Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a packaging device, more specifically, a packaging device for completely packaging three-dimensional items such as medical devices, especially syringes, and its purpose is to completely package three-dimensional items such as syringes. It is an object of the present invention to provide a packaging device which is very compact and has a simple structure as a whole and can enable simple and continuous packaging.

Conventionally, medical instruments, particularly syringes, have been packaged manually due to their complicated shapes, but the packaging process is complicated and has extremely poor workability.

The present invention has developed a packaging device with a completely new structure in order to eliminate such conventional complicated operations.The present invention is characterized by a sealer that heat-welds two packaging materials with their tops open. The packaging material formed after heat welding is held by a head attached to a chain extending outward from a driving shaft and a driven shaft so that it can be fed and guided.
and an auxiliary rotary transfer mechanism comprising a head attached to a chain that moves facing each other by sandwiching the head and packaging material in the parallel parts of the rotary feed mechanism, and the head of the rotary feed mechanism has a shaft as a fulcrum. The feeding pitch of the packaging material in the parallel portion of the rotary feeding mechanism is smaller than the feeding pitch of the packaging material during rotation, so that the packaging material is slackened in the parallel portion of the rotary feeding mechanism. It is in.

The specific configuration thereof will be explained below according to an embodiment shown in the drawings.

A is a packaging material made of a transparent film, B is a packaging material made of an opaque film, 1 is a guide roller, and 2 is the packaging material A
, B are provided in the passageways of the sealers, and the front side thereof is formed into an L-shape as shown in FIG.

3 is a guide roller, 4 is a chain 9 that is passed between each sprocket wheel 7, 8 of the driving shaft 5 and the driven shaft 6.
The rotary feeder holder 10 is a rectangular head attached to the chain 9 so as to protrude outward as shown in FIG. It consists of a saw blade-like cutter 11 for forming and several needles 12 protruding above and below the cutter 11 for forming perforations.

Reference numeral 13 denotes a pressing rod having a concave planar shape into which the head 10 is fitted, and is capable of reciprocating in a cylinder 14.

Reference numeral 15 denotes a sprocket wheel 20.21 having heads 16 arranged to face the head 10 at equal intervals in a parallel portion thereof, and a chain 17 to which the heads 16 are attached, provided on the driving shaft 18 and the driven shaft 19, respectively. 22 is a pair of sealers for thermally welding the upper surfaces of packaging materials A and B, and 23 is a discharge roller.

The operation of the present invention when packaging the syringe C having the above-mentioned structure will be explained.

First, when the packaging device is driven, the packaging materials A and B are pulled out and passed through the sealer 2 without being guided by guide rollers 1 and 3.

When this sealer 2 passes, the packaging materials A and B are soil and the lower edge ayb
Then, the continuous bag D is formed by heat welding with the sealer 2 in the state where the top surface is open, that is, the state shown in FIG.

Next, the thermally welded packaging materials A and B are further guided by a guide roller 3 and fed while being hooked and held by a head 100 needle 12 located on the drive shaft 5 side of a rotary feed mechanism 4.

At this time, the pitch of the head 10 is such that the relationship between the pitch circle of the sprocket wheel 7 and the circle of the trajectory of the head 10 is approximately 2:3.
In other words, since r:R=2:3, the data is sent in a long pinch.

Furthermore, when the head 10 rotates by a certain angle, the cylinder 14 is driven in synchronization with this, and the pressing rod 13 moves to protrude toward the packaging material and engages the head 10. Therefore, when pressing, the cylinder 14 is driven. The provided upper and lower needles 12 and the central cutter 11 make perforations 24 on the upper and lower sides of the facing surfaces of the packaging materials A and H, and cut in the middle to form a cut 25.

The packaging materials A and B in which the perforations 24 and cuts 25 have been formed in this manner are further fed to the syringe insertion portion 26 side (straight portion) by the feeding mechanism 4 while being bitten by the needle 12.

At this time, that is, when the head 10 rotates 180 degrees outward around the driving shaft 5, it faces the head 16 of the auxiliary rotary feeding mechanism 15 by the driving shaft 5 of the feeding mechanism 4 and the driving shaft 18 which is intermittently driven. and the pitch of the head 10.
J returns to the original pitch t and passes through the parallel portion with the heads 10 and 16 facing each other.

When the heads 10 and f6 face each other, the packaging material is held even more strongly by the head 10.

When the feed pitch of the head 10 is changed from the long pitch L to the original pitch t, the packaging material (bag) is in a slack state as shown in Fig. 5 because the packaging material is changed while being held in the head 10. The upper surface is open, forming a substantially circular shape.

When this opening is made, separately prepared syringes C are sequentially inserted from the top.

In this way, the syringe C... is inserted into the opening 2 of the packaging materials A and B.
7 and is fed by the feeding mechanisms 4 and 15 to the driven shaft 6.
, 19, both heads 10.16 are separated and at the same time the packaging material held by the head 10 is also detached from the head 10 and sent in a straight line between the next sealers 22.

The packaging materials A and H that were open when passing through the sealer 22
The top surface of the syringe C is heat welded to completely seal the syringe C, and the bottom and top portions are held together by the next discharge port roller 23, and the syringe C is discharged.

The packaging form after discharge is as shown in FIG.

In the above embodiment, it is also possible to ensure that the mouth is in the open state as shown in FIG. 5A by, for example, blowing air from the top of the bag just before inserting the syringe.

Furthermore, the bag's deflection is not limited to the opening shown in Figure 5, but may be in the form shown in Figure 8.

Note that the type of packaging material is not limited in any way, and although a syringe is described in this embodiment, it is not limited thereto.

Other design changes are possible within the scope of the present invention.

As described above, the present invention enables complete packaging of syringes, etc. with an extremely simple structure, and enables semi-automatic packaging of this type of product, which was conventionally done manually, greatly improving work efficiency. improvement and productivity were significantly increased.

Therefore, it is possible to install this packaging device in a hospital, etc., collect used syringes in one place, package them one after another, and perform intensive sterilization after packaging.The practical effect of this packaging device is This has come to be particularly noticeable.

Other uses are extremely dog-like. Furthermore, when taking out a packaged product, perforations are made at the top and bottom, making it extremely easy to tear the product along these lines.

Furthermore, since the middle part of the bag is cut, there is no unreasonable tension between the bags even when a syringe is inserted, resulting in an extremely excellent shape.

In addition, the overall structure is simple, easy to manufacture, and compact, making it extremely useful.
