Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a control device for a network-like transport line that transports a transport body to a predetermined transport destination on a predetermined transport line.

[Prior Art] Conventionally, as a control device for a network-like conveyance line, there is a technique (disclosed in Tomo-Tokuko No. 59-28495). It comprises a path T and a branching means B for branching the carrier conveyed on the transfer path T to a predetermined transfer path,
A loop-like ordinal number (0, 1, 2...) on the transfer path T
5), the conveyor is conveyed to a desired transfer path T. That is, each branching means 8 located at a branch point of each transfer path T stores the ordinal numbers attached to all the transfer paths T in a loop shape, and the stored ordinal numbers and the ordinal numbers attached to the conveyor are stored. The destination number is compared with the destination number, and the transport object is branched to the transport path T that matches the destination number.

[Problem to be solved by the invention] However, in the conventional technology (the direction of the companion conveyor is
Since the configuration was such that judgment was made based on the ordinal number 1 attached to the transfer path T in a loop shape, there was a problem that it was difficult to change the network shape of the transfer path or expand the transfer path T. Since each transfer route 1 in the network shape is not specified by the ordinal number assigned to the shape, the eighth
As shown by the dotted line in the figure, the arrangement of the transfer path T can be changed,
Or, if you add (friend), the order number from the added transport path T onwards will be changed to sequential, as shown by "()" in Figure 8.For this reason, most branches The present invention had the problem that the program data of Means B had to be modified in response to this change (by solving the above problems, it is possible to easily rearrange and expand the networked conveyance line. The purpose of this invention is to provide a control device for a networked conveyance line.

[Means for Solving the Problems] As a means for achieving the above object, a control device for a network-like conveyance line according to the present invention includes a 1-mm conveyance rail and a device conveyed on the conveyance rail, as illustrated in FIG. 1 conveyor
, or a communication conveyance rail that connects one conveyance line and another conveyance line among the plurality of conveyance lines, in which a plurality of conveyance lines are arranged in which branching means that branch to a plurality of predetermined conveyance destinations are alternately connected. A control device for a network-like conveyance line arranged between the branching means (herein, destination identification means for identifying the destination of the conveyance body and the destination conveyance line to which the destination belongs; It is configured based on the conveyance destination and arrival conveyance line, and the identification symbol provided for each of the above-mentioned branching means and each conveyance line. The gist of the present invention is to include branching direction determining means for determining the branching direction of the transport body by the branching means.

[Operation] The branching direction determining means of the control device for a networked conveyance line of the present invention compares the destination of the conveyance body identified by the destination identification means and the destination conveyance line to which the destination belongs with branch data. Then, the direction in which the conveyance body is branched by the branching means is determined. Thereby, the branching direction of the transport body in each branching means is determined based on the identification symbol provided for each branching means and each transport line.

For example, throughout the network-like conveyance line,
At the conveyance destination (for example, a processing station) and the conveyance line,
Number them in ascending/descending order and use this number as an identification symbol. Then, branch data is set for each branching means based on the identification symbol. This branching data (the number of the destination directly connected to the branching means, the number of the conveyance line to which it belongs,
It is composed of other transport destinations and other transport line vertical directions. In this way, branch data is set for each branching means, and this data is compared with the transport destination of the transport body and the number of the reached transport line, and it is determined whether the results of the comparison match, are larger, or smaller. Judgment is made to determine the branch destination of the carrier.

Therefore, according to the present invention, the whole can be identified by identification symbols in ascending and descending order instead of looped numbers. As a result, as shown by the dotted line in Figure 8, when transport rails and transport destinations are added to the end of the network (branch means to which the added transport rails and transport destinations are connected (symbol f in the figure)

When the push-up body 63 is lifted by the push-up cylinder 61, the rotating arm 55 supporting the hanger 46 is rotated from the downwardly inclined state to the horizontal state, and the hanger 46 is moved to the first chain 30 or to the first chain (not shown). 2 chain.

In addition, regarding the mechanical configuration 1 of the hanger conveyor line 1,
Since it is described in Japanese Patent Application No. 1-193129 and Japanese Patent Application No. 1-196362 pending by the present applicant, further detailed explanation will be omitted.

Control circuit 7 (as shown in Table 5, hanger detection device 49, detector 67 and 2 communication interface 72,
It is connected to the encoder 74, the solenoid group 73, and the servo motor 57. The detector 57 detects the position of the arm 54 for the distribution. The hanger detection device 49 (Y) is connected to each control circuit 7 as many times as the number of branches managed by each control circuit 7.The communication interface 72 is used to input processing data to be executed by the control circuit 7 from the command device 8. The encoder 74 is used for the servo motor 5.
The amount of rotation of the servo motor 57, that is, the rotation angle of the arm 57 is detected. The control circuit 7 includes various memories (not shown) such as a program memory, and outputs predetermined command signals based on inputs from the hanger detection device 49, the detector 67, the communication interface 72, the encoder 74, and the like. The servo motor 57 rotates in response, causing the free end of the arm 54 to be positioned opposite the end of the predetermined intermediate rail 20 or distribution rail 2. Further, in response to the output from the control circuit 7, the solenoid group 73 of the electromagnetic valve manifold (not shown) is selectively activated, and the predetermined push-up cylinder 6 is activated or exhausted, and the push-up member 63 is activated. is moved up and down.

Command device 8 [i] Consists of a keyboard 8a and a command circuit 8b. The command circuit 8b has an input/output interface (not shown). This input/output interface 1
Friend is connected to the communication interface 72 of each control circuit 7. Keyboard 8 a It.

It is used to input data to the command circuit 8b and to input predetermined control data to each control circuit 7 via the command circuit 8b2 communication interface 72. Command circuit 8b (
1. It has a microcomputer and executes predetermined processing.

Next, the operation of the hanger conveyor line 1 configured as described above will be explained based on the flowchart of the branching process shown in FIG. 6 and FIG. 7 shown for explaining this operation. The branching process in FIG. 6 (shows the process executed in the companion control circuit 7Aa). Similar processes are executed in other control circuits 7 as well.

In the hanger conveyor line 1 of this embodiment, each hanger is distributed by a chain drive motor 3 provided in the device 5.
6 is rotated, the first chain 30 moves to the intermediate rail 20
3 in the counterclockwise direction in FIG. 3, and a second chain (not shown) is moved in the same direction along the distribution rule 21.

Thereby, a hanger 46 for suspending articles supported on the intermediate rail 20 or the distribution rail 21
is transported in the direction of the arrow in FIG. 3 along the intermediate rail 20 or the distribution rail 21 while being engaged with the first chain 30 or the second chain. When the hanger 46 is transported to a position corresponding to the hanger detection device 49, a stopper (not shown) is thrust onto the moving path of the hanger 46 and the movement of the hanger 46 is temporarily stopped.
The hanger detection device 49 reads the code mark for identifying the hanger attached to the hanger 46 and recognizes the ha number (S10). Then, based on this identification number, the control circuit 7 determines whether or not the destination of the hanger 46 has been instructed (S20).
The destination number is determined based on an identification number-destination number comparison table as shown in Table 1 below, which is input in advance into the program memory in the control circuit 7Aa.

Table 1 Identification number-destination number comparison table referred to herein Table 1 records the line numbers and station numbers of destination processing stations PS to which predetermined hangers 46 are sequentially transported in order of withdrawal.

When a predetermined hanger 46 reaches the processing station PS with the destination number, the line number and station number are changed to the destination line and station number of the next processing station PS based on the command from the command device 8. Ru.

For example, when the hanger 46 with E lit number 1 arrives at line number rlOJ and station number "20" shown in the first place in Table 1, the next destination processing station PS is line number r20J and station number "30". " is set.

If the destination of the hanger 46 is specified (Next, it is determined whether the destination line number and the current line number are the same (S30).This determination is made based on the line number of the destination of the hanger 46 and the following As shown in Table 2, the hanger allocation is done depending on whether the line numbers individually set in the device 5 are the same or not. First line 1A on one end side
They are set in ascending order from C to the third line on the other end side. For example, the f-distribution is set in the device 5Aa (as shown in Figure 7), and the line number "10" is set. Also, in Table 2, the station number is has been done.

Table 2 Station number (Processing station PSAaa, PSBaa on one end side of friend hanger conveyor line 1, or Processing station PSAeb on the other end side from PSCaa,
They are set in ascending order toward PSBfb or PSCdb. For example, the station numbers "30" and "4o" are set on the device 5Aal:I as shown in FIG.

1st. Second. Mutual values of station numbers in the third lines IA, 1B, and IC (as shown in Table 2 above and Figures 2 and 7, the hanger distribution directly communicated by the communication hanger rail 3 is based on the device 5. In addition, even if station numbers are assigned, the distribution shown in FIG. 7 indicates that the corresponding processing station PS is It may not exist.

In the judgment at S30, if the destination line number and the current line number are the same (here, the friend destination and current line number are both "]0"), then (
Next, it is determined whether the destination station number a and the current location station number are the same (S40). Destination station number a (This is the value calculated by referring to Table 1 based on the identification number.For example, as shown in Figure 7, if the destination line number is "10" and the destination station number Suppose that is "30".

In the judgment at S40, the destination station number a(r3
0J) and multiple station numbers b (r30
”, r4(g) (in this case, “30” corresponds), then the processing station PS corresponding to the station number “30” (in this case, processing station PSAaa) (S50).The hanger 46 is placed in a predetermined processing station PS (step S50).The hanger 46 is placed in a predetermined processing station PS (step S50). This is done by sequentially branching out to branch rails 9 that connect to predetermined processing stations PS.

When the hanger 46 reaches the destination processing station PS, the control circuit 7Aa then sends the command device 8 through a process (not shown) to send the specified hanger 46 to the destination processing station P.
A signal indicating that S has been reached is output. This causes the command device 8 (and each control circuit 7 to set the designated hanger 4).
Outputs a signal to advance the destination number 6 by one. Illustration
Line number "]O" is changed to "20" Station number "30J" is changed to "30". In this state, the sewing worker removes an article such as a sewn product from the hanger 46, performs sewing or other operations on the article, and then returns the article to the hanger 46, and the conveyance of the hanger 46 is resumed. Ru.

In S40, if it is determined that the destination station number a and the station number of the current location are not the same (for example, if the destination station number a is not "30" or "40"), then the destination station number a It is determined whether or not the station number of the current location is greater than the station number of the current location (S60). Here, if a>b, then the hanger 46 is sent to the side where the station number increases (S70).In other words, since the station numbers at the current location are r30J and r404, the station For distributions for which the number is set to a value larger than "40", the process of sending the hanger 46 to the hanger rail 31 directly connected to the device 5 is executed by a drive process (not shown). The allocation for which rsoJ and r60J are set is sent to Hungerail 3Aa which is directly connected to device 5Ab.

On the other hand, in S60, if it is determined that the destination station number a is not larger than the current location station number b (r30J, r40") (for example, when a is set to "10"), The process of sending the station number to the side where the station number decreases is executed (S8
0). In addition, the hanger distribution of 1st line A is device 5A.
As shown in FIG. 7, in a, the processing station PS is not provided on the side where the station number decreases (the left side in the figure), so this process is not activated here. Also, if the hanger conveyor line 1 is expanded at a later date, the distribution will be made to the side where the station number in the device 5Aa decreases (as shown by the dotted line in Fig. 7, if the processing station PS is added, will be carried out.

The process of 540-S80 described above is the process when the destination line number and the current line number are the same (here, the destination line number and the current line number are both "10j").

Next 1: Processing when the destination and current line number are different will be explained. In S30, the destination line number (, r20
J ) and the current line number ("10") are determined to be different (the station number b(r
304. r40) J and the number c of the crossing position in the destination direction
(r40J) is the same (S90
). Crossing position numbers CF As shown in Table 2, there are set numbers for the ascending direction indicating the crossing position to the line in the ascending direction, and those for the descending direction indicating the crossing position for the descending direction line.

In S90, the number c (r40J) of the crossing position with respect to the destination line direction and the station number b of the current location
(r30", r40., +), that is, the current distribution is determined that the hanger rail 3 for communicating with the hanger 46 in the destination direction is connected to the device 5] Next, the destination line number (r20J)
It is determined whether or not is larger than the current line number (rlOJ) (S100).

If the destination line number is larger than the current line number (for example, if the destination is "20" and the current line number is "]O"), the hanger 46 is moved to the side where the line number increases (from rl OJ to 2o) is executed (SIIO). On the other hand, if the destination line number is not larger than the current line number (for example, if the destination is "]0" and the current is "20"), move the hanger 46 to the side where the line number decreases (from r20J to [] 0)) is executed (S120).

In S90, if it is determined that the current location number C is not the same as the crossing location number C (for example, the current location is r30),
r40" and the crossing is "60") In other words, if it is determined that the current allocation cannot be directly transferred from the device 5 to the adjacent line 1 (the number C of the crossing position in the direction of the next destination line is “a≧c) bJ, or [a≦
Determine whether the relationship c<bJ exists (S130)
. (The cross-over position distribution is the case where the device 5 is connected to the destination processing station PS, and the current location distribution is the case where the device 5 is located between the device 5 and the current location.)

If rYESJ is determined in step 5130, then it is determined whether the destination station number a is greater than the station number of the current location (S] 40). As a result of this determination, it is determined that a>b. [1 hanger 46 is sent to the side where the station number increases (S1
50). On the other hand, if it is determined that a>b is not the case, the hanger 46
Performs processing to send the station number to the side where the station number decreases (
S160). By processing these S] 30 to 5160,
The hanger 46 (the portion at the front crossing position is transferred toward the device 5).

If rNOJ is determined in the judgment of 3130 (in other words, the distribution of the crossing position is that the device 5 is connected to the destination processing station PS, and the distribution of the current location is between the device If it is not located, then it is determined whether the destination station number a and the current location station number are between two crossings (S170). Being between two crossings means a, The distribution of crossing positions is based on the case where the device 5 is present on both the ascending and descending sides of b.

If it is determined in step 5170 that a and b are between the two crossings, then processing is performed to go from the current location to the destination in the shortest distance.In other words, next, the destination station number and The difference between the number of the nearest crossing and the difference between the station number of the current location and the number of the nearest crossing are calculated, and the crossing corresponding to the smaller of the two calculated differences is determined. The process of sending the hanger 46 to the side is executed (S180).

5170, if a and b are not between two crossings, that is, if the crossing is on one side, one table
Next, the process of sending the hanger 46 to this crossing side is executed (
S190-8270). That is, next, it is determined whether the destination station number a and the station number of the current location are the same (S190). If a and b are the same, the hanger 46 is sent to the number C side of the crossing position (
S200).

5190, if a and b are not the same (
Next, it is determined whether the destination station number a is greater than the current location station number (S210). a
>b, it is determined whether there is a transition on the side where the station number increases next (S220). If there is a transition on the side where the station number increases (e), the process of sending the hanger 46 to the side where the station number increases is executed (S230).On the other hand, if there is no transition on the side where the station number increases (the hanger 46 is transferred to the station A process of sending the number to the side whose number is decreasing is executed (S240).

If a>b is not found in step 5210, then it is determined whether there is a transition on the side where the station number decreases (S250). If there is a transition to the side where the station number is decreasing (S260), the hanger 46 is sent to the side where the station number is decreasing (S260).

On the other hand, if there is no crossing to the side where the station number is decreasing, a process is executed to send the hanger 46 to the side where the station number is increasing (S270').

5210-3270, the hanger 46 is sent toward the destination station number in a short distance and without entering a dead end.

The above-mentioned hanger conveyor line 1 (Table 1) The above-described branching processing of the hangers 46 is individually executed by the device 5, and the hangers 46 are conveyed to the destination processing station PS.

In addition, the new distribution to the above-mentioned hanger conveyor line is to machine 5Af and processing station PSAfa-PSA.
When adding fb, the network can be expanded simply by adding a control circuit 7Af having data as shown in FIG.

As explained above, the device 5 determines the destination of each hanger 46 on the hanger conveyor line 1 (by using the line number assigned in ascending order from one end side to the other end side) and one end of the line. Compare the station numbers assigned in ascending order from the end side to the other end side corresponding to the processing stations PS, the crossing numbers, and the destination lines and station numbers assigned to each hanger 46. As a result, for each hanger distribution, the device 5 uses the line number, the ascending and descending direction of the line number, the crossing number, the number of the processing station to be directly branched and conveyed, and the ascending and descending direction of the processing station number. By simply storing the information in advance, the predetermined hangers 46 can be transported to destinations predetermined for each hanger 46. Therefore, the device only needs to individually memorize predetermined numbers for each hanger. In other words, when expanding the hanger conveyor line 1 or adding or deleting a predetermined number of hangers from the processing station to the device 5, the data stored only in the device is stored for the expanded or changed number of hangers. All you have to do is change this:
This has the extremely excellent effect of reducing the number of man-hours and time required to expand or change the hanger conveyor line.

Note that the present invention is not limited to the above-mentioned embodiments, and various embodiments can be implemented without changing the gist of the present invention. For example, it may be used in a networked conveyance line that combines a conveyor and a turntable.Also, a command device may be connected to each control circuit, and an identification number-destination number target table may be written from each station. Good.Furthermore, the identification number-destination number target table may be stored in the memory in the command device 8 and the destination side may be executed by communicating with the control circuit 7. [Effects of the Invention] Network-like conveyance line of the present invention The control device determines the branching of the transport body by the branching means, and is configured based on identification symbols provided for each branching means (2 and each transport line), and also based on branching data set for each branching means. This is done by

With this, it is possible to change only the branching data set for the branching means that has been added or changed from the addition or change 1 of the conveyance line or branching means.

Therefore, an excellent effect is achieved in that the number of man-hours and time required for adding or changing the network-like conveyance line can be reduced.
