Description

  The present invention relates to a stem used for conveying a wire coil and the like.

  In the step of subjecting a wire rod or steel wire for wire drawing (hereinafter simply abbreviated as a wire rod) to pickling and lubrication, in general, an unbundled wire coil is conveyed by a C hook or the like while being pickled. Immerse in fluid and lubricant. Then, the wire coil after the pickling / lubricating treatment is transported to the next process using an integrated device called a stem (see, for example, Patent Document 1).

  FIG. 1 is a diagram illustrating an example of a conventional stem. As shown in FIG. 1, the conventional stem 100 includes a cylindrical main body 101, a suspension ring 102 fixed to the main body 101, and a bottom plate 103 fixed to the lower end of the main body 101. Four reinforcing members 104 are provided on the upper surface of the bottom plate 103. A slit 101a is formed in the main body 101 so as to extend in the vertical direction. The suspension ring 102 is provided to hook a hook or the like when the stem 100 is conveyed by a ram lift or the like.

  2-7 is a figure for demonstrating an example of the usage method of said stem 100. FIG. As shown in FIGS. 2 to 7, when transferring the wire coil 200 after the pickling / lubricating treatment to the stem 100, a C hook 201, a coil compression carriage 202 and a direction change carriage 203 are used. The coil compression carriage 202 is provided with a coil compression plate 202a. The direction change cart 203 has a main body 204 and a stem holding part 205. The stem holding portion 205 is provided on the main body portion 204 so as to be rotatable by 90 °.

  As shown in FIG. 2, the wire coil 200 after the pickling / lubricating treatment is first transported to a predetermined position by a C hook 201. In addition, the stem 100 is horizontally held by the stem holding portion 205 of the direction changing carriage 203 so that the slit 101a is positioned above. In this state, as shown in FIG. 3, the direction change carriage 203 moves so that the tip of the C hook 201 enters the slit 101 a of the stem 100. Next, as shown in FIG. 4, the coil compression carriage 202 moves to the direction changing carriage 203 side, and the wire coil 200 is pushed in by the coil compression plate 202a. Thereby, it can prevent that the edge part of the wire rod coil 200 in an unbound state collapses from the stem 100.

  Next, as shown in FIG. 5, the coil compression carriage 202 moves to the original position, and the C hook 201 descends. As a result, the wire coil 200 is transferred from the C hook 201 to the stem 100. Finally, as shown in FIGS. 6 and 7, the direction changing carriage 203 moves to the original position, and the stem holding portion 205 rotates 90 °. Thereby, the central axes of the stem 100 and the wire rod coil 200 are oriented in the vertical direction, and the wire rod coil 200 is held. The wire coil 200 having the central axis held in the vertical direction is conveyed to the next process (for example, a wire drawing process) by a ram lift or the like.

  By the way, the wire coil 200 after the pickling / lubricating treatment may be temporarily stored in a state of being held by the stem 100 before being transported to the next process. FIG. 8 is a diagram illustrating a storage state of the stem 100 (wire coil 200). As shown in FIG. 8, when storing a plurality of stems 100, the plurality of stems 100 must be arranged side by side at the storage location. Therefore, when a sufficiently large storage location cannot be secured, a large number of wire coils 200 cannot be stored. Similarly, when storing the stem 100 which is not used, a wide storage place is required.

  The present invention has been made in view of the above problems, and it is an object of the present invention to provide a stem that can save the storage space.

  The gist of the present invention is as follows.

The stem according to the present invention is a stem used when delivering a wire coil, and is formed on a cylindrical small diameter portion having a substantially uniform outer diameter formed on the upper end side and a substantially uniform outer diameter formed on the lower end side. and the body portion that have a large diameter portion cylindrical such, provided at the lower end of the body portion, and a larger bottom plate than the large-diameter portion in the radial direction of the body portion, the large diameter portion The inner plate has an internal space into which the small-diameter portion of another stem can be inserted, and the bottom plate has a hole that communicates with the internal space of the large-diameter portion and through which the small-diameter portion of another stem can be inserted. A slit may be formed in the main body portion so as to extend in the vertical direction.

  The large diameter portion of the stem has an internal space into which the small diameter portion of another stem having the same configuration can be inserted. The bottom plate has a hole that communicates with the internal space of the large-diameter portion and allows the small-diameter portion of another stem to be inserted. Therefore, two stems can be stacked by inserting the small diameter part of one stem into the large diameter part of another stem through the hole of the bottom plate. Thereby, a plurality of stems can be efficiently stored.

  When two stems holding the wire coil are stacked, the upper stem can be sufficiently stabilized by placing the bottom plate of the upper stem on the wire coil held by the lower stem. .

A recess may be formed on the outer surface of the small diameter portion. In this case, even when the main body is held in the horizontal direction, the wire coil is locked in the recess, so that the end of the unbound wire coil can be prevented from falling from the upper end of the main body. it can. In the case where a slit is formed in the main body portion so as to extend in the vertical direction, it is preferable that the concave portion is formed so as to sandwich the slit.

  The stem may further include a suspension ring provided at the upper end portion of the small diameter portion. In this case, since a hook such as a ram lift can be hooked on the suspension ring, the stem can be easily transported.

  According to the present invention, the space for storing the stem can be saved.

  As shown in FIG. 11, the stem 10 holding the wire rod coil 200 is conveyed by the ram lift 20. Here, in the present embodiment, the inner diameter of the large diameter portion 11b is larger than the outer diameter of the small diameter portion 11a, and the hole 13a having a diameter larger than the outer diameter of the small diameter portion 11a in the bottom plate 13 (see FIG. 10). ) Is formed. Accordingly, as shown in FIG. 11, the other stem 10 is transported above the stem 10 on the ground by the ram lift 20, and the small-diameter portion 11 a of the stem 10 on the ground is inserted into the large-diameter portion 11 b of the upper stem 10. By lowering the upper stem 10 as described above, another stem 10 can be stacked on the stem 10 on the ground.

  In the example of FIG. 11, the bottom plate 13 of the upper stem 10 is placed on the wire coil 200 of the stem 10 on the ground. In this case, since the contact area between the wire coil 200 and the bottom plate 13 is sufficiently large, the two stems 10 can be stably stacked. Therefore, it is preferable to determine the dimension of each part of the stem 10 according to the dimension of the wire coil 200 to be processed. Specifically, as described above, it is preferable to determine the dimensions of each part of the stem 10 so that the wire coil 200 and the bottom plate 13 are in contact with each other.
