(Prior Art) An interlining tape for clothing is provided between the front and back of a garment in order to shape the garment and prevent the garment from losing its shape. This clothing interlining tape, especially the adhesive core tape, is used at different locations depending on the type of clothing,
The length of the tape is not constant. Therefore, conventionally, an operator puts his / her own amount of adhesive core tape on a place of use of clothes, heats it with an iron to bond it, and then cuts and removes an unnecessary part of the tape.

(Problems to be Solved by the Invention) However, according to such a work process, there is a problem that not only the product varies due to the skill of the worker, but also the use efficiency of the adhesive core tape decreases.
Further, since it depends on the skill of the worker, it is difficult to improve the work efficiency of such a bonding work.

Furthermore, a cutting device (for example, Jitsukai Sho 60-87696), which cuts the interlining tape for clothing to a preset length and produces a large amount of tape of a certain length, has been conventionally known. However, this type of cutting device
Only tapes of a predetermined length, such as tapes, are continuously mass-produced, and it is not possible to adapt to the work that repeatedly requires adhesive core tapes of different lengths in the above-described predetermined order.

The present invention has been made in view of the above circumstances,
Its purpose is to be able to repeatedly cut tape such as clothing interlining tape in a predetermined order into several preset lengths according to the use place, and the progress of the bonding work, that is, the work of the worker. An object of the present invention is to provide a tape feeding / cutting machine capable of feeding / cutting a tape according to the speed.

(Means for Solving the Problems) In order to solve the above problems, the means adopted by the present invention is to drive a tape (2) driven by a sending signal and having a length corresponding to the sending signal. A feeding mechanism (5) for cutting, a cutting mechanism (40) for cutting the fed tape (2) by crossing in the tape feeding direction by a cutting signal, and holding the cut end of the cut tape (2). A standby mechanism (50) for waiting and a touch sensor (49 provided near the standby mechanism (50) for generating a removal signal when an operator touches the tape (2) on standby immediately after removing it. ), Several kinds of sending signals and sending signal setting means for setting sending order thereof, and a removal signal from the touch sensor (49) to judge that the previous tape (2) has been removed, The next test set in the mechanism (10). A tape sending / cutting machine (300), comprising: a calculating means for sending a cutting signal to the cutting mechanism (40) after a sending signal corresponding to the loop sending length is inputted.

Is the gist.

(Operation of the Invention) Therefore, the tape feeding / cutting machine (300) according to the present invention sets the length of the tape (2) such as the interlining tape for clothing in advance to several kinds by the above-mentioned means according to the place of use. While the bonding work of the previous tape (2) is being performed, the tape (2) of the length corresponding to the next work place is sent out and cut off and made to stand by, and the bonding work of the previous tape (2) is completed. Then, when the operator removes the next tape (2) on standby, the next tape (2) is further sent out and cut to a length corresponding to the set value and made to stand by to prepare for the next adhesive work. In addition, the operation of sequentially sending and cutting a tape (2) such as an interlining tape for clothing to a preset number of lengths and making it stand by is repeated. Immediately after removing (2), near the standby mechanism (50) By touching the broken touch sensor (49), it is possible to detect quickly and surely that the tape (2) has been removed, and to adjust the feeding and cutting operation of the next tape (2) to the working speed of the operator.

It functions to send a cutting signal to the cutting motor (47) and to send a pulse train as a driving sending signal to the pulse motor (20) of the sending mechanism (5).

Next, a method of using the tape feeding and cutting machine (300) according to the present embodiment configured as described above will be described with reference to FIGS. 3 to 6 and 9.
It will be described with reference to FIGS.

First, the loading operation will be described with reference to FIG. Turn on the power switch and clear all the displays on the operation panel (210) (STEP301). The operator rolls the tape (6
2) Fit the feed roller (61) and feed frame (6
After mounting the tape (2) on the tape (2), pull out the end of the tape (2) and feed it between the drive roller (10) and the driven roller (30) and the tape feed through each tape guide (71) (72) (75). Insert the tape (2) in the order of the outlet (43a).

Next, after the operator presses the automatic / manual switch (215a) of the control device (200) to switch to manual (STEP302) and then presses the manual feed switch (215b), the manual feed switch (215b) is pressed. Only the pulse motor (20) is supplied with a pulse train as a transmission signal, and the pulse motor (2
0) rotates and the tape (2) is delivered. After that, when the manual cutting switch (215c) is pressed (STEP303) when the tape (2) of an appropriate length is sent, a cutting signal is sent to the cutting motor (47), and the cutting motor (47) is rotated. Then, the tape (2) is cut. At this time, the upper blade (44) is stopped in a state of descending downward, and accordingly, the tape holding plate (53) of the standby mechanism (50) holds the cut end portion of the cut tape (2). Therefore, the worker pulls out the cut tape (2) and removes it (STEP 304). By the above operation, the loading operation of the tape (2) is completed.

Next, the delivery cut length of the tape (2) is set. The operation is performed by the operator as shown in FIG.
It starts by pressing the setting switch (211) of 0) (STEP305 in FIG. 9 and STEP305 in FIG. 10). Setting switch (211)
After pressing, the first process switch (212a) is pressed to input the tape feed length to be cut in the first process in decimal units in millimeters (STEP 306). This operation is performed by operating the ten keys (213) on the operation panel (210). (STEP307) is a correction step, in which the input number is corrected and the tape feed length is set to a desired number. When this work is completed, the memory switch (215
When d) is pressed (STEP 308), the tape sending length data of the first step is stored in the nonvolatile RAM (223), and the setting of the tape sending length of the first step is completed (STEP 309). Then, (STEP30
Returning to step 5), press the process switches (212a to 212e) of the second to fifth processes and press the numeric keypad (21
Enter the tape feed length to be cut in each step by 3),
By pressing the memory switch (215d), the second process to the fifth process
The tape feed length of the process can be set. Of course,
It is not necessary to set all of the first step to the fifth step,
If necessary, the setting of each step may be omitted, and in this case, the tape feeding / cutting operation of the omitted step is not performed. After the setting of each tape sending length is completed, the operator pushes the setting switch (211) again to complete the setting operation of the tape sending length.

Next, in FIG. 11, when the operation for setting the tape feed length is completed and the operator presses the automatic / manual switch (215a) to switch the mode to automatic, when the process start switch (215f) is pressed,
The tape feeding / cutting device (100) starts the automatic feeding / cutting operation of the tape (2) (STEP310). This operation will be described below in the case where only the tape feeding length in the first step and the second step is set. This also operates in the same manner when the tape feed length of the first step to the fifth step is set.

Non-volatile when the operator presses the process start switch (215f)
The pulse train corresponding to the tape sending data of the first process stored in the RAM (223) is input to the pulse motor (20) according to the instruction of the CPU (221), and the pulse motor is driven by the number corresponding to the number of pulse trains. (20) rotates and the tape (2) of the set length is delivered by the cooperation of the driving roller (10) and the driven roller (30) (STEP310). When the tape (2) is sent out, a cutting signal is sent to the cutting motor (47) by an instruction of the CPU (221), the cutting motor (47) rotates, the upper blade (44) descends, and the lower blade (45). Cut the tape (2) in cooperation with (STEP320). At this time, when the lowered upper blade (44) comes to the bottom, the blade up / down lever (4
The detection piece (48a) of 8) pushes the cantilever (82) of the lower limit switch (81) and sends a stop signal to the CPU (221).
The CPU (221) interrupts the cutting signal to the cutting motor (47) to stop the sliding of the upper blade (44). At this time,
The holding plate of the standby mechanism (50) lowered together with the upper blade (44) presses the cut end of the cut tape (2) against the guide plate (41), and the cut tape (2) is clamped. Standing by to hang down from the tape sending and cutting device (100) in the closed state (STEP330).

Next, the operator touches the touch sensor (49) immediately after pulling off the tape (2) on standby, and heats and adheres the tape (2) to a predetermined portion of the clothes with an iron. During this work, tape feeding and cutting device (100)
Works as follows. That is, the worker uses the tape (2)
When the touch sensor (49) is touched immediately after removing (STEP340), the removal signal is sent to the CPU (221),
(221) determines that the cut tape (2) has been removed, and sends a cutting signal to the cutting motor (47), and the cutting motor (47) starts rotating and raises the upper blade (44). When the upper blade (44) rises and reaches the uppermost position, the detection piece (48a) of the blade up / down lever (48) pushes the cantilever (82) of the upper limit switch (80) to stop signal as described above. To the CPU (221), and the CPU (221) cuts off the disconnection signal to stop the upper blade (44) at the uppermost position. When the upper blade (44) stops, the sending signals in the next order are input to the sending mechanism (5), the process returns to (STEP310), and the CPU (221) is a nonvolatile RAM.
The pulse train corresponding to the tape sending data of the second process stored in (223) is thrown into the pulse motor (20), and the minute pulse motor (20) corresponding to the number of the pulse trains.
Is rotated and the tape (2) of the set length is delivered.
When the tape (2) of the second step is sent out, the same as above.
The tape (2) is cut by the instruction of the CPU (221), and at the same time, the cut tape (2) is held by the tape pressing plate (53) and the guide plate (41) so as to hang down. . Here, when the sending and cutting work in the second step is completed, the counter counts the number of cycles with the operation up to that point as one cycle, and the value is counted on the operation panel (21
It is displayed on the display block (214) of (0) so that the worker can monitor what cycle the work is currently performed (STEP322). Now, in order to carry out the tape adhering work in the second step, the tape (2) on which the worker stands by
When the touch sensor (49) is touched immediately after the removal, the upper blade (44) rises and stops at the uppermost position, and the tape feeding / cutting operation of the first step is started again.

As described above, the tape delivery / cutting machine (300) according to the present embodiment is capable of delivering the tape of the first step → cutting → standby → delivering the tape of the second step → cutting → standby → the tape of the first step. The operation of cutting the tape (2) of the set length in the set order and making it stand by is repeated, such as sending out → cutting → waiting.

Further, since the touch sensor (49) is fixed near the standby mechanism (50), that is, on the front surface of the guide plate (41) of the cutting mechanism (40), the operator removes the tape (2). Immediately after touching, the touch sensor (49) can be easily touched, and unlike other switches, the touch sensor (49) outputs a detection signal just by touching it, so that the tape (2) can be quickly and reliably touched. It can be detected that the tape has been removed, and therefore, the next sending and cutting operation of the tape (2) can be reliably performed.

By the way, the scope of the present invention is not limited to the configuration of this embodiment.

For example, in this embodiment, the position of the upper blade (44) is detected by the limit switches (80) (81) via the detection piece (48a) of the blade up-down lever (48), but the optical sensor is Alternatively, the position of the upper blade (44) may be directly detected.

Further, it goes without saying that the touch sensor (49) is not limited to the pressure switch (49) as in the above-mentioned embodiment, and it is needless to say that it may be another sensor, for example, a capacitance sensor (49) or the like. Is.

In the above description, the interlining tape (2) for clothing is taken as an example, but the present invention is not limited to this, and tapes in other fields such as industrial tapes and masking tapes ( It goes without saying that it can also be used for 2).

(Effects of the Invention) As described above, the tape feeding / cutting machine according to the present invention sequentially feeds and cuts the tape such as the interlining tape for clothing into several preset lengths according to the place of use and makes them stand by. The above operation is repeated.

Therefore, by adhering the interlining tape for clothes and the like using this tape feeding and cutting machine, it is possible to make the products uniform, improve the efficiency of use of the tape, and improve the efficiency of the adhering work.

Furthermore, since the touch sensor is fixed near the standby mechanism, it is easy for the worker to touch the touch sensor immediately after removing the tape, and the touch sensor is different from other switches, and touches. Since the detection signal is output only by itself, it is possible to detect quickly and reliably that the previous tape has been removed.

Therefore, the tape can be fed and cut according to the progress of the bonding work, that is, the working speed of the worker.
