Description

Technical Field

[0001] This utility model belongs to the field of catering equipment technology, specifically relating to a plate-separating device for dinner plates. Background Technology

[0002] In the catering service industry, canteens, and automated food processing, automated plate distribution is a key step in improving efficiency and reducing labor costs. Traditional plate distribution relies heavily on manual labor, which is inefficient and poses hygiene risks. Therefore, various automated plate distribution devices have emerged on the market. One common solution is to use pneumatic suction cups to directly grab the topmost plate, such as the automatic plate separation conveyor described in Chinese patent application number 201621296576.8, which uses a telescopic cylinder and vacuum suction cups to separate plates one by one. Another example is the automatic plate retrieval device described in Chinese patent application number 201920449007.X, which uses suction cup components to separate stacked plates one by one, thus enabling plate dispensing. However, for plates with smooth surfaces, tightly stacked surfaces, and no reliable gripping points at the edges, the aforementioned suction cups are prone to failure due to air leakage, resulting in unstable gripping and plates falling during transport, indicating poor reliability.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] like Figures 1 to 3 As shown, a plate-separating device for dinner plates includes a frame 1, a transmission mechanism 2, and a clamping mechanism 3. To more clearly demonstrate how the plate-separating device operates, in... Figures 1 to 6 Four plates were added to each plate.

[0019] The frame 1 is vertically arranged, and a horizontally arranged fixing plate 11 is installed on the frame 1 at the bottom. The fixing plate 11 has a square opening at its center, the size of which is determined by the size of the plate 4, and is slightly larger than the plate 4. This opening provides a path for the plate 4 released by the clamping mechanism 3 to fall. Casters 17 are provided at the bottom of the frame 1, allowing the plate-separating device to be moved to a designated position for operation as needed.

[0020] like Figure 4 and Figure 6As shown, the transmission mechanism 2 includes a drive motor 21, a surrounding synchronous belt 22, and multiple synchronous pulleys 23. The synchronous pulleys 23 are rotatably connected to the fixed plate 11 via bearings and are synchronously engaged by the synchronous belt 23. The output shaft of the drive motor 21 is selectively connected to either the synchronous belt 23 or any of the synchronous pulleys 23. Specifically, the output shaft of the drive motor 21 is coaxially connected to any of the synchronous pulleys 23 to directly drive all the synchronous pulleys 23 to rotate synchronously; or, the output shaft of the drive motor 21 engages with the synchronous belt 21 to indirectly drive all the synchronous pulleys 23 to rotate synchronously. In this embodiment, the output shaft of the drive motor 21 is connected to the synchronous belt 23.

[0021] The clamping mechanism 3 includes multiple vertically arranged screws 31, each screw 31 corresponding to a synchronous pulley 23 in one-to-one ratio, and the screws 31 are coaxially connected to their corresponding synchronous pulleys 23. The multiple screws 31 are arranged in a ring, and their threaded sections are used to rotate synchronously under the drive of the transmission mechanism 2 to jointly clamp or release the plate 4. Figures 7 to 9 As shown, the threaded section includes a clamping section 311 and a separating section 312. The clamping section 311 is located at the top of the threaded section and is used to clamp the plate 4; the separating section 312 is located at the bottom of the clamping section 311 and is used to separate the plate 4. When it is necessary to separate the plate 4, the screw 31 rotates, and the plate 4 at the bottom enters the separating section 312 from the clamping section 311, and then separates from the end of the separating section 312 under the action of the rotation of the screw 31. The plate 4 at the bottommost position is separated, and the plate 4 at the second to last position at the bottom is pressed onto the clamping section 311, and continues to enter the separating section 312 and separate under the action of the rotation of the screw 31. The subsequent operation steps of the plate 4 are as described above. The screw 31 and the synchronous pulley 23 are located on different sides of the fixed plate 11. In this embodiment, the synchronous pulley 23 is located at the top of the fixed plate 11, and the screw 31 is located at the bottom of the fixed plate 11.

[0022] In this embodiment, there are four synchronous pulleys 23, respectively located at the four corners of the opening. Therefore, the screws 31 under the synchronous pulleys 23 are used to clamp the four corners of the plate 4. A tensioning pulley 24 is rotatably connected to the fixing plate 11. The tensioning pulley 24 engages with the inner side of the synchronous belt 23 or abuts against the outer side, used to adjust the tension of the synchronous belt 23. In this embodiment, the tensioning pulley 24 abuts against the outer side of the synchronous belt 23. Multiple tensioning pulleys 24 are provided, rotatably connected to different positions on the fixing plate 11, and each tensioning pulley 24 abuts against the outer side of the synchronous belt 23. Figure 4 As shown, along the length of the plate 4, the outer side of the synchronous belt 23 on each side of the plate 4 abuts against two tensioning rollers 24. Along the width of the plate 4, the outer side of the synchronous belt 23 on the side of the plate 4 closest to the drive motor 21 abuts against two tensioning rollers 24.

[0023] A plurality of limit bars 12 are vertically installed on the frame 1, spaced apart within the inner region surrounded by the synchronous belt 22. Each limit bar 12 is connected to the edge of the opening in the fixing plate 11, and the bottom end of each limit bar 12 extends through the fixing plate 11 to the height of the bottom of the screw 31. The top end of each limit bar 12 extends upward, and the extension height can be set according to actual conditions. In this embodiment, six limit bars 12 are used, such as... Figure 4 As shown, along the length of the plate 4, two limiting strips 12 are installed at different positions along the edge of the opening on each side of the plate 4. Along the width of the plate 4, one limiting strip 12 is installed at the middle position along the edge of the opening on each side of the plate 4. These six limiting strips 12 are used to circumferentially limit the plate 4 during the plate-separation process. The limiting strips 12 are made of nylon, which is wear-resistant and prevents scratches on the plate 4.

[0024] In addition, such as Figures 3 to 6 As shown, the plate-dispensing device is also equipped with a first sensor 13 and a second sensor 14. The transmitter and receiver of the first sensor 13 are both mounted above the fixed plate 11 via a first bracket 15. The first bracket 15 is placed vertically, and its bottom is bolted to the fixed plate 11. The first sensor 13 monitors the amount of food in the plates 4 and issues a refill reminder when the amount of food in the plates 4 is insufficient. The transmitter and receiver of the second sensor 14 are both mounted below the fixed plate 11 via a second bracket 16. The second bracket 16 is placed vertically, and its top is bolted to the frame 1, as shown... Figure 1 and Figure 3 As shown, the second sensor 14 is used to monitor whether the plate 4 has been successfully separated from the screw 31. Both the first sensor 13 and the second sensor 14 are through-beam photoelectric sensors. Through-beam photoelectric sensors are existing technology and will not be described in detail here.

[0025] The operation steps of this plate-separating device are as follows: A stack of plates 4 are placed within the upper and lower space enclosed by the limiting strip 12. The four corners of the bottom plate 4 are pressed against the threaded section (i.e., the clamping section 311) of the screw 31. When a single plate 4 is needed, the drive motor 21 drives the synchronous belt 22 to rotate, which in turn drives all the synchronous pulleys 23 to rotate synchronously. The screw 31 at the bottom of the synchronous pulleys 23 also rotates synchronously. At this time, the bottom plate 4 enters the separating section 312 from the clamping section 311 and moves downward from the top of the separating section 312. When the plate 4 moves to the end of the separating section 312, the plate 4 is separated. The second sensor 14 will monitor whether the plate 4 has been successfully separated from the screw 31. The separation of other plates 4 is carried out in the same way as above, and will not be described in detail here. When the first sensor 13 detects that the number of plates 4 is insufficient, it issues a plate replenishment reminder.

[0026] The present embodiment has now been described in detail with reference to the accompanying drawings. Based on the above description, those skilled in the art should have a clear understanding of the present invention. Of course, the above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the content of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention and should be protected by the present invention.
