Description

[Detailed explanation of the idea] The present invention relates to a device for standing up flat plate-shaped articles.

In the manufacturing process of flat plate-shaped articles such as heat insulators and poultices, these plate-shaped articles are sent out from the manufacturing process in an overturned state and sent to the next inspection process.

By the way, when inspecting these articles for good or bad in the inspection process, it is preferable to stand the article up because both sides can be inspected at the same time and the article does not get dirty or scratched. I make them stand up before sending them to the inspection process.

A conventional device for raising up a plate-shaped article during transportation has generally had a structure as shown in FIG.

This device attaches a plurality of conveyance jigs at predetermined intervals to an endless belt or chain a that moves around, and transfers a flat plate-shaped article M in a fallen state onto the conveyance jigs. A groove d having a width capable of accommodating the article M is provided near the position where the moving direction of the tool changes, that is, the position of the pulley or sprocket for the belt or chain, and allows the article M to slide and stand up with an arcuate guide C. It is supplied to the standing jig e in an upright state.

However, in this case, there is a problem in that a feeding error occurs because the time from when the article M begins to slide on the guide C until it is fed onto the upright jig e is not constant.

In order to eliminate such a problem, a shutter mechanism f is provided to temporarily stop the article M in the middle of the guide, and the article is temporarily stopped by this shutter mechanism, during which the standing jig e comes to the position below the guide C. In this case, a new shutter mechanism must be installed, and the operation of the shutter mechanism must be linked to the operation of the belt or chain and the operation of the standing jig. Therefore, there is a drawback that the device becomes complicated and the cost becomes high.

The present invention was developed in view of the above-mentioned problems with the upright device, and its purpose is to provide an inexpensive upright system that can reliably supply the upright state without any supply errors and without providing a shutter mechanism. The goal is to provide equipment.

In the present invention, a plate-shaped article to be erected is placed on a conveyance jig that is continuously conveyed at a fixed interval and conveyed, and a guide is provided adjacent to a curved movement path of the conveyance jig to guide the conveyance jig. In a standing device for dropping and standing up a plate-shaped article along a path, a stopper capable of protruding from the surface of the guide is provided at the rear of the conveyance jig, and the guide has a radius of curvature larger than the radius of curvature of the curved movement path. and the curved movement path has a curved shape with its center of curvature at a position different from the center of curvature, and the stopper stops the conveying jig in the middle of the guide before the plate-shaped article falling along the guide becomes upright. An article that is capable of sinking from the surface of the guide as it moves, and that is transported by a conveyance jig having a trailing stopper before the preceding stopper sinks from the surface, and the distance between adjacent stoppers in the front-rear direction is adjusted. is configured so that it begins to slide along the guide.

Embodiments of the erection device according to the present invention will be described below with reference to the drawings.

In FIG. 2, an upright device 1 according to this embodiment is shown.

In the figure, 2 is an endless chain that is stretched between a pair of sprockets 3 (only one is shown) and is rotated in the direction of the arrow X; 4 is a conveying jig that is attached to the chain 2 at a certain distance; Reference numeral 5 indicates a guide provided close to the sprocket 3, and reference numeral 6 indicates an upright jig for receiving the article M that is moved along a certain path and dropped and stood up along the guide 5 when passing the lower end of the guide. It is a ingredient.

The conveying jig 4 includes a horizontal portion 41 on which a flat plate-shaped article is placed, and a stopper 42 protruding in a direction substantially perpendicular to the horizontal portion 41 at the rear of the portion 41 (as viewed from the moving direction of the conveying jig). From the L-shaped main body 40 consisting of
As shown in FIG. 4, the main bodies are fixed in pairs with a chain 2 sandwiched between them.

The guide 5 is cut out from a substantially arc-shaped plate 50, and the plate is provided with a pair of grooves 51 through which the stopper 42 of the above-mentioned conveying jig can pass, as shown in FIG.

The center of curvature O' of the surface 52 of the guide 5 and the rotation center of the sprocket, and therefore the rotation center O of the conveying jig 4, are such that while the conveying jig is pivoting about the rotation center O, the stopper 42 is In the middle, for example, at position A1, it is shifted in advance from the surface 42 so as to sink into the groove 51.

Also, the distance between adjacent transport jigs, and therefore the distance between the stoppers 42, is such that the distance between the preceding transport jigs 4.4a and the stoppers 42 is such that the following transport jig 4. The article M conveyed by the jig 4.4b begins to fall along the surface of the guide 5, and the tip Mf of the article comes into contact with the rear surface 43 of the preceding guide 42, causing the article M to temporarily stop falling (position A) is predetermined by taking into account the radius of curvature of the guide surface, the radius of the sprocket, and the sliding friction between the article and the guide.

In the upright device configured as described above, as the chain 2 moves in the direction of the arrow ), the article M begins to slide along the guide 5, and when it reaches the position C, the article M comes into contact with the rear surface 43 of the stopper 42 of the preceding conveyance jig 4, 4a that has reached the position, and the article M starts to slide along the guide 5. Falling is regulated.

Thereafter, until the tip of the stopper moves to position A, that is, until the tip sinks from the surface of the guide, the article
moves at the same speed as the moving speed of the tip of the stopper, and after the tip of the stopper sinks from the surface of the guide, it falls freely along the surface, and is placed and held in an upright state on the standing jig 6, The erecting jig sends it to the next process, for example, an inspection process.

Thereafter, the articles are successively erected in the same manner.

As is clear from the above explanation, in the standing device according to the present invention, a stopper is provided on the conveying jig, and the stopper temporarily restricts the falling of the articles, so that there is no unevenness in the falling of the articles over time. There is no need to provide a shutter mechanism with a complicated structure, and the cost of the device can be reduced.

Moreover, it is possible to reliably stand up the articles and supply them.
