Description

The invention relates to a slicer for food ge according to the preamble of claim 1.

Such a disc cutting machine is from DE-AS 23 43 287 be knows, between the rotatably arranged circular knife and this facing the table edge there is a slot, and on the take-off side of the housing a bar running approximately at the level of the working surface is classified as a stripper for cut goods and their remnants serves. The disadvantage here is that in this slot over time Cutting material residues or crumbs can accumulate, which affects the cleanability of the Disc cutting machine in this area difficult.  

Another disc cutting machine is known from the German Pa tent specification 33 04 274. This is an electric motor driven household cutting machine with a circular knife, in which the Guide surface for the material to be cut horizontally on a parallel to the measurement water plane or sectional plane sliding carriage is formed. On due to the tolerances of the housing, the circular knife, its attachment The guide for the slide and the slide must have a certain There is a safety distance between the slide and the circular knife to prevent the circular knife from cutting into the carriage. In In unfavorable cases, there is a relatively large distance between the sled and the circular knife, which means that the material to be cut is in the cutting area is not supported and can be distorted by the rotating knife, or tears at the edges or crumbles. On the waste side of the knife, d. H. on the side on which the cut material is released no support for the material to be cut, so that this z. B. can fall off the device into a bowl underneath. Torn off parts of the material to be cut z. T. in the lower part of the housing, where they not particularly easy to remove due to its constructive design are cash.  

From the German utility model 18 23 793 is a hand-operated Slice cutting machine with a round knife is known, in which the guide surface che for the material to be cut on both sides of the cutting plane or the Level of the knife edge extends. In which have the guide surface the table of the device is a narrow one, the lowest part of the round knife sers receiving groove formed, which has the disadvantage of poor foundation to be cleanable. The arrangement of the guide table for both sides ten of the cutting plane has the disadvantage that the cut material to be cut remains on the device and not immediately in a bowl below can fall, causing the operator to implement it.

The invention has for its object a disc cutting machine to create according to the preamble of claim 1, which at simp chem construction and easy cleanability provides good cutting results and in particular avoids tearing or distorting the material to be cut.

This object is achieved by the features of the characteristic Drawing part of claim 1. It remains between the Knife or the support rib and the guide surface for the material to be cut relatively wide gap, which is easy to remove fallen crumbs or other cut parts allows without the cutting result suffers. In particular, the guide surface on one arranged relative to the cutting area fixed table of the device his. Preferably, the channel or depression is so deep that it is up to lower end of the knife, preferably one approximately vertically first kenden circular knife reached. This means that after removing the knife from the Housing also the entire tub adjacent to the waste side of the circular knife the motor housing including its lower areas Cleaning accessible.

The development according to claim 4 enables one to below the height of the guide surface reaching despite the presence of a fixed support rib in the zero position and preferably a bit above can be brought into a position covering the knife edge. The Appropriate platen is sufficient  noticeably below the height of the crumb tray, so that it is under the crumb channel extending guides is easy to perform.

The further developments according to claims 5 and 6 serve for easy cleanability of the device and thus its user-friendliness, since after removal Knife no narrow gap between a support rib and the motor housing of the device This leaves something that would be more difficult to clean. The training according to claim 8 is easy to clean, since after removing or extending the An the crumb troughs in their front area on the surface of the guide surface che facing away side is also open, which further facilitates wiping. The side on which the operator is viewed is regarded as the front of the device stands and the material to be cut away from you is approximately parallel to the cutting plane on the measurement leads to.

The development according to claim 9 has the advantage that the support rib the Schlit lead and certainly a collision of the carriage and knife and an on cutting the knife in the carriage. Because the support rib is less Tolerances can have relative to the knife than the movably guided table, read smaller distances between the support surface and the cutting area of the knife are realizable act as this between the guide surface of the movably guided carriage and the cutting area of the knife is possible. Overall, larger tolerances approved and thus the manufacturing costs, for. B. ge by simpler guides be lowered. The further education according to claim 10 acts in the same direction, 11 further minimizing tolerance problems through the training according to claim can be changed. According to claim 12, the support rib can be used directly tion for the sled.

If the cutting machine has a fixed table with a guide surface and an optionally arranged, slidably guided slide with a Has guide surface, the support rib can be height-adjustable, so that it ever because it lies with its supporting edge at the level of one or the other guide surface and their various advantages described above. The next Education according to claim 14 shows how the support rib in a relatively simple way can be made movable. In particular, when using a  Round knife a guideway running along this between two parts the support rib be present, so that the support rib during its height adjustment The arrangement relative to the knife edge remains largely unchanged. The support rib can parallel to the cutting plane in two slidable shi ben-shaped parts can be divided, expediently the support surface on movable part is formed and overlaps the other.

The development according to claim 15 is a simple design by the lower support rib serves as a holder for the attachable raised support rib. The Further development according to claim 16 shows how a building always remains on the device can be used in two positions to form different support rib heights, which reduces the risk of losing an accessory and the tangible speed or availability of the part is increased.

The developments according to claims 17 and 18 cause the support rib a protective function, e.g. B. take over the leadership of a movable carriage can by keeping this sled away from the knife. The arrangement of the Support rib according to claim 19 has the advantage that a gebil through the support rib Avoided narrowing of the crumb channel and further facilitates cleanability becomes. The developments according to claim 20 name advantageous widths of the Support rib for good guidance and support of different cut materials.

The support rib can be in its front area over which the positioning plate extends stretches, tapered or have a recess into which the positioning plate engages in their maximum indented position. This is a compromise between good guidance of the material to be cut in the cutting area and on the other hand egg achieved a safe rest position of the positioning plate covering the knife edge, without the adapter plate being too thick or bent. This will create a good operational reliability of the device achieved with relatively little manufacturing effort. Furthermore, deviating from the development according to claim 8, the support rib can be up to to the front end of the device. On the one hand, this results in a good one Guide. It may also be advantageous to open the crumb channel through the support rib to keep their side facing the positioning plate closed or U-shaped where not significantly impeded by the removal of the crumbs, but on the other hand Contamination of the guides of the positioning plate can be reduced.

The invention is based on schematic drawings of execution examples explained in more detail. It shows:

The illustrated in FIGS. 1 to 4, electric motor driven household slicer has a front, that is, viewed from the operating side, in total amt L-shaped housing 2, which is divided housing in an upright motor 4 and on the feed side table 6 adjoining the material to be cut with a horizontal guide surface 8 for the material to be cut and guides 10 for a removable, displaceable carriage 12 . On the feed side of the Mo torgehäuses 4 a circular knife 14 is rotatably gela gerert in a known manner, the circumferential cutting edge lies in a vertical plane, which is hereinafter referred to as the cutting plane. On the delivery side, the circular knife 14 is covered with the exception of a front free area by a knife cover 16 attached to the motor housing 4 .

The lowest area of the circular knife 14 is also covered by the Messerabdek effect 16 , the lower area engages in a crumb groove 18 formed between the motor housing 4 and the table 6 . The crumb trough 18 has a bottom 20 , the surface 22 of which lies below the guide surface 8 of the table 6 and below the lowest point of the cutting edge of the circular knife 14 . The crumb tray 18 extends over the entire longitudinal extent of the device from front to back parallel to the cutting plane, so that the waste collecting therein can be easily wiped out or forward.

In front of the circular knife 14 extends parallel to the cutting plane, a setting plate 24 , which extends down to below the bottom 20 of the crumb trough 18 and engages in table 6 by means of guide elements (not shown) in guides (also not shown). An adjusting knob 26 arranged on the front of the table interacts with the guide means of the adjusting plate 24 in order to displace them transversely to the cutting plane in order to adjust the cutting width.

Under the front area of the circular knife 14 , ie below the cutting area in which the circular knife 14 interacts with the material to be cut, a support rib 30 projects vertically upward from the bottom 20 of the crumb trough 18 parallel to the cutting plane. The support rib 30 has a side surface facing the crumb trough 18 and parallel to the cutting plane, which is approximately 3 mm away from the cutting plane. The section of the support rib 30 lying closer to the knife has a waste-side, outer surface 34 parallel to the cutting plane, which lies at a distance of approximately 2 mm from the cutting plane ne, so that the supporting rib 30 is measured in this area transversely to the cutting plane, approximately 5 mm is thick. The support rib has a support surface 36 lying in the plane of the guide surface 8 of the table 6 at its highest point and has, moreover, seen normal to the cutting plane, the shape of a flat, elongated triangle with a flattening at the tip, which is formed by the support surface 36 is. To the rear, the support rib falls off with a surface 38 which drops at a constant distance from the cutting edge of the circular knife 14 to the bottom 20 of the crumb tray 18 . Towards the front, the top of the supporting rib 30 falls with a ramp surface 40 , which adjoins the supporting surface 36 and slopes downward to the bottom 20 of the crumb channel 18 , which forms an angle of approximately 33 ° with the guide surface 8 of the table 6 . In the area of the ramp surface 40 , the support rib 30 is formed narrower in that it has a lateral recess 42 extending over its entire height, the delimitation-side boundary surface and the subsequent waste-side edge of the bottom 20 of the crumb channel 18 lying approximately in the knife plane. The setting plate 24 has a recess 46 in its lower edge area for receiving the bottom 20 of the crumb tray 18 . The recess 46 is in its rear portion into an obliquely increasing recess 48, 40 may follow, pick up the contour of the ramp surface, the ramp surface 40th In this way, it is possible to bring the guide surface 50 of the positioning plate 24 lying above the recesses 46 and 48 beyond the section thickness zero into a position on the feed side of the cutting plane approximately flush with the side surface 32 of the support rib 30 , in which the setting plate 24 Front open loading area of the cutting edge of the circular knife 14 covered for security reasons. In Figs. 1 and 2, the positioning plate 24 is shown a security cover erge reproduced rest position in this, whereas it is shown in the illustration of FIG. 3 in egg ner position relative to the housing 2, which corresponds to a low cut thicknesses setting.

To operate the device according to FIGS. 1 to 3, the user has on hand 26 the desired cutting width by adjusting the setting plate 24 . Then he guides the material to be cut on the guide surface 8 of the table 6 and in contact with the surface 50 of the positioning plate 24 from front to back, ie in FIGS . 1 and 3 from left to right to the circular knife 14 and past it. The material to be cut is supported in the cutting area of the knife 14 on the support surface 36 of the support rib 30 , with any material to be cut hanging down the side of the guide surface 8 of the table 6 being lifted by the ramp surface 40 onto the support surface 36 . The circular knife 14 separates a disc that falls on the waste side of the motor housing 4 or the circular knife 14 from FIG .

In a modification of the illustrated embodiment, the support surface 36 can extend somewhat further forward from the cutting edge of the circular knife 14 to approximately below the most forwardly projecting part of the circular knife 14 , the ramp surface 40 being offset a corresponding distance forwards. According to a further modification, the ramp surface 40 can also be omitted and the support rib 30 extend at the height of the support surface 36 to the front end of the table 6 .

As a result, support for the material to be cut is also ensured at the moment in which the circular knife cuts into the material to be cut projecting up to the height or beyond the axis of rotation of the circular knife. Most important, however, is the support in the lower area, which is already achieved by the short, illustrated support surface 36 , since this in particular avoids tearing out the underside of the material to be cut if this is carried out directly above the level of the guide surface 8 of the table 6 lying area of the knife works together.

FIG. 4 shows the cutting machine according to FIGS. 1 to 3 with a carriage 12 placed over the table 6 . The carriage 12 has a table top 60 , which stood at a level from the cutting plane defined by the cutting edge 15 of the circular knife 14 and whose top side serves as a guide surface 62 for the material to be cut. The carriage has a downwardly directed side wall 64 on the feed side with a guide projection 66 directed towards the circular knife 14 , which engages in a guide groove 10 formed on the feed side on the table 6 . Furthermore, the carriage 12 has a support rib 68 which projects downward in the region of the edge of the Ti blade 6 adjacent to the circular knife 14 and has a guide recess 70 cooperating with this edge. An elevation support rib 72 is placed over the support rib 30 , which is supported on the support surface 36 , the side surface 32 and with a support foot 74 in the lower corner of the crumb tray 18 remote from the circular knife 14 . The elevation support rib 72 is measured normal to the cutting plane, narrower than the support rib 30 and extends at a small distance on the feed side from the cutting plane or the knife edge 15 . To the rear, the elevation support rib 72 extends approximately to the knife cover 16 and to the front somewhat further than the support rib 30 and has in its front area approximately to the front end of the ramp surface 40 and is secured against displacements parallel to the cutting plane by the triangular shape of the support rib 30 . The increase support rib 72 has a support surface 76 on its upper surface 76 , which lies in one plane with the guide surface 62 of the carriage 12 . The support surface 76 extends back to the Messerab cover 16 and forwards approximately to about the area of the lower end of the ram penfläche 40 of the support rib 30 and even has only a short gently sloping ramp surface or bevel at its front end to catch the cutting good thing to avoid. The increase support rib 72 does not require long ramps because its support surface 76 runs very close to the guide surface 62 of the table 12 and the material to be cut cannot therefore drop significantly.

In a modification of the embodiment of the carriage 12 and the increase support rib 72 shown in FIG. 4, an increase support rib can extend from the front end to the rear end of the device or over a substantial part of this length. In this case, a downwardly projecting rib is formed under the cover plate of the slide and engages in a guide groove of the increase support rib 72 lying under the cover plate. One of the support rib 68 corresponding, a support on the table 6 assuming support rib is omitted and the guide on the side of the table facing away from the Rundmes offers in this case no lateral guidance, but only a height support. The elevation support rib can also bear against the circular knife with a slight pretension, as a result of which an even better tolerance compensation is achieved, in particular if the slide on this elevation support rib is guided in the lateral direction. So that the crumb trough 18 can continue to perform its function, even when working with a slide and a riser support rib, the riser support rib can have openings that are designed so that the crumbs fall through.

The cutting apparatus according to Fig. 5 has a housing 502 having a vertically he stretching motor housing 504 and is viewed from the front L-shaped which extends away table 506 with a guide groove 510 remote from the circular knife 514 in its side. The table has a cover-side guide surface 508 , to which a crumb trough 518 with a lowered bottom connects the 520 to the circular knife 516 . From the bottom 520 , a guide part 531 of a support rib 530 extends upward, the slope-side surface of which extends in the sectional plane and serves as a guide for an increase support rib 572 mounted thereon. The elevation support rib 572 has a profile normal to the sectional plane, which corresponds approximately to that of the support rib 30 of the embodiment according to FIGS . 1 to 4 and below its cover-side surfaces on the feed side a flat Ausneh line 574 , which can accommodate the guide part 531 completely. The guide member 531 be sits essentially the same contour as the heightening support rib 572 , but is made somewhat lower and lies with its upper edge below the plane of the guide surface 508 of the table 506 . The top surface of the increase support rib 572 it extends, as well as in the support rib 32 according to FIGS. 1 to 4 through the sectional plane and has a front upwardly inclined ramp surface 540, which merges via a flat rounded supporting surface 536 in a falling along the diameter surface 538 .

The increase support rib 572 is shown in FIGS. 5 and 6 in its raised position, with a sliding carriage 512 placed on the table 506 and guided with a cover plate 560 , which has a cover-side guide surface 562 for the material to be cut is in the raised position the support surface 536 of the elevation support rib 572 is in one plane with the guide surface 562 of the table 512 , which for the rest largely covers the crumb tray 518 and reaches up to the elevation support rib 572 . In Fig. 5, the heights of the guide surface 508 of the table 506 and the guide surface 562 of the carriage 512 are indicated by broken lines accordingly designated. The increase support rib 572 be an arcuate slot 580 , which is guided in an arc around the center of the circular knife. A locking screw 582 is screwed through the elongated hole 580 into a threaded bore 584 of the guide rib 531 . After loosening this screw by means of its knurled grip part, the elevation support rib 572 can be shifted in height in an arc around the center point of the circular knife 514 , where the edge section 586 overlaps the recess 574 and points over the top surface section 538 and points on a corresponding underlying guide edge 588 the guide rib 531 takes over. Drag by screwing and fixed to the screw 582 to increase the supporting rib 572 determined in its upper position or in its upper position or its lower position, in which the support surface 536 to 508 of the table is at the height of the guide surface 506th

In the modified embodiment according to FIG. 7, a housing 702 has a motor housing 704 with a round knife 715 mounted thereon on the feed side and a table extending horizontally therefrom with a guide surface 708 . On the table is a slide 712 with a guide surface 762 leads ge. Between the table 706 and the circular knife 712 , a crumb groove 718 extends with a lowered, horizontal bottom 720 . Adjacent to the cutting plane, two guide pins 780 protrude from the floor 720 at a distance parallel to the cutting plane, onto which a support rib 730 can be attached. The circular knife 715 has no knife cover and the support rib extends with its entire width on the feed side of the cutting plane and in a small distance from this and engages from below in the position shown between the carriage 712 and the circular knife 715 and has a support surface 736 on the top side , which lies in the plane of the guide surface 762 of the carriage 712 . To use the device without the sled 712 with the guide of the cutting material on the guide surface 708 of the table 706 lifts to the support rib 730 of the guide pins 780 from, it pivots by 90 ° clockwise, with the with the carriage verwendba re raised portion 782 in the crumb trough 718 comes to rest and is inserted with uninterrupted lines 784 in this position guide openings in this position on the guide pins 780 , with a low support rib 730 extending at right angles to the increased support rib 782 protruding upwards and with its support surface 736 the height of the plane of the guide surface 708 of the table 706 . The lower support rib 730 extends at right angles to the raised support rib 782 and is formed in one piece with it and, when the raised support rib 782 is used, stands away from the housing on the drop side, as shown. The short support rib 730 is et wa corresponding to the support rib 30 of the embodiment according to FIGS. 1 to 4 in the direction of extension from front to back short, so that they fall from the material to be cut in this position hardly hindered. In order to further reduce such obstruction of the falling of the material to be cut, the openings 784 can be formed in the support rib 730 in such a way that when operating with the slide 712 and using the raised part 782, the short, low support rib moves away from the cutting area, preferably into the Area of the positioning plate, where it does not prevent, is offset. The carriage 712 can have a downwardly tapering guide rib on the underside of the edge region facing the circular knife 514 , as indicated by the broken lines 790 . This can engage in a guide groove on the support rib 782 indicated by the lines 792 . In this case, the support of the slide on the edge of the table 506 facing the knife 514 can be omitted.

A support rib extending along the feed side of the knife can be used for Feed side can be hinged to the housing to remove the measurement sers and to facilitate the cleaning of the area behind. Such Support rib can be locked in the operating position and folded into the crumb tray his.
