The clamp pad 321 includes an elastic layer made of an elastic material (neoprene rubber, neoprene sponge, etc.) on the front surface side (Z plus side), and the cylinder rod of the clamp cylinder 322 moves in a direction perpendicular to the front surface. It is fixed at the tip.

  The rear clamp 320 is arranged so that the front surface of the clamp pad 321 is parallel to the support frame 210, and the clamp pad 321 can be moved in the front-rear direction orthogonal to the support frame 210 by driving the clamp cylinder 332. Yes.

The clamp base 330 is a prismatic member substantially corresponding to the lifting frame 310 and is attached to the lifting frame 310 via a pair of drive cylinders 331.
The drive cylinder 331 supports the clamp base 330 at the tip of the cylinder rod in the vicinity of both ends of the elevating frame 310.
The clamp base 330 is actuated by the drive cylinder 331 to be adjacent to the upper side of the elevating frame 310 (shown by a solid line in FIG. 1 and indicated by a two-dot chain line in FIG. 5A) and a predetermined height. Can be moved up and down (represented by a two-dot chain line in FIG. 1 and indicated by a solid line in FIG. 5A).

The clamp base 330 is provided with a front clamp 340 and a front support roll mechanism 350.

Arranged and made.
The support pad 341 is fixed to the tip of the long side of the support fitting 342 so that the support surface thereof is parallel to the front surface of the support frame 210.

When the clamp base 330 indicated by a two-dot chain line in FIG. 5A is in the operating position, the support pad 341 of the front clamp 340 faces the clamp pad 321 of the rear clamp 320.
When the clamp base 330 indicated by a two-dot chain line in FIG. 5A is in the retracted position, the support pad 341 does not interfere with the glass block 2 (not shown in FIG. 5 and shown in FIG. 1) on the front side. It is located above (Z plus side) (that is, the support pad 341 is above the upper edge of the glass block 2).

  The front support roll mechanism 350 includes a swing operation arm 351, a pressing roller 352 (support roller), and a swing operation cylinder 353 that swings the swing operation arm 351. A pair is arranged between the pads 341.

The swing operation arm 351 swings in a plane parallel to the YZ plane by a fulcrum shaft 354 provided between the left and right support brackets 342 of the rear surface side (Z minus side) clamp 340 in parallel with the X axis. Supported as possible.
The pressing roller 352 is formed in a disk shape by urethane rubber or the like, and is provided at the lower end of the swing operation arm 351 so as to be rotatable about an axis parallel to the X axis.
The swing operation cylinder 353 has a rear end pivotally supported by the clamp base 330 so as to be swingable in a plane parallel to the YZ plane. The tip of the cylinder rod is connected to the tip of the swing operation arm 351. ing.

  Then, the swing operation arm 351 swings by driving the swing operation cylinder 353, and the pressing roller 352 at the tip thereof moves back and forth. As shown in FIG. 5A, the pressing roller 352 does not protrude rearward (Z minus side) from the plane including the surface of the support pad 341 in the front clamp 340 when the swing operation cylinder 353 is contracted. As shown in FIG. 5 (b), the cylinder rod is extended by driving the swing operation cylinder 353 so as to protrude a predetermined amount (indicated by x2 in the figure) to the rear side (Z minus side) from the plane including the surface of the support pad 341. Is set to

  The holding mechanism 300 configured as described above is configured such that the rotation operation handle 219 is rotated (rotation of the moving drive screw 218), and is moved up and down in the support frame 210 of the lifting frame 310, so that glass blocks of different sizes can be obtained. 2 can be accommodated.

In the holding mechanism 300, the position of the glass block 2 supported by the receiving bar 215 in the front-rear direction with respect to the support frame 210 is defined by the holding position detection roll 231, and the front side (Z plus) is supported by the support pad 341 of the front clamp 340. The rear surface side (Z minus side) is supported by the clamp pad 321 moved by driving the rear surface clamp 320. Thereby, the glass block 2 can be hold | maintained stably.
Since the glass block 2 is mainly supported by the receiving bar 215, the holding by the front clamp 340 and the rear clamp 320 may be supported lightly.

  When the glass block 2 is supported by the receiving bar 215, the front side (Z plus side) is opened by driving the drive cylinder 331 with the clamp base 330 as the retracted position. Then, after the glass block 2 is supported by the support frame 210, the clamp base 330 is set to the operating position by driving the drive cylinder 331, and the above-described holding state is obtained.

  As will be described in detail later, when the glass block 2 held by the holding mechanism 300 is transferred to the pallet, the glass contact roller 216 provided at the tip of the receiving bar 215 (the glass block held as described above). 2 that protrudes to the front side (Z plus side) from 2) glass block or pallet receiving part (floor crossing) already placed on the pallet a predetermined amount above the placement position (pallet floor crosspiece) The glass block 2 is supported by the floor bar of the pallet.

  As described above, the glass contact roller 216 contacts the glass block already placed on the pallet or the receiving portion of the pallet, and the glass block 2 to be held does not directly contact. Damage due to can be suppressed. When the glass contact roller 216 is moved downward and placed on the pallet floor rail, the glass contact roller 216 rolls against the surface (glass block or pallet receiving portion) with which the glass contact roller 216 is in contact. Therefore, it is possible to prevent damage due to rubbing between the glass block 2 being held and the glass block already placed.

  Here, it can be confirmed from the detection signal from the position detection mechanism 240 that the glass contact rollers 216 of the left and right receiving rails 215 correspond to (contact) the mounting positions evenly. That is, if the detection signals are output simultaneously from the left and right unit units in the position detection mechanism 240, it can be seen that the glass contact rollers 216 of the left and right receiving bars 215 correspond (contact) to the mounting position evenly. .

  Then, after the glass block 2 to be held is supported on the floor rail of the pallet, the holding of the glass block 2 by the clamp pad 321 is released by the driving of opening the rear clamp 320, and the swinging operation in the front support roll mechanism 350 is performed. The cylinder 353 is driven to cause the pressing roller 352 to protrude rearward (Z minus side) from the surface of the support pad 341 in the front clamp 340.

  Thereby, the pressing roller 352 of the front support roll mechanism 350 supports the front surface 2 a of the glass block 2 in place of the support pad 341 in the front clamp 340. In this state, the clamp base 330 is moved to the retracted position by the drive cylinder 331. During the movement, the pressing roller 352 of the front support roll mechanism 350 rolls on the front surface 2a of the glass block 2, and the support pad 341 does not slide. Therefore, the support pad 341 does not scratch the front surface 2 a of the glass block 2.

Next, the operation of the holding process of the glass block 2 and the placing process on the pallet which is the transfer table in the transfer apparatus 1 configured as described above will be described with reference to FIGS. 6 and 7.
FIG. 6 is an explanatory diagram of a process in which the transfer apparatus 1 receives and holds the glass block 2 from the cutting line of the plate glass. FIG. 7 is an explanatory diagram of a process of placing (transferring) the glass block 2 to be held on the pallet.

[Operation of Transfer Device 1 in Holding Step of Glass Block 2]
As shown in FIGS. 6A to 6E, the transfer device 1 holds the glass block 2 in which a plurality of glass sheets are stacked from the overturning machine 40 arranged at the discharge position of the cutting line 4.
The overturning machine 40 has a horizontal rotation drive shaft 42 orthogonal to the glass block conveying direction, which supports the glass plate table 41 that supports the lower surface 2c of the glass block 2 and the end surface on the front side in the conveying direction at the discharge position from the cutting line 4. To be able to swing. The overturning machine 40 starts up the glass plate table 41 in a state of being inclined at a predetermined angle (for example, θ = 8.4 °) with respect to the transport direction while supporting the glass block 2.

  When viewed from the side in the horizontal state, the glass plate table 41 overlaps with the roller conveyor 4C in a work conveying direction of the cutting line 4 (with a length capable of supporting the glass block 2) and is viewed in plan. A comb-shaped arm that does not interfere with the roller conveyor 4C of the cutting line 4 is formed.

First, as shown in FIG. 6A, the glass block 2 is held by the transfer device 1 at an angle corresponding to the glass block 2 supported by the inversion machine 40 with respect to the glass support mechanism 20 in the transfer device 1. (That is, an angle corresponding to the glass plate placing table 41) and approaching the glass block 2 supported by the overturning machine 40 (glass plate placing table 41) with the clamp base 330 in the retracted position by driving the drive cylinder 331. Let
At this time, the receiving bar 215 is set to a position below the lower end of the glass block 2 by a predetermined amount. It is assumed that a slit or the like into which the receiving bar 215 can be loosely fitted is formed at a portion of the turner 40 that supports the lower end of the glass block 2 of the glass plate table 41.

  Then, the holding position detection roll 231 in the position defining mechanism 230 is brought into contact with the rear surface 2 b of the glass block 2. When the holding position detection roll 231 comes into contact with the surface of the glass block 2, it is understood that the sensor of the position defining mechanism 230 reacts and thereby the transfer device 1 has a predetermined positional relationship with the glass block 2. Here, the holding position detection rolls 231 (position defining mechanism 230) are arranged in two sets on the left and right, and when only one of them is in contact with the surface of the glass block 2, the transfer device 1 falls over. Since it is inclined in the front-rear direction when viewed from the plane side with respect to the machine 40, adjustment is made so that the transfer device 1 is parallel to the overturning machine 40.

  After confirming that the left and right holding position detection rolls 231 are in contact with the surface of the glass block 2 from the outputs of the sensors of the left and right position defining mechanisms 230, as shown in FIG. Lower. Thereby, the support pad 341 of the front surface clamp 340 faces the front surface 2a of the glass block 2.

  Next, as shown in FIG. 6C, after the transfer device 1 is raised and the receiving bar 215 is brought into contact with the lower end of the glass block 2, the rear surface clamp 320 is driven to drive the clamp pad 321 and the front surface clamp. The glass block 2 is sandwiched between 340 support pads 341. Thereby, the transfer apparatus 1 (holding mechanism 300) holds the glass block 2. As described above, since the glass block 2 is mainly supported by the receiving bar 215, the holding by the rear clamp 320 and the front clamp 340 should be lightly supported.

Thereafter, as shown in FIG. 6D, the angle of the glass support mechanism 20 in the transfer apparatus 1 is changed to an angle (for example, θ = 11.5 °) corresponding to the transfer destination pallet. This change in angle can be set in advance in the control device in the control box 13 and can be automated by operating a button.
Then, a balancer (not shown) is operated to support the weights of the transfer device 1 and the glass block 2, and as shown in FIG. Is lifted from the overturning machine 40 and is moved to the transfer destination (pallet).

[Placement step of glass block 2 on pallet 5 by transfer device 1]
As shown in FIGS. 7A to 7E, the transfer device 1 places the held glass block 2 on the pallet 5.
The pallet 5 includes a gantry 51 having a back plate 53, a floor bar (floor bar) 52 laid thereon, and a receiving portion 54 orthogonal to the floor bar 52.

  The glass block 2 is placed on the pallet 5 by the transfer device 1, first, as shown in FIG. 7A, the angle of the holding mechanism 300 in the transfer device 1 is set to the inclination of the pallet 5 (receiving portion 54). (The angle setting is performed when the glass block 2 is taken out from the above-described overturning machine 40), the transfer device 1 is brought close to the pallet 5, and the receiving bar 215 (glass contact roller) 216) is a position above the floor bar 52 of the pallet 5 by a predetermined amount, and the mounted glass block 6 on which the glass contact roller 216 at the tip of the receiving bar 215 is already mounted on the pallet 5 (the mounted glass block 6 is When it is not placed, it is brought into contact with the lower end of the receiving portion 54).

At this time, the glass plate detection roller 243 of the position detection mechanism 240 comes into contact with the surface of the glass block 2 and a detection signal is output from the detection unit 244, so that the transfer device 1 is already placed on the pallet 5. It can be seen that a predetermined positional relationship with the already mounted glass block 6 (or the receiving portion 54 of the pallet 5) is obtained.
The position detection mechanisms 240 are arranged in two sets on the left and right, and only one of them is in contact with the surface of the mounted glass block 6 (or the receiving portion 54 of the pallet 5) that is already mounted on the pallet 5. In this case, since the transfer device 1 is inclined in the front-rear direction when viewed from the plane direction with respect to the pallet 5, the transfer device 1 is adjusted to be parallel to the pallet 5.
In this state, the lower edge of the lower end of the glass block 2 is in contact with the already-mounted glass block 6 (or the receiving portion 54 of the pallet 5) already placed on the pallet 5.

  Next, as shown in FIG. 7B, the transfer device 1 is lowered until the lower edge of the held glass block 2 comes into contact with the floor rail 52 of the pallet. Note that the floor rail 52 of the pallet 5 is formed with a slit or the like into which the receiving rail 215 (glass contact roller 216) can be loosely fitted.

When the transfer device 1 is lowered, the glass contact roller 216 at the tip of the receiving bar 215 comes into contact with the already-mounted glass block 6 (or the receiving portion 54) already placed on the pallet 5 and rolls. To do. Thereby, the damage by the glass block 2 and the mounted glass block 6 (or receiving part 54) already mounted on the pallet 5 in contact and rubbing can be prevented.
When the glass block 2 comes into contact with the floor bar, the balancer (not shown) is turned off and the glass block 2 is completely supported by the floor bar 52. Then, the rear surface clamp 320 is reversely driven to retract the clamp pad 321 to the rear surface side (Z minus side), and the holding of the glass block 2 with the support pad 341 of the front surface clamp 340 is released.

  After that, as shown in FIG. 7C, the swing operation cylinder 353 in the front support roll mechanism 350 is driven, and the pressing roller 352 is moved to the rear side (Z minus side) from the surface of the support pad 341 of the front clamp 340. Make it protrude. Thereby, the pressing roller 352 supports the front surface 2 a of the glass block 2 in place of the support pad 341.

Thereafter, as shown in FIG. 7D, the clamp base 330 is raised to the retracted position, and the support pad 341 and the front support roll mechanism 350 are moved out of the front surface 2 a area of the glass block 2.
At the time of retraction, the rear surface of the support pad 341 is not in contact with the front surface 2a of the glass block 2, and the pressing roller 352 in the front support roll mechanism 350 rolls on the front surface 2a of the glass block 2. For this reason, the surface of the glass block 2 is not damaged.

By retracting the support pad 341 and the front support roll mechanism 350, the glass block 2 is already placed on the pallet 5, as shown in FIG. ) Toward the front side, and the placement on the pallet 5 is completed.
Then, the pressing roller 352 of the front support roll mechanism 350 is returned to the front side (Z plus side) from the surface of the support pad 341 of the front clamp 340, and the inclination angle of the glass support mechanism unit 20 is maintained when the glass block 2 is held. An angle (that is, an angle corresponding to the glass block 2 supported by the above-described overturning machine 40) is used.
Thus, the holding | maintenance from the inversion machine 40 of the cutting line 4 of the next glass block, and the mounting to the pallet 5 are repeated.

As described above, this embodiment has the following effects.
(1) The transfer device 1 includes a glass contact roller 216 at the tip of a receiving bar 215 that supports the lower edge of the glass block 2. When the held glass block 2 is transferred to a pallet, The abutting roller 216 is brought into contact with a glass block (or a receiving portion of the pallet) already placed on the pallet at a predetermined amount above the floor pallet of the pallet as the placement position, and then moved downward. The glass block 2 is supported on the floor pallet of the pallet.
As a result, the glass contact roller 216 contacts the glass block already placed on the pallet or the pallet transport table, and the glass block 2 to be held does not contact directly. Breakage such as chipping can be suppressed.
When the glass contact roller 216 is moved downward and placed on the pallet floor rail, the glass contact roller 216 rolls against the surface (glass block or pallet receiving portion) with which the glass contact roller 216 is in contact. Therefore, it is possible to prevent damage due to rubbing between the glass block 2 being held and the glass block already placed.

(2) The transfer device 1 includes a pressing roller 352 that can protrude from the surface of the support pad 341 in the front clamp 340. When the front clamp 340 is moved to the retracted position, the pressing roller 352 is moved to the front clamp 340. The front surface 2a of the glass block 2 is supported by the pressing roller 352 by projecting from the surface of the support pad 341 to the rear surface side (Z minus side).
Thereby, when moving the front surface clamp 340 to the retracted position, the pressing roller 352 of the front support roll mechanism 350 rolls on the front surface 2a of the glass block 2. Since the support pad 341 does not slide on the front surface 2a of the glass block 2, the front surface 2a of the glass block 2 is not damaged.

(Deformation)
The present invention is not limited to the above-described embodiment, and various modifications and changes as described below are possible, and these are also within the scope of the present invention.
The present embodiment includes the front support roll mechanism 350 that supports the front surface 2a of the glass block 2 with the pressing roller 352 when the support pad 341 is retracted in the front clamp 340. However, the front support roll mechanism 350 is indispensable. However, it can be omitted if it can be suppressed by applying powder or the like to the surface of the glass block. According to this, the cost can be reduced by simplifying the configuration and shortening the number of process steps.

  In addition, although embodiment and a deformation | transformation form can also be used in combination as appropriate, detailed description is abbreviate | omitted. Further, the present invention is not limited to the embodiment described above.
