Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and specifically to a cold storage. Background Art

[0002] At present, cold storage is a type of refrigeration equipment, which refers to the use of artificial means to create an environment with different temperature or humidity from the outdoor temperature, and is mainly used for the storage and access of some refrigerated goods.

[0003] Existing cold storages are usually rectangular chamber structures, with an opening and closing door on one side of the cold storage to facilitate loading and unloading of goods. When goods are placed in the cold storage, they need to be placed reasonably (for example, different categories of goods need to be placed in different areas, and the same category of goods need to be placed in strict order of production date) to facilitate the storage and retrieval of goods; however, this reasonable placement method is difficult to operate in practice, and it is easy for goods to be placed incorrectly; in addition, a passage for people and goods to walk needs to be reserved in the cold storage, that is, at least one passage along its length or width must be set up in the cold storage, and the space utilization rate is low.

[0004] Therefore, how to improve the existing cold storage to overcome the above-mentioned shortcomings is a problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] One purpose of the present application is to provide a cold storage with an ingenious layout, easy use, convenient for reasonable placement of goods, and high space utilization.

[0006] To achieve the above objectives, the technical solution adopted in the present application is: a cold storage, comprising a cold storage body, a front end of which is provided with an openable and closable opening; the cold storage also comprises at least one storage mechanism, each of which comprises a support frame and at least one storage component; each of the support frames is arranged inside the cold storage body at intervals along the left-right direction, and each of the storage components on the same storage mechanism is arranged at intervals along the up-down direction on the corresponding support frame; each of the storage components comprises a feeding track, a transfer track and a removal track, and the feeding track, the transfer track and the removal track are all arranged on the support frame; the feeding track is used to transport the item boxes to be refrigerated from front to back in sequence to the transfer track, the transfer track is used to transport the item boxes in sequence to the removal track, and the removal track is used to transport the item boxes in sequence from back to front.

[0007] Preferably, the feed track is located directly above or below the retrieval track, and the transfer track is arranged to be raised and lowered behind the feed track and the retrieval track; when the transfer track is raised and lowered to align with the feed track, the feed track is used to transport a single item box to the transfer track, until the transfer track is raised and lowered to align with the retrieval track, the transfer track is used to transport the single item box to the retrieval track. The advantages are: the layout of arranging the feed track directly above or below the retrieval track is more compact and reasonable, and the item box can be transported from the feed track to the retrieval track by controlling the raising and lowering of the transfer track, which is convenient to control.

[0008] Preferably, the feeding track is tilted downwardly and backwardly, so that the item box on the feeding track automatically slides backwardly under the action of gravity; the storage assembly also includes a first stopper, which is arranged at the rear end of the feeding track, and the first stopper is used to limit the item box on the feeding track from leaving the feeding track. The advantage is that when the feeding track is tilted downwardly and backwardly, when the item box is placed on the feeding track, the item box will slide backwardly along the feeding track under the action of its own gravity, so that no power source is required. In addition, under the action of the first stopper, when the item box slides to the rear end of the feed track, the first stopper starts to work, thereby limiting the item box from continuing to slide backward and preventing the item box from sliding off; when the transfer track is raised or lowered to be aligned with the feed track, the first stopper is controlled to stop working until the feed track is raised or lowered onto the transfer track, and one of the item boxes at the rear end of the feed track completely slides onto the transfer track, at which time the first stopper starts to work again and continues to prevent the item box on the feed track from sliding off.

[0009] Preferably, the first stopper comprises a first shell, a first baffle and a first driving member; the first shell is arranged on the support frame, and the first baffle is telescopically arranged on the first shell; the first driving member is arranged on the first shell, and the first driving member is used to drive the first baffle to extend or retract; when the first baffle is extended, the item box on the feeding track is restricted from leaving the feeding track. The advantage is that when the transfer track is raised and lowered to align with the feeding track, the first baffle is driven to retract by the first driving member, thereby releasing the restriction on the item box, and then the last item box on the feeding track automatically slides to the transfer track under the action of gravity, until the item box completely slides to the transfer track, the first baffle is driven to extend by the first driving member, thereby blocking the last item box on the feeding track from continuing to slide backward, thereby preventing the item box from sliding off.

[0010] Preferably, the retrieval track is tilted forward and downward, so that the item box on the retrieval track automatically slides forward under the action of gravity; the storage assembly also includes a second stopper, which is arranged at the front end of the retrieval track, and the second stopper is used to limit the item box on the retrieval track from leaving the retrieval track. The advantage is that when the retrieval track is tilted forward and downward, when the item box moves from the transfer track to the retrieval track, the item box will automatically slide forward along the retrieval track under the action of its own gravity, so that no power source is required. In addition, under the action of the second stopper, when the item box slides to the front end of the retrieval track, the second stopper starts to work, thereby limiting the item box from continuing to slide forward and preventing the item box from slipping; when the item box needs to be taken out, the second stopper is controlled to stop working so as to take out the item box at the front end of the retrieval track.

[0011] Preferably, the second stopper includes a second shell, a second baffle and a second drive member; the second shell is arranged on the support frame, and the second baffle is telescopically arranged on the second shell; the second drive member is arranged on the second shell, and the second drive member is used to drive the second baffle to extend or retract; when the second baffle is extended, the item box at the rear end of the removal track is restricted from detaching from the removal track. The advantage is that when the second baffle is extended by the second drive member, the second baffle can block the item box at the front end of the removal track from continuing to slide forward, thereby preventing the item box from sliding off; when the second baffle is retracted by the second drive member, the item box at the front end of the removal track can automatically slide forward under the action of gravity, which is convenient for removal.

[0012] Preferably, the transfer rail includes a lifting frame and a transfer frame, the lifting frame can be lifted and disposed on the supporting frame, and the rear end of the lifting frame is provided with a material baffle plate upward; the front end of the transfer frame is rotatably disposed on the lifting frame, and the rotation axis of the transfer frame is arranged along the left and right direction; when the transfer frame follows the lifting frame to be lifted and aligned with the feeding rail, the transfer frame rotates counterclockwise, so that the transfer frame is tilted backward and downward, and then the object box on the feeding rail automatically slides backward to the transfer frame, until the object box is completely moved onto the transfer frame, and the material baffle plate is used to limit the object box from continuing to slide backward; when the transfer frame follows the lifting frame to be lifted and aligned with the removal rail, the transfer frame rotates clockwise, so that the transfer frame is tilted forward and downward, and then the object box on the transfer frame automatically slides forward to the removal rail. The utility model has the advantages that: since the front end of the transfer rack is rotatably arranged on the lifting rack, and the rotation axis of the transfer rack is arranged in the left and right direction, when the transfer rack follows the lifting rack to be lifted and aligned with the feeding track, the transfer rack is controlled to rotate counterclockwise, so that the transfer rack is tilted to the rear and lower sides, and then the object box on the feeding track automatically slides backward to the transfer rack under the action of gravity; in addition, under the blocking action of the baffle plate, the object box sliding from the feeding track to the transfer rack will not slide from the rear end of the transfer rack, and in the process of lifting and lowering the lifting rack, the transfer rack and the object box on the transfer rack are both in a state of tilting backward and downward, so the object box on the transfer rack will not slide from the front end of the transfer rack; when the transfer rack follows the lifting rack to be aligned with the taking-out track, the transfer rack is controlled to rotate instantaneously clockwise, so that the transfer rack is tilted to the front and lower sides, and then the object box on the transfer rack automatically slides forward to the taking-out track under the action of gravity.

[0013] Preferably, the rear end of the lifting frame is provided with an arc groove, and the axis of the arc groove coincides with the rotation axis of the transfer frame; a limit block is provided on the left and / or right side of the rear end of the transfer frame, and the limit block is slidably connected to the arc groove. The advantage is that the sliding cooperation between the arc groove and the limit block can limit the rotation of the transfer frame, thereby improving the rotation accuracy of the transfer frame.

[0014] Preferably, the feeding track is located directly above the taking-out track; the storage assembly also includes an upper clamping member and a lower supporting member, and the upper clamping member and the lower supporting member are both arranged on the supporting frame; when the transfer frame rises to be aligned with the feeding track, the upper clamping member is used to force the limit block to slide to the lower end of the arc groove, so that the transfer frame is automatically tilted backward and downward; when the transfer frame descends to be aligned with the taking-out track, the lower supporting member is used to force the limit block to slide to the upper end of the arc groove, so that the transfer frame is automatically tilted forward and downward. The advantage is that when the transfer frame follows the lifting frame to move upward, until the limit block contacts the upper pressing member, the limit block (that is, the rear end of the transfer frame) cannot continue to move upward, and at this time, the lifting frame and the front end of the transfer frame can continue to move upward, until the limit block slides downward to the lower end of the arc groove relative to the lifting frame, and the lifting frame cannot continue to move upward, at this time, the transfer frame is just aligned with the rear end of the feeding rail, and the transfer frame is tilted backward and downward; when the transfer frame follows the lifting frame to move downward, until the transfer frame contacts the lower supporting member, the rear end of the transfer frame (that is, the limit block) cannot continue to move downward, and at this time, the lifting frame and the front end of the transfer frame can continue to move downward, until the limit block slides upward to the upper end of the arc groove relative to the lifting frame, and the lifting frame cannot continue to move downward, at this time, the transfer frame is just aligned with the rear end of the taking-out rail, and the transfer frame is tilted forward and downward. It can be seen from the above content that the automatic rotation of the front end of the transfer rack is achieved through the coordinated use of the upper pressing member and the lower supporting member, thereby eliminating the need to provide a separate power source.

[0015] Preferably, the storage assembly also includes a starting member, which includes a fixed pulley, a connecting rope and a counterweight, wherein the fixed pulley is rotatably arranged on the support frame; one end of the connecting rope is connected to the lifting frame, and the other end of the connecting rope is connected to the counterweight after passing around at least one of the fixed pulleys; when the item box slides completely onto the transfer frame, the lifting frame automatically descends and drives the counterweight to rise, until the item box on the transfer frame slides completely onto the removal track, and the counterweight automatically descends, thereby forcing the lifting frame to automatically rise. The utility model has the advantages that when there is no article box on the transfer rack, under the gravity of the counterweight block, the counterweight block pulls the lifting rack to slide upward automatically through the connecting rope, so that the lifting rack automatically rises, until the limit block slides to the lower end of the arc groove, the lifting rack stops rising, at this time, the transfer rack is just aligned with the rear end of the feeding track, and the transfer rack is tilted backward and downward, so that the article box at the last end of the feeding track automatically slides onto the transfer rack; when the article box completely slides onto the transfer rack, due to the increase of the weight of the article box, the lifting rack automatically descends, and at the same time drives the counterweight block to rise, until the limit block slides to the upper end of the arc groove, the lifting rack stops descending, at this time, the transfer rack is just aligned with the rear end of the taking-out track, and the transfer rack is tilted forward and downward, so that the article box on the transfer rack automatically slides onto the taking-out track. In addition, by increasing or decreasing the number of the counterweight blocks, or adjusting the weight of a single counterweight block, the automatic transportation of the article boxes of different weights can be satisfied.

[0016] Preferably, the storage assembly further comprises a limit frame, which is arranged on the support frame and is used to limit the horizontal shaking of the counterweight block. The advantage is that by being arranged on the limit frame, the counterweight block can be limited to prevent the counterweight block from shaking horizontally during the lifting process; otherwise, once the counterweight block shakes horizontally, it is easy to interfere with the movement of the item box and the lifting and lowering of the lifting frame.

[0017] Preferably, the transfer rack and / or the delivery track and / or the removal track are unpowered roller conveyors. The advantage is that the unpowered roller conveyor does not need to provide a separate power source and can reduce the running resistance of the object box on the transfer rack, the delivery track and the removal track.

[0018] Compared with the prior art, the beneficial effects of the present application are: (1) when the cold storage is storing items (i.e., the item boxes), the opening is first opened, and the item boxes are moved to the feed track in sequence, so that the item boxes are transported to the transfer track in sequence through the feed track in sequence; then, the item boxes are transported to the retrieval track in sequence through the transfer track; finally, the item boxes are transported forward in sequence through the retrieval track, so that the stored item boxes are arranged backward in sequence along the front end of the retrieval track until the entire retrieval track is filled, and the transfer track stops working, so that the item boxes are then arranged forward in sequence along the rear end of the feed track, and at the same time, the transfer track can also be used to temporarily store the item boxes, so that the storage of the item boxes is achieved through the retrieval track, the transfer track and the feed track. When the item box needs to be taken out, the opening is opened first, and then the item box is taken out from the front end of the take-out track in sequence. When the item box at the front end of the take-out track is taken away, the transfer track restarts to work, thereby continuing to add the item box at the rear end of the delivery track to the take-out track in sequence. From the above content, it can be seen that when storing and retrieving items in the cold storage, the staff only needs to stand at the opening to operate, which is more convenient to use, and there is no need to reserve a passage inside the cold storage, so the space utilization rate is higher.

[0019] (2) When storing the item boxes, in order to avoid mixing up the items, the item boxes containing the same type of items are stored in the same storage component, so that the corresponding number of storage components can be selected according to the type of items actually stored to meet the needs of item classification. In addition, since the item boxes stored first arrive at the front end of the removal track first, the item boxes with earlier production / packaging dates are stored first according to the production / packaging dates of the items in the item boxes, so that the item boxes with earlier production / packaging dates can be taken out first when taking out. From the above content, it can be seen that when storing items, the cold storage can strictly arrange the items in a reasonable manner according to the order of the types of items and the production / packaging dates.

[0040] Reference Figure 1One embodiment of the present application provides a cold storage, including a cold storage body 1, a front end of the cold storage body 1 is provided with an openable and closable opening 11, the opening and closing method of the opening 11 is the existing technology, for example, by setting a door panel to open and close the opening 11. The cold storage also includes at least one storage mechanism 2, each storage mechanism 2 includes a support frame 21 and at least one storage assembly 22; Figure 2 As shown, each support frame 21 is arranged inside the cold storage body 1 at intervals along the left-right direction, and each storage component 22 on the same storage mechanism 2 is arranged at intervals along the up-down direction on the corresponding support frame 21; each storage component 22 includes a feeding track 221, a transfer track 222 and a removal track 223, and the feeding track 221, the transfer track 222 and the removal track 223 are all arranged on the support frame 21; the feeding track 221 is used to transport the object boxes 3 to be refrigerated from front to back in sequence to the transfer track 222, the transfer track 222 is used to transport the object boxes 3 to the removal track 223 in sequence, and the removal track 223 is used to transport the object boxes 3 from back to front in sequence.

[0041] like Figure 1 and Figure 2 As shown, when the cold storage is storing items (i.e., the item boxes 3), the opening 11 is first opened, and the item boxes 3 are moved to the feeding track 221 in sequence, so that the item boxes 3 are transported to the transfer track 222 in sequence through the feeding track 221; then, the item boxes 3 are transported to the retrieval track 223 in sequence through the transfer track 222; finally, the item boxes 3 are transported forward in sequence through the retrieval track 223, so that the stored item boxes 3 are arranged backward in sequence along the front end of the retrieval track 223, until the entire retrieval track 223 is filled, and the transfer track 222 stops working, so that the item boxes 3 are then arranged forward in sequence along the rear end of the feeding track 221, and the transfer track 222 can also be used for temporary storage of the item boxes 3, so that the storage of the item boxes 3 is achieved through the retrieval track 223, the transfer track 222 and the feeding track 221. When it is necessary to take out the object box 3, the opening 11 is opened first, and then the object boxes 3 are taken out from the front end of the take-out track 223 in sequence. When the object box 3 at the front end of the take-out track 223 is taken away, the transfer track 222 restarts to work, thereby continuing to add the object boxes 3 at the rear end of the delivery track 221 to the take-out track 223 in sequence. It can be seen from the above content that when storing and retrieving objects in the cold storage, the staff only needs to stand at the opening 11 to operate, which is more convenient to use, and there is no need to reserve a passage inside the cold storage, so the space utilization rate is higher.

[0042] In addition, when storing the item boxes 3, in order to avoid mixing up the items, the item boxes 3 containing the same type of items are stored on the same storage component 22, so that the corresponding number of storage components 22 can be selected according to the type of items actually stored to meet the needs of item classification. In addition, since the item boxes 3 stored first arrive at the front end of the removal track 223 first, the item boxes 3 with earlier production / packaging dates are stored first according to the production / packaging dates of the items in the item boxes 3, so that the item boxes 3 with earlier production / packaging dates can be taken out first when taking out. From the above content, it can be seen that when storing items, the cold storage can reasonably place the items strictly according to the type of items and the order of production / packaging dates.

[0043] Reference Figure 2 In this embodiment, the feeding track 221 is located directly above the removal track 223 (or the feeding track 221 is located directly below the removal track 223, which is not shown in the drawings), and the transfer track 222 is arranged to be raised and lowered behind the feeding track 221 and the removal track 223; when the transfer track 222 is raised and lowered to align with the feeding track 221, the feeding track 221 is used to transport a single object box 3 to the transfer track 222, until the transfer track 222 is raised and lowered to align with the removal track 223, the transfer track 222 is used to transport the single object box 3 to the removal track 223. The layout of arranging the feeding track 221 directly above or below the removal track 223 is more compact and reasonable, and by controlling the raising and lowering of the transfer track 222, the object box 3 can be transported from the feeding track 221 to the removal track 223, which is convenient to control.

[0044] Reference Fig.15 In this embodiment, the feeding track 221 is tilted downward and backward, so that the object box 3 on the feeding track 221 automatically slides backward under the action of gravity; Figure 4As shown, the storage assembly 22 further includes a first stopper 224, which is disposed at the rear end of the feeding track 221 and is used to limit the object box 3 on the feeding track 221 from leaving the feeding track 221. When the feeding track 221 is tilted downward and backward, when the object box 3 is placed in the feeding track 221, the object box 3 will slide backward along the feeding track 221 under the action of its own gravity, thereby eliminating the need for a power source. In addition, under the action of the first stopper 224, when the item box 3 slides to the rear end of the feed track 221, the first stopper 224 starts to work, thereby limiting the item box 3 from continuing to slide backward and preventing the item box 3 from sliding off; when the transfer track 222 is raised or lowered to be aligned with the feed track 221, the first stopper 224 is controlled to stop working until the feed track 221 is raised or lowered to the transfer track 222, and the item box 3 at the rear end of the feed track 221 completely slides onto the transfer track 222, at which time the first stopper 224 starts to work again and continues to prevent the item box 3 on the feed track 221 from sliding off.

[0045] Reference Figure 5 as well as Figure 6 In this embodiment, the first stopper 224 includes a first shell 2241, a first baffle 2242 and a first driving member; the first shell 2241 is arranged on the support frame 21, and the first baffle 2242 is telescopically arranged on the first shell 2241; the first driving member is arranged on the first shell 2241, and the first driving member is used to drive the first baffle 2242 to extend or retract; when the first baffle 2242 is extended, it is possible to limit the item box 3 on the feeding track 221 from leaving the feeding track 221. When the transfer track 222 is raised and lowered to align with the feed track 221, the first baffle 2242 is driven to retract by the first drive member, thereby releasing the restriction on the item box 3, and the last item box 3 on the feed track 221 automatically slides onto the transfer track 222 under the action of gravity, until the item box 3 completely slides onto the transfer track 222, and the first baffle 2242 is driven to extend by the first drive member, thereby blocking the last item box 3 on the feed track 221 from continuing to slide backward, thereby preventing the item box 3 from sliding off. It should be noted that the present application does not limit the specific structure of the first drive member, for example, it can be a telescopic drive structure such as a cylinder, an oil cylinder, an electric telescopic rod, or a telescopic drive structure such as a telescopic rod. Figure 6 As shown, it includes a first electromagnet 2243 and a first spring 2244. The first spring 2244 forces the first baffle 2242 to automatically extend. When the first electromagnet 2243 is started, the magnetic force generated by the first electromagnet 2243 attracts the first baffle 2242 to automatically retract.

[0046] Reference Fig.15In this embodiment, the take-out track 223 is tilted forward and downward, so that the article box 3 on the take-out track 223 automatically slides forward under the action of gravity; Figure 7 As shown, the storage assembly 22 further includes a second stopper 225, which is arranged at the front end of the take-out track 223, and is used to limit the object box 3 on the take-out track 223 from being separated from the take-out track 223. When the take-out track 223 is arranged to be tilted forward and downward, when the object box 3 moves from the transfer track 222 to the take-out track 223, the object box 3 will automatically slide forward along the take-out track 223 under the action of its own gravity, so that no power source is provided. In addition, under the action of the second stopper 225, when the object box 3 slides to the front end of the take-out track 223, the second stopper 225 starts to work, thereby limiting the object box 3 from continuing to slide forward and preventing the object box 3 from slipping; when the object box 3 needs to be taken out, the second stopper 225 is controlled to stop working so that the object box 3 can be taken out from the front end of the take-out track 223.

[0047] Reference Figure 8 as well as Fig. 9 In this embodiment, the second stopper 225 includes a second housing 2251, a second baffle 2252 and a second driving member; the second housing 2251 is disposed on the support frame 21, and the second baffle 2252 is telescopically disposed on the second housing 2251; the second driving member is disposed on the second housing 2251, and the second driving member is used to drive the second baffle 2252 to extend or retract; when the second baffle 2252 is extended, the object box 3 at the rear end of the removal track 223 is restricted from being separated from the removal track 223. When the second baffle 2252 is extended by the second driving member, the second baffle 2252 is able to block the object box 3 at the front end of the removal track 223 from continuing to slide forward, thereby preventing the object box 3 from sliding off; when the second baffle 2252 is driven to retract by the second driving member, the object box 3 at the front end of the removal track 223 is able to automatically slide forward under the action of gravity, so as to facilitate removal. It should be noted that the present application does not limit the specific structure of the second driving member, for example, it can be a telescopic driving structure such as a cylinder, an oil cylinder, an electric telescopic rod, etc. Figure 6 As shown, it includes a second electromagnet 2253 and a second spring 2254. The second spring 2254 forces the second baffle 2252 to automatically extend. When the second electromagnet 2253 is activated, the magnetic force generated by the second electromagnet 2253 attracts the second baffle 2252 to automatically retract.

[0048] Reference Fig.10 as well as Fig.11In this embodiment, the transfer track 222 includes a lifting frame 2221 and a transfer frame 2222. The lifting frame 2221 is movably arranged on the support frame 21, and a material blocking plate 2223 is upwardly arranged at the rear end of the lifting frame 2221; the front end of the transfer frame 2222 is rotatably arranged on the lifting frame 2221, and the rotation axis 2226 of the transfer frame 2222 is arranged along the left-right direction; when the transfer frame 2222 follows the lifting frame 2221 to be lifted and lowered to be aligned with the feeding track 221, the transfer frame 2222 rotates counterclockwise, so that the transfer frame 2222 moves backward The lower part is tilted so that the item box 3 on the feeding track 221 can automatically slide backward to the transfer rack 2222, until the item box 3 is completely moved to the transfer rack 2222, and the baffle plate 2223 is used to limit the item box 3 from continuing to slide backward; when the transfer rack 2222 follows the lifting rack 2221 to be raised and lowered to be aligned with the removal track 223, the transfer rack 2222 rotates clockwise, so that the transfer rack 2222 is tilted forward and downward, so that the item box 3 on the transfer rack 2222 can automatically slide forward to the removal track 223. Since the front end of the transfer rack 2222 is rotatably arranged on the lifting rack 2221, and the rotation axis 2226 of the transfer rack 2222 is arranged in the left-right direction, when the transfer rack 2222 follows the lifting rack 2221 to be raised and lowered to align with the feeding track 221, the transfer rack 2222 is controlled to rotate counterclockwise, so that the transfer rack 2222 is tilted downward and backward, so that the object box 3 on the feeding track 221 automatically slides backward to the transfer rack 2222 under the action of gravity; in addition, under the blocking action of the baffle plate 2223, the object box 3 that slides from the feeding track 221 to the transfer rack 2222 3 will not slide down from the rear end of the transfer rack 2222, and in the process of the lifting rack 2221 being lifted and lowered, the transfer rack 2222 and the article box 3 on the transfer rack 2222 are both in a state of being tilted backward and downward, so the article box 3 on the transfer rack 2222 will not slide down from the front end of the transfer rack 2222; when the transfer rack 2222 moves with the lifting rack 2221 to be aligned with the taking-out track 223, the transfer rack 2222 is controlled to rotate clockwise instantaneously, so that the transfer rack 2222 is tilted forward and downward, and then the article box 3 on the transfer rack 2222 automatically slides forward to the taking-out track 223 under the action of gravity. It should be noted that the present application does not limit the rotatable installation method between the front end of the transfer rack 2222 and the lifting rack 2221. For example, a rotating shaft 2226 is set on the left and / or right side of the front end of the transfer rack 2222, and an axis hole 2227 is set at a position corresponding to the rotating shaft 2226 on the lifting rack 2221, and the rotating shaft 2226 is rotatably connected to the axis hole 2227; and the rotating shaft 2226 (i.e., the transfer rack 2222) is driven to rotate by being equipped with a driving motor.

[0049] Reference Fig.10 as well as Fig.11In this embodiment, an arc groove 2224 is provided at the rear end of the lifting frame 2221, and the axis of the arc groove 2224 coincides with the rotation axis 2226 of the transfer frame 2222; a limit block 2225 is provided on the left and / or right side of the rear end of the transfer frame 2222, and the limit block 2225 is slidably connected to the arc groove 2224. Through the sliding cooperation between the arc groove 2224 and the limit block 2225, the rotation of the transfer frame 2222 is limited, thereby improving the rotation accuracy of the transfer frame 2222.

[0050] Reference Fig.13 as well as Fig.14 In this embodiment, the feeding track 221 is located directly above the removal track 223; the storage assembly 22 also includes an upper clamping member 226 and a lower support member 227, both of which are arranged on the support frame 21; when the transfer frame 2222 rises to align with the feeding track 221, the upper clamping member 226 is used to force the limit block 2225 to slide to the lower end of the arc groove 2224, so that the transfer frame 2222 is automatically tilted backward and downward; when the transfer frame 2222 descends to align with the removal track 223, the lower support member 227 is used to force the limit block 2225 to slide to the upper end of the arc groove 2224, so that the transfer frame 2222 is automatically tilted forward and downward. Fig.15 As shown, when the transfer frame 2222 moves upward following the lifting frame 2221 until the limit block 2225 contacts the upper pressing member 226, the limit block 2225 (i.e., the rear end of the transfer frame 2222) cannot continue to move upward. At this time, the lifting frame 2221 and the front end of the transfer frame 2222 can continue to move upward until the limit block 2225 slides downward relative to the lifting frame 2221 to the lower end of the arc groove 2224 (as shown in FIG. Fig.16 As shown in the figure), the lifting frame 2221 cannot continue to move upward. At this time, the transfer frame 2222 is just aligned with the rear end of the feeding track 221, and the transfer frame 2222 is tilted downwardly; when the transfer frame 2222 moves downward with the lifting frame 2221 until the transfer frame 2222 contacts the lower support member 227, the rear end of the transfer frame 2222 (i.e., the limit block 2225) cannot continue to move downward. At this time, the lifting frame 2221 and the front end of the transfer frame 2222 can still continue to move downward until the limit block 2225 slides upward relative to the lifting frame 2221 to the upper end of the arc groove 2224 (as shown in the figure). Fig.17As shown in the figure, the lifting frame 2221 cannot continue to move downward. At this time, the transfer frame 2222 is aligned with the rear end of the removal track 223, and the transfer frame 2222 is tilted forward and downward. As can be seen from the above content, the automatic rotation of the front end of the transfer frame 2222 is achieved through the cooperation of the upper clamping member 226 and the lower support member 227, so that there is no need to provide a separate power source; taking the example of realizing the rotation connection with the rotating shaft 2226 through the shaft hole 2227 and driving by the driving motor, the driving motor can be omitted.

[0051] Reference Figure 12 to Figure 14 In this embodiment, the storage component 22 also includes a starting member 228, which includes a fixed pulley 2281, a connecting rope 2282 and a counterweight 2283. The fixed pulley 2281 is rotatably arranged on the support frame 21; one end of the connecting rope 2282 is connected to the lifting frame 2221, and the other end of the connecting rope 2282 passes around at least one fixed pulley 2281 and then is connected to the counterweight 2283; when the item box 3 slides completely onto the transfer frame 2222, the lifting frame 2221 automatically descends and drives the counterweight 2283 to rise, until the item box 3 on the transfer frame 2222 slides completely onto the removal track 223, and the counterweight 2283 automatically descends, thereby forcing the lifting frame 2221 to automatically rise. When there is no article box 3 on the transfer rack 2222, under the gravity of the counterweight block 2283, the counterweight block 2283 pulls the lifting rack 2221 to slide upward automatically through the connecting rope 2282, so that the lifting rack 2221 automatically rises until the limit block 2225 slides to the lower end of the arc groove 2224, and the lifting rack 2221 stops rising. At this time, the transfer rack 2222 is just aligned with the rear end of the delivery track 221, and the transfer rack 2222 is tilted downward and backward, so that an article box 3 at the last end of the delivery track 221 automatically slides When the object box 3 completely slides onto the transfer rack 2222, the weight of the object box 3 is increased, so that the lifting rack 2221 automatically descends, and at the same time drives the counterweight block 2283 to rise, until the limit block 2225 slides to the upper end of the arc groove 2224, and the lifting rack 2221 stops descending. At this time, the transfer rack 2222 is just aligned with the rear end of the removal track 223, and the transfer rack 2222 is tilted forward and downward, so that the object box 3 on the transfer rack 2222 automatically slides onto the removal track 223. In addition, by increasing or decreasing the number of counterweight blocks 2283, or adjusting the weight of a single counterweight block 2283, the automatic transportation of object boxes 3 of different weights can be satisfied.

[0052] Reference Fig.13 as well as Fig.14In this embodiment, the storage assembly 22 further includes a limit frame 229, which is disposed on the support frame 21 and is used to limit the horizontal shaking of the counterweight block 2283. By being disposed on the limit frame 229, the counterweight block 2283 can be limited to prevent the counterweight block 2283 from shaking horizontally during the lifting process; otherwise, once the counterweight block 2283 shakes horizontally, it is easy to interfere with the movement of the object box 3 and the lifting and lowering of the lifting frame 2221.

[0053] Reference Figure 2 , Figure 3 as well as Fig.11 In this embodiment, the transfer rack 2222 and / or the feeding track 221 and / or the removal track 223 are unpowered roller conveyors. The unpowered roller conveyors do not need to provide a separate power source and can reduce the running resistance of the object box 3 on the transfer rack 2222, the feeding track 221 and the removal track 223.
