Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a work processing line device such as press working, and in particular, a work processing line device for positioning a work such as a plate material in the width direction by a side gauge. Regarding

(Prior Art) When sequentially processing a plurality of positions of one workpiece such as bending of a plate material such as box bending, the work processing line has a processing station in the middle of the work processing line, When the workpiece is conveyed on the work processing line, predetermined processing such as bending is sequentially performed on predetermined locations of the workpiece.

In the work machining line as described above, when the workpiece is a plate material or the like, a side gauge (side guide) provided on one side in the width direction of the work machining line is provided with By pressing one side of the workpiece with a pressure member provided on the other side in the width direction, positioning is performed in the direction orthogonal to the transport direction.

(Problems to be Solved by the Invention) Conventionally, generally, the center line of conveyance of a workpiece in a work processing line as described above is arranged in a straight line from the start point to the end point of the work processing line. Therefore, even if the side gauges are provided on the same side in the width direction of the work processing line from the start point to the end point of the work processing line,
Even if this is installed on the side that is reversed when viewed in the width direction of the workpiece machining line with the machining station as the boundary, when the workpiece passes through one machining station and moves to the next section of the workpiece machining line. However, there is a possibility that this may collide with the side gauge.

For this reason, conventionally, each time a workpiece is loaded onto the workpiece processing line, the side gage in the corresponding section is retracted, and the side gauge can be returned to its original position after avoiding interference with the workpiece. It is being appreciated.

The movement of the side gauge as described above is performed by a geared motor with a brake or the like, but since the side gauge must be reciprocated with high precision every time one workpiece is loaded, the brake wear is reduced. It is relatively hard and causes problems with the durability of the brake.

The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a work processing line device that does not require the side gauge to be retracted each time a workpiece is loaded, and has excellent durability and maintainability.

(Means for Solving the Problems) In view of the conventional problems as described above, the present invention provides a first processing station for performing a first processing on a plate-shaped workpiece, and the above-described workpiece. A second machining station for performing a second machining, and a first work table for carrying and positioning the workpiece with respect to the first machining station,
A second work table for carrying and positioning a workpiece to the second processing station;
The first machining station is arranged on the basis of the conveyance center of the work table, the second machining station is arranged on the basis of the conveyance center of the second work table, and the conveyance center of the first work table is arranged. Second
The work center of the work table is deviated by a predetermined amount in the horizontal direction orthogonal to the carrying direction, and
On the second work table, the side gauges for positioning the workpiece in the width direction are arranged on the bias sides and on the opposite sides of each other.

(Operation) According to the present invention, with the above configuration, the side gauge is brought into contact with the first work table to position the workpiece in the width direction, and the workpiece is conveyed to the first machining station to perform the first machining. After carrying out, when the work material is conveyed onto the second work table, the conveyance centers of the first and second work tables are deviated, and the side gauge in the second work table is Since it is on the side opposite to the side gauge in the work table, the work piece does not come into contact with the side gauge in the second work table.

Embodiment An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows an embodiment in which a work processing line device according to the present invention is applied to a bending processing line.

In the figure, reference numerals 1 and 3 respectively denote work tables constituting a work processing line device, and a bending machine 5 is provided between the work tables 1 and 3. The bending machine 5 is a first and second processing station for processing the workpiece W, and includes two bending dies 7 in the work transfer direction.
9 has a bending die 7 for bending the front edge of the workpiece W, and the bending die 9 for bending the rear edge of the workpiece W. It has become.

The work tables 1 and 3 each have a plurality of rollers 11 and 13, and by rotating these rollers 11 and 13, the workpiece is conveyed from left to right as viewed in FIG. It has become so.

On one side (upper side in FIG. 1) of the work table 1 in the width direction, a side gauge 17 including a plurality of roller members 15 arranged upright between the rollers 11 is provided. Further, on the other side of the work table 1 in the width direction, a pressure member 21 composed of a plurality of pressure rollers 19 provided upright between the rollers 11 is provided.

The pressure member 21 is guided by a guide rail 23 so as to be capable of reciprocating in the width direction of the work transfer line, and is reciprocating by a driving means (not shown).

On the other side (lower side in FIG. 1) of the work table 3 in the width direction of the work transfer direction, a side gauge 27 composed of a plurality of roller members 25 arranged upright between the rollers 13.
Further, a pressure member 31 including a plurality of pressure rollers 29 provided upright between the rollers 13 is disposed on one side in the width direction of the work table 3. The pressure member 31 is guided by the guide rails 33 and can reciprocate in the width direction of the work transfer line, and can be reciprocated by drive means (not shown).

Work table 1 side gauge 17 and work table 3
The side gauge 27, the pressure member 21 of the work table 1 and the pressure member 31 of the work table 3 are disposed on opposite sides of the bending machine 5 in the width direction.

That is, the side gauge 17 is arranged on the upper side in the figure, whereas the side gauge 27 is arranged on the lower side in the figure, and the pressure member 21 is arranged on the lower side in the figure. On the other hand, the pressure member 31 is arranged on the upper side in the drawing.

The conveyance center line Ca of the work table 1 and the conveyance center line Cb of the work table 3 are deviated by a predetermined amount E in the direction orthogonal to the work conveyance direction, that is, the width direction, and the side gauges 17 and 27 correspond to each other. It is provided on the offset side of the transport center lines Ca and Cb. As a result, the distance between the side gauges 17 and 27 in the width direction is larger than the width dimension of the workpiece (conveyed object) W by the predetermined amount E.

Further, the positions of the bending dies 7 and 9 as the processing stations are also deviated from each other in accordance with the deviations of the transport center lines Ca and Cb. In other words, the bending die 7 has a conveyance center line Ca.
The bending die 9 is arranged with the reference line as
Are arranged with the reference line as.

The work tables 1 and 3 respectively have pin gauges 35 and 37 for positioning the workpiece W in the feeding direction (left and right in the figure).
Are provided, and these are arranged at predetermined positions in the feed direction by screw rods 39 and 41, respectively.

According to the configuration as described above, the work W is first pinned on the work table 1 by bending the front edge thereof.
With the amount of feed determined by the pressure member
21 is pressed against the side gauge 17 and positioned in the width direction. In this state, the workpiece W is bent at its front edge by the bending die 7.

Next, with the pressure member 21 retracted, the workpiece W
Is sent to the work table 3 through the bending machine 5 and is pressed against the side gauge 27 by the pressure member 31 in a state where the feed amount is determined by the pin gauge 37, and the positioning in the width direction is newly performed. In this state, the bending die 9 bends the rear edge.

As described above, the workpiece W moves from the section corresponding to the side gauge 17, that is, the section of the work table 1 to the section corresponding to the side gauge 27, that is, the section of the work table 3 after passing through the bending machine 5. At this time, since the transport center lines Ca and Cb in both of these sections are deviated by a predetermined amount E in the width direction, the side gauge 27 is at a predetermined positioning position and does not have to be retracted from the work table. A gap corresponding to the predetermined amount E is present between the workpiece W sent from No. 1 and the side gauge 27. This prevents the workpiece W from colliding with the side gauge 27 when the workpiece W is carried onto the work table 3.

The side gauges 17 and 27 may be fixedly arranged in the above-mentioned positional relationship when the work to be conveyed is one kind and has a constant width. When there are multiple types of objects and the width of the workpiece changes, the side gauges 17 and 27 are guided by the guide rails 43 and 45 to accommodate the width of the work transfer line, as shown in the drawing. It may be provided so that the arrangement position can be changed in the direction.

In the above, the present invention has been described in detail with reference to specific embodiments, but the present invention is not limited to this.
It will be apparent to those skilled in the art that various implementations are possible within the scope of the present invention.
