Abstract

Provided are a sucking and holding device capable of firmly sucking and holding an object to be conveyed such as a tile with an uneven surface, and a contact body for the sucking and holding device. The sucking and holding device (1) is placed above an arrayed body of tiles (10) and lowered to press the bottom surface of a bag (5) of the contact body (3) against the upper surfaces of the tiles (10). The contact body (3) is formed by placing grains (6) in the bag (5) and is non-elastically deformable. Negative pressure from a negative-pressure source is transmitted to a suction opening (2c) to cause the tiles (10) to be sucked and held at the bottom surface of the bag (5). When the sucking and holding device (1) is lifted, the tiles (10) are separated from an alignment frame (11) while being sucked to the bag (5). Because deformation of the bottom surface of the contact body (3) is non-elastic, the contact body (3) does not elastically recover the original shape and therefore each tile (10) is firmly held by the contact body (3) in a close contact relationship.

Description

Specification

Device that holds the transported object by suction

Field of Invention

[0001] The present invention relates to an abutment 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).

Background of the Invention

A tile unit in which a plurality of tiles are regularly arranged in a planar shape and the tiles are connected to each other by paper or a net is widely used. In addition, tile panels are widely used, where a plurality of tiles are regularly arranged on the base panel in an IJ-aligned state.

[0003] When manufacturing such tile units and tile panels, after arranging a plurality of tiles in an alignment frame to form a regular array, the regular array is placed in a regular array state. Carry it to the next process while keeping it (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 2002-86433 A).

[0004] When the tile surface is rich in irregularities such as crushed stone, air leaks and the suction holding force tends to be insufficient.

[0005] JP-B-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 on a transported object having an uneven surface.

[0006] 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 the hand is moved upward to lift the transported body. When this occurs, the elasticity of the sponge itself restores it to its original flat shape, creating a gap between the sponge and the uneven surface, causing air to leak and the carrier to fall off.

Detailed description

[0012] In the contact body of the present invention and the suction holding device including the contact body, the contact body follows the shape of the outer surface of the transported body when the contact body is brought into contact with the transported body. Deforms inelastically ,In close contact. Since the deformation of the contact body is inelastic, the contact body is prevented from being restored to its original shape even if the suction holding device that moves the transported body is moved (for example, raised). The contact state between the contact body and the transported body is maintained, and the transported body is prevented from falling off.

[0013] When the abutting body is filled with particles in the outer shell, and at least the front portion of the outer shell is constituted by a sheet, and at least a part of the sheet is air permeable, the corresponding contact is obtained. When the body is brought into contact with the transported body, the sheet deforms following the shape of the outer surface of the transported body. At this time, the particles in the outer shell body move in the outer shell body, and the contact body becomes inelastic. Transforms into

[0014] When spherical particles are used as the particles, the contact body is easily deformed. In addition, when hollow particles are arranged with respect to spherical particles, the air permeability of the particle packing body is improved.

[0015] When the outer shell is a bag, the bag can be easily attached to the casing of the suction holding device, and can be detachable.

[0016] A dispersion plate or a rectifying plate is provided between the suction port of the casing and the contact body so that the negative pressure from the suction port is transmitted as evenly as possible to the entire contact body. The suction holding force of the carrier can be equalized on the front surface of the contact body.

Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 is a cross-sectional view of the suction holding device according to the embodiment, FIG. 2 is a perspective view from below of the contact body, FIG. 3 is a perspective view showing an example of particles, and FIGS. 4 to 6 FIG. 4 is a cross-sectional view showing the tile suction holding operation of the tile by this suction holding device.

As shown in FIG. 1, the suction holding device 1 includes a casing 2 that is open downward, a contact body 3 that is attached to the lower surface side of the casing 2, a corresponding contact body 3, and a casing. And a dispersion plate (distributor) 4 disposed between the two ceiling sections 2a.

In this embodiment, the casing 2 has a bottomless lid shape having the square ceiling portion 2a and a skirt portion 2b depending from the peripheral edge of the ceiling portion 2a. 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.

[0020] 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 sides 5s (Fig. 2) of knogg 5 contain synthetic resin. Non-breathable due to immersion. A plurality of ventilation portions 5a are provided on the bottom surface of the bag 5, and a non-venting portion 5b is provided between the ventilation portions 5a. This non-venting part 5b is also formed by impregnating a cloth with a synthetic resin.

[0021] As the base fabric constituting Nog No. 5, for example, a woven fabric of synthetic resin fibers such as polyvinyl chloride vinylidene is suitable. A silicone resin or the like is suitable as the resin for impregnation. However, the material of the bag and the resin for impregnation is not limited to this.

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 has 4 rows. A total of 16 are arranged in 4 rows. However, the number and arrangement of tiles are not limited to those shown in the figure.

[0023] The non-venting parts 5b are extended between the ventilation parts 5a in a grid pattern and are extended along the entire periphery of the bottom surface of the bag 5. The size of each ventilation part 5a is slightly smaller than the tile 10.

[0024] The particles 6 packed in the knot 5 are a mixture of spherical particles, which are preferably spherical, and short hollow cylindrical particles 6a as shown in FIG. Also good. When the bottom surface of the bag 5 filled with spherical particles is pressed against the uneven surface, the bottom surface easily deforms rapidly following the uneven surface. When hollow cylindrical particles are mixed with spherical particles, the airflow resistance in the knot 5 is reduced.

[0025] The particles 6 are filled so that there is a little margin rather than filling the bag 5 tightly (so-called "bread"), and the bottom surface of the contact body 3 is freely deformed following the uneven surface. It is preferable to facilitate this.

[0026] 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 lmm, and a length force of about 10 to 10 mm. When spherical particles and hollow cylindrical particles are mixed, the ratio of hollow cylindrical particles is 50% by volume or less of the total particles (in this case, the volume of hollow cylindrical particles is π · (outer diameter / 2) ² · [long )] Is preferable, and about 20 to 50% by volume is particularly preferable.

[0027] The particle material is preferably a light-weight and durable synthetic resin, such as a melamine resin or an talyl resin, but the resin material is not limited to this.

[0028] The contact body 3 in which the particles 5 are filled with the particles 6 is attached to the dispersion plate 4 by appropriate attachment means. Removably held on the lower side. For example, after fitting the abutment body 3 to the lower side of the dispersion plate 4 in the casing 2, the breathable cloth is drawn to the lower side of the abutment body 3, and the peripheral edge portion of the breathable cloth is connected to the skirt portion 2b. It is possible to adopt a means such as removably fastening to the head.

[0029] The dispersion plate 4 is used to transmit a negative pressure from a 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. It has been. The material is preferably ceramics or metal, but is not limited thereto. A rectifying plate (such as a punching plate) may be provided instead of the porous sintered plate.

[0030] 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. FIG.

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

The suction holding device 1 is disposed above the array of tiles 10 (FIG. 4), and is lowered to press the bottom surface of the bag 5 of the contact body 3 against the top surface of the tile 10. As a result, 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 force near the bottom surface of the particles 6 in 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, and 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, the 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. It should be noted that 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 upper surface of the tile 10, but as described above, in order to eliminate unnecessary consumption of the negative pressure, It is preferable that negative pressure is applied after the bag 5 is in 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 sucked by 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 tile unit manufacturing mesh to which an adhesive is previously applied, the negative pressure transmission is stopped, and the back surface of the tile 10 (the lower surface of the figure is placed on the mesh). ) To adhere.

[0035] In the state where the suction holding device 1 is raised as shown in FIG. Although the deformation of the bottom surface of the contact body 3 is inelastic as described above, the contact body 3 has the original shape. The tiles 10 are held in close contact with the contact body 3 without being elastically restored.

[0036] In the above embodiment, the contact body 3 has the force S that employs the bag 5, and in this way, the bag 5 attached to the case 2 can be easily replaced with another bag. However, in the present invention, an air-permeable sheet 15 is provided so as to cover the bottom of the casing 2 and the particles 6 are filled between the air-permeable sheet 15 and the dispersion plate 4 as in the adsorption holding device 1A of FIG. You can do it.

[0037] In each of the above embodiments, the dispersion plate 4 is provided. However, in the case of using the tapered casing 20 that expands downward as in the suction holding device 1B of Fig. 8, the dispersion plate is provided. Even without this, the negative pressure can be transmitted substantially evenly to the entire bottom surface of the suction holding device 1B. The casing 20 in 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 particles 6 are filled between the breathable sheet 15 and the net 22.

[0038] 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 portion 5a is also arranged in a square lattice. It is not limited.

[0039] For example, when rectangular tiles are arranged in a staggered manner with the left and right positions being alternately shifted as shown in Fig. 10a, the ventilation portion 41 is arranged like the contact body 40 in Fig. 10b. Provide the same arrangement as tile 30. 10a is a plan view of the array of tiles 30 and FIG. 10b is a bottom view of the contact body 40.

[0040] Even when the tile arrangement is other than that in Fig. 10a, similarly, the tile can be adsorbed and retained by matching the arrangement of the ventilation portions with the arrangement of the tiles' J.

[0041] In the above description, tiles are sucked and held, but transported objects other than tiles may be sucked and held.

[0042] 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 is brought into contact with the side surface of the transported body from the lateral direction. May be. further After sucking and holding the tile, the suction holding device may be rotated so that the back surface of the tile is pressed against the wall surface.

Although the present invention has been described in detail using specific embodiments, it will be apparent to those skilled in the art that various modifications can be made without departing from the spirit and scope of the invention.

This application is based on a Japanese patent application filed on May 31, 2005 (Japanese Patent Application No. 2005-1 59680), which is incorporated by reference in its entirety.
