Description

Technical Field

[0001] The present invention relates to the technical field of signature feeding devices, and particularly to an automatic signature feeding device for a marshmallow machine. Background Art

[0002] Marshmallows are made of sugar and a small amount of flavoring agents, then heated and rotated in a marshmallow machine to form long, thin and light sugar filaments that look like cotton. When making marshmallows, it is a very common practice to use skewers. The function of the skewers is to help the operator collect the sugar filaments thrown out from the marshmallow machine to form the common spherical or cylindrical marshmallows. The skewers used in marshmallow machines usually have a pointed end and a flat end. Mainly for practicality and safety considerations, the pointed design makes it easy for the operator to insert the skewer into the fluffy sugar filaments, which can stably fix the marshmallow and ensure that the sugar filaments do not fall off easily during the production process. In addition, the pointed tip can more effectively penetrate the structure of the sugar filaments, so that the sugar filaments are evenly wound around the skewer. At the same time, the flat head design is for safety considerations, reducing the risk of accidental injury caused by the pointed tip during operation and delivery of marshmallows. This design also makes it convenient for the operator to hold the skewer. Holding the flat head part can more stably carry out the collection and sorting of sugar filaments.

[0003] Chinese Patent with publication number CN217498010U discloses an automatic signature feeding device for a marshmallow machine. Its structure includes a signature storage box, a signature feeding mechanism, a turning signature receiving mechanism, and a longitudinal signature feeding mechanism. The signature feeding mechanism is provided at the bottom of the signature storage box, and a signature outlet is provided on one side of the signature storage box. Along the conveying direction of the skewer body, the turning signature receiving mechanism is provided in front of the signature feeding mechanism, and the longitudinal signature feeding mechanism is provided on one side of the turning signature receiving mechanism. Compared with the existing signature feeding devices used in marshmallow machines, the structure and principle of this automatic signature feeding device for a marshmallow machine are simpler, with fewer actions during the operation of the device, and the signature feeding process is smooth and stable, which can greatly reduce the failure rate of the marshmallow machine during use.

[0004] However, the above-mentioned prior art has the following deficiencies: When taking out the skewers in the signature storage box, since the pointed and flat ends of a large number of skewers in the box may not be in the same direction, the operator needs extra time to adjust the direction of the skewers, which not only reduces work efficiency, but also may affect the production quality of marshmallows. Incorrect skewer directions will cause uneven winding of sugar filaments, resulting in poor appearance of the finished product and reducing customer satisfaction. In addition, the chaotic skewer directions may also increase operational chaos, leading to a risk of accidental injury during rapid operation. Summary of the Invention

[0005] The object of the present invention is to solve the problem that when taking out the skewers in the skewer storage box, since the pointed ends and flat ends of a large number of skewers in the box may not be in the same direction, the operator needs extra time to adjust the direction of the skewers, which not only reduces work efficiency but also may affect the quality of making marshmallows. Incorrect skewer direction will cause uneven winding of sugar filaments, resulting in poor appearance of the finished product and reduced customer satisfaction.

[0008] Among them, when the activating member drives the weighing device to make some skewers roll from the skewer storage box onto the placing disk and enter the placing grooves one by one as they roll, the activating member moves again, so that the push rod is inserted into the placing grooves in the placing disk accordingly, and the skewers in the placing grooves are pushed towards the adjusting rod until the center point of the skewer length is pushed onto the adjusting rod. At this time, although the lengths at both ends of the adjusting rod are the same, one end is pointed and the other end is flat, resulting in inconsistent weights at both ends, causing the flat end of the skewer to rotate around the central axis of the adjusting rod and fall into the collecting cylinder, so that all the skewers in the collecting cylinder have their pointed ends facing up and flat ends facing down.

The cooperation of the reset block and the first spring enables the push plate to automatically reset after each push, simplifying the operation process and enhancing the automation degree of the system. The design of the adaptation block and the second spring can flexibly adapt to signatures in different positions, ensuring that the signatures can be completely pushed into the push-in box during the pushing process, further improving the adaptability and stability of the weighing device;

[0018] 2. In the present invention, by adjusting the inclined surface of the placement tray and the design of the placement grooves in the device, the skewers can naturally fall into different placement grooves during the rolling process, avoiding the problems of skewer misalignment and accumulation. The coordinated action of the adjustment rod and the push rod can accurately push the center point of the skewer onto the adjustment rod. Utilizing the principle that the weights at both ends of the skewer are inconsistent, the skewer can automatically adjust to the state with the pointed end facing up and the flat end facing down, improving the accuracy and efficiency of adjustment. The blocking function of the blocking rod ensures that the skewers enter the adjustment device at the appropriate time point, reducing the chaos that may occur during the rolling process of the skewers;

[0019] 3.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0032] Refer to Figure 1 and Figure 6, in the embodiments of the present invention, an automatic stick feeding device for a marshmallow machine includes: a support frame 1, on which a stick storage box 2 for placing sticks is fixedly arranged, a weighing device 4 for batch feeding the sticks in the stick storage box 2 is arranged on the stick storage box 2, the support frame 1 is provided with an adjusting device 5 for adjusting the head and tail of the sticks pushed out from the stick storage box 2 by the weighing device 4 to make the pointed ends and flat ends of the sticks consistent, the stick storage box 2 is provided with a discharging device 6 for stacking multiple groups of sticks after the head and tail adjustment is completed, and the support frame 1 is provided with an activating member 3 for synchronously activating the weighing device 4, the adjusting device 5 and the discharging device 6 to make them move synchronously. The activating member 3 is composed of a hydraulic rod and a synchronous plate. The hydraulic rod is fixedly connected to the support frame 1, the movable end of the hydraulic rod penetrates through the support frame 1 and is fixedly connected to the synchronous plate;

[0033] The adjusting device 5 includes a placing plate 53 fixedly connected to the support frame 1. The placing surface of the placing plate 53 is an inclined surface. When the sticks fall on it, they will roll due to gravity. Multiple placing grooves 54 adapted to the sticks are provided on the placing plate 53. The placing grooves 54 are provided in multiple groups and are evenly opened on the placing surface of the placing plate 53. A blanking groove 55 is penetrated through the placing plate 53. The blanking groove 55 is arranged at the side end of the placing groove 54. An adjusting rod 56 is fixedly connected in the blanking groove 55. The adjusting rod 56 is inclined and the angle is the same as the placing surface of the placing plate 53. The vertex of the adjusting rod 56 and the bottom surfaces of multiple groups of placing grooves 54 are in the same plane. A collecting cylinder 57 is arranged below the blanking groove 55. The collecting cylinder 57 is fixedly connected to the support frame 1. One end of the activating member 3 is fixedly connected with a push rod 52. One end of the push rod 52 penetrates through the placing plate 53 and is slidably inserted into the placing groove 54. Multiple groups of push rods 52 are provided, and each group of push rods 52 is slidably inserted into a group of placing grooves 54;

[0034] Among them, when the activating member 3 drives the weighing device 4 to make some sticks roll from the stick storage box 2 onto the placing plate 53, multiple groups of sticks roll on it due to the inclined placing surface of the placing plate 53. During the rolling process, the first group of sticks fall into the first group of placing grooves 54, enabling the next group of sticks to pass over it and fall into the next group of placing grooves 54 until all the sticks enter different placing grooves 54 respectively. Then the activating member 3 moves again, causing the push rod 52 to be inserted into the placing grooves 54 in the placing plate 53, and pushing the sticks in the placing grooves 54 towards the adjusting rod 56 until the center point of the stick length is pushed onto the adjusting rod 56. At this time, although the lengths of both ends of the adjusting rod 56 are the same, one end is a pointed end and the other end is a flat end, resulting in inconsistent weights at both ends, causing the flat end of the stick to rotate around the central axis of the adjusting rod 56 and fall into the collecting cylinder 57, making all the sticks in the collecting cylinder 57 have their pointed ends facing up and flat ends facing down.

[0035] Refer to Figure 2 and Figure 6, a storage slot 21 is placed at the top of the signature storage box 2. The bottom end of the storage slot 21 is a slope. A rolling groove 22 is provided inside the signature storage box 2. One end of the rolling groove 22 is connected to the lowest end of the storage slot 21 in a through manner, and the other end of the rolling groove 22 is connected to the side of the signature storage box 2 where the adjustment device 5 is located. The rolling groove 22 is Z-shaped. The adjustment device 5 further includes a stop rod 51 fixedly connected to the activation member 3, and one end of the stop rod 51 penetrates the signature storage box 2 and is slidably inserted into the rolling groove 22. When the activation member 3 is activated, the stop rod 51 is inserted into the rolling groove 22 to block the rolling of the signature. The insertion of the stop rod 51 can prevent the signature from rolling onto the placement plate 53 prematurely, ensuring that the signature enters the adjustment device 5 at an appropriate time point.

[0036] With the above solution: The Z-shaped design of the rolling groove 22 effectively slows down the rolling speed of the signature, making it easier to control the signature before it enters the adjustment device 5, reducing the problems of misalignment or accumulation that may occur during the rolling of the signature. The blocking function of the stop rod 51 prevents the signature from rolling onto the placement plate 53 prematurely, ensuring that all signatures can be precisely controlled and guided before entering the adjustment device 5.

[0037] Refer to Figure 7 , a feeding port is provided in a through manner at the top of the collection cylinder 57. A discharge port is provided on the side of the collection cylinder 57 where the discharge device 6 is located. A limiting plate 571 is fixedly connected to the bottom end inside the collection cylinder 57. A guiding block one 572 is fixedly connected to the side end inside the collection cylinder 57. A guiding block two 573 is fixedly connected to the side end of the limiting plate 571. The contact surfaces of the signature with the guiding block one 572 and the guiding block two 573 are slopes, and both are inclined towards the discharge port of the discharge device 6. There are two groups of the guiding block one 572 and the guiding block two 573, symmetrically distributed on both sides of the limiting plate 571. When the signature falls into the collection cylinder 57, it contacts the slopes of the guiding block one 572 and the guiding block two 573, and is discharged from the discharge port of the collection cylinder 57 under the guidance of the slope and the gravity of the signature.

[0038] With the above solution: The slope design of the guiding block one 572 and the guiding block two 573 helps the signature to slide smoothly to the discharge port under the action of gravity, reducing the possibility of the signature accumulating or getting stuck inside the collection cylinder 57 and improving the discharge efficiency.

[0039] Refer to Figures 3 to 5, the component device 4 includes a push plate 41 that is slidably inserted into the signature storage box 2. The push plate 41 is L-shaped and is located at the side end of the through hole of the rolling groove 22 and the storage groove 21. One end of the push plate 41 penetrates through the signature storage box 2 and is fixedly connected to the synchronization plate in the activation member 3. One end of the signature storage box 2 is connected to a push-in box 42 in a through manner. The push-in box 42 is also arranged at the side end of the through hole of the rolling groove 22 and the storage groove 21. The push plate 41 and the push-in box 42 are symmetrically distributed on both sides of the signature storage box 2. A reset block 43 is slidably connected in the push-in box 42. The reset block 43 is composed of a set of sliding blocks arranged in the push-in box 42 and slidably connected to the inside of the push-in box 42, and a U-shaped reset plate sleeved outside the push-in box 42. A first spring 44 is fixedly connected to the reset plate in the reset block 43. One end of the first spring 44 is fixedly connected to the signature storage box 2. Four groups of the first springs 44 are provided and are evenly distributed at the side end of the reset plate. When the hydraulic rod in the activation member 3 drives the synchronization plate fixedly connected to the movable end of the hydraulic rod to move, the push plate 41 is inserted into the storage groove 21, thereby pushing the signature between the push plate 41 and the reset block 43 to move into the push-in box 42. During the movement, the signature will push the reset block 43 to move and cause the first spring 44 to be stretched by force until the short side of the L-shaped push plate 41 is moved to the connection port of the signature storage box 2 and the push-in box 42, and the long side of the L-shaped push plate 41 separates the signatures in the storage groove 21, making the space for the signatures on one side of the communication port between the rolling groove 22 and the storage groove 21 larger. At this time, due to the larger space, the signatures squeezed above the communication port will fall towards the long side of the L-shaped push plate 41, so that multiple groups of signatures are no longer in a static state of mutual extrusion, thereby causing the signatures to roll into the rolling groove 22.

[0040] Adopting the above solution: The L-shaped push plate 41 can accurately push into the storage groove 21, ensuring that only a certain number of signatures are pushed each time, avoiding the situation of pushing out too many signatures at one time, which may cause chaos or jamming. This precise metering design helps to maintain the stability and efficiency of the entire system. The reset block 43 is composed of a sliding block and a U-shaped reset plate, and can automatically reset under the elastic force of the first spring 44. After the L-shaped push plate 41 pushes the signature into the push-in box 42, the reset block 43 will automatically return to its original state, preparing for the next pushing operation. This automatic reset function simplifies the operation process and improves the automation degree of the system.

[0041] Refer to Figure 5, at the communication port between the signature storage box 2 and the pushing box 42, a receiving groove 45 is provided. There are two groups of receiving grooves 45, symmetrically arranged on both sides of the communication port. A set of adapting blocks 47 are slidably inserted into each group of receiving grooves 45. The adapting blocks 47 are semi-cylindrical. One end of the adapting block 47 is fixedly connected to a second spring 46, and one end of the second spring 46 is fixedly connected to the inner wall of the receiving groove 45. There are four second springs 46 provided on each set of adapting blocks 47. During the moving process, since the signature sticks are not neatly arranged, some signature sticks may partially contact the pushing plate 41. During the pushing process, they abut against the semi-cylindrical adapting blocks 47, causing the adapting blocks 47 to move into the receiving groove 45 under force and compressing the second spring 46. Thus, only the signature sticks that partially contact the pushing plate 41 can be completely pushed into the pushing box 42 during the pushing process.

[0042] Adopting the above solution: Through the semi-cylindrical adapting blocks 47, the signature sticks at different positions can be flexibly adapted. When the signature sticks partially contact the pushing plate 41, the adapting blocks 47 can move into the receiving groove 45 under force, enabling the signature sticks to be completely pushed into the pushing box 42. The second spring 46 will return to its original state after the signature sticks are completely pushed in, ensuring that the adapting blocks 47 can be flexibly operated again. This design improves the adaptability of the weighing device 4 to signature sticks at different positions.

[0043] Refer to Figures 8 to 9 , the discharging device 6 includes a discharging block 63 fixedly connected to the support frame 1. The corresponding surface of the discharging block 63 and the discharging port of the collecting cylinder 57 is an inclined surface. A plurality of discharging grooves 64 are provided on the discharging block 63, evenly distributed on the inclined surface of the discharging block 63. The bottom end of the discharging block 63 is fixedly connected to a connecting rod 65. The connecting rod 65 is U-shaped. A supporting rod 66 is rotatably connected to the connecting rod 65. There are a plurality of supporting rods 66. Each group of supporting rods 66 is arranged directly below a group of discharging grooves 64, and the top end of each group of supporting rods 66 is fixedly connected to a group of elastic ropes 67. One end of the elastic rope 67 is fixedly connected to the bottom end of the discharging block 63. The discharging device 6 further includes a connecting plate 61 fixedly connected to the bottom end of the reset block 43. One end of the connecting plate 61 is fixedly connected to a stacking plate 62. The stacking plate 62 is attached to the discharging block 63. When the activating member 3 resets, it drives the stacking plate 62 to reset synchronously, thereby pushing the signature sticks stacked on the inclined surface of the discharging block 63, causing the first group of signature sticks to fall into the first group of discharging grooves 64, and the next group of signature sticks to pass over it and fall into the next group of discharging grooves 64 until all the signature sticks enter different discharging grooves 64 respectively. After the signature sticks enter the discharging grooves 64, under the action of gravity, they slide downward in the discharging grooves 64 until the bottom ends of the signature sticks abut against the supporting rods 66. When the signature sticks are needed, press down the supporting rods 66, causing the supporting rods 66 to rotate around the connecting rod 65 and stretching the elastic ropes 67, increasing the distance between the supporting rods 66 and the bottom end of the discharging block 63 until the signature sticks are taken out. After taking out, release the supporting rods 66, and the supporting rods 66 will reset under the action of the elastic ropes 67.

[0044] Using the above solution: By pressing down on the support rod 66, the support rod 66 rotates around the connecting rod 65, and the elastic cord 67 is stretched under force, increasing the distance between the support rod 66 and the bottom end of the discharging block 63 until the skewers are taken out. After taking out, release the support rod 66, and the support rod 66 resets under the action of the elastic cord 67. This design makes the discharging process of the skewers controllable, and users can take out the skewers one by one or in batches according to needs, improving the flexibility of use. When the stacking plate 62 moves, it pushes the skewers stacked on the discharging block 63, so that each group of skewers orderly falls into different discharging grooves 64. This coordinated movement ensures the orderly stacking of the skewers during the discharging process, reducing the chaos and misalignment between the skewers.

[0045] The working principle of the present invention is as follows: When in use, multiple groups of skewers are placed in the storage slots 21 in the skewer storage box 2, and the skewers roll towards the rolling slots 22 along the inclined surface at the inner bottom end of the storage slots 21. Due to the mutual extrusion of multiple groups of skewers being in a static state, they cannot fall into the rolling slots 22. Then, the hydraulic rod in the activation member 3 is started, causing the hydraulic rod to drive the synchronous plate fixedly connected to the movable end of the hydraulic rod to move, and causing the push plate 41, the blocking rod 51, and the push rod 52 fixedly connected to the synchronous plate to move synchronously. As a result, the push rod 52 is inserted into the placement slot 54, the blocking rod 51 is inserted into the rolling slot 22 to block the rolling slot 22, and the push plate 41 is inserted into the storage slot 21, thereby pushing the skewers between the push plate 41 and the reset block 43 to move into the pushing box 42. During the movement, since the skewers are not neatly arranged, some skewers may partially contact the push plate 41, and thus abut against the semi-cylindrical adaptation block 47 during the pushing process, causing the adaptation block 47 to be forced to move into the receiving slot 45 and compressing the second spring 46, so that only the skewers that partially contact the push plate 41 can be completely pushed into the pushing box 42 during the pushing process. When the skewer is completely pushed into the pushing box 42, the skewer will push the reset block 43 to move and stretch the first spring 44 until the short side of the L-shaped push plate 41 is moved to the connection port between the skewer storage box 2 and the pushing box 42, and the long side of the L-shaped push plate 41 separates the skewers in the storage slot 21, increasing the space for the skewers on one side of the communication port between the rolling slot 22 and the storage slot 21. At this time, due to the increased space, the skewers squeezed above the communication port tilt towards the long side of the L-shaped push plate 41, causing the multiple groups of skewers to no longer be in a static state of mutual extrusion, so that the skewers roll into the rolling slot 22 until they abut against the blocking rod 51 inserted in the rolling slot 22. Then, the hydraulic rod in the activation member 3 is started again to drive the push plate 41, the blocking rod 51, and the push rod 52 to reset. During the reset process, the reset block 43 is no longer stressed, causing the first spring 44 to return to its original length and driving the reset block 43 to reset, thereby causing the reset block 43 to push the skewers in the pushing box 42 to re-enter the storage slot 21. After the skewers completely enter the storage slot 21, the adaptation block 47 is no longer stressed and resets under the action of the second spring 46. At the same time, the push plate 41 and the blocking rod 51 are respectively withdrawn from the rolling slot 22 and the placement slot 54. At this time, the skewers in the rolling slot 22 are no longer blocked by the blocking rod 51 and continue to roll in the rolling slot 22 until they fall on the placement plate 53. Since the placement surface of the placement plate 53 is an inclined surface, the skewers roll on it. During the rolling process, the first group of skewers fall into the first group of placement slots 54, enabling the next group of skewers to pass through on it and fall into the next group of placement slots 54. Until all the skewers enter different placement slots 54 respectively, the activation member 3 repeats the previous movement again, causing the push rod 52 to be inserted into the placement slot 54, the blocking rod 51 to be inserted into the rolling slot 22, and the push plate 41 to be inserted into the storage slot 21. When the push plate 41 is inserted into the storage slot 21 and drives the reset block 43 to move,Synchronously move the stacking board 62 connected to the reset block 43 to the other side of the discharging block 63. When the push rod 52 is inserted into the placing groove 54, push the skewers in the placing groove 54 towards the adjusting rod 56 until the center point of the skewer length is pushed onto the adjusting rod 56. At this time, although the lengths at both ends of the adjusting rod 56 are the same, one end is pointed and the other end is flat, resulting in inconsistent weights at both ends, causing the flat end of the skewer to rotate around the central axis of the adjusting rod 56 until the flat end of the skewer hits the limiting plate 571 and maintains a vertical state, falling on both sides of the limiting plate 571, making all the skewers in the collecting cylinder 57 have their pointed ends facing up and flat ends facing down. Then, under the guiding of the inclined surfaces of the guiding block one 572 and the guiding block two 573, move towards the discharging block 63 and stack multiple groups of skewers on the inclined surface of the discharging block 63. After that, the activating part 3 resets again, causing the reset block 43 to reset accordingly and driving the stacking board 62 to reset synchronously. When the stacking board 62 resets, it pushes the skewers stacked on the inclined surface of the discharging block 63, causing the first group of skewers to fall into the first group of discharging grooves 64, and the next group of skewers to pass over it and fall into the next group of discharging grooves 64 until all the skewers enter different discharging grooves 64 respectively. After the skewers enter the discharging grooves 64, they slide down in the discharging grooves 64 under the action of gravity until the bottom ends of the skewers abut against the supporting rod 66. When the skewers are needed, press down the supporting rod 66, causing the supporting rod 66 to rotate around the connecting rod 65 and stretching the elastic cord 67, increasing the distance between the supporting rod 66 and the bottom end of the discharging block 63 until the skewers are taken out. After taking out, release the supporting rod 66, and the supporting rod 66 resets under the action of the elastic cord 67; Through the pushing of the push plate 41 in the weighing device 4 and the L-shaped design, it is ensured that only a certain number of skewers are pushed each time, avoiding the problems of skewer accumulation or jamming, thereby improving the accuracy and efficiency of weighing control. The cooperation of the reset block 43 and the first spring 44 enables the push plate 41 to automatically reset after each push, simplifies the operation process, and enhances the automation degree of the system. The design of the adapting block 47 and the second spring 46 can flexibly adapt to skewers at different positions, ensuring that the skewers can be completely pushed into the pushing box 42 during the pushing process, further improving the adaptability and stability of the weighing device 4. Through the design of the inclined surface of the placing disk 53 and the placing groove 54 in the adjusting device 5, the skewers can naturally fall into different placing grooves 54 during the rolling process, avoiding the problems of skewer misalignment and accumulation. The coordinated action of the adjusting rod 56 and the push rod 52 can accurately push the center point of the skewer onto the adjusting rod 56. Utilizing the principle of inconsistent weights at both ends of the skewer, the skewer can be automatically adjusted to a state with the pointed end facing up and the flat end facing down, improving the accuracy and efficiency of adjustment. The blocking effect of the blocking rod 51 ensures that the skewers enter the adjusting device 5 at an appropriate time point, reducing the chaos that may occur during the rolling process of the skewers. Through the design of the inclined surface of the discharging block 63 and the discharging grooves 64 in the discharging device 6, the skewers can fall into different grooves in an orderly manner, avoiding chaos and misalignment of the skewers during the discharging process. The cooperation of the supporting rod 66 and the elastic cord 67,The discharging process of the skewers is controllable, allowing users to take out the skewers one by one or in batches according to their needs, improving the flexibility of use. The movement of the stacking plate 62 ensures the orderly stacking of the skewers during the discharging process, further improving the discharging efficiency and the coordination of the system.
