    Description
    BACKGROUND OF THE INVENTION The present invention relates to a combing machine formed by a line of a plurality of combing machines, each comprising a device for connecting plies.
    When a tablecloth fastening device is driven in one of a plurality of aligned combers, a lock is activated in the tablecloth fastening devices of other combers. Japanese pending patent publication No. 5-140,824 describes an apparatus in which a control device for each combing machine is connected to a central control unit. When the tablecloth fastening device is driven in one of the combing machines, the central control unit simultaneously locks the control devices of the other combing machines. Japanese pending patent publication No. 58-41,918 describes, as a hardware-configured lock above, a lock for a spinning loom equipped with a simultaneous can change mechanism. This structure allows the target comber to be activated only when one of the adjacent combers is in a waiting position. This prevents the simultaneous activation of adjacent combers.
    The technique of publication of pending Japanese patent n ° 58-41 918 can be applied to the locking intended for attaching operations of combing machines. For example, when one of three or more combing machines performs a reattachment operation in order to change the tablecloths, the tablecloths fixing devices of the other combers must be deactivated. This requires that a home operation signal line be continuously connected to all other combers. Thus, a signal line must come from each of the aligned combers. In this case, the signal lines that connect combers located close to each other may be short. However, the signal lines which connect combing machines located far from each other are long. Thus, the connection is complicated. SUMMARY OF THE INVENTION An object of the present invention is to provide a combing device which performs locking with a simple connection during random attachment operations.
    In order to solve the above problem, a first aspect of the present invention provides a combing device formed by a line of a plurality of combing machines, each comprising a device for attaching plies. The combing device includes a first relay provided in each combing machine. Each of the first relays includes a normally closed contact B which opens when the corresponding combing machine performs an attachment operation. The combing device also includes a second relay provided in each combing machine. Each of the second relays includes a normally open contact A which opens when another combing machine carries out an attachment operation. The combing apparatus further includes a controller provided in each comber. The controller is connected to the normally open contact A of the second relay. Each comber includes a first line into which the normally closed contact B of the first relay is inserted, a second line, a third line, and a fourth line which serves as a common line. The first line of each of the combers, the second line of each of the combers, the third line of each of the combers, and the fourth line of each of the combers are connected in series. One end of the first lines is connected to one end of the second lines in one of the combers which is at a terminal end of the combers. Another end of the first lines is connected to one end of the third lines in one of the combers which is at another terminal end of the combers. A power supply is connected to the third line and to the fourth line. A coil of the second relay of each of the combers is connected in parallel between the second line and the fourth line. The controller detects a reconnection operation performed in another combing machine from a state of the normally open contact A of the second relay.
    Other aspects and advantages of the present invention will become apparent from the following description, taken in conjunction with the accompanying drawings, which illustrate by way of example the principles of the invention.
    Brief Description of the Drawings The invention, with the objects and advantages thereof, can be better understood with reference to the following description of the currently preferred embodiments, with the accompanying drawings, in which:
    Fig. 1 is a diagram illustrating a combing apparatus according to an embodiment of the present invention;
    Fig. 2 is a sequence diagram which illustrates the combing apparatus; and
    Fig. 3 is a diagram which illustrates the connection between combing machines for comparison.
    Detailed description of the preferred embodiments [0008] A combing apparatus according to an embodiment of the present invention will now be described with reference to the drawings.
    As illustrated in FIG. 1, several combing machines 20, 21,22, ..., 23 are aligned in order to form a combing apparatus 1. The combing machines 20, 21,22, ..., 23 each comprise a device for attaching plies 10.
    Each of the combers 20, 21, 22, ..., 23 includes a plurality of combing heads. A web is unwound from a web winding body to a combing tool. The tablecloth is combed by the combing tool. The tablecloths fastening device 10 removes the pieces of tablecloths which have been cut. Each combing head includes suction nozzles. Each suction nozzle is connected to a suction pipe 11 by a threaded pipe. The suction pipe 11 of each of the combers 20, 21, 22, ..., 23 is connected to a single collective duct 12. Each suction pipe 11 comprises a closing mechanism 13. The collective duct 12 is in communication with a fan 15, which can be driven by a drive motor 14, and a drum separator 16, which serves as a fiber separator. The combers 20,21,22, ..., 23 include control devices 30, 31,32 and 33, respectively. The control devices 30, 31, 32 and 33 automatically change the sheet winding bodies.
    The pieces of tablecloths are collected from each of the combing machines 20, 21, 22, ..., 23. In order to change the sheet winding bodies, the pieces of tablecloths are cut from the tablecloth and are sucked into the suction nozzles. The pieces of tablecloths then reach the drum separator 16 via the collective duct 12. The tablecloth winding body is changed when the majority of the tablecloth has been unwound from the tablecloth winding body. The tablecloth is cut at a particular section. The pieces of tablecloths cut from the tablecloth are removed. Then a new web winding body is used. A ply from the new ply winding body is also cut at a particular section. The start of the new unrolled tablecloth is joined to the end of the previously unrolled tablecloth.
    Each combing head comprises a sensor S1. When the web is fully unwound from the web winding body in one of the combing heads, the sensor S1 transmits a start signal to one of the corresponding control devices 30, 31, 32 and 33. Thus, when 'An attachment operation is triggered by one of the combers, the control devices 30, 31, 32, and 33 of the other combers are locked at the same time. Thus, while a tablecloth winding body is changed in one of the combers, the tablecloth winding bodies cannot be changed in the other combing machines. The control devices of the other combing machines are locked because the suction pressure must be maintained at a certain level in order to remove a piece of tablecloth through the reattachment operation. Thus, the controllers of the other combers are locked in order to prevent any situation in which the suction pressure decreases and the piece of tablecloth remains without being sucked.
    As illustrated in FIG. 2, each of the combers 20, 21, 22, ..., 23 comprises a controller 40, a relay card 41, and a power supply of controller 42. The controller 40 comprises a microcomputer provided with a CPU as a component main. The controller power supply 42 is, for example, a 24 V power supply.
    Each relay card 41 includes a first relay CR1 and a second relay CR2. The first CR1 relay comprises a normally closed contact B 50 (closing contact) and a coil 51. In the first CR1 relay, when the corresponding combing machine performs a reconnection operation, the coil 51 is energized in order to open the normally closed contact B 50. The second relay CR2 comprises a normally open contact A 60 (circuit establishment contact) and a coil 61. In the second relay CR2, when another combing machine performs a reconnection operation, the coil 61 is de-energized and the normally open contact A 60 is open. The controller 40 triggers the first relay CR1 to indicate that the corresponding combing machine is performing an attachment operation.
    Each relay card 41 includes a DC / DC power supply circuit 43. The DC / DC power supply circuit 43 is connected to the controller power supply 42. The DC / DC power supply circuit 43 is supplied with an energy which comes from the power supply of controller 42 in order to generate a predetermined voltage, for example, of 12 V. In each of the combers 20, 21, 22, ..., 23, the coil 51 of the first relay CR1 is connected to the controller 40. In each combing machine 20, 21, 22, ..., 23, the normally open contact A 60 in the second relay CR2 is connected to the controller 40.
    In each combing machine 20, 21, 22, ..., 23, the relay card 41 includes a first line L1, a second line L2, a third line L3, and a fourth line L4 which serves as a common line . The normally closed contact B 50 in the first relay CR1 is inserted in the first line L1. The first lines L1, the second lines L2, the third lines L3, and the fourth lines L4 of the combing machines 20, 21, 22, ..., 23 are connected in series by electric wires situated between the combing machines 70 which serve as wires electric to four souls.
    The comber 23 is at one end of the aligned combers, and the comber 20 is at the other end. In the combing machine 23, a return loop wire W1 connects one end of the first lines connected in series L1 and one end of the second lines connected in series L2. In the combing machine 20, a return loop wire W2 connects the other end of the first lines connected in series L1 and one end of the third lines connected in series L3. Thus, the line L1 continuously connects the normally closed contact B 50 in the first relay CR1 of the combing machines, and the line L1 is sent back to the level of the combing machines 20 and 23 at the terminal ends in order to continuously connect the lines L2 and the lines L3 .
    The power supplies of controllers 42 are connected to the third lines connected in series L3 and to the fourth lines connected in series L4 via the DC / DC power supply circuits 43. Each of the combers 20, 21, 22, ..., 23 includes the DC / DC power supply circuit 43 which serves as a sequential power supply circuit. Each DC / DC power supply circuit 43 is connected to the third lines connected in series L3 and to the fourth lines connected in series L4.
    The coils 61 of the second CR2 relays in the combers 20, 21, 22, ..., 23 are connected in parallel between the second lines connected in series L2 and the fourth lines connected in series L4. Thus, the coils 61 of the second relays CR2, which indicate that the corresponding combers carry out attachment operations, are connected between the second line L2 and the fourth line L4. The controller 40 monitors the state of the normally open contact A 60 in the second relay CR2. The controller 40 detects the attachment operations of the other combing machines from the state of the normally open contact A 60 in the second relay CR2.
    The first line L1, the second line L2, and the third line L3 serve as lines for connection operation signals, and the fourth line L4 serves as a common line (ground line). A common control power supply line L10 connected to the normally open contact A 60 of each of the combers 20, 21, 22, ..., 23 is isolated from the third line L3 and from the fourth line L4, which are connected to the DC / DC power supply circuit 43. In other words, the common control power supply line L10, which serves as a common power supply line for combing machines, is not connected to the fourth line L4, which serves as a common locking power supply line. Thus, the common control power supply line L10 and the fourth line L4 are independent of each other. This limits the situations in which the control devices are affected by the noise that results from the arrangement of the electrical wires.
    The operation will now be described. When none of the combing machines performs a reconnection operation, the normally closed contact B 50 located in the first relay CR1 is closed in each combing machine. Thus, in each combing machine, the coil 61 of the second relay CR2 is excited, and the normally open contact A 60 located in the second relay CR2 is also closed. The controller 40 detects that a reconnection operation is not carried out from the state described above of the normally open contact A 60 in the second relay CR2.
    When one of the combing machines performs an attachment operation, the corresponding controller 40 excites the coil 51 of the first relay CR1 in order to open the normally closed contact B 50 located in the first relay CR1. This de-energizes the coil 61 of the second CR2 relays in the other combing machines in order to open the normally open contacts A 60 in the second CR2 relays in the other combing machines which do not carry out re-attachment operations. Thus, in the other combing machines which do not carry out attachment operations, the controllers 40 recognize that the normally open contacts A 60 located in the corresponding second relays CR2 are open. Thus, combing machines other than the one that performs a fastening operation are locked and cannot perform any fastening operations.
    Thus, a controller 40 triggers a reconnection operation from a state in which the normally open contact A 60 located in the second corresponding relay CR2 is closed by exciting the coil 51 of the first corresponding relays CR1. In this case, the coils 61 of the second relays CR2 located in the other combers are de-energized. This puts the other combing machines in a standby state in which the other combing machines are locked even at a time of rehitching operation. When a combing machine performs an attachment operation, the controller 40 de-energizes the coil 51 of the first corresponding relay CR1. Thus, the other combing machines which do not carry out reconnection operations excite the coils 61 of the corresponding second relays CR2. This cancels the locking of the other combers.
    Thus, in the present embodiment, the combing machines must be connected only by four lines, namely the previous section of the connection operation signal line (L1), the last section of the signal lines. connecting operations (L2, L3), and the common line (L4). This performs interlocking with a simple connection during random reconnection operations.
    In addition, the adjacent combers must be connected by a single type of electric wire 70 located between the combers, which serves as an electric wire for four souls. This simplifies the connection configuration of adjacent combers. Thus, the combers must be connected only by the electric wire located between the combers 70, which serves as an electric wire for four cores in addition to the loop wires W1 and W2 of the relay cards at the level of the combers located at the two ends of the aligned combers. . Thus, the signal wires which connect the combers are not long, and the connection is not complicated.
    The operation will now be described in detail.
    When the bobbin change operation lock of patent 2 is applied to a combing attachment operation lock, the attachment lines signal lines of the other combers must all be connected continuously. For example, as illustrated in FIG. 3, in a connection operation interlock wiring configuration for five combers, a comber 200 and a comber 201 must be connected by electrical wires located between the combers L101 and L105. The comb 200 and a comb 202 should be connected by electric wires located between the combers L102 and L106. The comb 200 and a comb 203 must be connected by electric wires located between the combers L103 and L107. The comb 200 and a comb 204 must be connected by electric wires located between the combers L104 and L108.
    The electrical wires located between the combing machines L101, L102, L103, L104, L105, L106, L107 and L108 each include two wires. The number of threads between the combers is sixteen. In the comparative example of fig. 3, the number of terminals and the number of wires between the combers are increased. In addition, although the combers located close to each other are connected by a short wire, the combers located far from each other must be connected by a long wire. Thus, several types of electric wires having different lengths must be prepared according to the distance between the combing machines. Relay input / output signals must be prepared according to the number of combers. This creates a complicated connection. In addition, since electric wires are used as signal lines, a common long signal line can cause the signal level of the signal line to vary, due to the arrangement of the powerful electric wires within the wires. weak electric. Induction noise can affect combing machines.
    In this embodiment, even if the number of combers increases, the electric wire located between the combers 70 configured by four-core electric son is used to connect the combers. This performs interlocking with a simple connection during random reconnection operations. In addition, combers cannot be affected by noise.
    The above embodiment has the advantages described below.
    (1) The electric wire which connects the combers is of a unique type, namely the electric wire located between the combers 70, which serves as an electric wire for four cores. Thus, locking is carried out with a simple connection during the random connection operations.
    (2) Each combing machine includes the DC / DC power supply circuit 43, which serves as a sequential power supply circuit. Each DC / DC power supply circuit 43 is connected to the third lines connected in series L3 and to the fourth lines connected in series L4. Thus, even when the power supply to one of the combers stops, the continuous connection of the DC / DC power supply lines (lines L3, L4) mounted in the combers allows the DC / DC power supply circuits 43 of the other combers operate as an emergency power supply. This maintains the electrical supplies of the coils 61 of the second CR2 relays. Thus, the relay contacts are not inadvertently interrupted when the power supplies stop. Thus, in the prior art, when the power supply stops in an adjacent combing machine, a lock can be applied by erroneous detections caused when a relay is interrupted. In this embodiment, energy is supplied from the power supplies of other combers. This restricts the wrong lock.
    (3) The common control power supply line L10 is isolated from the third line L3 and the fourth line L4, which are connected to the DC / DC power supply circuit 43. Thus, the common line d control power supply L10 is isolated from the common line (fourth line L4) of the relay card 41 at the DC / DC power supply circuit 43. This reduces the influence of noise on the combing machines.
    It should be apparent to those skilled in the art that the present invention can be incorporated into many other specific forms without departing from the spirit or the scope of the invention. More particularly, it should be understood that the present invention can be incorporated in the following forms.
    In the controller 40, a predetermined order of priority for triggering the reconnection operation from the moment when the normally open contact A 60 located in the second relay CR2 opens can be defined for each combing machine. Thus, the triggering time of the attachment process for each comber can be delayed according to the priority order of the comber.
    More specifically, a timer function is provided for the CPU of each comber in order to delay the operation of each comber in order of priority when several combers are locked at the same time. Some combers can be activated three seconds later, and another combers can be activated five seconds later. In detail, a program is executed in order to perform a lock delay operation. Thus, when two or more combing machines go at the same time to a linking operation state, the controller of each combing machine can define the delay time of the triggering of the linking operation operation after the coil 61 of the second relay CR2 has been excited then de-energized (from ON to OFF). Thus, the order of priority is defined in order to guarantee locking.
    Alternatively, the combing machines can be connected by a communication line in order to adjust the moment of triggering of a fastening process. More specifically, the locking delay operation can be controlled by serial communication or a LAN connection. When communication or a LAN connection is possible between combing machines, information is exchanged before a linking operation in order to determine the order of priority of the connection operation for each combing machine.
    Consequently, the present examples and embodiments should be considered as illustrative and not restrictive, and the invention should not be limited to the details indicated here, but may be modified within the scope and the scope of the invention. equivalence of the appended claims.
