Therefore, the present invention discloses an apparatus that increases the packaging efficiency by reducing the power of the worker, and a holder made of a plurality of bar members is arranged in a horizontal and horizontal direction in front of the worker's residence space, and the holder Two parallel first rails arranged in the lower part of the holder in the direction of the open end of the holder, and a first rail arranged at the upper end of the second rail by crossing the second rail at the end of the first rail. The second lid member, the first lid and the second surface plate attached to the first lid member and the second lid member, and the holder and the first lid member along the first rail and the second rail. And a transport control means for moving the first and second surface plates between the second lid and the second lid member,
A belt conveyor for carrying meat parts into the operator's residence space, and a storage space for placing a packaging bag near the residence space,
The first surface plate and the second surface plate have lifts that move up and down in the gaps between the multiple bars that form the holder when they are carried under the holder, and are determined by signals from the foot switch by the operator. The lift provided on the board lifts the part mounted on the holder by its ascending action onto the holder, and sequentially carries it into the lower region of the first and second lids together with the wrapping bag covered on the part. It is constructed as if the part is vacuum packed inside.

  The belt conveyor carries the meat part toward the worker's residence space. An operator mounts this part on a holder made of a plurality of bar members, and puts a wrapping bag around the part from the open end of the holder. In this case, since the part is supported by the holder, the operator can quickly cover the part by opening the mouth of the bag with both hands. There is a foot switch at the operator's foot, and when the transport control device is operated with the switch, the first fixed plate that forms a pair with the first cover member is moved along the first rail and the second rail. The lift that reaches the lower area and is provided on the first fixed board enters the gap between each of the multiple bars that form the holder, lifts the part, and places the part mounted on the lift under the first lid In the pressure-resistant chamber formed by the first lid member and the first fixed plate, the part is vacuum-packed in a wrapping bag. The structure of a pressure-resistant chamber for vacuum packaging is extremely common, the surface plate is provided with a seal base, and the lid member is provided with a seal bar. When the inside of the pressure-resistant chamber reaches a vacuum value after a time of about 10 seconds, the seat bar descends toward the sealing table and seals the opening of the bag.

  During vacuum packaging work using the first lid and the first fixed plate, the operator mounts the part on a holder made of a plurality of bars, and covers the part around the part from the open end of the holder. , Operate the transport control device with the foot switch, continue the work of feeding the part wrapped in the bag with the second surface plate into the second lid, and use the two vacuum packaging devices with the heavy part It can be processed alternately.

FIG. 7 is a side view of the lifting mechanism shown in FIG. 6.

  As shown in FIG. 2, a holder 13 made up of a plurality of bar members 12 arranged in the horizontal and horizontal direction at a height of the operator's waist is arranged on the front surface of the residence space 11 of the operator 10. One end side of the bar 12 is fixed to the base 20 and the other end side is open. The belt conveyor 31 installed behind the residence space 11 has a mechanism for sequentially carrying the mounted parts 32 into the residence space.

  The operator mounts the part 32 on the belt conveyor 31 on the holder 13 as shown in FIG. 1, and removes the packaging bag 35 to be taken out from the storage location of the packaging provided near the residence space from the open end of the holder 13. Work to cover the entire surface of 32.

  On the other hand, two first rails 14 are arranged in a direction parallel to the holder 13 as shown in FIG. As shown in FIG. 3, the second rail 15 is connected to the end of the first rail 14 in an intersecting manner, and the entire rail is T-shaped in plan view.

  A first lid body 16 and a second lid member 17 that form a vacuum pressure-resistant chamber are disposed in the upper region of both end portions of the second rail 15, and each lid member has a first fixed plate 21 and A second surface plate 22 is provided. As will be described in detail later, the first fixed plate 21 reciprocates between the position of the lid 16 and the holder 13 along the rails 14 and 15 as indicated by a right-angled arrow 23, and the second platen 22 follows the rails. It reciprocates between the lid 17 and the holder 13.

  FIG. 4 shows the conveyance control means 50 for reciprocating the first surface plate and the second surface plate. That is, the main screw rod 25 is disposed between the first rails 14, and the forward / reverse motor 24 is joined to the end of the screw rod 25. A female screw 28 </ b> A having a pin 28 is screwed onto the screw rod 25, and the female screw 28 </ b> A reciprocates along the screw rod 25 as the forward / reverse motor 24 rotates.

  In addition, two sub screw rods 26 and 27 are arranged at the lower center of the second rail 15 with the main screw rod 25 interposed therebetween. Although not shown in the outer ends of these screw rods 26 and 27, a forward / reverse motor is joined, and female screws 29A and 30A having pins 29 and 30 are screwed together.

  As shown in FIG. 7, the ball 18 provided on the lower surface of each surface plate 21 engages with the groove on the upper surface of the rail 14 (15) to move the surface plate 21. That is, in FIG. 4, the main forward / reverse motor 24 rotates the screw rod 25 so that the surface plates 21 and 22 reciprocate along the first rail 14. In this case, the pin 28 selectively engages with the surface plates 21 and 22 to reciprocate the surface plates 21 and 22 via the female screw 28A. The female screws 29A and 30A also selectively engage the pins 29 and 30 with the surface plates 21 and 22, and the screw rods 26 and 27 move the surface plates 21 and 22 along the second rail 15.

  In FIG. 1, a foot switch 36 is arranged in the worker's residence space 11. Although it does not need to be a special stepping type, it is for the purpose of effectively using the feet of the worker who always uses both hands for the work, and this form can be arbitrarily changed. When the wrapping bag 35 is put around the part 32 and the foot switch 36 is operated, a signal is input to the conveyance control means 50 in FIG. 4, and the first fixed plate 21 that forms a pair with the first lid member 16 in FIG. It moves in the direction of the holder 13 along the arrow 23 and enters underneath the holder 13 as shown in FIG.

  As shown in FIG. 7, each surface plate 21, 22 is provided with a lift 43 in each gap between the plurality of bar members 12 forming the holder 13. The spring 52 provided in the cylinder 51 supported by each surface plate 21 lowers the lift 43 normally. However, when the lift 43 is inserted between the bar members 12 of the holder, the lift 43 lifts the region 32 by pushing up the cam rail 47. By lifting, the friction between the holder 13 and the part 32 is reduced, and the part 32 is mounted on the lift 43 and carried out of the holder 13.

  In FIG. 6, the screw rod 25 that transports the first and second surface plates 16 and 17 along the first rail 15 includes an encoder 48 at the tip thereof, and a forward / reverse motor from the encoder 48 via a feedback circuit 49. The amount of movement of the surface plate 16 is set by transmission to. The frame 45 installed in the lower region of the holder 13 includes a lift motor 46 that operates the cam rail 47 up and down. The feedback circuit 49 is also connected to the lift motor 46. Normally, the lift motor 46 lowers the cam rail 47, so that the lift 43 sinks into the lower region of the holder 13 together with the surface plate 16 and stops, and simultaneously with this stop, the lift motor 46 causes the cam rail 47 to move. The lift 43 lifts the part 32 from the holder 13. Subsequently, the part 32 is pulled away from the holder 13 together with the wrapping bag 35 by moving the surface plate 16 in the reverse direction.

  The length of the cam rail 47 corresponds to the length by which the lift 43 is pulled away from the holder 13. However, if the system is changed, a configuration in which the lift motor 46 is installed on the lower surface of the surface plate 16 without using the cam rail 47 and the lift 43 is directly moved up and down by the lift motor 46 can be adopted. It relates to the space for motor installation.

  In FIG. 1, a wrapping bag 35 is placed on the part 32, and the operation is started when the operator operates the foot switch 36. The first fixed board 21 sinks under the holder 13 along the right-angled rail 23, mounts a portion 32, and reverses the rail 23, and contacts the first fixed board activation switch 41 in FIG. 9. The chamber motor 48 is activated by the interference with the activation switch 41, and the first lid member 16 is lowered via the rack 49 to seal the portion 32 with the first fixed plate 21.

  The seal stand 60 provided on the first fixed plate 21 supports the bag mouth from below. The hose 54 is for sucking air in the lid member 16, and the actuator 53 is a device that presses the seal bar 55 against the seal base 60 and seals the bag mouth of the wrapping bag.

  In order to vacuum wrap this type of part, an operation time of 10 seconds or more is required. When the operation is completed, the external power removes the vacuum packaged product on the surface plate from the surface plate. Meanwhile, as shown in FIG. 5, the worker 10 continues the work of mounting the subsequent portion 32 on the holder 13 and covering the packaging bag 35, and operates the foot switch 36 following the completion of the work. In FIG. 1, the second surface plate 22 carries a part along the rail 37 into the second lid member 17 and operates the start switch 42. The vacuum packaging operation performed by the interference with the activation switch 42 is as already described in paragraph 0023.

  In FIG. 8, the belt conveyor 70 is protruded from the base 20 to the upper part of the holder 13, and the belt conveyor 70 protruding from the upper surface of the holder is retracted in the direction of the arrow 71 so that the portion 32 is placed on the holder. It has the effect of reducing the labor force of workers.
