Description

DETAILED DESCRIPTION OF THE INVENTION As shown in FIG. 1, the present invention involves inserting sealing discs (packets) B one by one into a bottle lid A formed in the shape of a cap from synthetic resin or a thin metal plate. It is related to equipment.

Conventionally, this type of loading device has been designed to sandwich and lock the disks, which are fed out one by one to the sides from a disk cartridge loaded with a large number of stacked sealing disks, between a pair of left and right leaf springs from both the left and right sides. When a lid is supplied to the lower part of the disc which is clamped and locked by the leaf spring, a ram provided at the upper part of the disc is lowered to push and insert the disc into the lid of the four bottles.

On the other hand, II M A fitted into the bottle opening has a diameter dimension (D
) are different, and therefore the diameter (d) of the disc B inserted into the bottle lid also varies in size.
The device for loading the disk into the bottle cap needs to be able to easily cope with changes in the diameter (d) of the disk B.

On the other hand, in the conventional loading device, the disk fed out from the disk cartridge is held at the top of the bottle lid by a pair of left and right leaf springs, so that the disk is not inserted easily. If the diameter of the disk becomes large depending on the type of bottle cap, the force of pinching from both left and right sides by both leaf springs will increase, so the disk sandwiched between them will Since the attachment bends and deforms due to the force, it cannot be inserted into the bottle lid in the correct state. Also, if the diameter of the disk becomes small, the disk cannot be held between the two leaf springs. This will lead to a situation. Therefore, in the conventional arrangement, when the diameter of the disk changes, the leaf spring must be replaced accordingly, and the operation due to the change in the diameter of the disk is extremely troublesome.

An object of the present invention is to enable a disc loading device of this type to be able to cope with changes in the diameter of the disc extremely easily. A disk cartridge loaded with a large number of stacked sealing disks is arranged vertically, and a disk feeding plate is placed at the bottom of the disk cartridge so as to close the lower end opening of the disk cartridge. The disk feed plate is arranged to be movable in a direction perpendicular to the axis, and a recess is provided on the upper surface of the disk feeding plate into which only one disk in the disk cartridge is fitted, while a recess on the side of the disk cartridge is provided. At these positions, a supply section for the bottle lid is provided below the disk feeding plate, and a suction mechanism is provided above the disk feeding plate to suck the disk and move it downward toward the inside of the bottle cap. and the disk feeding plate is attached to a movable adjustment table configured to move back and forth in the direction from the disk cartridge to the bottle cap supply section and the suction mechanism, and the disk feeding plate is attached to the movable adjustment table, It is characterized by being provided with a reciprocating mechanism that reciprocates between the disk cartridge, the bottle lid, and the suction mechanism.

That is, in the present invention, when the disk feeding plate moves forward from the disk cartridge in the direction of the bottle cap supply section and the suction mechanism by its reciprocating mechanism, only one disk in the disk cartridge is removed from the upper surface of the disk feeding plate. When the disc cartridge is fed out with the disk inserted in the recess, the suction mechanism descends and suction-locks the disk on the upper surface of the disk cartridge plate.Then, when the disk feeding plate retreats to the original position below the disk cartridge, the above-mentioned The suction mechanism lowers and the disk adsorbed thereon is repeatedly pushed and inserted into the bottle lid that has been supplied in advance to the bottle lid supply section at the bottom, thereby loading the disk into the bottle lid. If the diameter of the disc changes, this will remove the disc feeding plate.
<By adjusting the movement by half the distance of the diameter difference using the movement adjustment table, in other words, when the diameter becomes larger, the disk feeding plate can be moved farther from the axis of the disk cartridge than the adsorption mechanism and bottle cap supply section. If the diameter becomes smaller, the disk is fed out by the disk feeding plate by adjusting the movement in the direction closer to the suction mechanism and the bottle lid supplying unit with respect to the axis of the disk cartridge. The center of the disc is placed at the center of the suction mechanism, and the change in diameter of the disc can be handled by an extremely simple operation of adjusting the movement of the disc feeding plate using the movement adjustment table. be.

A suction mechanism 29 is disposed above the j1 rose supply section 20 at the right end of the bottle cap transfer passage 14. This suction mechanism 29 includes a stand 30 erected from the machine frame 2;
A pair of upper and lower brackets 31, 3 attached to the stand 30
2. Large and small 2 (11i1 pneumatic cylinders 33 and 34 attached to the upper bracket 32, and lower bracket 31,
It consists of a spindle 35 supported vertically so as to be movable up and down, and a vacuum suction cup 36 is provided at the lower end of the spindle 35, while the upper end of the spindle 35 is connected to a piston 37 in a small pneumatic cylinder 34, and the spindle 35 is 35 is biased in the upward direction by a spring 40 fitted thereto, and pressed into contact with the member 39 attached to the piston 38 in the large pneumatic cylinder 33, thereby the spindle 3
5 is configured to be moved up and down slightly by a small pneumatic cylinder 34, and to be greatly lowered by the downward protruding movement of the piston 38 in the large pneumatic cylinder 33, and then raised by the force of the spring 40.

In addition, inside the spindle 35, there is a suction @3 at the lower end of the spindle 35.
A through hole 4 for communicating the inside of 6 with a vacuum source (not shown)
1 is provided, and reference numeral 42 in the figure is for discharging the bottle cap A after the disk B has been inserted in the bottle cap supply section 20 along a groove 43 extending perpendicularly to the bottle cap transfer passage 14. A discharge piece 42 is shown, which discharge piece 42 is configured to reciprocate in a pneumatic cylinder 44 .

In this configuration, when handling a bottle cap A having a diameter (D), the distance between the guide members 4 and 5 and the width distance in the +ta cup transfer passage 14 are adjusted by moving the guide member 4 using the left carriage 8. By adjusting the movement of the guide member 5 and stopper plate 3, set the diameter (D) to match the diameter (D) of the bottle cap A (slightly larger than the diameter (D) so that the bottle MA can be transferred smoothly), and A disk car containing a disk B that matches A) - the ridge 24 is installed, and the axis 4 of the spindle 35 in the suction mechanism 29 from the positioning piece 21
5 by adjusting the movement using the movement adjustment table 11 to which the positioning piece 21 and the disk threading plate 25 are attached.
) Set it so that it is half the diameter (D) to the 1-bar cup.

Then, when the push-out piece 19 in the bottle cap transfer passage 14 is moved toward the bottle cap supply section 20 by the pneumatic cylinder 17, the bottle cap A on the conveyor belt ↓ is moved to the lower part of the spindle 35 in the suction mechanism 29. At the same time, the disc reel plate 25 is fed concentrically to its pneumatic cylinder 2.
When the spindle 35 of the suction mechanism 29 is moved forward toward the suction mechanism 29 at step 6, the spindle 35 of the suction mechanism 29 is moved forward with only one disk B in the disk cartridge 24 in the recess 28 on the upper surface of the disk threading plate 25. It is rolled out directly below (Figure 9). Then, the spindle 35 is lowered by the operation of the small pneumatic cylinder 34, sucks the disk B on the upper surface of the disk hoisting plate 25 with the suction cup 36 at the lower end, and then rises. Next, when the disk hoisting plate 25 retreats to the lower part of the original disk cartridge 24, the spindle 35 with the disk B suction-locked thereon as described above is previously supplied to the lower part by the operation of the large pneumatic cylinder 33. The spindle 35 descends toward the inside of the bottle lid A and inserts the disk B into the bottle lid A. When this insertion is completed, the spindle 35 releases the suction lock of the disk B and then rises, while at the same time preventing the insertion of the disk B. The finished bottle cap A is sent out of the machine from the discharge groove 43 by the protruding movement of the discharge piece 42, and the disc B is inserted into the bottle cap A by repeating the operation described in item 1 below.

Next, when handling a bottle cap A' having a small diameter (D'), as shown in FIGS. The distance is set according to the diameter (D') of the bottle cap A' by adjusting the movement of the guide member 4 by the left carriage 8, and by adjusting the movement of the guide member 5 and the stopper plate 3. Disc cartridge 24' containing disc B' compatible with
At the same time, the positioning piece 21 and the disk hoisting plate 25 are moved forward by the movement adjustment table 11 to which they are attached, so that the suction mechanism 29 is removed from the positioning piece 21.
The distance to the axis 45 of the spindle 35 is set to be half the diameter (D') of the bottle lid A'. In other words, when the diameter of the bottle cap decreases from (D) to (D'), the positioning piece 21 and the disc thread plate 25 are moved to the disc thread by a distance that is half the diameter difference (D-D'). The movement of the plate 25 is adjusted using the movement adjustment table 11 in a direction toward the suction machine Wi29.

Then, when the disk reeling plate 25 moves forward, the center of the disk B', which is ejected from the disk cartridge 24' while being fitted into the recess 28 on the upper surface thereof, coincides with the axis 45 of the spindle 35. Because it comes to that,
After the disc B' is attracted to the suction cup 36 at the lower end of the spindle 35, as the spindle 35 descends, it is inserted concentrically into the bottle lid A' which has been supplied in advance directly below the disc B'.

Further, when the diameter of the bottle lid becomes larger, the disk threading plate 25 is moved by the movement adjustment table 11 to which it is attached, so that the suction mechanism 29 and + [lid supply unit 2
By adjusting the movement in the direction away from 0, the center of the disk fed out from the disk cartridge 24 by the disk feeding plate 25 can be aligned with the axis 45 of the spindle 35 in the suction mechanism 29, and the center of the disk can be aligned with the axis 45 of the spindle 35 in the suction mechanism 29. It can be inserted in any shape.

That is, according to the present invention, a change in the diameter of the disk can be handled by an extremely simple operation of adjusting the movement of the disk threading plate using the movement adjustment table.
Its operation is extremely simple, and there is no need to replace the leaf spring that locks the disc with the two parts of the bottle cap each time the diameter of the disc changes. This allows insertion of the disc into the bottle lid.

In addition, although the description of the above embodiment shows the case where the pneumatic cylinder 26 is used as the reciprocating mechanism for the disk hoisting plate 25, the reciprocating mechanism for the disk hoisting plate 25 is not limited to this, and other types may be used. It goes without saying that a reciprocating mechanism may be used, and a mechanism other than the above embodiment may also be used as a means for supplying the lid Δ to the bottle lid supply section 20.
