Description

TECHNICAL FIELD The present invention relates to a manufacturing apparatus for forming a bag body from a roll-shaped sheet and printing character information on the surface thereof to form a medicine bag.

[Conventional technology]

Usually, the medicine bag delivered from the pharmacy of the hospital describes the usage of the medicine, the patient name, precautions, etc. based on the contents of the prescription issued by the doctor, and this description identifies the patient and how to use it. It is designed to communicate.

Since such a medicine bag usually accommodates 1 to 2 kinds of medicines, when one patient is given several kinds of medicines, it is necessary to prepare a plurality of medicine bags corresponding to the number of medicines. is there.

As a medicine bag which has been generally used from the past, as shown in FIG.
As shown in FIG. 19, there is a heat-sealed sheet having two sides on the outer circumference, which are formed of heat-fusible sheets having different shapes.

That is, the one shown in FIG. 18 is formed by heat-sealing a cylindrically shaped sheet S in the width direction and then cutting along the sealing portion, and the one shown in FIG. 19 is a sheet S folded in two. After being heat-sealed at two positions in the width direction, the seal portion is cut at two equal positions.

Conventionally, in order to efficiently perform the above-mentioned forming of the medicine bag and the operation of writing the characters, it is possible to simultaneously form several different kinds of medicine bags from the roll-shaped heat-fusible sheet and print the character information on the surface of the medicine bag. The present applicant has proposed such a device (Japanese Patent Application No. 1-151473).

This proposed apparatus has a plurality of medicine bag printing units provided with a heater device, a cutter device, a printing device, and the like arranged along the conveyance path of the heat-fusible sheet, and is provided with a plurality of medicine bag printing units. The printing process can be performed simultaneously.

[Problems to be Solved by the Invention]

By the way, the information such as the patient name and the usage of medicines printed on the surface of the medicine bag is often written on the surface of the medicine bag in plural lines in different lines. In order to perform such printing, a conventional printing device includes a feed mechanism that moves a bag body by a predetermined distance along a sheet conveying path, and a printer head that moves in a direction perpendicular to the feed mechanism and prints characters. By combining the movements of the two, the character information is printed on a plurality of lines.

However, in the above-described structure, the degree of difficulty in the printing process is significantly different depending on the relationship between the ejection direction of the printer head and the direction of the bag fed into the printing device.

That is, in the case of the medicine bag shown in FIG. 18, the sealing direction is orthogonal to the transport direction (a), and the arrangement direction of the characters on the surface and the moving direction of the printer head (b) are parallel, so the printer head After typing out the characters in each line by
A line feed can be performed by the feeding mechanism, and printing work can be performed according to the movement of sheet conveyance.

On the other hand, in the case of the medicine bag shown in FIG. 19, the sealing direction is parallel to the transport direction (a), and when it is sent to the printing device as it is, the arrangement direction of the characters horizontally written on the surface and the moving direction of the printer head ( B) becomes a right angle. For this,
In order to print the character information, it is necessary to re-edit the array of characters to be printed by the printer head, and there is a problem that the printing operation takes a long time. In particular, when printing characters on a medicine bag in different colors for each line, it is necessary to move the coloring ribbon or change the coloring liquid each time the printer head is moved by one character. However, there is a drawback that the work takes a significant amount of time.

In order to deal with the above problems, when forming the medicine bag shown in FIG. 19, the conveying direction of the folded sheet is changed to a right angle at the feeding position to the printing device, and the character arrangement direction and the printing device are changed. A structure is considered in which the launch directions of are parallel.

However, in such a structure for changing the sheet conveyance direction, the area occupied by the conveyance path in the horizontal plane becomes large, the apparatus becomes large, and the mechanism for changing the conveyance direction is
Since the structure of the transport path is complicated, the manufacturing cost is increased.

In addition, the above devices are vertically stacked to form a tubular sheet and a tubular sheet.
When forming different kinds of medicine bags from the folded sheet, there is a problem that the installation space becomes large because it is necessary to provide the roll body and its indicating member in two directions orthogonal to the apparatus.

The present invention has been made in view of the above problems,
A first object of the invention is to provide a manufacturing apparatus capable of efficiently forming a medicine bag and performing a printing process with a simple structure without changing the sheet conveying direction.
