Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to medical containers such as mulberry bottles and syringes, and rubber stoppers and caps used in bottles for trust items.
This relates to a device for subjecting a fist to a series of processes of washing and drying it, and then discharging the fist through a rubber stopper next to the fist.

Conventionally, with this cypress rubber stoppering device, the gauge pressure inside the pressure tank for sterilization treatment was 1. ! The net-like casing containing the rubber stopper is washed under atmospheric pressure while rotating in washing water, sterilized by supplying acid-free steam, and then left to dry naturally.The rubber stopper is then manually removed from the tank. The bottles were taken out and fed into the feeder of an automatic machine that attaches rubber stoppers to bottles MK in the next step. In this conventional device, the rubber stoppers were manually removed from the tank after processing using a batch method, which caused problems in terms of work handling, and many of the rubber stoppers were containers with sizes ranging from 11 to 250 mm, and were made of small pieces of silicone. Most of them are made of rubber, so if they get tangled, not only will a bridging phenomenon occur during dispensing from the dispensing port, which will hinder dispensing, but rubber stoppers originally have a cut or hollow hole for insertion. Shape of formation - There are many 〇 items, which increases the tendency for them to get caught or tangled, making it difficult to drain out of the tank.Also, it becomes impossible to discharge a constant amount, which is necessary for supplying to the 4th process. Recently, there was a problem with handling operations.

The present invention aims to accurately eliminate these conventional drawbacks, and requires no manual labor to remove the rubber plugs. The objective is to provide a quantitative discharging device in a rubber stopper container [8], which can be processed while being sealed and connected, is easy to handle, and can perform processing operations safely, with a simple configuration and at a low cost. .

In addition, the present invention provides an apparatus that can eliminate the bridging phenomenon of rubber plugs through a deplating process, efficiently discharge the rubber plugs, and can intermittently derive the amount of rubber plugs discharged from the outlet. .

The present invention provides an apparatus in which a rubber stopper outlet provided in a pressure tank for accommodating rubber stoppers for cleaning, sterilization, and drying processing is provided with a discharge tank *t' that can open and close the outlet. , the outlet is opened at the bottom 11 of the pressure tank a
A cone valve that approaches and separates from the SS outlet is provided so as to be movable up and down and communicated with the outlet, and the relationship between the pressure tank and the cone valve circumferential wall is made variable.

This pressure tank 1 is partitioned into a funnel-shaped chamber 11 by a permeable partition wall 1G made of a perforated plate such as punched metal inside the tank.
At least the inlet 3 and the outlet 3 of the rubber stopper are opened to the pressure tank 1 in direct communication with the sterilization chamber 11. Furthermore, pressure tank 1
The tank is equipped with a vacuum nozzle II to create a reduced pressure inside the tank.

The Tsumugi quantitative discharge horizontal horizontal 8 consists of a cylinder II and a rotary body i1 horizontal 1116 installed on the upper part of a pump 14 which is placed vertically in the center of the tank and protrudes outside the tank, and 9 tons of cone valves are installed on the base. , is configured to be able to move up and down as well as rotate freely.

The cone valve has a tapered outer periphery that fits and seals the funnel-shaped discharge passage 7, and the vertical movement of the cylinder 11 opens and closes the pressure volume or pushes out and discharges the rubber stopper. In this case, the amount of rubber stopper to be discharged is determined by the stroke of the cylinder li. Further, this cone valve 9 is equipped with one wire-like stirring blade for eliminating bridging, and stirring is performed by rotating the support shaft 14 by the rotation transmitter 11116. Furthermore, as for the shape of the cone valve 9 @ and the discharge passage 1 at the lower end of the tct vehicle 4, as shown in detail in FIG.

The water-permeable partition *1G is designed to allow solid-liquid separation and drainage to be carried out well and accurately, but any heat-resistant and water-permeable member such as a wire mesh may be used. The outlet 3 is configured as a pit at the bottom of the container by providing a gap between the containers to form a drainage channel with the water permeable partition #&10, and is provided with a cone-shaped opening/closing valve 9 for opening and closing the f% cough outlet s'lt. There is.

The stirring g17 installed in this opening/closing valve is a ring-shaped wire member that protrudes radially, but it also has a plurality of plate-shaped twisted blades or bar-shaped protrusions that protrude to achieve the stirring function and bridge elimination function. We are considering having it in the future.

In the figure, 18 is a diffuser pipe with a supply air low, 19 is a supply 1
The liquid supply pipes connected to the lII port 4 are respectively opened in the tangential direction of the inner circumference of the reduction chamber 11 to generate a swirl aV. sO is a cold water channel, 31 is a non-steam supply port, SS is a bearing, am is an overflow pipe, 34-9 = is a cylinder support, ms, m@ is a 1L1 valve, blade 7 is a handle for automatic opening/closing operation, IS is a It is a supporting leg.

In the example in Figure 3, the discharge path connected to the outlet IK of the pressure tank 1 is a chute 2G that is made to flow down the path by gravity using a rubber stopper, or if it cannot be removed as in the example in Figure 4, a feeder 30L is used. [It is better to automatically transport the treated rubber stopper to the next step of sealing without touching it manually.

After that, hot water is injected from the liquid supply pipe 19, and non-II!I steam is blown from the 121"C gauge pressure of 1.latm to sterilize the water and drain the water. When heated, it is difficult for the rubber plugs to weld together, and if an appropriate means is used to create an agitation flow, the rubber plugs are less likely to wear out.

Thereafter, the pressure is removed and cold water is allowed to flow through the cold water channel 30 to cool the pressure tank 1'%, and the vacuum nozzle 13 is used to vacuum the tank to -10-1750 mm for drying. In this case, drying can be done in a short time by introducing a small amount of air at a temperature below -50°C.

After the drying is completed, the valve 9Y and the cylinder 1G are moved up and down with a constant stroke to send out the rubber stopper in fixed quantities to the next process in a sealed manner. Even if the rubber plugs form a bridge shape during dispensing, this is effectively eliminated by the stirring blades 1) and the rotational elevating motion of the cone drop valve, resulting in smooth quantitative dispensing.

The present invention provides a discharge mechanism that can open and close the outlet for rubber stoppers provided in a pressure tank that accommodates rubber stoppers and processes them for cleaning, sterilization, and drying! In the device equipped with the above-mentioned outlet Y, a cone valve tJJ is provided with an opening at the bottom of the pressure tank and connects and separates from the outlet; 1 by making the rubber plug storage volume containing PAL' variable and forcing the rubber plug inserted and supported into the storage volume to fall under pressure at the bottom of the cone valve.
