Description
w CLAMP ASSEMBLY AND METHOD FOR OPE=RATING THE SAME
Field of the invention The present invention relates to a clamp assembly that is added to a low profile semi automatic machine, so that, once the clamp assembly is installed on the machine, it converts it to an automatic machine.
Background of the invention The way a semi automatic machine works is simple.
a- An operator places a product to be wrappE;d onto the rotary table.
b- The operator attaches the leading end of the film to the product to be wrapped.
c- He presses start on the machine and waits for the wrap cycle to be done.
d- He cuts the film web between the producir being wrapped and the film delivering device (carriage).
e- He removes the wrapped product from the table.
To wrap the next product, the operator has to repeat all these steps, which is disadvantageous for obvious reasons well known in the art, such as lack of efficiency and productivity for example.
Summary of the invention The object of the present invention is to provide a device which satisfies some of the above-mentioned needs and which is thus an improvement over the above-discussed prior art.

6 To wrap the next product, the operator simply repeats step A, F and C
only. Step B is done automatically by the clamp assembly according to the present invention as explained herein.
Basically, an operator just needs to bring a load, press start and remove the load once it is wrapped.
The process is to automatically clamp and cut the film web at the end of the wrapping cycle:
- Place a product on the rotary table (1).
- Attach the film web (17) to the product (8) (only for the first cycle).
- Press start fio wrap the product (8).
- During the last 118 of a turn:
- A roping arm (4) is brought into roping position (10).
- A conveying belt (15} inactivated to rope down (18) the film web (17).
- A trigger (7) is moved to its triggering position (22).
- A movable clamp jaw (20) is triggerE:d to open as it passes over the trigger (7).
- The roped film web (18) is caught into the clamp (3).
- As the clamp (3) is passed over they trigger (7), its movable jaw (20) closes to hold the roped film web (18).
- The roped film web (18) is simultaneously cut with the cutter (21 ) between the product (8) and the clamp (3).

7 When a new cycle is restarted, the roped filrn web (18) is already in the clamp (3) so the operator does not need to attach it to the product.
One table revolution is made to secure the film web around the product before activating the trigger (7).
The clamp (3) is triggered in order to release tlhe initial roped film web (18).
The product (8) is wrapped.
During the last 118 of a turn the roping, clamp and cut sequences are done as described herein and illustrated in the accompanying drawings.
1- Rotary table 2- Machine base 3- Clamp assembly 4- Roping arm assembly 5- Carriage 6- Machine tower 7- Trigger
