Description

[Detailed Description of the Invention] The present invention relates to an automatically feeding band saw machine for continuously cutting frozen foods to a constant thickness.

Machines that automatically feed and cut materials containing oil, fat, and water, such as frozen meat chunks, are known, but all conventional machines of this kind have a structure in which the material is cut by rotating a round blade. Therefore, when thinly slicing material such as meat that has been hardened by freezing, the cut pieces may warp in a curved shape due to the conical flank that forms the cutting edge of a round knife or the bearing of a round knife. However, the curved and overhanging cut surface tends to cause cracks and breakage, and the straightness of the cut surface reduces the beautiful commercial value of the product.

Moreover, the automatic feeding mechanism for the above materials is generally complex and the surface of the machine casing is highly uneven, which is inconvenient for maintenance and inspection, and there are many opportunities for oil and fat to enter and adhere to it, making it difficult to clean. There is also the problem that it is difficult to do.

The present invention aims to provide a band saw machine with an automatic material feeding mechanism for cutting frozen foods that is useful for solving these problems.The specific configuration thereof will be described in detail based on the illustrated embodiment. , as follows.

That is, in FIGS. 1 to 3 showing the overall structure of the present invention, 1 is a machine case of a band saw machine, which includes a drive pulley storage chamber 2 that can be opened and closed, and a driven pulley storage chamber 3 connected directly above it. and a closed type feeding mechanism storage chamber 4 adjacent to the front side of the driving pulley storage chamber 2.

In this regard, in the illustrated example, the feed mechanism storage chamber 4 is separated from the drive pulley storage chamber 2 while being integrated with each other, but both chambers 2, 4
It may be fixedly installed in a detachable manner.

Reference numeral 5 denotes a freely rotatable driven pulley supported in the driven pulley storage chamber 3, and is raised and lowered by rotation of a band saw tensioning handle 6.

T is a driving pulley that is pivotally supported in the driving pulley storage chamber 2, and is rotated by a band saw driving motor 8 via belt transmission.

Reference numeral 9 denotes a band saw which is removably hung from both booles IJ-5 and 7, which form a pair of upper and lower boots, and is circulated in the vertical direction.
The sawtooth cuts the frozen food (hereinafter also referred to as material) straight.

Reference numeral 10.11 indicates a cutting thickness adjustment plate and a band saw dislocation prevention plate which are arranged on the left and right sides of the band saw 9, both of which are placed on the top table of the drive pulley storage chamber 2 in the machine housing 1. installed.

The cutting thickness adjustment plate 10 changes the size of the mutual imaginary distance W with the band saw 9 by moving forward and backward in the front and rear directions, thereby adjusting the cutting thickness of the material corresponding to the change.

On the other hand, the dislocation prevention plate 11 of the band saw 9 properly faces the back side of the saw blade, and prevents the dislocation of the band saw 9 when the band saw 9 is out of work.
This also prevents material from accidentally flying out forward during the movement process of the slide frame, which will be described later.

The following drive mechanism for automatically feeding materials is stored in the feeding mechanism storage chamber 4 of the machine housing 1.

That is, as is clear from FIGS. 1 to 3, the feeding mechanism storage chamber 4
Inside there is a drive motor 12 for feeding the material, and the motor 12.
and a speed reducer 14 that rotates the flywheel 13 by being driven by a belt.

Reference numeral 15 designates a pair of upper and lower guide rails installed in parallel in the storage chamber 4, and a slide frame 16 that engages with both rails 15 and is reciprocated in the left-right direction of the band saw 9, and a crank plate. The flywheel 13 is pivotally connected to the flywheel 13 by a crank arm 1T.

In other words, the rotary motion of the flywheel 13 is converted into a linear reciprocating motion of the slide frame 16 by the rank mechanism as described above, and the frame 16 moves the conveyor unit installed thereon, which will be described later, to the band saw 9. At the front position, it is moved in the left and right direction with a partial stroke.

A part of the slide frame 16 is located in the feeding mechanism storage chamber 4.
It is set as a table part 19 for supporting the conveyor unit by bending it out to the top of the storage chamber 4 through a long window 18 opened in the front surface of the storage chamber 4, and the top of the storage chamber 4 is provided on the bottom surface of the table part 19 for supporting the conveyor unit. The required number of rollers 20 that are transferred above are installed.

Reference numeral 21 denotes a conveyor unit installed on the table section 19 of the frame 16, which includes a cassette-type material storage case 22 that is removably fixed to the table section 19, and an upper and lower material storage case 22 that is removably fixed to the table section 19; A pair of endless chain conveyors 23 and 24 for feeding materials are used.

Both conveyors 23 and 24 are of course equipped with a sag, and the lower conveyor 24 is rotatably supported by the side plate of the storage case 22 so as to drive and feed the material while loading it thereon.

On the other hand, the upper conveyor 23 has a handle 25 and can be moved up and down within the storage case 22 so as to move the material under pressure using its own weight.

Lower chain conveyor 2 in conveyor unit 21
4 is a partial pitch so that the material can be automatically fed into the band saw 9 by the following mechanism when the frame 16 reaches the end point of the backward movement after cutting the material by the forward movement of the slide frame 16. advance by a minute.

That is, in FIGS. 4 and 5 showing the interlocking mechanism between the slide frame 16 and the conveyor unit 21, 26 is the machine housing 1.
This is a guide bed fixed to the outer surface of the feeding mechanism storage chamber 4 in , and its mounting position corresponds to the backward motion end position of the slide frame 16 .

2γ is a substantially triangular cam protrusion that is movably engaged on the bed 26, and by rotating an adjustment rod 28 screwed into this, it can be moved back and forth in the left and right direction, thereby moving the lower chain conveyor 24. The feed pitch of the material can be adjusted in advance.

A rotating shaft 29 is supported on the outer surface of the side plate of the material storage case 22, and a worm 30 is fixed to one end of the rotating shaft, and a ratchet wheel 31 is fixed to the other end.

The worm 30 meshes with a worm gear 32 fixed to the shaft end of the lower conveyor 24 that projects outward from the side plate of the storage case 22.

A pawl 33 pivotally attached to the storage case 22 is pressed into the ratchet wheel 31 so that it is always engaged with the pawl 33 .

At the other end of the rotating shaft 29, there is also a downward swinging arm 34.
The arm 34 is a pendulum hole that always maintains a hanging position, and as the slide frame 16 moves back, it collides with the cam protrusion 21 and is pushed up to keep the rotating shaft 29 constant. It is designed to rotate by the amount.

In the above configuration, cutting of the material is performed as follows.

That is, when the material M placed in the storage case 22 of the conveyor unit 21 is advanced by the chain conveyor 24 below it as shown by arrow A in FIG. 1 until it hits the cutting thickness adjustment plate 10. Next, the slide frame 16 supporting the unit 21 is moved forward in the direction of arrow B in FIG. The serrations cut the material straight to a certain thickness.

After the cutting is completed, the slide frame 16 is moved back in the opposite direction, and at the end point, the swing arm 34 on the conveyor unit 21 side hits the cam protrusion 2γ on the machine housing 1 side, and this detection function The rotating shaft 29 is rotated,
Through the meshing movement of the worm gear 32 and the worm 30, the rotation of the lower conveyor 24 advances the material M by a fixed pitch for the next cutting.

Then, as described above, the material M is cut during the forward movement of the slide frame 16, and this process is repeated continuously after u.

The locking of the material feed is achieved by the engagement of the pawl 33 with the pawl wheel 31, and the prevention of slippage of the material M, which changes in volume, is ensured by the downward pressure from the upper conveyor 23.

The feeding pitch of the material M can be adjusted in advance by sliding the cam protrusion 21 against the guide bed 26.
Even if the cut piece is broken into small pieces due to repeated cutting, the cut thickness adjustment plate 10 can adjust the cut thickness and stop the cut piece, allowing the work to be carried out accurately and efficiently.

As described above, in the band saw machine of the present invention, the machine housing 1 is formed from the pair of upper and lower pulley storage chambers 2 and 3 as well as the feeding mechanism storage chamber 4 adjacent to the front of the drive pulley storage chamber 2. A slide frame 16 cranked by a motor 12 via a flywheel 13, etc., and its slide guide rail 15 are enclosed in the storage chamber 4, and the frame 16 is reciprocated along the rail 15 in the left-right direction of the band saw 9. At the same time, a part of the frame 16 is installed as a long window 1.
The conveyor unit 2 extends outward from the conveyor unit 8 in a bent manner.
Since the unit 21 is defined as the supporting table part 19 of No. 1, the unit 21 is a cassette-type removably installed unit that automatically feeds material to the band saw 9 from the front. At the same time, the upper surface of the machine casing 1 can be made flat and simple, the entire surface including the table part 19 can be cleaned with high efficiency and reliability, and the chances of intrusion and adhesion of oil and fat can be reduced. 21 can be easily replaced, cleaned, maintained and inspected by anyone without the need for tools, and this can be said to be beneficial for hygiene when used for frozen foods.

In addition, especially in the case of the present invention, in addition to the cutting thickness adjusting plate 10 that receives the material sent by the conveyor unit 21 in advance, there is also a cutting thickness adjusting plate 10 for preventing the band saw 9 from leaving work and for suppressing the cutting pieces from scattering forward. Since the detachment prevention plate 11 is mounted on the table in the drive pulley storage chamber 2, unlike a conventional band saw machine that feeds material manually, even if it is automatically fed, there is no risk of the band saw 9 accidentally coming off. The dangers associated with this can be completely prevented, and by using it stably, it is possible to improve the product value by providing an excellent cutting surface that cannot be obtained with this type of cutting machine with a round knife. This corresponds to a special device for use in frozen foods.

Of course, being able to adjust the cutting thickness of automatically fed material also works effectively to prevent the above-mentioned slippage.

In other words, only by installing the band saw 9 slip-off prevention plate 11 can the band saw machine be put to practical use even with an automatic feed mechanism, and the warping of the cut pieces mentioned at the beginning, which occurs with this type of cutting machine with a circular blade, can be put to practical use. This means that cracks can be completely prevented.

In addition, the dislodgement prevention plate 11 not only prevents the band saw 9 from leaving, but also functions as a wall plate that prevents cut pieces cut by the automatic feed from scattering forward, so it has a rational design. This feature makes it easy to collect cut pieces and keep the table clean.

In any case, it can be said that it is a practical idea as a band saw machine for cutting frozen foods that can efficiently produce excellent cut pieces that cannot be obtained with a round knife due to automatic feeding.
