Abstract

PURPOSE:To correct the orientation of an object to be transported without disturbing the following stage by constituting a transport unit with two conveyers which are placed in series and linked with each other, and by placing an entrance roller of the trailing conveyer a little higher than an exit roller of the leading conveyer. CONSTITUTION:The unit consists of two conveyers which are placed in series and linked with each other, and an entrance roller 3' of a trailing conveyer 2 is placed a little higher than an exit roller 4 of a leading conveyer 1. In other words, when a slender board 6 is transported on a conveyer 1, one end A of the board 6 which has arrived earlier at the conveyer 2 cannot be transferred onto the conveyer 2, with the friction force of one or two ropes 5 due to a step between the two conveyers. It can be transferred on the conveyer 2 only after the late-arriving end B reaches the conveyer 2 and the front edge of the board 6 is adjusted to be parallel with a roller 3'. Accordingly, the transport direction of the board 6 is adjusted in advance so that no trouble occurs in the following stage, in which, for example, the board is automatically stored in a cassette.

顕著に現われる。On the other hand, since the conveyor is incorporated into production equipment and performs various processing and processing on the conveyed objects on the conveyor, it is also necessary to change the conveyance speed of the conveyed objects during the conveyance of the conveyed objects in a specific process section. In this case, especially if one of the multiple conveyors is moved quickly, the conveyed object may tilt at the transition section where it transfers to the faster conveyor, or one side of the conveyed object may transfer first and the direction may change by nearly 90 degrees. It rotates and becomes unstable. For example, when the object to be transported is a long and thin substrate, ceramic or glass substrates (hereinafter simply referred to as substrates) used for thermal heads in particular tend to be longer in length and narrower in width. It has become. This is to save material costs and make the product more compact. When processing such a substrate with chemicals, it is desirable to transport the substrate with the narrower side in the transport direction in order to make the length of the processing chamber as short as possible. For this reason, stable conveyance at the transition portion of the conveyor becomes even more difficult, and if the object to be conveyed is transferred to the subsequent stroke while the direction of the conveyed object remains rotated, various problems will occur there. This is especially noticeable in automated equipment.

一方、被搬送物の向きを修正するため，搬送径路の途中
で被搬送物か当接する部材を介在させたものは公知であ
るが、この場合被搬送物に何らかの機械的衝撃が加わる
とともに、搬送径路が長く複雑化する欠点がある。On the other hand, in order to correct the direction of the transported object, it is known to interpose a member that comes into contact with the transported object in the middle of the transport path, but in this case, some mechanical shock is applied to the transported object and the transport The disadvantage is that the route is long and complicated.

そこで本発明は、上記の不都合を解消する新規な装置を
提供するため案出されたもので、以下その実施例を添付
図面により説明する。Therefore, the present invention has been devised to provide a new device that eliminates the above-mentioned disadvantages, and embodiments thereof will be described below with reference to the accompanying drawings.

式コンベアになっている（第２図参照）。What is shown in FIG. 1 is a conventional conveyor, which consists of a front-stage conveyor 1 and a rear-stage conveyor 2, and both conveyors 1 and 2 are arranged on the same horizontal plane. The conveyor 2 at the rear stage has a faster conveyance speed than the conveyor 1 at the front stage, and these conveyors 1.2 have entrance and exit rollers 3, 4, .
It is a rope-type conveyor in which a plurality of ropes 5 are stretched between 3' and 4' (see Fig. 2).

隔がつまり基板が追突することになる。Therefore, the elongated substrate 6 that has been sent on the conveyor 1 at the front stage in the direction of the arrow is usually affected by the external force for chemical treatment (for example, the jetting force of the chemical) in the pre-processing process as shown in FIG. , this also occurs when the direction of the conveyor rotates. 0 If the transfer is made to the subsequent conveyor 2, which has a higher speed, in this state, the point A side, which arrived at the subsequent conveyor 2I first at the transition section 7, will move faster to the subsequent conveyor. 2, and since the point B side is still on the conveyor 1 in the previous stage, it will be transferred to the conveyor 2 in the latter stage while rotating more and more counterclockwise (in the Y direction). In this case, in the 9th example, the gap between the boards becomes clogged in the subsequent process, resulting in a rear-end collision between the boards.

不都合は生じない。Therefore, in the present invention, as shown in FIG. 3 (in this figure, the same parts or equivalent parts as in FIG. In this way, even if the side corresponding to point A in FIG. However, the friction force of one or two of the ropes 5 does not allow the rope to transfer to the subsequent conveyor 2, and the side corresponding to point B in FIG. 31 and the front side of the substrate 6 are aligned until they are parallel to each other, and then the substrate 6 is transferred to the subsequent conveyor 2. Therefore, the orientation of the substrate 6 in the conveying direction is corrected.
In the post-process, for example, when automatically stored in a cassette, no inconvenience occurs.

This is especially effective in the case of

被搬送物の向き修正装置であって、次の効果を奏する。In summary, the present invention is a device for correcting the orientation of a conveyed object at a transition section, which is composed of two conveyors connected in series, and in which the entrance roller of the subsequent conveyor is arranged slightly higher than the exit roller of the preceding conveyor. , has the following effects.

部で容易に修正することができる。■Since there is no special intervening member to adjust and correct the conveyance direction, and the conveyor is simply brought into contact with the conveyor at the subsequent stage, the shock caused by the contact of the conveyed object is alleviated, and it does not complicate the mechanism in any way. ■Note that when the object to be conveyed is a thin piece, for example a board, the orientation of the conveyed object is already uneven on the previous stage conveyor due to warping of the thin piece itself, but this unevenness is corrected by the crossing section. can be easily corrected.
