Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveyor row convergence device that reduces the number of conveyor rows by transferring objects between a plurality of parallel conveyors.

Convergence of conveyor rows is often required when there are processing machines with different processing capacities in a transport processing line for conveyed objects.

For example, in a bottling machine with low processing capacity, the number of conveyor lines is increased, and in a boxing line for packaging the bottles, the number of conveyor lines is reduced to match the high capacity.

The present invention proposes a device that can easily converge such conveyor rows, and transfers objects on one conveyor onto another conveyor using a transfer rod provided on the side of the conveyor. It is characterized in that a timing device is used to provide an appropriate distance between the objects to be conveyed on the conveyor in advance so that there is no interference between the objects to be conveyed during this transfer.

The present invention will be described below with reference to the illustrated embodiment. In this embodiment, a conveyor line of three rows A, B, and C is used.

This case deals with the case where the number of rows B2 is reduced by 1, that is, the case where containers 1 on conveyor C are distributed and transferred onto conveyors A and B.

Conveyors A, B, and C are separated from each other in the stage before forming the row number changing section 2 in which they are closely spaced in parallel. Screws 3A, 3B, and 3C are provided.

These timing screws rotate in synchronization with each other, and adjust the container spacing and position so that container 1 on conveyor C is positioned between containers 1 on conveyors A and B, as shown in the figure.

On the side of the conveyor row number changing section 2, transfer rods 4A, 4B arranged alternately and a drive mechanism thereof are provided.

The transfer rods 4A and 4B are fitted into a cylinder 11 attached to a rotated endless body 7, which is hooked between the front and rear sprockets 5 and 6 in the direction of movement of the conveyor, thereby moving forward and backward in a direction perpendicular to the conveyor. Enabled and supported.

(See FIG. 2). Also, the transfer rods 4A, 4B are provided with a push-out piece 8 at the end on the conveyor side, and cam followers 9A, 9B at the end on the opposite side, respectively.

The outer side of the endless body 7 is provided with fixed cams IOA and 10B, which the cam followers 9A and 9B engage with, and therefore the transfer rods 4A and 4B are connected to these cams 10A and IOA.
Work and retire according to the OB.

The lift of cam l0A10B is shown in Figure 1i,
The cam 10A moves the transfer rod 4A back and forth to move the extrusion piece 8 from the conveyor C onto the conveyor A.

Similarly, the cam 10B moves the push-out piece 8 of the transfer rod 4B from the conveyor C onto the conveyor B.

As is clear from FIG. 2, the cam follower 9A is set higher than the cam follower 9B.
It is possible to overcome the branching part of 10B and give a large lift amount to the transfer rod 4AIC.

Therefore, this apparatus with the above configuration is conveyor A.

By moving B and C at the same speed and rotating the endless body 7 synchronously with them, containers can be transferred as shown.

That is, when the container 1 on the conveyor C and the transfer rods 4A and 4B supporting the endless body 71 are driven so that their positions match, the transfer rods 4A and 4A on the conveyor C move as the endless body 7 moves I. Push every other container 1 onto conveyor A,
The transfer rod 4B similarly pushes the remaining containers 1 on the conveyor C onto the conveyor B.

Conveyor A as mentioned above. The intervals and positions of the containers 1 on B and the containers 1 on conveyor C are set by timing screws so that their positions in the conveying direction are different.
Therefore, there is no possibility of interference occurring between the containers 1 during the transfer.

In the above embodiment, transfer rods 4A and 4 for conveyors A and B are used.
Two cams 10A to move B forward and back.

10B is used, but if the transfer rods 4A and 4B are fixed as a pair as shown in FIG. 3 and a cam follower 9 is attached to this, the same operation as above can be obtained with a single cam 10. .

The conveyor row convergence device of the present invention can be similarly applied to conveyors with different numbers of rows based on the same technical idea as described above.

Figure 4 shows an example of this, with four rows of conveyors A and B.
, C, and D, the containers 1 on two rows C and D are moved to rows A and B by f as indicated by the arrows, so that there are two conveyor rows.

In this case, of course, a timing device is used to appropriately set the interval between the containers 1 as shown in the figure.

Although the present invention has been described above with respect to a device for reducing the number of conveyor rows, it is possible to reverse the movement directions of the conveyor and the transfer rod, and to use the pressing piece 8 of the transfer rod as a suction cup, or to use the transfer rod as a suction cup. It is clear that if the installation position is on the opposite side of the conveyor, it can be used as a device for increasing the number of conveyor rows.

As described above, according to the present invention, there is a mutual interaction between a timing device that sets the interval and position between objects to be conveyed on a conveyor, and a transfer rod that transfers objects to be conveyed from one conveyor to another. As a result, the objects on the plurality of conveyors can be moved smoothly without interfering with each other, and the number of conveyor rows can be converged.

Particularly, in the present invention, an endless belt provided with a plurality of transfer rods is provided on one side of three or more conveyor rows, and the upstream side of the conveyor row is placed on the conveyor adjacent to the endless belt. A timing device is installed to provide a predetermined interval between the conveyed objects on each conveyor so that the conveyed objects are at an intermediate position between the conveyed objects on the other conveyors. The endless belt is provided with a lift amount applying means that alternately applies at least two different transfer lift amounts reaching from the conveyor adjacent to the endless belt to the conveyor on the far side respectively. Therefore, even if the number of conveyor rows increases, the above-mentioned timing device can ensure accurate relative positions of the containers between the rows.Moreover, the simple lift amount applying means with alternating lift amounts provided only on one side of the double-row conveyor There is an advantage that a desired reduction in the number of rows can be easily achieved and good focusing efficiency can be achieved.
