no. 1 approach

[0061] Fig. 1 is a schematic diagram showing a sheet packaging machine 1 according to a first embodiment of the present invention. This packaging machine 1 is a four-row packaging machine that manufactures four packages 500 at a time. This package 500 is constituted by the packaging bag 120 and the sheet to be packaged 152a. Furthermore, the packaging bag 120 is comprised from a pair of packaging material 102a, 102a. In this packaging machine 1, a pair of packaging material rolls 100, 100 and four rolls of sheets to be packaged 150, 150 are employed as packaging equipment.

[0062] The packaging material rolls 100 , 100 each have a reel 101 and a packaging material blank 102 wound on the reel 101 . As shown in FIG. 2 , the packaging material blank 102 is formed by connecting packaging materials 102a in four horizontal rows, and the packaging materials 102a in four horizontal rows are connected together in a longitudinal direction.

[0063] On the other hand, as shown in FIG...

Abstract

The invention provides a chute, apparatus for feeding sheet and sheet wrapper for wrapping sheet of light weight. The apparatus for feeding sheet has a chute. Four grooves are mounted on the chute body of the said chute and these chutes are covered by five covers. Thus, four channels are formed on the chute. Each channel vertically extends towards respectively corresponding to a pair of packing material and forms. Furthermore, each channel is formed in the way that a gap is present between the circumference of sheet to be wrapped and inwall, wherein the sheet to be wrapped starts to fall down in the upright state same with a pair of packing material.

Description

technical field [0001] The present invention relates to a chute, a sheet supply device, and a sheet packaging machine used when feeding sheets to be packaged formed in a sheet shape into a packaging bag with at least an open upper end. Background technique [0002] Conventionally, a packaging machine as shown in Patent Document 1 (Japanese Patent Application Laid-Open No. 2005-59936 ) has been proposed for filling and packaging powder in packaging bags. This packaging machine has: a packaging bag supply device, which supplies the packaging bag with the upper end of the packaging bag in an open state; a powder supply device, which supplies powder into the supplied packaging bag; a heat sealer, which supplies the powder The packaging bag is sealed. [0003] Here, the powder supply device is composed of a supply device that supplies powder into the packaging bag, and a control device that controls the operation of the supply device. Furthermore, the supply device has a hopper...
