Description

Technical Field

[0001] The utility model relates to the field of material feeding and positioning, in particular to a feeding and positioning device for strip-shaped soft materials. Background Art

[0002] In the production and manufacturing process of some strip-shaped soft materials, such as condoms, balloons, etc., it is often necessary to place these strip-shaped soft materials in a fixed orientation, such as with the open end facing downwards, and then perform subsequent electrical inspection processes to determine whether these strip-shaped soft materials are qualified. In the prior art, manual feeding and placement of strip-shaped soft materials are adopted. Although it is relatively accurate, the cost is too high; when using a machine to feed and place strip-shaped soft materials, since the strip-shaped soft materials are placed in the storage bin in a disorderly manner before feeding, and their material is soft and they will be placed in various postures, so how to feed and place the soft materials in a fixed orientation is an urgent problem to be solved for the automated processing of strip-shaped soft materials.

The material suction and transfer mechanism is conducive to adsorbing the strip-shaped soft materials adsorbed on the feeding mechanism and transferring them to the positioning mechanism.

[0033] As Figure 1 and Figure 2 shown, a strip-shaped flexible material feeding and positioning device includes: a material suction and transfer mechanism 1, a feeding mechanism 2, a support mechanism 3, a positioning mechanism 4, a flipping mechanism 5, a slide rail mechanism 6 and a control mechanism; the positioning mechanism 4, the flipping mechanism 5 and the slide rail mechanism 6 are all installed on the support mechanism 3, the feeding mechanism 2 is detachably installed on the slide rail mechanism 6, the material suction and transfer mechanism 1 is slidably installed on the slide rail mechanism 6 to transfer the material adsorbed by the feeding mechanism 2 to the positioning mechanism 4, the material suction and transfer mechanism 1, the feeding mechanism 2 and the flipping mechanism 5 are all connected to an air pump, and the control mechanism is connected to the air pump and the slide rail mechanism 6.

[0034] Among them, it should be noted that: in the technical solution of the present utility model, since the structures of strip-shaped flexible materials such as condoms or balloons are open at one end and closed at the other end, and a hanging ring is provided at the open end, when these strip-shaped flexible materials enter the positioning mechanism 4, if the open end faces upward, these strip-shaped flexible materials can be hung in the positioning mechanism 4 through the hanging ring;

[0035] Since the material is flexible, when any part of the material is adsorbed by the material suction and transfer mechanism 1, the material can be bent, and the open end either faces upward or downward;

[0036] In the technical solution of the present utility model, the air pump is connected to the material suction and transfer mechanism 1, the feeding mechanism 2, and the flipping mechanism 5 through valves, so as to control the on-off of the air paths of the components that require air in the material suction and transfer mechanism 1, the feeding mechanism 2, and the flipping mechanism 5. The control mechanism is connected to the valves that control the on-off of the air paths of the components that require air in the material suction and transfer mechanism 1, the feeding mechanism 2, and the flipping mechanism 5, and realizes the on-off of the air path by controlling the on-off of the valves, and at the same time enables the multiple components that require air to work without interfering with each other. Specifically, the components that require air in the technical solution of the present utility model are the material suction cylinder 11, the material suction disc 13, the feeding cylinder 21, the feeding disc 23, the horizontal sliding table 51, and the clamp cylinder 521;

[0037] The control mechanism is a PLC (Programmable Logic Controller), and the connections and controls between the control mechanism and the valves that control the on-off of the air path in the air pump and the slide rail mechanism 6 are all prior arts.

[0038] The beneficial effects of the present utility model are as follows: the support mechanism is beneficial to placing the material bin and provides support for the installation of the positioning mechanism, the flipping mechanism, and the slide rail mechanism. The feeding mechanism is beneficial to adsorbing the strip-shaped flexible materials placed in the material bin and moving them upward. The material suction and transfer mechanism is beneficial to adsorbing the strip-shaped flexible materials adsorbed in the feeding mechanism and transferring them to the positioning mechanism. If the material enters the positioning mechanism with the open end facing downward at this time, the material smoothly passes through the positioning mechanism. If the material enters the positioning mechanism with the open end facing upward, the material is hung in the positioning mechanism, and the flipping mechanism adjusts the material to have the open end facing downward and then passes through the positioning mechanism. Finally, the strip-shaped flexible materials in the material bin are all positioned with the open end facing downward, improving the efficiency of material feeding and positioning and reducing the labor cost.

[0039] Preferably, as Figure 1As shown in the figure, the support mechanism 3 includes: a support frame 31, a first workbench 32, a second workbench 33, a loading positioning frame 34, and a connecting frame 35; both the first workbench 32 and the second workbench 33 are plate-like structures arranged at the top of the support frame 31. The positioning mechanism 4 is arranged between the first workbench 32 and the second workbench 33 and is connected to the first workbench 32. The flipping mechanism 5 is installed on the second workbench 33. The connecting frame 35 is vertically installed at one end of the first workbench 32 away from the positioning mechanism 4. The slide rail mechanism 6 is arranged at the top of the connecting frame 35. The loading positioning frame 34 is installed on the side wall of the connecting frame 35.

[0040] The beneficial effects of adopting the above preferred solution are as follows: The support frame is beneficial for providing support for the entire device. The first workbench is beneficial for providing support for the positioning mechanism. The second workbench is beneficial for providing support for the flipping mechanism. The loading positioning frame, in cooperation with the loading mechanism and the control mechanism, is beneficial for adsorbing the materials in the bin and lifting them to a fixed height, thus facilitating the adsorption and transportation of the material suction and transportation mechanism. The connecting frame is beneficial for providing support for the installation of the slide rail mechanism.

[0041] Preferably, as Figure 3 shown in the figure, the loading positioning frame 34 includes: a mounting bracket 341, a positioning tube 342, and a first sensor mounting bracket 343. The mounting bracket 341 is connected to the side wall of the connecting frame 35. The first sensor mounting bracket 343 is a U-shaped plate-like structure arranged at the bottom end of the mounting bracket 341. The positioning tube 342 is inclinedly arranged on the mounting bracket 341, and its bottom end is arranged in the middle of the first sensor mounting bracket 343.

[0042] The beneficial effects of adopting the above preferred solution are as follows: The mounting bracket is beneficial for arranging the positioning tube in an inclined posture and providing support for the installation of the first sensor mounting bracket. The inclined arrangement of the positioning tube is beneficial for avoiding interference between the loading mechanism and the positioning tube when the loading mechanism moves downward.

[0043] Preferably, as Figure 3 shown in the figure, a first light sensor is arranged at the bottom end of the first sensor mounting bracket 343. The first light sensor is connected to the control mechanism; the positioning tube 342 is a tubular structure with an open side wall at one end facing the loading mechanism 2.

[0044] The beneficial effects of adopting the above preferred solution are as follows: The first photosensor cooperating with the control mechanism is conducive to enabling the material to be displaced upward to a certain fixed height during the process of the feeding mechanism adsorbing the material and displacing upward, facilitating the subsequent adsorption and transfer of the material by the material suction and transfer mechanism; one end side wall of the positioning tube facing the feeding mechanism is open, on the one hand, it is conducive to avoiding interference between the feeding mechanism and the positioning tube when the feeding mechanism displaces downward to adsorb the material in the bin, and on the other hand, it is conducive to avoiding interference between the material suction and transfer mechanism and the positioning tube when adsorbing the material.

[0045] Preferably, as Figure 1 shown, the slide rail mechanism 6 includes: a sliding support block 61, a sliding block 62, and a slide rail 63; the sliding support block 61 is horizontally arranged at the top end of the connecting frame 35, the slide rail 63 is arranged at the top end of the sliding support block 61, and the sliding block 62 is slidably connected to the slide rail 63.

[0046] Among them, it should be noted that: in the technical solution of the present invention, the slide rail mechanism 6 further includes a motor for driving the sliding block 62 to displace on the slide rail 63, and the motor is connected to the control mechanism.

[0047] The beneficial effects of adopting the above preferred solution are as follows: The sliding of the sliding block on the slide rail is conducive to driving the material suction and transfer mechanism to move along the slide rail, and then transferring the material from the feeding positioning frame to the positioning mechanism.

[0048] Preferably, as Figure 3 shown, the feeding mechanism 2 includes: a feeding cylinder 21, a feeding connecting plate 22, and a feeding tray 23; the feeding cylinder 21 is vertically installed on the side wall of the sliding support block 61, and the output shaft is connected to one end of the feeding connecting plate 22, the feeding tray 23 is arranged at the other end of the feeding connecting plate 22, the feeding tray 23 is arranged above the bottom end of the positioning tube 342, and both the feeding cylinder 21 and the feeding tray 23 are connected to the air pump.

[0049] Among them, it should be noted that: in the technical solution of the present invention, the size of the feeding tray 23 is small, which is conducive to adsorbing the material with a small area between the material and the feeding tray 23 during the adsorption of the material. Coupled with the small mass of the material, it is convenient for the feeding tray 23 to adsorb the material individually.

[0050] The beneficial effects of adopting the above preferred solution are as follows: The feeding cylinder cooperating with the air pump is conducive to pushing out the output shaft, and then pushing the feeding connecting plate and the feeding tray downward into the bin. The feeding tray cooperating with the air pump is conducive to adsorbing the strip-shaped soft materials placed in various postures in the bin.

[0051] Preferably, as Figure 3As shown, the material suction and transfer mechanism 1 includes: a material suction cylinder 11, a material suction connecting plate 12, and a material suction disc 13; the material suction cylinder 11 is vertically installed on the side wall of the sliding block 62, and the output shaft is connected to one end of the material suction connecting plate 12. The material suction disc 13 is arranged at the other end of the material suction connecting plate 12 and corresponds to the bottom end of the positioning pipe 342. Both the material suction cylinder 11 and the material suction disc 13 are connected to the air pump.

[0052] Among them, it should be noted that: in the technical solution of the present invention, the material suction disc 13 corresponds to the open side wall at the bottom end of the positioning pipe 342, and the size of the material suction disc 13 is small, which is beneficial to avoid the material from falling due to the gap between the material suction disc 13 and the soft material when adsorbing the material.

[0053] The beneficial effect of adopting the above preferred solution is that the material suction cylinder cooperates with the air pump to facilitate the pushing out of the output shaft, and then the material suction connecting plate and the material suction disc are pushed downward to correspond to the height where the material adsorbed on the feeding tray stays. The material suction disc cooperates with the air pump to adsorb the material adsorbed on the feeding tray and transfer it to the positioning mechanism under the movement of the slide rail mechanism.

[0054] Preferably, as Figure 4 shown, the positioning mechanism 4 includes: a positioning table 41, two positioning rods 42, a blanking pipe 43, two first connecting plates 44, and a stop rod 45; the positioning table 41 is a housing structure with open front and rear ends. The outer side walls at both ends of the positioning table 41 are respectively connected to the first workbench 32 through the two first connecting plates 44. Both ends of the stop rod 45 are respectively connected to the inner side walls at both ends of the positioning table 41. The blanking pipe 43 is arranged at the bottom end of the positioning table 41 and is communicated with the inside of the positioning table 41. An opening penetrating the top end of the positioning table 41 is arranged in the front-back direction at the top end of the positioning table 41. The two positioning rods 42 are respectively arranged on both sides of the opening, and the two positioning rods 42 form a Y-shaped structure.

[0055] Among them, it should be noted that: in the technical solution of the present invention, the height of the positioning table 41 is adapted to the height where the feeding cylinder 21 stays and the height where the material suction cylinder 11 is pushed downward;

[0056] The blanking pipe 43 is arranged as a tubular structure communicated with the inside of the positioning table 41 because when the material passes through the blanking pipe 43 with the open end downward, the gas will enter the inside of the material from the open end, expand the material, and the material can directly be sleeved on the electric inspection rod below the blanking pipe (when the material is a condom, a conveyor belt and multiple electric inspection rods will be arranged below the blanking pipe, and the conveyor belt drives the electric inspection rod to displace), which is convenient for subsequent electric inspection operations and improves the inspection efficiency.

[0057] The beneficial effects of adopting the above preferred solution are as follows: The front and rear ends of the positioning table are open, which is conducive to the entry of materials and facilitates the operation of the flipping mechanism; the opening at the top of the positioning table cooperates with the Y-shaped positioning rod, which is conducive to the accurate entry of the materials adsorbed by the suction cylinder into the positioning table. At this time, if the opening end of the material is downward, the material is positioned through the feeding pipe. If the opening end of the material is upward, the material is hung on the positioning rod and, with the cooperation of the flipping mechanism, is flipped into a posture with the opening end downward and then positioned through the feeding pipe; the stop rod is conducive to providing a resistance to the material when the flipping mechanism pulls the material backward, preventing the material from being pulled out of the positioning table. When the opening end of the material is pulled into the positioning table, under the action of gravity, the opening end of the material drops, completing the flipping.

[0058] Preferably, as Figure 4 shown, the flipping mechanism 5 includes: a horizontal slide table 51, a fixture assembly 52, a second connecting plate 53, and a second sensor mounting bracket 54; the horizontal slide table 51 is installed on the second workbench 33, the fixture assembly 52 is slidably installed on the horizontal slide table 51, the second connecting plate 53 is installed on the fixture assembly 52, the second sensor mounting bracket 54 is a U-shaped plate structure installed on the second connecting plate 53, the second sensor mounting bracket 54 and the fixture assembly 52 are arranged above and below the stop rod 45 in a one-to-one correspondence, a second photosensor is provided at the bottom end of the second sensor mounting bracket 54, the second photosensor is connected to the control mechanism, and both the horizontal slide table 51 and the fixture assembly 52 are connected to the air pump.

[0059] Among them, it should be noted that: in the technical solution of the present invention, the horizontal slide table 51 is a prior art, and with the cooperation of the air pump, it can realize the pushing out and retracting actions of the push rod, and the fixture assembly 52 is installed on the push rod and advances and retreats with the advance and retreat of the push rod.

[0060] The beneficial effects of adopting the above preferred solution are as follows: The horizontal slide table cooperates with the air pump to drive the fixture assembly and the second photosensor to push out and retract in the front-rear direction. The fixture assembly cooperates with the air pump to clamp and open, thereby clamping the material to be flipped, and cooperating with the retracting action of the horizontal slide table and the blocking action of the stop rod to flip the material. The second photosensor cooperates with the control mechanism to detect the state of the material, so as to judge whether the material needs to be flipped.

[0061] Preferably, as Figure 4 shown, the fixture assembly 52 includes a fixture cylinder 521 and two clamping rods 522. The fixture cylinder 521 is installed on the horizontal slide table 51, and the two clamping rods 522 are horizontally arranged and are both slidably installed on the fixture cylinder 521.

[0062] The beneficial effects of adopting the above preferred solution are as follows: The two clamping rods are horizontally arranged and are both slidably mounted on the clamping fixture cylinder, which is beneficial for the two clamping rods to close and open, thereby realizing the clamping and loosening of the material.

[0063] The working process of the present utility model will be described below through an embodiment:

[0064] As Figures 1 to 4 shown, the silo is placed on the first workbench 32. First, the feeding cylinder 21 is pushed downward to bring the feeding tray 23 close to the material in the silo. After the feeding tray 23 adsorbs the material in the silo, the feeding cylinder 21 moves upward. When the feeding tray 23 moves up and down, it passes through the positioning tube 342. During the process of the feeding tray 23 adsorbing the material and moving upward, the first light sensor will be blocked by the material and generate an electrical signal. When the first light sensor cannot detect the material, it means that the feeding tray 23 has risen in place, and the feeding cylinder 21 stops moving upward and returns.

[0065] Then, the material suction cylinder 11 is pushed downward to push the material suction tray 13 downward to a height corresponding to the material adsorbed by the feeding tray 23. At this time, the sliding block 62 slides on the slide rail 63, so that the material suction tray 13 approaches the material adsorbed by the feeding tray 23 and adsorbs the material. At the same time, the feeding tray 23 cancels the adsorption of the material, and the material is transferred from the feeding tray 23 to the material suction tray 13. At this time, since the material is a strip-shaped soft structure, the material has two states - the open end is downward and the open end is upward.

[0066] Next, the sliding block 62 slides in the reverse direction on the slide rail 63, driving the material adsorbed on the material suction tray 13 to enter the positioning table 41 from the positioning rod 42. If the material enters the positioning table 41 with the open end downward, the material suction tray 13 cancels the adsorption of the material, and the material will pass through the positioning table 41 and the blanking pipe 43 downward with the open end downward to complete the positioning. If the material enters the positioning table 41 with the open end upward, the open end of the material is hung on the positioning rod 42. At this time, since the second light sensor continuously detects the material, the control mechanism determines that the material needs to be flipped. The horizontal sliding table 51 is pushed forward to displace the two mutually separated clamping rods 522 forward, so that the closed end of the material is located between the two clamping rods 522. The two clamping rods 522 approach each other on the clamping fixture cylinder 521 to clamp the closed end of the material. Then the horizontal sliding table 51 retracts backward, and the material will be blocked by the stop rod 45 while moving backward to prevent the material from continuously moving backward out of the positioning table 41. When the open end of the material is pulled down to enter the positioning table 41, the horizontal sliding table 51 moves forward. At this time, the closed end of the material is still clamped by the two clamping rods 522, and the closed end will droop downward under the action of gravity to complete the flipping.

[0067] The last two clamping rods 522 are loosened, and the material with the open end facing downward after flipping will pass downward through the blanking pipe 43 to complete positioning.
