Description

[Detailed description of the invention] The present invention detects the surface with protruding burrs and other surfaces of plate-shaped pressed products, etc., and selects and transfers only the pressed products with protruding burrs on the upper surface. Regarding a transfer device.

In general, press products made by punching out plate materials have protruding burrs on one side, and therefore require a deburring process using a grinder or the like as post-processing.

For this reason, it is necessary to detect which side of the pressed product's protruding surface is so that the bead always hits the grinder, but conventionally this work has been done manually, which is a tedious process. was there.

The present invention was developed in view of the above circumstances, and its purpose is to automatically sort objects to be sorted, such as pressed products, and to transport only those objects that have a predetermined surface as the surface. The present invention provides a sorting transfer device.

The present invention will be explained below based on an example in which the present invention was applied to a deburring process.

FIG. 1 is an overall schematic diagram in which a conveyor 1, a conveyor 2, and a sorting mechanism 3 are arranged in this order, and the objects 4 to be sorted, such as pressed products sent from the sorting mechanism 3, are deburred by a deburring device. It is deburred in step 5.

The conveyor 1 has a rectangular shape and is inclined downward toward the conveyor 2, and has a metal steel 6 provided on its surface.

Further, a tension coil spring 7 is attached to the upper part of this carrier 1, and a vibration motor 8 is attached to the lower part.By driving this motor 8, the gold@6 is vibrated upward, and the gold@6 is The objects 4 to be sorted are sequentially moved in the direction of arrow A.

Further, the conveyor 2 is inclined upward, and a plurality of projecting pieces 9 are provided on the conveyor 2.

Each projecting piece 9 is provided in a direction perpendicular to the traveling direction of the conveyor 2 with a gap equal to or larger than the width of the objects 4 to be sorted, and the objects 4 to be sorted are placed here and moved upward. .

A pair of separating guide plates 10, 11 are provided on the conveyor 2, as shown in FIG.

Each separation guide plate 10.11 is adjustable and spaced apart from the conveyor 2 by an interval longer than the thickness of the objects 4 to be sorted and shorter than twice the thickness, so that one object 4 to be sorted can pass through. However, of the two stacked objects to be sorted, the upper object to be sorted 4 is not allowed to pass through.

Furthermore, one separation guide plate 10 is bent into a dogleg shape and is located below the conveyor 2.

The other separation guide plate 11 is bent into an inverted dogleg shape and is located above the conveyor 2.

These separation guide plates 10.11 form inclined guide walls 10a, lla in the center of the conveyor 2, and the gap between these guide walls 10a, lla can be adjusted to be equal to or larger than the width of the objects 4 to be sorted. The object to be sorted 4 can pass through this.

Further, the top of the conveyor 2 is covered with a hat-shaped body 12,
Conveyor 2? This prevents the objects 4 to be sorted that have reached the section from coming off the protrusion 9 and falling.

Next, the sorting mechanism 3 consists of a burr detection body 13, a transfer plate 14 for the objects 4 to be sorted, and a reversing plate 15 for the objects 4 to be sorted.

The burr detection body 13 detects whether the uneven surface of the objects 4 to be sorted is on the front side or the back side, and is provided so as to be inclined downward from the top of the conveyor 2.

As shown in FIG. 3, the streamer detection body 13 has a large number of protrusions 16 formed on its surface, for example, a plurality of rows of saw teeth are arranged in parallel.

In this case, the upper teeth of each protrusion 16 are inclined horizontally or downwardly, so that even if a dovetail is formed on the back surface of the object 4, the dovetail cannot be locked on the protrusion 16. First, the objects 4 to be sorted are prevented from sliding and stopping.

The inclination angle of the deflation detection body 13 can be adjusted as appropriate, and although this inclination angle varies depending on the type of the object to be sorted 4, it is usually preferably 30 to 40 degrees.

Further, an arcuate guide plate 17 is attached to the lower end of the curvature detector 13, and the reversing plate 15 is provided below the guide plate 17.

The reversing plate 15 is curved in a substantially S-shape and inclined downward, and its lower end is positioned above the carrier 1.

Therefore, the objects 4 to be sorted that have fallen from the burr detection body 13 onto the reversing plate 15 are sent onto the conveyor 1 again with their front and back surfaces reversed.

Furthermore, a transfer plate 14 is provided below the extension line of the above-mentioned upstream detection body 13 through an opening 18 formed by a guide plate 17 and a reversing plate 15.

This transfer plate 14 transports the objects to be sorted 4 to the deburring device 5, and is capable of adjusting the length of the opening 18 by moving in the longitudinal direction.

Further, the deburring device 5 has a plurality of belt grinders 20 arranged on a belt conveyor 19.

Next, the operation of the sorting and transferring device having the above structure will be explained.

First, a large number of objects 4 to be sorted, which have been pressed and shaped using a press device (not shown), are placed on the conveyor 1.

In many cases, the objects 4 to be sorted are covered with oil and have two or more sheets stacked on top of each other, and burrs are protruding from one side.

When the objects 4 to be sorted in such a state are placed on the carrier 1, they are moved in the direction of arrow A while being separated from each other by the vibration effect.

Also, oil is removed from the gold steel 6 during movement.

When the objects 4 to be sorted are thus separated and reach the left end, they are caught on the protrusion 9 of the conveyor 2 and ascend in the direction of arrow B.

In this case, if the objects 4 to be sorted overlap, the object 4 to be sorted below
rises without hitting the separation guide plate 10.11, but
The objects to be sorted 4 stacked on top hit the separation guide plate 10,
These objects 4 to be sorted are separated one by one.

The upper object to be sorted 4 separated in this way is moved to the guide wall 10
It ascends diagonally while being guided by a and lla.

If there is a place on the projecting piece 9 of the conveyor 2 where there is no object 4 to be sorted, the object 4 moving along the guide walls 10a, lla will fall onto the conveyor 2, and the object 4 will fall onto the conveyor 2 and the separating guide plate. 11 and rises in the direction of arrow B.

In this way, the objects 4 to be sorted are separated one by one by the separation guide plates 10 and 11, but when they reach the top of the conveyor 2, they slide over the projections 16 of the burr detection body 13. .

If burrs protrude from the surface of the object 4 to be sorted and the back surface is smooth, the frictional resistance with the projections 16 is small and the object slides down at a relatively high speed.

Therefore, the objects 4 to be sorted fall onto the transfer plate 14 without falling into the opening 18 and are transferred onto the belt conveyor 19 of the deburring device 5, and the belt conveyor 19 removes the debris on the surface of the objects 4 to be sorted. Ru.

On the other hand, although the surface of the object to be sorted 4 has a protruding burr and is smooth, the burrs of the object to be sorted 4 fall while hitting the protrusions 16, so the sliding speed is slow.

Therefore, the object to be sorted 4 is moved along the guide plate 17 to the opening 1.
8, passes through the reversing plate 15, and falls onto the gold copper 6 of the carrier 1.

When moving on the reversing plate 15, the beveled surface of the object 4 to be sorted is reversed from the back surface to the front surface.

Therefore, when the object 4 to be sorted moves up the conveyor 2 from the conveyor 1 and slides down on the burr detection body 13, the surface with the protruding emboss becomes the surface, and in this state, it is transferred to the deburring device 5. .

In this way, the sorting mechanism 3 detects whether the surface of the object to be sorted 4 on which burrs are protruding is on the front side or the back side, and sends only the case where the burrs are on the front side to the deburring device 5. , it is automatically reversed and sent to the deburring device 5.

Therefore, separation and sorting of the objects 4 to be sorted in the deburring process can be performed automatically and reliably without any manual effort.

The sorting and transfer device according to the present invention is not limited to a device that detects flaws and brings the protruding surface to the surface, but also a device that automatically sorts objects when the smoothness of both sides of the object is different. It can also be used as

Further, the sensing body according to the present invention is not limited to a sawtooth structure, and may have other structures having similar effects.

As explained above, according to the present invention, the surface properties of the objects to be sorted are detected by utilizing the difference in the speed at which the objects to be sorted slide down on the detection object, and only those with the desired surface are selected automatically. It can be transferred accurately and reliably, and is particularly suitable when applied to the process of removing a protrusion on one side of a pressed product.
