Description

  The present invention relates to a golf club disassembling apparatus for use in separating a golf club head and a shaft.

  In golf clubs purchased by consumers, the shaft is often pulled out of the head and replaced with a new shaft or head. For example, you may want to replace the shaft with one with a different rigidity or with a different material, or conversely, you may want to use the shaft as it is and replace the head with a member with a different weight or material. .

  The golf club head / shaft joint is bonded and bonded with an adhesive such as an epoxy resin. To separate the shaft and head, the joint can be separated from 150 ° C. using an isoheating tool such as a gas torch. It has been performed by a method in which the adhesive is melted by heating to about 200 ° C., the adhesive force is lowered, the shaft is fixed, and the head is pulled out.

Conventionally, in such separation of the head and shaft, as an apparatus for pulling the shaft from the head, for example, a puller as shown in FIG. 19 is used.
This extractor has a fixed base 72 fixed to one end of a base 71, and a pulling plate 74 that moves in the front-rear direction by being guided by a guide groove 73 formed in the base 71 in front of the fixed base 72. An extraction bolt 79 is screwed on the fixed base 72 and its tip is engaged with the extraction plate 74. Further, a semicircular groove 75a for clamping the shaft is formed on the upper surface of the fixed base 72, and a clamping plate 76 having a semicircular groove 75b for clamping the shaft is provided on the lower surface, and a bolt is inserted into the clamping plate 76. A female screw is formed in the fixing base 72 and a fixing bolt 77 is screwed to these holes, and a shaft fitting groove 78 is formed on the upper surface of the pulling plate 74.
For the pulling operation of the puller, the golf club from which the socket has been cut and removed is first placed as shown by the dotted line in FIG. Next, the clamping plate 76 is fastened to the fixing base 72 by the fixing bolt 77 through the bolt insertion hole, and the shaft is clamped by both the semicircular grooves 75a and 75b. Next, the extraction bolt 79 is manually rotated to advance the extraction plate 74 in the head side direction. As a result, the front surface of the extraction plate 74 is locked to the end of the hosel portion of the head, and the head is extracted from the shaft. At the time of this drawing, the hosel part of the head is heated to melt the adhesive that holds the shaft.

The golf club head remover disclosed in Patent Document 1 can remove the head from the shaft as shown in FIG. 20, and the male screw 81 is turned at this time. As a result, the lower sandwiching body 82 is moved to the left, thereby bringing the coil spring 83 into a state of stocking force. In this state of stocking, the tip portion of the shaft of the golf club is fitted into the notch 84 and the hosel is At the same time, the upper clamping body 85 is lowered from the screw 86 and the shaft is clamped between the upper clamping body 85 and the lower clamping body 82. In this clamped state, the male screw 81 is turned back in the opposite direction to create a gap between the support portion 87 and the slip-off preventing portion 88, and the working force of the coil spring 83 is applied to the shaft to the shaft and the hosel (head). In this applied state (tensioned state), the shaft is inserted into the hosel from where it is inserted with a heating tool such as a dryer, and around the location in the shaft hosel. A golf club head remover is disclosed in which the adhesive that has been poured and hardened is melted, and when the adhesive force is weakened by this melting and the tension force wins, the tension force removes the head from the shaft. Yes.
JP-A-9-75488

However, in the above-described conventional extractor shown in FIG. 19, the hosel part is heated with a heating tool such as a dryer or a gas torch to melt the adhesive that holds the shaft bonded. Then, it is difficult to control the hosel part to have a predetermined temperature.
Therefore, when heated at a temperature equal to or higher than the melting point temperature of the adhesive, the high temperature may affect the material of the shaft and head, which may cause a problem that the shaft and head cannot be reused. .
In particular, in an FRP shaft, the performance of the material is likely to change due to the influence of heat from heating, and it is important to control the heating temperature at a temperature near the melting point of the adhesive.
Further, if the extraction plate 74 is moved forward at a temperature lower than the melting point temperature of the adhesive, the shaft may be forcibly pulled and damage the shaft.

  In addition, the golf club head remover disclosed in Patent Document 1 is configured such that the shaft insertion portion of the hosel is heated from the outside with a heating tool such as a dryer or a gas burner, and the portion around the portion existing in the hosel of the shaft is When the adhesive that has been poured and solidified is melted and the adhesive force is weakened by this melting and the tension force of the spring wins, the tension of the spring causes the head to come off from the shaft. With tools, it is difficult to control the temperature of heating, and in most cases, heating is performed at a temperature higher than the melting point temperature of the adhesive. Therefore, as in the conventional example, the heating may change the structure of the material of the shaft and the head due to high heat, which may affect the material, and may cause a problem that the shaft and the head cannot be reused. is there.

  In the conventional example described above, in order not to affect the material of the shaft or the head by heating with the heating tool, the heated portion should be concentrated as much as possible in the joint portion, or the adhesive should be melted. However, it is difficult and skillful to raise the temperature near the temperature that does not adversely affect the material. In addition, when using a heating tool such as a gas torch, the head or shaft surface is burned because it is heated at a high temperature using a fire, which causes a problem of polluting the environment, such as the generation of a large amount of harmful gases. Occurrence and countermeasures are costly. In addition, since fire is used, there is a danger in handling, and there are buildings that are prohibited from using fire depending on the building.

  Therefore, the present invention solves the above-mentioned problem, and controls the heating temperature when separating the joined head and shaft, so that the shaft and the head can be quickly separated without impairing the reusability of the separated shaft and head.

The induction heating device 50 includes an induction coil 51 and a control unit 60 that controls the amount of power to the induction coil 51.
3 and 4 are perspective views of an induction coil included in the induction heating device and a specific example thereof, FIG. 5 is a block diagram showing an electric circuit of the induction heating device, and FIG. 6 is an operation unit of the induction heating device. The principal part top view which shows a structure, FIG. 7 is a block diagram which shows the electric circuit of another example.

  First, the induction coil 51 provided in the induction heating device 50 of the present embodiment has an induction coil 51 that generates an alternating magnetic field line M for performing induction heating, as shown in FIGS. The induction coil 51 has a core 53 made of a ferromagnetic material having a gap 52 in which a joint between the head and the shaft can be inserted and removed, and a coil 54 wound around the outer periphery thereof.

  The core 53 is made of a material having high magnetic permeability such as ferrite, iron, or a compound that is a ferromagnetic material. As the shape of the induction coil, as shown in FIGS. 3 and 4, C-shaped and E-shaped coils are preferably used. In the gap in the case of the C-shaped, an alternating magnetic field of N_S ← → S_N is present. N_N ← → S_S or N_S ← → S_N alternating magnetic field is generated in the gap in the case of the E-shaped coil.

  Although not shown, this induction coil is usually used by being housed in a case made of a non-conductive material such as a resin and a non-magnetic material.

  As shown in FIG. 5, the induction heating device 50 includes an induction coil 51, a power supply unit 63, a high frequency generator 64, a heating time setting device 65, a heat retention time setting device 66, a volume 67, a counter 68, and an operation switch 69. It is the structure which has the control part 60 provided with. The induction coil 51 and the control unit 60 are connected via a power supply litz wire 55.

The control unit 60 having the following configuration is configured to comprehensively control the induced power.
The power supply unit 63 is connected to an external power supply 61 via an AC cord 62, and rectifies the supplied power and supplies the rectified power to the following other circuits.

  The high-frequency generator 64 is connected to the induction coil 51 via a power supply litz wire 55, and generates a high-frequency current of about 10 kHz to 100 kHz, for example, and supplies it to the induction coil 51.

  As the high-frequency generator, for example, a device that generates a current or a voltage that is controlled by using an IPM (intelligent power module) computer and controls a pulse width of a predetermined frequency is used.

  The heating time setting device 65 sets the energization time to the induction coil required for one heating operation, and is set after receiving a signal of the energization operation from the operation switch 69 via the power supply litz wire 55. A control signal is output to the high frequency generator 64 during the energization time.

  The heat retention time setter 66 sets an energization time for outputting electric power lower than that of the heating operation to the induction coil, and is set after receiving an energization operation signal from the operation switch 69 via the power supply litz wire 55. A control signal is output to the high frequency generator 64 during the energization time.

  The volume 67 controls the pulse width, and the counter 68 counts the number of energizations.

  From the above, the high-frequency generator 64 supplies the current to the induction coil 51 while receiving these control signals, that is, for the set energization time.

  The operation switch 69 is provided in the control unit 60 so that an operator can input an operation start operation. The energization time setting or the heat retention time setting in the heating time setting unit 65 is performed. The setting of the energizing time in the device 66 can be arbitrarily adjusted.

For example, as shown in FIG. 6, the operation switch 69 includes a heating operation button 65b, a heat retention operation button 66b, an automatic operation button 57, a heating timer 65a, a heat retention timer 66a, an operation LED 58, and a heating state LED 59.

The heating timer 65a and the heat retaining timer 66a set the heating time and the heat retaining time in automatic operation, and the timer has two digits (unit is second).
The automatic operation button 57 discloses or stops automatic operation at a time set in the heating time timer and the heat retention time timer when the user presses the button.
For example, when the heating time is set to 15 seconds and the heat retention time is set to 30 seconds, when the user presses the automatic operation switch, the user heats for 15 seconds and then automatically about 40% of the heating time. The power is kept for 30 seconds, and the output is stopped when the heat insulation is finished.
The operation LED 58 displays that the induction heating device 50 is powered on.
The heating state LED 59 displays the heating state. For example, the display section of the heating operation and the heat retention operation is implemented by a three-color LED. When the LED is red, the heating is being performed. When the LED is yellow, the heat is being maintained. When the LED is green, an indication that the set heating time or heat retention time has ended is executed.

The operation of the induction heating device 50 having the above configuration will be described.
The operator moves the induction coil 51 and arranges the induction coil 51 so as to be close to the head 2 as shown in FIGS. 3 and 4. In this state, the operator starts heating with the operation switch 69. Induction heating for the head 2 is started.
Then, a current is supplied to the induction coil 51 for the energization time set in the heating time setting device 65, and magnetic field lines M are generated around the induction coil 51 around the core 53 as shown in the figure.
The core 53 functions as a magnetic path that controls the spatial distribution of the magnetic force lines M, that is, a magnetic flux path that allows the magnetic force lines M to converge and pass through the core 53, and the magnetic force lines M are orthogonal to the head 2 from the facing surface of the facing portion 53 a of the core. And let it pass.
When the alternating magnetic field lines M pass through the head 2, an eddy current I is generated around the head 2 including the head 2 by an electromagnetic induction effect. When this eddy current I flows, Joule heat is generated, whereby induction heating of the head is performed.

  Therefore, by flowing a high-frequency current through the induction coil 51, the head 2 is induced by the magnetic field generated from the induction coil 51, and the induced current flows through the head 2. Then, the induced current passes through the joint 4a of the head 2, so that the temperature of the joint 4a is increased in a short time, and the heat heats the adhesive between the head and the shaft. Is melted to reduce the adhesive force between the two.

In this way, when disassembling the golf club, the head is heated by induction heating, the adhesive contacting the head and the shaft is melted, and the adhesive force between them is reduced to reduce the resource reuse point of view. It is possible to easily achieve complete separation of the head from the shaft and the shaft.
Furthermore, because the head is heated by controlling the heat generation temperature due to induction heating of the head to a predetermined temperature, it is possible to expand the application when reusing the head and shaft, and to suppress the generation of smoke and bad odor as much as possible. Can do. Thus, a golf club disassembling apparatus that can disassemble the golf club economically, efficiently, and without pollution can be provided.

  Further, as shown in FIG. 7, a signal from a thermocouple for detecting the temperature of the head 2 heated by the induction coil 51 is input to the temperature control unit 60a, and the signal from the temperature control unit 60a is converted into a signal. It is also possible to adjust the heating temperature of the head 2 by controlling the control unit 60 based on the above.

  Next, the separation device according to the present embodiment using the induction heating device 50 configured as described above will be described.

  In the separating apparatus, when the adhesive is melted by the head heated by the induction coil and the adhesive force is reduced, the head and the shaft are separated from each other by the acting force of the separating means, so that it is surely quick. It is set as the structure which can be isolate | separated into.

FIG. 15 is an explanatory view showing a state in which the induction coil is arranged in the decomposer shown in FIGS. 13 and 14, and FIGS. 16 and 17 are explanatory views showing other examples of the driving device. .
In addition, about the same structural member in each following Example, the same code | symbol is attached | subjected and demonstrated.

  The separating device 20 includes a mechanism for fixing a part of the shaft 3 of the golf club, a pressing member 23 for supporting the joint portion of the head, and a driving device 21 for moving the pressing member 23 to separate the head and the shaft. It was set as the structure provided with the press mechanism.

As shown in FIGS. 8 and 9, the mechanism for fixing the shaft has a lower holding member 34 fixed to one end of a base 26, and the upper holding surface 34 c of the lower holding member 34 has a shaft holding member. An upper holding member 33 having a groove 33a for holding the shaft on the lower surface is attached to the lower holding member 34 via a hinge 39.
The upper clamping member 33 is formed with a bolt insertion groove 38a, the lower clamping member 34 is formed with a female screw 38b, and the fixing bolt 38 is screwed to the upper clamping member 33 so that the upper clamping member 33 is positioned on the lower side. The shaft 3 is fixed by acting so as to be pressed against the pinching member 34 and sandwiched from above and below. In addition, elastic bodies 33b and 34b are provided at locations where the upper and lower clamping members 33 and 34 are to be clamped so as not to damage the shaft.

  Next, the pressing mechanism is provided with a pressing member 23 that moves in the front-rear direction as guided by a guide groove 24 formed in the base 26 in front of the lower holding member 34 as the driving device 21. The clamping member 34 is screwed with a separation bolt 36 and its tip is engaged with the pressing member 23. Then, the separation bolt 36 is fixed to the pressing member 23, and a handle 37 attached to one end of the separation bolt 36 is turned in one direction to give a rotational motion to the separation bolt 36. With the rotation of the bolt 36, the pressing member 23 is advanced in one direction on the axis of the separating bolt, and the pressing member 23 is moved in a direction to separate the head 2 and the shaft 3.

  Further, the pressing member 23 is formed with a shaft fitting groove 23a opened on the upper surface, and the groove width of the shaft fitting groove 23a is larger than the diameter of the shaft and larger than the end face diameter of the hosel portion 4 of the head. It is set small. Therefore, by the movement of the pressing member 23, the front surface of the pressing member 23 is engaged with the end surface of the joint 4 a of the head 2, and the head 2 is pulled out from the shaft 3 and separated.

In this embodiment, a hosel abutting member 25 having a shaft fitting groove that allows the shaft to pass therethrough is inserted between the hosel portion 4 and the pressing member 23, and the hosel is moved by the movement of the pressing member 23. The abutting member 25 also advances, whereby the front surface of the hosel abutting member 25 is locked to the end surface of the joint portion 4a in the head 2, and the head 2 is pulled out from the shaft 3 and separated.
In this separation, the joint portion of the head is heated by the induction heating device to reduce the adhesive force of the adhesive that holds the shaft.

  As described above, according to the separation device 20 shown in FIGS. 8 and 9, the joint 4 a of the head 2 is effectively heated by the induction heating device, so that the joint of the heated head 2 is heated. 4a melts the adhesive in contact with the head and the shaft, lowers the adhesive force, and in the lowered state, the end of the joint 4a is pressed by the pressing member 23. The head 2 and the shaft 3 are quickly separated.

  The step of separating the head and the shaft by the separating device 20 may be performed after induction heating as in the embodiment, but may be performed during heating if the adhesive is in a lowered state.

However, the present invention is not limited to this, and the cooling fan is located at a position where the induction coil 42 can be cooled after heating. What is necessary is just to be arrange | positioned.

Further, in some golf clubs, a weight (not shown) may be inserted into the tip of the shaft in order to obtain a set value with respect to a balance value set in advance in the golf club.
Therefore, when the weight is separated from the shaft after the head 2 and the shaft 3 are separated, if the induction coil 51 is disposed in the vicinity of the joint portion 4a of the head 2, the workability deteriorates. The induction coil 51 may be moved away from the vicinity of the head 2.

For example, as shown in FIG. 11, a support base 47 is fixed on the base 26, and a moving shaft 48 is inserted into the support base 47. An induction coil 51 is attached to the moving shaft 48, and the moving shaft 48 can be configured to slide in the vertical direction of the golf club.

The clamping member 33 acts so as to press against the lower clamping member 34 and is clamped and fixed from above and below.

  Further, grooves 33a and 34a for sandwiching the shaft are formed in the front-rear direction at the center of the upper and lower clamping members 33 and 34. It should be noted that elastic materials 33b and 34b are provided at locations where the upper and lower clamping members 33 and 34 are to be clamped so as not to damage the shaft.

Moreover, as the drive device 21 of the separating apparatus 20 shown in FIGS. 13 and 14, when the adhesive force of the heated adhesive is reduced, an acting force is automatically applied in the direction in which the shaft and the head are separated. The structure is not limited to this as long as the structure can be used.
For example, as shown in FIG. 16, a drive motor 27 is used as the drive device 21, and the rotary shaft 28 is rotated by the driving force of the feed motor 27 so that the pressing member 23 moves forward. Examples of the driving device 21 include a configuration in which the air 27a or hydraulic pressure is used to rotate the rotating shaft 28 by the air 27a or hydraulic driving force and the pressing member 23 is advanced.
