Description

Slab feeder machine and the like.

Object of the invention

The present invention relates to a machine slab feeder and the like, to supply slabs of slate or any stone, and even tiles or other portions essentially flat, to another machine or process.

Background of the invention

At present several machines are known that work with slabs or boats of stone materials. These machines mainly comprise bands where the slabs are they must have one at a time to be processed, being expelled after the process with the cooperation usually of cylinders of expulsion.

To feed these machines it is necessary arrange the slabs one by one. These supposes a inconvenient, since the slabs are normally piled up forming batteries

The placement of the slabs one at a time one is usually done manually, or using means that They work at low speed. As a result you get a productivity penalty.

Description of the invention

The machine of the invention has a optimal constitution to produce a continuous feed and to high speed slabs, one at a time, for processing or processing later.

According to the invention, the machine it comprises an elevating feeder band, on which deposit the slabs piled up forming stacks, up to one discharge position.

In the unloading position act means of  download multiple alternatives, which download the slabs to high speed, usually depositing them on another band conveyor that forms a certain angle with the belt lifting feeder.

As the pile height decreases slabs, during unloading, the lifting feeder belt goes raising its position to leave the slab at all times scope of alternative multiple download media.

Brief description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to an example preferred practical implementation of it, is accompanied as integral part of that description, a set of drawings where with an illustrative and non-limiting nature, what has been represented next:

Figure 1 shows a perspective view of The machine of the invention.

Figure 2 shows a side view schematic of the alternative multiple download media of the machine of the invention.

Figure 3 shows a schematic detail front of the alternative multiple download media of the machine of the invention.

Figure 4 shows a schematic detail in alternative multiple download media plant of the machine of the invention.

Description of a practical embodiment of the invention

The machine (1) of the invention comprises a lifting feeder belt (2) of stacks (3) of slabs (4) of stone material (for example slate), equipped with vertical elevation to go ascending as the battery (3). The lifting means in this non-limiting example of the invention consist of a vertical spindle (5) conveniently geared to the frame (6) of the lifting feeder belt (2).

In the extreme frontal zone of the band lifting feeder (2) a stop (7) has been provided that prevents malfunction case that slab batteries fall through that side.

It also comprises the machine (1) of the invention alternative multiple discharge means (8), which increase the working speed In this non-limiting example of the invention It comprises two groups (9a, 9b) of suction cups (10) that move alternatively and in opposite directions in a movement of sway. They are also mounted on two lifting pistons (11) that produce their descent at the ends of their movement to catch and release the slabs, and their elevation during the journeys back and forth. The slabs are unloaded in another band top and aligned or oblique conveyor (20) in plant with with respect to the direction of the lifting feeder band (2), which It is usually part of another slab cutting machine, not represented. Also the conveyor belt (20) can form part of the feeding machine (1) of the invention.

The pistons (11) are mounted in turn in some supports (12), each of which is in solidarity in convenient points to different branches (13a, 13b) of a chain (13) upper longitudinal. The chain (13) runs with movements reciprocating between vertical pinions (14a, 14b) ends, being at minus one of them driven by an engine (15). With this configuration is achieved that the lifting pistons (11) are move in opposite directions with reciprocating movements.

The supports (12), in turn, are guided by means of rollers (16) in lateral guides (17) included in the frame (18) of the machine (1).

Operation is as follows: batteries (3) of slabs (4) deposited in the lifting feeder belt (2) move forward to be in the area of action of the media alternative multiple downloads (8). Then the groups (9a, 9b) suction cups (10) alternately unload the slabs of a in one, taking in each step the upper slab and depositing it in the conveyor belt (20), while the spindle (5) is raising sequentially the lifting feeder band (2) as it goes producing the discharge, to place the slabs within reach of suction cups.

Claims (4)

1. Slab feeder machine and the like, which has a frame (18), and which feed the slabs one by one to other machines or processes; characterized in that it comprises an elevating feeder band (2) of stacks (3) of slabs (4); as well as alternative multiple discharge means (8), comprising two groups (9) of suction cups (10) mounted on two lifting pistons (11) fixed at points suitable for different branches (13a, 13b) of a chain (13) superior endowed with reciprocating movements; the chain (13) is mounted between vertical pinions (14a, 14b) being at least one of these motorized; all this in order to produce that the lifting pistons (11) move in opposite directions with reciprocating movements, and their descent occurs at the ends of their movement to catch and release the slabs, and their elevation during the outward and outward paths return. 2. Machine according to claim 1 characterized in that the lifting feeder belt (2) comprises a frame (6) conveniently engaged to a spindle (5) in order to produce its elevation. 3. Machine according to claim 1 characterized in that in the final end zone of the lifting feeder belt (2) it has a stop (7) anti-fall of the slabs (4). 4. Machine according to claim 1 characterized in that the lifting pistons (11) are mounted on supports (12) guided by rollers (16) on side guides (17) that are part of the frame (18) of the machine (1).
