Description

  The present invention relates to a packaging device that inserts a predetermined number of individual thin laminated plates or single plates used for electronic parts, medical parts, sensors, foods, and the like into a storage box.

  A conventional thin plate packaging apparatus will be described with reference to the drawings. FIG. 6 is a cross-sectional view of a main part of a conventional thin plate packaging apparatus.

  In FIG. 6, the thin plate 17 is placed as a single piece on a conveying belt 19 having a bar partition on the surface at a constant pitch by an alignment device (not shown). The conveyor belt 19 is intermittently fed by the driving pulley 20 while being regulated by the pop-out prevention guide 18 with the pitch dimension of the crosspiece. A cutout portion is provided in a part of the pop-out prevention guide 18, and the thin plate 17 that has reached that portion without guide regulation is transferred to the bucket 21 by its own weight. The thin plate is transferred to the bucket 21 by counting the passage of the thin plate with the photoelectric sensor 23, stopping the intermittent operation of the drive pulley 20 when the predetermined number is reached, and opening the lower shutter 22 of the bucket 21. It is inserted into the storage box 24.

  The number of thin plates transferred to the storage box 24 is finally measured by weighing with an electronic balance with the thin plate in the storage box 24.

As prior art document information relating to this application, for example, Patent Document 1 is known.

  However, the conventional apparatus has the following problems. When the individual thin plate 17 is extremely light, in the case of a variation in cutting dimensions, or in the case of a laminated structure, a difference occurs in the difference from the basic weight for the number of sheets due to variations in the amount of adhesive in the bonded portion, etc. It may not be possible to judge whether the correct number of sheets is stored.

  Moreover, the transfer of the thin plate 17 to the bucket 21 and the storage box 24 may not be performed normally due to the effect of static electricity or the like that occurs when the adhesive in the laminated structure or the thin plate is a resin material due to free fall.

  In order to solve the above problems, the present invention measures the number of sheets by image recognition in a state where a predetermined number of sheets are overlapped with the directionality of the shape of the thin plate. As a result, the reliability of the number measurement is remarkably improved.

In order to solve the above-described conventional problems, a thin plate packaging apparatus of the present invention includes a thin plate provided at one end and having a step with respect to the thickness direction, a regulating member that stacks a plurality of the thin plates in accordance with the shape of the left and right, upper and lower surfaces, A recognition device that captures images of these stacked thin plates and measures the number thereof and a storage box that stores the stacked thin plates, the recognition device has a light source, and the light from the light source The number of the thin plates is measured by irradiating from the side surface in the longitudinal direction of the thin plate so as to transmit light , and it becomes possible to capture a stable image by utilizing the shape characteristics of the thin plate , and the number of the plates is measured. Can improve the reliability.

  In addition, the packaging device of the present invention regulates the outer periphery while stacking the thin plates one by one, and holds the posture of the thin plate by pressing the superimposed uppermost surface with a concave member, and the thin plate sucked by the same member Can be removed at a predetermined position, the number of sheets can be measured in a stacked state, and transferred to an adjacent storage box.

  As described above, according to the thin plate packaging apparatus of the present invention, the thin plate is stacked, and a condition for capturing the images of the stably stacked thin plates is created using the shape characteristics of a part of the thin plate packaging apparatus. By using it, the reliability of the number measurement can be improved.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

(Embodiment 1)
1 and 2 are perspective views of the packaging device according to Embodiment 1 of the present invention, and FIG. 3 is a local cross-sectional view taken along arrow B in FIG. The piece-like thin plates 1 are stacked in the thickness direction with the shape of the left and right and up and down directions, the lower part is the backup 3, the outer periphery is the side guide A5, the side guide B6 and the slide stopper 4, and the upper surface is the restriction of the concave member 2. Each member is regulated. The side guide A5 is provided with a notch so that a part of the stacked thin plates 1 can be directly viewed from the direction of the arrow A, and the recognition device 10 and the ring illumination 9 are installed in front of the recognition device 10 from the direction of the arrow A, Let me monitor. Further, a notch is also provided in a part in the direction of the arrow B in the configuration with the guide B6, and a dimension for inserting the pusher 11 is secured. When inserting a predetermined number of stacked thin plates 1 into the storage box 8, the concave member 2 pressed by the spring 7 is moved upward to release the upper restriction and lower the slide stopper 4. Thereafter, the pusher 11 is advanced and inserted. Here, the opening of the storage box 8 is set so as to face in the horizontal direction in advance. As shown in FIG. 3, the pusher 11 and the backup 3 can be inserted into the storage box 8 without fail regardless of the thickness of the thin plate by combining the shapes of the pusher 11 and the backup 3 with each other.

  The thin plates 1 are individually aligned on a conveyor belt 14 having convex partitions at a constant pitch by an alignment device (not shown), and the thin plates 1 are conveyed at a constant pitch via a timing pulley 15. The thin plate 1 on the conveyor belt is sucked in vacuum by the suction pad 16 and moved to the stacking position by a pick and place device. FIG. 4 is an operation system diagram thereof. Immediately after moving to the stacking position, the thin plate 1 sucked by the suction pad 16 is positioned below the concave member 2 (state diagram (1)), and the concave member 2 Is lowered from the suction pad 16 and stacked one after another (state diagram (2)). At this time, the back-up 3 is lowered by the thickness dimension of the thin plate 1 so that the overlapping height is always kept the same (state diagram (3)).

  FIG. 5 is an enlarged view of the main part from the arrow A in FIG. 1. Regarding the number measurement of the thin plate 1 by the recognition device 10, a step existing as a part in the thickness direction of the thin plate or a step is added to the ring. In the recognition device 10 with the light source of the illumination 9, each thin plate can be replaced with clear light shading, and a stable image can be produced. The number of thin plates 1 is measured by using a function of counting the number of edges from black to white by moving the measurement points from the top to the bottom in the inspection area D. Note that when the number of sheets is measured by the recognizing device 10, the thin plate 1 needs to be aligned and stacked, so that the concave member 2 is held by the force of the spring 7.

A thin plate packaging apparatus according to the present invention includes a thin plate that is provided at one end and has a step in the thickness direction, a regulating member that stacks the thin plates in a right-and-left manner, and a shape that matches the shape of the upper and lower surfaces, and images of the stacked thin plates A recognition device for capturing and measuring the number of sheets; and a storage box for storing the stacked thin plates. The recognition device includes a light source, and the light from the light source is transmitted through the step so that the light is transmitted through the step. Measures the number of thin plates by irradiating from the side in the longitudinal direction, and measures the shape of a portion of the thin plates, improving the reliability of the number measurement, so it can be used for thin plates such as chemical or medical test papers, etc. Useful for.
