Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a workpiece loading device, and more specifically, a forklift tractor for transporting a workpiece carried out from a work line such as a press line to the next production stage by a forklift tractor. A device for loading workpieces onto pallets or baskets in the transport layer, the purpose of which is to quickly load workpieces onto pallets or baskets in accordance with the pace of unloading from the work line. It is.

A press line, an assembly line using spot welding, etc. The method of transporting workpieces between work lines is to load the workpieces carried out from the work line onto pallets or baskets, which are then transported to the next work line using a fork soft tractor. method is commonly used.

More specifically, for example, works that have been pressed in a press line are continuously carried out from a press device while being placed on a conveyor at regular intervals. The works conveyed to the tip of the conveyor are hung on a pallet or stacked in a basket at the tip. Works loaded on pallets or baskets are transported by seven oaklift tractors in units of pallets or baskets to the next work line, that is, the assembly line for spot welding.

However, in recent years, with the advancement of technology in each work line such as presses, it has become possible to shorten the machining time of workpieces that do not have a rod and increase the pace of unloading of the same workpieces. This resulted in a delay in the loading pace during the loading/shrinking work process.

In other words, as a specific example, in the press work line, although it is possible to have the processed soak delivered to the open silver for 5 seconds, in the work process of loading the same work onto a pallet or basket, the work is loaded at a delivery pace of every 5 seconds. This cannot be done using conventional methods, and the reality is that the unloading pace from the press work line is adjusted to match the loading pace. When sorters are stacked flat in a bus nut, no particular problem will occur if the workpiece is a flat cedar-shaped workpiece, such as a flat plate, but if the workpiece's stacked surface is not flat but uneven. In addition, if the unevenness is not symmetrical (front-to-back) and uneven, such as one side being high and the other being low, the workpieces stacked on the second or higher level may be As shown in Fig. 8, the layers are stacked in a vertical state with an inclination toward the lower uneven side. In other words, it is possible to obtain a laminated state only by stacking the warp formed with uneven unevenness on the M''H surface with an inclination toward the lower uneven side. .Hb If we were to stack workpieces with uneven unevenness on the laminated surfaces as described above, if we tried to stack them directly above each other mechanically, the workpieces would collapse as shown in Figure 8. A laminated state of 7xL/2° is obtained. Therefore, the workpiece is formed with irregular unevenness on the laminated surface. In order to stack the workpiece, the stacking position must be changed little by little along the inclination direction each time the stacking is repeated. is necessary.

The present invention is an attempt to improve the conventional situation in view of the above-mentioned actual situation. For example, a pair of left and right workpiece finishing mechanisms are provided at the tip of a work line such as a press, and are movable in a reciprocating manner. Through the reciprocating movement of the mechanism, the workpieces that are continuously carried out from the work line are distributed alternately and loaded onto pallets or baskets 21 times simultaneously, adapting to the pace at which the workpieces are carried out. The purpose of this is to create a bowl that can be loaded quickly, and to prevent irregular unevenness from forming on the laminated surface.
When stacking workpieces in a flat state inside a pass nut, by providing fine adjustment of the reciprocating stroke of the suction mechanism, it is possible to stack the workpieces in an inclined plane according to the stacking surface of the workpieces. It is characterized by the fact that it is possible to do so.

That is, a traverse curler constituted by a pair of traverses is provided at the tip of the unexploded rehabilitation conveyor, and both traverses are provided so as to be movable in the reciprocating direction so as to be able to stop alternately at positions corresponding to the tip of the conveyor. Traversing carts are provided so as to be able to travel in a direction perpendicular to the running direction of the traverse car, and a work suction mechanism equipped with a vacuum gripper is installed vertically on the traversing carts so that they can be raised and lowered freely. , and the above (rubber force −

Next, we will explain its effects.

In the first embodiment shown in FIGS. 1 to 3, the top frame (
1) Below both traverses (a pair of pallets corresponding to the stopping positions at both ends of 3j7 (3B)) 04
04 is placed. In addition, the traverse car (3) stops with one traverse (3A) placed above the shooter (c), and the other traverse (3B) rests on the pallet (b) at the end of the pedestal (1). This shows a state in which the presses stop at corresponding positions. In a situation where the pallets (0404) are placed at both ends of the pedestal (1) as described above and the traverse (3A) is located above the shooter, the press device body) The pressed raniks (b) are placed on the transport conveyor (0) at regular intervals and are transported toward the shooter (2). The workpiece (□□□) force-fed by the same conveyor (0) to its tip position is transferred to the shooter (2).
It slides down the f110 surface. Work lV) is the shooter
2, the suction mechanism (3A) stops above the chute (to).
7) is lowered through the operation of the hydraulic cylinder (0).

Then, by lowering the suction mechanism (7), a state is obtained in which the workpiece (B) is suctioned by the vacuum gripper (01). /<Rei Neem Gripper 0η When the workpiece (B) is suctioned, the same suction mechanism (7
) can be raised again through the operation of the hydraulic cylinder (8), and at the same time, the vacuum gripper 6η attracts the workpiece (B) through the operation of the hydraulic cylinder 00 and moves from the downward position to the horizontal direction. You can get the effect of rotating towards the target.

On the other hand, as described above, the lifting action of the suction mechanism (7) and the rotation action of the vacuum gripper-01> to the horizontal position are obtained, and at the same time, the traverse (3A-) is moved to the rack 1Fj (1).
The effect of traveling toward the end of the cylinder is obtained almost simultaneously. In other words, the traverse (3A) is the shared (1) machine m
(7) (/, l raising action and vacuum gripper-op
The rotation movement from the downward position to the horizontal position is continuous.

Also, in synchronization with the action of the traverse (3A) being sent to one end of the frame (1), the seater 01 is moved to the pallet 04.
It oscillates and rotates in one direction. 047 The same shifter αQ is directly transmitted to the traverse (3A), so that the transverse truck (6) mounted on the traverse (3A) moves in the longitudinal direction of the traverse (3h), in other words, the traverse (3A)
An effect of traveling in a direction perpendicular to the traveling direction 1 of the vehicle is obtained. As the traversing cart (6) travels along the longitudinal direction of the traverse (3A), the alligator (crocodile) is attracted to the vacuum gripper 0◇ in a horizontal position.

From this, only the traversing carriage (6) and suction mechanism (7) can be moved back to the old position while the work V) is suspended on the hangers (C) and (G). On the other hand, as the traverse (3A) moves toward one end of the pedestal (1), a workpiece (support) for reading the bill is placed on the shooter (a).
slides down the slope.

Then, as with my father, the traverse (3A) synchronizes with the movement toward one end of the pedestal (1), and until now the pedestal (1)
The traverse (3B
) travels in the direction of the shooter (a) and stops at a position above the shooter (to) in correspondence with it.

When the upper wrapper (3B) is stopped above the shooter (2), the suction structure (7) on the traverse (3B) side is lowered via the hydraulic cylinder (8) in the same manner as described above, and the chute (i.e. ) It is possible to obtain the effect of adsorbing the workpiece (b) above by the vacuum gripper force, and the effect of rotating the vacuum gripper 09 from the downward position to the horizontal position via the hydraulic cylinder 00, and to perform both of the above operations simultaneously. , and the effect of moving the traverse (3B) toward the other end of the trestle (1) is obtained simultaneously.

Then, when the traverse (3B) has traveled to the other end position of the pedestal (1), the transverse cart (6) mounted on the traverse (3B) is moved to (

At the same time, an effect is obtained in which only the suction mechanism (7) retreats.

That is, through the reciprocating motion of both traverses (3A) and (3B), suction and conveyance of the workpiece (W) and hanging action for the pallet α are alternately obtained at both ends of the pedestal (1).

In the second embodiment shown in FIGS. 4v to 6, when the workpieces (b) are stacked flat in one layer δ in the basket (to),
In particular, workpieces formed with uneven unevenness on the laminated surface

Figure 4 shows a state N4 in which one traverse (3B) has moved to the upper position of the shooter. A letter of condolence M on the same drawing
At t, the suction mechanism (
By making 7) Ti, the workpiece (B) on the chute (A) can be adsorbed by the vacuum gripper (a). The suction machine 1 (7) which has adsorbed the workpiece (B) by the vacuum gripper (01) rises again via the hydraulic cylinder (8), while the traverse (3
An effect of moving B) toward the end of the pedestal (1) can be obtained. Then, in synchronization with the movement of the traverse (3B), nine transverse carts (6) mounted on the traverse (3B) move in the longitudinal direction of the traverse (3B) via the hydraulic cylinder 〇η, that is, the traverse (3B). A movement m that moves in a direction perpendicular to the 4D movement direction is obtained. In other words, due to the movement of the traverse (3B) and the movement of the trolley (6) i; obtained from the simultaneous fishing, the traverse (B) moves up to the end of the platform <1). In the movable part,
Immediately - What is the suction mechanism (7) that suctions the workpiece (w)? The condition in which the device is placed directly above the cloudy V is obtained. Adsorption mechanism (7
) The turnip basket was located directly above the turnip basket (to), and the suction machine (44ry) was lowered by operating the hydraulic cylinder (8), and the suction by the vacuum gripper (0) was released. After that, by raising the suction mechanism (7) again, only the suction mechanism (7) is raised, leaving the workpiece in the basket (toward). The effect of storing can be obtained.

On the other hand, as the traverse (3B) moves toward the end of the pedestal (1) while sucking the workpiece as described above, the other traverse (3A) moves toward the end of the pedestal (]). Therefore, the effect of moving to a position above the shooter (support) can be obtained. And again, this two-car traverse (3A) (3B)
While the is moving, the read-behind work (B) slides down on the inclined surface of the shooter (To).

When the traverse (3A) is stopped at a position above the shooter, the suction 4I! is applied via the hydraulic cylinder (8). lIden (7) v T vh, the workpiece (B) is adsorbed by the vacuum gripper θη, and then raised again, synchronized with the movement of the traverse (3A) towards the end of the frame (]). The same traverse (3A)
The action of moving the horizontal cart (6) mounted above in a direction perpendicular to the moving direction of the traverse (3A) via the hydraulic cylinder Qη, and moving the suction mechanism (7) into the basket (A). Then, the vacuum gripper Qη releases the suction state, and the workpiece CVJ) is left in the basket 1, and only the suction mechanism (7) is raised again, and then the pedestal (1) is lifted again. At one end, the workpiece can be stored in the basket (c).

Then, the above-mentioned action is repeated alternately through the reciprocating motion of both traverses (3A) (3B), so that the frame (
An effect is obtained in which the works QN) are alternately stacked in a flat state in both baskets (c) placed at both ends of 1).

However, when the workpieces (w) stacked in the basket (c) and (a) are formed with uneven unevenness on their laminated surfaces, the workpieces (w) stacked in the basket (c) and (a) are tilted toward the lower unevenness side. In order to obtain a state in which the workpieces are stacked, and therefore to stack the workpiece pattern (which is formed with irregular irregularities on the laminated surface) in this tank, it is necessary to As mentioned above, it is necessary to stack the stacks with the stacking position τ shifted to the uneven side, but in this example, the stacking position τ is shifted to the uneven side of the traverse (3A) (3B).

FIG. 7 is a drawing showing another embodiment of the fine adjustment mechanism in the third embodiment, and includes both traverses (3A) (
The distance between the two traverses (3A) (3B) can be adjusted via a hydraulic cylinder e4 interposed between the traverses (3m). The stacking position of the two traverses (3A) (workpieces stacked in the second or higher stages) can be changed in accordance with the inclination of both traverses (3A) (workpieces @ through the interval Hv between 3BJ).

The present invention is constructed as described above, and includes a traverse car that has a pair of left and right traverses at both ends as described above and is driven by a traverse car, with both traverses having a tip end of a conveyor as a base point. It is provided so that it can move freely across both width directions of the conveyor so that it can run in the width direction, and it can also move in the direction perpendicular to the running direction of the traverse car on both traverses. A horizontal truck is installed, and a pair of suction mechanisms are installed on both horizontal trucks. It is installed so that it can be raised and lowered freely, and the workpieces that are continuously carried out are distributed alternately in both width directions through the above-mentioned two suction mechanisms, and the loading work onto pallets or baskets is carried out by the conveyor. [Thus, it is possible to carry out the filling work simultaneously on both sides of the conveyor, and as a result, the work efficiency is significantly improved.] I was able to do it.

In addition, in the present invention, a traverse is provided on the traverse truck so as to be movable in the same direction as the traverse, and a hydraulic cylinder is interposed between the trappers and the spacing for plucking the traverse car. The distance between the two traverses can be adjusted via the same hydraulic cylinder, so that the stroke of the traverse car can be adjusted. When the workpieces to be formed are stacked flat in a bus nut, the first, second and higher stages are stacked: -
What is the position of the stack relative to the workpiece? It is now possible to sequentially change the inclination direction in accordance with the direction of inclination, and it has become possible to stack workpieces formed with unevenness of 1ρ on the laminated layer surface with an arbitrary inclination angle. .
