Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a grip insertion device for a golf club.

[Conventional technology]

It has been desired to automate the process of inserting grips and shafts for golf clubs of this type.

In other words, an elastic grip made of rubber or the like is placed opposite a shaft made of metal or the like, the grip or shaft is inserted and moved, the rear end of the shaft is inserted into the edge of the grip opening, and the insertion is completed by inserting and moving the grip as it is. This is what I am trying to do.

Adhesive tape is attached to this shaft to increase the degree of adhesion between the grip and the shaft.

[The problem that the idea aims to solve]

However, in the case of this proposed structure, when the grip is inserted, the inner surface of the grip and the rear end of the shaft come into contact with each other, and the shaft is inserted while the grip is being pushed open.Therefore, there is a risk that the shaft will be inserted forcefully, and the inner surface of the grip may be damaged. It has the following disadvantages.

[Means to solve the problem]

The purpose of the present invention is to solve these inconveniences. and a nozzle mechanism for blowing compressed air into the golf club.

[Effect]

The opening end of the grip is held expanded by the expansion mechanism, and the grip and shaft are inserted into the grip while compressed air is blown into the grip by the nozzle mechanism.

Reference numeral 15 denotes an expansion mechanism, which fixes a mounting member 16 to the upper part of each support column 4, and a mounting plate 1 between the mounting members 16.
7, a small support 18 is installed vertically between the upper plate 5 and the mounting member 17, a cylinder mounting plate 19 is fixedly installed between the small supports 18, and expansion cylinders 20 are installed radially on the mounting plate 17. Attach the three rods 20a of the expansion cylinder 20 to a pair of directly connected pieces 21a, 2
1b are connected to one connecting piece 21a that is bendably connected to each other with a pin 22, and an expanding piece 23 is connected to the other connecting piece 21b, and the expanding piece 23 has an expanding piece that can come into contact with the inner surface of the grip 1. The escape cylinders 24 are radially attached to the cylinder mounting plate 19, and the rods 24a of the escape cylinders 24 are formed with claws 23a.
The connecting piece 25 is pivotally connected to the mounting part 23b of the expansion piece 23 by a pin 26, a clamping cylinder 27 is provided in the mounting part 23b, and the outer peripheral surface of the grip 1 is attached to the rod of the clamping cylinder 27. A pressing piece 28 is provided to press the pressing piece 28 and the expansion claw 23a.
The opening end of the grip 1 is held between the grips 1 and 2 to prevent the grip 1 from slipping out when the grip is expanded.

29 is a nozzle mechanism in which a mounting shaft 30 is installed vertically on the upper plate 5, a nozzle body 31 is fixed to the mounting shaft 30, and a hole is provided at the lower end of the nozzle body 31 that communicates with the insertion hole 1a of the grip 1. A nozzle part 32 that can be fitted into the nozzle body 31 is formed in the nozzle body 31.
A nozzle hole 33 is formed to open at the nozzle hole 33.
A supply pipe 34 connected to a compressed air source (not shown) is connected to the supply pipe 34, and a pneumatic control circuit (not shown) is constructed in the middle of the supply pipe 34.

This pneumatic control circuit blows compressed air into the grip 1 from the nozzle hole 33 along with a solvent such as gasoline just before the grip starts to be inserted, only compressed air is blown after the grip starts to be inserted, and the air inside the grip 1 is blown after the insertion is completed. It is designed to be inhaled instantly.

The air control circuit C is connected to the air pressure source 3 as shown in FIG.
5. Consists of a solvent tank 36, a solvent switching valve 37, a compressed air switching valve 38, a suction switching valve 39, a negative pressure actuator 40, and a pressure regulating valve unit 41. First, the solvent switching valve 37 opens just before starting insertion. , a solvent such as gasoline is blown out from the nozzle hole 33, and in this case it opens and closes for about 1 second, and the pressurized air switching valve 38 opens and compressed air is continuously blown into the grip 1. After the insertion is completed, the compressed air is The switching valve 38 is closed, the switching valve 39 for suction is opened, and the negative pressure actuator 40 performs a suction action.

Since this embodiment has the above-mentioned configuration, the grip 1 is mounted between the nozzle body 31 and the expansion claw 23a as shown in FIG. The clamping cylinder 27 is operated to release the grip 1 using the pressing piece 28 and the expanding claw 23a.
Holding the open end, the expansion cylinder 20 operates,
As shown in FIGS. 4 and 5, the opening end of the grip 1 is expanded from the imaginary line to the solid line position by outward movement of the expansion claw 23a, and then compressed air containing the solvent flows through the nozzle hole 33 of the nozzle body 31 into the grip 1. The shaft 2 is raised by the operation of the vertical cylinder 8, and the upper end of the shaft 2 is inserted from the open end of the grip 1.The shaft 2 is further inserted as shown in FIG. The compressed air in the grip 1 is sucked in through the nozzle body 31 of the nozzle mechanism 29, the escape cylinder 24 and the expansion cylinder 24 of the expansion mechanism 15 operate, and the expansion claw 23a is moved as shown by the solid line in FIG. The shaft 2 with the grip inserted therein is taken out, and the vertical cylinder 8 is lowered to its original position as shown in FIG. 1.

In this insertion process, the opening edge of the grip 1 is expanded and held by the expansion mechanism 15, so that the shaft can be inserted smoothly at the start of shaft insertion, and compressed air is blown into the grip 1 by the nozzle mechanism 29 at the time of insertion. As shown in Fig. 6, the grip 1 expands due to the compressed air, and the compressed air escapes to the outside through the gap R between the inner surface of the insertion hole 1a and the outer circumferential surface of the grip 1. This allows the shaft 2 to be inserted smoothly, and the grip 1 Damage can be suppressed and work efficiency can be improved.

In this case, compressed air containing a solvent is blown into the grip 1 from the nozzle mechanism 29 just before the insertion starts, so the viscosity of the adhesive of the double-sided adhesive tape a decreases, making the insertion of the grip 1 smoother. After the insertion is completed, the compressed air in grip 1 is sucked in, so the residual pressure in grip 1
This prevents it from coming off.

[Effect of idea]

As mentioned above, the present invention uses the expansion mechanism to expand and hold the opening edge of the grip, so that the shaft can be inserted smoothly at the start of shaft insertion, and the nozzle mechanism sucks compressed air into the grip during insertion, so that the grip The shaft expands due to the compressed air, and the compressed air escapes to the outside through the gap between the inner surface of the insertion hole and the outer circumferential surface of the grip, allowing smooth insertion of the shaft, suppressing damage to the grip, and improving work efficiency. .

As described above, the intended purpose can be fully achieved.
