Description

The present invention relates to a bonding apparatus for bonding a long synthetic resin plate forming a kitchen top plate or a washstand.

Conventionally, when using an acrylic synthetic resin plate to form a kitchen top plate or wash basin, long plates that are perpendicular to each other at both ends in the short direction of the substrate made of a long synthetic resin plate are bonded together. And formed.

The work process for bonding the long synthetic resin plate includes a plate material (front plate) that intersects the substrate in the vertical direction on the front side of the substrate placed on the work table, and a rear end at a direction perpendicular to the substrate. The plate materials (back plate) to be installed after being installed are bonded to each other.

As shown in FIG. 13, the adhesive method is such that an adhesive is applied to one end face of a long substrate 70 placed on a work table A, and a front plate formed to the same position as the substrate 70 at the bonding position. After the upper end of the rear surface of 71 is brought into contact, a crimping jig, for example, a first fixing member 77 provided at one end of the shaft portion 76 of the chisel 75 is hooked on the opposite side of the substrate 70, and the shaft A second fixing portion 78 provided at the other end of the portion 76 is hooked on the outside of the front hanging plate 71, and a fastening screw 79 provided on the second fixing portion 78 is rotated to turn the second fixing portion 78 into the first. The substrate 70 and the front plate 71 are bonded and fixed by pressure bonding in the direction of the fixing portion 77 with a predetermined pressure. This work is repeated by repeating at least 15 to 20 hats.

Next, after the adhesive fixing of the front plate 71 is completed, as shown in FIG. 14, an adhesive is applied to the lower surface of the back plate 73 formed to the same length as the substrate 70, and the upper end edge on the back side of the substrate 70. After being positioned, the first fixing portion 82 of the short chisel 80 is hooked to the bottom surface side of the substrate 70, and the second fixing tool 84 provided at the other end of the shaft portion 81 is hooked to the upper end of the back plate 73. Then, the fastening screw 85 is rotated and fixed by crimping. As is well known, this operation is repeated in the same manner as the above-mentioned chisel, and the bonding operation is performed (Patent Document 1).

However, since the front plate 71 is bonded and fixed to the substrate 70 after the front plate 71 is bonded and fixed, the back plate 73 is bonded twice. Moreover, since it takes time until the adhesive is fixed after it is applied, the working efficiency is poor and inefficient. Further, it is troublesome and troublesome to perform a work of attaching and fastening a large number of hats one by one to the substrate.

A synthetic resin plate 1 formed of an acrylic synthetic resin material or the like is often used as a so-called artificial marble plate for a kitchen top plate or a wash counter of a kitchen. When the synthetic resin plate 1 is formed, for example, as a kitchen top plate, the substrate 2 is composed of a front plate 5 and a back plate 8, and the substrate 2 has a long direction of 2700 mm to 3000 mm, a short direction of 700 mm to 800 mm, The front plate 5 that is formed to have a thickness of 10 to 15 mm and is attached to the lower side in the vertical direction on the near side of the substrate, and the back plate 7 that rises in the vertical direction at the rear end of the substrate 2 have the same length and thickness as the substrate 2. The upper and lower widths are formed from 45 mm to 50 mm.

As shown in FIGS. 2 and 3, the bonding apparatus 10 that bonds and assembles the substrate 2, the front plate 5, and the back plate 7 forms a work base 11 with a length and width on which the substrate 2 can be placed, In order to position the front plate 5 to be bonded to the front side of the substrate 2 in the vertical direction, a front support portion 12 is formed in which one side of the work base 11 is formed one step lower, and a large number of the front support portions are arranged in the longitudinal direction of the front support portion. First clamp bases 13 are attached at predetermined intervals, and horizontal clamps 20 for pressing the front plate 5 are respectively installed on the first clamp bases 13. The mounting position of the horizontal clamp 20 is set at a height at which the pressing cylinder 30 of the horizontal clamp 20 comes into contact with the intersecting portion of the front plate 5 bonded to the substrate 2.

The back plate 15 is formed on the opposite side of the work base 11 in the same plane as the work base, and is attached to the back support portion by being vertically raised at the back end portion of the substrate 2. A plurality of second clamp bases 16 that are one step higher in order to press 7 in the vertical direction are attached at predetermined intervals in the longitudinal direction, and vertical clamps 40 that press the back plate 7 in the vertical direction are attached to each second clamp base 16. is there.

As shown in FIGS. 4, 8, and 9, the back support portion 15 serves as a guide for bonding the substrate 2 and the back plate 7 at a right angle with the wall surface of the back plate 7 on the front side of the second clamp base 16. A wall surface receiving portion 19 that is in contact with each other is formed, and a space plate 17 is attached between each second clamp table 16. The end surface of the space plate 17 and the end surface 2a in the short direction of the substrate 2 are brought into contact with each other, and the wall surface 7a of the back plate 7 is brought into contact with the wall surface receiving portion 19 of the second clamp table 16, respectively. And the end face of the substrate 2 can be positioned so as to be flush with each other and at right angles.

Therefore, by setting the depth width of the substrate 2 by bringing the back end surface 2a of the substrate 2 into contact with the end surface of the space plate 17, the end of the substrate 2 protrudes from the end of the work base 11, and the locking step The fitting adhesion between the portion 3 and the fitting recess 6 of the front plate 5 is facilitated. Further, when the back plate 7 is bonded to the substrate 2, a space is formed between the lower end of the back plate 7 and the end surface 2 a of the substrate 2, so that it is possible to easily wipe off the adhesive protruding from the bonded portion. . Moreover, since the casters 18 are attached to the bottom four corners of the work base 11, the work base 11 can be easily moved in the factory.

As shown in FIGS. 5 to 7, the horizontal clamp 20 has a guide cylinder 23 attached to a support portion 22 provided at the tip of a support frame 21, and a link mechanism X is attached to the rear end of a pressing rod 24 inserted into the guide cylinder. The pressure rod 24 is connected and formed so as to be able to move forward and backward by the link mechanism, and a pressure cylinder 30 for pressing the front plate 5 is attached to the tip of the pressure rod so as to be extendable and retractable.

The link mechanism X includes an operation handle 25, a first link 26, and a second link 27. One end of the first link 26 is pivotally supported by the rear end of the support frame 21, and the other end is operated by the operation handle. The second link 27 is pivotally supported at one end of the pressing rod 24 and the other end is pivotally supported at an intermediate portion of the first link 26. When the operation handle 25 is pivoted from the horizontal position in the vertical direction (arrow direction), the pressing rod 24 moves forward, and the front plate 5 is formed so as to be pressed in the direction of the substrate 2 by the pressing cylinder 30 attached to the tip. is there.

The horizontal clamp 20 can move the pressing rod 24 forward and backward with a single touch by simply rotating the operation handle 25 and press the front hanging plate 5 with a predetermined pressure. Since the work of fastening the screws one by one is unnecessary, the work can be performed efficiently.

As shown in FIG. 7, the pressing cylinder 30 attached to the tip of the pressing rod 24 of the horizontal clamp 20 is divided into two from the center, and the screw shaft 28 attached to one of the first cylindrical portions 31 at the tip of the pressing rod 24. Is inserted into the recess 34 of the other second cylindrical portion 33, and the spring 35 is accommodated in the concave portion 34 of the other second cylindrical portion 33. They are bonded to each other and covered with a reinforcing ring 37 on the outer peripheral surface of the bonded portion, and are urged so as to expand and contract in the direction of the pressing rod 24.

Accordingly, when the front end of the pressing cylinder 30 presses the front plate 5, the pressing cylinder 30 moves back and forth on the screw shaft 28 within the expansion / contraction range of the spring 35, thereby generating a uniform pressing force. You can do it. Further, even if pressing unevenness occurs in the horizontal clamp 20, the pressing cylinder 30 can be expanded and contracted to prevent the surface of the front plate 5 from slipping or being damaged.

Furthermore, since the substrate 2, the front plate 5 or the back plate 7 is formed of a synthetic resin material, the thickness of the plate is not uniform and the surface tends to be biased. For this reason, the uneven thickness portion generated in the plate causes a weakening of the adhesive force, and therefore, by providing a cushioning property (extensible and retractable) to the pressing cylinder 30 of each horizontal clamp 20, there are places where the pressing force is strong and weak. Therefore, uneven bonding can be prevented since the pressure can be uniformly pressed and bonded.

In addition, since the kitchen top plate formed of the synthetic resin plate 1 has different plate thicknesses depending on applications, the screw shaft 28 attached to the tip of the pressing rod 24 is rotated when bonding plate materials having different thicknesses. By moving the position of the latching portion 32 back and forth, the position of the pressing cylinder 30 can be adjusted to obtain an appropriate pressing force.

By attaching a flexible pad (not shown) such as a nonwoven fabric to the front end surface of the pressing cylinder 30, the pressing portion 30 prevents the contact portion from slipping or sliding when the front plate is pressed, thereby preventing the surface from being damaged. be able to. Furthermore, it is needless to say that the pressing force can be improved by providing a protrusion (not shown) at the center of the tip surface of the pressing cylinder 30 and pressing it at one point.

As shown in FIGS. 8 to 12, the vertical clamp 40 is positioned on the back side of the substrate 2 by a pressing cylinder 52 and a wall pressing body 65 attached to the movable arm 43 by a link mechanism Y provided above the support frame 41. The back plate 7 is formed so that it can be crimped in the vertical direction.

The link mechanism Y includes an operation handle 42, a movable arm 43, and an operating link 46. One end of the operation handle 42 is pivotally supported below the support frame 41, and the rear end of the movable arm 43 is supported on the support frame. 41 is pivotally supported behind the upper end of 41, and the middle of the movable arm and the middle of the operating handle 42 are pivotally supported by an operating link 46 to connect the operating handle 42 from the horizontal position. When pivoted in the vertical direction (arrow direction), the movable arm 43 is pivoted and lowered, pressing the upper end of the back plate 7 in the vertical direction with the pressing cylinder 52 and simultaneously pressing the wall surface of the back plate 7 with the wall pressing member 65. .

As shown in FIG. 10, the movable arm 43 has a pressing screw shaft 48 and a supporting screw shaft 61 positioned in parallel in a vertical direction inside a parallel arm portion 44 having a U-shaped tip, and the arm portion 44. Are attached to the lower ends of the press screw shaft 48, and a press cylinder 52 is attached to the lower end of the press screw shaft 48. A body 65 is attached.

The pressing screw shaft 48 and the supporting screw shaft 61 attached to the movable arm 43 are formed such that the supporting position can be adjusted in the longitudinal direction of the arm portion 44 by loosely tightening the nuts 50 and 63, respectively. Therefore, the position of the pressing cylinder 52 can be finely adjusted in the vertical direction according to the thickness and length of the back plate 7 to be bonded, and the pressing position of the wall pressing body 65 attached to the support screw shaft 61 can be finely adjusted. Is formed.

As shown in FIG. 11, a pressing cylinder 52 attached to the tip of the pressing screw shaft 48 is divided into two parts from the center, and the tip of the pressing screw shaft 48 is inserted into one first cylinder part 53 and hooked from the inside. The stopper 54 is mounted, the spring 58 is accommodated in the concave portion 57 of the other second cylindrical portion 56, the first and second cylindrical portions 53 and 56 are bonded to each other, and the reinforcing ring 59 is put on the outer peripheral surface of the bonded portion. It is formed to be stretchable by bonding.

Therefore, when the movable arm 43 rotates and presses the upper end of the back plate 7 in the vertical direction by the pressing cylinder 52, it moves forward and backward within the expansion / contraction range of the spring 58, thereby acting as a cushion and providing a uniform pressing force. It can occur, and the surface of the back plate 7 can be prevented from being damaged or slipped due to the bias.

Furthermore, as described above, since the substrate 2 and the back plate 7 are formed of a synthetic resin material, it is difficult to form a uniform plate thickness, and small uneven portions are easily formed on the surface. If there is uneven thickness in the bonded portion, unevenness in the pressing strength is likely to occur, which causes a decrease in the strength of the adhesive force. Thus, by pressing with the pressing cylinder 52 having a resilient force, it is possible to uniformly press and bond without causing strong or weak pressing force.

Similar to the pressing cylinder 30 attached to the horizontal clamp 20, the pressing cylinder 52 has a contact portion when a flexible pad (not shown) such as a nonwoven fabric is attached to the front end surface and the front plate is pressed. It can also prevent the surface from being damaged by slipping or sliding. Furthermore, it is needless to say that the pressing force can be improved by providing a protrusion (not shown) at the center of the front end surface of the pressing cylinder 52 and pressing it at one point.

As shown in FIG. 11, the wall surface pressing body 65 attached to the tip of the support screw shaft 61 rotatably supports a contact roller 66 that presses the wall surface of the back plate 7 on the pressing frame portion 65a attached to the tip. The pressing piece 67 is urged by a leaf spring 68 so as to be pivotable. Therefore, the elastic force of the leaf spring 68 can be uniformly pressed and bonded.

Hereinafter, the operation of the embodiment of the present invention will be described. In the bonding apparatus 10, the first clamp table 13 is arranged at a constant interval on the upper surface of the front support table 12 provided in the longitudinal direction of one side of the work base 11 formed in a long shape. (100 mm to 200 mm) are installed in large numbers, and the second clamp table 16 is installed on the upper surface of the back support 15 provided in the longitudinal direction opposite to the work base 11 at a position symmetrical to the first clamp table 13, respectively. A horizontal clamp 20 that presses the front plate 5 is attached to each first clamp base, and a vertical clamp 40 that presses the back plate 7 is attached to each second clamp base.

For example, when a kitchen top plate is formed by the synthetic resin plate 1, the rear end surface 2 a of the substrate 2 located on the work base 11 of the bonding apparatus 10 is brought into contact with the end surface of the space plate 17 provided on the back support portion 15. As shown in FIG. 5, the front end of the substrate 2 is positioned so as to protrude slightly from the work base 11 by the thickness of the front hanging plate 5. Next, after applying an adhesive to the locking step 3 of the substrate 2, the fitting recess 6 of the front hanging plate 5 is fitted to the locking step 3 and an arbitrary horizontal clamp 20 is operated to temporarily fix it. . By causing the base 2 to protrude from the end of the work base 11 a little more than the thickness of the front slat 5, the wall of the front sill 5 is adhered firmly without hitting the work base 11. Can do.

Further, the back plate 7 with the adhesive applied to the lower end surface is positioned in the vertical direction of the back side end of the substrate 2, and the wall surface 7 a of the back plate 7 is brought into contact with the wall receiving portion 19 of the second clamp table 16. After positioning, the operation handle 42 of an arbitrary vertical clamp 40 is operated and temporarily fixed. After adjusting the position of the front plate 5 and the vertical plate 7 that are temporarily fixed, for example, whether or not they are displaced or distorted, the operation handles 25 and 42 of all other horizontal clamps 20 and vertical clamps 40 are respectively operated. And crimp.

The horizontal clamp 20 is a front hanging plate at the front end surface of the pressing cylinder 30 attached to the front end by advancing the pressing rod 24 by the link mechanism X by one touch only by rotating the operation handle 25 in the vertical direction upward from the horizontal position. 5 can be pressed and bonded to the substrate 2 with a uniform pressure.

The vertical clamp 40 rotates the movable arm 43 by the link mechanism Y and rotates the operation handle 42 in the vertical direction upward from the horizontal position, and presses the back plate 7 with the pressing cylinder 52 attached to the pressing screw shaft 48. At the same time as pressing in the vertical direction, the wall surface of the back plate 7 can be pressed by the abutting roller 66 of the wall surface pressing body 65 attached to the support screw shaft 61 to correct the longitudinal distortion and displacement of the back plate 7.

The pressing cylinders 30 and 52 attached to the horizontal clamp 20 and the vertical clamp 40 press the front plate 5 and the back plate 7 by accommodating the springs 35 and 58 therein and being attached to be movable back and forth in the axial direction. Occasionally, it acts as a cushion, and it is possible to prevent the contact portion from slipping or the surface from being damaged by pressing the pressing cylinders 30 and 52 with a uniform pressing force.

The wall surface pressing body 65 is provided with a contact roller 66 rotatably at the tip of the pressing piece 67, so that the wall surface of the back plate 7 is damaged by smoothly moving the position hitting the wall surface by the pivot of the movable arm 43. Can be prevented.
