Description

Technical Field

[0001] The invention relates to an annular circulation conveying device used for sofa production. Background Art

[0002] The assembly process of the finished sofa is to assemble various parts in various working positions on the production line in sequence until the assembly production is completed.

[0003] During the production of the existing sofa production line, after the parts are assembled through various processes to form the finished sofa, the finished sofa needs to be removed from the fixture and packaged, and then the fixture is manually moved to the initial position of the production line for recycling. It usually requires multiple workers to cooperate at the same time to complete the transportation work, which consumes a lot of manpower and time, and has the disadvantage of low production efficiency. In addition, in some processes, the sofa needs to be flipped to an appropriate angle to facilitate the work of the staff. For example, in the wiring process of the sofa with the electric adjustment backrest function, the bottom of the sofa needs to be flipped to face the staff; currently, it usually requires multiple workers to cooperate at the same time to flip the sofa to an appropriate angle, which consumes a lot of manpower and time, and also has the disadvantage of low production efficiency. Summary of the invention

[0004] According to one aspect of the present invention, in order to overcome at least one defect of the above-mentioned prior art, a ring-shaped circulating conveying device for sofa production is provided, which includes: a first conveying mechanism, including a sending transmission structure and a return transmission structure, the sending transmission structure and the return transmission structure are arranged in parallel, and the sending direction of the sending transmission structure is opposite to the return direction of the return transmission structure; a tooling structure for carrying the sofa, which is transmitted with the first conveying mechanism; two tooling transfer mechanisms, the sending transmission structure and the return transmission structure are arranged between the two tooling transfer mechanisms, and the tooling transfer mechanism is arranged to transfer the tooling structure between the sending transmission structure and the return transmission structure to form a circulating transmission on the first conveying mechanism; a sofa flipping mechanism arranged on the return transmission structure, and the sofa flipping mechanism drives the tooling structure to flip.

[0005] During the working process, in the initial state, a plurality of semi-finished sofa input positions are arranged beside the delivery transmission structure along the delivery direction, and the delivery transmission structure and the return transmission structure are started, so that the delivery transmission structure and the return transmission structure are respectively driven in their respective directions, and then a plurality of semi-finished sofas are placed on the tooling structure; when the tooling structure carrying the semi-finished sofas is transported by the delivery transmission structure to the tooling transfer mechanism arranged at the downstream end of the delivery transmission structure, the tooling transfer mechanism moves the tooling structure carrying the semi-finished sofas to the return transmission structure until it enters the sofa flipping mechanism, and the staff can control the sofa flipping mechanism to drive the tooling structure and the sofa on the tooling structure to flip until the semi-finished sofa is flipped to an angle suitable for wiring / connection operations and other processes that require the sofa to be flipped; when the operation is completed After the sofa is assembled, the staff operates the sofa flipping mechanism to flip it back to the initial state, the tooling structure moves back to the return transmission structure, the tooling structure carrying the sofa moves to the tooling transfer mechanism located at the downstream end of the transmission path of the return transmission structure, and the sofa is taken away by workers or other auxiliary equipment. Finally, the unloaded tooling structure is moved to the delivery transmission structure by the tooling transfer mechanism to return the unloaded tooling structure to the initial workstation located at the upstream end of the delivery transmission structure, so that the tooling structure forms a circular transmission on the conveying device and enters the next process cycle; in this way, in the assembly production process of the sofa, there is no need to manually move the tooling structure used to assemble the sofa, and there is no need to manually flip the semi-finished sofa to a tilt angle suitable for the operation, which saves manpower and time and has the characteristics of high production efficiency.

[0006] In some embodiments, the sofa flipping mechanism includes a body flipping bearing structure, a flipping track and a flipping driving device, wherein the flipping bearing structure is arranged on the transmission path of the return transmission structure; the flipping track is arranged between the body and the flipping bearing structure; the flipping driving device drives the flipping bearing structure, and the flipping bearing structure can produce relative flipping on the body through the flipping track.

[0007] In some embodiments, the flip track is arranged on the flip bearing structure, and a sliding member slidably matched with the flip track is provided on the machine body.

[0008] In this way, when working, the flipping drive device drives the flipping track to carry the flipping bearing structure and the tooling structure carrying the semi-finished sofa to produce a relative flipping action on the machine body through the sliding part, that is, it is realized that "the flipping bearing structure can produce a relative flipping on the machine body along the flipping track".

[0009] In some embodiments, the flipping drive device is disposed on the machine body; the flipping drive device includes a first driving motor, a first driving gear, and a driving rack extended along the trajectory of the flipping track; the first driving gear is disposed on the rotating shaft of the first driving motor, the driving rack is disposed on the flipping bearing structure, and the first driving gear is meshed and paired with the driving rack.

[0010] In this way, since the driving rack is arranged to extend along the trajectory of the flipping track and the flipping driving device is arranged on the machine body, when the first driving motor drives the first driving gear to rotate, the first driving gear will drive the flipping supporting structure to produce relative flipping movement on the machine body through the driving rack.

[0011] In some embodiments, the sofa flipping mechanism further includes a sofa locking mechanism disposed on the flipping bearing structure, and the sofa locking mechanism is used to lock the sofa supported by the flipping bearing structure.

[0012] In this way, the sofa is positioned on the flip bearing structure through the sofa locking mechanism to prevent the sofa from tipping over when the flip bearing structure is flipped relative to the machine body, without manual support, thereby improving production efficiency and operation safety.

[0013] In some embodiments, the sofa locking mechanism includes a first locking clamp, a second locking clamp and a third locking clamp, the first locking clamp is used to lock the sofa frame of the sofa supported by the flip bearing structure, the second locking clamp is used to lock the sofa seat / sofa armrest of the sofa supported by the flip bearing structure, and the third locking clamp is used to lock the sofa footrest of the sofa supported by the flip bearing structure.

[0014] In this way, during operation, the sofa frame and the sofa seat / armrest of the sofa are locked respectively by the two locking clamps, so that the sofa can be better positioned on the flip bearing structure to prevent the sofa from tipping over when the flip bearing structure is flipped relative to the body; and the third locking clamp can lock the sofa footrest to prevent the sofa footrest from popping out, so that the staff can carry out processing operations.

[0016] In this way, initially, the third transmission track of the tooling transfer mechanism arranged at the downstream end of the sending transmission structure is located in the first translation position and is aligned with the sending transmission structure; the third transmission track of the tooling transfer mechanism located at the downstream end of the transmission path of the return transmission structure is located in the second translation position and is aligned with the return transmission structure; when the tooling structure carrying the semi-finished sofa is transported by the sending transmission structure to the third transmission track of the tooling transfer mechanism arranged at the downstream end of the sending transmission structure, the translation drive structure drives the tooling structure carried by the third transmission track to move to the second translation position, and then the third drive structure drives the third transmission track to transmit in the same direction as the return transmission structure, then the tooling structure carrying the semi-finished sofa is moved from the return transmission structure to the flipping bearing structure of the sofa flipping mechanism, and then the staff operates and controls the flipping drive device to drive the flipping bearing structure to carry the semi-finished sofa and the tooling structure to produce relative flipping on the machine body along the flipping track until the semi-finished sofa is flipped to a position suitable for wiring / connection operations, etc. Other processes that require the sofa to be flipped over are performed at different angles; after the operation is completed, the staff operates and controls the flipping drive device to drive the flipping bearing structure to flip the sofa along the flipping track on the body back to the initial state, so that the flipping bearing structure is realigned with the transmission path of the return transmission structure, and then the tooling structure carrying the sofa is moved back to the return transmission structure, and the tooling structure carrying the sofa is moved to the tooling transfer mechanism located at the downstream end of the transmission path of the return transmission structure. The sofa is taken away by workers or other auxiliary equipment, and the translation drive structure of the tooling transfer mechanism located at the downstream end of the transmission path of the return transmission structure drives the third transmission track carrying the tooling structure in an unloaded state from the second translation position to the first translation position. At this time, the third transmission track is aligned with the delivery transmission structure, and then the third drive structure drives the third transmission track to transmit along the delivery direction to return the tooling structure in an unloaded state to the initial position located at the upstream end of the delivery transmission structure for reuse in each process.

[0017] In some embodiments, a control system and a tooling position detector are also included; wherein the tooling position detector is arranged corresponding to the third transmission track to monitor whether the tooling structure is located on the third transmission track; the tooling position detector, the third drive structure and the translation drive structure are all electrically connected to the control system.

[0018] In this way, when the tooling structure is transported by the feeding transmission structure to the third transmission track of the tooling transfer mechanism arranged at the downstream end of the feeding transmission structure, the tooling position detector sends an induction signal to the control system, and then the control system instructs the translational drive structure to drive the tooling structure carried by the third transmission track to move to the second translational position; when the tooling structure is transmitted to the third transmission track of the tooling transfer mechanism located at the downstream end of the transmission path of the return transmission structure, the tooling position detector sends an induction signal to the control system, and then the control system instructs the translational drive structure to drive the third transmission track carrying the tooling structure to move to the first translational position, and then the translational drive structure sends a signal that it has completed reaching the first translational position to the control system, and then the control system instructs the third drive structure to drive the third transmission track to transmit along the feeding direction, so as to return the tooling structure in an unloaded state to the initial workstation located at the upstream end of the feeding transmission structure, so as to be reused in each process; in this way, the control system instructs the third drive structure and the translational drive structure to complete the preset actions in sequence, thereby realizing the function of automated production.

[0020] In this way, when the tooling structure carrying the sofa is transmitted to the third transmission track of the tooling transfer mechanism located at the downstream end of the transmission path of the return transmission structure, the tooling position detector sends an induction signal to the control system, and then the control system instructs the transfer device to move the sofa. When the transfer device completes the clamping and transfer processes, it sends a completion instruction to the control system, and then the control system instructs the translational drive structure to drive the third transmission track to carry the tooling structure to the first translation position, and then the translational drive structure sends a signal that it has completed reaching the first translation position to the control system, and then the control system instructs the third drive structure to drive the third transmission track to transmit along the feeding direction, so as to return the tooling structure in an empty state to the initial workstation located at the upstream end of the feeding transmission structure for reuse in each process; in this way, the control system instructs the third drive structure, the translational drive structure and the transfer device to complete the preset actions in sequence, thereby realizing the function of automated production.

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0039] Figure 1 A circular circulating conveying device for sofa production according to an embodiment of the present invention is schematically shown.

[0040] like Figures 1 to 9As shown, the annular circulating conveying device for sofa production includes: a first conveying mechanism A1, including a sending transmission structure A11 and a return transmission structure A12, the sending transmission structure A11 and the return transmission structure A12 are arranged in parallel, and the sending direction of the sending transmission structure A11 is opposite to the return direction of the return transmission structure A12; a tooling structure C7, which is transmitted with the first conveying mechanism A1; two tooling transfer mechanisms B1, the sending transmission structure A11 and the return transmission structure A12 are arranged between the two tooling transfer mechanisms B1, and the tooling transfer mechanism B1 is arranged to transfer the tooling structure C7 between the sending transmission structure A11 and the return transmission structure A12 to form a circulating transmission on the first conveying mechanism A1; a sofa flipping mechanism arranged on the return transmission structure A12, and the sofa flipping mechanism drives the tooling structure C7 to flip.

[0041] Specifically, the sofa flipping mechanism includes a body C1, a flip bearing structure C2, a flip track C23 and a flip driving device C11. The flip bearing structure C2 is arranged on the transmission path of the return transmission structure A12 to carry the tooling structure C7; the flip track C23 is arranged between the body C1 and the flip bearing structure C2; ​​the flip driving device C11 drives the flip bearing structure C2, and the flip bearing structure C2 can generate relative flipping on the body C1 through the flip track C23.

[0042] During the working process, in the initial state, a plurality of process positions or semi-finished sofa input positions are arranged beside the delivery transmission structure A11 along the delivery direction, and each process position is provided with equipment or employees who complete the corresponding process. The delivery transmission structure A11 and the return transmission structure A12 are started, so that the delivery transmission structure A11 and the return transmission structure A12 are respectively installed with their respective direction transmissions, and then the semi-finished sofa is placed on the tooling structure C7. The tooling structure C7 carries the sofa frame and passes through each process position in turn along the delivery direction of the delivery transmission structure A11, and completes the corresponding process at each process position; when the tooling structure C7 carrying the semi-finished sofa After the tooling structure C7 is transported by the conveying transmission structure A11 to the tooling transfer mechanism B1 arranged at the downstream end of the conveying transmission structure A11, the tooling transfer mechanism B1 moves the tooling structure C7 carrying the semi-finished sofa to the return transmission structure A12. Since the flip bearing structure C2 is arranged on the transmission path of the return transmission structure A12, the return transmission structure A12 then moves the tooling structure C7 carrying the semi-finished sofa to the flip bearing structure C2 of the sofa flipping mechanism; then the staff operates and controls the flip driving device C11 to drive the flip bearing structure C2 to carry the semi-finished sofa and the tooling structure C7 along the flip track C23. The machine body C1 is relatively turned over until the semi-finished sofa is turned over to an angle suitable for wiring / connection operations and other processes that require the sofa to be turned over; after the operation is completed, the staff operates the turning drive device C11 to drive the turning bearing structure C2 to turn the sofa along the turning track C23 on the machine body C1 back to the initial state, so that the turning bearing structure C2 is aligned with the transmission path of the return transmission structure A12 again, and then the tooling structure C7 carrying the sofa is moved back to the return transmission structure A12, and the tooling structure C7 carrying the sofa is moved to the downstream end of the transmission path of the return transmission structure A12. The sofa is taken away by workers or other auxiliary equipment on the tooling transfer mechanism B1, and finally the unloaded tooling structure C7 is moved to the feeding transmission structure A11 by the tooling transfer mechanism B1 to return the unloaded tooling structure C7 to the initial workstation located at the upstream end of the feeding transmission structure A11, so that the tooling structure C7 forms a circular transmission on the conveying device and enters the next process cycle; in this way, in the assembly production process of the sofa, there is no need to manually move the tooling structure C7 used to assemble the sofa, and there is no need to manually flip the semi-finished sofa to a tilt angle suitable for the operation, which saves manpower and time and has the characteristics of high production efficiency.

[0043] like Figure 6 to Figure 9As shown in the present embodiment, the flip track C23 is arranged on the flip bearing structure C2, and a sliding member that is slidably adapted to the flip track C23 is arranged on the machine body C1. In this way, when working, the flip driving device C11 drives the flip track C23 to carry the flip bearing structure C2 and the tooling structure C7 carrying the semi-finished sofa to produce a relative flipping action on the machine body C1 through the sliding member, that is, it is realized that "the flip bearing structure C2 can be relatively flipped on the machine body C1 along the flip track C23". In other embodiments, the specific structure that realizes "the flip bearing structure C2 can be relatively flipped on the machine body C1 along the flip track C23" can also be appropriately adjusted according to actual conditions, for example: the flip track C23 can also be arranged on the machine body C1, and the sliding member can also be arranged on the flip bearing structure C2, and the sliding member supports the flip bearing structure C2 to be relatively flipped on the machine body C1 along the flip track C23.

[0044] like Figure 6 to Figure 9As shown, in this embodiment, the flip driving device C11 is arranged on the machine body C1; the flip driving device C11 includes a first driving motor C111, a first driving gear C112, and a driving rack C231 extending and arranged along the track direction of the flip track C23; the first driving gear C112 is arranged on the rotating shaft of the first driving motor C111, the driving rack C231 is arranged on the flip bearing structure C2, and the first driving gear C112 is meshed and matched with the driving rack C231. The extended profile of the driving rack C231 and the track of the flip track C23 form an "equidistant line". In this way, since the driving rack C231 is arranged to extend along the track direction of the flip track C23, and the flip driving device C11 is arranged on the machine body C1, when the first driving motor C111 drives the first driving gear C112 to rotate, the first driving gear C112 will drive the flip bearing structure C2 to generate a relative flipping motion on the machine body C1 through the driving rack C231. In other embodiments, the specific structure of the flip driving device C11 can also be adjusted appropriately according to actual conditions, as long as it can realize driving the flip track C23 to bring the flip bearing structure C2 to produce a relative flipping action on the body C1. More specifically, in this embodiment, the two flip tracks C23 are respectively arranged at the two ends of the flip bearing structure C2; ​​the sliding member includes two wheel sets C12, the wheel sets C12 include two first rollers C121 arranged at intervals, and the two wheel sets C12 are respectively arranged at the two ends of the body C1; the two flip tracks C23 correspond to the two wheel sets C12 one by one, and the flip tracks C23 roll with the corresponding two first rollers C121. In this way, by rolling cooperation between the flipping track C23 and the corresponding two first rollers C121, since the two first rollers C121 are arranged at intervals, the two first rollers C121 of the wheel pair group C12 jointly stably support the flipping track C23 in the direction of gravity. Since two flipping tracks C23 are respectively provided at the two ends of the flipping bearing structure C2, and two wheel pair groups C12 corresponding to the two flipping tracks C23 are respectively provided at the two ends of the body C1, the flipping track C23 is further stably supported in the horizontal direction, so that the flipping track C23 with the flipping bearing structure C2 can stably produce a relative flipping action on the body C1.

[0045] In this embodiment, the flip bearing structure C2 includes a transmission device C21 and a transmission drive device C22; the transmission drive device C22 is used to drive the transmission device C21 to transmit in the return direction. In the initial state, both ends of the transmission device C21 are aligned and connected with the return transmission structure A12. In this way, when the tooling structure C7 carrying the semi-finished sofa is transferred to the flip bearing structure C2, the transmission drive device C22 can drive the transmission device C21 to move the tooling structure C7 carrying the semi-finished sofa to a suitable position. At the same time, when the staff completes the work, the transmission drive device C22 can also drive the transmission device C21 to move the tooling structure C7 carrying the finished sofa to the return transmission structure A12, without the need for manual handling and adjustment, which further improves production efficiency. In detail, in this embodiment, the transmission device C21 includes a plurality of second rollers, which are arranged on the flip bearing structure C2 along the transmission direction of the transmission device C21; the transmission driving device C22 includes a second driving motor, a second driving gear, a synchronous gear belt and a plurality of third driving gears, wherein the plurality of third driving gears are respectively arranged to rotate coaxially with the plurality of second rollers, the plurality of third driving gears are meshed and matched with the synchronous gear belt, the second driving gear is arranged on the rotating shaft of the second driving motor, and the second driving gear is meshed and matched with the synchronous gear belt. In this way, when the staff operates the transmission driving device C22 to drive the transmission device C21 to transfer the semi-finished sofa to the appropriate position of the flip bearing structure C2, the second driving motor drives the second driving gear to roll with the synchronous gear belt, and then the synchronous gear belt drives the plurality of third driving gears to rotate synchronously, so as to drive the plurality of second rollers to rotate synchronously, so as to move the semi-finished sofa along the transmission direction. In other embodiments, the specific structures of the transmission device C21 and the transmission drive device C22 can be adjusted appropriately according to actual conditions, that is, as long as the semi-finished sofa can be moved and transferred to a suitable position of the flip bearing structure C2, it can be used.

[0046] like Figure 6 As shown, in this embodiment, it also includes a tooling locking mechanism C6 and a tooling locking driving structure C61, which are arranged on the flip bearing structure C2; ​​the tooling locking driving structure C61 is used to drive the tooling locking mechanism C6 to form a locking action in the transmission direction of the transmission device C21. In detail, the tooling locking mechanism C6 is a blocking plate, the tooling locking driving structure C61 is a fourth cylinder, and the blocking plate is arranged on the telescopic rod of the fourth cylinder. In this way, when the tooling structure C7 carrying the semi-finished sofa is transferred to a suitable position by the transmission device C21, the tooling locking driving structure C61 drives the tooling locking mechanism C6 to lock the tooling structure C7 carrying the semi-finished sofa in the transmission direction of the transmission device C21, so as to prevent the tooling structure C7 carrying the semi-finished sofa from moving, so as to facilitate the processing operation of the staff.

[0047] In this embodiment, the tooling transfer mechanism B1 includes a third transmission rail B11, a third drive structure and a translation drive structure B12; the third transmission rail B11 is provided with a first translation position aligned with the delivery transmission structure A11, and a second translation position aligned with the return transmission structure A12, and the translation drive structure B12 is configured to drive the third transmission rail B11 to move between the first translation position and the second translation position; the third drive structure is configured to drive the third transmission rail B11 to transmit along the delivery direction / return direction. In this way, initially, the third transmission track B11 of the tooling transfer mechanism B1 arranged at the downstream end of the sending transmission structure A11 is located in the first translation position, aligned with the sending transmission structure A11; the third transmission track B11 of the tooling transfer mechanism B1 located at the downstream end of the transmission path of the return transmission structure A12 is located in the second translation position, aligned with the return transmission structure A12; when the tooling structure C7 carrying the semi-finished sofa is transported by the sending transmission structure A11 to the third transmission track B11 of the tooling transfer mechanism B1 arranged at the downstream end of the sending transmission structure A11, the translation drive structure B 12 drives the tooling structure C7 carried by the third transmission track B11 to move to the second translation position, and then the third driving structure drives the third transmission track B11 to transmit in the same direction as the return transmission structure A12, so that the tooling structure C7 carrying the semi-finished sofa is moved from the return transmission structure A12 to the flip bearing structure C2 of the sofa flipping mechanism, and then the staff operates the flip driving device C11 to drive the flip bearing structure C2 to carry the semi-finished sofa and the tooling structure C7 along the flip track C23 on the body C1 to produce relative flipping, until the semi-finished sofa is flipped to a suitable position. After the operation is completed, the staff operates the flip driving device C11 to drive the flip bearing structure C2 to flip the sofa along the flip track C23 on the body C1 back to the initial state, so that the flip bearing structure C2 is aligned with the transmission path of the return transmission structure A12 again, and then the tooling structure C7 carrying the sofa is moved back to the return transmission structure A12, and the tooling structure C7 carrying the sofa is moved to the tooling transfer mechanism B1 located at the downstream end of the transmission path of the return transmission structure A12. , the sofa is taken away by workers or other auxiliary equipment, and the translation drive structure B12 of the tooling transfer mechanism B1 located at the downstream end of the transmission path of the return transmission structure A12 drives the third transmission track B11 to carry the tooling structure C7 in an empty state from the second translation position to the first translation position. At this time, the third transmission track B11 is aligned with the delivery transmission structure A11, and then the third drive structure drives the third transmission track B11 to transmit along the delivery direction to return the empty tooling structure C7 to the initial position located at the upstream end of the delivery transmission structure A11 for reuse in various processes. In other embodiments, the specific structure of the tooling transfer mechanism B1 can also be appropriately adjusted according to actual conditions.

[0048] like Figure 2 As shown, in this embodiment, a control system and a tooling position detector B13 are also included; wherein the tooling position detector B13 is arranged corresponding to the third transmission track B11 to monitor whether the tooling structure C7 is located on the third transmission track B11; the tooling position detector B13, the third driving structure and the translation driving structure B12 are all electrically connected to the control system.
