For some large format products, such as mattress, bed sheet, quilt cover, quilt, etc., due to the large format of the material, if the workers manually clamp and connect, the operation is laborious and the operation efficiency is not high. The large format is referred to the size of ordinary clothes, which is larger than the size of such clothes. When a single worker clamps and connects, the operation is inconvenient.

The adjustable mattress driving mechanism of the present application is more reliable in self-locking, has a longer service life of the motor, is more stable and reliable in work, and is convenient to disassemble, debug and maintain.

[0004] The structure of the driving device is relatively complex, and when driving the mattress, it is easy to cause stubborn wrinkles on the surface fabric of the mattress, which cannot well adapt to the driving requirements of the mattress. SUMMARY

[0005] The technical problem to be solved by the present application is to provide an automatic feeding system for large format material, which can well adapt to the automatic feeding of large format material and cause little damage to the surface of the material.

[0006] The technical solution for solving the technical problem is an automatic feeding system for large format material, which is used for clamping and connecting large format material to a hanger in a hanging system. The structure comprises a workbench, the material is used to be laid on the table top of the workbench, a support and a rack are arranged at the position of the workbench, the support and the rack both extend to the upper side of the workbench, the rack is arranged close to the hanging system, the hanger has a plate type clamping structure, and the automatic feeding system further comprises:

[0007] The opening and closing device is arranged on the frame and located at the upper side of the workbench, comprising a pushing mechanism fixed on the frame, a pushing member connected to the pushing mechanism, and a plug-in structure connected to the pushing member, which is used to act on the ear plate of the hanging bracket to open the plate clamp under the driving of the pushing mechanism.

[0008] The driving mechanism is arranged on the bracket and located at the upper side of the workbench and is in driving connection with the driving motor, comprising a driving wheel, a driving belt connected to the driving wheel, and a straight section with a certain length formed at the bottom of the driving mechanism, which is used to drive the material to translate on the workbench towards the opening and closing device in a way of abutting against the surface of the material to realize the clamping of the plate clamp on the material.

[0009] The hanging bracket is applied in the hanging system as a carrier to realize the hanging and conveying of the material, semi-finished product or finished product in a clamping way. Corresponding to the material with large area, the clamping structure on the hanging bracket generally comprises a fan-shaped clamp plate arranged in an elastic hinged way. When the driving device drives the material, the straight section on the driving belt mainly realizes the driving of the material in a way of static friction, so that the material translates on the workbench towards the opening and closing device. Under the action of the pushing mechanism, the plug-in structure abuts against the ear plate position, so that the plate clamp can be turned to open to form a clamping opening. After the material enters the clamping opening, the pushing mechanism is retracted, the plate clamp is reversed to close the clamping opening, and the plate clamp abuts against the material to realize the clamping of the material. When clamping the material, the hanging bracket is still connected to the hanging system, which can be limited by arranging a limiting structure on the workbench or the frame, or the hanging bracket can be manually placed in the correct position so that the plug-in structure on the pushing member can accurately abut against the ear plate on the plate clamp.

[0010] Further, the driving mechanism further comprises a semi-closed housing, the driving wheel and the driving belt are arranged in the housing, the lower side of the housing is open, and the straight section is located at the opening and protrudes downward. By arranging the housing, an installation base is provided for other structures in the driving mechanism, the structure of the driving mechanism is compact, and other structures will not affect the material when the driving mechanism works.

[0011] Further, a plurality of feeding wheels are arranged on one side of the driving wheel in the housing, the wheel shafts of the feeding wheels are bridged on the opposite two side walls of the housing; the outermost feeding wheel is higher than the inner feeding wheel, and the driving belt is connected to the feeding wheels, the driving belt protrudes outside the housing at the position of the feeding wheel, thereby forming a feeding port at the position of the feeding wheel. By arranging the feeding wheel, on the one hand, the feeding port with relatively large size is formed to facilitate the interaction between the material and the driving belt; on the other hand, the inner feeding wheel provides support for the driving belt, so that the driving belt can stably interact with the material surface. If the feeding port is the discharge end of the material, it can also adapt to the driving of the driving belt on the material. The passive wheel can be arranged in the housing to form a relatively large straight line, thereby stably driving the material. Of course, the straight line can be formed between the driving wheel and the feeding wheel, or between the passive wheel and the feeding wheel.

[0012] Further, one driving motor corresponds to two sets of driving mechanisms arranged in parallel in the horizontal direction, the rotating shaft connected to the driving motor is bridged on the two sets of driving mechanisms, the driving wheels in the two sets of driving mechanisms are fixedly connected to the two ends of the rotating shaft, and the two sets of driving mechanisms are supported by the rotating shaft. By arranging the double driving belt structure, the material can be stably driven. Moreover, the two sets of driving mechanisms are supported by the rotating shaft, the driving mechanism has a certain degree of freedom, can well adapt to the material surface, and facilitates the stable contact between the driving belt and the material. The driving mechanism can also be properly supported by arranging the tension spring between the housing and the support to prevent the driving mechanism from moving excessively on the rotating shaft.

[0013] Further, the driving motor is connected to the outer end of the cantilever, the inner end of the cantilever is hinged to the support, and a power mechanism is arranged between the support and the cantilever to lift the outer end of the cantilever. By arranging the cantilever, the lifting of the driving mechanism can be effectively realized, and the driving requirement for materials with different thicknesses can be better adapted.

[0014] Further, the driving mechanism includes a transverse driving mechanism and a longitudinal driving mechanism, and the movement directions of the driving belts in the longitudinal driving mechanism and the transverse driving mechanism are perpendicular. The longitudinal driving mechanism is used to realize the forward movement of the material, and the transverse driving mechanism is used to adjust the position of the material in the width direction of the workbench, so that the clamping position of the hanger to the material is reasonable.

[0015] Further, the pushing piece includes a movable frame, the movable frame includes two side plates arranged in parallel, the movable frame is pivoted to a fixed block, the fixed block is connected to the pushing mechanism, and the plug-in structure is bridged on the two side plates. The structure of the pushing piece is simple, can stably contact the plate clamp on the hanger, and facilitates the force application. The transmission connection between the pushing piece and the pushing mechanism can be effectively realized by the fixed block.

[0016] Further, the plug-in structure is a plug-in rod, one end of the plug-in rod is rotatably connected to one side plate, and the other end of the plug-in rod is elastically abutted on the other side plate. The rod-type plug-in rod can be well adapted to the structure of the ear plate of the plate clamp, and is conducive to stably applying force to the plate clamp. The connection mode between the plug-in rod and the two side plates also makes the plug-in rod easy to be separated from the ear plate of the plate clamp.

[0017] Further, the pushing mechanism is provided with a sliding rail arranged along the movement direction of the pushing piece, and a sliding block is slidably arranged on the sliding rail, one end of the connecting piece is fixedly connected to the sliding block, and the other end is connected to the fixed block. Through the arrangement of the sliding rail and the connecting piece, the movement position of the pushing piece is accurate under the driving of the pushing mechanism, which is helpful for the stable cooperation of the plug-in rod and the plate clamp.

[0018] Further, a positioning piece is arranged on the sliding block, the positioning piece extends towards the lower side of the pushing mechanism, the lower end of the positioning piece is bent, and a positioning opening is arranged on the bent portion of the lower end of the positioning piece. Through the positioning opening on the positioning piece, relative positioning is performed with the corresponding structure on the hanging system, so that the pushing mechanism can be installed to the accurate position, and after the pushing mechanism drives the pushing piece to move, the plug-in structure on the pushing piece can be accurately inserted into the position of the ear plate of the plate clamp, thereby improving the working stability of the opening and closing device.

[0019] Compared with the prior art, the driving device has the beneficial effects that: the driving device is used for driving large-format materials, reduces manual operation when the large-format materials are hung and placed on the rack, can well adapt to the hanging and placing of the large-format materials on the rack, and has high operation efficiency. By forming a linear portion with a certain size on the driving belt, the linear portion on the driving belt is small in damage to the surface of the material on the basis of meeting the driving requirements of the large-format material, and the surface of the material is well protected.

[0020] The opening and closing device can make the plate clamp on the hanging frame rotate and open to form a clamping opening, after the material is translated on the workbench and enters the clamping opening, the opening and closing device retracts the plate clamp to reset, and the clamping of the material can be realized, and the automatic placing of the material is completed. In the clamping process of the material, the human participation is small, the labor cost can be effectively reduced, and the working efficiency is improved. Through the action of the plug-in structure on the position of the ear plate of the plate clamp on the hanging frame, the action position is reasonable, the force applied to the plate clamp can be well adapted, and the plate clamp can be smoothly rotated.

DETAILED DESCRIPTION

[0031] In combination with the drawings of the specification, the automatic large-format material shelving system is used to clamp large-format materials to hangers in a hanging system, and the hangers will carry the materials on the hanging system for subsequent processing procedures.

[0032] A plurality of hangers need to be provided on the hanging system, and the hangers involved are provided with plate clamping structures, i.e. Figure 9The main structure of the plate clamping structure is similar to the hanger structure shown in the figure, and includes a plate clamp 22 approximately in the shape of a sector, which is hinged to the hanger body 21 and abuts against the hanger body 21 under the action of an elastic member, thereby forming the plate clamping structure. In the figure, an ear plate 221 extending upward is integrally formed at the upper corner of the plate clamp 22. When manually operating, the plate clamp 22 is rotated to open the plate clamping structure by applying an external force to the ear plate 221 with a finger. After the finger is released, the plate clamp 22 is rotated under the action of the elastic member to close the plate clamping structure, thereby clamping the material entering the plate clamping structure.

[0033] The structure of the upper hanger system includes a workbench 1 having a work plane on which the material is horizontally laid. A support 2 is arranged at the position of the workbench 1, and in the figure, the support 2 is supported by the ground. The upper end of the support 2 extends to the upper side of the workbench 1. The support 2 can also be a hanging support supported by the roof of a factory building, and the lower end of the hanging support extends to the upper side of the workbench 1. A driving device for driving the material to translate on the workbench is arranged on the support 2, and the driving device includes a driving mechanism 3 arranged on the support 2 and located at the upper side of the workbench 1. The driving mechanism 3 is in transmission connection with a driving motor 36, and the driving motor 36 provides power for the operation of the driving mechanism 3. The driving mechanism 3 includes a driving wheel 38 in transmission connection with the driving motor 36. Under the action of the driving motor 36, the driving wheel 38 rotates, and a driving belt 32 is connected to the driving wheel 38 and moves with the driving wheel 38. The driving belt 32 has a straight portion 321 with a certain length at the bottom of the driving mechanism 3. The length of the straight portion 321 is generally several to ten or twenty centimeters, which can be determined according to the characteristics of the material to be driven. When driving the material, the straight portion 321 abuts against the upper surface of the material and moves under the action of the driving wheel 38, thereby driving the material to translate on the workbench 1 toward the direction of the hanger. At this time, the clamping structure on the hanger is in an open state, and the edge of the material directly enters the clamping structure. After the clamping structure is closed, the clamping of the material by the hanger is completed.

[0034] In order to achieve compactness, the driving mechanism 3 further includes a semi-enclosed housing 31 approximately in the shape of a triangle. The driving wheel 38 and the transmission belt are arranged in the housing 31, and the lower side of the housing 31 is open. The straight portion 321 is located at the opening, and the straight portion 321 of the driving belt 32 protrudes downward to the outside of the housing 31, thereby enabling the straight portion 321 to stably abut against the surface of the material.

[0035] A plurality of feed wheels 30 are arranged in the shell 31 on one side of the driving wheel 38, and three feed wheels 30 are shown in the figure. The wheel shafts of the three feed wheels 30 are arranged in parallel and bridged on the opposite side walls of the shell 31. Among the feed wheels 30, the outermost feed wheel 30 is arranged higher than the inner feed wheels 30, and the driving belt 32 is connected to the feed wheels 30. The driving belt 32 protrudes outside the shell 31 at the positions of the feed wheels 30. Due to the arrangement position of the outermost feed wheel 30, a feed port is formed at the position of the feed wheel 30, which is spaced from the workbench 1 from large to small, so that the material can smoothly enter the space between the driving belt 32 and the workbench 1, and well adapt to the driving requirements of the material. The passive wheel 37 is arranged in the shell 31 on the other side of the driving wheel 38. The wheel shaft of the passive wheel 37 is bridged on the opposite side walls of the shell 31, and the driving belt 32 is connected to the passive wheel 37. The straight part 321 is formed between the passive wheel 37 and the feed wheel 30. In order to facilitate tensioning of the driving belt 32, the tensioning wheel 39 is also arranged in the shell 31. The wheel shaft of the tensioning wheel 39 is also bridged on the opposite side walls of the shell 31. The driving wheel 38, the passive wheel 37, the feed wheel 30 are located on the inner side of the driving belt 32, and the tensioning wheel 39 is located on the outer side of the driving belt 32. The outer peripheral surface of the tensioning wheel 39 abuts against the outer surface of the driving belt 32. The driving belt 32 is arranged in a curved shape in the shell 31 through the arrangement positions of the driving wheel 38, the passive wheel 37, the feed wheel 30 and the tensioning wheel 39 in the shell 31. Figure 3 As shown in the figure, the wheel shafts of the wheel structures include column pipes 7, the two ends of the column pipes 7 abut against the inner wall surfaces of the opposite side walls of the shell 31, so that the installation space width inside the shell 31 is maintained. Screws are respectively screwed at the two ends of the column pipes 7 and pass through the corresponding side walls of the shell 31, so as to realize the stable support of the column pipes 7 to the side walls of the shell 31, and facilitate the installation and disassembly of the shell 31.

[0036] A driving motor 36 corresponds to two sets of driving mechanisms 3, the two sets of driving mechanisms 3 are arranged in parallel in horizontal direction, the straight line parts 321 of the driving belts 32 in the two sets of driving mechanisms 3 are parallel. A rotating shaft 34 which is in transmission connection with the driving motor 36 is bridged on the two sets of driving mechanisms 3, that is, the two ends of the rotating shaft 34 respectively extend into the corresponding housings 31, the driving wheels 38 in the two sets of driving mechanisms 3 are fixed on the two ends of the rotating shaft 34. The side walls of the housings 31 are generally fixed with hollow support seats and bearings, the rotating shaft 34 is rotatably penetrated through the bearings, the housings 31 are supported on the rotating shaft 34 through the support seats and bearings. Of course, the two sets of driving mechanisms 3 can also be directly supported on the rotating shaft 34 through the driving belts 32 and the driving wheels 38. In order to adapt to this structure, a tension spring 6 is arranged between the support 2 and the housing 31, the two ends of the tension spring 6 are respectively connected to the housing 31 and the support 2, the tension spring 6 is in a stretched state, and the stretching degree of the tension spring 6 will generally change in the actual working process.

[0037] The driving motor 36 is fixed on the outer end of the cantilever 33, the hinged column 4 is fixed on the inner end of the cantilever 33, the hinged ring 5 is fixed at the corresponding position of the support 2, the hinged column 4 is rotatably inserted into the hinged ring 5, and the inner end of the cantilever 33 is hinged on the support 2. A power mechanism is arranged between the support 2 and the cantilever 33, the power mechanism promotes the outer end of the cantilever 33 to lift. The power mechanism shown in the figure is a power cylinder 35, the cylinder body of the power cylinder 35 is movably connected to the support 2, the piston rod in the power cylinder 35 is movably connected to the cantilever 33, and the outer end of the cantilever 33 can be lifted under the action of the power cylinder 35. Of course, the power mechanism can also be a screw rod mechanism.

[0038] The driving mechanism 3 includes the transverse driving mechanism 23 and the longitudinal driving mechanism 13, the movement directions of the driving belts 32 in the longitudinal driving mechanism 13 and the transverse driving mechanism 23 are perpendicular. The longitudinal driving mechanism 13 is two groups, the transverse driving mechanism 23 is one group, the two groups of longitudinal driving mechanisms 13 are arranged in straight line, and the movement directions of the driving belts 32 on the two groups of longitudinal driving mechanisms 13 are the same. The longitudinal driving mechanism 13 is used for driving the material to move in the length direction of the workbench 1, so as to realize the movement of the material to the direction of the hanger. The upstream side longitudinal driving mechanism 13 can also adjust the longitudinal position of the material on the workbench 1, so that the material smoothly enters the downstream position of the longitudinal driving mechanism 13 to be driven by the downstream side longitudinal driving mechanism 13. The transverse driving mechanism 23 is used for driving the material to move in the width direction of the workbench 1, so as to make the material in the central position of the width direction of the workbench 1. Generally, the transverse driving mechanism 23 is started first to adjust the position of the material on the workbench 1, of course, whether the transverse driving mechanism 23 works or not is not necessary in production, and it is only started when the position of the material needs to be adjusted.

[0039] In the operation, a worker usually stands beside the workbench 1 to control the corresponding driving mechanism 3. The control buttons of the corresponding driving mechanism 3 can be integrated on a controller, which is controlled by the worker according to the actual working condition. The driving belt 32 in the transverse driving mechanism 23 can have two opposite directions of movement, which can be determined according to the position of the material on the workbench 1. In the actual operation process, the position of the material on the workbench 1 in the width direction has no accurate requirement, which is mainly determined by the worker according to experience. For materials of different thicknesses, the interval between the driving mechanism 3 and the workbench 1 can be adjusted by the power mechanism, or when the driving belt 32 is wound around the material surface, the driving mechanism 3 can be separated from the material surface by the power mechanism, and after the material is flattened, the driving mechanism 3 is lowered to normally drive the material.

[0040] In order to realize the automatic feeding of the material, the opening and closing device is arranged near the hanging system position, which acts on the plate clamp 22 on the hanging bracket to make the plate clamp 22 deflect to form a clamping opening. The material is translated on the workbench 1 under the pushing of the driving device, and enters the clamping opening. After the opening and closing device releases the action on the plate clamp 22, the plate clamp 22 resets to realize the clamping of the material. When the opening and closing device acts on the plate clamp structure on the hanging bracket, the hanging bracket is hung on the plate driving chain in the hanging system. In order to ensure the accuracy of the action position, a position sensor 11 is arranged outside the opening and closing device, which is used to sense the conveying position of the plate driving chain to the hanging bracket. After the hanging bracket is conveyed to the position, the plate driving chain stops moving, the hanging bracket is in place, and then the opening and closing device is started to act on the plate clamp 22. After the material is clamped by the plate clamp 22, the worker can operate the control switch to start the plate driving chain, and the hanging bracket with the material is conveyed to the loop track of the hanging system for subsequent processing of the material.

[0041] A rack 9 is arranged at the position of the workbench 1, and the rack 9 shown in the figure is supported by the floor in the factory building. The rack 9 extends to the upper side of the workbench 1, and is closer to the hanging system relative to the aforementioned support 2. The rack 9 can also be integrated with the aforementioned support to make the whole firm. The structure of the opening and closing device includes a pushing mechanism, which is fixed to the upper end of the rack 93 and is located at the upper side of the workbench 1. A mounting rack 10 is built by some hollow profiles and several connecting pieces, and is fixed to the upper end of the rack 9. The mounting rack 10 connects the pushing mechanism and the rack 9, and makes the pushing mechanism in a proper spatial position. The mounting position of the opening and closing device can be determined according to actual needs, but in order to quickly and accurately install the opening and closing device, a positioning piece 13 is arranged on the sliding block 15, which extends to the lower side of the pushing mechanism. The lower end of the positioning piece 13 is bent, and a positioning hole is arranged on the bent part of the lower end of the positioning piece 13.

[0042] After the plate-type driving chain transports the empty hanging bracket to the position, the lower end of the hanging bracket leans against the workbench 1. The position of the lower end of the hanging bracket on the workbench 1 can be manually adjusted by workers, or the position of the lower end of the hanging bracket can be adjusted by arranging some position adjusting mechanisms on the table top of the workbench 1, so as to accurately match the opening and closing device and the stress part of the hanging bracket. A protruding positioning structure can also be arranged on the workbench 1 to cooperate with the hanging bracket, such as Figure 5 A protruding curved plate 8 is arranged at one end of the workbench 1. The structure of the hanging bracket can be deformed to a certain extent, so that the hanging bracket can be buckled on the curved plate 8 to realize the left and right positioning of the hanging bracket on the workbench 1. Under the pushing of the aforementioned driving device, the edge of the material will go up along the curved surface of the curved plate 8, and in this process, the edge of the material will enter the clamping opening of the plate clamp 22.

[0043] The pushing mechanism shown in the figure is a pushing cylinder 12, which is arranged obliquely. The pushing mechanism can also be replaced by a lead screw mechanism, but the preferred pushing mechanism is the pushing cylinder 12. A pushing piece is movably connected to the outer end of the piston rod of the pushing cylinder 12, and moves linearly under the driving of the pushing cylinder 12. An insertion structure is connected to the pushing piece, and moves towards the hanging bracket in the accurate position under the driving of the pushing mechanism. When the plate clamp 22 is acted on, the insertion structure is inserted into the gap between the ear plate 221 and the bracket body 21. Under the action of the pushing cylinder 12, the insertion structure can stably apply force to the plate clamp 22, so that the upper end of the plate clamp 22 deflects outward, and the material flatly placed on the workbench 1 is smoothly guided into the gap between the plate clamp 22 and the bracket body 21 under the driving of the driving device. After the piston rod in the pushing cylinder 12 retracts, the clamping of the material is completed.

[0044] The pushing member comprises a movable frame 18, which comprises two parallel side plates 182, and two limiting rods 181 bridging the two side plates 182 and arranged in parallel and at intervals. A guide wheel 16 is coupled to the front end of the pushing cylinder 12 through a coupling frame, and the guide wheel 16 corresponds to the position of one of the side plates 182. When the piston rod in the pushing cylinder 12 retracts, the side plate 182 touches the outer circumferential surface of the guide wheel 16, so that the movable frame 18 is stabilized at the outer end of the piston rod. A fixed block 19 is fixed to the outer end of the piston rod in the pushing cylinder 12, and the fixed block 19 is located in the interval between the two limiting rods 181. The movable frame 18 is pivoted to the fixed block 19. A torsion spring is arranged at the pivoted position of the movable frame 18, and acts on the movable frame 18, so that the movable frame 18 has a certain stability on the fixed block 19. The insertion structure is arranged on the movable frame 18, and the insertion structure is an insertion rod 20, which is movably bridged to the movable frame 18. The pushing member of this structure can be stably wrapped on the lug plate 221 of the plate clamp 22 when acting on the plate clamp 22, so as to stably apply force to the plate clamp 22. The insertion rod 20 is L-shaped, and a fixed sleeve 202 is fixed to one side of the movable frame 18. One end of the insertion rod 20 is inserted into the fixed sleeve 202 at an interval. A spring 201 is sleeved on the insertion rod 20 and acts on the insertion rod 20, and the spring 201 urges the other end of the insertion rod 20 to abut against the corresponding side plate 182 of the movable frame 18. A notch is arranged on the corresponding side plate 182, and the other end of the insertion rod 20 is used to abut into the notch, so as to realize accurate positioning of the insertion rod 20 on the movable frame 18, so that the insertion rod 20 can be accurately positioned when acting on the plate clamp 22.

[0045] A slide rail 14 is arranged on the lower side of the pushing cylinder 12, and the slide rail 14 is arranged along the length direction of the pushing cylinder 12. A sliding block 15 is movably arranged on the slide rail 14. One end of the coupling piece 17 is fixed to the sliding block 15, and the other end is fixed to the fixed block 19. The movement direction of the movable frame 18 is defined by the slide rail 14 and the piston rod in the pushing cylinder 12, so that the movable frame 18 can accurately move in a straight line, and the movable frame 18 can accurately cooperate with the lug plate 221 of the plate clamp 22.
