On the way, it is rolled up into a cylinder, and the confectionery pieces are wrapped inside at regular intervals. The cylindrical wrapping paper is separated into individual pieces between the front and rear wrapped confectionery pieces while the cylindrical wrapping paper is separated into individual pieces between the front and back wrapped confectionery pieces, and then the cylindrical wrapping paper is separated into individual pieces between the front and rear wrapped confectionery pieces, and then the cylindrical wrapping paper is separated into individual pieces between the front and rear wrapped confectionery pieces. A conventional twist wrapping machine (for example, Utility Model Publication No. 37-27976) that twist-wrappes confectionery pieces through a series of assembly operations in which a twist-sealing member that moves in the same direction applies a twist-seal to the open tube opening of the wrapping paper.
can twist-wrap confectionery pieces at high speed and with high efficiency;
The spacing between the confectionery pieces wrapped in the wrapping paper, that is, the length of the wrapping paper for one confectionery piece, is determined by the arrangement interval of the holding members, so the length of the wrapping paper for one confectionery piece is determined according to the size of the confectionery piece. There was a drawback that it was not possible to change the size to change the length.

The object of the present invention is to provide a method and apparatus for feeding confectionery and wrapping paper, which can eliminate the above-mentioned disadvantages of conventional twist wrapping machines, the construction of which will be explained in detail with reference to the illustrated embodiment. The examples are as follows.

The confectionery pieces a are fed at regular intervals through a feeding gutter 3 by a pushing rod 2 that advances at regular intervals along with an endless chain band 1, and the long strip-shaped wrapping paper b is fed onto a collection reel (not shown). The confectionery pieces a are drawn out from below the feed gutter 3 and travel in the same direction as the confectionery pieces, meeting with the confectionery pieces a sent out from the feed gutter in front of the outlet of the feed gutter 3.
In the figure, reference numeral 414l denotes a clamping transfer belt installed oppositely on both sides along the course of the confectionery piece a and the long strip-shaped wrapping paper b, and includes belt wheels 5, 6, 7 and 7, respectively. 5/, 5/, 7/, belt pulleys 5, 5

29 and 30 are confectionery piece guides that prevent confectionery pieces passing between the belts 17 and 17' from escaping vertically; 31 is an endless guide on the path of the confectionery piece a transferred by the second transfer belts 11 and 17'; Accompanied by the chain band 32, the bells pass through the confectionery pieces at equal intervals in a uniform direction and at a constant speed, while the bell} 1 7 , 1 7 /
A supporting member 33 is a cylindrical wrapping paper that can be held by the supporting member 31, and the supporting member 33 is configured to sandwich the confectionery pieces a to be transferred from above the cylindrical wrapping paper b and take them out one by one from the delivery port of the transfer belt. A known twist-sealing member is shown which moves along the path of the clamping member opposite the opening of the cylinder shown in b at a constant speed and in the same direction as the supporting member, and twists and seals the opening of the cylinder in the course of its progress.

In the embodiments of FIGS. 1 and 2, however, the second transfer bell} 17. 1 7' is omitted, and the confectionery pieces a sent out from the transfer belts 4, 4' are successively held by the holding member 31 from above the cylindrical wrapping paper b, and at the same time, the rotary scissors 16,
At 16', the cylindrical packaging between the front and rear wrapped confectionery pieces is separated.

The confectionery pieces sent out from the feed gutter 3 at regular intervals are held together with the band-shaped wrapping paper b which is pulled out while being bent in a U-shape along the lower surface of the feed gutter 3. ' When the confectionery pieces a are fed into the U-shaped wrapping paper, they are inserted into the U-shaped wrapping paper at equal intervals via a belt and advance, while one edge of the U-shaped wrapping paper is held by the guide plate 14. The feeding speed of the confectionery piece a and a preset bell} 4, According to the relationship of the advancing speed of 4', the confectionery pieces a are wrapped at every predetermined interval length of the wrapping paper.In other words, if the set speed of the belt is slowed down, the interval between confectionery pieces is inserted becomes shorter, and if it is made faster It becomes longer.

Next, in the embodiment shown in FIGS. 1 and 2, the wrapped confectionery pieces a of the cylindrical wrapping paper wrapped at the desired intervals are sent out from the clamping transfer bells 4 and 4', and } 4
, 4', a clamping member 3 that can advance at regular intervals at a faster speed than 4'.
At the same time, the rotating scissors 1 6 and 1 6' cut the cylindrical wrapping paper between the front and rear wrapped confectionery pieces, and the wrapping paper is separated into individual confectionery pieces and held. The cylindrical wrapping paper b held by the member 31 and its inner confectionery piece a are then transferred at the advancing speed of the holding member, and during the transfer, as is well known, the supporting member rotates 90 degrees and faces the opening of the supporting wrapping paper. The cylindrical wrapping paper b is moved by the twisting wrapping member 33.
A twist seal is applied to the opening of the barrel.

In the embodiments shown in FIGS. 3 and 4, the transfer bell}
The cylindrical wrapping paper b sent out from 4 and 4' is held by the holding member 3
1 7
, 1 7', the traveling speed of this belt is faster than that of the first transfer bells} 1 7, 1 7' and the wrapped confectionery pieces of the wrapping paper. At this time, the cylindrical wrapping paper between the front and rear wrapped confectionery pieces is transferred between the first and second transfer belts by the rotating scissors 1.
6 and 16', the cylindrical wrapping paper b and its inner confectionery piece a, which have been cut into individual pieces, are then transferred to the second transfer bell at a speed of 17 and 17'. Immediately before it is sent out from the transfer belt, it is clamped by the supporting member 31 at the right timing, and then, as is well known, during the transfer by the clamping member 31, the supporting member 31 rotates 90 degrees and the supporting member 31 rotates 90 degrees to the tube opening of the supporting wrapping paper. A twist seal is applied to the open tube opening of the wrapping paper by the twist wrapping member 33 which is advanced in the opposite direction.

As described above, the present invention feeds the fed confectionery pieces and the band-shaped wrapping paper between the clamping transfer belts whose transfer speed can be set to an arbitrary speed slower than the supporting member, and transfers them at the set speed of the transfer belt, During this time, the wrapping paper is wound into a cylindrical shape, and the fed confectionery pieces are encased in the wrapping paper at desired intervals determined by the relationship between the feeding speed and the set speed of the belt, and then sent out from this transfer belt. Confectionery pieces wrapped in cylindrical wrapping paper are successively held by the supporting member that advances at regular intervals along its path at a constant speed, and at the same time one cylindrical wrapping paper is sequentially placed between the front and rear wrapped confectionery pieces. Since the wrapping paper is separated into pieces and transferred to the twist-sealing section using a holding member, in the conventional series of operations for this type of twist-wrapping, the band-shaped wrapping paper is pulled out at the advancing speed of the supporting member, which causes the holding member to move. The interval between the pieces of confectionery wrapped in the wrapping paper, that is, the length of the wrapping paper for one piece of confectionery, is determined invariably by the arrangement interval of the members, and the length of the wrapping paper for one piece is determined according to the size of the confectionery piece. Except for the drawback that it could not be changed, the length of wrapping paper required for the size of the confectionery piece can be arbitrarily selected by changing and setting the traveling speed of the adhesive transfer belt to a desired speed in advance. This type of twist packaging allows for twist wrapping of arbitrary pieces of confectionery with different lengths of wrapping paper for one piece of confectionery using a single wrapping machine. It is something that can be attached to a machine.
