Description

Technical Field

[0001] The utility model relates to the technical field of unmanned retail equipment, and in particular to a packaging device and a vending machine. Background Art

[0002] With the rapid development of social economy, people's pace of life is getting faster and faster. How to liberate people from the tedious daily kitchen work is a question that many people are interested in and have been thinking about. With the continuous development of automatic control technology, computer technology and network communication technology, intelligent, automated and unmanned catering equipment will be the future development trend.

[0003] Catering equipment on the market usually allows customers to pack their own food, or directly delivers the food to customers. Since the surface temperature of cooked food is high after heating, customers are easily scalded; therefore, automatically packing the food before output can prevent scalding problems. However, when multiple folded paper bags stored in traditional silos are output to the packaging platform, if the tension of the spring is used to press the paper bags to the output end, and the silo is set to an inclined state, the paper bags slide to the output end by gravity, which can easily lead to uncontrollable situations; that is, when there are a large number of paper bags stored in the silo, the paper bags are likely to automatically slide out of the silo, affecting the subsequent operation of the actuator.

[0026] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present utility model. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model. In this article, terms such as first, second, and third are only used to distinguish one entity from another entity, and do not require or imply any order or association between these entities.

[0027] In the market, catering equipment usually allows customers to pack meals by themselves or directly deliver the meals to customers. Since the surface temperature of cooked meals is high after heating, customers are likely to be scalded. When a customer's order contains multiple meals, the meals can only be served one by one. Moreover, it is impossible to confirm whether the order number and order content match the actual situation. Therefore, automatically packing and outputting the meals can prevent these problems. However, when multiple folded paper bags stored in a traditional bin are output to a packing platform, if the tension of a spring is used to press the paper bags towards the output end and the bin is set to an inclined state, the paper bags slide towards the output end by gravity, which easily leads to uncontrollable situations. That is, when there are a large number of paper bags stored in the bin, the paper bags are likely to slide out of the bin automatically, affecting the operation of subsequent actuators.

[0028] In view of this, a first aspect of the present utility model provides a packing device, as Figures 1-5 shown, including: a storage bin 311, a limiting component 320, and a pushing mechanism 330. The storage bin 311 is provided with a receiving cavity, and a plurality of folded packaging boxes 50 are arranged in the receiving cavity. An opening is provided on a first side surface of the storage bin 311, so that each folded packaging box 50 is output from the opening. The limiting component 320 is arranged at the opening, and the limiting component 320 abuts against the folded packaging box 50, so that the folded packaging box 50 does not slide out of the receiving cavity due to the action of an external force. The pushing mechanism 330 is arranged in the storage bin 311, and the pushing mechanism 330 is arranged opposite to the opening. The pushing mechanism 330 includes a first push plate 331 and a second push plate 332 that is parallel to and spaced from the first push plate 331. The side of the second push plate 332 facing away from the first push plate 331 contacts the folded packaging box 50. Among them, the first push plate 331 is configured to be able to move towards the opening, and the first push plate 331 can drive the second push plate 332 to move, so as to keep one side of the second push plate 332 in contact with the folded packaging box 50. The second push plate 332 is configured to be able to move relative to the first push plate 331 to apply a preset pressing force to the folded packaging box 50.

[0029] The packaging box 50 can be made of, for example, paper material or plastic material, and no excessive limitation is made here. For example, when the packaging box 50 is in an unfolded state, it can have a rectangular body structure; while in a stacked state, it can be folded into a plate-like structure. The mutual stacking of multiple packaging boxes 50 is based on the sequential stacking of multiple folded plate-like structures. At this time, more packaging boxes 50 can be stored in the storage bin 311 to improve space utilization.

[0030] The limiting component 320 may include, for example, a first stopper, a second stopper, and a dial. The first stopper may be disposed at the bottom of the storage bin 311, the second stoppers may be respectively disposed on the left and right sides of the storage bin 311, and the dial may be disposed at the top of the storage bin 311. The limiting component 320 may be disposed at the opening and may be located outside the storage bin 311; the second stopper may be a freely rotatable roller. When the negative pressure suction cup on the shaping mechanism pulls out the folded packaging box 50, the roller contacts the side surface of the packaging box 50, and the free rotation of the roller can reduce friction. The top of the storage bin 311 may be set to be open. When the packaging box 50 is placed in the storage bin 311, its opening faces upward, so that after the packaging box 50 is unfolded, its opening faces upward, facilitating the placement of the meal box 60 into the packaging box 50. In the embodiment of the present application, a notch portion is provided on the opening edge of the packaging box 50, and the notch portion is located on the front side surface of the packaging box 50. When placed normally, the dial extends into the notch portion and abuts against the inner wall of the packaging box 50. When the negative pressure suction cup on the shaping mechanism pulls out the folded packaging box 50, the dial plays a role in restricting the movement of the abutted inner wall. At this time, the side wall where the notch portion is located will be relatively pulled apart from the side wall pressed by the dial by a certain distance, and this process can realize the transformation of the packaging box 50 from the folded state to the unfolded state.

[0031] An elastic member 333 may be disposed between the first push plate 331 and the second push plate 332. The elastic member 333 may be a spring, for example. The second push plate 332 moves relative to the first push plate 331 under the action of the spring to keep one side of the second push plate 332 in contact with the folded packaging box 50, so as to apply a preset pressing force to the folded packaging box 50. As the folded packaging box 50 in the accommodation cavity decreases due to use, the first push plate 331 may move towards the opening, and at the same time, the first push plate 331 may drive the second push plate 332 to move together, so that one side of the second push plate 332 always remains in contact with the folded packaging box 50, thereby applying a pressing force within a certain range value to the folded packaging box 50. Therefore, by the first push plate 331 pushing the second push plate 332 and the second push plate 332 being pushed towards the folded packaging box 50 under the pre-tightening force of the spring, the folded packaging box 50 will be automatically pressed; the functions of the first stopper, the second stopper, and the dial are to prevent the folded packaging box 50 from coming out when being pressed. The pressing force may be set to be slightly less than the resistance of the limiting component 320. When the folded packaging box 50 is pulled out by the negative pressure suction cup on the shaping mechanism, it can be ensured that the folded packaging boxes 50 are taken out from the storage bin 311 one by one. In this way, in the embodiment of the present application, the folded packaging boxes 50 do not slide towards the output end relying on gravity, and uncontrollable situations caused by the large number of folded packaging boxes 50 in the storage bin 311 can be avoided.

[0032] In some embodiments, in order to make the second push plate 332 move more smoothly relative to the first push plate 331, the pushing mechanism 330 further includes: a guiding assembly for guiding the second push plate 332 when it moves relative to the first push plate 331. The guiding assembly is disposed at the four right angles near the first push plate 331 and the second push plate 332. The guiding assembly includes: a guiding sleeve 334 disposed on the first push plate 331; a guiding shaft 335, one end of the guiding shaft 335 is fixedly connected to the second push plate 332, the other end of the guiding shaft 335 passes through the guiding sleeve 334, and the guiding shaft 335 is slidably and cooperatively connected with the guiding sleeve 334. The elastic member 333 is a spring sleeved on the guiding shaft 335, and both ends of the spring contact the first push plate 331 and the second push plate 332 respectively. Specifically, a linear bearing may be provided in the guiding sleeve 334, and the linear bearing is adapted to the guiding shaft 335 to provide support and guiding movement for the guiding shaft 335. Springs may be sleeved on the two guiding shafts 335 below respectively. When the springs are in the initial state, that is, the springs can be slightly compressed to generate a certain pre-tightening force, and the pre-tightening force can be set to be less than the resistance force of the limiting assembly 320. At this time, a locking retaining ring may be provided at the end of the guiding shaft 335 to prevent the distance between the first push plate 331 and the second push plate 332 from becoming larger, so that one side of the second push plate 332 always remains in contact with the folded packaging box 50, thereby applying a constant pressing force to the folded packaging box 50, that is, the pressing force is the tension when the spring is compressed, and the pressing force is slightly less than the resistance force of the limiting assembly 320.

[0033] In some embodiments, the packing device further includes: a first transverse movement module 340, which is installed below the storage bin 311. The first transverse movement module 340 includes a second guide rail and a second transmission component. The second guide rail is slidably and cooperatively connected to the first push plate 331. The second transmission component is used to drive the first push plate 331 to move in the accommodation cavity. Specifically, a base can be provided at the bottom of the storage bin 311, and the first transverse movement module 340 can be installed on the base. A second slider can be provided at the bottom of the first push plate 331, and the second slider is slidably and cooperatively connected to the second guide rail. The second transmission component can include a lead screw, a nut adapted to the lead screw, and a driving motor. Among them, the lead screw is arranged parallel to the second guide rail, and the extending direction of the second guide rail can be set along the direction in which the folded packaging boxes 50 are stacked in sequence. The nut can be arranged at the bottom of the first push plate 331, and the driving motor is connected to the lead screw to drive the lead screw to rotate, thereby driving the first push plate 331 to slide along the second guide rail. A chute adapted to the size of the nut can be provided on the bottom plate of the storage bin 311, so that when the first push plate 331 moves to both ends in the accommodation cavity, it does not interfere with the bottom plate of the storage bin 311. In addition, limit switches can be provided at both ends of the storage bin 311 to detect when the first push plate 331 moves to both ends and control the driving motor to stop running. Moreover, a packaging box 50 detection switch can be installed at the bottom of the storage bin 311. When the switch detects that the number of folded packaging boxes 50 is small, it will send information to the system to prompt for timely replenishment.

[0034] In some embodiments, the packaging device further includes: a first detector 350, which includes a sensor 352 and a sensing member 351, the sensor 352 is installed on one of the first push plate 331 and the second push plate 332, and the sensing member 351 is installed on the other, and the first detector 350 is used to detect the distance between the first push plate 331 and the second push plate 332; wherein, when the folded packaging box 50 in the accommodating cavity is reduced due to use, the sensor is away from the sensing member, and the sensor does not detect a signal, the first transmission assembly is started to drive the first push plate 331 to move toward the folded packaging box 50; when the sensor is close to the sensing member and the sensor detects a signal, the first transmission assembly drives the first push plate 331 to move toward the folded packaging box 50 and stop, so as to control the preload force of the elastic member 333. Specifically, the sensor can be installed on the first push plate 331, and the induction element can be installed on the second push plate 332; wherein the sensor 352 can be set as a photoelectric sensor, for example, the photoelectric sensor can be set as a slot sensor, and the induction element 351 is inserted into the slot photoelectric center of the sensor 352, at which time the sensor can be triggered to send a detection signal, that is, the spring is in the initial state at this time; each time the negative pressure suction cup on the shaping mechanism pulls out a folded packaging box 50, the spring will rebound a distance of the folded packaging box 50, when the folded packaging box 50 is reduced due to use, the induction element is separated from the slot photoelectric center, and the sensor does not detect a signal, the spring is in the initial state, the drive motor is powered on and started forward, driving the first push plate 331 to approach the second push plate 332, at which time the spring is compressed, and the other side of the second push plate 332 presses the folded packaging box 50; when the slot photoelectric center senses the induction element again, the drive motor loses power and stops running, and this cycle repeats. Therefore, by setting the sensor and the induction element, the spacing between the first push plate 331 and the second push plate 332 can be reasonably and effectively controlled, so that the second push plate 332 can also be reasonably and effectively controlled to apply a constant pressing force to the folded packaging box 50. In addition, the first push plate 331 and the second push plate 332 can also be provided with a second detector 353, and the second detector 353 can include, for example, a micro switch, which can be provided on the first push plate 331, and a touch plate can be provided on the second push plate 332. When the micro switch contacts the touch plate, when the micro switch is touched, the device alarms, and the driving motor needs to stop urgently to prevent the spacing between the first push plate 331 and the second push plate 332 from being too small, causing the spring to be squeezed and fail, thereby causing the folded packaging box 50 to be uncontrollably pushed out of the storage bin 311. In the prior art, if the tension of the spring is used to press the paper bag to the output end, as the number of folded paper bags used decreases, the spring stretches, and its tension becomes smaller, which makes it difficult to pull the paper bag out.In the embodiment of the present application, as the folded packaging boxes in the storage bin are used less, the first push plate can move towards the folded packaging boxes at any time according to the usage situation. The first push plate drives the second push plate to move closer to the folded packaging boxes, and the second push plate moves relative to the first push plate towards the folded packaging boxes to press the folded packaging boxes; the pressing force can be set to be slightly less than the resistance of the limiting component. When the folded packaging boxes are pulled out by the negative pressure suction cups on the shaping mechanism, it can ensure that the folded packaging boxes are taken out of the storage bin one by one.

A clamping portion is provided on the robotic arm 363, and the clamping portion is used for clamping the meal box 60; the robotic arm 363 is configured to be able to lift up and down along the lifting main body 362; the bottom of the base frame 361 is fixedly connected to the top of the storage bin 311, and the base frame 361 extends along the direction of outputting the folded packaging box 50 from the opening; the top of the base frame 361 is fixedly connected to the bottom of the lifting main body 362; wherein, the clamping portion is located above the packaging position. Specifically, the clamping portion can clamp the protruding edge of the meal box 60; when the clamping portion moves downward, the cooked meal box 60 is put into the unfolded packaging box 50. The robotic arm 363 is slidably arranged on the lifting main body 362 in a vertically opposite direction. Through the sliding movement of the robotic arm 363 on the lifting main body 362, the clamping portion on the robotic arm 363 can move into or out of the space of the packaging box 50, thereby realizing the placement of the meal box 60.

A plurality of suction cups and a vacuum generator are arranged on the second side frame assembly 314, and the suction cups are connected to the vacuum generator, and the suction cups are arranged toward the packaging box 50 to be taken out. When the second side frame assembly 314 moves to the packaging box 50 in the storage bin 311, the packaging box 50 at the output end of the storage bin 311 can be adsorbed by the suction cup, and then the second side frame assembly 314 is controlled to move away from the storage bin 311, so as to take the packaging box 50 out of the storage bin 311 and put it on the conveying platform 312, and then the packaging box 50 is shaped and opened. When the unfolded packaging box 50 is located at the packaging position, the vacuum generating pump stops working, the air release valve is actuated, and the suction cup releases the packaging box.
