Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an apparatus for reading information on a workpiece conveyed by a conveyor.

Conventional technology In the past, in order to sort and sort workpieces transported by a conveyor, workers had to manually decipher information such as labels, prints, cards, and engravings attached to the workpieces. .

Problems that the invention aims to solve However, in the conventional method described above, the processing capacity of the worker is low, so when the amount of workpieces transported increases, it cannot be processed completely, and the workpieces become stagnant or the worker becomes fatigued. When searching for the location of information on a workpiece, if the weight of the workpiece is heavy, it may be dangerous.

The present invention is intended to solve these problems, and aims to provide a workpiece information reading device that can quickly and reliably read workpiece information and allow these operations to be performed safely.

Means for Solving the Problems In order to solve the above problems, the present invention conveys the workpiece using rollers arranged at a predetermined angle with respect to the workpiece conveyance direction, and at the same time conveys the workpiece around the axis along the workpiece conveyance direction. A roller conveyor is provided that rotates the workpiece, and a plurality of reading means are arranged along the workpiece conveyance direction, and information attached to the outer circumference of the workpiece is read by one of these reading means. It is.

Effect With the above configuration, the workpieces conveyed by the roller conveyor are simultaneously rotated around the axis.
The information provided at a predetermined position on the outer periphery of the workpiece crosses a position facing one of the plurality of reading means, so that the information on the workpiece can be reliably read.

Embodiment An embodiment of the present invention will be described below based on the drawings.

FIG. 1 is a plan view of a workpiece information reading bag holder according to an embodiment of the present invention, and FIG. 2 is a plan view of the workpiece information reading device. In Figures 1 and 2,
Reference numeral 1 denotes an information reading device, which is disposed between the transport conveyor 2 and the sorting conveyor 3. The rollers 5 for conveying the workpieces are arranged on roller stands 6 arranged in the workpiece conveyance direction, and on the base 4 between these roller stands 6, a plurality of rollers 5 are arranged along the workpiece conveyance direction at predetermined intervals. The rollers 5 on both roller stands 6 are arranged so as to face in the same direction at a predetermined angle with respect to the workpiece conveyance direction, and are opposed to each other between the roller stands 6. The rollers 5 are arranged in pairs, and as shown in FIG. 3, the rollers 5 in the pair are arranged in a V-shape such that the rollers 5 are inclined so that the rollers are lower toward the opposing ends, and Each of the rollers 5 rotates in the same direction, and the workpiece W placed in the valley between the pair of rollers 5 is conveyed in the direction of its axis, and is forcibly rotated around its axis. Further, a motor 8 for driving each roller 5 is provided inside the roller 5, and one end of the roller 5 is provided by the motor 8, and the other end is supported by a bearing. The shaft is fixed to a roller stand 6 via a support 9, and the roller 5 is rotationally driven. Furthermore, depending on the size of the work W, the roller 5
Since the position where the outer surface of is in contact with the workpiece W changes,
The rollers 5 are moved toward and away from each other on a roller stand 6 via a support 9 in order to be adjustable so that the pair of rollers 5 arranged in a V-shape can contact the workpiece 5 on substantially the same conveyance surface. It is configured to be able to slide in any direction, and is fixed once the position is determined.

Information D (for example, a bar code) is provided at a predetermined position on the outer circumference of the workpiece W, and is read by one of the plurality of reading sensors 7 arranged in the workpiece conveyance direction. As shown in FIG. 5, the control device 10 is inputted with a signal read by one of the reading sensors 7, and this information is sent via a cable 11 to a subsequent device. At this time, the angle and inclination of the roller 5 are determined so that it can be read by any one of the plurality of reading sensors 7, and the rotational speed of the roller 5 is set at such a speed that the work does not stagnate due to the amount of work. It is determined to the extent that information D can be read quickly.

In addition, the reading sensor is barcode soda,
Reading means such as CCD cameras and magnetic card readers can be used.

Next, its operation will be explained. The work W transported by the transport conveyor 2 is carried into the valley between the rollers 5 on both roller stands 6, and
The material is conveyed in the axial direction while being forcibly rotated around the axial center by the rotation of the rollers 5. At this time, as the work W rotates, the information D also rotates, so that the information D is reliably read when the work W faces one of the reading sensors 7 arranged in the transport direction during the transport of the work W. be read. The work W that has been completely read is carried out to the sorting conveyor 3 and sent to the next process, and at the same time, the control device 10 sends the read signal through the cable 11 of the next process device.

6 and 7 are a plan view and a side view showing another embodiment of the present invention. Figures 6 and 7
In the figure, a drum-shaped roller 13 is placed on the roller stand 12.
are arranged horizontally at a predetermined angle with respect to the workpiece transport direction, and a plurality of reading sensors 14 are arranged at predetermined intervals along the workpiece transport direction. As shown in the figure, it is placed in the recess in the center of the drum-shaped roller 13 and rotated at the same time as it is transported, and the information D is read by one of the plurality of reading sensors 14. The motor 15 is provided inside the drum-shaped roller 13, as shown in FIG.
3 is supported by a motor 15 at one end and by a bearing at the other end, and these bearings and the motor 15
a The motor shaft is connected to the roller stand 12 via the support 16.
The drum-shaped roller 13 is driven to rotate.
In this embodiment, the drum-shaped roller 13 can be installed horizontally, and the number of rollers can be halved compared to the previous embodiment, which has the effect of simplifying the structure.

In both of these embodiments, the rollers each have a built-in motor, but the same effect can be achieved by driving one or two motors using a transmission device such as a belt, chain, or gear. .

FIG. 10 shows still another embodiment, in which the motor 1
7 is provided outside the roller 18 and supports 19
The roller 18 is fixed to the roller stand 20 via a motor shaft, and the roller 18 is rotationally driven by a motor shaft. The base of the support 19 is rotatably attached to the roller stand 20 around a pin 21, and a long hole 22 as shown in FIG. The mounting position can be adjusted by fitting. In this case, the ratio between the rotation of the workpiece and the amount of transport can be changed. Further, this structure can also be applied to the roller 5 shown in FIGS. 1 to 3.

Effects of the Invention As described above, according to the present invention, since the workpiece is conveyed and rotated by the rollers at the same time, the information on the workpiece can be read continuously and quickly by the reading means. Further, by simply passing the workpiece, information can be reliably read by any one of the plurality of reading means, no matter where the information is located on the outer periphery of the workpiece. In addition, the workpieces are automatically transported and rotated, and no human intervention is required, so work can be carried out safely.
