Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an object transfer device for sequentially transferring glass containers, paper containers, and other objects.

Conventionally, in this type of object transfer device, a belt for sequentially transferring glass containers, paper containers, and other objects that have been processed at a preceding station to a following slider is cut between the preceding station and the following station. In this case, objects are sequentially transferred from the leading belt conveyor to the trailing belt conveyor via a crossing system using star-shaped wheels. However, if the object transfer speed of the preceding belt conveyor increases, there is a possibility that the crossing using the star-shaped wheel may not be able to transfer the object properly if only horizontally.

The present invention seeks to provide an object transfer device that eliminates the above-mentioned drawbacks.

The details will be explained below along with the drawings.

When the object SOT is locked between the guide member GD+ and the guide member GD+, one side Lv1 of the detection means DET is pressed by the locked object BOT, and one side LV+ of the detection means DET is pressed.
and the other surface LVλ is rotated counterclockwise about the pivot shaft PVSHFT.

When the other surface +Vλ of the detection means DET is rotated counterclockwise in the g1 direction, the microswitch M S /fi A is turned off and the drive source of the trailing belt conveyor BLTλ is turned off.

As a result, the preceding belt conveyor [31Tl is also stopped. If the captured object BOT is removed by the bribe observer, the force of pressing L from one side LV1 of the detection means DET is removed, so J is applied to the spring SP, and the detection means DE
One side Lv, tj and the other side 1-V2 of T are rotated clockwise around the pivot shaft PVS'HFT and returned to the initial position. Along with this return operation, the micro switch MS is turned on and the trailing belt conveyor BLT is turned on.
Yu's drive source is turned on. As a result, the preceding belt conveyor BLT+ is also restarted.

In the above description, three main stars 7i are attached to the main star axle, but the number may be reduced or increased as desired. Similarly, the leading star axle and the trailing star axle are each equipped with two leading stars ff1Jj and two trailing stars, but the numbers may be reduced or increased as desired.

It will also be clear that any suitable belt means, such as a belt-like belt, may be used in place of the round belt. The belt means may be stretched between at least the leading star Φ shaft and the trailing star axle.

In addition, the main star-shaped tonne shaft, leading star-shaped axle, and trailing star-shaped axle supply screw body are connected to the rotating shaft of the driven wheel of the trailing belt conveyor via a gear train, but depending on the situation, the trailing belt conveyor may be It may be driven by another power source. Similarly, the rotating shaft of the driving wheel of the leading belt conveyor is connected to the rotating shaft of the driven wheel of the trailing belt conveyor via a gear train, but this is also driven by a power source separate from that of the trailing belt conveyor, if desired. You may.

Further, the number of recesses in the main star wheel is 15, and the number of recesses in the leading star wheel and the number of recesses in the single star wheel are 6, but these numbers may be adjusted as appropriate if desired. good. In other words, as long as the spacing between the recesses on the main star wheel, the spacing between the recesses on the 0-row star wheel, and the spacing between the recesses on the trailing star wheel match during operation, the number of recesses may be selected appropriately. .

As is clear from the above, the object transfer device of the present invention has a transfer mechanism disposed between the leading belt conveyor that transports the object from the leading station and the trailing belt conveyor that transports the object to the trailing station. Set the direction of extension of the leading belt conveyor to the direction of extension of the trailing belt conveyor.
Can be crossed. In the present invention, $J'I
Since Q'a +ii takes the object outward from the extending direction of the first 11 belt conveyor and then supplies it to the trailing belt conveyor, it is possible to expand the transfer distance down to the passing mechanism. It is particularly advantageous that additional processing of the object, such as labeling, etc., can be carried out, and abnormality inspection, such as damage inspection, of the object can also be carried out.

Furthermore, in the object transfer device J3 of the present invention, since the object supply screw body is arranged at the entrance of the crossing structure, even if the object transfer speed by the preceding belt conveyor increases, the objects are sequentially transferred to the preceding star car and Can be reliably supplied to the main star car. In addition, since a detection means is arranged at the inlet of the supply screw body, it is possible to quickly respond if the object is not being properly supplied to the supply screw body.

Incidentally, since the supply screw body and the guide members facing the supply screw body via the preceding belt conveyor need only be disposed on both sides of the preceding belt conveyor, the bottom of the groove may be opposite to that described above.

Furthermore, although a detection means is used in the above description, it may be removed or other detection means may be used if desired.
