Description

Field of the invention

The present invention relates to a two-row plant for the production of medical plastic bag, in particular in which, when manufacturing the medical plastic bag for storing a medicament for medical treatment by sealing a two-layered synthetic resin film S by means of a compressing heating plate, the cavities c for shaping on this compressing heating plate the medical plastic bag are arranged in a double-row structure and also a conveyor track for conveying the medical plastic bag on both sides, ie each on a right and on the left side of the double-row system, so that the productivity of the medical plastic bag can be significantly improved.

State of the art

Any type of liquor to be applied to the human body, such as e.g. Infusion solution, peritoneal dialysis solution, blood, etc., stored in a constant-life medical container, such non-PVC pouch-shaped container used for storage being referred to as a medical plastic bag. If this medical plastic bag filled with a drug, then it is referred to here for convenience as a medical solution bag.

A manufacturing process of the medical plastic bag is performed such that a resin film is sealed to the particular shape and then cut along a sealed edge, so that a chamber capable of accommodating the drug is formed, thereby producing a pouch-shaped medical plastic bag. In this case, a tube is installed in an edge seal of the medical plastic bag, through which a medical solution can be injected into the chamber. Therefore, if a port is inserted into the tube through the tube after injecting the drug into the bag, the medical solution bag is made.

The port is used to pierce a puncture spike to duplicate an amount of drug stored in the medical solution bag, or to pierce a syringe so that another drug is mixed with the stored drug, usually from a port body having its lower end in the syringe Pipe is inserted, and consists of a rubber stopper and an end cap, which are attached to the upper part of the connector body.

From the prior art, in particular from the patents KR 10-1081820 (published on November 3, 2011), KR 10-1056869 (published on 8. 8. 2011) and KR 10-1014286 (published 7. 2. 2011), etc., the equipment for the production of the above medical plastic bag are proposed. In this context, the plant for the preparation of the medical solution bag according to the patent KR 10-1081820 summarized, then it is designed such that a film feeder 100, a film conveyor 200, a connector inserter 300, a bag manufacturer 400, a baggage conveyor 500, a bag holder means 600, a medicine solution filling device 700, a terminal cover device 800th and medical solution bag outlet means 900 are arranged continuously in the order indicated.

In the above medical solution bag manufacturing system, a compressing heating plate 410 and a cutting plate 420 of the bag manufacturing device 400 are arranged in a row, the number of compressing heating plates 410 and cutting plates 420 dividing a working process being only two to three Therefore, with this single row structure, the productivity improvement of the medical plastic bag has reached its limits.

In this case, even if the productivity of the medical plastic bag were increased by the increase in the number of the compressing heating plates 410 and cutting plates 420, the length of a two-ply film, which is processed only by a division of the working process, would be lengthened too long, making the film difficult Therefore, it is feared that the unevenness in quality arises between the medical plastic bag formed upstream in the compressing heating plate 410 and the medical plastic bag formed downstream in the compressing heating plate 410 and, moreover, the number of drive means 430 for driving As a result, the production of heating plates is increased, which makes production relatively inefficient.

Particularly, when manufacturing a small medical plastic bag having a relatively small size by the conventional single-line manufacturing equipment, there has been a problem that the productivity is very low and also the use efficiency of the synthetic resin film as a raw material is too low, leading to an increase in cost ,

First, the film feeder serves 10 for the continuous supply of a two-ply synthetic resin film S with a certain width and consists of a spool shaft 11, on which a coil, on which the film S is wound up, attached; a roll up and down 12 always to maintain a proper tensile force of the unwrapped from the coil film S moved up and down; and a foil tie bar 13 that when replacing the coil, the cut ends of the two films S connects with each other.

Second, the printing device serves 20 for repeatedly printing the letters or figures on a surface of the film S in that the structure of the printing device can be any structure of all printing devices used to make a conventional medical plastic bag. According to an embodiment of the present invention, the printing device is composed 20 , like out 1 and 2 seen from a stamp plate 21 , on whose underside certain letters or figures are embossed, and a printed film 22 , Press the stamp plate 21 therefore, the print film 22, then those at the bottom of the stamp plate 21 Embossed letters or figures on one side of the film S printed.

Furthermore, the film conveyor is used 30 for repeatedly feeding the film forward S at a certain distance and consists of a foil suction bar 31 and a foil support rod 32. In doing so, the foil suction rod moves 31 above the slide S back and forth back and forth and so fulfills a task for sucking the film S and so to repeatedly forward the film S at a certain distance. This moves the foil suction bar 31 while sucking in an upper side of the film S by a certain distance forward, while moving backward the slide S from the film suction bar 31 separated and so only this is moved backwards.

This will make the slide S to a way of the film suction bar 31 repeatedly conveyed, wherein along this conveying path, a division of a working process is performed. Ie if the film S stops, guides or guides the printing device 20 or the bag sealing device 40 and the bag cutter 50 via a route corresponding to the conveying a pressure work or a sealing and a cutting work through. Even when resting the film S the roll up and down decreases 12 further down and so does the pulling force of the film S one.

In addition, the bag sealing device serves 40 for forming a plurality of chambers, each divided into a specific size, for storing an infusion solution by thermosetting the two sides of the film S being from above on top of the film S arranged, compressed heating plate 41, a support plate 42 for supporting a bottom of the film S , and a drive for moving the compressing heating plate up and down 41 consists. Also below a bottom of the compressing hot plate 41 the cavities C are provided for sealing the chambers, usually a cavity C each a medical plastic bag B shaped.

One of the features of the present invention is that in the bag sealing device 40 one connection pipe in each of the two sides of the film S is inserted and that at the compressed heating plate 41 the cavities C for sealing the chambers in a double row structure are arranged side by side. This will do so in each of the two sides of the slide S inserted connecting pipe sealed in each case in the mutually separate chambers. It is advantageously provided that the number of cavities C , each in each one a compressing hot plate 41 are arranged four, six, eight or ten.

The enclosed 4 shows a structure below a bottom of a compressing heating plate 41 according to an embodiment of the present invention, wherein such a structure is shown that eight cavities C in a running direction of the film S arranged in two rows one after the other. Therefore, you can also use eight medical plastic bags B per division unit of the working process, with each medical plastic bag B a pair of connecting pipes is sealed.

In addition, the bag cutter is used 50 for making several, separate, plastic medical bags B by cutting a respective intermediate area between the chambers, forming an insert 51 that are above the top of the slide S moved up and down; a support plate 52, which is below the bottom of the film S the cutting plate 51 Abstüzt; and a drive, which is the cutting plate 51 can move vertically; having.

Below the bottom of the insert 51 is a cutting knife 41 before, the arrangement structure of the cavities C of the compressed heating plate 41 equivalent. Sinks the cutting plate 51 Therefore, from then cutting the cutting blade from the respective intermediate area between the chambers, so that several medical plastic bag B be separated from each other. Such are the size and number of medical plastic bags made this way B the size and number of underneath the bottom of the compressing hot plate 41 provided cavities C it is not necessary to cut the edge portions of each medical plastic bag separately.

In addition, the conveyor belt provides 60a respectively. 60b one of the features of the present invention, each along a respective particular orbit on left and right sides of the bag sealing means 40 and the bag cutter 50 is provided and each of a tube support pin 61a respectively. 61b , a tube insertion means 62a and 62b and a bag retractor 63a respectively. 63b is how it looks 3 seen.

The tube support pins rotate 61a and 61b along the orbit containing the left and right sides of the bag sealing device 40 and the bag cutter 50 happens in an opposite direction. Ie in 3 The left (upper) tube support pin rotates 61b clockwise, while the right (lower) tube support pin 61a rotates counterclockwise, the two tube support pins then from the two sides of the film S between two layers of the film S When they are the bag-sealing device 40 to reach. Here are the pipe support pins 61a and 61b arranged so continuously, that the number of connections, in each one a medical plastic bag B be sealed, can become a bundle. In the enclosed 3 the case is shown that the pipe support pins 61a and 61b each are arranged as a pair of two continuously, with two terminals in each one a medical plastic bag B are sealed.

Furthermore fulfill the tube insertion devices 62a and 62b such a task, that in each case one of the tail pipes cut to a certain length before a position in which the pipe support pins 61a and 61b in each case the bag sealing device 40 reached, into the pipe support pins 61a and 61b can be inserted. In the bag sealing device 40 become the pipe support pins 61a and 61b and the connection pipe together from the two sides of the film between two layers of the film S used. In this state, the compressing heating plate sinks 41 down so that the chambers are formed for storage of an infusion solution.

It may be provided that in the bag-sealing device 40 an opener (not shown) is attached, thus the two sides of the film S spread apart that the tube support pins 61a and 61b and the connecting pipe between two layers of the film S easy to use. Furthermore, it may also be provided that in the pipe insertion devices 62a and 62b each a pipe separator (not shown) is mounted, which can cut a continuously supplied pipe line to a certain length.

Alternatively, it may be provided that by means of the pipe insertion devices 62a and 62b just a connection body (not shown) instead of the connecting pipe in each case in the pipe support pins 61a and 61b is used. Then, the connector body in each chamber is just sealed, then an infusion solution is injected via the connector body into an inside of the chamber, and finally, a rubber stopper and an end cap are attached to the upper part of the connector body, thus making a medical solution bag.

Eventually, the bag take-back facilities will perform 63a and 63b such a task that the connection pipes in a position in which the support pins 61a and 61b the bag cutter 50 pass out of the support pins 61a and 61b are removed and so the medical plastic bag B can be withdrawn. The respective medical plastic bags are turning B by means of the bag cutter 50 are separated from each other, in a state in which the respective connection pipes in the pipe support pins 61a and 61b are inserted along these pipe support pins 61a and 61b until they each by means of the bag take-back devices 63a and 63b be withdrawn. Therefore, at the conveyor tracks 60a and 60b one guide rail each 64a respectively. 64b attached the medical plastic bag B supported so that they themselves are not sunk down. There are such guide rails 64a and 64b between the bag cutter 50 and the bag take-back devices 63a and 63b appropriate. In the enclosed 3 but it is for the sake of simplicity on the representation of the right guide rail 64a omitted, however, the structure of the right guide rail 64a essentially the left guide rail 64b is equal to.

In contrast, it can be inventively provided that between the bag-sealing device 40 and the bag cutter 50 a second 71 and a third sealing device 72 for additional welding of a region between the chambers are mounted. In this case, the structures of the second 71 and the third sealing device 72 from the bag sealer 40 not substantially different, the second and third sealing means serving the outer portions of the respective ones in the bag sealing means 40 sealed chambers, in particular the peripheries of the respective connecting pipes to cure again under heat and thus to prevent the leakage of stored within the chambers infusion solutions.

In addition, it may alternatively be provided that the temperatures and pressures within the bag sealing device and within the second 71 and the third sealing device 72 are equal to or different from each other, the differences in temperatures and pressures being substantially different from the material of the synthetic resin film S and from the structure of the medical plastic bag B are dependent.
