2. Description of the Prior Art
A conventional label stripping apparatus includes a housing, a reel support frame and a label stripping unit. The reel support frame is assembled in the interior of the housing for a label tape reel to be fitted thereon. The label stripping unit set at a front side of the housing contains a plurality of rods for a label tape on the label tape reel to be properly inserted thereon for facilitating stripping of labels of the label tape.
The reel support frame and a label stripping unit of the conventional label stripping apparatus are together assembled in the housing so it is quite inconvenient to repair the label reel and the label stripping apparatus. Further, since the reel support frame and the label stripping unit respectively have only one specification; therefore, a user cannot personally select and employ a label reel and label of a suitable length and size according to practical need. Furthermore, in a using or a winding process, the label tape on the label tape reel is apt to become slack and needs to be reset and repositioned. Thus, the conventional label stripping apparatus is very inconvenient to be employed and necessary to be ameliorated.
The objective of this invention is to offer an automatic label stripping machine, facilitating a user to get smooth labels for use automatically, quickly and conveniently and enabling a user to install easily label reels and labels of various types and different sizes.
The automatic label stripping machine in the present invention includes a base formed with a bottom plate having one side extending upward to form a side plate, which is perpendicular to the bottom plate. A reel shaft rod is horizontally fixed at one side of the side plate, corresponding to the bottom plate, and fitted thereon with at least one roller that has its outer side mounted with a first stop member. A label stripping unit is horizontally assembled at one side of the side plate, corresponding to the bottom plate, and is composed of a guide plate, a press plate, a guide stem and a winding shaft rod. The guide plate is rectangular, formed with an application portion and having its front end bent and formed with a bending portion with an internal angle less than 90 degrees, with the bending portion inserted out of the side plate. The press plate positioned above the guide plate is rectangular and has its front end bent to form a press portion with an internal angle less than 90 degrees. The press portion of the press plate is formed with a curved front end edge, and the press plate is slanting to a direction of the application portion of the guide plate to enable the press portion to push the application portion. The guide stem is fixed between the guide plate and the reel shaft rod. The reel shaft rod is formed with a main body, a fixing member and a power member, and has a toroidal surface radially recessed with at least two fixing grooves. The fixing members are U-shaped and formed with two fixing rods corresponding to the fixing grooves, and the reel shaft rod is connected with the power member. A control unit is installed at one side of the side plate, opposite to the bottom plate, and is electrically connected with the power member. A sensing unit is set at one side of the side plate, corresponding to the bottom plate, composed of a positioning rod, a positioning frame and a sensor. The positioning rod is fixed with the side plate, having another end connected with the sensor, which is provided in a direction toward the bending portion of the guide plate and electrically connected with the control unit.
To use the automatic label stripping machine of this invention, firstly, have a label reel fitted on the roller and then pull out the label tape and have the label tape passing through the guide stem and through a place between the guide plate and the press plate. Then, the label tape is inserted downward to pass through a space between the guide plate and the control unit and finally fixed on the winding shaft rod. Thus, the sensor can function to automatically detect a location of the bending portion of the guide plate to have the label stripped automatically, and the reel shaft rod can be employed for installing thereon with label reels and labels of various types and different sizes.
