Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a returned book processing method and a processing apparatus for taking out returned books contained in a packing box and automatically totalizing them for each packing box so as to clarify the separation from the next packing box.

[0002]

2. Description of the Related Art Generally, books such as magazines, books, and comics are sold by consignment, and unsold books sold at stores are paid by returning them to the publisher within a predetermined period. There is no need to pay the publishers only for the quantity sold and the quantity not returned in time.

However, since the returned book is no longer worthwhile, it is not actually returned to the publisher but collected at the returns center and handed over to the used paper manufacturer as it is, and the publisher only receives the slip. Sending is done. The publisher trusts the slip from the return center without confirming the return from the store and performs necessary processing based on this slip. As a result, it is not necessary to return the return book to the publisher from a remote place, for example, and the return book can be returned to the local return center, so that the total cost can be reduced.

[0004] Conventionally, as a device for automatically sorting returned books, for example, in Japanese Unexamined Patent Publication No. 8-20426, the retailer code displayed on the packaging box is read, and the returned books discharged from the packaging box are By sending to the cutting conveyor set so that the speed gradually increases as it moves upward, the returned books discharged at one time are cut out one by one and displayed on the cut out returned book. A technology is disclosed in which a bar code is read, necessary information such as the publisher and type of the returned book is recognized, the returned book is sorted according to the recognized information, and a slip for each store is created.

[0005]

By the way, the packaging box for accommodating the returned books is, after being continuously carried on the conveyor,
It is sequentially discharged by the worker to the cutting conveyor. At that time, the operator reads the bookstore code attached to the packing box by a bar code and collects the returned books for each bookstore. However, during a long work, the worker forgets to read the bookstore code attached to the new packaging box, and the return book in the previous packaging box is followed by the return book in the new packaging box. May be sent out.

If there is such an error in work, the type and quantity of the book returned from a specific bookstore are confused with the type and quantity of the book returned from the next bookstore. It is difficult to create a slip with a large quantity.

Therefore, an object of the present invention is to provide a returned book processing method and a processing apparatus which prevent confusion of returned books ejected from one packaging box and returned books ejected from the next packaging box. To provide.

[0008]

In order to achieve the above object, a first method of processing returned books according to the present invention comprises a step of weighing the total weight of a packaging box accommodating a plurality of returned books,
The calculation means includes a step of reading the store code displayed on the packaging box, a step of cutting out a plurality of returned books taken out from the packaging box, and a step of weighing each of the cut out returned books. Compare the added value of the total weight of each returned book and the empty weight of the packaging box with the total weight, and when the absolute value of the difference falls within the set range, all the items taken out from one packaging box It is characterized in that it is determined that the return book transfer has been completed, and that the weight data of the return book to be input thereafter is determined to be from the next packaging box.

In the present invention, the returned book means a book such as a magazine, a book, or a comic book, which has been unsold at each bookstore and has been returned.

The second method for processing returned goods is characterized in that in the first method for processing returned goods, a step of weighing out the empty weight of the packing box after taking out all the returned books from the packing box is provided. And

The third method for processing returned goods is the first or the second.
In the return book processing method, the computing means completes the transfer of all the return books taken out from the packaging box, and before the next store code is entered, the magazine taken out from the next packaging box is When it is determined that the transfer system has been transferred, the transfer system is stopped.

The first returned book processing apparatus according to the present invention is a weighing scale for weighing the total weight of a packaging box accommodating a plurality of returned books, and a reading for reading the store code displayed on the packaging box. Means, a feeding conveyor that is adjacent to the weighing scale and takes out the returned book from the packing box and places it, a feeding conveyor that is adjacent to the feeding conveyor and has a speed that gradually increases as it moves downstream, and the cutting With a scale conveyor that individually weighs the weight of the returned books cut out by the conveyor, and the sum of the total weight of the returned books weighed by the scale conveyor and the empty weight of the packaging box, use the above scales. Compared with the total weight weighed, when the absolute value of the difference falls within the set range, it is judged that all the returned books taken out from one of the above packaging boxes have been transferred, and the returned goods to be entered thereafter The weight data, characterized in that it comprises a determining operation means with those from the next packaging.

A second returned book processing apparatus is characterized in that, in the first returned book processing apparatus, the weight scale weighs the empty weight of the packing box after all the returned books are taken out.

The third returned-goods processing apparatus is the first or second
In the returned book processing apparatus, the computing means completes transfer of all returned books taken out from the packaging box, and before the next store code is entered, the magazine taken out from the next packaging box When it is determined that the transfer system has been transferred, the transfer system is stopped.

That is, according to the first method for processing returned goods, the total weight of the packaging boxes transported to each store is first weighed with the returned books stored, and the packaging boxes are also shipped. Scan the store code displayed on. Next, the return book is taken out from the packaging box, cut out, and the cut out return book is sequentially weighed. Then, in the calculation means, the added value of the total value of the weight of the weighed returned books and the empty weight of the packaging box is
Compared with the total weight of the packaging box, when the absolute value of the difference is within the setting range, it is determined that all the returned books taken out from one packaging box have been transferred, and the weight of the returned books to be entered thereafter. The data is determined to come from the next packaging box. As a result, it is possible to automatically detect the division between the return book of one packaging box and the return book of the next packaging box.

In the second method of processing returned books, all the returned books are taken out from the packing box and the empty weight of the packing box is weighed so that the empty weights of the packing boxes are different from each other. can do.

In the third method of processing returned books, after it is judged that the transfer of all returned books taken out from the packaging box is completed,
If the magazine taken out from the next packing box is transferred before the next store code is entered, the transfer system should be stopped and the books in different packing boxes should be confused and aggregated. Can be prevented.

Further, according to the first returned book processing apparatus, the total weight of the packaging boxes conveyed to each store is first weighed by the weight scale while the returned books are stored, and ,
The store code displayed on the packing box is read by the reading means. Then, when the returned books taken out from the packing box are placed on the input conveyor, they are transferred to the cutting conveyor adjacent to the input conveyor, and the returned books are separated and sent out one by one. Further, the weight of the returned books separated for each book is individually measured by the scale conveyor. Then, the calculating means compares the added value of the weight of each returned book weighed on the scale conveyor and the empty weight of the packaging box with the total weight weighed on the weighing scale, and the absolute value of the difference is within the setting range.

The total weight Wt, the empty weight We, and the bar code reader 1 of the packaging box 1 are connected to the monitor of the terminal 12.
The store information etc. corresponding to the store code read by 3 are displayed.

The rollers constituting the cutting conveyor 7 are set so that the speed thereof gradually increases as they move upward, so that each returned book 1a discharged to the cutting conveyor 7 has a horizontal conveyor 8 above it. When moved to the side, they are cut out (see FIG. 2).

Then, the return book 1a sent to the horizontal conveyor 8 has the scale conveyor 9 interposed in the middle thereof.
When moving up, the returned book weight Wb is measured one by one.

Further, the return book 1 is provided directly below the bar code reader 11 for return books which is provided above the horizontal conveyor 8.
When "a" passes, the bar code (not shown) displayed on the return book 1a is read, collated with the data stored in the host computer 15, and the publisher of the return book 1a returns the goods. Recognize returned book information such as the type of book and whether the collection period has expired. Also, if the barcode cannot be recognized, it is treated as a barcode error.

The return book 1a identified by the bar code is sorted in a predetermined manner through a gate that is connected to the sorting conveyor 10 according to the type of the return book, and the return book is judged as a bar code error. 1a is automatically returned to the worker.

On the other hand, the total weight Wt and the empty weight We of the packaging box 1 read by the terminal 12, the sales code read by the bar code reader 13 for the store, and the bar code reader 11 for the returned book are read. Returns This code is
It is output to the host computer 15.

The host computer 15 controls the opening / closing timing of gates for sorting return books and automatically returns the return book 1a taken out from the packaging box 1 and the return book taken out from the next packaging box. Divide and pack 1
The type and total number of returned books are totaled for each.

The totalization by the host computer 15 is specifically processed according to the flowcharts shown in FIGS.

In the return book automatic sorting routine shown in FIG. 3, first, the total weight Wt of the packaging box 1 is read in step S1, and the return book weight Wb is read in step S2. And
The process proceeds to step S3, and the integrated value Wt of the returned product weight Wb is Wt.
Calculate b (Wtb ← Wtb + Wb). The integrated value W
The initial value of tb is 0.

Then, the process proceeds to step S4, and it is checked whether or not the empty weight We of the packaging box 1 is read. here,
If the empty weight We has not been read, the process returns to step S2 and the returned product weight Wb is read again. Empty weight We
Is being read, the process proceeds to the next step S5.

In step S5, the absolute value of the value obtained by subtracting the empty weight We and the integrated value Wtb from the total weight Wt and the set value W
When compared with o, when | Wt-We-Wtb |> Wo, all the return books 1a accommodated in one packaging box 1 have not been measured yet, so the process returns to step S2 to return the return book again. Read the weight Wb.

If | Wt-We-Wtb | ≤Wo, it is within the error of the total weight Wt, so it is determined that all the returned books 1a contained in the packing box 1 have been measured, and step S6 is performed. Proceed to and set the return measurement flag F (F ←
1) The process proceeds to step S7, the integrated value Wtb is cleared (Wtb ← 0), and the process proceeds to step S8.

The set value Wo is a value indicating an error range, for example, 50 g, and is set to a value lighter than the minimum weight of one returned book 1a.

Then, in step S8, it is checked whether or not the next store code is input, and when the next store code is input, the routine is finished as it is.

On the other hand, if the next store code has not been entered, the process proceeds to step S9, and it is checked whether or not the return book weight Wb is continuously read. Then, if the returned book weight Wb has not been read, the process returns to step S8 to check again whether or not the store code is input. By going back and forth between steps S8 and S9,
The system will wait until the store code is entered.

On the other hand, when the return weight Wb is continuously read, after the system is stopped,
Exit the routine. That is, the worker is the packing box 1
After returning the return book 1a stored in the input box to the input line B, the return book stored in the next packaging box is continuously input to the input line B. At that time, forgetting that, If the store bar code displayed on the packaging box is not read, the system will be automatically stopped.
This makes it possible to prevent the return book of the present packaging box and the return book of the next packaging box from being confused and aggregated.

When all the return books 1a contained in the packing box 1 are sorted, the return book information output routine shown in FIG. 4 is started, and first, in step S11, the return book information is read and continued. In step S12, referring to the value of the returned goods main measurement flag F, when it is cleared, all the returned books 1a have not been transferred yet, so the process returns to step S11, and when set, packing is performed. Since all of the returned books 1a contained in the box 1 have been transferred, the process proceeds to step S13, the store code is read, and step S
Proceeding to 14, the return information for each store is output to the storage device and stored therein, and is output via the printer 16 to create a slip for each packaging box 1.

The present invention is not limited to the above-described embodiment. For example, when the empty weight We of the packaging box 1 is a predetermined constant value, it can be input as data in advance. Since it is not necessary to measure the empty weight We successively, workability is improved.

[0053]

As described above, according to the present invention,
Compare the difference between the total weight of the return box before taking out the returned book and the accumulated value of the returned book after discharge and the empty weight of the return box. When the difference is within the specified range, take out from the one return box. Since it has been decided that the transfer of all returned books has been completed, it will automatically recognize the separation between the returned book ejected from one packaging box and the returned book ejected from the next packaging box. This makes it possible to prevent errors in counting and improve workability.
