Conventional technology A processing device called a transfer machine is
It has multiple processing stations, each processing station is equipped with a dedicated processing machine, and the workpiece is sequentially transported to each processing station using a transfer bar, etc., and each processing station performs the prescribed processing to produce the product. It is something to be molded.

When transporting a workpiece from one processing station to the next processing station, such processing equipment can transport the workpiece directly using a transfer bar, or place and fix the workpiece on a pallet and transport it via the pallet. Large parts such as cylinder blocks are transported directly, but small parts such as connecting rods are transported using pallets.

Problems to be Solved by the Invention By the way, when a workpiece is transported using a pallet, the workpiece is fixed on the pallet by appropriate means and the workpiece is processed in this state at each processing station. When machining, it is extremely difficult to separate and remove chips during machining.
There have been problems in that chips remain on the workpiece, which may impede machining in subsequent processes or damage the workpiece or tool. In addition, tools are fed intermittently and large quantities of cutting oil are supplied to break the chips into smaller pieces for easier removal.
In either case, chips remain on the pallet, and the chips must be removed from the pallet after each process, resulting in very poor workability.

Furthermore, the pallet is provided with an appropriate clamping means for fixing the workpieces, but in order to automatically load and unload the workpieces, the clamping means must be automatically operated from the outside. In order to avoid interference with workpieces being carried in or carried out, the clamping means is operated from the bottom side of the pallet. Therefore, when it is necessary to once release the clamp of the workpiece in order to change the posture of the workpiece during processing, it is necessary to provide means for operating the clamping means below the pallet at that position. However, since transfer bars and the like for conveying the pallet are arranged below the pallet, it is difficult to arrange the transfer bar without interfering with these, and it is not possible to automatically change the clamping posture of the workpiece.

The reversing device included in the processing device with the above configuration is
The rotational lever is rotated by the extension and contraction operation of the gripping cylinder, and the pair of swinging levers are simultaneously swung by the rotational lever via the connecting rod and the driven lever to simultaneously move the gripping member in the axial direction. This grips or releases the pallet, rotates the rotary shaft by the expansion and contraction of the reversing cylinder, and causes a pair of sector gears to swing in the opposite direction via reversing driven arms provided at both ends of the rotary shaft. Each sector gear rotates a pinion gear, thereby simultaneously inverting the gripping members, inverting the pallet, and further raising and lowering the box frame by the expansion and contraction of the lifting cylinder.

Effects of the Invention According to this invention, since the reversing device is installed at the processing station at the start end and at the processing station at the end, when the workpieces placed on a pallet are fed to each processing station and processed, the workpieces are Since machining can be performed by supplying the pallet to each machining station while it is placed below the pallet, the chips generated during machining tend to fall under their own weight, so the chips can be easily separated, and the chips can be moved inside the workpiece. In addition, the separated chips will not remain on the pallet and will fall downwards, so these chips will not interfere with machining in the next process, and special This eliminates the need for extensive chip removal work, greatly improving work efficiency.

Further, the reversing device is configured such that the pair of gripping members are directly driven by each pinion gear and a sector gear, and each sector gear is driven by a single reversing cylinder via a rotation support shaft and a pair of reversing driven arms. Since the pair of gripping members are operated, the pair of gripping members reliably rotate angularly in synchronization, so that the pallet can be stably reversed and the drive unit can be made smaller. Furthermore, the pair of gripping members are mechanically interlocked via a rotating lever, a pair of connecting rods, and a pair of swinging levers, and the rotating lever is operated by a single gripping cylinder. Since the members reliably move in synchronization and the same distance, the pallet can be gripped without causing any displacement, and the drive section can be made smaller, making the entire reversing device more compact.
