Description

Technical Field

[0001] This invention belongs to the field of medical dressing production equipment, and specifically relates to a multi-channel piece transfer system and method. Background Technology

[0002] Medical dressings (foam dressings and hydrogel dressings) are processed by laminating machines and slitting machines, and then need to be transported to a packaging system for packaging. With the rapid upgrading of production equipment, the production speed of medical dressings has greatly increased. The volume of medical dressings output from the slitting machine is relatively large, and the output frequency is also relatively high. The output belt of the medical dressing slitting machine runs at a relatively high speed, and the medical dressings are arranged very densely. If they are directly transported to the packaging system for packaging, the packaging speed of the packaging machine cannot match the transport speed of the output belt of the medical dressing slitting machine. Therefore, a transfer mechanism needs to be designed to divide the medical dressings into multiple channels for transmission, with the aim of increasing the number of packaging machines and thus improving packaging efficiency. Currently, the equipment capable of performing the above transfer includes robotic arms or other transfer grippers, but they share a common problem: the transfer speed is not fast enough, and the reciprocating frequency of the robotic arms or other transfer grippers is too low, making it impossible to quickly divide the medical dressings. Summary of the Invention

[0003] In view of the technical problems existing in the background art, the present invention provides a multi-channel segmented transfer system and method, in which each discharge conveyor is equipped with a negative pressure rotary material handling device and a reciprocating material feeding device, and each discharge conveyor is equipped with a packaging machine (or a material collection device or other equipment connected to the discharge conveyor). This allows multiple packaging machines to package medical dressings on the same infeed conveyor. The negative pressure rotary material handling device can be equipped with multiple grooved suction heads; the more grooved suction heads, the faster the transfer speed. Multiple grooved suction heads move in a circular motion around the same axis, greatly reducing the time interval between each material pick-up by two adjacent grooved suction heads on the infeed conveyor. This significantly improves transfer efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A multi-channel segmented transfer system includes an infeed conveyor and an outfeed conveyor. Multiple outfeed conveyors are provided, and each conveyor or multiple outfeed conveyors is equipped with a corresponding negative pressure rotary material handling device. The negative pressure rotary material handling device cooperates with a reciprocating material feeding device. The negative pressure rotary material handling device includes a grooved suction head for sucking up material from the infeed conveyor. The reciprocating material feeding device includes a feeding blade for displacing material from the grooved suction head onto the outfeed conveyor.

[0006] In a preferred embodiment, the negative pressure rotary material handling device further includes a rotary bracket, on which a passive pulley is provided. The passive pulleys on multiple rotary brackets are connected to a drive pulley via a belt. The drive pulley is driven to rotate by a motor of the negative pressure rotary material handling device. Each rotary bracket has one or more grooved suction heads. The grooved suction head is provided with an adsorption hole, which is connected to the negative pressure air passage.

[0007] In a preferred embodiment, the grooved suction head is driven to move up and down reciprocally by a suction head lifting mechanism. When the grooved suction head moves above the feeding conveyor, the suction head lifting mechanism drives the grooved suction head to move downward and adsorb the material.

[0008] In a preferred embodiment, the suction head lifting mechanism includes a circular track, which is adapted to rollers. The rollers are connected to a rotating bracket, and the rotating bracket drives the rollers to move in a circular motion along the circular track. Each roller corresponds to a grooved suction head and moves up and down synchronously. A downward-curving bend is provided on the circular track, and the bend is located above the feeding conveyor.

[0009] In a preferred embodiment, the roller is connected to the lifting rod, and the lifting rod is connected to the rotating bracket via an anti-rotation bushing; the lifting rod is provided with a negative pressure air passage, and the negative pressure air passage of each lifting rod is connected to the main air passage, which is located inside the main shaft of the rotating bracket and is connected to a negative pressure generator.

[0010] In a preferred embodiment, the suction head is provided with a slot, and the feeding plate is provided with a insert that matches the slot. The feeding plate is driven to move up and down by a feeding plate lifting mechanism.

[0011] In a preferred embodiment, the material-feeding plate lifting mechanism includes a material-feeding plate lifting mechanism drive motor, which drives a cam to rotate via a rotating shaft. The cam is hinged to a connecting rod, the connecting rod is hinged to a slider, the slider is slidably engaged with a slide block, and the slider is connected to the material-feeding plate.

[0012] In a preferred embodiment, the insert of the feed piece has an arc-shaped structure.

[0013] In a preferred embodiment, the discharge conveyor includes a conveyor chain with several scrapers evenly spaced on the conveyor chain and L-shaped guard plates on both sides of the conveyor chain. The scrapers are used to drive the material to slide on the L-shaped guard plates.

[0014] A fragment transfer method for a multi-channel fragment transfer system includes the following steps:

[0015] Step S1: Use a feeding conveyor to transport the materials that need to be transferred;

[0016] Step S2: When the material moves to the bottom of the grooved suction head, the suction head lifting mechanism is used to move the grooved suction head downward and the material is adsorbed onto the grooved suction head by negative pressure.

[0017] Step S3: The suction head lifting mechanism moves the grooved suction head upward;

[0018] Step S4: The negative pressure rotary material handling device drives the rotating bracket to rotate, and the rotating bracket drives the grooved suction head to rotate.

[0019] Step S5: When the slotted suction head reaches the feeding plate, the insert of the feeding plate is inserted into the slot from the side wall of the slotted suction head.

[0020] Step S6: The material feeding plate lifting mechanism drive motor drives the material feeding plate to move downward and push the material from the grooved suction head to the discharge conveyor;

[0021] Step S7: The negative pressure rotary material handling device drives the rotating bracket to continue rotating. After the grooved suction head leaves the running trajectory of the material handling plate, the material handling plate lifting mechanism drives the material handling plate to move upward and run until the initial state in step S6.

[0022] Step S8: Repeat steps S2-S7 to achieve continuous rotating material handling and segmentation.

[0023] The present invention can achieve the following beneficial effects:

[0024] 1. The feeding conveyor is equipped with multiple discharging conveyors. Each discharging conveyor is equipped with a negative pressure rotary material handling device and a reciprocating material feeding device. Each discharging conveyor is also equipped with a packaging machine. This allows multiple packaging machines to be added to package the medical dressings on the same feeding conveyor.

[0025] 2. Multiple slotted suction heads can be installed on the negative pressure rotary feeding device. The more slotted suction heads there are, the faster the transfer speed. Multiple slotted suction heads move in a circular motion around the same axis, which greatly reduces the time interval between each time two adjacent slotted suction heads pick up material on the feeding conveyor. This helps to greatly improve the transfer efficiency.

[0026] 3. The reciprocating feeding device works in conjunction with the negative pressure rotary feeding device to process powder. The reciprocating feeding device only performs small-range reciprocating movements within the same working area, enabling multiple reciprocating movements in a short period of time, resulting in a high reciprocating frequency. Combined with the continuously rotating grooved suction head, it can achieve high-frequency dispensing, making the dispensing of medical dressings fast and efficient. Attached Figure Description

[0037] Example 1:

[0038] Preferred solutions include Figures 1 to 7 As shown, a multi-channel segmented transfer system includes a feeding conveyor 1 and a discharging conveyor 2. There are multiple discharging conveyors 2, and each or multiple discharging conveyors 2 is equipped with a negative pressure rotary material handling device 3. The negative pressure rotary material handling device 3 cooperates with a reciprocating material feeding device 4. The negative pressure rotary material handling device 3 and the reciprocating material feeding device 4 are mounted on a frame. The negative pressure rotary material handling device 3 includes a grooved suction head 301, which is used to pick up material from the feeding conveyor 1. The reciprocating material feeding device 4 includes a material feeding blade 401, which is used to push the material from the grooved suction head 301 onto the discharging conveyor 2.

[0039] The number of grooved suction heads 301 is at least one; in this embodiment, there are three grooved suction heads 301. If it is necessary to increase the transfer speed, more than three grooved suction heads 301 can be set. In this embodiment, the feeding conveyor 1 is the output belt of a medical dressing slitting machine.

[0040] In this embodiment, there are two discharge conveyors 2, and correspondingly, there are two negative pressure rotary feeding devices 3 and two reciprocating feeding devices 4, with a discharge conveyor 2 located below each reciprocating feeding device 4. Both negative pressure rotary feeding devices 3 pick up material from the same feeding conveyor 1 and discharge it onto the discharge conveyor 2 respectively. The material in this embodiment is medical dressing, which has a sheet-like structure, and the medical dressings are placed at equal intervals on the feeding conveyor 1. The grooved suction head 301 is a square metal head with three slots at its bottom.

[0041] Furthermore, the negative pressure rotary material handling device 3 in this embodiment also includes a rotary bracket 302, on which a passive pulley 303 is provided. Multiple passive pulleys 303 on the rotary brackets 302 are connected to a driving pulley via a belt. The driving pulley is rotated by the negative pressure rotary material handling device drive motor 5. Each rotary bracket 302 has one or more grooved suction heads 301. The grooved suction head 301 has an adsorption hole that connects to the negative pressure air passage. The "pulley 303" and "belt" mentioned in this embodiment can be replaced by other equivalent transmission components. Any replacement using other conventional means based on this embodiment is within the scope of protection of this invention.

[0042] The negative pressure rotary material handling device drives the motor 5 to rotate the rotating bracket 302, which in turn drives the grooved suction head 301 to rotate. The grooved suction head 301 rotates continuously and works in conjunction with the reciprocating feeding device 4 to cut and unload the material into pieces.

[0043] Furthermore, the grooved suction head 301 is driven to move up and down reciprocally by the suction head lifting mechanism. When the grooved suction head 301 runs above the feeding conveyor 1, the suction head lifting mechanism drives the grooved suction head 301 to move downward and adsorb the material.

[0044] The suction head lifting mechanism is used to drive the grooved suction head 301 to move up and down. When the medical dressing is delivered to the area below the grooved suction head 301, the grooved suction head 301 moves downward. The suction head lifting mechanism can be a cylinder, hydraulic cylinder, or other similar lifting device.

[0045] Furthermore, in order to ensure that the grooved suction head 301 can move downward at the same point each time, the suction head lifting mechanism of the present invention adopts the following: the suction head lifting mechanism includes an annular track 304, the annular track 304 is adapted to rollers 305, the rollers 305 are connected to a rotating bracket 302, and the rotating bracket 302 drives the rollers 305 to move in a circle along the annular track 304; each roller 305 corresponds to a grooved suction head 301 and moves up and down synchronously; a downward curved path 307 is provided on the annular track 304, and the curved path 307 is located above the feeding conveyor 1.

[0046] The circular track 304 is fixed and is supported by a separate support mechanism. The rotating bracket 302 drives the roller 305 and the grooved suction head 301 to rotate together. The roller 305 moves along the circular track 304. When it reaches the curve 307, the roller 305 moves downward and drives the grooved suction head 301 to move downward.

[0047] Furthermore, the roller 305 is connected to the lifting rod 306, and the lifting rod 306 is connected to the rotating bracket 302 through the anti-rotation bushing; the lifting rod 306 is provided with a negative pressure air passage, and the negative pressure air passage of each lifting rod 306 is connected to the main air passage, which is located in the main shaft of the rotating bracket 302 and is connected to the negative pressure generator.

[0048] The lifting rod 306 can slide up and down. The design purpose of the lifting rod 306 is: 1. to connect the grooved suction head 301 and the roller 305; 2. the lifting rod 306 is a hollow structure, communicating with the suction hole of the grooved suction head 301. Simultaneously, the internal space of multiple lifting rods 306 communicates with the main air passage. The main air passage can be formed by opening channels within the rotating bracket 302 and the main shaft, or by laying flexible hoses. Since the rotating bracket 302 is rotatable, a union joint can be installed at the end of the main shaft for connecting a negative pressure generator.

[0049] Furthermore, the slot suction head 301 is provided with a slot 308, and the material feeding plate 401 is provided with an insert that matches the slot 308. The material feeding plate 401 is driven to move up and down by the material feeding plate lifting mechanism.

[0050] The material-pushing plate 401 is used to move from the side of the slot 308 into the slot 308. There is relative movement between the slot 308 and the material-pushing plate 401, but the material-pushing plate 401 does not rotate, but only makes up-down reciprocating movements. The material-pushing plate 401 pushes the medical dressing downwards from top to bottom and pushes the medical dressing onto the discharge conveyor 2.

[0051] Furthermore, the material lifting mechanism can be a cylinder, a hydraulic cylinder, or other similar lifting device. However, in order to ensure the coordination time with the negative pressure rotating material taking device 3, the material lifting mechanism in this invention is preferably: the material lifting mechanism includes a material lifting mechanism drive motor 402, the material lifting mechanism drive motor 402 drives the cam 403 to rotate through the rotating shaft, the cam 403 is hinged to the connecting rod 404, the connecting rod 404 is hinged to the slider 405, the slider 405 is slidably engaged with the slide block 406, and the slider 405 is connected to the material lifting piece 401.

[0052] Furthermore, the insert of the feed plate 401 has an arc-shaped structure. Its curvature is designed according to the rotation radius of the grooved suction head 301.

[0053] Furthermore, the discharge conveyor 2 includes a conveyor chain, on which several scrapers are arranged at equal intervals, and L-shaped guard plates are provided on both sides of the conveyor chain. The scrapers are used to drive the material to slide on the L-shaped guard plates.

[0054] A fragment transfer method for a multi-channel fragment transfer system includes the following steps:

[0055] Step S1: Use the feeding conveyor 1 to transport the material to be transferred;

[0056] Step S2: When the material runs to the bottom of the grooved suction head 301, the suction head lifting mechanism is used to move the grooved suction head 301 downward and the material is adsorbed onto the grooved suction head 301 by the negative pressure suction.

[0057] Step S3: The suction head lifting mechanism moves the grooved suction head 301 upward;

[0058] Step S4: The negative pressure rotary material handling device drive motor 5 drives the rotary bracket 302 to rotate, and the rotary bracket 302 drives the grooved suction head 301 to rotate.

[0059] Step S5: When the slotted suction head 301 runs to the feeding plate 401, the insert of the feeding plate 401 is inserted into the slot from the side wall of the slotted suction head 301.

[0060] Step S6: The material feeding plate lifting mechanism drive motor 402 drives the material feeding plate 401 to move downward and push the material away from the grooved suction head 301 to the discharge conveyor 2;

[0061] Step S7: The negative pressure rotary material handling device drive motor 5 drives the rotary bracket 302 to continue rotating. After the grooved suction head 301 leaves the running trajectory of the material handling plate 401, the material handling plate lifting mechanism drive motor 402 drives the material handling plate 401 to move upward and run until the initial state in step S6.

[0062] Step S8: Repeat steps S2-S7 to achieve continuous rotating material handling and segmentation.

[0063] As a preferred solution, such as Figure 8 As shown, the bottom of the insert of the dressing has a baffle. The baffle is used to limit the position of the medical dressing.

[0064] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The scope of protection of the present invention should be defined as the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
