装置を低速から高速に切り替えている。BACKGROUND TECHNOLOGY Conventionally, as seen in Japanese Utility Model Publication No. 52-12657, bag making machines of this type have been known to allow the original fabric fed in by a roll device for feeding the original fabric to drop down once and transfer it to a roll device for intermittent transfer of the original fabric. and is configured to perform welding and shearing during intermittent stops. In this configuration, the roll device for intermittent transport of the original fabric feeds the original fabric forward by a predetermined length at a time by intermittent transfer, but the roll device for feeding the original fabric obtains a good unwinding action of the original fabric. The machine operates continuously for this reason, and feeds the raw material forward continuously. Therefore, the lower end of the web suspended between both roll devices moves up and down in response to the operation of the roll device for intermittent transport of the web. In this case, when the feed speed of the roll device for intermittent transfer of the material is high, the above-mentioned sagging gradually decreases, and as a result, the material tensioned between the two roll devices may be torn off.
Or it may be stretched. In order to solve this problem, the feeding speed of the roll device for feeding the original fabric is increased somewhat, but this gradually increases the amount of sagging of the original fabric. Therefore, in the past, a speed change means was provided to switch the rotational speed of the roll device for feeding the original fabric into two stages, high and low, and a limit switch or the like was used to detect when the amount of sagging exceeded a certain amount, and the speed change means based on the detection signal. , the feeding speed of the roll device for feeding the original fabric is switched from high speed to low speed, and at the same time as the detection, a timer is activated, and when the timer has counted the set time, the speed change means is operated in reverse to start feeding the original fabric. Switching the roll device from low speed to high speed.

て制御は行えないことになる。Problems that the invention aims to solve According to this conventional configuration, many types of bags with different lengths (for example, 10 cm to 100 cm) are made, and at that time, the feeding time by the roll device for intermittent transfer of the original material is limited. adjusted. Furthermore, the set time of the timer is adjusted in response to this adjustment, but it is difficult to adjust the timer accurately, and in reality, the work relies on intuition. Therefore, the amount (length) of low-speed feed during time measurement tends to be uneven. Normally, the change in the amount of sagging from when intermittent transfer stops to when it starts is 1/4 of the bag making length. Since the level change is 2.5 cm at a time, it can be done without any problem even if the timer's time adjustment is slightly incorrect. However, when making a 100 cm bag, for example, the level change upwards at the lowest point of sag is 25 cm at a time, so when the time adjustment goes out of order, there will be no sagging at all, and the tension mentioned above will occur. . Furthermore, since the frequency of switching is high, damage to the device is likely to occur.
This means that control cannot be performed using a timer when making long bags.

たがつて調整は正確に行える。According to the configuration of the present invention, when the sagging of the original fabric occurring between the original fabric feed roll device and the original fabric intermittent transfer roll device becomes below a certain height and is detected by the sensing device, The detection signal is applied to a switching circuit to switch the switching circuit, thereby switching the motor from high speed to low speed. As a result, the amount of feed of the original fabric decreases, so the amount of sagging gradually decreases. The aforementioned detection signal is also given to the measuring device at the same time to activate this measuring device. The amount measured by this measuring device measures the rotational length of the drive roll, so it is equal to the amount of the original fabric fed at low speed by the original fabric feeding roll device.
By measuring the set value of this measuring device, a switching signal is given to the switching circuit, and this switching circuit is switched.
The motor is switched from low speed to high speed. That is, the motor is automatically switched to high speed only when the low speed feed reaches a predetermined feed amount (predetermined length). When changing the bag making length, the set value may be adjusted. This adjustment is based on the rotation length of the drive roll.
Based on its diameter it can be easily calculated and adjustments can therefore be made accurately.

ことができ、したがつて調整は正確に行える。 The bag making work will be explained below. In FIG. 1, the solid line indicates the normal bag making state. That is, the intermittent drive roll shaft 17 is rotated forward and backward by the operation of the intermittent drive device 16, and thereby the roll device 5 for feeding the roll 5, which is continuously rotating at high speed, moves the roll holding device 1.
The original web 2 is fed while being rewound, and the original web 2 is further intermittently transferred by the roll device 9 for intermittent transport of the original web.
are welded by the heat welding blade 31 and sheared by the shearing device 27 during the intermittent stop. In this state, the sagging of the web 2 that occurs between the roll device 5 for feeding the web and the guide roll 8 gradually increases, and when this sag reaches a certain height or less, it is detected by the phototube device 33 as shown by the imaginary line. When it is done,
The detection signal A is applied to the switching circuit 37, and the switching circuit 37 is switched to switch the motor 36 from high speed to low speed. As a result, the feed amount of the original fabric 2 decreases, so that the amount of drooping gradually decreases.
The aforementioned detection signal A is also applied to the switch 39 at the same time, and this switch 39 is turned on to operate the measuring device 38. Since this measuring device 38 measures the rotational length of the drive roll 7, the measured amount is equal to
It is equal to the feed amount at low speed. The measurement signal L from the measuring device 38 is compared with a set value in a comparator 40, and when they become equal, it means that feeding of a predetermined amount has been completed. As mentioned above, when the comparison becomes equal, the switching signal C is given from the comparator 40 to the switching circuit 37,
This switching circuit 37 is switched, and the motor 36 is switched from low speed to high speed. That is, the motor 36 is automatically switched to high speed only when the low speed feed reaches a predetermined feed amount (predetermined length). When changing the bag making length, use comparator 4.
The setting value at 0 may be adjusted. Since the reference for this adjustment is the rotational length of the drive roll 7, it can be easily calculated based on its diameter, and therefore the adjustment can be performed accurately.
