Description

Technical Field

[0001] The utility model relates to the technical field of transport devices, in particular to a tray pushing mechanism for a tray loading line. Background Art

[0002] As a conveying equipment, conveyor lines are widely used in various production and processing fields. Pallet loading lines are a type of conveyor line that uses pallets to carry and move products. Products are placed on pallets and transported by moving pallets.

[0003] In actual production, before the product is officially transported, the pallets are stacked. The stacked pallets need to be disassembled first, and then the disassembled pallets are moved to the workstations one by one through the conveyor, so that the loading line can carry out normal transportation work. The pallets move in a straight line under the action of the conveyor. Due to the space limitations of the site, the loading line workstation is located next to the conveyor. The pallets need to be turned 90° before they can be transferred from the conveyor to the loading line. At present, the conveyor with a 90° arc power roller is commonly used in the factory. The 90° arc roller can effectively make the products in the same plane for vertical reversing transportation. The disadvantage is that the power roller must be made into a cone shape, and the frames on both sides must be made into arc shapes. The production and installation requirements are high, and the cost is high. Utility Model Content

Detailed implementation manners

[0024] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other arbitrarily.

[0025] Please refer to Figures 1 to 3. A pallet loading line includes a synchronous component 11, a synchronous shaft 12, a driving motor 13 and a push plate 14. The synchronous component 11 includes a synchronous belt 111, and a driven wheel 113 and a driving wheel 112 that cooperate with the synchronous belt 111. The synchronous component 11 is provided with at least two groups, and the multiple groups of synchronous components 11 are arranged in intervals and in parallel. The push plate is connected to the synchronous belts 111 in multiple synchronous components 11 at the same time, and the synchronous shaft 12 is connected to multiple driving wheels 112. The driving motor 13 is connected to the synchronous shaft 12. When the driving motor 13 drives the synchronous shaft 12 to rotate, the driving wheels 112 in the multiple synchronous components 11 rotate synchronously, thereby driving the multiple synchronous belts 111 to move synchronously in the same direction, and the synchronous belt 111 drives the push plate 14 to move; the transport direction of the first conveying mechanism 20 for transporting the pallet is perpendicular to the moving direction of the push plate 14. When the first conveying mechanism 20 drives the pallet to move to the pallet mechanism, the push plate 14 contacts the pallet and pushes the pallet to move, thereby realizing the turning movement of the pallet.

[0026] In order to drive the push plate 14 to move, the synchronous assembly 11 is provided with at least two groups, and multiple synchronous belts 111 are arranged in parallel, and the two synchronous assemblies 11 move synchronously and in the same direction. The push plate 14 is connected to the multiple synchronous belts 111 at the same time, so that the synchronous belts 111 drive the push plate 14 to move, and then the push plate 14 is pushed to move. Figure 1 As shown. The moving direction of the push plate 14 is perpendicular to the transport direction of the first conveying mechanism 20, so that the push plate 14 pushes the pallet to move and realizes a 90° turn, that is, the moving direction of the synchronous belt 111 should be perpendicular to the transport direction of the first conveying mechanism 20. In this embodiment, working teeth are arranged on the working surfaces of the driving wheel 112 and the driven wheel 113, and corresponding working teeth are arranged on the inner belt surfaces of the synchronous belt 111 that cooperate with the driving wheel 112 and the driven wheel 113. The synchronous belt 111 and the driving and driven wheels 113 are meshed to transmit the transmission, as shown in FIG. Figure 3 As shown, the mutual slip between the synchronous belt 111 and the master and slave wheels 113 is reduced, the transmission ratio of the synchronous assembly 11 is ensured, the load capacity of the synchronous assembly 11 is improved, and the push plate 14 can act on the pallet in a timely and accurate manner. As another real-time method, the synchronous assembly 11 can be a sprocket assembly.

[0027] The output shaft of the driving motor 13 is connected to the synchronous shaft 12 to drive the synchronous shaft 12 to rotate. The driving wheel 112 is connected to the synchronous shaft 12 through a bearing. A plurality of driving wheels 112 are arranged at intervals. The interval between the driving wheels 112 is greater than the width or length of the pallet, so that the pallet moves along the length direction of the synchronous belt 111 and between the two synchronous belts 111 to achieve steering under the action of the push plate 14. Preferably, spacers 122 are arranged on both sides of the driving wheel 112 to limit the driving wheel 112. The spacers 122 are fixedly arranged on the synchronous shaft 12. The end face of the spacer 122 is set with a gap between the end face of the driving wheel 112 to prevent the driving wheel 112 from moving on the synchronous shaft 12, causing the synchronous belt 111 to separate from the driving wheel 112.

[0028] Furthermore, it also includes a support plate 121 and a support 123. The support plate 121 is used to support the synchronous shaft 12 and the driving wheel 112 thereon. The support plate 121 is arranged at both ends of the synchronous shaft 12 and the middle of the synchronous shaft 12 to support and stabilize the synchronization and reduce the radial shaking that occurs during the rotation of the synchronous shaft 12. The support 123 is used to support the support rod 124 and the driven wheel 113 thereon. A groove is arranged in the middle of the support 123, and support holes are arranged on both side walls of the groove. The support rod 124 is horizontally placed in the groove, and both ends of the support rod 124 are rotatably arranged in the support holes. The support rod 124 is connected to the driven wheel 113.

[0029] Embodiment 1

[0030] In the first embodiment, the installation position relationship between the push plate mechanism 10 and the first conveying mechanism 20 is as follows: Figures 4 to 6 As shown, the projections of the tray pushing mechanism 10 and the first conveying mechanism 20 on the conveying surface of the first conveying mechanism 20 partially overlap, and the projections of the tray pushing mechanism 10 and the first conveying mechanism 20 in the vertical direction partially overlap.

[0031] The first conveying mechanism 20 includes a plurality of first conveying rollers 21 which are arranged in parallel and at intervals. The central axes of the plurality of first conveying rollers 21 are located on the same plane. End plates 22 are arranged on both sides of the first conveying rollers 21. Both ends of the first conveying rollers 21 are rotatably arranged on the end plates 22. The first conveying rollers 21 can be driven to rotate so that the pallet located on the first conveying rollers 21 can move linearly along the length direction of the end plates 22.

[0032] Specifically, the driven pulley 113 is arranged between two adjacent first conveying rollers 21. The length direction of the synchronous belt 111 is parallel to the central axis of the first conveying roller 21, so that the conveying direction of the first conveying mechanism 20 is perpendicular to the conveying direction of the synchronous assembly 11. The inner belt surface of the synchronous belt 111 above the driving pulley 112 is higher than the conveying surface of the first conveying mechanism 20. The pushing plate 14 is located above the first conveying roller 21. The inner belt surface of the synchronous belt 111 below the driving pulley 112 is not higher than the conveying surface of the first conveying mechanism 20, so that in the vertical direction, the synchronous assembly 11 and the first conveying mechanism 20 partially overlap, so as to reduce the range occupied by the pushing plate mechanism 10 and the first conveying mechanism 20 in the height direction.

[0033] The driven pulley 113 and the driving pulley 112 are respectively arranged close to both ends of the first conveying roller 21. Among them, the driven pulley 113 is located inside the first conveying mechanism 20 and between the two first conveying rollers 21, and the driving pulley 112 is located outside the first conveying mechanism 20. A plurality of through holes 221 are arranged on the end plate 22 on the side close to the driving pulley 112 to avoid the synchronous belt 111. The synchronous belt 111 is arranged corresponding to the through holes 221. The synchronous belt 111 below the driving pulley 112 passes through the through holes 221 to connect the driving pulley 112 and the driven pulley 113. By arranging the driven pulley 113 and the driving pulley 112 close to both ends of the first conveying roller 21, in the plane, the synchronous assembly 11 and the first conveying mechanism 20 partially overlap, so as to reduce the range occupied by the pushing plate mechanism 10 and the first conveying mechanism 20 in the plane.

[0034] The working process of this embodiment is as follows: The tray is located on the first conveying roller 21, and the first conveying roller 21 rotates to convey the tray. When the tray moves below the synchronous belt 111, the driving motor 13 is actuated, the synchronous rod rotates to drive the synchronous belt 111 to move, the synchronous belt 111 drives the pushing plate 14 to move, and the pushing plate 14 pushes the tray to move, so that the tray moves perpendicular to the conveying direction of the first conveying mechanism 20, realizing the turning of the tray. The pushing plate continues to move to push the tray out from between the two synchronous belts 111.

[0035] Further, to avoid friction between the synchronous belt 111 and the first conveying roller 21 during operation, a certain gap should be maintained between the two outer side walls of the support 123 and the two first conveying rollers 21, and the gap is greater than 5 mm.

[0036] In this embodiment, since the upper and lower belt surfaces of the synchronous belt 111 are respectively located above and below the conveying surface of the first conveying mechanism 20, the tray passes between the upper and lower belts of the synchronous belt 111, and the pushing plate 14 is located above the first conveying roller 21 to push the tray to move. To avoid friction between the tray and the outer circumferential surface of the first conveying roller 21 during the movement of the tray, a plurality of avoiding grooves 141 are arranged on the side end surface of the pushing plate 14 facing the first conveying roller 21. The avoiding grooves 141 are semicircular, as Figure 6As shown, the center distance between several avoidance grooves 141 is the same as the center distance between two adjacent first conveying rollers 21. Further, a rubber pad is provided in the avoidance groove 141 to reduce the wear of the first conveying roller 21 caused after the avoidance groove 141 contacts the first conveying roller 21.

[0037] It should be noted that in this embodiment, since the tray passes between the upper and lower belts of the synchronous belt 111, in order for the push plate 14 to act on the tray, at least a part of the push plate 14 is located below the upper belt of the synchronous belt 111. That is, under the influence of the structure of the push plate 14, the synchronous belt 111 cannot complete a full circle of movement around the driven wheel 113 and the driving wheel 112. Therefore, in this embodiment, the rotation direction of the synchronous shaft 12 is bidirectional, and the push plate 14 makes a reciprocating movement. When moving the tray, the push plate 14 advances; when the tray leaves the tray mechanism, the push plate 14 retreats and waits to push the next tray.

[0038] Embodiment 2

[0039] In Embodiment 2, the installation position relationship between the tray pushing mechanism 10 and the first conveying mechanism 20 is as Figure 7 shown. The upper and lower belt surfaces of the synchronous belt 111 are respectively located above and below the first conveying roller 21. The diameters of the driven wheel 113 and the driving wheel 112 should be greater than the thickness of the first conveying roller 21, and the push plate 14 makes a reciprocating movement to push the tray.

[0040] Embodiment 3

[0041] In Embodiment 2, the installation position relationship between the tray pushing mechanism 10 and the first conveying mechanism 20 is as Figure 8 shown. The synchronous belt 111 is entirely located above the first conveying roller 21. The push plate 14 is located on the outer belt surface of the synchronous belt 111, and the push plate 14 can push the tray by making a reciprocating movement or a one-way movement.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
