Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an automatic sequential conveyance device for laminates.
More specifically, for example, intermediate products of resin-sealed electronic components, such as resin-sealed semiconductors, which are supplied in a layered state to the point where they need to be transported, are automatically conveyed one by one to the completion process. Furthermore, the present invention relates to a device used to automatically transport products processed in the completion process one by one to a required location.

As shown in FIGS. 5 to 7, the conventional automatic sequential conveyance device for seed laminates is equipped with a shaft mounted on a guide bar, arranged so as to be able to reciprocate in the horizontal direction through a cylinder opening, and with a required number extending forward at the top. A main body 2 of the conveying device has a first delivery arm of a length extending therefrom, and a main body 2 of the main body is pivotably connected to the first delivery arm in parallel with the first delivery arm at the rear side above the proximal end of the main body. A second feeding part that is longer than the first feeding bar and has a plurality of feeding claws protruding from the lower surface at predetermined equal intervals, and a first feeding berm and a conveyance platform in front of it. A supply mechanism for the laminate having a pedestal arranged so as to be able to be raised and lowered by a cylinder (not shown) therebetween, and a laminate supply mechanism 12 which has a pedestal disposed in between so as to be movable up and down by a cylinder (not shown); A first stopper is disposed in front of the proximal end to collide with the rear side to rotate and lower the part to a horizontal position, and a first stopper is disposed in front of the proximal end to collide with the front side of the proximal end when the device main body 2 moves forward. and a rotary elevating member of the second delivery part, which is provided with a second stopper that rotates and raises the second part obliquely.

However, according to the conventional device having the above configuration, each of the laminates on the pedestal, which are sent out one by one onto the conveyor board by the first delivery berm, has a front side of the base end of the second delivery part. Until the tail of the second stopper collides, the part is reliably conveyed a predetermined distance by a plurality of feed claws protruding from the bottom surface of the part, but after colliding with the second stopper, the part is tilted diagonally. Since the tile is generally fed in a state where it rotates upward and is kicked out by each feed pawl, the conveyance accuracy is likely to be degraded, for example, due to differences in the kicking force of each feed pawl or frictional resistance between the laminate and the conveyance platform. If the amount of feed by each feed claw changes due to differences in the length of each feed claw, or if the length of each feed claw is different, the feed amount will necessarily change by that amount, so it is necessary to feed the feed amount by a strict fixed distance by each feed claw. This method has a major drawback in that it is unsuitable and cannot be used as a conveyance device for articles to be transported.

The present invention has been researched and developed in order to cope with the above-mentioned drawbacks, and includes: - In the sequential automatic conveyance device for laminated materials constructed as described above, a bumping protrusion is provided on the upper surface of the second delivery bar; At least a portion of the bar behind the protrusion is made of a flexible elastic member (-1 and in front of the protrusion,

[Retrieval of conveyed objects that protrudes toward] - A fourth arm is pivotally mounted to the rear of the proximal end of the arm, and collides with the rear side of the proximal end when the main body of the apparatus is retracted to rotate and raise the arm. A fifth stopper is disposed in front of the base end, and the stopper collides with the front side of the base end when the device main body moves forward to rotate and lower the arm.
This invention relates to an automatic sequential conveyance and unloading device for laminated materials, characterized in that a stopper is provided.

The details of this invention will be explained below based on the drawings of the embodiments.
In FIGS. 1 to 4, reference numeral 1 denotes a trolley-shaped conveyor main body that is pivoted on a guide bar 2 and is arranged to be able to reciprocate in the horizontal direction by a cylinder 3, and has a required length extending forward at the top. The first delivery bar 4 is provided in a protruding manner.

Reference numeral 5 refers to the first delivery bar 4 which is disposed above the main body 1 in parallel with the first delivery bar 4 and is pivotally connected diagonally upwardly by a hinge 6 at the proximal end side of the main body, that is, the rear side. The second delivery bar is also long, and a plurality of delivery claws 7 are protruded from the lower surface of the first half of the bar at regular intervals, and the first delivery bar 4 has a plurality of protruding claws 7 on the upper surface of the bar. A bumping protrusion 8 having a chevron-shaped side surface is provided at the tip, and a portion of the bar having a required length located rearward from the protrusion is made of a slightly thin flexible elastic member 5a.

Reference numeral 9 denotes a conveyance table arranged in front of the first delivery bar 4 at a required interval, and between the bar 4 and the conveyance table 9 is a pedestal 10 that is raised and lowered by a cylinder (not shown). A supply mechanism 11 is provided.

Reference numeral 12 indicates a first stopper disposed on the rear side of the base end of the second delivery bar 5; 13 indicates a second stopper disposed on the front side of the base end of the second delivery bar 5; The second stopper 13 collides with the rear side of the proximal end of the bar when the main body 1 of the apparatus moves backward, and rotates the bar downward to a horizontal position. The bar collides with the front side and urges the bar to rotate upward diagonally from the horizontal position, and these two stoppers constitute the second delivery bar 50 rotating lifting member. Appropriate friction members (
(not shown) to prevent the second delivery bar, which has rotated upward, from unexpectedly rotating downward.

Reference numeral 14 indicates a third portion disposed in front of the protrusion 8 of the second delivery bar.
The stopper is configured to collide with the front surface of the protrusion when the main body 1 of the apparatus moves forward, and temporarily prevent the second stopper 13 from rotating upwardly of the second delivery bar.

Reference numeral 15 denotes a carry-out device main body for taking out transported objects, which is mounted on a guide bar 16 and is disposed in front of the second feed-out bar 5 so as to be able to reciprocate in the horizontal direction together with the transport device main body via a connecting bar 17. Then, attach the conveyed object take-out arm 18 that protrudes toward the tip side of the second delivery bar from the upper part to the main body 15.
is pivotally mounted on the front side of the arm so as to be able to rotate diagonally upward by a hinge 19, and when the main body 15 of the device is retracted, the arm 18 collides with the rear side of the base end to place the arm 18 in a horizontal position. A fourth stopper 20 is disposed to rotate upwardly from the arm, and a fourth stopper 20 is disposed on the front side of the proximal end of the arm.
An automatic unloading device is constructed by arranging a fifth stopper 21 that collides with the front side of the proximal end to rotate and lower the arm to a horizontal position when the arm moves forward. In order to prevent the rotated arm from unexpectedly rotating downward, an appropriate friction member (not shown) is brought into contact with the side surface of the proximal end. Intermediate products of stop-type semiconductors, 23 is the finished product,
24 indicates each chute.

Next, to explain the sequential automatic conveyance and unloading operation of the laminate based on the above embodiment, FIG. 11
A plurality of intermediate products (semi-finished products) 22 of resin-sealed semiconductors to be transported are stacked on the pedestal 10 of the holder 10, and the stack is lifted to a predetermined position between the first delivery bar 4 and the transport table 9. The uppermost laminate is always pushed to the first delivery bar 4.
The positioning is performed using a positioning stopper force as shown in FIGS. 5 to 7 as a known example.

Therefore, when the cylinder 3 is actuated to reciprocate the transport device main body 1, the tip of the first delivery bar 4 sends the uppermost stacked material to a predetermined position on the transport table 9 as it moves forward, but at that time, the transport device body 1 is already Each preceding consignment (conveyance) being sent up
are sent by the respective feed claws 7 of the second feed bar 5, and are conveyed a predetermined distance on the conveyance table until the collision protrusion 8 of the bar 5 collides with the third stopper 14 (see Fig. 2). reference).

After the collision protrusion 8 collides with the third stopper 14, even if the conveyor main body 1 still has room to advance, its advance is blocked, and at that point the second delivery bar 5 is stopped. Even if the second stopper 13 collides with the front side of the proximal end, the bar is prevented from rotating upward, and therefore, as shown in FIG. 2, the portion of the flexible elastic member 5a of the bar 50 is will be bent.

Next, the main body 1 retreats due to the return movement of the cylinder 3, and at the same time, the protrusion 8 of the bar 5 separates from the third stopper 14.
The bar is moved to the second position by the restoring force of the flexible elastic member 5a.
As shown in FIG. 3, the bar 5 rotates upwardly through the stopper 13 and moves backward with the feed pawl 7 and the conveyed object separated from each other. The main body 1 retreats without being hooked at 7 and returned.

When the main body 1 retreats and returns to the position at the start of conveyance (see Figure 1), the first stopper 12 collides with the rear side of the base end of the second delivery bar 5, rotating the bar downward to a horizontal position. At the same time, the main body 15 of the conveying device for taking out the conveyed object is also moved backward by the connecting bar 17, and the fourth stopper 20 collides with the rear side of the base end of the conveyed object take-out arm 180 pivotally connected to the main body 15, so that the arm is rotated diagonally upward from the horizontal position, and the finished product 23, which has been conveyed to the frontmost position of the conveyor table 9 by the rotational rise, is carried out onto the chute 24, and one cycle of conveying and unloading the stack is performed. Once completed, the system enters the next transporting and unloading position, and in this manner, a plurality of laminated objects are reliably automatically transported and unloaded one after another.

Further, the arm 18 that has been rotated and raised is automatically returned to the horizontal position when the main body 15 of the unloading device moves forward and the fifth stopper 21 collides with the front side of the proximal end of the arm, and the arm 18 is automatically returned to the horizontal position for the next unloading. It's about adjusting your posture.

In the above embodiment, illustrations and explanations are omitted, but the intermediate product 22 transported on the transport table is finished as a finished product 23 by a finishing device specially installed during the transport process, and is taken out.

As described above in detail, according to the device of the present invention, unlike the previously described conventional device, there is no need to transport the laminated object with the feed claw when the second feed bar is rotated diagonally upward. An automatic conveyance device for articles that can reliably achieve sequential feeding over a predetermined distance without causing differences in the amount of feed by each feed claw based on the reasons already mentioned, and therefore requires strict feeding accuracy by each feed claw. In addition to being able to exhibit excellent effects as a carrier, the conveyed objects can be automatically carried out in synchronization with the conveying operation, so that the efficiency of successive conveyance and unloading of the stacked articles can be significantly improved.
