Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bread wrapping and packaging method for bread that feeds bread to be bagged into an opened bag.
[0002]
[Prior art]
There has already been proposed a bagging device configured to feed articles to be bagged into a bag opened by the bag opening device.
A bag to be filled with goods is opened by air blowing by a bag opening method as disclosed in, for example, Japanese Patent Laid-Open No. 2000-255514, and an opening member such as a chuck is inserted into the opening to greatly widen the opening. It is done.
[0003]
An article to be filled in the bag is inserted through the opening thus expanded. The article can be inserted into the opened bag by, for example, a bag-filled article feeding apparatus disclosed in Japanese Patent Laid-Open No. 6-286704 proposed by the present applicant.
[0004]
FIGS. 3 to 6 show the operation of feeding an article into the bag by the bag-packed article feeding apparatus. The article B to be packed is gripped from both sides by the gripping member 1 as shown in FIG. 3, and the rear of the article B is supported by the engagement piece 3. Reference numeral 2 denotes a sliding holding device that holds the gripping member 1 that slides in the direction of the arrow.
[0005]
The gripping member 1 that grips the article B is displaced forward, and proceeds to the opening of the packaging bag E whose opening is expanded by the chuck 30 as shown in FIG. Enter (Figure 4). The gripping member 1 is slightly expanded between each other by the operation of a gripping member operating device (not shown), the gripping of the article B is released in the bag E, and the engagement piece 3 is also returned from the protruding position to the original position. (FIG. 5). Then, the gripping member 1 is retracted from the inside of the packaging bag E, and the article B is left in the packaging bag E (FIG. 6). In this way, the packaging bag E into which the articles are put by the bag-filled article feeding apparatus is appropriately closed by the apparatus (not shown) to complete the bag packing.
[0006]
As described above, an article to be packaged in the opened packaging bag E, for example, bread is fed and filled from the opening, but the packaging bag into which bread is fed is filled with air. Since the bread is fed into the packaging bag from the opening, the air in the packaging bag is pushed in by the piston action of the fed bread and the packaging bag is inflated into a cylindrical shape.
[0007]
In this state, if the square bread is continuously fed into the cylindrically inflated packaging bag, an excessive force is applied to the packaging bag. In particular, when the article to be inserted into the packaging bag is a square bread, the solid corner of the bread inserted into the bag hits the inner surface of the bag inflated in a cylindrical shape as shown in FIG. The corners will rub the inner surface of the bag.
Therefore, the inner surface of the packaging bag may be damaged at the corner of the bread that is continuously inserted, and the bag may be torn.
As described above, in the conventional bread bag packing, there is a problem when the bread to be packed in the opened bag is fed from the opening.
[0008]

[0010]
According to this bread bag packing and packaging method of the present invention, the opened bag is squeezed by crushing before the bread is fed and the internal air is partially expelled, so the bag into which the bread is inserted There is only a little air inside, and when bread is inserted into the bag through the expanded opening, the bag will be inflated while being expanded by the piston action of the inserted bread, making it impossible for the bag Air pressure does not act, and the corners of the bread do not rub the inner surface of the bag inflated cylindrically.
Therefore, according to the bread bag packaging method of the present invention, there is no situation where the packaging bag is damaged or broken by the corners of the bread to be fed.
[0011]
In the bread bag packing and packaging method according to the present invention, in order to dent the opened bag, an air jet is applied to the bag from the outside, or the bag is crushed from the outside with a bag pressing member that reciprocates. It can be done by various means.
[0012]
In the bread bag packing and packaging method of the present invention, when the bag temperature is increased by using hot air as an air jet to be blown when the bag is opened or an air jet to be blown when the opened bag is dented, the bag is packed. It is effective in avoiding the tearing of the bag by the corner of the bread.
Thus, the bread bag packaging method of the present invention can be carried out without using any special means.
