- This machine comprises a first loading and unloading compartment, which is connected to a second receiving compartment. Between the first and the second compartment a cutting member, in particular a circular blade, is provided for cutting slices of the bread.
- the first compartment has a support surface for the bread extending vertically or inclined at an angle less than 45 ° with respect to a vertical direction. The bread can be moved from the first compartment to the second compartment in a direction of movement of the bread parallel to the support surface.
- This machine has a movable pusher which is arranged in the first compartment and which can be moved in the direction of movement of the bread to exert a pushing force on the bread to direct it to the second compartment.
- a mobile support is provided in the second compartment.
- This support is also movable in the direction of movement of the bread to support the sliced portion of the bread and to transport the bread, after its complete slicing, to the first compartment.
- the invention relates, in particular, to a machine whose base occupies a relatively small area compared to conventional automatic slicers and wherein a bread is introduced into the same compartment from which it is recovered after cutting.
- DE 9310092 discloses a bread slicer in which the bread is transported in a vertical direction and cut into slices during its downward movement. When using this machine, the part uncut bread rests on the cutting blade while cutting a slice of bread. This can cause several problems, such as, for example, moving the uncut portion of the bread relative to cut slices or the deformation of the bread crumb. In addition, in the machine of DE 9310092 the cut bread has to be recovered from a compartment different from that in which the bread to be cut has been introduced.
- DE 4431808 provides a solution to these problems by providing a bread slicer in which the bread is sliced during its upward movement.
- the sliced portion of the bread rests on the cutting blade, which gives rise to the same problems.
- the invention aims to remedy these problems by providing a machine to automatically cut a bread in which it is avoided that the bread rests on the cutting blade to prevent it from moving under the action of the blade cut or that the bread crumbs is deformed.
- the invention ensures, in particular, that the pressure force exerted by the bread on the cutting blade in the direction of advancement of the bread is nonexistent or very limited.
- the aforementioned mobile pusher comprises hooking means for gripping and holding the bread against the action of gravity to maintain the uncut portion of the bread in successive fixed positions in the first compartment.
- Means are provided to drive the pusher in the direction of movement of the bread and advance to the second compartment in steps corresponding to the thickness of a slice to be cut.
- the attachment means comprise at least one hook that can penetrate the bread to grasp and hold it.
- the attachment means for the bread allow, in particular, to hold the end of the opposite bread at the end located near the movable support.
- the aforementioned hooking means are retractable relative to the pusher and are movable between a retracted position and a stretched position, for grasping and holding the bread in the stretched position.
- the machine has a proximity detection system of the bread relative to the pusher for driving the hooking means of the retracted position to their stretched position to grip the bread when it comes in contact with the pusher or is positioned at a small distance from it.
- the bread proximity detection system comprises a detector which is attached to the pusher. This detector is intended to detect the proximity of the bread or the contact of the bread with the pusher.
- the detection system comprises a plate pivotally mounted to the pusher on the side of the movable support, this plate cooperating with a switch which controls the attachment means.
- the detection system comprises a capacitive proximity sensor cooperating with the attachment means to drive them when the presence of a bread near the pusher has been detected.
- the cutting member comprises a blade movable along a cutting plane extending substantially transversely to said direction of movement of the bread, between the first compartment and the second compartment.
- At least one clamping device is present in the first compartment for exerting a pressure force on the bread in a direction substantially transverse to the direction of movement of the bread in order to keep it in a fixed position in the first compartment.
- the aforesaid pusher is driven in the direction of movement of the bread by driving means to overcome the friction force between the bread and the clamping device, to advance the bread to the second compartment.
- This latter embodiment may optionally be applied without the aforementioned attachment means being provided in the machine.
- the clamping device comprises a first clamping element extending over at least a portion of the height of the first compartment in said direction of displacement and extending, preferably, at least over half of this height.
- the clamping member cooperates with drive means for moving the clamping member between a remote position, in which the roll bears freely against the support surface, and a clamping position in which the roll is clamped. between this clamping element and a counterplate present in the first compartment.
- the counter-plate extends substantially transversely with respect to the said support surface and in the direction of movement of the bread.
- the counterplate may also be formed by the surface of the bread support.
- the aforesaid counter-plate is formed by a second clamping element cooperating with drive means for moving the second clamping element between a remote position, in which the roll is presses freely against said support surface, and a clamping position, wherein the bread is clamped between the first and second clamping members.
- said drive means make it possible to keep the clamping element in contact with the bread as it moves towards the second compartment.
- the invention also relates to a method for automatically slicing a bread or the like, wherein a bread is placed against a support surface in a first loading and unloading compartment, and then moved downwardly following a direction of movement to a second receiving compartment.
- the direction of movement is substantially vertical or inclined at an angle less than 45 ° with respect to a vertical direction.
- the inclination of this direction of displacement relative to the vertical is between 0 ° and 20 °.
- This method is characterized in that after the bread has been placed against said support surface, the upper end of the bread is grasped by hooking means and this end of the bread is held against the gravity as it moves downhill while slices are cut.
- the hooking means are moved at a speed substantially equal to the speed of the movable support and the bread is moved to the second compartment in discrete steps by maintaining the upper end of the bread by the attachment means, so as to make advance the bread until it is completely sliced.
- the cut bread is then transported in said direction of movement to the first compartment so as to be able to recover it in the cut state.
- a pressure force is exerted on the bread in the first compartment in a direction substantially transverse to said direction of movement, so that the bread is held in a position fixed by a friction force.
- the bread is then moved to the second compartment maintaining said pressing force and exerting a pushing force on the bread in its direction of travel. This pushing force is greater than said friction force to advance the bread until it is completely cut into slices.
- the cut bread is then transported in said direction of movement to the first compartment in order to recover the cut bread.

- the machine according to this embodiment differs from that shown in FIGS. 8 to 12 in that the clamping device 106 comprises two clamping elements 107 and 107 '.
- Each of these clamping members 107 and 107 ' comprises a resilient plate 108, respectively 108', which is attached to its upper portion 114 relative to the support surface 103 and which extends substantially transversely to that surface 103.
- the clamping members 107 and 107 ' are preferably somewhat bent and mounted in the first compartment 101 so that the loading space 115, extending between the clamping members 108 and 108', presents the the appearance of a funnel for the bread 104 to be cut.
- the narrow portion of this funnel, formed by the clamping members 107 and 107 ' extends a short distance above the cutting plane, along which the blade 112 moves to cut the bread.
- a movable support 105 is provided in the second compartment 102 and extends, for example, below the cutting plane at a distance from this plane corresponding to the thickness of a wafer. As described in connection with the previous embodiments of the invention, this movable support 5 serves to support the sliced portion of the bread.
- the pusher 110 provided above the loading space 115 is lowered and exerts a pushing force on the bread 104 in its direction of movement to the second compartment 102.
- This pushing force is such overcoming the holding force to move the bread 104 to the second compartment 102 in successive discrete steps corresponding to the desired thickness of a wafer.
- the clamping elements 107 and 107 ' are deformed in an elastic manner so as to allow the passage of the bread 4 between these clamping elements 107 and 107' while maintaining a pressing force against the bread to prevent the bread from moving under the force of gravity.
- the cutting blade 112 After each movement a distance corresponding to the desired thickness of a slice, the cutting blade 112 is moved along the cutting plane through the space 113 provided, for this purpose, to cut a slice of the bread.
- the downward movement of the mobile support 105 is synchronized with the movement of the pusher 110 to support the cut portion of the bread as the bread advances, as shown in FIG. 16.
- the pusher is positioned above the cutting plane at a distance therefrom corresponding to the thickness of the last cut slice.
- the clamping elements 107 and 107 ' are withdrawn to a position remote from each other by the action of the drive means provided for this purpose, so that that the distance, in a plane parallel to the cutting plane, between the clamping elements 108 and 108 'is greater than the width of the bread cut in this plane.
- the cut bread is then reassembled to the first compartment 101 by moving the mobile support 105 with the bread towards this first compartment 101. After the arrival of the cut bread in the first compartment 101, the pusher 110 is moved away from the end corresponding bread to allow the bread to be removed from the first compartment 101.
- clamping members 107 and 107 ', formed by elastic plates 108, of the embodiment of the invention shown in FIGS. 13 to 16, can also be moved by drive means, as is the case in the embodiment shown in Figures 8 to 12.
- the clamping members are not necessarily limited to resilient or non-elastic plates, but may also include one or several flexible straps extending essentially in the direction of movement of the bread. When the clamping member is moved to said clamping position, this clamping member is deformed somewhat to accommodate the shape of the corresponding lateral side of the roll.
- Such a flexible belt may be formed by a belt conveyor, the bread-directed portion of which extends substantially in the direction of movement of the bread.
- the thrust force can be exerted partially or entirely by this flexible belt when the latter is driven in its longitudinal direction.
- the clamping element is formed by a conveyor belt
- the conveyor by the pushing force exerted by the pusher 110 on the bread, the conveyor is driven by the bread due to the friction force present between the conveyor and the bread.
- the various embodiments of the machine according to the invention may comprise the pusher with the hooking means and the clamping device cooperating in a single machine. It is also possible that the machine comprises only the clamping device or only the pusher with the attachment means, to maintain the bread against gravity. This is also the case for the process according to the invention.
- the invention relates to a machine for automatically cutting a bread, in particular a bread slicer, having a support surface for the bread, which is preferably slightly inclined relative to the vertical.
- This support surface extending along the two compartments 1 and 5 is, in particular, inclined at an angle less than 45 ° with respect to a vertical direction and preferably less than 20 ° with respect to the vertical direction. Nevertheless, it is also possible that this support surface extends substantially vertically.
