First, the structure of the table 100 according to the embodiment of the present disclosure will be explained with reference to fig. 1 to 3. Fig. 1 schematically illustrates a structural schematic diagram of a workbench 100 according to an embodiment of the present disclosure when an upper end surface of a lifting platform 30 is in a first plane. Fig. 2 schematically illustrates a structural view of the work table 100 when the upper end surface of the lifting platform 30 is in the second plane according to an embodiment of the present disclosure. Fig. 3 schematically shows a side view of the table 100 of fig. 1 from a viewing angle a.

As shown in fig. 1 to 3, the work table 100 includes a frame 10, a table 20, and a lifting platform 30. The elevating platform 30 and the table 20 are installed in the frame 10. Wherein, for example, the lifting platform 30 is adjacent a first side of the table 20. The upper end surface of the elevating platform 30 can move between a first plane and a second plane, wherein the first plane and the second plane are parallel and have a height difference, and the second plane is coplanar with the tabletop 21 of the table 20. The lifting platform 30 is used to move the first object from a first plane to a second plane on which the tabletop 21 of the table 20 is located, wherein the first plane and the second plane are parallel and have a height difference.

The first plane may be, for example, the plane of the conveying surface of the conveying line. In this way, according to the embodiment of the present disclosure, the first object transferred by, for example, the conveying line can be automatically received and conveyed to the height of the tabletop 21 of the table 20, and manual handling is avoided.

The frame 10 may for example comprise feet 11 and supports such as respective cross beams, uprights and vertical bars. The table 20 may include, in addition to the table top 21, a second tier 22 and a third tier 23, for example, for receiving supplies for work.

It is to be understood that the illustration of fig. 1-3 in which the first plane is higher than the second plane is merely illustrative and not limiting. In some embodiments, the first plane may be lower than the second plane. The specific determination is based on the working conditions in the actual application. As long as there is a significant height difference between the first plane and the second plane, in practice, the first object needs to be moved to the table 20 after being transported, and at this time, such cargo lifting transportation can be realized through the work table 100 according to the embodiment of the present disclosure, so as to facilitate the first object to reach the tabletop 21 of the table 20.

According to the embodiment of the present disclosure, the workbench 100 may move the first object from the first plane to the height of the table top 21 of the table 20, so that the problem that a lot of manpower has to be consumed to carry the first object onto the table 20 at the time of warehouse work may be at least partially alleviated, and thus the efficiency of warehouse work such as packing work may be improved, and especially the working efficiency of bulky or heavy goods may be improved.

The first object may be a specific object of a certain type, but also an object of any kind. For example, the first object is an incubator for preserving fresh goods. In recent years, with the rapid development of logistics business, online shopping and internet +, the demand for purchasing fresh goods from internet suppliers is increasing, and meanwhile, the requirements of the buyers for the preservation and transportation of the fresh goods are also increasing. As the preservation of the fresh articles needs to ensure certain requirements of temperature and humidity and the like, the fresh articles generally need to be placed in the incubator with the ice board. The incubator is usually surrounded by, for example, 2 to 4 frozen ice boards, and the incubator is usually large in size. This results in an incubator that is not only bulky but also heavy. In the prior art, the stacked positions of the heat preservation boxes are usually placed near a table manually, however, only a small number of heat preservation boxes can be stored near the table, so that the heat preservation boxes need to be carried to be near the table manually, and time and labor are wasted. By using the workbench 100 according to the embodiment of the disclosure, the incubator can be conveyed from the first plane where the conveying surface of the conveying line is located to the second plane where the tabletop 21 of the table 20 is located, so that manual conveying of the incubator is avoided, physical force consumed by carrying the incubator up and down is saved, and the efficiency of operations such as packing of fresh articles is improved.

According to embodiments of the present disclosure, the lift platform 30 may include a telescoping mechanism 32 and a top plate 33. Wherein. The top plate 33 is horizontally fixed on the top of the telescopic mechanism 32, and the upper surface of the top plate 33 forms the upper end surface of the lifting platform 30. The telescopic mechanism 32 moves the top plate 33 by changing the telescopic movement.

As shown in fig. 1 to 3, the elevating platform 30 includes a first layer plate 31, a telescoping mechanism 32, and a top plate 33. Wherein the first layer plate 31 is horizontally fixed to the frame 10. The bottom of the telescopic mechanism 32 is fixed to the first deck 31. A top plate 33 is horizontally fixed on top of the telescopic mechanism 32. As the telescopic mechanism 32 is expanded and contracted, the upper surface of the top plate 33 forms the upper end surface of the elevating platform 30 and is movable between a first plane and a second plane. For example, a state in which the top plate 33 is in the first plane may refer to the illustration of fig. 1, and a state in which the top plate 33 is in the second plane may refer to the illustration of fig. 2.

According to some embodiments of the present disclosure, the lift platform 30 further includes a base plate 34. The bottom plate 34 is fixed on the first layer plate 31, and the bottom of the telescopic mechanism 32 is fixed on the bottom plate 34. The bottom plate 34 may be located in a local area of the first layer 31 for mounting the pantograph mechanism 32 for reinforcing the support of the pantograph mechanism 32.

The telescoping mechanism 32 may be, for example, a hydraulic telescoping mechanism. The telescopic mechanism 32 may be formed by a plurality of telescopic cylinders and a plurality of telescopic rods. The bottom of the telescopic cylinder can be fixed on the bottom plate 34, the telescopic rod can vertically move in the telescopic cylinder, and the top plate 33 is fixed at the top of the telescopic cylinder and moves up and down along with the telescopic movement of the telescopic rod.

Referring to fig. 1-3, according to an embodiment of the present disclosure, the first plane is higher than the second plane. The table 100 further includes a blocking plate 40, and the blocking plate 40 is installed at a first position in the frame 10, which is located in an interface area of the lifting platform 30 and the table 20. Wherein in the first position the lowermost end of the baffle 40 is at a distance from the first plane that is less than the height of the first object and the lowermost end of the baffle 40 is at a distance from the second plane that is greater than the height of the first object.

The installation position of the blocking plate 40 should be considered enough to perform a limit blocking function on the first object conveyed from the conveyor line when the table 100 is in the state shown in fig. 1, and not to affect the movement of the first object to the table top 21 of the table 20 when the table 100 is in the state shown in fig. 2.

According to an embodiment of the present disclosure, the work table 100 further includes a roller 50, and the roller 50 is mounted to a first edge of the table 20 in the frame 10, the first edge being adjacent to the lifting platform 30. Wherein the axis of the roller 50 is parallel to the table top 21 and is flush with the table top 21. The roller 50 may be an unpowered roller, or may be a motorized roller, or the like.

This roller 50 shown in fig. 1 and 2 is an unpowered roller 50, according to embodiments of the present disclosure. For example, when the lift platform 30 transports the first object to the second plane on which the table top 21 is located (i.e., the table 100 is in the state shown in fig. 2), the worker may push the first object onto the table top 21 along the unpowered rollers 50.

According to an embodiment of the present disclosure, the lift platform 30 further includes a sensor and a control system (the control system is not shown in the figures). The sensor is used to detect a sensing signal of the first object moving to the upper surface of the top plate 33 or moving away from the upper surface of the top plate 33. The control system is used for controlling the telescopic change of the telescopic mechanism 32 according to the sensing signal, and comprises: under the condition that the upper surface of the top plate 33 is in the first plane, after detecting that the first object is stably parked on the upper surface of the top plate 33, controlling the telescoping mechanism 32 to move the top plate 33; and controlling the telescopic mechanism 32 to move the top plate 33 after detecting that the first object is completely separated from the upper surface of the top plate 33 in a case where the upper surface of the top plate 33 is in the second plane. The control system may be, for example, an electrical control system of the lift platform 30.

Referring to fig. 3, the sensor includes a load cell 351 according to an embodiment of the present disclosure. The load cell 351 may be mounted below the top plate 33. More specifically, as shown in fig. 3, the load cell 351 may be installed between the first deck 31 and the bottom deck 34.

According to an embodiment of the present disclosure, the load cell 351 is configured to obtain the sensing signal according to the load bearing signal of the top plate 33. Specifically, the load cell 351 detects a load bearing signal of the top plate 33, and determines that the first object is stably parked on the upper surface of the top plate 33 after the load bearing signal increases to the maximum and is stable; alternatively, after the weight-bearing signal is minimized and stabilized, it is determined that the first object is completely separated from the upper surface of the top plate 33.

According to an embodiment of the present disclosure, the sensor may further include a photosensor 352 in addition to the load cell 351. The photosensor 352 can be mounted in a second position in the frame 10 shown in fig. 1 and 2. In particular, the second position is a distance above the first plane by the height of the first object. For example, as shown in fig. 1-3, the second location may be on the third ply 23. The detection area of the photosensor 352 may be perpendicular to the moving direction of the first object when the top plate 33 is in the first plane. The photoelectric sensor 352 detects a sensing signal, and determines that an object reaching the upper surface of the top plate 33 is a first object when the photoelectric signal is detected, including when the upper surface of the top plate 33 is on the first plane. The photoelectric sensor 352 can determine whether the object reaching the upper surface of the top plate 33 is the first object, so as to avoid frequent expansion and contraction of the expansion mechanism 32 when other objects are placed on the upper surface of the top plate 33. For example, if the worker places a tool or the like in the packing work on the upper surface of the top plate 33, the photoelectric sensor 352 cannot detect the photoelectric signal, and the extension mechanism 32 may not be moved in the extension direction, thereby preventing the ineffective strain of the extension mechanism 32. Therefore, according to the embodiment of the present disclosure, it is possible to determine that the object reaching the upper surface of the top plate 33 is the first object and control the expansion and contraction of the expansion and contraction mechanism 32 after determining that the first object is stably parked by using the double insurance of the weighing sensor 351 and the photoelectric sensor 352, thereby improving the efficiency and the safety of the workbench 100.

Fig. 4 schematically shows a flow chart of a control method for controlling the table 100 according to an embodiment of the present disclosure.

As shown in fig. 4, the control method for controlling the table 100 may include operations S401 to S406 that are cyclically performed, wherein the operations S401, S402, S404, and S405 are conditional judging operations. For these condition determination operations, the next operation in the loop is continued when the condition is satisfied, and the loop stays in the current operation when the condition is not satisfied.

In operation S401, it is determined whether the upper surface of the top plate 33 is in the first plane. The next operation S402 is performed when the upper surface of the top plate 33 is in the first plane, otherwise the loop stays in the current operation to continue waiting.

Then, in operation S402, in a case where the upper surface of the top plate 33 is at the first plane, it is determined whether it is detected that the first object is stably parked on the upper surface of the top plate 33 according to the sensing signals (e.g., sensing signals obtained by the load cell 351 and the photo sensor 352). If yes, the next operation S403 is executed, otherwise, the operation stays in the current operation and continues to wait.

Next, in operation S403, when it is detected that the first object is stably parked on the upper surface of the top plate 33, the telescoping mechanism 32 is controlled to drive the top plate 33 to move toward the second plane.

Then, in operation S404, it is determined whether the upper surface of the top plate 33 is in the second plane. If yes, the next operation S405 is executed, otherwise, the operation stays in the current operation and continues to wait.

Next, in operation S405, in a case where the upper surface of the top plate 33 is in the second plane, it is determined whether it is detected that the first object completely leaves the upper surface of the top plate 33 according to a sensing signal (for example, a sensing signal detected by the load cell 351). If yes, the next operation S406 is executed, otherwise, the operation stays in the current operation and continues to wait.

Then, in operation S406, after detecting that the first object is completely separated from the upper surface of the top plate 33, the telescoping mechanism 32 is controlled to move the top plate 33 until the upper surface of the top plate 33 reaches the first plane.

Thereafter, the control flow returns to operation S401 to enter the next cycle. Repeating this operation, the cyclic control is performed through the condition determination operations of operation S401, operation S402, operation S404, and operation S405, so that the first object can be moved to a height flush with the tabletop 21 through the lifting platform 100 in a cyclic order, and the upper end surface of the lifting platform 30 (i.e., the upper surface of the top plate 33) can be automatically raised to the first plane after the worker pushes the first object 21 away from the upper surface of the top plate 33.

Fig. 5A to 5D schematically show structural diagrams of the workbench system in different working states according to an embodiment of the disclosure.

As shown in fig. 5A-5D, the table system includes the table 100 as previously described, and a conveyor line 200, according to an embodiment of the present disclosure. Wherein the conveyor line 200 is used for conveying a first object 5, wherein the conveying surface of the conveyor line 200 is located in the first plane. The conveyor line 200 is disposed adjacent to the lift platform 30 in the work table 100. When the top plate 33 is located in the first plane, the conveying surface of the conveying line 200 is spliced with the top plate 33.

It should be noted that the upper and lower layers of the conveyor line 200 illustrated in fig. 5A to 5D are only illustrative and not restrictive. The upper layer of the conveyor line 200 is shown for conveying the first object 5 to the work table 100, and the lower layer of the conveyor line 200 may be used for storing objects and also for conveying objects outwards, which is not limited by the present disclosure. In addition, it should be noted that the present disclosure is not limited to the system structure and the transportation manner of the first object 5 after being processed by the worker on the tabletop 21 of the table 20.

The following describes a control method for controlling the table system in conjunction with fig. 6 and different operation states of the table system in fig. 5A to 5D.

FIG. 6 schematically shows a flow chart of a control method for controlling a workbench system according to an embodiment of the present disclosure

As shown in fig. 6, the control method includes cyclically performing operations S601 to S609. Here, the operation S601, the operation S602, the operation S604, the operation S607, and the operation S608 are condition determination operations, and the next operation in the loop is continued only when the condition is satisfied, and the loop remains in the current operation when the condition is not satisfied. In this way, the ordered progression of loop operations is controlled.

In operation S601, it is determined whether the upper surface of the top plate 33 (i.e., the upper end surface of the elevating platform 30) is in the first plane. The next operation S602 is performed when the top plate 33 is in the first plane, otherwise the loop stays in the current operation to continue waiting.

Then, in operation S602, in a case where the upper surface of the top plate 33 is at the first plane, it is determined whether the upper surface of the top plate 33 is empty or not based on the sensing signals (for example, sensing signals detected by the load cell 351 and the photosensor 352). If yes, executing the next operation S603; if not, it is possible to stay in the current operation, waiting for the worker to clean the upper surface of the top plate 33.

Next, in operation S603, when it is determined that no object is placed on the upper surface of the top plate 33, the conveying line 200 is controlled to convey the first object 5 to the upper surface of the top plate 33. See the process of fig. 5A-5B.

Then, in operation S604, it is determined whether it is detected that the first object 5 is stably parked on the upper surface of the top plate 33 based on the sensing signals (e.g., sensing signals detected by the load cell 351 and the photo sensor 352). If so, the next operation S605 is executed, otherwise, the operation stays in the current operation and continues to wait.

Next, in operation S605, when it is detected that the first object 5 is stably parked on the upper surface of the top plate 33, the conveying line 200 is controlled to pause the conveying. Meanwhile, in operation S606, the telescoping mechanism 32 is controlled to move the top plate 33 until the upper surface of the top plate 33 reaches the second plane. See the process of fig. 5B-5C.

Then, in operation S607, it is determined whether the upper surface of the top plate 33 is in the second plane. If so, the next operation S608 is executed, otherwise, the operation stays in the current operation to continue waiting.

Next, in operation S608, in a case where the upper surface of the top plate 33 is in the second plane, it is determined whether it is detected that the first object 5 completely leaves the upper surface of the top plate 33 according to a sensing signal (for example, a sensing signal detected by the load cell 351). If yes, the next operation S609 is executed, otherwise, the operation stays in the current operation to continue waiting. See the process of fig. 5C-5D.

Then, in operation 609, after detecting that the first object 5 completely leaves the top plate 33, the telescoping mechanism 32 is controlled to drive the top plate 33 to move until the upper surface of the top plate 33 reaches the first plane, so as to reset the lifting platform 30. See fig. 5D.

Thereafter, the control flow returns to operation S601 to perform the next cycle.
