A ratio of dimensions of an object drawn in a drawing may be different from a ratio of dimensions of an actual object. The dimensional ratio of the object may be different between the drawings. The specific dimensional ratio of the object should be determined in consideration of the following description.

  The glass tube boxing device 1 shown in FIGS. 1 to 4 is capable of suitably packing a short cylindrical tubular glass tube having a ratio of length to diameter ((length) / (diameter)) of 5 or less. It is. The boxing device 1 is suitably used for boxing a glass tube having a length of 10 mm or less, and further a glass tube having a length of 8 mm or less. Examples of such a glass tube include a glass tube for a reed switch.

  1 to 4 each show only a part of the boxing device 1. The boxing device 1 includes a part shown in FIGS. 1 and 3 and a part shown in FIGS. 3 and 4 are views showing a state after the second desorption step described later is performed a plurality of times. In this embodiment, FIGS. The desorption process, the first second movement process, the first second desorption process, and the like are also incorporated.

  The boxing device 1 includes a suction head 10, a moving mechanism 20, and a control unit 30. The suction head 10 is a head in which a plurality of glass tubes 40 aligned along a direction perpendicular to the length direction of the glass tube 40 can be attached and detached. The suction head 10 can be moved by the moving mechanism 20. The suction head 10 and the moving mechanism 20 are each connected to the control unit 30 and controlled by the control unit 30.

  As shown in FIGS. 1 and 2, the control unit 30 first has a plurality of glass tubes aligned along the x-axis direction that is a direction perpendicular to the length direction of the glass tube 40 at the suction position. 40 is adsorbed by the adsorption head 10 (first adsorption step).

  As shown in FIGS. 3 and 4, after the first suction step, the suction head 10 is moved into the box 50 by the moving mechanism 20 in accordance with a command from the control unit 30 (first movement step). Here, the box 50 is arranged on the installation table 60 so as to open sideways (specifically, in the y-axis direction). The box 50 includes a bottom wall portion 51, a back wall portion 52, and side wall portions 53 and 54 (see FIG. 4).

  After the first moving process, the plurality of glass tubes 40 are desorbed from the suction head 10 according to the command of the control unit 30 (first desorbing process). Thereby, a row of glass tubes 40 can be arranged in the box 50.

  After the first desorption step, the suction mechanism 10 is moved again to the suction position of the glass tube 40 by the moving mechanism 20 according to the instruction of the control unit 30, and then, as shown in FIGS. 1 and 2, A plurality of other glass tubes 40 aligned along the x-axis direction, which is a direction perpendicular to the length direction of the glass tube 40, are adsorbed by the adsorption head 10 (second adsorption step).

  After the second suction step, as shown in FIGS. 3 and 4, the suction mechanism 10 is moved above the plurality of glass tubes 40 in the box 50 by the moving mechanism 20 in accordance with a command from the control unit 30 ( Second moving step).

  After the second moving process, the control unit 30 detaches the plurality of other glass tubes 40 from the suction head 10 and arranges them in a row on the plurality of glass tubes 40 previously arranged in a row in the box 50. Place (second desorption step).

  By repeating the second adsorption process, the second movement process, and the second desorption process in accordance with an instruction from the control unit 30, the plurality of glass tubes 40 are filled in a matrix in the box 50.

  In the boxing method of the glass tube 40 of the present embodiment, the glass tube 40 remains adsorbed by the adsorption head 10 until the glass tube 40 is installed in the box 50. Therefore, the rotation of the glass tube 40 is suppressed, and the glass tube 40 can be suitably packed in the box 50. Further, for example, even when a smaller number of glass tubes 40 than the desired number are adsorbed to the adsorption head 10, the glass tubes 40 placed in the box 50 roll along the circumferential direction and are closely packed. To go.

  From the viewpoint of enabling the glass tube 40 to be placed more orderly in the box 50, the other plurality of glass tubes 40 sucked by the suction head 10 are already placed in the box 50 in the second desorption step. It is preferable that the other plurality of glass tubes 40 be detached from the suction head 10 while pressing toward the plurality of glass tubes 40 placed.

  In the boxing device 1, a drop-off suppressing plate 70 is disposed in front of the box 50. Before the first detachment step is performed, the drop-off suppressing plate 70 is located below the bottom wall portion 51 of the box 50. After the first dropout process is performed, at least one of the dropout suppression plate 70 and the box 50 moves relatively, and the dropout suppression plate 70 is positioned in front of the glass tube 40 placed in the box 50. In addition, even after the second drop-off process is performed, at least one of the drop-off suppression plate 70 and the box 50 moves relatively, and the drop-off suppression plate 70 is placed in front of the glass tube 40 placed in the box 50. Located in. For this reason, dropping of the mounted glass tube 40 from the box 50 is effectively suppressed.

  Moreover, you may incline the installation stand 60 or the box 50 so that the edge part of the glass tube 40 which touches the back wall part 52 of the box 50 may fall, and an other end part may go up. Thereby, it is suppressed more effectively that the glass tube 40 falls from the box 50. Note that when the installation table 60 or the box 50 is tilted, the suction head may be tilted in accordance with the tilt.

  In addition, the drop-off suppression plate 70 may be moved relative to the box 50 by moving the drop-off suppression plate 70, or the drop-off suppression plate 70 is moved with respect to the box 50 by moving the box 50. You may move relatively. Further, the drop-off suppressing plate 70 may be moved relative to the box 50 by moving both the drop-off suppressing plate 70 and the box 50.
