Abstract

PURPOSE:To surely and precisely input sorting data in a device for sorting a large number of cargos, by enabling sorting data on a tag applied on a cargo at two different side surfaces of the cargo so that data on either one of the side surfaces is used for sorting the cargo. CONSTITUTION:A sorting number of a tag (not shown) applied on each of cargos which are one by one delivered into a sorting number input room 41 from cargo pooling vehicles 5, is read by optical character readers OCR 43, 44. These optical characters are arranged such that the OCR 43 optically scans on the upper surface of the cargo while the OCR 44 optically scans one side surface of the cargo to read data thereon. Accordingly, if the tag is applied on the upper surface the OCR 43 reads the sorting number and delivers the same to a control section. If no tag is on the upper surface, the OCR 44 read data and deliver the same to the control section. With this arrangement, the input of a sorting number is rapidly and precisely made.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a baggage sorting device, and particularly relates to an improvement of a baggage sorting device that receives a large amount of baggage and sorts it according to classification categories.

[Technical background of the invention and its problems] This type of baggage sorting device is installed at a terminal, for example, in a courier system for centralized sorting, and receives multiple parcels collected at each reception center. sorted by region of destination.

Therefore, when a customer's (requester's) package is collected at each reception center of the courier system, such as a store designated as a courier service center, for example, as shown in Figure 8 or 9, , date 1 [Ja, delivery number @ column b, delivery address and client's address, name, etc. column 01 product name column d1 entry column e for baggage handling store, etc. Luggage tag 1 (see Figure 9) First, attach the journal number entry frame f) to the luggage.
As shown in FIG. 10 or 11 for each region, the journal number 3 is written by hand with a felt-tip pen in a color that does not interfere with the printing of the tag 1, for example, red.

Next, the baggage with the tag 1 on which the journal number 3 has been written is transferred by a collection vehicle to the terminal for intensive sorting, and the concentrated sorting is carried out at the terminal, and the large-scale baggage sorting is carried out by a device.
The parcels will be sorted by destination area, and the schematic configuration of the device for sorting the parcels is shown in Figure 7.

In FIG. 7, reference numeral 5 indicates a collection vehicle loaded with packages from reception centers in various locations. Luggage is unloaded one by one from the collection vehicle 5, and placed on the carry-in conveyor 7 with the tag positioned on the top or one side.

The packages placed on the carry-in conveyor 7 are sent to the main conveyor 9 by each of the plural carry-in conveyors 7, and are sent to the journal number input room 1.
Moved to 1.

In the journal number input room 11, a staff member looks at the baggage being moved by the main conveyor 9 and enters the journal number written on the baggage tag (see Figures 10 and 11) by key-in operation on the operation panel 13. The signal is then input to the drive control system of the layer conveyor 15 and its associated mechanisms.

Therefore, when the cargo sent from the main conveyor 9 to the pallet 17 of the layered conveyor 15 is moved to the position indicated by the journal number according to the rotation of the layered conveyor 15 in the direction of the arrow, It is transferred to a conveyor 19, and loaded onto a delivery vehicle 21 from this carry-out conveyor 19.

As described above, in the conventional system for sorting packages, what is not automated is the work performed by the clerk in the journal number entry room 11.

As mentioned above, the staff member's duties in the journal number input room 11 are as follows: For the parcels that are sent one after another by the main conveyor 9, the clerk H reads the journal number on the tag and inputs it to the operation panel 13. It is quite a labor-intensive task as it requires key-in input.

In particular, this type of work is often carried out in the evening and night hours rather than during the day, so we must constantly be on our toes to ensure that we do not misread the journal number and that there are no erroneous key-ins. Coupled with the @magic occurrence that accompanies the work, there are times when it is not possible to sort the items properly.

In view of the fact that such sorting work, which requires a large mental load, exists in conventional systems, the present invention was completed. .

[Object of the Invention] An object of the present invention is to provide a baggage sorting device that can quickly and accurately input journal information into a control system.

[Summary of the Invention] In order to achieve the above object, the baggage sorting device of the present invention writes predetermined journal information using a writing instrument on a sheet of paper in which the region on which the journal information is written is designated by a printing frame. means for feeding the package to which the predetermined journal entry information has been given to a certain position; first reading means for reading out the predetermined journal entry information from the first side of the package that has been supplied to the certain position; a second reading means for reading out the journal entry information from the second side when the predetermined journal information cannot be read out by the first reading means; The present invention is characterized by comprising means for sorting the packages in accordance with sorting information.

[Embodiments of the Invention] FIG. 2 is a diagram showing the format of a tag created for a baggage sorting device to which the present invention is applied.

This tag 31 is an improved version of the conventional tag (see Figure 9), and provides certain conditions such as coloring and reflection in the journal number entry frame. If the color of the writing instrument used to write the journal number is black, print the journal number entry frame f with visible long wavelength reflective ink such as red or yellow; Print with visible long wavelength absorbing ink such as black.

In addition, in the journal number entry frame f, each entry frame f1 to t4
are for entering one character of the journal number, respectively, and entry frame f1. F2 contains the parent number (prefecture) of the journal number, and entry frame f3. In the same f4, the journal number (city, town, village)
write.

The tag 31 created in this way is attached to the baggage, and the journal number is written in the journal number entry field with a writing instrument.Then, the baggage given this journal number is transferred to the terminal for centralized sorting. This centralized sorting is carried out at the terminal, and the baggage sorting shown in FIG. 1 is sorted by region according to destination.

FIG. 1 is a diagram showing a schematic configuration of a baggage sorting apparatus to which the present invention is applied. In the figure, 41 is a journal number input room, and this journal number input room 41 is equipped with an optical character reader (hereinafter referred to as a (called OCR)
43 and 44 are installed.

First, the 0CR43 scans the top side of the package, thereby reading the journal number written in the journal number entry frame r of the tag 31. When this reading is performed, the control system is sent from the 0CR43. The journal entry number is entered.

Since there is no tag 31 on the top of the baggage, 0CR4
3, when the journal number on the tag 31 could not be read, the 0CR44 scans one side of the parcel, and when the journal number written on the tag 31 is read, the read journal number is Input to control system.

That is, the packages are unloaded one by one from the collection vehicle 5 and placed on the carry-in conveyor 7 with the package tag 31 on which the journal number has been written positioned on the top or one side. It will be read out.

At this time, as shown in FIG. 2, the tag 31 has a journal number entry frame printed in bold on the top and left side of the body, so it is convenient to recognize the direction of the tag 31.

Each 0CR43 and 0CR44 has an integrated structure, and the third
As shown in the figure, scanners 47 and 49 optically scan light on the top surface 45A and one side surface 45B of the package 45, and a frame signal is generated by receiving an output signal from either one of the scanners 47 or 49. and a signal processing circuit 51 that outputs character signals, and a recognition circuit 53 that reads journal numbers from these frame signals and character signals.

Then, the scanner 47 or 49 and the signal processing circuit 51
Specifically, the configuration is as shown in FIG. 4, for example.

In the embodiment shown in FIG. 4, when the journal number entry frame r of the tag 31 shown in FIG. 2 is printed in red, and the color of the writing instrument used to write the number in the journal number entry frame f is black. It is.

In order to optically scan the top surface or one side of the baggage 45, the light source 55 emits a red wavelength laser beam, and the light source 57 emits a green or blue laser beam.

Then, the optical axes of the two laser beams are brought together by a dichroic mirror 59 and guided to a polygon mirror 63 via a lens 61. Therefore, polygon mirror 6
The baggage 45 is scanned by the beam 65 scanned at 3.

Here, since the thickness of the baggage 45 varies from thin to thick, the role of the lens 61 is to prevent the shape of the beam irradiated onto the baggage 45 from changing.

Then, the light reflected by the surface of the luggage 71!5 is reflected by the polygon mirror 63, condensed by the condensing lens 67,
The light is guided to a red reflective dichroic mirror 69. The red component of the light guided to this red reflective dichroic mirror 69 is guided to a photoelectric element 75 through a red wavelength trimming filter 71. On the other hand, the light that has passed through the red reflective dichroic mirror 69 is guided to a photoelectric element 77 through a short wavelength trimming filter (for example, a blue transmission filter) 73.

In this way, the photoelectric elements 75 and 77 output electrical signals responsive to the amount of change in received scanning reflected light, and are applied to the binarization circuit 79.

In the binarization circuit 79, the added photoelectric elements 75 and 7
The analog electrical signal from 7 is converted into a binary code.

One of the converted binary codes 81 becomes a signal that does not include only the frame signal, and the other converted binary code 83 becomes a signal that includes both frames and numbers.

Therefore, in the differential amplifier circuit 85, the difference between the binary code 81 and the binary code 83 is calculated, and a signal 87 indicating only the red frame, a signal indicating the red frame, a signal corresponding to the journal number, and other printed characters are obtained. A signal 89 in which signals corresponding to the above are combined is output.

FIG. 5 schematically shows the signals of each part in the above electrical system. That is, as shown in <A) of the same figure, the journal number entry frame is a red frame 91, and the character 93 is written with a black writing instrument.
is written in the red frame 91, and if this central part is the center position 95 of laser scanning, then 81 to 81 are written in the same figure (B).
Signal waveforms of each part as shown in B6 are obtained.

That is, the signal waveform B2 is the output waveform of the photoelectric element 75, the signal waveform B3 is the waveform of the signal 83, and the signal waveform B4 is the waveform of the signal 81.
, signal B5 is the waveform of signal 89, and signal waveform 8B is the waveform of signal 87.

In this way, the output waveform of the photoelectric element 77, indicated by the signal waveform B1, is binary-converted in the 2 (unification circuit 79) into the waveform of the signal 83, indicated by the signal waveform B3.

Further, the output waveform of the photoelectric element 75 indicated by signal waveform B2 is as follows:
In the binarization circuit 79, as shown by signal waveform B4,
Only the component corresponding to the character has a large amplitude, and since the component corresponding to the frame is red, it is converted into a binary waveform of the signal 81 with a small amplitude.

Therefore, the waveform of the output signal 89 of the differential circuit 85 is shown as signal waveform B5 corresponding to the red frame, and the waveform of the other output signal 87 is shown as signal waveform B6 corresponding to the character. Become.

In this way, when the recognition circuit 101 receives the output signals 87 and 89 output from the differential circuit 85, recognition processing is executed in the recognition circuit 101 according to the processing flowchart shown in FIG. A monitor is displayed on a monitor display 103 such as a display.

In FIG. 6, in the first step (601), a frame signal 89 (see signal waveform B5 in FIG. 5) and a character signal 8
7 (see signal waveform B6 in FIG. 5) is stored in the memory. This is executed for all the entry frames f1 to f4 in FIG.

In the following step (603), it is determined whether or not there is a writing instrument in the entry frames [1 to [4].

If step (603) is affirmative, only the character signal is stored in another memory (step 605), and then the similarity between the character dictionary pattern and the character signal pattern is checked (step 607).

In the subsequent step (609), it is determined whether each of the characters in the entry boxes "1 to f4" matches the dictionary pattern.

If step (609) is affirmative, the journal number is transmitted to the control unit (step 611).

If the result in step (603) is negative, a frame signal and a character signal are added to the monitor, and only the entire area of the tag (see FIG. 2) is displayed on the entire monitor (step 613).

If the result in step (609) is negative, a frame signal and a signal that appears to be characters within the frame are added to the monitor, and only the frame and information within the frame are displayed on the entire monitor (step 61).
5).

In this way, when the journal number is recognized in 0CR43 or 0CR44, the cargo indicated by the journal number is transferred to the main conveyor 9.
When the peripheral conveyor 15 rotates in the direction of the arrow to the position indicated by the journal number, it is transferred to the carry-out conveyor 19 indicated by the journal number. From there, it is loaded onto the delivery vehicle 21. Note that the cargo loaded onto the delivery vehicle 21 is delivered to the destination by this delivery vehicle 21.

Further, in the journal number input room 41, for example, as shown in FIG. 7, an ITV camera 101 is installed in place of the ○CR 44, and an operation panel 103 equipped with a display such as a CRT and a keyboard is installed. .

Alternatively, as shown in FIG. 8, a line sensor 105 is installed in place of CR44, and the operator panel 1
By installing 03, the content scanned by the ITV camera 101 or line sensor 105 can be displayed on the monitor by the operator panel 103, and the journal number of the package can be calculated based on the content displayed on the monitor, without installing the oCR44. The operator panel 45 allows input to the control system.

In these embodiments, the tag is generally attached to the top of the package;
This was done considering the fact that it is rarely pasted on the side and OCR is relatively effective.

Note that when the rTV camera 101 images the side of the baggage, the baggage may be automatically rejected from the main conveyor 9 and left temporarily unattended, or one of the plurality of main conveyors 9 may be set to a reject-only one. It is preferable to use a conveyor to make the monitor display easier to see and to make it easier to supply rejected packages to the surrounding conveyor 15.

With this configuration, only one staff member is required for each of the main conveyors 9, and the staff member only has to key in the journal number for the parcels for which the journal number could not be recognized in 0CR43, reducing the burden on the staff member. It is significantly reduced, and night work becomes reliable and efficient.

In addition, in the example, two types of light emitting laser sources were used, but one
A similar effect may be achieved using separate laser sources that simultaneously emit red and green or blue wavelengths.

In addition, in the embodiment, the tag 31 is used as shown in FIG. 2, but instead of using this tag 31,
It is also possible to use a form consisting only of the journal number entry 11if attached to the old tag.

[Effect of the invention] If the baggage sorting device of the present invention as explained above is used,
Even if a package whose journal information is given by the form on which the journal information is written is arbitrarily fed to a certain position in one of two different states, the journal information of the baggage can be read quickly and accurately at that fixed position. At the same time, it is possible to sort packages according to the read journal information.

Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to a baggage sorting device, and particularly relates to an improvement of a baggage sorting device that receives parcels from bulk carriers and sorts them according to classification categories. [Technical background of the invention and its problems] This type of baggage sorting device is installed at a terminal, for example, in a parcel delivery system, and receives a large amount of baggage collected at each reception center. Sort by region of destination. Therefore, when a customer's (requester's) package is collected at each reception center of the courier system, such as a store designated as a courier handling center, for example, as shown in Fig. 10 or 11, Date A81 Arrangement number column B1 Notification is a loading tag 1 with entry of destination and client's address and name, etc., item name 11id, and entry of baggage handling store, etc. f) on the parcel, and the notification is handwritten in a color that does not interfere with the printing of tag 1, for example red, as shown in Figures 12 or 13 for each region. Write journal number 3. Next, the baggage with the tag 1 on which the journal number 3 has been written is transferred by a collection vehicle to the terminal for intensive sorting, and the concentrated sorting is carried out at the terminal, and the large-scale baggage sorting is carried out by a device.
The parcels will be sorted by region of destination, and the schematic configuration of the device for sorting the parcels is shown in FIG. 9. In FIG. 9, reference numeral 5 indicates a collection vehicle loaded with packages from reception centers in various locations. Luggage is unloaded one by one from the collection vehicle 5, and placed on the carry-in conveyor 7 with the tag positioned on the top or one side. The cargo placed on the carry-in conveyor 7 is sent to the main conveyor 9 for each carry-in conveyor 7, and is moved to the journal number input room 11. In the journal number input room 11, an attendant looks at the baggage being moved by the main conveyor 9, and enters the journal number written on the baggage tag (see Figures 12 and 13) by key-in operation on the operation panel 13. The signal is then input to the drive control system of the same-layer conveyor 15 and its associated mechanisms. Therefore, when the cargo sent from the main conveyor 9 to the pallet 17 of the same-layer conveyor 15 is moved to the position indicated by the journal number according to the rotation of the same-layer conveyor 15 in the direction of the arrow, the cargo is transferred to the pallet 17 indicated by the journal number. It is transferred to a conveyor 19, and loaded onto a delivery vehicle 21 from this carry-out conveyor 19. As described above, in the conventional system for sorting packages, what is not automated is the work performed by the clerk in the journal number entry room 11. As described above, the staff in the journal number input room 11 reads the journal numbers on the tags of the packages that are sent one after another by the main conveyor 9, and then inputs them on the operation panel 13. It is quite a hard labor as it requires key-in input. In particular, this type of work is often carried out in the evening and night hours rather than during the day, so if you don't constantly worry about misreading journal numbers and making sure there are no erroneous key-ins, it's simple. Coupled with the drowsiness that accompanies the work, I find it difficult to sort packages properly. In view of the fact that such sorting work, which requires a large mental load, exists in conventional systems, the present invention was completed. [Object of the Invention] An object of the present invention is to provide a baggage sorting device that can quickly and accurately input journal information into a control system. [Summary of the Invention] In order to achieve the above object, the baggage sorting device of the present invention writes predetermined journal information using a writing instrument on a sheet of paper in which the region on which the journal information is written is designated by a printing frame. means for feeding the package to which the predetermined journal entry information has been given to a certain position; first reading means for reading out the predetermined journal entry information from the first side of the package that has been supplied to the certain position; a second reading means for reading the journal information from a second side when the predetermined journal information cannot be read by the first reading means; and a means for sorting the cargo in accordance with sorting information. [Embodiments of the Invention] FIG. 2 is a diagram showing the format of a tag created for a baggage sorting device to which the present invention is applied. This tag 31 is a conventional tag (see Figures 10 and 11).
This is an improvement on the journal number entry frame ``, which provides certain conditions such as coloring and reflection.In other words, if the color of the writing instrument used to write the journal number in the journal number entry frame r is black. prints the journal number entry frame f with chromatic ink such as red, yellow, or blue, and if the writing instrument is red, prints it with chromatic ink such as blue. In frame r, each entry frame f1 to "4
are for entering one character of the journal number, respectively, and in the entry frame [I, f2 is the parent number (prefecture) of the journal number, and in the entry frame f3. Write the child number (city, town, village) of the journal number in r4. In the thus created luggage tag 31, the journal number is written in the journal number entry field f using a writing instrument while it is attached to the luggage. Then, the baggage given this journal number is transferred to the terminal for centralized sorting, and at the terminal, the baggage sorting as shown in Figure 1 is carried out by the equipment.
It is categorized by region of delivery. FIG. 1 is a diagram showing a schematic configuration of a baggage sorting apparatus to which the present invention is applied. In the figure, 41 is a journal number input room, and this journal number input room 41 is equipped with an optical character reader (hereinafter referred to as a (called OCR)
43 and 44 are installed. First, the top side of the package is scanned by ○CR43, and thereby the journal number written in the journal number entry frame f of the tag 31 is read out.When this reading is performed, the control is performed from the 0CR43. The journal number is entered into the system. And, because there is no tag 31 on the top of the baggage, ○CR4
3, when the journal number on the tag 31 could not be read, the 0CR44 scans one side of the parcel, and when the journal number written on the tag 31 is read, the read journal number is 1ill Input to ill system. That is, when the packages are unloaded one by one from the collection vehicle 5 and placed on the carry-in conveyor 7 with the baggage tag 31 with the journal entry number written on the top or one side, the movement of the carry-in conveyor 7 The parcel is fed to the sorting number input room 41. Regarding the luggage in the sorting number input room 41,
The journal number will be read in each 0CR43 and 0CR44. At this time, as shown in FIG.
This is convenient for recognizing the direction of the tag 31. In the above description, each of the OCRs 43 and 44 is integrated for each carry-in conveyor 7, and as shown in FIG. and 49, a signal processing circuit 51 that receives an output signal from either the scanner 47 or 49 and outputs a frame signal and a character signal, and a recognition circuit that reads the journal number from these frame signals and character signals. 53. Then, the scanner 47 or 49 and the signal processing circuit 51
Specifically, the configuration is as shown in FIG. 4, for example. In the embodiment shown in FIG. 4, when the journal number entry frame ``of the tag 31 shown in FIG. 2 is printed in red, and the writing instrument used to write the number in the journal number entry frame f is black In order to optically scan the top surface or one side of the package 45, the light emitting unit 55 emits a red wavelength laser beam, and the light source 57 emits a green or blue laser beam. , the two laser beams have their optical axes aligned by a dichroic mirror 59 and are guided to a polygon mirror 63 via a lens 61. Therefore, the polygon mirror 6
The baggage 45 is scanned by the beam 65 scanned at 3. Here, since the baggage 45 varies in thickness from thin to thick, the role of the lens 61 is to prevent the shape of the beam irradiated onto the baggage 45 from changing. The light reflected by the surface of the baggage 45 is reflected by a polygon mirror 63, condensed by a condensing lens 67, and guided to a red reflective dichroic mirror 69. The red component of the light guided to this red reflective dichroic mirror 69 is guided to a photoelectric element 75 through a red wavelength trimming filter 71. On the other hand, the light that has passed through the red reflective dichroic mirror 69 is passed through a short wavelength trimming filter (for example, a blue transmission filter).
73 and is guided to a photoelectric element 77. In this way, the photoelectric elements 75 and 77 output electrical signals responsive to the amount of change in received scanning reflected light, and are applied to the binarization circuit 79. In the binarization circuit 79, the added photoelectric elements 75 and 7
The analog electrical signal from 7 is converted into a binary code. One of the converted binary codes 81 becomes a signal that does not include only the frame signal, and the other converted binary code 83 becomes a signal that includes both frames and numbers. Therefore, in the differential amplifier circuit 85, the difference between the binary code 81 and the binary code 83 is calculated, and the signal @87 showing only the red frame, the signal corresponding to the journal number, and the signal corresponding to other printed characters, etc. A signal 89 in which the signals are combined is output. FIG. 5 schematically shows the signals of each part in the above electrical system. In other words, as shown in FIG.
is written in the red frame 91, and if this central part is the center position 95 of laser scanning, then 81 to 81 are written in the same figure (B).
Signal waveforms of each part as shown in B6 are obtained. That is, the signal waveform B1 is the output waveform of the photoelectric element 77, the signal waveform B2 is the output waveform of the photoelectric element 75, the signal waveform B3 is the waveform of the signal 83, the signal waveform B4 is the waveform of the signal 81, the signal B5 is the waveform of the signal 89, Signal waveform B6 is the waveform of signal 87. In this way, the output waveform of the photoelectric element 77 shown by the signal waveform B1 is binarized into the waveform of the signal 83 shown by the signal waveform B3 in the binarization circuit 79. Further, the output waveform of the photoelectric element 75 indicated by signal waveform B2 is as follows:
In the 2!1ffi conversion circuit 79, the signal is converted into a binary signal waveform as shown by B4. Therefore, the waveform of the output signal 89 of the differential circuit 85 is shown as the signal waveform B5 corresponding to the red frame, and the waveform of the output signal 87 in its usage is shown as the signal waveform B6 corresponding to the character. become. In this way, when the recognition circuit 101 receives the output signals 87 and 89 output from the differential circuit 85, recognition processing is executed in the recognition circuit 101 according to the processing flowchart shown in FIG. A monitor is displayed on a monitor display 103 such as a display. In FIG. 6, in the first step (601), a frame signal 89 (see signal waveform B5 in FIG. 5) and a character signal 8
7 (see signal waveform B6 in FIG. 5) is stored in the memory. This is executed for all the entry frames f1 to r4 in FIG. In the following step (603), it is determined whether there is any writing with a writing instrument within the entry frames f1 to f4. If step (603) is affirmative, only the character signal is stored in another memory (step 605), and then the similarity between the character dictionary pattern and the character signal pattern is checked (step 607). In the following step (609), it is determined whether each of the characters in the entry frames f1 to f4 matches a dictionary pattern. If step (609) is affirmative, the journal number is transmitted to the control unit (step 611). If the result in step (603) is negative, a frame signal and a character signal are added to the monitor, and only the entire area of the tag (see FIG. 2) is displayed on the entire monitor (step 613). If the result in step (609) is negative, a frame signal and a signal that appears to be characters within the frame are added to the monitor, and only the frame and information within the frame are displayed on the entire monitor (step 61).
5). In this way, when the journal number is recognized in 0CR43 or 0CR44, the cargo indicated by the journal number is transferred to the main conveyor 9.
When the pallet 17 of the same-layer conveyor 15 is conveyed to the pallet 17 of the same-layer conveyor 15 and moved according to the rotation of the same-layer conveyor 15 in the arrow direction to the position indicated by the journal number, it is transferred to the carry-out conveyor 19 indicated by the journal number, and this carry-out It is loaded onto the delivery vehicle 21 from the conveyor 19. In addition, the packages loaded on 21 during delivery are this delivery I! 21 will be delivered to the destination. In addition, the journal number input room 41 may also include, for example, an ITV camera 101 and C instead of 0CR44, as shown in FIG.
An operator panel 103 equipped with a display such as RT and a keyboard is installed. Alternatively, as shown in FIG. 8, a line sensor 105 is installed in place of 0CR44, and the operator panel 1
By installing 03, the contents scanned by ITV camera 101 or line sensor 105 can be transmitted to operator panel 10 without installing 0CR44.
3 on the monitor, and based on the contents displayed on the monitor, the journal number of the package can be input into the control system through the operator panel 103. In these embodiments, the tag is generally attached to the top of the package;
This was done in consideration of the fact that they are rarely pasted on the sides and that OCR is relatively expensive. Note that when the ITV camera 101 images the side of the package, the package may be automatically rejected from the main conveyor 9 and put on hold temporarily, or one of the multiple main conveyors 9 may be set to a conveyor exclusively for rejects. It is preferable to make the monitor display easier to see and to make it easier to supply rejected packages to the peripheral conveyor 15 by doing this. With this configuration, only one staff member is required for each of the main conveyors 9, and the staff member only has to key in the journal number for the parcels for which the journal number could not be recognized in 0CR43, reducing the burden on the staff member. It is significantly reduced, and night work becomes reliable and efficient. In addition, in the example, two types of light emitting laser sources were used, but one
A similar effect may be achieved using separate laser sources that emit red and green or blue wavelengths at the same time. In addition, in the embodiment, the tag 31 is used as shown in FIG. 2, but instead of using this tag 31,
It is also possible to use a paper consisting of only the journal number entry column "" by pasting it on the old tag.
Even if a package whose journal information is given by the form on which the journal information is written is arbitrarily fed to a certain position in one of two different states, the journal information of the baggage can be read quickly and accurately at that fixed position. In addition, it is possible to sort packages according to the read journal information. 4.
