Description

Technical Field

[0001] This utility model relates to the field of hinge packing technology, and in particular to an automatic packing device for hinge products. Background Technology

[0002] A hinge is a mechanical device used to connect two relatively independent solids and allow them to rotate relative to each other. Hinges are very common furniture door connectors, utilizing the principle of movable hinges to allow the door to open or close around a pivot. A hinge is mainly assembled from components such as a hinge cup, four-hole bracket, arm, base, U-shaped nail, inner strip assembly, torsion spring, plastic tube, and several rivets and screws. The main body of a hinge is generally made of iron or stainless steel. The hinge is generally T-shaped, and the edges of the hinge cup and base are relatively sharp, making them prone to scratches during handling.

[0003] With the development of technology, robotic automated packaging technology has gradually expanded to various industrial fields. In the hardware industry, the reliability, efficiency, and operability of automated devices are steadily improving. Currently, manual packing is still widely used in hinge production. Manual packing is inefficient, and the quality is greatly affected by the operator, easily leading to omissions. Workers are also susceptible to cuts from the sharp edges of the hinges, negatively impacting their health. Against this backdrop, researching and developing low-cost automated packing devices and technologies for hinge products is of great significance for improving hinge production efficiency, quality, and enterprise competitiveness.

[0004] In the packaging process of hinges, the existing technology generally involves first sealing the hinges in bags and then placing them into a packaging box. The above-mentioned packaging method also requires placing the hinge packaging bags into the packaging box's packing device, thereby further improving production efficiency. For example, the Chinese utility model patent with publication number CN222663849U disclosed by the applicant is "An Automatic Packing Device for Hinges with Suction Cups". This patent uses a buffer suction cup assembly to reduce the pressure on the hinges during the material handling process, avoid wear on the hinges during the material handling process, and make the hinges in the packaging box neatly and horizontally arranged. It controls the positional relationship between the top block and the vacuum suction cup, so that the buffer suction cup assembly can not only attract the hinges but also smoothly pick up and put the hinges in, thereby improving packaging efficiency and reducing damage caused by mutual collisions during packaging. Furthermore, the Chinese utility model patent application with publication number CN222496746U disclosed "An Automatic Packing Device for Magnetic Hinges". This patent uses an electromagnetic adsorption component to arrange the hinges in the packaging box neatly and horizontally. The sensing component can detect in real time whether the hinges in the loading tray have been removed, and control the magnetic adsorption state of the electromagnetic chuck to attract the hinges and the non-magnetic adsorption state to release the hinges. This allows the electromagnetic chuck to not only attract the hinges but also to smoothly pick up and put the materials from the hinges, thereby improving packaging efficiency and reducing damage caused by mutual collisions during packaging.

[0005] However, both of the above methods increase the space occupied by the air left in the packaging bags, and the hinges of the packaging boxes are prone to shaking during transportation. In addition, the packaging boxes need to be moved during the packing process to accommodate the stacking of packaging bags. In both processes, the packaging bags are prone to scratching each other. Since the edges of the hinges are relatively sharp, they can easily cause damage to the packaging bags. At the same time, since the hinges are attached by suction cups or magnets during the packing process, there is a small probability of instability, which can cause the hinges to fall off during the packing process. This results in a shortage of hinges in the packaging boxes, and the number of hinges in the boxes needs to be manually checked again after packing is completed, which affects production efficiency.

[0006] Therefore, it is necessary to design a device that can directly pack hinge products into boxes, based on the shape characteristics of the hinge products and the size of the packaging boxes. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide an automatic packing device for hinge products and its working method.

[0008] To solve the above-mentioned technical problems, this utility model provides an automatic packing device for hinge products, including a material feeding and conveying mechanism, a material dispensing mechanism and a box feeding mechanism. The material dispensing mechanism is disposed on one side of the material feeding and conveying mechanism, and the box feeding mechanism is disposed below the material dispensing mechanism.

[0009] The rotating feeding assembly of the feeding mechanism includes a support plate and a baffle. The support plate is inclined, with a feed port on the high side for the hinge to enter and a discharge port on the low side for the hinge to slide out. The baffle is fixedly mounted on the support plate to block the discharge port. The material conveying mechanism pushes the hinges onto the support plate in a preset arrangement. The support plate descends into the packaging box of the box conveying mechanism. The support plate slides upward to expose the discharge port, and the hinge slides from the discharge port into the packaging box on the box conveying mechanism.

[0010] In a further embodiment, the carrier tray alternately and repeatedly descends into the packaging box of the box delivery mechanism while facing either the first or the second direction.

[0011] In a further embodiment, the material handling and transfer mechanism includes a rotating material handling gripper, which includes a rotating component and a clamping component disposed on the rotating component. The clamping component is used to clamp the hinge, and then the rotating component drives the clamping component to alternately rotate the hinge 180°.

[0012] In a further embodiment, the material handling and transfer mechanism further includes a material transfer assembly, which includes a material slide rail, a material support bar slidably disposed on the material slide rail, and a pushing component. The hinges gripped by the rotating material handling gripper are arranged laterally on the material support bar, and the pushing component pushes the hinges on the material support bar so that adjacent hinges overlap each other.

[0013] In a further embodiment, the material support strip has a raised center, forming an inverted "V" shape.

[0014] In a further embodiment, the material handling and transfer mechanism further includes a transfer component. When the hinges on the material waiting bar reach a preset number, the material waiting bar slides along the material waiting rail onto the transfer component. The blocking component of the transfer component blocks the hinges, and the material waiting bar is pulled out so that the hinges remain on the output material waiting plate of the transfer component. The transfer component includes a pushing component, which pushes the hinges on the output material waiting plate onto the rotary feeding component.

[0015] In a further embodiment, the material handling and transfer mechanism also includes a conveyor line that carries the hinge.

[0016] In a further embodiment, the rotary feeding assembly also includes a rotating shaft and a frame, wherein the frame is rotatably mounted on the rotating shaft, and the bearing plate is vertically mounted on the frame.

[0017] In a further embodiment, the feeding mechanism further includes a lifting assembly, and the rotary feeding assembly is disposed on the lifting assembly. The lifting assembly includes a sliding component and a lifting slide rail. The lifting slide rail is fixedly disposed above the box feeding mechanism, and the rotary feeding assembly is slidably disposed on the lifting slide rail via the sliding component.

[0018] In a further embodiment, the box feeding mechanism also includes a first box conveyor line and a second box conveyor line, wherein the output end of the first box conveyor line is adjacent to the input end of the second box conveyor line;

[0019] A positioning component is provided on the first packaging box conveyor line. The positioning component includes a support platform and four positioning plates disposed on both sides of the first packaging box conveyor line. The positioning plates are telescopically disposed on the support platform. The positioning plates are "L" shaped. The four positioning plates extend simultaneously to clamp the four opposite corners of the packaging box and position the packaging box.

[0020] The first packaging box conveyor line output end is provided with a box pushing assembly. The box pushing assembly includes a support component, a box pushing slide rail, and a pushing elastic element fixedly disposed on the box pushing slide rail. The box pushing slide rail is slidably disposed on the support component. The box pushing slide rail and the support component are slidably engaged, so that the pushing elastic element pushes the packaging box on the first packaging box conveyor line to the second packaging box conveyor line.

[0021] Implementing this utility model has the following beneficial effects:

[0022] This invention changes the traditional method of transferring and packing arranged hinges using external force such as suction cups or magnets. Instead, it uses the product's own weight to complete the packing, avoiding the loss of individual products due to different product specifications or insufficient suction. It is also suitable for products of different sizes. The inclined carrier tray can use the weight of the hinges to place them stably into the packaging box. The height difference between the loading height of the carrier tray and the height of the hinges in the packaging box is controlled at 3mm-4mm each time, which can reduce the damage caused by the hinges colliding with each other when entering the box.

[0023] The rotating feeding component and the positioning component work together. After the carrier plate receives the hinge pushed by the transfer component, it descends and places the hinge into the first preset position of the packaging box along the inclined carrier plate. Then the carrier plate rises. After receiving the hinge again, it rotates 180° and places the hinge into the second preset position of the packaging box. Then the carrier plate rotates back and rises. The above two steps are repeated until the hinges in the packaging box are neatly stacked. The width of the carrier plate can be adjusted according to the width of the packaging box so that the carrier plate can fill a layer of hinges every two times it enters the box, reducing the number of feeding times and improving production efficiency. At the same time, this device has wide compatibility with the size of the packaging box. It only needs to meet the lateral movement distance of the carrier plate to pack the box.

[0024] Hinges can be placed directly into the packaging box without the need for packaging bags, saving plastic packaging materials and making them more environmentally friendly. The hinges can be stacked symmetrically to maximize the use of space inside the packaging box.

[0025] The width of the support plate is similar to the overall width of the hinges after they are stacked, which reduces the pressure on the hinges during movement, avoids wear on the hinges during transfer, and ensures the integrity of the hinges.

[0026] The pushing component and auxiliary components work together to compress and stack multiple hinges to the same width as the inner width of the packaging box. The pushing component pushes multiple hinges from the output waiting plate to the carrier plate at the same time, which can reduce the number of pushing times and improve production efficiency.

[0027] The feeding mechanism and the box feeding mechanism are set up in an upper and lower space, which occupies a small area. After the positioning plate fixes the packaging box, the box support bucket opens the packaging box. The material feeding mechanism is put into the hinge in sequence. The degree of automation is high, which reduces the labor intensity of workers, improves the boxing efficiency, and reduces the production cost. Attached Figure Description

[0046] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0047] like Figure 1 and 2 As shown, the existing hinge 4 includes an arm body 42 and a hinge cup 41 hinged to the head end of the arm body 42, and a base 43 detachably disposed within the arm body 42 and extending to both sides. An automatic packing device for hinge products includes a material handling and conveying mechanism 1, a material feeding mechanism 2, and a box feeding mechanism 3. The material feeding mechanism 2 is located on one side of the material handling and conveying mechanism 1, and the box feeding mechanism 3 is located below the material feeding mechanism 2. The hinge 4 can be directly placed into a packaging box without a packaging bag, saving plastic packaging materials and being more environmentally friendly. The hinge 4 is stacked symmetrically, maximizing the use of space within the packaging box.

[0048] like Figure 3 As shown, the material handling and transfer mechanism 1 includes a loading gripper 11, a conveyor line 12, a rotating material handling gripper 13, a material transfer assembly 14, and a transfer assembly 15. The loading gripper 11 is located above the input end of the conveyor line 12, the material transfer assembly 14 is located on one side of the output end of the conveyor line 12, the rotating material handling gripper 13 is located between the output end of the conveyor line 12 and the material transfer assembly 14, and the transfer assembly 15 is located on one side of the material transfer assembly 14. After the rotating material handling gripper 13 picks up the hinge 4 on the conveyor line 12, it places it on the material transfer assembly 14 in a preset arrangement, and the material transfer assembly 14 pushes the hinge 4 onto the transfer assembly 15.

[0049] like Figure 4 and 5 As shown, the loading gripper 11 includes a first loading gripper 111, a second loading gripper 112, and a loading alignment component 114 that move in opposite directions and synchronously. Both the first loading gripper 111 and the second loading gripper 112 are provided with grooves 113. The grooves 113 are adapted to the shape of the base 43 of the hinge 4. The loading gripper 11 can grip the hinge 4 and transport it directly to the conveyor line 12 as needed, or the orientation of the hinge 4 can be adjusted by rotating the loading alignment component 114 before transporting it to the conveyor line 12.

[0050] like Figure 4 and 6As shown, a first arm-body limiting strip 121 and a second arm-body limiting strip 122 are fixedly installed above the conveyor line 12, parallel to each other. The distance between the first arm-body limiting strip 121 and the second arm-body limiting strip 122 is adapted to the width of the arm 42 of the hinge 4. The arm 42 slides between the first arm-body limiting strip 121 and the second arm-body limiting strip 122. A material control component 123 is provided near the output end of the conveyor line 12. The material control component 123 has a retractable material control block 1231. The material control block 1231 descends and locks the hinge 4, controlling the speed at which the hinge 4 slides towards the output end to match the speed at which the rotating material clamp 13 clamps the hinge 4 from the output end. Preferably, both the material control component 123 and the output end of the conveyor line 12 are provided with infrared sensors. If an infrared sensor is detected that the hinge at the output end of the conveyor line 12 is not clamped by the rotating material clamp 13, the material control block 1231 descends and locks the passing hinge 4.

[0051] like Figure 7 and 9 As shown, the rotating material handling gripper 13 includes a rotating component 131 and a clamping component 132 disposed on the rotating component 131. The clamping component 132 includes a first clamping member 1321 and a second clamping member 1322. The first clamping member 1321 and the second clamping member 1322 clamp the arm 42 of the hinge 4 from four directions respectively. The clamping component 132 is used to clamp the hinge 4 on the output end of the conveyor line 12. Then, the rotating component 131 drives the clamping component 132 to rotate the hinge 4 180° alternately and transport it to be placed horizontally on the material transfer assembly 14.

[0052] like Figure 8 and 9 As shown, the material transfer assembly 14 includes a material rail 141, a material support strip 142 slidably disposed on the material rail 141, and a pushing component 143. The material support strip 142 has a raised center, forming an inverted "V" shape. The inverted "V" shape design causes the hinge cup 41 of the hinge 4 on the material support strip 142 to tilt upwards, making it easier for adjacent hinges 4 to overlap. The hinges 4 gripped by the rotating material clamping claw 13 are arranged laterally on the material support strip 142. The pushing component 143 pushes the material support strip 142. The hinges 4 on the 42 cause the hinge cups 41 of adjacent hinges 4 to overlap on the arm body 42, and the hinges 4 are stacked on top of each other; when the hinges 4 on the waiting material support strip 142 reach the preset number, the waiting material support strip 142 slides along the waiting material slide rail 141 to the transfer assembly 15, the blocking plate 1541 of the blocking member 154 of the transfer assembly 15 descends to block the hinges 4, the inverted "V" shaped waiting material support strip 142 is pulled out and retracted, so that the hinges 4 remain on the output waiting plate 152 of the transfer assembly 15.

[0053] like Figure 10 and 11As shown, the transfer assembly 15 also includes a pushing component 151, which pushes the hinges 4 on the output waiting plate 152 onto the rotary feeding assembly 22. The pushing plate 1511 of the pushing component 151 and the first surrounding plate 1531 and the second surrounding plate 1532 on both sides of the auxiliary component 153 jointly push the hinges 4 on the output waiting plate 152 onto the rotary feeding assembly 22. The auxiliary component 153 first presses and stacks multiple hinges 4 from both sides to a width suitable for the carrier plate 223. The width of the carrier plate 223 is approximately equal to the overall width of the stacked hinges 4, reducing the pressure on the hinges 4 during movement, avoiding wear on the hinges 4 during transfer, and ensuring the integrity of the hinges 4. The pushing component 151 simultaneously pushes multiple hinges 4 from the output waiting plate 152 into the carrier plate 223. The pushing component 143 and the auxiliary component 153 work together to squeeze and stack multiple hinges 4 to the same width as the inner width of the packaging box. The pushing component 151 pushes multiple hinges 4 simultaneously from the output waiting plate 152 into the carrying plate 223, which can reduce the number of pushing times and improve production efficiency.

[0054] like Figure 12-15As shown, the feeding mechanism 2 includes a lifting assembly 21 and a rotating feeding assembly 22 mounted on the lifting assembly 21. The lifting assembly 21 includes a sliding component 211 and a lifting slide rail 212. The lifting slide rail 212 is fixedly mounted above the box feeding mechanism 3. The rotating feeding assembly 22 is slidably mounted on the lifting slide rail 212 via the sliding component 211. The rotating feeding assembly 22 includes a rotating shaft 221, a frame 222, a bearing plate 223, a baffle 224, and a feeding slide rail 225. The frame 222 is rotatably mounted on the rotating shaft 221, and the bearing plate 223 is vertically mounted on the frame 222. The carrier plate 223 is inclined. The high side of the carrier plate 223 has a feed port for the hinge 4 to enter, and the low side of the carrier plate 223 has a discharge port for the hinge 4 to slide out. The inclined carrier plate 223 can guide the hinge 4 to be placed smoothly into the packaging box. The height difference between the feeding height of the carrier plate 223 and the height of the hinge 4 in the packaging box is controlled at 3mm-4mm each time, which can reduce the damage caused by the hinge 4 colliding with each other when entering the box. The baffle 224 is fixedly set on the carrier plate 223 to block the discharge port. The carrier plate 223 slides upward along the feeding slide rail 225 to expose the discharge port, and the hinge 4 slides out from the discharge port. The rotating material handling gripper 13 arranges several hinges 4 in a preset pattern on the material transfer assembly 14. The transfer assembly 15 pushes the hinges 4 on the material transfer assembly 14 onto the carrier plate 223. The carrier plate 223 alternately and repeatedly descends into the packaging box of the box feeding mechanism 3 via the lifting assembly 21 when facing either the first direction 5 or the second direction 6, and then releases the material. Preferably, the second direction 6 is the opposite direction of the first direction 5. After receiving the hinge 4 pushed by the transfer component 15, the carrier plate 223 descends and places the hinge 4 into the first preset position of the packaging box along the inclined carrier plate 223. Then the carrier plate 223 rises. After receiving the hinge 4 again, it rotates 180° and places the hinge 4 into the second preset position of the packaging box. Then the carrier plate 223 rotates and rises. The above two steps are repeated until the hinge 4 in the packaging box is neatly stacked. The width of the carrier plate 223 can be adjusted according to the width of the packaging box so that the carrier plate 223 can fill one layer of hinge 4 every two times it enters the box. That is, when the first preset position and the second preset position are at the same height, the added area is equivalent to the bottom area of ​​the packaging box. This can reduce the number of times the material is put in and improve production efficiency. At the same time, this device has wide compatibility with the size of the packaging box. It only needs to meet the lateral movement distance of the carrier plate 223 to pack the box.

[0055] like Figure 16As shown, the box conveying mechanism 3 also includes a first packaging box conveying line 32 and a second packaging box conveying line 33; a positioning component 31 is provided on the first packaging box conveying line 32. The positioning component 31 includes a support platform 311 and four positioning plates 312 disposed on both sides of the first packaging box conveying line 32. The positioning plates 312 are telescopically disposed on the support platform 311. The positioning plates 312 are "L" shaped. The four positioning plates 312 extend simultaneously to clamp the four opposite corners of the packaging box and position the packaging box. The output end of the first packaging box conveyor line 32 is adjacent to the input end of the second packaging box conveyor line 33. A box-pushing assembly 34 is provided at the output end of the first packaging box conveyor line 32. The box-pushing assembly 34 includes a support component 341, a box-pushing slide rail 342, and a pushing elastic element 343 fixedly mounted on the box-pushing slide rail 342. The box-pushing slide rail 342 is slidably mounted on the support component 341, and the box-pushing slide rail 342 and the support component 341 slide together, allowing the pushing elastic element 343 to push the packaging boxes on the first packaging box conveyor line 32 onto the second packaging box conveyor line 33. The feeding mechanism and the box-feeding mechanism 3 are arranged in upper and lower spatial configurations, occupying a small area. After the positioning plate 312 fixes the packaging box, the box-supporting hopper opens the packaging box, and the material-discharging mechanism 2 sequentially inserts the hinge 4. This design achieves a high degree of automation, reduces the labor intensity of workers, improves packing efficiency, and reduces production costs.

[0056] The automatic packing device in this embodiment operates as follows:

[0057] A method for operating an automatic packing device for hinge products includes the following steps:

[0058] Step 1: The loading gripper 11 places the hinge 4 onto the conveyor line 12. The hinge 4 slides along the first arm body limiting strip 121 and the second arm body limiting strip 122. The material control component 123 controls the speed at which the hinge 4 slides toward the output end to match the speed at which the rotating swing gripper 13 picks up the hinge 4 from the output end.

[0059] Step 2: The rotating material clamping claw 13 clamps the arm 42 of the hinge 4 on the conveyor line 12 from four directions and rotates 180° alternately before transporting and placing it on the material transfer assembly 14. The pushing component 143 pushes the hinge 4 on the material support bar 142 so that adjacent hinges 4 are stacked on top of each other.

[0060] Step 3: When the hinge 4 on the waiting bar 142 reaches the preset number, the waiting bar 142 slides along the waiting slide rail 141 to the transfer assembly 15, the blocking plate 1541 descends to block the hinge 4, the waiting bar 142 is pulled out and retracted, so that the hinge 4 remains on the output waiting plate 152 of the transfer assembly 15.

[0061] Step 4: The first enclosure plate 1531 and the second enclosure plate 1532 on both sides work together to squeeze and stack multiple hinges 4 to a width that matches the bearing plate 223. The pushing component 151 pushes all the hinges 4 on the output waiting plate 152 into the bearing plate 223 at the same time.

[0062] Step 5: Positioning component 31 positions the packaging box below the rotating feeding component 22, and the carrier plate 223 alternately and repeatedly descends when facing the first direction or the second direction;

[0063] Step 6: The bearing plate 223 slides upward along the feeding slide rail 225 to expose the discharge port. Due to its own weight, the hinge 4 slides from the discharge port into the packaging box. After the packaging box is full, the box pushing assembly 34 pushes the packaging box from the first packaging box conveyor line 32 to the second packaging box conveyor line 33, and enters the next process.

[0064] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
