Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a method of sorting articles into respective sorting destinations, taking into consideration that the upper and lower postures are not disturbed, since various treatments are applied to the upper surface like articles, especially sweet bread. It is suitable.

[0002]

2. Description of the Related Art As a conventional sorting technique for bread and the like, for example, Japanese Patent Application Laid-Open No. 4-223902 and Japanese Patent Application Laid-Open No. 5-223902.
It is disclosed in Japanese Patent No. 229638. In the technical contents disclosed in the former gazette, the display of the type of bread, etc., the sorting destination, the sorting quantity, etc. is clearly shown on the display, but the sorting work based on this display depends exclusively on manual work. ,
This is completely different from the present invention of automating the sorting work, and the technical content disclosed in the latter publication is that if the sorting number is equal to or larger than the reference number, from the mass conveyor,
If the number is less than the reference number, the small-quantity conveyors are transferred to the respective transport lines and transported in block units to a sorting partner having a plurality of sorting destinations as one block.

[0003]

In the former prior art described above, since the sorting work depends exclusively on the manual work, it is difficult to avoid human error in the sorting number due to carelessness and the reliability of the sorting number. Not only is it lacking, but the labor and time required for the work become too large, and the work efficiency can be improved, and in the latter prior art, the product sorting by container unit by the large-quantity product conveyor and the small-quantity product conveyor are performed. Since the sorting of the number of articles less than the container unit is all sorted as a unit of the total number of articles for each sorting partner with a plurality of sorting destinations as one block, the articles sorted into each block are included in each block. Since it is necessary to sort again according to the sorting destination store of the above by manual work as explained in the former conventional example, the same drawbacks as the above-mentioned former There was.

[0004]

SUMMARY OF THE INVENTION Therefore, according to the present invention, a container unit article carrying line for stacking a large number of containers each containing a fixed number of articles for each terminal sorting destination and transporting them to a sorting yard, and A fractional article carry-in line that conveys a container for each end sorting destination that stores fractional goods, and a large number of containers for each end sorting destination that have been loaded into the sorting yard from each of the loading lines are accumulated at each end sorting destination. The problem of the prior art is solved by a sorting system having an end accumulation line.

[0005]

[Function] Since a large number of containers are carried into the sorting yard by the number-of-container item-carrying-in line and the fraction-carrying-item-carrying line, all the containers of each terminal are stored in container units. By accumulating at the end sorting destination of the container, a desired number of articles are sorted at each end sorting destination. Therefore, by managing the end sorting destination of each container by the CPU, it becomes possible to sort articles that do not depend on manual work.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a diagram for explaining the method of the present invention. When the sortable articles are confectionery breads, 1 is a package and a container arranged at the end of the Anpan production line. A container storage device for storing, similarly, 2 is a cream bread packaging and container storage device, 3 is a jam bread packaging and container storage device, and a container storing a certain number of containers is a stacking machine 1 ', 2'for each end sorting destination. And 3 ', respectively.

The containers 4A thus stacked are delivered to the container unit carrying-in line 5, and when the number of articles sorted to each terminal sorting destination is less than the number of container units, that is, a fraction less than a certain number. Loads the stacking container 4B, which stores the number of articles equal to or more than the total of the fractions of the respective end sorting destinations, into the fractional article sorting line 6A.

Since the number of non-standardized special-shaped irregular-shaped breads is smaller than that of standard-shaped breads, a special-shaped article delivery line 7A for storing the total number of end-sorts in a container is required. It may be provided accordingly.

Number of Container Units The stacked containers 4A carried into the article carrying-in line 5 are mounted in a sorting yard 8 on, for example, a trackless automatic guided vehicle A, and are stacked for each sorting block to which an end sorting destination of the container belongs. Into each of the sorting blocks G1 to G4, a large number of end sorting destinations are arranged so as to face the sorting yard 8.

Since the large number of containers accumulated in each of the sorting blocks G1 to G4 have already been sorted by the end sorting destination, they are stacked by the transfer vehicle D in each block by the designated end sorting destination. .

On the other hand, the container 4B carried into the fractional goods sorting line 6A reaches a fractional sorting machine M such as a robot. Since a circulating conveyor C having a large number of slats on which empty containers with designated end sorting destinations are placed is disposed on the side of the fraction sorting machine M, the articles in the fraction article storage container 4B are fraction sorted. At the position of the machine M, the fraction sorting machine M throws the number of articles corresponding to the fraction to be sorted into the end sorting destination into each end sorting destination empty container.

The end-sorting containers into which the fractional number of articles have been put are placed on the slats, stacked at a predetermined position, and carried into the sorting yard 8 through the fractional article carrying line 6B. The container delivered in the irregular-shaped article delivery line 7A also has the irregular-shaped article carry-in line 7 in the same manner as the fractional article.
At B, it is carried into the sorting yard 8.

The loading lines 6B and 7 are placed in the sorting yard 8.
The container carried in via B is already classified as an end sorting destination like the container carried in from the above-mentioned container unit number article loading line 5, so that each designated end sorting destination is passed through the end collecting line 9. Accumulated. Then, the sorted articles accumulated for each end sorting destination are sorted and loaded for each end sorting destination on the truck T waiting at the exit.

In the figure, the standby article stock yard S is temporarily loaded into the stock yard S without being sent to the carry-in line when articles in excess of the number to be sorted are sent from the manufacturing line, Further, when the number of articles sent from the production line is slightly less than the number of articles to be sorted, it has a function of supplying from the stockyard S.

The respective end containers are input to the central control CPU of each container, and the containers are sorted to the corresponding end distributor based on a command from the CPU without manual work.

A block diagram of the above-described sorting system of the present invention is illustrated in FIG. That is, a fixed number of the packaged articles are stored in each container, the respective containers are sorted according to each end sorting destination and stacked and loaded into a sorting yard, while the fractional number of articles below the fixed number is set. It is stored in each end-sorting container having the fraction and carried into the sorting yard, and a fixed number of item storage containers having the same end-sorting destination and fractional number-of-items storage containers are accumulated in the end-sorting destination. And then shipped.

For example, when 50 items are stored in one container, the end-sort destination stores A, B, C ...
Assuming that there were many stores in
Assuming that 23 items, 315 items in the B store, and 117 items in the C store are sorted, first, the A store stores 50 containers in four stages, and the B store stores 50 containers in 6 stages. In the C store, 50 containers are stacked in two stages in the C store, and the containers stacked in a total of 12 stages are loaded into the sorting yard 8 through the item loading line 5 while the end sorting destination is not specified. The individual containers are stacked in two stages and conveyed to the fraction sorting machine M via the fraction item sorting line 6A.

In the fraction sorter M, the ampan is stored with a fraction of 23 for the A store container and a fraction of 15 for the B store container.
Each of the C and C stores holds 17 fractional items. Next, if the cream bread is sorted and conveyed from the production line to each store in the same number as the ampan, it is divided into a container unit number and a fraction like the case of the ampan, and the fraction is a fractional container containing the ampan. The containers additionally stored in the container, which store the numbers of the respective end-sorted leading ends and the number of articles, are stacked and loaded into the sorting yard 8 through the fractional-item loading line 6B.

In the sorting yard 8, the containers carried from the container unit number article loading line 5 and the containers loaded from the fractional article loading line 6B are respectively sent from the A store sorting position via the end accumulation line 9 according to a command from the CPU. In each of them, four containers each containing 50 breads of anpan and cream bread, a total of 46 containers of 23 pieces of fractional bread and 23 pieces of fractional cream bread are accumulated, and at the B store, anpan bread,
Each of the cream buns has a container of 50 pcs, 6 tiers each, a round ampan and a total of 30 buns of cream buns.
In the store, two containers each containing 50 pieces of Anpan and cream bread are stacked in two stages, and a container containing 34 pieces of Anpan and cream bread in total. The other stores are similarly accumulated.

[0020]

Industrial Applicability According to the present invention, the number of articles sorted to the terminal sorting destination is sorted into the number sorted into the constant article storage container unit and the number sorted into the fraction less than the constant to sort the container unit number articles. Each container is sorted by end-sort and stacked and loaded into a sorting yard.When sorting by fraction, the number of each end-sort is stored in the end-sort container and sorted by the sorting yard. Since a large number of containers are loaded into the sorting yard, end containers are already specified for each container, and by accumulating these containers at each end container, a predetermined number of articles are Since it is sorted into the sorting destination, it is not necessary to rely on manual work in the sorting work at the end sorting destination, as in the above-mentioned latter conventional example, and therefore the work of the article There is no possibility that sorting errors occurs, moreover, a sorting system that can realize an accurate sorting greatly reduce the sorting labor and sorting time.
