Can be stopped. In a state before the ceiling plate 2 enters, the backing bonding device 34 is used.
Is in a standby state. That is, as shown in FIG. 7, the piston of the second air cylinder 56 is in a shortened state, the first beam 42 is stationary in an up state, and the first air cylinder 4
The piston rod 50 of No. 8 is in an extended state. Therefore, the clamp means 40 is in the open state at the clamp standby position shown in FIG.

When the second detecting means detects that the ceiling plate 2 has stopped at the predetermined position by the stopper 38, the clamping means 40 at the position shown in FIG. It descends vertically from the standby position to the clamp position in FIG. When the fifth detecting means detects that the clamping means 40 has been lowered to the clamping position, the piston rod 50 of the first air cylinder 48 starts a shortening operation, and the clamping operation by the clamping means 40 is started. Is gripped.
When the completion of gripping of the backing 6 is detected by the third detecting means,
The shortening operation of the second air cylinder 56 is started, and the clamp means 40 is pulled up from the position in FIG. 8 to the virtual position in FIG. The fifth air cylinder 5
When the completion of the shortening of 6 is detected, the rotary actuator rotates 180 ° clockwise, and the female backing 6 reaches the transfer standby position shown by the solid line in FIG. Ura 6 at this position
Is in a state where the glue application surface is down. Next, the second air cylinder 56 starts the extension operation again, and accordingly, the female backing 6 rises vertically toward the electromagnet 66 at the delivery position. When the extension operation of the second air cylinder 56 is completed, energization of the electromagnet 66 is started, and the backing 6 is attracted by the electromagnet 66.

After the energization of the electromagnet 66 is started, the extension operation of the first air cylinder 48 is started, and the release operation of the clamp means 40 is started, and the shortening operation of the second air cylinder 56 is started. After returning to the delivery standby position, the clamp means 40 rotates the rotary actuator 180 °.

Along with this, the female backing 6 and the electromagnet 66 are lowered to the positions 6 'and 66' in FIG. Along with this lowering operation, the magnet holder 58 strongly presses the adhesive surface of the female backing 6 against the surface of the ceiling plate 2 by a spring force, and when a predetermined pressing force is detected by the pressure-sensitive sensor, the fourth air cylinder 78 is moved. The extension operation is stopped, the energization of the electromagnet 66 is stopped, and the electromagnet 66 loses its magnetic force. Alternatively, a timer may be provided instead of the pressure-sensitive sensor, and after pressing by a spring force, the pressing state may be continued for a certain period of time, and the energization of the electromagnet 66 may be stopped during the pressing.

Next, the fourth cylinder 78 starts the shortening operation, and the third beam 72 returns to the position before descending, whereby the electromagnet 66 also rises. Thereafter, the shortening operation of the third air cylinder 74 is performed, and the horizontal motion beam 60 and the electromagnet 66 return to the transfer position. Next, after the sixth detecting means detects that the horizontal motion beam 60 has returned to the home position, the stopper 38 in FIG. 6 rises and the conveyor roll 36 starts rotating. Thus, the female backing paste operation is completed. FIG. 11 shows a series of work paths described above. The bonding of the male backing 4 is completed simultaneously with the female backing 6 by the male backing bonding device by the operation of the left and right hand difference by the male backing bonding device.
The ceiling plate 2 which is carried out from the box 6 and has the male backing 4 and the female backing 6 attached thereto is sent out to a packing step ST7, and in a packing step ST7, is packed in a packing machine and then stored in a warehouse. According to the first embodiment, since the flat portion 8 of the back ridge arranged upward in the back ridge positioning step ST5 can be turned downward by inversion in the back ridge attaching step ST6, the ceiling plate is formed in the gluing step ST3. The glue can be simultaneously sprayed onto the flat portion 8 of each of the back linings 2, the male back lining 4, and the female back lining 6 by the common nozzle 10 of the gluing machine, thereby streamlining the entire bonding process. it can. Further, in the back lining attaching step ST6, the back lining where both sides to which the glue is not sprayed is gripped by the clamp means 40 is inverted, and the portion where the glue is not sprayed is attracted by the magnet holder 58, Since it is possible to prevent the flat portion 8 of each backing on which the adhesive has been sprayed from being brought into contact with a portion other than the portion where the ceiling plate 2 is attached, it is possible to completely automate the attaching operation until the paste is applied to the ceiling plate 2. it can. Further, in the back lining attaching step ST6, the grasped back lining is temporarily moved from the region above the ceiling plate 2 to thereby attach the back lining bonding device 3 to the region above the ceiling plate 2.
It is possible to facilitate the maintenance and inspection of the back lining device 34 without complicating the structure 4. Furthermore, according to the present embodiment, the next control is sequentially performed after the operation of the air cylinder of the stopper 38 is completed, so that, for example, the first air cylinder 48 may fail during the operation. In this case, the operation completion signal will not be output,
There is an advantage that the operation related to the subsequent process does not proceed at the time of failure.

, And the positions of the female guides 30 and 32 are fixed, so that the distance g between the female back support attachment portion of the ceiling plate 2 and the female back support 6 is not changed by the change of the width b of the ceiling plate. On the other hand, the distance g between the male backing affixed portion of the ceiling board 2 and the male backing 4 increases with an increase in the width b of the ceiling board.
Therefore, in the back lining attaching step ST6, each lining is moved by the magnet holder 58 fixed to the horizontal movement beam 60 in the first embodiment, and the second movement is performed by the pair of clamping means 40 fixed to the horizontal movement beam 60. In either case of the two embodiments, the female backline application devices 34 and 134 need not be changed. On the other hand, the male backing bonding device may simply employ a stroke-adjustable third air cylinder capable of increasing the stroke by an increase in g. In the gluing step ST3, with an increase in the interval g,
It is necessary to change the spraying position of the glue on the ceiling plate on the male backing side by the gluing machine 12 or to additionally install necessary nozzles.

Correspondingly, in the apparatus for spraying the paste on the ceiling plate together with the backing as in the first embodiment, a mechanism for adjusting the position of the nozzle for spraying the paste on the male backing is simply provided by a gluing machine. 12 or simply increase the number of nozzles. (2) In the above embodiment, for example, when the air cylinder of the stopper 38 fails, the subsequent control is not performed, but in addition, for example, the first air cylinder 4
If the operation completion signal is not output within a predetermined time after the operation start signal of Step 8, the operation of the entire system, that is, all the operations of ST1 to ST6 may be stopped assuming that some kind of accident has occurred. (3) A large number of crimping means for the back ridge, that is, the magnet holder 58 (first embodiment) or the clamping means 40 (second embodiment) are provided in the longitudinal direction of the back ridge, so that the back ridge can be attached to the ceiling plate. It can be made uniform and reliable in the longitudinal direction. (4) For example, in response to a clamping error caused by the clamping means 40, for example, an optical sensor corresponding to both ends of the backing is disposed at a passing point of the backing, and one of the signals from these optical sensors is provided. When no signal is output, the operation may be stopped or an alarm buzzer may be issued assuming that a clamping error has occurred with respect to the backing. (5) For example, a proximity switch or a limit switch is installed on the lower surface of the first beam 42, and the clamp device 40
Is lowered to clamp the backing, it is detected and confirmed that the backing is in a predetermined position.
The piston of No. 8 may be shortened. (6) For example, a proximity switch or a limit switch for confirming the shortening of the clamp width (B in FIG. 7) of the clamp device 40 is installed, and after the backing is securely clamped,
The next step may be started.
