Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport sorting apparatus for collecting a delivery such as a catalog book and a small delivery such as a reply postcard or a booklet.

[0002]

Conventionally, as a transporting apparatus for collecting pamphlets and the like as main deliverables and collecting individual deliverables such as forms on them, for example, Japanese Patent Application Laid-Open No. Hei 8-5906
As shown in Japanese Unexamined Patent Publication No. 1 (1993), a sub-transport line is merged with a main transport line for sequentially sending out the main deliverables, and the main transport line is connected to the deliveries moving on the main transport line. There has been proposed a system in which deliveries such as forms are sequentially stacked from a sub-transport line synchronized with a transport timing. In this way, the main transport line and the sub-transport line are merged, and the delivery items can be sequentially grouped, so in the shipping business of sending a plurality of relatively large main delivery items such as catalog books together, For each set of the main deliverables, it has been demanded to combine deliveries such as postcards and booklets that are further grouped into a plurality of divided states.

However, the main transport line for transporting relatively large deliverables and the small deliveries such as postcards are divided into one or more sets of unspecified numbers, and the main transport line The following problems have arisen when combining with the sub-conveying line for sending to the sub-line. First, the main transport line has a plurality of sorting pockets which sequentially move in an aligned state, and a plurality of supply units are arranged along a moving direction of the sorting pockets. While the pocket is moving, one or more main deliveries from one or more of the supply units (in the case of a plurality, the main deliveries may be the same or different as required). To accept. And while the mechanism of the supply unit and the transport mechanism of the sorting pocket become relatively large,
Since the final end of the line has reached the packing process, etc., the operating status of this main transport line greatly affects the operating status of the entire transport sorting device, and therefore, the transport speed on this main transport line is kept as constant as possible. It is necessary to do so. On the other hand, in the sub-transport line, the delivery items such as postcards and pamphlets are supplied so as to be placed on the main delivery items placed in the sorting pockets of the main transport line. A set of deliverables is put together and sent out sequentially to the main transport line side. Then, the delivery items (postcards, pamphlets, etc.) are not set one by one, but randomly, that is, three sets for one sorting pocket and 10 sets for another sorting pocket in accordance with each sorting pocket of the main transport line. In the case where supply is made for each divided pocket by the number of sets set according to the order of sending the main delivery, such as a set, the required number of sets of deliveries sequentially sent from the supply unit side of the sub-transport line arrive. And then the sorting pocket is sent out, so that the supply tempo at the end of the sub-transport line fluctuates greatly. However, as described above, it is necessary to maintain the transport speed of the main transport line as constant as possible, and it is necessary to maintain the transport speed of other supply units (supply units in the main transport line) or the transport mechanism of the sorting pocket. The transport speed cannot be changed in an analog manner due to restrictions, so the combination of a sub-transport line whose supply tempo at the end greatly changes and a main transport line that wants to maintain a constant transport speed is It was difficult. Therefore, in view of the above circumstances, the present invention provides a storage portion of the delivery on the sub-transport line so that the supply tempo at the end of the sub-transport line can be kept constant, and steps in accordance with the storage amount in the storage portion. The problem is to change the transfer speed of the main transfer line, and to make it possible to efficiently carry out a delivery operation that combines a relatively large main delivery item such as a catalog book with a delivery item such as a postcard. Aim.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail based on an embodiment shown in FIGS. FIG. 1 shows a transport sorting apparatus 1 according to the present invention. The transport sorting apparatus 1 includes a main transport line 2 and a sub-transport line 3 which joins the main transport line 2. The main transport line 2 has a plurality of sorting pockets 4 that move sequentially 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 supplied from the supply unit 5 based on information set in advance according to the delivery order of the delivery items.
Are sent out to the sorting pocket 4. That is, each of the sorting pockets 4 does not always send out the main delivery from all the supply units 5 at the time of its movement, and the type and number of the main delivery to be sent into each sorting pocket 5 are the same although there is an upper limit. There is a case where it is different or a case where it is different, and supply of such a main delivery to each sorting pocket is provided so as to be performed based on preset information. In the main transport line 2, after the deliveries 7 from the sub transport line 3 are placed on the main deliveries 6 in the respective sorting pockets, the main deliveries entering the sorting pockets 4 in the packaging process 8. And the delivery are packaged together, and the main delivery and the combined delivery are collected and sent from the end side through the form supply step 9 to the packing step.

[0006] The sub-transport line 3 includes a sub-supply unit 10 that divides the delivery 7 sent from the supply source in a continuous state or the like and supplies it in required units and a sub-supply unit 11 that sequentially supplies booklets and the like. Further, a packaging section 12 is provided for packaging the delivery items sent from the sub-supply sections 10 and 11 for each set. Note that the delivery items sent from the sub-supply units 10 and 11 may have the same type or number of the delivery items, or may differ from each other. Based on the set information, it is assumed that the main delivery is associated with the main delivery carried in the sorting pocket 4 of the main delivery line. Then, on the sub-transport line 3, the individually bundled deliveries 7 are sent out to the buffer unit 13, and sent out from the buffer unit 13 to the main transfer line 2. In the illustrated example, the sub-transport lines 3 are provided in two rows, and the main delivery 6 in one sorting pocket 4 is provided.
The delivery items 7 are provided so that the delivery items 7 can be placed in two rows as needed, but the delivery items are supplied from both sub delivery lines 3 in order to flatten the top shape in the package. Is good.

In the sub-transport line 3, when delivering a delivery from the end side to the sorting pocket 4 of the main delivery line 2, each delivery 7 is associated with the main delivery 6 as described above. , And one or a plurality of sets of deliveries 7 are sent out in an accumulated state. The supply of a random number corresponding to the delivery 6 is performed by the buffer unit 13. FIG. 2 shows a buffer unit 13, an annular band 15 having a large number of receiving units 14 for holding the delivery 7 connected thereto, a driving source 16 for moving the annular band in one direction, and a receiving unit for the annular band. And a supply table 17 for sending out the delivery held by the section to the end of the line by moving forward and backward. The receiving portion 14 of the annular band 15 that rotates in one direction on the receiving side of the delivery.
The delivery 7 is sent to each of them, and the length of the delivery 7 to the supply table 17 is a portion for storing the delivery. When the annular band 15 moves downward on the supply table 17 side, the receiving portion 14 holding the set of deliverables corresponding to the main deliverables is supplied to the supply table 17. When the table 17 is sent out, the set of deliveries is locked on the supply table 17 and stands by so as to fall out of the receiving portion 14. In this way, a required number of sets of deliveries are sent out from the storage end while a certain amount of storage is secured, so that the supply tempo is almost constant from the end 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 for supporting the belt so as to be able to move up and down. Part 1
4 so that the number of receiving portions for receiving the delivery is changed, that is, the amount of storage of the delivery is variable.

The main transport line 2 is provided with a buffer amount detector 19 for detecting two types of accumulation stages, large and small, based on a predetermined accumulation amount in the buffer unit. The main transport drive unit 20 that moves the sorting pocket at two different transport speeds, a speed and a second transport speed slower than the first transport speed, and controls the main transport drive unit based on a detection signal from the buffer amount detection unit. A control unit 21 is provided. As shown in FIG. 3, the operation of the buffer amount detecting section 19 outputs information for starting the main transport line at the first transport speed after the buffer amount exceeds 40 divided pockets as an initial setting (A), for example. The accumulated amount of the delivery is monitored and detected (B). Then, when the accumulated amount becomes equal to or less than 20 sorting pockets, information for setting the second transport speed is issued (C). The accumulated amount at the second transport speed is monitored and detected (D), and when the accumulated amount becomes equal to or more than 40 sorting pockets, information about the first transport speed is output (E). And
It will be monitored whether the sorting process is continued. In this way, based on the information sent from the buffer amount detecting section 19 according to the accumulation amount in the buffer section 13, the main transport driving section 20 moves the main transport line 2 to one of the first transport speed and the second transport speed. The main transport drive unit 20 is controlled under the control of the control unit 21 which receives a detection signal of the buffer amount detection unit. The number of storage stages monitored and detected by the buffer amount detection unit may be three or more. Further, in the present invention, the transport speed of the main transport line is not limited to only two stages of the first transport speed and the second transport speed.
