Description

Description: TECHNICAL FIELD The present invention relates to an oil supply system in a loom.

(Prior Art) Lubricating oil is supplied to a lubricating portion of a loom by a manual feed or an independent lubricating mechanism. As the lubricating mechanism, there is a contact lubricating method by oil oozing or an intermittent supplying method by pumping.

(Problems to be Solved by the Invention) However, manual lubrication is inconvenient because the frequency of lubrication to lubricating parts between members having a high operating speed is high. In the contact lubrication system, applicable lubrication parts are limited, and in the intermittent lubrication system, there is a problem that it is not known whether or not lubrication has been performed reliably.

An object of the present invention is to provide a refueling system that can solve these problems.

(Means for Solving the Problems) For this purpose, the present invention provides a delivery device that sends out lubricating oil, a circulating main passage for supplying lubricating oil sent from the sending device, and a lubricating oil that is guided from the main passage to a lubricating portion. A branch passage, an electromagnetically driven opening / closing control mechanism interposed on the branch passage and controlling the movement of the lubricating oil, a lubrication detector interposed between the opening / closing control mechanism and the lubrication portion, And a control computer that issues a lubrication command in the specified lubrication cycle and determines whether or not lubrication is to be performed on the lubricated portion in accordance with a detection signal from the lubrication detector.

(Operation) The control computer sends an opening command to the opening / closing control mechanism when the refueling time comes. As a result, the opening / closing control mechanism is opened, and the lubricating oil is supplied to the lubricating portion through the branch passage by the supply pressure in the main passage. If the lubricating oil is not supplied from the open / close control mechanism to the lubrication site for any reason, a lubrication detector provided between the open / close control mechanism and the lubrication site accurately detects this lubrication failure, and the control computer The refueling failure is determined based on the detection signal.

FIG. 2 is a flowchart showing a refueling work program. Hereinafter, the refueling work will be described with reference to this flowchart.

The loom control computer C issues a start command based on the ON signal of the start switch 43, simultaneously with commanding the opening and closing of the electromagnetic valve V _0, starts counting. Electromagnetic valve V ₀ is opened and closed in a predetermined cycle, the pressure air is intermittently supplied to the supply pump 29. Thereby, the lubricating oil in the tank 28 is sucked into the supply pump 29, and is pushed out from the supply pump 29 to the main pipe 31, so that the lubricating oil moves intermittently in the main pipe 31. When the measurement time T reaches the lubrication cycle Ti (i = 1 to 5), the loom control computer C instructs the electromagnetic valve Vi to open, and the electromagnetic valve Vi opens. As a result, the lubricating oil is sprayed from the oil supply nozzle Ni to the lubricating portion Li at the supply pressure, and the lubricating portion Li is supplied with oil.

When lubrication is being performed well, the piston Sa of the lubrication detector Si turns on the limit switch Sb by the supply pressure,
This ON signal is sent to the loom control computer C. The loom control computer C starts timing when the input signal ti is input.
If it is within the set time t from Ti, that is, within the time [Ti, Ti + t], it is determined that the refueling has been successful, and a command to close the electromagnetic valve Vi is issued at the time ti. This stops the lubrication to the lubrication site Li.
Then, the loom control computer C stores the lubrication success information, performs timing initialization, further transfers fueling success information to the central management computer C _0.

If the supply pressure does not reach the refueling detector Si for any reason, the limit switch Sb of the refueling detector Si is turned on.
I will not do it. Accordingly, the ON signal of the limit switch Sb is not input to the loom control computer C within the period [Ti, Ti + t], and the loom control computer C determines that refueling has failed due to the time over and the time (Ti +
At t), a command to close the electromagnetic valve Vi is issued. This stops the lubrication to the lubrication site Li. Then, fiber control computer C stores with a warning displayed on the display unit 44 the oil supply failure information, performs timing initialization, to further transfer the oil supply failure information to the central management computer C _0. The central control computer _C0 stores the transferred refueling failure information and displays a warning on the display unit 45. The operator can take measures against poor refueling based on this warning display.

According to the lubrication system of the present embodiment, lubrication to the lubricating parts Li is automatically and collectively performed at a period Ti suitable for each lubricating part Li, and when a lubrication failure occurs, this is immediately grasped. be able to. Therefore, appropriate refueling can be performed while significantly reducing human input for refueling work.

The present invention is, of course, not limited to the above-described embodiment. For example, the present invention is applied to lubrication of lubricating parts in a driving unit such as an easing device, a winding device, and a torsion ear forming device without being limited to the opening device. Embodiments are also possible in which a lubrication system is used to supply oil to all lubrication sites from a single delivery device, or a pressure sensor is used as a refueling detector. Further, refueling may be performed by instructing the operation of the feeding device in place of the opening / closing command of the opening / closing control mechanism. It is also possible to select each method of timing only during operation according to the refueling point.

(Effects of the Invention) As described in detail above, the present invention intervenes between the lubrication portion and the opening / closing control mechanism of the branch passage by determining whether or not to lubricate the lubrication portion and whether or not to lubricate the lubrication portion at a predetermined lubrication cycle. The data from the refueling detector is judged by the control computer by the control computer.Thus, smooth refueling can be achieved while minimizing human input to refueling work. There is an excellent effect that this can be accurately grasped and appropriate measures can be taken.
