It is possible.

  FIG. 1 is a diagram illustrating a configuration of a conveyance direction changing device 10 for a cable drum 20 according to an embodiment of the present invention. FIG. 2 is a view of the conveyance direction changing device 10 of the cable drum 20 shown in FIG. 1 as viewed from the AA direction. FIG. 3 is a cross-sectional view taken along line BB of the conveyance direction changing device 10 for the cable drum 20 shown in FIG.

  As shown in FIGS. 1 to 3, the conveyance direction changing device 10 for the cable drum 20 mainly includes a frame body portion 1, an elevating guide 2, a rotary table 3, a main roller 4, an end roller 5, and a side. And a roller 6. The material of each component and the strength of the structure are selected and configured so as to sufficiently cope with the load and impact from the heavy cable drum.

  The frame part 1 is a frame member that forms the main part of the cable drum transport direction changing device, and is a structure that can withstand the weight when the outer peripheral surface of one flange part of the cable drum is placed. The frame part 1 is composed of a flat plate 1a and two side plates 1b that are erected in the longitudinal direction of the flat plate 1a.

  The frame body portion 1 has a form similar to a side groove, and the cross section of the frame body portion 1 has a substantially U-shape opened upward. Since the flange portion of the cable drum is positioned in the U-shaped portion, the width dimension of the U-shaped portion is, for example, about three times the thickness dimension of the flange portion.

  The bottom of the frame body 1 is supported by a turntable 3 described later.

  The raising / lowering guide 2 is arrange | positioned at the outer edge of the substantially U-shaped one end surface side of the frame part 1, and makes it easy to roll the cable drum 20 and to mount on the cable drum conveyance direction change apparatus 10 which concerns on this embodiment. It is.

  For example, the elevating guide 2 is preferably in the form of a triangular prism whose bottom surface is a right triangle, and in use, the elevating guide 2 is arranged in a horizontally lying shape so as to be in contact with the outer edge on the one end face side of the frame body portion 1. .

  The surface of the inclined surface (slope) of the elevating guide 2 is preferably subjected to anti-slip processing. For example, a substantially horizontal groove is formed along the inclined surface (slope) in order to prevent the edge of the cable drum 20 from slipping off.

  It is preferable that the height of the top of the inclined surface of the elevating guide 2 is approximately the same as the height at which the later-described main roller 4 is disposed in the frame body portion 1.

  Note that the end surface of the elevating guide 2 and the frame body portion 1 are maintained as necessary so that a fixing force between the end surface of the elevating guide 2 and the one end surface side of the frame body portion 1 is maintained to prevent displacement. It is also preferable to provide a detachable locking portion (not shown) by fitting the concave and convex portions between the end faces.

  The elevating guide 2 can be separated from the frame 1 so as not to hinder the direction change when not in use or after the cable drum 20 is placed on the transport direction changing device.

  The turntable 3 is a plate member for supporting the frame body portion 1 from the bottom, and is rotatable in the horizontal direction.

  The rotary table 3 includes, for example, a table rotary body (not shown) having a table surface (not shown) that holds the bottom of the frame body portion 1 at a central portion, and the table rotary body rotates via a bearing (not shown). It can be configured with a body (not shown) that can be supported.

  The table rotating body is configured to be rotatable about a rotation axis by transmitting a rotating force by applying a force to the frame 1 of the operator.

  The body is disposed outward so as to cover the outer periphery of the table rotating body. It is preferable that the body is provided with a sealing material (not shown) serving as an oil seal between the table rotating body. This is because the lip portion of the sealing material is in contact with the outer peripheral surface of the table rotating body and is in sliding contact during rotation, thereby preventing entry of foreign matter from the outside.

  The bottom surface of the rotary table 3 is placed on the ground or floor surface.

  The main roller 4 is rotatably attached to the inside of the frame body portion 1, that is, between the two side plates 1b, and supports the flange portion of the cable drum 20 mounted thereon. The main roller 4 can be formed as a cylindrical body or a columnar body having both ends attached to the side plate 1b. For example, the main roller 4 is preferably supported rotatably via a bearing (not shown).

  In order to receive and support the weight of the cable drum 20, the main roller 4 is preferably composed of a plurality of rollers arranged at a predetermined interval in the longitudinal direction of the frame body portion 1. For example, the main roller 4 can be composed of three.

  In parallel with the plurality of main rollers 4, an end roller 5 is attached so as to be rotatable inside the frame portion 1, that is, between the two side plates 1b. The end roller 5 is disposed on the outermost side of the frame body portion 1, that is, on the side opposite to the side where the lifting guide 2 is disposed. The end roller 5 can also be formed as a cylindrical body or a columnar body having both ends attached to the side plate 1b.

  The end roller 5 preferably has an outer diameter larger than that of the main roller 4 installed in the middle. For example, the diameter is about 1.5 times larger. In this way, by enlarging the diameter of the end roller 5 installed on the outermost side, when the flange portion of the cable drum 20 is placed, the cable drum 20 with a splash is excessively passed, and the cable drum carrying direction is changed. The structure does not drop off from the device 10.

  The side roller 6 is attached so as to be rotatable between the flat plate 1 a and the side plate 1 b of the frame body portion 1. The side roller 6 prevents the rotation of the flange portion of the cable drum 20 from being hindered even when the cable drum 20 riding on the main roller 4 is displaced in the short direction of the frame body portion 1. The side roller 6 can be formed as a cylindrical body or a cylindrical body.
