Definitions

  • the invention relates to an output unit for mounting under stacked goods chutes of vending machines, the output units are each block-shaped, with goods lying on their top and provided with an ejecting element that can be moved back and forth over its top, the bottom product in its forward movement / Pushes the pack of goods behind the stack of goods.
  • Such an output unit is known for example from DE-OS 38 02 399.
  • a locking spring is provided in front of the delivery opening of the goods shaft, which stabilizes the goods package during ejection and prevents the goods from tipping over prematurely into the output shaft.
  • a vending machine with several output units and product chutes in which a pivotable flap or locking rail is provided in front of the output openings of the product chutes, which is pivoted away during the goods issue. If such a flap is used to secure the goods shafts against unauthorized removal (manipulation of goods during the machine's downtime by means of wires or the like), special locking or actuating means (electromagnets or the like) are required to close the flap hold and only release or lift during goods issue.
  • a flap assigned to several product chutes is disadvantageous insofar as that when a product package is dispensed from a specific product chute when the flap is lifted, the dispensing openings of the other product chutes are also free, that is to say accessible, and goods packages can then be manipulated out of them.
  • the invention is based on the object of designing an output unit of the type mentioned in such a way that, on the one hand stabilization of the goods packs during the pushing out and thus trouble-free dispensing is achieved, and on the other hand a secure blocking of the goods dispensing opening of the goods hopper is achieved when the dispensing unit is at rest, which is only released when the goods dispenser is intended, and only at the goods hopper intended for dispensing .
  • the ejection element is in each case provided with a support part for the goods packs which can be displaced together with this, that the support part is articulated to the ejection element, that at the front end of the support part a locking lug is formed, which engages in front of the bottom goods pack when the support part is withdrawn (basic position), and that the support part is guided with support on the top of the dispensing unit such that it is pushed horizontally during the forward movement of the ejection element and folds down towards the end of the ejection stroke.
  • the advantages achieved by the invention consist in particular in that the packs are pushed straight out from under the stack of goods and are kept supported horizontally until the support, ie the support part folds down towards the end of the displacement of the ejection element, and the goods pack fall into the delivery shaft can.
  • the bottom pack of the stack of goods lies in full length on the support part and a locking lug at the front end of the support part protrudes in front of this pack so that the goods delivery opening of the goods shaft is securely blocked and no goods can be manipulated.
  • Another advantage can be seen in the fact that the front of the dispensing unit, when the support part protrudes, cannot be aligned with the front edge (dispensing opening) of the respective goods chute, but can be set back. This makes it possible, with proper support of the stack of goods and protection against manipulation, the stroke of the ejection element considerably shorter than the length of a package.
  • the output unit shown in FIG. 1 essentially consists of a block-shaped, module-like housing 1 in which drive means 2 are provided for an ejection element 4 which can be moved back and forth on the top 3 of the housing.
  • the dispensing unit is designed for assembly under a goods slot of a vending machine, the packs of goods stacked in the goods slot resting on the top of the dispensing unit.
  • the ejection element is provided with a front, protruding edge 5 which engages behind the bottom pack of the stack of goods and pushes out under the stack during the forward movement of the ejection element.
  • a support part 7 having a support surface 6 is provided on the front of the ejection element 4.
  • the support part is connected below the protruding edge 5 to the ejection element, specifically via a swivel joint 8.
  • the axis of the swivel joint is preferably set back by a small amount Y - with respect to the edge 5 of the ejection element - in order to clamp the ejected product pack the sliding packs of the pack to prevent stacks towards the end of the pushing out process.
  • the front end of the support part is provided with a protruding locking lug 9 which, when the ejection element is moved back, that is to say in the basic position of the dispensing unit, engages in front of the bottom goods package.
  • the support part itself is preferably subdivided again, and indeed a front part 10 is designed to be articulated by means of a swivel joint 11.
  • the ejection element 4 is shown in the front end position, ie in the position in which it is after pushing out a pack of goods, while in Fig. 2 the ejection element with the support part in the extended position, ie in the Basic position of the output unit is shown.
  • the support member 7 is folded down by about 45 degrees, wherein it is supported on an inclined surface 12 on the front 13 of the output unit.
  • the front part 10 of the support part hangs freely swinging downwards, the locking lug 9 being moved away from the pushed-out pack and the pack being able to slide down freely from the inclined support surface 6.
  • the modes of operation of the ejection element in connection with the support part and the sequence of a goods issue are explained below using the schematic representations of FIGS. 3 to 7.
  • the delivery unit is arranged below a goods chute 14, in which the product packs 15 are stacked, in such a way that the front side 13 of the output unit - with reference to the front side 16 of the goods chute - is set back. This enables the stroke of the ejection element 4 to be made shorter than it corresponds to the full length of a package of goods to be pushed out.
  • the shaft wall on the front 16 of the goods shaft 14 is shorter than the other shaft walls. in such a way that an output opening 17 is formed here which corresponds to the dimensions (width, height) of a package of goods to be pushed out.
  • the ejection element 4 of the dispensing unit is in its initial or rest position.
  • the support part 7, 10 is in a horizontally stretched position and the product packs 15 rest on it.
  • the bottom pack of goods is kept supported in full length.
  • the locking lug 9 of the support part protrudes in front of the bottom goods package and thus in or in front of the delivery opening 17. The delivery opening is thus blocked and no packs of goods can be manipulated out of it.
  • the drive means eg electric motor, gear, etc.
  • the ejection element 4 is advanced.
  • the front edge 5 engages behind the bottom pack of goods and pushes them forward, resting on the support part 7, 10.
  • the front part folds down and the locking lug 9 is moved away from the goods package.
  • the goods package itself is still pushed horizontally, the package being initially supported by the support part 7.
  • the swivel joint 8 of the support part 7 finally reaches the area of the front side 13 of the dispensing unit - the drive then being stopped - and folds down (FIG. 6).
  • This movement of the support part 7 is limited by the inclined surface 12, so that the support part is then in an inclined position of approximately 45 degrees.
  • the pack of goods located thereon then slides down from this area due to its own weight (FIG. 7) and is fed to a removal opening of the vending machine, which is not shown in any more detail here.
  • the pack of goods is pushed out from under the stack, the pack above it slides down so that it then lies on the ejection element.
  • the rear bevel 18 of the ejection element 4 ensures that this pack does not tip forward but always backwards so that it cannot slip through the discharge opening 17.
  • the support part 7 is first moved into its horizontal position, in which case a horizontal support surface that extends beyond the shaft area is immediately present, so that no goods packages are unwanted can slip out until finally the front part 10 pivots into its horizontal position and the locking lug 9 closes the discharge opening 17 of the goods chute again.
  • the directions of movement direction of motor rotation
  • stopping position / basic position of the ejection element, fill level control of the goods chute, etc. microswitches, light barriers or the like, which are known per se, are not shown here. Switching and control devices provided.
  • FIGS. 8A to 8C show an output unit arranged under a goods chute 14, in which a chain drive is provided for driving the ejection element 4.
  • a driver pin 20 is fastened to a horizontally rotating, endless chain 19 stretched between two sprockets, which dips into an elongated hole guide 21 of the ejection element and moves it back and forth as the chain rotates.
  • the ejection element which is guided in corresponding guides, therefore performs a forward and return stroke.
  • the speed of movement of the ejection element slows down when the ejection element approaches its reversing positions, and excessive movement of the ejection element or the support parts 7, 10 coupled to it is avoided, particularly at the front reversal point.
  • the chain is driven by one of the two sprockets, which is driven by an electric motor 22.
  • the motor always maintains its direction of rotation, only a "limit switch" is provided for recognizing the basic position of the output unit (corresponding to FIG. 3) and stopping the motor.
  • 9A to 9C show an output unit arranged under a goods chute 14, in which the ejection element 4 is driven by means of a “rack drive”.
  • a drive motor 23 is rigidly coupled to the ejection element and is moved back and forth together with it.
  • the motor is provided with a drive pinion 24 which meshes with a fixed rack 25.
  • a cam 26 attached to the motor 23 acts on a self-locking drag valve 27, the end 28 of which when the front reversing position is reached eg immersed in a light barrier 29 which controls the reversal of the direction of rotation of the motor.
  • the drag valve is designed so that it is only moved again when the motor or the ejection element has reached the basic position (corresponding to FIG. 3; 9A) at the end of the return stroke.
  • the motor is then switched off electrically, and at the same time its reverse direction of rotation is preselected / set for the subsequent forward stroke of the ejection element.
  • the advantage of such a slide valve is that its position / position that determines the direction of rotation is retained - even if there are interruptions in the power supply - until it is moved at the end of the stroke.
  • FIGS. 10A to 10C show an output unit arranged under a goods chute 14, in which the ejection element 4 is driven by a threaded spindle 31 driven by an electric motor 30.
  • the motor may have a corresponding reduction gear.
  • a spindle nut 32 "running" on the threaded spindle is firmly connected to the ejection element 4.
  • the motor is stopped or its direction of rotation reversed at the respective end or reversal points of the stroke of the ejection element. This is done similarly to the exemplary embodiment according to Fig. 9A - 9C via a slide valve 27 'in connection with a light barrier 29', with a molded on the spindle nut 32 approach or cam 26 'acts on the slide valve.
  • a so-called cross spindle or reversing spindle 33 known per se, as shown in FIG. 11, can also be provided. Due to the special design of the spindle, the direction of movement of the spindle nut 32 'is automatically reversed when the end positions 34, 35 are reached, without the direction of rotation of the spindle itself being changed.
