MULTI-LAYER PLATE FEEDER - MATARANORDNING FÖR ETAGESKIVPRESS

The present invention relates to a multi-layer plate press feeder comprising a feed shelf with tablets for feeding tablets placed on top of tablets to a plate press.

In the production of plywood in the wood processing industry, plywood veneers are stacked on top of each other with their adhesive layers. The veneers are pushed towards the two fixed corner stops so that a flat, "hard" edge is formed between them. The opposite edge is variable, "soft", because the veneers are somewhat different in length, with length differences of up to 5 cm. Such a deposit or material may be pre-compressed, after which it is transferred to a plate press.

In the plate press, the first step is to transfer the substances from the ladel mapink to the different levels of the filling shelf, i.e. the tablets. This is usually done with a separate feeder. Several such feeders are known in the art. One method is to use a throwing roller that accelerates the ladel so that it slides along the surface of the tablet towards the stop. The next tablet then settles into the feed slot and the operation is repeated. Because the ladle is always centered from the "hard" edge, the ladle is fed into the filling shelf with the "soft" edge above. In this case, this method has the disadvantage that when the "soft" edge hits the tablet's response at a rapid rate, the veneer layers are easily broken and cracked. If the crack is long enough, it will cause the entire plate to be rejected. Pieces of veneer also come off the broken edge, some of which fly over the material, increasing the number of sweat plates.

Another solution is to use drive tablets which are themselves conveyors, "tape tablets". Generally, the conveyor belt type plane rotates when it enters the feeder and stops when the fed pad is in place. When all the tablets are full, they are driven into the press, which pushes the finished plates from the press into the emptying shelf. As the tablets begin to retract, the rotating belts pull out at a pull-out speed, leaving the deposits in the press. In this case, you need n pieces of tablet shelf n pieces of conveyor belts and tracks. This thus becomes a cumbersome and expensive solution. Also, maintenance is expensive and inconvenient when keeping a n "tape tablet" in good condition.

The object of the present invention is to eliminate the above-mentioned disadvantages. The device according to the invention, in which the feed shelf is periodically raised when it is filled so that the upper surface of each tablet is in turn substantially flush with the upper surface of the roller and / or belt conveyors for receiving the paste, is characterized in that some of the conveyors are mounted on tablets at the receiving station in the feed shelf, the conveyor being surrounded on all sides by the tablet.

The invention will now be described by way of example with reference to the accompanying drawing, in which

Figure 1 shows the plate press as a whole.

Figure 2 shows a side view of a feeding device according to the invention.

Figure 3 shows a top view of a feeding device according to the invention.

The plate press consists of a feed tray 1, a feed device 2, a filling shelf 3, a hot press 4, a discharge shelf 5, a discharge device 6, and a stacking platform 7 (Fig. 1). In addition, it has a protective curtain 8 which protects the rising rises in the filling shelf 3 from premature hardening due to the radiant heat from the press 4, the necessary machinery and working cylinders to perform various sub-functions, a heating system in the press and a shelf 9 for shelves. The press operates as follows: the ladelminkka 10 is pushed onto the feed tray 1 towards the stop. At the foot switch position, the top surface of the stack is adjusted to a suitable height for feeding the deposits 10 to the filling shelf 3 by the feeder 2. In the feeder 2, the roller 11 conveys the feeder 1 onto the multi-belt conveyor 12 protruding . The filling shelf is formed by a shelf with tablets, which moves in the height direction with hydraulic cylinders. When the device is filled, each tablet 13 alternately rises to the filling height, where the feed to the tablets is transferred from the feeder 2. When all the tablets are full, the tablets are driven into the press 4. These further push the finished plates into the emptying section 1. As the tablets 13 begin to retract, the retainer of the ovens lowers and concentrates the ovens in the desired position.

It will be clear to a person skilled in the art that the invention is not limited only to the above example, but its various embodiments may vary within the scope of the following claim. Thus, the traction drive of belt conveyors, the number and length of belts, and the dimensions of the belts in tablets and shelves may vary. The feeder is also not tied to any particular product, but the present invention can be applied to any transfer of flat-bottomed bodies.
