Description

The utility model relates to the manufacturing industry, in particular to machines (conductors) for assembling parts and finished wooden structures used for the transportation and storage of various goods, vegetables, building materials, namely pallets, boxes, lids, flooring, etc.

A device is known for manufacturing pallets on which a plurality of spaced apart longitudinal beams are sequentially arranged, wherein floorboards are fastened together with nails to form pallets, the device comprising a base having a central portion from which first, second, third and fourth elongated portions extend outwardly, located at an equal distance from each other, a post of circular cross-section attached to said central portion, a frame assembly that includes four side frames that extend upwardly and inwardly, each of which includes first and second end portions and upper and lower horizontal cross-members, upper and lower bearings rotationally supported in fixed positions on said post, a plurality of upper and spaced apart arms that emanate from said upper bearing and are attached to said upper cross-members, four equally spaced apart horizontal lower arms that extend outwardly from said lower bearing to the centers of said lower cross-members, and a plurality of vertically spaced apart elongated cross-members that extend between said first and The apparatus for producing pallets also comprises means, adjustable by each of said side frames, for removably holding a plurality of stringers in fixed positions on the side frames, including a plurality of parallel, vertically arranged cross members that extend between the first and second end portions of each of the side frames and a plurality of guides, adjustablely positioned on each of the cross portions and second means, adjustablely supported by each of the side frames for removably holding a plurality of boards in a parallel arrangement outside of the stringers and perpendicular to them, and drive means operating on compressed air, connected to a source of compressed air and controlled by means for intermittently rotating the frame assembly (US patent application US 4077106 A, published 07.03.1978).

The main drawback of the known pallet manufacturing device is its low productivity, due to the need for mechanical removal of the finished product from the work surface due to the structural immobility of the pallet assembly work surface. The device is bulky and requires constant rotation, requiring the work cycle of each operator to be coordinated, which can lead to downtime for some operators and constant workload for others. Other disadvantages include the inability to adjust the overall dimensions of the device's workspace and the limited range of finished product sizes, resulting in inefficient use of the production area's workspace. Furthermore, it is impossible to assemble products that exceed the equipment's overall dimensions without modifying the device's design.

A machine for manufacturing pallets with a positioning pallet assembly device is known, including a base and an A-shaped frame, wherein the lower surface of the A-shaped frame is located on the base, a processor and a motor are installed in the base, the motor is connected to the A-shaped frame, which is a vertically fixed cylinder on the side surface of the base, and has a mounting pin equipped with a touch sensor on the outer surface of the base, the bottom of the A-shaped frame is provided with a positioning sleeve matched with the mounting pin, and is additionally fixed on a wedge-shaped contact block (China patent application CN 106239651A, published 12/21/2016).

The disadvantages of the known machine include inefficient use of the work surface due to the inability to place raw materials and fixtures within the machine's internal rotational area, a high risk of injury to machine operators due to the machine's rotation and the need to exit the rotational area each time, as well as low mobility and the impossibility of using the machine outside of specially prepared areas. Furthermore, the machine has a fixed work surface geometry, which limits the maximum size of the finished product, is difficult to reconfigure, and the fasteners used to hold the finished product are unreliable.

The closest technical solution selected is a device for manufacturing wooden pallets, comprising a frame, a nail gun, and a positioning assembly device fixedly and inclined on the frame and comprising a bracket, a positioning frame, and a cylinder, wherein the bracket is fixedly mounted on the frame. The device further comprises a plurality of lower partitions (guides) located on the bracket under the bottom plate, an upper partition at the top of the lower partition and under the top plate, and longitudinal partitions (guides) located on the left and right sides of the bracket (China Utility Model Patent CN 213055225 U, published April 27, 2021).

The disadvantages of the closest analogue, like those of well-known pallet-making machines, include the non-adjustable overall dimensions of the product, the inability to modify the product design (add or remove elements) and overall dimensions, the immobility of the work surface for assembly, and the labor-intensive nature of removing the finished product from the machine's work area. Furthermore, the closest analogue suffers from low reliability due to the large number of installed tools and low maintainability due to the non-removable elements of the positioning device.

The technical problem, the solution of which is provided by the utility model, is the creation of a device for assembling wooden structures (a jig) with high productivity and maintainability, with minimal labor intensity and an increased range of manufactured products and safety when working on the jig due to the creation of a telescopic design of the jig frame and the ability to rotate (tilt) the jig frame relative to the jig bed, which increases the convenience of work, simplifies the removal of finished products and makes it possible to dump them on the other side of the jig and organize the storage of finished products, eliminating the possibility of the frame tipping over onto workers.

The technical result of the utility model is to increase the performance of the device.

The technical result is achieved in that a jig for assembling wooden structures comprises a bed, a frame mounted on the bed with longitudinal and transverse guides, according to the utility model the bed has an A-shape, wherein the frame is made with the possibility of rotation relative to the bed and is pivotally connected to the latter, wherein carriages with rollers with the possibility of longitudinal movement are installed inside the longitudinal guides, the guides are made with roller supports and mechanisms for fixing the carriages to the guides, located on the ends of the guides.

The technical problem was solved by developing a jig for the production of wooden structures, based on the ability to change the angle of the frame relative to the bed, i.e., its tilt by 270°. This was made possible by the special design of the A-frame bed, consisting of beams connected at an angle, and the frame being attached to the bed by pivots, such as bearing assemblies. Furthermore, the jig design utilizes a telescopic method for adjusting the work surface size. The frame contains roller guides and sliding carriages mounted on both sides, along with mechanisms for securing the carriages to the frame to rotate the work surface. This jig design allows for adjustment of the product's linear dimensions without modification, as well as safe and easy frame rotation (with a force of 7 kg), and simplified removal of the finished product.

The utility model is illustrated by images (Figs. 1-13) of an example jig for manufacturing wooden structures. These examples, while not the only possible ones, clearly demonstrate the possibility of achieving the claimed technical result. However, the provided examples of the claimed utility model do not limit its implementation possibilities and are not exhaustive.

According to the utility model, the jig for assembling pallets comprises a frame 1, on which a frame 2 is mounted, comprising longitudinal guides 3 and transverse guides 4 (Fig. 1, 3, 8, 11). The longitudinal guides 3 are oriented along the axis of rotation of the frame 2 relative to the frame 1. The transverse guides 4 are oriented perpendicular to the axis of rotation of the frame 2 relative to the frame 1. The frame 1 comprises support beams 5, which are connected at an angle, forming an A-shaped shape of the frame 1 (Fig. 1, 2, 5). The frame 2 is configured to rotate relative to the frame 1 and is pivotally connected to the latter, for example, by means of bearing assemblies 6. The bearing assemblies 6 are fixed on the top of the A-shaped frame 1 (Fig. 2, 4). The longitudinal guides 3 are provided with roller supports 7, which are mounted on the ends of the guides 3 and are necessary for reducing rolling friction during movement of the carriages 8 (Fig. 6, 7). Carriages 8 with rollers 9 (Fig. 3, 9, 10) are mounted in the longitudinal guides 3 with the possibility of longitudinal movement. The transverse guides 4 are mounted on the ends of the carriages 8 and are intended for fixing the placement of horizontal and transverse floorboards for assembling manufactured parts or products on the working surface of the frame 2. Mechanisms 10 for fixing the carriages 8 to the guides 3 are provided on the ends of the longitudinal guides 3. The mechanism 10 may comprise a handle 11, pressure plates 12 and a bolt 13 (Fig. 8, 13). Dividers 14 moving along longitudinal grooves 15 located on the transverse guides 4 (Fig. 11) can be used to fix the elements of the part or product.

The jig for assembling wooden structures works as follows.

On the declared jig, various wooden structures (products) can be assembled, in particular, pallets, boxes, lids, flooring, etc. Before starting work, the jig operator loosens the locking mechanism 10 of the carriages 8 using the corresponding handle 11 controlling the mechanism 10 of the carriage 8 on the left and right. After this, the linear dimension required for the production of the part is set using a measuring tool, then the operator fixes the position of the carriages 8 using the same handles 11. On the resulting working surface, the necessary additional devices (installation dividers 13, guides, diagonals, limiters, clamps, etc.) are installed for rigid fixation of the elements of the wooden structure being assembled (Fig. 11). Wooden blanks 16 of the structure being manufactured are placed on the resulting working area of the frame 2, which are subsequently fastened together using drum nails driven in with a pneumatic hammer (Figs. 11, 12). After assembling the structure, the operator rotates frame 2 using control handle 17 to the opposite side to remove the finished product. Frame 2 is then returned by moving handle 17 in reverse (Fig. 1, 5). The pallet assembly and removal cycle then repeats.
