Description

Technical Field

[0001] The invention relates to a goods conveying device of an automatic vending machine platform. Background Art

[0002] At present, most vending machines rely on free fall to deliver goods. Some vending machines with lifting functions use the platform flipping structure after the goods fall to the receiving platform. When the receiving platform reaches the designated position, the flipping action causes the goods to fall into the pickup bin. Some receiving platforms are push-plate type. When the goods fall onto the receiving platform, the push plate of the receiving platform pushes the goods to the side of the box (there is a delivery port on the side), and the goods are pushed away from the receiving platform through the delivery port on the side of the box. Some receiving platforms are designed with a receiving box. After the goods fall onto the receiving box, the goods are sent to the side through a transmission mechanism, and the goods fall through the cooperation of the receiving box and the delivery port on the side of the box. In the process of goods falling on the above-mentioned receiving platforms, the flip-plate type needs to control the rotation angle through a motor when the receiving platform reaches the designated position, the push-plate type receiving platform needs a relatively wide synchronous belt, and the receiving box type receiving platform has a relatively complex design and control process, requiring multiple motors or mechanisms to achieve synchronization. The above delivery structures have high manufacturing costs, and the control process is relatively complex, which is prone to jamming.

[0003] Therefore, it is necessary to design a new cargo conveying device for a vending machine platform. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a goods conveying device for an automatic vending machine platform, which is easy to implement and can realize the conveying and dumping of goods.

[0005] The technical solution of the invention is as follows:

[0006] A cargo conveying device for a vending machine platform comprises a cargo loading mechanism and a driving mechanism;

[0007] The cargo loading mechanism comprises a dumping bucket seat (204) and a dumping bucket (200); the dumping bucket seat and the dumping bucket are hinged;

[0008] The tipping bucket is installed on the tipping bucket seat. The driving mechanism is used to drive the tipping bucket seat to move horizontally (such as horizontally or with a certain slope). After the tipping bucket seat moves to the set position, the tipping bucket tilts and the goods stored in the tipping bucket can be dumped out. If the rotation is large, the goods can be dumped out without the door body.

[0009] The driving mechanism is a synchronous sprocket-chain driving mechanism or a synchronous pulley-synchronous belt driving mechanism, and the tipping bucket seat is connected to the chain or synchronous belt. In the example, the bottom of the tipping bucket seat is connected to the synchronous belt through the synchronous belt connecting plate 208, thereby moving synchronously.

[0010] The front end of the dump box is provided with a door body (201); the cargo loading mechanism is provided with a door body locking mechanism; the cargo loading mechanism is provided with a door body unlocking mechanism, such as an electric unlocking mechanism, such as unlocking the door body locking mechanism by driving a motor.

[0011] The front end of the dump bucket is provided with a door body (201); the cargo loading mechanism is provided with a door body locking mechanism; and the cargo conveying device is provided with a door body unlocking mechanism.

[0012] The upper end of the door body is hinged to the upper end of the dump bucket, and the front end of the dump bucket seat is provided with a locking card plate (302) for clamping the lower end of the door body; a return torsion spring (301) is installed at the rotating shaft of the locking card plate; the door body unlocking mechanism is a shift lever fixed in the cargo conveying device, and when the dump bucket seat moves forward to the shift lever, the locking card plate rotates under the obstruction of the shift lever, thereby realizing the unlocking of the locking card plate and the door body.

[0013] The cargo conveying device is provided with a slide rail (100) for facilitating the horizontal movement of the tipping bucket seat, and a roller (205) is provided at the bottom or side of the tipping bucket seat.

[0014] The cargo loading mechanism is provided with a dumping limit mechanism for limiting the maximum dumping angle of the dump bucket; the dumping limit mechanism can be a gear-type dumping mechanism driven by a stepping motor, the motor drives the gear to rotate, and the gear rotates synchronously with the dump bucket.

[0015] The tipping limiting mechanism comprises a flip linkage plate (303);

[0016] The flip linkage plate is fixed on the tipping bucket, and an arc-shaped guide groove or guide hole is provided on the flip linkage plate; a clamping component is provided on the tipping bucket seat; the clamping component is a columnar component or a wheeled component; one end of the clamping component is clamped in the guide groove or guide hole. Since the length of the guide hole or guide groove is limited, the maximum angle at which the tipping bucket can rotate relative to the tipping bucket seat is determined.

[0017] The cargo conveying device is provided with a positioning sensor. The positioning sensor is a travel switch or a photoelectric sensor (108); the travel switch is preferably arranged on the slide rail; the photoelectric sensor cooperates with a reset light shielding sheet (206) on the dump seat.

[0018] The cargo conveying device is provided with an MCU, the driving mechanism is controlled by the MCU, and the positioning sensor is connected to the MCU. The MCU is used to control the driving mechanism to drive the cargo loading mechanism forward or backward and detect the starting position, etc.

[0019] The cargo delivery method comprises the following steps:

[0020] Step 1: Load the cargo at the starting position;

[0021] At the starting position, the cargo falls into the dump bucket, completing the loading of the cargo;

[0022] Step 2: Transport the goods to the unloading location;

[0023] Driven by the driving mechanism, the cargo loading mechanism moves forward until it moves to the unloading position; the cargo loading mechanism comprises a dump seat (204) and a dump bucket (200); the dump seat and the dump bucket are hinged;

[0024] Step 3: Dump the cargo out of the dump bucket at the unloading position;

[0025] At the unloading position, the bucket is tilted to pour out the goods in the bucket; (realizing the goods out of the warehouse)

[0026] Step 4: Reset;

[0027] After unloading is completed, the driving mechanism drives the cargo loading mechanism to move backward to the starting position, waiting for the next cargo loading.

[0028] Beneficial effects:

[0029] The goods conveying device of the vending machine platform of the present invention has the following characteristics:

[0030] (1) A new bucket device was designed. A bucket was set on the synchronous belt drive structure. After the bucket received the goods, the synchronous belt dragged the bucket forward and backward to realize the three actions of unlocking, flipping and locking the bucket again. This process eliminated the coordination relationship between the receiving platform and the side outlet of the box. It only needed to control the distance the bucket moved forward and backward. It involved few parts, had a simple structure and was easy to implement.

[0031] (2) It has a slide rail mechanism to facilitate smooth translation of the cargo installation mechanism;

[0032] The pulley is fixed on the dump seat (also called the moving slide) by bolts, and the dump seat is limited up and down and front and back through the pulleys arranged horizontally and vertically;

[0033] (3) It has a unique locking and unlocking mechanism. When a mechanical non-electric structure is adopted, it can be automatically locked and unlocked by wireless energy drive, and the structure is ingenious.

[0034] The transmission structure of the vending machine platform includes a synchronous belt transmission mechanism, a bucket and a locking mechanism. The locking mechanism is installed at the bottom of the bucket seat, and is connected to the locking card plate at one end of the rotating shaft seat and the flip linkage plate at the other end, wherein the reset torsion spring is installed on one side of the locking card plate, and the rotation angle of the locking card plate is realized through the rotating shaft seat; the bucket seat is connected to the bucket box body through a step screw to realize the function of a hinge (rotatable), and the upper end of the door body realizes the door body rotation using the same principle; the left and right mounting brackets and the slide rails are connected by screws to form the cargo receiving platform body, and the bucket seat can be realized to slide left and right after the bucket seat is installed; the left mounting bracket is installed with a driving motor, a motor bracket, and a driving pulley, etc., and the right mounting bracket is installed with a driven wheel seat and a driven wheel, etc., and the driving wheel and the driven wheel are linked through a synchronous belt; one end of the synchronous belt connecting plate is connected to the synchronous belt, and the other end is fixed to the bucket seat, so that the bucket seat can be controlled. The three states of bucket unlocking, flipping and re-locking are realized by dragging the bucket seat forward and backward through the synchronous belt; the flipping angle of the bucket is adjusted by the rotation radius of the flip linkage plate.

[0035] In summary, the present invention combines the advantages of the existing delivery platform, uses a driving motor, and realizes the three states of unlocking, flipping and re-locking when the synchronous belt moves right and left through different mechanical structure combinations; it greatly saves the manufacturing cost of the delivery platform, and at the same time realizes the three states of the tipping bucket by dragging the tipping bucket seat to move left and right through the synchronous belt, simplifies the design difficulty of the control process, avoids the unreliability of the cooperation between the receiving platform and the side delivery port of the box, and greatly improves the reliability of delivery. The cargo conveying device of this vending machine platform has a clever structure, is easy to implement, and runs smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0044] Example 1: Figures 1 to 5 A delivery structure of a vending machine platform includes a synchronous belt transmission mechanism, a cargo loading mechanism based on a dump bucket, and a locking mechanism.

[0046] The cargo loading mechanism comprises a dump box body (i.e., dump bucket), a dump seat, a door body and a synchronous belt connecting plate; an inwardly directed cargo guiding structure is designed on the upper edge of the dump box body.

[0047] The locking mechanism is composed of a rotating shaft seat, a locking card plate, a flip linkage plate and a reset torsion spring. The reset torsion spring is installed on one side of the locking card plate. The rotating shaft seat is used to install the locking card plate and the flip linkage plate.

[0048] When the synchronous belt drags the tipping bucket seat to move right and left, the tipping bucket is unlocked, flipped and locked again; the flipping angle of the tipping bucket is adjusted by the rotation radius of the flip linkage plate.

[0049] The delivery structure is composed of a synchronous belt transmission mechanism, a tipping bucket and a locking mechanism.

[0050] The synchronous belt transmission mechanism is composed of a drive motor, a code disc, a photoelectric sensor and a start position sensor, a motor bracket, a left mounting bracket, a right mounting bracket, a slide rail and a pulley, a driving wheel, a driven wheel and a driven wheel seat, a driving shaft, a driven wheel shaft and a synchronous belt.

[0051] The tipping bucket is composed of a tipping bucket box, a tipping bucket seat, a door body, a reset shading plate and a synchronous belt connecting plate;

[0052] The locking mechanism consists of a rotating shaft seat, a locking clamping plate, a flip linkage plate and a reset torsion spring.

[0053] The goods fall from the shelf to the tipping bucket. The tipping bucket is composed of a tipping bucket box body and a door body to form an open top box body. The door body pivot is above the tipping bucket box body, and the door body can be opened in a free state. In order to prevent the goods from falling into the tipping bucket with excessive impact and rushing out of the tipping bucket, a locking mechanism is designed to ensure that the goods are in the tipping bucket after they fall.

[0054] The pulley is fixed to the dump seat with bolts, and the dump seat is limited up and down and front and back through the pulleys arranged horizontally and vertically; the locking mechanism is installed at the lower part of the dump seat, and is connected to the locking card plate through one end of the rotating shaft seat and the other end is connected to the flip linkage plate, wherein the reset torsion spring is installed on one side of the locking card plate, and the rotation angle of the locking card plate is realized through the rotating shaft seat; the dump seat is connected to the dump box body through step screws to realize the rotation of the hinge, and the upper end of the door body realizes the rotation of the door body using the same principle; the left and right mounting brackets and slide rails are connected by screws to form the main body of the receiving platform, and the dump seat can be installed to slide left and right; the left mounting bracket is installed with a driving motor, a motor bracket, and a driving pulley, etc., and the right mounting bracket is installed with a driven wheel seat and a driven wheel, etc., and the driving wheel and the driven wheel are linked by a synchronous belt; one end of the synchronous belt connecting plate is connected to the synchronous belt, and the other end is fixed to the dump seat to realize the controllable dump seat.

[0055] Working principle:

[0056] After the flip box receives the goods, the driving motor drives the tipping seat to move right through the synchronous belt. When it reaches the set position (realized by the starting position sensor and the code disk), first, one end of the locking card plate touches the screw on one side of the driven wheel seat, and the locking card plate rotates to unlock the door body. The tipping seat continues to move right, and the flip linkage plate installed at the other end of the rotating shaft seat under the tipping seat contacts the other end of the driven wheel seat. During the right movement, the rotation of the flip plate linkage plate realizes the flipping of the tipping box body. When the flip box body reaches a certain angle, the goods are separated from the tipping bucket and fall off. The flipping angle of the tipping box body is adjusted by the rotation radius of the flip linkage plate. After the goods fall, the motor drives the synchronous belt to drag the tipping seat to the left, and the tipping bucket moves to the left at the same time. The linkage flap moves to the left and relies on gravity to reset. When the door body is reset under the action of gravity after a certain distance to the left, the locking card plate begins to break away from the screw constraint, resets under the action of the reset torsion spring, and locks the door body at the same time.

[0057] When the commodity falls into the tipping bucket 200, the driving motor 104 is activated, and the rotation of the driving pulley 102 is controlled through the starting position sensor 105, the code disc 101 and the photoelectric sensor 108, so that the movement of the synchronous belt 110 can be controlled;

[0058] A locking plate 302 is provided at the door body 201 on one side of the dump bucket 200 to prevent the door body from opening due to inertia when goods fall into the dump bucket;

[0059] During the delivery process, the synchronous belt and the dump seat 204 move together through the synchronous belt connecting plate

[0060] The tipping bucket seat 204, the pulley is fixed on the tipping bucket seat by bolts, and the tipping bucket seat is limited up and down and front and back through the pulleys arranged horizontally and vertically (refer to Figure 2 ); One end of the synchronous belt connecting plate 208 is installed on the dump seat 204, and the other end is fixed to the synchronous belt 110 by screws, so that when the synchronous belt 110 is driven, the dump seat 204 is driven to move forward and backward (refer to Figure 6 ), in order to reduce the resistance of the tipping seat 204 when it moves, pulleys are arranged in the horizontal and vertical directions of the tipping seat; when it reaches the specified position, the locking card plate 302 is about to contact the driven wheel seat 113, and the locking card plate 302 installed under the tipping seat 204 first contacts the screw on the driven wheel seat, and the locking card plate 302 rotates to unlock the door body 201, and the tipping seat 204 continues to move forward, and the locking card plate 302 touches the screw installed on the driven wheel seat 113 and starts to rotate. The screw limits the reset of the locking plate to ensure that the door body is opened. The flip linkage plate 303 contacts the other end of the driven wheel seat 113, and the tipping bucket 200 starts to flip. When it reaches the controlled angle, the goods fall, realizing a process of delivering goods;

[0061] The flip angle of the tipping bucket 200 is adjusted by the arc length of the arc groove or arc hole of the flip linkage plate 303; Description: By designing a series of flip linkage plates (different radii), a flip linkage plate with a suitable radius is selected according to different commodities. After the commodity falls, the driving motor 104 reverses, the synchronous belt 110 uses the synchronous belt connecting plate 208 to drag the tipping bucket seat to the left, and the tipping bucket box body 203 is reset under the action of gravity. When the door body 201 is also reset under the action of gravity, the reset torsion spring 301 acts to drive the locking card plate 302 to reset, so as to lock the door body 201. Then the synchronous belt 110 continues to drive, dragging the tipping bucket seat 204 and the tipping bucket 200 to continue to move backward. When reaching the starting position, the reset shading plate 206 blocks the photoelectric sensor 108, indicating that the starting position has been reached. The reset shading plate 206 cooperates with the photoelectric sensor 108 to complete a delivery process.
