Reference numeral 50 denotes a conveyance order determining device built in the central control device CCB, which receives a conveyance request signal from the spinning control device SCB and a constant setting device 51 for setting the allowable waiting time limit for each fine spinning machine in the constant register 56. a controller 52 that receives a setting signal of
The controller 52 is motivated by periodic signals from the timer 53 to set a constant register 56, a wait limit remaining time register 57, a machine number and status flag register 58, a minimum wait limit remaining time register 59, and a decision machine register 60. Numerical values in the register group are set, moved, added, compared, etc., and furthermore, based on the determined machine number register 60, a conveyance order determining signal is inputted to the spinning machine racking SCB from lines 601 to 630 via an interface 61.

PTM is a sequence programmer built into the central control unit CCB, and has output switches P1 to P26 for operation,
It has input switches 81 to S2 for self-stepping, and a time chart of these is shown in FIG.

Further, FIG. 9 shows a wiring diagram of the spinning control device SCB, and FIG. 11 shows a wiring diagram of the finishing control device WCB.

Next, the operation of the apparatus of the present invention is described. For example, when the doffing operation of the spinning machine SP1 is completed, the full box F containing the pipe yarn wound by the spinning machine SP1 is transferred to a winding machine that rewinds the pipe yarn. The case of transferring to the finishing conveyor table SC1 corresponding to W1 will be explained.

Note that the finishing conveyor table SC1 is set in advance by the pinboard matrix MTR shown in FIG.

(1) In Figure 7, prior to system operation,
The machine numbers of the spinning machines SP1 to SP3o and the spinning machines SP1 to S are input by the input digital switch of the constant setting device 51.
The allowable waiting time limit corresponding to one docking (one production cycle) of P3o is set, for example, in minutes, and input using a push button switch.

In response to this push button signal, the controller 52 registers the allowable waiting limit time signal indicated by the digital switch in the register for the spinning machine in the constant register 56.

Note that each time the production type is changed, the production speed is changed, etc., the constant register is set by the constant setting device 51. 56 constant tables can be updated.

At the start of the transfer cycle, the sequence programmer RTM is in step 1 in FIG. 8, and the output switch P
3. Assume that P7 is on, power is applied between the end line 31a and the home base stop line 30 in FIG. 2, and the transport vehicle T is stopped at the home base HB.

(2) After the conveyance cycle starts and the doffing operation of the spinning frame SP1 ends, the tube yarn is transferred from both sides of the spinning frame SP1 to the spinning frame SP1.
The call signal is sent to the two empty boxes on the relay trolley D1 located at the end, and is issued when the boxes are full.
By pressing the pushbutton PB1 on line 201 in the figure and turning on the switch LS on line 202 when automatic is set, turn on the key relay R4k on line 202 in Figure 9, and its contact R
4K turns on relay R4-1 of line 205, and inputs a transport request signal generated by turning on contact R4-1 of line 500 in FIG. 7 to interface 54 of transport order determining device 50 through line 501.

(3) On the other hand, based on the signal from the timer 53, the controller 52 scans the interface 54 every minute to check for a transport request signal, and if the above input is received, the controller 52 sends the signal for SP1 in the machine number and status flag register 58. Set the transport request acceptance flag in the register, and set the SP of the constant register 56 and the SP of the waiting limit remaining time register 57 for the allowable waiting limit time.
Move to 1 register.

Note that when there are no spinning machines SP1 to SP3o requesting transport, this is indicated by the transport request general flag in the machine number and status flag register 58, and when the transport request input table has already accepted the transport request, This is checked using the request acceptance flag, and the relevant machine register 1 of the waiting limit remaining time register 57 is checked.
decrease.

As a result, among the wait limit remaining time registers 57, the register for which the transport request has already been accepted indicates how many minutes the relevant stand can wait for transport.

At the start of the transport cycle, the sequence programmer PTM is in step 1, and as shown in FIG. 8, the output switch P26 is turned on and outputs a transport order request determination signal to the line 134.

Upon receiving this signal, the controller 52 first refers to the transportation request acceptance general flag, and if it has not received any transportation requests, it waits, and if it has received any transportation requests, it registers in the waiting limit remaining time register 57 whether the transportation request has been accepted or not. The machine number corresponding to the register showing the minimum value among the registers is extracted from the machine number and status flag register 58.

Specifically, an arbitrary sufficiently large value is entered in the minimum waiting limit remaining time register 59, and the waiting limit remaining time register 57 is
and the machine number and status flag register 58 are checked one by one, and when the value of the transport request accepted register in the waiting limit remaining time register 57 is smaller than the minimum waiting limit remaining time register 59, that machine number and The waiting limit remaining time is determined by the machine number register 60 and the minimum waiting limit remaining time register 5.
9 and repeating this over all registers, the machine number with the minimum waiting limit remaining time is extracted into the determined machine number register 60.

When the ranking determination request signal is received, the controller 5
2 is an input line 6 which inputs the machine number extraction signal to the spinning control device SCB through an interface 61 as a ranking determination signal.
To any one of 01-630, spinning machine SP1-S
Specify one of P3o.

In this case, only the contact R4-1 of the line 500 is on, so the machine number of the spinning machine SP1 and its waiting limit remaining time are transferred to the minimum waiting limit remaining time register 59 and the determined machine number register 60. , therefore, the spinning machine SP1 is specified through line 601.
