Description

Automatic blank stack transport from the

Cutting system for blank feed In the blank stacking system (Fig 1 UST 16), the blanks coming from the cutting press are either in StapelnOst 1 or 2 stacked.

The stacking takes place on a height-adjustable lifting table with an integrated conveyor system.

(Picture 1 UST 17/18).

Once the stack height is reached, the stack is transported through the conveyor system conveyed to a stacking trolley (Fig. 2 + 3 UST 19).

The capacity of this stacking trolley depends on the dimensions of the board stack.

The trolley can also take several stacks (Fig. 3 UST 20/21 - Fig. 4 UST 24).

The stacking trolley itself is parallel to the direction of travel of the cutting press movable, (Fig. 2 + 4 UST 19) in order to be able to accommodate several stacks of blanks.

Furthermore, a conveyor system is integrated in the trolley, around the or the Transport stacks with or without a pallet on an A.G.V. trolley. (Picture 3 + 4 UST 24).

Is the stack of blanks transported with the A.G.V car using Pallet is provided, so the stacking trolley (Fig. 2 + 3 UST 19) receives a lifting fork, which lies between the chain strands (Fig. 3 UST »3).

After picking up the stack or stacks on the stack pick-up carriage by lifting the lifting fork the stack or stacks are raised so that an empty pallet, which is on the A.G.V. trolley (Fig. 3 UST 22) on the stacking trolley is transported. The lifting fork lowers again (Fig. 1 + 3 UST 25) and dips into it the pallet one; the stack of blanks is on the pallet.

The pallet with the stack of blanks can now be removed from the blank pick-up trolley can be transported on the A.G.V. wagon (Fig. 3 UST 26).

From here the A.G.V. car drives to a blank store or directly to the Blank feeding device.

(Picture I + II UZG 2).

The pallet with the stack of blanks is transferred from the A.G.V. trolley to the stacking trolley transported. (Image III UZG 2 + 3).

The lifting fork lifts the stack of blanks from the pallet (Fig. III UZG 13); the pallet is transported back to the A.G.V. wagon (Fig. III UZG 17).

Now the fork can lower completely so that the stack is on the conveyor system of the stacking trolley comes to a standstill (Fig. II UZG 16).

Now individual stacks are placed on the transfer table with the conveyor system transported (Fig. II UZG The stack of blanks arrives at the transfer table into the destacking station (picture I + II UZG 7).

Here the blanks are separated by means of leaf magnets and Transferred to an indexing belt conveyor by lifting and lowering suction cups (Fig. II UZG 17).

To adjust the leaf magnets to the respective board contour, a sample blank is fed into the destacking station (Fig.I UZG 11).

The entire carriage with the clamped sample board is placed between the Leaf magnets raised.

The raised board is a timing belt conveyor that is switchable with Permanent magnets equipped, passed (Fig. II UZG 18).

Any double boards that may have been reported are placed on the associated storage area (Image 1 UZG 8).

This device can be moved backwards transversely to the transport direction.

In order to ensure that the system comes to a standstill when a pile change is required To avoid this, an intermediate piling latch device is provided (Fig. II UZG 19).

This device is capable of a residual pile with a height of max. 50 mm to be taken over.

Remaining stacks and stack return are carried out automatically.

The stack is moved back from the unstacking point (Fig. I UZG 1) and then by a chain conveyor with an integrated running transverse to the transport direction Driving system adopted (Fig. 1 UZG 10) Another chain conveyor (Image I UZG 6; 4) takes over the remainder of the stack or the stack of double blanks from a chain conveyor (picture I UZG 9), and leads it to the A.G.V. car to. If the stack is to be transported on to a pallet again, so is again a stacking table with conveyor system and integrated lifting fork is required. (Image I UZG 4). Automatic blank stack transport from one Cutting system for blank feed The coming from a cutting press 1 (Fig 1) Blanks are in a blank stacking system 2 in stacking nest 1, 3 (Fig 1) or Stacking nest 2 3a (Fig 1) stacked.

The stacking takes place on a height-adjustable lifting table.

A conveyor system 4 and 4a is located on this lifting table.

When the stack height is reached, the lifting table lowers and the stack 8 and 8a is by the conveyor system via an intermediate table 9 and 9a on a Stack pick-up car 5 + 5a (Fig. 2 and Fig. 3) promoted.

The capacity of this stacking trolley depends on the dimensions of the board stack.

The stack pick-up trolley is also able to pick up several stacks. 10-lOb (Fig 4) It can be moved parallel to the direction of belt travel of the cutting press.

A conveyor system 7 is integrated on this stacking trolley (Fig 2 and 3) to the stack or stacks 10 (FIG. 5) with or without a pallet on one A.G.V. car 12 (Fig 5).

In this case, the stacking trolley has a lifting fork 6 (Fig. 3 and Fig 5). This lifting fork lies between the chains. After 'taking up the stack 10 (Fig. 5) the stack is raised by lifting the fork, so that a empty pallet 11 (Fig 5) conveyed from the A.G.V. car to the stacking trolley can be.

The lifting fork lowers again and dips through the one designed for this purpose Palette.

Now the pallet with the stack of blanks can be lifted from the stacking trolley the A.G.V.-car can be transported.

The stack can now be transferred from the cutting system to a blank store or can be transported directly to the blank feeder 13 (FIG. 7).

The stack of blanks with pallet 11 is taken from the A.G.V. trolley 12 (Fig. 8) (Fig 8) transported on a stacking carriage 5 (Fig 8).

The lifting fork 6a (FIG. 8) lifts the stack of blanks through the pallet on, the pallet 6a (Fig. 8) is transported back onto the A.G.V. carriage, the lifting fork 6b (Fig. 8) lowers again.

Now the stack of blanks or, in the case of several, the individual stack of blanks 10-10b (FIG. 9) through the transport system 7-7b (FIG. 9) of the blank feed 10a (Fig 7) are supplied.

A stack return 12a (Fig. 6) can be in the same way as in the blank stacking system.
