Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a winding device for a loom, and more particularly to an improvement in a manual winding mechanism.

(Prior art) As a conventional winding device, for example, there is one shown in Fig. 1.To explain this, the rotation of the main shaft l of the loom, which is the drive source of the winding device, is controlled by a timing pulley 2 and a timing belt. 3 and timing pulley 4 to the input shaft 6 of the reduction gear box 5. The reduction gear box 5 includes spur gears 7.8a, 8b, 9a, 9b,
10, the input rotation is sufficiently decelerated and outputted from the output shaft 11. The output shaft 11 is equipped with a clutch mechanism 12, which will be described later.
Output gear 13 is attached via. The output gear 130 rotations is the gear 1 constituting the transmission gear train 14.
5 to 19 to the shaft 20, and from this shaft 20 to the gear 2.
1 to a take-up gear 24 fixed to the shaft 23 of the surface roller 22, thereby rotating the surface roller 22. Incidentally, the transmission gear train 14 is provided to correspond to the weft density of the woven fabric, and has gears 16 to 14.
19 is replaced with an appropriate one. Further, a gear 26 integrally provided with a sprocket 5 meshes with the take-up gear 24, and a cross roller (not shown) is rotated from the sprocket 25 via a chain 27.

As shown in FIG. 2, the clutch mechanism 12 includes a reduction gear 4.
・The toothed clutch plate 4 is fixed to the output shaft of the Ponks 5, and the toothed clutch plate 29, which is also integrally provided with the output gear 13, is slidably fitted to the output shaft 11. The toothed clutch plates 28 and 29 are engaged with each other, and the clutch can be disengaged by moving the toothed clutch plate 29 to the right in the figure via the shift fork 31 by operating (depressing) the flange operation pedal 30. This is so that it can be done.

Further, a manual winding wheel 32 is provided, and the rotation of the handle shaft 33 is transmitted through the drive system of the surface roller 22 (in detail, the clutch mechanism 12 and transmission gear train 14
(Between 1 and 2)

Therefore, for manual winding, the
2, the clutch mechanism 12 disconnects the output shaft 11 of the reduction gear box 5 from the subsequent transmission system, and the handle 32 is rotated.

However, the handle 32 fits loosely into the handle shaft 33 as shown in FIG. Since danger is prevented by not transmitting the information to the handle 32, during manual winding, the handle shaft 33 is rotated by pushing the handle 32 and rotating it with the bottle 38 fitted in the hole 39.

However, in such a conventional winding device,
The reduction ratio of the transmission system that transmits the rotation of the manual winding handle to the surface roller is set according to the matching and U work, and delicate adjustments to the position of the weaving cloth are required during the matching work. For this reason, the winding speed using the manual winding handle is very slow. For this reason, when the mechanism has to wind a large amount of warp threads, the handle must be rotated many times, which lengthens the working time, increases stoppage time, and reduces the operating rate of the loom. It was getting worse and my productivity was getting worse.

In other words, when installing new warp threads (warp beam), a tying machine (automatic warp joining machine) is used to improve productivity, and this tying machine connects the old warp threads to the new warp threads. The location is
It is between the crest roller and the warp tross bar. When the weaving process continues, the knots tied by the tying machine can get caught in the warp dropper or heddle mail (pull-through holes), which can cause warp threads to break. Therefore, the knot is manually passed through the warp dowel, sober, heddle, and reed to prevent the warp from breaking due to the knot, but this movement distance is usually 1 m or more, making it difficult to carry out the conventional fitting work. Since the combined manual winding mechanism has a large reduction ratio, it is time consuming and difficult to improve productivity.
It was extremely inconvenient.

<Object of the Invention> In view of such conventional problems, an object of the present invention is to enable both manual fast winding and slow winding.

<Structure of the Invention> For this reason, the present invention provides at least two transmission systems in which the transmission system for transmitting the rotation of the handle for manual winding to the surface roller can be selected and the winding speed of each transmission system is different. <Example> An example will be described below.

FIG. 4 shows a first embodiment. In this embodiment, the same parts as in the conventional example (FIG. 1) are given the same reference numerals, and the explanation will be omitted, and the different parts will be explained.

Separately from the manual winding handle 32, a manual winding handle 40 is also provided, and a bevel gear 42 is fixed to the handle shaft 41. This bevel gear 42 is meshed with a bevel gear 43 that is fixed together with the final stage gear 19 of the transmission gear train 14 to the shaft 20 to which the gear 21 that meshes with the winding gear 24 is fixed. The relationship between the handle 40 and the handle shaft 41 is also similar to that shown in FIG.

According to this configuration, the rotation of the handle 40 is not decelerated by the speed change gear train 14.
Bevel gear 42.43. It is transmitted to the winding gear 24 via the shaft 20 and gear 21, and rotates the surface roller 5 via the shaft 23. Therefore, the amount of winding per one rotation of the handle 40 and the amount of winding per one rotation of the handle 32 are different, and the amount of winding per one rotation of the handle 40 is larger, that is, the winding speed is faster.

Therefore, when winding is being performed, for example, by rotating one handle 32 while operating the clutch operating pedal 30, the winding can be performed at a slow speed. By operating the other pan 1-role 40 while rotating, winding can be performed at a high speed.

A second embodiment is shown in FIGS. 5-8.

In this embodiment, the reduction gearbox is constructed using a differential float mechanism (planetary gear mechanism), and there is only one handle, which can be switched by operating the handle.

The reduction gear box 50 converts the rotation input from the main shaft 1 of the loom to the input shaft 51 via the timing belt 3 into a sixth
As shown in the figure, a two-stage differential +-1; j wheel mechanism (planetary gear mechanism) is used to decelerate and output from the output shaft 52. The gear 5
3, 54a, arm 54b, planetary gear 55, sun gear 56a
, arm 56b, planetary gear 57, sun gear 58a, gear 53
b, 59 to transmit the deceleration to the output shaft 52. Here, a worm wheel 61 is formed on the outer periphery of the internal gear 60 that meshes with the planetary gears 55 and 57.

A worm gear 62 is meshed with the worm wheel 61, and a shaft 63 of the worm gear 62 projects from the reduction gear box 50.

An output gear 65 is attached to the output shaft 52 via a clutch mechanism 64, which will be described later. The rotation of the output gear 65 is transmitted to the take-up gear 24 fixed to the shaft 23 of the surface roller 22 via the gears 67 to 70 constituting the transmission gear train 66, thereby rotating the surface roller 22. .

Further, as shown in FIGS. 5 and 7, a handle 71 for manual winding is provided, and the hunt lure 1 is fixed to a handle shaft 72. The handle shaft 72 is supported so as to be rotatable and movable in the axial direction, and is urged rightward in the figure by a spring 73.

A sprocket 74 is fixed to the handle shaft 72, and this sprocket 74 is connected to a sprocket 75 fixed to the shaft 63 of the worm gear 62 of the reduction gear box 50 and the chain 7.
It is connected by 6.

A bevel gear 77 is also fitted onto the handle shaft 72, and its movement in the axial direction is restricted by a pin 87. Then, this bevel gear 77 is fixed to the shaft 23 of the surface roller 22 integrally with the winding gear 24.
It meshes with 8. Further, a pin 79 is embedded in the end face of the boss portion of the sprocket 74, and a hole 80 into which the pin 79 can be fitted is formed in the end face of the boss portion of the Bebe Lugia 77 facing the pin 79.

The clutch mechanism 64 is constructed as shown in FIG.

That is, the key 8 is connected to the output shaft 52 of the reduction gear box 5o.
1, several sleeves 82 are provided, and the output gear 65 is attached to the sleeves 82 using a key 83. A recess 84 is formed in the key 81.
4 is engaged with an annular projection 86 of a rotary lever 85 screwed onto the end of the output shaft 52. Therefore, if the rotary lever 85 is manually rotated in the opposite direction to the tightening direction, the key 81 slides on the output shaft 52 and the sleeve 8
2, and the output shaft 52 is disengaged from the output gear 65.

The case of manual winding will be described next.

When performing slow winding, such as during alignment work, use the handle 71.
Rotate it as shown without pushing it in. Then, the rotation of the handle shaft 72 is transmitted from the sprocket 74 via the chain 76 and the sprocket 75 to the shaft 63 of the worm gear 62 of the reduction gear box 5o. As a result, the internal gear 6o having the worm wheel 61 in the reduction gear box 5o rotates, the entire differential gear mechanism rotates, and the output shaft 52 rotates. Then, the output gear 65 rotates via the clutch mechanism 64, the take-up gear 24 further rotates via the transmission gear train 66, and finally the surface roller 22 rotates to take up the fabric. can. In this case, the winding speed is slow because the speed is sufficiently reduced by the speed change gear train 66 and the like.

Note that even if the internal gear 6o rotates within the gear box 50, the planetary gear 55 only rotates, so the input shaft 51 does not rotate. Therefore, in the case of this embodiment, there is no need to provide a crack mechanism to break the connection with the main shaft 1. Further, by employing such a differential gear mechanism, manual winding can be performed even while the loom is in operation.

When winding the mechanism quickly, first turn on the clutch mechanism 6.
4, the engagement between the output shaft 52 of the reduction gear box 50 and the output gear 65 is released. So, rotation lever 85
By rotating the key 81 in the opposite direction to the tightening direction, the key 81 is removed from the keyway of the sleeve 82.

Next, push in the handle 71 and insert the pin 79 of the sprocket 74 fixed to the handle shaft 72 into the hole 8 of the hevel gear 77.
0 and rotate the handle 71 in this state.

Then, the rotation of the handle 71 is transmitted to the surface roller 22 via the gears 77 and 78. In this case, since the speed is not reduced, winding can be performed at a relatively high speed.

At the same time, the sprocket 74 drives the entire differential gear mechanism in the reduction gear box 50 via the chain 76, so the output shaft 52 rotates, but the connection with the surface roller 22 is not established by the clutch mechanism 64. Since it is disconnected, there is no problem, and since the input shaft 51 does not rotate as described above, the main shaft 1 does not rotate.

<Effects of the Invention> As explained above, according to the present invention, the transmission system for transmitting the rotation of the handle for manual winding to the surface roller can be selected, and the winding speed of each transmission system is made different, so that at least two Since the system is provided, slow winding and fast winding are possible, and in particular, fast winding has the effect that the working time of the mechanism can be shortened and productivity can be increased.
