Description

[Detailed Description of the Invention] 5. The present invention is applicable to odoroids such as eggs, apples, peaches, and pears;
The present invention relates to a rotary ink method and apparatus for spherical and similar shaped agricultural products.

The object of the present invention is to provide a novel coating method and apparatus that can form a uniform coating film on the entire circumferential surface of these agricultural products from the beginning of the work. Conventionally, this type of coating method and its equipment, taking the case of eggs as an example, require only a small amount of coating liquid of O, 12 CC per egg. This inevitably leads to overdosing, which is uneconomical, and it is technically difficult to uniformly coat a very small amount due to the fact that the object to be coated is a natural product and its shape is irregular. difficult.

Therefore, for example, a pressurized metering pump that operates the coating liquid intermittently is used to transfer the coating liquid to gauze, etc., which is placed on a saucer with multiple rows of slits at the bottom of a pipe with many small holes drilled around the pipe. A coating method was attempted in which the wet coating liquid was dropped and spread on a plan roller placed below the slit and rotated by a drive source as appropriate, but before the work started. In addition to requiring a lot of effort and time for preparation, cleaning after work, and assembly, uneven coating may occur on agricultural products supplied immediately after the start of work (3F). The method of spraying by reciprocating a spray gun has disadvantages such as a large loss of coating liquid and being uneconomical. 35 The present invention was finally completed as a result of intensive research in view of the above-mentioned conventional defects, and will be explained below with reference to the drawings.

A guide rail 13 is installed in parallel to the conveyance compare 1, and its upper surface is preferably formed with small grooves in an uneven shape.

Reference numeral 10 denotes a support portion that is rotatable between conveyor chains 1a, 1a in parallel with an interval that allows agricultural products 4 to be straddled and held between carriers 3, which will be described later, in a direction perpendicular to the direction of movement of the conveyor. A plurality of rows of carriers 3 each having a plurality of collar pieces 2 arranged in a concave shape are fitted to the loosely fitted shaft rod 14, and sprockets 15, 15 are fixed to the shaft rod 14 on both sides thereof. has been done.

Reference numeral 11 denotes an endless chain which is rotated counterclockwise by an appropriate driving source, and reference numeral 9 denotes a brush roller having a plurality of rows of flexible brushes planted at regular intervals around the endless chain.

12 is a coating liquid supply device.

6 is a pan arranged in an inclined manner at the bottom of the device 12;
A plurality of brushes 8 made of fimbriae are secured to the lower end of the pan 6 in a plurality of rows corresponding to the areas where the agricultural products are transferred, and a spongy body 7 is laid on the upper part of the brush 8.

The corpus cavernosum 7 prevents the coating liquid 5 flowing on the pan 6 from directly dripping from the lower end of the pan 6, and at the same time, uses the surface tension of the liquid to accumulate the fluid and form a brush consisting of a group of fimbriae. It exists in order to continuously supply a fixed amount of liquid to 8 by capillary action. Therefore, the corpus cavernosum 7 referred to in the present invention refers to a material that exhibits the above-mentioned functions, and includes, for example, sponge, sponge rubber, woven fabric, nonwoven fabric, and cotton. Next, the operation of the present invention will be explained with reference to FIGS. 1 and 2. In conjunction with the activation of the motor 1 (not shown), the endless chain 11 rotates counterclockwise, and the conveyor 1 rotates in the direction of the arrow. to move to.

Due to this transition, the shaft rod 14 loosely fitted between the conveyor chains 1a, 1a is connected to the sprocket 15 fixed to the shaft rod 14.
, 15 move on the guide rails 13, 13, their lower surfaces contact the guide rails 13, 13, so the carrier 3 itself rotates counterclockwise (in the direction of the arrow), and the carriers 3 that are adjacent to each other rotate. , 3, the produce A is rotated clockwise due to friction and transferred as the transfer conveyor 1 moves. During this time, the coating liquid supply device 1 is controlled by manual or mechanical control means.
Appropriate amounts of the coating liquid 5 are supplied onto the bun 6 via the device 12. However, since the pan 6 is tilted and the corpus cavernosum 7 is laid at the end of the erection plate, the coating liquid 5 is supplied from the device 12 to the top of the bun 6. Even if an excessive or small amount of coating liquid is supplied irregularly onto the bun 6, the corpus cavernosum 7 absorbs and retains the liquid, and in order to adjust the variation in the amount of coating liquid supplied, it slides into contact with the brush roller 9 and is consumed. Coating liquid 5
is a brush 8 consisting of as many fimbriae groups as necessary due to capillary action.
The brush roller 9 is immediately spread and coated on a flexible brush roller 9 which is rotated and transferred via the brush 8, and the brush roller 9 is in sliding contact with the surface of the agricultural products 4 which is transferred while rotating. Since it rotates counterclockwise in the same direction as the rotation direction of the machine, it smoothly forms a uniform coating film on the surface of agricultural products without any spots. As described in detail above, the method of the present invention allows the coating liquid to be uniformly diffused and distributed to the rotatable brush roller 9 at the end that comes into direct contact with the produce almost immediately after startup, so that the coating liquid is evenly distributed from the beginning of the work. It can be coated, and the preparation before and after work and the work after work can be significantly shortened, improving work efficiency and contributing to cost reduction.

In addition, the device of the present invention organically combines elements with a simple structure, requiring only a low cost for equipment, and can be easily manufactured. Agricultural products with a completely uniform coating film are sent out one after another from the conveyor exit, and it can be easily installed in the middle of a general-purpose washing system line, extending the capacity of existing washing machines. Since the operation of each component is very simple, there is no risk of equipment failure and maintenance is easy, so it has great industrial value.
