Definitions
- the invention relates to an apparatus and method for weighing and labeling items, and more particularly for weighing and labeling items which rest on nonflat bottoms, such as whole poultry in bags while such items are transported by conveyor in a high speed weighing and labeling operation.
- Wobble or oscillation by itself may not present a problem if it is being transported merely to get to a destination, but when the purpose of the transport is to weigh and label the bird, unreliability and inaccuracy will most likely occur.
- a wobble in the weighing operation will result in an incorrect weight.
- a wobble in the labeling operation will result in an improperly positioned label.
- the wobble on a flat open conveyor belt frequently results in an orientational misalignment of the product, further disturbing label location.
- the conventional conveyor is one which has a basically flat horizontal belt, or similar supporting surface, and transports the product through the operative stations.
- the conveyor system may be a series of short conveyors working in sequence.
- Such a multiple sequence conveyor apparatus for weighing and labeling is exemplified by the HI 2600 made by New Brunswick International, Inc. of Lilburn, Ga. Wobble is very likely to occur in this sort of system when the product does not have a flat bottom.
- the label may be applied differently from item to item. Naturally, the more uniform the label placement, the more acceptable the product. This situation is exacerbated by a design feature of many current conveyor weighing devices which, in order to separate items so only one is at the weighing station at a time, will run the three sections at successively increased speeds.
- a “nonflat" bottom refers to a bottom surface of a product on which the product rests and which supports the product in a manner which is somewhat unstable and may tend to permit the product to wobble on a conveyor.
- an object of the present invention is to improve the accuracy and reliability of weighing of conveyor weighed products with nonflat bottoms.
- a further object of the present invention is to improve the label placement accuracy of all shaped products labeled in a conveyorized operation.
- An additional object of the present invention is to maintain better control of the products being weighed and labeled at current process speeds and further increased speeds likely to occur in the near future.
- An apparatus for the weighing and labeling of products with nonflat bottoms in a conveyorized, automated high-speed process in which there is a separate conveyor section for each function, each section having a pair of adjustable spaced vertical control belts mounted perpendicular to the horizontal conveyor belt on which the product rests and commonly driven therewith.
- the perpendicularly mounted pair of control belts have resilient surfaces and are positioned and adjusted to grip the nonflat bottom product to prevent oscillating and mispositioning due to high-speed handling to avoid inaccurate weighing and poor label placement.
- FIG. 1 is a perspective view of the weighing and labeling apparatus according to the present invention illustrating the multiple process sequence of entry, weighing and labeling.
- FIG. 2 is a plan view of the apparatus of FIG. 1 further depicting a bagged whole bird poultry product being processed at each operating section.
- FIG. 3 illustrates the irregular outline of a typical whole bird poultry product as seen from the foot end being moved through a conveyor of the invention as viewed along line 3--3 of FIG. 2 with further detail of the space adjusting mechanism.
- FIG. 4 is a plan view which portrays one arrangement for spring biased rollers for maintaining a firm gripping contact of the control belts on the product.
- FIG. 5 is a plan view which illustrates the invention as applied to the transporting, weighing and labeling of a product in a tray.
- an automatic high-speed process as shown in FIG. 1 has three operative stations designated A, B and C.
- Station A is the entry section for transporting the product to the following sections for processing
- Station B is the weighing operational section
- Station C is the operational station for printing and applying a label to the product.
- Station A of FIG. 1 has a substantially horizontal, flat, mechanically driven conveyor belt 10 extending from the entry end of the apparatus and continuing to transport the products to Station B.
- rear control belt 12 mounted in a plane perpendicular to conveyor belt 10 in fixed relation thereto is rear control belt 12, driven in the same direction and at the same speed as conveyor belt 10.
- front control belt 16 mounted parallel to rear control belt 12 is front control belt 16, which is adjustable in its proximity to rear control belt 12 through a mechanism depicted in FIG. 4 to accommodate various sizes of poultry.
- the entry ends of both control belts 12 and 16 form an outwardly directed angle in relation to the main planes of belts 12 and 16 to allow the product P to be guided automatically into the main conveyor path.
- Any suitable drive mechanism may be employed to drive the belts 10, 12 and 16 and such mechanism is not shown to better illustrate the invention.
- the product P Upon leaving Station A, the product P is aligned with the main path of the conveyor 10.
- a commonly used system operates the conveyor belt of weighing Station B at a speed greater than that of entry Station A to drive a first product P through Station B before a second product P has emerged from Station A.
- the belt of the labeling Station C is run at a speed greater than that of weighing Station B.
- Station B It is possible to operate Station B at the same speed as Station A, or to design the machine with Station A and Station B combined into one section. This method would result in a loss in processing speed, because the first product would have to exit the weighing section before the second product is permitted to enter the weighing station.
- Station B has a substantially horizontal, flat conveyor belt 30 and rear control belt 26 mounted perpendicular in fixed relation thereto.
- Front control belt 28 is mounted adjustable spaced from and parallel to rear control belt 26. Adjustment between control belts 26 and 28 is accomplished in a similar manner to the adjustment between control belts 12 and 16 in Station A.
- Conveyor belt 30 and control belts 26 and 28 all operate at the same speed, that being somewhat faster than the speed of the belts in Station A so that the product P is physically separated on Station B for unitary weighting.
- a conventional drive mechanism such as employed to drive belt 30 may be readily adapted to drive belts 26, 28 and is not shown for purpose of better illustrating the invention.
- Station B functions to measure the weight of the product P and then send information relative to this weight to Station C for label imprinting.
- Weighing control device 32 of Station B as is known in the art, is electrically connected to Station B and to the label printing and applying apparatus 42 of Station C.
- Station C has substantially horizontal, flat conveyor belt 40 and rear control belt 36 mounted perpendicular thereto in fixed relation.
- Front control belt 38 is mounted adjustably spaced from and parallel to rear control belt 36 and is adjustable in a similar manner to the mechanisms of Stations A and B.
- the three operative belts of Station C run at equivalent speeds and direction to each other and at a speed somewhat faster than that of the belts of Station B.
- a conventional drive mechanism, not shown, may be readily adapted.
- the speed differential is again achieved in order to assure that only a single product P at a time is present on the weighing station.
- Station C has a label imprinting apparatus 42 which receives the weight information from the weighing device in Station B, imprints a label and applies the imprinted label to the product P.
- a product sensing switch or photoelectric cell placed along Station B to cue the label printer in Station C for readiness.
- a product sensing switch will detect the product P as it passes a point in the system and signal to another point in the system that according to the speed of the transport means in the system the product P will arrive at the second point at a given time relative to the time it has passed the first point.
- FIG. 2 shows the weighing/labeling apparatus of the invention with the addition of the product P being processed.
- the poultry product P is seen in Station A being aligned and moved toward Station B; in Station B being weighed and move toward Station C; and in Station C being labeled and moved out of the apparatus.
- Station B weighing to be reliable, the poultry or other nonflat bottom product must be controlled to avoid oscillation as is accomplished by the invention.
- Station C label application to be properly positioned, the product must be maintained in a precise placement, which is accomplished by the present invention.
- a standard flat conveyor will not satisfy either of these needs.
- the large difference in size between one type of product and another will be accommodated by the adjusting means of changing the space between the rear fixed control belt 12, 26, or 36 and the respective front adjustable control belt 16, 28, or 38.
- This will not however, be sufficiently flexible to adequately grip all birds with the minor size variations as will occur within a class, such as that of a four pound and a five and one-half pound chicken.
- One embodiment to enable proper gripping of the poultry product as shown in FIGS. 1, 2 and 3 is directed to control belt 12 and control belt 16 being made of a resilient, relatively thick material so as to achieve controlled gripping of the poultry or other irregular product.
- the vertical control belts of Stations B and C are constructed similarly.
- FIG. 3 An end view of the apparatus illustrates the effective gripping of the irregular product as shown in FIG. 3.
- the basic irregularity of the poultry product P is illustrated to emphasize the value of the resilient surfaces of control belts 26 and 28.
- the resilient, relatively thick belt materials compress to grip and transport the product P without slippage or wobbling.
- the view of FIG. 3 is typical of any of the three sections of the invention with regard to both the handling of an irregularly shaped product and the mechanism for adjusting the spacing of the control belts.
- FIG. 3 also shows a detailed view of a spacing adjustment and weight detecting system which may be utilized to vary the basic spacing between front and rear control belts 26 and 28.
- Crank 22 is rotated manually, which turns lead screw 20, connected to a lower corner of the control belt 26 assembly.
- Sprocket mounted timing chain 24 connects screw 20 to operate synchronously an identical screw 20a (FIG. 2) connected to the opposite lower corner of front control belt 26 thereby adjusting the spacing between control belts 26 and 28 while maintaining parallelism therebetween.
- the screws 20 are assembled to engage threaded blocks 25 which support control belt 28.
- load cells 23 are electrically connected and transmit data to a signal processor comprising a microprocessor or computer 32 and then to label imprinter 40 at Station C of FIGS. 1 and 2.
- the weight signal generated by load cells 23 are fed to the signal processor 32 which by conventional means deducts the equipment weight and produces a net product weight which si fed to the labeling apparatus 42.
- FIG. 4 An alternate means of maintaining grip on the sides of products of non-uniform weight and irregular shape is illustrated in FIG. 4 as a series of rotatably mounted rollers 52 within the loop of thin control belt 50 and springs 56 biased on pivoted arms 54, the arms and springs being arranged so as to force rollers 52 against the inner surface of belt 50.
- a product passes the control belt 50, it successively compresses the rollers 52 which press inwardly against springs 56 resistance, firmly holding the poultry product.
- the present invention is related to the commonly utilized system having multiple conveyor belts operating at successively increasing speeds to isolate the product being weighed in the weighing station. It is to be understood that other conveyorized systems which may have only a single conveyor belt would benefit equally from the principle contained herein of eliminating wobble for more accurate weight and label placement.
- the tray is transported in the prior art conveyorized machinery, on a flat driven belt. Control of the movement and position of the product depends on friction between the bottom of the tray and the belt. If there should be some grease or water on the belt, or if there is significant difference in the weight of the product, slippage could occur. This is particularly true because it is desirable and usual to operate the belt of Station C faster than that of Station B, which is running faster than the belt of Station A, as previously discussed. As can be readily appreciated, the change in speed of the belts will frequently instigate slippage.
- the present invention provides a means for gripping the sides of the tray containing the product between relatively thick, resilient control belts and positioning the tray for label application more precisely.
- a tray 60 of wrapped product is transported along the conveyor system from a relatively low entry speed in Station A to an intermediate speed in Station B to a maximum speed in station C.
- the tray 60 leaves Station B, it is still being held between control belts 26 and 28.
- the forward portion of the tray comes in contact with control belts 36 and 38 at Station C and the bottom of the tray is shown transferring from flat conveyor belt 30 of Station B to flat conveyor belt 40 of Station C.
- a means of aiding reliable handling between Station B and C is to adjust the control belts 36 and 38 of Station C in closer proximity than are belts 26 and 28 of Station B, thereby achieving controlled gripping in passing from Station B to Station C.
