Definitions
- the invention relates to a device for collecting and optionally Blocking plastic bags provided with stacking openings with an impeller transfer device with wing arms projecting radially with respect to a circumferential axis as well as one driven in cycles around its own axis of rotation Collecting device with stacking strips, each of which corresponds to the stacking openings Stacking pins arranged in pairs are fastened in the plastic bags and also a removal gripper for stacked bag packages.
- DE 38 23 009 C2 discloses a stacking device for plastic bags one of the impeller transfer device downstream of the needle device Needle basket with a basket axis running parallel to the impeller axis and a plurality of needle bars arranged equidistantly parallel to the basket axis.
- stacking devices in the form of so-called pin stackers are known, as can be seen, for example, from DE 31 53 675 C2.
- Such pin stack conveyors Conventional types have a comparatively, sometimes at least 3 m long pen stacking section, in the area of the necessary handling, such as z. B. blocking of the bags, etc. can be performed.
- a stacking device of the generic type is known from DE 30 26 494-A.
- the device includes a transfer device with an impeller, the one in the essentially horizontally arranged revolving axis and radially projecting wing arms having.
- the collecting device contains a rotary table-like arrangement with support arms, on which collecting plates are arranged. The support arms rotate one indeed transverse to the axis of rotation of the transfer device, but vertically running Axis of rotation.
- DE 43 21 038-A1 describes a device for stacking plastic bags an impeller transfer device that includes a collection station operated by a Turning cross with axis of rotation and which runs essentially parallel to the impeller axis formed with a plurality of substantially horizontally projecting storage plates is.
- the storage plates take over on the side of the impeller transfer device Plastic bag from this until a predetermined stack height is reached. Subsequently the stacked plastic bags are placed on the side of the stacking station Pass the transfer position to a stacking plate with a bracket.
- the invention has for its object a collecting device of the generic type Way to create that at low cost by a comparatively small Space requirements, short format changeover times and a flawless Picking up the perforated plastic bags on the stacking pins of the stacking elements guaranteed.
- This object is achieved in that the axis of rotation of the collecting device essentially in the horizontal direction at about the same height as that Orbital axis of the transfer device is arranged and that the stacking elements as Stacking strips are formed on a common support arm around their hinge axis are cyclically driven in cycles like a paternoster and in the substantially parallel to the circumferential plane of the wing arms of the impeller of the transfer device extend.
- the collecting device and the transfer device are preferably each on one arranged its own, preferably movable support frame, and the stacked Bag packages are in the acceptance position of the collection device by Robot-controlled handling system removed.
- the device shown in the figures is used for collecting or stacking and if necessary blocking of plastic bags 1, which are not in one in detail bag making machines shown are generated. There are only one of these Preferred roller pair 2 and a separation welding device 3 are indicated schematically.
- An impeller transfer device 4 is arranged behind the automatic bag maker, which has an impeller 5 with a plurality of impeller arms 6.
- the impeller 5 is around a substantially horizontal axis of rotation 7 counterclockwise driven all round, as shown by arrow 8 concentric to
- the axis of rotation 7 is a bearing shaft 9 on which the individual wing arms 6 are attached.
- the impeller transfer device 4 has a support frame 11 which Can be moved at least in the direction of movement of the plastic bag 1 via rollers 12 is. If necessary, the support frame can also be adjusted transversely to the longitudinal direction be trained to easily adapt to different to be processed To enable plastic bags.
- a collecting device 13 is arranged behind the impeller transfer device 4, which also has a support frame 14 with its own rollers 15, so that the Support frame 14 independent of the support frame of the impeller transfer device Movable at least in the longitudinal direction, but possibly also displaceable transversely to it is.
- On the support frame 14 is a support arm 16 for the flying storage of Stacking strips 17 arranged, which have stacking pins 18 arranged in pairs. Their mutual distance corresponds to stack openings (not shown) in the Plastic bags 1.
- Via a drive not shown in detail, for example has a toothed belt or gear wheels 19, the stacking strips 17 revolving with the stacking pins 18 thereon in the manner of a paternoster drive.
- a drive motor 21 designed as a servo motor is used for the drive intended. From Figure 2 it can be seen that a about an axis of rotation 23 in the direction of Arrow 24 carrier cross 22 drivable cyclically in four positions is. In this way, the stacking bars 17 with the stacking pins located thereon 18 each in a transfer position I, one for blocking if necessary suitable intermediate position II and be moved to a removal position III.
- a Position 4 above is an empty position. In removal position III, the Bag packages, for example through a robot-controlled handling system, which in the Drawing is not shown.
