Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a metal wire winding device that can smoothly and beautifully wind all metal wires.

(Prior art and its problems) In a conventional device of this kind, a winding drum and a carrier table are rotated on the same axis at the same rotational speed, and the metal wire wound on the winding drum is transferred onto the carrier table. There are devices that allow the winding material to be formed by dropping it, but in this case the lowest layer of winding wire is placed directly on the carrier table, so the distance between the winding drum and the carrier table is large. The more the winding wire falls, the greater the angle it makes with the horizontal plane. In other words, since the angle between the falling winding wire and the horizontal plane at the start and end of winding is different,
The outer diameter of the winding wire tends to increase toward the upper layer, which has the disadvantage that the overall shape of the winding product, that is, the packaging appearance, deteriorates.

(Means for solving the problem) However, in order to solve the above problem, the present invention rotatably supports the winding drum on the upper base frame,
A turntable that rotates in the same direction as the winding drum is installed below the turntable, and a carrier stand is installed at an eccentric position of the turntable to receive the winding wire that falls from the winding drum, and is independent of the turntable. The winding of metal wire is configured such that the cradle of the carrier pedestal is lowered as the turntable, the carrier pedestal rotates, or the number of winding wires on the pedestal increases. This is characterized by the structure of the collecting device.

(Example) An example illustrating a specific configuration of the present invention will be described.

1 is a winding drum that is pivotally supported by a shaft ₁₁ so that it can be horizontally supported on an upper base frame (not shown) _; A turntable is fixed to a matching cylindrical shaft ₂₁ , and the coaxial shaft ₂₁ is a gearbox A fixed to a truck.
The turntable 2 is rotated by rotating a worm shaft 2 _{3 which is rotatably supported on a frame of the worm shaft 2 3 and} meshes with a worm wheel 2 ₂ integrally fixed to the shaft 2 1 by a motor serving as a driving source. 3 is rotatably supported on a screw shaft 3 1 rotatably supported at an eccentric position offset from the shaft 2 ₁ of the turntable 2 by a certain distance, and is rotatably supported on the screw shaft 3 ₁ so as to rotate independently of the screw shaft 3 1 .
A carrier stand held horizontally by rollers 2 ₄ ... 2 ₄ provided above, and a take-up frame 3 ₂ serving as a carrier is mounted on the same stand.
is permanently installed. Reference numeral 4 denotes a winding wire cradle having a nut 4 ₁ in the center that engages with the threaded portion of the screw shaft 3 ₁ , and is guided to a plurality of guide shafts 3 ₃ . . . 3 ₃ planted on the carrier stand 3. It is configured to be raised and lowered by the rotation of the screw shaft ₃₁ . The screw shaft 3 ₁ is connected to a cylindrical shaft 5 fitted into the shaft 2 ₁ of the turntable 2 via gears 5 ₁ and 5 ₂ , and a chain wheel 5 ₃ fixed to the lower end of the shaft 5 is connected to the shaft 5 . It is configured to horizontally rotate by being rotated by a chain driven by a motor separate from the motor for driving the turntable. Further, the carrier stand 3 has a gear 6 1 , a gear 6 ₁ ,
6 ₂ and is configured to rotate by rotating a chain wheel 6 ₃ fixed to the lower end of the shaft 6 by a chain driven by the same motor as the motor for driving the turntable.

(Operations and Effects of the Invention) According to the above-mentioned structure of the invention, the specific usage and operation of the device according to the illustrated embodiments are explained below.
Explain the effect.

That is, at the start of the winding operation, the motor for driving the turntable is energized to rotate the worm shaft ₂₃ ,
The turntable 3 is rotated in the same direction as the winding drum 1. At this time, the chain wheel 6 ₃ is rotated by the drive of the same motor, and the rotation of the shaft 6 causes the carrier base 3 to be rotated through the screw shaft 3 ₁ through the gears 6 ₁ and 6 ₂ .
Rotate around the axis. In other words, the carrier stand 3 performs so-called planetary rotation, revolving around the axis ₂₁ and rotating on its own axis. Carrier stand 3 at the start of work
Since the pedestal 4 is in the raised position,
The winding wire wound on the winding drum 1 falls from the upper end of the winding frame ₃₂ toward the carrier table 3, and is received by a cradle 4 in the middle, on which the winding wire is stored. I will pray. The winding wire that falls from the winding drum 1 is wound onto the cradle 4 of the planetary rotating carrier pedestal 3 in a peritrochoid shape. As the height increases and the bulk becomes high, a photoelectric switch installed to monitor the upper limit position of the height detects the non-conduction state of light and turns on the contact, causing the screw shaft drive motor to switch on. Since the motor is energized, the chain wheel ₅₃ , that is, the shaft 5, is rotated by the drive of the motor.
The screw shaft ₃₁ is rotated. Since the nut 4 ₁ screwed onto the screw shaft 3 ₁ is fixed integrally with the pedestal 4 so as not to rotate, the nut 4 ₁ , that is, the pedestal ₄ is lowered by the rotation of the screw shaft 3 1 . When the pedestal 4 is lowered a certain distance and the top layer winding wire is at a position below the upper limit position, the contact of the photoelectric switch turns OFF due to the conduction of light, cutting off the power to the motor, so the screw The rotation of the shaft ₃₁ is stopped, and the lowering of the pedestal 4 is stopped. Thereafter, each time the photoelectric switch detects a non-conducting state of light, the pedestal 4 is lowered a certain distance, and when the lower surface of the pedestal 4 is lowered to the position where it touches the upper surface of the carrier pedestal 3, a control device such as a limit switch is activated. Then, the power to both drive motors is cut off, and the rotation of the turntable, carrier stand, and screw shaft is stopped, and one unit of the wound material is formed.

This rolled material is sent to the next process by driving a cart, and after removing the rolled material, the screw drive motor is reversely rotated to raise the pedestal 4 to the above-mentioned raised position, and the next process is carried out. Prepare for winding work.

Thereafter, the above operation is repeated every time the metal wire is wound up.

As described above, according to the metal wire winding device according to the present invention, the carrier stand that receives the winding wire falling from the winding drum is rotatably provided at an eccentric position of the independently rotating turntable. The winding wire is wound onto a carrier by revolving around the rotation axis of the turntable and rotating on its own axis, so the winding is formed in a perotrochoid shape, giving it a packaging shape. Not only can it be made beautiful, but it can also increase the amount of winding.Furthermore, the cradle that receives the winding wire is usually raised to a position close to the winding drum, so that the cradle that collects on the cradle can be removed. Since the winding line is lowered as the winding line increases, the angle of inclination of the winding line falling from the winding drum is constant and small from the beginning of winding to the end.
This prevents the metal wire from bouncing up due to its elasticity, allowing the winding operation to be performed in a stable state at all times, and completely eliminating unforeseen situations such as cargo collapse.

By changing the rotational speed ratio of the turntable and carrier stand, the shape of the material to be wound can be changed, and thereby the amount of winding can be adjusted. Instead of relying on a photoelectric switch, it may be automatically lowered as the turntable or carrier stage rotates.
