Fig. 1 is a perspective view of a carrier 200 having a blocking mechanism 100. Fig. 2 is a perspective view of the blocking mechanism 100. Fig. 3 is an enlarged view at a in fig. 2. Fig. 4 is a schematic view of the docking of a carrier 200 with a blocking mechanism 100 and a docking apparatus 300. Fig. 5 is an enlarged view at B in fig. 4. Referring to fig. 1 to 3 with additional reference to fig. 4, the stopper mechanism 100 according to the first embodiment is provided on a transport carrier 200 and is configured to stop an object 201 to be transported placed on the transport carrier 200. The blocking mechanism 100 includes: a first mounting part 101, a blocking part 102, an elastic part 103 and a driving part 104. The first mounting member 101 is provided with a guide portion 105 that is guided along a straight line. The stopper 102 moves in the guiding direction of the guide portion 105 to switch between a stopping position where the object 201 is restricted from being conveyed and a releasing position where the object 201 can be conveyed. The elastic member 103 is provided on one side of the blocking member 102 in the guide direction. One end of the elastic member 103 is fixed, and the other end is connected to the stopper 102, so that the stopper 102 is urged to move to the stopper position. The drive member 104 is connected to the blocking member 102 and is disposed on the other side of the blocking member 102 with respect to the elastic member 103 in the guide direction so as to be driven in such a manner as to move the blocking member 102 toward the release position.

According to the stopper mechanism 100 of the present embodiment, it is possible to be provided in the transport vehicle 200 without independent power, to stop the object 201 placed on the transport vehicle 200, or to be driven to switch to the release position so that the object 201 can be transported. Specifically, by providing the elastic member 103 and biasing the stopper 102 so that the stopper 102 moves to the stopping position (upward in the drawing) by the elastic member 103, even when the transport vehicle 200 does not have independent power, the stopper 102 can be held at the stopping position, and the object 201 to be transported can be reliably stopped. Further, since the driving member 104 is provided, the driving member 104 is connected to the stopper 102 and is driven in such a manner as to move the stopper 102 toward the release position (downward in the drawing). Therefore, when the transport carrier 200 and the docking facility 300 are docked, the drive unit 301 (for example, a drive device such as an air cylinder 302) provided in the docking facility 300 can drive the drive unit 104 and further switch the stopper 102 to the release position, thereby enabling the object 201 to be transported on the transport carrier 200.

The application of the carrier 200 is not particularly limited, and examples thereof include: production workshops, warehouses, logistics workshops, marine storage rooms, restaurants, stereo garages and the like. The mode of carrying the carrier 200 is also not particularly limited, and examples thereof include: AGV car transport, robot transport, etc. The object 201 is not particularly limited, and examples thereof include: the tray is used for bearing materials, the clamp is used for clamping the materials, the jig is used for positioning the materials, and various materials, various goods and the like are arranged on the tray. For convenience of description, the following description will be given taking as an example a case where the transport vehicle 200 is transported by an AGV (not shown) installed in an automation plant, the transport vehicle 200 is docked with the docking facility 300, and materials are transported between the transport vehicle 200 and the docking facility 300.

Referring to fig. 1, the carrier 200 according to the present embodiment includes, for example, a conveyor 202, the conveyor 202 being used to carry an object 201, and the stopper mechanism 100 described above being provided at the front end and/or the rear end of the conveyor 202. Specifically, the conveyor belt 202 may be, for example, a belt, a timing belt, a chain, or the like, and the conveyor belt 202 is not provided with independent power. Correspondingly, the docking facility 300 is provided with a docking mechanism (not shown) for docking with the transport carrier 200. The docking mechanism may be a known docking mechanism such as a gear docking mechanism or a claw docking mechanism. In the case where the transport carrier 200 and the docking apparatus 300 are docked, the docking mechanism of the docking apparatus 300 connects a transmission such as a motor or the like provided on the docking apparatus 300 and the conveyor belt 202 on the transport carrier 200, and drives the conveyor belt 202 to operate. This enables the transfer of materials between the transfer carrier 200 and the docking facility 300. The blocking mechanism 100 is provided at the front end and/or the rear end of the conveyor belt 202, and thus, when the AGV vehicle carries the transport carrier 200, the material on the conveyor belt 202 can be blocked and prevented from falling. The docking facility 300 is provided with a driving unit 301 having a driving element such as an air cylinder 302, for example, and when the transport carrier 200 and the docking facility 300 are docked, the air cylinder 302 drives the driving unit 104 of the blocking mechanism 100 to switch the stopper 102 from the blocking position to the release position, thereby enabling the material (i.e., the object 201) to be transported between the transport carrier 200 and the docking facility 300. Therefore, even when it does not have independent power, it is possible to stop the object 201 on the transport carrier 200, or to cause the stop mechanism 100 to be driven and switched so that the object 201 can be transported.

The carrier 200 of the present embodiment is provided with, for example, two left and right conveyors 202.

With continued reference to fig. 2 and 3, in some embodiments, in order to simplify the structure of the guide portion 105, the first mounting element 101 is provided with a first groove 106 serving as the guide portion 105. Specifically, for example, a commercially available aluminum profile may be used as the first mounting piece 101, and mounting grooves (left and right sides in the drawing) of the aluminum profile may be used as the first groove portions 106. An aluminum profile as the first mounting member 101 is attached to the carrier 200 so as to extend in the vertical direction. The first mounting member 101 is mounted in the middle of the carrier 200 in the left-right direction and extends in the up-down direction of the carrier 200.

In addition, in order to easily mount the blocking member 102 and to allow the blocking member 102 to easily move relative to the first mounting member 101, in some embodiments, the blocking mechanism 100 further includes a second mounting member 107, the blocking member 102 is mounted to the second mounting member 107, a sliding member 108 is disposed on the second mounting member 107, and the sliding member 108 slides along the first groove portion 106. Specifically, the second mounting member 107 may be an aluminum profile, and the second mounting member 107 extends in the left-right direction. A plurality of stoppers 102 (e.g., 2) are mounted on the second mounting member 107. One of the stops 102 is located to the left of the second mounting member 107 for stopping or releasing material on the left side conveyor belt 202 of the carrier 200. Another stop 102 is located to the right of the second mounting member 107 for stopping or releasing material on the conveyor belt 202 on the right side of the carrier 200. The slider 108 includes, for example, two sliders, and is provided at an interval in the left-right direction of the second mounting member 107. Each slider 108 is provided with a slider 109 having a cross section adapted to the cross section of the first groove 106. For example, when the cross-sectional shape of the first groove portion 106 is substantially T-shaped, the cross-sectional shape of the sliding portion 109 is also substantially T-shaped. One of the slide members 108 slides along the first groove portion 106 on the left side of the aluminum profile member as the first mounting member 101 by its slide portion 109. The other slide member 108 slides along the first groove portion 106 on the right side of the aluminum profile member as the first mounting member 101 by its slide portion 109. Thus, by providing the second attachment 107 and the slider 108, the stopper 102 can be easily attached to the left-right direction, and the stopper 102 can be easily moved relative to the first attachment 101.

In some embodiments, to easily mount the elastic member 103, the other end of the elastic member 103 is connected to the second mounting member 107. Specifically, in the case where the second mounting member 107 is provided, one end of the elastic member 103 is fixed to, for example, an upper end portion of the first mounting member 101, and the other end of the elastic member 103 is connected to the second mounting member 107. The elastic member 103 may be a spring member selected from a tension spring, a compression spring, and the like. Taking a tension spring as an example, one end of the tension spring is attached to a first spring support 110 provided at an upper portion of the first mounting member 101, and the other end of the tension spring is connected to a second spring support 111 provided at a middle portion in the left-right direction of the second mounting member 107. In addition, the first mounting member 101 is further provided with an upper limiting member 112, and the upper limiting member 112 can be selected from, for example, a bolt member, can be adjusted in the up-down direction, and limits the position of the second mounting member 107 in the up-down direction. In the absence of an external force, the tension spring as the elastic member 103 pulls the second mounting member 107 in the upward direction, and the second mounting member 107 is restricted by the upper restricting member 112. Thus, in the absence of external force, the stopper 102 attached to the second attachment member 107 is stably held in the stopping position upward by the upward pulling of the tension spring and the stopping of the upper stopper 112.

With continued reference to fig. 3, and with additional reference to fig. 2, in some embodiments, to easily actuate the blocking member 102 to switch the blocking member 102 from the blocking position to the release position, the blocking mechanism 100 further includes a transition portion 113, the transition portion 113 including: a connector 114, a third mount 115, and a support shaft 116. Wherein the connecting member 114 is connected to the second mounting member 107. The third mounting member 115 is fixed to the first mounting member 101, and the third mounting member 115 is provided with a second groove portion 117, and the extending direction of the second groove portion 117 intersects with the guiding direction (up-down direction in the drawing) of the guide portion 105. The support shaft 116 is held by the second groove portion 117 and slides within the second groove portion 117. One end (hereinafter referred to as "first end 104 a" for convenience of description) of the driving member 104 is hinged to the link 114, the middle portion of the driving member 104 is hinged to the support shaft 116, and the other end (hereinafter referred to as "second end 104 b" for convenience of description) of the driving member 104 is driven in the guide direction. Specifically, the connecting member 114 may also be selected from, for example, an aluminum profile member, and the connecting member 114 is connected to the middle portion in the length direction of the second mounting member 107. The third mounting member 115 is plate-shaped and includes two pieces, and is fixed to the left first groove 106 and the right first groove 106 of the first mounting member 101 by screws. The second groove 117 provided in the third attachment member 115 is a long groove, and the second groove 117 extends in the front-rear direction (i.e., the extending direction of the second groove 117 is orthogonal to the guiding direction). The driving members 104 are plate-shaped and comprise two pieces, wherein the first end 104a of one driving member 104 is hinged to the left side of the connecting member 114 and the first end 104a of the other driving member 104 is hinged to the right side of the connecting member 114. The middle portion of the two-piece driving member 104 in the longitudinal direction is hinged to both ends of the support shaft 116 in the axial direction, and is bridged to the second groove 117 of the third mounting member 115 by the support shaft 116.

With continued reference to fig. 4 and 5, when the air cylinder 302 of the driving portion 301 of the docking apparatus 300 pushes the second end portion 104b of the driving member 104 upward from below the second end portion 104b of the driving member 104, the driving member 104 swings around the supporting shaft 116, and at the same time, the driving member 104 slides along the second groove portion 117 through the supporting shaft 116, the first end portion 104a of the driving member 104 swings downward, and the connecting member 114 hinged to the first end portion 104a of the driving member 104 is pulled to move downward. Since one end of the connecting member 114 is fixed to the second mounting member 107 and the stopper 102 is also mounted to the second mounting member 107, the stopper 102 moves downward along with the second mounting member 107 when the first end portion 104a of the driving member 104 swings downward. Thereby, the blocking member 102 is switched from the blocking position to the release position.

With continuing reference to figure 3 and with additional reference to figure 5, in some embodiments, the other end of the drive member 104 is bracketed by a roller 118. Specifically, the rolling member 118 may be, for example, a roller, and the rolling member 118 is mounted on the second ends 104b of the two driving members 104. A pick 303 is connected to the air cylinder 302 of the driving part 301 of the docking apparatus 300, and when the air cylinder 302 of the driving part 301 of the docking apparatus 300 drives the driving member 104 from below the second end 104b of the driving member 104, the pick 303 abuts against the roller 118 and pushes the roller 118 and the driving member 104 to swing. By providing the rolling member 118, the friction force when the paddle 303 pushes the driving member 104 can be reduced.

With reference to fig. 1 and 2, the transport vehicle 200 may include, for example, two or more layers in the vertical direction, and two left and right conveyor belts 202, for example, may be provided for each layer. Correspondingly, the second mounting members 107 may include a plurality of second mounting members 107 arranged at intervals in the guiding direction, the stoppers 102 are respectively mounted on the second mounting members 107, and the second mounting members 107 are respectively connected to the connecting members 114. Specifically, for example, the second mounting member 107 includes two members, one of which is connected to the upper end of the connecting member 114 in the longitudinal direction and the other of which is connected to the lower end of the connecting member 114 in the longitudinal direction. The third mounting part 115 is mounted to a middle portion of the first mounting part 101 in a lengthwise direction, and the driving parts 104, etc. are connected to middle portions of the connecting parts 114 in a lengthwise direction, respectively. Thereby, the air cylinder 302 of the driving part 301 of the docking apparatus 300 can drive the driving piece 104 at the middle portion in the up-down direction of the stopper mechanism 100 and switch the stoppers 102 mounted on the two second mounting pieces 107 in the up-down direction between the stopper position and the release position.

Thus, in the case where the carrier 200 has two upper and lower stages, and two left and right conveyors 202 are provided for each stage, for example, the stopper mechanism 100 is provided with two second mounting devices 107 in the vertical direction, and the stoppers 102 are attached to the second mounting devices 107 in the left and right directions, respectively. The two second mounting parts 107 in the up-down direction are connected by the connecting part 114, and the elastic part 103 is disposed above the second mounting part 107 in the upper part, and then the driving part 104 and the middle part in the up-down direction of the connecting part 114 are connected. Thus, when the driving member 104 is driven by the air cylinder 302 of the driving portion 301 of the docking apparatus 300, the four stoppers 102 can be simultaneously switched from the stopper position to the release position, so that the driving portion 301 of the docking apparatus 300 can be greatly reduced, and the cost of the docking apparatus 300 can be reduced.

In addition, although the description has been given above taking an aluminum profile as the first mounting member 101 as an example, the present invention is not limited thereto. For example, a square tube, a channel, a long steel plate, or the like may be used as the first mounting device 101.

Although the above description has been given by taking the stopper 102 as an example of switching the position in the vertical direction, the present invention is not limited to this. For example, the stopper 102 may be switched between the left-right direction position and the other direction position as long as it can block the material as the object 201 and release the material. In the case where the stopper 102 needs to be switched in position in the left-right direction, the guide 105 provided in the first fixture 101 needs to be extended in the left-right direction.

In addition, although the first groove 106 is opened in the first fixture 101 as an example, the present invention is not limited to this. In some embodiments, the guide part 105 may include a linear slide rail (not shown) or a linear guide shaft (not shown) mounted to the first mounting part 101, and the driving part 104 slides linearly along the linear slide rail or the linear guide shaft by a slider (not shown).

Although the example in which the stopper 102 is attached to the second attachment member 107 and the slider 108 is provided on the second attachment member 107 has been described above, the present invention is not limited to this. In some embodiments, the blocking member 102 may also be provided with a sliding portion 109, and the sliding portion 109 slides along the first groove portion 106. Specifically, for example, the sliding portion 109 of the stopper 102 may be provided with reference to the sliding portion 109 of the slider 108, and will not be described further herein.

Although the above description has been given by taking an example in which the transfer unit 113 is connected to the second attachment member 107 by the connector 114, the present invention is not limited to this. In some embodiments, for example, where the transport carrier 200 has only one tier, or each obstacle 102 is driven by a separate drive 104, the transfer section 113 may include: the third mounting member 115 and the support shaft 116, but not the connecting member 114. Wherein the third mounting element 115 is fixed to the first mounting element 101 and arranged beside the barrier 102. Similarly, the third mounting element 115 is also provided with a second groove 117, and the extending direction of the second groove 117 intersects with the guiding direction. The support shaft 116 is held by the second groove portion 117 and slides within the second groove portion 117. The first end 104a of the driving member 104 is hinged to the blocking member 102, the middle portion of the driving member 104 is hinged to the support shaft 116, and the second end 104b of the driving member 104 is driven in the guiding direction. Thus, in this embodiment, the driving member 104 can be directly connected to the blocking member 102 without being connected to the blocking member 102 via the second mounting member 107 and/or the connecting member 114.

Although the above description has been made by taking an example in which the stopper mechanism 100 is provided at the front end and/or the rear end of the conveyor belt 202 of the carrier 200, the present invention is not limited to this. For example, the transport carrier 200 may include only a stage (not shown) for placing the object 201 without including a conveyor, and the stopper mechanism 100 of each of the above embodiments may be similarly provided on the transport carrier 200. When the transport carrier 200 is transported by an AGV or an operator, the stoppers 102 of the stopper mechanism 100 are in the stopping position, whereby the materials on the transport carrier 200 can be prevented from falling. When the carrier 200 needs to be docked with the docking apparatus 300, the stopper 102 is switched to the release position by the air cylinder 302 of the driving unit 301 of the docking apparatus 300, and then the material or the like is transferred between the docking apparatus 300 and the carrier 200 by a robot or an operator or the like. In the present embodiment, since the above-described stopper mechanism 100 is provided, even when it does not have independent power, it is possible to stop the object 201 on the transport carrier 200, or to cause the stopper mechanism 100 to be driven and switched so that the object 201 can be transported.
