Abstract

PURPOSE:To enable micro phase regulation of two machines, by pressing an idler roller of a belt type stepless speed change gear incorporated in a machine at the low speed side against a speed change belt to add the tension upon detection of phase shift. CONSTITUTION:When machine A is running with speed slightly lower than machine B, for example, the phase shift is detected by a phase detecting means 23 to provide a signal to a control means 19a of machine A. It will provide tension on a speed change belt through a roller 18a. Consequently the speed change belt will slightly enlarge a movable disc of an inverted speed change V-pulley against a pressing spring to displace the contact face with said V-pulley, to bring the rotary speed of said pulley slightly higher while machine A is operated with slightly high speed to eliminate the phase shift against machine B. Upon elimination of the phase shift, the roller 18a is reset.

Description

DETAILED DESCRIPTION OF THE INVENTION The present inventor has developed a multi-speed machine incorporating a belt-type continuously variable transmission having one pulley and a movable cone i attached to a fixed cone plate on the drive side and the driven side so as to be able to move toward and away from the fixed cone plate. This invention relates to a phase adjustment device for multiple machines that can automatically fine-tune phase shifts that occur during synchronized operation in an automatic synchronized proportional operation system that automatically synchronizes the operations.

When operating multiple machines with continuously variable transmissions in synchronization,
Even if an attempt is made to obtain a desired output rotation speed by adjusting the transmission output (b) rotation speed of each machine, it is extremely difficult to completely synchronize the operating speeds of a plurality of machines due to various scissor differences. For this reason, in order to perform synchronized operation of vIWI machines, conventional methods have been adopted such as detecting synchronization deviation between machines and controlling the speed of one motor to eliminate this synchronization deviation. In this case, the speed control is rough and cannot respond to minute speed fluctuations, which is inconvenient when highly accurate synchronized operation is required.In addition, when setting the initial operating speed of the machine, The machine had to be set to either high speed or low speed for all reference side machines, and it was difficult to say that it was a practically appropriate system.◎ This invention can be used as a continuously variable transmission to A belt-type continuously variable transmission with a variable-speed V-pulley on the driven side in which a movable conical plate is installed in opposition to a fixed conical plate so that the movable conical plate can be fully moved in and out of the machine. The rollers are fully built in to apply full tension to the speed change belt and finely adjust the rotational output, and a detection means that outputs a signal corresponding to the direction of phase shift between multiple machines is installed between both machines. ,
The control means for controlling the movement of the rollers are all connected to the detection means, and one of the machines is further provided with interlocking means for setting the output of the belt type continuously variable transmission in the speed increasing direction in conjunction with the movement of the rollers. This provides an extremely accurate multi-mechanical phasing system 6M.

This idea will be explained below based on the drawings. 11. - Figure 1 is a sectional view showing the basic transmission mechanism of a belt type continuously variable transmission, in which the drive side transmission V pulley (Vt)

It is mechanically connected to a control means such as a lever lowering, hydraulic or pneumatic cylinder, or pilot motor that supports the zero roller (I8) provided, and this control means (2) causes the spring (B) to It is configured to be moved clockwise (b) against the resistance, thereby pressing the speed change belt to apply tension and adjust the slow speed.

It is linked to the operation means ■.

are respectively connected to the control means (19b) on the four sides of the machine via a timer (to) or the like.A specific example of the detection means is not shown in the drawings, but both machine prisoners (If the sensor detects the direction of the phase shift and outputs a signal to the low-speed machine, it can be used as an optical sensor.
Any method such as mechanical or electrical means may be used.

The present invention has the above-mentioned configuration, and its operation will be explained below.

When operating the ll1Ir machines in synchronization, as shown in Fig. 3, the machine (4) is equipped with a detection means for detecting the direction of phase shift, and one of the output terminals (28&) of this detection means is attached. !Control means (19a) on the machine (4) side
), and the other output terminal ψsb) is connected to the machine (fourth side control means (19b)) via the timer flll. After this, the operating speed of the machine (6) is set to a desired speed by operating the operating means -. At the same time, the operating speed of the machine (4) is set to the first
The speed is set to be approximately the same as that of the machine (4) by moving the push rod (7) forward and backward as shown in the figure.

In this state, both machine prisoners start synchronized operation of (6).

At this time, when the machine side is slightly slower than the machine (B), the phase shift caused by this is detected by the detection means @, and the zero control means outputs a signal to the machine side control means (19a). (19a) I/i As shown in Figure 2, the adjustment lever (2) is moved clockwise around the spindle (B), so the roller (18a) on the adjustment lever)
suppresses the speed change belt o21' and applies tension to the speed change belt Q21. Therefore, the speed change belt (2)) slightly expands the movable conical plate α0 of the driven side speed change V pulley (v2) shown in FIG. Displace the contact surface with the As a result, the mechanical prisoner's output is the subordinate side variable train V-boo! J-(V
The rotational speed of 2) is slightly higher than when the roller (18a) does not act, and the mechanical prisoner is operated at a slightly higher speed in order to eliminate the phase shift with the machine (the seagull).

In this way, when the phase shift between the two mechanical causes (B) is eliminated, the input signal from the detection means to the control means α9a) disappears, and the operation of the control means 09a) stops, as shown in Figure 1. The adjustment lever (B) returns to its original position under the force of the spring (B), and along with this, the roller (18a) that was applying tension to the speed change belt (2) also returns to its original position. This allows the shift belt CI2+ and the driven side shift V-boo! J
- (The attachment position with 73ri returns to the initial state, and 1 machine (
The machine 5) continues to operate at a slightly lower speed than the machine 8, and thereafter the above-mentioned roller operation is repeated every time a phase shift occurs to maintain synchronized operation.

Also, when setting the operating speeds of machine (5) and machine (6), if machine (4) is slower than machine (6),
In Fig. 3, when the detection means detects the phase shift between the two machines (6), (6), the machine (Ba

That is, the lust is output to the control means (19b) via the timer. As a result, the roller (18b), which is activated for a certain period of time by the control means (19b), is moved in the first direction of the speed change belt, and further, in conjunction with the movement of the roller α8b), the operating means (2) is activated via the interlocking means @. It is set slightly to the speed increasing side. In this operation, the machine (B) is the machine (5)
is repeated until it is slightly faster than After the machine (Bl side) is set to a slightly higher speed than the machine (4), the control means (19m) on the machine (B) side operates in exactly the same way as described above when a phase shift occurs, and the phase shift is corrected. The synchronized operation between both machines is maintained.
.

All machines with relatively large load fluctuations are used during operation.
If it is set to the machine (b) side shown in the figure, more accurate synchronized operation can be performed.

As described above, according to the phase adjustment device of the present invention, when a phase shift is detected between a plurality of machines during synchronized operation, a belt-type continuously variable transmission is installed in the machine that has slowed down. By activating the control means and applying tension to the roller variable speed belt, it is possible to increase the speed until it is slightly faster than the other machine, making it possible to adjust the phase of either machine by a small amount. Not only can each machine quickly respond to even extremely small speed fluctuations, more accurate synchronized operation can be automatically performed, but also the operation speed setting operation can be simplified.
