Abstract

PURPOSE: To remarkably reduce the dipping treatment time necessary for the removement of a label and the washing sterilization, by mounting a label removing device having a bottle guide for guiding the bottles, and a nozzle for inclining the high-pressure water toward a peripheral face of the bottle, on a bottle supply path for sending the bottles in the almost horizontal attitude. CONSTITUTION: A bottle 7 sent from a bottle supply conveyor 10 to a bottle supply guide 17 through a bottle supply device 9, is rotated in the circumferential direction by the rotation of a rotary guide bar, and pressed by a rod 25 of a bar conveyor 18 to be moved on the bottle supply guide 17. The high- pressure washing water is jetted toward the bottle 7 from the upper part by a nozzle 19, whereby a label 7a is separated. On this occasion, the separation of the label 7a is accelerated by the resistance of the knurl or the like on the guide bar peripheral face which is kept into contact with a peripheral face of the bottle 7. The bottle 7 from which the label 7a has been separated, is inserted into a carrier basket 8 on a bottle supply position from the bottle supply guide 17, and the bottle 7 held by the carrier basket 8 is washed and sterilized through the washing tanks 1, and discharged from a bottle discharging portion 4.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a bottle washing machine for washing labeled bottles.

BACKGROUND OF THE INVENTION Conventionally, a bottle washing machine for washing labeled collection bottles uses a bottle feeding device RA 41 as shown in FIG. Cleaning, sterilization, and label peeling were performed by sequentially dipping and passing through a tank.

Problems to be Solved by the Invention However, with the conventional method mentioned above, the soaking time for bottles without labels is about 10 minutes, while for bottles with labels it takes much longer, about 16 minutes. It has been desired to shorten the soaking time required for cleaning and sterilizing labeled bottles.

SUMMARY OF THE INVENTION An object of the present invention is to provide a bottle washer that can solve the above-mentioned problems and significantly shorten the immersion time required for label removal and cleaning and sterilization of labeled bottles.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a system for supplying bottles from the discharge side of a bottle feeding device that feeds out bottles in a substantially horizontal position to a basket that holds the bottles and passes through a washing tank. A configuration in which a label removing device is provided in the bottle path, which includes a bottle feeding guide that guides the bottle, a transfer means that moves the bottle along the bottle feeding path, and a nozzle that sprays high-pressure water toward the circumferential surface of the bottle. That is.

Effect With the above configuration, all or most of the label can be peeled off and removed before being immersed in the cleaning layer, so the subsequent immersion treatment time in the cleaning tank can be significantly shortened, and the label can be removed by high-pressure water from the nozzle. Preliminary external washing is possible, allowing cleaning of areas that are relatively difficult to clean, such as wood grain.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 4.

FIG. 2 is a side cross-sectional view showing the entire washing machine.

In Fig. 2, reference numeral 1 denotes a plurality of cleaning tanks provided in the main body 2 of the plate crane, and each of these washing tanks 1 includes a bottle feed section 3 at the front of the plate crane main body 2 and a bottle discharger at the rear. An endless chain 6 wound around a sprocket wheel 5 between the chamber 4 and the chamber 4 is configured to pass therethrough, and a number of carrier baskets 8 for holding bottles 7 are attached to the chain 6.

Reference numeral 9 denotes a bottle feeding device disposed in the bottle feeding section 3. As shown in FIG. It is configured to be transferred by the arm 13 along an arcuate guide 14 and sent out in a substantially horizontal position.

Reference numeral 15 denotes a label removing device disposed in a bottle feeding path 16 from the discharge side of the bottle feeding device 9 to the carrier basket 8 at the feeding plate position, and is used to remove labels from the bottom of the bottles 7 in a horizontal position discharged from the bottle feeding device [9]. A bottle feed guide 17 that supports the circumferential surface and has a rotation function that rotates the yIA7 in the circumferential direction, and 317
a bar conveyor 18 (transfer means) that conveys the bottles along the bottle supply guide 17 in the height direction, and a plurality of label removing devices that are disposed above the bottle supply guide 17 and spray high-pressure water toward j17. It is equipped with a nozzle 19. As shown in FIGS. 3 and 4, the bottle feeding guide 17 includes a plurality of fixed guide bars 20 and rotating guide bars 21 arranged alternately along the bottle feeding path 16. The fi7 supported between the rotating guide bars 21 is a rotating drive device! <not shown) by arrow a
By being rotated in the direction indicated by the arrow, it is rotated in the direction indicated by the arrow. Furthermore, a low left 22 or the like may be formed on the circumferential surface of each guide bar 20, 21 to make it easier to peel off the label 7b. The bar conveyor 18 has a transfer rod 2 that can come into contact with the bottom of the bottles 7 between endless chains 24 that are wound around front and rear sprocket wheels 23 on both sides of the bottle feeding path 16.
A plurality of numbers 5 are arranged.

A plurality of the nozzles 19 are arranged downward along the upper part of the bottle feeding guide 17, and the cleaning water sprayed from the nozzles 19 is added with a chemical or the like so that the label 7a can be easily peeled off. In addition, the peeling effect can be enhanced by using hot water, and the washing water after spray washing is collected in a collection tank 26 disposed below the bottle supply path 16, and is sent from the collection tank 26 via a label collection device 27. The purified cleaning water is sent to each nozzle 19 by a high-pressure pump 28 via a high-pressure water supply 'i29.

Next, the effect will be explained.

The bottle 7 to be cleaned is cleaned in order to enhance the peeling effect of the label 7a.
Before supplying, water is sprayed to make the label 7a moist, or before water is sprayed, a light beam such as a laser is applied to make the label 7a easy to peel off. Then, the bottle 7 sent from the bottle feeding conveyor 10 onto the bottle feeding guide 17 via the bottle feeding device 9 is rotated in the circumferential direction by the rotation of the rotating guide bar, and is also rotated by the rod 25 of the bar conveyor 18.
It moves on the bottle supply guide 17 by being pushed by. Then, high-pressure cleaning water is jetted from the nozzle 19 toward @7 from above, and the label 7a is peeled off. At this time, the peeling of the label 7a is promoted by the resistance of the knurls 22 and the like on the circumferential surface of each guide bar 20 and 21 that come into contact with the circumferential surface of the bottle 7.

The bottle 7 from which the label 7a has been peeled off is inserted into the carrier basket 8 at the feeding plate position from above the bottle feeding guide 17, and the bottle 7 held in the carrier basket 8 passes through each washing tank 1 and is washed and sterilized. After that, it is discharged from gf111 section 4.

On the other hand, the cleaning liquid collected in the collection tank 26 together with the peeled off label 7a is collected by the label collection device r! After the label 7a is removed by 127, it is supplied again to the nozzle 19 via the high-pressure pump 28 and circulated.

In addition, in the label removing device of the above embodiment, the bottle feeding guide 1
By the rotation guide bar 21 of 1! ! Although the bottle 7 is rotated in the circumferential direction, the bottle 7 may be rotated using the jet pressure of high-pressure water from the nozzle 19, as shown in FIG. That is, this label removing device 31 supports the bottle 7 on a fixed guide 32 having a protrusion 32a, and supports the bottle 7 on the circumferential surface of 1!7 from a position deviated by a predetermined distance g laterally from the center line A of the bottle 7. A flat nozzle 33 that sprays high-pressure water directly below the side is provided, and the spray pressure of the high-pressure water rotates the bottle 7 in the direction of arrow C and peels off the label 7b. The flat nozzle 33 used has an ejection surface that is long in the length direction of the feeding plate guide 34 and narrow in the width direction.

Effects of the Invention As described above, according to the present invention, the label can be peeled off and removed from the bottle using high-pressure water from the nozzle in the bottle feeding path before washing in the washing tank, so that the soaking time in the subsequent washing tank can be reduced. It is possible to significantly shorten the time and reduce the number of cleaning tanks, making it possible to downsize the plate-cutting machine.In addition, the number of label processing devices that were conventionally required for each cleaning tank can be reduced. In addition, the high-pressure water from the nozzle can also be used to remove shoes that are relatively difficult to clean.
