Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a mixed production line or the like in which similar workpieces are conveyed on the same line and assembled into different types of products, and the present invention provides a method for determining which type of workpieces should be specifically assembled into. The present invention relates to a conveyed article type display device that displays the type of conveyed articles in the order of conveyance.

For example, on a mixed production line for cars of the same model, there are not only differences in models and grades such as 2-door and 4-door cars, but also items to be assembled within the grade, such as the color of the seat, etc.
The patterns etc. are different.

By the way, in the manufacture of automobiles, a daily production plan is determined by a computer, and bodies are transported on a production line in a predetermined order, and each body is assembled into a predetermined automobile. In this type of production line, it is therefore necessary for workers to recognize what kind of car model the body being transported is compatible with, and to assemble parts according to that car model, etc. In many cases, it is difficult to determine the body being transported just by looking at it, and instructing this using a computer is difficult due to differences in work time in each process, difference in transport time between work positions, etc. In fact, it is almost impossible to do so, and in the field, extremely primitive and inefficient methods of confirming the type are being implemented, such as handing over type display boards that display the type and pasting paper with specifications recorded on the body. That was the current situation.

The present invention focuses on the fact that the production order is known in advance, solves this problem, and has a simple structure that allows for reliable and easy sequential delivery of articles and parts to be assembled. It is an object of the present invention to provide a device for displaying the type of conveyed articles, which allows confirmation of the types of conveyed articles.

In other words, in the example of automobile manufacturing, it is of course necessary to identify the pod itself being transported and select the welding procedure.
In addition to displaying the car model, model, grade, etc., in the seat assembly workplace it should be displayed which of the eight types of seats will be assembled, and in other places it should be displayed which of the three types of handles. It is intended to be something that can be used to instruct one or the like.

Therefore, in the present invention, the plates have the same thickness, have positioning reference parts, and have the same external shape,
A case with upper and lower openings that can support the detection plates in a stacked manner is provided with a large number of detection plates having detection parts at different positions around the periphery depending on the type of conveyed article, and a reference guide part corresponding to the positioning reference part of the detection plates. , a take-out mechanism that is movably provided on the lower opening side of the case, and that takes out the lowest one of the stacked detection plates to the outside of the case, and sequentially moves the upper detection plates downward, and a certain height of the case. A plurality of detectors are provided around the detector facing the detection part of the detection plate to be detected, and in response to a detection signal from any one detector, the conveyed article itself or assembled parts corresponding to the detector is detected. The basic feature is that the detection plates are stacked in advance in correspondence with the order of conveyance of the conveyed articles, and a predetermined signal is displayed in the order of conveyance.

The detection plate according to the present invention can have any planar shape, but preferably has a shape convenient for handling, such as a circle or a square.

Further, the detection part provided on the detection plate may be one that can be identified and detected by a change in shape such as a protrusion or notch, and may be fixed by pasting a metal piece around the insulator plate. However, it may be something that can be detected electrically or magnetically.

Hereinafter, the present invention will be described in more detail based on illustrated embodiments.

In FIG. 1, 1 is a table forming the main body of the device, 2
There are a total of four support frames 3 in the center of the table 1,...
, 3 is a storage case for a cylindrical detection plate whose lower end is floatingly supported on the table surface 1a with a gap c slightly larger than the thickness of the detection plate, which will be described later. A detector consisting of a proximity switch arranged at a predetermined angular pitch around the lower end of the case 2 serves as a detection position in the storage case 2.

Reference numeral 5 denotes a take-out plate that takes out the lowest detection plate from the gap c at the lower end of the storage case 2 and discharges it into the chute 6. Reference numeral 7 denotes a rotary actuator that drives the take-out plate 5 back and forth between the detection position and the release position. , these take-out plates 5 and rotary actuator 7 constitute a take-out mechanism A.

In response to the detection signal of one of the detectors 4, 8 indicates the type of article (for example, car model) corresponding to that detector 4, or the part to be assembled (for example, a sports specification seat).
This is a display device that displays the following information.

Note that this display may be installed independently on multiple panels.
Alternatively, it may be digitally displayed on a single display section. As shown in FIGS. 3 and 4, the detection plate 9
, . . . , 9 is formed as a plastic disk having a certain thickness, and includes a groove 9a extending in the radial direction from the outer periphery to the center of the disk, and a recess formed at a constant interval from the groove 9a. 9b as a common structure for all detection plates 9, each detection plate 9 has a metal piece at the outer circumferential position corresponding to the number to be displayed and divided based on the positioning reference part B. 10 is fixed, for example, by gluing, and this metal piece 10 forms a detection part for identifying the type of conveyed article or parts to be assembled.

Therefore, for example, if the metal pieces 10 are fixed at an angular pitch of 20, the cut grooves 9a and the recesses 9
One fixed position can be selected between the two positions, and 11 corresponding displays are possible. As shown in FIG. 5, the detectors 4, . . . , 4 are provided with mounting openings 11, . , 11 in a radial manner, and each detector 4 detects where on each detection plate 9 the metal piece 10 is fixed.

The above-mentioned detection plates 9, .
are stored in the storage case 2 in that order in a stacked state from above.

As shown in FIGS. 2 and 5, the storage case 2 includes
A first guide 12 that fits into the cut groove 9a of the detection plate 9 and guides the detection plate 9 in the vertical direction is provided in the radial direction, and a second guide 13 that fits into the recess 9b of the detection plate 9 faces inward. The first and second guides 12 and 13 constitute a positioning guide C, which positions the detection plate 9 to be stored and allows it to be stored without making a mistake between the front and back sides.

Further, the take-out member 5, which is reciprocated between the detection position and the discharge position by the rotary actuator 7, detects one side of the outer periphery of the fan-shaped plate material having a right-angled central angle, as shown in FIG. It has a notch 5a cut out in a semicircular shape so that the plate 9 can be fitted, and as shown by the imaginary line S, the notch 5a is located directly below the storage case 2 at the reset position, and the reset When it is rotated from the position S to the solid line position in the figure, the lowest detection plate 9 is carried to the pit 14 of the table 1 and discharged into the chute 6.

At this time, the next detection plate 9 at the lowest position is held as it is in the storage case 2 by the remaining plate part 5b, and at that stage, the detection for the lowest detection plate 9 in the storage case 2 is performed. . In this detection, a number of detectors 4,...,4
When one of them outputs a detection signal in response to the metal piece 10 of the lowest detection plate 9, that signal is transmitted to the display 8, and the display 8 detects the next article to be transported or to be assembled. Displays the type of parts to be used.

Then, necessary assembly work is performed on the transported article according to the displayed type, and when the article is sent to the next work position, the take-out plate 5 is moved to the rotary actuator 7.
The saw is reciprocated and the lowest detection plate 9 is moved to the chute 6.
The next conveyed article and the type of parts to be assembled are displayed on the display 8 in the same manner as described above. In the above embodiment, the detection plate 9 is made of a plastic disk, and the metal piece 10 is pasted around it to form the detection part, but the shape and material of the detection plate 9 are not particularly limited to this. As described above, the detection section may also have a mechanical structure such as a convex portion or a concave portion, and may be detected by a suitable detector such as a feeler.

As is clear from the above, the present invention can sequentially display the types of conveyed articles and parts to be assembled by simply stacking detection plates in the case in advance in accordance with the order of conveyance of the articles. The present invention provides a display device for conveyed articles that is transparent.

According to the present invention, by stacking the detection plates in advance in the case in the order in which the conveyed articles are supplied, it is possible to display the types of parts to be assembled with the conveyed articles as the detection plates are taken out from the lower end, Furthermore, since the detection plate has a positioning reference part and the case has a positioning guide, it is possible to prevent stacking errors and reliably prevent detection errors.

Furthermore, since the detection is performed within the case where the detection plate itself is positioned, there is no need to move the detection plate to another position outside the case for detection and position it again, making it a simple device. .
