The present invention pertains to a packing device, and particularly to a packing device for packing film bags.
DESCRIPTION OF RELATED ARTIn a conventional workpiece packing method, a number of film bags are manually picked up one by one and opened, and the workpieces are then manually packed in the plastic film bags. However, since the packing is carried out manually, efficiency is low, and cost is high when a large number of workpieces are to be packed.
Therefore, a need exists in the industry to overcome the aforementioned deficiencies and inadequacies.
SUMMARY OF THE INVENTIONIn an exemplary embodiment, a packing device comprises a packing apparatus for packing film bags with workpieces, a sealing apparatus for making film bags, and a driving apparatus for pulling the film and driving the sealing apparatus. The sealing apparatus comprises a pair of sealing blocks, the sealing blocks respectively comprise two pressing portions each defining a receiving hole therein, and the receiving holes respectively receive a heating pole therein to supply heat. The packing device combines processes of making film bags and packing workpieces.
Other advantages and novel features will become more apparent from the following detailed description of preferred embodiments when taken in conjunction with the accompanying drawings, in which:

A connecting portion 2326 projects from a side of the mounting portion 2322 near the join of the mounting portion 2322 and the clamp portion 2324, and the connecting portion 2326 defines a through hole 23262 therein. Two connecting portions 2346 respectively defining a through hole 23462 therein project in parallel from a side of the mounting portion 2342. In assembly, the connecting portion 2326 is received between the two connecting portions 2346, and the through hole 23262 communicates with the two through holes 23462. A pole 280 passes through the through hole 23262 and the through holes 23462 to assemble the first portion 232 and the second portion 234 together.
The clamp portion 2344 comprises a projecting portion 262 defining a through hole 2622 therein, and the clamp portion 2324 also comprises a projecting portion (not shown) having a through hole (not shown) therein. A spring 236 is fixed between the clamp portion 2324 and the clamp portion 2344 with two ends respectively latched in the through hole 2622 and the through hole of the projecting portion of the clamp portion 2324. The clamp portion 2324 further comprises a wheel 238 mounted on an end thereof far from the mounting portion 2322, and another wheel 238 is mounted on the clamp portion 2344 in the same way and opposite to the wheel 238 of the clamp portion 2324.

Before the sealing process is carried out, the film is pulled down through the packing channel 370, and into the packing portion 374. A shape of the packing portion 374 causes the film to fold into a form of a bag. An open side of the folded film is placed between the two pulling wheels 250, and the pulling wheels 250 pull the film down during the packing process.

While the packing device is being changed from the first position to the second position, the clamp portions 2324 and 2344 are pushed outward along with the rotation of the cam 240. And the first portion 232 and the second portion 234 rotate around the pole 280 reversely. Thereby, the mounting portion 2322 and the mounting portion 2344 are driven towards each other. Accordingly, the sealing block 110 fixed to the mounting portion 2322 and the sealing block 120 fixed to the mounting portion 2342 are pushed toward each other.
While the packing device is transferred from the second position to the first position, along with the rotation of the cam 240, the clamp portion 2344 and the clamp portion 2324 are pulled back by the spring 236 until the wheels 238 abut against the waist 114 again.
Along with the rotation of the cam 240, the sealing blocks 110 and 120 are opened or closed. And because the sealing blocks 110 and 120 respectively comprise two pressing portions formed vertically with each other, the open side and a traverse portion of the folded model between the sealing blocks 110 and 120 are fused by heat emanating from the heating poles 122, to form a film bag with an open upside. Because of the zigzag knife-blade 1162 received in the pressing portion 116, the traverse portion of the film that is fused is incised into a discontinuously severed state. When a film bag with an upside open is made, the workpieces are packed into the film bag along the packing channel 370 and the film. And then the two pulling wheels 250 pull the film bag down, and the open upside of the film bag is fused in a next pressing process of the sealing blocks 110 and 120.
Because the packing device of the present invention combines making the film bags and packing the workpieces together, efficiency is upgraded and cost is lowered. Because the portions between the coterminous film bags are in a discontinuously severed state, the film bags are easy to be separated manually.
While exemplary embodiments have been described above, it should be understood that they have been presented by way of example only and not by way of limitation. Thus the breadth and scope of the present invention should not be limited by the above-described exemplary embodiments, but should be defined only in accordance with the following claims and their equivalents.
