Substantially U-shaped support frames 30c and 30d are attached to the upper surfaces of the slide frames 17c and 17d, respectively, so as to be tiltable toward the inside of the apparatus main body A. Here, hydraulic cylinders 21c and 21d are respectively interposed between the slide frame 17c and the support frame 30c and between the slide frame 17d and the support frame 30d. By extending the hydraulic cylinders 21c and 21d, Support frame 30
The c and 30d can be tilted toward the inside of the apparatus main body A (see FIG. 6). As shown in FIGS. 1, 2 and 7, the main body frame 20 is provided between the upper portion of the support frame 30a and the upper portion of the support frame 30c and between the upper portion of the support frame 30b and the upper portion of the support frame 30d.
a and 20b are installed. Body frame 20a, 2
0b has take-ups 7a and 7b at the front thereof, respectively.
Are fixed, and sprockets 32, 32 are pivotally attached to the take-ups 7a, 7b, respectively. The conveyor chains 2 and 2 are stretched between the sprockets 32 and 32 and the drive sprockets 12 and 12.
The rotation of the adjusting bolts 33 of the take-ups 7a and 7b allows the tension to be adjusted. A plurality of pins 3 projecting outward are attached to the conveyor chain 2 at equal intervals, and the sealing bag is transported to the rear of the apparatus main body A in a state of being pierced by the pins 3. The body frames 20a and 20b are provided with hinges 5a and 5b, respectively, which are rotatably pivotally supported near the front portions thereof, and presser wheels 4a and 4b are attached to the tips of the hinges 5a and 5b. It is rotatably attached. The body frame 20a (2
0b) is provided with two stoppers 34, 35 with the base end of the hinge 5a (5b) sandwiched therebetween, whereby the hinge 5a (5b) is tilted forward by about 30 ° from the vertical state. It is designed to be tiltable between states. Here, the hinge 5a (5b) is the spring 6a.
(6b) always urges the front of the apparatus main body A, whereby the hinge 5a (5b) is normally held at a position inclined forward by about 30 °. For this reason, the sealing bag is transferred from the front of the apparatus main body A to the conveyor chain 2,
When it is sent to 2, the bag is pressed down by the presser wheels 4a and 4b attached to the tips of the hinges 5a and 5b, so that the bag can be easily pierced into the pin 3. As shown in FIGS. 2, 3, and 7, the base frame 16a located at the front part of the apparatus main body A is provided with a support rod 37 at a substantially central portion thereof, and an upper end of the support rod 37. A rotary blade 22 that is rotated by a motor 38 is attached to the. As a result, the lower surface of the bag is incised at the first stage of transfer by the conveyor chains 2 and 2. Here, the rotary blade 22 jacks the support rod 37 into the jack 23.
It can be positioned at an appropriate height by expanding and contracting. Figure 1, Figure 2, Figure 4,
As shown in FIG. 7, the main body frames 20a, 20b are provided with hitting frames 25a, 2b at approximately the center thereof.
5b is attached. Then, the beating frame 25a (25b) has a large sprocket 8 at the lower portion thereof.
a (8b) is pivotally supported, and a small sprocket 9a is provided on the upper part.
(9b) is pivotally supported. Here, large sprocket 8
The a (8b) is linked with the conveyor chain 2, and the large sprocket 8a (8b) and the small sprocket 9a (9b) are connected via the chain 10a (10b). The shaft 36a (36b) of the small sprocket 9a (9b) is provided so as to extend inside the apparatus main body A, and a plurality of rubber taps 11a (11b) are attached to the shaft 36a (36b). There is. Therefore, the hits 11a and 11b rotate in the same direction in conjunction with the conveyor chains 2 and 2, so that the bag can be hit by the hits 11a and 11b during the transfer to assist the work of discharging the contents. Here, a piano wire is embedded in the hits 11a and 11b so that the hits 11a and 11b have a certain strength. Figure 1, Figure 2,
As shown in FIGS. 5 and 7, the rear part of the apparatus main body A is
An enclosing bag removing cover 15 is attached to sandwich the conveyor chain 2 and tilt upward toward the rear. Therefore, when the bag is transferred to the rear part of the apparatus main body A, the bag rides on the bag removing cover 15, and the bag can be removed from the pin 3. Here, the envelope removing cover 15 is
It also functions as a protective member for a drive unit such as the drive sprocket 12.

Next, the operation of the incision device constructed as above will be described. The apparatus main body A is used, for example, installed on a truck bed or the like. After being installed on the loading platform of the truck in this way, first, the motor 13 is driven to rotate the drive sprocket 12 via the speed reducer 14 (arrow A). As a result, the conveyor chain 2 starts to rotate clockwise (arrow B), and the hits 11a and 11b also rotate in the same direction (arrow C) in conjunction with the rotation of the conveyor chain 2. Next, when the motor 38 is driven, the rotary blade 22 starts rotating. In this state, when the sealing bag 40 is fed in from the front part of the apparatus main body A, the sealing bag 40 firstly receives the presser wheel 4
It is pressed down by a and 4b and pierces the pin 3 on the conveyor chains 2 and 2. The sealing bag 40 is transferred as it is to the rear of the apparatus main body A by the conveyor chains 2 and 2. Then, the sealing bag 40 is provided with the cutting blade 2 during the transfer.
It is incised by 2, and the contents of the sealing bag 40 begin to be discharged. After the opening of the bag 40, the bag 40 is struck by the hits 11a and 11b arranged in the substantially central portion of the apparatus main body A to assist the work of discharging the contents. Incidentally, as shown in FIG.
If the conveyor chains 2 and 2 are tilted inward toward each other and the rotary blade 22 is lowered,
The contents existing in the corner of the sealing bag 40 can be completely discharged. The sealed bag 40 whose contents are discharged is the device main body A.
The bag 40 is transferred while climbing over the bag removing covers 15 and 15 provided at the rear part of the bag, whereby the bag 40 is removed from the pin 3. With the above, the cutting and discharging work of the sealing bag 40 is completed.

[0008]

As described above, according to the present invention, a device for automatically incising and discharging a sealing bag is provided on both sides of the main body of the apparatus, and a pair of endlessly connected rotary transfer members connected to each other, and the rotary transfer. A plurality of pins protruding from the outer surface of the body,
It is located between the presser wheel provided above the pair of rotary transfer bodies and near the front ends thereof to pierce the pin with the sealing bag and the pair of rotary transfer bodies, and near the front ends of the rotary transfer bodies. Since the rotary blade is provided and the bag removing cover is provided at the rear end of the rotary transfer member near the rear end and is inclined upward toward the rear, the bag can be cut efficiently. Since the contents of the sealing bag can be automatically discharged, there is an excellent effect that the labor in cutting and discharging the sealing bag can be reduced.
