Description

[Detailed Description of the Invention] 4+1: The invention relates to a meat slicer used in supermarkets, large stores, etc., which has improved operability so that even an unskilled person can accurately adjust the thickness of the meat slicer.

Recently, meat slicers are increasingly being used by unskilled people at supermarkets and large stores. Furthermore, even in general specialty stores, it is often used by unskilled personnel. On the other hand, with the distribution of mostly frozen meat, technology is required to accurately cut both fresh and frozen meat.

With conventional machines, when the thickness of fresh meat and frozen meat are set to be the same, the thickness of the sliced meat will not be the same, requiring empirical adjustments and making training for non-experts difficult.

The present invention eliminates the inconvenience of adjusting the thickness based on empirical values for hard frozen meat and soft raw meat, and allows you to select the type of meat, such as frozen meat, raw meat, hard inside meat, soft meat, etc., using a push button switch. By giving a selection instruction, it is possible to slice to a desired thickness simply by inputting the thickness as a digital value, making it easy for unskilled people to use.

Generally, the thickness of a meat slicer is determined by a meat feeding mechanism consisting of an upper roller that moves by a predetermined feed lid in conjunction with the reciprocating movement of the meat box, and a lower roller or conveyor, and a meat feeding mechanism that rotates at a fixed position. This is done by the position of a contact plate placed adjacent to the rotary blade that regulates the end surface of the meat.

However, in the case of soft raw meat, feeding is mainly performed by the feed mechanism, and the plate is moved back to a position away from the end surface of the meat so that it does not come into contact with the end surface of the meat. On the other hand, in the case of frozen meat, the thickness is set by regulating the end face of the plate, and the feed amount by the meat feeding mechanism is set to be greater than the slice thickness so that the meat is sufficiently pressed onto the plate.

The present invention automates the different adjustment methods for fresh meat and frozen meat as described above, and enables even unskilled people to easily slice raw meat, frozen meat, etc. to a predetermined thickness. Mechanism's two-part roller, and lower roller,
Or, the gap between the feed gate of the conveyor and the surface of the cutting blade of the rotary blade on the surface of the plate can be adjusted independently, and furthermore, based on the feed amount of one, the other corresponds to the feed amount multiplied by a specified coefficient. In order to output the desired output, a thickness instruction setting section, a selection section for instructing the coefficient, and an arithmetic circuit are provided, and a drive section for the meat feeding mechanism and an independent driving section for driving the plate, or a meat feeding mechanism and a conversion device are provided. The drive circuit operates the plate driving unit connected through the , and simultaneously feeds the meat at the specified feed amount and the meat feeding device and the plate to the dimensions multiplied by the specified feed ilK coefficient. You can position the plate to feed the meat at a feed rate that is the specified feed rate multiplied by a coefficient, and at the same time adjust the position of the plate to the dimension corresponding to the specified feed rate.
Be sure to do the following.

With this configuration, it is possible to easily slice to a predetermined thickness by simply operating the selected position corresponding to fresh meat or frozen meat.

1 and 2 show the basic configuration of a meat slicer and at the same time explain the mechanical parts associated with a specific example of the present invention. FIG. 1 is a top view of the mechanism, and FIG. 2 is a side view of the mechanism, showing a meat box 2 provided on the mechanism 1.
is driven by a drive motor, and is moved in parallel on the rail 4 in the direction of the arrow in the figure by a crank 3 connected to the bracket box 2. When the meat box 2 comes into contact with the rotary blade 5, the meat is sliced by the rotary blade 5 mounted on the meat box 2.

The thickness of the meat to be sliced is generally determined by the dimensions at which the meat chunks 6 are pushed out by the upper roller 7 and lower conveyor 8, but the thickness α between the plate 1o and the rotary blade 5
match the thickness of the meat to be sliced, and the upper roller 7
A system in which the meat lumps 6 are pressed against the contact plate 10 by the lower conveyor 8 may also be used.

The former is suitable for slicing relatively soft raw meat, and the latter is suitable for slicing hard frozen meat. Here, the upper roller 7 and the lower conveyor 8 are intermittently and continuously driven by a stepping motor 9 or one having a four-wheel function, and the contact plate 10 is positioned by a contact plate drive unit 11 having a position control ability.

Figure 3 shows the present invention, which enables slicing of soft raw meat and hard frozen meat to the correct thickness by simply setting the thickness digitally, instead of the conventional method of manually adjusting the thickness based on experience. This is a block diagram of one example. In this example, the instruction switch section 12
to digitally instruct the # mark at the W position, and operate the selection switch 13 that sets the ratio of the position of the plate and the feed amount of the meat feeding mechanism depending on whether the meat to be sliced is soft raw meat or hard frozen meat. It has become.

The thickness of the instruction switch section 12 and the output of the selection switch 13 are multiplied by calculation I! 1: The output that is sent to the UOI approximately 5 and completely lost by the coefficient determined by the selection switch 13 to the dimension specified by the instruction switch 412 is transmitted to the plate position control side, the upper roller 7, and the lower conveyor 8 intermittently. It is output to each of continuous drives 1-11.

These outputs are sent to gate circuit 16 and gate circuit 17.
However, the gate circuit is input to the start switch 1.
8, the gate opens immediately, and the gate closes with the stop signal from the meat box drive control circuit. The start signal is delayed by the gate circuit 17 and the delay circuit p, the gate opens after the position of the plate is controlled, the meat box drive control circuit 20 is stopped, and the gate is closed by the signal.

The output of the gate circuit 16 is the position control drive circuit 21 of the plate.
is input to drive the contact plate drive unit 11 to position the contact plate. Further, the output of the gate circuit 17 is input to a gate circuit 22 having a register. Gate 1 Route 2
2 is activated by the output of a comparison circuit 24 that compares the output of a sensor 23 that generates a signal corresponding to the number of times the meat box reciprocates with the output of the instruction switch for specifying the number of pieces, and causes the meat feeding drive circuit 25 to control the meat to the specified thickness. Input the corresponding signal. In response to this input, the meat feeding drive circuit 25 intermittently drives the stepping motor 9 to properly feed the meat lump 6.

In the specific example described above, the thickness and number of sheets are instructed using a manual switch, but it is easy to use a program card instead of the manual switch. It is also possible to add the function of this program card K) @ constant switch.

In addition, if the hardness sensor or the temperature sensor of the 26ri green meat 6 shown in FIG. 3 is used, and the output thereof is used,
l! ! The foot switch can be replaced from manual to automatic.

Furthermore, it is easy to combine the method of the present invention with a manual feed mechanism to enable manual and automatic switching.
This makes it easy to use even for workers accustomed to conventional methods.

According to the present invention, by simply pressing the selection switch for frozen meat, fresh meat, etc., and specifying the slice thickness with a switch or the like or inputting it with a program card, you can select the desired slice thickness. The skill and experience of the operator is not a concern since it is possible to slice meat that is extremely thin.

In addition, when slicing frozen meat, with conventional meat slicers, if the feed amount is incorrectly set so that the meat is pressed violently against the plate, abnormal force will be applied to the feeding mechanism, causing early damage to the feeding mechanism. According to the present invention, such inconveniences are eliminated.Furthermore, the ratchet mechanism or one-way clutch that has been used in the feeding mechanism of conventional meat slicers can be omitted, which simplifies the structure and reduces noise and waterproofing. It is also useful for solving problems such as lifespan.
