Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging method, and more particularly to a method for packaging a plurality of confectionery pieces in a tubular shape with a single wrapping paper.

[0002]

2. Description of the Related Art Recently, some packaging of confectionery pieces adopts a packaging form in which a plurality of small confectioneries are packaged together. This product has an advantage in that only a necessary amount can be eaten according to taste, and it is not necessary to fold or cut a confectionery piece of a certain size into small pieces.

Conventionally, such a packaging form is shown in FIG.
The following form is adopted. In this product, a predetermined number of confectionery pieces are collected as a group and are packaged in a vertical bag-making packaging. In this case, since a predetermined number of confectionery pieces are accommodated in a non-aligned state in a packaging bag formed from a band-shaped wrapping paper, a large number of these packaged confectionery pieces in a bag can be used, for example, for packaging. When repacking in a box, there is a lot of wasted space in this packing box, resulting in poor packing efficiency.

The present invention has been made in view of the above points, and enhances the packaging efficiency when repacking a plurality of confectionery pieces in a packaging box so that they can be packaged in a line, and It is an object of the present invention to enable high-speed packaging and, in addition, prevent the confectionery pieces from being damaged during the transfer of the confectionery pieces to the packaging process section. [Invention of Claim 1]

[0005]

[Technical Means] A technical means of the present invention for solving the above-mentioned problem is that "a large number of transfer rods (21) (21) travel at a predetermined interval in a linear transfer path that opens upward. A series of confectionery pieces in which a predetermined number of confectionery pieces (A) and (A) are arranged in a line by providing a straight transfer path (2) having a configuration and transferring each confectionery piece (A) by each of the transfer rods (21) Group (A ₁ ) (A ₁ ) through the straight transfer path
(2) Run straight at regular intervals and strip the wrapping paper.
(1) is molded into a tubular body in which both side edges face each other at the lower side, and the confectionery pieces (A) and (A) that run in a straight line are thereby surrounded, the tubular body molding step The straight transfer path
It is connected to the end point of (2) and the traveling direction of the tubular body of the band-shaped wrapping paper (1) is set to be coaxial with and in the same direction as the linear transfer path (2). At the end point, each transfer rod (21) is allowed to escape downward from the tubular molding step, and both side edges of the strip wrapping paper (1) are heat-sealed downstream of the tubular molding step. , Furthermore, on the downstream side of this heat seal part,
A process section for end-sealing between the series confectionery piece group (A ₁ ) (A ₁ ) and dividing into front and back is provided, and the traveling speed of the band-shaped wrapping paper (1) is set to be slower than that of the transfer rod (21). That's it.

[0006]

The above technical means operates as follows. Each confectionery piece (A) was pushed by the transfer rod (21) and transferred in the linear transfer path, and a predetermined number of confectionery pieces (A) (A) became a series confectionery piece group (A ₁ ). In this mode, the series confectionery piece groups (A ₁ ) and (A ₁ ) are run with a certain interval. Then, at the end point of this traveling area, the strip-shaped wrapping paper (1) is folded in two in an arc shape, and is molded into a tubular body in a manner that both side edges of the strip-shaped wrapping paper (1) face each other at their lower sides and are in close proximity to each other.

In this tubular body molding process section, each confectionery piece (A)
The transfer rod (21) that pushes out the paper into the strip-shaped wrapping paper (1) on the downstream side is
Since it escapes downward, and the traveling speed of the strip-shaped wrapping paper (1) is set slower than that of the transfer rod (21),
The confectionery pieces (A) (A) forming the series confectionery piece group (A ₁ ) are densely continuous. Moreover, the series confectionery piece group (A ₁ ) (A ₁ ) is accommodated and held in the tubular band-shaped wrapping paper (1) in a state where a certain interval is left open, and the straight line is formed. Transfer route
It is transferred coaxially further downstream from the downstream end of (2).

Then, at a predetermined position distant from the downstream end of the straight transfer path (2) to the downstream side, both side edges of the strip-shaped wrapping paper (1) are heat-sealed to form a tubular wrapping having a circular cross section. The confectionery pieces (A) (A) are contained in the paper in such a manner that the confectionery pieces (A ₁ ) (A ₁ ) are arranged at a constant interval. Then, in the end-sealing step, the tubular wrapping paper portion between the series confectionery piece groups (A ₁ ) (A ₁ ) is fusion-sealed.

As a result, the confectionery pieces (A) (A) are packaged in a line. Moreover, since this packaging process consists of linearly continuous processes, confectionery pieces
(A) Even if the transfer speed of (A) and the traveling speed of the band-shaped wrapping paper (1) are increased, packaging defects are less likely to occur.

[0010]

[Effect] Since the confectionery pieces (A) and (A) of the series confectionery piece group (A ₁ ) are packed in a line in a cylindrical wrapping paper, the packed series confectionery piece group (A ₁₎ ) Is packed in the packaging box,
There is no wasted space. That is, the packaging efficiency is good. Each process for wrapping the series confectionery piece group (A ₁ ) in the strip wrapping paper is linearly continuous, and the transfer speed of the confectionery pieces (A) (A) and the strip wrapping paper
Since the traveling speed of (1) can be increased, the packaging work can be accelerated. That is, the packaging work can be efficiently performed.

Further, since each confectionery piece (A) is transferred so as to be extruded separately by the transfer rod (21) in the straight transfer path (2), the confectionery piece (A) is transferred in the straight transfer path (2). (A) It is possible to prevent damage to the confectionery piece (A) due to direct contact with each other. Since the confectionery pieces (A) (A) in one packaging unit are in a closely continuous manner, the length of the wrapping paper required for one packaging unit is minimized.

[Other invention] In the invention of claim 2, in the invention of claim 1, a predetermined number of confectionery pieces (A) and (A) are connected as a series confectionery piece group (A ₁ ) to the linear transfer path (2). The means used for this purpose is to ensure smooth transfer, "above the upstream end of the linear transfer path (2), a predetermined number of through holes (31) ( The plate-shaped disk (3) is arranged with the through-hole group (30) (30) consisting of (31) arranged on the circumference at a predetermined interval.

In a mode of being housed in a group of a predetermined number of series confectionery pieces (A ₁ ), the series confectionery piece group (A) housed in the through hole groups (30) (30)
₁ ) (A ₁ ) There is a predetermined space between each other. Then, when each confectionery piece (A) coincides with the through hole (31) and the opening (41), it is dropped in the vicinity of the upstream side of the transfer rod (21) of the linear transfer path (2) located therebelow. .

Therefore, the confectionery piece (A) is surely positioned in front of each transfer rod (21) in the straight transfer path (2) having a U-shaped cross section. The rotation speed of the straight transfer path (2) and the straight transfer path
Since the interval and the traveling speed of the transfer rods (21) and (21) of (2) are set to a predetermined relationship, the confectionery pieces (A) and (A) falling from the through holes (31) are Series of confectionery pieces with intervals (A ₁ ) (A ₁ )
Therefore, the vehicle travels on the upper surface of the straight transfer path (2).

Further, in the straight transfer path (2), the transfer rods (21) and (21) are projected from the bottom of the passage having a U-shaped cross section, so that the lower part is partially released at the end point thereof. After the confectionery pieces (A) and (A) are fed into the tubular wrapping paper, the tubular wrapping paper can be smoothly escaped. In addition, as defined in claim 3, "straight transfer path"
A support piece supporting the confectionery piece (A) from below is provided between the heat-seal part and the downward escape part of the transfer rod (21) following the end point of (2). The transfer operation into the strip-shaped wrapping paper (1) formed into a tubular body on the downstream side of the path (2) is smooth, and there is no risk of the confectionery pieces (A) (A) spilling during this transfer. .
