Contents-filling vessel reversing apparatus and a vessel for use with the apparatus

Abstract

A contents-filling apparatus for use in a bag packaging machine. The apparatus comprises a reversing device including a rotating device for rotating intermittently a main rotating member around an axis thereof in one direction and for stopping the rotating member at a first and a second positions, and a pair of gripping members attached to the rotating device and being capable of gripping and releasing said vessel. The gripping members are designed to stop at a gripping stop position where said gripping members can grip a vessel in an upright state when said main rotating member stops at the first stop position, and stop at a reversal stop position where said vessel is held in a nearly inverted state when said main rotating member stops at the second positions. The apparatus further comprises a reversal stop position regulating device for regulating said reversal stop position, an empty vessel carrying-out device provided at an empty vessel discharging position on the way along which said gripping members returns from said reversal stop position to said gripping stop position, said empty vessel carrying-out device receiving an empty vessel and transferring it to downstream process; and a gripping member opening / closing apparatus for making said gripping members close to grip a vessel and for making said gripping members opens, thereby discharging the empty vessel towards an empty vessel carrying-out device.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a contents-filling vessel reversing apparatus for use in a bag packaging machine, namely an apparatus for reversing a vessel accommodating contents to be filled into a container such as, for example, a packaging bag. More specifically, the present invention relates to a contents-filling vessel reversing apparatus for reversing a vessel accommodating contents to be filled into a container from a upright state to an inverted state, thereby dropping downward and filling the contents into a packaging container disposed underneath, when foods or the like are packaged in the packaging container. The present invention also relates to a contents-filling vessel for accommodating contents to be filled into a packaging container which vessel are suitable for use with the contents-filling vessel reversing apparatus. [0003] 2. Prior Art [0004] In automatic packaging of foods and the like, filling...

AI Technical Summary

Benefits of technology

[0009] The present invention is made in light of the problems with the prior art as mentioned above. The object of the present invention is to present a contents-filling vessel reversing apparatus capable of discharging the contents from the vessel without hitting it against a stopper or the like, thereby preventing generation of noises to realize favorable working environments, and in addition, avoiding breakage of the vessel and preventing entry of fragments of the vessel into the contents to be filled.

[0010] It is another object of the present invention to present a contents-filling vessel reversing apparatus that enables improvement of the processing capability and ensures filling of contents into a packaging container regardless of the type, properties and amount of the contents to be filled.

[0011] Further it is another object of the present invention to present a contents-filling vessel reversing apparatus that does not need so strong gripping force as required in the conventional apparatus and enables improvements of wear and durability of contents-filling vessels used.

Problems solved by technology

Therefore, a big impact noise is generated at hitting, thereby resulting in one of causes responsible for deteriorated working environments.

Further, the vessel may be chipped in part when hitting on the stopper, which may poses a problem that fragments generated are mixed into the packaging container (vessels made of resin are used in many cases).

Although the impact noise is reduced to a certain extent, this attempt is still not deemed satisfactory.

Besides, in the case viscosity of the contents is relatively high, discharging of the contents from the vessel may become imperfect due to the cushioning action of the cushion member.

Although, compared with the above-mentioned two examples, the problems associated with the impact is relaxed, this proposal does not present a perfect solution.

In the result, adhesion of the contents to the side wall of the guide may take place, thereby causing another problem that the contents are not filled surely into the packaging container.

Accordingly, wear of the vessel becomes excessive and durability becomes poor.

Besides, there is a possibility that foreign matters generated by wear are mixed into the contents.
