Description

DETAILED DESCRIPTION OF THE INVENTION This invention has a method of receiving the front end of a slice piece being cut into a round blade on the back side of the round blade into a conveyor belt that rotates at the same speed as the cutting speed of the material. The present invention relates to a receiving device for a meat slicer equipped with a conveyor frame that moves at the same speed in the cutting direction of the meat slicer.

A conventional device of this type includes, for example, Patent Publication No. 96767 filed in 1972, which was filed by the present applicant. In the device of this earlier application, the conveyor belt stretched over the conveyor frame rotates in one direction at the same speed as the cutting speed, so the slices can be conveyed without causing any expansion or contraction when receiving them from the slicer. When discharging the slices, either turn them over at the folded end of the conveyor belt that rotates on one side, or let them fall.
Alternatively, since the comb-shaped transfer member inserted between the uneven stripes provided on the conveyance belt is turned over to drop the slices to a predetermined position, when the slices are discharged from the receiving device, It has the disadvantage that it expands and contracts, making it unsuitable for slicing soft materials such as raw meat. Also, as another example,
There is also an automatic arrangement device for cut meat referred to in No. 14486, but this device is equipped with a comb-shaped delivery device that can be reversed to a receiving device installed at the position where the slices separated by the round blade fall. As a result, the slices maintain their own shape without being supported by anything, twice: from the time they start cutting until they fall onto the receiving device, and once when they turn around and fall from the comb-shaped transfer device. This results in repeated situations where the meat is likely to be damaged, making it even more unsuitable as a device for automatically receiving slices of raw meat than the former. Furthermore, there is a meat slice receiver disclosed in Japanese Utility Model Publication No. 39-22773, but this device also has the same drawback as the first two in that the slices must be turned over when being discharged from the receiver.

Therefore, the present invention aims to receive the front end of the slice piece that the round blade is cutting on the back side of the round blade into a conveying belt that rotates in one direction at the same speed as the cutting speed of the material, while also moving in the same direction as the round blade in the cutting direction of the material. The front end of a conveyor frame of a certain length that moves at a high speed is supported reciprocatingly on a vertical track parallel to the front end surface of the meat box, and the rear end of the other end is supported reciprocatingly on a horizontal track that intersects the vertical track. By freely supporting the conveyor frame, one end of the conveyor frame of the receiving device reciprocates in the vertical direction along the front end surface of the meat, and the other end reciprocates in the horizontal direction. To provide a receiving device for a meat slicer in which a rotating conveyance belt is circulated at the same speed as the cutting speed of the material, and slice pieces can be placed and stacked at a predetermined position from the rear end of a conveyor that reciprocates in a horizontal direction without reversing them. It is something.

The present invention will be described below with reference to embodiments shown in the drawings.

In the embodiment shown in FIGS. 1 and 2, A is a round blade, B is a meat box that automatically feeds loaded material meat blocks,
C is a conveyor of a receiving device that receives the slice S obtained by cutting the material fed out from the meat box B by the round blade A and conveys it to a predetermined position.

The round blade A is attached to the center of an elevating frame 2 whose both sides are loosely fitted to a pair of left and right columns 1 erected in the form of a gate on the machine base F, and motors M ₁ and 2 are mounted on one side of the machine base F. A crankshaft 5 rotates as a result of a belt transmission mechanism 4 stretched over a link arm 3 of the joint, and a crankshaft 5 that is driven by a motor _M2 provided at the bottom of the machine base F, and cranks 6 fixed to both ends of the coaxial shaft 5. The meat box B is moved up and down along the front end surface B' of the meat box B installed on the machine stand F, driven by a connecting rod 7 that connects both sides of the lifting frame 2 and the crank 6.

The conveyor C of the receiving device has a pair of left and right conveyor frames f, and front and rear (first and second) conveyor frames f of the same frame f.
rotating shafts 8 and 9 that pass through the upper and lower ends of the figure, respectively;
A conveyor belt 10 stretched between rotating shafts 8 and 9 is provided,
The front rotating shaft 8 is supported on the back of the lifting frame 2, and the pinion gear 11 attached to one end (right side in FIG. 1) of the front rotating shaft 8 is mounted on a rack 12 installed vertically parallel to the column 1. The rollers 13 provided at both outer ends of the rear rotating shaft 9 are fitted into the rails 14 on both sides horizontally suspended on the machine base F, and the pinion gear 15 attached to one side of the coaxial shaft 9 is set to idle. A one-way roller is interposed between the front and rear rotating shafts 8, 9 and the pinion gears 11, 15 attached to each one, meshing with a rack 17 installed on the machine base F in parallel with the rail 14, with a gear 16 interposed therebetween. Clutches 18 and 19 are interposed.

The front end f' of the conveyor frame f has a circular blade A with the column 1 as a vertical track a shown in FIG.
It also moves at the same speed in the cutting direction of the material, and reciprocates together with the lifting frame 2 in parallel with the front end surface B' of the meat box B.
The rear end f'' of the other end of the frame, which is a certain distance from the front end f', is connected to the rail 14 as a horizontal track b intersecting the vertical track a, as shown in FIG. When the conveyor belt 10 moves to the left in Figures 2 and 3, and when it ascends, it moves to the right and reciprocates in the horizontal direction.Also, when the lifting frame 2 descends and cutting of the material begins, the conveyor belt 10 is moved by the round blade A. While receiving the front end of the slice piece S, which is cut from above and curved back to the back side of the round blade A, on the front end of the circular arc shape,
At the same time as it descends, it is driven by the pinion gear 11 which meshes with the rack 12 and descends while rotating counterclockwise in the drawing, and rotates in one direction at the same speed as the cutting speed of the material. At this time, the pinion gear 15 at the rear end of the conveyor frame connects the rack 1 via the idle gear 16.
7 rotates clockwise, but the same gear 15
Due to the action of the one-way clutch 19 fitted in the one-way clutch 19, the one-way rotation of the conveyor belt 10 is constructed so as not to interfere. Furthermore, when the lifting frame 2 is raised, the one-way roller clutch 19 is connected to the rear rotary shaft 9 at the rear end of the conveyor frame that moves backward, and transmits the counterclockwise rotation of the pinion gear 15.
During the downward movement, the other one-way roller clutch 18 connected to the front rotation shaft 8 is released, and the conveyance belt 10 is configured to continue rotating counterclockwise during the backward movement. Reference numeral 20 denotes an intermittent drive type carry-out conveyor provided directly below the reciprocating position of the rear end f'' of the conveyor frame f in the same direction.

In carrying out the present invention, if the circulation of the conveyance belt 10 is to be maintained at a predetermined speed, a drive mechanism with speed control, for example, may be used instead of the drive mechanism consisting of a rack, pinion, one-way roller clutch, etc. used in this embodiment. A motor drive system or the like may also be used.

According to the present invention configured as described above, the round blade A
The sliced pieces S are received on the conveyor belt 10 with almost no expansion or contraction, and are then discharged from the rear end of the conveyor belt 10, which continues to rotate in the same direction during the return movement of the conveyor frame f. During the discharge process, the rear end of the conveyor frame f
Since f'' moves horizontally along the backward movement direction at the same speed as the discharge speed of the conveyor belt 10, its front end is brought into contact with the discharge conveyor 20 waiting directly below the discharge position or on the tray placed on it. sliced piece S
, the movement of the rear end f'' and the rotation of the conveyor belt 10 are 1
By being compatible with 1 pair, the contact surface is gradually expanded without causing expansion or contraction, and by the end of the return stroke, the transition onto the carry-out conveyor or tray is completed (3rd (See Figures D and E).
Further, the above-described receiving and discharging operation is repeatedly performed at each predetermined position.

As described above, according to the present invention, the slice pieces received by the receiving device can be placed at a predetermined discharge position without being turned over and with almost no expansion or contraction, so that the shape at the time of cutting can hardly be changed. Transfer it onto a flat surface. Therefore, by stacking the desired number of slices on the same plane, or stacking the desired number of slices by moving the conveyor intermittently one by one, and connecting the slices to an automatic packaging and weighing device. Therefore, it is highly anticipated that meat packaging will become fully automated.

Next, in this embodiment, as shown in FIG. 3, the reciprocating stroke of the conveyor frame f is
After the cutting stroke c in which the conveyor frame is completely separated by the round blade A, there is a margin stroke d in which the front end part f' of the conveyor frame continues to descend together with the round blade A, and as shown in Figs. , the rack 12 provided along the vertical track a is loosely fitted into a support member 21 that supports the top and bottom of the rack 12 so that it can be raised and lowered with respect to the machine base F, while the rack 12 is mounted on a cam 22 fixed to the crankshaft 5. By connecting the tip of the lever 23 that follows and swings to the lower end of the rack 12 to provide a mechanism D for pushing the lever 23 upward, the lever 23 swings upward following the cutting stroke c, thereby achieving the margin stroke. At time d, the rack 12 is raised against the front end f' of the conveyor frame, which continues to move downward, thereby causing the front rotating shaft 8 to rotate rapidly, and cutting by the round blade A is completed to completely cut the sliced piece S. By causing the conveyance belt 10 that has been received by the carrier belt 10 to undergo a push-feed rotation and move the slice piece S to the rear end of the conveyor belt 10, the transfer of the slice piece S during the above-mentioned return stroke can be prevented. It was designed to be carried out without delay. In Fig. 3, m is the material (meat loaf), S is the sliced piece, c' is the cutting start stroke, e is the return stroke, e' is the return stroke,
Other symbols are the same as in FIGS. 1 and 2.

Next, in the embodiment shown in FIG. 4, the round blade A is attached to the tip of an arm 25 whose rotation center is the main rotation axis 24 of the slicer. The front end surface is placed on the rotation trajectory of this round blade A.
B' is positioned and the meat box B is installed, while the synchronous rotating shaft 26 rotates synchronously with the main rotating shaft 24.
and a cam 27 fixed to the same shaft 26. A U-shaped frame 28' is provided at the upper end of the elevating rod 28 extending upward from the elevating device E, and the receiving conveyor is attached to this frame 28'. Connect both sides of the front end f' of the conveyor frame f of C, and connect the above-mentioned lifting rod 2.
8 is the vertical track a, the rail 14 is provided on the machine base F of the slicer and this is a horizontal track b, and the rear end f'' of the conveyor frame f is supported on the horizontal track b, similar to the embodiment. The conveyor C of the receiving device is driven in accordance with the cutting cycle of the round blade A.In this embodiment, the round blade A is provided at both ends of an arm 25 extending in the direction of rotation diameter, and the main rotation axis 24 is cut twice during one rotation, and in synchronization with this, the receiving conveyor C also receives twice and repeats the discharging operation. Members other than the above are designated by the same reference numerals as those in the embodiment. The explanation will be omitted.

In this embodiment configured as described above, the receiving conveyor C receives the slice S as in the embodiment, and the slice S is placed on the discharge conveyor 20 without being reversed and with almost no expansion or contraction. Can be transferred flat.
