Abstract
A device for automatically stripping and delivering a fore end of a paper roll, in which the fore end of the paper roll, which is wound on a bobbin, is gripped by both a stripping lever and a pawl member when the paper roll fore end gets on the fore end portion of the stripping lever, the stripping lever being capable of coming into contact with and moving away from the paper roll, the pawl member being mounted on a fore end side of the stripping member so as to be capable of coming into contact with and moving away from the fore end of the stripping member. The fore end of the paper roll after being stripped and drawn out by both the stripping member and the pawl member is sucked and delivered to the next step.
Claims6
A device for automatically stripping and delivering a leading end of a paper roll, said device comprising:
- a stripping lever having a fore end movable into and out of contact with the paper roll;
- a bobbin driving means for rotating a bobbin with the paper roll wound thereon so that the leading end of the paper roll is rotatable into contact with a fore end portion of said stripping lever;
- a pawl member mounted on said stripping lever for movement into and out of contact with the fore end of the stripping lever to grip the leading end of the paper roll conjointly with the fore end of the stripping lever when the paper roll leading end is in contact with the fore end of the stripping lever;
- a stripping lever driving means for moving said stripping lever into a first position in abutment with the paper roll and pivoting the stripping lever away from the paper roll into a second position after gripping of the leading end of the paper roll by both the stripping lever and said pawl member occurs;
- a sucking and delivering means for sucking the leading end of the paper roll after it is stripped and drawn out away from the roll by both said stripping lever and said pawl member into said second position to enable transferring movement of said leading end from the stripping lever and pawl member to another location;
- and
- a stationary base plate to which the stripping lever, bobbin driving means, pawl member, stripping lever driving means and sucking and delivering means are mounted, said first and second positions lying along an arcuate path along which the fore end of the stripping lever moves.
A device for automatically stripping and delivering a leading end of a paper roll, said device comprising:
- a stripping lever having a fore end movable into and out of contact with the paper roll;
- a bobbin driving means for rotating a bobbin with the paper roll wound thereon so that the leading end of the paper roll is rotatable into contact with a fore end portion of said stripping lever;
- a pawl member mounted on said stripping lever for movement into and out of contact with the fore end of the stripping lever to grip the leading end of the paper roll conjointly with the fore end of the stripping lever when the paper roll leading end is in contact with the fore end of the stripping lever;
- a stripping lever driving means for moving said stripping lever into a first position in abutment with the paper roll and pivoting the stripping lever away from the paper roll into a second position after gripping of the leading end of the paper roll by both the stripping lever and said pawl member occurs;
- a sucking and delivering means for sucking the leading end of the paper roll after it is stripped and drawn out away from the roll by both said stripping lever and said pawl member into said second position to enable transferring movement of said leading end from the stripping lever and pawl member to another location;
- and
- a stationary base plate to which the stripping lever, bobbin driving means, pawl member, stripping lever driving means and sucking and delivering means are mounted, wherein said stripping lever is pivotally secured at one end thereof to the plate and projects towards the paper roll for tangential contact therein upon being pivoted into an upper position, said pawl member being mounted to the lever fore end at a mid-section of the pawl member for pivotal movement thereabout, and a spring connecting a rear end of the pawl member to a mid-portion of the lever to bias the forward end of the pawl member away from the corresponding forward end of the lever.
