Description

Technical Field

[0001] The utility model relates to the technical field of automatic vending machines, in particular to a material taking mechanism and a self-service pizza machine. Background Art

[0002] Self-service vending machines are commonly used equipment for commercial automation. They are not restricted by time and place, can save manpower and facilitate transactions. They are a new form of commercial retail, also known as 24-hour mini supermarkets. And with the changes in the market, vending machines have also appeared in various styles, including vending machines that sell pizza, etc.

[0003] The self-service pizza machine places the pizza in a pizza box and then puts it in a storage device for refrigeration or freezing, thereby maintaining the quality of the pizza for a long time. When in use, the pizza is taken out of the storage device by the transport device and sent to the heating device for heating. After heating, the pizza is sent to the delivery port.

[0004] The transport device of the existing self-service pizza machine mainly drives a material-taking pallet through a mounting seat to extend into the storage device and be placed at the bottom of the pizza box. After the pizza box is lifted up, it is withdrawn from the storage device and moved to the heating device, and then the pizza box is pushed into the heating device through a lever. The way the pallet and the lever cooperate to pick up the pizza box has poor stability. During the transport process, the pizza box is prone to shaking or sliding on the pallet, which may cause the pizza box to fall.

[0005] In view of this, it is necessary to propose a new technical solution to solve the above technical problems. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a material taking mechanism and a self-service pizza machine to solve the problems raised in the background technology.

[0007] In order to achieve the above-mentioned purpose, the utility model provides a first aspect of a material taking mechanism, including a mounting seat, a material taking frame slidably mounted on the mounting seat, and a driving mechanism for driving the material taking frame to open and close.

[0008] In a further technical solution, the material taking frame includes a mounting frame, a material supporting member and a material pressing member, the driving mechanism, the material supporting member and the material pressing member are respectively mounted on the mounting frame, and the driving mechanism drives the material supporting member and / or the material pressing member to open and close on the mounting frame. When taking materials, the distance between the material supporting member and the material pressing member is gradually reduced by the driving mechanism, thereby clamping the pizza box, and after the pizza box is sent into the heating area, the distance between the material supporting member and the material pressing member is gradually increased by the driving mechanism, thereby loosening the fixation of the pizza box.

[0009] In a further technical solution, a screw rod is included, the screw rod is mounted on the mounting frame, the output end of the driving mechanism is connected to the screw rod, the support piece and / or the pressing piece are respectively mounted on the screw rod, and the driving mechanism is used to drive the screw rod to rotate, so that the support piece and / or the pressing piece move up and down along the screw rod. The method of driving the support piece and / or the pressing piece to move by the rotation of the screw rod is more stable.

By setting the spring, when the driving mechanism drives the screw seat to move up and down, the spring squeezes the support piece and / or the pressing piece, causing them to be subjected to an inward force.

[0011] In a further technical solution, the support member and / or the pressing member are provided with an induction switch for sensing the position of the screw seat. By setting the induction switch, when the screw seat moves to the induction switch position, the driving mechanism stops working, and the support member and / or the pressing member limit the pizza box inwardly under the action of the spring, thereby completing the picking up of the pizza box.

[0012] In a further technical solution, a guide pin is arranged on the screw seat, and the guide pin and the screw seat respectively penetrate the support member and / or the pressing member.

[0038] Example 1

[0039] See Figure 1-5 As shown, the material taking mechanism includes a mounting seat, a material taking frame 1 is slidably mounted on the mounting seat, and the material taking frame 1 is provided with a driving mechanism 2 for driving the material taking frame 1 to open and close. The driving mechanism 2 drives the material taking frame 1 to open and close, so as to clamp the pizza box. This arrangement has strong stability and is not prone to shaking during transportation.

[0040] In a further specific embodiment, the material taking frame 1 includes a mounting frame 11, a material supporting member 12 and a material pressing member 13. The driving mechanism 2, the material supporting member 12 and the material pressing member 13 are respectively mounted on the mounting frame 11. As a preferred embodiment, the driving mechanism 2 of this embodiment drives the material pressing member 13 to open and close on the mounting frame 11. When taking materials, the material pressing member 13 is driven downward by the driving mechanism 2, so that the distance between the material supporting member 12 and the material pressing member 13 is gradually reduced, thereby clamping the pizza box. After the pizza box is sent into the heating area, the driving mechanism 2 drives the material pressing member 13 to move upward, so that the distance between the material supporting member 12 and the material pressing member 13 is gradually increased, thereby releasing the clamping of the pizza box, and then exiting the heating area.

[0041] In a further specific embodiment, a screw rod 3 is included, and the screw rod 3 is mounted on the mounting frame 11. The output end of the driving mechanism 2 is connected to the screw rod 3. As a preferred embodiment, the pressing piece 13 of this embodiment is mounted on the screw rod 3, and the supporting piece 12 is mounted on the mounting frame 11. The driving mechanism 2 is used to drive the screw rod 3 to rotate. When the screw rod 3 rotates, the pressing piece 13 moves up and down along the screw rod 3, thereby clamping and releasing the pizza box. It should be noted that according to actual use, this embodiment will add bearings at the upper and lower ends of the screw rod 3, respectively, so as to realize the rotation of the screw rod 3 relative to the mounting frame 11. The inner side of the bearing is sleeved on the screw rod 3, and the outer side of the bearing is mounted on the mounting frame 11. This setting further enhances the stability when clamping the pizza box.

[0042] In a further specific embodiment, at least one screw seat 4 is installed on the screw 3. As a preferred embodiment, the number of screw seats 4 in this embodiment is one. The pressing piece 13 in this embodiment is installed on the screw seat 4. The screw seat 4 is covered with a spring 5. The first end of the spring 5 abuts against the screw seat 4, and the second end of the spring 5 abuts against the pressing piece 13. By setting the spring 5, when the drive mechanism 2 drives the screw seat 4 to move downward to clamp the pizza box, the spring 5 contracts and squeezes the pressing piece 13, causing it to be subjected to a downward force. Through this setting, the force applied by the pressing piece 13 to the pizza box is mainly generated by the spring 5, avoiding the direct application of force to the pizza box by the drive mechanism 2. If the drive mechanism 2 directly applies force to the pizza box, the force applied by the drive mechanism 2 may be too large to crush the pizza box. If the force applied is too small, the pizza box may not be clamped and may fall. It should be noted that the pressing piece 13 in this embodiment uses a pressing plate, and the pressing plate can move up and down on the screw seat 4.

[0043] As a preferred embodiment, the presser 13 of this embodiment is provided with a sensing switch 131 for sensing the position of the screw seat 4. The screw seat 4 is provided with a guide pin 41, and the guide pin 41 and the screw seat 4 respectively penetrate the presser 13.

[0044] The guide pin 41 is provided to make the movement of the pressing piece 13 on the screw seat 4 smoother.

[0045] By setting the induction switch 131, when the screw seat 4 moves to the position of the induction switch 131, the driving mechanism 2 stops working, and the pressing member 13 limits the pizza box downward under the action of the spring 5, thereby cooperating with the supporting member 12 to complete the picking of the pizza box.

[0046] When the pressing piece 13 is in the initial state, it is squeezed by the spring 5 and is located at the lower end of the screw seat 4 and the guide pin 41. When the driving mechanism 2 drives the pressing piece 13 to touch the pizza box, the pressing piece 13 is stationary, and the screw seat 4 and the guide pin 41 continue to move downward under the drive of the driving mechanism 2. The pressing piece 13 gradually moves from the lower end to the upper end of the screw seat 4 and the guide pin 41, and the sensing point of the sensing switch 131 is getting closer and closer to the screw seat 4. When the sensing point of the sensing switch 131 senses the screw seat 4, the driving mechanism 2 stops running, and the pressing piece 13 and the supporting piece 12 complete the clamping of the pizza box.

[0047] At the same time, by setting the induction switch 131, the material taking mechanism of the utility model can adapt to the clamping of pizza boxes of various specifications, such as clamping pizza boxes of 10 cm, 15 cm, 20 cm or other thicknesses. If the induction switch 131 is not used, it is necessary to set in the program how long or how many turns the driving mechanism 2 rotates before stopping the operation. In this way, if it is necessary to clamp pizza boxes of different thicknesses, the program needs to be adjusted, which increases the debugging time and reduces the production efficiency.

[0048] In a further specific embodiment, the mounting frame 11 is provided with a guide column 111 and a guide seat 112, the guide seat 112 is slidably mounted on the guide column 111 up and down, and the pressing piece 13 is connected to the guide seat 112. The setting of the guide column 111 makes the movement of the pressing piece 13 smoother. It should be noted that when the driving mechanism 2 drives the pressing piece 13 downward to contact the pizza box, the positions of the pressing piece 13, the guide column 111 and the guide seat 112 are relatively stationary. The number of the guide columns 111 and the guide seat 112 in this embodiment is two groups, and they are respectively arranged on both sides of the pressing piece 13. In other specific embodiments, the number of the guide columns 111 and the guide seat 112 may also be only one group, three groups or four groups, which will not be repeated here.

[0049] In a further specific embodiment, the driving mechanism 2 includes a driving motor 21, a first transmission wheel 22, a second transmission wheel 23 and a transmission belt 24. The driving motor 21 is installed on the mounting frame 11. It should be noted that the driving motor 21 of this embodiment is installed on one side of the screw rod 3, which can reduce the overall height of the material-retrieving mechanism and save installation controls. The first transmission wheel 22 is sleeved on the output end of the driving motor 21, the second transmission wheel 23 is sleeved on the screw rod 3, and the transmission belt 24 is sleeved on the first transmission wheel 22 and the second transmission wheel 23. The driving motor 21 drives the screw rod 3 to rotate through the first transmission wheel 22, the second transmission wheel 23 and the transmission belt 24, thereby realizing the movement of the pressing piece 13, with a simple structure and strong stability.

[0050] In other specific embodiments, the driving mechanism 2 may also be only a driving motor 21 , and the output end of the driving motor 21 is directly connected to the screw rod 3 , so that the screw rod 3 is driven to rotate by the rotation of the driving motor 21 .

[0051] In another specific embodiment, the driving mechanism 2 may also include a driving motor 21, a first gear and a second gear, the output end of the driving motor 21 is connected to the first gear, the screw rod 3 is connected to the second gear, and the first gear is meshed with the second gear.

[0052] In a further specific embodiment, the mounting frame 11 is provided with a limiter 113 for limiting the position of the pizza box, and the limiter 113 is provided with a limit switch 114. When the pizza box is close to the limiter 113, the limiter 113 will limit the position of the pizza box. If the position of the pizza box is slightly offset, the limiter 113 will also adjust the position of the pizza box. The movement of the entire material-retrieving mechanism can be limited by the limit switch 114. When the transport device of the pizza machine drives the material-retrieving mechanism to clamp the pizza box in the storage device, the pizza box will touch the limit switch 114 before touching the limiter 113. When the limit switch 114 is touched, the limit switch 114 will transmit a signal to the control device, and the control device controls the transport device to stop moving forward, that is, the pizza machine stops the material-retrieving mechanism from moving forward. When the limit switch 114 touches the pizza box, it means that the clamping position of the pizza box has been reached, and the driving mechanism 2 can drive the pressing member 13 to clamp the pizza box.

[0053] It should be noted that the supporting member 12 of the present embodiment adopts a fork rod, and in other specific embodiments, the supporting member 12 may also adopt a supporting plate with the same structure as the pressing plate.

[0054] Example 2

[0055] The difference between this embodiment and embodiment 1 is that: "the driving mechanism 2 drives the supporting member 12 to open and close on the mounting frame 11; the supporting member 12 is installed on the screw rod 3; the supporting member 12 is installed on the screw rod seat 4; the second end of the spring 5 abuts against the supporting member 12; the guide pin 41 and the screw rod seat 4 respectively pass through the supporting member 12; the supporting member 12 is provided with a sensing switch 131 for sensing the position of the screw rod seat 4; the supporting member 12 is connected to the guide seat 112". Other details are not repeated here.

[0056] When in use, the handling device of the self-service pizza machine drives the material taking mechanism to extend into the storage device, and the material taking mechanism gradually approaches the pizza box, and makes the pizza box located between the material support 12 and the material pressing frame until the limit switch 114 touches the pizza box. When the limit switch 114 touches the pizza box, it means that the clamping position of the pizza box has been in place, at which time the driving mechanism 2 drives the screw 3 to rotate, and the screw 3 drives the material support 12 to move upward through the screw seat 4. When the material support 12 touches the pizza box, the material support 12 is relatively stationary, and the screw seat 4 continues to move upward until the induction switch 131 located on the material support 12 senses the screw seat 4, and then the screw seat 4 stops moving, and the material support 12 and the material pressing member 13 complete the clamping of the pizza box.

[0057] Example 3

[0058] See Figure 6 As shown, the difference between this embodiment and embodiment 1 is that: "the driving mechanism 2 drives the supporting piece 12 and the pressing piece 13 to open and close on the mounting frame 11; the supporting piece 12 and the pressing piece 13 are respectively installed on the screw 3; the number of the screw seats 4 is two, and the supporting piece 12 and the pressing piece 13 are respectively installed on one of the screw seats 4; the second end of the spring 5 of one of the screw seats 4 abuts against the supporting piece 12, and the second end of the spring 5 of the other screw seat 4 abuts against the pressing piece 13; one of the guide pins 41 and one of the screw seats 4 respectively penetrate the supporting piece 12, and the other of the guide pins 41 and the other of the screw seats 4 respectively penetrate the pressing piece 13; the pressing piece 13 and the supporting piece 12 are respectively provided with a sensing switch 131 for sensing the position of the screw seat 4; the supporting piece 12 and the pressing piece 13 are respectively connected to the guide seat 112". Other details are not repeated.

[0059] When in use, the handling device of the self-service pizza machine drives the material taking mechanism to extend into the storage device, and the material taking mechanism gradually approaches the pizza box, and makes the pizza box located between the material support 12 and the material pressing frame until the limit switch 114 touches the pizza box. When the limit switch 114 touches the pizza box, it means that the clamping position of the pizza box has been in place, and at this time, the driving mechanism 2 drives the screw rod 3 to rotate, and the screw rod 3 drives the material support 12 and the material pressing frame 13 to close in the middle through the two screw rod seats 4. When the material support 12 touches the pizza box, the material support 12 is relatively still, and when the material pressing frame 13 touches the pizza box, the material pressing frame 13 is relatively still, and the two screw rod seats 4 continue to close in the middle until the induction switch 131 located on the material support 12 or the material pressing frame 13 senses one of the screw rod seats 4, and then the two screw rod seats 4 stop moving, and the material support 12 and the material pressing frame 13 complete the clamping of the pizza box. Under the action of the spring 5, the supporting member 12 and the pressing member 13 apply a clamping force toward the center from both sides of the pizza box.

[0060] It should be noted that the induction switch 131 of this embodiment can be arranged on the material supporting member 12 or on the material pressing member 13 . As a preferred implementation, the induction switch 131 of this embodiment is arranged on the material pressing member 13 .
