Description

  The present invention relates to an apparatus for collecting blister products.

  The blister product includes a container member having a pocket portion and a flange portion formed around the pocket portion, contents contained in the pocket portion, and a cover member attached to the flange portion. . The blister product is manufactured through a known blister packaging machine, and is shipped in a state where a plurality of blister products are collected. More specifically, blister products are grouped in the form of boxing (cartning), bagging, band tying, or pillow packaging.

  As a conventional method for assembling blister products, there are products in which a large number of blister products are stacked (for example, see Patent Document 1).

Japanese Patent Laid-Open No. 11-155948 (FIG. 4)

  However, in consideration of packing, etc., when a plurality of blister products are stacked in a parallel flat state as in Patent Document 1, a wasteful space (space) is required, and the size of the box is inevitably increased. End up. In addition, it is conceivable to pack the boxes by so-called vertical stacking so that the flange portions face the vertical direction. However, in this case as well, the actual situation is that the downsizing is not possible.

  Further, regarding the upper and lower blister products with the pocket portions facing each other, it is conceivable that the pocket portions are stacked in a so-called tying state so that the pocket portions are positioned between the opposite flange portions. However, when the pocket portion itself is large (when the width of the flange portion is narrower than that of the pocket portion), the effect of tying cannot be expected, and the size reduction cannot be achieved so much.

  The present invention has been made in view of the above circumstances, and provides a blister product stacking apparatus that can achieve a significant compactness regardless of the size of the pocket portion when collecting a plurality of blister products. One of the main purposes.

  In the following, each means suitable for solving the above-described object will be described in terms of items. In addition, the effect specific to the means to respond | corresponds as needed is added.

Therefore, it is not necessary to use a separate actuator such as a motor and a cylinder other than the transfer means, and the above-described superposition can be realized along with the transfer by the transfer means. Therefore, it is possible to suppress an increase in cost without causing a complicated configuration. In other words, the above-described effects can be achieved with a relatively simple configuration.

Means 3. The support means includes a first support portion that supports one side portion of the flange portion of each blister product, and a second support portion that supports the other side portion of the flange portion of each blister product,

  Hereinafter, an embodiment will be described with reference to the drawings.

  As shown in FIGS. 3 (a) and 3 (b), the blister product 11 in this embodiment includes a plastic container member 14 having a pocket portion 12 and a flange portion 13 formed around the pocket portion 12, A paper cover member 15 attached to the flange portion 13 is provided, and the contents 16 are accommodated in the pocket portion 12. The blister product 11 is manufactured through a known blister packaging machine, and is obtained by punching one by one in the final process of the blister packaging machine, and then conveyed downstream by a conveyor or the like. .

  The conveyed blister products 11 are arranged in parallel in a plurality of rows (5 rows in the present embodiment) and then guided to the stacking device 21 (see FIG. 4 and the like) according to the present embodiment. Then, after the plurality of blister products 11 are accumulated in the accumulating device 21, they are adsorbed and moved by an adsorption moving means 51 described later and used for boxing.

  More specifically, in this embodiment, as shown in FIGS. 1 and 2, for example, 5 rows × 3 stages of blister products 11 are accommodated in a box 18. In packaging, five rows of blister products 11 are accommodated in the box 18 at a time in a state where the flange portions 13 of the blister products 11 adjacent to each other are overlapped, and the accommodating operation is repeated three times. Stacked.

  Next, the configuration of the accumulation device 21 of this embodiment will be described.

  FIG. 4 is a schematic plan view showing the integration device 21 in the present embodiment. As shown in the figure, the stacking apparatus 21 includes one rail block 22 that constitutes a superimposing means and a transfer means. The rail block 22 is installed in a fixed state and has five grooves 23 having a U-shaped cross section. Corresponding to each groove 23, a push pin 24 constituting the transfer means is provided so as to be movable in a suspended state. And each push pin 24 is moved all at once by the moving apparatus which is not shown in figure, and each blister product 11 mounted corresponding to each groove part 23 is conveyed along the groove part 23. FIG. .

  In the present embodiment, the rail block 22 is divided into four zones (a first zone 31, a second zone 32, a third zone 33, and a fourth zone 34) (see the one-dot chain line in FIG. 4). As shown in FIGS. 4 and 5, in the first zone 31, the blister products 11 conveyed from the blister packaging machine are arranged in parallel while maintaining their horizontal state with the pocket portion 12 facing downward. Transported in state. That is, in the first zone 31, the blister product 11 is supported from below on the bottom wall surface of the groove 23 and the upper wall surfaces on both sides of the groove 23, and the blister product 11 slides on the support surface. (It may be supported in a suspended state only on the upper wall surfaces on both sides of the groove 23). In the 1st zone 31, the space | interval between each groove part 23 is fully ensured, and the blister product 11 which adjoins does not contact | abut.

  In the first zone 31, the bottom wall surface of the groove portion 23 and the upper wall surfaces on both sides of the groove portion 23 constitute support means, and the left and right side surfaces of the groove portion 23 constitute guide means.

  Moreover, in the 2nd zone 32 located in the downstream of the 1st zone 31, as shown in FIG.4, 6, the blister product 11 is conveyed in the parallel state, being tilted in a fixed direction. That is, in the second zone 32, the blister product 11 is supported from below on the bottom wall surface of the groove 23, and the blister product 11 is slid on the support surface (one side of the groove 23). The flange portion 13 may hit and be supported on the upper wall surface (or corner portion). In the second zone 32, the meat part (the meat part on the left side of the groove part 23 in FIG. 5) supporting the flange part 13 on the other side of the blister product 11 in the first zone 31 is cut off. Only the groove 23 is widened. Under such a configuration, each blister product 11 moved to the second zone 32 has the center of the pocket portion 12 forming a curved surface, and the one-side flange portion 13 that has been supported so far is not supported. Based on this, it is tilted so as to fall down. In the second zone 32 as well, the space between the groove portions 23 is sufficiently secured, so that the adjacent blister products 11 do not come into contact with each other.

  In the second zone 32, the bottom wall surface of the groove portion 23 mainly constitutes support means, and both side surfaces of the groove portion 23 constitute guide means. Further, the bottom wall surface formed by scraping the flesh portion of the groove portion 23 constitutes the first support portion, and the opposite convex portion supporting the flange portion 13 constitutes the second support portion.

  Furthermore, in the 3rd zone 33 located in the downstream of the 2nd zone 32, as shown in FIG.4, 7, the blister product 11 which inclines in the fixed direction is conveyed, approaching mutually. That is, in the third zone 33, the interval between the groove portions 23 is narrowed toward the downstream side, and the convex portion between the groove portions 23 is formed to become lower toward the downstream side. Also in the third zone 33, the blister product 11 is supported from the lower side on the bottom wall surface of the groove 23, and the blister product 11 is slid on the support surface. However, in the third zone 33, as described above, since the interval between the groove portions 23 is narrowed toward the downstream side, the adjacent blister products 11 are brought close to each other. Furthermore, since the convex part between the groove parts 23 is formed so as to become lower toward the downstream side, the flange parts 13 of the adjacent blister products 11 are brought together so as to overlap each other. At this time, since each blister product 11 is inclined in a certain direction, a height difference is derived between the flange portions 13 of the blister product 11. Therefore, problems such as the flange portions 13 abutting each other at the time of width adjustment do not occur.

  In the third zone 33, the bottom wall surface of the groove portion 23 constitutes support means, and in the upstream portion of the third zone 33, both side surfaces of the groove portion 23 constitute guide means, and from the middle both ends in the width direction. The outer side surfaces of the two groove portions 23 constitute guide means. Moreover, each said side surface of the 3rd zone 33 comprises a width adjusting mechanism.

  In addition, in the fourth zone 34 located on the downstream side of the third zone 33, as shown in FIGS. 4 and 8, the blister product 11 that has been inclined in a certain direction until then is gradually brought closer to the horizontal state. While being transported. That is, in the 4th zone 34, the convex part between the groove parts 23 (part which supports the both-sides flange part 13 of the blister product 11) is formed so that it may become high gradually toward the downstream. Therefore, in the fourth zone 34, the blister product 11 is supported from below on the bottom wall surface of the groove 23 and the convex portions on both sides thereof, and the blister product 11 slides on the support surface. It is done. However, in the fourth zone 34, the flange portions 13 of the adjacent blister products 11 are already overlapped with each other, and can be brought close to the horizontal state while maintaining the overlapping state.

  In the fourth zone 34, the bottom wall surface of the groove 23 and the convex portions on both sides thereof constitute support means, and in the upstream portion of the fourth zone 34, the outer side surfaces of the two groove portions 23 at both ends in the width direction are guides. In addition to constituting the means, both side surfaces of the groove 23 form guide means from the middle.

  Further, in the present embodiment, the suction moving means 51 is movably provided corresponding to the fourth zone 34. Then, the blister product 11 in which the flange portions 13 are overlapped with each other approaching the horizontal state is sucked together by the suction moving means 51 and is moved to the box 18 while maintaining the suction state.

  As described in detail above, according to the present embodiment, the plurality of blister products 11 in parallel with each other are transferred along the groove 23 by the push pin 24. And regarding the blister product 11 in a transfer process, the flange parts 13 of the blister product 11 adjacent to each other are overlapped. As a result, the entire width of the group of blister products 11 in the parallel state is narrowed. Finally, the blister product 11 group is accommodated in the box 18 in a state where the flange portions 13 are overlapped with each other. For this reason, useless space will be narrowed and more compact boxing can be realized. In particular, the above-described effects can be reliably achieved even when the pocket portion 12 is relatively large.

  In this embodiment, the rail block 22 is provided with a support function and a guide function, and the height difference between the flange portions 13 of the blister products 11 adjacent to each other is derived based on the height difference of the support means (second). In the zone 32), the flange portions 13 of the blister products 11 adjacent to each other are overlapped on the basis of the width adjusting mechanism of the guide means (third zone 33). Therefore, it is not necessary to use a separate actuator such as a motor or a cylinder other than the moving means for moving the push pin 24, and the above-described superposition can be realized with the transfer by the push pin 24. Therefore, it is possible to suppress an increase in cost without causing a complicated configuration. In other words, the above-described effects can be achieved with a relatively simple configuration.

  Further, in the present embodiment, in the second zone 32, the groove portion 23 is widened correspondingly by scraping away the meat portion that has been supporting the flange portion 13 on the other side of the blister product 11 in the first zone 31 until then. It was decided. Thereby, each blister product 11 which moved to the 2nd zone 32 is tilted so that it may fall down. And by the said inclination, a height difference is derived | led-out between the flange parts 13 of the blister product 11 which adjoins. Therefore, problems such as the flanges 13 abutting against each other at the time of width adjustment in the next third zone 33 hardly occur. Also, the intended superposition mode can be realized relatively easily. That is, as in the present embodiment, by aligning the inclination direction, it is possible to align the superposition mode (the superposition does not become disjoint), and it is possible to improve the appearance when boxed, and such “alignment” Can be easily realized by setting the shape of the groove 32 as in the second zone 32.

  In addition, in this embodiment, in the fourth zone 34, each blister product 11 that has been tilted until then is brought close to a horizontal state. Accordingly, it is possible to improve the convenience and handleability when sucked by the suction moving means 51 thereafter, and to increase the certainty of suction.

  In addition, in the present embodiment, the above-described superposition can be realized by the single rail block 22. The increase in the number of parts and cost can be suppressed, and the configuration can be simplified.

  In addition, you may implement as follows, for example, without being limited to the description content of embodiment mentioned above.

  (A) In the embodiment described above, the five groove portions 23 are formed in the rail block 22 and the first to fourth zones 31 to 34 are provided to incline the blister product 11 and realize the overlapping of the flange portions 13. However, this is merely an example, and other methods may be used.

  (B) The blister product 11 may be superposed without being inclined. As an example, the configuration shown in FIG. 9 can be considered. In the example shown in the drawing, the blister product 11 is slid on the three sets of rails 61 to 63, and the guide rails in which both sides of the three blister products 11 are provided on both sides of the three sets of rails 61 to 63 are shown. 64 and 65 to be guided. And as shown in FIG.9 (b), while the height of each rail 61-63 is mutually different from the middle, the space | interval between rails 61-63 and the space | interval between guide rails 64 and 65 along a transfer direction. As shown in FIG. 9C, the three blister products 11 are finally set to the same height. In this way, the flange portions 13 may be overlapped with each other.

  (C) As a configuration for inclining the blister product 11, in the above-described embodiment, a configuration in which one side of the flange portion 13 is not supported is adopted, but another method may be adopted. For example, while providing the contact means which can contact | abut to the upper surface of one side part among the flange parts 13 of each blister product 11, the height of the said contact means is lower on the downstream side than the upstream side along the transfer direction. By forming, each blister product 11 can be configured to tilt with the transfer. By adopting such a configuration, the blister product 11 can be tilted more reliably. Moreover, it is good also as tilting so that one side may be lifted with the pusher which is not shown in figure.

  (D) It is good also as a structure which does not provide the adsorption | suction movement means 51 in the said embodiment. For example, each blister product 11 may be accommodated by being pushed into the box 18 as it is from the fourth zone 34 with the push pin 24.

  (E) In the above embodiment, the blister product 11 is embodied when boxed, but the configuration is not necessarily limited to being housed in the box 18. For example, the present invention may be embodied in the case of being packed in a form such as bagging, band tying, or pillow packaging.

  (F) The form of the blister product 11 is not necessarily limited to that of the above embodiment. That is, what is necessary is just to have at least a pocket part and the flange part formed in the circumference | surroundings, for example, it is good also as integrating blister products which comprise two or more pocket parts.
