Patent number: 11136155Abstract: A bag-making and packaging machine packages, in bags made from a film, articles discharged and dropped from an article discharge apparatus. The bag-making and packaging machine has a transverse sealing mechanism, a receiving member, a vertical moving mechanism, and a control unit. The transverse sealing mechanism transversely seals a film tube. The receiving member contacts an outer surface of the film tube above the transverse sealing mechanism and receives the articles A that drop through the inside of the film tube. The vertical moving mechanism moves the transverse sealing mechanism and the receiving member in the up and down direction. The control unit switches between a first mode and a second mode. In the second mode, the receiving member contacts the outer surface of the film tube at a lower height position than in the first mode.Type: GrantFiled: December 5, 2019Date of Patent: October 5, 2021Assignee: ISHIDA CO., LTD.Inventors: Shinji Koike, Kento Fujita

Patent number: 11046468Abstract: A bag-making and packaging machine has a film supply unit that supplies film to a bag-making and packaging unit. The film supply unit has a film conveyance mechanism that conveys a first film so that a trailing end portion of the first film heads toward a film splicing position for splicing to a leading end portion of a second film, a first sensor detecting a mark on the first film, a second sensor detecting the mark at downstream, and a controller for the film conveyance mechanism. The controller judges, based on detection of the second sensor, that the trailing end portion of the first film has reached the splicing position and stops conveyance of the first film. The controller controls the conveyance mechanism so that the conveyance speed of the first film before the detection of the mark by the first sensor is faster than the speed after the detection.Type: GrantFiled: October 3, 2019Date of Patent: June 29, 2021Assignee: ISHIDA CO., LTD.Inventors: Takafumi Shimoda, Yuchuan Tong, Ryota Nagashima, Shinji Koike
