Description

Technical Field

[0001] This application relates to the technical field of plastic bag storage, and particularly relates to a storage device and a plastic bag transfer device. Background Art

[0002] Currently, when it is necessary to use plastic bags to package products, the stacked plastic bags are usually placed in a storage device, and a suction cup is driven by a moving mechanism to sequentially suck out the plastic bags in the storage device and move them to the required positions.

[0003] In the existing storage device, except for the surrounding box walls, there is no other structure to limit the plastic bags. The plastic bags have a large sliding property. When the suction cup sucks up the topmost plastic bag, other plastic bags will shift within the storage device. In addition, when initially placing the whole stack of plastic bags into the storage device, the positions of the plastic bags are also prone to being disordered, affecting the adsorption effect of the suction cup. Utility Model Content

[0004] This application aims to solve at least one of the technical problems existing in the prior art. For this purpose, this application provides a storage device and a plastic bag transfer device, which solve the problem that plastic bags are prone to being disordered and shifted in the storage device in the prior art.

[0005] The purpose of this application can be achieved through the following technical solutions:

[0006] In a first aspect, this application provides a storage device, including a bottom plate, a baffle, and at least two limiting rods. The baffle is arranged around the bottom plate to enclose a storage tank above the bottom plate. The storage tank is configured to store stacked plastic bags. The limiting rods are perpendicular to the bottom plate and extend into the storage tank. At least two insertion holes are opened in each plastic bag, and the limiting rods freely pass through the corresponding insertion holes.

[0007] In this application, by setting at least two limiting rods extending into the storage tank, the limiting rods pass through the corresponding insertion holes on the plastic bags to limit the plastic bags, preventing the plastic bags from being disordered and shifted in the storage tank.

[0008] Optionally: The storage device further includes a moving member. The moving member is arranged below the bottom plate and is configured to be able to move up and down relative to the bottom plate. The limiting rods are arranged on the moving member.

[0009] By setting a moving member that can move up and down relative to the bottom plate and arranging the limiting rods on the moving member, the limiting rods can move up and down with the moving member to change the length of the limiting rods extending into the storage tank. This facilitates the subsequent gradual descent of the limiting rods in the storage tank as the plastic bags in the storage tank decrease, preventing the limiting rods from protruding too much above the plastic bags, so that the plastic bags can be separated from the limiting rods later.

[0010] Optionally, at least one pressure-bearing rod is provided on the moving member. The upper end of the pressure-bearing rod passes through the bottom plate and extends to one side of the storage tank. A second linear bearing that is slidably engaged with the pressure-bearing rod is provided on the bottom plate.

[0011] Or,

[0012] At least one pressure-bearing plate is provided on the moving member, and the pressure-bearing plate is arranged on one side of the storage tank.

[0013] By providing the pressure-bearing rod or the pressure-bearing plate, it is convenient for the subsequent transfer mechanism to drive the moving member to descend by pressing the pressure-bearing rod or the pressure-bearing plate.

[0014] Optionally, at least two bag pressing plates are provided on the moving member, and the bag pressing plates extend above the bottom plate. The bag pressing plates are configured to press the bag against the bottom plate from at least two sides of the bag.

[0015] By providing at least two bag pressing plates on the moving member, the bag pressing plates can press the bag against the bottom plate from at least two sides of the bag, preventing the bag from warping at the corners, ensuring that the subsequent transfer device can accurately adsorb the opening of the bag, and further ensuring that the opening of the bag is effectively opened in the later stage for reliable bagging of the subsequent materials. When the moving member descends, it can also drive the bag pressing plates to descend simultaneously. That is, when the bags in the storage tank decrease, the bag pressing plates will also descend accordingly, ensuring that the bag pressing plates can always press the bags.

[0016] Optionally, the storage device further includes a lifting mechanism. The moving member is arranged at the driving end of the lifting mechanism, and the lifting mechanism is configured to drive the moving member to lift.

[0017] By providing the lifting mechanism, the lifting mechanism can actively drive the moving member to move up and down.

[0018] Optionally, the storage device further includes a second elastic member and a check mechanism. When the moving member descends under an external force, it is configured to press the second elastic member, and the check mechanism is configured to restrict the moving member from rising due to the rebound of the second elastic member.

[0019] By providing the second elastic member and the check mechanism, the second elastic member elastically deforms as the moving member descends, and the check mechanism restricts the moving member from rising due to the rebound of the second elastic member, avoiding the moving member from moving up and resetting when the external force driving the moving member to descend disappears. When the restriction of the check mechanism on the moving member is released, the second elastic member can promote the moving member to move up and reset through rebound, which is convenient and fast.

[0020] Optionally, at least one first guide rod is fixedly installed on the bottom plate. The lower end of the first guide rod passes through the moving member and extends below the moving member. A first linear bearing that is slidably engaged with the first guide rod is provided on the moving member.

[0021] By setting the first guide rod and the first linear bearing, the moving part is slidably connected to the first guide rod through the first linear bearing, guiding the up and down movement of the moving part and ensuring the stability of the up and down movement of the moving part.

[0022] Optionally: The storage device further includes a connecting plate. There are at least two first guide rods. The connecting plate is configured to connect all the first guide rods. The connecting plate is located below the moving part. The second elastic member is sleeved on the first guide rod, and the upper end of the second elastic member is connected to or abuts against the first linear bearing, and the lower end of the second elastic member is connected to or abuts against the connecting plate.

[0023] By setting at least two first guide rods, the stability of the lifting of the moving part is ensured. And a connecting plate is provided to connect all the first guide rods, and the second elastic member is sleeved on the first guide rod. The upper end of the second elastic member is connected to or abuts against the first linear bearing, and the lower end of the second elastic member is connected to or abuts against the connecting plate, so that the second elastic member is compressed and deformed when the moving part descends.

[0024] Optionally: The check mechanism includes a toothed plate and a check component. The toothed plate is fixedly connected to the bottom plate. The check component is installed on the moving part. A plurality of tooth grooves are arranged at intervals in the vertical direction on the toothed plate. When the moving part descends, the check component is configured to be sequentially engaged with the plurality of tooth grooves on the toothed plate to limit the upward bounce of the moving part.

[0025] A specific design style of the check mechanism is provided, with a simple structure and convenient use.

[0026] Optionally: A first elastic member is sleeved on the pressure-bearing rod. The upper end of the first elastic member is connected to or abuts against the pressure-bearing rod, and the lower end of the first elastic member is connected to or abuts against the second linear bearing.

[0027] By sleeving the first elastic member on the pressure-bearing rod, after all the bags in the storage tank are taken away, the first elastic member can also drive the moving part to move upward and reset by its rebound.

[0028] Optionally: The storage device further includes at least one brush, and the brush is located on the lifting path of the bags in the storage tank.

[0029] By setting the brush, when the topmost bag in the storage tank is sucked up, the brush can brush down the second layer and the following adhered bags, ensuring that only one bag is sucked up each time.

[0030] In a second aspect, the present application provides a bag transfer device. The bag transfer device includes a transfer mechanism and the above storage device. The transfer mechanism includes a lifting drive member, a lifting member, and a suction cup assembly provided on the lifting member. The lifting drive member is configured to drive the lifting member to lift and use the suction cup assembly to sequentially suck out the bags in the storage device.

[0031] The bag transfer device provided in this application can limit the position of the bags in the storage trough through the limiting rod, so that the bags can be neatly stacked in the storage trough, avoiding the bags from being easily mixed up due to the large sliding properties. Furthermore, due to the setting of the limiting rod, when the suction cup assembly sucks up the top bag, the other bags will not be displaced, thus ensuring the suction effect of the subsequent suction cup assembly.

[0032] Optionally: the storage device further comprises a moving part, the moving part is arranged below the base plate, the moving part is configured to be able to move up and down relative to the base plate, the limiting rod is arranged on the moving part, and the lifting part is configured to be able to press the moving part to make it descend when descending.

[0033] By providing a lifting member that can press the moving member to lower it when it descends, the lifting drive member can synchronously drive the moving member to descend while driving the suction cup assembly to descend, avoiding the need for a separate lifting mechanism for driving the moving member to descend.

[0034] Optional: The lifting part includes a mounting part and a pressing plate. The suction cup assembly is installed on the mounting part.

[0051] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0052] In some embodiments, please refer to Figure 1 As shown, the present application provides a storage device 1, which includes a bottom plate 10, a baffle 11, and at least two limiting rods 12. The baffle 11 is arranged around the bottom plate 10 to enclose a storage tank above the bottom plate 10. The storage tank is configured to store stacked material bags 200. The limiting rods 12 are perpendicular to the bottom plate 10, and the limiting rods 12 extend into the storage tank. At least two insertion holes are opened in each material bag 200, and the limiting rods 12 freely pass through the corresponding insertion holes.

[0053] When a plurality of stacked material bags 200 are placed in the storage tank, the limiting rods 12 can pass through the corresponding insertion holes on the material bags 200 to limit the material bags in the storage tank, avoiding displacement and disorder due to the large sliding property between the material bags 200.

[0054] In some embodiments, please refer to Figure 1 As shown, the storage device 1 further includes a moving member 13. The moving member 13 is arranged below the bottom plate 10 and is configured to be able to move up and down relative to the bottom plate 10. The limiting rods 12 are arranged on the moving member 13. The moving member 13 is in the shape of a horizontal plate and is parallel to the bottom plate 10.

[0055] By driving the moving member 13 to move up and down relative to the bottom plate 10, the moving member 13 drives the limiting rods 12 to move up and down relative to the bottom plate 10, thereby changing the length of the limiting rods 12 extending into the storage tank. That is, while the number of material bags 200 in the storage tank gradually decreases, the limiting rods 12 gradually descend in the storage tank, avoiding that the limiting rods 12 protrude too much above the material bags 200 and affecting the separation of the material bags 200 from the limiting rods 12.

[0056] In some embodiments, please refer to Figure 1 As shown, at least one pressure-bearing rod 14 is arranged on the moving member 13. The pressure-bearing rod 14 is arranged along the moving direction of the moving member 13. The upper end of the pressure-bearing rod 14 passes through the bottom plate 10 and extends to one side of the storage tank. A second linear bearing 15 that is slidably matched with the pressure-bearing rod 14 is arranged on the bottom plate 10, so that the bottom plate 10 can move up and down relative to the moving member 13 along the pressure-bearing rod 14.

[0057] By providing the pressure-bearing rod 14, an external force can cause the moving member 13 to descend relative to the bottom plate 10 by pressing the pressure-bearing rod 14, thereby causing the limiting rod 12 to gradually descend in the material storage groove. And when the limiting rod 12 gradually descends in the material storage groove, the first elastic member is gradually compressed.

[0058] In some other embodiments, please refer to Figure 5 As shown, at least one bearing plate 16 can also be provided on the moving member 13, and the bearing plate 16 is arranged on one side of the material storage groove.

[0059] By providing the bearing plate 16, an external force can drive the moving member 13 to descend by pressing on the bearing plate 16, facilitating the transfer mechanism 100 to drive the moving member 13 to descend.

[0060] In some embodiments, please refer to Figure 1 As shown, at least two bag pressing plates 17 are provided on the moving member 13, and the bag pressing plates 17 extend above the bottom plate 10. The bag pressing plates 17 are configured to press the bag 200 against the bottom plate 10 from at least two sides of the bag 200.

[0061] By providing at least two bag pressing plates 17 on the moving member 13, the bag pressing plates 17 can press the bag 200 against the bottom plate 10 from at least two sides of the bag 200, preventing the bag 200 from warping, ensuring that the subsequent transfer device can accurately adsorb the opening of the bag 200, and further ensuring that the opening of the bag 200 is effectively opened in the later stage for reliable bagging of subsequent materials. And it can lift and lower synchronously with the moving member 13. When the number of bags 200 in the material storage groove decreases, the bag pressing plates 17 can follow the moving member 13 to descend, ensuring that the bag pressing plates 17 can always press the bag 200.

[0062] In some other embodiments, the storage device 1 further includes a lifting mechanism (not shown), the moving member 13 is arranged at the driving end of the lifting mechanism, and the lifting mechanism is configured to drive the moving member 13 to lift and lower.

[0063] When it is necessary to lower or raise the moving member 13, the lifting mechanism can be used to actively drive the moving member 13 to lower or raise.

[0064] In some alternative embodiments, the lifting mechanism is selected from a motor and a lead screw nut mechanism, an electric cylinder, a cylinder, etc.

[0065] In some embodiments, please refer to Figure 1 As shown, the storage device 1 further includes a second elastic member (not shown) and a check mechanism 18. The second elastic member is arranged at the lower end of the moving member 13. When the moving member 13 descends under an external force, it is configured to press the second elastic member, and the check mechanism 18 is configured to limit the upward movement of the moving member 13 due to the rebound of the second elastic member. Exemplarily, the second elastic member is selected as a spring.

[0066] When an external force drives the moving member 13 to descend, the moving member 13 can drive the second elastic member to elastically deform. During this process, the check mechanism 18 always restricts the upward movement of the moving member 13 due to the rebound of the second elastic member, avoiding the rebound of the second elastic member driving the moving member 13 to move upward and reset when the external force driving the moving member 13 to descend disappears. When the moving member 13 needs to be reset, the restriction of the check mechanism 18 on the second elastic member can be released, so that the second elastic member rebounds to drive the moving member 13 to move upward and reset, which is convenient and fast.

[0067] In some embodiments, please refer to Figure 2 As shown, the check mechanism 18 includes a toothed plate 182 and a check component 181. The toothed plate 182 is fixedly connected to the bottom plate 10, and the check component 181 is installed on the moving member 13. A plurality of tooth grooves are arranged at intervals in the vertical direction on the toothed plate 182. When the moving member 13 descends, the check component 181 is configured to sequentially engage with a plurality of tooth grooves on the toothed plate 182 to restrict the upward springing of the moving member 13.

[0068] In one implementation, the toothed plate 18 is vertically fixed to the lower plate surface of the bottom plate 10. Since the check component 181 is an existing part, its specific structure will not be described. During the descent of the moving member 13, the check component 181 can descend along the toothed plate 182 and engage with tooth grooves at different heights on the toothed plate 182 to restrict the moving member 13 at different heights. After the material bag 200 in the storage bin is taken out, when the moving member 13 needs to be reset, the check component 181 can be manually toggled to separate the check component 181 from the toothed plate 182, so that the second elastic member springs the moving member 13 upward to reset.

[0069] In some embodiments, please refer to Figure 1 As shown, at least one first guide rod 19 is fixedly installed on the bottom plate 10. The first guide rod 19 is arranged along the moving direction of the moving member 13. The upper end of the first guide rod 19 is fixedly installed on the bottom plate 10, and the lower end of the first guide rod 19 passes through the moving member 13 and extends below the moving member 13. A first linear bearing 20 that slidably cooperates with the first guide rod 19 is arranged on the moving member 13.

[0070] By arranging the first guide rod 19 and the first linear bearing 20, the moving member 13 is slidably connected to the first guide rod 19 through the first linear bearing 20 to guide the up and down movement of the moving member 13 and ensure the stability of the movement of the moving member 13.

[0071] In some embodiments, please refer to Figure 1As shown, the storage device 1 further includes a connecting plate 21. At least two first guide rods 19 are provided, and the connecting plate 21 is configured to connect all the first guide rods 19. The connecting plate 21 is located below the moving member 13. The second elastic member is sleeved on the first guide rod 19, and the upper end of the second elastic member is connected to or abuts against the first linear bearing 20, and the lower end of the second elastic member is connected to or abuts against the connecting plate 21.

[0072] By providing at least two first guide rods 19, the stability of the lifting of the moving member 13 is ensured. And the connecting plate 21 is provided to connect all the first guide rods 19, the second elastic member is sleeved on the first guide rod 19, the upper end of the second elastic member is connected to or abuts against the first linear bearing 20, and the lower end of the second elastic member is connected to or abuts against the connecting plate 21, so that when the moving member 13 descends, the second elastic member is compressed and deformed.

[0073] In some embodiments, a first elastic member (not shown) is sleeved on the pressure-bearing rod 14. The upper end of the first elastic member is connected to or abuts against the pressure-bearing rod 14, and the lower end of the first elastic member is connected to or abuts against the second linear bearing 15. Exemplarily, the first elastic member is a spring.

[0074] Similarly, when the material bag 200 in the storage tank is taken out completely, the external force applied to the moving member 13 is cancelled, and the first elastic member can also rebound to drive the moving member 13 to reset.

[0075] In some embodiments, please refer to Figure 1 As shown, the storage device 1 further includes at least one brush 22, and the brush 22 is located on the lifting path of the material bag 200 in the storage tank.

[0076] In one implementation, four brushes 22 are provided. The four brushes 22 are all installed on the stop block and are respectively arranged around the top of the storage tank. The brush head of each brush 22 extends above the storage tank. When the topmost material bag 200 in the subsequent storage tank is sucked up, the four brushes can respectively brush down the second and subsequent material bags 200 adhered together from the four sides of the material bag 200, ensuring that only one material bag 200 is sucked up each time.

[0077] In some embodiments, the storage device 1 further includes at least one limit bolt 23. The limit bolt 23 is fixedly installed on the bottom plate 10, and at least part of the limit bolt 23 extends below the bottom plate 10. The limit bolt 23 is used to limit the reset of the moving member 13, that is, when the moving member 13 resets, the moving member 13 abuts against the limit bolt 23 to prevent the moving member 13 from colliding with the bottom plate during the ascending process.

[0078] In some embodiments, please refer to Figure 3 and Figure 4As shown in the figure, the present application provides a bag transfer device 1000. The bag transfer device 1000 includes a transfer mechanism 100 and the above-mentioned storage device 1. The transfer mechanism 100 includes a lifting drive member 101, a lifting member 102, and a suction cup assembly 103 provided on the lifting member 102. The lifting drive member 101 is configured to drive the lifting member 102 to lift and sequentially suck out the bags 200 in the storage device 1 by using the suction cup assembly 103.

[0079] In the bag transfer device 1000 provided in the present application, the bags 200 in the storage tank can be limited by the limiting rod 12, so that the bags 200 can be neatly stacked in the storage tank, avoiding the disorder of the bags 200 due to large sliding. And through the setting of the limiting rod 12, when the suction cup assembly 103 sucks up the topmost bag 200, the other bags 200 will not shift, ensuring the adsorption effect of the subsequent suction cup assembly 103.

[0080] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 4 As shown in the figure, the storage device 1 further includes a moving member 13. The moving member 13 is provided below the bottom plate 10, and the moving member 13 is configured to be able to move up and down relative to the bottom plate 10. The limiting rod 12 is provided on the moving member 13, and the lifting member 102 is configured to be able to press the moving member 13 to make it descend when descending.

[0081] By providing the lifting member 102 that can press the moving member 13 to make it descend when descending, the lifting drive member 101 can synchronously drive the moving member 13 to descend while driving the suction cup assembly 103 to descend, avoiding the need to separately provide a lifting mechanism for driving the moving member 13, with a simple structure and reduced cost.

[0082] In some embodiments, please refer to Figure 5 and Figure 6 As shown in the figure, the lifting member 102 includes a mounting member 1021 and a pressing plate 1022. The suction cup assembly 103 is mounted on the mounting member 1021, and the mounting member 1021 is further configured to be able to press the moving member 13 to make it descend when descending. The pressing plate 1022 is elastically mounted below the mounting member 1021, and the pressing plate 1022 is configured to elastically press the bags 200 in the storage tank.

[0083] In one implementation, please refer to Figure 4As shown, the mounting member 1021 is mounted on the driving end of the lifting driving member 101. At least one second guiding rod 104 and a third elastic member (not shown) sleeved on the second guiding rod 104 are provided on the pressing plate 1022. At least one third linear bearing 105 slidably engaged with the second guiding rod 104 is provided on the mounting member 1021. The upper end of the third elastic member is connected to or abuts against the third linear bearing 105, and the lower end of the third elastic member is connected to or abuts against the pressing plate 1022.

[0084] The lifting driving member 101 drives the mounting member 1021, the pressing plate 1022 and the suction cup assembly 103 to synchronously descend, so that the pressing plate 1022 first presses on the material bag 200 in the storage tank, keeping the material bag 200 flat before being adsorbed, which is convenient for subsequent adsorption. After the pressing plate 1022 presses on the material bag 200 in the storage tank, the lifting driving member 101 continues to drive the mounting member 1021 to descend, so that the mounting member 1021 compresses the third elastic member and approaches the pressing plate 1022 along the second guiding rod 104 until the suction cup assembly 103 adsorbs the topmost material bag 200 in the storage tank. After that, the lifting driving member 101 drives the material bag 200 to rise and move away from the storage tank.

[0085] During the process of the lifting driving member 101 driving the mounting member 1021 to descend, the mounting member 1021 presses on the bearing rod 14 or the bearing plate 16 to drive the moving member 13 to synchronously descend with the mounting member 1021.

[0086] In some embodiments, please refer to Figure 4 As shown, the transfer mechanism 100 further includes a lateral movement driving member 106. The lifting driving member 101 is arranged at the driving end of the lateral movement driving member 106, and the lateral movement driving member 106 is configured to drive the transfer mechanism 100 to move laterally.

[0087] By providing the lateral movement driving member 106, the transfer mechanism 100 can move laterally, so as to laterally transfer the sucked material bag 200 and increase the working area of the suction cup assembly 103.

[0088] In one implementation, the lateral movement driving member 106 includes a linear module 1061 and a first mounting frame 1062 arranged at the free end of the linear module 1061.
