Technical Field

The invention belongs to the field of packaging, and particularly relates to a preheating platform of plastic packaging equipment and a production method for preventing stacked wires from collapsing.

Background

The material stacking and wire collapsing is an abnormal phenomenon which often occurs after a plastic package technician processes equipment to give an alarm in the packaging process, and the main reason for the material stacking and wire collapsing of the preheating platform is that after the equipment gives an alarm, the technician needs to take out products from the equipment and place the products into a material box in the processing process, and then corresponding product memory on the equipment is eliminated. However, due to misoperation of personnel, if the corresponding product on the preheating platform is cleared, and the product on the preheating platform is not taken out, the device has no memory, the object is left on the preheating platform, so that the object is not matched with the memory, and the feeder grabs the product again and places the product on the preheating platform to cause the product to be overlapped and collapsed.

The memory fool-proofing of the existing preheating platform product is only the memory of the PLC for automatic operation of the equipment, the fool-proofing can not be carried out according to the actual situation, and the equipment can still be started to operate when the memory in the preheating platform equipment is not accordant with the actual memory. Therefore, when the memory of the preheating platform is inconsistent with the actual situation, secondary material stacking and wire collapsing of products are easily caused. Therefore, how to avoid the phenomenon of wire collapse of the preheating platform due to the alarm of personnel handling equipment in the production process is a technical problem to be solved at present.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The preheating platform is used for preheating a product before plastic package and releasing the internal stress of the substrate so that the product is leveled in the mold. When the equipment automatically works, the product is placed on the preheating platform by the feeder, the equipment fool-proofing system automatically generates memory, and the product is grabbed from the preheating platform by the feeder after the preheating is carried out for a set time and is placed in a press die. The memory fool-proofing of the existing preheating platform product is only the memory of the PLC for automatic operation of the equipment, the fool-proofing can not be carried out according to the actual situation, and the equipment can still be started to operate when the memory in the preheating platform equipment is not accordant with the actual memory. When the memory of the preheating platform is inconsistent with the actual situation, secondary material stacking and wire collapsing of products are easily caused.

Referring to fig. 1, the preheating platform of the plastic packaging equipment comprises a platform base 1 and a preheating plate 3 supported and installed on the base 1 through an air cylinder 2, wherein a heating module 4 is arranged on the preheating plate 3, the preheating plate 3 is matched with a product grabbed by a feeder by controlling the air cylinder 2, the product is placed on the preheating plate 3 for preheating, a foolproof system of the equipment automatically generates memory, and the product is grabbed from the preheating plate 3 by the feeder after the preset preheating time; be provided with on the platform base 1 and be used for real-time detection to preheat and have the sensor of product on the board 3, send alarm information and shut down when the sensor detects information and the automatic memory inconsistency that produces of slow-witted system is prevented to equipment. Two groups of preheating plates 3 are oppositely arranged up and down, and the two preheating plates 3 are respectively connected with the upper cylinder 2 and the lower cylinder 2.

Referring to fig. 2, the sensor of the present invention employs a light reflection detection sensor including a light emitting diode and a light receiving diode. The light emitting diode is used as a light projection part to send an optical signal to a detection object, the optical signal is received by the light receiving diode after being transmitted, transmitted and absorbed by the detection object, and a corresponding signal is generated and output through the signal amplifier and the output circuit. Because the light signal is very weak, the light reflection detection sensor is connected with the PLC through a signal amplifier, and whether a product exists or not is detected by setting a corresponding numerical value in the amplifier. The corresponding numerical value is an amplifier alarm numerical value, when a product exists, the real-time numerical value of the amplifier is larger than the alarm numerical value, and when no product exists, the real-time numerical value of the amplifier is smaller than the alarm numerical value.

The PLC is provided with the monitoring display, and monitoring personnel can know whether the detected current product is consistent with the memory automatically generated by the equipment fool-proofing system or not through the monitoring display. On one hand, when the monitoring display detects that the condition of the product is inconsistent with the automatically generated memory, the monitoring display jumps out of an alarm page and controls the preheating platform to stop; until the condition of detecting whether the product exists is consistent with the automatically generated memory, the alarm interface can not be eliminated, and the preheating platform is controlled to start. On the other hand, when the monitoring display detects that the actual product information is inconsistent with the automatically generated memory information, the monitoring display jumps out of the alarm page and controls the preheating platform to stop; until the product information is detected to be consistent with the automatically generated memory information, the alarm interface can not be eliminated, and the preheating platform is controlled to be started. Therefore, the abnormity of material stacking and thread treading caused by the fact that the material feeder puts the product into the same preheating platform for the second time is avoided.

Generally, preheating of products before plastic packaging is completed by four mechanisms, namely a feeding device, a shifter, a feeding device and a preheating platform, wherein the feeding device pushes the products out of a material box and enters the shifter, the feeding device moves to the shifter to grab the products, the products are conveyed to the upper portion of the preheating platform through a motor, and a cylinder controls the feeding device to be matched with a base of the preheating platform to place the products on the preheating platform to complete product preheating.

The production method for preventing the stacked material and the broken wire based on the preheating platform of the plastic packaging equipment comprises the following steps of:

when the equipment automatically works, the loading device places the product on the preheating platform, the equipment fool-proofing system automatically generates memory, and the loading device picks the product from the preheating platform and places the product in a press mold after the preset time of preheating;

detecting whether a product exists on the preheating plate 3 in real time through a sensor arranged on the platform base 1, and sending alarm information and stopping when the detection information of the sensor is inconsistent with the memory automatically generated by the equipment fool-proofing system; and continuously alarming until the detection information of the sensor is consistent with the memory automatically generated by the equipment fool-proof system, and then releasing the alarm and recovering the startup.

The invention carries out real-time fool-proofing on product memory by additionally arranging the product induction sensor on the preheating platform, and the equipment automatically alarms when the equipment system memory does not accord with the actual condition. And the memory of the actual product cannot be eliminated when the personnel process the alarm, so that the abnormal wire collapse caused by the fact that the personnel eliminate the memory of the equipment and forget to take the product is further prevented.

Experiments prove that the invention can prevent the abnormal occurrence of material stacking and wire collapsing of products on the preheating platform and has outstanding effect.

It will be apparent to persons skilled in the relevant art that various modifications and changes in form and detail can be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
