Description

Detailed Description of the Invention 3. Detailed Description of the Invention (Objective) The present invention relates to an improvement of a bottle washing device that automatically and continuously cleans the inside of bottles in a Hotling factory or the like.

Conventional automatic continuous bottle washing devices can be roughly divided into three types.The first type is a system in which a large number of rubber pads are attached to the inside of two series of parallel sprocket chains in a vertical position, and bottles are held from both sides, and the chain rotates. The inside of the bottle, which is in an inverted position, is sprayed out from a spray nozzle that is fixed downwards to clean the inside of the bottle. The material is fed into the twist, then turned 180 degrees, and as it passes through the fixed guide, it is cleaned from below by a fixed nozzle, and then rotated forward at the exit twist and sent to the discharge conveyor. A large number of pockets are attached at a constant pitch to a chain that rotates vertically in an ellipse, and the bottles sent on the conveyor are pushed into the pockets one after another by a pusher that synchronizes with the pockets, and the bottles are placed in an inverted position. This is a device that sprays washing water from a nozzle linked to a chain by a cam mechanism or the like at the bottom to wash each bottle individually. All of the above three types of bottle cleaning devices are currently in use, but in No. 1 and No. 2, the conveyance of the bottle and the nozzle are not synchronized, so most of the water sprayed does not enter the bottle mouth and is wasted. There are many. Also, if the bottle is soft, rubber pads and lateral pressure belts will not work.

Particularly in case 2, there is the inconvenience that the twist and fixed guide must be replaced each time the type of bottle is different.

Thirdly, the bottle and nozzle are synchronized, so water is not wasted, but the types of bottles are limited, and the equipment is complicated and expensive. The present invention provides a bottle internal cleaning device which has a simple mechanism and is inexpensive, in which the bottle and nozzle are synchronized so that washing water is not wasted, different types of bottles can be easily processed by simple replacement of parts. With the goal.

(Structure) Next, the structure of the present invention will be explained in the order of steps based on the drawings.
Bottles (3) arranged in one line and sent are transferred to a screw feeder (4) connected to a carry-in conveyor, and a constant pitch is given to the bottle openings. The bottle passes from the screw feeder to the inlet star wheel (5), which has several semicircular notches (6) whose pitch is equal to the trough of the screw feeder, and the bottle passes through the wheel (5).
) is guided by a transfer guide (7) K installed along the half circumference of the wheel, fits into the semicircular notch (6), and is gripped by a gripper (8) when the wheel has been sent half a circumference. Gripper (8)
are the driving sprocket (9) and the driven sprocket) (10
) A plurality of chains (11) are attached to the chain (11) at the same pitch as the semicircular notches (6) of the wheel. It has an arm (13). When the opening/closing claw (12) is opened by the claw opening/closing guide (14) provided close to the gripper and grips the bottle opening of the bottle fed on the wheel (5),
A reversing arm (1) screws into the opening/closing claw via a spring (15).
3) is guided by the bottle inversion guide (16) extending in an arc from the wheel (5) to the periphery of the drive sprocket (9), and rotates 1800 degrees around the bottle (17), so that the bottle held therein is in an inverted position. to make half a turn around the driving sprocket (9). Around the drive sprocket, there is an injection nozzle (18
) have a plurality of openings, the bottle opening and nozzle (18) rotate with the rotation of the sprocket, and the inside of the bottle is thoroughly cleaned during half a rotation of the sprocket. Cleaning water is supplied from a fixed water supply pipe (19), and is supplied to a water distribution pipe (22) fixed to the drive shaft via a rotor seal (21) attached to the drive shaft (20) of the drive sprocket. - and is ejected from the nozzle (18). Once the inside of the bottle has been cleaned, hold it in an inverted position using the gripper (8
), and as the chain (11) rotates, the driven sprocket (10) reaches K, and while the chain (11) rotates halfway around the sprocket, it is assisted by the bottle royal guide (23) K and assumes the royal position, and the transfer guide (7) an exit starwheel (24) rotating oppositely to said inlet starwheel (5) along K;
, and then transferred to the carry-out conveyor (25) and sent to the next process.

(Effects) In the present invention, the spray nozzle is attached to the mouth of the inverted bottle, so the washing water enters the bottle without wasting it, and the washing time per bottle is longer than the conventional model, so the washing effect is large. The usage amount can also be significantly reduced. Unlike the rubber pad type or lateral pressure belt type, the bottle hold system does not apply pressure, so soft bottles can also be processed, and different types of bottles can be easily cleaned by simply replacing parts. Since it has a compact structure, it can be manufactured at a relatively low cost and is easy to manage.
