Abstract
A pneumatic labelling apparatus including a portable base frame having a unitary handle member, in which the base frame includes a magazine for supporting a roll of separable label carrying web material, a web entraining device guiding the web from the magazine past a dispensing station, where each label is separated from the backing web, and then about a web feeding device. The web feeding device is sequentially actuable by a ratchet and pawl mechanism in which the pawl is reciprocably mounted upon a movable frame member within the base frame and operatively connected to the piston rod of a fluid-actuated cylinder within the handle member. The piston rod is actuated by a trigger and a control valve in a fluid circuit connected to the fluid-actuated cylinder.
Claims8
A labelling apparatus comprising:
- (a) an elongated base frame having front and rear end portions,
- (b) magazine means on said base frame for receiving an elongated web carrying serially a plurality of peelable adhesive labels,
- (c) a web entraining device on said base frame for guiding the web from said magazine means to a dispensing station where the labels are sequentially removed from the web, and then to a web feeding station,
- (d) a web feeding device at said web feeding station, operable to move a web through said web entraining device,
- (e) a movable frame member,
- (f) means mounting said movable frame member on said base frame for movement relative to said base frame,
- (g) a feed actuator element carried on said movable frame member in operable engagement with said web feeding device for actuating said web feeding device upon movement of said feed actuator element,
- (h) a handle member fixed to the rear portion of said base frame,
- (i) a fluid-actuated cylinder mounted on said handle member and having a reciprocable piston rod,
- (j) means connecting said piston rod to said movable frame member for movement of said movable frame member with said piston rod,
- (k) fluid circuit means mounted on said handle member and in fluid communication with said cylinder and a fluid supply,
- (l) a control valve member in said fluid circuit means for controlling the flow of fluid to said cylinder, and,
- (m) a trigger on said handle member and operatively connected to said control valve member for actuating said piston rod to reciprocably move said movable frame member to cause incremental feeding of a web in said web entraining device.
