Description

Technical Field

[0001] The invention relates to a multi-station silo feeding device and a feeding method, belonging to the technical field of automation. Background Art

[0002] With the rapid development of the automated 3C industry, multifunctional material storage devices have increasingly higher requirements for structural simplicity and functional diversity. In automated equipment, silos are a commonly used feeding device.

[0003] Due to the complexity of the structure of the feeding device, in the current industry, whether it is a front-to-back distribution silo or a left-to-right distribution silo, the commonly used silos are only equipped with two silos, one for feeding and the other for recovering empty trays. This results in one device often being able to adapt to only one product.

[0004] The feeding device of CN216661496U discloses a left feeding space, a middle discharging space and a right feeding space, as well as a movable tray lifting and transferring mechanism. Two trays are transferred back and forth by the tray taking assembly. When the tray lifting mechanism in the left feeding space lifts the tray full of materials to the left feeding station, the tray taking assembly absorbs the tray and transfers the tray to the middle discharging station under the drive of the transfer drive device. Then, the feeding device takes away the materials at the middle discharging station, and at the same time, the tray lifting mechanism in the right feeding space lifts the tray full of materials to the right feeding station, and the tray taking assembly absorbs the tray on the right feeding station. However, this feeding device can only unload materials at the middle discharging station, and can only unload one type of material at the same time. Its alternating unloading method can only ensure the automation of unloading of a single material. When two different materials need to be unloaded at the same time, they cannot be unloaded at the same time. At this time, the alternating unloading method prolongs the working time and greatly reduces the working efficiency. When three or more materials need to be unloaded at the same time to prepare for subsequent mixing, the loading device cannot solve this technical problem at all. Therefore, its application scenario is extremely single and cannot meet the actual needs of automated production.

[0005] In view of this, it is necessary to improve the existing feeding device to solve the above problems. Summary of the invention

[0006] To solve the above technical problems, the present invention provides a loading method for a multi-station silo loading device, which can ensure that materials in at least two loading silos are received simultaneously and complete the recovery of the material tray to facilitate subsequent mixing.

[0007] The technical solution of the present invention is:

[0008] A feeding method for a multi-station silo feeding device, comprising:

[0009] There are at least five silos, including a first loading silo, a second loading silo, a recovery silo, a third loading silo and a fourth loading silo, which are arranged in sequence;

[0010] An elevator, corresponding to the silos in sequence and used to transport the materials in the silos;

[0011] At least three unloading platforms are provided and are configured to slide so as to be positioned opposite to each loading bin and receive the materials transported from the loading bin;

[0012] Monitoring modules are located on opposite sides of the lifting path of the elevator, and a monitoring area is formed between the two monitoring modules, and the monitoring area is used to monitor the position of the material and send position information;

[0013] A limiting device is mounted on the unloading platform and includes a first limiting device and an activatable second limiting device located in the moving direction of the material, the material is transported by the elevator to abut against the first limiting device, and the second limiting device can be activated to clamp the material tray carrying the material between the first limiting device and the second limiting device;

[0014] A control module, electrically connected to the elevator, the unloading platform, the monitoring module and the limit device, and controlling the lifting and lowering of the elevator and the sliding of the unloading platform;

[0015] The control module is configured to:

[0016] Controlling the unloading platform to move to a position opposite to at least two loading bins;

[0017] Allowing the elevator to transport materials in the corresponding loading bin;

[0018] receiving the position information sent by the monitoring module, and controlling the lifting position of the lift according to the position information;

[0019] Activate the limiting device to fix the material tray on the corresponding unloading platform;

[0020] Control the unloading platform to unload or continue to move to at least one unloaded unloading platform to receive the material, and then unload synchronously;

[0021] Determine the amount of material on the unloading platform;

[0022] When it is determined that the material on the unloading platform is emptied, the unloading platform is allowed to move to a position relative to the recovery bin, and the material tray supporting the material is transferred to the recovery bin by the elevator. With this arrangement, when the materials stored in multiple loading bins are different, it can be ensured that at least two unloading platforms are unloading at the same time to prepare for mixing; and through the monitoring module and the limit device, it can be ensured that the elevator transfers the material tray and the material to the specified position, which is convenient for fixing the material tray and the unloading platform, thereby ensuring stability during unloading.

[0023] As a further improvement of the present invention, the unloading platform includes a first unloading platform, a second unloading platform and a third unloading platform which are arranged in sequence and connected to each other, and the control module limits the position movement of the first unloading platform between the corresponding first loading bin, the second loading bin and the recovery bin, and limits the position movement of the third unloading platform between the corresponding recovery bin, the third loading bin and the fourth loading bin.

[0024] As a further improvement of the present invention, the control module allows the first unloading platform to receive materials from the first loading bin or the second loading bin, allows the second unloading platform to receive materials from the second loading bin or the third loading bin, and allows the third unloading platform to receive materials from the third loading bin or the fourth loading bin. By dividing each unloading platform into docking loading bins, it is easy to plan different products placed in different loading bins, and it is also easier to choose when mixing materials.

[0025] As a further improvement of the present invention, the monitoring module includes a first monitoring module installed on the unloading platform and a second monitoring module installed in the loading bin, the second monitoring module is used to monitor the amount of material in the loading bin, and the first monitoring module is used to monitor the position of the material. Through the first monitoring module and the second monitoring module, the amount of material in the loading bin can be monitored at the same time to facilitate timely replenishment, and the position of the material and the tray can also be controlled, which is practical.

[0026] As a further improvement of the present invention, the upper material bin has a plurality of stacked material trays and materials placed on the corresponding material trays. The second monitoring module monitors and records the time when each group of material trays arrives at the monitoring area of ​​the second monitoring module under the action of the elevator, and sends the time information to the control module. The control module determines the quantity of material in the upper material bin based on the time information.

[0027] As a further improvement of the present invention, within a preset time, when the material tray is not detected in the monitoring area of ​​the first monitoring module, the first monitoring module sends a no-load signal to the control module. At this time, the loading bin is in a state of no material.

[0028] As a further improvement of the present invention, during the movement of multiple unloading platforms, there is always one unloading platform opposite to the recovery bin, and at this time, the limiting device on the unloading platform can be selectively in an activated or inactivated state.

[0029] As a further improvement of the present invention, a transmission component is further provided in the silo, the material tray is mounted on the transmission component, and the transmission component is electrically connected to the control module so that the control module controls the transmission component to transport the material tray into the lifting range of the elevator.

[0030] As a further improvement of the present invention, the multi-station silo loading device also includes a CCD component adapted to the unloading platform, the CCD component is electrically connected to the control module, and is configured to be able to photograph and record the material on the unloading platform multiple times, so as to transmit the information obtained from the multiple photographs and records to the control module respectively, and the control module determines whether the material on the unloading platform is emptied based on the multiple information.

[0031] The present invention also provides a multi-station silo loading device, which applies the multi-station silo loading method mentioned above.

[0032] The beneficial technical effect of the present invention is: the movement of the unloading platform and the lifting of the elevator are controlled by the control module, so that multiple unloading platforms can be positioned relative to at least two loading bins, so as to ensure that multiple unloading platforms can receive materials from at least two loading bins at the same time, in preparation for subsequent mixing. Compared with the prior art, the loading method of the multi-station silo loading device of the present invention can unload two different materials at the same time, which also shortens the working time and greatly improves the work efficiency compared with the alternating unloading method; in addition, when three or more materials need to be unloaded at the same time, the workbench can be continued to move to achieve simultaneous unloading of multiple materials, so as to prepare for subsequent mixing. Therefore, compared with the prior art, it has a larger application surface and can better cope with the increasingly rich production needs. At the same time, by judging the unloading situation of the material through the control module, it can ensure the recovery of the material tray and realize the automatic control of the whole process.

[0044] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0045] See also Figures 1 to 3 As shown, the present invention discloses a multi-station silo loading device 100, comprising a frame assembly 1, a silo 2, an elevator 3 and a discharge platform 4. The frame assembly 1 is provided with two layers to accommodate the silo 2 and the elevator 3 respectively.

[0046] The silos 2 are provided with at least five, and include a first loading silo 21, a second loading silo 22, a recovery silo 23, a third loading silo 24 and a fourth loading silo 25 arranged in sequence, and the elevators 3 are also provided with five in sequence to transport the materials in the corresponding loading silos separately. The materials in each loading silo can be the same or different. Of course, in other embodiments, the silos 2 can be increased or decreased according to actual needs, and there is no limitation on this.

[0047] The material includes a tray 26, and the tray 26 is used to carry the material. A transmission component 27 is provided in the silo 2, and the tray 26 is transmitted to a position relative to the elevator 3 by the transmission component 27, and is driven up or down by the elevator 3. Preferably, the recovery bin 23 is arranged in the middle position of the multiple upper bins to ensure that each tray 26 can be recovered into the recovery bin 23.

[0048] The unloading platform 4 is configured to slide relative to the frame assembly 1 to sequentially correspond to each silo 2 and receive the materials transported from the silo 2. The number of the unloading platforms 4 is less than the number of the silos 2. Preferably, at least three unloading platforms 4 are provided.

[0049] In this embodiment, the unloading platform 4 includes a first unloading platform 41, a second unloading platform 42 and a third unloading platform 43 which are connected to each other. The first unloading platform 41 can be slid selectively at a position corresponding to the first loading bin 21, the second loading bin 22 and the recovery bin 23; the second unloading platform 42 can be slid selectively at a position corresponding to the second loading bin 22, the recovery bin 23 and the third loading bin 24; the third unloading platform 43 can be slid selectively at a position corresponding to the recovery bin 23, the third loading bin 24 and the fourth loading bin 25. Therefore, the unloading platform 4 can at least receive materials from two loading bins at the same time to facilitate subsequent mixing. And through the movement of the unloading platform 4, materials can also be received on all three unloading platforms 4 to complete the mixing of the three materials. This undoubtedly greatly broadens the application range and improves practicality.

[0050] The unloading platform 4 is provided with a corresponding limiting device 44. When the unloading platform 4 slides to align with the first loading bin 21 or the second loading bin 22, the material tray 26 is limited by the limiting device 4 to be fixed on the unloading platform 4. When the unloading platform 4 slides to align with the recovery bin 23, the limiting device 44 cancels the limiting of the material tray 26, allowing the material tray 26 to be transported to the recovery bin 23 by the elevator 3. The setting of the limiting device 44 is more conducive to the unloading of materials and the unloading of the material tray.

[0051] Specifically, the limiting device 44 includes a first limiting device 441 and an activatable second limiting device 442 which are independent of each other. In the height direction of the multi-station silo loading device 100, the first limiting device 441 is located on the travel path of the material tray 26 and is used to limit the upper surface of the material tray 26, and the second limiting device 442 is used to limit the lower surface of the material tray 26. Therefore, by clamping the material tray 26 by the first limiting device 441 and the second limiting device 442, the material tray 26 can be stably fixed on the unloading platform 4 for easy unloading.

[0052] The unloading platform 4 is connected from top to bottom for the material tray 26 to pass through. The first limiting device 441 is a baffle that partially extends to abut against the material tray 26. The first limiting device 441 abuts against the upper surface of the material tray 26 to limit the upward movement of the material tray 26.

[0053] The second limiting device 442 includes a limiting member 4421 capable of supporting the material tray 26, and a driving device 4422 connected to the limiting member 4421, wherein the driving device 4422 is configured to drive the limiting member 4421 to move toward the axis of the unloading platform 4 to support the lower surface of the material tray 26. Preferably, the driving device 4422 is a motor or a cylinder, which can be driven to make the limiting member 4421 support or leave the lower surface of the material tray 26. The driving device 4422 is electrically connected to the control module to be driven by the control module and activated to limit the lower surface of the unloading platform 4.

[0054] In this embodiment, the first limiting device 441 is used to limit and locate the moving position of the material tray 26 in the height direction, and the limiting member 4421 cooperates with the first limiting device 441 to fix the material tray 26 on the unloading platform 4. A plurality of the first limiting devices 441 and the second limiting devices 442 are provided to fix the material tray 26 at various angles.

[0055] The multi-station silo loading device 100 is further provided with two monitoring modules 5 on opposite sides of the lifting path of the elevator 3 , and a monitoring area is formed between the two monitoring modules 5 , and the monitoring area is used to monitor the position of the material.

[0056] Specifically, the monitoring module 5 includes a first monitoring module 51 installed on the unloading platform 4 and a second monitoring module 52 installed in the loading bin, the second monitoring module 52 is used to monitor the quantity of materials in the loading bin, and the first monitoring module 51 is used to monitor the position of the materials. Preferably, two first monitoring modules 51 are provided on each unloading platform 4, and two second monitoring modules 52 are provided in each loading bin, so as to monitor the materials twice on the travel path of the elevator 3. Preferably, the second monitoring module 52 is arranged on the top of the loading bin to monitor the materials leaving the loading bin. In other embodiments, the second monitoring module 52 can also be arranged inside the loading bin, which is not limited.

[0057] In order to realize the automation of the multi-station silo loading device 100, the present invention further provides a loading method of the multi-station silo loading device 100. The multi-station silo loading device 100 is also provided with a control module, which is electrically connected to the elevator 3, the unloading platform 4, the monitoring module 5 and the limit device 44, and controls the lifting and lowering of the elevator 3 and the sliding of the unloading platform 4. The control module is configured as follows:

[0058] Control the unloading platform 4 to move to a position opposite to at least two loading bins;

[0059] Allowing the elevator 3 to transport materials in the corresponding loading bin;

[0060] Receive the position information sent by the monitoring module 5, and control the lifting position of the elevator 3 according to the position information;

[0061] Activate the limiting device 44 to fix the material tray 26 on the corresponding unloading platform 4;

[0062] Control the unloading platform 4 to unload or continue to move to at least one unloaded unloading platform 4 to receive the material, and then unload synchronously;

[0063] Determine the amount of material on the unloading platform 4;

[0064] When it is determined that the materials on the unloading platform 4 are emptied, the unloading platform 4 is allowed to move to a position opposite to the recovery bin 23 , and the material tray 26 supporting the materials is transferred to the recovery bin 23 through the elevator 3 .

[0065] During the movement of the unloading platform 4, two of the first unloading platform 41, the second unloading platform 42 and the third unloading platform 43 can receive materials in the corresponding loading bin and unload them synchronously.

[0066] Alternatively, during the movement of the unloading platform 4, the control module can selectively control the unloading platform 4 to move until all three unloading platforms 4 receive the materials in the loading bin and unload them synchronously. In other words, it can be determined according to actual needs, that is, whether two materials are mixed or three materials are mixed, how many unloading platforms 4 are loaded with materials and unloaded synchronously.

[0067] Preferably, the control module is electrically connected to the second limiting device 442, and can activate the limiting device 44 to limit the material tray 26 on the unloading platform 4. During the movement of multiple unloading platforms 4, there is always one unloading platform 4 that is opposite to the recovery bin 23, and at this time, the limiting device 44 on the unloading platform 4 can be selectively in an activated or inactivated state. Generally speaking, the first limiting device 441 is normally blocked and is not driven by the control module. The second limiting device 442 can be controlled by the control module so that the lower surface of the material tray 26 is higher than the upper surface of the second limiting device 442, and is supported by the second limiting device 442, and then clamped between the first limiting device 441 and the second limiting device 442.

[0068] Specifically, when the unloading platform 4 starts to operate, two of the three unloading platforms 4 must be able to correspond to the corresponding loading bin and carry the materials in the loading bin, and the remaining unloading platform 4 is opposite to the recovery bin 23. At this time, if only two materials need to be mixed, the two unloading platforms 4 with materials can be directly unloaded, and then moved to the recovery bin 23 to unload the material tray 26. If three materials need to be mixed, the unloading platform 4 with materials can be unloaded first, and the last unloading platform 4 without materials can be moved instead, so that all three unloading platforms 4 are equipped with materials. At this time, the limit device 44 on the unloading platform 4 opposite to the recovery bin 23 is in an activated state, and the material tray 26 cannot be unloaded. After all the materials on the three unloading platforms 4 are unloaded, the limit device 44 on the unloading platform 4 opposite to the recovery bin 23 is in an inactivated state, and the material tray 26 is unloaded into the recovery bin 23, and the other two unloading platforms 4 unload the material tray 26 in turn. Of course, when the situation such as the first loading bin 21 and the third loading bin 24 / fourth loading bin 25 cannot be loaded at one time, it is also possible to only receive the material in the first loading bin 21 when the unloading platform 4 moves for the first time, and then move to the position corresponding to the third loading bin 24 / fourth loading bin 25 to receive the material in the third loading bin 24 / fourth loading bin 25. This can be controlled according to actual needs and there is no limitation on this.

[0069] In this embodiment, the upper bin has a plurality of material trays 26 and materials placed on the corresponding material trays 26. The second monitoring module 52 monitors and records the time when each group of material trays 26 arrives at the monitoring area of ​​the second monitoring module 52 under the action of the elevator 3, and sends the time information to the control module. The control module determines the amount of material in the upper bin based on the time information.

[0070] Therefore, the upper bin contains a plurality of stacked trays 26. When a group of trays 26 is unloaded and stored in the recovery bin 23, the time for the next group of trays 26 to move to the monitoring area of ​​the second monitoring module 52 driven by the elevator 3 will be extended. Based on the multiple gradually extended time information, the control module can determine the amount of material in the upper bin at this time. Of course, the start of this time information is calculated when the control module controls the elevator 3 to start driving the trays 26 to move. In addition, through the setting of the limit device 44, the two groups of trays 26 can also be separated, and the unloading and recycling of one group of trays 26 will not affect the next group of trays 26.

[0071] The multi-station silo loading device 100 is also provided with a signal light (not shown). When the material tray 26 and the material are detected in the monitoring area of ​​the first monitoring module 51, the first monitoring module 51 sends the position signal of the material tray 26 to the control module, and the control module controls the signal light to emit light according to the position signal to indicate the normal operation of the multi-station silo loading device 100. Preferably, when the material tray 26 and the material are detected in the monitoring area of ​​the first monitoring module 51, the upper surface of the material tray 26 approaches or abuts against the first limiting device 441. At this time, the second limiting device 442 is activated by the control module to clamp the material tray 26 between the first limiting device 441 and the second limiting device 442. That is to say, in this embodiment, the physical obstruction of the first limiting device 441 on the travel path of the material tray 26 and the monitoring and control of the first monitoring module 51 are used to complete the position limitation of the material tray 26 under the action of the elevator 3, so as to further ensure that each group of material trays 26 can stay at the specified position and be fixed to the corresponding unloading platform 4.

[0072] Within the preset time, when the material tray 26 is not detected in the monitoring area of ​​the first monitoring module 51, the first monitoring module 51 sends an empty signal to the control module. At this time, the loading bin is in a state of no material, and the signal light is prohibited from emitting light. Of course, a preset time can also be set in the control module. When the control module controls the elevator 3 to run, if the position signal is not received within the preset time, it is judged that the loading bin is in a state of no material. The operator can also judge that the loading bin is in a state of no material and needs to be replenished by the fact that the signal light has not emitted light for a long time.

[0073] The transmission component 27 is electrically connected to the control module, so that the control module controls the transmission component 27 to transport the material tray 26 to the lifting range of the elevator 3.

[0074] The multi-station silo loading device 100 also includes a CCD component (not shown) adapted to the unloading platform 4, the CCD component is electrically connected to the control module, and is configured to be able to take multiple shots and record the materials on the unloading platform 4, so as to transmit the information obtained by the multiple shots and records to the control module respectively, and the control module determines whether the materials on the unloading platform 4 are emptied according to the multiple information. Of course, in other embodiments, it is also possible to determine whether the materials are emptied by weighing the material tray 26, which is not limited to this.

[0075] Therefore, please refer to Figure 4 As shown, the feeding method of the multi-station silo feeding device 100 can be summarized into the following steps:

[0076] (1) The control module controls the transmission component 27 to operate, so as to drive the material tray 26 mounted on the transmission component 27 to move to a position aligned with the elevator 3, and the material tray 26 supports materials;

[0077] (2) The control module controls the unloading platform 4 to move to the top of the corresponding loading bin to prepare to receive the material;

[0078] (3) The control module controls the elevator 3 to transport the material tray 26 together with the material to the unloading platform 4;

[0079] (4) The control module receives the position information sent by the monitoring module 5 and controls the lifting position of the lift 3 according to the position information;

[0080] (5) The control module activates the limiting device 44 to fix the material tray 26 on the unloading platform 4, and the control module can selectively unload the material or move the unloading platform 4 to at least one unloaded unloading platform 4 to receive the material, and then unload the material synchronously;

[0081] (6) The control module controls the CCD component to take multiple photos and record the unloading platform 4, and determines the unloading status of the material on the unloading platform 4 according to the recorded information sent back by the CCD component;

[0082] (7) If all the materials on the unloading platform 4 are emptied, the control module controls the unloading platform 4 to move to a position opposite to the recovery bin 23 after unloading, and transports the material tray 26 to the recovery bin 23 through the elevator 3;

[0083] (8) If the material on the unloading platform 4 has not been emptied, continue unloading.

[0084] In this embodiment, the control module limits the first unloading platform 41 from moving between the corresponding positions of the first loading bin 21, the second loading bin 22 and the recovery bin 23, and limits the third unloading platform 43 from moving between the corresponding positions of the recovery bin 23, the third loading bin 24 and the fourth loading bin 25.

[0085] The control module allows the first unloading platform 41 to receive materials from the first loading bin 21 or the second loading bin 22, allows the second unloading platform 42 to receive materials from the second loading bin 22 or the third loading bin 24, and allows the third unloading platform 43 to receive materials from the third loading bin 24 or the fourth loading bin 25. In other words, as long as any unloading platform 4 is aligned with one of the loading bins, it can receive materials from the loading bin. Of course, for actual needs, it can also be limited to receiving materials in a certain loading bin, and there is no restriction on this.

[0086] To summarize, the multi-station silo loading device 100 and loading method of the present invention control the movement of the unloading platform 4 and the lifting and lowering of the elevator 3 through the control module, so that multiple unloading platforms 4 can be positioned relative to at least two loading silos, to ensure that multiple unloading platforms 4 can simultaneously receive materials from at least two loading silos, to prepare for subsequent mixing. At the same time, the control module is used to judge the unloading situation of the material to complete the recovery of the material tray 26.

[0087] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
