Definitions

  • ABSTRACT A sorting device for cylindrical vessels having a length greater than the diameter, such as bottle caps or the Nacknhelm/Rhem, Germany like, including a container for actuating disordered vessels in 1 Pnomy J ly 29, 1969 which the vessels are picked up in the container by a conveyor Germany paddle wheel rotating about an inclined axis and having inter- P 19 38 474-8 nal axial parallel conveyor pockets in which the vessels are aligned axially parallel with an opening through which they SORTING DEvlCE FOR CYLINDRCAL VESSELS fall into individual channels of an aligned magazine drum rotating coaxrally and synchronously with the conveyor pad- 14 Claims, 3 Drawing Figs.
  • the invention relates to a sorting device for cylindrical vessels, whose length is greater than their diameter, such as bottle caps or the like, said device having a container for accommodating the disordered vessels.
  • a known sorting device suited for this purpose has a container for accommodating the disordered vessels, which is in the form of a vibrator pot.”
  • the upright cylindrical container possesses on its inner wall a helical runup channel.
  • the container is resiliently supported and is so agitated by an oscillating drive that the torsional vibrations occurring about the container axis cause the vessels on the runup channels to advance upwards.
  • In the runup channels there are provided recesses so that any vessels which are not aligned in the correct manner, fall back again into the container. In this way only vessels aligned in one direction arrive at the delivery point of the sorting device.
  • These vibrator pots have the disadvantages that their capacity, i.e., the number of items which can be sorted per unit of time, is restricted, that the amount of space taken up is very large and that operation is very noisy.
  • the object of the invention to produce a sorting device which does not have the disadvantages of the known device.
  • This is achieved according to the invention in that the vessels are picked up in the container by a conveyor paddle wheel rotating about an inclined axis and having internal, axially parallel conveyor pockets, and are then aligned axially parallel and on opening of an aperture they fall into individual channels, in alignment with the conveyor pockets, of a magazine drum rotating coaxially and synchronously with the conveyor paddle wheel, in which channels there are arranged central retaining rods primarily projecting approximately as far as the longitudinal center of the channels, which rods support the vessels at the vessel bottom and on further rotation of the magazine they are retracted by means of a stationary cam, those vessels whose apertures are facing away from the retaining rods and those whose apertures are facing the retaining rods leaving the magazine drum by separate conveying routes.
  • the conveyor paddle wheel By means of the conveyor paddle wheel many cylindrical vessels can be removed from the container in quick succession and fed to the channels of the magazine drum, there thus being achieved with this sorting device a high capacity (number of items per unit of time).
  • the retractable retaining rods arranged in the channels of the magazine drum carry out a sorting of the vessels into two groups, i.e., those vessels whose aperture is turned away from the retaining rods, and those whose aperture is facing the retaining rods.
  • each group the vessels are arranged with their apertures aligned, so that they can leave the magazine drum by separate conveying routes, within each individual conveying route they are uniformly aligned however.
  • the sorting into two groups of differently aligned vessels is therefore possible, because those vessels whose aperture is facing the retaining rod, pass with their aperture over the retaining rods until the tip of the retaining rod touches the bottom of the vessel; on the other hand those vessels whose aperture is remote from the retaining rods, can only fall into the channels of the magazine drum until the vessel bottom meets the tip of the retaining rod.
  • the two groups of vessels are therefore situated according to their position of alignment in axially juxtaposed zones of the magazine drum, so that removal by separate conveying routes is easily possible.
  • each conveyor pocket at the lower axial end of each conveyor pocket an aperture, which is opened on rotation of the paddle wheel by a stationary sickle-shaped bar, in order to let the vessels drop out. Consequently a vessel picked up by the conveyor paddle wheel in its lower region is elevated up to a given height, which is determined by the end of the sickleshaped bar, before the vessel can drop into the corresponding channel of the magazine drum.
  • the paddle wheel is connected firmly to the magazine drum and can rotate with this. This arrangement permits a particularly simple and inexpensive construction of the magazine drum and paddle wheel.
  • the retaining rods are guided so as to slide axially in a ring connected with the magazine drum and they engage with a guide component projecting towards the axis of rotation in a control groove of a stationary cylinder cam. Consequently it is possible to achieve an axial displacement of the retaining rods in the conveyor channels, dependent on the angle of rotation of the magazine drum.
  • the bottoms of the vessels with their apertures remote from the retaining rods are supported and guided by a stationary sickleshaped bar.
  • the two groups of differently aligned vessels arranged axially side-by-side on the periphery of the magazine drum are moved by the stationary sickleshaped bar, but separated from one another, up to the position where they are removed from the magazine drum for further convenience.
  • the vessels pass from the channels of the magazine drum into compartments or chutes which prevent canting of the cylindrical vessels and which serve as stowage space. It is thus possible to forward the vessels in the aligned position even to a farther removed subsequent treatment station.
  • compartments can at the same time serve as stowage space in order to compensate to a certain extent for varying fluctuations in throughput of the sorting device and of the subsequent treatment machine.
  • the two chutes are so twisted in relation to one another at their outlet that the vessel bottoms are aligned at the end of the chutes in a uniform direction. The fact must therefore be taken into consideration that the vessels are variably aligned in the two separate conveying routes.
  • the inclined position of the axis of rotation of the sorting device is adjustable, in order to alter the sliding speed of the vessels in the channels. In this way by varying the inclination of the whole sorting device it is possible to influence favorably the operating sequence.
  • FIG. 1 shows a simplified view in perspective of a sorting device according to the invention, in which individual parts of the outer wall and of the paddle wheel are broken away,
  • FIG. 2 shows a simplified side view of a delivery compartment or chute as used in the device according to FIG. 1, and
  • FIG. 3 shows partly in section a further form of embodiment of a sorting device according to the invention.
  • the sorting device represented in FIG. 1 comprises an obliquely arranged container 1 with adjustable inclination and open at the top, into which the vessels 2 are fed in disorder.
  • a disc 3 forming the bottom surface of the container and a conveyor paddle wheel 4 connected to it.
  • apertures 6 are provided which are associated in each case with a pocket of the conveyor paddle wheel, the diameter of which apertures is so great that a cylindrical vessel 2, which is situated in a conveyor pocket 5, can pass through the aperture 6.
  • a magazine drum 7 rotating in synchronism with the disc 3 and with the conveyor paddle wheel 4 is arranged coaxially to the conveyor paddle wheel below this disc 3, which drum has channels 8.
  • the channels 8 are situated in each case in extension of a conveyor pocket 5 and serve to accommodate the cylindrical vessels 2 falling through the apertures 6, which in the example of embodiment represented are bottle caps.
  • Central retaining rods 9 project from the side remote from the conveyor paddle wheel 4 into the channels 8, which rods primarily reach up to the longitudinal center of the channels 8.
  • the retaining rods 9 are arranged to slide axially in a ring 10, which is connected to the magazine drum 7 and rotates with the latter.
  • the rotation is effected by means of a drive motor (not shown) via a drive shaft 11 in the direction of rotation represented by the arrow 12.
  • the lower ends of the retaining rods 9 are bent round towards the axis of rotation of the sorting device and form in each case a guide portion which engages in a control groove 13 of a stationary cylinder cam 14.
  • Another stationary sickle-shaped bar 16 is arranged axially on the periphery of the magazine drum 7 approximately in its longitudinal center. From a point (not shown) situated behind the sorting device in FIG. 1 two separate chutes or compartments l7 and 18 lead away from the periphery of the magazine drum 7. Such a chute is represented simplified in a side view in FIG. 2.
  • the inner walls of the chute 17 extend in such a way that the cylindrical vessel 2, which is a bottle cap in the example, follows a zigzag path through the chute, its aligned position being retained however, i.e., the axis of the cap is only moved parallel, but not tilted.
  • a light source 19 On one side of the chute 17 there is arranged a light source 19, from which light reaches through apertures 20 in the walls of the chute 17 a light-sensitive apparatus 21, for example a photoelectric cell.
  • the photoelectric cell 21 is connected to a switch circuit (not shown), which cuts off the drive motor of the sorting device if the vessels rise in the chute 17 to the level of the light barrier 19, 21.
  • the mode of operation of the sorting device according to FIGS. 1 and 2 can be described as follows.
  • the cylindrical vessels to be sorted are placed in the container 1 in disorder.
  • the vessels 2 project into the aperture 6 and slide along the stationary sickleshaped bar up to its end.
  • the vessel After the aperture 6'has been uncovered by the bar 16 the vessel, present in the conveyor pocket 5 and aligned axially parallel to the axis of rotation of the sorting device, falls through the aperture 6 into a channel 8 of the magazine drum 7. If the particular vessel 2 is with its aperture facing the retaining rod 9, then it drops with its aperture over the retaining rod 9 until the tip of the retaining rod 9 meets the bottom of the vessel 2. If a vessel 2 falls into the channel 8 with its aperture remote from the retaining rod 9 however, then it comes into contact with the tip of the retaining rod 9 with the outer surface of its bottom and therefore it comes to lie entirely above the retaining rod.
  • the vessels 2 are now situated on each side of the sickleshaped bar 16 arranged so that their bottoms in each case point towards the bar 16.
  • the vessels 2 then pass into two separate chutes 17 and 18 through an aperture in the wall surrounding the channels 8 of the magazine drum 7, in which chutes they retain their particular aligned position and arrive at a further processing machine under the influence of gravity.
  • the machine arranged at the outlet side is therefore for example a capping machine.
  • the stationary parts of the sorting device such as the container l, the sickle-shaped bars 15, 16 and the cylinder cam 14 are fastened to a carrier 22 which is pivotably and lockably connected, by means of a screw connection 23, to the base support 24 of the device.
  • FIG. 3 there is represented another embodiment of the sorting device according to the invention.
  • the drive of the rotating parts of the device is effected by a drive motor 30 which is fixed to the base support 24 of the device.
  • Via an infinitely variable V-belt drive 31 there is driven an intermediate shaft 33 supported in a movable bearing block 32.
  • the drive of the conveyor paddle wheel 4 is effected via a universal-joint shaft 34.
  • the disc 3, which forms the bottom of the container 1, and also the ring 10 rotate together with the conveyor paddle wheel 4.
  • the retaining rods 9 are bent to form a U-shape in the example of embodiment represented in FIG. 3, the shank of the U lying near the axis of rotation of the device being the longer one and being guided in the ring 10 and also the disc 3.
  • the shorter shank of the retaining rod 9 serves to accommodate and hold the vessels 2 in the channels 8 of the magazine drum 7.
  • the stationary sickle-shaped bar 16 is formed, as is also the bar 15 (not shown), by an inwardly projecting part ofthe outer casing of the device, which is connected to the container Guide heads 35 are attached to the longer shanks of the retaining heads 9, which heads engage in a slot 36 on the cylinder cam 14 serving as a guide groove.
  • the tilting of the sorting device is effected by means of a stop screw 37.
  • the speed of rotation of the sorting device can be varied by means of the transmission system 31 for instance within a range of 5 to 25 r.p.m.; a speed of rotation of 12 to 15 r.p.m. has proved advantageous.
  • the use of the sorting device for bottle caps indicated in the example of embodiment is only to be taken as an explanatory example.
  • the device can be generally used with advantage anywhere where cylindrical vessels, whose height is greater than their diameter, have to be sorted; the device according to the invention is especially useful with light vessels susceptible to damage and deformation. It is precisely with such types of usage that it has proved particularly advantageous that the device according to the invention sorts the vessels very carefully.
