Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for automatically sorting, sorting, and collecting long vegetables such as radish and carrots and other materials to be sorted.

[Prior Art] Conventionally, in this type of sorting device, automatic weighing of objects to be transported and classification of objects by weight rank have been automatically performed. In other words, the conveyed object is on the conveyor belt! ! While transporting the heald, the amount of deflection of the heald based on the weight is detected and the weight is measured.Based on the measurement result, the corresponding weight rank among the multiple collection containers is sent from the top of the transport belt through the chute. The objects to be transported collected in the collection container are manually stored in separate packaging cases at a predetermined number or by a predetermined total weight at another location.

[Problem to be solved by the invention]

However, in the above-mentioned conventional technology, the work of transferring the materials from the collection container to the packaging case is cumbersome and contributes to a decrease in overall work efficiency, and automation of such work has been desired.

An object of the present invention is to enable efficient sorting and distribution work for each predetermined collection and supply amount of sorted materials.

[Means to solve the problem]

The characteristic configuration of the present invention is that after the objects stored in the hopper are carried out one by one at intervals by a carry-out device, the weight of the objects is measured while being transported by a conveyor. In addition, a sorting section is provided for collecting and sorting each collection from the top of the conveyor through a sorting chute into the corresponding collection section of the plurality of collection sections based on the measurement results from the measurement section. The apparatus is provided with a stopper that releasably blocks the outlet of the corresponding sorting chute when a predetermined amount of transported objects is collected in the section.

[For production]

The weight of the objects to be conveyed, which are carried out one by one at intervals from the hopper, is automatically measured in the measuring section while being conveyed by the conveyor conveyor. The sorted items are automatically collected by the collection department.

Then, when it is determined that the amount of collection and supply to each collection section has reached a predetermined value based on the cumulative total of the measurement results of the measurement section, etc., the exit of the sorting chute to the collection section is blocked by a stopper. A state is maintained in which a predetermined amount of objects to be sorted are collected in the collection section.

〔Effect of the invention〕

As a result, only the predetermined amount of conveyed objects is always collected in the collecting section, eliminating the need for workers to carry out unnecessary transfer and weighing work, improving the efficiency of the overall sorting work. This made it possible to reduce labor costs.
