Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coating device for forming a uniform coating film on the surface of agricultural products such as eggs, apples, tangerines, etc. in a short time and over a short distance.

Agricultural products are natural products and living things, so if they are harvested in their natural state, they do not look good due to dirt, etc., and are difficult to withstand long-term storage. After drying, it is common practice to coat the material with a coating liquid such as a storage improver or a release agent such as wax.

Conventional coating equipment, such as JP-A-54
The coating device disclosed in No. 25757 includes an egg conveyor that gently rolls the eggs in a lying position, a rotating brush that runs along the upper side of the egg conveyor, and a rotating brush that is installed near the transfer start point of the egg conveyor. It consists of a fat and oil supply device, and in particular, as a means of gently rotating the eggs while transporting them, the eggs are placed on a rail-shaped or gutter-shaped passage and pushed and fed to cause the eggs to rotate on their own axis. Alternatively, it is stated that it is simple and effective to use a rotating roller structure for the egg tray itself that houses the eggs, and to transmit the rotation to the eggs. However, even when the coating liquid is transferred from the oil supply device to the rotating brush, the eggs transported by the egg conveyor are only gently rotating, so the rotating brush transfers the coating liquid to the entire surface of the egg. In order to form an even and uniform thin film, a long coating device is required to match the slow rotation of the eggs, making the equipment large-scale.Moreover, the coating process takes a lot of time and requires a lot of time and effort. It's efficiency.
Therefore, the above device is too large to be used as a part of an extremely simple and short egg washing device, and the above device must be adopted as a separate component next to the egg washing device. There must be.

Since conventional coating devices have various defects as described above, the present invention eliminates these defects by the structure described in the claims for utility model registration, and makes it possible to form a spherical, ellipsoidal, or similar shape. The present invention aims to provide an apparatus that can rapidly, easily, inexpensively, and continuously form a uniform coating film on the surface of agricultural products such as fruits, fruit vegetables, bulbs, root vegetables, eggs, etc.

Examples regarding chicken eggs will be described below.
The coating device of this embodiment includes a conveyor that transports eggs, a rotating brush that rotates while sliding on the surface of eggs, a supply device that supplies coating liquid to this rotating brush, and forced rotation of eggs through a carrier. It consists of a forced rotation device.

As shown in FIG. 1, the conveyor 1 has two endless chains 2, 2 suspended between a driving sprocket and a driven sprocket, which are rotatably mounted on the machine frame, and two endless chains 2, 2, 2, and an appropriate number of carriers 3 rotatably supported parallel to each other at appropriate intervals. The carrier 3, which is pivotally supported between the endless chains 2 and 2, is made up of two adjacent chains each having an appropriate number of drum-shaped parts fixed at regular intervals to the shaft center of the carrier 3. The hourglass-shaped parts of the carriers 3, 3 are provided so as to face each other, and the egg-shaped part 4 is laterally fitted into the insertion part formed by the hourglass-shaped parts facing each other, and is supported by the two hourglass-shaped parts. When the carrier 3 is transferred, a plurality of rows of eggs 4 are simultaneously transferred.

The forced rotation device 5 is located below the transport conveyor 1, and has a belt 6 suspended between a driving drum 7 and a driven drum 8 which are pivotally supported on a machine frame. The upper circumference of the belt 6 is driven by a drive drum 7 in a direction opposite to the traveling direction of the conveyor 1 as shown by the arrow. The upper connecting surface of the belt 6 is in sliding contact with the lower surface of the carrier 3, and drives the carrier 3 to rotate in the direction of movement of the belt. Since the egg is supported by this carrier 3, the rotation of the carrier causes it to rotate in the opposite direction to the carrier as shown by the arrow. In order to prevent the belt 6 from being bent between the drive drum 7 and the driven drum 8 and unable to come into sliding contact with the carrier 3 at that portion, one or more guide drums are provided between the two drums 7 and 8. 9 is pivotally supported on the machine frame, or a guide plate (not shown) is fixed to the machine frame to prevent deflection of the belt 6 by sliding the upper and lower surfaces of the belt 6 into sliding contact.

Furthermore, in order to rotate the carrier 3, substantially the same effect can be obtained by using a chain instead of the belt 6 described above. Its structure is as follows. A small sprocket is fixed to one end of the carrier 3, and a chain that is placed above or below the sprocket and can move while meshing with the sprocket is suspended from a driving sprocket and a driven sprocket that are pivotally supported on the machine frame. If necessary, if a guide sprocket is pivotally supported on the machine frame between the driving sprocket and the driven sprocket, deflection of the chain can be prevented, the meshing between the chain and the small sprocket can be improved, and forced rotation of the egg 4 can be ensured. Become.

The coating liquid supply device 10 is fixed to the machine frame, and includes a coating liquid tank 11 that stores the coating liquid, a supply drum 12 that rotates with a part of its lower surface immersed in the coating liquid, and The scraper 13 is fixed to the machine frame so as to be in sliding contact with the surface. The supply drum 12 is rotatably supported on the side wall of the tank 11 in parallel with the carrier 3. The coating liquid adhering to the surface of the supply drum 12 is scooped up by a scraper 13, flows down the upper surface of the downwardly inclined scraper 13, and an appropriate amount of the coating liquid is supplied to a rotating brush 14 in contact with its lower end. Supply drum 1
Rotating brush 1 by adjusting the rotation speed of 2.
Adjust the amount of coating liquid transferred to Step 4. The rotating brushes 14 and 15 are located between the egg 4 transported by the carrier 3 and the feeding device 10,
It is pivoted on the machine frame in parallel with the carrier 3 and is rotated in the same direction as the carrier by a monitor.

The lower end of the scraper 13 is in sliding contact with the upper part of the rotating brush 14, and on the lower surface of this rotating brush 14, the upper surface of the egg 4, which is held in the fitting part of the carrier 3 together with the rotating brush 15 and forcibly rotated in a counterclockwise direction, is slid. Rotate while touching. Double rotating brush 1
A transfer roller 16 that rotates while slidingly contacting between the transfer rollers 4 and 15 is pivotally supported on the machine frame in parallel with the carrier 3. An appropriate amount of coating liquid supplied from the supply device 10 is transferred to the transfer roller 16 via the scraper 13 and then transferred to the two rotating brushes 14 and 15.
may be supplied to

The surfaces of the supply drum 12 and the transfer roller 16 may be made of metal, rubber, or synthetic resin such as vinyl chloride, as long as they have low frictional resistance and hardly absorb the coating liquid. The brush material of the rotating brushes 14 and 15 may be appropriately selected in terms of hardness, material, and shape depending on the type of coating liquid or the type of agricultural products, but synthetic resin materials are preferable.

The operation of the coating apparatus of the present invention constructed as described above will be explained. The endless chain 2 is driven in the direction of the arrow, and the egg 4 to be coated is inserted into the insertion part of the carrier 3 which is pivotally supported by the endless chain 2. When the egg 4 is transferred onto the belt 6, the belt 6 is driven in the direction of the arrow by the drive drum 7, and the carrier 3 in contact with the belt 6 is rotated, so that the egg is transferred onto the belt 6. 4 is forced to rotate. At the same time, the egg 4 is forcibly rotated and is sequentially transferred in the direction of the arrow, that is, in the direction of movement, while slidingly contacting the lower surfaces of the rotating brushes 14 and 15. During this time, the coating liquid is supplied to the rotating brush 14 in appropriate amounts via the coating liquid supply device 10.
This coating liquid is quickly applied to the surface of the egg 4 that is in sliding contact with the lower surface of the rotating brush 14 without drying. Coating liquid supply device 10
The coating liquid supplied to the rotating brush 14 is simultaneously transferred to the transfer roller 16, and the coating liquid adhering to the surface of the transfer roller 16 is transferred to the other rotating brush 15, where it is rubbed on the lower surface of the rotating brush 15. It is applied to the surface of the egg 4 that is in contact with it. The rotating brush 14 to which the coating liquid is directly supplied from the supply device 10 has a larger amount of coating liquid attached to it than the rotating brush 15 to which the coating liquid is indirectly supplied via the transfer roller 16. Then, the coating liquid is applied to the surface of the chicken egg 4, and even if there is a coating leakage, the coating liquid is applied by the next rotating brush 15, and is spread and coated evenly and evenly. The coating liquid is applied to the surface of the chicken egg 4 by the rotating brushes 14 and 15, but both rotating brushes 14,
Since the egg 4 on the carrier 3 is forcibly rotated on the lower surface of the carrier 3 as described above, the surface of the egg 4 is slid into contact with the rotating brushes 14 and 15 multiple times, so that it can be removed in an extremely short period of time. A desired coating film is formed on the surface of the egg 4 during the transport distance. In this way, since a film of coating liquid is efficiently formed on the surface of the chicken egg 4 by both rotating brushes 14 and 15, it goes without saying that only one rotating brush 1
The intended purpose can be sufficiently achieved by using only 4.

As described above, the device of the present invention supplies a small amount of the appropriate coating liquid using the supply device that is finely adjusted by the rotation of the supply drum, and rotates the coating liquid so that it comes into sliding contact with the upper surface of the egg being transported by the carrier. The egg is transferred to a rotary brush, and the belt is in sliding contact with the lower surface of the carrier that transfers the eggs, and the carrier is forcibly rotated, so that the eggs can be forcibly rotated.
A minute amount of coating liquid of 0.1 to 0.2 grams can be applied evenly and uniformly to the surface of chicken eggs in a short period of time and over a short transfer distance, and simple components are organically bonded to make it cheap and easy. can be produced.

The coating device for agricultural products of the present invention includes agricultural products that are forcibly rotated via a carrier by a forced rotation device, and a rotating brush that continuously receives an appropriate amount of coating liquid transferred from a coating supply device onto the surface of the agricultural products. By sliding into contact with each other at high speed, a uniform coating film with no unevenness of the coating liquid is formed, so the time and distance required for forming the coating film can be significantly shortened. . Therefore, this coating device can be easily installed in the middle of general-purpose cleaning equipment.
Normal cleaning operations can be continued without adversely affecting the cleaning device. In addition, each component of the device of the present invention is extremely simple, so there is no possibility of failure, and the time and effort required for preparation before and after work and cleanup can be greatly reduced, and maintenance management is also easy. It has many characteristics such as, and has extremely great industrial value.
