Abstract

THE METHOD OF LOADING THE TRANSPORT TROLLEYS IN THE DRYING CAMERA by filling the cart placed on the boot lift with dried items, pushing the loaded cart onto the transporting lift and pushing the cart with the plunger into the drying chamber. and due to the fact that, in order to increase productivity by eliminating idling of both lifts, a stack of not less than two trucks is accumulated on the loading and transporting lifts, and another cart is filled at the same time while pushing the loaded cart, the elevator to the drying chamber is produced by the entire stack.

Description

The invention relates to the technique of drying products in transport carts and can be used in the woodworking and other industries of the domestic industry.

The known method of alternately loading transport trucks in the drying chamber f 3

A disadvantage of the known method of loading transport trucks into the drying chamber is the presence of idling of the traction mechanism.

The closest to the present invention is the method of loading the transport carts into the drying chamber by filling the trolley placed on the loading hoist with the goods to be dried, pushing the loaded trolley onto the transporting hoist and moving the trolley with the pusher into the drying chamber 2

The disadvantage of this method is also the presence of idling of both lifts.

. The purpose of the invention is to increase productivity by eliminating idling of both lifts.

This goal is achieved by the fact that according to the method of loading transport carts into the drying chamber by filling the cart placed on the loading hoist with the items to be dried, pushing the loaded one. carts on the transporting lift and moving the carriage with the help of a pusher into the drying chamber; on the loading and transporting lifts they pile up a stack of at least two carts; moreover, while pushing the loaded carriage, the next empty cart is simultaneously filled, and the carriage from the transporting hoist to the drying chambers are manufactured in the entire stack.

The drawing shows a lot of Russian drying installation, which can be implemented as a way to load transport trucks.

The installation consists of a drying tunnel 1, transport carts 2, roller conveyors 3 and, loading 5 and unloading 6 lifts and transporting lifts 7 and B with the corresponding pushers 9 and 10, mechanism 11 pushing the stack of carts 2 into the drying tunnel 1 and return mechanism 12 empty carts.

The transport trolley 2 in plan forms a double-sided comb. An e-child is a set of load-bearing elements arranged with a certain pitch one relative to another and interconnected by vertical connections. Trolley 2 asbestos rollers located on both sides.

Roller conveyors 3 and 4 are two combs, installed oppositely, with the open side facing each other. The comb provides the possibility of raising and lowering the transport trolley 2 through it.

The loading and transporting lifts 5 and 7 are arranged in series one after the other and constitute a system of vertical conveyors with a flexible connecting element, for example a chain, having bearing areas for the rollers of the carriages 2.

The pusher 9 moves the loaded truck 2 from the lift 5 to the transporting lift 7.

Lifts 8 and 6 are a similar system. The pusher 10 provides movement of the loaded truck 2 from the transporting lift 8 to the unloading lift 6 ..

The transport mechanism 11 is designed for stepping in a drying tunnel 1 of a pile of loaded carts 2. It consists of upper and lower chain loops that are interconnected by vertical rods.

The mechanism for returning empty transport trucks 12 is a chain conveyor, moving cyclically in the basement floor of tunnel 1. There are stops on the chain links carrying the trolleys 2.

The installation works as follows.

The part of the roller conveyor 3 enters the upper ridge of the transport trolley 2. Thereafter, the loading hoist 5 lifts the trolley 2 up by a step equal to the distance between the dies and stops to enter the next part. After the loading trolley 2 is lifted several steps (the number of steps is determined by the height of the trolley), the return mechanism 12 during the loading of the next part to the loading lift S is another empty trolley 2. Thereby, on the lift S, there is a supply of empty trucks 2, which ensures a constant download incoming parts to the camera. The loaded trolley 2 behind the load shaft of the next part is pushed by the pusher 9 along the guides to the bearing platforms of the transport hoist 7. In the lift 7, the cart 2 rises by a step equal to the height of the cart, freeing up space for the next cart 2. stack of carts. After the stack has been set, the pushing mechanism 11 moves the stack of carriages, loading all the russes of the drying tunnel 1. At the same time, loading of parts into the trolley on the loading elevator 5 continues. 3 Constantly shifting one step at loading into the drying tunnel 1 of the next stack, carts 2 pass through the drying tunnel 1 and get onto the transporting lift 8. The pusher 1O pushes the bottom one and the cart onto the unloading lift 6, which makes a step-down lowering of the carts, unloading parts from the trolley to the roller conveyor k. The sequence of the discharge operations is the inverse of the loading sequence. The empty body 2 of the unloading lift 6 falls on the stops of the chains of the return mechanism 12, which supplies empty trucks to the loading lift 5. The use of this method of loading transport trucks eliminates the idling of the lifts and thereby increases the productivity of the drying units without increasing the production area.
