Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved method and apparatus for automatically wrapping confectionery pieces with one twist.

As a packaging means for automatically and efficiently wrapping confectionery pieces at high speed through a series of flow operations, a long strip of wrapping paper is generally used to wrap confectionery pieces at equal speed and in the same direction as the confectionery pieces are fed at regular intervals. A work style is adopted in which various operations such as wrapping the confectionery pieces, separating the wrapping paper, and sealing are carried out sequentially and continuously during the progress of the two processes. Although this can be easily applied to heat-sealed packaging such as the three-sided seal packaging shown in A in the figure, it cannot be applied to double-twist packaging as shown in B in Figure 2 or single-twist packaging as shown in C in Figure 2. Conventionally, when applying a wrapping paper that wraps confectionery pieces and progresses horizontally, twisting could not be applied unless the wrapping paper was vertically erected (for example, Japanese Patent Publication No. 39-11143). (Refer to the official publication) The work process and equipment inevitably became more complicated.

The object of the present invention is to provide a packaging method and a device by which the above-mentioned conventional drawbacks in twist packaging of automatically wrapped confectionery pieces can be eliminated as far as single twist packaging is concerned.

The configuration of the present invention will be described in detail below with reference to the illustrated embodiments.

The single-twist wrapped confectionery piece that is packaged by the method and apparatus of the present invention is obtained by folding over both edges of the wrapping paper b, which is folded in two and covering the confectionery piece a, as shown in Fig. As shown in the figure, the bag is made into a bag by heat-sealing c, and the bag opening d is closed.
A twisted seal e is applied to the side as shown in Figure C.

Next, in the embodiment of the packaging method and apparatus of the present invention shown in FIGS. The long strip-shaped wrapping paper b is pushed into the water supply gutter 1 at equal intervals by the pushing member 3, which is moved in the direction of It is pulled out and moves above the water supply gutter 1 at the same speed and in the same direction as the confectionery piece a in the gutter, and when it passes inside the packaging guide member 5 fixed above the water supply gutter 1, it follows the inner curved surface of the confectionery piece a. The confectionery pieces a that are folded in half in an inverted U-shape in the width direction and covered from the outside of the feed gutter 1 to the confectionery pieces that advance in the gutter, and thus sent out from the feed gutter 1, are wrapped in an endless chain band 6. At the return position of the tying member 7, the tying piece 7a and 7b of the holding member of the tying conveyance mechanism equipped with the holder 7, which rotates at regular intervals along the circulation route as the tying member 7 is moved, is covered. The wrapping paper is sandwiched one by one from above and conveyed forward together with the wrapping paper b.

At this time, the ball holding pieces 7a and 7b are closed by the cam 8 via the operating punch 9, and after passing through the return point, they are closed at the end of the cam 8 to clamp the confectionery piece together with the wrapping paper. Since one clamping piece 7a passes above the wrapping paper b, it is necessary to open the clamping pieces 7a and 7b more than the other clamping piece 7b. The pinion gear ratio must be different. 1 in the figure is an upper and lower guide portion for moving the holding member 7 in a stable state. Next, heater blocks 11a and 12a are mounted on the rotating circumferences of a pair of rotary bodies 11 and 12, which rotate oppositely to each other and are spaced apart from each other in the path of the leaf pieces and the wrapping paper that are pinched and conveyed by the holding member 7. The sides of the heat sealing loom are installed at equal intervals, and the heater blocks 11a and 12a are successively brought together at a distance from each other by keeping the folded wrapping paper between the confectionery pieces before and after the confectionery pieces are pinched and conveyed by the holding member 7. By rotating the rotating bodies 11 and 12 in synchronization with the advance timing of the holding member 7, the folded wrapping paper is joined in the width direction between the assembled heater blocks and heat-sealed, and at the same time, the heater flock 11 side is The wrapping paper is sequentially cut back and forth at the center of the sealing position by a push-cutting blade 13 provided in the wrapping paper.

Thus, as shown in FIG. 1B, the wrapping paper b, which is divided into bag-like pieces into which the confectionery pieces a are individually wrapped, passes around the return side chain ring 14 of the endless chain band 6, accompanied by the holding part village 7. In between, the bag is held by the gripping claws 15a of the gripping member 15 of a known twist packaging mechanism that rotates around the rotational axis of the chain 14 in the same direction and at the same speed as the gripping member, facing below the gripping member 7. After grasping the open end of the bag, and then twisting the opening of the bag by turning the gripping member 15 and wrapping it as shown in FIG. 7a and 7b are closed to release the packaged confectionery pieces.

That is, the conventional automatic packaging method and apparatus for wrapping confectionery pieces is to cut the confectionery pieces between the confectionery pieces while moving the confectionery pieces forward while holding the confectionery pieces from above the wrapping paper in which the confectionery pieces are rolled into a cylindrical shape using a holding member. Opening the wrapping paper □ Since the opening of the wrapping paper had been twisted and wrapped, the opening of the wrapping paper to which the twisting should be applied runs parallel to the traveling path. Therefore, the holding member was rotated 90 degrees to open the wrapping paper at right angles to the traveling direction. The opening of the wrapping paper could not be twisted and sealed by the gripping part of the twisting wrapping mechanism that moves in opposition to the holding member unless the wrapping paper is raised upright or the wrapping paper is transferred using another holding member. However, the method and device for automatically wrapping confectionery pieces of the present invention, as described above, wraps the confectionery pieces over the wrapping paper folded in half and moves the confectionery pieces forward while being held by the holding member. Wrapping paper is glued together between the front and back confectionery pieces, heat-sealed, and then the wrapping paper is cut back and forth in the center to form a vertical bag.The wrapping paper is then twisted and sealed at the opening of the bag. Since the wrapping paper is made to be woven, the closing bag opening of the wrapping paper that is held by the clamping members and advanced is oriented in a direction perpendicular to the direction of travel of the wrapping paper. It is possible to immediately apply a twist seal to the confectionery piece using the gripping member of the present invention, and the packaging process and equipment can be simplified compared to existing methods and devices for automatically wrapping confectionery pieces. In the past, when wrapping a long confectionery piece such as a bar-shaped confectionery piece in a twist-sealed package, it was impossible to wrap the confectionery piece horizontally, so the end side in the longitudinal direction of the confectionery piece was However, in the present invention, as shown in Fig. 1C, since the confectionery pieces can be wrapped horizontally, a twist-sealed IJ bong with a width comparable to the entire length of the confectionery piece in the longitudinal direction can be formed. It is possible to form,
This makes it possible to make the single-twist packaging form of automatically wrapped confectionery pieces, which have the elegance of a genuine pot, even more elegant.
