Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a heat treatment apparatus for a spiral part and a heat treatment method for a spiral part, and more particularly to a technique suitable for a processing and assembling apparatus for a coil spring which is a spiral part requiring a heat treatment step.
[0002]
[Prior art]
According to the spring processing and assembling device, which is a spiral part, after winding a wire such as a piano wire or a stainless steel wire, the external dimensions are inspected (free length), and the residual stress during the winding is reduced. In order to remove it, heat treatment is performed at about 300 ° C. to 500 ° C. for a predetermined time. For this purpose, a large number of wound coil springs are collectively put into a case and put into a heat treatment furnace of a heat treatment apparatus for each case to perform heat treatment.
[0003]
In order to automatically assemble the coil spring completed in this way, it is necessary to align the components with an alignment device such as a parts feeder to separate the individual coil springs, and to grip and move with a robot or the like to assemble the container with the container body. I have to.
[0004]
However, in this method, since the spring is entangled in the parts feeder, the reliability of alignment before the robot or the like is gripped is low, so that the operation rate of the automatic assembly line is reduced. As a countermeasure against these problems, an apparatus having a configuration shown in an external perspective view of FIG. 8 is known as a conventional heat treatment apparatus.
[0005]
In this drawing, the coil spring W manufactured by the spring manufacturing machine 160 is selected by the inspection device 150 and sequentially dropped into the rain gutter-shaped receiving member 171 to be moved downstream along the member 171 to perform heat treatment. Heat treatment was performed by spirally passing through the furnace 170.
[0006]
Further, as shown in the external perspective view of the conventional heat treatment apparatus in FIG. 9, after the coil spring W manufactured by the spring manufacturing machine 160 is selected by the inspection apparatus 150 and sequentially dropped into the rain gutter-shaped receiving member 171, Then, the heat treatment is performed by inserting the spring into the pin P holding the spring on the belt compare moved by the robot device 181 and passing the heat through the heat treatment furnace 180 by the belt compare.
[0007]
On the other hand, as disclosed in Japanese Patent Application Laid-Open No. 5-007961, a hook portion of a coil spring integrally formed with a hook portion is hung from a rod, and the spiral is formed by rotating around the rod and forming a spiral groove. There has also been proposed a "post-processing device for a coil molded product" in which a hook portion is positioned on a shape member and a coil spring is sent to a heat treatment unit for each coil spring.
[0008]
[Problems to be solved by the invention]
However, there is a case where heat treatment cannot be performed uniformly in a batch process in a case. In addition, in the case of the apparatus configuration described with reference to FIG. 8, there is a case where the coil springs overlap or become entangled at the time of collision because there is no function of regulating the posture of the coil springs W and the contact between adjacent components in the heat treatment furnace. When such a situation occurs, there is a disadvantage that the heat treatment time varies and the heat treatment becomes non-uniform.
[0009]
Further, when the coil spring W becomes entangled in the heat treatment furnace, in order to eliminate the entanglement of the coil spring W, a part of the furnace 170 must be opened, the furnace temperature must be lowered, and the furnace temperature must be raised again after the treatment. The time required for the operation, which has led to a decrease in the line operation rate.
[0010]
On the other hand, in the case of FIG. 9, the heat treatment furnace 160 becomes considerably large because a compare is used, and a transfer device 181 for picking and placing each of the holding pins P on the compare from the winding machine is required. Therefore, there is a problem that the cost is increased. In addition, the use of a pick-and-place transfer apparatus may cause a trouble at the time of transfer, resulting in a decrease in the line operation rate. For this reason, there is a problem that the apparatus cannot be directly connected to the automatic assembly line.
[0011]
The proposal disclosed in Japanese Patent Application Laid-Open No. 5-007961 can successively transport each piece as much as possible. However, there is a problem that the method is limited to a method in which a hook portion is integrally formed with a coil spring.
[0012]
Therefore, the present invention has been made in view of the above problems, and can easily configure the entire heat treatment apparatus for a spiral part, without causing the spiral part to be entangled, and in an automatic assembly line.

Is for moving the vibrator by transmitting vibration in the feed direction of the coil spring W (from right to left on the page). Reference numeral 13 denotes a separating frame, which is configured to separate one leading coil spring W from the other, and to transfer the separated coil spring W to a subsequent process by a transfer robot (not shown).
[0036]
In the apparatus configured as described above, the operation will be described with reference to the operation description flowchart of FIG. 5. In step S1, the coil spring W wound by the coiling machine 60 that winds the coil spring W proceeds to step S2. The free length of the coil spring W is measured by the non-contact type sensor 51 in a state where the processing is completed and held (Step S3), and the non-defective product is passed to the next process, and the defective product is discharged by the discharger (Step S4).
[0037]
If it is determined that the coil spring W is non-defective, the coil spring W that has been wound and inspected is dropped on the gutter-shaped rail 24 in step S5. The gutter-shaped rail 24 has an inclined portion 24a, and the coil spring W slides down. In step S6, the cylinder 41-2 for operating the flow stop gate of the charging / separating device 40 for charging the coil springs W one by one into the heat treatment furnace is turned on, and in step S, the gate pin 41-1 is turned on to stop the damping. . That is, the pusher cylinder 42-1 presses the coil spring W just before the damped coil spring W by the pressing portion 42-2.

When the first-stage circumferential feed mechanism (the same applies to the second-fifth-stage circumferential feed mechanism) rotates by 30 °, the blade member 23-a-2 pushes the rear end of the coil spring W with the pressing portion 30 by about 15 degrees. Rotate by a minute. When the supply rotation operation of the coil spring W is further repeated three times, the coil spring W of the first day is placed on the gutter-shaped rail 21-b of the second-stage circumferential feed mechanism from the drop hole of 21-ah, and the coil spring W is moved. Falls.
[0043]

[0044]
Further rotation by 30 ° results in 360 ° (one rotation).
[0045]
When the third-stage circumferential feed mechanism repeats this operation five more times, the coil spring W falls from the falling hole 21-ch onto the gutter-shaped rail 21-d of the fourth-stage circumferential feed mechanism.
[0046]
Further rotation by 30 ° results in 360 ° (one rotation).
[0047]
Fourth-stage circumferential feed mechanism When this operation is repeated five times, the coil spring W falls from the falling hole 21-dh onto the gutter-shaped rail 21-e of the fifth-stage circumferential feed mechanism.
Further rotation by 30 ° results in 360 ° (one rotation).
[0048]
When the fifth-stage circumferential feed mechanism repeats this operation four more times, the coil spring W falls from the falling hole 21-eh onto the sixth-stage gutter-shaped rail 21-f outside the heat treatment furnace. In this process, the heat treatment is completed.
[0049]
The coil spring W that has fallen onto the sixth gutter-shaped rail 21-f is moved to the gutter-shaped rail 24 by the pusher 14, and the operation is further repeated to align and retain the coil spring W that has been subjected to the winding process and the heat treatment process. The coil spring W is moved onto the device 10 for separating.

[0054]
The pulley 52 is connected to the shaft 53 and is also interlocked with the pulley through the belt 51. The pulley and the motor 29 are connected.
[0055]
In the above configuration, the coil spring W wound by the coiling machine 60 that winds the coil spring W is measured with a 51 non-contact type sensor in a state where the winding process is completed and the non-defective product is processed in the next step. Defective products are discharged by a discharger (not shown). Numeral 24 denotes a gutter-shaped rail for dropping a coil spring W wound thereon.

[0058]
When it is confirmed that there is no coil spring W by the presence / absence sensor 21 of the entrance of the heat treatment furnace 20, the gate 41-1 is opened and the coil spring W slides down. Is detected, and in that case, the coil spring W moves by rotating the screw-shaped spiral feed member 54 that moves the coil spring W.
[0059]
