In the apparatus for measuring the weight of the main part constituting member of the opening/closing body according to the present invention, as described above, below the conveying means for conveying the main part constituting member of the opening/closing body, there is provided a longitudinal direction of the main part constituting member of the opening/closing body. A plurality of weight sensors for measuring the weight of the main constituent member of the opening/closing body by placing at least two portions thereof are arranged at intervals in the conveying direction of the conveying means. The sensor is lifted and lowered by lifting means. Further, information including at least the length dimension of the opening/closing body main part constituting member is provided at the tip portion of the opening/closing body main part constituting member, and this information is read by the reading means.

Then, the processing means for executing a predetermined process for measuring the weight of the main constituent members of the opening/closing body, before the main constituent members of the opening/closing body are placed on the plurality of weight sensors, Based on the length dimension of the opening/closing body main part constituting member read by the reading means, the lengthwise central portion of the opening/closing body main part constituting member is used to measure the weight of the opening/closing body main part constituting member. From among the plurality of weight sensors, the opening/closing body is positioned to reach the middle point of the distance from the arrangement position of the most forward weight sensor in the conveying direction of the conveying means to the arrangement position of the most rearward weight sensor in the conveying direction of the conveying means. A process of transporting the main constituent members by the transport means is executed.

Thus, when the main constituent member of the opening/closing body is placed on the plurality of weight sensors used for measuring the weight of the main constituent member of the opening/closing body, the main constituent member of the opening/closing body is conveyed by the conveying means. is evenly supported by the frontmost weight sensor in the conveying direction of the conveying means and the rearmost weight sensor in the conveying direction of the conveying means.

Here, when the main constituent member of the opening/closing body is placed on a plurality of weight sensors used for measuring the weight of the main constituent member of the opening/closing body, the main constituent member of the opening/closing body has this Vibration occurs due to the contact of the main constituent members of the opening/closing body with the plurality of weight sensors. Unable to start weighing. If the members constituting the main parts of the opening/closing body are not evenly supported by the forwardmost weight sensor in the conveying direction of the conveying means and the most rearward weight sensor in the conveying direction of the conveying means, then the vibration generated will continue until the generated vibration subsides. , it takes time to start the weight measurement.

However, in the apparatus for measuring the weight of main constituent members of the opening/closing body according to the present invention, as described above, the main constituent members of the opening/closing body are used to measure the weight of the main constituent members of the opening/closing body. When placed on the weight sensors, the opening/closing body main constituent members are evenly supported by the frontmost weight sensor in the conveying direction of the conveying means and the rearmost weight sensor in the conveying direction of the conveying means. It has become.

As a result, vibration of the main constituent member of the opening/closing body caused by placing the main constituent member of the opening/closing body on a plurality of weight sensors used for measuring the weight of the main constituent member of the opening/closing body Since it is possible to shorten the time until the vibration subsides, it is possible to shorten the time until the weight measurement of the main constituent members of the opening/closing body is started.

As described above, in the apparatus for measuring the weight of the main constituent members of the opening/closing body according to the present invention, the work of measuring the weight of the main constituent members of the opening/closing body is carried out by the operator using a general crane device, as in the conventional case. The panel is not measured by lifting the panel at two or multiple points using wires, but it is carried out while it is being conveyed by the conveying means. can be incorporated into one process of the manufacturing line work of the switchgear. In the apparatus for measuring the weight of main constituent members of the opening/closing body according to the present invention, the main constituent members of the opening/closing body are mounted on the plurality of weight sensors used for measuring the weight of the main constituent members of the opening/closing body. It is designed to reduce the time it takes for vibrations generated when placed to subside. In other words, it is possible to shorten the vibration time that occurs when the main constituent member of the opening/closing body is placed on a plurality of weight sensors used for measuring the weight of the main constituent member of the opening/closing body. ing.

Therefore, according to the apparatus for measuring the weight of the main constituent members of the opening/closing body according to the present invention, the work of measuring the weight of the main constituent members of the opening/closing body can be performed easily and quickly.

In the apparatus for measuring the weight of the main part constituting member of the opening/closing body according to the present invention, any method may be used to provide information including at least the length dimension of the main part constituting member of the opening/closing body at the tip of the main part constituting member of the opening/closing body. Alternatively, information including at least the length dimension of the main constituent member of the opening/closing body may be directly printed or stamped on the leading end portion of the main constituent member of the opening/closing body, and at least the length dimension of the main constituent member of the opening/closing body may be printed or stamped. A label printed or stamped with information to be included may be attached to the front end portion of the member constituting the main part of the opening/closing body, and may be arranged so as to be detachable.

In the apparatus for measuring the weight of the main part constituting member of the opening/closing body according to the present invention, the information provided at the tip of the main part constituting member of the opening/closing body includes the length dimension of the main part constituting member of the opening/closing body, as well as the opening/closing weight. Identification information for identifying the main part constituting members of the opening/closing body, identification information for identifying the opening/closing device including the main part constituting members of the opening/closing body, width dimensions of the main part constituting members of the opening/closing body, main parts of the opening/closing body (for example, information on the number of the opening and closing body main part constituting members in the main part from the opening side of the opening and closing body), etc. good.

In the apparatus for measuring the weight of the member constituting the main part of the opening/closing body according to the present invention, the reading means reads the information provided at the tip of the member constituting the main part of the opening/closing body, and includes at least the length dimension of the member constituting the main part of the opening/closing body. Any format or structure may be used as long as it can read information including The reading means may be, for example, an optical character reader (OCR), a barcode reader, or the like.

In the apparatus for measuring the weight of the constituent members of the main parts of the opening/closing body according to the present invention, the plurality of weight sensors arranged below the conveying means are connected to the elevating means when the weight of the main parts constituting the opening/closing body is measured. After the weight of the opening/closing body main constituent members is measured, the lifting means descends to the original height below the conveying means.

In the apparatus for measuring the weight of the main constituent members of the opening and closing body according to the present invention, the reading means may be arranged at any position, but the reading means does not interfere with the main constituent members of the opening and closing body conveyed by the conveying means. Also, it is preferable to place it in a position that does not interfere with the operator.

On the other hand, the information provided at the tip of the member constituting the main part of the opening/closing body may also be placed at any position, but it is preferable to place this information at a position where the reading means can easily read it.

In the apparatus for measuring the weight of the constituent members of the main parts of the opening/closing body according to the present invention, the reading means is fixedly arranged above the central portion in the width direction of the conveying means (in other words, the direction perpendicular to the conveying direction of the conveying device). The information provided at the leading end of the member constituting the main part of the opening/closing body is provided at the center in the width direction (in other words, the direction orthogonal to the conveying direction of the conveying device) of the main constituting member of the opening/closing body at the leading end. In this case, before or during the transportation of the main constituent members of the opening/closing body by the conveying means, the widthwise central position of the main constituent members of the opening/closing body is the widthwise central position of the conveying means, i.e., the reading means. may deviate (in other words, do not match) with the position where is fixedly arranged. In such a case, there is a possibility that the reading means fixedly arranged above the widthwise central portion of the conveying means may not be able to correctly read the information provided at the leading end portion of the member constituting the main portion of the opening/closing body.

For this reason, the main opening/closing body constituent member for making the widthwise center position of the main opening/closing body constituent member conveyed by the conveying means coincide or substantially coincide with the widthwise central position of the conveying means. You may make it provide a width direction center position adjustment means.

Here, the means for adjusting the widthwise central position of the main constituent member of the opening/closing body causes the widthwise central position of the main constituent member of the opening/closing body conveyed by the conveying means to match or substantially coincide with the widthwise central position of the conveying means. Any form or structure may be used as long as it can be used.

In the apparatus for measuring the weight of the main part constituting member of the opening/closing body according to the present invention, as an example of the means for adjusting the center position of the main part constituting the opening/closing body in the width direction, it is arranged on both sides in the width direction of the conveying means on the upper surface of the conveying means, a rod-like member having a length in the conveying direction of the conveying means and movable in the width direction of the conveying means by a driving force from the driving means; movement limit detection means for detecting that each rod-like member moved inward in the width direction of the conveying means reaches a movement limit while the constituent members are being conveyed by the conveying means. I can list what I have.

In this example, when the movement limit detection means detects that each rod-shaped member moved to the inside in the width direction of the conveying means has reached the movement limit, the constituent members of the main parts of the opening/closing body It is sandwiched by the rod-shaped members arranged in the direction of the conveying means, and is in a state of being straight or substantially straight in the conveying direction of the conveying means. It will be in a state of matching or substantially matching.

In addition, the movement limit detection means (in other words, movement limit detection sensor) is arbitrary as long as it can detect that each rod-shaped member moved inward in the width direction of the conveying means reaches the movement limit. Any form or structure may be used. In other words, the movement limit detecting means may be of any type as long as it can detect that each bar-shaped member moved inward in the width direction of the conveying means has come into contact with the member constituting the main part of the opening/closing body. It can be structural. For example, the movement limit detection means may be a microswitch, a tape switch, or the like, which is provided on the inner surface side of each rod-shaped member and is operated when each rod-shaped member comes into contact with the opening/closing body main part constituent member.

Here, the number of movement limit detection means provided on the inner side surface of each bar member is arbitrary, but the widthwise central position of the main constituent member of the opening/closing body coincides or substantially coincides with the widthwise central position of the conveying means. In order to detect this more accurately, it is preferable to provide a plurality of movement limit detection means at predetermined intervals in the transport direction of the transport means on the inner surface side of each rod-like member. In this case, when all the movement detecting means provided on the inner side surface of each rod-like member are actuated, the widthwise center position of the main constituent member of the opening/closing body coincides with or substantially coincides with the widthwise center position of the conveying means. It should be determined that they match.

When the movement limit detecting means detects that each rod-shaped member moved inward in the width direction of the conveying means has reached the movement limit, the processing means detects that each rod-shaped member is driven by the driving force from the driving means. After stopping the movement of the conveying means to the inner side in the width direction, each rod-shaped member is moved to the original position before the movement (in other words, the initial position) by the driving force from the driving means to the outer side in the width direction of the conveying means. Execute the process to move.

Each rod-shaped member may consist of one rod-shaped member, or may consist of a plurality of rod-shaped members.

In addition, in the example of the means for adjusting the width direction central position of the members constituting the main parts of the opening and closing body described above, it is stated that "when the main parts constituting the opening and closing body are being conveyed by the conveying means," The movement to the inner side in the width direction includes not only the movement of the main constituent members of the opening/closing body during conveyance, but also the time when the main constituent members of the opening/closing body being conveyed are temporarily stopped at a predetermined position.

In the apparatus for measuring the weight of the main constituent members of the opening and closing body according to the present invention, when the number of weight sensors is at least three, the weight sensors used for measuring the weight of the main constituent members of the opening and closing body are: The number may be two, or three or more (in other words, at least three).

In the latter case, the at least three weight sensors used for measuring the weight of the opening/closing body main part constituent members are the most forward weight sensor in the conveying direction, the most rearward weight sensor in the conveying direction, and It may be at least one weight sensor arranged between two weight sensors.

According to this, when the main constituent member of the opening/closing body is placed on at least three weight sensors, it is evenly supported by the most forward weight sensor in the conveying direction and the most rearward weight sensor in the conveying direction. In addition, it will also be supported by at least one weight sensor located between these two weight sensors. For this reason, compared to the case where two weight sensors are used to measure the weight of the main constituent member of the opening/closing body, the main constituent member of the opening/closing body is Since it is possible to shorten the time until the vibration of the main constituent members of the opening/closing body subsides due to being placed on the multiple weight sensors used to measure the weight, weight measurement can be started accordingly. It will be possible to shorten the time until

In the apparatus for measuring the weight of main constituent members of the opening/closing body according to the present invention, when measuring the weight of the main constituent members of the opening/closing body, the main constituent members of the opening/closing body are placed directly on the upper surfaces of the plurality of weight sensors. Alternatively, a flat bar having a length in the width direction of the conveying means may be arranged on the upper surface of each of the plurality of weight sensors, and the main constituent members of the opening/closing body are placed on the upper surface of these flat bars. You may do so.

According to the latter case, compared with the former case, when measuring the weight of the main constituent member of the opening/closing body, the main constituent member of the opening/closing body is more stably supported by the plurality of flat bars, At this time, it is possible to minimize the vibration generated in the constituent members of the main parts of the opening/closing body.

In the apparatus for measuring the weight of the main constituent members of the opening/closing body according to the present invention, the conveying means may be of any type and structure as long as it can convey the main constituent members of the opening/closing body.

A first example of the conveying means is a roller conveyer having a large number of rollers arranged at predetermined intervals in the conveying direction and rotating these rollers by driving force from a driving means. In this first example, each of the plurality of weight sensors may be arranged below between rollers adjacent to each other so as to be vertically movable by means of a lifting means.

A second example of the conveying means is a belt conveyor having a plurality of conveying belts arranged at predetermined intervals in the direction orthogonal to the conveying direction (in other words, the width direction of the conveying means). In this second example, each of the plurality of weight sensors may be arranged below between adjacent conveyor belts so as to be vertically movable by means of a lifting means.

In the apparatus for measuring the weight of the member constituting the main part of the opening/closing body according to the present invention, the information provided at the tip of the member constituting the main part of the opening/closing body may be only character information. Only the information represented by , or both of these information may be used.

In the apparatus for measuring the weight of the main constituent member of the opening/closing body according to the present invention, the weight sensor may be of any type and structure as long as it can measure the weight of the main constituent member of the opening/closing body. The weight sensor may be a mechanical weight sensor using a spring and a lever, or an electric weight sensor such as a strain gauge type, metal gauge type, or semiconductor gauge type.

In the apparatus for measuring the weight of the members constituting the main parts of the opening and closing body according to the present invention, when the number of weight sensors is four, the positional relationship of these weight sensors is arbitrary. If the distance from the sensor placement position to the placement position of the second weight sensor in the transport direction is L, the distance from the placement position of the second weight sensor in the transport direction to the placement position of the third weight sensor in the transport direction is , and L, and the distance from the placement position of the third weight sensor in the transport direction to the placement position of the fourth weight sensor in the transport direction may be three times L.

Note that the positional relationship of these weight sensors when the number of weight sensors is three is arbitrary. If the distance from the placement position to the placement position of the second weight sensor in the transport direction is L, the distance from the placement position of the second weight sensor in the transport direction to the placement position of the third weight sensor in the transport direction is L. may be doubled.

When the number of weight sensors is three or more, the weight sensor used for measuring the weight of the main constituent member of the opening/closing body is the information provided at the tip of the main constituent member of the opening/closing body. (dimension in the conveying direction of the conveying means). All weight sensors may be used regardless.

In the former case, for example, when the number of weight sensors is four, the length dimension of the main constituent member of the opening/closing body to be weight-measured is the weight from the first weight sensor to the third weight sensor in the conveying direction. If the distance is less than the distance to the sensor, the first and second weight sensors in the conveying direction are used, and the length dimension of the main constituent member of the opening/closing body to be weight-measured is the first in the conveying direction. If the distance from the weight sensor to the third weight sensor is greater than or equal to the distance from the first weight sensor to the fourth weight sensor in the conveying direction and less than the distance from the first weight sensor to the fourth weight sensor in the conveying direction, the first and third weight sensors in the conveying direction Alternatively, the 1st, 2nd, and 3rd weight sensors in the conveying direction are used, and the length dimension of the main constituent member of the opening/closing body to be weight-measured is the 4th weight from the 1st weight sensor in the conveying direction. If it is greater than the distance to the sensor, the 1st and 4th weight sensors in the transport direction, or the 1st, 2nd and 4th weight sensors in the transport direction, or the 1st, 3rd and 4th weight sensors in the transport direction, or , 1st, 2nd, 3rd, and 4th weight sensors in the conveying direction (in other words, all weight sensors) may be used. In the latter case, there is a weight sensor on which the members constituting the main parts of the opening/closing body are not placed.

Incidentally, in this embodiment, the hinge 3 , the bar member 4 and the guide roller 5 described above are related members related to the shutter curtain 1 . Furthermore, a locking device (not shown) is also a related member related to the shutter curtain 1 .

A rotating shaft 7 is horizontally arranged above the entrance, and two winding drums 10 are attached to both axial ends of the rotating shaft 7, which is rotatably supported by brackets 8 and 9. A driving string-like member 11 made of a wire or the like whose upper end is connected to the winding drum 10 is wound around the winding drum 10 so as to be unreeled. It is connected to the lower end of the curtain 1 . A rotating member 12 such as a sprocket wheel is integrally connected to one of the two winding drums 10, and an interlocking endless string-like member such as a chain is wound around the rotating member 12. 13 is also hung around the rotating member 14 . Since a rotating member 15 such as a pulley around which an operating endless string member 16 is wound is integrally connected to the rotating member 14, a person operates the operating endless string member 16 to rotate the rotating member. 15 is rotated forward and backward, and this rotation is transmitted to the rotating member 14, the interlocking endless string member 13, and the rotating member 12, and when the winding drum 10 and the rotating shaft 7 rotate forward and backward, the winding drum 10 is driven. The shutter curtain 1 is guided by the guide rail 6 and moved to open and close by winding and unwinding the cord-like member 11 .

One end of is connected to a bracket 8 which is a stationary member, and the other end is connected to a rotating shaft 7 . When the return spring 20 wound around the outer circumference of the rotary shaft 7 is wound tightly in this manner, the return spring force is accumulated in the return spring 20, so that, for example, as shown in FIG. As described above, when the shutter curtain 1 reaches the fully closed position, the operation of rotating the rotating shaft 7 by manipulating the operating endless string member 16 to open and move the shutter curtain 1 upward is performed by this rotation. Rotation of the shaft 7 is assisted by the return spring force of the return spring 20 .

When a person operates the operating endless string-like member 16 in the opposite manner to the above-described operation, the shutter curtain 1, which has moved upward to open, moves downward to close. , the shutter curtain 1 rotates in the opposite direction to that when the shutter curtain 1 is moved to open, so that the return spring force is accumulated in the return spring 20 again.

The rotating shaft 7 shown in FIG. 1 is composed of two left and right rotating shaft members 7A and 7B connected by a joint member 17. These rotating shaft members 7A and 7B are attached to brackets 8 and 9, respectively. A winding drum 10 and a return spring 20 are arranged on each of the rotating shaft members 7A and 7B.

Thus, in the present embodiment, the return spring force is accumulated in the return spring 20 when the shutter curtain 1, which can be freely opened and closed, is moved to close, and the accumulated return spring force is used for the opening movement of the shutter curtain 1. The specification of this return spring 20 is determined by the return spring for an oversliding door device, which is a specification determining device for a return spring for an opening/closing device according to an embodiment of the present invention, which will be described later. is determined by the specification determination device of

Therefore, the widthwise central position M3 (see FIG. 3) of the panel 2 being conveyed by the roller conveyor 22 coincides or substantially coincides with the widthwise central position M4 (see FIG. 3) of the roller conveyor 22. preferable. However, as shown in FIG. 3, the widthwise center position M3 of the panel 2 may not coincide with the widthwise center position M4 of the roller conveyor 22 before or during the transport of the panel 2. can occur.

If such a case occurs, the camera 34 fixedly arranged above the width direction center position M4 of the roller conveyor 22 will read the two-dimensional code information 32F of the information label 32 arranged at the front end portion 2A of the panel 2. It may not be read correctly.

Therefore, in consideration of such a case, in the present embodiment, the roller conveyor 22 is set so that the widthwise center position M3 of the panel 2 being conveyed by the roller conveyor 22 is positioned at the widthwise center position of the roller conveyor 22. Panel width direction center position adjustment means 37 shown in FIGS. there is

The structure of the panel width direction central position adjusting means 37 will be described below with reference to FIG. 9 and FIG. 10 which is a partial enlarged view of the central portion of FIG. 9 and 10, illustration of the rollers 24 of the roller conveyor 22 is omitted. Further, in FIG. 10, for the convenience of explaining the structure of the panel width direction central position adjusting means 37, a part of the rod-like member 38 is shown broken away.

As shown in FIG. 9, the panel width direction central position adjusting means 37 according to this embodiment are arranged on both sides of the roller conveyor 22 in the width direction on the upper surface of the roller conveyor 22, and the roller conveyor 22 is conveyed. , and is movable in the width direction of the roller conveyor 22 (the arrow direction in FIG. 9) by the driving force from the driving means 41; When the panel 2 is being conveyed by the roller conveyor 22, each bar member 38 moved inward in the width direction of the roller conveyor 22 contacts the panel 2 and reaches the movement limit. and a movement limit detection means that does not move.

As shown in FIG. 10, the drive means 41 comprising an electric motor and a brake for driving the two rod-shaped members 38 is provided by two installation members installed on the left and right side frames 25 of the roller conveyor 22. It is placed on a plate-shaped base member 40 coupled to the upper surface of 39 .

Next, a mechanism for moving the two rod-like members 38 inward or outward in the width direction of the roller conveyor 22 by the driving force from the driving means 41 will be described.

As shown in FIG. 10, the rotational force of the drive shaft (not shown) of the drive means 41 whose axial direction is the conveying direction of the roller conveyor 22 is transmitted by the power transmission means 43 to the length of the roller conveyor 22 in the conveying direction. is transmitted to a rod-shaped driven shaft 42 (see also FIG. 9). The power transmission means 43 comprises a pulley 44 on the drive shaft side of the driving means 41, a pulley 45 on the driven shaft 42 side, and an endless belt 46 wound around these pulleys 44 and 45. As shown in FIG. The driven shaft 42 is received by bearing members 48 placed on a plurality of installation members 47 installed on the left and right side frames 25 of the roller conveyor 22 .

The rotational force of the driven shaft 42 is transmitted by the power transmission means 50 to the rotating shaft 49 whose axial direction is the conveying direction of the roller conveyor 22 . The power transmission means 50 comprises a pulley 51 on the driven shaft 42 side, a pulley 52 on the rotary shaft 49 side, and an endless belt 53 wound around these pulleys 51 and 52 .

A portion of the rotating shaft 49 opposite to the pulley 52 side is a miter bevel gear (not shown). A miter gear (not shown) meshes with the rotating shaft 49, and the rotational force of the rotating shaft 49 is transmitted to the rotating shaft 54 having the miter gear.

Further, the rotational force of this rotating shaft 54 is transmitted by power transmission means 55 to a rod-shaped rotating member 56 whose axial direction is the width direction. The power transmission means 55 comprises a pulley 57 on the rotating shaft 54 side, a pulley 58 on the rotating member 56 side, and an endless belt 59 wound around these pulleys 57 and 58 .

A left (right) screw groove 60 is formed on the surface of the rotating member 56 from near one end 56A to near the center, and on the surface from near the other end 56B to near the center of the rotating member 56. A right (left) screw groove 61 is formed in the .

Both ends 56A and 56B of the rotating member 56 are received by bearing members 62 and 63 fixed to the left and right side frames 25 of the frame 23 of the roller conveyor 22. , 63 in the longitudinal direction of the rotary member 56, that is, the portions where the left and right screw grooves 60, 61 are formed, nut members 64, 65 are screwed.

The nut member 64 is connected by a connecting member 66 to the rod-shaped member 38A on the side of the power transmission means 55, and the nut member 65 is connected by a connecting member 67 to the rod-shaped member 38B on the side opposite to the power transmission means 55. there is

As can be seen from the above description, when the drive shaft (not shown) of the electric motor of the drive means 41 rotates forward, the forward rotational force (in other words, driving force) of this drive shaft is transmitted through the three power transmission means 43, 50, 55 is transmitted to a rod-shaped rotating member 56 having thread grooves 60 and 61 formed therein.

As the rotating member 56 rotates forward, the rod member 38A, which is connected to the nut member 64 via the connecting member 66, moves (in other words, slides) inward in the width direction of the roller conveyor 22. The rod-like member 38B connected to the nut member 65 via the connecting member 67 is also moved inward in the width direction of the roller conveyor 22 . The movement of the rod-shaped members 38A and 38B is performed by guiding the connecting members 66 and 67 to the guide rails 68 installed on the left and right side frames 25 of the roller conveyor 22. As shown in FIG.

On the other hand, when the drive shaft (not shown) of the electric motor of the drive means 41 rotates in the reverse direction, the rotating member 56 also rotates in the reverse direction, and the bar members 38A and 38B move outward in the width direction of the roller conveyor 22.

Incidentally, as shown in FIG. 9, the power transmission means 50 and 55, the rotating member 56, the nut members 64 and 65, the connecting members 66 and 67, and the guide rail 68 are arranged in the conveying direction of the roller conveyor 22. The two rod-shaped members 38 having a length in the conveying direction of the roller conveyor 22 are movable in the conveying direction inwardly and outwardly.

In the present embodiment, as described above, when the panel 2 is being conveyed by the roller conveyor 22, each rod-shaped member 38 moved inward in the width direction of the roller conveyor 22 contacts the panel 2 to limit the movement. A movement limit detection means (not shown) for detecting that the end point has been reached is provided on the inner side surface of each rod-shaped member 38 . In the present embodiment, the movement limit detecting means is a pressing type sensor such as a microswitch or a tape switch that is activated when each bar member 38 comes into contact with the panel 2 .

In this embodiment, in order to more accurately detect that the widthwise central position M3 of the panel 2 coincides with or substantially coincides with the widthwise central position M4 of the roller conveyor 22, the movement limit detecting means includes the rod-like members 38 on the inner surface side of the roller conveyor 22 are provided at predetermined intervals in the conveying direction of the roller conveyor 22, and when all the movement detection means provided on the inner surface side of each bar member 38 are actuated, the panel 2 coincides or substantially coincides with the widthwise central position M4 of the roller conveyor 22 . At this time, the panel 2 is sandwiched between the two rod-shaped members 38 and is in a state of being straight or substantially straight in the conveying direction of the roller conveyor 22, and the central position M3 in the width direction of the panel 2 is positioned on the roller conveyor 22. coincides or substantially coincides with the widthwise central position M4 of the conveying means.

In this manner, the two rod-shaped members 38 serve as pressing members for pressing the panel 2 from both sides in the width direction of the panel 2 .

Next, the operation of the panel weight measuring device 21 according to the present embodiment will be described. FIG. 11 is a flow chart showing the flow of control processing (except the first step S1) executed by the processing means 71 shown in FIG. , and FIG. 12 is a flow chart showing the continuation of the flow of control processing shown in FIG.

In this embodiment, the work of measuring the weight of the panel 2 by the weight measuring device 21 is incorporated into one process of the manufacturing line work of the oversliding door device. The operation of placing the panel 2 for which the (manufacturing operation of the panel 2, etc.) has been completed on the roller conveyor 22 for weight measurement is carried out (step S1).

Next, when the operator operates a start button of an operation device (not shown) provided in the weight measuring device 21, the processing means 71 executes processing for starting driving means (not shown) of the roller conveyor 22. , the roller conveyor 22 starts to be driven (step S2). As a result, the panel 2 is conveyed in the conveying direction of the roller conveyer 22 (direction of arrow B shown in FIG. 2) by the rollers 24 rotated by the driving force from the driving means.

After the transportation of the panel 2 is started, the processing means 71 determines whether the panel position sensor 36 has been activated, that is, whether the infrared rays transmitted from the light transmitting section 36A of the panel position sensor 36 to the light receiving section 36B are detected during transportation. A process for judging whether or not the front end portion 2A of the panel 2 has interrupted is executed (step S3). In this step S3, when the processing means 71 determines that the panel position sensor 36 is not operating (step S3-NO), the determination processing in this step S3 is repeated, and the panel 2 is continued to be transported.

On the other hand, when the processing means 71 determines in step S3 that the panel position sensor 36 has been activated (step S3-YES), the processing means 71 executes a process of stopping the drive means of the roller conveyor 22. Accordingly, the driving of the roller conveyor 22 is stopped (step S4). Therefore, as shown in FIG. 13, the panel 2 stops at a position slightly advanced in the transport direction from the position where the panel position sensor 36 is arranged. That is, the panel 2 is positioned at a position where the two-dimensional code information 32F of the information label 32 arranged at the front end portion 2A of the panel 2 can be read by the camera 34 of the two-dimensional code reader 33 (see FIG. 4). Stop.

In the present embodiment, as shown in FIG. 3, the panel 2 is moved while the widthwise center position M3 of the panel 2 being conveyed does not match or substantially matches the widthwise center position M4 of the roller conveyor 22. 13, and in such a case, the camera 34 of the two-dimensional code reader 33 detects the two-dimensional image of the information label 32 located at the leading edge 2A of the panel 2. There is a possibility that the code information 32F cannot be read. Therefore, in this embodiment, the width direction center position M3 of the stopped panel 2 is adjusted to the width direction center position M4 of the roller conveyor 22 by the panel width direction center position adjusting means 37 (see FIGS. 3 and 4). A matching or near-matching process is performed.

After step S<b>4 described above, the processing means 71 executes processing for driving the driving means 41 of the panel width direction central position adjusting means 37 . As a result, the left and right rod-shaped members 38 arranged on both sides in the width direction of the panel 2 are electrically moved to the inner side in the width direction of the panel 2 (in other words, the inner side in the width direction of the roller conveyor 22) by the driving force of the driving means 41. is started (step S5).

After the left and right rod-shaped members 38 have started to move, the processing means 71 determines whether the left and right rod-shaped members 38 have come into contact with the side surfaces of the panel 2 and reached the movement limit. A process for determining whether or not all of the movement limit detection means (not shown) provided in the above-mentioned are operated by coming into contact with the side surface of the panel 2 is executed (step S6). In this step S6, when the processing means 71 determines that all the movement limit detection means are not operating (step S6-NO), the determination process of this step S6 is repeated, and the movement of the left and right rod-like members 38 continues. be done.

On the other hand, in step S6, when the processing means 71 determines that all of the movement limit detection means have been operated (step S6-YES), the processing means 71 causes the driving means 41 of the panel width direction center position adjusting means 37 to be driven. Execute the process to stop. As a result, the left and right rod-like members 38 stop moving electrically (step S7).

After step S7, the processing means 71 causes the two-dimensional code reader 33 to read the two-dimensional code information 32F of the information label 32 arranged on the front end portion (in other words, the front portion) 2A of the panel 2. Then, a process to set the image is executed (step S8).

As described above, the image of the two-dimensional code information 32F of the information label 32 photographed by the camera 34 of the two-dimensional code reader 33 shown in FIG. It is processed by image processing means having an AD converter and a decoder. Thereafter, the information of the control number 32A and the length dimension 32B of the panel 2 is obtained from the two-dimensional code information 32F by the processing means 71 (step S9).

In this embodiment, the total number of strain gauge load cells 26 is four as shown in FIGS. 2, 3 and 7, and the length of the panel 2 shown in FIG. Dimension L is greater than the distance (L1+L2) from the first strain gauge load cell 26A from the right to the third strain gauge load cell 26C shown in FIG. to the fourth strain gauge type load cell 26D (L1+L2+L3).

Therefore, in this embodiment, among the four strain gauge load cells 26A to 26D shown in FIGS. The strain gauge type load cells 26 used to measure the weight of are three from the first to third from the right shown in FIG. 13 (in other words, three forward in the conveying direction of the roller conveyor 22) strain gauge type load cells 26A to 26C.

That is, in this embodiment, the strain gauge load cell 26 used for measuring the weight of the panel 2 is selected from among the four strain gauge load cells 26A to 26D according to the length dimension of the panel 2. Only the two forward strain gauge load cells 26A, 26B in the conveying direction, or only the three forward strain gauge load cells 26A-26C in the conveying direction, or all four strain gauge load cells 26A-26D.

For this reason, before the panel 2 is placed on the three strain gauge load cells 26A-26C used to measure the weight of the panel 2, the stationary panel 2 shown in FIG. The longitudinal central portion M1 is the most forward in the conveying direction from the first strain gauge load cell 26A from the right to the third most rearward strain gauge load cell 26C from the right in the conveying direction. The panel 2 must be transported (in other words, moved) forward by the roller conveyor 22 until it reaches the midpoint M2 (see FIG. 14) of the distance to the position.

For this purpose, first, after step S9, the processing means 71 calculates the distance to move the stopped panel 2 forward in FIG. (step S10).

After this step S10, the processing means 71 executes a process for starting the driving of the driving means (not shown) of the roller conveyor 22, and thus the driving of the roller conveyor 22 is started (step S11). As a result, the panel 2 starts moving forward in the conveying direction of the roller conveyor 22 .

After the panel 2 starts moving again, the processing means 71 executes a process of determining whether or not the panel 2 has moved forward by the predetermined distance calculated in step S10 (step S12). Whether or not the panel 2 has moved a predetermined distance can be determined by, for example, if the drive means of the roller conveyor 22 is an electric motor, whether or not the drive shaft of the electric motor has rotated a predetermined number of times. .

In this step S12, when the processing means 71 determines that the panel 2 has not moved forward by the predetermined distance (step S12-NO), the determination processing in this step S12 is repeated, and the movement of the panel 2 is continued. .

On the other hand, in step S12, when the processing means 71 determines that the panel 2 has moved forward by a predetermined distance (step S12-YES), the processing means 71 executes a process of stopping the drive means of the roller conveyor 22. (step S13). This stops the forward movement of the panel 2 . FIG. 14 is a diagram showing this time. As shown in FIG. 14, the front end portion 2A of the panel 2 has moved from the position shown in FIG. 13 to a position spaced a distance L4 forward from the first strain gauge load cell 26A from the right. It will be. At this time, the position of the rear end portion 2B of the panel 2 is a distance L4 behind the third strain gauge type load cell 26C from the right.

After step S13, the processing means 71 executes processing for starting to raise the piston rod 28 of the air cylinder 27 (step S14).

After the piston rod 28 of the air cylinder 27 starts to rise, the processing means 71 determines whether the piston rod 28 has risen by a predetermined amount (that is, whether the height position of the upper surface of the piston rod 28 has changed from the position shown in FIG. 14 to the figure). 15) is executed (step S15).

In this step S15, when the processing means 71 determines that the piston rod 28 has not risen by the predetermined amount (step S15-NO), the determination processing of this step S15 is repeated, and the piston rod 28 continues to rise.
