Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an upper conveying device for a meat slicer.

[Conventional technology]

 A conventional technique will be described with reference to FIG.

A roller shaft support member 12 having a hexagonal through hole 11 is pivotally supported at the tip of the arm 10. Roller shaft support member 12
Is transmitted by the chain 18 from the drive of the meat box 5 and rotates. The feed roller 8 is mounted on a hexagonal roller shaft 13, and a sleeve 15 is fixed to the intermediate portion of the roller shaft 13 by a roll pin 19 next to the feed roller 8. Further, the roller shaft 13 of the sleeve 15 on the side opposite to the feed roller 8 side
Is loosely fitted in the through hole 11 of the roller shaft support member 12, and the knob 16 is screw-fitted into the threaded portion 14 provided at the tip end to be integrated with the roller shaft support member 12. With the roller shaft 13 set on the arm 10, the roller shaft support member 12 and the knob 16 are in flat contact with each other.

[Problems to be solved by the device]

On the other hand, since the hexagonal through hole 11 of the roller shaft support member 12 and the roller shaft 13 are loosely fitted, there is a gap inside. Therefore, when the tightening force of the knob 16 is small, the roller shaft support member 12 and the knob 16 are in flat contact with each other, so that the roller shaft support member
There is a gap between 12 and the knob 16, and when the meat box 5 reciprocates and the meat chunk 6
While the sheet is being fed, the feed roller 8 is swung in the direction of the arrow B.

This causes a problem that the sleeve 15 and the knob 16 move in the radial direction with respect to the roller shaft support member 12, and both end surfaces of the roller shaft support member 12 are worn. If this is repeated, the fitting portion between the through hole 11 and the roller shaft 13 is also worn, and the backlash in the direction of the arrow B becomes large, and eventually the feed roller 8 during the slicing work has side surfaces of the round blade 2 and the meat box 5. However, there was a problem that the pieces of the feed roller 8 entered into the sliced pieces of the meat block 6 due to the contact with the broken pieces.

Further, since the feed amount of the feed roller 8 is not stable, there is a drawback that the slice pieces fed to the round blade 2 side by the feed roller 8 have uneven thickness.

An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art, prevent rattling of an upper transfer device of this type, and improve slice accuracy.

[Means for Solving the Problems]

In order to achieve the above object, the present invention has an arm that swings up and down about a fulcrum arranged outside the meat box, and a roller shaft support member is rotatably provided at the tip of the arm.
A roller shaft is loosely fitted in the roller shaft support member, and a feed roller is mounted on the outer periphery of the roller shaft, and a knob is screwed into a screw portion provided at an end of the roller shaft opposite to the feed roller. In the meat slicer in which the roller shaft supporting member and the roller shaft are fixed, a taper portion is provided at the end of the roller shaft supporting member that comes into contact with the knob, and the knob is also provided with a taper portion corresponding to the taper portion. When the knob is fastened to the threaded portion, the taper portion of the knob and the taper portion of the roller shaft support member are taper-fitted to each other.

[Action]

With the above configuration, when the knob of the roller shaft is tightened on the threaded portion of the roller shaft, the taper portion of the knob and the taper portion of the roller shaft support member are fitted to each other, so that the roller shaft support member and the roller shaft are fed by looseness. The roller is prevented from swinging, and the feed roller does not come into contact with the round blade during the meat slice slicing operation.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a side view of a meat slicer equipped with an upper conveyance device according to the present invention, FIG. 2 is a partially enlarged arrow view seen from the direction A in FIG. 1, and FIG. It is a front view.

In the figure, a round blade 2 rotatably driven by a motor (not shown) on a round blade base 3 provided upright in one corner of a machine base 1 is rotatably supported by a round blade driving shaft supported in the round blade base 3 to form a meat block. The meat box 5 for storing 6 reciprocates toward the round blade 2 from the electric motor (not shown) through the crank device 20 using the rail 4 fixed on the machine base 1 as a guide. The meat box 5 is provided with a conveyor 7 that sequentially feeds the chunks of meat 6 toward the round blade 2 by a predetermined thickness.

One end of an arm 10 is swingably supported by a shaft 9 on the outer side of the meat box 5. The other end of the arm 10 supports a feed roller 8, which is arranged on the meat block 6 placed on the conveyor 7, and the feed roller 8 is transmitted from the drive device 21 of the meat box 5 through the chain 18. Then, the meat block 6 is rotated together with the conveyor 7 and fed to the round blade 2 side by a predetermined thickness.

Next, a specific configuration around the feed roller 8 will be described with reference to FIGS. 2 and 3.

A roller shaft support member 12 having a hexagonal through hole 11 in the arm 10 is rotatably supported in the horizontal direction, and the through hole 11 has a
A hexagonal roller shaft 13 having an outer periphery similar to the through hole 11 is loosely fitted,
A sleeve 15 is provided on the outer periphery of the roller shaft 13 to support the roller shaft 12
It is fixed by a roll pin 19 so as to abut the left end of the. Roller shaft 13 and sleeve 15 are in contact with each other
The taper part 13 is on the left end of 13 and the right end of the sleeve 15.
a and 15a are formed. Similarly, the feed roller 8 is mounted on the outer periphery of the roller shaft 13 so as to contact the left end of the sleeve 15. The chain 18 meshes with a sprocket 17 provided on the outer periphery of the roller shaft support member 12, and the roller shaft support member 1
2. The feed roller 8 is rotated via the roller shaft 13.

Further, a knob 16 is screwed into a threaded portion 14 provided at the end of the roller shaft 13 opposite to the feed roller 8 so that the knob 16 is located on the side surface of the arm 10. Further, a tapered portion 12a is formed at the end of the roller shaft support member 12 that comes into contact with the knob 16, and the knob 16 is also formed with a tapered portion 16a corresponding to the tapered portion 12a.

In the above configuration, when the knob 16 is fastened to the screw portion 14 of the roller shaft 13, the taper portion 16a of the knob 16 and the taper portion 12a of the roller shaft support member 12 are fitted to each other, so that the knob 16 on the same axis and the roller Shaft support member 12, roller shaft 13, sleeve
15 members are securely connected to each other, the feed roller 8 is prevented from being shaken due to the looseness between the roller shaft 13 and the through hole 11 of the roller shaft supporting member 12, and during the slicing work of the meat mass 6 by the round blade 2. The feed roller 8 never contacts the round blade 2.

[Effect of device]

According to the present invention, since the roller shaft support member and the knob that are axially supported by the arm of the meat box are provided with the tapered portions and are fitted to each other by the taper, the respective members on the same axis can be surely connected. It is possible to prevent the feed roller from swinging due to backlash between the roller shaft and the through hole of the roller shaft support member.

Further, since the feed amount of the feed roller is stable, it is possible to realize a meat slicer with less slice thickness unevenness and excellent slice precision.
