[0003] Congee is a kind of food that often appears in people's lives. Congee is stored in a can and a spoon is provided on the can for people to use. Figure 1-2 As shown, in order to facilitate the attachment of the spoon to the can, the spoon is usually provided with a folding structure, so that the length of the spoon can be shortened and conveniently attached to the can.

[0004] In order to make the spoon convenient to use and able to be clamped at the end of the can, the spoon is usually provided with three mutually rotatably connected parts, such as Figure 1-2 As shown, the folding spoon has a handle, a stem and a spoon that are rotatably connected to each other. When folding, the handle is folded toward the stem first, and then the spoon is folded toward the stem, so that the three parts are folded to reduce the overall length. The folding spoon is made of plastic material through injection molding. During the injection molding process, the folding spoon is usually in an unfolded state, as shown in FIG. Figure 1 In the state shown, some manufacturers currently fold and connect the tableware manually after removing the tableware from the injection molding machine, such as Figure 2 The folded spoon is then placed inside the instant food, i.e., on the end of the instant porridge jar.

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] The embodiment of the utility model provides a double-fold material picking and folding device, which can be used to pick up materials with three movable parts on the injection molding machine 04, and fold the three movable parts and then perform blanking processing. In this embodiment, a folding spoon is used as a specific processing object, such as Figure 1-2 As shown, the folding spoon includes a handle 01, a rod 02 and a spoon 03 that are movably connected in sequence. During the folding process, the handle 01 of the spoon is first folded toward the rod 02, and then the spoon 03 of the spoon is folded toward the folded handle 01, so that the spoon 03 is folded and the folded handle 01 is buckled into the spoon 03.

[0067] like Figure 3-17As shown, the embodiment of the present invention provides a double-fold material picking and folding device, which folds materials with three parts that have been movably connected, and includes a picking device 100 for grabbing materials and a unloading device 200 for transferring and unloading materials after folding. It is characterized in that it also includes a folding device 300 arranged between the picking device 100 and the unloading device 200 for folding the materials, and the folding device 300 includes: a mounting plate 301, a first toggle assembly 310, a second toggle assembly 320 and a pressing assembly 331, wherein the mounting plate 301 is arranged on the frame 06, and the first toggle assembly 310 includes a sliding connection on the mounting plate 301 The toggle block 311 above it and the first driving cylinder 312 that drives the toggle block 311 to move back and forth in a straight line; the second toggle assembly 320 and the first toggle assembly 310 are arranged side by side on the mounting plate 301, and the second toggle assembly 320 includes a toggle rod 321 slidably connected to the mounting plate 301 along the sliding direction of the toggle block 311, and also includes a second toggle cylinder 322 that drives the toggle rod 321 to move back and forth in a straight line; the pressing assembly 331 is arranged between the first toggle assembly 310 and the second toggle assembly, which includes a pressing cylinder fixedly mounted on the mounting plate 301 and a pressing block 332 that is transmission-connected to the pressing cylinder and extends or retracts in a direction perpendicular to the mounting plate 301.

[0068] The material taking device 100 takes the injection molded material off the injection mold 05 of the injection molding machine 04 and transfers it to the folding device 300 for folding. During the folding process, the first toggle component 310 folds the handle 01 toward the rod 02, and then the second toggle component 320 folds the spoon 03. Finally, the pressing component 331 presses the folded material toward the rod 02, so that the clamping mechanisms located on the rod 02 and the spoon 03 are clamped with each other, thereby completing the folding process of the spoon. Specifically, the toggle block 311 is driven by the first driving cylinder to move, so that the raised handle 01 is pushed by the toggle block 311 to be folded toward the rod 02. After the handle 01 and the rod 02 are overlapped with each other, the toggle rod 321 is driven by the second toggle cylinder 322 to move toward the toggle block 311, so that the raised spoon 03 can be moved toward the folded handle 01, thereby folding the spoon 03 and placing the folded handle 01 into the spoon 03. Finally, the pressing assembly 331 located between the first toggle assembly 310 and the second toggle assembly 320 presses the folded spoon 03 toward the rod 02. Specifically, the pressing cylinder pushes the pressing block 332 to move toward the rod 02, thereby pressing the spoon 03 on the rod 02, so that the corresponding clamping mechanisms on the rod 02 and the spoon 03 engage with each other, thereby realizing the folding process of the spoon.

[0069] In the folding device provided in this embodiment, the movable portions at both ends of the spoon can be folded toward the middle portion through two toggle assemblies, that is, the handle 01 and the spoon portion 03 of the spoon can be folded toward the stem 02. The spoon portion 03 can be mutually engaged with the stem 02 through the pressing assembly 331, so that the handle 01 can be accommodated within the spoon portion 03 after the spoon portion 03 is folded. The overall structure is more concise, the volume is reduced, and the assembly of the spoon and the packaging can is convenient. The folding device provided in this embodiment of the utility model greatly reduces the operator's involvement in the spoon folding process, reduces the operator's labor intensity, and improves production efficiency.

[0070] In this embodiment, the toggle block 311 comprises a first sliding member 3111 and a toggle member 3112. The first sliding member 3111 is slidably connected to the mounting plate 301 and is in transmission connection with the first driving cylinder. The toggle member 3112 is fixedly mounted on the first sliding member 3111, and the corners of the toggle member 3112 facing the second toggle assembly 320 are provided with arc chamfers. The arc chamfers allow for smoother toggle movement of the handle 01 without causing any scratches or damage to the handle 01. In this embodiment, the sliding member is an elongated structure, with a first driving cylinder provided at each end to drive it. To improve efficiency, multiple toggle members 3112 are provided on the first sliding member 3111, allowing simultaneous toggle and folding of multiple spoons.

[0071] At the same time, in order to make the handle 01 more stable when folded onto the rod 02, a mutually clamping mechanism is also provided on the handle 01 and the rod 02, so that the handle 01 can be stably folded onto the rod 02, so that the folded handle 01 and the rod 02 can be clamped to each other. Figure 13-14 As shown, a linkage hole 3113 is provided on the toggle member 3112, and the toggle member 3112 is also provided with: a pressure rod 3114, an elastic member 3115 and a pressure cylinder 3116, wherein the pressure rod 3114 is slidably connected in the linkage hole 3113, and one end extends toward the outside of the linkage hole 3113, and the other end slides within the linkage hole 3113 with a limited position; the elastic member 3115 is arranged in the linkage hole 3113 and is sleeved on the pressure rod 3114, so as to provide an elastic force to the pressure rod 3114 toward the bottom of the linkage hole 3113; the pressure cylinder 3116 is fixedly mounted on the toggle member 3112, and is transmission-connected to the pressure rod 3114, so as to drive the pressure rod 3114 to overcome the elastic force and extend toward the outside of the linkage hole 3113.

[0072] That is, in the initial state, the pressing rod 3114 is retracted within the linkage hole 3113 under the elastic force of the elastic member 3115, so that the handle 01 is not affected during the process of the toggle block 311 to toggle the handle 01. During the process of toggling the handle 01 to dock with the rod 02, the pressing cylinder 3116 drives the pressing rod 3114, so that it can overcome the elastic force and then extend the linkage rod, thereby pressing the folded handle 01 and thus engaging the handle 01 and the rod 02. Finally, the toggle block 311 can be retracted under the drive of the first driving cylinder 312 to avoid interference with subsequent actions, especially to avoid interference with the pressing action of the pressing assembly 331 to press the spoon 03.

[0073] In the embodiment of the present invention, the toggle lever 321 further includes a second sliding member 3211 and a rod 3212. The second sliding member 3211 is slidably connected to the mounting plate 301 and is in transmission connection with the second toggle cylinder 322. The rod 3212 is fixedly mounted on the second sliding member 3211 and reciprocates with the second sliding member 3211. In this embodiment, the sliding member can be provided in multiple sections. The rod 3212 is a long strip-shaped member that is simultaneously connected to the multiple sections of the second sliding member 3211. This allows the rod 3212 to move more stably when the second toggle cylinder 322 drives the second sliding member 3211 to move.

[0074] In this embodiment, the pressing assembly 331 includes a linkage rod, a linkage plate 333 is connected to the pressing cylinder, and a pressing block 332 is arranged on the linkage plate 333. Figure 12 A plurality of pressing blocks 332 arranged side by side can be provided on the linkage rod. When the pressing cylinder drives the linkage plate 333, the plurality of pressing blocks 332 can be driven to move simultaneously, thereby pressing the plurality of spoon portions 03 and improving the overall folding efficiency.

[0075] At the same time, in order to avoid excessive pressure on the spoon part 03 during the pressing process to avoid damage to the spoon part 03, as shown in FIG. Figure 12As shown, a pressing cylinder 334 is fixedly provided on the linkage plate 333. The pressing cylinder 334 is in transmission connection with the pressing block 332 to drive the pressing block 332 to move back and forth. During the process of pressing the spoon portion 03, the pressing cylinder moves the linkage plate 333 in advance toward the folding direction of the spoon. When approaching the spoon portion 03, the pressing cylinder 3116 drives the pressing block 332 to move slowly to press the spoon portion 03, thereby engaging and connecting the spoon portion 03 with the rod portion 02, completing the folding action of the spoon. The addition of the pressing cylinder 334 can prevent the pressing block 332 from applying excessive pressure on the spoon portion 03, thereby preventing the pressing block 332 from being damaged. It can be imagined that the driving speed and driving force of the pressing cylinder 334 are less than the driving speed and driving force of the pressing cylinder.

[0076] like Figure 18-22 The figure shows a flow chart of folding the spoon by the material picking and folding device provided in this embodiment. The working process of folding the spoon is as follows: in the first step, the mounting frame 110 of the material picking device 100 drives the spoon in the open state to move toward the folding device 300; in the second step, the corner cylinder 302 on the folding device 300 is actuated to clamp the mounting frame 110 to prevent the mounting frame 100 from being pushed away from the folding device during the folding of the spoon. It should be noted that the corner cylinder 302 is arranged at the edge of the mounting plate 301; in the third step, the toggle member 3112 moves toward the handle 01 of the spoon, thereby folding the handle 01 toward the rod 02; in the fourth step, the pressing rod 3114 located on the toggle member 3112 extends toward the handle 01 under the drive of the pressing cylinder 3116, thereby pressing the handle 01 The handle 01 and the rod 02 are tightly connected; in the fifth and sixth steps, the pressing rod 3114 is retracted upward, and the toggle member 3112 is retracted; in the seventh step, the rod 3212 moves toward the spoon 03, thereby pushing the spoon 03 to fold toward the rod 02; in the eighth step, the rod 3212 does not retract, and the pressing assembly 330 moves toward the spoon 03 to press the spoon 03 against the rod 02. Specifically, the pressing cylinder 331 drives the pressing block 332 to move toward the spoon portion 03, thereby pressing the spoon portion 03 against the rod portion 02, so that the spoon portion 03 and the rod portion 02 are engaged with each other; in steps 9 and 10, the rod 3212 and the pressing assembly 330 withdraw, and the corner cylinder 302 releases the mounting bracket 110, so that the mounting bracket 110 drives the folded spoon and the folding device to separate from each other, completing the folding operation of the spoon.

[0077] Example 1

[0078] In this embodiment, the structure of the material taking device 100 is given as an example, and the folding structure is the same as described above.

[0079] like Figure 4-7 As shown, the picking device 100 is used to grab the folding material from the injection mold 05 of the injection molding machine 04 and transport it toward the folding device 300 and the unloading device 200. It includes a linear module 101, a mounting frame 110, and a picking block 111, wherein the linear module 101 is arranged side by side along the folding device 300 and the unloading device 200; the mounting frame 110 is arranged on the linear module 101 and is driven by the linear module 101 to move back and forth along a straight line; the picking block 111 is fixedly mounted on the mounting frame 110, and a receiving groove 112 is arranged on the picking block 111 in the shape of the material, and a suction nozzle 113 is arranged in the receiving groove 112. The linear module 101 drives the mounting parts to move back and forth between the injection molding machine 04, the folding device 300 and the unloading device 200, thereby completing the work of picking up, folding and unloading the materials. In the process of sucking the materials, a receiving groove 112 is provided on the picking block 111. After the mounting frame 110 and the injection mold 05 are docked with each other, the material is embedded in the receiving groove 112 and is sucked and fixed by a suction nozzle 113, thereby adsorbing the material in the receiving groove 112.

[0080] At the same time, in order to enable more precise docking with the injection mold 05, the folding device 300 and the blanking device 200, a base body 120, a suspension beam 121 and an intermediate plate 123 are also provided on the picking device 100. Specifically, the base body 120 is installed on the linear module 101 and is driven by it to move back and forth in a linear direction; the suspension beam 121 is slidably connected to the base body 120, and a first driving unit 122 is also provided on the base body 120 to drive the suspension beam 121 to move back and forth along the plane of the base body 120; the mounting plate 301 is fixedly connected to the intermediate plate 123, and the intermediate plate 123 is slidably connected to the suspension beam 121 along the moving direction of the suspension beam 121, and a second driving cylinder 124 that is transmission-connected to the mounting frame 110 is fixedly installed on the suspension beam 121, and the second driving cylinder 124 drives the mounting frame 110 and the mounting plate 301 to move back and forth.

[0081] The first driving unit 122 drives the suspension beam 121, so that the mounting frame 110 can move quickly toward the injection mold 05, the folding device 300 or the blanking device 200. After approaching each other, the second driving cylinder 124 drives the middle plate 123 to slowly drive the mounting frame 110 to move, so that the material removal block 111 on the mounting frame 110 can be slowly docked with the injection mold 05, the folding device 300 or the blanking device 200, thereby improving the accuracy of the docking.

[0082] Example 2

[0083] In this embodiment, the specific structure of the material unloading device 200 is given as an example, and the material taking device 100 and the material unloading device 200 are the same as those described above.

[0084] like Figure 15-17 As shown, the unloading device 200 includes an X-axis moving component 201, a connecting rod 203 and a unloading tray, wherein the X-axis moving component 201 is set in the same moving direction as the linear module 101, and is connected to a base plate 202 for transmission; the connecting rod 203 is slidably connected to the base plate 202 in the vertical direction, and a driving motor 204 that is transmission-connected to the connecting rod 203 is also installed on the base plate 202, and a right-angle flipping mechanism 210 is installed on the connecting rod 203; the unloading tray is fixedly installed on the right-angle flipping mechanism 210, and a suction cup is provided on the unloading tray.

[0085] In this embodiment, the X-axis moving component 201 is hoisted on the top of the frame 06, so that the connecting rod 203 is suspended and arranged in the vertical direction. Under the drive of the drive motor 204, it can move back and forth in the vertical direction on the base plate 202, thereby driving the unloading tray to move back and forth up and down. The unloading tray is flipped under the drive of the right-angle flipping mechanism 210, so that it can be docked with the material picking device 100 to grab the folded material in the receiving groove 112, and after grabbing the material, flip it again and flip it toward the conveying device or storage device to unload the material.

[0086] like Figure 17 As shown, the right-angle flipping mechanism 210 can flip the mounting plate 301 at a right angle, thereby transferring the mounting plate 301 between the material picking device 100 and the conveying device or the storage device. Specifically, the right-angle flipping mechanism 210 includes a flipping drive cylinder 211 and a flipping plate 213, wherein the flipping drive cylinder 211 is fixedly mounted on the connecting rod 203, and the flipping drive cylinder 211 is connected to a rack 212 for transmission and drives the rack 212 to move back and forth; one end face of the flipping plate 213 supports a connecting ear 214 that is rotatably connected to the flipping drive cylinder 211, and is also formed with a connecting block 215, on which teeth that mesh with the rack 212 are provided, and the unloading tray is fixedly mounted on the flipping plate 213. The rack 212 and the connecting block 215 are engaged with the teeth to transmit the power, so that the flip plate 213 can be driven to flip.
