Abstract

The invention belongs to the technical field of roadway stacking machines, and particularly relates to a rail type roadway stacking machine for a panel furniture flexible production line, which comprises a chassis, a bearing plate, a limiting module and a bottom supporting plate connected to the chassis in a sliding manner, the bearing plate is connected to the bottom supporting plate in a sliding mode. The limiting module is arranged on the chassis and used for limiting goods loaded on the bearing plate. When the bearing plate resets from the limit position to be contracted in the chassis, the fence is kept in an open state and is supported by the limiting part until the bearing plate is completely contracted in the chassis, at the moment, the limiting part loses efficacy, and the fence is turned over again under the action of gravity and kept in a put-down state. And then when the base plate moves on the track along with the base plate, the fences in the put-down state can be used for limiting the materials on the bearing plate and between the two fences, and therefore the situation that the plates stacked too high deviate or even fall off due to the accelerated speed is avoided.

Description

Technical Field

[0001] The invention belongs to the technical field of aisle stackers, in particular to a rail-type aisle stacker used in a flexible production line of panel furniture. Background Art

[0002] A stacking crane is a special crane that uses a fork or a skewer as a picking device to grab, transport and stack unit cargo in warehouses, workshops, etc., or to pick up and place unit cargo from high-rise shelves.

[0003] A Chinese patent with publication number CN114803951A discloses an aisle stacker, which includes a track and a railcar that slides along the track. The railcar is provided with a load-bearing platform on top, on which a first column and a second column are fixedly mounted, and a supporting crossbeam is connected to the tops of the first and second columns. A cargo platform is provided between the first and second columns, and a drive assembly for driving the cargo platform up and down is fixedly mounted on the first column. A telescopic fork for picking up coils is provided on the cargo platform, and a coil fixing assembly for fixing the coils is provided on the fork body of the telescopic fork. A PLC controller is fixedly mounted on the second column, and the railcar, drive assembly, telescopic fork, and coil fixing assembly are all connected to the PLC controller. This application can fix coiled cargo, prevent the cargo from rolling and falling during transportation, and effectively improve the efficiency and safety of coil handling and stacking.

[0004] As in the prior art mentioned above, in the field of panel furniture production lines, there is also a problem that since most of the materials transferred on the panel furniture production line are panels before and after processing, and the panels are stacked, when these materials are transferred by the stacker, considering that the panels may be stacked higher, as the stacker slides, the acceleration may cause the panels to shift or even fall, thereby affecting the processing efficiency of the production line.

[0005] To this end, the present invention provides a rail-type aisle stacker for a flexible production line of panel furniture. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve the technical problem is: a rail-type aisle stacker for a flexible production line of panel furniture according to the present invention comprises:

[0008] A chassis, and a bottom support plate slidably connected to the chassis;

[0009] A supporting plate is slidably connected to the bottom supporting plate;

[0010] A limit module is provided on the chassis and is used to limit the position of the goods loaded onto the support plate;

[0011] The limiting module includes a gantry, an enclosure and a limiting member; the gantry is fixedly connected to the chassis; two enclosures are provided and are symmetrically rotated and connected at the two corners of the gantry; the limiting member is slidably connected to the gantry and is used to limit the enclosure to prevent the enclosure from resetting immediately after flipping.

[0012] Preferably, a blocking block is fixed to the top of the gantry, and a groove is provided at the tail of the enclosure, and the groove is snap-fitted with the blocking block.

[0013] Preferably, the limiting member includes a sliding rod, a blocking block and a spring. The sliding rod is slidably connected to the gantry, and a blocking block is fixed to the top of the sliding rod, and the blocking block is engaged with the groove on the enclosure; the spring is sleeved on the sliding rod, and the two ends of the spring are respectively fixed to the side wall of the gantry and the blocking block.

[0014] Preferably, side fixing frames are symmetrically fixed on both sides of the chassis, and the gantry is fixed on the top of the side fixing frames; a side fixing plate is fixed on the inner side of the chassis, and a plurality of first guide wheels are rotatably connected to the side fixing plate, and the bottom supporting plate is slidably connected to the chassis via the first guide wheels;

[0015] The middle part of the bottom support plate is rotatably connected to a follower gear, the middle part of the chassis is fixed with a first rack, and the first rack is meshed with the follower gear; the bottom of the support plate is fixed with a second rack, and the second rack is meshed with the follower gear; a plurality of second guide wheels are rotatably connected to the side wall of the bottom of the support plate, and the support plate is slidably connected to the bottom support plate via the second guide wheels.

[0016] Preferably, symmetrically arranged reset cards are fixed to the side walls of the support plate, and the reset cards slide in cooperation with the side walls of the slide rod. When the support plate is reset, the reset cards contact the slide rod and squeeze the slide rod inward, separating the card block from the groove and causing the enclosure to fall.

[0017] Preferably, a symmetrically arranged third rack is fixed to the bottom of the bottom support plate, a transmission shaft is rotatably connected to the side wall of the chassis, and a transmission gear is fixed to the end of the transmission shaft, and the transmission gear is meshed with the third rack.

[0018] Preferably, the middle part of the gantry is also rotatably connected to a top pressure module, and the top pressure module and the transmission shaft are driven by a pulley. When a displacement difference occurs between the bottom support plate and the chassis, the third rack drives the transmission gear to rotate, and the transmission gear drives the top pressure module to rotate via the transmission shaft. The top pressure module rotates and expands to limit the cargo on the support plate after reset.

[0019] Preferably, the top pressure module includes a first pipe sleeve, a deformation unit and a second pipe sleeve; the first pipe sleeve and the deformation unit are each provided in two groups and are arranged symmetrically; the opposite ends of the two deformation units are slidingly connected in the second pipe sleeve; the other ends of the deformation units respectively pass through the first pipe sleeve at the corresponding end; when the transmission gear rotates, the first pipe sleeve is driven to rotate via the pulley, so that the deformation unit and the first pipe generate relative rotation until the deformation unit is unfolded, thereby limiting the cargo on the support plate after reset.

[0020] Preferably, the deformation unit includes a ball screw, a slider and a rocker arm; the end of the first sleeve is fixedly connected to a ball nut, and the ball nut is threadedly matched with the ball screw; the end of the slider is fixedly connected to a retraction rod; three rocker arms are provided, one end of the rocker arm is hinged to the slider, and the other end can swing freely around the hinge axis; the retraction rod is rotatably connected to the ball screw, and the slider is slidably connected in the second sleeve.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. The rail-type aisle stacker for a flexible production line of panel furniture described in the present invention can limit the enclosure when the enclosure is flipped to the point where the tail is perpendicular to the chassis. During the process of the support plate being reset from the extreme position to being retracted in the chassis, the enclosure remains in an open state and is supported by the limiter until the support plate is completely retracted in the chassis. At this time, the limiter fails and the enclosure flips again under the action of gravity and remains in a lowered state. Subsequently, when the chassis moves on the track, the enclosure in the lowered state can be used to limit the materials on the support plate and between the two enclosures, thereby preventing the overly stacked plates from shifting or even falling due to acceleration.

[0024] 2. The rail-type tunnel stacker for the flexible production line of panel furniture described in the present invention can drive the ball screw to move horizontally by producing a threaded fit with the ball screw when the first pipe sleeve rotates. Specifically, when the support plate extends outward, the ball screw moves axially inward and contracts, thereby contracting the rocker arm on the contraction rod. Conversely, when the support plate is reset inward, the ball screw moves axially outward, driving the rocker arm to expand. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] like Figures 1 to 7 As shown, the embodiment of the present invention describes a rail-type aisle stacker for a flexible production line of panel furniture, comprising a chassis 10, a supporting plate 20, a limiting module and a bottom supporting plate 30 slidably connected to the chassis 10; the supporting plate 20 is slidably connected to the bottom supporting plate 30; the limiting module is arranged on the chassis 10, and is used to limit the goods loaded onto the supporting plate 20; the limiting module comprises a gantry 50, an enclosure 40 and a limiting member; the gantry 50 is fixed to the chassis 10; two enclosures 40 are provided, and are symmetrically rotated and connected at the two corners of the gantry 50; the limiting member is slidably connected to the gantry 50, and is used to limit the enclosure 40 to prevent the enclosure 40 from resetting immediately after flipping.

[0036] In one embodiment of the present invention, since the materials transferred on the panel furniture production line are mostly panels before and after processing, and the panels are stacked, when the stacker transfers these materials, considering that the panels may be stacked high, the panels may be offset or even fall due to acceleration when the stacker slides, thereby affecting the processing efficiency of the production line. Based on the above, in one embodiment, a gantry 50 is set on the chassis 10 of the stacker, and two enclosures 40 are symmetrically arranged at the two corners of the gantry 50. Both enclosures 40 can be flipped on the gantry 50. When the supporting plate 20 and the bottom support plate 30 have no displacement difference with the chassis 10, that is, when the supporting plate 20 and the bottom support plate 30 are both retracted in the chassis 10, the enclosure 40 is in the lowered state. When the bottom support plate 30 is displaced and drives the supporting plate 20 to be displaced, as shown in FIG. Figure 1 In the state shown, the supporting plate 20 and the bottom supporting plate 30 are both displaced outward, and the enclosure 40 on the side corresponding to the displacement direction is opened. Specifically, in this embodiment, a second rope is also included to pull the enclosure 40 to flip, one end of the second rope is tied to the root of the enclosure 40, and the middle part of the second rope is guided by the roller, and the other end is tied to the outer end of the supporting plate 20. The side wall of the outer end of the supporting plate 20 refers to the side wall farthest from the chassis 10 after the displacement; it is worth noting that the roller is arranged at the bottom of the gantry 50, that is, when the supporting plate 20 is retracted in the chassis 10, the second rope is in a relaxed state, and the enclosure 40 is in a lowered state under the action of gravity. When the supporting plate 20 is displaced outward to the limit position, the second rope is in a taut state, and the enclosure 40 is also turned over by the tension of the second rope, so that the tail of the enclosure 40 is perpendicular to the surface of the chassis 10. In the above description, it should be noted that the second ropes between the enclosure 40 and the supporting plate 20 are respectively tied to the side walls of the two ends of the supporting plate 20, and it should be noted that when the supporting plate 20 is displaced in any direction, the other end of the second rope on the corresponding side is tied to the side wall of the end farthest from the chassis 10 after the supporting plate 20 is displaced, so that Figure 1As shown, when the supporting plate 20 is displaced to the left, the other end of the second rope at the tail of the left enclosure 40 is tied to the leftmost side wall of the supporting plate 20, and when the supporting plate 20 is displaced to the right to the extreme position, the other end of the second rope at the tail of the right enclosure 40 is tied to the rightmost side wall of the supporting plate 20. Based on the above, when the supporting plate 20 is displaced in any direction, the enclosure 40 in this direction will be flipped open under the tension of the second rope, and when the enclosure 40 is flipped to the tail perpendicular to the chassis 10, the limiting member can be used to limit the enclosure 40. After that, the process of the supporting plate 20 being reset from the extreme position to being retracted in the chassis 10 is completed. In the process, the enclosures 40 are kept in the open state and supported by the limit members until the support plate 20 is completely retracted in the chassis 10, at which time the limit members fail and the enclosures 40 flip over again under the action of gravity and remain in the lowered state. Subsequently, when the chassis 10 moves on the track, the enclosures 40 in the lowered state can be used to limit the materials on the support plate 20 and between the two enclosures 40, so as to avoid the deviation or even falling of the plates stacked too high due to acceleration; however, it should be noted that in one embodiment of the present invention, the goods only enter and exit from one side of the chassis 10, that is, only the enclosures 40 on one side will move, and the other side will remain stationary.

[0037] like Figures 1 to 4 As shown, a blocking block 501 is fixed to the top of the gantry 50 , and a groove 401 is provided at the tail of the enclosure 40 , and the groove 401 is engaged with the blocking block 501 .

[0038] As mentioned above, the fence 40 is used to limit the cargo loaded on the support plate 20 when the support plate 20 is reset and retracted in the chassis 10, so as to prevent the cargo from shifting and falling when the chassis 10 moves on the track due to the large cargo load and the acceleration of the chassis 10 when moving on the track, especially when there is a turn in the track. In response to the above, in one embodiment, a fence 40 is provided to limit the cargo loaded on the support plate 20 to prevent the cargo from shifting or even falling during the movement. In addition, a blocking block is provided on the gantry 50 to ensure that the tail of the fence 40 can be limited by the blocking block 501 after the fence 40 is separated from the limiting member, so as to avoid excessive flipping of the fence 40.

[0039] like Figures 1 to 5 As shown, the limiting component includes a sliding rod 51, a block 52 and a spring 521. The sliding rod 51 is slidably connected to the gantry 50, and a block 52 is fixed to the top of the sliding rod 51, and the block 52 is engaged with the groove 401 on the enclosure 40; the spring 521 is sleeved on the sliding rod 51, and the two ends of the spring 521 are respectively fixed to the side wall of the gantry 50 and the block 52.

[0040] In one embodiment, when the supporting plate 20 moves to one side and the second rope is used to drive the enclosure 40 to flip, as shown in FIG. Figure 4 As shown, at this time, the tail of the enclosure 40 changes from being parallel to the chassis 10 to being perpendicular to the surface of the chassis 10. During the process, the tail of the enclosure 40 will squeeze the limiter on the side wall of the gantry 50, causing the limiter to shrink inward. Afterwards, the limiter is reset, and it is just able to form a snap-fitting relationship with the groove 401 at the tail of the enclosure 40, thereby preventing the enclosure 40 from resetting. It is worth noting that the tail of the enclosure 40 maintains a perpendicular relationship with the surface of the chassis 10, which is based on the taut state of the second rope or the contact between the limiter and the groove 401 to form a snap-fitting relationship. After the groove 401 establishes a snap-fitting relationship with the limiter, even if the second rope is no longer in a taut state, that is, when the support plate 20 changes from the output state to the reset and shrinkage in the chassis 10 When the rear end of the enclosure 40 slides relative to the block 52 to the position of the groove 401, the block 52 pops out under the elastic force of the spring 521 and establishes a clamping relationship with the groove 401, thereby realizing the limiting effect on the rear end of the enclosure 40.

[0041] like Figures 1 to 5 As shown, the chassis 10 is symmetrically fixed with side fixing frames 101 on both sides, and the gantry 50 is fixed to the top of the side fixing frames 101; the inner side of the chassis 10 is fixed with a side fixing plate 12, and the side fixing plate 12 is rotatably connected to a plurality of first guide wheels 13, and the bottom support plate 30 is slidably connected to the chassis 10 via the first guide wheels 13;

[0042] The middle part of the bottom support plate 30 is rotatably connected to a follower gear 32, and the middle part of the chassis 10 is fixed with a first rack 11, which is meshed with the follower gear 32; the bottom of the support plate 20 is fixed with a second rack 21, which is meshed with the follower gear 32; a plurality of second guide wheels 22 are rotatably connected to the side wall of the bottom of the support plate 20, and the support plate 20 is slidably connected to the bottom support plate 30 via the second guide wheels 22.

[0043] like Figures 1 to 2As shown, a symmetrically arranged reset card plate 201 is fixed to the side wall of the support plate 20, and the reset card plate 201 slides with the side wall of the slide rod 51. When the support plate 20 is reset, the reset card plate 201 contacts the slide rod 51 and squeezes the slide rod 51 inward, so that the block 52 is separated from the groove 401, causing the enclosure 40 to fall.

[0044] In one embodiment, when the support plate 20 is about to be completely reset, the reset card plate 201 fixed on the side wall of the support plate 20 can slide with the side wall of the slide bar 51. As the support plate 20 moves, the reset card plate 201 squeezes the slide bar 51 and drives the slide bar 51 to move inward and shrink. At this time, the block 52 follows the movement of the slide bar 51 and can no longer limit the groove 401 at the bottom of the enclosure 40. At this time, the enclosure 40 is no longer limited and can be reset to the lowered state.

[0045] like Figures 1 to 5 As shown, the bottom of the bottom support plate 30 is also fixed with a symmetrically arranged third rack 31, and a transmission shaft 33 is rotatably connected to the side wall of the chassis 10, and a transmission gear 34 is fixed to the end of the transmission shaft 33, and the transmission gear 34 is meshed with the third rack 31.

[0046] In one embodiment, the third rack 31 provided at the bottom of the bottom support plate 30 can be used to transmit the power generated by the displacement of the bottom support plate 30 to the transmission shaft 33 through the transmission gear 34, and can also transmit the power of the transmission shaft 33 to the third rack 31 through the transmission gear 34, thereby driving the bottom support plate 30 to move. When the bottom support plate 30 is displaced, the follower gear 32 is engaged with the second rack 21 to drive the support plate 20 to move. In this process, the transmission shaft 33 is connected to an external servo motor, that is, it is used to drive the support plate 20 to move, thereby realizing a top pressure effect on the goods loaded on the support plate 20.

[0047] like Figures 1 to 2 、 Figures 6 and 7 As shown, the middle part of the gantry 50 is also rotatably connected to a top pressure module, and the top pressure module and the transmission shaft 33 are driven by a pulley. When a displacement difference occurs between the bottom support plate 30 and the chassis 10, the third rack 31 drives the transmission gear 34 to rotate, and the transmission gear 34 drives the top pressure module to rotate via the transmission shaft 33. The top pressure module rotates and expands to limit the cargo on the support plate 20 after reset.

[0048] In one embodiment of the present invention, the pulley between the top pressure module and the transmission shaft 33 is not shown in the figure, but as a prior art, it will not be repeated here. In this embodiment, considering that the stacked plates need to be limited by the fence 40 at both ends when moving on the track with the chassis 10, the top needs to be limited, or a part of the pressure is applied in the vertical direction, so that the overall cargo can remain relatively still and will not be offset or fall under the condition of non-direct contact force. Therefore, in one embodiment, a top pressure module is set in the middle of the gantry 50. When the servo motor outputs the transmission shaft 33, the top pressure module can also be rotated by the pulley. When the top pressure module rotates, it can be released and expanded, thereby applying vertical pressure to the cargo on the support plate 20, thereby ensuring that the cargo is relatively stable during the displacement process with the chassis 10.

[0049] like Figures 1 to 2 、 Figures 6 and 7 As shown, the top pressure module includes a first pipe sleeve 61, a deformation unit and a second pipe sleeve 62; the first pipe sleeve 61 and the deformation unit are each provided in two groups and are symmetrically arranged; the opposite ends of the two deformation units are slidably connected in the second pipe sleeve 62; the other ends of the deformation units respectively pass through the first pipe sleeve 61 at the corresponding end; when the transmission gear 34 rotates, the first pipe sleeve 61 is driven to rotate via the pulley, so that the deformation unit and the first pipe generate relative rotation until the deformation unit is unfolded, thereby limiting the cargo on the support plate 20 after reset.

[0050] In one embodiment of the present invention, when the transmission shaft 33 is transmitted to the top pressure module through the pulley, the first pipe sleeve 61 will rotate, thereby causing relative rotation between the first pipe sleeve 61 and the deformation unit. At this time, the deformation unit will deform and expand, thereby being able to limit and squeeze the goods on the support plate 20 after reset. It is worth noting that since the rotation of the first pipe sleeve 61 and the relative rotation between the deformation unit are generated, the deformation unit can be driven to expand. Conversely, when the first pipe sleeve 61 rotates in the opposite direction, the deformation unit can be driven to contract. It is worth noting that in this embodiment, the goods enter through one side of the chassis 10 and are also sent out from one side of the chassis 10. That is to say, in this embodiment, the goods enter and exit from one side of the chassis 10.

[0051] like Figures 1 to 2 、 Figures 6 and 7 As shown, the deformation unit includes a ball screw 60, a slider 64 and a rocker rod 63; the end of the first sleeve 61 is fixedly connected to a ball nut, and the ball nut is threadedly engaged with the ball screw 60; the end of the slider 64 is fixedly connected to a retraction rod 66; three rocker rods 63 are provided, one end of the rocker rod 63 is hinged to the slider 64, and the other end can swing freely around the hinge axis; the retraction rod 66 is rotatably connected to the ball screw 60, and the slider 64 is slidably connected in the second sleeve 62.

[0052] As mentioned above, when the first sleeve 61 is driven and rotated, it forms a threaded fit with the ball screw 60, which can drive the ball screw 60 to move horizontally. Specifically, when the support plate 20 extends outward, the ball screw 60 moves axially inward and contracts, thereby contracting the rocker 63 on the contraction rod 66. Conversely, when the support plate 20 is reset inward, the ball screw 60 moves axially outward, driving the rocker 63 to expand. It is worth noting that a slide 621 is provided on the surface of the second sleeve 62, and the slide 621 A first rope 622 is connected to the end of the rocker arm 63. In the initial state, the first rope 622 is in a relaxed state. When the ball screw 60 is driven and displaced axially outward, the slide 621 is driven by the first rope 622 to slide on the surface of the second sleeve 62 until it slides to the end. At this time, due to the length limitation of the first rope 622 and the exposure of the second sleeve 62 at the hinged part of the rocker arm 63, the rocker arm 63 can be expanded under the pulling action of the first rope 622, thereby limiting the top of the cargo.

[0053] like Figures 1 to 2 、 Figures 6 and 7 As shown, the top pressure module further includes a support rod 65 , one end of which is slidably connected to the surface of the contraction rod 66 , and the other end is slidably connected to the inner bottom surface of the rocker arm 63 . The support rod 65 is used to support the rocker arm 63 .

[0054] Working principle: A gantry 50 is set on the chassis 10 of the stacker, and two enclosures 40 are symmetrically arranged at the two corners of the gantry 50. Both enclosures 40 can be turned over on the gantry 50. When the supporting plate 20 and the bottom supporting plate 30 do not have a displacement difference with the chassis 10, that is, when the supporting plate 20 and the bottom supporting plate 30 are both retracted in the chassis 10, the enclosure 40 is in the lowered state. When the bottom supporting plate 30 moves and drives the supporting plate 20 to move, as shown in FIG. Figure 1In the state shown, the supporting plate 20 and the bottom supporting plate 30 are both displaced outward, and the enclosure 40 on the side corresponding to the displacement direction is opened. Specifically, in this embodiment, a second rope is also included to pull the enclosure 40 to flip, one end of the second rope is tied to the root of the enclosure 40, and the middle part of the second rope is guided by the roller, and the other end is tied to the outer end of the supporting plate 20. The side wall of the outer end of the supporting plate 20 refers to the side wall farthest from the chassis 10 after the displacement; it is worth noting that the roller is arranged at the bottom of the gantry 50, that is, when the supporting plate 20 is retracted in the chassis 10, the second rope is in a relaxed state, and the enclosure 40 is in a lowered state under the action of gravity. When the supporting plate 20 is displaced outward to the limit position, the second rope is in a taut state, and the enclosure 40 is also turned over by the tension of the second rope, so that the tail of the enclosure 40 is perpendicular to the surface of the chassis 10. In the above description, it should be noted that the second ropes between the enclosure 40 and the supporting plate 20 are respectively tied to the side walls of the two ends of the supporting plate 20, and it should be noted that when the supporting plate 20 is displaced in any direction, the other end of the second rope on the corresponding side is tied to the side wall of the end farthest from the chassis 10 after the supporting plate 20 is displaced, so that Figure 1 As shown, when the supporting plate 20 is displaced to the left, the other end of the second rope at the tail of the left enclosure 40 is tied to the leftmost side wall of the supporting plate 20, and when the supporting plate 20 is displaced to the right to the extreme position, the other end of the second rope at the tail of the right enclosure 40 is tied to the rightmost side wall of the supporting plate 20. Based on the above, when the supporting plate 20 is displaced in any direction, the enclosure 40 in this direction will be flipped open under the tension of the second rope, and when the enclosure 40 is flipped to the tail perpendicular to the chassis 10, the limiting member can be used to limit the enclosure 40. After that, the process of the supporting plate 20 being reset from the extreme position to being retracted in the chassis 10 is completed. In the process, the enclosures 40 are kept in the open state and supported by the limit members until the support plate 20 is completely retracted in the chassis 10, at which time the limit members fail and the enclosures 40 flip over again under the action of gravity and remain in the lowered state. Subsequently, when the chassis 10 moves on the track, the enclosures 40 in the lowered state can be used to limit the materials on the support plate 20 and between the two enclosures 40, so as to avoid the deviation or even falling of the plates stacked too high due to acceleration; however, it should be noted that in one embodiment of the present invention, the goods only enter and exit from one side of the chassis 10, that is, only the enclosures 40 on one side will move, and the other side will remain stationary.

[0055] The enclosure 40 is used to limit the cargo loaded on the support plate 20 when the support plate 20 is reset and retracted in the chassis 10, so as to prevent the cargo from shifting and falling when the chassis 10 moves on the track due to the large cargo load and the acceleration of the chassis 10 when moving on the track, especially when there is a turn in the track. In response to the above, in one embodiment, an enclosure 40 is provided to limit the cargo loaded on the support plate 20, so as to prevent the cargo from shifting or even falling during the movement. In addition, a blocking block is provided on the gantry 50, which can ensure that the tail of the enclosure 40 can be limited by the blocking block 501 after the enclosure 40 is separated from the limiting member, so as to avoid excessive flipping of the enclosure 40.

[0056] When the supporting plate 20 moves to one side and the second rope is used to drive the enclosure 40 to turn over, as shown in FIG. Figure 4 As shown, at this time, the tail of the enclosure 40 changes from being parallel to the chassis 10 to being perpendicular to the surface of the chassis 10. During the process, the tail of the enclosure 40 will squeeze the limiter on the side wall of the gantry 50, causing the limiter to shrink inward. Afterwards, the limiter is reset, and it is just able to form a snap-fitting relationship with the groove 401 at the tail of the enclosure 40, thereby preventing the enclosure 40 from resetting. It is worth noting that the tail of the enclosure 40 maintains a perpendicular relationship with the surface of the chassis 10, which is based on the taut state of the second rope or the contact between the limiter and the groove 401 to form a snap-fitting relationship. After the groove 401 establishes a snap-fitting relationship with the limiter, even if the second rope is no longer in a taut state, that is, when the support plate 20 changes from the output state to the reset and shrinkage in the chassis 10 When the rear end of the enclosure 40 slides relative to the block 52 to the position of the groove 401, the block 52 pops out under the elastic force of the spring 521 and establishes a clamping relationship with the groove 401, thereby realizing the limiting effect on the rear end of the enclosure 40.
