Description

Technical Field

[0001] This utility model relates to the field of stacking equipment technology, and in particular to a palletizer rotary mechanism. Background Technology

[0002] A palletizer is a device that automatically stacks cartons already packed in containers onto pallets or stacks (wooden or plastic) in a specific arrangement. It can stack multiple layers and then push them out for easy transport to the warehouse by forklift. Palletizers are simple to operate and manage, and are easy to master, which can greatly reduce labor and labor intensity.

[0003] In the prior art, such as Chinese Patent No. CN222410175U, a palletizer rotary mechanism includes a base and an adjustment assembly. The base has a mounting seat rotatably connected to its upper center via a bearing, and an internal mounting groove. The adjustment assembly includes an adjustment seat, mounting rods, fixing rods, and a transmission plate. The adjustment seats are slidably connected to the bottom wall of the mounting groove. Mounting rods are located at the upper ends of the adjustment seats, and fixing rods are located on the front and rear sides of the lower end of the mounting seats. A transmission plate is rotatably connected to the upper side of the outer arc surface of the mounting rods via a bearing. The end of the transmission plate furthest from the center of the base is rotatably connected to a longitudinally adjacent fixing rod via a bearing. The mechanism also includes a control switch located at the right end of the base. This palletizer rotary mechanism can replace the traditional method of rotating the palletizer via a worm gear and turbine, offering a simple structure, improved transmission efficiency, and relatively low cost.

[0004] Although the above solution has the advantages mentioned above, it replaces the traditional worm gear and turbine drive with a screw linkage mechanism to drive the palletizer to rotate. However, due to the limitations of the linkage mechanism, its rotation angle can only be within ±90°, which causes the equipment to exhibit obvious limited rotation range in actual operation, thus affecting the operational flexibility of the system to a certain extent. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology where a screw-linkage mechanism replaces the traditional worm gear and turbine drive to rotate the palletizer. However, due to the limitations of the linkage mechanism, the rotation angle can only be within ±90°, resulting in a significant limitation on the rotation range of the equipment during actual operation, which in turn affects the operational flexibility of the system to some extent.

[0010] The second lead screw is threaded with a second connecting seat, and a toothed plate is fixedly connected to the end of the second connecting seat. The toothed plate is meshed with a gear fixedly installed at the lower end of the mounting connecting seat for transmission. A reflector plate is embedded in the side wall of the second connecting seat corresponding to the photoelectric sensor.

[0011] In a preferred embodiment, a first guide sleeve is fixedly connected to the upper end of the first connecting seat, and a second guide sleeve is fixedly connected to the top end of the second connecting seat;

[0012] The mounting base is fixedly connected to guide rods at the corresponding positions of the first guide sleeve and the second guide sleeve, and the first guide sleeve and the second guide sleeve are slidably connected to the corresponding guide rods; thus, it serves to limit the movement of the first connecting seat and the second connecting seat.

[0013] In a preferred embodiment, the mounting base is provided with two sets of maintenance doors on its side, and the end face of each maintenance door is provided with a handle to facilitate maintenance and repair of the device.

[0014] In a preferred embodiment, the mounting base is provided with mounting holes at all four corners; the control frame is fixedly mounted on the mounting base by mounting bolts, providing stable fixation and support for the device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 This embodiment provides a palletizer rotary mechanism, the specific idea of ​​which is as follows:

[0027] A palletizer rotary mechanism includes a mounting base 3 and a control frame 1. The control frame 1 is equipped with a controller 2, which is preferably a programmable logic controller (PLC) or a dedicated motion controller. A connecting ring frame 17 is rotatably mounted in the middle of the mounting base 3. A mounting connector 6 for connecting the palletizer's actuator is installed in the connecting ring frame 17. The mounting connector 6 is used to dock with the palletizer to achieve the installation and fixation of the palletizer. A gear 16 is fixedly connected to the lower end of the mounting connector 6.

[0028] The mounting base 3 is rotatably connected to the first lead screw 10 and the second lead screw 11.

[0029] The mounting base 3 is also equipped with a drive motor 9 for driving the first lead screw 10 and the second lead screw 11.

[0030] A first connecting seat 14 is threaded onto the first lead screw 10, and a photoelectric sensor 21 is installed at the end of the first connecting seat 14.

[0031] The second lead screw 11 is threaded with a second connecting seat 15, and a toothed plate 19 is fixedly connected to the end of the second connecting seat 15. The toothed plate 19 meshes with the gear 16 for transmission. A reflector plate 20 is embedded in the side wall of the second connecting seat 15 corresponding to the photoelectric sensor 21. The controller 2 is electrically connected to the drive motor 9 and the photoelectric sensor 21.

[0032] The photoelectric sensor 21 is a mirror-reflective photoelectric sensor, and the light beam emitted by it can be reflected back to the receiving end by the reflector plate 20;

[0033] The rotation of the second lead screw 11 can drive the second connecting seat 15 to move along the axis. During the movement of the second connecting seat 15, the toothed plate 19 can move synchronously. In conjunction with the gear 16, the connecting seat 6 can be driven to rotate, thereby realizing the rotation function.

[0034] The rotation of the first lead screw 10 drives the first connecting seat 14 to move along the axis. During the movement of the first connecting seat 13, the position of the photoelectric sensor 21 can be adjusted. For fine control, a displacement sensor can be installed in the mounting base 3 to precisely adjust the photoelectric sensor 21. During the movement of the second connecting seat 15, the reflector plate 20 will reflect the rays emitted by the photoelectric sensor 21, thereby generating a switching reversal signal.

[0035] Mounting base 3 has mounting holes 4 at all four corners; control frame 1 is fixedly mounted on mounting base 3 by mounting bolts 5;

[0036] The mounting base 3 is fixed to the foundation of the work site using anchor bolts through the mounting holes 4 at its four corners, providing stable support for the entire mechanism. The control frame 1 is fixed to one end of the mounting base 3 by mounting bolts 5, forming a sealed space inside to protect the core electrical components.

[0037] The first connecting seat 14 is fixedly connected to the upper end of the first guide sleeve 13, and the second connecting seat 15 is fixedly connected to the top end of the second guide sleeve 18;

[0038] The mounting base 3 is fixedly connected to the guide rod 12 at the corresponding positions of the first guide sleeve 13 and the second guide sleeve 18, and the first guide sleeve 13 and the second guide sleeve 18 are slidably connected to the corresponding guide rod 12.

[0039] The first guide sleeve 13 and the second guide sleeve 18, together with the guide rod 12, can guide the first connecting seat 14 and the second connecting seat 15, thereby limiting the movement of the first connecting seat 14 and the second connecting seat 15.

[0040] The slewing control logic of the controller is as follows:

[0041] The controller 2 receives the target rotation angle command; calculates the target position that the first connecting seat 14 needs to move according to the target angle; during the rotation of the first lead screw 10, it can drive the first connecting seat 14 and the photoelectric sensor 21 on it to move to the target position.

[0042] As the second lead screw 11 rotates, the second connecting seat 15 and the toothed plate 19 will move. The toothed plate 19 drives the gear 16 to rotate, which in turn drives the connecting ring frame 17 and the mounting connecting seat 6 to rotate.

[0043] When the second connecting seat 15 moves to the reflector plate 20 on it and enters the detection range of the photoelectric sensor 21, the reflected light can cause the signal of the photoelectric sensor 21 to change, thereby sending a trigger signal to the controller 2 through the photoelectric sensor 21.

[0044] After receiving the trigger signal, the controller 2 controls the second drive motor 9 to reverse and complete the rotation action.

[0045] The mounting base 3 has two sets of maintenance doors 7 on its side. Each maintenance door 7 has a handle 8 on its end face, which facilitates the adjustment and maintenance of the internal mechanism of the device.

[0046] Working principle:

[0047] In the initial state, both the first connecting seat 14 and the second connecting seat 15 are located at the initial end of the stroke, for example, at the end close to the drive motor 9;

[0048] When the palletizer needs to perform a rotation action, the operator inputs the target rotation angle through controller 2;

[0049] The controller 2 starts the drive motor 9 connected to the first lead screw 10, drives the first lead screw 10 to rotate, and drives the first connecting seat 14 and the photoelectric sensor 21 on it to move along the guide rod 12 to the calculated target position.

[0050] After the angle is set, the controller 2 starts the drive motor 9 connected to the second lead screw 11, driving the second lead screw 11 to rotate, which in turn moves the second connecting seat 15 and the gear plate 19 away from the motor. The linear motion of the gear plate 19 drives the gear 16 meshing with it to rotate, and the gear 16 starts to rotate through the mounting connecting seat 6;

[0051] When the second connecting seat 15 moves to the reflector plate 20 on it and enters the detection range of the photoelectric sensor 21 that has been positioned, the light beam emitted by the photoelectric sensor 21 is reflected and received by the reflector plate 20, and the sensor then generates a high-level trigger signal and sends it to the controller 2.

[0052] Upon receiving this trigger signal, the controller 2 immediately commands the second drive motor 9 to reverse, causing the second connecting seat 15 and the toothed plate 19 to move in the opposite direction back to the initial position, thus achieving the function of rotation.
