DE2341235A1 - Mechanical handling system for flat materials - transfers plate like objects from conveyor to pallet with continuous automatic lining up - Google Patents

Abstract

Automatic and continuous lining up method of edges or stacking of easily deformable flat objects such as thin rubber plates, finished woven material or asbestos cement plates. The objects supplied by a conveyor band are transferred to band frames which are moved forward, lowered, moved back and raised in a predetermined operating cycle. The forward movement of the band frame with the belt at rest during the beginning of the backward movement with the belt running the objects are transferred to a pallet positioned below the frame.

Description

Patent application

Process for automatic, continuous and edge prerading Placing or stacking easily deformable, flat objects, such as cut-to-length, thin rubber sheets, calendered fabric, asbestos cement board and the like, as well as Facility for carrying out the procedure.

It is known, easily deformable, flat objects, such as thin rubber sheets, which continuously from a calender Coming as a web produced and cut to length on a conveyor belt to be removed from this by hand.

This type of treatment is costly and requires precise execution with straight-edged stacking. In order to circumvent these difficulties, the invention proposes in front of the items delivered by the conveyor belt

on tape '^ place to be delivered in a particular The work cycle can be moved forward, lowered, moved back and raised again in such a way that the forward movement of the Well-receiving belt frame with the belt at rest, the objects delivered by the conveyor belt are taken over by him and after lowering when moving back the belt frame while the belt is running to the one below Pallet or the like «.

The belt frames are located below the conveyor belt and the belt frame at the front takes over its advancing movement the object or items running off the conveyor belt, with its advancing movement approximately corresponds to that of the conveyor belt, and there is this after lowering during its return movement with the belt running on an underlying pallet or the like.

For the uninterrupted acceptance of the items delivered by the conveyor belt Items are preferably four or more such tape racks used for the cycle of movement, with the corresponding number of pallets, which are filled one after the other, so that the respectively filled pallet is driven out and can be replaced by an empty one without having to interrupt operation.

The method according to the invention and the ones required for it Setup will be based on a drawing in the following described in more detail. Show it:

FIG. 5 A parallel arrangement to FIG. 1

Fig..6 A vertical section along the line VI-VI of Fig.

According to Fig. 1, B 1 denotes the conveyor belt delivering the objects, which, for example, consists of a calender E come. In the example below B 1 there are eight belt racks B 2 to B 9 moving in rhythm The direction of the arrow can be moved forward, lowered, moved back and raised again to the starting position.

The front belt frame B 2 is loaded and is lowered while the belt frame B 3 behind it the from the conveyor belt B 1 continuously delivered objects takes over. All band racks B 2 to B 9 are moved cyclically by a common drive, as will be explained in more detail below.

In the example of FIG. 1, the belt of the belt frame b is used to place the objects on the pallet P 1 driven, causing the good on the one below Pallet P 1 is deposited. If the pallet P 1 is full,

so it is extended and takes its place Pallet P 2 from the belt above it, B 7 is loaded. The pallet P 3 can also be loaded in the same way, so that there is always enough time available to replace the loaded pallets with unloaded ones.

The Pig. 2 and 3 show the movement scheme of the belt drives B 2 to B 9 seen from the side or from above, only two belt drives B 2 and B 3 being shown.

This band. ^ Estelle are at two opposite each other in length offset chain drives 10, 11 attached via driving pins 12, 13 and are held across the corner. The rotating drums The band racks rest e.g. in a frame, not shown, made of pressed sheet metal, for example, and are without any drive for the strap.

Like the belts of the band, there is a place to hand over their load 4 shows, for example, in a vertical section according to the line IV-IV of FIG. 2.

The chain wheels 10, 11 are each driven by an electric motor 16, 17 here. Originally the belt frame B 3 is located the pallet P 1, next to her left and right a friction wheel 18, 19 are arranged, which have a motor 20, 20 a be set in motion when the conveyor frame runs back,

so that its load is deposited on the Palebbe P 1. Another possibility is to use the strap of the band frame to be held at the top close to the rear drum, for example by means of a lock or pincer-like clamp, so that When the belt rack moves back, the load is deposited, but the lock must be re-activated in good time To get picked up. In the case of a friction wheel drive of the belt, the detachment from the drive takes place automatically by running down of the belt from the friction wheels 18, 19 »

FIG. 5 shows a parallel arrangement to FIG. 1 which is used if the goods delivered by conveyor belt B 1 have to be placed on their back, e.g. around the underside of the goods with an adhesive layer or the like. This can be used, for example, for protectors for pneumatic tires.

For this purpose, the direction of rotation of the band racks B to B 9 is reversed, and the band racks are in front of the Conveyor belt B 1 and pass under the latter in the work cycle.

The objects delivered by the conveyor belt B 1, e.g. the cut-to-length protectors are placed on their backs during the transition to the band frame B 2, and the rest of the work is carried out the process is analogous to that of FIG. 1.

Since protectors and similar smaller parts are preferably stored in flap trolleys, according to the invention

the deposit initially on an auxiliary conveyor belt B 10, whose direction of travel is transverse to that of the belt racks. Under this auxiliary conveyor belt there is another particularly flat distribution belt B 11, which can be extended to the left and right of the auxiliary conveyor belt, and the loading from Auxiliary conveyor takes over. Depending on the direction of movement of the auxiliary conveyor belt B 10 is loaded via the distributor belt B 11 either on the left or on the right Side of the stationary auxiliary conveyor belt B 10 and from there for feeding into the left respectively. right-hand flap trolley.

JPig. 6 shows such an arrangement in vertical section the pig. 5.

The auxiliary conveyor belt B 10 is located under the belt frame B 3, which transfers its load to the distributor belt B 11 which is just to the right of it. This band alternates with the held The upper belt over to the other side and transfers its load to the flap trolley below. During this time, a filled flap trolley standing on the other side can be replaced.

To. The flap trolley is used to fill each floor lowered to one level and extended when full. The flap carriages are labeled 21 and 22. Leave the dependencies of the individual movement processes can be controlled electrically without difficulty and monitored centrally using known devices.

The representations are only to be regarded as examples, they allow structural changes.
