Fig. 2 represents the plane graph of grinding unit 4.But in fig. 2, eliminate the gripper shoe as upper price fixing, represent the form of the lamination rubber unit 12 being configured with air spring 10 and composition rotary transfer machine on abrasive sheet 7.
As in figure 2 it is shown, on the abrasive sheet 7 of rectangle, be configured to string along its long side direction, air spring 10 and lamination rubber unit 12.And, abrasive sheet 7 is when keeping this attitude (its direction laterally long in the drawings configure), point beyond the mass centre of abrasive sheet 7 rotates (revolution), but in order to this torque is delivered to abrasive sheet 7, lamination rubber unit 12 configures towards two directions of vertical and horizontal.
Fig. 3 represents the sectional view of the grinding unit 4 along the 3A-3A line in Fig. 2.But in figure 3, also show the gripper shoe 6 eliminated in fig. 2.
As shown in Figure 3, grinding unit 4 configures air spring 10 and lamination rubber unit 12 between gripper shoe 6 and abrasive sheet 7, pushing force (grinding pressure) P1, P2 during abrading glass plate 3 is applied to abrasive sheet 7 by air spring 10, and the rotation driving torque carrying out self-supporting slab 6 is delivered to abrasive sheet 7 by lamination rubber unit 12.Air spring is the elastic fluid spring that make use of air, has the effect absorbing vibration.Additionally, be used as make use of the fluid spring of the gas beyond air.
Further, the lower surface (glass plate 3 side) at abrasive sheet 7 such as installs the grinding pad of foamed polyurethane, by the surface (machined surface) of this grinding pad 8 abrading glass plate 3 (omitting diagram at this).
Make the grinding unit 4,4 of so composition ... eccentric rotary (revolution) respectively, under it, on abrasive disk 2, transfer glass plate 3, so that glass plate 3 is by each grinding unit 4,4 ... continuously grinding.

Additionally, except the mode of central shaft 16 and another pin 17 is set, it is possible to two pins are set except central shaft 16.So, lamination rubber components does not rotate, and can prevent the abrasion of end face.
In the example of the grinding unit 4 shown in Fig. 2 described above, there are two air springs 10 and three lamination rubber units 12, Fig. 6 represent the example of bigger grinding unit 4.
Example shown in Fig. 6 all configures air spring 10 and lamination rubber unit 12 on the abrasive sheet 7 of the rectangle of grinding unit 4.Represent air spring 10 with circle all in the drawings, represent lamination rubber unit 12 with rectangle.
Example shown in Fig. 6 (A) has three air springs 10 and four lamination rubber units 12.In the example shown in Fig. 6 (B), abrasive sheet 7 is bigger, has seven air springs 10 and four lamination rubber units 12.Further, in the example shown in Fig. 6 (C), abrasive sheet 7 becomes greatly further, has ten air springs 10 and eight lamination rubber units.
Therefore, in the present embodiment, by using multiple lamination rubber unit, can corresponding various bigger lapping devices (grinding unit).Further, in each lamination rubber unit in 12, pressurize to small-sized lamination rubber, and prevent it around the rotation of central shaft, therefore can improve the durability of grinding unit.
The example of lapping device described above employs the abrasive sheet of rectangle, and following description employs the example of the abrasive sheet of circle.
Fig. 7 represents that the summary of the abrasive wire with grinding unit is constituted, and above-mentioned grinding unit has the abrasive sheet of circle.
As it is shown in fig. 7, the abrasive wire 1 shown in this abrasive wire 100 and Fig. 1 is similarly, it is made up of following: abrasive disk 2, is equipped with glass plate 3, transfer to the transfer direction shown in arrow A direction；Grinding unit 104 (only showing one in Fig. 7) ..., on abrasive disk 2 above the glass plate 3 of transfer, multiple along transfer direction A configuration.
Wherein, grinding unit 104 has gripper shoe and abrasive sheet (omitting diagram) wherein, is configured with eccentric rotary mechanism 106 at an upper portion thereof.Eccentric rotary mechanism 106 makes abrasive sheet rotate (rotation) as shown by arrow B around its central shaft by the gripper shoe in grinding unit 104, and around rotating (eccentric rotary, so-called revolution) shown in the point such as dotted line of the central shaft of deviation abrasive sheet and arrow C while making abrasive sheet rotation.Further, though the diagram of eliminating, but grinding pad is set at the lower surface of abrasive sheet.
And, though the diagram of eliminating, but identical with shown in Fig. 3, between gripper shoe and the abrasive sheet in this grinding unit 104, it is also provided with multiple air spring that grinding pressure is provided from gripper shoe to abrasive sheet and for rotation driving torque being delivered to the lamination rubber unit of abrasive sheet.Further, the plurality of air spring, between gripper shoe and abrasive sheet, is arranged on the position that the pushing force to glass plate becomes impartial.
The grinding unit 104 so constituted is configured multiple along abrasive wire 100, makes abrasive sheet rotation and the revolution respectively of each grinding unit 104, on grinding table 2, thereunder transfer glass plate 3, thus continuously grinding glass plate 3.
Fig. 8 represents an example of the arrangement of the air spring between the gripper shoe and abrasive sheet being arranged in grinding unit 104 and lamination rubber unit.
As shown in Figure 8, on abrasive sheet 107, eight air springs 110 and four lamination rubber units 120 are arranged respectively on uniform position on circular abrasive sheet 107.
Further, Fig. 9 represents the example configuring air spring 110 and lamination rubber unit 120 on the abrasive sheet 107 when making grinding unit 104 in more large-scale.
In the example shown in Fig. 9,16 air springs 110 and four lamination rubber units 120 are arranged on uniform position on abrasive sheet 107.
Further, when so making grinding unit 104 maximize, from gripper shoe to abrasive sheet, the lamination rubber unit 120 of transmission rotation driving torque also must transmit big torque, and the number therefore increasing lamination rubber carries out correspondence.
Figure 10 represents an example of lamination rubber unit 120 now.
Lamination rubber unit 120 is made up of following: the dimetric basket 122 being combined with abrasive sheet 107；The installation portion 124 combined with gripper shoe (omitting diagram) and lamination rubber components 126.
