Further, the electronic control circuit 60 controls each sorting machine W4]a, 1
One electronic control circuit is provided for each of the electronic control circuits 60, b, . And the host computer 75
(Secondly, the keyboard 74 allows the order in which each transport body 36 is to be transported to each work station ST1, etc. to be determined for each transport body 36 according to the work process of sewing products etc. Then, the host computer 7
5 outputs to each electronic control circuit 60, for each carrier 36, a destination instruction indicating to which work station STI, . . . the carrier 36 should go next. Destination instructions from the host computer 75 are stored in each electronic control circuit 60 (table) as shown in the destination instruction table 76 shown in FIG. The destination instructions for each 36 may be stored in the electronic control circuit 60 respectively.The destination instruction for each destination 36 may be stored in the electronic control circuit 60. When a signal is received,
The work station STI to which the carrier 36 should go next
, . . . are output to each electronic control circuit 60, and the destination instruction table 76 is rewritten.

Next, the process carried out in the electronic control circuit 60 described above will be explained with reference to the flowchart shown in FIG. 10.

First, when the chain drive motor 26 provided in the sorting machine 1111a is rotated, the first chain 20 is moved through the drive pulley 28, timing belt 30, etc., as shown in FIGS. 4 and 5. The second chain 23 is moved counterclockwise in FIG. It is moved around in the same direction along the rail 11.

Thereby, the carrier 36 on the bridge rail 8.10 or the station rail 11 (with the upper architrave 38 engaged with the first or second chain 2o, 23, the bridge rail 8, ]O or the station rail 11 It is conveyed and moved in the direction of the arrow in FIG. 2 along the arrow.

Then, the carrier 36 is transported along the bridge rail 8 to a position corresponding to the number reading device 39, and this carrier 36
The movement of is temporarily stopped by a stopper (not shown). At this time, it is determined whether or not there is a conveyance body 36 to be carried into the sorting mechanism]a based on whether or not the number reading device 39 reads the conveyance body identification number attached to the conveyance body 36. Once determined, the following distribution control process is executed (step 100, hereinafter simply 5100).
Expressed as Same below. ). Next, for each sorting arm 44, the presence or absence of a carrier 36 to be carried into that sorting arm 44 is stored (S110).

In this embodiment, each sorting arm 44 is assigned an arm number 1 to 8 to distinguish each other, and the carrier 36 of which number is carried into the carrying-in portions 8a and 11a located opposite to the sorting arm 44 of a certain arm number. The number reading device 39 reads the number and stores the presence "1" and the absence rQJ as shown in the conveyor distribution table 78 shown in FIG. 12.In this embodiment, there are four loading sections 8a and lla. Therefore, the carrier 3
6 may be brought in at the same time.

Next, referring to the destination instruction table 76 in FIG.
It is determined whether there is a destination instruction of No. 6 (S120).

In this embodiment, the destination instruction is given as a station number (a number other than O), and the destination instruction table 76 contains "
If there is a number other than "0", there is a destination instruction, and "
0'' is a case where there is no destination instruction, which will be described later.

Then, when there is a destination instruction (with reference to the destination instruction table 76), how many times should the distribution arm 44 be rotated in order to distribute it to the bridge rail 10 or station rail 11 according to the destination instruction? Then, as shown in the carrier distribution table 78 in FIG. 12], the rotation angle and destination rail number are stored for each distribution arm 44, and a distribution command is set ( S130).

If there is a plurality of distribution arms 44 stored as having transport bodies 36 in S]]O, the above-mentioned 8120
By repeating the following process, the distribution arm 4
The rotation angle and destination rail number are memorized every four times, and a distribution command is set (S140).

After storing the necessary distribution commands in the transport body distribution table 781 in this manner, the stopper is retracted to release the stop of the transport body 36, and as shown in FIG.
The arm 4 distributes the conveyor 36 from the loading sections 8a and 11a.
4 (S150). Then, the tag carrier 36 descends under its own weight to the position where it engages with the engagement protrusion 45a on the downwardly inclined 45, and the engagement shaft 38 disengages from the first or second chain 20.23. is held stationary on the holding wheel 45.

In this state, based on the contents of the carrier sorting table 78, the servo motor 47 for arm rotation is rotated by a predetermined angle, and the rotary body 4 is rotated in the forward or reverse direction via the drive pulley 48, etc. The sorting arm 44 holding the carrier 36 is rotated to a position facing the carrying-out sections 10b and llb (S160).

After the rotation arrangement is completed, the pushing up body 53 is raised by the pushing up cylinder 51 corresponding to the twisting arm 44 holding the conveying body 36, and the holding rail 45 is rotated from a downwardly inclined state to a horizontal state and conveyed. The body 36 is raised and the engagement shaft 38 is engaged with the first or second chain 20.23.

Then, as the first or second chain 20.23 moves, the conveyor 36 is transferred from the distributing arm 44 to the unloading section 10b.
,] 1b (S170).

In the case where the processes 5160 and 5170 are shown in the conveyor distribution table 78, 1 for each distribution arm 44:
, repeats 4 times to unload all the transport bodies 36 (S18
0), after all the carriers 36 are unloaded, the process returns to 5100 and the following process is repeated.

Note that when the transport body 36 reaches a position corresponding to the work stations STI, . A worker such as a sewing manufacturer removes an article such as a sewn product from the conveyor 36 in this state, performs sewing or other work on the article, and returns the article to the conveyor 36, after which the stopper After being evacuated, the transport of the transport body 36 is resumed.

At this time, in this embodiment, when the (friend sorting mechanism) a transports the carrier 36 onto the station rail 11 to the work station ST, the destination instruction table 7
As shown in 6, the destination instruction corresponding to the carrier 36 is set to "0".

That is, the work station ST located below the station rail 11 connected to the distribution mechanism 1a]
Only when distributing the conveyance body 36 with the conveyance body number 36-3 whose destination is the work station STI, after the distribution is completed, the destination instruction of the conveyance body number 36-3 in the destination instruction table 76 of the distribution mechanism 1a is sent. rQJ
Make it.

This is because when the work at work station STI is completed and the transport body 36 returns to the sorting mechanism]a, if the destination instruction remains as station number rsTIJ, it may be transported to work station STI again. This is to prevent this.

When the predetermined work on the carrier 36 with the carrier number 36-3 is completed at the work station ST1, a completion signal is issued to the host computer 75. Then, the host computer 75 instructs the next destination work station ST2, . . . of the carrier 36 with the other carrier number 36-3. For example, due to the work progress status of 1'L, the work at the next destination work station ST2, ... is delayed, and the delayed work station ST2, ... is the next destination of the conveyor. There are many 36, work station ST2,...
・It may get stuck in some cases. Also, before transporting the carrier 36 with the carrier number 36-3 to the destination work station ST2, . 36 may need to be brought in first. In such a case, the host computer 75 does not instruct the electronic control circuit 60 to instruct the next destination of the carrier 36 with carrier number 36-3 until the above-mentioned condition is resolved. In such a case, the carrier 3 with carrier number 36-3
6 (until the above-mentioned condition is resolved, the destination instruction table 76 has a destination instruction of "0", which means that the conveyance body 36 has no destination instruction).

As mentioned above, if there is no destination instruction for the carrier 36, it is determined whether the carrier 36 was transported by the station rail] 1 (5190), and if it is the station rail 11, the carrier 36 is 36, the specific bridge rail 1 defined for each station rail 1]
Calculate the rotation angle of how many times the distribution arm 44 of which number should be rotated so that the distribution arm 44 can be distributed to 0, and set the distribution command by storing the rotation angle and destination rail number for each distribution arm 44. (S 200). This station rail]] Specific bridge rail 1 determined for each
For example, in this embodiment, o is the station rail]]
The bridge rail 10 closest to the unloading section]]b is set as the bridge rail 10, and a different bridge rail 10 may be determined for each station rail 11.

On the other hand, when the station rail 11 is not the station rail 11, for example (the melon transporter 36 is the neighboring sorting mechanism), from b to the bridge rail 8
How many times should the distribution arm 44 of which number be rotated so that the home conveyor 36 is distributed to the bridge rail 1o connected to the adjacent distribution@ellipse 1b? The angle is calculated, and the rotation angle and destination rail number are stored in correspondence with the distribution arm 44 to set a distribution command (S210). Thereafter, the processes 5150-3180 are performed as described above, and the carrier 36 is transported out.

Note that the number reading device 39 works as a number reading means M],
Sorting mechanisms 1a, 7b, ..., and 5150-S]
The process 80 works as the distribution means M2. Also, 51
20 acts as destination determination means M3, and 5130
The execution of the process acts as the normal setting means M4, and the process 514
Execution of processes 0 to 5160 functions as return setting means M5.

As mentioned above, the conveyance device of the present invention (upper number reading device 3
Based on the number of the conveyance body 36 read by 9, it is determined whether or not there is a destination instruction for the conveyance body 36 carried into the sorting mechanism 1a. Then, when there is a destination instruction, a distribution instruction is set according to the one-friend destination instruction. In addition, when there is no destination instruction, it is determined whether the conveyance object 36 was conveyed by the station rail 1, and when the conveyance body 36 is conveyed from the station rail 11, the When the bridge rail 8 is transported via the bridge rail 8, the bridge rail 101 connected to the bridge rail 101 connected to b is set to Sorting instructions are set, and the carrier 36 is conveyed according to these distribution instructions.

When a conveyor 36 without a destination instruction is conveyed,
If the conveyance of the conveyance body 36 is stopped until the next destination instruction is received from the host computer 75, other conveyance bodies 36 that are conveyed one after another will be stuck by the conveyance body 36 for which no destination instruction is given. Therefore, the flow of the conveyor 36 becomes congested and the processing time becomes longer.

As mentioned above, the bridge rail 101 connects the conveyor 36 without a destination instruction to another sorting mechanism 1b: By sorting, the flow is not congested, the processing time is shortened, and the work efficiency is improved. be able to.
