DETAILED DESCRIPTION

[0038] One preferred embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0039] Referring to Figures 1 to 6 The present application provides a foam tray cavity waste removal equipment, which comprises a workbench 1, and a foam feeding device 2, a foam positioning device 3, a cavity waste removal device 4, a waste collection device 5 and a control device 6 for controlling the above-mentioned devices to work cooperatively, which are arranged on the workbench 1. The workbench 1 is provided with a processing station and a waste collection station, and the processing station is defined to have a first side, a second side, a third side and a fourth side. The first side is opposite to the third side, and the second side is opposite to the fourth side. The foam tray provided by the present application has a square sheet structure, and a plurality of cavities are arranged in a linear array on the tray.

[0040] Example 1.

[0041] The foam positioning device 3 is arranged on the processing station, the foam feeding device 2 is arranged on the first side of the processing station, the cavity waste removal device 4 is arranged on the second side or the fourth side of the processing station or arranged on both sides, and the waste collection device 5 is arranged on the waste collection station which is located on the third side of the processing station, i.e. the cavity waste moves along a straight line. By arranging the devices around the processing station, the walking path of each device is reduced, the equipment structure is compact, the occupied space is small, and the operation process is reliable and orderly, thereby improving the production efficiency and saving the production cost.

[0042] Referring to Figures 1 to 3, the foam loading device 2 comprises a material bin 21 for storing the foam tray of the cavity waste to be removed and a pushing mechanism 22 for pushing the foam tray in the material bin 21 to the processing station one by one; the foam tray of the cavity waste to be removed is placed in the material bin 21 in turn, a discharge port 211 is formed between the bottom of the material bin 21 and the workbench 1, and the height dimension of the discharge port 211 is slightly larger than the thickness dimension of one foam tray. The pushing mechanism 22 comprises a pushing plate 221 and a pushing cylinder 222, the pushing cylinder 222 is arranged on the workbench 1 and located at the other side of the discharge port 211 of the material bin 21, and the pushing cylinder 222 is used to drive the pushing plate 221 to slide on the workbench 1 so as to push the foam tray stacked in the material bin 21 from the bottom to the processing station through the discharge port 211 one by one. That is, the pushing plate 221 moves with the table top of the workbench 1, and the thickness dimension of the pushing plate 221 is slightly smaller than the thickness dimension of the foam tray, so that only one foam tray is pushed out each time, and in addition, the foam tray at the upper part of the material bin 21 pressurizes the bottom to ensure the flatness of the foam tray.

[0043] Referring to Figures 2 to 4 , the foam positioning device 3 comprises a limiting piece 31 arranged on the processing station, the limiting piece 31 is connected with the discharge port 211 of the material bin 21, and is used to support the foam tray and position the foam tray on the processing station; the limiting piece 31 comprises a stop plate 311 and a limiting frame 312, the stop plate 311 is arranged on the third side of the processing station, and is used to stop the foam tray sent out from the material bin 21 from continuing to move forward and position the foam tray on the processing station.

[0044] The limiting frame 312 is arranged on the workbench 1 and located between the stop plate 311 and the material bin 21, the limiting frame 312 is a U-shaped frame which is open on the side facing the stop plate 311, a first side of the limiting frame 312 forms a feeding port 3121 with the workbench 1 and the discharge port 211 of the material bin 21, and limiting portions 3122 are arranged on the second side and the fourth side opposite to each other, and the two limiting portions 3122 are two “7”-shaped structures arranged in the radial direction, the two limiting portions 3122 and the table top of the workbench 1 form a guide channel for the foam tray, that is, after the foam tray enters the feeding port 3121 of the limiting frame 312, the second side and the fourth side of the foam tray are stopped by the two side walls of the limiting portions 3122, and the foam tray moves forward along the guide channel until the third side of the foam tray stops moving forward when the third side of the foam tray collides with the stop plate 311, in addition, the horizontal plane of the limiting portions 3122 limits the upper surface edge of the foam tray, and the vertical plane limits the side walls of the first side and the second side of the foam tray, under the cooperation of the limiting frame 312 and the stop plate 311, the upper surface edge of the first side, the second side and the fourth side of the foam tray located on the processing station is positioned, and the side walls of the second side, the third side and the fourth side are positioned, so that when the waste removing mechanism 41 of the cavity waste removing device 4 removes the cavity waste, the position of the foam tray does not change, and the quality of waste removal is ensured.

[0045] Referring to Figure 1 and 5 The cavity waste removal device 4 is arranged on the second side or the fourth side of the machining station, and includes a waste removal mechanism 41, a lifting mechanism 42 for driving the waste removal mechanism 41 to lift or fall, and a translation mechanism 43 for driving the lifting mechanism 42 to drive the waste removal mechanism 41 to move back and forth between the machining station and the waste collection station.

[0046] The waste removal mechanism 41 includes a material insertion needle 411 corresponding to the cavity waste of the foam tray, and a first driving assembly 412 for driving the material insertion needle 411 to move forward and backward, the first driving assembly 412 including a material insertion plate 4121 for mounting the material insertion needle 411, and a first driving cylinder 4122 for driving the material insertion plate 4121 to move forward and backward, the material insertion plate 4121 being horizontally arranged, and the upper end thereof being in transmission connection with the piston rod end of the first driving cylinder 4122 through a connecting piece 4123, and the lower end mounting the material insertion needle 411.

[0047] In addition, the material insertion needle 411 is arranged to be inclined forward and downward from the rear end, i.e. the material insertion needle 411 is arranged at the same interval as the cavity, so that each material insertion needle 411 can be inserted from the center of the waste, and due to the shrinkage property of the foam, when the material insertion needle 411 is inserted, the foam can grip the material insertion needle 411, so as to ensure that the foam will not fall off during the translation.

[0048] In addition, the translation mechanism 43 is arranged on the workbench 1 through a translation support 44, the translation support 44 being located on the second side or the fourth side of the machining station; the translation mechanism 43 including a guide rod 431 arranged horizontally, a guide block 432 in sliding connection with the guide rod 431, and a guide cylinder 433 for driving the guide block 432 to move back and forth on the guide rod 431; the guide rod 431 extending from one side of the machining station to one side of the waste collection station, the guide block 432 being connected with the cylinder body of the second driving cylinder 422 of the lifting mechanism 42 towards the side of the machining station, so as to ensure the smooth movement of the lifting mechanism 42. The translation mechanism 43 can be directly selected from the existing guide rod cylinder.

[0049] The waste removal mechanism 41 is connected to the piston rod end of the second drive cylinder 422 via the connecting block 421. The second drive cylinder 422 drives the waste removal mechanism 41 to descend, causing the insertion needle 411 to directly insert into the cavity waste. The insertion depth can be set by the control device 6. After insertion, the first drive cylinder 4122 pushes the insertion needle 411 forward (i.e., from the second side to the fourth side or from the fourth side to the second side) to separate the cavity waste from the foam tray. Then, the lifting mechanism 42 drives the waste removal mechanism 41 to rise, causing the insertion needle 411 to carry the cavity waste away from the cavity of the foam tray. Then, the translation mechanism 43 drives the insertion needle 411, which picks up the cavity waste, to move from the processing station to the waste collection station. Specifically, since the second or fourth side of the foam tray is stopped by the limiting part 3122 of the limiting frame 312, when the front end of the insert pin 411 moves, the foam tray is restricted and does not move, thereby causing the cavity waste to separate from the cavity along with the insert pin 411.

[0050] See Figures 1 to 3 The waste collection device 5 is located on the third side of the processing station and is installed on the waste collection station. It includes a waste removal stop 51 corresponding to the insert pin 411 and a waste collection box 52 located directly below the waste removal stop 51.

[0051] Specifically, the waste removal stop 51 has a slot 511 that allows the toothed pins 411 picking up cavity waste to slide through. Plate-like members 512 are formed on both sides of the slot 511, i.e., multiple plate-like members 512 are arranged parallel and spaced apart, with the slot 511 formed between them. The width of the slot 511 allows the inclined rows of inserting pins 411 to slide through, and at this time, the cavity waste picked up by the inserting pins 411 is located below the plate-like members 512. Therefore, when the first driving assembly 412 drives the inserting pins 411 to move backward, the plate-like members 512 on both sides of the slot 511 scrape the cavity waste off the toothed pins 411. This embodiment provides a specific structure of the waste removal stop 51, see reference. Figure 6 It has a plate-shaped part of a certain thickness, and a slot is opened on the plate-shaped part with the same tilt angle as the insertion pin. The tilt angle α = 150°. It can be understood that the multiple rows of insertion pins 411 are also tilted at the same angle. This angle setting increases the contact distance between the cavity waste and the insertion pin, while preventing the cavity waste picked up by the insertion pin from falling off during the movement.

[0052] For space considerations, the workbench 1 has a waste discharge port 11 located at the waste collection station. The waste collection box 52 is movably installed at the bottom of the workbench 1 via a bracket 53, so that the waste collection box 52 is located directly below the waste discharge port 11, so that the falling cavity waste material falls directly into the waste collection box 52.

[0053] In this embodiment, two sets of cavity waste removal devices 4 can be provided, respectively arranged on the second and fourth sides of the processing station. The waste removal mechanisms 41 of the two sets of cavity waste removal devices 4 work alternately between the processing station and the waste collection station. That is, when one set of waste removal mechanisms 41 picks up cavity waste at the processing station, the other set scrapes off the waste at the waste collection station, thereby improving production efficiency. Therefore, the specific layout of each device can be adaptively adjusted according to production needs.

[0054] Example 2.

[0055] The difference between this embodiment and Embodiment 1 is that the connecting block 421 of the lifting mechanism 42 has a horizontal surface 4211 and an inclined surface 4212, with the inclined surface 4212 inclined downward from its rear end to its front end.

[0056] Specifically, the cylinder body of the first drive cylinder 4122 of the first drive assembly 412 of the waste removal mechanism 41 is fixedly connected to the inclined surface 4212. Thus, when the first drive cylinder 4122 drives the inserting needle 411 to move back and forth, the inserting needle 411 generates a horizontal component force and an inclined force. Therefore, when the lifting mechanism 42 drives the waste removal mechanism 41 to descend, the front end of the inserting needle 411 can be stopped when it contacts the upper surface of the foam tray. Then, the piston rod of the first drive cylinder 4122 extends to make the inserting needle tilt forward and downward and insert into the waste in the cavity. This increases the contact distance between the waste and the inserting needle, and can separate the waste from the cavity in one step, while ensuring the lifting height and picking accuracy.

[0057] Example 3.

[0058] The difference between this embodiment and embodiment two is that the limiting frame 312 is slidably set on the workbench 1, which is suitable for moving the foam tray with the cavity waste removed away from the processing station. The foam tray falls off the limiting frame 312 from the lower end outlet by its own weight.

[0059] Specifically, a third drive cylinder 32 is provided on one side of the limiting frame 312 parallel to its feed inlet 3121, and the piston rod end of the third drive cylinder 32 is connected to the limiting frame 312 in a transmission manner.

[0060] For collecting foam trays that have completed waste removal, a finished product discharge port can be opened on the workbench, and a finished product collection box can be placed below the finished product discharge port. When the third drive cylinder 32 drives the limiting frame 312 to move directly above the finished product discharge port, its lower outlet is opened, the lower part of the foam tray is unrestricted and falls into the finished product collection box from the finished product discharge port by its own gravity, thus completing the automatic collection of finished products.

[0061] Or such as Figure 2The finished product collecting box 7 is placed on one side of the workbench, the third driving cylinder 32 drives the limiting frame body 312 to move, when the lower end of the limiting frame body 312 is away from the workbench 1, the lower end outlet is opened, and the foam tray falls into the finished product collecting box 7.

[0062] Example four.

[0063] The difference between the embodiment and example three is that the cavity waste removing device 4 is arranged on the third side of the machining station, and the waste collecting device 5 is arranged on the second side or the fourth side of the machining station. On this basis, when the inserting needle 411 of the cavity waste removing device 4 is pushed forward, i.e. pushed from the third side to the first side, since the first side of the limiting frame body 312 is provided with the feeding port 3121, the movable stopper 331 which is slidable relative to the workbench 1 is arranged on one side of the feeding port 3121, so as to prevent the foam tray from moving when the inserting needle 411 is pushed forward. The movable stopper 331 is driven by the fourth driving cylinder 332 to open or close the feeding port 3121.

[0064] That is, after the foam tray in the material bin enters the machining station through the feeding port 3121 along the limiting part 3122, the fourth driving cylinder 332 drives the movable stopper 331 to close the feeding port 3121, so that when the inserting needle 411 is inserted into the cavity waste and inclined towards the first side, the first side of the foam tray is limited by the movable stopper 331, thereby ensuring the stability of the foam tray when the waste is picked up.

[0065] In this embodiment, the side walls of the first side, the second side, the third side and the fourth side of the foam tray on the machining station are all in the limiting state, thereby effectively preventing the movement of the foam tray.

[0066] Taking example four, the operation process of the foam tray cavity waste removing equipment of the present application is as follows:

[0067] In the initial state, the piston rod of the pushing cylinder 222 of the pushing mechanism 22 is retracted, the piston rod of the fourth driving cylinder 332 of the movable stopper mechanism 33 is retracted, the guide block 432 of the translation mechanism 43 is located on one side of the machining station, the piston rod of the second driving cylinder 422 of the lifting mechanism is retracted, the piston rod of the first driving cylinder 4122 of the waste removing mechanism 41 is retracted, and the limiting frame body 312 is located on the machining station and the piston rod of the third driving cylinder 32 is retracted.

[0068] Step one, the foam tray with cavity waste to be removed is fed, the piston rod of the pushing cylinder 222 is extended, one foam tray with cavity waste to be removed located at the bottom of the material bin 21 is pushed out of the discharge port 211 of the material bin 21 by the pushing plate 221, the foam tray enters the machining station through the feeding port 3121 of the limiting frame body 312, and the piston rod of the pushing cylinder 222 is reset.

[0069] Step two, pickup of cavity waste material, the fourth drive cylinder 332 piston rod extends, the movable stopper 331 closes the feed port 211, the second drive cylinder 422 piston rod extends and drives the first drive cylinder 4122 to descend to the contact of the foam tray surface by the material inserting needle 411, the first drive cylinder 4122 piston rod extends and makes the material inserting needle 411 tilt and insert into the cavity waste material of the foam tray, the second drive cylinder 422 piston rod resets, and the pickup of the cavity waste material is completed;

[0070] Synchronously, the piston rod of the third drive cylinder 32 drives the limiting frame to move to the side of the workbench 1, so that the foam tray with the removed cavity waste material falls from the lower outlet of the limiting frame, the piston rod of the third drive cylinder 32 resets, and the fourth drive cylinder 332 piston rod resets to make the stopper 331 open the feed port 211;

[0071] Step three, cavity waste material scraping, the guide cylinder of the translation mechanism 43 drives the guide block 432 to move the material inserting needle 411 with the cavity waste material from the processing station to the waste collection station, and when the material inserting needle 411 stops in the slot 511 of the waste disengaging stopper 51, the first drive cylinder 4122 piston rod retracts, so that the material inserting needle 411 moves backward and upward, so that the cavity waste material is stopped by the sheet-shaped piece 512 on both sides of the slot 511, the cavity waste material scraping is completed, and the guide cylinder drives the guide block 432 to return to the processing station with the empty material inserting needle.

[0072] The processes of steps one to three are opposite, and through the coordinated action of the mechanisms, the automatic removal and collection of the cavity waste material of the foam tray are realized, and the work efficiency is high.

[0073] In summary, the foam tray cavity waste material removal equipment provided by the application sets the limiting piece for positioning the foam tray in the processing station, uses the material inserting needle to tilt forward and downward and insert into the cavity waste material for pickup, and the material characteristics of the foam make it adhere to the material inserting needle, and the lifting mechanism, the translation mechanism and the waste disengaging stopper are used to transfer the cavity waste material from the processing station to the waste collection station and automatically disengage, so that the waste removal action is simple and efficient; the devices are arranged around the processing station, the walking path of each device is reduced, the equipment structure is compact, the occupied space is small, the operation process rhythm is reliable and orderly, so that the production efficiency is improved and the production cost is saved.

[0074] In the foregoing description, numerous specific details are set forth to provide a thorough understanding of the present application. However, there can be cases in which certain implementations of the present application are practicable even though some of the specific details are not disclosed.

It will be apparent to those skilled in the art that many modifications, both to the methods and to the apparatus, can be practiced with the present application without departing from the spirit and the essential characteristics of the present application. Thus, the scope of the present application should be limited only by the appended claims and equivalents thereof.
