Description

[Detailed description of the invention] The present invention relates to a transfer device for an automatic sorting machine.

For example, in a known fish sorting device, fish transported by a supply conveyor are transferred to a sorting and sorting conveyor that is perpendicular to the bottom of the feed conveyor, and the sorting and sorting conveyor uses a computer to sort fish by pattern recognition using a computer. ing.

In order to transfer the fish from the supply conveyor to the sorting and sorting conveyor, it is necessary to arrange the fish one by one in the center of the sorting conveyor pan that is running continuously, and the transfer must be done manually by the worker. However, because fish vary widely in shape, size, and weight, and because fish are slippery, manual transfer of large quantities of fish is time-consuming, inefficient, and inefficient. It is both sanitary and dangerous, and in particular, manual transfer is extremely difficult due to recent improvements in fish sorting capabilities, such as a decrease in the effective width of the sorting pan, an increase in sorting travel speed, and a reduction in processing time. It is becoming.

The present invention was proposed in view of the above circumstances, and an object of the present invention is to provide a safe, highly efficient, and sanitary transfer device for automatic sorting machines.

To this end, the present invention provides a transfer device for an automatic sorting machine that transfers a plurality of objects to be sorted simultaneously fed from a feed chute onto a sorting and discharging pan that continuously runs below the feed chute. A transfer bucket is provided with a plurality of hoppers arranged in tandem at equal intervals and a slide gate for opening and closing the lower end openings of the hoppers all at once; A transfer conveyor having hoppers arranged in tandem at the same interval and a slide gate that opens and closes the lower end openings of the hoppers all at once, and the transfer conveyor is placed at an upper position directly below the transfer bucket and at a lower position directly above the sorting and discharging pan. a moving mechanism that moves cyclically in a vertical vertical plane between the hoppers of the transfer conveyor; It is characterized by comprising a plurality of sorting and dispensing pans.

An embodiment in which the present invention is applied to the transfer of fish in a fish sorting device will be explained with reference to the drawings. Figs. 1 and 2 are longitudinal sectional views thereof, and Fig. 1 shows a state in which the transfer conveyor runs in the upper position. FIG. 2 shows the state in which the transfer conveyor runs in the lower position. FIG. 3 is a sectional view taken along the line - in FIG. 1.

In the above figure, 1 is a transfer bucket made up of five hoppers arranged in tandem at an equal pitch P, 2A is a bucket slide gate that passes vertically through the lower part of the transfer bucket 1 and opens and closes the lower end openings of the five hoppers all at once, 3 1 is a transfer conveyor extending vertically along the transfer bucket 1, and the front and rear endless transfer conveyor chains 5, 5 extend in the longitudinal direction, and the front and rear ends thereof are provided with free rotation bearing portions 4, 4, respectively. It has five hoppers that are pivotally mounted and vertically arranged at the same pitch P as the hoppers of the transfer bucket 1, and a conveyor slide gate 2B that opens and closes the lower end opening of each hopper at the same time. Reference numeral 6 denotes a pair of front and rear conveyor drive sprockets, each of which has both ends of the front and rear transfer conveyor moving chains 5 wrapped around each other at a distance 1.
7 is a conveyor synchronous drive sprocket coaxially fitted to each of the front and rear conveyor drive sprockets 6, 6 for driving the transfer conveyor moving chain 5 in synchronization with a conveyor drive chain 8 to be described later; It rotates in mesh with the delivery bread travel chain 9, and drives the front and rear conveyor movement chains 5 at the same traveling speed in synchronization with the sorting delivery bread travel chain 9 via the conveyor drive chain 8 and the synchronous drive sprocket 6A. The sorting and dispensing pan synchronization sprocket 10 to be driven is a plurality of sorting and dispensing pans vertically installed in a sorting and dispensing pan travel chain 9, and the sorting and dispensing pans are arranged in tandem at the same pitch P as the hopper interval of the bucket cart 1. 11A and 11B are brackets 12A and 12B respectively
A hydraulic cylinder attached to the transfer bucket cart 1 for opening and closing the bucket slide gate 2A of the transfer bucket conveyor 3 and the conveyor slide gate 2B of the transfer conveyor 3; 13 a bearing for pivotally supporting the transmission shaft 14 of the sprocket 6 protruding from the machine frame; Reference numerals 15 and 16 are an upper rail and a lower rail, respectively, which are fixed to the machine frame side and extend in the longitudinal direction; 17 is a transfer part frame which is fixed to the machine frame side and fixes the transfer bucket 1; and 18 is an upper part of each bracket of the transfer bracket 1. A supply chute is installed laterally in each of the two.

In such a device, transfer bucket 1
Each of the hoppers has a wide receiving width at the upper end opening and is narrowed from the center to the lower end opening according to the effective width of the fish body, and the bucket toss slide gate 2A is energized by the hydraulic cylinder 11A to receive the fish.
It is opened and closed at the timing of the waiting period and transfer, and the difference in the supply and falling time of each type of fish is absorbed by the timing of opening and closing of the bucket toss slide gate 2A, and each hopper of the transfer bucket 1 is connected to the corresponding hopper of the transfer conveyor 3. When the fish are directly below it, they open all at once, and the five fish are simultaneously supplied from each hopper of the transfer bucket 1 to each hopper of the transfer conveyor 3, and are fed to the hydraulic cylinder 11A.
returns and the bucket slide gate 2A closes.
The bucket slide gate 2A remains closed until the next opening.

Like each hopper of the transfer bucket 1, each hopper of the transfer conveyor 3 has a wide receiving width, and is narrowed from the center to the bottom opening to match the effective width of the fish, and the hopper spacing is the same as the hopper spacing P of the transfer bucket 1. It is.

The transfer conveyor 3 is attached to front and rear conveyor moving chains 5, 5 by free rotation bearings 4 at four locations on the front, rear, left, and right, respectively, and the front and rear conveyor moving chains 5, 5 are respectively attached to sorting and dispensing bread traveling chains. Since the transfer conveyor 3 moves along an oval trajectory with a horizontal movement distance l in the vertical vertical plane at the same traveling speed as the conveyor 9, the transfer conveyor 3 also follows the same oval and when traveling in the upper position, the sorting and dispensing pan 10
When traveling in the lower position, it travels in the same direction as the traveling direction of the sorting and dispensing pan 10 at the same traveling speed.

At this time, the conveyor moving chains 5, 5 move along the upper rail 15 when traveling in the upper position, and along the lower rail 16 when traveling in the lower position, so that the transfer conveyor 3 causes vibrations in parallel and vertical movements. The transfer is carried out smoothly and lightly, and the gap between the transfer bucket and the sorting and dispensing pan 10 is maintained.
Maintain a constant gap between each.

In this way, as shown in FIG.
When the transfer bucket 1 coincides with the position of the five hoppers, the transfer bucket 1 supplies the oil, and as shown in FIG. Through the conveyor slide gate 2B which is opened by the actuation, five fish are reliably arranged and transferred to the central part on the sorting and discharging pan 10 at the same time during the movement of the transfer conveyor 3 over a traveling distance l.

After the synchronous movement distance l, the transfer conveyor 3 rises to the upper position along the outer periphery of the conveyor drive sprocket 6, the hydraulic cylinder 11B returns to its original position, and the conveyor slide gate 2B fully closes before moving to the upper position. Then repeat this exercise.

Meanwhile, transfer conveyor 3 also has 5 per row on one side.
Since it has two hoppers, five fish are supplied to the sorting and dispensing pan 10 each time the conveyor slide gate 2B is opened and closed, and when the transfer conveyor 3 goes around once, it is synchronized with the next new sorting and dispensing pan 10, and the same Fish can be constantly supplied to the sorting and dispensing pan 10 according to the specified schedule, and the operation is synchronous to avoid empty sorting and dispensing pans, so that the transfer efficiency is improved.

In addition to seafood, this device can also be applied to the transfer of vegetables, fruits, etc. for size separation.
