DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal crimping system, and more particularly, to a crimping device main body, a wire feeding device for feeding an electric wire to the crimping device main body, and a wire conveyed by the crimping device main body. The present invention relates to a terminal crimping system including a conveyor.

[0002]

2. Description of the Related Art Conventionally, as a crimping mechanism, a crimping device main body has a column member which is vertically erected, a guide member disposed above the column member, and a lower portion of the column member. And a base. And, at the lower end of the guide member,
The pressing member protrudes and is attached, and the guide member and the pressing member move up and down by the power mechanism. That is, when the pressing member moves downward, the crimp terminal is crushed between the distal end of the pressing member and the concave anvil formed on the base.

Further, the terminal crimping device is provided with a terminal feed mechanism mechanically linked to the operation of the pressing member, and the crimping terminal is crushed and the pressing member is displaced from the bottom dead center side to the top dead center side. Each time, a new crimp terminal is sequentially fed into the base anvil. Then, the crimp terminal sent to the anvil is crushed by the pressing member after the electric wire is inserted.

By the way, when the electric wire is fed into the crimp terminal or the electric wire is discharged after the crushing operation, the operation takes a long time, and the productivity is low. It is also difficult to incorporate them into a part of a factory line. Therefore, when the crimp terminal is crushed, the tip of the wire is automatically sent to the crimp terminal, and after the crimp terminal is crushed, the wire to which the crimp terminal is crimped can be automatically moved to a predetermined position. 2. Description of the Related Art A terminal crimping apparatus including a mechanism and a cutting mechanism that automatically cuts an electric wire and removes a covering material at an end of the electric wire is known. According to this, first, the covering material on the distal end side of the electric wire is removed, and the distal end of the electric wire is inserted into the crimp terminal mounted on the anvil of the base. Then, the crimp terminal is crushed by the operation of the power mechanism. After that, the wire with the crimped terminal crimped is sent by a predetermined length by the wire feed mechanism,
It is cut by the cutting mechanism. As described above, every time the crushing operation is performed, the moving operation and the cutting operation of the crushed electric wire are performed, and subsequently, the covering material removing operation of the newly fed electric wire and the feeding operation to the crimp terminal are sequentially performed. The length of the electric wire to be processed can be set to an arbitrary length by a length setting means provided in the operation unit.

Further, the electric wire supplied to the electric wire feeding mechanism of the crimping device main body is fed by an electric wire feeding device provided separately from the crimping device main body. The wire feeding device is a so-called pre-feeder, which feeds a wire in a winding state to the crimping device main body at a predetermined speed, and can supply the wire without applying a load to the wire feeding mechanism. Specifically, the electric wire feeding device includes a feeding mechanism for feeding an electric wire by an operation of the electric motor, and adjusting means for adjusting the feeding speed of the electric wire, that is, the rotation speed of the electric motor to a predetermined speed. The feeding mechanism is controlled independently of the crimping device main body, and always feeds out the wire at a predetermined speed regardless of the operation state of the crimping device main body. That is, in the crimping device main body, when the wire feeding mechanism is not operating, for example, during the operation of the crimping mechanism, the wire fed out by the feeding mechanism is not used and thus becomes excessive. When the wire is fed by a predetermined length by the wire feeding mechanism of the crimping device main body, the surplus wire is used. Further, the adjusting means continuously performs the crimping operation of the crimp terminal so that the length of the surplus electric wire fed out by the feeding mechanism matches the length of the electric wire sent by the wire feeding mechanism of the crimping device main body. When the operation is performed, the feeding speed is adjusted so that the fed wire does not become excessive or conversely, the fed wire runs out. Is adjusted to

[0006] Some crimping apparatus bodies have a discharge mechanism. The discharging mechanism is for discharging the processed electric wire, that is, the electric wire to which the crimp terminal is crimped, to a predetermined position, for example, by holding the tip of the electric wire and moving it to a predetermined position. By the way, the length of the electric wire to be processed varies, and when it is long, it may exceed 1 m. And such a long electric wire cannot be accommodated on the crimping device main body, and even if it can be accommodated, in order to eject these electric wires, the movable mechanism provided in the ejection mechanism is required. The moving amount of the part becomes extremely large, and the discharging mechanism becomes large.

Therefore, recently, a belt conveyor having a required length is provided on the discharge side of the crimping device main body independently of the crimping device main body. This belt conveyor (hereinafter, simply referred to as “conveyor”) includes an electric wire housing formed on a side of the belt in parallel with the conveying direction. Therefore, in a state where the front end of the processed electric wire is placed on the belt of the conveyor and the rear end of the electric wire is held by the holding portion of the discharging mechanism, the holding portion of the discharging mechanism is moved to the wire housing portion side of the conveyor. Thereby, the electric wire is guided to the electric wire housing portion side while being conveyed in a straight state by the conveyor. Then, when the holding portion of the discharge mechanism moves to the vicinity of the wire housing, the rear end of the wire is released, so that the wire is housed in a predetermined position of the wire housing in a linear state.

If the conveyor speed is lower than the optimum speed corresponding to the discharge speed, the moving speed on the rear end side of the electric wire is faster than the moving speed on the front end side of the electric wire. As a result, the wire is bent, and the wire is housed in the wire housing portion in a bent state. Conversely, if the conveyor speed is higher than the optimum speed, the wires will not bend, but the conveyor speed is higher than necessary, and energy such as electric motor power is wasted. Would. Therefore, there is known a conveyor provided with a speed adjusting means so that the conveyor speed can be adjusted to an optimum speed corresponding to the discharge speed.

[0009]

However, in the case where the wire feeding device is provided for feeding the electric wire to the crimping device main body, the wire feeding speed becomes a speed corresponding to the processing capacity of the crimping device main body. As described above, it was necessary to adjust the position using an adjustment knob or the like. In other words, it must be adjusted every time the length of the wire processed by the crimping device body is changed, and in the adjustment, firstly, appropriately adjust based on the experience of the worker, and then, Fine adjustment has to be performed while checking the operation state of the crimping device main body and the wire feeding device state, so that much time has been required for the adjustment work.

[0010] Further, even in the case where a conveyor is arranged on the discharge side of the crimping device main body, the conveyor speed must be adjusted to an optimum speed in accordance with the discharge speed of the electric wires, and the adjustment work is troublesome. Met.

Accordingly, an object of the present invention is to provide a terminal crimping system capable of automatically adjusting a feeding speed of a wire feeding device or a conveying speed of a conveyor, thereby eliminating an operator's adjustment work. Things.

[0012]

According to a first aspect of the present invention, there is provided a terminal crimping system including a crimping device main body and an electric wire feeding device. The crimping device main body sets a crimping mechanism for crushing the crimp terminal, a cutting mechanism for cutting the wire, a feed mechanism for moving the wire to a predetermined position, and a length of the wire generated by the operation of the cutting mechanism. Length setting means, the crimping mechanism, the cutting mechanism according to a program,

Further, the wire feeding device includes a feeding mechanism that feeds an electric wire to the crimping device main body, a receiving unit that receives information transmitted from the transmitting unit of the crimping device main body, and the output unit based on an output of the receiving unit. A feeding speed determining means for determining an operating speed of the feeding mechanism.

Here, the "crimping mechanism" comprises a pressing member for pressing the crimp terminal, a power unit for vertically moving the pressing member, a base on which the crimp terminal is placed, and the like. Is to be crushed. "Cutting mechanism"
Has a blade section and a power section for moving the blade section, and cuts the electric wire by the operation of the power section. The “sending mechanism” includes a rotatable roller and a power unit for rotating the roller, and operates the power unit to feed an electric wire by the roller. The length of the electric wire to be sent can be recognized by, for example, the number of rotations of the roller. The "length setting means" is for setting the length of the electric wire to be processed, and may be set to an arbitrary length by numerical values using a numeric keypad or the like. You may make it select from setting values.
The “operation control means” has a central information processing device (CPU) that performs calculation and control, and performs various controls according to a program input in advance. The information transmission between the “transmitting means” and the “receiving means” may be performed via a signal line, or may be performed wirelessly using light or the like.

Therefore, according to the terminal crimping system of the first aspect of the present invention, in the crimping device main body, first, the length of the electric wire to be processed is set by the length setting means.
Adjustment values such as the crushing time, the wire feed speed, and the wire discharge speed are set. The transmitting means transmits information on the length of the electric wire set by the length setting means and information on a series of machining cycles by the operation control means to a receiving means provided in the electric wire feeding device. Here, the information on the series of processing cycles is the time required to generate one wire to which the crimp terminal is crimped, and the operation time in each process such as the crushing time, the wire feeding time, the wire discharging time, and the like. Is the cumulative value of. This accumulated value is calculated by the program of the operation control means,
It can be calculated based on the set adjustment value.
The transmitting means may transmit information on the length of the electric wire and information on a series of machining cycles as individual information. From these two pieces of information, the length of the electric wire used per unit time may be determined. (Electric wire length / processing cycle) may be obtained, and only the obtained electric wire length may be transmitted.

[0015] The wire feeding device has a receiving means and recognizes information transmitted from the transmitting means of the crimping device main body. Then, the feeding speed determining means of the electric wire feeding device determines the operating speed of the feeding mechanism based on the information input via the receiving means. Specifically, the feeding speed when the feeding mechanism is operated, that is, the length of the wire drawn out per unit time is determined by the length of the wire used per unit time in the crimping device body (the length of the wire). (Depth / machining cycle). When the start of the operation is instructed, the feeding mechanism operates at the thus determined feeding speed. Before the operation of the feeding mechanism is started, the tip of the electric wire is made to face the feeding mechanism of the crimping device body in advance. At this time, it is desirable that the electric wire between the electric wire feeding device and the crimping device main body is not in a stretched state, but is in a surplus state with some allowance.

When the start of the operation is instructed, the operation control means of the crimping apparatus main body operates the crimping mechanism, the feeding mechanism, the cutting mechanism and the like in accordance with a program input in advance. Specifically, the tip of the electric wire is inserted into the crimp terminal placed on the base by the wire feeding mechanism, and the crimp terminal is crushed by the operation of the power unit. Thereafter, the wire to which the crimp terminal has been crimped is fed by a predetermined length by a wire feeding mechanism and cut by a cutting mechanism. The operation by the operation control means and the operation of the electric wire feeding mechanism are started almost simultaneously. Specifically, when the operation control means starts the operation, a start signal may be sent to the wire feeding device via the transmission device and the receiving device, or the crimping device main body and the wire feeding device, Each has an operation switch,
The operator may turn on the two operation switches simultaneously.

As described above, the feeding speed of the feeding mechanism is automatically set based on the processing cycle of the crimping device main body and the length of the wire, so that the wire fed by the wire feeding device is excessively surplus. The crimping operation is continuously repeated without causing the supplied electric wire to run out.

According to a second aspect of the present invention, there is provided a terminal crimping system according to the first aspect, further comprising a transport mechanism for transporting the electric wires, wherein the conveyer has an electric wire accommodating portion formed in parallel with the conveying direction. , Disposed on the discharge side of the crimping device main body. The crimping device main body includes a discharge mechanism that clamps a rear end of the processed electric wire and discharges the processed electric wire to the wire housing portion side, and a second transmission unit that transmits information regarding a discharge speed of the discharge mechanism. . The conveyor further includes a second receiving unit that receives information transmitted from the second transmitting unit of the crimping device main body, and a transport that determines an operation speed of the transport mechanism based on an output of the second receiving unit. Speed determining means.

Here, the "conveyor" is, for example, a belt conveyor, and the electric wire can be conveyed by operating the conveying mechanism. The conveyor has an electric wire housing portion formed in parallel with the conveying direction of the conveying mechanism, and can collectively accommodate a large number of electric wires processed by the crimping device main body. The “discharge mechanism” has a function that can hold and release the rear end of the processed electric wire, a function that moves between a predetermined position in the crimping device main body, and the vicinity of the electric wire housing of the conveyor. Have. Further, information transmission between the “second transmitting means” and the “second receiving means” may be performed via a signal line, or may be performed wirelessly using light or the like.

Therefore, according to the terminal crimping system according to the second aspect of the present invention, in addition to the operation of the terminal crimping system according to the first aspect of the present invention, the second transmitting means of the crimping device main body transmits information relating to the discharge speed of the discharge mechanism. , The second provided on the conveyor
Send to receiving means.

The conveyor has a second receiving means, and recognizes information transmitted from the second transmitting means of the crimping device main body.
Then, the conveyor speed determination unit determines the operation speed of the transport mechanism based on the information input via the second receiving unit. The transport mechanism, when instructed to start the operation,
It operates at the transport speed determined in this way. The operation of the conveyor may be started at least when the crimping operation in the crimping device main body is started, and the conveying operation may be started in advance before the operation of the operation control means is started. The transport operation may be started substantially simultaneously with the start of the operation of the control means. In order to start them almost simultaneously, a start signal may be transmitted from the crimping device main body to the conveyor via the second transmitting means and the second receiving means, and the conveying operation may be started based on this signal.

When the start of the operation is instructed, the operation control means of the crimping apparatus main body operates the discharging mechanism in addition to the above-described crimping mechanism, feed mechanism, and cutting mechanism. In particular,
When the electric wire with the crimp terminal crimped to the tip is cut by the operation of the cutting mechanism, the electric wire having the length set by the length setting means is generated. At this time, the front end side of the electric wire is located on the conveyor transport mechanism. The discharge mechanism clamps the rear end side of the electric wire and moves to the electric wire housing portion side of the conveyor after the electric wire is cut. That is, the tip side of the wire is
Although the wire is to be transported in the transport direction by the conveyor transport mechanism, the rear end side of the wire is moved in the direction of the wire accommodating portion of the conveyor by the discharge mechanism, so that the discharge speed of the discharge mechanism and the transport speed of the conveyor are different. If the relationship is moderate, the wire moves (slids) obliquely with respect to the transport direction while keeping the straight line on the conveyor's transport mechanism, and the wire housing formed parallel to the transport direction. To be housed. In other words, the plurality of electric wires in a straight line are accommodated in the electric wire housing with their rear ends aligned. In the case where two crimping mechanisms are provided and have a function of crimping the crimp terminals to both ends of the wire, after the wire is cut by the cutting mechanism, the crimp terminals are crimped to the rear end of the wire and then discharged. Discharged by the mechanism.

As described above, the transport speed of the conveyor transport mechanism is determined based on the discharge speed of the discharge mechanism of the crimping device main body.
Since the setting is automatically performed, the transport mechanism operates at an optimum speed, and moves the processed electric wire to the electric wire housing portion in a straight line state.

Here, the "two-way communication means" may transmit information via a signal line, or may transmit wirelessly using light or the like. In addition, the “abnormal state” includes a failure of the wire feeding device, twisting, disconnection, wire breakage, and the like of the wire.

Therefore, according to the terminal crimping system of the third aspect of the present invention, in addition to the operation of the terminal crimping system of the first or second aspect of the present invention, the wire feeding device includes a state detecting means for detecting an operation state. When an abnormal state is detected, such as when the electric wire feeding device breaks down, a signal indicating the abnormal state is transmitted to the crimping device main body via the communication means. When an abnormal signal is transmitted from the wire feeding device, the abnormality processing control unit of the crimping device main body stops operating operations of the crimping mechanism, the cutting mechanism, the feed mechanism, and the like. Accordingly, when an abnormality occurs in the wire feeding device and the wire cannot be normally fed, the crimping operation of the crimping device main body is immediately stopped.

According to a fourth aspect of the present invention, in the terminal crimping system according to any one of the first to third aspects, the transmitting means converts an electric signal into an optical signal. And the receiving means includes a photosensitive element that converts an optical signal transmitted from the light emitting element into an electric signal.

It is converted into an optical signal (a signal based on near-infrared light) and transmitted. On the other hand, in the receiving means, the light signal is converted into an electric signal by the photosensitive element and recognized as information. Therefore, information is transmitted wirelessly.

When the end portion of the electric wire L exceeds the blade of the cutting mechanism 9 by a predetermined length, the rotation of the roller 25 is temporarily stopped, and the upper blade is moved to the lower blade side by a moving means (not shown). The gap between the blade and the lower blade has a predetermined length. In addition,

By means of 1, the holding means 30 and the feeding means 32 are moved in the direction of arrow G shown in FIG. When the wire L is moved to the second crimping mechanism 8 side, the wire L is moved in the direction of arrow H shown in FIG.
The electric wire is fed into the anvil of the crimping mechanism 8. In the second crimping mechanism 8 as well, like the first crimping mechanism 7, the crimp terminals are sequentially supplied to the anvil every time the crush operation is performed. Is inserted into.

After the rear end of the wire L is fed into the crimp terminal, the crimp terminal is crushed. That is, similarly to the first crimping mechanism 7, the electric motor of the power mechanism is driven, the pressing member moves downward together with the guide member, and the tip of the pressing member meshes with the anvil formed on the base to crush the crimp terminal.

2. Opening 61 of leg member 58a and third guide roller 7
1 is connected to the wire feeding mechanism 10 of the crimping device main body 2. That is, the electric wire fed by the feeding mechanism 60 is supplied to the crimping device main body 2 by the operation of the wire feeding mechanism 10 of the crimping device main body 2.

The feed-out control means 66 of the feed-out mechanism 60 is arranged as shown in FIG.

And state detecting means 74 for transmitting the data via

On the other hand, the control means 38 of the crimping device main body 2 has a first communication control section 51 corresponding to the feeding control means 66.
And the processing cycle of the crimping device main body 2 and calculate the information as the first
The processing cycle calculation unit 75 to be sent to the communication control unit 51 and the information on the wire length set by the wire length setting unit 42 are stored in the first
A length information recognizing unit 76 to be sent to the communication control unit 51; an abnormal stop unit 77 for stopping the operation of the crimping device main body 2 when an abnormal signal is input from the electric wire feeding device 4 via the first communication control unit 51; Is provided. Here, the processing cycle is the time required for processing a single electric wire by a series of operations in the crimping device main body 2, and each of the wire feeding mechanism 10, the first crimping mechanism 7, the cutting mechanism 9, and the like. This is the cumulative value of the operation time.
However, as described above, in the crimping device main body 2, the electric wire L
Since the operation of crimping the crimp terminal to the front end side of the wire and the operation of crimping the crimp terminal to the rear end side of the electric wire L are performed in parallel, the above cumulative value is the sum of the operation times of all the mechanisms. is not. As described above, the first communication control unit 51 transmits information on the processing cycle and information on the length of the electric wire. When transmitting these two pieces of information to the third communication control unit 53, they may be transmitted as individual information. However, based on the length of the wire L to be machined and the machining cycle, the number of wires used per unit time is determined. The length may be obtained (wire length / processing cycle), and the obtained wire length may be transmitted as information.

In the feeding control means 66 of the electric wire feeding device 4,
The wire feeding speed is determined based on the information thus sent. Therefore, the length of the electric wire L generated by the crimping device main body 2 and the length of the electric wire L fed out by the electric wire feeding device 4 while one of the electric wires L is processed can be made to substantially match. That is, when the operation of the electric wire feeding mechanism 10 is stopped, such as during the operation of the first crimping mechanism 7, the electric wire L is not used in the crimping device main body 2, so the electric wire L fed out by the electric wire feeding device 4 is excessive. Becomes
The wire L for the length set by the wire length setting unit 42
When the wire is sent by the wire feed mechanism 10, the surplus wire L is supplied. When a plurality of electric wires L are continuously processed, the surplus of the electric wires L and the use of the electric wires L are repeated. In the present embodiment, the feeding speed of the electric wires L is determined by the information sent from the crimping device main body 2. Therefore, the operation of the crimping device main body 2 does not stop because the supplied electric wire L is not excessive or conversely, the supplied electric wire L is insufficient.

The conveyor 5 is a belt conveyor that conveys the electric wires placed on the belt 80, and is disposed on the discharge side of the crimping device main body 2 as shown in FIGS. The conveyor 5 includes an electric motor 81 (see FIG. 7) whose rotation axis rotates in a fixed direction, and a pulley (not shown) that rotates by the electric motor 81 and rotates the belt 80 in the transport direction. Note that the electric motor 80 is
(See FIG. 7). On the side of the conveyor 5, an electric wire housing 82 is formed in parallel with the transport direction. The wire accommodating portion 82 is formed by bending the side wall of the conveyor 5 into a substantially U-shaped cross section, and is formed at a position lower than the upper surface of the belt 80.

By the cooperation of the conveyor 5 and the above-described discharge mechanism 12 of the crimping device main body 2, the electric wire L processed by the crimping device main body 2 is conveyed to the wire accommodating portion 82 in a straight state. That is, in the state where the crimp terminals are crimped to both ends of the wire L in the crimping device main body 2, the front end of the wire L is located on the belt 80 of the conveyor 5, and the rear end of the wire L is holding the discharging mechanism 12. It is sandwiched between members 37. In this state, when the movable member 35 of the discharge mechanism 12 is moved toward the wire accommodating portion 82 of the conveyor 5, the leading end side of the wire L tends to be transported by the belt 80 of the conveyor 5 in the transport direction. Is moved in the direction of the wire accommodating portion 82 of the conveyor 5 by the discharging mechanism 12, so that if the relationship between the discharging speed of the discharging mechanism 12 and the transport speed of the conveyor 5 is an appropriate relationship, the electric wire L Is moved (slid) in an oblique direction with respect to the transport direction while being kept in a straight line on the belt 80 of the conveyor 5, and is accommodated in an electric wire accommodating portion 82 formed in parallel with the transport direction. Thereby, when the electric wires L are continuously processed, the plurality of electric wires L are accommodated in the same position of the electric wire accommodating portion 82 in a straight line state. Here, the belt 80,
The pulley and the electric motor 81 correspond to the transport mechanism of the present invention.

As shown in FIG. 7, the transport control means 83 of the conveyor 5 includes a fourth communication control unit 54 for performing bidirectional communication with the second communication control unit 52 of the crimping device main body 2, and a fourth communication control unit A conveying speed determining unit 84 that determines the conveying speed of the electric wire L by the belt 80 of the conveyor 5 based on the information input via the communication control unit 54, and the belt 80 is driven by the conveying speed determined by the conveying speed determining unit 84. Electric motor 81 to rotate
And a state detecting means 86 for detecting an operating state of the conveyor 5 and transmitting an abnormal signal via the fourth communication control section 54 when the conveyor 5 is in an abnormal state.

On the other hand, the control means 38 of the crimping device main body 2 has a second communication control section 52 corresponding to the transport control means 83.
A discharge speed recognizing unit 87 that sends information on the discharge speed of the discharge mechanism 12 set by the adjustment value setting unit 41 to the second communication control unit 52; and the above-described abnormal stop unit 77.
As described above, the second communication control unit 52 transmits information on the ejection speed to the fourth communication control unit 54.

The conveyor control means 83 of the conveyor 5 determines the conveyor speed of the conveyor 5 based on the information thus sent. Specifically, the relationship between the discharge speed of the discharge mechanism 12 and the corresponding optimum value of the transport speed of the conveyor 5 is recognized in advance by a test or the like.
Is stored as a data table in the transport speed determining means 84. The transport speed determining means 84 determines the optimal value of the transport speed of the conveyor 5 based on the stored data table and the transmitted information. As described above, since the conveyor speed of the conveyor 5 is automatically set, the belt 80
Operates at an optimum speed, and can move the processed electric wire to the electric wire accommodating portion 82 in a straight line state.

Next, the control means 3 in the crimping device main body 2
8 will be described, in particular, control relating to communication.
When the length of the electric wire L is set by the electric wire length setting unit 42 and the adjustment value of the operation time in each mechanism such as the crimping time and the discharging time is set by the adjustment value setting unit 41, the first communication control unit 51 Information on the processing cycle of the crimping device main body 2 and information on the length of the electric wire are transmitted to the third communication control unit 53 (step S1). Also, the second communication control unit 52
Is transmitted to the fourth communication control unit 54 (step S2). Thereby, the feeding control means 66 of the wire feeding device 4 and the conveyance control means 83 of the conveyor 5 determine the feeding speed of the wire by the feeding mechanism 60 and the speed of the belt 80 based on the information sent from the crimping device main body 2. The respective transport speeds are determined, and driving is started.

During operation (during wire processing), the wire feeding device 4
Alternatively, when an abnormal state occurs in the conveyor 5, an abnormal signal is transmitted from the third communication control unit 53 or the fourth communication control unit 54. Therefore, in the crimping device main body 2, when an abnormal signal is transmitted from the third communication control unit 53 (NO in step S3), or when an abnormal signal is transmitted from the fourth communication control unit 54 (NO in step S4). Then, the operation of the crimping device main body 2 is stopped. Third communication control unit 5
If no abnormal signal has been transmitted from the third or fourth communication control unit 54, the process proceeds to step S6. In step S6, it is determined whether or not the processing cycle of the crimping device main body 2, the length of the wire L, the discharge speed of the wire L, and the like have been changed, and if they have been changed (YES in step S6), step S1. And the information is transmitted again to the wire feeder 4 and the conveyor 5. If it has not been changed (NO in step S6), the process returns to step S3, and monitoring is continuously performed to determine whether an abnormal signal is transmitted from the wire feeding device 4 or the conveyor 5.

As described above, in the terminal crimping system 1 described above, the wire feeding device 4 uses the information on the processing cycle of the crimping device main body 2 transmitted from the crimping device main body 2 and the information on the length of the wire to be processed. In order to determine the feeding speed of the feeding mechanism 60 based on the speed, the speed of the wire to be fed out, in other words, the length of the wire to be fed out per unit time is automatically set to an optimal value. Is set. Therefore, continuous operation can be started quickly without performing the operation of adjusting the feeding speed. In addition, since the value is set to an optimal value, an excessive amount of electric wire is left between the wire feeding device 4 and the crimping device main body, or the operation of the crimping device main body 2 is stopped due to a shortage of the wire to be fed. Nothing.

In the terminal crimping system 1 described above, the conveyor 5 is provided with the discharging mechanism 1 transmitted from the crimping device main body 2.
2, the conveyor speed of the conveyor 5 is determined and automatically adjusted. Therefore, the operator can start the operation of the crimping device main body 2 without adjusting the transport speed. Further, since the conveying speed of the conveyor 5 is set to the optimum speed, the processed electric wire can be discharged to the electric wire housing portion 82 without being bent, and the electric motor 81 can be rotated at an unnecessarily high speed. Therefore, power consumption can be reduced as much as possible.

Further, in the terminal crimping system 1 described above,
Bidirectional communication is performed between the crimping device main body 2 and the wire feeding device 4 or between the crimping device main body 2 and the conveyor 5;
When an abnormal state occurs in the wire feeding device 4 or the conveyor 5, the operation of the crimping device main body 2 is stopped immediately, so that safety is improved and occurrence of defective products can be minimized.

Further, in the terminal crimping system 1 described above,
Since light is used as a means for transmitting information and wireless communication is performed, the signal line does not hinder the work, and the operator does not get caught on the signal line and break the signal line. Therefore, safety is high.

By the way, in the terminal crimping system 1 of the above-described embodiment, a system in which light is used as the information transmitting means to perform wireless communication has been described, but information may be transmitted through a signal line. In the terminal crimping system 1 of the above-described embodiment, a system that performs two-way communication has been described. However, only information is transmitted from the crimping device main body 2 to the wire feeding device 4 or from the crimping device main body 2 to the conveyor 5. It does not matter.

In the terminal crimping system 1 of the above embodiment,
Although the conveyor 5 is arranged on the discharge side of the crimping device main body 2, the conveyor 5 may not be provided as long as the processed electric wire can be accommodated on the crimping device main body 2. In the terminal crimping system 1 of the above embodiment, the crimp terminal is crushed at both ends of the electric wire L. However, the crimp terminal may be crimped only to the end of the electric wire L.
