Reference numeral 11 denotes a pulley attached to the drive wheel 10, reference numeral 12 denotes a drive motor such as an inverter motor mounted on the work vehicle V, which can be rotated forward and backward, and the drive motor 12 has a built-in braking device. Have been. Reference numeral 13 denotes a pulley attached to the output shaft of the drive motor 12, and a pulley 11 attached to the drive wheel 10.
And pulley 13 attached to the output shaft of drive motor 12
, An endless belt 14 such as a timing belt is stretched.

Reference numeral 15 denotes drive wheels mounted on a rail 8 installed on the floor, which is provided near the other end of the work vehicle V in the traveling direction. Reference numeral 16 denotes a pulley attached to the drive wheel 15, and reference numerals 17, 18, and 19 denote tension pulleys provided in the middle of the pulleys 11 and 16. A pulley (not shown), which is attached to the drive wheel 10 and is also juxtaposed to the pulley 11 attached to the drive wheel 10, and a pulley 16 which is attached to the drive wheel 15
An endless belt 20 such as a timing belt is stretched between the tension pulleys 17, 18, and 19.

By appropriately driving the drive motor 12 in the forward and reverse directions, a drive disposed near one end of the work vehicle V in the traveling direction via the pulley 13, the endless belt 14, and the pulley 11 is provided. The work vehicle V is driven by driving the wheel 10 and via a pulley (not shown) attached to the drive wheel 10, tension pulleys 17, 18, 19, an endless belt 20 and a pulley 16 attached to the drive wheel 15. The driving wheels 15 arranged near the other end in the traveling direction are driven.

21a and 21b are guide wheels arranged on the work vehicle V so as to sandwich the upper rail 9 installed on the spinning machine S, and 22a and 22b are guide wheels 21a and 21b.
This is a similar guide wheel disposed at a position separated by a predetermined distance from 21b.

As described above, the rail 8 installed on the floor
Since both wheels mounted on the vehicle are configured as the drive wheels 10 and 15, the work vehicle V can be started or run without causing a slip between the rail 8 and the drive wheels 10 and 15. The vehicle can be accelerated to a steady state traveling speed in a short time, and a stable traveling state can be realized.

Further, since both wheels mounted on the rail 8 installed on the floor are configured as drive wheels 10 and 15, the rail 8 and the drive wheels 10 are used even when the work vehicle V is driven at high speed. , 15 can be operated at a high speed in a stable state.

Without using multiple drive motors,
By one drive motor 12, a plurality of drive wheels 10,
Since the drive vehicle 15 is configured to be driven, the weight of the work vehicle V is not increased, so that energy saving can be realized and the cost of the work vehicle V can be reduced.

Since both wheels mounted on the rail 8 installed on the floor are formed as drive wheels 10 and 15, the spinning unit s is always provided regardless of the traveling direction of the work vehicle V.
In contrast, the work vehicle V can be stopped at a fixed position, so that the success rate of the doffing operation, the piecing operation, and the like can be improved, and the operation of adjusting the stop position can be omitted.

When the work vehicle V is equipped with both a piecing device and a doffing device, the work vehicle V is equipped with either a piecing device or a doffing device. In comparison, since the work frequency increases, the starting speed and the steady speed of the work vehicle V need to be increased. However, in the present invention, the start speed and the steady speed of the work vehicle V can be increased by the above-described configuration. Since it can be realized, the work cart V can be quickly and accurately moved to the spinning unit s where the splicing operation or the doffing operation is required, and therefore, the spinning efficiency of the spinning machine can be increased. it can.

The production speed (spun speed) of the spun yarn Y is 35
In the case of a high-speed spinning machine of 0 to 400 m / min, in order to take advantage of the high-speed spinning machine, at high speed and accurately, up to the spinning unit s where splicing work or doffing work is required. Although it is necessary to move and stop the work cart V, both the wheels mounted on the rail 8 installed on the floor are configured as drive wheels 10 and 15, so that the piecing operation or doffing is performed. Up to the spinning unit s where work is required, the work vehicle V
Can be moved.

In the above-described embodiment, an example is shown in which one rail is installed on the floor and two drive wheels are used. However, two rails are installed on the floor, and Four drive wheels may be mounted on the rail.

[0022]

Since the present invention has the above-described structure, the following effects can be obtained.

The work vehicle can be started or run without causing a slip between the rails installed on the floor and the drive wheels, so that the work speed can be accelerated to a steady state running speed in a short time and stable. A running state can be realized.

Even when the work vehicle travels at high speed, no slip occurs between the rails mounted on the floor and the drive wheels, so that the work vehicle can travel at high speed in a stable state.

Without using multiple drive motors,
Since a plurality of drive wheels are driven by one drive motor, the weight of the work vehicle is not increased, so that energy saving can be realized and the cost of the work vehicle can be reduced.

Since the wheels mounted on the rails installed on the floor are configured as drive wheels, the work cart can always be stopped at a fixed position with respect to the spinning unit regardless of the traveling direction of the work cart. Therefore, the success rate of the doffing operation, the piecing operation, and the like can be improved, and the operation of adjusting the stop position can be omitted.

Since the starting speed and the steady speed of the work vehicle equipped with the piecing device and the doffing device can be increased, the spinning unit which requires the piecing operation or the doffing operation can be quickly operated. In addition, the work cart can be accurately moved, and therefore, the spinning efficiency of the spinning machine can be increased.
