The present invention relates to an article transport device capable of

[0002]

2. Description of the Related Art Nowadays, in the case of transferring a container to a processing machine for filling a liquid or powder into the inside of a cylindrical container or the like, the container is also supplied in response to the automation and speeding up of the processing machine. There is a demand for continuous and high-speed equipment, and as a technology for meeting these demands, Japanese Patent Publication No. 46-11726.
Japanese Patent Publication No. 1-45701 proposes a container aligning and delivering / discharging device.

In these devices, containers are arranged in a predetermined direction in a single row, a large number of them are stored in a plurality of rows of stock chutes and are on standby, and the required number of containers is intermediate based on predetermined control. It is sequentially and continuously supplied to a transfer means such as a screw conveyor linked to the processing machine via a feed conveyor.

However, as shown in FIG. 4 (a), the feed conveyor 30 has a structure in which an endless chain 32 having a number of bottle guides 31 attached thereto is stretched. When the container 34 moves to the reversal part y by 33, the bottle guide 31 of the feed conveyor 30
Has a fixed pitch in the straight line portion x, but the pitch is widened by the angle of rotation thereof. Therefore, as shown in FIG.
When the container 34a is damaged or crushed by interfering with a, the container 34a is pushed out of the container 36 of the screw conveyor 35, and the container 34a is pulled from the container (hakama) of the container 34a. When the container is pulled out of the conveyor and squeezed out of the conveyor, the container is damaged by being caught between the screw and the hakama, and at the same time, the hakama is also collapsed to cause a problem of being caught in the screw.

Therefore, in order to eliminate this drawback,
For example, as shown in FIG. 4 (b), the feed conveyor 30 to which the bottle guide 31 is attached is provided with an escape slanting portion 38 that gradually separates from the screw conveyor 35 from the position where the stock chute 37 has passed. This prevents the bottle guide 31 from interfering with the container 34.

Further, in the case shown in FIG. 4 (c), the bottle guide 31 whose posture is corrected by the contact of the roller 38 with the cam plate 39 is rotatably attached to the chain 32 of the feed conveyor 30.
By supporting it 40 times, the bottle guide 31 is prevented from interfering with the container 34 at the reversing portion y of the conveyor 30.

However, the former device requires a relatively long distance for the escape slanting portion, which increases the size of the machine as a whole and increases the size of the entire slanting portion. Since extra parts are required, the cost is increased, and moreover, the factory space is wasted for installing this device.

[0008] In the latter device, various parts for correcting the posture of each bottle guide mounted on the feeding conveyor are provided, and the manufacturing cost is increased because of using highly accurate parts in a narrow space. Along with
Since sufficient durability cannot be obtained, frequent maintenance was required. There were various problems such as.

[0009]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and in a screw conveyor, at the downstream side of the auxiliary article transfer means, the accommodating portion thereof is provided as the auxiliary article transfer means. By forming the linear transfer corresponding parts of the same pitch with the equal pitch and the inverting corresponding parts of the sub article transfer means with unequal pitch, damage of the product caused by excessive pressing or biting of the screw conveyor may occur. An object of the present invention is to provide an article transporting apparatus that can manufacture a transporting apparatus that does not have a compact size at low cost.

[0010]

Means for Solving the Problems The means of the present invention for achieving the above-mentioned object is an article supply means having an aligning portion for accommodating a plurality of articles in a column, and feeding the articles one by one from the lower portion thereof. A screw conveyor provided with a large number of accommodation parts for the article, which is provided below the means, is provided between the article supply means and the screw conveyor, and receives the article dropped from the alignment part to the sub-accommodation part, In an article transporting device comprising an auxiliary article transfer means that moves in synchronism with the screw conveyor and drops into the accommodation portion of the screw conveyor, the auxiliary article transfer means includes a rotation shaft that is erected before and after the article supply means, and The screw connector includes an endless linking member suspended on a rotating shaft, and a pushing piece protruding from the linking member at predetermined intervals to form the sub-accommodating portion. (A) is a configuration of an article transporting device in which the accommodating portion is formed such that the linear transfer corresponding portions of the sub article transferring means are formed at equal pitches and the reversal corresponding portions are formed at unequal pitch on the downstream side of the sub article transferring means. .

[0011]

The present invention configured as described above has the following effects.

When a plurality of articles are accommodated in a line in the aligning section of the article supplying means, the screw conveyor and the sub article transferring means are driven, and the articles are fed out one by one from the lower part of the aligning section, the sub article transferring means is provided. The articles are accommodated in the sub-accommodating section and the accommodating section of the screw conveyor and conveyed in one direction in synchronization.

Further, on the downstream side of the transfer of the above-mentioned auxiliary article transfer means, the accommodating parts of the screw conveyor are formed at equal pitches up to the corresponding part for linear transfer, so that the parts move sequentially at a constant interval.

However, the articles that have reached the inversion corresponding portion of the sub-article transfer means are the articles that are stored in the front accommodating section of the screw conveyor due to the expansion of the rotation angle of the pushing piece of the sub-article transfer means. Although it tries to push it out in the rotation direction, since the inversion corresponding portions are formed with an unequal pitch, that is, a wide pitch, the screw conveyor driven synchronously extends the transfer distance of one rotation and The article can be stably transferred without interfering with the pushing piece.
