SUMMARY OF THE INVENTION In the above-mentioned package, the cylindrical plate 1 as the contents is composed of an outer steel plate 3, an inner steel plate 4,
Since it is covered with the end face cap 5 and the reinforcing cap 6, sufficient mechanical packing strength can be obtained. By the way, when the inner peripheral steel plate 4 as an exterior material is inserted into the center of the plate material 1 formed in a cylindrical shape, it is inserted in a state of being formed into a substantially cylindrical shape as shown in FIG. For this reason, the inner peripheral steel plate 4 is formed into a cylindrical shape having a diameter slightly smaller than the inner peripheral diameter of the center hole 1b formed at the center of the plate 1 in advance. Such an inner peripheral steel plate 4 is a steel plate having a thickness dimension of about 1 mm or less, but may have a weight of about 10 kg due to its large area.

In addition, conventionally, since the operation of inserting the inner peripheral steel plate 4 into the center hole 1b of the plate material 1 is manually performed by an operator, there is a demand for automation to improve the working environment. was there. To achieve this automation,
When the inner peripheral steel plate 4 is inserted into the center hole 1b, FIGS.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a front view showing an exterior device as one embodiment,
FIG. 2 is a cross-sectional view taken along the line II-II showing a positioning part attached to the support arm, and FIG. 3 is an enlarged view of a part III in FIG. The illustrated exterior device 10 has the ability to run on the floor F by itself, and includes a carriage 11 having a built-in drive system for traveling, and a support arm 12 provided on the carriage 11. The carriage 11 is provided with a plurality of running wheels 13 on the lower surface, and can run freely on the floor F.

The support arm 12 includes a first arm 14 and
And a second arm 15. First arm 14
Is swingable in a vertical plane via a first joint 16 attached to the carriage 11 so as to be pivotable in a horizontal plane. The second arm 15 is swingable in a vertical plane via a second joint 17 attached to the open end of the first arm 14. The second arm 15 has a cylindrical shape as shown in FIG. 1 or FIG. 2, and a contact member 18 for supporting the inner peripheral steel plate 4 as an exterior material is replaceably inserted into the outer periphery of the second arm 15. Has become.

The contact member 18 has two contact surfaces 18a and 18b formed with different curvatures, each of which is slightly smaller than the inner diameter of the center hole 1b formed in the plate 1. That is, the curvature substantially matches the curvature of the inner peripheral surface of the inner peripheral steel plate 4 formed into a cylindrical shape. As a result, the inner peripheral steel plate 4 is supported by its own weight without sagging in an elliptical shape as shown in FIG. Two contact surfaces 18a, 18b
Are different from each other because the inner peripheral steel plates 4 having different inner diameter values can be supported. When the contact surface 18a having a small curvature is upward as shown in FIG. 2, the inner peripheral steel plate 4 indicated by A having a small inner diameter is supported while maintaining a substantially cylindrical state. When the contact surface 18b having a large curvature faces upward (when the contact member 18 is mounted upside down in FIG. 2), the inner peripheral steel plate 4 indicated by B having a large inner diameter has a substantially cylindrical state. It is supported while maintaining it. In addition, by replacing the contact member 18, it becomes possible to support the inner peripheral steel plate 4 other than the inner diameters indicated by A and B.

In order for the inner peripheral steel plate 4 formed into a cylindrical shape to be supported by the contact surface 18a or 18b while maintaining a substantially cylindrical state, the contact surfaces 18a and 18b and the inner peripheral steel plate 4 are required.
It is necessary to ensure that the contact angle α (the opening angle with respect to the center of the cylindrical shape of the inner peripheral steel plate 4) with respect to the inner peripheral surface is somewhat wide. The angle α varies depending on the thickness of the inner peripheral steel plate 4 and the like, but is considered to be preferably, for example, about 60 degrees to about 90 degrees or more. However, the angle α is not limited to this angle range, and is not limited to this angle range. Needless to say, the above may be adopted.

As shown in FIG. 3, an air cylinder 19 is mounted on the upper surface of the contact member 18 and near the second joint 17. This air cylinder 1
A plate-shaped urging member 20 is attached to the drive shaft 19a of the ninth. As shown in FIG. 2, the biasing member 20 has a through hole 20a having a shape substantially equal to the cross-sectional shape of the contact member 18.
Is formed, and attached with the contact member 18 inserted into the through hole 20a. The above air cylinder 19
When the drive shaft 19a is driven forward and backward, the biasing member 20 is driven in the range shown in FIGS. If one end of the inner peripheral steel plate 4 is within the moving range of the biasing member 20,
The inner peripheral steel plate 4 is pushed out toward the end face of the plate material 1 by the projecting operation of the drive shaft 19 a of the air cylinder 19.

Next, the electric system will be described with reference to FIG. The electrical system of the exterior device 10 includes a control unit 22 mainly configured by a CPU (Central Processing Unit) serving as a control center of the present device, and dimensional data (width) about the cylindrical plate 1 transmitted from a host computer (not shown). A reception processing unit 23 that receives and decodes dimensions, outer diameter values, inner diameter values, and the like, and packing data (whether or not an inner steel plate is inserted), and a RAM (Random) that temporarily stores the decoded received data. Access Memory) and a power supply 25 such as a battery, and the cart 11
A motor driver 26 for driving the running wheel 13 in the forward and reverse directions, which is built in the motor, a motor 27 driven by the motor driver 26 for driving, an arm driving unit 28, and mounted on the contact member 18 And an electromagnetic valve 29 for driving the air cylinder 19.

The arm drive unit 28 includes a support arm turning motor driver 30 which is built in the carriage 11 and drives a motor 31 for turning the first joint 16 in a horizontal plane, and a first joint 16. A first joint motor driver 33 for driving and controlling a motor 32 for driving the first arm 14 in a vertical plane;
And a second joint motor driver 35 for driving and controlling a motor 34 for driving the second arm 15 in a vertical plane.

The operation state of the exterior device having the above structure will be described with reference to FIGS. First, in a step before the step of inserting the inner peripheral steel plate 4 by the present apparatus, the outer peripheral steel plate 3 is wound around the outer peripheral surface of the illustrated plate material 1. Next, the packaging data and dimensional data transmitted from the host computer (not shown)
When received at 0, the received data is decoded via the reception processing unit 23 and written to the storage unit 24. Therefore, the control unit 22 refers to the data written in the storage unit 24 and transfers the drive command to the driver of each unit.

When the inner peripheral steel plate 4 formed in a cylindrical shape is set on, for example, the contact surface 18a on the contact member 18, the carriage 11 moves from the position shown in FIG. At the same time, the contact member 18 is translated in a vertically upward direction. When the bogie 11 is moved to the position shown in (d), the inner peripheral steel plate 4 supported by the contact member 18
When the advancing of the contact member 18 is stopped, the end 4a of the inner peripheral steel plate 4 projects leftward from the end surface 1a of the plate 1 as shown in FIG. It is in a state where it has been done.

In this state, the drive shaft 19a of the air cylinder 19 is driven to protrude. By the driving of the drive shaft 19a, the urging member 20 is moved rightward in the drawing as shown in FIG. And the urging member 20
As a result, the end portion 4a of the inner peripheral steel plate 4 and the end surface 1a of the plate material 1 are pressed so as to match. That is, when the urging member 20 pushes the end 4a of the inner peripheral steel plate 4 and the urging member 20 abuts against the end surface 1a of the plate material 1, the inner peripheral steel plate 4
Is aligned with the end surface 1a of the plate 1. That is, in the present embodiment, the width dimension of the inner peripheral steel plate 4 is substantially equal to the width dimension of the plate material 1, and the inner peripheral steel plates 4 are separated from each other within the center hole 1 b of the plate material 1 by the above-described insertion work. It is mounted in a state where the dimensions match.

In the above-described operation of inserting the inner peripheral steel plate 4, the inner peripheral steel plate 4 is previously formed into a cylindrical shape having an outer diameter slightly smaller than the inner diameter of the center hole 1b of the plate material 1.
In addition, due to the curvature of the surface of the contact surface 18a or 18b of the contact member 18, the inner peripheral steel plate 4 is inserted into the center hole 1b of the plate 1 while maintaining the cylindrical shape. As shown in FIG. 12, it is reliably inserted into the center hole 1b without sagging in an elliptical shape due to its own weight.

After the work of aligning the inner peripheral steel plate 4 shown in FIG. 7, the second arm is lowered slightly, the contact member 18 is separated from the inner peripheral surface of the inner peripheral steel plate 4, and the bogie 11 is moved as shown in FIG. It moves to the left in the drawing, and the contact member 18 is pulled out.
Before the above operation, the outer peripheral steel plate 3 is wound around the outer periphery of the plate material 1 on which the packaging sheet 2 is wound, and the inner peripheral steel plate is inserted into the center hole 1b of the cylindrical plate material 1 by the operation of the support arm. 4 is attached. Thereafter, the end cap 5 shown in FIG.
Is completed, and the package shown in FIG. 8 is completed.

In the case of the exterior device having the above structure, even if the inner peripheral steel plate 4 formed into a cylindrical shape is supported by the above-mentioned abutting member 18, the abutting member 18 and the inner peripheral steel plate 4 Is formed so as to match the curvature of the inner peripheral steel plate 4, so that the formed cylindrical shape is not deformed even by its own weight. Therefore, even if the outer diameter of the inner peripheral steel plate 4 is slightly smaller than the inner peripheral dimension of the insertion portion of the plate material 1 as described in the above embodiment, automation is easily performed. be able to.
Further, since the end of the inner peripheral steel plate 4 inserted by the air cylinder 19 and the urging member 20 is urged to bring the end surface 1a of the plate material 1 into agreement with the end 4a of the inner peripheral steel plate 4,
This also facilitates automation.

As described above, since the present embodiment can be automated, it is possible to eliminate the manual work of inserting the inner peripheral steel plate. Therefore, it is possible to relieve the operator from heavy labor, and to thereby reduce the production cost and the time required for the process.

The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the invention. For example, in the above embodiment, two types of contact surfaces 18a and 18b of the contact member 18 are provided.
A contact surface having a certain curvature may be formed.

In the above operation, the outer peripheral steel plate 3 is wound around the sheet material 1 on which the packaging sheet 2 is wound, and then the inner peripheral steel plate 4 is wound.
Is inserted to match the end 4a with the end face 1a of the plate material. For example, after attaching the end face cap 5 shown in FIG.
The inner peripheral steel plate 4 may be inserted inside the inner peripheral surface 5b of the end cap 5. In this case, the end 4 a of the inner peripheral steel plate 4 is aligned with the surface of the end face cap 5 by the urging member 20 driven by the cylinder 19.
