Abstract

PURPOSE:To improve efficiency of drum winding and delivery operation by a method wherein a drum pushing axle having the height corresponding to the size of the drum diameter is selected optionally and driven, in a wire winding drum supporting device. CONSTITUTION:Either a high or low pushing axle is selected in response to the size of the drum applied. When the high pushing axle is selected, a pushing axle 3A at a higher position on a base block 4 is extended by a hydraulic cylinder 31A up to a supporting position and then a pushing head 5 is set to the extremity end of the axle. In turn, as for the base block 2, a disc 8 is fitted to the extremity end of the pushing axle 6 at a higher position. Replaced gear 23 is fixed to engage with a feeding gear 24, and a feeding driving shaft 9 is rotated, resulting in that a feeding screw cylinder 19 is rotated to move the feeding screw shaft 18, the disc 8 is approached to the pushing head 5 to hold the drum 1. When the pushing axle at a lower position is selected, the pushing head 5 is set to the pushing axle 3B on the base block 4 side, and the disc 8 is set to the pushing axle 7 at the base block 2 side. In this way, it is possible to accommodate rapidly and easily to any variation in size of the drum and efficiency of operation is improved.

Description

[Detailed description of the invention] This invention relates to a drum support device.

Conventionally, a drum support device used for feeding a wire from a drum or winding a wire onto a drum, as shown in FIG.
By pinching and supporting the drum 1 from both sides of its flange plate by the pressing shaft 104 supported coaxially with the pressing shaft 103 on the base 102 arranged opposite to this, and by driving and rotating the pressing shaft 104. It has a structure that rotates the drum 1. In this conventional drum support IT, if the drum 1 has a large diameter, each base 101°102
If there is a risk of collision with the installation ground G, install the raising bases 106 and 107 below the bases IQ1.1G2 and lift these bases upward, or, although not shown, Unit 101.102 -
− − 1 □ ゛ The ground in the middle of the − must be excavated to achieve the same effect, making it virtually impossible to adapt to changes in drum diameter. Takko's invention was made in order to eliminate the above-mentioned problems, and it is a new drum support device that can select two supporting positions, 1.4% and low, depending on the diameter of the drum used. It provides:

Next, an embodiment of the present invention will be described with reference to FIGS. 2 to 4. FIG. 2 is a schematic side view showing the entire drum support device of the present invention. On the base 4 on the left side of the figure, there are two high and low stages ah 2 parallel to each other in a horizontal state. The two extending drum suppression shafts 3A and 3B are each 31 fluid pressure cylinders.

31B so that they can move forward and backward in the axial direction, and a tapered cone-shaped drum suppression head 5 is detachably attached to the tips of the drum suppression shafts 3A and 3B. In the illustrated example, the pressing head 5 is currently mounted on the pressing shaft 3A side.

Also, on the right side of the figure, two drum suppression shafts 6 and 7 (only the higher suppression shaft 6 is visible in the figure) are located at the high and low two levels on the base 2, respectively. It is disposed coaxially and horizontally opposite aA and aB, and a disk 8 equipped with a Taber cone-shaped drum press head 85 is removably attached to the tip of the drum press #+6.1. . In the illustrated example, the disk 8 is now attached to the suppression shaft 6. FIG. 8 is a front view of FIG. 2 when viewed in the direction of the arrow (■), and the drum suppression shaft 7 and drive shaft 9, which are not shown in FIG. 2, are clearly shown in this diagram.

With reference to FIG. 4, which is a cross-sectional view taken along line ff-IV in FIG. Explain the mechanism. The casing 20 has two rotating hollow cylinders 15A in the shape of hollow cylinders.

The two rotating hollow shafts 15A and 15B are rotatably provided at two positions, high and low, so that the shafts 15B extend almost horizontally.
In between, a drive shaft θ is rotatably provided in parallel with these hollow shafts 15A and 15B. Rotationally driven from the source 30 (Fig. 8) to the rotary drive shaft 8 □.

A drive gear 12 is also fixed as a key 11, and these rotations are controlled by meshing with gears 13 and 14 fixed on the rotary hollow carrier 15 and 1.5B respectively. The hollow shafts 15A and 15B are rotationally driven.

The drum suppression shaft 6 at a high position is attached to the rotating hollow shaft 15A, and the drum suppression shaft 7 at a low position is attached to the rotating hollow shaft 15B so that they can slide freely in the axial direction but are prevented from rotating in the circumferential direction. ing.

Hereinafter, regarding one drum suppression shaft 6, the mechanism for moving the drum pressure shaft forward and backward in the axial direction will be explained in detail. The drum suppression shaft 6 is formed to extend in the axial direction on the inner wall surface of the rotary hollow shaft 15A, and this structure prevents the drum suppression shaft 6 from rotating relative to the rotating hollow shaft 15A in the circumferential direction, but allows it to freely slide in the axial direction. has been done.

A similar configuration is also used for the drum suppression shaft 7 located at a lower position. The explanation will be continued below focusing on the drum pressing shaft 6# at the high position, but since this is exactly the same for the drum suppressing shaft 1 at the low position, the explanation about the suppressing shaft 7 will be omitted.

Base 4 of pressing shaft 6. One end of a feed screw shaft 18, which extends coaxially with the rotary hollow shaft 15A, is relatively rotatably engaged with the end opposite to the rotary hollow shaft 15A. This feed screw! [11
18 is screwed into a female thread formed on the inner wall of a hollow cylindrical feed screw cylinder 1B rotatably provided in the casing 20, and thereby moves forward and backward in the axial direction as the feed screw cylinder IB rotates. do. In other words, the suppression shaft 6 is moved forward and backward by the same number in the axial direction.

A feed gear 24 is coaxially fixed to the feed screw 1e. On the other hand, for the suppressing shaft 1 at a lower position, a feed screw cylinder 27 having exactly the same shape is provided corresponding to this feed screw cylinder 19. However, the feed gear 25 coaxially fixed to the feed screw cylinder 2 is different from the feed gear 24.
Please note that even though the gears are the same, the mounting positions in the axial direction are the same. That is, this means that the replacement gear 23 attached to the end of the feed drive shaft 21 by insertion is set to either the feed gear 24 or the feed gear 25Q) corresponding to each replacement position. The gears 24 and 25 are constructed so that they mesh with each other. Instead of inserting the replacement gear 23, the gears 24 and 25 are replaced by switching the clutch.
It may be configured to mesh with either of the two. Further, the feed drive shaft 21 is located coaxially with the drive shaft 9, and is driven by a chain via a fixed drive sprocket 22.

A prismatic recess 61 is formed at the end of the pressing shaft 6 facing the base 4, into which a correspondingly shaped insertion shaft 81 of the disc 8 is inserted. A part of the plate surface of the disk 8 is provided with an engagement protrusion 82 for engaging with the flange plate of the drum 1 to rotate it, and a tapered cone-shaped drum presser is provided at the center of the plate surface. A head 85 is provided. This pressing head 85 is inserted into the end of the shaft hole of the drum 1 and supports the drum 1 under pressure.

The operation of the device shown in the missing number will be explained. First, select either high or low suppression axis depending on the size of the drum you are using. When selecting the higher pressure shaft, move the three pressure shafts at the higher position on the base 4 side to the fluid pressure cylinder 31A as shown in Figure 2.
It is extended to the support position shown in the figure, and the suppression head 5 is attached to the tip thereof.

On the other hand, as for the base 2, as shown in FIG. 4, a corresponding high-position suppression shaft 6 is selected and its distal end striped disk 8 is inserted and mounted. Further, the replacement gear 23 is mounted in the illustrated position, that is, so as to mesh with the feed gear 24, and the feed drive shaft 9 is rotated in this state. Then, the feed screw cylinder 19
rotates to feed the feed screw shaft 18 in the axial direction, and the drum pressing shaft 6 is pushed out toward the drum pressing shaft 5 facing the base 4 side. In this way, if the drive source 30 is started after the shaft hole of the drum is suspended from a crane or a hoist, etc. The rotational force is transmitted via the hollow shaft 15A, the pressing shaft 6, and the disc 8 in this order, and the supported drum is rotationally driven.

Also, when selecting a suppression shaft at a low position due to the size of the drum, select the suppression shaft 3B at a low position on the base 4 side and attach the suppression head 5 to it; Select the suppression shaft 1, attach the disc B to it, replace the replacement gear 23 inside out, mesh with the feed gear 25, and push out the suppression shaft 1 in the same way as in the previous case. good.

According to the present invention, as mentioned above, the drum pressing shaft can be selected and driven at any height depending on the diameter of the drum used, so that the drum size can be varied. This has the effect of being able to respond quickly and easily, which in turn improves the efficiency of drum winding and feeding operations (this has a large effect).
