Description

Technical Field

[0001] This utility model relates to the field of garment hanging production lines, specifically to a hanging conveyor line lifting device. Background Technology

[0002] In the current operation of garment hanging production lines, some processes require the semi-finished garments from one production line to another. If this is done manually, it will result in a waste of overall efficiency. Therefore, a bridging station is needed to connect the two production lines to achieve automatic conveying of semi-finished garments.

[0003] Currently, common bridging stations generally adopt the following structure: the lower track is used to transport and store hanger assemblies; the segmented blocking assembly and the lowering blocking assembly use cylinder-driven claws to release and block hanger assemblies on the lower track; the segmented blocking assembly diverts hanger assemblies to the lowering blocking assembly; the lowering blocking assembly first blocks the hanger wheels of the hanger assembly with claws, and then senses the hanger wheels with photoelectric sensors, and then controls the cylinder to start and release the hanger wheels through the action of the connected claws. After the hanger reaches the corresponding position (generally after a set time after the claws release the hanger wheels), the lifting assembly is controlled to operate (the lifting assembly generally includes a conveyor belt and push blocks set on the conveyor belt), and the push blocks lift the hanger that has run to the output end of the lower track, and so on. The current bridging station has the following shortcomings: the control logic of the bridging station is complex and the response time is long. It requires first controlling the cylinder to start and releasing the hanger wheel through the action of the connected claws, and then waiting for a set time. After the hanger reaches the corresponding position, the lifting component is then controlled to operate. Furthermore, it is easy for errors in the control logic sequence or timing to affect the normal operation of the production line.

[0004] For example, Chinese Patent Publication No. CN215625145U, entitled "A Lifting Vehicle Release Mechanism and Lifting Equipment," also uses a cylinder-driven claw to release and block the clothes hanger assembly on the lower track, and it also has the aforementioned shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide a suspended conveyor lifting device that simplifies control logic, thereby shortening control response time and effectively avoiding the problem of production line operation being affected by control logic errors.

[0006] The technical solution of this utility model is:

[0007] A suspended conveyor line lifting device includes:

[0008] The lower track is arranged at an angle, including the output end;

[0009] The hanger assembly comprises a hanger wheel rolling along a lower track;

[0010] A lifting track is connected with the output end at a lower end;

[0011] A lifting assembly comprises a conveyor belt parallel to the lifting track and a push block fixed on the conveyor belt;

[0012] A linkage lower placing assembly is close to the output end and comprises:

[0013] A front clamping jaw and a rear paw are rotatably arranged, the rear paw comprises a trigger pressure rod matched with the push block and a paw matched with the hanger wheel, and the paw is located between the front clamping jaw and the output end;

[0015] The front clamping jaw comprises a blocking state and a release state; during the operation of the push block driven by the conveyor belt, the push block will abut against the trigger pressure rod and drive the trigger pressure rod and the paw to rotate downward, so as to drive the front clamping jaw to rotate through the connecting rod, so that the front clamping jaw is in the release state.

[0016] When the hanger wheel is rolled along the lower track to the output end by the front clamping jaw, the hanger wheel will contact the paw and drive the rear paw to rotate upward, so as to drive the front clamping jaw to rotate through the connecting rod, so that the front clamping jaw is in the blocking state. The specific work of the hanging type conveying line lifting device is as follows,

[0017] When the hanger wheel of the hanger assembly is blocked by the front clamping jaw, the conveyor belt drives the push block to move downward along the lifting track, during which the push block will abut against the trigger pressure rod and drive the trigger pressure rod and the paw to rotate downward, so as to drive the front clamping jaw to rotate through the connecting rod, so that the front clamping jaw is in the release state. At this time, the hanger wheel of the hanger assembly will convert the gravitational potential energy into kinetic energy and roll downward along the lower track under the action of the height difference. At the same time, the conveyor belt continues to drive the push block to pass the output end of the lower track and move upward, during which the push block will drive the hanger wheel that has reached the output end of the lower track to move upward along the lifting track, so as to realize the lifting of one hanger assembly.

[0018] The hanger wheel of the hanger assembly released by the front clamping jaw will roll downward along the lower track to the output end of the lower track, preparing for the lifting of the hanger assembly by the push block next time; at the same time, during this process, the hanger wheel will contact the paw and drive the rear paw to rotate upward, so that the front clamping jaw is driven to rotate through the connecting rod, so that the front clamping jaw returns to the blocking state to block the hanger wheel of the hanger assembly conveyed to the front clamping jaw, and the process is repeated.

[0019] Compared with the prior art that controls the starting of the cylinder, releases the hanger wheel through the action of the connected claw, controls the operation of the lifting assembly after the hanger assembly reaches the corresponding position, and lifts the hanger running to the output end of the lower track through the push block, the lifting device of the hanging type conveying line in the scheme directly controls the action of the conveying belt to release and lift the hanger assembly when the hanger wheel of the hanger assembly is blocked by the front claw through the linkage of the mechanical type lower release assembly and the push block of the lifting assembly, which saves the driving cylinder for driving the claw to rotate and the corresponding air pipe and control valve (saves cost), and correspondingly saves the time interval and delay between the release of the claw driven by the cylinder and the control of the operation of the lifting assembly after the hanger assembly reaches the corresponding position, so that the control logic can be simplified, the control response time can be shortened, and the problem that the normal operation of the production line is affected due to the error of the control logic can be effectively avoided.

[0037] Specific embodiment one, as shown in Figure 1 、 Figure 2 A kind of hanging type conveying line lifting device, including lower track 1, clothes hanger subassembly 2, lifting track 3, lifting subassembly 4 and linkage putting down subassembly 5, as shown in the drawing. Lower track 1 is inclinedly arranged. Lower track 1 includes output end 1.1, and in the embodiment, the output end 1.1 of lower track 1 refers to the end in lower point position in lower track 1.

[0038] Clothes hanger subassembly 2 includes clothes hanger wheel 2.1 and the clothes hanger on the connection in clothes hanger wheel 2.1.Clothes hanger wheel 2.1 rolls along lower track 1, to make clothes hanger subassembly 2 along lower track 1 conveying.

[0039] The lower end of the lifting track 3 is connected with the output end 1.1 of the lower track 1. In this embodiment, the lifting track 3 is arranged obliquely.

[0040] The lifting assembly 4 comprises a conveying belt 4.1 parallel to the lifting track 3 and push blocks 4.2 fixed on the conveying belt 4.1. The push blocks 4.2 are one or more, and the plurality of push blocks 4.2 are distributed equidistantly along the conveying belt 4.1. The conveying belt 4.1 is close to the lifting track 3, and the lower end of the conveying belt 4.1 is above the output end 1.1 of the lower track 1.

[0041] The linkage lowering assembly 5 is close to the output end 1.1. The linkage lowering assembly 5 comprises a mounting support, a front jaw 5.1, a rear pawl 5.2 and a connecting rod 5.3. The front jaw 5.1 is rotationally arranged on the mounting support. The rear pawl 5.2 is rotationally arranged on the mounting support. The front jaw 5.1 is above the lower track 1, and the rear pawl 5.2 is above the lower track 1. The rear pawl 5.2 is on the same side of the front jaw 5.1 and the output end 1.1 of the lower track 1. The rear pawl 5.2 comprises a trigger pressure rod 5.22 cooperating with the push block 4.2 and a pawl 5.21 cooperating with the hanger wheel 2.1. The pawl 5.21 is between the front jaw 5.1 and the output end 1.1. One end of the connecting rod 5.3 is hinged to the front jaw 5.1, and the other end of the connecting rod 5.3 is hinged to the rear pawl 5.2.

[0042] The front jaw 5.1 comprises a blocking state and a release state. During the driving of the push block 4.2 by the conveying belt 4.1, the push block 4.2 will abut against the trigger pressure rod 5.22 and drive the trigger pressure rod 5.22 and the pawl 5.21 to rotate downward, thereby driving the front jaw 5.1 to rotate through the connecting rod 5.3, so that the front jaw 5.1 is in the release state.

[0043] As shown in Figure 2 When the hanger wheel 2.1 is rolled along the lower track 1 by the front jaw 5.1 to the output end 1.1, the hanger wheel 2.1 will contact the pawl 5.21, and the rear pawl 5.2 will be rotated upward, thereby driving the front jaw 5.1 to rotate through the connecting rod 5.3, so that the front jaw 5.1 is in the blocking state.

[0044] The specific work of the hanging type conveying line lifting device of this embodiment is as follows,

[0045] When the hanger wheel 2.1 of the hanger assembly 2 is blocked by the front claw 5.1, the conveying belt 4.1 is actuated to drive the push block 4.2 to move down along the lifting track 3, in the process, the push block 4.2 will abut against the trigger pressure rod 5.22 and drive the trigger pressure rod 5.22 and the pawl 5.21 to rotate downward, thereby driving the front claw 5.1 to rotate through the connecting rod 5.3, so that the front claw 5.1 is in a released state. When the front claw 5.1 is in the released state, the hanger wheel 2.1 of the hanger assembly 2 will convert gravitational potential energy into kinetic energy and roll down along the lower track 1 under the action of the height difference. At the same time, the conveying belt 4.1 continues to drive the push block 4.2 to bypass the output end 1.1 of the lower track 1 from the lower end of the conveying belt 4.1 and run upward, in the process, the push block 4.2 will drive the hanger wheel 2.1 that has arrived at the output end 1.1 of the lower track 1 last time to lift along the lifting track 3, thereby realizing the lifting of one hanger assembly 2.

[0046] The hanger wheel 2.1 of the hanger assembly 2 released by the front claw 5.1 will roll down along the lower track 1 to the output end 1.1 of the lower track 1, preparing for the next time the push block 4.2 to lift the hanger assembly 2; at the same time, in the process, as shown in the figure, the hanger wheel 2.1 will contact the pawl 5.21 and make the rear pawl 5.2 rotate upward, thereby driving the front claw 5.1 to rotate through the connecting rod 5.3, so that the front claw 5.1 returns to the blocking state to block the hanger wheel 2.1 of the hanger assembly 2 conveyed to the front claw 5.1 subsequently, and so on. Figure 2

[0047] Compared with the prior art that uses a control cylinder to start and releases the hanger wheel 2.1 through the action of the connected claw, waits for the hanger assembly 2 to arrive at the corresponding position, and then controls the lifting assembly 4 to operate to lift the hanger running to the output end 1.1 of the lower track 1, the hanging type conveying line lifting device of the present scheme realizes the release and lifting of the hanger assembly 2 by directly controlling the action of the conveying belt 4.1 when the hanger wheel 2.1 of the hanger assembly 2 is blocked by the front claw 5.1 through the linkage of the mechanical type lowering assembly 5 and the push block 4.2 of the lifting assembly 4, which saves the driving cylinder for driving the claw to rotate and the corresponding air pipe and control valve (saves cost), and accordingly saves the time interval and delay between the release of the claw driven by the cylinder and the waiting for the hanger assembly 2 to arrive at the corresponding position before controlling the lifting assembly 4 to operate. Therefore, the control logic can be simplified, thereby being conducive to shortening the control response time and effectively avoiding the problem that the normal operation of the production line is affected due to the error of the control logic.

[0048] Specific embodiment two, as shown in Figure 1 Figure 2 ​​As shown, a hanging type conveying line lifting device comprises a lower track 1, a hanger assembly 2, a lifting track 3, a lifting assembly 4, a detection sensor 6 and a linkage lower placing assembly 5. The lower track 1 is arranged in an inclined manner. The lower track 1 comprises an output end 1.1. In the embodiment, the output end 1.1 of the lower track 1 refers to one end of the lower track 1 located at a low position.

[0049] The hanger assembly 2 comprises a hanger wheel 2.1 and a hanger connected to the hanger wheel 2.1. The hanger wheel 2.1 rolls along the lower track 1, so as to convey the hanger assembly 2 along the lower track 1.

[0050] The lower end of the lifting track 3 is connected to the output end 1.1 of the lower track 1. In the embodiment, the lifting track 3 is arranged in an inclined manner. It should be noted that the lifting track 3 can also be arranged in a vertical manner.

[0051] The lifting assembly 4 comprises a conveying belt 4.1 parallel to the lifting track 3 and a pushing block 4.2 fixed to the conveying belt 4.1. The pushing block 4.2 is one or more, and the plurality of pushing blocks 4.2 are arranged at equal intervals along the conveying belt 4.1. In the embodiment, the pushing block 4.2 is a plurality of pushing blocks 4.2 arranged at equal intervals along the conveying belt 4.1 (for example, the pushing block 4.2 is 2-6). The conveying belt 4.1 is close to the lifting track 3, and the lower end of the conveying belt 4.1 is located above the output end 1.1 of the lower track 1.

[0052] The linkage lower placing assembly 5 is close to the output end 1.1. The linkage lower placing assembly 5 comprises a mounting support, a front jaw 5.1, a rear pawl 5.2 and a connecting rod 5.3. The front jaw 5.1 is rotatably arranged on the mounting support. The rear pawl 5.2 is rotatably arranged on the mounting support. The front jaw 5.1 is located above the lower track 1, and the rear pawl 5.2 is also located above the lower track 1. The rear pawl 5.2 is located on the same side of the front jaw 5.1 and the output end 1.1 of the lower track 1. The rear pawl 5.2 comprises a trigger pressure rod 5.22 matched with the pushing block 4.2 and a pawl 5.21 matched with the hanger wheel 2.1. The pawl 5.21 is located between the front jaw 5.1 and the output end 1.1. The end of the pawl 5.21 extends obliquely downward to one side of the output end 1.1 of the lower track 1. One end of the connecting rod 5.3 is hinged to the front jaw 5.1, and the other end of the connecting rod 5.3 is hinged to the rear pawl 5.2.

[0053] The front jaw 5.1 comprises a blocking state and a release state. In the blocking state, the hanger wheel 2.1 is blocked by the front jaw 5.1 when rolling along the lower track 1 to the front jaw 5.1. In the release state, the hanger wheel 2.1 rolling along the lower track 1 to the front jaw 5.1 is released.

[0054] In the embodiment, the front clamping jaw 5.1 comprises a blocking jaw 5.11, the end of the blocking jaw 5.11 extends obliquely downward to the side away from the rear pushing jaw 5.2. When the front clamping jaw 5.1 is in the blocking state, the hanger wheel 2.1 rolling down along the lower track 1 will be blocked by the blocking jaw when rolling to the front clamping jaw 5.1. When the front clamping jaw 5.1 is in the releasing state, the hanger wheel 2.1 rolling down along the lower track 1 will be released (not blocked by the blocking jaw) when rolling to the front clamping jaw 5.1.

[0055] During the operation of the transmission belt 4.1 driving the pushing block 4.2, the pushing block 4.2 will abut against the trigger pressing rod 5.22 and drive the trigger pressing rod 5.22 and the pushing jaw 5.21 to rotate downward, thereby driving the front clamping jaw 5.1 to rotate through the connecting rod 5.3, so that the front clamping jaw 5.1 is in the releasing state. Specifically, during the operation of the transmission belt 4.1 driving the pushing block 4.2, the pushing block 4.2 will abut against the trigger pressing rod 5.22 and drive the trigger pressing rod 5.22 and the pushing jaw 5.21 to rotate downward, thereby driving the blocking jaw of the front clamping jaw 5.1 to rotate upward through the connecting rod 5.3, so that the front clamping jaw 5.1 is in the releasing state.

[0056] As shown in Figure 2 When the hanger wheel 2.1 is rolled along the lower track 1 to the output end 1.1 by the front clamping jaw 5.1, the hanger wheel 2.1 will contact the pushing jaw 5.21 and make the rear pushing jaw 5.2 rotate upward, thereby driving the front clamping jaw 5.1 to rotate through the connecting rod 5.3, so that the front clamping jaw 5.1 is in the blocking state. Specifically, when the hanger wheel 2.1 is rolled along the lower track 1 to the output end 1.1 by the front clamping jaw 5.1, the hanger wheel 2.1 will contact the pushing jaw 5.21 and make the rear pushing jaw 5.2 rotate upward, thereby driving the blocking jaw of the front clamping jaw 5.1 to rotate downward through the connecting rod 5.3, so that the front clamping jaw 5.1 is in the blocking state.

[0057] The detection sensor 6 is arranged on the mounting support. When the hanger wheel 2.1 is blocked on the lower track 1 by the front clamping jaw 5.1, the hanger wheel 2.1 will trigger the detection sensor 6. In the embodiment, the detection sensor 6 is an optical switch. Of course, the detection sensor 6 can also be other detection sensors on the market.

[0058] The specific work of the hanging type conveying line lifting device of the embodiment is as follows,

[0059] In the initial state, the front clamping jaw 5.1 is in the blocking state.

[0060] When the hanger wheel 2.1 of the hanger assembly 2 is blocked by the front pawl 5.1, the hanger wheel 2.1 will trigger the detection sensor 6, at this time, the transmission belt 4.1 is in action, driving the push block 4.2 to move down along the lifting track 3, in this process, the push block 4.2 will abut against the trigger pressure rod 5.22 and drive the trigger pressure rod 5.22 and the pawl 5.21 to rotate downward, thereby driving the front pawl 5.1 to rotate through the connecting rod 5.3, so that the front pawl 5.1 is in the release state. When the front pawl 5.1 is in the release state, the hanger wheel 2.1 of the hanger assembly 2 will convert the gravitational potential energy into kinetic energy under the action of the height difference and roll down along the lower track 1 from the front pawl 5.1. At the same time, the transmission belt 4.1 continues to drive the push block 4.2 to bypass the output end 1.1 of the lower track 1 from the lower end of the transmission belt 4.1 and run upward, in this process, the push block 4.2 will drive the hanger wheel 2.1 that reached the output end 1.1 of the lower track 1 last time to lift along the lifting track 3, thereby realizing the lifting of a hanger assembly 2.

[0061] The hanger wheel 2.1 of the hanger assembly 2 released by the front pawl 5.1 will roll down along the lower track 1 to the output end 1.1 of the lower track 1, preparing for the next push block 4.2 to lift the hanger assembly 2; at the same time, in this process, the hanger wheel 2.1 will contact the pawl 5.21 and make the rear pawl 5.2 rotate upward, thereby driving the front pawl 5.1 to rotate through the connecting rod 5.3, so that the front pawl 5.1 returns to the blocking state to block the hanger wheel 2.1 of the hanger assembly 2 conveyed to the front pawl 5.1 subsequently, and so on.

[0062] In order to prevent the last hanger assembly 2 from reaching the output end 1.1 of the lower track 1 and not being lifted due to the detection sensor 6 not detecting the hanger wheel 2.1. During the operation of the transmission belt 4.1, when the detection sensor 6 does not detect the hanger wheel 2.1, the transmission belt 4.1 continues to run for 1-2 rounds and then stops running.

[0063] Compared with the prior art that controls the starting of the cylinder, releases the hanger wheel 2.1 through the action of the connected claw, controls the operation of the lifting assembly 4 after the hanger assembly 2 reaches the corresponding position, and lifts the hanger running to the output end 1.1 of the lower track 1 through the push block 4.2, the lifting device of the hanging type conveying line in the scheme is linked with the push block 4.2 of the lifting assembly 4 through the mechanical linkage lower release assembly 5. When the hanger wheel 2.1 of the hanger assembly 2 is blocked by the front claw 5.1, the conveying belt 4.1 can be directly controlled to release and lift the hanger assembly 2, which saves the driving cylinder for driving the claw to rotate and the corresponding air pipe and control valve (saves cost), and the time interval and delay between the release of the cylinder driving claw and the control of the operation of the lifting assembly 4 after the hanger assembly 2 reaches the corresponding position are saved. Therefore, the control logic can be simplified, thereby being beneficial to shortening the control response time and effectively avoiding the problem that the normal operation of the production line is affected due to the error of the control logic.

[0064] In the embodiment, the lifting device of the hanging type conveying line further comprises a rack and an upper track (not shown in the figure). The lower end of the lifting track 3 is connected to the output end 1.1 of the lower track 1 through a circular arc transition. The upper end of the lifting track 3 is connected to the input end of the upper track. The upper track is inclined and distributed, and the input end of the upper track is located at one end of the high point of the upper track. When the conveying belt 4.1 drives the push block 4.2 to lift the hanger wheel 2.1 along the lifting track 3 to the specified position (i.e. the upper end of the lifting track 3), the hanger wheel 2.1 will be output to the upper track and output along the upper track.

[0065] Further, as shown in Figure 1 、 Figure 2 , the mounting support comprises a front support 5.4 and a rear support 5.5. The front support 5.4 is fixed on the rack. The rear support 5.5 is located on the same side of the front support 5.4 as the output end 1.1. The front claw 5.1 is rotatably arranged on the front support 5.4, and the rear claw 5.2 is rotatably arranged on the rear support 5.5. The detection sensor 6 is also arranged on the front support 5.4. In this way, actual processing and installation are facilitated.

[0066] Further, as shown in Figure 1 、 Figure 2As shown, the front support 5.4 has a C-shaped cross-section and includes a top plate, a bottom plate, and connecting side plates. A channel is formed between the top and bottom plates of the front support 5.4. The lower rail 1 passes through this channel and is bolted to the bottom plate. A support is provided on the top plate of the front support 5.4, and the front pawl 5.1 is rotatably mounted on this support. An opening is also provided on the top plate of the front support 5.4, and the blocking pawl of the front pawl 5.1 is located within the main support channel. The front pawl 5.1 also includes a handle, which passes through the opening of the front support 5.4 and is located above the top plate. The connecting rod 5.3 is located above the front support 5.4.

[0067] The rear support 5.5 has a C-shaped cross-section. The rear support 5.5 includes a top plate, a bottom plate, and connecting side plates. A channel is formed between the top and bottom plates of the rear support 5.5. The lower rail 1 passes through the channel and is bolted to the bottom plate of the rear support 5.5. A support is provided on the top plate of the rear support 5.5, and the rear shifter 5.2 is rotatably mounted on the support on the rear support 5.5. An opening is also provided on the top plate of the rear support 5.5, and the shifter 5.21 of the rear shifter 5.2 is located within the main support channel. The rear shifter 5.2 also includes a handle, which passes through the opening of the rear support 5.5 and is located above the top plate. The connecting rod 5.3 is located above the rear support 5.5.

[0068] Furthermore, a suspended conveyor lifting device also includes a limiting guide rail. The limiting guide rail is disposed on the upper surface of the lower rail 1 and near the output end 1.1. In this embodiment, the limiting guide rail is bolted to the upper surface of the lower rail 1. The limiting guide rail extends along the lower rail 1. The upper surface of the limiting guide rail is a guide slope, one end of which is close to the upper surface of the lower rail 1, and the other end of which extends downward along the lower rail 1, forming a limiting step between the guide slope and the lower rail 1. The limiting step is close to the output end 1.1 of the lower rail 1. When the hanger wheel 2.1 rolls to the output end 1.1 of the lower rail 1, the hanger wheel 2.1 is restricted between the limiting step and the output end 1.1 of the lifting rail 3. Thus, when the hanger wheel 2.1 rolls to the output end 1.1 of the lower track 1, it will be restricted between the limiting step and the output end 1.1 of the lifting track 3, preventing the hanger wheel 2.1 from rolling back after contacting the lifting track 3, so that the push block 4.2 of the subsequent lifting component 4 can smoothly lift the hanger wheel 2.1 that has rolled to the output end 1.1 of the lower track 1.

[0069] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
