radius of curvature of the carrier rail can be set smaller than in the prior art, and the equipment The layout area can be reduced.

(C) Since the drive wheels of the transfer device are configured to contact and press the upper surface of the carriage traveling inside the transfer rail, it should be arranged at any part of the transfer rail without being influenced by the bent shape. You can As a result, the arrangement interval of the transfer devices can be optimally set according to the length of the transport tool, and the minimum necessary transfer devices can be installed and can be implemented at low cost.

(D) Since the carrier comprises a plurality of carriages connected by connecting links, the number of roving bobbins to be conveyed can be freely set only by adjusting the number of connections. As a result, it is possible to apply to different models by adjusting the number of connections depending on the number of spindles of the spinning frame and the spinning frame.

(E) Since the bobbin holder is suspended from the bogie and the bogie is connected by the connecting link, the distance between the adjoining bobbin holders can be arbitrarily changed only by changing the length of the connecting link. can do. As a result, various spinning machines having different spindle pitches can be easily accommodated.
