(C) is a side view of (b), and (d) is the removal of a defective product when there is a bite of an ingredient packaged in a sachet or some trouble. FIG.

  As shown in FIG. 1, the tape applicator 1 (see FIG. 2) is a belt-like shape having a certain width by connecting a plurality of sachets 2 wrapping food ingredients such as powder, granular, and chopped shapes. In order to continuously add the body 3 and the succeeding belt-like body 4 to the preceding belt-like body 3 and send them in the traveling direction, the seam is stuck so as to cover with the adhesive tape 5. The preceding belt-like body 3 and the subsequent belt-like body 4 have the same shape, such as a difference in production lots.

As shown in FIG. 1A, first, the rear end surface 3ba of the leading end 3b of the preceding strip 3 and the leading end surface 4aa of the leading end 4a of the succeeding strip 4 with respect to the leading strip 3 Are attached with diagonal lines.
Then, as shown in FIGS. 1B and 1C, the preceding strip 3 and the subsequent strip 4 are abutted. The adhesive tape 5 is attached to the upper surface, the side surface, and the lower surface while covering the abutting contact position 2a.

  The position where the adhesive tape 5 is affixed goes from the upper surface 3bb, 4ab including the contact position 2a of the preceding belt-like body 3 and the following belt-like body 4 to the side surfaces 3bc, 4ac and further to the lower surfaces 3bd, 4ad. paste. Adhesion of the adhesive tape 5 to the lower surfaces 3bd and 4ad becomes a continuous region from the upper surfaces 3bb and 4ab through the side surfaces. It is in a state of being folded back to the lower surface. The adhesive tape 5 may circulate around the entire contact position 2a. As a result, a belt-like body in which the sachets 2 are connected. Here, the adhesive tape 5 is wrapped around the upper surface 3bb, 4ab, the side surface 3bc, 4ac and the lower surface 3bd, 4ad of the tape application region 2a of the strips 3 and 4, so that the transverse dimension (width) of the sachet is 80 mm. In this case, the adhesive tape 5 is attached to the tape application region 2a with a length of about 120 mm.

  As shown in FIG. 1 (d), the reason why the strips 3 and 4 must be connected is that when the preceding strip and the following strip are joined to form a longer continuous strip, When a defective product is removed from a continuous belt-like body, for example, if it is necessary to remove the sachet (b) in the figure (d), the sachet (b) is cut out and the sachet is placed behind the sachet (b). In this case, (c) is pasted with adhesive tape.

As shown in FIGS. 2 (a) and 2 (b), the preceding strip 3 is sent out from the tape applicator 1 and stacked and stored in the product storage box, and eventually the leading strip 3 comes to an end. By detecting the terminal end, the roll-shaped belt 4 is then supplied to the tape applicator 1. The detection of this end will be described later.
The tape applicator 1 includes a rail portion 1a that supports a preceding belt-like body 3 and a subsequent belt-like body 4 from below and guides movement in a predetermined traveling direction, and a rear end 3b of the preceding belt-like body 3 is a rail portion. A first presence / absence detector 1b that detects passage through the outlet side 1ab of 1a, and a second presence / absence detector 1c that detects that the leading end 4a of the subsequent strip 4 has arrived at the inlet side 1aa ing.

The tape applicator 1 is arranged so that the preceding band 3 blocks the first presence / absence detector 1b, and the subsequent band 4 blocks the second presence / absence detector 1c. By pressing a start switch (not shown), the preceding belt-like body 3 moves backward on the rail portion 1a by a predetermined distance, and the succeeding belt-like body 4 moves forward on the rail portion 1a by a predetermined distance. The rear end surface 3ba and the leading end surface 4aa of the subsequent strip 4 are controlled so as to automatically stop.
At this time, the start position where the preceding belt-like body 3 starts moving backward is a position where the first presence / absence detector 1b detects the rear end 3b of the preceding belt-like body 3. The start position at which the subsequent strip 4 starts moving is the position at which the second presence / absence detector 1c detects the tip 4a of the subsequent strip 4. The detection positions of the first and second presence / absence detectors 1b and 1c are home positions at which the movement to the contact position starts.
