Description

Technical Field

[0001] The present invention relates to the technical field of tableware equipment, and in particular to a self-service tableware dispensing device and a use method thereof. Background Art

[0002] As the catering industry pays more and more attention to service efficiency and hygiene and safety, self-service tableware taking devices are widely used in public dining places such as restaurants, canteens, and cafes. Usually, a mechanical structure is used to centrally stack, automatically distribute, and take out tableware such as knives, forks, and spoons, thereby avoiding cross contact when users take tableware, improving the overall dining experience and hygiene management level.

[0003] Existing tableware retrieval devices mostly use a combination of stacking storage and unloading mechanisms to push the bottom or front tableware to the retrieval port through mechanical pushing, paddle structures, rotating brackets or electronically controlled drive components. However, in actual applications, there are still several key issues that have not been effectively resolved:

[0004] 1) The problem of tableware jamming or multiple pieces falling is prominent. Due to the irregular shape or irregular placement of tableware, it is easy for tableware to be jammed or "multiple pieces falling at one time" to occur in the stacking unloading mechanism, which seriously affects the stability of the tableware and the user's operating experience.

[0005] 2) Complex structure and delayed response. Some solutions use motors, transmission shafts, sensors and other drive control components to complete the unloading action, which not only has high manufacturing costs and complex maintenance, but also has problems such as slow response and limited life.

[0006] 3) Poor adaptability and fault tolerance. In scenarios where users frequently change tableware of different types (such as wooden forks, wooden spoons, and table knives), existing devices often need to be replaced or re-debugged, which has poor adaptability and limited use.

[0007] 4) The cycle supply logic of "single take - automatic next piece in place" cannot be realized. After the user takes away the tableware, some devices do not synchronously complete the precise positioning and preparation of the next piece of tableware, requiring additional operation or waiting time.

[0008] To solve the above problems, some existing technologies have proposed to control the tableware to slide down by setting a slide slot and a movable baffle, or to design a matching structure of the tableware body to realize the position recognition. However, these methods either rely on matching special tableware, which limits the versatility, or lack a coordination mechanism in terms of multi-mold linkage and continuous retrieval, and it is still difficult to achieve high-precision, repeatable, and sequential retrieval control without the need for electronic control.

[0009] Therefore, it is necessary to provide a tableware taking device with simple and novel structure, precise control and sensitive response to solve the above problems. Summary of the invention

[0010] In view of the technical problems in the prior art mentioned above, such as easy jamming during tableware taking, inability to achieve accurate single-piece dispensing, and complex mechanisms, a self-service tableware dispensing device and its use method are provided. The present invention realizes the cyclical tableware taking logic of "single-piece release, automatic reset, and taking linkage" by coordinating the upper and lower offset linkage mold structure, the spring reset mechanism, and the taking action trigger mechanism. Without the need for a complex electrical control system, the tableware distribution process can be efficiently completed through mechanical coordination, improving the efficiency of taking and the user experience, and is particularly suitable for public self-service scenarios with high requirements for structural stability and hygiene and safety.

[0011] The technical means adopted by the present invention are as follows:

[0012] A self-service tableware dispensing device comprises a housing and at least one group of silo mechanisms arranged in the housing, wherein the silo mechanisms comprise:

[0013] The tableware accommodating bin has a first guide plate and a second guide plate arranged opposite to each other, and is used to accommodate a plurality of stacked tableware and define the stacking state thereof;

[0014] The tableware dropping bin has an upper mold, a middle mold and a lower mold arranged in sequence along the vertical direction, and is used for the tableware to slide sequentially to the taking position of the lower mold;

[0015] Among them, the upper mold, the middle mold and the lower mold are all provided with channels for the passage of tableware. In the initial state, the middle mold is aligned with the channel of the upper mold and misaligned with the channel of the lower mold; the user presses the first switch linked to the middle mold to drive the middle mold to align with the channel of the lower mold and misalign with the channel of the upper mold, so that the first piece of tableware falls into the retrieval position; subsequently, the linkage component is driven by pulling the tableware handle to reset the misaligned structure between the molds, so that the next piece of tableware falls into the retrieval position.

[0016] Furthermore, the tableware accommodating bin is arranged on the upper mold bearing platform of the upper mold, the accommodating space in the guide plate follows the shape of the upper mold channel, and the upper mold channel has a certain height.

[0017] Furthermore, the middle mold is placed in the bottom of the upper mold, including a middle mold supporting platform and a vertical plate arranged thereon, the middle supporting platform is provided with a middle mold channel, the vertical plate is arranged at the tail end of the middle mold channel, and a fixing rod for installing a reset spring is provided on one side of the vertical plate facing the middle mold channel; the other side is connected to the rack of the linkage assembly.

[0018] Furthermore, the thickness of the middle mold is less than or equal to the thickness of the tableware, and a first buffer is provided at the tail end of the middle mold channel and a second buffer is provided at the front end.

[0019] Furthermore, the lower mold is a split structure, having two relatively arranged mold bodies for forming a space for tableware to slide down, the mold body comprising a lower mold supporting platform arranged at the upper end, a tableware sliding and conveying cavity and an inclined slide for a tableware taking position; the lower mold supporting platform is provided with a lower mold channel, and the tail end of the tableware sliding and conveying cavity is provided with a limit block for limiting the sliding of the tableware head.

[0020] Furthermore, a plurality of support rods arranged in a descending manner in sequence are provided in the tableware sliding conveying cavity of the lower mold, forming a slideway for the tableware to slide down; and a space for installing the linkage assembly is provided at the tableware taking position of the lower mold.

[0021] Furthermore, the linkage assembly includes a linkage rod, and a first transmission member is provided at the upper part of the linkage rod. The teeth on the first transmission member are meshed with the gear provided on the middle mold supporting platform, and the transmission is transmitted to the rack to push the vertical plate to move forward; a second transmission member and a third transmission member arranged opposite to the second transmission member and the third transmission member are provided with meshing teeth. When the head of the tableware passes through, the second transmission member and the third transmission member are driven to rotate outward and open to take out the tableware.

[0022] Furthermore, the tableware removal position of the lower mold is also provided with a dust cover, including a dust cover body, a dust cover and a tableware removal outlet below, the dust cover body is provided with a first switch hole matching the first switch, and the side wall of the dust cover body is provided with a positioning protrusion that is clamped and fixed to the side panel of the lower mold.

[0023] Furthermore, a support base and an anti-slip member are provided at the bottom of the cover shell.

[0024] The present invention also provides a method for using the self-service tableware dispensing device as described above, comprising the following steps:

[0025] S1, stacking a plurality of tableware in the same direction into a tableware storage bin, and limiting the stacking state by a first guide plate and a second guide plate, so that the tableware slides downward into an upper mold by gravity;

[0026] S2. In the initial state, the middle mold is aligned with the channel of the upper mold and misaligned with the channel of the lower mold, and the lowermost tableware is restricted by the misaligned structure and stays in the middle mold;

[0027] S3, the user presses the first switch to align the channels of the middle mold with the lower mold and misalign the channels of the upper mold, so that the first tableware falls into the tableware sliding and conveying cavity of the lower mold. At this time, the middle mold returns to the initial state under the rebound of the reset spring, and the next tableware automatically slides into and stays in the middle mold;

[0028] S4, the tableware slides to the taking position via the inclined slide, the handle part of the tableware extends out of the cover, and the head of the tableware is fixed at the positioning position by the limit block;

[0029] S5. When the user pulls the cutlery handle to take out the cutlery, the cutlery head triggers the linkage assembly, which drives the middle mold from being misaligned with the channel of the lower mold to being aligned through the linkage assembly, so that the next cutlery automatically falls to the lower mold, completing a taking cycle.

[0030] Compared with the prior art, the present invention has the following advantages:

[0031] 1. The present invention realizes the step-by-step limitation and single-piece release of tableware during the falling process through the dislocation control and linkage switching between the upper, middle and lower three-layer molds, avoids the simultaneous sliding or jamming of multiple pieces of tableware, improves the accuracy and stability of the production, and realizes precise single-piece feeding control.

[0032] 2. The present invention adopts a purely mechanical structure design, without the need for electronic components such as motors and sensors. The user can trigger the mold linkage and complete the placement of the next piece of tableware only by pulling the tableware, and automatically reset it with the spring reset structure.

[0033] 3. The silo mechanism provided by the present invention is modularly designed, and the corresponding mold components can be quickly replaced according to the shape and size of the tableware types (such as wooden forks, wooden spoons, wooden knives, etc.). It has strong adaptability and high versatility, and is suitable for flexible use in different scenarios.

[0034] 4. The present invention adopts a closed cover structure. The head of the cutlery is always located inside the cover during the taking process, and only the handle is exposed. Combined with the limiting structure and dust cover design, the risk of contamination is effectively reduced, which meets the public health and safety requirements.

[0035] In summary, the device provided by the present invention has a reasonable and simple structure, sensitive response, reliable operation, no need for electric drive, and relies on mechanical linkage to complete tableware distribution. It has the advantages of single-piece access, sequential supply, pollution prevention, and low maintenance cost. It is suitable for high-frequency usage scenarios such as buffet restaurants, shared kitchens, and canteens, and has wide application and promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] The embodiment of the present invention provides a self-service tableware dispensing device, which realizes the process of sequential unloading, automatic positioning and mechanically triggered cyclic taking of tableware by means of the staggered linkage structure of the multi-layer mold and the spring reset mechanism.

[0059] Example 1

[0060] like Figure 1 and Figure 2As shown, a structure of a self-service tableware dispensing device includes a housing 1 and three groups of silo mechanisms 2 arranged in the housing 1. The housing 1 is provided with a support base 11 and an anti-slip member 12 at the bottom. The support base 11 is formed as two side protrusions extending from the side wall of the bottom of the housing 1. The anti-slip member 12 can be an anti-slip structure such as a suction cup anti-slip pad or a silicone column, which is used to stably place the device on a desktop or operating table (such as Fig. 9 The cover shell 1 and the silo mechanism 2 of the present invention can be made of ABS engineering plastics or food-grade polypropylene materials.

[0061] like Figure 3 As shown, the bin mechanism 2 includes a tableware receiving bin 21 , a tableware dropping bin 22 and a dust cover 23 .

[0062] Specifically, the cutlery storage bin 21 is formed by a first guide plate 211 and a second guide plate 212 that are arranged opposite to each other to form a narrow and long cavity extending vertically downward. The gap between the guide plates is slightly larger than the width of the cutlery, and is used to accommodate a plurality of stacked cutlery 3 and define their stacking state. The cutlery 3 can be a spoon, a knife or a fork, and a positioning groove 31 is provided at the handle of the cutlery 3. As shown in the figure, the inner wall portion of the first guide plate 211 is an arc shape that follows the shape of the spoon, such as the bin mechanism of the knife or fork, and this part will be replaced with a structure that follows the shape thereof; the inner wall portion of the second guide plate 212 is a closed shape that follows the shape of the positioning groove 31, which can define the vertical stacking state of the cutlery 3 in sequence and in a unified manner.

[0063] The tableware storage compartment 21 provided in this embodiment is adapted to accommodate plastic or wooden cutlery and spoons of conventional size (such as Fig.10 and Fig.11 As shown), the mold cavity size can also be changed according to customer needs to achieve multi-specification switching. In addition, the first guide plate 211 can be made of a transparent material to observe the number of tableware 3 and replenish it when the number is insufficient.

[0064] The tableware drop bin 22 has an upper mold 221, a middle mold 222 and a lower mold 223 arranged in sequence along the vertical direction, and is used for the tableware 3 to slide sequentially to the taking position of the lower mold 223, that is, the state where the tableware handle extends out of the bin mechanism.

[0065] The tableware storage bin 21 is disposed on the upper mold support platform 2212 of the upper mold 221, and its bottom is correspondingly connected to the upper mold channel 2211 to maintain communication. The upper mold channel 2211 has a certain height (such as Figure 5 As shown), part of the tableware 3 has fallen into the upper mold channel 2211 under the influence of gravity.

[0066] like Figure 4As shown, the middle mold 222 is placed in the bottom of the upper mold 221. The middle mold 222 is close to the thickness of the tableware, that is, the thickness is less than or equal to the thickness of the tableware 3, and can stably accommodate a single piece of tableware 3. It includes a middle mold bearing platform 2221 and a vertical plate 2222 arranged thereon. The middle bearing platform 2221 is provided with a middle mold channel 2223. The vertical plate 2222 is arranged at the rear end of the middle mold channel 2223. The vertical plate 2222 is provided with a fixing rod 2226 for installing a reset spring 2227 on one side facing the middle mold channel 2223; and the other side is connected to the rack 2244 of the linkage assembly 224. When the middle mold 222 is installed, the vertical plate 2222 is outside the rear side wall of the upper mold 221, and the reset spring 2227 abuts against the side wall to form a movable misalignment and reset space between the middle mold 222 and the upper mold 221.

[0067] It should be noted that the tail end of the middle mold channel 2223 is provided with a first buffer 2224, and the front end is provided with a second buffer 2225. When the tableware 3 is a spoon, since the spoon head has an arc structure, the second buffer 2225 can provide a buffer space for it to form a horizontal state, while compared with the table knife and fork, the second buffer 2225 is not a necessary setting. The first buffer 2224 also plays the same role, in order to keep the tableware 3 in a horizontal state, it can buffer the impact of the tableware.

[0068] The lower mold 223 is a split structure, having two relatively arranged mold bodies 2231 for forming a space for tableware to slide down. The mold body 2231 includes a lower mold supporting platform 2232 arranged at the upper end, a tableware sliding conveying cavity and an inclined slide 2239 at a tableware taking position.

[0069] Specifically, a lower mold channel 2233 is provided on the lower mold support platform 2232; a plurality of support rods 2234 arranged in a descending manner (similar to a step-like shape) are provided in the tableware sliding and conveying cavity of the lower mold 223, forming a slideway for the tableware 3 to slide obliquely, and the support rods 2234 are inserted into the fixing holes 2236 fixed on the side wall of the tableware sliding and conveying cavity. A limiting block 2235 for limiting the sliding of the head of the tableware is provided at the tail end of the tableware sliding and conveying cavity to prevent excessive sliding. Before the tableware 3 is taken out, its head is kept in the silo mechanism 2 to ensure the hygiene of the tableware 3. In the process of taking out the tableware 3, the limiting block 2235 can move to both sides to make room for the head of the tableware to pass through, and automatically reset under the elastic force.

[0070] Further, a space for installing the linkage assembly 224 is provided at the tableware taking position of the lower mold 223. The linkage assembly 224 includes a linkage rod 2241, and a first transmission member 2242 is provided at the upper part of the linkage rod 2241. The teeth on the first transmission member 2242 mesh with the gear 2243 provided on the middle mold bearing platform 2221, and transmit the transmission to the rack 2244 to push the vertical plate 2222 to move forward; a second transmission member 2245 and a third transmission member 2246 arranged opposite thereto are provided at the lower part of the linkage rod 2241, and meshing teeth are provided on the second transmission member 2245 and the third transmission member 2246, and a pusher 2247 is also provided at the lower part of the second transmission member 2245 and the third transmission member 2246, and the pusher 2247 can be a freely rotatable columnar component to reduce the friction between the tableware 3 and it. The push member 2247 is stuck in the two grooves of the cutlery head. When the cutlery head passes through, it directly pushes the push member 2247 to make an action similar to opening a door, that is, it drives the second transmission member 2245 and the third transmission member 2246 to rotate outward and open, forming a channel for taking out the cutlery 3, and taking out the cutlery 3.

[0071] The linkage assembly 224 constitutes a linkage switch for taking out tableware when it is not the first time to take out the tableware. When the last tableware is taken out, the rack 2244 pushes the vertical plate 2222 to move forward, so that the next tableware 3 falls into the middle mold 222 and is stuck on the offset platform and cannot fall.

[0072] In addition, in order to further ensure sanitary conditions, a dust cover 23 is also provided at the tableware taking position of the lower mold 223, including a dust cover body 231, a dust cover 232 and a tableware taking port 233 below. The dust cover body 231 is provided with a first switch hole 234 matching the first switch 236, and a second switch hole 235 matching the second switch 237. The side wall of the dust cover body 231 is provided with a positioning protrusion 238 that is fixedly engaged with the positioning groove 2238 provided on the side plate 2237 of the lower mold 223, so as to facilitate disassembly and maintenance. Among them, the first switch 236 is a starting switch in the initial state of the device, which is in contact with the rack 2244. Pushing the first switch 236 can drive the rack 2244 to move forward, and drive the middle mold 222 to move forward. The second switch 237 is a control switch for taking the silo mechanism 2 out of the housing 1. A holder 225 with a spring 226 is provided on the rear side of the lower mold 223 in contact with the wall of the housing 1. When the second switch 237 is pressed, the locking mechanism between the silo mechanism 2 and the housing 1 can be unlocked, and the holder 225 can be pushed out by the elastic force of the spring 226, so that the silo mechanism 2 can be taken out of the housing 1 (such as Figure 2 shown in the removed state).

[0073] Example 2

[0074] The present invention also provides a method for using the self-service tableware dispensing device, comprising the following steps:

[0075] S1, tableware loading stage

[0076] The operator stacks the same type of tableware 3 (such as spoons, knives or forks) in the same direction and puts them into the tableware storage bin 21. The first guide plate 211 and the second guide plate 212 help to restrict them to be arranged in the vertical direction. The tableware 3 naturally slides into the upper mold channel by gravity. According to the needs of the scene, one bin mechanism 2 or multiple bin mechanisms 2 can be selected. When there are multiple bin mechanisms 2, the same type of tableware 3 or different types of tableware 3 can be prevented.

[0077] S2. Initial blocking and temporary storage

[0078] like Figure 6 As shown, in the initial state, the middle mold 222 is aligned with the channel of the upper mold 221 and is misaligned with the channel of the lower mold 223 (as shown in FIG. Figure 7 As shown in FIG. 2 , the bottom tableware is limited by the misaligned structure and stays in the middle mold 222. Because the channels of the upper mold 221 and the middle mold 222 overlap, and the channels of the middle mold 222 and the lower mold 223 are misaligned, the tableware 3 is stuck on the misaligned platform and cannot fall.

[0079] S3, tableware release

[0080] When taking out the tableware for the first time, the user needs to press the first switch 236 linked to the middle mold 222 to turn it on, driving the rack 2244 to drive the vertical plate 2222 to push the middle mold 222, so that the middle mold 222 is aligned with the channel of the lower mold 223 and misaligned with the channel of the upper mold 221 (such as Figure 8 As shown in the figure, the tableware 3 falls into the lower mold 223 and slides down the delivery cavity to the taking position. At this time, the next tableware is stuck on the misaligned platform of the middle and upper molds and cannot fall. At this time, the reset spring 2227 rebounds quickly, so that all molds are reset to the initial state. Figure 7 In the state shown, the tableware falls into the middle mold 222 because the upper and middle molds overlap.

[0081] S4. Tableware in place

[0082] The tableware is guided by the support rod 2234 in the lower mold 223 and slides into the taking position provided with the limit block 2235. The handle part thereof extends out of the cover shell 1 for easy grasping, and the head of the tableware is fixed at the positioning position by the limit block.

[0083] S5, tableware removal and next piece in place

[0084] When the user pulls the cutlery handle to take out the cutlery, the cutlery head triggers the linkage assembly 224, which drives the middle mold 222 from being misaligned with the channel of the lower mold 223 to being aligned, so that the next cutlery automatically falls to the retrieval position, completing a retrieval cycle.

[0085] When it is not the first time to take out, there is no need to press the first switch 236 in step S3. The user only needs to pull the handle of the tableware 3 that has been in place to drive the linkage assembly 224 to reset and switch the dislocation structure between the molds, so that the next tableware 3 falls into the taking position, and then the next tableware 3 falls into the middle mold 222, completing the sequential delivery process.

[0086] During use, the dust cover 23 of the present invention remains closed, with only the handle extending out of the cover, so that the user's hand does not touch the head of the tableware, ensuring hygiene. The entire action is driven by the access trigger linkage structure, and the mold is automatically reset through the spring structure to complete the tableware distribution without the need for additional power. It has the advantages of single access, sequential supply, pollution prevention, and low maintenance cost, and is suitable for high-frequency use scenarios such as buffet restaurants, shared kitchens, and canteens.

[0087] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, a person of ordinary skill in the art should understand that any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
