By the way, the applicant of the present invention is
The sliver splicing robot (sliver piece robot) that moves on the can containing the sliver S and connects the sliver S as appropriate, and the ceiling conveyor that carries in and out the empty can and the actual can, and the operation status of the pneumatic spinning machine 1 In line with this, we have developed a system that controls these and automatically replaces the can that supplies the sliver S to the spinning unit 2. With this can exchange system, smooth sliver (can) supply is realized and labor saving is achieved.

In this system, however, it is necessary to stop spinning when the sliver splicing robot is performing sliver splicing, and to immediately start knotting by the yarn splicing cart to restart spinning when the sliver splicing is completed. Conventionally, there has not been a spinning device configured to smoothly perform the spinning.

Therefore, in view of the above circumstances, the present invention was devised to provide a spinning device capable of splicing yarns appropriately corresponding to can replacement.

[0007]

SUMMARY OF THE INVENTION The present invention relates to a spinning apparatus in which spinning of a spinning unit is stopped by a sliver splicing robot to perform sliver splicing, and when the sliver splicing robot finishes sliver splicing, the yarn splicing is performed on the spinning unit. A spinning start lamp is provided to notify the bogie to the yarn splicing request.

[0008]

With the above construction, the yarn splicing cart detects the spinning start lamp and splices the spinning unit after the sliver splicing is completed to start spinning.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the figure, the same components as those in the related art are designated by the same reference numerals.

First, referring to FIGS. 3 and 4, a can exchange system in the pneumatic spinning machine 1 to which the present invention is applied will be described. In this system, the cans K for storing the sliver S are arranged in three rows on the back side of the pneumatic spinning machine 1. Of these, two rows, for example, the first and second rows, are the cans K being fed by the sliver. _The spare cans K ₁ and K ₂ in the remaining row (third row) are used as spare cans K _3, and the cans K ₁ and K ₂ being supplied correspond to each spinning unit 2 in a staggered arrangement. An empty can station 21 for carrying out empty cans and an actual can station 22 for carrying in actual cans are provided at both ends of the can row, and these stations 21, 22 and the actual can supply place (drawing machine) 23 are provided.
A ceiling transport vehicle 25 is configured to travel along a track 24 that connects to and. This ceiling transport vehicle 25 is driven by a command from a can transport control device (not shown) to carry the actual can from the actual can supply location 23 to the actual can station 22 and to supply the empty can from the empty can station 21 to the actual can. It is carried out to the place 23. There is a conveyor (not shown) at the bottom of the can row, and by driving the conveyor from the actual can station 22 toward the empty can station 21, loading and unloading can be carried out row by row. Further, a sliver splicing robot 27 is provided on the back side of the pneumatic spinning machine 1 so as to be able to move along the spinning unit 2, and is self-propelled to the spinning unit 2 which requires a can exchange according to an instruction from a control panel (not shown). It is designed to perform sliver piecing.

With this configuration, as shown in FIGS. 5 and 7, when the spinning unit 2 to be replaced and the can K (row) are determined by the instruction of the operator, and it is confirmed that a new can is installed, Sliver splicing robot 2
The operation by 7 is started. This operator's instruction is only for the first replacement, after that the control board that counts the sliver constant length by the spinning time sends a signal to the spinning unit 2 (machine main body), and the spinning unit 2 displays the piecing request with a lamp. Notify the sliver connecting robot 27. In parallel with this, the control panel commands the sliver joint robot 27 to run and resets the sliver constant length. Since the consumption of the sliver S of each spinning unit 2 proceeds substantially in the same manner, the individually displayed piecing lamps are omitted, and the spinning units 2 to be replaced can be sequentially replaced from the row end side. May be performed.

When the sliver splicing robot 27 arrives at the spinning unit 2, the sliver splicing robot 27 stops the spinning and then performs the sliver splicing. For example, as shown in FIG. 4, the sliver S ₂ of the second row of cans K ₂ being fed is cut, and the end of the sliver S ₃ of the third row of cans K ₃ is fed to the sliver on the spinning unit 2 side. Connect to end S ₀ . When the sliver splicing is completed, the yarn splicing carriage 9 is notified of the knotting request, and the yarn splicing carriage 9 is moved to the origin position or the next spinning unit 2. The control panel notifies the can transfer control device that the sliver splicing robot 27 can be carried out when the robot 27 reaches the origin position, and after carrying out the empty can (the can with the minimal sliver) by the ceiling transfer vehicle 25,
A new real can is loaded into the unloading position or an appropriate position with a half pitch offset.

The features of the spinning device of the present invention relate to the operations of the sliver splicing robot 27, the spinning unit 2 and the yarn splicing carriage 9 described above. Figure 1
An embodiment of the spinning device will be described below.

In this spinning device, a switch pushing rod 31 provided in the sliver splicing robot 27, a micro switch 32 and a spinning start lamp 33 provided in the spinning unit 2, and a yarn at a position opposed to the spinning start lamp 33. A lamp detection sensor 34 provided on the joint vehicle 9 is provided. The micro switch 32 is provided on the back side of the upper part of the spinning unit 2, and includes a spinning stop switch 35 that stops spinning when turned on and a lighting switch 36 that lights the spinning start lamp 33 in parallel at one location. The switch push rod 31 is attached to both switches 3
5 and 36 are operated at the same time. The spinning start lamp 33 is attached to a wall portion facing the internal space of the spinning unit, and is formed so as to light up when the lighting switch 36 changes from ON to OFF. When the lamp detection sensor 34 detects that the spinning start lamp 33 is turned on, the lamp detection sensor 34 unconditionally stops the traveling of the yarn splicing cart 9 and executes the yarn splicing.

Next, the operation of the above embodiment will be described (see FIG. 2).

When the sliver joining robot 27 receives the piecing command (sliver constant length signal), it moves from the origin position to the spinning unit 2 (ST 1). When it reaches the predetermined position of the spinning unit 2, the switch pushing rod 31 is advanced and the micro switch 32 is operated.
When the spinning stop switch 35 is turned on (ST2), the draft device 6 of the spinning unit 2 is stopped and the yarn Y is cut. At this time, the black button 14 is projected and the red flag 15
The solenoid 17 is turned off and the red flag 15 pops out, which indicates that the sliver is being connected. That is, since the red flag 15 is protruding, the yarn splicing cart 9 passes through the spinning unit 2. In addition, even if the operator accidentally pushes in the red flag 15,
Since the solenoid 17 is off, only the black button 14 is not projected (see FIG. 9C). Moreover, since the electromagnetic clutch of the black button 14 is also in the OFF state, the operator or the like does not spin the sliver. Therefore, the sliver is not moved unnecessarily during the sliver joining operation.

When the sliver joint is executed (ST 3) and the sliver end of the new can and the sliver end of the spinning unit are connected (ST 4), the switch pushing rod 31 is retracted and the micro switch 32 is turned off. (ST 5).
That is, the lighting switch 36 changes from ON to OFF, and the spinning start lamp 33 is turned on. Lamp detection sensor 34
As a result, the yarn splicing carriage 9 that senses this stops at the position of the spinning unit 2 and knotting is executed. At this time, when the spinning stop switch 35 is turned off, the solenoid 17 of the red flag 15 is turned on. If thread splicing is successful, the black button 14 is pressed and the electromagnetic clutch of the draft device 6 is pressed, as in the case of a normal slab break. Becomes "ON" and spinning is restarted. If the spinning fails, the red flag 15 remains protruding (pushed in once and then projected), and the operator is called.

Then, the sliver splicing robot 27 moves away from the spinning unit 2 to the spinning unit 2 or the origin position where the next piecing is required (ST 6),
One cycle of the can replacement operation is completed (start of can loading / unloading).

In this way, the sliver joint robot 27
After stopping the spinning of the spinning unit 2 by operating the micro switch 32 and then performing the sliver splicing, when the sliver splicing is finished, the spinning start lamp 33 is turned on to notify the yarn splicing cart 9 of the yarn splicing request. Therefore, the can replacement and the yarn splicing are smoothly and quickly performed, and there is no fear of malfunction by the yarn splicing carriage 9 or the operator during the sliver splicing. That is, a piecing well adapted to the can change system is achieved.

As a mechanism for notifying the yarn splicing carriage 9 of the knotting prohibition and the knotting request, for example, a full lamp (not shown) provided in each spinning unit 2 is used.
It is also conceivable to do this by blinking the pulse. However, in this mechanism, the knotting prohibition and the knotting request must be discriminated by the duty ratio of the pulse, and it is difficult to detect while the yarn splicing carriage 9 is running, so there is a risk of misjudgment. Further, it is necessary to add a complicated control mechanism for causing such pulse blinking. Then, the yarn splicing cart 9 pushes the red flag 15 once when the end of the can replacement is sensed, and the yarn splicing is performed when it returns again, so that it takes a long time before the spinning is restarted. According to the present invention, it is possible to prevent such problems from occurring.

The present invention can be applied to a semi-automatic can changing system as shown in FIG. 6 in addition to the fully automatic can changing system shown in FIGS. In this semi-automatic exchange system, the operator monitors the consumption state of the sliver, commands the exchange (remaining) can position and the new (spare) can position, and the sliver joining robot 2
7 is operated. Sliver splicing robot 2
The display lamp 7 lights up the operator by moving the display lamp during the movement or the sliver joint operation. The other operations of the sliver splicing robot 27 and the operations of the spinning unit 2 and the ceiling transfer vehicle 25 are the same as those in FIG.

[0022]

In summary, according to the present invention, the yarn splicing is reliably and quickly performed after the can is exchanged, and the yarn splicing well adapted to the can exchange system is achieved, which is an excellent effect.
