Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a raw meat feeding device for feeding raw meat of sausage, ham or other processed meat products.

Structure of the Prior Art and Problems Thereof For example, in a sausage manufacturing process, as a device for feeding the raw meat to a filling machine, an apparatus has been proposed in which the raw meat is fed by a pair of reciprocating pumps including a cylinder and a piston. Used (JP-A-60-34126
issue). In this device, each reciprocating pump is arranged in parallel,
A common hopper communicates with the cylinders of the reciprocating pumps, the raw meat is put into the hopper, and the raw meat is sequentially sucked into the reciprocating pumps alternately. Then, during the suction stroke of one reciprocating pump, the other reciprocating pump discharges the raw meat. Therefore, the raw meat can be continuously fed and supplied to the filling machine. This device can also be used in the ham manufacturing process to continuously feed the raw meat of ham.

However, this device has a problem regarding the suction process of the reciprocating pump. For example, the raw meat of sausage is pasty and relatively easy to be inhaled. Especially, when the raw meat is sucked into the reciprocating pump from the hopper, when it is sucked at a high speed, the raw meat is always smoothly sucked. Not necessarily. On the other hand, the raw meat of ham contains a lump of meat and is more difficult to inhale than the raw meat of sausage, and it is difficult to inhale it at a high speed. For this reason, the driving speed of the reciprocating pump is limited, the raw meat cannot be fed at a high speed, and the machine has a low capability.

Accordingly, the present invention is an apparatus for feeding raw meat by a pair of reciprocating pumps, and when the raw meat is sucked from the hopper into the reciprocating pump, the raw meat is always smoothed regardless of the suction speed and the meat quality of the raw meat. It is intended to be inhaled into.

According to the present invention, a pair of reciprocating pumps composed of a cylinder and a piston are arranged in parallel, a common hopper is connected to the cylinders of the reciprocating pumps, raw meat is put into the hoppers, and the raw meat is fed to each reciprocating pump. In an apparatus in which the reciprocating pump sequentially inhales alternately and the other reciprocating pump discharges the raw material meat during the suction stroke of the reciprocating pump, the reciprocating pump is arranged in a position corresponding to each reciprocating pump, and the reciprocating pump is provided with a cylinder. A pair of feed blades extending spirally toward each other and rotatably guided around the central axis, and the feed blades at positions corresponding to the reciprocating pump during the suction stroke of one reciprocating pump are rotated, and the other reciprocating pump is rotated. And a control device for rotating the feed blade at a position corresponding to the reciprocating pump during the suction stroke of It is characterized by being pushed into the cylinder.

In the raw meat feeding device configured as described above, when the raw meat is put into the hopper (4) and the switching valve (28) of the hydraulic cylinder (17) is switched by the control device (31), the pump (23) Hydraulic pressure is supplied to the hydraulic cylinder (17) through the switching valve (28) and the flow control valve (27), and the rod (18) of the hydraulic cylinder (17) is supplied.
The shutter (16) is moved forward by the
5) matches the inlet (6) of the reciprocating pumps (1A) and (1B), which opens the inlets (6) of the reciprocating pumps (1A) and (1B). When the control device (31) switches the switching valve (26) of the hydraulic cylinder (7), the hydraulic pressure of the pump (23) changes.

Also, when the raw meat is sucked into the reciprocating pumps (1A) and (1B) alternately in turn, and the raw meat is discharged by the other reciprocating pump during the suction stroke of one reciprocating pump, the raw meat is continuously fed and filled. Can be supplied to the machine. The raw material of the pipe (20) is prevented from flowing backward by the check valve (21).

In addition, in this device, each feed blade is controlled by the control device (31).
When (5A) and (5B) are controlled and raw meat is sucked into one reciprocating pump (1A), the feed blade (5A) at the position corresponding to that reciprocating pump (1A) rotates and the other reciprocating pump (1A) reciprocates. The feed blade (5B) at the position corresponding to the pump (1B) does not rotate. Therefore, in the hopper (4), there is no problem that the raw material meat is compressed and agitated by the feed blade (5B).

In this embodiment, one reciprocating pump (1A) piston (3)
When it reaches 20mm before the upper limit position, the limit switch (LS1) detects it, the hydraulic cylinder (7) of the other reciprocating pump (1B) moves forward, the piston (3) rises, and Start discharging meat.

When the limit switch (LS1) detects it, the timer
When (T1) is activated and the set time of the timer (T1) has elapsed,
The hydraulic cylinder (7) of one reciprocating pump (1A) stops, and the piston (3) stops at the upper limit position. And the piston
When (3) is stopped, the timer (T2) is activated, the hydraulic cylinder (7) of one reciprocating pump (1A) is retracted, and the piston (3)
Is lowered and when the set time of the timer (T2) has elapsed, the hydraulic cylinder (7) stops and the piston (3) stops.

The piston (3) stops at a position slightly lower than the upper limit position, and the pressure of the raw meat in the cylinder (2) of the reciprocating pump (1A) is relieved. Then, when the piston (3) stops, the hydraulic cylinder (17) moves forward, the shutter (16) moves forward, the through hole (15) of the shutter (16) is aligned with the suction port (16), and the suction port ( 6) is opened.

At this time, the raw meat remaining in the cylinder is not jetted into the hopper (4) because the pressure is relieved. When the shutter (16) is fully opened, the limit switch (LS2) detects it and the hydraulic cylinder of one reciprocating pump (1A).
(7) retracts and piston (3) descends. When the limit switch (LS2) detects it, the hydraulic motor (13) is driven and the feed blade (5A) corresponding to one reciprocating pump (1A) rotates. The raw meat is pushed down by the feed blade (5A), and is sucked into the cylinder (2) of one reciprocating pump (1A) through the through hole (15) and the suction port (6).

When the piston (3) of one reciprocating pump (1A) reaches the lower limit position, the limit switch (LS3) detects it, the hydraulic motor (13) stops, and the feed vane (5A) stops. When the limit switch (LS3) detects it, the hydraulic cylinder (17)
Is retracted, the shutter (16) is retracted, and the inlet (6) is closed by the shutter (16). When the shutter (16) closes,
The limit switch (LS4) detects it and the timer (T3)
Is activated, the hydraulic cylinder (7) of one reciprocating pump (1A) moves forward, the piston (3) rises, and the piston (3) stops when the set time of the timer (T3) has elapsed. The raw meat is compressed between the piston (3) and the shutter (16). When the piston (3) of the other reciprocating pump (1B) reaches 20mm before the upper limit position, the limit switch (LS1 ') detects it and
The hydraulic cylinder (7) of one reciprocating pump (1A) moves forward, the piston (3) rises, and the raw meat is discharged. Thereafter, the same cycle is repeated, and the raw meat is reciprocating pump (1A),
By (1B), it is sequentially inhaled and discharged, and sent to the filling machine.

In addition, in this example, the case of inhaling the raw meat of the paste-like sausage was described, but instead of this,
Even raw meat of ham containing a lump of meat can be smoothly inhaled at all times.

Not only raw meat of sausage but also raw meat of ham can be inhaled at a high speed to improve the ability of the machine.

EFFECTS OF THE INVENTION As described above, according to the present invention, in a raw meat feeding device for feeding raw meat of sausage, ham or other processed meat products by a pair of reciprocating pumps, the raw meat is sucked into a cylinder of the reciprocating pump. At this time, by pushing down the raw meat with the feed blade, it is possible to always smoothly inhale. Further, even if the raw meat of ham containing a lump of meat can be inhaled at a high speed, the ability of the machine can be improved. Further, during the suction stroke of one of the reciprocating pumps, the feed blade at the position corresponding to the reciprocating pump rotates and the feed blade at the position corresponding to the other reciprocating pump does not rotate. Absent. Therefore, the intended purpose can be achieved.
