[0002]

2. Description of the Related Art In recent years, some confectionery pieces have been packaged in such a manner that a plurality of small confections are packaged together. This is advantageous in that only the required amount can be eaten according to preference, and there is no need to break or shred a piece of confectionery of a certain size into small pieces.

Conventionally, as such a packaging form, FIG.
The following form is adopted. In this device, a predetermined number of confectionery pieces are put together as a group, and the confectionery pieces are packaged in a vertical bag-making package. In this device, a predetermined number of confectionery pieces are accommodated in a non-aligned state in a packaging bag formed from a band-shaped wrapping paper. When repacking in a box, wasteful space is increased in the packing box, and the packaging efficiency is poor.

[0004] The present invention has been made in view of the above points, and it has been made possible to package a plurality of pieces of confectionery in a line so as to increase the packaging efficiency when repackaging in a packaging box, It is an object of the invention to enable high-speed packaging and , in addition, to ensure that the confectionery pieces are not damaged during the transport of the confectionery pieces to the packaging station.

[0005]

The technical means of the present invention for solving the above-mentioned problem is as follows: "A large number of transfer rods (21) run at predetermined intervals in a linear transfer path which opens upward. A linear transfer path (2) having the above configuration is provided, and each confectionery piece (A) is transferred by each of the transfer rods (21) so that a predetermined number of confectionery pieces (A) (A) are arranged in a line. Group (A ₁ ) (A ₁ )
(2) Run linearly at regular intervals at
(1) is molded into a cylindrical body in which both side edges are opposed to each other at the lower side, thereby enclosing the confectionery pieces (A) and (A) running straight, a cylindrical body molding process section The linear transfer path
(2), the traveling direction of the tubular body of the band-shaped wrapping paper (1) is set in the same direction as the linear transport path (2) in the same direction as the linear transport path (2). At the end point, each transfer rod (21) escapes downward from the cylindrical body forming step, and heat seals both side edges of the band-shaped wrapping paper (1) downstream of the cylindrical body forming step. , And further, on the downstream side of the heat seal portion,
An end seal is provided between the series confectionery pieces (A ₁ ) and (A ₁ ) to separate them back and forth, and the traveling speed of the band-shaped wrapping paper (1) is set to be lower than that of the transfer rod (21). , The straight transfer path (2)
A predetermined number of through holes (31) (3
A dish-shaped disk (3) having a group of through-holes (30) and (30) composed of 1) arranged on a circumference at predetermined intervals is arranged, and the confectionery accommodated in the dish-shaped disk (3) is rotated by rotating the dish-shaped disk (3). The pieces (A) and (A) are sequentially moved to the periphery and accommodated in the respective through-holes (31) and (31), and the series confectionery piece group (A ₁ )
The number of confectionery pieces (A) and (A) constituting the same as the number of through-holes (31) and (31) constituting the through-hole group (30) are matched, and each through-hole (31) is a confectionery piece.
(A) has a size that allows it to fall, and an auxiliary bottom plate (4) having an opening (41) in part is provided below the arrangement of the through holes (31) and (31), and the opening (41) is provided. And the confectionery pieces (A) and (A) are inserted through the through holes (31) and (31).
From the downstream side of the transfer rod (21) of the linear transfer path (2).

[0006]

The above technical means operates as follows. Each confectionery piece (A) is pushed by the transfer rod (21) and transported in the linear transport path, and a predetermined number of confectionery pieces (A) (A) become a series confectionery piece group (A ₁ ) In this mode, the vehicle runs in a mode in which there is a certain interval between the series of confectionery pieces (A ₁ ) and (A ₁ ). Then, at the end point of the traveling area, the band-shaped wrapping paper (1) is folded in two in an arc shape, and is formed into a tubular body in which both side edges of the band-shaped wrapping paper (1) are opposed to each other at the lower side.

[0007] In the cylindrical body molding process section, each confectionery piece (A)
The transfer rod (21) that pushes the paper into the belt-shaped wrapping paper (1) on the downstream side
Because it escapes downward, and because the traveling speed of the band-shaped wrapping paper (1) is set lower than that of the transfer rod (21),
The confectionery pieces (A) (A) constituting the series confectionery piece group (A ₁ ) are densely continuous. Moreover, the serial confectionery pieces (A ₁ ) and (A ₁ ) are housed and held in the tubular wrapping paper (1) in a state in which a fixed interval is kept open, and Transfer route
From the downstream end of (2), it is transported further downstream and coaxially.

Then, at a predetermined position distant from the downstream end of the linear transfer path (2) to the downstream side, both side edges of the band-shaped wrapping paper (1) are heat-sealed with each other to form a cylindrical wrapping having a circular cross section. The confectionery pieces (A) and (A) are accommodated in the paper in such a manner as to have a certain interval between the series of confectionery piece groups (A ₁ ) and (A ₁ ). Then, in the end sealing step, the tubular wrapping paper portion between the series of confectionery pieces (A ₁ ) and (A ₁ ) is welded and sealed.

As a result, the confectionery pieces (A) and (A) are packaged in a line. In addition, since this packaging process is made up of linearly continuous processes,
(A) Even if the transfer speed of (A) and the traveling speed of the band-shaped wrapping paper (1) are increased, defective packaging hardly occurs. Further, in the dish-shaped disk (3), a predetermined number of confectionery pieces (A) and (A) are accommodated in the through-holes (31) in the through-hole groups (30) and (30) on the periphery thereof, respectively. Series confectionery pieces
(A ₁₎ is classified as, Toruanagun (30) (30) to the stowed series confectionery pieces group (A ₁₎ (A ₁₎ a predetermined distance between each other is opened. Then, when each confectionery piece (A) coincides with the through hole (31) and the opening (41), the transfer rod (21) of the linear transfer path (2) located thereunder.
Is dropped near the downstream side of. Therefore, the confectionery piece (A) is securely inserted in front of each transfer rod (21) in the linear transfer path (2) having a U-shaped cross section.
Will be located. Since the rotation speed of the linear transfer path (2) and the interval between the transfer rods (21) and (21) of the linear transfer path (2) and the traveling speed are set in a predetermined relationship, each through-hole (31) The confectionery pieces (A) and (A) that fall from the above form a series of confectionery piece groups (A ₁ ) and (A ₁ ) having a predetermined interval, and travel on the upper surface of the linear transfer path (2). Further, since the linear transfer path (2) is configured such that the transfer rods (21) and (21) protrude from the bottom of the passage having a U-shaped cross-section, at the end point thereof, the cylinder is opened so that the lower part is partially released. After the confectionery pieces (A) and (A) have been fed into the wrapping paper, the wrapping paper can be smoothly escaped from the tubular wrapping paper. Then, the transfer rod (2) following the end point of the straight transfer path (2)
A support piece (19) for supporting the confectionery piece (A) from below is provided between the downward escape section of (1) and the heat sealing section. ' The transfer operation into the band-shaped wrapping paper (1) formed in the tubular body is smooth, and there is no fear that the confectionery pieces (A) (A) are spilled during this transfer.

[0010]

[Effect] Since the confectionery pieces (A) and (A) of the series of confectionery pieces (A ₁ ) are packaged in a line in a cylindrical wrapping paper, the packaged series of confectionery pieces (A ₁₎ ) Is packed in a packaging box.
No wasted space is created. That is, the packaging efficiency is good. The processes for wrapping the confectionery pieces (A ₁ ) in the wrapping paper are linearly continuous, and the transfer speed of the confectionery pieces (A) and (A) and the wrapping paper
Since the traveling speed of (1) can be increased, the packaging operation can be accelerated. That is, the packaging operation can be performed efficiently.

The confectionery pieces (A) are transported in the linear transfer path (2) so as to be individually pushed out by the transfer rods (21). (A) Damage to the confectionery pieces (A) due to direct contact with each other can be prevented. Since the confectionery pieces (A) (A) in one packaging unit are in a densely continuous form, the length of wrapping paper required for one packaging unit is minimized.
