Description

Technical Field

[0001] The utility model relates to the technical field of pallet stacking and unstacking devices, and particularly to a conveying and traveling device applicable to pallet stacking and unstacking equipment for pallets. Background Art

[0002] As an indispensable loading, unloading, storage and transportation equipment in modern logistics, pallets are widely used as horizontal platform devices for containerizing, stacking, handling and transporting various goods and products. In the field of conveyor lines, pallets are particularly widely used. Once the pallets are not properly stacked after use, the work site will become extremely messy, which not only affects work efficiency but also easily leads to safety accidents. In addition, when using pallets, it is necessary to unstack the stacked pallets. However, at present, the processes of pallet stacking and unstacking mainly rely on the operation of forklifts or manual labor, and this dependence brings inconvenience to logistics operations.

[0003] There are mainly two types of empty pallet stacking or unstacking in existing palletizers. One is to grab and place with the help of a stacking and unstacking machine. A stacking and unstacking machine is a device that arranges and stacks multiple empty pallets for automatic pallet stacking or unstacking. This device stacks the pallets neatly as required, which is convenient for storage and transportation. The other is to set up an empty pallet conveyor line and place or remove single empty pallets in sequence with the help of a forklift or manual labor.

[0004] When using a stacking and unstacking machine for pallet stacking and unstacking, the common conveying and traveling mechanism realizes the linear motion and vertical lifting functions of the conveying and traveling device through the coordinated action of a track and a lifting mechanism. The main occupied space of this device comes from the traveling mechanism and the lifting mechanism, and it has limitations and is difficult to apply in some places with limited site space. Summary of the Utility Model

[0005] Aiming at the problem that the existing traveling mechanism and lifting mechanism occupy a large space and are difficult to apply to a flat space, the utility model provides a conveying and traveling device applicable to pallet stacking and unstacking equipment to solve the application problem under the condition of limited site space.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions: A conveying and traveling device applicable to pallet stacking and unstacking equipment includes a traveling mechanism and a lifting mechanism. The lifting mechanism is arranged on the traveling mechanism and makes a linear motion horizontally. The traveling mechanism includes a ground track, a sky track and a driving component arranged vertically from bottom to top. The two ends of the ground track and the sky track in the length direction are respectively connected by a first column. The lifting mechanism includes an upper moving component slidably matched with the sky track, a lower moving component slidably matched with the ground track, and a support frame arranged between the upper moving component and the lower moving component. A lifting driving component is arranged on the support frame.

[0007] Further, the driving assembly includes idler wheels disposed at both ends in the length direction of the ground rail, a synchronous belt sleeved on the two idler wheels, and a first reduction motor drivingly connected to one of the idler wheels. The first reduction motor is mounted on the ground rail. The lower moving assembly is connected to the synchronous belt through a pressing plate and moves along the length direction of the ground rail under the action of the first reduction motor and the synchronous belt.

[0008] Further, both the upper moving assembly and the lower moving assembly include supports and traveling wheels, front limit guide wheels, and rear limit guide wheels disposed on the supports. The support frame includes two second columns parallelly connected between the two supports. The traveling wheels on the upper moving assembly and the lower moving assembly are respectively fitted to the opposite sides in the vertical direction of the overhead rail and the ground rail. The front limit guide wheels and the rear limit guide wheels on the upper moving assembly are clamped on both sides in the width direction of the overhead rail, and the front limit guide wheels and the rear limit guide wheels on the lower moving assembly are clamped on both sides in the width direction of the ground rail.

[0009] Furthermore, the traveling wheels are disposed at both ends in the length direction of the support, and at least two front limit guide wheels and rear limit guide wheels are provided along the length direction of the support.

[0010] Further, elastic pads are provided on both sides in the length direction of the support.

[0011] Further, the lifting drive assembly includes sprockets disposed on the same side of the two supports, a chain is provided between the two sprockets, a second reduction motor is provided on one of the supports, the second reduction motor is drivingly connected to the chain through the sprocket, and a mounting plate is slidably connected to the two second columns. The mounting plate is fixedly connected to one side of the chain.

[0012] Furthermore, the lifting mechanism further includes two linear guide rails parallelly connected between the upper moving assembly and the lower moving assembly. The linear guide rails are fixed to the second columns. The mounting plate is slidably connected to the linear guide rails through sliders and moves in the vertical direction under the action of the second reduction motor and the chain.

[0013] In summary, the utility model has the following beneficial effects:

[0014] (1) Through the combination of the traveling mechanism and the lifting mechanism, the lateral linear motion and the vertical lifting functions of the conveying and traveling device are realized. The lifting mechanism moves in a lateral linear motion, so that the whole device can be moved to the required position in the horizontal direction. This structural design can conveniently adjust the position of the equipment and perform pallet stacking or unstacking operations, can reduce the occupied space of the traveling mechanism and the lifting mechanism, and is still applicable in a flat space, with a wide application range and good adaptability.

[0015] (2) The distance between the overhead rail and the ground rail, as well as the adjustment of the lengths of the overhead rail and the ground rail, can increase the range of movement. At the same time, the ground rail in this structure is relatively close to the ground. According to the length of the guide rail and the setting position of the sprocket, the lifting stroke range is relatively large. In this way, the lifting mechanism can carry empty pallets on the ground or empty pallets relatively close to the ground. Brief Description of the Drawings

Figure 1 and Figure 2 , the conveying and traveling device applicable to the pallet stacking and destacking equipment includes a traveling mechanism 1 and a lifting mechanism 2, which is applicable to the pallet stacking and destacking equipment and can provide stable movement support for the conveying and positioning of pallets. The lifting mechanism 2 is arranged on the traveling mechanism 1 and moves linearly in the transverse direction. The traveling mechanism 1 includes a ground rail 11, an overhead rail 12 and a driving component arranged vertically from bottom to top. The two ends of the ground rail 11 and the overhead rail 12 in the length direction are respectively connected by a first upright column 13. The lifting mechanism 2 includes an upper moving component 21 slidably matched with the overhead rail 12, a lower moving component 22 slidably matched with the ground rail 11, and a support frame arranged between the upper moving component 21 and the lower moving component 22. A lifting driving component is arranged on the support frame. The arrangement of the ground rail 11 and the overhead rail 12 enables the device to move in the vertical direction, realizing the lifting and lowering of the pallet clamping, so as to facilitate the stacking and destacking operations.

[0022] During implementation, the driving assembly includes idler wheels 16 provided at both ends in the length direction of the ground rail 11, a synchronous belt 14 sleeved on the two idler wheels 16, and a first reduction motor 15 drivingly connected to one of the idler wheels 16. The driving mode of the idler wheels 16 and the synchronous belt 14 can provide stable driving force and reduce noise and vibration during transmission. Among them, the first reduction motor 15 is installed on the ground rail 11, and controls the lower moving assembly 22 by driving the synchronous belt 14, so as to achieve smooth movement along the length direction of the ground rail 11. The lower moving assembly 22 is connected to the synchronous belt 14 through a pressing plate, ensuring the reliability of transmission, and moves along the length direction of the ground rail 11 under the action of the first reduction motor 15 and the synchronous belt 14. The motor drives the synchronous belt 14 to operate, and the operation of the synchronous belt 14 drives the movement of the lower moving assembly 22.

[0023] The lifting mechanism 2 includes an upper moving assembly 21 slidably engaged with the overhead rail 12 and a lower moving assembly 22 slidably engaged with the ground rail 11. A driving assembly is provided between the lower moving assembly 22 and the ground rail 11.

The slidable engagement of the upper moving assembly 21 and the lower moving assembly 22 enables the device to move on a horizontal straight line, realizing the lateral movement of the tray clamping and ensuring the accurate positioning and conveying of the tray.

[0024] Embodiment 2:

[0025] As Figure 1 and Figure 2 shown, based on the conveying and traveling device applicable to the tray stacking and unstacking equipment in Embodiment 1, it includes a traveling mechanism 1 and a lifting mechanism 2.

The support frame includes two second columns 27 connected in parallel between the two supports 221. Through the connection of the second columns 27, the upper moving assembly 21 and the lower moving assembly 22 are kept parallel, further enhancing the stability and positioning accuracy of the device. The traveling wheels 222 on the upper moving assembly 21 and the lower moving assembly 22 are respectively engaged with the opposite sides in the vertical direction of the overhead rail 12 and the ground rail 11.

The lifting mechanism 2 can maintain stable traveling performance. The clamping design of the front limit guide wheels 223 and rear limit guide wheels 224 ensures the stability of the device during movement and limits the moving range, avoiding movement errors caused by deviating from the track.

[0027] Preferably, at least two running wheels 222 are provided, which are arranged at both ends in the length direction of the support 221, and at least two front limiting guide wheels 223 and rear limiting guide wheels 224 are provided along the length direction of the support 221. Increasing the contact points between the running wheels 222 and the track, and the contact points between the front limiting guide wheels 223 and the rear limiting guide wheels 224 and the track improves the stability and load-bearing capacity of the device.

[0028] Elastic pads 225 are arranged on both sides of the support 221 along the length direction. The elastic pads 225 include rubber pads, which play a role of shock absorption and buffering.

[0029] During implementation, a sprocket 226 is provided on the same side of the two supports 221, and the position of the sprocket 226 is close to the ground. A chain 24 is provided between the two sprockets 226, and a second reduction motor 23 is provided on one of the supports 221, and the second reduction motor 23 is connected to the chain 24 through the sprocket 226.

The back side of the mounting plate 26 is fixed to the left or right chain 24, and moves synchronously with the chain 24. The front side of the mounting plate 26 is used to install a mechanism for clamping an empty pallet.

[0030] During implementation, the lifting mechanism 2 also includes two linear guide rails 25 connected in parallel between the upper moving component 21 and the lower moving component 22. The linear guide rails 25 are fixed on the second column 27.
