Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a handrail packing drum. More specifically, the present invention relates to a handrail packing drum capable of wrapping and packing a long endless handrail.

[Prior Art] Handrails are used as endless moving handrails on escalators and auto lines. Escalators and auto lines are used in department stores, hotels,
They are used by an unspecified number of passengers at stations, etc., and are required to be elegant, safe, and durable at all times.

Escalator handrails installed in department stores, hotels, etc. are relatively short, whereas autoline handrails installed in airports, exhibition halls, etc. are relatively long.

Short handrails are connected endlessly during factory production before being packed and shipped. On the other hand, long autoline handrails were manufactured without endless connections at the factory, and were shipped after being packed, and endless connections were made on site.

However, when connecting in a distant place, for example in a foreign country, the burden of personnel costs, accommodation costs, travel expenses, tool transportation costs, etc. for the connection workers is large, and delays in the installation period are unavoidable due to the number of days required for connection.

Now, as shown in Figure 4, the handrail is a laminate of roughly C-shaped soft rubber with a hollow groove and thick woven canvas, so the most important point during packing work is that it can be packed without deforming it. It is.

Generally, there are two methods for packing handrails: a boxing method and a drum wrapping method.

First, since the box packing method involves folding the handrail several times into a box of a certain size, this method inevitably causes deformation of the handrail and the occurrence of bending cracks.

On the other hand, the drum wrapping method for packing is a method in which a handrail 4 is wrapped around a packing drum 3 consisting of a body section 1 and a collar section 2 as shown in FIG. In the example shown in FIG. 1, the wrapped handrail 4 is not connected endlessly. Although this method avoids bending cracks in the handrail, deformation is unavoidable when a long endless handrail is wrapped and packed.

That is, when the long endless handrail 4 is wrapped around the conventional drum 3 and packed as shown in FIG. This results in a state in which the winding is standing in a vertical direction, and as a result, the winding start portion is inevitably compressed and deformed by sequentially overlapping the winding.

In this case, as shown in FIG. 4, a method of winding the material around the drum without having a C-shaped cross section may be considered. However, in order to adopt this method, the wrapping width (2,
2) would require the provision of extremely large drums, which would also be impossible due to drum manufacturing costs and transport obstacles.

[Problem to be solved by the invention] The present invention has been made based on the above points, and its purpose is to eliminate the drawbacks of the prior art described above and to transform the long endless handrail. To provide a handrail packing drum that can be wrapped and packed without causing any damage.

[Means for Solving the Problems] The gist of the present invention is to provide a handrail packing drum having disk-shaped flanges at both left and right ends of the body, in which a handrail is provided on the circumferential surface of the body. A pair of mounting jigs with approximately wedge-shaped cross sections in the circumferential direction are provided for hooking the folded part of the body. The grooves are enlarged and formed into an arc shape to define a substantially U-shaped handrail storage groove between them, and the thickness is gradually reduced from the facing wall to the other end edge of each. and forming an inclined surface extending in the tangential direction of the body.

[Function] The handrail packing drum of the present invention has a pair of mounting jigs each having a wedge-shaped cross section in the circumferential direction for hooking the folded part of the handrail on the circumferential surface of the body. On the circumferential surface of the body of the tool, the facing walls are the largest in thickness and are formed in an arc shape to define a substantially U-shaped handrail storage groove between them, and the opposing walls By gradually decreasing the thickness from the side wall to the other end edge side and forming an inclined surface extending in the tangential direction of the body, the part after the folded part of the endless handrail stands in a C-shaped cross section. The reason is that the bag gradually changes from a flat state to a flat state so that it can be smoothly wrapped and packed.

That is, the handrail packing drum of the present invention is
This makes it possible to wrap and pack the endless handrail without deforming the folded part, which is the most problematic part of wrapping and packing endless handrails, and also effectively prevents pressure deformation and bending of the protruding part that occurs when wrapped in layers. As a result, an elegant and durable endless handrail can be quickly supplied.

[Example] Next, an example of the handrail packing drum of the present invention will be described with reference to the drawings.

FIG. 5 is a partially cutaway cross-sectional view showing an embodiment of the handrail packing drum of the present invention.

In Fig. 5, 6 is the body, 7 is the collar, 8, 8
9 is a mounting jig whose cross section in the circumferential direction is approximately wedge-shaped so that the folded portion of the handrail can be hooked onto the circumferential surface of the body portion 6, and 9 is a pair of mounting jigs 8, 8. A substantially U-shaped handrail storage groove defined by 10 is a mounting jig 8 on the side around which the folded part at the beginning of winding of the endless handrail is wound.
It is a protrusion provided on the side wall of.

As is clear from FIG. 5, the pair of mounting jigs 8, 8 have the greatest thickness at the surface walls facing each other on the circumferential surface of the body 6, and are formed in an arc shape between them. Roughly U-shaped handrail storage groove 9
, and the thickness is gradually reduced from the facing wall to the other end edge side to form an inclined surface extending in the tangential direction of the body 6.

FIG. 6 is an enlarged perspective explanatory view of the surface of the body 6 shown in FIG. 5, and shows a pair of mounting jigs 8,
8 is provided, and this pair of mounting jigs 8, 8
The substantially U-shaped handrail storage groove 9 defined by the groove 9 is deepest at the center of the groove, and has a shallow and wide tapered shape at both ends.

In Fig. 6, the radius R of the mounting jig 8 on the side that wraps the folded part at the beginning of winding of the endless handrail is the bending radius when setting it on an escalator, auto line, etc. in order to prevent kink and deformation of the handrail. It is the same or larger than , but generally it is around 300mm.

FIG. 7 shows a substantially U-shaped handrail storage groove 9 defined on the circumferential surface of the trunk 6 in FIG. FIG. 2 is an enlarged cross-sectional explanatory view showing a state in which the endless handrail 4 is wrapped around the protrusion 10 . By making this protrusion 10 similar in shape to the inner hollow groove of the substantially C-shaped endless handrail 4, it is possible to securely fix the folded portion of the endless handrail 4 at the beginning of winding without deforming it. .

In the present invention, instead of the projection 10, for example, a shade 13 as shown in FIG. 8a, an oblique side wall 14 as shown in FIG. 8b, or a cover 15 as shown in FIG. 8c may be attached. In addition, Fig. 8c is 2
A separator 16 is provided so that the endless handrails 4, 4 of books can be wrapped and packed.

Next, a method for packing the endless handrail 4 will be described using an embodiment of the handrail packing drum of the present invention.

First, as shown in FIG. 7, the folded portion of the endless handrail 4 is erected in the substantially U-shaped handrail storage groove 9 of the handrail packing drum 6 so that the cross section is C-shaped, and the protrusion 10 The endless handrail 4 is housed in such a way that the hollow groove part of the endless handrail 4 fits therein. Then, by rotating the handrail packing drum 6 in the wrapping direction, the endless handrail 4 after the folded portion is wrapped and packed. In this case, while the handrail packing drum 6 is rotating, the folded part of the endless handrail 4 is completely stored in the approximately U-shaped handrail storage groove 9, so that the folded part and subsequent parts are overlapped on the upper layer. Pressure deformation of the protruding portion does not occur even if Furthermore, in this case, since the hollow groove of the endless handrail 4 is housed in the protrusion 10 so as to fit therein, there is no fear that the endless handrail 4 will fall off.

In addition, in the present invention, the mounting jig 8 is thickest at the facing wall and has an arcuate peripheral edge to define a substantially U-shaped handrail storage groove between them. Both of them form an inclined surface extending in the tangential direction of the body by gradually decreasing the thickness from the facing wall toward the other end edge, so that the endless handrail 4 after the folded part is It is possible to wrap and pack the long endless handrail 4 from a standing state with a C-shaped cross section to a gradually lying state, and as a result, even if the long endless handrail 4 is rolled up in layers, it will not be compressed or bent. It can be wrapped and packed.

When the end of the winding of the endless handrail 4 is reached, although not shown in the figure, a filling material is inserted into the hollow groove of the end of the winding of the endless handrail 4 to prevent deformation, and the entire outer periphery is covered with cushioning material, etc. The drum 5 of the endless handrail 4 is fixed by taping the taped part to the flange 7 of the drum 5.
Wrapping and packing is completed.

[Effect of the invention] The handrail packing drum of this invention can wrap and pack a long endless handrail extremely smoothly without deforming it, and as a result, an elegant and durable endless handrail can be installed in a short period of time. It is possible and industrially useful.
