Conveying apparatus and rotary type transfer apparatus for spout-equipped bags
First Claim
1. A rotary type transfer apparatus for spout-equipped bags in which said spout-equipped bags are received from a plurality of first spout holding members which are disposed on a circumference of a working rotor that rotates continuously at a constant speed, and said spout-equipped bags are rotationally conveyed and transferred to a rail type conveying apparatus installed on a downstream side of said rotary type transfer apparatus, said rotary type transfer apparatus further comprising:
- a transfer rotor which has a plurality of second spout holding members disposed on a circumference thereof, and a driving means which causes said transfer rotor to rotate intermittently at predetermined angle at a time in a predetermined cycle of stopping, acceleration, constant speed, deceleration and stopping, said driving means causing a speed of said second spout holding members during said constant-speed rotation to coincide with a speed of said first spout holding members and causes said first and second spout holding members to run side by side, wherein said second spout holding members receive said spout-equipped bags from said first spout holding members during said constant-speed rotation, and said spout-equipped bags are transferred from said second spout holding members to said rail type conveying apparatus provided on a downstream side at a predetermined stopping position of said second spout holding members.

Abstract
A rotary type transfer apparatus used in a continuous manufacturing apparatus for spout-equipped bags. The transfer apparatus includes a transfer rotor and a driving device and installed next to an extraction apparatus. The transfer rotor has spout holding members on its circumference, and the driving device causes the transfer rotor to rotate intermittently in a cycle of stopping, acceleration, constant-speed rotation, deceleration and stopping and causes the speed of the spout holding members of the transfer apparatus to coincide with the speed of the spout holding members of the extraction apparatus during the period of constant rotation and causes the spout holding members to run side by side. During the constant-speed rotation, spouts are transferred from the spout holding members of the continuously rotating extraction apparatus to the spout holding members of the rotary type transfer apparatus via a guide member.

11. A conveying apparatus for spout-equipped bags comprising a rotary type transfer apparatus and a rail type conveying apparatus wherein
said rotary type transfer apparatus comprises: -
a transfer rotor having a plurality of spout holding members disposed on a circumference thereof, said spout holding members being formed with holding grooves that are oriented radially outward and hold said spouts at grooves located between flanges formed on said spouts, a driving means which causes said transfer rotor to rotate intermittently a predetermined angle at a time, and a push-out device which, above said holding grooves, pushes said spouts out of said holding grooves of said spout holding members that are stopped at a predetermined stopping position by means of a pusher which advances and retracts in a radial direction of said transfer rotor; and
said rail type conveying apparatus is disposed on a downstream side of said rotary type transfer apparatus and is comprised of a transfer rail device that is disposed on a furthest upstream side of said rail type conveying apparatus as a part of said rail type conveying apparatus, said transfer rail device comprising;
transfer rails which are installed so as to be oriented radially outward from said stopping position and are used to receive spouts of spout-equipped bags from said holding grooves of said spout holding members stopped at said stopping position and transfer said spouts to a following rail type conveying apparatus, and a driving means which moves said transfer rails from a position where said transfer rails are installed to a retracted position in which said rails receive no spouts. - View Dependent Claims (12, 13, 14, 15, 16)
