DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. The work checking device 1 of the present embodiment is provided on a work loading stage such as a transport traverser (not shown). As shown in FIG. 3, the work confirmation device 1 includes a work loading frame 11 on a base frame 10. The work loading frame 11 can reciprocate in a direction indicated by an arrow in the figure from a horizontal position shown in FIG. 2 to an oblique position shown in FIG. 3 around a horizontal axis 12. I have.

[0007] A cylinder mechanism 15 such as an air cylinder is provided between the base frame 10 and the work loading frame 11. When the rod 16 of the cylinder mechanism 15 operates to the contraction side, the work loading frame 11 rises to the oblique posture shown in FIG. 3, and when the rod 16 operates to the extension side, the work loading frame 11 is shown in FIG. It will be horizontal.

The work loading frame 11 is formed by assembling a plurality of frame members 17 into a shape generally corresponding to the work A. Actually, there are six types of work that can be put on the work loading frame 11, for example, or more than six types. However, in the illustrated example, three types of works A ₁ , A ₂ , A ₃ (trunk lid) Alternatively, only the outline of the tailgate) is shown. The form of the work varies depending on the vehicle type.

A work positioning portion 20 is provided at the left end of the work loading frame 11 as a reference point when the work A is placed on the frame 11. Regardless of the type of the work A, the work positioning unit 20 can align the position of the work A by abutting the end 21 of the work A. Also, the frame 11
A work holding portion 23 for holding each work A at a correct position is provided at an appropriate position.

The work A is located near the work positioning unit 20.
Is provided with a sensor 25 for detecting the presence / absence of the presence. Also,
Vehicle type detection sensors 26, 27, and 28 for detecting the type of the work A are provided at appropriate positions on the frame 11. The vehicle type detection sensors 26, 27, and 28 are arranged at positions corresponding to the shape of each work A, and can identify the type of the work A placed on the frame 11.

Each of the sensors 25 to 28 may employ an appropriate detection means such as a well-known proximity switch, and the arrangement of the sensors may be appropriately set according to the type, number, and shape of each work A. In addition to the sensors 26, 27, and 28, a hinge abnormality detection sensor (not shown) that can detect whether the hinge portion of the work A is in a normal state is provided.

The vehicle type setting panel 30 shown in FIG. 4 is basically operated by the operator himself when the operator places the work A on the frame 11 in accordance with the production order.
For example, the control unit 31 is built in the vehicle type setting panel 30 and the like, and when the operator selectively operates any one of the plurality of operators 33 according to the type of the work A, each of the operators 33 The type of the corresponding setting work is input to the control unit 31. The operation element 33 also serves as a lamp for displaying the set vehicle type. The control unit 31 may be provided in a control device (not shown) using a computer.

The control unit 31 checks the type of the set work input to the vehicle type setting panel 30 with the type of the actual work A detected by the sensors 26, 27, 28. Then, when the set work and the actual work do not match each other (vehicle type unmatch), the operator is informed by the notification means. As an example of the notification means, a buzzer 35 or an unmatch indicator light 36 is used. Further, an indicator light 37 is provided for notifying an abnormal mounting angle of a hinge portion of a work such as a tailgate.

Next, the operation of the device 1 will be described. When the work A is placed on the work loading frame 11, the work loading frame 11 is inclined as shown in FIG. In this state, the work A is loaded with the work loading frame 11.
, The end portion 21 of the work A is supported by the work positioning portion 20 so that the work A is aligned with the reference point. The presence / absence of the work A is detected by the work presence / absence detection sensor 25, and the work A
The type of the work A is also determined by operating the sensors 26, 27 and 28 according to the type of the work A.

For example, a first work A ₁ is detected by a first sensor 26, a second work A ₂ is detected by a second sensor 27, and a third work A ₃ is detected by a third sensor 28. And so on.

The type of the work A detected by the sensors 26 to 28 and the type of the set work input to the vehicle type setting panel 30 are collated in the control unit 31. When the two coincide with each other, the rod 16 of the cylinder mechanism 15 moves to the extension side, whereby the work loading frame 11 is
Is displaced to the horizontal state shown in FIG. In this way, the work A is leveled, and is ready to be transferred to a transfer device such as a transport traverser.

When the type of the work A detected by the sensors 26 to 28 is different from the type of the set work input to the vehicle type setting panel 30, the buzzer 35 sounds and the unmatch indicator light 36 is turned on. This informs the operator of the occurrence of the vehicle type unmatch. In this case, the cylinder mechanism 15 does not operate.

In the above embodiment, the set work (vehicle type) input by the worker is collated with the type of work detected by the sensors 26 to 28. However, in implementing the present invention, For example, the vehicle type data input to the computer in advance according to a predetermined production order may be collated with the type of work detected by the sensors 26 to 28.

[0019]

[Effect of the Invention] According to the present invention, the carrying state of the inclined state.
An operator simply places a panel-shaped work on the frame
Work that has already been entered by the setting panel.
The type is compared with the actual work type on the frame, and
Only when the frame is in the unloading position.
If they do not match, the rotation of the frame is restricted.
To inform the worker of the mismatch of the work by the notification means
Therefore, it is possible to prevent a work other than a predetermined work predetermined according to a production order or the like from being erroneously flown to the line of the next process, and to reliably and easily place the predetermined work in a correct posture. Can be sent out.
