The position of the hinge block 83 is set by a weight adjustment handle 88.

The rotation angle of the weight adjustment handle 88 is determined by the rotation of the square screw 85 through a gear 87 attached to the shaft of the weight adjustment handle 88 and a gear 86 attached to the shaft of the square screw 85 that meshes with the gear 87.

As the square screw 85 rotates, the square screw bushing 84 moves left and right, and the hinge block 83 becomes the fulcrum of the Paris arm 79.

Since the filling weight is set by the stroke of the piston 73, the weight can be adjusted by manually setting the rotation angle of the weight adjustment handle 88.

(Problem U to be Solved by the Invention> However, the method of filling each packaged item to have the same weight, which is found in conventional sausage filling equipment, is difficult due to weight distribution due to differences in yield after heating. However, when packaging using a combination weighing device, the result was that the "filling", which is an excessive amount, was increased or the product was underweight.

SUMMARY OF THE INVENTION An object of the present invention is to provide a sausage filling device that reduces the amount of filling j and prevents products from being underweight when packaging using a combination weigher.

(Means for solving the problem) When packaging using a combination weighing device, in order to reduce the "filling", it is necessary to reduce the weight distribution of each packaged item, which is the conventional concept. In addition, we focused on the fact that the original function of the combination weighing device can be achieved by widening the distribution of each weight of the packaged items.

However, if the average weight of the packaged items fluctuates, the "filling" increases, so it was required to control the filling TjLx so as to widen only the distribution without changing the average weight.

In order to achieve the above object, the present invention provides: (1) In a filling device having a meat feeding pump and a link forming device in a filling material feeding mechanism, the rotation speed of the meat feeding pump is made variable, and the filling amount is periodically automatically adjusted.

(4) In a filling device having a piston and a cylinder in the feeding mechanism of the filling material, the stroke of the piston is variable and the filling amount is automatically changed periodically. It is characterized by

(Function) By providing a control AM mechanism that automatically changes the filling amount periodically, the filling weight changes over time as shown in Figure 1, and the weight increases or decreases around the target average weight. By repeating the process periodically, only the variation can be adjusted without changing the average weight of the sausages produced.
