Description

The invention relates to a food slicing and / or dividing device, in particular for cutting or dividing bread, with the features of the preamble according to claim 1.

DE 37 06 485 C2 describes a tabletop bread slicer. In this case, a single drive is arranged in the lower part of the machine, which causes its knife and swing arm to penetrate from below through a bearing surface or cutting plate on which bread lies. A resulting wide kerf in the cutting plate must be covered with a kerf cover after each cut. The kerf cover is subject to great wear and tear and can cause noise.

A swing arm of such a bread slicing machine is mounted pivotably about a pivot point at a first end area and has a circular knife which is mounted rotatably about a pivot point on the second end area of the swing arm. A food cell that is open on all sides apart from the storage area on the underside is used to store the bread to be divided. A drive cell is formed below the bearing surface, in which the drive unit for driving the swing arm and the circular knife is arranged. By means of the drive unit, the swing arm is moved between a rest position and a cutting end position during the cutting process. In the rest position, the circular knife is covered by a hood-shaped section which is open at the bottom into the drive cell.
DE 1 231 396 A describes an industrial bread slicing machine in which a cutting arm is pivotably mounted above several parallel bread conveyor belts in order to make slices perpendicular to the transport direction. A circular knife, which can be set in rotation by means of a first motor and is designed for cutting bread, is mounted on the underside of the swing arm. The swing arm can be set in a pendulum motion by means of a separate motor and a crank mechanism, so that the circular knife is set in a pendulum motion together with the pendulum arm. Safe operation or use in the shop area of a bakery or retailer does not seem possible here.
GB 455 563 B discloses a bread slicing machine which, in the illustrated embodiment, is hand-operated, but can also be driven by means of an electric motor. By means of the manual drive, on the one hand a swivel arm is driven in a swivel movement and on the other hand a cutting knife is driven to rotate via a chain. The swivel arm and the cutting knife are arranged in a drive cell which is formed by the housing. The bread to be sliced is placed on the right on a feed plate and guided through a channel by means of an automatically operated thrust drive. The channel runs through the housing of the drive cell and is continued on the outlet side by side guides. The bread slices are guided on bars on the exit side. The upper pivot point of the swivel arm is above the bread storage plate.

The object of the invention is to provide an improved food slicing and / or dividing device, in particular for cutting and / or dividing bread, which is particularly low-noise and can work without covering the cutting gap.

This object is achieved by a food slicer and / or dividing device, in particular for cutting and / or dividing bread, with the features according to claim 1. Advantageous configurations are the subject matter of the dependent claims.

In particular, a food slicing and dividing device is thus provided, in particular for cutting or dividing bread, the device having: a swing arm that is pivotably mounted about a pivot point at a first end region, a circular knife that is pivotable about a pivot point at the second End region of the swing arm is mounted, a food cell for storing the food to be divided and a drive cell in which a drive unit for driving the swing arm and the circular knife is arranged, with the swing arm moving between a rest position, especially in the drive cell, and a cutting end position by means of the drive unit during the cutting process is pivotable in the food cell. It is advantageous that the pivot point of the swing arm is arranged above the pivot point of the circular knife, especially in the end position of the cut.

In other words, in such a cutting device, a first end region of the cutting or oscillating arm is mounted so as to be pivotable about a pivot point, which is in particular arranged within a drive cell. In the drive cell, which forms a particularly protected space opposite the outer space of the bread cutting device, at least part of the drive unit for driving the swing arm and the circular knife is arranged. As a result, at least some of the mechanical components of the swing arm that can be set in motion are advantageously arranged within a space that is protected from the outside space. At the other end of the swing arm, the rotatable circular knife is mounted, which is used to cut the food by means of the swing arm through the food cell and one located therein Food is pivotable. Since the circular knife can be pivoted by means of the swing arm at least during the cutting process through the food, individual components for driving the circular knife are conditionally arranged outside the drive cell between the two end sections of the swing arm.

Above the storage area for storing the food to be cut, a partition is arranged, which shields the drive cell and / or the or one motor cell from the cutting area of the food, the partition having a recess through which the swing arm moves from its rest position during the cutting process Drive cell can pass through to the cutting area.

Outside of the cutting operation, the swing arm can be swiveled back into its rest position, wherein the swing arm can in particular be designed so that it can be swiveled completely into the drive cell in order to be able to avoid injuries from components of the circular knife protruding into the food cell. The embodiment is particularly advantageous in that the pivot point of the swing arm is arranged above the pivot point of the circular knife, in particular during the cutting operation. Such an arrangement enables most of the components of the drive unit to be relocated to a space above the food to be cut, so that particles produced during cutting, for example breadcrumbs, cannot fall into the range of such drive components. This arrangement applies in particular to the cut end position. Independently of this, the pivot point of the circular knife in the rest position can optionally also be arranged higher than the pivot point of the swing arm in order to be able to pivot the circular knife as far as possible out of the food cell.

In the rest position of the swing arm, the swing arm lies above a bearing surface for storing the food to be cut, in particular in the rest position a central axis of the swing arm to the vertical at an angle in the range greater than or equal to 60 °, greater than or equal to 70 ° or greater or equal to 75 ° and is less than or equal to 100 °, 90 ° or 85 °, in particular from 60 to 100 °, 70 to 90 ° or 75 to 85 °.

It is thus emphasized that the swing arm can be pivoted backwards and upwards far enough to be able to pivot the second end area with the circular knife as far as possible out of the open area of the food cell. The further the pivoting takes place in the back and top direction, the larger the food cell can be made, or the further back and up or obliquely back and up a rear wall of the food cell can be formed without the circular knife through a slot in the rear wall protrudes into the area of the food cell or is to be protected laterally by appropriately designed protective wall sections.

Components of the drive unit for the swing arm and / or the circular knife are essentially above a bearing surface for storing the food to be cut.

In other words, the majority of the components of the drive unit are preferably located outside the food cell in the area of the drive cell and are thus protected against, in particular, particles which can get from the food cell into the area of movable components during the cutting process. This avoids contamination or even damage to the moving components of the drive unit. In addition, protection for the user of the cutting device is provided at the same time, since the user cannot or essentially cannot come into contact with movable components of the drive unit. In particular, the rotating circular knife during operation and possibly the swing arm with the circular knife set in motion components, for example a toothed belt, lead out of the space of the drive cell at least during operation, these also being located above the storage area for storing the food to be cut . A slot is expediently formed in the bearing surface through which the circumference of the circular knife is guided in order to be able to cleanly cut through the food down to its bottom.

The swing arm drive shaft ( 40 ) is above the bearing surface, but individual drive components and housing sections are also possible to extend lower.

In other words, the drive shaft in particular is located above the food to be cut. However, it is not ruled out that parts of the drive can also be located in a rear or possibly even underside area of the storage area, whereby these are then arranged spatially separated within the drive cell, in particular opposite the food cell, for example by partition walls.

The first end section is in every position in the drive cell. In the rest position, the second end section is at least partially within the drive cell and, in the cut end position, is guided out of the drive cell and pivoted into the food cell.

As a result, the first end section and the components arranged thereon are arranged protected from the food cell at all times. In the rest position, the second end section of the drive arm is also protected inside the drive cell and is only swiveled out of it for cutting. As a result, the components of the drive unit arranged on the second end section are also arranged in a protected manner in the rest position. In particular, the second end section can be pivoted so far into the drive cell that the circular knife is also arranged completely behind a partition or rear wall.

The swing arm forms a wedge-shaped extension on the side of the circular knife, which covers the circular knife on one side up to 90%, 80%, 70% or 60% in the longitudinal direction of the swing arm and / or which enters the cutting gap of the food to be cut during the cutting process and the Cutting gap is formed widening.

The swing arm itself or a section of it extends so far beyond the pivot or bearing point of the circular knife laterally along the circular knife that it covers the circular knife laterally beyond the pivot point and thus not only protects it, but also forms a wedge, which, due to the wedge-shaped configuration, expands the cut made by the knife in the food and thus causes the, in particular, cut-off slice of the food to be continued away from the cutting knife. At the same time, such an arrangement protects a large part of the circumferential surface of the cutting knife towards the side on which the cut-off part of the food is located.

The food cell has the storage surface for storing the food to be cut, the storage surface having a slot for inserting an edge region of the circular knife. The length of the swing arm from the pivot point of the swing arm to the outer end of the swing arm is shorter than the minimum distance between the pivot point of the swing arm and the top of the bearing surface, and / or a slot width of the slot is dimensioned so that only that Round knife can be inserted with a gap remaining on both sides, and / or the swing arm has a wedge-shaped extension which extends over a portion of the circular knife in such a way that the wedge section is not inserted into the gap during the cutting movement of the swing arm.

According to the first embodiment, apart from the blade of the circular knife mounted thereon, no components of the swing arm protrude into the slot. This solution also includes the case that even the circular knife does not protrude into the slot, although a clean separation of the food may then not take place up to its lower edge. The second embodiment emphasizes that only the circular knife can be inserted into the slot and has enough space on both sides so that it does not get stuck in the slot. In particular, the slot is made slightly wider than the width of the circular knife in order to be able to compensate for the pressure exerted by the food parallel to the axis of rotation of the circular knife and not immediately lead to the rotating circular knife jamming or hitting the edge of the slot. According to the third embodiment, it is emphasized that a separating wedge for separating the cut-off foodstuffs, in particular in each pivoted position, only projects up to a maximum of the top of the bearing surface, but does not also project into the gap.

A cutting residue collecting device is arranged below the food cell, the cutting residue collecting device being arranged in particular below the cutting knife slot in a storage area for storing the food.

Such a cutting residue collecting device is designed in particular in such a way that cutting residues can easily be removed from it after a cutting process or are already guided into an area outside the cutting device during cutting.

The drive cell has a swing arm cell in which the swing arm is mounted and arranged in its rest position, and has at least one motor cell in which a motor of the drive unit is arranged, and / or has a transmission cell in which at least part of the transmission is arranged to drive the pivoting movement of the swing arm and / or to drive the circular knife, the cells in the drive cell being separated from one another or largely separated from one another by at least one partition.

An optional design is thus emphasized in which the cutting device has different cells within its housing, which are subdivided by partition walls and thus enable particularly good protection of the movable components of the drive unit. At the same time, such partition walls also increase the stability of the entire arrangement and form fastening and bearing points.

The partition wall can be designed in particular in the manner of a rear wall which extends upwards from the support surface on the rear side. To components of the drive arm and in particular also In order to be able to fully accommodate the circular knife mounted thereon in the rest position, the partition wall can also extend obliquely towards the front, in particular over a section on the upper side.

The rocker arm or the rocker arm is mounted on a shaft which is mounted by means of at least two axially spaced apart bearings, the rocker arm being mounted on one end of the shaft that lies outside the at least two bearings.

This enables a mounting which prevents the circular knife from tilting during the cutting, even if there is lateral pressure from the food to be cut parallel to the shaft. In addition, the swing arm can be pivoted into a space at the rear of the housing in which there are no or only as few components of the drive and the motor as possible.

A machine designed in this way is, in particular, a table machine which has its drive essentially in the upper part. The swing arm is mounted as a knife swing arm in particular directly above the cut material. The knife rocker goes with the round or circular knife through the cut material, in particular on both sides to its pivot point. The knife rocker covers the knife on the left side in particular by 1/3 and is so narrow that the tapering facet causes a wedge effect during cutting and opens the cutting gap in the bread, so that lateral sticking to the circular knife is prevented. During the cutting process, the knife plunges into the cut material from above with a pendulum movement and pulls through a narrow slot at the bottom of the bread chute.

In particular, all bearing points in the transmission are ball-bearing on both sides. The power transmission on three axes takes place in particular with toothed and V-belts, which guarantee low-noise operation.

The three axes running in the transmission are designated as follows: One power transmission goes from the transmission drive shaft to the crankshaft and a second to the knife drive shaft. The drive to the circular knife goes at one end of the knife shaft.

The bread feed is electronically driven by a stepper motor.

1 shows an exemplary bread slicer 2 according to a preferred embodiment of a food slicing and dividing device. A front open housing 4th has two side walls starting from a bottom wall 10 which extend substantially flat upwards. On the top these are through a cover 12th connected with each other. On the back are the side walls 10 who have favourited cover 12th and the bottom wall is connected to a rear wall of the housing.

The front is in the bread slicer 2 a bread room 6th formed, which is formed essentially in the form of a horizontal V. An underside wall of the bread room 6th forms a storage area 8th which serves as a storage area for a food to be cut. The shelf is on the back 8th into a rear wall that runs essentially upwards and forwards 30th over, which first extends upwards and then obliquely upwards towards the front. This back wall 30th goes to the front into the top of the cover 12th above or attached to it. Front of the back wall 30th and on top of the shelf 8th is the bread-receiving area that is open to the front 6th designed as a food cell.

In the case 4th is in particular on the back of the rear wall 30th a drive cell formed. In particular, the drive cell is forward through the rear wall 30th the food cell, through the shelf 8th the food cell and optionally a front panel 16 delimited. The front panels 16 forms a transition between a front edge section of the storage area 8th and the bottom wall. The front panel shown as an example 16 is structured and points based on the shelf 8th an upwardly extending wall, then a front-side extending portion and then a first front-side downward portion, which in turn has an obliquely forward and downward portion, which has a downward-leading portion that finally connects to the front the bottom wall is connected or merges into this. In the forward sloping section of the front panels 16 operating elements are arranged, such as an input unit, for example 18th and an on / off switch 20th .

The case 4th thus has a frontally open food cell as the bread receiving space 6th and an area completely enclosed behind and below by walls. The completely enclosed area forms the drive cell, in which drive components of a drive unit are accommodated. For descriptive purposes in particular, the enclosed area can be subdivided into an upper head space 14th and an underside floor space 22nd . The headspace 14th extends to the rear of the rear wall 30th , underneath the cover 12th , on the front of the rear wall of the housing and between the side walls 10 . The headspace goes down 14th over into a rear upper section of the floor space 22nd . The floor space 22nd extends from there in the front direction below the storage area 8th up to the front panel 16 and above the bottom wall between the side walls 10 and the rear wall of the case.

Through the back wall 30th an upper slot extends from top to bottom 32 which in a lower slot 34 transforms. The lower slot 34 extends as a cutting knife slot from the rear through the storage area 8th in the front direction up to the front panel 16 . In particular, the lower slot extends 34 down to a slit process 52 , which is on the back in the front panel 16 the food cell is formed facing. Exemplary in the storage area 8th The passage openings shown serve as crumb passages 36 . These openings are used to pass the crumbs produced when a bread is cut through the shelf 8th to convey through down into a cutting residue collecting device, which in the floor space 22nd below the shelf 8th is arranged.

Stand feet are also shown 24 , which a spacing of the base plate or base wall to a base below the housing 4th enable.

2 and 3 show the arrangement according to 1 in a cut end position in which a cutting or swing arm 40 through the top slot 32 from the drive cell or from the headspace 14th is swung out towards the front. With its first end area is the swing arm 40 stored within the drive cell. At its opposite second end area 56 is on the swing arm 40 a circular knife 42 stored.

The cutting arm 40 consists of a one-piece or multi-piece circular knife rocker 44 educated. This consists, for example, of a guide plate 46 , which has the first end region and in the extended state or in the cut end position from the upper slot 32 protrudes downwards and slightly diagonally towards the front. The guide plate 46 protrudes with its lower edge area in the illustration on the right over a peripheral edge of the circular knife 42 out. On the left side of the guide plate 46 a wider body is arranged or formed. The wider body extends than the circular knife rocker 44 on the opposite side of the circular knife 42 further down and forms the second end area 56 of the swing arm 40 from which the circular knife 42 is stored. A knife shaft can be seen 102 , which extends in the right-hand direction from the circular knife rocker 44 extends and at the same time a pivot point of the circular knife or a centering 96 for the circular knife 42 trains.

The lower slot 34 is so wide that the circumference of the circular knife 42 through this in the direction of the floor space 22nd through the shelf 8th can dive through. The top slit on the back and top 32 is so wide that the circular knife is in its lower area 42 together with the circular knife swing arm 44 and the guide plate 46 through into the headspace 14th can be performed. Also is the top slot 32 Enlarged in a lateral area to allow a connecting rod to pass through 48 to enable.

The connecting rod 48 leads from the headspace 14th or the drive cell towards the front to one Point on the swing arm 40 , on which the front section of the connecting rod 48 is rotatably mounted. By moving the connecting rod forwards or backwards 48 is the swing arm 40 out of the case 4th can be swiveled out into the food cell or back into the head space 14th of the housing 4th pivotable.

4th shows in a sectional view on the right side the food cell or the bread receiving space 6th and on the left the interior of the housing 4th with the headspace 14th and the floor space 22nd . As walls of the housing 4th are the back wall on the left 82 , the bottom wall on the underside 104 and on top the cover 12th shown. The cover goes to the right or to the front 12th in the back wall 30th of the bread room 6th above. The back wall 30th extends first in the front direction, then forward and diagonally downwards, merges into an area leading downwards and extends down to the left before it enters the storage area 8th transforms. The shelf 8th extends in the underside and obliquely forward direction and finally goes into the front panels 16 above. After a course that first extends on the top and then extends on the front, this finally goes into the bottom wall 104 above.

It can be seen that the in 4th back or in 1 right side wall 10 extends further forward than the bread receiving space 6th and thus offers a lateral safeguard against inadvertent reaching into from the side.

To look in 4th A first partition extends transversely or from the rear to the front of the bread slicer 80 through the interior of the housing 4th . Through the partition 80 becomes the interior of the case 4th thus divided into different spatial sections transversely to its longitudinal direction. The partition 80 is used in particular to store components of the swing arm 40 and a drive unit.

At the top left is in the first partition 80 a bearing for a swing shaft 72 educated. Around the swing arm shaft 72 around is the swing arm 40 rotatable on the first partition 80 stored.

The first partition is on the top left 80 another bearing in which a crankshaft 62 is stored. On the crankshaft 62 is a crank wheel 60 non-rotatably attached. The crank wheel points near its circumference 60 a rod bearing 64 on, which is rotatable by the connecting rod 48 leads. With her swing arm 40 facing end is the connecting rod 48 via a driver 66 in an elongated hole 68 stored. The elongated hole extends over a short distance in one direction, which is essentially between the two end regions 54 , 56 of the swing arm 40 runs. One turn of the crank wheel 60 thus leads to the connecting rod 48 which is on the right side at the other end on the swing arm 40 is mounted, the swing arm 40 Forcibly guided in the rear or front direction.

For illustrative purposes, is the first partition 80 not completely continuous, but shown with a passage opening at the top on the left. This gives you a view of the rear of the first partition 80 arranged motor 84 Approved. The motor 84 preferably used to drive both the crank wheel 60 or from its crankshaft 62 as well as the rocker shaft 72 . Optionally, however, two motors can also be part of the drive unit in order to drive each of these shafts separately. One rotation of the rocker shaft 72 is transferred from this to a pinion 74 , which in turn is a toothed belt 76 drives. The timing belt 76 spans both the pinion 74 as well as a corresponding pinion on the knife shaft 102 and transmits a rotary motion to the rocker shaft 72 on the circular knife 42 .

5 shows the components 4th in the rest position, in which the crank wheel 60 its rod bearing 64 has adjusted to the far left. This is the swing arm 40 together with the circular knife, not shown for illustration purposes, in the head space 14th drawn into it.

6th shows a corresponding view with the crank wheel 60 , its rod bearing 64 is adjusted on the right so that the swing arm 40 is in the cut end position.

7th shows essentially the components of the above 4th to 6th , but this from the opposite side view. A second partition is shown 88 which extends parallel and at a distance from the first partition wall through the interior of the housing 4th extends. Front of the second partition 88 is the engine 84 arranged, which a transmission arranged on the underside 86 drives. Top left is in the second partition 88 the second shaft bearing 90 with the rocker shaft 72 outlined.

8th shows the components according to 7th but with the circular knife removed. Can be seen in the second end area 56 of the swing arm 40 the knife shaft stored in this 102 . A knife pinion sits on this 94 to which the timing belt 76 is led. The timing belt 76 leads through a belt box 92 , which in the wall of the circular knife rocker 44 is let in.

9 and 10 show the drive components independent of the housing components. The two partitions are shown 80 , 88 . The partition walls are on the back 80 , 88 connected to each other or through the rear wall of the housing and thus form a stable U-profile. On the right side of the second partition 88 are the engine 84 and the transmission 86 arranged. A gear shaft leads from the gearbox 108 through the two partitions 88 , 80 through. By means of the gear shaft 108 of the transmission 86 are about suitable pinions of the toothed belt 76 and a timing belt 106 to drive the crank wheel 60 drivable.

It can be seen that the guide plate 46 in its underside section has a recess into which an upper section of the circumference of the circular knife 42 leads into it. The circular knife swing arm 44 extends into the space on the left and forms a wedge-shaped extension in its lower section 70 out. The wedge-shaped extension 70 is on the front, that is, in the pendulum direction out of the housing 4th out, narrow and widening towards the rear. The wedge-shaped extension 70 penetrates you through the circular knife 42 a gap formed in the food and moves the left-hand cut slice of the food away from the rest of the food.

11 shows a view of the drive components from the left in the direction of the second partition 88 . In particular, the gear shaft is shown 100 , which is mounted in the two partition walls 80, 88 and the two pinions 110 , 112 drives. The pinion 110 , 112 are from the timing belt 76 or. 106 encompassed, with the timing belt 76 , 106 the crank wheel 60 or the pinion 74 encompass. By choosing a suitable diameter of the pinion 72 , 110 , 112 and the crank wheel 60 are the rocker shaft 72 and the crankshaft 62 can be driven relative to one another in a desired ratio.

Left of the first partition 80 is a swing arm cell 114 formed in which the swing arm 40 is stored and arranged in its rest position. In at least one transmission cell 116 and / or motor cell 118 are the drive components such as the pinion and toothed belt 76 , 106 or the engine 84 arranged with the gearbox. The drive cell is thus in particular made up of the transmission cell 116 and the engine cell 118 educated.

Components are not shown, such as a control unit which, after inserting a foodstuff to be sliced and actuating the input unit accordingly 18th controls a program to cut the food. Next to the engine 84 for moving the circular knife 42 In the rotation and in the pendulum movement, a transport mechanism can thus also be driven, for example, which gradually transports the food to be cut and / or cut parts of the food to the left for cutting.

In particular, in the case of the exemplary embodiment that is modified compared to that, individual components can be replaced by components that have the same or comparable effect. Instead of pinions and toothed belts, it is possible, for example, to use gear rods or worm drives. You can also use the crank wheel 60 and the rocker shaft 72 or the circular knife driven above 42 be driven by two motors instead of just one motor.

Components such as a cover or hood that can be pulled in front of the food cell can also be provided.
