Definitions

  • the invention relates to a drive arrangement for a cover gumming machine having a machine head driven by a drive motor and rotatable about a vertical axis with a plurality of quill shafts with plates for receiving ceilings, the quill shafts being rotatably mounted about axes arranged parallel to the vertical axis and each having a pinion , which is in engagement with a ring gear that can be rotated about the vertical axis and relative to the machine head.
  • a drive for a lid gumming machine is known from US-A-4,262,629.
  • the lids rotating with the quill shafts are loaded with a lid in one station.
  • the quills are raised and the plate presses the cover against a spring-loaded counterholder.
  • a liquid sealant or rubber compound is poured into the edge of the cover from a spray gun that is assigned to each sleeve and rotates with the machine head and is distributed evenly as a result of the rapid rotation of the cover.
  • the ring gear with which the pinions of the quill shafts are engaged is now driven by the same main motor as the machine head via a series of drive transmissions.
  • Another disadvantage of the known drive arrangement is that to change the speed of the sleeves relative to the machine head, e.g. when changing the format (changing the cover diameter), at least one gear pair must be exchanged to change the gear ratio.
  • the invention has for its object to provide a drive for a cover gumming machine, in which the quill shafts responsible for rotating the cover continue to rotate when the machine head is at a standstill, so that the liquid gum mass can still run.
  • ring gear with which the pinions of the quill shafts are engaged, is connected to a drive motor (auxiliary motor) separate from the drive motor (main drive).
  • the sprocket driving the quill shafts can continue to rotate, so that the covers held on the quills also do not come to a standstill and the rubber compound can run.
  • the speed of the sleeves depends not only on the speed of the ring gear but also on the speed of the machine head, with a direction of rotation of the machine head usually opposite to the rotation of the ring gear increases the speed of the sleeves.
  • a Further development of the invention provides to drive the ring gear by the separate drive motor (auxiliary motor) in such a way that the speed of the ring gear decreases with increasing speed of the machine head.
  • Such a speed reduction of the ring gear is advantageously brought about in that the connection between the ring gear and the separate drive motor (auxiliary motor) takes place via a differential gear, the rotating housing of which is driven by the separate drive motor, the one output shaft of the differential gear being geared to the ring gear and the other output shaft is connected to the first drive motor (main drive).
  • the ring gear can also be driven by the separate drive motor (auxiliary motor) via a fixed transmission ratio if the speed of the separate drive motor is changed via a control device depending on the speed of the machine head.
  • the speed of the machine head and thus the output of the machine can be freely selected or predefined and can thus be adapted to the most varied of circumstances. This is of interest, for example, when there is an accumulation section in front of or behind the gumming machine or when the output of an upstream punch press changes. Also a formal change (change of Cover diameter) is unproblematic, since the correct rotational speed of the quill shafts for the respective cover diameter and the respective sealing or rubber compound is brought about in a simple manner by changing the rotational speed of the separate drive motor (auxiliary motor).
  • the gumming machine 1 has a central column 3 with a vertical axis 4 which is firmly connected to the machine frame 2.
  • a turret or machine head 5 is rotatably mounted with a plurality of through holes 6 arranged parallel to the axis 4.
  • Quill sleeves or bearing sleeves 7 are axially slidably guided in the through bores 6, in which quill sleeves 8 are in turn rotatably mounted.
  • the sleeve shafts 8 carry a plate 9 suitable for receiving a can lid at the top and a gear or pinion 10 below. Both the plate 9 and the pinion 10 are firmly connected to the shaft 8.
  • each bearing sleeve 7 On the side facing away from the axis 4, each bearing sleeve 7 has a guide element 11 which is guided in a guide groove 12 in the machine head 5 and prevents rotation of the sleeve with respect to the machine head.
  • a roller 13 On the side facing the axis 4, a roller 13 is arranged on each sleeve 7, which runs a control cam 14.
  • the control cam 14 is embedded on the circumference of a rotary part 15 which e.g. is non-rotatably connected to the column 3 with a wedge connection, not shown.
  • the control curve 14 causes an axial movement of the sleeve sleeve 7 and thus the sleeve shafts 8 and the plate 9 and the pinion 10.
  • a counterholder 16 and a spray gun 17 are arranged on the rotatable machine head 5 above each plate 9.
  • the counter holder 16 is rotatably mounted at the lower end of an axially movable pin 18.
  • the bolt 18 is pressed down by a spring 19.
  • the lowermost position of the counter-holder 16 is determined by a rear stop 20.
  • the machine head 5 has a ring gear 21 which is in engagement with a gear wheel 22 (not shown) driven by the main motor.
  • a sleeve 23 (drive sleeve) is rotatably mounted on the column 3 within the machine head 5, the machine head 5 in turn being supported on the sleeve 23 with its lower end.
  • the sleeve 23 has a ring gear 24 and 25 at the top and bottom.
  • the pinions 10 of the quill shafts 8 are in engagement with the upper ring gear 24. So that the pinions 10 remain securely engaged with the ring gear 24 even with the axial stroke caused by the control cam 14, they have a correspondingly large height or width.
  • a motor 27 (hereinafter also referred to as auxiliary motor) and a differential gear 28, which is independent of the main drive of the cover gumming machine, is mounted.
  • the differential gear 28 has around its housing, which is rotatable about a vertical axis 29, a toothed ring 30 which is fixedly connected to the housing and which engages with the drive pinion 31 of the auxiliary motor 27.
  • the differential gear 28 Coaxial with the axle 29, the differential gear 28 has two output pinions 32 (top) and 33 (bottom).
  • the output pinions 32 and 33 are non-rotatably connected within the housing in a known manner with bevel gears which are in engagement with each other again by differential gears mounted in the housing.
  • the upper output pinion 32 is - like the gear 22 driven by the main drive - in engagement with the ring gear 21 of the machine head 5.
  • the lower output pinion 33 is in engagement with the lower ring gear 25 of the sleeve 23 via an intermediate gear 38 (see FIG. 2) .
  • the speed n K of the turret 5 corresponding to the output of the cover gumming machine is determined exclusively and directly by the speed of the main drive (gear wheel 22).
  • the speed n P / K related to the machine head 5 of the quill shafts 8 and the plate 9 firmly connected to them about its own axis is determined independently of the speed n K of the machine head 5 exclusively by the speed n27 of the auxiliary motor 27.
  • the speed n27 of the auxiliary motor 27 or its drive pinion 31 is assumed to be 1400 min ⁇ 1.
  • the invention is not limited to the use of a differential gear.
  • the machine head 5, as indicated in FIG. 4 can be mechanically coupled to a tachometer generator 40 as a speed sensor.
  • the auxiliary motor 27 is connected to the tachometer generator 40 via a preferably electronic actuating device 41.
  • the actuating device 41 only needs to emit a signal that the speed n27 in the auxiliary motor 27 causes.
  • i 27/24 is a fixed transmission ratio from the auxiliary motor 27 to the ring gear 24.
  • the signal of the actuating device 41 contains only one variable - the speed n K of the machine head 5 - and is otherwise composed of constant values that can be input.
