Description

  The present invention relates to a transport system for transporting tires (particularly raw tires).

  Conventionally, a conveyance system for conveying a tire (particularly, a raw tire before vulcanization) is known. For example, Patent Document 1 discloses a transfer device that transfers a tire in a state where the inner diameter of the tire is supported by a hook as a device for transferring a raw tire.

Japanese Patent No. 5082437

  In a conventional raw tire transfer device, the raw tire may be damaged during the transfer (for example, the surface of the raw tire may be damaged). Moreover, in the conventional raw tire transfer device, since the raw tires can be transported only one by one, the transport efficiency of the raw tires is poor.

  The subject of this invention is improving the conveyance efficiency of a raw tire, suppressing the damage during a conveyance in a conveyance system which conveys a raw tire.

Hereinafter, a plurality of modes will be described as means for solving the problems. These aspects can be arbitrarily combined as necessary.
A raw tire transport system according to an aspect of the present invention includes a stacking device and a transport device. The stacking device is a device for stacking containers. The container has a placement member and a side wall. The mounting member has a first surface on which the raw tire is mounted. The side wall of the side wall is positioned higher than the upper surface of the green tire placed on the first surface, and when another container is placed on the upper end, the bottom of the other container is placed on the first surface. It is provided upright from the placing member so as to be higher than the upper surface of the placed raw tire. Further, the side wall forms a storage space for storing the raw tire together with the first surface.
The stacking device lifts one container and places the second surface of the one container on the upper end of the side wall of the other container that is directly below the one container. Stack the containers in the height direction. The second surface is a surface opposite to the first surface of the placement member of one container. The transport device transports one container or a plurality of containers stacked in the height direction.

When the container has the above-described configuration, the raw tire to be transported can be stored in the storage space of the container. Moreover, the storage space of the container is formed by a mounting member and a side wall whose upper end is higher than the height position of the raw tire when it is mounted on the mounting member. Thereby, the green tire stored in the storage space can be protected by the mounting member and the side wall of the container.
Furthermore, since the containers can be stacked in the height direction as described above, the number of containers that can be transported by the raw tire transport device can be increased. As a result, the conveyance efficiency in the raw tire conveyance system can be improved.

  The stacking apparatus may have a gripping part that grips the container by supporting the protruding part of the container that is circular in a plan view and has a protruding part on the side wall from the lower side. Thereby, the stacking apparatus can hold the container in a state where the raw tire is stored in the container.

The raw tire conveyance system may further include a stopper and a detector. The stopper is disposed at a predetermined position on the conveyance path of the container of the conveyance device, and stops the container conveyed by the conveyance device at the predetermined position. The detector detects that the container is stopped at the predetermined position.
In this case, when the detection unit detects one container stopped at a predetermined position, the stacking device lifts the one container, and then the other container that is transported to the predetermined position and stopped by the stopper. One container is stacked in the height direction on the other container by placing the second surface of the one container on the upper end of the side wall of the container.
Thereby, the container stacking operation can be executed at a predetermined position on the transport path of the transport device.

The raw tire conveyance system may further include a transfer device. The transfer device transfers the raw tire supplied from the supply unit that supplies the raw tire to the uppermost container among the plurality of containers stacked in the height direction.
Thereby, a raw tire can be transferred to the uppermost stacked container, and the conveyance of the raw tire can be executed efficiently.

  It can suppress that a raw tire is damaged during conveyance.

The raw tire transport system 100 includes a transport device 1. The conveying apparatus 1 is an apparatus that conveys an article such as a conveyor that conveys the container C in the conveying direction (for example, the direction indicated by the thick arrow in FIG. 1).

  As shown in FIG. 1, the transport device 1 of the present embodiment includes a first transport device 11, a second transport device 13, and a third transport device 15. The 1st conveyance apparatus 11 conveys the container C which accommodated the raw tire T to the stacking apparatus 2 (after-mentioned). The second transport device 13 can produce a plurality of containers C stacked in the height direction in the stacking device 2 or one container C in which other containers C are not stacked, for example, next production of tires. It is transported to a place (not shown) where the process is performed.

  The 3rd conveying apparatus 15 receives the container C which accommodated the raw tire T conveyed from the 1st conveying apparatus 11, and the other container C which accommodated the raw tire T in the stacking apparatus 2 as needed. Then, the container C (that is, the plurality of containers C stacked in the height direction) containing the raw tire T on which the other container C is stacked is sent to the second transport device 13. . In addition, the 3rd conveying apparatus 15 may send out the container C which accommodated the raw tire T to the 2nd conveying apparatus 13, without performing stacking operation | movement based on a user's instruction | indication.

  The raw tire transport system 100 includes a stacking device 2. The stacking device 2 is provided so as to correspond to the first position P1 where the third conveying device 15 is provided, and raises or lowers the container C in which the raw tire T is accommodated at the first position P1. Device. The configuration and operation of the stacking apparatus 2 of the present embodiment will be described in detail later.

  The raw tire transport system 100 includes a stopper 3. The stopper 3 stops the container C that has been transported to the third transport device 15 by the first transport device 11 at a first position P1 (an example of a predetermined position) on the transport path of the third transport device 15. It is a member. In the present embodiment, as shown in FIG. 1, the stopper 3 has a first stopper 31.

The first stopper 31 includes a pair of pin members 311 disposed between the third transport device 15 and the second transport device 13. As shown in FIG. 2, the first stopper 31 projects a pair of pin members 311 along a conveyance path between the third conveyance device 15 and the second conveyance device 13, and causes the pair of pin members 311 to have a container C. The container C can be stopped at the first position P1 by contacting the front side wall C2.

Part or all of the control of these components of the raw tire conveyance system 100 may be realized by a program that can be executed by a computer system that constitutes the controller 4. Moreover, a part of control of these components of the raw tire conveyance system 100 may be realized in hardware by SoC (System On Chip) or the like.

(2) Structure of Raw Tire Next, the structure of the raw tire T that is a conveyance target in the present embodiment will be described with reference to FIG. FIG. 3 is a view showing the structure of the green tire. As shown in FIG. 3, the green tire T is a rubber hollow member provided with a center hole.

(3) Container Structure Next, the structure of the container C that stores and transports the raw tire T will be described with reference to FIGS. 4 and 5. FIG. 4 is a diagram showing the structure of an empty container. FIG. 5 is a diagram illustrating an example of a state in which a raw tire is stored in a container.
The container C has a mounting member C1. The mounting member C1 is, for example, a cylindrical plastic member having a predetermined thickness and serves as the bottom of the container C. The mounting member C1 is formed with a tapered opening having a diameter that decreases from the upper surface side toward the lower surface (bottom surface) side. As shown in FIG. 5, the raw tire T is formed on the surface of the tapered opening. Is placed. The surface of the tapered opening on which the raw tire T is placed is referred to as “first surface C11”.

  On the other hand, the bottom surface of the mounting member C1 (that is, the surface opposite to the first surface C11 of the mounting member C1) is when the container C is stacked on another container C as shown in FIG. And placed on the upper end of the side wall C2 of the other container C. The bottom surface of the mounting member C1 that is mounted on the upper end of the side wall C2 of the other container C when the other container C is stacked will be referred to as a “second surface C12”.

As shown in FIGS. 4 and 5, the second surface C12 is provided with a protrusion C13 having a diameter smaller than the inner diameter of the side wall C2, concentrically with the second surface C12. The protrusion C13 prevents the container C from excessively moving in the lateral direction with respect to the other container C when the second surface C12 is placed on the upper end of the side wall C2 of the other container C.
The protrusion C13 is not limited to a form in which the entire portion other than the second surface C12 on the bottom surface of the mounting member C1 as shown in FIGS. 4 and 5 is projected, and is thin along the contour of the inner diameter of the second surface C12. The form which protrudes may be sufficient. In this case, the thin protrusion C13 may protrude over the entire outline of the second surface C12, or may protrude over a part of the outline.

  The tapered opening forming the first surface C11 may or may not penetrate the mounting member C1 as shown in FIGS. 4 and 5.

The container C has a side wall C2. The side wall C2 is, for example, a cylindrical plastic member having the same outer peripheral diameter as the mounting member C1 and having both ends opened. One open end of the cylindrical side wall C2 is fixed to the upper surface of the mounting member C1. That is, the side wall C2 is fixed to the mounting member C1 while standing upright from the mounting member C1. Accordingly, the container C constituted by the placement member C1 and the side wall C2 has a circular shape in plan view.
On the other hand, when the other container C is stacked on the other open end of the side wall C2, the second surface C12 of the other container C is placed. That is, the other open end of the side wall C2 becomes the upper end of the side wall C2 on which the second surface C12 of the other container C is placed.

  As shown in FIG. 5, the inner diameter of the cylindrical side wall C <b> 2 is larger than the outer diameter of the raw tire T. Further, as shown in FIG. 5, the height of the side wall C2 is such that the upper end of the side wall C2 is higher than the upper surface of the raw tire T placed on the first surface C11, and the side wall C2 It is designed such that when the container C is placed, the bottom (projection C13) of the other container C exists at a position higher than the upper surface of the raw tire T placed on the first surface C11. Thereby, the side wall C2 (inside thereof) forms a storage space for storing the raw tire T together with the first surface C11 formed on the mounting member C1. Further, the side wall C2 is designed to have the above height, so that when the containers C storing the raw tires T are stacked, the raw tires T stored in the containers C come into contact with other containers C. By avoiding the damage, the raw tire T can be prevented from being damaged.

  As described above, by allowing the raw tire T to be stored in the storage space formed by the side wall C2 and the first surface C11 of the container C, the container C is made of the raw tire T by the mounting member C1 and the side wall C2. Can be protected from the outside.

FIG. 5 shows that the upper end of the side wall C2 is higher than the upper surface of the raw tire T placed on the first surface C11, that is, the height of the side wall C2 is increased to deepen the container C. As shown, even when the raw tire T is stored in the container C, another container C can be stacked on the upper end of the side wall C2 of the container C.
Thereby, the number of the containers C which can be conveyed at once by the conveying apparatus 1 can be increased. As a result, the conveyance efficiency in the raw tire conveyance system 100 can be improved.

  As shown in FIGS. 4 and 5, a flange-like protrusion C <b> 21 is provided at the upper end of the side wall C <b> 2 along the outer periphery of the side wall C <b> 2 (the upper end thereof). As will be described later, when the container C is raised or lowered by the stacking device 2, in order to grip the container C by the stacking device 2, the lower side of the protrusion C <b> 21 is a gripping portion of the stacking device 2. 21 (described later) hook 211 (described later).

(4) Configuration of Stacking Device Next, the configuration of the stacking device 2 of the present embodiment will be described with reference to FIGS. 6A and 6B. FIG. 6A is a view of the stacking device as viewed from the container conveyance direction. FIG. 6B is a diagram schematically illustrating a state where the container is gripped by the hook 211. As illustrated in FIG. 6A, the stacking device 2 includes a grip portion 21, an elevating device 23, and a detector 25.
The gripping part 21 grips the container C at the first position P1. The gripping part 21 has a pair of hooks 211 that can move in the horizontal direction by driving a motor, for example, and can enlarge or reduce the distance between them.

Each of the pair of hooks 211 has a U-shape when viewed from above, as shown in FIG. 6B. The gripping portion 21 supports the container C by supporting the container C at four points by bringing the U-shaped bifurcated tip portions of the pair of hooks 211 into contact with the lower surface of the protruding portion C21 of the container C. Hold it.
The shape of the hook 211 is not limited to the above, and can be any shape that can hold the container C (the protruding portion C21 thereof).

  As another embodiment, the grip portion 21 may be attached to the lower end side of the grip portion 21 and may include a sensor 213 that detects whether or not the container C exists at a position where the grip portion 21 can grip. Good. Thereby, the gripper 21 can grip the container C after confirming that the container C is in a position where it can be securely gripped by the gripper 21.

  The lifting device 23 is fixed to the mounting member 27 immediately above the third transport device 15 (that is, directly above the first position P1). For example, the elevating device 23 raises or lowers the gripping portion 21 at the first position P1 by winding or sending the suspension member 231 having a lower end fixed to the gripping portion 21 by driving a motor or the like.

  The detector 25 is mounted on a side surface of the support member 29 that supports the mounting member 27 of the lifting device 23 at a position higher than the transport surface of the container C of the third transport device 15. The detector 25 detects whether or not the container C exists at the first position P1. As the detector 25, for example, a light emitting / receiving sensor (photoelectric sensor) can be used. When a light emitting / receiving sensor is used as the detector 25, if light reflected by the side wall C2 of the container C is detected, it is determined that the container C exists at the first position P1.

(5) Operation of Raw Tire Transport System Hereinafter, the transport operation of the container C and the transfer and transport operation of the raw tire T in the raw tire transport system 100 will be described. In the raw tire transport system 100 according to the first embodiment, the transport of the container C to the first position P1 and the stacking of the container C that has reached the first position P1 on another container are performed. .
When the detector 35 detects that the container C in which the raw tire T is stored has been transported toward the first position P1 by the first transport device 11, the controller 4 detects the first position P1 as necessary. The container C conveyed to the other container C is stacked.

  When the container C that has been transported to the first position P <b> 1 is stacked on another container C, the controller 4 has a pair of first stoppers 31 disposed between the third transport device 15 and the second transport device 13. The pin member 311 is protruded at the position. Accordingly, the container C transported from the first transport device 11 to the third transport device 15 is stopped by the pair of pin members 311.

  After stopping the container C at the first position P1, the controller 4 instructs the stacking device 2 to lift the container C by grasping and raising the container C at the first position P1 ( FIG. 7A, FIG. 7B). Then, the conveyance of the container C by the conveying apparatus 1 is restarted in the state where the container C is lifted at the first position P1.

  Thereafter, when another container C for stacking containers C held by the stacking device 2 is transported to the first position P1, another container transported to the first position P1 by the pin member 311. C stops at the first position P1, as shown in FIG. 7C. If the pin member 311 is lowered when another container C is being transported to the first position P1 while the container C is lifted at the first position P1, the controller 4 The member 311 may protrude again.

In a state where the other container C is stopped at the first position P1, the controller 4 makes the second surface C12 of the container C gripped by the grip portion 21 with respect to the stacking device 2 be at the first position P1. The container C is instructed to be lowered at the first position P1 until the upper end of the side wall C2 of the other container C stopped at is reached (FIG. 7D).
In this way, the stacking device 2 is placed on the upper end of the side wall C2 of the other container C existing at the first position P1 directly below the one container C gripped by the grip portion 21. The second surface C12 of the mounting member C1 can be mounted, and the one container C that has been gripped can be stacked in the height direction on the other container C present at the first position P1.

After the container C is stacked on another container C, as shown in FIG. 7E, the gripping of the container C by the hook 211 of the gripping part 21 is released, and the stacking of the plurality of containers C is completed.
After releasing the grasping of the container C, the pin member 311 is lowered, and a plurality of (two) containers C after stacking are sent out to the second transport device 13 by the third transport device 15, The plurality of containers C are transported by the second transport device 13 toward the second position P2.

As described above, the raw tire transport system 100 according to the first embodiment efficiently performs the stacking operation of the container C for transporting the raw tire T and the transfer of the raw tire T to the container C. Can be executed.
Further, the height of the side wall C2 of the container C is higher than the upper surface of the raw tire T placed on the first surface C11, and another container C is placed on the upper end of the side wall C2. The bottom portion (protrusion C13) of the other container C is placed at a height higher than the top surface of the raw tire T placed on the first surface C11 when placed, so that the raw tire T is stored. When the stacked containers C are stacked, it is possible to prevent the raw tire T accommodated in the container C from coming into contact with another container C and prevent the raw tire T from being damaged.
