摘要:
An apparatus for unfolding folded plastic film having a first side joined to a second side along a longitudinal folded edge for use in forming a packaging tube. The folded film travels through a slot and the folded sides are separated at their respective outer longitudinal edges. The longitudinal left side is conveyed toward and over a guide plate left side edge and then over a left form tube section. The longitudinal right side is conveyed toward and over a guide plate right side edge and then over a right form tube section. The longitudinal middle section including the longitudinal folded edge and part of both the first and second sides adjacent the longitudinal folded edge is conveyed toward and over guide plate angular edges and then onto a carrying surface.
摘要:
A packaging apparatus including a receptacle, a ram, a film dispensing assembly and first and second elongate members. The receptacle defines a central axis and has a dispensing end with first and second substantially linear and parallel opposed edges that define an axial limit of the dispensing end. The plastic film material forms a film tube about the receptacle. The first and second elongate members are substantially parallel with the first and second edges. In operation, the ram is extended to eject the batch of material through the dispensing end into the film tube. Retracting the ram forms a partial vacuum within the film tube between the batch of material and the ram. The first and second elongate members compressively engage the film tube between the batch of material and the dispensing end and thereby form folded flaps in the film tube. A method of packaging is also disclosed.

An apparatus and method for dislodging a cotton sample from a side surface of a cotton bale includes an air nozzle fluidly connected to a supply of pressurized air. Conveyors and/or a ram transport the bale adjacent the nozzle. A quick release valve in line between the nozzle and the supply of pressurized air is selectively openable for directing a burst of air through the air nozzle to the side surface of the bale and thereby dislodging a cotton sample from the bale side surface. A sample intake opening is located adjacent the bale side surface and below the air nozzle. An air vacuum is fluidly connected to the sample intake opening whereby the dislodged cotton sample is sucked into the intake opening and transported to a sample collection receptacle.
摘要:
An apparatus for compressing a loose material that includes a compression chamber. Movement of a first ram discharges the loose material in a compressed state through an outlet port in the compression chamber. A packaging receptacle is positioned proximate the outlet port to receive the compressed material. The packaging receptacle is then moved to a second position where the movement of a second ram ejects the compressed material from the inner volume of the packaging receptacle. The second ram may be alternatively extended into and retracted from the packaging receptacle during ejection of the compressed material. The refilling of the compression chamber for the next cycle may begin prior to the retraction of the second ram from the packaging receptacle. A packaging jacket may be positioned about the packaging receptacle such that the ejection of the compressed material injects the compressed material into the packaging jacket.

An exemplary sample cutter is provided for preparing a sample of fibrous material. The sample cutter generally includes a base plate and a cutting mechanism extending from the base plate. The cutting mechanism includes at least one blade and at least one discontinuity. The at least one discontinuity has a total length less than 10% of a total perimeter of the cutting mechanism.
摘要:
Apparatus for vertically supporting and guiding a web of plastic film horizontally in applications such as in machines that form the plastic film into bags and fill the bags with bulk material. A longitudinally extending gap is provided between proximate edges of first and second plates. The plastic film web is traversed through the gap. A punch mechanism forms protrusions in the web. The protrusions slide atop the plates and prevent the web from falling through the gap as the web traverses through the gap. The protrusions can, for example, be tab cutouts with terminal ends sliding atop the plates and loops formed between slits extending to a crest.
摘要:
In an automated machine that forms a vertically positioned and horizontally traversing web of plastic film into bags and fills the bags with material, the apparatus opens the bags by separating the bag upper longitudinal edge portions. First and second opposing slide gates on opposite sides of the bags normal traversing plane are moveable between closed and open positions. Longitudinal channels on each of the slide gates receive and clampingly grip the bag longitudinal edge portions when the gates are moved away from their closed positions. The bag edge portions are thereby gripped and separated from one another when the gates are opened for thereby opening and filling the bags. While opening the gates, additional longitudinal edge portions are pulled into the apparatus and, while closing the gates, the additional edge portions are pulled out therefrom. The longitudinal edge portions freely traverse through the channels when the gates are closed.
摘要:
An apparatus for placing preformed bags having an open end and a closed end over an insertion tube for inserting a bale therethrough and into the bag. A plurality of fingers are inserted into the bag open end and are extended for engaging the bag. The fingers and bag opening are traversed to the tube thereby inserting the tube end into the bag opening. The fingers are retracted and removed from the bag. The insertion tube is expanded thereby engaging the interior surface of the bag. Roller drive wheels are placed on the bag over the insertion tube and are rotatably driven and are traversed along the insertion tube for collecting the bag thereon. The roller drive wheels and the plurality of fingers are carried on a common assembly movable along the insertion tube.

A bulk material leveling and volumetric measuring and feeding apparatus includes a conveyor for transporting bulk material from a hopper to a leveling assembly. The leveling assembly includes a pair of augers located perpendicular to the conveyor and with the auger terminal ends at a desired height from the conveyor. Side walls are provided parallel to the conveyor direction of travel and extend up to the auger terminal ends. Each auger is positioned within a semicircular longitudinal channel of a trough. Bulk material being transported and which is located above the augers terminal ends is lifted by the augers and thrown back towards the hopper. Thus, bulk material being transported under and beyond the leveling assembly is maintained at a desired depth. By monitoring and/or controlling the conveyor speed and the depth of the transported bulk material, the volumetric feed rate and total volume of transported material can be determined and/or controlled. The height of the leveling assembly above the conveyor is selectively adjustable. A shutoff gate is provided downstream of the leveling assembly.
摘要:
Apparatus for vertically supporting and maintaining a web of plastic film horizontally aligned in applications such as machines that form the plastic film into bags and fill them. Separate coplanar consecutively spaced plates are aligned with and extend through a web normal traversing plane. One of the plates has a peak edge extending out of the web normal traversing plane in a first direction, whereas another has a peak edge extending out of the web normal traversing plane in a second opposite direction. The peak edges define an undulating plastic film travel path between a web upstream location and a web downstream location. The web of film is tensioned between the upstream location and the downstream location and travels along the continuous undulating path. The film flexibly bends over the peak edges as a result of the tension and is thereby supported and maintained aligned.
