Abstract

Refinements in patent 200500786, a machine for the automatic feeding of slate trimmers, which has a guide (2) that extends beyond the entrance area in the conveyor belt (1) of the trimmer, interposing between this band ( 1) and the slate plate unit feeder (4) a first conveyor belt (3), not aligned with the previous one (1) and consequently oblique with respect to the lateral guide (2), on which the parts impact the end of its route through said primary guide (3), so that they perfectly adhere to said lateral guide (2) by the own inertia of the pieces when moving.

Description

Refinements in Patent No. P 200500786: "Machine for automatic feeding of trimmers slate".

Object of the invention

The invention relates to a series of improvements introduced in a machine that feeds on automatically a slate trimmer. Specifically these improvements affect the area of the feeder itself said of the trimmer, which consists of a conveyor belt which laterally presents a guide on which it adheres, laterally aligning each piece that enters said band, of so that the pieces move aligned so that the plates of slate are square with a straight cut made by the devices located in its path.

These improvements can be introduced in a new machine, but can also be attached to machines trimmers already in operation.

Background of the invention

The only automatic feeding machines of slate pieces previously placed in a stack are the ones that They are the subject of the main patent.

When feeding in a trimmer is manually perform the operator, when introducing the piece of slate the belt by pushing it against a lateral guide, parallel to the trimmer travel belt. However, when the automatic feeding is necessary some mechanism to perform this operation since if the piece is not aligned with said guide a perfect cut of the slate piece cannot be guaranteed so that they leave squared forming perfect rectangles, since the cutting devices are placed in a position according to said band. In the main patent the feeding system deposit each slate plate, or the material to be trimmed, on a band through which it advances towards the base of the trimmer attached to the feeder.

Description of the invention

The improvements that have been introduced in  this machine affects said lateral guide, which extends longer beyond the entrance area in the conveyor belt of the trimmer. It is also planned to interpose, between this band and the slate plate unit feeder, a first band conveyor, not aligned to the previous one and consequently oblique with respect to the lateral guide, on which the pieces impact the  end of its tour through said primary guide, so that perfectly fit said lateral guide by the inertia of the pieces when moving.

Description of the figures

To complement the description that is being performing and in order to facilitate the understanding of characteristics of the invention, is attached herein descriptive a set of drawings in which, with character Illustrative and not limiting, the following has been represented:

Figures 1 shows a plan view of the machine for automatic feeding of slate pieces, provided of the improvements object of the present invention.

Preferred Embodiment of the Invention

As you can see in the figure the machine automatic feed object receives a package deposit in the roller or motorized introduction belt (6) that carries the slate plate stacks to the charging area of the lifting platform, at which time a motor-reducer drives a drive spindle linear motion car that supports the lifting platform (5), starting to turn to raise the raw material stack to that this can be captured by the unit feeder (4) of slate plates that, starting from a pile or pile of plates, extract one by one by placing them in a primary conveyor belt (3) which is oblique with respect to the line defined by the feeding band (1) in the trimmer.

As shown in the figure the guide (2), on which the piece is fastened laterally, it is arranged parallel to the conveyor belt (1), on the opposite side to which place the feeder (4), and extend towards the entrance beyond of said band in an undefined portion of the primary band (3) located at the beginning. This guide, once the plates are tight slate to it, allows its scrolling aligned to get perfectly squared cuts and thus obtain pieces Uniform and rectangular.

Between the band (1) and the unit feeder of slate plates (4) a first conveyor belt is observed (3), not aligned to the previous one (1) and consequently oblique with with respect to the lateral guide (2), in which the feeder (4) goes placing piece by piece, moving first along this band (3) until it connects with the band (1) that pick up and move to the trimmer. As the primary band (3) is oblique with respect to the band (1) and consequently with with respect to the lateral guide (2), forming an angle with them, the piece that moves through this primary band (1) impacts at the end of its route against said guide (2), perfectly adhering to she and consequently enter the band (1) perfectly aligned and tight to the lateral guide.

Once nature is sufficiently described of the invention, as well as a preferred embodiment, for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not involve an alteration of the essential features of the invention claimed in continuation.

Claims (1)

1. Refinements in patent P 200500786 per machine for automatic feeding of trimmers of slate or other sheet materials that are arranged in piles or lots of which it is necessary to extract one by one to place it in the plate trimmer consisting of a conveyor belt (1) laterally presenting a guide (2) on which it is attached laterally the piece, so that it moves aligned with said band (1) so that the slate plates come out squared and with a straight cut made by the cutting devices located in its path and between the slate plate unit feeder (4) and the conveyor belt (1) there is a first band of introduction (3) not aligned with respect to the conveyor belt (one) characterized because the guide (2), extends laterally along of the conveyor belt (1) and the introduction belt (3) the guide (2) being parallel to the conveyor belt (1) and oblique to the introduction band (3) resulting in the slate plate deposited in the introduction band is pushed in the direction of the conveyor belt sticking to the guide (2) and moving forward aligned to this.
