Abstract

PURPOSE:To automate the removal of dust by installing a vertically movable edge surface dust removing brush which vertically moves along the edge surface of a product for a suspending arm for a cylindrical product and a turning dust removing brush which turns along the product, having the axis center of the product nearly as turning center. CONSTITUTION:When a coil product 1 is transported, it is suspended nearly horizontally for the axis center by a suspending arm 2, and cleaning is carried out by attaching an edge surface dust removing brush consisting of a vertically movable edge surface dust removing brush 4 and a turning dust removing brush 5 which are installed on the suspending arm 2, on the edge surface of a cylindrical product. Though the turning dust removing brush 5 turns along the product, having the axis center of the coil product 1 nearly as turning center, the part which can not be dust-removed in turn because of the existence of the suspending arm 2 is dust-removed in the vertical movement by the revolution of the vertically movable edge surface dust removing brush 4. Accordingly, the coil product 1 can be cleaned automatically, without leaving the uncleaned part.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a packaged cylinder or cylindrical article (a cold-rolled coil (a rolled-up cold-rolled steel strip, hereinafter simply referred to as a coil)).
This invention relates to a device for cleaning the end surface of a cylindrical object (hereinafter abbreviated as cylindrical object).

[Conventional technology]

Taking coils as an example before shipping, they are generally sorted by user, loft, delivery date, etc. and stored temporarily in a warehouse, and are then prepared for transportation (arranging between vehicles, shipping, etc.) and adjusting shipping. After this, the products are transported from the shipping warehouse to the shipping yard using coil trolleys or the like, and then loaded onto vehicles using overhead cranes or shipped by ship. In the above-mentioned temporary coil transportation, dust scattered inside and outside the factory adheres to the outer periphery and end face of the coil while it is temporarily stored in the warehouse, reducing the product value and causing inconvenience to the user. There were problems such as the accumulated dust sometimes scattering and causing secondary contamination. In particular, dust adheres to the same area on the end face, but since the end face of the wrapping paper is folded, dust tends to accumulate in specific folds, and it is necessary to knock it out. , had become a problem.

[Problem to be solved by the invention]

In order to prevent the above-mentioned situation, before shipping, a worker manually wipes off the end face of the coil with a brush, such as a brush, etc., to remove dust. In order to prevent this, the coils were covered with a specially provided dustproof cover, such as a vinyl cover, to prevent adhesion, but the coils had various problems before being shipped. For example, in the case of a coil cover, the coil label recording the coil specifications cannot be seen, and there are safety measures when installing the coil cover, loss of waiting time, etc. Also,
Wiping with a brush has problems such as manual removal by one worker, which obstructs automation before shipping. Furthermore, it has traditionally been extremely difficult to clean the outer periphery and end faces due to changes in the outer diameter of the coil, changes in the coil width, etc., and therefore no equipment has been installed to clean the outer periphery and end faces. Ta. Therefore, the above-mentioned measures had to be taken manually by the operator. In other words, there have been many problems with dust removal in the past, no technical measures have been taken, and each department has been forced to take measures. The present invention was made in view of the above circumstances, and is intended to effectively remove dust adhering to the end face of a cylindrical packaged product (hereinafter abbreviated as cylindrical product) such as a coil. It is an object of the present invention to provide a dust removal device that can eliminate the manual work involved in cleaning and also enable automation of equipment.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention has decided that when transferring a cylindrical product, the cylindrical product is lifted with its axis substantially horizontal, and the end face dust removal brush provided on the hanging tool is brought into contact with the end face of the cylindrical product to clean it. It is. As a device for this purpose, a vertically movable end face dust removal brush (4) that moves up and down along the end face of the product is attached to the hanging arm (2) of the cylindrical product (1) provided below from the base (3).
We have developed a structure that includes a rotating dust removal brush (5) that rotates along with the product approximately around the axis of the product.

[Effect]

In the apparatus for removing dust from the end face of a cylindrical object according to the present invention, the cylindrical product (1) can be cleaned by a dust removal brush serving as a cleaning tool while the cylindrical product (1) is lifted up and transferred by the hanging arm. At this time, the upper part of the end face of the cylindrical product (1) is cleaned by vertically movable end face dust removal brush (4) which moves up and down while rotating. The remaining end face of the cylindrical product (1) is covered with a rotating dust removal brush (
5) rotates and removes dust, thereby cleaning the entire end surface of the cylindrical product (1).

[Examples] Examples of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is a diagram showing a dust removal operation. This device has a hanging arm (2) that is installed below the base (3) and has an arm claw at the tip, and a vertically movable end face dust removal brush (4) that moves up and down along the product end face, and a vertically movable end face dust removal brush (4) that moves up and down along the product end face. A rotating dust removal brush (5) is provided. The former vertical movable end face dust removal brush (4) has a brush shaft attached to a horizontally elongated lifting frame (6) via a coupling from a rotary brush drive device (motor) (7) at the end. The elevating frame (6) has an elevating female screw section provided in the vertical direction inside thereof, and is screwed into an elevating screw (8) provided on the side surface of the hanging arm (2). , the lifting screw (8) together with the guide rod on the Wi side,
It is provided in the vertical direction on the side surface of the hanging arm (2), and a lifting drive unit W1 (motor) (9) is provided at the upper end. Therefore, the vertical movable end surface dust removal brush (4) is rotated by the rotary brush drive device (7) and moved up and down by the lifting drive device (9) to remove dust. In an apparatus in which the rotating dust removing brushes (5) rotate along the product with the product axis as the center of rotation, the two rotating dust removing brushes (5) have a two-wheeled rotating structure. One of them is a mechanism that rotates the cylindrical product along the end surface, and there is a rectangular rotating frame (10) that holds the dust removal brush.
The fixed rotating gear (11) is attached rotatably to a rotating shaft (12), which is a shaft. A swing pinion (13) is rotatable on this swing frame (10) by a swing drive device (motor) (14), and meshes with the swing fixed gear (11).
