Description

Technical Field

[0001] This invention belongs to the field of packaging equipment technology, and more specifically, relates to a five-pack sealing and cutting machine for goods. Background Technology

[0002] Snacks like potato chips and cookies are usually packaged in plastic bags, often connected in bundles for easy bulk sales.

[0003] Patent 201911031182.8 discloses a packaging machine for single-bag combination packaging. The packaging machine includes a feeding conveying mechanism, a dual-servo feeding mechanism, a bag-supporting feeding mechanism, a bag-forming mechanism, a side-sealing mechanism, and a horizontal sealing mechanism. The feeding conveying mechanism can transport single bags to the dual-servo feeding mechanism. The dual-servo feeding mechanism arranges multiple single bags into a row and pushes them into the bag-supporting feeding mechanism. The bag-supporting feeding mechanism gathers the multiple single bags arranged in a row together and then pushes them into the already formed packaging bag in the bag-forming mechanism.

[0004] The above packaging machine is designed for single-packaged goods. The single-packaged goods can be arranged and pushed into the packaging bag. However, multi-packaged goods cannot be simply arranged. They need to be folded into a suitable position to reduce the space occupied before being arranged and pushed into the packaging bag.

[0005] Therefore, existing packaging machines cannot package and seal multi-packed goods, and lack a structure that can fold multi-packed goods. Summary of the Invention

[0006] The main objective of this invention is to provide a five-pack product sealing and cutting machine, which can fold and adjust the posture of five-pack products to facilitate pushing them into packaging bags.

[0007] According to a first aspect of the present invention, a five-pack product sealing and cutting machine is provided, comprising a feeding unit, a folding unit, a flipping unit, an arranging unit, a bag-making unit, and a sealing unit. The feeding unit conveys the five-pack products in a horizontal position to the folding unit. The folding unit folds the five-pack products and conveys the folded five-pack products to the flipping unit. The flipping unit flips the folded five-pack products into a flat position and conveys them to the arranging unit. The arranging unit arranges multiple flat-positioned five-pack products into a row and conveys them to a packaging bag produced by the bag-making unit. The sealing unit seals the packaging bag.

[0008] In the above-mentioned five-pack sealing and cutting machine, the folding unit includes two side plates arranged at intervals. The two side plates are connected by rollers. There are two rollers arranged at intervals in the horizontal direction. A conveyor belt group is driven connected to the two rollers. There are two conveyor belt groups arranged at intervals in the axial direction of the rollers. A positioning plate is provided above the conveyor belt group. A channel is formed between the two side plates. The channel is connected to the feeding unit.

[0009] The feeding unit transports the five-pack of goods onto the conveyor belt assembly and positions the center package of the five-pack of goods on the positioning plate.

[0010] A first folding push rod assembly and a second folding push rod assembly are provided between the two conveyor belt groups. There are two first folding push rod assemblies located on both sides of the positioning plate, and there are two second folding push rod assemblies located on both sides of the positioning plate. The first folding push rod assembly is located on the side of the second folding push rod assembly away from the positioning plate. The first folding push rod assembly pushes the edge package of the five-pack goods to rotate upward along the direction close to the positioning plate, and the second folding push rod assembly pushes the package of the five-pack goods adjacent to the edge package to rotate upward along the direction close to the positioning plate.

[0011] One of the side plates has a first opening, and the other side plate has a second opening. Both the first opening and the second opening correspond to the positioning plate. A first cylinder is provided on the side of the first opening away from the positioning plate. A push plate is provided at the output end of the first cylinder. The first cylinder can drive the push plate to push the folded five-pack of goods on the positioning plate out of the second opening and transport it to the flipping unit.

[0012] In the aforementioned five-pack sealing and cutting machine, a pressing module is provided between the first folding push rod assembly and the second folding push rod assembly. The pressing module includes a second cylinder and a mounting base disposed at the output end of the second cylinder. A third cylinder is provided on the mounting base. The extension and retraction direction of the third cylinder is parallel to the axial direction of the roller. The piston rod of the third cylinder can reach above the conveyor belt assembly. The third cylinder drives the mounting base to rise and fall, so that the piston rod of the third cylinder presses the edge of the five-pack of goods and the connection between the package and the adjacent package.

[0013] In the aforementioned five-pack product sealing and cutting machine, two limiting rods are provided above the conveyor belt assembly. The two limiting rods are arranged at intervals along the moving direction of the five-pack products and are symmetrically arranged about the positioning plate. The two limiting rods are raised and lowered under the drive of the fourth cylinder, and the folded five-pack products can be stuck between the two limiting rods.

[0014] In the above-mentioned five-pack product sealing and cutting machine, a first pressure plate is provided above the positioning plate. The first pressure plate is raised and lowered under the drive of the fifth cylinder. The bottom contour of the first pressure plate is adapted to the top contour of the folded five-pack product. After the first pressure plate is lowered, the first pressure plate, the positioning plate and the limiting rod cooperate to maintain the posture of the folded five-pack product.

[0015] In the above-mentioned five-pack product sealing and cutting machine, the flipping unit includes a receiving module, a pressing module and a pushing module. The pressing module includes a sixth cylinder and a second pressure plate disposed at the output end of the sixth cylinder. The sixth cylinder drives the second pressure plate to rise and fall.

[0016] The receiving module includes a slide and a seventh cylinder that drives the slide to slide along the moving direction of the push plate. The slide is located on the side of the second opening away from the positioning plate. The slide is provided with a rotating shaft, the axis of which is parallel to the extension direction of the channel. The rotating shaft rotates under the drive of a first driving member. A receiving frame is fixed on the rotating shaft, and a receiving plate is fixed on the slide. The receiving frame is used to load the folded five-pack of goods. The rotating shaft drives the receiving frame to rotate so that the folded five-pack of goods flips downward and backward by 90 degrees. The flipped five-pack of goods will be located above the receiving plate. The slide slides back and forth so that the receiving frame receives the five-pack of goods from the second opening or places the flipped five-pack of goods under the second pressure plate. The action of the second pressure plate can push the flipped five-pack of goods onto the receiving plate.

[0017] The pushing module includes an eighth cylinder and a pusher block disposed at the output end of the eighth cylinder. The extension and retraction direction of the eighth cylinder is parallel to the axial direction of the rotating shaft. Driven by the eighth cylinder, the pusher block can push the five-pack of goods on the receiving plate to the arranging unit.

[0018] In the above-mentioned five-pack product sealing and cutting machine, one end of the receiving plate is fixedly connected to the slide in the sliding direction of the slide, and the other end of the receiving plate is provided with a retaining edge, which cooperates with the slide to prevent the five-pack products on the receiving plate from spreading out.

[0019] In the above-mentioned five-pack sealing and cutting machine, the arrangement unit includes a buffer plate, and the receiving plate can be docked with the buffer plate;

[0020] The buffer plate is provided with an arranging plate, the extension direction of which is parallel to the axis of the rotating shaft. The arranging plate can move along the sliding direction of the slide under the drive of the second driving member. The pusher pushes the five-pack of goods on the receiving plate onto the buffer plate, and the arranging plate pushes the five-pack of goods arranged on the buffer plate into the packaging bag.

[0021] The aforementioned five-pack sealing and cutting machine also includes a baffle plate, which is raised and lowered under the drive of the ninth cylinder.

[0022] When the blocking plate rises, it is located on the side of the receiving plate close to the buffer plate, and it is opposite to the push block; when the blocking plate falls, it is lower than the upper surface of the buffer plate.

[0023] In the above-mentioned five-pack sealing and cutting machine, the buffer plate is provided with an arc-shaped piece, the arc-shaped piece is opposite to the push block, and the push block can move along the axial direction of the rotating shaft;

[0024] There is a gap between the arrangement plate and the buffer plate, and the arc-shaped piece is located in the gap. The blocking plate, the arrangement plate and the arc-shaped piece cooperate to restrict the five-pack of goods on the buffer plate to prevent them from falling apart.

[0025] One of the above-described technical solutions of the present invention has at least one of the following advantages or beneficial effects:

[0026] In this invention, a five-pack of goods can be folded from a horizontal position into a U-shaped position, then flipped flat, arranged, pushed into a packaging bag, and then sealed. Because it is folded into a U-shaped position, the space occupied by the five-pack of goods can be reduced, and the packaging of the five-pack of goods can be more automated.

[0045] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0046] The following disclosure provides many different implementations or examples for different ways of implementing the present invention.

[0047] Reference Figures 1 to 10 As shown, a five-pack product sealing and cutting machine includes a feeding unit 1, a folding unit 2, a flipping unit 3, an arranging unit 4, a bag making unit 5, and a sealing unit 6. The feeding unit 1 conveys the five-pack products in a horizontal position to the folding unit 2. The folding unit 2 folds the five-pack products and conveys the folded five-pack products to the flipping unit 3. The flipping unit 3 flips the folded five-pack products into a flat position and conveys them to the arranging unit 4. The arranging unit 4 arranges multiple flat five-pack products into a row and then conveys them to the packaging bag made by the bag making unit 5. The sealing unit 6 seals the packaging bag.

[0048] The structure of the feeding unit 1 can refer to the feeding conveying mechanism in patent 201911031182.8. Of course, the feeding unit 1 can also be a conveyor belt device or a chain conveyor device, which is responsible for conveying the original horizontally placed five-pack goods to the folding unit 2.

[0049] Reference Figures 2 to 6 The folding unit 2 includes two side plates 21 arranged at intervals. The two side plates 21 are connected by rollers 22. There are two rollers 22 arranged at intervals in the horizontal direction. The two rollers 22 are connected to a conveyor belt group 23. There are two conveyor belt groups 23 arranged at intervals in the axial direction of the rollers 22. A positioning plate 24 is provided above the conveyor belt group 23. A channel is formed between the two side plates 21. The channel is connected to the feeding unit 1.

[0050] The feeding unit 1 transports the five-pack of goods to the conveyor belt group 23 and positions the center package of the five-pack of goods on the positioning plate 24.

[0051] A first folding push rod assembly 25 and a second folding push rod assembly 26 are provided between the two conveyor belt groups 23. There are two first folding push rod assemblies 25 located on both sides of the positioning plate 24, and there are two second folding push rod assemblies 26 located on both sides of the positioning plate 24. The first folding push rod assembly 25 is located on the side of the second folding push rod assembly 26 away from the positioning plate 24. The first folding push rod assembly 25 pushes the edge package of the five-pack goods to rotate upward along the direction close to the positioning plate 24, and the second folding push rod assembly 26 pushes the package of the five-pack goods adjacent to the edge package to rotate upward along the direction close to the positioning plate 24.

[0052] Two limiting rods 27 are provided above the conveyor belt assembly 23. The two limiting rods 27 are arranged at intervals along the movement direction of the five-pack of goods. The two limiting rods 27 are symmetrically arranged about the positioning plate 24. The two limiting rods 27 are raised and lowered under the drive of the fourth cylinder 271. A first pressure plate 28 is provided above the positioning plate 24. The first pressure plate 28 is raised and lowered under the drive of the fifth cylinder 281. When the first pressure plate 28 is lowered, the first pressure plate 28, the positioning plate 24 and the limiting rods 27 cooperate to maintain the posture of the folded five-pack of goods.

[0053] One side plate 21 is provided with a first opening 211, and the other side plate 21 is provided with a second opening 212. The first opening 211 and the second opening 212 are both corresponding to the positioning plate 24. A first cylinder 213 is provided on the side of the first opening 211 away from the positioning plate 24, and a push plate 214 is provided at the output end of the first cylinder 213.

[0054] The two side plates 21 form a channel. When the five-pack of goods is conveyed onto the conveyor belt assembly 23, the channel can restrict the position of the five-pack of goods, preventing them from moving around. Since the conveyor belt assemblies 23 are spaced apart, there is a gap between the two conveyor belt assemblies 23 to facilitate the operation of the first folding push rod assembly 25 and the second folding push rod assembly 26. The central package of the five-pack of goods is located on the positioning plate 24, so the central package of the five-pack of goods does not need to be folded. When the central package of the five-pack of goods reaches the positioning plate 24, the first folding push rod assembly... First, component 25 activates, pushing the edge packages of the five-pack upwards along the direction close to the positioning plate 24. This is the first fold, folding the two edge packages of the five-pack upwards. Next, the second folding pusher assembly 26 activates, pushing the package adjacent to the edge packages of the five-pack upwards along the direction close to the positioning plate 24. This is the second fold, resulting in a U-shaped five-pack after folding, reducing the space occupied by the folded package. (Refer to...) Figure 2 This illustrates the contrast between the original and folded appearance of the five-pack of goods.

[0055] Before folding, the first pressure plate 28 will descend. The bottom contour of the first pressure plate 28 facilitates the shaping of the five-pack of goods during folding. The limiting rod 27 is initially in a low position, and the five-pack of goods will be above the limiting rod 27. When the second folding push rod assembly 26 completes the pushing action, the limiting rod 27 will rise, so that the folded five-pack of goods is stuck between the two limiting rods 27. The first pressure plate 28, the positioning plate 24 and the limiting rod 27 work together to maintain the posture of the folded five-pack of goods and prevent the five-pack of goods from falling apart.

[0056] When the first pressure plate 28, the limiting rod 27 and the positioning plate 24 hold the five-pack of goods, the first cylinder 213 will be activated. The first cylinder 213 can drive the push plate 214 to push the five-pack of goods held in the posture out of the second opening 212, so that the folded five-pack of goods can enter the flipping unit 3.

[0057] The push plate 214 can be provided with corresponding notches to avoid the limit rod 27 and the first pressure plate 28.

[0058] In practice, there is also an external frame, the side plate 21 can be fixed on the frame, and the positioning plate 24 is fixed on the side plate 21.

[0059] In this embodiment, the conveyor belt assembly 23 includes two rubber rings, which can increase the support points to ensure that the five-pack of goods will not fall off. One of the rollers 22 rotates under the drive of the motor. When the five-pack of goods is conveyed in, the roller 22 is also rotating to assist the movement of the five-pack of goods and prevent the five-pack of goods from getting stuck on the conveyor belt assembly 23.

[0060] Furthermore, the length of the channel formed by the two side plates 21 is adapted to the length of the five-pack of goods. The feeding unit 1 is connected to one end of the channel, and a corresponding sensor can be set at the end of the channel away from the feeding unit 1. After the product is detected, it can be determined that the five-pack of goods has completely entered the channel, and the feeding unit 1 stops conveying. At this time, the center of the five-pack of goods will be on the positioning plate 24.

[0061] In this embodiment, a pressing module 29 is provided between the first folding push rod assembly 25 and the second folding push rod assembly 26. The pressing module 29 includes a second cylinder 291 and a mounting base 292 disposed at the output end of the second cylinder 291. A third cylinder 293 is disposed on the mounting base 292. The extension and retraction direction of the third cylinder 293 is parallel to the axial direction of the roller 22. The piston rod of the third cylinder 293 can reach above the conveyor belt assembly 23. The third cylinder 293 drives the mounting base 292 to rise and fall.

[0062] Before the first folding push rod assembly 25 is activated, the mounting base 292 is in a high position. The third cylinder 293 is activated first, allowing its piston rod to pass through the side plate 21 and reach above the connection between the edge package and the adjacent package of the five-pack. Then, the second cylinder 291 is activated, causing the mounting base 292 to descend, thereby allowing the piston rod of the third cylinder 293 to press the connection between the edge package and the adjacent package of the five-pack. After that, the first folding push rod assembly 25 is activated again to ensure that the adjacent packages do not move when the edge package of the five-pack is pushed, thus ensuring the folding effect. After that, the second cylinder 291 and the third cylinder 293 are reset, and the second folding push rod assembly 26 is activated again.

[0063] In this embodiment, both the first folding push rod assembly 25 and the second folding push rod assembly 26 are composed of a cylinder and a pad. The pad is located at the output end of the cylinder. The cylinder drives the pad to move, thereby pushing the five-pack of goods to rotate.

[0064] Reference Figures 7 to 8 The flipping unit 3 includes a receiving module 31, a pressing module 32 and a pushing module 33. The pressing module 32 includes a sixth cylinder 321 and a second pressure plate 322 disposed at the output end of the sixth cylinder 321. The sixth cylinder 321 drives the second pressure plate 322 to rise and fall.

[0065] The receiving module 31 includes a slide 311 and a seventh cylinder 312 that drives the slide 311 to slide along the moving direction of the push plate 214. The slide 311 is located on the side of the second opening 212 away from the positioning plate 24. A rotating shaft 313 is provided on the slide 311. The axis of the rotating shaft 313 is parallel to the extension direction of the channel. The rotating shaft 313 rotates under the drive of the first driving member 314. A receiving frame 315 is fixed on the rotating shaft 313. A receiving plate 316 is fixed on the slide 311. The receiving frame 315 is used to load the folded five-pack of goods. The slide 311 slides back and forth to allow the receiving frame 315 to receive the five-pack of goods from the second opening 212 or to allow the folded five-pack of goods to be located under the second pressure plate 322.

[0066] The feeding module 33 includes an eighth cylinder 331 and a pusher block 332 disposed at the output end of the eighth cylinder 331. The extension and retraction direction of the eighth cylinder 331 is parallel to the axial direction of the rotating shaft 313.

[0067] With the movement of the slide block 311, the receiving frame 315 is positioned close to the second opening 212. The second opening 212 transports the folded five-pack of goods into the receiving frame. Then, the pivot 313 drives the receiving frame 315 to rotate downwards and backwards by 90 degrees, so that the five-pack of goods becomes flat and reaches above the receiving plate 316. At the same time, the slide block 311 also moves away from the second opening 212, so that the rotated five-pack of goods is located below the second pressure plate 322. Then, the second pressure plate 322 moves to push the five-pack of goods in the receiving frame 315 onto the receiving plate 316. At this time, the five-pack of goods is placed on the receiving plate 316 in a flat position and is not easy to fall apart. Then, the pusher block 332 moves again to push the five-pack of goods on the receiving plate 316 to the arrangement unit 4.

[0068] In this embodiment, the receiving frame 315 includes a rectangular frame. The cavity constructed by the rectangular frame can accommodate and restrict the folded five-pack of goods, preventing the folded five-pack of goods from spreading out. One of the open ends of the cavity is provided with a limiting plate, which is fixed to the rectangular frame. When the receiving frame 315 receives the product from the second opening 212, the limiting plate is located on the side of the rectangular frame away from the second opening 212, thereby preventing the folded five-pack of goods from leaving the cavity. When the receiving frame 315 is rotated 90 degrees downwards, the limiting plate will be located on the side of the rectangular frame away from the receiving plate 316, and the limiting plate will not completely block the open end of the cavity, allowing the second pressure plate 322 to enter the cavity normally.

[0069] In this embodiment, one end of the receiving plate 316 is fixedly connected to the slide 311 in the sliding direction of the slide 311, and the other end of the receiving plate 316 is provided with a retaining edge 317. The retaining edge 317 cooperates with the slide 311 to prevent the five-pack of goods on the receiving plate 316 from falling apart.

[0070] In this embodiment, the first driving component 314 is an electric motor.

[0071] Reference Figures 9 to 10 The arrangement unit 4 includes a buffer plate 41, and the receiving plate 316 can be connected to the buffer plate 41.

[0072] The buffer plate 41 is provided with an arranging plate 42. The extension direction of the arranging plate 42 is parallel to the axis of the rotating shaft 313. The arranging plate 42 can move along the sliding direction of the slide block 311 under the drive of the second driving member 43. The push block 332 pushes the five-pack of goods on the receiving plate 316 onto the buffer plate 41, and the arranging plate 42 pushes the five-pack of goods arranged on the buffer plate 41 into the packaging bag.

[0073] It also includes a baffle plate 44, which is raised and lowered by the ninth cylinder 45;

[0074] When the baffle plate 44 rises, it is located on the side of the receiving plate 316 near the buffer plate 41, and the baffle plate 44 is opposite to the push block 332; when the baffle plate 44 falls, it is lower than the upper surface of the buffer plate 41.

[0075] The buffer plate 41 is provided with an arc-shaped piece 46, which is opposite to the push block 332. The push block 332 can move along the axial direction of the rotating shaft 313.

[0076] There is a gap between the arrangement plate 42 and the buffer plate 41, and the arc-shaped piece 46 is located in the gap. The blocking plate 44, the arrangement plate 42 and the arc-shaped piece 46 cooperate to restrict the five-pack of goods on the buffer plate 41 to prevent them from falling apart.

[0077] During the arrangement, the curved plate 46 is positioned close to the receiving plate 316, and the blocking plate 44 is initially in a lowered position. Then, the pusher block 332 pushes the five-pack of goods onto the buffer plate 41, causing the blocking plate 44 to rise. The blocking plate 44, the arranging plate 42, and the curved plate 46 work together to restrict the five-pack of goods on the buffer plate 41 to prevent them from scattering. Since the curved plate 46 is movable, after the blocking plate 44 descends again, the pusher block 332 can continue to push the five-pack of goods onto the buffer plate 41. The five-pack of goods will push the curved plate 46 to move until a row of five-pack of goods is arranged on the buffer plate 41. Then, the arranging plate 42 moves to push the row of five-pack of goods into the packaging bag. Alternatively, the row of five-pack of goods can be pushed to the next station on the buffer plate 41 first, and then pushed into the packaging bag all at once after arranging more rows.

[0078] In this embodiment, the packaging bag is located at the end of the buffer plate 41 away from the folding unit 2. The five-pack of goods is folded into a U-shape. Therefore, when the arranging plate 42 pushes the five-pack of goods to move, it will contact the side of the five-pack of goods with the concave part. In this way, the arranging plate 42 will not cause the five-pack of goods to fall apart when it is pushed. This is also why the flipping unit 3 flips the five-pack of goods in a specific direction.

[0079] In this embodiment, guide plates 47 can be fixed on the buffer plate 41. There are two guide plates 47, and the arranged five-pack of goods can be located between the guide plates 47. When the arrangement plate 42 pushes the five-pack of goods to move, the guide plates 47 can restrict the five-pack of goods so that they will not scatter after leaving the blocking plate 44 and the arc-shaped piece 46.

[0080] In this embodiment, a guide rail 411 is provided on the buffer plate 41. The extension direction of the guide rail 411 is parallel to the axial direction of the rotating shaft 313. A slider 412 is provided on the guide rail 411. An arc-shaped piece 46 is disposed on the slider 412 so that the arc-shaped piece 46 can move. A pulley 413 is provided at one end of the guide rail 411 near the flipping unit 3. A rope is connected to the slider 412 and is wound around the pulley 413. A counterweight is suspended at the lower end of the rope. Relying on the counterweight, the slider 412 tends to move closer to the flipping unit 3, so that the arc-shaped piece 46 can cooperate with the blocking plate 44 to restrict the five-pack of goods. When there are no five-pack of goods between the blocking plate 44 and the arc-shaped piece 46, the arc-shaped piece 46 will return to the position close to the receiving plate 316 under the action of the counterweight.

[0081] Furthermore, a spring 414 is connected between the side of the arc-shaped piece 46 near the receiving plate 316 and the slider 412. The arc-shaped piece 46 is rotatably mounted on the slider 412. When the five-pack of goods is pushed from the receiving plate 316 onto the buffer plate 41, the five-pack of goods contacts the arc-shaped piece 46 and first pushes the arc-shaped piece 46 to rotate. The spring 414 then makes the arc-shaped piece 46 adhere tightly to the five-pack of goods, resulting in a better limiting effect on the five-pack of goods. When the arranging plate 42 pushes the five-pack of goods, the five-pack of goods can push the arc-shaped piece 46 to rotate, allowing the five-pack of goods to detach from the arc-shaped piece 46. Then, the elastic force of the spring 414 allows the arc-shaped piece 46 to return to its original position.

[0082] In this embodiment, a height limiting plate 48 is provided above the buffer plate 41, and the arrangement plate 42 and the arc-shaped piece 46 are located between the height limiting plate 48. The height limiting plate 48 can limit the five-pack of goods and prevent the five-pack of goods from tilting up.

[0083] In this embodiment, the bag-making unit 5 is similar to the bag-forming mechanism of patent 201911031182.8. The bag-making unit 5 can construct a packaging bag and connect the bag opening with the output end of the buffer plate 41.

[0084] After the product is pushed into the packaging bag by the arrangement plate 42, the packaging bag with the product will reach a conveyor belt. Then the sealing unit 6 seals the sides and ends of the packaging bag. The sealing unit 6 includes a side sealing mechanism and a horizontal sealing mechanism. The side sealing mechanism and horizontal sealing mechanism of patent 201911031182.8 can be referred to, or other sealing mechanisms can be used to seal the packaging bag.

[0085] In this embodiment, the second driving component 43 is a linear module.

[0086] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
