Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention provides a method for handling packaged medicines in a medicine packaging machine.
This invention relates to a dispensing device for sachets that can be rationally sent out of the machine from a packaging position in a narrow space.

(Background of the Invention) If a drug packaging machine used to package prescribed drugs (pharmacies in hospitals, clinics, etc.) has a large capacity, the device will naturally be large and the installation space will be proportionally large. It gets bigger. However, with the rationalization of work within pharmacies, various types of equipment are increasingly being installed and used, and in order to make effective use of the installation space, there is a need to downsize the equipment without compromising its functionality. ing.

(Prior art) Particularly in a drug packaging machine, after a drug is supplied and divided into the required number of pieces, each package is sequentially wrapped in a packaging mechanism provided at the bottom of the machine and sent out of the machine. Because of this, successive packaging bags wrapped by the packaging mechanism are sent out to the outside at a natural slope, which is inconvenient because the exterior size of the machine becomes excessively large.

Therefore, we created a continuous package in which the divided drug sachets are suddenly conveyed diagonally upward from the position where they are fed out from the packaging mechanism, and are quickly sent to the next inspection table. A bag removal device is known from, for example, Japanese Utility Model Application Publication No. 61-30605.

(Problem to be Solved) In the device for taking out continuous sachets mentioned above, the packaging, which is oriented vertically at the packaging position, accepts drugs one by one and is delivered with the rear opening sealed, while the packaging is oriented horizontally. After changing its posture, the bag is suddenly carried upwards, so the bag is conveyed from above by a presser plate from above by placing the continuous packaging bags on a series of flat belts from a gently sloped surface to a steeply sloped surface. It is configured to transfer the continuous packaging bag by pressing it generally.

However, when continuously conveyed packaging bags are received on an inclined surface and conveyed upward in this way, smooth delivery is difficult unless the packaging bags are always continuous.

In other words, if an operation is required to cut and send out two or three color bags before inspecting drug sachets that have been packaged based on a prescription, the heat seal section In order to transfer the cut bag to the feeding device after it has been cut at the position where it exits, a two-step process is required: first change the posture of the divided bag and transfer it onto the conveyor belt, and then lift the divided bag while holding it down. It is useless if it cannot be operated reliably.

However, although methods such as known take-out devices are useful for delivering continuous packaging bags, it is difficult to deliver divided sachets in the correct posture.

In addition, when the amount of medicine to be packaged is large (for example, 4 grams, 5 grams, 6 grams), or when tablets with a large particle size are packaged, it is necessary to Since the presser plate does not move together with the presser plate, a large frictional resistance is applied to the surface of the moving sachet, which causes the lower moving surface and the upper movement blocking surface to This causes an external force to act on the sachets in the opposite direction, making it difficult to send them out smoothly and sometimes causing the bags to break.

In the present invention, such problems are solved, and whether it is a continuous packaging bag or a sachet bag divided into required lengths,
In addition, we have created a conveyor system for compactly packed sachets that can be taken out from the packaging position and smoothly sent to the next work process, even if the sachets are large or bulky. The purpose is

(Means for Solving the Problems) The present invention provides a direction change guide for sachets adjacent to a feeding section of a packaging mechanism of a drug packaging machine, and a direction change guide for packaging sachets from directly below the direction change guide to an upper side of the bag. A bag conveying device is installed,
The conveyance device is divided into a horizontal conveyance belt of a required width disposed directly below the direction conversion guide, and an inclined conveyance belt that rises at a steep slope upward with its lower end adjacent to the conveyance end of the conveyance belt, Both conveyor belts are driven synchronously, and a soft presser plate is disposed above the conveyor surface of the inclined conveyor belt so as to be movable in the conveyance direction so as to be in contact with the conveyor surface side, and The structure is such that a soft feed-in roller is disposed above the end of the conveyance.

In the present invention, a biasing force is applied to the upper side of the presser plate provided facing the inclined conveyor belt by stretching a presser spring against the presser plate between the conveyor belt support frames according to the conditions of the sachets to be handled. Preferably, it is adjustable. Further, it is preferable that the presser plate be made of a soft material and curved so as to draw a convex curved surface toward the conveyance surface, and it is preferable that a receiving guide plate piece that is greatly curved is attached to the lower end of the presser plate.

Further, it is preferable that the inclined conveyor belt has a structure in which the inclination angle can be freely selected via its support frame.

(Function) In the device of the present invention having such a configuration, when a continuous divided drug packaging bag is fed out from the packaging mechanism, it is placed on a horizontal conveyance belt by a direction change guide, and at the end of the conveyance, it is rolled up. It is sandwiched between the rollers and the horizontal conveyance belt and is actively fed onto the conveyance surface of the inclined conveyance belt.

In the inclined conveyance belt section, a soft holding plate is arranged in a curved manner from above on the conveyance surface side, and the drug sachets are actively pushed between the guide plate attached to the lower end and the conveyance surface by a roller. The medicine sachets to be conveyed are conveyed by the inclined conveyance belt by the force of the pressing spring.

Therefore, even when the divided drug sachets are cut into the required number and sent out, they are placed on the horizontally running conveyor belt by the direction change guide, and then the retracting rollers actively transfer them to the inclined conveyor belt. When the drug sachets canted between the presser plate and the presser plate are fed, the presser plate bends and at an intermediate position from the receiving portion, the presser spring presses the drug sachets to be transported on the conveying surface and conveys them. Therefore, even if the medicine packaging bag is cut and short, it can be transported without causing positional shift.

In addition, even if the drug packaging bag is bulky due to the large amount of drug packages, the holding plate is curved and movable in the vertical direction, so the thickness of the holding plate does not lift up. As the belt moves along the conveyor belt, even if the frictional resistance becomes large, the presser plate appropriately moves to follow the section where it is in a pinched state, and reduces the frictional resistance after passing the position where the pressing spring force is applied. This allows for easy transportation.

(Effects of the Invention) According to the present invention, not only continuous sachets but also short sachets cut after packaging, such as two-color cut or six-pack cut, can be prevented from shifting in their conveying posture. It is possible to reliably transport drugs from a low position to the workbench for the next process without any problems, and it can be configured to be able to be transported within the main frame of the drug packaging machine, allowing drug packaging to be carried out without increasing the size of the drug packaging machine. Now you can.
