Description

GERMAN

The invention relates to a further embodiment of the one described in the main patent on casting molds attachable device with guide channels for charging the mold with core supports, in which the Conveying device for the core supports supplied as a string of box-shaped cross-section in an known way of two opposing, interlocked and at the same time as a separating device effective roles is formed.

The aim of the invention is to prevent the core support strand from slipping and sliding off when conveying and Avoid jamming when separating the individual pieces from the strand as well as the overall structure to simplify with reduced space requirements.

For this purpose, it is important in the invention that the teeth of the two rollers Form scissors-like saw teeth, which od in one role with pins. Like. Occupied and in the other Roll are provided with matching grooves on the pins, and that the continuous longitudinal gap opposite surface of the core support strand, some of which is provided with transverse incisions, openings carries, in which the pins of a role engage.

Another feature of the invention is that one roller carries an edge flange on one side, so that when several such roles are arranged side by side, the strand in a U-shaped guide runs and is thus secured against sliding sideways.

A substantial simplification is achieved according to the invention in that the possibly on End of slotted feed pipe for receiving the individual supports separated from the strand directly begins between the two supporting and at the same time separating roles.

Further details emerge from the following description of one shown in the drawing Embodiment.

Fig. 1 and 2 show the core support cord in two different positions;

Fig. 3 schematically illustrates a settling device with a strand conveying and separating device and with the sliding tubes leading to the casting mold for the separated individual supports;

Figures 4 and 5 illustrate, on a larger scale, side and end views of the details of the conveyor and severing rollers represent.

The strand 1 consisting of any number of core supports with the continuous gap 2, the separating joints 3 and the connected back 4 corresponds to the embodiment described in the main patent, with the difference that the individual supports on the back are also provided with openings 21 , as shown in Fig. 1 and 2 can be seen.

As shown in FIG. 3, the strand 1 is wound up in a hinged magazine 20 of the depositing device 19 to form a roll 5 , but can also be introduced in a straight line, as already indicated in the main patent.

The beginning of the strand is hung with a hole 21 in a rotating roller 22 , which is provided for this purpose with pins 23 which are located on the back of saw teeth 24 on the circumference of the roller. The roller 22 carries a flange or collar 25 on one side in addition to the saw teeth.

The oppositely rotating counter-roller 26 also has a saw toothing 27 on the circumference, which is directed in the opposite direction to the saw teeth 24 of the roller 22 and carries holes 28 into which the pins 23 of the roller 22 can engage.

If the strand 1 grasped by the pins 23 and secured against sliding off by the flanges 25 reaches the point at which the saw teeth 24, 27 of the rollers 22, 26 intermesh, one support is separated in each case. The cut piece falls into a feed pipe 30 which begins immediately below the cut point and is adapted to the cross-sectional shape of the supports, in the present case therefore rectangular, which runs obliquely downwards to the sharp kink point 31 and then merges into the pipe 14 leading into the casting mold 15 . At the inflection point, the sloping core support is rotated by 90 ° in its fall position. In the example chosen, the conveyor and separating device is driven by

t 064 205 a linkage 32 which is pivotably arranged on the shaft 33 and engages with a pawl 34 in a ratchet wheel 35 which is fastened on the shaft 33 and which is always advanced by one tooth. The pitch of the ratchet wheel 35 is adapted to the pitch of the roller teeth 24. The movement of the ratchet and ratchet wheel 35 is transmitted by a pinion 36 seated on the shaft 33 to a gear 37 which is arranged on the shaft of the roller 22. The number of roller sets 22, 26 and the pipe strings 30, 14 depends on the respective placement point for supports in the casting mold. The drive device 32, on the other hand, is only provided once. In the details, in particular the drive, modifications of the embodiment shown are of course possible without deviating from the essence and scope of the invention. Patent claims: 1. Device with guide channels that can be placed on casting molds for charging the mold with core supports according to patent 1 045 052, in which the conveying device for the core support string consists of two there is counter-rotating, interlocked and at the same time effective as a separating device rollers, characterized in that the toothing of the two rollers (22, 26) form saw teeth (24, 27) , which in one roller (22) with pins (23) or the like . occupied and in the other roll (26) are provided with recesses (28) that match the pins (23) , and that the surface of the core support strand (1) which is opposite the continuous longitudinal gap (2) and is partially provided with ίο Ou notches (3) carries openings (21) into which the pins (23) of one roller (22) engage. 2. Apparatus according to claim 1, characterized in that the one roller (22) on one side carries an edge flange (25) so that when several rollers are arranged side by side, the strand (1) runs in a U- shaped guide. 3. Device according to claims 1 and 2, characterized in that the feed pipe (30), optionally divided at the end, for the supports separated from the strand (1 ) begins directly between the two rollers (22, 26).
