Description

Technical Field

[0001] This invention relates to the field of tableware production machinery technology, specifically to an automatic flipping and straightening device for disposable spoons or forks. Background Technology

[0002] Disposable wooden or bamboo spoons and forks are typically bundled together in end-to-end order during production for ease of processing, transport, and packaging. On existing production lines, a hoist lifts the bundles, distributes them onto a chute straightening device, and then conveys them forward onto a belt conveyor. At this stage, the bundles are not separated by end; to bundle them, they need to be further sorted in end-to-end order. This sorting process is currently done manually, which is inefficient and requires a large workforce. To address this issue, an image recognition system has been developed to automatically identify bundles in different orders and then use a suction nozzle to turn them around. While this method perfectly replaces manual labor, the significantly increased usage and maintenance costs place a heavy burden on manufacturers. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a disposable spoon and fork automatic flipping and straightening device with low usage and maintenance costs.

[0004] The technical solution of the present invention is: a disposable spoon and fork automatic flipping and straightening device, including a frame, a straightening trough, and a belt conveyor. The straightening trough is provided with several corrugated grooves. The straightening trough is obliquely arranged. The conveyor is horizontally arranged. The straightening trough is set on a vibrating frame. The vibrating frame is provided with a vibrator. The vibrating frame and the frame are connected by an elastic vibration support device. At the lower end of the straightening trough, a pair of frustum-shaped flipping wheels are provided at each groove. The small bottom surfaces of the two flipping wheels are opposite each other and spaced apart by a distance greater than the width of the embryo shank but less than the width of the embryo head. The side of the flipping wheel is provided with an annular friction part at the corner of the small bottom surface. The flipping wheels are coaxially arranged and connected to the frame or vibrating frame through a bearing seat. They are driven to rotate by a drive device. The top of the annular friction part is adapted to the position of the lower end of the groove of the straightening trough.

[0005] The technical advantages of this invention are: simple structure, low cost, and convenient use and maintenance. It can save a significant amount of labor and equipment costs and improve work efficiency. By cleverly combining the different shapes and sizes of the spoon or fork's head and handle with the straightening wheel, the spoon or fork will rotate significantly when the handle is in front, thus achieving the purpose of straightening the spoon or fork. This device can be used for raw food pieces or for finished spoons, forks, and other products with similar shapes. Attached Figure Description

Detailed Implementation

[0007] like Figures 1 to 4 As shown, the disposable spoon and fork automatic tilting and straightening device includes a frame 1, a straightening trough 2, and a belt conveyor 3. The straightening trough 2 has several corrugated grooves 4 arranged at an angle, while the conveyor 3 is horizontally positioned. The straightening trough 2 is mounted on a vibrating frame 5, which has a vibrator 6. The vibrating frame 5 is connected to the frame 1 by an elastic vibration support device 7. This elastic vibration support device can be a vibrating screen spring, a rubber spring, etc. In this embodiment, an AB elastic vibration support frame is used. At the lower end of the straightening trough 2, a pair of frustum-shaped tilting wheels 8 are correspondingly provided at each groove 4. Two rotating wheels 8 have their small bottom surfaces facing each other and spaced apart by a distance greater than the width of the embryo shank but less than the width of the embryo head. The rotating wheels 8 have annular friction parts 9 at the corners of their small bottom surfaces. The rotating wheels 8 are coaxially arranged and connected to the frame 1 or vibrating frame 5 via a shaft seat 10. They are driven to rotate by a drive device, which can be a motor that drives the rotation via a belt or other means. The rotation direction of the rotating wheels is adapted to the downward sliding direction of the embryo. The top of the annular friction part 9 is adapted to the position of the lower end of the slide groove 4 of the straightening groove 2, so that the head of the embryo can contact the annular friction part when it slides down the slide groove. As the wafer slides down to the tilting wheel, if the head is in front, it contacts the friction part of the tilting wheel first and is lifted by the friction part, being thrown forward tangentially. The narrower handle does not interact with the friction part, and the rear end of the handle remains in a falling posture when it reaches the tilting wheel. Thus, the friction part lifts the head, causing the wafer to fall onto the conveyor in a head-for-hand position. If the handle is in front, it does not contact the friction part when it reaches the tilting wheel, maintaining a falling posture. The head, arriving later, is temporarily stopped from falling due to the lifting effect of the friction part. This time difference causes the wafer to tilt, resulting in a head-for-hand position as it falls onto the conveyor. The vibrator can be a vibrating motor, providing additional power for the downward movement.

[0008] The annular friction part 9 is an elastic ring made of a rubber material with high friction. The corner of the flipping wheel 8 is provided with an annular groove, and the annular friction part 9 is fitted onto the annular groove.

[0009] The straightening groove 2 has multiple levels, and each level of the straightening groove 2 is equipped with a flipping wheel 8 at its lower end. The multi-level setting can improve the success rate of flipping the reversed embryo slices and greatly reduce the probability of the embryo slices not being straightened.

[0010] The straightening groove 2 is provided with baffles 10 on both sides of each slide groove 4. The baffles can effectively limit the trajectory of the rapidly sliding blanks from accidentally leaving the slide groove. In multi-stage straightening grooves, the first stage straightening groove may not have baffles.

[0011] Above the straightening trough 2, at the feed inlet, there are several rows of staggered distributing needles 11. The distributing needles 11 are vertically fixed on the support, and the support is fixed on the vibrating frame 5.

[0012] The top surface of the belt conveyor 3 is provided with several isolation plates 12, which divide the conveyor into multiple strip channels. Each channel corresponds to the position of the chute 4 of the straightening trough 2. A certain gap is left between the isolation plates and the conveyor belt. The isolation plates 12 are connected to the frame 1 through a bracket. When the belt conveyor has multiple stages, the isolation plates at the junction with the straightening trough can be appropriately extended on both sides corresponding to the turning wheel to form a "V" shape, which has the same function as the baffles on both sides of the chute.

[0013] The support for the isolation plate 12 includes a crossbar 13, a spacer 14, a locking ring 15, a support arm 16, and a support 17. The isolation plate 12 has openings and is threaded onto the crossbar 13. The isolation plates 12 are spaced apart by the spacers 14 fitted onto the crossbar 13. The two outer isolation plates 12 are respectively fixed to the outside by the locking rings 15 fitted onto the crossbar 13. Both ends of the crossbar 13 are fixed to the support arm 16. The support arm 16 and the support 17 are connected by bolts, and the support 17 is fixed to the frame 1. The connecting bolt holes between the support arm and the support can be elongated holes to facilitate adjustment of the gap between the isolation plate and the conveyor belt.

[0014] The locking ring 15 consists of two half-rings connected by bolts, which lock the two half-rings onto the crossbar. This structure replaces the set screw locking, preventing the set screw from scratching the surface of the crossbar and facilitating assembly and disassembly.

[0015] The crossbar 13 and the support arm 16 are detachably connected.

[0016] The support arm 16 is provided with a "C"-shaped connecting hole with an opening on one side. The crossbar 13 is inserted into the "C"-shaped connecting hole, and the opening of the "C"-shaped connecting hole is provided with bolts that pass through both sides of the opening for locking.
