Description

Technical Field

[0001] The utility model relates to the field of vending machines, in particular to a goods delivery device. Background Art

[0002] An automatic vending machine can, according to the operation of a user, automatically push out goods through a goods delivery device after corresponding payment is completed. Some existing goods delivery devices include a machine base, a delivery table, a motor and a lead screw nut pair. The delivery table is movably arranged on the machine base in the left-right direction. The motor drives the delivery table to move left and right reciprocally through the lead screw nut pair. After the goods in the storage pipe enter the delivery table, the motor rotates forward to drive the delivery table to move left for delivering goods, and then the motor rotates reversely to drive the delivery table to move right for resetting to reload goods. During the process of forward and reverse rotation switching of the motor, it is necessary to go through the processes of motor deceleration, stop and re-acceleration, so that the left-right reciprocating movement period of the delivery table is relatively long and the delivery efficiency is relatively low. Content of the Utility Model

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a goods delivery device, which can make the left-right reciprocating movement period of the delivery table relatively short and improve the delivery efficiency.

The rotation driver is arranged on the transmission frame and is used to drive the driving wheel to rotate in one direction. The driving wheel is in contact and cooperation with the annular track. When the driving wheel rotates in one direction, a force in the direction of the linear velocity of the driving wheel is applied to the annular track to make the driving wheel move along the annular track, and the transmission frame is used to drive the delivery table to move left and right reciprocally relative to the machine base.

Since the central axis of the annular track is perpendicular to the left-right direction, the driving wheel will move along the annular track and sequentially pass through the left end and the right end of the annular track. The movement of the driving wheel relative to the annular track can be converted by the transmission frame to drive the delivery table to move left and right. During this period, since the rotation driver keeps rotating in one direction to make the driving wheel keep moving in one direction along the annular track, the rotation driver does not need to go through the processes of deceleration, stop, re-acceleration, etc., so that the left-right reciprocating movement period of the delivery table is relatively short and the delivery efficiency is improved.

[0034] In the description of the present utility model, unless otherwise clearly defined, words such as "set", "installed", "connected", etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0035] Refer to Figures 1 to 5 , which is a shipping device according to an embodiment of the present utility model, including a machine base 100, a shipping table 200, an annular track 300, and a driving mechanism 400. The shipping table 200 is movably disposed on the machine base 100 in the left-right direction; the annular track 300 is disposed on the shipping table 200, and the central axis of the annular track 300 is perpendicular to the left-right direction; the driving mechanism 400 is disposed on the machine base 100, and the driving mechanism 400 includes a driving wheel 410, a rotation driver 420, and a transmission frame 430. The driving wheel 410 is rotatably disposed on the transmission frame 430, the rotation driver 420 is disposed on the transmission frame 430 and is used to drive the driving wheel 410 to rotate unidirectionally. The driving wheel 410 is in contact and cooperation with the annular track 300. When the driving wheel 410 rotates unidirectionally, a force is applied to the annular track 300 along the linear velocity direction of the driving wheel 410 to cause the driving wheel 410 to move along the annular track 300, and the shipping table 200 is driven by the transmission frame 430 to reciprocate left and right relative to the machine base 100.

[0036] The driving wheel 410 rotates unidirectionally by rotating the driver 420. Since the central axis of the annular track 300 is perpendicular to the left - right direction, the driving wheel 410 will move along the annular track 300 and sequentially pass through the left end and the right end of the annular track 300. The movement of the driving wheel 410 relative to the annular track 300 can drive the shipping platform 200 to move left and right through the conversion of the transmission frame 430. During this period, since the rotating driver 420 keeps rotating unidirectionally to make the driving wheel 410 move unidirectionally along the annular track 300, the rotating driver 420 does not need to go through processes such as deceleration, stop, and re - acceleration, so that the left - right reciprocating movement period of the shipping platform 200 is shorter, improving the shipping efficiency.

[0037] In the embodiment, one end of the transmission frame 430 is pivotally connected to the machine base 100 and the rotation axis is parallel to the central axis of the annular track 300, and the driving wheel 410 is rotatably arranged at the other end of the transmission frame 430. The transmission frame 430 is similar to the function of a connecting rod, converting the circular motion of the driving wheel 410 along the annular track 300 into a linear motion of the shipping platform 200 along the left - right direction. The structure is simple and relatively convenient to use. It can be imagined that the transmission frame 430 can also be other structures. For example, one end of the transmission frame 430 is slidably arranged on the machine base 100, and its sliding direction is perpendicular to the left - right direction. By the way of the front - back sliding of the transmission frame 430, the driving force of the driving wheel 410 for the left - right movement of the shipping platform 200 is retained, so that the shipping platform 200 can move left and right.

[0038] In the embodiment, the annular track 300 is an annular rack, and the driving wheel 410 includes a first gear 411, and the first gear 411 meshes with the annular rack. The meshing of the first gear 411 with the annular rack enables the first gear 411 to move along the annular track 300 when rotating, and generates a large acting force between the two, so as to drive the shipping platform 200 to move relative to the machine base 100. The movement of the shipping platform 200 is relatively stable and the use effect is good. It can be imagined that the annular track 300 and the driving wheel 410 can also be other transmission methods. For example, the annular track 300 is an annular friction strip, and the driving wheel 410 is a friction wheel, and the friction wheel is in frictional cooperation with the annular friction strip. Through the way of contact friction, an interaction force is generated between the friction wheel and the annular track 300, so that the friction wheel can move along the annular track 300.

[0039] In the embodiment, a limiting block 210 is arranged on one side of the annular track 300. The limiting block 210 and the annular track 300 enclose an annular limiting space 500, and the driving wheel 410 is located in the annular limiting space 500. When the rotating driver 420 drives the driving wheel 410 to rotate, the limiting block 210 can keep the driving wheel 410 in contact with the annular track 300, so that the driving wheel 410 can continuously and stably move along the annular track 300 when rotating.

[0040] Specifically, when the driving wheel 410 moves from the left end to the right end of the annular track 300, the shipping platform 200 will move to the left; when the driving wheel 410 moves from the right end to the left end of the annular track 300, the shipping platform 200 will move to the right and reset.

[0041] In the embodiment, the annular track 300 is arranged around the outer periphery of the limiting block 210. The driving wheel 410 is provided with a rotating block 412 along the direction of the rotation axis. The rotating block 412 abuts against the limiting block 210, and the first gear 411 is offset from the limiting block 210 along the direction of the rotation axis. The driving wheel 410 abuts against the limiting block 210 through the rotating block 412, and the first gear 411 does not directly contact the limiting block 210, which can not only keep the first gear 411 meshed with the annular track 300, but also prevent the limiting block 210 from frictionally hindering the rotation of the first gear 411 and prevent the limiting block 210 from wearing the first gear 411. It can be imagined that in some other embodiments, it can also be that the limiting block 210 is arranged around the outside of the annular track 300 to form an annular limiting space 500.

[0042] Specifically, the transmission frame 430 is pivotally connected to the machine base 100 in the vertical direction, and the central axis of the annular track 300 is arranged in the vertical direction.

[0043] It can be imagined that in some other embodiments, the driving mechanism 400 can also be installed on the shipping platform 200. At this time, the transmission frame 430 is pivotally connected to the shipping platform 200, and the corresponding annular track 300 is arranged on the machine base 100 at this time. When the driving wheel 410 rotates unidirectionally, it can also move relative to the annular track 300, and then drive the shipping platform 200 to reciprocate left and right through the transmission frame 430. At this time, when the first gear 411 moves from the left end to the right end of the annular track 300, the shipping platform 200 moves to the right and resets; when the first gear 411 moves from the right end to the left end of the annular track 300, the shipping platform 200 moves to the left for shipping.

[0044] In an embodiment, the machine base 100 is provided with a sliding groove 110 in the left-right direction, the delivery table 200 is slidably arranged in the sliding groove 110, the machine base 100 is provided with a receiving cavity 120, the receiving cavity 120 is located below the sliding groove 110, the annular track 300 is arranged on the lower side of the delivery table 200, the transmission frame 430 is located in the receiving cavity 120, a communication hole 130 is opened between the bottom wall of the sliding groove 110 and the receiving cavity 120, and the rotation drive 420 is passed through the communication hole 130. By arranging the drive mechanism 400 and the transmission frame 430 in the receiving cavity 120 to protect and hide the drive mechanism 400 and the transmission frame 430, the influence of external dust and water vapor on the drive mechanism 400 and the transmission frame 430 can be reduced, and the drive mechanism 400 can normally drive the delivery table 200 to move left and right through the communication hole 130; the transmission frame 430 and the drive mechanism 400 are located below the delivery table 200, which is beneficial to arranging multiple delivery devices in the vending machine side by side in the front-rear direction, and the structure is compact and convenient to use.

[0045] It can be imagined that the delivery table 200 can also move left and right relative to the machine base 100 through other structures. For example, the machine base 100 is provided with a slide rail in the left-right direction, the delivery table 200 is provided with a slider, and the slider is slidably connected to the slide rail; or the machine base 100 is provided with a guide post in the left-right direction, the delivery table 200 is provided with a guide sleeve, and the guide post is slidably passed through the guide sleeve, etc.

[0046] Specifically, the rotation drive 420 includes a drive motor 421, a worm 422 and a second gear 423. The first gear 411 and the second gear 423 are coaxially arranged and rotate synchronously. The rotation axis of the first gear 411 is vertical, the rotation axis of the worm 422 is horizontal, and the worm 422 is in transmission cooperation with the second gear 423. When in use, the motor drives the worm 422 to rotate, and then drives the second gear 423 and the first gear 411 to rotate. The first gear 411 meshes with the annular rack to drive the delivery table 200 to reciprocate left and right.

[0047] It can be imagined that the rotation drive 420 can also be other structures. For example, the rotation drive 420 uses a reduction motor to directly drive the first gear 411 to rotate.

[0048] In the embodiment, the circular track 300 includes a left reversing section 310, a right reversing section 320 and two straight rail sections 330, the straight rail section 330 extends in the left-right direction, the two straight rail sections 330 are arranged side by side, the left ends of the two straight rail sections 330 are connected by the left reversing section 310, and the right ends of the two straight rail sections 330 are connected by the right reversing section 320. In the above circular track 300, when the driving wheel 410 moves to the straight rail section 330, the delivery platform 200 moves quickly to the left or right; when the driving wheel 410 is located at one of the straight rail sections 330, it can move to the other straight rail section 330 through the left reversing section 310 or the right reversing section 320, so that the delivery platform 200 changes direction. The circular track 300 with the above structure can make the delivery platform 200 have a larger left-right movement range and a faster conveying speed, which is conducive to the rapid transmission of goods and has better stability in cargo transportation.

[0049] It is conceivable that the circular track 300 can also be other shapes. As long as its central axis is perpendicular to the left and right directions, the circular track 300 has a left end and a right end. At this time, when the driving wheel 410 reciprocates between the left and right ends of the circular track 300, it can drive the shipping platform 200 to move left and right. For example, the circular track 300 can be a circular track, an elliptical track, a rounded polygonal track, etc., and technical personnel in this field can make specific configurations according to actual needs.

[0050] In the embodiment, the left reversing section 310 and the right reversing section 320 are semicircular, and the two ends of the left reversing section 310 are tangent to the two straight rail sections 330, and the two ends of the right reversing section 320 are tangent to the two straight rail sections 330. The left reversing section 310 and the right reversing section 320 are semicircular and tangent to the two straight rail sections 330, and the driving wheel 410 can be relatively smoothly reversed through the left reversing section 310 and the right reversing section 320, so that the rotation speed of the driving wheel 410 driven by the rotating driver 420 can be maintained at a high level, which is conducive to the rapid left-right reciprocating cyclic movement of the delivery platform 200.

[0051] Specifically, the annular track 300 is in the shape of a racetrack.

[0052] In the embodiment, the left side of the base 100 is the shipping side, and the shipping platform 200 includes a pallet 220 and a push block 230, wherein the push block 230 is disposed at the right end of the pallet 220, and the push block 230 is located on the upper side of the pallet 220. The goods to be shipped are directly placed on the pallet 220, and when the shipping platform 200 moves to the left, the pallet 220 supports the goods and moves to the left, and cooperates with the push block 230 to push the goods to the left, so that the shipping platform 200 can stably push the goods to the left, and the structure is simple and relatively easy to use.

[0053] In an embodiment, a storage pipe 600 is further included. The storage pipe 600 is arranged on the machine base 100 in the vertical direction, and the lower end of the storage pipe 600 is vertically opposite to the shipping platform 200. By providing the storage pipe 600, a certain number of goods can be arranged in the storage pipe 600 in the vertical direction. After the lowermost goods are shipped by the shipping platform 200, the upper goods can automatically fall to the shipping platform 200 under the action of gravity, providing a physical basis for automated continuous shipping, and having a simple structure and convenient use.

[0054] Specifically, the machine base 100 and the storage pipe 600 enclose a shipping opening 610, and the shipping opening 610 is located on the left side of the machine base 100 and the storage pipe 600.

[0055] It can be imagined that in other embodiments, the shipping platform 200 can also be other structures. For example, the shipping platform 200 is a pallet 220 or a push plate, and those skilled in the art can configure it specifically according to actual needs.

[0056] In an embodiment, a goods guiding surface 240 is provided on the upper side of the pushing block 230, and the height of the goods guiding surface 240 gradually decreases in the left-to-right direction. After the shipping platform 200 moves to the left, the goods in the storage pipe 600 will fall under the action of gravity, and sometimes it will interfere with the rightward reset of the shipping platform 200. Therefore, the goods guiding surface 240 is provided on the upper side of the pushing block 230. When the shipping platform 200 resets to the right, the goods guiding surface 240 can guide and lift the goods, so that the shipping platform 200 can be reset smoothly. Finally, new goods fall onto the pallet 220 again to complete the goods loading process.

[0057] Specifically, the goods guiding surface 240 is an inclined surface, which is relatively convenient to process. It can be imagined that the goods guiding surface 240 can also be other structures, such as a rounded surface or an arc surface, etc., and those skilled in the art can configure it specifically according to actual needs.

[0058] In an embodiment, a detection sensor 700 and a control module are further included. The detection sensor 700 is arranged on the machine base 100 and is used to detect the position of the shipping platform 200. The control module is electrically connected to the detection sensor 700 and the rotation driver 420 respectively. By providing the detection sensor 700 and the control module, the detection sensor 700 can detect the number of cyclic movements and the reset situation of the shipping platform 200. When the specified number of cycles is reached and the reset is completed, the control module can control the rotation driver 420 to stop working, so that the shipping device completes shipping, providing a physical basis for the automated control of the shipping device.

[0059] Specifically, the detection sensor 700 can be, for example, an optoelectronic sensor, a Hall sensor or a microswitch, etc., or other types of detection sensors 700, and those skilled in the art can configure it specifically according to actual needs.

[0060] Specifically, the control module can adopt a structure with control capabilities such as a circuit board, a single-chip microcomputer, or a microcomputer, etc., and those skilled in the art can specifically configure it according to actual needs.

[0061] In the description of this specification, the descriptions with reference to the terms "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples", etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention.
