A portable loader may be brought up to and selectively positioned to deliver product into mandrels carried by an automatic packaging machine. The loader may receive product on an asynchronous and on-demand basis and delivers product on a time basis coordinated with operation of the automatic packaging machine. The loader has two bins which are opened and closed in sequence to receive and deliver product with a buffer time storage in a second of the two bins in order to accommodate the timing of the packaging machine. The loader handles pouches and similarly irregularly shaped product, having a geometry which may vary at random. The pouches are gently shaped to fit into a box as they are transferred from a source of product into a loading position of the packaging machine.
A loader for feeding product into an automatic packaging machine, said loader being separate from said automatic packaging machine and comprising two bins, a conveyor operating on a first time basis for asynchronously delivering at least one product into a first of said bins, means for transferring said product from said first bin to said second bin for buffer time storage therein, and means for transferring said product from said second bin to said automatic packaging machine at a time which coincides with a second time base within which said packaging machines operate.
A method for loading irregularly shaped objects into an automatic packaging machine for packaging said objects into regularly shaped containers, said method comprising the steps of:
A loader delivery device for an automatic packaging machine, said device comprising a mounting means having on a front thereof, four positionally adjustable vertical side plates mounted thereon in two vertical pairs and four movable horizontal bottom blades positioned in pairs at the bottoms of each of said two vertical pairs in order to define two vertically aligned bins each having two side plates and two bottom blades, chart means on said front of said mounting means for indicating the adjusted positions of said side plates, and means for adjusting the positions of said side plates to positions indicated by said chart means.
A loader delivery device for an automatic packaging machine, said device comprising a mounting means having on a front thereof, four positionally adjustable vertical side plates mounted thereon in two vertical pairs and four movable horizontal bottom blades positioned in pairs at the bottoms of each of said two vertical pairs in order to define two vertically aligned bins each having two side plates and two bottom blades, said means for moving said horizontal bottom blades comprises two motors individually associated with said two bins, two rotary-to-linear motion converting means coupled to the pair of horizontal bottom blades of the bin which is individually associated with the respective ones of said two motors, and means for selectively operating said motors for controlling the positions of said bottom blades, one of said motors being associated with the other of said bins and operating under control of said automatic packaging machine.
