Description

Technical Field

[0001] The invention relates to the technical field of pallet production and processing, and in particular to a directional conveying and turning structure for automated pallet production. Background Art

[0002] A pallet is a horizontal platform device used for mechanical handling, storage and transportation of goods. It is usually designed to be suitable for operation by mechanical equipment such as forklifts, stackers, conveyor belts, etc., and can carry a certain weight of goods. Depending on the material, structure and usage scenario, pallets are divided into various types such as wooden pallets, plastic pallets and metal pallets.

[0003] Plastic pallets are suitable for a variety of industries due to their durability, hygiene and lightness. Depending on the usage scenarios, plastic pallets are usually of two types: single-sided and double-sided. Double-sided plastic pallets consist of two symmetrical trays and multiple supporting legs fixedly connected between the two trays (usually distributed in a nine-leg or river-shaped pattern). They are generally formed in one piece using blow molding or injection molding.

[0004] In the process of producing double-sided plastic pallets through injection molding, plastic protrusions generally appear near the gate and vent holes of the mold. After the double-sided plastic pallet is formed and demolded, these protrusions need to be removed by manual or automatic trimming equipment. The current removal method is to first clean the protrusions on one of the disks of the double-sided plastic pallet through automated equipment, then turn it over manually or by a robotic arm, and then clean the protrusions on the other disk. During the turning process, the position of the double-sided plastic pallet may move. Since the position of the protrusions on the double-sided plastic pallet is generally relatively fixed during normal production, the automated equipment needs to reposition it before cleaning the other side. On the one hand, this will consume additional manpower and material resources, resulting in an increase in processing costs, and on the other hand, it will also reduce production and processing efficiency. Summary of the invention

[0005] Technical issues solved

[0006] In view of the above-mentioned shortcomings of the prior art, the present invention provides a directional conveying and turning-over structure for the automated production of pallets, which can effectively solve the problem in the prior art that when trimming the protrusions on the two surfaces of a double-sided plastic pallet, the turning-over action needs to be completed manually or by separate automated equipment, and the pallet needs to be repositioned after turning over, which will lead to an increase in working steps, an increase in processing costs and a decrease in production and processing efficiency.

[0007] Technical Solution

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] The present invention provides a directional conveying and turning structure for automated production of pallets, comprising:

[0010] The clamping mechanism includes two pillars, which are symmetrically fixed on the left and right. The upper ends of the pillars are connected with push rods that slide left and right.

The clamp is fixedly connected to the shell by a pressure spring. The adjacent end surfaces of the two left-right symmetrical clamps are both chamfered. The ends of the two connecting rods away from the longitudinal section of the U-shaped plate are hinged with a push plate through a hinge plate. A counterweight is fixedly connected to the upper end surface of the upper shell.

[0015] Furthermore, the linkage assembly includes a No. 1 transmission gear, which is slidably sleeved on the push rod and located between the support bracket and the pillar. A No. 2 transmission gear is meshed above the No. 1 transmission gear. The No. 2 transmission gear is rotatably connected to the pillar through an axle rod, and the size of the No. 2 transmission gear is larger than that of the No. 1 transmission gear. A protective shell is commonly provided on the outer sides of the No. 1 transmission gear and the No. 2 transmission gear, and the protective shell is fixedly connected to the pillar.

[0016] Furthermore, the trimming mechanism includes a slide rail, two of which are symmetrically arranged front and back through a bracket, and electric sliders are arranged on the two slide rails for sliding left and right, and a mounting rod is fixedly connected between the two electric sliders, and a connecting piece is fixedly sleeved in the middle of the mounting rod, and stabilizing components for keeping the pallet level are symmetrically connected on the front and rear sides of the cylindrical cam on the mounting rod, and a plurality of cutting components for trimming burrs on the surface of the pallet are also connected front and back to the mounting rod.

[0017] Furthermore, the stabilizing assembly includes a pressure rod, a pressure rod is rotatably sleeved on the mounting rod, a roller is rotatably connected to the lower end of the pressure rod, and an annular plate is fixedly sleeved on the mounting rod, and the annular plate is connected to the pressure rod via a torsion spring.

[0018] Furthermore, the cutting assembly includes a vertical rod, the upper end of the vertical rod is fixedly connected to a rod sleeve, the rod sleeve is slidably connected to the mounting rod, an arc plate is fixedly connected to the rod sleeve, a circular hole is opened on the arc plate, and threaded holes matching the circular holes are evenly opened on the front and back side walls of the mounting rod, the arc plate is fixedly connected to the mounting rod by external bolts arranged in the corresponding circular holes and threaded holes, the side walls of the vertical rod are connected to a cutting blade for cutting the protrusions on the surface of the tray through a trigger module, and cutting edges are arranged on both left and right ends of the cutting blade.

[0019] Furthermore, the connecting rod is fixedly connected to the side wall of the vertical rod and points to the right, and two groups of scissor plate groups are connected to the connecting rod with a front-to-back symmetrical rotation through an axial rod, and both ends of the corresponding scissor plates on the two groups of scissor plate groups are fixedly connected through a round rod, and a connecting seat is rotatably connected to the round rod, and two connecting seats located at the same height are commonly connected with a connecting plate, and the two connecting seats on the upper left and lower right are slidingly connected to the upper and lower connecting plates respectively, and the two connecting seats on the upper right and lower left are fixedly connected to the upper and lower connecting plates respectively, and the left and right ends of the upper connecting plate are fixedly connected with L-shaped trigger plates, and the vertical section of the left L-shaped trigger plate is provided with a makeshift groove that matches the connecting rod on the left and right sides, and the lower end surface of the lower connecting plate is fixedly connected to the cutting blade through a connecting strip, and the connecting rod is symmetrically connected with limiting columns that match the scissor plate group on the front-to-back symmetrical connection.

[0020] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: the present invention is provided with a clamping mechanism, in which the push rod and the clamping assembly cooperate with each other to clamp the double-sided plastic pallet on the support frame, and adjust the position of the double-sided plastic pallet while clamping it, so as to facilitate the subsequent turning over and trimming of the double-sided plastic pallet. The present invention is also provided with a flipping mechanism, in which the ball spring in the flipping mechanism can limit the rotation of the cylindrical cam when it is located in the guide groove, so that the support frame remains stable before flipping. In the process of the ball spring moving rightward with the connecting piece, the protrusions on the disk surface of the double-sided plastic pallet will be cleaned by the trimming mechanism, and the cutting blade in the trimming mechanism will move down to contact the double-sided plastic pallet when and only when encountering the protrusions under the action of the trigger module to clean the protrusions. In this way, scratches are avoided due to contact with the surface of the double-sided plastic pallet during movement. When the ball spring enters the guide groove on the right cylindrical cam and slides along the guide groove on the right cylindrical cam, it will drive the right cylindrical cam to rotate, thereby driving the clamping mechanism and the double-sided plastic pallet to rotate synchronously through the linkage assembly, so as to achieve the flipping of the double-sided plastic pallet. After flipping, the ball spring moves to the left and resets under the drive of the mounting rod, and the protrusions on the other surface of the double-sided plastic pallet are cleaned through the trimming mechanism. Compared with traditional cleaning methods, this cleaning method is more efficient and can effectively reduce manpower and material costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] The present invention will be further described below in conjunction with the embodiments.

[0032] Example:

[0033] See also Figure 1 - Figure 7The present invention provides a technical solution: a directional conveying and turning structure for automated production of pallets, comprising a clamping mechanism 1, wherein the clamping mechanism 1 comprises a pillar 11, wherein two pillars 11 are symmetrically and fixedly arranged on the left and right sides, wherein the upper ends of the pillars 11 are slidably connected to push rods 12, wherein the side walls of the push rods 12 are fixedly connected to limit strips extending in the left and right directions, wherein the ends of the two push rods 12 that are close to each other are symmetrically connected to clamping assemblies 13, and the ends of the two push rods 12 that are far away from each other are both rotatably connected to an external cylinder piston rod, and the push rods 12 are connected to a turning mechanism 2 that drives them to rotate.

[0034] The clamping assembly 13 includes a support frame 131, which is fixedly mounted on the end of the push rod 12 away from the pillar 11. The support frame 131 is composed of a connecting frame and a plurality of L-shaped frames 132 evenly and fixedly connected to the lower end surface of the connecting frame, and the lower end surface height of the connecting frame is higher than the lower end surface height of the tray. The end of the push rod 12 away from the pillar 11 is also fixedly connected to a U-shaped plate 133, and a positioning module 134 is commonly connected between the two transverse sections of the U-shaped plate 133.

[0035] The positioning module 134 includes a mounting member 1341, which is composed of two front-to-back symmetrical shells and a connecting rod fixedly connected between the two shells. There are two mounting members 1341 that are symmetrical and slidably connected between the two transverse sections of the U-shaped plate 133. An opening is provided at the end of the shell away from the longitudinal section of the U-shaped plate 133, and a clamping claw 1342 is slidably connected to the shell front and back through a cross bar. The clamping claw 1342 is fixedly connected to the shell through a pressure spring 1343. Under the action of the pressure spring 1343, the two corresponding clamping claws 1342 are close to each other in a natural state, and the end surfaces of the two left-right symmetrical clamping claws 1342 that are close to each other are both chamfered to facilitate the corresponding clamping claws 1342 to clamp the supporting feet of the double-sided plastic pallet. The ends of the two connecting rods away from the longitudinal section of the U-shaped plate 133 are hinged with a push plate 1344 through a hinge plate, and a counterweight block 1345 is fixedly connected to the upper end surface of the upper shell, so that the two mounting members 1341 are close to each other in a natural state.

[0036] During specific operation, in the initial state, the flipping mechanism 2 and the trimming mechanism 3 cooperate with each other to keep the push rod 12 stable in a natural state. At this time, the horizontal sections of the three L-shaped frames 132 are all in a horizontal state, and the demoulding double-sided plastic pallet is moved to the L-shaped frame 132 by an external mechanical arm, and then the two external cylinders are started at the same time, and the left and right push rods 12 are pushed in the same direction by their piston rods, thereby pushing the clamping claws 1342 to move toward the position of the double-sided plastic pallet. When the chamfered surface on the clamping claw 1342 contacts the supporting feet of the double-sided plastic pallet (located at both ends of the nine-legged plastic pallet and close to the middle supporting feet) and continues to feed, the pressure spring 1343 is further compressed, and the two clamping claws 1342 on the same mounting part 1341 move away synchronously, and the position of the double-sided plastic pallet in the front and rear directions is adjusted while clamping the supporting feet.

[0037] Then the two symmetrical push rods 12 continue to feed in the same direction, driving the push plate 1344 to contact the supporting feet, thereby driving the angle between the two hinged plates to increase, and then driving the two corresponding upper and lower mounting parts 1341 to move away synchronously. During this process, the two corresponding upper and lower clamping claws 1342 also move away synchronously, while clamping the double-sided plastic pallet in an inner support manner, the position of the double-sided plastic pallet in the up and down directions is adjusted, and at the same time, the clamping and position adjustment effects are achieved, so as to facilitate the subsequent flipping and cleaning of the protrusions on the upper and lower disk surfaces.

[0038] The flip mechanism 2 includes a cylindrical cam 21, which is rotatably connected to the pillar 11 through an axle rod. A guide groove 22 is provided on the surface of the cylindrical cam 21. The guide groove 22 includes two horizontal sections of different lengths and parallel to the axis of the cylindrical cam 21 and an inclined section connected between the two horizontal sections. The end of the horizontal section away from the pillar 11 is open, and the longer horizontal section on the left cylindrical cam 21 is aligned with the shorter horizontal section on the right cylindrical cam 21. The axle rod and the push rod 12 are connected through a linkage assembly 23. A ball spring 24 is slidably provided in the guide groove 22. The ball spring 24 is connected to the trimming mechanism 3 through a connecting piece. The depth of the longer horizontal section of the guide groove 22 is less than the depth of the shorter horizontal section and the inclined section to ensure that the ball spring 24 always slides out along the longer horizontal section.

[0039] The linkage assembly 23 includes a No. 1 transmission gear 231, which is slidably mounted on the push rod 12 and located between the support bracket 131 and the pillar 11. A No. 2 transmission gear 232 is meshed above the No. 1 transmission gear 231. The No. 2 transmission gear 232 is rotatably connected to the pillar 11 through an axle rod, and the size of the No. 2 transmission gear 232 is larger than the No. 1 transmission gear 231. A protective shell 233 is commonly provided on the outer sides of the No. 1 transmission gear 231 and the No. 2 transmission gear 232, and the protective shell 233 is fixedly connected to the pillar 11.

[0040] The trimming mechanism 3 includes a slide rail 31, two of which are symmetrically arranged front and back through a bracket, and electric sliders are arranged on the two slide rails 31 for sliding left and right. In the initial state, the two electric sliders are located at the leftmost end of the slide rail 31, and the ball spring 24 is located in the longer horizontal section of the left guide groove 22 to limit the cylindrical cam 21 to prevent it from rotating. A mounting rod 32 is fixedly connected between the two electric sliders, and a connecting piece is fixedly sleeved in the middle of the mounting rod 32. Stabilizing components 33 for keeping the pallet horizontal are symmetrically connected on the front and rear sides of the cylindrical cam 21 on the mounting rod 32, and a plurality of cutting components 34 for trimming burrs on the surface of the pallet are also connected front and back to the mounting rod 32.

[0041] The stabilizing assembly 33 includes a pressure rod 331 rotatably sleeved on the mounting rod 32 , the lower end of the pressure rod 331 is rotatably connected to a roller 332 , and an annular plate 333 is fixedly sleeved on the mounting rod 32 , and the annular plate 333 is connected to the pressure rod 331 via a torsion spring 334 .

[0042] The cutting assembly 34 includes a vertical rod 341, and a rod sleeve 342 is fixedly connected to the upper end of the vertical rod 341. The rod sleeve 342 is slidably connected to the mounting rod 32, and an arc plate 343 is fixedly connected to the rod sleeve 342. A circular hole is opened on the arc plate 343, and threaded holes matching the circular holes are evenly opened on the front and rear side walls of the mounting rod 32. The arc plate 343 is fixedly connected to the mounting rod 32 by external bolts arranged in the corresponding circular holes and threaded holes. This installation method makes the position of each rod sleeve 342 on the mounting rod 32 adjustable. However, since the double-sided plastic pallet molds of different sizes are also different, the position of the surface protrusions may also change. At this time, adjusting the relative position of each rod sleeve 342 on the mounting rod 32 can adapt to this change, thereby improving the application scope of the cutting assembly 34. The side wall of the vertical rod 341 is connected to a cutting blade 345 for cutting the protrusions on the surface of the pallet through a trigger module 344, and the cutting blade 345 is provided with cutting edges at both ends.

[0043] The trigger module 344 includes a connecting rod 3441, which is fixedly connected to the side wall of the vertical rod 341 and points to the right. The connecting rod 3441 is connected to two sets of scissor plate groups 3442 by a shaft rod, and the two ends of the corresponding scissor plates on the two sets of scissor plate groups 3442 are fixedly connected by a round rod. The round rod is rotatably connected to a connecting seat 3443, and the two connecting seats 3443 at the same height are connected to a connecting plate. The two connecting seats 3443 on the upper left and lower right are connected to the upper and lower two The connecting plates are slidingly connected to each other, and the two connecting seats 3443 on the upper right and lower left are fixedly connected to the upper and lower connecting plates respectively. The left and right ends of the upper connecting plate are fixedly connected with L-shaped trigger plates 3444, and the vertical section of the left L-shaped trigger plate 3444 is provided with a clearance groove that matches the connecting rod 3441 on the left and right. The lower end surface of the lower connecting plate is fixedly connected to the cutting blade 345 through a connecting strip, and the connecting rod 3441 is symmetrically connected to the front and back with limiting columns 3445 that match the scissor plate group 3442.

[0044] During specific operation, after the double-sided plastic pallet is fixedly clamped by the clamping claws 1342, the two electric sliders slide to the right synchronously, and the connecting piece and the ball spring 24 are driven to slide to the right synchronously through the mounting rod 32. Before the ball spring 24 disengages from the guide groove 22 on the left cylindrical cam 21 but reaches the top of the double-sided plastic pallet, the plastic pallet may be slightly deflected due to its own uneven mass distribution (generally due to process reasons or because it is designed as an incompletely symmetrical structure).

[0045] After the ball spring 24 continues to move to the right to the top of the double-sided plastic pallet, the two pressure rods 331 also contact the left end surface of the double-sided plastic pallet and automatically deflect to the left while continuing to move to the right until the two rollers 332 move to the upper disk surface of the double-sided plastic pallet. At this time, the two pressure rods 331, under the action of the torsion spring 334, synchronously apply downward pressure to the double-sided plastic pallet from the front and rear sides through the rollers 332, thereby restoring the double-sided plastic pallet to a stable state again.

[0046] Afterwards, as the mounting rod 32 continues to move to the right, the cutting assembly 34 is driven to move to the right synchronously. When no protrusion is encountered, under the action of the gravity of the L-shaped trigger plate 3444 itself, the left-right angle between the two scissor plates in the same scissor plate group 3442 is relatively small, and the relative position of the cutting blade 345 is relatively high. Therefore, during the movement process, it is always located above the double-sided plastic pallet and will not contact the upper disk surface thereof, thereby avoiding scratches on its outer surface. When encountering a protrusion on the upper disk surface of the double-sided plastic pallet, the L-shaped trigger plate 3444 cannot continue to move forward due to the restriction of the protrusion. The scissor plate group 3442 is reset again due to the gravity of the L-shaped trigger plate 3444, and the cutting blade 345 moves up again to disengage from the double-sided plastic pallet.

[0047] When the ball spring 24 continues to move to the right and is out of the double-sided plastic tray, the roller 332 is still pressed on the upper disk surface of the double-sided plastic tray to keep it horizontal. When the ball spring 24 moves to the shorter horizontal section of the guide groove 22 of the right cylindrical cam 21, the roller 332 is separated from the upper disk surface of the double-sided plastic tray, and the pressure rod 331 is reset under the action of the torsion spring 334, and then the ball spring 24 continues to move to the right and enters the inclined section of the guide groove 22 of the right cylindrical cam 21, driving the right cylindrical cam 21 to rotate. The rotation of the right cylindrical cam 21 drives the right No. 2 transmission gear 232 to rotate through the shaft, thereby driving the right No. 2 transmission gear 232 to rotate. The right side transmission gear No. 1 231 rotates, and at the same time, since the size of the right side transmission gear No. 2 232 is larger than the right side transmission gear No. 1 231, in this process, due to the increase in the transmission ratio between the gears, the clamping mechanism 1 and the double-sided plastic pallet can be synchronously flipped 180 degrees when the right side transmission gear No. 2 232 and the right side cylindrical cam 21 rotate at a small angle, and finally the double-sided plastic pallet is automatically flipped. In this process, the left cylindrical cam 21 is driven by the clamping mechanism 1, the left side transmission gear No. 1 231 and the left side transmission gear No. 2 232 to rotate a certain angle until the shorter horizontal section of the guide groove 22 is at the top and the rotation stops.

[0048] After the double-sided plastic pallet is flipped, its lower disk surface moves upward. At this time, the two electric sliders drive the mounting rod 32 to move left and reset, and then the protrusions on the lower disk surface of the double-sided plastic pallet are cleaned by the left edge of the cutting blade 345 in the same trimming method as the above-mentioned trimming method. When the cleaning is completed, the ball spring 24 moves left to the short horizontal section on the guide groove 22 on the left cylindrical cam 21 and stops. At this time, the two push rods 12 move away synchronously, driving the clamping mechanism 1 to release the clamping of the double-sided plastic pallet, and the double-sided plastic pallet falls freely to the external conveyor belt below. Then, the electric slider drives the mounting rod 32, the connecting piece and the ball spring 24 to continue to slide along the short horizontal section of the guide groove 22 to the inclined section, and finally slide to the long horizontal section, so as to achieve the reset of the left cylindrical cam 21. During the reset process of the left cylindrical cam 21, the clamping mechanism 1 is also reset to the initial stage to facilitate the processing of the next double-sided plastic pallet.
