Abstract
A weighing and packing device for successively producing packages of product each of which is conformable with a predetermined weight condition. The device comprises a pair of combination weighing and packing machines mounted on a common frame as a single unit. Each machine includes a combination weigher and an associated packer which are mechanically interlocked so that the batches of product successively delivered from the combination weigher are packed by the packer in tubular bags fabricated successively from a sheet material. The combination weighers of both machines have their own control units electronically interlocked so that both machines can operate in mutually synchronized or nonsynchronized fashion with or without time lag.
Claims18
A weighing and packing device comprising:
- first and second combination weighers, each adapted to deliver batches of product, each batch having a total weight substantially equal to a target weight preset as an operating condition of each said weigher;
- first and second packers adapted to pack said batches of product delivered from said first and second combination weighers, respectively;
- control means for controlling operation of said first and second combination weighers and said first and second packers;
- at least one operation display means coupled to said control means for supplying operating conditions of said first and second combination weighers and said first and second packers and displaying operation data of said first and second combination weighers and said first and second packers;
- said control means adapted to operate said first and second combination weighers in a first mode in which said weighers operate synchronously to deliver said batches of product to their respective packers in first and second cycles, respectively, one cycle being a function of the other, and in a second mode in which said weighers operate nonsychronously to deliver said batches of product to their respective packers in first and second cycles, respectively, which are independent of each other;
- and
- said control means includes means for selecting one of said first and second modes of operation in accordance with said operating conditions supplied from said operation display means.
A weighing and packing method for use with first and second combination weighers, each adapted to deliver batches of product, each batch having a total weight substantially equal to a target weight preset as an operating condition of each said weigher;
- first and second packers adapted to pack said batches of product delivered from first and second combination weighers, respectively;
- and at least one operation display means for supplying operating conditions of said first and second combination weighers and said first and second packers and displaying operation data of said first and second combination weighers and said first and second packers;
- said method comprising the steps of:
- operating said first and second combination weighers in a first mode in which said weighers operate synchronously to deliver said batches of product to their respective packers at first and second cycles, respectively, one cycle being a function of the other, and in a second mode in which said weighers operate nonsynchronously to deliver said batches of product to their respective packers at first and second cycles, respectively, which are independent of each other;
- and
- selecting one of said first and second modes of operation in accordance with said operating conditions supplied from said operation display means.
