SU4130A1 - Transporter for flasks - Google Patents

Description

The present invention is intended to more fully and with a greater degree of mechanization in the use of a conventional lamellar (caterpillar) conveyor for moving the casting flasks. Flasks move in the proposed device not only along the upper branch of the conveyor (where, as usual, molded flasks placed on the metal pouring site are placed on it), but also along the lower branch, where the cooling flasks move in the opposite direction. In addition, the device automatically overloads the flasks onto another auxiliary conveyor, which can be used either for knocking out flasks directly on it or for transporting the flasks to the place of embossing.

In FIG. 1 is a side view of the proposed conveyor associated with auxiliary conveyors; FIG. 2 is a front view of the conveyor; FIG. 3 is a side view of the lower part of the conveyor with two pairs of hooks at the link.

A conventional conveyor with end drums 7 and 2 and with flat links (trolleys) 5 is adapted to reverse the bottom movement of the flasks by attaching hooks 4 to all links m 3, two hooks each.

The molded and fastened oYioKa 5 is placed on any link of the upper branch of the transporter (for example, at points O), with the hooks 4 must be between the handles of 6 flasks. The flask moves with the conveyor in the direction of the arrows, is poured with metal along the way and approaches the end drum 2. By this time the gate should already have solidified. At point 7, the link of the conveyor and the flask take an inclined position, which is why the flask begins to slide down until its hooks 4 hooks 4 by the handles 6; in position 8, the flask hangs on the hooks. Hanging on two of its handles, the flask drops down until

will not start moving horizontally along with the lower branch of the conveyor. During the horizontal movement of the hanging flask from position 9 to position 10, the casting cools down and becomes ready for packing.

The removal of the flask from the conveyor is located near the end drum 1. Below, under the main foundry conveyor, there is a small lifting track conveyor with end drums // and 12. One of these drums is kinematically connected to the drum /, which ensures the coordination of the movement of both conveyors.

Flask crawls over two track chains 13 of the lifting conveyor. The chains lift it and remove it from the hooks 4. In this case, the link of the main conveyor no longer has a translational movement, but a circular movement, since it rotates on the end drum /. Hooks 4, turning with a larger radius than the axes of 14 links, have a greater linear speed than the chains of the main and lifting conveyors, thanks to which they move forward from the handles of the flask 6, releasing them (position 15).

The flask, moving on the chains of the removal conveyor 13, reaches the position 16, where, tilting together with the links of the chains 13, it slides down onto the links of the chains 17 of the auxiliary conveyor. The end drum 19 of this conveyor is kinematically associated with the drums of the main and lifting conveyors, which ensures the necessary coordination of movements. The auxiliary trans: porter serves either to knock out the flasks directly on it, or to send the flasks to the place of the knockout. The tooth 18 of the links of the chains 17 of the auxiliary conveyor is supported by the flask, preventing it from sliding downwards.

The auxiliary conveyor chains 17 - pass between the chains 13 of the lifting conveyor, for which

the drum 19 enters slightly between the leading washers of the drum 12. Such an arrangement makes it possible to get any necessary for smooth transfer of the flasks, the angle of intersection of the paths along which the chains 13 and the chains 17 are moving. In position 20, the flask moves on the auxiliary conveyor.

Each link of the transporter can be supplied not with one but with two pairs of hooks and then the flask, during the return stroke along the lower branch of the conveyor, will hang on all four handles of its half (Fig. 3). The flask 21 stably, without being able to swing, hangs on the hooks 22 of the trolley 23.

Auto relaying

Flasks on the auxiliary conveyor is as follows: Flashes run over the auxiliary conveyor 24, which raises it, unloading hooks. When all the handles 25 of this flask are raised above the hooks 22, i.e. when the flask is completely on the transporter 24, then it will be affected by a mechanism (of any design) that stops it for a while, or even slides back so that the hook hooks will come out from under the handles. During this time, the auxiliary transporter 24 slides under the flask; then the mechanism ceases to hold the flask and it moves further by the conveyor 24. From this point on, the conveyors may diverge: the empty carts of the main conveyor will go to their end drum, and the auxiliary conveyor will carry the flasks to the place of knocking out.

If the conveyor 24 is placed somewhat lower, just so that the hanging flasks could not reach it a little, then, when the flask stops using the above mechanism, the barb of hooks will slide under the handles until the latter are released and all of the flask falls on the conveyor 24 .

The subject of the patent.

Conveyor for flasks consisting of individual flat links hinged to endless chains fitted with rollers rolling along supporting legs.

guides, characterized in that each flat link is provided with one or two pairs of hooks 4 in order to hold the flasks by the handles on the lower branch of the conveyor and transfer them to the second conveyor of the conventional device.
