Abstract

An apparatus includes a fixed assembly and a reciprocating assembly. The fixed assembly includes a hopper, a first gas manifold, and a dispensing chamber, and the reciprocating assembly includes a channel assembly defining a channel conduit, a shield plate vertically aligned therewith, and a second gas manifold. The reciprocating assembly may move, in relation to the fixed assembly, to a first position to enable the channel conduit to be filled with bulk compressible material from the hopper, a second position to enable compressible material to be pushed from the channel conduit to the dispensing conduit and to be compressed in the dispensing chamber according to a first gas directed through the channel conduit by the first gas manifold, and a third position to enable the compressed material to be pushed out of the dispensing conduit according to a second gas directed through the dispensing conduit by the second gas manifold.

First claim

We claim:

1 . An apparatus, comprising:
a fixed assembly including a dispensing container, the dispensing container defining a dispensing conduit; and a reciprocating assembly including a first channel assembly, the first channel assembly defining a first channel conduit, the reciprocating assembly movable along a longitudinal axis between each position of a first position, a second position, and a third position in relation to the fixed assembly, wherein the apparatus is configured to
receive an amount of a bulk compressible material to form a first bulk instance of compressible material in the first channel conduit, based on the reciprocating assembly being at the first position,
direct a first gas into the first channel conduit to push a portion of the first bulk instance of compressible material from the first channel conduit into the dispensing conduit to form a first piece of compressed material within the dispensing conduit, based on the reciprocating assembly being at the second position, and
sever the first piece of compressed material in the dispensing conduit from remainder compressible material in the first channel conduit and direct a second gas into the dispensing conduit to push the first piece of compressed material out of the dispensing conduit, based on the reciprocating assembly moving from the second position to the third position.

2 . The apparatus of claim 1 , wherein the third position is between the first position and the second position along the longitudinal axis.

3 . The apparatus of claim 1 , wherein the first gas and the second gas are a same type of gas directed from a same gas source.

4 . The apparatus of claim 1 , further comprising:
a servomechanism configured to move the reciprocating assembly along the longitudinal axis between the first position, the second position, and the third position, and processing circuitry configured to
control the servomechanism to move the reciprocating assembly between the first position, the second position, and the third position,
control a first gas source to cause the first gas to be selectively directed into the first channel conduit in response to the reciprocating assembly being at the second position, and
control a second gas source to cause the second gas to be selectively directed into the dispensing conduit in response to the reciprocating assembly being at the third position.

5 . The apparatus of claim 1 , wherein
the reciprocating assembly includes a second channel assembly, the second channel assembly defining a second channel conduit; and the apparatus is configured to
receive a separate amount of the bulk compressible material to form a second bulk instance of compressible material in the second channel conduit, based on the reciprocating assembly being at the second position,
direct the first gas into the second channel conduit to push a portion of the second bulk instance of compressible material from the second channel conduit into the dispensing conduit to form a second piece of compressed material within the dispensing conduit, based on the reciprocating assembly being at the first position, and
sever the second piece of compressed material in the dispensing conduit from remainder compressible material in the second channel conduit and direct the second gas into the dispensing conduit to push the second piece of compressed material out of the dispensing conduit, based on the reciprocating assembly moving from the first position to the third position.

6 . The apparatus of claim 5 , wherein the apparatus is configured to
receive an additional amount of the bulk compressible material into the second channel conduit, subsequently to pushing the second piece of compressed material out of the dispensing conduit, based on the reciprocating assembly moving from the third position to the second position.

7 . The apparatus of claim 5 , further comprising:
a servomechanism configured to move the reciprocating assembly reversibly along the longitudinal axis between the first position, the second position, and the third position, and processing circuitry configured to
control the servomechanism to move the reciprocating assembly between the first position, the second position, and the third position,
control a first gas source to cause the first gas to be selectively directed into the first channel conduit in response to the reciprocating assembly being at the first position,
control the first gas source to cause the first gas to be selectively directed into the second channel conduit in response to the reciprocating assembly being at the second position, and
control a second gas source to cause the second gas to be selectively directed into the dispensing conduit in response to the reciprocating assembly being at the third position.

8 . A manufacturing system, comprising:
a conveyer belt, the conveyer belt including a loop of plates, each plate including a cavity; the apparatus of claim 1 , the apparatus on a section of the conveyer belt such that the apparatus is configured to push the first piece of compressed material out of the dispensing conduit concurrently with the dispensing conduit being vertically aligned with a first cavity of a first plate of the loop of plates such that the first piece of compressed material is received into the first cavity; and a packaging assembly configured to seal the first piece of compressed material in the first cavity in a package, wherein the conveyer belt is configured to discharge the package from the first cavity based on movement of the conveyer belt.

9 . A method of operating an apparatus, the apparatus including a fixed assembly and a reciprocating assembly, the fixed assembly including a dispensing container, the dispensing container defining a dispensing conduit, the reciprocating assembly including a first channel assembly, the first channel assembly defining a first channel conduit, the reciprocating assembly movable along a longitudinal axis between each position of a first position, a second position, and a third position in relation to the fixed assembly, the method comprising:
causing the reciprocating assembly to move along the longitudinal axis, in relation to the fixed assembly, to the first position to expose the first channel conduit to receive an amount of compressible material to form a first bulk instance of compressible material in the first channel conduit; causing the reciprocating assembly to move along the longitudinal axis, in relation to the fixed assembly, from the first position to the second position to expose the first channel conduit to the dispensing conduit; controlling a first gas source to cause a first gas to be directed into the first channel conduit concurrently with the reciprocating assembly being at the second position to push a portion of the first bulk instance of compressible material from the first channel conduit into the dispensing conduit to form a first piece of compressed material within the dispensing conduit; causing the reciprocating assembly to move along the longitudinal axis, in relation to the fixed assembly, from the second position to the third position to sever the first piece of compressed material in the dispensing conduit from remainder compressible material in the first channel conduit; and controlling a second gas source to cause a second gas to be directed into the dispensing conduit to push the first piece of compressed material out of the dispensing conduit, based on the reciprocating assembly moving from the second position to the third position.

10 . The method of claim 9 , wherein the third position is between the first position and the second position along the longitudin
