Description

Drying in; 1 e1s technological onepauvieii, widely used in the production of furniture (gluing, cutting, finishing).

With a long drying time and a small operational rhythm of the flow lines, the capacity of the drying chambers is quite significant. Therefore, from the point of view of economy of production play-offs, the most appropriate is the use of vertical drying chambers.

The proposed vertical

-ai-regatta consists of a metal frame 1, a set of cassettes 2, a mechanism and lowering of the cassettes 3, a pushing mechanism of the cassettes 4, a fan 5, boxes 6 and a jury box 7.

The metal frame of the drying chamber is sheathed with asbestos-cement slabs to provide the necessary thermal insulation.

The cassettes that serve to place the products in them and transport them inside the drying unit are a tubular box, the bottom base of which has a wide opening for passing a conveyor or other conveyor-ioio, its devices delivering the product to the unit.

On the left side of the cassette, the right guides are usable, and 8, on the left-flat side, and 9. Guides serve to move the cassettes from one bag to another inside the drying unit.

Below the guides on each side of the cassettes are the support plates 10, with which the cassettes are raised and lowered.

The product freely lies inside the cassette; while moving the cassette in the drying chamber, the bottom cantilever tubes do not move relative to the cassette. The cassettes in contact with the product are glued with a soft material. In the process of lifting and lowering, the lower cassettes rest on the four paws of the 2 lifting mechanisms, and all the upper cassettes lie on top of each other. To prevent longitudinal displacement of the cassette, there are protrusions that move along vertical guide rails 13 located along the entire height of the vertical cassette run. The cassettes are in the drying unit with two feet.

The 1st of the foot goes up, the right goes down. The lifting mechanism for lowering cassettes (see Figs. 1 and 2) consists of eight lifting rods 14 and eight drain 15, driven by a hydraulic cylinder 16 m by means of crank shafts 17.

The rods end with an extension with their paws 12, which pick up the cassettes into the rear of the cassette and hold the bags of the cassettes as they move from one position to another. The retractable paw engages with the cassette at the time of ascent or descent, and is taken up with horizontal shuffling, cassettes. The movement 1ptan comes from two crank shafts 17 and connecting rods 18. The shafts are interconnected by a drive chain 19, which is moved by the hydraulic cylinder 16.

Pushing the cassettes from one foot to another, both upward of the package and below, is carried out by a carriage with grippers 20, driven by .in from the pneumatic cylinders 21, which operate synchronously.

The operation of the hydraulic lift cylinder and pneumatic cylinders of the pushing mechanism is controlled by an automatic electrical relay contact system.

The air heated by the heater 7 is supplied to the dry chamber by means of an axial fan 5 and moves along the surface of the products to be dried. Fresh air intake and contaminated emissions are effected through the respective outlets with dampers located on the air ducts.

The operation of the drying unit is carried out as follows. The lithium cell is supplied to the drying unit either by means of a pulsating transport device (when the unit is installed in an automatic line) or laid down in any other way (when the unit is operating outside the automatic line).

From., The spruce is installed under the left foot of the cassettes (see Fig. 3).

Thereafter, the cassette, located below, from the right foot pushes to the left. The product is included in the cassette. At the same time, insert the cassette from the left foot to the right. This frees up space for lifting the left foot of the cassettes and lowering the right one. Each cassette pack is supported by four legs. The other eight legs are at the bottom. At the time of lifting the left and right descent package, the legs move. Moreover, pod pimples capture the cassette with the product and lift it and the entire package on one schag. The packs that supported the left packet, while freely going down. The paws supporting the right bag are lowered and the lower cassette is placed on the guides of the drying chamber. Paws, moving up, pick up and lift the entire right package, freeing the lower cassette.

After that, the pushing mechanism pushes the right-side cassette pushed down the cassette to the left, and the dried product remains on the transporting device and moves to the right from the material unit as the conveyor moves; The cassette is moved to the new product that came up to the loading point.

The cassettes in the bag lie on top of each other, resting on the outermost guides. When lifting, the paws raise the cassettes by the support plates, which ensures that the lower cassette is unloaded from the bending forces under the influence of the weight of the leaching cassettes.

Subject invention

I. A vertical cluster cartridge cluster, for example, for drying furniture panels, consisting of a drying chamber with windows for blowing coolant perpendicular to the direction of movement of the cassettes, a ventilation calorifier installation and a transGrushing device, characterized in that, in order to increase productivity and saving production space, the transport device is made in the form of a multi-element mechanism consisting of a set of cassette-elements, lying freely on each other in two vertical lines experiences and moving in a closed path inside the core of the camera using shtangovogo lift-lowering mechanism with

driven by hydrocylipram and two pneumatic pushers at the top and bottom. 2. Vertical drying unit according to claim 1, characterized in that, in order to enable installation of the unit in automatic lines and to prevent the products from scoring from the lacquer film, the transport device cassettes have the form of a staple.
