Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feeding device for a plate dividing saw, for example, a lift table for accommodating plate stacks formed from material plates, and a carrier capable of traveling horizontally above the lift table. This carrier has, at right angles to the feeder, a number of plate catch units with catch elements spaced apart from each other, which lift towards the roller accelerator connected in front of the plate split saw. It is intended to separate the plates from the plate stack on the table.

[0002]

2. Description of the Prior Art Feeders for plate split saws form an insert wagon with a number of catch elements for removing plates from the plate stack, which carry out a self-moving carrier plate insertion movement. Such an insert wagon has a relatively long dimension at right angles to the insertion direction, so that plates with a length of several meters can also be fed to the plate-splitting saw, so the wagon structure is designed to be correspondingly robust. There must be. The wagon structure is accordingly correspondingly predominant in weight.

[0003]

For each plate transport, therefore, all heavy insertion wagons must be returned in the direction of the roller accelerator and back to its original position.
The mass that is accelerated and decelerated at this time largely determines the working cycle of this type of feeder.

The problem underlying the present invention is to significantly increase the working cycle of the feeder for plate split saws for removing plates.

[0005]

The problem underlying the invention is solved by the features of claim 1. The plate catch elements are reciprocally moved by the drive device relative to the carriers on which they can travel, such carriers being initially set relative to the plate stacks to be removed during installation of the feeder. Can be fixed in a fixed position.

According to the construction according to the invention, the moving weight for removing the plate is significantly reduced, which can significantly increase the working speed or the cycle time. The carrier with the catch element therefore likewise forms a further mobile wagon which can be driven into the necessary adjusting position in order to remove irregularities in the plate stack, but with the plate insertion function. Does not include.

[0007] With the construction of the invention according to claim 2, a reliable mode of operation of the plate catch element is such that the plate material withdrawn from the plate stack is a thin flexible plate of only a few millimeters, for example hard fibers or the corresponding. Guaranteed even if the material. Besides, due to the suction head belonging to the plate catch element, heavier plates can also be tilted slightly before the catch, or work with another transport carriage to lift and transport only by suction of the plate stack.

A preferred construction of the catch element is claim 3.
Is the subject of. In this case, the arrangement is formed by tow hooks, which are each pivotally mounted on the guide carriage of the carrier, which is lifted by the swivel device when the guide carriage is returned to its initial position, over the plate stack. When crossed over, it is not possible to contact or damage the plate side above the upper deposition plate.

In a further advantageous configuration of the invention, the individual guide carriages or the towing hooks of the catch element can be moved by a common drive according to claim 4. This can technically be advantageously carried out according to claim 5. The catch element or the towing hook as well as the guide carriage for transporting the plates have only to make linear movements opposite one another, so that in this case it is advantageous to provide an advantageous solution of their drive.
It is.

The swivel device, which converts the tow hook into the upper removal position during return, operates without a special drive, which is the subject of claim 8. The movements of the tow hook, the guide carriage and the swivel device are in this case provided solely by the drive or cylinder group, and claim 9 shows an advantageous solution for driving the actuating carriage of the swivel device.

The structure proposal according to claim 10 makes it possible to double the number of cycles of the feeder in a technically simple manner. This is provided with two tow hooks for each plate catch unit of the carrier, one of the tow hooks being in the take-out start position at the beginning of the plate take-out, the other in the take-out end position.
Achieved by being distributed to each other. During each forward / backward movement of one of the inter-vehicle parts of the traction mechanism, and therefore one of the two traction mechanisms is controlled to its take-out starting position, one plate is reversible during all reversal of the movement of the inter-vehicle part of the traction mechanism. Are removed from the plate stack.

[0012]

The plate feeder for a plate-splitting saw is a fixed structural unit with a roller accelerator connected in front of the machine base of the plate-splitting saw. An insertion wagon feeds the plate feeder with individual plates pushed from the plate stack between the drivable accelerating rollers below the roller accelerator and the descentable pressure rollers above. As soon as it is reached, it is picked up by its rollers and transported at a much higher transport speed to the machine base of the plate split saw. As soon as the insertion wagon has traveled a relatively short transport distance and the previously fed plate leaves the roller accelerator, the roller accelerator will already have another plate for plate deposition,
This is possible.

The plates, for example the material plates, which are placed on the machine base of the plate-dividing saw, must then be aligned individually or as a plate package with flat edges, which are, for example, rollers on the machine base. This can be done with a delivery wagon with an elevating catch element that can travel horizontally between the accelerator and the plate split saw. These catch elements are oriented with respect to the rollers of the roller accelerator such that they can be lowered into the rollers after the plate resting on the machine table, followed by the plate or plates prepared on the machine table. The stack is moved in the direction of the plate-dividing saw, which is then controlled upwards and hits a stopper which extends parallel to the cutting plane of the plate-dividing saw. Instead of this, instead of an insertion wagon, this stopper can also be controlled for plate alignment in the direction of the stopper surface provided after the roller accelerator.

The roller accelerator and insertion wagon are therefore
Two structural units that can be driven and that operate independently of each other. The role of the roller accelerator in this case is to work with the insertion wagon to lift heavy weight plates, e.g. by suction lowering elements, from the plate stack and use the transfer wagon to lay around the roller accelerator on the machine table. That is not to allow it. This is the state of the art within the applicant's company that cannot be documented.

In the plate feeder according to claim 1, there is required a structure in which the roller accelerator of which the delivery wagon works together with the insertion wagon enables the transport corresponding to the heavy plate from the plate stack to the machine table. This is claim 11
Solved by the features of. The delivery wagon is thus also a component of the roller accelerator, which is equipped with at least one upper pressure roller, which also allows the transport of the plate further by at least one acceleration roller and one pressure roller, and in some cases the machine. Alignment of individual plates or plate packages placed on the table is also possible by applying the angle stopper.

According to a twelfth aspect of the present invention, a reconstitution of the present invention comprises a transportable carrier and a delivery wagon for plate deposition for transporting plates with heavy or sensitive surfaces, bypassing plate transport by roller acceleration. To be used directly on the machine table. Similarly, it is possible to move a relatively thick individual plate, or a plate package consisting of relatively thin individual plates, over the accelerating rollers and onto the machine platform only by means of a carrier which can also be moved, in which case the delivery wagon is Proper positioning above the machine platform allows it to remain in a rest position.

In the reconstitution of the present invention according to claim 13 or 14, when a heavy individual plate or plate package is transported, a large height deviation occurs between the plate take-out surface and the plate mount surface of the machine base. It has the advantage of not being. In the case of the construction according to the invention, the upper part of the usual roller accelerator is therefore formed by a delivery wagon, which is equipped with a lowerable catch and / or suction element for transporting individual or plate packages. Can be configured for.

For the transport of the individual heavy plates, all the wagons can advantageously be connected for the purpose of their drive by at least one endless traction mechanism which is diverted and driven through the diverting rollers. it can. Other advantageous configurations of the invention are the subject matter of the appended claims.

Embodiment 2 FIG. 1 shows a side view of a plate feeding device, and FIG. 5 shows a longitudinal sectional view through a connecting device for driving connection of a traveling unit of the plate feeding device. This feeding device is derived from a stack, for example a plate stack 2 formed from material plates.
The storage unit 11 for 0 is provided. The housing can be formed by, for example, a lift table. From the plate stack 20, individual plates 16 or plate packages need to be transported onto the machine base 14 of a plate split saw, not shown.

For this purpose, in a known manner, a horizontally running insert wagon (not shown) is used, which insert wagon is provided with a plate catch element which can be raised and lowered appropriately or, as shown, a plate stack. 20. Any one of which comprises a runnable, fixed carrier 26 for transporting plates above 20, which carrier is fitted with a plurality of plate catch units 34 which are responsible for plate movement. , They operate independently of the carrier 26, so that in the case of a stationary carrier 26 the plate withdrawal takes place.

The carrier is followed in a known manner by a roller accelerator 12 and a plate catch unit 34.
From the plate stack 20 is captured and the plate 16 is captured and fed to the machine platform 14 at a high transport rate.

The roller accelerator 12 has a large number of drivable lower accelerating rollers 2, which are preferably axially spaced from one another, and are of the same number and are approximately in their axis for plate transport. It comprises an upper descentable pressure roller 4 on a vertical plane aa which houses the drive shaft 3 of the acceleration roller 2.

In addition, a delivery wagon 21 is still provided between the insert wagon or the movable carrier 26 and the plate-splitting saw, which is no longer shown, which, like the carrier 26, has a plate stack 20.
It is possible to run and fix above the machine base 14 and above the guide rack 24 belonging to it. In this case, both wagons 26, 21 can be driven individually or in common through a common drive, in particular under program control.

The delivery wagon 21 is at the same time the roller accelerator 1
The pressure roller 4 which is a part of the upper part 2 and the upper part of the pressure roller 4 are provided in the delivery wagon 21 by the cylinder device group 5, respectively.
You will be guided to get up and down in the proper way. In addition, the transfer wagon 21 is further provided with plate catch elements 6 which can be raised and lowered, which elements can each be formed, for example, by a piston rod of a cylinder device group 7. These elements are arranged laterally offset on the upper pressure roller 4 and are controllable downwardly between the acceleration rollers 2 in their vertical plane aa to their plate catch position. Furthermore, the group of cylinder devices 7 is preferably arranged after the upper pressure roller 4 when viewed in the plate transport direction.

Cylinder device group 7 and upper pressure roller 4
Are held on a common horizontal member 8 of the delivery wagon 21. The accelerating roller 2 or the machine platform 14 is not shown for the sake of simplicity, but is preferably vertically steplessly adjustable.

The drive 35 is formed by two traction mechanisms, preferably toothed belts 29, each guided around the diverting roller 23, which are endless and extend into the plate transporter. Are facing each other at the same height. Alternatively, the traction mechanism can be formed by a chain or rope, for example.

The carrier 26 or, in the alternative, at least one of the feeding devices, not shown, is guided on an insert wagon, a transfer wagon 21, and possibly also on a guide rack 24 between the two traction mechanisms. Another wagon,
These are specially programmed in a suitable manner with the same inter-car part 27 of the toothed belt 29, for example a clamping surface 90 and a linearly movable actuating key (clamp) 9.
Wagon 26, 2, adjustable by 2
The inter-vehicle portion 27 can be connected to the first fastening mechanism by partially fastening and fixing. The actuating key 92 and the clamping mechanism 94 are in this case guided at the same time in a common guide casing 96 of the coupling device 98 with the clamping surface 90.

When a predetermined number of plates, such as hard fiber board or plate packages 22, are transported on the machine table 14 or stacked on the machine table, the removed plate material will also be the first. If the edges have to be aligned flat for trimming, the transfer wagon 21 will move towards the fixed carrier 26 in the take-out position by the automatic coupling to the belt inter-carrying part 27 and finally the plate. The catch element 6 is behind the plate package 22.

The toothed belt 29 is then controlled in the opposite direction, at which time the plate package 22 is moved, for example by the delivery wagon 21, in the direction of the upwardly pivotable plate stopper 15, for example. Subsequently, the plate stopper is controlled to its released position, so that the plate package 22 is further fed to the feeder one after the other for edging and splitting, for example by means of a transfer wagon 21 which works with the headway portion 27 of the toothed belt 29. You can move. However, it is also possible to use the plate stopper 15 for the plate alignment or to move this stopper in the direction of the stopper surface provided after this for the roller accelerator 12.

The delivery wagon 21 can be additionally or exclusively connected with a negative pressure source, as shown in the plate catch unit 34 of the movable carrier 26, and can be moved up and down by a cylinder device group 86, for example. There may be a suction head 82 arranged. This allows the delivery wagon 21 to likewise upwardly control the plate stack 20 when the upper pressure roller 4 is raised, from which it works together with the suction head 82 of the carrier 26 to lift a particularly heavy individual plate 16. Next, the two units 26 and 21 which can be driven are provided with an inter-vehicle portion 27 having both teeth.
And can be moved above the machine base 14 to lower the plate.

Due to the splitting of the roller accelerator 12 according to the invention, the roller accelerator is no longer in any way obstructed by the plate to be moved onto the machine platform 14 and the plate 16 passes through the lower accelerator roller 2 of the roller accelerator. You can Depending on the choice of the control program, the wagons, which are in this case driven by toothing, can be controlled in the same direction in common, or individually, optionally with different distances, in opposite directions.

In particular, if the traversable units 26, 21 are intended only to have only the suction head 82, the third traversable unit may form a delivery wagon, for example with only the usual vertically movable catches. Yes, this delivery wagon takes on the plate feed to the plate split saw. The structure of the guide part 24 may comprise only horizontal guide rails, on the underside of which the plate catch unit 34 is provided on a transversely arranged transverse member or at least one insertion wagon. I can do it. In this case, one traction mechanism would be sufficient to drive all the co-towed units.
