Description

  The present invention relates to a method and an apparatus for automatically selecting a packaging bag adapted to the size of a part of livestock meat (hereinafter simply referred to as a part) that has been disassembled and packaging the part.

  Dismantled slaughtered meat was once shipped to the market with bone attached, but in recent years, after removing the bone and greasing, it is further cut and divided to increase the shelf life. There is a distribution in which the products are packaged in a bag and then shipped after vacuum packaging. As one of such forms, in Patent Document 1 below, the bag mouth of the packaging bag is adsorbed with a vacuum cup and opened upward, and the portion is pushed into the packaging bag from the opening portion with a carry-in conveyor However, there is a problem that it is uneconomical because a bag of the same area is used even though there is a volume difference of about 50 cm or more for a large part and about half of that for a small part.

  On the other hand, in Patent Document 2 below, a bag filling device for filling a part into a bag with a push-in bar and then pushing the part and the bag into the vacuum packaging machine with the push-in bar, and the vacuum packaging Disclosed is a technique for removing slack in the bag mouth by tensioning the bag mouth of the wrapping bag on both sides with a pair of spatula plates in the machine. However, even if the cut portion is cut, the beef is a large chunk of more than 30 kg, so the bag mouth of the wrapping bag that accommodates such a portion is immediately after the tension due to the spatula plate is removed. Since a large slack occurs again, before pulling out the spatula plate from the bag mouth, the bag mouth has to be fixed to the sealing base with a separate clamp, and in this respect, there is a problem that a reduction in work efficiency is inevitable. There is.

  In Patent Document 3 below, each part that conveys the conveyor line in tandem is classified into a plurality of types by a measurement sensor, and the classification electronic data is recorded by a controller. In the pressure-resistant chamber for vacuum packaging arranged in each of these branch lines, the above-mentioned branched parts are packaged and vacuum packaged. There is a problem that wrinkles are likely to occur in the opening, and there is a problem that the speed is reduced because the traveling direction of each part is selected in the conveyor line.

  Since a general rotary vacuum packaging machine has the ability to process 40 or more parts contained in a sachet per minute, in order to perform efficient part packaging that does not waste this processing capacity, According to the invention, the size of each part conveyed in tandem along the conveyor line is measured by a measurement sensor, and each part is classified into a plurality of groups, and on the basis of the sorted electronic data recorded in the controller, the conveyor A plurality of bag loading units of different sizes arranged in a state intersecting with the line are moved so that the bag loading unit of the size selected by the sorted electronic recording data is the same as the preceding carry-in mechanism in the conveyor line. Set between the rear carry-out conveyor and open the opening of the bag in the set bag stacking unit with a movable suction cup installed in the upper area. On the other hand, the carry-out conveyor protrudes from the lower part of the wrapping bag, and the part mounted on the carry-in mechanism and stopped at a specified position is divided by a push-out movement of the carry-in mechanism itself and a feed-out movement by the carry-in mechanism. While being pushed into the wrapping bag, the portion is further transferred to the carry-out conveyor, and then the portion is transferred by the rotation of the carry-out conveyor, and the wrapping bag is calculated from the size data of the wrapping bag covering the portion. The movement of the opening edge is monitored, and the opening edge is clamped by the sealing stand and a seal bar approaching the sealing edge in accordance with the timing when the opening edge passes over the sealing stand provided on the carry-out conveyor, With the two sealers that move synchronously with the rotation of the carry-out conveyor, the packaging bag with the pointed seal at the opening edge is carried out toward the vacuum packaging machine.

According to the above configuration, the size of each part transported in tandem is measured by a measurement sensor and sorted into a plurality of groups, and the size of the part is automatically selected by a bag loading unit having a size corresponding to this sorted electronic recording data signal. The economy can be improved by selecting a suitable bag.
In addition, the movement of the opening edge of the packaging bag calculated from the size data of the packaging bag is monitored, and the timing at which the opening edge passes over the sealing table provided on the carry-out conveyor is calculated. The opening edge is clamped with a stand and a seal bar approaching the base, and the opening edge is point-sealed with the two sealers that move in synchronization with the rotation of the carry-out conveyor. In other words, point sealing is not performed when the bag is stopped, but the bag can be point-sealed while the part is being transported. It is also efficient in that the process can be omitted.

  Crossing the conveyor line of the site | part 10 shown by a plane in FIG. 1, the horizontal four bag loading unit 30 which accommodated the bag which each differs in size is arrange | positioned, and this bag loading unit 30 is separated and front The carry-in mechanism 20 composed of a belt conveyor in the area and the carry-out conveyor 40 in the rear area are installed in series. Note that the foremost conveyor 80 in the conveyance direction of the part includes a measurement sensor 82 that measures the size of the part 10 to be conveyed, and the measurement record is input to the controller 83 and is a signal emitted from the controller 83. Various motors will be controlled, details of which will be described later.

  As shown in FIG. 3, each of the four horizontal bag stacking units 30 described above has the power of the motor 11 inchingly rotates the belt conveyor 12, the take-up shaft 13, and the reel shaft 14, and is placed on the carriage 15. It is the structure which pulls out continuously the continuous packaging bag 17 arrange | positioned in the corrugated cardboard paper box 16 folded up in a zigzag manner.

  As shown in FIG. 4, the wrapping bag is formed by attaching the opening edges of a large number of wrapping bags 17 to the armor stack by shifting about 50 mm each on two pressure-sensitive adhesive tapes 18. The bag loading unit 30 showing a flat surface is pulled intermittently by 50 mm each of the two pressure-sensitive adhesive tapes 18 so that the end of the most advanced bag 17 is connected to the end of the belt conveyor 12 and the idler 19. When the leading edge packaging bag is peeled off from the tape 18 by pulling out to the vacuum adsorbing type fixing element 21 in between, each subsequent packaging bag is sequentially pulled out by 50 mm.

  FIG. 6 is an enlarged side view of the belt conveyor which is the carry-in mechanism 20 in FIG. 1. A flat belt 26 is supported on a frame 24 which is slidably supported with respect to the conveyor guide 23 via a plurality of pulleys 25, and a motor. The belt 26 is rotated by a main pulley 28 having a power source 27 as a power source. A pulse motor 31 is installed as a power source for a chain 29 that reciprocates the frame 24 along the conveyor guide 23.

  In the same FIG. 6, the part 10 fed from the front belt conveyor 41 to the upper surface of the carry-in mechanism 20 is stopped at a predetermined position by the stepwise deceleration of the belt 26 by touching the infrared rays of the pair of sensors 42. Although the timing of carrying out back is measured, the carrying-in mechanism 20 follows the conveyor guide 23 toward the packaging bag by opening a packaging bag (not shown) at a position facing the carrying-in mechanism 20. It sticks out.

  In the same figure, the upper guide rail 32 of the carry-in mechanism 20 supports a pair of bag mouth tension members 34 via a frame 33. As shown in FIG. 7, which is a plan view, the pair of pins 35 fixed to the horizontally long frame 33 are supported by the pair of bag mouth tension members 34 having bending characteristics, and both the bag mouth tension members are supported. 34 is connected so as to be openable and closable by rotation of a pair of meshing fan-shaped gears 36, and a pneumatic cylinder 37 fixed to the frame and the both gears 36 are connected via a V-shaped link 38.

  In the bag loading unit 30 of FIG. 3, the upper movable sucker 43 of the element 21 that adsorbs and fixes the bag mouth of the packaging bag 17 from below is adsorbed to the lower packaging bag and opens the packaging bag. The edge opens upward, and a specific diagram thereof will be described below.

  That is, as shown in the front view of FIG. 8, the lifting / lowering material 48 is attached to the plate frame 45 fixed to the suspension column 44 in the upper region thereof via a plurality of pulleys 46, 47 at the arrangement position of the bag loading unit 30. The movable suction cup 43 is formed by a plurality of vacuum cups on the lower surface of the horizontally long bar 49 supported in the standing direction and fixed to the lower end of the elevating member. On the other hand, the pinion 51 provided in the pulse motor 50 for opening the bag mouth fixed to the plate frame 45 is engaged with the rack 52 on the side surface of the elevating material and sent through the circuit 54 provided between the controller 53 and the separation recording of the part From the data, the amount of movement of the movable suction cup 43 is controlled to set the opening width of the bag 17 according to the size of the portion to be filled.

  FIG. 9 shows an enlarged side surface of the carry-out conveyor 40 in FIG. 1. A pulse motor 56 for rotating the carry-out belt is installed in the frame-type conveyor frame 55, and a driving pulley 57 supported by the motor and other pulleys at both ends. While the conveyor belt 55 is supported by 58 and 59, the conveyor frame 55 is slidably supported by angle-type horizontal guides 61 on both sides, and the movement of the conveyor frame 55 relative to the horizontal guide 61 is performed by the motor 100 of FIG. Do.

  In FIG. 10, which is a plane, the suspension pillar 63 fixes the horizontal guides 61 on both sides, and the frame type conveyor frame 55 is slidable along the upper surface of the horizontal guide 61. The belt of the carry-out conveyor 40 includes a plurality of string belts, and the conveyor frame 55 is reciprocated in a certain region of the horizontal guide 61 by the power of the motor. In this case, the seal base 64 formed on the frame type conveyor frame 55 also reciprocates together.

  As shown in FIG. 11, both ends of the seal bar 65 disposed in the upper region of the seal base 64 are connected to the piston rods 67 of the fluid cylinders 66 erected on both sides of the conveyor frame 55. A temporary sealer is formed by the intermittent projection 79. The seal bar 65 has a pipe heater 78 for heating inside. The seal bar 65 can be moved downward toward the lower seal base 64 by the motor power of the fluid cylinder 66, and discontinuous point sealing can be performed on the wrapping bag with the clamping pressure by the projection 79.

  An enlargement of the foremost conveyor 80 in FIG. 1 is illustrated in FIG. That is, when the part 10 is transported in a tandem shape along the side wall 81 in the conveyor 80, the photoelectric measurement sensor 82 installed in the passage area of the part is irradiated with a large number of infrared rays irradiated from the side surface and the top surface. Therefore, the length of the part 10 is measured from the cross-sectional area of each part 10 passing through and the passage time of the part 10, and the detection signal is input to the controller 83 as electronic record information. Sometimes a camera is used.

  In this case, as shown in FIG. 16, the cross-section of the site 10 where the bone has been removed generally has a relation that the measured value of the width (A) is <1> and the height (B) is about <0.5 to 0.8>. It is. Therefore, the arithmetic unit in the controller 83 divides each part from the measurement data as shown in FIG. 28, for example, the horizontal width value, for example, 40 to 25 cm is large (A), and for example, 25 cm or less is small (B). Record separately. For example, if the length of the part is increased to 70 to 50 cm and the length of 50 to 30 cm is reduced, the width (A) of 40 cm, the length of 70 to 50 cm is classified as A1, and the width (A) of 40 cm. According to this, those having a height of 50 to 30 cm are classified as A2, and those having a height of B are also classified as B1 and B2. An unmeasured boundary 200 having a length of, for example, about 2 cm is formed between the four types of parts. In other words, by installing this non-measurement boundary 200, it is possible to mechanically exclude parts having values along the non-measurement boundary from the conveyor line, and to reliably classify each part as A1, A2, B1, B2. Become. However, due to the above-described exclusion, the transport order of the parts 10 that transport the conveyor line in FIG. 1 is different from the electronic information recorded by the controller 83. For example, an auxiliary measurement sensor is installed on the conveyor 41, The classification information of each passing part 10 is recorded in the controller 83 anew. Therefore, the “measurement sensor” described in the claims includes this auxiliary measurement sensor.

  On the other hand, the electronic and data recorded by the controller is transmitted as a command signal to the lower motor 85 in FIG. 3 in the recording order so that the pinion 86 fixed to the shaft of the motor is connected via the rack teeth 87. The carriage 15 is moved along the rail 89, and the selected bag loading unit 30 having a size corresponding to the portion to be conveyed is set in the conveyance area of the portion from the parallel bag loading units 30. In short, the four bag stacking units 30 having different size bags in FIG. 1 are moved with the electronic recording data of the controller 83 and correspond to the unit of the size of the part 10 that has reached the carry-in conveyor 20. The bag is carried out between the carry-in conveyor 20 and the carry-out conveyor 40. By such an action, the sachets corresponding to the sizes of the parts 10 to be transported are sequentially opened, and the corresponding parts can be carried into the sachets.

  In FIG. 8, the momentum of the movable suction cup 43 that opens the wrapping bag 17 is moved upward and opened in the case of the wrapping bag 17 having a larger lateral width compared to the wrapping bag having a smaller lateral width. In short, in FIG. 16, the relationship between the average lateral width A and the height B of the portion 10 has already been explained, but the movable suction cup moves to a level that satisfies the relationship with the height B of the portion to be wrapped, Open the bag.

  Therefore, in the bag loading unit 30 in FIG. 12, when the state-of-the-art packaging bag 17 is pulled out with the tape 18, and the lower surface of the bag mouth adsorbs to the fixing element 21 by the vacuum suction force, it descends from the upper region. The movable suction cup 43 adsorbs and pulls up the upper surface of the wrapping bag 17 and opens, and at the same time, the insertion of the bag-tensioning material 34 into the wrapping bag 17 is started, while it is fixed to the frame that supports the suction cup 43. The blown air pressure from the fan 68 inflates the sachet 17 to form a three-dimensional shape.

  Subsequently, as shown in FIG. 13, the fixing member 21 and the fixed suction cup are pressed against the bottom surface of the wrapping bag 17 by pushing the portion 10 against the bottom surface of the wrapping bag 17 with the protruding momentum of the loading mechanism 20 mounting the portion 10. The wrapping bag 17 is taken from 43 and the wrapping bag 17 is further moved forward to transfer the portion 10 to the carry-out conveyor 40. In this case, the controller determines the ejection momentum of the carry-in mechanism 20 and the delivery momentum due to the rotation of the belt 26 based on the recorded size of the packaging bag 17 and the fractional value of the portion 10. As described above, after the part 10 is transferred to the carry-out conveyor 40, the carry-in mechanism 20 returns to the original fixed position. On the other hand, the carry-out conveyor 40 that has received the transfer of the part inherits the conveyance of the bag 17 by its rotation.

  In FIG. 9, the movement of the opening edge of the packaging bag calculated from the size data of the packaging bag 17 is monitored. Starting in the direction of the arrow 60, the seal bar 65 is lowered toward the seal base 64 at the same time, the opening edge is clamped by these temporary sealers 70, and as shown in FIG. Is given.

  This movement control will be described with reference to FIG. The front end of the belt conveyor 26 constituting the carry-in mechanism 20 normally stops at a stopping point 71. However, when the conveyor carries the part 10 and advances into the packaging bag 17, the packaging bag 17 used from the classification record data of the part 10 Therefore, the bell and 26 are plunged to the advance point 72 based on the size data of the wrapping bag 17, and then the portion 10 is pushed to the carry-in point 73 by the rotation of the belt 26. As a result, the bag mouth of the bag 17 existing at the base point 74 is detached from the suction cup 65 and transferred to the carry-out conveyor 40. With the subsequent rotation of the carry-out conveyor 40, immediately before the bag mouth passes over the seal point 75 in FIG. 9, the frame frame 55 starts to retract, and the seal bar descends from the top to the seal base 64 to point-seal the bag mouth. Is carried out.

After that, the carry-out conveyor 40 continues to rotate, and the package is sent to the rotary vacuum packaging machine in the rear region, and sealed inside the point seal 76 applied to the bag 17 in the pressure-resistant chamber as shown in FIG. The seal 80 is completed. In this case, since the film mouth is increased in film rigidity by the point seal 76 applied in advance, it is not necessary to fix the bag mouth with a clamp when the bag mouth is hermetically sealed in the vacuum packaging machine. After that, the seal base 64 and the seal bar 65 that performs the block motion are returned to the original fixed positions in order to receive the packaging bag that accommodates the subsequent portion.

  The most time-consuming work in the conveyor line is that the suction cup 43 in FIG. 12 pulls up the bag mouth of the bag 17 and opens it, and simultaneously with the insertion of the bag mouth tendon 34 into the bag mouth, the carrying mechanism 20 as shown in FIG. This is a movement from pushing the part 10 into the wrapping bag 17 and peeling the wrapping bag from the fixing element 21 until the transfer of the wrapping bag 17 is inherited by the rotation of the carry-out conveyor 40. As a result, it is possible to pack the bag in about 2.5 seconds to about 3 seconds.

  In this case, the most concerned is the mistake of sucking the movable suction cup 43 in FIG. On average, such a phenomenon is obtained that occurs at a frequency of about 1% per number of wrapped bags. Therefore, a vacuum gage 88 is installed in the line 84 connecting the horizontally long bar 49 and the vacuum pump, and air inflow occurs from the movable suction cup 21 due to a mistake in adsorption to the bag, and the measured value of the line 84 by the vacuum gauge 88 reaches the set value. When not, the controller 53 issues a signal to lower the horizontally long bar 49 again, and controls the vacuum sucker 43 to try to suck the bag 17 again.

  That is, the “OK” symbol in step P1 in FIG. 22 corresponds to an electronic signal notifying that the selected packaging bag 17 has been moved to the set position, and corresponding to this signal, the movable sucker 43 is instructed as in step P2. A descent command to the bag is issued. Immediately after this, after the vacuum action to the movable suction cup 43 is achieved in step P3, a command to raise the movable suction cup 43 in step P4 and a vacuum measurement of the suction cup 43 in step P5 are instructed. If the vacuum measurement value is normal in the discrimination in step P6, a part carry-in command is issued by the carry-in conveyor 20 in the open bag as in step P7, but if the vacuum measurement value is abnormal, In step P8, the standby command for the carry-in conveyor 20 is issued, while the movable suction cup 43 is urged to be sucked by the lowering of the movable suction cup 43 in step P9, and the movable suction cup 43 is raised again in step P4. The opening of this is intended.

  In addition, there is a possibility that the part to be pushed into the wrapping bag will be caught in the bag mouth of the wrapping bag with the same percentage as the mistake, and this may cause a mistake in carrying the part into the wrapping bag. Is done as follows.

  That is, in FIG. 8, when the movable suction cup 43 sucks into the bag 17 and the measured value of the vacuum gauge 88 increases, the signal 130 is input to the controller 53, and at the same time, the controller 53 sends a signal to the relay 131. Since the switch 132 is closed, the integration of the timer 133 is started. Reference numeral 130 in FIG. 23 indicates that the vacuum value of the movable suction cup sucked on the packaging bag to open the packaging bag has reached the set value and the signal is transmitted from the vacuum gauge to the controller. P10 indicates that the signal 130 prompts the timer to start integration. With this start signal, integration is started as shown in step P11, and the integration time is measured at the same time. Meanwhile, the measured value with the vacuum gauge in step P12 is monitored.

  In FIG. 24, symbol C indicates a cycle of the packaging operation, and one cycle C includes a vacuum time V in which the sucker sucks the wrapping bag and a time Z in which the wrapping bag is separated from the sucker. During the time calculation shown in step P11, if the measured value at the vacuum gauge at step P12 is kept at a high level, the operation proceeds as in the prescribed program as in step P13, but the part to be carried in is temporarily covered. When the bag is forcibly peeled off from the sucker sucking and sucking the bag, the vacuum gauge 88 will sense the air pressure until the set time V of the timer is completed, so control as described in step P14 As a result of sending a signal for placing the corresponding part incompletely packaged on the recycle line, the part is removed from the rear of the carry-out conveyor 40 in FIG. 2 in the front region, it become possible to recycle the conveyor line.

  In FIG. 1, each wrapping bag having a different length accommodated in the four bag stacking units 30 is arranged so that the respective bag mouths are arranged in a line, and therefore the carrying mechanism 20 is moved back and forth. The rotation angle of each of the motor 31 for advancing and the motor 28 for rotating the belt conveyor 26 of the mechanism 20 is controlled to control the amount of insertion of the carry-in mechanism 20 into the bag and the amount of push-out of the bag. There is a need. That is, if this adjustment is not performed accurately, the seal bar 65 in FIG. 9 cannot be accurately lowered to the mouth edge of the moving bag 17.

  In the packaging of the site, the length of the wrapping bag 17 in FIG. 2 is large and exceeds 80 cm, and may be half that of the small wrapping bag. Since the position changes and the push-out amount of the carry-out conveyor 40 changes at the same time, the relative approaching amount of the two conveyors 20 and 40 is adjusted by the rotation angles of the motors 31 and 56 in FIG. To do.

  The carry-out conveyor 40 in FIG. 10 is formed by using parallel string belts, and the sealer is lowered from above on the sealing base 64 having stepping stone-like projections arranged between these string belts, thereby opening the packaging bag. Although it has been described that the edge is point-sealed, the strap belt 40 is formed by a flat belt, and the tooth-shaped protrusion 79 on the lower surface of the sealer 65 shown in FIG. In the process of clamping and retracting the flat belt 40 and the seal base 64 together, the bag mouth can be spot-sealed.

  The bag loading unit 30 in FIG. 3 has a configuration in which the packaging bag 17 affixed to the tape 18 is pulled out by winding the tape 18, but the bag loading unit 91 in FIG. The height level of the wrapped bag 17 is monitored by a sensor 93, and the board 92 is raised and raised through rack teeth 95 that mesh with the pinion 94 so that the upper surface of the wrapped bag 17 is always kept at a constant level. However, the wrapping bag 17 that wraps the part has a maximum length of 850 mm or more, and the part is moved by the carry-in conveyor 20 to the carry-out conveyor 40 in the subsequent area. When an auxiliary suction cup 96 that operates integrally with the movable suction cup 43 is disposed in the area and the movable suction cup 43 lifts and opens the bag mouth of the packaging bag 17 as shown in FIG. 18, the auxiliary suction cup 96 has the same bag bottom. Therefore, the amount of movement of the opposite carry-in conveyor 20 is reduced by the protrusion of the carry-out conveyor 40.

  Note that the wall 97 facing the opening edge of the package 17 loaded in FIG. 17 is provided with a claw 99 for holding the bag mouth that operates with the fluid cylinder 98. In detail, in FIG. 19, this refracted presser claw 99 is rotatably supported by a swing link 101 pivotally supported on a wall 97, and moves between an imaginary line and a solid line by the kinetic power of the fluid cylinder 98. Thus, the movable sucker 43 enters the bag mouth of the open bag 17 and presses the lower side of the bag mouth to secure the opening of the bag 17 by the movable sucker 43. Further, the swinging lever 103 pivotally supported on the lifting material 48 via the pin 102 normally contacts the stopper 104 with its weight and keeps the suction surface of the movable suction cup 43 horizontal, but the lifting material 48 as shown in the figure. The opening edge of the wrapping bag 17 adsorbed on the suction cup 43 is opened by using the movement that the suction cup 43 lifts by receiving the resistance of the loaded wrapping bag 17 by lowering the pressure. The claw 99 enters the bag mouth and presses the bag mouth.

  FIG. 21 shows a configuration in which six bag mounting units 30 are arranged in a plurality of rows corresponding to the case where the number of parts to be sorted increases, and the first motor 121 moves each bag mounting unit 30 to a part. The second motor 122 is configured to move each of the bag loading units 30 in a direction perpendicular to the conveyor line. Further, a means for rotating a large number of bag stacking units 30 along a rotary track and selecting them by transmission record data is also conceivable.

  In FIG. 13, the carrying mechanism 20 that pushes the portion 10 into the wrapping bag 17 has a large thickness at the top and bottom, and it is necessary to prepare a large wrapping bag that is easily caught by the lip of the wrapping bag. The carrying-in mechanism which arrange | positions the scoop-type dish 140 under a conveyor is shown. In such a mechanism, the part 10 is moved onto the dish 140 by the backward movement of the belt conveyor or the forward movement of the flat 140, and the part 10 is wrapped by the protruding movement of the dish 140 and the pushing movement by the plate 145 as shown in FIG. Although it is pushed into the bag 17, in this case as well, based on the size data of the wrapping bag, the protrusion momentum of the dish 140 and the pushing momentum by the plate 145 are controlled, so that the region 10 together with the wrapping bag 17 It is to be transferred to a carry-out conveyor. The push bar 142 disposed in the grooved pattern 141 that supports the dish 140 is operated by a motor 144, and the portion 10 is pushed into the wrapping bag by the plate 145 at the tip. As shown in FIG. 27, the gear 146 rotated by the power of the motor 144 rotates by engaging with the rack teeth formed on the lower surface of the push bar 142 in the groove pattern 141 and moves the plate 145 back and forth. It is.
