Description

[Detailed description of the invention] Industrial applications This invention applies to bobbin rails and flyer rails.

The present invention relates to a roving frame equipped with a lubricating device for lubricating a drive gear fixed to a drive shaft.

In a conventional roving frame, a flyer rail main body rotatably supporting a flyer is covered with five flyer rail covers to constitute a flyer rail as a whole. Further, the bobbin rail main body rotatably supporting the bobbin wheel is covered with a bobbin rail cover, and constitutes the bobbin rail as a whole. In the space inside these flyer rails and bobbin rails, a drive shaft common to all spindles is installed over almost the entire length of the roving frame. ) is fixed to each weight. Conventionally, in order to maintain the lubrication of the meshing parts of these gears, the entire flyer rail cover and bobbin rail cover were removed from the flyer rail body and bobbin rail body, respectively, and grease was applied by hand about once a month. Was. For this work, the braided yarn from the draft part to the flyer plexer is cut once,
After applying the grease and attaching the cover, there was the tedious and time-consuming task of guiding the threads to the plexer for each spindle. Therefore, in order to be able to apply grease without cutting one set of threads,
No. 5 discloses a structure in which greasing holes are provided in portions of the flyer rail cover and bobbin rail cover corresponding to the drive gear, and the holes are covered with a lid.

Problems to be Solved by the Invention According to No. 62-36865, although it is no longer necessary to remove the entire bobbin rail cover, it is necessary to repeatedly remove a large number of covers. Moreover, when removing such a large number of lids manually,
Particularly with flyer rails, roving threads run across the top of the lid, and the lid must be removed while being careful not to touch the braided threads, which is an extremely troublesome task. In addition, it is well known that in helical gears, which are used as driving gears and driven gears, the contact points on the tooth surfaces have burrs in the direction of the tooth trace, which causes the grease to be pushed out to the side of the gear, causing the oil film to break. Cheap. Even if you remove the lid, as mentioned above, if you apply grease over a long period of time, such as once a month, the amount of grease must be quite large so as not to run out of oil before the next lubrication. is applied to. When such a large amount of grease is applied, there is a problem in that due to its viscosity, a large load is placed on the drive motor for a while after the application when the roving frame is started. Furthermore,
There was also the problem that fluff easily adhered to the edge of the lid that covered the hole.

An object of the present invention is to solve these problems.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a greasing system in which grease is sent from a grease tank to a main pipe disposed along a drive shaft in a bobbin rail and a flyer rail in a roving frame. A greasing device is installed on the flyer rail and bobbin rail, respectively, to which the pump is connected, and a large number of branch pipes with discharge ports facing the outer periphery of each drive gear of the drive shaft are connected to the main pipe through metering valves. The present invention is characterized in that it is equipped with a greasing control device that operates a greasing pump for a predetermined period of time during low-speed rotation of the roving frame driving motor in response to a greasing signal.

According to the above structure, the greasing pump is activated by the greasing signal during low speed rotation of the roving frame, and the flyer rail of the roving frame is operated by the greasing signal.
A certain amount of grease is supplied to the drive gear part through the main pipe, metering valve, and branch pipe inside the bobbin rail.

The rotation of the main shaft 1 is transmitted to drive shafts 3.4 of the flyer rail 10 and bobbin rail 20, which will be described later, via a suitable gear train 2.

An electromagnetic clutch 5 is connected to one end of the main shaft 1, and a low speed motor M2 is connected to the electromagnetic clutch 5. The main motor MM and low-speed motor M2 constitute a rover operating motor. These roving frame driving motors and the electromagnetic clutch 5 are under the control of a control means 45 together with a pump motor M in a greasing device 30, which will be described later.

Next, in Figures 2 and 3, the flyer rail 1o of the roving machine is
I will explain about it. Support bushes 12 are fixed to a flyer rail main body 11 extending over almost the entire length of the machine in a longitudinal direction, and a flyer 14 is rotatably supported on the support bushes 12 via bearings 13 and 13. . Flyer 1
A driven gear 15 of a helical gear is fixed to the support portion 14a of No. 4. In the flyer rail body 11, the drive shaft 3, which is common to all the spindles, is rotatably supported by bearings 16 fixed to the flyer rail body 11 at a predetermined interval in the longitudinal direction. This drive shaft 3 includes each fryer 1.
The drive gear 17 of the helical gear meshing with every fourth driven gear 15 is fixed.

A flyer rail cover 18 that covers the flyer rail body 11 is fixed to the flyer rail body 11 with screws 19.

A bobbin rail 20 shown in FIG. 4 is located below the flyer rail 10. This bobbin rail 2
0, a bobbin wheel 24 is rotatably supported via bearings 23, 23 on support shafts 22 which are fixed to the bobbin rail main body 21 in a staggered manner, facing each other vertically below each flyer 14. Each bobbin wheel 24 is integrally provided with a driven gear 25 of a helical gear on its outer periphery. The bobbin rail main body 21 also has the drive shaft 4, which is common to all spindles, rotatably supported over the entire length in the longitudinal direction. A driving gear 26 of a helical gear meshing with 25 is fixed. The bobbin rail main body 21 is covered with a bobbin rail cover 27, and constitutes a bobbin rail 2o as a whole. This bobbin rail 2o is designed to move up and down for bobbin forming movement.

Bobbin rail 20 of such a roving machine. And in the flyer rail 10, the greasing device 30 in the present application is configured as follows. In the flyer rail 10, the second.
As shown in FIG. 3, distributors 31 are fixed at predetermined intervals along the drive shaft 3.

The distributors 31 are connected to each other by main pipes 32 to form a main pipe 33 extending along the drive shaft 3 as a whole. , one distributor 31 has four metering valves 34 screwed together as shown in FIG. This metering valve 34 has a main body 34a and a cap 34b integrated, and a pipe-shaped center 34c is integrally attached to the cap 34b. A piston 34d is fitted into the center 34c so as to be slidable in the axial direction, and a spring 3 is inserted between the center 34c and the cap 34b.
4e is interposed. A V-shaped gasket 34f is provided below the center 34c and is movable in the axial direction, and this movement opens the communication hole 34g of the main body 34a of the metering valve 34 as shown in Fig. S (a) or (c). The hole 34h at the center of the center 34c is closed as shown in FIG. 5(b). A horizontal hole 34j is formed in the front portion of the center 34c to communicate the piston front chamber 34i and the center hole 34h. The front side of the center hole 34h communicates with the nozzle 34k of the cap 34b, and the branch pipe 35 is connected to the cap 34b.

As shown in FIG. 3, this branch pipe 35 is appropriately bent along the way so that the discharge port 35a at its tip opens near the upper outer periphery of the four corresponding drive gears 17. One end of the main pipe 33 is closed, and the other end is connected to a greasing source 40 as shown in FIG. The greasing source 40 includes a greasing pump 41, a pump motor M, and a grease tank 42 for storing grease. And, after the greasing pump 41 stops operating, an automatic depressurization valve 43 is provided which releases the grease into the grease tank 42 so as to lower the grease pressure in the main pipe 33. Such a grease metering, centralized lubrication system is known, for example, as "Breluver" (trade name).

This greasing pump 41 is fixed to the frame of the roving frame. Note that the bobbin rail 20 also has the same piping connections as the flyer rail 10, so a detailed explanation will be omitted. However, with the bobbin rail 20, the main pipe 33 is installed on the front inner wall 21a of the bobbin rail body 21, and the bobbin rail body 21 moves up and down to form the bobbin, so the greasing pump 41 is attached to the machine frame. If it is stuck, the piping between the greasing pump 41 and the main pipe 33 will be
It differs from the flyer rail 10 in that the piping follows vertical movement, such as by using a rubber hose.

Next, the control means 45 will be explained. This control means 45
A greasing control circuit 50 (FIG. 6) as a greasing control device that associates and controls a pump motor M and a low-speed motor M2 that rotates the drive shaft 3.4 at a low speed, and a motor circuit 60. (Figure 7). In Figure 6,
The circuit 51 includes a counter CT for setting the greasing time interval, and the count contact of this counter CT is connected to the a contact AC-1 of the auto counter AC. The greasing time interval is set at a predetermined time interval (for example, once/day),
The number of times the tube becomes full in this time interval is set in advance in the counter CT as a set value. This auto counter AC is 1
As is well known, it is connected to the front roller (not shown) of the draft bar of a roving frame and measures the spinning length of one yarn. It outputs a signal, demagnetizes the main relay MSI (not shown), stops the spinning machine, and closes the a contact AC-1. For the reset 1~contact of counter CT,
A contact TR=1 of timer TR is connected. Next, the circuit 52 is a circuit for driving the low speed motor M2, and the a contact CT-1 of the counter CT, the b contact MS1-4 of the main relay MSI (not shown), and the b contact TR-2 of the timer TR are the low speed relays. It is connected in series to MS2. Next, circuit 53 is a starting circuit for timer TR and electromagnetic clutch 5, in which a contact MS2-7 of low speed relay MS2 is connected to timer TR, and solenoid SQL of electromagnetic clutch 5 is connected in parallel with timer TR. It is.

The motor circuit 60 in FIG. 7 includes a low-speed motor circuit 61 and a pump motor circuit 62, and also includes a main motor circuit controlled by a main relay MSI, although not shown. The low speed motor circuit 61 connects the low speed motor M2 to the a contacts MS2-1 to A of the low speed relay MS2.
It is constructed by connecting 3. In addition, the pump motor circuit 6
2 is a low-speed relay M for the two pump motors M and M.
It is constructed by connecting the a contacts 2-4 to 2-6 of S2.

Therefore, when the low speed relay MS2 is energized, the a contact MS
2-1 to 2-6 are closed, and the low-speed motor M2 and pump motor M are started at the same time.

80 to 90 of the drive shaft 3 by this low speed motor circuit 61.
ppm rotation is achieved.

When the starting switch of the roving frame (not shown) is turned on, relay contacts MS1-1 to MS1-3 of the main relay MSI (not shown) are closed, the main motor MM normally rotates at high speed, and the roving frame performs normal spinning operation. At this time, the electromagnetic clutch 5 is disconnected. When the tube is full, the main relay MSI is demagnetized by the output of the auto counter AC, and at the same time, the circuit 5
No. 1 a contact AC-1 closes. Each time the roving machine becomes full, the counter CT counts, and when the preset value on the counter CT is reached, the a contact CT- of the counter CT is activated.
1 closes. Main relay MSI's b contact MSI-4 is closed due to full stop.

Low speed relay MS2 of circuit 52 is energized. Then, the timer TR starts counting in the circuit 53, and the solenoid SQL of the electromagnetic clutch 5 is excited, so that the electromagnetic clutch 5 is connected. At the same time, the low speed motor circuit 61. The a contacts MS2-1 to MS2-6 of the pump motor circuit 62 close, the low speed motor M2 performs low speed rotation, and the pump motor M rotates to send out grease. The time required for the grease to be discharged from the branch pipe 27 is set in the timer TR, and after a predetermined time has elapsed, the recoverer CT is reset due to time-up. At the same time, low speed relay MS2 is demagnetized, timer TR and solenoid SQL are demagnetized, and rotation of low speed motor M2 and pump motor M is stopped.

When the pump motor M rotates, grease is discharged as follows. As shown in FIG. 5(a), the gasket 34f moves forward due to the pressure feeding of the grease, and the piston 34d moves forward while compressing the spring 34e with the supplied grease, and the piston front chamber 341 is already filled with a constant ff.
1 (approximately 0.2 to 0.3 cc) of grease is poured into the side hole 34.
The liquid is discharged from the cap 34b via j. piston 3
The grease continues to be discharged until the tip 4d hits the rear end of the cap 34b. Since the discharged fixed amount of grease is supplied to the drive gear 17.26 rotating at a low speed, the grease does not scatter. During this time, the piston rear chamber 34fl
is filled with grease. After a certain amount of grease has been discharged in this manner, when the pump 41 is stopped as described above, the pressure inside the pipe is reduced by the action of the automatic depressurization valve 43. Then, as shown in FIG. 5(c), the spring 34e pushes down the piston 34d, and the grease that was in the piston rear chamber 34Q is moved to the piston front chamber 34i through the center hole 34h and the horizontal hole 34j. This series of operations is then executed every time grease is supplied.

In this example, a counter that counts the full signal of the roving frame was used to set the greasing interval, and the greasing signal was obtained by closing the contact at every predetermined operating time, but a timer was used to set the greasing interval. Six other embodiments in which a time interval may be set and a lubrication signal may be output at predetermined time intervals are shown in FIGS. 8 and 9 in the above embodiment.

The lubrication control circuit 50 and the motor circuit 60 are shown in the case where the low speed motor M2 and the electromagnetic clutch 5 are deleted and the main motor MM is operated in normal operation and rotated at low speed. The same numbers will be assigned and the explanation will be omitted. In FIG. 8, the difference from the previous embodiment is that one circuit 53
A point A is connected to a pump relay MS3 instead of the coil SQL of the electromagnetic clutch 5. In addition, in the motor circuit 60, the main motor MM is connected to the main relay MS1.
Normal operation circuit 61 to which the a contacts MSI-1 to 3 are connected
a, reactors X-1 to X-3 and low-speed relay MS2 on the way
A low-speed operation circuit 61b to which the a contacts MS2-1 to 3 are connected
The point is that it has the following.

According to this configuration, when the counter CT reaches the set value, the low speed relay MS2 is energized, and the timer TB and the pump relay MS3 are energized. Then.

The a contacts MS2-1 to MS2-3 close in the circuit 61b, and the main motor MM rotates at a low speed. At the same time, pump relay MS3 in circuit 53A is energized, and pump motor M in circuit 62 is energized.
starts. Then, the bobbin wheel 24 and the flyer 14 are rotated at a low speed, and at this time, grease is supplied from the branch pipe 35 to the drive gear 17.26 which rotates at a low speed.

In this embodiment, the greasing timing may be such that, for example, the thread bobbin is rotated at a low speed for a predetermined time at the beginning of winding, and the greasing pump is operated during the low speed rotation.

In addition, in these two embodiments, since the roving machine is automatically refueled in relation to the operating time as described above, there is no need for manual labor at all, so there is no need to forget to lubricate. The greasing pump may be operated by the greasing signal generated by the push button during low-speed rotation of the roving frame operating motor.

According to the roving frame with a greasing device of this invention, as described above, the effects of the invention are as follows.
The main pipe, metering valve, and branch pipe of the greasing device are installed on the flyer and bobbin rail, and the main pipe is connected to the greasing pump, and this pump is operated by the greasing signal during low-speed operation of the roving frame. Because I did.

A constant amount of grease can be supplied without the trouble of removing the whole flyer rail cover and bobbin rail cover or the trouble of removing the lid as described in the conventional technique. Furthermore, since there is no lid on the flyer rail cover, etc., there is no possibility of air lint adhering to it. In addition, since there is no need to remove the entire flyer rail cover, there is no need to cut the braided threads each time lubrication is performed, and lubrication can be carried out in small amounts at short intervals. Compared to the case where a large amount of lubricating is carried out on a monthly basis (approximately once a month), there is an advantage that no extra load is placed on the drive motor of the roving frame. Furthermore, when refueling.

Since the drive shaft is rotated at a low speed, the grease can be spread over the circumference of the drive gear without scattering.
