Abstract
Description
Technical Field
[0001] This utility model relates to the field of palletizer fixtures, and in particular to a palletizer fixture. Background Technology
[0002] Palletizers use robotic arms to grab boxes and arrange them in a certain quantity on pallets, stacks, and the ground, enabling intelligent operation and management. They are simple, easy to master, and can greatly reduce labor and the intensity of workers' work.
[0003] Currently, the clamps commonly used in palletizing machines on the market all use two clamps to hold the sides of the cargo box, and the pallet at the bottom of the clamps lifts the cargo box, thereby moving the cargo box for transfer and stacking.
[0004] However, when the aforementioned clamps are used to hold a box placed on a flat surface, the bottom of the box is pressed against the ground, preventing the pallet from extending into the bottom of the box and thus preventing the clamps from holding the box. Utility Model Content
[0005] The purpose of this utility model is to provide a palletizer clamp that can clamp boxes placed on a flat ground.
[0006] The technical solution adopted by the palletizing machine fixture disclosed in this utility model is:
[0007] The device includes a clamping mechanism and a connecting plate. Two clamping components are slidably connected to the clamping mechanism, and a clamping area is defined between the two clamping components. Each clamping component is equipped with a pneumatic suction cup located within the clamping area. A lifting seat is slidably connected to the clamping mechanism, and a lifting cylinder is fixedly connected to the lifting seat. The output shaft of the lifting cylinder is fixedly connected to the clamping mechanism. A traveling cylinder is fixedly connected to the lifting seat. The connecting plate is slidably connected to the lifting seat, and the output shaft of the traveling cylinder is fixedly connected to the connecting plate. A fork is fixedly connected to the bottom of the connecting plate. The output shaft of the traveling cylinder drives the fork to move away from or towards the clamping area.
[0008] As a preferred embodiment, the clamping mechanism includes a clamping seat, the clamping assembly is slidably connected to the clamping seat, and two clamping cylinders are fixedly connected to the clamping seat, with the output shaft of the clamping cylinders fixedly connected to the clamping assembly.
[0009] As a preferred embodiment, the clamping assembly includes a clamping bracket, two first guide rails are fixedly connected to the bottom of the clamping seat, the clamping bracket is slidably connected to the two first guide rails, the output shaft of the clamping cylinder is fixedly connected to the clamping bracket, a clamping arm is fixedly connected to the clamping bracket, and the pneumatic suction cup is located on the clamping arm.
[0010] As a preferred embodiment, the top of the clamping seat is provided with multiple second guide rails, the outer side of the lifting seat is slidably connected to the multiple second guide rails, and the lifting seat has a through slot.
[0011] As a preferred embodiment, two optical rods are fixedly connected to the connecting plate, and the optical rods are slidably connected to the lifting seat.
[0012] As a preferred embodiment, there are two travel cylinders, and a connecting piece is sleeved on the guide rod. The connecting piece is close to the connecting plate, and the output shaft of the travel cylinder is fixedly connected to the connecting piece.
[0013] As a preferred embodiment, a partition is fixedly connected to the outer side of the lifting seat, and the partition is located between the connecting plate and the clamping area.
[0014] The beneficial effects of the palletizer fixture disclosed in this utility model are:
[0015] The external palletizer is fixedly connected to the clamping mechanism. The external palletizer moves the clamp closer to the cargo box, placing the cargo box within the clamping area. Two clamping components slide closer to each other on the clamping mechanism and clamp the cargo box. A pneumatic suction cup adsorbs the cargo box, increasing the friction of the clamping mechanism. After the external palletizer raises the clamp to a certain height, moving the cargo box away from the flat ground, the lifting cylinder pulls the lifting seat down, making the top of the fork lower than the bottom of the cargo box. The output shaft of the travel cylinder drives the fork to slide closer to the clamping area on the lifting seat, allowing the fork to slide under the cargo box. The two clamping components release the cargo box, allowing it to be placed on the fork. The two clamping components then clamp the cargo box again, thus enabling the clamp to lift goods placed on a flat ground. Furthermore, during the transfer of the cargo box by the external palletizer, the fork can support the cargo box, preventing it from slipping between the two clamping components.

[0022] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:
[0023] Please refer to Figure 1 and Figure 2 .
[0024] The present invention discloses a palletizing machine fixture, including a clamping mechanism 1 and a connecting plate 3.
[0025] The clamping mechanism 1 includes a clamping seat 11, and two first guide rails 111 are fixedly connected to the bottom of the clamping seat 11. The two first guide rails 111 are parallel to each other.
[0026] Furthermore, two clamping components are slidably connected to the clamping mechanism 1. In this embodiment, the two clamping components are preferably symmetrical to each other. The clamping components include clamping brackets 12. Two first sliders are fixedly connected to the top of the clamping brackets 12. The two first sliders are respectively close to the two sides of the clamping brackets 12. The clamping components are slidably connected to the two first guide rails 111 of the clamping seat 11 through the two first sliders of the clamping brackets 12. The two clamping brackets 12 are respectively close to the two ends of the clamping seat 11.
[0027] Furthermore, two clamping cylinders 112 are fixedly connected to the clamping base 11. The two clamping cylinders 112 are respectively close to both ends of the clamping base 11. The output shaft of the clamping cylinder 112 is fixedly connected to the clamping bracket 12 of the clamping assembly. The extension and retraction path of the output shaft of the clamping cylinder 112 is parallel to the first guide rail 111. By pulling or pushing the clamping bracket 12 on the clamping base 11 through the output shaft of the clamping cylinder 112, the two clamping brackets 12 slide closer to each other or slide further away from each other.
[0028] Furthermore, a clamping area is set between the two clamping components. A clamping arm 121 is fixedly connected to the bottom of the clamping bracket 12. In this embodiment, it is preferable that each clamping bracket 12 has two clamping arms 121, and the two clamping arms 121 are parallel to each other. The four clamping arms 121 are located outside the clamping area. A pneumatic suction cup 122 is provided on the clamping component. In this embodiment, it is preferable that each clamping component has two pneumatic suction cups 122. The pneumatic suction cup 122 is fixedly connected to the clamping arm 121 and is located in the clamping area. The pneumatic suction cup 122 can increase the friction between the clamping arm 121 and the cargo box 4.
[0029] Please refer to Figures 1-4 .
[0030] Four mounting plates are fixedly connected to the top of the clamping base 11. The four mounting plates are respectively close to the four directions of the clamping base 11. In this embodiment, the cross-section of the mounting plate is preferably right-angled, and the horizontal edge of the mounting plate is fixedly connected to the top of the clamping base 11. The top of the clamping base 11 is provided with multiple second guide rails 113. In this embodiment, there are preferably four second guide rails 113, which correspond to the four mounting plates. The second guide rails 113 are fixedly connected to the vertical edge of the mounting plate, and the second guide rails 113 are perpendicular to the top of the clamping base 11.
[0031] Furthermore, a lifting seat 2 is slidably connected to the clamping mechanism 1, and a slot 21 is passed through the lifting seat 2. Four second sliders are fixedly connected to the outside of the lifting seat 2, and the second sliders are slidably connected to the second guide rail 113. The lifting seat 2 is suspended above the clamping seat 11. A lifting cylinder 22 is fixedly connected to the top of the lifting seat 2. In this embodiment, it is preferable to have two lifting cylinders 22, which are respectively close to the two ends of the lifting seat 2. The output shaft of the lifting cylinder 22 passes through the clamping seat 11, and the output shaft of the lifting cylinder 22 is fixedly connected to the top of the clamping seat 11. The lifting seat 2 is pulled or pushed by the output shaft of the lifting cylinder 22 to slide and rise on the clamping seat 11, so that the lifting seat 2 slides closer to the clamping seat 11 or slides away from the clamping seat 11. An external palletizer passes through the slot 21 and is fixedly connected to the top of the clamping seat 11.
[0032] A travel cylinder 23 is fixedly connected to the lifting seat 2. In this embodiment, it is preferred that there are two travel cylinders 23. The two travel cylinders 23 are respectively close to the two lifting cylinders 22. The extension and retraction paths of the output shafts of the two travel cylinders 23 are parallel to each other, and the extension and retraction paths of the output shafts of the travel cylinders 23 are perpendicular to the first guide rail 111.
[0033] The connecting plate 3 is placed on one side of the lifting seat 2. The output shaft of the traveling cylinder 23 is fixedly connected to the connecting plate 3. Two light rods 31 are fixedly connected to the top of the connecting plate 3. The two light rods 31 are parallel to each other. The extension and retraction path of the output shaft of the traveling cylinder 23 is parallel to the light rods 31. Four connectors are fixedly connected to the bottom of the lifting seat 2. Two light rods 31 are slidably connected to the four connectors at the bottom of the lifting seat 2. Connecting pieces 311 are sleeved on the light rods 31. Connecting pieces 311 are fixedly connected to the light rods 31. Connecting pieces 311 are close to the connecting plate 3. The output shaft of the traveling cylinder 23 is fixedly connected to the light rods 31 of the connecting plate 3 through the connecting pieces 311. The connecting plate 3 is slid on the lifting seat 2 by the output shaft of the traveling cylinder 23, so that the connecting plate 3 slides closer to the clamping area or slides away from the clamping area.
[0034] Furthermore, a partition 32 is fixedly connected to the outer side of the lifting seat 2. The partition 32 is located between the connecting plate 3 and the clamping area. The partition 32 can prevent goods from being left on the fork seat 33.
[0035] Furthermore, a fork seat 33 is fixedly connected to the bottom of the connecting plate 3. In this embodiment, the connecting plate 3 and the fork seat 33 are preferably arranged at a right angle. The output shaft of the traveling cylinder 23 drives the fork seat 33 away from or closer to the bottom of the clamping area.
[0036] Please refer to Figures 1-6 .
[0037] When clamping the cargo box 4:
[0038] The output shaft of the traveling cylinder 23 pushes the connecting plate 3 away from the clamping area, causing the fork 33 to move away from below the clamping area. The lifting cylinder 22 pushes the lifting seat 2 to slide and rise on the clamping seat 11, making the bottom of the fork 33 higher than the clamping arm 121. The external palletizer moves the fixture closer to the cargo box 4, so that the cargo box 4 is located within the clamping area. The state where the bottom of the fork 33 is higher than the clamping arm 121 can avoid the fork 33 interfering with the clamping arm 121 clamping the cargo box 4. The two clamping cylinders 112 drive the two clamping components to clamp the cargo box 4. The pneumatic suction cup 122 adsorbs the cargo box 4. The external palletizer raises the fixture to a height higher than the thickness of the fork 33, thereby lifting the cargo box 4 from the flat ground. Cylinder 22 pulls the lifting seat 2 to slide down on the clamping seat 11, so that the top of the fork seat 33 is lower than the bottom of the cargo box 4. The output shaft of the traveling cylinder 23 pulls the connecting plate 3 closer to the clamping area, so that the fork seat 33 is located below the clamping area. The pneumatic suction cup 122 releases the cargo box 4. The two clamping cylinders 112 drive the two clamping components to release the cargo box 4. After the cargo box 4 is placed on the top of the fork seat 33, the two clamping components clamp the cargo box 4 again. The fork seat 33 can lift the cargo box 4 to prevent the cargo box 4 from slipping between the two clamping components during the transfer. The two clamping components can limit the cargo box 4 to the top of the fork seat 33 to prevent the cargo box 4 from slipping off the fork seat 33 during the transfer.
[0039] When the cargo box 4 is lowered, the pneumatic suction cup 122 adsorbs the cargo box 4, and the output shaft of the traveling cylinder 23 pushes the connecting plate 3 away from the clamping area, so that the fork seat 33 is away from the bottom of the clamping area. The lifting cylinder 22 pushes the lifting seat 2 to slide and rise on the clamping seat 11, so that the bottom of the fork seat 33 is higher than the bottom of the cargo box 4. The external palletizer moves this fixture into the unloading area. After the cargo box 4 is placed in the unloading area, the pneumatic suction cup 122 releases the cargo box 4, and the two clamping cylinders 112 drive the two clamping components to release the cargo box 4. The external palletizer drives this fixture away from the cargo box 4 to complete the unloading.
[0040] This utility model provides a palletizer clamp. An external palletizer is fixedly connected to a clamping mechanism. The external palletizer moves the clamp closer to the cargo box, placing the cargo box within the clamping area. Two clamping components slide close to each other on the clamping mechanism and clamp the cargo box. A pneumatic suction cup adsorbs the cargo box, increasing the friction of the clamping mechanism. After the external palletizer raises the clamp to a certain height, moving the cargo box away from the flat ground, a lifting cylinder pulls the lifting seat down, making the top of the fork seat lower than the bottom of the cargo box. The output shaft of the travel cylinder drives the fork seat to slide close to the clamping area on the lifting seat, allowing the fork seat to slide under the cargo box. The two clamping components release the cargo box, allowing it to be placed on the fork seat, and then the two clamping components clamp the cargo box again. This allows the clamp to lift goods placed on a flat ground. Furthermore, during the transfer of the cargo box by the external palletizer, the fork seat can support the cargo box, preventing it from slipping between the two clamping components.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
