Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention includes a greasing device for greasing a flyer rotation gear and a bobbin wheel rotation gear in a flyer rail and a bobbin rail of a roving machine. It relates to a roving machine.

2. Description of the Related Art In a roving machine, a flyer rail main body that rotatably supports a flyer is covered with a flyer rail cover to constitute a flyer rail as a whole. The bobbin rail body that rotatably supports the bobbin wheel is covered with a bobbin rail cover, and forms a bobbin rail as a whole. In the space inside the flyer rail and bobbin rail, a drive shaft common to all weights is provided over substantially the entire length of the roving machine. The drive shaft is provided with driven gears (helical gears) provided on the flyer and the bobbin wheel, respectively. ) Is fixed for each weight, and the flyer and the bobbin wheel are rotated by these gears. Conventionally, in order to maintain the lubrication of the meshing portions of these gears, the entire flyer rail cover and bobbin rail cover are removed from the flyer rail body and bobbin rail body at a rate of about once a month, and grease is applied manually. I was In this work, especially on flyer rails, the roving from the draft part to the presser of the fryer is cut once, grease is applied, the cover is attached, and then the roving is guided for each weight to the presser. Work that required time was accompanied. Therefore, in order to apply grease without cutting the roving yarn, Japanese Utility Model Publication No.
There is disclosed a structure in which a greasing hole is provided in a portion corresponding to a drive gear of a flyer rail cover and a bobbin rail cover, and the hole is covered with a lid.

According to Japanese Utility Model Publication No. Sho 62-36865, the operation of removing the entire bobbin rail cover and the like is not performed, but a considerable number of operations of removing the lid must be repeated. Moreover, when removing a large number of lids by hand as described above, especially with flyer rails, a roving thread extends over the lid, and the lid must be removed carefully so as not to touch the roving thread. The work is extremely cumbersome. Also, as is well known, the helical gear used as the driving gear and the driven gear has slippage in the tooth flank direction at the contact point of the tooth surface, so that grease is pushed out to the side of the gear and the oil film is easily cut. . Therefore, even if the lid is removed as described above, when the grease is applied at a long cycle such as once per month as described above, the amount of the grease may be reduced by the next greasing. It is applied in a considerable amount so as not to run out of oil. When such a large amount of grease is applied, there is a problem that a large load is applied to the drive motor when the roving machine is started for a while after the application due to its viscosity. In addition, the conventional technique has a problem that fly waste easily adheres to the edge of the lid that covers the oil supply hole.

An object of the present invention is to solve such a problem.

Below the flyer rail 10, a bobbin rail 20 shown in FIG. 4 is located. In the bobbin rail 20, a bearing 23, a support shaft 22 fixed vertically in a staggered manner to the bobbin rail main body 21 facing vertically below the respective flyers 14,
A bobbin wheel 24 is rotatably supported via 23. Each bobbin wheel 24 is integrally provided with a driven gear 25 of a helical gear on its outer periphery. This bobbin rail body 21
Also, the drive shaft 4 common to all weights is rotatably supported over the entire length in the longitudinal direction, and the drive shaft 4 has a driven gear 25 of each bobbin wheel 24 similarly to the flyer rail 10.
The drive gear 26 of the helical gear meshing with the gear is fixed.
The bobbin rail main body 21 is covered with a bobbin rail cover 27, and forms the bobbin rail 20 as a whole. The bobbin rail 20 moves up and down for bobbin forming motion.

In the bobbin rail 20 and the flyer rail 10 of such a roving machine, the greasing device 30 in the present application is configured as follows. In the flyer rail 10, distributors 31 are fixed at predetermined intervals along the drive shaft 3, as shown in FIGS. The distributors 31 are connected to each other by a main pipe 32 to form a main pipe 33 along the drive shaft 3 as a whole. Four metering valves 34 are screwed into one distributor 31 as shown in FIG. This metering valve 34 is
a and the cap 34b are integrated, and a pipe-shaped center 34c is integrally attached to the cap 34b. A piston 34d is slidably fitted in the center 34c in the axial direction, and a spring 34e is interposed between the center 34c and the cap 34b. Below the center 34c, a V-shaped packing 34f is movable in the axial direction. This movement allows the main body 34a of the metering valve 34 to communicate with the communication hole 34g as shown in FIG. 5 (a) or (c). As shown in FIG. 5 (b), the center hole 34h of the center 34c is closed. In the center 34c, a lateral hole 34j that connects the piston front chamber 34i and the center hole 34h is formed in the front part. Center hole 34

An automatic depressurizing valve 43 for relieving 42 is provided. Such grease metering, centralized lubrication systems are known, for example, as "Greluvers" (trade name).
The greasing pump 41 is fixed to the frame of the roving machine.
The bobbin rail 20 also has the flyer rail 10
Since the same pipe connection is made as described above, detailed description is omitted. However, in the bobbin rail 20, the mounting position of the main pipe 33 is the front inner wall 21a of the bobbin rail main body 21, and since the bobbin rail main body 21 moves up and down for bobbin formation, the greasing pump 41 is fixed to the machine frame. In this case, the piping between the greasing pump 41 and the main pipe 33 is different from the flyer rail 10 in that the piping follows a vertical movement such as using a rubber hose.

Next, the control means 45 will be described. This control means 45
A grease control circuit 50 (FIG. 6) as a grease control device for controlling and relating the pump motor M and the low speed motor M2 for rotating the drive shafts 3 and 4 at low speed;
60 (FIG. 7). In FIG. 6, the circuit 51 includes a counter CT for setting a lubrication time interval, and a count contact of the counter CT is connected to an a-contact AC-1 of an auto counter AC. The lubrication time interval is set to a predetermined time interval (for example, once / day), and the number of times of filling at this time interval is set in the counter CT as a preset value in advance. As is well known, the auto counter AC is connected to a front roller (not shown) of a draft part of the roving machine, and measures the spinning length of the roving yarn. At this time, a full signal is output, the main relay MS1 (not shown) is demagnetized to stop the spinning operation of the roving machine, and the a-contact AC-1 is closed. Counter CT
Is connected to an a-contact TR-1 of the timer TR. Next, a circuit 52 is a circuit for driving the low-speed motor M2, and has an a-contact CT-1 of the counter CT, a b-contact MS1-4 of the main relay MS1, not shown, and a b-contact TR- of the timer TR.
2 is connected in series to the low speed relay MS2. Next, the circuit 53
A starter circuit for the timer TR and the electromagnetic clutch 5 has an a-contact MS2-7 of the low-speed relay MS2 connected to the timer TR, and a solenoid SOL for the electromagnetic clutch 5 connected in parallel with the timer TR.

The motor circuit 60 shown in FIG. 7 includes a low-speed motor circuit 61 and a pump motor circuit 62. Although not shown, the motor circuit 60 also includes a main motor circuit controlled by a main relay MS1. The low-speed motor circuit 61 is configured by connecting low-speed motors M2 to a-contacts MS2-1 to MS3-3 of the low-speed relay MS2. The pump motor circuit 62 includes two pump motors M, M, a contact MS2-4 of the low speed relay MS2.
6 are connected. Accordingly, when the low-speed relay MS2 is excited, the a contacts MS2-1 to 6 close, and the low-speed motor M2 is closed.
2 and the pump motor M are started simultaneously. By this low speed motor circuit 61, 80 to 90 rp of the drive shaft 3
A rotation of m is realized.

When the start switch of the unillustrated roving machine is turned on, the relay contacts MS1-1 to 3 of the unillustrated main relay MS1 are closed,
The main motor MM normally rotates at a high speed, and the roving machine normally performs a spinning operation. At this time, the electromagnetic clutch 5 is disconnected. When the full state is reached, the output of the auto counter AC demagnetizes the main relay MS1, and at the same time, the a contact A of the circuit 51
C1- closes. Each time the roving machine is full, the counter CT is counted, and when the count value reaches a preset value set in the count CT, the a-contact CT-1 of the counter CT closes. Since the b-contacts MS1 to MS4 of the main relay MS1 are closed due to the stoppage of the full package, the low-speed relay MS2 of the circuit 52 is excited. Then, the timer TR starts counting in the circuit 53, the solenoid SOL of the electromagnetic clutch 5 is excited, and the electromagnetic clutch 5 is connected. At the same time, the a contacts MS2-1 to MS6 of the low-speed motor circuit 61 and the pump motor circuit 62 are closed, the low-speed motor M2 performs low-speed rotation, and the pump motor M rotates to send out grease. The time required for grease to be discharged from the branch pipe 35 is set in the timer TR, and after a predetermined time has elapsed, the counter CT is reset by time-up. At the same time, the low-speed relay MS2 is demagnetized, the timer TR and the solenoid SOL are demagnetized, and the rotation of the low-speed motor M2 and the rotation of the pump motor M are stopped.

When the pump motor M rotates, grease is discharged as follows. As shown in FIG. 5 (a), the packing 34f moves forward by the grease pressure feed, and the piston 34d moves forward while compressing the spring 34e by the supplied grease, so that the piston front side chamber 34i has already filled a certain amount ( 0.2-0.3cc
Grease) is discharged from the cap 34b through the horizontal hole 34j. Grease discharge continues until the piston 34d hits the rear end of the cap 34b. The discharged fixed amount of grease is supplied to the driving gears 17 and 26 rotating at a low speed, so that the grease does not scatter. During this time, the piston rear side chamber 34l is filled with grease. After the fixed amount of grease has been discharged in this way, when the pump 41 is stopped as described above, the pressure in the pipe is reduced by the action of the automatic pressure release valve 43. Then, as shown in FIG. 5 (c), the spring 34e pushes down the piston 34d, and the grease in the piston rear side chamber 34l is moved to the piston front side chamber 34i via the center hole 34h and the horizontal hole 34j. Hereinafter, this series of operations is executed each time grease is supplied.

In this embodiment, the greasing interval is set by using a counter that counts the full signal of the roving machine, and the contact is closed at every predetermined operation time to obtain a greasing signal. A time interval may be set and the greasing signal may be output at predetermined time intervals.

Other Embodiments In FIGS. 8 and 9, the lubrication control circuit 50 in the case of the above-described embodiment in which the low-speed motor M2 and the electromagnetic clutch 5 are deleted and the main motor MM is rotated at a normal speed and at a low speed. 4 shows a motor circuit 60. The same parts as those in the above embodiment are denoted by the same reference numerals, and the description is omitted. In FIG. 8, the difference from the above embodiment is that a pump relay MS3 is connected to the circuit 53A instead of the coil SOL of the electromagnetic clutch 5. In the motor circuit 60, the main motor
The normal operation circuit 61a in which the a-contacts MS1 to MS3 of the main relay MS1 are connected to the MM, and the low-speed operation circuit in which the a-contacts MS2-1 to MS2-3 of the low-speed relay MS2 are connected to the reactors X-1 to X-3 in the middle.
62b.

According to this configuration, when the counter CT reaches the set value, the low-speed relay MS2 is excited, and the timer TR and the pump relay M
S3 is excited. Then, in the circuit 61b, the a contacts MS2-1 to MS2-1 to MS3-3
Is closed, and the main motor MM rotates at a low speed. Circuit at the same time
The pump relay MS3 of 53A is excited, and the pump motor M of the circuit 62 is started. Then, the bobbin wheel 24 and the flyer 14 are rotated at a low speed, and at that time, the grease is supplied from the branch pipe 35 to the drive gears 17 and 26 that rotate at a low speed.

In this embodiment, the lubrication may be performed, for example, by performing low-speed rotation for a predetermined time at the beginning of winding of the rough bobbin, and operating the greasing pump during the low-speed rotation.

In addition, in these two embodiments, since there is no need for manual labor at all in order to automatically lubricate in connection with the operation time of the roving machine as described above, there is an advantage that there is no forgetting to greasing,
The greasing pump may be operated during the low-speed rotation of the roving machine operating motor by a greasing signal generated by a manual push button.

Effect of the Invention As described above, according to the roving machine with a greasing device of claim 1 of the present invention, the main pipe, the measuring valve, and the branch pipe of the greasing device are arranged on the flyer and the rail, and the main pipe is connected to the greasing pump. , And this pump is operated by the lubrication signal,
A certain amount of lubrication can be performed without any trouble of removing the entire flyer rail cover or removing the lid of the flyer rail cover as described in the related art. Further, since the flyer rail cover has no lid, fly waste does not adhere. And since there is no work of removing the entire flyer rail cover in this way, it is not necessary to cut the roving every time the greasing is performed, and the greasing can be performed little by little in a short cycle. Compared with the case where a large amount of lubrication is performed once per month (about once / month), there is an advantage that the influence of grease viscosity can be reduced and no extra load is applied to the drive motor of the roving machine.

According to the second aspect, since a similar greasing device is provided on the bobbin rail in addition to the flyer rail, the removal of the entire bobbin rail cover and the removal of the lid of the bobbin rail cover in the related art can be eliminated. In addition, the greasing operation can be performed without much trouble, and the load on the drive motor can be further reduced. Furthermore, in the third aspect, the grease can be attached to the gear for rotating the flyer or the gear for rotating the bobbin wheel without scattering the grease because the drive shaft is rotated at a low speed when greasing.
