Specification

Heating element folding device

Technical field

[0001] The present invention relates to a device for folding a heating element by folding guide means for folding a folding part of the heating element that is conveyed while being stacked on the surface of the conveying means by a folding support means.

Background art

[0002] The exothermic agent accommodating portion is divided by a substantially straight intermediate seal portion formed in the approximate center, and each exothermic agent accommodating portion bulges toward the breathable sheet with respect to the non-breathable sheet. The body of the warmer formed in a protruding shape is provided with a release layer on one side of the packaging sheet, and the packaging sheet is mounted so as to be superimposed on the adhesive layer formed on the release layer. The folding roll is sandwiched between the folding guide plate and the folding transport belt in a state where the folding half is overlapped with the fixed half side, and is pulled downstream with a predetermined tension by the press belt. The side moves relative to the intermediate seal part of the body warmer, the folding half surface side rises along the intermediate seal part in a valley fold shape, and folds along the intermediate seal part of the body warmer. Patent Document 1 discloses a method of sealing in a bag shape by sealing edges that face each other at the peripheral edge except for the bent portion in a state where the release layer is in close contact with the outside of the adhesive layer. Has been.

[0003] However, in Patent Document 1, an adhesive layer is formed on the release layer on the side of the packaging sheet, and the body body is attached so as to overlap the adhesive layer. This is a folding device that can be applied only to force iro, and was a folding method.

Usually, a pressure-sensitive adhesive layer is formed on the side of the body that is generally used, and is attached to a non-breathable packaging sheet, that is, a pressure-sensitive adhesive layer with a separator is attached to an outer bag that is a non-breathable storage bag. The force that cannot be applied to the folding of the heating element provided.

In addition, it is an essential condition that the body is fixed to the adhesive layer provided on the outer bag. For this reason, it was difficult to apply to a heating element that is not fixed to the outer bag via an adhesive layer. In addition to the case where the outer bag is provided with a pressure-sensitive adhesive layer as a warmer fixing layer when using a warmer, there are three or more divided heat generating portions except when the warmer is fixed to the pressure-sensitive adhesive layer. In the case of a heating element, it was bent between each section heating part, and the rise of the valley fold did not start well along the intermediate seal part of the body of the warmer by the presser roll, and there was a problem with the folding.

Another problem is that the folding finish is unstable and defective products tend to occur.

If it is less than 0.01, the moldability will deteriorate, and if it exceeds 14, the heat generation characteristics will deteriorate.

[0058] The mobile water value is a value indicating the amount of excess water that can move out of the exothermic composition in the water present in the exothermic composition. This easy water value will be explained.

Center point force No. 2 QIS P 3801 (Type 2) with 8 lines radially written at 45 degree intervals) is placed on a stainless steel plate, and the center of the filter paper has an inner diameter of 20 mm and a height of 8 mm. Place a template with a hollow cylindrical hole length 150mm X width 100mm, place a sample near the hollow cylindrical hole, move the push plate along the mold plate, and push the sample into the hollow cylindrical shape Into the hole and scrape the sample along the mold surface (indentation molding).

Then, the filter paper is taken out, and the soaking locus of water or aqueous solution is read in mm units as the distance from the circumferential portion that is the edge of the hole of the hollow cylinder to the soaking tip along the radial line. Similarly, the distance is read from each line to obtain a total of 8 values. Each of the 8 values read (a , b, c, d, e, f, g, h) are measured moisture values. The arithmetic mean of the 8 measured moisture values is the moisture value (mm) of the sample.
