Description

Transmission device and logistics equipment

Technical Field

The utility model relates to the technical field of logistics storage, in particular to a conveying device and logistics equipment.

Background

In the field of logistics storage, trays are important tools for material transfer. In chemical warehouse systems, equipment such as stackers and RGVs (rail guided vehicles) are often used to pick and place pallets. The operating efficiency and accuracy of these devices have a decisive influence on the stability and efficiency of the overall warehouse system. The placement accuracy of the tray has a particularly remarkable influence on the running stability of the equipment. If the trays are placed at a different angle on the conveyor, this may cause difficulty in picking and placing the trays by the stacker or RGV, and even may cause deformation of the load-bearing materials. Once the material is deformed, the quality of the material is affected, and the material is possibly damaged, so that the logistics cost is increased and the resource is wasted. Existing conveyor systems are typically driven by a single motor, with the overall direction and speed of movement of the conveyor remaining consistent. When the tray passes through a turning position, the deviation of the placing position of the tray can be caused due to the action of inertia and centrifugal force. In addition, if the material on the conveyor belt is unevenly distributed, the trays may also be inclined or offset during the conveyance. However, the present conveyor system cannot adjust the placement position of the tray. When deviation appears in the position of putting of tray, usually need the staff to put the tray right by hand, this has not only increased the human cost, still probably influences the operating efficiency of whole warehouse system.

The principles and structures of the present utility model are described in detail below with reference to the drawings and the examples.

A conveying device comprises a conveying belt 1, a tray 4 for bearing materials is placed on the conveying belt 1, the conveying belt 1 comprises a plurality of chain structures, and a frequency converter which is arranged corresponding to each chain structure and used for changing the conveying speed of the chain structure, so that the position of the tray 4 can be adjusted on the conveying belt 1.

In a specific embodiment, as shown in fig. 1 to 5, a conveying device according to the present application is applied to a three-dimensional warehouse, the main body of which is a conveyor belt 1, and in this conveying device, a tray 4 carrying materials is placed on the conveyor belt 1 and moves along with the movement of the conveyor belt 1. In this way, the pallet 4 enables the transport of the material, thus completing the task of transporting the material in the logistics apparatus. The conveyor belt 1 comprises a number of chain structures by means of which the conveyor belt 1 and the trays 4 are driven.

It is noted that each chain structure is provided with a corresponding frequency converter for varying the conveying speed of its corresponding chain structure. By controlling the frequency converter, the conveying speed of each chain structure can be independently adjusted. Thus, when the tray 4 moves on the conveyor belt 1, the position of the tray 4 on the conveyor belt 1 can be adjusted by adjusting the conveying speed of each chain structure.

Specifically, when the conveyor belt 1 is started, the tray 4 moves along with the movement of the conveyor belt 1. In this way, the material on the pallet 4 can be driven and transported along the advancing direction of the conveyor belt 1. In this process, both the position and the speed of the pallet 4 are affected by the conveyor belt 1. When the pallet 4 on the conveyor belt 1 passes through the corner, the pallet 4 may be subjected to a lateral force due to inertia and centrifugal force, resulting in deviation of the placement position of the pallet 4. In other cases, the placement position of the trays 4 may also be affected by maldistribution of the material carried in the trays 4. If the material is unevenly distributed in the trays 4, it may cause the trays 4 to tilt or shift during the conveying process. Such tilting or shifting not only affects the stability of the trays 4 on the conveyor belt 1, but also may cause damage to the material. This is because when the placement position of the tray 4 is deviated, the stacker 5 or the rail shuttle in the three-dimensional warehouse may encounter difficulty in picking and placing the tray 4. Due to inaccurate positions of the trays 4, the stacker 5 or the shuttle may not accurately take or put materials from or into the trays 4, and if the tray 4 is not positioned, the stacker 5 or the shuttle may damage the materials carried by the tray 4 when taking and putting the tray.

If the pallet 4 is too much tilted, the stacker 5 or shuttle may knock it down or break during the material handling, resulting in greater losses.

In the prior art, when the tray 4 is offset, it is generally necessary for a worker to manually move the tray 4 to adjust its position. The method is not only low in efficiency, but also increases the labor intensity of workers.

However, with the conveying device proposed by the present application, automatic adjustment of the position of the tray 4 can be achieved by adjusting the conveying speed of the respective chain structures. Specifically, the transmission device provided by the application comprises a plurality of chain structures, and each chain structure is correspondingly provided with a frequency converter. When the tray 4 is deviated, the rotation speed of the motor 23 of each chain structure can be adjusted through the frequency converter, so that the conveying speed of each chain structure is controlled, and the position of the tray 4 is adjusted. For example, if the tray 4 is offset to the left, a right correction force may be generated by controlling the conveying speed of the chain structure contacting the right of the tray 4 to be slightly lower than that of the chain structure contacting the left of the tray 4, so that the tray 4 is corrected while continuing to move in the moving direction of the conveyor belt 1.

In a word, the transmission device provided by the application realizes the correction of the position of the tray 4 by controlling the transmission speed of each chain structure, and the automatic adjustment method not only improves the working efficiency, but also reduces the labor intensity of staff and avoids the risk of misoperation. Through ensuring the accurate placement of the tray 4, the material on the tray 4 can be more smoothly fetched and placed by the stacker 5 and the rail shuttle, and deformation or damage of the material when fetched and placed due to the deviation of the placement position of the tray 4 is avoided, so that the working efficiency of the whole logistics transportation process is improved.

Further, the chain structure comprises a first chain structure 2 and a second chain structure 3 which are arranged in parallel at intervals, and the first chain structure 2 and the second chain structure 3 are respectively positioned at two sides of the conveyor belt 1.

Further, the chain structure further comprises a third chain structure arranged in parallel with the first chain structure 2 and the second chain structure 3 at intervals, and the first chain structure 2 and the second chain structure 3 are symmetrically arranged about the third chain structure.

Further, the chain structure comprises a chain 22, a gear 21 and a motor 23, wherein the gear 21 is meshed with the chain 22, and the motor 23 is connected with the gear 21.

In a specific embodiment, as shown in fig. 2-5, the chain structure is provided on a stand to ensure stability during operation. A motor 23 is fixed to this bracket, and the gear 21 and the motor 23 are connected together. When the motor 23 is started, the gear 21 rotates with it, converting the power of the motor 23 into mechanical energy. The chain 22 is wound on the gear 21, and the chain 22 and the gear 21 are engaged with each other, ensuring the smoothness of the power transmission of the whole chain structure. The pallet 4 is placed above the support and in contact with the chain 22, and when the gear 21 rotates, the chain 22 moves with it, transmitting power to the pallet 4, so that the pallet 4 moves with it.

By means of the arrangement, whenever a material is required to be transferred from one position to another, the tray 4 moves along with the movement of the chain 22 only by starting the motor 23, the material to be transferred is placed in the tray 4, and the material transfer function of the transfer device can be achieved through the movement of the multiple chain structures.

In the transmission device according to the application, each chain structure is provided with a motor 23, which motors 23 are controlled by a frequency converter. The frequency converter is electrically connected with the motors 23, and frequency conversion is in one-to-one correspondence with the number of the motors 23, which means that the rotation speed of each motor 23 can be controlled by the frequency converter, so that different chain structures can have different conveying speeds.

The core function of the frequency converter is to adjust the rotational speed of the motor 23. By varying the output frequency of the frequency converter, the rotational speed of the motor 23 can be varied, thereby effecting control of the conveying speed of the chain structure. Thus, when the tray 4 is shifted, the adjustment of the position of the tray 4 can be achieved by adjusting the conveying speed of the chain structure in contact with the tray 4.

To achieve more accurate correction, multiple frequency converters may be used to control the conveying speed of multiple chain structures, respectively. By making a speed difference between the conveying speeds of the plurality of chain structures, a correction force can be generated to bring the pallet 4 back to the normal position while continuing to move in the direction of movement of the conveyor belt 1.

For example, as shown in fig. 6, the conveying device has two chain structures, including a first chain structure 2 and a second chain structure 3 respectively disposed at two sides of the conveyor belt 1, a tray 4 for carrying materials is disposed above the first chain structure 2 and the second chain structure 3, when the tray 4 is offset toward the first chain structure 2, the conveying speed of the first chain structure 2 can be controlled to be larger than the conveying speed of the second chain 22, so as to generate a correcting force toward the direction of the second chain structure 3, and when the placement position of the tray 4 is recovered, the running speeds of the first chain structure 2 and the second chain structure 3 are controlled to be consistent, so as to realize correction of the position of the tray 4.

In other embodiments, the transmission device provided by the application may further be provided with three chain structures, including a first chain structure 2 and a second chain structure 3 respectively disposed on two sides of the conveyor belt 1, and a third chain structure disposed in the middle of the conveyor belt 1, where the first chain structure 2, the second chain structure 3 and the third chain structure are disposed parallel to each other, and the first chain structure 2 and the second chain structure 3 are symmetrical with respect to the third chain structure. When the tray 4 is offset, a speed difference can be generated by controlling the conveying speeds of the first chain structure 2 and the second chain structure 3, and the placement position of the tray 4 can be adjusted. The third chain structure is located in the middle of the conveyor belt 1 and has the main function of ensuring the overall conveying speed of the conveyor. The conveying speed of the third chain structure can be adjusted as required to ensure the stability and the working efficiency of the whole conveying device, so that the conveying device has higher flexibility and adaptability.

In summary, this kind of transmission device realizes the correction function to the position of the tray 4 by controlling the conveying speeds of a plurality of chain structures respectively using a plurality of frequency converters. The design avoids the risk of damage caused by the position deviation of the tray 4 during material storage and retrieval, and improves the accuracy and the working efficiency of the whole transmission flow.

Further, a sensing unit group for detecting the position of the tray 4 is also provided on the conveyor belt 1.

Further, the sensing unit group includes a first sensor 11 and a second sensor 12 disposed at both sides of the entrance of the conveyor belt 1.

Further, the sensing unit group includes a third sensor 13 and a fourth sensor 14 provided at both sides of the exit of the conveyor belt 1.

Further, the sensor of the sensing unit group is an infrared sensor.

In a specific embodiment, as shown in fig. 6, a sensing unit group for detecting the position of the tray 4 is further provided on the conveyor belt 1, and the sensing unit group is composed of a plurality of infrared sensors. The tray 4 is put in from the entrance of conveyer belt 1, and the both sides of entrance have set up first sensor 11 and second sensor 12 respectively, and tray 4 takes out from the exit of conveyer belt 1, and the both sides of exit have set up third sensor 13 and fourth sensor 14 respectively.

Specifically, the first sensor 11 and the second sensor 12 are symmetrically arranged, the third sensor 13 and the fourth sensor 14 are symmetrically arranged, and the irradiation directions of the first sensor and the second sensor are perpendicular to the plane of the conveyor belt 1, and the first sensor and the second sensor can irradiate from top to bottom or from bottom to top.

Take as an example a conveyor with two chain structures as shown in fig. 7 to 9; the time when the tray 4 reaches the detection position of the first sensor 11 is detected by the first sensor 11 at the entrance, the time when the tray 4 reaches the detection position of the second sensor 12 is detected by the second sensor 12, when the tray 4 shifts, the tray 4 does not simultaneously reach the detection positions of the first sensor 11 and the second sensor 12, the shift distance difference of the tray 4 can be calculated according to the current rotation speed of the chain 22, and the rotation speeds of the motors 23 of the first chain structure 2 and the second chain structure 3 can be controlled by the frequency converter, so that the distance difference can be compensated by adjusting the transmission speed difference of the first chain structure 2 and the second chain structure 3, and the position correction of the tray 4 is realized.

As shown in fig. 10, the principle of the third sensor 13 and the fourth sensor 14 provided at both ends of the outlet side of the conveyor belt 1 is the same as that described above, and the purpose is to detect whether the tray 4 is offset again when the tray 4 is taken out, and if the tray 4 is still offset, to control the first chain structure 2 and the chain structure 3 to move in the opposite direction, and to adjust the conveying speeds of the first chain structure 2 and the second chain structure 3 to return the tray 4 to the outlet side and to ensure that the tray 4 can be smoothly taken out.

The application also discloses logistics equipment comprising the transmission device. Further, the logistics equipment is a three-dimensional warehouse, and the three-dimensional warehouse comprises a stacker 5 capable of taking and placing trays 4 on the conveyor belt 1 and a rail shuttle. The three-dimensional warehouse is arranged through the transmission device, so that the pallet 4 can be smoothly taken and placed by the stacker 5 and the rail shuttle, damage caused by position deviation of the pallet 4 during material storage and taking is avoided, the failure rate is reduced, and the working efficiency of the whole three-dimensional warehouse is improved.

Compared with the prior art, the automatic adjustment method has the advantages that the position of the tray 4 is corrected by controlling the conveying speed of each chain structure, the working efficiency is improved, the labor intensity of workers is reduced, and the risk of misoperation is avoided. Through ensuring the accurate placement of the tray 4, the material on the tray 4 can be more smoothly fetched and placed by the stacker 5 and the rail shuttle, and deformation or damage of the material when fetched and placed due to the deviation of the placement position of the tray 4 is avoided, so that the working efficiency of the whole logistics transportation process is improved.
