Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an apparatus for injecting a chemical into a glass bottle immediately after being manufactured by a glass bottle manufacturing apparatus, for example.

[Conventional technology]

In the production of glass bottles, in order to increase the strength of the glass bottle, the inner surface of the glass bottle immediately after being taken out from the glass bottle manufacturing apparatus is subjected to a predetermined coating treatment, but in order to perform this treatment, high temperature (for example, 600 A predetermined amount of a chemical agent such as powdery ammonium chloride is put into a glass bottle in a state of about (° C.) to sublimate it.

FIG. 5 shows a conventional device for charging the above-mentioned chemicals. In this figure, 50 is a glass bottle discharged from a glass bottle manufacturing apparatus (not shown), which is conveyed by a conveyor 51 from the back side to the front side of the drawing. It is designed to move linearly.

52 is a chemical tank for accommodating and dropping the chemical 53 such as ammonium chloride, which is provided almost directly above the movement path of the glass bottle 50, and below the glass bottle 50.
A medicine dropping port 54 of a predetermined size is formed so as to overlap a part of the movement locus of the opening center of the. Reference numeral 55 denotes a shutter plate, which has a single hole 56 formed therein, normally closes the medicine dropping port 54, and opens the medicine dropping port 54 only when the glass bottle 50 passes below the medicine dropping port 54. Then, it is driven linearly in the horizontal direction by the solenoid 57. Reference numeral 58 is a bottle detector composed of a photoelectric tube or the like that detects an approaching glass bottle 50 and outputs a predetermined drive command to the solenoid 57.

[Problems to be solved by the device]

However, in the chemical injection device having the above configuration, when the amount of glass bottles produced by the glass bottle manufacturing device increases and the amount of glass bottles 50 conveyed by the conveyor 51 increases, the solenoid 57 that drives the shutter plate 55 is increased. It becomes difficult for the above-mentioned operation to follow the feed pitch of the glass bottle 50, and it becomes difficult to throw a predetermined amount of the medicine 53 into the glass bottle 50. Then, under the high temperature as described above, the chemical agent 53 is easily solidified, and therefore, the chemical agent dropping port 54 is clogged, so that there is a drawback that a predetermined amount of the chemical agent 53 cannot be put into the glass bottle. is there. Further, in order to prevent clogging of the medicine drop port 54 by the medicine 53,
Although it is conceivable to cool the medicine tank 52 with water, there is a drawback in that this method is not so effective, and in this case, the entire apparatus becomes large in size.

The present invention has been made in consideration of the above matters, and an object thereof is to provide a compact drug dispensing device capable of always smoothly dispensing a predetermined amount of a drug into a container. It is in.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, a drug injection device according to the present invention has a squeeze port at a position corresponding to the drug drop port below a drug tank that accommodates a drug and has a drug drop port at a lower portion thereof. Of a heat-resistant member having heat resistance and cushioning property, and a plate-shaped member which is rotated in contact with the lower surface of the heat-resistant member and has a plurality of holes arranged at equal intervals, and which is always stationary. The diaphragm part is closed by the shield part of the plate-like member, and the plate-like member is opened by rotating the plate-like member by a predetermined angle based on the detection of the container that moves linearly. The medicine is put into a container that moves linearly.

[Action]

The drug drop port of the drug tank and the squeezing port of the heat-resistant member are formed so as to correspond to each other,
Since the plate-shaped member is stationary so that the shielding surface closes the aperture, the drug in the drug tank does not drop.

Then, based on the detection of the container such as a glass bottle that moves linearly by the detector, the stationary plate member is rotated by a predetermined angle to open the aperture,
As a result, the medicine in the medicine tank is put into the container by a predetermined amount.

As described above, when the medicine is put into the container, the squeezing port is opened by rotating the plate member by a predetermined angle, and therefore, it is possible to cope with this even if the container feeding pitch is narrowed. it can. Further, since a heat-resistant member having heat insulating properties is provided below the drug tank, heat radiated from the container is hard to be transferred to the drug tank side, and the drug is solidified at the drug drop port or the squeezing port. Therefore, a predetermined amount of medicine can be constantly and smoothly introduced into the container.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

1 to 4 show an embodiment of the present invention. First, in FIG. 3, reference numeral 1 is a glass bottle as an example of a container into which a medicine is put, and a glass bottle manufacturing apparatus not shown. Manufactured by. Reference numeral 2 denotes a conveyor as a device for conveying the glass bottle 1, which is configured so that the glass bottle 1 can be moved substantially linearly and horizontally at least in the vicinity of a medicine feeding device 5 described later. Reference numeral 3 is a column, and 4 is an arm provided between the column 3 and the conveyor 2 side.

Reference numeral 5 is a medicine injection device provided so as to face the movement path of the glass bottle 1, and 6 is a medicine tank for accommodating therein, for example, powdery ammonium chloride 7 as a medicine. The medicine tank 6 is erected on a horizontal plate 9 fixed to a bracket 8 mounted so that the height position of the medicine tank 6 can be changed with respect to the column 3, and below the medicine tank 6. As shown in FIG. 2, there is provided a chemical drop port 10 through which the ammonium chloride 7 is dropped.

As shown in FIG. 2, the plate 9 has an opening 11 concentric with the medicine dropping port 10 and
A counterbore portion is formed on the lower side of the opening 11, and a heat resistant member 12 such as a heat resistant felt is fitted into the counterbore portion. As a material forming the heat resistant member 12, a material having heat insulating properties, heat insulating properties, and cushioning properties is preferable. In addition to the above heat resistant felt, for example, ceramic fibers, carbon fibers or the like can be used. The heat-resistant member 12 is also formed with a throttle opening 13 concentrically with the medicine dropping opening 10 and the opening 11. That is, the drug tank 6
The ammonium chloride 7 therein can be dropped downward through the medicine dropping port 10, the opening 11 and the aperture 13.

In FIG. 1 and FIG. 2, 14 is a plate-like member that rotates so as to contact the lower surface of the heat-resistant member 12, and is made of a material having chemical resistance and heat resistance, such as stainless steel, It is formed in a disk shape, and eight holes 15 ... Are provided so as to divide the circumference into eight equal parts, for example. The diameter of these holes 15 ... Is smaller than that of the aperture 13. The plate member 14 is a stepping motor 18 described later.
, The glass bottle 1 and the glass bottle 1 move in synchronization with each other by a predetermined angle (for example, 45 °), but when the hole 15 is within the diameter of the aperture 13, or Since the squeeze port 13 is opened while the squeeze port 13 overlaps the portion, the ammonium chloride 7 in the medicine tank 6 can fall, but the squeeze port 13 is a portion of the plate member 14 other than the holes 15 ... The ammonium chloride 7 does not fall when it is blocked by the portion 16.

Further, in FIG. 3, reference numeral 17 is a drive unit for rotating the plate-shaped member 14, and the drive unit 17 is provided with a stepping motor 18 and a bevel gear 19 at one end as shown in FIG. The output shaft 20 and a bevel gear 21 that meshes with the bevel gear 19 are provided at the upper end, and the plate-shaped member 14 is provided at the lower end.
And a drive shaft 22 for holding, as shown in FIG.
It is provided on the bracket 8 and the plate 9.

Further, in FIG. 3, reference numeral 23 indicates a position (detection position) where the glass bottle 1 moving from the back surface side to the front surface side in FIG.
A detector for detecting whether or not the stepping motor 18 has reached the detection position. For example, when the glass bottle 1 reaches the detection position, a predetermined signal is output from the detector 23, and based on this signal, the stepping motor 18 Operates and the plate-shaped member 14
Is configured to start rotating in a predetermined direction.

And as shown in FIG. 4, a part of the plate 9,
That is, a part of the upstream side of the medicine tank 6 as viewed in the rotation direction of the plate-shaped member 14 is notched, and this notch
As shown in FIG. 1, 24 is provided with an air blowing nozzle 26 that constantly blows compressed air 25 from above the plate member 14 toward the holes 15 of the plate member 14.

Thus, in the medicine feeding device 5 having the above-described configuration, the medicine dropping port 10 of the medicine tank 6 and the squeezing port 13 of the heat resistant member 12 are formed so as to correspond to each other.
Since the plate-shaped member 14 is stationary so as to close the aperture 13 by the shielding surface 16, the ammonium chloride 7 in the medicine tank 6 does not drop.

When the detector 23 detects the glass bottle 1 moving linearly at a predetermined detection position, a predetermined signal is output from the detector 23, and the stepping motor 18 rotates based on this signal. When the stationary plate-shaped member 14 starts to rotate by a predetermined angle and the aperture 13 is opened, the ammonium chloride 7 begins to drop.

The operation of the plate member 14 at this time will be described with reference to FIG. 4. In this embodiment, the plate member 14 may be rotated by 45 °, but the diameter of the aperture 13 is 30 mm and the plate member 14 is 14 mm. When the diameter of hole 15 ... is 4.5mm, the first 9 ° (α part in the figure)
Then, it accelerates, and at the next 27 ° (β part in the figure) it becomes constant speed,
It is sufficient to decelerate at the final 9 ° (γ portion in the figure), and at this time, about 0.07 g of a predetermined amount of ammonium chloride 7 could be put into the glass bottle 1. When the heat-resistant member 12 was provided with the aperture 13 having a diameter of 20 mm and the plate member 14 was rotated under the same conditions as above, 0.05 g of ammonium chloride 7 could be added.

And 7 ammonium chloride for 1 glass bottle
When the injection of is completed, the plate-shaped member 14 is stopped at a predetermined position again, and the shielding portion 16 closes the aperture 13, so that
The ammonium chloride 7 is prevented from falling.

In this way, when the ammonium chloride 7 is put into the glass bottle 1, the plate-shaped member 14 is rotated by a predetermined angle to open the aperture 13, so that the glass bottle 1 feed pitch becomes narrow. Can also accommodate this. Further, since the heat insulating material 12 is provided below the medicine tank 6, it becomes difficult for the heat radiated from the glass bottle 1 to be transferred to the medicine tank 6 side. It is prevented from solidifying at the squeeze port 13, and a predetermined amount of ammonium chloride 7 can be constantly and smoothly charged into the glass bottle 1. And, as mentioned above, the glass bottle 1
Since the heat radiated from the medicine tank 6 is less likely to be transmitted to the medicine tank 6 side, it is not necessary to cool the medicine tank 6 with cooling water or the like as in the conventional case, and accordingly, the entire apparatus can be made compact.

Further, in the above-described embodiment, the compressed air 25 is directed toward the hole 15 of the plate-shaped member 14 on the upstream side of the drug tank 6 as viewed in the rotation direction of the plate-shaped member 14, that is, on the upstream side of the drug feeding position. Since the holes 15 are cleaned by spraying, the holes 15 are not clogged, and a predetermined amount of ammonium chloride 7 can always be passed.

The present invention is not limited to the above-mentioned embodiment, but it is possible to put the medicine in a container other than the glass bottle 1, and it is also possible to use a medicine other than the above ammonium chloride. There is no end.

[Effect of device]

As described above, according to the present invention, it is possible to always and reliably and smoothly insert the medicine into the container, though the structure is compact. Further, even if the transporting speed of the container is the same, the dosage of the medicine can be easily adjusted only by replacing the plate-shaped member, which is extremely convenient.
