DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the article delivery device according to the present invention will now be described with reference to the drawings.

1 and 2, A is an article delivery device,
For example, an article b such as a container for filling and packaging a fluid is continuously supplied to the next step one by one.
The guide member 3, the article delivery belt 4, the inclined support member 5, the rotary shaft 6, and the conveying disc 7 are basically configured.

The pillar 2 is erected substantially vertically to the machine body 1 and has a hollow interior.

The guide body 3 is formed in a cylindrical shape having a predetermined diameter, and is supported by the mounting member 8 on the outer periphery of the column 2 so as to rotate substantially horizontally. Guide surface 3a for restricting the centrifugal force of the article b by 7
Is formed substantially vertically, and the driving means M described later is used.
Is continuously rotated in one direction.

Further, in the vicinity of the bottom of the guide body 3, a gap is formed between the outer peripheral edge of the conveying disc 7 described later, so that when the shape of the article b is small, as shown in FIGS. 1 and 4. In some cases, an inclined or arcuate correction surface 3b whose lower part is extended inward may be provided, but depending on the article to be processed b, it may be a straight substantially vertical shape that coincides with the guide surface 3a.

The above-mentioned article delivery belt 4 is attached in an annular shape so as to project outward at the upper peripheral edge of the guide body 3, and rotates integrally with the guide body 3 in a substantially horizontal state.
As shown in FIG. 3 (a), the upper surface may be formed in the same horizontal shape as in the rotating state, but preferably, as shown in FIG. 1 and FIG. By forming the inclined surface 9 which is inclined downward, the article b on the article delivery zone 4 is supported by the receiving guide 10 delegated to the outer peripheral portion of the article delivery zone 4 to form the article b. It is possible to improve the stability of the placement of the guide and prevent it from dropping into the guide body 3 again.

Further, as shown in FIG. 6A, even when the containers b, which are articles, are transferred so that their mouths face each other, the respective containers b, b are moved to the receiving guide 10 side by the inclined surface 9 thereof. The phenomenon in which the positions are biased to be stable and the mouths are misplaced (the directions are sparse and the whole is not in contact with the receiving guide 10) is eliminated, and the takeout member 20 in the subsequent step is shown in FIG. ),
It is possible to prevent the containers b from being caught in each other, and the discharge member 20 is smoothly discharged.

The above-mentioned inclined support 5 is formed in a disc shape so that it can be fitted into the inside of the guide 3, and its base is fixed to the upper part of the column 2, and its top 5a is an article. It is provided so as to be close to the side of the delivery band 4 and be inclined so that the bottom portion 5b is close to the lower side of the guide body 3.

The tilt angle of the tilted support 5 can be arbitrarily selected according to the shape and size of the article b to be processed. For example, the tilt angle of the top support 5a is 10
Provided around 15 °, and those located on the bottom 5b side are provided around 15 °.

The rotary shaft 6 is rotatably inserted in the support column 2 and is continuously rotated in one direction by a driving means M described later.

The above-mentioned transport disc 7 is used to place randomly loaded articles b and continuously transfer them from the container reservoir at the bottom to the delivery position at the top. The center of rotation is attached and placed on the tilt support 5 by its own weight, and the upper part of the tilt support 5 is rotatably slid.

The transport disc 7 is provided at least in the vicinity of the transport body 7a on which the article b whose peripheral portion abuts or approaches the inner circumference of the guide body 3 is placed, and the rotation center portion. The mounting body 7b is flexible in the vertical direction.

The flexible mounting body 7b is made of a material which allows the carrier body 7a to bend in the vertical direction according to the inclination change at each rotation angle in the circumferential direction of the inclined support body 5. .

The mounting body 7b capable of performing this action is preferably made of, for example, a rubber material, and when this rubber material is adopted, it is formed in a disk shape which is integrated with the above-mentioned carrier body 7a.

This rubber material carrier 7a gives appropriate friction to the article b placed on the upper part thereof, so that the article b is moved in the middle of the conveyance from the bottom to the top, and the article b is moved by its own weight, In addition, a soft synthetic resin or the like that is prevented from falling due to vibration and can obtain appropriate friction can be used.

The carrier 7a made of a hard material
If necessary, a bar-shaped non-slip member (not shown) may be provided on the upper surface so as to project.

In addition to the rubber material, the flexible mounting body 7b has a chain-like body formed of synthetic resin, metal or the like, or the outer periphery of the rotating shaft 6 at intervals such that the article b does not drop. It can also be configured by a soft rod extending in a radial direction or a rod that can be rotated by a shaft support to the outer peripheral portion of the rotary shaft 6 or the like. As described above, the carrier 7a is inclined and supported. Any structure can be selected as long as it can bend in the vertical direction according to the inclination change at each rotation angle in the circumferential direction of the body 5.

Incidentally, if a synthetic resin plate 11 having a small friction coefficient is adhered to the portion of the lower side of the conveying disc 7 which is in contact with the inclined support 5 over the entire surface or at intervals, the conveying disc 7 can be formed. A smooth movement can be expected in the rotation sliding of 7.

The drive means M described above uses a drive member 12 such as a conventional motor with a speed reducer to drive both the guide body 3 and the transfer disk 7 of the rotary shaft 6 in an interlocking manner. Then, the linking member 1 such as a chain from the driving member 12
3 is linked to an intermediate shaft 14 erected on the machine body 1, and the intermediate shaft 14 is linked to a chain wheel 15 provided on the attachment member 8 of the guide body 3 and a chain wheel 16 attached to the rotary shaft 6, respectively. 17, 18 are linked.

The rotation speed ratio between the guide body 3 and the transport disc 7 is such that the supply of the article b transferred to the article delivery zone 4 is increased,
Alternatively, a speed ratio of about 3: 4 is preferable when performing early, but it is usually performed at 1: 1 (the speed ratio is not limited), and both speed adjustments are conventional. A transmission such as an inverter is used.

Although not shown, the drive means M can rotate the guide body 3 and the conveying disc 7 by separate drive members, and the speeds of the drive members can be adjusted individually. A speed converting means is provided.

The apparatus A and method of the present invention configured as described above have the following operations.

When a large number of articles b are randomly placed on the conveying disc 7 by a feeder (not shown) or the like, the articles b are placed and accumulated on the conveying disc 7 and The article b located at the outer peripheral portion, that is, the bottom portion is the guide member 3
It is surrounded by the guide surface 3a or the correction surface 3b, and is always positioned on the transport disc 7.

In this state, when the transport disc 7 and the guide body 3 are respectively rotated by the drive means M, the transport disc 7 placed by its own weight on the inclined support 5 mounted at a predetermined inclination, Along with the rotational movement, the article b located at the lower portion of the conveying disc 7 is gradually raised and is subjected to the centrifugal force of the rotation thereof to come into contact with the guide surface 3a which is the wall portion of the guide body 3, The rising end of this transport disc 7 is reached.

Then, the article b, which has moved to the upper edge portion of the guide body 3 and the regulation of the centrifugal force is released by the guide surface 3a of the guide body 3, is an article attached to the upper peripheral edge portion of the guide body 3. The article b is transferred to the delivery zone 4 by a centrifugal force, and the transferred article b is transported to the next process by the article delivery zone 4 by a predetermined feeding section, that is, the takeout member 20.

At this time, since the transport disc 7 is attached to the substantially vertical rotary shaft 2 by the flexible mounting body 7b, the transport body 7a located at the bottom of the guide body 3 is
Along with the rotational movement, the mounting body 7b bends from the bottom position along the inclined support body 5 that is inclined upward to gradually change the inclined posture to the horizontal direction, and further to change to the upward direction. When the carrier 7a reaches the top of the guide body 3, the mounting body 7b bends along the tilt support body 5 that is inclined downward from the top position due to the rotational movement of the carrier 7a, and the tilted posture gradually becomes horizontal. Change, and then change to the descending direction.

Since the transport disc 7 is bent in the up-and-down direction to change in the wavy state of the mounting body 7b, even if the rotation axis 6 of the rotation center is a substantially vertical axis, this movement is not hindered. .

If the article delivery band 4 on the upper part of the guide body 3 is formed with an outward downward inclined surface 9, the article b transferred from the peripheral portion of the conveying disc 7 is shown in FIG. 3 (b). And FIG.
As shown in (a), it moves outward along the inclination of the inclined surface 9 and abuts and is supported by the receiving guide 10.
The mounting posture of the article b is always maintained in a stable state in which the entire side surface of the article b is in contact with the receiving guide 10, and the article b is not dropped again to the transport disc 7 due to the unstable posture.

By changing the tilt angle of the tilt support 5 as shown in FIG. 5, it is possible to change the tilt state of the transport disk 7 placed on the tilt support 5. Therefore, the article b to be processed can be arbitrarily exchanged and changed according to the shape, size and type of the article b.

[0045]

According to the present invention configured as described above, since the conveying disc for sending the article from the bottom to the top is constituted by the flexible mounting body, the rotating shaft of the conveying disc is a machine body. Since it can be mounted substantially perpendicular to the drive shaft, the drive system can be configured with a simple structure for driving the rotary shaft, and reliable drive can be provided.

Further, since the transport disc is configured to be placed on the inclined support body by its own weight, the change in the angle of the inclined support body is combined with the action of the flexible mounting body described above. , The tilt angle can be converted arbitrarily.

By forming a downward sloping surface in the outer peripheral direction in the article delivery belt, the loading posture of the article transferred to the article delivery belt is stabilized, and the adverse effect such as biting when transferring the article to a subsequent process is adversely affected. Don't give. It has special effects such as.
