Definitions

  • the invention relates to a device for cutting bread according to the preamble of claim 1.
  • Such machines are known. They are mostly used in bakeries to offer customers freshly cut bread.
  • a known type of bread slicing machine works with a circular blade, which circulates circularly by means of an eccentric and in this case emerges from a cutting gap in each case cuts off a slice of the slowly continuously or clocked forward pushed bread and then dips back into the cutting gap.
  • the sliced bread can be taken out of the machine and placed on a so-called tongue to put a bag over the disc package.
  • the DE 10 2008 003 603 U1 discloses a bread slicer in which the loaf of bread is withdrawn during a cutting operation to reduce the pressure on the circular blade. Thus, the risk of the loaf sticking to the knife is reduced.
  • a disadvantage of the known bread slicing machines is that the uniform removal of the sliced bread slices away from the knife is not optimally guaranteed.
  • a known solution proposes to provide an inclined plane in the discharge section, on which the cut slices slide away from the knife. However, such removal is not reliable to the extent desired.
  • the pushing device which pushes the bread to be cut to the knife and presses the last sliced bread slice through the currently exposed bread end face by the distance of the thickness of the next slice to be cut in the Aburerabites, in addition to this to press the slice of sliced last still further into the discharge section, in order to prevent a backlog on the knife.
  • this additional pushing distance can be different lengths.
  • the bread to be cut is drawn again in the direction of the feed section, until only one bread section of the thickness to be cut is in the discharge section and then the next cut can be carried out.
  • the bread can be withdrawn by the feed according to the invention by an additional distance by more than this distance and then pushed back a little bit forward so that then a slice of the desired thickness d is cut off. This may benefit a more uniform thickness d of the slices cut in succession.
  • the pusher accordingly performs - controlled by an electronic control - an oscillating motion by first travels a feed path v in the feed direction, which is composed of the slice thickness d and the additional path x (the additional thrust path), and the subsequent, in the opposite Direction traveled distance of the size x or a slightly larger distance x + s with subsequent feed to the distance s.
  • the net feed path corresponds to the disk thickness d, so that in this positioning of the bread a disk of thickness d can be cut off.
  • the invention thus makes it possible that the pusher between two cutting operations pushes the uncut bread over the cutting plane so that it pushes at least the last sliced bread slice, preferably all previously cut slices in bread advance direction.
  • the cutting plane of the knife is used as a reference for the pushing distances, since the circular blade does not form a precise reference because of its finite dimensions.
  • a further development of the invention is characterized in that the two cutting operations in which the pushing device only moves the cut surface of the bread back before and then again follow one another. This ensures a steady feed of the disc package after each cutting operation.
  • the additional feed i. in addition to the feed to the slice thickness d, triggered, but for example only after every second cut.
  • Other variations, even within the cutting of a bread are possible. For example, it may be provided that during the cutting of the second half of the half, the additional pushing movement is carried out more frequently than during the cutting of the first half of the half, since more thrust has to be applied the more slices have already been cut off.
  • the additional thrust travel x is advantageously at least 2 mm, preferably at least 4 mm, preferably at least 6 mm.
  • the total feed travel v measured from the cutting plane of the knife so at least 2 mm plus the predetermined slice thickness d or preferably at least 4 mm plus the slice thickness d, etc.
  • the pushing distance at the end of the entire cutting process beyond the cutting plane can be several centimeters depending on the bread length and design of the device.
  • the pushing distance t can be automatically calculated in advance by determining the bread length in the device by means of appropriate measuring means (optical, stop sensors such as buttons, etc.) and calculating the distance t from the measurement results and following the cutting.
  • the thrust device according to the invention on fixing means to fix the bread at the knife distal end and advance the bread against the knife.
  • the fixing means preferably comprise an upwardly and upwardly pivotable claw, which is inserted before the start of the cutting operation at the knife-distal end of the bread and released after the end of the cutting process of the last disc.
  • the fixing means are preferably arranged on a displaceable arm, which in turn is advantageously displaceable along a rail in and against the bread feed direction.
  • This embodiment is easy to implement; a stepper motor with reversal of direction can be used without further ado.
  • an essentially vertically extending, rigid wall protrudes on the edge of the bottom of the discharge section facing the knife.
  • the upper edge of the wall runs along the bread slice width at the same height or below the bread support surface of the soil of the feed section.
  • the upstanding from the bottom of Abcomrabitess wall prevents the lower disc portion of the last cut and now on the bread slab - ie before advancing the loaf to the beginning of the next cut - is pushed back from the previously cut slices against the knife.
  • the subsequent push through the loaf of bread then carries the disk pack away from the wall so that a clean cut and remove process is achieved.
  • the subsequently cut disc then has enough space to be separated unmolested from the previously cut from the loaf of bread.
  • the additional feed of the thrust device supports this process and helps to avoid backflow between the disk pack and the wall.
  • the rigid wall is formed integrally with the bottom of the discharge section. It is preferred in this case if the rigid wall forms an upwardly bent portion of the bottom of the discharge section.
  • the thickness of the wall is preferably less than that of a bread slice having a normal thickness of 8-12 mm.
  • the wall thickness is advantageously less than 5 mm, preferably less than 3 mm, so that the cut disc does not fall on the top wall, but in the space between the previously cut disc and the wall.
  • the wall has proved to be advantageous if the wall has a height of 5 mm to 20 mm, while the height difference between the surfaces of the two floors is between 5 mm and 25 mm. In this case, the height difference between the bottom of the feed section and the bottom of the discharge section is measured.
  • the device according to the invention has an end stop for the first-cut disc in the discharge section, which is mit psychologist so that this disc is always applied to the end stop.
  • the end stop is moved in accordance with the Brottransporttakt, the distance of the end stop per clock is preferably slightly larger than the distance the bread travels (net) per bar. This takes into account the greater extent of the disc package in the thrust direction compared to the uncut state.
  • the invention also relates to a method for cutting and transporting bread in a bread-cutting device, this device having the aforementioned features.
  • the method of the invention after cutting one slice at a time, the bread is advanced by more than the slice thickness to further push the slice (s) already cut into the discharge section. Subsequently, the uncut bread is withdrawn again until it protrudes into the Abrrab bainsky only one slice thickness. Then the knife can cut off the corresponding disc.
  • the remaining bread which is no longer to be cut is pushed over the cutting plane until the bread slice package is pushed together between an end stop on the knife-distant side and the said remaining bread such that it is subsequently removed manually from the device or from a lifting table can still be driven up.
  • the claw is only pulled out of the last disc when the disc package is pressed together.
  • the end of the bread rests against the adjacent slice of bread with such high friction that it is not carried along by the claw. This thus allows easy automatic release of the claw from the last slice of bread.
  • the bread is not just with a claw or similar. held, but also on its upper side circumferentially, preferably held transversely to the thrust direction of the bread.
  • FIG. 1 schematically shows a plan view of the device 1 with a housing 2, in which in particular a feed section 3 and a discharge section 4 are provided and which can be closed by a hood 17.
  • the feed section 3 comprises a preferably made of stainless steel bottom 8 with a flat receiving surface on which the bread B to be cut is placed.
  • a claw 22 which can be pivoted up and down, is coupled with three tines on a push arm 23, which runs perpendicular to the pushing direction (see arrow P) of the bread B (see also further details in FIGS Figures 3-6 ).
  • the push arm 23 and with it the claw 22 are motor driven (motor not shown) along a in the direction of thrust (arrow P) extending, linear rail 24 movable to push the bread B in the direction of a circular blade 14.
  • the push arm 23 is moved back to its original position (the two movements are indicated by the double arrow in FIG. 1 indicated).
  • FIG. 1 three different positions of the push arm 23 are shown: In solid lines, the initial position is shown, while a middle and the end position after completion of the cutting process are shown in dashed lines.
  • the claw 22, the push arm 23, the rail 24 and the feed motor are parts of a pusher 21 for transporting the bread B from the feed section 3 to the knife 14.
  • the claw 22 is stored in a cuboid claw housing 25 (in FIG. 1 omitted for clarity), on its side facing the bread B openings (not visible in the side view) for each prong of the claw 22 has. Through these openings, the tines occur when the bread is gripped before cutting begins (see double arrow in FIG. 3 ).
  • the claw 22 is further provided with a shaft 26 (also not in FIG FIG. 1 shown), which runs parallel to the push arm 23 and by means of an engine, not shown, the claw 22 is able to pivot connected.
  • the gripping end detected by the claw 22 lies partially, a lower recess of the claw housing 25 penetrating, in the claw housing 25, whereby it is even better fixed. Also, the upper edge of the recess holds the so fixed fixed end of the bread when the claw 22 is pulled out of the bread end after completion of the cutting process.
  • the circular blade 14 moves in a vertical cutting plane 13 and, when circulating out of a gap 16, which separates the feed section 3 from the discharge section 4, out and back into this.
  • the cutting plane 13 is used in the present case as the reference location for the pushing distances of the claw 22 or of the bread B to be described, since the circular blade 14 naturally has finite dimensions, including a mostly non-linear cutting bevel, and thus does not represent an exact reference.
  • the circular blade 14 is mounted eccentrically about a shaft 15 and is driven by a motor 19 controlled by a controller 20. It is in the FIG. 2 three different positions of the circular blade 14 are shown by way of example, two of them with dashed lines. In particular, it can be seen how the circular knife 14 is able to cut the bread B into slices.
  • the exact eccentric mechanism is not shown; However, the skilled person is familiar with corresponding constructions. In the present case, they are not essential to the invention.
  • the discharge section 4 comprises in the illustrated embodiment, a bottom 5, which preferably consists of stainless steel and as well as the bottom 8 is inclined with respect to a horizontal plane to the machine front 1a towards (s. FIG. 2 ; in FIG. 1 not shown).
  • a side support 9 for the bread slices S projects in the region of the front edge of the base 5.
  • the side support 9 is presently inclined relative to a vertical plane to the front side 1 a (s. FIG. 2 ).
  • Support surface 5 and side support 9 are in this case substantially to each other perpendicular.
  • the feed section 3 has a corresponding side support 10, which runs in the same plane as the side support 9 (see FIG. Figures 1 and 2 ).
  • a pneumatic cylinder 18 is shown with which the hood 17 can be opened and closed.
  • the pneumatic cylinder 18 is presently connected to the controller 20 (details not shown), for example, to open the hood 17 when the cutting operation is completed. When the knife 14 is running, however, the hood 17 can not be opened.
  • the first cut slice S falls against the end stop 28, which thus ensures the cohesion of the disc package.
  • the end stop 28 is shown at the end of the cutting process.
  • the double arrow in the discharge section 3 signals that the end stop is moved close to the knife 14 before the first cutting.
  • the bottom 5 is bent towards the blade 14 upwards, so that a wall 6 is formed, which runs parallel to the circular blade 14 and - when slicing - from this a horizontal distance of at most a few millimeters (s , FIGS. 3 and 4 ).
  • the height of the wall 6 is presently about 5-20 mm.
  • the wall thickness is - when integrally with the bottom 5 - depending on the choice of the stainless steel sheet of the bottom 5 preferably about 2-3 mm.
  • the upper edge 7 of the wall 6 is located either at the height of the bread support surface of the Bottom 8 or below. In the latter case, a horizontal gap between the upper wall edge 7 and the underside of the bottom 8 may be formed, which are arranged laterally offset from each other, ie in the horizontal direction.
  • the rigid and firmly connected to the bottom 5 wall 6 prevents the last cut slice S is urged in the direction of the gap 16. This is not necessarily the case, but can, if occurring, interfere with the operation of the cutting device sensitive.
  • the disc S is pressed in such a case against the wall 6 and can be supported laterally here. Thus, this slice S can not get in the direction of the loaf B nor in the cutting gap 16. It is thus guaranteed a safe and fast cutting sequence.
  • the length of the wall seen in the cutting direction is expediently at least as large as the largest breadths that are to be cut with the device according to the invention. But this is not mandatory; even shorter lengths can serve the same purpose.
  • the pushing device 21 is designed in such a way that, on the one hand, it can advance and retract the loaf B between two cutting processes, which are not necessarily consecutive.
  • the pushing device 21 can push together the cut slices S in the discharge section 4 after cutting the entire bread B.
  • FIG. 3 It is shown how the circular knife 14 - controlled by the controller 20 - just cuts a slice S from the loaf of bread B.
  • the knife 14 emerges from the gap 16 and penetrates from the top into the bread loaf B.
  • the disc S inclines slightly to the discharge section 4 and then falls in the gap of length z, which is formed by the previously cut slice S and the wall 6. There it stands the last cut off slice S, by the cutting and the dropping possibly slightly inclined, on the bottom 5 ( FIG. 4 ).
  • the pushing device 21 now pushes the loaf B a distance v in the direction of the discharge section 4 (see arrow V in FIG. 5 ).
  • the knife 14 is meanwhile submerged in the gap 16 again.
  • the feed distance v is greater by the distance x than the predetermined slice thickness d (s. FIG. 5 ).
  • the already cut slices S are also advanced in the direction V, in an ideal system also by the distance x, which is usually several millimeters (for example, 8-12 mm). Since the disc package naturally has a greater length than in the uncut state, only the pushing distance v of the bread can be precisely defined. It is essential, however, that between the last sliced slice S and the uncut bread B, a gap arises which is sufficiently larger than the machine predetermined slice thickness d, which was entered by a user or set in the machine.
  • the large feed to the distance v serves to ensure a safe, unrestricted ejection of the subsequent disc S without other means of transport (inclined plane in the thrust direction, additional vibrators in the discharge area, other active devices for wheel transport, etc.) would be necessary - but can be present.
  • the bottom 5 can in particular in the thrust direction V extend horizontally, as in the Figures 3-6 shown.
  • the wall 6 also still needs to be bridged by a just cut slice S, so that they in the space of length z (s. FIG. 3 ) can fall.
  • the additional feed path x is thus in the present case, suitably greater than the thickness of the wall 6 plus the distance of this wall 6 of the knife 14, which can be 3-4 mm in total. In this way it can be ensured that the slices S are transported away safely and quickly, including avoiding jamming of sliced bread slices in the gap 16.
  • the loaf B is pulled back by the distance x with the aid of the push device 21 (see arrow R in FIG. 6 ), so that the bread B projects beyond the slice plane 13 only by the slice thickness d. Now, a disc S of such thickness d can be cut as in FIG. 3 is shown. This completes a cutting cycle.
  • the known cutting devices push the bread B only by the predetermined slice thickness d, in order then to cut off the next slice S. There are often appropriate tools necessary to create enough space for the next disc.
  • the FIG. 1 shows in its left half in dashed lines the complete disk package.
  • the inventively designed pushing device 21 pushes the last, still held by the claw 22 last disc on the cutting plane 13 against the other slices S until the disc pack between the end stop 28 and the last loaded disc is compacted, so no significant gaps between the individual discs S are present.
  • the push distance t which is covered by the arm 23 and the claw 22 (also shown in dashed lines), can be several centimeters, but also smaller.
  • the pushing distance t may have been automatically calculated in advance, in particular by automatically measuring the length of the bread to be cut in the device by means of corresponding sensors and calculating the pushing distance t on the basis of the measuring results.
  • the pusher 21 can be moved as the disks S are pushed together, both in the opposite direction of the movement of the claw 22 or in the same direction as the claw 22. In the latter case, the claw must of course to go a long way.
  • the discs S are compactly compressed and then - after preferably automatic, controlled opening of the hood 17 - comfortably as a whole, i. without even having to push the discs together, are removed from the discharge section 4.
  • a lifting table is provided, which lifts the disk package out of the discharge section 4, so that the operator does not have to bend into the discharge section 4.
  • the compaction described above also serves in this case for positioning the disk package so that no disks of a loose disk package fall from the lifting table back into the discharge section.
  • the claw 22 can be pulled out of the last disk S, without this disk is entrained, since this remains due to the friction in the disk package.
  • This mechanism also works in the event that no pivotable claw is used, but, for example, a horizontally movable claw or fork.
  • the recess in the claw housing 25 prevents the bread end being taken by the claw 22 when it is pulled out.
  • the invention is not limited to the illustrated embodiment. Modifications within the scope of the claims are possible at any time. So it is z. B. not absolutely necessary to realize the additional thrust to the feed path x after each cut. By way of example, only after every second or third cut can the pusher 21 effect the additional feed x. Further modifications of the additional feeds with regard to the times of thrust and stroke lengths in relation to the cutting times, the stroke length are readily within the scope of this invention. Thus, for example, it is possible that the pusher 21 realizes a non-constant additional feed x, ie the feed path v varies, for example as a function of the remaining amount of bread to be cut. For example, the path x may become larger as the remaining length of the bread decreases. Also, for the inventive designed pushing device 21 additional transport facilities for the bread and / or slices in the invention possible, with both passive and active means of transport in question (in the FIG. 2 shown inclined plane is a passive means of transport).
