Description

[0001] The invention relates to the field of material transportation, and in particular to a production line and a method for supporting and transporting bulk materials. Background Art

[0002] In the field of automated packaging and conveying, there are a variety of packaging and conveying methods, but they are basically for conveying whole-packaged materials. However, for some materials, such as egg tarts, they need to be conveyed in bulk before packaging.

If the egg tarts are stacked for conveying, the conveying process is likely to cause the stacked egg tarts to spread out.

[0003] Therefore, it is necessary to provide a method for conveying stacked and packaged materials, which can meet the conveying efficiency and ensure the stacking state of the materials. Summary of the invention

[0057] In the description of the present invention, it should be understood that the terms indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.

[0058] The principles and features of the present invention will be described below in conjunction with the drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention. It should be noted that the drawings are all in a very simplified form and use non-precise scales, only for the purpose of conveniently and clearly assisting in explaining the purpose of the embodiments of the present invention.

[0059] As Figure 1 shown, in an embodiment of the present invention, the supporting and conveying production line includes at least one pallet conveying unit and a spacing adjustment and conveying device 700. The pallet conveying unit includes a carrying device 100, a pallet loading device 200, a material loading device and a blanking device. The blanking device includes an inverting device 400 and a clamping and conveying device 500. In this embodiment, there are two pallet conveying units, that is, the carrying device 100, the pallet loading device 200, the material loading device, the inverting device 400 and the clamping and conveying device 500 are respectively provided with two groups;

[0060] The carrying device 100 includes at least one carrying unit, and the carrying unit includes a stacking table 101, a first linear module 102, a second linear module 103 and a pressing device 104. In this embodiment, as Figure 2As shown, there are two carrier units, that is, there are two sets corresponding to the stacking table 101, the first linear module 102, the second linear module 103, and the pressing device 104. The first linear module 102 drives the stacking table 101 and the lifting plate 1012 to move back and forth at the workstations corresponding to the pallet loading device 200, the material loading device, and the unloading device. The second linear module 103 moves in a direction consistent with the moving direction of the first linear module 102 and in the vertical direction. The stacking table 101 and the second linear module 103 are fixedly installed on the moving block of the first linear module 102, as Figure 3 As shown, the stacking table 101 includes a bottom plate 1011 and a lifting plate 1012. The lifting plate 1012 is liftably arranged on the bottom plate 1011. A lifting mechanism 1014 is arranged in driving connection with the lifting plate 1012. At least one positioning hole for limiting the placement of the pallet is arranged on the lifting plate 1012. A foot pad 1013 corresponding to the positioning hole and a lifting hole for the lifting movement of the lifting mechanism 1014 are arranged on the bottom plate 1011. In this embodiment, there are positioning holes for limiting the placement of three lower pallets 3 on one lifting plate 1012. In this embodiment, one pallet can support the same end of two stacks of materials, that is, one pallet has two trays 402. Therefore, six positioning holes are correspondingly arranged on the lifting plate 1012, and a foot pad 1013 is respectively arranged directly below the six positioning holes. The foot pad 1013 is used to increase the support height, and the lifting mechanism 1014 is a cylinder. The pressing device 104 is fixedly installed on the second linear module 103. The pressing device 104 includes a mounting plate 1041 and a pressing block 1042 arranged on the lower side of the mounting plate 1041;

[0061] The pallet loading device 200 is used to convey pallets to the stacking table 101 and support both ends of the materials by means of the pallets. The pallet loading device 200 includes a pallet loading unit corresponding to the carrier unit. Continuing from the above text, as Figure 4 shown, there are two corresponding pallet loading units. Each pallet loading unit includes a lower pallet loading unit 201 and an upper pallet loading unit 202 with different loading heights. Both the lower pallet loading unit 201 and the upper pallet loading unit 202 are respectively provided with at least one pallet loading mechanism 203. Continuing from the above text, in view of the fact that one stacking table 101 can limit the placement of three lower pallets 3, therefore, both a lower pallet loading unit 201 and an upper pallet loading unit 202 are provided with three pallet loading mechanisms 203, as Figure 5As shown in the figure, each pallet loading mechanism 203 includes a pallet rack 2031, a pushing plate, a control mechanism, and a pushing mechanism. The pallet rack 2031 is used for stacking a plurality of (i.e., two or more) pallets. An upper loading port for pallet loading is provided on the bottom frame of the pallet rack 2031. A pushing plate is provided corresponding to the upper loading port, that is, the pushing plate is provided directly below the lower loading port. The pushing plate includes a fixed plate 2032 and a moving plate 2033 movably arranged on the fixed plate 2032 through a slide rail. The pushing mechanism includes a pallet pushing unit 2034 for pushing the pallet and a plate body 402 pushing unit 2035 for pushing the moving plate 2033 (for example, the pallet pushing unit 2034 includes a telescopic electric cylinder and a push plate arranged at the end of the telescopic rod of the telescopic electric cylinder, and the plate body 402 pushing unit 2035 includes a telescopic electric cylinder, and the end of the telescopic rod of the telescopic electric cylinder is fixedly connected to the moving plate 2033). The pushing directions of the pallet pushing unit 2034 and the plate body 402 pushing unit 2035 are the same. The control mechanism includes an elastic sheet 2036 and a suction device. As Figure 6 shown, four elastic sheets 2036 against the lower side of the pallet are provided at the upper loading port of the pallet rack 2031. A passing port corresponding to the upper loading port is provided on the pushing plate, and a suction device capable of applying a suction force to the pallet is provided below the passing port. In this embodiment, the suction device is a vacuum suction cup 2037. The vacuum suction cup 2037 is arranged on a lifting cylinder, and the lifting cylinder drives the vacuum suction cup 2037 to move in the direction of approaching and departing from the pallet, so that the suction force of the vacuum suction cup 2037 can act on the pallet and can support the pallet to move downward;

[0062] The material loading device includes a loading machine and a limiting device for limiting the stacking of materials. The loading machine includes a loading gripper. For example, reference can be made to the patent with the patent application number 202123142768.7 and the name of a telescopic grasping claw. In this embodiment, as Figure 2 , 4 and shown in FIG. 7, the limiting device includes two groups of limiting groups 300 located on both sides of the stacking table 101. Six limiting columns 301 are provided on each group of limiting groups 300. The two groups of limiting groups 300 are arranged on a telescopic driver, and the telescopic driver drives the two groups of limiting groups 300 to move in the direction of approaching or departing from each other. In this embodiment, the telescopic driver is a double-rod double-acting cylinder 302;

[0063] The blanking device clamps and conveys the material with the pallets at both ends. In this embodiment, as Figure 8 shown, the blanking device includes a flipping device 400 corresponding to the carrier device 100 and a clamping and conveying device 500 corresponding to the flipping device 400;

[0064] As Figure 9 and 10As shown, the flipping device 400 includes a mounting arm 401, a disk body 402, a third linear module 403, and a clamping unit. The third linear module 403 is a three-axis linear module. The mounting arm 401 is mounted on the three-axis linear module, and the disk body 402 is rotatably arranged on the mounting arm 401. For example, the mounting arm 401 is rotatably connected to the disk body 402 through a driven shaft. A reduction motor is fixedly mounted on the mounting arm 401. The reduction motor is drivingly connected to a driving shaft. The driving shaft and the driven shaft are connected by a belt drive. The rotational movement of the disk body 402 relative to the mounting arm 401 is controlled by the reduction motor. At least one set of clamping units for clamping the egg tart 1 is arranged on the disk body 402. Continuing from the above, in this embodiment, three sets of clamping units are provided, which are respectively called clamping set one, clamping set two, and clamping set three. At least one set of clamping units includes at least two clamping plates for clamping both ends of the egg tart 1, and at least one of the clamping plates is movable in a direction approaching or departing from the other clamping plate. For the sake of simplicity of description, the two clamping plates in one set of clamping units are respectively an upper clamping plate 404 and a lower clamping plate 405. The upper clamping plate 404 and the lower clamping plate 405 are provided with U-shaped avoidance notches in cooperation with the upper tray 2 and the lower tray 3. In this embodiment, the upper and lower clamping plates in one set of clamping units can move synchronously in a direction approaching or departing from each other. To achieve this synchronous approaching or departing movement, a positive and negative screw method can be adopted. Taking clamping set two as an example, the upper clamping plate 404 and the lower clamping plate 405 are respectively arranged on two positive and negative screws. The two screws are connected by a coupling (or can be directly arranged on a positive and negative thread lead screw). A first bevel gear is fixedly arranged on the screw where the upper clamping plate 404 is located. The first bevel gear meshes with a second bevel gear. The second bevel gear is fixedly arranged on the output shaft of the reduction motor. Thus, under the transmission of the two bevel gears, the rotational movement of the reduction motor can be converted into the linear movement of the upper clamping plate 404 and the lower clamping plate 405 on the screw, so as to facilitate the clamping and releasing actions of one set of clamping plates on the egg tart 1. In view of the fact that both the upper clamping plate 404 and the lower clamping plate 405 can move, accordingly, a window with a certain moving stroke is arranged on the disk body 402 to facilitate the movement of the clamping plates. Clamping set one and clamping set three can be synchronously moved by using the same drive, or can be synchronously moved following clamping set two. In this embodiment, the latter is adopted. More specifically: By fixedly mounting the upper clamping plates 404 in clamping set one and clamping set three on an upper connecting plate, the upper connecting plate is fixedly connected to the upper clamping plate 404 in clamping set two. The upper clamping plate 404 in clamping set two drives the upper clamping plates 404 in clamping set one and clamping set three to move through the upper connecting plate. Similarly, the lower clamping plates 405 in clamping set one and clamping set three are connected to the lower clamping plate 405 in clamping set two through a lower connecting plate;

[0065] As Figure 11As shown, the clamping and conveying device 500 includes a main conveying mechanism 501 and auxiliary conveying mechanisms located on both sides of the main conveying mechanism 501, abutting against the tray and synchronously conveying with the main conveying mechanism 501;

[0066] In this embodiment, both the main conveying mechanism 501 and the auxiliary conveying mechanisms are belt conveying mechanisms. The auxiliary conveying mechanisms are synchronously conveyed with the main conveying mechanism 501 through bevel gear transmission mechanisms. More specifically: as Figure 11 and 12 shown, the reduction motor drives the rotation of the driving shaft. A third bevel gear 504 and a driving wheel are fixedly installed on the driving shaft. A fourth bevel gear 505 is arranged in meshing transmission connection with the third bevel gear 504. The fourth bevel gear 505 is fixedly installed at one end of the conveying rotating shaft of the main conveying mechanism 501. A fifth bevel gear 506 is installed at the other end of the conveying rotating shaft of the main conveying mechanism 501. A driven wheel is arranged in synchronous belt transmission connection with the driving wheel. The driven wheel is fixedly arranged on the conveying rotating shaft of the first auxiliary unit 502. A sixth bevel gear 507 is arranged in meshing transmission connection with the fifth bevel gear 506. The sixth bevel gear 507 is fixedly installed on the driven shaft. The driven shaft and the conveying rotating shaft of the second auxiliary unit 503 are connected by synchronous belt transmission. Thus, the synchronous driving of the three conveying units is realized by one reduction motor;

[0067] The first auxiliary unit 502 and the second auxiliary unit 503 can move in the direction of approaching or separating from each other. In this embodiment, the first auxiliary unit 502 and the second auxiliary unit 503 are respectively driven independently by cylinders 508. In addition, different conveying width adjustments are required for egg tarts 1 with different stacking heights. Therefore, a width adjustment mechanism is also provided. The width adjustment mechanism includes a positive and negative thread screw adjustment mechanism. More specifically, the positive and negative thread screw adjustment mechanism includes a positive and negative thread screw and a handwheel 509 (or a positive and negative thread screw and a motor, only the difference between manual and automatic). The moving blocks on the positive and negative threads of the positive and negative thread screw are fixedly connected to the mounting bases where the first auxiliary unit 502 and the second auxiliary unit 503 are located respectively. The width between the two mounting bases is adjusted by rotating the handwheel 509, thereby adjusting the distance between the first auxiliary unit 502 and the second auxiliary unit 503 to adapt to egg tarts 1 with different stacking heights;

[0068] In view of the existence of the clamping unit, especially the upper clamping plate 404 in the clamping unit, after placing the egg tart 1 on the main conveying mechanism 501, if the auxiliary unit 1 502 and the auxiliary unit 2 503 are directly moved close to each other and pressed against the two ends of the tray, it is difficult for the auxiliary conveying mechanism corresponding to the upper clamping plate 404 clamped on the upper tray 2 to successfully complete the docking support of the egg tart 1. In this embodiment, the auxiliary unit 1 502 and the upper clamping plate 404 are used as an example for explanation. The auxiliary unit 1 502 directly presses against the upper clamping plate 404, resulting in the upper clamping plate 404 being difficult to be pulled out from between the auxiliary unit 1 502 and the upper tray 2. If the upper clamping plate 404 is pulled out first and then the auxiliary unit 1 502 is moved so that the auxiliary unit 1 502 presses against the upper tray 2, during the period when the egg tart 1 loses the clamping of the clamping plate, the multiple egg tarts 1 in the stacked state and supported only by the tray may be scattered. Therefore, in order to achieve the purpose of both pulling out the clamping plate and preventing the egg tart 1 from spreading, a support member 510 corresponding to the clamping unit and capable of being retracted is provided on one side of the auxiliary unit 502. Figure 13 As shown, the support member 510 includes a telescopic drive mechanism and a support block arranged on the telescopic rod of the telescopic drive mechanism, and the telescopic drive mechanism includes a telescopic electric cylinder. In accordance with the above, in view of the fact that three groups of clamping units are arranged on the tray body 402, six stacks of egg tarts 1 can be delivered to the clamping and conveying device 500 at the same time, and therefore, six support members 510 are correspondingly arranged. Similarly, the multiple support members 510 can be driven separately and synchronously, and the synchronous movement of the multiple support members 510 can also be achieved by setting a connecting plate with reference to the synchronous driving method between the aforementioned multiple groups of clamping units. In accordance with the above, in order to facilitate the support member 510 to pass through the conveyor belt of the auxiliary unit 502 and abut against the upper tray 2, the conveyor belt in the auxiliary unit 502 adopts a two-section type, and there is a gap in the middle of the two sections of the conveyor belt to facilitate the support member 510 to pass through;

[0069] In accordance with the above, the two pallet conveying units include two clamping conveying devices 500, and the clamping conveying devices 500 are connected to the spacing adjustment conveying device 700. In order to reduce the conveying cost, the two clamping conveying devices 500 are conveyed to the same spacing adjustment conveying device 700. Therefore, Figure 14 As shown, two clamping conveying devices 500 are arranged on a fourth linear module 600, for example, the fourth linear module 600 is a linear motor module. The linear motor module is used to move the two clamping conveying devices 500 in turn to the position where they are docked with the spacing adjustment conveying device 700. In this embodiment, the moving center of the linear motor module is the docking position;

[0070] The spacing-adjustable conveying device 700 includes a plurality of main path conveying mechanisms that are sequentially connected for conveying. The main path conveying mechanism includes a main conveying mechanism 501 that is the same as the clamping conveying device 500, and auxiliary conveying mechanisms that are located on both sides of the main conveying mechanism 501, abut against the tray, and are synchronously conveyed with the main conveying mechanism 501. The auxiliary conveying mechanism includes an auxiliary unit 502 and an auxiliary unit 503 that are oppositely arranged. Among them, the synchronous conveying method refers to the synchronous conveying in the aforementioned clamping conveying device 500. In addition, the auxiliary unit 502 and the auxiliary unit 503 can also perform width adjustment, and the width adjustment refers to the width adjustment mechanism of the auxiliary unit 502 and the auxiliary unit 503 in the aforementioned clamping conveying device 500. The main path conveying mechanism at the conveying end of the spacing-adjustable conveying device 700 is the reference conveying mechanism 701, and the main path conveying mechanisms in the spacing-adjustable conveying device 700 other than the reference conveying mechanism 701 are the adjustment conveying mechanisms 702. A sensor for monitoring the material conveying situation is provided on at least one adjustment conveying mechanism 702;

[0071] In this embodiment, continue as Figure 14 shown, there are three main path conveying mechanisms. The one close to the clamping conveying device 500 is the first adjustment conveying mechanism 702, and the one located between the first adjustment conveying mechanism 702 and the reference conveying mechanism 701 is the second adjustment conveying mechanism 702. A sensor for monitoring the material conveying situation is provided at the conveying end of the first adjustment conveying mechanism 702. In this embodiment, the sensor is an infrared sensor. According to the setting method of this embodiment, the first adjustment conveying mechanism 702 is used to receive and convey the egg tart 1 and monitor the conveying situation of the egg tart 1 with the help of the sensor, without speed adjustment, and the second adjustment conveying mechanism 702 performs speed adjustment. In other embodiments, the sensor can be provided at the conveying front end of the first adjustment conveying mechanism 702. In this way, the first adjustment conveying mechanism 702 can also perform speed adjustment, and the first adjustment conveying mechanism 702 and the second adjustment conveying mechanism 702 form multi-stage speed adjustment. Of course, several more adjustment conveying mechanisms 702 can be provided according to needs. In this embodiment, only the first method is described.

[0072] According to the supporting and conveying production line described in this embodiment, the following conveying method can be obtained:

[0073] 1) The stacking table 101 moves to the corresponding station of the lower tray loading unit 201 under the drive of the first linear module 102;

[0074] 2) The vacuum suction cup 2037 rises under the action of the lifting cylinder until the suction cup on the vacuum suction cup 2037 abuts against the lower side of the bottommost lower tray 3. The vacuum suction cup 2037 is activated, and the bottommost lower tray 3 is adsorbed by the vacuum suction cup 2037. When the lifting cylinder drives the vacuum suction cup 2037 to descend, the lower tray 3 follows the vacuum suction cup 2037 to descend, breaking through the block of the elastic sheet 2036. Subsequently, the elastic sheet 2036 immediately returns to the blocking state, so that the subsequent lower trays 3 on the tray rack 2031 are blocked by the elastic sheet 2036 to prevent them from falling. After the lower tray 3 gets rid of the blocking effect of the elastic sheet 2036, the vacuum suction cup 2037 closes the suction force on the lower tray 3, the disk pushing unit 2035 extends, and the pushing moving disk 2033 is pushed close to the stacking table 101. Then, with the help of the tray pushing unit 2034, the lower tray 3 is pushed onto the stacking table 101, completing the feeding of one lower tray 3. Subsequently, the tray pushing unit 2034 and the disk pushing unit 2035 return to their original positions to facilitate the next round of tray feeding;

[0075] 3) After the feeding of the lower tray 3 is completed, under the drive of the first linear module 102, the stacking table 101 moves to the working position corresponding to the material feeding device;

[0076] 4) The two sets of limiting groups 300 approach each other under the action of the double-rod bidirectional cylinder 302 to provide limitation for the stacking of the egg tarts 1. The feeding machine clamps the egg tarts 1 and stacks them layer by layer;

[0077] 5) After the stacking of the egg tarts 1 is completed, under the drive of the second linear module 103, the pressing block 1042 presses against the uppermost egg tart 1. The two sets of limiting groups 300 move away from each other under the action of the double-rod bidirectional cylinder 302 to provide an escape space for the stacking table 101 to escape from the middle of the limiting groups 300;

[0078] 6) Under the drive of the first linear module 102, the stacking table 101 is conveyed to the working position corresponding to the upper tray feeding unit 202. The second linear module 103 drives the pressing block 1042 to rise and withdraw from above the stacking table 101 to facilitate the subsequent feeding of the upper tray 2;

[0079] 7) The feeding of the upper tray 2 is carried out, and the feeding steps of the upper tray 2 refer to 2);

[0080] 8) After the feeding of the upper tray 2 is completed, the supporting situation of the upper tray for the egg tarts 1 is as shown in Figure 15 As shown. Under the drive of the second linear module 103, the pressing block 1042 presses against the egg tarts 1 again to prevent the egg tarts 1 from toppling during transportation. Then, under the drive of the first linear module 102, the stacking table 101 is conveyed to the working position corresponding to the flipping device 400;

[0081] 9) Driven by the lifting mechanism 1014, the lifting plate 1012 descends. Supported by the foot pads 1013, the height of the lower tray 3 remains unchanged, creating a space between the lower tray 3 and the lifting plate 1012 that facilitates the insertion of the lower clamping plate 405.

[0082] 10) Driven by the three-axis linear module, the turning plate moves to the blanking station. The lower clamping plate 405 is inserted below the lower tray 3, and at the same time, the upper clamping plate 404 is inserted above the upper tray 2. The upper clamping plate 404 and the lower clamping plate 405 are driven to move towards each other until the upper tray 2 and the lower tray 3 are clamped. After that, the lifting plate 1012 returns to its original position under the drive of the lifting mechanism 1014 to prepare for the next feeding of the lower tray 3.

[0083] 11) After clamping, driven by the reduction motor, the disk body 402 is rotated 90° relative to the mounting arm 401, so that the side holding the egg tart 1 faces downward, and the turning plate is conveyed directly above the clamping and conveying device 500 with the help of three groups of linear modules.

[0084] 12) The support member 510 and the auxiliary two unit 503 opposite to the support member 510 respectively abut against the upper tray 2 and the lower tray 3. After the support member 510 and the auxiliary two unit 503 achieve the abutment against the tray, the upper clamping plate 404 and the lower clamping plate 405 are withdrawn from the tray. The turning plate returns to the blanking station again under the drive of the three-axis linear module, and the disk body 402 rotates 90° in the reverse direction to return to the original clamping position for the next round of feeding.

[0085] 13) The auxiliary one unit 502 on the side where the support member 510 is located moves towards the auxiliary two unit 503 until the conveyor belt on the auxiliary one unit 502 abuts against the upper tray 2. The support member 510 withdraws, and the egg tart 1 is clamped and conveyed through the auxiliary one unit 502 and the auxiliary two unit 503.

[0086] 14) The clamping and conveying device 500 is conveyed to the position docked with the spacing adjustment conveying device 700 through the linear motor module, and the egg tart 1 and the trays at both ends are transferred into the spacing adjustment device together for continuous clamping and conveying.

[0087] 15) The infrared sensor on the first adjustment conveying mechanism 702 in the spacing adjustment device monitors the conveying spacing of the egg tart 1, and the second adjustment conveying mechanism 702 is used for speed matching. Finally, it is conveyed to the next station by the reference conveying mechanism 701. For example, if the conveying spacing is too large, the second adjustment conveying mechanism 702 accelerates the conveying at a conveying speed faster than the reference conveying mechanism 701. If the conveying spacing is too small, the second adjustment conveying mechanism 702 decelerates the conveying at a conveying speed slower than the reference conveying mechanism 701 to achieve the adjustment of the conveying spacing.

[0088] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
