Description

  The present invention relates to an abutting body and a suction holding device used for the purpose of sucking and holding a transported object such as a tile and transporting (for example, transferring).

  A tile unit in which a plurality of tiles are regularly arranged in a plane and the tiles are connected to each other by paper or a net is widely used. In addition, a tile panel in which a plurality of tiles are pasted in a regularly aligned state on a base panel is also widely used.

  When manufacturing such a tile unit or tile panel, a plurality of tiles are arranged in an alignment frame to form a regular array, and the regular array is maintained in a regular array state. Transport to the next process (referred to as “transfer”). In order to perform this tile transfer, a transfer machine having a suction cup and a negative pressure source is used (for example, JP-A-2002-86433).

  In such a suction cup, when the tile surface is rich in irregularities such as crushed stone, air leaks and the suction holding force tends to be insufficient.

  Japanese Utility Model Publication No. 7-4140 describes that a sponge is provided on the front surface of a hand so as to be sucked and held by a vacuum suction hand even if the surface is uneven.

However, when this sponge is pressed against the uneven surface of the transported body, it deforms following the uneven surface of the transported body due to the pressing force, but then when the hand is moved upward to lift the transported body, The elasticity of the sponge itself restores the original flat shape, and a gap is generated between the sponge and the uneven surface, causing air to leak and dropping the transported object.

A suction port 2c is provided at the center of the ceiling 2a, and is connected to a negative pressure source such as a vacuum pump via a hose or the like.

  The contact body 3 includes a bag 5 as a rectangular parallelepiped outer shell approximate to a flat plate, and particles 6 filled in the bag 5. The bag 5 is mainly made of a breathable cloth, and its upper surface is breathable as a whole. The four side surfaces 5s (FIG. 2) of the bag 5 are impermeable due to impregnation with synthetic resin or the like. A plurality of ventilation portions 5a are provided on the bottom surface of the bag 5, and the ventilation portions 5a are non-venting portions 5b.

  The suction holding device 1 according to this embodiment is for holding 16 tiles 10 arranged in 4 rows and 4 columns as shown in FIG. 9, and the ventilation portion 5a is arranged in 4 rows and 4 columns. A total of 16 are provided. However, the number and arrangement of tiles are not limited to those shown in the figure.

  The non-venting part 5b extends between the ventilation parts 5a in a grid pattern and extends along the entire periphery of the bottom surface of the bag 5. The size of each ventilation part 5 a is slightly smaller than the tile 10.

  As the base fabric constituting the bag 5, for example, a woven fabric such as polyvinylidene chloride is suitable. As the resin for impregnation for constituting the non-venting part, a silicone resin or the like is suitable. However, the material of the bag and the resin for impregnation is not limited to this.

  The particles 6 filled in the bag 5 are preferably spherical, but may be a mixture of spherical particles and short hollow cylindrical particles 6a as shown in FIG. When the bottom surface of the bag 5 filled with spherical particles is pressed against the concavo-convex surface, the bottom surface easily deforms rapidly following the concavo-convex surface. When hollow cylindrical particles are mixed with spherical particles, the airflow resistance in the bag 5 is reduced.

  The particles 6 are not filled in the bag 5 tightly (so-called “bread and bread”), but are filled so that there is a margin, and the bottom surface of the contact body 3 is easily deformed freely following the uneven surface. It is preferable to do so.

The particle size of the spherical particles is preferably about 0.5 to 3 mm. The hollow cylindrical particles preferably have an outer diameter of 3 to 7 mm, a thickness of the cylindrical portion of 0.2 to 1 mm, and a length of about 5 to 10 mm. When spherical particles and hollow cylindrical particles are mixed, the ratio of the hollow cylindrical particles is 50% by volume or less of the whole particles (in this case, the volume of the hollow cylindrical particles is (outer diameter / 2) ² × length To be calculated) is preferable, and about 20 to 50% by volume is particularly preferable.

  The material of the particles is preferably a synthetic resin that is lightweight and has good durability, such as a melamine resin or an acrylic resin, but the resin material is not limited to this.

  The contact body 3 formed by filling the bag 5 with the particles 6 is detachably held on the lower side of the dispersion plate 4 by appropriate attachment means. For example, after the contact body 3 is fitted to the lower side of the dispersion plate 4 in the casing 2, the breathable cloth is drawn to the lower side of the contact body 3, and the peripheral portion of the breathable cloth is set to the skirt portion 2 b. It is possible to adopt a means such as removably fastening to the head.

  The dispersion plate 4 is used to transmit the negative pressure from the negative pressure source to the upper surface of the bag 5 substantially evenly. In this embodiment, a porous sintered plate having continuous pores is used. . The material is preferably ceramics or metal, but is not limited thereto. A rectifying plate (for example, a punching plate) may be provided instead of the porous sintered plate.

  A method of holding the tile 10 using the suction holding device 1 configured as described above will be described with reference to FIGS. 4 to 6.

  The tiles 10 are arranged in 4 rows and 4 columns on the tile alignment frame 11. The upper surface (front surface of the tile) of the tile 10 is a design surface rich in unevenness.

  The suction holding device 1 is disposed above the array of tiles 10 (FIG. 4) and lowered to press the bottom surface of the bag 5 of the contact body 3 against the top surface of the tiles 10. Thereby, as shown in FIG. 5, the bottom surface of the bag 5 is deformed following the irregularities on the top surface of the tile 10 and is in close contact with the top surface of the tile 10. This deformation is caused by the particles 6 in the bag 5 near the bottom surface of the bag 5 being pushed by the convex portion on the top surface of the tile and moving toward the concave portion on the top surface of the tile, which is an inelastic deformation. .

  In this way, after the bottom surface of the bag 5 is brought into close contact with the top surface of the tile 10, negative pressure from the negative pressure source is transmitted to the suction port 2 c, and the tile 10 is attracted and held on the bottom surface of the bag 5. The transmission of the negative pressure may be started at a stage before the bottom surface of the bag 5 comes into close contact with the top surface of the tile 10, but in order to eliminate wasteful consumption of the negative pressure, the bag 5 as described above. It is preferable that the negative pressure is applied after the material is brought into close contact with the tile 10.

  Next, when the suction holding device 1 is raised as shown in FIG. 6, the tile 10 is pulled away from the alignment frame 11 while being attracted to the bag 5. In this way, the tile 10 is sucked and held and sent to the next process. For example, the tile 10 held as shown in FIG. 6 is lowered onto a mesh for manufacturing a tile unit to which an adhesive is previously applied, the transmission of negative pressure is stopped, and the back surface of the tile 10 (the lower surface in the figure) is stopped. ) To adhere.

  In the state where the suction holding device 1 is lifted as shown in FIG. 6, the bottom surface of the contact body 3 is deformed into irregularities following the irregular surface of the tile 10, but as described above, the contact body Since the deformation of the bottom surface of 3 is inelastic, the contact body 3 does not attempt to restore its original shape elastically, and each tile 10 is in close contact with the contact body 3 and firmly held. The

  In the above-described embodiment, the abutment body 3 employs the bag 5. However, in this way, the bag 5 attached to the casing 2 can be easily replaced with another bag. However, in the present invention, a breathable sheet 15 is provided so as to cover the bottom of the casing 2 and the particles 6 are filled between the breathable sheet 15 and the dispersion plate 4 as in the adsorption holding device 1A of FIG. May be.

  In each of the above embodiments, the dispersion plate 4 is provided. However, when the tapered casing 20 that expands downward is used as in the suction holding device 1B of FIG. 8, the dispersion plate is not provided. The negative pressure can be transmitted substantially evenly to the entire bottom surface of the suction holding device 1B. The casing 20 of FIG. 8 has a suction port 21 at the top, and a particle outflow prevention net 22 is provided so as to cross the suction port 21. A breathable sheet 15 is stretched so as to cover the bottom surface of the casing 20, and the particles 6 are filled between the breathable sheet 15 and the net 22.

  In the above embodiment, as shown in FIG. 9, in order to attract and hold the tiles 10 arranged in a square lattice, the ventilation portions 5a are also arranged in a square lattice, but the present invention is not limited to this. It is not something.

  For example, when rectangular tiles are arranged in a zigzag pattern with the left and right positions being alternately shifted as shown in FIG. 10 (a), the ventilation portion 41 is arranged like the contact body 40 in FIG. 10 (b). Provided in the same array as the tiles 30. FIG. 10A is a plan view of the array of tiles 30, and FIG. 10B is a bottom view of the contact body 40.

  Even when the tile arrangement is other than that in FIG. 10 (a), the tile can be firmly adsorbed and held by matching the arrangement of the ventilation portions with the tile arrangement.

  In the above description, tiles are sucked and held, but transported objects other than tiles may be sucked and held.

  In the above description, the contact body is brought into contact with the upper surface of the tile as the transported body from above, but the contact body may be brought into contact with the side surface of the transported body from the lateral direction. Further, after the tile is sucked and held, the suction holding device may be rotated so that the back surface of the tile is pressed against the wall surface.
