Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in an automatic alignment device for a multi-row conveyor installed in, for example, a temperature bath for aging semiconductors.

[Prior Art] A multi-row conveyor is usually installed inside a temperature chamber for aging semiconductors, a paint dryer for mechanical parts, etc. to convey a large number of products and process them all at once under the same conditions. ing.

Generally, multi-row conveyors installed in this type of apparatus are provided in parallel in the middle of the product flow path. Then, the objects sent from the previous process through the single-row input conveyor are fed into the multi-row conveyor, and the transferred objects are again discharged onto the single-row discharge conveyor and sent to the next process. configuration is adopted. In this case, the objects to be conveyed, which have been placed on the input conveyor in the order of production, may become confused during conveyance and be discharged onto the discharge conveyor in an out-of-order order.

[Problems to be solved by the invention] Conventionally, in order to make the conveyance order the same at the time of input and discharge,
A method has been used in which a label indicating the order of the transported items is affixed to the transported items, and after the items are discharged, the labels are used to arrange the transported items in the same order as when they were input. However, in such a system, there is a problem that not only is it troublesome and man-hour-consuming to attach labels to and align the individual conveyance items, but also that there is a lot of manual work and automatic operation is no longer possible.

The present invention has been made to solve the problems of such conventional methods.

[Means for Solving the Problem] The inlet port of the transfer input section and the outlet port of the transfer discharge section, which are provided intersectingly before and after the multi-row section and are driven in the same direction, are connected to the multi-row section. In contrast, a multi-row conveyor was constructed which was arranged diagonally opposite to each other.

[Operation] The objects sent from the front row to the opposite row at the inlet of the multi-row section are transferred to each row of the multi-row section in the same order by the transfer input section. The objects transferred to the multi-row section form negative rows and are transported to the discharge side. Then, the conveyed objects that have been transported to the discharge side are transferred to the transfer and discharge section, and are sequentially discharged from the opposite row side at the take-out port.

[Embodiment of the Invention] Fig. 1 is an explanatory diagram of the configuration of an embodiment of the present invention, in which (a) is a plan view, (b) is a front view, and Fig. 2 is an explanatory diagram of its operation. The present invention will be explained by exemplifying a temperature bath for aging.

In FIGS. 1 and 2, (1) is the main body of the temperature chamber. (2) and (3) are an input section and an output section provided before and after the main body (1). Both the input section (2) and the discharge section (3) are composed of a single row of conveyors, and are provided in the direction along the flow of the product as indicated by the hollow arrow (A).

facing the start and end of all rows along the input and discharge sides. The transfer input section (5) and the transfer discharge section (6) are connected to each other in the number of rows near the center of each row of the multi-row section (4) using a means such as a conveyance platform. Same as 9
conveyed items are placed. (51) is the transfer input section (5)
The inlet port (61) is the outlet port of the transfer/discharge section (6). Inlet port (51) and outlet port (6

(Sl), (S2), . . . are semiconductors transported along the flow path.

The present invention will be described in detail below with reference to FIG.

The completed semiconductors (Sl), (S2)... are the input part (2
) toward the temperature chamber (1) as shown by the arrow, for example, in the order of production. The semiconductors (Sl), (S2), etc. sent into the temperature chamber (1) are transferred to the transfer input section (
The feeding direction is changed to a right angle at the feeding port (51) of 5), and the pieces are fed in order from the 9th row side to the 1st row side. And the semiconductor (Sl) sent here, (
S2) waits for transfer until the number of... reaches the number of rows in the multi-row section (4). Semiconductors (SL), (S2), etc. sent to the transfer input section (5) are head-loaded from the destination and are transferred to 9.
Once filled, the semiconductors (Sl) to (S9) are sequentially transferred from the first row side to the multi-row section (4) side. When such a transfer/insertion operation is completed for a group of semiconductors (Sl) to (S9) from the first to the ninth rows, all the rows of the multi-row section (4) will move at the same time as indicated by the arrow (A). As well as starting to move in the direction,
The preceding semiconductor group (S
1) to (S9) are transferred to the transfer/discharge section (6). The semiconductors (Sl) to (S9) transferred to the transfer/discharge section (6) are sent toward the perpendicular direction CB), and are sent to the takeout port (61).
In the process, the liquids are sequentially discharged to the discharge section (3) from the first row side.

Thereafter, the semiconductor (Sl) discharged to the discharge section (3)
S9) are arranged in the original manufacturing order and transported to the next process. FIG. 2 is a timing chart showing the above-mentioned operation, and in each section from time (tl) to (t3),
Each operation described in and ■ is performed.

In this way, the semiconductor groups (Sl) to (S9) arranged in exactly the same order as when the temperature bath (1) was loaded are transferred to the discharge section (

and is connected in parallel to the transfer and discharge section (6). According to the apparatus of this embodiment, there is no change in the conveyance direction at the two connection points, so that the article can be conveyed smoothly.

Although the above-mentioned embodiment has been explained by exemplifying a multi-row conveyor in a temperature chamber for aging semiconductors, the apparatus of the present invention can also be applied to the above-mentioned paint dryer and other apparatuses. Furthermore, although the 9th row side of the multi-row section is used to input the input to the transfer input section, and the transfer and discharge section is discharged from the 1st row side, the reverse is also possible. It's fine as long as it's a coincidental relationship.

[Effects of the Invention] As explained above, according to the present invention, a transfer input section and a transfer discharge section are provided on the input side and the discharge side of the multi-row section for transferring the transferred articles one after another. In addition, a multi-row conveyor is constructed in which the inlet of the transfer input section and the takeout port of the transfer and discharge section are arranged in a diagonal relationship with each other. As a result, in the discharge section, it is possible to discharge and convey the conveyed objects that are automatically arranged in the same order as when they were input.

Therefore, according to the present invention, it is possible to provide an automatic alignment device for a multi-row conveyor, which has a simple configuration and is capable of discharging the conveyed objects in the same order as when they were input.
