Abstract

PURPOSE:To manufacture a spiral spring excellent in efficiency and safety by detecting the size of a long band steel, winding and cutting to a specified length, and sending out the wound steel to a sending belt while holding the belt automatically. CONSTITUTION:A coillike band steel A in a coil box 1 is sent out to a sending- in box 3 by pulling-out rolls 2. It is passed through rolls of a pulse motor 4, and a specified position of it is heated by high frequency in the coil 5, and contained in a looper box 6 in slackened state and annealed in natural state. The band steel is then passed through a length adjusting device 7, held by a fixing device 8 and inserted into a forming cutter 9. The tip is fitted to the detaining groove of an automatic take-up device 10 for sizing, and rolled in by rotation of the device 10. The steel band A under this condition is press worked 9 and cut, and the coiled band steel A is held by a packing frame. The coiled band steel (spiral spring) is rotated downward by specified angle by an automatic packing frame holding device 14, and sent out to a sending belt with the packing frame holding the spiral spring. Thus, automatic manufacturing of a spiral spring is completed.

Description

Detailed Description of the Invention The present invention automatically adjusts the length of the copper strip, cuts it to a predetermined size, winds the copper strip, and automatically wraps the rolled copper strip. The present invention relates to a method for manufacturing a rotating mainspring spring that is fed into a feeding belt by a spring, and an apparatus therefor.

Conventionally, in order to manufacture mainsprings by winding and tightening a copper strip, the copper strip is sent to a manufacturing device and the front and rear ends of the copper strip are detected respectively to determine the dimensions. During detection, the copper strip sag, making it difficult to cut the copper strip exactly to the specified dimensions, resulting in variations in dimensions. However, in order to install the colored frame in the mechanical equipment, the worker had to manually install and remove it, which required a lot of effort and effort, lacked accuracy, and was very inefficient. A bad flaw had arisen.

The present invention was developed as a result of various researches in order to solve the above-mentioned disadvantages of the conventional spiral spring manufacturing method and its device. To provide an efficient and safe automatic spiral spring manufacturing method and device for automatically holding the wound copper strip and feeding it to a feeding belt after winding it and cutting it to a predetermined length. The purpose is to The device is one that is directly used in carrying out the invention of the method for manufacturing a mainspring spring.

rotates, the number of rotations is detected by the rotation detector (10d) (10d)', and it rotates by a predetermined number of rotations.

As shown in Figures 4 and 5, the right rotation detector (10d
) detects the start of rotation, and the start is when the magnet (10f) attached to the rotating plate (IQs) comes to the location of the rotation detector (10d). Left side rotation detection ff110J
The structure is such that the number of rotations is detected and the number of rotations is read based on how many times the magnet (10f) comes to the position of the rotation detector (10cl)'. (10g) (10g)' is a bearing.

By transmitting the information to the automatic winding device αQK and controlling the rotation speed of the shaft (I Qc ) of the automatic winding device α, an accurate length dimension of the copper strip (6) can be obtained. After being rewound a predetermined number of times under the above control, the rear end of the copper strip is pressed and cut using a forming and cutting device (9).
