Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a hemming machine hemming device that automatically unscrews a processed workpiece from a hemming machine and transports it to a take-out position.

(Prior Art) In a conventional hemming machine spring release device, generally, as shown in FIGS. Push out the material on the conveyance line 2 to the extraction zone 3 (dotted line arrow in the same figure).
Alternatively, as shown in Figure 2 a and b, scoop it up from the hemming zone 1' with an arm,
Convey it to the take-out zone 3' in an upright state (in the same figure,
Dotted line arrow) A spring-out method is adopted.

However, in the case of the spring-out method shown in Fig. 1,
Person A sets workpiece W in hemming zone 1
The hemming zone moves to the take-out zone 3 side to take out the workpiece W, but there is generally a considerable distance between the hemming zone 1 and the take-out zone 3, which increases the labor burden on the worker. I had no choice but to be strict. Furthermore, with such a layout, the spray device itself had to be enlarged, and there was also the inherent problem of increased equipment investment costs.

On the other hand, in the case of the hemming method shown in Fig. 2, although the hemming device itself can be made smaller, the work zone is divided and cannot be handled by one worker, and the work W is set in the hemming zone 1'. The problem has been that two people are required: person B to take out the workpiece W and person C to take out the workpiece W in the takeout zone 3', which increases personnel costs accordingly.

(Purpose of the invention) In view of the problems of the prior art described above, the present invention provides a hemming machine snap-out device that can be made as small and inexpensive as possible, and that can contribute to reducing the labor burden and saving labor. With the goal.

(Structure of the invention) The purpose is to provide a plurality of transport rollers that are movable up and down on a base adjacent to the main body of the hemming machine, and link actuators that are provided to move up and down following the transport rollers. a hemming machine bar, a parallel link provided on the hemming machine and operated by engaging with the bar, a lifter for taking out a workpiece attached to the parallel link, and a workpiece takeout swingably provided on the base. This is achieved by a hemming machine splash removal device that includes a roller, a chute provided below the workpiece takeout roller, and drive means for the conveyance roller and workpiece takeout roller.

(Example) Hereinafter, an example of the present invention will be described based on the accompanying drawings.

Figures 3 and 4 show an example of the structure of the hemming machine snap-out device according to the present invention, where Figure 3 is a front view and Figure 4 is a view taken in the direction of the arrows in Figure 3. . In these figures, 11 is a hemming machine main body, 12 is a spring removal device main body, and the spring removal device main body 12 is collectively provided on a base 13 slightly to the side of the hemming machine main body 11.
Reference numeral 14 designates a first support post erected at a rear position on the base 13. A first bracket 16 is protruded from a support base 15 installed on the top of the support post 14. 1 cylinder 17 is installed,
The piston rod 18 is extended downward.
On the other hand, a second bracket 20 is protruded rearward from a support plate 19 installed at the lower end of the first column 14, and a link arm 22 whose tip end is branched left and right by a shaft portion 21 is pivotally attached to the second bracket 20. It is worn. The piston rod 18 of the first cylinder 17 is pivotally connected to the shaft portion 21 of the link arm 22.
As a result, if the first cylinder 17 is driven,
The link arm 22 swings up and down.

23 is a pair of guide rods arranged on the left and right between the base 13 and the support 15;
A sliding member 24 is slidably provided on each of the. The sliding member 24 engages with the tip of the link bar 22, and is connected to first supporting members 25a and 25b for supporting conveyance rollers.
The transport rollers 26a, 26b, 26c are supported by the first support members 25a, 25b. That is, the conveyance rollers 26a, 26b, 2
6c is connected to the first cylinder 17 via the sliding member 24 and the link bar 22, and moves up and down following the driving of the first cylinder 17. Note that 27 is a link operating bar, which will be described later, which is fixed to the first support member 25b.

On the other hand, the hemming machine main body 11 has a parallel link 2.
8 is provided, and the parallel link 28 is provided with a lifter 29 for removing workpieces. However,
Now, when the first cylinder 17 is driven and the first support member 25b and therefore the bar 27 rises,
The parallel link 28 engages with the bar 27 and is lifted upward, and the workpiece spring-out lifter 29 operates accordingly.

Further, a second cylinder 30 is mounted on the base 13.
and a second support member 31 are swingably disposed as appropriate, and the second support member 31 engages with a piston rod 32 of the second cylinder 30. 3
3 is a workpiece take-out roller, and the swingable second
A chute 3 supported by a second support 33' standing on the base 13 is provided below the workpiece take-out roller 33.
4 are arranged at a predetermined angle of inclination. Note that 35 and 36 are guide members for regulating the movement of the workpiece, which will be described later.

With such a configuration, when it is confirmed that the hemming process is completed in the hemming machine main body 11, the second cylinder 30 is first driven, and following this, the second support member 31 moves in the direction of arrow D (fourth arrow). The workpiece take-out roller 33 is raised by swinging as shown in the figure. When it is confirmed that the workpiece take-out roller 33 has risen, the first
The cylinder 17 is driven, and its driving force is transmitted to the sliding member 24 via the link arm 22, and the sliding member 24 is thereby driven by the conveying rollers 26a, 26
b and 26c rise as shown by arrow E (Figs. 3 and 4). These conveyance rollers 26a, 26b, 26
The bar 27 also rises in conjunction with the rise of c, and the bar 27
engages the parallel link 28 and moves it along the F arrow (third
Move it upward as shown in the figure).

As a result, the lifter 29 is actuated to push up the hemmed workpiece in the direction of arrow G (Fig. 3) and send it out to position W' in Fig. 3. At this time, the conveyance rollers 26a, 26b, and 26c are on the extension line of the lifted lifter 29 (shown by the chain line in FIG. 4), and as a result, the sprung workpiece is moved under its own weight by the H arrow (FIG. 3). It moves to the right as shown in FIG.
Stops at W″ position.

Subsequently, the first cylinder 17 is driven again to lower the conveyance rollers 26a, 26b, and 26c, and then, with a slight delay, the second cylinder 30 is driven and the workpiece take-out roller 33 swings. As a result, the workpiece located at the W' position is supported by the workpiece take-out roller 33 and sent to the chute 34.
It moves from the top to the bottom, and during this time, its posture is gradually corrected until it reaches position W in FIG. 4, and at this stage it is taken out by the worker.

As is clear from FIG. 3, the workpiece position W' that has been taken out from the hemming machine main body 11 and the workpiece position W'' that has moved toward the take-out zone side are in a state where they overlap with each other, and therefore, The worker who has set the workpiece in the hemming machine body 11 can take it out by simply moving slightly to the right, which not only requires only one person but also significantly reduces the labor burden. This will be reduced.

Note that the drive means for the conveyance rollers 26a, 26b, and 26c and the drive means for the workpiece take-out roller 33 are not limited to the above embodiments, and may be provided by combining a cylinder mechanism and a link mechanism as appropriate.
Also, depending on the shape of the workpiece, the conveying roller 26a,
26b, 26c, the workpiece take-out roller 33, the guide members 35, 36, etc. can of course be appropriately arranged or replaced.

(Effects of the invention) As explained above in detail, the hemming machine snap-out device according to the present invention appropriately arranges the conveyance roller and the workpiece take-out roller, and connects these with the lifter on the hemming machine main body side. The device is designed to operate at the right timing, making the splash removal device as compact as possible. This not only enables workers to work more efficiently and reduces their labor burden, it also has the effect of reducing the number of personnel due to labor savings, and also reduces equipment investment costs. The effect was achieved.
