When the workpiece 3 follows the roller 102 to be transported along the length direction of the transfer rack and its end contacts the gear bar 104 in the width direction of the transfer rack 101, it indicates that the workpiece 3 has been transported to the position and can be weighed.

[0031] In the middle and lower part of the length direction of the transport frame 1, there is a space for placing the weighing module 2. The weighing module 2 is arranged below the transport frame 1, including a base 205, and a lifter 204 is arranged above the base 205. The lifter 204 is arranged in an H-shaped structure, and its transmission mechanism is a bevel gear ball screw structure. The lifter 204 is fixed on the base 205 and driven by a motor 206 also fixed on the base 205. There are four lifters 204, which are arranged at the four corners of the base 205 respectively.

[0033] refer to Figure 1 The support 201 includes a base and support brackets arranged at intervals on the base. The multiple support brackets are arranged in parallel. When located below the transfer rack, the support brackets can protrude upward from the hollow table of the transfer rack under the action of the lifter 204 from below the transfer rack, and are arranged at intervals with the rollers 102 arranged on the hollow table. That is, the support brackets can protrude upward from the space between the rollers 102, thereby supporting the workpiece 3.

[0034] Two cylinders 103 are arranged at the long side guard of the transfer frame body 101. The cylinder stroke is greater than the length of the roller 102.

The transfer rack body 101 is provided with a sensor, such as an infrared sensor or a gravity sensor. When a workpiece is detected to be transported, the controller starts the drive motor to drive the roller to rotate, and the rotation of the roller further drives the workpiece to move.

[0039] When the moving workpiece is conveyed to a position against the shift rod 104 , the pressure sensor on the shift rod 104 sends a signal to the controller, and the controller controls the driving motor to stop rotating.

[0040] The controller sends a signal to the motor 206 of the weighing module 2, and the motor 206 rotates, driving the screw system to rise. The four lifters 204 rotate synchronously and at the same speed, driving the support frame 203 of the electronic scale 202 and the top support 201 located on the support frame 203 to rise. The supporting support of the top support 201 protrudes upward from the space between the rollers 102, thereby supporting the workpiece 3.

[0041] When the workpiece is completely separated from the roller and is completely supported on the support, the controller controls the motor to stop the lifting action.

[0042] The electronic scale records the weighing value at this time and sends the value to the controller.

[0043] The controller records the workpiece mark and the weighing value. After recording, the controller sends a signal to the motor 206 of the weighing module 2, and the motor 206 rotates, driving the screw system to descend until the support bracket of the top bracket 201 is retracted downward from the space between the rollers 102, until it is located below the rollers and does not block the rollers and the workpiece on the rollers. The controller controls the motor to stop rotating.

[0044] The controller controls the cylinder 103 to move, and the cylinder rod of the cylinder 103 extends to push the workpiece 3 toward the slide rail until it abuts against the stop rod at the end of the slide rail.

[0045] The controller controls the cylinder rod to reset.

[0046] Repeat the above steps to weigh the next workpiece.
