  • An electric control motor is provided, and a portioning drive is driven by the electric control motor and cow Fie'ld 17735 37 pled with said rotation servo-valve, whereby the feeding duration of said feeding pump and the portioning size, respectively, is determined by a settable driv
  • the present invention relates to a hydraulically operating sausage-filling-and turn-off-machine, in which the feeding pump for the filling material is driven for portioning intermittently by a hydraulic motor with adjustable feeding duration.
  • This type of control has the advantage, that, due to the extremely low inertia of the control elements, a very fast reaction of the drive results in response to the control orders, which has as a consequence an appreciable increase of the working speed and of the exactness of the portion weights, compared with previous designs.
  • the present invention moves still one step further and makes the proposal, to control also the hydraulic motor for the drive of the turn-off device by a servo-valve.
  • the control of all working functions takes place by servo valves, contrary to known devices.
  • the return guide takes place mechanically and the nominal valve is fed to the servo valve with an electric control motor in connection with a mechanical drive.
  • control edges in the servo valves can be designed easily such, that the hydraulic motor can be selectively accelerated and braked soft and shock-free. Also the control motors can be controlled electrically such, that nearly each desired movement characteristic is obtainable. By the far-reaching elimination of power transmitting drives and hydraulic control elements, the gen eral structure of the machine is decisively simplified.
  • the servo valve and the electricv control motor control the machine not only during the portioning process. Also during the normal filling without portioning these elements control the working speed of the feeding pump. By switching-on and switching-off of the control motor also the feeding pump is switched-on and I -off.
  • a predetermined path is limited in the portioning drive settable and mechanically, by example, by abutment, for securing the portion size, whereby the transmission between the drive and the servo valve remains constant.

  • the pump 2 is driven by means of the shaft 3 by a hydraulic motor 7 (not shown in detail) by meansof a reduction gear 8.
  • the intermittent driving movements of the motor 7, and, thereby of the pump 2 are controlled by a servo-valve 9.
  • the control position of the rotating control slide 10 of this valve which is formed as a piston slide, is determined by means of the gears 11 and 12 by the control motor 13 in connection with the portioning drive 14.

  • the returning oil is fed through the conduits 29 and 30, respectively, and a return filter 31 to the oil container.
  • the servo-valve 9 separately shown in FIG. 2 with the portioning drive 14 equals in structure and operation the servo-valve 17 with the drive 22 (FIG. 1), so that the following description can be applied for the intermittent drive of the pump 2 as well as for the likewise intermittent drive of the turn-off device 5. 7
  • the housing 32 of the servo-valve is, in addition to the piston slide 10 and 18, respectively, for the control of the hydraulic motor 7 and 16, respectively, also displaceably provided the pressure reduction valve 33 against the pressure spring 34.
  • This spring is arranged such, that the slide 33 throttles the feeding of a pressure medium from the conduit 27 through the channel 35'to the hydraulic motor, if the pressure of the pressure medium arriving from the motor through the'channels 36 and 37 into the chamber 38 reaches a predetermined value.
  • a control slide 10 of the servo-valve has the task, to control the quantity of the operating oil flowing from the pressure chamber of the hydraulic motor through the channel 36 to the control chamber 39 such that its escape is freed and closed, respectively, through the channel 40 to the conduit 30 during a predetermined time period. Since the hydraulic motor runs only during the passage of a predetermined specific quantity of pressurized oil, by the described control means the intermittent drive of the feeding pump 2 is brought about.
  • a portionwith a threaded bushing 45 which threaded bushing 45 is rotatably mounted in a mounting frame 46 and is screwable with a threaded pin 47 of the control slide 10.
  • the bearings 43 and 44 are arranged such, that they can drive the threaded bushing 45 always only in one direction of rotation, so that the control slide 10 is rotated independently from the direction of rotation of the control motor 13 always in the same direction of rotation and is axially displaced in the same direction, respectively.
  • the gear 12 of the control motor 13 is operatively connected with the portioning drive by means of a gear 50, on the shaft 51 of which sits a small gear 52, which is in engagement with a large gear 53.
  • a gear 50 On the shaft 54 of the gear 53 sits, in addition, freely rotatable a gear 55, which is in mesh with a worm 56, which is driven by a setting motor 57 (FIG. 3).
  • the worm shaft 58 is equipped with a gear 59, which drives a flexible shaft 61 by means of a gear 60, which shaft 61 leads to a counter, which is gauged such, that the produced portion weight is readable as a function of the position of the abutment cam 66 in the worm gear 55.
  • an abutment 64 which cooperates with a counter cam 65 on the periphery of the gear 53.
  • a further cam 66 is provided on the gear 55, which cooperates with the cam 67 by the gear 53.
  • the portion size and the portion weight, respectively is set forth such, that by corresponding selective switches, the cam 66 is brought into such'position, by means of the setting motor 57 and the intermediate glass 55 and 56, that the cams 65 and 67 can run through on the gear 53 in both directions of rotation between the abutment cams 64 and 66, which corresponds with a readable predetermined number of revolutions of the control motor 13.
  • the control motor 19 is switched-on and -off, respectively (FIG. 1), by means of a contact in the abutment cams 65 or 66 on the portioning drive 14 for the control of the tum-off movement.
  • the engagement of a cam on an abutment cam in the drive 22, which serves the setting of the turn-off number releases a new portion, in which the control motor 13 is switched into another direction of rotation.
  • the portioning and turn-off device is set at a selection switch on the tum-off speed zero.
  • the driving connection of the portioning drive 14 to the control motor 13, by example, electro-magnetic, is decoupled.
  • the filling process can now be controlled by means of a knee lever, whereby the feeding pump 2 runs, as long as the knee lever is down.
  • the filling speed corresponds with the number of revolutions of a control motor 13, which likewise can be set by means of a cylinder switch.
  • the machine set ting is the same as in case of continuous filling. Moreover the tum-ofi device 5 is removed. The timely pause between two portions results from the setting of the setoff speed on the control motor 19 and the set-off number.

  • the connecting gear 50 is equipped thereby with a threaded pin 70, on which the abutment nut 71 can be screwed.
  • An abutment body 73 can be screwed on the threaded bolt 72.
  • the latter is axially guided on a guided bolt 74, which is secured in the mounting frame and on which also the abutment nut 71 is axially guided.
  • the threaded bolt 72 is connected with the cardan shaft 75, which is equipped with a hand wheel 76.
  • the cardan shaft 75 drives a counter 63 by means of the gears 77 and 78, the scale of the counter 63 indicating the set portion weight as a function of the position of the abutment body 73.
