Description

The present invention relates to a cassette fixing structure of a dispensing device, and in particular, the tablet cassette is fixed to a cassette shelf of a dispensing device that automatically dispenses a packaged tablet called a PTP ( press- through package) tablet sheet into a tablet cassette. It is suitable for the structure to do.

  Traditionally, pharmacists perform dispensing work in pharmacies such as hospitals according to doctors' prescriptions, but in general hospitals where medical fields are wide, there are many types of tablets that can be taken out at all times, and storage locations are limited. Not only was it necessary, but the work of dispensing based on prescriptions was very mentally and physically burdensome.

  Therefore, a dispensing device has been developed that automatically dispenses a predetermined number of predetermined tablets including a fraction of a PTP tablet sheet based on a preset program (see, for example, Patent Documents 1 and 2). The PTP tablet sheet is a packaging form in which the tablet is taken out by breaking the bottom aluminum sheet part by pressing the tablet side. Generally, 10 or more tablets are made into one sheet. Supplied.

  Here, the tablet cassette in which a plurality of PTP tablet sheets are placed is housed in a cassette shelf, and the claw portion of the chucking device mounted on the head device is directly in the groove formed on the front surface of the tablet cassette. Intrusion and relative positioning are performed, and the PTP tablet sheet at the lowest position in the tablet cassette is chucked and taken out to the outside.

  In this tablet cassette 1000, as shown in FIG. 11, a stopper 1100 having a circular flange is hooked at a semicircular portion so that one stopper can be used for two. A pair of knurled screws 1200 are provided on the opposite side to the stopper 1100, and the knurled screws 1200 are screwed into a female screw 1500 of a fixed bar 1400 that also serves as a reinforcement fixed to the cassette shelf 1300. Both ends of the tablet cassette 1000 are fixed to the cassette shelf 1300.

Here, PTP tablet sheets (not shown) have various outer shapes, and a pair of width regulating members 1011 are provided on the inner side of the outer wall body 1010 of the tablet cassette 1000 in order to regulate and accommodate these outer shapes. ing. These width regulating members 1011 are fixed by screws 1040 inserted through the long holes 1030 drilled in the front wall body 1020, and after loosening these screws 1040, the width regulating members 1011 are attached to the PTP tablet sheet. The width direction of all PTP tablet sheets can be regulated by providing a gap in the width dimension and fixing it.
