To provide a transport trolley which can be smoothly guided to a transport rail and can transport a roving bobbin along a spinning frame without any trouble.

<Background of the invention> Generally, the full roving bobbin spun by the roving frame 1 is transferred from the roving frame 1 to the spinning frame 2 by an overhead traveling type roving bobbin conveying device, as shown in Fig. 5. be guided.

That is, the basic structure of the above-mentioned roving bobbin conveying device for a spinning frame is as shown in FIG. A trolley 6 is provided in a movable manner within the loading rail 4, and the trolley 6
The transport trolley 7 is integrally suspended from the transport trolley 7, an operating handle 25 is attached to one end 26 of the lower surface 7a of the transport trolley 7, and the handle 25 for operation is attached to the center 2
A bobbin holder 8 is attached to the bobbin holder 8, and the bobbin holder 8 is configured to be able to support the roving bobbin 10, and the transport trolley 7 is transported along the carry-in rail 4 by manual operation of the operating handle 25, and the roving bobbin 1 is
0 to and from the spinning machine 2.

In this case, in particular, the roving bobbin 10 may be carried into the spinning frame 2 from the carry-in rail 3, or vice versa.
When transporting the product from the transport trolley 7 to the transport rail 3, the operator grasps the operating handle 25 disposed at the front end of the transport trolley 7 and operates it by pulling it forward so as to throw it away.

<Prior art> Examples of the prior art of the above-mentioned operating handle include:
As shown in Figures 4 and 5 of Japanese Utility Model Publication No. 57-4047 (see Figures 6A and B of the present invention), a bifurcated handle support part 50 is attached to the front end 26 of the transport trolley 7 in a downward direction. A smooth supported part 51 is formed on the upper part of the operating handle 25, the supported part 51 is pivoted around a support shaft 52 at the bifurcated part of the handle support part 50, and the support shaft 52 is conveyed. Transport direction A of trolley 7
There is one in which the operating handle 25 is swingable in a direction C perpendicular to the conveyance direction A with respect to the handle support part 50.

<Problem to be solved by the invention> However, in the above-mentioned conventional technology, the operating handle 25 swings only in the direction C perpendicular to the transport direction A, and does not move in the transport direction A, so to speak, relative to the transport trolley 7. Since the transport trolley 7 is fixed vertically in the spinning machine 2 by throwing out the operating handle 25 in the transport direction A, the operating force applied to the operating handle 25 will be applied to the transport trolley 7. 7, centering on the rear end of the handle 25.
This acts as a moment that pushes up the front end 26 to which the front end 26 is attached.

As a result, the transport trolley 7 along with the cart 6 is pushed forward toward the carry-in rail 4, and the cart 6 is pressed against the upper wall surface 4a of the carry-in rail 4, increasing frictional resistance. The manual operation of loading the spinning frame 2 into the spinning frame 2 and unloading it from the spinning machine 2 to the loading rail 3 does not go smoothly.

The technical problem of the present invention is to perform the above-mentioned manual operation on a spinning machine without any trouble.

<Means for Solving the Problems> Means for achieving the above problems will be described below with reference to drawings showing embodiments.

That is, in the present invention, in the roving bobbin conveying device for a spinning machine, the handle receiving part 28 is provided at the lower part of the conveying trolley 7, the handle receiving part 28 is formed into a protruding curved surface P that projects downward, and the protruding curved surface P is Trolley 7 conveying radius of curvature R
The operating handle 25 is oriented on a vertical plane B parallel to the conveyance direction A, and a long hole 29 is formed in the handle receiving portion 28 along the conveyance direction A, and the operation handle 25 is swung in the conveyance direction A into the long hole 29. A handle 25 for operation is movably penetrated through the
The present invention is characterized in that the lower surface 31 of the retaining portion 30 is configured to be able to come into contact with the convexly curved surface P of the handle receiving portion 28.

<Function> The handle receiving part 28 is formed into a predetermined convex curved surface P projecting downward, and the operating handle 25 is passed through the elongated hole 29 made in the handle receiving part 28 so as to be swingable in the conveying direction A, so that the operation can be easily performed. When the carrying handle 25 is thrown out in the carrying direction A and the carrying trolley 7 is conveyed within the spinning machine 2, the retaining part 30 of the operating handle 25 slides over the protruding curved surface P of the handle receiving part 28 into the elongated hole 29. The operation handle 25 swings along a vertical plane B parallel to the conveyance direction A, and the operating handle 25 slopes forward downward toward the conveyance direction A toward the bottom from the handle receiving portion 28 as a base point.

Therefore, as shown in FIG.
The operating force F applied to is a forward push force (more precisely, forward push component force F ₁ ) that acts in this forward downward tilting direction and acts as a moment to push up the transport trolley 7.
is reduced compared to the conventional technology, and conversely, a new downward pushing force F ₂ is applied, so that the transport trolley 7 along with the trolley 6 moves in front of the transport rail 4.
It will no longer be pushed in the direction of .

<Effects of the invention> (1) The operating force applied to the operating handle acts in this forward downward tilting direction, and while the forward pushing force is reduced compared to the conventional technology, a downward pushing force acts, which improves transportation. Since the trolley is smoothly guided along the carry-in rail, manual operations such as carrying the carrying trolley into the spinning machine and carrying it out from the spinning machine to the carrying rail become smooth.

(2) The operating handle can swing freely relative to the handle receiver, so even if a worker inadvertently touches the operating handle while the transport trolley is stopped inside the spinning machine, the operating handle will not be able to be operated. The handle swings backwards,
It does not act as a transport force for the transport trolley.

Therefore, if the transport trolley collides with another trolley, the roving bobbins hanging from the front and rear trolleys may collide with each other, or the impact of the trolley collision may cause the roving to protrude or collapse the shoulders. It is possible to prevent such defects from occurring, and in turn, it is possible to maintain good quality of the spun yarn.

(3) Since the handle receiving part is formed into a predetermined convex curved surface and the operating handle is swingably supported on the handle receiving part, the structure is simple, so it can be implemented at low cost.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

Fig. 1 is a partially cutaway side view of the area around the carry-in rail of a roving bobbin conveying device for a spinning machine, Fig. 2 is a side view of the main part of the operating handle, and Fig. 3 is a perspective view of the main part of the operating handle. FIG. 4 is a partially cutaway front view of an accompanying pusher type overhead running type roving bobbin conveying device, and FIG. 5 is a schematic overall plan view of the same roving bobbin conveying device.

As shown in FIG. 5, the overhead traveling type roving bobbin transport device has discharge rails 5 arranged along a plurality of rows of roving frames 1, and carry-in rails 4 arranged along a plurality of rows of spinning frames 2, and the discharge rails 5 are connected to the transport rails 3.
It is connected to the carry-in rail 4 via.

As shown in Fig. 4, each of the above rails 3, 4, 5
is formed of a rail member having a C-shaped cross section, and is arranged with its open groove 9 facing downward, and the full roving bobbin 10 spun by the roving frame 1 is transferred to the carry-out rail 5 →
The material is transported from the transport rail 3 to the carry-in rail 4 to the spinning machine 2 and spun.

That is, the conveyor rail 3 is configured in a closed loop so as to be able to reciprocate between the carry-out rail 5 and the carry-in rail 4, and a power chain conveyor 20 runs along the inner side of the carry-out rail 3 along its entire length in a closed loop. let

In addition, as shown in FIG. 1, a trolley 6 is movably accommodated within the transport rail 3, the carry-out rail 5, and the carry-in rail 4, and a plate-shaped transport trolley 7 is integrally suspended from the trolley 6. An operation handle 25 is attached to the front end 26 of the lower surface 7a of the trolley 7, a plurality of bobbin holders 8 are attached to the center 27 of the lower surface 7a of the transport trolley 7, and a roving bobbin 10 can be attached and detached to each bobbin holder 8. To support.

As shown in FIGS. 4 and 5, the drive motor 1
1, the power chain conveyor 20 is driven, and the pushing arm 12 extending from the power chain conveyor 20 pushes and moves the pusher 13 attached to the front part of the transport trolley 7 from the rear.
is configured to be transported along a transport rail 3.

The transport trolley 7 on which the plurality of roving bobbins 10 are suspended is then transported from the transport rail 5 along the roving frame 1 to the transport rail 3, and then automatically transported on the transport rail 3 by the power chain conveyor 20. , and is separated at the entrance of the carry-in rail 4.

Then, the transport trolley 7 separated from the power chain conveyor 20 is pulled forward by the operator by grasping the operating handle 25 of the transport trolley 7, and is carried forward onto the carrying-in rail 4 into the spinning machine 2. be driven along.

Therefore, the structure of the operating handle 25 will be described in detail as follows.

That is, as shown in FIGS. 1 to 3, a bent plate-shaped handle receiving portion 28 is attached to the lower surface 7a of the front end portion 26 of the transport trolley 7, and the handle receiving portion 28 is attached to a downwardly protruding curved surface P. Form.

In addition, as shown in FIG. 3, the operating handle 2
5 is formed into a long cylindrical rod shape, a long hole 29 is formed in the handle receiving portion 28 along the conveying direction A, and the operating handle 25 is passed through the long hole 29,
A retaining portion 30 is attached to the upper threaded portion 32 of the handle 25.
are screwed together, and the operating handle 25 is attached to the handle receiving part 28 so as to be swingable in the transport direction A.

The protruding curved surface P of the handle receiving portion 28 is a single curved surface whose radius of curvature R is oriented on a vertical plane B parallel to the transport direction A of the transport trolley 7 (i.e., the length direction of the transport trolley 7). The above-mentioned retaining portion 30
The lower surface 31 of is formed into the same single curved surface shape that can come into contact with the projecting curved surface P.

Therefore, the functions within the carry-in rail of the roving bobbin conveying device for a spinning machine will be described.

Due to the combination of the protruding curved surface P of the handle receiving part 28 and the lower surface 32 of the slip-off prevention part 30 of the operating handle 25 that comes into contact with this, the operating handle 25 is thrown out in the transport direction A, and the transport trolley 7 is moved into the spinning machine. 2, as shown by the solid line in FIG. The operation handle 25 swings, and the operating handle 25 slopes forward downward toward the conveying direction A as it goes lower from the handle receiving portion 28 as a base point.

Therefore, the operating force F applied to the operating handle 25 is
As shown in FIG. 2, while the forward pushing force F ₁ that acts in this forward downward slope direction and acts as a moment to push up the transport trolley 7 decreases, on the other hand,
Since the downward pushing force F ₂ is newly applied, the transport trolley 7 is moved to the carriage 6 as in the prior art mentioned above.
The entire front part will no longer be pushed up in the direction of the carry-in rail 4.

As a result, the transport trolley 7 is smoothly guided along the carry-in rail 4, so that the roving bobbin 10
Manual operations such as carrying the frame into the spinning frame 2 and carrying it out from the spinning frame 2 to the conveying rail 3 become smooth.

In addition, since the operating handle 25 is loosely fitted into the elongated hole 29 of the handle receiving part 28 so that it can be raised and lowered freely, the operator can use the operating handle when the transport trolley 7 is stopped in the spinning machine 2 Even if the handle 25 is inadvertently touched, the operating handle 25 will lift up from the handle receiving part 28, as shown by the imaginary line in section Q in FIG.
It does not act as a conveyance force for the conveyance trolley 7.

As a result, the transport trolley 7 collides with another trolley 7, and the roving bobbins 10, 10 suspended from the front and rear trolleys 7, 7 collide with each other, causing the roving to protrude and collapse the shoulders. It is possible to prevent such defects from occurring.

In addition, in the present invention, the protruding curved surface P of the handle receiving portion 28
is at least the radius of curvature R of the transport trolley 7
Since it is sufficient that the surface is oriented on a vertical plane B parallel to the conveyance direction A, it is not limited to a single curved surface as in the above embodiment, but may also be a multi-curved surface such as a spherical surface.

Further, for example, when the handle receiving part 28 is formed into a spherical surface, the lower surface 31 of the slip-off preventing part 30 of the operating handle 25 only needs to be able to come into contact with the handle receiving part 28. There is no problem in forming it.
