Description

  The present invention relates to a container manufacturing method and a manufacturing system.

  For example, in convenience stores, containers filled with beverages such as plastic bottles are placed on the display device in a vertical position and sold. And such a display apparatus is arrange | positioned in the state inclined, for example so that a container might move ahead of a display case with dead weight of the container itself. When one container on the near side (front row) is extracted, the subsequent container moves to the near side by its own weight.

  Here, a plastic flat plate, for example, is provided at a place where the container of the display device is placed because of the good sliding property of the container. In recent years, a display device in which a large number of rotatable rollers are arranged has been proposed (for example, see Patent Document 1). In addition, the container is generally refilled from the rear side of the display device, but the container can be loaded from the front side, and the container moved to the back side is moved to the front side again and displayed. A display device has also been proposed (see, for example, Patent Document 2). That is, a display device has been proposed in which a container thrown in from the front side makes a U-turn and returns. Further, as a container, a can has been proposed in which inner concave portions and vertical ribs are alternately formed in the circumferential direction on the inner peripheral wall of an annular convex portion formed on the can bottom (see, for example, Patent Document 3). ).

Here, in the present embodiment, the first pin 521 is disposed on the most upstream side in the movement direction of the container 20, and the sixth pin 526 is disposed on the most downstream side in the movement direction. In addition, each of the first pin 521 to the sixth pin 526 is arranged with a certain gap. The rotation mechanism 50 includes a fixing member 53 that fixes the rod-like member 51 to the guide 32 on the right side.

  Moreover, as shown to the same figure (B), the inclination which leaves | separates from the mounting part 31 is provided to the rod-shaped member 51 as it goes ahead. For this reason, in the present embodiment, the first pin 521 is disposed closest to the placement unit 31, and the sixth pin 526 is located at a position farthest from the placement unit 31. In other words, the positions of the first pin 521 to the sixth pin 526 are shifted from each other in the height direction. In this figure, for easy understanding, the inclination of the rod-like member 51 is displayed larger than the actual inclination.

  The fixing member 53 in the present embodiment is inserted into the right side guide 32 and is slidable with respect to the right side guide 32. For this reason, in the display device 30 according to the present embodiment, the first pin 521 to the sixth pin 526 can be moved in the height direction by sliding the fixing member 53 with respect to the guide 32 on the right side. Yes. In the present embodiment, a screw 54 for positioning the fixing member 53 on the right guide 32 is provided.

Further, the fixing member 53 is pressed and fixed to the inner wall of the hole 32 </ b> A by a screw 54.

Next, the container 20 will be described.
4 and 5 are diagrams for explaining the container 20. 4A shows a front view of the container 20, and FIG. 4B shows a left side view of the container 20. FIG. 5A shows a rear view of the container 20, and FIG. 5B shows a right side view of the container 20. FIG. 4A, 4B, 5A, and 5B are cross-sectional views taken along the line AA.

The container 20 in this embodiment has illustrated the container formed with resin materials, such as PET (polyethylene terephthalate). For example, such a container 20 can be manufactured by an injection molding (blow molding) method using a resin material or a blow molding method after forming a preform using a resin material.
As shown in FIG. 4 (A), the container 20 in the present embodiment has a container body 21 having an opening (a drinking mouth) in the upper part and formed in a cylindrical shape and filled with a beverage therein, and an opening of the container body 21. And a cap 22 for closing the cover. A film F is attached to the outer peripheral surface of the container body 21. In addition, the container main body 21 has a diameter on the upper side smaller than a diameter on the bottom side. That is, the container main body 21 is in a state where the diameter of the upper side is reduced. And in this embodiment, the 2nd protrusion part 25 mentioned later is provided with respect to this reduced diameter part (reduced diameter part).

Here, on the film F, as shown in FIG. 5A, an identification mark 23 for distinguishing it from other products such as a product name and a trade name is printed.
In addition, the container 20 includes a first protrusion 24 that protrudes in an annular shape in the radial direction of the container main body 21 from the outer peripheral surface of the container main body 21 at the upper part of the container main body 21 (under the cap 22). Here, the first protrusion 24 is formed integrally with the container body 21.

  Further, the container 20 includes a second protrusion 25 as an example of a rotating part below the first protrusion 24. Here, the protruding amount of the second protruding portion 25 is smaller than the protruding amount of the first protruding portion 24. In this case, compared to the case where the second protrusion 25 protrudes from the first protrusion 24, the user's fingers when operating the cap 22 are less likely to be caught by the second protrusion 25. Further, as shown in the sectional view of FIG. 4A, the second protrusion 25 is wound around the container body 21 from the side where the identification mark 23 is provided to the side opposite to the side where the identification mark 23 is provided. It is provided to attach. In other words, it is provided along the clockwise direction from the side where the identification mark 23 is provided to the opposite side. More specifically, the second protrusion 25 is provided within a predetermined range in the circumferential direction of the container body 21.

  More specifically, when the container 20 is viewed from the side where the identification mark 23 is provided (see FIG. 4A), the container 20 is provided with the second protrusion 25 on the right side surface side. It has no configuration. In addition, at the position in the height direction at which the second protrusion 25 is provided, the right side of the container 20 (the region adjacent to the second protrusion 25) is in a state where the container body 21 is exposed. Yes. More specifically, it is a tangent to the right side surface of the container body 21 and a tangent line from the front side to the back side of the container 20 and passes through the height position where the second projecting portion 25 is provided (of FIG. 4A). The second protrusion 25 is not provided on the right side of the container 20 from the cross-sectional view).

  Moreover, the 2nd protrusion part 25 has the structure in which the lower surface was formed in step shape, and was provided with the several step part. If it demonstrates in detail, the lower surface of the 2nd protrusion part 25 is formed in the step shape so that height may reduce as it goes clockwise. For this reason, the 2nd protrusion part 25 in this embodiment is the structure provided with the 1st flat surface 251-the 6th flat surface 256 from which the position in a height direction differs in the lower part. In addition, the second projecting portion 25 has a plurality of end faces whose positions in the height direction are different from each other and whose positions in the circumferential direction of the container body 21 are different from each other.

  Here, each of the 1st flat surface 251-the 6th flat surface 256 crosses with the outer peripheral surface of the container main body 21, as shown in sectional drawing of FIG. 4 (A) (substantially orthogonal relationship). Has been placed. The first flat surface 251 is located on the side where the identification mark 23 is provided, as shown in FIG. In addition, the identification mark 23 is located below the first flat surface 251. Further, as shown in FIG. 5A, the sixth flat surface 256 is located on the side opposite to the side on which the identification mark 23 is provided. In addition, the second flat surface 252 to the fifth flat surface 255 are directed from the first flat surface 251 toward the sixth flat surface 256, the second flat surface 252, the third flat surface 253, the fourth flat surface 254, and the fifth flat surface 255. The flat surfaces 255 are provided in this order. Further, in the circumferential direction of the container 20, the first flat surface 251 to the sixth flat surface 256 are provided at predetermined angles. In addition, the first flat surface 251 is located at the bottom and the sixth flat surface 256 is located at the top.

  The second protrusion 25 and first to fifth protrusions 241 to 245 described later can be formed when the container 20 is formed. Further, for example, a member such as a resin piece or a metal piece may be separately attached or the like.

Next, the operation of the container 20 in the display device 30 will be described.
FIG. 6 is a view for explaining the operation of the container 20 in the display device 30. In the drawing, the first roller row 312, the second roller row 313, and the fixing member 53 are not shown. In order to make the drawing easier to see, the first pin 521 to the sixth pin 526 are displayed above the first protrusion 24.
As indicated by reference numeral 5A in the figure, when the container 20 is inserted into the display device 30 with the identification mark 23 facing obliquely forward to the right, the first flat surface 251 comes into contact with the first pin 521. . As a result, a rotational force (drag) is applied to the container 20, and the container 20 rotates counterclockwise. Next, as the container 20 moves forward, the second flat surface 252 abuts against the second pin 522 (see reference numeral 5B), and the container 20 similarly rotates counterclockwise.

  After that, the container 20 has a circumferential direction in which the third flat surface 253 hits the third pin 523, the fourth flat surface 254 hits the fourth pin 524, and the fifth flat surface 255 hits the fifth pin 525. Rotate sequentially. Finally, the sixth flat surface 256 abuts against the sixth pin 526 (see reference numeral 5C), so that the identification mark 23 faces forward. Thereafter, the container 20 slides on the placement unit 31 and reaches the front of the display device 30.

  In the present embodiment, the identification mark 23 and the region provided with the second protrusion 25 (the first flat surface 251 to the sixth flat surface 256) are arranged with a predetermined positional relationship. The area where the identification mark 23 and the second projecting portion 25 are not provided is also arranged with a predetermined positional relationship. Specifically, when the identification mark 23 is oriented in one direction, the region where the second projecting portion 25 is not provided is oriented in a direction orthogonal to the one direction.

  For this reason, in the present embodiment, the container 20 rotates when the identification mark 23 faces in a direction other than the front, and the container 20 does not rotate when the identification mark 23 faces the front. In addition, even if the container 20 is loaded while the identification mark 23 is not facing forward, when the container 20 reaches the front side of the display device 30, the identification mark 23 is directed forward. In other words, in the present embodiment, the identification mark 23 faces forward even if the thrower who puts the container 20 into the display device 30 does not perform a special operation.

  Although not described above, the positions of the first pin 521 to the sixth pin 526 are adjusted in advance in the height direction. That is, the third pin 523 and the third flat surface 253 are abutted so that the second pin 522 and the second flat surface 252 are abutted so that the first pin 521 and the first flat surface 251 are abutted. The positions of the first pin 521 to the third pin 523 are adjusted in advance in the height direction. Further, the sixth pin 526 and the sixth flat surface 256 are abutted so that the fifth pin 525 and the fifth flat surface 255 are abutted so that the fourth pin 524 and the fourth flat surface 254 are abutted. The positions of the fourth pin 524 to the sixth pin 526 are adjusted in advance in the height direction.

Next, another example of the operation of the container 20 will be described.
7 and 8 are diagrams showing another operation example of the container 20.
As shown in FIG. 7A, when the container 20 is loaded with the identification mark 23 facing the rear side of the display device 30, the third flat surface 253 is facing the front of the display device 30. . The container 20 moves forward, but the third flat surface 253 passes above the first pin 521 and the second pin 522 (see also FIG. 2B). For this reason, the container 20 reaches the third pin 523 without rotating. The container 20 receives rotational force from the third pin 523 and rotates in the same manner as described above. Then, the container 20 reaches the front of the display device 30 with the identification mark 23 facing forward as in the above.

  For example, as shown in FIG. 7B, when the container 20 is loaded with the identification mark 23 facing diagonally to the left, the sixth flat surface 256 faces the front of the display device 30. The container 20 moves forward, but the sixth flat surface 256 passes over the first pin 521 to the fifth pin 525 (see also FIG. 2B). For this reason, the container 20 reaches the sixth pin 526 without rotating. The container 20 receives a rotational force from the sixth pin 526 and rotates in the same manner as described above. Then, the container 20 reaches the front of the display device 30 with the identification mark 23 facing forward as in the above.

  Further, as shown in FIG. 8, for example, the container 20 may be loaded with the identification mark 23 facing forward. In this case, the second projecting portion 25 does not exist on the side surface of the container 20 that faces the side where the first pin 521 to the sixth pin 526 are disposed. In other words, the region (surface) where the second projecting portion 25 does not exist and the side where the first pin 521 to the sixth pin 526 are arranged face each other. In other words, the first flat surface 251 to the sixth flat surface 256 that abut against the first pin 521 to the sixth pin 526 are not positioned on the right side surface side of the container 20 in the drawing. For this reason, the container 20 reaches the front of the display device 30 without rotating. That is, it reaches the front of the display device 30 while maintaining the state where the identification mark 23 faces forward.

  Here, the operation when one container 20 is loaded has been described above. However, when a plurality of containers 20 are already displayed on the display device 30, when the container 20 located at the top is taken out, A space is formed by the amount of the container 20. And the 2nd container 20 comes to move toward this space. The movement of the container 20 following the second container 20 is also started. At this time, each container 20 is rotated by the first pin 521 to the sixth pin 526 so that the identification mark 23 of each container 20 faces frontward.

The container 20 can have the following form.
9 and 10 are diagrams showing a modification of the container 20. 9A shows a front view of the container 20, and FIG. 9B shows a left side view of the container 20. FIG. FIG. 10A shows a rear view of the container 20, and FIG. 10B shows a right side view of the container 20. 9A, 9B, 10A, and 10B are cross-sectional views taken along line AA.

  In the container 20 in this modification, two identification marks 23 are provided. That is, the first identification mark 23a and the second identification mark 23b are provided. Here, the first identification mark 23a and the second identification mark 23b are out of phase by 180 ° in the circumferential direction of the container 20. In other words, the second identification mark 23b is provided on the side opposite to the side where the first identification mark 23a is provided.

  Moreover, in the container 20 in this modified example, the two 2nd protrusion parts 25 are in the state provided. Specifically, one second protrusion 25 is provided above the first identification mark 23a, and the other second protrusion 25 is provided above the second identification mark 23b. More specifically, the second protrusion 25 is not provided at a position where the phase is shifted by 90 ° with respect to the first identification mark 23a and the second identification mark 23b. In addition, each of the 2nd protrusion part 25 is provided with the 1st flat surface 251-the 3rd flat surface 253 in the lower part like the above in which the lower surface is formed in step shape.

Next, the operation of the container 20 in the display device 30 will be described.
FIG. 11 is a view for explaining the operation of the container 20 in the display device 30.
As shown in FIG. 11A, for example, when the container 20 is loaded with the first identification mark 23a facing diagonally left rearward of the display device 30, the first of the two second protrusions 25 The first flat surface 251 in the two projecting portions 25 faces the front of the display device 30. The container 20 moves forward. At this time, the first flat surface 251 comes into contact with the first pin 521. As a result, the container 20 rotates counterclockwise. Thereafter, the second flat surface 252 hits the second pin 522, and the container 20 further rotates. Further, the third flat surface 253 hits the third pin 523, and the container 20 further rotates. As a result, the first identification mark 23a faces forward.

  11B, for example, when the container 20 is loaded with the second identification mark 23b facing diagonally to the left of the display device 30, the other of the two second protrusions 25 The first flat surface 251 in the second projecting portion 25 is directed to the front of the display device 30.

The transport device 600 transports the container body 21 via the rotating device 700 and the film mounting device 800 using a rotating roller 620 rotated by a motor (not shown).
The rotating device 700 rotates the container main body 21 in the circumferential direction so that the container main body 21 has a predetermined posture.
Moreover, the film mounting apparatus 800 mounts the film F on the container main body 21 by covering the container main body 21 with the film F from above, for example. In addition, the container main body 21 with the film F attached is conveyed to a heating process (not shown). In this heating step, the film F contracts and the film F is fixed to the outer peripheral surface of the container body 21.

Next, the rotating device 700 will be described in detail.
FIG. 18 is a top view of the rotating device 700. FIG. 19 is a right side view of the rotating device 700.

  Here, although not described above, a plurality of rotation rollers 620 of the transport device 600 are provided in the transport direction of the container body 21 and a plurality (three in this embodiment (three rows) in the width direction of the base 610).

That is, as shown in FIG. 18, the rotating device 700 is provided along the movement path of the container body 21 and above the base 610, and the movement path of the container body 21 attached to the rod member 71. A first pin 721 to a sixth pin 726 are provided as an example of a protruding portion protruding upward (on the conveyance path).

  Here, also in the rotating device 700, the first pin 721 is disposed on the most upstream side in the movement direction of the container 20, and the sixth pin 726 is disposed on the most downstream side in the movement direction. The rotating device 700 includes a fixing member (not shown) that fixes the rod-like member 71 to a device frame (not shown). In addition, by providing the rod-like member 71 so as to be movable in the vertical direction, the first pin 721 to the sixth pin 726 are arranged at the height of the rotating device 700 in the same manner as the first pin 521 to the sixth pin 526 shown in FIG. Can be moved in the direction. In this case, the container main bodies 21 having different sizes (different positions of the second protrusions 25) can also be rotated.

  In addition, as shown in FIG. 19, the rod-like member 71 is inclined so as to move away from the base 610 toward the front. For this reason, the first pin 721 is disposed closest to the base 610, and the sixth pin 726 is located at a position farthest from the base 610. In other words, the positions of the first pin 721 to the sixth pin 726 are shifted from each other in the height direction. Also in this figure, for easy understanding, the inclination of the rod-like member 71 is displayed larger than the actual inclination.

  As shown in FIG. 18, the rotating device 700 includes a fall prevention mechanism 730 that prevents the fall of the container body 21 that may occur when the container body 21 contacts the first pin 721 to the sixth pin 726. . The fall prevention mechanism 730 includes a first member 731 that moves from the upstream side in the movement direction of the container body 21 toward the downstream side in the movement direction, and a second member 732 that also moves from the upstream side in the movement direction toward the downstream side in the movement direction. And.

  The first member 731 is formed in an arc shape so as to follow the outer peripheral surface of the container main body 21. Specifically, it is formed by drawing an arc so as to protrude toward one side of the movement path of the container body 21. More specifically, the first member 731 has a shape that follows the outer circumferential surface of a semicircle. The second member 732 is also formed in an arc shape so as to follow the outer peripheral surface of the container body 21. Specifically, it is formed by drawing an arc so as to protrude toward the other side of the movement path of the container body 21. More specifically, the second member 732 has a shape that follows the outer circumferential surface of a semicircle.

  The first member 731 and the second member 732 as an example of the counter member are close to each other on the upstream side of the first pin 721 in the movement direction of the container body 21 and face each other. The first member 731 and the second member 732 face the outer peripheral surface of the container body 21 when they approach each other, and house the container body 21 therein. Thereafter, the first member 731 and the second member 732 move at the same speed as the moving speed of the container main body 21, and after the container main body 21 passes through the sixth pin 726, the first member 731 and the second member 732 move away from each other. If it adds, the 1st member 731 and the 2nd member 732 will move to the position which remove | deviated from the movement path | route of the container main body 21. FIG. Here, in this embodiment, since the container main body 21 is supported by the first member 731 and the second member 732, the container main body 21 that can be generated when the container main body 21 contacts the first pin 721 to the sixth pin 726. Falling is prevented.

  Thereafter, the first member 731 and the second member 732 move toward the upstream side in the movement direction of the container main body 21 to store a new container main body 21. That is, the first member 731 and the second member 732 are provided so as to be able to circulate, and repeat the movement of housing the container main body 21 and the movement of the container main body 21 upstream in the movement direction. A plurality of first members 731 and second members 732 are provided in the moving direction of the container body 21.

The operation of the container body 21 in the rotating device 700 will be further described.
FIG. 20 is a view showing the operation of the container main body 21 in the rotating device 700. In addition, illustration of the fall prevention mechanism 730 is abbreviate | omitted in this figure.
For example, when the container main body 21 is transported with the first flat surface 251 facing the downstream side in the transport direction of the container main body 21 as indicated by reference numeral 19A in the figure, the first flat surface with respect to the first pin 721. 251 comes to abut. Thereby, a rotational force is applied to the container body 21, and the container body 21 rotates counterclockwise. In other words, a drag force is applied to the first flat surface 251 from the downstream side in the transport direction of the container body 21 toward the upstream side in the transport direction, and the container body 21 rotates counterclockwise. Next, as the container body 21 moves forward, the second flat surface 252 abuts on the second pin 722 (see reference numeral 19B), and the container body 21 similarly rotates counterclockwise.

  Thereafter, the container main body 21 has a circumferential direction in which the third flat surface 253 hits the third pin 723, the fourth flat surface 254 hits the fourth pin 724, and the fifth flat surface 255 hits the fifth pin 725. Are sequentially rotated. Finally, the sixth flat surface 256 hits the sixth pin 726 (see reference numeral 19C).

  Accordingly, as indicated by reference numeral 19D, the first flat surface 251 is located on the downstream side in the transport direction of the container body 21, and the fifth flat surface 255 is located on the upstream side in the transport direction of the container body 21. Moreover, the area | region where the 2nd protrusion part 25 is not provided faces the side (side in which the 1st pin 721-the 6th pin 726 are provided) of the movement path | route. The container body 21 is conveyed to the film mounting apparatus 800 while maintaining this posture, and the film F is mounted on the film mounting apparatus 800 so that the identification mark 23 is positioned below the first flat surface 251. . In other words, the film F is mounted so that the second projecting portion 25 and the identification mark 23 have a predetermined positional relationship. Then, it is conveyed to a heating process and the film F is fixed to the container main body 21. Thereby, the container 20 shown in FIGS. 4 and 5 is completed.

For example, when the container main body 21 is transported with the third flat surface 253 facing the downstream side in the transport direction of the container main body 21, the container main body 21 rotates as shown in FIG. I do. Similarly to the above, the first flat surface 251 is located on the downstream side in the transport direction of the container body 21, and the fifth flat surface 255 is located on the upstream side in the transport direction of the container body 21.
Further, for example, when the container body 21 is transported with the sixth flat surface 256 facing the downstream side in the transport direction of the container body 21, the container body 21 rotates as shown in FIG. 7B. I do. Similarly to the above, the first flat surface 251 is located on the downstream side in the transport direction of the container body 21, and the fifth flat surface 255 is located on the upstream side in the transport direction of the container body 21.
Further, when the container body 21 is transported in a state where the first flat surface 251 is located on the downstream side in the transport direction of the container body 21, the container body 21 does not rotate as shown in FIG. Move while maintaining.
Although not described in detail, the container 20 shown in FIGS. 13 and 14 also performs the same operation as described above in the rotating device 700.

Next, the container 20 will be described.
FIG. 27 is a view for explaining the container 20. 2A is a front view of the container 20, and FIG. 2B is a bottom view of the container 20. FIG.
The container 20 in the present embodiment also exemplifies a container formed of a resin material such as PET (polyethylene terephthalate). For example, such a container 20 can be manufactured by an injection molding (blow molding) method using a resin material or a blow molding method after forming a preform using a resin material.

  Further, as shown in FIG. 6A, the container 20 in the present embodiment has an opening (drinking mouth) at the top and is formed in a cylindrical shape, and is filled with a drink, like the container 20 described above. The container body 21 and a cap 22 that closes the opening of the container body 21 are provided. A film F is attached to the outer peripheral surface of the container body 21. The film F is printed with an identification mark 23 for distinguishing it from other products such as product names and trade names.

The protruding portion 214 can be formed integrally with the container body 21 or can be formed by attaching another member by adhesion or the like.

Next, the operation of the container 20 in the display device 30 will be described.
FIG. 28 is a diagram illustrating the operation of the container 20 in the display device 30.
When the container 20 is placed on the rear side of the display device 30 as indicated by a solid line 28A in the figure, the annular protrusion 213 (see FIG. 27B) contacts the protrusion 913e. As a result, a load acts on the rotation stop mechanism 913 from the container 20, and the moving member 913d in the rotation stop mechanism 913 moves forward. At this time, the right side of the container 20 in the drawing tends to move smoothly forward by the first roller portion 911, but the left side in the drawing is given resistance from the resistance applying portion 912, so Movement is restricted.

As a result, as indicated by a broken line 28B, the container 20 rotates clockwise (circumferential direction) while moving forward. That is, the resistance force that resists the moving force that the container 20 tries to move forward varies depending on the portion of the container 20, and the container 20 rotates. Specifically, the left and right resistance forces are different from each other at the center of gravity of the container 20, and the container 20 rotates.
Thereafter, one protrusion 214 (see FIG. 27) of the container 20 abuts against the protrusion 913e of the rotation stop mechanism 913. In other words, the protrusion 913e and the one protrusion 214 face each other. Thereby, rotation of the container 20 is stopped (restricted) (see the broken line 28C). Here, the protruding portion 214 can be regarded as a rotation stopping portion that stops the rotation of the container 20 (container body 21). Thereafter, when the container 20 reaches a predetermined position of the second roller portion 914, the container 20 and the protrusion 913e are in a non-contact state. As a result, the container 20 is moved further forward by the second roller portion 914 (see the broken line 28D).

  Also in the present embodiment, even if the container 20 is placed on the placement unit 31 with the identification mark 23 facing rearward, the identification mark 23 is directed forward when reaching the front. For this reason, even if the container 20 is loaded while the identification mark 23 is not facing forward, the identification mark 23 is directed forward when the container 20 reaches the front side of the display device 30.

Next, the manufacturing process of the container 20 will be described.
