Description

[0001] The present invention relates to a packing module for a drug packing apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging module employed in a pharmaceutical packaging apparatus capable of automatically preparing and packaging medicines according to prescriptions.

In recent years, a pharmaceutical packaging apparatus has been proposed in order to solve the problems caused by manual packaging of pharmacists. Typically, a pharmaceutical packaging apparatus has a plurality of pharmaceutical cartridges arranged in a multi-stage arrangement on top thereof, and various types of medicines are contained in the pharmaceutical cartridges. The medicines contained in the medicament cartridges are selected according to the prescription signal by the computer operation of the user and discharged from the medicament cartridges one by one. Then, when the discharged medicines are collected in the hopper and fall, they are packed in a packaging module installed in the lower space of the medicament packing apparatus.

Generally, the packaging module is configured to package medicines in a wrapper by the following process. The medicines discharged from the hopper are put into the wrapping paper conveyed to the lower side of the hopper one by one. At this time, the wrapping paper is folded in half by the triangular plate so as to open from the lower side to the upper side of the hopper. Then, the medicines are put into the wrapping paper in a dose amount through the upper opening of the wrapping paper. The medicines are supplied to the sealing mechanism for sealing in the state of being put in the wrapping paper. At this time, the sealing mechanism seals the upper opening of the wrapping paper and continuously seals the contents one time at a time. The medicine packages sealed with the medicines are guided by the take-out rollers, conveyed to the conveyor through the cutter, and discharged to the outside by the conveyor. At this time, the cutter can cut the paper by one day or several days.

On the other hand, the wrapping paper is transported in a sloping manner to the lower side of the hopper in the process of folding the wrapper in a half width so that the upper part is opened by the triangular plate, and the slurry is fed into the sealing mechanism by feeding the drugs from the hopper. Thereafter, the jar which is hermetically packed with the medicines via the sealing mechanism is guided by the take-out rollers in the inclined state, and is transported toward the cutter. At this time, the take-out rollers convey the papers with the upper sealing portion of the pouches so that the medicines packed in the pouches are not damaged.

However, the pouches which have been subjected to the sealing mechanism have not easily entered through the take-out rollers or have been separated from the take-out rollers due to causes such as loads of packaged drugs. In this state, there is a problem that packaging mistakes are caused by drying between the sealing mechanism and the take-out rollers as the paper is continuously conveyed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a front view showing an example of a medicine packing apparatus in which a packaging module according to an embodiment of the present invention is installed.

Referring to FIG. 1, when a doctor makes a prescription by a computer operation, the medicine packing apparatus 10 selects and discharges the medicines from the plurality of medicament cartridges 11 in accordance with the prescription signal. When the discharged medicines are gathered by the hopper 12 through the discharge passage and fall down, the medicament packing apparatus 10 is moved from the lower side of the hopper 12 to the packaging module 100 according to the embodiment of the present invention Packed by.

Fig. 2 is a front view of the packaging module shown in Fig. Figure 3 is a perspective view of Figure 2;

2 and 3, the packaging module 100 includes a wrapping paper supply mechanism 110, a folding member 120, a sealing mechanism 130, a cutter 140, take-out rollers 150, And a drug delivery detection unit 160.

The wrapping paper supply mechanism 110 supplies the wrapping paper P toward the hopper 12 of the medicine packing apparatus 10. [ For example, the wrapping paper supply mechanism 110 includes a wrapping paper supply roll 111 wound with a wrapping paper P and a plurality of wrapping paper guide rolls 112 for guiding the transfer of the wrapping paper P to the drug insertion position . The wrapping paper supply mechanism 110 can supply the wrapping paper P with both wide sides facing up and down. The wrapping paper P is brought into thermal contact with the print ribbon R by the printer 101 before the wrapping paper P is fed to the medicine feeding device by the wrapping paper feeding mechanism 110 so that various kinds of time, Bibliographies can be printed.

The folding member 120 receives the wrapping paper P from the wrapping paper feeding mechanism 110 and folds the width of the wrapping paper P in half so that the upper portion of the wrapping paper P is opened from the lower side of the hopper 12. [ The bending member 120 may be formed of a triangular plate. In this case, the triangular plate is arranged so that the wrapping paper P is folded in a substantially V-shape.

The sealing mechanism 130 receives the wrapping paper P having the dosing doses of the medicines from the hopper 12 via the bending member 120 to seal the upper opening and continuously seals the medicines one by one do. The sealing mechanism 130 may include a pair of heating rollers and a rotation driving unit for rotating the heating rollers.

The heating rollers rotate by the rotation drive unit with the wrapping paper P inserted therebetween. Each of the heating rollers may include first and second sealing portions. The first sealing portions of the heating rollers continuously rotate in engagement with each other to heat the wrapping paper P to seal the upper opening of the wrapping paper P. [ The second sealing portions of the heating rollers are intermittently engaged with each other in a unit of one set amount corresponding to the set dosing amount, and heat is applied to the wrapping paper P to seal the wrapping paper P one by one. The first sealing portions of the heating rollers may provide a conveying force to the wrapping paper P.

The cutter 140 receives the paper P 'wrapped with the medicines from the sealing mechanism 130 and cuts the cut paper into a predetermined amount. For example, the cutter 140 can cut the paper P 'for one day or several days.

The take-out rollers 150 guide the transfer of the paper P 'from the sealing mechanism 130 to the cutter 140. The take-out rollers 150 can transfer the paper P 'to the cutter 140 by interposing the upper sealing portion of the paper P' so that the medicines packed in the paper P 'are not damaged. The take-out rollers 150 may be rotated by being supplied with power from a rotation driving unit for rotating the heating rollers, or rotated by receiving power from a separate driving unit. The take-out rollers 150 can rotate at the same speed as the heating rollers.

The drug delivery sensor 160 senses whether the drug P 'is transferred between the take-out rollers 150 and the cutter 140. The drug delivery detection unit 160 is disposed between the take-out rollers 150 and the cutter 140. For example, the drug delivery sensor 160 may be an ultrasonic sensor to sense the drug P 'even if the drug P' is made of a transparent material.

The ultrasonic sensor includes a transmitter for transmitting ultrasonic waves and a receiver for receiving ultrasonic waves. It is possible to detect the presence or absence of the pouch P 'according to whether or not the ultrasonic wave transmitted from the transmitter is reflected by the pouch P' and is received by the receiver. The transmitter and the receiver may be disposed toward one side of the foam P '. In this case, if the paper P 'is transferred between the take-out rollers 150 and the cutter 140, the receiving unit receives ultrasonic waves transmitted from the transmitting unit. When the receiving unit receives the ultrasonic wave, the ultrasonic sensor senses that the paper P 'is conveyed between the take-out rollers 150 and the cutter 140.

As another example, the transmitter and the receiver may be disposed facing each other with the pouch P 'therebetween. In this case, if the paper P 'is transferred between the take-out rollers 150 and the cutter 140, the receiving unit can not receive ultrasonic waves transmitted from the transmitting unit. When the receiving unit does not receive ultrasonic waves, the ultrasonic sensor senses that the paper P 'is transferred between the take-out rollers 150 and the cutter 140.

The information sensed by the drug delivery detection unit 160 may be provided to the control unit 102. The control unit 102 determines that the package P is not sensed between the take-out rollers 150 and the cutter 140 based on the information sensed by the package conveyance sensing unit 160, It is possible to stop the packaging operation. The control unit 102 may stop the packaging operation of the packaging module 100 and then display an error message through the display unit or the like.

As described above, when the packaging module 100 senses that the paper P 'is not conveyed between the take-out rollers 150 and the cutter 140 by the paper transport detecting unit 160, the packaging operation is stopped do. Accordingly, since the paper P 'does not enter between the take-out rollers 150 or is continuously conveyed while being separated from the take-out rollers 150, the gap between the seal mechanism 130 and the take- Can be prevented in advance. Thereafter, the operator can repair the packaging module 100, thereby enabling normal packaging.

Meanwhile, the packaging module 100 may include a papermaking detection unit 170 for detecting whether or not the papermaking sheet P 'is cut by the cutter 140. The information sensed by the papermaking severing unit 170 may be provided to the control unit 102. The control unit 102 displays an error message through the display unit or the like on the basis of the information detected by the detection unit 170 when it is determined that the drug P ' Alternatively, the cutter 140 can cut the paper P 'again. The papermaking detection unit 170 may include an ultrasonic sensor in the same manner as the papermaking detection unit 160. In this case, the transmitting unit and the receiving unit of the ultrasonic sensor may be disposed toward one side of the foam P 'or disposed opposite to each other with the foam P' interposed therebetween.

4 and 5, the cutter 140 includes a frame body 1410, a support block 1420, a cutter blade 1430, and a linear drive 1440 .

The frame body 1410 can be fixed to the drug packaging apparatus 10. The support block 1420 is mounted to the frame body 1410. The cutter blade 1430 is arranged to pass the medicament-wrapped medicament P 'between the support block 1420 and the spaced apart. The cutter blade 1430 linearly moves toward the support block 1420 and cuts the paper P 'as it crosses the support block 1420. [ Therefore, since the entire width of the portion to be cut of the drug P 'can be cut more quickly, the portion to be cut of the drug P' can be cut accurately without breaking.

The cutter blade 1430 can be mounted on the cutter blade mounting block 1431 and supported. The cutter blade mounting block 1431 can be guided in linear motion by the guide portion. The guide portion may include two guide rods 1432. The guide rods 1432 are fixed to the frame body 1410 at both ends through the cutter blade mounting block 1431 along the linear movement direction of the common mounting block 1431. [

The cutter blade mounting block 1431 may be arranged to face the support block 1420 and move linearly to be close or spaced relative to the support block 1420. In this case, a jig 1433 and an elastic member 1434 for a jig may be provided on the cutter blade mounting block 1431. [ The jig 1433 is supported on the cutter blade mounting block 1431 so as to be linearly movable toward the opposite side of the support block 1420 while being projected toward the support block 1420 rather than the cutter blade 1430. In addition, the jig 1433 is arranged to contact or separate from the support block 1420 in accordance with the linear movement of the cutter blade mounting block 1431. The elastic member 1434 for jig applies an elastic force to the jig 1433 in a direction in which the jig 1433 protrudes toward the support block 1420. [

The jig 1433 and the elastic member 1434 for a jig can act as follows. Before the cutter blade 1430 crosses the support block 1420, the jig 1433 is contacted with the support block 1420 via the paper P '. Thereafter, when the cutter blade 1430 linearly moves while crossing the support block 1420, the jig 1433 receives the elastic force of the elastic member 1434 for the jig and moves the support block 1420 through the pouch P ' And moves linearly to the opposite side of the support block 1420. [ Accordingly, the paper P 'is held by the jig 1433 and the support block 1420 before being cut by the cutter blade 1430 until the cutting is completed. Therefore, the cutting process of the paper P 'can be more stably performed.

The support block 1420 is linearly guided by the guide rods 1432 and can be linearly moved by the linear driving part 1440 so as to be close to or spaced from each other at the same time as the cutter blade mounting block 1431. The jig 1433 of the cutter blade mounting block 1431 and the support block 1420 simultaneously support both sides of the foam P 'while approaching the foam P', and in this state, the cutter blade 1430 And the support block 1420 intersect at the same time, the cutting of the paper P 'can be performed. Accordingly, the drug P ' can be cut more quickly, with motion being minimized and more precisely cutable.

The linear driving part 1440 linearly moves the cutter blade mounting block 1431. The linear driving part 1440 may include first and second rack gears 1441a and 1441b, a pinion gear 1441c and an actuator 1442. [

The first rack gear 1441a is fixed to the cutter blade mounting block 1431 and linearly moves together with the cutter blade mounting block 1431. [ The second rack gear 1441b is fixed to the support block 1420 and linearly moves with the support block 1420. [ The pinion gear 1441c is rotatably supported by the frame body 1410. [ The pinion gear 1441c meshes with the first and second rack gears 1441a and 1441b between the first rack gear 1441a and the second rack gear 1441b. The actuator 1442 linearly moves either the first rack gear 1441a or the second rack gear 1441b. Accordingly, the cutter blade mounting block 1431 and the support block 1420 can simultaneously be close to or spaced from each other.

The actuator 1442 may include a rotation motor 1443, a cam 1444, a movable bar 1445, an elastic member 1446 for a movable bar, and a sensor bar 1447 for a movable bar.

The body of the rotary motor 1443 is fixed to the frame body 1410. The cam 1444 is eccentrically fixed to the rotary shaft 1443a of the rotary motor 1443. [ The cam 1444 may have various shapes such as a circular plate or the like.

The movable bar 1445 may be mounted on either the first rack gear 1441a or the second rack gear 1441b and be in contact with the cam 1444. [ The movable bar 1445 can intersect the cutter blade 1430 and the support block 1420 while moving in contact with the longest portion of the cam 1444. The movable bar 1445 can separate the jig 1433 and the support block 1420 from each other while moving in contact with the shortest portion of the cam 1444. [

The elastic member 1446 for the movable bar keeps the movable bar 1445 in contact with the cam 1444 by an elastic force. Accordingly, the movable bar 1445 can move linearly in accordance with the rotation of the cam 1444, so that the cutter blade mounting block 1431 and the support block 1420 can be close to or spaced from each other. For example, the elastic member 1446 for the movable bar is made of at least one tension coil spring, and both ends of the tension coil spring can be fixed to the cutter blade mounting block 1431 and the frame body 1410 adjacent thereto.

The movable bar sensor unit 1447 detects the position of the movable bar 1445 and allows the operator to check whether the cutter blade 1430 is in the set cutting position. The movable bar 1445 includes the sensor dog 1445a, and the sensor bar 1447 for the movable bar may include the optical sensor unit. The movable bar sensor 1447 can sense the position of the movable bar 1445 by sensing whether the sensor dog 1445a enters the sensing position.

Information sensed by the movable bar sensor unit 1447 may be provided to the control unit 102. The control unit 102 can determine whether or not the cutter blade 1430 is at the set cutting position based on the information sensed by the movable bar sensor unit 1447. [ The control unit 102 controls the rotation motor 1443 to rotate the cam 1444 by 180 degrees on the basis of the set cutting position of the cutter blade 1430 sensed by the sensor unit 1447 for the movable bar.
