Description

  The present invention relates to a device for detecting a pocket position of a tablet sheet, and is particularly suitable for a device for detecting a pocket position of a tablet in a packaging format called a PTP (press-through package) tablet sheet.

  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 on which the PTP tablet sheet is placed is accommodated in the cassette shelf, and the claw portion of the chucking device mounted on the head device chucks the PTP tablet sheet at the lowest position in the tablet cassette. It is king and transported to a cutting device, where it is cut into a predetermined shape. The cut piece is paid out to the tray, while the remaining fraction sheet is returned to the tablet cassette.

In Only in and a guide operation command unit 33 for outputting.

  The control device 20 is configured by a general-purpose or dedicated computer that is arranged close to the dispensing device 1, and includes a ROM 21, a RAM 22, a display unit 23, an input unit 24, a CPU 25, and a storage unit 30. . The ROM 21 stores a control program for the pocket position detection apparatus 1000, various preset data, and the like, and the RAM 22 temporarily stores data. The display unit 23 is composed of an LCD or the like, and displays various messages to the user such as an occurrence report of a cut mistake. The input unit 24 is for inputting various instructions of the user.

  The storage unit 30 stores a pocket position of the PTP tablet sheets 900, 900,... Stacked in the tablet cassette 500 in advance (corresponding to a pocket position storage unit), and the PTP tablet sheet 900. , 900,..., An area (corresponding to an ear part size storage unit) that stores in advance the dimensions of the ear part 930 for chucking with the chuck 430 of the chucking unit 400. The storage unit 30 may be provided outside the control device 20 or on the controller 10 side.

  The CPU 25 controls the overall operation of the pocket position detection apparatus 1000 via the controller 10 in accordance with a control program stored in advance in the ROM 21. When the pocket position relative to the position is different from the pocket position stored in the storage unit 30, the correction means 25 a that corrects the pocket position stored in the storage unit 30 using the “deviation” that is the difference between the pocket positions. Further, when the “deviation” is larger than the size of the ear 930 stored in the storage unit 30, the erroneous filling determination means 25b for determining that the direction of filling into the tablet cassette 500 is incorrect, and the tablet cassette 500. When it is determined that the direction of filling is wrong, the PTP tablet sheet by the cutting unit 700 00 of the cutting operation and a prohibition means 25c to prohibit.

  The schematic operation of the pocket position detection apparatus 1000 will be described below with reference to FIG. The storage unit 30 stores in advance a distance from the sheet end surface detection sensor 1020 ON (or OFF) to the sheet sensor 1030 ON (or OFF) (hereinafter referred to as a seat pocket position) as a parameter. At the same time, the dimension data of the ear portion 930 of the PTP tablet sheet 900 is stored (step S1).

  Then, after the power is turned on, in response to a signal from the CPU 25, the chucking operation command unit 31 outputs an operation command signal. Upon receiving this operation command signal, the chucking unit 400 chucks the lowermost PTP tablet sheet 900 from the tablet cassette 500 by the chuck 430 and takes it out (step S2).

  The guide operation command unit 33 outputs an operation command signal. Receiving this operation command signal, the guide 1010 moves the left and right spring portions 1015 in the sheet width direction (step S3).

  The chucking operation command unit 31 outputs an operation command signal. Upon receiving this operation command signal, the chucking unit 400 detects the sheet end surface position of the PTP tablet sheet 900 chucked by the chuck 430 and taken out to the outside using the sheet end surface detection sensor 1020 (step S4).

  The PTP tablet sheet 900 is further pushed into the guide 1010 by the parameter corresponding to the sheet pocket position stored in the storage unit 30 (step S5).

  When the sheet sensor 1030 is ON (or OFF), the PTP tablet sheet 900 is pulled into the guide 1010 by 0.1 to 0.5 mm, for example, until the sheet sensor 1030 is OFF (or ON), and the sheet detected this time The pocket position is stored in the storage unit 30 (step S6). Or, conversely, when the sheet sensor 1030 is OFF (or ON), the PTP tablet sheet 900 is further pushed into the guide 1010 until the sheet sensor 1030 is ON (or OFF).

  The sheet pocket position of the PTP tablet sheet 900 of this time is compared with the sheet pocket position stored in the storage unit 30, and a “deviation” that is the difference between both pocket positions is calculated by the correction means 25 a, and the storage unit 30 (step S7).

  The erroneous filling determination unit 25b determines whether or not the “deviation” stored in the storage unit 30 is larger than the ear size (step S8). If the “deviation” stored in the storage unit 30 is larger than the ear size (YES in step S8), the PTP tablet sheet 900 is filled in the tablet cassette 500 with the wrong orientation ( The prohibiting means 25c returns to step S2, forcibly withdraws the PTP tablet sheet 900 without entering the cutting operation by the cutting unit 700 (step S9), and again from the tablet cassette 500. The tablet sheet 900 is taken out.

  When the “deviation” stored in the storage unit 30 is smaller than the ear size (NO in step S8), the erroneous filling determination unit 25b places the PTP tablet sheet 900 in the tablet cassette 500 in the correct orientation. It is considered that the material has been filled, the offset is offset to the cut coordinates by the “deviation”, the cutting operation is performed by the cutting unit 700 (step S10), and the process returns to step S2. At the next take-out, “shift” is detected by comparison with the previous seat pocket position. This is repeated and the “deviation” stored in the storage unit 30 is updated each time. Note that the routine can be exited by turning off the power.

  According to the pocket position detection apparatus 1000 of the first embodiment, the pocket position of the PTP tablet sheet 900 loaded in the tablet cassette 500 is stored in the storage unit 30 in advance, and the leading end of the PTP tablet sheet 900 guided by the guide 1010 is stored. The position is detected, the pocket position with respect to the detected front end position of the PTP tablet sheet 900 is detected, and the detected pocket position with respect to the front end position of the PTP tablet sheet 900 is the pocket position stored in the storage unit 30. When they are different, the pocket position stored in the storage unit 30 is corrected by using the “deviation” which is the difference between the two pocket positions. Therefore, the pocket position stored in the storage unit 30 is read out, The correct pocket position of the tablet sheet can be obtained.

  Further, since this pocket position is automatically obtained, it takes less time and labor compared to the case where the conventional scale is directly applied to the PTP tablet sheet 900, and the measurement position varies due to variations in the measurement angle. It becomes difficult to occur. Therefore, an accurate measurement position is always obtained regardless of the skill level of the measurer. Then, accurate cutting of the PTP tablet sheet 900 is performed by the cutting unit 700 of the dispensing device 1 that has input data in which the pocket position stored in the storage unit 30 is corrected by “deviation”. Thereby, there is no possibility of cutting the pocket 920 of the PTP tablet sheet 900, and chemicals are not wasted.
