Automatic transport device for acupuncture trays

Abstract

This application relates to an automatic tray handling device. Along the direction of gravity, a first drive mechanism and a second drive mechanism are sequentially mounted on a support. Multiple first support members are spaced apart on the first drive mechanism, each supporting a corresponding tray. A pusher is connected to the second drive mechanism. When one of the trays moves to a first position and is unloaded, the first drive mechanism drives the multiple first support members to rotate, and the trays move with the movement of the first support members. When one of the trays moves to the first position and is loaded, the second drive mechanism drives the pusher to move, and the pusher pushes the loaded tray on one of the trays to move it outside the automatic tray handling device. This solution solves the problem in related technologies where the devices do not simplify the placement of trays on the seedbed, and the trays are still manually transported to the seedbed, which is time-consuming and labor-intensive, resulting in low efficiency in placing trays on the seedbed.

Description

Technical Field

[0001] This invention relates to the field of seedling technology, and in particular to an automatic tray transport device. Background Technology

[0002] The technology of seedling cultivation in greenhouses using plug trays has developed rapidly in my country. According to statistics, vegetables cultivated using the seedling transplanting method account for 60% to 70% of the total vegetable planting volume in my country. A large number of plug trays are used in the seedling process. From the time the plug trays are sown (sowing and covering with soil) to when they are placed on the seedbed, a lot of work is required for placing the trays. In addition, during the manual handling process, the plug trays need to be stacked together. Repeated stacking of the trays will damage the plug trays and also cause the substrate soil and seeds in the plug trays to be squeezed, thereby reducing the quality of subsequent seedling cultivation and affecting the subsequent vegetable yield.

[0003] To address the aforementioned issues, Chinese invention patent number 201911065701.2 provides a stackable seedling tray storage and transportation device. This device allows seedling trays to be stacked during transportation, reducing space occupancy. Upon arrival at the designated placement location, the stored seedling trays can be sorted by layer and sequentially placed into the base storage box, facilitating subsequent placement and simplifying the tray placement mechanism. However, this structure only avoids damage to the seedling trays caused by manual stacking during tray retrieval and saves time and labor. It does not simplify the placement of seedling trays onto the seedbed; the trays are still placed manually, which is time-consuming and labor-intensive, resulting in low efficiency in placing the seedling trays on the seedbed. Summary of the Invention

[0004] Based on this, an automatic tray handling device is provided to solve the problem that the devices in the related technology do not involve simplifying the placement of trays on the seedling bed, and the trays are still manually transported to the seedling bed, which is time-consuming and labor-intensive, resulting in low efficiency in placing trays on the seedling bed.

The abortion tray detector, the controller, and the first drive cylinder are all disposed on the bracket. The blocking member is connected to the first drive cylinder. The controller is electrically connected to the second drive mechanism, the first drive cylinder, and the abortion tray detector. When one of the plurality of trays moves to the first position and is under load, the abortion tray detector detects the abortion tray carried by one of the plurality of trays and transmits a first signal to the controller. The controller controls the first drive cylinder to drive the blocking member to move to engage with one of the plurality of trays at the upper limit along the direction of gravity, and controls the second drive motor to drive the second drive gear to rotate.

[0009] Preferably, in the above-mentioned automatic transport device for acupuncture trays, the automatic transport device for acupuncture trays further includes a third drive mechanism and a plurality of second support members. The third drive mechanism is disposed on the bracket. Along the direction of gravity, the plurality of second support members are spaced apart on the third drive mechanism. When one of the plurality of trays moves to the second position and is in the unloaded state, one of the plurality of trays is disengaged from the support of one of the plurality of first support members and is supported by one of the plurality of second support members. One of the plurality of trays moves as one of the plurality of second support members rotates. The first position and the second position are arranged sequentially along the direction of gravity.

The third drive motor is mounted on the bracket. The third drive gear and the third driven gear are rotatably mounted on the bracket. The third drive gear and the third driven gear are both meshed with the third chain. The third drive gear is connected to the third drive motor. The plurality of second support members are spaced apart on the third chain. When one of the plurality of trays moves to the second position and is in the unloaded state, the third drive motor can drive the third drive gear to rotate.

When one of the trays moves to a first position and is unloaded, the first drive mechanism drives the multiple first support members to rotate, and the trays move with the movement of the first support members. When one of the trays moves to the first position and is under load, the first drive mechanism stops driving the rotation of the multiple first support members, and the second drive mechanism drives the pusher to move.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Please refer to Figures 1 to 3 This application discloses an automatic transport device for acupuncture trays, including a bracket 110, a first drive mechanism 120, a plurality of first support members 130, a second drive mechanism 140, a pusher member 150, and a plurality of trays 160.

[0025] The bracket 110 provides a mounting base for the first drive mechanism 120 and the second drive mechanism 140. Specifically, along the direction of gravity, the first drive mechanism 120 and the second drive mechanism 140 are sequentially arranged on the bracket 110. A plurality of first support members 130 are spaced apart on the first drive mechanism 120, and each of the plurality of first support members 130 supports a plurality of trays 160. The pusher 150 is connected to the second drive mechanism 140. When one of the plurality of trays 160 moves to the first position and is in an unloaded state, the first drive mechanism 120 drives the plurality of first support members 130 to rotate, and the plurality of trays 160 move with the movement of the plurality of first support members 130. When one of the plurality of trays 160 moves to the first position and is in a loaded state, the first drive mechanism 120 stops driving the plurality of first support members 130 to rotate, and the second drive mechanism 140 drives the pusher 150 to move, and the pusher 150 pushes the loaded tray of one of the plurality of trays 160 to move outside the automatic tray handling device.

[0026] The automatic tray transport device is used to place trays onto the seedling bed. During the use of the automatic tray transport device, the first position refers to the designated position on the seedling bed after the device has transported the trays. When one of the multiple trays 160 moves to the first position and is unloaded, the first drive mechanism 120 drives multiple first support members 130 to rotate. The multiple trays 160 move along with the multiple first support members 130, meaning that one of the multiple trays 160 is not carrying a tray and will not stop even if it moves to the first position, thus avoiding wasted time. When one of the multiple trays 160 moves to the first position and is loaded, the first drive mechanism 120 stops driving the multiple first support members 130 to rotate, and the second drive mechanism 140 drives the pusher 150 to move. The pusher 150 pushes the loaded tray on one of the multiple trays 160 to move outside the automatic tray transport device, thereby enabling the trays to move from the first position to the seedling bed.

[0027] The automatic tray handling device disclosed in this application includes a support 110, a first drive mechanism 120, multiple first support members 130, a second drive mechanism 140, a pusher 150, and multiple trays 160. Along the direction of gravity, the first drive mechanism 120 and the second drive mechanism 140 are sequentially arranged on the support 110. The multiple first support members 130 are spaced apart on the first drive mechanism 120, and each of the multiple first support members 130 corresponds to one of the multiple trays 160. The pusher 150 is connected to the second drive mechanism 140. The multiple trays 160... When one of the pallets 160 moves to the first position and is in an unloaded state, the first drive mechanism 120 drives the multiple first support members 130 to rotate, and the multiple pallets 160 move with the multiple first support members 130; when one of the multiple pallets 160 moves to the first position and is in a loaded state, the first drive mechanism 120 stops driving the multiple first support members 130 to rotate, and the second drive mechanism 140 drives the pusher 150 to move, and the pusher 150 pushes the loaded tray of one of the multiple pallets 160 to move outside the automatic tray handling device. The above structure is achieved through the cooperation of a first drive mechanism 120 and a second drive mechanism 140. The first drive mechanism 120 drives multiple first support members 130 to rotate, enabling multiple trays 160 to move. One of the multiple trays 160 reaches a first position and is under load. The second drive mechanism 140 drives the pusher member 150 to push the seedling tray to move outside the seedling tray automatic transport device, thereby avoiding the time and effort of manual handling of seedling trays, thus realizing the automated design of seedling tray handling and improving the efficiency of placing seedling trays on the seedling bed.

[0028] To enable the first drive mechanism 120 to drive the rotation of multiple first support members 130, and for multiple trays 160 to move along with the movement of the multiple first support members 130, in one optional embodiment, the first drive mechanism 120 may include a first drive motor 121, a first drive shaft, a first transmission shaft, and a transmission belt. Specifically, the first drive motor 121 may be mounted on a bracket 110, and both the first drive shaft and the first transmission shaft may be rotatably mounted on the bracket 110. The first drive motor 121 may be connected to the first drive shaft, and both the first drive shaft and the first transmission shaft are in rolling contact with the transmission belt. The multiple first support members 130 are spaced apart on the transmission belt. When one of the multiple trays 160 moves to a first position and is in an unloaded state, the first drive motor 121 drives the first drive shaft to rotate, the transmission belt and the first transmission shaft rotate with the first drive shaft, the multiple first support members 130 rotate with the transmission belt, and the multiple trays 160 can move along with the rotation of the multiple second support members 182. The above structure has lower installation precision, thus facilitating assembly by personnel.

[0029] In another alternative embodiment, the first drive mechanism 120 may include a first drive motor 121, a first drive gear 122, a first driven gear 123, and a first chain 124. Specifically, the first drive motor 121 may be mounted on a bracket 110. The first drive gear 122 and the first driven gear 123 may both be rotatably mounted on the bracket 110. The first drive gear 122 and the first driven gear 123 may both mesh with the first chain 124. The first drive gear 122 may be connected to the first drive motor 121. A plurality of first support members 130 may be spaced apart on the first chain 124. When one of the plurality of trays 160 moves to the first position and is in an unloaded state, the first drive motor 121 drives the first drive gear 122 to rotate. The first chain 124 and the first driven gear 123 rotate with the first drive gear 122. The plurality of first support members 130 rotate with the first chain 124. The plurality of trays 160 may move with the rotation of the plurality of second support members 182. In the above structure, the first drive gear 122 and the first driven gear 123 are both meshed with the first chain 124, which makes the transmission accuracy high, so that one of the multiple pallets 160 can be accurately moved to the first position.

[0030] To enable the second drive mechanism 140 to drive the pusher 150 to move, and for the pusher 150 to move the loaded tray of one of the multiple pallets 160 outside the automatic tray handling device, in one optional embodiment, the second drive mechanism 140 can be a drive cylinder, which can be mounted on the bracket 110. The pusher 150 can be connected to the drive cylinder. When one of the multiple pallets 160 moves to the first position and is under load, the drive cylinder drives the pusher 150 to move, and the pusher 150 pushes the loaded tray of one of the multiple pallets 160 outside the automatic tray handling device. The above structure has fewer components and lower installation precision, thus facilitating rapid installation by assembly personnel.

[0031] In another alternative embodiment, the second drive mechanism 140 may include a second drive motor 141, a second drive gear 142, a second driven gear 143, and a second chain 144. Specifically, the second drive motor 141 may be mounted on the bracket 110, and both the second drive gear 142 and the second driven gear 143 may be rotatably mounted on the bracket 110. Both the second drive gear 142 and the second driven gear 143 may mesh with the second chain 144. The second drive gear 142 may be connected to the second drive motor 141, and the pusher 150 may be connected to the second chain 144. When one of the multiple trays 160 moves to the first position and is under load, the second drive motor 141 drives the second drive gear 142 to rotate, the second chain 144 and the second driven gear 143 rotate with the second drive gear 142, and the pusher 150 rotates with the second chain 144.

[0032] In this embodiment, the automatic tray transport device may further include a first drive cylinder 171, a blocking member 172, a tray detector, and a controller. Specifically, the tray detector, the controller, and the first drive cylinder 171 may all be mounted on the bracket 110. The blocking member 172 is connected to the first drive cylinder 171. The controller is electrically connected to the second drive mechanism 140, the first drive cylinder 171, and the tray detector. When one of the multiple trays 160 moves to the first position and is under load, the tray detector detects the tray carried by one of the multiple trays 160 and transmits a first signal to the controller. The controller controls the first drive cylinder 171 to drive the blocking member 172 to move to engage with one of the multiple trays 160 at the upper limit along the direction of gravity, and controls the second drive motor 141 to drive the second drive gear 142 to rotate.

[0033] The above structure can detect whether one of the multiple trays 160 is under load when it is in the first position through the tray detector. Since the controller is electrically connected to the second drive mechanism 140, the first drive cylinder 171 and the tray detector, the controller can control the first drive cylinder 171 to drive the blocking member 172 to move to engage with one of the multiple trays 160 in the upper limit along the direction of gravity according to the first signal transmitted by the tray detector, and control the second drive motor 141 to drive the second drive gear 142 to rotate. The first signal indicates that the tray detector has detected that the tray 160 is carrying a tray. Through the above detection method and mechanical limit, one of the multiple trays 160 can be stably moved to the first position, thereby ensuring that the pusher 150 can stably push the tray to move outside the tray automatic transport device, thereby further realizing the automation design of the tray automatic transport device.

[0034] In this embodiment, the automatic tray transport device may further include a third drive mechanism 181 and a plurality of second support members 182. Specifically, the third drive mechanism 181 may be disposed on the bracket 110. Along the direction of gravity, the plurality of second support members 182 may be disposed at intervals on the third drive mechanism 181. When one of the plurality of trays 160 moves to the second position and is in an unloaded state, one of the plurality of trays 160 is detached from the support of one of the plurality of first support members 130 and is supported by one of the plurality of second support members 182. One of the plurality of trays 160 moves as one of the plurality of second support members 182 rotates. The first position and the second position are disposed sequentially along the direction of gravity.

[0035] When one of the multiple trays 160 moves to the first position and is in an unloaded state, the multiple trays 160 move along with the multiple first support members 130, and the multiple trays 160 fall along the direction of gravity. In the above structure, when one of the multiple trays 160 moves to the second position and is in an unloaded state, one of the multiple trays 160 detaches from the support of the corresponding multiple first support members 130 and is supported by one of the multiple second support members 182. One of the multiple trays 160 moves with the rotation of one of the multiple second support members 182. The first position and the second position are set sequentially along the direction of gravity, so that the trays 160 that have completed the movement of the trays outside the automatic tray handling device can be uniformly processed, and the multiple trays 160 in the unloaded state can be supported by the multiple second support members 182 one by one, thus facilitating the next use.

[0036] In one alternative embodiment, the third drive mechanism 181 may include a third drive motor 181a, a third drive gear 181b, a third driven gear 181c, and a third chain 181d. Specifically, the third drive motor 181a may be mounted on the bracket 110, and both the third drive gear 181b and the third driven gear 181c may be rotatably mounted on the bracket 110. Both the third drive gear 181b and the third driven gear 181c may mesh with the third chain 181d. The third drive motor 181a is connected, and multiple second support members 182 are spaced apart on the third chain 181d. When one of the multiple trays 160 moves to the second position and is in an unloaded state, the third drive motor 181a can drive the third drive gear 181b to rotate. The third chain 181d and the third driven gear 181c rotate with the first drive gear 122, and the multiple second support members 182 can rotate with the third chain 181d. One of the multiple trays 160 moves with the rotation of the multiple second support members 182.

[0037] In this embodiment, to facilitate quick maintenance of the pallet 160 by staff, in one optional scheme, any one of the multiple pallets 160 includes a pallet body 161, a rotating rod 162, and a first spring 163. The pallet body 161 has a first groove, in which a first connecting shaft is provided. One end of the rotating rod 162 is rotatably connected to the first connecting shaft. The first end of the first spring 163 is limited to the inner wall of the first groove, and the second end of the first spring 163 is limited to the rotating rod 162. The central axis of the first end intersects the central axis of the second end. When the rotating rod 162 rotates to a first angle and the first spring 163 is in its natural state, the other end of the rotating rod 162 is limited to the first groove. Any one of the multiple rotating rods 162 is supported by one of the multiple first support members 130 corresponding to it. When the rotating rod 162 rotates to a second angle and the first spring 163 is in a deformed state, the first groove forms a clearance space, thereby facilitating the removal of the pallet 160 from the automatic pallet handling device by staff.

[0038] In this embodiment, the automatic tray transport device may further include a fourth drive mechanism 191 and a lifting member 192. Specifically, the fourth drive mechanism 191 may be mounted on the bracket 110, and the lifting member 192 may be connected to the fourth drive mechanism 191. When multiple trays 160 are all in an unloaded state and are all supported by multiple second support members 182, the fourth drive mechanism 191 drives the lifting member 192 to move along the first direction. The lifting member 192 contacts one of the multiple trays 160 and pushes the multiple trays 160 to move. The multiple trays 160 move to be supported by multiple first support members 130 one by one. The first direction is opposite to the direction of gravity.

[0039] During the movement of each pallet 160, the rotating rod 162 will contact multiple second support members 182 and multiple first support members 130 one by one. The rotating rod 162 will switch between a first angle and a second angle. The above structure drives multiple unloaded pallets 160 to move from being supported by multiple second support members 182 to being supported by multiple first support members 130 one by one through the fourth drive mechanism 191 and the lifting member 192. This avoids the time-consuming and labor-intensive process of manually moving multiple pallets 160 to the state of being supported by multiple first support members 130 one by one. This enables multiple pallets 160 to switch between being supported by multiple first support members 130 and being supported by multiple second support members 182 one by one, thereby further realizing the automated design of the automatic pallet handling device.

[0040] In this embodiment, the support 110 may include a base 111 and a guide rod 112. Specifically, along the direction of gravity, a first drive mechanism 120 and a second drive mechanism 140 may be sequentially disposed on the base 111. Any one of the plurality of trays 160 has a through hole 164, and the guide rod 112 is guided and engaged with the plurality of through holes 164. In the above structure, in order to avoid the plurality of trays 160 from shifting or misaligning during movement, the plurality of trays 160 can be stably moved along the direction of gravity or the first direction.

[0041] In this embodiment of the application, the automatic seedling tray transport device may further include multiple rollers. Specifically, the multiple rollers can be rolled on the periphery of the base 111, thereby enabling the automatic seedling tray transport device to move and facilitating the adjustment of the docking position between the automatic seedling tray transport device and the seedling bed.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
