Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] Industrial Field of Application The present invention relates to an automatic hook button attachment tape manufacturing machine.

Conventional technology In the past, the patent application for the applicant's patent was published.
No. 47-23733 (tape tensioning device for tape manufacturing machine with snap button) existed.

The shoulder snap manufactured by this device was developed exclusively to prevent brassiere straps from slipping off the shoulder. As of today, it has come to be used as a shoulder snap for fixing shoulder parts, and the length of the tape, the spacing of the snap buttons,
That is, the mounting distances between female and female, male and male, or male and female have become diverse.

However, in the conventional invention, it is not possible to adjust the pitch interval of the hook button, and a feed die is required for each hit size, and the feed die must be replaced each time. In addition, pitch adjustment requires replacing the drum for feeding and cutting, which takes time and effort. In addition, since the drum rotates continuously and rotates regardless of whether or not a hook button is attached to the tape, there is a risk that tape to which no hook button is attached will also be sent out and cut, resulting in defective products. Furthermore, two machines were required: an upper die driving machine for female and a lower die driving machine for male.

Problems to be Solved by the Invention The problem to be solved by the present invention is that, in addition to the above-mentioned conventional drawbacks, when used as shoulder pads, it is necessary to change the spacing between the hook buttons and the length of the tape depending on the design of the garment. The tape and feeding length, that is, the cutting length of the tape, can be adjusted and cut to a desired length, and the hook buttons attached to both ends can be fixed at the same time, and the pitch of the hook buttons can be freely adjusted to the desired spacing. To provide an automatic hook button attachment tape manufacturing machine capable of producing hook button attachment tapes with male and male, female and female, and male and female snap buttons attached using one machine.

[Structure of the invention]

Means for Solving the Problems The means of the present invention comprises a hook button attaching device and a tape feeding and cutting device. is equipped with a mechanism that can adjust the spacing between the other upper and lower chucks, and detects the presence of a hook button during the feeding path of the tape in which the button is driven at the required spacing by the upper and lower chuck, and when there is no button attached to the tape. A sensor was installed to stop the machine.

Embodiment As shown in FIG. 1, the present invention consists of a hook button attaching device A and a tape feeding and cutting device B.

In the hook button attaching device A, a continuous body in which a large number of pairs of hook buttons H, H are attached continuously at regular intervals to a continuous long tape t is sent to the tape feeding and cutting device B, where the pair of hook buttons are attached.

Operation The operating state of the present invention will be explained with reference to Fig. 11. At the start, the tape is set and the power is turned on.
Make it. Next, turn on the foot switch 101,
Turn on the start switch 102. As a result, the operation is started and the tape feed motor 56 is started.
ON, the second detection sensor 35' starts counting, and this signal is sent to the controller 103 (if the hook button is not attached to the tape, there is no signal from the sensor and the tape feed motor is stopped by the timer)
A signal is sent to the solenoid block 104, and the first solenoid 46 operates to close the sliding body 47 (45 and 1).
body), and the first detection sensor 35 is on standby.
That is, the operator waits for the upper and lower chucks of the lock button attachment device A to advance the hole button that has been driven into the tape. Then, a hot button is detected and a signal is sent to the controller 103. A signal from the controller 103 stops the tape feed motor, operates the second solenoid 105 as shown in the figure, and disengages the clutch (not shown). This second solenoid 105 operates only for a very short time (about 0.2 seconds). That is, the hook button is driven in by the upper and lower chucks 4, 5, 4', and 5', and the tape is heat-cut. Furthermore, the second solenoid and the first solenoid are restored by a signal from the controller 103, and the second detection sensor 3
5' is reset. Then controller 10
Send the start signal to the tape feed motor from step 3, turn the tape feed motor ON again, and repeat the above operation.
