Description

Technical Field

[0001] This utility model relates to the field of safety protection for palletizing machines, and specifically to a safety protection device for palletizing machines. Background Technology

[0002] A palletizer is a device that automatically stacks bags, cartons, or other packaging materials from a conveyor into stacks according to the customer's process requirements and then transports the stacked materials.

[0003] During the operation of the finished product packaging line palletizer, after the gripping arm grabs the yarn package, it needs to complete the X-axis translation, Y-axis movement, R-axis rotation, and Z-axis lifting actions within the working range. If personnel accidentally enter the moving area during this process, collision and crushing accidents are likely to occur. In addition, palletizers are usually not equipped with pre-installed safety protection hardware (such as guardrails, safety light curtains, etc.) or a stop device linked to the moving mechanism when they leave the factory, resulting in obvious safety deficiencies.

[0004] Therefore, it is necessary to invent a safety protection device for palletizing machines. Utility Model Content

The perimeter protection component is fixedly installed around the palletizer body, and the linkage shutdown component is fixed on the perimeter protection component.

[0007] Preferably, the enclosure protection component consists of four first supports and two second supports that are vertically fixed on the ground. The four first supports are located at the corners around the palletizer body, and a first enclosure protection net is fixed between the first supports. The first enclosure protection net is located on both sides and the rear side of the palletizer body.

[0008] Preferably, the second support is located in front of the palletizer body, and a second protective net is fixed between the second support and any one of the first supports located at the front corner of the palletizer body. A door frame is hinged between the second support and another first support located at the front corner of the palletizer body, and a third protective net is fixed inside the door frame.

[0009] Preferably, the linkage stop component consists of a first power switch and a first through-beam grating. The first power switch is fixed to the top of the second bracket, and the first through-beam grating is fixed between the door frame and the second bracket. The first power switch is electrically connected to the first through-beam grating, and the first through-beam grating is electrically connected to the controller.

[0010] Preferably, the first through-beam grating includes a first emitter and a first receiver. The bottom end of the first emitter is vertically fixed to the top of the door frame, and the bottom end of the first receiver is vertically fixed to the top of the second bracket. The first emitter and the first receiver are arranged opposite to each other.

[0011] Preferably, the linkage stop component consists of a second power switch and a second through-beam grating. The second power switch is fixed to the top of the second bracket, and the second through-beam grating is fixed between the first bracket and the second bracket, which are hinged to the door frame. The second power switch is electrically connected to the second through-beam grating, and the second through-beam grating is electrically connected to the controller.

[0017] Example 1: Please refer to the appendix. Figures 1-3 The safety protection device for palletizing machines provided by this utility model includes a palletizing machine body 1 and a controller 2. The controller 2 is electrically connected to the palletizing machine body 1. It should be noted that the palletizing machine body 1 is a common automatic palletizing equipment in the prior art, which has four-axis motion functions of X / Y / R / Z and is used to grab, transport and stack materials (such as yarn bags, cartons, etc.). The controller 2 is a programmable logic controller (PLC) or an industrial computer with built-in motion control program. It is electrically connected to the servo driver, motor and sensor of the palletizing machine body 1 through a cable to realize the coordinated control of the whole machine's movement. A safety protection mechanism is fixedly installed on the side of the palletizing machine body 1. The safety protection mechanism includes a protective enclosure component, a power switch 9 and a linkage stop component. The protective enclosure component is fixedly installed around the palletizing machine body 1, and the linkage stop component is fixed on the protective enclosure component. The fencing and protection assembly consists of four first supports 3 and two second supports 4 vertically fixed to the ground. The foundation is a horizontal concrete surface with pre-embedded anchor bolts to ensure structural stability. The four first supports 3 are located at the corners of the palletizer body 1. A first fencing net 5 is fixed between the first supports 3, located on both sides and the rear of the palletizer body 1. The second supports 4 are located in front of the palletizer body 1. The second supports 4 are connected to any one of the first supports 3 located at the corner in front of the palletizer body 1. A second protective net 6 is fixed between the two. A door frame 7 is hinged between the second support 4 and another first support 3 located at the front corner of the palletizer body 1. A third protective net 8 is fixed inside the door frame 7. Specifically, under the action of the first support 3, the second support 4, the first protective net 5, the second protective net 6 and the third protective net 8, the function of adding a barrier to protect the area around the palletizer body 1 can be realized. Under the action of the door frame 7, the barrier has an entrance to facilitate personnel to enter and exit. The linkage stop assembly consists of a first power switch 91 and a first through-beam grating 10. The first power switch 91 is fixed to the top of the second bracket 4, and the first through-beam grating 10 is fixed between the door frame 7 and the second bracket 4.

The first emitter 101 and the first receiver 102 are arranged opposite to each other. Specifically, the light emitted by the first emitter 101 can be... The first receiver 102 receives the signal. If someone accidentally enters, they will block the light, causing the first through-beam light grating 10 to send a signal to the controller 2. After receiving the signal, the controller 2 controls the palletizer body 1 to stop. This realizes the function of adding through-beam light gratings at the entrance of the enclosure, which will trigger the stop if someone accidentally enters. Combined with the use of enclosure protection around the palletizer body 1, it not only blocks the risk of collision and crushing injury, but also completes the protective hardware and linkage stop function, significantly enhancing safety. Moreover, the operator can control the switch of the first through-beam light grating 10 through the first power switch 91 to manually cut off the operation of the through-beam light grating, thereby effectively preventing the accidental triggering of the stop when someone intentionally enters.

[0018] It should be noted that the preferred through-beam grating is a safety light curtain conforming to the IEC 61496-1 / -2 standard, such as the ESQC-N1620NC2-5 model. It is suitable for safety protection in automated areas, and a single pair of gratings can provide multi-face protection. The through-beam distance is more than 30 meters, and it supports line synchronization technology and has strong anti-electromagnetic interference capabilities.
