Definitions
- This invention refers to a linear motion device for the automatic ejection of individual filter bags originating from the work stations of a packaging machine and presenting some packaging defects such as to render them unacceptable by the consumer and prevent their usage for a further assembling phase in containers such as carton boxes and the like
- This device find s particular application in the packaging machines for filter bags for tea, camomile-tea herbs etc , where the individual filter bags may present packaging defects such as missing some packaging elements including the label, the tea in the bag, the handling thread, etc
- the mentioned filter bags may be of the dual-lobe type, meaning with a dual chamber with the bellows on bottom, or of the single lobe type, which are generally completed by associating them with a pick-up label and a handling thread by some well known anchoring methods (metal clasp, thermally welded stamp, sewing, knotting, simple thermal welding with the filter paper, etc ), or may be filter bags without a thread and label, of various forms (square, rectangular, round etc ) All these bags may accumulate particular defects, at the
- the filter bags are, for a better protection of their infusion material content, generally packaged inside an outer bag of ordinary or thermally welded paper known as a cover bag.
- a cover bag In the case of a defective filter bag, the present packaging machines equipped as above fail to prevent, as it would be desirable, the feeding and packaging of the cover bag but are, despite the memorization of the defective bag and therefore the certainty of a final rejection, still allowing the filter bag to be inserted into its cover bag, with an additional wastage of material and high production costs.
- the device (2) comprises a single work station constituted by a first receiving seat (6a) of a bag (7) equipped with two lateral half plates (8) supporting the bag (7), capable of moving at an angle and rotating around themselves in accordance with a preset angular shift around a fulcrum (9) having an axis essentially parallel to the longitudinal direction of the two half plates (8)
- the angular opening of the two half plates (8) is controlled, while rotating around the fulcrum (9), by a drive separate from that of the pusher, so as to allow them to open only when needed
- the device (2) also comprises a second seat (6b) for receiving a bag (7) coming from the seat (6a), where said
- RECTIFIED SHEET (RULE 91) seat (6b) is fitted with a surface opening essentially identical to the size of the filter bag (7) and capable of introducing individual filter bags (7) into the subsequent counting and assembling station (5)
- the pincers (4) extract the individual filter bag (7) from the packaging machine (1 ) and place it next to the seat (6a), where a first compactor (10) angularly rotating around its axis y-y takes care of pressure- positioning the filter bag (7) on the half plates (8) facing a pusher (11 ) which shifts the filter bag (7) with a linear motion "X" to its subsequent seat (6b), where a second compactor (12) takes care of introducing it into the subsequent counting and assembling station (5)
- an electromechanical device controls the angular opening of the two half plates (8) around their respective fulcra (9), so that the compactor (10) manages, while pressing down on the filter bag (7), to eject the same through an opening provided below the two half plates (8), as may more easily be seen in Figure 2, thus preventing the pusher (11 ), which is at any rate intermittently pursuing its shifting motion with every machine cycle, from conveying the defective bag into its seat (6b)
- the filter bag does not have any packaging defect, it is backed up, with the aid of the compactor (10), on the two normally closed half plates (8), where the pusher (11 ) takes care, by its cyclically intermittent shifting motion (X), of pushing it ower to its subsequent seat (6b), where the compactor (12) can introduce it into the counting and assembling station (5)
- the device (2) is also capable of receiving the packaged filter bag in a paper envelope
- the pincers (4) extract the cover bag containing the filter bag from the top (1 ).
- the device (2) allows receiving only cover bag packages in its seat (6a), whose internal filter bags are entirely fault-free.
- a conventional electromechanical device associated with the device (2) prevents the paper lobe of the cover bag from being cut off and inserted into the pincers at the top (1), so as to prevent it from being uselessly packaged together with the filter bag (7) already destined to be ejected from the device (2).
- the device (2) has also been designed so that during all the extracting operations (3) of the filter bag and its linear shifting (X) by the pusher (11 ), all the devices characterizing the mentioned operations take care of uniformly distributing, in a dual (longitudinal and transversal) direction with respect to the axis of the bag, the incoherent product contained in the bag and volumetrically displaced to the bottom of the bag during its packaging position at the top 1 ).
- the extraction pincers (4) are in fact conveying the bag (7), at the point of its stop in the position (13), against the vertical wall of the fixed plane 814), thus causing, as a result of the known effects of inertial forces, the forced longitudinal sliding of the product from the bottom X to the top D of the bag.
- the pusher (11 ) causes the bag (7) to linearly shift at high speed in the direction (C), thus conveying it at the end of its run against the vertical wall of the additional fixed plane (15), thus inducing the forced shifting of the product, because of the usual inertial effects, in a transversal direction E-F with respect to the bag's longitudinal axis C-D.
- the above invention is obviously susceptible of undergoing numerous modifications and variants suggested by its practical application, its execution and usage, all of which are however falling within the scope of the following claims.
