Description

[Detailed Description of the Invention] The present invention relates to an improvement of a bobbin fixing device for a wire twisting machine.

Conventional hanging-type delivery bobbin shafts are fixed manually using screws or other means, which requires manual work for each delivery, which has the disadvantage that setup time increases as the number of delivery bobbins increases. There is.

The present invention was developed in view of the above circumstances, and aims to provide a bobbin fixing device for a wire twisting machine that can reduce the manual work of fixing and unfixing the hanging type delivery bobbin shaft and shorten the setup time. This is the purpose.

The bobbin fixing device for a wire twisting machine of the present invention is configured by fixing each delivery bobbin shaft in a hanging manner to the groove of each of a plurality of cradles in the wire twisting machine via a fixing means, and the fixing means is connected to the delivery bobbin shaft. It is composed of a stopper pin slidably mounted in a stopper holder fixed to the cradle that closes the upper opening of the groove into which the bobbin shaft is inserted, and a piston and an air cylinder that displace and drive the stopper pin. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS The bobbin fixing device for a wire twisting machine according to the present invention will be explained below using an embodiment with reference to FIGS. 1 and 2. FIG. 1 is a schematic diagram, and FIG. 2 is a detailed diagram of section A in FIG. 1.
In the figure, 1 is a rotary joint, 2 is an air cylinder, and 3 is a stopper pin connected to a piston (not shown) of the air cylinder 2. 5 is a delivery bobbin shaft. 6 is a pipe, and 7 is a joint of the pipe 6, which is connected manually when supplying air to the air cylinder 2.

8 is a valve. The cradle 9 is fixed within the tubular wire twisting machine 11 in parallel to the longitudinal direction of the tubular wire twisting machine 11. Reference numeral 12 denotes a groove portion formed in the cradle 9 and having an opening for attaching and detaching the delivery bobbin shaft 5 above. A conductor 13 is drawn out from the delivery bobbin 14 in the direction of the arrow.

The stopper pin 3 is slidably mounted on the cradle 9 in a stopper holder 4 fixed on the cradle 9 in a direction perpendicular to the groove 12 , and the delivery bobbin shaft 5 is attached within the groove 12 of the cradle 9 .
is inserted from above in a hanging manner, and when the upper opening of the groove 12 is closed and fixed, it is held and locked in position by a spring 10, as shown in FIG.
When taking out the delivery bobbin shaft 5 from the groove 12, air is supplied to the air cylinder 2 through the valve 8, joint 7, piping 6, and rotary joint 1 installed at the center of rotation. Stopper pin 3 is spring 10
2, the upper opening of the groove 12 is opened and the lock is released.

Therefore, the delivery bobbin 14 can be freely taken out upwards. Conversely, when inserting and locking the delivery bobbin shaft 5 into the groove 12, by releasing the air from the air cylinder 2, the tension of the spring 10 causes the stopper pin 3 to pop out and close the upper opening of the groove 12. Locked.

This series of operations for opening and closing the stopper pin 3 can be performed simultaneously at multiple locations by supplying and discharging air from the air cylinders 2 installed in each cradle 9 through a single air pipe 6, as shown in FIG. be able to.

In this way, the bobbin fixing device of the wire twisting machine of this embodiment locks the hanging-type delivery bobbin shaft 5 by holding the stopper pin fixed to the piston of the air cylinder in the locked position by the tension of the spring, and at the same time releasing the lock. In this case, air is supplied to the air cylinder and the stopper pin is moved back against the tension of the spring, so the valve can be opened and closed simply by opening and closing the valve.Moreover, since multiple valves can be opened and closed at the same time, there is almost no manual work required. This can be eliminated and the setup time can be significantly reduced.

In the above embodiment, the connection of the joint 7 and the opening and closing of the valve 8 are manually operated, but if a rotary type joint is provided in the machine body, the manual connection can be omitted. Although the work does not require much effort, manual work can be further simplified by using electric or electromagnetic valves.

As described above, the bobbin fixing device for a wire twisting machine of the present invention has the effect of significantly reducing the manual work involved in fixing and unfixing the hanging-type delivery bobbin shaft and shortening the setup time.

Claims (1)

[Claims for Utility Model Registration] 1. In the grooves of each of the plurality of cradles in the stranding machine,
Each delivery bobbin shaft is fixed via a fixing means in a hanging manner, and the fixing means is slidable in a stopper holder fixed to the cradle that closes an upper opening of the groove into which the delivery bobbin shaft is inserted. 1. A bobbin fixing device for a wire twisting machine, comprising a stopper pin attached to a wire stranding machine, and a piston and an air cylinder for displacing and driving the stopper pin. 2. The stopper pin is locked at the upper part of the groove through the spring to prevent the delivery bobbin shaft from coming off, and air is supplied to the cylinder to resist the tension of the spring through the piston and move the stopper pin to the upper part of the groove. A bobbin fixing device for a wire twisting machine according to claim 1, which is formed so that the lock is released when the bobbin is removed from the bobbin.
