The present invention relates to a conveying apparatus for processing an object, the object, for example, to automatically transfer the object in order to interpret the information (bar codes, letters, etc.) contained in the mail or bank slips to obtain information of the corresponding area and After the extraction of specific information, the present invention relates to a transfer device for determining whether or not an error of the extracted information or processing, and an automatic processing method of the object using the same.

Prior to the development of the automatic processor, mail and bank slips have been processed by the operator after checking and determining the relevant matters. However, with the development of an automatic processor and the development of OCR (Optical Character Reader) technology for a particular character, its work efficiency has been greatly improved.

On the other hand, the image acquired for the character and barcode recognizer is a very important factor in the processing result. In order to obtain a clearer and clearer image of the object, the distance between the object and the recognizer must be kept constant. It should not be skewed against any baseline.

Hereinafter, a transfer apparatus according to the prior art will be described.

First, Korean Patent Publication (98-014445, November 25, 1998) relates to a flat twin belt feeder that rotates in a reverse direction to each other, and uses a sprocket, an unmanned gear, a gear, a pulley, and the like to simply feed an object. There is a belt and a paper conveying belt, and the object is placed on the main conveying belt, and the paper conveying belt is covered thereon to drive both belts so that the object is conveyed. However, in transporting the excavated black, iron, aggregate, and the like to have a high feed rate, it is merely a configuration for simply transferring the object.

As another prior art, Korean Patent (99-024490, 99.10.5) relates to a transfer device, in which a guide rail is continuously mounted on an upper surface of a table in a lead frame and a circuit board manufacturing process of a semiconductor package, and an upper side thereof. A plurality of rollers are provided to support both sides of the product to be supplied to the product. The sprocket is mounted on both sides of the table and is provided with a guide rail, a pair of chains, a plurality of crossbars, and a bracket extending below the crossbar. To prevent the lower side of the damage and to extend the life of the mesh belt.

In another conventional art, in the sorting process of large-sized postal items, flat mails are inserted one by one, and a belt system is introduced to prevent damage, thereby improving the function of the inserting part, the aligning part, and the conveying part so that accurate and fast processing is possible. ("Back to basic on flats feeding", George Rabindran et al., 5, 1992, united states postal service advanced technology conference).

Recently, a technique of moving an object using a belt to recognize numeric information, converting the recognized information into a barcode, etc., reading it by a barcode reader, and sending it to the corresponding compartment has been proposed. The distance between the laser scanner and the laser scanner is not constant, thereby affecting the state of the acquired information, and it is difficult to obtain information normally, so that an error may occur in the analysis.

As described above, there is a problem in the prior art to accurately transport mails and similar objects, there is a limit to verify the information contained in the object and obtain the best image of the object.

The present invention has been made to solve the above-mentioned problems of the prior art, in the case of transferring the object when the thickness of the object is different easily insert the object and the support roller to move up and down according to the thickness of the inserted object The object of the present invention is to provide a transfer device suitable for acquiring the best information and a method for automatically processing an object using the same, so that the distance between the surface of the object and the tip of the barcode reader or the character recognizer which acquires the image is always constant.

In addition, the present invention is equipped with a guide for a variety of width of the object to be able to easily adjust the position of the guide according to the width of the object to be in a straight line with respect to the direction of travel of the object and the transfer device that can accurately transfer the object Another object is to provide a method for automatically processing an object.

According to the present invention configured as described above, the transfer apparatus for automatic processing according to the thickness of the object is a distance between the front end of the character recognizer 400b and the printer 500 and the object surface at a constant distance to scan a barcode or recognize a character. Since the interval between the "A" is changed according to the thickness of the object when the object is inserted, the driving rollers (200a, 200b, 200c) is fixed so as not to move up and down and the support rollers (300a, 300b, 300c) Since it can be moved up and down by the action of the spring 301 installed on the roller shaft, the distance between the front end of the character recognizer 400b and the printer 500 and the surface of the object 11 regardless of the change in thickness is always maintained Can be.

In addition, in order to secure a constant speed of the object, the diameters of the driving rollers 200a, 200b, and 200c and the pulleys (not shown) connected to the roller shafts are the same, and each shaft is connected by a belt so that the power is constant. The object 11 may be a small mail, a large mail, a printed bar code or a letter such as a bank slip.

4 is a conceptual view of the overall operation of the automatic processing transport apparatus according to an embodiment of the present invention, when the power is supplied to initialize the controller 801 to control the overall operation of the device, and load the object into the supply container of the system The driving rollers 200a, 200b, and 200c are driven by setting the environment and driving the first and second motors M1 and M2 through the motor controller 802. Then, the object 11 supplied from the supply container is detected using the sensors S1 to S5 for each transport section, and the character recognizer 400b, the barcode reader 400a, the printer 500 and the result according to each situation. The display device 600 is operated and the processing result is transmitted to the computer 804 via the processing result transmitter 803. Here, reference numeral 805 denotes a detection signal input / output processor (Input / 0putput processor) of the sensors S1 to S5, and reference numeral 806 denotes an input / output processor (I / O processor) of the controller.

5 is an operation flowchart of an automatic processing transfer apparatus according to the present invention. First, the system environment of the transfer apparatus is set, and when the object 11 is loaded in the supply container, the controller 801 transmits a driving start command to the motor controller. By driving the first motor (M1) through the supply of the object (11) in a sheet from the supply, at this time to drive the first motor (M1) and at the same time set the timer of the first sensor (S1) (S1 to S4).

Subsequently, it is determined whether the first sensor S1 detects the arrival signal of the object 11 (S5). When the determination result is detected, the first sensor S1 transmits the arrival information to the controller 801 and the controller 801. While driving the second motor (M2) and at the same time to set the timer of the second sensor (S2) (S6), at this time, the first driving roller (200a) is operated to move the object (11). Here, in order to secure a constant speed of the object, the diameters of the pulleys connected to the first driving roller 200a and the roller shafts were all the same, and each shaft was connected to the belt so that power was constantly transmitted.

On the other hand, when the determination result that the first sensor (S1) does not detect the arrival signal of the object 11, by comparing the timer value of the set first sensor (S1) (S7), it is determined whether or not within the time (S8) ). Subsequently, as a result of determining whether it is within the time, if the time is within, it generates a message that 'the supply container is empty' (S9), shuts down the system by stopping the first motor (M1) (S10), the object in the supply container After the loading, the arrival of the object is continuously detected.

Subsequently, it is determined whether the second sensor S2 detects the arrival of the object 11 transported by the first driving roller 200a (S11). When the arrival of the object is detected, the second motor ( M1) is stopped (S12). On the other hand, if the second sensor (S2) does not detect the arrival of the object 101, by comparing the timer value of the set second sensor (S2) (S15), it is determined whether or not within time (S16) In step S11, if the time is determined, the object 101 is jammed. Then, the jam alarm is driven to stop the second motor M2 to terminate the system (S17 to S18). ).

As described above, when the front end of the object 11 is detected by the second sensor S2, the second motor M2 is stopped and the read module driving information is transmitted to the controller 801 for reading (S13). The reader 400a and the character recognizer 400b are driven to read a bar code or a character printed on the object.

Subsequently, the object in which the barcode or the character is read is continuously transferred, and the timer is detected by the third sensor S3 initialized (S14), and whether the arrival of the object is detected (S19). When the determination result is detected, the printer module driving information is transmitted to the controller 801 and the timer of the fourth sensor S4 is set at step S20.

On the other hand, when it is determined that the object arrival detection of the third sensor (S3), if not detected, the timer value is compared to determine whether it is within time (S21 to S22), and if it is within the time, the arrival of the object continues. In operation S19, if the time is later, the jam alarm is driven to stop the second motor M2, and the system is terminated (S17 to S18).

On the other hand, when the front end of the object arrives is sensed by the third sensor S3, the controller 801 received the printer module driving information transmits a command to the printer 500 to print the read information on the object. (S20).

After a predetermined time by the printer module driving information transmitted as described above, the printer 500 operates to print the corresponding contents on the object, and the controller 801 is configured to obtain information (barcode, text, etc.) acquired while the object is being transferred. After determining whether or not the end of the object has passed through the fourth sensor S4 (S23), if it is detected that the result of the determination is passed (S24), a reading result is generated (S24) through the processing result transmitter 803 If the fourth sensor S4 does not detect the arrival of the object as a result of the determination, the timer value of the fourth sensor S4 is compared and it is determined whether it is within time (S25 to S26). If it is determined that the time is within the time, the arrival of the object continues to be detected (S33). If after the time, the jamming alarm is generated and the second motor M2 is stopped to terminate the system (S17 to S18).

If the reading result is determined to be an error, the result indicator (marking system) is operated by the command of the controller 801 to display the error and the result indication on the object 11, and then to restart the timer of the fifth sensor S5. Initialize (S27), determine whether the fifth sensor (S5) has detected the arrival signal of the object (S28), and if the determination result detects the arrival signal, initializes and sets the timer (S5) of the fifth sensor again. (S29).

If the arrival signal of the object is not detected, after comparing the timer value of the fifth sensor S5 and determining whether it is within time (S30), and if the determination result is within the time, the fifth sensor S5 again detects the object. It is determined whether or not the arrival signal is detected (S31), and if the time after the determination result, the object is stuck, generates a jamming alarm and stops the second motor (M2) to terminate the system (S32 to S33).

Subsequently, as a result of determining whether the object 11 continuously transported by the third driving roller 200c and the third support roller 300c has been discharged (S34), when the object is discharged, if the object remains in the supply container for the first time, Perform the command from (S3).

On the other hand, if the object is not discharged, and compares the timer value of the fifth sensor (S5) and determines whether it is within the time (S35 ~ S36), if the determination result within the time to determine whether the object discharged (S34) If thereafter, a jamming alarm is generated and the second motor M2 is stopped to stop the system (S32 to S33).
