Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a full bobbin take-out device for a roving frame.

Recently, full bobbins from roving machines are all taken out by an easy dotting method in which the flyer is suspended.

That is, for example, there are types in which the bobbin shaft or bobbin rail is pulled out from the spindle with the bobbin shaft or bobbin rail in the lowest position, types in which the bobbin or bobbin rail is tilted forward at that time, and other types in which the bobbin rail is lowered in the lowest position. At the same time, the holding plate is raised on a track to hold the full bobbin at a height that makes it easy to take it out.

However, although it is easy to take out a full bobbin using the above-mentioned dotting method, in either case, it is difficult to bend down to take out a full bobbin from a lowered bobbin rail, or to remove a full bobbin using a holding plate. Even when holding the bobbin, it is necessary to insert one's hand into the machine frame, and it is not easy to take out a heavy full bobbin weighing approximately 2.2 to 3.0 kg, which requires a lot of labor from the worker. Ta.

The present invention corrects these drawbacks by mechanically moving the full bobbin on the bobbin rail to a position at an appropriate height outside the machine stand,
This makes it possible to easily transfer a full bobbin to a transport vehicle without bending over or taking any other unreasonable postures.
It is also an extremely effective device for installing automatic doffing equipment in the future.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the configuration of the present invention shown in the drawings will be described below.

1 to 4 sequentially show the operation of the main full bobbin take-out device opening in the roving frame A.

As shown in Fig. 1A and B, this roving frame machine A has two spindle rows 1 so that doffing can be done from the front and back of the machine frame.Both the flyer 2 and bobbin 3 rotate clockwise, and the bobbin rail 4 winds up the roving while the bobbin 3 moves up and down.
When the bobbin is full, the bobbin rail 4 automatically stops at a fixed position.

In the drawing, 5 is a flyer rail for rotating and suspending the fryer 2, and 2a is a flyer plenosa.

A full bobbin take-out device port is attached to the roving frame A. The device port moves the bobbin holder 6 and the bobbin holder 6 forward toward the spindle row from the front of the machine frame, as shown in FIG.
It consists of a reciprocating drive mechanism 7 for retracting.

The reciprocating drive mechanism T includes, for example, as shown in the figure, a shifter rod 8 that is attached to be able to reciprocate along the machine base, a shifter arm 9 that transmits the movement of this rod 8 to the bobbin holder 6 as forward and backward movement, a support lever 10, etc. .

That is, a support shaft 12 is rotatably installed on a bracket 11 attached to a part of the machine base, a shifter arm 9 and a support lever 10 are attached to this support shaft 12, and these are attached to a pin 13 on a shifter rod 8 and a bobbin holder 6, respectively. , 14 and the sliding long windows 13a, 14a.

As a result, when the shifter rod 8 is moved in the direction of arrow a or the opposite direction, the bobbin holder 6 is perpendicular to the direction of arrow a or b, and moves approximately linearly in the direction of arrow a' or b', respectively. do.

This reciprocating drive mechanism may be of the arm rotation type as in the above embodiment, or the link mechanism may be a rack, pinion mechanism, etc.; The arm rotation type of the embodiment is preferable.

Further, the bobbin holder 6 is provided facing the two spindle rows 1, and one unit thereof has a length of four hogs.

Further, a bobbin fitting support part 15 is cut into a semicircular shape at the same interval as the spindle on the long side edge.

As shown in the figure, this fitting support part 15 has a notch large enough to fit into the lower part of the spindle on the lower side, and a stepped notch large enough to fit into the lower part of the bobbin on the upper part, and half of the lower notch. Slide the circular periphery with the bobbin support part 15'.

The bobbin holder 6 and reciprocating drive mechanism 7 configured as above
As shown in FIGS. 1A and 1B, the bobbin holder 6 is located at the height of the stop position of the bobbin rail 4 when the bobbin is full, that is, on the bobbin rail 4 that stops above the bobbin rail 4 on its way up and down. It is attached to both the front and back sides of the spindle over the entire length of the machine so as to face the lower end of the spindle.

That is, as shown in the drawing, the bobbin holder 6 is positioned in front of the spindle row with its fitting support portion 15 substantially facing the lower end of the spindle 1, and is supported by a suitable movement guide member (not shown) or the like. be done.

At the same time, the shifter rod 8 of the reciprocating drive mechanism 7 is supported under the bobbin holder 6 so as to be able to reciprocate along the longitudinal direction of the machine, and as shown in FIG. Connect by etc.

Note that at least two support levers 10 are provided for one unit of bobbin holder so that the bobbin holder 6 can move smoothly.

Although the shifter rod can be reciprocated manually, it can be moved automatically by electrical commands when the bobbin is fully loaded, and the main unloading port can be used to automatically move the shifter rod until the bobbin is fully unloaded. make it happen.

Now, when the bobbin is full, the bobbin rail 4 stops at a fixed position, as shown in FIGS. 2A and 2B, and the flyer 2 stops with its plenometer 2a in contact with the rear side of the full bobbin 3a.

Here, check the stopping position of the bobbin rail 4 and check its height so that the lower end of the spindle 1 is at the fitting support part 1 of the bobbin holder 6.
Modify it so that it faces 5.

Next, move shifter rod 8.

This causes the support shaft 12 to rotate together with the shifter arm 9.
At the same time, the support lever 10 rotates and the bobbin holder 6 moves forward toward the full bobbin 3a as shown by the arrow.

The bobbin holder 6 moves forward in an approximately straight line through engagement with the bottle through the long sliding window, and as shown in an enlarged view in FIG. position it directly below the bobbin and stop.

Next, as shown in Figure 3, attach the bobbin rail 4 to the spindle 1.
The tip of the bobbin 3 is removed from the bobbin 3, and further lowered to a position where it is completely removed from the fitting support portion 15 of the bobbin holder 6.

When the tip of the spindle 1 is pulled out from the full bobbin 3a, the full bobbin 3a descends slightly due to its own weight, and is fitted and supported upright on the bobbin support portion 15' of the fitting support portion 15.

In this case, the bobbin holder 6 may be slightly raised without waiting for the bobbin to come down, and the bobbin holder 6 may be received and held by the support portion 15'.

When the bobbin rail 4 has been lowered to the lowest position,
Move the shifter rod 8 in the opposite direction as shown in FIGS. 4A and 4B.

The shifter arm 9 and the support lever 10 cause the bobbin holder 6 to move backward in a substantially straight line toward the outside of the machine frame as shown by the arrow while holding the full bobbin 3a.

The plenosa 2a of the flyer 2 is located behind the full bobbin 3a, and since the full bobbin 3a does not rotate and separates from the flyer 2, the roving is stretched and cut between the plenosa 2a and the full bobbin 3a, and the full bobbin 3a is not rotated but separated from the flyer 2. The movement of the tube bobbin 3a is performed smoothly without any hindrance.

The full bobbin 3a is taken out from the bobbin holder 6, which holds the full bobbin 3a and is kept stationary outside the machine, and is transported to a predetermined location.

The bobbin holder 6 is almost the same as the predetermined height of the bobbin rail 4 when the bobbin is full, and it remains at rest at the same height, so it is impossible to take out the full bobbin 3a by bending down or inserting your hand between the spindles. It is performed in a very comfortable posture, either in an upright position or slightly bent over.

After taking out the full bobbin, the empty bobbin holder 6 is returned to the normal operating position shown in FIGS. 1A and 1B by slightly moving the shifter rod 8.

In the manner described above, full bobbins are taken out at the same time by moving the shifter rod.

Although the above embodiment is a case of two spindle rows,
It goes without saying that this full bobbin take-out device can be easily installed on a single-row spindle roving frame by the same means.

As explained above, the present invention provides a roving machine in which a bobbin rail is lowered to take out a full bobbin from a spindle, and in which the same number of fitting supports as the spindles are arranged at equal intervals on the side edge of a long plate. A bobbin holder with a notch formed therein is installed at the height of the stop bobbin rail when the bobbin is full and along the entire length of the machine along the front of the spindle row. The support part is fitted to the corresponding spindle at the same time, and together with it, the lower part of the bobbin is held and retreated to the outside of the machine, so when the bobbin is full, it can be attached to the bobbin rail that stops at a predetermined upper height. Since the bobbin is taken out from the bobbin holder on the outside of the machine at almost the same height, you can operate the machine without having to bend down or insert your hand into the spindle row. It is extremely easy to perform on the aisle, reducing the labor of workers and improving work efficiency.

Moreover, according to the present invention, the bobbin holder holding the full bobbin is moved forward and backward by a combination mechanism such as a shifter rod that reciprocates and an arm that rotates in relation to the shifter rod, other link mechanisms, or racks, pinions, etc. A simple reciprocating drive mechanism ensures approximate linear movement, and it can also be activated automatically when the bobbin is full, so it can be used as a device for future automatic doffing and conveyance. It is valid.
