Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a carrier truck that travels along a predetermined track rail to carry articles and the like, and more particularly to a carrier device using a linear induction motor as a drive source.

"Prior art" As is well known, many transport systems are used in a factory assembly line, warehouse equipment, etc., in which a plurality of transport carriages can be systematically operated in accordance with control commands, etc. on prescribed rails. .

FIG. 4 and FIG. 5 are a cross-sectional view and a side view of a carrier truck having a linear induction motor as a drive source used in such a carrier system. In the figure, reference numeral 1 denotes a rectangular parallelepiped body on which a conveyed object such as a work is mounted.
Reference numeral 2 is a wheel, 3 is a track rail laid on the ground, and 4 is a primary side coil of a linear induction motor, which is mounted on the rail 3 side at an appropriate height. Reference numeral 5 denotes a secondary side conductor of the induction motor, which is provided on the vehicle body 1 side and constitutes a linear induction motor together with the primary side coil 4. 6 and 6'are sensors for detecting the position of the bogie when the bogie is stopped, and a proximity switch is adopted,
It is mounted on brackets 7 and 7'fixed to the track rail 3 side. Reference numeral 8 denotes a carriage position detecting sensor for accurately stopping the carriage at a predetermined stop position, which is attached to a side surface of a bracket 9 fixed to the track rail 3 side, and is mounted on a side surface central portion of the vehicle body 1 side. By detecting the plate 10, a position detection signal for stopping the carriage at an accurate stop position is sent to the control unit. 11 and 11 'are sensors for detecting the speed of the trolley, which are arranged on the brackets 12 and 12' fixed to the track rail 3 side. An optovaver sensor is used and a slit plate provided on the vehicle body 1 side. The traveling speed of the trolley is detected by interrupting the light by the action of slits arranged in a large number in 13. The slit plate 13 also serves as a sensitive plate for the sensors 6 and 6 '.

By exciting the primary side coil 4 in such a structure, the vehicle body 1 receives thrust, and the truck travels along the track rail 3. And its running speed is sensor 11, 11 '
Detected based on this detection, control is performed based on this detection,
Further, the bogie is braked according to the speed at that time based on the detection of the vehicle body position by the sensors 6 and 6 ', and the movement of the bogie is finely controlled based on the accurate position detection of the bogie by the sensor 8. Is accurately stopped at a predetermined stop position.

[Problems to be solved by the invention] By the way, the above-mentioned conventional trolley has a large number of sensors, and all of these sensors are independently mounted on the bracket attached to the track rail 3. It is necessary to maintain the relative position of each sensor accurately.Therefore, when the brackets that hold each sensor are independently mounted on the rails, etc., the relative position between each sensor, and therefore between each bracket. Since it is necessary to adjust the relative position of and the number of parts is large, the assembly work takes time, and at the same time, the manufacturing man-hours and parts management are troublesome.

"Means for Solving Problems" In order to solve the above-mentioned problems, this invention integrates each bracket that supports each sensor with a continuous plate, and mounts each sensor on the bracket of this integration type. It is installed and the integrated bracket is attached to the track rail.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of a dolly in which the present invention is implemented,
FIG. 2 is a side view, and FIG. 3 is a perspective view of a bracket, in which 1 is a vehicle body, 2 is wheels, 3 is a track rail, and 6 and 6'are trucks for stopping the truck at a fixed position. Sensors for position detection, 11, 11 'are sensors for speed detection,
Reference numeral 13 is a speed detecting slit plate.

The structure of each of the above parts is not different from the conventional one shown in FIGS. 4 and 5, but in the present invention, it is for supporting the sensors 6, 6 ', 11, 11', etc. A mounting piece 14a for mounting the sensor bracket 14 on a track rail 3 part, which is formed by press working from a plate member punched into a predetermined shape with a continuous integral shape, a speed flush with this part The sensor mounting portion 14b for detection, and the sensor mounting portions 14c, 14d for fixed position vehicle stop symmetrically formed by bending at both ends to a predetermined height, respectively, the mounting hole 1 provided in the mounting portion 14a
It is fixed to the track rail 3 using 4e, speed detection sensors 11 and 11 'are attached to 14b, and 14c and 14d.
Sensor 6 to stop the truck at a fixed position
6'is attached respectively.

 The embodiment of this invention is constructed as described above.

"Effect of device" As described above, the device of the present invention has a continuous, integral bracket for installing a sensor for detecting the speed of the carriage and the position of the carriage for stopping the carriage. The sensor is attached to this as a common bracket for these, and the mounting position between each sensor is precisely machined to a fixed size, so that the relative position between each sensor is kept constant, Position adjustment between each sensor is not necessary, and the number of parts is one, so that it is possible to reduce the number of manufacturing steps and the time for assembling work.
