DE556812C - Soap embossing press - Google Patents

Description

With the prior art it was not possible to cut whole and particularly long bars in pieces and subsequent embossing of the individual pieces in the press to get flawless, clean bars of soap in one operation.

The well-known machines for automatic cutting and pressing of soap worked only in an imperfect way, because the means employed were not suited to a greater one Number of bars of soap according to the distance between the individual embossing forms move apart and feed the embossing forms.

In these known machines, the moving apart is done by guide plates, which by appropriate inclination the bars of soap according to the individual embossing forms to lead. The further the outermost cut pieces have to be moved, especially with long bars, the more so the guide plates must be more inclined, as the feed distance when moving apart must be measured relatively short.

However, this strong inclination has the consequence that the edges when pushed forward of the bars of soap being squeezed and crumbs rubbed off into the embossing molds and have a disruptive effect when embossing. Furthermore, the cutting edges of the guide plates hit the row of soap bars when they penetrate not always exactly the kerf between the pieces, so that the soap bars experience further damage through the baffles due to the edges being sheared off. The sheared-off chunks get into the embossing molds and thus prevent the embossing from failing properly.

The present invention avoids all of these inconveniences. After this are entered in whole and cut into pieces in the press in a known manner Bolt perfectly in the required for the supply to the individual embossing forms Distances automatically moved apart in a manner known per se and fed to the individual embossing forms.

Fig. Ι shows a vertical longitudinal section of the press, Fig. 2 shows a table for moving apart of the cut soap bars in the closed state seen from above, Fig. 3 the same table in the open state, Fig. 4 a multiple feed chute.

The uncompressed long soap bars are placed in the hopper α and pushed by the pusher b through the cutting frame c and broken down into individual pieces, with the end waste falling down to the side and getting into collecting boxes.

On the grate d , the pieces are before being entered into the filling chutes e according to the distance between the ram and

Embossing forms moved apart, so that between two pieces a distance of about 20 mm is created.

Shortly before the pusher b moves forward, the grate d is pulled apart and the bars of soap resting on it move with it and, as the pusher moves forward, enter the individual feed chutes e. The latter are expanded like a funnel at the top, as can be seen in Fig. 4, and take the pieces properly even if they are not at the same distance on the grate or if they should have shifted a little on the grate. However, this is almost impossible, since the individual grate plates are grooved in the longitudinal direction, which means that the pieces are guided safely.

The individual pieces are removed from the filling chutes e by a pusher / and fed to the individual embossing dies g in a known manner.

Both pushers b and f are connected to one another and move forward or backward at the same time. Since the pusher / but the pieces must move a greater distance forward than the pusher b, the latter has a correspondingly dead gear. The plate h of the grate can be fixed while the plate is moved in the direction of the arrow to open or close the grate. The grate plates in between are automatically set at equal distances from one another as a result of the attached chain links k. The grate is opened during the retraction of the pusher on the second half of the path, while it closes on the first half of the route, also automatically from the mechanically moving parts of the press when the pusher retracts.

The mechanical parts for pulling apart and bringing together the plates i to h (Figs. 2 and 3) are not specifically indicated in the drawings, since they are irrelevant to the essence of the invention. The contraction can e.g. B. by a spring quickly, the moving apart by a thumb shaft and corresponding intermediate links take place more slowly.

Guide walls are attached to the outer sides of the plates i and h to take the bars of soap with them when they are moved together and not to let them fall off the table. Instead of the grate, another device for moving the bars of soap apart, such as a stretchable rubber sheet or the like, can also be used.

In themselves are devices for the automatic moving apart of bars of soap, which work in a similar or equivalent manner to the subject of the invention, known, but these are not used to press the bars of soap, but to hang up the the latter on drying racks after cutting soap bars into individual pieces. These known devices work partly in such a way that on a pull-apart Grate or bars of soap placed close together on an expandable plate by means of these flexible pads pulled apart or that from a row of closely spaced bars of soap the second bar is pushed out. On the other hand, there are also devices on automatic soap presses, by means of which several bars of soap are simultaneously fed to the embossing tools. These are but not about the processing of long bars that have been fed into the press without cutting, but from pieces that have already been cut and fed individually to the press.

The advantages of the invention 'are that a very large number of Individual molds arranged side by side and with the long soap bars can be loaded, and that the pieces through the spreading and feeding device will not be damaged in any way and no crumbs or chunks will be detached from them but the pieces get into the embossing molds completely undamaged and flawlessly.

Such a soap bar of about 800 mm length from the refrigerator is with a pressed with a single stroke and clean individual pieces obtained from it. Such a press too delivers cleanly embossed bars of soap up to 45 oookg in eight-hour operation.

The subject of the invention differs from the known soap presses not only in the pull-out device, which is new for soap presses, but also in the use of a second filling chute e, which has as many individual compartments as there are embossing molds, and which is in connection with the second pusher / a very safe insertion of the compacts into the embossing molds is guaranteed, since any small discrepancies that may still be present are compensated for by these intermediate links.

The latter device, like the pull-out device itself, can also do not damage the compacts in any way, but rather they are completely uninjured conveyed into the embossing forms.

Since a much larger number of bars of soap than known devices

moved towards each other and fed to the embossing forms in perfect condition can, a great technical advance is achieved as a result and the performance the press significantly increased.
