Abstract

The invention relates to a slicer for food, comprising a motor-driven blade (1), a carriage (3) that can be moved back and forth essentially parallel to the cutting plane of the blade (1) and has a bearing surface (4) for the product to be sliced, positioning means for positioning the product to be sliced in the direction of movement of the carriage (3), and remainder holding means (11) comprising a plurality of interspaced holding elements (12) that can be arranged on the side of the product to be sliced, opposite the blade (1), during the slicing process. The holding elements (12) extend perpendicularly to the bearing surface (4) when the remainder holding means (11) is in the position of use.

Description

WO 2008/135235 PCT/EP2008/003546 "Slicer for food" The present invention relates to a slicer according to the precharacterizing clause of claim 1. 5 A slicer of this type is known from EP 1 529 609 Al. In the case of the slicer described therein, the contact means and the scraps retaining means are formed by interlaced, horizontally extending, comb-like 10 structures. This is disadvantageous insofar as the scraps retaining means cannot be removed from the supporting surface or can be removed only with a large effort such that an excessively large product to be sliced can be placed thereon. 15 The problem on which the present invention is based is to provide a slicer of the type mentioned at the beginning which permits simple removal of the scraps retaining means from the supporting surface. 20 This is achieved according to the invention by a slicer of the type mentioned at the beginning having the characterizing features of claim 1. The dependent claims relate to preferred refinements of the 25 invention. The retaining elements can form a downwardly open, comb-like structure which can engage around a contact bar surrounded by the contact means. As a result, the 30 scraps retaining means can be designed in a manner such that they can be pivoted away or pushed away upward. Further features and advantages of the present invention become clear using the description below of 35 preferred exemplary embodiments with reference to the attached drawings, in which WO 2008/135235 - 2 - PCT/EP2008/003546 fig. 1 shows a top view of an embodiment of a slicer according to the invention; fig. 2 shows a section according to the arrows II-II 5 in fig. 1; fig. 3 shows a side view of the slicer according to fig. 1; 10 fig. 4 shows a side view, corresponding to fig. 3, of the slicer with the pivoting arm pivoted upward, fig. 5 shows a side view of a further embodiment of a 15 slicer according to the invention; fig. 6 shows a partially sectioned detailed view of the scraps retaining means of the slicer according to fig. 5. 20 In the two embodiments (fig. 1 to fig. 4, and fig. 5 and fig. 6), identical or functionally identical parts are provided with the same reference numbers. The embodiments of a slicer according to the invention that 25 are depicted in the figures comprise a motor-driven blade 1 designed as a circular blade, a stop plate 2, which is oriented parallel to the slicing plane of the blade, to predetermine the slice thickness, and a carriage 3 which is displaceable to and fro parallel to 30 the slicing plane and has a supporting surface 4. The carriage 3 can be displaceable manually and/or semi automatically and/or automatically. The carriage 3 has a U-shaped cross section with a 35 boundary wall 5 which is at the front, or is on the left in fig. 2 and fig. 3, and serves as a fixed contact for the product to be sliced, and a boundary wall 6 which is at the rear, or is on the right in fig.

WO 2008/135235 - 3 - PCT/EP2008/003546 2 and fig. 3. The boundary walls 5, 6 extend upward from the supporting surface 4 and approximately in the direction of the axis of the blade 1 or perpendicularly to the slicing plane. 5 The slicer furthermore has a displaceable contact bar 7 which extends between the boundary walls 5, 6 and parallel thereto above the supporting surface 4. The contact bar 7 is displaceable in the direction of 10 movement (see double arrow 8 in fig. 3) of the carriage 3 owing to a holder 10 which is displaceable on a rod 9. A product to be sliced can be held between the boundary wall 5 and the contact bar 7. For example, fig. 5 shows the contact bar 7 in a position which is 15 displaced comparatively far to the left and in which it can secure a comparatively small product to be sliced 20. The slicer furthermore comprises scraps retaining means 20 11 which have a plurality of retaining elements 12. Said retaining elements 12 here are designed as thin, web-shaped parts which are connected to one another on their upper side by a transverse web 13 in such a manner that a downwardly open, comb-like structure is 25 produced. The transverse web 13 is coupled to a pivoting arm 14 which is pivotable about an axis 17 extending parallel to the movable contact bar 7. The pivoting arm 14 can be pivoted in the clockwise direction out of the position shown in fig. 1 to fig. 3 30 into the position depicted in fig. 4 in such a manner that the retaining elements 12 are no longer arranged above the supporting surface 4. In this state, a large product to be sliced, such as, for example, a Bologna sausage, can be placed onto the supporting surface 4 35 without the scraps retaining means 11 being able to obstruct said supporting operation.

WO 2008/135235 - 4 - PCT/EP2008/003546 A parallel arm 18 (see fig. 3) runs parallel to the pivoting arm 14 and can be pivoted together with the pivoting arm 14 and is connected to the latter in an articulated manner via a pivot point 19. The parallel 5 arm 18 ensures that the scraps retaining means 11 can execute an approximately linear movement at least just above the supporting surface 4. Instead of pivotable scraps retaining means 11, it is 10 also possible, for example, for scraps retaining means which are displaceable upward linearly to be provided. In the position depicted in fig. 1 to fig. 3 and fig. 5, the contact bar 7 extends between two retaining 15 elements 12. The upper side of the contact bar 7 is provided with a chamfer 16 (see fig. 3) making it easier for the retaining elements 12 to pivot or slide past from above. The approximately linear movement ensured by the parallel arm 18 makes it easier to place 20 the retaining elements 12 from above onto the contact bar 7. In the embodiment according to fig. 5 and fig. 6, the scraps retaining means 11 comprise a holder 21 which is 25 attached on one side to the pivoting arm 14 and is connected on the other side to the retaining elements 12 via two guide rods 22, 23. Two springs 24, 25, 26, 27 serving as spring means are arranged in each case on the guide rods 22, 23. In this case, the retaining 30 elements 12 are displaceable to and fro relative to the holder 21 in the direction of the arrow 28 counter to the force of the spring means surrounded by the scraps retaining means 11 or parallel to the supporting surface 4. As a result, when the retaining elements 12 35 are lowered from above onto the contact bar 7, the retaining elements 12 can be displaced laterally in such a manner that the contact bar 7 engages precisely in a gap between two retaining elements 12.

WO 2008/135235 - 5 - PCT/EP2008/003546 The scraps retaining means 11 can be slid from behind up to the product to be sliced. For this purpose, the scraps retaining means 11 are displaceable on a rod 15 5 in the direction of the blade 1. An automatic feed can furthermore be provided, said feed, after a slice has been sliced off, advancing the scraps retaining means 11 for a distance toward the blade 1 in order to press the product to be sliced onto the stop plate 2 again 10 each time a slice has been sliced off. Said feed can be coupled mechanically or electronically to the carriage movement. In this case, the retaining elements 12 can press the product to be sliced against the stop plate 2 until none of the product remains. This is possible 15 because the retaining elements 12 can be slid up to the stop plate 2. It is possible, instead of a vertically oriented blade 1 and a horizontally oriented supporting surface 4 of 20 the carriage 3, for a blade which is tilted in relation to the vertical and a supporting surface which is correspondingly tilted in relation to the horizontal to be provided. This results in a "gravitational slicing mechanism" because the product to be sliced is pressed 25 by its own weight on the tilted supporting surface against the stop plate.
