Abstract

PURPOSE:To reliably deliver plate-shaped objects one by one by pressing and hooking the lower plate-shaped object out of plate-shaped objects stacked staggeringly longitudinally in turn on a lifter end sucking the uppermost plate-shaped object to transfer it forward. CONSTITUTION:The rear end section of a veneer directly below at the rear side from the rear end of the uppermost veneer out of veneers stacked on a lifter 4 staggeringly longitudinally in turn is pressed and hooked. Then, the uppermost veneer is adsorbed by the suction port 10b of a rear nozzle 10 and transferred to the preset position, the vacuuming of the rear nozzle 10 is stopped, and the adsorbed veneer is released. Next, the front end section of the veneer directly below at the front side from the front end of the new uppermost veneer is pressed end hooked. The uppermost veneer is absorbed by the suction port 20b of a front nozzle 20 and transferred to the preset position, the vacuuming of the front nozzle 20 is stopped, and the absorbed veneer is released. Accordingly, stacked veneers can be reliably delivered one by one.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a mechanism for sending stacked plate-like objects such as plywood veneers one by one to the next process.

A structure in which the veneers are suctioned and transferred one by one (Utility Model No. 81-113745)
There is a number).

However, in the conventional mechanism described above, air is blown to the rear end side of the stacked veneers to prevent multiple veneers from being sucked in at the same time. Due to the action of the adhesive during the production of veneers and the spread of suction power through conduits existing in the wood grain, the veneers below are simultaneously sucked and multiple veneers are transported in a superposed state. There are problems with which the possibility cannot be completely excluded.

(Object of the Invention) In view of the above-mentioned circumstances, the present invention provides a feeding mechanism for plate-like objects that can completely eliminate the simultaneous suction of multiple veneers and reliably feed each veneer one by one. The purpose is to provide.

It is constructed by connecting pivotally supported air cylinders 62, 62 and levers 61, 61, and by driving the air cylinders 62, 62, the front locking par 60 swings forward, and the upper part of the lifter 4 is rotated. The intermittent overlapping portions on the front end side of the veneers stacked with forward and backward shifts, that is, the front end portions that do not overlap with the lower veneer, are pressed and locked from the L direction.

The rear locking mechanism 5 pivots the left and right ends of the rear locking bar 50, which is passed from side to side behind the upper part of the veneer, to the machine frame l so as to be able to swing. The rear locking bar 50 swings rearward by driving the air cylinders 52-52, and the lifter 4
It is configured to press and lock the intermittent overlapping portion of the rear end of the veneer, that is, the rear end portion that does not overlap with the lower veneer, which is stacked in a forward and backward manner.

The plywood veneer delivery mechanism constructed as described above operates as described below.

That is, if the uppermost veneer stacked on the lifter 4 while being alternately shifted back and forth is shifted forward and placed S,
The air cylinder 50 is driven to swing the rear locking par 51 to press and lock the rear end of the veneer on the lower side of the top veneer that is rearward of the rear end of the top veneer. , the vertical drive air cylinders 13 are driven to lower the nozzle 10 after the process.

At this time, the three-way valve 25 on the front nozzle 20 side is closed.
The three-way valve 15 on the rear nozzle 10 side is in the r-open state, and vacuum is being applied from the suction port tab of the rear nozzle IO.

Then, the suction port 10b of the rear nozzle 10 is attracted to the rear upper surface of the uppermost single plate, and the vertical drive air cylinder 13-13
is driven in reverse to raise the rear nozzle 10, lift the suction veneer to a predetermined position, and stop.

In response to a conveyance request signal from a post process (not shown), the horizontal drive cylinder 12 is driven to advance the rear nozzle 10 and convey the suction veneer to a predetermined forward position.

When the predetermined forward position is reached, the horizontal drive air cylinder 12
At the same time, the forward movement is stopped by the reed switch installed in the rear nozzle 10, and the three-way valve 15 on the rear nozzle 10 side is
Switching to open 1, stopping the vacuum of the rear nozzle 10 and opening the suction single plate, driving the horizontal drive air cylinder 12 in the opposite direction to start retracting the rear nozzle 10, and driving the Niji cylinder 52. The rear locking bar 50 is swung to release the lower veneer.

The released veneer is conveyed and moved forward by a drive roller 90 in a subsequent process, and is sent out of the apparatus.

At this point, the top veneer of the lifter 4 is placed with a shift toward the rear.

Then, in synchronization with the completion of the feeding of the veneer that was sent out first, the air cylinder 62 is driven to swing the front locking par 60 to move the lower veneer forward of the front end of the top veneer. The front end of the plate is pressed and locked, and the vertical drive air cylinder 23
- Drive 23 to lower the front nozzle 20. In addition, the three-way valves 25 on the front nozzle 20 side are switched to the r-open state, and the three-way valves 15 on the rear nozzle 10 side are switched to the r-closed state. It is in a state of being.

The suction port 20b of the front nozzle 20 attracts the front upper surface of the uppermost veneer, rises, lifts the suction veneer to a predetermined position, and stops.

In response to a transport request signal from a subsequent process, the horizontal drive air cylinder 22 is driven, the front nozzle 20 is advanced, and the suction veneer is transported to a predetermined position in front.

When the predetermined forward position is reached, the horizontal drive air cylinder 22
It is sensed by a reed switch installed in the vehicle and stops moving forward. At the same time, the three-way valve 25 on the front nozzle 20 side is switched to 1 open j, stopping the vacuum of the front nozzle 20 and opening the suction veneer, and driving the horizontal drive air cylinder 22 in the opposite direction. Then, the rear nozzle 20 starts retreating.

The released veneer is conveyed by the drive roller 90 in the post-process and sent out of the apparatus, and in synchronization with the completion of feeding of the veneer, the air cylinder 62 is driven to close the front locking bar 6.

Also, the three-way valves 15 on the rear nozzle lO side are switched to the r-open 1 state, the three-way valves 25 on the front nozzle 20 side are switched to the r-closed A state, and the air cylinder 50 and the vertical drive air cylinder 13 and 13 are driven, the rear locking bar 50 starts locking the rear of the veneer and the rear nozzle 10 starts lowering, and thereafter the above cycle is repeated.

Note that while the rear locking bar 50 swings when the veneer is completely advanced, the front locking bar 60 swings when the veneer is completely delivered. This is because if this is done when the veneer has finished moving forward, it will come into contact with the rear end of the delivered veneer.

In addition, in the above embodiment, the suction devices provided at the front and rear were configured to move forward to convey the suction veneer forward, but a conveyance roller is installed in the suction device to suction and convey the veneer. The veneer brought into contact with the roller may be transported forward by driving the transport roller.

(Effects of the Invention) According to the feeding mechanism for plate-like objects according to the present invention, the plate-like objects can be stacked on the lifter with a shift back and forth at an angle of 7r, and the lower plate-like objects can be secured by the locking means. At the same time, the uppermost plate-like object is sucked with a suction device and transported forward, thereby eliminating static electricity generated between the upper F plate-like objects and adhesive that oozed out from the surface during the production of the plate-like object. Due to the action of This allows for transmission.
