Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding type electric heater making machine for winding a sheathed heater on the same plane. [0002] A conventional sheath heater winding process will be described. [0003] First, as shown in FIG.
The conical jig 102 is arranged on the upper part of the table, and the conical jig 102 is rotated at a constant speed by a motor 103 via a shaft 104. A conical jig 102 includes a sheath heater 105.
A groove corresponding to the outer diameter of the conical jig 10 is formed.
The sheath heater 105 is wound up in accordance with the rotation of No. 2. [0005] Next, as shown in FIG. 7, the wound sheath-shaped heater 105 is removed from the conical jig 102 and placed on a table 106. Then, the sheet is pressed many times by the strong force of the press machine 107 disposed on the upper side until the sheet becomes flat, and a finished product is obtained. Reference numeral 108 denotes a motor. In the conventional sheath heater winding process, when the sheath heater 105 in the state shown in FIG. 6 is detached from the conical jig 102, the sheath heater 105 may become larger than a predetermined size due to a springback phenomenon. is there. In the press 107 shown in FIG.
No matter how much compression, it returns to the original state due to the spring force of the sheath heater 105, so it is not very coplanar without considerable pressing for a long time, and another straightening machine is required for final finishing. . This is not preferable for plastic working. That is, the external force 6 is repeatedly applied to the sheath heater 105 as a raw material.
Is added, the stress is applied to the tube material or the core wire outside the sheathed heater 105, which affects the material strength and corrosion or electric existence and involves flattening of the product by the compression process, and does not maintain a circular shape as a finished product, It is in a semicircular shape.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in more detail hereinafter with reference to specific embodiments illustrated in the accompanying drawings, in which: FIG. The sheath heater 12 is a heater in which a heating core wire is housed in a sheath of a metal cylindrical tube with a densely filled insulating material interposed therebetween. As shown in FIG. 1 and FIG. 2, a guide plate for guiding the sheath heater 12 when the disk 1 is rotated and the sheath heater 12 is wound by erecting a central shaft 2 at the center of the upper surface of the disc 1. 3 stands on the disk 1. A side pusher 4 for pressing the sheath heater 12 locked to the center shaft 2 from the side is disposed on the side of the sheath heater 12 to be wound. The side pusher 4 moves forward and backward by the air cylinder 5. After the sheath heater 12 has been wound a predetermined number of times, the side pusher 4 is retracted, and then the sheath heater 1
The pusher guide roller 6 that guides the sheath heater 12 by contacting and pressing the sheath heater 12 from the side of No. 2 is disposed on the side of the sheath heater 12 to be wound. A clamp roller 7 for lowering the wound sheath heater 12 from above the disk 1 to prevent the sheath heater 12 from floating is disposed above the disk 1. The clamp roller 7 also moves up and down by the air cylinder 8. Needless to say, the clamp roller 7 presses the sheath heater 12 while avoiding the central shaft 2, the guide plate 3, the side pusher 4, and the pressure guide roller 6. The disk 1 is rotated by a motor 9 in the direction of the arrow. Reference numeral 10 denotes a groove formed in the upper surface of the disk 1 in the radial direction for dropping the end of the sheathed heater 12. Reference numeral 15 denotes a cover plate that covers the groove 10. Sign 1
Reference numeral 1 denotes a roller provided on the outer periphery of the disk 1 for guiding the sheath heater 12. As shown in FIG. 3, an end of the sheathed heater 12 is formed with a ring portion 13 so as to be able to be locked on the central shaft 2 so as not to interfere with a portion which is dropped into the groove 10 and spirally wound. A recess 14 is formed. Next, the winding process of the sheathed heater 12 will be described. First, the ring portion 13 of the sheathed heater 12 is fitted to the center shaft 2 of the disk 1, the recessed portion 14 of the sheathed heater 12 is fitted to the groove 10 of the disk 1, and the cover plate 15 covers the groove 10. Next, the air cylinder 8 is driven to lower the clamp roller 7 so that the clamp roller 7 contacts the sheath heater 12.
The sheath heater 12 is prevented from rising when being wound. At the same time, the side pusher 4 is advanced by the air cylinder 5 and is brought into contact with the sheath heater 12. Next, the disk 1 is rotated by the motor 9 to form the disk 1 along the center axis 2 and the guide plate 3, and the disk 1 is stopped at one rotation. Subsequently, in order to secure the coil pitch of the winding, when the sheathed heater 12 makes one rotation, the string-shaped spacer 16 is interposed and continuous winding is performed. The string-like spacer 16 is made of natural rubber, synthetic rubber, or plastic, and is processed to an appropriate size in consideration of the winding pitch. When the number of windings reaches two, the air cylinder 5 is driven to retract the side pusher 4, and the roller 11 is pressed against the sheath heater 12 from the side to guide the sheath heater 12. The disk 1 is rotated up to a predetermined number of turns while sandwiching the string-like spacer 16. After the predetermined number of turns has been counted, the disk 1 is rotated by one turn in order to take out the wound sheath heater 12. When the rewinding is completed, the disc 1 is stopped, the clamp roller 7 is raised, the product is taken out, and the winding process is completed. The sheathed heater 12 of the product taken out is as shown in FIGS. 4 and 5, and the sheathed heater 12 is taken out after the cover plate 15 is removed. According to the present invention, as described above, the rotating disk, the center shaft raised on the disk for locking the ends of the sheathed heater, and the disk rotated to wind the sheathed heater. end of the sheathed heater from <br/> a guide plate having upright on the disk guiding the sheathed heater, the cover plate covering the grooves and grooves which are engraved on the top surface of the disc radially Translate the ends of the sheathed heater when It was engaging and advancing and retracting a sheath heater engaged to the central axis by an air cylinder pressurized from the side
Wind the side pusher and sheathed heater a predetermined number of times.
After retracting the side pusher , the sheath heater is guided by contacting and pressing the sheath heater from the side of the sheath heater.
The pusher guide roller and the sheathed heater to be wound are lowered from above the disk, and the center shaft, guide plate,
Avoid the pusher and pusher guide rollers
