Embodiment Construction

[0029] Below, based on Figure 1 to Figure 21 The connecting device 10 of the sheet W according to one embodiment of the present invention will be described. The connection device 10 uses a suction device 100 , a cutting device 46 , and a negative pressure device 150 . Here, the "sheet W" refers to a long sheet, such as fabric, paper, film, metal foil, and the like. In addition, in the connecting device 10 , the "input side" refers to the upstream where the sheet W is conveyed, and the "output side" refers to the downstream where the sheet W is to be conveyed.

[0030] In the connection device 10, such as figure 1 As shown, the remaining old sheet W1 wound on the previous core 1 is reduced, so the new sheet W2 wound on the new core 2 is connected after the old sheet W1.

[0031] Such as figure 1 and figure 2 As shown, the old sheet W1 and the new sheet W2 are conveyed via the conveyance path in the horizontal direction. Such as figure 1 As shown, the old sheet W1 passe...

Abstract

The invention provides a suction device and a web coupling apparatus using the same, the suction device capable of easy suction. The suction device includes a first coupling pipe (124) that couples a negative pressure vessel (114) and a negative pressure pump (110); and a second coupling pipe (126) that couples a suction portion and the negative pressure vessel (114); a two-way valve (118) which is provided in the middle of the first coupling pipe (124); a suction three-way valve (120) which is provided in the middle of the second coupling pipe (126), an inlet being coupled with the negative pressure vessel (114), a first output being coupled with the suction portion, and a second output being open to the outside.

Description

[0001] This application is based on Japanese Patent Application No. 2015-124971 (filing date: June 22, 2015), and priority is claimed based on this application. This application incorporates the entire content of this application by reference. technical field [0002] The present invention relates to a suction device and a sheet connecting device using the suction device. Background technique [0003] Conventionally, for the connecting device that connects the old sheet and the new sheet, the first step is to overlap the old sheet and the new sheet, the second step is to clamp the front and rear of the part to be cut with the sheet holder, and the third step is to The first step is to use a cutter to cut off the old and new sheets at the cutting position at the same time. The fourth step is to use the suction surface of the sheet holder to suction and hold the rear end of the old sheet and the front end of the new sheet, and put the old and new sheets together. All unnecess...
