Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an apparatus for overlapping metal sheets (hereinafter referred to as wrapping) when piling metal seeds that have been sheared on a shearing line.

[Prior art] In high-speed shearing lines for metal strips, such as tin-plated steel strips, when piling tin sheets, the ends of the tin sheets tend to break, so to avoid this, the piling speed is set to 100 m7 minutes or less. must be done. Therefore, in order to enable high-speed shearing, the piling speed is lower than the shearing speed, and the difference in speed is used to reduce the speed of the intermediate conveyor in stages, and finally the tin sheet is wrapped and piled. .

As a conventional tin sheet wrapping apparatus, there is an apparatus shown in FIG. 2 or 3.

The apparatus shown in FIG. 2 has a second belt conveyor 3 whose conveyance speed is slower than that of the first belt conveyor 2 in the conveyance direction of the first belt conveyor 2 that conveys the tin sheet 1 so that the planar arrangement is in series. A driving magnet roll 20 is provided adjacent to the helad pulley 7 of the first belt conveyor. In this device, the first belt conveyor 2
The tinplate sheet 1 transported by the magnet roll 2
This structure is such that the sheet is attached to a sheet of paper and temporarily held there, and then dropped onto a tin sheet on the second belt conveyor 3 that is being conveyed in advance, wrapped, and then piled by a piler 21.

Further, in the apparatus shown in FIG. 3, the second belt conveyor 3 is arranged horizontally, and the first belt conveyor 2 is arranged inclined so that the head pulley 7 corresponds to the tail pulley 6 of the second belt conveyor 3. A presser roll 22 is provided at the rear of the second belt conveyor 3. In this device, the tin sheet 1 conveyed by the first belt conveyor 2 is slid onto the second conveyor 3, and the press roll 22
At the same time as stopping the receiver, it is bitten by the presser roll 22,
It is wrapped with the tin sheet that is being conveyed in advance.

[Problems to be Solved by the Invention] However, conventional metal sheet wrapping devices have various problems. In the apparatus shown in FIG. 2, the metal sheet conveyed from the first belt conveyor is temporarily held by the magnetic force of the magnet roll and transferred to the second belt conveyor. Therefore, it cannot be applied to non-magnetic metal sheets such as aluminum. Further, when the metal sheet is transferred from the first belt conveyor to the second belt conveyor, the sheet may break due to a large head difference.

In the device shown in Figure 3, the metal sheet is slid from the first belt conveyor to the second belt conveyor, and is then bitten by the presser roll while maintaining its angle, so if the tip breaks, I have a problem to say. Particularly in the case of irregularly shaped metal sheets such as scroll sheets whose ends are cut out, the degree of folding of the ends is large.

The present invention solves the problems of the prior art, and aims to provide a metal sheet wrapping device that can be applied to non-magnetic metal sheets and irregularly shaped metal sheets.

[Means for Solving the Problems] The problem is that the second belt conveyor is located at a lower position than the first belt conveyor, the second belt conveyor is located above the tail pulley of the second belt conveyor, and the first belt conveyor is located at a lower position than the first belt conveyor. The present invention is solved by providing a guide plate having a conveyance auxiliary roller positioned from the end of the head pulley of one belt conveyor to cover the tail pulley of a second belt conveyor.

[Operation] Transfer of the metal sheet from the first belt conveyor to the second belt conveyor is performed by a guide plate. Since this guide plate is equipped with a conveyance auxiliary roller, the metal sheet can be conveyed and transferred without being subjected to impact by the rotating action of this conveyance auxiliary roller.

[Embodiments of the Invention] Hereinafter, embodiments of the present invention will be described based on the drawings. 1st
The drawings are views showing an embodiment of the present invention, and in Fig. 1 showing a tin sheet wrapping device, (a) is a front view, and +bl is a plan view. In this embodiment, a second belt conveyor 3 whose conveyance speed is slower than that of the first belt conveyor 2 is arranged in series in plan view in the conveyance direction of the first belt conveyor 2 that conveys the tin sheet 1 which is a metal sheet. The second belt conveyor 3 is arranged at a lower position than the first belt conveyor 2. A guide plate 5 having conveyance auxiliary rollers 4 is arranged between the first belt conveyor 2 and the second belt conveyor 3. This guide plate 4
is located above the tail pulley 6 of the second belt conveyor 3 in the height direction, and covers the tail pulley 6 of the second belt conveyor from the end of the herad pulley 7 of the first belt conveyor 2. It is located in The guide plate 5 has a shape in which the front and rear ends in the conveyance direction are bent downward, and the conveyance auxiliary rollers 4 are idle rollers that slide on the shaft 8, and a plurality of conveyance auxiliary rollers 4 are arranged in the width direction of the guide plate 5.
The upper part thereof is made to protrude from the upper surface of the guide plate 5. The guide plate 5 is arranged between the blade pulley 7 of the first belt conveyor and the tail pulley 6 of the second belt conveyor, and the preferable positional relationship is that the center 9 of the conveyance auxiliary roller 4 is Align it with the center 10 of the tail pulley 6 of the second belt conveyor, or
Alternatively, the center 9 of the conveyance auxiliary roller 4 is positioned forward of the center 10 of the tail pulley 6 of the second conveyor in the conveyance direction. The upper surface of the guide plate 5 should be at approximately the same height as the upper surface of the first belt conveyor 2, and the rear end of the guide plate 5 should be positioned slightly behind the tip of the helad pulley 7 of the first belt conveyor. good.

This guide plate 5 can change its height and angle. This is done by an adjustment mechanism (not shown) driven by electric power, hydraulic pressure, etc., which moves vertically to change the height, or adjusts the upper surface of the guide plate 5 with respect to the conveyance direction of the tin sheet 1. The structure is mainly designed to allow for uphill slopes. By operating this guide plate 5, the impact when the tin sheet 1 falls onto the second belt conveyor 3 can be alleviated, and the bending of the tip and scratches can be eliminated. In addition, the conveyance auxiliary roller 4
The number of plates to be arranged is not limited to the number shown in FIG. Therefore, if the width of the tin sheet 1 is narrow, a single cylindrical roller may be used. Further, it is even better if the conveyance auxiliary rollers 4 are arranged in multiple rows.

A pressing roller 11 is provided above the helad pulley 7 of the first belt conveyor. This pressing roller 11 is fixed to a shaft 12, and compression springs are attached to bearings 13 at both ends of this shaft 12, so that the pressing roller 11 comes into pressure contact with the covered sheet 1 while being rotated. There is. The holding roller 11 has a structure that allows the arrangement to be changed in the width direction of the first belt conveyor 2.

This pressing roller 11 is provided to prevent the tin sheet 1 from meandering during transfer, and is designed to place the tin sheet 1 on the guide route 5 without causing any deviation in the transport direction. Further, the arrangement of the pressing rollers 11 is changed when changing the board width or depending on the arrangement of the irregularly shaped surfaces of the irregularly shaped sheet.

In the wrapping device configured in this way, the tin sheet 1 conveyed by the first belt conveyor 2 moves while being pressed by the pressing roller 11,
Get on the guide plate 5. Then, the tin sheet 1 is further moved by inertia, falls onto the second belt conveyor 3, and wraps with the tin sheet that was previously conveyed. At this time, the tin sheet 1 is smoothly conveyed by the rotating action of the conveyance auxiliary roller 4, and the impact when it falls onto the second belt conveyor 3 is alleviated. Therefore, the tip of the tin sheet 1 will not be bent. Moreover, since the conveyance auxiliary roller 4 is projected from the upper surface of the guide plate 5, it also has the effect of preventing the occurrence of scratches on the tin sheet 1 due to sliding friction with the guide plate 5.

In the above embodiments, only the case of wrapping a tin sheet has been described, but the application of the present invention is not limited to a tin sheet, but can be applied to any other metal sheet.

[Effects of the Invention] As explained above, if the apparatus of the present invention is used, the apparatus is equipped with a guide plate having conveyance auxiliary rollers in order to transfer the metal sheet from the first belt conveyor to the second belt conveyor. As a result, the metal sheet is transported and transferred without being subjected to impact.
Metal sheets can be wrapped without damaging the tip. Therefore, it is also possible to increase the piling speed. Furthermore, since the guide plate does not apply magnetic force, it can also be used for wrapping non-magnetic metal sheets.
