Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of folding materials, in particular to a folding material taking and folding device. Background Art

[0002] Convenience foods are very common in people's work and life, such as bucket instant noodles, bucket porridge and other foods, which can make people eat conveniently and quickly when they are busy at work or do not have enough time to eat.

[0003] In the above-mentioned convenience foods, in order to facilitate people's consumption, they are all equipped with tableware, such as forks or spoons. In order to facilitate placement inside the convenience foods, the above-mentioned tableware is a folding structure, thereby reducing the length and size for easy storage.

[0004] Folding tableware is usually made of plastic material through injection molding. During the injection molding process, the tableware with folding structure is usually in an unfolded state, such as Figure 1 In the state shown, some manufacturers currently fold the head and handle of the tableware manually and connect them to each other after removing the tableware from the injection molding machine, such as Figure 2 The folded tableware is then placed inside the convenience food.

DETAILED DESCRIPTION

[0065] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0066] An embodiment of the present utility model provides a folding material picking and folding device, specifically a device for folding tableware such as folding knives, forks, and spoons after they are removed from the injection mold 510 of the injection molding machine 500 after the injection molding process is completed. The device can automatically cooperate with the injection mold 510 to remove the injection-molded material from the mold 510, fold the material in an unfolded state through the folding device 200, and then transport the folded material to the packaging box transported by the conveying device 400.

[0067] like Figure 3-15 As shown, the embodiment of the present invention is a folding material taking and folding device, which is used to fold two parts of material with movable connection. In this embodiment, the folding material is exemplified by a folding fork, such as Figure 1-2 As shown, Figure 1 After the injection molding process is completed, the fork is in an unfolded state. The device provided in this embodiment will be as follows Figure 1 The fork shown is removed from the injection molding machine 500 and folded so that the head 10 and the handle 20 of the fork are folded together to form a shape as shown in FIG. Figure 2 The state shown is shown, and it is transferred to the packaging box transported by the conveying device 400 to complete the packing. The folding material picking and folding equipment provided in this embodiment includes a picking device 100, a folding device 200, a feeding device 300 and a conveying device 400, wherein the picking device 100 is used to grab the folding material, which includes a suction cup assembly 110 provided with a plurality of suction nozzles 101, and also includes a linear module 102 that is connected to the suction cup assembly 110 and drives the suction cup assembly 110 to move back and forth along a first predetermined direction; a plate 201 is provided on the travel path of the suction cup assembly 110, and a toggle assembly 210 and a pressing assembly 220 are provided on the plate 201. , wherein the shifting component 210 is used to shift one part of the material toward another part, and the pressing component 220 is used to press two adjacent parts of the material together; the unloading device 300 is arranged beside the folding device 200 along the moving direction of the device, including a bottom plate 301 corresponding to the suction cup component 110, and a mounting cavity 302 that is shaped like the shape of the material is formed on the bottom plate 301, and a clamping component 310 for clamping the material in the mounting cavity 302 is also provided on the bottom plate 301; the conveying device 400 is arranged below the unloading device 300, and includes a conveyor belt arranged along the second predetermined direction, which is used to receive the material for unloading and transfer, and convey the material along the predetermined direction.

[0068] When the folding fork is in the process of taking up and folding the material, the suction cup assembly 110 is driven and transported by the linear module 102, thereby moving toward the injection mold 510. In this embodiment, the first predetermined direction in which the linear module 102 drives the suction cup assembly 110 is toward the injection molding machine 500, thereby moving the suction cup module toward the injection mold 510, so that the suction cup assembly 110 and the injection mold 510 are docked with each other, and the suction nozzle 101 sucks the folding fork located on the injection mold 510; then it is driven back by the linear module 102, thereby moving to the position of the folding device 200, and docking the suction cup assembly 110 with the plate 201 of the folding device 200, so that the toggle assembly 210 folds the handle 20 of the fork toward the head 10. The pressing group will press the folded handle 20 toward the head 10, so that the head 10 and the handle 20 are engaged with each other to complete the folding action; the linear module 102 will move the folded fork toward the blanking device 300, so that the folded fork is installed in the installation cavity 302 on the base plate 301, and the fork located in the installation cavity 302 is clamped and fixed by the clamping assembly 310, so that the blanking assembly can transfer the fork to the conveying device 400. Specifically, the conveying device 400 is provided with a conveyor belt arranged along a second predetermined direction for transporting and conveying packaging boxes. The blanking device 300 transfers the fork located in the installation cavity 302 into the packaging box, and the packaging box is transported to the next processing step by the conveyor belt along the second predetermined direction.

[0069] Through the technical solution provided by this embodiment, the suction cup assembly 110 is driven by the linear module 102 to move toward the injection molding machine 500, thereby picking up the folding fork that has been injection molded, and the handle 20 of the folding fork is moved toward the head 10 by the toggle assembly 210, and under the action of the pressing assembly 220, the handle 20 folded toward the head 10 is pressed toward the head 10, so that the handle 20 is clamped on the head 10, completing the folding process of the folding fork, and then the unloading device 300 removes the folded fork from the suction cup assembly 110 of the picking device 100 and transfers it to the packaging box transported by the conveyor belt, completing the unloading of the fork. Through this technical solution, the fork that has been completed by injection molding can be automatically picked up, folded, and unloaded and transported, which can greatly reduce the participation of operators in the entire processing link, reduce the labor intensity of operators, and improve the efficiency of production and processing.

[0070] like Figure 4-7As shown, in this embodiment, an example of the specific structure of the material picking device 100 is given. The material picking device 100 also includes a base 103, which is transmission-connected to the linear module 102 and driven by the linear module 102 to reciprocate along a first predetermined direction. A suspension beam 104 extending in the moving direction is provided on the base 103. The suction cup assembly 110 is mounted on the suspension beam 104. The suction cup assembly 110 is supported by the base 103 and the suspension beam 104, so that the suction cup assembly 110 has the ability to extend toward the injection molding machine 500. The suspension beam 104 can also play a role in avoiding interference with components on the injection molding machine 500. Figure 5-7 As shown. The suction cup assembly 110 includes a mounting plate 111, a first mounting seat 112, a second mounting seat 114 and a positioning rod 116, wherein the mounting plate 111 is mounted on the suspension beam 104; the first mounting seat 112 includes a plurality of mounting seats fixedly mounted on the mounting plate 111, and a plurality of first mounting grooves 113 arranged side by side are provided on the first mounting seat 112; the second mounting seat 114 includes a plurality of mounting seats corresponding to the first mounting seats 112 and respectively opposite to the first mounting seats 112, and a second mounting groove 115 corresponding to the first mounting groove 113 is provided on the second mounting seat 114; the suction nozzle 101 includes a plurality of mounting seats corresponding to the first mounting groove 113 and the second mounting groove 115, and is respectively arranged between the corresponding first mounting grooves 113 and second mounting grooves 115.

[0071] That is to say, the first mounting seat 112 and the second mounting seat 114 are arranged side by side with each other, and the first mounting seat 112 and the second mounting seat 114 are provided with a first mounting groove 113 and a second mounting groove 115 corresponding to each other, wherein in the process of sucking the fork. The first mounting groove 113 and the second mounting groove 115 are respectively used to accommodate the two end positions of the fork head 10, and the handle 20 of the fork is suspended, so as to facilitate the folding of the handle 20 toward the head 10. At this time, since the suction nozzle 101 is located between the first mounting groove 113 and the second mounting groove 115, the head 10 can be adsorbed, so that the folding fork can be stably adsorbed within the first mounting groove 113 and the second mounting groove 115. It can be understood that the head 10 of the fork has a relatively flat and large area. The part is located in the middle position of the fork head 10, so that the suction nozzle 101 is set between the first mounting groove 113 and the second mounting groove 115, so that the part of the fork can be adsorbed, ensuring a stable and reliable adsorption force. Figure 5-7As can be seen, multiple first mounting slots 113 and second mounting slots 115 are provided side by side, allowing multiple forks to be used for suction at once. To ensure accuracy during alignment with the injection mold 510, a plurality of positioning rods 116 are provided on the mounting plate 111 to correspond to positioning holes on the injection mold 510. When the positioning rods 116 are inserted into the positioning holes, the suction nozzle 101 can be accurately aligned with the forks on the injection mold 510.

[0072] In this embodiment, the suction cup assembly 110 is transported by the linear module 102 toward the injection molding machine 500 and when it is in a position corresponding to the injection mold 510, the suspension beam 104 drives the suction cup assembly 110 to move toward the injection mold 510, thereby enabling the suction cup assembly 110 and the injection mold 510 to dock with each other. Specifically, Figure 4 As shown, the suspension beam 104 is slidably connected to the base 103, and a first driving unit 105 is also provided on the base 103 to drive the suspension beam 104 to reciprocate along the plane of the base 103. In this embodiment, the first driving unit 105 is implemented as a motor, which drives the suspension beam 104 to move on the base 103 via a synchronous belt, thereby enabling the suction cup assembly 110 to move toward the injection mold 510.

[0073] In a further improvement, in order to further improve the stability of the docking between the suction cup assembly 110 and the injection mold 510, a first driving cylinder 118 is provided on the suspension beam 104. After the suction cup assembly 110 approaches the injection mold 510, it can move toward the injection mold 510 at a slower speed, thereby docking with the injection mold 510 and ensuring better precision. Figure 6 As shown, a mounting frame 117 is fixedly installed on the mounting plate 111, and the mounting frame 117 is slidably connected to the suspension beam 104 along the moving direction of the suspension beam 104, and a first driving cylinder 118 is fixedly installed on the suspension beam 104 and is transmission-connected to the mounting frame 117. The first driving cylinder 118 drives the mounting frame 117 and the mounting plate 111 to move back and forth.

[0074] The suction cup assembly 110 can ensure movement efficiency through the two-stage movement of the first drive unit 105 and the first drive cylinder 118. At the same time, the suction cup assembly 110 can be slowly moved toward the injection mold 510 through the slow drive of the first drive cylinder 118, thereby avoiding the shaking of the suction cup assembly 110 during the movement, thereby improving the accuracy of docking with the injection mold 510.

[0075] In this embodiment, the shifting assembly 210 of the folding device 200 is used to fold a portion of the folding material (i.e., the folding fork) removed by the material taking device 100 toward another portion. In this embodiment, the handle 20 of the fork is shifted toward the head 10, so that the handle 20 and the head 10 are close to each other. In this embodiment, Figure 8-9 As shown, the toggle assembly 210 includes a connecting rod 211, a push rod 212 and a second driving cylinder 213, wherein the connecting rod is slidably connected to the plate along the direction parallel to the first mounting groove 113 and the second connecting groove; the push rod 212 is arranged along the direction parallel to the first mounting groove 113, and is fixedly connected to the connecting rod 211 through an intermediate piece; the second driving cylinder 213 is fixedly connected to the plate and is transmission-connected to the connecting rod 211, so as to drive the push rod 212 to move back and forth toward or away from the first mounting groove 113 and the second mounting groove 115.

[0076] When the fork on the material taking device 100 is folded, the fork is in the following shape after injection molding by the injection molding machine 500. Figure 1 Therefore, after the fork is adsorbed in the installation groove, it is as follows Figure 7 In the state shown, the push rods 212 are arranged side by side along the first mounting grooves 113. In this embodiment, the first mounting grooves 113 are arranged side by side in the vertical direction, that is, after the forks are adsorbed on the mounting plate 111, they are arranged side by side in the vertical direction. Driven by the second driving cylinder 213, the push rods 212 move from the first mounting groove 113 toward the second mounting groove 115, thereby moving the handle 20 of the fork toward the head 10 to complete the folding of the fork.

[0077] In this embodiment, several groups of first mounting seats 112 and second mounting seats 114 are provided, and are installed side by side on the mounting plate 111. In order to ensure the overall stability of the equipment during the folding process of the spoon, the first mounting seats 112 and the second mounting seats 114 located on the left and right parts of the mounting plate 111 are symmetrically arranged along the center line. That is to say, the mounting seats at the left and right sides of the displacement mounting plate 111 are both positioned in the first mounting grooves 113, so that the handles 20 of the forks located at the edges of both sides of the mounting plate 111 are both facing the outside of the mounting plate 111. At this time, the toggle assembly 210 is provided with two groups side by side, and the moving directions of the connecting rods 211 of the two toggle assemblies 210 are set in opposite directions. When the fork needs to be folded, the two sets of toggle assemblies 210 need to be toggled from the outside of the mounting plate 111 toward the inside, so that the handle 20 extending toward the outside of the mounting plate 111 is folded toward the head 10. The toggle directions of the two sets of toggle assemblies 210 are opposite, so as to reduce the toggle forces generated by the toggle action of the toggle assemblies 210 from offsetting each other, and reduce the vibration caused by the toggle assemblies 210 being toggled in the same direction, which affects the accuracy of the fork toggle.

[0078] In this embodiment, the pressing assembly 220 is used to press the handle 20 folded toward the head 10 so that the head 10 and the handle 20 can be connected to each other to form a Figure 2 The stable folded state shown, Figure 9-10 As shown, the pressing assembly 220 includes: a third driving cylinder 221, a pressing plate 222 and a pressing cylinder 223. Specifically, the third driving cylinder 221 is fixedly installed on the plate 201, and the extension direction of the piston rod of the third driving cylinder 221 is perpendicular to the plate 201; the pressing plate 222 is fixedly connected to the piston rod of the third driving cylinder 221, and is driven to move back and forth by it; the pressing cylinder 223 includes a plurality of corresponding to the second mounting groove 115, and is fixedly arranged on the pressing plate 222, and the pressing cylinder 223 is transmission-connected to the pressing block 224 for pressing the two parts of the material together.

[0079] That is, the third driving cylinder 221 rapidly drives the pressing plate 222 toward the material-retrieving device 100. As they approach each other, the pressing cylinder 223 is activated to move the pressing block 224 toward the fork handle 20, thereby pressing the handle 20 onto the head 10. It is understood that the pressing cylinder 223 and the third driving cylinder 221 have different driving forces, and the driving force of the pressing cylinder 223 is smaller than that of the third cylinder. During the pressing process, the piston rod of the pressing cylinder 223 extends at a lower speed, thereby preventing damage to the fork due to excessive movement.

[0080] Since the handle 20 of the fork needs to be pressed toward the head 10, a driving force is indirectly applied to the driving device. In order to avoid that during the pressing process of the handle 20, the suction cup assembly 110 will not be pushed away from the folding device 200 by the pressing cylinder 223, thereby affecting the mutual card box between the handle 20 and the head 10, Figure 9 As shown, a tightening unit is also provided on the toggle assembly 210. The tightening unit 214 includes two corresponding to the toggle assembly 210, and is respectively arranged on both sides of the plate 201. The tightening unit 214 includes a clamping frame 2141 and a tightening arm 2142.
