Definitions

  • the invention relates to a bread slicing machine for slicing a loaf of bread, which has a machine housing which accommodates a drive motor and a cutting knife, which is driven by this, is held on a knife arm, rotates in a cutting plane and / or is movable in a circumferential manner, with a feed shaft for introducing the loaf of bread to be sliced in the bread slicer, with a receiving shaft adjoining the feed chute except for a knife gap for receiving all slices of the sliced loaf of bread, as well as with a feed plate on which the loaf of bread inserted into the feed chute rests at the front and which has a gripper provided with claws for holding the loaf of bread , wherein the connection axis of the feed chute with the receiving chute is arranged inclined to the vertical by at least 30 °.
  • bread slicing machines are known with a gripper for moving the loaf of bread and a counter holder opposite the gripper on the loaf of bread, which holds the bread slices of the sliced loaf in their position.
  • the counter holder must be moved in a synchronized manner with the gripper.
  • the gripper is located in a loading area, in which the user places the loaf of bread. The gripper must therefore always first be removed from the loading area in a time-consuming manner before the loaf of bread is inserted.
  • the slice pack is pushed from the cutting area through an opening in a wall of the machine housing of the bread slicing machine onto a holding device, usually automatically.
  • a circular knife moves through the slot and cuts a piece of bread at the level of the slot, creating slices of bread below the slot.
  • An offset is formed between the shaft areas, which can be reduced by moving the shaft areas relative to one another.
  • the first chamber is arranged above the second chamber.
  • a support surface supports the bread in the first chamber.
  • a movable pusher in the first chamber conveys the bread in the direction of the second chamber, the displacement taking place essentially vertically.
  • the pusher has hooking means for holding the bread against the action of gravity.
  • a detector detects the proximity of the bread to the slide, whereby the hooking means can then be extended. After cutting, the bread is returned to the first chamber.
  • this known bread slicer requires a support to support the cut slices of bread and is therefore comparatively complicated structure. After the bread has been conveyed back into the first chamber, the slide is removed in a time-consuming manner in order to be able to remove the bread from the first chamber.
  • a cutting machine in which a loaf of food, usually a loaf of bread, is guided past a cutting disk in a shaft slightly inclined to the vertical from top to bottom in a non-severed state. The length of the food loaf is determined. The loaf is then conveyed from bottom to top in the shaft and is cut into slices by the cutting disc.
  • This embodiment of a bread slicing machine is also structurally complex and has a closure plate and a holding plate, between which a loaf of bread to be sliced is arranged.
  • a holding plate is also required here in order to hold the -whole or partially sliced- loaf of bread in its-almost vertical- position.
  • the holding plate has to be moved back into its starting position in a time-consuming manner before removing a loaf of bread from the shaft and after inserting a new loaf of bread in order to give the loaf of bread space.
  • Reference [0] discloses a bread slicing machine with the features defined at the outset, in which the receiving shaft is arranged in the vertical direction below the feed shaft. The end position of the transport slide is in front of the slot into which the circular knife can be inserted, viewed in the conveying direction. The transport slide according to reference [0] is therefore not designed to be moved over the slot. Reference [0] also mentions claws on the transport slide, which are intended to stick sufficiently firmly into the end of the food strand, but no defined movement control of the same. Reference [0] also does not disclose a control which brings about a transport of the uncut loaf of bread placed in the receiving shaft into the transport shaft. Object of the invention
  • the present invention is based on the - viewed in detail, relatively demanding - task of designing a generic bread slicing machine with the features listed above in a structurally simple and material-saving manner such that a stable cutting process can be carried out in a time-saving manner.
  • the present invention in a surprisingly simple and effective way in that the receiving shaft is arranged in the vertical direction above the feed shaft, that the feed plate can be moved from an end of the feed shaft facing away from the receiving shaft to over the knife gap and back again, and that an electronic control device is provided which is designed to cause the claws of the gripper to extend and engage in a front-side fixing section, which is extended in the direction of the connecting axis, of a loaf of bread introduced into the feed shaft, and then to transport the as yet uncut loaf over the Knife gap into the receiving shaft, the control device automatically causing the cutting knife to move multiple times into the knife gap during transport to cut off one slice from the loaf of bread and then the Cutting knife moved completely out of the knife gap again in order to enable further transport of the cut slice into the receiving shaft as well as the remaining, still uncut loaf of bread via the knife gap.
  • the electronic control device is specially designed to transport the uncut loaf of bread from Receiving shaft past the cutting knife, which is removed from the knife gap, that is, as a rule, moved out into the feed shaft and then controlling a return transport of the loaf of bread to be sliced from the feed shaft into the receiving shaft.
  • the rotating cutting knife is moved into and out of the knife gap in such a way that the loaf of bread is sliced into slices that are parallel to one another.
  • the loaf of bread is first placed in the receiving shaft, then conveyed into the feed shaft and finally transported back into the receiving shaft, the loaf of bread being cut into slices on its return transport.
  • the receiving shaft is arranged in the vertical direction above the feed shaft. Due to the inclination of the connecting axis of the feed shaft with the receiving shaft by at least 30 °, in particular about 45 °, but not more than 60 ° from the vertical, the loaf of bread is held in its position by the receiving shaft in the feed shaft during the cutting process and prevents the sliced one from falling over Loaves of bread counteracted without - as before - an additional counter holder is necessary, which is moved by the closure plate and the loaf of bread or is shifted synchronously in another way parallel to the closure plate. This means that no time-consuming movement of the counter holder is necessary after the cutting process.
  • the bread slicing machine according to the invention Due to the inclination of the connecting axis of the feed chute with the receiving chute, the bread slicing machine according to the invention also has a comparatively small base area in relation to known arrangements.
  • the electronic control device can increase the stability of the slicing process, for example by setting a suitable transport speed of the loaf of bread during the slicing process and regulating it accordingly.
  • the electronic control device is preferably also designed to transport the uncut loaf of bread from the receiving shaft into the feed shaft past the moved cutting knife removed from the knife gap and then transport the loaf of bread back from the feed shaft into the receiving shaft, and then during the return transport
  • the cutting knife is moved into and out of the knife gap in such a way that the loaf of bread is sliced into mutually parallel slices.
  • the loaf of bread is in particular placed in the receiving shaft, conveyed into the feed shaft and then transported back into the receiving shaft, the loaf of bread being cut up during the return transport.
  • the bread slicing machine according to the invention is preferably designed in such a way that the receiving shaft at its end facing the feed shaft is parallel to the cutting plane and has approximately the same width as the feed shaft in this area. This enables better support for the loaf of bread on the transition from the feed chute to the receiving chute.
  • Another embodiment of the bread slicing machine according to the invention is characterized by a counter holder which can be arranged on the loaf of bread opposite the feed plate.
  • the counter holder also prevents the loaf of bread that has already been cut from falling over.
  • the bread slicing machine is preferably designed in such a way that a connecting axis of the feed chute with the receiving chute is arranged inclined relative to the vertical, preferably by approximately 45 °.
  • the oblique alignment prevents the sliced loaf of bread from falling over.
  • the bread slicer can be designed with a smaller footprint than with a horizontally aligned feed chute. With such a Transporting the loaf of bread, there is also no need for a counter holder opposite the feed plate, which is intended to prevent the bread from tipping over and which is moved by the feed plate and the bread or is shifted in some other way parallel to the feed plate. Such a counter holder would generally first have to be removed when the bread is inserted.
  • Embodiments of the invention have further advantages in which the knife arm is designed to move the cutting knife on a curve, preferably a circular curve. This enables a periodic retraction of the cutting knife into the loaf of bread, with vibrations in the bread cutting machine being reduced.
  • Embodiments of the bread slicing machine according to the invention are particularly preferred, which are characterized in that the receiving shaft is formed by two sheet-metal sections which are angularly adjacent to one another and which together are L-shaped in cross-section.
  • the loaf of bread is supported on two sides by the L-shape.
  • One class of advantageous embodiments of the bread slicing machine according to the invention is characterized in that a cover of the machine housing can be moved in a rotary movement on a guide rail. This enables a space-saving, compact and simple design of the opening mechanism for the bread slicing machine.
  • these embodiments are preferably designed in such a way that the cutting knife, in a non-activated state, is arranged outside the knife gap in the bread slicing machine so that it cannot be touched from outside the cover of the machine housing.
  • the receiving shaft is arranged in such a way that an uncut loaf of bread can be placed by a user on a collar section of the receiving shaft designed as a pocketing aid before the cutting process, and that the slices of the sliced loaf of bread can be removed from the collar section by the user, preferably after the cutting process Slipping over a bag-shaped packaging means are removable. This enables a particularly space-saving design of the bread slicing machine.
  • the receiving shaft designed as a pocketing aid is arranged with the cantilever portion within a cover of the machine housing, so that the bread slicing machine according to the invention can be made more compact and significantly less bulky in a structurally simple and material-saving manner. Furthermore, after the cutting process, the sliced loaf of bread does not have to be moved into the area of the pouching aid by means of a shifting process. In addition, such a configuration offers increased protection for a user against inadvertent intervention in the bread slicer.
  • the tucking aid integrated in the machine housing does not protrude from the machine housing and thus on the one hand widens the space required by the machine and on the other hand there is no longer the risk of a person passing by the machine getting stuck on it.
  • the bagging aid is located inside the machine housing, which ensures a space-saving design for the bread machine.
  • the access from inside the bread slicing machine to the pouching aid does not have to be secured separately, which means that structural components for the bread slicing machine can be saved.
  • the protection for the user of the bread slicer increases significantly, since only one access to the bread slicer has to be secured.
  • the bread slicing machine only has a single hood for closing a cutting area in which the loaf of bread is cut.
  • the external dimensions of the feed chute in directions parallel to the cutting plane should be greater than or equal to the maximum external dimensions of loaves of bread to be sliced in these directions.
  • the outer dimensions of the cantilever section in directions parallel to the cutting plane should also be selected to be smaller, at least at a free end facing away from the feed chute, than the outer dimensions of the feed chute in these directions.
  • such a modified bread slicing machine according to the invention with the receiving shaft has an area of the bread shaft into which a user of the bread slicing machine inserts the loaf, the bread shaft including in particular the receiving shaft and also the feed shaft. This is also the area from which the user removes the sliced loaf of bread.
  • a support plate designed as part of the receiving shaft or as the entire receiving shaft is thus at the same time an output plate from which the user can conveniently remove the sliced loaf of bread.
  • a pouching aid can, in particular, be a holding plate for the loaf of bread, which as a rule does not protrude far beyond the bread loaf in width or is even less wide than the loaf of bread.
  • This holding plate is openly accessible on a narrow side, so that the user can put a packaging means, in particular a bag, over the loaf of bread as long as the loaf of bread lies on the pouching aid.
  • the user moves the bag longitudinally along the longitudinal axis of the loaf of bread.
  • the dispensing tray is designed as a pouching aid.
  • the bread cutting machine has a shorter and a longer side, an input device for the electronic control device and the cantilever portion being accessible to a user from the shorter side of the bread cutting machine.
  • This is particularly advantageous when the bread slicer is in the self-service area of a supermarket should be set up in a space-saving manner.
  • the bread slicer is oriented between shelves so that the shorter side of the bread slicer runs parallel to the direction along the shelves, while the longer side of the bread slicer is oriented toward the depth of the shelves.
  • the longer side of the bread slicing machine can be designed to be shorter when the feed chute and receiving chute are aligned at an angle than in a bread slicing machine in which the feed chute and the receiving chute are installed horizontally.
  • Embodiments of the invention are also particularly preferred in which through-slots are formed in the feed chute for breadcrumbs to fall through. This makes it easier to clean the feed chute. In particular, the breadcrumbs fall out of the feed shaft through the through slots during the cutting process.
  • very particularly advantageous embodiments of the invention are characterized in that a distance is formed between the feed plate in its state in which it is at the maximum moved away from the receiving shaft and the feed shaft. This serves to simplify the cleaning of the feed chute.
  • a crumb crate is arranged below the feed plate or the feed chute, which crate in particular has a deflector plate.
  • the crumb box is used to collect the breadcrumbs produced during the cutting process.
  • the deflector plate is aligned in particular, starting from the edge of the crumb box, at an angle to the outside, in order to catch as many falling breadcrumbs as possible and to direct them into the crumb box. Due to the vibrations that always occur during the cutting process, the breadcrumbs fall mainly into the crumb box and do not remain in the feed chute or receiving chute. In this way, the feed chute and the receiving chute are cleaned quasi mechanically and automatically during the cutting process itself.
  • Embodiments of the bread slicing machine according to the invention are also advantageous in which the extendable claws of the gripper are geometrically designed in shape and expansion in such a way that the length of the end-side fixing section of the front-side loaf of bread placed in the feed shaft is at most twice the thickness of the later slices to be cut, preferably the same thickness as the slices. This brings about a uniform thickness of the fixing section and of the disks for easy handling of the fixing section when it is consumed.
  • the engagement height of the claws of the gripper which corresponds to the length of the front fixing section in the direction of the connecting axis, is between 10mm and 40mm, preferably 20mm to 30mm. With this length, the fixing section can be conveniently handled when it is consumed.
  • a detection device which, in an operating state when the loaf of bread introduced into the feed shaft is moved by means of the feed plate in the direction of the cutting knife inserted into the knife gap, can detect when the loaf of bread is on the cutting knife strikes, the detection device in particular comprising a pressure sensor preferably attached to the feed plate or a light barrier or a device for measuring the current current through an electric drive unit moving the feed plate or a device for measuring the current electrical resistance between the feed plate and the cutting knife.
  • Detecting the loaf of bread on the cutting knife has the advantage that no blank cuts have to be made and the cutting process is much faster can begin.
  • an electrical connection is formed between the feed plate and / or gripper and cutting knife.
  • the loaf of bread forms an electrical connection as soon as it touches the cutting knife.
  • a current flow from the feed plate and / or the gripper via the loaf to the cutting knife can then be measured.
  • the current of a motor that moves the gripper and / or the feed plate is measured. If the cutting knife creates mechanical resistance for the loaf, this motor current increases.
  • a transverse force triggered by the loaf of bread can be measured with strain gauges or other sensors at the bearing of the knife arm when the loaf of bread presses against the cutting knife.
  • a transverse force triggered by the loaf of bread can be measured with strain gauges or other sensors on the gripper and / or the feed plate when the bread presses against the knife.
  • Another preferred embodiment of the bread slicing machine is characterized in that the electronic control device is designed to cause the claws of the gripper to extend out of the feed plate and the claws to reach into the fixing section of the still uncut loaf of bread in the feed shaft when the Detection device detects the loaf of bread hitting the cutting knife.
  • the loaf of bread is not fixed until the cutting process begins.
  • the cutting knife takes on the function of a holding plate, so that the loaf of bread is fixed between the feed plate and the cutting knife when the claws are inserted.

Abstract

L'invention concerne une trancheuse à pain (1) comprenant une lame de coupe (5), une trémie d'alimentation (6), une trémie de réception (7) jouxtant la trémie d'alimentation (6) jusqu'à une fente de lame (5') ainsi qu'une plaque d'avancement (12) présentant un dispositif de préhension (13) muni de griffes, ladite trancheuse à pain se caractérisant en ce que l'axe de liaison (a) de la trémie d'alimentation avec la trémie de réception est agencé incliné d'au moins 30° par rapport à la verticale, et en ce qu'un dispositif de commande (14) électronique permet aux griffes de sortir et d'entrer dans une partie de fixation avant, s'étendant en direction de l'axe de liaison, d'une miche de pain introduite dans la trémie d'alimentation et permet également de transporter la miche de pain encore non tranchée jusque dans la trémie de réception via la fente de lame, le dispositif de commande effectuant de manière automatique pendant le transport un déplacement multiple de la lame de coupe dans la fente de lame de manière à détacher à chaque fois une tranche de la miche de pain, et ensuite, la lame de coupe est ressortie totalement de la fente de lame de manière à permettre la poursuite du transport de la tranche découpée dans la trémie de réception ainsi que du reste de la miche de pain via la fente de lame. L'invention permet ainsi d'obtenir de manière simple en termes de construction et avec une économie de matériel un processus de coupe stable et rapide.
