Description

[Detailed description of the invention] The present invention relates to an automatic mainspring spring wrapper holding device that automatically holds a wrapper surrounding a roll-formed steel strip (spring spring) and sends it to a feeding belt. be.

Conventionally, in automatic mainspring spring manufacturing equipment, in order to wrap a steel strip (mainspring spring) that has been cut into a fixed size and rolled into a C-shaped wrapping frame and feed it to a feeding belt, the wrapping frame must be manually held. After holding it in place and setting it in place, the mainspring was wrapped around it, and the wrapping frame was held in the hand again and placed on the feed belt, but in this working condition, the speed was extremely slow and the work efficiency was reduced. Moreover, since the work was carried out by hand, there were drawbacks such as a danger if the mainspring spring came off from the casing.

In view of the above-mentioned drawbacks of the conventional art, the present invention has developed an efficient mainspring spring package that can perform the above-mentioned work automatically with a machine, does not require human labor, speeds up the manufacturing process, and is highly safe. The purpose is to provide an automatic frame holding device.

An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 shows the configuration of the main parts of the packaging frame gripping part, including the arm part 2 that holds the packaging frame 1, the complete holding detection part 3, the support frame wall 4, the slide frame body 5 and the arm part 2. The cylinder part 6 that advances and retreats, the base 7 and the base 7
It consists of a rotating cylinder 8 that rotates 1/4 turn.
The arm part 2 opens and closes using air pressure to grip and release the packaging frame 1. When the packaging frame 1 is completely held by the arm part 2, the outer surface of the center curved part of the packaging frame 1 is Only when it comes into contact with the complete holding detection part 3 does the rotary cylinder 8 operate and the whole body rotates.

Next, the steps of an automatic mainspring spring manufacturing apparatus in which the automatic mainspring spring encasement retaining apparatus of the present invention is used will be schematically explained with reference to FIG. The steel strip A stored in a coiled state in a coil box 101 is fed into a feeding box 103 by a pull-out roller 102, and further passed through a feeding pulse motor 104, where a predetermined portion is heated in a coil 105 of an induction annealing device. It passes through a looper box 106, is annealed in its natural state, passes through a length adjustment device 107, is held by a fixture 108, is inserted into a shaping/cutting device 109, and is inserted into an automatic dimension winding device 110. Caught up in the shaft. The rolled and formed steel strip A is automatically shaped and cut at the end by a cutting device 10.
It is pressed and cut at step 9. At this time, the wound steel strip A is held within the wrapping frame 1 which is advanced by the cylinder 6.

To explain the operating state of the automatic mainframe spring retaining device of the present invention installed in the following positions in the above configuration, first, as shown in FIGS. 2 and 3, the empty envelope 1 has a cylindrical shape. The empty packaging materials 1 are stacked one after another by hand on the pillars 9 of the
is guided forward (to the left in the figure) by the guide plate 11, and the tip of the wrapping frame 1 is caught in the recess 12a of the contact plate 12. After that, the guide plate 11 is guided backward by the cylinder 10. be taken back to Next, lower cylinder 1
3 moves to the right in the figure and pulls the support 14, the wrapping frame 1 rotates 1/4 and becomes suspended from the cover plate 12. In this state, as shown in FIGS. 4 and 5, the cylinder 15 at the bottom of the machine operates upward, the contact plate 12 pushes the packaging frame 1 upward, and the arm 2, which had been waiting in advance, moves upward. Grasp the envelope body 1 and turn the base 7 by 1/4 turn with the rotating cylinder 8, as shown in Fig. 6, to form a rolled steel strip (spring spring).
embrace. Furthermore, the wrapping frame gripping part is rotated approximately 60 degrees downward by the rotating cylinder 8 while holding the steel strip (spring spring), and the wrapping frame 1 is now holding the steel strip (spring spring). By opening the arm 2, the wrapping frame 1 is thrown onto a feed belt (not shown), and the working process is completed.

That is, the empty wrapping frame 1 is moved from the support 9 to the guide plate 11.
By operating the cylinder 13, the support of the support plate 14 is removed, and the plate 12 is suspended from the plate 12, and the plate 12 rises in the suspended state. rises with
After reaching the arm part 2 and being held by the arm part 2, the wrapping frame gripping part is further rotated 1/4 turn to keep it horizontal, and after the steel strip (spring spring) is wrapped around the wrapping frame 1, the next time. When the frame gripping part is rotated approximately 60 degrees downward, arm part 2
The wrapper frame 1 is thrown onto the belt by opening it.

Since the present invention has the above-mentioned configuration and action, the wrapping frame 1 is held by the arm portion 2, and this holding state is detected by the complete holding detection unit 3 to detect whether or not the wrapping frame 1 is securely gripped. Since we have confirmed this, it is safe that the packaging frame 1 will not come off, and the packaging frame 1 stacked on the support 9 will be automatically guided to move and held in the arm 2, and then the packaging frame 1 will be After holding the mainspring spring, it rotates and feeds it to the feed belt, so the work can be done completely automatically without the need for manpower, improving work efficiency and increasing manufacturing speed, thereby providing inexpensive mainspring springs. The purpose of the present invention is to provide an automatic mainspring spring enveloping frame body holding device that has great effects.
