Definitions
- the present invention refers to an exfoliating machine for slate pieces that significantly improves the process of exfoliating slate pieces by getting on the side faces of the corresponding block to exfoliate a better tightness, detail this very important to get a clean quality cut.
- the machine of the invention is more versatile, while at the same time high productivity is achieved with respect to other conventional machines for the same purpose.
- the machine is responsible for manipulating two blocks to exfoliate to place them in a static position and then proceed to exfoliate by applying pressure with a blade to initiate an incision and fissure acting in successive phases on the lateral faces in cruise planes parallel to the bases of the block, bases arranged in vertical planes, so that by means of said pressure and subsequent injection of pressurized air by the cruise plane, the corresponding slate pieces will be obtained in successive phases.
- slate piece scrubber machines which incorporate means for statically holding a slate block with its bases arranged in vertical planes.
- French invention patent FR 2290051 describes an exfoliation procedure that is performed with a fissure start along one of the sides or side faces of the block, so that the corresponding separation with the plane of incision of the blade is produced by traction using suction cups that are applied against the opposite bases of the block, said suction cups being connected to a vacuum source.
- the invention patent No. 513613 describes an exfoliation procedure characterized in that the beginning of the fissure is carried out practically over the entire length of one of the sides of the block that joins the bases thereof and that borders a closed chamber, inside of which a pressure is established momentarily higher than the ambient pressure that reigns on the opposite faces of the block.
- the invention patent number 9100276 referring to another exfoliation process characterized in that it comprises the following phases: provision of a cutting blade provided with a cutting edge that determines a straight alignment; arrangement of the block to be exfoliated so that said lateral edge will be accessible to said blade; application of said edge to said side edge; actuation of said blade for the introduction of the edge in the slate block, causing a short crack in it; and injection of a pressurized fluid into said crack until the total division of said slate block to exfoliate.
- the slate piece exfoliating machine that constitutes the object of the invention is characterized in that it comprises two work stations and a mobile carriage carrying a cutting blade that strikes a top side face of the slate block previously placed in a stable and static manner in a central area of one of the two work stations.
- Another feature of the invention is the incorporating a jaw comprising in a first embodiment two sets of facing rollers, each of which has pairs of supporting collateral rollers and a central roller of soft material that seals the cruising plane or cutting plane during the process of separation at the time of cutting the cutting blade on the upper side face of the slate block arranged vertically with its bases placed in two vertical planes.
- each central roller is replaced by a pneumatic mattress with a rigid base.
- Both the cutting blade and the two sets of facing rollers are supported by the mobile carriage suspended superiorly from a pair of transverse guide bars to be able to position the said carriage assembly in correspondence with one or another work station arranged in two longitudinal directions parallel.
- a longitudinal bed of rotating rollers is located that is interrupted in a central transverse area where there are two tilting supports to turn and place the slate block in the correct position to proceed later to obtain the different laminar slate pieces by means of the cutting blade that will impact on the upper side face of the corresponding slate block initially dragged by the rotating rollers to the respective tilting support located in the central transverse area, in correspondence with which the mobile carriage is located. it will run over the slate block that is driven in the aforementioned transverse guide bars.
- the blade moves vertically to separate the different pieces of slate using a linear actuator, such as an oleohydraulic or pneumatic cylinder.
- a linear actuator such as an oleohydraulic or pneumatic cylinder.
- the block is held by one of its bases against a seat of the tilting support, while on the other even base they press in a controlled manner other front linear actuators.
- a slate block supports in principle by one of its bases on the respective longitudinal roller bed of one of the work stations, dragging it to the respective tilting support located in the central transverse area of the machine, tilting support which will turn the slate block 90 ° until it is placed in a position where its bases will be arranged in vertical planes, slate block that will remain supported on said tilting support, while the static position of the slate block is ensured through the front linear actuators referred to above.
- the mobile carriage is placed on top of the slate block so that by means of the cutting blade it presses on the upper side face of the slate block in correspondence with a cruising plane or cutting plane parallel to the bases of the block slate, to then blow air under pressure in the incision made to facilitate exfoliation, so it is important that the air does not escape from the sides of the slate block and if below, once the exfoliation is finished. Therefore, the new sealing system based on a central roller with a rubber coating whose generator contacts the surface of the block is created, creating the necessary closure, after pressing on said side faces of the slate block. Said necessary closure can also be made with the pneumatic mattress replacing the central roller.
- Figure 1 Shows an elevational view of the slate piece scrubber, object of the invention. Said pieces of slate are obtained from a block through an exfoliation process.
- Figure 2. Shows a profile view of the machine of the invention.
- Figure 3.- Shows an elevation view of the scrubber machine.
- Figure 4.- Shows a plan view of the machine of the invention.
- Figure 5. Represents a view of a part of the machine that essentially shows a jaw provided with a roller of soft material that seals the cutting plane during the exfoliation process of the slate block.
- Figure 6. Represents a view similar to the previous one where the jaw incorporates a pneumatic mattress replacing the central roller of soft material.
- the slate piece exfoliating machine comprises a frame that supports two longitudinal beds of rotating rollers 1 that rotate by means of two motor-reducers 2 while its continuity is interrupted in a central transverse area 2 where there are two tilting supports 3 with an angular structure in the form of "L", so that in the initial position, the major branch of such tilting supports 3 is located in the same horizontal plane as the longitudinal beds of rotating rollers 1, on the which in principle support the slate blocks 4 by one of their bases, being dragged to place them on the respective tilting support 3, at which time, the it will swing through a larger oleohydraulic cylinder 5 until it is placed in a vertical position in which the major branch of such a tilting support 3 will be arranged in a vertical plane just like the bases of the slate block 4, on whose free base it will press a pair of Front oleohydraulic cylinders 6 to ensure the stability and static clamping of the slate block 4.
- the smaller branch of the tilting supports 3 constitutes a seat base 7 adjustable in height to adapt the height of the slate block 4.
- a mobile carriage 8 suspended and guided in a pair of crossbars 9 fixed at its ends to the machine frame.
- This mobile carriage 8 carries a cutting blade 10-10 'and also a jaw 11-11' which in a first embodiment comprises two groups of vertical rollers, these groups each of which includes a central roller 12 of elastomeric surface and two pairs of support collateral rollers 13, so that the central roller 12 seals the cutting or separation plane of the slate block 4.
- the blade 10-10 ' is moved by a vertical cylinder 14.
- the central roller 12 is replaced by a pneumatic mattress 12 'with a rigid base 18, so that in this case the pneumatic mattress 12' is the element that seals the cutting plane of the slate block 4.
- an air pressure system can be included that will allow the introduction of pressurized air into the pneumatic mattress 12 ', this one being better adapted to the irregularities presented by the slate block 4.
- the structure of the cutting blade may comprise a convergent structure 10 of conventional configuration or comprise a modular structure 10 'formed by several blade portions arranged in the same plane vertical
- the machine of the invention has a double work station corresponding to the two longitudinal beds of rotating rollers 1, so that the mobile carriage 8 carrying the blade 10-10 'makes a cut on the upper side face of the respective slate block 4, mobile carriage 8 that will alternately travel to both work stations.
- Said necessary closure can also be carried out by means of the pneumatic mattress 12 'replacing the central roller 12 of soft material.
- the tilting supports 3 have lateral portions 15 associated with horizontal guides 16 to control the mobility of said tilting support 3 during its tilting for the turn of the slate blocks 4.
- Each group of vertical rollers 11 is coupled to opposite supports 17 with regulation to adapt to the width of the slate blocks 4.
- the automaton makes an accurate calculation of the measures to which the cuts have to be made (within a predetermined tolerances), in order to cut the entire block into pieces of equal dimensions without leaving the last piece out of measure as rejection. It is understood that the measurements of the pieces of a block to be exfoliated will be equal to the difference of the two blocks distributed by the number of pieces. You can also preset some dimensions, in the anterior and posterior parts of the faces of the block, as an unusable discard due to its irregularities or low value, in which case, the automaton will not consider these two dimensions, preset, as part of the block and will make subdivisions without counting on these discards.
- the machine of the invention incorporates a pneumatic tank with adjustable pressure (not shown in the figures) to feed the pneumatic mattress 12 'of the jaw 11, as well as to blow the pressurized air into the incisions on the block of slate 4 to produce the exfoliate and in general to supply pressurized air to any element or part of the machine that requires it.
