Description

Technical Field

[0001] The present application relates to the field of workpiece clamping technology, and in particular to a clamping device. Background Art

[0002] The clamping device has the advantages of improving production efficiency and ensuring product quality, and plays an important role in mechanical processing, automated assembly, and industrial production sites.

[0003] In the existing production line, in order to achieve good clamping of the workpiece, a clamping mechanism with a connecting rod structure is designed, which controls the motor through a controller to drive the first connecting rod and the second connecting rod to move, so that the clamping arms fixed to the first connecting rod and the second connecting rod are moved closer to or away from each other, thereby achieving clamping of the workpiece transported by the conveying device of the production line.

[0004] However, in actual applications, when the first connecting rod and the second connecting rod are driven by the motor to rotate, the first connecting rod and the second connecting rod can only move 0° to 180° (less than 180°) along the output shaft of the motor. For example, when the output shaft of the motor rotates clockwise to the extreme position, the first connecting rod and the second connecting rod respectively drive the connecting arms closer to each other, and when the two sets of connecting arms need to move in the opposite direction, the output shaft of the motor needs to be controlled to rotate counterclockwise to achieve the reversing operation. This process requires the motor to be stopped before reversing. There is a downtime idle period, which is not conducive to improving the clamping efficiency of the clamping device and needs further improvement. Utility Model Content

[0005] In order to improve the clamping efficiency of the clamping device, the present application provides a clamping device.

[0006] The present application provides a clamping device that adopts the following technical solution:

[0007] A clamping device comprises a carrier, a driving assembly, a tensioning assembly and two groups of clamping mechanisms, wherein the driving assembly is arranged on the carrier, and the two groups of clamping mechanisms are respectively slidably arranged on the carrier along the length direction of the carrier, and the driving assembly is used to drive the two groups of clamping mechanisms to move closer to or away from each other along the carrier to achieve clamping or release of the workpiece, the driving assembly comprises a cam and a driving motor, the driving motor is arranged on the carrier, the cam is coaxially fixed with the driving motor, the driving motor is used to drive the cam to rotate along the carrier, the cam is rotatably carried on the carrier between the two groups of clamping mechanisms, the tensioning assembly is connected to the two groups of clamping mechanisms and the cam, when the cam rotates along the carrier and the two ends of the cam abut against the two groups of clamping mechanisms, the cam pushes the two groups of clamping mechanisms to move in the opposite direction along the carrier, and when the cam rotates along the carrier and the two ends of the cam are separated from the two groups of clamping mechanisms, the tensioning assembly pulls the two groups of clamping mechanisms to move closer to each other along the carrier.

[0008] By adopting the above technical scheme, the cam is driven by the driving motor to rotate along the carrier, and when the two ends of the cam are respectively in contact with the two groups of clamping mechanisms, the cam will push the two groups of clamping mechanisms to move away from each other along the carrier, so as to achieve the purpose of releasing the clamped workpiece; when the two ends of the cam begin to separate from the two groups of clamping mechanisms, the two groups of clamping mechanisms are driven to move towards each other along the carrier through the tensioning assembly, so as to achieve the purpose of clamping the workpiece; compared with the clamping mechanism of the connecting rod structure, the driving motor in the clamping device of the present application does not need to be stopped for reversing, and the cooperation of the driving motor housing cam and the tensioning assembly can realize the orderly and non-stop movement of the two groups of clamping mechanisms towards or away from each other, which plays a positive guiding role in improving the clamping efficiency of the clamping device.

[0009] Preferably, the tensioning assembly includes a first tension spring and a second tension spring, the fixed ends of the first tension spring and the second tension spring are respectively connected to the two groups of the clamping mechanisms, and the free ends of the first tension spring and the second tension spring are respectively coaxially movably connected to the cam; when the two ends of the cam are respectively in contact with the two groups of the clamping mechanisms, the first tension spring and the second tension spring are in a stretched state, and when the two ends of the cam are respectively separated from the two groups of the clamping mechanisms, the first tension spring and the second tension spring gradually contract.

[0010] By adopting the above technical solution, since the free ends of the first tension spring and the second tension spring are respectively coaxially movably connected with the cam, the first tension spring and the second tension spring are in a movably connected state along the cam, reducing the probability of the first tension spring and the second tension spring being wound along the cam. When the two ends of the cam are respectively in contact with the two groups of clamping mechanisms, the first tension spring and the second tension spring are in a stretched state. When the two ends of the cam are respectively separated from the two groups of clamping mechanisms, the first tension spring and the second tension spring shrink rapidly. Since the fixed ends of the first tension spring and the second tension spring are respectively connected with the two groups of clamping mechanisms, the two groups of clamping mechanisms are driven to move closer to each other along the carrier, and the tension provided by the first tension spring and the second tension spring is used to provide power for the two groups of clamping mechanisms to move closer to each other along the carrier.

[0011] Preferably, the clamping mechanism includes a sliding assembly, a clamping arm and a power transmission rod, the sliding assembly is slidably arranged on the supporting frame, the clamping arm is detachably arranged on the sliding assembly, and the spatial position relationship between the clamping arm and the sliding assembly is vertical, the fixed end of the power transmission rod is connected to the sliding assembly, and the free end of the power transmission rod is provided with a rotating bearing, the rotating bearing is rotatably connected to the power transmission rod, and when the cam rotates, the rotating bearing can abut against both ends of the cam.

[0012] By adopting the above technical solution, the clamping arm and the power transmission rod are slid along the length direction of the support frame through the sliding assembly. When the cam rotates to abut against the rotating bearing, the rotating bearing provides rolling friction for the cam, thereby reducing the resistance of the cam pushing the sliding assembly to move along the support frame. At the same time, it also reduces the irreversible mechanical wear of the cam and / or the power transmission rod caused by the hard contact between the cam and the power transmission rod, thereby playing a positive guiding role in increasing the service life of the cam and / or the power transmission rod.

[0013] Preferably, a fixing assembly is provided on the cam, and the fixing assembly includes a first fixing block and a second fixing block, the first fixing block is coaxially fixed to the cam, the second fixing block is provided with fixing holes in a matrix at the corners, the first fixing block and the second fixing block are detachably connected, and when the second fixing block covers the first fixing block, the contour formed between the first fixing block and the first fixing block is adapted to the contour of the output shaft of the drive motor.

[0014] By adopting the above technical solution, through the cooperation of the first fixing block and the second fixing hole, the cam drive motor can be quickly disassembled or installed, so as to facilitate the maintenance or replacement of the drive motor and / or the ridge.

[0015] Preferably, the sliding assembly includes a mounting plate, a sliding guide rail and a slider, the clamping arm is arranged on the mounting plate, the sliding guide rail is arranged on the carrier frame along the length direction of the carrier frame, the slider is arranged on the surface of the mounting plate facing the carrier frame, and the slider slides in cooperation with the sliding guide rail.

[0016] By adopting the above technical solution, the cooperation between the sliding guide rail and the slider helps to reduce the resistance encountered by the mounting plate bearing clamping arm when sliding along the bearing frame, thereby reducing the occurrence of jamming.

[0017] Preferably, the mounting plate is provided with a waist-shaped groove along the length direction, and the clamping arm is fixed to the mounting plate by bolts through the waist-shaped groove.

[0018] By adopting the above technical solution, the installation position of the clamping arm along the length direction of the mounting plate can be adjusted through the waist-shaped groove, thereby indirectly realizing the adjustment of the initial distance and the limit distance between the two sets of clamping arms to meet the clamping requirements of workpieces of different sizes.

[0019] Preferably, the clamping arm includes a connecting portion and a clamping plate, one end of the connecting portion is arranged on the mounting plate, the clamping plate is connected to the other end of the connecting portion, and the spatial position relationship between the clamping plate and the connecting portion is vertical, the clamping plate and the connecting portion are detachably connected, and adjusting wheels are arranged at both ends of the clamping plate along the length direction, the adjusting wheels are rotatably connected to the clamping plate, and the adjusting wheels are used to adjust the placement angle of the workpiece.

[0020] By adopting the above technical scheme, the clamping plate and the connecting part can be detachably connected to facilitate the replacement of clamping plates of different lengths to meet the clamping requirements of workpieces of different lengths and improve the stability of the clamping plate when clamping the workpiece. At the same time, in the process of the clamping plate clamping the workpiece, the adjusting wheel will first contact the workpiece. Since the adjusting wheel is rotatably connected to the clamping plate, the adjusting wheel and the workpiece are rolled together to correct the position of the workpiece, thereby reducing the probability of damage to the clamping device or damage to the workpiece caused by the clamping plate directly clamping the workpiece that is not in the correct position due to deviation in the placement of the workpiece.

[0021] Preferably, it also includes a detection component, which includes a detection sensor and an identification plate. The identification plate is arranged on the mounting plate, and the detection sensor is arranged on the side wall of the carrier frame. When the mounting plate slides along the carrier frame, the identification plate can pass along the detection end of the detection sensor, and the detection sensor is electrically connected to the controller.

[0022] By adopting the above technical solution, through the detection function of the detection sensor, when the clamping plate completes the clamping of the current workpiece, the controller can issue a control instruction to the conveying device of the production line, so that the conveying device transports the next workpiece to be processed to the bottom of the clamping plate of the clamping device, thereby reducing the number of idle operations of the clamping device and improving the clamping fault tolerance rate of the clamping device.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Compared with the clamping mechanism of the connecting rod structure, the driving motor in the clamping device of the present application does not need to stop for reversing.

[0025] 2. The tension provided by the first tension spring and the second tension spring is used to provide power for the two sets of clamping mechanisms to move closer to each other along the carrier. At the same time, since the first tension spring and the second tension spring are in an active connection state along the cam, the probability of the first tension spring and the second tension spring being wound along the cam is reduced;

[0026] 3. The installation position of the clamping arm along the length direction of the mounting plate can be adjusted through the waist groove, thereby indirectly realizing the adjustment of the initial distance and limit distance between the two sets of clamping arms to meet the clamping requirements of workpieces of different sizes.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The present application embodiment discloses a clamping device 1. Figure 1-Figure 3 A clamping device 1 includes a carrier frame 2, a driving component 3, a tensioning component 4 and two groups of clamping mechanisms 5. The driving component 3 is arranged on the carrier frame 2. The two groups of clamping mechanisms 5 are respectively slidably arranged on the carrier frame 2 along the length direction of the carrier frame 2. The driving component 3 is used to drive the two groups of clamping mechanisms 5 to move closer to or away from each other along the carrier frame 2 to achieve clamping or release of the workpiece.

[0034] Furthermore, the driving assembly 3 includes a cam 31 and a driving motor 32. The driving motor 32 is arranged on the supporting frame 2. The cam 31 is coaxially fixed with the output shaft of the driving motor 32. The driving motor 32 is used to drive the cam 31 to rotate along the supporting frame 2. The cam 31 is rotated and supported on the supporting frame 2 between the two groups of clamping mechanisms 5. The tensioning assembly 4 is connected to the two groups of clamping mechanisms 5 and the cam 31. When the driving motor 32 drives the cam 31 to rotate along the supporting frame 2, the cam 31 pushes the two groups of clamping mechanisms 5 to move away from each other along the supporting frame 2. When the two ends of the cam 31 are separated from the two groups of clamping mechanisms 5, the tensioning assembly 4 pulls the two groups of clamping mechanisms 5 to move toward each other along the supporting frame 2.

[0035] Correspondingly, a fixing assembly 7 is provided on the cam 31, and the fixing assembly 7 includes a first fixing block 71 and a second fixing block 72. The first fixing block 71 is coaxially fixed to the cam 31, and the second fixing block 72 has fixing holes in a matrix at the corners. The first fixing block 71 and the second fixing holes are detachably connected; when the second fixing block 72 covers the first fixing block 71, the contour formed between the first fixing block 71 and the first fixing block 71 is adapted to the contour of the output shaft of the drive motor 32.

[0036] Therefore, when it is necessary to fix the cam 31 and the output shaft of the drive motor 32 coaxially, the first fixing block 71 can be first fitted to the side wall of the output shaft of the drive motor 32, and then the second fixing block 72 can be covered on the first fixing block 71. At this time, the output shaft of the drive motor 32 is covered by the first fixing block 71 and the second fixing block 72. Then, the first fixing block 71 and the second fixing block 72 can be locked by bolts, so that the output shaft of the drive motor 32 is stably connected to the cam 31, reducing the swing of the cam 31 when following the rotation of the output shaft of the drive motor 32, and playing a positive guiding role in improving the stability of the drive motor 32 during operation.

[0037] At the same time, through the cooperation between the first fixing block 71 and the second fixing hole, the cam 31 can be quickly disassembled or installed along the drive motor 32, so as to facilitate the maintenance or replacement of the drive motor 32 and / or the ridge.

[0038] The implementation principle of a clamping device 1 in an embodiment of the present application is as follows: the cam 31 is driven by a driving motor 32 to rotate in a directional and non-stop manner along the carrier 2. When the two ends of the cam 31 are respectively in contact with the two groups of clamping mechanisms 5, the cam 31 will push the two groups of clamping mechanisms 5 to move away from each other along the carrier 2, thereby achieving the purpose of releasing the clamped workpiece; when the two ends of the cam 31 begin to separate from the two groups of clamping mechanisms 5, the two groups of clamping mechanisms 5 are driven by the tensioning assembly 4 to move toward each other along the carrier 2, thereby achieving the purpose of clamping the workpiece; compared with the clamping mechanism of the connecting rod structure, the driving motor 32 in the clamping device 1 of the present application does not need to be stopped for reversing. The cooperation of the driving motor 32 shell cam 31 and the tensioning assembly 4 can realize the orderly and non-stop movement of the two groups of clamping mechanisms 5 toward or away from each other, thereby playing a positive guiding role in improving the clamping efficiency of the clamping device 1.

[0039] Reference Figure 1 and Figure 2 The tensioning assembly 4 includes a first tension spring 41 and a second tension spring 42. The fixed ends of the first tension spring 41 and the second tension spring 42 are respectively connected to the two groups of clamping mechanisms 5. The free ends of the first tension spring 41 and the second tension spring 42 are respectively coaxially movably connected to the cam 31. When the two ends of the cam 31 are respectively in contact with the two groups of clamping mechanisms 5, the first tension spring 41 and the second tension spring 42 are in a stretched state. When the two ends of the cam 31 are respectively separated from the two groups of clamping mechanisms 5, the first tension spring 41 and the second tension spring 42 components contract.

[0040] Specifically, a connecting shaft 311 is provided on the cam 31, and the connecting shaft 311 is coaxially formed with the cam 31 in the vertical direction to reduce the probability of the connecting shaft 311 falling off along the cam 31. At the same time, the free ends of the first tension spring 41 and the second tension spring 42 are respectively hung on the connecting shaft 311 through hooks. The installation method here can be: the first tension spring 41 is located above the second tension spring 42, or the second tension spring 42 is located above the first tension spring 41, so as to reduce the mutual interference between the first tension spring 41 and the second tension spring 42 during operation. At the same time, the advantage of the first tension spring 41 and the second tension spring 42 being hung on the connecting shaft 311 through the hook is that as the working time of the first tension spring 41 and the second tension spring 42 increases, the stiffness coefficient of the first tension spring 41 and / or the second tension spring will produce irreversible mechanical damage, and the hook connection is conducive to the operator to quickly replace the first tension spring 41 and / or the second tension spring 42.

[0041] Therefore, since the free ends of the first tension spring 41 and the second tension spring 42 are coaxially and movably connected to the cam 31, the first tension spring 41 and the second tension spring 42 are in a movably connected state along the cam 31, reducing the probability of the first tension spring 41 and the second tension spring 42 being wound along the cam 31. When the two ends of the cam 31 are respectively in contact with the two groups of clamping mechanisms 5, the first tension spring 41 and the second tension spring 42 are in a stretched state. When the two ends of the cam 31 are respectively separated from the two groups of clamping mechanisms 5, the first tension spring 41 and the second tension spring 42 shrink rapidly. Since the fixed ends of the first tension spring 41 and the second tension spring 42 are respectively connected to the two groups of clamping mechanisms 5, the two groups of clamping mechanisms 5 are driven to move closer to each other along the carrier 2. The tension provided by the first tension spring 41 and the second tension spring 42 provides power for the two groups of clamping mechanisms 5 to move closer to each other along the carrier 2.

[0042] It should be noted that since the components and installation methods of the two groups of clamping mechanisms 5 are the same, the difference is that the two groups of clamping mechanisms 5 are symmetrically installed on the support frame 2 about the output shaft of the driving motor 32, and move closer to or away from each other along the support frame 2. In order to facilitate the detailed description of the two groups of clamping mechanisms 5, any one of them will be described in detail below.

[0043] Reference Figure 1 and Figure 2 The clamping mechanism 5 includes a sliding assembly 51, a clamping arm 52 and a power transmission rod 53. The sliding assembly 51 is slidably arranged on the carrier frame 2. The clamping arm 52 is detachably arranged on the sliding assembly 51, and the spatial position relationship between the clamping arm 52 and the sliding assembly 51 is vertical. The free end of the power transmission rod 53 is provided with a rotating bearing 6, and the rotating bearing 6 is rotatably connected to the power transmission rod 53. When the cam 31 rotates, the rotating bearing 6 can abut against both ends of the cam 31.

[0044] Specifically, the sliding assembly 51 includes a mounting plate 511, a sliding guide rail 512 and a slider. The clamping arm 52 is arranged on the mounting plate 511, the sliding guide rail 512 is arranged on the carrier frame 2 along the length direction of the carrier frame 2, and the slider is arranged on the surface of the mounting plate 511 facing the carrier frame 2, and the slider slides in cooperation with the sliding guide rail 512.

[0045] Correspondingly, a positioning groove 11 is provided along the length direction of the carrier 2, and the positioning groove 11 is located on one side of the output shaft of the driving motor 32. The width of the positioning groove 11 is adapted to the width of the sliding guide rail 512. The operator can use the guiding effect of the positioning groove 11 to quickly install the sliding guide rail 512 on the carrier 2 to reduce the situation in which the sliding guide rail 512 is offset during the installation process, causing uneven force applied to the workpiece when the clamping arm 52 clamps the workpiece, resulting in damage to the workpiece. At the same time, the cooperation between the sliding guide rail 512 and the slider helps to reduce the resistance encountered by the mounting plate 511 when the clamping arm 52 slides along the carrier 2, thereby reducing the occurrence of jamming.

[0046] Furthermore, a waist-shaped groove 8 is opened on the mounting plate 511 along the length direction, and the clamping arm 52 is fixed to the mounting plate 511 by bolts through the waist-shaped groove 8. The installation position of the clamping arm 52 along the length direction of the mounting plate 511 can be adjusted through the waist-shaped groove 8, thereby indirectly realizing the adjustment of the initial distance and the limit distance between the two groups of clamping arms 52 to meet the clamping requirements of workpieces of different sizes.

[0047] On the other hand, the external contour of the power transmission rod 53 is set in a rectangular shape and is fixed to the mounting plate 511 by bolts. When the power transmission rod 53 is installed on the mounting plate 511, the power transmission rod 53 and the mounting plate 511 are set in the same direction. At this time, the free end of the power transmission rod 53 faces one end of the cam 31.

[0048] At the same time, a mounting hole is opened at the free end of the power transmission rod 53 along the thickness direction, and a support shaft 12 is installed in the mounting hole. The support shaft 12 can be fixed to the power transmission rod 53 by a nut or a method of cooperating with the mounting hole thread. The rotating bearing 6 is over-fitted with the support shaft 12, so that the rotating bearing 6 is stably installed on the support shaft 12. When the cam 31 rotates to abut against the rotating bearing 6, the rotating bearing 6 provides rolling friction for the cam 31, thereby reducing the resistance of the cam 31 when pushing the sliding assembly 51 to move along the carrier frame 2. At the same time, it also reduces the irreversible mechanical wear of the cam 31 and / or the power transmission rod 53 caused by the hard contact between the cam 31 and the power transmission rod 53, thereby playing a positive guiding role in improving the service life of the cam 31 and / or the power transmission rod 53.

[0049] Reference Figure 1 and Figure 2The clamping arm 52 includes a connecting portion 521 and a clamping plate 522. One end of the connecting portion 521 is arranged on the mounting plate 511, and the clamping plate 522 is connected to the other end of the connecting portion 521. The spatial position relationship between the clamping plate 522 and the connecting portion 521 is vertical. The clamping plate 522 and the connecting portion 521 are detachably connected. Adjusting wheels 9 are arranged at both ends of the clamping plate 522 along the length direction. The adjusting wheel 9 is rotatably connected to the clamping plate 522, and the adjusting wheel 9 is used to adjust the placement angle of the workpiece.

[0050] Specifically, the mounting plate 511 is provided with a limiting groove 13 along the length direction, and the limiting groove 13 is located on one side of the fixed end of the power transmission rod 53. The width of the limiting groove 13 is adapted to the width of the connecting part 521. The installation position of the connecting part 521 is limited by the limiting groove 13. Therefore, when the bolts in the waist-shaped groove 8 are loosened, the connecting part 521 can be adjusted along the limiting groove 13, so that it can adapt to the clamping requirements of workpieces of different sizes.

[0051] At the same time, the clamping plate 522 and the connecting part 521 can be detachably connected by bolts, so as to facilitate the replacement of the clamping plates 522 of different lengths to meet the clamping requirements of workpieces of different lengths and improve the stability of the clamping plate 522 when clamping the workpiece. At the same time, in the process of the clamping plate 522 clamping the workpiece, the adjusting wheel 9 will first contact the workpiece. Since the adjusting wheel 9 is rotationally connected to the clamping plate 522, the adjusting wheel 9 and the workpiece are rolled together, so as to correct the deviation of the workpiece placement position, reduce the probability of the clamping plate 522 directly clamping the workpiece that is not in the correct position due to the deviation of the workpiece placement position, resulting in damage to the clamping device 1, or damage to the workpiece.

[0052] Reference Figure 1 and Figure 2 , also includes a detection component 10, the detection component 10 includes a detection sensor 101 and an identification plate 102, the identification plate 102 is arranged on the mounting plate 511, the detection sensor 101 is arranged on the side wall of the carrier frame 2, when the mounting plate 511 slides along the carrier frame 2, the identification plate 102 can pass along the detection end of the detection sensor 101, and the detection sensor 101 is electrically connected to the controller.

[0053] Specifically, the controller is an existing controller of the production line, which may be a PLC (Programmable Logic Controller) with programming capabilities and a human-computer interaction interface, which will not be described in detail here.

[0054] Furthermore, through the detection function of the detection sensor 101, when the clamping plate 522 completes the clamping of the current workpiece, the controller can send a control instruction to the conveying device of the production line, so that the conveying device transports the next workpiece to be processed to the bottom of the clamping plate 522 of the clamping device 1, thereby reducing the number of empty operations of the clamping device 1 and improving the clamping fault tolerance rate of the clamping device 1.

[0055] Combined with the following application scenarios for explanation: Figure 4 For example, first, the clamping device 1 is installed on a moving device. The moving device described here can be a device with the ability to move in the vertical direction to achieve the purpose of carrying the clamping device 1 to move in the vertical direction.

[0056] The transmission device includes a first transmission component 14 and a second transmission component 15. The first transmission component is arranged in the horizontal direction, and the second transmission component 15 is slidably arranged on the first transmission component 14 along the length of the first transmission component 14. Now, the clamping plates 522 of the two sets of clamping mechanisms 5 are required to cooperate to clamp the workpiece on the first transmission component 14 to the top of the second transmission component 15. The controller controls the first transmission component 14 to transport the workpiece to the bottom of the clamping device 1, and controls the second transmission component 15 to move away from the clamping device 1 in the horizontal direction. Then, the controller controls the drive motor 32 to start working to complete the clamping of the current workpiece. When the identification plate 102 and the detection sensor 101 cooperate with each other, the detection sensor 101 receives the signal reflected by the identification plate 102, indicating that the workpiece has been clamped. At this time, the controller can send control instructions to the first transmission component 14 and the second transmission component 15. At this time, the first transmission component 14 transports the next workpiece to the bottom of the clamping device 1 again. At the same time, the second transmission component 15 moves to the bottom of the clamping device 1 to receive the workpiece clamped by the clamping device 1.

[0057] Through the detection function of the detection sensor 101, when the clamping plate 522 completes the clamping of the current workpiece, the controller can send a control instruction to the conveying device of the production line, so that the conveying device transports the next workpiece to be processed to the bottom of the clamping plate 522 of the clamping device 1, thereby reducing the number of idle operations of the clamping device 1 and improving the clamping fault tolerance rate of the clamping device 1.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
