Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ampoule dispensing device. More specifically, the present invention includes a grooved flat bar that horizontally moves ampules placed upright, and a bridge that divides the ampules into two by two and swings them left and right at the stepped portion of the flat bar. A bridging removal plate is used to remove the bridging, and the ampoule with the bridging removed is held in an upright state and moved vertically upward from the grooved flat bar, and at its upper end position, the ampoule retention is released and transferred via the delivery roll. The ampoule feeding device is loaded onto an ampoule supply device comprising an ampoule lifting means for delivering the ampoule in a sideways state to a chain conveyor.

Ampules filled with chemical solutions are transported by an ampoule supply device from one process to the next in order to undergo operations such as printing and packaging before becoming products. The device K that has been generally used as this ampoule supply device is (
a) Starwheel type, (b) set of screws, and (
c) Swing type (this is further classified into horizontal type and tilt type).

However, each of these ampoule feeding devices takes out ampoules one by one from an ampoule hopper or an ampoule transfer belt conveyor while eliminating the bridge formed at the ampoule barrier. Due to the large frictional resistance that acts between the ampoules, the wILI! of the ampoules! I is likely to occur.

(2) A large amount of noise is generated due to contact between ampules at the ampoule removal section. (3) Ampoule supply capacity i
j 260 to 300 lines/min is the limit, and higher speed Klfi cannot be supported. (4) It takes time to remove and clean damaged ampoules. There was a vagueness between the two.

The present invention has been developed in consideration of these circumstances, and one of its main structural features is the use of ampoule lifting means that moves vertically upward from a grooved flat bar to take out the ampoule. be. This is a friend that can reduce the frictional resistance at the ampoule extraction part.
In addition to making it difficult for the ampoule to break, it is possible to suppress the generation of noise. In addition, it is possible to take out multiple ampoules at once instead of one by one, so by increasing the number of ampoule supply rows,
The riverboat will be able to handle higher speeds of 600 to 700 boats/min.

Another feature of the present invention is that in the stepped portion of the grooved flat bar, a bridge removal plate is provided which is divided into ampoule guide plates and swings slightly in the left and right direction.
This allows bridging to be removed simultaneously for a plurality of ampoules without causing damage to the ampoules or generation of noise. In the Zero Shot eJ4, if a plurality of ampoule guide plates are further arranged between the bridge removing plate and the ampoule lifting means, the ampoule from which the bridging has been removed can be transported as it is to the ampoule lifting means. This is preferable because it allows

The present invention will be described in detail below based on embodiments shown in the figures.

An ampoule discharge stand [35] for taking out broken or soiled ampoules is provided on the downwardly swiveled extension of the grooved flat bar (3).

Next, ampoule supply device (1) consisting of the above configuration
Explain how it works.

First, place the sterilized box (36) in which 1 ampoule 1 is lined up on the ampoule supply table (2), and use the shutter (3) of fR Sonoryo (36) to remove the ampule A1 from the scraper (3B) K. from the ampoule supply table (2) onto the grooved flat bar (3). While repeating this replenishment, the bridge removal plate (4) is moved from the swinging member (13) K.
) is reciprocated 2 to 3 times in the left and right direction at a rate of approximately 160 times/mn, as shown in Figure 3, the ampoule between the bridge removal plate (4) and the ampoule guide plates (5a) and (5b) is removed. The bridge B#i in various states that had been formed in mutual reference has been dissolved, and the ampoule guide plate (5a),
(5b) Ampoule lifting plate (
The ampules on the grooved flat A-C3) have reached the entire row ampoule lifting plate (1'/). When this is confirmed by the sensor (33) built into the moving plate [1], the grooved flat bar [

b) Both upper and lower ends are held as shown in K, but when the cam floor (24) moves from the concave part (21) of the plate cam (19) to the upper convex part (20) K, the ampoule branch tip holding member (30) Since it is opened by the rotation of the #1 arm (25), the ampoule 3, which is only supported by about % of its diameter on the L-shaped claw (23), falls toward the ampoule delivery roll ( ) due to its own weight. (See Figure 6(c))
. When the ampoule lifting plate (17) moves further upward, the ampoule s#i ampoule partition plates (22) (22) restrict the inclination in the left and right direction, and the rotating action of the delivery roll (7) allows the ampoule to fall smoothly. condition
Ampoule transfer chain conveyor that can change direction (8)
(See Figure 6(d), (@)). The ampoule 4 on the chain conveyor (8) is conveyed to the next process when the ampoule lifting plate (gilt) starts to descend.

When the ampoule lifting plate (17) descends and returns to the home position, the one-turn clutch for driving the ampoule lifting board (not shown) is disengaged and stopped at the home position, and at the same time, the grooved flat bar (3) is moved again. The ampoule is then transported towards the ampoule lifting plate (1 piece). Thereafter, the same operation is automatically repeated, and the apples in the upright state are automatically supplied in the ampoule transfer chain conveyor (8)K in the lying state.

As is clear from the above description, this device can provide the following excellent effects.

(&) Ampules supplied upright on a grooved flat bar can be taken out by moving all rows vertically at the same time, although it may be difficult to do so, increasing the number of ampoule supply rows. Compared to the conventional case where ampoules were taken out one by one, the ampoule supply capacity has been increased by 600 ml.
It is possible to improve the KNE to about 700 lines/Iin and increase the speed.

(b) Eliminating the various bridges that occur between the ampoules on the grooved 7-rat bar is done by moving the bridge removal plate slightly back and forth in the left and right direction by about 2 to 31 cm, so the force acting between the ampoules is small and impossible. No force acts on it. Therefore, not only the noise generated due to mutual contact between the ampoules is reduced, but also the occurrence of breakage of the ampule can be suppressed.

(e) Since the ampules are removed in a direction perpendicular to the horizontal transport direction, the friction between the ampoules is small and almost no force acts between the ampoules, which may cause noise or breakage when removing the ampoules. rarely occurs.

(d) Even if an ampoule breaks on the grooved flat bar, the liquid content will flow into the ladder-shaped groove of the grooved flat bar, reducing the number of other ampoules contaminated with the liquid content of the damaged ampoule. Since there are fewer items, the time required for cleaning up is reduced. Also, ampoule rising moving board! ! By stopping directly above, moving the grooved flat par, and placing the imitation ampoule on the ampoule ejection stand at the rear, you can easily clean up the damaged ampoule.
