Description

Technical Field

[0001] The utility model belongs to the technical field of automatic vending machines, and in particular relates to a delivery device and a shelf structure of an automatic vending machine. Background Art

[0002] There are two main ways for existing vending machines to deliver goods from the aisles when selling goods: 1. A reduction motor is installed at the end of each aisle of the vending machine to drive the spiral wire installed on the rotating chuck to rotate, so that the goods on the chuck can be pushed out one by one; 2. A conveyor belt is installed on each aisle, and the conveyor belt is driven by a stepper motor. The distance moved by the conveyor belt when pushing a product out can be controlled more accurately. As the conveyor belt moves, several goods are pushed out one by one.

[0003] In method 1, each cargo lane is independently set up and cannot share the same reduction motor. The reduction motor is easy to damage. The setting of multiple reduction motors not only increases the cost, but also increases the failure rate and reduces the stability of shipment. In addition, the wiring of so many reduction motors is inconvenient. Each reduction motor corresponds to a drive circuit, which is not conducive to the integration of the electronic control system. In method 2, the goods are driven by conveyor belts. The conveyor belts are prone to aging and have a short service life. The tightness needs to be adjusted regularly. The later maintenance is cumbersome, and the order of shipment is unstable.

[0004] In order to solve the above technical problems, there is a push-type delivery mechanism in the related technology, which can effectively solve the above technical problems. However, this technical solution has the problems of complex structure of the delivery mechanism, cumbersome delivery steps, and need to overcome great resistance when replenishing goods. Utility Model Content

[0005] The utility model aims to solve one of the technical problems in the related art at least to a certain extent. To this end,

[0006] According to an embodiment of the present disclosure, a delivery device of a vending machine is provided, which is arranged at the front end of a cargo channel for storing goods, and includes:

[0007] A delivery mechanism is arranged on both sides of the cargo channel, and the delivery mechanism includes a bracket and a limit assembly installed on the bracket;

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] The utility model provides a delivery device for a vending machine, which relates to the field of vending machines. The vending machine has a cargo channel inside, which is used to store goods. The delivery device is installed at the front end of the cargo channel to control the delivery of goods at the front end of the cargo channel to complete the vending action. Figures 1 to 24 The delivery device of the vending machine is described.

[0058] Please refer to Figure 1 , Figure 2 In an illustrative embodiment of a delivery device of an automatic vending machine of the utility model, the delivery device of the automatic vending machine includes a delivery mechanism 1 and a transmission mechanism 2.

[0059] The delivery mechanism 1 is disposed on both sides of the cargo channel. In this embodiment, two delivery mechanisms 1 are configured, and the two delivery mechanisms 1 are disposed on both sides of the cargo channel opposite to each other.

[0060] The delivery mechanism 1 may include a bracket 11, which is arranged at one side of the cargo channel. The bracket 11 is used to provide an installation space.

[0061] The delivery mechanism 1 may include a position limiting component, wherein the position limiting component is installed in the bracket 11 .

[0062] refer to Figure 3 The limiting assembly may include a limiting member 13 and a cargo support member 12 hinged to the limiting member 13. The limiting member 13 is closer to the front end of the cargo channel relative to the cargo support member 12.

[0063] The limiting member 13 is deformably arranged on the bracket 11 , the cargo supporting member 12 is hinged to the limiting member 13 , and the cargo supporting member 12 is movably arranged on the bracket 11 .

[0064] Specifically, refer to Figure 4 The front end of the cargo supporting member 12 is hinged to the limiting member 13 through the third pin 14, and the cargo supporting member 12 can move along the length direction of the cargo channel. The movement of the cargo supporting member 12 will cause the limiting member 13 to deform.

[0065] The limiting assembly may include a second torsion spring 16, which is sleeved on the third pin 14. One end of the second torsion spring 16 abuts against the cargo supporting member 12, and the other end of the second torsion spring 16 abuts against the limiting member 13, so that an obtuse angle is formed between the cargo supporting member 12 and the limiting member 13. The opening of the obtuse angle faces the cargo channel.

[0066] like Figure 7 As shown, it is a schematic diagram of the structure of the limit assembly on the left side of the cargo channel. Figure 8 As shown, it is a schematic diagram of the structure of the limiting component on the right side of the cargo aisle.

[0067] The transmission mechanism 2 is arranged at the bottom of the cargo channel, and the transmission mechanism 2 is connected with two limit assemblies. The two limit assemblies in the same delivery device act together under the action of the transmission mechanism 2 to complete the delivery of the goods in the cargo channel.

[0068] The transmission mechanism 2 has an initial state and a delivery state, and the delivery control of the goods is achieved by controlling the limit assembly.

[0069] Specifically, refer to Figure 5 When the transmission mechanism 2 is in the initial state, the limiting member 13 is triangular and protrudes toward the limiting member 13 on the opposite side, and the limiting member 13 abuts against the first product 7 near the front end of the cargo channel to support the first product 7; the supporting member 12 is located in the bracket 11 and is spaced apart from the cargo channel. That is, when the transmission mechanism 2 is in the initial state, the supporting member 12 does not enter the cargo channel.

[0070] refer to Figure 6 When the transmission mechanism 2 is in the shipping state, the limit member 13 is deformed to be close to the bracket 11, and the distance between the two limit members 13 is sufficient for the first product 7 to pass through. The supporting member 12 moves into the cargo channel and abuts against the second product 8 adjacent to the first product 7 to support the second product 8 and the products behind the second product 8.

[0071] In this embodiment, when the transmission mechanism 2 is in the delivery state, the limiting member 13 is deformed into the bracket to complete the delivery of the first product 7 .

[0072] That is to say, when the transmission mechanism 2 is in the initial state, the two limiters 13 can limit the passage of the first product 7; when the transmission mechanism 2 switches from the initial state to the delivery state, the limiters 13 are retracted. When the transmission mechanism 2 is in the delivery state, the distance between the two limiters 13 is enough for the first product 7 to pass through. At the same time, the supporting piece 12 moves to protrude toward the middle of the cargo channel, limiting the passage of the second product 8 next to the first product 7, so that orderly delivery can be achieved.

[0073] In this embodiment, the second torsion spring 16 plays a supporting and resetting role. Under the action of the second torsion spring 16, the obtuse angle formed between the cargo supporting member 12 and the limiting member 13 can always be maintained at one angle. In the initial state, it can be avoided to enter the cargo channel.

[0074] At the same time, when the goods are being shipped, that is, when the transmission mechanism 2 is in the shipping state, the obtuse angle (the first angle) can be increased, and the second torsion spring 16 can play a certain buffering role, and can also play a flexible supporting role between the goods, which is convenient for shipping. In addition, when replenishing goods, the supporting member 12 is subjected to a reverse force, and the obtuse angle between the supporting member 12 and the limiting member 13 can be increased, which is convenient for replenishing goods.

[0075] In some embodiments of the present application, the cargo supporting member 12 may include a cargo supporting baffle 121 and a supporting portion 122 .

[0076] The cargo support baffle 121 is hinged with the stopper 13 to form a first angle, and the cargo support baffle 121 is movably arranged on the bracket 11. A first angle is formed between the cargo support baffle 121 and the first delivery baffle 131, wherein the first angle is the above-mentioned obtuse angle.

[0077] When the transmission mechanism 2 is in the initial state, the cargo support baffle 121 and the support portion 122 are located in the bracket. In this embodiment, the cargo support baffle 121 is located in the bracket 11 and is parallel to the length direction of the cargo channel.

[0078] The support portion 122 is fixedly connected to the side of the cargo support baffle 121 away from the limiting member 13, and an angle is formed between the support portion 122 and the cargo support baffle 121. The angle is set at an obtuse angle and its opening faces away from the cargo support member 12 on the opposite side.

[0079] In this embodiment, the angle between the support portion 122 and the cargo support baffle 121 is: the angle between the side of the support portion 122 facing the opposite support portion 122 and the side of the cargo support baffle 121 facing the opposite cargo support baffle 121 .

[0080] In some embodiments of the present application, the side surface of the support portion 122 facing the opposite support portion 122 is arranged in an arc shape, and the arc-shaped opening of the support portion 122 faces away from the opposite support portion 122 .

[0081] Among them, reference Figure 7 The arc surface 123 of the supporting portion 122 may be an arc surface.

[0082] In this embodiment, by setting the side of the support part 122 toward the opposite side support part 122 to be arc-shaped, it is convenient to support the goods moving forward in the cargo channel, and at the same time, it can easily break away from the goods and exit the cargo channel. In addition, the arc surface 123 or the arc surface allows the support baffle to easily enter the gap between the goods, which is conducive to the cargo support 12 to break away from the squeezing force of the goods and exit the cargo channel more easily.

[0083] It should be noted that the angle between the support portion 122 and the cargo support baffle 121 is the angle between the outer side surface of the cargo support baffle 121 and the first plane, and the first plane is the plane where the free end and the connecting end of the side of the support portion 122 facing the opposite support portion 122 are located.

[0084] In some embodiments of the present application, the front end of the cargo support 12 is provided with an abutment portion 125, which is suitable for abutting against the limiter 13 to limit the minimum value of the obtuse angle. The cargo support 12 and the limiter 13 are hinged and rotated to increase the obtuse angle.

[0085] refer to Figure 8 The abutting portion 125 is disposed on the cargo supporting baffle 121, and the abutting portion 125 is located on the side of the cargo supporting baffle 121 facing the opposite cargo supporting baffle.

[0086] In this embodiment, the abutting portion 125 is provided to limit the minimum value of the obtuse angle so that the angle of the obtuse angle is not too small, that is, the obtuse angle value is prevented from being too small.

[0087] In some embodiments of the present application, reference Fig. 9 The support portion 122 is provided with a plurality of opening slots 124 spaced apart in the vertical direction.

[0088] In some embodiments of the present application, the front end of the limiting member 13 is rotatably connected to the bracket 11 via a second pin 134 .

[0089] In some embodiments of the present application, reference Figure 3 The first torsion spring 15 is sleeved on the second pin 134. One end of the first torsion spring 15 abuts against the bracket 11, and the other end abuts against the limiter 13, so that the limiter 13 protrudes toward the cargo channel.

[0090] In this embodiment, the first torsion spring 15 is provided to play a resetting role. When the transmission mechanism 2 is in the initial state, the first torsion spring 15 can keep the position of the first pin 133 protruding toward the inner side of the cargo channel.

[0091] The limiting member 13 includes a first delivery baffle 131 and a second delivery baffle 132 which are hinged to each other. The first delivery baffle 131 and the second delivery baffle 132 are hinged to each other through a first pin 133 .

[0092] In this embodiment, by setting a first shipping baffle 131 and a second shipping baffle 132 that are hinged to each other, the first shipping baffle 131 and the second shipping baffle 132 can rotate freely, so that the limiting member 13 can reciprocally protrude and withdraw into the cargo channel, which is convenient for supporting the first commodity 7 or providing for the shipping of the first commodity 7.

[0093] refer to Figure 4 , Figure 5 The second delivery baffle 132 is closer to the front end of the cargo channel relative to the first delivery baffle 131. The second delivery baffle 132 is rotatably connected to the bracket 11 through the second pin 134, so that the second delivery baffle 132 rotates relative to the second pin 134.

[0094] In some embodiments of the present application, reference Figure 3 The first torsion spring 15 is sleeved on the second pin 134. One end of the first torsion spring 15 abuts against the bracket 11, and the other end abuts against the second delivery baffle 132, so that the limiting member 13 protrudes into the cargo channel.

[0095] In some embodiments of the present application, a slide groove 111 extending along the length direction of the cargo channel is provided on the top and bottom ends of the bracket 11, and both ends of the third pin 14 are slidably connected in the two slide grooves 111 so that the third pin 14 can slide along the extension direction of the slide groove 111.

[0096] refer to Figure 5 When the transmission mechanism 2 is in the initial state, the third pin 14 is connected to the front end of the slide slot 111. Figure 6 When the transmission mechanism 2 is in the delivery state, the third pin 14 is connected to the rear end of the slide slot 111.

[0097] In this embodiment, the sliding groove 111 is provided to prevent the third pin 14 from tilting during the sliding process and affecting the delivery.

[0098] In some embodiments of the present application, the transmission mechanism 2 may include a base 21 and a push plate 22 .

[0099] refer to Figure 10 to Figure 14 The push plate 22 is slidably connected to the top of the base 21 along the length direction of the cargo channel. A push groove 225 is provided on the push plate 22, and the third pin 14 is penetrated in the push groove 225 and slidably connected with the push groove 225. The movement of the push plate 22 can drive the movement of the third pin 14.

[0100] In this embodiment, when the push plate 22 moves backward due to an external force, it can drive (push) the third pin shaft to move backward along the slide groove 111, thereby driving the two limit assemblies to move and completing the sale of the goods.

[0101] Among them, by providing the push groove 225, the third pin shaft can be driven to move backward when the push plate 22 moves backward, and the push groove 225 does not restrict the third pin 14 from moving backward by itself. In other words, when the third pin shaft moves backward, the push plate 22 does not need to move with it, reducing the thrust force that needs to be overcome for replenishment, making replenishment easier.

[0102] In some embodiments of the present application, a guide column 211 is provided on the base 21, and a guide groove 221 for the guide column 211 to pass through is provided on the push plate 22. The guide groove 221 is slidably connected to the guide column 211.

[0103] The guide slot 221 is extended along the length direction of the cargo channel. The guide post 211 is inserted into the guide post 211 and is slidably connected with the guide post 211 so that the guide post 211 moves relative to the guide slot 221 .

[0104] In this embodiment, the sliding cooperation between the guide groove 221 and the guide column 211 allows the push plate 22 to move in a straight line, thereby avoiding being impacted by forces in other directions and improving the sliding stability.

[0105] In some other embodiments, when the transmission mechanism 2 is in the initial state, the guide column 211 may be connected to the rear end of the guide groove 221 .

[0106] In some embodiments of the present application, a slideway 212 extending along the length direction of the cargo channel is provided on the base 21 , and a sliding portion 222 is provided on the push plate 22 , and the sliding portion 222 is slidably connected to the slideway 212 .

[0107] refer to Fig.11 An elastic reset member 23 abuts against the sliding portion 222 and a first side wall of the slideway 212 away from the sliding portion 222 .

[0108] Specifically, one end of the elastic reset member 23 abuts against the sliding portion 222, and the other end of the elastic reset member 23 abuts against the first side wall of the slideway 212 away from the sliding portion 222. The initial elastic force of the elastic reset member 23 pushes against the push plate 22 to keep the transmission mechanism 2 in the initial state.

[0109] Specifically, the push plate 22 and the base 21 are connected by an elastic reset member 23 . The elastic reset member 23 has a certain initial compression amount, and its corresponding elastic force provides a forward pushing force for the push plate 22 to ensure the initial state of the transmission mechanism 2 .

[0110] In this embodiment, the elastic reset member 23 is provided so that the push plate 22 pushes against and compresses the elastic reset member 23 when it moves backward under the external force. When the push plate 22 loses the external force for moving backward, the push plate 22 automatically resets under the action of the elastic reset member 23, that is, the compression elastic force of the elastic reset member 23 pushes the push plate 22 to move forward and return to the initial state.

[0111] In some embodiments of the present application, a support column 224 is provided on the sliding portion 222 , wherein the support column 224 is provided for the elastic reset member 23 to be mounted thereon.

[0112] Specifically, refer to Fig.12 The support column 224 is extended along the sliding direction of the push plate 22, and the elastic reset member 23 is sleeved on the outside of the support column 224 so that the elastic reset member 23 is compressed or elongated in the extension direction of the support column 224, that is, the axial direction.

[0113] The first side wall is provided with a through hole 213 for the support column 224 to pass through, and one end of the elastic reset member 23 abuts against the periphery of the through hole 213; this arrangement enables the elastic reset member 23 to stably abut between the sliding portion 222 and the first side wall.

[0114] In this embodiment, by providing a support column 224, the elastic reset member 23 is sleeved on the support column 224 to improve the stable support capacity. In addition, the support column 224 can play a guiding role, so that the elastic reset member 23 can be compressed or reset in a straight line direction.

[0115] In some embodiments of the present application, a notch is provided at the front end of the slideway 212, so that the slideway 111 has a U-shaped groove structure. Fig.12 , a U-shaped groove is formed in the middle of the base 21.

[0116] The bottom of the push plate 22 is provided with a stopper 223. When the push plate 22 moves backward, the stopper 223 is adapted to be connected with the notch.

[0117] Specifically, the push plate 22 is moved toward the rear end of the cargo channel (moves backward) by the external force, driving the stopper 223 to move in the gap. When the stopper 223 moves to connect with the bottom wall of the slideway 212, the transmission mechanism 2 is in the delivery state.

[0118] In some embodiments of the present application, an extension portion 135 is extended from the bottom of the limiting member 13 , and the extension portion 135 is sleeved on the outside of the third pin 14 .

[0119] refer to Fig. 9 , Fig.14 The extension part 135 is arranged at the bottom end of the first delivery baffle 131. The extension part 135 and the first delivery baffle 131 can be arranged integrally. The extension part 135 is sleeved on the outside of the third pin 14, and the extension part 135 and the third pin 14 rotate relative to each other.

[0120] By providing an extension portion 135 at the bottom of the first delivery baffle 131, the structural strength of the third pin 14 is enhanced, and the third pin 14 is prevented from being deformed when the push plate 22 moves backward to push the third pin 14, thereby improving the structural stability of the delivery device.

[0121] In some embodiments of the present application, a relief groove 112 is provided on the bracket 11. The relief groove 112 allows the extension portion 135 to move.

[0122] In this embodiment, the avoidance groove 112 is provided to prevent the bracket 11 from interfering with the movement of the extension portion 135, thereby preventing the deformation of the limiting member 13 and improving the shipping reliability.

[0123] The utility model also provides a shelf structure 10 of an automatic vending machine, which relates to the field of automatic vending machines. Figures 15 to 17 The shelf structure 10 of the vending machine will be described.

[0124] refer to Fig.15In an illustrative embodiment of the shelf structure 10 of the vending machine of the utility model, the shelf structure 10 of the vending machine may include a cargo channel bottom plate 3 and a delivery device of the vending machine described in any of the above technical solutions.

[0125] The cargo channel is located above the cargo channel bottom plate 3, and the delivery device is installed on the cargo channel bottom plate 3. The bracket 11 in the delivery device is installed on the cargo channel bottom plate 3, and the base 21 in the delivery device is installed on the cargo channel bottom plate 3.

[0126] The shelf structure 10 provided by the technical solution includes the delivery device in any of the above technical solutions, which plays a certain buffering role during delivery and facilitates delivery. In addition, when the supporting member 12 is subjected to a reverse force, the angle between the supporting member 12 and the limiting member 13 can be increased, which facilitates replenishment.

[0127] In some embodiments of the present application, continue to refer to Fig.15 The shelf structure 10 of the vending machine may include an aisle frame 6. The aisle frame 6 is connected to the aisle bottom plate 3. In this embodiment, the aisle frame 6 is detachably connected to the aisle bottom plate 3.

[0128] In some embodiments of the present application, the shelf structure 10 of the vending machine may include a plurality of shelves. The plurality of shelves are arranged in parallel and at intervals on the aisle frame 6. The shelves extend along the front-to-back direction of the vending machine, and one end of the shelf in the length direction is connected to the bracket 11 in the delivery device.

[0129] In some embodiments of the present application, the shelf structure 10 of the vending machine may include a cargo aisle slide rail 4 having a plurality of rollers. The cargo aisle slide rail 4 is disposed between adjacent partitions.

[0130] Continue to refer Fig.15 The cargo channel slideway 212 is installed on the cargo channel frame 6 and the cargo channel bottom plate 3. The cargo channel slideway 4 and the partitions on both sides thereof are enclosed to form a cargo channel for storing goods.

[0131] In this embodiment, a cargo aisle slide rail 4 with a plurality of rollers is provided so that the goods in the cargo aisle can slide forward more easily.

[0132] In some embodiments of the present application, reference Fig.16 The cargo channel slide rail 4 has a storage section and a delivery section 5, and the delivery section 5 forms the front end of the cargo channel slide rail 4. The delivery section 5 is arranged to be tilted downward from the back to the front. The angle between the delivery section 5 and the horizontal plane can be set according to actual needs.

[0133] In this embodiment, reference Fig.17By setting the delivery section 5, during the delivery process of the first product 7, after the first product 7 is freed from the obstruction of the first delivery baffle 131, it is easier for the first product 7 to reach the designated pickup port, thereby facilitating delivery.

[0134] In some embodiments of the present application, in two adjacent delivery devices, two adjacent limit assemblies are installed in the same bracket 11. This arrangement allows one bracket 11 to be omitted between adjacent cargo lanes, saving material costs.

[0135] In some embodiments of the present application, a plurality of open slots 124 are arranged at intervals on the support portion 122. When the transmission mechanism 2 is in an initial state, two support portions 122 in the same bracket 11 can be arranged crosswise through the open slots 124.

[0136] In this embodiment, one end of the support portion 122 hinged to the first delivery baffle 131 is a connection end, and the other end is a free end. The opening groove 124 is formed by the free end of the support portion 122 being recessed toward the connection end.

[0137] In this embodiment, by setting the opening groove 124, the two support parts 122 in the same bracket 11 can be cross-set through the opening groove 124, which can reduce the width space of the bracket 11 and increase the number of cargo lanes on the same shelf to a certain extent.

[0138] It can be understood that, in this embodiment, the opening slots 124 on the left and right supporting parts 122 in the same delivery device are staggered.

[0139] In order to further understand the technical solution of this embodiment, refer to Figure 5-6 , Figure 18 to Figure 24 The working principle of the shipping device is described in detail.

[0140] refer to Figure 5 , the transmission mechanism 2 is in the initial state, and the goods in the cargo channel have a tendency to move forward under the action of gravity (not limited to gravity but also including the elastic push plate 22), and are stationary in the cargo channel under the joint action of the two first delivery baffles 131. In this state, the first goods 7 form a self-locking force on the two first delivery baffles 131, which can well support the first goods 7 in the cargo channel.

[0141] like Fig.18As shown, when it is necessary to ship, the push plate 22 moves backward under the action of external force, and the push groove 225 of the push plate 22 pushes the third pin 14 on the shipping mechanism 1 on the left and right sides to move backward along the slide groove 111, thereby driving the two first shipping baffles 131 to move backward, so that the hinged positions of the first shipping baffles 131 and the second shipping baffles 132 in the two shipping mechanisms 1 withdraw from the cargo channel, that is, the limiter 13 is deformed to be close to the bracket 11, and the first cargo 7 and the second cargo 8 move forward synchronously. At the same time, the cargo supporting members 12 on the left and right sides enter the cargo channel. Among them, the cargo supporting members 12 on both sides can enter the cargo channel under the action of the second torsion spring 16, ready to support the second cargo 8.

[0142] like Figure 6 As shown, the cargo support 12 completely enters the cargo channel, and the curved second cargo 8 on the cargo support 12 abuts against it, completely supporting the second cargo 8 and the cargo behind it. At this time, the first cargo 7 is completely free of restraint, and the distance between the limiters 13 on the left and right sides is enough for the first cargo 7 to pass through. The first cargo 7 continues to move forward under the action of its own gravity and inertia to complete the shipment.

[0143] like Fig.19 As shown, the push plate 22 loses the external force and moves forward, and the third pins 14 on the delivery mechanisms 1 on both sides also lose the support force of the push groove 225. The second delivery baffle 132 rotates relative to the second pin 134 under the action of the first torsion spring 15, and the hinge position of the front end of the first delivery baffle 131 and the second delivery baffle 132, that is, the first pin 133, enters the cargo channel. At the same time, the third pins 14 at the rear ends of the two first delivery baffles 131 move forward along the slide 111. The cargo support members 12 on the left and right sides exit the cargo channel under the abutment between the cargo support members 12 and the first delivery baffle 131, and the second cargo 8 moves forward.

[0144] like Fig. 20 , the two limit assemblies return to their initial positions, the second product 8 moves forward, and contacts the first delivery baffles 131 on both sides of the aisle, so that the second product 8 and the subsequent products stay stably in the aisle, completing the delivery.

[0145] like Fig.21 As shown, the remaining goods 92 are placed in the aisle. When replenishment is needed, the newly added goods 91 are replenished to the aisle from the front end of the aisle. Fig.21 As shown, the direction of the arrows is the movement trend direction of each component during replenishment.

[0146] like Fig. 22As shown, when replenishing, the newly added goods 91 abut against the second delivery baffles 132 on both sides of the cargo channel, and the hinged positions of the front end of the first delivery baffle 131 and the rear end of the second delivery baffle 132 withdraw from the cargo channel. At the same time, the third pins 14 on both sides move backward along the slide groove 111. Among them, the cargo support 12 can enter the cargo channel under the action of the second torsion spring 16. Since the obtuse angle between the cargo support 12 and the first delivery baffle 131 is abutted by the abutment 125, the angle cannot be reduced, but can be increased in the opposite direction. The newly added goods 91 push the remaining goods 92 to move backward, and the remaining goods 92 abut against the cargo support 12, pushing the cargo support 12 out of the cargo channel. Ensure that the remaining goods 92 can move freely backward.

[0147] like Fig.23 As shown, the remaining goods 92 move backwards together with the newly added goods 91, and when the center of the newly added goods 91 exceeds the position of the first pin 133, the newly added goods 91 begin to contact the first delivery baffles 131 on both sides. The second delivery baffle 132 can rotate under the action of the first torsion spring 15, and the position where the first pin 133 is hinged enters the cargo channel, and the third pin 14 slides forward along the slide slot 111.

[0148] like Fig.24 As shown, the limit assemblies on both sides return to their initial positions, the newly added goods 91 and the remaining goods 92 slide forward under the action of their own gravity (not limited to gravity), the newly added goods 91 abut against the first delivery baffles 131 on both sides, and the replenishment is completed.

[0149] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0150] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
