Abstract

PURPOSE:To facilitate the draw-up of a truck in a narrow space, by radiating electromagnetic waves of two types of frequencies different from the frequency of the main guideline on the road surface from branch lines and then detecting these electromagnetic waves by a sensor provided to a truck to control the driving wheels. CONSTITUTION:An electromagnetic wave of frequency f0 is radiated from a main line 20, and at the same time electromagnetic waves of frequecies f1 and f2 are radiated from branch lines 23 and 24 respectively. Direction control sensors 15 and 16 set on a truck 11 detect the electromagnetic wave of f0 and control driving wheels 12 and 13 so that the output winding is set at 0. When the truck 11 travels on the line 20 and gets close to branch lines 23 and 24, a constant position detecting sensor 18 catches an object 25 to be detected. At the same time, a controller 26 switches the receiving frequencies of the sensors 15 and 16 to f1 and f2 from f0. Then a controller 17 gives control with the outputs of sensors 15 and 16 so that the wheels 12 and 13 are set along the lines 23 and 24. As a result, a truck 10 can be easily put close to a working truck 19 even in a small space.

[Based on the detection operation during width-shifting of &, the sensing frequency of each of the steering sensors (one horse is switched to the same wave number (f,), (f,) for each branch line +73, L241. 1) Electromagnetic induction In the method, main line (a) and branch line prisoners, (
The cable is a Tokubus wire and emits electromagnetic waves by itself. In the optical i-shu 4 force type, the zero line ■ and the support 1m +xl,
+U is a light-reflecting tape that reflects light (electromagnetic waves in a certain wavelength range) from the light projector of the truck (11). The effect of the composition of the above seal or picture is as follows. See Figure 4. (The bogie U1+ travels along the main line (4) while being guided by the frequency (fo), and the fixed position detection sensor (181) captures the detected object (a) on the road surface. This causes the control device (support) to operate. The direction sensor (151, (!e+) automatically switches the sensed frequency from (f.) to (f,), (f,). Then, based on the detection signal from sensor a51. !
ll1ilf13, ua+ is a sensor that rotates integrally with this (1 (g), +161 is an example of a branch line, (2)
The steering control is performed to follow the direction. The effects of the present invention are as follows. [Pi] The branch line can be short. (0) The required road surface space is smaller due to the width adjustment C. (c) Less time is required for width adjustment. ) Width alignment can be performed reliably. In particular, it is possible to perform width adjustment in close contact with the side edges of the work area. Next, embodiments of the present invention will be outlined. (1) 2 for each steering sensor (19/n (16))
Each one of the two sensitive frequencies is equal to each other (f. ), and the remaining frequencies (f, ), (f, ) are also equal to each other (f; = f, ). In this case, two supports 4A+
It is advantageous to use the same oscillation source for 'n and (to) and to make the two steering sensors t151 and 1161 the same. (2) This is shown in Figures 8 and 4, and the fixed position detection sensor (110 is a combination of a pair of front and rear reed switches (2n, (support)), The magnet field consists of the combination of (1). This means that the frequency f0 → f, (or f1 → f.) and the wave number f0 → f, ('l: f, → f, )
This allows the timing of the switching to be shifted. In other words, this is to appropriately deal with the problem that occurs when the drive wheels (121, il:l) are steered separately, which requires shifting the timing of frequency switching.Next, The embodiment will be explained based on Figs. 5 to 7. Fig. 5 shows the truck (Ill). 31) (to) is a caster and is on the diagonal line of the truck + Ill. Drive wheel shi, 0

i is the driving motor that drives each drive wheel +12), +13, (2) is the steering motor of each drive wheel t121, (131), and the sprocket country of each drive wheel (12), +13), c@ Transmitted by chain (39), +401. (4υ is a guide roller with a vertical shaft attached to the side edge of the truck OIl, which acts on the side edge (421) of the work location (191). All guide rollers (41) act on the side edge (421). In the width-aligned state, each -t= =z ? +151

Frequencies (f,) and (f,) from +24) of the branch line
In the width-closing state where the electromagnetic waves are captured, a (b. In other words, the electromagnetic energy captured by the pickup coil (4) is larger than the electromagnetic energy captured by the pickup coil (441). A steering force is applied to move it in the direction of the arrow. In other words, width closing is performed to #1. When escaping, the frequency (fρ, (f
, ) and escape while catching the electromagnetic waves of each reed switch (2
), (When 28+ captures magnet (2), CI, the main line (
A) The sensing frequency of the coil (C), 1441 is changed to f1→f, , f, →f as guided by the coil (C). You may also switch to However, if you switch from the beginning of escape, you will get the following advantages. That is, a/) b/, so the trolley +II
) tries to move in the direction of arrow ■] from the initial stage of escape, and the guide roller (4υ) is immediately separated from the side edge (42).
In other words, there is no escape resistance due to the rubbing of the guide rollers, allowing for smooth escape. In Fig. 8, a light emitter (for example, a light receiver), (4η is a light reflecting surface. , (to).An alternative to this is the fixed position stopping method.
