In connection with the meat box reciprocating meat slicer, the thickness adjustment plate is linked to the setting of the feed amount of the material by rotating the manual operation shaft. It is characterized in that it can be easily removed to facilitate a desired work.
[0002]
[Prior art]
In a conventional meat box reciprocating-type meat slicer, the slicer in which the thickness adjustment and the setting of the material feed amount are interlocked by rotating the manual operation shaft provided on the side surface of the machine base. The prior application is Japanese Patent Application No. 8-298052.
[0003]
[Problems to be solved by the invention]
Since the slicer of the prior application has the thickness adjusting mechanism and the material feeding mechanism connected to one manual operation shaft as described above, it becomes difficult to attach and detach the thickness adjusting plate when cleaning the slicer after use. This caused a technical problem that it was difficult to clean the back side of the thickness adjusting plate.
[0004]
On the other hand, in recent years, hygienic maintenance management of food machinery has been strictly followed, and it is easy to attach and detach the thickness adjustment plate even in meat slicers that have a technically difficult thickness adjustment mechanism and material feed mechanism linked. It was a problem to be solved.
[0005]
[Means for Solving the Problems]
Accordingly, the present invention rotates the first rotation transmission mechanism connected to the thickness adjustment shaft and the second rotation transmission mechanism connected to the material feed adjustment shaft on the manual operation shaft provided on the side surface of the machine base. In the meat slicer of the meat box reciprocating type meat slicer, which is connected so that the thickness adjustment and the setting of the material feed amount are interlocked by rotating the manual operation shaft, the pinion at the inner end of the thickness adjustment shaft A support shaft of the thickness adjusting plate that is engaged with the rack portion and moved along with the rotation of the thickness adjusting shaft is provided so as to be able to escape from the bearing hole of the base portion by one rotation of the thickness adjusting shaft. A clutch for interrupting rotation transmission from the second rotation transmission mechanism is provided, and a stopper is provided on the support shaft of the thickness adjustment plate to stop the thickness adjustment plate at the zero position by contacting the base portion. For cover member of thickness adjustment shaft A thickness scale based on the zero thickness position is displayed, and the indicator needle of this scale is held between the knob attached to the outer end of the thickness adjustment shaft and the friction plate, and the indicator needle is The meat slicer is provided with a pointer stopper that stops at the zero position.
[0006]
The slicer according to the present invention first rotates the manual operation shaft to adjust the thickness adjusting shaft and the material feed adjusting shaft to the adjustment zero position. Next, the clutch that connects the second rotation transmission mechanism and the material feed adjustment shaft is released to shut off the transmission to the material feed mechanism, and when the manual operation shaft is turned to the maximum and the thickness adjustment shaft is rotated once, the pinion Since the support shaft of the thickness adjusting plate which has been disengaged from the front can be extracted forward from the bearing hole of the base portion, the thickness adjusting plate can be easily removed.
When the thickness adjustment plate is removed, the indicator needle that was at the zero position of the thickness scale follows the maximum rotation of the thickness adjustment shaft and makes almost one turn around the cover member. Stopped.
Further, the rotation of the thickness adjusting shaft after the indicating needle is stopped by the pointer stopper is performed without any trouble due to the slip of the indicating needle sandwiched between the knob and the friction plate.
[0007]
Next, when reattaching the thickness adjustment plate removed together with the support shaft, insert the support shaft into the bearing hole of the base portion, and engage the manual operation shaft while engaging the rack portion with the pinion at the inner end of the thickness adjustment shaft. By rotating to the zero position side, the drawing into the bearing hole is performed smoothly.
The maximum pull-in of the support shaft of the thickness adjustment plate, that is, reaching the zero adjustment position, can be easily detected by the stopper that comes back together with the support shaft coming into contact with the base, and anyone can install it. Can be redone.
[0008]
In this return process, the indicator needle rotates with the rotation of the thickness adjusting shaft, and is stopped by the pointer stopper to return to the zero position. The indicator needle after returning to the zero position slips in the same manner as when the support shaft is pulled out, and does not hinder the rotation of the thickness adjusting shaft.
When the thickness adjusting mechanism returns to the zero position in this way, the material feeding mechanism also starts from the zero position by returning the previously removed clutch.
In terms of words, it is cumbersome as described above, but the operation of attaching and detaching the slicer thickness adjusting plate can be done very easily by following the procedure, and it can be done easily even by non-experts. Also, the thickness adjustment and material feed can be smoothly returned to the zero position.
The present invention solves the above problems as described above.

As shown in FIG. 1, the slicer S includes a blade A that rotates vertically on one side of a machine base F, is connected to a crank 1 that rotates on the machine base F, and is supported by a rail 2 on the front and rear sides. It has a meat box B that reciprocates on the machine base F along the rotation surface of the blade A.
[0010]
The manual operation shaft 3 rotatably attached to the side surface of the machine base F has a thickness adjusting shaft provided with a first rotation transmission mechanism 4 having one end coaxially fixed along the left side of the machine base F. The second rotation transmission mechanism 6 connected to the first rotation transmission mechanism 4 so as to rotate integrally with the first rotation transmission mechanism 4 is connected to the material feed adjusting shaft 7 provided along the right side of the machine base F. Thus, the adjustment of the thickness of the slicer and the setting of the feed amount of the material are linked to perform two adjustments simultaneously.
[0011]
As shown in FIG. 2, the thickness adjusting shaft 5 is inserted into a base portion 8 whose tip is provided on the machine base F, and the pinion 9 at the inner end is perpendicular to the thickness adjusting shaft 5 and is perpendicular to the base portion. 8 is engaged with the rack portion 13 of the support shaft 12 of the thickness adjusting plate 11 inserted as shown in FIG. 3 from the bearing hole 10 opened on the other side surface of the shaft 8, thereby converting the rotation into sliding of the thickness adjusting plate 9. .
[0012]
In this embodiment, as shown in FIG. 2, the wedge shaft is inserted so that the clamp shaft 14 is inserted into the base portion 8 in parallel with the thickness adjusting shaft 5 so as to face the inner end of the clamp shaft 14. The clamps 15 and 15 are pressed against the support shaft 12 of the thickness adjusting plate 11 in the bearing hole 10 to fix the thickness adjusting plate 11 together with the support shaft 12 to the adjustment position. Clamping the support shaft 11 in this manner is an optional matter not included in the configuration of the present invention.
[0013]
As shown in FIGS. 1, 2, and 3, the support shaft 12 is integrally formed with a flat plate-like holder 16 that connects the shaft 12 and the thickness adjusting plate 11 along the side surface of the base portion 8 at the outer end. The thickness adjusting plate 11 is supported at the thickness adjusting zero position by bringing the tip of the screw-shaped stopper 17 screwed into the holder 16 into contact with the base portion 7 as shown in FIG.
[0014]
A sprocket 18 on the output side of the first rotation transmission mechanism 4 is fixed to the base end portion of the thickness adjusting shaft 5 supported on the base portion 7 as described above so as to cover the sprocket 18. An annular cover member 19 is attached. A thickness scale (not shown) with the thickness adjustment zero position as a reference point is displayed on the peripheral surface of the cover member 19.
[0015]
In addition, the outer end portion of the thickness adjusting shaft 5 penetrating the cover member 19 is provided with an indicator needle 23 having a base sandwiched between a knob 21 with a spring 20 and a washer-like friction plate 22. It is possible to know the thickness of the slice piece adjusted according to the rotation angle of the adjustment shaft 5.
Further, the indicator needle 23 is restrained so as not to exceed the zero position of the thickness scale at a position where the side edge is brought into contact with the pointer stopper 24 protruded from the end surface of the cover member 19.
[0016]
A material feed adjusting shaft 7 provided on the right side of the machine base F as shown in FIG. 4 and driven by the manual operation shaft 3 via the second rotation transmission mechanism 6 is connected to the output end of the rotation transmission mechanism 6. The sprocket 6 ′ is loosely fitted, and is configured to be rotated following the rotation operation of the manual operation shaft 3 or to be non-rotation by switching operation of the clutch 25 that is coaxially mounted.
[0017]
In this embodiment, the clutch 25 is composed of a connecting hole 26 provided on the side surface of the sprocket 6 ′, a connecting rod 28 that is biased by the coil spring 27 and moves the tip into and out of the hole 26, the coil spring 27, It comprises a hub 31 that is equipped with a hook 28 and a clutch switching knob 29 fixed to the outer end of the connecting hook 28, and is provided to rotate integrally with the outer end of the material feed adjusting shaft 7 via a key 30.
[0018]
When the clutch 25 is in the coupled state shown in FIG. 4, the material feed adjusting shaft 7 is driven by the second rotational drive mechanism 6 via the sprocket 6 ′, the connecting rod 28, and the hub 31. A sliding body 32 for screwing the shaft portion 7 ′, a connecting rod 33 for screwing the screw shaft portion 33 ′ to the sliding body 32, and a material feed base 34 fastened to the tip of the connecting rod 33 are illustrated in the left-right direction. The material feed base 34 is moved to a position corresponding to the thickness adjustment amount adjusted by the rotation operation of the manual operation shaft 3.
Note that the material feed base 34, like a known slicer, swings the feed lever 35 when the meat box B is reciprocating, rotates the material feed shaft 36 halfway, and moves the upper and lower parts attached to the meat box B. The material feeding conveyors 37 and 38 are intermittently driven.
[0019]
Further, when the clutch switching knob 29 is pulled to cause the connecting rod 28 to escape from the connecting hole 26, the material feed adjusting shaft 7 is released from the clutch connection, and therefore the manual operation shaft 3 can be rotated only by moving the thickness adjusting plate 11 back and forth. It will be transmitted to.
When the clutch 25 is in an open state, the pulled connecting rod 28 is rotated by 90 °, and a pin 39 inserted laterally through the connecting rod 28 is screwed into the outer end surface of the hub 31. It is maintained by being hooked in the cross groove 40 '.
[0020]
In FIG. 4, reference numeral 41 denotes a manual material feed adjustment in which the material feed amount can be corrected at any time by moving the material feed base 34 in addition to interlocking with the thickness adjusting plate 11 by rotating the manual operation shaft 3. In the apparatus, a chain transmission mechanism 43 spanned between an operation shaft 42 that is rotatably mounted parallel to the material feed adjusting shaft 7, a connection rod 33 of the material feed base 34, and a slide provided on the connection rod 33. The transmission guide groove 44 includes a transmission pin 46 inserted from one sprocket 45 of the chain transmission mechanism 43.
[0021]
The specific structure of the clutch 25 configured as described above is not limited to the aspect of the embodiment, and it goes without saying that the design can be changed to an appropriate clutch structure in accordance with the gist of the present invention.
Further, the attachment of the manual material feed adjusting device 41 and the specific configuration of the transmission mechanism during the transmission of the rotation of the material feed adjusting shaft 7 to the movement of the material feed base 34 are not included in the configuration of the present invention. Belonging to the matter.
[0022]
Next, the attaching / detaching operation of the thickness adjusting plate 11 will be described.
In this embodiment, when the thickness adjusting plate 11 is removed, as described above, the manual operation shaft 3 is first rotated and the thickness adjusting shaft 5 and the material feed adjusting shaft 7 are adjusted to the adjustment zero position. Next, the clutch 25 that connects the second rotation transmission mechanism 6 and the material feed adjusting shaft 7 is opened, the transmission to the material feed mechanism is shut off, the clamp shaft 14 is loosened, and the fixing of the support shaft 12 is released. When the manual operation shaft 3 is turned to the maximum and the thickness adjusting shaft 5 is rotated once, the support shaft 12 of the thickness adjusting plate released from the meshing with the pinion 9 can be pulled out from the bearing hole 10 of the base portion 8. The thickness adjusting plate 11 and the holder 16 can be easily removed.
[0023]
The indicator needle 23 that was in the zero position of the thickness scale when the thickness adjusting plate 11 is removed follows the rotation of the thickness adjusting shaft 5 and makes almost one turn around the cover member 19, but the pointer stopper 24 from the opposite direction. The rotation of the thickness adjusting shaft 5 after being stopped and the indicating needle 23 being stopped by the pointer stopper 24 is performed without any trouble by the slip of the indicating needle 23 sandwiched between the knob 21 and the friction plate 22.
[0024]
Next, when the thickness adjusting plate 11 is remounted, the holder 16 is held, the support shaft 12 is inserted into the bearing hole 10 of the base portion 8, and the rack portion 13 is engaged with the pinion 9 at the inner end of the thickness adjusting shaft 5. The manual operation shaft 3 is rotated to the zero position side while being pulled, so that the drawing into the bearing hole 10 is performed smoothly.
The pull-in of the support shaft 12 of the thickness adjusting plate 11 reaches the maximum, that is, the adjustment zero position easily by the stopper 17 moving integrally with the support shaft 12 and the holder 16 being in contact with the base portion 8. It can be sensed and anyone can reattach the thickness adjusting plate 11.
[0025]
Further, in this returning process, the indicator needle 23 rotates together with the rotation of the thickness adjusting shaft 5 and is stopped by the pointer stopper 24 to return to the adjustment zero position. Since the indicating needle 23 after returning to the zero position is stopped by the pointer stopper 24 and slips in the same manner as when the support shaft 12 is pulled out, the rotation of the thickness adjusting shaft 5 is not hindered.
When the thickness adjusting mechanism returns to the zero position in this way, the material feeding mechanism also starts from the adjusting zero position by returning the clutch 25 previously removed.
[0026]
