Description

Technical Field

[0001] The utility model relates to an assembly line, in particular to a limiting device for limiting the position of a carrier on the assembly line. Background Art

[0002] Assembly lines are used to transport items, such as fabric cuts and garments in garment systems, and merchandise in supermarket online conveyor systems. To transport items, assembly lines rely on carriers, which are loaded onto the carriers and driven by flexible drive mechanisms along the assembly line's tracks. Due to space constraints, assembly lines are generally not designed to be purely linear. Curved paths or branch paths are often required to compensate for the space constraints on the carrier's path. Consequently, the carrier's path sometimes requires turns or track changes to accommodate changes in path. Changes in the carrier's path inevitably result in significant swings, which can lead to relatively poor stability. For some empty carriers, since they are unloaded, the force exerted by their attachments on the tracks is minimal, making them less able to withstand changes in path. This can lead to excessive roll angles and resulting falls. Consequently, existing assembly lines suffer from poor operational stability, especially for empty carriers during path changes. Utility Model Content

[0003] The technical problem to be solved by the present invention is: to provide an assembly line hanging type carrier limiting device, which can provide good protection for the carrier when it is moving on the track, especially when the path changes, so that the vehicle has good travel stability on the track.

[0004] In order to solve the technical problems, the technical solution of the utility model is: a pipeline-mounted carrier limiting device, comprising a mounting frame and a track, a channel for the carrier to pass through is formed between the mounting frame and the track, and is characterized in that a plurality of connecting structures are provided on the mounting frame, and limiting members are provided on the connecting structures, and two adjacent limiting members are staggered in the horizontal and / or vertical directions, and the limiting members have a contact surface or contact line for contacting the carrier, and the contact surface or contact line is facing the channel.

[0005] This limit device is typically installed at track changes or turns. This can be achieved by identifying common problem locations through practical application, or through theoretical and practical experience. The term "channel" refers to the spatial path of the vehicle as it travels along the track. This limit device is used to limit the corresponding position of the vehicle to prevent it from swinging too far and falling.

[0006] Furthermore, the mounting frame includes a connecting frame, the upper end of which is connected to the track, the connecting frame having a protrusion protruding toward one side of the track, and the lower end of the connecting frame having the connecting structure. The stopper on the connecting structure is used to limit the shoulder of the carrier, and the connecting frame facilitates the installation of the connecting structure, resulting in a simple structure and convenient installation.

[0007] Furthermore, an upper frame is connected to the protrusion, and the upper frame is in a U-shaped shape. The track passes through the upper frame, with one end of the upper frame connected to the protrusion and the other end of the upper frame extending into the other side of the track. The arrangement of the upper frame provides options for the location of the connection structure, facilitating the fixing and arrangement of multiple limiters.

[0008] Furthermore, the connecting structure is located in the middle of the top of the upper frame, close to the upper surface of the track, and is located at the other end of the upper frame. A stopper on the connecting structure close to the track is used to limit the carrier's attachment portion, thereby confining the carrier to the track and ensuring the carrier's positional stability on the track.

[0009] Furthermore, the orthographic projections of the connecting structure at the top of the upper frame and the connecting structure at the lower end of the connecting frame overlap. This arrangement is reasonable and facilitates providing a stable limiting effect on the carrier.

[0010] Furthermore, the upper frame and the connecting frame are formed by bending sheets of equal width, thereby facilitating the preparation of the mounting frame, and the shape of the mounting frame can well meet actual work needs.

[0011] Furthermore, the connection structure is a connector having an F-shaped cross-section and a mounting opening formed on the connector, and the limiter is fixedly connected within the mounting opening. The connector is generally made of aluminum profile, has a simple structure, and can provide a stable connection for the limiter.

[0012] Furthermore, protruding ridges are integrally formed on opposite side surfaces of the limiting member, and the ridges are used to abut against the mouth of the installation opening, so that the installation position of the limiting member in the installation opening is stable.

[0013] Compared with the prior art, the present invention has the following advantages: by providing a mounting bracket on the periphery of the track to provide a mounting location for the connecting structure and the limiting member, a limiting effect is formed around the track. Combined with the requirements for the relative positions of the connecting structures, the vehicle is limited in all directions when moving forward on the track, and the vehicle has good stability when moving on the track. Even when an empty vehicle moves forward on the track, it can be relatively stably maintained on the track under the restraining effect of the limiting member, facilitating the transportation of the empty vehicle.

[0019] In conjunction with the drawings in the specification, this assembly line hanging type vehicle limiting device is used to limit the hanging type vehicle 2 when it is traveling on the track 1, so that the vehicle 2 has good travel stability on the track 1 and is not prone to falling. This limiting device is mainly set at a position on the track 1 where the vehicle 2 is prone to swinging too much, such as the track change position or the turning position of the track 1. The vehicle 2 shown in the figure includes a hook 21 and a body 23, and a pull rod 22 is provided between the hook 21 and the body 23 to connect the two.

[0020] The structure of the present limiting device includes a mounting frame 3 and a track 1. A channel for the vehicle 2 to pass through is formed between the mounting frame 3 and the track 1, and the trajectory of the vehicle 2 traveling on the track 1 constitutes the channel. A number of connecting structures are provided on the mounting frame 3, and a limiting member 4 is provided on the connecting structure. Two adjacent limiting members 4 are staggered in the horizontal and / or vertical directions, so that a plurality of limiting points can be formed to limit the vehicle 2, and these limiting points are staggered. The limiting member 4 has a contact surface or contact line for contacting the vehicle 2, and the contact surface or contact line faces the channel. Under normal circumstances, the end face of the limiting member 4 facing the channel is a convex arc surface, and the convex arc surface is in line contact with the vehicle 2 to achieve limiting.

[0021] The mounting bracket 3 includes a connecting bracket 31. The upper end of the connecting bracket 31 is connected to the track 1. Specifically, the connecting bracket 31 is connected to the lower surface of the track 1 and is connected to the necking groove on the back side of the track 1 through bolts, and the upper end of the connecting bracket 31 is fixedly fitted to the lower surface of the track 1. The connecting bracket 31 has a protruding portion protruding toward the track 1. The lower end of the connecting bracket 31 is provided with the connecting structure described above. The limiting member 4 on the connecting structure is used to limit the main body 23 of the carrier 2 from above. An upper bracket 32 is connected to the protruding portion. The upper bracket 32 is in a "冂" shape, and the track 1 passes through the upper bracket 32. One end of the upper bracket 32 is connected to the protruding portion, and the other end of the upper bracket 32 extends to the other side of the track 1. The upper bracket 32 and the connecting bracket 31 are formed by bending sheet bodies of the same width, generally made of aluminum profiles. The connecting structure described above is provided at the middle position of the top of the upper bracket 32. This connecting structure is located directly above the track 1. The limiting member 4 on this connecting structure is close to the upper surface of the track 1 and is used to limit the hook 21 on the carrier 2, so that the hook 21 is stable on the track 1. The positive projections of the connecting structure at the top of the upper bracket 32 and the connecting structure at the lower end of the connecting bracket 31 overlap, and their connection is in the vertical direction. The connecting structure described above is provided at the other end of the upper bracket 32. The limiting member 4 on this connecting structure is used to limit the pull rod 22 on the carrier 2, so as to prevent the carrier 2 from swinging too much in the direction of the other end of the upper bracket 32 on the track 1.

[0022] The connecting structure is a connecting member 5. The connecting member 5 is made of aluminum profile. The cross-section of the connecting member 5 is in an "F" shape, so that a mounting opening 51 is formed at one end of the connecting member 5. The other end of the connecting member 5 is fixedly fitted to the corresponding part on the mounting bracket 3, and the limiting member 4 is fixedly connected in the mounting opening 51. The limiting member 4 is generally a plastic part.
