Abstract

PURPOSE:To make the projection of a work into automation, by superposing a conveyor belt, which transfers the work fed out of a preceding step processing device up to a turnover part, on a conveyor belt transferring it from the turnover part to a latter processing device for their synchronization. CONSTITUTION:A driving sprocket 3 of a weighing device 1 is driven in an A direction by a motor 6 via a transmission mechanism 7 and thereby the upper side of a chain belt 5 is made to travel in an S1 direction. In this case, at the upper part of the weighing device 1, an aligning conveyor 10 is installed in sameness in an extending direction of the said device 1 and free of movements in all directions. And, a driving shaft 11 of the said conveyor 10 is rotated in a B direction by the motor 6 via the transmission mechanism 7 and thereby the lower side of a belt 13 is made to travel in an R1 direction. With this constitution, a measured work H is conveyed by the said belt 13 and, after being guided and turned over by a guide plate 15 at a turnover part T, the measured work is smoothly delivered to the chain belt 5 synchronizing with the belt 13 and then projected inside a weighing mechanism 8.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic loading device for automatically loading workpieces such as saury and tuff one into a weight sorting device for sorting marine products, agricultural products, etc. by weight.

As is well known, in the work of sorting the weight of objects to be measured.

Conventionally, a person is placed on the feeding side of a multi-stage sorting device that sorts objects to be measured according to their quality, and this person selects the objects to be measured (for example, Sanman) into the work input port of the multi-step sorting device. However, with this conventional method, it is difficult to reliably align and place the objects to be measured on the moving surface of the multi-stage sorting device, and the workpiece feeding efficiency is also poor. In view of the above points, the present invention provides an automatic loading device that can automatically and smoothly load workpieces into a multi-stage weight sorting device, and can reduce the installation space. It is an object.

In order to achieve this object, the automatic loading device according to the present invention is arranged overlapping a post-processing device that processes the work while transporting the work by a first belt, and transfers the work supplied from the pre-processing device to the second processing device. a conveyor for transporting the workpiece by the belt of the workpiece, discharging the workpiece from the workpiece input section, and placing the workpiece on the first belt; The portion of the second belt that faces the work input section is in the same transport direction, and the portion of the second belt that faces the workpiece input section is in the same transport direction, and It is characterized by comprising a synchronizing means for synchronizing the second belt.

Hereinafter, the present invention will be explained according to embodiments shown in the drawings.

FIG. 1 is a side view of an automatic loading device according to the present invention, and FIG. 2 is a top view of the same device. In these figures, 1 is a weighing device, and a driving sprocket 3 and a driven sprocket 4 are provided at both ends of the weighing device 1, and a chain band 5 is hung between the driving sprocket 3 and the driven sprocket 4. There is. The driving sprocket 3
is rotated in the inward direction by the driving force of the mower 6 supplied via the transmission mechanism 7, and when it rotates in the A direction, the upper side of the chain band 5 is rotated in the direction S.

A large number of pawls 5a provided on the outer periphery of the chain band 5 move in the 81 direction. Further, a weighing mechanism 8 is provided near the driven sprocket 4. This weighing mechanism 8 sorts the objects to be measured placed on the chain band 5 according to their weight, and the objects to be measured are transferred to a discharge conveyor 9 passing through the weighing mechanism 8 according to the weight measurement result. It is distributed to each belt and sent to the next work station.

Further, an alignment conveyor 10 is provided above the weighing device 1 so as to be movable back and forth or left and right in the same direction as the weighing device 1 described above. This alignment conveyor 1
0 has a driving shaft 11 and a driven shaft 12 at both ends, and a belt 13 is placed between these shafts, and the surface of this belt 13 has claws that protrude in accordance with the width of the object to be measured. 13a is provided all around the circumference.

The drive shaft 11 is rotated in the B direction by the motor 6 and a transmission mechanism 14 that transmits the driving force of the motor 6, and runs in the lower R8 direction of the belt 13, and half covers the drive shaft 11. In this way, the guide plate 15 is provided. The guide plate 15 covers the portion of the belt 13 that is reversed in a semicircular shape), and the guide plate 15 prevents the object to be measured transferred by the belt 13 from falling to a place other than the desired place. ing. Further, the motor 6 is connected to the belt 13 via transmission mechanisms 7 and 14.
and the chain band 5 are run at synchronized speeds), so that the objects to be measured falling from the alignment conveyor 1o fall onto the claws 5a of the chain band 5.

Therefore, when the object to be measured H is placed on the alignment conveyor 10, after moving in the R2 direction on the belt 13 of the alignment conveyor 1°, the object to be measured H is covered by the ID plate 15 until it is reversed by the reversing part molecule. The object to be measured is not emitted to the outer periphery. After this, the object to be measured H is placed at the end of the guide plate (workpiece discharge section) 1, 5. Pell with e:)'13 and is placed on the claw 5a of the chain band 5 of the weighing device 1. At this time, since the opposing sides of the chain band 5 and the belt 130 are driven synchronously at the same speed, the object to be measured H is transferred smoothly and reliably from the alignment conveyor 10 to the weighing device 1. . Next, the object to be measured (2) placed (delivered) into the weighing device 1 is transferred by the chain band 5, its weight is measured from the outside, and it is placed on one of the belts of the discharge conveyor 9 according to the measurement result. and transported to the next work site.

As explained above, the automatic loading device according to the present invention transfers the workpieces supplied from the front processing device using the second belt, and then transfers the workpieces from the workpiece loading section to the conveyor that discharges the workpieces from the conveyor. The workpieces are placed one on top of the other on a post-processing device that is transported by a first belt, and a synchronization means causes the parts of the first and second belts facing the workpiece inputting section to move in the same direction. Since the conveyor and the conveyor are substantially synchronized, the work can be automatically and smoothly transferred from the conveyor to the downstream processing device, and the installation space can be reduced.

Furthermore, it is advantageous for maintenance if the conveyor is moved vertically and horizontally.
