Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic feeding and receiving device for metal plates in a metal plate printing or coating machine.

The purpose of the present invention is to continuously and automatically feed metal plates that are to be printed or coated (feeder), and to continuously and automatically receive printed or coated metal plates (stacker), thereby increasing work efficiency. This is an attempt to improve sexual performance.

In general, metal plate printing machines or coating machines require extremely high level of technical skill in order to continuously supply metal plates, so each pile (a stack of approximately 1000 metal plates) must be manually processed. Replacement is in progress.

For this reason, the machine temporarily enters a dry running state for each pile, and in order to guarantee printing quality, especially on printing lines, after running a dry run, the printing quality must be checked through a test printing board before starting actual printing. is common.

Therefore, there is a lot of waste, such as lost time and work effort due to manual pile replacement setup time, lost time of trial printing, and loss of trial printing plates.

The present invention was proposed to solve the above-mentioned conventional problems, and its features are that it automates the replacement of piles, maintains the automatic supply and receipt of metal plates even during the replacement, and This eliminates the need to run the paint machine (or paint machine) dry.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

In FIG. 1, A indicates the floor surface and B indicates the pit.

The printing machine (or coating machine) is installed on the floor, but this is omitted in the drawing.

The automatic metal plate feeding and receiving device of the present invention is installed at the metal plate feeding position and the metal plate delivery position of a circuit printing machine.

Although FIG. 1 shows the feeding device installed at the feeding position, the receiving device has almost the same main structure as the feeding device.

Therefore, the main components will be explained using the supply device as a representative.

1 is an elevator whose lowest position is inside the pit B.

This elevator 1 can be vertically raised and lowered by a guide bar 27 and a guide member 28 provided on a main frame 2 installed on a floor surface A, and includes a motor 9, a reducer 10, a rotating shaft 11, and a chain 12. Lifting and lowering operations such as rapid ascent, inching, and sudden descent are performed by the elevating drive device 3 consisting of the following.

A pallet platform 6 having a large number of rollers 7 is provided within the elevator 1.

The pallet platform 6 is a roller 5 installed on the floor of the elevator 1.
If the direction of a pallet carried onto a pallet mounting table 6 which is installed on a table 4 which rotates and moves slightly at the top thereof is misaligned, the pallet is rotated slightly to correct it.

The pallet mounting platform of the elevator on the receiving side is a slight rotation table 4.
is not necessary.

The pallet 25 placed on the pallet platform 6 of the elevator 1 has a recess 26 formed in its upper surface 25a into which a fork 17 (described later) is inserted, and the metal plate W is placed on the upper surface 25a.
5a, the recess 26 provides a space for inserting the fork 17.

Then, on the feeding position side, there are approximately 1000 unprinted metal plates W.
Pallets 25 stacked one pile at a time are carried in, and printed metal plates are stacked on the empty pallets at the delivery position.

A roller conveyor 24 was installed on the floor A toward the elevator 1 for carrying in the pallet 25, and a roller conveyor 24 was installed on the floor A on the side of the elevator 1 for carrying out the pallet 25, as shown in FIGS. 3 and 4. A pallet pull-out device 30 and a roller chute 43 are installed.

The pallet drawer device 30 has a plurality of drawer blocks 31 arranged in parallel that are moved forward and backward by a cylinder device 33, and a latch protrusion 32 that can be raised and lowered at the tip thereof is provided.

Reference numeral 29 in FIGS. 2 and 3 is a passing member protruding from the side of the pallet platform 6 for passing it to the pallet pull-out device 30. be.

Reference numeral 13 in FIG. 1 is a ruler that regulates the rear end of the metal plate W, and according to the size of the metal plate W, the drive device 15 and the operating shaft 1 are
4 enables automatic forward and backward positioning.

Furthermore, 34 in FIG. 5 is a ruler that regulates both sides of the metal plate W, and this also corresponds to the size of the metal plate W.
It is moved left and right by an operating shaft 36 to enable automatic positioning.

Further, FIGS. 6 and 7 show a forward sucker in which the stacked metal plates W are separated by suction one by one and fed to the feed roller 8.

That is, a swing arm 41 is fixed to both ends of a rotatable shaft 39, and swings back and forth by a guide shaft 42. A pair of left and right support arms 40 are fixed integrally to the shaft 39, and this support arm 40 is provided with an adsorption member 38 that is extendably held by a cylinder 37.

This forward soccer as well as the rulers 13 and 34 are arranged on the upper surface of the main frame 2.

Next, a fork device having an essential structure for the present invention will be explained.

This fork device is provided at both the feeding position and the feeding position.

To explain this using FIG. 1 as a representative example, a frame 16 installed on the floor A in line with the elevator 1 is provided with a horizontally angled frame 17.

A movable body 18 that can travel is guided by the guide frame 17 via rollers, and a fork 19 is fixed to the movable body 18.

Therefore, this fork 19 moves forward and backward in the horizontal direction perpendicular to the up-and-down direction of the elevator 1, and its forward and backward movement positions are slightly lower than the sending-out roller 8 on the feeding position side, and are slightly lower than the sending-out conveyor of the circuit on the sending-out position side. It is located at the bottom.

The mechanism for driving the fork 19 forward and backward is such that a chain 20 is suspended above the guide frame 17 by a sprocket, both ends of the chain 20 are connected to stops 21 on the moving body 18, and the sprocket is driven by a motor 23 with a speed reducer. It is configured to rotate forward and backward.

Reference numeral 22 indicates a stopper that restricts the forward end of the fork 19.

Next, the operation of the above configuration will be explained.

On the supply side, a pallet 2 on which metal plates W are stacked
5 is carried onto the pallet platform 6, and the metal plates W on the pallet 25 are fed one by one by the inching of the elevator 1 and the suction supply by the forward sucker. moves forward and pallet 2
5 and holds the metal plate W remaining on the pallet 25.

Therefore, the metal plate W held on the fork 19 continues to be supplied to the printing machine.

゛Meanwhile, the empty pallet 25 is suddenly lowered by the elevator 1 to replace the pile, and the pallet pull-out device 3
0 to the side and carried out by the roller chute 43.

After the empty pallet 25 is pulled out, the pallet 25 stacked with metal plates W on the roller conveyor 24 is moved to the elevator 1.
Then, the metal plate W is carried onto a pallet platform 6 inside the metal plate W, and is then rapidly raised by the elevator 1 until the top surface of the metal plate W reaches the lower surface of the fork 19, and thereafter the process is switched to upward inching.

When it is confirmed that the uppermost surface of the metal plate W has reached the lower surface of the fork 19, the fork 19 moves backward and returns to its original position, waiting until the next pallet exchange.When the fork 19 moves backward, it is held on the fork 19. The few remaining metal plates W that had been placed are automatically transferred to the metal plates W stacked on the pallet 25, and the metal plates W on the pallet 25 are automatically supplied again, even when replacing the pallet. The metal plates W are continuously supplied to a printing machine (or a coating machine).

On the other hand, the receiving side of the printed (painted) metal plate W is the elevator 1.
The metal plates W are sent out and stacked on the empty pallets carried onto the pallet mounting table 6 in the interior, and when a predetermined amount is reached, the fork 19 moves forward and receives the printed metal plate W on the fork 19.

During this time, the elevator 1 rapidly descends, the pallet is pulled out by the pallet pull-out device 30, and carried out of the machine, the empty pallet is carried into the elevator 1, and the pallet rises rapidly to the lower surface of the fork 19, after which it switches to downward inching.

And when the empty pallet reaches the bottom surface of the fork 19.

After confirming this, move the fork 19 backwards, and then
The printed metal plate W received on 9 is transferred onto an empty pallet.

Therefore, even on the receiving side, the receiving operation continues continuously when the pallet is replaced.

As described above, the apparatus of the present invention has the following effects.

■ A table is installed on the floor of the elevator on the metal plate feeding position side on multiple rollers that are rotated in forward and reverse directions by a drive device so that fine adjustments can be made, and a pallet platform with many rollers arranged side by side is installed on this table. This makes it easy to automatically correct the misalignment of the pallet stacked with metal plates carried into the elevator, and the metal plates can be fed correctly to the feed roller, ensuring correct printing. As a result, printing loss can be eliminated and quality can be improved.

■ Forks that move horizontally forward and backward are provided at the feeding and discharging positions of metal plates, and the upper surface of the pallet is provided with a recess into which the fork is inserted, so when replacing the pallet, the supply side The remaining metal plates are held by inserting them into the recesses with the advance of the fork, and the supply of metal plates continues. During this time, the empty pallet is lowered and taken out of the machine, and the pallet with stacked metal plates is carried into the machine. Therefore, the supply of metal plates can be carried out continuously without any interruption.

On the receiving side, when the pallet is full of printed metal plates, the fork moves forward and receives the metal plate sent out on the fork, and in the meantime, the empty pallet is exchanged with an empty pallet and the empty pallet is lifted up. By inserting the fork into the recess and retracting it, the metal plate on the fork is transferred onto the empty pallet, making it possible to receive continuously in response to the continuous supply from the supply side, thereby significantly improving productivity. .

■ As mentioned above, the ability to continuously receive and receive metal plates from both the supply and receiving sides eliminates the need for test printing after dry running due to interruptions in feeding and receiving, and the metal plates for test printing are eliminated. This has the practical benefit of eliminating board losses.
