Description

Technical Field

[0001] The utility model belongs to the technical field of hanging equipment, and relates to a lifting arm device for preventing backward movement out of a station and a hanging equipment. Background Art

[0002] The lifting arm device is installed in the workstation of the hanging assembly line, and its main functions are as follows: when installed at the first station, it transports the carrier (such as a hanger) from a low position to a high automatic transport line; when installed at the workstation, it transports the fabric completed by the operator in the current process to the high automatic transport line through the carrier, and then sends it to the next workstation to complete a new process.

[0003] The lifting arm device in the prior art generally rotates a belt or chain driven by a motor, and a push block is installed on the belt or chain. The push block drives the carrier from a low position to a high position, and the push block is positioned by a Hall sensor or a reed switch installed at the lower end of the lifting arm.

[0004] The following problems are common during the operation of the lifting arm device: after the carrier is transported from a low position to a high position, when leaving the station, the swing of the carrier body drives the rollers of the carrier to retreat, causing the carrier to fall to the bottom of the lifting arm.

[0005] Regarding the working principle of the lifting arm device, reference may be made to the anti-retraction mechanism for hanging in a garment assembly line provided in Application No. 201821277584.7. The anti-retraction mechanism can prevent the carrier from retracting when entering a station, but cannot prevent the carrier from retracting when leaving a station. Summary of the invention

[0006] The utility model aims at the above problems existing in the prior art and provides a lifting arm device for preventing a vehicle from rolling back when leaving a station. The technical problem to be solved by the utility model is: how to prevent a vehicle from rolling back when leaving a station.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] A lifting arm device for preventing rollback at exit, the lifting arm device comprises a track, the track comprises an entry section, a lifting section and an exit section connected in sequence, and is characterized in that a block is arranged on the exit section, and the block extends from above the exit section.

[0009] The rollers of the carrier roll on the track, allowing the carrier to enter the station from the entry section, and then driven by the push block to make the carrier pass through the lifting section. After that, the rollers of the carrier pass over the block and enter the exit section. The push block is separated from the carrier and the carrier exits the station.

[0010] After the rollers of the carrier enter the exit section, when the carrier body swings and drives the rollers of the carrier to retreat, the block extending from the top of the exit section can block the rollers to prevent the carrier from falling back to the bottom of the lifting section during exiting, thus avoiding the problem of double carriers.

[0011] In the above-mentioned lifting arm device for preventing backward movement at the exit, the lifting section extends vertically, the exit section extends horizontally, and the stopper is arranged at the connection between the lifting section and the exit section.

[0012] The stopper is arranged at the connection between the lifting section and the exit section. This structure enables the rollers of the vehicle to pass over the stopper as soon as they pass the lifting section, so that the vehicle can enter the exit section more quickly.

[0013] The block is located at the end of the exit section. No matter where the vehicle is located in the exit section, the block can block the rollers of the vehicle to better prevent the vehicle from rolling back when leaving the station.

[0014] In the above-mentioned lifting arm device for preventing back-off at the exit, a side of the stopper away from the lifting section has an inclined surface, and the inclined surface gradually slopes downward from the inside to the outside.

[0015] From inside to outside refers to the direction from close to the lifting section to far away from the lifting section. The inclined surface of the block plays a buffering role. When the roller of the vehicle retreats, the roller contacts the inclined surface, the roller is in an uphill state and gradually slows down to a stop. This structure not only blocks and buffers the vehicle, but also prevents the vehicle from violently hitting the block when retreating.

[0016] In the above-mentioned lifting arm device for preventing retreat at exit, the side of the stopper close to the lifting section has an arc-shaped surface, and the arc-shaped surface is adapted to the shape of the outer side surface of the lifting section and the two are flush.

[0017] The arc surface of the stopper is adapted to the shape of the outer side surface of the lifting section and the two are flush. This structure makes it easier for the rollers of the carrier to enter the station entrance section from the lifting section and exit the station more smoothly.

[0018] The utility model also provides a hanging device, which comprises any one of the above-mentioned lifting arm devices.

[0019] Compared with the prior art, the advantages of the utility model are as follows:

[0020] In the lifting arm device, the block extending from the top of the exit section can block the rollers of the carrier to prevent the carrier from falling back to the bottom of the lifting section when exiting the station, thereby avoiding the problem of double carriers (hangers).
