Description

[Detailed Description of the Invention] Conventionally, the work of picking up foods such as shumai from an automatic food manufacturing machine from the conveyor and packing them into a tray has been done manually. If the food production capacity of the machine is low, the manual work described above can be sufficient, but if the food production capacity is high, it will require a lot of manpower to fill the Ikioi Dry, which can be done manually by a small number of people. It will require.

The present invention provides an apparatus that mechanically controls tray filling work of food products in order to follow the high-speed, high-efficiency production of food products.

Hereinafter, one embodiment of the present invention will be described based on the drawings. A tray conveyor 2 is provided at the lower end of the food delivery conveyor 1, and pillars 3, 3 are erected on both sides facing the end of the food delivery conveyor 1. A rotating shaft 4 is installed and supported between the upper ends of these columns 3, 3, and a pair of hanging arms 5, which rotate with the rotation of the rotating shaft 4, are attached to the left and right sides of the rotating shaft 4. 5 is suspended, long holes 6, 6 are opened in the longitudinal direction of the hanging arms 5, 5, and two upper and lower rods 7, 8 are arranged parallel to each other across both the long holes 6, 6 and can be raised and lowered freely. In addition to being inserted, two upper and lower rotating shafts 9 are also provided between the pillars 3 and 3.
, 10 are rotatably inserted and supported, and these rotating shafts 9, 10
A lever 11 is fixed to each of the outer ends of the levers 11 and 12, and the free ends of the levers 11 and 12 are forked parts 13 and 14, and both outer ends of the upper rod 7 are connected to the lever forked part 13 of the upper rotating shaft 9. is loosely fitted, and both outer ends of the lower rod 8 are loosely fitted to the lever bifurcated portion 14 of the lower rotating shaft 10.

A pair of front and rear support shafts 16, 17 are supported in parallel on the lower part of the upper rod 7 via brackets 15, 16, and outer shafts 18, 19 are fitted onto these support shafts 16, 17, and
Support rods 20, 21 are integrally hung downwardly at five locations in the left and right direction of these outer shafts 18, 19, and each support rod 20, 21
Food clamping fingers 22 and 23 formed by bending a metal plate into a substantially U-shaped cross section are fixed to the lower end of the frame, and the food clamping fingers 22 and 23 of the circular outer shaft 1819 are positioned opposite each other at the five locations mentioned above. There is.

Further, a tension spring 24 is interposed between the supporting rods 20, 21 of the outer shafts 18, 19 which are opposed to each other, so that the food holding fingers 22, 23 are always in the closed position. is energized by

Further, flange portions 25 and 26 are provided at the intermediate portions of the outer circular shafts 18 and 19, respectively, and fan-shaped gears 27 and 28 are formed on the opposing surfaces of these flange portions 25 and 26, so that both fan-shaped gears are always formed. By meshing the gears 27 and 28, both outer rings 1B and 19 are interlocked, and when one outer shaft 19 rotates, the other outer shaft 18 follows and rotates in the opposite direction, Brackets 29 and 30 are abutted and fixed on opposite sides of the flange portions 25 and 260, respectively, and one bracket 29 is equipped with a stopper 31 that protrudes toward the other bracket 30, and the force of the tension spring 24 is the outer shaft 18 in the direction in which the clamping fingers 22, 23 close,
When the outer shafts 19 rotate, the stopper 31 comes into contact with the bracket 30 to prevent the outer shafts 18 and 19 from rotating beyond the solid line position shown in FIG.

A portion of 30 of the brackets 29, 30 extends upward, and a roller 32 is pivotally supported at this extending end.

Another rotary shaft 33 is supported between the upper ends of the pillars 3, 3, and a spring lever 34 is provided hanging down on this rotary shaft, and the roller 32 is inserted into the rotation locus of this spring lever 34. ing.

Further, cylindrical food holding devices 35 are fixed to the lower rod 8 at five positions in the left and right direction, and these food holding devices 35 are inserted from above into the opposing food holding fingers 22 and 23.

Note that the rotating shafts 4, 9, and 1033 are rotationally driven by a cam mechanism (not shown).

In the apparatus of the present invention, the rotating shaft 4 rotates and the hanging arms 5 are swung from the tray transport conveyor 2 onto the food delivery conveyor 1 as shown in FIG. 3A.

At this time, the lever 34 is rotating and jumping over the roller 32,
The two outer shafts 16.degree. 17 are rotated by the sector gears 27, 28, and the food gripping fingers 22, 23 are opened against the tension spring 24.

Also, the levers 11 and 12 rotate upward and the upper and lower rods 7.
8 is suspended, and an elevating body consisting of elements 15 to 32.35 is rising.

From this state, the levers 11 and 12 rotate downward, and therefore the elevating bodies 15 to 32 and 35 start descending, and the open food holding fingers 22 and 23 move the food being sent on the food delivery conveyor 1. 36 as shown in Figure 3, and at the same time as this covering, the spring lever 34 that is jumping on the roller 32 moves, and the clamping fingers 22 and 23 close due to the spring force of the tension spring 24, and the food 3
Grab 6 lightly.

Next, the levers 11 and 12 move upward again, and the elevating bodies 15-
32 begins to rise, and the rotational movement of the hanging arm 5.5 is added to this, causing the food gripping fingers 22 to grip the food 36 as shown in FIG. 3C.
23 reaches directly above the tray transport conveyor 2.

A tray 37 is placed on this tray conveyor 2.

Next, the lever 11.12 moves down and the elevating bodies 15-32,3
5 descends and grips the food 36 with food gripping fingers 22°2
3 plunges into the tray 37 (FIG. 3d).

After entering, only the lever 11 moves upward, and the food holding fingers 22°2
3 starts to rise.

However, since the food restrainer 35 in the food clamping fingers 22 and 23 does not rise, the head of the food 36 is held down by the food restraint 35 as shown in FIG.
23 , the food 36 is therefore left in the tray 37 and is removed from the tray 37 by the food gripping fingers 22 .
．． 23 goes out.

Thereafter, the food suppressor 35 is also moved by the lever 12 as shown in FIG. 3i.
It rises like this.

Then, the state returns to the state shown in Fig. 3a, and the food delivery conveyor 1 is moved again.
The operation of grabbing the food 36 from above and stuffing it into the tray 37 is repeated.

Note that after filling the tray 37 with food 36, holding down the food 36 with the food holding device 35 and removing the food holding fingers 22, 23 is because the food 36 is packed in the tray 37 at relatively close intervals. This is because the food holding fingers 22 and 23 cannot be opened because there is little space between the food items 36.

The present invention has been described above, and includes a movement of a hanging arm that rotates between the upper parts of a food transfer conveyor and a tray conveyor, a movement of a pair of food holding fingers that moves up and down along the hanging arms, and a movement of a pair of food holding fingers that moves up and down along the hanging arms. By effectively combining the opening/closing movement and the interlocking movement of the food suppressor, it is possible to grasp the food on the food transfer conveyor and sequentially pack it into the trays on the tray conveyor. By mechanizing the tray filling work, it has been possible to speed up the tray filling work in response to the high speed and high efficiency of food manufacturing machines.

In particular, it is necessary to pack the food items in the tray at relatively close intervals, and therefore it is not possible to open the food gripping fingers in the tray and release the food. However, in the present invention, the food gripping fingers cannot be removed from the tray. Since the food is held down with a food restraint during the process, even if the food clamping fingers are removed without being released, the food will not follow the movement of the food clamping fingers and will remain packed in the tray. It can be packed into a tray.
