Description

[Detailed Description of the Invention] Technical Field This invention relates to a cover for a flyer rail and a bobbin rail of a roving frame.

Prior Art In general, in a roving frame, as shown in Fig. 1, a flyer 2 is rotatably supported via a bearing 3 on a flyer rail 1 disposed at the top of the machine frame, and a common upper drive for all spindles is provided. A driven gear 6 that meshes with a drive gear 5 fixed to the shaft 4 for each weight is fitted on the upper part of the fryer 2, so that the rotation of the upper drive shaft 4 causes the fryer 2 to rotate all the weights at once. There is. Further, the flyer 2 is attached to the bobbin rail 7 which moves up and down below the flyer rail 1.
A stud 8 is fixed at a position facing the stud 8, and a bobbin wheel 10 into which a bobbin 9 is fitted is rotatably supported by the stud 8 via a bearing 11. A driven gear 10a is integrally formed at the lower end of the bobbin wheel 10 and meshes with a drive gear 13 fixed to each spindle on a lower drive shaft 12 common to all the spindles. It is becoming more and more driven by A flyer rail cover 14 and a bobbin rail cover 15 that cover the drive mechanism are attached to the flyer rail 1 and bobbin rail 7 with screws 16, respectively.

Therefore, the driving gears 5, 13 and the driven gears 6, 10a
If grease is to be applied periodically to maintain lubrication of the meshing portion, it is necessary to remove the screws 16 and remove the entire flyer rail cover 14 and bobbin rail cover 15. In order to remove the flyer rail cover 14, it is necessary to cut the roving thread R that extends from the draft part 17 to the tip of the presser 2a of the flyer 2, and to finish applying grease to the drive gear, the flyer rail cover 1
4 in its original state, it was necessary to guide the roving R to the tip of the presser 2a for each spindle, which was very troublesome. Also, bobbin rail cover 1
In the case of a normal roving frame as shown in FIG.
Although this is easier than in the case of 2, the entire bobbin rail cover 15 must be removed. Also, the fourth
As shown in the figure, the Tokuko Sho published on May 24, 1982
During doffing, as in the device described in Publication No. 57-24414, a full bobbin is separated from a bobbin wheel and placed on a bobbin holder installed on an endless chain conveyor, and the bobbin holder is moved to the bobbin rail by the operation of the chain conveyor. In the case of a device equipped with a mechanism that moves the top surface of the cover to transfer a full bobbin to the end of the roving frame, there is an inconvenience that the bobbin holder must be removed when the bobbin cover is removed, which is very time-consuming. .

Purpose This invention was devised in view of the above-mentioned problems, and its purpose is to develop a roving machine that can extremely easily apply grease to the drive gears of the flyer and bobbin wheel during periodic inspections, etc. An object of the present invention is to provide a cover for a flyer rail and a bobbin rail.

Structure of the device In order to achieve the above object, in this device, a through hole for oil supply is formed at a position corresponding to a drive gear fitted and fixed for each spindle with respect to a common drive shaft for all spindles, and A lid was provided to cover the through hole.

Embodiment 1 A first embodiment in which this invention is embodied in a flyer rail cover 14 will be described below with reference to FIGS. 2 and 3. As shown in FIG. 2, rectangular through holes 18 are formed in the flyer rail cover 14 along the upper drive shaft 4 so as to correspond to the two drive gears 5, respectively. A lid body 19 covering the through hole 18 is provided on both sides of the periphery of the through hole 18 along the upper drive shaft 4.
A pair of step portions 1 for supporting the flyer rail cover 14 so that its upper surface is flush with the upper surface of the flyer rail cover 14.
8a is formed. The lid 19 is formed of an iron plate so that it can be attracted by a magnet. In the flyer rail cover 14 formed in this manner, when applying grease to the drive gear 5 during periodic inspection, etc., the cover 1 covering the through hole 18 is
Grease application work can be performed extremely easily by simply removing 9. Furthermore, in this embodiment, the top surface of the lid body 19 is flush with the top surface of the flyer rail cover 14, so in order to prevent fluff from accumulating on the top surface of the flyer rail cover 14, The flow of air ejected from the air ejection holes 14a provided at the front end is not disturbed. Moreover, since the lid body 19 is made of iron plate, the through hole 18 can be attached extremely easily by attracting it with a magnet.
It can be removed from.

Embodiment 2 Next, when this invention is doffed, a full bobbin is placed on a bobbin holder 21 installed on an endless chain conveyor 20 separated from the bobbin wheel 10, and the bobbin holder 21 is moved to the bobbin rail by the operation of the chain conveyor 20. A second embodiment of the bobbin rail cover 15 of an apparatus having a mechanism for moving the upper surface of the cover 15 to transfer a full bobbin to the end of the frame of a roving frame will be described with reference to FIGS. 4 and 5. The bobbin rail 7 consists of a bobbin rail 7 body that supports a lower drive shaft 12, a drive gear 13, and a bobbin wheel 10, and a conveyor rail 22 that is placed on top of the bobbin rail 7 body and is provided so as to be separable from the bobbin rail 7 body during doffing. The chain conveyor 20 moves within guide rails 23 provided on both sides of the conveyor rail 22. A bobbin holder 21 whose outer end is fixed onto the chain piece 20a of the chain conveyor 20 at an interval that matches the arrangement interval of the bobbin wheels 10 is attached to a groove 15a formed in the bobbin rail cover 15.
A slider 24 extending upward through the bobbin rail cover 15 and fixed to the lower surface of the inner end is supported so as to be slidable in the longitudinal direction while abutting a pair of protrusions 25 formed along the longitudinal direction of the bobbin rail cover 15. has been done. Rectangular through holes 27 are formed in the recesses 26 between the projections 25 along the lower drive shaft 12 so as to correspond to the two drive gears 13, respectively. In order to cover the through holes 27, a large number of lid bodies 28 are provided to cover the ten spindles, that is, five through holes 27.
is embedded in. Therefore, in the bobbin rail cover 15 formed in this way, when refueling,
By simply removing the common lid for the 10 spindles, you can easily refuel from the through hole 27 that is common to the 2 spindles, and compared to the conventional device, the bobbin holder 21
The work efficiency is extremely good in that there is no longer a big task of removing the parts. Although the lid 28 is fitted into the recess 26, it may be secured at both ends with screws 29.

Note that this invention is not limited to the above embodiments, and in the case of the bobbin rail cover 15, the top surface of the lid body 28 and the top surface of the cover do not necessarily have to be flush with each other. A knob for opening and closing may be provided on the top surface. Further, instead of forming the lids 19 and 28 from iron plates, they may be formed from a material that is not attracted to magnets, and a magnet may be fixed to the back surface thereof, or the iron plates may be coated with synthetic resin.

Effects As detailed above, according to this invention, it is extremely easy to apply grease to the drive gear of the flyer and bobbin wheel during periodic inspections etc. through the through hole provided at the position corresponding to the drive gear. Therefore, unlike conventional devices, there is an excellent effect in that there is no need to guide the roving to the presser at the lower end of the flyer after cutting the roving from the draft part to the flyer and applying grease.
