Abstract

<P>PROBLEM TO BE SOLVED: To make adjustment for preventing a meat part from being pushed against the bottom of a package by defining a length value (A) of the part by the computation of a controller to prevent twisted packaging of the part by a pressing pressure. <P>SOLUTION: The length value (B) of a provided package 10 is electronically inputted beforehand, thereby being stored in the controller. The package 10 expanded by a beak-shaped hopper is moved (D) from its installed position (C) to an origin point (E) of a temporary sealer 64 based on the recorded signal, and a push-in disk 21 approximately simultaneously pushes the part 40 into the package 10 while tracing. In this case, when the length value of the part is transmitted from the controller, the push-in disk 21 moves from its origin point (F) by a distance corresponding to <G> in response to the transmitted signal and pushes the part into the package. That is, the value of <G> is a computed value wherein the length (B) of the package is added to a distance (H) from the origin point (F) to the origin point (E) of the temporary sealer and the length (A) of the region is subtracted therefrom. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a method and apparatus for bagging large-sized dismantled meat such as beef or pork and supplying it to a vacuum packaging machine.

  For example, pork after dismantling is subjected to bone removal and fat cutting by a large number of workers, and as shown in FIG. 2, five types of parts (hereinafter simply referred to as parts), Kata 01, Catalose 02, Loose 03, Rose 04, and Momo 05. To be filled into a bag and to form a vacuum package, the patent applicant's It can carry out using the apparatus shown by the following patent document 1 by invention.

  That is, the above-mentioned patent document arranges a saddle type hopper on a carry-in track opposite to the rotary vacuum packaging machine, and a pusher that pushes a part into the wrapping bag through the saddle type hopper, When the mouth of the bag is slightly opened to form a gap, the mouth of the bag is expanded by opening the saddle type hopper that enters the gap, while the pusher is used for the saddle type hopper. A configuration is disclosed in which the part is continuously fed into the packaging bag in a balance-type manner, and the part is linearly carried to the vacuum packaging machine integrally with the packaging bag.

  The device has the advantage that the part can be always sent to the fixed position of the vacuum packaging machine because the stroke amount of the pushing board by the fluid cylinder is set constant, but the part that is raw meat is forced by the pushing board. There is a problem that the product value is lowered by being vacuum-packed into a twisted state in the sachet by pushing and subjected to freezing treatment while being twisted, and the original hand clogging work to the sachet is quite mechanized There is a drawback that it is difficult to proceed to. Moreover, each pressure-resistant chamber of, for example, a rotary vacuum packaging machine that wraps this kind of part has the ability to circulate an endless track at intervals of about 2.0 seconds. However, the stroke amount of the push-in type pusher is large, and a lot of time is spent on scraping the opening edge of the wrapping bag in the pressure-resistant chamber. Therefore, one process takes about 7 seconds, and the time interval can correspond to the capacity of the rotary vacuum packaging machine. Therefore, there is a drawback that the package containing the part cannot be supplied.

JP 2004-106937 A JP 2003-252306 A

In the present invention, the portion of the raw meat is reduced in the stroke of the balance-type pusher, the push-in of the pusher into the bag is softened, and the bag is opened at the filling position of the bag. The above-mentioned problem is solved by wrinkling the edges. It conveys the four parts separated in each of the four conveyor lines from 1st to 4th. However, a means for recording the length of each part measured by a measuring instrument arranged in each of these conveyor lines in a controller, and a vertical hopper arranged in each of the four conveyor lines and opened and closed vertically Means for inserting each of the four types of wrapping bags installed in each conveyor line to expand the respective wrapping bags, a pair of bag mouth tension spatulas that enter the wrapping bags integrally with the saddle type hopper, bag Waiting for the timing at which the part reaches the installation position, each part is pushed through the saddle type hopper into the wrapping bag, and then the pusher is moved back to the original position, and the pusher in the pushing direction of the pusher With a pair of upper and lower temporary sealers that move forward and backward along the mutual block motion trajectory,
In each of the four conveyor lines, the individual saddle type hoppers that expand the sachets move each sachet from its installation position (C in FIG. 1) (D amount in the same figure) to The opening edge was sent out to the origin position of the temporary sealer (E in the figure), while the length of each part recorded by the controller (A in the figure) and installed on each of the four conveyor lines Based on the value of the length of each wrapping bag (B in the figure), adding the pusher to the distance H from its origin (F in the figure) to the origin E of the temporary sealer, B, minus, part length A = G, that is, by moving by <(H + B) -A = G>, the gap between the part and the bottom surface of the wrapping bag is adjusted. The opening edge of the wrapping bag is tensed to both sides with a mouth tension spatula, and the wrapping bag is sent to the vacuum packaging machine by performing discontinuous sealing on the opening edge of the wrapping bag with the temporary sealer. As it will be configured.

  While the parts separated into four types are conveyed in the separated state in each of the four conveyor lines from 1 to 4, the lengths of the respective parts are controlled by measuring instruments arranged in the respective conveyor lines. In each of the four conveyor lines, move each sachet together with the individual vertical hoppers that expand the sachet from the installation position (C in FIG. 1) (D amount in the same figure), The opening edge of each wrapping bag is sent to the origin position of the temporary sealer (E in the figure). On the other hand, the length value of each part (A in the figure) recorded by the controller and each of the four conveyors Based on the numerical value of the length of each sachet installed in the line (B in the figure), the distance from the origin (F in the figure) to <the origin F to the origin E of the temporary sealer H + The gap between the part and the bottom surface of the sachet is moved by moving the length of the sachet B-part A = G>. Can be integers, then immediately performs a discontinuous seal the opening edge of the packaging bag at the temporary sealer. In this case, the depth of each of the four types of wrapping bags is recorded by the controller, and the length of the portion is also recorded, so that the tip of the portion can be filled without pressing against the bottom surface of the wrapping bag. Since the discontinuous sealing is performed on the opening edge of the bag with a temporary sealer in advance, the conventional wrinkle removing operation of the bag mouth in the pressure-resistant chamber is eliminated, and the efficiency is improved.

  FIG. 3 is a cross-sectional view of a substantially intermediate portion based on the area limitation of the drawing. The four first to fourth conveyor lines 11, 12, 13, and 14 are originally A series of lowercase letters (a, b, c, d) are connected in series, and each conveyor line is provided with a horizontal row of installation places for wrapping bags 10 of different sizes in the middle part. In addition, as shown in FIG. 4, the said wrapping bag 10 is a tape back | bag formed by affixing many wrapping bags 10 on the armor pile with respect to the two adhesive tapes 15, The said tape 15 is like FIG. Is rolled in the direction of the arrow by the rotation of the roll 16, thereby transferring the wrapping bags 10 one by one.

  As shown in FIG. 7, a part of the side surface of the four conveyor lines in FIG. 3 includes a front conveyor belt 50 and a rear longitudinal belt 17. It is conveyed to the moving belt 17. The longitudinally moving belt 17 includes a saddle type hopper 20 and a pushing board 21. The details of the saddle type hopper 20 are as shown in FIG. 19 and a pair of bag mouth tension spatulas 31 are provided on the lower surface of the hopper.

  More specifically, as shown in the plan view of FIG. 8, the longitudinally moving belt 17 and the saddle type hopper 20 supported by a pair of rod-shaped guides 23 on both sides via a slider 22 are provided along the guide 23. It can be displaced integrally. On the other hand, the pushing platen 21 supported by a separate guide 25 via the arm 24 is independently moved back and forth by the power of the linear motion motor 26 formed of a fluid cylinder.

  The above-described saddle type hopper 20 specifically shown in FIG. 9 is supported by the above-described guide through the bracket 33 and the shaft rod 29, but the lower groove member 19 has many free-rotating members. The bar roller 27 is provided for the purpose of avoiding friction with the moving part. The operation lever 28 on one side opens the tip of the lower member 19 up and down with the shaft rod 29 as a fulcrum, and the operation lever on the other side. Reference numeral 30 denotes a structure in which the tips of the upper and lower groove members 18 and 19 are moved up and down together.

  The saddle type hopper 20 in FIG. 5 is normally in a state in which the bag is closed as indicated by a virtual line 20a, advances in that state, and then enters the state-of-the-art packaging bag 10 of the tape back. By opening, the state-of-the-art packaging bag 10 is peeled off from the adhesive tape 15 and opened. As a result, the system for pushing the portion 40 waiting on the back-and-forth moving belt 17 into the wrapping bag 10 by the pushing board 21 is completed.

  Although it has been explained that the tip of the bag mouth tension spatula 31 located on the lower side of the saddle type hopper 20 in FIG. 5 has already moved up and down substantially in the same body as the lower groove mold member 19, FIG. The mechanism for opening and closing the spatula 31 on both sides and swinging up and down is shown. That is, by operating the protruding member 34 up and down, the tip of the bag mouth tension spatula 31 is displaced up and down via the cylindrical shaft 33 around the shaft 32. The elasticity of the two coil springs 35 on both sides is biased so as to reduce the distance between the tips of the spatula 31 via a pair of panels 36, and the elasticity of the panel 36 is resisted against the elasticity of these coil springs 35. By increasing the distance between the pair of pins 37 protruding downward, the relative distance between the bag mouth tension spatula 31 is increased. In this case, when the blocking resistance of the opening edge of the wrapping bag 10 is applied to the spatula 31, the elasticity of the separate coil spring 38 buffers it.

  Depending on the meat dismantling factory, if there is a place where the part is shipped in 4 divisions without separating the Kata 01 and the Catalose 02 in FIG. 2, the Kata 01 and the Catalose 02 are separated and the part is divided into 5 parts. In this case, first, a case where a part is processed in four parts will be described. That is, the carry-in conveyor 41 in FIG. 3 conveys each part 40 in a column, but an image sensor 42 connected to the controller 44 exists in the passage area of the part 40.

  As shown in FIG. 11, the image sensor 42 measures the thickness from the cross section of each passing part 40 with infrared rays 43 emitted from a large number of lamps arranged on the side surface and the top surface, The parts are classified into A and B in FIG. 12, and the sorted electronic information is recorded in the controller 44. And the length of the same part is measured from the passage time of the same part 40, and the part is divided into two parts A1, A2 and B1, B2 on the basis of the length, and finally divided into four parts to control this classification signal information. Record in instrument 44. In order to reliably separate the four types of parts, a non-measurement area 200 of about 2.0 cm is set at the boundary, and the height or length of the part corresponding to this non-measurement area is A1, Allocation between A2, B1 and B2 alternately to prevent measurement confusion.

  In this way, the separation mechanism 45 arranged following the carry-in conveyor 41 of FIG. 3 has four conveyor lines 11 to 14 as indicated by arrows based on the recording signal 46 from the controller 44. Move to 4 minutes. As for the sorting mechanism 45, a guide slider is provided for each of a large number of bar members installed in parallel between the endless chains on both sides, and each endless chain is rotated and the slider is displaced along the bar. It is most efficient and desirable to set the direction of part separation.

  As a result, the portion 40 transferred to the transport conveyor 50 (any of the four parallelly arranged) in FIG. 7 is further transported and transported to the position of the stop sensor 52 in the longitudinal conveyor 17. In this case, the pushing board 21 becomes an obstacle to the transfer of the portion 40, but as shown in FIG. 13, the slide is displaced along the guide 23 by being pulled by the movement of the magnetic piston 55 in the cylinder constituting the linear motor 25. Since the cylinder 57 provided in the block 56 connects the arm 24 of the pusher plate 21 to the piston rod 58, the movement of the pusher plate 21 moved up by the piston rod 58 eliminates the hindrance to the progress of the portion 40. Then, from the state shown in FIG. 5, the pushing board 21 pushes the portion 40 into the bag 10 through the saddle type hopper 20, and in parallel with this pushing movement, the saddle type hopper 20 and the bag mouth tension as shown in FIG. The spatula 31 is advanced to carry the wrapping bag 10 and the part 40 onto the sword conveyor 60.

  Referring to the plan view shown in FIG. 1, the supply movement of the part 40 will be described. The distance (H) from the origin position (F) of the pushing board 21 to the origin position (E) of the temporary sealer 64 is unchanged, The length numerical value (B) of the placed bag 10 is electronically input in advance and stored in the controller. Therefore, based on the recording signal in the controller, the packaging bag 10 expanded by the saddle type hopper is moved (D) from the installation position (C) to the origin position (E) of the temporary sealer 64, and the pushing board 21 is moved almost simultaneously. 40 is pushed into the package 10 in a tracking state. In this case, there is some error in the length of the portion 40 to be carried one after another, and when the numerical value of the length of the portion is transmitted from the controller, the pushing board 21 receives the transmission signal and the origin (F) Move the distance corresponding to <G> and push the part into the sachet. That is, the value of <G> is obtained by adding the length (B) of the wrapping bag to the distance (H) from the origin (F) to the origin (E) of the temporary sealer, and from the value, This is a calculated value obtained by subtracting the length (A). In this calculation, if the length value (A) of the part is set slightly larger, the same part can be adjusted so as not to be pressed against the bottom of the wrapping bag. When the pressing occurs, the twisted packaging of the part can be prevented.

  FIG. 14 is a perspective view of a mechanism for making the block motion of the upper and lower temporary sealers 64, 65. The gate-shaped frame 68 slidably supported by a pair of horizontal guide rails 67 on both sides has a pair of sleeves on the inside thereof. The upper temporary sealer 64 is supported on the upper end of the slide bar 70 supported by 69, and the lower temporary sealer 65 is slidably supported on both slide bars 70 at both ends. Therefore, by operating the lever 72 with the first rod 71 and rotating the first shaft 73 forward and backward, the link 74 moves the second rod 75 up and down, resulting in forward and reverse rotation of the bell crank 76 via the slide bar 70. The upper temporary sealer 64 is lowered while the bell crank 76 raises the lower temporary sealer 65 along the slide bar 70. In short, the pair of upper and lower temporary sealers relatively approach and separate. Further, the second shaft 77 is rotated forward and backward by another lever, the swinging motion of the lever 78 is transmitted to the portal frame 68, and the frame is reciprocated along the guide rail 67, whereby the upper and lower temporary sealers 64 are moved. , 65 perform relative proc motion motion.

  Returning to the state explanation, when the opening edge of the wrapping bag reaches the position along the temporary sealer 64, the saddle type hopper 20 and the pushing board 21 are retracted from FIG. While the ten mouths are tensioned on both sides, the bag mouth is pinched with the upper and lower temporary sealers 63 and 64 to perform spot sealing. In short, the sawtooth conveyor 60 is formed by laying a large number of parallel bars 62 between a pair of chains 61 on both sides, and a pair of upper and lower sides of a specific gap 59 in which the interval between the parallel bars 62 is partially expanded. When the chain 60 is rotated clockwise by the power of the motor 65, the temporary sealers 63 and 64 also perform block motion motion along the arrow tracks 66 and 67, respectively. While carrying the part, the spot seal 80 is applied to the bag mouth that is tensioned with the spatula 31 as shown in FIG.

  Each sachet that has been spot-sealed and wrinkled at the bag mouth as described above reaches the four standby conveyors 81 at the end of the four conveyor lines in FIG. Thus, each of the wrapped bags is temporarily stopped on each of the standby conveyors 81, and thereafter, each of the wrapped bags is sequentially arranged at a constant time interval, in a single row state by the collective transport mechanism 83, and passed through the carry-out conveyor 84. It is fed into each pressure-resistant chamber 86 of the rotary vacuum packaging machine 85.

  FIG. 16 shows the pressure-resistant chamber 86, which is composed of a flat surface plate 87 and a cover material 88 covering the flat surface plate 87. The surface plate includes a seal base 89, and the cover material includes a seal bar 90. After the air in the pressure-resistant chamber 86 is removed, the seal bar 90 is lowered on the seal base 89 and the wrapping bag 40 is welded at the site 10. In this case, the seal base and the seal bar are equipped with 2 The next wrinkle removal mechanism stretches the wrapping bag on both sides at the site 10.

  That is, as shown in FIG. 17, a pair of left and right slide bases 92 attracted by a coil spring 91 are supported by the pins 93 on the front surface of the seal base 87, while a swing link 94 is interposed on the front surface of the seal bar 90. A pair of left and right swing bars 95 are installed, and a separate coil spring 96 is installed between the swing bars 95. Thus, in the process in which the upper and lower bars 87 and 90 are relatively close to each other, the pair of swing bars 95 receives the collision resistance of the slide base 92, so that the pair of swing bars 95 links against the attractive force of the coil spring 96. 94, but the friction between the slide base 92 and the swing bar 95 is increased by the attractive force of the coil springs 91, 96. And stretched on both sides. That is, as shown in FIG. 15, the bag 40 is preliminarily wrinkled on the edge of the bag by a spot seal 80 in advance and the large wrinkles at the site 10 are removed. It is possible to remove the wrinkle of the part as shown by the virtual line 97 by simply opening it.

  In some meat dismantling factories, the separation worker does not install the carry-in conveyor 41 and the separation mechanism 45 in FIG. 3, and the separation worker sorts and transfers the parts directly to the four conveyor lines 11 to 14 with the sense of the worker. Since there is a place to process, in such a case, the photoelectric measuring instrument 51 is installed so as to straddle the four conveyor belts 50, and the length of each part measured by the photoelectric measuring instrument 51 is used instead of the image sensor 42. Can be recorded by the controller 44, and the above-described control can be performed based on the recorded information.

  In the above description, the cata 01 and the catalose 02 in FIG. 2 are integrally transported without being separated. However, depending on the dismantling factory, there are places where these are separated into five parts. In this case, since there is not much difference in size between Kata 01 and Catalose 02, as shown in FIG. 19, these two parts are transported together with the fourth conveyor line, and the other three separation parts are Other means for transporting and packaging by the first to third conveyor lines will be described.

  The speed of the conveyor belt 41 in FIG. 18 is the fastest, being 1 m per second, and there is a problem that the inertia of the part works greatly at a speed higher than that. The five types of pork have a length of about 70 cm in the longest loin 03. In order to sequentially mount the parts on the conveyor belt 41 rotating under the above conditions, 1.5 parts between the parts is required. An interval of at least 2 seconds is necessary, and these five types of parts are fed together with Kata 01 and Catalose 02 to the fourth conveyor line 11, and the other three kinds of parts are sent to the first to third conveyor lines. Thus, the respective parts sequentially reach the first standby line in FIG. 19 at intervals of about 1.5 seconds. However, it takes two times the arrival time of the other three parts to reach the first standby line in the fourth conveyor line 11 together, Compared to the other three types of parts, the time interval of supply to the vacuum packaging machine must be increased accordingly. Moreover, as shown in FIG. 18, it is a condition that each part is transported in order according to the type, and it is natural that the transportation order of each part in the dismantling factory is mixed, and the arrival interval of each part is Since there is a possibility of narrowing and spreading, supply means for improving this point will be described below.

  The high-speed transport addition means 100 shown in FIG. 20 arranges a bypass conveyor that rotates at high speed in the upper region of the fourth conveyor line 14. In this bypass conveyor, the front belt 47, which is normally in a horizontal state like an imaginary line, descends like a solid line with a separation signal from a controller that monitors the distance between the cata and catalose and picked up from the conveyor line 14 Site 02 is bypassed to the upper section. On the other hand, the rear belt 48 descends like an imaginary line in accordance with the interval of the parts recorded by the controller, and guides the already picked up part to the conveyor line 14 again. In this case, with a speed difference between the lower conveyor line 14 and the upper bypass conveyor, the part 01 passing through the lower conveyor line 14 is tracked by the subsequent part 02 by the upper bypass conveyor. It narrows the distance between the two parts.

  On the other hand, the high-speed carrying addition means 100 shown in FIG. 21 is provided with a separate strap belt 49 that is driven at high speed by the motor 53 in each gap of the conveyor line 14 formed by a plurality of strap belts. When the delay interval of the rear part 02 with respect to the part 01 is detected, the pusher 97 accelerates the part 02 by pushing up the cord belt 49 that is driven at high speed by the rotation of the lever 99 about the pin 98, The distance between the two parts is narrowed by tracking the subsequent part 02 with respect to the front part 01. Each of the above high-speed transport addition means 100 is not limited to the means dedicated to the fourth conveyor line 14, but is disposed on each of the other first to third conveyor lines, and means for correcting the front-rear part interval. can do.

  The retracting mechanisms 110 are arranged on the four conveyor lines 11 to 14 in FIG. 3 so that the distance between the parts does not become extremely large. As shown in FIG. 22, the plane of the mechanism forms a lift conveyor by supporting a conveyor body 114 formed by supporting a number of rollers 112 inside a rectangular frame frame 111 and supporting a pair of endless chains 113. As described above, the chain 113 supports a large number of the conveyor bodies 114 at regular intervals.

  By transmitting the power of the motor 116 to the chain 113 via the pulley 117, the frame 111 moves upward or downward. 5 to 6 takes about 3 to 4 seconds for the part bagging process, whereas the part arrival interval in FIG. 19 is less than 2 seconds. Depending on the line, an excessive phenomenon of the part may occur. 24, the distance between the front and rear portions 40 conveyed by the conveyor belt 50 in FIG. 24 is captured by the sensor 115, and when the distance is closer than necessary, the second motor 118 is interlocked via the timing belt 119. When each roller 112 connected to the state is rotated to draw in a part (virtual line), the part is retracted to the upper area as indicated by a virtual line 120 in FIG. It is possible to feed the parts that have been retracted by lowering 111 between the parts with a wide interval. Of the 1 pork, in particular, Kata 01 and Catalose 02 have a condition that they are packaged as a set, and the interval is wider than other parts, but twice as much as other parts. Since the quantity is large and may be excessive, the evacuation mechanism is expected to be effective at least in the fourth conveyor line.

FIG. 25 shows a vacuum packaging machine having an efficiency substantially equal to that of the rotary vacuum packaging machine. As already described, the carry-out conveyor 84 of the packaging bag 10 containing the part 10 and having the spot seal 80 applied to the bag mouth is shown. The belt conveyor 130 is arranged at the end of the belt so as to intersect the carrying-out direction of the carry-out conveyor, and a pair of pressure-resistant chambers 131 and 132 are installed on both the carry-out side of the belt conveyor. The conveyance means 133 is installed inside. The belt conveyor 130 rotates in both lateral directions as indicated by arrows 135 and 136, and the wrapping bags 40 transferred from the carry-out conveyor are arranged in parallel. Packaging. Each of these pressure-resistant chambers has a capacity for accommodating four or more wrapping bags, and can utilize the two pressure-resistant chambers alternately to demonstrate the ability not inferior to the rotary type, and the sealing mechanism described in FIG. Equip.
