Description

  The present invention relates to an electric wire processing apparatus and a method for performing processing such as length measurement, cutting, insulation coating peeling, terminal crimping, and the like of a small variety of electric wires.

  Conventionally, there are two methods for processing a small number of types of wires. One is the automatic processing of the process from measuring the length of the wire to cutting, peeling off the insulation coating, and crimping the terminal. There is a method in which all the processes from the insulation coating peeling to the terminal crimping are performed manually one by one.

  [Patent Document 1] includes a database in which wire types, processing order, and processing information are described for a plurality of electric wires to be processed, automatic cutting means for cutting the electric wires and peeling off the insulation coating at both ends, and this automatic A work table arranged together with a machining tool that requires a plurality of work spaces for sequentially performing different machining operations on the electric wires cut by the cutting means, and a machining operation arranged corresponding to the work space and performed in each work space A display terminal for displaying the machining information, a switch means for inputting the end of the machining operation for each work space, and the next to each display terminal with reference to the database based on the machining work end signal input from the switch means.

JP 2005-32540 A

  When all the operations are performed manually, the operator must read necessary information from a lot of information described in the drawings and lists, and it takes time to read the drawings. In addition, because drawings and lists contain information necessary or unnecessary for production, it may cause a determination error, resulting in poor production efficiency.

  Moreover, since a scale is used for measuring the electric wire and cutting is performed using a nipper, there is a problem that each operation takes a lot of time. In addition, when work requiring know-how occurs, it is necessary to search various related documents and information, and there is a problem that quality varies.

  On the other hand, when processing small quantities of various types of wires using equipment without human intervention, there are limits to the types of wires and terminals that can be set in advance. When this occurs, there is a problem that it takes a lot of time to change the setup. In addition, there is a problem that the apparatus is large and expensive.

  In the electric wire processing management device described in [Patent Document 1], each time when each manual operation is completed in electric wire processing, the button is pressed to display the processing information of the next electric wire to be processed on the display terminal, and the electric wire processing operation is sequentially performed. However, the automatic cutting unit sets the wire bundle of the electric wire, and the wire end processing is selected from a plurality of types of crimping tools placed on the workbench. A crimping tool is used to attach the crimping terminals at both ends of the electric wire, and the marker is peeled off from the mount and attached to the electric wire.

  In such conventional wire processing, there is a shortage of one or several types of wires that can be set. Every time an unset wire is processed, an operator must bundle a bundle of wires in a cage or the like. It took a lot of time each time the type of the wire to be processed was switched to take out and set the next bundle of wires. In addition, there is a problem that quality variations such as crimping leakage of terminals and wrong terminals occur. In addition, since the marker must be peeled off from the mount, the work time for attaching the marker cannot be shortened.

  A first object of the present invention is to provide an electric wire processing apparatus that shortens the time required for changing wires and terminals and improves production efficiency in an electric wire processing line including manual work.

  A second object of the present invention is to provide an electric wire processing apparatus that reduces the time required to retrieve and read drawings and lists in an electric wire processing line including manual work, thereby improving production efficiency.

  A third object of the present invention is to provide an electric wire processing apparatus that can perform work without relying on know-how even in work that requires know-how in an electric wire processing line that includes manual work, and that has little variation in quality. is there.

  In order to achieve the above object, an electric wire processing apparatus according to the present invention is installed in an electric wire changer device in which each of a plurality of bobbin wound electric wires is placed on a fixed pulley and a pulley with a weight, and the electric wire changer device. An automatic cutting device that sets an electric wire, cuts the electric wire at a specified length and performs a peeling process, a crimping device with a lamp that performs end treatment on both ends of the electric wire cut by the automatic cutting device, and a terminal treatment by the crimping device Automatic marker feeder that holds the marker to be attached to the electric wire in a state where one end is peeled off from the mount, and processing information related to the automatic cutting device, crimping device and marker automatic feeder by pressing the push button The display terminal is provided.

  In addition, the wire processing method displays the information about the wire on the display terminal and automatically cuts the wire installed in the wire changer device where each of the bobbin-wound wires is placed on a fixed pulley and a pulley with a weight. Set on the device, cut the wire to the specified length and peel it off, display the type of crimp terminal on the display terminal, end treatment of both ends of the wire cut by the crimping device with the lamp lit The marker information is displayed on the display terminal, the marker is peeled off from the automatic marker feeding device that holds the marker in a state where one end is peeled off from the mount, and the marker is pasted on the terminal-treated electric wire.

  According to the present invention, in electric wire processing including manual work, the type of electric wire to be processed can be quickly switched, and the production efficiency can be improved.

  Moreover, in the electric wire processing including manual work, an apparatus capable of performing stable quality electric wire processing can be realized at low cost regardless of the skill level of the operator.

  An electric wire processing apparatus according to an embodiment of the present invention will be described with reference to FIGS.

  An electric wire processing apparatus is an apparatus which processes the electric wire which connects between the apparatuses mounted in a switchboard, a control panel, etc. As shown in FIG. 1, the wire processing device is an automatic wire cutting device 1 that mainly stores a plurality of wires, and an automatic wire cutting device that automatically cuts the wires installed on the work table 24 at the rear stage of the wire changing device 1. Of the cutting device 8, the display terminal 11 which is provided in the subsequent stage of the automatic cutting device 8 and displays the processing information, the management terminal 25, the wire cradle 13, the push button 14 for transmitting the work signal, and the push button 14 It comprises an automatic crimping device 16 that performs terminal processing of electric wires installed in a subsequent stage, and an automatic marker feeding device 23 that automatically sends a marker.

  As shown in FIG. 2, the wire setup changing device 1 includes a bobbin 2 around which a wire rotating around a shaft 3 as a rotation axis, a plurality of fixed pulleys 6 fixed to an upper end portion, and an intermediate between the fixed pulleys 6. And a pulley 5 with a metal weight 4 that moves up and down along a fixed guide 10 and a spring 7 that is provided at the end and clamps and holds an electric wire.

The bobbin 2 is installed in the upper part of the wire setup changer 1 as necessary for the production of the product. In the example shown in FIG. 2, the electric wire wound around the bobbin 2 is hooked on the pulley 5a, the fixed pulley 6a, the pulley 5b, the fixed pulley 6b, the pulley 5c, and the fixed pulley 6c and sandwiched between the springs 7. The weight 4 is adjusted so that the electric wire can be drawn from the bobbin 2 at an appropriate speed depending on the type of the electric wire.

  A wheel 25 is provided in the lower part of the wire setup changer 1 so that the bobbin 2 can be appropriately installed by being moved.

  As described above, the electric wire setup changing device of the present embodiment can store many electric wires and can be manufactured at low cost because it does not use power such as rotating a bobbin for supplying electric wires with a simple structure. In addition, the time required for changing the wires can be shortened.

  When starting the wire processing management device (not shown), the control unit refers to the database via the network, acquires processing information of the processing target wire, and when starting the wire processing device, information on the wire to be processed on the display terminal 11, That is, a list in which the types of wires, wire lengths, wire diameters, etc. are arranged in the order of processing is displayed. An arm 12 is attached to the display terminal 11 so that the display terminal 11 can be freely moved up, down, left and right with respect to an operator.

  The operator looks at the information displayed on the display terminal 11, confirms the bobbin 2 installed in the electric wire changing device 1, and sets the electric wire to be cut next in the automatic cutting device 8.

  When the push button 14 is pressed in a state where the electric wire is set, information on the type of electric wire, the length of the wire, and the coating peeling dimension is displayed on the display terminal 11, and the electric wire to be processed is cut at a specified length. At this time, the insulating coatings at both ends of the cut electric wire are automatically controlled according to the processing conditions of the electric wire and stripped.

  When the electric wire is cut, the electric wire is pulled by the roller 9 that rotates at high speed. Since the bobbin 2 is heavy, there is inertia and the rotation speed of the bobbin does not follow the pulling of the roller 9, but the weight 4 of the electric wire changer 1 temporarily rises along the guide 10 and feeds the electric wire with the extra length. The electric wire can be sent out following the rotating roller 9 of the automatic cutting device 8.

  When the roller 9 stops after the cutting is finished, the weight 4 descends by weight and pulls the electric wire, so that the bobbin 2 rotates slowly and the electric wire is pulled out from the bobbin 2. The pulley 5 with the weight 4 descends to the original position and returns to the state before the wire is cut. During this time, the automatic cutting device 8 cannot operate, but it is within the time for processing in other processes and does not cause any trouble.

  When the weight 4 is raised, the electric wire is tensioned by the weight 4, but the tension is adjusted so as not to affect the quality and length measurement of the electric wire. Further, since the maximum surplus length of the electric wire processed by the electric wire processing device is secured from the bobbin 2 to the automatic cutting device 8, a large tension is directly applied to the automatic cutting device 8 due to the rotation of the bobbin 2. There is no.

When the electric wire is cut by the automatic cutting device 8, the cut electric wire is discharged to the electric wire cradle 13. After confirming that the electric wire has been discharged to the electric wire cradle 13, when the operator presses the push button 14 again, the display terminal 11 displays the type of the crimp terminal, which is processing information for the next process, by this signal. Is done.

  The worker performs an operation of performing terminal treatment on both ends of the electric wire discharged to the electric wire cradle 13. The automatic crimping | compression-bonding apparatus 16 for performing the terminal process of an electric wire is selected from several types.

  An LED lamp 18 is attached to the upper part of each automatic crimping device 16, and the LED lamp 18 is provided with a lamp indicating a crimping device used for processing the tip of the electric wire and a lamp indicating a crimping device used for processing the rear end of the electric wire. ing. This lamp is lit on each crimping device even when different crimping devices are used.

  In this way, the lamp of the crimping device to be used next can be turned on, and the automatic crimping device 16 whose lamp is lit can be selected to perform front end processing and rear end processing. Since it can be seen at a glance, even if the user is not familiar with the working method, the work can be done quickly, and the time for selecting the crimping device can be shortened. In addition, it is possible to reduce crimping leakage of terminals and incorrect crimping of terminals, and to eliminate quality variations such as terminal mistakes. Since a person performs the setting and starting operation of the electric wires, the line can be constructed with an inexpensive and small-sized apparatus that performs a crimping operation. Therefore, it is possible to install crimping apparatuses for the types of crimp terminals 15.

  In addition, adjacent to the automatic cutting device, an automatic crimping device having a function of crimping an electric wire that has been cut and the insulation coating on both ends is peeled off is arranged corresponding to the number of types of crimp terminals required. Therefore, it is possible to eliminate the time required for the terminal changeover.

  A sensor 17 for detecting the hand holding the electric wire is attached to the front surface of each automatic crimping device 16. On the floor, a foot-operated switch 19 common to a plurality of automatic crimping devices 16 is provided.

  When the step switch 19 is operated, the sensor 17 senses the crimping device on which the electric wire is set, and the crimping operation is performed by the sensed crimping device. When the crimp terminal 15 is attached to both ends of the electric wire and the terminal processing of the electric wire is completed, the operator presses the push button 14 to display information on the marker 20 to be attached to the electric wire as the next process on the display terminal 11. The marker 20 describes a terminal number of a device for wiring the wire.

An operator sends an electric wire to the marker attachment process in which the marker automatic feeder 23 is installed in order to attach the marker 20. The marker automatic feeding device 23 holds the marker 20 attached to the mount 21 in a state where one end is peeled off from the mount 21 so that the marker 20 is easily peeled off. It has become.

  In this way, by automatically sending the terminal number of the wiring destination to be attached to the electric wire with the terminal crimped, in order of processing, the search time for parts is reduced and the travel time is provided in the vicinity of the automatic crimping device. The working time can be shortened.

  When the operator presses the push button 14 after attaching the marker 20 to the electric wire, the display terminal 11 displays the electric wire type, the wire length, and the sheath peeling dimension of the electric wire to be processed next. The above steps are repeated.

  According to the present embodiment, the electric wires to be processed can be sufficiently stored, and one end of all the electric wires to be processed is fastened to the spring 7 of the electric wire changing device 1, so that even when the type of electric wires is switched. By removing the electric wire from the roller 9 of the automatic cutting device 8 and hooking it on the spring 7 and setting the next electric wire to be processed on the roller 9, the work of carrying a bundle of electric wires does not occur, and the electric wire can be changed. It can be carried out.

  In this way, only processing information necessary for each operation is displayed on the display terminal, and the processing information matches a database held by the design department with a database that has know-how such as the insulation coating peeling dimensions. By doing so, processing information such as line type and crimping terminal is displayed in the order of the process without making a person for each work execution. For this reason, it is possible to shorten the time required for the operator to search for related information and read the drawing.

  In addition, by pressing the push button 14 every time the work performed in each step of wire processing is completed, the processing information of the wire to be processed next is collected and displayed on the display terminal, and production instructions are given according to the work procedure. Since it is displayed, even if the operator has no know-how, the wire can be processed according to the displayed processing information.

  In addition, the device installed in the work space where the work of each process is performed can be configured with a single function and a small device, and the devices necessary for wire processing can be arranged in high density and three-dimensionally. Become. In addition, the crimping device can be configured with a single function and a small device, and the arrangement angle and number of the crimping devices can be freely changed, so that even when products using electric wires are changed, it is possible to respond flexibly. Moreover, since the arm 12 is attached to the display terminal 11 and the display terminal 11 can be freely moved up and down and left and right with respect to the worker, the walking time for movement for performing each element work can also be shortened. .

It is a perspective view which shows the structure of the electric wire process management apparatus which is one Example of this invention. It is a longitudinal cross-sectional view of an electric wire setup change apparatus.
