Description

Technical Field

[0001] This utility model relates to the field of automatic feeding device technology, and in particular to an automatic pallet feeding device for material carts. Background Technology

[0002] In production activities, raw materials, semi-finished products, and finished products are usually placed in an orderly manner using pallets to facilitate circulation and storage.

[0003] In existing technologies, pallet loading during automated or semi-automated assembly is typically done manually. For example, a person manually places stacked pallets at the loading position, and then a robotic arm or other automated mechanism retrieves materials from the pallets one by one to perform the corresponding production operations. However, existing manual pallet loading methods are limited to situations where the pallets are small in size and the overall load is light.

[0004] When the pallet size is large or too large, such as a pallet with a length and width of 685mm*600mm, and the weight of a single pallet exceeds 2kg, and there are more than ten layers of stacked pallets, it is not possible to manually load the pallets by manual handling. Utility Model Content

[0005] To address the aforementioned issues, this application provides a rationally structured automatic pallet feeding device for material carts, thereby enabling automatic feeding of stacked pallets by the material cart. It is particularly suitable for feeding stacked pallets of medium to large size and under medium to heavy load conditions, effectively replacing manual labor and offering excellent practicality.

[0006] The technical solution adopted in this utility model is as follows: An automatic pallet loading device for a material cart includes a conveyor line with a recessed space at one end, and lifting mechanisms on both sides of the space. It also includes a trolley with a platform carrying stacked pallets. The width of the pallets is greater than the width of the platform, and the sides of the pallets extend outwards relative to the platform. The top of the platform is higher than the conveying height of the conveyor line. When the trolley moves toward the space, the platform is fitted into the space, with the sides of the pallets extending above the conveyor line. The lifting mechanisms are located on both sides of the platform below the pallets.

[0007] As a further improvement to the above technical solution: A limiting mechanism is also provided in one part of the space. The trolley has a slot on its side. When the trolley moves and adapts to the space, the limiting block of the limiting mechanism is installed in the slot to limit the trolley.

[0008] The lifting mechanism has the following structure: it includes a lifting power unit with its output section facing upwards, and a support bar installed on the lifting power output section. The length of the support bar is arranged along the conveying direction of the conveyor line. The lifting power unit drives the support bar to switch between a low position and a high position. The top surface of the support bar in the low position is lower than the conveying height of the conveyor line, and the top surface of the support bar in the high position is higher than the conveying height of the conveyor line. The height of the trolley platform is between the high and low positions of the support bar.

[0009] Stop components are spaced along the conveyor line, and the stopping distance of the stop components is the same as or a multiple of the size of the pallet in the conveyor direction.

[0010] The other end of the conveyor line is equipped with a lifting mechanism, and a lateral support mechanism is provided above the lifting mechanism; the lifting platform of the lifting mechanism is connected to the conveying height of the conveyor line to support the stacked pallets, or the lifting platform moves upward so that the supported pallets are supported by the lateral support mechanism.

[0011] The other end of the conveyor line has a second space for accommodating the lifting mechanism. The width of the lifting platform is smaller than the width of the second space, and the lower position of the lifting platform is lower than the conveying height of the conveyor line.

[0012] It also includes a loading platform, which is located above the lifting mechanism. The loading platform has a through hole for the pallet to pass through. The lateral support mechanism is located at the edge opposite to the through hole. The two sets of lateral support mechanisms are provided with support blocks that move towards or away from each other.

[0013] The conveyor line includes a first conveyor line and a second conveyor line that are connected front and rear. The first conveyor line has a space at one end for the trolley to fit, and the second conveyor line has a lifting mechanism at one end. The conveying lengths of the first conveyor line and the second conveyor line are more than twice the corresponding size of the pallet.

[0014] It also includes two parallel frames, Frame 1 and Frame 2. Conveyor line 1 is located at the lower part of Frame 2, and conveyor line 2 is located at the lower part of Frame 1. The lifting mechanism connected to the end of conveyor line 2 is located inside Frame 1. A loading platform is provided in the middle of Frame 1, and a lateral support mechanism is installed on the loading platform.

[0015] The structure of the lateral support mechanism is as follows: it includes a support installed on the top surface of the loading platform, a lateral support power is installed on the support, the output end of the lateral support power is arranged facing the edge of the pallet and a support seat is installed thereon, and a support block is installed on the support seat. Under the action of the lateral support power, the support block is driven by the support seat to move toward the pallet, and the support block moves horizontally to the bottom of the pallet to support the pallet.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This utility model allows a trolley carrying stacked pallets to travel to a certain space at the end of the conveyor line. A lifting mechanism then lifts the stacked pallets on the trolley upwards, and the trolley exits the conveyor line. The lifting mechanism then moves downwards to place the stacked pallets on the conveyor line, which then carries the pallets towards the loading position. This achieves automatic loading of stacked pallets by the material trolley, and is especially suitable for loading stacked pallets in medium to large-sized and medium to heavy-duty situations. It effectively replaces manual operation and has good practicality. This utility model also has the following advantages: The combination of a trolley and a lifting mechanism with the conveyor line enables automatic feeding of stacked pallets, replacing manual labor, improving work efficiency, saving costs and time, and ensuring full automation of production. By setting up a lifting mechanism at the end of the conveyor line, combined with the upper lateral support mechanism, stacked pallets can be disassembled to realize the one-by-one, sequential loading of individual pallets, which facilitates the effective handling of materials in the pallets. The trolley loads stacked pallets through space one to conveyor line one below frame two. Conveyor line one connects to conveyor line two. Conveyor line two uses a combination of lifting and lateral support mechanisms to unpack the pallets and load them one by one onto the loading platform in the middle of frame one. This achieves a reasonable and ingenious layout for automated loading. Depending on actual needs, other components such as robotic arms can be arranged in the middle and upper parts of frame one and frame two. The overall structure is compact and has a high space utilization rate. Attached Figure Description

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, an automatic pallet loading device for a material cart according to this embodiment includes a conveyor line, with a recessed space 80 at the end of the conveyor line, and lifting mechanisms 9 arranged on both sides of the space 80; it also includes a trolley 1, the platform 101 of the trolley 1 carrying stacked pallets 10, the width of the pallets 10 being greater than the width of the platform 101, and the two sides of the pallets 10 extending outward relative to the platform 101; the top surface height of the platform 101 of the trolley 1 is higher than the conveying height of the conveyor line; when the trolley 1 moves toward the space 80 of the conveyor line, the platform 101 is adapted to be accommodated in the space 80, the two sides of the pallets 10 extending out of the platform 101 are located above the conveyor line, and the lifting mechanisms 9 are located on both sides of the platform 101 below the pallets 10.

[0024] In this embodiment, the trolley 1 carrying the stacked pallets 10 runs to the end space of the conveyor line at position 80. The lifting mechanism 9 lifts the stacked pallets 10 on the trolley 1 upwards, the trolley 1 exits the conveyor line, and the lifting mechanism 9 descends to place the stacked pallets 10 on the conveyor line. The conveyor line carries the pallets 10 to the loading position, thereby realizing the automatic loading of the stacked pallets 10 by the material trolley.

[0025] In actual operation, by making the top surface of the platform 101 of the trolley 1 higher than the conveying height of the conveyor line, when the trolley 1 is adapted to the space 80, the two sides of the stacked pallets 10 extending from the platform 101 are located above the lifting mechanism 9 and the conveying surface of the conveyor line, which effectively ensures that the trolley 1 can carry the pallets 10 smoothly and smoothly to adapt to the space 80; combined with the lifting mechanism 9 lifting the stacked pallets 10 upward from the trolley 1, the trolley 1 can be smoothly pushed out of the space 80, and then the lifting mechanism 9 lowers the pallets 10 to the conveyor line, so that the lifting mechanism 9 can transfer and connect the stacked pallets 10 between the trolley 1 and the conveyor line, effectively ensuring that the pallets 10 are smoothly and automatically fed to the conveyor line.

[0026] In this embodiment, the trolley 1 and the lifting mechanism 9 are combined with the conveyor line to realize the automatic feeding of the stacked pallets 10. While replacing manual labor, it helps to improve work efficiency, save costs and time, and ensure the full automation of production.

[0027] A limiting mechanism 7 is also installed at space 80. The trolley 1 has a slot 102 on its side. When the trolley 1 moves and adapts to space 80, the limiting block of the limiting mechanism 7 is installed in the slot 102 to limit the trolley 1. By limiting and fixing the trolley 1 adapted to space 80 through the limiting mechanism 7, it helps to ensure that the lifting mechanism 9 can stably and reliably receive the pallet 10 from the platform 101 of the trolley 1.

[0028] In this embodiment, the limiting mechanism 7 can use a cylinder as the driving force. The limiting block is installed at the output end of the cylinder, and the output end of the cylinder is arranged along the width direction of the conveyor line towards the space -80. The action of the cylinder drives the limiting block to move, thereby limiting or unlocking the trolley 1.

[0029] The lifting mechanism 9 has the following structure: it includes a lifting power 92 with its output section facing upwards, and a support bar 91 installed on the output section of the lifting power 92. The support bar 91 is arranged along the conveying direction of the conveyor line in the length direction. The lifting power 92 drives the support bar 91 to switch between a low position and a high position. The top surface of the support bar 91 in the low position is lower than the conveying height of the conveyor line, and the top surface of the support bar 91 in the high position is higher than the conveying height of the conveyor line. The height of the trolley 1 platform 101 is between the high and low positions of the support bar 91. This effectively ensures that the lifting mechanism 9 can carry and transfer the pallet 10 between the trolley 1 and the conveyor line.

[0030] In this embodiment, the lifting power 92 can be installed on external supports and other structural components according to actual needs, so that the height of the support bar 91 can match the usage requirements. In actual operation, guide columns 93 and guide sleeves and other conventional guide structures can be set between the support bar 91 and the external support to effectively ensure the reliability and stability of the support bar 91 moving up and down under the drive of the lifting power 92.

[0031] In this embodiment, the lifting power 92 can be a conventional linear drive power such as a cylinder, or other power components can be used, as long as the lifting power 92 can realize the up and down movement of the support 91.

[0032] Stopping components 6 are arranged at intervals along the conveying direction of the conveyor line. The stopping distance of the stopping components 6 is the same as or a multiple of the size of the pallet 10 in the conveying direction.

[0033] In this embodiment, the stop component 6 is used to stop the pallet 10 supported on the conveyor line and moving along the conveyor line in the conveying direction, preventing the pallet 10 from approaching each other and colliding in the conveying direction. Therefore, in one embodiment, the stopping distance of the stop component 6 is consistent with the size of the pallet 10 in the conveying direction. That is, the spacing between two adjacent stop components 6 is adapted to a single stack of pallets 10, so that the stop component 6 can effectively stop the pallet 10 supported on the conveyor line in the conveying direction.

[0034] In this embodiment, the stop assembly 6 can use a cylinder as the driving force. The stop block is installed at the output end of the cylinder, and the output end of the cylinder is arranged inward along the width direction of the conveyor line. The action of the cylinder drives the stop block to move, so that the stop block stops between the adjacent trays 10, or the stop block moves away so that the trays 10 continue to move with the conveyor line.

[0035] A lifting mechanism 2 is provided at the other end of the conveyor line, and a lateral support mechanism 5 is provided above the lifting mechanism 2. The lifting platform 21 of the lifting mechanism 2 is connected to the conveying height of the conveyor line to support the stacked pallets 10, or the lifting platform 21 moves upward so that the supported pallets 10 are supported by the lateral support mechanism 5.

[0036] In this embodiment, by setting up the lifting mechanism 2 at the end of the conveyor line, combined with the upper lateral support mechanism 5, the stacked pallets 10 can be disassembled, so as to realize the sequential loading of individual pallets 10, which facilitates the effective handling of materials in the pallets 10.

[0037] In this embodiment, the lifting mechanism 2 forms the connection between the conveyor line and the lateral support mechanism 5 during the pallet 10 loading process.

[0038] like Figure 4 As shown, a space 21 is provided at the other end of the conveyor line for accommodating the lifting mechanism 2. The width of the lifting platform 21 is smaller than the width of the space 21, which effectively ensures that the lifting platform 21 moves smoothly and easily up and down in the space 21. The lower position of the lifting platform 21 is lower than the conveying height of the conveyor line.

[0039] In actual use, the lifting mechanism 2 and the lifting platform 21 are located at a low position, that is, below the conveying height of the conveyor line. The stacked pallets 10 move toward the lifting mechanism 2 along the conveyor line until the pallets 10 are supported on the conveyor line at the lifting platform 21. Then, the lifting platform 21 moves upward and lifts the stacked pallets 10 supported on the conveyor line upward.

[0040] It also includes a loading platform 4, which is located above the lifting mechanism 2. The loading platform 4 has a through hole for the pallet 10 to pass through. The lateral support mechanism 5 is arranged at the edge opposite to the through hole. The two sets of lateral support mechanisms 5 are provided with support blocks 52 that move towards or away from each other.

[0041] In practical use, the lifting mechanism 2 drives the lifting platform 21 to move upward, so that the pallets 10 stacked on the lifting platform 21 pass upward through the through hole of the feeding platform 4, for example, so that the uppermost pallet 10 is positioned above the support block 52 in height; the lateral support mechanisms 5 on both sides of the through hole of the feeding platform 4 work, driving the support blocks 52 to move towards each other and be positioned below the uppermost pallet 10, so that the uppermost pallet 10 is supported on the lateral support mechanism 5, and the material in the pallet 10 can be taken out by an external robot or other means, and the empty pallet 10 is removed after the material is taken out; then the combined action of the lateral support mechanism 5 and the lifting mechanism 2 is used to operate on the next pallet 10; thus completing and realizing the automatic feeding and taking out of the stacked pallets 10 and the materials in them on the lifting platform 21.

[0042] The conveyor line includes a first conveyor line 8 and a second conveyor line 3 connected front and rear. The first conveyor line 8 has a space 80 at its end for the trolley 1 to fit. The second conveyor line 3 is fitted with a lifting mechanism 2 at its end. The conveying lengths of the first conveyor line 8 and the second conveyor line 3 are more than twice the corresponding size of the pallet 10.

[0043] In this embodiment, the conveyor line is composed of conveyor line 1 8 and conveyor line 2 3 connected together. In other embodiments, the conveyor line can also be a single integral structure or it can be composed of multiple segments. It can be laid out according to actual usage requirements, and the conveyor line can be connected between the trolley 1 and the lifting mechanism 2 to meet actual usage needs.

[0044] In this embodiment, the conveying lengths of conveyor line 18 and conveyor line 23 are set to be more than twice the corresponding size of pallet 10, so that the stacked pallets 10 transferred from the trolley 1 to the conveyor line can form an effective temporary storage on the conveyor line. Combined with the action of the stop component 6, multiple sets of stacked pallets 10 can be stored on the conveyor line at one time.

[0045] It also includes two parallel frames, 11 and 12. Conveyor line 8 is located at the lower part of frame 12, and conveyor line 3 is located at the lower part of frame 11. The lifting mechanism 2 connected to the end of conveyor line 3 is located inside frame 11. A loading platform 4 is provided in the middle of frame 11, and a lateral support mechanism 5 is installed on the loading platform 4.

[0046] In this embodiment, the trolley 1 loads the stacked pallets 10 through space 80 to the conveyor line 8 below the frame 12. The conveyor line 8 is connected to the conveyor line 3. The conveyor line 3 disassembles the pallets 10 through the combination of the lifting mechanism 2 and the lateral support mechanism 5, and loads the pallets 10 one by one to the loading platform 4 in the middle of the frame 11. This realizes a reasonable and ingenious structure layout for automated loading. According to actual needs, other components such as robotic arms can be arranged in the middle and upper parts of the frame 11 and the frame 12. The overall structure is compact and has a high space utilization rate.

[0047] The structure of the lateral support mechanism 5 is as follows: it includes a support 51 installed on the top surface of the loading platform 4, a lateral support power 53 installed on the support 51, a support seat 54 installed at the output end of the lateral support power 53 facing the edge of the pallet 10, and a support block 52 installed on the support seat 54. When the lateral support power 53 is activated, the support block 52 is driven by the support seat 54 to move toward the pallet 10. The support block 52 moves horizontally to below the pallet 10 and supports the pallet 10.

[0048] In actual operation, the top surface of the support block 52 can be set as a stepped surface, and the supported tray 10 can be limited and positioned by the stepped surface.

[0049] In this embodiment, the lateral support power 53 can be a conventional linear drive power such as a cylinder, or other power components can be used, as long as the lateral movement of the support block 52 can be achieved through the lateral support power 53.

[0050] In this embodiment, a back plate can be provided for mounting and supporting the lifting mechanism 2. The lifting mechanism 2 can include a lifting drive power mounted vertically on the back plate, and a lifting platform 21 is installed on the lifting drive power output part. A vertically arranged guide rail can also be provided on the side of the back plate, and the lifting platform 21 is slidably mounted on the guide rail. The guide rail provides guidance and protection for the lifting action of the lifting platform 21. The lifting drive power can be a vertically arranged linear module standard part, or other conventional lifting components can be used, such as a conventional structure in which a motor drives a vertically arranged lead screw to rotate, the lifting platform 21 is slidably mounted on the back plate, and the lead screw is helically mounted on the lifting platform 21, so that the rotation of the lead screw drives the lifting platform 21 to move up and down.

[0051] In this embodiment, vertically arranged support rods 20 can also be set on both sides of the conveyor line at the lifting mechanism 2, so that the support rods 20 can protect the stacked pallets 10 carried by the lifting mechanism 2 when they move upward.

[0052] This invention enables automatic feeding of stacked pallets by a material cart, and is especially suitable for feeding medium and large-sized pallets under medium and heavy load conditions. It effectively replaces manual operation and has good practicality.

[0053] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
