Summary of the Invention

Problems to be Solved by the Invention

[0005] The conveying device disclosed in Patent Document 1 has a stopper member attached to a roller. When the roller rotates, the stopper member takes a lying posture and a standing posture, and the object to be conveyed collides with the stopper member in the standing posture. When the stopper member stands up to stop the object to be conveyed, the object to be conveyed collides with the stopper member at a certain speed, so the object to be conveyed may be deformed or damaged. The present invention aims to provide a stopper unit that transports a plurality of conveyed objects, holds the plurality of conveyed objects at a fixed location, or temporarily stops the conveyed objects when transporting them to a branch path. Even when the conveyed objects are stopped by a stopper member, it is difficult for the conveyed objects to be deformed or damaged, and the mounting position can be easily changed.

Means for Solving the Problems

[0006] A first aspect of the present invention for solving the above problems is a stopper unit attached to a conveying device and provided with a stopping member that protrudes upward from the conveying device to stop a conveyed object, wherein a rotating member is provided adjacent to the stopping member.

[0007] According to this aspect, since it is a stopper unit attached to a conveying device and provided with a stopping member that protrudes upward from the conveying device to stop a conveyed object, and a rotating member is provided adjacent to the stopping member, the conveyed object can be smoothly conveyed by the rotating member until it is stopped by the stopping member.

[0008] This aspect is a stopper unit in which the rotating member is a unit-side roller that rotates freely.

[0009] According to this aspect, since the rotating member is a unit-side roller that rotates freely, the unit-side roller rotates freely. When the conveyed object approaches the stopping member, the speed of the conveyed object decreases, and the force when the conveyed object collides with the stopping member becomes smaller, making it difficult for the conveyed object to be deformed or damaged.

[0010] In this aspect, it is desirable that the power transmission member is a rotating body, and the rotating body is in contact with both the conveying roller and the unit-side roller.

[0011] According to this aspect, since the power transmission member is a rotating body that contacts both the conveying roller and the unit-side roller, the transmission power of the conveying roller can be reliably transmitted to the unit-side roller.

[0012] This aspect is preferably a stopper unit having pressing means for pressing the rotating body against both the conveying roller and the unit-side roller.

[0013] According to this aspect, since it is a stopper unit having pressing means for pressing the rotating body against both the conveying roller and the unit-side roller, the transmission power of the conveying roller can be more reliably transmitted to the unit-side roller by the pressing force.

[0014] This aspect is a stopper unit in which the conveying device has conveying rollers arranged at equal intervals, the conveying rollers have missing portions where the conveying rollers are missing, and the stopper unit is inserted into the missing portions.

[0015] According to this aspect, since the conveying device has conveying rollers arranged at equal intervals, the conveying rollers have missing portions where the conveying rollers are missing, and it is a stopper unit inserted into the missing portions, a missing portion can be set at a predetermined position, and the stopper unit can be inserted into the predetermined position.

[0016] This aspect is a conveying rotating member in which the rotating member contacts the conveyed object and moves the conveyed object, a plurality of rotating members are arranged in parallel, the conveying rotating member has a large-diameter portion and a small-diameter portion, and adjacent rotating members are in a state where the large-diameter portion of one rotating member enters the position of the small-diameter portion of the other rotating member, and it is preferably a stopper unit.

[0017] In this aspect, the stopping member is provided with a rack, and the stopping member is moved up and down via at least two gears. At least one gear is a driving gear rotated by power, and the other one is an intermediate gear rotated by receiving power directly or indirectly from the driving gear, which is a stopper unit.

[0018] According to this aspect, since the stopping member is provided with a rack and the stopping member is moved up and down via at least two gears, with at least one gear being a driving gear rotated by power and the other one being an intermediate gear rotated by receiving power directly or indirectly from the driving gear, which is a conveying device, the rotational movement of the gear can be changed into a linear movement by the rack to move the stopping member up and down. Also, by providing an intermediate gear smaller than the driving gear, it becomes possible even with a short stopping member, and the stopper unit can be made more compact.

[0019] In this aspect, the stopping member is provided with a rack and is a stopper unit that moves the stopping member up and down via at least one gear.

[0020] Since this aspect is a stopper unit in which the stopping member is provided with a rack and the stopping member is moved up and down via at least one gear, the rotational movement of the gear can be changed into a linear movement by the rack to move the stopping member up and down.

[0021] Preferably, in this aspect, the stopping member has at least one protrusion, and the proximity sensor detects the protrusion to move the stopping member up and down, which is a stopper unit.

[0022] According to this aspect, since the stopping member has at least one protrusion, and the proximity sensor detects the protrusion to move the stopping member up and down, which is a stopper unit, the position of the stopping member can be detected, and the stopping member does not move up and down an unnecessary distance. Therefore, even with a short stopping member, it is possible to stop the conveyed object, and the stopper unit can be made more compact.

[0023] This aspect is a conveying device using the stopper unit of the present invention.

[0024] According to this aspect, since it is a conveying device using the stopper unit of the present invention, in particular, a plurality of rotating members are arranged in parallel, the conveying rotating member has a large-diameter portion and a small-diameter portion, and when the large-diameter portion of one conveying rotating member enters the position of the small-diameter portion of the adjacent conveying rotating member, the gap on the conveying surface is small, so small conveyed objects can be conveyed.

[0025] This aspect is a manufacturing method of a conveying device for adding a stopping member for stopping a conveyed object to a conveying device in which conveying rollers are arranged at equal intervals, the method including removing some of the conveying rollers from the conveying device to form a missing portion, and arranging a stopper unit in the missing portion.

[0026] According to this aspect, since it is a manufacturing method of a conveying device for adding a stopping member for stopping a conveyed object to a conveying device in which conveying rollers are arranged at equal intervals, the method including removing some of the conveying rollers from the conveying device to form a missing portion, and arranging a stopper unit in the missing portion, it is possible to remove the conveying rollers at the location where the conveyed object is to be stopped, and after removing the conveying rollers, the stopper unit can be incorporated. Even after the conveying device starts operating, since the position of the stopper unit can be changed, the location where the conveyed object is stopped can be freely selected.

Advantages of the Invention

[0027] An object of the stopper unit of the present invention and a conveying device using the same is to provide a stopper unit and a conveying device using the same that are less likely to cause deformation or damage to the conveyed object even when the conveyed object is stopped by the stopper member, and are easy to change the mounting position.

Embodiments for Carrying Out the Invention

[0029] Hereinafter, the description will be made with reference to the drawings. FIG. 1 is a perspective view near the stopper unit 3 of the conveying device 1 incorporating the stopper unit 3 according to the present embodiment, showing a state where the stop member 4 is raised. FIG. 2 is a perspective view near the stopper unit 3 of the conveying device 1 incorporating the stopper unit 3 according to the present embodiment, showing a state where the stop member 4 is lowered. As shown in FIGS. 1 and 2, the conveying roller 10 is a known roller with a built-in motor, and the conveying roller 2 is rotated by transmitting power from the conveying roller 10 to the pulley 11 installed at the end of the conveying roller 2 and the belt 12 suspended from the pair of pulleys 11.

[0030] In this embodiment, the conveyed object is conveyed from the upstream side E of the conveying device 1 by the conveying roller 2 and is stopped by the stopping member 4 of the stopper unit 3 at an arbitrary position. The following cases can be considered for raising the stopping member 4. (1) Hold a plurality of conveyed objects at a fixed location, or temporarily stop the conveyed object when conveying the conveyed object to a branch path. (2) Align the orientation of the conveyed object with attachments. For example, attach a label. Read a barcode. Take out the conveyed object with a robot arm. An operator performs an operation of taking out an object contained in the conveyed object. Branch. etc. In such cases, align the orientation of the conveyed object so that each operation proceeds smoothly. (3) When the conveyed object is stagnant on the downstream side, raise the stopping member upstream to prevent collision between the conveyed objects. (4) Increase the conveying speed on the downstream side, raise the stopping member on the upstream side, once the conveyed object is stopped, lower the stopping member, and convey the conveyed objects one by one to the downstream side. Hereinafter, each embodiment will be described.

[0031] (Embodiment 1) (Stopper unit) In the stopper unit 3 of the present invention, as shown in FIGS. 3 to 6, unit-side rollers 5 and 6 are provided adjacent to the conveying roller 2 and the stopping member 4. The unit-side rollers 5 and 6 are provided with a rotating body 20, which is a power transmission member, between them and the conveying roller 2. The stopper unit 3 has pressing means. Also, as shown in FIG. 1, the stopper unit 3 has a surface plate 30, and the surface plate 30 has a rectangular opening 31, and a part of the unit-side rollers 5 and 6 is exposed from the opening 31. At least the upper surface side of the exposed unit-side rollers 5 and 6 is in contact with the conveyed object, and the unit-side rollers 5 and 6 convey the conveyed object. In FIG. 1, the pressing means to be described later is exposed, but as shown in FIG. 22, the pressing means can be covered with the surface plate 32 so that the pressing means cannot be seen from the surface.

[0032] As shown in Fig. 7, the stop member 4 is provided with a rack 40, and the rack 40 is fixed to the stop member 4. And the stop member 4 is moved up and down through at least two gears. At least one of the gears is a drive gear 41 that rotates by power, and the other one is an intermediate gear 42 that rotates by receiving power directly or indirectly from the drive gear 41. Then, the rotational motion is converted into a linear motion by the rack 40 meshing with the intermediate gear 42, and the stop member 4 moves up and down.

[0033] By providing the intermediate gear 42 smaller than the drive gear 41, even a short stop member 4 can move up and down, and the stopper unit 3 can be made more compact.

[0034] Also, as shown in Fig. 8, the stop member 4 is in contact with four rollers 50. The rollers 50 hold the stop member 4, and when the conveyed object hits the stop member 4, they can absorb the energy due to the impact of the conveyed object on the stop member and relieve the force of collision on the stop member 4.

[0035] (Pressing means) As shown in Figs. 3 to 6, the pressing means includes interlocking plates 24 and 25 connected to the shaft 22 of the rotating body 20, and a biasing member (spring) 26 that biases the interlocking plates 24 and 25. The upper end of the biasing member 26 is attached to the shaft 70, and the lower end is attached to a fixing plate 71 installed at the bottom of the stopper unit. The shaft 70 is welded to the interlocking plate 24 and passes through one end of the interlocking plate 25. The biasing member 26 applies a downward biasing force to the shaft 70. Therefore, by the principle of a lever, an upward biasing force is applied to the shaft 22 connected to the other ends of the interlocking plates 24 and 25. When an upward biasing force is applied to the shaft 22, the rotating body 20 is pushed upward, pressing the conveying roller 2 and the unit-side rollers 5 and 6. Therefore, the unit-side rollers 5 and 6 obtain a transmission force from the conveying roller 2 and rotate in the same direction as the conveying roller 2.

[0036] (Conveying device) As shown in Fig. 9, the conveying device 1 has conveying rollers 2 arranged at equal intervals, and the conveying device 1 has a missing part 35 where the conveying roller 2 is missing. The stopper unit 3 is inserted into the missing part 35 using the conveying roller mounting hole 60 of the frame 13.

[0037] As shown in Figs. 1 and 2, the frame 13 is installed at both ends of the conveying device 1 parallel to the conveying direction of the conveying device 1, and the upper surface of the frame 13 is lower than the upper surface of the conveying roller 2. The stopper unit 3 is connected on the frame 13. Therefore, the outer diameters of the unit-side rollers 5 and 6 and the height of the frame 13 are determined so that no step is generated between the unit-side rollers 5 and 6 and the conveying roller 2.

[0038] Also, as shown in Fig. 21, when the upper surface of the frame 13 is made higher than the upper surface of the conveying roller 2, the stopper unit 3 is connected to the side surface of the frame 13. By doing so, the upper surfaces of the unit-side rollers 5 and 6 of the stopper unit 3 and the upper surface of the conveying roller 2 can be made flush, and no step is generated between the unit-side rollers 5 and 6 and the conveying roller 2.

[0039] The conveying device 1 of the present invention determines in advance a location for grasping the presence of the conveyed object, installs the sensor 9 at that location, and sends a signal for grasping the presence of the conveyed object and raising the stop member 4. As the sensor 9, a known in-stock sensor or line sensor is used. That is, as shown in Fig. 10, the sensor 9 is installed on the frame 13 at a predetermined position on the upstream side E of the stop member 4, detects the conveyed object passing through, and simultaneously sends a signal for raising the stop member 4 to a control device (not shown) of the stopper unit 3.

[0040] (Conveying method) The method for conveying an article using the stopper unit 3 of the present invention is as described below. A sensor 9 is installed on the frame 13 on the upstream side E of the stop member 4. When the sensor 9 detects a conveyed object to be stopped, its signal is transmitted to a control device (not shown) of the stopper unit 3. At this time, the sensor 9 performs positioning in consideration of the rising speed of the stop member and the conveying speed of the conveyed object.

[0041] Next, the rotational force of the conveying roller 2 is transmitted to the unit-side roller 5 via the rotating body 20. The stop member 4 rotates the drive gear 41 with the power from the built-in motor, transmits the rotation to the intermediate gear 42 meshing with the drive gear 41, and further transmits the rotation to the rack 40 meshing with the intermediate gear 42. The rack 40 changes the rotational motion of the intermediate gear 42 into a linear motion to raise the stop member 4 equipped with the rack 40.

[0042] Then, the conveyed object is stopped by the raised stop member 4. At this time, since the roller 50 is in contact with the stop member 4, the force when the conveyed object hits the stop member 4 is dispersed by the roller 50, and the impact on the stop member 4 by the conveyed object is mitigated.

[0043] Since the stop member 4 is rising, the conveyed object stays. Utilizing this staying state of the conveyed object as shown in FIGS. 11 and 12, a label affixing device 62 is installed on the frame 13 on the upstream side E near the stop member 4, and operations such as label affixing can be performed. After the operation is completed, a signal indicating completion is transmitted to a control device (not shown) of the stopper unit 3, and the stop member 4 is lowered. When the stop member 4 is completely lowered, the conveyed object is conveyed to the downstream side F.

[0044] (Manufacturing method) Next, as a manufacturing method of the conveying device 1, as shown in FIG. 9, several conveying rollers 2 are removed from the conveying device 1 in which the conveying rollers 2 are arranged at equal intervals to form a missing portion 35, and the stopper unit 3 is arranged in the missing portion 35.

[0045] That is, as shown in FIG. 9, two conveying rollers 2 are removed to create a missing portion 35. Also, when fixing the stopper unit 3, the conveying roller mounting hole 60 after removing the conveying roller 2 is utilized. Then, the stopper unit 3 shown in FIG. 3 is arranged and fixed to the conveying roller mounting hole 60 by fixing means such as screws. Therefore, the labor of reworking the mounting hole for attaching the stopper unit 3 to the frame 13 can be saved, and the manufacturing cost can be suppressed.

[0046] Furthermore, by using the stopper unit 3, the conveyed object can be temporarily stopped and detained, and the operator can work at his own pace even if the line speed is high.

[0047] (Second Embodiment) As another embodiment of the present invention, the rotating member is a conveying rotating member that contacts the conveyed object and moves the conveyed object, and a plurality of conveying rotating members are arranged in parallel. (Stopper Unit) As shown in FIG. 13, the stopper unit 103 is provided with a stop member 104 adjacent to the conveying rotating member 102. As shown in FIG. 14, a rack 140 is provided on the stop member 104, and the rack 140 is fixed to the stop member 104. And a drive gear 141 that meshes with the rack 140 and rotates by power is provided. That is, the drive gear 141 that rotates by obtaining power from the built-in motor is meshed with the rack 140, the rotational motion of the drive gear 141 is converted into a linear motion of the rack 140, and the stop member 104 is lifted and lowered.

[0048] At this time, protrusions 180 are provided on both the upstream side E and the downstream side F of the stop member, and a proximity sensor 181 is installed in the stopper unit 103 to detect the presence or absence of the protrusions 180. One of the proximity sensors detects the case where the protrusion 180 exists, and when the presence of the protrusion is detected, a signal is sent to stop the lifting of the stop member 104. In the other proximity sensor, when the sensor detects the conveyed object, the stop member 104 rises, but when it reaches the upper limit, the presence of the protrusion 180 cannot be detected. Also, when the protrusion 180 cannot be detected, a signal is sent to stop the lifting of the stop member 104, and it can also be sent to a control device (not shown) of the stopper unit 103.

[0049] (Rotating member for conveyance) As shown in Fig. 18, the appearance of the rotating member 102 for conveyance has a shape in which a large-diameter portion 121 and a small-diameter portion 122 are alternately provided on the central axis. The large-diameter portion 121 has a hollow structure. Since the rotating member 102 for conveyance has a cavity inside, when the conveyed object collides, the large-diameter portion 121 is easily deformed, reducing the impact of the collision. Therefore, even when the conveyed object collides, it is difficult for noise to occur, and it is also difficult to damage the conveyance part. As shown in Fig. 17, in the conveying device 101, both ends of the rotating member 102 for conveyance are rotatably supported by the opposing frames 113. As shown in Fig. 18, in the conveying device 101, the rotating members 102 for conveyance are densely arranged, and in the adjacent rotating members 102 for conveyance, the large-diameter portion 121 of one rotating member 102 for conveyance enters the position of the small-diameter portion 122 of the other rotating member 102 for conveyance. That is, in the conveying device 101, as shown in Fig. 18, the axial distance L between the adjacent rotating members 102 for conveyance is short. Assuming the diameter of the large-diameter portion 121 is D, the axial distance L is smaller than the diameter D of the large-diameter portion 121. Assuming the diameter of the small-diameter portion 122 is d, (D + d) / 2 is slightly smaller than the axial distance L. That is, (D + d) / 2 is 70 percent or more of the axial distance L, and more preferably 80 percent or more.

[0050] Therefore, the gap Sa between the small-diameter portion 122 and the large-diameter portion 121 of the adjacent conveying rotating member 102 is extremely small, and the gap Sa is 15% or less of the diameter D of the large-diameter portion 121, more preferably 10% or less.

[0051] Also, when the length of the large-diameter portion 121 is A and the length of the small-diameter portion 122 is B, the length A of the large-diameter portion 121 is slightly smaller than the length B of the small-diameter portion 122. That is, the length A of the large-diameter portion 121 is 70% or more of the length of the small-diameter portion 122, more desirably 80% or more. Therefore, the axial gap Sb between the large-diameter portions 121 of the adjacent conveying rotating members 102 is extremely small. Therefore, the conveying device 101 has few gaps as a whole and is in a dense state.

[0052] Although not limited, the diameter D of the large-diameter portion 121 is about 25 mm to 80 mm, preferably about 30 mm to 60 mm. The gap Sa between the small-diameter portion 122 and the large-diameter portion 121 of the adjacent conveying rotating member 102 is 10 mm or less, preferably 3 mm or less.

[0053] (Conveying device) In the conveying device 101 of the present embodiment, the conveying rotating members 102 are densely arranged, the conveying object has many opportunities to contact the conveying rotating members 102, and the conveying object is not likely to rattle. Further, since the gaps of the conveying device 101 of the present embodiment are small, even when conveying a small-sized conveying object, it is difficult for the conveying object to fall between the conveying rotating members 102. In addition, since the valleys between the adjacent conveying rotating members 102 of the conveying device 101 of the present embodiment are discontinuous in the width direction of the conveying device 101, even when conveying a small-sized conveying object, it is difficult for the conveying object to fall between the conveying rotating members 102. That is, in the conventional conveying device, as shown in FIG. 19(b), the valleys 131 of the conveying rotating member 102 are continuous in the width direction of the conveying device. Therefore, in the conventional conveying device, it is easy for the conveyed object to fall between the conveying rotating members 102. Even if the conveyed object is long in the width direction of the conveying device, if the length of the conveyed object in the running direction of the conveying device is short, it will get stuck in the valleys 131 of the conveying rotating member 102 and cannot get out.

[0054] Since the belt conveyor does not have a conveying rotating member, it can also convey small-sized conveyed objects. However, the belt conveyors used in factories and shipping yards are formed by connecting short belt conveyors in series, and gaps are formed between the short belt conveyors. When a conveyed object with a small outer shape is conveyed by a belt conveyor, the conveyed object will get stuck in the joint part of the short belt conveyors and cannot get out.

[0055] On the other hand, in the conveying device 101 of the present embodiment, the valleys 133 of the adjacent conveying rotating members 102 are arranged in a staggered manner, and the valleys 133 of the adjacent conveying rotating members 102 are discontinuous in the width direction of the conveying device 101. Therefore, in the conveying device 101 of the present embodiment, even if the conveyed object is short in the width direction of the conveying device 101, it will be supported by a plurality of large-diameter portions 121. When the conveyed object is long in the width direction, it will naturally be supported by a plurality of large-diameter portions 121 and will not fall into the valleys. Therefore, according to the conveying device 101 of the present embodiment, even if a conveyed object with a small outer shape is conveyed, it can be conveyed smoothly.

[0056] Focusing on the end of the conveying device 101, as shown in FIG. 20, the conveying rotating member 102 is pivotally supported at the end of the frame 113, and a part of the large-diameter portion 121 protrudes outside the frame 113. Therefore, when the conveying rotating members 102 are connected in series, the large-diameter portion 121 of the conveying rotating member 102 arranged at the end of the other conveying device 101 enters the position of the small-diameter portion 122 of the conveying rotating member 102 arranged at the end of one conveying device 101. Therefore, according to the conveying device 101 of the present embodiment, the gap is small even at the joint of the conveying device 101, and the conveyed object does not fall into the valley.

[0057] (Manufacturing method) Next, as a manufacturing method of the conveying device 101, as shown in FIG. 15, several of the conveying rotating members 102 are removed to form a missing portion 135, and the stopper unit 103 is arranged in the missing portion 135.

[0058] That is, as shown in FIG. 15, 3 to 4 of the conveying rotating members 102 are removed to create a missing portion 135. Then, the square member 190 is fixed to the frame 113 with bolts or the like. Then, as shown in FIG. 16, a coupler is used. The L-shaped member 191, which is one of the couplers fixing the shaft of the roller 150, is overlapped on the upper part of the square member 190, which is the other coupler, and fixed with bolts or the like. After installing the stopper unit 103, the conveying rotating member 102 is restored to the space other than the stopping member 104 appearing on the surface, and the conveying device 101 is completed. At this time, the completed stopper unit 103 finally only needs to remove at least one of the conveying rotating members 102.

[0059] In the present embodiment, one stopper unit is used in the conveying device. However, during operations such as attaching labels using the stopper unit, other stopper units are provided on the more upstream side so that other conveyed objects do not get mixed in, and during the label attaching operation, the subsequent conveyed objects can also be temporarily stopped.

[0060] In the present embodiment, a plate is used as the stopping member, but it is not limited to this, and for example, a column such as a square column may also be used.

[0061] Furthermore, in the first embodiment, an intermediate gear is provided as a means for moving the stopping member up and down, but this may not be provided.
