Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a multi-axis turret winding system for improving the quality and yield of wound products by converting the contact pressure device into a turret and eliminating imperfections in the contact pressure during the turret. It is related to the removal machine.

The first contact pressure device of the conventional multi-spindle turret winder
To explain with a diagram, in a multi-shaft turret winding machine in which four winding shafts 3a to 3d are arranged on the main body side turret 1 and the main body side turret 1 is rotationally driven by a rotational drive shaft 2, a fluid pressure cylinder is used. 4a, arm 4
b. Even in the contact device 4 consisting of the contact pressure roller 4c, the arm 4b is tilted by the expansion and contraction movement of the rod 4a' of the fluid pressure cylinder 4a, so that the contact pressure roller 4c is moved toward and away from the winding shaft 3a. There is. In the case of such a structure, the contact pressure device 4 works effectively for winding in a fixed position, but there is a drawback that the contact pressure device 4 stops working effectively when the main body side turret 1 starts to rotate.

On the other hand, as shown in FIGS. 2 and 3, there is also a configuration in which two contact pressure devices 4 are provided, and when the rotational movement of the main body side turret 1 begins, the next contact pressure device 4 is caused to touch the baton. In this case, the timing of switching the contact pressure between the two contact pressure devices 4 was very difficult, and there was a drawback that wrinkles were generated due to air entrainment.

Furthermore, Utility Model Application No. 57-49848 was proposed as an earlier application, and this "multi-spindle winding machine" was equipped with a main touch roller (same as the contact pressure device) and an auxiliary touch roller,
Since a step of switching from the main touch roller to the auxiliary touch roller at a predetermined timing is added, the entrainment of air cannot be completely prevented in this step, resulting in wrinkles in the rolled material.

The multi-spindle turret winding machine of the present invention (hereinafter referred to as the present invention) uses a rotary drive shaft 2 provided at the center of a circular main body side turret 1 having a plurality of winding shafts 3a to 3d arranged around the periphery. In a rotationally driven multi-spindle turret winding machine, there is provided, in addition to the main body side turret 1, a rotationally driven main body side turret 1 in synchronization with the rotational drive of the main body side turret 1 and in a direction opposite to the rotational direction of the main body side turret 1. 2 turrets 6 are installed,
The second turret 6 has the plurality of winding shafts 3a~
The above-mentioned drawbacks are eliminated by arranging a plurality of pressure contact devices 4, each of which is in contact with the pressure contact device 3d.

One embodiment of the present invention will be explained with reference to FIGS. 4 and 5. A multi-shaft turret winding machine (hereinafter referred to as the present invention) is a circular winding machine with a plurality of winding shafts 3a to 3d arranged around the periphery. In a multi-shaft turret winding machine that is rotatably driven by a rotary drive shaft 2 provided at the center of the main body side turret 1, apart from the main body side turret 1,
A second turret 6 is provided which is rotationally driven in synchronization with the rotational drive of the main body side turret 1 and in a direction opposite to the rotational direction of the main body side turret 1.
A plurality of pressure devices 4 are disposed on the turret 6, each of which presses the plurality of winding shafts 3a to 3d.

The contact pressure device 4 includes a fluid pressure cylinder 4a and an arm 4.
b, and one end of the arm 4b is pivotally connected to the second turret 5. The plurality of pivot points are arranged so as to be orthogonal to each other with the rotational drive shaft 6 of the second turret 5 as the center, and the rod 4a' of the hydraulic cylinder 4a is connected to the middle part of the arm 5b and is connected to the main body side. Winding shaft 3 accompanying rotational drive of turret 1
By shortening the rod 4a' in accordance with the positional change of the winding shaft 4b, the arm 4b can be rotated, and even if the position of the winding shaft 3a is changed due to the rotational drive of the turret 1 on the main body side, as shown in FIG. , following as shown in FIG.
By applying pressure to the winding shaft 3a with a pressure roller 4c and continuing to drive the rotation of the second turret 5, the new winding shaft 3b can also be pressed. As mentioned above, the present invention provides a second turret that is rotatably driven in synchronization with the rotational drive of the main body side turret and in a direction opposite to the rotational direction of the main body side turret, separately from the main body side turret.
The second turret has a structure in which a plurality of contact pressure devices each contacting a plurality of winding shafts are disposed, and one of the plurality of winding shafts is consistently operated from the beginning of winding to the end of winding. Since contact pressure is applied by two contact pressure devices, there is no need for a contact pressure switching process from the start of winding to the end of winding, and the accompanying air entrainment is prevented.
It is possible to prevent the occurrence of wrinkles on the winding shaft, resulting in practical effects such as improving the quality of the wound product and increasing the yield.
