Description

[Detailed Description of the Invention] Technical Field This invention relates to a device for preventing drooping of preliminary roving of a spinning machine creel in a spinning machine that supplies roving from a roving winding.

Prior Art In a spinning machine such as a spinning machine that supplies roving from a roving winding, a roving winding 3 is suspended from a bobbin hanger 2 attached to a creel 1, as shown in FIG. is introduced into a drafting section (not shown) via a guide 5. Then, when the amount of winding of the supplied roving winding 3 decreases, the preliminary roving winding 6 is removed from the creel 1.
It is suspended from a bobbin hanger 8 for a spare roving winding attached to a bracket 7 protruding from the front part of the roving winding, and when the supplied roving winding 3 is almost exhausted, the unfinished or cut end of the supplied roving winding 3 is joined to the mouth end of the preliminary roving winding 6. By doing so, the roving change work is streamlined. However, if the preliminary roving winding 6 is left in a free state, the end 9 may be rewound due to the vibration of the machine stand, fall, become tangled with other supplied rovings 4, or be drafted. This had the disadvantage that it could cause thread breakage and damage the product.

In order to eliminate the above-mentioned drawbacks, the roving end 9 can be supported by being sandwiched between the rovings, or by being wrapped around the brake of a bobbin hanger 8 for preliminary roving winding which has a brake as shown in FIG. was carried out. However, such end support is not only time-consuming but also inconvenient when changing the roving. Therefore, as shown in Figs. 3 and 4, a steel plate 10 bent in a dogleg shape is attached to the bobbin hanger 8 for preliminary roving winding.
A presser rod 11 formed in a U-shaped cross section at its lower end.
A roving sag prevention device has been proposed in which the roving is attached via a support shaft 12, and the presser rod 11 presses the body of the preliminary roving 6 to support the mouth end 9. However, since the above-mentioned roving sag prevention device needs to be attached to each bobbin hanger 8 for winding the preliminary roving, it is time-consuming, expensive, and troublesome to install it.

Purpose This invention was made in order to eliminate the above-mentioned conventional defects, and its purpose is to securely hold the end of the preliminary roving winding, prevent the end from drooping, and to make it possible to securely hold the end of the preliminary roving, and to To provide a device for preventing drooping of spare roving of a creel for a spinning machine, which does not require installation of a device for each bobbin hanger for winding roving, has a simple structure, and is inexpensive.

Embodiment An embodiment embodying this idea will be described below with reference to FIGS. 5 and 6. A column 22 is erected on both sides of the upper part of the frame 21 of the spinning machine, and a support arm 2 extending in a direction perpendicular to the longitudinal direction of the frame 21 is attached to the upper part of the column 22.
3, and rails 24a, 24 arranged in parallel so as to extend along the longitudinal direction of the machine base 21 between the support arms 23.
A creel 25 consisting of b is provided.
Further, as shown in FIG. 6, an auxiliary support 26 is installed between the two supports 22, and the auxiliary support 26 is provided with an auxiliary support arm 2 that supports the rails 24a, 24b.
7 is installed. The rails 24a, 2
4b are arranged in parallel on both sides of the support 22, with the two inner rails 24a having a roving winding 28 for supplying roving, and the outer rail 24b having a spare roving winding 29 for feeding a bobbin hanger 30. They are each suspended through the The roving 31 pulled out from the roving winding 28 for supplying roving is supplied to a roller part 34 via guide rods 32 and 33.

Support rods 35 are attached to both ends of the outer rail 24b so as to hang down from the lower end of the trunk of the preliminary roving winding 29. A bracket 36 is fitted into each of the support rods 35 so as to be vertically slidable, and is fixed in any position with a bolt 37. As shown in FIG. 6, between the brackets 36, both ends are fixed to the brackets 36, and one side is connected to the outer rail 2.
A plate-shaped pressing member 38 is stretched along the longitudinal direction of the rail 24b and is in contact with the body of the preliminary roving winding 29 suspended from the bobbin hanger 30 on the rail 24b.
At this time, the length of the arm of the bracket 36 is made smaller than the radius of the body of the preliminary roving winding 29, so even if there is a slight difference in the diameter of the body of the preliminary roving winding 29, the body is always connected to the plate-shaped pressing member. 38 and can prevent the roving from hanging down. Further, the pressing member 38 may be a flexible member such as a tape-like member or a rope-like member, or may be a rigid member.

In this way, in the present device, the rail 24b
The body of the preliminary roving winding 29 suspended from the roving 29 comes into contact with the pressing member 38, so that it is always pressed even if the diameters of the bodies are different. Therefore, the rotation phenomenon of the preliminary roving winding 29, which promotes roving sag, is reliably prevented. If the pressing member 38 is positioned as low as possible below the preliminary roving winding 29 as shown in FIG. 5, even if the mouth end 29a begins to droop due to vibrations, the roving will come into contact with the pressing member 38. Dragging of the roving is then completely prevented. Moreover, the preliminary roving winding 2 suspended on the rail 24b
9, all of their bodies are pressed by the pressing member 38, so unlike the conventional device, the individual preliminary roving windings 29
There is no need to provide a mouth-holding device for each case. Furthermore, since the structure is extremely simple, there are almost no failures and the cost is low.

Note that this invention is not limited to the above embodiment, and for example, as shown in FIG.
Both ends of 8 are bent at right angles and a long hole 3 is formed.
9 is formed and the pressing member 38 is fixed to the bracket 36 through the elongated hole 39 with the mounting position adjustment bolt 40 so as to be adjustable in its movement in the front and back direction, or the support rod 35 is set upright from the machine base 21, and the pressing member 38 is fixed to the bracket 36 through the elongated hole 39. Part 3
8 directly to the support rod 35 or by pressing the preliminary roving winding 29, the pressing member 3
8, or attach a sponge, rubber, etc. to the pressing member 3.
It is also possible to arbitrarily change the shape, structure, etc. of each part without departing from the spirit of this invention, such as forming 8 with a circular cross section.

Effects As detailed above, in this invention, a pressing member is stretched along the longitudinal direction of the creel so as to be in contact with the body of the preliminary roving wound suspended on the creel, thereby preventing the rotation of the preliminary roving. In addition to reliably preventing the roving from drooping, the roving that has started to sag can hit the pressing member and prevent it from sagging any further.Furthermore, unlike conventional methods, it is necessary to attach an end holding device to each bobbin hanger for winding the preliminary roving. Moreover, since the structure is simple, there are almost no failures, and the cost is low.
