Description

DETAILED DESCRIPTION OF THE INVENTION The present invention automatically and continuously moves a large number of water-sedimentable and easily deformable articles one by one onto a processing belt conveyor at an appropriate distance for various processing. The present invention relates to an automatic feeding device that can feed objects separately.

More specifically, an aggregate of water-sedimentable amorphous objects such as raw shelled oysters, octopus, shrimp, etc. (hereinafter referred to as ``raw oysters, etc.'') is taken out of the water, and each piece is separated at appropriate intervals. This invention relates to an automatic feeding device that is capable of automatically and continuously feeding materials onto a processing belt conveyor to facilitate post-processing.

Conventionally, in the case of individual separation processing of raw oysters, such as individual separation quick freezing processing, automatic feeding to the processing process has been extremely difficult due to the ease of deformation or the difficulty in separating them individually. A commonly used freezing method has been to manually arrange raw oysters, etc. on pre-sterilized trays at appropriate intervals, and then feed the trays into a freezer using a processing belt conveyor. Since this method requires human labor, it was expected that an automatic separate and feed device for raw oysters, etc., would emerge.

The reasons why raw oysters are difficult to handle automatically and continuously are: 1) They are extremely soft and easily deformed, 2) Their size varies depending on the degree of growth, and 3) Their mechanical strength is low. They are extremely small, and the surface is easily damaged.Therefore, a general mechanical alignment method has been applied, and a method that relies on human power has had to be adopted.Individual quick freezing This is because the important issues are not overlapping individual products and improving freezing efficiency.In other words, if the supply to the freezing equipment is extremely low, the operating rate of the freezing equipment will decrease; In case,
Since multiple raw oysters, etc. are frozen while being in contact with each other, it becomes difficult to handle the frozen products after weighing, packaging, etc., and also reduces the product price. Furthermore, it is almost impossible to separate raw oysters or the like from each other when they are frozen in a frozen state without damaging them. As a result of intensive research on these points, the present inventors have developed an automatic feeding device for raw oysters, which have been considered the most difficult and neglected, onto a belt conveyor, especially for individual separation and quick freezing. He succeeded in perfecting an automatic feeding system, which made it possible to save a lot of labor and time, and also to improve productivity.

The device of the present invention basically consists of a water tank filled with water that acts as a lubricant to make it easier to separate raw oysters, etc. into individual pieces and to prevent them from being damaged; A hopper that continuously supplies raw oysters, etc. to prevent them from settling and accumulating at the bottom of the aquarium and being unable to be scooped out} A variable-capacity basket or finned belt conveyor that scoops up raw oysters, etc. one by one, and this It consists of a driving device.

The material constituting the device according to the present invention is not particularly limited, considering that it is mainly used for food and can be combined with an aquarium, as long as it is not a material that extracts or generates toxic substances or a material that causes rust.

An example of the device according to the present invention will be explained using FIGS. 1 to 7.

Figure 1 shows pulleys 3a, 3b, 3 that can drive a belt conveyor 2 in which baskets or fins 1 are arranged in a staggered manner.
c, on the surface for scooping up oysters, etc. 4, there is a feeding part 5 for oysters, etc., which has a large volume and is scooped into a basket or fins, and a lower part, where the oysters, etc. have the ability to settle in water;
To prevent this, the tubular portion 6 is placed as close as possible to the basket or the like so that it does not slip over the basket or fins without being scooped up by the basket, etc. The hoppers 5 and 6 are installed in a water tank 7 so that the basket or fin of the part that scoops the oysters, etc. 4 is at least submerged in water, while the belt conveyor that scoops the oysters, etc. 4 is moved. A belt conveyor 8 is placed directly below the pulley 3c, which is reversed, to transport and feed the oysters 4 one by one into the secondary processing process. In addition, pool
The driving mechanisms for the Lees 3a, 3b, and 3c may be any conventional means and their explanation will be omitted.

Figures 2 to 4 are partially cutaway views of an example of a belt conveyor with a basket, which is a part of the structure of the present invention, and Figure 2 is a plan view thereof. It consists of a bottom part with holes h, and on the belt conveyor 2,
The entrance portion is arranged facing forward in the direction of movement of the belt conveyor. The arrangement of the baskets 1 on the belt conveyor 2 is such that when the oysters, etc. are transferred to the belt conveyor 8 for secondary processing, they do not overlap each other, and the intervals are such that the intervals are not too large and reduce the efficiency of freezing, etc. Moreover, they are arranged in a staggered manner to prevent them from slipping between the baskets and settling downward in the water tank 7. As for the degree of growth, as described above, the capacity of the basket and the interval between the baskets may be appropriately selected depending on the growth level of the oysters, etc., and the belt conveyor may be connected to a conventional means. It is preferable that the entrance of the basket be wide.

If the drainage holes at the bottom are too large, raw oysters and the like will easily get eaten up and become an obstacle when transferring to the processing belt conveyor 8. Therefore, it is preferable not to make them too large, and rather to increase the number of holes. It is convenient for post-processing to be able to drain the water sufficiently. FIG. 3 is a cross-sectional view taken along the line mm in FIG. 2, where 1 is a basket, d is its entrance, h is a hole provided in the bottom, and 2 is a belt conveyor.

FIG. 4 is a sectional view taken along the line W-W in FIG. 2, and the drawer display characters are the same as in FIG. 3.

FIG. 5 is a partially cutaway view of an example of a finned belt, which is arranged in a staggered manner as in the case of a basket.

Reference numeral 1 denotes a fin having a partition part 3, the height of which can be appropriately selected and changed depending on the size of the product such as raw oysters, to the extent that two or more oysters are not piled up. The attachment to the belt conveyor 2 is the same as in the case of the basket described above.
Conventional methods are sufficient. The height of the partition 3 should be selected to be the same as the height of the fins, but when the raw oysters etc. scooped up by the fins are transferred onto the belt conveyor 8, they do not overlap each other, and the intervals are too wide, resulting in secondary processing. In this case, it is necessary to select the middle (the middle direction of the belt conveyor 2) so as not to reduce the efficiency of freezing processing. Figure 6 represents a cross-sectional view of - in Figure 5, the drawer display characters are the same as those in Figure 5, Figure 7 represents a skin-to-skin cross-sectional view of Figure 5, and h is the bottom of the fin. The other drawer display characters are the same as those in FIG. 5.

The two examples described above do not restrict the configuration of the present invention.

That is, the present invention provides (i) a plurality of pulleys disposed inside and outside the aquarium and their driving parts; Baskets or fins 9 arranged in a shape and having a variable capacity for individually scooping up water-sedimentable and easily deformable items.
At the position where the belt conveyor emerges above the water surface when it is driven, the upper part is a replenishment part with a large capacity for water-sedimentable and easily deformable articles, and the lower part is a replenishment part with a large capacity for items that are easily deformed by water, and the lower part is a replenishment part that is placed in a basket or fins on the belt conveyor as much as possible. A water-sedimentable and easily deformable individual automatic feeding device is characterized in that it is constituted by a hopper consisting of closely surrounding tubular portions.

The effects of using the device of the present invention will be shown below by way of examples.
