Abstract

The tape dispenser has a housing accommodating a tape. The tape (1) consists of a carrier ribbon carrying a coating of a composition. The housing (4) also accommodates used carrier ribbon from which the composition has been removed. The supply of tape (1) is held in an elongated reel wound around a pair of spaced and independently rotatable spool members (2, 3).

Description

Tape dispensers

The present invention relates to a kind of Tape dispensers, wherein supply with a kind of coating composition to substrate surface to be applied that is carried on the checkrow, and this coating composition is transferred on the substrate surface as a continuous band when using this distributing box, and the carrier band is assigned with device and keeps here.This class Tape dispensers is known, and they for example are used to apply a kind of the correction and become to assign to cover a kind of write or print wrong and can correct.In these known corrected tape distributing boxs, supply reel separately and machine reel operated by rotary motion are in the distributing box box, and these two tep reels connect by a driver train, and when being pulled out for use from supply reel with the box lunch band, machine reel is rotated the carrier band of using to roll.Also have, when the rotative speed of two tep reels is inequality, need the clutch mechanism of certain form usually.Needs to power-transfer clutch have increased manufacturing cost, and this is disadvantageous, particularly plan to discard after the initial band of supplying with has used up because of most of distributing boxs.Because when all basically bands that begin to make and use are carried by supply reel, and supply reel is empty and all carrier bands all are wound onto on the machine reel when in the end using, so each tep reel requires sizable space in main distributor, this main distributor also is used for this distributing box of clamping during use as a handle.Thereby the strip length that can supply with in a distributing box is restricted, if main distributor is constant big, the result makes distributing box use trouble and inconvenience.Be desirable to provide a kind of distributing box with small elongate body or handle so that it can be to be similar to the occasion that the mode of holding one-pen or concentrator marker in hand is held, this shortcoming especially severe.

In order to alleviate above-mentioned shortcoming, the invention provides a kind of Tape dispensers, this distributing box comprises the main body of the band feedway of packing into, this band feedway comprises a carrier band, a kind of coating that is transferred into the composition on the substrate surface of this carrier band carrying, and be arranged at composition has been removed in storage from it the carrier band of using, wherein fix with the form of the elongated coil tep reel of reeling around a pair of spaced apart and independently rotary tep reel spare with feedway.

Bestly be, the two ends of carrier band are joined together, and are stored in the public volume tep reel with residue virgin tape with the carrier band of crossing.

By will with feedway remain on an elongated fixed reel for example each tep reel spare have in the oval fixed reel of same diameter, in an elongated distributing box box, can hold obviously more band than the band store arrangement of routine.And, by will with the carrier band of crossing be stored in one with the shared fixed reel of virgin tape in, needn't resemble the situation of prior art distributing box in the box that holds with the checkrow of mistake the extra space that separates is provided.If with a kind of continuous oval fixed reel, band is removed in the winding layer internally by this fixed reel, is used to be transported to an applicator head, and bring back to the carrier of crossing and to get back on the outmost winding layer then generation nature slip between the winding layer of fixed reel.Can rely on the rubbing effect of this slip to control to extend to applicator head or from the part that this applicator head is extended with tension force, thereby can exempt between each tep reel needs to driver train and clutch mechanism.The method of another kind of control belt tension is that tep reel so is installed, so that they can be movable relative to each other, and provides spring installation so that each tep reel is promoted separately.

For ease of more being expressly understood the present invention, illustrate in greater detail a specific embodiment with reference to the accompanying drawings, wherein:

Fig. 1 is the scheme drawing that the oval tep reel of band is shown,

Fig. 2 is the decomposition diagram of a kind of corrected tape distributing box of the present invention.

At first referring to Fig. 1, Fig. 1 illustrates a corrected tape fixed reel that is installed in the corrected tape distributing box.With 1 being known type, it comprises one section carrier band such as plastic tape or paper tape, is loaded with the correction composition on it, and this correction composition will be coated on the surface by this distributing box.According to the present invention, the two ends of this carrier band are spliced together, so this checkrow is a continuous ring, and this band is wound into the layer of some stacks around a pair of isolated equal diameter tep reel spare 2,3, thereby form the oval fixed reel of a band.As seen in Figure 2, this ellipse fixed reel is placed in the elongated box 4 of flat substantially, and as what be described in more detail below, interior winding layer and one section band between the outermost winding layer at each fixed reel are arranged to stretch out from box and be extended on the applicator head, and this applicator head is used for band is tightly suppressed substrate surface when using distributing box.As shown in Figure 2, box 4 is formed by two detail assemblys, and a pair of isolated axle 6,7 is bearing between these two parts, and two tep reel spares 2,3 are installed on this axle 6,7 separately, is used for around the independent rotation of axle separately.Applicator head 5 is stretched out and at its free end the tip 8 with edge 9 is installed from the front end of box, and band 9 passes through around the edge.Utilize a pair of pilot pin or deflector roll 10 to guide band into this tip and from this tip carrying-off.Tape drum can be regulated with respect to the applicator head pivoting, as patent application (the application number No of pending trial at us ...) described in.When band is pushed down a substrate surface by most advanced and sophisticated edge 9 and when should the tip moving on to this surface along the direction that is substantially perpendicular to this edge, is corrected applicator to be transferred on this surface from the carrier band, and coated as a kind of continuous bar.New band is pulled out from supply reel.In graphic device, new band is pulled out from the interior winding layer of the fixed reel of rearmost tep reel 3.In order to help band to separate from fixed reel, this tep reel 3 is preferably stipulated a kind of profile, so that it plays the effect of interior winding layer being shifted out the fixed reel plane.Band is separately walked around top tep reel 2 and was forwarded on pilot pin/deflector roll 10 before moving on the applicator tip 8.Around most advanced and sophisticated edge 9 by and from its remove the carrier band that corrects composition on moving near the fixed reel of the outermost winding layer of preceding tep reel 2 before, equally by a pair of pilot pin/deflector roll 10 guiding.When the light time is used in the supply of corrected tape, the oval fixed reel of band becomes the checkrow of being used gradually and replaces, and does not therefore need additional space in laying the box of this checkrow.

When band was transmitted by the interior winding layer from oval fixed reel, certain slip is moved and produced in each course the inside of outside between each adjacent layer.Can utilize friction between each sliding layer guarantee to obtain with in required tension force, the part that extends to applicator head or extend with control around this applicator head.Be readily appreciated that the amount that is contained in the band in the oval fixed reel of Fig. 1 is significantly greater than around the amount of a cylindrical tep reel with same number of plies storage.
