For example, switches that are operated by touching corresponding portions of the touch panel, and other types of switches It can be adopted.
[0029]
Instead of individually arranging the control devices 18A and 18B for each packaging unit, the first packaging unit 11 and the second packaging unit 12 can be configured to be controllable by one control device, A control system can be adopted as appropriate. The emergency stop switches SW3A and SW3B constitute the emergency stop switches SW3A and SW3B with one contact corresponding to the packaging parts 11 and 12, instead of the configuration in which the contact parts are individually provided for the packaging parts 11 and 12. Various other control methods, such as processing in software in each control device to cut off the drive signal to the control target means of each packaging part 11 and 12 when one of the emergency stop switches SW3A and SW3B is operated Can be adopted. When the emergency stop switches SW3A and SW3B are operated, not all the control target means are stopped, but a mechanism that is hidden inside the machine and is not required to be stopped for safety of work, The control target means corresponding to the conveyors 29A and 29B may be excluded from the emergency stop target.
[0030]
【The invention's effect】
As described above, according to the horizontal bag making and filling machine according to the present invention, when any one of a plurality of packaging parts for individually manufacturing a packaging body is defective in packaging, or an emergency stop is required due to other factors, Since the control device stops the operating mechanism in which all the packaging parts are operated by the stop operation of the emergency stop switch , the safety of the post-processing operation can be ensured.
In addition, the control device operates even when the emergency stop switch corresponding to the packaging unit that is different from the packaging unit requiring an emergency stop and is in a stopped state or in a state where the power supply is shut off is operated. Since the operation of the control target means in operation is stopped in all the packaging parts in the inside, the operator does not need to select and operate the switch, and can quickly stop the packaging part that needs an emergency stop.
