Abstract

PURPOSE:To improve the efficiency of many kinds of take-up work by blocking the optical path of a photoelectric sensor by a second arm to make the center of a core diameter coincide with the center of a core chuck. CONSTITUTION:A first arm 3 is tilted by the contact with the outer diameter of a core fed to a vertically moving V-shape core bearer 1, and the inclination of a second arm 4 moved integrally with the first arm 3 makes the screening position of a photoelectric sensor 6 by the downward movement of the V-shape core bearer 1. This difference of the screening position makes the core chuck center of a full automatic take-up machine coincide automatically with the center of each core supplied to a core chuck even if the diameters of cores are diverse. The efficiency of many kinds of take-up work is thereby improved.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a core diameter detecting centering device for automatically aligning the center of a core chuck of a fully automatic winder with the center of the core diameter supplied to the core chuck. Is.

[0002]

2. Description of the Related Art Conventionally, there have been various automatic core feeders for automatically supplying a core having a fixed diameter to a fully automatic winder. However, the production of many types of rods and short cycles has increased, and the number of core types has increased significantly, and the core diameter is automatically detected and the core is placed at the center of the core chuck of the fully automatic winder. There has been a great demand for a centering device for detecting the core diameter that automatically matches the centers.

[0003]

The problem to be solved is to solve the problems of the core chuck center of the fully automatic winding machine and the core supplied to the core chuck even if the cores have different diameters. It is to match the center automatically.

DISCLOSURE OF THE INVENTION The present invention is a V which moves up and down.
The first arm is tilted by contact with the outer diameter of the winding core supplied to the V-shaped winding core cradle, and the tilt angle of the second arm that moves integrally with the first arm is V-shaped winding. By the downward movement of the wick, the shielding position of the photoelectric sensor is determined. Even if the shielding positions are different for the cores having different diameters, it is easy to automatically match the center of the core chuck of the fully automatic winder with the center of the core supplied to the core chuck. We have realized a core diameter detection centering device with various mechanisms.

FIG. 1 is a side view of an embodiment of the device of the present invention, in which reference numeral 1 is a V-shaped core cradle, and a core is placed on the upper surface of the core cradle 1. Reference numeral 2 denotes a fixing member, and the fixing member 2 fixes the core receiving base 1. 3 is a first arm,
One of the arms 3 is rotatably attached to the fixing member 2,
When the outer diameter of the winding core comes into contact with the other side of the first arm 3, the first arm 3 tilts, and when the winding core is completely placed on the winding core cradle 1, the first arm 3 stops at a predetermined tilt angle. To do. Four
Is a second arm, and the second arm 4 is connected to the first arm 3 by mechanical force transmission means described later. Reference numeral 5 is a mechanical force transmitting means, and the mechanical force transmitting means 5 includes, for example, a mechanical force transmitting means by meshing gears with each other, a transmitting means by a combination of a chain and a sprocket rocket, and the like. In short, the rotational force of the first arm 3 is transmitted to the second arm 4,
Any means that tilts the second arm 4 may be used. 6 is a photoelectric sensor, and the photoelectric sensor 6 is the second arm 4
A control signal for stopping the driving means (not shown) for moving the core receiving base 1 up and down is obtained by being cut off by.

FIG. 2 is a sectional view of the main part of FIG.
2, 3, 4, and 5 are the same symbols as in FIG. Reference numeral 2A denotes an upper plate member of the fixing member 2, and the upper plate member 2A is fixed to one side of the V-shaped winding core cradle 1. 2B and 2B are side wall members, and the side wall member 2B is fixed to the upper plate member 2A at a predetermined interval. Holes are formed in the side wall member 2B at predetermined intervals in the vertical direction.

The case where a gear mechanism is used as the mechanical force transmitting means 5 for connecting the second arm 4 and the first arm 3 will be described.

Reference numerals 5A and 5B are two shafts, which are respectively penetrated and supported by holes formed in the side wall member 2B at predetermined intervals in the vertical direction. 5C and 5D are first spur gears, and the first spur gears 5C and 5D are fixed together with the first arm 3 to one of the two shafts (hereinafter referred to as the first shaft 5A). There is. 5E and 5F are second spur gears, and the second spur gears 5E and 5F are fixed together with the second arm 4 on one of the two shafts (hereinafter referred to as the second shaft 5B). There is. The second spur gears 5E and 5F have a smaller diameter than the first spur gears 5C and 5D and mesh with the first spur gears 5C and 5D. The first shaft 5A is the second shaft 5
It is longer than B.

FIG. 3 is a side view of FIG. 2, and the same symbols used in FIGS. 1 and 2 indicate the same things.

Reference numeral 7 denotes a bracket, which has an L-shaped upper-case letter and has an L-shaped long side portion 7A fixed to the lower surface of the upper plate member 2A. A pressing member 8 is fixed to one end of the first shaft 5A. Reference numeral 9 denotes a bolt, which is screwed to the L-shaped short side portion 7B so that the lower end of the bolt 9 contacts the upper surface of the pressing member 8. Reference numeral 10 denotes a spring. The spring 10 is arranged at a position where the center line of the bolt 9 and the center line of the spring 10 coincide with each other, and the pressing member 8 tilts downward as the first arm 3 tilts. When the spring 10 is pressed and the tilting movement of the first arm 3 is released, the restoring force of the spring 10 causes the first arm 3 to return to its original position.

[0011]

As described above, according to the present invention, since it is not necessary to measure the core diameter one by one by the hand of the operator, and moreover, it is not necessary to manually perform the center alignment, and therefore the efficiency of the winding work of various kinds is improved. The tilt of the second arm interlocking with the first arm due to the contact with the outer diameter of the winding core further increases the shielding position of the photoelectric sensor, and thus the winding core of the fully automatic winder. Since the center of the chuck and the center of the diameter of the core to be supplied to the core chuck are automatically matched, it can be realized with a simple structure without any special installation of a drive source required for centering.
