Description

  The present invention relates to a rotary container transfer device that holds and transfers a container, and in particular, a rotary container that transfers a container in a container processing apparatus such as a rinser that cleans various containers and a filler that fills the container with liquid. The present invention relates to a transfer device.

  The conventional rotary container transfer device is manufactured according to the shape of the container, especially the thickness, and a dedicated rotary container transfer device is prepared for each lot. For the replacement, it was necessary to completely replace the dedicated rotary container transfer device. For this reason, a method has been proposed in which the rotary container transfer device can be divided and replaced to facilitate replacement of the heavy rotary container transfer device (see, for example, Patent Document 1).

Yes. The first holding unit 1 holds the upper stage of the bowl B2 that the holding means H transfers from the rear side in the transfer direction of the container W (hereinafter referred to as the bowl B2), that is, the left side of the arrow shown in the drawing. Moreover, the 2nd holding | maintenance part 11 hold | maintains the lower stage of the cage | basket B2 to transfer.
That is, the first holding unit 1 is handled by the first upper rotating body 2 and the first lower rotating body 3, and the second holding unit 11 is handled by the second upper rotating body 12 and the second lower rotating body 13.
The outer shape of the first upper rotating body 2 is such that four arm portions 2a are extended in a star wheel shape here. A hole 2c is formed at the center of the first upper rotating body 2, and a first internal gear 2f is formed in a segment gear shape on the inner peripheral surface thereof. The first pinion gear 4 rotatably supported by the shaft meshes with the first internal gear 2f.

Similarly, on the outer shape of the first lower rotating body 3, four arm portions 3a are extended in a star wheel shape, and a hole 3c is formed at the center. A second internal gear 3f is formed in a segment gear shape at a position facing the first internal gear 2f on the inner peripheral surface of the first lower rotating body 3, and a second pinion gear 5 rotatably supported by the second internal gear 3f The gear 3f meshes with the first pinion gear 4.
Here, the “segment gear shape” refers to a gear provided with a missing portion that is not an internal gear formed over the entire circumference.

  As shown in FIG. 3A, a rotary shaft 14 rotated by a drive source (not shown), a flanged sleeve 15 that rotates together via a key 14a disposed at the upper end of the rotary shaft 14, and A bolt 21 for fixing this to the rotating shaft 14 via a washer 21a, an oval plate 17 on the flange portion, and a ring-shaped nut ring 16 below the flange portion are sandwiched from above and below. And fixed to the flange portion by two bolts 24 (see FIG. 3B). Then, the first upper rotating body 2 and the first lower rotating body 3 of the first rotating body are placed on the oval plate 17, and the first upper rotating body 2 and the first lower rotating body 3 are placed by the two first connecting pins 6. 2 The upper rotating body 12 is connected. Similarly, the lower end portion of the second connecting pin 7 is fixed to the second lower rotating body 13, and the bolt 26 is provided at the upper end portion of the second connecting pin 7 through the long hole of the second upper rotating body 12. It is screwed into the screw hole and fixed. Further, serrations are applied to the outer peripheral surface of the head of the bolt 26, and a lever 19 is attached to the serration.

As a result, as shown in FIGS. 2 and 3, when the first holding portion 1 constituted by the first upper rotating body 2 and the first lower rotating body 3 is rotated in the opening direction, the first upper rotating body 2 The rotation is transmitted to the first pinion gear 4, the rotation of the first pinion gear 4 is transmitted to the second pinion gear 5, and the first lower rotator 3 is rotated from the second pinion gear 5, so that the second upper rotator is rotated. Similarly, when the first upper rotating body 2 and the first lower rotating body 3 are also rotated in the direction to close the first upper rotating body 2 and the first lower rotating body 3, the second upper rotating body 12 is also rotated. Similarly, the second lower rotating body 13 is also rotated by the same amount in the closing direction.
That is, the rotation of the first upper rotator 2 and the second upper rotator 12, the first lower rotator 3 and the second lower rotator 13 is rotated when one is rotated in the clockwise direction in plan view. Turns evenly in the opposite direction.

  FIG. 3B is a cross-sectional view taken along the line BB shown in FIG. As shown in FIG. 3B, the inner peripheral surfaces of the first upper rotating body 2 and the second upper rotating body 12 are pivotally supported by bearings 23 and 23 fitted in bolts 24, respectively. Yes.

Here, with reference to FIG.2, 3, the setup change procedure of the rotary container transfer apparatus 10 of the bowl B2 is demonstrated. As shown in FIG. 2, for example, a case is assumed where the size of the container W (ＷB2) is increased to that of the container W (壜 B3). In the case of this round gore, the block 9 is common to all sizes, so that the block 9 need not be replaced.
The two connecting pins 7 are released by loosening the two levers 19.
Therefore, the flange B3 is inserted into the holding portion H, one of the blocks 9 is gripped, and a predetermined gap is provided between the arcuate guide 8 shown in FIG. Is rotated in a closing direction until a predetermined gap is reached. Then, the two levers 19 are tightened to finish.

  FIG. 4 is a plan view of a rotary container transfer device for square hooks. As shown in the lower part of FIG. 4, the block 9 is replaced with a right block 9 b and a left block 9 c, so that the rotary container transfer device 10 for the basket B <b> 2 shown in FIG. It can be easily changed to the rotary container transfer device 10 '.

Here, a procedure for changing the rotary container transfer device 10 for the round rod B2 to the rotary container transfer device 10 'for the square rod B4 will be described. As shown in FIG. 3, the blocks 9 and 9 for the round rod B2 attached via the ball plunger 9d are pulled out and removed, and then the right block 9b for the square rod B4 as shown in FIG. Is inserted into the positioning pin 2g and the retaining pin 2h of the first upper rotating body 2 and the second upper rotating body 12, and fixed through the ball plunger 9d.
Further, the left block 9c for the square hook B4 is inserted into the positioning pin 3g and the retaining pin 3h of the first upper rotating body 2 and the second upper rotating body 12, and fixed through the ball plunger 9d.

As mentioned above, although the form which has the 1st holding | maintenance part 1 holding the upper part of a container and the 2nd holding | maintenance part 11 holding the lower part of a container as a holding means was demonstrated, the thickness of a container with respect to the height of a container is demonstrated. If the container is not easily toppled due to a large ratio or the like and the stability is sufficient, the second holding portion 11 and the first connection pin 6 and the second connection pin 7 related thereto are not provided. A rotary container transfer device (not shown) having a simplified structure that holds the container only by the holding unit 1 can be used.
Further, depending on the height and shape of the container, a third holding portion or a higher holding portion may be provided.
