A chain 25 is wound around a sprocket 23 of a nine-speed variable speed motor 22 and a sprocket 24 serving as a transmission wheel, which are arranged at the bottom of the workbench 17, and a chain 25m is also wound between the sprocket 24 and the sprocket 20. It's a rotation. Therefore, the packet conveyor 18 is driven in the direction of the arrow by the drive of the motor 22 via the chain 25.25m. The conveyor chain 21 also has a plurality of (four in the drawings) packets 26, which is a feature of the present invention.
27, 28, and 29 are attached at regular intervals.

Now, the specific structure of this packet will be explained based on FIGS. 4 to 6. Kao, each packet 26゜27.2g
, j29 are all the same, so only the packet 26 will be explained, and the explanation of the relaxed Ω packet will be omitted.

The packet 26 is composed of a plurality of nine narrow plates 30 arranged in series along the moving direction of the conveyor chain 21. Standing portions 31 and 31 are formed at both ends of each plate, and side plates jj and 32 are provided only on the front and rear plates 30m and 30b, and the whole is a box with one opening between the upper ends. It is.

The size and depth of the bag are determined so that the product G can be stored in the packet 26, and the product G can be moved against the rocking of the ship at sea and can be moved out of the packet.
The height of the side plate 32) is preset. Each plate 30 of the packet 26 is attached to the conveyor chain 21 by suitable attachment means such as bolts and nuts, and is flexible like this chain. In addition, packet 2
A microswitch suppressing part (not shown) is attached to the bottom of the workbench 6, and this pressing part can suppress the microswitch attached to the workbench 17. This suppression allows the shibake soto 26 (packet conveyor 18) to stop at a predetermined position.

In Figures 1 and 2, a top seal section 33 is provided on the rear end side of the packet conveyor 18 in close proximity to the film rollers 12, 12m. This top seal section consists of a top seal rubber base 34 and a top seal heater section 35. The rubber stand 34 is mounted on the rear end of the workbench 17, and its upper surface is the same as the upper surface of the support stand 1. The heater part 35 is provided above the rubber stand 34 and facing each other.
It is fixed to the lower end of a ram 40 of a cylinder 39 that is vertically installed at the rear end of B. The heater section 35 is moved up and down by the operation of the cylinder P9, thereby sealing the front and back of the product G whose upper and lower sides are covered with the film F, and cutting the film.

In general, side seal portions 41 and 41 are provided facing each other on both sides of the packet conveyor 18 from the center to the front portion thereof. To explain one side seal part 41, a side seal heater part 42 faces above a side seal rubber base (not shown) provided on the workbench 17,
The heater section is attached to the base 43. This base is connected to the ram 45 of the cylinder 44 which is vertically mounted on the frame 38.
The arm 47°4-7 is fixed to the lower end of the support frame 46.
It is held through. Guides 48, 48 are provided at both ends of the support frame 46, allowing the guide columns 37, 37 to be moved up and down. The heater section 42 is movable up and down along the guide columns 37 and 37 by the operation of the cylinder 44, and thereby seals the sides of the product G whose front and rear sides have been sealed by thermocompression bonding.

The configuration of the other side seal portion 41 & is also substantially the same as that of the side seal portion 41 described above, and constituent parts corresponding to this side seal portion are given the same reference numerals.

Further, at the rear end of the workbench 17, a push rod 49 is installed along the top seal rubber base 34 in FIGS. 1 to 3. Both ends of the push rod 49 are connected and supported via levers 50, 50 to a shaft 51 which is rotatably supported at both ends on the workbench 17. The shaft 51 is connected via a connecting member 54 to the tip of a ram 53 of a cylinder 52 attached to one side of the workbench 17. Therefore, cylinder 5
Due to the expansion and contraction of the ram 53 of 2, the push rod 49 is attached to the shaft 5.
1, and sends the product G, which is sealed at the front and back, to the packet conveyor 18. At the frontmost side of the conveyor 18, as shown in FIGS. 1 and 2, a pushing rod 55 is installed for pushing out the product G, which has been packaged on all sides, front and back, and on both sides, to the packaging line. The operating mechanism of the push rod 55 is substantially the same as that of the push rod 49'.

56 is an extrusion lever, 57 is a shaft, and 58 is a connecting member.

59 is a cylinder, and 60 is a ram. The push rod 55 is swingable about the shaft 57 by the operation of the cylinder 59.

Next, the operation will be explained.

As shown in FIG. 1, the products G are sequentially conveyed forward by the conveyors 2 and 3, and eventually the product G located at the forefront is placed on the extrusion plate 6, and this product is carried by the following products G. Since it is being pushed out, it hits the stopper 10. At this time, in order to block the light emitted from the phototube 11 by the product 1, the push-out plate 6 is detected to be in contact with the belt portion 3.
m', give patronage up to 3b. As a result, the product G falls onto the support stand 1 and is located in front of the extrusion plate 6, as shown in FIG. After that, the extrusion plate 6 moves forward and pushes out the product G toward the top seal part 33, and as a result, the product moves forward while rolling in the film F, which is a sheet, as shown in FIG. 8, and the right end of the product When reaching the left side of the top seal part (heater part 35) as shown by the solid line in Fig. 9,
Stop the forward movement of the extruded plate.

As a result, both the upper and lower sides of the product G are covered with the film F. and product G1 is located in packet 26 (first
(Illustrated with chain lines). Therefore, this time, the extrusion plate 6 is retreated,
When the extrusion plate 6 returns to a position where it would be dangerous to operate the seal part 35, the heater part 35 descends as shown by the chain line in FIG. 9, and the product G is completely covered by the film F. The film on the rear end side is held between the heater section 35 and the fifth heater stand 34, and the heater is activated to start sealing by thermocompression bonding. This sticker is displayed after the time set in the timer elapses. At the same time as the end, the heater section 35
rises. By the operation of this heater section, the film F on the rear end side of the product GI is press-sealed and simultaneously cut. As a result, the product Gl is wrapped in a film with the front and back sealed, as shown in FIG. 10.11. When the heater part 35 finishes sealing and rises, the push rod 49 swings counterclockwise around the shaft 51 due to the operation of the cylinder 52, pushing the product G toward the side seal part 41.41a, and this pushing out At the same time,
The packet conveyor 18 moves in the direction of the arrow while holding the product G in the packet 26. When the ram 52 of the cylinder 51 is extended to its maximum stroke, the ram starts to contract again and stops pushing out the booster rod 49, and at the same time the packet conveyor 18 also stops and the next product G is pushed into the packet 29. Watch. The stop position of the packet 26 corresponds to the side seal portion 41.41m.

Then, when the next product am (Fig. 1) is placed on the extrusion plate 6 and is pushed out by the subsequent product and hits the stopper 10,
The extrusion plate retreats again, and the product falls onto the support stand 1.
The extrusion plate 6 extrudes the product forward, and stops extrusion when the product is extruded to the left of the top seal portion 33. Therefore, the operation of the top seal portion 33 and the side seal portions 41 and 41m is started simultaneously. The operating time of each seal section is controlled by a timer. To explain the operation of the side seal portion 41.41m, cylinder 4
The ram 45.45 of 4.44 is extended and the heater part 42.4
2 is lowered and positioned at both ends of the film F covering the product as shown by the dashed line in FIG. 11, where the heaters are activated to seal these ends. As a result, the product GI is sealed on all four sides, front and back, and on both sides, and is completely hermetically packaged with the film F.

When the top seal unit 33 finishes sealing the product G, the packet conveyor 18 starts and the packet 26
The product GI is sent to the product accumulation section by the pushing rod 55, and the product G1 held in the packet 29 is moved to the side seal section 41.41m. Thereafter, when the third product is pushed out to the packet 28 by the extrusion plate 6, product G is wrapped in film at the shield seal section 41° 41m, and the subsequent products are film wrapped at the top seal section 33 in the same manner as described above. Thereafter, the product G is conveyed by the conveyor 18, and the subsequent products are delivered to the side seal section 41.
．． Move to 41m. In this way, extrusion of the product, front and back and lateral sealing, and transportation are repeated.

The products conveyed by conveyor 1B are packets 26 to 2.
9, the position is reliably held, so there is no problem with the rocking of the ship at sea.

Note that the packet conveyor 18 may be started when the product comes into contact with the stopper 10. In addition, the product G conveyed by the conveyors 2 and 3 is placed on the extrusion plate 6, and the extrusion plate retreats due to the contact of the stopper, and the product that has fallen in front of the extrusion plate is transferred to the workbench 17 side by the extrusion plate. If the configuration is adopted, the subsequent product will be placed on the extrusion plate while the product is being extruded, so the extrusion plate can be extruded continuously, making the extrusion work more efficient and faster. can be achieved. However, the configuration is not limited to this, and the product may be conveyed by a conveyor in front of the extrusion plate. Furthermore, the packets according to the present invention are not limited to those related to packaging devices.

As explained above, according to the present invention, 1. It is a box with multiple plates and an opening at the top, and it is flexible like a conveyor chain, so it can reliably hold the product in the packet against the rocking of a ship at sea, thus ensuring that it is in the correct position. The machine can be set and other necessary work such as packaging can be carried out on the conveyor.
