Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a take-up type wire winding machine for winding a wire from a wire processing machine such as a wire drawing machine in a coiled form.

[0002]

2. Description of the Related Art In a conventional take-up type wire winding machine, as shown in FIG. 5, a wire W is wound on a winding drum 1 which is driven to rotate, and the wire W slides down the surface of the winding drum 1. As a result, a wire bundle T that falls around the carrier 2 underneath and forms a coiled form is formed.

[0003] In this case, since the wires W only fall and stack in order, the wires W are not packed in a dense state, and the space factor, which is the ratio of the actual volume of the wires W to the volume of the wire bundle T, is low. . This is particularly noticeable when driving at high speed.

FIG. 6 shows a take-up type wire rod winding machine capable of winding into a winding shape having a high space factor. This means that the winding drum 1 is rotatably driven to take up the wire W, an elevating arm 3 provided on the winding drum 1 so as to be movable up and down, and on which the wound wire W is placed, and an elevating arm 3 being moved up and down. lift device
(Not shown), and a carrier 2 for receiving the wire bundle T from the lifting arm 3 is disposed below the winding drum 1. The winding drum 1 is formed by integrating a winding block 4 and a lower storage block 5, and the storage block 5 has a smaller diameter than the winding block 4.

During the winding operation, the wire W sent from the wire drawing machine or the like is first wound once by the winding block 4, slides down from the winding block 4 to the wire storage block 5, and falls on the lifting arm 3. It is placed and stored. The winding drum 1 is provided with a mirror 6 for detecting the stored dose, and irradiates light to the mirror 6 by an optical sensor.
The stored dose is detected based on the presence or absence of reflected light. When a certain amount of wire W is stored in the lifting arm 3, the lifting arm 3 is lowered by a certain amount, and the wire W is stored again.

At this time, as shown in FIG. 7, the wires W are densely stacked on the lifting arm 3 to form a coil-shaped wire bundle T having a high space factor. The average winding coil diameter of the wire bundle T is the same as the diameter D of the winding block 4.

When the lifting arm 3 is lowered to a position below the winding drum 1, the rotation of the winding drum 1 is stopped, and the wire W is cut. By the lifting arm 3 being folded,
The wire bundle T falls and is received by the carrier 2.

[0008]

In the above-mentioned take-up type wire rod winding machine, since the diameter of the storage line block is smaller than the diameter of the winding block, the average winding coil diameter of the wire bundle formed around the storage line block. Cannot be larger than the diameter of the winding block. Therefore, it is difficult to increase the volume of the wire bundle.

In other words, since the winding block and the storage block are integrated, the average winding coil diameter in the storage block is the same as the coil diameter in the winding block. Accordingly, an object of the present invention is to provide a take-up type wire winding machine in which the average winding coil diameter is larger than the diameter of the winding block and can be freely changed.

[0010]

Means for Solving the Problems A means for solving the problems according to the present invention is a winding block that is driven to rotate to wind a wire, a rotatable supporter disposed below the winding block, and a larger diameter than the winding block. A storage wire block, a loading arm that can be moved up and down to place a wire wound by the storage wire block with a diameter larger than the diameter of the winding block, and the loading arm below the storage wire block. A carrier for receiving the upper wire bundle, a transmission member for transmitting a driving force from the carrier that is rotationally driven to the storage block, and a transmission of the driving force from the carrier to the storage block by moving the transmission member And a moving means for cutting off.

Thus, regardless of the size of the storage block, the winding speed of the wire is the same as the rotation speed of the winding block, and the wire is stored in the storage block with an average winding coil diameter larger than that of the winding block. can do.

If the storage block is detachably attached to the winding block, the storage block can be replaced with a storage block having a different diameter. For example, by replacing the storage block according to the size of the carrier, efficiency can be improved. Good winding is possible. At this time, since the driving force is transmitted from the rotating carrier to the wire storage block by the transmission member, the storage block may be separated from the winding block.

[0013]

And a moving means for moving the carrier 15 to cut off the transmission of the driving force from the carrier 13 to the wire storage block 11 and separating the wire storage block 11 from the carrier 13.

The take-up block 10 is formed of a cylindrical drum having an outer peripheral surface with a diameter D1 and is fitted on a rotating shaft 16 of the main body frame. When the rotating shaft 16 is driven by the motor, the winding block 10 rotates.

The wire storage block 11 has a diameter D2 (D2> D
The upper surface 11a and the lower portion 11b are inclined surfaces facing the center, respectively. In particular, the diameter of the lower end of the inclined surface of the lower part 11b is
3 so that the wire W can move smoothly when the wire W slides down from the storage wire block 11 to the carrier 13. In addition, the storage line block 11
A ring 17 of the same diameter as the outer peripheral surface is
8 to prevent the wire W from entering the inclined surface of the upper portion 11a.

The wire storage block 11 is attached to a support 20 disposed at the center in the inside via a support rod 21, and a central shaft 22 of the support 20 is fixed to the winding block 10. 23, the wire storage block 11 is suspended from the winding block 10. The storage block 11 is configured such that the inclined surface of the upper part 11a and the lower part thereof can be separated, and by replacing the lower part, the diameter D2 of the outer peripheral surface is changed according to the size of the carrier 13. Can be changed.

The support rod 21 is swingably supported by a shaft 25 provided on the projecting piece 24 of the support 20, and the outer end of the support rod 21 is attached to a reinforcing rib 26 on the inner side of the wire storage block 11. 27 so as to be rotatable. Support 2
The disk 28 is fitted into the center cylinder 22 of the cylinder 0 so as to be vertically movable,
The inner end of the support rod 21 is rotatably fitted on a shaft 29 attached to the disk 28.

A ring-shaped flat plate 30 is provided below the disk 28.
The fixed body 32 is fitted into a central hole of the fixed body 32 via a bearing 31.
2 is supported so as not to rotate. A spring 33 is interposed between the flat plate 30 and the support 20 to urge the flat plate 30 downward.

Therefore, as shown in FIG.
The disk 28 is moved downward by the urging force of the above, the support rod 21 rotates counterclockwise, and the wire storage block 11 is raised. At this time, the inclined surface of the upper part 11 a of the wire storage block 11 has entered the space inside the winding block 10. Further, the lower end of the wire storage block 11 is located above the carrier 13 and does not hinder the movement of the carrier 13 in the horizontal direction.

The carrier 13 is formed by combining general pipes, is positioned and mounted on the upper surface of the turntable 14, and is detachable. The turntable 14 is rotatably supported by a support cylinder fixed to a frame, and a lower gear 35 is connected to a motor 36 via a speed reducer. The turntable 14 is driven to rotate by the drive of the motor 36, and the carrier 13 is also rotated accordingly.

A through-hole 40 is formed in the center of the turntable 14, and a rod 41 having a thread formed on the outer surface thereof is vertically arranged so as to penetrate the through-hole 40. It is fitted inside. A gear 42 is attached to a lower end of the rod 41, and the gear 42 is connected to a motor 43, and a top plate 44 is attached to an upper end of the rod 41 so as to be rotatable with respect to the rod 41.

Further, two fixed rods 4 are provided in parallel with the rod 41.
5 is provided, and the fixing rod 45 is supported so as to be able to move up and down through the support cylinder. The lower end of the fixing rod 45 is
The upper end is fixed to the connecting plate 48 through the top plate 44, and is fixed to the receiving plate 47.
5 are connected. Thus, when the cylinder 46 operates, the fixing bar 45 moves up and down. Note that the fixing bar 45 and the top plate 44 are both at positions lower than the upper end of the carrier 13. Further, the rod 4 is driven by the motor 43.
1 is rotated, but the top plate 44 is prevented from rotating by the fixing bar 45 and does not rotate.

The transmission member 15 is composed of a plurality of rods attached diagonally downward to the ribs 26 of the wire storage block 11, and a pair of engagement pieces 51 formed on the upper surface of the carrier 13.
It can be inserted between. Therefore, carrier 1
By the rotation of 3, the rotation is transmitted to the wire storage block 11 via the transmission member 15.

The push-up pins 52 are
Is mounted so as to protrude upward from the carrier 13, and the push-up pin 52 can be brought into contact with the fixed body 32 of the disk 28. That is, as shown in FIG. 3, when the fixing rod 45 is raised, the push-up pin 52 is also raised and abuts on the fixed body 32.
3 is lifted against the biasing force. Then, the support rod 2
1 rotates clockwise, its outer end is lowered, and the transmission member 15 is engaged with the carrier 13. The wire storage block 11 is also lowered to the extent that the upper surface of the carrier 13 is hidden.

Conversely, when the fixing rod 45 is lowered, the push-up pin 52 is also lowered and separated from the fixed body 32. Then
The disc 28 is lowered by the urging force of the spring 33, the outer end of the support rod 21 is raised, the wire storage block 11 is raised, the transmission member 15 is separated from the carrier 13, and the driving force from the carrier 13 is reduced. Cut off. Therefore, the moving means releases the engagement between the transmission member 15 and the carrier 13, and is specifically constituted by the cylinder 46, the fixing rod 45, the push-up pin 52, the fixed body 32, the disk 28, and the support rod 21. Is done.

The loading arm 12 has a horizontal surface on which the wire W is placed, and this horizontal surface protrudes outward from the gap of the carrier 13. A guide bar 56 passes through the base 55 of the loading arm 12, and the guide bar 56 is fixed to the turntable 14. The base 55 of each loading arm 12 is integrally formed in a cylindrical shape,
1 is rotatably fitted to the lifting / lowering body 57 screwed to the outside. The fixing rod 45 penetrates through the elevating body 57 and is prevented from rotating. The rotation of the rod 41 causes the elevating body 57 to move up and down without rotating, and the loading arm 12 moves up and down while rotating together with the carrier 13. The loading arm 12 rises to a position slightly lower than the lowered storage line block 11 and lowers to a position where it completely enters the through hole 40.

Then, based on the stored dose of the loading arm 12, the driving of the motor 43 is controlled so as to intermittently lower by a fixed amount. As a means for detecting the stored dose, an optical sensor and a mirror 58 are used as in the related art. Besides this, the length of the wire W is detected by a measuring roller,
By calculating the weight from the pressure applied to the loading arm 12, the stored dose can be detected.

In the drawing, reference numeral 60 denotes a chuck for gripping the wire W, and reference numeral 61 denotes a vertical wall for restricting the wire W from entering too much on the horizontal plane of the loading arm 12.

Next, the operation during the winding operation will be described. At this time, the wire storage block 11 descends and the carrier 1
The transmission member 15 is engaged with the carrier 13. The rotation of the turntable 14 causes the carrier 13 to rotate, and accordingly, the wire storage block 11 also rotates. The take-up block 10 is also driven to rotate, and the wire W supplied from the outside is taken up by the take-up block 1.
The wire W is wound several times to zero, and the wire W is pushed down by the wire W wound up later, and gets over the ring 17 and winds around the wire storage block 11. Then, the wire W wound around the wire storage block 11 slides down and is loaded on the loading arm 12. When the stored dose of the wire W becomes a predetermined amount,
The motor 43 is driven to rotate the rod 41, and the loading arm 12 is lowered by a certain amount. By intermittently lowering the loading arm 12 as the wire W is stored, the wire bundle T is kept in a clean state in which the wire W is not loose.
Is formed.

Since the winding speed of the winding block 10 and the winding speed of the wire storage block 11 are the same, the rotation speed of the wire storage block 11 having a diameter larger than that of the winding block 10 is reduced. The rotation speed is lower than the rotation speed of the take block 10. The average winding coil diameter of the wire bundle T is the diameter D of the wire storage block 11.
2, the wire bundle T having an average winding coil diameter larger than that of the related art is obtained, and the volume of the wire bundle T is increased.
Therefore, it is possible to wind up a winding form having a high space factor at a high speed.

When it is detected that the loading arm 12 has been lowered to the lower portion of the carrier 13, the rotation of the turntable 14 and the winding block 10 is stopped, the wire W is cut, and the loading arm 12 is inserted through the turntable 14. Hole 40
, The wire bundle T is received by the carrier 13. At this time, when the cylinder 46 is operated to lower the fixing rod 45, the push-up pin 52 is separated from the fixed body 32. Then, the outer end of the support rod 21 is raised by the urging force of the spring 33, and the wire storage block 11 is raised, so that a gap is formed between the storage rod 11 and the carrier 13. The transmission member 15 is also separated from the carrier 13. Then, the carrier 13 is unloaded from the turntable 14 and replaced with an empty carrier 13.

It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that many modifications and changes can be made to the above-described embodiment within the scope of the present invention. For example, the transmission member may be provided not on the wire storage block but on a carrier or a guide rod. Further, although the moving means moves the storage block up and down, the carrier, that is, the turntable may be moved up and down, and may be any mechanism that relatively moves the storage block and the carrier. Or,
The transmission member may be directly moved by a motor, a cylinder, or the like.

[0033]

As is apparent from the above description, according to the present invention, a storage block having a diameter larger than that of the winding block is rotatably provided on the winding block, and a carrier rotatably driven by the storage block is provided. Is transmitted by the transmission member, the wire rod is wound around the wire storage block with a large diameter, the coil diameter of the wire bundle increases, and the volume can be increased. In addition, the wires can be stacked in a dense state even at high speed operation, so that the winding form can have a high space factor.

Further, since the storage wire block is detachably attached to the take-up block, it can be replaced with a storage wire block having a different diameter, and wire bundles having different coil diameters according to the carrier can be easily obtained.
