Description
Technical Field
[0001] This utility model belongs to the field of material transfer technology and relates to a transfer component for a pallet transfer bracket. Background Technology
[0002] Chinese utility model patent application number 202322675287.5 discloses a pallet transfer mechanism for a main and branch logistics line, including a transfer shuttle. A large pallet is positioned above the top of the transfer shuttle, and a small pallet is positioned on top of the large pallet. A branch logistics line is positioned on the front of the transfer shuttle, and a push-pull manipulator is connected to the top of the branch logistics line. By using the large pallet to transport materials on the main logistics line and the small pallet to simultaneously pick up and place materials on the branch logistics line, four or more small pallets can be placed on one large pallet. The small pallets are transferred from the large pallet to the branch logistics line using the transfer shuttle and the push-pull manipulator, thereby improving the efficiency of material transportation on the production line. However, this pallet transfer mechanism has a complex structure and high cost, making it difficult to meet the transfer requirements of carrying pallets for electronic components.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] like Figure 4 The carrying tray 1' shown includes a tray body 11', a receiving groove 12' formed on the upper surface of the tray body 11', and a plurality of limiting notches 13' formed on the circumferential surface of the tray body 11'. Due to the presence of the limiting notches 13', two adjacent carrying trays 1' can form corresponding clearance holes through the cooperation of the two limiting notches 13', for accommodating the free end of the stop head 14 described below.
[0021] like Figures 1 to 3 The transfer assembly 2 for the carrier pallet transfer bracket shown is used to sequentially transport the aforementioned carrier pallets 1', and it cooperates with the feeding assembly 1.
[0022] The feeding assembly 1 is used to convey the carrying pallets 1' downstream one by one. In this embodiment, the feeding assembly 1 includes a first support frame 11, a first guide rail groove 12, a first roller 13, a material stop head 14, and a first limiting baffle 15. The first support frame 11 can be a conventional one, such as using multiple profiles connected and assembled to form a sturdy frame structure. There are two first guide rail grooves 12, which are installed on the top of the first support frame 11 and spaced apart. The installation method of the first guide rail grooves 12 on the first support frame 11 can be conventional (such as welding a fastener to the bottom surface of the first guide rail groove 12 and using the fastener to lock it onto the top support rod of the first support frame 11). There are multiple first rollers 13, which are arranged in two rows and rotatably installed in each first guide rail groove 12 (e.g., each first roller 13 is pivotally installed in the first guide rail groove 12, so that the pivots of the first rollers 13 are parallel to each other, the same below); the rotation of the first rollers 13 can be manual (manual means manually pushing the carrying tray 1', thereby driving the rotation of the first rollers 13), but it is preferred to be automatic (automatic means that the first rollers 13 rotate under the direct or indirect drive of the motor, thereby driving the carrying tray 1' to be transported downstream, such as at least one row of first rollers 13 connected together by a transmission chain, and the motor connected to any transmission chain through a transmission gear). The first limiting baffle 15 is installed on the top of the first support frame 11. They are located on the outside of the first guide rail groove 12 (there are also two first limiting baffles 15, which are located on the outside of the two first guide rail grooves 12). The height of the first limiting baffle 15 is higher than the height of the carrying pallet 1' (preferably 1~2cm higher than the upper surface of the carrying pallet 1') to prevent the carrying pallet 1' from being squeezed out of the feeding assembly 1 during conveying.
[0023] The material stop head 14 is swayably mounted between the two first guide rail grooves 12 to block or release the carrying pallets 1' one by one (the swaying method can be any existing conventional method, and a spring is used for reset). For example, a first horizontal frame located below the two first guide rail grooves 12 is mounted on the first support frame 11, and two opposing support seats are mounted in the first horizontal frame. A connecting crossbar is mounted on the two support seats through bearings or a bidirectional rotation damper, so that the connecting crossbar is rotatably mounted on the two support seats and perpendicular to the first guide rail grooves 12. The material stop head 14 is mounted on the connecting crossbar; or a material stop head 14 is mounted on the first support frame 11 or on the ground located below the first horizontal frame. A square base plate is used as the mounting plate, on which a fixed seat with an inclined surface is installed (the angle between the inclined surface and the horizontal plane is preferably 130~160° and the inclined surface faces the stop head 14). A first retaining ring is installed on the inclined surface, and a second retaining ring is installed on the circumferential surface of the stop head 14 (the part facing the fixed seat). One end of a spring is connected to the first retaining ring and the other end is connected to the second retaining ring. At this time, the spring is in its normal state (not stretched and not compressed), and the spring is basically perpendicular to the stop head 14 (the angle formed between the spring and the stop head 14 is preferably 80~100°). The stop head 14 just abuts against the limiting notch 13' of the carrying tray 1'. The principle of blocking or releasing the carrying trays 1' one by one is as follows: In the normal state, the stop head 14 abuts against the limiting notch 13' of the carrying tray 1' to prevent the carrying tray 1' from moving downstream (the stop head 14 is inclined towards the direction of the transfer component 2 of the carrying tray transfer bracket (i.e., Figure 1 (The left side of the image shows the angle between the first bearing unit 212 and the horizontal plane, which is 40-50°). When the empty first bearing unit 212 and the first roller 13 are in the mating position, the motor drives the first roller 13 (one row as the driving roller and the other row as the driven roller) to rotate to transport the bearing pallet 1' downstream, thereby squeezing the stop head 14 to swing slightly until it no longer blocks the bearing pallet 1' (at this time, the spring is compressed; the spring specification needs to match the weight of the bearing pallet 1', that is, it must be able to ensure that the friction between the two rows of first rollers 13 and the bearing pallet 1' is greater than the applied force of the spring deformation, which is a conventional choice in the field). After a bearing pallet 1' is transferred to the first bearing unit 212, the motor stops working, the spring returns to its original position, and the stop head 14 abuts against the limiting notch 13' of the next bearing pallet 1' to prevent it from continuing to move downstream, waiting for the motor to work, and so on.
[0024] In this embodiment, a first sensor and a second sensor (both of which can be commercially available photoelectric sensors, such as Omron E3JK-R4M1) can be set to detect the position of the first carrying unit 212 and whether there is a carrying tray 1' on the first carrying unit 212, respectively. The first sensor, the second sensor, and the motor are all connected to the controller. When the first sensor detects that the first carrying unit 212 has reached the designated position (at the same height as the first roller 13) and the second sensor detects that the first carrying unit 212 is not carrying a carrying tray 1', both the first sensor and the second sensor send signals to the controller (Mitsubishi FX2NC-PLC). The controller then controls the aforementioned motor to move a carrying tray 1' onto the first carrying unit 212. In this embodiment, the spring can also be replaced with an electric telescopic rod. The electric telescopic rod can be connected to the controller, so that the controller controls the extension and retraction of the electric telescopic rod through the aforementioned signals to adjust the position of the stop head 14, thereby realizing the release of the carrying trays 1' one by one, and the control is more precise. The specific installation positions of the first and second sensors can be set according to common sense. When the first support unit 212 reaches the above-mentioned designated position, the first sensor can be installed on the first support frame 211 at a position lower or slightly lower than the first roller 13 and facing upwards to align with the first support unit 212. The second sensor can be installed on the edge of the first support unit 212 through a bracket at a position slightly higher than the first roller 13 and horizontally, also aligned with the first support unit 212.
[0025] The transfer assembly 2 for the pallet transfer bracket includes a lifting mechanism 21, a lowering mechanism 23, a support mechanism 22 connected between the lifting mechanism 21 and the lowering mechanism 23, and a sliding mechanism 24 connected between the lifting mechanism 21 and the lowering mechanism 23. The lifting mechanism 21 is used to lift the pallet 1' carried on the first carrying unit 212 to a high position. The lowering mechanism 23 is used to lower the pallet 1' transferred to the second carrying unit 232 via the sliding mechanism 24 to a low position and transport it downstream.
[0026] The lifting mechanism 21 includes a first support frame 211, a first bearing unit 212, and a first lifting unit 213 that cooperate with each other. The first support frame 211 can be conventionally vertical (e.g., multiple parallel and vertically arranged support rods and multiple support crossbars assembled according to actual needs, the same below). The first bearing unit 212 includes a first base plate 2121 disposed in the first support frame 211, a first feeding ball array 2122 mounted on the first base plate 2121, and a first baffle plate group 2123 mounted on the first base plate 2121 and cooperating with the feeding component 1 (the first baffle plate group 2123 is usually two baffle plates, one corresponding to the feeding component 1 and the other corresponding to the sliding mechanism 24, both of which are higher than the first feeding ball array 2122 by a certain height, preferably 1~3cm). The first material conveying ball array 2122 is an omnidirectional ball transport platform. It can adopt existing conventional methods, such as those disclosed in Chinese Utility Model Patent Application No. 201922336347.4, which can realize the turning and conveying of materials, so that the carrying pallet 1' can be conveyed in a direction perpendicular to the feeding component 1 after being lifted. The first lifting unit 213 only needs to be able to achieve the lifting and resetting of the first bearing unit 212, and can adopt existing conventional methods. In this embodiment, the first lifting unit 213 includes two first transition plates 2131 mounted on the first support frame 211 and arranged vertically opposite each other, a first mounting plate 2132 fixed on each first transition plate 2131, multiple first guide rods 2133 mounted between the two first mounting plates 2132, a first drive rod 2134 mounted between the two first mounting plates 2132, a first lifting block connected to the first drive rod 2134 and slidably mounted on the first drive rod 2134 and the first guide rod 2133, and a first driver connected to the first drive rod 2134 to drive its operation. The first base plate 2121 is mounted on the first lifting block. The first drive rod 2134 can be a transmission screw, a pneumatic rod, or an electric rod. The first driver can be a second motor or a cylinder, thereby driving the first lifting block to slide on the first guide rod 2133. In this embodiment, the first drive rod 2134 is a transmission screw, the first driver is a second motor, and the aforementioned controller is also connected to the second motor. When the first sensor detects that the first support unit 212 has reached the designated position (at the same height as the first roller 13) and the second sensor detects that the first support unit 212 carries the support tray 1', both the first and second sensors send signals to the controller (Mitsubishi FX2NC-PLC). The controller controls the second motor to operate so that the first drive rod 2134 rotates, thereby driving the first lifting block to rise, so that the first base plate 2121 (i.e., the first support unit 212) rises synchronously. In this embodiment, a third sensor (such as an Omron E3JK-R4M1) can be added to the first support frame 211 to sense the position of the first support unit 212 after it has risen.The specific installation position of the third sensor can be set according to common sense. For example, the third sensor can be installed on the top of the first support frame 211, facing downwards, and higher than the sliding mechanism 24. The third sensor is also connected to the aforementioned controller. In addition, the aforementioned controller can also be connected to a PC (disclosed in Chinese Utility Model Patent Application No. 201922336347.4). In this way, when the third sensor detects that the first carrying unit 212 has reached another designated position (the first conveying ball array 2122 of the first carrying unit 212 is slightly higher than the sliding mechanism 24), the third sensor sends a signal to the controller. The controller sends a signal to the PC, causing the PC to send an instruction to the omnidirectional ball transport platform, causing the omnidirectional ball transport platform to rotate at a specific angle (the direction of the lowering mechanism 23) to transport the carrying pallet 1' onto the sliding mechanism 24. When the third sensor detects that the first carrying unit 212 has reached another designated position and the second sensor detects that the first carrying unit 212 is not carrying the carrying pallet 1', the third sensor and the second sensor send signals to the controller. The controller controls the second motor to reset the first carrying unit 212. This cycle continues.
[0027] The structure of the lowering mechanism 23 is generally consistent with that of the lifting mechanism 21, with only minor differences. Therefore, the structure of the lifting mechanism 21 can be referred to. Specifically, the lowering mechanism 23 includes a cooperating second support frame 231, a second bearing unit 232, and a second lifting unit 233. The second bearing unit 232, driven by the second lifting unit 233, moves up and down within the second support frame 231, thus achieving a first position at the top of the second support frame 231 (where it can receive the bearing tray 1'; this first position is slightly lower than the end of the lowering mechanism 24). Figure 2The second support unit 232 includes a second base plate 2321 disposed within the second support frame 231, a second conveying ball array 2322 (also using a conventional omnidirectional ball transport platform) mounted on the second base plate 2321, and a second baffle plate group 2323 mounted on the second base plate 2321 and corresponding to the first baffle plate group 2123 (the second baffle plate group 2323 is usually also two baffle plates, one corresponding to the sliding mechanism 24 and the other corresponding to the discharge port of the descending mechanism 23; they are all higher than the second conveying ball array 2322 by a certain height, preferably 1~3cm). The second support frame 231 has a baffle 2311 located on one side of the second substrate 2321 and cooperating with the second baffle plate assembly 2323. The baffle 2311 also corresponds to the sliding mechanism 24. Thus, when the second bearing unit 232 is in the second position, the second bearing unit 232 is located between a baffle plate (corresponding to the sliding mechanism 24) and the baffle 2311. The baffle 2311 is also higher than the second conveying ball array 2322 by a certain height, preferably 2~5cm, so that only the discharge port of the lowering mechanism 23 ( Figure 3 The open structure on the left side of the second support frame 231 is not limited or obstructed, and the carrying pallet 1' is discharged from here and conveyed downstream.
[0028] The second lifting unit 233 includes two second transition plates mounted on the second support frame 231 and arranged opposite each other, a second mounting plate fixed on each second transition plate, multiple second guide rods 2331 mounted between the two second mounting plates, a second drive rod 2332 mounted between the two second mounting plates, a second lifting block connected to the second drive rod 2332 and slidably mounted on the second drive rod 2332 and the second guide rod 2331, and a second driver connected to the second drive rod 2332 to drive its operation. The second base plate 2321 is mounted on the second lifting block. After the carrying tray 1' is conveyed to the second carrying unit 232 (at this time, the second carrying unit 232 is in the first position), the second lifting unit 233 operates to lower the carrying tray 1' to a set position (at this time, the second carrying unit 232 is in the second position), and achieves turning and conveying under the action of the second conveying ball array 2322. Subsequently, the second lifting unit 233 resets (first position, second position). In this embodiment, the second drive rod 2332 is also a transmission screw, the second driver is a third motor, and the aforementioned controller is also connected to the third motor. To reduce the complexity of control, it is preferable to set the lowering mechanism 23 and the lifting mechanism 21 as linked, that is, using the signals of the aforementioned three sensors, the controller directly controls the operation of the third motor, specifically as follows: when the first carrying unit 212 reaches the designated position, the third motor operates to make the second carrying unit 232 be in the second position; when the first carrying unit 212 reaches another designated position (the first conveying ball array 2122 of the first carrying unit 212 is slightly higher than the lowering mechanism 24), the third motor operates to make the second carrying unit 232 be in the first position, which can reduce the number of sensors used.
[0029] The sliding mechanism 24 includes two second guide rail grooves 241 (as above) installed between the lifting mechanism 21 and the lowering mechanism 23 and spaced apart, a plurality of second rollers 242 rotatably installed in each second guide rail groove 241, and a second limiting baffle 243 located outside the second guide rail groove 241. The end of the second guide rail groove 241 connected to the lifting mechanism 21 is higher than the end connected to the lowering mechanism 23, so that the angle formed between the second guide rail groove 241 and the horizontal plane is 1~5°. This ensures that the carrying pallet 1' moves from the lifting mechanism 21 to the lowering mechanism 23 and the moving speed is not too fast.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
