Moreover, if the information printed or attached on the upper surface of the article is character information, a member capable of reading the character information as digital information is preferable. The scanner unit 103 outputs the read information to the control unit 109.

  The first sensor unit 104 detects position information of a reference point set in advance on an article. Specifically, the first sensor unit 104 is configured of a photoelectric sensor. The first sensor unit 104 has a first state in which light emitted from the first sensor unit 104 is blocked by an article conveyed to the first region, and a second state in which light passes through a hole provided in the article. Can detect Thereby, when the article is rotated by the first rotation drive unit 102, the control unit 109 can detect the position of the reference point provided on the article shown in FIG. 2 as the first state or the second state.

  The second rotation drive unit 105 is a member that rotates an article conveyed by the information addition device 100 on a horizontal surface. The second rotation driving unit 105 is disposed in the vicinity of the third region of the conveyance path of the conveyance unit 101. The second rotation driving unit 105 is connected to a motor (not shown), and the control unit 109 controls the motor to drive the motor, and as a result, the motor rotates about a rotation axis set in a substantially vertical direction.

  Specifically, when an item is conveyed to the second region by the information addition device 100, the second rotation driving unit 105 sandwiches the item from above and below. Then, the second rotation drive unit 105 rotates the article around the set rotation axis in a state in which the article is sandwiched.

Moreover, if the information printed or attached on the upper surface of the article is character information, a member capable of reading the character information as digital information is preferable. The scanner unit 107 outputs the read information to the control unit 109.

  The printer unit 108 prints information based on the code information read by the scanner unit 103 on a label and outputs it. And it sticks on the label article which printed the above-mentioned information using the pasting mechanism which is not illustrated. Although the configuration in which the information based on the code information is printed on the label has been described above, the information may be directly printed on the article.

  The printer unit 108 has an arm mechanism (not shown). This arm mechanism is provided with a label gripping unit that sucks the label issued to the tip. After issuing the label, the printer unit 108 holds the label by the label holding unit and attaches the held label to the article.

  The control unit 109 controls the entire information adding apparatus 100 according to a computer program described in software or firmware.

  Hereinafter, the operation of the information adding apparatus 100 by the control unit 109 will be described with reference to the drawings.

(Operation)
The processing operation of the control unit 109 will be described below with reference to the drawings.

  FIG. 4 is a flowchart for explaining the operation in the first area performed by the control unit 109.

  First, when an article is input from the outside, the control unit 109 controls the conveyance unit 101 to convey the inserted article to the first region on the conveyance path (S101).

  Next, the control unit 109 controls the first rotation drive unit 102 to sandwich the article conveyed to the first region from above and below so that the article can rotate on the horizontal surface. Furthermore, the control unit 109 controls the motor (not shown) to rotate the first rotation drive unit 102 about a predetermined rotation axis, and as a result, rotates the article on a horizontal surface.

  At this time, the control unit 109 controls the rotation operation based on the signal from the first sensor unit 104. Specifically, when the article is transported to the first area, the control unit 109 can determine that the article is in the first state based on the signal from the first sensor unit 104. From this state, the control unit 109 causes the article to rotate in the first direction on the horizontal surface at a first rotation speed when the article is viewed from the upper side substantially in the vertical direction (S102).

  The control unit 109 determines whether the position of the reference point in the article is in the first state or the second state based on the signal from the first sensor unit 104 when the article is continuously rotated at most 360 degrees. Do. At this time, when the control unit 109 determines that the first state has changed to the second state, the control unit 109 stops the rotation operation of the article by the first rotation driving unit 102 (S103).

  After stopping the rotation operation in S103, the control unit 109 determines again whether or not the second state is based on the signal from the first sensor unit 104 (S104). If the control unit 109 determines that the second state is set, the process proceeds to step S106. On the other hand, when the rotation operation of the article is stopped, the inertia force acting on the article may not immediately stop the rotation of the article, and may change again from the second state to the first state. By this operation, when the control unit 109 determines that the second state is not set, the process proceeds to S105.

  When it is determined in S104 that the position of the reference point on the article is not in the second state, the control unit 109 horizontally views the article in a second direction opposite to the first direction when the article is viewed from the upper side substantially in the vertical direction. The rotation is performed at the second rotation speed (S105). Here, in the above, when rotating in the second direction, the rotation direction is changed to the first direction. In short, it is rotated in the direction opposite to the rotation direction in the previous rotation operation. Then, the control unit 109 shifts to S103 again.

  Here, the first rotational speed is preferably higher than the second rotational speed. By this control, after stopping the rotating article, it is possible to reduce the time for which the article continues to rotate by the inertia force. Thereby, compared with the case where it rotates at fixed rotation speed, the time concerning positioning can be shortened.

  The control unit 109 stops the reference point on the article at the position of the second state by repeating S103 to S105.

  In the above, when the rotation operation in the first direction, the stop operation, and the rotation operation in the second direction are repeated, the control unit 109 is preferably controlled to reduce the rotation speed each time the direction of rotation is switched.

  After stopping the position of the reference point of the article in the second state, the control unit 109 controls the scanner unit 103 to read code information printed or attached on the top surface of the article (S106). The control unit 109 specifies predetermined information based on the read code information, and outputs the specified information to the printer unit 108.

  Next, the control unit 109 controls the first rotation driving unit 102 before transporting the article from the first area to the third area, thereby setting the article in one of the first direction and the second direction. It is rotated (S107). Specifically, when the article is conveyed to the second region, the control unit 109 rotates the article so as not to be detected as the second state by the second sensor unit 106.

  For example, as shown in FIG. 2, when the conveyance path is set on a virtually set straight line, the reference point of the article conveyed from the first area to the second area via the third area is The conveyance error in the conveyance unit 101 may cause a slight deviation from the straight line. In this case, depending on the rotation direction of the second rotation drive unit 105 in the second region, it is necessary to rotate about 360 degrees until the position of the reference point of the article changes from the first state to the second state. In the case of about 360 degrees of rotation, the rotational speed when changing from the first state to the second state is higher than that in the case of, for example, 40 degrees of rotation. Therefore, the time from when the rotation is stopped to when the article actually stops is long. As a result, the time required for the article to stand still in the second state is increased.

  On the other hand, if the article is rotated before being transported from the first area to the third area, the position of the reference point of the article is first required to change from the first state to the second state in the second area Although the minimum rotation angle increases, the maximum rotation angle decreases. When a plurality of articles are processed continuously, the maximum rotation angle required to change from the first state to the second state is reduced as described above. In short, instead of increasing the minimum time taken for the position of the reference point of the article to change from the first state to the second state, the maximum time taken to change from the first state to the second state is increased. This makes it possible to streamline the entire process across multiple articles.

  Next, the control unit 109 controls the conveyance unit 101 to convey the input article from the first area to the third area on the conveyance path (S108).

  The control unit 109 operates in the first area as described above.

  Hereinafter, the operation in the second region of the control unit 109 will be described with reference to the drawings.

  FIG. 5 is a flowchart for explaining the operation in the first area performed by the control unit 109.

  The control unit 109 controls the transport unit 101 to transport the articles staying in the third region to the second region on the transport path (S201).

  Next, the control unit 109 controls the second rotation driving unit 105 to sandwich the article conveyed to the second region from above and below so that the article can rotate on the horizontal surface. Furthermore, the control unit 109 controls the motor (not shown) to rotate the second rotation driving unit 105 around a predetermined rotation axis, and as a result, rotates the article on the horizontal surface.

  At this time, the control unit 109 controls the rotation operation based on the signal from the second sensor unit 106. Specifically, when the article is transported to the second area, the control unit 109 can determine that the current position is in the first state based on the signal from the second sensor unit 106. From this state, the control unit 109 causes the article to rotate on the horizontal surface at a third rotation speed in one of the first direction and the second direction when the article is viewed from above the substantially vertical direction (S202) ).

  When the article is continuously rotated, the control unit 109 determines, based on the signal from the second sensor unit 106, whether or not the position of the reference point of the article has changed from the first state to the second state. When determining that the position of the reference point of the article has changed from the first state to the second state, the control unit 109 stops the rotation operation of the article by the first rotation driving unit 102 (S203).

  After stopping the rotating operation of the article, the control unit 109 determines again whether or not the second state is based on the signal from the second sensor unit 106 (S204). If the control unit 109 determines that the position of the reference point of the article is in the second state, the process proceeds to step S206. On the other hand, when the rotation operation of the article is stopped, the inertia force acting on the article may not immediately stop the rotation of the article, and may change again from the second state to the first state. Accordingly, when the control unit 109 determines that the position of the reference point of the article is not in the second state, the process proceeds to step S205.

  If it is determined in S204 that the state is not the second state, the control unit 109 rotates the article on the horizontal surface at the fourth rotation speed in the direction opposite to the previous rotation direction (S205). Then, the control unit 109 shifts to S203 again.

  Here, the third rotational speed is preferably higher than the fourth rotational speed. By this control, after stopping the rotating article, it is possible to reduce the time for which the article continues to rotate by the inertia force. Thereby, compared with the case where it rotates at fixed rotation speed, the time concerning positioning can be shortened.

  The control unit 109 stops the article in the second state by repeating S203 to S205.

  In the above, the control unit 109 is preferably controlled to reduce the rotational speed each time the direction of rotation is switched. Here, the rotational speed may be an average speed before switching the direction of rotation, or may be a rotational speed immediately before switching the direction of rotation.

  After stopping the article in the second state in the second region, the control unit 109 controls the scanner unit 107 to read code information printed or attached on the top surface of the article (S206).

  Then, the control unit 109 determines whether the information specified based on the code information read by the scanner unit 107 matches the information specified based on the code information read by the scanner unit 103 (S207).

  If the two pieces of specific information match, the control unit 109 controls the printer unit 108 to print the specified information on the label, and affix the label on which the information is printed on the upper surface of the article (S208 ).

  Then, the control unit 109 discharges the article attached with the label downstream from the second region (S209).

  On the other hand, when the specific information does not match, the control unit 109 discharges the article as it is (S209).

  The control unit 109 operates in the second area as described above.

  The control unit 109 repeatedly executes the operations described in FIG. 4 and FIG. 5 until the supply of articles is lost.

(Summary)
A conveying unit 101 that conveys an article supplied from the outside, and a member disposed in the vicinity of a first area in a conveying path of the conveying unit 101, when the article is conveyed to the first area by the conveying unit 101, A first rotation drive unit 102 for rotating an article on a predetermined plane, scanner units 103 and 107 for reading code information of the article, and a first sensor unit 104 for detecting position information of a reference point preset for the article. And a second sensor unit 106, and a member disposed in the vicinity of a second region set downstream of the first region in the transport route of the transport unit 101, the article being transported by the transport unit 101 to the second region And a control unit 109, and a second rotation drive unit 105 that rotates an article on a flat surface, a printer unit 108 that adds information based on code information to the article, and a control unit In 09, after the article is transported to the first area by the transport unit 101, the first rotation drive unit 102 is based on the position information of the reference point (the hole in the above embodiment) detected by the first sensor unit 104. The article is rotated so that the reference point becomes the first reference position (the second state in the first area in the above embodiment) in which the reference point is set in advance, and the reference point is the first reference in the first area. When arranged at the position, the scanner unit 103 is controlled to read code information, and after the code information reading is completed, the article is conveyed by the conveyance unit 101 to the second area, and the article is transmitted to the second area. After being transported, the second rotation drive unit 105 is controlled based on the position information of the reference point detected by the second sensor unit 106, whereby a second base is set in advance. The article is rotated to be at the position (in the above embodiment, the second state in the second area), and when the reference point is arranged at the second reference position in the second area, the printer unit 108 is controlled to Information is added to the article based on the code information, and further, when the article is transported from the first area to the second area, the first reference point is disposed at a position deviated from the second reference position. After the rotary drive unit 102 is controlled to read the code information, the article is further rotated and transported from the first area to the second area.

  Thus, the control unit 109 rotates the article so as to be detected by the first state and the second sensor unit 106 when being transported to the second area after the article is brought into the second state in the first area. be able to.

  For example, as shown in FIG. 2, when the conveyance path is set on a virtually set straight line, the reference point of the article conveyed from the first area to the second area via the third area is The conveyance error in the conveyance unit 101 may cause a slight deviation from the straight line. In this case, depending on the rotation direction of the second rotation drive unit 105 in the second region, it is necessary to rotate about 360 degrees until the position of the reference point of the article changes from the first state to the second state. In the case of about 360 degrees of rotation, the rotational speed when changing from the first state to the second state is higher than that in the case of, for example, 40 degrees of rotation. Therefore, the time from when the rotation is stopped to when the article actually stops is long. As a result, the time required for the article to stand still in the second state is increased.

  On the other hand, if the article is rotated before being transported from the first area to the third area, the position of the reference point of the article is first required to change from the first state to the second state in the second area Although the minimum rotation angle increases, the maximum rotation angle decreases. When a plurality of articles are processed continuously, the maximum rotation angle required to change from the first state to the second state is reduced as described above. In short, instead of increasing the minimum time taken for the position of the reference point of the article to change from the first state to the second state, the maximum time taken to change from the first state to the second state is increased.

  When configured as described above, when performing positioning control at least twice for each of a plurality of articles, instead of lengthening the minimum processing time required for the second and subsequent positioning control, the maximum processing time is shortened. An information adding apparatus for speeding up the processing time of the entire plurality of articles.

  More preferably, in the present embodiment, when the control unit 109 controls the rotation of at least one of the first rotation drive unit 102 and the second rotation drive unit 105, the rotation speed at the start of the rotation of the article is the article Set faster than the rotation speed before the end of rotation.

  Preferably, when controlling the rotation of at least one of the first rotation driving unit 102 and the second rotation driving unit 105, the control unit 109 changes the rotation direction every time the rotation direction of the article is switched. Set a lower average speed.

  Preferably, in the present embodiment, (1) when the reference point is disposed at the second reference position in the second region, the control unit 109 is disposed in the second region by controlling the scanner unit 107. The code information of the article to be read, (2) it is determined whether the information based on the read code information matches the information to be added to the article, and (3) the information based on the read code information, Only when the information to be added matches the information to be added, the printer unit 108 is controlled to add the information based on the code information to the article.

  As a result, it is possible to determine whether the information based on the code information read at the first positioning and the information based on the code information read at the next positioning are matched. Therefore, even if the articles are replaced during transport from the first area to the second area due to some cause, appropriate information can be added without a mistake.

It is different. Specifically, the scanner unit 103 and the first sensor unit 104 are disposed at positions deviated from the virtual straight line set in the conveyance path shown in FIG. That is, even if the article when positioned in the first area is conveyed to the second area as it is, the reference point of the article is not located in the vicinity of the reading area of the second sensor unit 106. That is, as described in the above embodiment, after positioning the article in the first area by the control unit 109, the same operation and effect can be achieved without rotating the article.
