Description

Technical Field

[0001] The utility model belongs to the technical field of safety protection of palletizing workstations, and particularly relates to a safety protection device for a palletizing workstation. Background Art

[0002] A robotic palletizing workstation is an integrated system consisting of a palletizing robot, controller, programmer, robotic gripper, automatic pallet unloader / stacker, pallet conveying and positioning equipment, and palletizing software. It also features automatic weighing, labeling, inspection, and communication systems, and is connected to the production control system to form a complete integrated packaging production line. By replacing manual labor with robots to handle boxed products, the robotic palletizing workstation not only frees up labor but also improves production efficiency, reduces safety hazards, and lowers production costs.

[0003] Currently, robotic palletizing areas require safety fences to prevent cargo from tipping over and creating safety hazards. However, in the event of a fire in the palletizing area, these fences are ineffective in preventing the spread of the fire. Therefore, we propose a palletizing workstation safety device to address this issue. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that when a fire occurs in a stacking area, the safety guardrail cannot effectively prevent the spread of the fire.

[0005] In order to achieve the above technical objectives, the technical solutions adopted by this utility model are as follows:

[0006] A safety protection device for a palletizing workstation includes a guardrail body, a transfer sleeve fixedly installed on one side of the guardrail body, and a transfer column compatible with the transfer sleeve fixedly installed on the other side, and is characterized in that: a fire extinguishing mechanism is provided on the guardrail body, and the fire extinguishing mechanism includes a storage tube with a tube opening at one end, a fireproof cloth, a plurality of counterweights and a pushing member that can push the fireproof cloth and the counterweights out of the storage tube, the storage tube is provided at the upper end of the guardrail body, the fireproof cloth is rolled up and stored in the storage tube, a plurality of counterweights are fixedly installed on the edge of the fireproof cloth at even intervals, and the pushing member is provided at the end of the storage tube.

[0007] It is further defined that the pushing member includes a pushing disk, a fixed rod, a limiting disk and a compression spring, the end of the storage cylinder is fixedly installed with a fixed cylinder, the pushing disk is movably installed in the storage cylinder, the fixed rod is rotatably installed on the pushing disk, the fixed rod passes through the storage cylinder, the limiting disk is fixedly installed on one end of the fixed rod passing through the storage cylinder, the compression spring is fixedly installed between the limiting disk and the wall of the fixed cylinder, and the fixed cylinder is provided with a clamping member that is compatible with the limiting disk. With such a structural design, the clamping member cooperates with the limiting disk to release the compressed spring that has accumulated force, so that the counterweight block and the fireproof cloth can be pushed out of the storage cylinder through the fixed rod and the pushing disk.

[0008] It is further defined that the clamping member includes a plug-in block, a movable wedge, a return spring, and an electromagnet, wherein the plug-in block is fixedly plugged into the fixed cylinder, the plug-in block is provided with a mounting slot, the movable wedge is movably engaged in the mounting slot, the return spring is fixedly installed between the movable wedge and the mounting slot wall, the movable wedge is movably engaged with the limit plate under the elastic force of the return spring, the electromagnet is fixedly installed in the mounting slot, and the plug-in block is provided with an iron block that matches the electromagnet. This structural design is simple and easy to use.

[0009] Further defined, the fixed cylinder houses a control assembly electrically connected to the electromagnet. A lead wire is fixedly connected to the input end of the control assembly, and a temperature sensor is disposed at the end of the lead wire, electrically connected to the control assembly via the lead wire. With this structural design, the temperature sensor monitors the temperature of the palletizing area. When the temperature exceeds a set threshold, the control assembly activates the electromagnet, thereby releasing the engagement between the movable wedge and the limit plate, allowing the fireproofing sheet to be released smoothly.

[0010] The storage cylinder is further defined as having multiple spiral-shaped chutes adapted for the counterweights. The chutes are spherical, and the push plate is provided with grooves adapted for the counterweights. This structural design allows the spiral chutes to guide the counterweights, allowing them to carry the fireproof cloth to the fire point and deploy it along a predetermined trajectory, resulting in more precise firefighting.

[0011] Further defined, a fixing post is fixedly mounted on the upper end of the guardrail body, a rotating ring is rotatably mounted on the fixing post, a connecting ring is rotatably mounted on the rotating ring, and the connecting ring is sleeved on the fixing tube. This structural design facilitates adjustment of the tube opening direction of the fixing tube and the storage tube via the rotating ring and the connecting ring, making use more convenient.

[0012] The utility model adopting the above technical solution has the following advantages:

[0013] In the utility model, the guardrail body is arranged in the stacking area. When a fire occurs in the stacking area, the pushing member will push the counterweight block and the fireproof cloth out of the storage tube. The pushed-out fireproof cloth will be unfolded under the action of the counterweight block, thereby covering the fire point and extinguishing it, which can effectively prevent the spread of fire and is safer.

[0030] like Figures 1 to 6 As shown, the utility model is a safety protection device for a palletizing workstation, comprising a guardrail body 1, a transfer sleeve 2 being fixedly mounted on one side of the guardrail body 1, and a transfer column 3 adapted to the transfer sleeve 2 being fixedly mounted on the other side, a fire extinguishing mechanism 4 being provided on the guardrail body 1, the fire extinguishing mechanism 4 comprising a storage tube 41 with a tube mouth opened at one end, a fireproof cloth 42, a plurality of counterweights 43 and a pushing member capable of pushing the fireproof cloth 42 and the counterweights 43 out of the storage tube 41, the storage tube 41 being arranged at the upper end of the guardrail body 1, the fireproof cloth 42 being rolled up and stored in the storage tube 41, a plurality of counterweights 43 being fixedly mounted on the edge of the fireproof cloth 42 at even intervals, and a pushing member being arranged at the end of the storage tube 41.

[0031] The pushing member includes a pushing plate 44, a fixed rod 441, a limiting plate 442 and a compression spring 443. The end of the storage cylinder 41 is fixedly installed with a fixed cylinder 440, the pushing plate 44 is movably installed in the storage cylinder 41, the fixed rod 441 is rotatably installed on the pushing plate 44, the fixed rod 441 passes through the storage cylinder 41, the limiting plate 442 is fixedly installed on one end of the fixed rod 441 passing through the storage cylinder 41, the compression spring 443 is fixedly installed between the limiting plate 442 and the cylinder wall of the fixed cylinder 440, and the fixed cylinder 440 is provided with a clip that is compatible with the limiting plate 442.

[0032] The clamping parts include a plug-in block 5, a movable wedge block 51, a return spring 52 and an electromagnet 53. The plug-in block 5 is fixedly plugged into the fixed cylinder 440. The plug-in block 5 is provided with a mounting groove. The movable wedge block 51 is movably clamped in the mounting groove. The return spring 52 is fixedly installed between the movable wedge block 51 and the wall of the mounting groove. The movable wedge block 51 is movably clamped with the limit plate 442 under the elastic force of the return spring 52. The electromagnet 53 is fixedly installed in the mounting groove. The plug-in block 5 is provided with an iron block that is compatible with the electromagnet 53.

[0033] A control component 6 electrically connected to the electromagnet 53 is provided in the fixed cylinder 440. A lead wire 61 is fixedly connected to the input end of the control component 6.

[0034] A plurality of chutes 45 compatible with the counterweight 43 are provided in the storage tube 41. The chutes 45 are spiral-shaped. The spiral chutes 45 have a guiding effect on the counterweight 43 and the fireproof cloth 42, so that the counterweight 43 can drive the fireproof cloth 42 to the set position and unfold it, and the fire extinguishing work has been successfully completed. The counterweight 43 is spherical. The spherical counterweight 43 can reduce the friction between it and the chute 45, and the resistance is smaller during movement.

[0036] The method of using the utility model is as follows:

[0037] When in use, according to the size of the palletizing area, multiple guardrail bodies 1 are assembled so that the guardrail bodies 1 enclose the palletizing area. After the palletizing area is divided into multiple small areas, the temperature sensor 62 on each guardrail body 1 is placed in the nearest small area, and the storage tube 41 is adjusted so that the tube opening of the storage tube 41 is aligned with the direction of the temperature sensor 62. The installation of the protective device is then completed.

[0038] When a fire occurs in the stacking area, the temperature sensor 62 located near the fire point detects that the temperature exceeds the threshold value. The control component 6 will control the electromagnet 53 to operate, driving the movable wedge 51 to move downward, thereby releasing the engagement between the movable wedge 51 and the limit plate 442. The compression spring 443 recovers its deformation, driving the limit plate 442, the fixing rod 441 and the push plate 44 to move rapidly, thereby pushing the counterweight 43 and the fireproof cloth 42 out of the storage cylinder 41.

[0039] When the counterweight 43 and the fireproof cloth 42 move in the storage tube 41, the spiral slide 45 guides the counterweight 43, so that the counterweight 43 can bring the fireproof cloth 42 to the fire point and unfold it according to a predetermined trajectory, thereby covering the fire point and extinguishing it, which can effectively prevent the spread of fire and provide higher safety.

[0040] The above describes in detail the safety protection device for a palletizing workstation provided by the present invention.
