Abstract
A lower part 14L of a band way 14, which is incorporated in an arch unit 12, is separated from the other parts of the band way 14. A drive (air cylinder) 35 supports the lower part 14L, allowing the same to move between a substantially horizontal initial position and an inclined position. A band 13 is released from the band way 14 when a packing operation starts. Thereafter, the lower part 14L is moved from the initial position to the inclined position and compressed air is applied to the guide surface 14a of the lower part 14L, thereby removing foreign matter from the band way 14. This sequence of removing foreign matter is performed in, for example, each cycle of packing operation.
Claims17
A horizontal packing apparatus comprising:
- a body unit having a vertical table for supporting an article to be packed;
- a reel unit for holding bands;
- an arch unit straddling one side of the body unit and surrounding the vertical table;
- and
- a band way provided in the arch unit, defining a passage for a band fed from the reel unit, and having a lower part that can be disconnected from the other parts,
- wherein the band released from the band way is wrapped around the article supported on the vertical table, thereby to pack the article, and the arch unit includes drive means supporting the lower part of the band way and designed to move the same between an initial position that is substantially horizontal and an inclined position in which the lower part is inclined downwards.
A horizontal packing apparatus comprising:
- a body unit having a vertical table for supporting an article to be packed;
- a reel unit for holding bands;
- an arch unit straddling one side of the body unit and surrounding the vertical table;
- and
- a band way provided in the arch unit, defining a passage for a band fed from the reel unit, and having a lower part that can be disconnected from the other parts,
- wherein the band released from the band way is wrapped around the article supported on the vertical table, thereby to pack the article, the arch unit includes drive means supporting the lower part of the band way and designed to move the same between an initial position that is substantially horizontal and an inclined position in which the lower part is inclined downwards, and the body unit includes an automatic control circuit incorporating a program for automatically moving the lower part of the band way from the initial position to the inclined position and back to the initial position from the inclined position, at appropriate times during the packing operation.
A method of removing foreign matter from a horizontal packing apparatus that comprises a body unit, a table provided at a vertical side of the body unit, for supporting an article to be packed, an arch unit straddling one side of the body unit and surrounding the vertical table, and a band way for applying a band to the article, said method designed to remove foreign matter that has fallen from the article onto the band way and comprising the steps of:
- moving the lower part of the band way from an initial position that is substantially horizontal to an inclined position in which the lower part is inclined downwards, after a band is released from the band way and a packing operation starts;
- and
- moving the lower part of the band back to the initial position from the inclined position.
