Embodiment Construction

[0032] Hereinafter, the pocket opening method and apparatus according to the embodiment of the present invention will be described with reference to the drawings.

[0033] figure 1 It is a schematic perspective view showing the overall structure of an intermittent rotary rotary bag-sealer (hereinafter simply referred to as "packer") 1 using the pocket opening device 6 according to the first embodiment of the present invention. In addition, an intermittent rotary type rotary bagging and packaging machine will be described below as an example, but the packaging machine to which the present invention is applied is not limited thereto. That is, the posture of the bag held by the jig may be a vertical posture or a horizontal posture. In addition, the transfer of bags is not limited to intermittent transfer, and may be continuous transfer. In addition, the transfer track of the bags may be arc-shaped, straight-line, or track-shaped.

Abstract

The utility model provides a pocket mouth opening method and opening apparatus which is simple in structure, can open a pocket mouth reliably and stably, and does not damage the pocket mouth or letting any foreign mater go into the pocket, etc. Gas is ejected toward the pocket mouth of a pocket (B) from a gas ejecting nozzle (27) so as to separate the closed pocket mouth. By his time, a pair of plate-shaped pouring prevention mechanisms (21, 21) which are configured to be mutually opposite at a narrow interval are used for preventing the pocket mouth from shaking or pouring. After a prepared opening procedure being implemented, a pair of adsorption mechanisms which are mutually connected and separated are used for executing the opening procedure.

Description

technical field [0001] The present invention relates to an opening method and an opening device for opening the mouth of a bag. More specifically, it involves holding the side edges of a bag by a pair of left and right grippers that can be freely connected to and detached from each other, and while transferring the bag along a predetermined movement track in a horizontal plane, the opening of the bag opening and the packaged object are sequentially carried out. The opening method and opening device of the bag opening in the bagging package specified in the packaging process such as the filling of the bag opening and the sealing of the bag mouth. Background technique [0002] As the device for opening the mouth of the bag in the above-mentioned bagged package, as disclosed in Japanese Patent No. 2587946, it is known that a pair of suction cups are adsorbed to both side surfaces of the bag, and the mouth of the bag is opened by keeping the suction cups away from each other. A...
