Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel material reversing transfer apparatus used for stacking panel materials such as sizing panels for building and bundling them.

2. Description of the Related Art In general, panel materials such as sizing panels for construction are stacked in units of a certain number of units convenient for handling, for example, 8, 10, 12 or the like, united, packed and packed.

Such a panel material has a uniform cross-sectional shape in the long side direction, but often has an irregular cross section having a different thickness in the short side direction. When n pieces of such panel materials are stacked in the same direction,
The entire cross section is extremely irregular, which is not only inconvenient to handle but also may cause unexpected accidents due to collapse of the cargo.

Then, when (n / 2) sheets of n units are stacked,
A widely adopted method is to turn over the remaining (n / 2) panel materials and stack them upside down to obtain a stable rectangular cross section.

The applicant has previously proposed an apparatus for reversing and transferring the panel material (Japanese Patent Application Laid-Open No. 62-21652). This is configured by combining a first traversing conveyor for transporting the panel material in the horizontal direction, a reversing mechanism for reversing the panel material, and a second traversing conveyor for discharging the reversed panel material, On the downstream side of the second traversing conveyor, another discharge conveyor is disposed, and by the transfer mechanism, the inverted panel materials can be sequentially stacked on the discharge conveyor.

According to the conventional technique, the discharge conveyor is provided with the second
The transfer mechanism that transfers the panel material between the two is sucked and transported above the discharge conveyor to discharge the panel material on the second horizontal conveyor. Since it was a type of stacking on a conveyor, it was difficult to increase the operation speed more than a certain level,
There is a problem that even if the operation speed of the line is slow, it may be good, but if the speed is to be increased, it may be a constraint.

Therefore, an object of the present invention is to provide a guide member which can move back and forth in the downstream direction of the second traversing conveyor in order to increase the overall operation speed and increase the operation speed of the line. It is an object of the present invention to provide a reversing and transferring apparatus for a panel material which can sufficiently cope with a case.

Means for Solving the Problems The configuration of the present invention for achieving the above object comprises a first traversing conveyor arranged in multiple rows, a second traversing conveyor following each of the first traversing conveyors, A reversing mechanism disposed between the first traversing conveyor and the second traversing conveyor, and a guide member movable back and forth disposed along a downstream end of each of the second traversing conveyors. The gist of the invention is that each guide member made of a bar or a plate is advanced onto the discharge conveyor so as to extend the second traversing conveyor via a separate air cylinder.

In addition, each guide member can be formed from a vertical plate having an upper side that is obliquely downward in the distal direction.

Further, each guide member can include a roller along the upper side including the tip.

According to the configuration of the present invention, the panel material carried on the first traversing conveyor is reversed by the reversing mechanism, and is discharged via the second traversing conveyor via the guide member onto the discharge conveyor. Is done. This is because the panel material from the second traversing conveyor is conveyed to a position above the discharge conveyor by advancing the guide member, and subsequently can be dropped on the discharge conveyor by retreating the guide member.

If the guide member is formed by a vertical plate having an obliquely downward upper side, the guide member can smoothly transfer the panel material onto the discharge conveyor along the upper side, and minimize the left and right thickness, Downstream of the second traversing conveyor, it can be compactly arranged at the tip.

Also, if a roller is provided along the upper side of the guide member,
Separation of the guide member and the panel member is facilitated, and the panel member can be more smoothly transferred onto the discharge conveyor.
