Abstract

PURPOSE:To prevent leakage of alcohol through sealed section when sealing with a cork by lowering a guide and a rotary polishing cutter thereby forming a right-circle polishing face on the inercircumferential face of bottle mouth through rotation of said cutter. CONSTITUTION:Upon lifting of the bottle mouth 23 toward a guide 7 and pushing a guide 7, it is held in parallel to support the bottle mouth 23 with said guide 7. Under this state, the bottle 22 is suspended standstill to align the centerlines of the bottle mouth 23 and the spindle 6. Upon lowering of the spindle 6 to contact the bottom of bottle against a horizontal table 27, said guide 7 will slide on the innerface of the bottle mouth downwardly to contact the reverse-conical face of the rotary polishing cutter 15 against the inercircumferential face of the bottle mouth to be polished into right-circle circumferential face having the center on the centerline of spindle 6. Consequently, leakage of alcohol through the section sealed with a cork can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application" The present invention relates to a method and apparatus for circularly polishing the inner peripheral surface of the mouth of a bottle or bottle containing alcoholic beverages.

``Prior art'' Conventionally, it is difficult to form the inner circumferential surface of glass or ceramic bottles or bottles for wine, alcohol, whiskey, shochu, etc. into a perfect circle, and the bottle is slightly deformed due to thermoplasticity during the manufacturing stage. Therefore, even if the cork stopper is fitted, alcoholic beverages will leak from the deformed part. For this purpose, the outside diameter of the cork stopper is made larger and longer than the inside diameter of the bottle mouth, and the cork is strongly compressed to fit into the bottle mouth, or the bottle is turned upside down after entering the bottle and the alcoholic beverage is inserted into the cork stopper. It is necessary to moisten and expand the bottle, and even then, the yield of bottles is low due to poor bottle necks.

``Problems to be Solved by the Invention'' The purpose of the present invention is to polish the inner circumferential surface of the mouth of a glass or ceramic liquor storage bottle into a perfect circle and seal it with a cork stopper to prevent leakage from the sealed part. It is something.

``Procedures and means for solving the problem j The present invention supports a plurality of bottle opening insertion guides in a tiltable manner at the lower end of a vertical spindle that is provided on the machine frame and can be freely raised and lowered, and the upper part of the guide is supported by the force of the spring. Using a polishing machine with a spindle equipped with a rotary polishing blade with an inverted conical surface on the top of the guide, lift the bottle with the spindle raised and grind the bottle slightly inside the outside diameter of the upper end of the guide. A step in which the bottle mouth with a small diameter is fitted onto the guide and the bottle is suspended from the guide, and then the spindle is lowered to bring the bottom of the bottle into contact with the horizontal table, and the spindle is further lowered to The present invention is constituted by a bottle mouth polishing method and an apparatus thereof, characterized in that a guide and a rotary polishing blade are lowered and the inner circumferential surface of the bottle mouth is ground by rotation of the same blades.

"Function" Therefore, when the bottle spout 23 is lifted toward the guide 7 from diagonally below the raised guide 7 and the guide 7 is pushed into the bottle spout 23, the guide resists the force of the spring 12 and guides 7 are parallel to each other, the guide 7 is pressed against the inner peripheral surface of the bottle mouth, and the bottle mouth 23 is supported by the guide 7. In this state, when the bottle 22 is suspended, the center lines of the bottle mouth 23 and the spindle 6 coincide. In this state, when the spindle 6 is lowered and the bottle bottom 26 touches the horizontal stand 27, the guide 7 slides downward on the inner surface of the bottle mouth, and the inverted conical surface of the rotary polishing blade 15 comes into contact with the inner peripheral surface of the bottle mouth. The inner circumferential surface is a perfect circular circumferential surface 2 centered on the center 1a of the spindle 6 by the surface polishing blade 15.
Polished to 4. After that, hold the bottle 22 and press the spindle 6.
When the abrasive blade 15 and the guide 7 are raised, the polishing blade 15 and the guide 7 are also raised above the bottle mouth, and this process can be repeated.

``Example'' The lifting shelf frame 3 that moves up and down along the vertical guide rods 2.2 is supported on the fixed machine frame l by the force of the springs 417), and the machine frame 3 is moved against the springs 4 by operating the manual lever 5. can be lowered and raised to the original position 1a by the force of spring 4. This machine frame 3 is provided with a vertical water supply spindle 6 fixed in the rotational direction, and a plurality of bottle spout insertion guides 7, 7 can be tilted at the lower end of the spindle 6 by means of a pin 8 or a universal joint 9 (Fig. 6). support.

A horizontally elongated hole 1) is bored in the support fitting 1o provided in the middle of this guide 7.7.The pin 8 is slidably inserted into the elongated hole 1) (Fig. 9), and the The guide 7.7 is rotatable, and the upper part of the guide 7.7 is opened slightly outward by the force of the spring 12, and the lower end protrusion 13 of the guide 7.7 is held in this state.
．． 1'3 are brought into contact with each other to determine the opening angle of the guide 7.7. At the upper part of the guide 7.7, a rotary polishing blade 15 made of diamond brazed onto an inverted conical surface is provided concentrically with the spindle 6 and fixed in the sliding direction. This polishing blade 15 is provided at the lower end of a rotary cylinder 16 fitted to the spindle 6, and is rotated by a vJtlI belt 18 which is wound around a pulley 17 provided at its upper end. 19 in the figure is a water supply hole, 20 is an abrasive powder discharge groove, and 21 in FIG. 14 is a bottle mouth protrusion.

"Effect" Since the present invention is based on the above-described method and apparatus, the bottle 22 can be grasped by hand and the bottle mouth 23 can be easily opened from the guide guide 7 from below.
．． 7, and by removing the hand and suspending it, the center lines of the rotary blade 15 and the bottle spout 23 can be easily aligned, and a perfectly circular polished surface 24 can be easily formed on the inner peripheral surface of the bottle spout. As a result, the cork stopper 25 can be fitted tightly, there is no leakage of alcoholic beverages, and defective bottles can be effectively utilized.
