Description

  The present invention relates to an apparatus for handling a plate-like material to be processed, which can be safely and quickly performed by always keeping the plate-like material to be in a vertical state and minimizing a planar occupation area.

In order to automatically perform a predetermined treatment on a plate-like material in a series of continuous processing steps, the plate-like material is transferred while accurately adjusting and maintaining the predetermined posture and height of the material to be treated in each step. A so-called transfer device for loading, transferring and transporting is essential.
For example, a transfer device that receives a plate-like material to be processed from the previous process, transfers it to each predetermined processing position, performs various processing, and passes it to the subsequent process. (1) A placement unit plane expansion / contraction operation and a lifting / lowering operation for directly transferring a workpiece of a predetermined size to the placement unit with respect to the unloader unit in the previous process and the loader unit in the subsequent process, (2) (3) A precision operation function such as a turning operation, an elevating operation, and a back-and-forth operation for transferring the processing material to the processing position is required.
Handling equipment such as plate-shaped materials such as mother glass (hereinafter referred to as “mother glass” for liquid crystal photomask glass) requires robust, quick and accurate positioning of the mother glass because the mother glass is heavy. Is done.

  Thus, the conventional representative device is provided with a parallel shift link mechanism type lifting device in the center of the base portion of the rail-type transport traveling device via the rotating vertical axis device for turning, and the pantograph on the upper link shaft support member. Attach the rear shaft attachment member of the link type planar longitudinal movement device, and separate the rear portions of the two horizontal arms for horizontally placing the plate-like workpieces on all the shaft attachment members of the expansion / contraction link (pantograph) type planar longitudinal movement device. It is a support-mounted one.

However, conventional plate-type material handling equipment such as mother glass tends to be large due to the above-mentioned needs, and since the mother glass is always handled in a horizontal state, the plane occupation area is wide, and it is quick and accurate. The mother glass is difficult to handle and inefficient, and causes troubles with the front and back processes and nearby equipment.
In other words, the above-described conventional transfer device has a complicated structure in which a parallel shift link mechanism type lifting device provided on a traveling carriage in which a holding guide is slidably mounted on a traveling rail and a rotating vertical axis device for turning on it. Since the height occupying area is large, the lower and lower limit positions of the pair of horizontal arms for mounting are restricted by this and become a high position far away from the traveling floor level, the elevating dead zone is large, and the elevating freedom is narrow.

  The parallel shift link mechanism type lifting device connects the upper and lower main link rods with three horizontal main shafts, and the upper and lower auxiliary link rods parallel to the main link rods are connected to the corresponding upper, middle and lower link shaft support members. Since this is a complex mechanism connected by a single horizontal auxiliary shaft, the amount of buffer deformation with respect to the load when the plate-shaped workpiece is placed on the upper placement horizontal arm is large, and the placement horizontal arm As a result of the forward tilt displacement, the handling weight of the plate-like workpiece is greatly restricted. This is because the same problem occurs even with an expansion / contraction link type plane back-and-forth movement device in which a pair of left and right front and rear link rods are connected by a vertical main shaft for approaching and separating. Etc. are difficult to transfer.

Problems caused by the above structure lead to a decrease in the posture and height adjustment accuracy of the material to be processed due to the transporting operation, turning operation, elevating operation, and back-and-forth operation of the transfer device itself, and accurately setting the predetermined value. And it is difficult to maintain it, and the plate-like material to be processed in a horizontal state is inevitably handled.

Accordingly, the present inventors have developed the plate-like material handling apparatus introduced in Patent Document 1 with the following problems.
(1) In order to minimize the area occupied by the plane, the plate-shaped workpiece is always placed in the vertical state, received from the previous process, accommodated and held in the apparatus, transported, transferred to the intermediate process, and transferred to the next process. The present invention provides a plate-type material handling apparatus that employs a mechanism that enables safe and accurate loading.
(2) In addition, it is possible to accurately grasp the three-dimensional position management of the material to be processed by the transporting operation, turning operation, raising / lowering operation, and back-and-forth operation of the handling device itself, and adjusting the posture and height of the material to be processed. Improving the accuracy of each position control, accurately setting it to a predetermined position and posture value, and maintaining it, enabling the above-mentioned various handling operations of the plate-shaped material to be processed in a very stable and accurate manner.
(3) In addition, the clamping claw mechanism for the plate-shaped workpiece reliably prevents the external scattering of the dust even if it is generated from the main parts of the drive and operation, and prevents the plate-shaped workpiece from being contaminated with dust. Provide a mechanism to prevent.
(4) To further widen the size configuration and weight of the plate-like material to be handled and to secure a wide support area for holding.

  As shown in FIG. 5, the plate-shaped material handling apparatus has a horizontal traveling body HS with a turning post CP, a turning post CP with a horizontal turning arm CA with a rotating elbow EB, and a rotating elbow. An L-shaped eaves frame TF is attached to the tip of the horizontal revolving arm CA by a vertical axis TJ so as to be capable of revolving. The lower part of the long box TB is connected to the lower part of the eaves frame TF along the horizontal axis and The central part of the long box TB is connected to the upper part by a front / rear drive mechanism FB composed of a screw type front / rear drive mechanism SK and a universal connection mechanism UR, and the lower end edge of the plate-like workpiece is attached to the long box TB. And a claw mechanism that supports and releases the upper end edge with the upper and lower clamping claws HT. The clamping claw mechanism has a motor JK1 and a screw JK2 type vertical drive mechanism JK in a long box TB. A pair of upper and lower claw holding rings TR are provided so as to be movable in the longitudinal and longitudinal direction outside the box TB. A clamping claw HT is attached to the front surface of each claw holding ring TR, and the rear part of the claw holding ring TR is placed behind the long box TB. It is inserted into the box TB from the side and connected to the screw JK2 of the vertical drive mechanism JK. Further, an encoder and an electromagnetic brake are attached to each horizontal turning mounting portion of the turning post CP, the horizontal turning arm CA with a rotating elbow, and the saddle frame TF.

  In the basic transfer operation of the plate-shaped workpiece with the above-described configuration, the operator manually operates the operation handle with an operation table provided on the front heel frame TF. By using the encoders provided at the joints at the tip and the above, the transfer operation is performed based on the operation trajectory input in advance, and the safe area that can be operated is registered. In this case, the operation can be stopped by an electromagnetic brake to prevent a collision with other devices.

  On the other hand, delivery to other devices is performed at a predetermined height while the plate-shaped workpiece supported by the clamping claw mechanism using the support stand is kept in a vertical state or inclined obliquely. However, if the mother glass is up to a certain size, the mother glass can be installed on the lower standard without changing the height of the support base, or the apparatus installed on the central standard, or both. Can be delivered to other devices.

However, this plate-like material handling apparatus has the following problems in delivery to the receiving apparatus.
The operation of the long box in the delivery of the plate-shaped workpiece to the receiving device is performed by a front-rear rotation drive coupling mechanism connected to the center of the swinging frame and the back of the long box. In addition to the pattern in which the processing material delivery pattern is changed from the vertical state to the predetermined inclination state, a pattern for changing from the vertical state to the horizontal state is added. Furthermore, in the trend that the size configuration of the plate-like material to be processed is various, there is a limit to the tilting speed of the long box, and it has become difficult to deliver quickly.
In addition, the longitudinal box drive mechanism for the long box that supports the plate-shaped workpiece with the clamping claw mechanism has a complicated structure consisting of a screw-type front-rear drive mechanism and a universal connection mechanism, and has a length that is longer than the center part of the heel frame. Since it always extends between the center of the back of the shank box and the swiveling operation while the long box is tilted and tilted, a moving space for the forward / backward rotation drive coupling mechanism itself is required, which forms a dead zone, etc. Therefore, the non-interference area is narrow and improvement in workability and safety is urgently required. Furthermore, especially when handling thin plate-shaped materials with a large area, vibrations from side to side and back and forth may occur during tilting movements, affecting the quality of the plate-shaped materials and safety issues.

A rotation drive connection mechanism XK for tiltably mounting the long box TB is provided at the lower end of the plate, and the lower end edge and the upper end edge of the plate-like workpiece W are sandwiched and supported by the upper and lower clamping claws HT on the long box TB. The holding claw mechanism KK to be opened is mounted, and the holding claw mechanism KK has a motor screw type vertical drive mechanism similar to that shown in FIG. 5 in the long box TB, and moves in the longitudinal and longitudinal direction outside the long box TB. Possible to hold a pair of left and right nails A pair of upper and lower clamping claws HT are mounted on the front surface of the claw holding ring TR, the rear part of the claw holding ring TR is inserted into the box TB from the rear side of the long box TB, and the insertion part is inserted into the vertical driving mechanism. Connected to the screw. Further, an encoder and an electromagnetic brake are attached to each horizontal turning mounting portion of the turning post CP, the horizontal turning arm CA with a rotating elbow, and the saddle frame TF.

  Thus, the rotation drive connection mechanism XK of the long box TB provided in the kite frame TF is provided on the frame GK constituting the lower part of the kite frame TF, and the long box TB is in an upright state centering on the lower part thereof. To an arbitrary tilting position from horizontal to horizontal.

As shown in detail in FIG. 3, the rotational drive coupling mechanism XK includes the following (1) to (8).
(1) A base shaft rotation support that is rotatably supported in a horizontal state by a bearing member 101 provided at the lower portion of the front portion of the saddle frame TF, and a bearing TBJ provided at the lower portion of the long box TB is rotatably supported. Shaft 100.
(2) The piston shaft 200 that moves back and forth in the rotation direction of the long box TB.
(3) A pair in which one end is fixedly connected to the bearing TBJ of the long box TB and the other end is axially connected to the front portion of the piston shaft 200 so that the longitudinal movement of the piston shaft 200 is changed to the rotational operation of the bearing TBJ. Crank arm 300.
(4) A piston shaft bearing member 400 that rotatably connects the rear portion of the piston shaft 200 with a shaft 401.
(5) Two pairs of guided members 500 mounted on the upper and lower sides of the piston shaft bearing member 400.

(8) A forward / reverse rotation drive device 800 that is installed at a rear fixed position of the frame GK and operates the screw shaft 700 in forward / reverse rotation.

  Thus, the rotation support shaft 100 is a rotation base shaft for tilting the long box TB that supports the entire load of the long box TB but holds the plate-shaped workpiece W with the clamping claws HT. When tilting while holding the treatment material W, the cushion seat 130 provided at the lower portion of the front end portion of the frame GK that holds the bearing 101 is placed in the upper curved peripheral surface KD1 of the load receiving base KD of the load receiving vehicle KUC. It is housed and stably held. The configuration of the cushion seat 130 will be described in detail with reference to FIGS.

4 (1) and (2), the rotary bearing shaft 100 is rotatably supported by bearings 101 provided on both sides of the front end of the frame GK. The cushion seat 130 includes a pair of leg portions 120, a horizontal seat plate 125, spring mechanisms 126 and 127, a curved cushion plate 128, and a limit switch 129. Each leg 120 is an L-shaped member showing a semicircular shape when viewed from the side. The upper both sides are located inside each bearing 101 and the lower part is located directly below the distal end of the frame GK and fixed with fasteners. Although not shown, it is separately fixed and attached to the front end of the frame GK with a sufficiently strong screw.
Reference numerals 121 to 124 shown in the drawing are guides for insertion in the front, rear, left and right of the long box TB main body when the long box TB main body is placed on the load receiving base KD.

A horizontal seat plate 125 is provided between the lower portions of both leg portions 120, and spring mechanisms 126 and 127 are installed on the lower surfaces of the left and right sides of the horizontal seat plate 125. The spring mechanisms 126 and 127 are curved cushion plates. 128 is suspended. When the curved cushion plate 128 is accommodated and placed in the upper curved peripheral surface KD1 of the load receiving base KD, moves slightly upward with the load, and comes into contact with the lower surfaces of both leg portions 130, the long box is received by the landing signals from both limit switches 129. The downward movement of TB is stopped.
The pair of crank arms 300 are transmission links that convert the forward / backward movement of the piston shaft 200 into the rotation / tilt movement of the long box TB. For example, an L-shaped elbow member, a triangular piece member, And a connecting member provided with a connecting portion of a mold).
The crank arm 300 of this example has left and right sides of the rotary bearing shaft 100 in which the upper and lower ¬ type connecting portions 300a and 300b are point-symmetrical and the lower ¬ type connecting portion 300a is fixed to the lower portion of the long box TB. The upper ¬ type connecting portion 300b is fixed to the front portion of the piston shaft 200 for rotating the crank arm and is rotatably mounted on the shaft 301.

The piston shaft 200 has a shaft 301 whose front portion is parallel to the rotary support shaft 100 and rotatably supports the first connecting portion 300b on the pair of crank arms 300 and whose rear portion is parallel to the rotary support shaft 100. The piston shaft bearing member 400 is connected by 401, and moves forward and backward by the rotation of the screw shaft 700 screwed and connected to the lower portion of the piston shaft bearing member 400, thereby stably rotating the pair of crank arms 300.

The piston shaft bearing member 400 is supported by screwing a lower bearing 402 with a screw shaft 700 and supported by two pairs of guide rails 600 via two pairs of guided members 500 in the upper, lower, left, and right directions. Thus, the piston operation of the piston shaft 200 is performed stably.

The two pairs of guided members 500 operate the piston shaft bearing member 400 back and forth while accurately maintaining a horizontal state along the guide rail 600.

The two pairs of guide rails 600 are provided so as to face each other in parallel and horizontally so that the two pairs of guided members 500 can be moved back and forth horizontally without rolling and without shaking.

The screw shaft 700 is in a horizontal state and axially supports the front and rear end portions thereof by bearings 702 and 703, and the body portion is screwed into the bearing 402 of the piston shaft bearing member 400, so The piston shaft bearing member 400 is moved back and forth horizontally by rotational driving.

In the forward / reverse rotation driving device 800, a servo motor 801 is disposed at the upper center of the rear portion, a pulley 803 is mounted on the rotation driving shaft 802, and the pulley 803 rotates to a pulley 701 on the screw shaft 700 side via a timing belt 804. A spring-pressing pulley 805 for transmitting and adjusting the tension of the timing belt 804 is attached.

With the above configuration, the long box TB that holds the plate-like workpiece W in the upright state shown in FIG. 1 uses the small forward rotation drive torque of the forward / reverse rotation drive device 800 in the rotation drive coupling mechanism to drive the screw shaft 700. By rotating the crank arm 300 through 90 degrees through the piston shaft bearing member 400 and the piston shaft 200, the plate-shaped workpiece W together with the long box TB is rotated forward 90 degrees accurately and quickly. Can be leveled.
In addition, since the plate-shaped workpiece W in a horizontal state is transferred only to the long box TB after being transferred to another device or the like, the forward / reverse rotation drive device 800 reverses the screw shaft 700 with a small reverse rotation drive torque. By rotating and rotating the crank arm 300 through 90 degrees through the piston shaft bearing member 400 and the piston shaft 200, the original upright state can be accurately and quickly restored safely.
In the 90-degree rotation of the long box TB, the crank arm 300 during the downward rotation of the long box TB avoids the piston shaft 200 from being in a horizontal state at the start of rotation, and is connected to the piston shaft 200. 301 is positioned on an inclination angle line of 45 degrees rearward with respect to a vertical line passing through the axis of the rotation support shaft 100, and the piston shaft 200 is set upward by 2 to 3 degrees from the horizontal. When the rotation angle position of 301 is 45 degrees, it is positioned on the vertical line to maximize the upward inclination angle of the piston shaft 200, and from here the connecting shaft 301 is on the inclination angle line of 45 degrees forward with respect to the upper vertical line. When placing and stopping, the piston shaft 200 is again turned upward by 2 to 3 degrees from the horizontal, and the long box TB is made horizontal.
As a result, the piston shaft 200 smoothly rotates the support shaft 100 through the crank arm 300 forward and backward by 95 degrees to roll the long box TB from the upright state to the horizontal state, and vice versa. It is rolled upright from the beginning.

In the plate-like material handling apparatus according to the present invention, the longitudinal box drive connection mechanism of the long box that supports the plate-like material by the clamping claw mechanism has the above-mentioned robust and simple structure. The lower end of the long box is supported to be tilted at the center, and the load from the long box is equally received by the pair of crank arms on the left and right. This is received from the front shaft mounting portion of the piston shaft to the rear shaft mounting portion and the piston shaft bearing. A pair of guided members on both sides of the piston shaft bearing member and the screw shaft are equally distributed and supported through the member, and the long box swings left and right and back and forth during tilting and stopping. It is surely prevented.
As a result, the forward / backward rotation drive connection mechanism enables accurate tilting operation and speeding up of the long box, enables quick, accurate and safe delivery to other devices, and enables a wide variety of plate-like covers. Realizes the execution of the ambiguous delivery pattern of processing materials without adversely affecting the quality, and secures a free section between the heel frame and the back of the long box without any dead zone, and other devices. The work area and safety are greatly improved by expanding the interference area.
As a result, the functions that the handling device originally has, that is, ○ Expansion of freedom of plate-like material to be processed such as mother glass, ○ Reduction of buffer deformation amount against load and drastic reduction of handling weight limit, ○ Mounting posture Stable maintenance of ○, the marked posture, height, plane, and position adjustment accuracy of various handling operations are greatly improved, ○ High efficiency, high availability, and safe transport processing functions are stably maintained at a high level. There are many effective uses in the seed industry.
