Description

[Detailed Description of the Invention] The present invention relates to an apparatus for feeding and taking out a workpiece to be pressed by placing it on a caulk plate to a multi-stage press in which a plurality of presses are arranged close to each other in parallel.

Normally, in a multi-stage hot press, when a workpiece made of a soft material such as particle board or hardboard is subjected to heat-pressure treatment, the workpiece, which has been appropriately preformed, is placed on a thin metal caulk plate. The material was transferred onto the hot plate of a multi-stage press at the same time via a supply device, and then taken out from the press via a take-out device after hot pressing.

However, preformed objects such as particle boards and hardboards described above can be made into products by simply subjecting them to heat and pressure treatment.
Although it is possible to achieve the desired purpose with just one multi-stage hot press, for example, if a thermoplastic resin adhesive is used to process objects such as door frames or resin laminates that are currently being assembled temporarily, In order to improve workability, it is necessary to maintain the adhesive at a high temperature and turn the adhesive into a gelatinous state to ensure good adhesion of the workpiece, as well as to obtain the effect of temporary compression. The workpiece placed on the coal plate is once fed onto the hot plate of a multi-stage hot press, the adhesive is turned into a gel state, and at the same time temporary compaction is applied, and then it is cold-pressed on the cold-press plate of a multi-stage cold press. It is necessary to process it by tightening it and make it into a product.

Furthermore, in the current manufacturing process for plywood using thermosetting resin adhesives, multiple sheets of plywood coated with adhesive are temporarily pressed together using a cold press, and then hot pressed using a multi-stage hot press to produce the product. However, in order to improve the workability, contrary to the method of hot pressing followed by cold pressing described above, the assembly board was placed on a coal plate and temporarily pressed with the cold pressing plate of a multistage cold press. After that, it can be manufactured into a product by heat-pressure treatment between the hot plates of a multi-stage hot press.

In other words, the device of the present invention is a device for feeding and taking out a workpiece placed on a coal board to and from two multistage presses arranged in close proximity and having at least different thermal conditions, using a simple mechanism. An embodiment of the present invention will be described below with reference to the accompanying drawings, starting with its configuration.

For convenience, this example shows a case where a thermoplastic resin adhesive is used for the object to be treated.

A multi-stage structure in which a plurality of hot plates 3 are disposed between an upper frame 1 and a lower frame 2 via appropriate supports, and a movable platen 5 can be raised and lowered by a ram cylinder 4 disposed on the lower frame 2. Install the hot press 6.

A multistage cold press 8 having the same mechanism as the multistage hot press 6 and having a cold press plate 7 which is in the same phase as the hot plate 3 and has the same number of stages when the press is opened is installed adjacent to the multistage hot press 6.

In the supply direction of the multi-stage hot press 6 and the take-out direction of the multi-stage cold press 8, a supply shelf 11 and a take-out shelf 12, which are fixed to a supply shelf frame 9 and a take-out shelf frame 10 that can be raised and lowered, respectively, are attached to the hot plate 3. Install the corresponding number of stages.

At this time, the supply shelf 11 and the take-out shelf 12 are structured to be divided at the center so as not to interfere with the passage of the pushing body and the take-out body, which will be described later.

Furthermore, two rails 13 are made to protrude from the upper frame 1 of the multistage hot press 6 and the multistage cold press 8 in the supply and takeout directions, and the pushing body 14 and the takeout body 15 are movably suspended and supported by wheels 16, A rail 13 can be moved up and away from a multi-stage hot press 6 and a multi-stage cold press 8.

A pair of hook rods 21 that can be raised and lowered by a small amount are attached to the front surfaces of the pushing body 14 and the extracting body 15 on the press side through connecting bodies 20 connected to the piston rods 19 of the fluid cylinders 18 installed on the brackets 17, respectively. When the press is opened, the number of hot plates is arranged at three intervals to allow convection.

The coal plate 23 on which the workpiece 22 is placed is made of a thin plate with good thermal conductivity, and in order to push the coal plates 23 together, the front and rear parts in the supply and take-out direction are bent or fixed at the corresponding locations. It has a blocking member 24 made of an interference material, and a small hole 25 in which the hooking rod 21 engages is bored near the blocking member 24.

At this time, the caul plate 23 is made longer than the dimensions of the hot plate 3 and cold pressure plate 7.

Next, the operation of this embodiment will be explained.

At the lower limit position of the supply shelf frame 9, the coal board 23 on which the workpieces 22 in a temporarily assembled state are placed is transferred from the uppermost supply shelf 11 through the coal board circulation device, and is sequentially raised intermittently. Place it on the supply shelves 11 of all stages.

Next, by the forward movement of the pushing body 14, the coal plate 23 on which the workpiece 22 is placed is transferred onto the hot plate 3 of the multi-stage hot press 6 at the same time, and then the pushing body 1
4 to return to its original position.

At the same time, the multi-stage hot press 6 is closed, and each hot plate 3
In between, the object to be treated 22 is slightly heated and pressed, and the thermoplastic resin adhesive is turned into a gelatinous state.

When the press is closed, the supply shelf frame 9 is lowered and, as in the above description, the supply shelf 11 is fully loaded with the coal board 23 on which the workpieces 22 are placed and is on standby.

After hot pressing, the multi-stage hot press 6 is opened, and with the supply shelves 11 and hot plates 3 of each stage in the same phase state, the forward movement of the pushing body 14 causes an impact on the rear end of the front coal plate 23. Member 24 and rear call plate 2
The front end blocking members 24 of No. 3 are abutted against each other, and when the pushing body 14 is at the forward limit position, the front call plate 23
are transferred onto the cold pressing plate 7 of the multi-stage cold press 8 at the same time.

During the above-mentioned pushing operation, the piston rod 19 is extended by the operation of the fluid cylinder 18, and the hook rod 21 located on the front side of the pushing body 14 rises slightly, causing a small hole 25 drilled in the rear end of the rear caul plate 23 to open. engaged with;
When the pushing body 14 retreats from the forward limit position, the rear caul plate 23 is pulled back onto each hot plate 3 of the multi-stage hot press 6, and thereafter the engagement between the small hole 25 of the caul plate 23 and the hook rod 21 is released. Then, the pushing body 14 returns to its original position.

By closing the presses of the multi-stage cold press 8 and the multi-stage hot press 6, the workpiece 22 on the coal plate 23 before being cold-pressed between the cold-pressing plates 7 is made into a product, and after being hot-pressed between the hot plates 3. As described above, the object to be treated 22 on the caulk plate 23 is made of thermoplastic resin adhesive in a gel state.

At the same time, the supply shelf 11 is fully loaded with coal boards 23 on which the next processed objects 22 are placed as described above.

The multi-stage cold press 8 and the multi-stage hot press 6 after cold pressing and hot pressing are simultaneously opened, and first the take-out body 15 moves forward, and in the process, the piston rod 19 is extended by the operation of the fluid cylinder 18, and the front surface of the take-out body 15 is moved forward. The hook bar 21 located at
moves up slightly and engages with the small hole 25 in the front end of the forward call plate 23 at its forward movement limit position.

After the above-mentioned engagement, the take-out body 15 retreats and is placed on the take-out shelf 12, releasing the engagement between the hooking rod 21 and the small hole 25, and placing the processed material 22 on the front call plate. 23 is transferred in all stages and returned to its original position.

Thereafter, the take-out shelf frame 10 is intermittently lowered for each stage, and from the take-out shelf 12 at the lowest stage, the call board 23 on which the previous product to be processed 22 is placed is taken out, and the product to be processed is taken out. The processed material 22 and the coal plate 23 are sorted, and the coal plate 23 is transported to the coal plate circulation device.

In addition, as described in the beginning, this embodiment describes the workpiece 22 using a thermoplastic resin adhesive, but when replacing this with a thermosetting resin adhesive, a multistage hot press 6 and a multistage cold press 6 are used. The position of the press 8 may be changed.

As described above, according to the device of the present invention, a coal board, on which a workpiece is placed and transferred, is supplied and taken out to two multi-stage presses that are arranged in close proximity and have at least different thermal conditions. A blocking member is provided at the front and rear of the direction, and a small hole is bored in the vicinity of the blocking member, and as the pushing body and the extracting body move towards and away from the multi-stage press, the coal plates are pushed together, and the feeding shelf, hot plate or cold It is possible to transfer between the pressure plate (generally called the clamping plate) and the take-out shelf, and to position the call plate by engaging the hook rod and the small hole, making it easy to perform supply and take-out operations that match the press cycle. The mechanism allows for smooth operation and improves work efficiency.
