Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is incorporated into the delivery side of a component supply device and individually checks the postures of the components to be delivered. The present invention relates to a component supply device determination device that supplies the assembly process.

[Prior Art] Since the parts are supplied from the parts supply device to the assembly process in the correct posture, the parts are mixed in the supply parts, for example, the reverse direction, the attitude inclined by 90 ° or 180 °, and the attitude defect. A posture determination device is used that automatically identifies objects and excludes them.

Then, in this discriminating device, it is necessary to accurately grasp the division of each component so that the posture can be surely checked for all the components. However, the components that are continuously supplied are often in close contact with each other, and the boundaries between them cannot be accurately grasped, which may cause malfunction. Therefore, it is necessary to sequentially separate the parts for discrimination.

The separating method of the parts used in the conventional discriminating device is (1) a method of blowing air to the supplied preceding parts for fast-forwarding, (2) a step on the part guide surface, or a downward direction. This is a method of providing a gap between the preceding part and the following part by providing a slope.

However, in the method (1), moisture in the air is
In some cases, oil or the like may be blown off to block the through hole of the light receiving portion in the posture determining means, or the lens of the light receiving portion may be soiled or clouded to make a correct determination. Also, in the method (2), the posture of the preceding component is lowered to the front,
An inverted triangle interval is formed between subsequent parts, which is used as an element to judge the quality of the posture of each part.
In some cases, triangular spaces did not occur and the paper was continuously fed, which was unreliable.

[Problems to be solved by the invention] In view of such a situation, the present invention is capable of reliably checking the attitudes of supply parts individually, and supplying only parts having the correct attitude to an assembly process with high reliability. It is an object of the present invention to provide a device component feeding posture determination device.

[Means for Solving the Problem] The present invention provides a sensing means for sensing the leading end of a preceding component of a component group that is continuously fed, and a feeding posture of the component in a component feeding posture determination device for a component feeding device. A posture determining unit including a determining unit for determining and a unit for eliminating a defective posture component, and a guide below the guide unit for guiding the supply component for separating the component from the subsequent component and performing preprocessing for sensing the leading edge of the subsequent component. And a fast feed roller having an outer surface partially projecting from the outer surface of the fast feed roller.

The above-mentioned feeding attitude determination means selects the number of determination elements and the installation position according to the shape of the component.

[Operation] The present invention facilitates sensing of the leading edge of the subsequent component by rapidly feeding the component to be sent to the next process by determining the posture, by a fast-forward roller, faster than the subsequent component.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, 1 is a component, 2, 2'is a light-emitting element and a light-receiving element as a leading edge tip sensing means, 3, 3'-
Reference numerals 5 and 5'denotes a light emitting element and a light receiving element as the feed position determining means (however, 4'and 5'are light receiving elements (not shown) located at positions facing the through holes 15 and 16), and 6 denotes an air cylinder and a piston. Means for eliminating defective components, 7 is a feed attitude determination unit, 8 is a guide, 9 is a fast-forward roller, 10 is a motor for fast-forward roller, 11 is a chute, 12 is a plate, 13
Reference numerals 16 to 16 are through holes for the light receiving element.

FIG. 2 is a view of the discrimination device of the present invention seen from the chute side of FIG. However, it is partially omitted in FIG. Reference numeral 20 is a pointing plate that supports the light projecting section 22, 21 is a cover, and 23 is a light receiving section.

FIG. 3 illustrates a mechanism for separating the preceding part 1 from the succeeding part 1'by a distance m, and the fast-forwarding roller 9 can surely make a distance m from the succeeding part. Then, if there is a component with a bad posture, the piston of the posture-defective component removing means 6 operates to remove it.

In such a device, the leading end portion of the preceding component 1 of the component group continuously sent out from the component supply device has the feeding posture determination unit 7
When it is sensed by the tip sensing means 2, 2 ', the shape discriminating circuit catches the signals from the light projecting portion and the light receiving portion as shown in the block diagram of FIG. The signals obtained from 3,3 'to 5,5' (shown collectively as the light emitting unit and light receiving unit in Fig. 4) match the ON-OFF signal of the normal posture preset by the shape of the parts. It is confirmed by the control unit whether or not to do so, and in the case of a bad posture, a signal is sent to the excluding unit in FIG. 4 to operate the excluding means 6 to exclude the part from the line, and when the parts are in agreement, the part is passed as it is. Then, it is separated from the following parts by the fast-forward roller 9 and fed into the chute 11.

In this way, the succeeding parts can also be individually and reliably discriminated in the feeding attitude.

For example, in the case of a part having the shape shown in FIG. 6, if the tip 60 of the part is in a normal feed position (ON) when the sensing means 2, 2'detects it, the posture determination means 3, 3'-5, 5 '. Since ′ is located in the notch 61 and the holes 62 and 63, these are all OFF (FIG. 5A). Therefore, if the posture determination means 3, 3'-
If either of 5 and 5'is ON, it means that the parts have not been sent in the correct posture. At this time, a defective product elimination signal is output (FIG. 5B) and the elimination means 6 is activated.

[Advantages of the Invention] According to the configuration of the present invention, with respect to the components continuously supplied from the component supply device, the outer surface is partly below the guide that guides the interval between the preceding component and the subsequent component. Since it can be reliably opened by the protruding fast-forward roller, the feeding posture of each component can be checked reliably for each individual component.Because air blowing is not used, it depends on the usage environment. It is possible to improve the reliability of posture determination without causing a judgment error such as when air is used even when used for a long time.
