Definitions

  • the invention relates to a support device for clippings on a clippings wagon of a slicing machine with a slide which is arranged on a rail near the cutting plane, the dimensions for fixing the clippings in the cutting area are adjustable.
  • clippings holders which comprise a swivel arm with a holding plate and a rest holder.
  • the swivel arm is swiveled up, a clippings are placed on the clippings wagon and fixed in position when the swivel arm is swiveled back by the holding plate.
  • the clippings are then pushed against an adjustable stop plate to which the circular knife connects.
  • Automatic slicers are also known, in which the cut wagon is moved back and forth along the stop plate by an electromechanical reversing drive.
  • a clippings e.g.
  • a sausage stick is held in place by the above-described clamping using a swivel arm and holding plate, but the part of the clippings located directly in the cutting area moves, which absorbs the reaction forces of the circular knife and, if necessary, the frictional forces of the cut surface of the clippings on the stop plate.
  • a known support device which comprises a rail arranged on the clippings wagon near the cutting area above the support surface of the clippings wagon, which carries a slide that can be pressed laterally against the clippings.
  • this slider With the help of this slider, the clippings can be held in the cutting area in such a way that they cannot avoid the cutting forces and this results in geometrically exact cut slices even with relatively soft clippings. It has proven disadvantageous, however, that this support device must be adjusted manually and adapted to the respective clippings and that the clippings are distorted as a result of the simultaneously required advancement of the clippings.
  • the invention aims to provide an automatic support device for clippings in the clipping area, the slider of which automatically adapts to the respective clippings sizes and which holds the clippings in place during the clipping, but opens when the clippings are fed.
  • the slide is designed as a cantilever projecting from a slide guide, in particular a sleeve, and the slide guide is mounted on the rail in a self-locking manner under load, and in that the slide guide with an electric drive, in particular with a belt drive, via a self-locking device which cancels the self-locking Attack point is connected to the sliding guide.
  • the rail is arranged cantilevered horizontally above the contact surface of the clippings wagon and the slide in the direction of the contact surface of the clippings wagon, then the clippings are pressed against the shoulder of the clippings wagon and are thus within two rigid surfaces and two adjustable holding or clamping devices enclosed in a rectangle.
  • Another embodiment provides that the rail in the vertical direction and at right angles to the support surface of the clippings wagon and the slide in the parallel direction to the support surface are arranged cantilever. In this way, deviations in position of the material to be cut in the vertical direction are prevented.
  • Sliders can also be provided in both of the aforementioned directions and / or also in a 45 ° position to the contact surface of the material to be cut.
  • the rail is designed to be folded up or folded away to the side. This position is used to load the clippings wagon with clippings.
  • a specific embodiment of the invention is characterized in that an electric motor is provided for the belt drive, which can be switched off in a current-limited manner when the slider runs onto a clippings and / or can be switched over to a reduced holding voltage. If the slider hits the clippings, it increases Motor current of the drive, which is monitored and which is switched to a gentle holding voltage when an adjustable threshold value for switching off or switching over the motor is reached.
  • a control for driving the slide, which reverses the slide drive when a feed drive of the clippings is switched on and leads the slide drive into the supporting position when the feed drive is switched off.
  • the feed drive and the drive of the clamping device work alternately. A feed against the clamping forces can be avoided in this way.
  • the slide or the slides are connected to a position indicator, the drive in particular being connected to a pulse counter for counting pulses proportional to the feed, and if the signal from the position indicator is used to determine the size , in particular determining the diameter of the clippings a controller for a depositing system of cut slices of the clippings can be fed.
  • Laying systems often work taking into account the clippings dimensions so that mutual distances between clippings slices and overhangs on the edge can be adapted on a tray, for example a clippings diameter.
  • measuring devices are usually provided on an optical basis. If a support device according to the invention is used, then it can also take on the task of detecting the diameter or material size.
  • FIG. 1 schematically shows a section through a clippings wagon along the line I-I in FIG.
  • a clippings wagon 1 can be moved back and forth in the direction of the arrow (arrow 2) on a slicing machine relative to a stop plate 3 and a knife disk 4. In automatic machines, this stroke of the cutting process is provided by an electric reversing drive.
  • Guide rods 5, 6 are provided on the clippings wagon 1, on which a guide carriage 7 for a pivotable clippings holder 8 is mounted. 2 shows, sits on the guide rod 5 (with this rotatably connected) a carrier 9 with a rail 10 on which a sleeve 11 is slidably mounted.
  • the sleeve 11 carries a widely protruding slide 12 which, according to FIG. 1, presses a clippings 13 against the shoulder 14 of the clippings wagon 1 and in this way holds it in the cutting region near the immediate cutting plane.
  • An electric motor 15 is provided on the rail 10, which is connected to the sleeve 11 via a toothed belt drive 16.
  • the point of attack 17 on the sleeve 11 is chosen so that an inclination of the sleeve 11, due to the clippings 13 after the slider 12 has run thereon, is counteracted when the sleeve 11 is withdrawn.
  • the inclined position of the sleeve 11 on the rail 10 results in a self-locking which prevents the slide 12 from retracting. Only when the toothed belt drive 16 picks up at the point of application in the release direction does the self-locking release and the clippings 13 are in the cutting area, e.g. for the feed, released.
  • the slider 12 can be moved back to the position 12 '.
  • the carrier 9 sits positively and immovably on the guide rod 5, which is rotatably supported at its ends (Fig. 2).
  • An electric motor 18 causes the rotation of the carrier 9 and thus the rail 10 together with the sleeve 11 and the slide 12. This rotation is shown in Fig. 1 by the broken line position of the carrier 9 'and the rail 10'. In the swung-out state, the clippings wagon 1 can be loaded.
  • a controller 19 coordinates the switching on or switching over of the electric motor 15 for the belt drive 16, of the electric motor 18 for pivoting the entire support device in and out, and has an output 20 for the reversing drive of the clippings wagon 1 and a further output 21 for the feed drive the clippings 13.
  • the controller 19 When a clippings 13 is placed on the clippings wagon 1 and the cutting process is started, the controller 19 first activates the feed drive for the clippings 13 so that it reaches the cutting position. The motor 15 is then switched on via the controller 19. In the with full lines 1 drawn position of the slide 12 this runs onto the clippings 13 and blocks the motor 15, so that the motor current increases. The controller 19 detects that a preset limit value has been exceeded and switches the motor voltage (for example 24 V) to the gentle holding voltage (for example 12 V). Thus, the slider 12 presses laterally on the clippings 13 with constant force and holds them in the cutting area. As a result of the tolerances between the sleeve 11 and the rail 10, it tilts when the slider 12 runs onto the clippings 13 and assumes a self-locking inclined position, which is only released when the belt drive 16 moves back.
  • a preset limit value for example 24 V
  • the gentle holding voltage for example 12 V
  • the control 19 switches on the reversing drive for the cutting process. After each stroke, the clippings of the clippings 13 are released in the clippings plane, so that the clippings 13 can be fed according to the cutting thickness. After each advance, the belt drive 16 guides the slider 12 against the clippings 13 into the self-locking position. At the end of the cutting process, the control 19 leads via the motor 15 and the toothed belt drive 16, the sleeve 11 and thus the slider 12 back into position 12 'or even further away from the clippings 13 and activates the swivel drive (motor 18).
  • the rail 10 can also be designed so that it can be pivoted down by the motor 18 to rest on the clippings 13.
  • the motor 18 switches to a holding voltage in a current-limited manner.
  • the slide 12 runs on the support surface of the clippings wagon 1 and backs away against the spring force in a guide of the sleeve 11.
  • the slide 12 is fed into the holding position.
  • the pivot position of the rail 10 and / or as in the embodiment according to FIG. 1, the position of the slide 12 is a measure of the size of the material to be cut (for example the diameter a sausage in the cutting area).
  • Position indicators 22 count the pulses of the drive motor 15 until the clippings 13 are clamped and supply this value as a measure of the clippings size to a controller for the depositing system.
