JPH05281A - Apparatus for washing bottle - Google Patents

Abstract

PURPOSE:To wash the inside and outside of a bottle by rapidly peeling off the label bonded to the bottle when the recovered bottle is reused by a method wherein the recovered bottle is inverted to be sunk in a high temp. liquid while the air in the bottle is drawn out by an air venting tube and a washing solution is injected to the bottle from below after the tube is pulled out. CONSTITUTION:An erected recovered bottle A is received in a basket 1 to be inverted to direct the mouth of the bottle downwardly and the air suction tube 4 waiting in such a state that the leading end thereof is slightly put out from the surface of the hot water in a high temp. immersion tank 3 is inserted in the bottle A to sink the bottle and air is removed from the bottle. Subsequently, the tube 4 is removed and the basket 1 is moved toward the outlet of the tank 3. This operation is repeated. After the bottle is immersed for a definite time, the bottle is taken out of the hot water to be subjected to finish washing by the washing solution injected from a jet nozzle 9. The basket 1 is again reversed to discharge the bottle in an erected state and returned toward the inlet of the tank 3. As a result, when the recovered bottle is reused, the bonded label is rapidly peeled off to make it possible to wash the inside and outside of the bottle. Further, the washing machine can be miniaturized.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bottle cleaning apparatus for peeling a label of a glass bottle which has been used once, cleaning the same and reusing it.

[0002]

2. Description of the Related Art Conventionally, washing is performed by dipping bottles in several tanks having different temperatures, or by repeatedly injecting a washing liquid which gradually raises the temperature.

[0003]

This has the following drawbacks. (B) To clean the bottle, it is effective to immerse it in a high-temperature liquid or to inject a high-temperature liquid at high pressure, but if it is suddenly exposed to a high temperature, a temperature difference will occur between the inside and outside of the bottle, which may cause distortion. You have to gradually raise the temperature as the bottle will break. Therefore, a number of dipping tanks or jetting tanks are required, and it takes a long time to wash, so a large number of bottles must be retained in the machine, and they must be taken out after the work is completed. (B) Since many tanks were required, the machine became huge and required a large installation area. (C) Since the machine is huge, the manufacturing cost of the machine is high.

[0004]

[Means for Solving the Problems] (a) One high temperature immersion tank. (B) Insert the basket (1) into the bottle and turn it upside down. (C) The basket is immersed while inserting the bottle mouth into the air vent tube (4) standing by in the dipping tank and inserting it into the bottle. (D) Remove the air vent tube and move the basket toward the outlet. (E) Raise the basket, remove it from the high temperature liquid, and send it to the jet cleaning chamber. (F) After the jet cleaning process and the rinsing process with warm water, the basket is inverted, the bottle is erected upright, and the basket is pulled out. (G) Move the bottle to the discharge conveyor and the basket to the inlet side.

[0005]

[Function] When the bottle is inverted and the air inside the bottle is submerged in the high temperature liquid while bleeding the air inside the bottle with the air bleeder tube (4), the liquid level inside the bottle and the liquid level outside remain the same. When hitting the hot liquid from one side, the hot liquid expands and the bottle breaks. It is said that the limit temperature difference is about 40 degrees Celsius, but the bottle breaking temperature difference becomes smaller as the bottle deteriorates. In the case of the present invention, since the inside and outside of the bottle are heated at the same time, distortion does not occur in the bottle, so that the bottle is not damaged even if it is immersed in high temperature suddenly.

EXAMPLES Examples of the present invention will be described below. (A) The sewage bottles (A) group transferred by the conveyor (12) are aligned at equal intervals by the machine entrance split wheel (13) and are driven by the planetary gears (14), (15) (1)
In 6), an independent basket (1), which is moved onto the inlet plate (17) and holds the bottles laterally at equal intervals, is lowered by the rod (18) to fit into the upright bottle,
After moving with the feed rod (7), the roller (2) attached to the basket is used as a fulcrum to turn upside down by the motor (8) and lowered by the arm (30), and the tip is brought to the liquid surface in the high temperature immersion tank. Air vent tube (4) to stand by
Is guided by the guide cone of the basket (1) and inserted into the bottle, and is lowered until the tip of the air vent tube reaches the bottom of the bottle, and then the air vent tube is lowered and removed from the bottle.
The arm (30) and the bleeder tube are driven by the air cylinder, but a cam has the same effect. The air vent tube is connected to the pipe and fixed to the elevating arm (31), but the pipe (32) is connected to the vacuum pump through the flexible tube (33) outside the can body and the cutoff valve to connect the tube (4) pipe. At (32), the accumulated liquid and air are taken out of the machine. (B) When one basket is dipped and the air vent tube is pulled out, the basket is moved by one basket in the direction of the outlet while pushing the previously dipped basket by the rod (20). By repeating such operation, several baskets stayed in the dipping tank for a certain period of time, then reached the outlet side, jetted the liquid from the jet nozzle (9) below the basket to the upper side, and were stuck to the bottle by the high temperature liquid. The label glue dissolves and falls off, and the label that remains in the basket is blown up and discharged to the outside through the slit (21) of the basket. The label discharged from the basket is sucked into the label suction cylinder (11) having a structure in which the suction port moves, and is taken out to the outside to be separated. The suction port is moved by the label suction cylinder (11) and the label suction inner cylinder (10). The outer cylinder is opened in a straight long hole and fixed in the suction direction, and the inner cylinder is spirally formed. It sucks while making a long hole and slowly rotating it in the outer cylinder. It is strong locally and sucks from the entire width. When taking out the bottle from the dipping tank, insert the air tube (22) into the bottle and take it out while sending air, but the air tube is taken out of the machine by the flexible tube and the check valve and shutoff valve are sandwiched and connected to the compressed air tube. To be done. (C) When the basket is taken out, it is placed in the jet cleaning chamber by the bar (23). In the spray cleaning chamber, a plurality of baskets stay, and while moving intermittently, the outer cleaning nozzle (5) and the inner cleaning nozzle (6) are circulated by a circulation pump at 6 degrees Celsius.
The cleaning liquid is injected around 0 degree, and finally rinsed by the injection of clean hot water, delivered to the reversing section, the basket is inverted again and delivered to the discharge plate (26), and the basket is pulled up. The bottle standing upright on the discharge plate is delivered to the discharge conveyor (28) by the discharge lever (27). The raised basket (1) is attached to the transport chain (2
It is a bottle cleaning device that is sent to the inlet side in 9) so as to prepare for capturing the next bottle.

[0007]

(A) The higher the temperature of the bottle, the higher the cleaning efficiency. However, the present invention enables the temperature to be raised in an extremely short time and the cleaning time can be shortened remarkably. (B) Since the temperature is high, the label can be peeled off easily, and it is no longer necessary to add detergent to the cleaning liquid. (C) Since the cleaning time is short, the bottle to be retained inside the machine can be made extremely small and the installation area is small, and the machine manufacturing cost is low. (D) The label is not high-pressure jetted by the nozzle, and is naturally peeled off at a high temperature, so that the jetting nozzle that circulates and jets by the shredded label scraps is not clogged, and there is no reduction in efficiency therefor. (E) At the end of the work, the bottles remaining in the machine must be taken out, but the machine is small and the number of retained bottles is small, so that the bottles can be processed promptly.
