[Action]

[0005] The seal storage tube has a built-in elastic seal member and is supported on the base side. First, the operation of holding the elastic seal member on the seal holding shuttle will be described. The second driving device is driven to make the center axis of the seal holding shuttle coincide with the center axis of the seal storage cylinder, and the first driving device is driven to drive the seal holding shuttle upward.
As a result, the contact plate is inserted into the seal storage tube, and the distal end surface of the support member is aligned with the upper surface of the locking portion. Next, the gap between the contact plate and the support member is set so that the elastic seal member can be received.

In this state, each push rod is pushed into each through hole.
Thereby, a plurality of circumferential portions of one elastic seal member directly locked to the locking portion are pushed into the inner diameter side by the respective push rods, and the inwardly curved protruding portion pushed by the push rods and the push are pushed. Alternating outwardly curved projections between the bars are provided to provide an elastically folded state of reduced profile.

When the elastic seal member is in the elastically bent state, the elastic seal member is sandwiched between the contact plate and the support member. When the elastic seal member is held, each push rod is pulled out and returned. When each push rod returns,
The first driving device is driven to move the seal holding shuttle downward to avoid interference with the seal storage cylinder.

Next, the elastic seal member held by the seal holding shuttle is mounted in the seal groove of the caliper. First, the second driving device is driven to make the center axis of the seal holding shuttle coincide with the center axis of the caliper cylinder. The caliper is previously held in the caliper holding device with the opening of the cylinder facing downward.

When the central axes of the seal holding shuttle and the cylinder coincide with each other, the first driving device is driven to drive the seal holding shuttle upward. As a result, the contact plate is inserted into the cylinder, the distal end surface of the support member is aligned with the lower edge of the seal groove, and the elastic seal member is positioned to face the seal groove. The attachment of the elastic seal member to the seal groove of the caliper is performed by releasing the elastic seal member from being held between the contact plate and the support member. The elastic seal member released from being sandwiched is restored from its elastically bent state to an annular shape by its own elastic restoring force, and is diametrically expanded toward the seal groove in the circumferential direction and is annularly attached. When attaching such an elastic seal member to the seal groove,
Actuate the spreader to ensure its installation.
Let That is, the elastic seal between the contact plate and the support member
Release the clamping of the
Move the spreading member toward the contact plate, and
Insert the sharpened part and the inclined part into the inner surface,
The material is pushed out and restored securely, and the seal groove is sufficient
Push in.

After that, the first driving device is driven to lower the seal holding shuttle to move the seal holding shuttle to a position where it does not interfere with the caliper. Next, the second driving device is driven to move the seal holding shuttle to the seal storage cylinder side. The above operation is repeated while a new elastic seal member is sandwiched between the contact plate and the support member, and a new caliper is held by the caliper holding device.

In this manner, the elastic seal member 105 in the cylindrical portion 10c is lowered integrally until it is locked to the locking portion 11, and fills the lower end portion of the used cylindrical portion 10c. Since the cylindrical portion 10c has a size capable of locking the annular elastic seal member 105 by frictional force,
The elastic seal member 105 does not fall under its own weight.
Thus, the replenishment of the elastic seal members 105 used sequentially from the lower end portion of the cylindrical portion 10c is performed with the posture stabilized.

When the elastic seal member 105 is supplied,
The cylinder device 70 is operated to return. As a result, the seal pushing member 73 is raised, and the seal pushing member 73 is engaged with the positioning device 79 and each ball 79d is engaged with the lower circumferential groove 79b. Return to. By repeating the above operation, each time the elastic seal member 105 is used, one elastic seal member 105 is supplied into the seal storage tube 10. Thus, the stroke of the seal pushing member 73 at the time of replenishment depends on the gap T, the lower circumferential groove 79b and the upper circumferential groove 79.
c.

When a new elastic seal member 105 is not to be refilled in the seal storage cylinder 10, the cylinder device 70 is sufficiently moved forward to operate, and the used cylindrical part 10 which has become a space is used.
The entire elastic seal member 105 in the seal storage tube 10 is lowered so as to fill the lower end portion of c. At this time, the lowering of the seal pushing member 73 and the connecting tool 78 is performed by the positioning device 79 passing through the upper circumferential groove 79c. Thus, up to the last one elastic seal member 105, the seal storage cylinder 10
Can be pushed into the lower end.

【The invention's effect】

As will be understood from the above description, the following effects are obtained by the apparatus for supplying a sealer to a seal groove according to the present invention. Supply of the elastic seal member from the seal storage cylinder to the seal holding shuttle, holding by the seal holding shuttle when the elastic seal member is elastically bent, movement of the seal holding shuttle to the caliper side when the elastic seal member is held, and caliper The series of operations of mounting the elastic seal member in the seal groove is automatically performed.
In particular, the mounting of the elastic seal member in the seal groove of the caliper having the adjuster bolt is reliably and efficiently performed.
Also, the operation of the push-out member causes the sealing of the elastic seal member.
Mounting in the groove.
