To each of the plurality of working units provided in the respective steps in order to carry out each work, and to return the cart after the work in each working unit to the inlet side of the processing furnace in order along the cart return path In particular, the present invention is characterized in that even when the number of carts in the cart return path is reduced, the cart is appropriately returned to the inlet side of the processing furnace and guided to the processing furnace. Is.

  Conventionally, in order to efficiently manufacture a display device such as a plasma display panel, as shown in Patent Documents 1 to 3, a cart loaded with an object to be processed such as a glass panel for display is placed from the entrance to the exit of the processing furnace. Proposals have been made to sequentially guide and process an object to be processed in a processing furnace.

  And after processing a to-be-processed object in a processing furnace in this way, the chip | tip in the several working part provided in the cart return path for the processed cart taken out from the exit, for example, the glass panel for processed displays The chip-off work section that cuts and removes the tube, the panel removal work section that removes the processed display glass panel from the cart, and the panel loading work section that loads a new display glass panel on the cart are sequentially led to each work. At the same time, the carts that have completed the work in the respective working units are sequentially returned to the inlet side of the processing furnace along the cart return path, and are again guided from the inlet of the processing furnace into the processing furnace.

  Here, the processed cart taken out from the exit as described above is sequentially guided to a plurality of work units provided in the cart return path to perform each work, and the cart after the work in each work unit is completed is processed. When returning to the furnace entrance one after another, if the number of carts in the cart return path is sufficient for the time required for conveyance and processing, the carts that have completed the work in each work section Without delay, it is always returned to the inlet side of the processing furnace, and the cart loaded with new objects to be processed is guided in order from the inlet of the processing furnace to the processing furnace so that continuous processing can be performed. Become.

  However, since the cost of the cart is generally very high, in recent years, it has been desired to reduce the number of carts in the cart return path.

  However, when the number of carts in the cart return path is reduced, the transport time for sequentially leading the cart to the plurality of work units provided in the cart return path as described above becomes longer, and the work in each work unit becomes longer. There has been a problem that it is difficult to return the completed cart appropriately to the inlet side of the processing furnace and sequentially guide the cart loaded with new objects to be processed from the inlet of the processing furnace into the processing furnace.

Further , in Patent Document 3 , a driving device capable of running and stopping for each cart is provided, and the stopped cart is fixed with respect to the circulation path so that the cart can be freely engaged and disengaged. Some have been provided with matching locking devices .

However, in what is shown in Patent Document 3, the driving bar is rotated, the protrusions provided on the driving bar are engaged with the engaging portions of the carts, and the driving bar is driven in the forward direction. Each cart of the cart is advanced at a constant stroke at the same time, and then the drive bar is rotated in the opposite direction to disengage the protrusions from the engaging portions of the carts, and the carts are stopped. By driving the drive bar in the reverse direction and repeating these operations, the carts can be moved at a constant stroke at a stroke while repeatedly running and stopping. It is only shown to maintain the above, and means for solving the above problem is not shown. In addition, the working time in each of the above working parts is not constant. In particular, when the working time in one working part is longer than the working time in the other working part, the cart in the working part with the long working time is used. In general, the cart is moved in accordance with the end of work in the work section having a long work time, and the cart that has been completed in each work section is still moved to the entrance side of the processing furnace. There has been a problem that it is difficult to return appropriately and continuous processing cannot be performed stably.

  The present invention sequentially guides a cart loaded with objects to be processed from an inlet to an outlet of a processing furnace, processes the objects to be processed in the processing furnace, and sends the processed cart taken out from the outlet to the cart return path. To each of the plurality of working units provided in the respective steps in order to carry out each work, and to return the cart after the work in each working unit to the inlet side of the processing furnace in order along the cart return path It is an object of the present invention to solve the above-described problems in cart-type processing equipment.

  That is, according to the present invention, in the cart-type processing equipment as described above, the work time in each work section provided in the cart return path is not constant, and the time for the cart processing work to be completed in each work section. Even in different cases, the cart is properly returned to the inlet side of the processing furnace and guided to the processing furnace so that continuous processing can be performed stably even when the number of carts in the cart return path is reduced. It is an object to do.

In the present invention, in order to solve the above-described problems, the cart loaded with the objects to be processed is sequentially guided from the inlet to the outlet of the processing furnace, and the objects to be processed are processed in the processing furnace. The processed carts taken out are sequentially guided to a plurality of work units provided in the cart return path to perform each work, and the carts that have been completed in each work part are processed along the cart return path. In a cart-type processing facility that is sequentially returned to the furnace entrance side, reciprocatingly moves along the cart return path, and the work is completed in each work section in the cart on the cart return path. A timing at which the first return device and the second return device are provided to selectively move the cart in a movable state to the inlet side of the processing furnace, and the first return device and the second return device reciprocate. Was made different.

  Here, in order to change the reciprocating timing of the first returning device and the second returning device as described above, the reciprocating timing of the first returning device and the second returning device is reversed. Is preferred.

  Here, in this cart type processing facility, a display glass panel used for a display device such as a plasma display panel is used as an object to be loaded and processed in the cart.

For example, immediately after starting the operation of moving the cart to the inlet side of the processing furnace by the first return device. In addition, the cart which has become movable after the work in the working unit is completed is different in the timing of reciprocating with the first return device without waiting for the first return device to reciprocate and return. The two-return device is moved to the inlet side of the processing furnace, and the cart is appropriately returned to the inlet side of the processing furnace.

  In particular, when the timing at which the first return device and the second return device reciprocate is reversed, the work is completed and moved as compared with the case where the cart is moved to the inlet side of the processing furnace by one return device. The travel time of the cart that has become possible is shortened to a maximum of half, and the completed cart is properly returned to the inlet side of the processing furnace.

  As a result, the cart-type processing facility according to the present invention can perform stable and continuous processing even when the number of carts in the cart return path is reduced.
