Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer conveyor installed in a steel sheet forming line.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Patent Publication No. 2-6626, for example, an uncoiler for holding a relatively wide steel original plate wound in a coil shape and rewinding it from the outer periphery, and a rewinding method. Adhesive applicator that applies adhesive to the cured original plate, heating machine that heats this adhesive, and heat insulating material attaching machine that attaches the heat insulating material to the original plate with the melted adhesive sandwiched. There is a steel plate forming line in which a feeding device group and a forming device group that performs various types of forming such as corrugations on a raw plate supplied from the feeding device group are arranged in series.

In this type of steel sheet forming line, an endless belt having a large surface friction coefficient is stretched over a plurality of driving rollers, and an original sheet fed from the feeding device group side is an upper belt of the endless belt. A transfer conveyer is installed which is placed on the surface and is fed to the molding apparatus group side.

By the way, the layout of the steel sheet forming line as described above is generally determined by the lengths of the feeding device group and the forming device group, but when the space in the factory is limited, the inclination of the transfer conveyor is inclined. In many cases, the line length is reduced by increasing the degree of.

[0005]

However, in the conventional transfer conveyor installed as described above, the frictional resistance of the original plate to the upper belt surface of the transfer conveyor decreases as the degree of inclination increases. For this reason, the original plate becomes slippery with respect to the upper belt surface, which prevents the original plate from being smoothly fed to the molding apparatus group side. As a result, there is a problem that the original plate is clogged just before the molding apparatus group side. Also, this "clog"
In addition to the degree of inclination of the transfer conveyor, the frequency of occurrence varied depending on the difference in the size of the original plate and the material of the heat insulating material.

Therefore, when a "clogging" occurs,
The reality is that a monitoring worker who pushes the original plate toward the molding device group must be placed immediately before the molding device group side.

The present invention was created in consideration of the above circumstances, and it is an object of the present invention to provide a transfer conveyor for a steel sheet forming line which does not require a monitoring worker to be arranged immediately before the forming apparatus group side. It is intended.

[0008]

In order to achieve the above-mentioned object, the present invention provides an original plate in which an endless belt is stretched over a plurality of driving rollers and is fed from a feeding device group side of a steel plate forming line, In the transfer conveyor of the steel plate forming line that is sent to the forming device group side of the steel plate forming line on the upper belt surface of the endless belt, the original plate is sandwiched in cooperation with at least one of the drive rollers, and the upper belt surface is formed. A self-weighted press roller for increasing the frictional resistance of the original plate against the above, and for preventing the original plate from slipping with respect to the upper belt surface immediately before the forming device group side is provided almost directly above one of the drive rollers. It has a feature.

[0009]

According to the transfer conveyor of the steel sheet forming line according to the present invention, the original sheet is sandwiched in cooperation with the driving roller to increase the frictional resistance of the original sheet to the upper belt surface of the endless belt, and the upper side immediately before the forming apparatus group side. Since a self-weighted press roller that prevents the original plate from sliding on the belt surface is installed almost directly above one of the drive rollers, it is affected by the degree of inclination of the transfer conveyor, the size of the original plate, and the material of the heat insulating material. The original plate can be reliably sent to the forming device group side. Therefore, it is possible to omit arranging a monitoring worker immediately before the molding device group side.
