Abstract

According to the present invention, there is provided a method of assembling a corrugated pallet having two die-cut corrugated cardboard blanks forming a pallet top and a pallet bottom, wherein each of the pallet top and the pallet bottom has at least one vertically extending double thickness rib, The rib has at least one notch, and when the upper portion of the pallet and the lower portion of the pallet are vertically stacked together, the notch locks the opening of the opposite ribs. In performing the method, a mixture of mechanical and human performance processes is used. The machine forms a rib on each blank by applying in-plane pressure to the blank through a mechanical projecting element that engages the blank and moves relative to each other, and the machine moves the upper and lower portions of the pallet together The pressure in the plane is maintained so as to prevent the ribs from being opened until a predetermined time. The machine uses a rib-folding plate that exerts an out-of-plane force on the blank to assist in the formation of the rib by rotating in an out-of-plane direction when an in-plane compressive force is applied. The human operator loads the blank onto the machine and forms the sidewall and fork openings.

Description

PROCESS FOR ASSEMBLY OF CORRUGATED PALLET [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet for transporting merchandise, and more particularly, to a method of assembling a corrugated pallet that enables manufacture of a high-capacity pallet with minimal assembly operator fatigue and minimized assembly machine cost. The method increases manufacturing reliability and reduces the time required to assemble the pallet.

Pallets are said to travel all over the world. 80% of the trade is carried in pallets. The pallet industry is estimated to be over $ 30 billion worldwide. More than 500 million pallets are manufactured annually in the United States, and 1.8 billion pallets are used in the United States alone.

Pallets are formed from a variety of materials, but wood pallets account for about 80% of the current market. Currently, over 4.0% of the world's hardwood timber is used for the manufacture of wood pallets. Other materials used in the manufacture of pellets include plastics, metals and cardboard.

Recent regulations on contamination and contamination are causing interest in surge and the use of non-wood pallet alternatives. The small but fast-growing sector is the use of corrugated pallets. Various requirements to replace conventional wood pallets with corrugated pallets: Increase recyclability, reduce pallet weight, eliminate product contamination, reduce pallet storage volume, and reduce pallet related injuries.

Until now, cardboard pellets of different designs have been developed. Despite the possible advantages of corrugated pallets, they have suffered from several different drawbacks. The drawbacks include low strength and stiffness, and frequent use of corrugated cardboard results in high material costs with high overhead, assembly labor and transportation costs. The inherent inability to easily produce and dispense corrugated pallets in sufficiently high volumes has also become very important.

Regardless of the design, it is desirable to increase the speed at which corrugated pallets can be produced. The corrugated pallets can be assembled only by hand or by machine. When assembled grossly, the assembly time may be longer than some of the frequent use cases and / or acceptable to the customer. When assembled in a machine, the assembly speed can be increased, but the size and cost of the assembly machine increases, which eventually upsets the assembly and allows the operation ratio to be higher than desired for some customers and / or parts of the world do. Therefore, there is a need for a new corrugated pallet assembly method that can be used to easily produce corrugated cardboard pallets in large quantities, at high speeds and at the same time with low assembly costs.

Currently there are two general types of corrugated pallets; The first type comprises a block or runner consisting of corrugated board laminated, rolled and / or assembled and then joined to the upper and lower decks, and the other type comprises two sheets folded together and assembled together to form an upper, a lower and an integral vertical support . The first type typically utilizes a large corrugated cardboard and is expensive. Adding more weight to higher material costs is complex and time consuming assembly, which is typically done at an intermediate location, adding more logistics costs.

A second general type of corrugated cardboard pallet, formed of two sheets and having an integral vertical support between the two sheets, is preferred due to the use of much less unique boards. Regardless of the particular design, assembly is typically accomplished in three steps: top forming, bottom forming, and subsequent top and bottom together. Though lower material costs result in less cost than the first type of cardboard pellets, manufacturing is still too time consuming, complicated, and expensive.

The main object of the present invention is to provide a method of assembling a corrugated cardboard pallet that enables high-volume pallet manufacturing at a high speed and at a low assembly cost. The Applicant has found that there are different folding and assembling processes in the assembly of corrugated cardboard pallets and that some of these processes are difficult to be carried out quickly and repeatedly by the human body. These processes are also easily carried out by a machine. Applicants have also found that some processes in assembling corrugated cardboard pallets are difficult to perform by the machine due to the required mechanical complexity and resulting reduced reliability and greatly increased machine cost. The Applicant has found that these processes, which are difficult to carry out by a machine, are surprisingly easily carried out by the human hand. Thus, this aspect of the disclosed preferred embodiment of the present invention provides a method of increasing the assembly speed by utilizing the synergy that the pallet assembly is shared by the use of both mechanical and gauge assembling functions, and to reduce the cost associated with corrugated pallet assembly . For example, a process that is difficult for a person but is easy for a machine is completed by a machine, and a process that is difficult for a machine but easy for a human is completed by a human. In the assembly method, the assembly function may vary between the machine and the scales several times for optimum efficiency.

The assembly method reduces the time required to assemble the pallet, reduces assembly costs, minimizes assembly operator fatigue and minimizes the complexity of the assembly machine.

Another object of the invention is to integrate the assembly so that the method can be simplified and the steps can be eliminated. For example, in a preferred embodiment, the formation of ribs may be integrated with assembling the top and bottom of the pellet together. Prior art two-part pellets have a rib or a vertical support which is prevented from opening by the adhesive and / or the mechanical locking part constructed independently on each individual member. For example, in U.S. Patent No. 6,029,582, individual ribs are locked together using a jack flap and a sliding lock assembly. U.S. Patent No. 7,462,890 teaches locking ribs using a folded flap lock assembly that is locked before superimposing the top and bottom of the pallet using slots and wing taps. U.S. Patent No. 7,890,184 teaches using a gate flap and locking a support rib through a hole. U.S. Pat. No. 7,303,519 teaches a machine for forming top and bottom pallets, which prevents the opening of ribs through the use of adhesives. In each case, the independently locked ribs provide the advantage of a robust rib that can remain unaffected even if the pallet is partially disassembled.

However, the disadvantage of self-locking ribs is that additional steps and complicated assembly methods are required. The Applicant has found that the assembly of the pallet bottom blank and the overlaid pallet upper flank can be sufficient to keep the ribs locked during use of most of the pallets. Locking the rib open in this way is accomplished by a notch in the upper rib that locks the opening of the lower rib and a notch in the lower rib that locks the opening of the upper rib. Completion of the pallet side is utilized to hold the pallet top and pellet bottom blank together so that the ribs remain locked together. Additional device requirements are desirable where the ribs at the top and bottom are pressed and held in a folded state until the top and bottom coalesce together. However, with considerable mechanical complexity and size reduction involved, the time for pallet assembly and self-locking of individual ribs can be eliminated. A preferred embodiment of the present invention provides a method of assembling a corrugated cardboard pallet using a machine and a mixture of processes performed by a floss. Examples of corrugated cardboard pellets that can be assembled by the method of the present invention include two die cut corrugated cardboard blankes forming the top of the pallet and the bottom of the pallet. Each of the ribs having at least one notch, wherein when the upper portions of the pallet and the ribs on the lower portion of the pallet are vertically superposed together, . Machines operating in accordance with the present invention form ribs on each blank by applying in-plane pressure to the mechanical blank piercing projecting elements that penetrate the blank or engage the edges of the blank and move relative to each other, The machine maintains the in-plane pressure to lock the opening of the ribs for a period of time after the top of the pallet and the bottom of the pallet are superimposed together. The use of projecting elements or fins through the blank allows a sufficiently high in-plane compressive force for reliable folding of the ribs.

The pallet assembly method preferably takes up a minimal amount of space for both the reduction of the floor space required and also the size and cost reduction of the assembly machine. Applicants have found that a preferred embodiment of the present invention allows ribs to be formed on the top and bottom of the pallet while the blanks are aligned in the vertical direction in the horizontal position such that the top and bottom of the pallet are assembled together vertically at the same location Respectively. In another embodiment of the present invention, the machine forms a rib on both the pallet top and the pallet bottom, with the top of the pallet and the bottom of the pallet together to effect the forming and superimposition without one or two complete planar movements of the blanks Overlap

For simplicity of machine construction, it is desirable to keep the blank from only one side instead of two sides. Bearing the blanks from the top side and from the bottom side significantly complicates the superposition of the pallet top and the bottom of the pallet at the same location as the assembly because mechanical parts must always be positioned between the two blanks. In order to allow the upper part of the pallet and the lower part of the pallet to overlap, the aforementioned mechanical parts must be moved or the blank must be moved. In another embodiment of the present invention, the machine utilizes a vacuum to maintain each blank in a fixed position while the projecting elements provide in-plane pressure. In this case, the upper blank is supported using a vacuum from the upper side, and the lower blank is supported using a vacuum from the bottom side. The pins through each blank move toward one another to provide in-plane compression for rib folding. The in-plane pressure is maintained until the upper and lower portions are superimposed together.

During the folding of the ribs at the top of the pallet and at the bottom of the pallet through the application of in-plane compression, the ribs tend to fold in the right direction or 180 degrees in the opposite direction. For example, the rib from the upper blank must be folded down to extend downward and the rib from the bottom blank must be folded up to extend upward. In order to assist in folding in the desired out-of-plane direction, it is desirable to apply an out-of-plane force to the ribs. In another embodiment, the machine further comprises a rib-folding plate that applies an out-of-plane force to the blank by rotating in an out-of-plane direction when an in-plane pressure is applied to assist rib formation. The out-of-plane force can be applied by a number of different means, but using a rib-folding plate that moves in an out-of-plane direction forms a simple mechanical configuration. More preferably, the machine further includes a rib-folding plate that applies a planar lateral force to the blank by rotating about a fixed axis in an out-of-plane direction when in-plane compression is applied to assist rib formation.

The drawback to this method is that once the folded plate is once rotated in the vertical direction it is trapped between the two sides of the rib when folded. Surprisingly, Applicants have found that this can be advantageous in that it can be used to more accurately maintain the ribs in the vertical direction for easier superposition of the pallet top and the bottom of the pallet. After the pallet assembly is completed, the pallet may be removed from the rib-folding plate in a vertical direction to remove the pallet from the machine. In another embodiment of the present invention, once the rib-folding plate is formed, it remains in the rib until the top of the pallet and the bottom of the pallet co-lap together.

The assembly method of maintaining the in-plane pressure to lock the ribs open to the board memory until the top and bottom are superimposed eliminates the need for a stand-alone rib lock or adhesive. Adhesives not only add significant cost and machine complexity, but also reduce machine reliability. Adhesives also require curing time. Likewise, the integral mechanical rib lock on each blank will require the machinery to engage within the space between the pallet top and the pallet bottom, preventing the top of the pallet and the bottom of the pallet from overlapping at the same site. In another embodiment, the assembly method does not utilize the integral corrugated mechanical or adhesive locking of the ribs from the opening prior to the superimposition.

The method of assembling the corrugated cardboard pallets can be completed by both man and machine for minimization of assembly cost and ease of assembly. Some work is best done by the machine, and the other work is best done by the scales. The formation of the ribs and superposition of the top and bottom together are best done by the machine. Blank loading and sidewall folding are best accomplished by hand in many cases because they are handmade by hand, which is more difficult to automate. In a further embodiment of the present invention, at least one person loads the blank on the machine, the machine forms the ribs, the machine stacks the pallet top and the pallet bottom together, and at least one person places the side wall of the pallet in a planar outward direction Fold.

The machine size for use with the disclosed method of assembly is minimized through the use of rib folding that occurs with blanking. The assembly method is more complex and potentially slower than conventional waveform folding performed by, for example, moving the blank completely over a fixed mandrel on the conveyor belt. In another embodiment, the machine forms a rib on the blank and is fixed in a fully translational direction, by rotating both the upper pallet and / or the lower pallet so that the upper and lower ribs are perpendicular to each other, By moving the bottom portions toward each other in a plane outward direction, the upper portion of the pallet and the lower portion of the pallet are folded together. Of course, the upper and lower blanks have portions that move inward in the plane during each rib formation but, of course, remain completely fixed for in-plane translational motion.

1 to 3, of which FIG. 1 shows a preferred embodiment of a method for assembling a corrugated cardboard pallet according to the present invention. Method 30 includes step 31, i.e., blanks 101, 102, to the pallet assembling machine 60 by hand. In one embodiment illustrated in FIG. 2, one person (denoted by icon 53) loads the upper blank and another person (denoted by icon 54) loads the lower blank from the opposite sides of the machine. Loading a blank from a non-uniform and misaligned stack is very easy by the scales, but difficult by the machine. After the blanks are loaded, the next step 32 is to fold the ribs on the upper and lower blanks 101, 102, which is preferably done by a machine because each blank is gripped simultaneously Or it is difficult to do it quickly by hand. The third step 33 is to rotate the upper blank by 90 degrees relative to the lower blank so that the upper and lower blanks can be assembled together in a vertical direction. This step is easily performed by the machine. After rotation, the fourth step 34 compresses the upper and lower blanks 101, 102 together. Compression is best performed by the machine because it can assemble the top to the bottom with a force of 100 lbs, and each rib can be completely collapsed together. The fifth step 35 is folded and pushed in the sides 1, 3, which is difficult by the machine due to the complexity of the operation and the required accuracy, but is easily handled by the scissors since the required force is small. The sixth step 36 opens the fork window of the sides 1, 3, which is easily done by the thumb. The seventh step 37 is to rotate the top and bottom together by 90 degrees so that the sides 2, 4 are completed. This step is easily performed by the machine. The eighth step 38 is preferably folded and pushed in the side portions 2 and 4, and is also preferably performed by flossing. The ninth step 39 is to insert the fork window into the sides 2, 4, which is easily handled, in which case the machine will require considerable mechanical complexity. The last step in method (30) is to lock the corner strap (40). This process can be done relatively easily by a machine or a scraper.

A top view of a setup for implementing the method of FIG. 1 for assembling a corrugated cardboard pallet according to the present invention is shown in FIG. The setup 50 includes a stack 51 of upper blanks 101, a stack of lower blanks 102 and two human operators 53 and 54. The operators 53 and 54 load the blanks 101 and 102 with the pallet assembling machine 60. The machine 60 includes a vertical beam support 61 and an upper cantilevered support 62. The upper blank is loaded into the upper frame 63. The assembly method may alternatively be carried out by placing two sets of blanks 51, 52 on the same side of the assembly machine and then one operator 53 loading the two blanks one by one.

A side elevational view of the pallet assembling machine 60 shown in Fig. 2 for assembling a corrugated cardboard pallet according to the present invention is shown in Fig. The assembly machine is preferably operated by a pneumatic cylinder and the pneumatic cylinder is omitted from the drawing for the sake of simplicity and clarity of the overall machine function. The assembly machine is preferably operated by a sensor that senses when the upper blank 101 and the lower blank 102 are loaded. A sensor-not shown-initiates the initiation of a rib forming timing sequence, which is activated by a programmable logic controller. The sensor may be a blank sensor or alternatively a foot switch activated by the assembly operator.

The assembling machine 60 includes a vertical beam support 61, an upper cantilever support 62 and a bottom support 67. The upper frame 63 is supported under the upper cantilevered support 62 by bearings 64 to allow rotation of the upper portion of the pallet. On the upper frame 63 there is provided a slide support 65 which is used to grasp the upper blank 101 and supports a three row vacuum cup 66 sliding together while two parallel ribs are formed in the upper blank 101 Is mounted. As the vacuum cup 66 inhales the upper blank 101 against the stop, the element 74 engages the upper blank 101 at the edge to apply a pressure in the plane for folding the ribs, 66 slide inward to hold the portions of the upper blank as they move inward toward each other.

The bottom frame 68 is supported on the bottom support 67 via the lift connection mechanism 72 and the bottom bearing 69. On the bottom frame 68 there is provided a slide support 70 which is used to grip the bottom blank 102 and which supports three rows of vacuum cups 71 that slide together and form two parallel ribs of the bottom blank 102 Is mounted. When the vacuum cup 71 sucks down the bottom blank 102 against the stop, the element 75 engages the bottom blank at the edge to apply a pressure in the plane to fold the rib, Maintains a portion of the upper blank in a plane while the portions of the upper blank are moving inward toward each other while the ribs are being formed. The upper and lower blanks 101 and 102 form the ribs and are compressed together in the vertical direction by the lifting connection mechanism 72. After the side walls are manually assembled the corner straps of the pallets are moved by the arms 73 Is assembled on the assembling machine (60). The corner strap may alternatively be manually assembled by a floss.

4 is a perspective view of a corrugated cardboard pallet assembled in accordance with the present invention. The pallet 100 is composed of two sheets of corrugated paperboard including a pallet top portion and a pallet bottom portion which are folded together. The Applicant contemplates corrugated cardboard pallets of other configurations that can be assembled according to the present invention. The pallet 100 may have a four-way entry opening or a two-way entry opening for a fork or pallet jack used to move the pallet.

Fig. 5 shows the corrugated board pallet 100 shown in Fig. 4 in a flat blank condition. The pallet 100 comprises an upper blank 101 and a lower blank 102. The blanks 101,102 are die cut so that they are easily and accurately folded to form the finished pallet. The die for cutting the blanks 101, 102 is provided with cuts and marks on the blank.

6, the pallet 100 shown in Figs. 4 and 5 obtains an internal vertical support structure by the vertical ribs 103, 104 in which the vertical ribs 103, 104 are folded over the pallet top and bottom portions 102 . The notch 110 in the bottom rib 104 prevents the top rib 103 from opening when the top pallet 101 is vertically overlaid with the bottom pallet 102. Similarly, when the pallet upper portion 101 and the pallet bottom portion 102 are superposed together vertically, a notch-not shown-in the ribs of the pallet upper portion 101 prevents the bottom ribs 104 from opening .

In Fig. 7, the upper pallet 101 and the lower portion 102 were rotated 90 degrees and compressed together as shown in Fig. The notches in the ribs 103 cross the corresponding notches 10 in the ribs 104 and are locked in a vertical direction to the corresponding notches. This provides cross support for the pallet 100 and also utilizes each set of ribs 103,104 to prevent them from being opened to each other.

8 shows a corrugated cardboard pallet 100 as shown in the assemblies of Figs. 5 to 7 with side walls folded in accordance with the present invention. After the upper blank 101 and the lower blank 102 have been compressed together, it is preferred that a person or person folds the side wall to complete the side walls 105, 106 of the pallet. This process forms sidewalls 105 from the pallet top 101 and sidewalls 106 from the pallet bottom.

9, there is shown a corrugated cardboard pallet 100 as shown in the assemblies in Figs. 5-8, in which the fork window is opened in accordance with the present invention. After the side walls 105, 106 are folded (steps 35 and 38), the next process (step 39) is to open the fork window in the pallet 100. The pallet top 101 forms a sidewall 105 and cuts and marks in the blank provide a fork opening 107. The pallet bottoms 102 form side walls 106 and the cuts and marks in the blanks provide fork openings 108. The opening 108 is simply opened by urging the blank sidewall to a position where the blank is removed to allow the cardboard to pivot. The last step is to lock the corner locking portion 109 which extends from the upper blank 101 and overlaps the bottom portion of the bottom blank 102 to abut the bottom portion of the bottom blank. The corner locking portions shown on the bottom blanks 102 are not used to maintain a smooth upper portion for the pallet 100 in this embodiment.

In Fig. 10A, a schematic diagram of the configuration of the folding section of the pallet assembling machine of Fig. 3 is shown before folding the ribs. The folding section 120 is folded in the vertical direction to fold the double thickness ribs 131 and 132 into the bottom blank 102. [ Before folding the ribs, the blank 102 is flat. The blank 102 is disposed on the folding section 120 by setting the blank on the projection 125 on the sliding portions 122 and 123 passing through the blank. An advantage of using the pins 125, 126 through the blank 102 is that the pin can be used to accurately position the blank on the machine and provide a high in-plane pressure for rib folding. The sliding elements 122 and 123 and the central portion 124 have a vacuum cup 71 that draws the blank 102 downward. After penetrating the blank 102, the projections or pins 125,126 exert in-plane compressive forces on the blank via the retaining force because the sliding sections 122,123 are directed toward the center portion 124 Direction. Blank 102 preferably includes a strike 121 that facilitates upward folding of the ribs outwardly and outwardly as shown in Figure 10B. The rib-folding plates 127 and 128 supported by the rotary bearings 129 and 130 contact the blank 102 in the vicinity of the central stalk 121 where the upper ribs of the two ribs are subsequently formed to start the rib-folding . When the in-plane compressive force is applied, the suction cup keeps the non-splicing portion of the in-plane blank 102, and the rib-folding plates 127 and 128 rotate in the vertical direction, applying a planar outward force to the blank, To be folded in the desired direction.

Fig. 10B is a schematic view of the configuration of the folding section of the pallet assembling machine of Fig. 3 after the ribs are folded. The sliding portions 122 and 123 slid inward toward the central portion 214 and the rib folding plates 127 and 128 were rotated in the vertical direction to form the ribs 131 and 132. The rib-folding plates 127, 128 are trapped within the double thickness ribs 131, 132 and keep them correctly vertical so that the upper and lower blanks are easily assembled together later. After the pallet is completed, the vacuum is removed from the vacuum cup 71, and the pallet is moved in the vertical direction by the rib-folding plates 131, 132 and the projections 125, 126 .

Obviously, numerous modifications and variations of the described preferred embodiments are possible, and will occur to those skilled in the art in light of the present disclosure. Accordingly, the Applicants contemplate that these modifications and variations and equivalents thereof will fall within the scope of the present invention And are intended to be included within the spirit and scope of the invention.
