Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to sprouts, shredded vegetables, and other elongated products (these are collectively referred to as "sprouts" in the present invention).
The present invention relates to an apparatus for dividing and supplying a fixed amount for the purpose of bagging a fixed amount at a time. (Prior art) There is already a device that transports sprouts to a weighing bucket for measuring a predetermined weight by a scraping conveyor and discharges the sprouts in the weighing bucket when the weight reaches a predetermined value (Japanese Patent Application No. 59-170930), and a device designed to receive sprouts dropped from a scraping conveyor into a weighing bucket, loosen them, and disperse them into the weighing bucket has already been proposed. (Japanese Patent Application No. 61-2897074). In these conventional devices, depending on the goods to be conveyed,
In some cases, the loosening operation was not sufficient. (Problems to be Solved by the Present Invention) The present invention provides a fixed-quantity supply device that enables more accurate and fixed-quantity take-out of articles that are likely to be entangled with each other and difficult to uniformly transport. Is what you do. (Means for Solving the Problems) According to the present invention, an upper end portion of a scraping conveyer having a conveyor belt provided with a large number of needle-like bodies and disposed at an angle from a lower bean sprouts reservoir. And a loosening device in which a large number of needle-like bodies are arranged and rotated in a direction opposite to the scraping conveyor. (Operation) According to the above configuration, even if sprouts discharged from the upper end discharge portion of the scraping conveyor are mixed with sprouts, the needle-shaped body of the scraping conveyor and the loosening device arranged opposite to each other. Is once received in the valley formed between the needles, and is gradually loosened by a number of displaced needles of the loosening device and dropped into a quantity bucket in a dispersed state. Therefore, the supply of sprouts to the weighing bucket is uniform and smooth, and the weighing is performed accurately, so that accurate quantification can be taken out. (Examples) Hereinafter, the present invention will be specifically described based on the illustrated examples. In FIG. 1, reference numeral 1 denotes a scraping conveyer arranged upright from a sprouts reservoir (not shown).
As illustrated at the upper end thereof, an endless transport belt 3 having a large number of needles 2 implanted therein is provided. Numeral 4 denotes a sprocket, and two endless chains 5 are stretched between the sprocket 4 and another sprocket not shown as shown in FIGS. 2 and 3, and the two endless chains. The conveyor belt 3 described above is constituted by a large number of conveyor plates 6 having a large number of needle-like bodies 2 implanted thereon and being mounted horizontally. Opposite to and slightly below the sprocket 4, a drum 8 having a large number of needles 7 implanted on the same surface is disposed rotatably. The drum 8 is received and fixed in an elongated slit in the up-down direction, as shown by 9 in FIG. The drum 8 on which a large number of needles 7 are implanted constitutes the loosening device according to the present invention. The drum 8 is rotated in the direction of the arrow opposite to the sprocket 4 at the upper end of the conveyor 1. Although the peripheral speed of the conveyor belt 3 of the scraping conveyor 1 and the peripheral speed of the drum 8 are the same, the rotational drive of the drum 8 is taken from the power system of the conveyor belt 3,
Alternatively, another independent driving device may be employed, but the driving of both is synchronized. An endless belt 10 is stretched between pulleys 11 and 12 below the upper end discharge portion of the scraping conveyor 1 and is moved in the direction of the arrow in the same direction as the upper end discharge portion of the conveyor belt 3. Reference numeral 13 denotes a driving motor. The rotation of the motor 13 drives and rotates the drum 8 via a gear 14 and a belt 15 and rotates the belt.
The endless belt 10 is driven via 16,17. Reference numeral 18 denotes a hopper, and a weighing bucket is provided below the hopper 18.
19 are arranged. Between the hopper 18 and the weighing bucket 19, there is provided a shutter 20 for blocking a fall passage between the two. In the above-described apparatus, the sprouts to be supplied in a fixed amount are carried from a reservoir (not shown) while being held by the needle-shaped body 2 of the conveyor belt 3 constituting the conveyor 1 and dropped from the upper discharge end thereof. . At this time, the sprouts are not always uniformly dispersed and conveyed on the scraping conveyor 1, but are discharged from the conveyor belt 3 because the drum 8 on which the needles 7 are implanted is rotated at the discharge end thereof. Even if the sprouts were intertwined in a lump state,
It is once received in the valley between the conveyor belt 3 and the drum 8 and loosened by the needles 7 of the drum 8 and gradually disperses by tearing left and right with both needles rotated in opposite directions. So that they fall uniformly. The two needles 2 and 7 are arranged so that the tips are slightly inserted into each other as shown in the figure, but the amount of the needles together with the length of the needles and the like depends on the article to be conveyed. An appropriate value may be selected accordingly. At the upper end of the conveyor belt 3, a part of the sprouts conveyed is attached to the needle-like body 2 and is brought to the left in FIG. Sprouts are transported in the original direction by an endless belt 10 disposed below. These sprouts are dispersed in a scattered manner and fall into the measuring bucket 19 via the hopper 18. In order to quickly measure and extract the sprouts by a constant weight, the scraping conveyor 1 is first transported at a high speed, and first the sprouts are transported in large quantities. When the weighing bucket 19 measures a predetermined weight smaller than the predetermined amount to be weighed, the scraping conveyor 1 is slowed down, and the sprouts are conveyed little by little, and the weighing bucket is transported.
Drop small amounts of sprouts to 19. When a predetermined amount to be weighed is measured by the weighing bucket 19, the shutter 20 is operated, and the hopper 18 and the bucket 19 are operated.
19, which blocks the falling path between
The driving of the scraping-up conveyor 1 is stopped while keeping it from entering the inside. In this way, the predetermined weight of the articles received in the weighing bucket 19 is discharged, and the next weighing operation is repeated. As described above, the driving of the drum 8 and the endless belt 10 constituting the unraveling device is driven by a common driving source or a separate driving source in synchronization with the speed and the start / stop operation of the transport belt 3. In the embodiment described above, the drum 8 in which the needle-shaped member 7 is implanted on the circumference is shown as a loosening device, but the needle-shaped member 23 is located between the two rollers 21 and 22 as shown in FIG. For example, the endless belt 24 attached may be used. Further, in the above-described embodiment, a description has been given of an example in which the scraping conveyor is moved from high speed to low speed for measurement and stops when the weight reaches a predetermined weight, but the scraping conveyor is always driven at a constant speed. Alternatively, it is not necessary to stop at every metering, and may be changed as appropriate in designing the quantitative supply device. (Effect) In the present invention, since there is provided a loosening device in which a large number of needle-like bodies which are disposed to be displaced and are displaced to face the upper end discharge portion of the scraping conveyor are discharged from the scraping conveyor. The sprouts lumps are once received by the needle-shaped body of the loosening device, loosened gradually, adhered to the needle-shaped body partially, transported a little, and dropped to make a weighing bucket in a dispersed state. Is put into. Therefore, it is possible to reliably prevent the agglomeration from falling down in a lump, so that the quantitative point can be accurately detected and the quantitative extraction can be accurately performed.
