Description

A pressure measuring device and a blister packaging device having the same

The present invention relates to a pressure measuring device and a blister packing device having the same, and more particularly, to a pressure measuring device used in an automatic blister packing system and a blister packing device having the same.

Recently, the consumption of disposable products, which are convenient to use and packaged in small quantities, is rapidly increasing. Accordingly, the reliability of product packaging can be secured, and the demand for blister packaging, which has a beautiful appearance and is convenient to use, is rapidly increasing. Blister packaging can be used for packaging medicines, food, cosmetics, chemicals, and the like. Blister packaging systems typically include pressing blocks that are closely spaced and spaced apart from each other to pressurize the packaging material.

1 is a view for explaining a blister packaging system. 2 is a view showing a pill packaging product produced by the blister packaging system.

For example, referring to FIGS. 1 and 2 , the blister packaging equipment applied to the automatic packaging of pharmaceuticals produces sheets in the form of blister packaging after each process of forming, bonding, cutting, transferring, and punching is performed. is produced Among them, the adhesion process is a process in which adhesion between packaging materials (Foil, PVC, PVDC, Alu-Alu, etc.) occurs, and is a section in which functions such as product convention protection and confidentiality maintenance are completed. The key process parameters of the blister equipment bonding process are temperature, pressure and production rate. However, in the case of the conventional blister facility, temperature and production speed can adjust the set value and check the output value, whereas the pressure cannot measure and confirm the set value or output value, so it is difficult to use it accurately.

For example, in case of nonconformity in process inspection and visual inspection during operation of blister equipment, the most likely major factor is non-uniformity of sealing pressure. However, there was a problem in that accurate troubleshooting was difficult and verification was impossible due to the absence of means of numerical confirmation of the adhesive pressure, that is, setting and measuring the pressure value in the process.

Specifically, it is necessary to adjust the strength of the adhesive mold pressure when an in-process control (IPC) inconsistency occurs during the operation of the blister facility. However, since there is no quantified indicator of the pressure value in the process, it has to be performed by experience for each operator. Due to this, the degree and method of the adjustment are different, and there is a problem that an objective takeover is impossible. In other words, the pressure balance adjustment depends only on the experience and proficiency of the operator, and there are difficulties in training for new employees.

In addition, in the conventional blister packaging equipment, there was a problem in that the overall accuracy of the measures taken after the pressure adjustment is not guaranteed. For example, when a problem of non-conformity of airtightness occurs, it is possible to investigate only as a phenomenon and has no choice but to conduct a speculative investigation. Even if the adjustment was made, it was impossible to confirm the degree of adjustment, and it was a situation that relied on experience and skill. In other words, it was impossible to clearly verify the situation as it had to work again after confirming it as a phenomenon.

Therefore, the development of a device capable of expressing the corresponding value by measuring the pressure in each process of the blister packaging equipment, particularly the bonding process, is being requested.

It is an object of the present invention to provide a pressure measuring apparatus used in an automatic blister packaging system and a blister packaging apparatus having the same.

For example, as shown in FIG. 12 , the wiring 330 may be arranged up to the side, but the connector may be formed on the side of the wiring 330 itself instead of drawing out the side. That is, by inserting the cable connected to the indicator 500 into the connector, an electrical connection can be established.
