[First Embodiment]
FIG. 1 is a plan view showing a schematic configuration of a product production apparatus 1 according to the first embodiment of the present invention.

  A product production device (hereinafter sometimes simply referred to as “production device”) 1 produces a product by flowing the workpiece W from upstream to downstream by a conveying means such as a belt conveyor, and processing the workpiece W. It is a device to do. The production device 1 produces a semi-finished product from the workpiece W, a semi-finished product production device, or a semi-finished product (semi-finished product that has become more similar to the product due to processing, etc.). It may be thought of as a device that

  In the present specification, the inspection of the workpiece W (for example, the measurement of the shape and dimensions of the workpiece W) is included in the concept of producing a product from the workpiece W.

  The production apparatus 1 includes a base member (not shown). The base member includes a drilling device 3 that is an example of a working unit that processes the workpiece W, and a working unit that assembles parts to the workpiece W. An assembling apparatus 5 as an example and an inspection apparatus 7 as an example of a working means for inspecting the workpiece W are provided in order from the upstream side to the downstream side in the flow direction of the workpiece W.

  A pallet supply device 9 for supplying a pallet P for placing the workpiece W to the production device 1 is provided on the upstream side of the drilling device 3, and a workpiece is provided on the downstream side of the inspection device 7. A pallet discharge device 11 for discharging the pallet P for placing W from the production apparatus 1 is provided.

  On the belt conveyor (conveying means), work stations ST1 to ST5 are sequentially formed from the upstream side to the downstream side in the flow direction of the workpiece W. That is, the pallet P placed on the belt of the belt conveyor by the pallet supply device 9 is intermittently sent in order from the station ST1 to the station ST5 when the belt conveyor is intermittently driven appropriately. It has become.

  A work storage shelf 13 capable of storing a plurality of works W is provided on the upstream side of the production apparatus 1, and a product storage shelf 15 capable of storing a plurality of products is provided on the downstream side of the production apparatus 1. Is provided.

  When the workpiece W is supplied from the workpiece storage shelf 13 using a workpiece supply device such as a robot (not shown) onto the pallet P supplied from the pallet supply device 9 to the station ST1, the supplied workpiece W is transferred to the pallet P. At the same time, the belt conveyor sequentially feeds the stations ST2 to ST5 downstream.

  In the station ST2, a hole is drilled in the workpiece W by the drilling device 3. In the station ST3, the component E is assembled by the assembly device 5 in the workpiece W in which the hole has been drilled. The inner diameter d of the assembled workpiece W is measured by the inspection device 7.

  The product (workpiece) W whose inner diameter d has been measured at the station ST4 is conveyed to the station ST5 by a conveyor. At the station ST5, the product W placed on the pallet P is supplied with a workpiece discharge device such as a robot (not shown). And stored in the product storage shelf 15. Further, the pallet P that has run out of the product W is unloaded from the station ST5 by the pallet discharging device 11.

  Each of the stations ST1 to ST5 is provided with a sensor (for example, a photoelectric switch) 17 for detecting the presence of the work W. After the work W conveyed by the belt conveyor is detected by the sensor 17, the work W Work such as drilling is to be performed.

  The station ST2 is provided with discrimination means (not shown) for detecting (discriminating) whether or not the drilling by the drilling device 3 has been performed normally. In this discrimination means, for example, whether or not the hole is formed is detected using a proximity switch or the like.

  The station ST3 is provided with discrimination means (not shown) for detecting (discriminating) whether or not the assembly by the assembling apparatus 5 has been normally performed. In this discrimination means, for example, whether or not the component is attached is detected by using a proximity switch or the like.

  In the station ST4, a discriminating means (not shown) for detecting (discriminating) whether or not the inspection (measurement of the inner diameter d) by the inspection apparatus 7 has been normally performed or whether the measured value is within an allowable range. Z).

  In addition, each of the stations ST2 to ST4 is provided with a projection unit 19 that projects visible light onto each workpiece W of each of the stations ST2 to ST4 according to the determination result by each of the determination units.

  The projection means 19 is used when the work by each working means (the drilling device 3, the assembling device 5, the inspection device 7) is normally performed and when the work by the working means is always performed illegally. The projector is configured to change the color of the projected light.

  For example, when the work by the working means is normally performed, blue light is continuously projected on almost the entire work W, and when the work by the working means is always performed illegally, Red light is continuously projected on almost the entire work W.

  When the work by the working means is illegally performed, it is desirable to stop the conveyance of the pallet P and the work W by the belt conveyor.

  Note that the light to be projected may be blinked instead of or in addition to changing the color of the light. For example, when the work by the working means is normally performed, blue light is continuously projected onto the work W, and when the work by the working means is always performed illegally, blue or red light is projected. You may project by blinking light. Further, the blinking pattern may be changed.

  In addition, when the work by the working means is normally performed, the light is not projected onto the work W, and when the work by the working means is always performed illegally, the light is projected onto the work W. May be performed.

  The color of the light to be projected is preferably different from the color of the lighting in the factory where the production apparatus 1 is installed.

  In order to improve the visibility of the operator, it is desirable to irradiate light from multiple directions so that almost the entire work W is not shadowed. However, light is projected from one direction to almost the entire work W. May be.

  Furthermore, as long as the visibility of the operator can be maintained in a good state, light may be projected onto a wide area of a part of the work W instead of projecting light onto the entire work W. Moreover, you may make it project light on the wide area | region or pallet P of the whole or a part of production apparatus 1. FIG.

  Further, the production device 1 detects whether or not the work by the working device has been started (whether the operator has pressed the start switch of the production device 1 for a predetermined time while the production device 1 is operable). (Means for detecting whether or not), and in accordance with the detection result by the detection means, the projection means 19 may project visible light onto the workpiece W.

  For example, when the work by the working means is started, the light is not projected onto the work W, and when the work by the working means is not started, the light is projected onto the work W continuously. May be performed. In this case, it is desirable that the light to be projected has a different color from the light to be projected according to the determination result (for example, purple). Furthermore, you may make it project the light of blinking red etc. to the workpiece | work W, when the operation | work by the said operation means is not started.

  According to the production apparatus 1, since the discrimination result by the discrimination means is displayed by projecting visible light onto the work W, whether or not the work on the work W by the work means such as processing of the work W has been normally performed. (The quality of the work) is intuitively given to the operator's visual angle. In other words, the quality of the work W, etc., is communicated to the operator in a state linked directly to the work W. The operator can surely know that the work on the workpiece W has not been performed normally, and the workpiece W which has not been performed normally is prevented from being sent to a subsequent process, and a defective product is generated. It is possible to avoid the risk of being lost.

  In addition, the workpiece W has a certain size (for example, a size that can be placed on the palm of the operator, a size that can be held by the operator's arm, and a size that is almost the same as the operator's body) and is visible. If the size of the part of the workpiece W on which the light is projected is about 10% of the whole workpiece W, the size of the workpiece W is almost equal to the whole, the production apparatus 1 for operating other devices, etc. Even an operator away from the operator can see whether or not the work (working, etc.) on the workpiece W has been normally performed, and the operator can surely know that the normal work by the working means has not been performed. It is possible to prevent a product that has not been subjected to normal work from being sent to a subsequent process, thereby avoiding the possibility of producing a defective product.

  In addition, according to the production apparatus 1, since the color of the light to be projected is changed between when the work is normally performed and when the work is performed illegally, the color sense of the operator As a result, the operator can visually recognize that the work on the workpiece W has not been performed normally, and the operator can more reliably know that the normal operation by the working means has not been performed. .

  In addition, although one hole punching device 3, one assembling device 5, and one inspection device 7 have been described as examples of the working means, a plurality of devices may exist. Furthermore, at least one (for example, only one drilling device 3) may exist.

  In addition to the drilling device 3, the assembly device 5, and the inspection device 7, other types of devices (working means) may be provided. Further, the pallet P may be omitted, or the workpiece W may be placed at a fixed position without performing a conveyor, and the workpiece W may be sequentially subjected to operations such as processing.

  That is, at least one of reflecting the discrimination result by the discrimination means directly on the work W, projecting directly, projecting directly, and attaching directly is performed. In addition, if the operator who is away from the production apparatus 1 can see, the determination result by the determination means may be displayed by a display means of another configuration. .

  That is, an operator who is within a radius of 20 m or within a radius of 30 m from the work W installation site in the production apparatus 1 displays the determination result so as to be visible, or, for example, a predetermined in a factory where the production apparatus 1 is installed. It may be displayed so that an operator in a passage, a work area, or a waiting space of the section (a section in which each production machine handled by the operator is installed) can visually recognize the determination result.

  By the way, in the production method of a product for producing a product or a semi-finished product from a workpiece, the invention described in this specification is a work for processing the workpiece, a work for assembling parts to the work, and a work for inspecting the work. A work process for performing at least one of the above, a determination process for determining whether or not the work by the work process has been normally performed, and projecting visible light to the workpiece according to a determination result by the determination process You may grasp | ascertain as invention of the production method of the product which has a projection process to do.

[Second Embodiment]
FIG. 2 is a plan view showing a schematic configuration of a product production apparatus 51 according to the second embodiment of the present invention.

  In the first embodiment, a product production apparatus (automated line) that automatically conveys workpieces has been described as an example.

  The product production apparatus 51 according to the second embodiment is different from the product production apparatus 1 according to the first embodiment in that the work of the apparatus 51 is carried and carried (conveyed) by the operator of the apparatus 51, and other points. Is configured in substantially the same manner as the product production apparatus 1 according to the first embodiment, and has substantially the same effect.

  The product production apparatus 51 includes, for example, ten stations ST1 to ST10 arranged in a “U” shape. An arrow AR1 shown in FIG. 2 indicates the flow direction of the workpiece. Upstream of each station ST1 to ST10 is a work container for storing a work, and downstream of each station ST1 to ST10 is a finished product container for storing a finished product (for example, a product). Has been.

  Each station ST1 is provided with one or more working means, and each of the other stations ST2 to ST10 is also provided with one or more working means. Therefore, the product production apparatus 51 is provided with a plurality of working means.

  A determining means is provided for each of the working means. That is, a plurality of determination means are provided corresponding to each of the working means. Projection means is also provided for each of the determination means. That is, a plurality of projection means are provided corresponding to each of the determination means.

  As described above, the transfer (conveyance) of the workpiece between the stations ST1 to ST10 is manually performed by, for example, a plurality of operators R1, R2, and R3 of the product production apparatus 51. Operators R1, R2, and R3 carry the workpieces by hand to transfer the workpieces between the stations ST1 to ST10. Each of the operators R1, R2, and R3 is in charge of one or more of the stations ST1 to ST10.

  More specifically, in the product production apparatus 51, the operator R1 is mainly responsible for each station ST1, ST2, ST9, ST10, and the operator R2 is mainly responsible for each station ST3, ST6, ST7, ST8, ST9. The station R3 is mainly in charge of each station ST3, ST4, ST5, ST6. As already understood, a plurality of operators may be in charge of one station. For example, the station ST3 is in charge of the operator who is in contact with one of the two operators R2 and R3.

  In addition, the operator R1 performs work transfer between the stations ST1 and ST2, and one of the operators R1 and R2 performs work transfer between the stations ST2 and ST3. Is being transported.

  In this way, in the product production apparatus 51 that is operating, the operator R1 mainly handles the stations ST1 and ST2 on the upstream side and the stations ST9 and ST10 on the downstream side. For example, the stations ST9 and ST10 After the work (for example, work setting and transfer work) is finished, if the work by the working means at the stations ST1 and ST2 is finished when turning around, the work existing at the station ST2 is directly transferred to the downstream station. There is a possibility that a process skip in the station ST2 (a situation where a defective workpiece not processed at the station is sent to a subsequent station) occurs at the station ST2.

  The process skip may occur in the same way in the operators R2 and R3.

  However, in the product production apparatus 51, since the result of the discrimination means is displayed by the projection means, it is possible to avoid the possibility that each operator R1, R2, R3 skips the process.

  The product production apparatus 51 also includes a plurality of detection means for detecting whether or not work by the respective work means has been started, as in the product production apparatus 1 according to the first embodiment. You may make it project a result by each said projection means.

It is a top view which shows schematic structure of the production apparatus of the product which concerns on the 1st Embodiment of this invention. It is a top view which shows schematic structure of the production apparatus of the product which concerns on the 2nd Embodiment of this invention.
