Description

[Detailed Description of the Invention] The present invention relates to a device for smoothly feeding out pipes from a bundle of plastic pipes such as cross-linked polyolefin pipes, particularly a bundle of large-sized pipes having an inner diameter of 50 mm or more. Traditionally, large plastic pipes have been stored and transported wrapped around large drums, but this method requires expensive large drums, and the heavy weight of the drums results in high transportation costs. Furthermore, due to their high weight and large volume, they are difficult to transport to mountainous areas. For this reason, the inventors of the present invention have developed a pipe dispensing device shown in FIGS. 1 and 2, which is capable of disassembling and assembling pipes from a bundle of large-sized pipes. FIG. 2 is a top view of FIG. 1, and the base 1 includes a base 11, a wedge 12 fixed under the base 11 (this fixes the base 11 to the ground), and a wedge 12 fixed on the base 11. It consists of a rotating support 13, a thrust and a bearing 14 fixed to the rotating support 13. The pipe bundle support 2 includes an arm support 21, four arms 22 that are supported by fitting into the support 21 as shown in FIG. 2, and an inner support 2 erected on the arms 22.
31 and an outer support 232 as a pair
It consists of a strut 23 for preventing the pipe bundle from separating from the pipe bundle support, and a radial bearing 24 fixed to the arm support 21. By rotating the pipe bundle support 2 of the above device, pipes can be fed out from the pipe bundle P , but at this time, the pipe portions unraveled from the pipe bundle P are placed at a position higher than the tips of the inner and outer supports 231, 232. It is necessary to bring it up. The present invention proposes an improved pipe dispensing device that is capable of dispensing pipes without lifting the pipes, and prevents the separation of the pipe bundle from the pipe bundle support, as indicated in the claims of the utility model registration. The outer support of the pair of inner and outer supports is inclined toward the outside of the pipe bundle support. Since the prerequisites of the present invention are the same as those illustrated in FIGS. 1 and 2, only the essential parts of the present invention are shown in FIG. The present invention will be explained below with reference to FIGS. 1 to 3. In Fig. 3, 22 is an arm, and 23 ' is an inner support 231 and an outer support 232' inserted into holes provided in the arm 22.
It consists of. P is a pipe bundle. As shown, the outer struts 232' are sloped outwardly of the arms 22 so that the outer struts 232'
2), the pipe section P ₁ indicated by the dotted line climbs up along the inclined outer support 232' as shown by the arrow and reaches the position indicated at P ₁ ', and is unwound. . The angle of inclination θ of the outer strut 232' has an optimum value depending on the size and height of the pipe bundle P , the size and hardness of each pipe in the pipe bundle, but it can be within the range of about 20 to 60 degrees. Generally effective. As shown in FIG. 4, the outer support 232' may have a multi-step slope (FIG. 4a), or may have a curved shape such as an arc as a whole (FIG. 4b). ). Although a four-arm type is shown in FIGS. 1 and 2, a three-arm type may be used, and instead of the arm type, the pipe support may be table-shaped. However, in that case, even if it is disassembled, it will be bulky, so it is convenient for transportation to split it in half. On the other hand, if there are two pillars 23 ' located at the target positions around the center of rotation, it is possible to prevent the pipe bundle from wobbling, moving, or coming off during the pipe delivery operation, but in order to secure it more securely, it is necessary to have three or more pillars 23'. It is desirable to do so. Note that the inner support 231 and the outer support 232' that make up the support 23 ' do not necessarily have to be installed on the same line in the radial direction from the center of rotation; The strut groups may be installed on the same circumference within each group at appropriate intervals, preferably at equal intervals. Although not shown in FIGS. 1 to 4, there are a number of pillars 2 provided at regular intervals on the surface of each arm.
31, 232' are provided, and the installation positions of the inner support 231 and the outer support 232' can be freely changed according to the bundle width of the pipe bundle P. In the present invention, since the outer support 232' is inclined outward, a space is created between the support and the pipe bundle P as shown in FIG. The pipe bundle P may collapse and fall. In many cases, this falling-off phenomenon itself does not interfere with the unwinding operation, but if falling off itself becomes a problem, it is necessary to prevent this falling-off by applying several layers of partial binding to the pipe bundle. I can do it.
