Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a belt releasing device in a food slicer for cutting food such as vegetables and meat.

[Prior Art] A main belt conveyor having an upper surface serving as a feeding path to a cutter, and a holding belt which is located above the main belt conveyor and is pressed against the main belt conveyor near the cutter to guide the processed food to the cutter. A food slicer in which a conveyor and a conveyor are arranged vertically is known. This food slicer transfers the processed food such as vegetables and meat to the cutter side by the main belt conveyor, clamps the processed food by the pressing belt conveyor and the main belt conveyor near the cutter entrance, and sequentially sends it to the cutter entrance, The cutter is used to perform the required cutting.

[Problems to be Solved by the Invention] Each of the main belt conveyor and the pressing belt conveyor has an endless conveyor belt suspended on a plurality of guide rolls including drive rolls. by the way,
Since these conveyor belts are used to press and feed the food to be processed, they tend to be contaminated with meat juice, vegetable juice, etc. when used, and it is necessary to remove them from the conveyor and properly wash them for hygiene management. For this reason, the frequency of detaching the conveyor belt is relatively high in the food slicer.

By the way, in a conventional conveyor belt, a tension roller for adjusting the tension of the conveyor belt, which is stretched around the guide rolls supported by the adherend frame in a tensioned state (see FIG. 1). The tension rollers 8 and 28) were operated to loosen the tension and to release it. Therefore, the tension roller usually moves its position inward and outward by screw rotation to adjust the tension, so it is necessary to rotate a large number of screws each time the belt is replaced. It was necessary to re-adjust the tension of No. 1 again and the replacement work was extremely troublesome. Further, as the frequency of adjustment increases, poor adjustment is more likely to occur, resulting in increased problems such as belt breakage and running failure due to belt overtension or looseness.

An object of the present invention is to provide a belt detaching device that does not have such conventional defects and can easily detach the belt.

[Means for Solving the Problems] According to the present invention, an auxiliary frame, which rotatably supports front guide rollers of a conveyor belt, can be rotated by a support shaft in front of mounting side plates on both sides of the main belt conveyor. In addition to being pivotally supported on both sides, a substantially semicircular locking groove is formed at the front end edges of the mounting side plates on both sides, and a linking shaft is attached to the auxiliary frame. By providing a locking shaft portion that has a substantially semi-circular cross-section that fits in the substantially semi-circular locking groove and that is disengaged from the locking groove by its approximately half rotation,
The auxiliary frame is supported on the mounting side plate by the support shaft and the link shaft.

Alternatively, an auxiliary frame rotatably supporting an abutment guide roller of the conveyor belt pressed against the main belt conveyor side is rotatably supported by a support shaft at the front of the mounting side plates on both sides of the pressing belt conveyor. In addition, substantially semicircular locking grooves are formed on the front end edges of the mounting side plates on both sides, and a linking shaft is attached to the auxiliary frame, and the substantially semicircular shape of the mounting side plate is attached to both ends of the linking shaft. A cross-section that is fitted in the locking groove has a substantially semicircular shape, and a locking shaft portion that is disengaged from the locking groove by substantially half rotation is provided, and the auxiliary frame serves as the support shaft and the link shaft. It is supported by the mounting side plate.

Further, in each of the belt releasing devices described above, the linkage shaft is movable in the width direction between the lock position and the open position, and the locking shaft portion having a substantially semicircular cross section is substantially semicircular at the lock position of the linkage shaft. A shift is made in the width direction with respect to the locking groove so that a circular shaft section having a cross section continuous with the locking shaft section is engaged with the locking groove. The lock mechanism is provided so that the stop shaft portion is aligned with the substantially semicircular locking groove in the width direction.

[Operation] In any of the belt conveyors, when the link shaft is rotated about half a turn, the engagement shaft portion is disengaged from the engagement groove, and the auxiliary frame is supported at one point by the support shaft, so that the belt tension force is increased. Tilts in the direction of loosening the tension about the spindle. Therefore, the conveyor belt can be easily removed from each guide roll.

At this time, in the case where the lock mechanism described above is provided,
At the lock position, the circular shaft section having a cross section that is continuous with the locking shaft section of the linking shaft is engaged with the locking groove, so that even if the linking shaft section rotates due to vibration during cutting operation, the linking shaft section The engagement does not come off from the mounting side plate, and the safety of the disengagement device can be secured. On the other hand, in order to release this engagement, if the linking shaft is moved in the width direction to the open position, the locking shaft portion having a substantially semicircular cross section is aligned with the substantially semicircular locking groove in the width direction and easily disengaged. The conveyor belt can be removed.

Next, the structure of the holding belt conveyor 24 arranged above the main belt conveyor 2 will be described in detail with reference to FIGS.

As shown in FIG. 1, a supporting metal 23 is erected at a substantially central position of the mounting side plate 3, and the supporting side plates 26, 26 of the presser belt conveyor 24 can be rotated by a support shaft 25 on the supporting metal 23. Supported by. The rotation is imparted with a moderation by a screw screwed to the support metal 23 and can be held at a required position.

The mounting side plates 26, 26 have a drive roller 27 on the base end side thereof,
A tension roller 28 is held at the center thereof, and further, contact guide rollers 29 are respectively supported via an auxiliary frame 35, and an endless conveyor belt 30 is stretched around each roller.

In this arrangement, the line segment connecting the position of the contact guide roller 29 and the center of the support shaft 25, which is the center of rotation, is substantially parallel to the material feeding passage, and as a result will be described later, the pressing belt conveyor 24 When is rotated upward about the support shaft 25, the front edge of the contact guide roller 29 always moves in a direction away from the cutter 46. Therefore, it is possible to bring the contact guide roller 29 as close as possible to the cutter 46 at the position where the pressing belt conveyor 24 is arranged, and it is possible to reliably supply the food to be processed. Cause

The drive roller 27 is provided with a gear 31 at an extension end further projecting from one of the mounting side plates 26, meshes with a drive system (not shown) at the position shown in FIG. 1 and is in communication therewith, and imparts a traveling force to the conveyor belt 30. . Further, the tension roller 28 has an end shaft inserted through a long hole 32 formed at the end of the mounting side plates 26, 26,
The adjusting screw 33 is screwed into this, and the tensioning force of the conveyor belt 30 is adjusted by moving the adjusting screw 33 along the elongated hole 32.

Furthermore, the contact guide rollers 29 are mounted on the mounting side plates 26, 26.
Is rotatably supported at the front edge of an auxiliary frame 35 supported by a support shaft 36 at the front part of the. This configuration will be described in more detail.

The auxiliary frame 35 supports brackets 38 and 38 on both sides of the front edge of the plate-shaped main plate 37, and the contact guide rollers 29 are rotatably supported on the front ends of the brackets 38 and 38. A linking shaft 39 is provided on the main plate 37. Locking shaft portions 39a, 39a having a substantially semicircular cross section are provided at both ends of the linking shaft 39, and a grip 39 is provided at a projecting end from the mounting side plate 26 on one side.
b is provided. The locking shafts 39a, 39a are mounted side plates.
26, 26 are fitted in and engaged with the substantially semicircular locking grooves 34, 34 formed at the front ends of the 26, 26, and the auxiliary frame 35 is supported at two points by the support shaft 36 and the link shaft 39, and in that state The contact guide roller 29 supported at the tip of the 35 ensures the traveling of the conveyor belt 30. On the other hand, the locking shaft portions 39a, 39a are provided with a shift in the width direction with respect to the substantially semicircular locking grooves 34, 34 as shown in FIG. The portions 39c, 39c are slightly engaged with the locking grooves 34, 34. Then, this width position is formed in the central portion of the linking shaft 39 and the linking circumferential groove 39d
In addition, the moderation ball 41b in the male screw 41a screwed to the main plate 37 is attached to the spring 41.
It is fitted by c and held by the urging force.

Thus, in such a configuration, the linkage shaft 39 is gradually rotated by the vibration accompanying the traveling of the conveyor belt 30, and the substantially semi-circular locking shaft portions 39a, 39a become substantially semi-circular locking grooves 34, Even if it shifts to a substantially half-rotation position where it is not linked with 34, the engagement with the locking grooves 34, 34 is maintained by the circular shaft portions 39c, 39c, and therefore the linked shaft 39 is disengaged from the mounting side plates 26, 26. There is no such thing. I.e.6,8
In the illustrated position, the link shaft 39 is in the locked position. The lock mechanism can also be applied to the link shaft 20 of the main belt conveyor 2.

To release the link shaft 39 from the engagement with the auxiliary frame 35, the handle 39b is pulled as shown by the arrow in FIG. Set to the open position. When this is pulled, the outer shape of the main shaft 39e slightly inside the linking shaft 39 is made slightly larger than the diameter of the substantially semicircular locking grooves 34, 34, and the main shaft 39e is mounted on one side of the locking groove 34. 26 Positioned by abutting the inner surface. Then, in this state, the circular shaft portions 39c, 39c are excluded from the substantially semicircular locking grooves 34, 34, and the substantially semicircular locking shaft portions 39a, 39a become substantially semicircular locking grooves 3.
I try to match 4,34. Therefore, this linking shaft 39
About half a turn, and as shown in FIG. 7, a substantially semicircular locking shaft 39a, 39
The engagement between a and the substantially semicircular locking grooves 34, 34 is released. Therefore, the auxiliary frame 35 serves as a single-point support by the support shaft 36, and the tension force of the conveyor belt 30 causes the support shaft 36 to tilt about the support shaft 36 in a direction to relieve the tension of the link shaft 39. That is, it tilts in the direction of the arrow in FIG. This tilting relieves the tension of the conveyor belt 30 and makes it easy to remove it.

With such a configuration, vegetables on the main belt conveyor 2,
When food such as meat is supplied, it is conveyed to the entrance of the cutter 46 by the conveyor belt 10 of the main belt conveyor 2, and the contact guide roller 29 of the presser belt conveyor 24 is brought into pressure contact with the conveyor belt 10 and the conveyor near the entrance. While being sandwiched by the belt 30, it is sent to the cutter 46 to be cut and discharged from the shooter 47.

If this processing operation is continued, the conveyor belts 10 and 30 become soiled with vegetable juice or the like, and it is necessary to properly clean them for hygiene management.

Therefore, the pressing belt conveyor 24 is rotated upward about the support shaft 25. At this time, as described above, the front edge of the contact guide roller 29 always moves in the direction away from the cutter 46 and is not damaged by the cutter 46.

When replacing the conveyor belt 10, the linking shaft
Rotate the handle 20b of 20 to lock shafts 20a, 20a and lock grooves 22, 2.
The conveyor belt 10 can be easily removed by releasing the engagement with 2 and tilting the auxiliary frame 16 about the support shaft 17 and releasing the tension by the front guide roller 9.

Also, when replacing the conveyor belt 30,
By pulling the handle 39b after rotating the handle 39b, the auxiliary frame 35 is tilted about the support shaft 36, the contact guide roller 29 is retracted, and the tension is released to easily remove the conveyor belt 30. Can be made.

As described above, according to the present invention, it is not necessary to adjust the tension rollers 8 and 28, and the linking shafts 20 and 39 do not require any troublesome operation such as pulling out from the auxiliary frames 16 and 35, respectively, and are simply rotated. Conveyor belt 1
The exchange of 0 and 30 can be performed very easily.

[Advantages of the Invention] As described above, according to the present invention, the tension of the conveyor belt can be released by operating the linkage shaft substantially half a turn. Therefore, the conveyor belt can be replaced very easily and the tension of the conveyor belt can be changed. Since it is not necessary to adjust the rollers and the like, the tension state of the conveyor belt can be easily reproduced, and there is an excellent effect that the processing work can be continued without any trouble after the replacement.

Further, the linking shaft is shifted in the width direction with respect to the locking shaft portion having a substantially semicircular cross section with respect to the locking groove having a substantially semicircular shape, and the circular shaft portion having a cross section continuous with the locking shaft portion is engaged with the locking groove. When the locking mechanism adapted to be engaged is applied, the linkage shaft does not rotate due to the vibration or the like during work and the linkage shaft is not disengaged, and the safety of the disengagement device can be secured. There is an effect.
