Description

Technical Field

[0001] This application belongs to the technical field of feeding equipment, and particularly relates to a feeding device. Background Art

[0002] In some feeding devices in the related art, the trays in the conveying bins are basically taken and placed manually, which virtually reduces the feeding efficiency and increases the labor intensity of workers. Summary of the Utility Model

[0003] The purpose of the embodiments of this application is to provide a feeding device that can solve problems such as low feeding efficiency and high labor intensity caused by the manual method.

[0004] To solve the above technical problems, this application is implemented as follows:

[0005] The embodiments of this application provide a feeding device, including: a conveying mechanism, a lifting mechanism, and a first detection mechanism;

[0006] The conveying mechanism is used to convey the bin carrying the tray to a preset position;

[0007] The first detection mechanism is spaced from the conveying mechanism in a first direction, and the first detection mechanism is correspondingly arranged with the preset position for detecting the tray;

[0008] The lifting mechanism is electrically connected to the first detection mechanism. When the first detection mechanism does not detect the tray, the lifting mechanism drives the tray in the bin to move along the first direction so that the tray moves to a position where the first detection mechanism can detect it.

[0009] In the embodiments of this application, the conveying mechanism can convey the bin carrying the tray to the preset position, and the lifting mechanism can lift the tray in the first direction so that the tray reaches a preset height that the first detection mechanism can detect. Based on this setting, the feeding device can achieve automatic conveying, automatic lifting, and automatic detection of the tray to ensure that the tray can reach the preset height, thereby facilitating subsequent picking up of the tray. Compared with the method of manually carrying the tray to the preset height, the embodiments of this application use the feeding device to replace the manual carrying method, which can reduce the labor intensity of workers, ensure personnel safety, and improve the conveying efficiency.

[0028] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0029] The terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments of this application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are usually of the same category and do not limit the number of objects. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0030] The embodiments of this application will be described in detail below in conjunction with the accompanying drawings, through specific embodiments and their application scenarios.

[0031] Referring to Figures 1 to 6 , an embodiment of this application discloses a feeding device for transporting a tray 02 carrying a product so that the tray 02 can be transported to a corresponding position, thereby laying a foundation for subsequent operations. To improve the transmission efficiency, multiple trays 02 can be stacked and placed in a magazine 01, so that multiple trays 02 can be transported at one time by transporting the magazine 01, thereby improving the transmission efficiency of the product.

[0032] The disclosed feeding device includes a transmission mechanism 10, a lifting mechanism 20, and a first detection mechanism 30.

[0033] The transmission mechanism 10 is used to transport the magazine 01 carrying the tray 02 to transport the magazine 01 to a preset position M. Optionally, the preset position M can be located at a certain position on the transmission mechanism 10. In this case, the magazine 01 can be blocked during the transportation of the magazine 01 by the transmission mechanism 10 so that the magazine 01 no longer moves with the transmission mechanism 10 after reaching the preset position M, so that the magazine 01 can stay at the preset position M. Of course, the preset position M can also be located at a certain position downstream of the transmission mechanism 10. In this way, the magazine 01 can be transmitted through the output end of the transmission mechanism 10 and reach the preset position M downstream of the transmission mechanism 10.

[0034] The lifting mechanism 20 can be set at a position corresponding to the preset position M to facilitate lifting the tray 02 in the magazine 01 at the preset position M so that the tray 02 reaches a preset height for subsequent operations. Among them, multiple layers of trays 02 can be stacked in the magazine 01. In this way, under the lifting action of the lifting mechanism 20, the topmost tray 02 first reaches the preset height to facilitate subsequent operations on the topmost tray 02. Optionally, the lifting mechanism 20 can be set at the bottom of the preset position M to facilitate lifting the tray 02 in the magazine 01 at the preset position M.

[0035] The first detection mechanism 30 and the transmission mechanism 10 are arranged at intervals in the first direction, and the first detection mechanism 30 is correspondingly arranged with the preset position M, and is used to detect whether the tray 02 reaches the preset height. Optionally, the first direction may be the up-down direction or an inclined direction at a certain angle to the up-down direction, so as to facilitate the detection of the tray 02 above the preset position M by the first detection mechanism 30.

[0036] It should be noted here that the trays 02 in the magazine 01 are stacked. When taking the tray 02, it is necessary to start from the topmost tray 02. Thus, it is necessary to lift all the trays 02 in the magazine 01 through the lifting mechanism 20 to make the topmost tray 02 reach the preset height for easy picking.

[0037] To achieve automated operation, the lifting mechanism 20 can be electrically connected to the first detection mechanism 30 so that signal transmission can be carried out between the two. Based on this, when the first detection mechanism 30 does not detect the tray 02 (that is, the tray 02 does not reach the preset height), the first detection mechanism 30 sends a signal to the lifting mechanism 20 to start the lifting mechanism 20, and the lifting mechanism 20 lifts the tray 02 in the magazine 01, so that the tray 02 moves in the first direction, so as to facilitate the movement of the tray 02 to a position where the first detection mechanism 30 can detect it, that is, to make the tray 02 reach the preset height.

[0038] Based on the above settings, in the embodiment of the present application, the magazine 01 carrying the tray 02 can be transported to the preset position M through the transmission mechanism 10, and the tray 02 can be lifted in the first direction through the lifting mechanism 20 to make the tray 02 reach the preset height that can be detected by the first detection mechanism 30. Based on this setting, the automatic transmission, automatic lifting and automatic detection of the tray 02 can be realized through the feeding device to ensure that the tray 02 can reach the preset height, so as to facilitate the subsequent picking of the tray 02. Compared with the way of manually carrying the tray 02 to the preset height, the embodiment of the present application replaces the manual carrying method with the feeding device, thereby reducing the labor intensity of personnel, ensuring personnel safety and improving the transmission efficiency.

[0039] In some embodiments, the preset position M may be located on the transmission mechanism 10, and the lifting mechanism 20 is arranged on the side of the transmission mechanism 10 away from the magazine 01 and is correspondingly arranged with the preset position M, so as to facilitate the lifting of the tray 02 in the magazine 01 at the preset position M.

[0040] Among them, the lifting mechanism 20 may include a lifting end, and the lifting end is movable in the first direction to lift the tray 02 through the lifting end.

[0041] Considering that the lifting mechanism 20 needs to lift the tray 02 in the bin 01 located at the preset position M, in order to avoid the transfer mechanism 10 blocking the lifting mechanism 20, in the embodiment of the present application, the transfer mechanism 10 is provided with an avoidance space N at the preset position M, as Figure 2 shown. By setting the avoidance space N, the lifting end of the lifting mechanism 20 can pass through the transfer mechanism 10 and contact the tray 02, so as to ensure that the lifting mechanism 20 lifts the tray 02 in the bin 01 at the preset position M.

[0042] In order to avoid the bin 01 blocking the lifting mechanism 20, the bottom of the bin 01 can be provided with an avoidance hole. By setting the avoidance hole, the lifting end of the lifting mechanism 20 can pass through the bottom of the bin 01 located at the preset position M and contact the tray 02, ensuring the lifting of the tray 02.

[0043] In addition, the above avoidance space N and the avoidance hole provided in the bin 01 located at the preset position M are correspondingly arranged, and the lifting end is correspondingly arranged with the avoidance space N and the avoidance hole respectively, so as to facilitate the lifting end to pass through.

[0044] Exemplarily, the bin 01 can include a bottom plate and a surrounding frame. The bottom plate is provided with an avoidance hole, and the surrounding frame is arranged on the bottom plate to enclose a space for accommodating the tray 02.

[0045] Based on the above settings, when the transfer mechanism 10 transfers the bin 01 to the preset position M, the lifting mechanism 20 is activated. The lifting end moves along the first direction, and successively passes through the avoidance space N and the avoidance hole and then contacts the tray 02, so that the tray 02 in the bin 01 located at the preset position M can be lifted to a preset height, so that the first detection mechanism 30 can detect it.

[0046] Optionally, when there are multiple layers of trays 02 in the bin 01, the lifting end contacts the bottommost tray 02 and drives all the trays 02 to rise until the topmost tray 02 reaches the preset height and is detected by the first detection mechanism 30 and then stops rising.

[0047] Exemplarily, the lifting mechanism 20 can be a linear drive mechanism. For example, a cylinder, a hydraulic cylinder, an electric cylinder, etc. Of course, it can also be in other forms, which are not specifically limited here.

[0048] Refer to Figure 5, in some embodiments, the transmission mechanism 10 may include a first transmission component 13 and a second transmission component 14. Among them, the first transmission component 13 and the second transmission component 14 are spaced apart in the second direction and are respectively used to carry both sides of the silo 01 in the second direction, and an avoidance space N is formed between the first transmission component 13 and the second transmission component 14. The above-mentioned second direction may be the horizontal direction, which is perpendicular to the first direction. Optionally, the first direction may be the up-down direction, the second direction may be the front-back direction, and the transmission mechanism 10 may transmit the silo 01 in the left-right direction.

[0049] Based on the above settings, the silo 01 can be carried by the first transmission component 13 and the second transmission component 14, and the silo 01 can be driven to move to achieve transmission. Moreover, an avoidance space N is formed between the first transmission component 13 and the second transmission component 14, so that the transmission mechanism 10 will not block the bottom of the silo 01, facilitating the subsequent lifting of the silo 01 by the lifting mechanism 20.

[0050] Exemplarily, both the first transmission component 13 and the second transmission component 14 may include a transmission chain or a transmission belt. The two sides of the silo 01 are carried by the transmission chains or transmission belts on both sides, and the silo 01 is driven to move forward. Of course, the first transmission component 13 and the second transmission component 14 may also include transmission rollers. The two sides of the silo 01 are carried by the transmission rollers on both sides, and the silo 01 is driven to move.

[0051] Reference Figure 1 and Figure 2 , in some embodiments, the transmission mechanism 10 may include a first transmission section 11 and a second transmission section 12, and both the first transmission section 11 and the second transmission section 12 extend in the third direction, are spaced apart in the second direction, and the transmission direction of the first transmission section 11 is opposite to the transmission direction of the second transmission section 12. Among them, the first direction, the second direction, and the third direction may be perpendicular to each other pairwise. For example, the first direction may be the up-down direction, the second direction may be the front-back direction, and the third direction may be the left-right direction.

[0052] Based on the above settings, the transmission direction of the silo 01 can be changed to meet the actual transmission requirements, and the length dimension of the transmission mechanism 10 can be shortened, and to a certain extent, the layout space of the feeding device can be utilized more fully.

[0053] It should be noted here that through the first transmission section 11, the fully loaded bin 01 can be transported to the preset position M, and the tray 02 can be lifted to the preset height by the lifting mechanism 20 to facilitate the picking up of the tray 02. After the tray 02 is picked up, operations such as testing and processing can be performed. After the operations are completed, it can be sent back to the waiting bin 01 again. After the waiting bin 01 is filled with trays 02, it continues to be transported downstream. Among them, the waiting bin 01 can be located on the first transmission section 11, or on the second transmission section 12, or can exist independently of the first transmission section 11 and the second transmission section 12.

[0054] When the waiting bin 01 is located on the first transmission section 11, the waiting bin 01 can be blocked to prevent the waiting bin 01 from moving along with the first transmission section 11; when the waiting bin 01 is located on the second transmission section, the second transmission section 12 can stop working, or block the waiting bin 01 to prevent the waiting bin 01 from moving; when the waiting bin 01 is independent of the first transmission section 11 and the second transmission section 12 respectively, the first transmission section 11 and the second transmission section 12 can operate normally.

[0055] After the waiting bin 01 is fully loaded, the block can be released and the fully loaded bin 01 can continue to be transported to transfer the fully loaded bin 01 to the downstream position.

[0056] In the embodiment of the present application, each of the first transmission section 11 and the second transmission section 12 can include a first transmission component 13 and a second transmission component 14 to facilitate carrying the two sides of the bin 01 in the second direction respectively.

[0057] To change the transmission direction of the bin 01, the feeding device can further include a commutation mechanism 40, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 shown. The commutation mechanism 40 is provided at the same end of the first transmission section 11 and the second transmission section 12, and is used to receive the bin 01 transmitted by the first transmission section 11 and transmit the bin 01 to the second transmission section 12.

[0058] In some embodiments, the preset position M can be located in the end area of the first transmission section 11. In this way, through the first transmission section 11, the bin 01 carrying the tray 02 can be transported to the preset position M, so that the tray 02 can be lifted to the preset height by the lifting mechanism 20 and picked up for operations such as testing or processing. In this case, the waiting bin 01 can be located on the commutation mechanism 40. After the waiting bin 01 is loaded, the transmission direction of the bin 01 is changed by the commutation mechanism 40 and transmitted to the second transmission section 12. Optionally, the commutation mechanism 40 can transmit the bin 01 to the second transmission section 12 along the second direction.

[0059] As Figure 4 shown, the commutation mechanism 40 may include a driving component 41 and a carrier 42 for carrying the silo 01. The carrier 42 is movably disposed between the discharge end of the first transfer section 11 and the feed end of the second transfer section 12. The driving component 41 is connected to the carrier 42 and is used to drive the carrier 42 to move in the second direction. Based on this, under the driving action of the driving component 41, the silo 01 can be driven by the carrier 42 to move towards the second transfer section 12, which can not only realize the transfer of the silo 01 but also change the transfer direction of the silo 01.

[0060] Optionally, the driving component 41 may include structures such as a motor, a lead screw, and a slider. The carrier 42 may be a carrier plate. The carrier plate is connected to the slider, the slider is threadedly connected to the lead screw, and the lead screw is drivingly connected to the rotating shaft of the motor. In this way, by driving the lead screw to rotate with the motor, the lead screw drives the slider and the carrier plate to move to realize the transfer of the silo 01. Of course, the driving component 41 may also be in other forms, such as a cylinder, a hydraulic cylinder, an electric cylinder, etc., which are not specifically limited herein.

[0061] Referring Figure 1 and Figure 2 , in some embodiments, the feeding device may further include a loading mechanism 50, and the loading mechanism 50 is used to transfer the silo 01 carrying the tray 02 to the transfer mechanism 10. Among them, the loading mechanism 50 may include a loading double-speed chain 51, and the loading double-speed chain 51 is docked with the feed end of the first transfer section 11. In this way, the use of the loading double-speed chain 51 can play a role in increasing the speed of the transfer to improve the loading efficiency.

[0062] Similarly, the feeding device may further include an unloading mechanism 60, and the unloading mechanism 60 is used to receive the silo 01 carrying the tray 02 sent out by the transfer mechanism 10. Among them, the unloading mechanism 60 may include an unloading double-speed chain 61, and the unloading double-speed chain 61 is docked with the discharge end of the second transfer section 12. In this way, the use of the unloading double-speed chain 61 can play a role in increasing the speed of the transfer to improve the unloading efficiency.

[0063] Referring Figure 3 , in some embodiments, the first detection mechanism 30 may include a signal transmitter 31 and a signal receiver 32. Among them, the signal transmitter 31 and the signal receiver 32 are spaced apart in a first plane and are used to be arranged on opposite sides of the silo 01, and the signal receiver 32 is electrically connected to the lifting mechanism 20. Among them, the above-mentioned first plane may be perpendicular to the first direction. Exemplarily, the first direction may be the up-down direction, and the first plane may be a horizontal plane.

[0064] Based on this setting, a detection signal can be emitted through the signal emitter 31, and the detection signal can be received through the signal receiver 32. When the tray 02 is lifted to the position of the preset height, the tray 02 is located between the signal emitter 31 and the signal receiver 32, so that the detection signal can be blocked, and the signal receiver 32 cannot receive the detection signal. At this time, it can be determined that the tray 02 has reached the preset height. Thus, the signal receiver 32 sends a first signal to the lifting mechanism 20 to make the lifting mechanism 20 stop lifting the tray 02, so as to facilitate the subsequent picking up of the tray 02.

[0065] When the tray 02 does not reach the position of the preset height, that is, it does not reach between the signal emitter 31 and the signal receiver 32, the detection signal will not be blocked by the tray 02 but will be received by the signal receiver 32. At this time, it can be determined that the tray 02 has not reached the preset height, and the signal receiver 32 can send a second signal to the lifting mechanism 20 to make the lifting mechanism 20 continue to lift the tray 02 until the tray 02 reaches the position of the preset height.

[0066] Exemplarily, the first detection mechanism 30 can be an optoelectronic switch. Of course, it can also be in other forms, which are not specifically limited here.

[0067] Considering that the preset position M can be located on the transmission mechanism 10, in order to make the magazine 01 be transmitted to the preset position M and no longer move along with the transmission mechanism 10, the feeding device in the embodiment of the present application can further include a blocking mechanism 70, such as Figure 1 As shown, the magazine 01 at the preset position M can be blocked by the blocking mechanism 70 to prevent the magazine 01 from continuing to move.

[0068] Among them, the blocking mechanism 70 can include a blocking member. The blocking member is movably arranged at the preset position M and is used to block the magazine 01 transmitted to the preset position M to prevent the magazine 01 from continuing to move along with the transmission mechanism 10 after reaching the preset position M, and ensure that the tray 02 in the magazine 01 can be lifted by the lifting mechanism 20. Of course, the blocking member can also release the blocking of the magazine 01 so that the magazine 01 can continue to move along with the transmission mechanism 10.

[0069] Optionally, the moving mode of the blocking member can be moving, such as moving back and forth in the first direction or moving back and forth in the second direction, so as to switch between the blocking state and the unblocking state; of course, the moving mode of the blocking member can also be rotating, such as the blocking member rotating around the axis extending in the first direction or the third direction, so as to switch between the blocking state and the unblocking state.

[0070] To achieve automatic switching of the position of the blocking member, the blocking mechanism 70 may further include a driving member, which is connected to the blocking member to drive the blocking member to move into or out of a preset position M, so as to switch between the blocking state and the unblocking state.

[0071] Exemplarily, the blocking member may be structures such as a baffle, a bar, a block, etc.; the driving member may be a cylinder, a hydraulic cylinder, an electric cylinder, a motor, a motor, etc., to drive the blocking member to move, so that the blocking member can move into or out of the preset position M.

[0072] Optionally, the blocking mechanism 70 may be provided on the first transmission section 11 of the transmission mechanism 10. Of course, it may also be provided on the second transmission section 12 or other positions, which may be specifically set according to actual requirements.

[0073] Reference Figure 1 In some embodiments, the feeding device may further include a second detection mechanism 90, which is used to detect the information of the tray 02 to ensure the accuracy of the tray 02. Exemplarily, the second detection mechanism 90 may include a barcode scanner, and the information of the tray 02 can be read through the barcode scanner to confirm the accuracy of the information of the tray 02. After the information of the tray 02 is accurate, operations such as testing and processing can be performed on the tray 02.

[0074] In addition, the feeding device may further include a transfer mechanism 80, which is used to transfer the tray 02 between the magazine 01 and the second detection mechanism 90 to facilitate the transfer of the tray 02. In addition, the transfer mechanism 80 can also be used to transfer the tray 02 to the testing or processing station to facilitate the testing or processing of the tray 02.

[0075] Exemplarily, the transfer mechanism 80 may be in the form of a manipulator or the like.

[0076] In addition, the transfer mechanism 80 includes a picking end for picking up the tray 02, and a detection element such as a photoelectric sensor, a pressure sensor, etc. may be provided at the picking end to detect whether there is a tray 02 at the picking end through the detection element.

[0077] It should be noted here that the transfer mechanism 80 and the above-mentioned picking device may be the same component, or they may be different components, but both exist at the same time.

[0078] As Figure 6 shown, taking the example of pasting a code on the tray 02, the working process of the feeding device in the embodiment of the present application is as follows:

[0079] Place the magazine 01 carrying multiple layers of unlabeled trays 02 on the loading mechanism 50, and load the magazine 01 onto the transmission mechanism 10 through the loading mechanism 50;

[0080] The silo 01 is transported to the preset position M through the transport mechanism 10;

[0081] Since the first detection mechanism 30 does not detect the tray 02, a start signal is sent to the lifting mechanism 20;

[0082] The lifting mechanism 20 is started to lift the multi-layer tray 02;

[0083] After the first detection mechanism 30 detects the topmost tray 02, a stop signal is sent to the lifting mechanism 20 again;

[0084] The transfer mechanism 80 picks up the topmost tray 02 and transfers it to the second detection mechanism 90 for code scanning. After code scanning, the tray 02 is placed in the test drawer;

[0085] The transfer mechanism 80 transfers the tray 02 from the test drawer to the printer for label pasting;

[0086] After label pasting is completed, the tray 02 with label pasted is placed in the waiting silo 01 through the transfer mechanism 80;

[0087] After the waiting silo 01 is full, the transport mechanism 10 transports the silo 01 full of trays 02 with label pasted to the discharging mechanism 60;

[0088] The discharging mechanism 60 discharges the silo 01, thus completing the entire process of transportation, label pasting and testing.

[0089] In summary, the feeding device adopted in the embodiment of the present application can reduce the labor intensity of personnel, ensure the safety of personnel, and improve the transmission efficiency.

However, the present application is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive.
