JPS5943886B2 - Horizontal master controller - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a horizontal master controller, and more particularly to a horizontal master controller equipped with a circuit switch that interlocks with a key shaft orthogonal to a main camshaft.

An object of the present invention is to provide a horizontal main controller that can reliably switch related circuits at the same time as the main controller is unlocked.

According to the present invention, a circuit switching device is installed in a master controller and linked to a key shaft, so that circuit switching operations can be performed reliably.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

The figure shows an embodiment of the present invention, in which a main camshaft 2 includes a plurality of cams 2C and is held horizontally by a bearing body 1, and a main handle 14 connected to the main camshaft 2. Rotation operation is performed by moving up and down.

The main handle 14 extends toward the driver (downward in FIG. 1).

Note that correction of the torque of the main camshaft 2 is performed by a star wheel 4 whose detailed illustration is omitted.

A reversing shaft 7 is rotatably attached to the end of the main camshaft 2, and a reversing handle 8 extending toward the driver is connected and rotated, and the star wheel 6 determines the rotation position. ing.

In addition, the main camshaft 2 and the reverse rotation axis I are both star wheels 4 and 6.
At a specific rotational position, they are mutually locked by a locking mechanism 5 having a general locking configuration.

On the other hand, a notch 2G is formed on the outer periphery on the main camshaft 2 located between the star wheel 4 and the star wheel side bearing body 1.
A key shaft 9 is perpendicular to the date plate 2R and extends toward the driver in the same way as the main handle.

A large diameter portion 9B having an axial notch groove 9G is formed at a position of the key shaft 9 facing the disk 2R.

The notched groove 9G has a width that allows the disc 2R to be engaged with it.

A key guide 12 is provided at the extending end of the key shaft 9, and a key 11 is inserted into the key guide 12 so that the key shaft 9 can be rotated.

A cam 10 is provided on the key shaft 9 between the key guide 12 and the large diameter portion 9B, and a circuit switch 13 is arranged around the key shaft facing the cam 10.

What is now shown in FIGS. 1 and 2 is the notch groove 9 on the key shaft 9.
The disc 2R on the main camshaft 2 is engaged in the inside G, but since the disc 2B is not constrained in the circumferential direction, the main camshaft 2 can be moved freely by operating the main handle 14. Rotate to.

At the same time, the circuit switch 13B is activated by the cam IOB on the key shaft 9.
is closed, and the circuit switch 13A is open.

This state is maintained because the cutout groove 9G engages with the disc 2R and locks the rotation of the key shaft 9.

Next, when the main handle 14 is operated to rotate the main camshaft 2 to a specific position, the notch 2G of the disc 2R on the main camshaft faces the large diameter portion 9B on the key shaft 9. The state shown in Fig. 3 is reached.

In this state, the key shaft 9 can freely rotate, but since the key shaft 9 is still in the state shown in FIG. Since the large diameter portion 9B of the key shaft enters into the notch 2G, the two engage, and as a result, the main camshaft 2 is locked by the key shaft 9.

The rotation of the key shaft 9 causes the cam 10B to switch to the circuit switch 13B.
, the cam IOA closes the circuit switch 13A, and switches the circuit at the same time.

According to the embodiment of the present invention described above, since the key shaft 9 is installed in the same direction between the main handle 14 and the reversing handle 8, it is possible to easily operate the key 11, and the circuit The switch can be integrated into the main controller, and the key shaft that locks the main camshaft can also be used to operate the circuit switch, reducing the overall number of parts and simplifying handling. There is an effect that can be done.

According to the present invention, there are the following effects.

(1) Safety is assured because necessary circuit switching is reliably performed before train operation.

(2) Since the circuit switch is built into the main controller and operated by the key shaft, the operating mechanism and case unique to the circuit switch can be omitted, resulting in a large economic effect.
