Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to an apparatus for reading information of a work conveyed by a conveyor.

2. Description of the Related Art Conventionally, in order to sort and select works conveyed by a conveyor, an operator manually reads information such as labels, prints, cards, and markings attached to the works.

However, in the above-mentioned conventional method, the processing ability of the worker is low,
Therefore, if the amount of transported work increases, the processing cannot be completed,
If the work is stagnant or if the worker becomes tired, it may be misread, and it may be dangerous if the work is heavy because manual work is required to find the position of the work information. .

The present invention solves these problems, and an object of the present invention is to provide a work information reading device capable of reading work information quickly and reliably and safely performing these works.

Means for Solving the Problems In order to solve the above problems, a work information reading device of the present invention comprises a roller conveyor for conveying a work, a position sensor for detecting the tip of the work, and a tip for directing the work. It is provided in a tilted "C" shape and pushes up the turning rollers provided at the tips respectively.
A lifting device that lifts and rotates the work on the roller conveyor by these turning rollers, a controller that stops the roller conveyor based on a signal from the position sensor, and drives and controls the lifting device and the turning roller, and the work. The reading means is provided for reading information provided on the outer circumference of the work at a certain distance from the tip.

With the above configuration, when the work is conveyed by the roller conveyor and the position sensor detects the tip of the work and stops the roller conveyor, the position sensor is preliminarily positioned so that the information of the work is located at the position of the reading means. The position of is determined, the conveyor is stopped via the control device based on the signal of the position sensor that detects the tip of the work, and then the turning roller is pushed up by the pushing device,
The work is slightly lifted from the roller conveyor, the turning roller is rotated at the same time, and the information of the work is read by the reading means. When the information of the work is read, the turning roller is stopped, the pushing device is lowered, the work is returned to the roller conveyor, and the work is conveyed again by the roller conveyor. All of these operations are performed via the control device, and a quick, reliable, and safe reading operation can be performed.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view of a work information reading apparatus according to an embodiment of the present invention, and FIG. 2 is a side view of the work information reading apparatus. In FIGS. 1 and 2, reference numeral 1 denotes a roller conveyor, which can convey and stop the work W. When the position sensor 2 detects the front end of the work W, the controller 3
Thus, the roller conveyor 1 is stopped. The rollers 4 of the roller conveyor 1 are formed in a drum shape and are arranged in a direction orthogonal to the workpiece conveying direction, and the workpiece W is conveyed at the position of the depression of the central portion of the rollers 4. Denoted at 5 are lifting devices, which are provided as a pair on the left and right sides in the transport direction of the work W stopped together with the roller conveyor 1 by the detection of the position sensor 2, and the two pairs of the lifting devices 5 are arranged at appropriate intervals in the transport direction. And the lifting device 5 of the pair is the third
As shown in the figure, the respective tips are provided in a “C” shape inclined toward the work W. A turning roller 6 is provided at the tip of each lifting device 5, and when the lifting device 5 pushes up this turning roller 6, the turning roller 6 slightly lifts the work W above the roller conveyor 1, The turning roller 6 that rotates under the control of the control device 3 rotates the work W around the axis. Reference numeral 7 is a reading sensor for reading the information D provided on the outer circumference of the work at a position apart from the tip of the work W by the information D provided on the outer circumference of the work W when the work W stops together with the conveyor 1. It is arranged so as to face the outer peripheral surface including, and is provided so as to face the same angle as the lifting device 5 as shown in FIGS. 3 and 4.

As shown in FIG. 5, the control device 3 inputs a signal from the position sensor 2, controls the roller 4, the lifting device 5, and the turning roller 6 of the roller conveyor 1, and controls the reading sensor 7 to perform the reading operation. Control and read sensor 7
The information of the work W read by is sent to the device of the subsequent process by the cable 8.

The reading sensor 7 is a bar code reader, CCD
A reading means such as a camera or a magnetic card reader can be used.

FIG. 6 is a cross-sectional view showing details of the rollers 4 of the roller conveyor 1, and a roller drive motor 9 for rotating each roller 4.
Is provided inside the roller 4, one end of which is supported by a motor 9 and the other end of which is supported by a bearing. These bearings and the motor shaft of the motor 9 are fixed to a conveyor table 10, and the roller 4 rotates. Driven.

7 and 8 show another embodiment of the conveyor roller. In FIG. 7, the roller driving motor 11 is provided outside each hourglass roller 12, and the roller 12 is rotationally driven by the rotation of the motor shaft. Further, in FIG. 8, each conveyor roller is arranged such that a pair of rollers 13 whose axes are perpendicular to the conveying direction are arranged so that the rollers are in a horizontal row, and the end portions facing each other are lower. The rollers 13 are rotationally driven by the rotation of the motor shafts of the roller driving motors 14 provided outside.

Next, the operation will be described. When the position sensor 2 detects the leading edge of the work W conveyed on the roller conveyor 1, the control device 3 stops the rotation of the roller 4 of the roller conveyor 1, and the lifting device 5 causes the turning roller 6 to move. The work W is pushed up to lift the work W, the turning roller 6 is rotated to rotate the work W, and the information D provided on the outer periphery of the work W is read by the reading sensor 7. At this time, the reading sensor 7 is arranged so as to face the outer peripheral surface including the information D at the stop position of the work W, and is provided so as to face the same angle as the lifting device 5, so that the lifting device 5 has the same configuration. The distance from the outer circumference of the workpiece W to the reading sensor becomes constant during reading, and the focus adjustment of the reading sensor 7 is simple and simple, and the reading is accurate and there is no error.
Then, when the work W rotates and the information D is read, the control device 3 stops the rotation of the turning roller 6, lowers the lifting device 5, returns the work W onto the roller 4 of the roller conveyor 1, and then the roller 4 Is rotated to convey the work W to the next step. At the same time, the read information is converted into a signal necessary for the post-process and transmitted to the post-process by the cable 8.

Effects of the Invention According to the present invention, the information on the outer circumference of the work, which is a certain distance from the tip of the work, can be swiftly and reliably, requires no manual labor, does not cause tiredness or misreading, and involves dangerous work. It is possible to obtain the effect that work can be carried out safely without any.
Further, since the number of working steps is small and the read information can be read quickly and reliably, and the work is not stopped by colliding with a stopper or the like, the work is not shocked or damaged. Further, even if the length and the diameter of the work are different, the information of the work can be read in the same manner.
