Title: Seal and cut unit for packaging material sheet
Inventor: SUZUKI YASUHIKO
IPC: B65B51/22
Filed: 2021-08-24
Abstract: To solve a problem that when seal strength is enhanced, cutting sharpness becomes dull by that amount, thereby having a cut surface with no clean cross-section, according to a receiving member having both a seal function and a cut function.SOLUTION: According to a reception port 35 constituted of a facing surface of an ultrasonic horn 13 and a receiving member, for example, a receiving roll 15, an execution distance (L1) of seal before cutting from a position at which the seal is started by displacing the receiving roll 15 to a position at which cutting is most adjacently made is secured. Further, the receiving roll 15 relatively moves to the ultrasonic horn 13 in a direction of nipping a packaging material sheet S. Accordingly, a clean cut face can be obtained together with a sufficient seal strength via preferential cutting during cutting. Further, crud (N) of a paste is generated and accumulated by dissolving the packaging material sheet S, but since the receiving roll 15 rotates, the crud (N) of the paste as a foreign matter is blown out to a supply side along with rotation thereof at a light step before increasing the same, and thus generation of seal failure caused by generation of the crud (N) of the paste can be inhibited.SELECTED DRAWING: Figure 7
