Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a packaged medicine in a medicine packing machine,
The present invention relates to a carrying-out device for a sachet that can be reasonably sent out from a packaging position in a narrow space.

(Background of the Invention) A medicine packing machine used for packing dispensing medicines in pharmacies in hospitals, clinics, etc., naturally has a large device size and a proportional installation space when its capacity is large. Grows. However, due to the rationalization of work in pharmacies, various devices are often installed and used, and it is required to downsize without sacrificing the functions of the devices so that the space at the installation site can be used effectively. ing.

(Prior Art) Particularly, in a medicine packing machine, after supplying a medicine and dividing it into a required number, one by one is sequentially packed by a packing mechanism provided at the lower part of the machine body and sent out of the machine. Since the continuous packaging bag wrapped by the packaging mechanism is sent out to the outside with a natural gradient, the outer shape of the machine body becomes excessively large, which is inconvenient.

Therefore, the continuous packaging is formed so that the packaged medicine sachets can be rapidly conveyed obliquely upward from the position where they are delivered by the packaging mechanism, and then delivered to the next inspection table. A bag removing device is known, for example, from Japanese Utility Model Publication No. 61-30605.

(Problem to be Solved) In the continuous sachet-pulling-out device described above, in the packaging position, the packages oriented in the vertical direction receive the medicine one by one, and the rear opening is sealed and sent out. After changing its posture, it is suddenly lifted up, so after changing its direction, a continuous packaging bag is placed on a series of flat belts from a gently sloping surface to a steeply sloping surface. The continuous packaging bag is configured to be pressed and transferred as a whole.

However, when the conveyed continuous packaging bag is received on the inclined surface and is conveyed upward as described above, smooth feeding is difficult unless the packaging bag is always continuous. In other words, before inspecting a medicine packaging bag packaged based on a prescription, for example, when an operation of cutting and delivering the medicine packaging bag, such as two packages or three packages, is required, the package heat-seal unit In order to transfer to the feeding device after being cut at the position where the bag comes out of, the posture of the sachet is first changed and transferred to the conveyor belt, and the divided sachet is lifted while pressing the sachet. It is useless if the operation cannot be performed reliably. However, with a method such as a known take-out device, although it is useful for sending out continuous packaging bags, it is difficult to send out in a correct posture in the case of divided divided packaging bags. Also, when the amount of medicine to be packaged is large (for example, 4 grams, 5 grams, 6 grams), or when a tablet having a large particle size is packaged, etc., it is arranged on the steep conveyor belt and its front side. When it is lifted by being sandwiched between the holding plate and the holding plate, the holding plate does not move together, so frictional resistance is given to the surface of the moving sachet, so that the lower movement surface and the upper movement prevention surface are Therefore, an external force acts in the opposite direction on the sachet, which makes it difficult to smoothly deliver the sachet, and sometimes the bag is broken.

In the present invention, such a problem is solved, even if it is a continuous packaging bag or a divided packaging bag divided into required lengths,
Also, even if the packaging bag has a large packaging volume or is bulky, it can be taken out of the packaging position without any trouble and smoothly sent to the next work process. Has an aim.

(Means for Solving the Problem) According to the present invention, a direction changing guide of a sachet is provided adjacent to a feeding section of a packaging mechanism of a medicine packing machine, and a sachet is provided from directly below the direction changing guide to an upper side thereof. A bag carrier is installed,
The transfer device is divided into a horizontal transfer belt having a required width arranged immediately below the direction changing guide, and an inclined transfer belt which has a lower end adjacent to the transfer end of the transfer belt and which rises at a steep upward slope. The two conveyor belts are synchronously driven, and a soft pressing plate is movably arranged in the conveyor direction above the conveyor surface of the inclined conveyor belt so as to contact the conveyor surface side. A soft kneading roller is arranged above the end of conveyance.

In the present invention, a pressing spring for the pressing plate is stretched between the conveying belt support frames on the upper side of the pressing plate provided to face the inclined conveying belt according to the condition of the sachet to be handled, and a biasing force is applied. It is preferable to be adjustable. Further, it is preferable that the pressing plate is made of a soft material and is bent so as to draw a convex curved surface toward the conveying surface, and it is desirable to attach a largely bent receiving guide plate piece to the lower end thereof.

Further, it is preferable that the tilted conveyor belt has a structure in which the tilt angle can be freely selected through its support frame.

(Operation) In the device of the present invention having such a configuration, when the continuous medicine packaging bags which are divided and packaged are delivered from the packaging mechanism, they are placed on the horizontal conveyor belt by the direction changing guides and are incorporated at the end of the conveyance. It is sandwiched between the roller and the horizontal conveyor belt and is positively fed onto the conveyor surface of the inclined conveyor belt.

In the inclined conveyor belt, a soft holding plate is arranged in a curved shape from the upper side on the conveying surface side, and the medicine packing bag is positively put between the guide plate attached to the lower end and the conveying surface by the take-in roller. And the medicine-packaging bag to be conveyed is conveyed by the inclined conveyance belt by the pressing spring force.

Then, even when the packaged medicine packaging bags are cut into the required number and sent out, after being placed on the horizontally traveling conveyor belt by the direction changing guide, the kneading rollers positively incline the conveyor belt. When the cut medicine packaging bag is fed between the holding plate and the holding plate, the holding plate bends and is conveyed from the receiving part at the intermediate position by pressing the medicine packaging bag to be conveyed on the conveying surface with the holding spring. As a result, even a short medicine packaging bag that has been cut can be transported without displacement. Even if the medicine packaging bag has a large amount of medicine packaging and is bulky, since the pressing plate is curved and movably arranged in the vertical direction, the pressing plate is lifted by the thickness. Therefore, the pressing plate moves appropriately along the conveyor belt, and even if the frictional resistance increases, the pressing pressure plate moves appropriately and the frictional resistance can be reduced when the pressing spring force is applied. Because it can be done, it can be transported without difficulty.

(Effects of the Invention) According to the present invention, not only continuous sachets but also short sachets cut after packaging such as two-pack cut or six-pack cut cause the transport posture to shift. It is possible to reliably transfer from a low position to the workbench of the next process without any problem, and it can be configured to be transferred in the main frame of the packing machine, and the medicine packing machine can be packaged without increasing the size of the medicine packing machine. I was able to do it.

(Example) The carrying-out apparatus of the sachet in the medicine packing machine of the present invention will be described below with reference to the drawings.

FIG. 1 to FIG. 5 show one embodiment of the present invention, which is a heat seal device of the packaging mechanism 10 in the medicine packing machine.
A pair of sachet direction changing guides 13 and 13 'are attached to the outlet side of a support 12 of a cutter disposed adjacent to the cutter 11. This direction change guide 13, 13 'is the second
As shown in FIG. 4, FIG. 5 and FIG.
A pair of direction changing guides 1 so that the sachet Pouch A, which is sent out from 11 and then fed out via a cutter (not shown), moves while twisting from a vertical orientation to a horizontal orientation.
The mounting direction of 3,13 'is set.

A horizontal conveyor belt 20 is arranged in a required section immediately below the direction changing guides 13 and 13 ', and an inclined conveyor belt 30 having a lower end positioned adjacent to the end of the horizontal conveyor belt 20 is provided. Is placed upright with an inclination of about 60 to 40 ° with respect to the conveying surface 21 of the horizontal conveying belt 20, and the sachets A fed from the packaging mechanism 10 by the both conveying belts 20 and 30 are The conveyor is configured to be sent out to the workbench of the process.

As the horizontal conveyor belt 20 and the inclined conveyor belt 30, flat belts having a proper width are used, and support frames 25 and 35 are provided so as to travel in synchronism with the power from a single drive unit 18.
Is wound around the pulleys 22 and 23 and the pulleys 32 and 33 arranged in the. In addition, the support frame of the inclined conveyor belt 30
The 35 is a fuselage 15 so that the inclination angle can be set arbitrarily as needed.
The support metal fitting 16 attached to the side may be movable so that the inclination angle can be arbitrarily set.

At the upper position of the end pulley 23 of the horizontal conveyor belt 20,
For example, a soft kneading roller 26 whose outer peripheral portion is formed of a sponge layer is movable in a vertical direction so that it can be rotated.
It is supported and arranged at 27.

A holding plate 36 is formed on the upper side of the conveying surface 31 of the inclined conveying belt 30 by a soft material plate having a width substantially the same as the width of the conveying belt 30 such as a soft urethane resin plate, and is conveyed as illustrated. A curved surface with a convex surface facing surface 31,
It is supported by the engagement of the receiving plate 35 ″ and the latch 37 so that the upper end does not come off, and both edge plates of the supporting frame 35 in the middle position of the lower half.
A pressing spring 38 is stretched between 35 'so that the mounting position can be changed according to the packaging amount of the package bag A to be processed, and the curved portion of the pressing plate 36 is brought close to the conveying surface 31. There is. A guide piece 39 bent upward is attached to the lower end of the holding plate 36.

In the device of the present invention thus configured, the medicine is sequentially put into the packaging bag by the packaging mechanism 10 and sealed by the heat sealing device 11, and when the medicine is cut into the required number of packages and sent out, the direction of attaching to the support 12 is obtained. When the sachet bag A passes through the conversion guides 13 and 13 ', the direction is gradually changed from the vertical position to the horizontal position, and the bag is placed on the horizontal conveyor belt 20 and transferred. The sachet A reaching the end of the horizontal conveyor belt 20 has a conveying surface 21.
It is nipped by the take-up roller 26 and fed to the side of the inclined conveyor belt 30. The conveyed sachets A fed onto the inclined conveyor belt 30 are pressed by the pressing plate 36 against the inclined conveying surface 31, so that the inclined conveyor belt 30 is pressed.
Carried by 30. At this time, since the pressing plate 36 is formed in a convex curved surface toward the transport surface 31 and is always in a state of pressing the pressing plate 36 with the force of the pressing spring 38, the pressing plate 36 is provided with the guide piece 39 at the lower end and opened. The leading end portion of the conveyed packaging bag A, which is nipped and transported by the take-in roller 26 and the horizontal transport belt 20, is reliably fed into the existing portion, and if it shifts to the inclined transport belt 30 side, it bends and the pressing spring 38 force is applied. As a result, the package bag A to be transported is positively pressed against the transport surface 31 and carried up.

When the holding plate 36 passes through the most narrow part due to the bending, the following sachet bag A is slanted to the inclined conveyor belt 30 (conveying surface) in the same manner as described above.
Since it is carried in close contact with 31), even if the carrying surface 31 has a steep slope, the carried sachet A can be carried up without slipping. Further, even if the thickness of the sachet B to be transported A during transportation fluctuates due to the size of the contents, the holding plate 36 fluctuates vertically to follow the transportation surface 31 and is movable in the moving direction. Therefore, the sachet does not become overloaded, and the bag can be smoothly transported without breaking. Therefore, even if it is cut into a short length such as two packets or three packets, it can be transported without trouble. Of course, there is no problem in the case of continuous sachets.
