Description

Technical Field

[0001] This utility model belongs to the technical field of kiln equipment, and specifically relates to a palletless packaging circulating conveyor. Background Technology

[0002] After brick processing, stacking and packaging are required. Stacking and packaging can be done on pallets or not. For example, patent application number CN202110697399.3 discloses a palletless block stacking and packaging production line, including a block transfer hoist, a dual-mode conveyor, a block rotating hoist, and a pallet circulating conveyor. The block rotating hoist is used to transfer two rows of blocks from the dual-mode conveyor to the pallet of the pallet circulating conveyor. A block arranging and stacking device is provided on one side of the pallet circulating conveyor. The block arranging and stacking device includes a block clamping mechanism and a block stacking mechanism. The block clamping mechanism is located above the block stacking mechanism. The block clamping mechanism includes a support, a clamping frame, a lifting frame, and two grippers. Driven by a transfer power source, the lifting frame is slidably mounted on the support. Driven by a lifting power source, the lifting frame is slidably mounted on the clamping frame. The lifting frame is equipped with a guide shaft. Two grippers are slidably mounted on the guide shaft by a combined power source. Each gripper includes a gripper base and two clamping blocks hinged to both ends of the gripper base. The clamping blocks are connected to a clamping power source that drives the clamping blocks to rotate. The block stacking mechanism includes a support, a stacking hopper, a lifting seat, a vertical power source, and a rotary power source. The stacking hopper is rotatably mounted on the support by a rotary power source. The lifting seat is slidably mounted inside the stacking hopper by a vertical power source.

[0003] To achieve palletless packaging, a palletless packaging circulating conveyor is required. For example, patent application number CN201822203930.3 discloses a circulating conveyor for palletless packaging, including a drive wheel device, a driven wheel device, a frame, and two chains. The drive wheel device and the driven wheel device are respectively fixed to both ends of the frame and connected by the two chains, which are arranged in parallel. It also includes multiple support component groups, each positioned between the two chains, with both ends of each support component group fixed to the two chains. Furthermore, it includes a support mechanism for supporting the weight of the support components. The support mechanism includes support wheels and support rods. Each support component has a support wheel fixed to both ends, located on the side of the support component. The support rods are arranged one-to-one with the chains and fixed to the frame along the transmission direction. The support rods are located below the chains. When the support component group rotates to below the conveyor, the support wheels slide on the support rods.

[0004] Existing palletless packaging conveyor systems include a frame, a chain assembly arranged in a front-to-back direction, multiple pallet assemblies arranged side-by-side on the chain assembly, two drive wheels at both ends of the chain assembly and mounted on the frame, and a chain support structure for supporting the chain assembly. The chain assembly includes two chains arranged side-by-side, the pallet assembly includes multiple support bars arranged side-by-side, and the chain support structure supports the upper part of the chain. While supporting the chain, the chain support structure also supports the upper pallets. This structure has the following problems: First, for the lower pallet, the chain is located on the upper side of the support bar and cannot provide support, resulting in unstable chain conveying; Secondly, for the chain support structure, the weight of the pallet assembly and the brick stack on it is all borne on the chain support structure, resulting in severe wear on both the chain and the chain support structure; Third, the chain can slide left and right on the chain support structure, causing the support bar to slide left and right, which in turn leads to unstable conveying.

Detailed Implementation

[0017] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0018] Example 1 See Figure 1-5Example 1 provides a palletless packaging circular conveyor, including a frame 1, a chain assembly, a chain support structure 4, two drive wheels 3, and multiple pallet assemblies 2. The frame 1 is arranged in a front-to-back direction and is specifically a frame structure. The two drive wheels 3 are respectively located at the front and rear ends of the frame 1 and are arranged in a left-to-right direction, one of which is the active drive wheel (the other is the passive drive wheel). Specifically, the drive wheel 3 includes a rotating shaft and two sprockets arranged side by side on it (coaxial with the rotating shaft), and the rotating shaft is arranged in a left-to-right direction on the frame 1. The rotating shaft of one of the drive wheels 3 is rotatably connected to a drive motor to serve as the active drive wheel. The chain assembly is arranged in a front-to-back direction, with its front and rear ends respectively wrapped around the two drive wheels 3, and includes two chains 5 arranged side by side. Specifically, the ends of the two chains 5 are respectively wrapped around the two sprockets, and the chains 5 are arranged in a front-to-back direction. Multiple pallet assemblies 2 are arranged side by side on the chain assembly; the pallet assembly 2 includes multiple (preferably more than or equal to 4) support strips 21 arranged side by side. The support bar 21 is arranged in a left-right direction, with its left and right parts mounted on two chains 5. It is horizontally positioned, and the side furthest from the chains 5 may have multiple grooves arranged side-by-side (in a front-back direction). Specifically, the upper part of the chain 5 has N pallet assemblies 2 arranged side-by-side to form an upper pallet (moving from front to back), and the lower part has multiple pallet assemblies 2 arranged side-by-side to form a lower pallet (moving from back to front). N is an integer greater than or equal to 4. For the upper pallet: the support bar 21 is located on the upper side of the chain 5; for the lower pallet: the support bar 21 is located on the lower side of the chain 5. The chain support structure 4 is located on the upper part of the frame 1, and it supports the chain 5 (i.e., the upper part of the chain 5) of the upper pallet. It includes two upper support beams 15 arranged side-by-side. Two upper support beams 15 are located on the lower side of the upper part of the two chains 5 respectively, and both are mounted on the frame 1 in the front-back direction; the upper parts of the two chains 5 are slidably mounted on the two upper support beams 15 respectively.

[0019] The bracket 1 has two slide rails 11 in the middle and two lower support beams 12 at its bottom. The slide rails 11 and lower support beams 12 are arranged in a front-to-back direction. The arrangement of the slide rails 11, lower support beams 12, and upper support beams 15 at their front and rear ends ensures that the chain 5 can turn normally at the drive wheel 3. For example, there should be a certain distance (e.g., 100mm) between the front end of the slide rail 11 and the front drive wheel 3. The two slide rails 11 are arranged back-to-back, and the two lower support beams 12 are arranged side-by-side. The front and rear support bars 21 of the pallet assembly 2 are each equipped with pulleys 22 (too many should be avoided as they increase friction and make turning difficult). The pulleys 22 are arranged in a left-to-right direction and are located in the middle of the support bar 21 closest to the chain 5. Specifically, for the upper pallet: the pulley 22 is located in the lower middle of the support bar 21; for the lower pallet: the pulley 22 is located in the upper middle of the support bar 21. Two slide rails 11 are located between the upper and lower pallets, respectively supporting and guiding them. The upper pallet's pulley 22 slides on the upper side of the slide rail 11 (via pulley 22), while the lower pallet's pulley 22 slides on the lower side of the slide rail 11 (via pulley 22). Each support bar 21 has a support roller 23 at both ends in the left-right direction. Two lower support beams 12 are located below the support rollers 23 at both ends of the lower pallet, with the support rollers 23 sliding on their corresponding lower support beams 12. Specifically, the pulleys 22 have a larger diameter, requiring them to move only back and forth on the slide rail 11; the support rollers 23 have a smaller diameter and can be bearings.

[0020] Specifically, in this embodiment of the present invention, both the lower support beam 12 and the upper support beam 15 are rectangular tube structures.

[0021] Example 2 See Figure 3 Example 2 provides a palletless packaging circulating conveyor, whose structure is basically the same as that of Example 1, except that: in this example, the slide rail 11 is an angle iron rail with the apex pointing upwards or downwards; specifically, for the upper slide rail 11, the apex points upwards; for the lower slide rail 11, the apex points downwards. The pulley 22 is slidably disposed on the apex of the angle iron rail and has an annular groove on its circumference that mates with the apex.

[0022] Example 3 See Figure 1-5Example 3 provides a palletless packaging circulating conveyor, whose structure is basically the same as that of Example 1, except that: in this example, the frame 1 is provided with multiple upper crossbeams 13 for mounting slide rails 11, and multiple lower crossbeams 14 at its bottom for mounting lower support beams 12. The multiple upper crossbeams 13 are arranged side by side, all along the left-right direction, with their left and right ends located on the frame 1 (specifically on the left and right frame edges), between the upper and lower pallets. Two slide rails 11 are respectively located at the upper middle and lower middle of the multiple upper crossbeams 13. The multiple lower crossbeams 14 are arranged side by side, all along the left-right direction, with their left and right ends located on the frame 1 (specifically on the left and right frame edges). Two lower support beams 12 are respectively located at the upper left and upper right ends of the multiple lower crossbeams 14. Specifically, a lower crossbeam 14 is installed directly below the upper crossbeam 13, and the distance between two adjacent upper crossbeams 13 is 0.5-2.0m.

[0023] Example 4 See Figure 3 Example 4 provides a palletless packaging circulating conveyor, whose structure is basically the same as that of Example 1, except that: in this example, the upper side of the upper support beam 15 is detachably provided with a wear-resistant layer 16 (e.g., fixed by bolts). The upper part of the chain 5 is slidably disposed on the wear-resistant layer 16. Specifically, the wear-resistant layer 16 can be a rectangular metal strip arranged in the front-back direction (requiring wear resistance, it can be composed of multiple front-back splicing sections).

[0024] Example 5 See Figure 1-2 Example 5 provides a palletless packaging circular conveyor, whose structure is basically the same as that of Example 1, except that N in this example is 5 (each pallet assembly 2 constitutes a workstation). Along the conveying direction of the pallet assembly 2, there are sequentially a palletizing workstation, a transverse binding workstation, a longitudinal binding workstation, a front forklift unloading workstation, and a rear forklift unloading workstation. The transverse binding workstation and the longitudinal binding workstation can be interchanged. The two forklift unloading workstations ensure that the products can be transported, similar to the prior art.

[0025] Example 6 Example 6 provides a palletless packaging circular conveyor, whose structure is basically the same as that of Example 1, except that: the total length of the frame 1 in this example is 13.68m, the front-to-back length of the chain 5 is 13.42m; the distance between the front and rear ends of the pallet assembly 2 is 965mm, the width in the left-to-right direction is 1034mm, and each pallet assembly 2 includes 5 support strips 21. The distance between two adjacent upper crossbeams 13 is 1130mm. The width of the support strip 21 is 80mm. The distance between the two chains 5 is 800mm.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
