Embodiment

[0027] A lower support type manipulator weighing feedback device is used in the operation of foam products ejected by a top rod in an EPS full-automatic molding equipment. During actual use, there are a front stacking area and a rear product receiving area. When not in operation, the device stays in the waiting area (i.e., the front stacking area). The specific operation steps are as follows:

[0028] (1) When the molding equipment opens the mold, the PLC mold opening signal is transmitted to the lower support type device, and the motor 31 is started to drive the gear 32 to drive the pallet seat 2 to enter the rear set position (i.e., the rear product receiving area) below the molding equipment;

[0029] (2) When the moving template stops opening the mold, the lifting cylinder 41 raises the pallet 5 (Note: the cylinder in this application is fully extended);

[0030] (3) The fixed mold ejector rod ejects the molded foam product, and the product enters the pallet 5. The weighing instrument 6 automatically weighs the data and feeds it back to the equipment host PLC, and the PLC automatically identifies the weight of a single mold;

[0031] (4) After the pallet 5 is loaded with products, the lifting cylinder 41 drives the pallet 5 to descend to the lowest set position, and the moving mold can automatically close the mold when it receives the start signal.

[0032] (5) The motor 31 drives the gear 32 to drive the pallet seat 2 to automatically and smoothly move to the set position in the bubble picking area (i.e., the front waiting area).

[0033] (6) The bubble picking personnel can stack the products on the pallet 5 in an orderly manner or put them into other objects.

[0034] The working process of the EPS full-automatic forming equipment is the prior art and will not be elaborated here. It should be noted in particular that: when the pallet 5 receives the product, it immediately weighs it, calculates the weight data of the single-mode product and feeds it back to the PLC of the forming equipment. The PLC of the forming equipment identifies the data and makes a judgment on whether the weight of the product is overweight or below the weight. If it is effective, it immediately automatically adjusts the die gap value of the lower die feeding, can control the standard weight data of a single product within a certain range, effectively controls the production weight cost, and meets the requirements of intelligent production.

[0035] The above is the specific use of the device of the present application for the EPS full-automatic forming equipment. The device of the present application can also be used for product transfer of other equipment.

[0036] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
