The invention concerns a method for feeding chips into a chip bin or corresponding, the chips in said method being forced to move substantially horizontally as a plug filling the cross-section of the transfer space. The chip plug is formed and maintained at a part of the length of the transfer space with chips forced batchwise to the transfer motion.
Description
The invention is described in more detail in the following, with reference to the enclosed drawing, wherein
FIG. 1 shows a schematic drawing of the feeding apparatus in accordance with the invention, as a cutaway side view, and
FIG. 2 shows a cutaway perspective view of the apparatus.
Claims
1. A method for feeding chips into a chip bin or a corresponding vessel, the chips in said method being forced to move substantially horizontally as a plug along a transfer space, the space having a length and a cross-section, and an inflow at one end of the length as well as an outflow at the opposite end of the length, wherein the chip plug is formed and maintained at the inflow by subjecting a reciprocating pushing action in the transfer direction on the chips, using a stroke for the reciprocating pushing action reaching to a distance in the transfer direction, which distance is a minor part of the length of the transfer space.
2. A feeding apparatus for feeding chips into a chip bin or a corresponding vessel, said apparatus comprising an essentially horizontal chip transfer channel having a length, a cross-section, an inflow end and an outflow end, a chip inlet connection opening to the transfer channel at the inflow end, elements for transferring the chips in the transfer channel from the inflow end to the outflow end, and a discharge connection leading at the outflow end from the transfer channel to the chip bin or a corresponding vessel, wherein the chip transfer elements are pushing means located at the inlet connection, the pushing means being equipped to perform a reciprocal movement in the length direction of the transfer channel, and the length of stroke of the pushing means being a minor part of the length of the transfer channel.
3. A feeding apparatus in accordance with claim 2, wherein the stroke length of the pushing means is ⅕ to ⅓ of the length of the transfer channel.
4. A feeding apparatus in accordance with claim 2, whereby the pushing means are arranged to operate substantially to cover the total cross section of the transfer channel.
5. A feeding apparatus in accordance with claim 4, wherein each pushing means is arranged to operate in a separate compartment extending along the length of the transfer channel and having substantially the width of the pushing means.
6. A feeding apparatus in accordance with claim 3, wherein the pushing means are arranged to operate substantially to cover the total cross section of the transfer channel (1).
7. A feeding apparatus in accordance with claim 2, wherein the pushing means are arranged to operate out of phase with each other.
8. A feeding apparatus in accordance with claim 3, wherein the pushing means are arranged to operate out of phase with each other.
9. A feeding apparatus in accordance with claim 4, wherein the pushing means are arranged to operate out of phase with each other.
10. A feeding apparatus in accordance with claim 5, wherein the pushing means are arranged to operate out of phase with each other.
11. A feeding apparatus in accordance with claim 6, wherein the pushing means are arranged to operate-out of phase with each other.
