DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic tablet packaging machine, and more particularly, to a heating block capable of efficiently heating a heater block with a single heater, thereby reducing the heater capacity and packaging. It is intended to ensure the vertical and horizontal sealing of the material (medicine package sheet).

[0002]

2. Description of the Related Art Conventionally, there is an automatic tablet packaging machine of this type having a configuration as disclosed in, for example, Japanese Patent Application Laid-Open No. 3-69406.

[0003] Such a conventional automatic tablet packaging machine, in particular,
In the packaging material sealing device for the medicine package sheet after the tablets are put in, the tablet supplied from the tablet supply mechanism in the tablet packaging machine main body is vertically intermittently fed, and the opening part of the continuous folded medicine package sheet is vertically fed. And the horizontal direction corresponding to the open portion side of the packaging material and the vertical direction corresponding to the width direction side thereof are sandwiched and heat-welded by a heat sealing means comprising a heater block and a heater block receiving member. For sealing.

[0004] The heater block constituting the heat sealing means has a first horizontal seal block portion for sealing a portion corresponding to the open side of the medicine package sheet, and a bag-like portion corresponding to the width direction side of the medicine package sheet.

Thus, a heater base is attached with a gap, and a heater is provided in the horizontal seal block.

[0008]

That is, the present invention provides a first horizontal seal block for sealing a portion corresponding to an open portion of a packaging material, and a second seal for sealing a portion corresponding to a width direction of the packaging material in a bag-like manner. The vertical seal block portion is integrally formed in a T-shape with a metal having good heat conductivity, and the first horizontal seal block portion is used as a mounting portion of the heater block, and is made of a metal having poor heat conductivity. Since a heater is provided inside the first horizontal seal block portion with a gap provided on the base, the heat of the first horizontal seal block portion is conducted to the heater base side, making it difficult to escape. Thereby, the heat of the first horizontal seal block is diffused toward the second vertical seal block, and the heating temperature of the second vertical seal block and the heating temperature of the first horizontal seal block are reduced. Almost the same uniform temperature It is possible to lifting, uniform heating is efficiently performed in the heater block of a single heater.

Further, since a gap is provided between the mounting portion of the heater block and the heater base, the heater capacity can be reduced and the power saving efficiency can be increased.

As is apparent from the above description, according to the present invention, the horizontal seal block portion for sealing the opening portion side portion of the packaging material and the width direction side portion of the packaging material can be separated in a bag shape. A vertical seal block portion is formed integrally with a metal having good thermal conductivity in a T-shape, and the horizontal seal block portion is used as a mounting portion for the heater block. Since the heater is provided inside the horizontal seal block portion with a gap provided on the base, the heat of the horizontal seal block portion is conducted to the heater base side, so that it is difficult to escape.
The heat of the horizontal seal block is efficiently diffused toward the vertical seal block, and the heating temperature of the vertical seal block and the horizontal seal block can be maintained at substantially the same uniform temperature. It is possible to efficiently perform uniform heating of the heater block with the number of heaters, and
Since the gap is provided between the mounting portion of the heater block and the heater base, the heater capacity can be reduced, and the power saving efficiency can be increased.
