Concrete form of implementation

Below, for best form of implementation of the present invention, describe with reference to accompanying drawing.

In addition, Fig. 1 is the instruction diagram of the spool summary of this form of implementation of expression.Fig. 1 (a) is a front elevation, and Fig. 1 (b) is an A-A line section-drawing among Fig. 1 (a).

The formation of spool 1 shown in Figure 1 comprises: columned reeling end 3, and clip this reeling end 3 parallel or substantially parallel pair of

side plates portions

2,2 of relatively installing.In addition, in the substantial middle of spool 1, be provided with the axis hole 4 of D hole shape with connecting.Insert the winding off spindle of logical not shown batch up gear by this in this hole 4, spool 1 is installed on this batch up gear, the driving that is accompanied by winding off spindle is rotated.

The spool 1 of Gou Chenging like this, the membraneous material that is used for will coating forming bond layer cuts into banded in a narrow margin and reels, and makes and supplies with under the situation of various splicing tape 5 these splicing tapes 5.The width of reeling end 3 promptly, the distance between the

side plate

2,2 that separates by reeling end 3, can be corresponding to suitably setting as the splicing tape 5 cut-out width that batched thing.In addition, in general, side plate 2 forms discoideus, but its diameter can suitably be set corresponding to the length of batching of splicing tape 5.

In this form of implementation, though spool 1 can be integrally formed by injection moulding etc.,, also pair of

side plates portion

2,2 and reeling end 3 can be formed separately, it is bonded into one by suitable mode such as chimeric, bonding.If

side plate

2,2 and reeling end 3 are formed separately, for example, by public reeling end 3, side plate 2 and these reeling end 3 combinations with different-diameter, can be adapted to the various length of batching, perhaps that width is

different reeling ends

3 and 2 combinations of public side plate can be adapted to various cut-out width.

In addition, in this form of implementation, on the medial surface of

side plate

2,2, be provided with Fig. 1 (b) and shown in Figure 2 at the protuberance 21 that radially extends.

In addition, Fig. 2 is the end view drawing of the B-B section of presentation graphs 1 (b).

Be arranged on the protuberance 21 on the medial surface of side plate 2, when being wound on splicing tape 5 on the spool 1, perhaps carrying out under the situation of batching keeping of splicing tape 5, can be suppressed at the contacting of medial surface (medial surface of side plate 2) of the bond layer that the side of splicing tape 4 exposes and spool 1, like this, can prevent to form on the medial surface of lining cement attached to spool 1 of bond layer.

In other words, distance between the

side plate

2,2 that separates by reeling end 3, set for to have and cut off the affluence to a certain degree of width corresponding to splicing tape 5, in order to avoid the splicing tape 5 that is wound on the reeling end 3 contacts with the medial surface of side plate 2, but, when carrying out the coiling of splicing tape 5, rock the impact that waits when making the winding position deflection of splicing tape 5 or batching keeping and vibration etc. when causing the splicing tape 5 generation location dislocations of coiling when the rotation of spool 1 produces, splicing tape 5 will contact with the medial surface of side plate 2.

In this form of implementation, even in this case, the area of contact of the medial surface by protuberance 21 being set, can dwindling the bond layer that exposes in the side of splicing tape 5 and side plate 2 on the medial surface of side plate 2 prevents to form on the medial surface of lining cement attached to spool 1 of bond layer.

In this form of implementation, when this protuberance 21 was set, the height h1 of preferred protuberance 21 was 0.05～1.00mm, more preferably 0.05～0.30mm, preferred especially 0.05～0.20mm.

When the height h1 of protuberance 21 deficiency 0.05mm, be difficult to obtain to suppress the effect that splicing tape 5 contacts with the medial surface of side plate 2.In addition, this also is disadvantageous on the one hand for the condition management precision that needs for spool 1 injection moulding the time.On the contrary, when the height h1 of protuberance 21 surpassed 1.00mm, protuberance 21 was too high, can influence the width dimensions of spool 1.In addition, make the pushing grow of 5 pairs of sides of splicing tape, the vestige of protuberance 21 might be attached to the side of splicing tape 5, this is disadvantageous.

In addition, the height w1 of preferred protuberance 21 is 0.5～20.00mm, more preferably 0.5～10.0mm, and preferred especially 0.5～5.0mm,

When the width w1 of protuberance 21 deficiency 0.5mm, might damage the side of splicing tape 5.In addition, this also is disadvantageous on the one hand for the condition management precision that needs for spool 1 injection moulding the time.On the contrary, when the width w1 of protuberance 21 surpasses 20.0mm, can produce the problem that lining cement adheres on protuberance 21.

In addition, in this form of implementation, as shown in Figure 1, a plurality of (being 8 in illustrated embodiment) protuberance 21 of radially extending during with radial the setting, can be prevented to form on the medial surface of lining cement attached to spool 1 of bond layer more reliably.

In addition, in this form of implementation, the medial surface along circumference of side plate 2 is provided with Fig. 1 (b) and the periphery protuberance 22 along the circumferencial direction extension shown in Figure 3.

In addition, Fig. 3 is the end view drawing of the C-C section of presentation graphs 1 (b).

At this, to cut in a narrow margin splicing tape 5 when being wound on the spool 1, shown in Fig. 4 (a), bevelled is simultaneously slightly making splicing tape 5, when under the state that the circumference with side plate 2 leads to the side of splicing tape 5, reeling, with the alignment of the side of splicing tape 5, can reel not producing under the even prerequisite of cinch.

In addition, Fig. 4 is the instruction diagram of the state that batches of expression splicing tape 5.In addition, Fig. 4 (b) is the left surface figure of state shown in Fig. 4 (a), coiling splicing tape 5 on the spool 1 of the rotation of the direction of arrow in figure.

In this form of implementation, be arranged on the periphery protuberance 22 on the medial surface of circumference of side plate 2, as mentioned above, when being wound on splicing tape 5 on the spool 1, the bond layer that exposes by the side that makes splicing tape 5 contacts with the circumference of side plate 2, can prevent to form on the circumference of lining cement attached to spool 2 of bond layer.

In other words, in this form of implementation, when being led in the side of splicing tape 5 with the circumference of side plate 2, in order to dwindle the area of contact with splicing tape 5, side plate 2 on the medial surface of circumference, be provided with the periphery protuberance 22 that along the circumferential direction extends, therefore can prevent adhering to of lining cement.

Thereby, periphery protuberance 22 preferably, the contact site of itself and splicing tape 5 is made circular-arcly at least, its radius of curvature is on the basis that can dwindle with the area of contact of splicing tape 5, it is proper to get 0.3～1.5mm, preferably 0.5～1.0mm.

In addition, in this form of implementation, when above-mentioned periphery protuberance 22 was set, the height h2 of preferred periphery protuberance 22 was 0.05～1.00mm, more preferably 0.05～0.30mm, preferred especially 0.05～0.20mm.

When the height h2 of periphery protuberance 22 deficiency 0.05mm, impair and suppress the effect that splicing tape 5 contacts with the medial surface of side plate 2.In addition, when carrying out the coiling of splicing tape 5, protuberance 21 is interfered with splicing tape 5, can damage splicing tape 5, and this is disadvantageous.On the contrary, when the height h2 of periphery protuberance 22 surpassed 1.00mm, periphery protuberance 22 was too high, when carrying out the coiling of splicing tape 5, can interfere with splicing tape 5.In addition, because splicing tape 5 after the coiling splicing tape 5 and the gap between the

side plate

2,2 become big, so the volume dislocation in the time of might producing keeping etc. cause keeping stability to reduce, this is disadvantageous.

In addition, the width w2 of preferred periphery protuberance 22 is 0.5～20.0mm, more preferably 0.5～10.0mm, most preferably 0.5～5.0mm.

When the width w2 of periphery protuberance 22 deficiency 0.5mm, might damage the side of splicing tape 5.On the contrary, when the width w2 of periphery protuberance 22 surpasses 20.0mm, can produce the problem that lining cement adheres on periphery protuberance 22.In addition, when unreeling and using the splicing tape 5 that is wound on the spool 1, splicing tape 5 might be hung on the periphery protuberance 22, this is disadvantageous.

More than, for the present invention, show best form of implementation and be illustrated, still, the present invention is not limited to above-mentioned form of implementation, and is self-evident, can also make various change forms of implementation within the scope of the invention.

For example, in above-mentioned form of implementation, on the both sides of pair of

side plates

2,2, be provided with radial lugs 21 and periphery protuberance 22, still, radial lugs 21 and periphery protuberance 22 can also only be arranged on the side plate 2 as required.

In other words,, between opposite side board 2 and splicing tape 5, keep gapped words, also can only on this another side plate 2, radial lugs 21 and circumferential protuberance 22 be set if near side plate 2 one side coiling splicing tapes 5.

In addition, in above-mentioned form of implementation, illustrate example as the axis hole 4 of D hole shape, but, also can make the shape that forms keyway corresponding to the key that is arranged on winding off spindle one side, the concrete form of axis hole 4 can carry out suitable change according to the device of installing on the winding off spindle of batch up gear.

In addition, in above-mentioned form of implementation, though show the form of reeling end 3 briefly,, also can be provided for guaranteeing the rib of rigidity etc., adopt various forms applicable to this spool.

In addition, in above-mentioned form of implementation, splicing tape 5 conducts that comprise bond layer are by the coiling thing, but, spool of the present invention, generally speaking, be applicable to that preferably the quilt that possesses the bond layer that uses the coated formation of material that is called lining cement batches thing, can prevent adhering to of lining cement.

In addition, in above-mentioned form of implementation, be arranged on the protuberance 21 on the medial surface of side plate 2, the raised line that forms continuously as interior all side direction outer circumferential sides and being provided with from spool 1, still, protuberance 21 also can form shown in Fig. 5 (a) intermittently.Moreover protuberance 21 is except with being provided with along the direction of mind-set periphery from side plate 2 in the mode of radially extending, both can be shown in Fig. 5 (b), and with radially arranged in a crossed manner, also can be shown in Fig. 5 (c), with the curve-like setting.

In addition, under with the situation of protuberance 21 with radial setting, its emission center is preferably consistent with the center of side plate 2, still, also can be arranged to inconsistent form as required.Moreover, also can be from each centers of a plurality of different emission centers with radial expansion protuberance 21 is set.

In addition, the section shape of protuberance 21 also is not limited to above-mentioned circular-arc, can be rectangle or with the shape of its bight chamfering, also can make section shape as shown in Figure 6.

Like this, be arranged on the number of the protuberance 21 on the medial surface of side plate 2 or shape etc., the form that it is concrete as long as can prevent lining cement adhering on the medial surface of spool 1, is not particularly limited.

Equally, being arranged on the periphery protuberance 22 on the medial surface of circumference of side plate 2, as long as when the circumference with side plate 2 leads and reels the side of splicing tape 5, can preventing that adhering to of lining cement is just passable, can be various distortion forms of implementation.

In above-mentioned form of implementation, periphery protuberance 22 is being provided with along the circumference of side plate 2 in full week, still, for example also can be, shown in Fig. 7 (a), is being provided with intermittently along the circumference of side plate 2.In addition, also can shown in Fig. 7 (b), make shape, or shown in Fig. 7 (c), a plurality of (in illustrated embodiment, being two) periphery protuberance 22 is being arranged side by side with the curve-like bending.

Moreover, shown in Fig. 8 (a)～(c), also can with the periphery protuberance 22 that is provided with intermittently with in order to prevent that lining cement from adhering to set protuberance 21 to the medial surface of spool 1 and being connected.

The section shape of periphery protuberance 22 can be circular-arc a, rectangular shape or with the shape of its bight chamfering, moreover, can also be section shape as shown in Figure 6 etc., also can make the section shape same with the section shape of protuberance 21.

At this, Fig. 5,7, the 8th represents the instruction diagram of the configuration of the

protuberance

21,22 in the above-mentioned variation conceptually.In addition, Fig. 6 is the instruction diagram of summary of the section shape of expression protuberance 21 (or periphery protuberance 22).Fig. 6 (d), (f) are that the example shown in Fig. 6 (e), (g) is provided with two protuberances 21 (or periphery protuberance 22) under the bonded assembly state abreast with the close example that is arranged side by side of two protuberances 21 (or periphery protuberance 22).
