Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for collecting and aligning transported articles in a single line.

A device for sorting canned goods, bottled goods, etc. that have been conventionally sent on a transfer conveyor into two lines and then combining them into one line is well known, as seen in, for example, Japanese Utility Model Application No. 51-22371.

However, the above-mentioned known devices require means for dividing the objects to be processed on the conveyor and means for destroying the bridging phenomenon, and these also require large-scale equipment.

Further, there was a problem that it was not possible to process objects to be processed that were transferred in two or more rows.

In view of this, in the present invention, the objects to be processed that are sent onto the transfer conveyor are sent to the end by the belt movement of this conveyor, are gradually aligned in decimal rows by hitting the left and right alignment guide members, and are arranged in decimal rows at the final exit. The object of this invention is to provide an apparatus for collecting and arranging transferred articles in a single line so that the articles are arranged in a line and sent out.

The present invention will be explained below with reference to an embodiment shown in the drawings.

The device for collecting and arranging transferred articles in a single line according to the present invention includes:
A conveyor 1 for transporting objects to be processed, and a conveyor 1 at the end of the conveyor 1, one on the downstream side and the other on the upstream side, supported by shafts 3 and 4 on the machine frame 2, so that the width becomes narrower toward the downstream side. A pair of left and right alignment guide members 5, 6, and crank rods 9, 10 of cranks 7, 8 rotatably supported on one side of the machine frame 2 are connected to intermediate portions of the alignment guide members 5, 6, respectively. It is comprised of a power transmission mechanism 11 configured to swing each alignment guide member 5, 6.

As shown in FIG. 1, the conveyor 1 for transferring the workpiece 12 is configured to move the workpiece 12 from the right to the left, and the workpiece 12 is moved from the right to the left.
2 in a line.

As shown in the first diagram, this transfer conveyor 1 is composed of a number of rows of endless belts 1a, 1a...
The endless belt 1a' located in the center and extending into the passage 13 is configured to be moved at a faster speed than the other endless belts 1a, 1a..., and carries the workpieces 12 in the center row. It is designed to feed smoothly into the passage 13.

The alignment guide members 5 and 6 are preferably the third alignment guide members 5 and 6.
As shown in the figure, it is composed of guide rollers 15, 15, . Ru.

The power transmission mechanism 11 has a horizontal shaft 16 connected to a drive source (not shown), as shown in a side cross section in FIG.
When the rotation of the bevel gear 17 is transmitted to the vertical bevel gear 18, the vertical shaft 19 directly connected to the bevel gear 18 rotates, and the cranks 7 and 8 fixed at the upper part of the vertical shaft 19 further rotate. It's summery.

Crank rods 9 and 10, one end of which is eccentrically attached to the upper part of the cranks 7 and 8, are attached to the intermediate portions of the alignment guide members 5 and 6 at the other end.
Since it is attached to a, 6a, the crank 7,
8 is converted into an eccentric movement in the width direction of the moving conveyor 1, as shown by the arrow in FIG.

However, since one end of the alignment guide members 5, 6 is rotatably supported on the machine frame 2 by the shafts 3, 4, as described above, the eccentric movement of the crank rods 9, 10 is caused by the eccentric movement of the alignment guide members 5, 6. ,6
The free end sides of the movable conveyor 1 are made to swing toward the center in the width direction of the moving conveyor 1 about the shafts 3 and 4, respectively. It is preferable that this swinging motion makes the distance between the alignment guide members 5 and 6 on the downstream side larger than the diameter of the transferred object 12 and smaller than twice the diameter.

Next, the operation of the above embodiment will be explained.

The plurality of rows of objects to be processed 12 that have been conveyed onto the transfer conveyor 1 through various processes are sent to the end by the belt movement of the endless belts 1a', 1a, 1a, . . . Then, it enters between the left and right alignment guide members 5 and 6.

At this time, the alignment guide members 5, 6 as described above
is swung in the width direction of the transfer conveyor 1 by the power transmission mechanism 11, so the objects 12 to be processed are gradually aligned in decimal rows, and the objects D that have reached the center are moved by the fast-moving endless belt 1a'. At the final exit, they are arranged in a single line and sent out to the passage 13.

Since the alignment guide members 5 and 6 are swung in a horizontal plane via the crank rods 8 and 9 by the rotation of the cranks 7 and 8, the object to be processed 12 may cause a bridging phenomenon between the alignment guide members 5 and 6. Moreover, if the bridging phenomenon occurs, it will work in the direction of destruction, and the force due to the swinging of the alignment guide members 5 and 6 will also be applied in the direction opposite to the direction of movement of the transfer conveyor 1, so that the flow will flow smoothly and in one row. and sent to the next process.

In the illustrated embodiment, the power transmission mechanism is composed of the crank 8 and the crank rod 10, but the alignment guide members 5 and 6 may be spring-biased and brought into contact with the eccentric cam. Furthermore, the configuration of each part is not limited to the illustrated embodiment.

As explained above, according to the present invention, a pair of left and right alignment guide members are provided near the end of a processing material transfer conveyor consisting of a plurality of belt rows so that the width becomes narrower toward the downstream side, and one of the alignment guide members is The alignment guide members are pivoted to the machine frame at the end on the upstream side so that they can swing freely in a horizontal plane, and the alignment guide members are alternately swung by a power transmission mechanism, so that The objects to be processed are shaken separately from the left and right sides on the upstream and downstream sides, and at the same time, the opening width at the end between the left and right alignment guide members is expanded or contracted, and together, the objects to be processed are shaken between the alignment guide members. It is reliably prevented from assembling the knots. In addition, a belt positioned at the center of the transfer conveyor is extended to a path connected to the central end of the transfer conveyor and conveys the objects to be processed in a single line, and this belt is connected to the other belts constituting the transfer conveyor. Since the conveyance speed is higher than that of a belt, the objects to be processed that reach the end between the alignment guide members are carried to the passage so as to pass through other objects to be processed, further preventing clogging at the outlet between the alignment guide members. This provides an excellent effect.
