Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a bobbin support device for supporting a bobbin in a roving frame in which a flyer having a guide leg in the center is supported by an upper fixed rail.

As shown in FIGS. 6 to 9, in the conventional device, a pair of engagement grooves 22 are bored in the lower part of the bobbin 15, and a bobbin protruding guide portion 10 and a pair of protruding piers 21, 21 are provided in the bobbin wheel 6. is formed, and the operator has to remove the bobbin 15.
The bobbin 15 was inserted into the protruding guide part 10 so that the protruding pins 21 and 21 were engaged with the engaging grooves 22 and 22 of the bobbin, and the bobbin 15 was placed on the bobbin wheel 6.

The driving force of the bobbin wheel 6 is the protruding pins 21, 21.
and is transmitted to the bobbin 15 via the engagement grooves 22, 22.

However, in such a conventional device, the retaining groove 22.2
Since the protruding vinyl/21.21 is required to be engaged with the saccel work, it is a major obstacle in terms of work speed and automation of bobbin exchange.Especially when the bobbin itself has become larger due to the large package, the bobbin itself has become larger. The bobbin loading work carried out by the above involves heavy labor, and it is also a very complicated work since the protruding pins 21 and 21 must be reliably engaged with the engaging grooves 22, 22.

Therefore, an automatic device is desired, but the protruding pin 2
1 and 21 and the engagement grooves 22 and 22 requires a very complicated working mechanism, which is not practical.

Furthermore, if the engaging groove 22.22 and the protruding pin 21.21 are not engaged as shown in FIG. 9 due to an operator's work error, the bobbin 15 will tilt, and in this state the bobbin rail will rise. For example, the bobbin/15 and the guide leg of the flyer come into sharp contact, resulting in damage to the bobbin or the flyer.

The purpose of the present invention is to provide a bobbin support device that eliminates the complexity of the bobbin loading work of conventional devices and allows for easy automatic loading. Even if the groove and the protruding pin are not engaged, the bobbin remains upright, and the engaging groove and the protruding pin can be automatically engaged in the process up to the start of operation.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

In the figure, 1 is a flyer supported by an upper fixed rail 2 and driven to rotate, and 3 is a guide leg having a shape e in the center of the flyer 1.

4 is a bobbin rail that moves up and down, and a bobbin wheel 6 that supports the bobbin 5 and a power transmission means (drive shaft 7, gears 8, 9) for rotating the bobbin wheel 6 are installed inside the rail.

Reference numeral 10 denotes a bobbin protruding guide portion formed to protrude from the bobbin wheel 6, which is aligned with the guide leg 3 and can be fitted relatively tightly into the bottom hole of the bobbin.

Reference numeral 11 designates four protruding pins Ifi, which are equally spaced around the guide portion 100 of the bobbin wheel 6, and each pin 11 has the same height, but is formed lower than the guide portion 10.

Reference numeral 12 denotes engagement grooves drilled around the bottom hole of the bobbin 5 so that the protruding pins 11 can be engaged therein, and eight engagement grooves, which is twice the number of protruding pins, are provided at equal intervals.

This means that the engaging grooves 12 are provided at equal intervals so that there are two combinations of the protruding bits 11 and the corresponding intervals.

In such a configuration, the bobbin 5 only needs to be inserted into the guide portion 10 of the bobbin wheel 6 and positioned by the operator or an automatic tube changer, and the protruding pin 11 and the engagement groove 12 do not necessarily have to be stopped. Even if it is not in the stand state, the four protruding piers 11 are aligned with the guide part 10 as shown in FIG.
The top of the bobbin 5 supports the bottom surface 5a of the bobbin 5 in an upright state.

That is, in order to maintain the upright state, it is first necessary to align the center positions of the bobbin 5 and the bobbin wheel 6. For this purpose, the protruding guide part 10 is positioned higher than the protruding pin 11, and the bobbin 5 is aligned with the guide part 10. Since the protruding pins 11 that can contact the lower end of the bobbin are provided at equal intervals around the protruding guide part 10, the bobbin wheel rotates 60 times. Even if the bobbin is fed uniformly regardless of the stop position in the direction, the bobbin is received by the protruding pin 11 and maintained in an upright state.

When the bobbin rail 4 is raised from this state in order to wind the roving around the bobbin 5, the bobbin 5 is positioned by the protruding guide part 10, so the guide leg 3 can be inserted into the upper end without any trouble, and then the bobbin wheel 6 and Flyer 1
When the lever starts to rotate, the friction between the upper end of the bobbin 5 and the guide leg 3, and the weight of the bobbin 5 cause relative movement between the bobbin and the bobbin wheel 6, and the engagement groove 12 and the protruding pin 11 automatically move. The vehicle becomes stationary.

The above-mentioned automatic engagement is carried out smoothly because the bobbin 5 itself has become heavier due to recent large packaging, and because the bobbin wheel 6 rotates rapidly due to increased speed.

Moreover, since the flyer 1 is equipped with a guide leg 3 for supporting the bobbin, the bobbin wheel 6 does not need to be manufactured with consideration given to maintaining the posture of the bobbin during operation, and has a role of positioning the bobbin and transmitting rotation. Therefore, the amount of protrusion of the guide portion 10 only needs to be small, and the protrusion pin 11 that is lower than that is extremely low.

The protruding pin 11 can also be manufactured by considering only the rotational transmission force without considering the posture maintenance of the bobbin 5.
Very low protrusion pi/11 combined with increased bobbin weight
becomes.

From this point of view, even if the bobbin 5 is not engaged with the protruding pin 11 and stands upright, the bobbin wheel 6 will rotate afterwards and the engagement groove 12 will engage with the protruding pin 11. In this case, the bobbin head is very small and does not pose any problem for subsequent operation.

Therefore, the bobbin 5 can be uniformly supplied to the bobbin wheel 6 regardless of the stopping position in the rotational direction of the bobbin wheel 60, which greatly encourages the adoption of a simple automatic tube changer.

In this embodiment, four protruding pins 11 are used, but three or more protruding pins 11 may be used. The more the protrusion pin 11 and the engagement groove 12 engage, the less the relative movement between the bobbin and the bobbin wheel 6 is required, and the more the transmission force from the protrusion pin 11 applied to each engagement groove 12 is dispersed. Therefore, damage to the engagement groove 12 can be reduced.

As described above, in the device of the present invention, the flyer having the guide leg 3 for supporting the bobbin in the center is supported on the upper fixed rail 2, while the bottom of the bobbin is relatively attached to the protruding guide portion 10 of the bobbin wheel 6 on the bobbin rail. When the bobbin wheel 6 is inserted in a tight fit, the protruding pin 11 of the bobbin wheel 6 engages with the retaining groove 12 formed at the bottom of the bobbin to transmit the rotation of the bobbin wheel 6 to the bobbin, and the bobbin rail is raised after loading the bobbin. In the roving machine, in which the guide leg 3 is inserted into the tip of the bobbin, three or more of the protruding pins 11 are provided at equal intervals around the guide portion 100, and
The retaining grooves 12 of the bobbin are shaped lower than the guide part 10 with the same height, and the retaining grooves 12 of the bobbin are arranged at intervals corresponding to the protruding pins 11, and the combination of these intervals is one or more. This is a bobbin support device for a roving frame machine, which is characterized in that the bobbin bottom holes are provided at equal intervals around the bottom hole of the bobbin. Even without the bobbin 5, the bobbin 5 is supported in an upright state, and the guide leg 3 can be reliably inserted into the upper end of the bobbin 5 without damaging the bobbin 5 or the flyer 1 even if the bobbin rail 4 is raised.

Furthermore, when the operator attaches the bobbin 5 to the guide section 10,
Since it is not necessary to engage the engaging groove 12 and the protruding pin 11, the working efficiency can be greatly improved and it is also possible to use an automatic tube changer.
