Description

[Technical Field]

[0001] The present invention relates to a processing station for transporting and processing discrete products that are transported across a processing section. In this process, multiple similar products (production lots, also referred to as batches) are often processed in a single operation, after which the product type or required processing may change. [Background technology]

[0002] Various processing methods are known that work in conjunction with the product during processing. This is, for example, a reading unit that captures product markings. Additionally, inspection units that test specific characteristics of a product are also conceivable. Furthermore, attaching markings to products also falls under such processing steps. In many cases, products are moved in the transport direction X to the effective range of the processing means using a transport unit, such as a transport belt or similar transport means, and in many cases, it is necessary to specifically align or position the product relative to the processing means in order for the processing to be successful.

[0003] Therefore, for example, the print head of the printing unit is moved and / or aligned toward the product with respect to the product, particularly perpendicular to the transport direction X, so that the printing process can be carried out with a desired Y distance between the product and the print head. Alternatively, the initially arbitrarily positioned product may be rerouted and / or aligned with the stationary print head by first moving from the conveyor belt of the supply unit to a lane extending along the print head across a lane change section, and then reaching the processing means in an optimal position or arrangement for processing.

[0004] However, if, for example, the movement of the print head is obstructed by the transport belt, preventing the print head from moving freely in the lateral direction Y perpendicular to the transport direction X, the above configuration may become difficult. On the other hand, lane change sections require additional, costly installation space along the transport path of the processing section. Furthermore, in many cases, auxiliary means are needed that cooperate effectively with the processing means during product processing. Furthermore, since this auxiliary means often needs to take a specific position relative to the product during processing, it becomes even more difficult to correctly position the product, processing means, and auxiliary means.

[0005] Patent Document 1 describes a control system that includes a central control unit connected to multiple sensors in order to capture processing parameters in real time. This control system incorporates actuators that are controlled by a control unit based on collected data to optimize the functionality of industrial processing. This configuration allows for precise adjustment and control, focusing on improved efficiency and flexibility.

[0006] Patent Document 2 describes a processing apparatus comprising a processing chamber consisting of a base body and a holding device attached thereto. The holding device is configured to reliably hold the object to be processed. A locking device is incorporated to secure the object inside the processing chamber and ensure accurate positioning. The structure of this locking device is designed to provide both stability and user-friendliness, and is suitable for easy installation and maintenance.

[0007] Patent Document 3 describes a workpiece handling device comprising a base plate, a support column provided vertically on the base plate for structural support, a rotating arm attached to the support column for rotating the workpiece, and a gripping mechanism at the end of the rotating arm for gripping and holding the workpiece. The drive unit controls the movement of the rotating arm and the gripping mechanism. With this configuration, accurate positioning and efficient handling of the workpiece in industrial applications become possible.

[0008] From Patent Document 4, a device having a base structure to which a holding device is attached is known. This holding device is used to hold the workpiece or object in a stable position. Also, this device has a control mechanism capable of accurately adjusting the holding device. The purpose is to ensure improvement in the handling and positioning of the workpiece, and it is configured for simple operability and versatility.

Summary of the Invention

Problems to be Solved by the Invention

[0010] Therefore, an object of the present invention is to provide a processing station that overcomes the above - mentioned disadvantages. The present invention is achieved by the processing station according to claim 1 and the method according to claim 9. Further advantageous embodiments will become apparent from the dependent claims.

Means for Solving the Problems

[0011] The present invention is based on the insight that the processing means can be collectively shifted in the lateral direction Y as part of the processing unit together with the auxiliary means and the conveying unit, so that the product can be positioned with respect to the processing means for its current processing. Accordingly, according to the present invention, before the product to be processed reaches the conveying unit, the processing unit or its conveying unit can be moved to a Y position that can be predetermined so as to succeed in the processing. By skillfully selecting the Y position, the product reaches the conveying unit at an optimal lateral position for subsequent processing.

[0012] Here, the processing unit is part of the processing station according to the present invention, and is configured to convey and process discrete products in the product flow, extending in a conveying direction X, a lateral direction Y that is orthogonal to this and usually extends in a horizontal direction, and a height direction Z that is orthogonal to the conveying direction and usually extends in a vertical direction. The processing station includes a base body that is fixedly arranged during normal operation, for example, a machine frame arranged on the floor of the facility, and this base body is configured to receive and fix various components of the processing station.

[0013] The processing station includes a processing unit, and this processing unit itself includes a conveying unit, at least one processing means, and at least one auxiliary means assigned to this at least one processing means. The conveying unit is configured to convey the product over a conveying surface formed by the conveying unit in the conveying direction X. For example, the upper side regarded as the flat surface of the conveyor belt of the conveying unit can form the conveying surface.

[0014] The processing means is configured to process the product while the product is being conveyed by the conveying unit or while it is stopped temporarily. In particular, processing means that require a predetermined distance between the processing means and the product for processing are contemplated.

[0015] Here, "processing" in its broadest sense is understood as each interaction specifically generated between a product and a processing means, used to generate, alter, or capture the characteristics of the product. Furthermore, in this case, product markings should be understood as product characteristics, and reading existing markings or attaching new markings to a product constitutes capturing or generating product characteristics. Here, for example, inspecting a product using a camera to obtain information about specific product characteristics through image evaluation should be understood as capturing product characteristics, and for example, inspecting a product using X-rays to capture the X-ray characteristics of the product, to detect foreign objects in the product, to identify layer thickness, to detect filling amount, to conduct integrity tests and leak tests, etc. In contrast, the mere presence or orientation of a product at a specific location on a transport surface, which can be captured using a sensor, should not be understood as a characteristic according to the above definition. Therefore, for example, the distance between the product and the sensor when using a photoelectric sensor is generally trivial. Furthermore, inductive or capacitive sensors, for example, that are used solely for the simple detection of a product despite having specific distance requirements, should not be understood as means of capturing product characteristics.

[0016] Auxiliary means assigned to a specific processing means are used to assist, or in particular to enable, the processing of products by the processing means. For example, as an auxiliary means, a guide member can be considered to align or guide the product during processing. In particular, the guide member plays a role in stabilizing the product so that it does not shift laterally in the Y direction while the processing means is, for example, applying a mark to the product. Providing a marking to a product may involve attaching a label or indication to the product, which is done on the side opposite to the guide member of the product. Here, the guide member ensures that the product is guided by a predetermined small Y distance relative to the processing means during marking application, thereby enabling the application of high-quality markings to the product.

[0017] An embodiment in which multiple processing means are provided is conceivable. For example, a processing unit can include both a printing unit and a camera. In addition, it is conceivable that the processing unit may be equipped with multiple auxiliary means, and each of the multiple auxiliary members may be assigned to a different processing means or to only one processing means. For example, the guide member can serve to guide the product in the lateral direction Y both during the marking process and during inspection using a camera before or after, thereby preventing the product from deviating from the camera's focal range during processing.

[0018] Alternatively, the first auxiliary means may simply guide the product during the marking process, while the second auxiliary means, configured as a light shield or illumination device, assists or optimizes image capture by the camera. In this case, these two auxiliary means are each assigned to different processing means.

[0019] According to the present invention, at least one processing means and at least one auxiliary means assigned to this at least one processing means each extend at least partially above the conveying surface, thereby enabling or facilitating the processing of the product. According to this embodiment, at least one processing means extends at least partially below the conveying unit or conveying surface, thereby preventing the conveying unit from freely shifting the processing means in the lateral direction Y, particularly toward the product P located on the conveying surface.

[0020] According to the present invention, at least one processing means and at least one auxiliary means assigned to this at least one processing means for processing a product are fixed to the processing unit on two sides of the product facing each other in the lateral direction Y. Therefore, during processing, the processing means and the assigned auxiliary means receive the product between them, and the processing means on one side of the product and the opposing auxiliary means cooperate with each other to properly perform the processing.

[0021] The core of this invention is that the processing means and the auxiliary means assigned to this processing means are configured to be movable in the lateral direction Y relative to a fixed base body, together with the transport unit. According to the present invention, this relative movement allows the product to be supplied to the processing unit to be received at a predetermined Y position on the conveying surface, and then the product can be conveyed and processed by passing it between the auxiliary means and the processing means.

[0022] The ability of the processing unit, auxiliary unit, and transport unit to move together allows for particularly flexible adjustments to accommodate various product sizes and the lateral Y-direction supply position of the product. Therefore, as is clear from the illustrated example, the processing unit can receive the product to be supplied to the processing unit at a selectable Y position, or it can receive it on the transport surface of the transport unit. Furthermore, there is no need to change (i.e., adjust) the position of the processing means relative to this transport unit for this purpose. Furthermore, while the auxiliary means maintains its own position relative to the transport unit or processing means, all three units can shift together in the lateral Y direction while remaining substantially fixed relative to each other, so as to shift to the Y position necessary to receive the product to be supplied to the transport unit.

[0023] On the other hand, this shift-together configuration does not preclude the pre-preparation of processing units, for example, as batches or for processing specific product types that need to be handled in large quantities. In this case, it may be necessary to first adjust the auxiliary means and / or processing means, and then position and fix them in the lateral direction Y relative to the transport unit. For example, guide members as auxiliary means and / or printing units as processing means can first be adjusted to the width of the product to be printed by shifting each laterally and then fixing them in place before the processing operation begins. If the lateral position (receiving position) where the product is introduced into the transport unit is known, the processing unit can be moved laterally in the Y direction relative to the base body. This allows one side of the received product, which is the target of printing, to pass directly through the print head of the printing unit, while the opposite side is guided and stabilized by a pre-positioned and fixed guide member. For all further products of the same product type, there is no need to shift the entire processing unit laterally, nor is there any need to adjust the relative positions of the processing means, auxiliary means, and transport unit.

[0024] According to an embodiment of the present invention, the processing station includes a supply unit located upstream of the processing unit, which is configured to transport products to a transport unit. The supply unit may be equipped with a conveyor belt or similar conveying means, and the product is transported along this conveying means in the conveying direction X toward the conveying unit and delivered to the conveying unit. According to the present invention, since the processing unit can be shifted relative to the supply unit, the product can be transferred from the supply unit to the transport unit at a Y position selectable in the transport direction X in a straight line or lane, and there is no need to change lanes or shift the product itself laterally on the supply unit or transport unit for subsequent processing.

[0025] Unlike the processing unit, the supply unit can be fixed in place and connected to, for example, the base body of the processing station. Shifting the supply unit in the Y direction, i.e., laterally, is neither necessary nor useful for realizing the present invention because even if the apparatus according to the present invention is configured in reverse (i.e., even if a fixed processing unit and a laterally shiftable supply unit are provided), the objective of the present invention cannot be achieved. This is because, in this case, the supply unit would need to reposition each individual product being transported on it by shifting it laterally relative to the processing unit located downstream. As a result, the transport capacity of the supply unit would be severely limited, and continuous movement would be required.

[0026] Instead, the processing unit is movable laterally in the Y direction relative to the supply unit, so that the product sent from the supply unit is transferred from the supply unit to the transport unit or the transport surface formed by the transport unit at a selectable Y position.

[0027] According to embodiments of the present invention, the processing station is supported by a guide, in particular a linear guide, the guide itself being connected to a base body. For example, the guide may comprise a lower part connected to the base body and an upper part acting as a carriage that is movable laterally in the Y direction relative to the lower part and connected to the processing unit. The guide allows for manual operation, for example, by the operator moving the carriage laterally before starting the processing operation and fixing it in this position. Alternatively, the guide may be further equipped with a drive mechanism and may operate automatically, for example, with a control device that automatically adjusts the lateral position to which it should approach for processing, depending on the product to be processed and the processing method.

[0028] The processing means can be configured, for example, as a printing unit. The printing unit can be configured, for example, to print on the side of the product that protrudes from the transport surface using markings. Furthermore, by configuring the markings to be mounted slightly above the transport surface, it is conceivable that the print head could also be positioned slightly above the transport surface. For this purpose, it may be necessary to position the printing unit at the edge of the transport surface so that a portion of the printing unit can extend below the transport surface. In this case, the processing unit can be positioned laterally in the Y direction with respect to the upstream supply unit such that the product moves from the supply unit to the supply unit at the edge of the conveying surface or at the end of the conveying belt of the supply unit. For this purpose, the auxiliary means configured as guide members are adjusted and fixed in the processing unit according to the product width, so that the product is placed on the end of the conveyor belt and conveyed by passing through the print head and guide members, or passing between the print head and guide members, without rotating while staying as close as possible to the print head and guide members. Furthermore, as with all other processes, the application of markings or printing, such as inkjet printing, can be performed while the product is being transported by the conveyor unit or while the conveyor belt is temporarily stopped.

[0029] Furthermore, the processing means can be configured as an inspection unit. This should also include means of capturing markings attached to the product, specific shape features, and product dimensions. This includes, for example, cameras, RFID sensors, barcode scanners, and QR code scanners. Herein, X-ray equipment for capturing specific product characteristics or X-ray imaging characteristics, such as X-ray equipment for detecting product heterogeneity or foreign matter, filling level measurement, and light transmission inspection, such as X-ray equipment for sealing seam inspection, should also be included in the group of inspection units. In the case of X-ray inspection, the operating means may be, for example, a scintillator, or other sensor or detector that detects X-rays, and an X-ray source can be considered as an auxiliary means related thereto. In this case, these two components can be positioned opposite each other in the lateral direction Y, and the product being transported passing between them can be inspected ("side view").

[0030] Furthermore, an ejector capable of discharging individual products from the conveying flow can also be considered as a processing method. In this case, the discharge member is rotatable or movable above the conveying surface, and by applying force laterally to the product using impact, it moves the product downward from the conveying surface. As a related auxiliary means, a guide member can be provided to guide the product, which has been acted upon by the steering member, downward from the conveying surface to, for example, a container located adjacent to the conveying unit.

[0031] According to an embodiment of the present invention, the auxiliary means is configured as a guide member that guides the product being transported on the transport surface in the lateral direction (lateral Y). For this purpose, the guide member has a guide surface that allows the product to slide along and to adhere to the conveyor belt when it is temporarily stopped. Furthermore, the guide surface plays a role in preventing the product from rotating or shifting on the conveying surface. Preferably, the guide surface extends in the conveying direction X. Furthermore, the guide surface is preferably flat. Most preferably, the guide surface extends in the XZ plane. Guide members may be useful for various processing methods that require guiding of the product during processing. This includes attaching the marking to the side of the product opposite the guide surface, and in particular, when a lateral Y force is applied to the product during processing (e.g., during label application), the guide member receives and compensates for this force. Furthermore, the guide member prevents the product to be inspected using image recognition from changing position in the lateral Y direction during processing, for example, by keeping the product within the camera's focal range, thus enabling accurate acquisition of image data.

[0032] Alternatively or additionally, they may be configured as auxiliary means, light shields, backlight devices, members protecting against electromagnetic radiation, windbreaks, reflective means, lighting means, or other components specifically provided to enable or facilitate the processing of products by each processing device, with each processing device directly assigned to it.

[0033] Furthermore, according to a further embodiment of the present invention, the auxiliary means may be configured as a further processing means. Therefore, for example, a product can be photographed from two sides using two opposing cameras, or a camera can work with the product to capture an image on the opposite side while printing is being done on one side. Furthermore, it is conceivable to use two printing units to attach, for example, two markings to two opposing sides of a product, with each auxiliary means functioning as a guide member for the printing unit simultaneously being part of the opposing printing unit. Furthermore, it is conceivable to use the two cameras on opposite sides in the lateral direction Y, and the guide member, which functions as an auxiliary means for the first camera, can simultaneously support the second camera. Furthermore, the second camera can capture the features of the upper side of the product, which is opposite to the transport surface.

[0034] Preferably, at least one processing means and / or at least one auxiliary means are manually or automatically adjustable and fixed in the lateral direction Y and / or the height direction Z. This allows the processing unit to be adjusted to accommodate products of various dimensions and diverse processing requirements. For example, the height of the marking attached to the product can be adjusted by fixing the processing means, which is configured as a printing device, to the required height.

[0035] The processing station according to the present invention itself has a base body which is fixed and, for example, a common frame on which a processing unit can be moved and a supply unit can be fixedly attached. Here, it is preferable to limit the processing unit, which is movable in the lateral direction Y relative to the base body, to the components necessary to realize the principle of the present invention of lateral shifting (at least one processing means, a transport unit, and at least one auxiliary means) as much as possible. In contrast, it is preferable that further mechanical components, such as a housing protecting all or part of the processing station, associated control cabinets, control devices, operating terminals, or display units, be fixed and connected to the base body, because lateral shifting of these components is not directly necessary to implement the concept of the present invention, and the mass to be shifted is small.

[0036] The transport unit of the processing unit can satisfy the requirements for implementing the present invention as long as it can transport the product to be processed between the processing means and the auxiliary means. In this case, preferably, the conveyor belt has a continuous belt surface. On the other hand, alternatively, other conveying devices or conveying principles can be considered depending on the product being conveyed. Therefore, as long as the proper transport of the product and the lateral shift of the processing unit due to the transport principle do not adversely affect the implementation of the present invention, a belt transport device, roller transport device, or chain transport device equipped with multiple parallel-extending belts can also be used. Furthermore, the supply unit can be implemented based on various conveying devices known to those skilled in the art, as long as it can transfer the product to the conveying unit.

[0037] The processing station according to the present invention may include additional conveying members positioned above the conveying surface to assist in the transport of products. Therefore, an additional transport unit can be placed above the transport unit so that the product can be transported while being sandwiched between the upper and lower transport units. In this case, the upper transport unit, also called the upper runner, is part of the processing unit and can be shifted laterally in the Y direction along with the lower transport unit, processing means, and auxiliary means. Furthermore, the upper runner itself can be shifted laterally and fixed relative to the processing unit and / or base body, allowing it to be positioned according to a specific product type. Furthermore, the upper runner can be equipped with additional processing means, such as a printing device configured for the upper side of the product, a camera, and the like. When the upper runner or means attached thereto assists processing by other processing means, the upper runner can be understood in the broadest sense as an auxiliary means.

[0038] A method for processing a product (P) using a processing station (T) according to the present invention uses the processing station and supply unit described above and comprises the following steps. 10) A step of positioning the processing unit laterally relative to the supply unit according to the position where the product should be supplied onto the supply unit when it is handed over to the transport unit. 20) A step of transporting at least one product using a supply unit, automatically transferring the product to a transport unit of a processing unit, then transporting the product in the transport direction, and processing the product with processing means and auxiliary means assigned to the processing means.

[0039] After performing step 10), step 20) can be immediately repeated for subsequent products of the same type or the same process, and there is no need to make new adjustments or lateral shifts each time after step 10). Here, it is assumed that each product is always transported by the supply unit at the same lateral position in order to reach the transport surface at the delivery position that served as the basis for adjustment according to method step 10).

[0040] In preparing the product for processing, according to this embodiment of the method, it is preferable to perform the following steps before step 10). 05) A step of positioning at least one processing means and auxiliary means assigned to at least one processing means in the lateral Y direction relative to a transport unit, depending on the product to be transported, in particular a step of adjusting the lateral Y distance between at least one processing means and auxiliary means assigned to at least one processing means.

[0041] This ensures that the distance between the processing means and / or auxiliary means to the product, and / or the distance between them, is adjusted to suit the subsequent processing. This step only needs to be performed once for each batch of similar products and can be substituted with step 10) depending on the product supply.

[0042] This embodiment of the method relates to using a guide member, whose guide surface substantially extends in the transport direction X, as an auxiliary means. Here, method steps 05 and / or 10) are performed under the following conditions: i) A portion of the first outer surface of the product is aligned with the guide surface when it is delivered to the transport surface by the supply unit, so that the product is guided laterally by the guide member after being delivered to the processing unit. and / or ii) A portion of the second outer surface of the product takes a predetermined Y position on the transport surface after being handed over to the processing unit, which is necessary for processing by the processing means.

[0043] For example, when printing on the side of a product using the support of a guide member, first, the distance Y between the guide surface of the guide member and the processing means (e.g., print head) is determined. DH You can set this distance Y DH Since this essentially corresponds to the lateral Y width of the product to be processed, the first surface of the product is guided accurately and closely along the print head. This adjustment can be performed, for example, by shifting the guide element to a predetermined distance from the print head in the lateral Y direction and fixing it to the processing unit in this position. In this case, there is no need to shift the print head in the same way; for example, it can even be permanently fixed to the processing unit. In this configuration, where the processing unit "print head," transport unit, and auxiliary means "guide element" are relatively fixed to each other, they can all be shifted laterally in the Y direction relative to the base body as part of the processing unit.

[0044] Here, the processing unit can be positioned relative to the supply unit such that the second surface of the product received from the supply unit, opposite to the first surface in the lateral direction Y, passes very close to the print head during further transport, thereby enabling the generation of a high-quality print image on this second surface. For this specific application (printing), the processing station is precisely adjusted to the width of the product and the product's feeding position by method steps i) and ii). Furthermore, for example, during product inspection using a camera, the processing unit can be shifted to receive the product at the exact Y position on the transport surface, guiding it through the camera's focal range as it is further transported by the transport unit.

[0045] In the case of X-ray inspection, it is preferable to position the product so that all the light emitted from the X-ray source is directed at the product and the product is X-rayed across its entire vertical extent. Furthermore, it is preferable that the X-ray source and the X-ray detector are positioned relative to each other so that the light rays emitted from the X-ray source in a fan shape to X-ray image the product make maximum use of the size of the X-ray detector located behind the product. This is shown in Figure 6.

[0046] In the case of similar processing regarding the positioning requirements described above, the product can be transferred from the supply unit to the transport unit in a straight lane and processed there.

[0047] Embodiments of the present invention will be described in detail below with reference to the illustrated examples. [Brief explanation of the drawing]

[0048] [Figure 1] A perspective view showing a first embodiment of the present invention. [Figure 2] This figure shows an embodiment of Figure 2 after the processing unit has been shifted laterally. [Figure 3] A simplified plan view of the apparatus shown in Figure 1. [Figure 4] A simplified plan view of the apparatus shown in Figure 2. [Figure 5] A perspective view showing a second embodiment of the present invention. [Figure 6] A schematic diagram showing X-ray irradiation of a product. [Modes for carrying out the invention]

[0049] Figure 1 shows a simplified perspective view of the processing station T according to the present invention, which extends in the horizontal transport direction X, the horizontal lateral direction Y perpendicular to this direction, and the height direction Z perpendicular to both of these directions.

[0050] The processing station T is partially shown and is positioned on a base body G which is configured as a frame and fixed, and this base body G can be attached, for example, to the floor of a manufacturing facility.

[0051] The base body G is then fitted with a supply unit A that is fixedly connected to the base body G, and the product P is transported in the transport direction X using this supply unit A. Furthermore, processing unit B is located immediately downstream of supply unit A. Processing unit B has a transport unit M, which is configured to transport product P in the transport direction X, and for this purpose receives product P from supply unit A located upstream. Furthermore, each of these supply unit A and transport unit M is equipped with an endless transport belt. The upper surfaces of each conveyor belt are flush with the surface at the same height, and the conveyor belt of conveyor unit M defines a conveyor surface E on its upper surface.

[0052] Processing unit B includes a first processing means D1 configured as a printing unit, which includes a print head D1 (not shown in detail), and this print head D1 is closely connected to a transport surface E in the lateral direction Y. The printing unit D1 extends both above and below the transport surface E. Furthermore, processing unit B includes a second processing means D2 configured as a camera, and this second processing means D2 is positioned in close proximity to the first processing means D1 and immediately upstream of it. Furthermore, camera D2 is closely connected to the transport surface E on the side and similarly extends both upward and downward. Apart from these illustrated solutions, it is also conceivable to place camera D2 downstream of another processing device, for example, to inspect the quality of a printed image attached just upstream.

[0053] On the opposite side of the transport unit M, viewed in the lateral direction Y, is the guide member H. F An auxiliary means is provided, which is configured as such and includes a guide surface F that substantially extends in the XZ plane. This guide member H F This is used to guide or stabilize product P in the lateral direction Y while product P is being photographed by camera D2 and printed by printing unit D1. In this way, guide member H F This is assigned to both camera D2 and printing unit D1, and supports both of these processing means during their respective processes.

[0054] Also, guide member H FThe position can be freely adjusted in the lateral direction Y relative to the transport unit M or to processing means D1 and D2, and can be fixed using two clamping rails which are not specified in detail. Also, guide member H F It can be shifted in the direction of the printing unit D1 or camera D2 to be positioned above the transport surface E rather than to the side.

[0055] Processing means D1, processing means D2, transport unit M, and guide member H F The processing unit B, which is equipped with a linear guide L that can be manually operated by a handwheel, is connected to a linear guide L that can be freely shifted in the lateral direction Y relative to the base body G and therefore relative to the supply unit A. Processing unit B can optionally be fixed at each selected shift position along the linear guide L using fixing means not shown in detail, in order to prevent unintended shifts. Alternatively, for example, a threaded spindle of a linear guide L can achieve the required fastening using sufficient friction or self-locking.

[0056] In Figure 1, product P is positioned approximately in the center of supply unit A, and can be seen being supplied to transport unit M from this lateral position. This position is disadvantageous, at least for processing using the printing unit D1, because when the product P is transported on the transport surface E, the print head does not reach the side of the product P facing the printing unit D1. Printing is impossible in this manner.

[0057] In contrast, as can be seen in Figure 2, thanks to the ability of the processing unit B to move relative to the base body G or supply unit A according to the present invention, it becomes possible to change the lateral position to one that is advantageous to the printing process and to receive the product P. For this purpose, the processing unit B is shifted by a displacement ΔY in the lateral direction Y using the linear guide L. As a result, the product P reaches the conveying unit M at the end of the conveyor belt or the conveying surface E, and thus the product P can be delivered to this conveying unit M. At this time, the side surface of the product to be printed will reach the printing head D1 at the closest distance required for printing.

[0058] Figures 3 and 4 show the principle according to the present invention in a simplified plan view of the conveying surface E. Here, Figure 3 shows a case where the product P can be delivered from the supply unit A to the conveying unit at the correct lateral position, that is, at the left end of the supply unit A as viewed in the conveying direction X, so that printing can be performed on the product P using the printing unit D1. Therefore, there is no need to shift the processing unit B laterally with respect to the base body G or the supply unit A.

[0059] Also, in Figure 3, a guide member H having a guide surface F is provided so that the product P is guided laterally during its further conveyance and processing and is guided to pass through the printing head of the printing unit D1 almost without play. F It can be seen that it is pre-positioned and fixed in the lateral direction Y.

[0060] A camera provided as a further processing means D2 is positioned and fixed in the lateral direction Y via positioning means not shown in detail so that a part of the product P, that is, the product P which is the object of the camera shooting, is located within the focus range of the camera.

[0061] In contrast, Figure 4 shows a case where the product P at the right end of the supply unit A as viewed in the conveying direction X is introduced into the processing unit B. Furthermore, in order to enable the product P to be transferred to the transport unit M at the lateral position shown in Figure 3 and processed there, the processing unit B is shifted by a displacement ΔY relative to the base body G or supply unit A according to the present invention, thereby linearly transferring the product P to the transport unit M, where it can be processed at a predetermined or required separation distance.

[0062] Figure 5 shows a simplified alternative embodiment of the present invention, where repeated reference numerals correspond to the respective above-described components. A processing device T can be seen, which comprises a supply unit A, a processing unit B located downstream of it, and an output belt (not shown in detail) located further downstream. Unlike the supply unit A and the discharge belt, the processing unit B can also be shifted laterally in the Y direction relative to the base body G in this case as well. The inspection device D2, which is configured as a camera, is positioned to the side of the transport surface E, and is positioned just above it. In this case, it is used as a processing means to capture the product P supplied to the transport surface E using image recognition means. On the opposite side of the transport surface E facing camera D2 in the lateral direction Y, there is an auxiliary means that cooperates with camera D2, and a light-shielding body H L They are arranged in this configuration. This light shield H L However, blocking, at least partially, the diffusion of light emitted from the lighting equipment essential to the Camera D2 is usually necessary because this is flash light that would be a hindrance to the operator.

[0063] These include camera D2, transport unit M, and light shield H. L The processing unit B can be shifted laterally in the Y direction by the present invention so that the product P supplied by the supply unit A is located within the focal range of the camera D2.

[0064] Figure 6 shows a simplified representation of product P undergoing X-ray inspection, viewed from the perspective of the transport direction X. For this purpose, auxiliary means H configured as an X-ray source RQ The X-ray beam is directed in a fan shape in the lateral direction Y, and aligned with the processing means configured as an X-ray detector D3. In this process, the X-ray beam passes through the product P being transported on the transport unit M in the YZ plane and reaches the X-ray detector D3, and the intensity of each X-ray beam increases or decreases according to the X-ray imaging characteristics of the product P. To completely X-ray image the entire product P, the processing unit, which includes a transport unit M, is shifted in the lateral direction Y so that the product P is transported to a position Y1 that is suitable for optimal X-ray imaging, rather than an unfavorable lateral position Y0. To make optimal use of the size of detector D3, X-ray source H RQ The Y-distance to [the object] has been pre-adjusted. In this way, product P is completely X-rayed, and the X-ray beam reaches detector D3 across its entire available vertical capture range. [Explanation of Symbols]
