Definitions

  • the present invention relates to a food cutting machine according to the preamble of claim 1.
  • a cutting machine of the aforementioned type is from the WO 2008/135 235 A1 known.
  • the cutting machine described therein comprises a rotatable, motor-driven cutting knife and a carriage with a support surface for the material to be cut, which is moved back and forth relative to the cutting knife to feed the material to be cut.
  • the cutting machine further comprises a residue holder which has a plurality of holding elements which are arranged next to one another at a distance from one another in the direction of movement of the carriage, the holding elements resting against the material to be cut during the cutting process on the side of the material to be cut that is remote from the cutting knife.
  • the cutting machine further comprises a contact bar which is designed to rest on the material to be cut on the support surface of the carriage. The holding elements can be moved together in the direction of movement of the carriage so that when the holding elements are lowered, the contact bar is received between two adjacent holding elements.
  • the disadvantage here is that, particularly when the holding elements are made of a very hard material such as stainless steel, the contact strip is damaged by the holding elements sliding past it on the side. Therefore, with such a design of the holding elements, the contact strip must also be made of a very hard material such as stainless steel. Overall, this leads to a very cost-intensive design of the leftover holder and the contact bar.
  • the problem underlying the present invention is the creation of a cutting machine of the type mentioned at the outset, which can at least partially be manufactured more cost-effectively and in which, in particular, damage to the contact strip caused by the holding elements is reduced or avoided.
  • the at least one holding element is made of plastic or comprises plastic.
  • a corresponding holding element can be produced cost-effectively, in particular an injection molding process can be used.
  • damage to the contact strip caused by the at least one holding element can be reduced or avoided.
  • Another advantage is that a holding element that is at least partially made of plastic is lighter.
  • the cutting machine comprises a contact bar which is designed to rest on the material to be cut located on the support surface of the carriage.
  • the contact bar can consist of a material that is different from steel or can include a material that is different from steel, in particular where the contact bar is made of aluminum or includes aluminum. Due to the holding elements at least partially made of plastic, the contact strip can be made of a less hard material, in particular at least partially of a cost-effective material such as aluminum be manufactured. This further reduces the manufacturing costs of the cutting machine.
  • the contact bar is displaceable in the direction of movement of the carriage and/or that the contact bar extends perpendicular to the cutting plane of the cutting knife. Due to the displaceability, the position of the contact bar can be adjusted to the thickness of the material to be cut.
  • the leftover holder has a plurality of holding elements which are arranged next to one another at a distance from one another in the direction of movement of the carriage, in particular wherein the distance between the holding elements from one another can be changed in the direction of movement of the carriage.
  • the rest holder can be set up to be applied to the contact strip from above in such a way that the contact strip is arranged between two mutually spaced parts of the holding element or two adjacent holding elements, in particular whereby when the rest holder is applied to the contact strip, the distance between these two adjacent ones Holding elements are enlarged relative to each other in the direction of movement of the carriage.
  • the possibility of changing the distance between the holding elements in the direction of movement of the carriage makes it easier for the two adjacent holding elements to slide past the contact bar. This further reduces the risk of damaging the system bar.
  • the leftover holder prefferably has a rod on which the at least one holding element is attached so that it can be moved in the direction of movement of the carriage. It can be provided that the rest holder has at least one spring arranged on the rod and is set up so that the at least one holding element on the rod against the force of the at least one spring can be moved. This makes it possible to change the distance between the holding elements in the direction of movement of the carriage using simple means, with the spring returning the holding elements that have been pressed apart back into the original position after they have been removed from the contact bar.
  • the holding element has several tips at its lower end in the position of use or that the holding elements each have a tip at their lower end in the position of use. This design also makes it easier for the two mutually spaced parts of the holding element or the two adjacent holding elements to slide past the contact strip.
  • the at least one holding element extends perpendicular to the support surface in the use position of the leftover holder. Furthermore, the parts of the holding element that are spaced apart from one another or the holding elements can be arranged parallel to one another. Preferably, the mutually spaced parts of the holding element or the holding elements in the leftover holder can be arranged in a comb-like structure which is open towards the support surface in the use position of the leftover holder.
  • the leftover holder can be moved from a first position, which corresponds to the position of use, to a second position in which it is removed from the support surface in such a way that larger items to be cut can be placed on the support surface.
  • the leftover holder can be pivoted about an axis from the first to the second position, which extends in particular perpendicular to the cutting plane. Allows the leftover holder to be pivoted away from the support surface Not only does it make it easier to place larger pieces of food, but it also makes it easier to clean the support surface.
  • the cutting machine includes a stop plate for the material to be cut, whose distance from the cutting plane determines the thickness of cut slices of material to be cut.
  • a pure protective plate or protective strip can also be provided, which covers the cutting blade against access. This protective plate or protective strip could then be at an uncontrollable distance from the knife so that slices could be cut.
  • a material feed would then always feed or pre-clock the material to be cut to the cutting plane in the desired cutting thickness.
  • the embodiment of a cutting machine for food shown in the figures comprises a rotatable cutting knife 1, which is in one during operation of the cutting machine Rotates the cutting plane and cuts off slices of material not shown in a cutting area (see Fig. 1 to Fig. 3 ).
  • the cutting machine further comprises a housing 2, designed in particular as a motor housing, in which a motor (not shown) is arranged which drives the cutting knife 1 (see Fig. 2 ).
  • the housing 2 can alternatively also be designed as a machine housing.
  • the cutting machine further comprises a carriage 3 with a support surface 4 for the material to be cut, which can be moved back and forth relative to the cutting knife 1.
  • the carriage 3 can be moved manually and/or semi-automatically and/or automatically.
  • a residue holder 5 is arranged on the carriage 3, with which the material to be cut can be held during the cutting process (see Fig. 1 ).
  • the cutting machine further includes a stop plate 6 for the material to be cut, which can be moved parallel to the knife axis of the cutting knife 1. By changing the distance of the stop plate 6 from the cutting plane of the cutting knife 1, the thickness of the cut material can be specified.
  • a pure protective plate or protective strip can also be provided, which covers the cutting knife 1 against access. This protective plate or protective strip could then be at an uncontrollable distance from the knife so that slices could be cut. A material feed would then always feed or pre-clock the material to be cut to the cutting plane in the desired cutting thickness.
  • the cutting machine further comprises a knife protection ring 7, which partially surrounds the outer edge of the cutting knife 1 at least above the top of the cutting knife 1.
  • the cutting machine further comprises a chain frame 8 with at least one chain 9, in particular a plurality of mutually parallel chains 9, for transporting cut slices of material to be cut from the cutting plane, the chains 9 rotating over two axes of rotation 10, 11 (see Fig. 2 ).
  • a chain frame 8 with at least one chain 9, in particular a plurality of mutually parallel chains 9, for transporting cut slices of material to be cut from the cutting plane, the chains 9 rotating over two axes of rotation 10, 11 (see Fig. 2 ).
  • tips are attached to the chains 9, which can partially penetrate into a cut slice of material to be cut in order to hold it in such a way that the slices of material to be cut can be transported away by the chains 9.
  • the cutting machine also includes a storage racket, not shown, which can reach through the various chains 9 running parallel to one another and detach the slices of material to be cut from the tips, so that the slices of material to be cut can be placed on a storage surface 12 in a controlled manner (see Fig. 2 ).
  • the carriage 3 has a U-shaped cross section with a first, in Fig. 5 and Fig. 13 left boundary wall 13, which serves as a fixed system for the material to be cut, and a second, in Fig. 5 and Fig. 13 right boundary wall 14.
  • the boundary walls 13, 14 extend upwards from the support surface 4 and approximately in the direction of the axis of the cutting knife 1 or perpendicular to the cutting plane.
  • the cutting machine also has a displaceable contact bar 15, which extends above the support surface 4 between the boundary walls 13, 14 and parallel to them (see Fig. 1 , Fig. 4 , Fig. 12 and Fig. 13 ).
  • the contact bar 15 can be moved in the direction of movement of the carriage 3 due to a holder 17 that can be moved on a rod 16 (see Fig. 4 ).
  • a material to be cut can be held between the boundary wall 13 and the contact bar 15.
  • Fig. 3 the contact bar 15 is in a position shifted comparatively far to the left, in which it can hold a comparatively small material to be cut
  • Fig. 1 the contact bar 15 is shifted comparatively far to the right, so that it can hold a comparatively large material to be cut.
  • the leftover holder 5 has a plurality of holding elements 18, which are made of plastic or include plastic (see for example Fig. 6 to Fig. 11 ). These holding elements 18 are arranged next to each other at a distance from one another in the direction of movement of the carriage 3. The holding elements 18 extend perpendicular to the support surface 4 in the use position of the leftover holder 5. Furthermore, the holding elements 18 are arranged parallel to one another. The lower ends of the holding elements 18 form a comb-like structure which is open towards the support surface 4 in the use position of the leftover holder 5. The holding elements 18 each have a tip 19 at their lower end in the position of use.
  • the holding elements 18 are designed to rest against the material to be cut on the side of the material to be cut that is remote from the cutting knife 1 during the cutting process.
  • a plurality of tips 20 are arranged on the side of each of the holding elements 18 facing the cutting plane, which can partially penetrate into the material to be cut (see Fig. 7 ).
  • the leftover holder 5 comprises a rod 22 on which the holding elements 18 are held displaceably in the longitudinal direction of the rod 22 (see for example Fig. 8 and Fig. 9 ).
  • a spring 23 is arranged on the rod 22, so that the holding elements 18 can be displaced on the rod 22 against the force of the springs 23.
  • the leftover holder 5 also has a receptacle 24 in which the holding elements 18 are partially accommodated. Furthermore, the rod 22 is held on the receptacle 24 (see for example Fig. 7 ).
  • the cutting machine further comprises a swivel arm 25, to which the leftover holder 5 is pivotally attached.
  • the leftover holder 5 can stand up from the swivel arm 25 from a first position in which the holding elements 18 stand with their tips 19 on the support surface 4 (see Fig. 2 ), can be moved to a second position in which the leftover holder 5 is pivoted away from the support surface 4 (see Fig. 4 ).
  • the pivot arm 25 can be pivoted about an axis that extends parallel to the movable contact bar 15 or perpendicular to the cutting plane.
  • the leftover holder 5, together with the swivel arm 25, is parallel to the contact bar 15 or along an in Fig. 5 visible rod 26 can be moved. This allows the leftover holder 5 to be moved towards the material to be cut.
  • the contact strip 15 is provided with a chamfer 27 on its top (see Fig. 12 ), which makes it easier to swing past or push the holding elements 18 from above.
  • Fig. 12 shows the leftover holder 5 in a position in which one of the holding elements 18 just touches the chamfer 27 of the contact bar 15 with a flank 28 of its tip 20.
  • Fig. 13 shows the leftover holder 5 in a completely lowered state.
  • the contact bar 15 has pressed the two holding elements 18 apart in the slide feed direction or in the longitudinal direction of the rod 22. As a result, the distance 29 between these two holding elements 18 was increased so that the holding elements 18 could easily slide past the contact bar 15.
  • the second embodiment of the cutting machine comprises a residue holder 5 with a single holding element 18, which replaces the multiple holding elements 18 of the first embodiment of the cutting machine (see Fig. 14 and Fig. 15 ).
  • the holding element 18 has a flat part 18a in an upper region, which is formed from a particularly uninterrupted plastic surface.
  • the holding element 18 has in a lower region a plurality of parts 18b which are spaced apart from one another in the direction of movement of the carriage 3 and which are each connected to the flat part 18a arranged in the upper region.
