Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a missing meat inspection device and a transfer press machine equipped with the missing meat inspection device.

For example, automobile panels (front pillars, cross members, outer panels, side door panels, etc.) are generally molded with a press molding machine.
On the other hand, a transfer type press machine is known for increasing productivity.

This transfer-type press machine has a transfer mechanism that arranges a plurality of dies on a set of slides and bolsters and transports the work so that the work is pressed in the order of each process equipped with a plurality of dies. It is prepared.

In the blanking process from the coil material, due to changes in the amount of stamping oil adhering to the material or work, the work and the roll slide on the feeding device (roll feeder), the amount of work supplied from the coil material is shortened, and the normal A problem occurs in which a workpiece shorter than the dimension is blanked.
In drawing (draw) forming, if the work shifts from its normal position due to misalignment during work transfer or wear of the work positioning parts in the mold, the work must be held down by the blank holder during processing. is weakened, the workpiece flows in unevenly, and the end of the material is shortened. In this case, a workpiece shorter than the normal dimension may occur at a position different from the transport direction.
In addition, it is impossible to eliminate human errors in a series of press work processes.
These factors can lead to under-walled workpieces with reduced dimensions in the conveying direction or in different directions, under-walled material with reduced dimensions in the case of metal sheets (eg high-strength steel sheets).

Lack of meat occurs at the periphery of the material. When automobile panels are joined to each other, the periphery of the product is a portion to be joined with other products, and if insufficient wall thickness occurs, the automobile panels cannot be properly joined.
In addition, it is conceivable to add a margin to the outer periphery of the product in advance so that there will be no problem in joining even if a lack of thickness occurs, and trim the excess area in the final process of the transfer press, but the yield of the material will deteriorate. Not suitable for mass production.
It is necessary to have a mechanism that can reliably detect the shortage of meat that has occurred.

On the other hand, in a transfer type press machine, when a workpiece (short-filled material) having a short-filled portion at the end perpendicular to the conveying direction enters, the short-filled material is removed by gripping means (for example, fingers for gripping) constituting the conveying mechanism. The material cannot be gripped.

The gripping means has a sensor for detecting a signal to stop the operation of the press in order to remove the insufficient material when the material cannot be gripped, and the operation of the press is stopped when the sensor does not operate. It is configured so as to stop, and a large underfilled material with a underfilled thickness of 10 mm or more, for example, is not discharged out of the press machine.

However, in the case of the metal plate (having a size of 250 to 1500 mm in the feeding direction in the press process), there may be a thickness of less than 10 mm, especially less than 5 mm.
However, because of the equipment, the gripping means can only be attached on both sides in the direction orthogonal to the material feeding direction by the press machine, so the lack of thickness can be detected in the orthogonal direction (side direction). It is limited to dimensions only, and cannot detect underfill in dimensions in the feeding direction.
Therefore, it is difficult to detect underfill within, for example, 5 mm in the feed direction, which affects productivity.

On the other hand, as a mechanism capable of detecting a small thickness shortage, optical detection forms such as those disclosed in Patent Document 1 are used in most cases.

JP-A-2002-365227

The inspection device of Patent Literature 1 optically detects transmitted light, and in production sites, it may not be applicable to materials waiting in an idle process from the viewpoint of space and surrounding environment. . In addition, it is not suitable for detection of underfill in terms of material dimensions.

Furthermore, when trying to apply it to a metal plate in a transfer type press machine, there remains a problem that the detection stability and rapid detection are not sufficient.

SUMMARY OF THE INVENTION Therefore, the main object of the present invention is to provide a lack of meat inspection apparatus and a transfer type press machine equipped with the lack of meat inspection apparatus that is excellent in detection stability and rapid detection while accurately detecting a shortage of meat.

Therefore, first, the transfer type press machine 1 will be outlined with reference to FIG. 10 .

First, in the embodiment of the transfer type press machine 1, a plurality of molds are arranged on a set of slides 2 and bolsters 3. As shown in FIG. A workpiece (for example, a metal plate, not shown in FIG. 10) is placed between an upper mold 4 arranged on the lower surface side of the vertically movable slide 2 and a lower mold 5 arranged on the upper side of the fixed bolster 3. ) is supplied. This workpiece is pressed between a set of upper and lower dies 4 and 5, and the workpiece after press working is carried out by a conveying mechanism (not shown) and placed between a pair of adjacent dies. supplied and subjected to other types of stamping. In this manner, press working is performed in each step in sequence.
When viewed from the workpiece side, a plurality of pairs of dies are used to perform the pressing process in order.

1 to 3 show an embodiment of a meat shortage inspection device 10. FIG. For example, the missing-meat inspection device 10 is first arranged at an appropriate position of the transfer-type press machine 1 . An example of this arrangement position will be described later with reference to FIGS. 11 and 12. FIG.

The missing meat inspection apparatus 10 includes first side guides 12A and 12B provided vertically on a first side LD (left side in FIG. 2) in a first direction H1 (horizontal direction in FIG. 2) and the first side guides 12A and 12B. It has second side guides 14A and 14B provided vertically on the second side RD (right side in FIG. 2) in the first direction H1 facing the LD.

A first seat 21 is provided on the first side LD at a position closer to the second side RD than the first side guides 12A and 12B. The first seat 21 in the embodiment is the first base plate 41 . The first seat 21 may be separately attached to the first base plate 41, or may be provided on the upper surface 40a of the machine base 40 or the like.

On the other hand, on the second side RD, an upper second upper seat 31 and lower second underwear seats 32A, 32B are provided.
The second upper seat 31 is configured to move back and forth in the first direction H1, and when moving forward, the tip of the second upper seat 31 advances toward the first side from the tips of the second lower seats 32A and 32B. configured to

The second upper seat 31 is above the second lower seats 32A, 32B in the embodiment.
In other embodiments, for example, the second underwear seats 32A and 32B are not provided, or the second underwear seats 32A and 32B extend toward the first side LD from the second side guides 14A and 14B, but the Since the degree of extension is small, there is also proposed a configuration in which the extension edges of the second lower seats 32A and 32B are disengaged at the position where the second upper seat 31 is retracted to the limit.
In these modes, when the work W falls off the second upper seating 31, it sits on the upper surface of the second base plate 42 or the upper surface 40a of the machine base 40 below.

In the embodiment, the second lower seats 32A and 32B are provided at positions sandwiching at least one second upper seat 31 in plan view in a first direction H2 that intersects with the first direction H1. . The second base plate 42 may be used as the second bottom seats 32A and 32B, or may be provided on the upper surface 40a of the machine base 40 or the like.

In addition to the first side guides 12A, 12B and the second side guides 14A, 14B, side guides 16 can be provided on one side or both sides in the second direction H2.
In the embodiment, the first side guides 12A, 12B, the second side guides 14A, 14B, and the side guides 16 are formed with inclined surfaces at the upper portions thereof, and the work W (for example, a plate-like body) is supplied downward from above. The side surface of the steel plate) is guided and placed at a predetermined position, so that the work can be positioned to the engaging portion P1.

In the transfer-type press machine 1, the first direction H1 can be the feeding direction of a work (for example, a steel plate).
The direction in which the first side guides 12A, 12B and the second side guides 14A, 14B face each other is not limited to the feeding direction of the work as shown in FIG. It can be freely changed as appropriate in plan view in correspondence with the direction.

Each of the above-described elements of the missing meat inspection apparatus 10 is provided on, for example, a machine base 40, a first base plate 41 is provided above the machine base 40, and the upper surface of one side of the first base plate 41 serves as a first seating. 21.
A second base plate 42 is provided facing the first base plate 41, and the second side guides 14A, 14B and the second bottom seats 32A, 32B are fixed to the second base plate 42. As shown in FIG.
The upper surfaces of the second underwear seats 32A and 32B are approximately the same height as the upper surface of the first base plate 41. As shown in FIG.

As described above, the second upper seat 31 is configured to move toward the first seat 21 in the first direction H1. In the embodiment, the second upper seat 31 is fixed to the intermediate guide 34 .
A forward/reverse cylinder 33 is fixed to the second base plate 42 , an intermediate guide 34 is fixed to a rod of the forward/reverse cylinder 33 , and the second upper seat 31 is configured to move forward and backward together with the intermediate guide 34 .
The tip of the second upper seat advances to a position displaced to the first side from the second lower seat when the second upper seat advances.

In order to stabilize forward and backward movement, the second base plate 42 is formed with a guide groove 42a along the first direction H1, in which a slider (not shown) that moves together with the intermediate guide 34 is slidably fitted. there is

In the embodiment, the second upper seat 31 is fixed to and integrated with the intermediate guide 34 .
Moreover, although the second underwear seats 32A and 32B are formed separately, they may be a continuous integral member (for example, a plate).

Missing meat is detected as follows. Modes of meat shortage detection are shown in FIGS. 4 to 7. FIG.
Fingers 1</b>F as grasping means provided in the operation of the meat shortage inspection apparatus 10 and in the conveying mechanism are configured to interlock with the feed angle of the press machine 1 .

That is, the slide of the press machine 1 repeats up-and-down reciprocation while indicating the next feed angle.
・First angle range (0 degrees → 90 degrees): Angle range from top dead center to midpoint ・Second angle range (90 degrees → 180 degrees): Top die from midpoint to bottom dead center 3rd angle range (180 degrees → 270 degrees): The angle range from the bottom dead center to the middle point of the upper die 4th angle range (270 degrees → 0 degrees): The upper die Angular range from midpoint to top dead center

(first step)
First, as shown in FIG. 4, a work W gripped by fingers 1F as gripping means provided in a transfer mechanism of the transfer-type press machine 1, for example, is transferred onto the missing-meat inspection device 10 and lowered from above. The grip is then released.

As a result of the release of the grip, the work W falls under its own weight between the guides 12A, 12B, 14A, and 14B and is put into the meat shortage inspection apparatus. When the work W falls, it first contacts P2 on the second upper seat 31, and the descent of one end is stopped. After that, the left end (the other end) of the work W is placed on the first seat 21 on the first base plate 41 and the corners of the first guides 12A and 12B due to its own weight, regardless of the length of the work (whether or not there is a lack of thickness). It is locked by the locking portion P1 to be formed, and the position is fixed.
As a result, the work W is in an inclined state (a state having a first angle The bottom surface is inclined at a first angle θ1, which is the angle formed with the horizontal line passing through the engaging portion P1).
The first angle θ1 is preferably 15 to 45 degrees. If the first angle θ1 is too small, it will be difficult for the workpiece W to clearly shift from the state shown in FIG. 5 to the state shown in FIG. The locking onto 31 tends to be unstable.

(second step)
Next, as shown in FIG. 6, when the second upper seat 31 moves backward together with the intermediate guide 34, the front end of the work W comes off the second upper seat 31 and falls. At this time, since the workpiece W is fixed at the engaging portion P1 on the first seat 21 on the first base plate 41, it rotates clockwise in FIG. A second angle θ2 (the angle formed by the bottom surface of the workpiece W and the horizontal line passing through the engaging portion P1) is formed with respect to the direction.
The second angle θ2 is smaller than the first angle θ1, and is preferably an angle that allows the fingers 1F to grip the workpiece W. From this point of view, the second angle θ2 is preferably +5 degrees to -5 degrees. Within this angle range, it is easy to determine whether or not there is a lack of thickness. In an embodiment, the second angle θ2 is approximately 0 degrees with respect to the horizontal direction.

Here, if the work W is within a predetermined front-to-rear dimension range, the front end of the work W is placed on the second underwear seats 32A, 32B and maintained in a substantially horizontal state. In this state, unloading by the finger 1F is possible.

(Third step)
The finger 1F is provided with a sensor (not shown) that constitutes means for detecting whether or not the workpiece W can be gripped. ), the sensor operates, and it is judged to be normal by the control means (not shown), and as shown in FIG. be done.

On the other hand, in the case of a work W (short-cut material) having a short dimension that is less than the predetermined front-to-rear dimension range, the distance from the locking portion P1 of the first seating to the second underwear seats 32A and 32B is the above-mentioned As shown in FIG. 7, when the front end of the work W comes off the second upper seat 31 and falls, it is not placed on the second lower seats 32A and 32B, and the second base plate 42 or the upper surface 40 a of the machine base 40 .
As a result, the front side of the workpiece W straddling the first seat 21 on the first base plate 41 and the second base plate 42 or the upper surface 40a of the machine base 40 is inclined downward.
In this state, the sensor attached to the finger 1F does not operate, and the control means determines that there is an abnormality, and stops the press. As a result, the workpiece W is not carried out of the meat shortage inspection apparatus 10 to the next pressing step, and is then removed by an operator or other carrying-out means (not shown).

The first step, second step and third step are executed based on the feed angle of the work. As an example of the feed angle, the angle when the gripping of the fingers in the first step is released is 90 degrees, the angle when the second upper seat 31 moves backward together with the intermediate guide 34 in the second step is 180 degrees, and the workpiece in the third step is 90 degrees. The gripping angle can be 270 degrees. This feed angle is merely an example, and can be changed as appropriate according to the type of transfer press machine, the working speed of the press machine, and the like.
As described above, the loading and transfer of the work by the operation of the lacking meat inspection device and the operation of the fingers are performed based on the feed angle of the press machine. Therefore, even if the processing speed of the press machine is increased in order to increase productivity, the timing of loading and transporting the workpiece and the operation of the lack of thickness inspection device do not deviate, making it possible to stably detect the lack of thickness.

In addition, if the second upper seat 31 were not provided, the work W would drop by its own weight and would fall along the first side guides 12A, 12B and the second side guides 14A, 14B. There is a possibility that the workpiece W will tilt and fall due to the vibration of the machine. The front side of the work W, which straddles the two base plates 42 or the upper surface 40a of the machine base 40, is inclined downward (see FIG. 5A).
As a result, the sensor attached to the finger 1F does not operate for the work W which is not actually underfilled, and the control means determines that there is an abnormality, and the press machine is stopped.
On the other hand, if the second upper seat 31 is provided, there is an advantage that the front end of the work W can be supported by the second upper seat 31 even if the work W tilts and falls.

According to the meat shortage inspection apparatus 10 of the embodiment, the work W that is thrown in in an unstable posture is tilted with one end thereof in contact with P2. As a result, the other end of the work W abuts against the engaging portion P1 and is fixed, so that the end of the work can be reliably positioned.
By positioning the other end of the work, it becomes possible to determine the length of the work W (whether or not there is insufficient thickness) based on whether or not one end of the work is placed on the second underwear seats 32A and 32B.

On the other hand, if the workpiece W is dropped between the guides 12A, 12B, 14A, and 14B by its own weight without being positioned by the second upper seat 31, the workpiece wobbles due to the vibration of the press machine, etc. Since the position of the workpiece W fluctuates in the left-right direction on the upper first seat 21 and on the second lower seats 32A and 32B, reliable positioning cannot be performed, and highly accurate detection cannot be performed.

By using the lack of meat inspection apparatus 10 of the embodiment, it is possible to distinguish between a non-defective product in which one end of the work is placed on the second lower seats 32A and 32B and a defective product in which one end of the work is not placed. With the attached sensor, it can be easily determined without false detection.

The lack of meat inspection apparatus 10 of the embodiment can mechanically determine the dimensions of the workpiece with high precision, so that the lack of meat can be stably detected. Moreover, since the lack of meat is detected directly, the speed of detection is excellent.

The lack of meat inspection device 10 can be provided, for example, in an idle process, and in the idle process, the work can be dropped between the guides 12A, 12B, 14A, and 14B to detect the dimensions of the press machine. No impact on productivity.

In the conventional optical product inspection, there is a limit to high detection accuracy due to reasons such as the posture of the workpiece W being carried in is not constant, and rapid transportation from loading to unloading is required. It is not suitable for the transfer type press machine 1 that is used.
In short, the missing meat inspection apparatus 10 of the embodiment is highly accurate and excellent in detection stability and detection speed.

Conventionally, a sensor detects whether or not each finger 1F can grip at both edges in the second direction H2 (the direction perpendicular to the feed direction), and this is used to detect insufficient thickness. rice field.
On the other hand, according to the lack of meat inspection apparatus 10 of the embodiment, in the case of a metal plate (the dimension in the feeding direction (first direction H1) in the pressing process is, for example, 25 to 150 cm), the feeding direction , it has been found that it is possible to detect underfill within 10 mm, particularly within 5 mm.
This means that, for a metal plate having the shape shown in FIG. 13, for example, the lack of thickness detection in the L2 direction can now be detected by the lack of thickness inspection apparatus 10 in the L1 direction. ing.
Furthermore, for example, by providing the guides 12C and 14C, it becomes possible to detect the lack of thickness in the L3 direction.
By adjusting the positions and lengths of the second underwear seats 32A and 32B, the detection accuracy can be easily changed according to the product tolerance.

If necessary, various modifications can be made to the lean meat inspection apparatus 10 of the embodiment. For example, as shown in FIG. 8, the second lower seats 32A and 32B may be connected to rods of forward and backward cylinders 33A and 33B in the same manner as the second upper seat 31 so as to move forward and backward.

When the workpiece has a non-rectangular planar shape, for example, an elliptical workpiece W1 as shown in FIG. The position and orientation can be changed as appropriate.

A plurality of second upper seats 31 may be provided at different positions in plan view. Similarly, the number of second underwear seats can be selected as appropriate.

The missing meat inspection device 10 can be incorporated into the transfer press machine 1 .
The transfer type press machine 1 is as described above.
The transfer mechanism of the transfer type press machine 1 is configured to grip the workpiece W carried into the meat shortage inspection device 10 and carry it out to the next mold, and includes gripping means having fingers 1F, for example. ing.
The gripping means has means for detecting whether or not the workpiece W can be gripped (for example, the sensor), and when the workpiece W cannot be gripped, the means for detecting whether or not the workpiece can be gripped sends a signal to the press machine to stop its press operation. I try to give. Since the press machine stops automatically, it is easy to detect materials with insufficient thickness.

The arrangement of the meat shortage inspection device 10 can be selected as appropriate.
For example, an idle process portion can be provided in the arrangement of a series of dies of the transfer type press machine 1, and the lack of meat inspection device 10 can be arranged at that position. The idle process is an idle process in which molding is not performed. Compared to installing an inspection device outside the press machine line, it is possible to save space in the factory.

On the other hand, in the transfer type press machine 1 for molding, as shown in FIG. 11, the lacking inspection device 10 can be provided at a position after the molding process DR in the arrangement of the plurality of molds.
Reference numerals 1A to 1D indicate other processes such as a trimming process, a lower drilling process, a lateral drilling process, and a bending process.
A workpiece with a complicated shape after molding is likely to have shadows within the workpiece, making it difficult to inspect with a camera or the like. On the other hand, the missing meat inspection device 10 is for directly inspecting the product width. Therefore, by arranging the missing-meat inspection device 10 in a process after the molding process DR, it is possible to easily inspect even a workpiece having a complicated shape after molding without being affected by the shadow of the product or the like.

On the other hand, in the transfer type press machine 1 for blanking, as shown in FIG. 12, the lacking meat inspection device 10 can be arranged in the first process in the arrangement of a plurality of molds.
Reference numerals 1E to 1H indicate other processes such as a forming process, a trimming process, a lower hole drilling process, a lateral hole drilling process, and a bending process.
By arranging the lack of thickness inspection device 10 in the first process, the lack of thickness of the plate-shaped material can be inspected at the stage of supplying the transfer type press machine 1 .
When a material with a lack of thickness is formed, for example, when the forming process is a drawing (draw) forming process, the holding of the work by the blank holder deteriorates, and the inflow of the work increases, causing problems such as wrinkles. When molding, bending, cutting, etc., are performed on a work wrinkled in the molding process, damage to the mold occurs from the wrinkled portion. Such a problem can be solved by arranging the missing meat inspection apparatus 10 in the first process.

Although the embodiment inspects for lack of thickness in the conveying direction, it can also be used in the orthogonal direction by changing the orientation. The sensor may be a workpiece presence/absence detection sensor provided on the finger. The locking portion P1 may be a protrusion, a recess, a hook shape, or the like provided on the upper surface of the seat other than the corner portion between the guide and the seat portion. The fingers are a pair of left and right fingers in the direction in which the dies of the transfer press are arranged, and are conveying devices that hold both ends of a workpiece and convey it from one die to the next in sequence. A magnet gripper, suction pad, or the like should be able to detect the workpiece orientation (angle, etc.) with a sensor. If the lack of thickness of the workpiece occurs in two directions, that is, the direction of conveyance and the direction perpendicular to the direction, the present invention should also prepare two sets so that it can be detected in the two directions.

The lack of meat inspection apparatus according to the present invention can be installed independently of the press machine, and the object to be detected is not only a metal plate (steel plate), but also a plate-shaped object molded vertically or having a non-rectangular circumference. may
