Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an aligning and winding device for automatically and orderly winding electric wires, hoses, and other wire rods on a winding drum.

[0002]

[Prior Art]

 When winding wire rods such as electric wires and hoses, in order to wind them in order, the wire rod immediately before entering the winding drum is sequentially folded back to the right by the traverser with the guide member to move the entry position. . All of the traverse mechanisms are configured to drive the traverser, reverse traverse pitch adjustment, etc. mechanically using a transmission motor, a forward / reverse clutch unit, etc. from a take-up motor that rotates a winding cylinder.

FIG. 4 shows the conventional traverse mechanism. The power of the take-up motor 1 works in two systems, that is, the rotational drive of the winding cylinder 2 and the reciprocating drive of the traverser 5. That is, while the winding drum 2 attached to the winder 7 is rotationally driven by the motor 1, the speed reducer 1a, and the chain wheels 6 and 6, the pulleys 8 and 8, the transmission 3, the chain wheels 9 and 9, and the forward and reverse rotations. The clutch unit 4 turns the drive screw 10 that causes the traverser 5 to reciprocate.

The transmission 3 is manually adjusted in advance so that the drive screw 10 that rotates in conjunction with the winding drum 2 moves the traverser 5 laterally by one pitch (a diameter of the wire approximately) while the winding drum 2 rotates once. Keep it in order. In order to adjust the traverser swing width S to the width of the winding drum 2, the left and right inversion position detection sensors 11 and 11 are manually operated so that the guide wheel 5a of the traverser 5 is inverted at a position corresponding to the end of the winding drum 2. Then, the command is given to the forward / reverse rotation unit 4.

[0005]

In the conventional traverse mechanism for aligning and winding, the power source of the traverse mechanism and the traverser driving screw are made to be one winding motor in order to completely interlock the winding drum and the traverser driving screw. However, this mechanical interlocking method involved many parts and required maintenance, and the preparation for winding was troublesome. However, since it was difficult to make fine adjustments, even if the winding was a little uneven, there was no way to deal with it. This device addressed the fundamental improvement of the above problems.

[0006]

[Means for Solving the Problems]

 The wire rod aligning and winding apparatus according to the present invention includes a winding motor that rotationally drives a winding cylinder, a servo motor that reciprocally rotates a traverse drive screw, and a servo motor control each time the winding cylinder makes one rotation. To the position of the traverser to advance the traverser by one pitch, and when the traverser comes to the starting point position where the wire rod is fed to one end of the winding cylinder, or when it comes to the position at a constant distance from it. It is characterized by being provided with an origin sensor for detecting and transmitting as the origin of the traverser. On the operation panel connected to the control section of the servomotor, the winding width of the winding drum and the diameter of the wire rod are set, and the traverse pitch and traverser swing width per rotation of the winding drum obtained from the set values. Is provided, a fine adjustment unit for each direction of the pitch, and a traverser origin return command button.

[0007]

[Action]

 This invention eliminates the conventional fixed concept that the winding drum and the traverser drive screw should be interlocked. Instead of interlocking, the traverser drive screw is driven intermittently by a servo motor. If the site worker sets the winding width of the winding drum and the diameter of the wire rod on the operation panel connected to the control section of the servo motor, the traverse pitch and traverser swing width are automatically determined from the set values. If you press the return-to-origin command button and then press the start button, the traverser moves by the required traverse pitch for each revolution of the winding cylinder, and the reversal is repeated at the required swing width to proceed with winding. When winding is likely to be a problem due to the bending tendency of the wire, the traverse pitch is finely adjusted by the fine-tuning section for each traveling direction.

【Example】

 FIG. 1 shows an embodiment of this invention. The winding motor 1 and the speed reducer 1a rotate and drive the winding drum 2 attached to the winding machine 7 via the chain wheels 6 and 6 as in FIG. Each time the pulse plate 12 a and the sensor 12 b of the winding cylinder rotation angle detection device 12 mounted coaxially with the winding cylinder 2 emit a pulse for one rotation of the winding cylinder 2, the servomotor 13 turns the pulleys 14 and 14 on. The drive screw 10 is turned through to move the traverser 5 by a required pitch. In this embodiment, the origin sensor 15 is arranged at the starting point of the lateral movement of the traverser 5. The swing width S of the traverser 5 is from the origin to the reverse position. It is a well-known technique that the inversion command is issued when the internal pulse of the servo motor 13 reaches the number corresponding to the swing width S.

FIG. 2 shows a relationship between the winding drum 2 and the wound wire rod C. P is the traverse pitch, and the allowance α is added to the diameter d of the wire C. An integral multiple of the pitch P does not make up the width W of the winding cylinder, leaving a gap of β. This β is a lap gap that is indispensable for winding the wire C in a trough, and because it exists, it can be wound naturally in the trough as shown in Fig. 2 simply by reciprocating the traverser 5. .

FIG. 3 shows an example of an operation panel placed at the site worker. This is the operation panel for the entire winder, but the lower half is for servo motor control. Other than the numeric keypad 16 at the left end of the figure, the relevant parts are named. The "roll width" is the roll width display on the reel, and you can press the attached button on the left and press the numeric keypad 16 to set a numerical value on the 4-digit display surface. Similarly, set the diameter of the wire to be wound under "Wire diameter" and display it.

When the “winding width” and the “wire diameter” are set, the “amplitude” and the “pitch” of the traverser are automatically displayed. “Left pitch” and “right pitch” are divided by direction because even if the initial value is the same, the operator finely adjusts it due to the bending tendency of the wire. "Left line pitch" "Right line pitch" There is an increase / decrease button on the left side of each display surface, which increases or decreases by 0.1 mm when pressed once. The "Origin" on the left side of the "Amplitude" display surface is the return-to-origin command button that is pressed when returning the traverser to the origin. The “current value” at the right end indicates the amount of movement of the amplitude from the starting point. “Data No.” is a number of specific numbers that is a set of winding width and wire diameter, and eliminates the need to set numerical values.

When the "winding width" and "wire diameter" are set during operation and the "origin" button is pressed, the traverser 5 uses the origin sensor 15 of FIG. 1 to detect the swing width S, which is the origin. Stop at the starting point. Then, when the start button is pressed, the winding starts, the pulses sent by the pulse plate 12a and the sensor 12b are counted, and when one rotation is made, the servo motor 13 advances the traverser 5 by one pitch. In FIG. 1, in the middle of the second winding, the traverser 5 automatically moves backward when the swing width S advances from the starting point, and reverses again when returning to the starting point.

Next, a mechanism will be described in which the traverse pitch P and the swing width S are automatically determined and displayed by setting the “winding width” and the “wire diameter”, that is, W and d in FIG. Theoretically, it seems that the pitch P may be the same as the wire diameter d, but in reality, the allowance α = (1/10 to 1/5) d is required. In addition, as shown in FIG. 2, in order to wind the wire rods C in a stack, a lap gap β = (1/2 to ¼) d is required. From these conditions, as is apparent in FIG. 2, where n is an integer, W-β = n · p, that is, W− (1/2 to 1/4) d = n · {d + (1/10 to 1/1 5) d} Therefore, W- (0.25 to 0.5) d = n · (1.1 to 1.2) d.

As an example, when the winding width is W = 715 mm and the wire diameter is d = 15 mm, the following four values satisfy the above equation. (N) (p) (α) (β) (S) 43 709.5 1.5 5.5 5.5 694.5 42 709.8 1.9 5.2 694.8 41 709.3 2.3 5. 7 694.3 40 708.0 2.7 7.0 696.0

The larger the number of turns n, the smaller the allowance α and the overlapping gap β, but empirically, the optimum one should be stored in advance, or the allowance α = (1/10 to 1/1 / 5) With d, it is possible to narrow down and specify P and S in each calculation. As a simple method, if (α = 0, β = d) and (p = d, S = W-2d) are set, (p = 15, S = 685) will be displayed on the operation panel in the above example. You can also make a fine adjustment while watching the winding condition and add the necessary α to p = 15. It is needless to say that the embodiment of the present invention can be variously changed and applied by the well-known technique of the mechanical designer other than the above-mentioned one.

[Effect of the device]

 This invention abandoned the conventional wisdom that the traverser of the wire winding device is interlocked with the winding motor, and opened a new method of moving and reversing the servo motor whenever necessary. Not only was this device significantly simplified and complicated winding preparation work due to mechanical interlocking and the troublesome winding preparation work, but the traverse pitch on the operation panel was adjusted even during winding. Fine adjustments were made in the direction of travel so that problems due to the bending tendency of the wire rod and other problems can be addressed.
