Description

Technical Field

[0001] The utility model belongs to the technical field of hanging equipment and relates to a lifting arm device of the hanging equipment and the hanging equipment. Background Art

[0002] The lifting arm device is installed in the workstation of the hanging assembly line. 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-level automatic transport line; when installed at a workstation, it transports the fabric completed by the operator in the current process to the high-level automatic transport line through the carrier and 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. A push block is installed on the belt or chain. The push block drives the carrier from a low position to a high position. The push block is positioned by a Hall sensor or 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 enters the bottom of the lifting arm, when the carrier is overloaded, the carrier will swing greatly with the weight, driving the carrier's rollers to retreat. At this time, the push block may not push the carrier's rollers and the carrier will be empty. The carrier will continue to stay at the bottom of the lifting arm device, resulting in a double carrier, or the push block may just hit the carrier's rollers, causing the motor to stall.

[0005] Application No. 201821277584.7 provides an anti-backward mechanism for hanging in a garment assembly line, which includes a base and a swing tongue. The lifting device includes a lifting track and a lifting mechanism. The base is fixed to the bottom of the lifting track, the swing tongue is pivotally connected to the base, and an elastic reset mechanism is provided between the swing tongue and the base. The swing tongue can swing left and right relative to the base; a blocking part is provided on one side of the swing tongue, and the initial state of the blocking part is at the lifting channel of the lifting device.

[0006] The aforementioned anti-retraction mechanism can prevent the vehicle from retracting. However, designing an anti-retraction lifting arm device with a different structure is an inevitable requirement for technological innovation. Summary of the Invention

[0007] In view of the above problems existing in the prior art, the present invention provides a lifting arm device for a hanging device. The technical problem to be solved by the present invention is: how to prevent the carrier from falling back.

[0008] The purpose of this utility model can be achieved through the following technical solutions:

[0009] A lifting arm device for a hanging equipment, the lifting arm device includes a track, the track includes a connected entry section and a lifting section, and is characterized in that the lifting arm device also includes a mounting seat, a baffle rod is hinged on the mounting seat, and a reset member is also provided on the mounting seat to allow the upper end of the baffle rod to extend from above the entry section.

[0010] Its working principle is: under the action of the reset member, the upper end of the baffle extends from the top of the entrance section. When the vehicle enters the entrance section, under the action of gravity, the roller of the vehicle rolls forward. When the roller passes the baffle, the roller presses the baffle down, and then enters the bottom of the lifting section. After the roller passes, under the action of the reset member, the baffle is reset, and the upper end of the baffle extends from the top of the entrance section again. Due to the obstruction of the lifting section, the vehicle swings back significantly and the roller retreats. At this time, the upper end of the baffle blocks the roller to prevent the vehicle from retreating. The baffle limits the rolling position range of the roller, so there will be no situation where the push block fails to push the roller of the vehicle and is empty or the push block just hits the roller.

[0011] In the above-mentioned lifting arm device of a hanging equipment, the reset part includes a torsion spring, a connecting shaft is provided on the mounting seat, the torsion spring is sleeved on the connecting shaft and is in a compressed state, one end and the other end of the torsion spring respectively abut against the mounting seat and the lower end of the barrier rod, the middle part of the barrier rod has a limiting shaft, and the limiting shaft abuts against the end of the mounting seat.

[0012] The torsion spring generates a thrust on the lower end of the barrier rod, causing the barrier rod to swing to a certain angle, after which the limit shaft of the barrier rod abuts against the end of the mounting seat, and then the barrier rod remains stationary, with the upper end of the barrier rod extending from above the station entry section.

[0013] When the vehicle enters the station section, the roller of the vehicle passes the barrier rod, and the roller presses the barrier rod down. After the roller passes, the torsion spring pushes the barrier rod to reset, and the limiting shaft of the barrier rod rests on the end of the mounting seat. The upper end of the barrier rod extends from the top of the station section. When the roller retreats, the barrier rod cannot swing in the opposite direction due to the limiting effect of the limiting shaft, so it can block the roller.

[0014] In the above-mentioned lifting arm device of a hanging equipment, there are two barrier rods and they are located on one side and the other side of the entrance section, there are two torsion springs, the two torsion springs are sleeved on the connecting shaft and are in a compressed state, one end and the other end of one torsion spring respectively rest on the mounting seat and the lower end of a barrier rod, and one end and the other end of the other torsion spring respectively rest on the mounting seat and the lower end of the other barrier rod.

[0015] The two blocking rods form a double blocking rod structure, which can block both sides of the roller to bring better blocking effect.

[0016] In the above-mentioned lifting arm device of the hanging equipment, the lower end portion of the blocking rod has a mounting groove, and one end portion of the torsion spring is located in the mounting groove and abuts against the bottom wall of the mounting groove.

[0017] The end of the torsion spring is located in the installation groove. This structure can prevent the end of the torsion spring from falling off the blocking rod, thereby improving the stability of the connection.

[0018] In the above-mentioned lifting arm device of a hanging equipment, the mounting seat is long and narrow, and has an accommodating cavity in the middle of the mounting seat. The bottom of the entry section is located in the accommodating cavity, and one side and the other side of the cavity wall of the accommodating cavity respectively have outward-extending convex edges, and the convex edges extend from one side and the other side of the entry section.

[0019] When the roller of the vehicle rolls, one side and the other side of the roller rest against the corresponding convex edges respectively. The two convex edges form a symmetrical structure of double tracks, which to a certain extent prevents the roller of the vehicle from unidirectional deviation during rolling.

[0020] In the above-mentioned lifting arm device of the hanging equipment, the mounting seat includes a main body, and the outer end portion of the main body has an inclined extending section, and the extending section gradually extends downward from the inside to the outside.

[0021] From inside to outside refers to from the end close to the main body to the end away from the main body, and the inclined extension section plays a guiding role, making it easier for the roller on the carrier to enter the mounting seat.

[0022] In the above-mentioned lifting arm device of the hanging equipment, the mounting seat is mounted on the bottom of the station entry section by screws.

[0023] The mounting base and the station entry section are fixed with screws, making assembly and disassembly easy.

[0024] The utility model also provides a hanging device, which includes any one of the above-mentioned lifting arm devices.

[0025] Compared with the prior art, the advantages of the present invention are as follows:

[0026] The stop rod of the lifting arm device can block the rollers of the vehicle to prevent the vehicle from falling back, avoid the situation where the push block fails to push the rollers of the vehicle and is empty or the push block just hits the rollers, so that the vehicle can enter the station stably and smoothly.
