Abstract

To provide a device for efficiently separating a calyx from a fruit.SOLUTION: In a device for efficiently separating a calyx from a fruit by making use of a characteristic that the calyx is relatively harder than the fruit, red pepper conveyed by the respective rollers is hindered on the way from passing through an aperture 8a-8b due to a relatively hard and large calyx; in this respect, rollers 10a-10b and rollers 11a-11b pull a fruit 1a with an angle formed between the rollers and the calyx 1b, and therefore a breaking force is generated at a boundary face between the fruit 1a and the calyx 1b to cause cracking, so that the calyx 1b is separated from the fruit 1a; the separated fruit is discharged to an outside of the mechanism as it is by the rollers 10a-10b and the rollers 11a-11b; and the calyx remains in a state of being interposed between the aperture 8a-8b.SELECTED DRAWING: Figure 9

Description

The present invention relates to a method for easily separating fruit and spatula in a plant body.

Some vegetables need to be separated from the spatula in order to use the fruits after harvesting. This separation work is often manual. As a background of the present technology, the case of chili with stickers will be described as an example.
Chili is used as a spice in a wide range of fields. Raw peppers are used as cooking ingredients, seasonings, and pickles, and dried peppers are used as cooking spices and coloring agents, and because of their irritation, they are fungicides, food and vegetable repellents, and repellents that cause damage It is also used. In order to use these chili peppers industrially, it is necessary to separate the fruit part from the sticky part. Although there are attempts to mechanize this separation process, the shape of fruit and shape of the fruit are various, and it has not reached practical development. Therefore, the current situation is that it relies on manual work, and there is a need for efficient work in the chili industry.

Manual separation of fruit and crush is very inefficient.
Although the technology for separating fruit and spatula using plant hormones or ethylene gas has been studied, it has not been put into practical use. Therefore, the problem to be solved by the present invention is to provide a method for efficiently separating fruits and stickers.

When trying to remove (separate) using the present invention, for example, chili peppers are relatively soft and easily deformed against external forces such as pressing, even in the raw state immediately after harvesting or after drying. Hard and difficult to deform. The difference between the deformability is used to separate the fruit and the crush.

By carrying out the present invention mechanically and continuously, the fruit and the spatter can be easily separated in a short time. Compared with conventional manual separation, the working efficiency can be significantly increased. Moreover, the fruit appearance is equivalent to that during manual work, and can be used for various processed products without discrimination.

The case where this invention is utilized for the chili which is a fruit with a sticky is demonstrated with reference to an accompanying drawing.

Fig. 1 shows the names of the pepper fruit parts.

FIG. 2 is an operation diagram of a finger when the chili pepper is removed manually. Separation of 1a fruits and 1b heads requires considerable force in four directions of linear pulling. If you try to pull away with excessive force, the fruit may be cut. By applying a force in five directions to break the fruit and crush, the boundary surface between the fruit and cough tears as shown in 6 of FIG. 3 and can be easily separated.

FIG. 4 is a conceptual diagram of a mechanism for separating chili fruits and crumbs. It has a pair of rotating rollers 7a-7b that draws the chili with sticker 1 and conveys it while deforming the fruit by pressing in order to make it easy to enter between the gaps 8a-8b separating the sticker and the fruit. The 7a roller has a driven spring 12 to give a proper pressure to the pepper. 8a-8b is a structure having a gap that allows the fruit deformed by the pressure to pass through and prevents the passage of the plastic that is difficult to be deformed by the pressure. Rollers that pull the pepper fruit that has passed through this gap structure are 10a-10b and 11a-11b. These 10a and 11a rollers also have springs 13 and 14 that are driven to obtain an appropriate friction for pulling without breaking the fruit. Reference numerals 9a and 9b are guide blades for guiding bent chili so as not to be wound around the 7a-7b roller. These 10a-10b and 11a-11b are arranged with a fixed angle of 15 with respect to the insertion conveyance system. Pepper insertion into the mechanism of the present invention is always established by putting the fruit part 1a side first. A mechanism for systematizing the present invention and putting the fruit part 1a first will be described with reference to FIG.

FIG. 5 is a conceptual diagram of a drive system that rotates a roller system that conveys chili. A chain 20 is connected between the motor of the power source of 18 and the sprockets 19a to 19h fixed to each roller shaft. The effective pitch diameters of the 7a-7b roller and the 10a-10b, 11a-11b sprockets are optimized so that the pepper feed rate is the same. Since the rollers of 7a, 10a, and 11a move up and down in the directions of 21a to 21c when the chili passes, a chain tension mechanism for moving the sprocket of 19b in 22 directions by the spring of 23 is arranged.

6, FIG. 7, FIG. 8, FIG. 9, and FIG. Description of FIG. Pepper fruit 1a is put between 7a-7b rollers before seta 1b. Here, the fruit of 1a is pressed and pressed against the fruit by 12 springs so that the fruit of 1a can easily enter the gap of 8a-8b. The spring force of 12 is set to a force that does not deform the fruit and deforms the fruit. The fruit tip is pushed into the gap structure 8a-8b by the guide blade 9a-9b.

Description of FIG. The tip of the fruit part that has passed 8a-8b is taken over from the 7a-7b pushing roller to the pulling roller 10a-10b, and the pepper fruit continues to be transported in the mechanism.

Explanation of FIG. The chili pepper conveyed by each roller is prevented from passing by a gap between 8a and 8b, which is relatively hard and large on the way. Here, since the rollers 10a-10b and 11a-11b pull the fruit of 1a at an angle with respect to the 1b head, a force for breaking on the same principle as the five directions in FIG. 2 is generated at the interface of the 1a fruit-1b head However, as shown in 6 of FIG. 3, a crack occurs and 1a fruit and 1b head are separated.

Description of FIG. The separated fruit is discharged out of the mechanism as it is by 10a-10b and 11a-11b rollers. Heta remains sandwiched between 8a-8b.

Description of FIG. It is a conceptual diagram of the mechanism which pushes out the remaining 1b while being sandwiched between 8a-8b in the mechanism. When 24 squeezing pieces are pushed in 26 directions by 25 cylinders, they are discharged out of the apparatus in 27 directions along 8a-8b. Moreover, depending on the dry state and surface friction state of the chili pepper, the 1a fruit may not be drawn by the 10a-10b and 11a-11b rollers, and the fruit may slide on the roller and remain in the mechanism without separation of the fruit and the sticker. . Also in this case, when the setter is pushed by 24 settling pieces, the boundary between the fruit and the sett shown in 6 of FIG. 3 is cracked and easily separated. After the separation, the material is taken out of the apparatus as it is with 24 frames. This mechanism is a part according to claim 5.

FIG. 11 shows an embodiment in which the counter unit is systematized. The pepper with the sticky of FIG. 1 is thrown into 31 hoppers. The introduced chili is appropriately dropped onto 30 holders on 29 conveyors by rotating 32 rollers with 33 motors. The 30 chili holders are intermittently fed by 28 motors, which are repeatedly conveyed and stopped. Reference numeral 34 denotes a hue sensor. A relatively red or yellow fruit part and a relatively green part can be distinguished by a hue sensor. When the 34 hue sensors are scanned over the pepper with 36 cylinders along the 35 guides, the color of the fruit is confirmed after the color of the texture, or the color of the texture is confirmed after the color of the fruit. It is possible to determine which direction the sticky fruit is facing on the holder. The fruit separating apparatus of the present invention must ensure that the fruit enters the roller before the material. Therefore, the chili pepper on the holder in the direction in which the flute comes first with respect to the 43 fluttering unit is turned 180 degrees in the direction of 47 using the 38 chili chuck, 39 rotations, and a straight cylinder. As a result, the direction of fruit and sticker becomes constant, and 41 cylinders are pushed into the 43 sticker removing unit of the present invention at the next conveyor stop position. The separated fruits are dropped and collected in 44 boxes, and the heta is dropped and collected in 45 boxes. In addition, when the hue sensor cannot clearly determine the fruit and the sticker, it is not pushed into the sticker removing mechanism of the present invention but is directly conveyed by the conveyor and dropped into the 46 collection box.
