BACKGROUND OF THE INVENTION
The present invention relates to a conveyance sorting apparatus that collects a plurality of information sheets and packages them for each group.
[0002]
[Problems to be solved by the invention]
Conventionally, for example, Japanese Patent Application Laid-Open No. Hei 8-59061 discloses a conveying apparatus that collects information sheets on which delivery destination information such as a form is printed as a main information sheet to be delivered to a delivery destination. As shown in the figure, sub-transport lines are joined to the main transport line that sequentially sends out the main delivery items (information sheets), and the transport timing of the main transport line for the deliveries moving on the main transport line. It has been proposed to supply delivery items as information sheets (invoices, guides, invoices, etc. corresponding to individual delivery destinations) that are printed in order from a sub-conveying line synchronized with Yes.
In this way, it is now possible to combine the main transport line and the sub-transport line so that the deliverables can be gathered sequentially, so that a plurality of main deliveries of relatively large information sheets such as catalog books can be gathered together. In the shipping business to be dispatched, it seems that it is desired to match a plurality of deliverables (the above-mentioned invoices, invoices, etc.) collected in a plurality of separate states for each main delivery set. It has become.
[0003]
However, the main transport line that transports relatively large deliveries and the sub transport that separates small and thin deliveries into one or more unspecified numbers and sends them to the main transport line. The following problems occurred when combining with the line.
First, the main transport line has a plurality of sorting pockets that are sequentially moved in an aligned state, and a plurality of supply sections are arranged along the moving direction of the sorting pockets. One or more main deliverables from one or more of the supply units while the pocket is moving (in the case of plural, the main deliverables may be the same or different as necessary) To accept. And the mechanism of the supply section and the transport mechanism of the sorting pocket are relatively large, and since the final end of the line has reached the packing process etc., the operating state of this main transport line is the whole transport sorting device. Therefore, it is necessary to keep the transport speed in the main transport line as constant as possible.
On the other hand, in the sub-conveyance line, the delivery item (information sheet) on which the delivery destination information is printed is supplied so as to be placed on the main delivery item placed in the division pocket of the main conveyance line. A set of deliverables is collected and sequentially sent to the main transport line side. Then, according to each sorting pocket of the main transport line, the delivery items are randomly delivered instead of one by one, that is, 3 sets for a certain sorting pocket and 10 sets for another sorting pocket. When supplying each set of pockets according to the number of sets set according to the order of delivery, wait until the required number of sets of deliveries sent sequentially from the supply section of the sub transport line arrive. Therefore, the supply tempo on the terminal end side of the sub-conveying line greatly fluctuates. However, as described above, it is necessary to keep the conveyance speed as constant as possible in the main conveyance line, and mechanical parts such as another supply unit (a supply unit in the main conveyance line) and a sorting pocket conveyance mechanism. The transfer speed cannot be changed in an analog manner due to restrictions, etc.Therefore, the combination of the sub transfer line whose supply tempo at the end changes greatly and the main transfer line that wants to maintain a constant transfer speed is It was difficult.
[0004]
From this point of view, the applicant of the present invention provides a buffer unit in the sub-conveying line, and sends out a set number of deliverables corresponding to the main delivery item from the buffer unit to the main carrying line side for each set. A transport sorting device was proposed. In addition, there is a possibility that some combination error may occur in various sheets conveyed by the conveyance sorting device, and it is necessary to deal with them. Therefore, in the present invention, the configuration of the delivery is made appropriate. Is an issue.

DETAILED DESCRIPTION OF THE INVENTION
Next, the present invention will be described in detail based on the embodiment shown in FIGS.
FIG. 1 shows a transport sorting apparatus 1 according to the present invention. The transport sorting apparatus 1 includes a transport line composed of a main transport line 2 and a sub transport line 3 joined thereto. The main transport line 2 has a plurality of sorting pockets 4 that are sequentially moved in an aligned state, and a plurality of supply units 5 are arranged along the moving direction of the sorting pockets 4. The main delivery item 6 is sent out from the supply unit 5 to the sorting pocket 4 based on information set in advance according to the delivery order of the delivery items. That is, each of the sorting pockets 4 does not necessarily send out the main delivery items from all the supply units 5 at the time of movement, and the types and number of the main delivery items to be sent into each sorting pocket 4 are the same although there is an upper limit. There are cases where there are cases where there are cases where the main delivery items are distributed to the respective sorting pockets. In the main transport line 2, after the delivery 7 from the sub transport line 3 is placed on the main delivery 6 in each sorting pocket, the main delivery in the sorting pocket 4 in the packaging unit 8. The package is bundled and delivered from the terminal side through the form attachment part 9 and the rejection part 24 for sending out the form 23 to each individual package and sending it to the packaging process. ing.
[0007]
The sub-conveying line 3 includes a supply unit 10 that supplies a required unit by dividing a delivery 7 sent out from a supply source in a continuous state, a supply unit 11 that sequentially supplies a booklet, and the supply unit 10. , 11 is provided with a wrapping section 12 for wrapping the delivered items for each set. The delivery items sent from the supply units 10 and 11 may be the same or different in the type and number of the delivery items. The types and number of the delivery items may be set in advance. Based on the information thus obtained, the main delivery line is associated with the main delivery item to be conveyed in the sorting pocket 4.
Then, in the sub-conveying line 3, individually delivered items 7 are sent out to the buffer unit 13 and are sent out from the buffer unit 13 to the main conveying line 2. In the illustrated example, the sub-conveying lines 3 are provided in two rows, and the delivery items 7 can be placed in two rows on the main delivery item 6 in one sorting pocket 4 as necessary. However, in order to flatten the upper surface shape in the packaging form, it is preferable to supply the delivery items from both the sub delivery lines 3.
[0008]
In the sub-conveying line 3, when the delivery is sent from the terminal side to the sorting pocket 4 of the main transportation line 2, each of the delivery items 7 is associated with the main delivery item 6 as described above. Then, a plurality of sets of deliverables 7 are sent out in an accumulated state. The buffer unit 13 supplies a random number corresponding to the main delivery item 6.
FIG. 2 shows the buffer unit 13, an annular band 15 provided with a number of receiving parts 14 for holding the delivery 7, a drive source 16 for moving the annular band in one direction, and the receiving of the annular band. And a supply table 17 for sending the delivery held in the section to the line end side by advancing and retreating. Then, the delivery 7 is sent to each receiving part 14 of the annular band 15 that rotates and moves in one direction on the delivery side of the delivery, and the length until reaching the supply table 17 accumulates the delivery. It is a part to do. On the supply table 17 side, when the annular band 15 moves downward, the receiving unit 14 holding a set number of deliveries corresponding to the main delivery is supplied to the supply table 17. When the table 17 is moved out, the delivery table 17 is held on the supply table 17 so that the delivery items are locked and come out of the receiving portion 14. In this way, since a necessary number of deliveries are sent out from the storage end side in a state where a certain amount of storage is ensured, the supply tempo is almost constant from the end side of the sub transport line 3. Become. Further, in the buffer section 13, the annular band 15 is provided with a plurality of rollers 18 that support it so that it can be moved up and down. It can be stored in the unit 14, and the number of receiving parts for receiving the delivery is changed, that is, the storage amount of the delivery is variable.
[0009]
The main transport line 2 is provided with a buffer amount detection unit 19 that detects two types of accumulation stages, which are large and small, based on the predetermined accumulation amount in the buffer unit, and the first conveyance speed and this A main transport drive unit 20 that moves the sorting pocket at two transport speeds, a second transport speed that is slower than the first transport speed, and a control unit 21 that controls the main transport drive unit based on detection signals from the buffer amount detection unit. Is provided. In this way, based on the information sent from the buffer amount detection unit 19 according to the accumulation amount in the buffer unit 13, the main transport driving unit 20 moves the main transport line 2 through the first transport speed or the second transport speed. The main transport drive unit 20 is controlled under the control of the control unit 21 that receives the detection signal of the buffer amount detection unit.
[0010]
FIG. 3 shows a delivery state at each supply unit in the main transport line 2 and the sub transport line 3. In the main delivery items and sub-delivery items sent out from the supply unit, all or some of them are constituted by an information sheet 26 preprinted with identification information 25 that can be machine-readable. In the supply unit for sending out the information sheet 26 having the identification information 25, a sensor 27 for reading the identification information 25 is provided as shown in FIG. 3, and the identification read by the sensor 27 is provided. Information is sent to the collation device 28. The sensor 27 may be installed on the transport line instead of being installed in the supply unit, and may be configured to read the identification information on the main delivery item to be transferred and the information sheet in the delivery item.
The collation device 28 collates whether or not the combination of information sheets set according to the preset feeding order is appropriate. That is, a combination of information sheets constituting the main delivery item, a combination of information sheets constituting the delivery item, a combination of the main delivery items to be collected and a combination of the delivery items to be collected, and these Also check the combination of the combinations. In addition, the package 22 delivered via the packaging unit 8 may be grouped and transported for each same delivery destination, and the arrangement of delivered items before and after the moving sorting pocket is also checked.
[0011]
In this way, the collation device 28 always sends the collation result to the control unit 29. The control unit 29 causes the reject unit 24 to take out the package when the collation in the collation device does not match, and the rejected unit 24 performs the main transport of the package that has not been matched by the reject unit 24 after the form attachment unit 9. The package that has been discharged from the line 2 (see FIG. 1) and made appropriate is sent out from the end of the main conveyance line to the next process.
