Description

[Detailed description of the invention] This invention is based on a pallet for concrete blocks, in which a vibrator device and a heating device necessary for peeling off the pallet used for concrete block molding are provided on separate supports. This invention relates to a peeling device.

Concrete block pallets are usually used to form the surface part after construction when forming blocks for seawalls.The shape varies depending on the shape of the block, but it is usually The object has a shape as shown in Figure 3.

This pallet is then molded into blocks and does not peel off until curing is completed, and then peels off at the final stage.

Furthermore, once curing is complete, the pallets are attached to the surface of the blocks in a very close state, but when it comes time to peel them off, conventionally, they have to be peeled off one by one by hand.

However, this is extremely inconvenient,
It is clear that this method is not suitable for mass production.

Therefore, in order to avoid manual peeling work, the inventor of the present invention carried out an experiment in which a molded block was mounted on a table vibrator, and the pallet was stripped from the block by vibration. I found that when vibration was applied for a certain period of time, approximately 1% remained unseparated, and even if further vibration was applied to this 10%, many remained without being separated satisfactorily. be.

This seems to be due to the special close relationship with the concrete pallet, and it was found that such a thing cannot be separated by vibration.

In addition, in order to achieve peeling by vibration, it is necessary to use a long time, or even if it is possible, it is not acceptable to take a long time for peeling in a production process aimed at mass production. The vibration method is not perfect in that sense.

Therefore, the inventor of the present invention first installed a desired number of heat generators with the desired heat source at the block mounting position on the table surface of the table vibrator, applied vibration, and solved the difference in thermal expansion coefficient between the pallet and concrete. Focusing on this, we developed and provided to the world a pallet peeling device for concrete blocks that can completely peel pallets from blocks in a short time by using both of these methods (see Utility Model Application Publication No. 53-99356). However, since the heat generator and the vibrator were located too close to each other, it was difficult to remove the heat generator from the vibrator. It has been found that heat does not have a positive effect on the vibrator, but rather causes the vibrator to malfunction.

It has also been found that if the vibrations of the vibrator are transmitted to the heat generator, this may cause trouble to the heat generator and its electrical system.

Therefore, this idea consists of a peeling table with a heating plate attached to a lifting platform whose one end is rotatably pivoted, and a peeling table with a vibrator attached, with the former peeling table moving forward along the transport path of the concrete block. In addition, the latter stripping tables are arranged in a row at the rear, and the stripping table equipped with a heating plate and the peeling table equipped with a vibrator are separated, thereby severing the influence between them, and using a heater to block the pallets. This was developed for the purpose of providing a peeling device for concrete block pallets, which can release concrete blocks from close contact with the concrete block pallets and completely separate those that cannot be completely peeled off using a subsequent vibrator.

Next, one embodiment of the concrete block pallet peeling device according to this invention will be described based on the drawings.
B is a peeling table to which a heating plate 1 is attached, and B is a peeling table to which a vibrator 2 is attached.

Of these, the stripping table A will be described based on FIG. 6 is attached, and the cylinder 6 moves up and down by the action of the cylinder 6.

Reference numeral 7 denotes a conveyance rail, and the block 3 is conveyed on this rail 7 by a chain 8.

Reference numeral 9 denotes a stopper whose one end is rotatably connected by a pin 10 and whose other end is connected to a cylinder 11.

The blocks 3 with pallets attached are then lined up on the rail 7 by the chain 8 from the left side in FIG.

In this case, the cylinder 11 is actuated to raise the piston and cause the stopper 9 to protrude above the upper surface of the rail 7.

The block 3 is then conveyed onto the rail 7 using the chain 8.

As a result, the blocks 3 are arranged on the rail 7 at regular intervals.

Thereafter, the cylinder 6 is operated, its piston is extended, the lifting platform 4 is lifted, and the heating plate 1 attached to the lifting platform 4 is brought into contact with the pallet attached to the block 3.

This heats the pallet, expands it, and loosens the close contact with the block 3.

In some cases, the pallet is separated from the block 3 at this stage, but in others, the pallet cannot be completely removed.

However, after heating for a certain period of time, the cylinder 6 is activated again to lower the lifting platform 4, thereby separating the heating plate 1 from the pallet, and the other cylinder 11 is activated to lower the stopper 9 below the top surface of the rail 7. A chain 8 transports the block 3 on the rail 7 to a stripping table B equipped with a vibrator 2, which will be described below.

゛The configuration of the peeling table B will be described based on FIG. 2. In the same figure, 12 is a vibrator
A rail 13 is arranged above this table 12.

The vibrator 2 is connected to this rail 13, and a chain 14 is disposed on the rail 13.

Note that 15 in FIG. 2 is a cylinder for adjusting the angle of the rail 13.

The blocks 3 are then lined up on the rail 13 by the chain 14, and the vibrator 2 is activated.

Then, the vibration generated by this vibrator 2 is
The heat is transmitted to the pallet attached to the block 3 via the rail 13, and the pallet, which has become loosely attached due to thermal expansion, is completely separated from the block 3.

After being peeled off, if the block 3 is lifted up, only the pallets 1 to 1 will remain on the spot, and the block 3 and the pallet can be collected separately.

As mentioned above, according to the concrete block pallet peeling device according to this invention, the device for peeling by heating and the device for peeling by vibration are each configured separately, so the peeling work is performed in two stages. Therefore, most of it is peeled off by the initial heating expansion, but the remaining part is peeled off by vibration, so the peeling effect is thorough, and each peeling device does not affect each other. Therefore, it has the effect of being convenient for machine maintenance.
