Description

Technical Field

[0001] The utility model relates to the technical field of mechanical automation, in particular to an upper plate machine with semi-automatic feeding. Background Art

[0002] Traditional pipeline feeding requires manual on-site supervision, which increases the manufacturing cost of enterprises and is not conducive to the automated layout to improve the overall production efficiency.

[0003] In view of this, a feeding mechanism for an automated feeder disclosed in the Chinese patent document with the authorization number CN212558352U includes a stacking mechanism and a conveyor belt. The stacking mechanism includes two sets of transmission chain assemblies symmetrically arranged left and right. Each set of transmission chain assemblies includes two vertically symmetrically arranged driving chains. Both ends of each driving chain are respectively sleeved with driving sprockets, and the driving sprockets of the two driving chains are sleeved on the same synchronous transmission shaft. A plurality of groups of L-shaped resting strips are arranged in parallel between the two driving chains of the same set of transmission chain assemblies. The two ends of the vertical plates constituting the L-shaped resting strips are respectively fixed on the two driving chains of the same set of transmission chain assemblies. The material tray is horizontally placed on the horizontal plates of the L-shaped resting strips of the two sets of transmission chain assemblies. The conveyor belt is located between the two sets of transmission chain assemblies and is in contact with the material tray that has dropped to the bottom. The conveyor belt is horizontally installed on the conveying support, and a detector is installed on the conveying support. When the detector senses that the material tray has dropped to the conveyor belt, the driving chain is stopped, and the conveyor belt is started to horizontally move out the material tray; however, the distance between the two sets of transmission chain assemblies is fixed and non-adjustable, so the material tray cannot be replaced according to the material size, resulting in a relatively high production cost.

[0004] Therefore, it is necessary to improve the deficiencies of the above prior art. Summary of the Invention

[0005] The technical problem to be solved by the utility model is to provide an upper plate machine with semi-automatic feeding in view of the deficiencies of the above prior art, and solve the problem that the distance between the two sets of transmission chain assemblies in the prior art cannot be adjusted, resulting in a relatively high production cost.

[0006] To achieve the above object, the utility model provides the following technical solutions: An upper plate machine with semi-automatic feeding includes a frame, a first transmission chain assembly, a second transmission chain assembly, and a discharging mechanism arranged between the first transmission chain assembly and the second transmission chain assembly. The first transmission chain assembly and the second transmission chain assembly are vertically and parallelly installed on the frame, and a distance adjusting mechanism capable of causing the first transmission chain assembly to translate closer to or farther from the second transmission chain assembly is arranged between the first transmission chain assembly and the frame.

[0007] With the above technical solution, when it is necessary to adjust the distance between the first transmission chain assembly and the second transmission chain assembly, the distance between the first transmission chain assembly and the second transmission chain assembly can be changed by adjusting the distance adjusting mechanism to make the first transmission chain assembly translate closer to or farther away from the second transmission chain assembly, so as to adapt to materials of different sizes and greatly reduce the production cost.

[0008] The further setting of the above technical solution is that: the distance adjusting mechanism includes a distance adjusting screw rod rotatably connected to the frame and a distance adjusting motor installed on the frame. The distance adjusting screw rod is in screw drive connection with the first transmission chain assembly. The axial direction of the distance adjusting screw rod is perpendicular to the parallel plane of the first transmission chain assembly and the second transmission chain assembly. The rotating shaft of the distance adjusting motor is linked with one end of the distance adjusting screw rod so that the distance adjusting screw rod can rotate axially.

[0009] With the above technical solution, when adjusting the distance, start the distance adjusting motor to drive the forward and reverse rotation of the distance adjusting screw rod. The screw drive of the distance adjusting screw rod makes the first transmission chain assembly translate closer to or farther away from the second transmission chain assembly along the axial direction of the distance adjusting screw rod, so as to change the distance between the first transmission chain assembly and the second transmission chain assembly.

[0010] The further setting of the above technical solution is that: four distance adjusting screw rods are provided and distributed at the corresponding four corners of the first transmission chain assembly. The same side of the four distance adjusting screw rods is in chain drive connection with the rotating shaft of the distance adjusting motor.

[0011] With the above technical solution, by arranging four distance adjusting screw rods at the corresponding four corners of the first transmission chain assembly, and the distance adjusting motor drives the four distance adjusting screw rods to rotate synchronously through chain drive, the translation process of the first transmission chain assembly in screw drive is more stable and smooth.

[0012] The further setting of the above technical solution is that: the discharging mechanism includes detection mechanisms respectively arranged at the lower ends of the opposite sides of the first transmission chain assembly and the second transmission chain assembly, and a material pushing mechanism located between the two detection mechanisms.

[0013] With the above technical solution, when the two ends of the material are respectively lowered to the detection mechanisms by the first transmission chain assembly and the second transmission chain assembly, the trigger signal makes the control system stop lowering the material by the first transmission chain assembly or the second transmission chain assembly. After both ends of the material stop lowering, the material is then pushed out to the equipment of the next process from the middle of one end of the material by the material pushing mechanism; since the two sides of the first transmission chain assembly and the second transmission chain assembly are respectively detected and controlled, the effect of automatic deviation correction can be achieved.

[0014] The further setting of the above technical solution is: The detection mechanism includes a detection bracket, an arcuate lever, and a position sensor installed at the lower end of the first transmission chain assembly or the second transmission chain assembly. A lever fulcrum for rotatably connecting the middle part of the arcuate lever is provided on the detection bracket. The position sensor is installed at the upturned end of the detection bracket away from the arcuate lever. An L-shaped groove capable of abutting against the bottom and side surfaces of the material is provided on one side of the detection bracket close to the pushing mechanism. The upturned end of the arcuate lever is higher than the bottom surface of the L-shaped groove.

[0015] With the above technical solution, when one end of the material is placed on the L-shaped groove, the bottom of the material abuts against the upturned end of the arcuate lever and presses it down. The other end of the arcuate lever is upturned, and the position sensor detects the position change of the arcuate lever and triggers a signal to the control system, thereby realizing the in-place detection function of one end of the material.

[0016] The further setting of the above technical solution is: The pushing mechanism includes a pushing bracket, a driving sprocket, a plurality of driven sprockets rotatably connected to the pushing bracket, a pushing chain, and a pushing driving mechanism for driving the driving sprocket to rotate. The driving sprocket and the driven sprockets are chain-driven by the pushing chain. Pushing stoppers are provided on the pushing chain. A zero return sensor is further provided at one end of the pushing bracket.

[0017] With the above technical solution, when it is necessary to push out the material, the pushing driving mechanism drives the driving sprocket to rotate, causing the pushing chain to rotate and driving the pushing stoppers to move and abut against the side surface of the material and push the material to slide to the equipment at the next process; when the pushing stoppers pass by the zero return sensor, they can be detected, enabling the control system to control the stop timing of the pushing driving mechanism so that the pushing stoppers can return to the initial position.

[0018] The further setting of the above technical solution is: The pushing driving mechanism includes a square shaft rotatably connected to the machine frame and a pushing motor for driving the square shaft to rotate. The rotating shaft of the pushing motor is chain-driven with one end of the square shaft. The square shaft is circumferentially fixed to the driving sprocket.

[0019] With the above technical solution, after the pushing motor is started, it drives the square shaft to rotate, and the square shaft drives the driving sprocket to rotate, thereby driving the pushing mechanism to perform the pushing operation.

[0020] The further setting of the above technical solution is: Two pushing stoppers are provided and evenly distributed on the pushing chain.

[0021] With the above technical solution, by providing two pushing stoppers, the pushing chain only needs to rotate half a turn to complete a pushing operation, thereby greatly improving the efficiency.

[0022] The further setting of the above technical solution is as follows: both the first transmission chain assembly and the second transmission chain assembly include a transmission bracket and two vertically symmetrically arranged drive chains. Transmission sprockets are sleeved at both ends of each drive chain, and the transmission sprockets of the two drive chains are sleeved with a synchronous drive shaft rotatably connected to the transmission bracket. One end of the synchronous drive shaft is chain-driven by a transmission drive motor. A plurality of E-shaped shelving frames are arranged in parallel between the two drive chains, and both ends of the E-shaped shelving frames are respectively fixed to the two drive chains.

[0023] With the above technical solution, after manually placing the materials row by row on the two horizontally opposite E-shaped shelving frames of the first transmission chain assembly and the second transmission chain assembly, start the transmission drive motor to drive the synchronous drive shaft to rotate, and then drive the drive chains to rotate. The drive chains drive the E-shaped shelving frames to be transmitted downward to the discharging mechanism and then stop moving. When the materials are pushed out, repeat the above operation to make the next material continue to be transmitted to the discharging mechanism and then stop moving. Repeat this cycle until all the materials are sent out.

[0024] The further setting of the above technical solution is as follows: a speed measurement code disc is installed at one end of the synchronous drive shaft, and a matching speed measurement sensor is arranged beside the speed measurement code disc.

[0025] With the above technical solution, through the cooperation of the speed measurement code disc on the synchronous drive shaft and the speed measurement sensor, the distance of the rotation of the drive chain can be monitored, so that the maximum descending distance can be preset through the control system, the number of materials fed at one time can be further set, and the work will automatically stop after the number is completed, avoiding the idling of the machine.

[0026] The beneficial effects achieved by the present utility model are as follows: the distance between the two transmission chain assemblies can be adjusted, so that materials of different sizes can be adapted, and the production cost is greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] As Figure 1-2 shown, a semi-automatic feeding upper plate machine includes a frame 1, a first transmission chain assembly 2, a second transmission chain assembly 3, and a discharging mechanism 4 disposed between the first transmission chain assembly 2 and the second transmission chain assembly 3. The first transmission chain assembly 2 and the second transmission chain assembly 3 are vertically and parallelly installed on the frame 1. A distance adjustment mechanism 5 capable of causing the first transmission chain assembly 2 to translate closer to or farther from the second transmission chain assembly 3 is provided between the first transmission chain assembly 2 and the frame 1. The distance adjustment mechanism 5 includes a distance adjustment screw rod 51 rotatably connected to the frame 1 and a distance adjustment motor 52 installed on the frame. The distance adjustment screw rod 51 is in screw transmission connection with the first transmission chain assembly 2. The axial direction of the distance adjustment screw rod 51 is perpendicular to the parallel plane of the first transmission chain assembly 2 and the second transmission chain assembly 3. The rotating shaft of the distance adjustment motor 52 is linked with one end of the distance adjustment screw rod 51 so that the distance adjustment screw rod 51 can rotate axially. The distance adjustment screw rod 51 is provided with four and is distributed at the corresponding four corners of the first transmission chain assembly 2. The same side of the four distance adjustment screw rods 51 and the rotating shaft of the distance adjustment motor 52 are in chain transmission; when adjusting the distance, the distance adjustment motor 52 is started to drive the four distance adjustment screw rods 51 to rotate synchronously. The distance adjustment screw rod 51 is in screw transmission to make the first transmission chain assembly 2 translate closer to or farther from the second transmission chain assembly 3, thereby realizing the adjustment of the distance between the first transmission chain assembly 2 and the second transmission chain assembly 3 as needed.

[0038] As Figure 1 、 3 、4, 5, 6 shown, the discharging mechanism 4 includes detection mechanisms 41 respectively provided at the lower ends of the opposite sides of the first transmission chain assembly 2 and the second transmission chain assembly 3, and a pusher mechanism 42 located between the two detection mechanisms 41.

[0039] The detection mechanism 41 includes a detection support 410, an arcuate lever 411, and a position-in-place sensor 412 installed at the lower end of the first transmission chain assembly 2 or the second transmission chain assembly 3. A lever fulcrum 413 for rotatably connecting the middle part of the arcuate lever 411 is provided on the detection support 410. The position-in-place sensor 412 is installed at the upturned end of the detection support 410 away from the arcuate lever 411. An L-shaped groove 414 capable of abutting against the bottom and side surfaces of the material is provided on one side of the detection support 410 close to the material pushing mechanism 42. The upturned end of the arcuate lever 411 is higher than the bottom surface 414 of the L-shaped groove. When one end of the material is transported onto the L-shaped groove 414, the bottom surface of the material presses down the upturned end of the arcuate lever 411, and the other end of the arcuate lever 411 upturns. The position-in-place sensor 412 detects the position change and triggers a signal to the control system.

[0040] The material pushing mechanism 42 includes a material pushing support 420, a driving sprocket 421, a plurality of driven sprockets 422 rotatably connected to the material pushing support 420, a material pushing chain 423, and a material pushing driving mechanism for driving the driving sprocket 421 to rotate. The driving sprocket 421 and the driven sprockets 422 are chain-driven by the material pushing chain 423. A material pushing stop 424 is provided on the material pushing chain 423. A zero return sensor 425 is further provided at one end of the material pushing support 420. The material pushing driving mechanism includes a square shaft 426 rotatably connected to the machine frame 1 and a material pushing motor 427 for driving the square shaft 426 to rotate. The rotating shaft of the material pushing motor 427 is chain-driven with one end of the square shaft 426. The square shaft 426 is circumferentially fixed to the driving sprocket 421. Two material pushing stops 427 are provided and evenly distributed on the material pushing chain 423. When pushing the material, the rotating shaft of the material pushing motor 427 drives the square shaft 426 to rotate, the square shaft 426 drives the driving sprocket 421 to rotate, and then drives the material pushing chain 423 to rotate. The material pushing chain 423 drives the material pushing stop 424 thereon to move and abut against the side surface of the material and push the material to the equipment at the next process. The zero return sensor 425 detects the passing material pushing stop 424, so as to facilitate the control system to control the closing timing of the material pushing motor 427, so that the material pushing stop 424 can be located at the initial material pushing position before the material pushing starts.

[0041] As Figures 7-9As shown in the figure, both the first transmission chain assembly 2 and the second transmission chain assembly 3 include a transmission support 20 and two vertically symmetrically arranged transmission chains 21. Transmission sprockets 22 are sleeved at both ends of each transmission chain 21. Synchronous transmission shafts 23 rotatably connected to the transmission support 20 are sleeved with the transmission sprockets 22 of the two transmission chains 21. A transmission drive motor 24 is chain-driven at one end of the synchronous transmission shaft 23. Multiple groups of E-shaped shelving frames 25 are arranged in parallel between the two transmission chains 21. Both ends of the E-shaped shelving frame 25 are respectively fixed to the two transmission chains 21; a speed measuring code disc 26 is installed at one end of the synchronous transmission shaft 23, and a matching speed measuring sensor 27 is arranged beside the speed measuring code disc 26; after an operator places the materials row by row on two horizontally opposite groups of E-shaped shelving frames 25 of the first transmission chain assembly 2 and the second transmission chain assembly 3, the transmission drive motor 24 is started to drive the synchronous transmission shaft 23 to rotate, thereby driving the transmission chain 21 to rotate. The transmission chain drives the E-shaped shelving frame 25 to be transmitted downward to the discharging mechanism 4 and then stops moving; through the cooperation of the speed measuring code disc 26 and the speed measuring sensor 27 on the synchronous transmission shaft 23, the rotation distance of the transmission chain 21 can be monitored, so that the maximum descending distance can be preset through the control system, and the number of materials fed at one time can be further set. After the number is completed, the machine automatically stops working to avoid idling of the machine.

[0042] In the technical solution of this application, when it is necessary to adjust the distance between the first transmission chain assembly 2 and the second transmission chain assembly 3, the distance between the first transmission chain assembly 2 and the second transmission chain assembly 3 is changed by adjusting the distance adjusting mechanism 5 to make the first transmission chain assembly 2 translate closer to or farther away from the second transmission chain assembly 3, so that materials of different sizes can be adapted, and the production cost is greatly reduced.
