These filling machines are devices for producing wieners and the like that mainly use casings called natural intestines such as sheep intestine and pig intestine, and are composed of a cylinder and a piston for filling the casing with a fixed amount of meat or the like. There is a fixed quantity room.

From the shape of the valve that operates in cooperation with the metering chamber piston,
Two main types are used: a filling machine using the valve rotor 72 shown in FIG. 5 and a filling machine using the spool valves 74 and 75 shown in FIG.

Next, the operation of the apparatus shown in FIGS. 5 to 7 will be described.

The gear 60 is attached to the shaft 61, and meshes with the gear 62 attached to the packing 63 to rotate the packing 63 and twist the wiener sausage 66.

The gear 67 is attached to the shaft 61, and meshes with the gear 68 attached to the joint 69 to rotate the joint 69, and to rotate the filling nozzle 65 connected to the joint 69.

In FIG. 5, reference numeral 71 denotes a cylinder, which constitutes a piston 73 and a constant quantity chamber.

Further, 95 is a valve housing, which constitutes a valve with the valve rotor 72.

A joint 70 connects the valve housing 95 and the joint 69.

When the valve rotor 72 rotates, the piston 72 and the filling nozzle 65 are closed by the valve rotor 72, and the inlet pipe 96 and the cylinder 71 communicate with each other, the piston 73 descends and the meat etc. 97 fills the cylinder 71. Be done.

When the valve rotor 72 rotates further, the cylinder 71 and the filling nozzle 65 communicate with each other by the valve rotor 72, and the inlet pipe 96 and the cylinder 71 are closed, the piston 73 rises and meat 97 etc. from the filling nozzle. The casing 64 is discharged and filled.

The amount determined by the stroke of the piston 73 is filled every cycle.

FIG. 7 shows a drive mechanism for the piston 73.

The rotation of the shaft 80 is controlled by the eccentric cam bush 81.
Converted to 82 up / down motion.

The vertical movement of the cam arm 82 causes the burr arm 79 to swing about the hinge block 83 as a fulcrum, and the link plate 78 and the piston rod 77 attached to the end of the burr arm 79 opposite to the end to which the cam arm 82 is attached. The piston 73 moves up and down through.

The stroke of the piston 73 changes depending on the position of the hinge block 83 serving as the fulcrum of the burr arm 79.

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

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

The rotation of the square screw 85 moves the square screw bush 84 to the left and right, and the position of the hinge block 83 serving as the fulcrum of the burr arm 79 is set.

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.

As described above, any of the filling devices has a structure intended to fill a certain weight.

(Problems to be solved by the invention) However, the method of filling each of the objects to be packaged found in the conventional sausage filling device so as to have the same weight is due to the difference in the raw material composition and the temperature change of the heat treatment machine. There was a risk that the heat treatment yield would change, resulting in all defective products.

It is well known that in the production of sausages such as wieners, no matter how constant the filling is, the heat treatment in the next step causes a variation in weight.

In particular, depending on the ratio of red meat to fat in the raw material meat of the dough, the degree of emulsification of the dough, and the heat treatment conditions, the yield changes in lot units.

Therefore, if we are obsessed with equalization of the excess filling weight, for example, a product of 10 pieces and 300 grams is almost 290-299.
It becomes gram, and there is a situation in which it is unavoidable to put 11 pieces and to increase the number of "grooves".

Computer-controlled combination weighing scales, which have come into use in recent years, combine several individual small rods to adjust the weight of the product in one bag to be constant and to minimize the "groove". Although it has a function, if the filling weight is kept constant, the excess "residual" is increased or a product with insufficient weight is generated as in the above example.

It is an object of the present invention to provide a sausage filling device for reducing "insertion" and preventing generation of an underweight product when packaging using a combination weighing machine.

(Means for Solving the Problem) In order to reduce the “insertion” when packaging using a combination weighing machine, it is the opposite of the conventional concept of reducing the weight distribution of each packaged item. In addition, we paid attention to the fact that the larger the distribution of each weight of the packaged items, the more the original function of the combination weighing machine is exhibited.

However, if the average weight of the items to be packaged is biased, it becomes difficult to obtain the desired combined weight, so the average weight was required to be adjusted to the filling weight obtained by calculating the yield backward from the ideal average product weight. .

In order to achieve the above-mentioned object, the present invention is a filling device having a feed pump and a link forming device in a feed mechanism of a filling material, wherein the feed pump, the link forming device, and the casing chuck can be individually driven. It is characterized in that a variable speed motor and a motor controller are installed, the motor controller is connected to a sequence controller, and a program of the sequence controller sets an average filling weight and periodically changes the filling weight.

First, the change amount of each motor is set to zero, and the average filling weight is set by the sequence controller.

Next, the program of each motor controller is run so as to cause the cyclic change of the filling weight.

If there is a small periodic fluctuation of the filling weight, it can be realized by only one variable speed motor performing periodic shifting operation, but in order to obtain a certain level of dispersion, it is necessary for each motor controller to move in an associated manner. There is.

For example, if only the feed of the meat feeding pump is suddenly increased in order to increase the filling weight, the casing will rupture.Therefore, the link rotation speed of the link forming device will be reduced, or the casing chuck will move faster. , Adjust casing tension.

Further, even when two or more variable speed motors among the variable speed motors attached to the meat feeding pump, the link forming device and the casing chuck are cyclically changed at the same time, as a whole, the cyclic fluctuations are centered on the average weight. It is self-evident.

As another means for achieving the object, the present invention relates to a filling device having a meat feeding pump and a link forming device in a filling material feeding mechanism, in which the meat feeding pump is connected to be driven by a constant speed motor. , The link forming device and the casing chuck are connected via a variable speed reducer so as to be driven by another constant speed motor, the variable speed reducer is connected to a sequence controller, and the average filling weight is programmed by a program of the sequence controller. Is set and the filling weight is periodically changed.

In a conventional filling machine, a meat feeding pump is driven by a constant speed motor, and a link forming device and a casing chuck are also driven by another constant speed motor. A variable speed reducer is attached to the motor to periodically change the filling weight.

Also in this case, the average filling weight is in the state where the fluctuation value is zero,
The variable speed reducer can be adjusted and set by operating the sequence controller.

As yet another means for achieving the object, the present invention has a piston and a cylinder in a feed mechanism for the filler,
In a filling device that changes the stroke of a piston according to the position of a hinge block that is a fulcrum of a burr arm, the positioning mechanism of the hinge block has a structure in which the drive of the variable speed motor is transmitted to the hinge block by a square screw and a square screw bush. Is provided with a motor controller and a sequence controller for controlling the rotation angle, and the program of the sequence controller sets the average filling weight and periodically changes the filling weight.

This type of filling machine is mainly used for filling a natural intestine casing, and the strength of the meat feeding force based on the movement of the piston mainly affects the filling weight.

Since the stroke of the piston can be changed by the position of the hinge block serving as the fulcrum of the burr arm, a variable speed motor is attached to the positioning mechanism of the hinge block, and a motor controller for controlling the rotation angle of the variable speed motor and By providing a sequence controller and periodically changing the forward and reverse rotations of the variable speed motor by a program of the sequence controller, it becomes possible to periodically change the filling weight.

Also in this case, the average filling weight is in the state where the fluctuation value is zero,
The position of the hinge block can be adjusted and set by operating the sequence controller.

(Operation) By providing a control mechanism that automatically changes the filling amount periodically, the filling weight changes with time as shown in FIG. 1, and the weight increases and decreases cyclically around the target average weight. By repeating the above, the average weight of the sausages produced can be made constant and only variations can be produced.

(Example 1) Hereinafter, the present invention will be described in detail with reference to examples shown in the drawings.

FIG. 8 is an explanatory view showing the control mechanism of the sausage filling device of the present invention, and the variable speed motors 36, 42, 46 for driving the meat feeding pump 3, the link forming device 11, and the casing chuck 10 individually. Further, the motor controllers 51, 52, 53 are installed, and the sequence controller 54 is provided so as to control the speed of each.

It is transmitted to the casing chuck 10 by the gear 50.

In the embodiment of the present invention, the variable speed motors 42 and 46 are operated at a constant speed by the program of the sequence controller 54, and only the variable speed motor 36 is operated at a variable speed. Even when the motors 36 and 46 are in constant speed operation and only the variable speed motor 42 is in variable speed operation and the speed is changed cyclically, the variable speed motors 36 and 42 are in constant speed operation and only the variable speed motor 46 is operated. Even when variable speed operation is used and the speed is changed cyclically, even if two or more variable speed motors are both set to variable speed operation and the speed is changed cyclically, the target operating state can be obtained. it can.

Which motor is used for variable speed operation and whose speed is changed cyclically can be selected depending on the type and weight of the filling material and the type of casing used.

By setting the change cycle and the change width of the speed of the motor that operates at a variable speed, the change cycle and the change width of the filling weight can be adjusted.

This allows the distribution of the filling weight to be set freely.

Further, the average filling weight can be easily confirmed and adjusted by performing constant speed operation with the amount of change in the speed of each motor set to zero.

In the embodiment of FIG. 9, the meat feeding pump 3 is a constant speed motor 55.
The link forming device 11 and the casing chuck 10 are driven by a constant speed motor 56 via a variable speed reducer 58.

By setting the forward / reverse rotation cycle and the rotation angle of the variable speed motor 57, the change cycle and the change width of the filling weight can be adjusted.

This allows the distribution of the filling weight to be set freely.

Further, by setting the amount of change in the rotation angle of the variable speed motor 57 to zero, the average filling weight can be easily confirmed and adjusted.

(Embodiment 3) Next, a different embodiment of the present invention shown in FIG. 10 will be described.

The rotation of the shaft 80 is controlled by the eccentric cam bush 81.
Converted to 82 up / down motion.

The up-and-down movement of the cam arm 82 causes the burr arm 79 to swing about the hinge block 83 as a fulcrum, and passes through the link plate 78 and the piston rod 77 attached to the end of the burr arm 79 opposite to the end to which the cam arm 82 is attached. The piston 73 moves up and down.

The stroke of the piston 73 changes depending on the position of the hinge block 83 serving as the fulcrum of the burr arm 79.

The position of the hinge block 83 is set by the variable speed motor 92.

The rotation angle of the variable speed motor 92 depends on the timing pulley 91 and the timing belt attached to the shaft of the variable speed motor 92.

Also, the weight can be adjusted by setting with the motor controller 93.

The program incorporated in the sequence controller 94 allows the variable speed motor 92 to repeat forward / reverse rotation at a set cycle and rotation angle.

By setting the forward / reverse rotation cycle and the rotation angle of the variable speed motor 92, the change cycle and the change width of the filling weight can be adjusted.

Further, by setting the amount of change in the rotation angle of the variable speed motor 92 to zero, the average filling weight can be easily confirmed and adjusted.

(Effect) According to the present invention, since the sausage filling machine is provided with the variable speed motor whose movement is changed periodically under the control of the sequence controller, only the dispersion can be expanded without changing the average weight of the filling. As a result, when a few to several tens of pieces are selected by using a combination weighing machine for packaging the product and the product is packaged in small packages, an effect of significantly reducing the excess weight "insertion" in one packaged bag is obtained.
