DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device for a wooden log that removes mold and the like that inhabit the surface of an artificial wooden log having irregularities.

[0002]

2. Description of the Related Art In the process of manufacturing artificial log trees, molds are liable to be formed on the surface of the wooden logs due to invasion of various bacteria generated during the culture because the culture is performed in an environment containing a lot of moisture. If this mold is left untreated, the nutrients contained in the wood will be deprived by the mold, weakening the mushroom-producing mushrooms and reducing the yield.

[0003] For this reason, it is necessary to remove the mold that inhabits the surface of the tree. However, it is difficult to completely remove the mold, because the mold is irregularly generated on the entire surface of the wooden board and easily inhabits the thin cracks on the wooden board. Therefore, conventionally, the mold has been removed and washed manually by using a brush while checking the mold status of each of the trees.

[0004]

However, in the conventional method of cleaning with a brush, the brush ends do not reach a fine point, leaving behind mold and overlooking the mold, resulting in uniform mold and the like. It could not be removed. In addition, the method of rubbing with a brush may damage the surface of the wooden tree, causing mold attached to the brush to adhere to the scratch, causing a quality problem. In addition, the manual method not only causes mold oversight and variation due to individual differences, but also requires a long time for mold removal, resulting in low productivity.

[0005] Further, even if an automatic device using a brush is developed, as described above, problems such as secondary contamination due to a small cleaning brush have not been solved. Furthermore, in the method of spraying water from the nozzle, simply spraying the washing water not only cannot sufficiently remove the mold that inhabits the uneven wood, but also if the cleaning order is wrong, the mold may be removed. There was a problem of causing secondary contamination.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-mentioned problems of the prior art, and provides a cleaning device for a rope tree which is free from secondary contamination of mold due to the cleaning means and can remove even a small amount of mold. With the goal.

[0007]

SUMMARY OF THE INVENTION An object of the present invention is to provide a cleaning apparatus for cleaning a surface of a rugged tree having irregularities in a conveying process, wherein at least two or more groves are introduced into a cleaning chamber.
Equivalent to the upper loading conveyor, the gap between the loading conveyors
At least two unloading conveyors running along the
A lower cleaning device which is provided at each position of these conveyors and injects liquid upward from the lower part toward the log being conveyed, and an upper cleaner which injects liquid downward from the upper part of the log This is achieved by a scrubber cleaning device in which the devices are connected in series, respectively, downstream into the cleaning chamber. In addition, by adding a fungicide that kills mold to the liquid to be sprayed, the mold can be more reliably removed.

[0008]

In other words, the washing apparatus for a wooden groin according to the present invention ejects a liquid upward from the bottom toward the wooden groin at each position where the transport mounting surface is shifted during the transportation of the wooden groove. A lower cleaning device for the tree and an upper cleaning device for ejecting liquid downward from above the tree are connected in series downstream of the lower cleaning device. The location of the mold that inhabits the rope is concentrated on the top and bottom of the rope.

[0009] This is because the top surface of the tree has irregularities, so that water droplets sprayed during the culture remain, and various bacteria infest there.
In addition, since the side of the tree is cultivated by filling the tree into a container, the side has a smooth shape that is almost the same as the inner shape of the container, and the sprayed water drops flow down. The contained germs are also washed down. For this reason, mold is difficult to grow on the side surface. Also, the underside of the hike is
As water accumulates, it becomes a hotbed of mold, just like the top. Therefore, by adopting the above-described configuration of the cleaning device, the top and bottom surfaces of the wooden tree are concentrated, and the liquid is ejected from nozzles having various angles in consideration of the uneven shape of the wooden tree. Therefore, it is possible to remove the mold that inhabits in detail and wash it away. In addition, since the lower surface is cleaned by changing the mounting surface of the wooden tree, there is no blind spot zone for cleaning.

Further, since the mold is washed from above at the end of the washing, all the mold caused by the so-called secondary contamination generated during the washing is washed down, so that all the molds and the like are removed after the washing is completed.

[0011]

An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is an external view of a cleaning device for a wooden tree according to the present invention. In the drawing, reference numeral 1a denotes an uncleaned rope that is carried in by a carry-in conveyor 10, and firstly, the lower part of the rope is cleaned by a lower cleaning device 3 by passing through a cleaning chamber 2, and then an upper cleaning device. The upper part is washed by 4, and the washed tree 1 d is carried out by the carry-out conveyor 20.

These devices 2, 3, 4, 10, 20 are:
The washing water, which is mounted on the base 11 assembled at an angle and is washed, is collected at a trumpet-shaped hopper 12 at a lower part of the base 11 and discharged to the outside through a discharge port 13. . The washing chamber 2 is provided to prevent the washing water from scattering to the outside. The bellows curtains are provided at the entrance side and the exit side of the tree 1a to prevent the scattering of the washing water and to carry the tree 1a in and out. You can do it.

The lower cleaning device 3 is disposed upstream of the cleaning chamber 2 and is provided with a lower spray nozzle at an intermediate point of connection between the carry-in conveyor 10 for carrying the timber 1b and the carry-out conveyor 20. , 20 below, nozzles 21a, 21d for cleaning the bottom surface of the tree 1b, 21b, 21c, 21e (not shown), 21 for cleaning the side surfaces.
f is provided, and molds and the like invading the wooden board 1b are washed away with appropriate water pressure.

The nozzle 21d is connected to the loading conveyor 1
This is for cleaning the bottom surface of the hanging tree which is placed at 0 and becomes a blind spot for cleaning, whereby the entire bottom surface of the hanging tree 1b is cleaned. Although not shown, the cleaning water supplied to these nozzles 21a to 21f is supplied by a known water supply means capable of adjusting the water pressure.

Next, the upper cleaning device 4 is disposed downstream of the lower cleaning device 3, and is provided with a nozzle on the circumference of the rope 1c in order to clean the top surface of the rope having irregularities in detail. 41
a to 41f are provided so that the washing water is applied from all angles. In addition, in the washing of the wood, finally, washing from above is performed, so that the mold that is washed out by the lower nozzle and adheres to the side of the wood, etc., which is the so-called secondary contamination, is completely washed off and completely washed. You can do. Figures 2 and 3
The state diagram of the cleaning step is shown in FIG.

Next, the operation will be described. The tree supplied by the carry-in conveyor 10 is washed by the lower spray nozzle 21 and delivered to the next carry-out conveyor 20.
For the lower spray nozzle 21, the nozzle 21a cleans the bottom surface and the nozzles 21b, 21c, 21e, and 21f clean the bottom surface and side surfaces of the wood 1b sent from the carry-in conveyor 10. At that time, the carry-in conveyor 10 and the carry-out conveyor 20 are arranged in series at a position intermediate between the nozzles 21a and 21d, and the products are transferred from the carry-in conveyor 10 to the carry-out conveyor 20. The bottom surface of the carry-out conveyor 20 is cleaned by the nozzle 21a from below while the carry-in conveyor 10 conveys the wood 1b, but the bottom surface of the wood 1b on the conveyor is a blind spot for washing by the chain. Therefore, in order to clean the blind spots by the carry-in conveyor 10, the ropes 1c are transferred to the carry-out conveyor 20. Therefore, the portion of the bottom surface in contact with the chain is changed, and thereafter, the bottom surface is cleaned by the nozzle 21d, whereby the blind spot formed by the carry-in conveyor 10 is cleaned, whereby the entire bottom surface can be cleaned. The upper spray nozzles 41 wash the top surface and side surfaces of the logs 1c sent from the carry-out conveyor 20 after the nozzles 41a first clean the top surface and then wash water on each uneven portion of the top surface with the nozzles 41b to 41f. Enter 50 and wash out the mold that inhabits the details, while flushing it down.

In the above-described embodiment, the same washing is described, regardless of the amount of mold generation. However, in the actual cultivation of the tree, the occurrence of mold is specified. There is a tendency that some molds with a large amount of mold generation and some with a small mold generation tend to be supplied as a group, such as concentrating at the place where they were cultured in the place of the cultivation. The conveyor speed and nozzle pressure are adjusted according to the amount of mold. In other words, by slowing down the conveyor speed and increasing the water pressure of the nozzles for logs with a large amount of mold, and automatically changing the washing conditions according to the amount of mold, it is more reliable than uniform washing. In addition to removing mold, water consumption can be reduced.

Further, the nozzle pressure may be adjusted individually. In addition, if the water sprayed from the nozzle is capable of spraying fine mist-like particles, the cleaning water can penetrate into the details and can be more reliably cleaned. Further, by adding a fungicide to kill the mold to the washing water, the washing effect can be further enhanced. Further, after the washing is completed, high-pressure air may be sprayed on the wood 1d to drain the water.

[0019]

As described above in detail, the cleaning device according to the present invention firstly cleans the lower part of the timber, cleans the upper part after cleaning while changing the mounting surface of the timber. As a result, there is no unwashed part of the log and
Problems due to secondary contamination are also eliminated.

In addition, since the nozzles are arranged in consideration of the shape of the rope to be cleaned and the occurrence of mold, it is possible to clean every corner without damaging the rope. . As a result, it is possible to prevent a decrease in the yield of the mushrooms due to inadequate washing, and it is possible to obtain a uniform quality roasted tree.
