Abstract

PURPOSE:To aim at the promotion of smoothness in goods transfer, by installing a fixed cam, which decreases a distance with the center of a rotary shaft gradually toward the downstream side, and a goods guide surface being formed likewise both in a space ranging from an inlet part to an outlet part. CONSTITUTION:A groove cam 22 is formed so as to decrease a distance with the center O of a rotary shaft 10 along a route 24 gradually toward the downstream side from a part 22 corresponding to an inlet part. Since a horizontal distance between an axial center 15a of a cam 15 and an axial center 23b of a cam roller 23 is constant, at the route 24, the cam roller 23 rotates at somewhat larger velocity than the rotation velocity of the cam 15. In addition, a distance l in both centers between a bottle guide surface 18a and the rotary shaft 10 is made up so as to gradually decreased toward an outlet part. Therefore, the press-feed velocity of a bottle 1 by feed fingers 16a and 16b is gradually slowed down while it shifts from the inlet part 20 to the outlet part 21.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an article transfer device, and more particularly, the present invention relates to an article transfer device, and more particularly, a device for transferring an article such as a bottle from an inlet to an outlet along a guide surface. The present invention relates to a transfer device that transfers data while moving.

(Prior Art) Inspection and filling of articles such as glass bottles are carried out using a recess (see Fig. 1, 5a) formed along the periphery of a turret (see 5 in Fig. 1) that continuously rotates these objects. ), and is often carried out while being transferred. In this case, the articles are transferred from the inlet side belt conveyor to the turret via the inlet star wheel (see 4 in Figure 1), and after being inspected or filled, they are transferred to the outlet side via the outlet star wheel. It is often transferred to a conveyor and transported to the next process.

Problems to be Solved by the Invention When using a conventional starwheel, the articles move at the same speed on the belt conveyor, starwheel, and turret. However, for example, it may be desirable to make the transfer speed on the belt conveyor smaller than the transfer speed on the turret.

In the turret, moving at high speed increases the speed of inspection, etc., and since bottles and other objects are engaged in recesses,
This is because it is difficult to topple over even at high speeds, but when conveyed by a belt conveyor, there is usually nothing to support it, so it becomes easier to topple over at high speeds.

Therefore, in such a case, it is desirable to use a transfer device capable of decelerating or increasing speed in place of the conventional star wheel υ. However, in the past, there has been no suitable transfer device with such performance.

(Object of the Invention) An object of the present invention is to provide a transfer device capable of transferring an article from a first conveying device to a second conveying device while changing speed, that is, decelerating or increasing speed. .

(Structure of the Invention) In one device, the device includes a rotating shaft, a portion surrounding the rotating shaft, and extending from a portion corresponding to the inlet portion downstream to a portion corresponding to the outlet portion. , a fixed cam whose distance from the center of the rotating shaft gradually decreases (or increases) toward the downstream side, a cam 7 lower that engages with the cam, and a rotating shaft fixed to the rotating shaft. A disk, a column mounted swingably relative to the rotary disk and parallel to the rotation axis, and a feed finger fixed to the column for pushing the article along the guide surface. The present invention provides an article transfer device, wherein the guide surface is formed in an arc shape such that the distance from the center of the rotating shaft gradually decreases (or increases) toward the downstream side. be.

(Example) The present invention will be described below with reference to drawings which are examples.

(Structure) FIG. 1 shows an example of a device to which the transfer device of the present invention is applied, in which a glass bottle 1 is placed on an entrance side conveyor 2 and conveyed in the direction of arrow A. Near the downstream end of the conveyor 2, after being aligned at regular intervals by the screw conveyor 3, it moves to the star wheel 4,
It engages with the recess 4a and is conveyed in the direction of arrow B, moves to and engages with the recess 5a of the turret 5, and is then conveyed by the turret 5 in the direction of arrow C. While being transported by the turret 5, it is inspected or filled by an inspection device or filling device (not shown). The conveyance speed by the turret 5 is, for example, 70 m.
/minute.

The bottles that have been inspected or filled are conveyed by the transfer device 6 in the direction of the arrow and decelerated to, for example, 50 m/min), then transferred to the belt conveyor 7 and conveyed in the direction of the arrow E at the reduced speed. be done.

As shown in FIGS. 2 and 3, the transfer device 6 is
A vertical rotating shaft 10 that rotates at a constant speed in the direction of the arrow by a drive mechanism (not shown) provided below, a horizontal fixed plate 11 fixed to a support (not shown) and pivotally attached to the upper part of the rotating shaft 10; Rotating shaft 1 so that it is located below
0, a central horizontal rotary disk 13, a lower horizontal rotary disk 14, and a plurality of rotary disks 12, 13, and 14 that are rotatably supported by the rotary disks and arranged at equal intervals in the circumferential direction. (6 in the figure) vertical columns 15, an upper feed finger 16a for pushing the bottles 1 fixed to the lower part of each vertical column 15, and a lower feed fin of 116 bl.
Dead grate 1 along which the bottle 1 is pushed along its upper surface
7, and comes into contact with the body wall portion 1a of the bottle l being pushed,
A guide 18 having a guide surface 18a for guiding the bottle 1 from the inlet part 20 to the outlet part 21 is provided. The main portions 16x of the feed fingers 16a, 16b are preferably made of plastic.

A circumferential grooved cam 22 is formed on the lower surface of the fixed platen 11. Further, a shaft 23a of a cam roller 23 that engages with the grooved cam 22 is fixed to the upper rotary disk 12. A plurality of cam rollers 23 (six in the figure) are provided inside the column 15 in the radial direction corresponding to each column 15, and the axial center 23b of each cam roller 23 corresponds to the axial center 15& of the column 15.
The cam roller 2 when in the intermediate part 20 and the exit part 21
The portions 22a and 22b where No. 3 is located are respectively referred to as a portion corresponding to the inlet portion and a portion corresponding to the outlet portion. The distance between the grooved cam 22 and the center 0 of the rotary shaft 10, and therefore the distance d between the center line 22x of the grooved cam 22 and the center 0, corresponds to the outlet portion downstream from the portion 22a corresponding to the inlet portion. In the path 24 up to the portion 22b, it is determined to gradually decrease toward the downstream side, or in the case of FIG. 2, to decrease linearly with respect to the rotation angle.

The guide surface 18a of the guide 18 is also arc-shaped so that the distance t between the guide surface 1-8a and the center 0 of the rotating shaft 10 gradually decreases from the inlet section 20 to the outlet section 21, that is, toward the downstream side. It is stipulated in

Further, each feed finger 16a, 16b is fixed to each column 15 so that the angle θ between its extending direction and a plane connecting the axis 15m of the corresponding column and the axis 23b of the cam roller is constant. . This angle θ° is determined at the inlet portion 20 by the feed fingers 16a, 16b.
The bottle 1 is placed between the guide surface 18a and the feed fingers 16a and 16b so that the bottle 1 can be pushed by the feed fingers 16a and 16b.

(Function) At the same time as the bottle 1 enters the turret 5 and the input slot 20,
At the inlet section 20, there is a feed finger isa'.

The rotation of the rotary shaft 10 is timed so that the bottle 16b' reaches the bottle 1, comes into contact with the bottle 1, and can be pushed. As the rotating shaft 10 rotates, the column 15 revolves at a constant speed. □ By the way, the grooved cam 22 is formed so that the distance from the center 0 of the rotation axis gradually decreases along the path 24 toward the downstream side from the part 22a corresponding to the inlet part. Since the horizontal distance between 1'5a and the axis 23b of the cam roller is constant, the cam roller 23 revolves on the path 24 at a speed slightly higher than the revolution speed of the column 15.

That is, in the portion 22a corresponding to the inlet portion, the cam roller 23 is far behind the column 15 in the circumferential direction, but in the portion 22b corresponding to the outlet portion, the cam roller 23 is far behind the column 15 in the circumferential direction. In the case of FIG. 2, the feed fingers 16
The column 15 adjacent to the upstream side is inserted into the recess 25 formed on the rear surface of the columns a and 16b.

Therefore, the feed fingers 16a, 16b
While pushing the bottle 1 from the column 1 to the outlet 21, the column 1
5 in the direction of arrow F, in the opposite direction to the rotation direction of the claw. Correspondingly, the speed at which the bottle 1 is pushed becomes gradually smaller while moving from the inlet section 20 to the outlet section 21.

Furthermore, the bottle 1 is pushed by the feed fingers 16a and 16b while contacting the guide surface 18a, and the distance t between the guide surface 18a and the center 0 is
1, so the distance between the center p and the center 0 of bottle 1 gradually decreases as it revolves, so the trough increases. The transport speed of the bottle 1 decreases.

(Continuation of configuration) The embodiment of the transfer device that transfers the article while decelerating has been described above, and the distance from the center of the rotation axis gradually increases toward the downstream side when moving the grooved cam in the section corresponding to the path 24. In addition, by forming the guide surface so that the distance from the center of the rotating shaft gradually increases toward the downstream side, the outside of the fish body is configured similarly to the device 6, so that the article can be transported while increasing the speed. Transfer device (
(not shown) can be obtained. By changing the direction of this device and disposing it in place of the star wheel 4 shown in FIG. 1, the conveyance speed of the entrance side conveyor 2 can be made smaller than before.

The present invention is not limited to the above embodiments,
For example, the article may be a metal can or the like.

(Effects of the Invention) The device of the present invention is capable of transferring articles sent one after another at regular intervals from the first conveying device to the second conveying device while changing the speed, that is, decelerating or increasing the speed. It has the effect of being able to do it.
