Abstract

PURPOSE:To precisely feed oil even if a chain link moves at high speed by counting the frequency of passing of pins to discharge oil one time on every total number in a system oil is fed to a pin of a chain link from a pump. CONSTITUTION:The passing of pins of a chain link 9 is detected by a near-by switch 8 and the detection signal is input to a counter 17. When the accumulation number reaches a certain set number in relation of a prime number to the number of links of the chain link 9, the counter 17 is reset by itself and a solenoid actuator 5 is operated during a fixed period of time so that an oil feed pump 2 discharges oil through a jet 11. A counter 18 is adapted to count the frequency of self-resetting of the counter 17 and when the accumulation number amounts to the number of links of the chain link 9, all control circuits are turned off to stop oil feed operation.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for supplying lubricating oil to an endlessly connected and rotating chino, and particularly to a means for evenly supplying lubricant to each link of a high-speed co-moving chino.

A conventional lubrication system for supplying lubricating oil to the sliding parts of a rotatably mounted chino will be explained with reference to FIG. 1J.

A fuel pump 2 is provided on a bracket 3, an electromagnetic actuator 5 is attached to the fuel pump 2, and the fuel pump 2 and the fuel tank 4 are connected by a communicating pipe 4'. The discharge port 2' of the oil supply pump 2 and the oil supply nozzle l are connected by a communicating pipe 1', and an electromagnetic actuator 5 and a proximity switch 8 are connected.
is electrically connected via the control surface 7 ◇ The spout 1' of the lubrication nozzle 1 is connected to the outer link 1 shown in FIG.
1 and the inner link 12, or the gap between the side end of the roller IO and the inner end of the inner link 12.

r between the proximity switch 8 and the roller 10 of the chino 9! iJ
@ is the distance sensitive to the proximity switch 8, and the spout 1'
and the proximity switch 8 is a distance that is an integral multiple of the pitch of the chino 9.

And, the timing to refuel the rotating Cheno 9 is as follows.
It is detected every time it passes a sensitive point with a roller lO moving in direction B near the proximity switch 8, and the electromagnetic actuator 6 is actuated by applying voltage, and the oil 13 filling the oil supply pump z is spouted. It is discharged from f and refuels the position of the cheno 9 where it should be refueled.

The relationship between detection and discharge in the conventional oil supply device configured as described above was as follows.

Discharge from the oil supply pump 2 was detected every time the roller 10 of the cheno 9 passed near the proximity switch 8, and the oil 13 was discharged only once every time IIgl was detected.

However, when the speed at which the roller lO, which is regarded as an object to be sensed and detected, passes near the proximity switch 8 becomes faster, the electromagnetic actuator 5 of the oil supply pump 2 responds, but the °C oil supply pump 2 becomes inoperable. Therefore, there was a drawback that the oil 13 was not discharged.

The oil 13 is discharged from the oil supply pump 2 at maximum times/α5
seconds, and a higher frequency is not satisfactory.

The present invention has been made in view of the drawbacks of the refueling means as described above.
To provide a refueling device capable of accurately refueling even when rotating a chino that moves at high speed in direction B.

As mentioned above, the gist of the present invention is to lubricate and lubricate a rotatably tensioned chino.
This means that oil is added intermittently and cumulatively for every number of pitches.

No matter how fast the speed of Cheno 9 is, in order to ensure discharge, the number of times detected by proximity switch 8 is accumulated on a counter,
The set cumulative number is made to be a prime number, and one discharge is performed based on the set cumulative number.

Next, the present invention will be explained based on FIGS. 2 and 3.

Components that are the same as those of the prior art will be described using the same reference numerals.

First of all, regarding prime numbers, the total number of links in Cheno 9 is Pl
Let us define a prime number that is not a factor of Pl as P2, and then explain the configuration.

Proximity switch 8 or other switches are wired so that current from control surface 19 can be applied to enable detection and generation of a detection signal.

The detection signal from the proximity switch 8 is input to the first counter 17, and the JR1 counter 17 sets the cumulative value of the same number of passes of the roller o as the detection signal to the set value P2.
When it reaches , it performs a self-reset). At the same time as the self-resetting, the electromagnetic actuator 5 also opens for a certain period of time, and the second counter 18 returns to the first counter 1.
The second counter 18, which is electrically wired so as to count by one every time the first counter 17 is reset, resets itself when the cumulative value of the number of self-resets of the first counter 17 reaches a set value P1.

By self-resetting the ratio ε counter 18, the control circuit of the present invention is turned off, and Njf is again turned off.
When lf1 is required, the above-described operation is repeated. To further explain the operation of this configuration on the assumption that the total number of links of the Cheno 9 is 30 links, the prime number 7 is set as the set number of links.

30 links are all the links, and if it rotates endlessly, each link of 30 links will have 1 spout for one revolution.
′ passes through the fixed point nearest to ′.

Now, when the first link among the set 7 links passes the fixed point, the total number of links, 30 links, is divided by 7, and the remainder is 2, which is the remaining 2 links.

Based on the above assumption, if all 30 links rotate 7 times, the oil 13 will be spouted by 30 times.In order to make one revolution, 30 links will deviate from the prime number 7 by 2. In other words, it is only shifted by 2 links from among the 7 links, and due to the rotation of the cheno 9, one discharge is made every time the passing of the 7 links is detected, and the machine is placed at the fixed point of the cheno 9 to be refueled. There is no excessive discharge. The oil is discharged accurately every time.

While Cheno 9 manipulates P2 rotation synchronization, refueling pump 2
The lubrication operation is performed P1 times at intervals equal to the length of the chain defined as Pg, and all links of the chain 9 are lubricated evenly with each discharge, and when stopping at that time, the second counter 18 When the fuel supply is stopped and a second or third discharge is necessary, a second counter is set.

The structure and operation of the present invention have been described above, and the effects are as follows, and the convenience in using the oil pump has been greatly improved.

For high-speed simultaneous movement of Che 2 with bins, rollers, etc.
It is possible to set a prime number from the total number of links in Che 2 and operate according to the set prime number.Also, it is possible to supply oil evenly and evenly to all links, and at the same time, the discharge can be set according to the number of rotations of all links. The same number can now be selected arbitrarily.
