Description

Technical Field

[0001] The invention relates to the technical field of material storage, and in particular to a heavy-load warehouse assembly line for plate storage. Background Art

[0002] Heavy-duty bins are storage devices for heavy goods or materials and are widely used in logistics and engineering fields.

[0003] In order to store a large number of plates, the prior art often adopts the method of increasing the number of storage layers, storage width and storage length of the warehouse. However, in actual implementation, the warehouse is mostly set to a structure with two closed sides and two open ends, and the conveying structure for delivering the plates into the warehouse is mostly arranged at the end of the warehouse. If the storage length of the warehouse increases, the difficulty of arranging the conveying structure at the end of the warehouse increases, and the time waiting for the conveying structure to transport the plates to the inside of the warehouse is also prolonged. The existing solution is that the device for storing plates is mostly as described in the text of the Chinese patent publication number CN109422077A entitled A Plate Cache Warehouse, which sets the warehouse structure as a first metal rod in the form of a multi-layer comb structure, so that the formed storage platform is a cantilever structure with one side open, and uses the bracket on the cantilever side with distributed openings to perform X, Y, and Z three-axis motions to achieve loading and unloading operations of the plates.

[0004] The cantilever structure with one side opening in the cited patent allows the storage bin to arrange the plate conveying structure on the cantilever side of the opening. Although it effectively reduces the difficulty of arranging the conveying structure, in actual implementation, the single-sided cantilever structure often requires a longer force arm structure when used to store plates. This obviously has the problem of insufficient support force, especially for the storage of large-mass plates, which poses certain storage safety risks. In addition, the conveying structure that transports the plates to the bin still needs to perform multi-axis motion, and the waiting time between adjacent plate loading operations is still long, so it needs to be solved urgently. Summary of the invention

[0005] In order to avoid and overcome the technical problems existing in the prior art, the present invention provides a heavy-load warehouse assembly line for plate storage, which ensures that the warehouse can store large-mass plates and reduces the difficulty of arranging the conveying structure, while also conveniently realizing efficient loading and unloading operations of the plates in the warehouse.

[0009] It also includes an export material taking machine arranged at the plate export, on the export bracket of the export material taking machine there is a export lifting frame which is driven by the export hoisting mechanism to do vertical lifting action.

[0016] As a further solution of the present invention: the export lifting frame is provided with a push-pull locking mechanism, which includes a horizontally slidable locking member, and the locking members are arranged in at least two groups distributed on the separated sides of the export lifting frame. A number of support plates are arranged on the export bracket at sides of the locking members and are vertically spaced apart. During the lifting process of the export lifting frame, the locking members can slide horizontally to the supporting surfaces on the corresponding support plates to support the export lifting frame.

[0017] As a further solution of the present invention: a vertically arranged fine-adjusting screw is threadedly connected to the support plate, the head of the fine-adjusting screw protrudes from the upper plate surface of the support plate, and the upper surface of the head of the fine-adjusting screw constitutes the supporting surface.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Use the grabbing frame of the imported stacker to grab the plate and grab it on the feeding platform. At this time, the imported lifting frame will rise again to lift the plate off the ferry trolley. The ferry trolley in the ferry mechanism can transfer the plate again, effectively ensuring the storage efficiency of the production line.

[0021] At the same time, a storage platform composed of storage rollers is arranged in the warehouse, and the two ends of the storage platform constitute the plate inlet and outlet. The storage platform with a long lever arm cantilever structure relative to the side wall opening ensures the safety of the warehouse for the large-mass plates. In addition, the grab frame is integrated with a feeding platform composed of imported support guide wheels. By utilizing the low resistance characteristics of the storage platform and the feeding platform, whether it is feeding through the self-rotation of the storage rollers and the imported support guide wheels, or by setting up a conveying structure on the imported stacker, the conveying structure does not need to enter the deep inside of the warehouse. The imported stacker only needs to feed the plates to the plate inlet of the storage platform. By utilizing the rotation of the storage rollers themselves or the transmission structure arranged on the storage platform or the thrust of the plates entering the storage platform later, the plates at the inlet of the storage platform can be made to enter the deep inside of the warehouse, thereby ensuring that the warehouse can store large-mass plates and reducing the difficulty of arranging the conveying structure, and conveniently realizing the efficient loading and unloading operations of the plates in the warehouse.

[0022] 2. The storage power assembly is arranged at the intervals between the storage rollers of the warehouse body, and the storage power rollers in the storage power assembly are used to elastically squeeze the plates on the storage platform, so that a sufficiently large friction force is formed between the storage power rollers and the plates, and when there is wear on the outer surface of the storage power rollers, the storage power rollers are ensured to be stably in contact with the bottom of the plates. Compared with the transmission structure of the self-rotating storage rollers, it is effectively prevented that the storage rollers are difficult to ensure that the top of the outer edge of the storage rollers is accurately located on the same horizontal line due to problems with installation accuracy and processing accuracy, resulting in uncontrollable contact between the storage rollers and the plates during movement, which in turn leads to uncontrollable transmission power to the plates.

[0023] 3. In order to prevent the plates from slipping directly from the plate outlet during the storage process in the conveying channel, a baffle is arranged at the outlet of the storage channel. A linkage rod is hinged between the baffles of adjacent storage platforms, and the hinge axis of the linkage rod is parallel to the rotation axis of the baffle. On the basis of synchronous rotation between multiple baffles, multiple baffles also form a mutually auxiliary whole, thereby ensuring that the baffle can achieve stable blocking of large-mass plates.

[0024] 4. The imported drive wheel in the imported stacker also adopts the driving method of elastically squeezing the bottom of the plate, so that a sufficiently large friction force is formed between the imported drive wheel and the plate, and when there is wear on the outer surface of the imported drive wheel, it ensures the stable contact between the imported drive wheel and the bottom of the plate. This structural arrangement not only drives the plate stably, but also has the advantages of large transmission stroke and small space occupation.

[0025] 5. In the export reclaimer, a push-pull locking mechanism is provided on the export lifting frame. During the lifting process of the export lifting frame, when the export lifting frame is lifted to the corresponding storage platform, the locking part can slide horizontally to the supporting surface on the corresponding support plate to support the export lifting frame, ensuring that the export lifting frame is in a stable and non-shaking state during the plate discharging process.

[0026] 6. The outlet reclaimer is also provided with an outlet discharging platform composed of an outlet supporting guide wheel. Not only is the discharging damping small, but the plate also adopts the driving mode of elastically squeezing the bottom of the plate by the outlet driving wheel on the discharging platform, so that a sufficiently large friction force is formed between the outlet driving wheel and the plate, and when there is wear on the outer surface of the outlet driving wheel, it ensures the stable contact between the outlet driving wheel and the bottom of the plate.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] For ease of understanding, the specific structure and working mode of the present invention are further described below in conjunction with the accompanying drawings:

[0045] The specific structure of the present invention refers to Figure 1-15 As shown, its main structure includes a bin body 30 of a heavy-duty bin, an inlet stacker 10 for feeding the plate material to the inlet of the bin body 30, and an outlet reclaimer 40 for discharging the plate material from the bin body 30. The bin body 30, the inlet stacker 10, and the outlet reclaimer 40 are respectively described in detail below.

[0046] 1. Warehouse 30

[0047] like Fig.12 As shown, the warehouse body 30 includes a support frame 32, the inner side of the support frame 32 forms a storage channel for storing plates, and the two ends of the storage channel respectively constitute the outlet and the inlet of the plates. The inner side of the storage channel is rotatably matched with a storage roller 33 whose rotation axis is horizontal and perpendicular to the length direction of the storage channel. The storage rollers 33 are arranged to be spaced along the length direction of the storage channel. The outer edge top sides of all the storage rollers 33 together constitute a storage platform for the plates, and the plates are transported with low resistance by rolling on the storage platform.

[0048] Specifically, Fig.14 and 15 As shown, a storage power assembly 35 is arranged at the interval of the storage roller 33, and the storage power assembly 35 includes a storage power roller 354 driven by a storage power motor 351 and whose rotation axis is parallel to the rotation axis of the storage roller 33; the storage power assembly 35 is elastically and movably connected to the inner side of the storage channel, so that the outer edge top side of the storage power roller 354 can produce an elastic squeezing action of elastically squeezing the plate on the storage platform. In actual implementation, the outer surface of the storage power roller 354 can be made of high damping materials such as rubber or silicone, and the storage power roller 354 is used to elastically squeeze the plate on the storage platform, so that a sufficiently large friction force is formed between the storage power roller 354 and the plate, and when there is wear on the outer surface of the storage power roller 354, the storage power roller 354 is ensured to be stably abutted against the bottom of the plate. At this time, the storage power roller 354 is driven to rotate by the storage power motor 351, so that the plate can be driven to move on the conveying platform.

[0049] Of course, the storage roller 33 can also be directly connected to the motor or chain connected to the motor to form a self-rotating transmission structure, and the storage roller 33 itself rotates to drive the plate to move on the storage platform. However, due to the problems of installation accuracy and processing accuracy, it is difficult to ensure that the top of the outer edge of the storage roller 33 is accurately located on the same horizontal line in the self-rotating driving mode of the storage roller 33, resulting in uncontrollable contact between the storage roller 33 and the plate during the movement, which further leads to the problem of uncontrollable transmission power of the plate.

[0050] Further, such as Fig.15As shown, the storage power assembly 35 also includes a turntable 352 with one end hingedly engaged on the support frame 32, and the hinge axis of the turntable 352 is parallel to the rotation axis of the storage roller 33. The storage power roller 354 and the storage power motor 351 are both installed on the turntable 352. In the idle state of non-storage, the turntable 352 is driven by the elastic member and the outer edge top side of the storage power roller 354 protrudes above the storage platform. At this time, the extension direction of the cantilever end of the turntable 352 is distributed in the feeding direction of the plate, so that when the plate moves along the feeding direction and squeezes the storage power roller 354, it can squeeze the turntable 352 downward with low resistance; compared with driving the turntable 352 to do lifting and lowering movement through an elastic telescopic rod, it is not easy to have a transmission dead point.

[0051] Furthermore, the elastic driving source for the rotation of the turntable 352 may come from installing a torsion spring at the rotating shaft of the turntable 352. Fig.15 As shown, a support seat 321 fixed to the support frame 32 is fixedly connected directly below the turntable 352, and a support screw 355 penetrating the support seat 321 is swingably connected to the lower part of the turntable 352, and the swing axis of the support screw 355 is parallel to the rotation axis of the storage roller 33. A long hole for the support screw 355 to penetrate is opened on the support seat 321, and the length direction of the hole type of the long hole is parallel to the length direction of the storage channel. The arrangement of the long holes is that when the support screw 355 rotates with the turntable 352, the support seat 321 has a hole for avoiding the support screw 355. There is space for the rod 355 to move; the rod bodies of the support screw 355 located above and below the support seat 321 are respectively provided with assist springs 353 and screwed with positioning nuts 357. The assist springs 353 apply elastic force to the rotation of the turntable 352, and the positioning nuts 357 are arranged to locate the extreme position of the upward sliding of the support screw 355, thereby ultimately locating the idle position of the storage power roller 354 and the initial elastic force of the assist spring 353 in the idle state, to ensure that the plate can stably press the storage power roller 354 downward.

[0052] In addition, if Fig.15 As shown, the support screw 355 is threaded with an elastic force adjustment nut 356 on the rod body located above the assist spring 353. Through the setting of the elastic force adjustment nut 356, when the initial position of the storage power roller 354 in the idle state remains unchanged, the initial elastic force of the assist spring 353 in the idle state and the working elastic force of the assist spring 353 in the working state can be adjusted to ensure that under the elastic force of the assist spring 353, the storage power roller 354 has sufficient friction with the bottom of the plate and will not push the plate to flip upward.

[0053] On the basis of the above, each layer of storage rollers 33 can be set as long strip storage rollers 33, and the two ends of the storage rollers 33 are respectively rotatably matched with the two sides of the storage channel. Figure 12-14 As shown, each layer of storage rollers 33 is arranged in two rows symmetrically distributed on both sides of the storage channel. Although this arrangement structure is also a cantilever structure, the force arm of each storage roller 33 is small when subjected to force, which not only saves costs but also ensures that the rotating shaft of the storage roller 33 is not easily damaged.

[0054] Furthermore, in actual implementation, the storage power assembly 35 can be arranged at the intervals between each storage roller 33, or can be randomly interspersed according to actual needs. Fig.12 As shown, the storage power components 35 are arranged at the intervals between the two columns of storage rollers 33. In the horizontal perspective perpendicular to the storage channel, the storage power components 35 are alternately arranged at the intervals between the two columns of storage rollers 33. Thus, in the horizontal perspective perpendicular to the storage channel, the intervals between adjacent storage power components 35 are ensured and the number of arranged storage power components 35 is reduced. This ensures that the plate materials can obtain stable power transmission during the movement of the storage platform, while reducing the cost of the device.

[0055] The plates stored in the warehouse 30 have certain requirements on the storage environment, such as Fig.11 As shown, the outer wall of the support frame 32 is installed with an insulation board 31, and rolling shutter doors are installed at both ends of the storage channel, ensuring that the warehouse body 30 has relatively good insulation performance and dustproof and waterproof performance.

[0056] In actual implementation, in order to prevent the plates from directly slipping out of the plate outlet during the storage process of the conveying channel, a limiting component 34 is arranged at the outlet of the storage channel. Fig.13 As shown, the storage channel is separated by at least two layers of storage rollers 33 to form at least two material channels, and the limiting assembly 34 includes baffles 341 arranged at the outlets of at least two parallel material channels. The baffles 341 are rotatably matched at the material channels, and the rotation axis of the baffles 341 is parallel to the movement direction of the plate at the outlet of the material channels, so that the baffles 341 are in an open state to avoid the outlet of the material channels and a blocked state to intersect with the outlet of the storage channel during the rotation process. In addition, a linkage rotating rod 342 is hinged between adjacent baffles 341, and the hinge axis of the linkage rotating rod 342 is parallel to the rotation axis of the baffles 341. On the basis of making multiple baffles 341 rotate synchronously, multiple baffles 341 also form a mutually auxiliary whole, thereby ensuring that the baffles 341 can achieve stable blocking of large-mass plates.

[0057] Further, such as Fig.13As shown, one end of the electric telescopic rod 343 is hinged at the outlet of the material channel, and the other end of the electric telescopic rod 343 is hinged to any baffle 341. The two hinge axes of the electric telescopic rod 343 are parallel to the rotation axis of the baffle 341, so that when the electric telescopic rod 343 performs a telescopic action, the baffle 341 is driven to perform a rotation process, thereby realizing the automatic switching between the open state and the blocking state of multiple baffles 341.

[0058] 2. Imported stacker 10

[0059] like Figure 1-5 As shown, the import stacker 10 includes an import bracket 11, on which an import lifting frame 13 driven by an import hoisting mechanism 12 to perform a vertical lifting action is slidably mounted, and the lower part of the import lifting frame 13 is located on both sides of the plate feeding direction and is hinged with a grabbing frame 14 through an import swing seat 141, and the hinge axis of the import swing seat 141 is arranged along the plate feeding direction, and the grabbing frame 14 is driven by a grabbing power mechanism 15 to form a grabbing state close to each other and a releasing state away from each other. The lower part of the import lifting frame 13 is rotatably matched with an import supporting guide wheel 142, and in the grabbing state, the rotation axis of the import supporting guide wheel 142 is horizontal and perpendicular to the plate feeding direction, and the import supporting guide wheels 142 on each side of the import lifting frame 13 are arranged to be at least two horizontally spaced and arranged along the plate feeding direction, and the outer edge top sides of all the import supporting guide wheels 142 in the grabbing state constitute a feeding platform for plate feeding.

[0060] The grabbing power mechanism 15 is initially in a released state. When working, the material is first transported to the bottom of the feed platform through the ferry trolley in the ferry mechanism 20. At this time, the imported hoisting mechanism 12 drives the imported lifting frame 13 to move downward as a whole. At the same time, the grabbing frame 14 on the imported lifting frame 13 is driven by the grabbing power mechanism 15 to approach each other to form a grabbing state, thereby grabbing the plate on the feed platform. At this time, the imported lifting frame 13 makes an upward movement again, lifts the plate off the ferry trolley, and the ferry trolley in the ferry mechanism 20 can transfer the plate again, effectively ensuring the efficiency of production line storage. When the imported lifting frame 13 lifts the plate to the storage platform of the corresponding layer height in the warehouse body 30, the plate can be pushed into the warehouse body 30 by driving the imported support guide wheel 142 to rotate by itself through a motor or relying on other pushing structures installed on the imported lifting frame 13 or manual pushing.

[0061] On the basis of the above, if Figure 5As shown, in the present application, a roller driving structure is used to drive the plate to move from the feeding platform to the storage platform. Specifically, an import drive wheel 145 driven to rotate by an import drive motor 144 is installed on the grabbing frame 14, and the rotation axis of the import drive wheel 145 is parallel to the rotation axis of the import support guide wheel 142; the import drive motor 144 and the import drive wheel 145 are both installed on the import support platform 143, and the import support platform 143 is elastically and movably connected to the grabbing frame 14, so that the outer edge top side of the import drive wheel 145 can produce an elastic squeezing action of elastically squeezing the plate on the feeding platform. Similar to the storage power assembly 35 in the warehouse body 30, the driving mode of the import drive wheel 145 elastically squeezing the bottom of the plate forms a sufficiently large friction force between the import drive wheel 145 and the plate, and also ensures that the import drive wheel 145 is stably abutted against the bottom of the plate when the outer surface of the import drive wheel 145 is worn. At this time, the plate can be driven to move on the feeding platform by rotating the import drive wheel 145.

[0062] Further, such as Figure 5 As shown, one end of the inlet support platform 143 is hingedly matched on the grab frame 14, and the hinge axis of the inlet support platform 143 is parallel to the rotation axis of the inlet drive wheel 145. In the non-working state, the inlet support platform 143 is driven by the elastic member and the outer edge top side of the inlet drive wheel 145 protrudes above the feeding platform. At this time, the extension direction of the cantilever end of the inlet support platform 143 is distributed in the feeding direction of the plate. Similar to the storage power assembly 35 in the warehouse body 30, this allows the plate to move along the feeding direction and squeeze the inlet drive wheel 145, and can squeeze the inlet support platform 143 with low resistance to rotate downward; compared with driving the inlet support platform 143 to do lifting and lowering movement through an elastic telescopic rod, it is not easy to have a transmission dead point.

[0063] Furthermore, Figure 5 As shown, an inlet cushion block 148 fixed to the grab frame 14 is fixedly connected directly above the inlet support platform 143, and an inlet guide screw 146 penetrating the inlet cushion block 148 is swingably connected to the upper part of the inlet support platform 143, and the swing axis of the inlet guide screw 146 is parallel to the rotation axis of the inlet drive wheel 145, and a long hole for the inlet guide screw 146 to penetrate is opened on the inlet cushion block 148, and the hole length direction of the long hole is parallel to the sheet material feeding direction, and the rod body of the inlet guide screw 146 located above and below the inlet cushion block 148 is respectively sleeved with an inlet spring 147 and a screwed inlet lower nut 1462. The rod body of the inlet guide screw 146 located above the inlet spring 147 is also screwed with an inlet upper nut 1461. Similar to the storage power assembly 35 in the bin body 30, the position of the imported drive wheel 145 can be positioned and the initial elastic force of the imported spring 147 can be adjusted in the non-working state. At the same time, the elastic force adjustment of the imported spring 147 in the working state is also achieved.

[0064] On the basis of the above, if Figure 3 As shown, the grabbing power mechanism 15 includes a grabbing motor 151 installed in the middle of the inlet lifting frame 13, the output shaft of the grabbing motor 151 is arranged horizontally along the plate feeding direction, the inlet swing seat 141 is located on the inner side wall of the grabbing frame 14, and the output shaft of the grabbing motor 151 is respectively connected to the top of the grabbing frames 14 on both sides through two sets of crank connecting rods 152. When in use, the output shaft of the grabbing motor 151 rotates, driving the two sets of crank connecting rods 152 to drive the grabbing frames 14 on both sides to rotate synchronously, so as to form a grabbing state and a release state respectively, effectively ensuring the synchronization of the rotation of the grabbing frames 14 on both sides.

[0065] Further, such as Figure 3 As shown, at least two grabbing racks 14 on both sides are arranged at intervals along the sheet feeding direction. The service life of the grabbing racks 14 is effectively improved by sharing the weight of the sheet through multiple grabbing racks 14.

[0066] On the basis of the above, since the grabbing frame 14 swings, if the outlet of the feeding platform is flush with the end of the inlet bracket 11 near the silo 30, a gap must be reserved at the column of the inlet bracket 11 for the grabbing frame 14 to swing, which increases the installation area of ​​the device. Therefore, there will be a certain distance between the outlet of the feeding platform and the silo 30. Figure 4 As shown, in order to prevent the plate from tipping over when it is transported to the gap between the outlet of the feeding platform and the warehouse body 30, a guide assembly is arranged at the outlet of the feeding platform, and the guide assembly includes a connecting frame 163 connected to the inlet lifting frame 13, and an auxiliary wheel 162 for auxiliary support of the lower part of the plate and a correction wheel 161 for positioning the positions of both sides of the plate are installed on the connecting frame 163. The auxiliary wheel 162 is used to assist in supporting the lower part of the plate to prevent the plate from tipping over. At the same time, the setting of the correction wheel 161 can also position both sides of the plate to ensure that the plate is accurately transported to the inside of the warehouse body 30.

[0067] 3. Export reclaimer 40

[0068] like Figure 1 and Figure 6-10 As shown, the export material taking machine 40 includes an export bracket 41, on which there is a sliding export lifting frame 43 driven by an export hoisting mechanism 42 to perform a vertical lifting action. The export lifting frame 43 is used to perform a lifting movement to receive the plates at the export of each storage platform in the warehouse body 30.

[0069] Further, such as Figure 7As shown, the outlet lifting frame 43 is provided with a push-pull locking mechanism 45, which includes a horizontally slidable locking member, which is provided in at least two groups distributed on the separated sides of the outlet lifting frame 43. A plurality of support plates 411 are arranged on the outlet bracket 41 beside the locking member and are distributed vertically at intervals. In specific implementation, the number and position of each support plate 411 correspond to the number and position of the storage platform. During the lifting process of the outlet lifting frame 43, when the outlet lifting frame 43 is lifted to the corresponding storage platform, the locking member can slide horizontally to the supporting surface on the corresponding support plate 411 to support the outlet lifting frame 43, ensuring that the outlet lifting frame 43 is in a stable and non-shaking state during the sheet material discharge process.

[0070] In actual implementation, the push-pull locking mechanism 45 can also be used on the import stacker 10. Its installation method on the import stacker 10 is similar to that on the export material collector 40. The import lifting frame 13 used in the import stacker 10 does not shake during the plate feeding process.

[0071] Further, such as Fig. 9 As shown, the locking member is a locking circular shaft 453, and a circular shaft sleeve 452 is fixed on the export lifting frame 43 and is sleeved on the outer circumference of the locking circular shaft 453. The lower part of the outer end of the locking circular shaft 453 adjacent to the support plate 411 has a horizontal pressing surface. The export lifting frame 43 is equipped with a slide rail 455 arranged parallel to the axial direction of the locking circular shaft 453, and a slide plate 454 connected to the inner end of the locking circular shaft 453 slides on the slide rail 455, and a push-pull electric cylinder 451 driving the slide plate 454 to slide back and forth is also installed on the export lifting frame 43. The contact area between the locking member and the supporting surface is increased by using the horizontal pressing surface, ensuring the stability of the bearing of the locking member. In addition, the locking circular shaft 453 and the circular shaft sleeve 452 cooperate with each other, and the locking circular shaft 453 is prevented from rotating by the sliding cooperation between the slide rail 455 and the connecting slide plate 454. Compared with the locking piece directly adopting non-circular structures such as rectangle, in the present application, the circular cross-section of the locking circular shaft 453 is evenly stressed and has good torsional and bending resistance. In addition, the circular cross-section has uniform stress distribution, which can reduce stress concentration and is easy to process through turning, grinding and other processes, thereby ensuring a high degree of fit between the locking circular shaft 453 and the circular shaft sleeve 452.

[0072] like Fig. 9 As shown, the push-pull electric cylinder 451 is floatingly connected to the slide plate 454. The specific floating connection form can adopt a universal joint or a cross connecting rod, etc., which reduces the coaxiality requirement of the push-pull electric cylinder 451 and the locking circular shaft 453, thereby reducing the installation difficulty of the push-pull electric cylinder 451.

[0073] On the basis of the above, in order to prevent the position of the supporting surface of the support plate 411 from having slight processing deviations, such as Figure 7As shown, a vertically arranged fine-adjusting screw 412 is threadedly connected to the support plate 411, and the head of the fine-adjusting screw 412 protrudes from the upper plate surface of the support plate 411. The upper surface of the head of the fine-adjusting screw 412 constitutes a supporting surface. By rotating the fine-adjusting screw 412, the height of the supporting surface can be adjusted.

[0074] When implementing, Figure 6 As shown, the outlet lifting frame 43 is a rectangular structure, and the locking members are arranged in four groups respectively distributed at the four corners of the outlet lifting frame 43, so that the locking members support the outer periphery of the outlet lifting frame 43 more evenly and stably. Of course, in actual implementation, the locking members can also be arranged in other numbers such as 5 or 6 according to actual needs, as long as the outlet lifting frame 43 can be supported during the discharge process.

[0075] On the basis of the above, if Figure 6 and Fig.10 As shown, the outlet lifting frame 43 is rotatably equipped with at least two outlet supporting guide wheels 442 horizontally spaced along the sheet material discharging direction. The rotating axis of the outlet supporting guide wheel 442 is horizontal and perpendicular to the sheet material discharging direction, so as to reduce the friction resistance between the sheet material and the outlet lifting frame 43 during the sheet material discharging process.

[0076] Further, such as Figure 6 and Fig.10 As shown, guide frames 44 are installed on both sides of the lower part of the outlet lifting frame 43, and the outlet support guide wheels 442 are arranged in two rows installed at the lower part of the guide frames 44 on both sides. The lower part of the outlet lifting frame 43, the inner side wall of the guide frame 44 and the outer edge top of all the outlet support guide wheels 442 are enclosed together to form a discharge channel for sheet material discharge. The form of forming the discharge channel directly below the outlet lifting frame 43 can effectively prevent the sheet material from tipping over along the sheet material conveying direction during the discharge process, and at the same time, it can also realize the positioning of both sides during the discharge process of the sheet material, ensuring that the sheet material can be discharged stably.

[0077] like Figure 8 As shown, the inner side wall of the guide frame 44 is hinged to the side wall of the outlet lifting frame 43 through the outlet swing seat 441, the hinge axis of the outlet swing seat 441 is parallel to the horizontal discharge direction of the plate, and a fine adjustment telescopic rod 46 is hinged between the top of the guide frame 44 and the outlet lifting frame 43, and the hinge axes at both ends of the fine adjustment telescopic rod 46 are parallel to the hinge axis of the outlet swing seat 441. By contracting or stretching the fine adjustment telescopic rod 46, the guide frame 44 can be slewed and adjusted around the hinge axis of the outlet swing seat 441 to ensure that the axis of the outlet support guide wheel 442 on the guide frame 44 is horizontal and perpendicular to the discharge direction of the plate, thereby improving the installation accuracy of the outlet support guide wheel 442.

[0078] Furthermore, Fig.10As shown, the guide frame 44 is equipped with an outlet drive wheel 445 driven to rotate by an outlet drive motor 444, and the rotation axis of the outlet drive wheel 445 is parallel to the rotation axis of the outlet support guide wheel 442; the outlet drive motor 444 and the outlet drive wheel 445 are both installed on the outlet support platform 443, and the outlet support platform 443 is elastically and movably connected to the guide frame 44, so that the outer edge top side of the outlet drive wheel 445 can produce an elastic squeezing action of elastically squeezing the plate on the discharge channel. Similar to the storage power assembly 35 in the warehouse body 30, the drive mode of the outlet drive wheel 445 elastically squeezes the bottom of the plate, so that a sufficiently large friction force is formed between the outlet drive wheel 445 and the plate, and when there is wear on the outer surface of the outlet drive wheel 445, the outlet drive wheel 445 is ensured to be stably in contact with the bottom of the plate. At this time, the plate can be driven to move on the discharge platform by rotating the outlet drive wheel 445.

[0079] Further, such as Fig.10 As shown, one end of the outlet support platform 443 is hingedly matched on the guide frame 44, and the hinge axis of the outlet support platform 443 is parallel to the rotation axis of the outlet drive wheel 445. In the non-working state, the outlet support platform 443 is driven by the elastic member and the outer edge top side of the outlet drive wheel 445 protrudes into the discharge channel. At this time, the extension direction of the cantilever end of the outlet support platform 443 is distributed in the sheet feeding direction. Similar to the storage power assembly 35 in the warehouse body 30, this allows the sheet to move along the discharge direction and squeeze the outlet drive wheel 445, and the outlet support platform 443 can be squeezed downward with low resistance; compared with the outlet support platform 443 driven by the elastic telescopic rod to do the lifting movement, it is not easy to have a transmission dead point. In addition, an outlet pad 448 fixed to the guide frame 44 is fixedly connected directly above the outlet support platform 443, and an outlet guide screw 446 penetrating the outlet pad 448 is swingably connected to the upper part of the outlet support platform 443. The swing axis of the outlet guide screw 446 is parallel to the rotation axis of the outlet drive wheel 445. A long hole for the outlet guide screw 446 to pass through is opened on the outlet pad 448, and the length direction of the long hole is parallel to the length direction of the discharge channel. The rod body of the outlet guide screw 446 located above and below the outlet pad 448 is respectively sleeved with an outlet spring 447 and a lower outlet nut 4462 screwed thereon, and the rod body of the outlet guide screw 446 located above the outlet spring 447 is also threadedly screwed with an upper outlet nut 4461. Similar to the storage power assembly 35 in the bin body 30, the position of the outlet drive wheel 445 can be positioned and the initial elastic force of the outlet spring 447 can be adjusted in the non-working state. At the same time, the elastic force adjustment of the outlet spring 447 in the working state is also achieved.
