Description

  The present invention relates to a cutting method and a cutting mechanism of a dispensing device, and in particular, the tablet sheet in a dispensing device for automatically dispensing a package-type tablet called a PTP (press-through package) tablet sheet into a tablet cassette and having a predetermined shape. It is suitable for the method of cutting and its mechanism.

  Traditionally, pharmacists do dispensing work according to doctors' prescriptions at pharmacies such as hospitals, 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 In addition, the work of dispensing based on a prescription 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 format in which tablets are taken out by breaking the aluminum sheet portion at the bottom 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. The king is transferred to a cutting device, where it is cut into a predetermined shape.

  However, when cutting a fraction of a PTP tablet sheet with this cutting device, after cutting the PTP tablet sheet by lowering the blade, when trying to return to the original position after lifting the blade, Since the blade bites in, the PTP tablet sheet is lifted together with the blade, and there is a problem that trouble occurs when moving to the next operation.

  Therefore, in this cutting apparatus, when cutting a fraction of a PTP tablet sheet, when cutting the PTP tablet sheet by lowering the blade, the retainer driven separately from the blade is used to press the entire PTP tablet sheet. Even when the blade is lifted after the cutting, the retainer is used to press the entire PTP tablet sheet.

Therefore, even if the blade bites into the PTP tablet sheet, the retainer driven separately from the blade prevents the PTP tablet sheet from being lifted together with the blade, which may cause trouble when moving to the next operation. Disappear.

  However, the above-described cutting devices of Patent Documents 1 and 2 have a problem that the retainer is driven separately from the blade, which complicates the device and increases costs. In addition, there is a problem that the installation space for the retainer is required and the apparatus is enlarged.

  The present invention has been made in view of such circumstances, and prevents the PTP tablet sheet from being lifted together with the blade after the PTP tablet sheet is cut without using a retainer driven separately from the blade. It is an object of the present invention to provide a cutting method and a cutting mechanism of a dispensing device that can be used.

  According to a first aspect of the present invention, there is provided a dispensing device that performs a cutting operation of a tablet sheet with a blade attached to the moving member by moving the moving member in a direction of separation with respect to the tablet sheet placed on the base. In the cutting method, a retractable sheet pressing member is attached to the moving member, and when performing the cutting operation of the tablet sheet with the blade, the sheet pressing member is reduced in accordance with the movement of the moving member, When pressing the tablet sheet on the base with the sheet pressing member, when the cutting operation is completed and the blade is returned to the original position, the sheet pressing member expands according to the movement of the moving member, The tablet sheet is kept pressed on the base by the sheet pressing member.

  A second invention is a cutting mechanism of a dispensing device in which a blade for performing a cutting operation of a tablet sheet is attached to a moving member that is movable in a separating direction with respect to the tablet sheet placed on the base. In addition, the retractable sheet pressing member is attached to the moving member, and when the tablet sheet is cut by the blade, the sheet pressing member is contracted in accordance with the movement of the moving member. The sheet pressing member acts to press the tablet sheet onto the base, and when the cutting operation is finished and the blade is returned to the original position, the sheet pressing member is moved according to the movement of the moving member. When the tablet extends, the sheet pressing member acts to hold the tablet sheet on the base. It is intended to.

  According to the first and second inventions, when an elastic sheet pressing member is attached to the moving member that moves the blade in the direction of separation with respect to the tablet sheet, and the tablet sheet is cut with the blade, When the sheet pressing member is reduced in accordance with the movement of the moving member, the tablet sheet is pressed onto the base by the sheet pressing member, and when the cutting operation is completed and the blade is returned to the original position, As the sheet pressing member expands in accordance with the movement of the moving member, the tablet sheet is held on the base by the sheet pressing member, so that the tablet sheet is not lifted together with the blade. Will not interfere with the operation. Accordingly, the cutting operation can be performed quickly, and as a result, the work efficiency is greatly improved.

  In addition, since the retainer driven separately from the blade is not used here, there is no problem that the apparatus becomes complicated and causes an increase in cost, and there is no problem that the installation space for the retainer is unnecessary and the apparatus is enlarged. . As a result, space can be saved with a simple configuration.

  The sheet pressing member is preferably an elastic member that can elastically contact the tablet sheet.

  According to the third aspect of the present invention, the sheet pressing member is an elastic member that can elastically contact the tablet sheet, and thus has a simpler configuration. Examples of the elastic member include a leaf spring, rubber, and sponge.

  As in the invention described in claim 4, it is preferable that the sheet pressing member has a shape capable of pressing the tablet sheet in a predetermined range around the blade.

  According to the invention of claim 4, since the sheet pressing member has a shape capable of pressing the tablet sheet in a predetermined range around the blade, the tablet sheet is not lifted together with the blade. The next operation is not hindered. However, when the medicine in the tablet sheet is included in the predetermined range, the medicine may be pressed by the sheet pressing member, and the medicine may be damaged. Therefore, this type of sheet pressing member can be used for a tablet sheet that does not contain soft chemicals.

  Preferably, the sheet pressing member has a shape capable of pressing between the tablets of the tablet sheet.

  According to the invention of claim 5, since the sheet pressing member has a shape capable of pressing between the tablets of the tablet sheet, the tablet sheet is not lifted together with the blade, and the next operation is hindered. There is no going out. Moreover, in this case, even if the blade is deeply biting into the tablet sheet, the medicine on the tablet sheet is not pressed by the sheet pressing member, and there is no possibility of damaging the medicine. Therefore, this type of sheet pressing member can be used for any tablet sheet containing soft chemicals.

  As in the invention described in claim 6, it is preferable that the sheet pressing member has a free dimension higher than the height of the blade around the blade.

  According to the invention of claim 6, since the sheet pressing member has a free dimension higher than the height of the blade around the blade, the tablet sheet is not lifted together with the blade, and the next operation is performed. There will be no hindrance. In this case, since the medicine of the tablet sheet is not strongly pressed, there is no possibility of damaging the medicine, but it cannot be used when the blade is deeply biting into the tablet sheet. Therefore, this type of sheet pressing member can be used for a thin tablet sheet or the like in which the blade does not penetrate deeply into the tablet sheet.

  According to a seventh aspect of the present invention, as the blade, a vertical blade for cutting in the direction perpendicular to the width direction of the tablet sheet and a horizontal blade for cutting in the width direction of the tablet sheet are separately provided. It is preferable that the sheet pressing member is separately provided at portions corresponding to the vertical blade and the horizontal blade of the moving member.

  According to the invention of claim 7, as the blade, a vertical blade for cutting in the direction perpendicular to the width direction of the tablet sheet and a horizontal blade for cutting in the width direction of the tablet sheet are separately provided. Since the sheet pressing member is separately provided at a portion corresponding to the vertical blade and the horizontal blade of the moving member, both the vertical blade and the horizontal blade are together with the blade. Thus, the tablet sheet is not lifted and the next operation is not hindered. Therefore, in this case, the cutting operation by the vertical blade and the horizontal blade can be performed quickly, and as a result, the working efficiency is further improved.

  According to the first and second inventions, when an elastic sheet pressing member is attached to the moving member that moves the blade in the direction of separation with respect to the tablet sheet, and the tablet sheet is cut with the blade, When the sheet pressing member is reduced in accordance with the movement of the moving member, the tablet sheet is pressed onto the base by the sheet pressing member, and when the cutting operation is completed and the blade is returned to the original position, As the sheet pressing member expands in accordance with the movement of the moving member, the tablet sheet is held on the base by the sheet pressing member, so that the tablet sheet is not lifted together with the blade. Will not interfere with the operation. Accordingly, the cutting operation can be performed quickly, and as a result, the work efficiency is greatly improved.

  In addition, since the retainer driven separately from the blade is not used here, there is no problem that the apparatus becomes complicated and causes an increase in cost, and there is no problem that the installation space for the retainer is unnecessary and the apparatus is enlarged. . As a result, space can be saved with a simple configuration.

Show.

  Here, the detailed structure of the sheet pressing member 745 will be described with reference to FIGS. In addition, since it is the same about the sheet | seat pressing member 755, duplication description is abbreviate | omitted.

  As shown in FIGS. 6 and 7, the sheet pressing members 745 and 755 are tablets (corresponding to medicines) 920 of the PTP tablet sheet 900 as a predetermined range around the vertical upper blade 740 and the horizontal upper blade 750. It has a shape capable of pressing between 920.

  That is, the sheet pressing member 745 is capable of pressing between the tablets 920 and 920 of the PTP tablet sheet 900 on the bottom surface, and has a narrow concave portion 7451 having a hole portion 7451 through which the vertical upper blade 740 can be inserted. Spring portions 7454 and 7454 that extend from the left and right projecting portions 7453 and 7453 of the concave portion 7451 upwardly and contractably in the shape of “<” and “reverse” in a front view, and the spring portions 7454, The upper end of 7454 includes attachment portions 7455 and 7455 for attaching to the lower side of the upper blade attachment member 735.

  Further, the sheet pressing member 755 has a concave portion 7551 having a hole portion 7552 capable of pressing between the tablets 920, 920 of the PTP tablet sheet 900 on the bottom surface and allowing the horizontal upper blade 750 to be inserted on the bottom surface, and the concave portion 7551. Spring portions 7554 and 7554 that extend upward and downward from the left and right overhang portions 7553 and 7553 in a front view in a front view and a top end of the spring portions 7554 and 7554, respectively. It consists of attachment portions 7555 and 7555 attached to the lower side of the upper blade attachment member 735.

  The operations of the vertical upper blade 740 and the sheet pressing member 745 will be schematically described. First, as shown in FIGS. 6 and 7A, at the home position, the attachment portion 7455 is provided below the upper blade attachment member 735, respectively. , 7455 attached to the bottom of the concave portion 7451 connected to the lower ends of the spring portions 7454, 7454 via the left and right overhang portions 7553, 7553. The tip of the vertical upper blade 740 is slightly seen through the hole 7452. Below the vertical upper blade 740, the PTP tablet sheet 900 with its end held by the chuck 430 of the chucking unit 400 is placed on the lower blade attachment member 780.

  Now, the fraction of the PTP tablet sheet 900 to be cut is calculated according to the prescription data by a control device (not shown), and the pulse motor 721 is driven by a predetermined step in response to an operation command signal from a controller (not shown) corresponding to the calculated value. Is done. Thereby, cutting with the vertical upper blade 740 or the horizontal upper blade 750 shall be performed. In this case, when the pulse motor 721 is driven, the drive gear 722 decelerates the driven gear 723 to a predetermined rotational speed and drives the rack 736 via the pinion gears 725 and 725 at the left and right ends of the drive shaft 724. , 736 are pushed down by the same amount.

  Then, the upper blade attaching member 735 is lowered while maintaining a horizontal state, and the vertical upper blade 740 is pushed down simultaneously with the sheet pressing member 745. In this way, the upper blade attaching member 735 is lowered, and first, between the tablets 920 and 920 of the PTP tablet sheet 900 is pressed by the bottom surface of the concave portion 746, the vertical upper blade 740 that is inserted through the hole portion 7452 of the bottom surface. Therefore, the PTP tablet sheet 900 shall be cut. At this time, as shown in FIG. 7B, the spring portions 7454 and 7454 attached by the attachment portions 7455 and 7455 are contracted to the lower side of the upper blade attachment member 735, respectively. , 7454 protrudes from the hole portion 7451 on the bottom surface of the concave portion 7451 connected to the lower end of the left and right overhang portions 7453, 7453, and deeply bites into the PTP tablet sheet 900.

  When the vertical upper blade 740 has finished cutting the PTP tablet sheet 900, it receives an operation command signal from a controller (not shown) again, and the pulse motor 721 is driven in the opposite direction by a predetermined step. As a result, the upper blade attaching member 735 is raised to return the vertical upper blade 740 to its original position. In this case, when the pulse motor 721 is driven, the drive gear 722 drives the driven gear 723 to a predetermined value. And the racks 736 and 736 are pushed up by the same amount via the pinion gears 725 and 725 on the left and right ends of the drive shaft 724.

  Then, the upper blade attaching member 735 is raised while maintaining a horizontal state, and the vertical upper blade 740 is pushed up, but the sheet pressing member 745 does not follow this operation.

  That is, at this time, the spring portions 7454 and 7454 attached to the lower blade attachment member 735 with the attachment portions 7455 and 7455 respectively start to expand, and the left and right overhang portions 7453 at the lower ends of the spring portions 7454 and 7454 Since the bottom surface of the concave portion 7451 connected to 7453 is still in contact with the PTP tablet sheet 900, the tip of the vertical upper blade 740 can easily come out of the PTP tablet sheet 900.

  The above is the same for the operations of the horizontal upper blade 750 and the sheet pressing member 755.

  According to this type of sheet pressing members 745 and 755, the PTP tablet sheet 900 has a shape capable of pressing between the tablets 920 and 920, and therefore the vertical upper blade 740 and the horizontal upper blade 750 are cut after the PTP tablet sheet 900 is cut off. The PTP tablet sheet 900 is not lifted together with this, and the next operation is not hindered. In addition, in this case, even if the vertical upper blade 740 or the horizontal upper blade 750 is deeply biting into the PTP tablet sheet 900, the chemical of the PTP tablet sheet 900 is not pressed down, so that the chemical may be damaged. There is no. Therefore, this type of sheet pressing member 745, 755 can be used for any PTP tablet sheet 900 containing soft chemicals.
