Description

Technical Field

[0001] The utility model relates to the technical field of material lines, in particular to a pallet with a buffer stopper. Background Art

[0002] The logistics line, also known as the logistics production line, is a system organized in the form of assembly line operations; the pallet conveyor belt is a key component of the logistics line, mainly used to transport palletized goods from one place to another; through the pallet conveyor belt, materials and products can be quickly and accurately transported on the logistics line, thereby improving logistics efficiency.

[0003] At present, during the use of pallet conveyor belts, the use of pallets requires the use of positioning stop structures, so that the pallets can be stopped in the appropriate position so that the goods can be transferred to the pallets; however, in the prior art, the common stop devices are mostly pneumatic buffer or hydraulic buffer types. Although these devices can reduce the impact force of the pallet to a certain extent, in actual use, since the pallet still retains a certain amount of kinetic energy after colliding with the stop device, and the principle of force interaction, the pallet often rebounds after being stopped. This rebound situation will not only cause deviations in the accuracy of pallet positioning, but may also have an adverse effect on subsequent loading and unloading operations. For example, inaccurate pallet positioning may cause the goods to be placed untidy, or even cause the goods to fall or be damaged, which will affect the efficiency and safety of the entire logistics process. In view of this, we propose a pallet with a buffer stop. Utility Model Content

[0004] In order to solve the above-mentioned problem, the utility model provides a pallet with a buffer stopper.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] The pallet belt buffer stopper comprises a pallet conveyor belt, wherein the pallet conveyor belt comprises a frame, a pallet capable of horizontal movement is also mounted at the opening of the frame, and a limit block is fixed at the bottom end of the pallet;

[0007] A buffer stop mechanism is provided below the tray; the buffer stop mechanism comprises a vertical plate fixed to the bottom of the frame, a groove is provided at the top rear end of the vertical plate, a reversible limit seat is provided in the groove, a first spring for pressing against the limit seat is fixed at the bottom of the groove; a pin shaft hinged to the vertical plate is installed at the rear end of the limit seat, and a check block for limiting the limit block to prevent the tray from rebounding is installed at the top of the limit seat;

[0008] A connecting seat is fixed at the front end of both side walls of the vertical plate, and a sliding cavity is opened inside the connecting seat. Slide blocks are slidably installed in the sliding cavity. Connecting rods are connected with coaxial keys on the slide blocks, and the ends of the connecting rods are extended to the outside. A second spring for tightening the connecting seat is installed at the rear end of the connecting rod; a bearing plate is fixed between the front ends of the two connecting rods, and a lifting plate is provided above the bearing plate. Two blocks for stopping the pallet are installed on the top of the lifting plate, and two electric cylinders for driving the lifting plate to rise and fall are installed at the bottom of the bearing plate.

[0009] Furthermore, a baffle is coaxially fixed at the rear end of the connecting rod, and the diameter of the baffle is larger than the diameter of the connecting rod.

[0010] Furthermore, a limiting plate is fixed at the front end of the limiting seat, and the limiting plate, the limiting seat and the check block are an integrally formed structure.

[0011] Furthermore, the overall shape of the groove is narrow at the top and wide at the bottom, and the limiting plate can move inside the groove.

[0012] Furthermore, the lifting plate and the stopper are an integrally formed structure, and both the lifting plate and the stopper are made of galvanized steel.

[0013] Furthermore, the front end surface of the tray is fixedly connected to two pads by bolts, and the pads are made of rubber material.

[0014] Furthermore, the cross-sectional shapes of the limit block and the check block are both right-angled triangle shapes, and the limit block and the check block are located on the same vertical plane.

[0015] Furthermore, the front end surface of the connecting seat is provided with a sliding hole, and the rear end surface of the bearing plate is provided with a sliding rod slidably connected to the sliding hole.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] By setting up a buffer stop mechanism: when the electric cylinder drives the lifting plate to rise, the lifting plate drives the stop block to rise, and when the front end of the pallet contacts the stop block, the slider moves along the sliding cavity under the action of kinetic energy, thereby compressing the spring. Under the elastic action of the spring, the kinetic energy of the pallet can be buffered. At the same time, when the limit block passes the check block, the check block is reset and protrudes to the rear of the limit block. Under the restriction of the check block on the limit block, the pallet is unlikely to rebound. This design can not only achieve a buffer stop for the pallet, but also prevent the pallet from rebounding, thereby ensuring the accuracy of the pallet's stop position, which is beneficial to subsequent loading and unloading operations.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] This embodiment provides a technical solution:

[0029] See also Figure 1-Figure 6, a pallet belt buffer stopper comprises a pallet conveyor belt 1, and the pallet conveyor belt 1 comprises a frame 10, and a pallet 11 which can move horizontally is also installed at the opening of the frame 10, and a limiting block 111 is fixed at the bottom end of the pallet 11; a buffer stop mechanism 2 is provided below the pallet 11; the buffer stop mechanism 2 comprises a vertical plate 20 fixed to the bottom of the frame 10, and a groove 201 is provided at the top rear end of the vertical plate 20, and a reversible limiting seat 22 is provided in the groove 201, and a first spring 21 for pressing against the limiting seat 22 is fixed at the bottom of the groove 201; a pin shaft 223 hinged to the vertical plate 20 is installed at the rear end of the limiting seat 22, and a limiting block 111 is installed on the top of the limiting seat 22 to prevent the pallet 11 from rebounding check block 222; connecting seats 23 are fixed at the front ends of both side walls of the vertical plate 20, and a sliding cavity 231 is opened inside the connecting seat 23, and a slider 24 is slidably installed in the sliding cavity 231, and a connecting rod 25 is coaxially keyed on the slider 24, and the ends of the connecting rod 25 are all extended to the outside, and a second spring 26 for tightening the connecting seat 23 is installed at the rear end of the connecting rod 25; a bearing plate 27 is fixed between the front ends of the two connecting rods 25, and the bearing plate 27 is fixedly connected to the connecting rod 25 by bolts, and a lifting plate 29 is provided above the bearing plate 27, and two blocks 291 for stopping the tray 11 are installed on the top of the lifting plate 29, and two electric cylinders 28 for driving the lifting plate 29 to rise and fall are installed at the bottom of the bearing plate 27.

[0030] In this embodiment, a baffle 251 is coaxially fixed at the rear end of the connecting rod 25, and the diameter of the baffle 251 is larger than the diameter of the connecting rod 25. The setting of the baffle 251 plays a limiting role on the second spring 26.

[0031] In this embodiment, a limiting plate 221 is fixed at the front end of the limiting seat 22, and the limiting plate 221, the limiting seat 22 and the check block 222 are an integrated structure. The setting of the limiting plate 221 is conducive to the downward flipping of the limiting seat 22, and can also prevent the limiting seat 22 from excessively flipping upward and falling out of the groove 201, thereby ensuring the limiting effect of the check block 222 on the limiting block 111.

[0032] In this embodiment, the overall shape of the groove 201 is narrow at the top and wide at the bottom, and the limiting plate 221 can move inside the groove 201. The groove 201 of this design has a limiting effect on the movement of the limiting seat 22, which is conducive to the free downward flipping of the limiting seat 22 and can also prevent the limiting seat 22 from excessively flipping upward and falling out of the groove 201.

[0033] In this embodiment, the lifting plate 29 and the stopper 291 are integrally formed, and both the lifting plate 29 and the stopper 291 are made of galvanized steel. The integrally formed lifting plate 29 and the stopper 291 have better connection strength, ensure the stability of the lifting plate 29 and the stopper 291, and ensure the stopping effect of the lifting plate 29 and the stopper 291 on the tray 11.

[0034] In this embodiment, the front end surface of the tray 11 is fixedly connected with two pads 112 by bolts, and the pads 112 are made of rubber material. The rubber pads 112 can reduce the vibration caused by the collision between the tray 11 and the stopper 291, and play a protective role for the tray 11.

[0035] In this embodiment, the cross-sectional shapes of the limit block 111 and the check block 222 are both right-angled triangles, and the limit block 111 and the check block 222 are located on the same vertical plane. When the tray 11 moves horizontally, the limit block 111 passes the check block 222, and the check block 222 is squeezed and can move downward. When the tray 11 is stopped, the tray 11 cannot rebound due to the obstruction of the check block 222.

[0036] In this embodiment, the front end surface of the connecting seat 23 is provided with a sliding hole 232, and the rear end surface of the carrying plate 27 is provided with a sliding rod 271 slidably connected to the sliding hole 232. The arrangement of the sliding rod 271 and the sliding hole 232 guides the horizontal movement of the carrying plate 27, thereby ensuring the stability and smoothness of the carrying plate 27.

[0037] It should be added that the connection seat 23 in this embodiment is fixedly connected to the vertical plate 20 by bolts, and the vertical plate 20 is fixedly connected to the inner bottom of the frame 10 by bolts. The bolt fixing method ensures the installation stability and reliability of the connection seat 23 and the vertical plate 20.

[0038] During specific use, the user first turns on the power of the electric cylinder 28, and the electric cylinder 28 starts to work. The piston rod of the electric cylinder 28 extends and drives the lifting plate 29 and the block 291 to move upward. When the tray 11 moves to the block 291, the tray 11 collides with the block 291. Under the action of kinetic energy, the block 291 is impacted and moves forward, and drives the connecting rod 25 and the slider 24 to move forward. At this time, the slider 24 slides along the sliding cavity 231, and the second spring 26 is compressed by the baffle 251. Under the elastic action of the second spring 26, the impact force is gradually weakened. With the reset of the second spring 26, the block 291 pushes the tray 11 to move backward. When the limit block 111 moves to the check block 222, the tray 11 stops moving under the obstruction of the check block 222.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
